The following discussion of the financial condition and results of operations of Altra Holdings, Inc. should be read together with the audited financial statements of Altra Holdings, Inc. and related notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2008.

General

Altra Holdings, Inc. is the parent company of Altra Industrial Motion, Inc. ("Altra Industrial") and owns 100% of Altra Industrial's outstanding capital stock. Altra Industrial, directly or indirectly, owns 100% of the capital stock of its 48 subsidiaries. The following chart illustrates a summary of our corporate structure:

[[Image Removed]]

Although we were incorporated in Delaware in 2004, much of our current business has its roots with the prior acquisition by Colfax Corporation, or Colfax, of a series of power transmission businesses. In December 1996, Colfax acquired the MPT group of Zurn Technologies, Inc. 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 Power Transmission Holding LLC, or PTH, in June 2004 to serve as a holding company for all of these power transmission businesses. Boston Gear was established in 1877, Warner Electric, Inc. in 1927, and Wichita Clutch in 1949.

On November 30, 2004, we acquired our original core business through the acquisition of PTH from Colfax. We refer to this transaction as the PTH Acquisition.

On October 22, 2004, The Kilian Company, or Kilian, a company formed at the direction of Genstar Capital, acquired Kilian Manufacturing Corporation from Timken U.S. Corporation. At the completion of the PTH Acquisition, (i) all of the outstanding shares of Kilian capital stock were exchanged for shares of our capital stock and (ii) Kilian and its subsidiaries were transferred to our wholly owned subsidiary.

On February 10, 2006, we purchased all of the outstanding share capital of Hay Hall Holdings Limited, or Hay Hall. 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.

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 manufacturers of industrial clutches and brakes in the world.

On May 18, 2006, we acquired substantially all of the assets of Bear Linear. 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 our sourcing alliance with a low cost country manufacturer, were critical components in our strategic expansion within the motion control market.

On April 5, 2007, the Company acquired all of the outstanding shares of TB Wood's. TB Wood's is an established designer, manufacturer, and marketer of mechanical and electronic industrial power transmission products with a history dating back to 1857.

On October 5, 2007, we acquired substantially all of the assets of All Power Transmission Manufacturing, Inc., or All Power.

On December 31, 2007, we sold the TB Wood's adjustable speed drives business or Electronics Division, to Vacon, Inc. We sold the Electronics Division in order to continue our strategic focus on our core electro-mechanical power transmission business.

The subsidiaries of Altra Industrial design, produce and market a wide range of mechanical power transmission ("MPT") and motion control products. The business conducted at our subsidiaries is organized into five operating segments; Electromagnetic Clutches & Brakes, Heavy Duty Clutches & Brakes, Overrunning Clutches & Engineered Bearing Assemblies, Engineered Couplings and Gearing & Belted Drives. We have a presence in over 70 countries. Our global sales and marketing network includes over 1,000 direct original equipment manufacturers ("OEM") and over 3,000 distributor outlets. We are headquartered in Braintree, Massachusetts.

Our operating segments, principal brands and principal markets are set forth below:

Business Outlook

Our future financial performance depends, in large part, on conditions in the markets that we serve and on the U.S. and global economies in general. During November and December 2008, we saw a significant change in economic conditions both in North America and internationally as most of our end markets experienced dramatic downturns. During the fourth quarter of 2008, we began to see several of our distributors

and OEM customers implement inventory reduction programs which continued throughout the first two quarters of 2009. Beginning in the third quarter of 2009, it appeared that inventory reduction efforts by our customers began to come to an end as sales to our largest distribution customers improved during the third quarter. However, we continue to expect weakness in order rates for the remainder of 2009 as compared with 2008.

In response to the continued challenging economic conditions of 2009, we have taken and continue to take swift and aggressive actions to reduce our expenses and maximize near-term profitability. Our cost-reduction initiatives are centered on three areas: workforce cutbacks, plant consolidations and procurement and other cost reductions. In February 2009, the Company's discretionary 401(k) match was suspended and a temporary reduction in executive compensation was initiated. On June 1, 2009, the Company announced the temporary suspension of all Company contributions to the 401(k) plan. We also have announced a general hiring freeze, a freeze of all non-union employee salaries and reduced work schedules. During the year to date period ended September 26, 2009, we incurred $5.4 million of restructuring expense including a $2.0 million non-cash charge primarily related to impairment charges at the Mount Pleasant and South Beloit facilities that are expected to close in 2009 and in the first quarter of 2010, respectively. The remaining expense relates mainly to severance. We expect to incur between an additional $2.5 and $3.5 million of expenses associated with workforce reduction and consolidation of facilities in 2009 and between $1.3 million and $1.9 million of such additional expenses in 2010. Beginning in 2010, we expect to see annualized savings from the headcount reductions and consolidation of facilities of approximately $30 million. We expect savings in 2009 to be $17.9 million. Including procurement and other cost reduction efforts, annualized savings would be approximately $77 million (approximately $60 million in 2009). We estimate that once volume returns to prior year levels, between $10 and $12 million of these savings will be permanent in nature.

We will continue our strong focus on working capital management and cash flow generation with the intent of improving our liquidity by reducing inventory and accounts receivable levels. As of September 26, 2009, we have a cash balance of $71.9 million.

Critical Accounting Policies

The preparation of our condensed consolidated financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires management to make judgments, assumptions and estimates that affect our reported amounts of assets, revenues and expenses, as well as related disclosure of contingent assets and liabilities. We base our estimates on past experiences and other assumptions we believe to be appropriate, and we evaluate these estimates on an on-going basis. Management believes there have been no significant changes in our critical accounting policies since December 31, 2008, except as listed below. See the discussion of critical accounting policies in our Annual Report on Form 10-K for the year ended December 31, 2008.

Goodwill, Intangibles and other long-lived assets. In connection with our acquisitions, goodwill and intangible assets were identified and recorded at their fair value. We recorded intangible assets for customer relationships, trade names and trademarks, product technology, patents and goodwill. In valuing the customer relationships, trade names and trademarks, 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 financial information is subject to risk if our estimates are incorrect. The most significant estimate relates to our projected revenues and profitability. If we do not meet the projected revenues and profitability 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 4% 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 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 ranging from 8 years to 16 years. 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. 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. Additionally, we believe that our trade names and trademarks will continue to generate product sales for an indefinite period.

As of December 31, 2008, goodwill was allocated to each of our twenty identified reporting units. We conducted an annual impairment review of goodwill and indefinite lived intangible assets as of December 31, 2008 at each of these reporting units.

The breakdown of reporting units by acquisition and acquisition date are as follows:

  Colfax acquisition - November 30, 2004     12 reporting units
  Hay Hall acquisition - February 10, 2006   5 reporting units (including Huco)
  Warner Linear acquisition - May 18, 2006   1 reporting unit
  TB Wood's acquisition - April 5, 2007      1 reporting unit
  All Power Transmission - October 5, 2007   1 reporting unit

Beginning in the fourth quarter of 2008, almost all of our reporting units were impacted by the general economic decline. The decline in our weekly order rates was significant and almost immediate. Between the week of November 7, 2008 and November 14, 2008 order rates declined 21%. Prior to that week, order rates had been flat or increasing for over a year. On a consolidated basis weekly order rates from the week of November 14, 2008 through the final full week of the year, (the week of December 19, 2008) decreased an additional 33%.

As part of the annual goodwill impairment assessment we estimated the fair value of each of our reporting units using an income approach. We forecasted future cash flows by reporting unit for each of the next five years and applied a long term growth rate to the final year of forecasted cash flows. The cash flows were then discounted using our estimated discount rate. The forecasts of revenue and profitability growth for use in the long-range plan and the discount rate were the key assumptions in our intangible fair value analysis. The following are the assumptions used in 2008 and 2007 in the calculation of estimated fair value for the reporting units that recorded a goodwill impairment as of December 31, 2008 (Huco, Warner Linear and TB Woods) and the reporting units that are at risk of recording a goodwill impairment in the future (TB Woods, Ameridrives, Matrix, All Power and Boston Gear). No goodwill remains at Huco or Warner Linear subsequent to the goodwill impairment in 2008.:

A continuation of the significant decrease in order rates in the final weeks of 2008 and into 2009 was a key assumption when developing our long-term revenue and profitability plan for our goodwill impairment analysis as of December 31, 2008.
