Non-GAAP Financial Measures

Disclosure in this prospectus of EBITDA and Adjusted EBITDA, which are “non-GAAP financial measures” as defined under the rules of the Securities and Exchange Commission (the “SEC”), are intended as supplemental measures of our performance that are not required by, or presented in accordance with, U.S. generally accepted accounting principles (“GAAP”). Neither EBITDA nor Adjusted EBITDA should be considered as an alternative to net income, income from continuing operations or any other performance measure derived in accordance with GAAP or as an alternative to cash flows from operating activities or any other liquidity measure derived in accordance with GAAP.

EBITDA represents net income before income taxes, interest income, interest expense and depreciation expense and amortization of other intangible assets. Adjusted EBITDA represents EBITDA before other non-cash charges not included in EBITDA such as amortization of stock compensation and other unusual non-recurring cash charges not associated with the ongoing operations of the Company. We believe these measures are frequently used by securities analysts, investors and other interested parties in the evaluation of high yield issuers, many of which present EBITDA and Adjusted EBITDA when reporting their results. Our presentation of EBITDA and Adjusted EBITDA should not be construed to imply that our future results will be unaffected by unusual or non-recurring items.

EBITDA and Adjusted EBITDA have limitations as analytical tools, and you should not consider either of these measures in isolation or as a substitute for analyses of our income or cash flows as reported under GAAP. Some of these limitations are:

We compensate for these limitations by relying primarily on our GAAP results and using EBITDA and Adjusted EBITDA only for supplemental purposes. Please see our financial statements and the related notes thereto included elsewhere in this prospectus. For a description of how EBITDA and Adjusted EBITDA are calculated from our net income and a reconciliation of our EBITDA and Adjusted EBITDA to net income, see the section entitled “Summary Historical Condensed Consolidated Financial Data” included elsewhere in this prospectus.

Industry and Market Data

The industry and market data contained in this prospectus are based either on our management’s own estimates or on independent industry publications, reports by market research firms or other published independent sources that we believe to be reliable. However, certain industry and market data is subject to change and cannot always be verified with complete certainty due to limits on the availability and reliability of raw data, the voluntary nature of the data gathering process and other limitations and uncertainties inherent in any statistical survey. Accordingly, you should be awareclear that the industry and market data contained in this prospectus, and estimates and beliefs based on such data, may not be reliable. Unless otherwise indicated, all information contained in this prospectus concerning the industry in general, including information regarding (1) our market position and market share within our industry, (2) historical data concerning sales and growth of sales in our industry and (3) expectations regarding future growth of sales in our industry, is based on management’s estimates using internal data, data from industry related publications, consumer research and marketing studies and other externally obtained data. While we are not aware of any misstatements regarding any industry or market data presented herein, industry and market data involve risks and uncertainties and are subject to change based on various factors, including those discussed under the caption “Risk Factors” in this prospectus.

Cautionary Statement Regarding Forward-Looking Statements

This prospectus includes forward-looking statements within the meaning of the U.S. federal securities laws in addition to historical information. These forward-looking statements are included throughout this prospectus, including in the sections entitled “Summary,” “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Business” and include, without limitation, statements regarding our industry, business strategy, plans, goals and expectations concerning our market position, future operations, margins, profitability, capital expenditures, liquidity and capital resources and other financial and operating information. When used in this discussion, the words “anticipate,” “assume,” “believe,” “budget,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “potential,” “predict,” “project,” “will,” “future” and similar terms and phrases are intended to identify forward-looking statements in this prospectus.

Forward-looking statements reflect our current expectations regarding future events, results or outcomes. These expectations may or may not be realized. Some of these expectations may be based upon assumptions, data or judgments that prove to be incorrect. In addition, our business and operations involve numerous risks and uncertainties, many of which are beyond our control, which could result in our expectations not being realized or otherwise materially affect our financial condition, results of operations and cash flows.

Actual events, results and outcomes may differ materially from our expectations due to a variety of factors. Although it is not possible to identify all of these factors, they include, among others, the following:

Any one of these factors or a combination of these factors could materially affect our future results of operations and could influence whether any forward-looking statements contained in this prospectus ultimately prove to be accurate. See also “Risk Factors” included elsewhere in this prospectus regarding the additional factors that have impacted or may impact our business and operations. Our forward-looking statements are not guarantees of future performance, and actual results and future performance may differ materially from those suggested in any forward-looking statements. We do not intend to update these statements unless we are required to do so under applicable securities laws.

RISK FACTORS

You should consider carefully the following information about these risks, together with the other information included in this prospectus, before deciding to tender your Old Notes in the exchange offer. Additional risks and uncertainties not presently known to us, or that we currently deem immaterial, may also materially adversely affect our business, financial condition or results of operations. We cannot assure you that any of the events discussed in the risk factors below, or other risks, will not occur. If they do, our business, financial condition and results of operations could be materially adversely affected. In such case, the trading price of the New Notes could decline, and you might lose all or part of your investment.

Risks Related to Exchange Offer

If you choose not to exchange your Old Notes in the exchange offer, the transfer restrictions currently applicable to your Old Notes will remain in force and the market price of your Old Notes could decline.

If you do not exchange your Old Notes for New Notes in the exchange offer, then you will continue to be subject to the transfer restrictions on the Old Notes as set forth in the offering memorandum distributed in connection with the private offering of the Old Notes. In general, the Old Notes may not be offered or sold unless they are registered or exempt from registration under the Securities Act and applicable state securities laws. We do not intend to register resales of the Old Notes under the Securities Act. You should refer to “Summary—Summary Description of the Exchange Offer” and “The Exchange Offer” for information about how to tender your Old Notes.

The tender of Old Notes under the exchange offer will reduce the principal amount of the Old Notes outstanding, which may have an adverse effect upon, and increase the volatility of, the market price of the Old Notes due to reduction in liquidity.

You must follow the exchange offer procedures carefully in order to receive the New Notes.

If you do not follow the procedures described herein, you will not receive any New Notes. The New Notes will be issued to you in exchange for Old Notes only after timely receipt by the exchange agent of:

If you want to tender your Old Notes in exchange for New Notes, you should allow sufficient time to ensure timely delivery. No one is under any obligation to give you notification of defects or irregularities with respect to tenders of Old Notes for exchange. For additional information, see the section captioned “The Exchange Offer” in this prospectus.

There are state securities law restrictions on the resale of the New Notes.

In order to comply with the securities laws of certain jurisdictions, the New Notes may not be offered or resold by any holder, unless they have been registered or qualified for sale in such jurisdictions or an exemption from registration or qualification is available and the requirements of such exemption have been satisfied. We currently do not intend to register or qualify the resale of the New Notes in any such jurisdictions. However, generally an exemption is available for sales to registered broker-dealers and certain institutional buyers. Other exemptions under applicable state securities laws also may be available.

Certain persons who participate in the exchange offer must deliver a prospectus in connection with resales of the New Notes.

Based on interpretations of the staff of the SEC contained inExxon Capital Holdings Corp., SEC no-action letter (April 13, 1988),Morgan Stanley & Co. Inc., SEC no-action letter (June 5, 1991) andShearman & Sterling, SEC no-action letter (July 2, 1983), we believe that you may offer for resale, resell or otherwise transfer the New Notes without compliance with the registration and prospectus delivery requirements of the Securities Act. However, in some instances described in this prospectus under “Plan of Distribution,” certain holders of New Notes will remain obligated to comply with the registration and prospectus delivery requirements of the Securities Act to transfer the New Notes. If such a holder transfers any New Notes without delivering a prospectus meeting the requirements of the Securities Act or without an applicable exemption from registration under the Securities Act, such a holder may incur liability under the Securities Act. We do not and will not assume, or indemnify such a holder against, this liability.

Risks Related to Our Business and Industry

The markets we serve are subject to cyclical demand, which could harm our business and make it difficult to project long-term performance.

Our operating results have been and may in the future be adversely affected by general economic conditions and the cyclical pattern of certain industries in which our customers and end users operate. Demand for our products and services depends in large part upon the level of capital and maintenance expenditures by many of our customers and end users, in particular those in the energy, chemical processing and power generation industries, or to firms that design and construct facilities for these industries. These customers’ expenditures historically have been cyclical in nature and vulnerable to economic downturns.

New facility construction projects have been a substantial source of recent revenue growth. Decreased capital and maintenance spending, or a decrease in new facility construction, by these customers could have a material adverse effect on the demand for our products and services and our business, financial condition and results of operations.

As a global business, we are exposed to economic, political and other risks in a number of countries, which could materially reduce our revenues, profitability or cash flows, or materially increase our liabilities. If we are unable to continue operating successfully in one or more foreign countries, it may have a material adverse effect on our business and financial condition.

For the fiscal year ended March 31, 2010, approximately 66% of our revenues were generated by our non-U.S. subsidiaries, and approximately 40% were generated outside North America. In addition, one of our key growth strategies is to continue to expand our foreign footprint in emerging and high growth markets around the world, although we may not be successful in expanding our international business.

Conducting business outside the U.S. is subject to additional risks, including the following:

One or more of these factors could prevent us from successfully expanding our presence in international markets and could also have a material adverse effect on our current international operations.

Our international operations also depend upon favorable trade relations between the U.S. and those foreign countries in which our customers and suppliers have operations. A protectionist trade environment in either the U.S. or those foreign countries in which we do business or sell products, such as a change in the current tariff structures, export compliance, government subsidies or other trade policies, may materially and adversely affect our ability to operate in foreign markets. In addition, because some of our international sales are to foreign governments and entities controlled by foreign governments (such as national corporations), we are subject to the political risks associated with foreign government projects.

We may not succeed in developing and implementing policies and strategies to counter the foregoing factors effectively in each location where we do business and the foregoing factors may cause a reduction in our revenues, profitability or cash flows, or cause an increase in our liabilities.

Our international operations and foreign subsidiaries are subject to a variety of complex and continually changing laws and regulations and, in particular, export control regulations.

Due to the international scope of our operations, we are subject to a complex system of laws and regulations, including regulations issued by the U.S. Department of Justice (“DOJ”), the Securities and Exchange Commission (“SEC”), the Internal Revenue Service (“IRS”), Customs and Border Protection, the Bureau of Industry and Security (“BIS”), the Office of Antiboycott Compliance (“OAC”) and the Office of Foreign Assets Control (“OFAC”), as well as the counterparts of these agencies in foreign countries. While we believe we are in material compliance with these regulations and maintain programs intended to achieve compliance, we may currently or may in the future be in violation of these regulations. In 2009, we entered into settlementssettlement agreements with BIS and OFAC, and are currently in the process of entering2010 we entered into a settlement agreement with OAC, in each case with respect to matters we voluntarily disclosed to such agencies. See “Business—Legal Proceedings” for more information on the pending OAC matter.

Any alleged or actual violations may subject us to government scrutiny, investigation and civil and criminal penalties and may limit our ability to export our products or provide services outside the U.S. Additionally, we cannot predict the nature, scope or effect of future regulatory requirements to which our international operations might be subject or the manner in which existing laws might be administered or interpreted.

In addition, our geographically widespread operations, coupled with our relatively smaller offices in many countries, make it more difficult to oversee and ensure that all our offices and employees comply with our internal policies and control procedures. We have in the past experienced employee theft, although the amounts involved have not been material, and we cannot assure you that we can ensure compliance with our internal control policies and procedures.

We operate in many different jurisdictions and we could be adversely affected by violations of the U.S. Foreign Corrupt Practices Act and similar foreign anti-corruption laws.

The U.S. Foreign Corrupt Practices Act (“FCPA”) and similar foreign anti-corruption laws generally prohibit companies and their intermediaries from making improper payments or providing anything of value to influence

foreign government officials for the purpose of obtaining or retaining business, or obtaining an unfair advantage. Recent years have seen a substantial increase in the global enforcement of anti-corruption laws, with more frequent voluntary self-disclosures by companies, aggressive investigations and enforcement proceedings by both the DOJ and the SEC resulting in record fines and penalties, increased enforcement activity by non-U.S. regulators, and increases in criminal and civil proceedings brought against companies and individuals. In addition, many of our customers and end users are involved in infrastructure construction and energy production, industries that are often subject to increased scrutiny by regulators. Our internal policies mandate compliance with these anti-corruption laws. We operate in many parts of the world that are recognized as having governmental corruption problems to some degree and where strict compliance with anti-corruption laws may conflict with local customs and practices. Our continued operation and expansion outside the U.S., including in developing countries, could increase the risk of such violations in the future. Despite our training and compliance programs, we cannot assure you that our internal control policies and procedures always will protect us from unauthorized reckless or criminal acts committed by our employees or agents. In the event that we believe or have reason to believe that our employees or agents have or may have violated applicable anti-corruption laws, including the FCPA, we may be required to investigate or have outside counsel investigate the relevant facts and circumstances, which can be expensive and require significant time and attention from senior management. Violations of these laws may result in severe criminal or civil sanctions, could disrupt our business, and result in a material adverse effect on our reputation, business and results of operations or financial condition.

Volatility in currency exchange rates may adversely affect our financial condition, results of operations or cash flows.

Our foreign subsidiaries generally sell their products and services in the local currency, but obtain a significant amount of their products from our facilities located in another country, primarily the U.S., Canada or Europe. Changes in the relevant exchange rates could adversely affect our margins on foreign sales of products. We also bid for certain foreign projects in U.S. dollars or euros. If the U.S. dollar or euro strengthens relative to the value of the local currency, we may be less competitive on those projects.

In order to meet our global cash management needs, we often transfer cash between the U.S. and foreign operations and sometimes between foreign entities. In addition, our debt service requirements are primarily in U.S. dollars and a substantial portion of our cash flow is generated in foreign currencies, and we will need to repatriate cash to the U.S. in order to meet our U.S. debt service obligations, including on the New Notes. These transfers of cash expose us to currency exchange rate risks, and significant changes in the value of the foreign currencies relative to the U.S. dollar could limit our ability to meet our debt obligations, including under the New Notes, and impair our financial condition.

Because our consolidated financial results are reported in U.S. dollars, and we generate a substantial amount of our sales and earnings in other currencies, the translation of those results into U.S. dollars can result in a significant decrease in the amount of those sales and earnings. In addition, fluctuations in currencies relative to the U.S. dollar may make it more difficult to perform period-to-period comparisons of our reported results of operations.

We may not be able to effectively manage our exchange rate and/or currency transaction risks. Volatility in currency exchange rates may decrease our revenues and profitability, adversely affect our liquidity and impair our financial condition. We have not historically entered into hedging instruments to manage our exchange rate risk.

A sustained downturn in the energy industry, due to oil and gas prices or otherwise, could decrease demand for some of our products and services and cause downward pressure on the prices we charge, which could materially and adversely affect our business, financial condition and results of operations.

A significant portion of our revenue for the fiscal year ended March 31, 2010 was generated by end-users in the upstream oil and gas markets. Accordingly, demand for a significant portion of our products and services

depends upon the level of capital expenditure by companies in the energy industry, which depends, in part, on energy prices. A sustained downturn in the capital expenditures of our customers, whether due to a decrease in the market price of oil and gas or otherwise, may decrease demand for our products and services and cause downward pressure on the prices we charge, which, in turn, could have a material adverse effect on our business, financial condition and results of operations.

A material disruption at any of our manufacturing facilities could adversely affect our results of operations.

If operations at any of our manufacturing facilities were to be disrupted as a result of significant equipment failures, natural disasters, power outages, fires, explosions, terrorism, adverse weather conditions, labor disputes or other reasons, we may be unable to fill customer orders and otherwise meet customer demand for our products, which could adversely affect our financial performance. Interruptions in production, in particular at our manufacturing facilities in San Marcos, Texas, or Calgary, Canada, could increase our costs and reduce our sales. Any interruption in production capability could require us to make substantial capital expenditures to fill customer orders, which could negatively affect our profitability and financial condition. We maintain property damage insurance which we believe to be adequate to provide for reconstruction of facilities and equipment, as well as business interruption insurance to mitigate losses resulting from any production interruption or shutdown caused by an insured loss. However, any recovery under our insurance policies may not offset the lost sales or increased costs that may be experienced during the disruption of operations, which could adversely affect our financial performance.

Our dependence on subcontractors could adversely affect our results of operations.

We rely on third party subcontractors as well as third party suppliers and manufacturers to complete our projects. To the extent that we cannot engage subcontractors or acquire supplies or materials, our ability to complete a project in a timely fashion or at a profit may be impaired. If the amount we are required to pay for these goods and services exceeds the amount we have estimated in bidding for fixed-price contracts, we could experience losses on these contracts. In addition, if a subcontractor or supplier is unable to deliver its services or materials according to the negotiated contract terms for any reason, including the deterioration of its financial condition or over-commitment of its resources, we may be required to purchase the services or materials from another source at a higher price. This may reduce the profit to be realized or result in a loss on a project for which the services or materials were needed.

Our future revenue depends in part on our ability to bid and win new contracts. Our failure to effectively obtain future contracts could adversely affect our profitability.

Our future revenue and overall results of operations require us to successfully bid on new contracts. For the fiscal year ended March 31, 2010, approximately 17% of our annual revenue consisted of designing, engineering, supplying and/or installing equipment for major projects (valued at over $5 million) pursuant to competitive bids. The number of such projects in any year fluctuates, and is dependent upon our ability to bid successfully for such projects. Contract proposals and negotiations are complex and frequently involve a lengthy bidding and selection process, which is affected by a number of factors, such as market conditions, financing arrangements and required governmental approvals. For example, a client may require us to provide a bond or letter of credit to protect the client should we fail to perform under the terms of the contract. If negative market conditions arise, or if we fail to secure adequate financial arrangements or required governmental approvals, we may not be able to pursue particular projects, which could adversely affect our profitability.

We may be unable to compete successfully in the highly competitive markets in which we operate.

We operate in competitive domestic and international markets and compete with highly competitive manufacturers and service providers, both domestically and on a global basis. A number of our direct and indirect competitors are major multinational corporations, some of which have substantially greater technical,

financial and marketing resources than us, and additional competitors may enter these markets. Our competitors may develop products that are superior to our products, develop methods of more efficiently and effectively providing products and services, or adapt more quickly than we do to new technologies or evolving customer requirements. Any increase in competition may cause us to lose market share or compel us to reduce prices to remain competitive, which could result in reduced sales and earnings.

A failure to deliver our backlog on time could affect our future sales and profitability and our relationships with our customers, and if we were to experience a material amount of modifications or cancellations of orders, our sales could be negatively impacted.

The ability to meet customer delivery schedules for our backlog is dependent on a number of factors including, but not limited to, access to the raw materials, an adequate and capable workforce, project engineering expertise for certain projects, sufficient manufacturing capacity and in some cases our reliance on subcontractors. A failure to deliver in accordance with our performance obligations may result in financial penalties and damage to existing customer relationships and our reputation, which could cause the loss of future business and could negatively impact our financial performance.

Our backlog is comprised of the portion of firm signed purchase agreements or other written contractual commitments received from customers that we have not recognized as revenue. The dollar amount of backlog as of June 30, 2010 was $78.3 million. Historically, we have experienced few order cancellations and the amount of cancellations of our orders has not been material compared to our total contract volume. Nonetheless, if we were to experience cancellations of or reductions in purchase orders, it would reduce our backlog and, consequently, our future sales and results of operations.

We are subject to project delays by our customers, which may adversely affect our operating results.

For the fiscal year ended March 31, 2010, approximately 17% of our revenue was derived from large customer projects valued at over $5 million. Customer project delays may occur, which in turn could delay or reduce our ability to realize value from our backlog and negatively impact the timing, or the amount of, revenue earned and the profitability of our business.

Due to the nature of our business, we may be liable for damages based on product liability claims. We are also exposed to potential indemnity claims from customers for losses due to our work or if our employees are injured performing services.

We face a risk of exposure to claims in the event that the failure, use or misuse of our products results, or is alleged to result, in death, bodily injury, property damage or economic loss. Although we maintain quality controls and procedures, we cannot be sure that our products will be free from defects. If any of our products prove to be defective, we may be required to replace the product. In addition, we may be required to recall or redesign such products, which could result in significant unexpected costs. Some of our products contain components manufactured by third parties, which may also have defects. In addition, if we are installing our products, we may be subject to claims that our installation caused damage or loss. Our products are often installed in our customers’ or end users’ complex and capital intensive facilities in inherently hazardous or dangerous industries, including energy, chemical processing and power generation, where the potential liability from risk of loss could be substantial. Although we currently maintain product liability coverage, which we believe is adequate for the continued operation of our business, we cannot be certain that this insurance coverage will continue to be available to us at a reasonable cost or, if available, will be adequate to cover any potential liabilities. With respect to components manufactured by third-party suppliers, the contractual indemnification that we seek from our third-party suppliers may be insufficient to cover claims made against us. In the event that we do not have adequate insurance or contractual indemnification, product liabilities could have a material adverse effect on our business, financial condition or results of operations.

Under our customer contracts, we often indemnify our customers from damages and losses they incur due to our work or services performed by us, as well as for losses our customers incur due to any injury or loss of life suffered by any of our employees or our subcontractor’s personnel occurring on our customer’s property. Many, but not all, of our customer contracts include provisions designed to limit our potential liability by excluding consequential damages and lost profits from our indemnity obligations. However, substantial indemnity claims may exceed the amount of insurance we maintain and could have a material adverse affect on our reputation, business, financial condition or results of operations.

MRO/UE revenue and Greenfield revenue represent our attempt to distinguish between recurring and new project revenues, which we cannot track with certainty and which are based on certain management estimates and assumptions.

Our revenue is generally derived from MRO/UE revenue and Greenfield revenue, with MRO/UE referring to recurring revenue attributable to maintenance, repair and operations and facility upgrades and expansions, and “Greenfield” referring to new facility construction projects. In our experience, we believe that $1 million in annual sales is an appropriate threshold for distinguishing between MRO/UE revenue and Greenfield revenue. We often sell our products to intermediaries or subcontract our services; accordingly, we have limited visibility into how our products or services may ultimately be used. Due to the nature of our sales, we can provide no assurance, however, that such measures may accurately reflect the sources of such revenue. Furthermore, our customers do not typically enter into long term forward maintenance contracts with us. In any given year, we may expect that certain of our smaller Greenfield projects may generate less than $1 million in annual sales, and certain of our larger plant expansions or upgrades may generate in excess of $1 million in annual sales. Therefore, MRO/UE revenue and Greenfield revenue are subjective and should not be unduly relied upon for purposes of distinguishing between our recurring and new project revenues.

We may lose money on fixed-price contracts, and we are exposed to liquidated damages risks in many of our customer contracts.

We often agree to provide products and services under fixed-price contracts; a significant portion of our turnkey sales are made pursuant to such fixed-price contracts. Under these contracts, we are typically responsible for all cost overruns, other than the amount of any cost overruns resulting from requested changes in order specifications. Our actual costs and any gross profit realized on these fixed-price contracts will often vary from the estimated costs on which these contracts were originally based. This may occur for various reasons, including errors in estimates or bidding, changes in availability and cost of labor and materials and unforeseen technical and logistical challenges. These variations and the risks inherent in our projects may result in reduced profitability or losses on projects. Depending on the size of a project, variations from estimated contract performance could have a material adverse impact on our operating results. In addition, many of our customer contracts, including fixed-price contracts, contain liquidated damages provisions in the event that we fail to perform our obligations thereunder in a timely manner or in accordance with the agreed terms, conditions and standards.

If we lose our senior management or other key employees, our business may be adversely affected.

Our ability to successfully operate and grow our global business and implement our strategies is largely dependent on the efforts, abilities and services of our senior management and other key employees. Our future success will also depend on, among other factors, our ability to attract and retain qualified personnel, such as engineers and other skilled labor, and in particular management and skilled employees for our foreign operations. Furthermore, two members of our senior management team are retiring from the Company later this year. Richard Hageman, Senior Vice President, Marketing and Technology, is retiring from the Company on August 31, 2010, and David Ralph, Senior Vice President, Finance, is retiring from the Company on September 30, 2010. The performance of their replacements may have an adverse effect on our overall profitability and market position.

We rely heavily on trade secrets to gain a competitive advantage in the market and the unenforceability of our nondisclosure agreements may adversely affect our operations.

The heat tracing industry is highly competitive and subject to the introduction of innovative techniques and services using new technologies. We require all employees to sign a nondisclosure agreement to protect our trade secrets, business strategy and other proprietary information. If the provisions of these agreements are found unenforceable in any jurisdiction within which we operate, the loss of key personnel may place us at a competitive disadvantage. Even where the provisions are enforceable, the confidentiality clauses may not provide adequate protection of our trade secrets and proprietary information in every jurisdiction.

We may be unable to prevent third parties from using our intellectual property rights, including trade secrets and know-how, without our authorization or from independently developing intellectual property that is the same as or similar to ours, particularly in those countries where the laws do not protect our intellectual property rights as fully as in the U.S. The unauthorized use of our trade secrets or know-how by third parties could reduce or eliminate any competitive advantage we have developed, cause us to lose sales or otherwise harm our business or increase our expenses as we attempt to enforce our rights.

Our intellectual property rights may not be successfully asserted in the future or may be invalidated, circumvented or challenged.

We have obtained and applied for some U.S. and, to a lesser extent, foreign trademark registrations and will continue to evaluate the registration of additional trademarks. We cannot guarantee that any of our pending applications will be approved. Moreover, even if the applications are approved, third parties may seek to oppose or otherwise challenge them. In addition, we rely on a number of significant unregistered trademarks, primarily abroad, but also in the U.S., in the day-to-day operation of our business. Without the protections afforded by registration, our ability to protect and use our trademarks may be limited and could negatively affect our business.

While we have patented some of our products and processes, we historically have not relied upon patents to protect our design or manufacturing processes or products, and our patents are not material to our operations or business. In addition, while we have not faced intellectual property infringement claims from others in recent years, in the event successful infringement claims are brought against us, particularly claims (under patents or otherwise) against our product design or manufacturing processes, such claims could have a material adverse affect on our business, financial condition or results of operation.

Our business strategy includes acquiring smaller, value-added companies and making investments that complement our existing business. These acquisitions and investments could be unsuccessful or consume significant resources, which could adversely affect our operating results.

Acquisitions and investments may involve cash expenditures, debt incurrence, operating losses and expenses that could have a material adverse effect on our financial condition and operating results. Acquisitions involve numerous other risks, including:

We have limited experience in acquiring or integrating other businesses or making investments or undertaking joint ventures with others. It may be difficult for us to complete transactions quickly and to integrate acquired operations efficiently into our current business operations. Any acquisitions or investments may ultimately harm our business or financial condition, as such acquisitions may not be successful and may ultimately result in impairment charges.

Additional liabilities related to taxes or potential tax adjustments could adversely impact our financial results, financial condition and cash flow.

We are subject to tax and related obligations in the jurisdictions in which we operate or do business, including state, local, federal and foreign taxes. The taxing rules of the various jurisdictions in which we operate or do business often are complex and subject to varying interpretations. Tax authorities may challenge tax positions that we take or historically have taken, and may assess taxes where we have not made tax filings or may audit the tax filings we have made and assess additional taxes, as they have done from time to time in the past. Some of these assessments may be substantial, and also may involve the imposition of substantial penalties and interest. In particular, in the years eligible for future audit, we consummated certain significant business transactions that we treated or intend to treat as not resulting in immediate gain for income tax purposes. Significant judgment is required in evaluating our tax positions and in establishing appropriate reserves. The resolutions of our tax positions are unpredictable. The payment of substantial additional taxes, penalties or interest resulting from any assessments could materially and adversely impact our results of operations, financial condition and cash flow.

Even though we expect to increase our repatriation of cash earned by our foreign subsidiaries to partially fund our interest payments in the U.S., we will leave a portion of such cash outside the U.S. as permanently reinvested earnings and profits. Accordingly, our estimated annual effective tax rate is based on partial, and not full, repatriation of cash earned by our foreign subsidiaries. If we have underestimated our need for repatriated cash, or our needs change, significant tax adjustments may result.

We have anticipated the need for a valuation reserve against deferred tax assets that are expected to arise this year as we repatriate earnings to partially fund our interest payments here in the U.S. We expect the deferred tax asset to arise from limitations on our ability to recover the foreign taxes paid on repatriated earnings. This calculation is complex and we may have underestimated or overestimated the need for a valuation reserve and significant tax adjustments may result.

We are subject to numerous environmental and health and safety laws and regulations, as well as potential environmental liabilities, which may require us to make substantial expenditures.

Our operations and properties are subject to a variety of federal, state, local and foreign environmental laws and regulations, including those governing the discharge of pollutants into the air or water, the management and disposal of hazardous substances or wastes, the cleanup of contaminated sites, and workplace health and safety. As an owner or operator of real property, or generator of waste, we could become subject to liability for environmental contamination, regardless of whether we caused such contamination. Certain environmental laws, including the Comprehensive Environmental Response, Compensation, and Liability Act, or CERCLA, impose joint and several liability for cleanup costs, without regard to fault, on persons who have disposed of or released hazardous substances into the environment. In addition, we could become liable to third parties for damages resulting from the disposal or release of hazardous substances into the environment. Some of our operations require environmental permits and controls to prevent and reduce air and water pollution, and these permits are subject to modification, renewal and revocation by issuing authorities. From time to time, we could be subject to requests for information, notices of violation, and/or investigations initiated by environmental regulatory agencies relating to our operations and properties, violations of environmental and health and safety laws can result in substantial penalties, civil and criminal sanctions, permit revocations, and facility shutdowns. Environmental and health and safety laws may change rapidly and have tended to become more stringent over time. As a result, we could incur costs for past, present, or future failure to comply with all environmental and health and safety laws and regulations. In addition, we could become subject to potential regulations concerning the emission of greenhouse gases, and while the effect of such future regulations cannot be determined at this time, they could require us to incur substantial costs in order to achieve and maintain compliance. In the ordinary course of business, we may be held responsible for any environmental damages we may cause to our customers’ premises.

The obligations associated with being a registered company will require significant resources and management attention.

As a result of filing the registration statement with the SEC in connection with this exchange offer and becoming a registrant, we will incur significant legal, accounting and other expenses that we did not previously incur. We will become subject to the reporting requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”). The Exchange Act requires that we file annual, quarterly and current reports with respect to our business and financial condition. The Sarbanes-Oxley Act requires, among other things, that we establish and maintain effective internal controls and procedures for financial reporting. Furthermore, the need to establish the corporate infrastructure demanded of a registrant may divert management’s attention from implementing our growth strategy, which could prevent us from improving our business, results of operations and financial condition. We have made, and will continue to make, changes to our internal controls and procedures for financial reporting and accounting systems to meet our reporting obligations as a registrant. However, the measures we take may not be sufficient to satisfy our obligations. In addition, we cannot predict or estimate the amount of additional costs we may incur in order to comply with these requirements.

Section 404 of the Sarbanes-Oxley Act requires annual management assessments of the effectiveness of our internal control over financial reporting, starting with the second annual report that we file with the SEC. In connection with the implementation of the necessary procedures and practices related to internal control over financial reporting, we may identify deficiencies that we may not be able to remediate in time to meet the deadline imposed by the Sarbanes-Oxley Act for compliance with the requirements of Section 404. If we fail to comply with Section 404, we could be subject to regulatory scrutiny and sanctions, our ability to obtain financing could be impaired and investors may lose confidence in the accuracy and completeness of our financial reports.

Risk Factors Relating to the New Notes and Our Other Indebtedness

Our substantial level of indebtedness could adversely affect our financial condition and prevent us from fulfilling our obligations under our Revolving Credit Facility or the New Notes.

We have substantial indebtedness. As of June 30, 2010, we had approximately $212.8 million of total debt outstanding, all of which was secured. Subject to restrictions in the Indenture governing the New Notes and in our Revolving Credit Facility, we may incur additional indebtedness. Our high level of indebtedness could have important consequences to you and significant effects on our business, including the following: it may be more difficult for us to satisfy our financial obligations, including with respect to the New Notes; our ability to obtain additional financing for working capital, capital expenditures, strategic acquisitions or general corporate purposes may be impaired; we must use a substantial portion of our cash flow from operations to pay interest on the New Notes and our other indebtedness, which will reduce the funds available to use for operations and other purposes; our ability to fund a change of control offer may be limited; our high level of indebtedness could place us at a competitive disadvantage compared to those of our competitors that may have proportionately less debt; our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate may be limited; and our high level of indebtedness may make us more vulnerable to economic downturns and adverse developments in our business.

We expect to obtain the funds to fulfill our working capital needs and to repay our indebtedness primarily from our operations and, in the case of our indebtedness, from refinancing thereof. Our ability to meet our working capital needs and make these payments thus depends on our future performance, which will be affected by financial, business, economic and other factors, many of which we cannot control. Our business may not generate sufficient cash flow from operations in the future and our currently anticipated growth in revenue and cash flow may not be realized, either or both of which could result in our being unable to repay indebtedness, including the New Notes, or to fund other liquidity needs. If we do not have enough funds, we may be required to refinance all or part of our then existing debt, sell assets or borrow more funds, which we may not be able to accomplish on terms acceptable to us, or at all. In addition, the terms of existing or future debt agreements may restrict us from pursuing any of these alternatives.

Despite our current indebtedness level, we and any of our existing or future subsidiaries may still be able to incur substantially more debt, which could exacerbate the risks associated with our substantial leverage.

We and any of our existing and future subsidiaries may be able to incur substantial additional indebtedness in the future. Although the terms of the Indenture and our Revolving Credit Facility will contain limitations on our ability to incur additional indebtedness, these restrictions are subject to a number of qualifications and exceptions. The total committed under the Revolving Credit Facility is $40.0 million, subject to borrowing base availability. If we incur any additional indebtedness that ranks equally with the New Notes, the holders of that additional debt will be entitled to share ratably with the holders of the New Notes in any proceeds distributed in connection with any insolvency, liquidation, reorganization, dissolution or other winding up of us, subject to any collateral securing the New Notes. If new debt is added to our or any of our existing and future subsidiaries’ current debt levels, the related risks that we now face could intensify. See “Description of Other Indebtedness.”

A significant portion of our business is conducted through foreign subsidiaries and our failure to generate sufficient cash flow from these subsidiaries, or otherwise repatriate or receive cash from these subsidiaries, could result in our inability to repay our indebtedness.

Our sales to customers located outside the U.S. are conducted primarily through subsidiaries organized under the laws of jurisdictions outside of the United States. For the fiscal year ended March 31, 2010, our foreign subsidiaries generated approximately 66% of our consolidated revenues. As of March 31, 2010, approximately 65% of our consolidated assets, based on book value, were held by foreign subsidiaries. Our ability to meet our debt service obligations with cash from foreign subsidiaries will depend upon the results of operations of these subsidiaries and may be subject to legal, contractual or other restrictions and other business considerations. Our foreign subsidiaries will not guarantee the New Notes. Our foreign subsidiaries may enter into financing arrangements that limit their ability to make loans or other payments to fund payments in respect of the New Notes. In particular, to the extent our foreign subsidiaries incur additional indebtedness to expand operations, the ability of our foreign subsidiaries to provide us cash may be limited. In addition, dividend and interest payments to us from our foreign subsidiaries may be subject to foreign withholding taxes, which would reduce the amount of funds we receive from such foreign subsidiaries. Dividends and other distributions from our foreign subsidiaries may also be subject to fluctuations in currency exchange rates and legal and other restrictions on repatriation, which could further reduce the amount of funds we receive from such foreign subsidiaries.

In general, when an entity in a foreign jurisdiction repatriates cash to the United States, the amount of such cash is treated as a dividend taxable at current U.S. tax rates. Accordingly, upon the distribution of cash to us from our foreign subsidiaries, we will be subject to U.S. income taxes. Although foreign tax credits may be available to reduce the amount of the additional tax liability, these credits may be limited based on the tax attributes of the Company. Therefore, to the extent that we must use cash generated in foreign jurisdictions to make principal or interest payments on the New Notes offered hereby, there may be a cost associated with repatriating the cash to the United States.

None of our foreign subsidiaries or any unrestricted subsidiaries are guarantors with respect to the New Notes, and therefore, any claims you may have in respect of the New Notes are structurally subordinated to the liabilities of those subsidiaries.

None of our foreign subsidiaries or any unrestricted subsidiaries guarantee the New Notes. If any of our foreign subsidiaries or unrestricted subsidiaries becomes insolvent, liquidates, reorganizes, dissolves or otherwise winds up, holders of its indebtedness and its trade creditors generally will be entitled to payment on their claims from the assets of such subsidiary before any of those assets would be made available to us. Consequently, your claims in respect of the New Notes will be structurally subordinated to all of the existing and future liabilities, including trade payables, of our foreign subsidiaries and any unrestricted subsidiaries. As of June 30, 2010, our foreign subsidiaries had $3.2 million in bank guarantees and $1.0 million in performance bonds outstanding. However, the Indenture, while restricting foreign subsidiaries’ indebtedness, nevertheless permits our foreign subsidiaries to incur indebtedness. See “Description of the New Notes.” We will not have any unrestricted subsidiaries as of

the date that this exchange offer is consummated. In addition, because the liens on the collateral securing the New Notes include pledges of a portion of the stock (or equivalent equity interest) of our foreign subsidiaries which are directly owned by our U.S. restricted subsidiaries, the validity of those pledges under local law, if applicable, and the ability of the holders of the New Notes to proceed against that collateral under local law, to the extent applicable, may be limited by such local law, which limitations may or may not affect such liens.

The Revolving Credit Facility and the Indenture impose certain operating and financial restrictions, which may prevent us from pursuing certain business opportunities and taking certain actions.

The Revolving Credit Facility and the Indenture impose, and future debt agreements may impose, operating and financial restrictions on us. These restrictions limit or prohibit, among other things, our ability to: incur additional indebtedness or issue disqualified capital stock unless certain financial tests are satisfied; pay dividends, redeem subordinated debt or make other restricted payments; make certain investments or acquisitions; issue stock of subsidiaries; grant or permit certain liens on our assets; enter into certain transactions with affiliates; merge, consolidate or transfer substantially all of our assets; incur dividend or other payment restrictions affecting certain of our subsidiaries; transfer or sell assets, including capital stock of our subsidiaries; and change the business we conduct.

These covenants could adversely affect our ability to finance our future operations or capital needs; obtain standby letters of credit, bank guarantees or performance bonds required to bid on or secure certain customer contracts; make strategic acquisitions or investments or enter into alliances; withstand a future downturn in our business or the economy in general; engage in business activities, including future opportunities, that may be in our interest; and plan for or react to market conditions or otherwise execute our business strategies. A breach of any of these covenants could result in a default in respect of the related indebtedness. Any default under the agreements covering our indebtedness that is not waived by the holders of such indebtedness and the remedies sought by the holders of such indebtedness, could make TII unable to pay the principal, premium, if any, and interest on the New Notes and substantially decrease the market value of the New Notes. If a default occurs, the holders of such indebtedness could elect to declare the indebtedness, together with accrued interest and other fees, to be immediately due and payable and proceed against any collateral securing that indebtedness. Acceleration of our other indebtedness could result in a default under the terms of the Indenture.

We may not be able to generate sufficient cash to service all of our indebtedness, including the New Notes, and may be forced to take other actions to satisfy our obligations under our debt agreements, which may not be successful.

Our ability to make scheduled payments on or to refinance our debt obligations depends on our financial condition and operating performance, which is subject to prevailing economic and competitive conditions and to certain financial, business and other factors beyond our control. Our business may not generate sufficient cash flow from operations in the future and our currently anticipated growth in revenue and cash flow may not be realized, either or both of which could result in our being unable to repay indebtedness, including the New Notes, or to fund other liquidity needs. Therefore, we may not be able to maintain a level of cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our indebtedness, including the borrowings under the Revolving Credit Facility and the New Notes offered hereby.

If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay investments and capital expenditures, or to sell assets, seek additional capital or restructure or refinance our indebtedness, including our indebtedness under our Revolving Credit Facility and the New Notes offered hereby. Our ability to restructure or refinance our debt will depend on the condition of the capital markets and our financial condition at such time. Any refinancing of our debt could be at higher interest rates and may require us to comply with more onerous covenants, which could further restrict our business operations. The terms of existing or future debt instruments, including our Revolving Credit Facility and the Indenture, may restrict us from adopting some of these alternatives. In addition, any failure to make payments of interest and

principal on our outstanding indebtedness on a timely basis would likely result in a reduction of our credit rating, which could harm our ability to incur additional indebtedness. These alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations.

The value of the collateral securing the New Notes may not be sufficient to pay the amounts owed under the New Notes. As a result, holders of the New Notes may not receive full payment on their New Notes following an event of default.

The proceeds of any sale of collateral securing the New Notes following an event of default with respect thereto may not be sufficient to satisfy, and may be substantially less than, amounts due on the New Notes. Furthermore, the liens on the collateral that secures the New Notes and any guarantee of the New Notes by our U.S. restricted subsidiaries will be contractually subordinated to liens on such collateral that secure our Revolving Credit Facility.

The value of the collateral in the event of liquidation will depend upon market and economic conditions, the availability of buyers and similar factors. The collateral does not include contracts, agreements, licenses and other rights that by their express terms prohibit the assignment thereof or the grant of a security interest therein. Some of these may be material to us and such exclusion could have a material adverse effect on the value of the collateral. The value of the collateral could be impaired in the future as a result of changing economic and market conditions, our failure to successfully implement our business strategy, competition and other factors. By its nature, some or all of the collateral may not have a readily ascertainable market value or may not be saleable or, if saleable, there may be delays in its liquidation. To the extent that liens, security interests and other rights granted to other parties (including the prior lien granted to the lenders under our Revolving Credit Facility) encumber assets owned by us, those parties have or may exercise rights and remedies with respect to the property subject to their liens that could adversely affect the value of that collateral and the ability of the trustee under the Indenture or the holders of the New Notes to realize or foreclose on that collateral. Consequently, we cannot assure investors in the New Notes that liquidating the collateral securing the New Notes would produce proceeds in an amount sufficient to pay any amounts due under the New Notes after also satisfying the obligations to pay any creditors with prior claims on the collateral. In addition, under the Intercreditor Agreement between the trustee and the lenders under our Revolving Credit Facility the right of the lenders to exercise remedies with respect to the collateral could delay liquidation of the collateral. Bankruptcy laws and other laws relating to foreclosure and sale also could substantially delay or prevent the ability of the trustee or any holder of the New Notes to obtain the benefit of any collateral securing the New Notes. Such delays could have a material adverse effect on the value of the collateral.

If the proceeds of any sale of collateral are not sufficient to repay all amounts due on the New Notes, the holders of the New Notes (to the extent not repaid from the proceeds of the sale of the collateral) would have only an unsecured claim against our remaining assets.

We will in most cases have control over the collateral, and the sale of particular assets by us could reduce the pool of assets securing the New Notes and the guarantees.

The collateral documents allow us to remain in possession of, retain exclusive control over, freely operate, and collect, invest and dispose of any income from, the collateral securing the New Notes and the guarantees. There are circumstances other than repayment or discharge of the New Notes under which the collateral securing the New Notes and guarantees will be released automatically, without your consent or the consent of the trustee.

Under various circumstances, collateral securing the New Notes and the guarantees will be released automatically, including: a sale, transfer or other disposal of such collateral in a transaction not prohibited under the Indenture; with respect to collateral held by a guarantor, upon the release of such guarantor from its guarantee; to the extent required in accordance with the Intercreditor Agreement; and to the extent we have defeased or satisfied and discharged the Indenture governing the New Notes.

In addition, the guarantee of a subsidiary guarantor will be automatically released to the extent it is released in connection with a sale of such subsidiary guarantor in a transaction not prohibited by the Indenture.

The Indenture also permits TII to designate one or more of its restricted subsidiaries that is a guarantor of the New Notes as an unrestricted subsidiary. If TII designates such a subsidiary guarantor as an unrestricted subsidiary for purposes of the Indenture, all of the liens on any collateral owned by such subsidiary or any of its subsidiaries and any guarantees of the New Notes by such subsidiary or any of its subsidiaries will be released under the Indenture. Designation of an unrestricted subsidiary will reduce the aggregate value of the collateral securing the New Notes to the extent that liens on the assets of the unrestricted subsidiary and its subsidiaries are released. In addition, the creditors of the unrestricted subsidiary and its subsidiaries will have a senior claim on the assets of such unrestricted subsidiary and its subsidiaries.

Rights of holders of New Notes in the collateral may be adversely affected by bankruptcy proceedings.

The right of the collateral agent for the New Notes to repossess and dispose of the collateral securing the New Notes upon acceleration is likely to be significantly impaired by federal bankruptcy law if bankruptcy proceedings are commenced by or against us prior to or possibly even after the collateral agent has repossessed and disposed of the collateral. Under the U.S. Bankruptcy Code, a secured creditor, such as the collateral agent for the New Notes, is prohibited from repossessing its security from a debtor in a bankruptcy case, or from disposing of security repossessed from a debtor, without bankruptcy court approval, which may not be given. Moreover, bankruptcy law permits the debtor to continue to retain and to use collateral, and the proceeds, products, rents or profits of the collateral, even though the debtor is in default under the applicable debt instruments; provided that the secured creditor is given “adequate protection.” The meaning of the term “adequate protection” may vary according to circumstances, but it is intended in general to protect the value of the secured creditor’s interest in the collateral as of the commencement of the bankruptcy case and may include cash payments or the granting of additional security, if and at such time as the bankruptcy court in its discretion determines, for any diminution in the value of the collateral as a result of the stay of repossession or disposition or any use of the collateral by the debtor during the pendency of the bankruptcy case. A bankruptcy court may determine that a secured creditor may not require compensation for a diminution in the value of its collateral if the value of the collateral exceeds the debt it secures. In view of the broad discretionary powers of a bankruptcy court, it is impossible to predict how long payments under the New Notes could be delayed following commencement of a bankruptcy case, whether or when the collateral agent would repossess or dispose of the collateral, or whether or to what extent holders of the New Notes would be compensated for any delay in payment or loss of value of the collateral through the requirements of “adequate protection.” Furthermore, in the event the bankruptcy court determines that the value of the collateral is not sufficient to repay all amounts due on the New Notes, the holders of the New Notes would have “under-secured claims” as to the difference. Federal bankruptcy laws do not permit the payment or accrual of interest, costs and attorneys’ fees for “under-secured claims” during the debtor’s bankruptcy case.

Any future pledge of collateral might be voidable in bankruptcy.

Any future pledge of collateral in favor of the collateral agent for the New Notes, including pursuant to security documents delivered after the date of the Indenture, might be voidable by the pledgor (as debtor in possession) or by its trustee in bankruptcy if certain events or circumstances exist or occur, including, among others, if the pledgor is insolvent at the time of the pledge, the pledge permits the holders of the New Notes to receive a greater recovery than if the pledge had not been given and a bankruptcy proceeding in respect of the pledgor is commenced within 90 days following the pledge, or, in certain circumstances, a longer period.

The collateral is subject to casualty risks.

The Indenture governing the New Notes and the related security documents require us and the guarantors to maintain adequate insurance or otherwise insure against risks to the extent customary with companies in the same or similar business operating in the same or similar locations. There are, however, certain losses, including losses

resulting from terrorist acts, that may be either uninsurable or not economically insurable, in whole or in part. As a result, we cannot assure you that the insurance proceeds will compensate us fully for our losses. If there is a total or partial loss of any of the collateral securing the New Notes, we cannot assure you that any insurance proceeds received by us will be sufficient to satisfy all the secured obligations, including the New Notes.

The rights of holders of New Notes to the collateral securing the New Notes may be adversely affected by the failure to perfect security interests in the collateral and other issues generally associated with the realization of security interests in collateral.

Applicable law requires that a security interest in certain tangible and intangible assets can only be properly perfected and its priority retained through certain actions undertaken by the secured party. The liens on the collateral may not be perfected with respect to the New Notes and the note guarantees if the trustee or the collateral agent is not able to or does not take the actions necessary to perfect any such liens, which the trustee and the collateral agent are not obligated to take. In addition, applicable law requires that certain property and rights acquired after the grant of a general security interest, such as real property, equipment subject to a certificate and certain proceeds, can be perfected only at the time at which such property and rights are acquired and identified. The trustee or the collateral agent for the New Notes may not monitor, or we may not inform the trustee or the collateral agent of, the future acquisition of property and rights that constitute collateral, and necessary action may not be taken to properly perfect the security interest in such after-acquired collateral. The trustee and the collateral agent for the New Notes have no obligation to monitor the acquisition of additional property or rights that constitute collateral or the perfection of any security interest in favor of the New Notes against third parties. A failure to do so may result in the loss of the security interest therein or the priority of the security interest in favor of the New Notes against third parties.

In addition, the security interest of the collateral agent for the New Notes will be subject to practical challenges generally associated with the realization of security interests in collateral. For example, the collateral agent may need to obtain the consent of third parties and make additional filings. If we are unable to obtain these consents or make these filings, the security interests may be invalid and the holders of the New Notes will not be entitled to the collateral or any recovery with respect to the collateral. The collateral agent may not be able to obtain any such consent. Further, the consents of any third parties may not be given when required to facilitate a foreclosure on such collateral. Accordingly, the collateral agent may not have the ability to foreclose upon those assets, and the value of the collateral may significantly decrease.

The pledge of the capital stock of our subsidiaries that will secure the New Notes will automatically be released from the lien on them and no longer constitute collateral when the pledge of such capital stock or such other securities would require the filing of separate financial statements with the SEC for that subsidiary.

The New Notes and the related guarantees will be secured by a pledge of the stock of some of our subsidiaries. Under the SEC regulations in effect as of the issue date of the New Notes, if the par value, book value as carried by us or market value (whichever is greatest) of the capital stock, other securities or similar items of a subsidiary pledged as part of the collateral is greater than or equal to 20% of the aggregate principal amount of the New Notes then outstanding, such a subsidiary would be required to provide separate financial statements to the SEC. Therefore, theThe Indenture and the collateral documents provide that any capital stock and other securities of our subsidiaries will automatically be excluded from the collateral to the extent thatwhen the pledge of such capital stock or other securities to securesecuring the New Notes would cause such companies to be required to filerequire the filing of separate financial statements with the SEC pursuant to Rule 3-16 of Regulation S-X (as in effect from time to time). We believe that the book value of the stock of Thermon Manufacturing Company, Thermon Canada Inc. and Thermon Europe B.V. may exceed the 20% threshold of Rule 3-16 of Regulation S-X, and we intend to work with the collateral agent of the New Notes to obtain the release of the pledged stock of these entities pursuant to the Indenture and the collateral documents.

As a result, holders of the New Notes could lose a portion or all of their security interest in the capital stock or other securities of those subsidiaries. It may be more difficult, costly and time-consuming for holders of the New Notes to foreclose on the assets of a subsidiary than to foreclose on its capital stock or other securities, so the proceeds realized upon any such foreclosure could be significantly less than those that would have been received upon any sale of the capital stock or other securities of such subsidiary. See “Description of the New Notes.”

The collateral securing the New Notes may be diluted under certain circumstances.

The collateral that will secure the New Notes also secures our obligations under the Revolving Credit Facility. This collateral may secure on apari passu basis additional senior indebtedness that we incur in the future, subject to restrictions on our ability to incur debt and liens under our Revolving Credit Facility and the Indenture. Your rights to the collateral would be diluted by any increase in the indebtedness secured on apari passu or priority basis by this collateral.

The liens on the collateral securing the New Notes and guarantees will be subordinated and your right to exercise remedies with respect to the collateral will be limited by the Intercreditor Agreement between the trustee, as collateral agent, and the lenders under our Revolving Credit Facility.

The liens on the collateral that secures the New Notes and any guarantees will be contractually subordinated to liens thereon that secure our Revolving Credit Facility. Consequently, the New Notes and the guarantees will be effectively subordinated to our Revolving Credit Facility to the extent of the value of such collateral. A number of the collateral agent’s rights and remedies with respect to the collateral, including the ability to cause the commencement of enforcement proceedings against the collateral and to control the conduct of such proceedings, will be significantly limited under the Intercreditor Agreement between the collateral agent for the holders of the New Notes and the lenders under our Revolving Credit Facility.

Federal and state fraudulent transfer laws may permit a court to void the New Notes and the guarantees, subordinate claims in respect of the New Notes and the guarantees and require noteholders to return payments received and, if that occurs, you may not receive any payments on the New Notes.

Federal and state fraudulent transfer and conveyance statutes may apply to the issuance of the New Notes and the incurrence of any guarantees of the New Notes. Under federal bankruptcy law and comparable provisions of state fraudulent transfer or conveyance laws, which may vary from state to state, the New Notes or any guarantee could be voided as a fraudulent transfer or conveyance if (1) we or any guarantor, as applicable, issued the New Notes or incurred the guarantees with the intent of hindering, delaying or defrauding creditors or (2) we or any guarantor, as applicable, received less than reasonably equivalent value or fair consideration in return for either issuing the New Notes or incurring the guarantees and, in the case of (2) only, one of the following is also true at the time thereof: we or any guarantor, as applicable, were insolvent or rendered insolvent by reason of the issuance of the New Notes or the incurrence of the guarantees; the issuance of the New Notes or the incurrence of the guarantees left us or any guarantor, as applicable, with an unreasonably small amount of capital to carry on its business; or we or any guarantor intended to, or believed that we or such guarantor would, incur debts beyond our or such guarantor’s ability to pay such debts as they mature.

A court would likely find that we or a guarantor did not receive reasonably equivalent value or fair consideration for the New Notes or such guarantee if we or such guarantor did not substantially benefit directly or indirectly from the issuance of the New Notes or the applicable guarantee. As a general matter, value is given for a transfer or an obligation if, in exchange for the transfer or obligation, property is transferred or an antecedent debt is secured or satisfied. A debtor will generally not be considered to have received value in connection with a debt offering if the debtor uses the proceeds of that offering to make a dividend payment or otherwise retire or redeem equity securities issued by the debtor. We cannot be certain as to the standards a court would use to determine whether or not we or such guarantor were solvent at the relevant time or, regardless of the standard that a court uses, that the issuance of the guarantee would not be further subordinated to our or any guarantor’s other debt.

Generally, however, an entity would be considered insolvent if, at the time it incurred indebtedness: the sum of its debts, including contingent liabilities, was greater than the fair saleable value of all its assets; or the present fair saleable value of its assets was less than the amount that would be required to pay its probable liability on its existing debts, including contingent liabilities, as they become absolute and mature; or it could not pay its debts as they become due.

If a court were to find that the issuance of the New Notes or the incurrence of the guarantees was a fraudulent transfer or conveyance, the court could void the payment obligations under the New Notes or such guarantees or further subordinate the New Notes or such guarantees to presently existing and future indebtedness of ours or of the related guarantor, or require the holders of the New Notes to repay any amounts received with respect to such guarantees. In the event of a finding that a fraudulent transfer or conveyance occurred, you may not receive any repayment on the New Notes. Further, the voidance of the New Notes could result in an event of default with respect to our and our subsidiaries’ other debt that could result in acceleration of such debt.

Although any guarantee entered into in connection with the issuance of the New Notes will contain a provision intended to limit that guarantor’s liability to the maximum amount that it could incur without causing the incurrence of obligations under its guarantee to be a fraudulent transfer, this provision may not be effective to protect such guarantee from being voided under fraudulent transfer law, or may substantially reduce that guarantor’s obligation.

The imposition of certain permitted liens will cause the assets on which such liens are imposed to be excluded from the collateral securing the New Notes and the guarantees. There are also certain other categories of property that are also excluded from the collateral.

The Indenture permits liens in favor of third parties to secure certain indebtedness, such as purchase money indebtedness and capital lease obligations, and assets subject to such liens will in certain circumstances be excluded from the collateral securing the New Notes and the guarantees. Our ability to incur purchase money indebtedness and capital lease obligations is subject to limitations as described in “Description of the New Notes.” In addition, certain categories of assets are excluded from the collateral securing the New Notes and the guarantees. Excluded assets include certain contracts, certain equipment and certain capital stock and other securities of our subsidiaries. See “Description of the New Notes.” If an event of default occurs and the New Notes are accelerated, the New Notes and the guarantees will rank equally with the holders of other unsubordinated and unsecured indebtedness of the relevant entity with respect to such excluded property and effectively subordinated to holders of obligations secured by a lien on such excluded property.

The credit ratings assigned to the Notes may not reflect all risks of an investment in the Notes.

The credit ratings assigned to the Notes reflect the rating agencies’ assessments of our ability to make payments on the Notes when due. Consequently, actual or anticipated changes in these credit ratings will generally affect the market value of the Notes. These credit ratings, however, may not reflect the potential impact of risks related to structure, market or other factors related to the value of the Notes.

Our ability to repurchase the New Notes upon a change of control may be limited.

Upon the occurrence of specific change of control events, we will be required to offer to repurchase all outstanding New Notes at 101% of the principal amount thereof, plus accrued and unpaid interest to the date of repurchase. The lenders under our Revolving Credit Facility may have the right to accelerate the indebtedness thereunder upon a change of control. Any of our future debt agreements may contain a similar provision. However, we may not have sufficient funds at the time of the change of control to make the required repurchase of New Notes or repayment of our other indebtedness. We may require additional financing from third parties to fund any such repurchase or repayment, and we cannot assure you that we would be able to obtain additional financing on satisfactory terms or at all. If we fail to repurchase any New Notes submitted in a change of control

offer, it would constitute an event of default under the Indenture which would, in turn, constitute an event of default under our Revolving Credit Facility and could constitute an event of default under our other indebtedness, even if the change of control itself would not cause a default. Important corporate events, such as takeovers, recapitalizations or similar transactions, may not constitute a change of control under the Indenture and thus not permit the holders of the New Notes to require us to repurchase or redeem the New Notes. See “Description of the New Notes—Repurchase at the Option of Holders—Change of Control.”

Noteholders may not be able to determine when a change of control giving rise to mandatory repurchase rights has occurred following a sale of “substantially all” of our assets and our restricted subsidiaries’ assets.

The definition of change of control in the Indenture governing the New Notes includes a phrase relating to the direct or indirect sale, conveyance, transfer, lease or other disposition of “all or substantially all” of our assets and our restricted subsidiaries’ assets. There is no precise established definition of the phrase “substantially all” under applicable law. Accordingly, the ability of a noteholder to require us to repurchase New Notes as a result of a sale, conveyance, transfer, lease or other disposition of less than all of our assets and our restricted subsidiaries’ assets to another individual, group or entity may be uncertain.

Because each guarantor’s liability under its guarantee may be reduced to zero, voided or released under certain circumstances, you may not receive any payments from some or all of the guarantors.

The guarantees of the New Notes are limited to the maximum amount that the guarantors are permitted to guarantee under applicable law. As a result, a guarantor’s liability under its guarantee could be reduced to zero, depending on the amount of other obligations of such guarantor. Further, under the circumstances discussed more fully above, a court under federal or state fraudulent conveyance and transfer statutes could void the obligations under a guarantee or further subordinate it to all other obligations of the guarantor. In addition, you will lose the benefit of a particular guarantee if it is released under certain circumstances described under “Description of the New Notes—New Note Guarantees.”

Variable rate indebtedness subjects us to interest rate risk, which could cause our debt service obligations to increase significantly.

Our borrowings under our Revolving Credit Facility are at variable rates of interest and expose us to interest rate risk. If interest rates increase, our debt service obligations on the variable rate indebtedness would increase even though the amount borrowed remained the same, and our net income would decrease. We may enter into interest rate swaps or other hedging instruments to reduce interest rate volatility. We cannot assure you, however, that we will be able to do so or that such swaps or hedging instruments will be effective.

There is currently no public market for the New Notes and an active trading market may not develop for the New Notes. The failure of a market to develop for the New Notes could affect the liquidity and value of the New Notes.

The New Notes will be a new issue of securities, and there is no existing market for the New Notes. An active market may not develop for the New Notes and there can be no assurance as to the liquidity of any market that may develop for the New Notes. If an active market does not develop, the market price and liquidity of the New Notes may be adversely affected.

The liquidity of the trading market, if any, and future trading prices of the New Notes will depend on many factors, including, among other things, the number of holders thereof, prevailing interest rates, our operating results, financial performance and prospects, the interest of securities dealers in making a market in the New Notes, the market for similar securities and the overall securities market, and may be adversely affected by unfavorable changes in these factors. Historically, the market for high-yield debt has been subject to disruptions that have caused substantial fluctuations in the prices of these securities. The market for the New Notes may be subject to similar disruptions. Any such disruptions may adversely affect the value of the New Notes.

We do not intend to apply for listing of the New Notes on any securities exchange or for quotation of the New Notes in any automated dealer quotation system.

CHS is able to make important decisions about our business and capital structure, and there may be situations in which the interests of CHS and our other Equity Sponsors and the holders of the New Notes will not be aligned.

Parent, a holding company, is TII’s sole shareholder, owning 100% of our outstanding capital stock. Parent, in turn, is indirectly wholly owned by TGH. A majority of the equity of TGH, our ultimate parent entity, is owned by certain investment funds associated with CHS. Therefore, subject to any agreements among our Equity Sponsors, CHS has control over our management and policies, such as the election of a majority of our directors, the appointment of new management and the approval of any other action requiring the approval of our shareholders, including any amendments to our articles of incorporation and mergers, acquisitions and consolidations with third parties and sales of all or substantially all of our assets. Consequently, circumstances may arise in which the interests of CHS could be in conflict with your interests as a holder of the New Notes, and CHS may pursue transactions that, in their judgment, could enhance their equity investment, even though the transaction might involve risks to holders of the New Notes. Furthermore, CHS and our other Equity Sponsors may, in the future, own businesses that directly or indirectly compete with us. CHS and our other Equity Sponsors may also pursue acquisition opportunities that may be complementary to our business, and as a result, those acquisition opportunities may not be available to us.

FORWARD-LOOKING STATEMENTS

This prospectus includes forward-looking statements within the meaning of the U.S. federal securities laws in addition to historical information. These forward-looking statements are included throughout this prospectus, including in the sections entitled “Summary,” “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Business” and include, without limitation, statements regarding our industry, business strategy, plans, goals and expectations concerning our market position, future operations, margins, profitability, capital expenditures, liquidity and capital resources and other financial and operating information. When used in this discussion, the words “anticipate,” “assume,” “believe,” “budget,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “potential,” “predict,” “project,” “will,” “future” and similar terms and phrases are intended to identify forward-looking statements in this prospectus.

Forward-looking statements reflect our current expectations regarding future events, results or outcomes. These expectations may or may not be realized. Some of these expectations may be based upon assumptions, data or judgments that prove to be incorrect. In addition, our business and operations involve numerous risks and uncertainties, many of which are beyond our control, which could result in our expectations not being realized or otherwise materially affect our financial condition, results of operations and cash flows.

Actual events, results and outcomes may differ materially from our expectations due to a variety of factors. Although it is not possible to identify all of these factors, they include, among others, the following:

Any one of these factors or a combination of these factors could materially affect our future results of operations and could influence whether any forward-looking statements contained in this prospectus ultimately prove to be accurate. See also “Risk Factors” included elsewhere in this prospectus regarding the additional factors that have impacted or may impact our business and operations. Our forward-looking statements are not guarantees of future performance, and actual results and future performance may differ materially from those suggested in any forward-looking statements. We do not intend to update these statements unless we are required to do so under applicable securities laws.

USE OF NON-GAAP FINANCIAL MEASURES

Disclosure in this prospectus of EBITDA and Adjusted EBITDA, which are “non-GAAP financial measures” as defined under the rules of the SEC, are intended as supplemental measures of our performance that are not required by, or presented in accordance with, GAAP. Neither EBITDA nor Adjusted EBITDA should be considered as an alternative to net income, income from continuing operations or any other performance measure derived in accordance with GAAP or as an alternative to cash flows from operating activities or any other liquidity measure derived in accordance with GAAP.

EBITDA represents net income before income taxes, interest income, interest expense and depreciation expense and amortization of other intangible assets. Adjusted EBITDA represents EBITDA before other non-cash charges not included in EBITDA such as amortization of stock compensation and other unusual non-recurring cash charges not associated with the ongoing operations of the Company. We believe these measures are frequently used by securities analysts, investors and other interested parties in the evaluation of high yield issuers, many of which present EBITDA and Adjusted EBITDA when reporting their results. Our presentation of EBITDA and Adjusted EBITDA should not be construed to imply that our future results will be unaffected by unusual or non-recurring items.

EBITDA and Adjusted EBITDA have limitations as analytical tools, and you should not consider either of these measures in isolation or as a substitute for analyses of our income or cash flows as reported under GAAP. Some of these limitations are:

We compensate for these limitations by relying primarily on our GAAP results and using EBITDA and Adjusted EBITDA only for supplemental purposes. Please see our financial statements and the related notes thereto included elsewhere in this prospectus. For a description of how EBITDA and Adjusted EBITDA are calculated from our net income and a reconciliation of our EBITDA and Adjusted EBITDA to net income, see the section entitled “Summary Historical Condensed Consolidated Financial Data” included elsewhere in this prospectus.

THE TRANSACTIONS

On March 26, 2010, Thermon Group, Inc. (“TGI”) entered into a stock purchase agreement with Thermon Holdings, LLC (“Seller”) and its wholly owned subsidiary, Thermon Holding Corp. (“Parent”), providing for the acquisition by TGI of all of the outstanding capital stock of Parent (the “Acquisition”). Upon the closing of the Acquisition on April 30, 2010, Parent became a wholly owned subsidiary of TGI, which in turn is a wholly owned subsidiary of Thermon Group Holdings, Inc. (“TGH”). TGH is owned by the Equity Investors. After accounting for subsequent working capital and other post-closing adjustments required by the stock purchase agreement, the purchase price is currently estimated to be $320.9 million, including the estimated remaining working capital adjustment, income tax adjustment and restricted cash payment obligations at June 30, 2010 of approximately $6.6 million. The initial purchase price was paid at closing by TGI issuing a demand note to Seller, which was repaid on the closing date with a portion of the proceeds from the cash investment by the Equity Investors and a portion of the proceeds of the sale of the Old Notes. Immediately following the closing of the Acquisition and the sale of the Old Notes, Thermon Finance, Inc. (“TFI”), which was solely owned by TGI, merged with and into Thermon Industries, Inc. (“TII”), a direct wholly owned subsidiary of Parent, and TII assumed all of TFI’s obligations under the Notes and the related indenture by operation of law. Parent and each direct and indirect U.S. restricted subsidiary of Parent (other than TII) guarantee TII’s obligations under the Notes.

The sources and uses of funds for the Transactions are shown in the table below.

The following chart shows a simplified overview of the corporate structure and the principal indebtedness after giving effect to the Transactions and identifies the issuer and guarantors of the Notes:

4.	The Notes are guaranteed by Parent and each direct and indirect U.S. restricted subsidiary of Parent (other than TII) and the Notes and the guarantees are secured by liens on substantially all of the assets of TII and the respective guarantors. See “Description of the New Notes.”

5.	TCI does not guarantee the Notes. TCI held approximately 41% of Parent’s consolidated total assets and generated approximately 26% of Parent’s consolidated revenues and 27% of Parent’s consolidated gross profits for the fiscal year ended March 31, 2010.

6.

None of our non-U.S. subsidiaries guarantee the Notes. The non-U.S. subsidiaries, including TCI, held approximately 65% of Parent’s consolidated total assets and generated approximately 66% of Parent’s consolidated revenues and 60% of Parent’s consolidated gross profits for fiscal year ended March 31, 2010.

USE OF PROCEEDS

We will not receive any proceeds from the exchange offer. Any Old Notes that are properly tendered and exchanged pursuant to the exchange offer will be retired and cancelled.

CAPITALIZATION

The following table sets forth our cash and cash equivalents and total capitalization as of June 30, 2010. The table below should be read in conjunction with “Use of Proceeds,” “Unaudited Pro Forma Condensed Consolidated Statements of Operations,” “Selected Historical Consolidated Financial Data,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated financial statements and accompanying notes included elsewhere in this prospectus.

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED STATEMENTS OF OPERATIONS

The following unaudited pro forma condensed consolidated statements of operations for the year ended March 31, 2010, the period from April 1, through April 30, 2010 (“Predecessor”), the period from May 1, through June 30, 2010 (“Successor”) and the three month ended June 30, 2009 (“Predecessor”) are based on our historical consolidated financial statements and give effect to the Transactions and this exchange offer as if they had occurred on April 1, 2009.

The unaudited pro forma condensed consolidated financial data includes unaudited pro forma adjustments that are directly attributable to the Transactions. In addition, with respect to the unaudited pro forma condensed consolidated statements of operations, the unaudited pro forma adjustments are expected to have a continuing impact on the consolidated results.

Pro forma adjustments were made to reflect the:

No pro forma adjustment was made to reflect the transaction expenses related to the Acquisition.

The Acquisition has been accounted for as a purchase in accordance with the applicable FASB Accounting Standards Codification (“ASC”) guidance. We have allocated the excess of the purchase price over the net assets acquired to intangible assets and goodwill. The preliminary allocation to intangible assets and goodwill is based on management’s best estimate of the fair value of the intangible assets (including trademarks, developed technology, customer list, backlog, certifications and non-compete agreements) and is consistent with the methodology applied during 2007 in connection with the acquisition of a controlling interest in the Company by affiliates of the Audax Private Equity Fund II, L.P.Group (the “Audax Transaction”). We have not allocated any of the excess purchase price to the acquired tangible assets or liabilities assumed, except for inventory, but rather utilized their current carrying value as we believe these carrying values approximate fair value, although we have not completed a third party valuation of the acquired assets or liabilities. The pro forma data presented will be revised based upon final calculations and the resolution of purchase price adjustments as additional information becomes available. The final allocation of the purchase price in the Acquisition will be determined at a later date and depends on a number of factors, including the final valuation of the tangible and identifiable intangible assets acquired and liabilities assumed in the Acquisition. An independent third-party appraiser will perform a valuation of these assets as of the closing date of the Acquisition, and upon a final valuation the purchase allocation will be adjusted. Such final adjustments, including changes to depreciation and amortization resulting from the allocation of purchase price to amortizable tangible and intangible assets, may be material. This valuation will be based on the net tangible and intangible assets and liabilities as of the closing date of the Acquisition.

We believe that the assumptions used to derive the unaudited pro forma condensed consolidated financial data are reasonable given the information available; however, such assumptions are subject to change and the effect of any such change could be material. The unaudited pro forma condensed consolidated financial data should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and the historical consolidated financial statements and related notes of Seller, included elsewhere in this prospectus. The unaudited pro forma condensed consolidated financial data is presented for informational purposes only and is not intended to represent or be indicative of the consolidated results of operations or financial position that we would have reported had the Transactions been completed as of the dates and for the periods presented, and should not be taken as representative of our consolidated results of operations or financial condition following the completion of the Transactions.
