Our Company
          We are a leading global designer, producer and marketer of a wide range of mechanical power transmission, or MPT, and motion control products serving customers in a diverse group of industries, including energy, general industrial, material handling, mining, transportation and turf and garden. Our product portfolio includes industrial clutches and brakes, enclosed gear drives, open gearing, couplings, engineered bearing assemblies, linear components and other related products. Our products are used in a wide variety of high-volume manufacturing processes, where the reliability and accuracy of our products are critical in both avoiding costly down time and enhancing the overall efficiency of manufacturing operations. Our products are also used in non-manufacturing applications where product quality and reliability are especially critical, such as clutches and brakes for elevators, and residential and commercial lawnmowers. For the nine months ended September 29, 2006, we had net sales of $347.5 million, net income of $10.7 million and EBITDA of $46.9 million.
          We market our products under well recognized and established brands, many of which have been in existence for over 50 years. We believe many of our brands, when taken together with our brands in the same product category, achieved the number one or number two position in terms of consolidated market share and brand awareness in their respective product categories. Our products are either incorporated into products sold by original equipment manufacturers, or OEMs, sold to end users directly or sold through industrial distributors.
          We are led by a highly experienced management team that has established a proven track record of execution, successfully completing and integrating major strategic acquisitions and delivering significant growth in both revenue and profits. We employ a comprehensive business process called the Altra Business System, or ABS, which focuses on eliminating inefficiencies from every business process to improve quality, delivery and cost.
Our Industry
          Based on industry data supplied by Penton Information Services, we estimate that industrial power transmission products generated sales in the United States of approximately $30.3 billion in 2005. These products are used to generate, transmit, control and transform mechanical energy. The industrial power transmission industry can be divided into three areas: MPT products; motors and generators; and

1


Table of Contents

adjustable speed drives. We compete primarily in the MPT area which, based on industry data, we estimate was a $15.7 billion market in the United States in 2005.
          The global MPT market is highly fragmented, with over 1,000 small manufacturers. While smaller companies tend to focus on regional niche markets with narrow product lines, larger companies that generate annual sales of over $100 million generally offer a much broader range of products and have global capabilities. The industry’s customer base is broadly diversified across many sectors of the economy and typically places a premium on factors such as quality, reliability, availability and design and application engineering support. We believe the most successful industry participants are those that leverage their distribution network, their products’ reputations for quality and reliability and their service and technical support capabilities to maintain attractive margins on products and gain market share.
Our Strengths
          Leading Market Shares and Brand Names. We believe we hold the number one or number two market position in key products across several of our core platforms. We are one of the leading manufacturers of industrial clutches and brakes in the world. We believe that over 50% of our sales are derived from products where we hold the number one or number two share and brand recognition, on a consolidated basis with our brands in the same product category, in the markets we serve.
          Large Installed Base Supporting Aftermarket Sales. With a history dating back to 1877 with the formation of Boston Gear, we believe we benefit from one of the largest installed customer bases in the industry which leads to significant aftermarket replacement demand creating a recurring revenue stream. For the nine months ended September 29, 2006, we estimate that approximately 43% of our revenues were derived from aftermarket sales.
          Diversified End-Markets. Our revenue base has balanced exposure across a diverse mix of end user industries, including energy, general industrial, material handling, mining, transportation and turf and garden, which helps mitigate the impact of business and economic cycles. In the first nine months of 2006, no single industry represented more than 10% of our total sales and in addition approximately 29% of our sales were from outside North America.
          Strong Relationships with Distributors and OEMs. We have over 700 direct OEM customers and enjoy established, long-term relationships with the leading MPT industrial distributors, critical factors that contribute to our high base of recurring aftermarket revenues. We sell our products through more than 3,000 distributor outlets worldwide.
          Experienced, High-Caliber Management Team. We are led by a highly experienced management team with over 425 years of cumulative industrial business experience and an average of 14 years with our companies. Our CEO, Michael Hurt, has over 39 years of experience in the MPT industry, while COO Carl Christenson has over 25 years of experience.
          The Altra Business System. We benefit from an established culture of lean management emphasizing quality, delivery and cost through the ABS. ABS is at the core of our performance-driven culture and drives both our strategic development and operational improvements. We estimate that in the period from January 1, 2005 through June 30, 2006, ABS has enabled us to achieve savings of over $5 million through various initiatives.
          Proven Product Development Capabilities. Our extensive application engineering know-how drives both new and repeat sales. Our broad portfolio of products, knowledge and expertise across various MPT applications allows us to provide our customers customized solutions to meet their specific needs.

Our Business Strategy
          We intend to continue to increase our sales through organic growth, expand our geographic reach and product offering through strategic acquisitions and improve our profitability through cost reduction initiatives. We seek to achieve these objectives through the following strategies:
  Leverage Our Sales and Distribution Network. We intend to continue to leverage our relationships with our distributors to gain shelf space, further integrate our recently acquired brands with our core brands and sell new products. We seek to capitalize on customer brand preference for our products to generate pull-through aftermarket demand from our distribution channel.
 
  Focus our Strategic Marketing on New Growth Opportunities. Through a systematic process that leverages our core brands and products, we seek to identify attractive markets and product niches, collect customer and market data, identify market drivers, tailor product and service solutions to specific market and customer requirements and deploy resources to gain market share and drive future sales growth.
 
  Accelerate New Product and Technology Development. We are highly focused on developing new products across our business in response to customer needs in various markets. In total, we expect new products developed by us during the past three years to generate approximately $40 million in revenues in 2006.
 
  Capitalize on Growth and Sourcing Opportunities in the Asia-Pacific Market. We intend to leverage our established sales offices in China, Taiwan and Singapore, as well as add representation in Japan and South Korea. We also intend to expand our manufacturing presence in Asia beyond our current plant in Shenzhen, China. During 2005, we sourced approximately 12% of our purchases from low-cost countries, resulting in average cost reductions of approximately 40% for these products. We intend to utilize our sourcing office in Shanghai to significantly increase our current level of low-cost country sourced purchases. We may also consider opportunities to outsource some of our production from North American and Western European locations to Asia.
 
  Continue to Improve Operational and Manufacturing Efficiencies through ABS. We believe we can continue to improve profitability through cost control, overhead rationalization, global process optimization, continued implementation of lean manufacturing techniques and strategic pricing initiatives. We have implemented these principles with our recent acquisitions of Hay Hall Holdings Limited, or Hay Hall, and Bear Linear LLC, or Bear Linear, and intend to apply such principles to future acquisitions.
 
  Pursue Strategic Acquisitions that Complement our Strong Platform. Management believes that there may be a number of attractive potential acquisition candidates in the future, in part due to the fragmented nature of the industry. We plan to continue our disciplined pursuit of strategic acquisitions to accelerate our growth, enhance our industry leadership and create value.
Risks Related to Our Strategies
          You should also consider the many risks we face that could mitigate our competitive strengths and limit our ability to implement our business strategies, including:
  if we are unable to address technological advances, or introduce new or improved products to meet customer needs, we may be unable to maintain or enhance our competitive positions with customers and distributors;
 
  if we are unable to continue to effectively implement our ABS operating plan, outsource parts and manufacturing from low cost countries, or introduce new cost effective manufacturing techniques, we may not continue to achieve cost savings;

Table of Contents

  our ability to improve or sustain operating margins as a result of cost-savings may be further impacted by cost increases in raw materials to the extent we are unable to offset any such cost increases with price increases on a timely basis;
 
  in the past, we have grown through acquisitions and we may be unable to identify attractive acquisition candidates, successfully integrate acquired operations or realize the intended benefits of our acquisitions; and
 
  as we expand our international operations we may be further subjected to risks not present in the U.S. markets such as foreign and U.S. government regulations and restrictions, tariffs and other trade barriers, foreign exchange risks and other risks related to political, economic and social instability.
          Investing in our common stock involves significant risks. Our ability to attain our objectives depends upon our success in addressing risks relating to our business and the industries we serve. You should carefully consider all of the information set forth in this prospectus, including the specific factors set forth under “Risk Factors,” before deciding whether to invest in our common stock.
Our Formation, Recent Acquisitions and Other Transactions
          The PTH Acquisition. On November 30, 2004, we acquired our original core business through the acquisition of Power Transmission Holding LLC, or PTH, from Warner Electric Holding, Inc., a wholly-owned subsidiary of Colfax Corporation, for $180.0 million in cash. PTH was organized in June 2004 to be the holding company for a group of companies comprising the power transmission business of Colfax Corporation. We refer to our acquisition of PTH as the “PTH Acquisition.”
          The Kilian Transactions. On October 22, 2004, The Kilian Company, or Kilian, a company formed at the direction of Genstar Capital LLC, or Genstar Capital, our principal equity sponsor, acquired Kilian Manufacturing Corporation from Timken U.S. Corporation for $8.8 million in cash and the assumption of $12.2 million of debt. At the completion of the PTH Acquisition, (i) all of the outstanding shares of Kilian capital stock were exchanged for approximately $8.8 million of shares of our capital stock and Kilian and its subsidiaries were transferred to our wholly owned subsidiary, Altra Industrial Motion, Inc., or Altra Industrial, and (ii) all outstanding debt of Kilian was retired with a portion of the proceeds of the sale of Altra Industrial’s 9.0% senior secured notes due 2011. See “Description of Indebtedness.”
          The Hay Hall Acquisition. On February 10, 2006, we acquired all of the outstanding share capital of Hay Hall Holdings Limited, or Hay Hall, for $50.3 million in cash. Hay Hall and its subsidiaries became our indirect wholly owned subsidiaries.
          In connection with our acquisition of Hay Hall, Altra Industrial issued £33.0 million of 11 1 / 4 % senior notes due 2013. See “Description of Indebtedness.”
          The Bear Linear Acquisition. On May 18, 2006, Altra Industrial acquired substantially all of the assets of Bear Linear for $5.0 million in cash. Approximately $3.5 million was paid at closing and the remaining $1.5 million is payable over the next two and a half years. Bear Linear manufactures high value-added linear actuators for mobile off-highway and industrial applications.

as if they had occurred as of the applicable date for balance sheet purposes and the first day of the applicable period for results of operations purposes.
(2)  The combined results were prepared by adding the results of Altra from December 1 to December 31, 2004 to those from our Predecessor for the 11 month period ending November 31, 2004. This presentation is not in accordance with GAAP. The primary differences between our Predecessor and the successor entity are the inclusion of Kilian in the successor and the successor’s book basis has been stepped up to fair value such that the successor has additional depreciation, amortization and financing costs. The results of Kilian are included in Altra for the period from December 1, 2004 through December 31, 2004. Management believes that this combined basis presentation provides useful information for our investors in the comparison to Predecessor trends and operating results. The combined results are not necessarily indicative of what our results of operations may have been if the PTH Acquisition and Kilian Transactions had been consummated earlier, nor should they be construed as being a representation of our future results of operations.
 
(3)  EBITDA is defined as earnings before interest, income taxes, depreciation and amortization. EBITDA is used by us as a performance measure. Management believes that EBITDA provides relevant information for our investors because it is useful for trending, analyzing and benchmarking the performance and value of our business. Management also believes that EBITDA is useful in assessing current performance compared with the historical performance of our Predecessor because significant line items within our income statements such as depreciation, amortization and interest expense were significantly impacted by the PTH Acquisition. Internally, EBITDA is used as a financial measure to assess the operating performance and is an important measure in our incentive compensation plans. EBITDA has important limitations, and should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP. For example, EBITDA does not reflect:
  cash expenditures, or future requirements, for capital expenditures or contractual commitments;
 
  changes in, or cash requirements for, working capital needs;
 
  the significant interest expense, or the cash requirements necessary to service interest or principal payments, on debts;
 
  tax distributions that would represent a reduction in cash available to us; and
 
  any cash requirements for assets being depreciated and amortized that may have to be replaced in the future.

          EBITDA is not a recognized measurement under GAAP, and when analyzing our operating performance, you should use EBITDA in addition to, and not as an alternative for, income (loss) from operations and net income (loss) (as determined in accordance with GAAP). Because not all companies use identical calculations, our presentation of EBITDA may not be comparable to similarly titled measures of other companies. The amounts shown for EBITDA also differ from the amounts calculated under similarly titled definitions in our debt instruments, which are further adjusted to reflect certain other cash and non-cash charges and are used to determine compliance with financial covenants and our ability to engage in certain activities, such as incurring additional debt and making certain restricted payments.
          To compensate for the limitations of EBITDA, we utilize several GAAP measures to review our performance. These GAAP measures include, but are not limited to, net income (loss), income (loss) from operations, cash provided by (used in) operations, cash provided by (used in) investing activities and cash provided by (used in) financing activities. These important GAAP measures allow management to, among other things, review and understand our use of cash from period to period, compare our operations with competitors on a consistent basis and understand the revenues and expenses matched to each other for the applicable reporting period. We believe that the use of these GAAP measures, supplemented by the use of EBITDA, allows us to have a greater understanding of our performance and allows us to adapt to changing trends and business opportunities.
(4)  Includes expenses relating to non-cash inventory step-up costs, management fees and transaction expenses associated with acquisitions which, if subtracted out, would result in a higher EBITDA. Inventory step-up costs accounted for $2.3 million, $1.7 million and $1.7 million, respectively, for the nine months ended September 29, 2006, the twelve months ended December 31, 2005 and the Combined Twelve Months Ended December 31, 2004. Management fees consisted of $0.8 million, $1.0 million and $0.1 million, respectively, for the nine months ended September 29, 2006, the twelve months ended December 31, 2005 and the Combined Twelve Months Ended December 31, 2004. Transaction fees and expenses associated with acquisitions accounted for $1.0 million and $4.4 million, respectively, for the nine months ended September 29, 2006 and the Combined Twelve Months Ended December 31, 2004.

RISK FACTORS
          Investing in our common stock involves a high degree of risk. You should carefully consider the following risk factors and all other information contained in this prospectus, including our financial statements and the related notes, before investing in our common stock. If any of the following risks materialize, our business, financial condition or results of operations could be materially harmed. In that case, the trading price of our common stock could decline significantly and you could lose some or all of your investment.
Risks Related to Our Business
We operate in the highly competitive mechanical power transmission industry and if we are not able to compete successfully our business may be significantly harmed.
          We operate in highly fragmented and very competitive markets in the MPT industry. Some of our competitors have achieved substantially more market penetration in certain of the markets in which we operate, such as helical gear drives and couplings, and some of our competitors are larger than us and have greater financial and other resources. With respect to certain of our products, we compete with divisions of our OEM customers. Competition in our business lines is based on a number of considerations, including quality, reliability, pricing, availability and design and application engineering support. Our customers increasingly demand a broad product range, and we must continue to develop our expertise in order to manufacture and market these products successfully. To remain competitive, we will need to invest regularly in manufacturing, customer service and support, marketing, sales, research and development and intellectual property protection. In the future we may not have sufficient resources to continue to make such investments and may not be able to maintain our competitive position within each of the markets we serve. We may have to adjust the prices of some of our products to stay competitive.
          Additionally, some of our larger, more sophisticated customers are attempting to reduce the number of vendors from which they purchase in order to increase their efficiency. If we are not selected to become one of these preferred providers, we may lose market share in some of the markets in which we compete.
          There is substantial and continuing pressure on major OEMs and larger distributors to reduce costs, including the cost of products purchased from outside suppliers such as us. As a result of cost pressures from our customers, our ability to compete depends in part on our ability to generate production cost savings and, in turn, find reliable, cost effective outside suppliers to source components or manufacture our products. If we are unable to generate sufficient cost savings in the future to offset price reductions, then our gross margin could be materially adversely affected.
Changes in general economic conditions or the cyclical nature of our markets could harm our operations and financial performance.
          Our financial performance depends, in large part, on conditions in the markets that we serve and on the U.S. and global economies in general. Some of the markets we serve are highly cyclical, such as the metals, mining, industrial equipment and energy markets. In addition, these markets may experience cyclical downturns. The present uncertain economic environment may result in significant quarter-to -quarter variability in our performance. Any sustained weakness in demand or continued downturn or uncertainty in the economy generally would further reduce our sales and profitability.
We rely on independent distributors and the loss of these distributors could adversely affect our business.
          In addition to our direct sales force and manufacturer sales representatives, we depend on the services of independent distributors to sell our products and provide service and aftermarket support to our customers. We support an extensive distribution network, with over 3,000 distributor locations worldwide. Rather than serving as passive conduits for delivery of product, our independent distributors are active participants in the overall competitive dynamics in the MPT industry. During the nine months ended

10


Table of Contents

September 29, 2006, approximately 35% of our net sales were generated through independent distributors. In particular, sales through our largest distributor accounted for approximately 8% of our net sales for the nine months ended September 29, 2006. Almost all of the distributors with whom we transact business offer competitive products and services to our customers. In addition, the distribution agreements we have are typically non-exclusive and cancelable by the distributor after a short notice period. The loss of any major distributor or a substantial number of smaller distributors or an increase in the distributors’ sales of our competitors’ products to our customers could materially reduce our sales and profits.
We must continue to invest in new technologies and manufacturing techniques; however, our ability to develop or adapt to changing technology and manufacturing techniques is uncertain and our failure to do so could place us at a competitive disadvantage.
          The successful implementation of our business strategy requires us to continuously invest in new technologies and manufacturing techniques to evolve our existing products and introduce new products to meet our customers’ needs in the industries we serve and want to serve. For example, motion control products offer more precise positioning and control compared to industrial clutches and brakes. If manufacturing processes are developed to make motion control products more price competitive and less complicated to operate, our customers may decrease their purchases of MPT products.
          Our products are characterized by performance and specification requirements that mandate a high degree of manufacturing and engineering expertise. If we fail to invest in improvements to our technology and manufacturing techniques to meet these requirements, our business could be at risk. We believe that our customers rigorously evaluate their suppliers on the basis of a number of factors, including:
  product quality and availability;
 
  price competitiveness;
 
  technical expertise and development capability;
 
  reliability and timeliness of delivery;
 
  product design capability;
 
  manufacturing expertise; and
 
  sales support and customer service.
          Our success depends on our ability to invest in new technologies and manufacturing techniques to continue to meet our customers’ changing demands with respect to the above factors. We may not be able to make required capital expenditures and, even if we do so, we may be unsuccessful in addressing technological advances or introducing new products necessary to remain competitive within our markets. Furthermore, our own technological developments may not be able to produce a sustainable competitive advantage.
Our operations are subject to international risks that could affect our operating results.
          Our net sales outside North America represented approximately 29% of our total net sales for the nine months ended September 29, 2006 and we expect these sales to increase in the future due to the Hay Hall Acquisition. In addition, we sell products to domestic customers for use in their products sold overseas. Our business is subject to risks associated with doing business internationally, and our future results could be materially adversely affected by a variety of factors, including:
  fluctuations in currency exchange rates;
 
  exchange rate controls;
 
  tariffs or other trade protection measures and import or export licensing requirements;

11


Table of Contents

  potentially negative consequences from changes in tax laws;
 
  interest rates;
 
  unexpected changes in regulatory requirements;
 
  changes in foreign intellectual property law;
 
  differing labor regulations;
 
  requirements relating to withholding taxes on remittances and other payments by subsidiaries;
 
  restrictions on our ability to own or operate subsidiaries, make investments or acquire new businesses in various jurisdictions;
 
  potential political instability and the actions of foreign governments; and
 
  restrictions on our ability to repatriate dividends from our subsidiaries.
          As we continue to expand our business globally, our success will depend, in large part, on our ability to anticipate and effectively manage these and other risks associated with our international operations. However, any of these factors could materially adversely affect our international operations and, consequently, our operating results.
Our operations depend on production facilities throughout the world, many of which are located outside the United States and are subject to increased risks of disrupted production causing delays in shipments and loss of customers and revenue.
          We operate businesses with manufacturing facilities worldwide, many of which are located outside the United States including in Canada, China, France, Germany, England and Scotland. Serving a global customer base requires that we place more production in emerging markets to capitalize on market opportunities and cost efficiencies. Our international production facilities and operations could be disrupted by a natural disaster, labor strike, war, political unrest, terrorist activity or public health concerns, particularly in emerging countries that are not well-equipped to handle such occurrences.
Material weaknesses in our internal controls over financial reporting have been identified which could result in a decrease in the value of our common stock.
          In connection with their audit of our fiscal 2005 financial statements, our independent auditors expressed concerns that as of the date of their opinion we were unable to report accurate financial information in a timely manner due to resource limitations of our corporate financial staffing and the impact of this limitation on our ability to timely report our financial information. Based upon the timely financial reporting required of a public company, the outside auditors informed senior management and the Audit Committee of our Board of Directors that they believe this is a material weakness in our internal controls. We have actively taken steps to address this material weakness. These steps include the recent hiring of a Director of Internal Audit and Securities and Exchange Commission Manager, or SEC Manager and our prior hiring of a Corporate Controller, Director of Taxation and a Corporate Accountant. We believe that with the addition of these resources we should be able to deliver financial information on a timely basis.
          However, we cannot assure you that our efforts to correct this identified material weakness will be successful or that we will not have other weaknesses in the future. If we fail to correct the existing material weaknesses or have material weaknesses in the future, it could affect the financial results that we report or create a perception that those financial results do not accurately state our financial condition or results of operations. Either of those events could have an adverse effect on the value of our common stock.

If we are unable to complete our assessment as to the adequacy of our internal controls over financial reporting as of December 31, 2007 as required by Section 404 of the Sarbanes-Oxley Act of 2002, or if material weaknesses are identified and reported, investors could lose confidence in the reliability of our financial statements, which could result in a decrease in the value of your investment.
          As directed by Section 404 of the Sarbanes-Oxley Act of 2002, the Securities and Exchange Commission, or SEC, adopted rules requiring public companies to include in their annual reports on Form  10-K a report of management on the company’s internal controls over financial reporting, including management’s assessment of the effectiveness of the company’s internal controls over financial reporting as of the company’s fiscal year end. In addition, the accounting firm auditing a public company’s financial statements must also attest to, and report on, management’s assessment of the effectiveness of the company’s internal controls over financial reporting as well as the operating effectiveness of the company’s internal controls. While we will expend significant resources in developing the necessary documentation and testing procedures, fiscal 2007 will be the first year for which we must complete the assessment and undergo the attestation process required by Section 404 and there is a risk that we may not comply with all of its requirements, considering the material weakness related to our financial staffing. If we do not timely complete our assessment or if our internal controls are not designed or operating effectively as required by Section 404, our independent auditors may either disclaim an opinion as it relates to management’s assessment of the effectiveness of its internal controls or may issue a qualified opinion on the effectiveness of our internal controls. It is possible that material weaknesses in our internal controls could be found. If we are unable to remediate any material weaknesses by December 31, 2007, our independent auditors would be required to issue an adverse opinion on our internal controls. If our independent auditors disclaim an opinion as to the effectiveness of our internal controls or if they render an adverse opinion due to material weaknesses in our internal controls, then investors may lose confidence in the reliability of our financial statements, which could cause the market price of our common stock to decline and make it more difficult for us to raise capital in the future.
We rely on estimated forecasts of our OEM customers’ needs, and inaccuracies in such forecasts could materially adversely affect our business.
          We generally sell our products pursuant to individual purchase orders instead of under long-term purchase commitments. Therefore, we rely on estimated demand forecasts, based upon input from our customers, to determine how much material to purchase and product to manufacture. Because our sales are based on purchase orders, our customers may cancel, delay or otherwise modify their purchase commitments with little or no consequence to them and with little or no notice to us. For these reasons, we generally have limited visibility regarding our customers’ actual product needs. The quantities or timing required by our customers for our products could vary significantly. Whether in response to changes affecting the industry or a customer’s specific business pressures, any cancellation, delay or other modification in our customers’ orders could significantly reduce our revenue, impact our working capital, cause our operating results to fluctuate from period to period and make it more difficult for us to predict our revenue. In the event of a cancellation or reduction of an order, we may not have enough time to reduce operating expenses to minimize the effect of the lost revenue on our business and we may purchase too much inventory and spend more capital than expected.
The materials used to produce our products are subject to price fluctuations that could increase costs of production and adversely affect our profitability.
          The materials used to produce our products, especially copper and steel, are sourced on a global or regional basis and the prices of those materials are susceptible to price fluctuations due to supply and demand trends, transportation costs, government regulations and tariffs, changes in currency exchange rates, price controls, the economic climate and other unforeseen circumstances. As of the nine months ended September 29, 2006, approximately 54% of our cost of goods sold consisted of the purchase of raw materials required for our manufacturing processes. From the first quarter of 2004 to the first quarter of 2006, the average price of copper and steel has increased approximately 84% and 46%, respectively. If we

13


Table of Contents

are unable to continue to pass a substantial portion of such price increases on to our customers on a timely basis, our future profitability may be materially and adversely affected. In addition, passing through these costs to our customers may also limit our ability to increase our prices in the future.
We face potential product liability claims relating to products we manufacture or distribute, which could result in our having to expend significant time and expense to defend these claims and to pay material claims or settlement amounts.
          We face a business risk of exposure to product liability claims in the event that the use of our products is alleged to have resulted in injury or other adverse effects. We currently have several product liability claims against us with respect to our products. Although we currently maintain product liability insurance coverage, we may not be able to obtain such insurance on acceptable terms in the future, if at all, or obtain insurance that will provide adequate coverage against potential claims. Product liability claims can be expensive to defend and can divert the attention of management and other personnel for long periods of time, regardless of the ultimate outcome. An unsuccessful product liability defense could have a material adverse effect on our business, financial condition, results of operations or our ability to make payments under our debt obligations when due. In addition, we believe our business depends on the strong brand reputation we have developed. In the event that our reputation is damaged, we may face difficulty in maintaining our pricing positions with respect to some of our products, which would reduce our sales and profitability.
We may be subject to work stoppages at our facilities, or our customers may be subjected to work stoppages, which could seriously impact our operations and the profitability of our business.
          As of September 29, 2006, we had approximately 2,600 full time employees, of whom approximately 43% were employed abroad. Approximately 300 of our North American employees and 45 of our employees in Scotland are represented by labor unions. In addition, our employees in Europe are generally represented by local and national social works councils that hold discussions with employer industry associations regarding wage and work issues every two to three years. Our European facilities, particularly those in France and Germany, may participate in such discussions and be subject to any agreements reached with employees.
          Our four U.S. collective bargaining agreements will expire on August 10, 2007, September 19, 2007, June 2, 2008 and February 1, 2009. Our union agreement in Scotland expires on March 31, 2007. We may be unable to renew these agreements on terms that are satisfactory to us, if at all. In addition, two of our four U.S. collective bargaining agreements contain provisions for additional, potentially significant, lump-sum severance payments to all employees covered by the agreements who are terminated as the result of a plant closing.
          If our unionized workers or those represented by a works council were to engage in a strike, work stoppage or other slowdown in the future, we could experience a significant disruption of our operations. Such disruption could interfere with our ability to deliver products on a timely basis and could have other negative effects, including decreased productivity and increased labor costs. In addition, if a greater percentage of our work force becomes unionized, our business and financial results could be materially adversely affected. Many of our direct and indirect customers have unionized work forces. Strikes, work stoppages or slowdowns experienced by these customers or their suppliers could result in slowdowns or closures of assembly plants where our products are used and could cause cancellation of purchase orders with us or otherwise result in reduced revenues from these customers.
Changes in employment laws could increase our costs and may adversely affect our business.
          Various federal, state and international labor laws govern our relationship with employees and affect operating costs. These laws include minimum wage requirements, overtime, unemployment tax rates, workers’ compensation rates paid, leaves of absence, mandated health and other benefits, and citizenship

14


Table of Contents

requirements. Significant additional government-imposed increases or new requirements in these areas could materially affect our business, financial condition, operating results or cash flow.
          In the event our employee-related costs rise significantly, we may have to curtail the number of our employees or shut down certain manufacturing facilities. Any such actions would be not only costly but could also materially adversely affect our business.
We depend on the services of key executives, the loss of whom could materially harm our business.
          Our senior executives are important to our success because they are instrumental in setting our strategic direction, operating our business, maintaining and expanding relationships with distributors, identifying, recruiting and training key personnel, identifying expansion opportunities and arranging necessary financing. Losing the services of any of these individuals could adversely affect our business until a suitable replacement could be found. We believe that our senior executives could not easily be replaced with executives of equal experience and capabilities. Although we have entered into employment agreements with certain of our key domestic executives, we cannot prevent our key executives from terminating their employment with us. We do not maintain key person life insurance policies on any of our executives.
If we lose certain of our key sales, marketing or engineering personnel, our business may be adversely affected.
          Our success depends on our ability to recruit, retain and motivate highly skilled sales, marketing and engineering personnel. Competition for these persons in our industry is intense and we may not be able to successfully recruit, train or retain qualified personnel. If we fail to retain and recruit the necessary personnel, our business and our ability to obtain new customers, develop new products and provide acceptable levels of customer service could suffer. If certain of these key personnel were to terminate their employment with us, we may experience difficulty replacing them, and our business could be harmed.
We are subject to environmental laws that could impose significant costs on us and the failure to comply with such laws could subject us to sanctions and material fines and expenses.
          We are subject to a variety of federal, state, local, foreign and provincial environmental laws and regulations, including those governing the discharge of pollutants into the air or water, the management and disposal of hazardous substances and wastes and the responsibility to investigate and cleanup contaminated sites that are or were owned, leased, operated or used by us or our predecessors. Some of these laws and regulations require us to obtain permits, which contain terms and conditions that impose limitations on our ability to emit and discharge hazardous materials into the environment and periodically may be subject to modification, renewal and revocation by issuing authorities. Fines and penalties may be imposed for non-compliance with applicable environmental laws and regulations and the failure to have or to comply with the terms and conditions of required permits. From time to time our operations may not be in full compliance with the terms and conditions of our permits. We periodically review our procedures and policies for compliance with environmental laws and requirements. We believe that our operations generally are in material compliance with applicable environmental laws, requirements and permits and that any lapses in compliance would not be expected to result in us incurring material liability or cost to achieve compliance. Historically, the costs of achieving and maintaining compliance with environmental laws, and requirements and permits have not been material; however, the operation of manufacturing plants entails risks in these areas, and a failure by us to comply with applicable environmental laws, regulations, or permits could result in civil or criminal fines, penalties, enforcement actions, third party claims for property damage and personal injury, requirements to clean up property or to pay for the costs of cleanup, or regulatory or judicial orders enjoining or curtailing operations or requiring corrective measures, including the installation of pollution control equipment or remedial actions. Moreover, if applicable environmental laws and regulations, or the interpretation or enforcement thereof, become more stringent in the future, we could incur capital or operating costs beyond those currently anticipated.

Table of Contents

          Certain environmental laws in the United States, such as the federal Superfund law and similar state laws, impose liability for the cost of investigation or remediation of contaminated sites upon the current or, in some cases, the former site owners or operators and upon parties who arranged for the disposal of wastes or transported or sent those wastes to an off-site facility for treatment or disposal, regardless of when the release of hazardous substances occurred or the lawfulness of the activities giving rise to the release. Such liability can be imposed without regard to fault and, under certain circumstances, can be joint and several, resulting in one party being held responsible for the entire obligation. As a practical matter, however, the costs of investigation and remediation generally are allocated among the viable responsible parties on some form of equitable basis. Liability also may include damages to natural resources. We are not listed as a potentially responsible party in connection with any sites we currently or formerly owned or operated or any off-site waste disposal facility. There is contamination at some of our current facilities, primarily related to historical operations at those sites, for which we could be liable under these environmental laws. The potential for contamination exists due to historic activities at our other current or former sites. We currently are not undertaking any remediation or investigations and our costs or liability in connection with potential contamination conditions at our facilities cannot be predicted at this time because the potential existence of contamination has not been investigated or not enough is known about the environmental conditions or likely remedial requirements. Currently, other parties with contractual liability are addressing or have plans or obligations to address those contamination conditions that may pose a material risk to human health, safety or the environment. In addition, while we attempt to evaluate the risk of liability at the time we acquire them, there may be environmental conditions currently unknown to us relating to our prior, existing or future sites or operations or those of predecessor companies whose liabilities we may have assumed or acquired which could have a material adverse effect on our business.
          We are being indemnified, or expect to be indemnified by third parties subject to certain caps or limitations on the indemnification, for certain environmental costs and liabilities. Accordingly, based on the indemnification and the experience with similar sites of the environmental consultants who we have hired, we do not expect such costs and liabilities to have a material adverse effect on our business, operations or earnings. We cannot assure you, however, that these third parties will in fact satisfy their indemnification obligations. If these third parties become unable to, or otherwise do not, comply with their respective indemnity obligations, or if certain contamination or other liability for which we are obligated is not subject to these indemnities, we could become subject to significant liabilities.
We face additional costs associated with our post-retirement and post-employment obligations to employees which could have an adverse effect on our financial condition.
          As part of the PTH Acquisition, we agreed to assume pension plan liabilities for active U.S. employees under the Retirement Plan for Power Transmission Employees of Colfax, the Ameridrives International Pension Fund for Hourly Employees Represented by United Steelworkers of America, Local 3199-10, and the Colfax PT Pension Plan, collectively referred to as the Prior Plans. We have established a defined benefit plan, or New Plan, mirroring the benefits provided under the Prior Plans. The New Plan accepted a spinoff of assets and liabilities from the Prior Plans, in accordance with Section 414(l) of the Internal Revenue Code, or the Code, with such assets and liabilities relating to active U.S. employees as of the closing of the PTH Acquisition. Given the funded status of the Prior Plans and the asset allocation requirements of Code Section 414(l), liabilities under the New Plan greatly exceed the assets that were transferred from the Prior Plans. The accumulated benefit obligation (not including accumulated benefit obligations of non-U.S.  pension plans in the amount of $2.9 million) was approximately $24.8 million as of December 31, 2005 while the fair value of plan assets was approximately $5.8 million as of December 31, 2005. As the New Plan has a considerable funding deficit, the cash funding requirements are expected to be substantial over the next several years, and could have a material adverse effect on our financial condition. As of September 29, 2006, funding requirements were estimated to be $0.6 million during the remainder of 2006, $3.6 million in 2007, $2.5 million in 2008 and $1.9 million annually thereafter until 2011. These amounts are based on actuarial assumptions and actual amounts could be materially different.

          Additionally, as part of the PTH Acquisition, we agreed to assume all pension plan liabilities related to non-U.S.  employees. The accumulated benefit obligations of non-U.S.  pension plans were approximately $2.9 million as of December 31, 2005. There are no assets associated with these plans.
          Finally, as part of the PTH Acquisition, we also agreed to assume all post-employment and post-retirement welfare benefit obligations with respect to active U.S. employees. The benefit obligation for post-retirement benefits, which are not funded, was approximately $8.3 million as of September 29, 2006.
          For a description of the post-retirement and post-employment costs, see Note 9 to the audited financial statements included elsewhere in this prospectus.
Our future success depends on our ability to integrate acquired companies and manage our growth effectively.
          Our growth through acquisitions has placed, and will continue to place, significant demands on our management, operational and financial resources. Realization of the benefits of acquisitions often requires integration of some or all of the acquired companies’ sales and marketing, distribution, manufacturing, engineering, finance and administrative organizations. Integration of companies demands substantial attention from senior management and the management of the acquired companies. In addition, we will continue to pursue new acquisitions, some of which could be material to our business if completed. We may not be able to integrate successfully our recent acquisitions or any future acquisitions, operate these acquired companies profitably, or realize the potential benefits from these acquisitions.
We may not be able to protect our intellectual property rights, brands or technology effectively, which could allow competitors to duplicate or replicate our technology and could adversely affect our ability to compete.
          We rely on a combination of patent, trademark, copyright and trade secret laws in the United States and other jurisdictions, as well as on license, non-disclosure, employee and consultant assignment and other agreements and domain names registrations in order to protect our proprietary technology and rights. Applications for protection of our intellectual property rights may not be allowed, and the rights, if granted, may not be maintained. In addition, third parties may infringe or challenge our intellectual property rights. In some cases, we rely on unpatented proprietary technology. It is possible that others will independently develop the same or similar technology or otherwise obtain access to our unpatented technology. In addition, in the ordinary course of our operations, we pursue potential claims from time to time relating to the protection of certain products and intellectual property rights, including with respect to some of our more profitable products. Such claims could be time consuming, expensive and divert resources. If we are unable to maintain the proprietary nature of our technologies or proprietary protection of our brands, our ability to market or be competitive with respect to some or all of our products may be affected, which could reduce our sales and profitability.
Goodwill comprises a significant portion of our total assets, and if we determine that goodwill has become impaired in the future, net income in such years may be materially and adversely affected.
          Goodwill represents the excess of cost over the fair market value of net assets acquired in business combinations. We review goodwill and other intangibles annually for impairment and any excess in carrying value over the estimated fair value is charged to the results of operations. Reduction in net income resulting from the write down or impairment of goodwill would affect financial results and could have a material and adverse impact upon the market price of our common stock.
Unplanned repairs or equipment outages could interrupt production and reduce income or cash flow.
          Unplanned repairs or equipment outages, including those due to natural disasters, could result in the disruption of our manufacturing processes. Any interruption in our manufacturing processes would interrupt our production of products, reduce our income and cash flow and could result in a material adverse effect on our business and financial condition.

Table of Contents

Our operations are highly dependent on information technology infrastructure and failures could significantly affect our business.
          We depend heavily on our information technology, or IT, infrastructure in order to achieve our business objectives. If we experience a problem that impairs this infrastructure, such as a computer virus, a problem with the functioning of an important IT application, or an intentional disruption of our IT systems by a third party, the resulting disruptions could impede our ability to record or process orders, manufacture and ship in a timely manner, or otherwise carry on our business in the ordinary course. Any such events could cause us to lose customers or revenue and could require us to incur significant expense to eliminate these problems and address related security concerns.
Our leverage could adversely affect our financial health and make us vulnerable to adverse economic and industry conditions.
          We have incurred indebtedness that is substantial relative to our stockholders’ investment. As of September 29, 2006, we had approximately $234.2 million of indebtedness outstanding and $27.6 million available under lines of credit. Our indebtedness has important consequences; for example, it could:
  make it more challenging for us to obtain additional financing to fund our business strategy and acquisitions, debt service requirements, capital expenditures and working capital;
 
  increase our vulnerability to interest rate changes and general adverse economic and industry conditions;
 
  require us to dedicate a substantial portion of our cash flow from operations to service our indebtedness, thereby reducing the availability of our cash flow to finance acquisitions and to fund working capital, capital expenditures, research and development efforts and other general corporate activities;
 
  make it difficult for us to fulfill our obligations under our credit and other debt agreements;
 
  limit our flexibility in planning for, or reacting to, changes in our business and our markets; and
 
  place us at a competitive disadvantage relative to our competitors that have less debt.
          Substantially all of our assets have been pledged as collateral against any outstanding borrowings under the credit agreement governing our senior revolving credit facility, or the Credit Agreement. In addition, our senior revolving credit facility requires us to maintain specified financial ratios and satisfy certain financial condition tests, which may require that we take action to reduce our debt or to act in a manner contrary to our business objectives. If an event of default under our senior revolving credit facility occurs, then the lenders could declare all amounts outstanding under the senior revolving credit facility, together with accrued interest, to be immediately due and payable. In addition, our senior revolving credit facility and the indentures governing our 9% senior secured notes and our 11 1 / 4 % senior notes have cross-default provisions such that a default under any one would constitute an event of default in any of the others.
We are subject to tax laws and regulations in many jurisdictions and the inability to successfully defend claims from taxing authorities related to our current or acquired businesses could adversely affect our operating results and financial position.
          We conduct business in many countries, which requires us to interpret the income tax laws and rulings in each of those taxing jurisdictions. Due to the subjectivity of tax laws between those jurisdictions as well as the subjectivity of factual interpretations, our estimates of income tax liabilities may differ from actual payments or assessments. Claims from taxing authorities related to these differences could have an adverse impact on our operating results and financial position.

Genstar Capital Partners III, L.P. and Stargen III, L.P. (together, the Genstar Funds) control us and may have conflicts of interest with our other stockholders in the future.
          The Genstar Funds own 65.8% of our equity and are able to control our affairs. After this offering, the Genstar Funds will beneficially own 34.6% of our common stock, or 30.6% if the underwriters exercise their over-allotment option in full. After the offering, the Genstar Funds will have significant influence over the election and removal of our directors and our corporate and management policies, including potential mergers or acquisitions, payment of dividends, asset sales and other significant corporate transactions. This concentration of ownership may delay or deter possible changes in control of our company, which may reduce the market price of our common stock. We cannot assure you that the interests of the Genstar Funds will coincide with your interests.
Risks Related to this Offering
The market price of our common stock may be volatile, which could cause the value of your investment to decline.
          Securities markets worldwide experience significant price and volume fluctuations. This market volatility, as well as general economic, market or political conditions, war and incidents of terrorism and acts of God could reduce the market price of our common stock notwithstanding our operating performance. In addition, our operating results could be below the expectations of public market analysts and investors and, in response, the market price of our common stock could decrease significantly. You may be unable to resell your shares of our common stock at or above the initial public offering price.
          Furthermore, following periods of market volatility in the price of a company’s securities, security holders have sometimes instituted class action litigation. If the market value of our stock experiences adverse fluctuations and we become involved in this type of litigation, regardless of the outcome, we could incur substantial legal costs and our management’s attention could be diverted from the operation of our business, causing our business to suffer.
We cannot assure you that an active trading market will develop for our stock.
          There has never been a public market for our common stock. While we have filed an application for the listing of our common stock on The NASDAQ Global Market, an active public market for our common stock may not develop or be sustained after this offering. If a market does not develop or is not sustained, it may be difficult for you to sell your shares of common stock at a price that is attractive to you or at all. The initial public offering price of our common stock will be determined through negotiations between the underwriters, us and the selling stockholders and may not be indicative of the price that will prevail in the open market following this offering.
A substantial number of our shares of common stock may be sold in the public market by our principal stockholders, which could adversely affect the market price of our shares, which in turn could negatively impact your investment in us.
          Future sales of substantial amounts of our shares of common stock in the public market (or the perception that such sales may occur) could adversely affect market prices of our common stock prevailing from time to time and could impair our ability to raise capital through future sales of our equity or equity-related securities at a time and price that we deem appropriate. Such sales could create public perception of difficulties or problems with our business.
          Upon completion of this offering, we will have 23,087,591 shares of common stock issued and outstanding and no options to purchase shares of our common stock. All of the shares we and the selling stockholders are selling in this offering, plus any shares sold upon the exercise of the underwriters’ over-allotment option, will be freely tradeable without restriction under the Securities Act of 1933, as amended, or the Securities Act, unless purchased by our affiliates. Upon completion of this offering, 13,087,591 shares of our common stock will be restricted or controlled securities within the meaning of Rule 144

19


Table of Contents

under the Securities Act (11,587,591 shares of common stock if the underwriters’ over-allotment option is exercised in full). The rules affecting the sale of these securities are summarized under “Shares Eligible for Future Sale.” Following this offering, without giving effect to the over-allotment option, stockholders that collectively own 13,087,591 shares of our common stock will have registration rights with respect to their shares. See “Certain Relationships and Related Transactions — Registration Rights Agreement.”
          Subject to certain exceptions described under the caption “Underwriting,” we and all of our directors and executive officers and certain of our stockholders have agreed not to offer, sell or agree to sell, directly or indirectly, any shares of common stock without the permission of the underwriters for a period of 180 days from the date of this prospectus. The 180-day restricted period will be automatically extended if (1) during the last 17 days of the 180-day restricted period we issue an earning release or material news or a material event relating to our business occurs or (2) prior to the expiration of the 180-day restricted period, we announce that we will release earnings results or become aware that material news or a material event will occur during the 16-day period beginning on the last day of the 180-day restricted period, in which case the restrictions described above will continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event. When this period expires we and our locked-up stockholders will be able to sell our shares in the public market. Sales of a substantial number of such shares upon expiration, or early release, of the lock-up (or the perception that such sales may occur) could cause our share price to decline.
          Our principal stockholders hold (and following completion of this offering will continue to hold) shares of our common stock in which they have a very large unrealized gain, and these stockholders may wish, to the extent they may permissibly do so, to realize some or all of that gain relatively quickly by selling some or all of their shares, which could cause the market price of our common stock to decline.
          We also may issue our shares of common stock from time to time as consideration for future acquisitions and investments or for other reasons. If any such acquisition or investment is significant, the number of shares that we may issue may in turn be significant. We may also grant registration rights covering those shares in connection with any such acquisitions and investments.
You will experience immediate and substantial dilution.
          The initial public offering price of our common stock will be substantially higher than the net tangible book value per share of our outstanding common stock. Accordingly, if you purchase common stock in this offering, you will suffer immediate and substantial dilution of your investment. Based upon the issuance and sale of 3,333,334 shares of common stock by us at an assumed initial public offering price of $15.00 per share (the midpoint of the initial public offering price range indicated on the cover of this prospectus), you will incur immediate dilution of approximately $17.93 in the net tangible book value per share.
Because we have not paid dividends in the past and do not anticipate paying dividends on our common stock in the foreseeable future, you should not expect to receive dividends on shares of our common stock.
          We have no present plans to pay cash dividends to our stockholders and, for the foreseeable future, intend to retain all of our earnings for use in our business. The decision whether to pay dividends will be made by our board of directors in light of conditions then existing, including factors such as our results of operations, financial condition and capital requirements, and business conditions. In addition, the Credit Agreement governing the senior revolving credit facility and the indentures governing the 9% senior secured notes and the 11 1 / 4 % senior notes contain covenants limiting the payment of cash dividends. Consequently, you should not rely on dividends in order to receive a return on your investment.

These estimates have been derived from our management’s knowledge and experience in the markets in which we operate, as well as information obtained from surveys, reports by market research firms, our customers, distributors, suppliers, trade and business organizations and other contacts in the markets in which we operate. References herein to our being a leader in a market or product category refers to our belief that we have a leading market share position in each specified market, unless the context otherwise requires, and do not take into account competitive products outside our industry. Statements in this prospectus relating to our market share do not include data for products that are produced internally by other vertically integrated manufacturers.
CAUTIONARY NOTICE REGARDING FORWARD-LOOKING STATEMENTS
          This prospectus, including information generally located under the headings “Summary,” “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Business,” contains forward-looking statements. These forward-looking statements generally relate to our strategies, plans and objectives for, and potential results of, future operations and are based upon management’s current plans and beliefs or current estimates of future results or trends. Whenever you read a statement that is not solely a statement of historical fact, such as when we state that we “believe,” “expect,” “anticipate” or “plan” that an event will occur and other similar statements, you should understand that our expectations may not be correct, although we believe they are reasonable, and that our plans may change. We do not guarantee that the transactions and events described in this prospectus will happen as described or that any positive trends noted in this prospectus will continue.
          Forward-looking statements regarding management’s present plans or expectations for new product offerings, capital expenditures, increasing sales, cost-saving strategies and growth involve risks and uncertainties relative to return expectations, allocation of resources and changing economic or competitive conditions, which could cause actual results to differ from present plans or expectations and such differences could be material. Similarly, forward-looking statements regarding management’s present expectations for operating results and cash flow involve risks and uncertainties relative to these and other factors including:
  competitive factors in the industry in which we operate;
 
  changes in general economic conditions and the cyclical nature of the markets in which we operate;
 
  our dependence on our distribution network;
 
  our ability to invest in, develop or adapt to changing technologies and manufacturing techniques;
 
  international risks on our operations;

  our substantial indebtedness; and
 
  other factors that are described under “Risk Factors.”
          We caution you that the foregoing list of important factors is not exclusive. In addition, in light of these risks and uncertainties, the matters referred to in the forward-looking statements contained in this prospectus may not in fact occur. The forward-looking statements contained in this prospectus are current as of the date of the prospectus.

USE OF PROCEEDS
          We estimate that we will receive net proceeds from this offering of approximately $41.5 million, after deducting underwriting discounts and commissions and other estimated expenses of $8.5 million payable by us. This estimate assumes an initial public offering price of $15.00 per share, the midpoint of the range set forth on the cover page of this prospectus. A $1.00 increase (decrease) in the assumed initial public offering price of $15.00 per share would increase (decrease) the net proceeds to us from this offering by $3.1 million, assuming the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting the estimated underwriting discounts and commissions and estimated expenses payable by us. We will not receive any of the proceeds from the sale of shares by the selling stockholders. We intend to use the net proceeds from this offering as follows:
  •  to redeem on a pro rata basis, pursuant to the terms of the indenture governing the 11 1 / 4 % senior notes due 2013, 35 percent of our 11 1 / 4 % senior notes for $24.4 million, which amount includes $2.4 million of applicable premium and $0.3 million of accrued interest; and
 
  for general corporate purposes.
          Based on its holdings of the 11 1 / 4 % senior notes as of November 25, 2006, MLEMEA could receive total proceeds of $13.8 million from the redemption of the 11 1 / 4 % senior notes. See “Underwriting — Other Relationships.”
          We incurred indebtedness under the 11 1 / 4 % senior notes due 2013 to complete the Hay Hall Acquisition.
DIVIDEND POLICY
          We intend to retain all future earnings, if any, for use in the operation of our business and to fund future growth. We do not anticipate paying any dividends for the foreseeable future, and the Credit Agreement governing the senior revolving credit facility and the indentures governing the 9% senior secured notes and 11 1 / 4 % senior notes limit our ability to pay dividends or other distributions on our common stock. See “Description of Indebtedness.” We may incur other obligations in the future that will further limit our ability to pay dividends. The decision whether to pay dividends will be made by our board of directors in light of conditions then existing, including factors such as our results of operations, financial condition and requirements, business conditions and covenants under any applicable contractual arrangements.

  on an actual basis; and
 
  •  on an as adjusted basis to give effect to the conversion of all shares of our preferred stock into 17,750,000 shares of common stock, which will occur automatically upon the closing of this offering, and the sale by us of 3,333,334 shares of common stock at the assumed initial public offering price of $15.00 per share, the midpoint of the range set forth on the cover page of this prospectus, in this offering and our receipt of the net offering proceeds therefrom, after deducting estimated underwriting discounts and commissions and offering expenses. In addition, the table reflects the redemption of $21.7 million of our 11 1 / 4 % senior notes and the estimated 11 1 / 4 % prepayment premium, which amounted to approximately $2.4 million, and payment of accrued interest of approximately $0.3 million.

DILUTION
          Dilution is the amount by which the offering price paid by the purchasers of the common stock to be sold in this offering exceeds the net tangible book value per share of common stock after this offering. Net tangible book value per share is determined at any date by subtracting our total liabilities from the total book value of our tangible assets and dividing the difference by the number of shares of common stock deemed to be outstanding at that date. Shares of common stock deemed to be outstanding excludes restricted shares of common stock for which the restrictions have not lapsed based on employee service.
          Our net tangible book value as of September 29, 2006 was $(101.9) million, or $(153.70) per share of common stock. After giving effect to the two-for-one reverse split of our common shares and conversion of our preferred stock into shares of common stock at a ratio of 2:1, our net tangible book value per share would be $(307.40) and $(5.64), respectively. After giving effect to the reverse stock split, conversion of the preferred stock and the receipt and our intended use of approximately $41.5 million of estimated net proceeds from our sale of 3,333,334 shares of common stock in the offering at an assumed offering price of $15.00 per share, the midpoint of the range set forth on the cover page of this prospectus, our pro forma net tangible book value as of September 29, 2006 would have been approximately $(62.8) million, or $(2.93) per share of common stock, which amount includes costs and expenses related to the redemption of a portion of the 11 1 / 4 % senior notes. This represents an immediate increase in pro forma net tangible book value of $2.71 per share to existing stockholders and an immediate dilution of $17.93 per share to new investors purchasing shares of common stock in the offering. The following table illustrates this substantial and immediate per share dilution to new investors:

          A $1.00 increase (decrease) in the assumed initial public offering price of $15.00 per share would decrease (increase) our pro forma net tangible book deficit by $3.1 million and the pro forma net tangible book deficit per share after this offering by $0.14 per share and would increase (decrease) the dilution per share to new investors in this offering by $0.86, assuming the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting the estimated underwriting discounts and commissions and estimated expenses payable by us.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS
          The following unaudited pro forma condensed combined financial statements are presented to illustrate the estimated effects of the Hay Hall Acquisition in February 2006 and related transactions on our financial condition and results of operations. We have derived our historical consolidated financial data for the year ended December 31, 2005 from the audited consolidated financial statements and related notes included elsewhere in this prospectus. We have derived the historical consolidated financial data of our company for the nine months ended September 29, 2006 from the unaudited consolidated interim financial statements and related notes included elsewhere in this prospectus. We have derived the historical consolidated financial data of Hay Hall for the year ended December 31, 2005 from the audited consolidated financial statements of Hay Hall included elsewhere in this prospectus. We have not included an unaudited pro forma balance sheet since the balance sheet at September 29, 2006 included in this prospectus gives effect to the Hay Hall acquisition. Hay Hall historical financial information has been reconciled from U.K. GAAP to U.S. GAAP in all periods presented and all amounts have been converted from U.K. pounds sterling to U.S. dollars for the purpose of these pro forma financial statements.
          The unaudited pro forma condensed combined statements of operations for the year ended December 31, 2005 and the nine months ended September 29, 2006 assume that the Hay Hall Acquisition and related transactions, as applicable, took place on January 1, 2005, the beginning of our 2005 fiscal year. The information presented in the unaudited pro forma condensed combined financial statements is not necessarily indicative of our financial position or results of operations that would have occurred if the Hay Hall Acquisition and related transactions had been completed as of the dates indicated, nor should it be construed as being a representation of our future financial position or results of operations.
          The unaudited pro forma condensed combined financial statements are presented for illustrative purposes only and do not purport to be indicative of the operating results that might have been achieved had the transactions occurred as of an earlier date, and do not purport to be indicative of future operating results.
          The pro forma adjustments are based upon available information and certain assumptions that we believe are reasonable under the circumstances. These adjustments are more fully described in the notes to the unaudited pro forma condensed combined financial statements below.
          The unaudited pro forma condensed combined financial statements should be read in conjunction with the accompanying notes and assumptions, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” the consolidated financial statements of Altra and related notes, the consolidated financial statements of Hay Hall and the related notes and the other financial information included elsewhere in this prospectus.

(1)  Weighted average shares of common stock outstanding and net income per share are based on historical information and do not take into effect the conversion of preferred stock to common stock or the two for one reverse split of common stock.
 
(2)  EBITDA is defined as earnings before interest, income taxes, depreciation and amortization. EBITDA is used by us as a performance measure. Management believes that EBITDA provides relevant information for our investors because it is useful for trending, analyzing and benchmarking the performance and value of our business. Management also believes that EBITDA is useful in assessing current performance compared with the historical performance of our Predecessor because significant line items within our income statements such as depreciation, amortization and interest expense were significantly impacted by the PTH Acquisition. Internally, EBITDA is used as a financial measure to assess the operating performance and is an important measure in our incentive compensation plans. EBITDA has important limitations, and should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP. For example, EBITDA does not reflect:
  cash expenditures, or future requirements, for capital expenditures or contractual commitments;
 
  changes in, or cash requirements for, working capital needs;
 
  the significant interest expense, or the cash requirements necessary to service interest or principal payments, on debts;
 
  tax distributions that would represent a reduction in cash available to us; and
 
  any cash requirements for assets being depreciated and amortized that may have to be replaced in the future.

  EBITDA is not a recognized measurement under GAAP, and when analyzing our operating performance, you should use EBITDA in addition to, and not as an alternative for, income (loss) from operations and net income (loss) (as determined in accordance with GAAP). Because not all companies use identical calculations, our presentation of EBITDA and may not be comparable to similarly titled measures of other companies. The amounts shown for EBITDA also differ from the amounts calculated under similarly titled definitions in our debt instruments, which are further

  adjusted to reflect certain other cash and non-cash charges and are used to determine compliance with financial covenants and our ability to engage in certain activities, such as incurring additional debt and making certain restricted payments.
 
  To compensate for the limitations of EBITDA, we utilize several GAAP measures to review our performance. These GAAP measures include, but are not limited to, net income (loss), income (loss) from operations, cash provided by (used in) operations, cash provided by (used in) investing activities and cash provided by (used in) financing activities. These important GAAP measures allow management to, among other things, review and understand our use of cash from period to period, compare our operations with competitors on a consistent basis and understand the revenues and expenses matched to each other for the applicable reporting period. We believe that the use of these GAAP measures, supplemented by the use of EBITDA, allows us to have a greater understanding of our performance and allows us to adapt to changing trends and business opportunities.

(3)  These amounts include expenses relating to non-cash inventory step-up costs, management fees and transaction expenses associated with acquisitions which, if subtracted out, would result in a higher EBITDA. Inventory step-up costs accounted for $2.3 million, $1.7 million, $1.7 million and $1.7 million, respectively, for the nine months ended September 29, 2006, for the nine months ended September 30, 2005, the twelve months ended December 31, 2005 and the Period from December 1, 2004 through December 31, 2004. Management fees consisted of $0.8 million, $0.8 million, $1.0 million and $0.1 million, respectively, for the nine months ended September 29, 2006, for the nine months ended September 30, 2005, the twelve months ended December 31, 2005 and the Period from December 1, 2004 through December 31, 2004. Transaction fees and expenses associated with acquisitions accounted for $1.0 million and $4.4 million, respectively, for the nine months ended September 29, 2006 and the period from December 1, 2004 through December 31, 2004.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS
          The following discussion of our financial condition and results of operations should be read together with “Selected Historical Financial And Other Data,” “Unaudited Pro Forma Condensed Combined Financial Statements” and the financial statements and related notes included elsewhere in this prospectus. The following discussion includes forward-looking statements. For a discussion of important factors that could cause actual results to differ materially from the results referred to in the forward-looking statements, see “Cautionary Notice Regarding Forward-Looking Statements.”
Overview
          We are a leading global designer, producer and marketer of a wide range of MPT and motion control products with a presence in over 70 countries. Our global sales and marketing network includes over 700 direct OEM customers and over 3,000 distributor outlets. Our product portfolio includes industrial clutches and brakes, enclosed gear drives, open gearing, couplings, engineered bearing assemblies, linear components and other related products. Our products serve a wide variety of end markets including energy, general industrial, material handling, mining, transportation and turf and garden. We primarily sell our products to a wide range of OEMs and through long-standing relationships with industrial distributors such as Motion Industries, Applied Industrial Technologies, Kaman Industrial Technologies and W.W. Grainger.
          Our net sales have grown at a compound annual growth rate of approximately 13% over the last three fiscal years. We believe this growth has been a result of recent acquisitions, greater overall global demand for our products due to a strengthening economy, increased consumption in certain geographic markets such as China, expansion of our relationships with our customers and distributors and implementation of improved sales and marketing initiatives.
          We improved our gross profit margin and operating profit margin every year from fiscal year 2002 through fiscal year 2005 by implementing strategic price increases, utilizing low-cost country sourcing of components, increasing our productivity and employing a more efficient sales and marketing strategy.
          While the power transmission industry has undergone some consolidation, we estimate that in 2005 the top eight broad-based MPT companies represented approximately 21% of the U.S. power transmission market. The remainder of the power transmission industry remains fragmented with many small and family-owned companies that cater to a specific market niche often due to their narrow product offerings. We believe that consolidation in our industry will continue because of the increasing demand for global distribution channels, broader product mixes and better brand recognition to compete in this industry.
Key Components of Results of Operations
          Net sales. We derive revenues primarily from selling products that are either incorporated into products sold by OEMs to end users directly or sold through industrial distributors. Although we have exclusive arrangements with less than 5% of our distributors, we believe our long history of serving the replacement part market will continue to yield recurring purchases from our customers resulting in consistent revenues. Our net sales are derived by eliminating allowances for sales returns, cash discount and other deductions from revenues.
          Cost of sales. Cost of sales includes direct expenses we incur in producing our products. This includes the amounts we pay for our raw materials, energy costs and labor expenses. Our cost of sales has increased due to increasing prices in our raw materials, energy increases and minimum wage increases. We have offset certain cost increases by passing through these costs to our customers by way of product price increases or surcharges, as well as by focusing on operating efficiencies and cost savings programs.

          Selling, general and administrative expense. Selling, general and administrative expense includes departmental costs for executive, legal and administrative services, finance, telecommunications, facilities and information technology.
          Research and development expense. Research and development expense primarily consists of personnel expenses and contract services associated with the development of our products.
History and Recent Acquisitions
          Our current business began with the acquisition by Colfax of the MPT group of Zurn Technologies, Inc. in December 1996. Colfax subsequently acquired Industrial Clutch Corp. in May 1997, Nuttall Gear Corp. in July 1997 and the Boston Gear and Delroyd Worm Gear brands in August 1997 as part of Colfax’s acquisition of Imo Industries, Inc. In February 2000, Colfax acquired Warner Electric, Inc., which sold products under the Warner Electric, Formsprag Clutch, Stieber and Wichita Clutch brands. Colfax formed PTH in June 2004 to serve as a holding company for all of these power transmission businesses.
          On November 30, 2004, we acquired our original core business through the acquisition of PTH from Colfax for $180.0 million in cash.
          On October 22, 2004, The Kilian Company, or Kilian, a company formed at the direction of Genstar Capital, our principal equity sponsor, acquired Kilian Manufacturing Corporation from Timken U.S. Corporation for $8.8 million in cash and the assumption of $12.2 million of debt. At the completion of the PTH Acquisition, (i) all of the outstanding shares of Kilian capital stock were exchanged for approximately $8.8 million of shares of our capital stock and Kilian and its subsidiaries were transferred to our wholly owned subsidiary, Altra Industrial and (ii) all outstanding debt of Kilian was retired with a portion of the proceeds of the sale of Altra Industrial’s 9.0% senior secured notes due 2011, or the 9% senior secured notes.
          On November 7, 2005, we entered into a purchase agreement with the shareholders of Hay Hall pursuant to which we agreed to acquire all of the outstanding share capital of Hay Hall for $50.3 million. The acquisition closed on February 10, 2006 and Hay Hall and its subsidiaries became our indirect wholly owned subsidiaries. We paid $6.0 million of the total purchase price in the form of deferred consideration. At the closing of the Hay Hall Acquisition, we deposited such deferred consideration into an escrow account for the benefit of the current Hay Hall shareholders, which is represented by a loan note. While the current Hay Hall shareholders hold the note, their rights are limited to receiving the amount of the deferred consideration placed in the escrow account. They have no recourse against us unless we take action to prevent or interfere in the release of such funds from the escrow account.
          Hay Hall is a U.K.-based holding company that is focused primarily on the manufacture of flexible couplings and clutch brakes. Through Hay Hall, we acquired 15 strong brands in complementary product lines, improved customer leverage and expanded geographic presence in over 11 countries. Hay Hall’s product offerings diversified our revenue base and strengthened our key product areas, such as electric clutches, brakes and couplings. Matrix International, Inertia Dynamics and Twiflex, three Hay Hall businesses, combined with Warner Electric, Wichita Clutch, Formsprag Clutch and Stieber, make the consolidated company one of the largest individual manufacturer of industrial clutches and brakes in the world.
          The Hay Hall Acquisition did not create a new reportable segment.
          On May 18, 2006, Altra Industrial acquired substantially all of the assets of Bear Linear for $5.0 million. Approximately $3.5 million was paid at closing and the remaining $1.5 million is payable over the next two and a half years. Bear Linear manufactures high value-added linear actuators which are electromechanical power transmission devices designed to move and position loads linearly for mobile off-highway and industrial applications. Bear Linear’s product design and engineering expertise, coupled with the Company’s sourcing alliance with a low cost country manufacturer, were critical components in Altra’s strategic expansion into the motion control market.

Cost Savings and Productivity Enhancement Initiatives
          Our Predecessor enacted significant cost savings programs prior to our acquisition of PTH and we subsequently enacted other cost savings programs to reduce overall cost structure and improve cash flows. Cost reduction programs included the consolidation of facilities, headcount reductions and reduction in overhead costs, which resulted in restructuring charges, asset impairment and transition expenses of $11.1 million in the year ended December 31, 2003. Cash outflows related to the restructuring programs were $2.2 million in 2004 and $13.9 million in 2003. The financial effects of some of the specific cost reduction programs are listed below:
  In 2003, our Predecessor incurred transition expenses, including relocation, training, recruiting and moving costs, directly related to implementing its restructuring activities amounting to $9.1 million.
 
  In 2003, our Predecessor recorded a $2.0 million loss from the sale of certain real estate associated with facilities closed as a part of its restructuring activities.
 
  In 2005, we re-negotiated two of our U.S. collective bargaining agreements which we estimate provide for savings of $0.8 million annually.
 
  In 2006, we re-negotiated one of our U.S. collective bargaining agreements which we estimate provides for savings of $2.2 million annually.
Non-GAAP Financial Measures
          The discussion of Results of Operations below includes certain references to financial results on a “combined basis.” The combined results were prepared by adding the results of Altra Holdings, Inc. from inception on December 1, 2004 to December 31, 2004 to those from our Predecessor for the 11 month period ending November 30, 2004. This presentation is not in accordance with GAAP. The primary differences between the predecessor entity and the successor entity are the inclusion of Kilian in the successor and the successor’s book basis has been stepped up to fair value, such that the successor has additional depreciation, amortization and financing costs. The results of Kilian are included in Altra Holdings, Inc. for the period from December 1, 2004 through December 31, 2004. Management believes that this combined basis presentation provides useful information for our investors in the comparison to Predecessor trends and operating results. The combined results are not necessarily indicative of what our results of operations may have been if the PTH Acquisition and Kilian Transactions had been consummated earlier, nor should they be construed as being a representation of our future results of operations.

Results of Operations
Nine Months Ended September 29, 2006 Compared with Nine Months Ended September 30, 2005
Net sales
          Net sales increased $74.0 million, or 27.1%, from $273.5 million, for the nine months ended September 30, 2005 to $347.5 million for the nine months ended September 29, 2006. Net sales increased primarily due to the inclusion of Hay Hall in the results of the nine months ended September 29, 2006. Hay Hall’s net sales for the 33 week period from February 10, 2006 (the date of acquisition) through September 29, 2006 were $46.6 million. The majority of the remaining net increase was due to price increases which accounted for approximately $8.4 million, strong economic conditions at our customers in the steel, energy and mining industries which accounted for $11.4 million and increased sales to turf and garden OEM customers which accounted for $3.0 million.
Gross profit
          Gross profit increased $28.0 million, or 42.0%, from $66.6 million (24.4% of net sales), in the nine months ended September 30, 2005 to $94.6 million (27.2% of net sales) in the same period of 2006. The increase includes $9.0 million from Hay Hall for the nine months ended September 29, 2006. Excluding Hay Hall, gross profit increased approximately $19.0 million, or 28.5%, and gross profit as a percentage of sales increased to 28.4%. The remaining increase in gross profit is attributable to price increases during the first quarter of 2006, and an increase in material sourcing from lower cost geographies and manufacturing efficiencies implemented by the new management team in the second half of 2005. We were able to offset the impact of higher energy and raw materials costs by passing many of these costs on to our customers.
Selling, general and administrative expenses
          Selling, general and administrative expenses increased $11.4 million, or 24.7%, from $46.0 million in the nine months ended September 30, 2005 to $57.4 million in the nine months ended September 29, 2006. The increase in selling, general and administrative expenses is due to the inclusion of Hay Hall in 2006, which contributed $7.4 million to the increase, a $1.0 million transaction fee paid to Genstar

Capital, L.P., pursuant to our advisory services agreement, for advisory services provided in connection with the Hay Hall Acquisition calculated as 2% of the aggregate purchase price and increased salaries and professional fees. Excluding Hay Hall and the related transaction fee paid to Genstar Capital, L.P., selling, general and administrative expenses, as a percentage of net sales, decreased from 16.8% in the nine months ended September 30, 2005 to 16.3% in the nine months ended September 29, 2006, primarily due to operating efficiencies and cost savings measures that were put into place during the second half of 2005.
Research and development expenses
          Research and development expenses increased $0.3 million, or 8.9%, from $3.5 million in the nine months ended September 30, 2005 to $3.8 million in the nine months ended September 29, 2006. The increase in research and development expenses is due to higher average compensation rates and the timing of project expenses.
          Gain on curtailment of post-retirement benefit plan. In May, 2006 the Company renegotiated its contract with the labor union at its South Beloit, IL manufacturing facility. As a result of the renegotiation, participants in the Company’s pension plan ceased to accrue additional benefits starting July 3, 2006. Additionally, the other post retirement benefit plan has been terminated for all eligible participants who have not retired, or given notice to retire in 2006, by August 1, 2006. The Company recognized a non-cash gain associated with the curtailment of this plan in the third quarter of 2006 of $3.8 million.
Interest expense, net
          We recorded interest expense of $19.4 million during the nine months ended September 29, 2006, which was an increase of $4.7 million, or 32.3%, from the nine months ended September 30, 2005. The increase was due to the interest associated with the 11 1 / 4 % senior notes issued in connection with the Hay Hall Acquisition.
Provision for income taxes
          The provision for income taxes was $6.5 million, or 37.8% of income before taxes, for the nine months ended September 29, 2006, versus a provision of $1.2 million, or 50.7% of income before taxes, for the nine months ended September 30, 2005. The 2006 provision as a percent of income before taxes was lower than that of 2005 primarily due to the Hay Hall Acquisition and a greater proportion of taxable income in jurisdictions possessing lower statutory tax rates. For further discussion, refer to Note 10 to the unaudited condensed consolidated interim financial statements.

Year Ended December 31, 2005 Compared with Year Ended December 31, 2004
Net sales
          Net sales increased $59.8 million, or 19.7%, from $303.7 million on a combined basis, for the year ended December 31, 2004 to $363.5 million for the year ended December 31, 2005. Net sales increased primarily due to the inclusion of Kilian in the results of the year ended December 31, 2005. Kilian’s net sales for 2005 were $42.5 million. The remaining net increase was due to price increases, improving economic conditions at our customers in the steel, energy and petrochemical industries and increased sales of $4.7 million to certain transportation customers and $2.5 million in mining OEM customers, partially offset by a weakening at our turf and garden OEM customers. On a constant currency basis sales increased $58.7 million, or 19.3%, in 2005. Excluding Kilian, the constant currency increase in sales was $17.0 million, or 5.6%.
Gross profit
          Gross profit increased $21.0 million, or 29.7%, from $70.6 million (23.2% of net sales) on a combined basis, in 2004 to $91.5 million (25.2% of net sales) in 2005. The increase includes $9.1 million from Kilian for 2005. Excluding Kilian, gross profit increased approximately $11.9 million, or 16.8%, and gross profit as a percent of sales increased to 25.7%. The remaining increase in gross profit is attributable to price increases during the second half of 2005, an increase in low cost country material sourcing and manufacturing efficiencies implemented by the new management team. Savings from low cost country material sourcing and manufacturing efficiencies totaled $2.63 million.

Selling, general and administrative expenses
          Selling, general and administrative expenses increased $7.3 million, or 13.4%, from $54.3 million on a combined basis in 2004 to $61.6 million in 2005. The increase in selling, general and administrative expenses is due to the inclusion of Kilian in 2005, which contributed $3.4 million to the increase, $3.0 million of amortization of intangibles, and $1.0 million management fee paid to Genstar Capital, L.P., offset by cost savings initiatives of $1.0 million put in place during 2005. Excluding Kilian, selling, general and administrative expenses, as a percentage of net sales, increased from 17.9% in 2004 to 18.1% in 2005, primarily due to the amortization of intangibles and the management fee paid to Genstar Capital, L.P., offset by the cost savings initiatives. On a constant currency basis, selling, general and administrative expenses increased $6.4 million, or 11.8%, from $54.3 million, on a combined basis, in 2004. Excluding Kilian, selling, general and administrative expenses, on a constant currency basis, increased $3.0 million, or 5.6%, and was 17.9% of sales.
Research and development expenses
          Research and development expenses increased $0.4 million, or 8.3%, from $4.3 million on a combined basis in 2004 to $4.7 million in 2005. The increase was primarily due to development projects including the Foot/ Deck Mount Kopper Kool brake, a new clutch brake for the mining industry, spot brake technology, various elevator brakes and forklift brakes.
Gain on sale of assets
          Our Predecessor recorded a gain on sale of assets of $1.3 million during 2004 relating to the sale of surplus real estate. We recorded a gain of $0.1 million from the sale of surplus machinery during 2005.
Restructuring charge, asset impairment and transition expenses
          Restructuring charge, asset impairment and transition expenses decreased from $0.9 million on a combined basis in 2004 to zero in 2005 due to the ending of the program in 2004.
Interest expense, net
          We recorded interest expense of $19.5 million during 2005 primarily due to the 9% senior secured notes, the subordinated notes and the amortization of related deferred financing costs. On a combined basis, interest expense of $5.9 million was recorded during 2004.
Provision for income taxes
          The provision for income taxes was $3.3 million, or 57.2%, of income before taxes, for 2005, versus a combined provision of $5.2 million, or 83.9%, of income before taxes, for 2004. The 2004 provision as a percent of income before taxes was higher than that of 2005 primarily due to the impact of non-deductible transaction expenses incurred in connection with the PTH Acquisition in 2004. For further discussion, refer to Note 8 to the audited financial statements.
Year Ended December 31, 2004 Compared with Year Ended December 31, 2003
Net sales
          On a combined basis, net sales increased $36.8 million, or 13.8%, from $266.9 million in 2003 to $303.7 million in 2004. Net sales increased primarily due to continued strength in the turf and garden market, the general domestic industrial recovery and increased activity in the transportation and mining sectors which allowed us to increase sales prices and recover material surcharges of $1.4 million from customers. Combined net sales in 2004 also include $3.2 million of sales from Kilian which is included in the amounts presented since inception. On a constant currency basis, sales increased 11.6%.

Gross profit
          On a combined basis, gross profit increased $11.6 million, or 19.8%, from $58.9 million (22.1% of net sales) in 2003 to $70.6 million (23.2% of net sales) in 2004. The increase includes $0.9 million from Kilian since inception. Approximately two-thirds of the absolute increase in gross profit is due to increased net sales as discussed above. The remaining increase in gross profit and the improvement noted in the gross profit percentage is due to cost savings resulting from restructuring activities completed in prior years.
Selling, general and administrative expenses
          On a combined basis, selling, general and administrative expenses increased $4.8 million, or 9.7%, from $49.5 million in 2003 to $54.3 million in 2004. As a percentage of net sales, selling, general and administrative expenses decreased from 18.6% in 2003 to 17.9% in 2004. The change in selling, general and administrative expenses reflects the offsetting impact of increased sales commissions incurred from the increase in sales, incremental costs of approximately $1.0 million relating to corporate expenses not previously incurred by our Predecessor, a one-time $4.4 million transaction fee paid to Genstar Capital, L.P. and cost savings resulting from restructuring activities completed in prior years. On a constant currency basis, selling, general and administrative expenses increased by 7.1%, or $3.5 million, from $49.5 million in 2003 to $52.9 million in 2004.
Research and development expenses
          Research and development expenses increased $0.9 million, or 25.2%, from $3.5 million in 2003 to $4.3 million in 2004, on a combined basis. The increase was due to the change in currency valuations as a result of a higher average rate for the Euro in 2004 and development projects for the turf and garden industry.
Restructuring charge, asset impairment and transition expenses
          Our Predecessor recorded a restructuring charge, asset impairment and transition expenses of $0.9 million in 2004 primarily as a result of relocation, training, recruiting and moving costs incurred to complete restructuring activities begun in 2002. These costs were significantly below the amounts recorded in prior years when the majority of the restructuring activities, as described under “— Cost Savings and Productivity Enhancement Initiatives,” were taking place.
Interest expense
          We recorded consolidated interest expense of $1.6 million during the period from inception on December 1, 2004 to December 31, 2004 primarily due to the 9% senior secured notes, the subordinated notes and the amortization of related deferred financing costs. Our Predecessor recorded interest expense of $4.3 million during the eleven months ended November 30, 2004. This amount was trending below the $5.4 million recognized in 2003 largely as a result of reductions in the amount of outstanding debt.
Other non-operating (income) expense
          Our Predecessor recorded a gain on sale of assets of $1.3 million during the 11 months ended November 30, 2004 relating to the sale of surplus real estate.
          Other non-operating expense was $0.1 million in 2004 compared to $0.5 million in 2003. The higher expense in 2003 is primarily due to the write-off of deferred loan costs of approximately $0.4 million associated with refinancing. There were no deferred loan costs written-off in 2004.

Provision for income taxes
          The provision for income taxes was $5.2 million on a combined basis in 2004, versus a benefit of $1.7 million for 2003. The increase in the provision for 2004 was primarily a result of the increase in our taxable income for the year. For further discussion, refer to Note 9 of the audited financial statements.

Seasonality
          We experience seasonality in our turf and garden business, which in recent years has represented approximately 10% of our net sales. As our large OEM customers prepare for the spring season, our shipments generally start increasing in December, peak in February and March, and begin to decline in April and May. This allows our customers to have inventory in place for the peak consumer purchasing periods for turf and garden products. Our low season is typically June through November and our customers in the turf and garden market. Seasonality for the turf and garden business is also affected by weather and the level of housing starts.

Inflation
          Inflation can affect the costs of goods and services we use. The majority of the countries that are of significance to us, from either a manufacturing or sales viewpoint, have in recent years enjoyed relatively low inflation. The competitive environment in which we operate inevitably creates pressure on us to provide our customers with cost-effective products and services.
Liquidity and Capital Resources
Overview
          Historically, our Predecessor financed capital and working capital requirements through a combination of cash flows from operating activities and borrowings from financial institutions and its former parent company, Colfax. We finance our capital and working capital requirements through a combination of cash flows from operating activities and borrowings under our senior revolving credit facility. We expect that our primary ongoing requirements for cash will be for working capital, debt service, capital expenditures and pension plan funding. If additional funds are needed for strategic acquisitions or other corporate purposes, we believe we could borrow additional funds or raise funds through the issuance of equity securities or asset sales.
Borrowings
          In connection with the PTH Acquisition, we incurred substantial indebtedness. To partially fund the PTH acquisition, our subsidiary, Altra Industrial, issued $165.0 million of 9% senior secured notes, we issued $14.0 million of subordinated notes to Caisse de dépôt et placement du Québec, or CDPQ, as a limited partner of Genstar Capital Partners III, L.P., and Altra Industrial entered into a $30.0 million senior revolving credit facility. In connection with our acquisition of Hay Hall in February 2006, Altra Industrial issued £33.0 million of 11 1 / 4 % senior notes. Based on an exchange rate of 1.7462 U.S. Dollars to U.K. pounds sterling (as of February 8, 2006), the proceeds from these notes were approximately $57.6 million. The notes are unsecured and are due in 2013. Interest on the 11 1 / 4 % senior notes is payable in U.K. pounds sterling semiannually in arrears on February 15 and August 15 of each year, commencing August 15, 2006.
          As of September 29, 2006, we had $1.5 million outstanding under the subordinated notes. As of September 29, 2006, Altra Industrial had outstanding $165.0 million of its 9% senior secured notes, $62.1 million of its 11 1 / 4 % senior notes and had no outstanding borrowings and $2.4 million of outstanding letters of credit under its senior revolving credit facility. As of September 29, 2006, we had approximately $234.2 million of total indebtedness outstanding (including capital leases) which on an annualized basis results in approximately $23.9 million of interest expense.
          Altra Industrial’s senior revolving credit facility provides for senior secured financing of up to $30.0 million, including $10.0 million available for letters of credit. The senior revolving credit facility requires Altra Industrial to comply with a minimum fixed charge coverage ratio of 1.10 for the four quarter period ended December 31, 2005 and 1.20 for all four quarter periods thereafter when availability falls below $12.5 million.
          Altra Industrial and all of its domestic subsidiaries are borrowers, or Borrowers, under the senior revolving credit facility. Certain of our existing and subsequently acquired or organized domestic subsidiaries which are not Borrowers do and will guarantee (on a senior secured basis) the senior revolving credit facility. Obligations of the other Borrowers under the senior revolving credit facility and the guarantees are secured by substantially all of the Borrowers’ assets and the assets of each of our existing and subsequently acquired or organized domestic subsidiaries that is a guarantor of our obligations under the senior revolving credit facility (with such subsidiaries being referred to as the “U.S. subsidiary guarantors”), including but not limited to: (a) a first-priority pledge of all the capital stock of subsidiaries held by the Borrowers or any U.S. subsidiary guarantor (which pledge, in the case of any foreign subsidiary, will be limited to 100% of any non-voting stock and 65% of the voting stock of such foreign

subsidiary) and (b) perfected first-priority security interests in and mortgages on substantially all tangible and intangible assets of each Borrower and U.S. subsidiary guarantor, including accounts receivable, inventory, equipment, general intangibles, investment property, intellectual property, real property (other than (i) leased real property and (ii) our existing and future real property located in the State of New York), cash and proceeds of the foregoing (in each case subject to materiality thresholds and other exceptions).
          We would suffer an event of default under the senior revolving credit facility for a change of control if: (i) after an initial public offering, a person or group, other than Genstar Capital and its affiliates, beneficially owns more than 35% of Altra Industrial’s stock and such amount is more than the amount of shares owned by Genstar Capital and its affiliates, (ii) Altra Industrial ceases to own or control 100% of each of its borrower subsidiaries, or (iii) a change of control occurs under the 9% senior secured notes; 11 1 / 4 % senior notes or any other subordinated indebtedness.
          We would cause an event of default under the senior revolving credit facility if an event of default occurs under the indenture or if there is a default under any other indebtedness any Borrower may have involving an aggregate amount of $3 million or more and such default: (i) occurs at final maturity of such debt, (ii) allows the lender thereunder to accelerate such debt or (iii) causes such debt to be required to be repaid prior to its stated maturity. An event of default would also occur under the senior revolving credit facility if any of the indebtedness under the senior revolving credit facility ceases to be senior in priority to any of our other contractually subordinated indebtedness, including the obligations under the 9% senior secured notes and the 11 1 / 4 % senior notes.
          Under the agreements governing Altra Industrial’s indebtedness, its subsidiaries are permitted to make dividend payments to Altra Industrial for use in its operations and to pay off its senior revolving credit facility and outstanding notes. Altra Industrial and its subsidiaries are restricted, however, from making dividend payments to Altra Holdings to pay off the CDPQ subordinated notes, subject to certain exceptions. As of September 29, 2006, Altra Industrial had prepaid approximately $12.5 million of the CDPQ subordinated notes on Altra Holdings’ behalf pursuant to these exceptions. In addition, the first priority liens against Altra Industrial, its subsidiaries and their assets created by Altra Industrial’s indebtedness limits its ability to sell or transfer such subsidiaries or assets.
          As of September 29, 2006, we were in compliance with all covenant requirements associated with all of our borrowings.
Capital Expenditures
          We made capital expenditures of approximately $6.1 million and $3.4 million in the nine months ended September 29, 2006 and September 30, 2005, respectively and $6.2 million for fiscal year 2005. These capital expenditures will support on-going business needs. We expect to spend approximately $10 million on capital expenditures in each of 2006 and 2007 .
          Our senior revolving credit facility imposes a maximum annual limit on our capital expenditures of $11.0 million for fiscal year 2006, $9.8 million for fiscal year 2007, $10.0 million for fiscal year 2008, and $10.3 million for fiscal year 2009 and each fiscal year thereafter, provided that unspent amounts from prior periods may be used in future fiscal years.
Pension Plans
          As of September 29, 2006, we had cash funding requirements associated with our pension plan which we estimated to be $0.6 million during the remainder of 2006, $3.6 million in 2007, $2.5 million in 2008 and $1.9 million annually thereafter until 2011. These amounts represent funding requirements for the previous pension benefits we provided our employees. In 2006, we eliminated pension benefits in one of our locations. These amounts are based on actuarial assumptions and actual amounts could be materially different. See Note 9 in the audited financial statements.

Comparative Cash Flows
          Cash and cash equivalents totaled $5.8 million at September 29, 2006 compared to $10.1 million at December 31, 2005. Net cash provided by operating activities for the nine months ended September 29, 2006 resulted mainly from cash provided by net income of $10.7 million and the add-back of non-cash depreciation, amortization and deferred financing costs of $12.0 million, loss on foreign currency of $0.5 million, stock based compensation expense of $0.4 million, deferred tax expense of $1.5 million, non-cash amortization of $2.3 million for inventory step-ups recorded as part of the Hay Hall Acquisition offset by a non-cash gain on the curtailment of a post-retirement benefit plan of $3.8 million, a net decrease in operating liabilities of $9.4 million, and by cash used from a net increase in operating assets of $3.2 million.
          Net cash used in investing activities of $60.4 million for the nine months ended September 29, 2006 resulted from $50.7 million used in the purchase of Hay Hall, $3.6 million used in the purchase of Bear Linear and $6.1 million used in the purchases of property, plant and equipment primarily for investment in manufacturing equipment.
          Net cash provided by financing activities of $45.0 million for the nine months ended September 29, 2006 consisted primarily of the proceeds of $57.6 million from the issuance of the 11 1 / 4 % senior notes in connection with the Hay Hall Acquisition and the $2.5 million in proceeds from a mortgage on our German manufacturing facility offset by principal debt payments of $12.5 million, payment of debt issuance costs of $2.5 million and approximately $0.1 million of capital lease payments.
          Net cash flow used in operating activities, in the year to date period ended September 30, 2005 resulted mainly from cash provided by net income of $1.2 million and the add-back of non-cash depreciation, amortization and deferred financing costs of $9.7 million, non-cash amortization of $1.7 million for inventory step-ups recorded as part of the PTH Acquisition and cash provided by a net decrease in operating assets of $1.5 million offset by a net decrease in operating liabilities of $2.1 million.
          Net cash used in investing activities of $4.0 million for the year to date period ended September 30, 2005 resulted from $3.4 million used in the purchases of property, plant and equipment primarily for investment in manufacturing equipment and for the consolidation of our IT infrastructure and from the $0.7 million final payment related to the acquisition of Kilian offset by $0.1 million in proceeds from the sale of certain fixed assets.
          Net cash used in financing activities of $0.6 million for the year to date period ended September 30, 2005 resulted from $0.7 million in payments under capital lease agreements and payment of $0.2 million of paid-in-kind interest, partially offset by $0.3 million in proceeds from the sale of convertible preferred stock.
          Cash and cash equivalents totaled $10.1 million at December 31, 2005 compared to $4.7 million at December 31, 2004. The primary source of funds for fiscal 2005 was cash provided by operating activities of $12.0 million. Net cash flow provided by operating activities resulted mainly from cash provided by net income of $2.5 million, and the add-back of non-cash depreciation, amortization and deferred financing costs of $13.1 million, deferred tax expense of $0.2 million, amortization of deferred compensation expense of $0.1 million, non-cash amortization of $1.7 million for inventory step-ups recorded as part of the PTH Acquisition which was offset by cash used by a net decrease in operating liabilities of $3.8 million and by cash used from a net increase in operating assets of $1.8 million.
          Net cash used in investing activities of $5.2 million for the fiscal year ended December 31, 2005 resulted from $6.2 million of purchases of property, plant and equipment primarily for investment in manufacturing equipment and for the consolidation of our IT infrastructure and from the $0.7 million final payment related to the acquisition of Kilian, partially offset by the sale of manufacturing equipment with proceeds of approximately $0.1 million and the return of approximately $1.6 million of the purchase price for PTH.

Table of Contents

          Net cash used by financing activities of $1.0 million for 2005 consisted primarily of payments of debt issuance expenses of $0.3 million, payment of $0.2 million of paid-in-kind interest and approximately $0.8 million of capital lease payments partially offset by proceeds of $0.4 million from the sale of preferred stock.
          Net cash flow provided by (used in) our Predecessor’s operating activities, in the 11 months ended November 30, 2004 and the year ended December 31, 2003 was $3.6 million and $(14.3) million, respectively. The increased cash flow provided by operating activities during 2004 was due primarily to increased sales and related operating results and a reduction in cash required to complete restructuring programs. The cash used in 2003 was primarily attributable to $13.9 million of cash required by the restructuring programs, an investment in inventories to support customer requirements during transition periods caused by restructuring programs and a reduction in accounts payable that had grown during 2002. See “Cost Savings and Productivity Enhancement Initiatives” for a description of the restructuring charges.
          Surplus property was sold which provided $4.4 million during the 11 months ended November 30, 2004 and $3.7 million in the year ended December 31, 2003.
          Our ability to make scheduled payments of principal and interest, to fund planned capital expenditures and to meet our pension plan funding obligations will depend on our ability to generate cash in the future. We believe that proceeds from this offering, cash flow from operations and available cash, together with available borrowings under our senior revolving credit facility will be adequate to meet our future liquidity requirements for the foreseeable future. However, our ability to generate cash is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control.
          We cannot assure you that our business will generate sufficient cash flow from operations, that any revenue growth or operating improvements will be realized or that future borrowings will be available under our senior revolving credit facility in amounts sufficient to enable us to service our indebtedness or to fund our other liquidity needs. Our ability to access capital in the long term will depend on the availability of capital markets and pricing on commercially reasonable terms at the time we are seeking funds. In addition, our ability to borrow funds under our senior revolving credit facility will depend on our ability to satisfy the financial and non-financial covenants contained in that facility.
Debt Repayment
          During the nine month period ended September 29, 2006, Altra Industrial prepaid approximately $12.5 million of our debt owed to CDPQ on our behalf. Altra Industrial also paid approximately $0.8 million and $0.8 million of interest and prepayment premium, respectively.

(2)  We have quarterly interest requirements due on the 17% CDPQ note. Interest is payable in cash or as paid-in-kind to be accrued against the outstanding principal balance at the discretion of the Company. During the nine months ended September 29, 2006 the Company paid $12.5 million of the 17% CDPQ note.
 
(3)  We have up to $30.0 million of borrowing capacity, through November 2009, under our senior revolving credit facility (including $10.0 million available for use for letters of credit). At September 29, 2006, we had no outstanding borrowings and $2.4 million of outstanding letters of credit under our senior revolving credit facility.
 
(4)  As of September 29, 2006 we had capital lease obligations of $0.2 million in 2006, $0.7 million in 2007, $0.4 million in 2008, $0.3 million in 2009, $0.2 million in 2010 and $0.3 million thereafter.
 
(5)  As of September 29, 2006 we had operating lease obligations of $0.6 million in 2006, $3.0 million in 2007, $1.9 million in 2008, $1.0 million in 2009, $0.6 million in 2010 and $1.5 million thereafter.
          In connection with the Hay Hall Acquisition on February 10, 2006, we issued £33.0 million of 11 1 / 4 % senior notes. Assuming an exchange rate of 1.883 U.S. dollars per U.K. pound sterling as of September 29, 2006, the 11 1 / 4 % senior notes have a principal value of $62.1 million. The principal balance is due in 2013. As of September 29, 2006, we have semi-annual cash interest requirements of $7.0 million payable in each of 2007, 2008, 2009 and 2010 and $17.5 million thereafter.
          In June, 2006, our German subsidiary entered into a mortgage on its building in Heidelberg, Germany, with a local bank. The mortgage has a principal of 2.0 million, an interest rate of 5.75% and is payable in monthly installments over 15 years.
          We have cash funding requirements associated with our pension plan. As of September 29, 2006, these requirements were estimated to be $0.6 million during the remainder of 2006, $3.6 million in 2007, $2.5 million in 2008 and $1.9 million annually thereafter until 2011.
Off-Balance Sheet Arrangements
          We do not have any off-balance sheet arrangements that provide liquidity, capital resources, market or credit risk support that expose us to any liability that is not reflected in our combined financial statements.
Stock-based Compensation
          We established the 2004 Equity Incentive Plan that provides for various forms of stock based compensation to our officers and senior level employees. We account for grants under this plan in accordance with the provisions of SFAS No. 123(R). As of September 29, 2006, we had 3,345,511 shares of unvested restricted stock (not giving effect to the two for one reverse stock split). The remaining compensation cost to be recognized through 2011 is $4.8 million. Based on the initial public offering price of $15.00 per share, the midpoint of the range and taking into account the two for one reverse stock split, the intrinsic value of these awards as of September 29, 2006 was $30.1 million, of which $5.0 million related to vested shares and $25.1 million related to unvested shares.
Income Taxes
          We are subject to taxation in multiple jurisdictions throughout the world. Our effective tax rate and tax liability will be affected by a number of factors, such as the amount of taxable income in particular jurisdictions, the tax rates in such jurisdictions, tax treaties between jurisdictions, the extent to which we transfer funds between jurisdictions and repatriate income, and changes in law. Generally, the tax liability for each legal entity is determined either (a) on a non-consolidated and non-combined basis or (b) on a consolidated and combined basis only with other eligible entities subject to tax in the same jurisdiction, in either case without regard to the taxable losses of non-consolidated and non-combined

affiliated entities. As a result, we may pay income taxes to some jurisdictions even though on an overall basis we incur a net loss for the period.
          We have completed an analysis of the American Jobs Creation Act that was passed by both the U.S. House of Representatives and Senate and signed by the President in October 2005. The Act provides a deduction that has the effect of reducing our tax rate and will be phased in over the next five years. As of the nine months ended September 29, 2006, there is no impact on our tax rate from the American Jobs Creation Act.
Critical Accounting Policies
          The methods, estimates and judgments we use in applying our critical accounting policies have a significant impact on the results we report in our financial statements. We evaluate our estimates and judgments on an on-going basis. Our estimates are based upon historical experience and assumptions that we believe are reasonable under the circumstances. Our experience and assumptions form the basis for our judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may vary from what our management anticipates and different assumptions or estimates about the future could change our reported results.
          We believe the following accounting policies are the most critical in that they are important to the financial statements and they require the most difficult, subjective or complex judgments in the preparation of the financial statements.
          Revenue Recognition. Sales and related cost of sales are recorded upon transfer of the title of the product and risk of loss, which occurs upon shipment to the customer, based on the invoice price less allowances for sales returns, cash discounts, and other deductions as required under GAAP. Collection is reasonably consistent with internal policy as determined through an evaluation of each customer’s ability to pay.
          Inventory. We value raw materials, work-in -progress and finished goods produced since inception at the lower of cost or market, as determined on a first-in, first-out (FIFO) basis. We periodically review the carrying value of the inventory and have at times determined that a certain portion of our inventories are excess or obsolete. In those cases, we write down the value of those inventories to their net realizable value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required.
          Retirement Benefits. Pension obligations and other post retirement benefits are actuarially determined and are affected by several assumptions, including the discount rate, assumed annual rates of return on plan assets, and per capita cost of covered health care benefits. Changes in discount rate and differences from actual results for each assumption will affect the amounts of pension expense and other post retirement expense recognized in future periods.
          Goodwill and Intangible Assets. Intangible assets of our Predecessor consisted of goodwill, which represented the excess of the purchase price paid over the fair value of the net assets acquired. In connection with the PTH Acquisition, intangible assets were identified and recorded at their fair value, in accordance with Statement of Financial Accounting Standards, or SFAS No. 141, Business Combinations. We recorded intangible assets for customer relationships, trade names and trademarks, product technology and patents, and goodwill. In valuing the customer relationships, trade names and trademarks and product technology intangible assets, we utilized variations of the income approach. The income approach was considered the most appropriate valuation technique because the inherent value of these assets is their ability to generate current and future income. The income approach relies on historical financial and qualitative information, as well as assumptions and estimates for projected financial information. Projected information is subject to risk if our estimates are incorrect. The most significant estimate relates to our projected revenues. If we do not meet the projected revenues used in the valuation calculations then the intangible assets could be impaired. In determining the value of customer relationships, we reviewed historical customer attrition rates which were determined to be approximately 5% per year. Most of our customers tend to be long-term customers

with very little turnover. While we do not typically have long-term contracts with customers, we have established long-term relationships with customers which make it extremely difficult for competitors to displace us. Additionally, we assessed historical revenue growth within our industry and customers’ industries in determining the value of customer relationships. The value of our customer relationships intangible asset could become impaired if future results differ significantly from any of the underlying assumptions. This could include a higher customer attrition rate or a change in industry trends such as the use of long-term contracts which we may not be able to obtain successfully. Customer relationships and product technology and patents are considered finite-lived assets, with estimated lives of 12 years and 8 years, respectively. The estimated lives were determined by calculating the number of years necessary to obtain 95% of the value of the discounted cash flows of the respective intangible asset. Goodwill and trade names and trademarks are considered indefinite lived assets. Trade names and trademarks were determined to be indefinite lived assets based on the criteria stated in paragraph 11 in SFAS No. 142, Goodwill and Other Intangible Assets. Other intangible assets include trade names and trademarks that identify us and differentiate us from competitors, and therefore competition does not limit the useful life of these assets. All of our brands have been in existence for over 50 years and therefore are not susceptible to obsolescence risk. Additionally, we believe that our trade names and trademarks will continue to generate product sales for an indefinite period. All indefinite lived intangible assets are reviewed at least annually to determine if an impairment exists. An impairment could be triggered by a loss of a major customer, discontinuation of a product line, or a change in any of the underlying assumptions utilized in estimating the value of the intangible assets. If an impairment is identified it will be recognized in that period.
          In accordance with SFAS No. 142, we will assess the fair value of our reporting units for impairment of intangible assets based upon a discounted cash flow methodology. Estimated future cash flows are based upon historical results and current market projections, discounted at a market comparable rate. If the carrying amount of the reporting unit exceeds the estimated fair value determined using the discounted cash flow calculation, goodwill impairment may be present. We would evaluate impairment losses based upon the fair value of the underlying assets and liabilities of the reporting unit, including any unrecognized intangible assets, and estimate the implied fair value of the intangible asset. An impairment loss would be recognized to the extent that a reporting unit’s recorded value of the intangible asset exceeded its calculated fair value.
          We have allocated goodwill and intangible assets arising from the application of purchase accounting for our Predecessor and Kilian acquisitions, and have allocated these assets across our reporting units. We evaluated our intangible assets at the reporting unit level at December 31, 2005 and found no evidence of impairment at that date. If the book value of a reporting unit exceeds its fair value, the implied fair value of goodwill is compared with the carrying amount of goodwill. If the carrying amount of goodwill exceeds the implied fair value, an impairment loss is recorded in an amount equal to that excess. The fair value of a reporting unit is estimated using the discounted cash flow approach, and is dependent on estimates and judgments related to future cash flows and discount rates. If the actual cash flows differ significantly from the estimates used by management, we may be required to record an impairment charge to write down the goodwill to its realizable value.
          Long-lived Assets. Long-lived assets are reviewed for impairment when events or circumstances indicate that the carrying amount of a long-lived asset may not be recoverable and for all assets to be disposed. Long-lived assets held for use are reviewed for impairment by comparing the carrying amount of an asset to the undiscounted future cash flows expected to be generated by the asset over its remaining useful life. If an asset is considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds its fair value, and is charged to results of operations at that time. Assets to be disposed of are reported at the lower of the carrying amounts or fair value less cost to sell. Our management determines fair value using discounted future cash flow analysis. Determining market values based on discounted cash flows requires our management to make significant estimates and assumptions, including long-term projections of cash flows, market conditions and appropriate discount rates.

          Income Taxes. We record income taxes using the asset and liability method. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective income tax bases, and operating loss and tax credit carryforwards. We evaluate the realizability of our net deferred tax assets and assess the need for a valuation allowance on a quarterly basis. The future benefit to be derived from our deferred tax assets is dependent upon our ability to generate sufficient future taxable income to realize the assets. We record a valuation allowance to reduce our net deferred tax assets to the amount that may be more likely than not to be realized. To the extent we establish a valuation allowance, an expense will be recorded within the provision for income taxes line on the statement of operations. In periods subsequent to establishing a valuation allowance, if we were to determine that we would be able to realize our net deferred tax assets in excess of our net recorded amount, an adjustment to the valuation allowance would be recorded as a reduction to income tax expense in the period such determination was made.
Recently Issued Accounting Pronouncements
          In May 2005, the FASB issued Statement of Financial Accounting Standards No. 154, (“Accounting Changes and Error Corrections, a replacement of APB Opinion No. 20, Accounting Changes and FASB Statement No. 3, Reporting Accounting Changes in Interim Financial Statements”)(“SFAS 154”). SFAS 154 provides guidance on the accounting for and reporting of accounting changes and error corrections. It establishes, unless impracticable, retrospective application as the required method for reporting a change in accounting principle in the absence of explicit transition requirements specific to the newly adopted accounting principle. SFAS 154 also provides guidance for determining whether retrospective application of a change in accounting principle is impracticable and for reporting a change when retrospective application is impracticable. The provisions of this Statement are effective for accounting changes and corrections of errors made in fiscal periods beginning after December 15, 2005. The adoption of the provisions of SFAS 154 is not expected to have a material impact on the Company’s financial position or results of operations.
          In November 2004, the FASB issued SFAS No. 151, “Inventory Costs, an amendment of ARB No. 43, Chapter 4” . SFAS No. 151, which is effective for the Company beginning January 1, 2006, SFAS No. 151 clarifies the accounting for abnormal amounts of idle facility expense, freight, handling costs, and wasted material (spoilage) so that those items are recognized as current-period charges. This statement also requires the allocation of fixed production overhead costs based on the normal capacity of the production facilities regardless of the actual use of the facility. The Company does not believe that this statement will have any material impact on the Company’s financial position or results of operations.
          In June 2006, the FASB issued FASB Interpretation No. FIN 48, or FIN 48, Accounting for Uncertainty in Income Taxes — An Interpretation of FASB Statement No. 109 , which prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN 48 will be effective for fiscal years beginning after December 15, 2006. We have not yet completed our evaluation of the impact of adoption on our financial position or results of operations.
          In September 2006, the Securities and Exchange Commission (“SEC”) issued Staff Accounting Bulletin (“SAB”) No. 108 regarding the process of quantifying financial statement misstatements. SAB No. 108 states that registrants should use both a balance sheet approach and an income statement approach when quantifying and evaluating the materiality of a misstatement. The interpretations in SAB No. 108 contain guidance on correcting errors under the dual approach as well as provide transition guidance for correcting errors. This interpretation does not change the requirements within SFAS No. 154, “Accounting Changes and Error Corrections-a replacement of APB No. 20 and FASB Statement No. 3,” for the correction of an error on financial statements. SAB No. 108 is effective for annual financial statements covering the first fiscal year ending after November 15, 2006, The Company does not expect the effect to be material.

          In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements.” This standard defines fair value, establishes a framework for measuring fair value in accounting principles generally accepted in the United States of America, and expands disclosure about fair value measurements. This pronouncement applies under other accounting standards that require or permit fair value measurements. Accordingly, this statement does not require any new fair value measurement. This statement is effective for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The Company does not expect the effect to be material.
          In September 2006, the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans — an amendment of FASB Statements No. 87, 88, 106, and 132(R).” This pronouncement requires an employer to recognize the overfunded or underfunded status of a defined benefit postretirement plan (other than a multiemployer plan) as an asset or liability on its statement of financial position. SFAS No. 158 also requires an employer to recognize changes in that funded status in the year in which the changes occur through comprehensive income. In addition, this statement requires an employer to measure the funded status of a plan as of the date of its year-end statement of financial position, with limited exceptions. SFAS No. 158 is effective for fiscal years ending after December 15, 2006. The Company has not yet completed its evaluation of the impact of adoption on the Company’s financial position or results of operations.
Qualitative and Quantitative Information about Market Risk
          We are exposed to various market risk factors such as fluctuating interest rates and changes in foreign currency rates. At present, we do not utilize derivative instruments to manage this risk.
Foreign Currency Exchange Rate Risk
          Currency translation. The results of operations of our foreign subsidiaries are translated into U.S. dollars at the average exchange rates for each period concerned. The balance sheets of foreign subsidiaries are translated into U.S. dollars at the exchange rates in effect at the end of each period. Any adjustments resulting from the translation are recorded as other comprehensive income. As of December 31, 2005 and September 29, 2006, the aggregate total assets (based on book value) of foreign subsidiaries were $74.6 million and $137.0 million, respectively, representing approximately 25.1% and 36.7%, respectively, of our total assets (based on book value). Our foreign currency exchange rate exposure is primarily with respect to the Euro and British pounds sterling. The approximate exchange rates in effect at December 31, 2005 and September 29, 2006 were $1.19 and $1.27, respectively to the Euro. The approximate exchange rates in effect at December 31, 2005 and September 29, 2006 were $1.74 and $1.88, respectively to the British Pound Sterling. The result of a hypothetical 10% strengthening of the U.S. dollar against the Euro and British Pound Sterling would result in a decrease in the book value of the aggregate total assets of foreign subsidiaries of approximately $13.7 million as of September 29, 2006. The result of a hypothetical 10% strengthening of the U.S. dollar against the Euro and British Pound Sterling would result in a decrease in net income of approximately $0.6 million for the nine months ended September 29, 2006.
          Currency transaction exposure. Currency transaction exposure arises where actual sales and purchases are made by a business or company in a currency other than its own functional currency. Any transactional differences at an international location are accounted for on a monthly basis.
Interest rate risk
          We are subject to market exposure to changes in interest rates based on our financing activities. This exposure relates to borrowings under our senior revolving credit facility that are payable at prime rate plus 1.25% in the case of prime rate loans, or LIBOR rate plus 2.50%, in the case of LIBOR rate loans. As of September 29, 2006, we had no outstanding borrowings and $2.4 million of outstanding letters of credit under our senior revolving credit facility. Because we have no outstanding debt under our senior

52

revolving credit facility, a hypothetical change in interest rates of 1% would not have a material effect on our near-term financial condition or results of operations. See “Description of Indebtedness.”
The Sarbanes-Oxley Act of 2002 and Material Weakness in Internal Control
          In connection with their audit of our fiscal 2005 financial statements, our independent auditors expressed concerns that as of the date of their opinion we were unable to report accurate financial information in a timely manner due to resource limitations of our financial staffing. Based upon the timely financial reporting required of a public company, the outside auditors informed senior management and the Audit Committee of the board of directors that they believe this is a material weakness in our internal controls. We are actively taking steps to address this material weakness. These steps include the recent hiring of a Director of Internal Audit and an SEC Manager and our prior hiring of a Corporate Controller, Director of Taxation and a Corporate Accountant. We believe that with the addition of these resources we should be able to deliver financial information on a timely basis.

BUSINESS
Our Company
          We are a leading global designer, producer and marketer of a wide range of MPT and motion control products serving customers in a diverse group of industries, including energy, general industrial, material handling, mining, transportation and turf and garden. Our product portfolio includes industrial clutches and brakes, enclosed gear drives, open gearing, couplings, engineered bearing assemblies, linear components and other related products. Our products are used in a wide variety of high-volume manufacturing processes, where the reliability and accuracy of our products are critical in both avoiding costly down time and enhancing the overall efficiency of manufacturing operations. Our products are also used in non-manufacturing applications where product quality and reliability are especially critical, such as clutches and brakes for elevators and residential and commercial lawnmowers. For the nine months ended September 29, 2006, we had net sales of $347.5 million, net income of $10.7 million and EBITDA of $46.9 million.
          We market our products under well recognized and established brand names, including Warner Electric, Boston Gear, Kilian Manufacturing, Nuttall Gear, Ameridrives, Wichita Clutch, Formsprag Clutch, Bibby Transmissions, Stieber, Matrix International, Inertia Dynamics, Twiflex Limited, Industrial Clutch, Huco Dynatork, Marland Clutch, Delroyd Worm Gear, Bear Linear and Saftek. Most of these brands have been in existence for over 50 years. According to the most recently published Motion Systems Design magazine survey, our brands, when taken together with brands in the same product category, have achieved the number one or number two position in terms of brand awareness in their respective product categories. We believe over 50% of our revenues for the nine months ended September 29, 2006 were generated from key products where we have the number one or number two market share position in the markets we serve.
          Our products are either incorporated into products sold by OEMs, sold to end users directly or sold through industrial distributors. We sell our products in over 70 countries to over 700 direct OEM customers and over 3,000 distributor outlets through our global sales and marketing network. Substantially all of our products are moving, wearing components which are consumed in use. Due to the complexity of many of our customers’ manufacturing operations and the high cost of process failure, our customers have demonstrated a strong preference to replace their worn Altra brand products with new Altra products. This replacement dynamic drives recurring replacement sales, resulting in aftermarket revenue that we estimate accounted for approximately 43% of our revenues for the nine months ended September 29, 2006.
          We are led by a highly experienced management team with over 425 years of cumulative industrial business experience and an average of 14 years with our companies. Our management team has established a proven track record of execution, successfully completing and integrating major strategic acquisitions and delivering significant growth in both revenues and profits. We employ a comprehensive business process called the ABS, which focuses on eliminating inefficiencies from every business process to improve quality, delivery and cost.
Our Industry
          Based on industry data supplied by Penton Information Services, we estimate that industrial power transmission products generated sales in the United States of approximately $30.3 billion in 2005. These products are used to generate, transmit, control and transform mechanical energy. The industrial power transmission industry can be divided into three areas: MPT products; motors and generators; and adjustable speed drives. We compete primarily in the MPT area which, based on industry data, we estimate was a $15.7 billion market in the United States in 2005.
          The global MPT market is highly fragmented, with over 1,000 small manufacturers. While smaller companies tend to focus on regional niche markets with narrow product lines, larger companies that each generate annual sales over $100 million offer a much broader range of products and have global capabilities. The industry’s customer base is broadly diversified across many sectors of the economy and

54


Table of Contents

typically places a premium on factors such as quality, reliability, availability and design and application engineering support. We believe the most successful industry participants are those that leverage their distribution network, their products’ reputations for quality and reliability and their service and technical support capabilities to maintain attractive margins on products and gain market share.
Our Strengths
          Leading Market Shares and Brand Names. We believe that we hold the number one or number two market position in key products across several of our core platforms. For example, under a report published by the Global Industry Analysts, Inc., we are one of the leading manufacturers of industrial clutches and brakes in the world. We believe that over 50% of our sales are derived from products where we hold the number one or number two share of in the markets we serve. Our brands, most of which have been in existence for more than 50 years, are widely known in the MPT product markets. We believe over 50% of our sales are generated from products where, according to the most recently published Motion Systems Design magazine survey, our brands on a consolidated basis have the number one or number two brand recognition in the markets we serve.
          Large Installed Base and Diversified OEM Customers Supporting Aftermarket Sales. With a history dating back to 1877 with the formation of Boston Gear, we believe we benefit from one of the largest installed customers bases in the industry. Given the moving, wearing nature of our products, which require regular replacement, our large installed base of products with a diversified group of end user customers, generates significant aftermarket replacement demand which creates a recurring revenue stream. Many of our products serve critical functions, where the cost of product failure would substantially exceed any potential cost reduction benefits from using cheaper, less proven parts. This end user preference and consistently recurring replacement demand in turn help to stabilize our revenue base from the cyclical nature of the broader economy. For the nine months ended September 29, 2006 we estimate that approximately 43% of our revenues were derived from aftermarket sales.
          Diversified End-Markets. Our revenue base has balanced exposure across a diverse mix of end user industries, including energy, general industrial, material handling, mining, transportation and turf and garden, which helps mitigate the impact of business and economic cycles. No single industry represented more than 10% of our total sales. In addition, for the nine months ended September 29, 2006, approximately 29% of our sales were from outside North America. Our geographic diversification is further enhanced because some of our products sold into the North American market are ultimately exported into international markets as part of the final product sold by the customer.
          Strong Relationship with Distributors and OEMs. We have over 700 direct OEM customers and enjoy established, long-term relationships with the leading MPT industrial distributors, critical factors that contribute to our high base of recurring aftermarket revenues. We sell our products through more than 3,000 distributor outlets worldwide. We believe our scale, end user preference and expansive product line make our product portfolio attractive to both large and multi-branch distributors, as well as regional and independent distributors in our industry.
          Experienced, High-Caliber Management Team. We are led by a highly experienced management team with over 425 years of cumulative industrial business experience and an average of 14 years with our companies. Our CEO, Michael Hurt, has over 39 years of experience in the MPT industry, while COO Carl Christenson has over 25 years of experience. Our management team has established a proven track record of execution, successfully completing and integrating major strategic acquisitions and delivering significant growth and profitability.
          The Altra Business System. We benefit from an established culture of lean management emphasizing quality, delivery and cost through the ABS. ABS is at the core of our performance-driven culture and drives both our strategic development and operational improvements. We estimate that in the period from January 1, 2005 through June 30, 2006, ABS has enabled us to achieve savings of over $5 million through various initiatives, including: (a)  set-up time reduction and productivity improvement, (b) finished goods inventory reduction, (c) improved quality and reduction of internal scrap, (d) on-time

55


Table of Contents

delivery improvement, (e) utilizing value stream mapping to minimize work in process inventory and increase productivity and (f) headcount reductions. We believe these initiatives will continue to provide us with recurring annual savings. We intend to continue to aggressively implement operational excellence initiatives by utilizing the ABS tools throughout our company.
          Proven Product Development Capabilities. Our extensive application engineering know-how drives both new and repeat sales. Our broad portfolio of products, knowledge and expertise across various MPT applications allows us to provide our customers customized solutions to meet their specific needs. We are highly focused on developing new products in response to customer requirements. We employ approximately 170 non-manufacturing engineers involved with product development, research and development, test and technical customer support. Recent new product development examples include the Foot/ Deck Mount Kopper Kool Brake which was designed for very high heat dissipation in extremely rugged tensioning applications such as drawworks for oil and gas wells and anchoring systems for on-shore and off-shore drilling platforms.
Our Business Strategy
          We intend to continue to increase our sales through organic growth, expand our geographic reach and product offering through strategic acquisitions and improve our profitability through cost reduction initiatives. We seek to achieve these objectives through the following strategies:
  Leverage Our Sales and Distribution Network. We intend to continue to leverage our relationships with our distributors to gain shelf space, further integrate our recently acquired brands with our core brands and sell new products. In addition, we intend to continue to actively pursue new OEM opportunities with innovative and cost-effective product designs and applications to help maintain and grow our aftermarket revenues. For example, in 2002 we launched a new product in the wrap spring category. Despite established competition within this particular category, we were able to quickly penetrate the market and we expect to exceed 15% in global market share in 2006 due to the strength of our Warner Electric brand. We seek to capitalize on customer brand preference for our products to generate pull-through aftermarket demand from our distribution channel. We believe this strategy also allows our distributors to achieve high profit margins, further enhancing our preferred position with them.
 
  Focus our Strategic Marketing on New Growth Opportunities. We intend to expand our emphasis on strategic marketing to focus on new growth opportunities in key end user markets. Through a systematic process that leverages our core brands and products, we seek to identify attractive markets and product niches, collect customer and market data, identify market drivers, tailor product and service solutions to specific market and customer requirements and deploy resources to gain market share and drive future sales growth.
 
  Accelerate New Product and Technology Development. We are highly focused on driving new product development across our business in response to customer needs in various markets. Through our strategic marketing efforts, we continually gain market and customer intelligence, which feeds new product and technology development initiatives that are designed to address particular needs or problems customers identify. This focus has allowed us to respond quickly to new market opportunities.
  Recent new product development examples include the Foot/ Deck Mount Kopper Kool Brake, a new clutch brake design which significantly extends product life and can dramatically reduce blade stop time on commercial and residential lawn tractors, a new magnetic particle clutch designed to solve a number of long-standing performance issues on soft-drink bottle capping applications, and the RA10 speed reducer, designed for use in the rapidly growing market for armor-fitted military vehicles used by the US military. In total, we expect new products developed by us during the past three years to generate approximately $40 million in revenues in 2006.

  Capitalize on Growth and Sourcing Opportunities in the Asia-Pacific Market. We intend to leverage our established sales offices in China, Taiwan and Singapore, as well as add representation in Japan and South Korea. We also intend to expand our manufacturing presence in Asia beyond our current plant in Shenzhen, China, to increase sales in the high-growth Asia-Pacific region. This region also offers opportunities for low-cost country sourcing of raw materials. During 2005, we sourced approximately 12% of our purchases from low-cost countries, resulting in average cost reductions of approximately 40% for these products. Within the next five years, we intend to utilize our sourcing office in Shanghai to significantly increase our current level of low-cost country sourced purchases. We may also consider opportunities to outsource some of our production from North American and Western European locations to Asia.
 
  Continue to Improve Operational and Manufacturing Efficiencies through ABS. We believe we can continue to improve profitability through cost control, overhead rationalization, global process optimization, continued implementation of lean manufacturing techniques and strategic pricing initiatives. Our operating plan, based on manufacturing centers of excellence, provides additional opportunities to reduce costs by sharing best practices across geographies and business lines and by consolidating purchasing processes. We have implemented these principles with our recent acquisitions of Hay Hall and Bear Linear and intend to apply such principles to future acquisitions.
 
  Pursue Strategic Acquisitions that Complement our Strong Platform. With our extensive MPT and motion control products, our strong customer and distributor relationships and our know-how in implementing lean enterprise initiatives through ABS, we have an ideal platform for acquiring and successfully integrating related businesses, as evidenced through our acquisition and integration of Hay Hall and Bear Linear. Management believes that there may be a number of attractive potential acquisition candidates in the future, in part due to the fragmented nature of the industry. We plan to continue our disciplined pursuit of strategic acquisitions to accelerate our growth, enhance our industry leadership and create value.

          We produce and market a wide variety of MPT products. Our product portfolio includes industrial clutches and brakes, open and enclosed gearing, couplings, engineered bearing assemblies and other related power transmission components which are sold across a wide variety of industries. Our products benefit from our industry leading brand names including Warner Electric, Boston Gear, Kilian Manufacturing, Nuttall Gear, Ameridrives, Wichita Clutch, Formsprag Clutch, Bibby Transmissions, Stieber, Matrix International, Inertia Dynamics, Twiflex Limited, Industrial Clutch, Huco Dynatork, Marland Clutch, Delroyd Worm Gear, Bear Linear and Saftek. Our products serve a wide variety of end markets including aerospace, energy, food processing, general industrial, material handling, mining, petrochemical, transportation and turf and garden. We primarily sell our products to OEMs and through long-standing relationships with the industry’s leading industrial distributors such as Motion Industries, Applied Industrial Technologies, Kaman Industrial Technologies and W.W. Grainger. The following discussion of our products does not include detailed product category revenue because such information is not individually tracked by our financial reporting system and is not separately reported by our general purpose financial statements. Conducting a detailed product revenue internal assessment and audit would involve unreasonable effort and expense as revenue information by product line is not available. We maintain sales information by operating facility, but do not maintain any accounting sales data by product line.

Table of Contents

          Our continued investment in new product development is intended to help drive customer growth as we address key customer needs.
Sales and Marketing
          We sell our products in over 70 countries to over 700 direct OEM customers and over 3,000 distributor outlets. We offer our products through our direct sales force comprised of 101 company-employed sales associates as well as independent sales representatives. Our worldwide sales and distribution presence enables us to provide timely and responsive support and service to our customers, many of which operate globally, and to capitalize on growth opportunities in both developed and emerging markets around the world.
          We employ an integrated sales and marketing strategy concentrated on both key industries and individual product lines. We believe this dual vertical market and horizontal product approach distinguishes us in the marketplace allowing us to quickly identify trends and customer growth opportunities and deploy resources accordingly. Within our key industries, we market to OEMs, encouraging them to incorporate our products into their equipment designs, to distributors and to end users, helping to foster brand preference. With this strategy, we are able to leverage our industry experience and product breadth to sell MPT and motion control solutions for a host of industrial applications.
Distribution
          Our MPT components are either incorporated into end products sold by OEMs or sold through industrial distributors as aftermarket products to end users and smaller OEMs. We operate a geographically diversified business. For the nine months ended September 29, 2006, 71.2% of our net sales were derived from customers in North America, 20.8% from customers in Europe and 8.0% from customers in Asia and the rest of the world. Our global customer base is served by an extensive global sales network comprised of our sales staff as well as our network of over 3,000 distributor outlets.
          Rather than serving as passive conduits for delivery of product, our industrial distributors are active participants in influencing product purchasing decisions in the MPT industry. In addition, distributors play a critical role through stocking inventory of our products, which affects the accessibility of our products to aftermarket buyers. It is for this reason that distributor partner relationships are so critical to the success of the business. We enjoy strong established relationships with the leading distributors as well as a broad, diversified base of specialty and regional distributors.
Competition
          We operate in highly fragmented and very competitive markets within the MPT market. Some of our competitors have achieved substantially more market penetration in certain of the markets in which we operate, such as helical gear drives and couplings, and some of our competitors are larger than us and have greater financial and other resources. In particular, we compete with Emerson Power Transmission Manufacturing, L.P., Regal Beloit Corporation and Rockwell Automation. In addition, with respect to certain of our products, we compete with divisions of our OEM customers. Competition in our business lines is based on a number of considerations including quality, reliability, pricing, availability and design and application engineering support. Our customers increasingly demand a broad product range and we must continue to develop our expertise in order to manufacture and market these products successfully. To remain competitive, we will need to invest regularly in manufacturing, customer service and support, marketing, sales, research and development and intellectual property protection. We may have to adjust the prices of some of our products to stay competitive. In addition, some of our larger, more sophisticated customers are attempting to reduce the number of vendors from which they purchase in order to increase their efficiency. There is substantial and continuing pressure on major OEMs and larger distributors to reduce costs, including the cost of products purchased from outside suppliers such as us. As a result of cost pressures from our customers, our ability to compete depends in part on our ability to generate

60

production cost savings and, in turn, find reliable, cost-effective outside component suppliers or manufacture our products.
Intellectual Property
          We rely on a combination of patents, trademarks, copyright and trade secret laws in the United States and other jurisdictions, as well as employee and third-party non-disclosure agreements, license arrangements and domain name registrations to protect our intellectual property. We sell our products under a number of registered and unregistered trademarks, which we believe are widely recognized in the MPT industry. With the exception of Boston Gear and Warner Electric, we do not believe any single patent, trademark or trade name is material to our business as a whole. Any issued patents that cover our proprietary technology and any of our other intellectual property rights may not provide us with adequate protection or be commercially beneficial to us and, if applied for, may not be issued. The issuance of a patent is not conclusive as to its validity or its enforceability. Competitors may also be able to design around our patents. If we are unable to protect our patented technologies, our competitors could commercialize technologies or products which are substantially similar to ours.
          With respect to proprietary know-how, we rely on trade secret laws in the United States and other jurisdictions and on confidentiality agreements. Monitoring the unauthorized use of our technology is difficult and the steps we have taken may not prevent unauthorized use of our technology. The disclosure or misappropriation of our intellectual property could harm our ability to protect our rights and our competitive position.
          Some of our registered and unregistered trademarks include: Warner Electric, Boston Gear, Kilian Manufacturing, Nuttall Gear, Ameridrives, Wichita Clutch, Formsprag Clutch, Bibby Transmissions, Stieber, Matrix International, Inertia Dynamics, Twiflex Limited, Industrial Clutch, Huco Dynatork, Marland Clutch, Delroyd Worm Gear, Bear Linear and Saftek.
Backlog
          Our backlog of unshipped orders was $133.2 million at September 29, 2006 and $102.0 million and $90.6 million at December 31, 2005 and December 31, 2004, respectively.
Employees
          As of September 29, 2006, we had approximately 2,600 full-time employees, of whom approximately 57% were located in the United States, 29% in Europe, and 14% in Asia. Approximately 21% of our full-time factory North American employees are represented by labor unions. In addition, approximately half of our employees in our facility in Scotland are represented by a labor union. The four U.S. collective bargaining agreements to which we are a party will expire on August 10, 2007, September 19, 2007, June 2, 2008 and February 1, 2009, while our agreement in Scotland expires on March 31, 2007. Two of the four U.S. collective bargaining agreements contain provisions for additional, potentially significant lump-sum severance payments to all employees covered by the agreements who are terminated as the result of a plant closing. See “Risk Factors — Risks Related to our Business — We may be subjected to work stoppages at our facilities, or our customers may be subjected to work stoppages, which could seriously impact the profitability of our business.”
          The remainder of our European facilities have employees who are generally represented by local and national social works councils which are common in Europe. Social works councils meet with employer industry associations every two to three years to discuss employee wages and working conditions. Our facilities in France and Germany often participate in such discussions and adhere to any agreements reached.

Suppliers and Raw Materials
          We obtain raw materials, component parts and supplies from a variety of sources, generally from more than one supplier. Our suppliers and sources of raw materials are based in both the United States

62


Table of Contents

and other countries and we believe that our sources of raw materials are adequate for our needs for the foreseeable future. We do not believe the loss of any one supplier would have a material adverse effect on our business or result of operations. Our principal raw materials are steel, castings and copper. We generally purchase our materials on the open market, where certain commodities such as steel and copper have increased in price significantly in recent years. We have not experienced any significant shortage of our key materials and have not historically engaged in hedging transactions for commodity suppliers.
Regulation
          We are subject to a variety of government laws and regulations that apply to companies engaged in international operations. These include compliance with the Foreign Corrupt Practices Act, U.S. Department of Commerce export controls, local government regulations and procurement policies and practices (including regulations relating to import-export control, investments, exchange controls and repatriation of earnings). We maintain controls and procedures to comply with laws and regulations associated with our international operations. In the event we are unable to remain compliant with such laws and regulations, our business may be adversely affected.
Environmental and Health and Safety Matters
          We are subject to a variety of federal, state, local, foreign and provincial environmental laws and regulations, including those governing the discharge of pollutants into the air or water, the management and disposal of hazardous substances and wastes and the responsibility to investigate and cleanup contaminated sites that are or were owned, leased, operated or used by us or our predecessors. Some of these laws and regulations require us to obtain permits, which contain terms and conditions that impose limitations on our ability to emit and discharge hazardous materials into the environment and periodically may be subject to modification, renewal and revocation by issuing authorities. Fines and penalties may be imposed for non-compliance with applicable environmental laws and regulations and the failure to have or to comply with the terms and conditions of required permits. From time to time our operations may not be in full compliance with the terms and conditions of our permits. We periodically review our procedures and policies for compliance with environmental laws and requirements. We believe that our operations generally are in material compliance with applicable environmental laws and requirements and that any non-compliance would not be expected to result in us incurring material liability or cost to achieve compliance. Historically, the costs of achieving and maintaining compliance with environmental laws and requirements have not been material.
          Certain environmental laws in the United States, such as the federal Superfund law and similar state laws, impose liability for the cost of investigation or remediation of contaminated sites upon the current or, in some cases, the former site owners or operators and upon parties who arranged for the disposal of wastes or transported or sent those wastes to an off-site facility for treatment or disposal, regardless of when the release of hazardous substances occurred or the lawfulness of the activities giving rise to the release. Such liability can be imposed without regard to fault and, under certain circumstances, can be joint and several, resulting in one party being held responsible for the entire obligation. As a practical matter, however, the costs of investigation and remediation generally are allocated among the viable responsible parties on some form of equitable basis. Liability also may include damages to natural resources. We are not listed as a potentially responsible party in connection with any sites we currently or formerly owned or operated or any off-site waste disposal facility. There is contamination at some of our current facilities, primarily related to historical operations at those sites, for which we could be liable under these environmental laws. The potential for contamination exists due to historic activities at our other current or former sites. We currently are not undertaking any remediation or investigations and our costs or liability in connection with potential contamination conditions at our facilities cannot be predicted at this time because the potential existence of contamination has not been investigated or not enough is known about the environmental conditions or likely remedial requirements. Currently, other parties with contractual liability are addressing or have plans or obligations to address those contamination conditions that may pose a material risk to human health, safety or the environment. We are being indemnified by

63


Table of Contents

third parties subject to certain caps or limitations on the indemnification, for certain environmental costs and liabilities. Accordingly, based on the indemnification and the experience with similar sites of the environmental consultants who we have hired, we do not expect such costs and liabilities to have a material adverse effect on our business, operations or earnings.
Legal Proceedings
          We are, from time to time, party to various legal proceedings arising out of our business. These proceedings primarily involve commercial claims, product liability claims, intellectual property claims, environmental claims, personal injury claims and workers’ compensation claims. We cannot predict the outcome of these lawsuits, legal proceedings and claims with certainty. Nevertheless, we believe that the outcome of any currently existing proceedings, even if determined adversely, would not have a material adverse effect on our business, financial condition and results of operations.

Compensation Committee Interlocks and Insider Participation
          During our last completed fiscal year, none of our executive officers served on our compensation committee or served on the compensation committee or board of directors of any other company of which any of our directors is an executive officer.
          In January 2005, Mr. Frank Bauchiero, a member of our Compensation Committee, received a one-time consulting fee of $75,000 for certain consulting and advisory services rendered to us in connection with the PTH Acquisition. In addition, Mr. Richard Paterson and Mr. Darren Gold are employees of Genstar Capital, our largest stockholder. Please see “Certain Relationships and Related Transactions” for a description of Genstar Capital’s relationship with us.
Equity Incentive Plan
          In connection with the PTH Acquisition, we adopted an equity incentive plan that permits the grant of restricted stock, stock units, stock appreciation rights, cash, non-qualified stock options and incentive stock options to purchase shares of our common stock. The equity incentive plan was subsequently amended to increase the number of shares of common stock, par value $0.001 per share, that may be issued there under. Currently, the maximum number of shares of our common stock that may be issued under the terms of the equity incentive plan is 3,004,256 and the maximum number of shares that may be subject to “incentive stock options” (within the meaning of Section 422 of the Code) is 1,750,000 shares. A committee appointed by our board of directors administers the equity incentive plan and has discretion to establish the specific terms and conditions for each award. Our employees, consultants and directors are eligible to receive awards under our equity incentive plan. Stock options, stock appreciation rights, restricted stock, stock units and cash awards may constitute performance-based awards in accordance with Section 162(m) of the Code at the discretion of the committee. Any grant of restricted stock under our plan may be subject to vesting requirements, as provided in its applicable award agreement, and will generally vest in five equal annual installments. The committee may provide that any time prior to a change in control, any outstanding stock options, stock appreciation rights, stock units and unvested cash awards shall immediately vest and become exercisable and any restriction on restricted stock awards or stock units shall immediately lapse. In addition, the committee may provide that all awards held by participants who are in our service at the time of the change of control, shall remain exercisable for the remainder of their terms notwithstanding any subsequent termination of a participant’s service. All awards shall be subject to the terms of any agreement effecting a change of control. Other than Mr. Hurt’s grants, upon a participant’s termination of employment (other than for cause), unless the board or committee provides otherwise: (i) any outstanding stock options or stock appreciation rights may be exercised 90 days after termination, to the extent vested, (ii) unvested restricted stock awards and stock units shall expire and (iii) cash awards and performance-based awards shall be forfeited. Under the terms of amendments to his restricted stock agreements, in the event Mr. Hurt’s employment is terminated by the company other than for cause, or terminates for good reason, death or disability all of his unvested restricted stock awards shall vest automatically.

Pension Plan
          Gerald Ferris and Craig Schuele previously participated in the Colfax PT Pension Plan; however, on December 31, 1998, their participation in and benefits accrued under such plan were frozen. Under the provisions of the plan, upon reaching the normal retirement age of 65, Messrs. Ferris and Schuele will receive annual payments of approximately $38,700 and $10,800 respectively. These amounts were determined from a formula set forth in the plan and are based upon (i) a participant’s years of service, (ii) a participant’s compensation at the time the plan was frozen, and (iii) a standard set of benefit percentage multipliers. As part of the PTH Acquisition, we were obligated to assume certain liabilities of the Colfax PT Pension Plan, including such future payments to Messrs. Ferris and Schuele, and established a new plan, the Altra Industrial Motion, Inc. Retirement Plan to do so. Participation in and the benefits under the Altra Industrial Motion Retirement Plan have been frozen at identical levels to the Colfax PT Pension Plan. See “Risk Factors — Risks Relating to Our Business — We face additional costs associated with our post-retirement and post-employment obligations to employees which could have an adverse effect on our financial condition.”
Severance Agreements
          PTH Severance Agreements. We assumed severance agreements with certain executive officers upon the completion of the PTH Acquisition. Each of the severance agreements provided that, subject to the executive’s execution of a general release of claims and the executive’s compliance with certain other restrictive covenants, if the executive was terminated during the first year of employment after the PTH Acquisition by us without “cause” or by the executive for “good reason” (each as defined in the severance agreements), we would pay the executive a severance benefit equal to the executive’s annual base salary as of the closing date for a specified amount of time ranging from nine months to 12 months. If an executive timely elected continuation coverage under our health care and dental plans, subject to the executive’s continued co-payment of the applicable premiums, we would continue to pay our share of the health care and dental premiums during the period of salary continuation. Continuation coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended, would commence after the period of salary continuation. Any severance benefit would cease upon the executive’s obtaining other full-time employment at a rate of pay equal to or greater than 75% of the executive’s base salary at the time of termination of employment.
          During the first quarter of 2005, two executives with severance agreements were terminated. The amount paid by us under the severance agreements was approximately $0.3 million.
          The remaining severance agreements expired on November 30, 2005.
          Transition Agreements. We have entered into transition agreements with four of our executive officers (including Messrs. Ferris, McGowan, Novotny and Schuele). Each of the agreements provides that, subject to the executive’s execution of a general release of claims and the executive’s compliance with certain other restrictive covenants, if the executive is terminated during the first year of employment, after the sale of the company or such executive’s business unit, by us without “cause” or by the executive for “good reason” (each as defined in the transition agreement), we would pay the executive a severance benefit equal to the executive’s annual base salary for a specified amount of time ranging from nine months to 12 months. If an executive timely elected continuation coverage under our health care and dental plans, subject to the executive’s continued co-payment of the applicable premiums, we would continue to pay our share of the health care and dental premiums during the period of salary continuation. Continuation coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended, would commence after the period of salary continuation. Any severance benefit would cease upon the executive’s obtaining other full-time employment.

Option/ SAR Grants in Last Fiscal Year
          There were no option/ SAR grants in 2005.
Employment Agreements and Change of Control Arrangements
          Three of our senior executives, Michael Hurt, Carl Christenson and David Wall, entered into employment agreements with us and Altra Industrial in early January 2005. Mr. Hurt’s employment agreement was subsequently amended in December 2006. Under the terms of his employment agreement, Mr. Hurt has a three-year term, following which the agreement automatically renews for one-year terms unless either party terminates the agreement upon six months prior notice to such renewal date. Under the terms of their respective employment agreements, Messrs. Christenson and Wall have five-year terms. The employment agreements contain usual and customary restrictive covenants, including 12 month non-competition provisions and non-solicitation/no hire of employees or customers provisions, non-disclosure of proprietary information provisions and non-disparagement provisions. In the event of a termination without “cause” or departure for “good reason,” the terminated senior executives are entitled to severance equal to 12 months salary plus an amount equal to their pro-rated bonus for the year of termination. In addition, upon such termination all of Mr. Hurt’s unvested restricted stock received from our 2004 Equity Incentive Plan shall automatically vest. Mr. Hurt, Mr. Christenson and Mr. Wall will receive annual base salaries of $373,000, $275,000 and $230,000, respectively, in 2006 and each is eligible to receive an annual performance bonus of up to 60%, 50% and 40% of their annual base salary, respectively.
          Under the agreements, each senior executive is also eligible to participate in all compensation or employee benefit plans or programs and to receive all benefits and perquisites for which salaried employees of Altra Industrial generally are eligible under any current or future plan or program on the same basis as other senior executives of Altra Industrial.

          Genstar & CDPQ Purchase. In connection with the PTH Acquisition, the Genstar Funds and Caisse de dépôt et placement du Québec, or CDPQ, purchased approximately 26.3 million shares of our preferred stock for approximately $26.3 million.
          The Kilian Transactions. Prior to our organization, the Genstar Funds formed Kilian to facilitate an acquisition of the Kilian Manufacturing Corporation from Timken U.S. Corporation. Michael L. Hurt, our CEO, purchased 5,000 shares of Kilian preferred stock at a price of $100 per share upon its formation. In addition, Mr. Hurt served as CEO of Kilian and received 2,922 shares of Kilian restricted common stock pursuant to Kilian’s equity incentive plan.

          Prior to the consummation of the PTH Acquisition, the Genstar Funds determined that the Kilian and PTH businesses should be combined. Consequently, concurrently with the consummation of the PTH Acquisition, the Genstar Funds, Michael L. Hurt, our CEO, and certain other Kilian investors exchanged all of their Kilian preferred stock, at a value of $8.8 million, for an additional 8.8 million shares of our preferred stock. In addition, members of Kilian’s management who had received a total of 8,767 shares of Kilian restricted common stock, exchanged all such shares for a total of 439,057 shares of our restricted common stock pursuant to our equity incentive plan.

The Kilian preferred stock and restricted common stock we received from these exchanges represented all of the outstanding ownership interests in Kilian.
          Contribution to Altra. All of the cash and Kilian stock we received from such sales of our preferred stock and the exchange of our restricted common stock were contributed to Altra Industrial, and the cash portion thereof provided a portion of the funds necessary to complete the PTH Acquisition.

After the completion of this offering, all outstanding shares of our preferred stock will automatically convert into shares of our common stock on a one share of common stock for every two shares of preferred stock outstanding basis. The Genstar Funds will own 34.6% of our common stock and CDPQ will own 9.3% of our common stock.
Genstar Advisory Services Agreement
          In connection with the PTH Acquisition, we entered into an advisory services agreement with Genstar Capital, L.P., an affiliate of Genstar Management LLC, for management, business strategy, consulting and financial advisory and acquisition related services to be provided to us and our subsidiaries. The agreement provides for the payment to Genstar Capital, L.P. of an annual fee of $1 million (payable quarterly) for advisory and other consulting services. In addition, we pay Genstar Capital LP an advisory fee of 2% of the aggregate consideration relating to any merger, acquisition, disposition or other strategic transactions, as approved by our board of directors, plus reimbursement of out-of-pocket expenses, including legal fees. Upon an initial public offering of our common stock, the agreement provides we will pay Genstar Capital L.P. an advisory fee of $3.0 million in lieu of the 2% advisory fee. Pursuant to the

73

agreement in November 2004 we paid Genstar Capital, L.P. a transaction fee of $4.0 million and an expense reimbursement of $0.4 million upon the consummation of the PTH Acquisition. In addition, in connection with our acquisition of Hay Hall in February 2006, we paid Genstar Capital, L.P. a transaction fee of $1.0 million. The agreement also provides for indemnification of Genstar Capital, L.P. against liabilities and expenses arising out of Genstar’s performance of services under the agreement. Following the completion of this offering and our payment of the $3.0 million fee to Genstar Capital L.P., the advisory services agreement will automatically terminate.
CDPQ Subordinated Notes Investment
          In connection with the PTH Acquisition, CDPQ entered into a note purchase agreement with us, pursuant to which CDPQ purchased $14.0 million of our subordinated notes, to provide a portion of the funds necessary to complete the transaction. The subordinated notes:

We call the right to require us to register the Genstar Securities a demand right, and the resulting registration a demand registration.

The Company’s stockholders who are a party to the agreement, including the Genstar Funds, CDPQ and stockholders who are members of management, can request to participate in, or “piggyback” on, registrations of any of our securities for sale by us. We call this right a piggyback right, and the resulting registration a piggyback registration. The piggyback right applies to any registration other than, among other things, a registration on Form  S-4 or Form  S-8 or in an initial public offering.
Bear Linear Acquisition
          On May 18, 2006, Altra Industrial entered into a purchase agreement with Bear Linear and certain of its members to purchase the business and substantially all of the assets of Bear Linear for $5.0 million. The Company based the value of Bear Linear on a multiple of the estimated future earnings of the business. Bear Linear was founded by its three members in 2001 and manufactured high value-added linear actuators for mobile off-highway and industrial applications. One of the three members of Bear Linear, Robert F. Bauchiero, is the son of one of our directors, Frank E. Bauchiero. The Board of Directors of Altra Industrial unanimously approved the acquisition of Bear Linear which was conducted by arms length negotiations between the parties.

As of October 31, 2006, there were 2,004,256 shares of common stock issued and outstanding (out of 50,000,000 authorized) and 35,500,000 shares of preferred stock issued and outstanding (out of 40,000,000 authorized). As of October 31, 2006, there were fourteen holders of record of our common stock and eighteen holders of record of our preferred stock. All of our outstanding shares of preferred stock will automatically convert into shares of common stock on the effective date of this offering on a one share of common stock for every two shares of preferred stock outstanding basis.
          All of our existing stock is, and the shares of common stock being offered by us in this offering will be, upon payment therefore, validly issued, fully paid and nonassessable. The discussion set forth below describes the most important terms of our capital stock, certificate of incorporation and bylaws as will be in effect upon completion of this offering. Because it is only a summary, this section does not contain all the information that may be important to you. For a complete description you should refer to our certificate of incorporation and bylaws, copies of which will be filed as exhibits to the registration statement of which the prospectus is a part.
Common Stock
          Voting Rights. The holders of our common stock are entitled to one vote per share on all matters submitted for action by the stockholders. There is no provision for cumulative voting with respect to the election of directors. Accordingly, a holder of more than 50% of the shares of our common stock can, if it so chooses, elect all of our directors. In that event, the holders of the remaining shares will not be able to elect any directors.
          Dividend Rights. All shares of our common stock are entitled to share equally in any dividends our board of directors may declare from legally available sources, subject to the terms of any outstanding preferred stock.
          Liquidation Rights. Upon liquidation or dissolution of our company, whether voluntary or involuntary, all shares of our common stock are entitled to share equally in the assets available for distribution to stockholders after payment of all of our prior obligations, including any then-outstanding preferred stock.
          Other Matters. The holders of our common stock have no preemptive or conversion rights, and our common stock is not subject to further calls or assessments by us. There are no redemption or sinking fund provisions applicable to the common stock. All outstanding shares of our common stock, including the common stock offered in this offering, are fully paid and non-assessable.
Preferred Stock
          Our board of directors has the authority to issue preferred stock in one or more classes or series and to fix the designations, powers, preferences and rights, and the qualifications, limitations or restrictions thereof including dividend rights, dividend rates, conversion rights, voting rights, terms of redemption, redemption prices, liquidation preferences and the number of shares constituting any class or series, without further vote or action by the stockholders. The issuance of preferred stock may have the effect of delaying, deferring or preventing a change of control of our company without further action by the stockholders and may adversely affect the voting and other rights of the holders of common stock. At present, we have no plans to issue any of the preferred stock.
Certain Anti-Takeover, Limited Liability and Indemnification Provisions
          Requirements for Advance Notification of Stockholder Nominations and Proposals. Our bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates

for election as directors, other than nominations made by or at the direction of the board of directors or one of its committees.
          No Action without Meeting. Our certificate of incorporation and bylaws provide that action required or permitted to be taken by our stockholders at any special or annual meeting of stockholders must be effected at a duly called annual or special meeting of stockholders and may not be taken or effected by a written consent of stockholders in lieu of a duly called meeting.
          Special Meetings. Our certificate of incorporation and bylaws provide that, except as otherwise required by statute or future rights, if any, of the holders of any series of preferred stock, special meetings of the stockholders may only be called by our board of directors acting pursuant to a resolution approved by the affirmative vote of a majority of the directors then in office. Only those matters set forth in the notice of the special meeting may be considered or acted upon at a special meeting of stockholders.
          No Cumulative Voting. The Delaware General Corporation Law provides that stockholders are denied the right to cumulate votes in the election of directors unless our certificate of incorporation provides otherwise. Our certificate of incorporation does not provide for cumulative voting of shares.
          Delaware Anti-Takeover Law. We are a Delaware corporation subject to Section 203 of the Delaware General Corporation Law. Under Section 203, certain “business combinations” between a Delaware corporation whose stock generally is publicly traded or held of record by more than 2,000 stockholders and an “interested stockholder” are prohibited for a three-year period following the date that such stockholder became an interested stockholder, unless:
  the corporation has elected in its certificate of incorporation not to be governed by Section 203;
 
  the business combination or the transaction which resulted in the stockholder becoming an interested stockholder was approved by the board of directors of the corporation before such stockholder became an interested stockholder;
 
  upon consummation of the transaction that made such stockholder an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the commencement of the transaction excluding voting stock owned by directors who are also officers or held in employee benefit plans in which the employees do not have a confidential right to tender stock held by the plan in a tender or exchange offer; or
 
  the business combination is approved by the board of directors of the corporation and authorized at a meeting by two-thirds of the voting stock which the interested stockholder did not own.
          The three-year prohibition also does not apply to some business combinations proposed by an interested stockholder following the announcement or notification of an extraordinary transaction involving the corporation and a person who had not been an interested stockholder during the previous three years or who became an interested stockholder with the approval of a majority of the corporation’s directors. The term “business combination” is defined generally to include mergers or consolidations between a Delaware corporation and an interested stockholder, transactions with an interested stockholder involving the assets or stock of the corporation or its majority-owned subsidiaries, and transactions which increase an interested stockholder’s percentage ownership of stock. The term “interested stockholder” is defined generally as those stockholders who become beneficial owners of 15% or more of a Delaware corporation’s voting stock, together with the affiliates or associates of that stockholder.
          Limitation of Officer and Director Liability and Indemnification Arrangements. Our certificate of incorporation limits the liability of our directors to the maximum extent permitted by Delaware law.

Table of Contents

Delaware law provides that directors will not be personally liable for monetary damages for breach of their fiduciary duties as directors, except liability for:
  any breach of their duty of loyalty to the corporation or its stockholders;
 
  acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;
 
  unlawful payments of dividends or unlawful stock repurchases or redemptions; or
 
  any transaction from which the director derived an improper personal benefit.
          This charter provision has no effect on any non-monetary remedies that may be available to us or our stockholders, nor does it relieve us or our officers or directors from compliance with federal or state securities laws. The certificate also generally provides that we shall indemnify, to the fullest extent permitted by law, any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit, investigation, administrative hearing or any other proceeding by reason of the fact that he is or was a director or officer of ours, or is or was serving at our request as a director, officer, employee or agent of another entity, against expenses incurred by him in connection with such proceeding. An officer or director shall not be entitled to indemnification by us if:
  the officer or director did not act in good faith and in a manner reasonably believed to be in, or not opposed to, our best interests; or
 
  with respect to any criminal action or proceeding, the officer or director had reasonable cause to believe his conduct was unlawful.
          These charter and bylaw provisions and provisions of Delaware law may have the effect of delaying, deterring or preventing a change of control of Altra Holdings, Inc.

Corporate Opportunity
          Our certificate of incorporation provides that our principal equity sponsor, Genstar Capital LLC, has no obligation to offer us an opportunity to participate in business opportunities presented to the sponsor or its affiliates, even if the opportunity is one that we might reasonably have pursued, and that neither the sponsor nor its affiliates will be liable to us or our stockholders for any breach of any duty by reason of any such activities unless, in the case of any person who is a director or officer of our company, such business opportunity is expressly offered to such director or officer in writing solely in his or her capacity as a director or officer of our company.

DESCRIPTION OF INDEBTEDNESS
Senior Revolving Credit Facility
          We summarize below the principal terms of the agreements that govern our senior revolving credit facility. This summary is not a complete description of all of the terms of the agreements.
          General. On November 30, 2004, the Borrowers entered into a senior revolving credit facility with the lenders signatory thereto and Wells Fargo Foothill, Inc., as the arranger and administrative agent. The senior revolving credit facility is in an aggregate amount of up to $30.0 million. Up to $10.0 million of the senior revolving credit facility is available in the form of letters of credit and amounts repaid under the senior revolving credit facility may be reborrowed (subject to satisfaction of the applicable borrowing conditions, including availability under a borrowing base formula) at any time prior to the maturity of the senior revolving credit facility, which will be November 30, 2009. Our availability under the senior revolving credit facility is based on a formula that calculates the borrowing base, based on a percentage of the value of accounts receivable, inventory, owned real property and equipment, subject to customary eligibility requirements and net of customary reserves. All borrowings are subject to the satisfaction of customary conditions, including delivery of borrowing notice, accuracy of representations and warranties in all material respects and absence of defaults. Proceeds of the senior revolving credit facility will be used to provide working capital and for general corporate purposes, including permitted acquisitions, if any, and general corporate needs.
          Interest and Fees. Borrowings under the senior revolving credit facility bear interest, at our option, at the prime rate plus 1.25%, in the case of prime rate loans, or the LIBOR rate plus 2.50%, in case of LIBOR rate loans. At no time will the indebtedness under the senior revolving credit facility bear interest at a rate per annum less than 3.75%.
          We will pay 2.0% per annum on all outstanding letters of credit, unused revolver fees in an amount equal to 0.375% per year on the unused commitments under the senior revolving credit facility, and servicing fees of $10,000 per quarter. These fees are payable quarterly in arrears and upon the maturity or termination of the commitments, calculated based on the number of days elapsed in a 360-day year. We paid a one-time closing fee of $375,000 to Wells Fargo Foothill, Inc. and approximately $1.2 million of related accounting, legal and other professional fees.
          Guarantees and Collateral. Certain of our existing and subsequently acquired or organized domestic subsidiaries which are not Borrowers do and will guarantee (on a senior secured basis) the senior revolving credit facility. Obligations of the other Borrowers under the senior revolving credit facility and the guarantees are secured by substantially all of the Borrowers’ assets and the assets of each of our existing and subsequently acquired or organized domestic subsidiaries that is a guarantor of our obligations under the senior revolving credit facility (with such subsidiaries being referred to as the “U.S. subsidiary guarantors”), including but not limited to: (a) a first-priority pledge of all the capital stock of subsidiaries held by all of the Borrowers or any U.S. subsidiary guarantor (which pledge, in the case of any foreign subsidiary, will be limited to 100% of any non-voting stock and 65% of the voting stock of such foreign subsidiary) and (b) perfected first-priority security interests in and mortgages on substantially all of the tangible and intangible assets of each Borrower and U.S. subsidiary guarantor, including accounts receivable, inventory, equipment, general intangibles, investment property, intellectual property, real property (other than (i) leased real property and (ii) the Borrowers’ existing and future real property located in the State of New York), cash and proceeds of the foregoing (in each case subject to materiality thresholds and other exceptions).
          Covenants and Other Matters. The senior revolving credit facility requires us to comply with a minimum fixed charge coverage ratio (when availability falls below $12,500,000) of 1.10 for the four quarter period ended December 31, 2005 and 1.20 for all four quarter periods thereafter. There is a maximum annual limit on capital expenditures of $11.0 million for fiscal year 2006, $9.8 million for fiscal year 2007, $10.0 million for fiscal year 2008, and $10.3 million for fiscal year 2009 and each fiscal year thereafter, provided that unspent amounts from prior periods may be used in future fiscal years.

          We would suffer an event of default under the senior revolving credit facility for a change of control if: (i) prior to an initial public offering, 50% of Altra Industrial’s voting stock is no longer beneficially owned by Genstar Capital, L.P. and its affiliates, (ii) after an initial public offering, if a person or group, other than Genstar Capital, L.P. and its affiliates, beneficially owns more than 35% of Altra Industrial’s stock and such amount is more than the amount of shares owned by Genstar Capital, L.P. and its affiliates, (iii) Altra Industrial ceases to own or control 100% of each of its borrower subsidiaries, or (iv) a change of control occurs under the notes or any other subordinated indebtedness.
          We would cause an event of default under the senior revolving credit facility if an event of default occurs under the indenture or if there is a default under any other indebtedness any Borrower may have involving an aggregate amount of $3 million or more and such default: (i) occurs at final maturity of such debt, (ii) allows the lender thereunder to accelerate such debt or (iii) causes such debt to be required to be repaid prior to its stated maturity. An event of default would also occur under the senior revolving credit facility if any of the indebtedness under the senior revolving credit facility ceases to be senior in priority to any of our other contractually subordinated indebtedness, including the obligations under the 9% senior secured notes and the 11 1 / 4 % senior notes.
          The senior revolving credit facility contains customary representations and warranties and affirmative covenants.
9% Senior Secured Notes due 2011
          As of September 29, 2006, our wholly owned subsidiary, Altra Industrial, had outstanding 9% senior secured notes in an aggregate principal amount of $165.0 million. The 9% senior secured notes are general obligations and are secured on a second-priority basis, equally and ratably, by security interests in substantially all our assets (other than certain excluded assets) and all of our capital stock, subject only to first-priority liens securing our senior credit facility and other permitted prior liens. Except with respect to payments from the liquidation of collateral securing the first-priority liens as held by our senior revolving credit facility, the 9% senior secured notes are pari passu in right of payment with all of our senior indebtedness, but to the extent of the security interests, effectively senior to all of our unsecured indebtedness, including the 11 1 / 4 % senior notes, and unsecured trade credit. The 9% senior secured notes are senior in right of payment to any future subordinated indebtedness and are unconditionally guaranteed by all of Altra Industrial’s existing and future domestic restricted subsidiaries.
          The indenture governing our 9% senior secured notes contains covenants which restrict our restricted subsidiaries. These restrictions limit or prohibit, among other things, their ability to:
  incur additional indebtedness;
 
  repay subordinated indebtedness prior to stated maturities;
 
  pay dividends on or redeem or repurchase stock or make other distributions;
 
  issue capital stock;
 
  make investments or acquisitions;
 
  sell certain assets or merge with or into other companies;
 
  restrict dividends, distributions or other payments from our subsidiaries;
 
  sell stock in our subsidiaries;
 
  create liens;
 
  enter into certain transactions with stockholders and affiliates; and
 
  otherwise conduct necessary corporate activities.
          In addition, if we experience a change of control, Altra Industrial will be required to offer to purchase all of the outstanding 9% senior secured notes at a purchase price in cash equal to 101% of the

83


Table of Contents

principal amount thereof on the date of purchase, plus accrued and unpaid interest, if any, to the date of purchase. Under the indenture governing the 9% senior secured notes, a change of control will have occurred if, after an initial public offering, a person or group, other than Genstar Capital, L.P. and its affiliates, beneficially owns more than 35% of Altra Industrial’s stock and such amount is more than the amount of shares owned by Genstar Capital, L.P. and its affiliates.
11 1 / 4 % Senior Notes due 2013
          As of September 29, 2006, Altra Industrial had outstanding 11 1 / 4 % senior notes in an aggregate principal amount of £33 million. The 11 1 / 4 % senior notes are our general obligations. The 11 1 / 4 % senior notes are junior to all of our secured indebtedness, including the 9% senior secured notes. The senior are unconditionally guaranteed by all of our existing and future domestic restricted subsidiaries.
          The indenture governing our 11 1 / 4 % senior notes contains covenants which restrict our restricted subsidiaries. These restrictions limit or prohibit, among other things, their ability to:
  incur additional indebtedness;
 
  repay subordinated indebtedness prior to stated maturities;
 
  pay dividends on or redeem or repurchase stock or make other distributions;
 
  sell certain assets or merge with or into other companies;
 
  restrict dividends, distributions or other payments from our subsidiaries;
 
  create liens;
 
  enter into certain transactions with stockholders and affiliates; and
 
  otherwise conduct necessary corporate activities.
          If we experience a change of control, Altra Industrial will be required to offer to purchase all of the outstanding 11 1 / 4 % senior notes at a purchase price in cash equal to 101% of the principal amount thereof on the date of purchase, plus accrued and unpaid interest, if any, to the date of purchase. Under the indenture governing the 11 1 / 4 % senior notes, a change of control will have occurred if, after an initial public offering, a person or group, other than Genstar Capital, L.P. and its affiliates, beneficially owns more than 35% of our stock and such amount is more than the amount of shares owned by Genstar Capital, L.P. and its affiliates.
CDPQ Subordinated Note
          In connection with the PTH Acquisition, we issued $14.0 million of subordinated notes to CDPQ. During the nine month period ended September 29, 2006, Altra Industrial prepaid approximately $12.5 million of our debt owed to CDPQ and also paid approximately $0.8 million and $0.8 million of interest and prepayment premium, respectively.
Mortgage
          In June 2006, our German subsidiary, Stieber GmbH, entered into a mortgage on its building in Heidelberg, Germany with a local bank. The mortgage has a principal of 2.0 million and an interest rate of 5.75% and is payable in monthly installments over 15 years.
Capital Leases
          We have entered into capital leases for certain buildings and equipment. As of September 29, 2006 we had approximately $2.1 million of outstanding capital lease obligations.

SHARES ELIGIBLE FOR FUTURE SALE
          Prior to the offering, there has been no public market for our common stock. If our stockholders sell substantial amounts of our common stock, in the public market following the offering, the market price of our common stock could decline. These sales also might make it more difficult for us to sell equity or equity-related securities in the future at a time and price that we deem appropriate.
          Upon completion of the offering, we will have outstanding an aggregate of 23,087,591 shares of our common stock, assuming no exercise of the underwriters’ over-allotment option. Of these shares, all of the shares sold in the offering will be freely tradeable without restriction or further registration under the Securities Act, unless the shares are purchased by “affiliates” as that term is defined in Rule 144 under the Securities Act. This leaves 13,087,591 shares eligible for sale in the public market, all of which are subject to the lock-up arrangement described below.
Rule 144
          In general, under Rule 144 of the Securities Act as currently in effect, beginning 90 days after the date of this prospectus, a person who has beneficially owned shares of our common stock for at least one year would be entitled to sell within any three-month period a number of shares that does not exceed the greater of:
  1% of the number of shares of our common stock then outstanding, which will equal approximately 230,876 shares immediately after the offering; or
 
  the average weekly trading volume of our common stock on the NASDAQ during the four calendar weeks preceding the filing of a notice on Form 144 with respect to that sale.
          Sales under Rule 144 are also subject to manner of sale provisions and notice requirements and to the availability of current public information about us.
Rule 144(k)
          Under Rule 144(k), a person who is not deemed to have been one of our affiliates at any time during the three months preceding a sale, and who has beneficially owned the shares proposed to be sold for at least two years, including the holding period of any prior owner other than an affiliate, is entitled to sell those shares without complying with the manner of sale, public information, volume limitation or notice provisions of Rule 144.
Lock-Up Agreements
          All of our officers, and directors and stockholders have entered into lock-up agreements under which they agreed not to transfer or dispose of, directly or indirectly, any shares of our common stock or any securities convertible into or exercisable or exchangeable for shares of our common stock, except for shares sold in this offering by the selling stockholders, for a period of 180 days after the date of this prospectus without the prior written consent of Merrill Lynch, Pierce, Fenner & Smith Incorporated on behalf of the underwriters. The 180-day period is subject to extension as described under “Underwriting.”
Rule 701
          In general, under Rule 701 of the Securities Act as currently in effect, any of our employees, consultants or advisors who purchase shares of our common stock from us in connection with a compensatory stock or option plan or other written agreement is eligible to resell those shares 90 days after the effective date of the offering in reliance on Rule 144, but without compliance with some of the restrictions, including the holding period, contained in Rule 144.

Registration of Shares under Stock Plans
          Following this offering, we intend to file a registration statement on Form  S-8 under the Securities Act covering shares of common stock issued or issuable upon the exercise of stock options or the settlement of restricted stock awards under the equity incentive plan granted after the date hereof. As of the date of the prospectus, we have 1,000,000 shares reserved but unissued under the equity incentive plan. Shares issued upon the exercise of stock options or the settlement of other equity awards after the effective date of the applicable Form  S-8 registration statement under which such shares are registered will be eligible for resale in the public market without restriction, subject to Rule 144 limitations applicable to affiliates and the lock-up arrangements described above. See “Management — Equity Incentive Plan.”
MATERIAL UNITED STATES TAX CONSIDERATIONS FOR
NON-U.S.  HOLDERS OF COMMON STOCK
          The following is a summary of the material U.S. federal income and estate tax consequences to non-U.S.  holders of the purchase, ownership and disposition of our common stock, but is not a complete analysis of all the potential tax considerations relating thereto. The summary is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), Treasury regulations promulgated thereunder, administrative rulings and judicial decisions, all as of the date of this prospectus (the “Tax Authorities”). The Tax Authorities may be changed or interpreted differently, possibly retroactively, so as to result in U.S. federal income or estate tax consequences different from those set forth below. The summary is applicable only to non-U.S.  holders who hold our common stock as a capital asset (generally, an asset held for investment purposes). We have not sought any ruling from the Internal Revenue Service, (the “IRS”), with respect to the statements made and the conclusions reached in the summary, and there can be no assurance that the IRS will agree with such statements and conclusions.
          This summary also does not address the tax considerations arising under the laws of any state, local or non-U.S.  jurisdiction. In addition, this discussion does not address tax considerations applicable to an investor’s particular circumstances or to investors that may be subject to special tax rules, including, without limitation:
  banks, insurance companies, regulated investment companies or other financial institutions;
 
  persons subject to the alternative minimum tax;
 
  tax-exempt organizations;
 
  dealers in securities, commodities or currencies;
 
  traders in securities that elect to use a mark-to -market method of accounting for their securities holdings;
 
  partnerships or other pass-through entities or investors in such entities;
 
  “controlled foreign corporations,” “passive foreign corporations,” and corporations that accumulate earnings to avoid U.S. federal income tax;
 
  U.S. expatriates or former long-term residents of the United States;
 
  persons who hold our common stock as a position in a hedging transaction, “straddle,” “conversion transaction” or other risk reduction or integrated transaction; or
 
  persons deemed to sell our common stock under the constructive sale provisions of the Code.
          In addition, if a partnership or other pass-through entity (including an entity or arrangement treated as a partnership or other type of pass-through entity for U.S. federal income tax purposes) owns our common stock, the tax treatment of a partner or beneficial owner of the partnership or other pass-through entity generally will depend on the status of the partner or beneficial owner and the activities of

86


Table of Contents

the partnership or entity and certain determinations made at the partner or beneficial owner level. Accordingly, partners and beneficial owners in partnerships or other pass-through entities that own our common stock should consult their own tax advisors as to the particular U.S. federal income and estate tax consequences applicable to them.
          This discussion is for general information only and is not tax advice. You are urged to consult your tax advisor with respect to the application of the U.S. federal income and estate tax laws to your particular situation, as well as any tax consequences of the purchase, ownership and disposition of our common stock arising under the U.S. gift tax rules or under the laws of any state, local, foreign or other taxing jurisdiction or under any applicable tax treaty.
Non-U.S.  Holder Defined
  For purposes of this discussion, you are a non-U.S.  holder if you are a beneficial owner of our common stock that, for U.S. federal income tax purposes, is not a U.S. person. For purposes of this discussion, a U.S. person is:
 
  an individual who is a citizen or resident of the United States, including an alien individual who is a lawful permanent resident of the United States or who meets the “substantial presence” test under Section 7701(b) of the Code;
 
  a corporation or other entity taxable as a corporation for U.S. federal tax purposes created or organized in the United States or under the laws of the United States or of any state therein or the District of Columbia;
 
  an estate whose income is subject to U.S. federal income tax regardless of its source; or
 
  a trust (1) whose administration is subject to the primary supervision of a U.S. court and of which one or more U.S. persons has the authority to control all substantial decisions of the trust or (2) that has made a valid election to be treated as a U.S. person.
Distributions
          If distributions are made on shares of our common stock, those payments will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent those distributions exceed both our current and our accumulated earnings and profits, they will constitute a return of capital and will first reduce your adjusted tax basis in our common stock, but not below zero, and then will be treated as gain from the sale of stock.
          Any dividend paid to you that is not effectively connected with your conduct of a U.S. trade or business generally will be subject to withholding of U.S. federal income tax either at a rate of 30% of the gross amount of the dividend or such lower rate as may be specified by an applicable tax treaty. In order to receive a reduced treaty rate, you must provide an IRS Form W-8BEN or other appropriate version of IRS Form W-8 certifying qualification for the reduced rate in accordance with applicable certification and disclosure requirements. Non-U.S.  holders should consult their own tax advisors regarding their entitlement to benefits under a relevant tax treaty and the manner of claiming the benefits.
          Dividends received by you that are effectively connected with your conduct of a U.S. trade or business (and, if required by an applicable tax treaty, are attributable to a U.S. permanent establishment maintained by you) are exempt from such withholding tax. In order to obtain this exemption, you must provide an IRS Form W-8ECI properly certifying such exemption in accordance with applicable certification and disclosure requirements. Such effectively connected dividends, although not subject to withholding tax, are taxed at the same graduated rates applicable to U.S. persons, net of any allowable deductions and credits. In addition, if you are a corporate non-U.S.  holder, dividends you receive that are effectively connected with your conduct of a U.S. trade or business may also be subject to a branch profits tax at a rate of 30% or such lower rate as may be specified by an applicable tax treaty.

87


Table of Contents

          If you are eligible for a reduced rate of withholding tax pursuant to a tax treaty, you may obtain a refund of any excess amounts currently withheld if you file an appropriate claim for refund with the IRS in a timely manner.
Gain on Disposition of Common Stock
          You generally will not be required to pay U.S. federal income tax on any gain realized upon the sale or other disposition of our common stock unless:
  the gain is effectively connected with your conduct of a U.S. trade or business (and, if required by an applicable tax treaty, is attributable to a U.S. permanent establishment maintained by you);
 
  you are an individual who is present in the United States for a period (or periods) aggregating 183 days or more during the calendar year in which the sale or disposition occurs and certain other conditions are met; or
 
  our common stock constitutes a U.S. real property interest by reason of our status as a “United States real property holding corporation” for U.S. federal income tax purposes (a USRPHC) at any time within the shorter of the five-year period preceding the disposition or your holding period for our common stock.
          We believe that we are not currently and will not become a USRPHC. However, because the determination of whether we are a USRPHC depends on the fair market value of our U.S. real property relative to the fair market value of our other business assets, we cannot assure you that we will not become a USRPHC in the future. Even if we become USRPHC, however, as long as our common stock is regularly traded on an established securities market, such common stock will be treated as U.S. real property interests only if you actually or constructively hold more than 5% of our common stock.
          If you are a non-U.S.  holder described in the first bullet above (pertaining to effectively connected gain), you will be required to pay tax on the net gain derived from the sale under regular graduated U.S. federal income tax rates applicable to U.S. persons, and corporate non-U.S.  holders described in the first bullet above may be subject to the branch profits tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. If you are an individual non-U.S.  holder described in the second bullet above (pertaining to presence in the United States), even though you are not considered a resident alien under the Code, you will be required to pay a flat 30% tax on the gain derived from the sale, which gain for such purposes may be offset by U.S. source capital losses. You should consult any applicable income tax treaties, which may provide for different rules.
Federal Estate Tax
          Our common stock that is owned or treated as owned by an individual who is not a U.S. citizen or resident of the United States (as specifically defined for U.S. federal estate tax purposes) at the time of death will be included in the individual’s gross estate for U.S. federal estate tax purposes, unless an applicable estate tax or other treaty provides otherwise and, therefore, may be subject to U.S. federal estate tax.
Backup Withholding and Information Reporting
          Generally, we must report annually to the IRS the amount of dividends paid to you, your name and address and the amount of tax withheld, if any. A similar report is sent to you. These information reporting requirements apply even if withholding was not required. Pursuant to tax treaties or other agreements, the IRS may make its reports available to tax authorities in your country of residence.
          Payments of dividends made to you will not be subject to backup withholding if you establish an exemption, for example by properly certifying your non-U.S.  status on a Form W-8BEN or another appropriate version of Form W-8. Notwithstanding the foregoing, backup withholding currently at a rate of

88


Table of Contents

28%, may apply if either we or our paying agent has actual knowledge, or reason to know, that you are a U.S. person.
          Payments of the proceeds from a disposition of our common stock affected outside the United States by a non-U.S.  holder made by or through a foreign office of a broker generally will not be subject to information reporting or backup withholding. Information reporting (but not backup withholding) will apply to such a payment, however, if the broker is a U.S. person, a controlled foreign corporation for U.S. federal income tax purposes, a foreign person 50% or more of whose gross income is effectively connected with a U.S. trade or business for a specified three-year period or a foreign partnership with certain connections with the United States, unless the broker has documentary evidence in its records that the beneficial owner is a non-U.S.  holder and specified conditions are met or an exemption is otherwise established.
          Payments of the proceeds from a disposition of our common stock by a non-U.S.  holder made by or through the U.S. office of a broker is generally subject to information reporting and backup withholding unless the non-U.S.  holder certifies as to its non-U.S.  holder status under penalties of perjury or otherwise establishes an exemption from information reporting and backup withholding.
          Backup withholding is not an additional tax. Rather, the U.S. income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund or credit may be obtained, provided that the required information is furnished to the IRS in a timely manner.

          The underwriters have agreed to purchase all of the shares sold under the purchase agreement if any of these shares are purchased. If an underwriter defaults, the purchase agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the purchase agreement may be terminated. The closings for the sale of shares to be purchased by the underwriters are conditioned on one another.
          We and the selling stockholders have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make in respect of those liabilities.
          The underwriters are offering the shares, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the shares, and other conditions contained in the purchase agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.
Commissions and Discounts
          The underwriters have advised us and the selling stockholders that they propose initially to offer the shares to the public at the initial public offering price on the cover page of this prospectus and to dealers at that price less a concession not in excess of $           per share. The underwriters may allow, and the dealers may reallow, a discount not in excess of $           per share to other dealers. After the initial public offering, the public offering price, concession and discount may be changed.
          The following table shows the public offering price, underwriting discount and proceeds before expenses to Altra Holdings, Inc. and the selling stockholders.

Overallotment Option
          The selling stockholders have granted an option to the underwriters to purchase up to 1,500,000 additional shares at the public offering price less the underwriting discount. The underwriters may exercise this option for 30 days from the date of this prospectus solely to cover any over-allotments. If the underwriters exercise this option, each will be obligated, subject to conditions contained in the purchase agreement, to purchase a number of additional shares proportionate to that underwriter’s initial amount reflected in the above table.
Reserved Shares
          At our request, the underwriters have reserved for sale, at the initial public offering price, up to 5% of the shares offered by this prospectus for sale to some of our directors, officers, employees, distributors, dealers, business associates and related persons. If these persons purchase reserved shares, this will reduce the number of shares available for sale to the general public. Any reserved shares that are not orally confirmed for purchase within one day of the pricing of this offering will be offered by the underwriters to the general public on the same terms as the other shares offered by this prospectus.
No Sales of Similar Securities
          We and the selling stockholders and our executive officers and directors and all existing stockholders have agreed, with exceptions, not to sell or transfer any common stock for 180 days after the date of this prospectus without first obtaining the written consent of Merrill Lynch. Specifically, we and these other individuals have agreed, with certain exceptions, not to directly or indirectly:
  offer, pledge, sell or contract to sell any common stock,
 
  sell any option or contract to purchase any common stock;
 
  purchase any option or contract to sell any common stock;
 
  grant any option, right or warrant for the sale of any common stock;
 
  lend or otherwise dispose of or transfer any common stock;
 
  request or demand that we file a registration statement related to the common stock; or
 
  enter into any swap or other agreement that transfers; in whole or in part, the economic consequence of ownership of any common stock whether any such swap or transaction is to be settled by delivery of shares or other securities, in cash or otherwise.
          This lockup provision applies to common stock and to securities convertible into or exchangeable or exercisable for or repayable with common stock. It also applies to common stock owned now or acquired later by the person executing the agreement or for which the person executing the agreement later acquires the power of disposition.
          The 180-day restricted period will be automatically extended if (1) during the last 17 days of the 180-day restricted period the Company issues an earning release or material news or a material event relating to its business occurs or (2) prior to the expiration of the 180-day restricted period, the Company announces that it will release earnings results or becomes aware that material news or a material event will occur during the 16-day period beginning on the last day of the 180-day restricted period, in which case the restrictions described above will continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.
NASDAQ Listing
          We expect the shares to be approved for listing on the The NASDAQ Global Market under the symbol “AIMC.” In order to meet the requirements for listing on that exchange, the underwriters have undertaken to sell a minimum number of shares to a minimum number of beneficial owners as required by that exchange.

Table of Contents

          Before this offering, there has been no public market for our common stock. The initial public offering price will be determined through negotiations among us, the selling stockholders and the underwriters. In addition to prevailing market conditions, the factors to be considered in determining the initial public offering price are
  the valuation multiples of publicly traded companies that the underwriters believe to be comparable to us;
 
  our financial information;
 
  the history of, and the prospects for, our company and the industry in which we compete;
 
  an assessment of our management; its past and present operations, and the prospects for, and timing of, our future revenues;
 
  the present state of our development; and
 
  the above factors in relation to market values and various valuation measures of other companies engaged in activities similar to ours.
          An active trading market for the shares may not develop. It is also possible that after the offering the shares will not trade in the public market at or above the initial public offering price.
          The underwriters do not expect to sell more than 5% of the shares in the aggregate to accounts over which they exercise discretionary authority.
NASD Regulation
          Because more than ten percent of the net proceeds of the offering may be paid to members or affiliates of members of the National Association of Securities Dealers, Inc. (“NASD”) participating in the offering, the offering will be conducted in accordance with NASD Conduct Rule 2710(h). This rule requires that the public offering price of an equity security be no higher than the price recommended by a Qualified Independent Underwriter (“QIU”) which has participated in the preparation of the registration statement and performed its usual standard of due diligence with respect to that registration statement. Robert W. Baird & Co. Incorporated (“Robert W. Baird”) has agreed to act as QIU with respect to the offering. The price of the common stock will be no higher than that recommended by Robert W. Baird.
Price Stabilization, Short Positions and Penalty Bids
          Until the distribution of the shares is completed, SEC rules may limit underwriters and selling group members from bidding for and purchasing our common stock. However, the underwriters may engage in transactions that stabilize the price of the common stock, such as bids or purchases to peg, fix or maintain that price.
          In connection with the offering, the underwriters may purchase and sell our common stock in the open market. These transactions may include short sales, purchases on the open market to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriters of a greater number of shares than they are required to purchase in the offering. “Covered” short sales are sales made in an amount not greater than the underwriters’ option to purchase additional shares in the offering. The underwriters may close out any covered short position by either exercising their over-allotment option or purchasing shares in the open market. In determining the source of shares to close out the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the over-allotment option. “Naked” short sales are sales in excess of the over-allotment option. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our shares in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of shares made by the underwriters in the open market prior to the completion of the offering. The underwriters

may also impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased shares sold by or for the account of such underwriter in stabilizing or short covering transactions.
          Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market.
          Neither we nor any of the underwriters makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the common stock. In addition, neither we nor any of the underwriters makes any representation that the underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.
Other Relationships
          Jefferies & Company, Inc. served as the sole underwriter for the issuance of the 9% senior secured notes and the 11 1 / 4 % senior notes, for which they received total fees of $7,844,065. As of November 19, 2006, MLEMEA Principal Credit Group (MLEMEA), an affiliate of Merrill Lynch, Pierce, Fenner & Smith Incorporated, holds $35,048,250 of the 11 1 / 4 % senior notes. Also, from time to time Jefferies & Company, Inc. holds for its own account or the account of its customers long or short positions in our debt securities. Each of MLEMEA and Jefferies & Company, Inc. may receive a portion of the proceeds of this offering. Based on its holdings of the 11 1 / 4 % senior notes as of November 25, 2006, MLEMEA could receive total proceeds of $13.8 million from the redemption of 35 percent of the 11 1 / 4 % senior notes.

Report of Independent Registered Public Accounting Firm
To the Board of Directors
Altra Holdings, Inc.
          We have audited the accompanying consolidated balance sheets of Altra Holdings, Inc. (“the Company”), as of December 31, 2005 and 2004 and the related consolidated statements of operations and comprehensive loss, convertible preferred stock and stockholders’ equity, and cash flows for the year ended December 31, 2005 and the period from inception (December 1, 2004) through December 31, 2004, and the combined statements of operations and comprehensive income, stockholders’ equity and cash flows of the Predecessor for the period from January 1, 2004 through November 30, 2004, and for the year ended December 31, 2003. Our audits also included the financial statement schedules listed in the index at Item 16(b). These financial statements and schedules are the responsibility of management of the Company and its Predecessor. Our responsibility is to express an opinion on these financial statements based on our audits.
          We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Company’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
          In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Altra Holdings, Inc. at December 31, 2005 and 2004 and the consolidated results of the operations and cash flows of the Company for the year ended December 31, 2005 and the period from inception (December 1, 2004) through December 31, 2004, and the combined results of operations and cash flows of its Predecessor for the period from January 1, 2004 through November 30, 2004, and for the year ended December 31, 2003, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedules, when considered in relation to the basic financial statements taken as a whole, present fairly in all material respects the information set forth therein.

1. Description of Business and Summary of Significant Accounting Policies
Basis of Preparation and Description of Business
          Headquartered in Quincy, Massachusetts, Altra Holdings, Inc. (“the Company”) produces, designs and distributes a wide range of mechanical power transmission products, including industrial clutches and brakes, enclosed gear drives, open gearing and couplings. The Company consists of several power transmission component manufacturers including Warner Electric, Boston Gear, Formsprag Clutch, Stieber Clutch, Ameridrives Couplings, Wichita Clutch, Nuttall Gear, Kilian and Delroyd Worm Gear. The Company designs and manufactures products that serve a variety of applications in the food and beverage, material handling, printing, paper and packaging, specialty machinery, and turf and garden industries. Primary geographic markets are in North America, Western Europe and Asia.
          The Company was formed on November 30, 2004 following acquisitions of certain subsidiaries of Colfax Corporation (“Colfax”) and The Kilian Company (“Kilian”), both acquisitions of which are described in detail in Note 3. The consolidated financial statements of the Company include the accounts of the Company subsequent to November 30, 2004. The financial statements of “the Predecessor” include the combined historical financial statements of the Colfax entities acquired by the Company that formerly comprised the Power Transmission Group of Colfax, a privately-held industrial manufacturing company, that are presented for comparative purposes.
          Prior to May 30, 2003, the Predecessor was a group of entities under common control. On May 30, 2003, through a series of capital contributions and exchanges of equity securities by the Predecessor’s shareholders, entities that were under common ownership, became subsidiaries of Colfax. In addition, certain entities that were previously taxed at the shareholder level became taxable entities (see the discussion on income taxes below and Note 8).
          The historical financial results of Kilian, which was not related to the Predecessor, are not included in the presentation of Predecessor balances in the financial statements or the accompanying footnotes.
Principles of Consolidation
          The consolidated financial statements include the accounts of the Company, the Predecessor (where noted) and their wholly owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation.
Pro Forma (unaudited)
          The unaudited pro forma financial information presents the effects of the contemplated conversion of the preferred series A shares to common stock at a ratio of two-to-one and a two-for-one reverse stock split of the common stock outstanding as of the beginning of the period presented.
Net Income Per Share
          Basic earnings per share is based on the weighted average number of common shares outstanding, and diluted earnings per share is based on the weighted average number of common shares outstanding and all dilutive potential common equivalent shares outstanding. Common equivalent shares are included in the dilutive per share calculations when the effect of their inclusion would be dilutive.

          The following is a reconciliation of basic to diluted net income per share:
         
    Year Ended
    December 31,
    2005
     
Net Income
  $ 2,504  
       
Shares used in net income per common share — basic

Effect of dilutive securities:
       
Incremental shares of unvested restricted common stock

Shares used in net income per common share — diluted
    37,937  
       
Net income per common share — basic
  $ 139.11  
       
Net income per common share — diluted
  $ 0.07  
       
          There was no common stock outstanding for the one month period from December 1, 2004 to December 31, 2004 to establish a basic earnings per share. The Company did not generate earnings for the period from December 1, 2004 to December 31, 2004, therefore, the potential common stock equivalents were anti-dilutive and excluded from dilutive earnings per share.
          The Predecessor’s capital structure was comprised of contributions from the parent and affiliated companies. There was no common stock associated with the group of entities which comprised the Predecessor. Accordingly there is no respective earnings per share.
          Subsequent to year end, the Company granted 693,511 shares of restricted stock to certain employees. The restricted shares granted have similar terms to those issued under previous grants. This restricted stock is unvested and therefore would have no impact on calculating basic earnings per share had the grant occurred prior to December 31, 2005. This restricted stock would be dilutive had it been granted prior to December 31, 2005, however it would not have had a material impact on diluted earnings per share.
Fair Value of Financial Instruments
          The carrying values of financial instruments, including accounts receivable, accounts payable and other accrued liabilities, approximate their fair values due to their short-term maturities. The Company believes that the subordinated notes are carried at their fair value at December 31, 2005 based on estimated rates for similar borrowing by the Company. At December 31, 2005 the carrying amount of long-term debt of the 9% Senior Secured Notes was $159.4 million. The estimated fair value at December 31, 2005 was $160.1 million based on quoted market prices for such notes.
Use of Estimates
          The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the financial statements. Actual results could differ from those estimates.
Foreign currency translation
          Assets and liabilities of subsidiaries operating outside of the United States with a functional currency other than the U.S. dollar are translated into U.S. dollars using exchange rates at the end of the respective period. Revenues and expenses are translated at average exchange rates effective during the respective period.
          Foreign currency translation adjustments are included in accumulated other comprehensive income (loss) as a separate component of stockholders’ equity. Net foreign currency transaction gains and losses

are included in the results of operations in the period incurred and were not material in any of the periods presented.
Cash and Cash Equivalents
          Cash and cash equivalents include all financial instruments purchased with an initial maturity of three months or less. Cash equivalents are stated at cost, which approximates fair value.
Trade Receivables
          An allowance for doubtful accounts is recorded for estimated collection losses that will be incurred in the collection of receivables. Estimated losses are based on historical collection experience, as well as, a review by management of the status of all receivables. Collection losses have been within the Company’s expectations.
Inventories
          Inventories are stated at the lower of cost or market using the first-in, first-out (“FIFO”) method. The cost of inventories acquired by the Company in its acquisitions reflect their fair values at November 30, 2004 as determined by the Company based on the replacement cost of raw materials, the sales price of the finished goods less an appropriate amount representing the expected profitability from selling efforts, and for work-in -process the sales price of the finished goods less an appropriate amount representing the expected profitability from selling efforts and costs to complete.
          The Company periodically reviews its quantities of inventories on hand and compares these amounts to the expected usage of each particular product or product line. The Company records as a charge to cost of sales any amounts required to reduce the carrying value of inventories to net realizable value.
Property, Plant and Equipment
          Property, plant, and equipment are stated at cost, net of accumulated depreciation incurred since November 30, 2004.
          Depreciation of property, plant, and equipment is provided using the straight-line method over the estimated useful life of the asset, as follows:
     
Buildings and improvements
  15 to 45 years
Machinery and equipment
  2 to 15 years
          Improvements and replacements are capitalized to the extent that they increase the useful economic life or increase the expected economic benefit of the underlying asset. Repairs and maintenance expenditures are charged to expense as incurred.
Intangible Assets
          Intangibles represent product technology and patents, tradenames and trademarks and customer relationships. Product technology and patents and customer relationships are amortized on a straight-line basis over 8 to 12 years. The tradenames and trademarks are considered indefinite-lived assets and are not being amortized. Intangibles are stated at fair value on the date of acquisition net of accumulated amortization.
Goodwill
          Goodwill represents the excess of the purchase price paid by the Company for the Predecessor and Kilian over the fair value of the net assets acquired in each of the acquisitions. Goodwill can be

attributed to the value placed on the Company being an industry leader with a market leading position in the Power Transmission industry. The Company’s leadership position in the market was achieved by developing and manufacturing innovative products and management anticipates that its leadership position and profitability will continue to expand, enhanced by cost improvement programs associated with ongoing consolidation and centralization of it operations.
Impairment of Goodwill and Indefinite-Lived Intangible Assets
          The Company evaluates the recoverability of goodwill and indefinite-lived intangible assets annually, or more frequently if events or changes in circumstances, such as a decline in sales, earnings, or cash flows, or material adverse changes in the business climate, indicate that the carrying value of an asset might be impaired. Goodwill is considered to be impaired when the net book value of a reporting unit exceeds its estimated fair value. Fair values are established using a discounted cash flow methodology (specifically, the income approach). The determination of discounted cash flows is based on the Company’s strategic plans and long-range forecasts. The revenue growth rates included in the forecasts are the Company’s best estimates based on current and anticipated market conditions, and the profit margin assumptions are projected based on current and anticipated cost structures.
          Because the Company was still in the process of allocating its final goodwill and intangible assets, arising from the application of purchase accounting for the Predecessor and Kilian acquisitions, and had not allocated these assets across its business units, the Company evaluated its long-lived assets at the Company level at December 31, 2004. This analysis included consideration of discounted cash flows as well as EBITDA multiples. The analysis indicated no impairment to be present. During 2005, the Company completed its allocation of goodwill and intangible assets across its business units and performed its annual assessment at the reporting unit level noting no impairment of such assets.
Impairment of Long-Lived Assets Other Than Goodwill and Indefinite-Lived Intangible Assets
          The Company assesses its long-lived assets other than goodwill and indefinite-lived intangible assets for impairment whenever facts and circumstances indicate that the carrying amounts may not be fully recoverable. To analyze recoverability, the Company projects undiscounted net future cash flows over the remaining lives of such assets. If these projected cash flows are less than the carrying amounts, an impairment loss would be recognized, resulting in a write-down of the assets with a corresponding charge to earnings. The impairment loss is measured based upon the difference between the carrying amounts and the fair values of the assets. Assets to be disposed of are reported at the lower of the carrying amounts or fair value less cost to sell. Management determines fair value using the discounted cash flow method or other accepted valuation techniques.
Debt Issuance Costs
          Costs directly related to the issuance of debt are capitalized, included in other long-term assets and amortized using the effective interest method over the term of the related debt obligation. The net carrying value of debt issuance costs was approximately $3.9 million and $3.7 million at December 31, 2005 and 2004, respectively.
Revenue Recognition
          Product revenues are recognized, net of sales tax collected, at the time title and risk of loss pass to the customer, which generally occurs upon shipment to the customer. Service revenues are recognized as services are performed. Amounts billed for shipping and handling are recorded as revenue. Product return reserves are accrued at the time of sale based on the historical relationship between shipments and returns, and are recorded as a reduction of net sales.

Notes to Consolidated Financial Statements — (Continued)
          Certain large distribution customers receive quantity discounts which are recognized net at the time the sale is recorded.
Shipping and Handling Costs
          Shipping and handling costs associated with sales are classified as a component of cost of sales.
Warranty Costs
          Estimated expenses related to product warranties are accrued at the time products are sold to customers. Estimates are established using historical information as to the nature, frequency, and average costs of warranty claims.
Self-Insurance
          Certain operations are self-insured up to pre-determined amounts above which third-party insurance applies, for medical claims, workers’ compensation, vehicle insurance, product liability costs and general liability exposure. The accompanying balance sheets include reserves for the estimated costs associated with these self-insured risks, based on historic experience factors and management’s estimates for known and anticipated claims. A portion of medical insurance costs are offset by charging employees a premium equivalent to group insurance rates.
Research and Development
          Research and development costs are expensed as incurred.
Advertising
          Advertising costs are charged to selling, general, and administrative expenses as incurred and amounted to approximately $2.2 million, $0.2 million and $2.0 million, for the year ended December 31, 2005, and for the periods from December 1, 2004 through December 31, 2004 and January 1, 2004 through November 30, 2004 and less than $3.0 million in the year ended December 31, 2003.
Stock-Based Compensation
          In December 2004, the FASB issued Statement of Financial Accounting Standard (SFAS) No. 123(R), “Share-Based Payment,” which requires the measurement of all share-based payments to employees, including grants of employee stock options, using a fair-value-based method and the recording of such expense in the Company’s consolidated statement of operations.
          The Company established the 2004 Equity Incentive Plan that provides for various forms of stock based compensation to officers and senior-level employees of the Company. The Company accounts for grants under this plan in accordance with the provisions of SFAS No. 123(R). Expense associated with equity awards is recognized on a straight-line basis over the service period.
Income Taxes
          The Company records income taxes using the asset and liability method. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective income tax bases, and operating loss and tax credit carryforwards. The Company evaluates the realizability of its net deferred tax assets and assesses the need for a valuation allowance on a quarterly basis. The future benefit to be derived from its deferred tax assets is dependent upon the Company’s ability to generate sufficient future taxable income to realize the assets. The Company records a valuation allowance to reduce its net deferred

Notes to Consolidated Financial Statements — (Continued)
tax assets to the amount that may be more likely than not to be realized. To the extent the Company establishes a valuation allowance, an expense will be recorded within the provision for income taxes line on the statement of operations. In periods subsequent to establishing a valuation allowance, if the Company were to determine that it would be able to realize its net deferred tax assets in excess of their net recorded amount, an adjustment to the valuation allowance would be recorded as a reduction to income tax expense in the period such determination was made.
          Prior to various dates in mid-2003, only Boston Gear and the Predecessor’s non-U.S.  based subsidiaries were accounted for under this method. The remaining U.S. based Predecessor affiliates were S-corporations and/or partnerships for U.S. income tax purposes. As such, income tax obligations were the responsibility of the Predecessor’s shareholders and partners for those periods. During 2003, these remaining Predecessor affiliates became subject to tax at the entity level and income taxes have been provided for since those dates. The effects of recognizing deferred tax assets and liabilities related to this change in status have been included in the provision (benefit) for income taxes for the year ended December 31, 2003. For all Predecessor periods, no taxes payable or receivable have been recorded in the Predecessor financial statements subsequent to the entities becoming taxable. The related estimated income tax payable or receivable is included as a component of the net contribution from (distribution to) affiliates as shown in the accompanying Statement of Stockholders’ Equity. The U.S. based current tax expense or benefit is presented as deferred tax expense or benefit for all Predecessor periods presented, as no current tax benefits or losses accrue to the Company or its Predecessor due to utilization of consolidated net operating losses of the former owner.
2. Recent Accounting Pronouncements
          In May 2005, the FASB issued Statement of Financial Accounting Standards No. 154, (“Accounting Changes and Error Corrections, a replacement of APB Opinion No. 20, Accounting Changes and FASB Statement No. 3, Reporting Accounting Changes in Interim Financial Statements”)(“SFAS 154”). SFAS 154 provides guidance on the accounting for and reporting of accounting changes and error corrections. It establishes, unless impracticable, retrospective application as the required method for reporting a change in accounting principle in the absence of explicit transition requirements specific to the newly adopted accounting principle. SFAS 154 also provides guidance for determining whether retrospective application of a change in accounting principle is impracticable and for reporting a change when retrospective application is impracticable. The provisions of this Statement are effective for accounting changes and corrections of errors made in fiscal periods beginning after December 15, 2005. The adoption of the provisions of SFAS 154 is not expected to have a material impact on the Company’s financial position or results of operations.
          In November 2004, the FASB issued SFAS No. 151, “Inventory Costs, an amendment of ARB No. 43, Chapter 4” . SFAS No. 151, which is effective for the Company beginning January 1, 2006, SFAS No. 151 clarifies the accounting for abnormal amounts of idle facility expense, freight, handling costs, and wasted material (spoilage) so that those items are recognized as current-period charges. This statement also requires the allocation of fixed production overhead costs based on the normal capacity of the production facilities regardless of the actual use of the facility. The Company does not believe that this statement will have any material impact on the Company’s financial position or results of operations.
          In June 2006, the FASB issued FASB Interpretation No. (“FIN”) 48, “Accounting for Uncertainty in Income Taxes — An Interpretation of FASB Statement No. 109”, which prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN 48 will be effective for fiscal years beginning after December 15, 2006. The Company has not yet completed its evaluation of the impact of adoption on the Company’s financial position or results of operations.

3. Acquisitions
          On November 30, 2004, the Company acquired the Predecessor for $180.0 million in cash and Kilian for an $8.8 million issuance of preferred and common stock plus the assumption of Kilian debt in the amount of approximately $12.2 million. The purchase price of both acquisitions has been adjusted following the completion of certain negotiations surrounding adjustments to the respective seller’s recorded working capital at the acquisition date. In 2005 Predecessor negotiations were finalized resulting in the return of approximately $1.6 million of the purchase price to the Company. Negotiations were also finalized for Kilian which resulted in a final payment by the Company of approximately $0.7 million.
          The acquisitions have been accounted for in accordance with SFAS No. 141, “Business Combinations.” As discussed in the Basis of Presentation in Note 1, the consolidated financial statements include the results of operations for the period December 1, 2004 through December 31, 2004, and those of the Predecessor for prior periods.
          The Company has completed its purchase price allocations. The value of the acquired assets, assumed liabilities and identified intangibles from the acquisition of the Predecessor and Kilian, as presented below, are based upon management’s estimates of fair value as of the date of the acquisition. The goodwill and intangibles recorded in connection with the acquisition of the Predecessor have been allocated across the business units acquired from the Predecessor. The purchase price allocations are as follows (in thousands):

          The excess of the purchase price over the fair value of the net assets acquired was recorded as goodwill. The amounts recorded as identifiable intangible assets consist of the following:
                           
    Predecessor   Kilian   Total
             
Customer relationships
  $ 27,802     $     $ 27,802  
Product technology and patents
    5,122             5,122

Trade names and trademarks, not subject to amortization
    16,080             16,080  
                   
Total intangible assets
  $ 49,004     $     $ 49,004  
                   
          Customer relationships, product technology and patents, are subject to amortization over their estimated useful lives of twelve and eight years, respectively, which reflects the anticipated periods over which the Company estimates it will benefit from the acquired assets. The weighted average estimated useful life of all intangible assets subject to amortization is approximately 11.1 years. Substantially all of this amortization is deductible for income tax purposes.
          The following table sets forth the unaudited pro forma results of operations of the Company for the two years in the period ended December 31, 2004 as if the Company had acquired the Predecessor and Kilian as of January 1, 2003. The pro forma information contains the actual combined operating results of the Company, the Predecessor and Kilian with the results prior to the December 1, 2004 adjusted to include the pro forma impact of (i) additional amortization and depreciation expense associated with the adjustment to and recognition of fair value of fixed and intangible assets; (ii) the elimination of additional expense as a result of the fair value adjustment to inventory recorded in connection with the Acquisition; (iii) additional expenses associated with new contractual commitments created at Inception; (iv) additional expenses associated with general and administrative services previously performed by the Predecessor’s parent and not charged to the Predecessor; (v) additional interest expense associated with debt issued at Inception; (vi) the elimination of previously incurred interest expense of the Predecessor and Kilian; and (vii) the elimination of expense associated with pension and OPEB obligations retained by the Predecessor. These pro forma amounts do not purport to be indicative of the results that would have actually been obtained if the acquisitions occurred as of January 1, 2003 or that may be obtained in the future.

6. Goodwill and Intangible Assets
          Goodwill and other intangibles as of December 31, 2005 and 2004 consisted of the following:
           
Goodwill
       
 
Balance December 31, 2004
  $ 63,145

Impact of changes in foreign currency
    (1,055 )
       
 
Balance December 31, 2005
  $ 65,345  
       
          The Goodwill adjustments primarily relate to the finalization of the recorded working capital balances for both the Kilian and Predecessor acquisitions, which resulted in a decrease in goodwill of $0.9 million. Goodwill was further adjusted down by $2.0 million for deferred taxes that had been previously established as part of the purchase accounting. These decreases in goodwill were offset by an increase in the amount of assumed liabilities identified, of approximately, $6.1 million.

          Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the deferred tax assets and liabilities as of December 31, 2005 and 2004 were as follows:
                   
    2005   2004

          At December 31, 2005 and 2004, the Company had net operating loss carryforwards primarily related to operations in France of $5.0 million and $5.4 million, respectively, which can be carried forward indefinitely.
          The decrease in net deferred tax liabilities for the year includes a deferred tax benefit of approximately $2.0 million attributable to the release of valuation allowances established in purchase

accounting, resulting in a reduction of book goodwill, and a deferred tax benefit of approximately $1.9 million attributable to accrued pension liabilities and currency translation adjustments recorded through other comprehensive income.
          Valuation allowances are established for a deferred tax asset that management believes may not be realized. The Company continually reviews the adequacy of the valuation allowance and recognizes tax benefits only as reassessments indicate that it is more likely than not the benefits will be realized. A valuation allowance at December 31, 2005 and 2004 of $16.4 million and $18.4 million, respectively, has been recognized to offset deferred tax assets due to the uncertainty of realizing the benefits of the deferred tax assets. The decrease in the valuation allowance relates primarily to deferred tax adjustments associated with purchase price accounting and have been recorded to goodwill. Of the total valuation allowance existing at December 31, 2005, approximately $16.1 million will be allocated to reduce book goodwill if and when released in subsequent periods.
          The undistributed earnings of the Company’s foreign subsidiaries on which tax is not provided was approximately $0.4 million as of December 31, 2005, and are considered to be indefinitely reinvested. As of December 31, 2005, the Company has not recorded U.S. federal deferred income taxes on these undistributed earnings from its foreign subsidiaries. It is expected that these earnings will be permanently reinvested in operations outside the U.S. If the undistributed earnings were not reinvested in operations outside the U.S., the tax impact would be immaterial to the Company.
          The American Jobs Creation Act of 2004 (the “Job Creation Act”) was enacted on October 22, 2004. Among other things, the Job Creation Act repeals an export incentive and creates a new deduction for qualified domestic manufacturing activities. The Company has recorded in the computation of the account, a deduction of $0.1 million. In addition, the Job Creation Act also included a deduction of 85% of certain foreign earnings that are repatriated, as defined in the Job Creation Act. The Company did not repatriate any earnings in 2005 under this provision of the Job Creation Act.
9. Pension and Other Employee Benefits
Defined Benefit (Pension) and Postretirement Benefit Plans
          The Company’s, wholly-owned subsidiary Altra Industrial Motion, Inc. (Altra Industrial), sponsors various defined benefit (pension) and postretirement (medical and life insurance coverage) plans for certain, primarily unionized, active employees (those in the employment of Altra Industrial at or hired since November 30, 2004). The Predecessor sponsored similar plans that covered certain employees, former employees and eligible dependents. At November 30, 2004, Altra Industrial assumed the pension and postretirement benefit obligations of all active U.S. employees and all non-U.S.  employees of the Predecessor. Additionally, Altra Industrial assumed all post-employment and post-retirement welfare benefit obligations with respect to active U.S. employees. Colfax retained all other pension and postretirement benefit obligations relating to the Predecessor’s former employees.
          The accounting for these plans is subject to the guidance provided in SFAS No. 87, “Employers’ Accounting for Pensions,” and SFAS No. 106, “Employers’ Accounting for Postretirement Benefits Other than Pensions.” Both of these statements require management to make assumptions relating to the long-term rate of return on plan assets, discount rates used to measure future obligations and expenses, salary scale inflation rates, health care cost trend rates, and other assumptions. The selection of assumptions is based upon historical trends and known economic and market conditions at the time of valuation. Because of the volatility of the assumptions, actual results may vary substantially from forecast plan assumptions. Both the pension plans and the postretirement plans are revalued annually, using a December 31 measurement date, based upon updated assumptions and information about the individuals covered by the plan.

          The reasonableness of the expected return on the funded pension plan assets was determined by three separate analyses: (i) review of forty years of historical data of portfolios with similar asset allocation characteristics, (ii) analysis of six years of historical performance for the Predecessor plan assuming the current portfolio mix and investment manager structure, and (iii) a projected portfolio performance, assuming the plan’s target asset allocation.
          For measurement of the postretirement benefit obligations and net periodic benefit costs, an annual rate of increase in the per capita cost of covered health care benefits of approximately 7.5% was assumed. This rate was assumed to decrease gradually to 5% by 2008 and remain at that level thereafter.

          In December 2003, Congress passes the “Medicare Prescription Drug Improvement and Modernization Act of 2003” (the Act) that reformed Medicare in such a way that Altra Industrial may have been eligible to receive subsidies for certain prescription drug benefits that are incurred on behalf of plan participants. There has been no impact on Altra Industrial’s plans as either prescription drug coverage is not offered past the age of 65 or we have not applied for any subsidy. Accordingly, the amounts recorded and disclosed in these financial statements do not reflect any amounts related to this Act.

(i)  The assets for Altra Industrial’s funded retirement plan at the end of 2004 were held by the Predecessor, awaiting transfer. Once received, they were invested in a manner consistent with the 2005 target allocation.
          The investment strategy is to achieve a rate of return on the plan’s assets that, over the long-term, will fund the plan’s benefit payments and will provide for other required amounts in a manner that satisfies all fiduciary responsibilities. A determinant of the plan’s returns is the asset allocation policy. The plan’s asset mix will be reviewed by Altra Industrial periodically, but at least quarterly, to rebalance within the target guidelines. Altra Industrial will also periodically review investment managers to determine if the respective manager has performed satisfactorily when compared to the defined objectives, similarly invested portfolios, and specific market indices.
Expected cash flows
          The following table provides the amounts of expected benefit payments, which are made from the plans’ assets and includes the participants’ share of the costs, which is funded by participant contributions.

          Altra Industrial contributed $0.9 million to its pension plan in 2005. Altra Industrial has cash funding requirements associated with its pension plan which are estimated to be $6.9 million in 2006, $3.6 million in 2007, $2.5 million in 2008 and $1.9 million annually until 2011.
Defined Contribution Plans
          At November 30, 2004, Altra Industrial established a defined contribution plan for substantially all full-time U.S.-based employees on terms that mirror those previously provided by the Predecessor. All active employees became participants of Altra Industrial’s plan and all of their account balances in the Predecessor plans were transferred to Altra Industrial’s plan at Inception.
          Under the terms of both the Altra Industrial and Predecessor plans, eligible employees may contribute from one to fifteen percent of their compensation to the plan on a pre-tax basis. Altra Industrial makes a matching contribution equal to half of the first six percent of salary contributed by each employee and makes a unilateral contribution of three percent of all employees’ salary (including non-contributing employees). Altra Industrial’s expense associated with the defined contribution plan was $2.5 and $0.3 million during the year-ended December 31, 2005 and the period December 1, 2004 through December 31, 2004, respectively. The Predecessor’s expense was $2.4 million during the eleven months ending November 30, 2004, and $2.0 million in the year ending December 31, 2003.
10. Long-Term Debt
Revolving Credit Agreement
          At November 30, 2004, Altra Industrial entered into an agreement for up to $30 million of revolving borrowings from a commercial bank (the Revolving Credit Agreement), subject to certain limitations resulting from the requirement of Altra Industrial to maintain certain levels of collateralized assets, as defined in the Revolving Credit Agreement. Altra Industrial may use up to $10 million of its availability under the Revolving Credit Agreement for standby letters of credit issued on its behalf, the issuance of which will reduce the amount of borrowings that would otherwise be available to Altra Industrial. Altra Industrial may re-borrow any amounts paid to reduce the amount of outstanding borrowings; however, all borrowings under the Revolving Credit Agreement must be repaid in full as of November 30, 2009.
          Borrowings under the Revolving Credit Agreement bear interest, at Altra Industrial’s election, at LIBOR plus 250 basis points annually or the lenders Prime Rate plus 125 basis points, but in no event no lower than 3.75%. Altra Industrial must also pay 2.0% per annum on all outstanding letters of credit, 0.375% per annum on the unused availability under the Revolving Credit Agreement and $10 per quarter in service fees. Altra Industrial incurred approximately $1.5 million in fees associated with the issuance of the Revolving Credit Agreement which have been capitalized as deferred financing costs and will be amortized over the five year life of the Revolving Credit Agreement as a component of interest expense.
          Substantially all of Altra Industrial’s assets have been pledged as collateral against outstanding borrowings under the Revolving Credit Agreement. The Revolving Credit Agreement requires Altra Industrial to maintain a minimum fixed charge coverage ratio (when availability under the line falls below $12.5 million) and imposes customary affirmative covenants and restrictions on Altra Industrial. Altra Industrial was in compliance with certain covenants and obtained a waiver for noncompliance with one covenant at December 31, 2005. Altra Industrial was in compliance with all requirements of the Revolving Credit Agreement at December 31, 2004.
          There were no borrowings under the Revolving Credit Agreement at December 31, 2005 and 2004, however; the lender had issued $2.4 million and $1.9 million, respectively, of outstanding letters of credit on behalf of Altra Industrial.

9% Senior Secured Notes
          At November 30, 2004, Altra Industrial issued 9% Senior Secured Notes (Senior Notes), with a face value of $165 million. Interest on the Senior Notes is payable semiannually, in arrears, on June 1 and December 1 of each year, beginning June 1, 2005, at an annual rate of 9%. The effective interest rate on the Senior Notes is approximately 10.0%, after consideration of the amortization of $6.6 million related to initial offer discounts (included in long-term debt) and $2.7 million of deferred financing costs (included in other assets).
          The Senior Notes mature on December 1, 2011 unless previously redeemed by Altra Industrial. Through December 1, 2007, Altra Industrial may elect to redeem up to 35% of the Senior Notes with the proceeds of certain equity transactions by paying a 9% premium of the amounts paid by such redemption. From December 1, 2008 through November 30, 2009, Altra Industrial may also elect to redeem any or all of the Senior Notes still outstanding by paying a 4.5% premium of the amounts paid for such redemptions. A 2.25% premium is due for redemptions completed from December 1, 2009 to November 30, 2010. Subsequent to November 30, 2010, Altra Industrial may elect to redeem any or all of the Senior Notes then outstanding at face value.
          In connection with the issuance of the Senior Notes, Altra Industrial agreed to file a registration statement with the U.S. Securities and Exchange Commission in an effort to convert the Senior Notes to publicly traded instruments. Altra Industrial experienced delays in the effectiveness of such filing, and incurred additional interest at an annual rate of .25%, increasing by an additional .25% for each 90 day delay in the registration up to .75% of additional interest by the time the registration statement became effective. The additional interest expense included in the statement operations for the year ended December 31, 2005 was $0.4 million.
          The Senior Notes are guaranteed by Altra Industrial’s U.S. domestic subsidiaries and are secured by a second priority lien, subject to first priority liens securing the Revolving Credit Agreement, on substantially all of Altra Industrial’s assets. The Senior Notes contain numerous terms, covenants and conditions, which impose substantial limitations on Altra Industrial. With the exception of filing timely financial information, Altra Industrial was in compliance with all covenants of the Senior Notes at December 31, 2005. This by itself does not constitute an event of default nor trigger the callability of the Senior Notes. As of December 31, 2004 Altra Industrial was in compliance with all of the requirements of the Senior Notes.
Subordinated Notes
          At November 30, 2004, the Company executed an agreement with a stockholder to obtain $14.0 million of unsecured subordinated financing (the Subordinated Notes). The Subordinated Notes were issued at par value and mature on November 30, 2019. Interest accrues at an annual rate of 17% and is payable quarterly in full or paid-in -kind (PIK). As of December 31, 2004, the Company elected to accrue $198 thousand of interest expenses as PIK. During 2005, the Company paid all interest, including the 2004 PIK interest, in full. As of December 31, 2005, there was $595 thousand of accrued interest included in accruals and other liabilities in the accompanying balance sheet.
          The Subordinated notes become callable by the lender on December 1, 2011 or upon full payment of the 9% Senior Secured notes discussed above. The lender also has the right to demand payment at 101% upon change of control. The company may elect to redeem the Subordinated Notes at any time in whole or in part. Payments made prior to November 30, 2006 will incur a 6% prepayment penalty. This prepayment penalty decreases by 1% on every subsequent anniversary date.
          The Company incurred approximately $0.3 million in fees associated with the issuance of the Subordinated Notes that are capitalized as deferred financing costs included in other assets in the

F-23

accompanying balance sheet. These costs will be amortized through November 2011 as a component of interest expense.
          The Subordinated Notes impose customary affirmative covenants and restrictions on the Company, including the delivery of timely financial information to the lender. With the exception of filing timely financial information, the Company was in compliance with all covenants of the Subordinated Notes at December 31, 2005. The Company obtained a waiver of this covenant requirement from the holder of the Subordinated Notes. The Company was in compliance with all covenant requirements as of December 31, 2004.
Predecessor Debt
          During 2003, the Predecessor borrowed $70.6 million from its parent company which was used to retire all, then existing, bank debt. In connection with the repayment of the bank debt, the Predecessor wrote off $0.4 million of deferred financing costs, which was charged to the gain on sale of assets and other non-operating expense (income) caption in the statement of operations. The amounts borrowed from the parent company bore an interest rate of 5.83% which approximated the rates incurred by the parent company for their third-party debt.
Capital Leases (see also Note 16)
          The Company and the Predecessor lease a building and certain equipment under capital lease arrangements, whose obligations are included in both short-term and long-term debt. Capital lease obligations amounted to approximately $0.3 million and $1.1 million at December 31, 2005 and 2004, respectively. Assets under capital leases are included in property, plant and equipment with the related amortization recorded as depreciation expense.
11. Convertible Preferred Stock
          The Company has authorized 40,000,000 shares of Series A Convertible Preferred Stock (the Preferred), 35,500,000 and 35,100,000 of which was outstanding as of December 31, 2005 and 2004, respectively. The initial 35,100,000 Preferred shares were issued in connection with the acquisitions discussed in Note 3. An additional 400,000 Preferred shares were purchased by certain members of management in 2005. A Preferred holder is also the holder of the Company’s Subordinated Notes, discussed in Note 10. The Preferred Stock holders are entitled to the following rights:
Dividends
          The holders of the outstanding Preferred Stock are entitled to receive, when and if declared by the Board, non-cumulative cash dividends at an annual rate of $0.08 per share of the Preferred Stock. As of December 31, 2005 and 2004, no dividends have been declared.
Liquidation
          In the event of any voluntary or involuntary liquidation, dissolution or winding-up of the Company, as defined, the holder of each share of Preferred Stock is entitled to receive, prior to any distribution to common shareholders, the greater of an amount equal to (i) $1.00 per share, plus all unpaid declared dividends, or (ii) the amount per share they would have received if the Preferred shares had been converted to common stock prior to a liquidity event. Liquidation, as defined, would include the sale of the business or the sale of greater than 50% of the common stock of the Company.

Redemption
          The Preferred Stock is not redeemable at the option of the Company or the holders.
Conversion
          The shares of Preferred Stock can, at the election of the holders, at any time, be converted in whole or in part into common shares at a ratio of one-to -one subject to adjustments for stock splits, mergers, consolidations, recapitalizations and or reorganizations.
          Each share of Preferred Stock is automatically converted at the then effective conversion rate immediately upon the consummation of an underwritten public offering, provided that aggregate net proceeds to the Company of such offering are not less than $50,000,000.
Voting
          The holders of Preferred Stock have the same voting rights as the Common stockholders. The two classes of stock shall vote together and not as separate classes.

          Holders of the Company’s Preferred Stock are entitled to anti-dilutive protections and protective class voting rights; including the right to veto sales or mergers of the Company, to prevent amendments to the Company’s certificate of incorporation and to prohibit future sales of Common and Preferred stock.
12. Stockholders’ Equity
Amended and Restated Stockholders Agreement
          At inception, the Company and its common and preferred stockholders entered into a Stockholders Agreement which defines the rights and limitations of its stockholders. The Stockholders Agreement was amended on January 6, 2005.
          The Amended and Restated Stockholders Agreement (the Stockholders Agreement) generally imposes restrictions on the transfer of Company stock and grants the Company and certain of its stockholders certain rights of first refusal and co-sale rights with respect to sales of shares by other stockholders. The Stockholders Agreement also grants to Genstar Capital, LP. (Genstar), one of the primary stockholders, the right to designate all directors of the Company and the right to require other parties to participate, on a pro-rata basis, in any sale of shares by Genstar.
          Regarding shares held by employees of the Company, the Stockholders Agreement grants, to the Company and Genstar, the right to purchase such shares, upon the employees’ termination from the Company, at fair market value, or in the case of termination for cause (as defined in the Stockholders Agreement), at the employees’ cost if lower than the fair market value.
Registration Rights Agreement
          At Inception, the Company and its common stockholders entered into a Registration Rights Agreement which defines the rights to register shares of the Company’s common stock (including shares of common stock issuable upon conversion of shares of the Company’s Series A Preferred Stock).
          The Amended and Restated Registration Rights Agreement (the Registration Agreement) generally grants, to Genstar, the right to require the Company to register its shares of common stock for

Notes to Consolidated Financial Statements — (Continued)
public trading at any time after January 6, 2006. The Registration Agreement also grants other shareholders the right to participate in any registration of common stock required by Genstar. The Registration Agreement imposes restrictions on the sale of the Company shares for a period of 180 days following the effective date of a registration statement or the commencement of a public distribution of shares, provides for certain procedures and requirements for filing of a registration statement with the U.S. Securities and Exchange Commission and provides for certain indemnifications by the Company and its shareholders upon any such registration.
Restricted Common Stock
          The Company’s Board of Directors established the 2004 Equity Incentive Plan (the Plan) that provides for various forms of stock based compensation to independent directors, officers and senior-level employees of the Company. Simultaneous with the establishment of this plan, the Board of Directors authorized and issued 3.3 million shares of restricted common stock to certain independent directors and employees of the Company. The restricted shares issued pursuant to the plan will be service time vested ratably over each of the five years from the date of grant, provided, that the vesting of the restricted shares may accelerate upon the occurrence of certain liquidity events, if approved by the Board of Directors in connection with the transactions. Common stock awarded under the 2004 Equity Incentive Plan is generally subject to restrictions on transfer, repurchase rights, and other limitations and rights as set forth in the Stockholders Agreement and Registration Agreement.
          The Plan permits the Company to grant restricted stock to key employees and other persons who make significant contributions to the success of the Company. The restrictions and vesting schedule for restricted stock granted under the Plan are determined by the Compensation Committee of the Board of Directors. In connection with the November 2004 transaction the Company issued 878,114 shares of restricted common stock with a fair value of $88. In January 2005 351,443 shares with a fair value of $35 were forfeited and 2,788,329 shares of restricted common stock with a fair value of $279 were granted. At December 31, 2005, 3,209,666 shares of unvested restricted stock were outstanding with a fair value of $0.3 million as of the date of the grant. At December 31, 2004, 878,114 shares of unvested restricted stock were outstanding with a fair value of $88 as of the grant date.
          The fair value of the Company’s common stock is determined by the Company’s Board of Directors (the Board) at the time of the restricted common stock grants. In the absence of a public trading market for the Company’s common stock, the Company’s Board considers objective and subjective factors in determining the fair value of the Company’s common stock and related options. Consistent with the guidance provided by the AICPA’s Technical Practice Aid on The Valuation of Privately-held-Company Equity Securities Issued as Compensation (the TPA), such considerations included, but were not limited to, the following factors:
  •  Historical and expected future earnings performance
 
  •  The liquidation preferences and dividend rights of the preferred stock
 
  •  Milestones achieved by the company
 
  •  Marketplace and major competition
 
  •  Market barriers to entry
 
  •  The Company’s workforce and related skills
 
  •  Customer and vendor characteristics
 
  •  Strategic relationships with suppliers
 
  •  Risk factors and uncertainties facing the Company

Predecessor
          For the Predecessor, all historical equity balances are reflected in the combined financial statements as invested capital. The annual net cash flows from the Boston Gear division, the recognition or settlement of intercompany balances of any of the Predecessor entities with Colfax, federal and state income taxes payable or receivable and allocations of balances from Colfax are reflected as contributions from and distributions to affiliates in the consolidated statements of stockholders’ equity.
13. Related-Party Transactions
Kilian Acquisition
          As discussed in Note 3, the Company acquired Kilian through the exchange of preferred and common stock in the Company that was issued to certain preferred and common shareholders of Kilian, the majority of whom were represented by Genstar Capital Partners III, L.P., one of the primary stockholders of the Company.
Management Agreement
          At November 30, 2004, the Company entered into an advisory services agreement with Genstar Capital, L.P. (“Genstar”), whereby Genstar agreed to provide certain management, business strategy, consulting, financial advisory and acquisition related services to the Company. Pursuant to the agreement, the Company will pay to Genstar an annual consulting fee of $1.0 million (payable quarterly, in arrears at the end of each calendar quarter), reimbursement of out-of -pocket expenses incurred in connection with the advisory services and an advisory fee of 2.0% of the aggregate consideration relating to any acquisition or dispositions completed by the Company. The Company recorded $1.0 million and $0.1 million in management fees, included in selling, general and administrative expenses for the year ended December 31, 2005 and for the period from inception through December 31, 2004, respectively. Genstar also received a one-time transaction fee of $4.0 million, and $0.4 million in reimbursement of transaction related expenses, for advisory services it provided in connection with the acquisitions and related financings discussed in Notes 3 and 10, and such amounts are reflected in selling, general and administrative expenses for the period from inception (December  1, 2004) through December 31, 2004. At December 31, 2005, the Company had $0.3 million recorded in accruals and other liabilities as a payable to Genstar in connection with the annual consulting fee, there were no amounts outstanding at December 31, 2004.
Subordinated Notes
          As discussed in Notes 10 & 11, a Preferred Stock holder is the holder of the Subordinated Notes payable. In 2004, the Company recorded $198 thousand of interest expense related to the Notes and no cash payments were made. In 2005, the Company recorded $2.4 million of related interest expense and disbursed $2 million in cash payments to the holder.
Transition Services Agreement
          In connection with the acquisition of the Predecessor operations from Colfax, the Company entered into a transition services agreement with Colfax whereby Colfax agreed to provide the Company with transitional support services. The transition services include the continued access to Colfax’ employee benefit plans through February 2005, the provision of certain accounting, treasury, tax and payroll services through various periods all of which ended by May 2005 and the transition of management oversight of various on-going business initiatives through May 2005. The cost of these services was less than $0.1 million.

Predecessor Related Party Transactions
          Danaher Corporation (Danaher) was related to the Predecessor through common ownership. Revenue from sales of products to Danaher was approximately $0.3 for the eleven months ended November 30, 2004 and $0.3 million for the year ended December 31, 2003. Purchases of products from Danaher amounted to $5.8 million and $7.2 million in the eleven months ending November 30, 2004 and the year ending December 31, 2003, respectively.
          Certain corporate and administrative services were performed for the Predecessor by Colfax personnel. Such services consist primarily of executive management, accounting, legal, tax, treasury and finance. Services performed for the Predecessor by Colfax were allocated to the Predecessor to the extent that they were identifiable, clearly applicable to the Predecessor and factually supported as attributable to the Predecessor. Management believes that this method of allocation is reasonable and it is consistent throughout all periods presented. No significant amounts are included in the Company’s financial statements for such services although certain professional fees including auditing fees have been allocated to the Predecessor results in the Statement of Operations and Comprehensive Income (Loss). Management estimates that these expenses would increase by approximately $1.0 million if the Predecessor was a stand alone entity. In addition, the Predecessor participated in group purchasing arranged by Colfax for costs such as insurance, health care and raw materials. These direct expenses were charged to the Predecessor entities as incurred.
          The Predecessor utilized a materials sourcing operation located in China that was operated by Colfax for the benefit of all affiliated entities. Management estimates that expenses would increase approximately $0.6 million if the Predecessor had to operate this sourcing function on a stand alone basis.
          The Predecessor also participated in the Colfax treasury function whereby funds were loaned to and borrowed from affiliates in the normal course of business. The net amount due to Colfax and its subsidiaries, which are not a component of the Predecessor, are reported as affiliate debt in the Balance Sheet.
14. Concentrations of Credit, Business Risks and Workforce
          Financial instruments, which are potentially subject to concentrations of credit risk, consist primarily of trade accounts receivable. The Company manages this risk by conducting credit evaluations of customers prior to delivery or commencement of services. When the Company enters into a sales contract, collateral is normally not required from the customer. Payments are typically due within thirty days of billing. An allowance for potential credit losses is maintained, and losses have historically been within management’s expectations.
          Credit related losses may occur in the event of non-performance by counterparties to financial instruments. Counterparties typically represent international or well established financial institutions.
          One customer represents 9.4%, 9.0%, 10.3%, and 10.8% of the Company’s and Predecessor’s sales for the year ended December 31, 2005 and the periods December 1, 2004 through December 31, 2004 and January 1, 2004 through November 30, 2004 and the year ended December 31, 2003, respectively. Outstanding accounts receivables from that customer were $3.6 million and $2.7 million at December 31, 2005 and 2004, respectively.
          The Company and its Predecessor operate in a single business segment for the development, manufacturing and sales of mechanical power transmission products. The Company’s chief operating decision maker reviews consolidated operating results to make decisions about allocating resources and

          The net assets of our foreign subsidiaries at December 31, 2005 and 2004 were $49.2 million and $46.8 million, respectively.
          The Company has not provided specific product line sales as our general purpose financial statements do not allow us to readily determine groups of similar product sales.
          Approximately 32.3% of the Company’s labor force (19.3% and 90.1% in the United States and Europe, respectively) is represented by collective bargaining agreements.
15. Predecessor Restructuring, Asset Impairment and Transition Expenses
          On January 1, 2003, the Predecessor adopted SFAS No. 146, “Accounting for Costs Associated with Exit or Disposal Activities”. SFAS No. 146 nullifies EITF  94-3, “Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring)” . Restructuring plans initiated prior to December 31, 2002 are accounted for according to EITF  94-3 while all restructuring actions initiated after December 31, 2002 will be accounted for according to SFAS No. 146. SFAS No. 146 requires that a liability for costs associated with an exit or disposal activity be recognized when the liability is incurred. EITF  94-3 had previously required that a liability for such costs be recognized at the date of the Company’s commitment to an exit or disposal plan. SFAS No. 146 may effect the periods in which costs are recognized although the total amount of costs recognized will be the same as previous accounting guidance.
          Beginning in the fourth quarter of 2002, the Predecessor adopted certain restructuring programs intended to improve operational efficiency by reducing headcount, consolidating its operating facilities and relocating manufacturing and sourcing to low-cost countries. The Predecessor did not exit any of its operating activities and these programs did not reduce sales. The amounts recorded as restructuring charges, asset impairment and transition expenses in the Consolidated Statement of Comprehensive Income (Loss) for the period January 1, 2004 through November 30, 2004 and the year ended

          Certain period costs such as relocation, training, recruiting, duplicative associates and moving costs resulting from restructuring programs amounted to $0.6 million and $9.1 million for the period January 1, 2004 through November 30, 2004 and the year ended December 31, 2003, respectively, were included as a component of transition expense. A summary of Predecessor cost reduction programs follows.
United States Programs
          The speed reducer product line consolidation resulted in the closure of the Florence, KY distribution center, the Louisburg, NC manufacturing facility and the Charlotte, NC manufacturing facility. The three closed locations were moved into a new leased facility in Charlotte, NC. In addition the Norwalk, CA distribution center was downsized and moved into a smaller facility and the engineering and purchasing functions were moved from Quincy, MA to the new Charlotte, NC production facility. This program, other than the payment of accrued severance amounts, was substantially completed in the third quarter of 2003.
          The electronic clutch brake product line consolidation resulted in the closure of the Roscoe, IL manufacturing facility. The high volume turf and garden product line was moved to the Columbia City, IN coil production facility, while the industrial and vehicular product lines were moved into the South Beloit, IL manufacturing facility. This program, other than the payment of accrued severance amounts and certain remaining transition expenses, was substantially completed in the fourth quarter of 2003.
          The sprag clutch product line consolidation resulted in the closure of the LaGrange, IL manufacturing facility. Production was relocated to the Formsprag production facility in Warren, MI. This program, other than the payment of accrued severance amounts, was substantially completed in the fourth quarter of 2002.
          The heavy duty clutch product relocation resulted in the closure of the Waukesha, WI production facility, which was consolidated into the Wichita Falls, TX heavy duty clutch production facility. Engineering support remained in Waukesha in a separate smaller leased facility. This program, other than the payment of accrued severance amounts, was substantially completed in the third quarter of 2003.
          Administrative process streamlining primarily involved the consolidation of the speed reducer and electronic clutch brake product lines customer service function in South Beloit, IL. This program, other than the payment of accrued severance amounts, was substantially completed in the third quarter of 2003.
European and Asian Programs
          The European and Asian electronic clutch brake consolidation resulted in the closure of the Bishop Auckland, United Kingdom manufacturing facility with production being relocated to Angers, France and Shenzhen, China. In addition, customer service and engineering functions were centralized in Angers, France. The two French facilities in Angers and Lemans were also rationalized. The Lemans facility was downsized to focus exclusively on machining operations. All other manufacturing and

General Litigation
          The Company is involved in various pending legal proceedings arising out of the ordinary course of business. None of these legal proceedings is expected to have a material adverse effect on the financial condition of the Company. With respect to these proceedings, management believes that it will prevail, has adequate insurance coverage or has established appropriate reserves to cover potential liabilities. Any costs that management estimates may be paid related to these proceedings or claims are accrued when the liability is considered probable and the amount can be reasonably estimated. There can be no assurance, however, as to the ultimate outcome of any of these matters, and if all or substantially all of these legal proceedings were to be determined adversely to the Company, there could be a material adverse effect on the financial condition of the Company.
          As parent to the Predecessor, Colfax maintained reserves for various legal and environmental matters. Unless a legal or environmental matter of Colfax could be specifically identified as related to the Predecessor, no reserve has been provided for in the Predecessor financial statements. In addition, Colfax has agreed to indemnify the Company for certain pre-existing matters up to agreed upon limits.

          The Predecessor’s capital structure was comprised of contributions from the parent and affiliated companies. There was no common stock associated with the group of entities which comprised the Predecessor. Accordingly there is no respective earnings per share.
18. Subsequent Event (Unaudited)
          On November 7, 2005, we entered into a purchase agreement with the shareholders of Hay Hall Holdings Limited, or Hay Hall, pursuant to which we agreed to acquire all of the outstanding share capital of Hay Hall for $50.3 million subject to certain purchase price adjustments. Under the purchase agreement, the initial aggregate purchase price of $50.3 million to be paid at closing will be subject to a change in working capital adjustment, less debt balances at closing, plus cash balances at closing. We closed the acquisition on February 9, 2006 for $49.2 million. The purchase price is still subject to a change as a result of the finalization of a working capital adjustment in accordance with the terms of the purchase agreement. We will also pay up to $6.0 million of the total purchase price in the form of deferred consideration. At the closing we deposited such deferred consideration into an escrow account for the benefit of the former Hay Hall shareholders. The deferred consideration is represented by a loan note. While the former Hay Hall shareholders will hold the note, their rights will be limited to receiving the amount of the deferred compensation placed in the escrow account. They will have no recourse against the Company unless we take action to prevent or interfere in the release of such funds from the escrow account. At closing, Hay Hall and its subsidiaries became the Company’s direct or indirect wholly owned subsidiaries. Hay Hall is a UK-based holding company established in 1996 that is focused primarily on the manufacture of couplings and clutch brakes. Hay Hall consists of five main businesses that are niche focused and have strong brand names and established reputations within their primary markets.
          The Hay Hall acquisition will be accounted for in accordance with SFAS No. 141. Since the closing date of the Hay Hall acquisition was subsequent to December 31, 2005, the Company’s consolidated financial statements as of that date do not include any amounts related to Hay Hall.
          The Company has not completed its final purchase price allocation. The value of the acquired assets, assumed liabilities and identified intangibles from the acquisition of Hay Hall, as presented below, are based upon management’s estimates of fair value as of the date of the acquisition. However, the

F-34

Notes to Consolidated Financial Statements — (Continued)
goodwill and intangibles recorded in connection with the acquisition of Hay Hall have not yet been allocated across the business units acquired nor have the values been finished. Further, and as discussed above, the final purchase price is subject to certain purchase price adjustments which have not been finalized. The final purchase price allocations will be completed within one year of the acquisition and are not expected to have a material impact on the Company’s financial position or results of operations. The preliminary purchase price allocation is as follows:
           
Total purchase price, including closing costs of approximately $1.7 million
  $ 50,981  
       
Cash and cash equivalents
    441  
Trade receivables
    11,668  
Inventories
    16,989  
Prepaid expenses and other
    1,442  
Property, plant and equipment
    10,509  
Intangible assets
    15,900  
       
 
Total assets acquired
    56,949  
Accounts payable, accrued payroll, and accruals and other current liabilities
    11,862  
Other liabilities
    5,647  
       
 
Total liabilities assumed
    17,509  
       
 
Net assets acquired
    39,440  
       
Excess purchase price over the fair value of net assets acquired
  $ 11,541  
       
          The excess of the purchase price over the fair value of the net assets acquired was recorded as goodwill.
          The estimated amounts recorded as intangible assets consist of the following:
           
Customer relationships
  $ 9,064  
Product technology and patents
    1,589  
       
 
Total intangible assets subject to amortization
    10,653  
       
Trade names and trademarks, not subject to amortization
    5,247  
       
Total intangible assets
  $ 15,900  
       
          Customer relationships, product technology and patents, are subject to amortization over their estimated useful lives which reflects the anticipated periods over which the Company estimates it will benefit from the acquired assets. The estimated useful lives have not been finalized by the Company. The Company anticipates that substantially all of this amortization is deductible for income tax purposes. The Company is considering its options relative to the deductibility of goodwill and is unable at this time to determine what, if any, will be deductible for income tax purposes.

2. Basis of Presentation
          The Company was formed on November 30, 2004 following acquisitions of certain subsidiaries of Colfax Corporation (“Colfax”) and The Kilian Company (“Kilian”).
          The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles. In the opinion of management, the accompanying condensed consolidated financial statements contain all adjustments, which include normal recurring adjustments, necessary to present fairly the consolidated unaudited financial statements as of September 29, 2006 and for the year-to -date periods ended September 29, 2006 and September 30, 2005.
          The Company follows a four-, four-, five-week calendar per quarter with all quarters consisting of thirteen weeks.
          The accompanying unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year-ended December 31, 2005.
          The unaudited pro forma financial information presents the effects of the contemplated conversion of the preferred series A shares to common stock at a ratio of two-to-one and a two-for-one reverse stock split of the common stock outstanding as of the beginning of the period presented.
3. Recent Accounting Pronouncements
          In June 2006, the FASB issued FASB Interpretation No. (“FIN”) 48, “Accounting for Uncertainty in Income Taxes — An Interpretation of FASB Statement No. 109”, which prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN 48 will be effective for fiscal years beginning after December 15, 2006. The Company has not yet completed its evaluation of the impact of adoption on the Company’s financial position or results of operations.
          In September 2006, the Securities and Exchange Commission (“SEC”) issued Staff Accounting Bulletin (“SAB”) No. 108 regarding the process of quantifying financial statement misstatements. SAB No. 108 states that registrants should use both a balance sheet approach and an income statement approach when quantifying and evaluating the materiality of a misstatement. The interpretations in SAB No. 108 contain guidance on correcting errors under the dual approach as well as provide transition guidance for correcting errors. This interpretation docs not change the requirements within SFAS No. 154, “Accounting Changes and Error Corrections-a replacement of APB No. 20 and FASB Statement No. 3,” for the correction of an error on financial statements. SAB No. 108 is effective for annual financial statements covering the first fiscal year ending after November 15, 2006, The Company does not expect the effect to be material.

          In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements.” This standard defines fair value, establishes a framework for measuring fair value in accounting principles generally accepted in the United States of America, and expands disclosure about fair value measurements. This pronouncement applies under other accounting standards that require or permit fair value measurements. Accordingly, this statement does not require any new fair value measurement, This statement is effective for fiscal years beginning after November 15, 2007. and interim periods within those fiscal years. The Company docs not expect the effect to be material.
          In September 2006, the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans-an amendment of FASB Statements No. 87, 88, 106, and 132(R).” This pronouncement requires an employer to recognize the overfunded or underfunded status of a defined benefit postretirement plan (other than a multiemployer plan) as an asset or liability on its statement of financial position. SFAS No. 158 also requires an employer to recognize changes in that funded status in the year in which the changes occur through comprehensive income. In addition, this statement requires an employer to measure the funded status of a plan as of the date of its year-end statement of financial position, with limited exceptions. SFAS No. 158 is effective for fiscal years ending after December 15, 2006. The Company has not yet completed its evaluation of the impact of adoption on the Company’s financial position or results of operations.
4. Net Income Per Share
          Basic earnings per share is based on the weighted average number of common shares outstanding, and diluted earnings per share is based on the weighted average number of common shares outstanding and all dilutive potential common equivalent shares outstanding. Common equivalent shares are included in the per share calculations when the effect of their inclusion would be dilutive.
          The following is a reconciliation of basic to diluted net income per share:

5. Acquisitions
          On November 7, 2005, we entered into a purchase agreement with the shareholders of Hay Hall Holdings Limited, or Hay Hall, pursuant to which we agreed to acquire all of the outstanding share capital of Hay Hall for $50.3 million subject to certain purchase price adjustments. Under the purchase agreement, the initial aggregate purchase price of $50.3 million to be paid at closing is subject to a change in working capital adjustment, less debt balances at closing, plus cash balances at closing. We closed the acquisition on February 10, 2006 for $49.2 million. The purchase price is still subject to a change as a result of the finalization of a working capital adjustment in accordance with the terms of the purchase

agreement. Included in the purchase price was $6.0 million paid in the form of deferred consideration. At the closing we deposited such deferred consideration into an escrow account for the benefit of the former Hay Hall shareholders. The deferred consideration is represented by a loan note. While the former Hay Hall shareholders will hold the note, their rights will be limited to receiving the amount of the deferred consideration placed in the escrow account. They will have no recourse against the Company unless we take action to prevent or interfere in the release of such funds from the escrow account. At closing, Hay Hall and its subsidiaries became the Company’s direct or indirect wholly owned subsidiaries. Hay Hall is a UK-based holding company established in 1996 that is focused primarily on the manufacture of couplings and clutch brakes. Hay Hall consists of five main businesses that are niche focused and have strong brand names and established reputations within their primary markets.
          The Hay Hall acquisition has been accounted for in accordance with SFAS No. 141. The closing date of the Hay Hall acquisition was February 10, 2006, and as such, the Company’s consolidated financial statements reflect Hay Hall’s results of operations only from that date forward.
          The Company has not completed its final purchase price allocation. The preliminary value of the acquired assets, assumed liabilities and identified intangibles from the acquisition of Hay Hall, as presented below, are based upon management’s estimates of fair value as of the date of the acquisition. However, the goodwill and intangibles recorded in connection with the acquisition of Hay Hall have not yet been allocated across the business units acquired nor have the values been finalized. Further, and as discussed above, the final purchase price is subject to certain purchase price adjustments which have not been finalized. The final purchase price allocations will be completed within one year of the acquisition and are not expected to have a material impact on the Company’s financial position or results of operations. The preliminary purchase price allocation is as follows:
           
Total purchase price, including closing costs of approximately $1.9 million
  $ 51,177  
       
Cash and cash equivalents
    441  
Trade receivables
    12,959

Net assets acquired
    43,989  
       
Excess purchase price over the fair value of net assets acquired
    7,188  
       
          The excess of the purchase price over the fair value of the net assets acquired was recorded as goodwill.
          The estimated amounts recorded as intangible assets consist of the following:
         
Customer relationships, subject to amortization
  $ 6,931  
Trade names and trademarks, not subject to amortization
    6,950  
       
Total intangible assets
  $ 13,881

          Customer relationships, product technology and patents, are subject to amortization over their estimated useful lives which reflects the anticipated periods over which the Company estimates it will benefit from the acquired assets. The estimated useful lives have not been finalized by the Company. The Company anticipates that substantially all of this amortization is deductible for income tax purposes. The Company is considering its options relative to the deductibility of goodwill and is unable at this time to determine what, if any, will be deductible for income tax purposes.
          On May 18, 2006, we entered into a purchase agreement with the shareholders of Bear Linear LLC, or Bear, to purchase substantially all of the assets of the company for $5.0 million. Approximately $3.5 million was paid at closing and the remaining $1.5 million is payable over the next 2.5 years. One of Bear’s selling shareholders is a direct relative of one of the Company’s directors. Bear manufacturers high value-added linear actuators for mobile off-highway and industrial applications.
          The Bear acquisition has been accounted for in accordance with SFAS No. 141. The closing date of the Bear acquisition was May 18, 2006, and as such, the Company’s consolidated financial statements reflect Bear’s results of operations only from that date forward.
          Bear had approximately $0.5 million of net assets at closing consisting primarily of accounts receivable, inventory, fixed assets and accounts payable and accrued liabilities. We recorded the $4.2 million excess purchase price over the fair value of the net assets acquired as goodwill. The Company has not completed its final purchase price allocation, but will complete it within one year of the acquisition and it is not expected to have a material impact on the Company’s financial position or results of operations.
          The following table sets forth the unaudited pro forma results of operations of the Company for the year-to -date periods ended September 29, 2006 and September 30, 2005 as if the Company had acquired Hay Hall and Bear Linear as of January 1, 2005. The pro forma information contains the actual operating results of the Company, Bear Linear, and Hay Hall with the results prior to May 18, 2006 for Bear Linear, and February 10, 2006 for Hay Hall adjusted to include the pro forma impact of (i) the elimination of additional expense as a result of the fair value adjustment to inventory recorded in connection with the Acquisition; (ii) additional interest expense associated with debt issued on February 8, 2006; (iii) the elimination of intercompany sales between Hay Hall and the Company; (iv) additional expense as a result of estimated amortization of identifiable intangible assets; (v) and an adjustment to the tax provision for the tax effect of the above adjustments. These pro forma amounts do not purport to be indicative of the results that would have actually been obtained if the acquisitions occurred as of January 1, 2005 or that may be obtained in the future.

9. Warranty Costs
          Estimated expenses related to product warranties are accrued at the time products are sold to customers. Estimates are established using historical information as to the nature, frequency, and average costs of warranty claims. Changes in the carrying amount of accrued product warranty costs for the year-to -date periods ended September 29, 2006 and September 30, 2005 are as follows:
                 
    September 29, 2006   September 30, 2005
         
Balance at beginning of period
  $ 1,876     $ 1,528  
Accrued warranty costs
    1,365       979  
Payments and adjustments
    1,072       (957 )
             
Balance at end of period
  $ 2,169     $ 1,550  
             
10. Income Taxes
          The effective tax rates recorded for the year-to -date periods ended September 29, 2006 and September 30, 2005 were recorded based upon management’s best estimate of the effective tax rates for the entire respective years. The change in the effective tax rate from 50.7% for the first nine months of 2005 to 37.8% for the same period in 2006 is the result of the Hay Hall acquisition and a greater amount of interest expense disallowed for income tax benefit. In addition, there was a greater proportion of taxable income in jurisdictions possessing lower statutory tax rates. The 2006 tax rate differs from the statutory rate due to the impact of non-U.S.  tax rates and permanent differences.
11. Pension and Other Employee Benefits
Defined Benefit (Pension) and Postretirement Benefit Plans
          The Company’s wholly owned subsidiary, Altra Industrial Motion, Inc. (Altra Industrial), sponsors various defined benefit (pension) and postretirement (medical and life insurance coverage) plans for certain, primarily unionized, active employees (those in the employment of Altra Industrial at or hired since November 30, 2004). Additionally, Altra Industrial assumed all post-employment and post-retirement welfare benefit obligations with respect to active U.S. employees.
          The following table represents the components of the net periodic benefit cost associated with the respective plans for the quarter and year-to -date periods ended September 29, 2006 and September 30, 2005:

          Altra Industrial revises its other post-retirement benefit estimates and assumptions annually in the third quarter and adjusts its year to date expense accordingly.
          In December 2003, Congress passed the “Medicare Prescription Drug Improvement and Modernization Act of 2003” (the Act) that reformed Medicare in such a way that Altra Industrial may have been eligible to receive subsidies for certain prescription drug benefits that are incurred on behalf of plan participants. There has been no impact on Altra Industrial’s plans as either prescription drug coverage is not offered past the age of 65 or we have not applied for any subsidy. Accordingly, the amounts recorded and disclosed in these financial statements do not reflect any amounts related to this Act.
          In May, 2006 Altra Industrial renegotiated its contract with the labor union at its South Beloit, IL manufacturing facility. As a result of the renegotiation, participants in Altra Industrial’s pension plan cease to accrue additional benefits starting July 3, 2006. Additionally, the other post retirement benefit plan has been terminated for all eligible participants who have not retired, or given notice to retire in 2006, by August 1, 2006. Altra Industrial recognized a non-cash gain associated with the curtailment of this plan in the third quarter of 2006 of $3.8 million.
11. Financing Arrangements
Revolving Credit Agreement
          At November 30, 2004, Altra Industrial entered into an agreement for up to $30 million of revolving borrowings from a commercial bank (the Revolving Credit Agreement), subject to certain limitations resulting from the requirement of Altra Industrial to maintain certain levels of collateralized assets, as defined in the Revolving Credit Agreement. Altra Industrial may use up to $10 million of its availability under the Revolving Credit Agreement for standby letters of credit issued on its behalf, the issuance of which will reduce the amount of borrowings that would otherwise be available to Altra Industrial. Altra Industrial may re-borrow any amounts paid to reduce the amount of outstanding borrowings; however, all borrowings under the Revolving Credit Agreement must be repaid in full as of November 30, 2009.
          Substantially all of Altra Industrial’s assets have been pledged as collateral against outstanding borrowings under the Revolving Credit Agreement. The Revolving Credit Agreement requires Altra Industrial to maintain a minimum fixed charge coverage ratio (when availability under the line falls below $12.5 million) and imposes customary affirmative covenants and restrictions on Altra Industrial. The Company was in compliance with all requirements of the Revolving Credit Agreement at September 29, 2006.

Notes to Unaudited Condensed Consolidated Interim Financial Statements — (Continued)
          There were no borrowings under the Revolving Credit Agreement at September 29, 2006 and December 31, 2005, however, as of both dates, the lender had issued $2.4 million of outstanding letters of credit on behalf of Altra Industrial.
9% Senior Secured Notes
          At November 30, 2004, Altra Industrial issued 9% Senior Secured Notes, with a face value of $165 million. Interest on the Senior Secured Notes is payable semiannually, in arrears, on June 1 and December 1 of each year, beginning June 1, 2005, at an annual rate of 9%. The effective interest rate on the Senior Secured Notes is approximately 10.0%, after consideration of the amortization of $6.6 million related to initial offer discounts (included in long-term debt) and $2.8 million of deferred financing costs (included in other assets). The Senior Secured Notes mature on December 1, 2011 unless previously redeemed by the Company.
          The Senior Secured Notes are guaranteed by Altra Industrial’s U.S. domestic subsidiaries and are secured by a second priority lien, subject to first priority liens securing the Revolving Credit Agreement, on substantially all of Altra Industrial’s assets. The Senior Secured Notes contain numerous terms, covenants and conditions, which impose substantial limitations on Altra Industrial. Altra Industrial was in compliance with all covenants of the Senior Secured Notes at September 29, 2006.
11.25% Senior Notes
          At February 8, 2006, Altra Industrial issued 11.25% Senior Notes, with a face value of £33 million. Interest on the Senior Notes is payable semiannually, in arrears, on August 15 and February 15 of each year, beginning August 15, 2006, at an annual rate of 11.25%. The effective interest rate on the Senior Notes is approximately 11.7%, after consideration of the $2.5 million of deferred financing costs (included in other assets). The Senior Notes mature on February 15, 2013 unless previously redeemed by the Company.
          The Senior Notes are guaranteed on a senior unsecured basis by Altra Industrial’s U.S. domestic subsidiaries. The Senior Notes contain numerous terms, covenants and conditions, which impose substantial limitations on Altra Industrial. Altra Industrial was in compliance with all covenants of the Senior Notes at September 29, 2006.
     Subordinated Notes
          At November 30, 2004, the Company executed an agreement with a stockholder to obtain $14.0 million of unsecured subordinated financing (the Subordinated Notes). The Subordinated Notes were issued at par value and mature on November 30, 2019. Interest accrues at an annual rate of 17% and is payable quarterly in full or payment-in -kind (PIK). For the periods presented, the Company has paid all interest in full. As of September 29, 2006 and December 31, 2005, there was $0.1 million and $0.6 million of accrued interest included in accruals and other liabilities in the accompanying balance sheet.
          The Subordinated notes become callable by the lender on December 1, 2011 or upon full payment of the 9% Senior Secured notes discussed below. The lender also has the right to demand payment at 101% upon change of control. The Company may elect to redeem the Subordinated notes at any time in whole or in part. Payments made prior to November 30, 2006 will incur a 6% prepayment penalty. This prepayment penalty decreases by 1% on every subsequent anniversary date. During 2006 the Company prepaid $12.5 million of the Subordinated Notes, incurring a prepayment penalty of approximately $0.8 million.

          The Company incurred approximately $0.3 million in fees associated with the issuance of the Subordinated Notes that are capitalized as deferred financing costs included in other assets in the accompanying balance sheet. These costs will be amortized through November 2011 as a component of interest expense.
          The Subordinated Notes impose customary affirmative covenants and restrictions on the Company, including the delivery of timely financial information to the lender. The Company was in compliance with all covenant requirements as of September 29, 2006.
Mortgage
          In June, 2006, the Company’s German subsidiary entered into a mortgage on their building in Heidelberg, Germany, with a local bank. The mortgage has a principal of 2.0 million, an interest rate of 5.75% and is payable in monthly installments over 15 years.
Capital Leases
          The Company leases certain equipment under capital lease arrangements, whose obligations are included in both short-term and long-term debt. Capital lease obligations amounted to approximately $2.1 million and $0.3 million at September 29, 2006 and December 31, 2005, respectively. Assets under capital leases are included in property, plant and equipment with the related amortization recorded as depreciation expense.
12. Convertible Preferred Stock
          The Company has authorized 40,000,000 shares of Series A Convertible Preferred Stock (the Preferred), 35,500,000 of which was outstanding as of September 29, 2006 and December 31, 2005, respectively. A Preferred holder is also the holder of the Company’s Subordinated Notes, discussed in Note 10. The Preferred Stock holders are entitled to the following rights:
Dividends
          The holders of the outstanding Preferred Stock are entitled to receive, when and if declared by the Board, non-cumulative cash dividends at an annual rate of $0.08 per share of the Preferred Stock. As of September 29, 2006 and December 31, 2005, no dividends have been declared.
Liquidation
          In the event of any voluntary or involuntary liquidation, dissolution or winding-up of the Company, as defined, the holder of each share of Preferred Stock is entitled to receive, prior to any distribution to common shareholders, the greater of an amount equal to (i) $1.00 per share, plus all unpaid declared dividends, or (ii) the amount per share they would have received if the Preferred shares had been converted to common stock prior to a liquidity event. Liquidation, as defined, would include the sale of the business or the sale of greater than 50% of the common stock of the Company.

ALTRA HOLDINGS, INC.
Notes to Unaudited Condensed Consolidated Interim Financial Statements — (Continued)
Redemption
          The Preferred Stock is not redeemable at the option of the Company or the holders.
Conversion
          The shares of Preferred Stock can, at the election of the holders, at any time, be converted in whole or in part into common shares at a ratio of one-to -one subject to adjustments for stock splits, mergers, consolidations, recapitalizations and or reorganizations.
          Each share of Preferred Stock is automatically converted at the then effective conversion rate immediately upon the consummation of an underwritten public offering, provided that aggregate net proceeds to the Company of such offering are not less than $50,000,000.
Voting
          The holders of Preferred Stock have the same voting rights as the Common stockholders. The two classes of stock shall vote together and not as separate classes. Each shareholder of Preferred Stock is entitled to one vote per each share of Common Stock into which the Preferred Stock could then be converted.
Protective Provision
          Holders of the Company’s Preferred Stock are entitled to anti-dilutive protections and protective class voting rights; including the right to veto sales or mergers of the Company, to prevent amendments to the Company’s certificate of incorporation and to prohibit future sales of Common and Preferred stock.
13. Stockholders’ Equity
Amended and Restated Certificate of Incorporation
          At inception, the Company and its common and preferred stockholders entered into a Stockholders Agreement which defines the rights and limitations of its stockholders. The Stockholders Agreement was amended on January 6, 2005.
          The Amended and Restated Stockholders Agreement (the Stockholders Agreement) generally imposes restrictions on the transfer of Company stock and grants the Company and certain of its stockholders certain rights of first refusal and co-sale rights with respect to sales of shares by other stockholders. The Stockholders Agreement also grants to Genstar Capital, LP. (Genstar), one of the primary stockholders, the right to designate all directors of the Company and the right to require other parties to participate, on a pro-rata basis, in any sale of shares by Genstar.
          Regarding shares held by employees of the Company, the Stockholders Agreement grants, to the Company and Genstar, the right to purchase such shares, upon the employees’ termination from the Company, at fair market value, or in the case of termination for cause (as defined in the Stockholders Agreement), at the employees’ cost if lower than the fair market value.
Registration Rights Agreement
          At Inception, the Company and its common stockholders entered into a Registration Rights Agreement which defines the rights to register shares of the Company’s common stock (including shares of common stock issuable upon conversion of shares of the Company’s Series A Preferred Stock).
          The Amended and Restated Registration Rights Agreement (the Registration Agreement) generally grants, to Genstar, the right to require the Company to register its shares of common stock for

Notes to Unaudited Condensed Consolidated Interim Financial Statements — (Continued)
public trading at any time after January 6, 2006. The Registration Agreement also grants other shareholders the right to participate in any registration of common stock required by Genstar. The Registration Agreement imposes restrictions on the sale of the Company shares for a period of 180 days following the effective date of a registration statement or the commencement of a public distribution of shares, provides for certain procedures and requirements for filing of a registration statement with the U.S. Securities and Exchange Commission and provides for certain indemnifications by the Company and its shareholders upon any such registration.
Restricted Common Stock
          The Company’s Board of Directors established the 2004 Equity Incentive Plan (the Plan) that provides for various forms of stock based compensation to independent directors, officers and senior-level employees of the Company. Simultaneous with the establishment of this plan, the Board of Directors authorized and issued 3.3 million shares of restricted common stock to certain independent directors and employees of the Company. The restricted shares issued pursuant to the plan will be service time vested ratably over each of the five years from the date of grant, provided, that the vesting of the restricted shares may accelerate upon the occurrence of certain liquidity events, if approved by the Board of Directors in connection with the transactions. Common stock awarded under the 2004 Equity Incentive Plan is generally subject to restrictions on transfer, repurchase rights, and other limitations and rights as set forth in the Stockholders Agreement and Registration Agreement.
          The Plan permits the Company to grant restricted stock to key employees and other persons who make significant contributions to the success of the Company. The restrictions and vesting schedule for restricted stock granted under the Plan are determined by the Compensation Committee of the Board of Directors. Compensation expense recorded during the nine months ended September 29, 2006 was $0.4 million. Compensation expense is recognized on a straight-line basis over the vesting period.
          The following table sets forth the activity of the Company’s restricted stock grants to date:
                 
        Weighted-average
        grant date fair
    Shares   value

Restricted shares outstanding September 29, 2006
    3,345,511     $ 1.57  
             
          Total remaining unrecognized compensation cost is approximately $4.8 million as of September 29, 2006 and will be recognized over a weighted average remaining period of three years.
          The fair value of the Company’s common stock is determined by the Company’s Board of Directors (the Board) at the time of the restricted common stock grants. In the absence of a public trading market for the Company’s common stock, the Company’s Board considers objective and subjective factors in determining the fair value of the Company’s common stock and related options. Consistent with the guidance provided by the AICPA’s Technical Practice Aid on The Valuation of Privately-held-

Company Equity Securities Issued as Compensation (the TPA), such considerations included, but were not limited to, the following factors:
  •  Historical and expected future earnings performance
 
  •  The liquidation preferences and dividend rights of the preferred stock
 
  •  Milestones achieved by the company
 
  •  Marketplace and major competition
 
  •  Market barriers to entry
 
  •  The Company’s workforce and related skills
 
  •  Customer and vendor characteristics
 
  •  Strategic relationships with suppliers
 
  •  Risk factors and uncertainties facing the Company
14. Related-Party Transactions
Kilian Acquisition
          The Company acquired Kilian through the exchange of preferred and common stock in the Company that was issued to certain preferred and common shareholders of Kilian, the majority of whom were represented by Genstar Capital Partners III, L.P., one of the primary stockholders in the Company.
Management Agreement
          At November 30, 2004, the Company entered into an advisory services agreement with Genstar Capital, L.P. (“Genstar”), whereby Genstar agreed to provide certain management, business strategy, consulting, financial advisory and acquisition related services to the Company. Pursuant to the agreement, the Company will pay to Genstar an annual consulting fee of $1.0 million (payable quarterly, in arrears at the end of each calendar quarter), reimbursement of out-of -pocket expenses incurred in connection with the advisory services and an advisory fee of 2.0% of the aggregate consideration relating to any acquisition or dispositions completed by the Company. The Company recorded $0.8 million in management fees, included in selling, general and administrative expenses for each of the year-to -date periods ended September 29, 2006 and September 30, 2005. Genstar also received a one-time transaction fee of $1.0 million, for advisory services it provided in connection with the Hay Hall acquisition and related financings discussed in Notes 5 and 11, and such amounts are reflected in selling, general and administrative expenses for the year-to -date period ended September 29, 2006. There were no amounts payable to Genstar at September 29, 2006 or September 30, 2005.
Subordinated Notes
          The holder of the Subordinated Notes is also a Preferred Stock holder. For the nine months ended September 29, 2006, the Company expensed $1.5 million and disbursed $14.6 million in cash to the holder. For the nine months ended September 30, 2005, the Company expensed $1.8 million in related interest and disbursed $1.4 million in cash to the holder.

15. Concentrations of Credit, Business Risks and Workforce
          Financial instruments, which are potentially subject to concentrations of credit risk, consist primarily of trade accounts receivable. The Company manages this risk by conducting credit evaluations of customers prior to delivery or commencement of services. When the Company enters into a sales contract, collateral is normally not required from the customer. Payments are typically due within thirty days of billing. An allowance for potential credit losses is maintained, and losses have historically been within management’s expectations.
          Credit related losses may occur in the event of non-performance by counterparties to financial instruments. Counterparties typically represent international or well established financial institutions.
          No one customer represented 10% or more of the Company’s sales for the year-to -date periods ended September 29, 2006 and September 30, 2005.
          Approximately 23.4% of the Company’s labor force (17.9% and 46.3% in the United States and Europe, respectively) is represented by collective bargaining agreements.
16. Geographic Information
          The Company operates in a single business segment for the development, manufacturing and sales of mechanical power transmission products. The Company’s chief operating decision maker reviews consolidated operating results to make decisions about allocating resources and assessing performance for the entire Company. Net sales to third parties and property, plant and equipment by geographic region are as follows (in thousands):
                                   
    Net Sales   Property, Plant
        and Equipment
        Year-to-

Total
  $ 347,511     $ 273,491     $ 81,511     $ 66,393  
                         
          Net sales to third parties are attributed to the geographic regions based on the country in which the shipment originates. Amounts attributed to the geographic regions for long-lived assets are based on the location of the entity, which holds such assets.
          The net assets of our foreign subsidiaries at September 29, 2006 and December 31, 2005 were $49.7 million and $49.2 million, respectively.
          The Company has not provided specific product line sales as our general purpose financial statements do not allow us to readily determine groups of similar product sales.

17. Commitments and Contingencies
General Litigation
          The Company is involved in various pending legal proceedings arising out of the ordinary course of business. None of these legal proceedings is expected to have a material adverse effect on the financial condition of the Company. With respect to these proceedings, management believes that it will prevail, has adequate insurance coverage or has established appropriate reserves to cover potential liabilities. Any costs that management estimates may be paid related to these proceedings or claims are accrued when the liability is considered probable and the amount can be reasonably estimated. There can be no assurance, however, as to the ultimate outcome of any of these matters, and if all or substantially all of these legal proceedings were to be determined adversely to the Company, there could be a material adverse effect on the financial condition of the Company.
          Colfax maintained reserves for various legal and environmental matters and has agreed to indemnify the Company for certain pre-existing matters up to agreed upon limits.

B11 2BE
          We have audited the accompanying consolidated balance sheet of Hay Hall Holdings Limited as of December 31, 2005 and the related consolidated profit and loss account and cash flows for the year then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audit.
          We conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.
          In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Hay Hall Holdings Limited at December 31, 2005, and the results of its consolidated profit and loss account and its cash flows for the year then ended in conformity with accounting principles generally accepted in the United Kingdom, which differ in certain respects from those followed in the United States, as described in Note 28 to the financial statements.

Notes to Accounts
1 Accounting policies
          The principal accounting policies are set out below. They have all been applied consistently throughout the period.
a)     Basis of accounting
          The accounts have been prepared under the historical cost convention and in accordance with applicable accounting standards. The Group has adopted the full accounting requirements of FRS17 — Retirement Benefits in the 2005 accounts and comparative figures for 2004 have been restated accordingly. The change in accounting policy had the effect of increasing group profits after tax for the year by £75,000, and decreasing group shareholders’ funds by £2,069,000.
b)     Accounting period
          The financial statements cover the period for the year ended 31 December 2005.
c)     Basis of consolidation
          The Group accounts consolidate the accounts of Hay Hall Holdings Limited and its material subsidiary undertakings drawn up to 31 December. The results of subsidiaries acquired or sold are consolidated for the periods from or to the date on which control passed. Acquisitions are accounted for under the acquisition method.
          As permitted by Section 230 of the Companies Act 1985, no profit and loss account is presented in respect of Hay Hall Holdings Limited. The retained profit for the financial period of the parent company was £Nil.
d)     Goodwill
          Goodwill arising on acquisitions is capitalised and written off on a straight line basis over its useful economic life which is a maximum of twenty years. Provision is made for any impairment.
e)     Tangible fixed assets
          Tangible fixed assets are shown at cost, net of depreciation and any provision for impairment. Depreciation is provided on all tangible fixed assets other than freehold land, at rates calculated to write off the cost, less estimated residual value, of fixed assets on a straight-line basis over their expected useful lives, as follows:
     
Freehold buildings
  2% to 3 1 / 3 % per annum
Improvements to short leasehold premises
  Over term of lease
Plant and machinery and equipment
  4% to 33 1 / 3 % per annum
          Residual value is calculated on prices prevailing at the date of acquisition or revaluation.
          Where depreciation charges are increased following a revaluation, an amount equal to the increase is transferred annually from the revaluation reserve to the profit and loss account as a movement on reserves. On the disposal or recognition of a provision for impairment of a revalued fixed asset, any related balance remaining in the revaluation reserve is also transferred to the profit and loss account as a movement on reserves.

F-59


Table of Contents

Notes to Accounts — (Continued)
f)     Investments
          Fixed asset investments are shown at cost less provision for impairment.
g)     Stocks
          Stocks are stated at the lower of cost and net realisable value. Cost includes materials, direct labour and an attributable proportion of manufacturing overheads based on normal levels of activity. Net realisable value is based on estimated selling price, less further costs expected to be incurred to completion and disposal. Provision is made for obsolete, slow-moving or defective items where appropriate.
h)     Taxation
          Corporation tax payable is provided on taxable profits at the current rate. Payment is made in certain cases by group companies for group relief surrendered to them.
          Deferred tax is recognised in respect of all timing differences that have originated but not reversed at the balance sheet date where transactions or events that result in an obligation to pay more tax in the future or a right to pay less tax in the future have occurred at the balance sheet date. Timing differences are differences between the company’s taxable profits and its results as stated in the financial statements that arise from the inclusion of gains and losses in tax assessments in periods different from those in which they are recognised in the financial statements.
          A net deferred tax asset is regarded as recoverable and therefore recognised only when, on the basis of all available evidence, it can be regarded as more likely than not that there will be suitable taxable profits from which the future reversal of the underlying timing differences can be deducted.
          Deferred tax is not recognised when fixed assets are revalued unless by the balance sheet date there is a binding agreement to see the revalued assets and the gain or loss expected to arise on sale has been recognised in the financial statements. Neither is deferred tax recognised when fixed assets are sold and it is more likely than not that the taxable gain will be rolled over, being charged to tax only if and when the replacements assets are sold.
          Deferred tax is recognised in respect of the retained earnings of overseas subsidiaries and associates only to the extent that, at the balance sheet date, dividends have been accrued as receivable or a binding agreement to distribute past earnings in future has been entered into by the subsidiary or associates.
          Deferred tax is measured at the average tax rates that are expected to apply in the periods in which the timing differences are expected to reverse, based on tax rates and laws that have been enacted or substantively enacted by the balance sheet date. Deferred tax is measured on a non-discounted basis.
i)     Foreign currency
          Transactions in foreign currencies are recorded at the rate of exchange at the date of the transaction or, if hedged, at the forward contract rate. Monetary assets and liabilities denominated in foreign currencies at the balance sheet date are reported at the rates of exchange prevailing at that date or, if appropriate, at the forward contract rate. Any gain or loss arising from a change in exchange rates subsequent to the date of the transaction is included as an exchange gain or loss in the profit and loss account.
          The results of overseas operations are translated at the average rates of exchange during the period and their balance sheets at the rates ruling at the balance sheet date. Exchange differences arising on translation of the opening net assets and on foreign currency borrowings, to the extent that they hedge the group’s investment in such operations, are dealt with through reserves. All other exchange differences are included in the profit and loss account.

j)     Leases
          Assets held under finance leases, which confer rights and obligations similar to those attached to owned assets, are capitalised as tangible fixed assets and are depreciated over the shorter of the lease terms and their useful lives. The capital elements of future lease obligations are recorded as liabilities, while the interest elements are charged to the profit and loss account over the period of the leases to produce a constant rate of charge on the balance of capital repayments outstanding. Hire purchase transactions are dealt with similarly, except that assets are depreciated over their useful lives.
          Rentals under operating leases are charged on a straight-line basis over the lease term, even if the payments are not made on such a basis.
k)     Turnover
          Turnover represents amounts receivable for goods and services provided in the normal course of business, net of trade discounts, VAT and other sales related taxes.
l)     Pension costs
          Contributions to the group’s defined contribution pension scheme are charged to the profit and loss account in the year in which they become payable.
          The difference between the fair value of the assets held in the group’s defined benefit pension scheme and the scheme’s liabilities measures on an actuarial basis using the projected unit method are recognised in the group’s balance sheet as a pension asset or liability as appropriate. The carrying value of any resulting pension scheme asset is restricted to the extent that the group is able to recover the surplus either through reduced contributions in the future or through refunds from the scheme. The pension scheme balance is recognised net of any related deferred tax balance.
          Charges in the defined benefit scheme asset or liability arising from factors other than cash contribution by the group are charged to the profit and loss account or the statement of total recognised gains and losses in accordance with FRS17 ‘Retirement benefits’.
m)     Finance costs
          Finance costs of debt and non-equity shares are recognised in the profit and loss account over the term of such instruments at a constant rate on the carrying amount. Where the finance costs for non-equity shares are not equal to the dividends on these instruments, the difference is also accounted for in the profit and loss account as an appropriation of profits.
n)     Debt
Debt is initially stated at the amount of the net proceeds after deduction of issue costs. The carrying amount is increased by the finance cost in respect of the accounting year and reduced by payments made in the year.

28 Summary of differences between accounting principles in the United Kingdom and the United State of America
          The consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United Kingdom (“UK GAAP”) which differs in certain respects from accounting principles in the United States of America (“US GAAP”).

     (a) Goodwill Amortization
Under UK GAAP, goodwill is recorded at its actual cost in sterling, or at the original foreign currency amount translated at the exchange rate applying on the acquisition date. Goodwill is then held in the currency of the acquiring entity at historic cost and amortized at a rate calculated to write off its value on a straight-line basis over its estimated useful life, which is currently considered to be twenty years. Furthermore, goodwill is reviewed for impairment if events or changes in circumstances indicate that the carrying value may not be recoverable.
Under US GAAP, goodwill is not amortized but rather tested at least annually for impairment. Furthermore, goodwill is denominated in the functional currency of the acquired entity. Consequently, the goodwill is retranslated at each period end at the closing rate of exchange.
     (b) Tangible Assets
Under UK GAAP, certain assets may be revalued, while under US GAAP, they are shown as historical cost.
1. Balance sheet and profit and loss account presentation
General
The format of a balance sheet prepared in accordance with UK GAAP differs in certain respects from US GAAP. UK GAAP requires assets to be presented in ascending order of liquidity whereas US GAAP assets are presented in descending order of liquidity. In addition, current assets under UK GAAP include amounts that fall due after more than one year, whereas under US GAAP, such assets are classified as non-current assets.
2. Consolidated statement of cashflow
The consolidated statement of cash flow prepared under UK GAAP presents substantially the same information as that required under US GAAP. Cash flow under UK GAAP represents increases or decreases in “cash”, which comprises cash in hand, deposits repayable on demand and bank overdrafts. Under US GAAP, cash flow represents increases or decreases in “cash and Cash equivalents”, which includes short-term, highly liquid investments with original maturities of less than three months, and excludes bank overdrafts.

Table of Contents

Notes to Accounts — (Continued)
Under UK GAAP, cash flows are presented separately for operating activities, equity dividends, returns on investment and servicing of finance, taxation, capital expenditure and financial investment, acquisitions and disposals, management of liquid resources and financing activities. Under US GAAP, only three categories of cash flow activity are presented, being cash flows relating to operating activities, investing activities and financing activities. Cash flows from taxation and returns on investments and servicing of finance, with the exception of servicing of members’ finance, are included as operating.
The following statements summarize the statements of cash flows as if they had been presented in accordance with US GAAP, and include the adjustments that reconcile cash and cash equivalents under US GAAP to cash and short term deposits under UK GAAP.

Item 14. Indemnification of Directors and Officers
          The following is a summary of the statute, charter and bylaw provisions or other arrangements under which the registrant’s directors and officers are insured or indemnified against liability in their capacities as such. All the directors and officers of the registrant are covered by insurance policies maintained and held in effect by Altra Holdings, Inc. against certain liabilities for actions taken in their capacities as such, including liabilities under the Securities Act. In addition, three of our directors, Messrs. Conte, Paterson and Gold, are also indemnified by insurance policies maintained and held by Genstar Capital.
Section 145 of Delaware General Corporation Law.
          Altra Holdings, Inc., is incorporated under the laws of the State of Delaware. Section 145 of the Delaware General Corporation Law, or DGCL, provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit, or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful.
          Section 145 also provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending, or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a

II-1


Table of Contents

manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery of Delaware or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery of Delaware or such other court shall deem proper.
          To the extent that a present or former director or officer of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to above, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith; provided that indemnification provided for by Section 145 or granted pursuant thereto shall not be deemed exclusive of any other rights to which the indemnified party may be entitled; and a Delaware corporation shall have power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity or arising out of such person’s status as such whether or not the corporation would have the power to indemnify such person against such liabilities under Section 145.
Certificate of Incorporation Provisions on Indemnification.
          The Certificate of Incorporation of Altra Holdings, Inc. provides that a director of the corporation shall not be personally liable to either the corporation or any of its stockholder for monetary damages for a breach of fiduciary duty except for (i) breaches of the duty of loyalty to the corporation or its stockholders, (ii) acts or omissions not in good faith or involving intentional misconduct or knowing violation of the law, (iii) as required by Section 174 of the DGCL or (iv) a transaction resulting in an improper personal benefit. In addition the corporation has the power to indemnify any person serving as a director, officer or agent of the corporation to the fullest extent permitted by law.
By-law Provisions on Indemnification.
          The By-laws of Altra Holdings, Inc. provide generally that the corporation has the power to indemnify its directors, officers, employees and agents who are or were a party, or threatened to be made a party, to any threatened, pending, or contemplated action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation), by reason of the fact that such person is or was the director, officer, employee or agent of the corporation, or is or was serving in such a position at its request of any other corporation, partnership, joint venture, trust or other enterprise.

SCHEDULE I — CONDENSED FINANCIAL INFORMATION OF REGISTRANT — (Continued)
NOTES TO CONDENSED FINANCIAL STATEMENTS
1.     Basis of Presentation
          Altra Holdings, Inc. (Parent Company) was formed on December 1, 2004. Therefore, results of operations and cash flows are only presented for periods subsequent to that date. In the parent-company-only financial statements, the Company’s investment in subsidiaries is stated at cost plus equity in undistributed earnings of subsidiaries since the date of acquisition. The parent-company-only financial statements should be read in conjunction with the Company’s consolidated financial statements.
2.     Restriction
          The Company’s wholly owned subsidiary, Altra Industrial Motion, Inc. (Altra Industrial), issued 9% senior secured notes in an aggregate principal amount of $165.0 million due in 2011 (the Notes). The Notes are secured on a second-priority basis, by security interests in substantially all of the Company’s assets (other than certain excluded assets) and are unconditionally guaranteed by all existing and future domestic restricted subsidiaries. The indenture governing the Notes contains covenants which restrict the Company’s restricted subsidiaries. These restrictions limit or prohibit, among other things, their ability to: incur additional indebtedness; repay subordinated indebtedness prior to stated maturities; pay dividends on or redeem or repurchase stock or make other distributions; make investments or acquisitions; sell certain assets or merge with or into other companies; sell stock in the Company’s subsidiaries; and create liens. The net assets of the domestic restricted subsidiaries was $176.7 million and $157.9 million at December 31, 2005 and 2004, respectively.

Item 17. Undertakings
          Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to Item 14 above, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issues.
          The undersigned Registrant hereby undertakes:
            (1) That for purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.
 
            (2) That for the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 
            (3) To provide to the underwriters at the closing specified in the Underwriting Agreement, certificates in such denomination and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.
 
            (4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser, if the Registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.
 
            (5) That, for the purpose of determining liability of the Registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, in a primary offering of securities of the undersigned Registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned Registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:
            i. Any preliminary prospectus or prospectus of the undersigned Registrant relating to the offering required to be filed pursuant to Rule 424;

II-15


Table of Contents

            ii. Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned Registrant or used or referred to by the undersigned Registrant;
 
            iii. The portion of any other free writing prospectus relating to the offering containing material information about the undersigned Registrant or its securities provided by or on behalf of the undersigned Registrant; and
 
            iv. Any other communication that is an offer in the offering made by the undersigned Registrant to the purchaser.

Ladies and Gentlemen:

Altra Holdings, Inc., a Delaware corporation (the "Company"), and the persons listed in Schedule B hereto (the "Selling Shareholders"), confirm their respective agreements with Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch") and each of the other Underwriters named in Schedule A hereto (collectively, the "Underwriters," which term shall also include any underwriter substituted as hereinafter provided in Section X hereof), for whom Merrill Lynch is acting as representative (in such capacity, the "Representative"), with respect to (i) the sale by the Company and the Selling Shareholders, acting severally and not jointly, and the purchase by the Underwriters, acting severally and not jointly, of the respective numbers of shares of Common Stock, par value $0.001 per share, of the Company ("Common Stock") set forth in Schedules A and B hereto and (ii) the grant by the Selling Shareholders to the Underwriters, acting severally and not jointly, of the option described in Section II(B) hereof to purchase all or any part of
[1,500,000] additional shares of Common Stock to cover overallotments, if any. The aforesaid [10,000,000] shares of Common Stock (the "Initial Securities") to be purchased by the Underwriters and all or any part of the [1,500,000] shares of Common Stock subject to the option described in Section II(B) hereof (the "Option Securities") are hereinafter called, collectively, the "Securities."

The Company and the Selling Shareholders understand that the Underwriters propose to make a public offering of the Securities as soon as the Representative deems advisable after this Agreement has been executed and delivered.

The Company, the Selling Shareholders and the Underwriters agree that up to 5% of the Securities to be purchased by the Underwriters (the "Reserved Securities") shall be reserved for


sale by the Underwriters to certain eligible employees and persons having business relationships with the Company (the "Invitees"), as part of the distribution of the Securities by the Underwriters, subject to the terms of this Agreement, the applicable rules, regulations and interpretations of the National Association of Securities Dealers, Inc. ("NASD") and all other applicable laws, rules and regulations. To the extent that such Reserved Securities are not orally confirmed for purchase by Invitees by the end of the first business day after the date of this Agreement, such Reserved Securities may be offered to the public as part of the public offering contemplated hereby.

The Company has filed with the Securities and Exchange Commission (the "Commission") a registration statement on Form S-1 (No. 333-137660), including the related preliminary prospectus or prospectuses, covering the registration of the Securities under the Securities Act of 1933, as amended (the "1933 Act"). Promptly after execution and delivery of this Agreement, the Company will prepare and file a prospectus in accordance with the provisions of Rule 430A ("Rule 430A") of the rules and regulations of the Commission under the 1933 Act (the "1933 Act Regulations") and paragraph (b) of Rule 424 ("Rule 424(b)") of the 1933 Act Regulations. The information included in such prospectus that was omitted from such registration statement at the time it became effective but that is deemed to be part of such registration statement at the time it became effective pursuant to paragraph (b) of Rule 430A is referred to as "Rule 430A Information." Each prospectus used before such registration statement became effective, and any prospectus that omitted the Rule 430A Information, that was used after such effectiveness and prior to the execution and delivery of this Agreement, is herein called a "preliminary prospectus." Such registration statement, including the amendments thereto, the exhibits and any schedules thereto, at the time it became effective, and including the Rule 430A Information, is herein called the "Registration Statement." Any registration statement filed pursuant to Rule 462(b) of the 1933 Act Regulations is herein referred to as the "Rule 462(b) Registration Statement," and after such filing the term "Registration Statement" shall include the Rule 462(b) Registration Statement. The final prospectus in the form first furnished to the Underwriters for use in connection with the offering of the Securities is herein called the "Prospectus." For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus, the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system ("EDGAR").

I. Representations and Warranties.

A. Representations and Warranties by the Company. The Company represents and warrants to each Underwriter as of the date hereof, as of the Applicable Time referred to in Section I(A)(1) hereof, as of the Closing Time referred to in Section II(C) hereof, and as of each Date of Delivery (if any) referred to in Section II(B) hereof, and agrees with each Underwriter, as follows:

1. Compliance with Registration Requirements. Each of the Registration Statement, any Rule 462(b) Registration Statement and any post-effective amendment thereto has become effective under the 1933 Act and no stop order suspending the effectiveness of the Registration Statement, any Rule 462(b) Registration Statement or any post-effective amendment thereto has been issued under the

2

1933 Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company, are threatened by the Commission, and any request on the part of the Commission for additional information has been complied with.

At the respective times the Registration Statement, any Rule 462(b) Registration Statement and any post-effective amendments thereto became effective and at the Closing Time (and, if any Option Securities are purchased, at the Date of Delivery), the Registration Statement, the Rule 462(b) Registration Statement and any amendments and supplements thereto complied and will comply in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations and did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and the Prospectus, any preliminary prospectus and any supplement thereto or prospectus wrapper prepared in connection therewith, at their respective times of issuance and at the Closing Time, complied and will comply in all material respects with any applicable laws or regulations of foreign jurisdictions in which the Prospectus and such preliminary prospectus, as amended or supplemented, if applicable, are distributed in connection with the offer and sale of Reserved Securities. Neither the Prospectus nor any amendments or supplements thereto (including any prospectus wrapper), at the time the Prospectus or any such amendment or supplement was issued and at the Closing Time (and, if any Option Securities are purchased, at the Date of Delivery), included or will include an untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

As of the Applicable Time (as defined below), neither (x) the Issuer General Use Free Writing Prospectuses (as defined below) issued at or prior to the Applicable Time and the Statutory Prospectus (as defined below) as of the Applicable Time and the information included on Schedule C hereto, all considered together (collectively, the "General Disclosure Package"), nor (y) any individual Issuer Limited Use Free Writing Prospectus, when considered together with the General Disclosure Package, included any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

As used in this subsection and elsewhere in this Agreement:

"Applicable Time" means (Eastern time) on [ ] or such other time as agreed by the Company and Merrill Lynch.

"Statutory Prospectus" as of any time means the prospectus relating to the Securities that is included in the Registration Statement immediately prior to the Applicable Time.

"Issuer Free Writing Prospectus" means any "issuer free writing prospectus," as defined in Rule 433 of the 1933 Act Regulations ("Rule 433"), relating to the Securities that (i) is required to be filed with the Commission by the Company, (ii) is a "road show that is a written communication" within the meaning of Rule 433(d)(8)(i) whether or not required to be filed with the Commission or (iii) is exempt from filing pursuant to Rule 433(d)(5)(i) because it contains a description of the Securities or of the offering that does not reflect the final terms, in each case in

3

the form filed or required to be filed with the Commission or, if not required to be filed, in the form retained in the Company's records pursuant to Rule 433(g).

"Issuer General Use Free Writing Prospectus" means any Issuer Free Writing Prospectus that is intended for general distribution to prospective investors (other than a Bona Fide Electronic Road Show (as defined below)), as evidenced by its being specified in Schedule E hereto.

"Issuer Limited Use Free Writing Prospectus" means any Issuer Free Writing Prospectus that is not an Issuer General Use Free Writing Prospectus.

The Company has made available a "bona fide electronic road show," as defined in Rule 433, in compliance with Rule 433(d)(8)(ii) (the "Bona Fide Electronic Road Show") such that no filing of any "road show" (as defined in Rule 433(h)) is required in connection with the offering of the Securities.

Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Securities or until any earlier date that the issuer notified or notifies Merrill Lynch as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement or the Prospectus, and any preliminary or other prospectus deemed to be a part thereof that has not been superseded or modified.

The representations and warranties in this subsection shall not apply to statements in or omissions from the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through Merrill Lynch expressly for use therein.

Each preliminary prospectus (including the prospectus filed as part of the Registration Statement as originally filed or as part of any amendment thereto) complied when so filed in all material respects with the 1933 Act Regulations and each preliminary prospectus and the Prospectus delivered to the Underwriters for use in connection with this offering was identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

At the time of filing the Registration Statement, any 462(b) Registration Statement and any post-effective amendments thereto, at the earliest time thereafter that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) of the 1933 Act Regulations) of the Securities and at the date hereof, the Company was not and is not an "ineligible issuer," as defined in Rule 405 of the 1933 Act Regulations.

As used herein, a "Repayment Event" means any event or condition which gives the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder's behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company or any subsidiary.

11. Absence of Labor Dispute. No labor dispute with the employees of the Company or any subsidiary exists or, to the knowledge of the Company, is imminent, and the Company is not aware of any existing or imminent labor disturbance by the employees of any of its or any subsidiary's principal suppliers, manufacturers, customers or contractors, which, with respect to any such dispute or disturbance, would result in a Material Adverse Effect.

12. Absence of Proceedings. There is no action, suit, proceeding, inquiry or investigation before or brought by any court or governmental agency or body, domestic or foreign, now pending, or, to the knowledge of the Company,

7

threatened, against or affecting the Company or any subsidiary, which is required to be disclosed in the Registration Statement (other than as disclosed therein), or would reasonably be likely to result in a Material Adverse Effect, or which would reasonably be likely to materially and adversely affect the material properties or assets thereof or the consummation of the transactions contemplated in this Agreement or the performance by the Company of its obligations hereunder.

13. Accuracy of Exhibits. There are no contracts or documents which are required to be described in the Registration Statement or, the Prospectus or to be filed as exhibits thereto which have not been so described and filed as required.

15. Absence of Further Requirements. No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental authority or agency is necessary or required for the performance by the Company of its obligations hereunder, in connection with the offering, issuance or sale of the Securities hereunder or the consummation of the transactions contemplated by this Agreement, except (i) filing with the Secretary of State of Delaware an Amended and Restated Certificate of Incorporation, which will be made on or prior to the Applicable Time, (ii) such as have been already obtained or as may be required under the 1933 Act or the 1933 Act Regulations or state securities laws and (iii) such as have been obtained under the laws and regulations of jurisdictions outside the United States in which the Reserved Securities are offered.

17. Possession of Licenses and Permits. The Company and its subsidiaries possess such permits, licenses, approvals, consents and other authorizations (collectively,

8

"Governmental Licenses") issued by the appropriate federal, state, local or foreign regulatory agencies or bodies necessary to conduct the business now operated by them, except where the failure so to possess would not, singly or in the aggregate, result in a Material Adverse Effect; the Company and its subsidiaries are in compliance with the terms and conditions of all such Governmental Licenses, except where the failure so to comply would not, singly or in the aggregate, result in a Material Adverse Effect; all of the Governmental Licenses are valid and in full force and effect, except when the invalidity of such Governmental Licenses or the failure of such Governmental Licenses to be in full force and effect would not, singly or in the aggregate, result in a Material Adverse Effect; and neither the Company nor any of its subsidiaries has received any notice of proceedings relating to the revocation or modification of any such Governmental Licenses which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would result in a Material Adverse Effect.

18. Title to Property. The Company and its subsidiaries have good and marketable title to all real property owned by the Company and its subsidiaries and good title to all other properties owned by them, in each case, free and clear of all mortgages, pledges, liens, security interests, claims, restrictions or encumbrances of any kind except such as (i) are described in the Prospectus or (ii) do not, singly or in the aggregate, materially affect the value of such property and do not interfere with the use made and proposed to be made of such property by the Company or any of its subsidiaries; and all of the leases and subleases material to the business of the Company and its subsidiaries, considered as one enterprise, and under which the Company or any of its subsidiaries holds properties described in the Prospectus, are in full force and effect, and neither the Company nor any subsidiary has any notice of any material claim of any sort that has been asserted by anyone adverse to the rights of the Company or any subsidiary under any of the leases or subleases mentioned above, or affecting or questioning the rights of the Company or such subsidiary to the continued possession of the leased or subleased premises under any such lease or sublease.

19. Investment Company Act. The Company is not required, and upon the issuance and sale of the Securities as herein contemplated and the application of the net proceeds therefrom as described in the Prospectus will not be required, to register as an "investment company" under the Investment Company Act of 1940, as amended (the "1940 Act").

20. Environmental Laws. Except as described in the Registration Statement and except as would not, singly or in the aggregate, result in a Material Adverse Effect, (i) neither the Company nor any of its subsidiaries is in violation of any applicable federal, state, local or foreign statute, law, rule, regulation, ordinance, code or rule of common law or any judicial or administrative interpretation thereof, including any judicial or administrative order, consent, decree or judgment, relating to pollution or protection of the environment (including, without limitation, ambient air, surface water, groundwater, land surface or subsurface strata) or wildlife, including, without limitation, laws and regulations

9

relating to the release into the environment or threatened release into the environment of chemicals, pollutants, contaminants, wastes, toxic substances, hazardous substances, petroleum or petroleum products or asbestos-containing materials (collectively, "Hazardous Materials") or to the environmental aspects of the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials (collectively, "Environmental Laws"), (ii) the Company and its subsidiaries have all permits, authorizations and approvals required for their respective operations under any applicable Environmental Laws and are each in compliance with their requirements, (iii) there are no pending or to the knowledge of the Company threatened administrative, regulatory or judicial actions, suits, demands, demand letters, claims, liens, notices of noncompliance or violation or proceedings or, to the knowledge of the Company, any investigation relating to any Environmental Law against the Company or any of its subsidiaries and (iv) to the knowledge of the Company there are no known events or circumstances existing as of the date hereof that would reasonably be expected to form the basis of an order for clean-up or remediation, or an action, suit or proceeding by any private party or governmental body or agency, against or affecting the Company or any of its subsidiaries relating to Hazardous Materials or any Environmental Laws.

21. Registration Rights.

A. Initial Securities. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company and each Selling Shareholder, severally and not jointly, agree to sell to each Underwriter, severally and not jointly, and each Underwriter, severally and not jointly, agrees to purchase from the Company and each Selling Shareholder, at the price per share set forth in Schedule C, that proportion of the number of Initial Securities set forth in Schedule B opposite the name of the Company or such Selling Shareholder, as the case may be, which the number of Initial Securities set forth in Schedule A opposite the name of such Underwriter, plus any additional number of Initial Securities which such Underwriter may become obligated to purchase pursuant to the provisions of
Section X hereof, bears to the total number of Initial Securities, subject, in each case, to such adjustments among the Underwriters as the Representative in its sole discretion shall make to eliminate any sales or purchases of fractional securities.

B. Option Securities. In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Selling Shareholders, hereby grant an option to the Underwriters, severally and not jointly, to purchase up to an additional [1,500,000] shares of Common Stock, as set forth in Schedule B, at the price per share set forth in Schedule C, less an amount per share equal to any dividends or distributions declared by the Company and payable on the Initial Securities but not payable on the Option Securities. The option hereby granted will expire 30 days after the date hereof and may be exercised in whole or in part from time to time only for the purpose of covering overallotments

15

which may be made in connection with the offering and distribution of the Initial Securities upon notice by the Representative to the Selling Shareholders setting forth the number of Option Securities as to which the several Underwriters are then exercising the option and the time and date of payment and delivery for such Option Securities. Any such time and date of delivery (a "Date of Delivery") shall be determined by the Representative, but shall not be later than seven full business days after the exercise of said option, nor in any event prior to the Closing Time, as hereinafter defined. If the option is exercised as to all or any portion of the Option Securities, each of the Underwriters, acting severally and not jointly, will purchase that proportion of the total number of Option Securities then being purchased which the number of Initial Securities set forth in Schedule A opposite the name of such Underwriter bears to the total number of Initial Securities, subject in each case to such adjustments as the Representative in its discretion shall make to eliminate any sales or purchases of fractional shares.

C. Payment. Payment of the purchase price for, and delivery of certificates for, the Initial Securities shall be made at the offices of Fried, Frank, Harris, Shriver and Jacobson LLP in the City of New York, or at such other place as shall be agreed upon by the Representative and the Company and the Selling Shareholders, at 9:00 A.M. (Eastern time) on the third (fourth, if the pricing occurs after 4:30 P.M. (Eastern time) on any given day) business day after the date hereof (unless postponed in accordance with the provisions of
Section X), or such other time not later than ten business days after such date as shall be agreed upon by the Representative and the Company and the Selling Shareholders (such time and date of payment and delivery being herein called "Closing Time").

In addition, in the event that any or all of the Option Securities are purchased by the Underwriters, payment of the purchase price for, and delivery of certificates for, such Option Securities shall be made at the above-mentioned offices, or at such other place as shall be agreed upon by the Representative and the Company and the Selling Shareholders, on each Date of Delivery as specified in the notice from the Representative to the Company and the Selling Shareholders.

Payment shall be made to the Company and the Selling Shareholders by wire transfer of immediately available funds to a bank account designated by the Company and the Custodian pursuant to each Selling Shareholder's Power of Attorney and Custody Agreement, as the case may be, against delivery to the Representative for the respective accounts of the Underwriters of certificates for the Securities to be purchased by them. It is understood that each Underwriter has authorized the Representative, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Initial Securities and the Option Securities, if any, which it has agreed to purchase. Merrill Lynch, individually and not as representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Initial Securities or the Option Securities, if any, to be purchased by any Underwriter whose funds have not been received by the Closing Time or the relevant Date of Delivery, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder.

D. Denominations; Registration. Certificates for the Initial Securities and the Option Securities, if any, shall be in such denominations and registered in such names as the Representative may request in writing at least two full business days before the Closing Time or the relevant Date of Delivery, as the case may be.

16

the Option Securities, if any, will be made available for examination and packaging by the Representative in The City of New York not later than 10:00
A.M. (Eastern time) on the business day prior to the Closing Time or the relevant Date of Delivery, as the case may be.

III. Covenants of the Company and the Selling Shareholders. The Company covenants with each Underwriter as follows:

A. Compliance with Securities Regulations and Commission Requests. The Company, subject to Section III(B), will comply with the requirements of Rule 430A, and will notify the Representative immediately, (1) when any post-effective amendment to the Registration Statement shall become effective, or any supplement to the Prospectus or any amended Prospectus shall have been filed, (2) of the receipt of any comments from the Commission, (3) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or for additional information, (4) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of any preliminary prospectus, or of the suspension of the qualification of the Securities for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes or of any examination pursuant to Section 8(e) of the 1933 Act concerning the Registration Statement and (5) if the Company becomes the subject of a proceeding under Section 8A of the 1933 Act in connection with the offering of the Securities. The Company will effect the filings required under Rule 424(b), in the manner and within the time period required by Rule 424(b) (without reliance on Rule 424(b)(8)), and will take such steps as it deems necessary to ascertain promptly whether the form of prospectus transmitted for filing under Rule 424(b) was received for filing by the Commission and, in the event that it was not, it will promptly file such prospectus. The Company will make every reasonable effort to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof as soon as practicable.

B. Filing of Amendments and Exchange Act Documents. The Company will give the Representative notice of its intention to file or prepare any amendment to the Registration Statement (including any filing under Rule 462(b)) or any amendment, supplement or revision to either the prospectus included in the Registration Statement at the time it became effective or to the Prospectus, and will furnish the Representative with copies of any such documents a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Representative or counsel for the Underwriters reasonably shall object (other than a document which the Company believes it is required by law to file). The Company will give the Representative notice of its intention to make any such filing pursuant to the 1934 Act or the 1934 Act Regulations from the Applicable Time to the Closing

17

Time and will furnish the Representative with copies of any such documents a reasonable amount of time prior to such proposed filing, as the case may be, and will not file or use any such document to which the Representative or counsel for the Underwriters shall reasonably object (other than a document which the Company believes it is required to file by law).

C. Delivery of Registration Statements. The Company has furnished or will deliver upon request to the Representative and counsel for the Underwriters, without charge, conformed copies of the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith) and copies of all signed consents and certificates of experts.

D. Delivery of Prospectuses. The Company has delivered to each Underwriter, without charge, as many copies of each preliminary prospectus as such Underwriter reasonably requested, and the Company hereby consents to the use of such copies for purposes permitted by the 1933 Act. The Company will furnish to each Underwriter, without charge, during the period when the Prospectus is required to be delivered under the 1933 Act, such number of copies of the Prospectus (as amended or supplemented) as such Underwriter may reasonably request. The Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

E. Continued Compliance with Securities Laws. The Company will comply with the 1933 Act and the 1933 Act Regulations so as to permit the completion of the distribution of the Securities as contemplated in this Agreement and in the Prospectus. If at any time when a prospectus is required by the 1933 Act to be delivered in connection with sales of the Securities, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or for the Company, to amend the Registration Statement or amend or supplement the Prospectus in order that the Prospectus will not include any untrue statements of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement the Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company will promptly prepare and file with the Commission, subject to Section III(B), such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements, and the Company will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request. If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement relating to the Securities or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances, prevailing at that subsequent time, not misleading, the Company will promptly notify Merrill Lynch and will promptly amend or supplement, at its own expense, such

18

Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

F. Blue Sky Qualifications. The Company will use its best efforts, in cooperation with the Underwriters, to qualify the Securities for offering and sale under the applicable securities laws of such states and other domestic jurisdictions as the Representative may designate and to maintain such qualifications in effect for a period of not less than one year from the later of the effective date of the Registration Statement and any Rule 462(b) Registration Statement; provided, however, that the Company shall not be obligated to file any general consent or otherwise subject itself to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

G. Rule 158. The Company will timely file such reports pursuant to the Securities Exchange Act of 1934 (the "1934 Act") as are necessary in order to make generally available to its securityholders as soon as practicable an earnings statement for the purposes of, and to provide to the Underwriters the benefits contemplated by, the last paragraph of Section 11(a) of the 1933 Act.

During a period of 180 days from the date of the Prospectus, the Company will not, without the prior written consent of Merrill Lynch, (1) directly or indirectly, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of any share of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or file any registration statement under the 1933 Act with respect to any of the foregoing or (2) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Common Stock, whether any such swap or transaction described in clause (1) or
(2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (A) the Securities to be sold hereunder, (B) any shares of Common Stock issued by the Company upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof (including any preferred stock) and referred to in the Prospectus, (C) any shares of Common Stock issued or options to purchase Common Stock granted pursuant to existing employee benefit plans of the Company referred to in the Prospectus or (D) any shares of Common Stock issued pursuant to any non-employee director stock plan or dividend reinvestment plan. Notwithstanding the foregoing, if (i) during the last 17 days of the 180-day restricted period the Company issues an earnings release or material news or a material event relating to the Company occurs or (ii) prior to the expiration of the 180-day restricted period, the Company announces that it will release earnings results or becomes aware that material news or a material event will occur during the 16-day period beginning on the last day of the 180-day restricted period, the restrictions imposed in this

19

paragraph shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

K. Reporting Requirements. The Company, during the period when the Prospectus is required to be delivered under the 1933 Act, will file all documents required to be filed with the Commission pursuant to the 1934 Act within the time periods required by the 1934 Act and the rules and regulations of the Commission thereunder.

L. Compliance with NASD Rules. The Company hereby agrees that it will ensure that the Reserved Securities will be restricted as required by the NASD or the NASD rules from sale, transfer, assignment, pledge or hypothecation for a period of three months following the date of this Agreement. The Underwriters will notify the Company as to which persons will need to be so restricted. At the request of the Underwriters, the Company will direct the transfer agent to place a stop transfer restriction upon such Reserved Securities for such period of time. Should the Company release, or seek to release, from such restrictions any of the Reserved Securities, the Company agrees to reimburse the Underwriters for any reasonable expenses (including, without limitation, legal expenses) they incur in connection with such release.

M. Issuer Free Writing Prospectuses. Each of the Company and each Selling Shareholder represents and agrees that, unless it obtains the prior consent of the Representative, and each Underwriter represents and agrees that, unless it obtains the prior consent of the Company and the Representative, it has not made and will not make any offer relating to the Securities that would constitute an "issuer free writing prospectus," as defined in Rule 433, or that would otherwise constitute a "free writing prospectus," as defined in Rule 405, required to be filed with the Commission or, in the case of each Selling Shareholder, whether or not required to be filed with the Commission. Any such free writing prospectus consented to by the Company and the Representative is hereinafter referred to as a "Permitted Free Writing Prospectus." Each of the Company and each Selling Shareholder represents that it has treated or agrees that it will treat each Permitted Free Writing Prospectus as an "issuer free writing prospectus," as defined in Rule 433, and has complied and will comply with the requirements of Rule 433 applicable to any Permitted Free Writing Prospectus, including timely filing with the Commission where required, legending and record keeping.

Section III(M) shall restrict the Company from making any filings required under the 1934 Act or 1934 Act Regulations.

VI. Indemnification.

A. Indemnification of Underwriters. (1) The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, as such term is defined in Rule 501(b) under the 1933 Act (each, an "Affiliate"), its selling agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

1. against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including the Rule 430A Information or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

2. against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to
Section VI (E) below) any such settlement is effected with the written consent of the Company.

3. against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by Merrill Lynch), reasonably

25

incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (1) or
(2) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through Merrill Lynch expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430A Information, or any preliminary prospectus, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto).

(2) In addition to and without limitation of the Company's obligation to indemnify Robert W. Baird as an Underwriter, the Company agrees to indemnify and hold harmless the Independent Underwriter, its Affiliates and Selling Agents and each person, if any, who controls the Independent Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, from and against any and all loss, liability, claim, damage and expense whatsoever, as incurred, incurred as a result of the Independent Underwriter's participation as a "qualified independent underwriter" within the meaning of Rule 2720 of the Conduct Rules of the NASD in connection with the offering of the Securities.

B. Indemnification by Selling Shareholder. Each Selling Shareholder, severally and not jointly, agrees to indemnify and hold harmless each Underwriter, its Affiliates and selling agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act to the extent and in the manner set forth in clauses (A)(1), (2) and (3) above in connection with the offering of the Securities by the Selling Shareholder; provided, however, that the aggregate indemnification liability of each Selling Shareholder shall not exceed the net proceeds received by such person from the sale of the Securities sold by such person in the public offering pursuant to this Agreement; and provided, further that each Selling Shareholder shall be liable only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission has been made in the Registration Statement, any preliminary prospectus, the Prospectus or such amendment or supplement in reliance upon and in conformity with information furnished by such Selling Shareholder expressly for use in such document, it being understood and agreed that the only such information furnished by the Selling Shareholders consists of the names and addresses of the Selling Shareholders.

C. Indemnification of Company, Directors and Officers and Selling Shareholders. Each Underwriter severally agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and each Selling Shareholder and each person, if any, who controls any Selling Shareholder within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and

26

all loss, liability, claim, damage and expense described in the indemnity contained in subsection (A) (1) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including the Rule 430A Information or any preliminary prospectus, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by such Underwriter through Merrill Lynch expressly for use therein.

D. Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section VI(A) (1) above, counsel to the indemnified parties shall be selected by Merrill Lynch, and, in the case of parties indemnified pursuant to Section VI(C) above, counsel to the indemnified parties shall be selected by the Company and the Selling Shareholders. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. Any such separate counsel for the Independent Underwriter and such control persons of the Independent Underwriter shall be designated in writing by the Independent Underwriter. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section VI or Section VII hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

E. Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by
Section VI(A) (1) or settlement of any claim in connection with any violation referred to in Section VI(F) effected without its written consent if (1) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (2) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (3) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

27

F. Indemnification for Reserved Securities. In connection with the offer and sale of the Reserved Securities, the Company agrees to indemnify and hold harmless the Underwriters, their Affiliates and selling agents and each person, if any, who controls any Underwriter within the meaning of either
Section 15 of the 1933 Act or Section 20 of the 1934 Act, from and against any and all loss, liability, claim, damage and expense (including, without limitation, any legal or other expenses reasonably incurred in connection with defending, investigating or settling any such action or claim), as incurred, (1) arising out of the violation of any applicable laws or regulations of foreign jurisdictions where Reserved Securities have been offered; (2) arising out of any untrue statement or alleged untrue statement of a material fact contained in any prospectus wrapper or other material prepared by or with the consent of the Company for distribution to Invitees in connection with the offering of the Reserved Securities or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; (3) caused by the failure of any Invitee to pay for and accept delivery of Reserved Securities which have been orally confirmed for purchase by any Invitee by the end of the first business day after the date of the Agreement; or (4) related to, or arising out of or in connection with, the offering of the Reserved Securities.

G. Other Agreements with Respect to Indemnification. The provisions of this Section shall not affect any agreement among the Company and the Selling Shareholders with respect to indemnification.

VII. Contribution. If the indemnification provided for in Section VI hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Shareholders on the one hand and the Underwriters on the other hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Selling Shareholders on the one hand and of the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company and the Selling Shareholders on the one hand and the Underwriters on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company and the Selling Shareholders and the total underwriting discount received by the Underwriters, in each case as set forth on the cover of the Prospectus bear to the aggregate initial public offering price of the Securities as set forth on the cover of the Prospectus.

The relative fault of the Company and the Selling Shareholders on the one hand and the Underwriters on the other hand shall be determined by reference to whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact

28

relates to information supplied by the Company or the Selling Shareholders, it being understood and agreed that the only such information supplied by the Selling Shareholders consists of the names and addresses of the Selling Shareholders, or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company, the Selling Shareholders and the Underwriters agree that Robert W. Baird will not receive any additional benefits hereunder for serving as the Independent Underwriter in connection with the offering and sale of the Securities.

The Company, the Selling Shareholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section VII were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section
VII. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section VII shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section VII, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section VII, no Selling Shareholder shall be required to contribute any amount in excess of the net proceeds received by such Selling Shareholder from the sale of the Securities in the public offering exceeds the amount of any damages which such Selling Shareholder has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section VII, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and each Underwriter's Affiliates and selling agents shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company or any Selling Shareholder within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company or such Selling Shareholder, as the case may be. The Underwriters' respective obligations to contribute pursuant to this Section VII are several in proportion to the number of Initial Securities set forth opposite their respective names in Schedule A hereto and not joint.

29

The provisions of this Section shall not affect any agreement among the Company and the Selling Shareholders with respect to contribution.

VIII. Representations, Warranties and Agreements to Survive. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries or the Selling Shareholders submitted pursuant hereto, shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of any Underwriter or its Affiliates or selling agents, any person controlling any Underwriter, its officers or directors, any person controlling the Company or any person controlling any Selling Shareholder and (ii) delivery of and payment for the Securities.

IX. Termination of Agreement.

A. Termination; General. The Representative may terminate this Agreement, by written notice to the Company and the Selling Shareholders, at any time at or prior to Closing Time (1) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus or General Disclosure Package, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (2) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representative, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (3) if trading in any securities of the Company has been suspended or materially limited by the Commission or the Nasdaq Global Market, or if trading generally on the American Stock Exchange or the New York Stock Exchange or in the Nasdaq Global Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the NASD or any other governmental authority, or (4) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, or
(5) if a banking moratorium has been declared by either Federal, Delaware or New York authorities.

B. Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections I, V, VI and VIII shall survive such termination and remain in full force and effect.

X. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at Closing Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Agreement (the "Defaulted Securities"), the Representative shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set

30

forth; if, however, the Representative shall not have completed such arrangements within such 24-hour period, then:

1. if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

2. if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date, this Agreement or, with respect to any Date of Delivery which occurs after the Closing Time, the obligation of the Underwriters to purchase and of the Company to sell the Option Securities to be purchased and sold on such Date of Delivery shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section X shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the Underwriters to purchase and the Company or any Selling Shareholder to sell the relevant Option Securities, as the case may be, either the (i) Representative or
(ii) the Company and any Selling Shareholder shall have the right to postpone the Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used herein, the term "Underwriter" includes any person substituted for an Underwriter under this Section X.

XI. Default by one or more of the Selling Shareholders or the Company.

A. If a Selling Shareholder shall fail at Closing Time or at a Date of Delivery to sell and deliver the number of Securities which such Selling Shareholder are obligated to sell hereunder, and the remaining Selling Shareholders do not exercise the right hereby granted to increase, pro-rata or otherwise, the number of Securities to be sold by them hereunder to the total number to be sold by all Selling Shareholders as set forth on Schedule B hereto, then the Underwriters may, at option of the Representative, by notice from the Representative to the Company and the non-defaulting Selling Shareholders, either (i) terminate this Agreement without any liability on the fault of any non-defaulting party except that the provisions of Sections I, IV, VI, VII and VIII shall remain in full force and effect or (ii) elect to purchase the Securities which the non-defaulting Selling Shareholders have agreed to sell hereunder. No action taken pursuant to this Section XI shall relieve any Selling Shareholder so defaulting from liability, if any, in respect of such default.

In the event of a default by any Selling Shareholder as referred to in this Section XI, each of the Representative and the Company shall have the right to postpone Closing Time or Date of

31

Delivery for a period not exceeding seven days in order to effect any required change in the Registration Statement or Prospectus or in any other documents or arrangements.

B. If the Company shall fail at Closing Time or at the Date of Delivery to sell the number of Securities that it is obligated to sell hereunder, then this Agreement shall terminate without any liability on the part of any nondefaulting party; provided, however, that the provisions of Sections I, IV, VI, VII and VIII shall remain in full force and effect. No action taken pursuant to this Section shall relieve the Company from liability, if any, in respect of such default.

XII. Tax Disclosure. Notwithstanding any other provision of this Agreement, immediately upon commencement of discussions with respect to the transactions contemplated hereby, the Company (and each employee, representative or other agent of the Company) may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the transactions contemplated by this Agreement and all materials of any kind (including opinions or other tax analyses) that are provided to the Company relating to such tax treatment and tax structure. For purposes of the foregoing, the term "tax treatment" is the purported or claimed federal income tax treatment of the transactions contemplated hereby, and the term "tax structure" includes any fact that may be relevant to understanding the purported or claimed federal income tax treatment of the transactions contemplated hereby.

XIII. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.

Adas.

XIV. No Advisory or Fiduciary Relationship.

Re: Proposed Public Offering by Altra Holdings, Inc.

Dear Sirs:

The undersigned, a stockholder, officer, director and/or employee of Altra Holdings, Inc., a Delaware corporation (the "Company"), understands that Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch"), Jefferies & Company, Wachovia Securities and Robert W. Baird & Co., propose to enter into a Purchase Agreement (the "Purchase Agreement") with the Company and the Selling Shareholders providing for the public offering of shares (the "Public Offering") of the Company's common stock, par value $0.001 per share (the "Common Stock"). In recognition of the benefit that such an offering will confer upon the undersigned as a stockholder, officer, director and/or employee of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with each underwriter to be named in the Purchase Agreement that, during a period of 180 days from the date of the Purchase Agreement, the undersigned will not, without the prior written consent of Merrill Lynch, directly or indirectly, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or transfer any shares of the Common Stock or any securities convertible into or exchangeable or exercisable for Common Stock, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition, or file, or cause to be filed, any registration statement under the Securities Act of 1933, as amended, with respect to any of the foregoing (collectively, the "Lock-Up Securities") or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Lock-Up Securities, whether any such swap or transaction is to be settled by delivery of Common Stock or other securities, in cash or

C-1

otherwise; provided, however, that the foregoing restrictions will not apply to transfers of the Lock-Up Securities (A) as a bona fide gift, provided that each donee thereof agrees to be bound in writing by the restrictions set forth herein, or (B) to any trust or other entity formed for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust or authorized representative of such other entity, as applicable, agrees to be bound in writing by the restrictions set forth herein.

Notwithstanding the foregoing, the undersigned may sell shares of Common Stock purchased by the undersigned on the open market following the Public Offering if and only if (i) such sales are not required to be reported in any public report or filing with the Securities Exchange Commission, or otherwise and (ii) the undersigned does not otherwise voluntarily effect any public filing or report regarding such sales.

Notwithstanding the foregoing, if:

(1) during the last 17 days of the 180-day lock-up period, the Company issues an earnings release or material news or a material event relating to the Company occurs; or

(2) prior to the expiration of the 180-day lock-up period, the Company announces that it will release earnings results or becomes aware that material news or a material event will occur during the 16-day period beginning on the last day of the 180-day lock-up period;

the restrictions imposed by this lock-up agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event, as applicable, unless Merrill Lynch waives, in writing, such extension.

The undersigned hereby acknowledges and agrees that written notice of any extension of the 180-day lock-up period pursuant to the previous paragraph will be delivered by Merrill Lynch to the Company (in accordance with
Section XII of the Purchase Agreement) and that any such notice properly delivered will be deemed to have been given to, and received by, the undersigned. The undersigned further agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this lock-up agreement during the period from the date of this lock-up agreement to and including the 34th day following the expiration of the initial 180-day lock-up period, it will give notice thereof to the Company and will not consummate such transaction or take any such action unless it has received written confirmation from the Company that the 180-day lock-up period (as may have been extended pursuant to the previous paragraph) has expired.

The undersigned also agrees and consents to the entry of stop transfer instructions with the Company's transfer agent and registrar against the transfer of the Lock-Up Securities except in compliance with the foregoing restrictions.

C-2

The obligation of the undersigned shall terminate if the Public Offering shall not have been effected on or before February 15, 2007.

Very truly yours,

The Board of Directors of the Corporation may decrease the number of shares of the Preferred Stock designated for any existing class or series by a resolution subtracting from such class or series authorized and unissued shares of the Preferred Stock designated for such existing class or series, and the shares so subtracted shall become authorized, unissued, and undesignated shares of the Preferred Stock.

C. GENERAL

Subject to the foregoing provisions of this Certificate of Incorporation, the Corporation may issue shares of its Preferred Stock and Common Stock from time to time for such consideration (not less than the par value thereof) as may be fixed by the Board of Directors of the Corporation, which is expressly authorized to fix the same in its absolute and uncontrolled discretion subject to the foregoing conditions. Shares so issued for which the consideration shall have been paid or delivered to the Corporation shall be deemed fully paid stock and shall not be liable to any further call or assessment thereon, and the holders of such shares shall not be liable for any further payments in respect of such shares.

The Corporation shall have authority to create and issue rights and options entitling their holders to purchase shares of the Corporation's capital stock of any class or series or other securities of the Corporation, and such rights and options shall be evidenced by instrument(s) approved by the Board of Directors of the Corporation. The Board of Directors of the Corporation shall be empowered to set the exercise price, duration, times for exercise, and other terms of such options or rights; provided, however, that the consideration to be received for any shares of capital stock subject thereto shall not be less than the par value thereof.

ARTICLE V

STOCKHOLDER ACTION

1. Action without Meeting. Except as otherwise provided herein, any action required or permitted to be taken by the stockholders of the Corporation at any annual or special meeting of stockholders of the Corporation must be effected at a duly called annual or special meeting of stockholders and may not be taken or effected by a written consent of stockholders in lieu thereof.

2. Special Meetings. Except as otherwise required by statute and subject to the rights, if any, of the holders of any series of Preferred Stock, special meetings of the stockholders of the Corporation may be called only by the Board of Directors acting pursuant to a resolution approved by the affirmative vote of a majority of the Directors then in office. Only those matters set forth in the notice of the special meeting may be considered or acted upon at a special meeting of stockholders of the Corporation.

ARTICLE VI

DIRECTORS

1. General. The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors except as otherwise provided herein or required by law.

2. Election of Directors. Election of Directors need not be by written ballot unless the Bylaws of the Corporation (the "Bylaws") shall so provide.

3. Number of Directors; Term of Office. The number of Directors of the Corporation shall be fixed solely by resolution duly adopted from time to time by the Board of Directors. At each annual meeting of stockholders, Directors of the Corporation shall be elected to hold office until the expiration of the term for which they are elected, and until their successors have been duly elected and qualified or until their earlier resignation, death or removal; except that if any such election shall be not so held, such election shall take place at stockholders' meeting called and held in accordance with the DGCL. No decrease in the number of Directors shall shorten the term of any incumbent Director.

Notwithstanding the foregoing, whenever, pursuant to the provisions of Article IV of this Certificate of Incorporation, the holders of any one or more series of Preferred Stock shall have the right, voting separately as a series or together with holders of other such series, to elect Directors at an annual or special meeting of stockholders, the election, term of office, filling of vacancies and other features of such directorships shall be governed by the terms of this Certificate of Incorporation and any certificate of designations applicable thereto.

4. Vacancies. Subject to the rights, if any, of the holders of any series of Preferred Stock to elect Directors and to fill vacancies in the Board of Directors relating thereto, any and all vacancies in the Board of Directors, however occurring, including, without limitation, by reason of an increase in size of the Board of Directors, or the death, resignation, disqualification or removal of a Director, shall be filled solely by the affirmative vote of a majority of the remaining Directors then in office, even if less than a quorum of the Board of Directors. Any

5

Director appointed in accordance with the preceding sentence shall hold office until such Director's successor shall have been duly elected and qualified or until his or her earlier resignation, death or removal. In the event of a vacancy in the Board of Directors, the remaining Directors, except as otherwise provided by law, shall exercise the powers of the full Board of Directors until the vacancy is filled.

5. Removal. Subject to the rights, if any, of any series of Preferred Stock to elect Directors and to remove any Director whom the holders of any such stock have the right to elect, any Director (including persons elected by Directors to fill vacancies in the Board of Directors) may be removed from office, with or without cause, by the affirmative vote of the holders of a majority of the shares then entitled to vote at an election of Directors.

ARTICLE VII

LIMITATION OF LIABILITY

A Director of the Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a Director, except for liability (a) for any breach of the Director's duty of loyalty to the Corporation or its stockholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) under Section 174 of the DGCL or (d) for any transaction from which the Director derived an improper personal benefit. If the DGCL is amended after the effective date of this Certificate of Incorporation to authorize corporate action further eliminating or limiting the personal liability of Directors, then the liability of a Director of the Corporation shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended.

Any repeal or modification of this Article VII, by either (i) the stockholders of the Corporation or (ii) an amendment to the DGCL, shall not adversely affect any right or protection existing at the time of such repeal or modification with respect to any acts or omissions occurring before such repeal or modification of a person serving as a Director at the time of such repeal or modification.

ARTICLE VIII

INDEMNIFICATION

The Corporation shall indemnify any person who was, is, or is threatened to be made a party to a proceeding (as hereinafter defined) by reason of the fact that he or she (i) is or was a director of the Corporation or (ii) while a director of the Corporation, is or was serving at the request of the Corporation as a director (or similar role) of another foreign or domestic corporation, partnership, joint venture, sole proprietorship, trust, employee benefit plan, or other enterprise to the fullest extent permitted under the DGCL. Such right shall be a contract right and as such shall run to the benefit of any director who is elected and accepts the position of director of the Corporation or elects to continue to serve as a director of the Corporation while this Article VIII is in effect. Any repeal or amendment of this Article VIII shall be prospective only and shall not limit the rights of any such director or the obligations of the Corporation with respect to any claim arising from or related to the services of such director in any of the foregoing capacities prior to any such repeal or amendment to this Article VIII. Such right shall

6

include the right to be paid by the Corporation expenses incurred in defending any such proceeding in advance of its final disposition to the maximum extent permitted under the DGCL. If a claim for indemnification or advancement of expenses hereunder is not paid in full by the Corporation within sixty (60) days after a written claim has been received by the Corporation, the claimant may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim, and if successful in whole or in part, the claimant shall also be entitled to be paid the expenses of prosecuting such claim. It shall be a defense to any such action that such indemnification or advancement of costs of defense are not permitted under the DGCL, but the burden of proving such defense shall be on the Corporation. Neither the failure of the Corporation (including its Board of Directors or any committee thereof, independent legal counsel, or stockholders) to have made its determination prior to the commencement of such action that indemnification of, or advancement of costs of defense to, the claimant is permissible in the circumstances nor an actual determination by the Corporation (including its Board of Directors or any committee thereof, independent legal counsel, or stockholders) that such indemnification or advancement is not permissible shall be a defense to the action or create a presumption that such indemnification or advancement is not permissible. In the event of the death of any person having a right of indemnification under the foregoing provisions, such right shall inure to the benefit of his or her heirs, executors, administrators, and personal representatives. The rights conferred above shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, bylaw, resolution of stockholders or directors, agreement, or otherwise.

As used herein, the term "proceeding" means any threatened, pending, or completed action, suit, or proceeding, whether civil, criminal, administrative, arbitrative, or investigative, any appeal in such an action, suit, or proceeding, and any inquiry or investigation that could lead to such an action, suit, or proceeding.

AMENDED AND RESTATED

BYLAWS

OF

ALTRA HOLDINGS, INC.
A DELAWARE CORPORATION

(THE "CORPORATION")

ARTICLE I

Stockholders

SECTION 1. Annual Meeting. The annual meeting of stockholders (any such meeting being referred to in these Bylaws as an "Annual Meeting") shall be held at the hour, date and place within or outside of the United States which is fixed by the Board of Directors, which time, date and place may subsequently be changed at any time by vote of the Board of Directors. If no Annual Meeting has been held for a period of thirteen months after the Corporation's last Annual Meeting, a special meeting in lieu thereof may be held, and such special meeting shall have, for the purposes of these Bylaws or otherwise, all the force and effect of an Annual Meeting. Any and all references hereafter in these Bylaws to an Annual Meeting or Annual Meetings also shall be deemed to refer to any special meeting(s) in lieu thereof. The stockholders of the Corporation may not take any action by written consent in lieu of a meeting, and must take any actions at a duly called annual or special meeting of stockholders and the power of stockholders to consent in writing without a meeting is specifically denied.

SECTION 2. Notice of Stockholder Business and Nominations.

(a) Annual Meetings of Stockholders.

(i) Nominations of persons for election to the Board of Directors of the Corporation and the proposal of business to be considered by the stockholders may be made at an Annual Meeting (a) pursuant to the Corporation's notice of meeting, (b) by or at the direction of the Board of Directors or (c) by any stockholder of the Corporation who was a stockholder of record at the time of giving of notice provided for in this Bylaw, who is entitled to vote at the meeting, who is present (in person or by proxy) at the meeting and who complies with the notice procedures set forth in this Bylaw. In addition to the other requirements set forth in this Bylaw, for any proposal of business to be considered at an Annual Meeting, it must be a proper subject for action by stockholders of the Corporation under Delaware law.

(ii) For nominations or other business to be properly brought before an Annual Meeting by a stockholder pursuant to clause (c) of paragraph
(a)(i) of this Bylaw, the stockholder must have given timely notice thereof in writing to the Secretary of the Corporation. To be timely, a stockholder's notice shall be delivered to the Secretary at the principal executive


offices of the Corporation not later than the close of business on the 90th day nor earlier than the close of business on the 120th day prior to the first anniversary of the preceding year's Annual Meeting; provided, however, that in the event that the date of the Annual Meeting is advanced by more than 30 days before or delayed by more than 60 days after such anniversary date, notice by the stockholder to be timely must be so delivered not later than the close of business on the later of the 90th day prior to such Annual Meeting or the 10th day following the day on which Public Announcement of the date of such meeting is first made. Such stockholder's notice shall set forth: (a) as to each person whom the stockholder proposes to nominate for election or reelection as a director, all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors in an election contest, or is otherwise required, in each case pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended (the "Exchange Act") (including such person's written consent to being named in the proxy statement as a nominee and serving as a director if elected); (b) as to any other business that the stockholder proposes to bring before the meeting, a brief description of the business desired to be brought before the meeting, the reasons for conducting such business at the meeting, any material interest in such business of such stockholder and the beneficial owner, if any, on whose behalf the proposal is made, and the names and addresses of other stockholders known by the stockholder proposing such business to support such proposal, and the class and number of shares of the Corporation's capital stock beneficially owned by such other stockholders; and (c) as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination or proposal is made (1) the name and address of such stockholder, as they appear on the Corporation's books, and of such beneficial owner, (2) the class and number of shares of the Corporation which are owned beneficially and of record by such stockholder and such beneficial owner, (3) a description of all arrangements or understandings between such beneficial owner and each proposed nominee and any other person or persons (including their names) pursuant to which the nomination(s) are to be made, and (4) a representation whether the beneficial owner intends or is part of a group that intends (A) to deliver a proxy statement and/or form of proxy to holders of at least the percentage of the Corporation's outstanding capital stock required to elect the nominee and/or (B) otherwise to solicit proxies from stockholders in support of such nomination.

(iii) Notwithstanding anything in the second sentence of paragraph (a)(ii) of this Section 2 to the contrary, in the event that the number of directors to be elected to the Board of Directors of the Corporation is increased and there is no Public Announcement naming all of the nominees for director or specifying the size of the increased Board of Directors made by the Corporation at least 85 days prior to the first anniversary of the preceding year's Annual Meeting, a stockholder's notice required by this Bylaw shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be delivered to the Secretary at the principal executive offices of the Corporation not later than the close of business on the 10th day following the day on which such Public Announcement is first made by the Corporation.

(b) General.

(i) Only such persons who are nominated in accordance with the provisions of this Bylaw shall be eligible for election and to serve as directors and only such business shall be conducted at an Annual Meeting as shall have been brought before the meeting in accordance

2

with the provisions of this Bylaw. The Board of Directors or a designated committee thereof shall have the power to determine whether a nomination or any business proposed to be brought before the meeting was made in accordance with the provisions of this Bylaw. If neither the Board of Directors nor such designated committee makes a determination as to whether any stockholder proposal or nomination was made in accordance with the provisions of this Bylaw, the presiding officer of the Annual Meeting shall have the power and duty to determine whether the stockholder proposal or nomination was made in accordance with the provisions of this Bylaw. If the Board of Directors or a designated committee thereof or the presiding officer, as applicable, determines that any stockholder proposal or nomination was not made in accordance with the provisions of this Bylaw, such proposal or nomination shall be disregarded and shall not be presented for action at the Annual Meeting.

(ii) Except as otherwise required by law, nothing in this
Section 2 shall obligate the Corporation or the Board of Directors to include in any proxy statement or other stockholder communication distributed on behalf of the Corporation or the Board of Directors information with respect to any nominee for director submitted by a stockholder.

(iii) Notwithstanding the foregoing provisions of this Section 2, if the stockholder (or a qualified representative of the stockholder) does not appear at the Annual or special meeting of stockholders of the Corporation to present a nomination, such nomination shall be disregarded, notwithstanding the proxies in respect of such vote that may have been received by the Corporation. For purposes of this Section 2, to be considered a qualified representative of the stockholder, a person must be authorized by a written instrument executed by such stockholder or an electronic transmission delivered by such stockholder to act for such stockholder as proxy at the Annual or special meeting of stockholders and such person must produce such written instrument or electronic transmission, or a reliable reproduction of the written instrument or electronic transmission, at the Annual or special meeting of stockholders.

(iv) For purposes of this Bylaw, "Public Announcement" shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press or comparable national news service or in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to
Section 13, 14 or 15(d) of the Exchange Act.

(v) Notwithstanding the foregoing provisions of this Bylaw, a stockholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder with respect to the matters set forth in this Bylaw. Nothing in this Bylaw shall be deemed to affect any rights of (a) stockholders to request inclusion of proposals in the Corporation's proxy statement pursuant to Rule 14a-8 under the Exchange Act or (b) the holders of any series of Undesignated Preferred Stock to elect directors under specified circumstances.

SECTION 3. Special Meetings. Except as otherwise required by statute and subject to the rights, if any, of the holders of any series of Undesignated Preferred Stock, special meetings of the stockholders of the Corporation may be called only by the Board of Directors acting pursuant to a resolution approved by the affirmative vote of a majority of the directors then in office. Only those matters set forth in the notice of the special meeting may be considered or acted upon at a special meeting of stockholders of the Corporation.

3

SECTION 4. Notice of Meetings; Adjournments. A notice of each Annual Meeting stating the hour, date and place, if any, of such Annual Meeting shall be given not less than 10 days nor more than 60 days before the Annual Meeting, to each stockholder entitled to vote thereat by delivering such notice to such stockholder or by mailing it, postage prepaid, addressed to such stockholder at the address of such stockholder as it appears on the Corporation's stock transfer books.

Notice of all special meetings of stockholders shall be given in the same manner as provided for Annual Meetings, except that the notice of all special meetings shall state the purpose or purposes for which the meeting has been called.

Notice of an Annual Meeting or special meeting of stockholders need not be given to a stockholder if a waiver of notice is executed before or after such meeting by such stockholder or if such stockholder attends such meeting, unless such attendance is for the express purpose of objecting at the beginning of the meeting to the transaction of any business because the meeting was not lawfully called or convened.

The Board of Directors may postpone and reschedule any previously scheduled Annual Meeting or special meeting of stockholders and any record date with respect thereto, regardless of whether any notice or public disclosure with respect to any such meeting has been sent or made pursuant to Section 2 of this Article I of these Bylaws or otherwise. In no event shall the Public Announcement of an adjournment, postponement or rescheduling of any previously scheduled meeting of stockholders commence a new time period for the giving of a stockholder's notice under Section 2 of this Article I of these Bylaws.

When any meeting is convened, the presiding officer may adjourn the meeting if (a) no quorum is present for the transaction of business, (b) the Board of Directors determines that adjournment is necessary or appropriate to enable the stockholders to consider fully information which the Board of Directors determines has not been made sufficiently or timely available to stockholders, or (c) the Board of Directors determines that adjournment is otherwise in the best interests of the Corporation. When any Annual Meeting or special meeting of stockholders is adjourned to another hour, date or place, notice need not be given of the adjourned meeting other than an announcement at the meeting at which the adjournment is taken of the hour, date and place, if any, to which the meeting is adjourned and the means of remote communications, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such adjourned meeting; provided, however, that if the adjournment is for more than 30 days, or if after the adjournment a new record date is fixed for the adjourned meeting, notice of the adjourned meeting and the means of remote communications, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such adjourned meeting shall be given to each stockholder of record entitled to vote thereat and each stockholder who, by law or under the Certificate of Incorporation of the Corporation (as the same may hereafter be amended and/or restated, the "Certificate") or these Bylaws, is entitled to such notice.

SECTION 5. Quorum. A majority of the shares entitled to vote, present in person or represented by proxy, shall constitute a quorum at any meeting of stockholders. If less than a quorum is present at a meeting, the holders of voting stock representing a majority of the voting power present at the meeting or the presiding officer may adjourn the meeting from time to time,

4

and the meeting may be held as adjourned without further notice, except as provided in Section 4 of this Article I. At such adjourned meeting at which a quorum is present, any business may be transacted which might have been transacted at the meeting as originally noticed. The stockholders present at a duly constituted meeting may continue to transact business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum. When a specified item of business requires a vote by a class or series (if the Corporation shall then have outstanding shares of more than one class or series) voting as a class or series, the holders of a majority of the shares of such class or series shall constitute a quorum (as to such class or series) for the transaction of such item of business.

SECTION 6. Voting and Proxies. Stockholders shall have one vote for each share of stock entitled to vote owned by them of record according to the stock ledger of the Corporation, unless otherwise provided by law or by the Certificate. Stockholders may vote either (a) in person, (b) by written proxy or
(c) by a transmission permitted by Section 212(c) of the Delaware General Corporation Law ("DGCL"). Any copy, facsimile telecommunication or other reliable reproduction of the writing or transmission permitted by Section 212(c) of the DGCL may be substituted for or used in lieu of the original writing or transmission for any and all purposes for which the original writing or transmission could be used, provided that such copy, facsimile telecommunication or other reproduction shall be a complete reproduction of the entire original writing or transmission. Proxies shall be filed in accordance with the procedures established for the meeting of stockholders. At each meeting of the stockholders, and before any voting commences, all proxies filed at or before the meeting shall be submitted to and examined by the secretary or a person designated by the secretary, and no shares may be represented or voted under a proxy that has been found to be invalid or irregular. Except as otherwise limited therein or as otherwise provided by law, proxies authorizing a person to vote at a specific meeting shall entitle the persons authorized thereby to vote at any adjournment of such meeting, but they shall not be valid after final adjournment of such meeting. A proxy with respect to stock held in the name of two or more persons shall be valid if executed by or on behalf of any one of them unless at or prior to the exercise of the proxy the Corporation receives a specific written notice to the contrary from any one of them.

SECTION 7. Action at Meeting. When a quorum is present at any meeting of stockholders, any matter before any such meeting (other than an election of a director or directors) shall be decided by a majority of the votes properly cast for and against such matter, except where a larger vote is required by law, by the Certificate or by these Bylaws. Any election of directors by stockholders shall be determined by a plurality of the votes properly cast on the election of directors.

SECTION 8. Stockholder Lists. The Secretary or an Assistant Secretary (or the Corporation's transfer agent or other person authorized by these Bylaws or by law) shall prepare and make, at least 10 days before every Annual Meeting or special meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for a period of at least 10 days prior to the meeting in the manner provided by law. The list shall also be open to the examination of any stockholder during the whole time of the meeting as provided by law.

5

SECTION 9. Presiding Officer. The Chairman of the Board, if one is elected, or if not elected or in his or her absence, the President shall preside at all Annual Meetings or special meetings of stockholders and shall have the power, among other things, to adjourn such meeting at any time and from time to time, subject to Sections 4 and 5 of this Article I. The order of business and all other matters of procedure at any meeting of the stockholders shall be determined by the presiding officer.

SECTION 10. Inspectors of Elections. The Corporation shall, in advance of any meeting of stockholders, appoint one or more inspectors to act at the meeting and make a written report thereof. The Corporation may designate one or more persons as alternate inspectors to replace any inspector who fails to act. If no inspector or alternate is able to act at a meeting of stockholders, the presiding officer shall appoint one or more inspectors to act at the meeting. Any inspector may, but need not, be an officer, employee or agent of the Corporation. Each inspector, before entering upon the discharge of his or her duties, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of his or her ability. The inspectors shall determine the number of shares of stock outstanding and the voting power of each, the shares of stock represented at the meeting, the existence of a quorum, and the validity and effect of proxies, and shall receive votes or ballots, hear and determine all challenges and questions arising in connection with the right to vote, count and tabulate all votes or ballots, determine the result, and do such acts as are proper to conduct the election or vote with fairness to all stockholders. On request of the person presiding at the meeting, the inspector or inspectors, if any, shall make a report in writing if any challenge, question or matter determined by such inspector or inspectors and execute a certificate of any fact found by such inspector or inspectors. The presiding officer may review all determinations made by the inspectors, and in so doing the presiding officer shall be entitled to exercise his or her sole judgment and discretion and he or she shall not be bound by any determinations made by the inspectors. All determinations by the inspectors and, if applicable, the presiding officer, shall be subject to further review by any court of competent jurisdiction. No candidate who is a candidate for an office in an election may serve as an inspector at such election The inspectors may appoint or retain other persons or entities to assist the inspectors in the performance of the duties of the inspectors.

SECTION 11. Conduct of Meetings. The date and time of the opening and closing of the polls for each matter upon which the stockholders will vote at a meeting shall be announced at the meeting by the person presiding over the meeting. The Board of Directors may adopt by resolution such rules and regulations for the conduct of the meeting of stockholders as it shall deem appropriate. Except to the extent inconsistent with such rules or regulations as may be adopted by the Board of Directors, the person presiding over any meeting of stockholders shall have the right and authority to convene the meeting, to prescribe such rules, regulations and procedures and to do all such acts as, in the judgment of such presiding person, are appropriate for the conduct of the meeting. Such rules, regulations or procedures, whether adopted by the Board of Directors or prescribed by the presiding person of the meeting, may include, without limitation, the following: (a) establishment of an agenda or order of business for the meeting; (b) rules and procedures for maintaining order at the meeting and safety of those present, (c) limitation on attendance at or participation in the meeting to stockholders of record of the Corporation, their duly authorized and constituted proxies or such other persons as the presiding

For purposes of this Section 10, the total number of directors includes any unfilled vacancies on the Board of Directors.

(a) Actions, Suits and Proceedings Other than By or In the Right of the Corporation. Each Director and Officer shall be indemnified and held harmless by the Corporation against any and all Expenses and Liabilities that are incurred or paid by such Director or Officer or on such Director's or Officer's behalf in connection with any Proceeding or any claim, issue or matter therein (other than an action by or in the right of the Corporation), which such Director or Officer is, or is threatened to be made, a party to or participant in by reason of such Director's or Officer's Corporate Status, if such Director or Officer acted in good faith and in a manner such Director or Officer reasonably believed to be in or not opposed to the best interests of the Corporation and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful.

15

(c) Rights of Indemnification. The rights of indemnification provided by this Section 2 shall continue as to a Director or Officer after he or she has ceased to be a Director or Officer and shall inure to the benefit of his or her heirs, executors, administrators and personal representatives. Notwithstanding the foregoing, the Corporation shall indemnify any Director or Officer seeking indemnification in connection with a Proceeding initiated by such Director or Officer only if such Proceeding was authorized in advance by the Board of Directors of the Corporation, unless such Proceeding was brought to enforce an Officer or Director's rights to indemnification or, in the case of Directors, advancement of Expenses under these Bylaws in accordance with the provisions set forth herein.

SECTION 3. Indemnification of Non-Officer Employees. Subject to the operation of Section 4 of this Article V of these Bylaws, each Non-Officer Employee may, in the discretion of the Board of Directors of the Corporation, be indemnified by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended, against any or all Expenses and Liabilities that are incurred by such Non-Officer Employee or on such Non-Officer Employee's behalf in connection with any threatened, pending or completed Proceeding, or any claim, issue or matter therein, which such Non-Officer Employee is, or is threatened to be made, a party to or participant in by reason of such Non-Officer Employee's Corporate Status, if such Non-Officer Employee acted in good faith and in a manner such Non-Officer Employee reasonably believed to be in or not opposed to the best interests of the Corporation and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. The rights of indemnification provided by this Section 3 shall exist as to a Non-Officer Employee after he or she has ceased to be a Non-Officer Employee and shall inure to the benefit of his or her heirs, personal representatives, executors and administrators. Notwithstanding the foregoing, the Corporation may indemnify any Non-Officer Employee seeking indemnification in connection with a Proceeding initiated by such Non-Officer Employee only if such Proceeding was authorized in advance by the Board of Directors of the Corporation.

SECTION 4. Good Faith. Unless ordered by a court, no indemnification shall be provided pursuant to this Article V to a Director, to an Officer or to a Non-Officer Employee unless a determination shall have been made that such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation and, with respect to any criminal Proceeding, such person had no reasonable cause to believe his or her conduct was unlawful. Such determination shall be made by (a) a majority vote of the Disinterested Directors, even though less than a quorum of the Board of Directors, (b) a committee comprised of Disinterested Directors, such committee having been designated by a majority vote of the Disinterested Directors (even though less than a quorum), (c) if there are no such Disinterested Directors, or if a majority of Disinterested Directors so directs, by independent legal counsel in a written opinion, or (d) by the stockholders of the Corporation.

SECTION 5. Advancement of Expenses to Directors Prior to Final Disposition. The Corporation shall advance all Expenses incurred by or on behalf of any Director in connection with any Proceeding in which such Director is involved by reason of such Director's Corporate Status within 30 days after the receipt by the Corporation of a written statement from such Director requesting such advance or advances from time to time, whether prior to or after final

16

disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by such Director and shall be preceded or accompanied by an undertaking by or on behalf of such Director to repay any Expenses so advanced if it shall ultimately be determined that such Director is not entitled to be indemnified against such Expenses. Notwithstanding the foregoing, the Corporation shall advance all Expenses incurred by or on behalf of any Director seeking advancement of expenses hereunder in connection with a Proceeding initiated by such Director only if such Proceeding was (i) authorized by the Board of Directors of the Corporation, or (ii) brought to enforce such Director's rights to indemnification or advancement of Expenses under these Bylaws.

(a) If a claim for advancement of Expenses hereunder by a Director is not paid in full by the Corporation within 30 days after receipt by the Corporation of documentation of Expenses and the required undertaking, such Director may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and if successful in whole or in part, such Director shall also be entitled to be paid the expenses of prosecuting such claim. The failure of the Corporation (including its Board of Directors or any committee thereof, independent legal counsel, or stockholders) to make a determination concerning the permissibility of such advancement of Expenses under this Article V shall not be a defense to the action and shall not create a presumption that such advancement is not permissible. The burden of proving that a Director is not entitled to an advancement of expenses shall be on the Corporation.

(b) In any suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Corporation shall be entitled to recover such expenses upon a final adjudication that the Director has not met any applicable standard for indemnification set forth in the DGCL.

SECTION 6. Advancement of Expenses to Officers and Non-Officer Employees Prior to Final Disposition. The Corporation may, at the discretion of the Board of Directors of the Corporation, advance any or all Expenses incurred by or on behalf of any Officer or any Non-Officer Employee in connection with any Proceeding in which such is involved by reason of the Corporate Status of such Officer or Non-Officer Employee upon the receipt by the Corporation of a statement or statements from such Officer or Non-Officer Employee requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by such Officer or Non-Officer Employee and shall be preceded or accompanied by an undertaking by or on behalf of such to repay any Expenses so advanced if it shall ultimately be determined that such Officer or Non-Officer Employee is not entitled to be indemnified against such Expenses.

In any suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Corporation shall be entitled to recover such expenses upon a final adjudication that the Officer or Non-Officer Employee has not met any applicable standard for indemnification set forth in the DGCL.

SECTION 7. Contractual Nature of Rights. The foregoing provisions of this Article V shall be deemed to be a contract between the Corporation and each Director and Officer entitled

17

to the benefits hereof at any time while this Article V is in effect, and any repeal or modification thereof shall not affect any rights or obligations then existing with respect to any state of facts then or theretofore existing or any Proceeding theretofore or thereafter brought based in whole or in part upon any such state of facts.

(a) If a claim for indemnification hereunder by a Director or Officer is not paid in full by the Corporation within 60 days after receipt by the Corporation of a written claim for indemnification, such Director or Officer may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim, and if successful in whole or in part, such Director or Officer shall also be entitled to be paid the expenses of prosecuting such claim. The failure of the Corporation (including its Board of Directors or any committee thereof, independent legal counsel, or stockholders) to make a determination concerning the permissibility of such indemnification under this Article V shall not be a defense to the action and shall not create a presumption that such indemnification is not permissible. The burden of proving that a Director or Officer is not entitled to indemnification shall be on the Corporation.

(b) In any suit brought by a Director or Officer to enforce a right to indemnification hereunder, it shall be a defense that such Director or Officer has not met any applicable standard for indemnification set forth in the DGCL.

SECTION 8. Non-Exclusivity of Rights. The rights to indemnification and to advancement of Expenses set forth in this Article V shall not be exclusive of any other right which any Director, Officer, or Non-Officer Employee may have or hereafter acquire under any statute, provision of the Certificate or these Bylaws, agreement, vote of stockholders or Disinterested Directors or otherwise.

SECTION 9. Insurance. The Corporation may maintain insurance, at its expense, to protect itself and any Director, Officer or Non-Officer Employee against any liability of any character asserted against or incurred by the Corporation or any such Director, Officer or Non-Officer Employee, or arising out of any such person's Corporate Status, whether or not the Corporation would have the power to indemnify such person against such liability under the DGCL or the provisions of this Article V.

SECTION 10. Other Indemnification. The Corporation's obligation, if any, to indemnify any person under this Article V as a result of such person serving, at the request of the Corporation, as a director, partner, trustee, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall be reduced by any amount such person may collect as indemnification from such other corporation, partnership, joint venture, trust, employee benefit plan or enterprise.

Exhibit 10.24

TRANSITION AGREEMENT

This Transition Agreement (the "Agreement") is being entered into this __ day of __________, 2006 (the "Effective Date") by and between _________ and Altra Industrial Motion, Inc., its subsidiaries and affiliate companies (collectively, the "Company").

1. Except as otherwise provided herein, the term of this Agreement will be from the Effective Date until one year following the closing date of the sale (the "Closing Date") of the Altra Industrial Motion (the "Business) of the Company, unless earlier terminated as provided below.

2. During the term of this Agreement, you will continue to devote your entire business skill, time, and effort diligently to the affairs of the Business and you will perform all such duties, and otherwise conduct yourself, in a manner reasonably determined to promote the best interests of the Company.

3. Notwithstanding any other provision of this Agreement, your eligibility to receive from the Company a Severance Benefit under this Agreement is expressly contingent on the sale of all of the Business (whether in one transaction or several) or the sale of the business unit within the Business for which you provide services to a Buyer (or Buyers) on or before March 31, 2007. If neither all of the Business nor the business unit within the Business for which you provide services is sold before March 31, 2007, you shall not be eligible to receive any Severance Benefit pursuant to this Agreement and this Agreement shall terminate on April 1, 2007. For the purposes of this Agreement, a sale shall not be deemed to occur until the transaction closes, nor shall a sale be deemed to occur if the Company goes public.

4. Severance Benefit Eligibility

a. In addition to the requirements in Section 3 above, you will be eligible for a Severance Benefit only if: you satisfy the requirements of Section 5 and 6 herein; and if during the first year of your employment with the Buyer, your employment is terminated by the Buyer other than for Cause or you voluntarily resign for Good Reason.

b. If you are eligible for a Severance Benefit, it will be calculated based on 12 months of your base annual salary and will be paid to you in the form of salary continuation in accordance with the Company's regular payroll practices and procedures. The Severance Benefit also includes the following: if you elect to continue your health care and dental coverage through COBRA or any similar state law and provided you continue to authorize the required employee contributions for your share of the premiums, the Company will continue to pay its share of your premiums (at the same level of coverage as you have upon termination of employment) during the period of salary continuation. Please note that if you elect coverage


through COBRA, that such coverage begins after the benefits mentioned above end under the terms of this Agreement. For example, if you have 12 months of salary continuation, you will have the same amount of months of medical and dental coverage continuation before COBRA commences.

c. If payable, the Severance Benefit will not be included in determining the amount of any benefits under any of the Company's qualified or nonqualified employee benefit plans in which you may be a participant.

d. Any Severance benefit will cease immediately upon your securing employment after the end of your employment with the Company. You agree that if you do secure such employment during the period in which you are receiving Severance Benefit, you shall immediately notify the Company.

For purposes of this Agreement, the term "Cause" means: (i) your conviction(including without limitation by plea of guilty or no contest) of a misdemeanor crime involving fraud, dishonesty, or moral turpitude; (ii) your willful misconduct or negligence in the performance of your duties; (iii) your breach of this Agreement or any other agreement between you and the Company; or
(iv) any breach of your fiduciary duty or act of fraud, dishonesty, disloyalty, or embezzlement by you.

For purposes of this Agreement, the term "Good Reason" means: (i) a material diminution in your job responsibilities or (ii) a material reduction in your compensation or bonus opportunities.

5. To be eligible for a Severance Benefit, you must execute and deliver to the Company a General Release of Claims ("General Release") in the form attached hereto as Exhibit 1 or in such other form as the Company reasonably determines appropriate. You understand that you shall sign the General Release no earlier than the first business day after the last day of your employment.

6. In further consideration for the benefits described in Section 4 above, you agree to the following:

a. Return of Property; Intellectual Property Rights. Upon your termination of employment for any reason with the Company or at any time requested by the Company, you will return all property owned by the Company or containing information relating to the Company's business or customers, including files, documents, data and records (whether on paper, tapes, disks, or in any form, electronic or otherwise), office equipment, credit cards, and employee identification cards. You acknowledge that the Company is the rightful owner of any programs, ideas, inventions, discoveries, copyright material, or trademarks that

2

you may have originated or developed, or assisted in originating or developing, during your period of employment with the Company, where any such origination or development involved the use of Company time or resources, or the exercise of your responsibilities for or on behalf of the Company. You will at all times, both before and after termination of employment cooperate with the Company in executing and delivering documents and taking any other actions that are necessary or requested by the Company to assist the Company in patenting, copyrighting, or registering any programs, ideas, inventions, discoveries, copyright material, or trademarks, and to vest title thereto in the Company.

b. Proprietary and Confidential Information. You will at all times both during and after your employment with the Company preserve the confidentiality of all proprietary or confidential information and trade secrets of the Company, except to the extent that disclosure of such information is legally required, authorized in writing by the Company, or necessary in the performance of your duties on behalf of the Company. The phrase "proprietary or confidential information" includes without limitation information that has not been disclosed to the public or that has been disclosed to the public wrongfully or in breach of the disclosing party's obligations to the Company and that is treated as confidential within the business of the Company, such as strategic or tactical business plans; financial data, ideas, processes, methods, techniques, systems, patented or copyrighted information; documents relating to regulatory matters and correspondence with governmental entities; information concerning any past, pending, or threatened legal dispute; pricing and cost data; reports and analyses of business prospects; business transactions which are contemplated or planed; research data; personnel information and data; identities or lists of or information regarding users, purchasers, or customers of any of the Company's products or services; and other confidential matters pertaining to or known by the Company, including confidential information of a third party which you know or should know the Company is bound to protect.

c. Interference with Business Relations. During the period of your employment with the Company except in accordance with your duties and responsibilities on behalf of the Company, and for a period ending 24 months following your termination of employment from the Company for any reason, you will not, without the prior written consent of the Company, directly or indirectly on behalf of yourself or any other entity: (i) recruit, solicit, or hire any employee of the Company (or any person who had been employed by the Company within six months following your last day of employment with the Company) for employment or for retention as a consultant or service provider; (ii) solicit or induce, or in any manner attempt to solicit or induce, any client, customer, or prospective client or customer of the Company to

3

cease being, or not to become, a customer of the Company, or to divert any business of such customer or prospective customer or client from the Company; or (iii) otherwise interfere with, disrupt, or attempt to interfere with or disrupt, the relationship, contractual or otherwise, between the Company and any of its customers, clients, prospective customers or clients, suppliers, consultants, or employees.

d. You agree that for a period of two (2) years from the date of your termination, you will not accept employment with, provide advice, consulting services, or in any other capacity work for or provide services to companies that directly compete with the Company, including but not limited to the following companies (a list of Companies will be included when/if this document becomes officially effective) including their successors, assigns, parents, subsidiaries, divisions, or affiliates for one year following your termination date.

e. You agree that for two (2) full years from your termination date, you shall not solicit or service orders from (a list of Customers will be included here when/if this document becomes officially effective) for the purchase of products similar to those the Company manufactures and sells.

f. Other Agreements and Policies. The obligations imposed on you by this Section 6 are in addition to, and not in lieu of, any and all other policies or agreements of the Company regarding the subject matter of the foregoing obligations.

7. You acknowledge that the Company's customers and prospective customers are national and international in scope and that the terms of these covenants are necessary and reasonable and will not prevent you from earning a livelihood. You agree that your agreement to these covenants is a material inducement to the Company to enter into this Agreement and to make possible to you the benefits provided in this Agreement. You further agree that money damages may be insufficient as remedy for your breach of these covenants. Accordingly, you agree that, in addition to any other relief that may be available, the Company shall be entitled to specifically enforce these covenants, including without limitation by means of temporary, preliminary, and permanent injunctive relief. You also agree that should any court of competent jurisdiction find any portion of these covenants to be unenforceable for any reason, that the court shall modify such portion so that it is enforceable then enforce the covenant as modified. You further agree that if the Court is unwilling or unable to make such a modification, then it shall sever the unenforceable provision and shall enforce the remaining portions of these covenants as fully as possible so as to achieve the original intent of these covenants.

4

8. The Company will endeavor to have the Buyer assume this Agreement. If the Buyer assumes the Agreement, the Company will assign all of its rights and obligation under this Agreement to the Buyer; and if the Company makes such an assignment, all references in this Agreement (not including section 7) to "Company" will be deemed to refer to the Buyer on and after the effective date of such assignment, unless the context clearly requires a contrary meaning. The Company may otherwise assign its rights and obligations under this Agreement to another entity with or without your consent. Upon any assumption or assignment provided in this Section 7, the Company shall owe no further obligation to you under this Agreement. You may not assign your rights and obligations under this Agreement.

9. The payment of any benefits under this Agreement will be in lieu of, and not in addition to, any separation or severance benefits to which you may otherwise be entitled from the Company. In addition, no provision of this Agreement will require the Company to provide you with any payment, benefit, or grant that duplicates any payment, benefit or grant that you are entitled to receive under any Company compensation or benefit plan or other agreement or arrangement.

10. Nothing in this Agreement shall be construed as a right to continued employment with the Company and nothing in this Agreement limits the Company's right to terminate your employment with the Company at any time (including prior to the Closing Date) with or without cause or notice. The term of this Agreement shall end on your last day of employment if the term has not already ended.

11. Failure to insist upon strict compliance with any of the terms, covenants, or conditions of this Agreement will not be deemed a waiver of such term, covenant, or condition, nor will any waiver or relinquishment of any tight or power hereunder at any one or more times be deemed a waiver or relinquishment of such right or power at any other time or times.

12. The Company may withhold from any benefits payable under this Agreement all taxes, deductions, and withholdings that the Company determines to be required pursuant to any law, regulation, or ruling. However, it is your obligation to pay all required taxes on any amounts provided under this Agreement, regardless of whether withholding is required.

13. Except to the extent otherwise required by law, you will not disclose, in whole or in part, any of the terms of this Agreement. However, you may disclose the terms of this Agreement to your spouse and to your legal or financial advisor, provided that you take all reasonable measures to assure that he or she does not disclose the terms of this Agreement to a third party except as otherwise required by law. In addition, notwithstanding anything in this paragraph to the

5

contrary, you may disclose to any and all persons, without limitation or any kind, the tax treatment and tax structure of the transaction and all materials of any kind (including opinions and other tax analyses) that are provided to you relating to such tax treatment and tax structure.

14. Dispute Resolution.

a. The parties agree that, except for any claims pursuant to Section 6 of this Agreement, they shall submit to arbitration and resolve in accordance with the procedures specified in this Section 13 any and all disputes arising from or relating to this Agreement. The parties further agree that the arbitration process agreed upon herein shall be the exclusive means for resolving all disputes made subject to arbitration herein.

b. Notwithstanding any other choice of law provisions in the Agreement, the interpretation and enforcement of the arbitration provisions of this Agreement shall be governed exclusively by the Federal Arbitration Act ("FAA"), and shall otherwise be governed by the law of the State of Delaware.

c. These arbitration provisions shall not prevent the Company from obtaining injunctive relief from a court of competent jurisdiction to enforce any obligations of the Agreement; including without limitation issues concerning covenants not to compete, the use of trade secrets or confidential commercial information (which are excluded from this arbitration process as set forth above), or any other matters for which the Company in its sole discretion may require provisional relief pending a decision on the merits by the arbitrator.

d. Any arbitration hereunder shall be conducted under the Model Employment Procedures of the American Arbitration Association ("AAA"), as modified herein, and, unless otherwise agreed by the parties, shall take place in Boston, Massachusetts, at a place designated by the AAA.

e. Each party shall be responsible for its costs (including attorneys' fees) incurred in any arbitration, and the arbitrator shall not have the authority to include all or any portion of said costs (including attorneys' fees) in an award, regardless of which party prevails. The costs and fees of the arbitrator and of the AAA shall be borne equally by the parties.

f. Except as set forth herein, the arbitrator shall have authority to award any remedy or relief that a court of the State of Delaware could grant in conformity to applicable law.

6

g. With respect to any claims pursuant to section 6 of this Agreement, such claims too will be governed by the law of the State of Delaware, and both you and the Company agree to and submit to the jurisdiction and venue of any state or federal court located in the state where the Company maintains its headquarters.

15. The provisions contained in this Agreement and within the General Release will each constitute a separate agreement independently supported by good and adequate consideration, and will each be severable from the other provisions of the Agreement and the General Release. If a court of competent jurisdiction or an arbitrator determines that any term, provision, or portion of this Agreement or the General Release is void, illegal, or unenforceable, the other terms, provisions, and portions of this Agreement and General Release will remain in full force and effect, and the terms, provisions, and portions that are determined to be void, illegal, or unenforceable will either be limited so that they will remain in effect to the extent permissible by law, or such court or arbitrator will substitute, to the extent enforceable, provisions similar thereto or other provisions, so as to provide to the Company and you, to the fullest extent permitted by applicable law, the benefits intended by this Agreement and the General Release.

16. The provisions of this Agreement as well as the General Release shall survive the termination of this Agreement according to their terms.

17. This Agreement sets forth the entire understanding of you and the Company with respect to severance or separation pay matters, and supersedes all prior agreements and communications, whether oral or written, between you and the Company regarding such matters. This Agreement will not be modified except by the written agreement of you and the Company.

18. You acknowledge that you have read and understand this Agreement and execute it voluntarily and without coercion. You further acknowledge that you have been advised in writing of your opportunity to consult with counsel and that you have been given a more than sufficient period of time to consider the terms of this Agreement.
