You should carefully consider the risks described below before making an investment decision, as well as the risks and other information included and incorporated by reference in the applicable prospectus supplement when determining whether or not to purchase the securities offered under this prospectus and the applicable prospectus supplement.

2

The risks and uncertainties described below are not the only risks and uncertainties we face.  Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may impair our business operations.  If any of the following risks actually occur, our business, results of operations and financial condition could suffer. In that event, the trading price of our common stock could decline, and you may lose all or part of your investment in our common stock.  The risks discussed below also include forward-looking statements and our actual results may differ substantially from those discussed in these forward-looking statements.

Risks Relating to our Operations


Our insurer that provides

Failure to maintain our financial assurance coverage that we are required to have in order to operate our permitted treatment, storage and disposal facility has experienced financial difficulties.


It has been publicly reported that American International Group, Inc. (“AIG”), has experienced significant financial difficulties and is continuing to experience significant financial difficulties.  A subsidiary of AIG provides ourfacilities could have a material adverse effect on us.

We maintain finite risk insurance policies and bonding mechanisms which provide financial assurance to the applicable states for our permitted facilities in the event of unforeseen closure.closure of those facilities. We are required to provide and to maintain financial assurance that guarantees to the state that in the event of closure, of our permitted facilities will be closed in accordance with the regulations. The policies provide a maximum of $35,000,000 ofIn the event that we are unable to obtain or maintain our financial assurance coverage of which the coverage amount totals $32,515,000 at December 31, 2008.  In March 2009, the policies were increased to provide a maximum of $39,000,000 of financial assurance coverage of which the coverage amounts totals $37,936,000.  This additional increase was the result of additional financial assurance coverage requirement for our DSSI subsidiary to commercially store and dispose of PCB wastes under a permit issued by the EPA on November 26, 2008.  The AIG subsidiary also provides other operating insurance policies for the Company and our subsidiaries.  In the event of a failure of AIG,any reason, this could materially impact our operations and our permits which we are required to have in order to operate our treatment, storage, and disposal facilities.


If we cannot maintain adequate insurance coverage, we will be unable to continue certain operations.


Our business exposes us to various risks, including claims for causing damage to property and injuries to persons that may involve allegations of negligence or professional errors or omissions in the performance of our services. Such claims could be substantial. We believe that our insurance coverage is presently adequate and similar to, or greater than, the coverage maintained by other companies in the industry of our size. If we are unable to obtain adequate or required insurance coverage in the future, or if our insurance is not available at affordable rates, we would violate our permit conditions and other requirements of the environmental laws, rules, and regulations under which we operate. Such violations would render us unable to continue certain of our operations. These events would have a material adverse effect on our financial condition.


The inability to maintain existing government contracts or win new government contracts over an extended period could have a material adverse effect on our operations and adversely affect our future revenues.


A material amount of our Nuclear Segment'sTreatment and Services Segments’ revenues are generated through various U.S. government contracts or subcontracts involving specifically the U.S. government. Our revenues from governmental contracts and subcontracts relating to domestic governmental facilities within our Nuclear Segmentsegments were approximately $43,464,000$34,811,000, or 70.3%, and $30,000,000, representing 57.6% and 46.5%$37,019,000, or 74.4%, respectively, of our consolidated operating revenues from continuing operations for 20082018 and 2007.2017, respectively. Most of our government contracts or our subcontracts granted under government contracts are awarded through a regulated competitive bidding process. Some government contracts are awarded to multiple competitors, which increase overall competition and pricing pressure and may require us to make sustained post-award efforts to realize revenues 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 to maintain or replace these relationships, or if a material contract is terminated or renegotiated in a manner that is materially adverse to us, our revenues and future operations could be materially adversely affected.

Failure of our Nuclear Segment to be profitable could have a material adverse effect.

Our Nuclear Segment has historically been profitable. With the divestitures of certain facilities within our Industrial Segment and the acquisition of our Perma-Fix Northwest Richland, Inc. (“PFNWR”) within our Nuclear Segment in June 2007, the Nuclear Segment represents the Company’s largest revenue segment. The Company’s main objectives are to increase focus on the efficient operation of our existing facilities within our Nuclear Segment and to further evaluate strategic acquisitions within the Nuclear Segment. If our Nuclear Segment fails to continue to be profitable in the future, this could have a material adverse effect on the Company’s results of operations, liquidity and our potential growth.

Our existing and future customers may reduce or halt their spending on hazardous waste and nuclear services with outside vendors, including us.


A variety of factors may cause our existing or future customers (including the federal government) to reduce or halt their spending on hazardous waste and nuclear services from outside vendors, including us. These factors include, but are not limited to:


 ·accidents, terrorism, natural disasters or other incidents occurring at nuclear facilities or involving shipments of nuclear materials;
 ·failure of the federal government to approve necessary budgets, or to reduce the amount of the budget necessary, to fund remediation of U.S. Department of Energy (“DOE”)DOE and U.S. Department of Defense (“DOD”)DOD sites;
 ·civic opposition to or changes in government policies regarding nuclear operations; or
 ·a reduction in demand for nuclear generating capacity.capacity; or
failure to perform under existing contracts, directly or indirectly, with the federal government.

These events could result in or cause the federal government to terminate or cancel its existing contracts involving us to treat, store or dispose of contaminated waste and/or to perform remediation projects, at one or more of the federal sites since all contracts with, or subcontracts involving, the federal government are terminable upon or subject to renegotiation at the option of the government on 30 daysdays’ notice. These events also could adversely affect us to the extent that they result in the reduction or elimination of contractual requirements, lower demand for nuclear services, burdensome regulation, disruptions of shipments or production, increased operational costs or difficulties or increased liability for actual or threatened property damage or personal injury.


Economic downturns (i.e. the current economic recession) and/or reductions in government funding could have a material negative impact on our businesses.


Demand for our services has been, and we expect that demand will continue to be, subject to significant fluctuations due to a variety of factors beyond our control, including the current economic recession and conditions, inability of the federal government to adopt its budget or reductions in the budget for spending to remediate federal sites due to numerous reasons, including, without limitation, the substantial deficits that the federal government has and is continuing to incur. During economic downturns such as the current economic recession, and large budget deficits that the federal government and many states are experiencing, the ability of private and government entities to spend on waste services, including nuclear services, may decline significantly. Although the recently adopted economic stimulus package provides for substantial funds to remediate federal nuclear sites, we cannot be certain that economic or political conditions will be generally favorable or that there will not be significant fluctuations adversely affecting our industry as a whole.  In addition, ourOur operations depend, in large part, upon governmental funding, particularly funding levels at the DOE. Significant reductions in the level of governmental funding (for example, the annual budget of the DOE) 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.


The loss of one or a few customers could have an adverse effect on us.


One or a few governmental customers or governmental related customers have in the past, and may in the future, account for a significant portion of our revenue in any one year or over a period of several consecutive years. Because customers generally contract with us for specific projects, we may lose these significant customers from year to year as their projects with us are completed. Our inability to replace the business with other similar significant projects could have an adverse effect on our business and results of operations.

4

As a government contractor, we are subject to extensive government regulation, and our failure to comply with applicable regulations could subject us to penalties that may restrict our ability to conduct our business.


Our governmental contracts, which are primarily with the DOE or subcontracts relating to DOE sites, are a significant part of our business. Allowable costs under U.S. government contracts are subject to audit by the U.S. government. If these audits result in determinations that costs claimed as reimbursable are not allowed costs or were not allocated in accordance with applicable regulations, we could be required to reimburse the U.S. government for amounts previously received.


Governmental contracts or subcontracts involving governmental facilities are often subject to specific procurement regulations, contract provisions and a variety of other requirements relating to the formation, administration, performance and accounting of these contracts. Many of these contracts include express or implied certifications of compliance with applicable regulations and contractual provisions. If we fail to comply with any regulations, requirements or statutes, our existing governmental contracts or subcontracts involving governmental facilities could be terminated or we could be suspended from government contracting or subcontracting. If one or more of our governmental contracts or subcontracts are terminated for any reason, or if we are suspended or debarred from government work, we could suffer a significant reduction in expected revenues and profits. Furthermore, as a result of our governmental contracts or subcontracts involving governmental facilities, claims for civil or criminal fraud may be brought by the government or violations of these regulations, requirements or statutes.

We are a holding company and depend, in large part, on receiving funds from our subsidiaries to fund our indebtedness.

Because we are a holding company and operations are conducted through our subsidiaries, our ability to meet our obligations depends, in large part, on the operating performance and cash flows of our subsidiaries.

Loss of certain key personnel could have a material adverse effect on us.


Our success depends on the contributions of our key management, environmental and engineering personnel, especially Dr. Louis F. Centofanti, Chairman, President, and Chief Executive Officer. The loss of Dr. Centofanti could have a material adverse effect on our operations, revenues, prospects, and our ability to raise additional funds.personnel. Our future success depends on our ability to retain and expand our staff of qualified personnel, including environmental specialists and technicians, sales personnel, and engineers. Without qualified personnel, we may incur delays in rendering our services or be unable to render certain services. We cannot be certain that we will be successful in our efforts to attract and retain qualified personnel as their availability is limited due to the demand for hazardous waste management services and the highly competitive nature of the hazardous waste management industry. We do not maintain key person insurance on any of our employees, officers, or directors.


Changes in environmental regulations and enforcement policies could subject us to additional liability and adversely affect our ability to continue certain operations.


We cannot predict the extent to which our operations may be affected by future governmental enforcement policies as applied to existing laws, by changes to current environmental laws and regulations, or by the enactment of new environmental laws and regulations. Any predictions regarding possible liability under such laws are complicated further by current environmental laws which provide that we could be liable, jointly and severally, for certain activities of third parties over whom we have limited or no control.


The refusal to accept our waste for disposal by, or a closure of, the

Our Treatment Segment has limited end disposal site that our Nuclear Segment utilizessites to utilize to dispose of its waste which could subject us to significant risk and limitsignificantly impact our results of operations.


Our NuclearTreatment Segment has limited options available for disposal of its nuclear waste. Currently, there are only two disposal sites, each site having different owners, for our low level radioactive waste we receive from non-governmental sites, allowing us to take advantage of the pricing competition between the two sites. If thiseither of these disposal sitesites ceases to accept waste or closes for any reason or refuses to accept the waste of our NuclearTreatment Segment, for any reason, we could have nowherewould be limited to only the one remaining site to dispose of our nuclear waste or have significantly increased costs fromwaste. With only one end disposal alternatives. With nowheresite to dispose of our nuclear waste, we wouldcould be subject to significant risk from the implicationssignificantly increased costs which could negatively impact our results of storing the waste on our site, and we would have to limit our operations to accept only waste that we can dispose of.


operations.

Our businesses subject us to substantial potential environmental liability.


Our business of rendering services in connection with management of waste, including certain types of hazardous waste, low-level radioactive waste, and mixed waste (waste containing both hazardous and low-level radioactive waste), subjects us to risks of liability for damages. Such liability could involve, without limitation:

·claims for clean-up costs, personal injury or damage to the environment in cases in which we are held responsible for the release of hazardous or radioactive materials; and
5

·
claims of employees, customers, or third parties for personal injury or property damage occurring in the course of our operations; and
·
claims alleging negligence or professional errors or omissions in the planning or performance of our services.

Our operations are subject to numerous environmental laws and regulations. We have in the past, and could in the future, be subject to substantial fines, penalties, and sanctions for violations of environmental laws and substantial expenditures as a responsible party for the cost of remediating any property which may be contaminated by hazardous substances generated by us and disposed at such property, or transported by us to a site selected by us, including properties we own or lease.


As our operations expand, we may be subject to increased litigation, which could have a negative impact on our future financial results.


Our operations are highly regulated and we are subject to numerous laws and regulations regarding procedures for waste treatment, storage, recycling, transportation, and disposal activities, all of which may provide the basis for litigation against us. In recent years, the waste treatment industry has experienced a significant increase in so-called “toxic-tort” litigation as those injured by contamination seek to recover for personal injuries or property damage. We believe that, as our operations and activities expand, there will be a similar increase in the potential for litigation alleging that we have violated environmental laws or regulations or are responsible for contamination or pollution caused by our normal operations, negligence or other misconduct, or for accidents, which occur in the course of our business activities. Such litigation, if significant and not adequately insured against, could adversely affect our financial condition and our ability to fund our operations. Protracted litigation would likely cause us to spend significant amounts of our time, effort, and money. This could prevent our management from focusing on our operations and expansion.


Our operations are subject to seasonal factors, which cause our revenues to fluctuate.


We have historically experienced reduced revenues and losses during the first and fourth quarters of our fiscal years due to a seasonal slowdown in operations from poor weather conditions, overall reduced activities during these periods resulting from holiday periods, and finalization of government budgets during the fourth quarter of each year. During our second and third fiscal quarters there has historically been an increase in revenues and operating profits. If we do not continue to have increased revenues and profitability during the second and third fiscal quarters, this willcould have a material adverse effect on our results of operations and liquidity.


If environmental regulation or enforcement is relaxed, the demand for our services will decrease.


The demand for our services is substantially dependent upon the public'spublic’s concern with, and the continuation and proliferation of, the laws and regulations governing the treatment, storage, recycling, and disposal of hazardous, non-hazardous, and low-level radioactive waste. A decrease in the level of public concern, the repeal or modification of these laws, or any significant relaxation of regulations relating to the treatment, storage, recycling, and disposal of hazardous waste and low-level radioactive waste would significantly reduce the demand for our services and could have a material adverse effect on our operations and financial condition. We are not aware of any current federal or state government or agency efforts in which a moratorium or limitation has been, or will be, placed upon the creation of new hazardous or radioactive waste regulations that would have a material adverse effect on us; however, no assurance can be made that such a moratorium or limitation will not be implemented in the future.


We and our customers operate in a politically sensitive environment, and the public perception of nuclear power and radioactive materials can affect our customers and us.


We and our customers operate in a politically sensitive environment. Opposition by third parties to particular projects can limit the handling and disposal of radioactive materials. Adverse public reaction to developments in the disposal of radioactive materials, including any high profile incident involving the discharge of radioactive materials, could directly affect our customers and indirectly affect our business. Adverse public reaction also could lead to increased regulation or outright prohibition, limitations on the activities of our customers, more onerous operating requirements or other conditions that could have a material adverse impact on our customers’ and our business.

We may be exposed to certain regulatory and financial risks related to climate change.

Climate change is receiving ever increasing attention from scientists and legislators alike. The debate is ongoing as to the extent to which our climate is changing, the potential causes of this change and its potential impacts. Some attribute global warming to increased levels of greenhouse gases, including carbon dioxide, which has led to significant legislative and regulatory efforts to limit greenhouse gas emissions.

8
6

Presently there are no federally mandated greenhouse gas reduction requirements in the United States. However, there are a number of legislative and regulatory proposals to address greenhouse gas emissions, which are in various phases of discussion or implementation. The outcome of federal and state actions to address global climate change could result in a variety of regulatory programs including potential new regulations. Any adoption by federal or state governments mandating a substantial reduction in greenhouse gas emissions could increase costs associated with our operations. Until the timing, scope and extent of any future regulation becomes known, we cannot predict the effect on our financial position, operating results and cash flows.

We may not be successful in winning new business mandates from our government and commercial customers or international customers.


We must be successful in winning mandates from our government, commercial customers and commercialinternational customers to replace revenues from projects that we have completed or that are nearing completion and to increase our revenues. Our business and operating results can be adversely affected by the size and timing of a single material contract.


The elimination or any modification of the Price-Anderson Acts indemnification authority could have adverse consequences for our business.


The Atomic Energy Act of 1954, as amended, or the AEA, comprehensively regulates the manufacture, use, and storage of radioactive materials. The Price-Anderson Act (“PAA”) supports the nuclear services industry by offering broad indemnification to DOE contractors for liabilities arising out of nuclear incidents at DOE nuclear facilities. That indemnification protects DOE prime contractor,contractors, 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 Price-Anderson ActPAA was extended through 2025 by the Energy Policy Act of 2005.


The Price-Anderson Act’s

Under certain conditions, the PAA’s indemnification provisions generally domay not apply to our processing of radioactive waste at governmental facilities, and domay not apply to liabilities that we might incur while performing services as a contractor for the DOE and the nuclear energy industry. If an incident or evacuation is not covered under Price-Anderson ActPAA indemnification, we could be held liable for damages, regardless of fault, which could have an adverse effect on our results of operations and financial condition. If such indemnification authority is not applicable in the future, our business could be adversely affected if the owners and operators of new facilities fail to retain our services in the absence of commercial adequate insurance and indemnification.


We are engaged in highly competitive businesses and typically must bid against other competitors to obtain major contracts.


We are engaged in highly competitive business in which most of our government contracts and some of our commercial contracts are awarded through competitive bidding processes. We compete with national and regional firms with nuclear and/or hazardous waste services practices, as well as small or local contractors. Some of our competitors have greater financial and other resources 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 underrepresentedunder-represented minority contractors. Although we believe we have 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 also places downward pressure on our contract prices and profit margins. Intense competition is expected to continue for nuclear service contracts. If we are unable to meet these competitive challenges, we could lose market share and experience on overall reduction in our profits.


Our failure to maintain our safety record could have an adverse effect on our business.


Our safety record is critical to our reputation. In addition, many of our government and commercial customers require that we maintain certain specified safety record guidelines to be eligible to bid for contracts with these customers. Furthermore, contract terms may provide for automatic termination in the event that our safety record fails to adhere to agreed-upon guidelines during performance of the contract. As a result, our failure to maintain our safety record could have a material adverse effect on our business, financial condition and results of operations.


We continue to have material weaknesses in our Internal Control over Financial Reporting (“ICFR”).

During our evaluation of our ICFR, we noted that the monitoring of invoicing process controls and the corresponding transportation and disposal process controls at our Industrial Segment subsidiaries were ineffective and were not being applied consistently.  In addition, we noted that the monitoring of quote to invoicing control was ineffective at certain of our Nuclear Segment subsidiaries.  These deficiencies resulted in material weaknesses to our ICFR, and could result in sales being priced and invoiced at amounts which were not approved by the customer, or the appropriate level of management, and recognition of revenue in incorrect financial reporting period.  These deficiencies have resulted in our disclosure that our ICFR was ineffective as of the end of 2008 and 2007.  Although these material weaknesses did not result in a material adjustment to our quarterly or annual financial statements, if we are unable to remediate these material weaknesses, there is a reasonable possibility that a misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

We may be unable to utilize loss carryforwards in the future.


We

As of December 31, 2018, we have approximately $26,589,000$21,277,000 and $76,312,000 in net operating loss carryforwards for federal and state income tax purposes, respectively, which will expire from 2009 to 2028in various amounts starting in 2021 if not used against future federal and state income tax liabilities.liabilities, respectively. Our net loss carryforwards are subject to various limitations. Our ability to use the net loss carryforwards depends on whether we are able to generate sufficient income in the future years. Further, our net loss carryforwards have not been audited or approved by the Internal Revenue Service.


If any of our permits, other intangible assets, and tangible assets becomes impaired, we may be required to record significant charges to earnings.

Under accounting principles generally accepted in the United States (“U.S. GAAP”), we review our intangible and tangible assets for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. Our permits are tested for impairment at least annually. Factors that may be considered a change in circumstances, indicating that the carrying value of our permit, other intangible assets, and tangible assets may not be recoverable, include a decline in stock price and market capitalization, reduced future cash flow estimates, and slower growth rates in our industry. We may be required, in the future, to record impairment charges in our financial statements, in which any impairment of our permit, other intangible assets, and tangible assets is determined. Such impairment charges could negatively impact our results of operations.

We bear the risk of cost overruns in fixed-price contracts. We may experience reduced profits or, in some cases, losses under these contracts if costs increase above our estimates.

Our revenues may be earned under contracts that are fixed-price in nature. Fixed-price contracts expose us to a number of risks not inherent in cost-reimbursable contracts. Under fixed price and guaranteed maximum-price contracts, contract prices are established in part on cost and scheduling estimates which are based on a number of assumptions, including assumptions about future economic conditions, prices and availability of labor, equipment and materials, and other exigencies. If these estimates prove inaccurate, or if circumstances change such as unanticipated technical problems, difficulties in obtaining permits or approvals, changes in laws or labor conditions, weather delays, cost of raw materials or our suppliers’ or subcontractors’ inability to perform, cost overruns may occur and we could experience reduced profits or, in some cases, a loss for that project. Errors or ambiguities as to contract specifications can also lead to cost-overruns.

Adequate bonding is necessary for us to win certain types of new work and support facility closure requirements.

We are often required to provide performance bonds to customers under fixed-price contracts, primarily within our Services Segment. These surety instruments indemnify the customer if we fail to perform our obligations under the contract. If a bond is required for a particular project and we are unable to obtain it due to insufficient liquidity or other reasons, we may not be able to pursue that project. In addition, we provide bonds to support financial assurance in the event of facility closure pursuant to state requirements. We currently have a bonding facility but, the issuance of bonds under that facility is at the surety’s sole discretion. Moreover, due to events that affect the insurance and bonding markets generally, bonding may be more difficult to obtain in the future or may only be available at significant additional cost. There can be no assurance that bonds will continue to be available to us on reasonable terms. Our inability to obtain adequate bonding and, as a result, to bid on new work could have a material adverse effect on our business, financial condition and results of operations.

Failure to maintain effective internal control over financial reporting or failure to remediate a material weakness in internal control over financial reporting could have a material adverse effect on our business, operating results, and stock price.

Maintaining effective internal control over financial reporting is necessary for us to produce reliable financial reports and is important in helping to prevent financial fraud. If we are unable to maintain adequate internal controls, our business and operating results could be harmed. We are required to satisfy the requirements of Section 404(a) of Sarbanes Oxley and the related rules of the Commission, which require, among other things, management to assess annually the effectiveness of our internal control over financial reporting. 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, and our business, financial condition, and reputation could be harmed.

Systems failures, interruptions or breaches of security and other cyber security risks could have an adverse effect on our financial condition and results of operations.

We are subject to certain operational risks to our information systems. Because of efforts on the part of computer hackers and cyberterrorists to breach data security of companies, we face risk associated with potential failures to adequately protect critical corporate, customer and employee data. As part of our business, we develop and retain confidential data about us and our customers, including the U.S. government. We also rely on the services of a variety of vendors to meet our data processing and communications needs.

Despite our implemented security measures and established policies, we cannot be certain that all of our systems are entirely free from vulnerability to attack or other technological difficulties or failures or failures on the part of our employees to follow our established security measures and policies. Information security risks have increased significantly. Our technologies, systems, and networks may become the target of cyber-attacks, computer viruses, malicious code, or information security breaches that could result in the unauthorized release, gathering, monitoring, misuse, loss or destruction of our or our customers’ confidential, proprietary and other information and the disruption of our business operations. A security breach could adversely impact our customer relationships, reputation and operation and result in violations of applicable privacy and other laws, financial loss to us or to our customers or to our employees, and litigation exposure. While we maintain a system of internal controls and procedures, any breach, attack, or failure as discussed above could have a material adverse impact on our business, financial condition, and results of operations or liquidity.

There is also an increasing attention on the importance of cybersecurity relating to infrastructure. This creates the potential for future developments in regulations relating to cybersecurity that may adversely impact us, our customers and how we offer our services to our customers.

Risks Relating to our Intellectual Property


If we cannot maintain our governmental permits or cannot obtain required permits, we may not be able to continue or expand our operations.


We are a nuclear services and waste management company. Our business is subject to extensive, evolving, and increasingly stringent federal, state, and local environmental laws and regulations. Such federal, state, and local environmental laws and regulations govern our activities regarding the treatment, storage, recycling, disposal, and transportation of hazardous and non-hazardous waste and low-level radioactive waste. We must obtain and maintain permits or licenses to conduct these activities in compliance with such laws and regulations. Failure to obtain and maintain the required permits or licenses would have a material adverse effect on our operations and financial condition. If any of our facilities are unable to maintain currently held permits or licenses or obtain any additional permits or licenses which may be required to conduct its operations, we may not be able to continue those operations at these facilities, which could have a material adverse effect on us.


We believe our proprietary technology is important to us.


We believe that it is important that we maintain our proprietary technologies. There can be no assurance that the steps taken by us to protect our proprietary technologies will be adequate to prevent misappropriation of these technologies by third parties. Misappropriation of our proprietary technology could have an adverse effect on our operations and financial condition. Changes to current environmental laws and regulations also could limit the use of our proprietary technology.

Risks Relating to our Financial Position and Need for Financing


Failure to become profitable could have a material adverse effect on us.

We have not reported a profit for several years, and did not report a profit for the first quarter of 2019. Our main objective is to increase our revenues, returning the Company to profitability and to further evaluate various methods to increase our liquidity, when needed. If we are unable to return to profitability in the near future, this could have a material adverse effect on the Company.

Breach of financialany of the covenants in existingour credit facility could result in a default, triggering repayment of outstanding debt under the credit facility.


Our credit facility with our bank contains financial covenants. A breach of any of these covenants could result in a default under our credit facility triggering our lender to immediately require the repayment of all outstanding debt under our credit facility and terminate all commitments to extend further credit. InOur fixed charge coverage ratio fell below the past, noneminimum quarterly requirement under our credit facility in the fourth quarter of 2018; however, we have obtained a waiver for this non-compliance from our covenants have been restrictivelender. Additionally, our lender also has provided certain amendments to our operations.fixed charge coverage ratio requirements for 2019 which will enable us to meet our quarterly fixed charge coverage ratio requirements. If we fail to meet any of our loanfinancial covenants ingoing forward, including the futureminimum quarterly fixed charge coverage ratio requirement, and our lender does not further waive the non-compliance or further revise our covenant requirement so that we are in compliance, our lender could accelerateaccelerates the repaymentpayment of our borrowings under our credit facility. In thesuch event, that our lender accelerates the payment of our borrowing, we may not have sufficient liquidity to repay our debt under our credit facility and other indebtedness.


Our amount of debt and floating rates of interestborrowing availability under our credit facility could adversely affect our operations.


At December 31, 2008,2018, our aggregate consolidated debt was approximately $16,203,000. If our floating rates of interest experienced an upward increase of 1%, our debt service would increase by approximately $162,000 annually.$3,302,000. Our secured revolving credit facility (the “Credit Facility”Amended and Restated Revolving Credit, Term Loan and Security Agreement, dated October 31, 2011, as subsequently amended (“Revised Loan Agreement”) provides for an aggregatea total credit facility commitment of $25,000,000,approximately $18,100,000, consisting of an $18,000,000a $12,000,000 revolving line of credit and a term loan of $7,000,000.$6,100,000. The maximum we can borrow under the revolving part of the Credit Facilitycredit facility is based on a percentage of the amount of our eligible receivables outstanding at any one time reduced by outstanding standby letters of credit and any borrowing reduction that our lender may impose from time to time. As ofAt December 31, 2008,2018, we had borrowings under the revolving part of our Credit Facilitycredit facility of $6,500,000approximately $639,000 and borrowing availability of up to an additional $5,400,000 based on our outstanding eligible receivables.$2,368,000. A lack of positive operating results could have material adverse consequences on our ability to operate our business. Our ability to make principal and interest payments, or to refinance indebtedness, and borrow under our credit facility will depend on both our and our subsidiaries'subsidiaries’ future operating performance and cash flow. Prevailing economic conditions, interest rate levels, and financial, competitive, business, and other factors affect us. Many of these factors are beyond our control.

8

Our indebtedness could limit our financial and operating activities, and adversely affect our ability to incur additional debt to fund future needs.

As a result of our indebtedness, we could, among other things, be:

required to dedicate a substantial portion of our cash flow to the payment of principal and interest, thereby reducing the funds available for operations and future business opportunities;
make it more difficult for us to satisfy our obligations;
limit our ability to borrow additional money if needed for other purposes, including working capital, capital expenditures, debt service requirements, acquisitions and general corporate or other purposes, on satisfactory terms or at all;
limit our ability to adjust to changing economic, business and competitive conditions;
place us at a competitive disadvantage with competitors who may have less indebtedness or greater access to financing;
make us more vulnerable to an increase in interest rates, a downturn in our operating performance or a decline in general economic conditions; and
make us more susceptible to changes in credit ratings, which could impact our ability to obtain financing in the future and increase the cost of such financing.

Any of the foregoing could adversely impact our operating results, financial condition, and liquidity. Our ability to continue our operations depends on our ability to generate profitable operations or complete equity or debt financings to increase our capital.

Risks Relating to an Investment in our Common Stock


Issuance of substantial amounts of our common stockCommon Stock could depress our stock price.


Any sales of substantial amounts of our Common Stock in the public market could cause an adverse effect on the market price of our Common Stock and could impair our ability to raise capital through the sale of additional equity securities. The issuance of our Common Stock will result in the dilution in the percentage membership interest of our stockholders and the dilution in ownership value. As ofAt December 31, 2008,2018, we had 53,934,56011,936,573 shares of Common Stock outstanding.


In addition, as ofat December 31, 2008,2018, we had outstanding options to purchase 3,417,347616,000 shares of common stockour Common Stock at exercise prices ranging from $1.22$2.79 to $2.98$13.35 per share. Further, we have adopted aour preferred share rights plan, and if such is triggered, could result in the issuance of a substantial amount of our common stock.Common Stock. The existence of this quantity of rights to purchase our common stockCommon Stock under the preferred share rights plan could result in a significant dilution in the percentage ownership interest of our stockholders and the dilution in ownership value. Future sales of the shares issuable could also depress the market price of our common stock.

Such future issuancessales or conversions could also significantly reduce the percentage ownership and dilute the ownership value of our existing common stockholders.


Delaware law, certain of our charter provisions, our stock option plans, and outstanding warrants and our preferred stockPreferred Stock may inhibit a change of control under circumstances that could give you an opportunity to realize a premium over prevailing market prices.


We are a Delaware corporation governed, in part, by the provisions of Section 203 of the General Corporation Law of Delaware, an anti-takeover law. In general, Section 203 prohibits a Delaware public corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person 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 from, options and other awards under such plans upon a “change of control” (as defined in the respective plans). Such provisions may also have the result of discouraging acquisition of us.

9

We have authorized and unissued 17,648,09317,439,785 (which include shares issuable under outstanding options to purchase 3,417,347616,000 shares of our Common Stock) shares of our Common Stock and 2,000,000 shares of our Preferred Stock as of December 31, 20082018 (which includes 600,00050,000 shares of our Preferred Stock reserved for issuance under our preferrednew shareholder share rights plan)plan, discussed below). These unissued shares could be used by our management to make it more difficult for, and thereby discourage an attempt to acquire control of us.


Our Preferred Share Rights Plan may adversely affect our stockholders.

In May 2008, we

We have adopted a preferred shareshareholder rights plan (the “Rights Plan”), designed to ensure that all of our stockholders receive fair and equal treatment in the event of a proposed takeovermay discourage, delay or abusive tender offer.  However, the Rights Plan may also have the effect of deterring, delaying, or preventingprevent a change in control that might otherwise be in the best interests of our stockholders.


In general, under the terms of the Comany.

We have adopted a shareholder rights plan (“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 “Rights”Plan”) issued under the Rights Plan the number of shares 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 we are 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 purchase price of each Right is $13, subject to adjustment.

The Rights expire on May 2, 2018. 

Resale of shares offered by this prospectus could adversely affect the market price of our common stock and our ability to raise additional equity capital.

The sale, or availability for sale, of common stock in the public market pursuant to this prospectus may adversely affect the prevailing market price of our common stock and may impair our ability to raise additional capital by selling equity or equity-related securities. This prospectus includes 5,000,000 shares that will be available for resale (assuming the issuance from time to time of all of the common stock included in this offering).  The resale of a substantial number of shares of our common stock in the public market pursuant to this offering, and afterwards, could adversely affect the market price for our common stock and make it more difficult for you to sell our shares at times and prices that you feel are appropriate.

DESCRIPTION OF COMMON STOCK

Our certificate of incorporation authorizes us to issue up to 75,000,00030,000,000 shares of common stock, $0.001 par value. As of April 3, 2009,15, 2019, there were 54,019,32412,054,439 shares of our common stock issued and outstanding.

The holders of shares of our common stock are entitled to one vote per share on all matters to be voted on by stockholders. Common stock holders are entitled to receive dividends declared by the board of directors out of funds legally available for the payment of dividends, subject to the rights, if any, of preferred stock holders. However, we have never paid a dividend and we do not anticipate paying a dividend in the foreseeable future. Our current secured credit facility prohibits us from paying cash dividends on our common stock. Upon any liquidation, dissolution or winding up of our business, the holders of common stock are entitled to share equally in all assets available for distribution after payment of all liabilities and provision for liquidation preference of shares of preferred stock then outstanding. The holders of common stock have no preemptive rights and no rights to convert their common stock into any other securities. There are no redemption or sinking fund provisions applicable to our common stock. All outstanding shares of common stock are fully paid and nonassessable.

Each share of our common stock includes an attached Right arising under and subject to the terms described in, the Rights Agreement dated May 2, 2018 between us and Continental Stock Transfer & Trust Company, as rights agent. The terms of such Rights are summarized in “Rights Attaching to Our Common Stock” below.

The transfer agent and registrar for the common stock is Continental Stock Transfer & Trust Company, 17 Battery Place, One State Street Plaza, 30thFloor, 8, New York, New York 10004-1123.

RIGHTS ATTACHING TO OUR COMMON STOCK

On May 2, 2018, our Board of Directors declared a dividend distribution of one Right for each outstanding share of our common stock to our stockholders of record on May 12, 2018 (the “Record Date”). The Rights Agreement (as defined below) also contemplates the issuance of one Right for each share of common stock which is issued by the Company between the Record Date and the Distribution Date (or earlier redemption or termination of the Rights). The Rights are subject to the terms and conditions of a Shareholder Rights Agreement, a copy of which is attached as Exhibit 4.1 to our Form 8-A/12B Registration Statement filed on May 3, 2018 (“Rights Agreement”), and incorporated herein by reference, as well as a First Amendment to Shareholder Rights Agreement, dated May 2, 2019, a copy of which is attached as Exhibit 4.2 to our Current Report on Form 8-K filed on May 3, 2019, and incorporated herein by reference. A copy of the Rights Agreement is also available upon written request to us. Because the following is a summary, the description below of the Rights and the Rights Agreement necessarily omits certain terms, exceptions, or qualifications to the statements made therein. You are advised to review the entire Rights Agreement prior to making any investment decision.

Each Right entitles the registered holder to purchase from us one one-thousandth of a share of our Series B Junior Participating Preferred Stock, par value $.001 per share (the “Preferred Shares”) at a purchase price of $20.00 (the “Purchase Price”), subject to certain adjustments.

The Rights will not be exercisable until the earlier to occur of (i) the close of business on the 10th business day following a public announcement or filing that a person has, or a group of affiliated or associated persons or persons acting in concert have, become an “Acquiring Person,” which is defined as a person or group of affiliated or associated persons or persons acting in concert who, at any time after the date of the Rights Agreement, have acquired, or obtained the right to acquire, beneficial ownership of 15% or more of the Company’s outstanding shares of Common Stock, subject to certain exceptions, or (ii) the close of business on the 10th business day (or such other date as may be determined by action of the Board prior to such time as any person or group of affiliated or associated persons or persons acting in concert become an Acquiring Person) after the commencement of, or announcement of an intention to commence, a tender offer or exchange offer the consummation of which would result in any person becoming an Acquiring Person (the earlier of such dates being called the “Distribution Date”). Any existing stockholder or group that beneficially owns 15% or more of the Common Stock will be grandfathered at its current ownership level, but the Rights will become exercisable if at any time after the announcement of the Rights Agreement such stockholder or group increases its ownership of the Common Stock. Certain synthetic interests in securities created by derivative positions, whether or not such interests are considered to be ownership of the underlying common stock or are reportable for purposes of Regulation 13D of the Exchange Act, are treated as beneficial ownership of the number of shares of common stock equivalent to the economic exposure created by the derivative position, to the extent actual shares of the common stock are directly or indirectly held by counterparties to the derivatives contracts.

With respect to certificates representing shares of common stock outstanding as of the Record Date, until the Distribution Date, the Rights will be evidenced by such certificates for shares of common stock registered in the names of the holders thereof, and not by separate Rights Certificates, as described further below. With respect to book entry shares of common stock outstanding as of the Record Date, until the Distribution Date, the Rights will be evidenced by the balances indicated in the book entry account system of the transfer agent for the common stock. Until the earlier of the Distribution Date and the Expiration Date (as defined below), the transfer of any shares of common stock outstanding on the Record Date will also constitute the transfer of the Rights associated with such shares of common stock. As soon as practicable after the Distribution Date, separate certificates evidencing the Rights (“Right Certificates”) will be mailed to holders of record of the common stock as of the close of business on the Distribution Date, and such separate Right Certificates alone will evidence the Rights.

The Rights, which are not exercisable until the Distribution Date, will expire at the earliest to occur of (i) the close of business on May 2, 2021; (ii) the time at which the Rights are redeemed pursuant to the Rights Agreement; (iii) the time at which the Rights are exchanged pursuant to the Rights Agreement; or (iv) the time at which the Rights are terminated upon the closing of any merger or other acquisition transaction involving the Company pursuant to a merger or other acquisition agreement that has been approved by the Board prior to any person becoming an Acquiring Person (the earliest of (i), (ii), (iii) and (iv) is referred to as the “Expiration Date”).

Each share of Preferred Stock will be entitled to receive, when, as and if declared by the Board, a preferential per share quarterly dividend payment equal to the greater of (i) $1.00 per share or (ii) 1,000 times the aggregate per share amount of all cash dividends declared per share of common stock, and 1,000 times the aggregate per share amount (payable in kind) of all non-cash dividends or other distributions declared per share of common stock. Each share of Preferred Stock will entitle the holder thereof to 1,000 votes on all matters submitted to a vote of the stockholders of the Company. In the event of any merger, consolidation or other transaction in which shares of common stock are converted or exchanged, each share of Preferred Stock will be entitled to receive 1,000 times the amount received per share of common stock.

The Exercise Price payable, and the number of shares of Preferred Stock or other securities or property issuable, upon exercise of the Rights are subject to adjustment from time to time to prevent dilution (i) in the event of a stock dividend on, or a subdivision, combination or reclassification of the Preferred Stock, (ii) upon the grant to holders of the Preferred Stock of certain rights, options or warrants to subscribe for or purchase Preferred Stock or convertible securities at less than the then-current market price of the Preferred Stock, or (iii) upon the distribution to holders of the Preferred Stock of evidences of indebtedness or assets (excluding regular periodic cash dividends or dividends payable in Preferred Stock) or of subscription rights, options or warrants (other than those referred to above). The number of outstanding Rights and the number of one one-thousandths of a share of Preferred Stock issuable upon exercise of each Right are also subject to adjustment in the event of a stock split, reverse stock split, stock dividends and other similar transactions.

In the event that, after a person or a group of affiliated or associated persons or persons acting in concert have become an Acquiring Person, the Company is acquired in a merger or other business combination transaction, or 50% or more of the Company’s assets or earning power are sold, proper provision will be made so that each holder of a Right (other than Rights owned by an Acquiring Person) will thereafter have the right to receive, upon the exercise thereof at the then current exercise price of the Right, that number of shares of common stock of the acquiring company having a market value at the time of that transaction equal to two times the Exercise Price.

With certain exceptions, no adjustment in the Exercise Price will be required unless such adjustment would require an increase or decrease of at least one percent (1%) in the Exercise Price. No fractional shares of Preferred Stock will be issued (other than fractions which are integral multiples of one one-thousandth of a share of Preferred Stock, which may, at the election of the Company, be evidenced by depositary receipts) and, in lieu thereof, an adjustment in cash will be made based on the market price of the Preferred Stock on the trading day immediately prior to the date of exercise.

At any time after any person or group of affiliated or associated persons or persons acting in concert become an Acquiring Person and prior to the acquisition of beneficial ownership by such Acquiring Person of 50% or more of the outstanding shares of common stock, the Board, at its option, and in its sole discretion, may exchange each Right (other than Rights owned by such person or group of affiliated or associated persons or persons acting in concert which will have become void) in whole or in part, at an exchange ratio of one share of common stock per outstanding Right (subject to adjustment).

At any time before any person or group of affiliated or associated persons or persons acting in concert become an Acquiring Person, the Board may redeem the Rights in whole, but not in part, at a price of $0.001 per Right (subject to certain adjustments) (the “Redemption Price”). The redemption of the Rights may be made effective at such time, on such basis and with such conditions as the Board in its sole discretion may establish.

Immediately upon the action of the Board electing to redeem or exchange the Rights, the Company shall make announcement thereof, and upon such election, the right to exercise the Rights will terminate and the only right of the holders of Rights will be to receive the Redemption Price.

Subject to the terms of the Rights Agreement, in the event that any person or group of affiliated or associated persons acting in concert become an Acquiring Person by acquiring 15% or more of the Company’s common stock, except as otherwise provided in the Rights Agreement, each holder of a Right (other than the Acquiring Person) thereafter has the right to receive, upon exercise thereof and in accordance with the Rights Agreement, in lieu of a number of one one thousandth of a share of Preferred Stock, a number of shares of common stock of the Company equal to the result obtained by (A) multiplying the then current exercise price by the then number of one one-thousandth of a share of Preferred Stock for which a Right was or would have been exercisable and (B) dividing that product by 50% of the current market price of the Company’s common stock.

In addition, if a Qualifying Offer (as described below) is made, a sufficient number of shares of common stock have been tendered into the Qualifying Offer and not withdrawn to meet the Minimum Tender Condition (as defined below) and the Board has not redeemed the outstanding Rights or exempted such offer from the terms of the Rights Agreement or has not called a special meeting of stockholders for the purpose of voting on whether or not to exempt such Qualifying Offer from the terms of the Rights Agreement, in each case after 90 calendar days from the commencement of the Qualifying Offer (the “Board Evaluation Period”), the record holders of at least 15% of the outstanding shares of common stock may request, no later than 90 calendar days following the Board Evaluation Period, the Board to submit to a vote of stockholders at a special meeting of the stockholders of the Company (a “Special Meeting”) a resolution exempting such Qualifying Offer from the provisions of the Rights Agreement (the “Qualifying Offer Resolution”). If a Special Meeting is not held prior to 90 calendar days after such request or, if at the Special Meeting the holders of a majority of the shares of common stock outstanding (other than shares held by the offeror and its affiliated and associated persons) vote in favor of the Qualifying Offer Resolution, then the Board will exempt the Qualifying Offer from the provisions of the Rights Agreement or take such other action as may be necessary to prevent the Rights from interfering with the consummation of the Qualifying Offer.

A “Qualifying Offer” is an offer that is determined by the Board to have (among others) the following characteristics:

(i)an offer that has commenced within the meaning of Rule 14d-2(a) under the Exchange Act;
(ii)a fully-financed, all-cash tender offer, or an exchange offer offering shares of common stock of the offeror, or a combination thereof, in each such case for all of the outstanding shares of common stock at the same per-share consideration;
(iii)an offer that is conditioned on a minimum of at least a majority of (a) the shares of the common stock outstanding on a fully-diluted basis; and (b) the outstanding shares of the common stock not held by the offeror (or such offeror’s affiliates or associated persons) being tendered and not withdrawn as of the offer’s expiration date, which condition shall not be waivable (the “Minimum Tender Condition”);
(iv)an offer that is subject only to the Minimum Tender Condition and other customary terms and conditions, which conditions shall not include any financing, funding or similar conditions or any requirements with respect to the offeror or its agents being permitted any due diligence on the Company; and
(v)an offer pursuant to which the Company and its stockholders have received an irrevocable written commitment of the offeror that no amendments will be made to the offer to reduce the consideration being offered or to otherwise change the terms of the offer in a way that is adverse to a tendering stockholder.

Until a Right is exercised or exchanged, the holder thereof, as such, will have no rights as a stockholder of the Company, including, without limitation, the right to vote or to receive dividends.

The Board may amend or supplement the Rights Agreement without the approval of any holders of Rights, including, without limitation, in order to (a) cure any ambiguity, (b) correct inconsistent provisions, (c) alter time period provisions or (d) make additional changes to the Rights Agreement that the Board deems necessary or desirable. However, from and after any person or group of affiliated or associated persons or persons acting in concert become an Acquiring Person, the Rights Agreement may not be supplemented or amended in any manner that would adversely affect the interests of the holders of Rights.

The Rights Agreement, as well as the certificate of designations establishing the Series B Preferred Stock, are included as Exhibit 4.1 and Exhibit 3.1(i) to our Registration Statement on Form 8-A/12Bfiled with the SEC on May 3, 2018, and is incorporated herein by reference. The Rights Agreement was amended on May 2, 2019, solely to extend the Final Termination Date (as defined in the Rights Agreement) of the Rights Agreement from May 2, 2019 to May 2, 2021. TheFirst Amendment to Shareholder Rights Agreement is attached as Exhibit 4.2 to our Current Report on Form 8-K filed on May 3, 2019, and incorporated herein by reference.The foregoing description of the Rights does not purport to be complete and is qualified in its entirety by reference to the Rights Agreement and the First Amendment to Shareholder Rights Agreement.

Item 15. Indemnification of Officers and Directors


Section 145 of the Delaware Corporation Law provides that a corporation has the power to indemnify a director, officer, employee or agent of the corporation and certain other persons serving at the request of the corporation in related capacities against amounts paid and expenses incurred in connection with an action or proceeding to which he is or is threatened to be made a party by reason of such position, if such person shall have acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, in any criminal proceeding, if such person had no reasonable cause to believe his conduct was unlawful; provided that, no indemnification shall be made with respect to any matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the adjudicating court determines that, despite the adjudication of liability but in view of all the circumstance of the case, such person is fairly and reasonably entitled to indemnification.


Article EIGHTH of our Restated Certificate of Incorporation, as amended, provides as follows with respect to the indemnification of our officers and directors:


All persons who the Corporation is empowered to indemnify pursuant to the provisions of Section 145 of the General Corporation Law of the State of Delaware (or any similar provision or provisions of applicable law at the time in effect), shall be indemnified by the Corporation to the full extent permitted thereby. The foregoing right of indemnification shall not be deemed to be exclusive of any other rights to which those seeking indemnification may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors, or otherwise. No repeal or amendment of this Article EIGHTH shall adversely affect any rights of any person pursuant to this Article EIGHTH which existed at the time of such repeal or amendment with respect to acts or omissions occurring prior to such repeal or amendment.


Our Restated Certificate of Incorporation, as amended, provides that no director shall be personally liable to us or its stockholders for any monetary damages for breaches of fiduciary duty as a director, provided that this provision shall not eliminate or limit the liability of a director (i) for any breach of the director'sdirector’s duty of loyalty to us or our stockholders; (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (iii) under Section 174 of the General Corporation Law of the State of Delaware; or (iv) for any transaction from which the director derived an improper personal benefit.

(a) The undersigned registrant hereby undertakes:

(1)  To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(a)The undersigned registrant hereby undertakes:

(1)To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

 (i)To include any prospectus required by section 10(a)(3) of the Securities Act;

 (ii)To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.

 (iii)To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (1)(i), (1)(ii) and (1)(iii) do not apply if the registration statement is on Form S-3 or Form F-3, and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Sections 13 or 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.


(2)  That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)  To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4)That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

 (i)Each prospectus filed by the registrant pursuant to Rule 424(b)(3)shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and
II-2

 (ii)Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

II-2

(5)  That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities: The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(5)That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities: The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

 (i)Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

 (ii)Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

 (iii)The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

 (iv)Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b)The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(c)Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

II-3

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c)  Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable.  In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
