for

$165,000,000 principal amount of
9% Senior Secured Notes due 2011
registered under the Securities Act of 1933

We are offering to exchange our outstanding notes described above for the new, registered notes described above. In this prospectus we refer to the outstanding notes as the "old notes" and our new notes as the "registered notes," and we refer to the old notes and the registered notes, together, as the "notes." The form and terms of the registered notes are identical in all material respects to the form and terms of the old notes, except for transfer restrictions, registration rights and additional interest payment provisions relating only to the old notes. We do not intend to apply to have any notes listed on any securities exchange or automated quotation system and there may be no active trading market for them.

Material Terms of the Exchange Offer

•: The exchange offer expires at 5:00 p.m., New York City time, on , 2005, unless extended. Whether or not the exchange offer is extended, the time at which it ultimately expires is referred to in this prospectus as the time of expiration.
•: The only conditions to completing the exchange offer are that the exchange offer not violate any applicable law, regulation or interpretation of the staff of the Securities and Exchange Commission and that no injunction, order or decree of any court or governmental agency that would prohibit, prevent or otherwise materially impair our ability to proceed with the exchange offer shall be in effect.
•: All old notes that are validly tendered and not validly withdrawn will be exchanged.
•: Tenders of old notes in the exchange offer may be withdrawn at any time prior to the time of expiration.

Any broker-dealer that acquired old notes as a result of market-making or other trading activities and receives registered notes for its own account in exchange for those old notes must acknowledge that it will deliver a prospectus in connection with any resale of those registered notes. The letter of transmittal states that, by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer for that purpose. We have agreed that, for a period ending on the earlier of (a) 180 days after the time of expiration and (b) the date on which broker-dealers are no longer required to deliver a prospectus in connection with market-making or other trading activities, we will make this prospectus available to any broker-dealer for use in connection with any resales by that broker-dealer.

PROSPECTUS SUMMARY

This summary highlights selected information about us. This is only a summary and does not contain all of the information that may be important to you. In addition to this summary, you should carefully read this prospectus in its entirety before making an investment decision. In particular, you should read the section titled "Risk Factors" and "Management's Discussion and Analysis of Results of Operations and Financial Condition" and the consolidated financial statements and notes related to those statements included elsewhere in this prospectus. In this prospectus, unless the context requires otherwise, references to "Altra," "we," "us" and "our" refer to Altra Industrial Motion, Inc. and its wholly owned subsidiaries. References to "Altra Holdings" refer to Altra Industrial Holdings, Inc., our parent company.

Our Company

We are a leading multinational designer, producer and marketer of a wide range of mechanical power transmission products. We sell our products in over 70 countries to over 400 direct OEM customers and over 3,000 distributor outlets through our direct sales force consisting of over 250 sales and marketing personnel and our independent sales representatives. Our products are frequently used in critical applications, such as fail-safe brakes for elevators, wheelchairs and forklifts. We also provide products for use 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.

We market our products under our well recognized and established manufacturing brand names, many of which have achieved the #1 or #2 position in terms of brand awareness in their respective product categories according to a 2003 Motion Systems Design magazine survey. Our leading brands are Ameridrives, Boston Gear, Warner Electric, Formsprag Clutch, Industrial Clutch, Kilian, Marland Clutch, Nuttall Gear, Stieber and Wichita Clutch. All of these brands have been in existence for over 50 years.

Industry Overview

Based on industry data supplied by Penton Information Services, or Penton, we estimate that industrial power transmission products generated worldwide revenues of approximately $57 billion in 2003, of which approximately $25 billion was generated in the United States. These products are used to generate, transmit, control and transform mechanical energy. The industrial power transmission industry can be divided into three segments: mechanical power transmission products, motors and generators and adjustable speed drives. We compete primarily in the mechanical power transmission segment which, based on industry data, we estimate was a $29 billion global market in 2003, of which approximately 57% was represented by aftermarket parts revenues. According to The Freedonia Group, Inc., an independent market research firm, the mechanical power transmission components subsegment is expected to increase 6.1% compounded annually from 2003 to 2008.

The global mechanical power transmission market is highly fragmented, with over 1,000 small manufacturers. While smaller companies tend to be focused on regional niche markets with narrow product lines, larger companies that generate 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 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 can 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.

Business Strengths

We believe the following business strengths have allowed us to develop and maintain a leading position within the mechanical power transmission industry:

•: Leading Brand Awareness.
•: Strong Distribution Channels.
•: Large Installed Base of Products with Stable, Recurring Revenue Streams.
•: Diversified Revenue Base.
•: Proven Operational Efficiencies.
•: Experienced Senior Management Team.

Business Strategy

By pursuing the following strategies, we intend to continue to increase our sales through a combination of organic growth and acquisitions while improving our profitability through strategic cost reduction initiatives.

•

Increase Market Share in our Existing Markets by:

•: Leveraging our Sales and Distribution Network;
•: Focusing on Strategic Marketing; and
•: Accelerating New Product and Technology Development.

•

Capitalize on Growth and Sourcing Opportunities in the Asia-Pacific Market.

•

Continue to Improve Operational and Manufacturing Efficiencies.

•

Selectively Pursue Acquisition, Alliance and Partnership Opportunities.

Risk Factors

Our ability to attain our objectives depends upon our success in addressing risks relating to our business and the industries we serve, including the following:

•: We operate in the highly competitive mechanical power transmission industry.
•: Our business is impacted by general economic conditions and we serve customers in cyclical industries.
•: We may have difficulty predicting future operating results due to both internal and external factors affecting our business and operations.
•: We rely on independent distributors.
•: We are subject to risks associated with changing technology and manufacturing techniques, which could place us at a competitive disadvantage.
•: Our international operations are subject to uncertainties that could affect our operating results.
•: Because we sell our products on a purchase order basis and rely on estimated forecasts of our OEM customers' needs, inaccurate forecasts could adversely affect our business.
•: The materials used to produce our products are subject to price fluctuations that could increase costs of production and adversely affect profitability.

•: Our future success depends on our ability to effectively integrate acquired companies and manage our growth.

Our Principal Equity Sponsor

Genstar Capital, L.P., or Genstar Capital, is a financial sponsor, formed in 1988 and based in San Francisco, with over $900 million of committed capital under management and has significant experience operating and investing in businesses. Genstar Capital's strategy is to make control-oriented investments or acquire companies with $50 million to $500 million in revenues in a variety of growth, buyout, recapitalization and consolidation transactions.

The Acquisition and Related Transactions

The Acquisition. On October 25, 2004, Altra Holdings, Inc., or Altra Holdings, a company formed at the direction of Genstar Capital and formerly named CPT Acquisition Corp., entered into a purchase agreement with Warner Electric Holding, Inc. and Colfax Corporation. Pursuant to the purchase agreement, Altra Holdings agreed to acquire Power Transmission Holding LLC, or PTH, for $180.0 million. PTH was organized in June 2004 to be the holding company for a group of companies comprising the power transmission business of Colfax Corporation. Altra Holdings assigned its rights and obligations under the purchase agreement to us and we funded the purchase price and related fees and expenses through (i) $40.0 million of equity and other investments by affiliates of Genstar Capital and other investors through Altra Holdings and (ii) the net proceeds of the offering of the old notes. On November 30, 2004, the closing of the acquisition, PTH was merged with and into us and its subsidiaries became our direct or indirect wholly owned subsidiaries. We refer to the acquisition of PTH as the "Acquisition."

Related Transactions. 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 and Kilian Holdings, Inc. Kilian financed the purchase price through (i) an $8.8 million equity investment by Genstar Capital and other investors and (ii) $13.0 million in borrowings under credit facilities. At the consummation of the Acquisition, (i) all of the outstanding shares of Kilian capital stock were exchanged for approximately $8.8 million of shares of Holdings capital stock and Kilian, then a subsidiary of Holdings, and its subsidiaries were transferred to us and become our direct or indirect wholly owned subsidiaries and (ii) net proceeds from the offering of the old notes were used to repay all of Kilian's outstanding borrowings (approximately $12.2. million) assumed by us when Kilian became our wholly owned subsidiaries.

We refer to the Acquisition, the transfer to us of Kilian and its subsidiaries, entering into our senior revolving credit facility, the use of proceeds from the offering of the old notes and other equity investments as the "Acquisition and Related Transactions."

Altra Industrial Motion, Inc. is a Delaware corporation and wholly owned subsidiary of Altra Holdings. Our headquarters are located at 14 Hayward St., Quincy, Massachusetts 02171 and our telephone number is (617) 328-3300. Altra Holdings is owned by affiliates of Genstar Capital, Caisse de depot et placement du Quebec and certain members of our senior management. For more information on the beneficial ownership of Altra Holdings, see "Security Ownership of Certain Beneficial Owners and Management."

Summary of the Terms of the Exchange Offer

On November 30, 2004, we issued $165.0 million aggregate principal amount of 9% Senior Secured Notes due 2011 in a transaction exempt from registration under the Securities Act of 1933. We refer to the issuance of the old notes in this prospectus as the "original issuance."

At the time of the original issuance, we entered into an agreement in which we agreed to register new notes, with substantially the same form and terms of the old notes, and to offer to exchange the registered notes for the old notes. This agreement is referred to in this prospectus as the "registration rights agreement."

Unless you are a broker-dealer and so long as you satisfy the conditions set forth below under "—Resales of the Registered Notes," we believe that the registered notes to be issued to you in the exchange offer may be resold by you without compliance with the registration and prospectus delivery provisions of the Securities Act. You should read the discussions under the headings "The Exchange Offer" for further information regarding the exchange offer.

Registration Rights Agreement		Under the registration rights agreement, we are obligated to offer to exchange the old notes for registered notes with terms identical in all material respects to the old notes. The exchange offer is intended to satisfy that obligation. After the exchange offer is complete, except as set forth in the next paragraph, you will no longer be entitled to any exchange or registration rights with respect to your old notes.
		The registration rights agreement requires us to file a registration statement for a continuous offering in accordance with Rule 415 under the Securities Act for your benefit if you would not receive freely tradeable registered notes in the exchange offer or you are ineligible to participate in the exchange offer and indicate that you wish to have your old notes registered under the Securities Act.
The Exchange Offer		We are offering to exchange $1,000 principal amount of 9% Senior Secured Notes due 2011, which have been registered under the Securities Act, for each $1,000 principal amount of unregistered 9% Senior Secured Notes due 2011 that were issued in the original issuance.
		In order to be exchanged, an old note must be validly tendered and accepted. All old notes that are validly tendered and not validly withdrawn before the time of expiration will be accepted and exchanged.
		As of this date, there are $165.0 million aggregate principal amount of old notes outstanding.
		We will issue the registered notes promptly after the time of expiration.

Resales of the Registered Notes	Except as described below, we believe that the registered notes to be issued in the exchange offer may be offered for resale, resold and otherwise transferred by you without compliance with the registration and (except with respect to broker-dealers) prospectus delivery provisions of the Securities Act if (but only if) you meet the following conditions:
	•	you are not an "affiliate" of us, as that term is defined in Rule 405 under the Securities Act.
	•	if you are a broker-dealer, you acquired the old notes which you seek to exchange for registered notes as a result of market making or other trading activities and not directly from us and you comply with the prospectus delivery requirements of the Securities Act;
	•	the registered notes are acquired by you in the ordinary course of your business;
	•	you are not engaging in and do not intend to engage in a distribution of the registered notes; and
	•	you do not have an arrangement or understanding with any person to participate in the distribution of the registered notes.
	Our belief is based on interpretations by the staff of the Securities and Exchange Commission (the "SEC"), as set forth in no-action letters issued to third parties unrelated to us. The staff has not considered the exchange offer in the context of a no-action letter, and we cannot assure you that the staff would make a similar determination with respect to the exchange offer.
	If you do not meet the above conditions, you may not participate in the exchange offer or sell, transfer or otherwise dispose of any old notes unless (i) they have been registered for resale by you under the Securities Act and you deliver a "resale" prospectus meeting the requirements of the Securities Act or (ii) you sell, transfer or otherwise dispose of the registered notes in accordance with an applicable exemption from the registration requirements of the Securities Act.
	Any broker-dealer that acquired old notes as a result of market-making activities or other trading activities, and receives registered notes for its own account in exchange for old notes, must acknowledge that it will deliver a prospectus in connection with any resale of the registered notes. See "Plan of Distribution." A broker-dealer may use this prospectus for an offer to resell or to otherwise transfer those registered notes for a period of 180 days after the time of expiration.

Time of Expiration	The exchange offer will expire at 5:00 p.m., New York City time, on , 2005, unless we decide to extend the exchange offer. We do not intend to extend the exchange offer, although we reserve the right to do so.
Conditions to the Exchange Offer	The only conditions to completing the exchange offer are that the exchange offer not violate any applicable law, regulation or applicable interpretation of the staff of the SEC and that no injunction, order or decree of any court or any governmental agency that would prohibit, prevent or otherwise materially impair our ability to proceed with the exchange offer shall be in effect. See "The Exchange Offer—Conditions."
Procedures for Tendering Old Notes Held in the Form of Book-Entry Interests	The old notes were issued as global notes in fully registered form. Beneficial interests in the old notes held by direct or indirect participants in The Depository Trust Company, or DTC, are shown on, and transfers of those interests are effected only through, records maintained in book-entry form by DTC with respect to its participants.
	If you hold old notes in the form of book-entry interests and you wish to tender your old notes for exchange pursuant to the exchange offer, you must transmit to the exchange agent on or prior to the time of expiration of the exchange offer either:
	•	a written or facsimile copy of a properly completed and duly executed letter of transmittal, including all other documents required by such letter of transmittal, at the address set forth on the cover page of the letter of transmittal; or
	•	a computer-generated message transmitted by means of DTC's Automated Tender Offer Program system and received by the exchange agent and forming a part of a confirmation of book-entry transfer, in which you acknowledge and agree to be bound by the terms of the letter of transmittal.
	The exchange agent must also receive on or prior to the expiration of the exchange offer either:
	•	a timely confirmation of book-entry transfer of your old notes into the exchange agent's account at DTC pursuant to the procedure for book-entry transfers described in this prospectus under the heading "The Exchange Offer—Book-Entry Transfer;" or
	•	the documents necessary for compliance with the guaranteed delivery procedures described below.

	A letter of transmittal for your notes accompanies this prospectus. By executing the letter of transmittal or delivering a computer-generated message through DTC's Automated Tender Offer Program system, you will represent to us that, among other things:
	•	you are not an affiliate of us;
	•	you are not a broker-dealer who acquired the old notes that you are sending to the issuer directly from the issuer;
	•	the registered notes to be acquired by you in the exchange offer are being acquired in the ordinary course of your business;
	•	you are not engaging in and do not intend to engage in a distribution of the registered notes; and
	•	you do not have an arrangement or understanding with any person to participate in the distribution of the registered notes.
Procedures for Tendering Certificated Old Notes	If you are a holder of book-entry interests in the old notes, you are entitled to receive, in limited circumstances, in exchange for your book-entry interests, certificated notes which are in equal principal amounts to your book-entry interests. See "Description of Notes—Exchanges of Book-Entry Notes for Certificated Notes." If you acquire certificated old notes prior to the expiration of the exchange offer, you must tender your certificated old notes in accordance with the procedures described in this prospectus under the heading "The Exchange Offer—Procedures for Tendering—Certificated Old Notes."
Special Procedures for Beneficial Owners	If you are the beneficial owner of old notes and they are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and you wish to tender your old notes, you should contact the registered holder promptly and instruct the registered holder to tender on your behalf. If you wish to tender on your own behalf, you must, prior to completing and executing the letter of transmittal and delivering your old notes, either make appropriate arrangements to register ownership of the old notes in your name or obtain a properly completed bond power from the registered holder. The transfer of registered ownership may take considerable time. See "The Exchange Offer—Procedures for Tendering—Procedures Applicable to All Holders."
Guaranteed Delivery Procedures	If you wish to tender your old notes in the exchange offer and:
	(1)	they are not immediately available;

	(2)	time will not permit your old notes or other required documents to reach the exchange agent before the expiration of the exchange offer; or
	(3)	you cannot complete the procedure for book-entry transfer on a timely basis,
	you may tender your old notes in accordance with the guaranteed delivery procedures set forth in "The Exchange Offer—Procedures for Tendering—Guaranteed Delivery Procedures."
Acceptance of Old Notes and Delivery of Registered Notes	Except under the circumstances described above under "The Exchange Offer—Conditions," the issuer will accept for exchange any and all old notes which are properly tendered prior to the time of expiration. The registered notes to be issued to you in the exchange offer will be delivered promptly following the time of expiration. See "The Exchange Offer—Terms of the Exchange Offer."
Withdrawal	You may withdraw the tender of your old notes at any time prior to the time of expiration. We will return to you any old notes not accepted for exchange for any reason without expense to you as promptly after withdrawal, rejection of tender or termination of the exchange offer.
Exchange Agent	The Bank of New York Trust Company, N.A. is serving as the exchange agent in connection with the exchange offer.
Consequences of Failure to Exchange	If you do not participate in the exchange offer for your old notes, upon completion of the exchange offer, the liquidity of the market for your old notes could be adversely affected. See "The Exchange Offer—Consequences of Failure to Exchange."
United States Federal Income Tax Consequences of the Exchange Offer	The exchange of old notes for registered notes in the exchange offer will not be a taxable event for United States federal income tax purposes. See "United States Federal Income Tax Consequences."

Risk Factors

Investing in the registered notes involves substantial risk. See the "Risk Factors" section of this prospectus for a description of certain of the risks you should consider before investing in the notes.

RISK FACTORS

Participating in the exchange offer and investing in the registered notes involves a high degree of risk. You should read and consider carefully each of the following factors, as well as the other information contained in this prospectus, before making a decision on whether to participate in the exchange offer. The risks described below may not be the only ones we face. Additional risks and uncertainties not currently known to us or those we currently deem to be immaterial may also materially and adversely affect our business operations. Any of the following risks could materially adversely affect our business, financial condition or results of operations. In such case, you may lose all or part of your original investment.

Risks Associated with the Exchange Offer

Because there is no public market for the registered notes, you may not be able to resell your registered notes.

The registered notes will be registered under the Securities Act, but will constitute a new issue of securities with no established trading market, and there can be no assurance as to:

•: the liquidity of any trading market that may develop;
•: the ability of holders to sell their registered notes; or
•: the price at which the holders would be able to sell their registered notes.

If a trading market were to develop, the registered notes might trade at higher or lower prices than their principal amount or purchase price, depending on many factors, including prevailing interest rates, the market for similar debentures and our financial performance.

We understand that the initial purchasers of the old notes presently intend to make a market in the notes. However, they are not obligated to do so, and any market-making activity with respect to the notes may be discontinued at any time without notice. In addition, any market-making activity will be subject to the limits imposed by the Securities Act and the Exchange Act, and may be limited during the exchange offer or the pendency of an applicable shelf registration statement. An active trading market may not exist for the registered notes, and any trading market that does develop may not be liquid.

In addition, any holder who tenders in the exchange offer for the purpose of participating in a distribution of the registered notes may be deemed to have received restricted securities, and if so, will be required to comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction. For a description of these requirements, see "The Exchange Offer."

Your old notes will not be accepted for exchange if you fail to follow the exchange offer procedures and, as a result, your old notes will continue to be subject to existing transfer restrictions and you may not be able to sell your old notes.

We will not accept your old notes for exchange if you do not follow the exchange offer procedures. We will issue registered notes as part of this exchange offer only after a timely receipt of your old notes, a properly completed and duly executed letter of transmittal and all other required documents. Therefore, if you wish to tender your old notes, please allow sufficient time to ensure timely delivery. If we do not receive your old notes, letter of transmittal and other required documents by the time of expiration of the exchange offer, we will not accept your old notes for exchange. We are under no duty to give notification of defects or irregularities with respect to the tenders of outstanding old notes for exchange. If there are defects or irregularities with respect to your tender of old notes, we will not accept your old notes for exchange.

If you fail to exchange your old notes, they will continue to be restricted securities and may become less liquid.

Following the exchange offer, old notes that you do not tender or that we do not accept will continue to be restricted securities. You may not offer or sell untendered old notes except pursuant to an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. We will issue registered notes in exchange for the old notes pursuant to the exchange offer only following the satisfaction of the procedures and conditions described elsewhere in this prospectus. These procedures and conditions include timely receipt by the exchange agent of the old notes and of a properly completed and duly executed letter of transmittal. Because we anticipate that most holders of old notes will elect to exchange their old notes, we expect that the liquidity of the market for any old notes remaining after the completion of the exchange offer will be substantially limited.

Risks Related to the Registered Notes

Our substantial level of indebtedness could adversely affect our financial condition and prevent us from fulfilling our obligations on the registered notes.

As of April 1, 2005, we had approximately $170.4 million of indebtedness (including borrowings under our senior revolving credit facility and capital leases). We also have the ability to borrow up to an additional $23.2 million under our senior revolving credit facility. Subject to restrictions in the indenture governing the registered notes and our senior revolving credit facility, we may incur additional indebtedness.

Our high level of indebtedness could have important consequences to you and significant adverse effects on our business, including the following:

•: our ability to obtain additional financing for working capital, capital expenditures, acquisitions or general corporate purposes may be impaired;
•: we must use a substantial portion of our cash flow from operations to pay interest on the registered notes and our other indebtedness, which will reduce the funds available to us for operations and other purposes;
•: any and all of the indebtedness outstanding under our credit facility will have a prior ranking claim on substantially all of our assets and all of the indebtedness outstanding under our purchase money indebtedness, equipment financing and real estate mortgages will have a prior ranking claim on the underlying assets;
•: our ability to fund a change of control offer may be limited;
•: our high level of indebtedness could place us at a competitive disadvantage compared to our competitors that may have proportionately less debt;
•: our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate may be limited; and
•: our high level of indebtedness makes us more vulnerable to economic downturns and adverse developments in our business.

We expect to use cash flow from operations to pay our expenses and amounts due under outstanding indebtedness, including the registered notes. Our ability to make these payments depends on our future performance, which will be affected by financial, business, economic and other factors, many of which we cannot control. Our business may not generate sufficient cash flow from operations in the future and our anticipated growth in revenue and cash flow may not be realized, either or both of which could result in our being unable to repay indebtedness, including the registered notes, or to fund other liquidity needs. If we do not have enough money, we may be required to refinance all or part of our then-existing debt (including the registered notes), sell assets or borrow more money. We

cannot assure you that we will be able to accomplish any of these alternatives on terms acceptable to us, or at all. In addition, the terms of existing or future debt agreements, including our senior revolving credit facility and the indenture, may restrict us from adopting any of these alternatives. The failure to generate sufficient cash flow or to achieve any of these alternatives could significantly adversely affect the value of the registered notes and our ability to pay the amounts due under the registered notes.

Our senior revolving credit facility and the indenture governing the registered notes impose significant operating and financial restrictions, which may prevent us from pursuing certain business opportunities and taking certain actions.

Our senior revolving credit facility and the indenture governing the registered notes impose significant operating and financial restrictions on us. These restrictions limit or prohibit, among other things, our ability to:

•: incur additional indebtedness;
•: repay subordinated indebtedness prior to stated maturities;
•: pay dividends on or redeem or repurchase our 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.

Our senior revolving credit facility also requires us to comply with customary financial covenants including, a minimum fixed charge coverage ratio (when and if the available borrowing capacity is less than $12.5 million) and a maximum annual limit on capital expenditures.

These financial covenants may become more restrictive over time.

A breach of any of these covenants or the inability to comply with the required financial ratios could result in a default under our senior revolving credit facility or the registered notes. If any such default occurs, the lenders under our senior revolving credit facility and the holders of the registered notes may elect to declare all outstanding borrowings, together with accrued interest and other amounts payable thereunder, to be immediately due and payable. The lenders under our senior revolving credit facility also have the right in these circumstances to terminate any commitments they have to provide further borrowings. In addition, following an event of default under our senior revolving credit facility, the lenders under the facility will have the right to proceed against the collateral granted to them to secure the debt. If the debt under our senior revolving credit facility or the registered notes were to be accelerated, we cannot assure you that our assets would be sufficient to repay in full the registered notes and our other debt.

The proceeds from the collateral securing the registered notes may not be sufficient to pay all amounts owed under the registered notes if an event of default occurs and your right to receive payments under the registered notes will be effectively subordinated to our senior revolving credit facility, purchase money indebtedness, capital lease obligations, secured acquired indebtedness and other secured indebtedness to the extent of the value of the assets securing that indebtedness.

No appraisal of the value of the collateral has been made in connection with this offering and the value of the collateral in the event of liquidation will depend on market and economic conditions, the availability of buyers and other factors. Consequently, we cannot assure you that liquidating the collateral securing the registered notes would produce proceeds in an amount sufficient to pay any amounts due under the registered notes after also satisfying the obligations to pay any other senior secured creditors, including the lenders under our senior revolving credit facility. Nor can we assure you that the fair market value of the collateral securing the registered notes would be sufficient to pay any amounts due under the registered notes following their acceleration.

The registered notes and guarantees will be effectively subordinated to indebtedness that may be incurred under our senior revolving credit facility, under which we have borrowing capacity of $30.0 million, any equipment financing, purchase money debt, capital lease obligations, secured acquired indebtedness and other secured indebtedness, in each case, to the extent of the value of the assets securing that indebtedness. Our senior revolving credit facility will be secured by a first priority lien on substantially all of the collateral securing the registered notes. As a result, upon any distribution to our creditors or the creditors of any subsidiary guarantors in bankruptcy, liquidation, reorganization or similar proceedings, or following acceleration of our indebtedness or an event of default under our indebtedness, our lenders under our senior revolving credit facility, our equipment financing, our purchase money indebtedness, our secured acquired indebtedness and other secured indebtedness will be entitled to be repaid in full from the proceeds of the assets securing such indebtedness, or the sale of the equipment subject to the equipment financing, before any payment is made to you from such proceeds.

The rights of the holders of the registered notes with respect to the collateral securing the registered notes will be limited pursuant to the terms of an intercreditor agreement with the lenders under our senior revolving credit facility. Under the intercreditor agreement, if our senior revolving credit facility or our obligations thereunder are outstanding, any actions that may be taken in respect of collateral, including the ability to cause the commencement of enforcement proceedings against the collateral and to control the conduct of such proceedings, and the approval of amendments to the collateral documents, will be limited and, in certain cases, only be able to be taken at the direction of the lenders under such senior revolving credit facility, and the trustee, on behalf of the holders of the registered notes, will not have the ability to control or direct such actions, even if the rights of the holders of the registered notes are or may be adversely affected. Additional releases of collateral from liens securing the registered notes are permitted under some circumstances. See "Description of the Notes—Collateral" and "Description of the Notes—Modification of the Indenture."

A court could avoid the guarantees under fraudulent conveyance laws or certain other circumstances.

If any subsidiary guarantor becomes a debtor in a case under the Bankruptcy Code or encounters other financial difficulty, then under federal or state fraudulent conveyance laws a court in the relevant jurisdiction might avoid or cancel such subsidiary guarantor's guarantee of the registered notes. The court might do so if it found that, when such subsidiary guarantor provided its guarantee, it received less than reasonably equivalent value or fair consideration for such guarantee and either:

•: was insolvent or was rendered insolvent by reason of such guarantee;
•: was engaged, or about to engage, in a business or transaction for which its assets constituted unreasonably small capital;

•: intended to incur, or believed that it would incur, debts beyond its ability to pay such debts as they matured (as all of the foregoing terms are defined in or interpreted under the fraudulent transfer or conveyance statutes); or
•: was a defendant in an action for money damages, or had a judgment for money damages docketed against it (if, in either case, after final judgment the judgment is unsatisfied).

The court might also avoid a guarantee, without regard to the above factors, if it found that the guarantor provided its guarantee with actual intent to hinder, delay or defraud its current or future creditors.

In the United States, a court likely would find that a subsidiary guarantor did not receive reasonably equivalent value or fair consideration in exchange for its guarantee if the value received by such guarantor were found to be disproportionately small when compared with its obligations under such guarantee or, put differently, it did not benefit, directly or indirectly, from the issuance of the registered notes. If a court avoided a guarantee, you would no longer have a claim against the guarantor or against any of its assets securing the guarantee. In addition, the court might direct you to repay any amounts already received from the guarantor or from the proceeds of a foreclosure on any of its assets. If the court were to avoid any guarantee, we cannot assure you that funds would be available to pay the registered notes from another subsidiary guarantor or from any other source.

Each guarantee will state that the liability of each subsidiary guarantor thereunder is limited to the maximum amount that the subsidiary guarantor can incur without risk that the guarantee will be subject to avoidance as a fraudulent conveyance. This limitation may not protect the guarantees from a fraudulent conveyance attack or, if it does, ensure that the guarantees will be in amounts sufficient, if necessary, to pay obligations under the registered notes when due.

The notes will be structurally subordinated to all obligations of our non-guarantor subsidiaries.

The subsidiary guarantors of the registered notes include only our domestic restricted subsidiaries. The registered notes will not be guaranteed by our foreign subsidiaries. As a result of this structure, the registered notes will be structurally subordinated to all indebtedness and other obligations, including trade payables, of our non-guarantor subsidiaries. The effect of this subordination is that, in the event of a bankruptcy, liquidation, dissolution, reorganization or similar proceeding involving a non-guarantor subsidiary, the assets of that subsidiary cannot be used to pay you until after all other claims against that subsidiary, including trade payables, have been fully paid. In addition, holders of minority equity interests in non-guarantor subsidiaries may receive distributions prior to or pro rata with us depending on the terms of the equity interests.

The historical financial data and the pro forma financial data included in this prospectus include our non-guarantor subsidiaries. During 2004, the net sales of our non-guarantor subsidiaries (Altra and PTH, on a combined basis) were $79.3 million, representing approximately 26.1% of total sales, on a combined basis. As of December 31, 2004, the aggregate total assets (based on book value) of our non-guarantor subsidiaries were $49.0 million, representing approximately 16.7% of total assets.

We may not be able to satisfy our obligations to holders of the registered notes upon a change of control.

Upon the occurrence of a change of control, as defined in the indenture, we will be required to offer to purchase the notes at a price equal to 101% of the principal amount thereof, together with any accrued and unpaid interest and liquidated damages, if any, to the date of purchase. See "Description of the Notes—Repurchase upon Change of Control."

We cannot assure you that, if a change of control offer is made, we will have available funds sufficient to pay the change of control purchase price for any or all of the notes that might be delivered by holders of the notes seeking to accept the change of control offer. If we are required to

purchase notes pursuant to a change of control offer, we would be required to seek third-party financing to the extent we do not have available funds to meet our purchase obligations. There can be no assurance that we will be able to obtain such financing on acceptable terms to us or at all. Accordingly, none of the holders of the notes may receive the change of control purchase price for their notes. Our failure to make or consummate the change of control offer or pay the change of control purchase price when due will give the holders of the notes the rights described in "Description of the Notes—Events of Default."

In addition, the events that constitute a change of control under the indenture may also be events of default under our senior revolving credit facility. These events may permit the lenders under our senior revolving credit facility to accelerate the debt outstanding thereunder and, if such debt is not paid, to enforce security interests in our specified assets, thereby limiting our ability to raise cash to purchase the notes and reducing the practical benefit of the offer to purchase provisions to the holders of the notes.

You will face risks related to our holding company structure.

We are a holding company and conduct all of our operations through our subsidiaries. We currently have no significant operating assets other than our direct and indirect investments in our operating subsidiaries. All of our operating income is generated by our operating subsidiaries. We must rely on dividends and other advances and transfers of funds from our subsidiaries and earnings from our investments in cash and marketable securities to provide the funds necessary to meet our debt service obligations, including payment of principal and interest on the notes. Although we are the sole or majority stockholder of each of our operating subsidiaries and therefore able to control their respective declarations of dividends, applicable laws may prevent our operating subsidiaries from being able to pay such dividends. In addition, such payments may be restricted by claims against our subsidiaries by their creditors, such as suppliers, vendors, lessors and employees, and by any applicable bankruptcy, reorganization or similar laws applicable to our operating subsidiaries. The availability of funds and therefore the ability of our operating subsidiaries to pay dividends or make other payments or advances to us, will depend upon their operating results.

Our only significant assets are our investments in the capital stock and ownership interests of our operating subsidiaries, which stock and ownership interests will be pledged as collateral under our senior revolving credit facility. In the event we are unable to pay principal or interest on the notes, the ability of the holders of the notes to proceed against the capital stock or ownership interests of our operating subsidiaries would be subject to the prior satisfaction in full of all amounts owing under our senior revolving credit facility.

Risks Related to Our Business

We operate in the highly competitive mechanical power transmission industry.

We operate in highly fragmented and very competitive markets in the mechanical power transmission industry. As a result, we compete against numerous businesses. 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 and have greater financial and other resources than we do. In particular, we compete with Emerson Power Transmission Manufacturing, L.P., Ogura Industrial Corporation, Regal-Beloit Corporation and Rockwell Automation, Inc. 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. We cannot assure you that we will have sufficient resources to continue to make such investments or that we will maintain our competitive position within each of the markets we serve.

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 adversely affected.

Our business is impacted by general economic conditions and we serve customers in cyclical industries.

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 that we serve are highly cyclical, such as the metals, mining and energy. We have experienced a downturn and a reduction in sales and margins as a result of recent recessionary conditions. While we have undertaken restructuring and cost reduction programs to mitigate the effect of these conditions, we may be unsuccessful in doing so in the future and such actions may be insufficient. 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 may have difficulty predicting future operating results due to both internal and external factors affecting our business and operations.

Our operating results may vary significantly in the future depending on a number of factors, many of which are out of our control, including:

•: the size, timing, cancellation or rescheduling of significant orders;
•: product configuration, mix, performance and quality issues;
•: market acceptance of our new products and product enhancements and new product announcements or introductions by our competitors;
•: manufacturing costs;
•: changes in the cost of raw materials;
•: changes in pricing by us or our competitors;
•: federal exchange rates related to our international operations;
•: seasonality related primarily to the turf and garden market;
•: our ability to develop, introduce and market new products and product enhancements on a timely basis;
•: our success in maintaining brand awareness and in expanding our sales and marketing programs;

•: the loss of any of our intellectual property rights or third-party infringement or misappropriation of our intellectual property rights;
•: the level of competition;
•: potential reductions in inventories held by channel partners;
•: slowing sales of the products of our channel partners;
•: levels of expenditures on research, engineering and product development;
•: changes in our business strategies;
•: personnel changes; and
•: general economic trends and other factors.

We rely on independent distributors.

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 industrial distributors are active participants in the overall competitive dynamics in the mechanical power transmission industry. During 2004, approximately 37.2% of our net sales (Altra and PTH on a combined basis) were generated through industrial distributors. In particular, sales through our largest distributor accounted for approximately 9.0% of our net sales for 2004. 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 cancelable by the distributor after a short notice period. The loss of a substantial number of these distributors or an increase in the distributors' sales of our competitors' products to our customers could materially reduce our sales and profits.

We are subject to risks associated with changing technology and manufacturing techniques, which could place us at a competitive disadvantage.

The successful implementation of our business strategy requires us to continuously evolve our existing products and introduce new products to meet 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 mechanical power transmission products.

Our products are characterized by performance and specification requirements that mandate a high degree of manufacturing and engineering expertise. If we fail 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;
•: price competitiveness;
•: technical expertise and development capability;
•: reliability and timeliness of delivery;
•: product design capability;
•: manufacturing expertise;

•: sales support and customer service; and
•: overall management.

Our success will depend on our ability to continue to meet our customers' changing demands with respect to these criteria. We cannot assure you that we will be able to address technological advances or introduce new products that may be necessary to remain competitive within our markets. Furthermore, we cannot assure you that any of our own technological developments will produce a sustainable competitive advantage.

Our international operations are subject to uncertainties that could affect our operating results.

Our business is subject to certain risks associated with doing business internationally. Our net sales outside North America represented approximately 24.0% of our total net sales for 2004 (Altra and PTH, on a combined basis). Accordingly, our future results could be harmed by a variety of factors, including:

•: fluctuations in currency exchange rates;
•: exchange controls;
•: compliance with U.S. Department of Commerce export controls;
•: tariffs or other trade protection measures and import or export licensing requirements;
•: potentially negative consequences from changes in tax laws;
•: interest rates;
•: unexpected changes in regulatory requirements;
•: a change 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 these jurisdictions;
•: potential political instability and the actions of foreign governments;
•: restrictions on our ability to repatriate dividends from our subsidiaries; and
•: exposure to liabilities under the Foreign Corrupt Practices Act.

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 adversely affect our international operations and, consequently, our operating results.

Material weaknesses in our internal controls over financial reporting have been identified which could result in a decrease in the value of our bonds.

In connection with the audit of our financial statements for 2004, management and our independent registered public accounting firm identified a material weakness in our system of internal controls. This matter is discussed in additional detail under "Management's Discussion and Analysis of Financial Condition and Results of Operations—The Sarbanes-Oxley Act of 2002 and Material Weakness in Internal Controls." In response to the foregoing, we have undertaken a rigorous review of our internal control over financial reporting, that is ongoing, in order to improve our internal controls and ensure the delivery of accurate and timely financial information. We are currently implementing a number of measures intended to meet the foregoing objectives with respect to internal controls and delivery of financial information, and we will need to make significant improvements in our internal controls on an ongoing basis to accomplish these objectives.

We cannot assure you that our ongoing review will not identify additional control deficiencies or that we will be able to implement improvements to our internal controls in a timely manner. In addition, as a result of these reviews or otherwise, we cannot assure you that we will not need to make adjustments to any current period operating results or to operating results that have been previously publicly announced or otherwise experience an adverse affect on our operating results, financial condition or business. Any of the foregoing could result in an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements, which could cause the market price of the notes to decline.

If we are unable to complete our assessment as to the adequacy of our internal controls over financial reporting as of December 31, 2006 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 our bonds.

As directed by Section 404 of the Sarbanes-Oxley Act of 2002, the Securities and Exchange Commission adopted rules requiring public companies to include in their annual reports on Form 10-K a report of management on the company's internal control over financial reporting, including management's assessment of the effectiveness of the company's internal control over financial reporting as of the company's 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 control 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, 2006 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. 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 accounting firm 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 the company's internal controls. It is possible that material weaknesses in our internal controls could be found. If we are unable to remediate such material weaknesses arising by December 31, 2006, our accounting firm would be required to issue an adverse opinion on our internal controls. If our accounting firm disclaims 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 bonds to decline.

Because we sell our products on a purchase order basis and rely on estimated forecasts of our OEM customers' needs, inaccurate forecasts could adversely affect our business.

We generally sell our products pursuant to individual purchase orders instead of 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' product needs. We cannot provide assurance as to the quantities or timing required by our customers for our products. 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, 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 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. If we are unable to pass on materials price increases to our customers, our future profitability may be materially adversely affected.

Restructuring programs initiated in 2002 and 2003 caused disruption in our business and our relationships with our customers.

Colfax Corporation, the previous owner of our business, implemented significant corporate restructurings in 2002 and 2003. These restructurings resulted in certain targeted plant closures, employee reductions and the reorganization of our sales and marketing resources. These restructurings caused disruptions in our business and in our ability to effectively manage our inventory, fulfillment capabilities and customer relationships. If we are unable to restore inventory procedures, retain significant customers or effectively deploy sales and marketing resources, our results will be less than we anticipate.

We could face potential product liability claims relating to products we manufacture or distribute.

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 maintain product liability insurance coverage, but we cannot assure you that we will be able to obtain such insurance on acceptable terms in the future, if at all, or that any such insurance 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 prospects or our ability to make payments on the notes when due. In addition, our business depends on the strong brand reputation we have developed. In the event that this 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 the profitability of our business.

As of April 1, 2005, we had approximately 2,200 employees, of whom approximately 18% were employed abroad, primarily in Europe where trade union membership is common. Approximately 285 of our North American employees are also represented by labor unions. The four U.S. collective bargaining agreements to which we are a party will expire on June 6, 2005, August 10, 2007, September 20, 2007 and February 3, 2008, respectively. Two of the four 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. Although we believe that our current relations with our employees are good, if our unionized workers were to engage in a strike, work stoppage or other slowdown in the future, we could experience a significant disruption of our operations. Such a 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.

Changes in employment laws may adversely affect our business.

Various federal, state and international labor laws govern the relationship with our employees and affect operating costs. These laws include minimum wage requirements, overtime, unemployment tax rates, workers' compensation rates and citizenship requirements. Significant additional government-imposed increases in the following areas could materially affect our business, financial condition, operating results or cash flow:

•: minimum wages;
•: mandated health benefits;
•: paid leaves of absence; and
•: tax reporting.

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 process. Any interruption in our manufacturing process would interrupt our production of products, reduce our income and cash flow and could result in a material adverse effect on 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, 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 severance agreements with certain of our key domestic executives, we can not prevent our key executives from terminating their employment with us. We do not maintain key person life insurance policies on any of our executives. See "Management."

We face risks associated with environmental laws.

We are subject to extensive foreign, provincial, federal, state and local laws, regulations and ordinances that:

•: regulate activities and operations that may have environmental or health and safety effects, such as discharges to air and water, and management and disposal practices for solid and hazardous wastes; and
•: impose liability for the costs of investigating and cleaning up, and damages to natural resources from, past spills, waste disposals on and off-site, or other releases of hazardous materials or regulated substances.

In particular, under applicable environmental laws, we may be responsible for the investigation and remediation of environmental conditions at currently owned or leased sites, as well as formerly owned, leased, operated or used sites. We may be subject to associated liabilities, including liabilities resulting from lawsuits brought by private litigants, relating to the operations of our facilities or the land on which our facilities are located, regardless of whether we lease or own the facility, and regardless of whether such environmental conditions were created by us or by a prior owner or tenant, or by a third-party or a neighboring facility whose operations may have affected our facility or land. This is because liability for contamination under certain environmental laws can be imposed on the current or past owners or operators of a site without regard to fault. Moreover, our operations generated hazardous wastes that are disposed of or treated at third-party owned or operated disposal sites. If those sites become contaminated, we could also be held responsible for the cost of investigating and remediating those sites. We cannot assure you that environmental conditions relating to our prior, existing or future sites or those of predecessor companies whose liabilities we may have assumed or acquired will not have a material adverse affect on our business.

We face risks associated with our post-retirement and post-employment obligations to employees.

As part of the Acquisition, we agreed to assume pension plan liabilities for active U.S. employees under the Retirement Plan for Power Transmission Employees of Colfax Corporation, 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 IRC, such assets and liabilities relating to active U.S. employees as of the closing of the Acquisition. Given the funded status of the Prior Plans and the asset allocation requirements of IRC Section 414(l), liabilities under the New Plan will greatly exceed the assets that will be transferred from the Prior Plans. Pension benefit liabilities for the New Plan, on a projected benefits obligation basis (assuming the liability for vested and unvested pension benefits accrued as of a particular date), were approximately $21.5 million as of December 31, 2004 while the fair value of assets transferred from the Prior Plans were approximately $4.6 million. As the New Plan will have a considerable funding deficit, the cash funding requirements are estimated to be substantial in the first several years, and could have a material adverse effect on our financial condition. Funding requirements are $0.5 million in 2005 and are estimated to be at least $7.4 million in 2006, declining to approximately $2.2 million in 2009.

Additionally, as part of the Acquisition, we agreed to assume all pension plan liabilities related to non-U.S. employees. Pension benefit liabilities for the non-U.S. defined benefit plans, on a projected benefits obligation basis, were approximately $3.2 million as of December 31, 2004. There are no assets associated with these plans.

Also as part of the Acquisition, we agreed to assume all post-employment and post-retirement welfare benefit obligations with respect to active U.S. employees. The benefit obligation for these liabilities, which are not funded, was approximately $12.6 million as of December 31, 2004.

Our future success depends on our ability to effectively integrate acquired companies and manage our growth.

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. The integration of the companies will demand 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 cannot assure you that we will be able to integrate successfully our recent acquisitions or any future acquisitions, that these acquired companies will operate profitably, or that we will realize the potential benefits from these acquisitions.

Our ability to grow may be adversely impacted by an inability to identify acquisition candidates.

A substantial portion of the growth in our business has come through acquisitions and an important part of our growth strategy is based upon future acquisitions. We may not be able to identify and successfully negotiate suitable acquisitions, obtain financing for future acquisitions on satisfactory terms or otherwise complete acquisitions in the future. If we are unable to successfully complete acquisitions, our ability to significantly grow our company will be limited.

We may not be able to protect our intellectual property rights, brands or technology effectively.

We rely on a combination of patent, trademark, domain name registration, copyright and trade secret laws in the United States and other jurisdictions, as well as license, third-party nondisclosure, employee and consultant assignment and other agreements in order to protect our proprietary technology and rights. We cannot assure you that any of our applications for protection of our intellectual property rights will be approved, that if issued, will be maintained, or that others will not infringe or challenge our intellectual property rights. We also 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 from time to time pursue potential claims 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.

We are a newly formed company with no operating history as a stand-alone company, which may lead to risks or unanticipated expenses similar to those of a start-up company.

Prior to the Acquisition, Colfax Corporation provided PTH with a number of support services, including accounting, treasury, taxation, legal and intellectual property, insurance administration, human resource functions and environmental support. As a stand-alone company following the Acquisition, we will need to establish our own capabilities or replace such services. Although we entered into a transition services agreement pursuant to which Colfax Corporation continued to provide these services for transition periods generally ranging from one month to one year while we establish our own capabilities, we cannot assure you that we will be able to replace the services we historically received from Colfax Corporation in a timely manner or on terms and conditions we will find acceptable. We may need to pay more for the services we historically received from Colfax Corporation in the future.

If we are unable to successfully establish our own capabilities or replace such services on a basis appropriate for operation as a stand-alone company, our business and operations will be adversely affected.

Genstar Capital controls our company and its interests may conflict with yours.

Genstar Capital and its affiliates, through their majority ownership of Holdings, have the indirect power to elect our directors, to appoint members of management and to approve all actions requiring the approval of the holders of our common stock, including adopting amendments to our certificate of incorporation and approving mergers, acquisitions or sales of all or substantially all of our assets.

The interests of Genstar Capital could conflict with your interests. For example, if we encounter financial difficulties or are unable to pay our debts as they mature, the interests of Genstar Capital as our ultimate controlling stockholder might conflict with your interests as a holder of the notes. Genstar Capital also may have an interest in pursuing acquisitions, divestitures, financings or other transactions that, in its judgment, could enhance its equity investment, even though such transactions might involve risks to you as holders of the notes.

DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

We make "forward-looking statements" throughout this prospectus. 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. The forward-looking information contained in this prospectus is generally located under the headings "Prospectus Summary," "Risk Factors," "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Business," but may be found in other locations as well. 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.

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, such as the ability to increase revenues and/or to achieve cost reductions, and other factors discussed under "Risk Factors" or elsewhere in this prospectus, which also would cause actual results to differ from present plans or expectations. Such differences could be material.

You should read this prospectus completely and with the understanding that actual future results may be materially different from what we expect. We will not update these forward-looking statements, even if our situation changes in the future.

THE EXCHANGE OFFER

Purpose and Effect

We issued the old notes on November 30, 2004, in a private placement to a limited number of qualified institutional buyers, as defined under the Securities Act, and to a limited number of persons outside the United States. In connection with this original issuance, we and the subsidiary guarantors entered into an indenture and a registration rights agreement. The registration rights agreement requires that we file a registration statement under the Securities Act with respect to the registered notes to be issued in the exchange offer and, upon the effectiveness of the registration statement, offer to you the opportunity to exchange your old notes for a like principal amount of registered notes. Except as set forth below, these registered notes will be issued without a restrictive legend and we believe, may be reoffered and resold by you without registration under the Securities Act. After we complete the exchange offer, our obligations with respect to the registration of the old notes and the registered notes will terminate, except as provided in the last paragraph of this section. Copies of the indenture relating to the notes and the registration rights agreement have been filed as exhibits to the registration statement on Form S-4 of which this prospectus forms a part.

Based on an interpretation by the staff of the SEC set forth in no-action letters issued to third parties unrelated to us, we believe that the registered notes issued to you in the exchange offer may be offered for resale, resold and otherwise transferred by you, without compliance with the registration and prospectus delivery provisions of the Securities Act, unless you are a broker-dealer that receives registered notes in exchange for old notes acquired by you as a result of market-making or other trading activities. This interpretation, however, is based on your representation to us that:

•: the registered notes to be issued to you in the exchange offer are being acquired in the ordinary course of your business;
•: you are not engaging in and do not intend to engage in a distribution of the registered notes to be issued to you in the exchange offer; and
•: you have no arrangement or understanding with any person to participate in the distribution of the registered notes to be issued to you in the exchange offer.

If you have any of the disqualifications described above or cannot make any of the representations set forth above, you may not rely on this interpretation by the staff of the SEC referred to above. Under those circumstances, you must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a sale, transfer or other disposition of any notes unless you are able to utilize an applicable exemption from all those requirements. Each broker-dealer that receives registered notes for its own account in exchange for old note where such old notes were acquired by such broker-dealer as a result of market-making activities or other trading activities must acknowledge that it will deliver a prospectus in connection with any resale of those registered notes. See "Plan of Distribution."

If you will not receive freely tradeable registered notes in the exchange offer or are not eligible to participate in the exchange offer, you may elect to have your old notes registered in a "shelf" registration statement on an appropriate form pursuant to Rule 415 under the Securities Act. If we are obligated to file a shelf registration statement, we will be required to keep the shelf registration statement effective until the earlier of (a) two years from the date the securities were originally issued, (b) the date on which all the securities registered under the shelf registration statement are disposed in accordance with the shelf registration statement or (c) there ceases to be any old notes outstanding. Other than as set forth in this paragraph, you will not have the right to require us to register your old notes under the Securities Act. See "—Procedures for Tendering."

Consequences of Failure to Exchange

After we complete the exchange offer, if you have not tendered your old notes, you will not have any further registration rights, except as set forth above. Your old notes may continue to be subject to certain restrictions on transfer. Therefore, the liquidity of the market for your old notes could be adversely affected upon completion of the exchange offer if you do not participate in the exchange offer.

Terms of the Exchange Offer

Upon the terms and subject to the conditions set forth in this prospectus and in the letter of transmittal, we will accept any and all old notes validly tendered and not withdrawn prior to the time of expiration. We will issue a principal amount of registered notes in exchange for the principal amount of old notes accepted in the exchange offer. You may tender some or all of your old notes pursuant to the exchange offer. However, old notes may be tendered only in integral multiples of $1,000 principal amount.

The form and terms of the registered notes are substantially the same as the form and terms of the old notes, except that the registered notes to be issued in the exchange offer have been registered under the Securities Act and will not bear legends restricting their transfer. The registered notes will be issued pursuant to, and entitled to the benefits of, the indenture which governs the old notes. The registered notes and old notes will be deemed a single issue of securities under the indenture.

As of the date of this prospectus, $165.0 million aggregate principal amount of old notes was outstanding. This prospectus, together with the letter of transmittal, is being sent to all registered holders and to others believed to have beneficial interests in the old notes. We intend to conduct the exchange offer in accordance with the applicable requirements of the Exchange Act and the rules and regulations of the SEC promulgated under the Exchange Act.

We will be deemed to have accepted validly tendered old notes when, as, and if we have given oral or written notice of its acceptance to the exchange agent. The exchange agent will act as our agent for the tendering holders for the purpose of receiving the registered notes from us. If we do not accept any tendered old notes because of an invalid tender or the failure of any conditions to the exchange offer to be satisfied, we will return the unaccepted old notes, without expense, to the tendering holder as promptly as practicable after the time of expiration. For the conditions of the exchange offer see "—Conditions."

You will not be required to pay brokerage commissions or fees or, except as set forth below under "—Transfer Taxes," transfer taxes with respect to the exchange of your old notes in the exchange offer. We will pay all charges and expenses, other than certain applicable taxes, in connection with the exchange offer. See "—Fees and Expenses" below.

Expiration; Amendments

The exchange offer will expire at 5:00 p.m., New York City time, on, 2005, unless we determine, in our sole discretion, to extend the exchange offer, in which case it will expire at the later date and time to which it is extended. We do not intend to extend the exchange offer, although we reserve the right to do so. If we do extend the exchange offer, we will give oral or written notice of the extension to the exchange agent and give each registered holder of old notes for which the exchange offer is being made notice by means of a press release or other public announcement of any extension prior to 9:00 a.m., New York City time, on the next business day after the scheduled expiration date of the exchange offer.

We also reserve the right, in our sole discretion:

•: to delay accepting any old notes or, if any of the conditions set forth below under "—Conditions" have not been satisfied or waived, to terminate the exchange offer by giving oral or written notice of the delay or termination to the exchange agent; or
•: to amend the terms of the exchange offer in any manner by complying with Rule 14e-1(d) under the Exchange Act of the extent that rule applies.

We acknowledge and undertake to comply with the provisions of Rule 14e-1(c) under the Exchange Act, which requires us to return the old notes surrendered for exchange promptly after the termination or withdrawal of the exchange offer. We will notify you promptly of any extension, termination or amendment.

Procedures for Tendering

Book-Entry Interests

The old notes were issued as global notes in fully registered form. Beneficial interests in the global notes, held by direct or indirect participants in DTC, are shown on, and transfers of these interests are effected only through, records maintained in book-entry form by DTC with respect to its participants.

If you hold old notes in the form of book-entry interests and you wish to tender your old notes for exchange pursuant to the exchange offer, you must transmit to the exchange agent on or prior to the time of expiration either:

•: a written or facsimile copy of a properly completed and duly executed letter of transmittal, including all other documents required by that letter of transmittal, to the exchange agent at the address set forth on the cover page of the letter of transmittal; or
•: a computer-generated message transmitted by means of DTC's Automated Tender Offer Program system and received by the exchange agent and forming a part of a confirmation of book-entry transfer, in which you acknowledge and agree to be bound by the terms of the letter of transmittal.

In addition, in order to deliver old notes held in the form of book-entry interests:

•: a timely confirmation of book-entry transfer of those old notes into the exchange agent's account at DTC pursuant to the procedure for book-entry transfers described below under "—Book-Entry Transfer" must be received by the exchange agent prior to the time of expiration; or
•: you must comply with the guaranteed delivery procedures described below.

The method of delivery of old notes and the letter of transmittal and all other required documents to the exchange agent is at your election and risk. Instead of delivery by mail, we recommend that you use an overnight or hand delivery service. In all cases, sufficient time should be allowed to assure delivery to the exchange agent before the time of expiration. You should not send the letter of transmittal or old notes to us. You may request your broker, dealer, commercial bank, trust company or other nominee to effect the above transactions for you.

Certificated Old Notes

Only registered holders of certificated old notes may tender those notes in the exchange offer. If your old notes are certificated notes and you wish to tender those notes for exchange pursuant to the exchange offer, you must transmit to the exchange agent on or prior to the time of expiration, a written or facsimile copy of a properly completed and duly executed letter of transmittal, including all other

required documents, to the address set forth below under "—Exchange Agent." In addition, in order to validly tender your certificated old notes:

•: the certificates representing your old notes must be received by the exchange agent prior to the time of expiration; or
•: you must comply with the guaranteed delivery procedures described below.

Procedures Applicable to All Holders

If you tender an old note and you do not withdraw the tender prior to the time of expiration, you will have made an agreement with us in accordance with the terms and subject to the conditions set forth in this prospectus and in the letter of transmittal.

If your old notes are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and you wish to tender your old notes, you should contact the registered holder promptly and instruct the registered holder to tender on your behalf. If you wish to tender on your own behalf, you must, prior to completing and executing the letter of transmittal and delivering your old notes, either make appropriate arrangements to register ownership of the old notes in your name or obtain a properly completed bond power from the registered holder. The transfer of registered ownership may take considerable time.

Signatures on a letter of transmittal or a notice of withdrawal must be guaranteed by a financial institution, including most banks, savings and loan associations and brokerage houses, that is a medallion signature guarantor, each an "eligible institution," unless:

•: old notes tendered in the exchange offer are tendered either:
•: by a registered holder who has not completed the box entitled "Special Issuance Instructions" or "Special Delivery Instructions" on the holder's letter of transmittal; or
•: for the account of an eligible institution; and
•: the box entitled "Special Registration Instructions" on the letter of transmittal has not been completed.

If the letter of transmittal is signed by a person other than you, your old notes must be endorsed or accompanied by a properly completed bond power and signed by you as your name appears on those old notes.

If the letter of transmittal or any old notes or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, those persons should so indicate when signing. Unless we waive this requirement, in this instance you must submit with the letter of transmittal proper evidence satisfactory to us of its authority to act on your behalf.

We will determine, in our sole discretion, all questions regarding the validity, form, eligibility, including time of receipt, acceptance and withdrawal of tendered old notes. This determination will be final and binding. We reserve the absolute right to reject any and all old notes not properly tendered or any old notes, our acceptance of which would, in the opinion of our counsel, be unlawful. We also reserve the right to waive any defects, irregularities or conditions of tender as to particular old notes; provided, however, that, in the event we waive any condition of tender for any noteholder, we will waive that condition for all noteholders. Our interpretation of the terms and conditions of the exchange offer, including the instructions in the letter of transmittal, will be final and binding on all parties.

You must cure any defects or irregularities in connection with tenders of your old notes within the time period we determine unless we waive that defect or irregularity. Although we intend to notify you

of defects or irregularities with respect to your tender of old notes, neither we, the exchange agent nor any other person will incur any liability for failure to give this notification. Your tender will not be deemed to have been made and your old notes will be returned to you if:

•: you improperly tender your old notes; or
•: you have not cured any defects or irregularities in your tender; and
•: we have not waived those defects, irregularities or improper tender.

Unless otherwise provided in the letter of transmittal, the exchange agent will return your old notes as soon as practicable following the expiration of the exchange offer.

In addition, we reserve the right, in our sole discretion, to:

•: purchase or make offers for, or offer registered notes for, any old notes that remain outstanding subsequent to the expiration of the exchange offer;
•: terminate the exchange offer upon the failure of any condition to the exchange offer to be satisfied; and
•: to the extent permitted by applicable law, purchase notes in the open market, in privately negotiated transactions or otherwise.

The terms of any of these purchases or offers could differ from the terms of the exchange offer. By tendering in the exchange offer, you will represent to us that, among other things:

•: you are not an "affiliate" of us, as defined in Rule 405 under the Securities Act;
•: if you are a broker-dealer, you acquired the old notes which you seek to exchange for registered notes as a result of market making or other trading activities and not directly from the issuer and you comply with the prospectus delivery requirements of the Securities Act;
•: the registered notes to be issued to you in the exchange offer are being acquired in the ordinary course of your business;
•: you are not engaging in and do not intend to engage in a distribution of the registered notes to be issued to you in the exchange offer; and
•: you do not have an arrangement or understanding with any person to participate in the distribution of the registered notes to be acquired by you in the exchange offer.

In all cases, issuance of registered notes for old notes that are accepted for exchange in the exchange offer will be made only after timely receipt by the exchange agent of certificates for your old notes or a timely book-entry confirmation of your old notes into the exchange agent's account at DTC, a properly completed and duly executed letter of transmittal and all other required documents. If any tendered old notes are not accepted for any reason set forth in the terms and conditions of the exchange offer or if old notes are submitted for a greater principal amount than you desire to exchange, the unaccepted or non-exchanged old notes, or old notes in substitution therefor, will be returned without expense to you. In addition, in the case of old notes, tendered by book-entry transfer into the exchange agent's account at DTC pursuant to the book-entry transfer procedures described below, the non-exchanged old notes will be credited to your account maintained with DTC, as promptly as practicable after the expiration or termination of the exchange offer.

Guaranteed Delivery Procedures

If you desire to tender your old notes and your old notes are not immediately available or one of the situations described in the immediately preceding paragraph occurs, you may tender if:

•: you tender through an eligible institution;
•: on or prior to the time of expiration, the exchange agent receives from an eligible institution, a written or facsimile copy of a properly completed and duly executed letter of transmittal and notice of guaranteed delivery, substantially in the form provided by us; and
•: the certificates for all certificated old notes, in proper form for transfer, or a book-entry confirmation, and all other documents required by the letter of transmittal, are received by the exchange agent within three New York Stock Exchange trading days after the date of execution of the notice of guaranteed delivery.

The notice of guaranteed delivery may be sent by facsimile transmission, mail or hand delivery. The notice of guaranteed delivery must set forth:

•: your name and address;
•: the amount of old notes you are tendering; and
•: a statement that your tender is being made by the notice of guaranteed delivery and that you guarantee that within three New York Stock Exchange trading days after the execution of the notice of guaranteed delivery, the eligible institution will deliver the following documents to the exchange agent:
•: the certificates for all certificated old notes being tendered, in proper form for transfer or a book-entry confirmation of tender;
•: a written or facsimile copy of the letter of transmittal, or a book-entry confirmation instead of the letter of transmittal; and
•: any other documents required by the letter of transmittal.

Book-Entry Transfer

The exchange agent will establish accounts with respect to book-entry interests at DTC for purposes of the exchange offer promptly after the date of this prospectus. You must deliver your book-entry interest by book-entry transfer to the account maintained by the exchange agent at DTC for the exchange offer. Any financial institution that is a participant in DTC's systems may make book-entry delivery of book-entry interests by causing DTC to transfer the book-entry interests into the relevant account of the exchange agent at DTC in accordance with DTC's procedures for transfer.

If you are unable to:

•: deliver a book-entry confirmation of book-entry delivery of your book-entry interests into the relevant account of the exchange agent at DTC; or
•: deliver all other documents required by the letter of transmittal to the exchange agent prior to the time of expiration;

then you must tender your book-entry interests according to the guaranteed delivery procedures discussed above.

Withdrawal Rights

You may withdraw tenders of your old notes at any time prior to the time of expiration.

For your withdrawal to be effective, the exchange agent must receive a written or facsimile transmission notice of withdrawal at its address set forth below under "—Exchange Agent" prior to the time of expiration.

The notice of withdrawal must:

•: state your name;
•: identify the specific old notes to be withdrawn, including the certificate number or numbers and the principal amount of old notes to be withdrawn;
•: be signed by you in the same manner as you signed the letter of transmittal when you tendered your old notes, including any required signature guarantees, or be accompanied by documents of transfer sufficient for the exchange agent to register the transfer of the old notes into your name; and
•: specify the name in which the old notes are to be registered, if different from yours.

We will determine all questions regarding the validity, form and eligibility, including time of receipt, of withdrawal notices. Our determination will be final and binding on all parties. Any withdrawn tenders of old notes will be deemed not to have been validly tendered for exchange for purposes of the exchange offer. Any old notes which have been tendered for exchange but which are not exchanged for any reason will be returned to you without cost as soon as practicable after withdrawal, rejection of tender or termination of the exchange offer. Properly withdrawn old notes may be retendered by following one of the procedures described under "—Procedures for Tendering" above at any time on or prior to the time of expiration.

Conditions

Notwithstanding any other provision of the exchange offer and subject to our obligations under the registration rights agreement, we will not be required to accept for exchange, or to issue registered notes in exchange for, any old notes in the exchange offer and may terminate or amend the exchange offer, if at any time before the acceptance of any old notes for exchange in the exchange offer any of the following events occur:

•: any injunction, order or decree has been issued by any court or any governmental agency that would prohibit, prevent or otherwise materially impair our ability to proceed with the exchange offer; or
•: the exchange offer violates any applicable law, regulation or interpretation of the staff of the SEC.

These conditions are for our sole benefit and we may assert them regardless of the circumstances giving rise to them, subject to applicable law. We also may waive in whole or in part at any time and from time to time any particular condition to the exchange offer in our sole discretion. If we waive a condition, we may be required to extend the expiration of the exchange offer in order to comply with applicable securities laws. Our failure at any time to exercise any of the foregoing rights will not be deemed a waiver of these rights, and these rights will be deemed ongoing rights which may be asserted at any time and from time to time (in the case of any condition involving governmental approvals necessary for the completion of the exchange offer) and at any time prior to the time of expiration (in the case of all other conditions).

In addition, we will not accept for exchange any old notes tendered, and no registered notes will be issued in exchange for any of those old notes, if at the time the old notes are tendered any stop order is threatened by the SEC or in effect with respect to the registration statement of which this

prospectus is a part or the qualification of the indenture under the Trust Indenture Act of 1939, as amended.

The exchange offer is not conditioned on any minimum principal amount of old notes being tendered for exchange.

Transfer Taxes

You will not be obligated to pay any transfer taxes in connection with a tender of your old notes for exchange unless you instruct us to register registered notes in the name of, or request that old notes not tendered or not accepted in the exchange offer be returned to, a person other than the registered tendering holder, in which event, the registered tendering holder will be responsible for the payment of any applicable transfer tax.

Accounting Treatment

We will not recognize any gain or loss for accounting purposes upon the consummation of the exchange offer. We will amortize the expense of the exchange offer and the unamortized expenses related to the issuance of the old notes over the term of the registered notes under accounting principles generally accepted in the United States of America.

UNAUDITED PRO FORMA FINANCIAL STATEMENTS

The following unaudited pro forma financial information has been derived by the combination of and application of pro forma adjustments to the historical financial statements of Kilian for the periods December 28, 2003 through October 22, 2004 and October 23 through November 30, 2004; and of PTH for the period January 1 through November 30, 2004; and of Altra from inception to December 31, 2004. The unaudited pro forma statement of income for the year ended December 31, 2004 gives effect to the Acquisition and Related Transactions as if they had been consummated on January 1, 2004. We have not included an unaudited pro forma balance sheet since the balance sheet, at December 31, 2004, included in this prospectus gives effect to the Acquisition.

Assumptions underlying the pro forma adjustments are described in the accompanying notes, which should be read in conjunction with this unaudited pro forma financial information.

The unaudited pro forma adjustments are based upon available information and certain assumptions that we believe are reasonable under the circumstances. The unaudited pro forma financial information does not purport to represent what the results of operations of Altra would have been had the Acquisition and Related Transactions actually occurred on January 1, 2004, nor do they purport to project the results of operations of Altra for any future period. The unaudited pro forma statement of income should be read in conjunction with the information contained in "Selected Historical Financial Data," "Management's Discussion and Analysis of Financial Condition and Results of Operations" and our financial statements and the related notes thereto appearing elsewhere in this registration statement.

SELECTED HISTORICAL FINANCIAL DATA

We were formed to facilitate the Acquisition and Related Transactions. The following table contains selected historical financial data of Altra for the period from inception (December 1, 2004) to December 31, 2004 and PTH, or the Predecessor, for the period from January 31, 2004 through November 30, 2004 and for the years ended December 31, 2003, 2002 and 2001. Colfax Corporation did not maintain separate financial statements for PTH as a stand-alone business. At the time of the Acquisition, Colfax Corporation produced historical financial statements for PTH for the fiscal years ended December 31, 2001, 2002 and 2003 but was not able to provide us with audited financial statements for PTH for the fiscal year ended December 31, 2000. We do not have access to information for PTH relating to the fiscal year ended December 31, 2000. As a result, historical financial data for the fiscal year ended December 31, 2000 is not available to us and consequently we are unable to disclose selected historical financial data for PTH for the fiscal year ended December 31, 2000. The following should be read in conjunction with "Use of Proceeds," "Capitalization," "Unaudited Pro Forma Financial Statements," "Management's Discussion and Analysis of Financial Condition and Results of Operations" and the consolidated financial statements and notes included elsewhere in this registration statement.

RATIO OF EARNINGS TO FIXED CHARGES

The following table sets forth the ratio of earnings to fixed charges for the period from inception on December 1, through December 31, 2004, the period from January 1 through November 30, 2004 and the years 2003, 2002 and 2001:

⁽²⁾: Earnings were insufficient to cover fixed charges in the period December 1 through December 31, 2004, and each of the years ended December 31, 2003 and 2002 by $1.8 million, $10.5 million and $21.7 million, respectively.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

The following discussion of the financial condition and results of operations of Altra Industrial Motion, Inc. should be read together with the Selected Financial Data, Unaudited Pro Forma Financial Statements and the financial statements of Altra Industrial Motion, Inc. and related notes included elsewhere in this registration statement. 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 "Forward-Looking Statements."

General

Altra is a leading multi-national designer, producer and marketer of a wide range of mechanical power transmission products. Our product portfolio includes industrial clutches and brakes, enclosed gear drives, open gearing, couplings, machined-race bearings and other related products which are sold across a wide variety of industries. Our products benefit from our industry leading brand names including Ameridrives, Boston Gear, Warner Electric, Formsprag Clutch, Industrial Clutch, Kilian, Marland Clutch, Nuttall Gear, Stieber and Wichita Clutch. Our products serve a wide variety of end markets including automotive, general industrial, material handling, mining, power generation, transportation and turf and garden. We primarily sell our products to OEMs such as John Deere, Carrier and General Electric 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.

History and the Acquisitions

Altra and PTH, its Predecessor, have designed and marketed mechanical power transmission products for over a century. Our current business began with the acquisition by Colfax Corporation of the mechanical power transmission group of Zurn Technologies, Inc. in December 1996. Colfax Corporation 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 Corporation's acquisition of Imo Industries, Inc. In February 2000, Colfax Corporation acquired Warner Electric, Inc., which sold products under the Warner Electric, Formsprag Clutch, Stieber and Wichita Clutch brands. The businesses that formed PTH were operated as independent businesses within Colfax Corporation and participated in various strategic initiatives implemented by Colfax Corporation, including lean manufacturing programs.

On November 30, 2004, we acquired PTH and Kilian in the Acquisition described under "The Acquisition and Related Transactions." Although we plan to continue our focus on improved operating efficiency, the programs previously implemented by Colfax Corporation may be modified or terminated after the Acquisition. Because of such modifications or terminations, the results of operations of the Predecessor may not be fully indicative of our results of operations as a stand-alone company. See "Risk Factors—Risks Relating to Our Business—We are a newly formed company with no operating history as a stand-alone company, which may lead to risks or unanticipated expenses similar to those of a start-up company."

Recent Cost Savings and Productivity Enhancement Initiatives

Our Predecessor enacted significant cost savings programs over the last several years to reduce its overall cost structure and improve cash flows. Cost reduction programs included the consolidation of facilities, headcount reductions and reductions in overhead costs, which resulted in restructuring charges, asset impairment and transition expenses of $11.1 million and $27.8 million in the year ending December 31, 2003 and 2002, respectively. Cash outflows related to the restructuring programs were

$2.2 million in 2004, $13.9 million in 2003 and $3.3 million in 2002. The financial impact of some of the specific cost reduction programs implemented by the Predecessor is listed below:

•: In 2002, the Predecessor accrued approximately $7.1 million in restructuring charges, of which $6.7 million represented severance costs related to work force reductions of approximately 315 manufacturing and administrative employees.
•: In 2002, the Predecessor recognized a non-cash impairment charge of approximately $18.1 million relating to the reduced value of certain assets following plant closures.
•: In 2002 and 2003, the Predecessor incurred transition expenses, including relocation, training, recruiting and moving costs, directly related to implementing its restructuring activities amounting to $2.6 million and $9.1 million, respectively.
•: In 2003, the 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.

For a description of restructuring and other similar costs of the Predecessor, refer to Note 14 to the audited financial statements included elsewhere in this registration statement.

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, 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 generally accepted accounting standards. Collection is reasonably assured as determined through an evaluation of each customer's ability to pay.

Inventory. In connection with the Acquisition, we adjusted the fair value of acquired finished goods inventories to their estimated sales price less an appropriate amount representing the expected profitability from selling efforts, in accordance with SFAS No. 141,Business Combinations. The fair value adjustment reduced gross margin by approximately $1.7 million during December 2004, a similar reduction will occur in the first quarter of 2005.

We value raw materials, WIP and finished goods produced since Inception at the lower of cost or market, as determined on a first-in, first-out (FIFO) basis. In some cases, we have determined 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.

Following the Acquisition, we retained the defined benefit plans for active and former employees of our subsidiaries located outside the United States and the pension and other post retirement benefit liabilities associated only with active personnel in the United States. The liabilities associated with pension and post retirement obligations were restated to their fair value in accordance with purchase accounting as prescribed by SFAS No. 141Business Combinations, SFAS No. 87Employers' Accounting for Pensions, and FAS 106Employers' Accounting for Postretirement Benefits Other Than Pensions.

Intangible assets. Intangible assets of the 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 Acquisition, intangible assets were identified and recorded at their fair value, as determined by an independent valuation firm, in accordance with SFAS No. 141,Business Combinations. The Company recorded intangible assets for customer relationships, tradenames and trademarks, product technology and patents, and goodwill. Customer relationships and product technology and patents are considered finite-lived assets, with estimated lives ranging from 8 to 12 years. Goodwill and tradenames and trademarks are considered indefinite lived assets.

As discussed in Note 6 to the audited financial statements, the Predecessor adopted SFAS No. 142Goodwill and Other Intangible Assets and recorded an after-tax impairment charge of $83.4 million during 2002. 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 are in the process of allocating our final goodwill and intangible assets, arising from the application of purchase accounting for the Predecessor and Kilian acquisitions, and have not yet allocated these assets across its business units. We evaluated our intangible assets at the Company level at December 31, 2004 and found no evidence of impairment at that date. Our analysis included consideration of the purchase price paid for the acquisitions on November 30, 2004 and the fair value of our acquired assets as determined by an independent valuation firm.

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.

As a result of the Acquisition, tangible fixed assets were restated to their fair value, as determined by an independent valuation firm, in accordance with SFAS No. 141,Business Combinations.

Income taxes. At the end of each quarter, management estimates the effective tax rate expected to be applicable for the full year. The estimated effective tax rate reflects the expected jurisdiction where income is earned as well as tax planning strategies. If the actual results are different from our estimates, adjustments to the effective tax rate may be required in the period in which such determination is made.

We recognize deferred tax assets and liabilities based on the differences between the financial statement carrying amounts and the tax basis of assets and liabilities. Our management regularly reviews deferred tax assets for recoverability and establishes a valuation allowance based on historical losses, projected future taxable income and the expected timing of the reversals of existing temporary differences. As a result of this review, a valuation allowance has been established against a portion of the deferred tax assets.

Non-GAAP Financial Measures

The discussion of Results of Operations included below includes certain references to financial results on a "combined basis." The combined results were prepared by adding the results of Altra from Inception to December 31, 2004 to those from the Predecessor for the 11 month period ending November 30, 2004. Management believes that this presentation provides useful information for our investors in the comparison of Predecessor trends and operating results. The combined results are not necessarily indicative of what our results of operations may have been if the Acquisition and Related Transactions had been consummated earlier, nor should they be construed as being a representation of our future results of operations.

The discussion of EBITDA (earnings before interest, income taxes, depreciation and amortization) included in the discussion of Results of Operations below is being provided because management considers EBITDA to be an important measure of financial performance. Among other things, management believes that EBITDA provides useful 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 are significantly impacted by the 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 should not be considered as an alternative to net income (determined in accordance with GAAP) as an indicator of our financial performance, or as an alternative to cash flows from operating activities (determined in accordance with GAAP) as a measure of our liquidity.

Year Ended December 31, 2004 Compared with Year Ended December 31, 2003

Net sales. On a combined basis, net sales increased $37.2 million, or 13.9%, from $266.8 million in 2003 to $304.0 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 the Company to increase sales prices and recover material surcharges 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, international sales decreased 1.7% and domestic sales increased 14.6% resulting in a combined increase of 11.6%.

Gross profit. On a combined basis, gross profit increased $10.9 million, or 18.6%, from $58.5 million (21.9% of net sales) in 2003 to $69.4 million (22.8% 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 $0.8 million from $49.4 million in 2003 to $50.2 million in 2004. As a percentage of net sales, selling, general and administrative expenses decreased from 18.5% in 2003 to 16.5% in 2004. The change in selling, general and administrative expenses reflect 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 the Predecessor and cost savings resulting from restructuring activities completed in prior years. On a constant currency basis, selling, general and administrative expenses decreased by 1.0%, or $0.5 million, from $49.4 million in 2003 to $48.9 million in 2004.

Research and development expenses. Research and development expenses increased $0.5 million, or 18.5%, from $2.7 million in 2003 to $3.2 million in 2004. The increase was primarily due to the change in currency valuations.

Restructuring charge, asset impairment and transition expenses. The Predecessor recorded 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 in the Recent Cost Savings and Productivity Enhancement Initiatives above, were taking place.

EBITDA. To reconcile the 2004 net income to EBITDA, on a combined basis, we excluded $5.2 million provision of income taxes, $5.7 million of interest expense and $8.2 million of depreciation and amortization expenses. Our 2004 EBITDA does not take into account a $1.2 million gain on sales of assets and other non-operating expenses and $0.9 million in restructuring, asset impairment and transition expenses. Taking into account the foregoing adjustments, our resulting EBITDA increased $9.2 million, or 62.1%, from $14.8 million for the year ended December 31, 2003 to $24.0 million for the same period in 2004 due to the factors described above.

Interest expense. The Company recorded consolidated interest expense of $1.5 million during the period from Inception to December 31, 2004 primarily due to the 9% Senior Secured Notes and the amortization of related deferred financing costs. The Predecessor recorded interest expense of $4.3 million during the 11 month period ending 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.

(Gain) on sale of assets and other non-operating (income) expense. The Predecessor recorded a gain on sale of assets of $1.2 million during the 11 month period ending November 30, 2004 relating to the sale of surplus real estate. This gain was offset by other expenses primarily related to the write-off of deferred loan costs which comprised the majority of the non-operating expense recorded in 2003.

Provision for income taxes. The provision for income taxes was $5.2 million on a combined basis in 2004, versus a benefit of $1.6 million for 2003. The increase in the provision for 2004 was primarily a result of the increase in our taxable income for the year.

Predecessor Results—Year Ended December 31, 2003 Compared with Year Ended December 31, 2002

Net sales. Net sales increased $13.6 million, or 5.4%, from $253.2 million in 2002 to $266.8 million in 2003. Net sales increased primarily due to increased sales to OEM customers in the turf and garden, transportation and material handling markets and the positive impact of foreign

exchange rates, partially offset by weak demand in the general industrial market in Europe. On a constant currency basis, international sales decreased 3.8% and domestic sales increased 2.8% resulting in a combined increase of 1.2%.

Gross profit. Gross profit decreased $4.2 million, or 6.7%, from $62.7 million (24.8% of net sales) in 2002 to $58.5 million (21.9% of net sales) in 2003. The decrease was primarily due to the negative impact of our restructuring activity on productivity.

Selling, general and administrative expenses. Selling, general and administrative expenses increased $1.1 million, or 2.3%, from $48.3 million in 2002 to $49.4 million in 2003. As a percentage of net sales, selling, general and administrative expenses decreased from 19.1% in 2002 to 18.5% in 2003. On a constant currency basis, selling, general and administrative expenses decreased by 3.9%, or $1.9 million, from $49.3 million in 2002 to $47.4 million in 2003. The decrease on a constant currency basis was primarily due to cost savings realized during 2003 from the Predecessor's restructuring activities initiated in 2002.

Research and development expenses. Research and development expenses decreased $0.4 million from $3.1 million in 2002 to $2.7 million in 2003. The increase was primarily due to a reduction in efforts required as a result of the completion of the Recent Cost Savings and Productivity Enhancement Initiatives, as described above.

Restructuring charge, asset impairment and transition expenses. Restructuring charge, asset impairment and transition expenses decreased $16.7 million from $27.8 million in 2002 to $11.1 million in 2003. These costs were below the amounts recorded in prior years due to the timing of related expenditures, as described in the Recent Cost Savings and Productivity Enhancement Initiatives above.

EBITDA. To reconcile the 2003 net income to EBITDA, on a combined basis, we excluded $1.6 million benefit of income taxes, $5.4 million of interest expense and $8.4 million of depreciation and amortization expenses. Our 2003 EBITDA does not take into account a $0.5 million loss on sale of assets and other non-operating expense and $11.1 million in restructuring, asset impairment and transition expenses. Taking into account the foregoing adjustments, our resulting EBITDA decreased $6.1 million, or 29.2%, from $20.9 million for the year ended December 31, 2002 to $14.8 million for the same period in 2003 due to the factors described above.

Interest expense. Interest expense decreased $0.1 million from $5.5 million in 2002 to $5.4 million in 2003. The decrease was primarily due to lower interest rates which offset the impact from increased borrowings.

(Gain) on sale of assets and other non-operating (income) expense. Other non-operating income was $0.3 million in 2002 compared to other non-operating expense of $0.5 million in 2003. The increase in expenses was primarily due to the write-off of deferred loan costs due to debt refinancing.

Provision (benefit) for income taxes. Provision (benefit) for income taxes was a provision of $2.5 million for 2002 and a benefit of $1.6 for 2003. The increase in the benefit for income taxes was primarily due to Ameridrives and Warner Electric being converted from pass-through entities to taxable entities during 2003.

Loss from operation and disposal of discontinued operations, net of income taxes. The net loss from discontinued operations for 2002 related to the net loss of Bay City Forge, which was sold in December 2002. Bay City Forge was classified as discontinued operations during 2002.

Cumulative effect of change in accounting principle—goodwill impairment. The cumulative effect of accounting change during 2002 relates to the write-off of goodwill as a result of the adoption of SFAS No. 142,Goodwill and Other Intangible Assets.

Liquidity and Capital Resources

Historical (Predecessor) Cash Flows

Historically, PTH financed its 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 Corporation.

Net cash flow provided by (used in) the Predecessor's operating activities, in the 11 months ending November 30, 2004 and the years ending December 31, 2003 and 2002 was $3.2 million,
$(16.7) million and $19.9 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 use 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.

Historically, the Predecessor's investing activity was limited to the use of cash to purchase fixed assets which ranged from $5.0 to $6.0 million. The Company operates in a mature business and as a result does not have significant ongoing capital expenditure requirements. In recent years, surplus property was also sold which provided $4.4 million during the 11 months ending November 30, 2004 and $3.7 million and $1.3 million in the year ending December 31, 2003 and 2002, respectively.

Following the Acquisition and Related Transactions

Following the Acquisition and Related Transactions, our primary source of liquidity will be cash flow from operations and borrowings under our senior revolving credit facility. We expect that ongoing requirements for debt service and capital expenditures will be funded from these sources.

We expect to make capital expenditures of approximately $5.0 million in 2005. These capital expenditures will support on-going business needs.

We incurred substantial indebtedness in connection with the Acquisition. As of December 31, 2004 we had approximately $166.2 million of total indebtedness outstanding (including capital leases) which, on an annual basis, will result in approximately $17.0 million in interest expense. Our significant debt service obligations following the Acquisition and Related Transactions could, under certain circumstances, have material consequences.

Our senior revolving credit facility provides for senior secured financing of up to $30.0 million, including $10.0 million available for letters of credit. At April 1, 2005 there were $4.2 million of outstanding borrowings and $2.7 million of outstanding letters of credit under our senior revolving credit facility.

Our ability to make scheduled payments of principal and interest, to refinance our indebtedness, including the notes, or to fund planned capital expenditures will depend on our ability to generate cash in the future. Our ability to generate cash is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control.

Based on our current level of operations, we believe that 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 at least the next two years. We may, however, need to refinance all or a portion of the principal amounts of the notes on or prior to maturity.

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 secured credit facility in an amount sufficient to enable us to service our

indebtedness, including the notes, or to fund our other liquidity needs. In addition, we cannot assure you that we will be able to refinance any of our indebtedness, including our senior revolving credit facility and the notes as they become due. 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. See "Risk Factors—Risks Relating to this Offering—Our substantial level of indebtedness could adversely affect our financial condition and prevent us from fulfilling our obligations on the notes."

Contractual Obligations

The following table is a summary of contractual cash obligations as of December 31, 2004 (in millions):

⁽¹⁾: We have entered into an advisory services agreement with Genstar Capital which requires the annual payment of $1.0 million for management and consulting services until the agreement is terminated per mutual agreement between Altra and Genstar Capital. See "Certain Relationships and Related Party Transactions—Genstar Capital Management Agreement."
⁽²⁾: 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). There were $4.2 million of outstanding borrowings and $2.7 million of outstanding letters of credit at April 1, 2005.

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 begun a preliminary analysis of the American Jobs Creation Act that was recently passed by both the U.S. House of Representatives and Senate and signed by the President in October of this year. The Act provides a deduction that has the effect of reducing our tax rate and will be phased in over the next five years.

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. The June-through-November period is typically the low season for us and our customers in the turf and garden market. Seasonality 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.

Recent Accounting Pronouncements

In December 2003, Congress passed the Medicare Prescription Drug Improvement and Modernization Act of 2003 (the Act). The Act established a prescription drug benefit under Medicare, known as Medicare Part D, and a federal subsidy to sponsors of retiree health care benefit plans that are at least actuarially equivalent to Medicare Part D. The Financial Accounting Standards Board (the "FASB") has issued Staff Position No. 106-2, "Accounting and Disclosure Requirements Related to the Medicare Prescription Drug Improvement and Modernization Acts of 2003," which requires that the effects of the federal subsidy be considered an actuarial gain and recognized in the same manner as other actuarial gains and losses. A $0.3 million gain was recognized in 2004, on a combined basis, as a result of the Act.

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.

Effective January 1, 2003, the Predecessor adopted SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities." This Statement requires companies to recognize costs associated with exit or disposal activities when they are incurred rather than at the date of a commitment to an exit or disposal plan. Examples of costs covered by the standard include lease termination costs and certain employee severance costs that are associated with a restructuring, discontinued operation, plant closing, or other exit or disposal activity. SFAS No. 146 was to be applied prospectively to exit or disposal activities initiated after December 31, 2002. The adoption of this standard did not have a material impact on the Predecessor's consolidated financial statements.

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.

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, 2004, the aggregate total assets (based on book value) of foreign subsidiaries were $49.0 million, representing approximately 16.7% of our total assets (based on book value). Our foreign currency exchange rate exposure is primarily with respect to the Euro.

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 floating rates of interest. See "Description of Certain Indebtedness."

The Sarbanes-Oxley Act of 2002 and Material Weakness in Internal Control

In connection with their audit of the Company's 2004 financial statements, the Company's independent auditors expressed concerns that as of the date of their opinion, the Company's corporate financial management organization was limited to the Chief Financial Officer with support from outside consultants, divisional resources and certain transition services from Colfax Corporation. Based upon these limited corporate resources, the independent auditors noted that the Company was unable to report financial information in a timely manner. Based upon the timely financial reporting required of a public company, the outside auditors informed the senior management and Audit Committee of the Board of Directors that they believe this is a material weakness in internal controls. The Company is actively taking steps to address this situation. However, if we are unable to remediate this material weakness in time to satisfy the internal control requirements of Section 404 of the Sarbanes-Oxley Act of 2002 as of December 31, 2006, or if other 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 our bonds.

BUSINESS

Our Company

Our product portfolio includes industrial clutches and brakes, enclosed gear drives, open gearing, couplings, machined-race bearings and other related products. These products are sold directly to large OEMs, such as John Deere, Carrier and General Electric, and to leading distributors, such as Motion Industries, Applied Industrial Technologies, Kaman Industrial Technologies and W.W. Grainger. These distributors sell to the replacement parts market, or aftermarket, as well as to small and medium-size OEMs. Because many of our products have a recurring replacement cycle, we believe aftermarket sales to replace our large installed base of products have generated a significant amount of our annual revenue, strongly contributed to our margins and reduced our exposure to normal economic, market and regional business fluctuations. Our customers operate in a diverse group of industries, including automotive, general industrial, material handling, mining, power generation, transportation and turf and garden.

Industry Overview

reliability and their service and technical support capabilities to maintain attractive margins on products and gain market share.

Business Strengths

We believe the following business strengths have allowed us to develop and maintain a leading position within the mechanical power transmission industry:

Leading Brand Awareness. For 2004, a majority of our revenue was generated from products that, according to the Motion Systems Design magazine survey, are recognized as having the #1 or #2 leading position in terms of brand awareness in their respective product categories. We believe our superior brand recognition is the result of a long operating history, reputation for product quality and a focus on customer service, which improves our ability to retain existing customers, win new business and expand market share.

Strong Distribution Channels. We have long-term relationships with leading industrial power transmission distributors such as Applied Industrial Technologies, Kaman Industrial Technologies, Motion Industries and W.W. Grainger. Through these large, multi-branch distributors, and regional and independent local distributors, we sell our products through over 3,000 outlets across the world. In addition to our distributor relationships, we have over 400 direct OEM customers, including many long-standing relationships with well established companies such as Carrier, General Electric and John Deere. Our OEM relationships span a variety of industries and end markets. These customers assist in increasing brand leverage through our distributor network by generating aftermarket demand for our products.

Large Installed Base of Products with Stable, Recurring Revenue Streams. For over 75 years, our products have been used in a wide range of industrial applications, resulting in a large installed base of products. We believe our strong customer relationships and brand loyalty have enabled us to capture a high percentage of aftermarket product sales. A significant amount of our revenues have historically come from the sale of replacement products, which generate recurring revenue and help to mitigate the cyclical nature of the broader economy.

Diversified Revenue Base. Our broad product offering serves a wide range of end markets, customers and geographic regions. The markets that we serve include automotive, general industrial, material handling, mining, power generation, transportation and turf and garden. Our customers are distributed across many industries. We are not dependent on any single customer or distributor. Our largest distributor has been our customer for over 50 years and represented approximately 10.2% of our net sales for 2004. Our next largest customer represented less than 4.1% of our net sales for 2004. In addition, approximately 24.0% of our net sales for 2004 were derived outside of North America, primarily in Europe and Asia. We believe the diversity of our customers, markets and products helps to reduce our exposure to specific industries, geographies and economic cycles. In addition, as companies increasingly limit their supplier base, we believe our diversified product offering and multinational service capabilities position us to capitalize on this trend and increase market share.

Proven Operational Efficiencies. We have implemented a number of operational excellence initiatives, which we refer to as the Altra Business System, or ABS. ABS is a disciplined business system designed to instill a culture of continuous improvement into all aspects of our operations and strategic planning. We believe that our commitment to the training and involvement of our associates in the use of ABS process tools and continuous improvement methodologies has given our organization the ability to effect rapid positive change and to react to changing requirements and market conditions. We believe this has allowed us to provide high-quality, more profitable service to our customers.

Experienced Senior Management Team. Our experienced senior management team has an average of 28 years of general industrial experience. In addition, our senior management team has substantial experience in integrating acquired businesses and implementing lean manufacturing techniques.

Business Strategy

Increase Market Share in our Existing Markets:

• Leverage our Sales and Distribution Network. Due to our strength of brand, breadth of product offering and large installed base of products, we have developed strong relationships with our distribution partners. We intend to continue to leverage our relationships with our distributors to gain shelf space and sell new products. For example, in 2002 we launched a product in our clutch brake line that incorporated similar features and technology as competitive products. Due to the strength of our Warner Electric brand, we quickly captured market share and generated net sales of approximately $1.9 million for 2004. In addition, we will continue to actively pursue new OEM opportunities with innovative and cost-effective product designs and applications to help grow and protect our aftermarket revenues. This strategy capitalizes on end user brand preference for our products, generating pull-through aftermarket demand from our distribution channel. We believe this strategy also allows our distributors to achieve high profit margins, which further enhances our preferred position with them.

• Focus on Strategic Marketing. We intend to continue to build our strategic marketing organization to focus on new growth opportunities in key, fast-growing OEM and end user markets, including elevators, food processing, material handling, packaging machinery and turf and garden. Through a systematic process that leverages our core brands and products, we seek to identify attractive 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. In support of our strategic marketing initiatives, we recently began to redirect our sales organization to focus on key accounts in specific markets.

• Accelerate New Product and Technology Development. In a number of our strategic markets, we have identified opportunities to expand our served market by introducing new products and by improving existing products. We intend to refocus our efforts with our integrated product management, engineering and manufacturing teams to work closely with customers to improve existing application performance, reduce overall cost of ownership and develop new products and technologies.

Capitalize on Growth and Sourcing Opportunities in the Asia-Pacific Market. We intend to leverage our five established sales offices in Australia, Hong Kong, Taiwan, Thailand and Singapore, as well as expand our manufacturing presence in Asia beyond our current plant in Shenzhen, China, to drive increased sales in the high-growth Asia-Pacific region. This region also offers excellent opportunities for low-cost country sourcing of procured material. During 2004, we sourced approximately 10% of our purchases through low-cost country sourcing, from which we experienced net cost reductions of approximately 40% for these products. In the next three years, we intend to utilize our global sourcing office in Shanghai to increase our current level of low-cost country sourcing to 20% of purchases. We believe there are also opportunities to outsource some of our production from higher cost North American and Western European locations to China.

Continue to Improve Operational and Manufacturing Efficiencies. We believe we can improve profitability through cost control, overhead rationalization, global process optimization, continued

implementation of lean manufacturing techniques and strategic pricing initiatives. In addition, we have identified opportunities to further reduce costs by continuing to outsource the production of components and finished products to lower-cost manufacturing sources outside North America and Western Europe. 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 consolidating purchasing processes. Through these and other initiatives, we have identified annualized cost savings of $9 million that we believe we can realize by the end of 2007. We also intend to increase revenue and profitability by identifying and implementing strategic transactional pricing opportunities.

Selectively Pursue Acquisition, Alliance and Partnership Opportunities. The highly fragmented industrial power transmission market is comprised of many niche participants and offers numerous opportunities for consolidation. We will continue to examine potential acquisition opportunities by utilizing a disciplined approach to the evaluation and integration of acquisitions. We plan to opportunistically seek companies that our senior management team believes will enhance our global presence, broaden our product portfolio, increase our market share and provide operational and financial benefits. As a result of acquiring and successfully integrating several companies in the past eight years, we are experienced at identifying, executing and integrating synergistic opportunities and improving the operating performance of acquired businesses. In addition, we intend to establish branding alliances and partnerships with companies that maintain a strong cost and technology position but lack the infrastructure to penetrate the North American, European or Asian markets.

Products

We produce and market a wide variety of mechanical power transmission products. Our product portfolio includes industrial clutches and brakes, enclosed gear drives, open gearing, couplings, machined-race bearings and other related products which are sold across a wide variety of industries. Our products benefit from our industry leading brand names including Ameridrives, Boston Gear, Warner Electric, Formsprag Clutch, Industrial Clutch, Kilian, Marland Clutch, Nuttall Gear, Stieber and Wichita Clutch. Our products serve a wide variety of end markets including automotive, general industrial, material handling, mining, power generation, transportation and turf and garden. We primarily sell our products to OEMs such as John Deere, Carrier and General Electric 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.

Our primary products include:

Products	Principal Brands	Principal Markets	Sample Applications
Clutches, Clutch Brakes	Warner Electric, Formsprag Clutch, Stieber, Wichita Clutch	Material handling, turf and garden, aerospace, marine and energy	Forklifts, elevators, lawn mowers and winches
Enclosed Gear Drives	Boston Gear, Nuttall Gear	Food processing, material handling and specialty machinery	Conveyors, industrial ovens and mixers

Couplings	Ameridrives	Steel, power generation and petrochemical	Strip mills and turbines
Machined-race Bearings	Kilian	General industrial applications and automotive	Sliding doors, steering columns, furniture and conveyors

Our products are moving, wearing components that over time require replacement and, as a result, give rise to an on-going aftermarket opportunity. We believe that customers demonstrate a strong preference for replacing used products with new products of the same brand, our broad installed base encourages strong demand and makes our portfolio both valuable and attractive to our distributor network.

Sales and Marketing

We sell our products in over 70 countries to over 400 direct OEM customers and over 3,000 distributor outlets through our direct sales force consisting of over 250 sales and marketing personnel and our independent sales representatives. We believe that our worldwide sales and distribution presence enables us to provide timely and responsive support and service to our customers, many of which operate internationally, 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 mechanical power transmission solutions for a host of industrial applications.

Distribution

Our mechanical power transmission components are either incorporated into end products sold by OEMs or sold through industrial distributors as aftermarket products to end users and smaller OEMs. Our business is geographically diversified, with 76.0% of net sales for 2004, on a combined basis, derived from customers in North America, 19.4% from customers in Europe and 4.6% from customers in Asia and other areas. We sell to over 3,000 distributor outlets, providing us with an extensive global sales network. Rather than serving as passive conduits for delivery of product, our industrial distributors are active participants influencing product purchasing decisions in the mechanical power transmission industry. In addition, distributors play a critical role through stocking inventory of our products, which affects the accessibility of our products to aftermarket buyers.

Competition

We operate in highly fragmented and very competitive markets within the mechanical power transmission market. As a result, we compete against numerous businesses. 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 and have greater financial and other resources than we do. In particular, we compete with Emerson Power Transmission Manufacturing, L.P, Ogura Industrial Corporation, 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 engineer 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 prices 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 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 mechanical power transmission 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 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: Ameridrives, Boston Gear, Formsprag Clutch, Industrial Clutch, Kilian, Marland Clutch, Nuttall Gear, Stieber, Warner Electric and Wichita Clutch.

Research and Development and Product Engineering

We closely integrate new product development with marketing, manufacturing and product engineering in meeting the needs of our customers. We have product engineering teams that work to enhance our existing products and develop new product applications for our growing base of customers that require custom solutions. We believe these capabilities provide a significant competitive advantage in the development of high quality industrial power transmission products. Our product engineering teams focus on:

•: lowering the cost of manufacturing our existing products;
•: redesigning existing product lines to increase their efficiency or enhance their performance; and
•: developing new product applications.

Employees

customers may be subject to work stoppages, which could seriously impact the profitability of our business."

Properties

In addition to our leased headquarters in Quincy, Massachusetts, we maintain 16 production facilities, eight of which are located in the United States, two in Canada, five in Europe and one in China. The following table lists all of our facilities, other than sales offices and distribution centers, as of December 31, 2004 indicating the location, principal use and whether the facilities are owned or leased.

Suppliers and Raw Materials

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

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. Many of our operations require environmental permits and controls to prevent and limit air and water pollution. These permits contain terms and conditions that impose limitations on our manufacturing activities, production levels and associated activities 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 are also subject to the federal Occupational Health and Safety Act and similar state and foreign laws which impose requirements and standards of conduct on our operations for the health and safety of our workers. We periodically review our procedures and policies for compliance with environmental and health and safety requirements. We believe that our operations are generally in compliance with applicable environmental regulatory requirements or that any non-compliances will not result in a material liability or cost to achieve compliance. Historically, the costs of achieving and maintaining compliance with environmental and health and safety 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 entire cost of investigation or remediation of contaminated sites upon the current site owners, the site owners and operators at the time the contamination occurred, and upon parties who generated wastes or transported or sent those wastes to an off-site facility for treatment or disposal, regardless of whether the owner owned the site at the time of the release of the hazardous substances or the lawfulness of the original waste disposal activity. As a practical matter, however, the costs of investigation and remediation are generally allocated among the viable responsible parties on some form of equitable basis. There is or could be contamination at some of our current or formerly owned or operated facilities, primarily related to historical operations at those sites, for which we could be liable under applicable environmental laws. To the extent we believe there may be a material risk to human health, safety or the environment, we or other parties who have contractual liability for the environmental conditions at those sites are addressing, or have plans to address, environmental conditions at certain of those facilities in accordance with applicable environmental laws and regulations. Our costs or liability in connection with some of those sites 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. We are, however, being indemnified, or expect to be indemnified by, Colfax Corporation, subject to certain caps or limitations on the indemnification, for certain of those 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 Matters

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.

Equity Incentive Plan

In connection with the Acquisition, Altra Holdings, Inc., our parent, 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 common stock of Holdings. The maximum number of shares of common stock, par value $0.001, of Holdings that may be issued under the terms of the equity incentive plan is 4,000,000. The maximum number of shares that may be subject to "incentive stock options" (within the meaning of Section 422 of the Internal Revenue Code) is 3,500,000 shares. Plan participants are individually subject to a maximum number of shares with respect to which awards may be granted in any calendar year during the term of the equity incentive plan. The board of directors of Holdings or a committee appointed by the board of directors will administer the equity incentive plan and will have discretion to establish the specific terms and conditions for each award. Our employees, consultants and directors will be eligible to receive awards under the Holdings equity incentive plan. Restricted stock, stock units and cash awards may constitute performance-based awards in accordance with Section 162(m) of the Internal Revenue Code at the discretion of the committee. Generally, any grant of restricted stock under our plan will be subject to vesting requirements. Restricted stock granted under our plan will vest in five equal annual installments. A grantee of restricted stock will obtain a 100% vested interest in a particular grant of restricted stock if such employee is continuously employed by us for five years after the date of grant. 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. 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.

Pension

Gerald Ferris and Craig Schuele previously participated in the Colfax PT Pension Plan, however on December 31, 1998 Mr. Ferris and Mr. Schuele's participation in and benefits accrued under such plan were frozen. Under the provisions of the plan, upon reaching the normal retirement age of sixty-five, Messrs. Ferris and Schuele will receive annual payments of approximately $38,700 and $10,800 respectively. As part of the Acquisition, we were obligated to assume certain liabilities of the Colfax PT Pension Plan, including such future payments to Messrs. Ferris and Schuele, and have established a new plan, the Altra Industrial Motion, Inc. Retirement Plan, providing substantially similar benefits as provided under the Colfax PT Pension Plan. See "Risk Factors—Risks Relating to Our Business—We face risks associated with our post-retirement and post-employment obligations to employees."

Director Compensation

All members of our board of directors are reimbursed for their usual and customary expenses incurred in connection with attending all board and other committee meetings. Independent directors, Frank Bauchiero and Larry McPherson, receive director fees of $40,000 per year. In January of 2005, each of the independent directors was also granted 68,250 shares of restricted common stock, which stock is subject to vesting over a period of five years.

Severance Agreements

We assumed severance agreements with the following named executive officers upon the consummation of the Acquisition:

•: Charles W. Nims
•: Matthew F. Taylor
•: Craig Schuele
•: Gerald Ferris
•: Timothy McGowan
•: Edward L. Novotny

Each of the severance agreements provide 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 Acquisition by us without "cause" or by the executive for "good reason" (each as defined in the severance agreements), we will 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 elects continuation coverage under our health care and dental plans, subject to the executive's continued co-payment of the applicable premiums, we will 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, will commence after the period of salary continuation. Any severance benefit will 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.

Option/SAR Grants in Last Fiscal Year

There were no option/SAR grants in 2004.

Employment Arrangements and Change in Control Arrangements

Executive Employment Agreements. Three of our senior executives, Michael Hurt, David Wall and Carl Christenson have entered into employment agreements with Altra. Mr. Hurt's agreement has a three-year term and Messrs. Wall and Christenson's agreements have five-year terms and 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.

Stockholders Agreement. Under Amended and Restated Stockholders Agreement, Altra Holdings has the right to purchase for fair market value any management stockholder's management stock upon termination of such management stockholder's employment for any reason;provided that, if such employee is terminated for "cause", Altra Holdings may repurchase such shares at the lower of fair market value and cost. In the case of Altra Holdings' common stock, fair market value shall be determined in good faith by the Board of Directors of Altra Holdings (with a discount for lack of marketability or minority interest). In the case of the Altra Holdings' preferred stock, fair market value shall be the greater of (a) $1.00 per share (as adjusted for stock splits, dividends and the like) and (b) the fair value as determined in good faith by the Board of Directors of Altra Holdings, on the basis of a sale to a willing, unaffiliated buyer in an arm's length transaction.

Restricted Stock Agreements. In general Altra Holdings' restricted stock agreements provide that Altra Holdings has the right to repurchase a grantee's vested restricted stock at fair market value upon termination of such grantee's employment for any reason;provided that, if such employee is terminated for "cause", Altra Holdings may repurchase such shares at the lower of fair market value and cost. Fair market value shall be determined in good faith by the Board of Directors of Altra Holdings (with a discount for lack of marketability or minority interest). In addition, should Genstar Capital determine to sell any securities of Altra Holdings that results in a change of control, then upon Genstar Capital's request the grantee shall sell to the proposed purchaser a similar percentage of such grantee's restricted stock in Altra Holdings.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

All of our issued and outstanding common stock is owned by our parent, Altra Holdings. As of April 30, 2005, affiliates of Genstar Capital owned approximately 66.8% of the outstanding capital stock of Altra Holdings while the majority of the remainder is owned by Caisse de dépôt et placement du Québec, or CDPQ, and members of our senior management.

The following table sets forth information with respect to the beneficial ownership of the capital stock of Altra Holdings as of April 30, 2005:

•: each person known by us to own beneficially more than 5% of the capital stock;
•: each of the directors of Altra Holdings;
•: each of our named executive officers; and
•: all of the directors and our executive officers as a group.

The amounts and percentages of shares beneficially owned are reported on the basis of SEC regulations governing the determination of beneficial ownership of securities. Under SEC rules, a person is deemed to be a "beneficial" owner of a security if that person has or shares voting power or investment power, which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Securities that can be so acquired are deemed to be outstanding for purposes of computing any other person's percentage. Under these rules, more than one person may be deemed to be a beneficial owner of the same securities and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest.

Except as otherwise indicated in these footnotes, each of the beneficial owners listed has, to our knowledge, sole voting and investment power with respect to the shares of capital stock.

DESCRIPTION OF CERTAIN INDEBTEDNESS

The following summary of certain provisions of the instruments evidencing our material indebtedness does not purport to be complete and is subject to and qualified in its entirety by reference to, all of the provisions of the corresponding agreements, including the definitions of certain terms therein that are not otherwise defined in this prospectus.

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. In connection with the offering of the old notes, we and all of our U.S. domestic subsidiaries (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 revolving credit facility is available in the form of letters of credit and amounts repaid under the 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 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 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 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 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 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 $1.5 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. Our obligations, along with the obligations of the other Borrowers under the senior revolving credit facility, and these guarantees are secured by substantially all our assets, 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 us, 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 our tangible and intangible assets and 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) 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).

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) and a maximum annual limit on capital expenditures. The senior revolving credit facility also contains customary representations and warranties, affirmative covenants and events of default, including change of control, cross-defaults to other debt and material judgments.

Capital Leases

We have entered into capital leases for certain buildings and equipment primarily located at our European operations. As of December 31, 2004 we had approximately $1.1 million of outstanding capital lease obligations.

DESCRIPTION OF NOTES

The old notes were, and the registered notes will be, issued under an Indenture (the "Indenture"), dated as of November 30, 2004, by and among us, the Guarantors and the Bank of New York Trust Company, N.A., as Trustee. The terms of the notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act.

The following description is only a summary of the material provisions of the Indenture. We have filed copies of the indenture as an exhibit to the registration statement of which this prospectus forms a part. You may also request copies of this agreement at our address set forth under the heading "—Additional Information." We urge you to read the Indenture because it, not this description, defines your rights as holders of the notes.

In the following summary:

•: "registered notes" refers to the registered notes being offered by this prospectus;
•: "old notes" refers to your old notes that may be exchanged for new notes in the exchange offer;
•: "notes" refers collectively to the registered notes and the old notes;
•: references to the "Company" include only Altra Industrial Motion, Inc. and not any of its subsidiaries; and
•: you can find definitions of various terms under the subsection "—Certain Definitions."

The Company will issue the registered notes solely in exchange for an equal principal amount of old notes in denominations of $1,000 and integral multiples of $1,000. The Trustee will initially act as Paying Agent and Registrar. The notes may be presented for registration or transfer and exchange at the offices of the Registrar. The Company may change any Paying Agent and Registrar without notice to holders of the notes. Any notes that remain outstanding after the completion of this exchange offer, together with the registered notes issued in connection with this exchange offer, will be treated as a single class of securities under the Indenture.

Brief Description of the Notes and the Guarantees

The Notes

The Notes will:

•: be senior obligations of the Company;
•: rank equally in right of payment with all existing and future senior obligations of the Company (including under the Credit Agreement) and senior in right of payment to all existing and future Indebtedness that by its terms is subordinated to the Notes;
•: be secured by second priority security interests in substantially all of the assets of the Company, subject to Permitted Liens; and
•: be unconditionally guaranteed, jointly and severally, by all of the Company's Domestic Restricted Subsidiaries, as set forth under "—Guarantees" below.

The Guarantees

Each Guarantee of a Guarantor will:

•: be a senior obligation of such Guarantor;

•: rank equally in right of payment with all existing and future senior obligations of such Guarantor (including under the Credit Agreement) and senior in right of payment to all existing and future Indebtedness that by its terms is subordinated to the Guarantee of such Guarantor; and
•: be secured by a second priority security interest in substantially all of the assets of such Guarantor, subject to Permitted Liens.

The Notes will be effectively subordinated to all first priority secured Indebtedness of the Company to the extent of the assets securing such Indebtedness, including, without limitation, Indebtedness of the Company under the Credit Agreement, Purchase Money Indebtedness, Capitalized Lease Obligations, secured Acquired Indebtedness and other secured Indebtedness permitted to be incurred under the Indenture. As of April 1, 2005, the Notes are subordinated to approximately $4.1 million of outstanding borrowings and $2.7 million of outstanding letters of credit issued on behalf of the Company. We have up to an additional $23.2 million of borrowing capacity under our Credit Agreement, all of which would become first priority secured Indebtedness, if borrowed.

The Notes will be structurally subordinated to all of the existing and future liabilities of our Foreign Subsidiaries. In the event of a bankruptcy, liquidation or reorganization of any of our Foreign Subsidiaries, such Foreign Subsidiaries will pay the holders of their debt, their trade creditors and holders of preference shares, if any, before they will be able to distribute any of their assets to the Company. See "Risk Factors—The notes will be structurally subordinated to all obligations of our non-guarantor subsidiaries."

As of the date of the Indenture, all of our Subsidiaries will be Restricted Subsidiaries. However, under certain circumstances in compliance with "—Certain Covenants—Limitation on Restricted Payments," we will be permitted to designate certain of our Subsidiaries as "Unrestricted Subsidiaries."

Principal, Maturity and Interest

The Company will issue the registered notes in fully registered form in denominations of $1,000 and integral multiples thereof. The Notes are unlimited in aggregate principal amount, of which $165.0 million in aggregate principal amount will be issued in the exchange offer. The Company may issue additional Notes (the "Additional Notes") from time to time, subject to compliance with the terms of the Indenture. The Notes and any Additional Notes will be substantially identical other than the issuance dates. Unless the context otherwise requires, for all purposes of the Indenture and this "Description of the Notes," references to the Notes include any Additional Notes actually issued. Any Additional Notes issued after this Offering will be secured equally and ratably with the Notes. As a result, the issuance of Additional Notes will have the effect of diluting the security interest in the Collateral for the then outstanding Notes. Because any Additional Notes may not be fungible with the Notes for federal income tax purposes, they may have a different CUSIP number or numbers and be represented by a different global Note or Notes.

The Notes will mature on December 1, 2011.

Interest on the Notes will be payable semiannually in cash on each June 1 and December 1, commencing on June 1, 2005 to the Persons who are registered Holders at the close of business on each May 15 and November 15 immediately preceding the applicable interest payment date. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from and including the Issue Date. Interest on the Notes will accrue at a rate per annum of 9%.

Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. Additional Interest may accrue on the Notes in certain circumstances pursuant to the Registration Rights Agreement.

Collateral

The Notes and the Guarantees will be secured by a second priority lien on substantially all of the assets of the Company and the Guarantors (other than the Syracuse Facility and any other existing and future owned real property located in the State of New York), including a pledge of the Capital Stock owned directly by the Company and the Guarantors;provided, that no such pledge will include more than 65% of the Voting Stock of our Foreign Subsidiaries directly owned by the Company or any Guarantor. In the event that we or the Guarantors, as applicable, execute first-priority mortgages of the Syracuse Facility or any other existing and future owned real property in the State of New York under the Credit Agreement in the future, the Indenture provides that we must simultaneously execute second-priority mortgages of such real property in favor of the Collateral Agent for the benefit of the Holders of the Notes.

The Collateral securing the Notes and the Guarantees will also serve as collateral to secure the obligations under the Credit Agreement. The Company, the Guarantors and the Collateral Agent, on behalf of itself, the Trustee and the Holders, and the Administrative Agent, on behalf of itself and the Lenders, will enter into the Intercreditor Agreement. The Intercreditor Agreement will provide, among other things, that:

(1) Liens on the assets securing the Notes will be junior to the Liens in favor of the Administrative Agent under the Credit Agreement, and consequently, the Lenders will be entitled to receive proceeds from the foreclosure of any such assets prior to the Holders,

(2) during any insolvency proceedings, the Administrative Agent and the Collateral Agent will coordinate their efforts to give effect to the relative priority of their security interests in the Collateral, and

(3) the procedure for enforcing the Liens on the collateral, including (a) the distribution of sale, insurance or other proceeds of the Collateral and (b) permitting the Administrative Agent and the Lenders under the Credit Agreement to enter into and use the Collateral securing the Notes in order to realize on their collateral.

The Intercreditor Agreement will also provide that the Collateral Agent and the Administrative Agent will provide notices to each other with respect to the occurrence of events of default and the acceleration of the Notes or the Indebtedness outstanding under the Credit Agreement, as the case may be.

Upon the occurrence of an Event of Default, the proceeds from the sale of Collateral securing the Notes may be insufficient to satisfy the Company's obligations under the Notes. No appraisals of any of the Collateral have been prepared in connection with the Offering. Moreover, the amount to be received upon such a sale would be dependent upon numerous factors, including the condition, age and useful life of the Collateral at the time of the sale, as well as the timing and manner of the sale. By its nature, all or some of the Collateral will be illiquid and may have no readily ascertainable market value. Accordingly, there can be no assurance that the Collateral, if saleable, can be sold in a short period of time.

Subject to the terms of the Collateral Agreements, the Company and the Guarantors will have the right to remain in possession and retain exclusive control of the Collateral securing the Notes to freely operate the Collateral and to collect, invest and dispose of any income therefrom in their sole discretion.

The security interests granted by the Company and the Guarantors that secure the Notes and the Guarantees will also be junior to Permitted Liens securing other existing Indebtedness. Subject to the restrictions on incurring Indebtedness in the Indenture and the Credit Agreement, the Company and its

Restricted Subsidiaries will also have the right to grant Liens securing Acquired Indebtedness, Capital Lease Obligations and Purchase Money Indebtedness.

To the extent third parties hold Permitted Liens, such third parties may have rights and remedies with respect to the property subject to such Liens that, if exercised, could adversely affect the value of the Collateral. Given the intangible nature of certain of the Collateral, any such sale of such Collateral separately from the assets of the Company as a whole may not be feasible. The ability of the Company to grant or perfect a security interest in certain Collateral may be limited by legal or other logistical considerations. The ability of the Holders to realize upon the Collateral may be subject to certain bankruptcy law limitations in the event of a bankruptcy. See "—Certain Bankruptcy and Other Limitations."

The Company is permitted to form new Restricted Subsidiaries and, subject to certain restrictions in the Indenture and the Credit Agreement, to transfer all or a portion of the Collateral to one or more of its Restricted Subsidiaries;provided, that each such new Restricted Subsidiary will be required to execute a Guarantee in respect of the Company's obligations under the Notes and the Indenture and a supplement to the Security Agreement granting to the Collateral Agent a security interest in all of the assets of such Restricted Subsidiary on the same basis and subject to the same limitations as described in this section. See "—Certain Covenants—Additional Subsidiary Guarantees."

So long as no Event of Default shall have occurred and be continuing, and subject to certain terms and conditions in the Indenture and the Collateral Agreements, each of the Company and the Guarantors will be entitled to receive all cash dividends, interest and other payments made upon or with respect to the equity interests of any of its Subsidiaries and to exercise any voting, consensual rights and other rights pertaining to such Collateral pledged by it. Upon the occurrence and during the continuance of an Event of Default upon notice from the Collateral Agent, and subject to the Intercreditor Agreement,

(a) all rights of the Company or such Guarantor, as the case may be, to exercise such voting, consensual rights, or other rights shall cease and all such rights shall become vested in the Collateral Agent, which, to the extent permitted by law, shall have the sole right to exercise such voting, consensual rights or other rights,

(b) all rights of the Company or such Guarantor, as the case may be, to receive cash dividends, interest and other payments made upon or with respect to the Collateral shall cease, and such cash dividends, interest and other payments shall be paid to the Collateral Agent, and

(c) the Collateral Agent may sell the Collateral or any part thereof in accordance with, and subject to the terms of, the Collateral Agreements.

All funds distributed under the Collateral Agreements and received by the Collateral Agent for the ratable benefit of the Holders shall be distributed by the Collateral Agent in accordance with the provisions of the Indenture.

The collateral release provisions of the Indenture permit the release of Collateral without substitution of collateral having at least equal value under certain circumstances, including asset sales or dispositions made in compliance with the Indenture.

The Company will be entitled to releases of assets (including Capital Stock of Restricted Subsidiaries) included in the Collateral from the Liens securing the Notes under any one or more of the following circumstances:

(1) to enable the Company to consummate asset sales or dispositions that are not Asset Sales or that are Asset Sales permitted under the covenant described below under the caption "—Certain Covenants—Limitation on Asset Sales;"

(2) to enable the Company to consummate mergers, consolidations or sales of assets that are permitted under the covenant described below under the caption "—Certain Covenants—Mergers, Consolidation and Sale of Assets;"

(3) if any Subsidiary that is a Guarantor is released from its Guarantee, that Subsidiary's assets will also be released;

(4) if the Company exercises its legal defeasance option or our covenant defeasance option as described below under the caption "—Legal Defeasance and Covenant Defeasance;" or

(5) upon satisfaction and discharge of the Indenture or payment in full of the principal of and premium, if any, accrued and unpaid interest and Additional Interest, if any, on the Notes and all other Obligations that are then due and payable.

Certain Bankruptcy and Other Limitations

The right of the Collateral Agent to repossess and dispose or otherwise exercise remedies in respect of the Collateral upon the occurrence of an Event of Default is likely to be significantly impaired by applicable bankruptcy law if a bankruptcy proceeding were to be commenced by or against the Company or any of its Domestic Restricted Subsidiaries prior to the Collateral Agent having repossessed and disposed of the Collateral or otherwise completed the exercise of its remedies with respect to the Collateral. Under the Bankruptcy Code, a secured creditor such as the Collateral Agent is prohibited from repossessing its security from a debtor in a bankruptcy case, or from disposing of security repossessed from such debtor, without obtaining relief from the automatic stay imposed by Section 362 for the Bankruptcy Code. Moreover, the Bankruptcy Code permits the debtor to continue to retain and to use collateral even though the debtor is in default under the applicable debt instruments;provided that, under the Bankruptcy Code, the secured creditor is given "adequate protection." The meaning of the term "adequate protection" may vary according to circumstances, but it is intended in general to protect the value of the secured creditor's interest in the collateral securing the obligations owed to it and may include cash payments or the granting of additional security, if and at such times as the bankruptcy court in its discretion determines, for any diminution in the value of such collateral as a result of the stay of repossession or disposition or any use of the collateral by the debtor during the pendency of the bankruptcy case. In view of the lack of a precise definition of the term "adequate protection" and the broad discretionary powers of a bankruptcy court, it is impossible to predict how long payments under the Notes could be delayed following commencement of a bankruptcy case, whether or when the Collateral Agent could repossess or dispose of the Collateral or whether or to what extent Holders would be compensated for any delay in payment or loss of value of the Collateral through the requirement of "adequate protection."

Moreover, the Collateral Agent may need to evaluate the impact of the potential liabilities before determining to foreclose on Collateral consisting of real property because a secured creditor that holds a lien on real property may be held liable under environmental laws for the costs of remediating or preventing release or threatened releases of hazardous substances at such real property. Consequently, the Collateral Agent may decline to foreclose on such Collateral or exercise remedies available if it does not receive indemnification to its satisfaction from the Holders.

In addition, because a portion of the Collateral consists of pledges of a portion of the Capital Stock of certain of our Foreign Subsidiaries, the validity of those pledges under applicable foreign law, and the ability of the Holders to realize upon that Collateral under applicable foreign law, to the extent applicable, may be limited by such law, which limitations may or may not affect such Liens.

The Collateral Agent's ability to foreclose on the Collateral may be subject to lack of perfection, the consent of third parties, prior liens and practical problems associated with the realization of the Collateral Agent's Lien on the Collateral. See "Risk Factors—Risks Related to this Offering—The

proceeds from the collateral securing the notes may not be sufficient to pay all amounts owed under the notes if an event of default occurs and your right to receive payments under the notes will effectively be subordinated to payments under our senior revolving credit facility to the extent of the value of the assets securing that indebtedness."

Guarantees

The full and prompt payment of the Company's payment obligations under the Notes and the Indenture will be guaranteed, jointly and severally, by all present and future, direct and indirect, Domestic Restricted Subsidiaries. Each Guarantor will fully and unconditionally guarantee on a senior secured basis (each a "Guarantee" and, collectively, the "Guarantees"), jointly and severally, to each Holder and the Trustee, the full and prompt performance of the Company's Obligations under the Indenture and the Notes, including the payment of principal of, interest on, premium, if any, on and Additional Interest, if any, on the Notes. The Guarantee of each Guarantor will rank senior in right of payment to all existing and future subordinated Indebtedness of such Guarantor and equally in right of payment with all other existing and future senior Indebtedness of such Guarantor. The obligations of each Guarantor will be limited to the maximum amount which, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee or pursuant to its contribution obligations under the Indenture, will result in the obligations of such Guarantor under the Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law. The net worth of any Guarantor for such purpose shall include any claim of such Guarantor against the Company for reimbursement and any claim against any other Guarantor for contribution. Each Guarantor may consolidate with or merge into or sell its assets, including Capital Stock of Restricted Subsidiaries, to the Company or another Guarantor without limitation. See "—Certain Covenants—Mergers, Consolidation and Sale of Assets" and "—Limitation on Asset Sales."

A Guarantor will be released from its Guarantee without any action required on the part of the Trustee or any Holder:

(1) if (a) all of the Capital Stock issued by such Guarantor or all or substantially all of the assets of such Guarantor are sold or otherwise disposed of (including by way of merger or consolidation) to a Person other than the Company or any of its Domestic Restricted Subsidiaries or (b) such Guarantor ceases to be a Restricted Subsidiary, and the Company otherwise complies, to the extent applicable, with the covenant described below under "—Certain Covenants—Limitation on Asset Sales;"

(2) if the Company designates such Guarantor as an Unrestricted Subsidiary in accordance with the covenant described below under "—Certain Covenants—Limitation on Restricted Payments;"

(3) if the Company exercises the legal defeasance option or its covenant defeasance option as described below under "—Legal Defeasance and Covenant Defeasance;" or

(4) upon satisfaction and discharge of the Indenture or payment in full of the principal of premium, if any, accrued and unpaid interest and Additional Interest, if any, on the Notes and all other Obligations that are then due and payable.

At the Company's request and expense, the Trustee will execute and deliver an instrument evidencing such release. A Guarantor may also be released from its obligations under its Guarantee in connection with a permitted amendment of the Indenture. See "—Modification of the Indenture."

As of the date of the Indenture, all of our Subsidiaries will be Restricted Subsidiaries. However, under certain circumstances described below under the subheading "—Certain Covenants—Limitation

on Restricted Payments," the Company will be permitted to designate certain of its Subsidiaries as Unrestricted Subsidiaries. Unrestricted Subsidiaries will not be subject to the restrictive covenants of the Indenture and will not guarantee the Notes. Also, as of the date of the Indenture, none of the Company's Foreign Subsidiaries will guarantee the Notes. The Notes will be structurally subordinated to all of the existing and future liabilities of our Subsidiaries that do not guarantee the Notes.

Optional Redemption

Except as described below, the Notes are not redeemable before December 1, 2008. On or after December 1, 2008, the Company may redeem the Notes, at its option, in whole or in part, upon not less than 30 nor more than 60 days' notice, at the following redemption prices (expressed as percentages of the principal amount thereof) if redeemed during the twelve-month period commencing on December 1 of the year set forth below:

Year	Percentage
2008	104.500	%
2009	102.250	%
2010 and thereafter	100.000	%

In addition, the Company must pay accrued and unpaid interest and Additional Interest, if any, on the Notes redeemed to the date of redemption (subject to the right of the Holders of the relevant record date to receive interest due on the relevant interest payment date).

In addition, at any time, or from time to time, until December 1, 2007, the Company may, at its option, use an amount not to exceed the net cash proceeds of one or more Equity Offerings to redeem up to 35% of the aggregate principal amount of the Notes (which includes Additional Notes, if any) originally issued under the Indenture at a redemption price of 109% of the aggregate principal amount thereof, plus accrued and unpaid interest and Additional Interest, thereon, if any, to the date of redemption;provided that:

(1) at least 65% of the original principal amount of Notes (which includes Additional Notes, if any) issued under the Indenture remains outstanding immediately after any such redemption; and

(2) the Company makes such redemption not more than 120 days after the consummation of any such Equity Offering.

Selection and Notice of Redemption

In the event that the Company chooses to redeem less than all of the Notes, selection of the Notes for redemption will be made by the Trustee either:

(1) in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed; or

(2) if the Notes are not then listed on a national securities exchange, on apro rata basis, by lot or by such method as the Trustee may reasonably determine is fair and appropriate.

If a partial redemption is made with the proceeds of an Equity Offering, the Trustee will select the Notes only on apro rata basis or on as nearly apro rata basis as is practicable (subject to DTC procedures), unless such method is otherwise prohibited. No Notes of a principal amount of $1,000 or less shall be redeemed in part and Notes of a principal amount in excess of $1,000 may be redeemed in part in multiples of $1,000 only.

Notice of redemption will be mailed by first-class mail at least 30 but not more than 60 days before the redemption date to each Holder to be redeemed at its registered address. If Notes are to be

redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed. A new Note in a principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note (or appropriate adjustments to the amount and beneficial interests in the Global Note will be made).

The Company will pay the redemption price for any Note together with accrued and unpaid interest and Additional Interest, if any, thereon to the date of redemption. On and after the redemption date, interest will cease to accrue on Notes or portions thereof called for redemption as long as the Company has deposited with the paying agent funds in satisfaction of the applicable redemption price pursuant to the Indenture.

Mandatory Redemption; Offers to Purchase; Open Market Purchases

The Company is not required to make any mandatory redemption or sinking fund payments with respect to the Notes. However, under certain circumstances, the Company may be required to offer to purchase the Notes as described under the captions "—Repurchase upon Change of Control" and "—Certain Covenants—Limitation on Asset Sales." The Company may at any time and from time to time purchase Notes in the open market or otherwise.

Repurchase upon Change of Control

Upon the occurrence of a Change of Control, the Company will be required to offer to purchase all or a portion (in integral multiples of $1,000) of each Holder's Notes pursuant to the offer described below (the "Change of Control Offer"), at a purchase price in cash equal to 101% of the principal amount thereof on the date of purchase, plus accrued and unpaid interest and Additional Interest, if any, to the date of purchase.

Within 30 days following the date upon which the Change of Control occurred, the Company must send, by registered first-class mail, an offer to each Holder with a copy to the Trustee. Such offer shall state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is mailed, other than as may be required by law (the "Change of Control Payment Date").

Holders electing to have a Note purchased pursuant to a Change of Control Offer will be required to surrender the Note, with the form entitled "Option of Holder to Elect Purchase" on the reverse of the Note completed, to the paying agent at the address specified in the notice prior to the close of business on the third business day prior to the Change of Control Payment Date. If only a portion of a Note is purchased pursuant to a Change of Control Offer, a new Note in a principal amount equal to the portion thereof not purchased will be issued in the name of the Holder thereof upon cancellation of the original Note (or appropriate adjustments to the amount and beneficial interests in a Global Note will be made). Notes (or portions thereof) purchased pursuant to a Change of Control Offer will be cancelled and cannot be reissued.

The Company will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

If a Change of Control Offer is made, there can be no assurance that the Company will have available funds sufficient to pay the Change of Control purchase price for all the Notes that might be delivered by Holders seeking to accept the Change of Control Offer. If the Company is required to purchase outstanding Notes pursuant to a Change of Control Offer, the Company would be required to seek third-party financing to the extent it does not have available funds to meet its purchase

obligations. However, there can be no assurance that the Company would be able to obtain such financing on acceptable terms or at all, and the terms of the Credit Agreement, the Indenture or future debt and financing agreements may restrict the ability of the Company to obtain such financing.

Restrictions in the Indenture described herein on the ability of the Company and its Restricted Subsidiaries to incur additional Indebtedness, to grant Liens on its property, to make Restricted Payments and to make Asset Sales may also make more difficult or discourage a takeover of the Company, whether favored or opposed by the management or the Board of Directors of the Company. Such restrictions and the restrictions on transactions with Affiliates may, in certain circumstances, make more difficult or discourage any leveraged buyout of the Company or any of its Subsidiaries by the management of the Company. While such restrictions cover a wide variety of arrangements that have traditionally been used to effect highly leveraged transactions, the Indenture may not afford the Holders protection in all circumstances from the adverse aspects of a highly leveraged transaction, reorganization, restructuring, merger, recapitalization or similar transaction.

One of the events that constitutes a Change of Control under the Indenture is the disposition of "all or substantially all" of the Company's assets under certain circumstances. This term has not been interpreted under New York law (which is the governing law of the Indenture) to represent a specific quantitative test. As a consequence, there can be no assurance as to how a court interpreting New York law would interpret the phrase.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the "Change of Control" provisions of the Indenture, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the "Change of Control" provisions of the Indenture by virtue thereof.

Certain Covenants

The Indenture will contain, among others, the following covenants:

Limitation on Incurrence of Additional Indebtedness. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume, guarantee, acquire, become liable, contingently or otherwise, with respect to, or otherwise become responsible for payment of (collectively, "incur") any Indebtedness (other than Permitted Indebtedness). Notwithstanding the foregoing the Company and the Guarantors may incur Indebtedness (including Acquired Indebtedness) if on the date of (after giving effect to) the incurrence of such Indebtedness:

(i) no Default or Event of Default shall have occurred and be continuing; and

(ii) the Consolidated Fixed Charge Coverage Ratio of the Company will be at least 2.0 to 1.0.

Limitation on Restricted Payments. The Company will not, and will not cause or permit any of its Restricted Subsidiaries to, directly or indirectly:

(1) declare or pay any dividend or make any distribution (other than dividends or distributions payable (i) in Qualified Capital Stock of the Company or (ii) to the Company or a Guarantor) on or in respect of shares of Capital Stock of the Company or its Restricted Subsidiaries;

(2) purchase, redeem or otherwise acquire or retire for value any Capital Stock of the Company, any Restricted Subsidiary or any Affiliate of the Company (other than any such Capital Stock owned by the Company or any Guarantor);

(3) make any principal payment on, purchase, defease, redeem, prepay or otherwise acquire or retire for value, prior to any scheduled final maturity, scheduled repayment or scheduled sinking fund payment, any Indebtedness of the Company or any Guarantor that is subordinate or junior in right of payment to the Notes or a Guarantee; or

(4) make any Investment (other than Permitted Investments);

(each of the foregoing actions set forth in clauses (1), (2), (3) and (4) being referred to as a "Restricted Payment"), if at the time of such Restricted Payment or immediately after giving effect thereto:

(i) a Default or an Event of Default shall have occurred and be continuing;

(ii) the Company is not permitted to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) pursuant to the covenant described under "—Limitation on Incurrence of Additional Indebtedness;" or

(iii) the aggregate amount of Restricted Payments (including such proposed Restricted Payment) made subsequent to the Issue Date (the amount expended for such purposes, if other than in cash, being the Fair Market Value of such property at the time of the making thereof) shall exceed the sum of:

(A) 50% of the cumulative Consolidated Net Income (or if cumulative Consolidated Net Income is a loss, minus 100% of such loss) of the Company during the period beginning on the first day of the first fiscal quarter after the Issue Date and ending on the last day of the Company's most recent fiscal quarter ending prior to the date of such Restricted Payment for which financial statements are available (the "Reference Date") (treating such period as a single accounting period);plus

(B) 100% of the aggregate net cash proceeds received by the Company from any Person (other than a Subsidiary of the Company) from the issuance and sale subsequent to the Issue Date and on or prior to the Reference Date of Qualified Capital Stock of the Company (which shall include capital contributions to the Company) (excluding any net proceeds from an Equity Offering to the extent used to redeem Notes pursuant to the provisions described under "Redemption—Optional Redemption Upon Equity Offerings");plus

(C) 100% of the aggregate net cash proceeds received from the issuance of Indebtedness or shares of Disqualified Capital Stock of the Company (other than to a Subsidiary of the Company) that have been converted into or exchanged for Qualified Capital Stock of the Company subsequent to the Issue Date and on or prior to the Reference Date;plus

(D) the net reduction in the Investments (other than Permitted Investments) treated as a Restricted Payment previously made by the Company or any Restricted Subsidiary in any Person (other than a Restricted Subsidiary) to the extent such reduction results from net proceeds received by the Company and its Restricted Subsidiaries upon the (x) repurchase, repayment or redemption of such Investments by such Person (but only to the extent constituting return of capital) and (y) the sale of such Investment (but only to the extent such sale does not increase Consolidated Net Income of the Company), in each case, in an amount not exceeding the aggregate amount of such Investments;plus

(E) (1) the Company's portion (proportionate to the Company's equity interest in such Subsidiary) of the fair market value of the net assets of any Unrestricted Subsidiary at the time such Unrestricted Subsidiary is designated a Restricted Subsidiary in an amount not to exceed the amount of Investments (excluding Permitted Investments) previously made (and treated as a Restricted Payment) by the Company of any or its Restricted Subsidiaries in such Unrestricted Subsidiary and (2) the aggregate amount of cash dividends or cash distributions

received by the Company or the Guarantors from an Unrestricted Subsidiary from the Issue Date to the Reference Date.

In the case of clause (iii)(B) above, any net cash proceeds from issuances and sales of Qualified Capital Stock of the Company financed directly or indirectly using funds borrowed from the Company or any Subsidiary of the Company, shall be excluded until and to the extent such borrowing is repaid.

The provisions set forth in the immediately preceding paragraph do not prohibit:

(1) the payment of any dividend or other distribution or redemption within 60 days after the date of declaration of such dividend or call for redemption if such payment would have been permitted on the date of declaration or call for redemption;

(2) the acquisition of any shares of Qualified Capital Stock of the Company, solely in exchange for other shares of Qualified Capital Stock of the Company;

(3) the acquisition of any Indebtedness of the Company or the Guarantors that is subordinate or junior in right of payment to the Notes and Guarantees or the acquisition of Disqualified Capital Stock either (i) solely in exchange for shares of Qualified Capital Stock of the Company, or (ii) through the application of net proceeds of a sale for cash (other than to a Subsidiary of the Company) within 60 days after such sale if no Default or Event of Default would exist after giving effect thereto, of Refinancing Indebtedness;

(4) an Investment either (i) solely in exchange for shares of Qualified Capital Stock of the Company or (ii) through the application of the net proceeds of a sale for cash (other than to a Subsidiary of the Company) of shares of Qualified Capital Stock of the Company within 60 days after such sale;

(5) in the event of a Change of Control, and if no Default shall have occurred and be continuing or would exist after giving effect thereto, the payment, purchase, redemption, defeasance, satisfaction, discharge or other acquisition or retirement of Indebtedness that is subordinated to the Notes or the Guarantees, in each case, at a purchase price not greater than 101% of the principal amount of such Indebtedness (or, if such Indebtedness was issued with original issue discount, 101% of the accreted value), plus any accrued and unpaid interest thereon;provided, however, that prior to such payment, purchase, redemption, defeasance, satisfaction, discharge or other acquisition or retirement, the Company has made a Change of Control Offer with respect to the Notes as a result of such Change of Control and has repurchased all Notes validly tendered and not withdrawn in connection with such Change of Control Offer;

(6) (i) general corporate overhead expenses of Holdings, including, without limitation, franchise taxes and other fees required to maintain the existence of Holdings, insurance premiums and indemnification claims made by directors or officers of Holdings attributable to the ownership or operation of the Company and its Subsidiaries and (ii) reasonable fees and expenses paid to members of the board of directors of Holdings;provided, that such fees and expenses described in this clause (ii) are in an aggregate amount not to exceed $500,000 in any fiscal year;

(7) the application of the proceeds from the issuance of the Notes on the Issue Date as described under the "Use of Proceeds" section of this prospectus;

(8) advances to any direct or indirect parent entity of the Company to be used by such entity solely to pay federal, state and local income taxes made no earlier than five days prior to the date on which such entity is required to make such payment in an amount not to exceed the aggregate tax liability of the Company and its Restricted Subsidiaries for such calendar year determined as if the Company and its Restricted Subsidiaries were a separate affiliated group (as defined in Section 1504 of the Internal Revenue Code of 1986, as amended) filing a consolidated return, or,

to the extent applicable, a separate group filing combined or unitary returns, and then only to the extent that any such payments are actually paid by such entity to governmental entities;

(9) if no Default or Event of Default has occurred and is continuing or would exist after giving effect thereto, the purchase, repurchase, redemption or other acquisition of Capital Stock of the Company from employees, former employees, directors, or former directors of the Company (or permitted transferees of such employees, former employees, directors or former directors), pursuant to the terms of the agreements (including employment agreements) or plans (or amendments thereto) approved by the Board of Directors of the Company under which such individuals purchase or sell, or are granted the option to purchase or sell, shares of such Capital Stock;provided, that the aggregate amount of such repurchases and other acquisitions in any calendar year shall not exceed $500,000;

(10) if no Default or Event of Default has occurred and is continuing or would exist after giving effect thereto, the payment of the consulting fee pursuant to the Management Agreement;provided, that the aggregate amount of such fee in any calendar year shall not exceed $1.0 million; and

(11) if no Default or Event of Default shall have occurred and be continuing or would exist after giving effect thereto, other Restricted Payments not to exceed $10.0 million in the aggregate since the Issue Date.

In determining the aggregate amount of Restricted Payments made subsequent to the Issue Date in accordance with clause (iii) of the first paragraph of this "Limitation on Restricted Payments" covenant amounts expended pursuant to clauses (1), (4)(ii) and (9) shall be included in such calculation and amounts expended pursuant to clauses (2), (3), 4(i), (5), (6), (7), (8), (10) and (11) shall not be included in such calculation.

Not later than the date of making any Restricted Payment, the Company shall deliver to the Trustee an Officers' Certificate stating that such Restricted Payment complies with the Indenture and setting forth in reasonable detail the basis upon which the required calculations were computed, which calculations may be based upon the Company's latest available internal quarterly financial statements.

Limitation on Asset Sales. The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(1) the Company or the applicable Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the assets sold or otherwise disposed;

(2) at least 75% of the consideration received by the Company or the Restricted Subsidiary, as the case may be, from such Asset Sale is in the form of cash or Cash Equivalents received substantially concurrent with the time of such disposition;provided that the amount of any liabilities (as shown on the most recent applicable balance sheet) of the Company or such Restricted Subsidiary (other than liabilities that are by their terms subordinated to the Notes) that are assumed by the transferee of any such assets shall be deemed to be cash for purposes of this provision if the documents governing such liabilities provide that there is no further recourse to the Company or any of its Subsidiaries with respect to such liabilities; and

(3) the Company shall apply, or cause such Restricted Subsidiary to apply, the Net Cash Proceeds relating to such Asset Sale within 360 days of receipt thereof either:

(a) to repay any outstanding Indebtedness under the Credit Agreement and correspondingly reduce the commitments thereunder;

(b) to reinvest in property, plant, equipment or other long-term assets that replace the properties and assets that were the subject of such Asset Sale or that will be used or useful in the Permitted Business (including expenditures for maintenance, repair or improvement of existing properties and assets); or

Pending the final application of Net Cash Proceeds, the Company may temporarily reduce revolving credit borrowings or invest such Net Cash Proceeds in Cash Equivalents. On the 361^st day after an Asset Sale or such earlier date, if any, as the Board of Directors of the Company or of such Restricted Subsidiary determines not to apply the Net Cash Proceeds relating to such Asset Sale as set forth in clauses (3)(a), 3(b) or 3(c) of the preceding paragraph (each, a "Net Proceeds Offer Trigger Date"), such aggregate amount of Net Cash Proceeds which have not been applied (each a "Net Proceeds Offer Amount") shall be applied by the Company or such Restricted Subsidiary to make an offer to purchase (the "Net Proceeds Offer") on a date (the "Net Proceeds Offer Payment Date") not less than 30 nor more than 45 days following the applicable Net Proceeds Offer Trigger Date, from all Holders of the Notes the maximum principal amount of Notes that may be purchased with the Net Proceeds Offer Amount at a price equal to 100% of the principal amount thereof, plus accrued and unpaid interest and Additional Interest thereon, if any, to the date of purchase.

If at any time any consideration other than cash and Cash Equivalents received by the Company or any Restricted Subsidiary, as the case may be, in connection with any Asset Sale is converted into or sold or otherwise disposed of for cash or Cash Equivalents (other than interest received with respect to any such non-cash consideration), then such conversion or disposition shall be deemed to be an Asset Sale on the date of such conversion or disposition, as the case may be, and the Net Cash Proceeds thereof shall be applied in accordance with this covenant.

The Company may defer any Net Proceeds Offer until there is an aggregate unutilized Net Proceeds Offer Amount equal to or in excess of $5.0 million resulting from one or more Asset Sales in which case the accumulation of such amount shall constitute a Net Proceeds Offer Trigger Date (at which time, the entire unutilized Net Proceeds Offer Amount, and not just the amount in excess of $5.0 million, shall be applied as required pursuant to this covenant). If any of the Net Cash Proceeds Amount remains after consummation of a Net Proceeds Offer, the Company may use such amount for any corporate purpose to the extent not otherwise prohibited by the Indenture and the Net Proceeds Offer Amount will be reset at zero.

In the event of the transfer of substantially all (but not all) of the property and assets of the Company and its Restricted Subsidiaries as an entirety to a Person in a transaction permitted under "—Merger, Consolidation and Sale of Assets" that does not constitute a Change of Control, the successor entity shall be deemed to have sold the properties and assets of the Company and its Restricted Subsidiaries not so transferred for purposes of this covenant, and shall comply with the provisions of this covenant with respect to such deemed sale as if it constituted an Asset Sale. The Fair Market Value of such properties and assets of the Company or its Restricted Subsidiaries deemed to be sold shall be deemed to be Net Cash Proceeds for purposes of this covenant.

Each notice of a Net Proceeds Offer shall be mailed first class, postage prepaid, to the record Holders as shown on the register of Holders within 20 days following the Net Proceeds Offer Trigger Date, with a copy to the Trustee. Upon receiving notice of the Net Proceeds Offer, Holders may elect to tender their Notes in whole or in part in integral multiples of $1,000 in exchange for cash. To the extent Holders properly tender Notes in an amount exceeding the Net Proceeds Offer Amount, Notes of tendering Holders will be purchased on apro rata basis (based on amounts tendered). A Net Proceeds Offer shall remain open for a period of 20 business days or such longer period as may be required by law.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any securities laws or regulations conflict with the "Asset Sale" provisions of the Indenture, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the "Asset Sale" provisions of the Indenture by virtue of such compliance.

Limitation on Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries. The Company will not, and will not cause or permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or permit to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary to:

(1) pay dividends or make any other distributions on or in respect of its Capital Stock;

(2) make loans or advances or to pay any Indebtedness or other obligation owed to the Company or any other Restricted Subsidiary; or

(3) transfer any of its property or assets to the Company or any other Restricted Subsidiary, except for such encumbrances or restrictions existing:

(a) under applicable law, rule, regulation, order, license or permit;

(b) under the Indenture and the Collateral Agreements;

(c) by reason of customary non-assignment provisions of any lease of any Restricted Subsidiary to the extent such provisions restrict the transfer of the lease or the property leased thereunder;

(d) under any instrument governing Acquired Indebtedness, which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person or the properties or assets of the Person so acquired;

(e) under the Credit Agreement;

(f) by reason of restrictions on the transfer of assets subject to any Permitted Lien;

(g) under customary agreements to sell assets or Capital Stock permitted to be sold under the Indenture pending the closing of such sale;

(h) under Purchase Money Indebtedness or Capitalized Lease Obligations permitted under the Indenture;provided, that such encumbrances and restrictions relate only to the assets financed with such Indebtedness;

(i) by reason of restrictions on cash or other deposits under bona fide arrangements with customers entered into in the ordinary course of business, consistent with past practice;

(j) on any Foreign Restricted Subsidiary under Indebtedness of such Subsidiary permitted under the Indenture; or

(k) under Refinancing Indebtedness incurred to Refinance the Indebtedness referred to in clause (b), (d) or (e);provided, that the provisions relating to such encumbrance or restriction contained in any such Indebtedness are no more adverse to the Holders and no less favorable or more onerous to the Company and its Restricted Subsidiaries than the provisions relating to such encumbrance or restriction contained in agreements referred to in the Indebtedness being Refinanced.

Limitation on Issuances and Sales of Capital Stock of Subsidiaries. The Company will not, and will not permit or cause any of its Restricted Subsidiaries to, transfer, convey, issue or sell any Capital

Stock of any Restricted Subsidiary to any Person (other than to the Company or to a Wholly Owned Subsidiary and directors' qualifying shares);provided, that this provision shall not prohibit:

(1) any transfer, issuance or sale if, immediately after giving effect thereto, such Restricted Subsidiary would no longer constitute a Restricted Subsidiary and any Investment in such Person remaining after giving effect to such issuance or sale would have been permitted to be made under the "—Limitations on Restricted Payments" covenant if made on the date of such issuance or sale or

(2) the sale of all of the Capital Stock of a Restricted Subsidiary in compliance with the provisions of the "—Limitations on Asset Sales" covenant.

Limitation on Liens. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or otherwise cause or suffer to exist any Liens (other than Permitted Liens) of any kind against or upon any property or assets of the Company or any of its Restricted Subsidiaries whether owned on the Issue Date or acquired after the Issue Date, or any proceeds therefrom, or assign or otherwise convey any right to receive income or profits therefrom.

Merger, Consolidation and Sale of Assets. The Company will not, in a single transaction or series of related transactions, consolidate or merge with or into any Person, or sell, assign, transfer, lease, convey or otherwise dispose of (or cause or permit any Restricted Subsidiary to sell, assign, transfer, lease, convey or otherwise dispose of) all or substantially all of the Company's assets (determined on a consolidated basis for the Company and its Restricted Subsidiaries) whether as an entirety or substantially as an entirety to any Person unless:

(1) either:

(a) the Company shall be the surviving or continuing corporation; or

(b) the Person (if other than the Company) formed by such consolidation or into which the Company is merged or the Person which acquires by sale, assignment, transfer, lease, conveyance or other disposition the properties and assets of the Company and of the Company's Restricted Subsidiaries substantially as an entirety (the "Surviving Entity"):

(x) shall be an entity organized and validly existing under the laws of the United States or any State thereof or the District of Columbia; and

(y) shall expressly assume (i) by supplemental indenture (in form and substance reasonably satisfactory to the Trustee), executed and delivered to the Trustee, the due and punctual payment of the principal of, and premium, if any, interest and Additional Interest, if any, on all of the Notes and the performance of every covenant of the Notes, the Indenture and the Registration Rights Agreement on the part of the Company to be performed or observed thereunder and (ii) by amendment, supplement or other instrument (in form and substance reasonably satisfactory to the Trustee and the Collateral Agent), executed and delivered to the Trustee, all obligations of the Company under the Collateral Agreements, and in connection therewith shall cause such instruments to be filed and recorded in such jurisdictions and take such other actions as may be required by applicable law to perfect or continue the perfection of the Lien created under the Collateral Agreements on the Collateral owned by or transferred to the surviving entity;

(2) immediately after giving effect to such transaction and the assumption contemplated by clause (1)(b)(y) above (including giving effect to any Indebtedness and Acquired Indebtedness incurred or anticipated to be incurred in connection with or in respect of such transaction), (a) the Company or such Surviving Entity, as the case may be, is able to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) in compliance with the covenant described

under"—Limitation on Incurrence of Additional Indebtedness" and (b) no Default or Event of Default shall have occurred or be continuing; and

(3) the Company or the Surviving Entity shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture comply with the applicable provisions of the Indenture and that all conditions precedent in the Indenture relating to such transaction have been satisfied.

For purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise, in a single transaction or series of transactions) of all or substantially all of the properties or assets of one or more Restricted Subsidiaries of the Company, the Capital Stock of which constitutes all or substantially all of the properties and assets of the Company, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company.

Upon any consolidation, combination or merger or any transfer of all or substantially all of the assets of the Company in accordance with the foregoing, in which the Company is not surviving or the continuing corporation, the successor Person formed by such consolidation or into which the Company is merged or to which such conveyance, lease or transfer is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under the Indenture and the Notes with the same effect as if such surviving entity had been named as such. Upon such substitution, the Company and any Guarantors that remain Subsidiaries of the Company shall be released and discharged from their obligations under the Indenture and the Guarantees.

Each Guarantor will not, and the Company will not cause or permit any Guarantor to, consolidate with or merge with or into any Person, other than the Company or any other Guarantor unless:

(1) the entity formed by or surviving any such consolidation or merger (if other than the Guarantor) or to which such sale, lease, conveyance or other disposition shall have been made is a corporation organized and existing under the laws of the United States or any State thereof or the District of Columbia;

(2) such entity assumes (a) by supplemental indenture (in form and substance reasonably satisfactory to the Trustee), executed and delivered to the Trustee, all of the obligations of the Guarantor under the Guarantee and the performance of every covenant of the Guarantee, the Indenture and the Registration Rights Agreement and (b) by amendment, supplement or other instrument (in form and substance satisfactory to the Trustee and the Collateral Agent) executed and delivered to the Trustee and the Collateral Agent, all obligations of the Guarantor under the Collateral Agreements and in connection therewith shall cause such instruments to be filed and recorded in such jurisdictions and take such other actions as may be required by applicable law to perfect or continue the perfection of the Lien created under the Collateral Agreements on the Collateral owned by or transferred to the surviving entity; and

(3) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing.

Limitations on Transactions with Affiliates. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into or permit to exist any transaction or series of related transactions (including, without limitation, the purchase, sale, lease or exchange of any property or the rendering of any service) with, or for the benefit of, any of its Affiliates (each an "Affiliate Transaction"), other than:

(x) Permitted Affiliate Transactions, and

(y) Affiliate Transactions on terms that are no less favorable than those that might reasonably have been obtained in a comparable transaction at such time on an arm's-length basis from a Person that is not an Affiliate of the Company or such Restricted Subsidiary.

With respect to all Affiliate Transactions (other than Permitted Affiliated Transactions):

(i) the Company will deliver an Officers' Certificate to the Trustee certifying that such transactions are in compliance with clause (y) of the preceding paragraph;

(ii) if such Affiliate Transaction involves aggregate payments or other property with a Fair Market Value in excess of $2.5 million shall be approved by a majority of the members of the Board of Directors of the Company (including a majority of the disinterested members thereof), as the case may be, such approval to be evidenced by a Board Resolution stating that such Board of Directors has determined that such transaction complies with the foregoing provisions; and

(iii) if such Affiliate Transaction involves an aggregate Fair Market Value of more than $5.0 million, the Company will, prior to the consummation thereof, obtain a favorable opinion as to the fairness of the financial terms of such transaction or series of related transactions to the Company or the relevant Restricted Subsidiary, as the case may be, from an Independent Financial Advisor and file the same with the Trustee.

The restrictions set forth in the first paragraph of this covenant will not apply to the following transactions (collectively, "Permitted Affiliate Transactions"):

(1) reasonable fees and compensation paid to and indemnity provided on behalf of, officers, directors, employees or consultants of the Company or any Restricted Subsidiary;

(2) transactions exclusively between or among the Company and any of its Wholly Owned Restricted Subsidiaries or exclusively between or among such Wholly Owned Restricted Subsidiaries,provided, that such transactions are not otherwise prohibited by the Indenture;

(3) any agreement as in effect as of the Issue Date or any transaction contemplated thereby and any amendment thereto or any replacement agreement thereto so long as any such amendment or replacement agreement is not more disadvantageous to the Holders, the Company or the Restricted Subsidiaries in all material respects than the original agreement as in effect on the Issue Date;

(4) Restricted Payments permitted by the Indenture or Permitted Investments;

(5) any merger or other transaction with an Affiliate solely for the purpose of reincorporating the Company in another jurisdiction or creating a holding company of the Company;

(6) any employment, stock option, stock repurchase, employee benefit compensation, business expense reimbursement, severance, termination or other employment-related agreements, arrangements or plans entered into in good faith by the Company or any of its Restricted Subsidiaries in the ordinary course of business;

(7) sales or purchases of inventory, other products or services to or from any Affiliate of the Company entered into in the ordinary course of business on terms no less favorable to the Company and its Subsidiaries than those that could be obtained at the time of such sale or purchase in arm's-length dealings with a Person who is not an Affiliate; and

(8) any agreement existing and as in effect on the Issue Date, including the Management Agreement.

Additional Subsidiary Guarantees. If the Company or any of its Restricted Subsidiaries acquires or creates another Domestic Restricted Subsidiary after the Issue Date (other than an Unrestricted Subsidiary), then the Company shall cause such Domestic Restricted Subsidiary to:

(1) execute and deliver to the Trustee a supplemental indenture in form reasonably satisfactory to the Trustee pursuant to which such Subsidiary shall unconditionally guarantee on a senior secured basis all of the Company's obligations under the Notes and the Indenture on the terms set forth in the Indenture;

(2) execute and deliver to the Collateral Agent such amendments to the Collateral Agreements as the Collateral Agent deems necessary or advisable in order to grant to the Collateral Agent, for the benefit of the Holders, a perfected security interest in the Capital Stock of such new Domestic Restricted Subsidiary and any debt securities of such new Subsidiary, subject to the Permitted Liens, which are owned by the Company or Subsidiary and required to be pledged pursuant to the Security Agreement, (b) deliver to the Collateral Agent any certificates representing such Capital Stock and debt securities, together with (i) in the case of such Capital Stock, undated stock powers or instruments of transfer, as applicable, endorsed in blank, and (ii) in the case of such debt securities, endorsed in blank, in each case executed and delivered by an Officer of the Company or such Subsidiary, as the case may be;

(3) take such actions as are necessary or as the Collateral Agent reasonably determines to be advisable to grant to the Collateral Agent for the benefit of the Holders a perfected security interest in the assets of such new Domestic Restricted Subsidiary, subject to the Permitted Liens, including the filing of Uniform Commercial Code financing statements in such jurisdictions as may be required by the Security Agreement or by law or as may be reasonably requested by the Collateral Agent;

(4) take such further action and execute and deliver such other documents specified in the Indenture or otherwise reasonably requested by the Trustee or the Collateral Agent to effectuate the foregoing; and

(5) deliver to the Trustee an Opinion of Counsel that such supplemental indenture and any other documents required to be delivered have been duly authorized, executed and delivered by such Domestic Restricted Subsidiary and constitutes a legal, valid, binding and enforceable obligations of such Domestic Restricted Subsidiary and such other opinions regarding the perfection of such Liens in the assets of such Domestic Restricted Subsidiary as provided for in the Indenture.

Thereafter, such Subsidiary shall be a Guarantor for all purposes of the Indenture.

Impairment of Security Interest. Neither the Company nor any of its Restricted Subsidiaries will (a) take or omit to take any action which would adversely affect or impair in any material respect the Liens (other than the incurrence of Permitted Liens) in favor of the Collateral Agent with respect to the Collateral, (b) grant to any Person (other than the Collateral Agent), or permit any Person (other than the Collateral Agent), to retain any interest whatsoever in the Collateral other than Permitted Liens or (c) enter into any agreement that requires the proceeds received from any sale of Collateral to be applied to repay, redeem, defease or otherwise acquire or retire any Indebtedness of any Person, other than as permitted by the Indenture, the Notes and the Collateral Agreements. The Company shall, and shall cause each Guarantor to, at their sole cost and expense, (i) execute and deliver all such agreements and instruments as the Collateral Agent shall reasonably request to more fully or accurately describe the property intended to be Collateral or the obligations intended to be secured by the Collateral Agreements and (ii) file any such notice filings or other agreements or instruments as may be reasonably necessary or desirable under applicable law to perfect the Liens created by the Collateral Agreements at such times and at such places as the Collateral Agent may reasonably request.

Real Estate Mortgages and Filings. With respect to any fee interest in any real property (individually and collectively, the "Premises") (a) owned by the Company or a Domestic Restricted Subsidiary on the Issue Date (other than the Syracuse Facility) or (b) acquired by the Company or a Domestic Restricted Subsidiary after the Issue Date (other than real property located in the State of New York), (i) with a purchase price, or with a Fair Market Value as of the Issue Date, as applicable, greater than $500,000, and (ii) within 60 days of the Issue Date in the case of clause (a) or within 90 days of the acquisition thereof in the case of clause (b), the Company shall deliver to the Collateral Agent:

(1) as mortgagee, fully executed counterparts of Mortgages, each dated as of a date prior to the 60th day after the Issue Date or the date of acquisition of such property, as the case may be, duly executed by the Company or the applicable Domestic Restricted Subsidiary, together with evidence of the completion (or satisfactory arrangements for the completion), of all recordings and filings of such Mortgage as may be necessary to create a valid, perfected Lien, subject to Permitted Liens, against the properties purported to be covered thereby;

(2) mortgagee's title insurance policies in favor of the Collateral Agent, as mortgagee for the ratable benefit of the Collateral Agent, the Trustee and the Holders in an amount equal to 100% of the Fair Market Value of the Premises purported to be covered by the related Mortgage, insuring that title to such property is marketable and that the interests created by the Mortgage constitute valid Liens thereon free and clear of all Liens, defects and encumbrances other than Permitted Liens, and such policies shall also include, to the extent available, other customary endorsements and shall be accompanied by evidence of the payment in full of all premiums thereon; and

(3) with respect to each of the covered Premises, the most recent survey of such Premises, together with either (i) an updated survey certification in favor of the Trustee and the Collateral Agent from the applicable surveyor stating that, based on a visual inspection of the property and the knowledge of the surveyor, there has been no change in the facts depicted in the survey or (ii) an affidavit from the Company or the applicable Guarantor, as applicable, stating that there has been no change, other than, in each case, changes that do not materially adversely affect the use by the Company or Guarantor, as applicable, of such Premises for the Company or such Guarantor's business as so conducted, or intended to be conducted, at such Premises.

In the event that we or the Guarantors, as applicable, execute first-priority mortgages of the Syracuse Facility or any other existing and future owned real property in the State of New York under the Credit Agreement in the future, the Indenture provides that we must simultaneously execute second-priority mortgages of such real property in favor of the Collateral Agent for the benefit of the Holders of the Notes.

Leasehold Mortgages and Filings; Landlord Waivers. The Company and each of its Domestic Restricted Subsidiaries shall deliver Mortgages with respect to the Company's leasehold interests in the premises (the "Leased Premises") occupied by the Company or such Domestic Restricted Subsidiary pursuant to leases entered into after the Issue Date (collectively, the "Leases," and individually, a "Lease").

Prior to the effective date of any Lease, the Company and such Subsidiaries shall provide to the Trustee all of the items described in clauses (2) and (3) of "—Certain Covenants—Real Estate Mortgages and Filings" above and in addition shall use their respective reasonable commercial efforts to obtain an agreement executed by the lessor under the Lease, whereby the lessor consents to the Mortgage and waives or subordinates its landlord Lien (whether granted by the instrument creating the leasehold estate or by applicable law), if any, and which shall be entered into by the Collateral Agent.

Each of the Company and each of its Domestic Restricted Subsidiaries that is a lessee of, or becomes a lessee of, real property, is, and will be, required to use commercially reasonable efforts to deliver to the Collateral Agent a landlord waiver, substantially in the form of the exhibit form thereof to be attached to the Indenture, executed by the lessor of such real property;provided that in the case where such lease is a lease in existence on the Issue Date, the Company or its Domestic Restricted Subsidiary that is the lessee thereunder shall be required to use such commercially reasonable efforts to deliver within 90 days from the Issue Date.

Conduct of Business. The Company will not, and will not permit any of its Restricted Subsidiaries to, engage in any businesses other than Permitted Businesses.

(1) all quarterly and annual financial information that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if the Company were required to file such Forms, including a "Management's Discussion and Analysis of Financial Condition and Results of Operations" that describes the financial condition and results of operations of the Company and its consolidated Subsidiaries (showing in reasonable detail, either on the face of the financial statements or in the footnotes thereto and in "Management's Discussion and Analysis of Financial Condition and Results of Operations," the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company, if any) and, with respect to the annual information only, a report thereon by the Company's certified independent accountants; and

(2) all current reports that would be required to be filed with the SEC on Form 8-K if the Company were required to file such reports, in each case within the time periods specified in the SEC's rules and regulations.

Notwithstanding the foregoing, the Company may satisfy such requirements prior to the effectiveness of the registration statement contemplated by the Registration Rights Agreement by filing with the SEC such registration statement, to the extent that any such registration statement contains substantially the same information as would be required to be filed by the Company if it were subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, and by providing the Trustee and Holders with such Registration Statement (and any amendments thereto) promptly following the filing thereof.

In addition, following the consummation of the Exchange Offer, whether or not required by the rules and regulations of the SEC, the Company will file a copy of all such information and reports with the SEC for public availability within the time periods specified in the SEC's rules and regulations (unless the SEC will not accept such a filing). In addition, the Company has agreed that, prior to the consummation of the Exchange Offer, for so long as any Notes remain outstanding, it will furnish to the Holders upon their request, the information required to be delivered pursuant to Rule 144(A)(d)(4) under the Securities Act.

Payments for Consent. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the Indenture, the Notes, any Collateral Agreement or the Intercreditor Agreement unless such consideration is offered to be paid or is paid to all Holders that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

Events of Default

The following events are defined in the Indenture as "Events of Default":

(1) the failure to pay interest and Additional Interest, if any, on any Notes when the same becomes due and payable and the default continues for a period of 30 days;

(2) the failure to pay the principal of or premium, if any, on any Notes, when such principal becomes due and payable, at maturity, upon redemption or otherwise (including the failure to make a payment to purchase Notes tendered pursuant to a Change of Control Offer or a Net Proceeds Offer when such payments become due);

(3) a default in the observance or performance of any other covenant or agreement contained in the Indenture (other than the payment of the principal of, or premium, if any, or interest or Additional Interest, if any, on any Note) or any Collateral Agreement which default continues for a period of 30 days after the Company receives written notice specifying the default (and demanding that such default be remedied) from the Trustee or the Holders of at least 25% of the outstanding principal amount of the Notes (except in the case of a default with respect to the "—Certain Covenants—Merger, Consolidation and Sale of Assets" covenant, which will constitute an Event of Default with such notice requirement but without such passage of time requirement);

(4) the failure to pay at final maturity (giving effect to any applicable grace periods and any extensions thereof) the principal amount of any Indebtedness of the Company or any Restricted Subsidiary other than the Notes and Guarantees, or the acceleration of the final stated maturity of any such Indebtedness (which acceleration is not rescinded, annulled or otherwise cured within 20 days from the date of acceleration) if the aggregate principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness in default for failure to pay principal at final maturity or which has been accelerated (in each case with respect to which the 20-day period described above has elapsed), aggregates $5.0 million or more at any time;

(5) one or more judgments in an aggregate amount in excess of $5.0 million shall have been rendered against the Company or any of its Restricted Subsidiaries (other than any judgment as to which a reputable and solvent third party insurer has accepted full coverage) and such judgments remain undischarged, unpaid or unstayed for a period of 60 days after such judgment or judgments become final and non-appealable;

(6) certain events of bankruptcy affecting the Company or any of its Significant Subsidiaries;

(7) any Collateral Agreement at any time for any reason shall cease to be in full force and effect in all material respects, or ceases to give the Collateral Agent the Liens, rights, powers and privileges purported to be created thereby, superior to and prior to the rights of all third Persons other than the holders of Permitted Liens and subject to no other Liens except as expressly permitted by the applicable Collateral Agreement;

(8) the Company or any of the Guarantors, directly or indirectly, contest in any manner the effectiveness, validity, binding nature or enforceability of any Collateral Agreement; or

(9) any Guarantee of a Significant Subsidiary ceases to be in full force and effect or any Guarantee of a Significant Subsidiary is declared to be null and void and unenforceable or any Guarantee of a Significant Subsidiary is found to be invalid or any Guarantor denies its liability under its Guarantee (other than by reason of release of a Guarantor in accordance with the terms of the Indenture).

If an Event of Default (other than an Event of Default specified in clause (6) above with respect to the Company) shall occur and be continuing and has not been waived, the Trustee or the Holders of at least 25% in principal amount of outstanding Notes may declare the principal of and premium, if

any, accrued interest and Additional Interest, if any, on all the Notes to be due and payable by notice in writing to the Company and the Trustee specifying the Event of Default and that it is a "notice of acceleration" (the "Acceleration Notice"), and the same shall become immediately due and payable.

If an Event of Default specified in clause (6) above with respect to the Company occurs and is continuing, then all unpaid principal of, and premium, if any, and accrued and unpaid interest and Additional Interest, if any, on all of the outstanding Notes shallipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

At any time after a declaration of acceleration with respect to the Notes as described in the preceding paragraphs, the Holders of a majority in principal amount of the Notes may rescind and cancel such declaration and its consequences:

(1) if the rescission would not conflict with any judgment or decree;

(2) if all existing Events of Default have been cured or waived except nonpayment of principal, premium, if any, interest or Additional Interest, if any, that has become due solely because of the acceleration;

(3) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal and premium, if any, and Additional Interest, if any, which has become due otherwise than by such declaration of acceleration, has been paid;

(4) if the Company has paid the Trustee its reasonable compensation and reimbursed the Trustee for its reasonable expenses, disbursements and its advances; and

(5) in the event of the cure or waiver of an Event of Default of the type described in clause (7) of the description above of Events of Default, the Trustee shall have received an Officers' Certificate and an Opinion of Counsel that such Event of Default has been cured or waived.

No such rescission shall affect any subsequent Default or impair any right consequent thereto.

The Holders of a majority in principal amount of the Notes may waive any existing Default or Event of Default under the Indenture, and its consequences, except a default in the payment of the principal of or premium, if any, interest or Additional Interest, if any, on any Notes.

Holders may not enforce the Indenture or the Notes except as provided in the Indenture and under the TIA. Subject to the provisions of the Indenture relating to the duties of the Trustee, the Trustee is under no obligation to exercise any of its rights or powers under the Indenture at the request, order or direction of any of the Holders, unless such Holders have offered to the Trustee reasonable indemnity. Subject to the provisions of the Indenture and applicable law, the Holders of a majority in aggregate principal amount of the then outstanding Notes have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee.

No past, present or future director, officer, employee, incorporator, or stockholder of the Company or a Guarantor, as such, shall have any liability for any obligations of the Company or the Guarantors under the Notes, the Guarantees or the Indenture or for any claim based on, in respect of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

Under the Indenture, the Company is required to provide an Officers' Certificate to the Trustee promptly upon any Officer obtaining knowledge of any Default or Event of Default(provided that such Officers' Certificate shall be provided at least annually whether or not such Officers know of any Default or Event of Default) that has occurred and, if applicable, describe such Default or Event of Default and the status thereof.

Legal Defeasance and Covenant Defeasance

The Company may, at its option and at any time, elect to have its obligations and the obligations of the Guarantors discharged with respect to the outstanding Notes ("Legal Defeasance"). Such Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, except for:

(1) the rights of Holders to receive payments in respect of the principal of, premium, if any, interest and Additional Interest, if any, on the Notes when such payments are due;

(2) the Company's obligations with respect to the Notes concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payments;

(3) the rights, powers, trust, duties and immunities of the Trustee and the Company's obligations in connection therewith; and

(4) the Legal Defeasance provisions of the Indenture.

In addition, the Company may, at its option and at any time, elect to have the obligations of the Company released with respect to certain covenants that are described in the Indenture ("Covenant Defeasance") and thereafter any omission to comply with such obligations shall not constitute a Default or Event of Default with respect to the Notes. In the event Covenant Defeasance occurs, certain events (not including non-payment, bankruptcy, receivership, reorganization and insolvency events) described under "Events of Default" will no longer constitute an Event of Default with respect to the Notes.

In order to exercise either Legal Defeasance or Covenant Defeasance:

(1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders cash in U.S. dollars, non-callable U.S. government obligations, or a combination thereof, in such amounts and at such times as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, interest and Additional Interest, if any, on the Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be;

(2) in the case of Legal Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that:

(a) the Company has received from, or there has been published by, the Internal Revenue Service a ruling; or

(b) since the date of the Indenture, there has been a change in the applicable federal income tax law,

in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3) in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit pursuant to clause (1) of this paragraph (except such Default or Event of Default resulting from the failure to comply with "—Certain Covenants—Limitations on Incurrence of Additional Indebtedness" as a result of the borrowing of funds required to effect such deposit) or insofar as Defaults or Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91^st day after the date of such deposit;

(5) such Legal Defeasance or Covenant Defeasance shall not result in a breach of, or constitute a default under the Indenture or any other material agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

(6) the Company shall have delivered to the Trustee an Officers' Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders over any other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Company or others;

(7) the Company shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance have been complied with; and

(8) the Company shall have delivered to the Trustee an Opinion of Counsel (subject to customary qualifications and exclusions) to the effect that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940.

Satisfaction and Discharge

The Indenture (and all Liens on Collateral in connection with the issuance of the Notes) will be discharged and will cease to be of further effect (except as to surviving rights or registration of transfer or exchange of the Notes, as expressly provided for in the Indenture) as to all outstanding Notes when:

(1) either:

(a) all the Notes theretofore authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust) have been delivered to the Trustee for cancellation; or

(b) all Notes not theretofore delivered to the Trustee for cancellation (i) have become due and payable, (ii) will become due and payable at their stated maturity within one year or (iii) are to be called for redemption within one year under arrangements reasonably satisfactory to the Trustee, and the Company has irrevocably deposited or caused to be deposited with the Trustee funds in an amount sufficient to pay and discharge the entire Indebtedness on the Notes not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, interest and Additional Interest, if any, on the Notes to the date of deposit together with irrevocable instructions from the Company directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be;

(2) the Company has paid all other sums payable under the Indenture and the Collateral Agreements by the Company; and

(3) the Company has delivered to the Trustee an Officers' Certificate and an Opinion of Counsel stating that all conditions precedent under the Indenture relating to the satisfaction and discharge of the Indenture have been complied with.

Modification of the Indenture

From time to time, the Company, the Guarantors, the Trustee and, if such amendment, modification or supplement relates to any Collateral Agreement, the Collateral Agent, without the consent of the Holders, may amend, modify or supplement the Indenture, the Notes, the Guarantees and the Collateral Agreements:

(1) to cure any ambiguity, defect or inconsistency contained therein;

(2) to provide for uncertificated Notes in addition to or in place of certificated Notes;

(3) to provide for the assumption of the Company's or a Guarantor's obligations to Holders in accordance with the covenant described under "—Certain Covenants—Merger, Consolidation and Sale of Assets;"

(4) to make any change that would provide any additional rights or benefits to the Holders or that does not adversely affect the legal rights of any such Holder under the Indenture, the Notes, the Guarantees or the Collateral Agreements;

(5) to comply with requirements of the SEC in order to effect or maintain the qualification of the Indenture under the TIA;

(6) to allow any Subsidiary or any other Person to guarantee the Notes;

(7) to release a Guarantor as permitted by the Indenture and the relevant Guarantee; or

(8) if necessary, in connection with any addition or release of Collateral permitted under the terms of the Indenture or Collateral Agreements.

Other amendments of, modifications to and supplements to the Indenture, the Notes, the Guarantees, the Registration Rights Agreement and the Collateral Agreements may be made with the consent of the Holders of a majority in principal amount of the then outstanding Notes issued under the Indenture, except that, without the consent of each Holder affected thereby, no amendment may:

(1) reduce the amount of Notes the Holders of which must consent to an amendment, supplement or waiver of any provision of the Indenture or the Notes;

(2) reduce the rate of or change or have the effect of changing the time for payment of interest, including defaulted interest, or Additional Interest on any Notes;

(4) make any Notes payable in money other than that stated in the Notes;

(5) make any change in provisions of the Indenture protecting the right of each Holder to receive payment of principal of, premium, if any, interest and Additional Interest, if any, on such Note on or after the due date thereof or to bring suit to enforce such payment, or permitting Holders of a majority in principal amount of Notes to waive Defaults or Events of Default;

(6) amend, change or modify in any material respect the obligation of the Company to make and consummate a Change of Control Offer after the occurrence of a Change of Control or modify any of the provisions or definitions with respect thereto;

(8) release any Guarantor from any of its obligations under its Guarantee or the Indenture otherwise than in accordance with the terms of the Indenture; or

(9) release all or substantially all of the Collateral otherwise than in accordance with the terms of the Indenture and the Collateral Agreements.

Governing Law

The Indenture will provide that it, the Notes and the Guarantees will be governed by, and construed in accordance with, the laws of the State of New York but without giving effect to applicable principles of conflicts of law to the extent that the application of the law, of another jurisdiction would be required thereby.

The Trustee

The Indenture will provide that, except during the continuance of an Event of Default, the Trustee will perform only such duties as are specifically set forth in the Indenture. During the existence of an Event of Default, the Trustee will exercise such rights and powers vested in it by the Indenture, and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of such person's own affairs.

The Indenture and the provisions of the TIA contain certain limitations on the rights of the Trustee, should it become a creditor of the Company, to obtain payments of claims in certain cases or to realize on certain property received in respect of any such claim as security or otherwise. Subject to the TIA, the Trustee will be permitted to engage in other transactions;provided that if the Trustee acquires any conflicting interest as described in the TIA, it must eliminate such conflict or resign.

UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

The following is a summary of the material U.S. federal income tax consequences relating to the exchange of old notes for registered notes in the exchange offer. This discussion is a general summary only and does not address all tax aspects relating to the exchange. This discussion deals only with the U.S. federal income tax consequences to persons who hold such notes as capital assets and does not deal with the consequences to special classes of holders of the notes, such as dealers in securities or currencies, brokers, traders that mark-to-market their securities, insurance companies, tax-exempt entities, financial institutions or "financial services entities," persons with a functional currency other than the U.S. dollar, regulated investment companies, real estate investment trusts, retirement plans, expatriates or former long-term residents of the United States, persons who hold their notes as part of a straddle, hedge, "conversion transaction," "constructive sale" or other integrated investment, persons subject to the alternative minimum tax, partnerships or other pass-through entities or investors in partnerships or other pass-through entities that hold the notes. The discussion is based upon the Internal Revenue Code of 1986, as amended, which we refer to as the Code, and the Treasury Regulations promulgated thereunder, and rulings and judicial interpretations thereof, all as in effect on the date of this prospectus, any of which may be repealed or subject to change, possibly with retroactive effect.

Consequences of Tendering Old Notes

The exchange of old notes for registered notes (with substantially identical terms) in the exchange offer will not be a taxable event for U.S. federal income tax purposes, and a holder will have the same adjusted tax basis and holding period in such registered notes that the holder had in the old notes immediately before the exchange. The U.S. federal income tax consequences of holding and disposing of such registered notes will be the same as those applicable to the old notes.

THE PRECEDING DISCUSSION OF THE MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE EXCHANGE OF OLD NOTES FOR REGISTERED NOTES IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE. ACCORDINGLY, EACH INVESTOR SHOULD CONSULT ITS OWN TAX ADVISOR AS TO PARTICULAR TAX CONSEQUENCES TO IT RELATING TO THE EXCHANGE, INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS, AND OF ANY PROPOSED CHANGES IN APPLICABLE LAW.

114

PLAN OF DISTRIBUTION

Any broker-dealer who holds old notes that were acquired for its own account as a result of market-making activities or other trading activities (other than old notes acquired directly from the issuer), may exchange such old notes pursuant to the exchange offer; however, such broker-dealer may be deemed to be an "underwriter" within the meaning of the Securities Act and must, therefore, deliver a prospectus meeting the requirements of the Securities Act in connection with any resales of the registered notes received by such broker-dealer in the exchange offer, which prospectus delivery requirement may be satisfied by the delivery of such broker-dealer of this prospectus. We have agreed that, for a period ending on the earlier of (a) 180 days after the registration statement containing this prospectus is declared effective and (b) the date on which a broker-dealer is no longer required to deliver a prospectus in connection with market-making or other trading activities, we will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale. In addition, until , 2005, all dealers effecting transactions in the registered notes may be required to deliver a prospectus.

We will not receive any proceeds from any sale of registered notes by broker-dealers. Registered notes received by broker-dealers for their own account pursuant to the exchange offer may be sold from time to time in one or more transactions in the over the counter market, in negotiated transactions, through the writing of options on the registered notes or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer or the purchasers of any such registered notes. Any broker-dealer that resells registered notes that were received by it for its own account pursuant to the exchange offer and any broker or dealer that participates in a distribution of such registered notes may be deemed to be an "underwriter" within the meaning of the Securities Act and any profit on any such resale of registered notes and any commission or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. The letter of transmittal states that, by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act.

We will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests such documents in the letter of transmittal. We have agreed to pay all expenses incident to the exchange offer (including the expenses of one counsel for the holders of the notes) other than commissions or concessions of any brokers or dealers and will indemnify the holders of the notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act.

Report of Independent Registered Public Accounting Firm

To the Board of Directors
Altra Industrial Motion, Inc.

We have audited the accompanying consolidated balance sheet of Altra Industrial Motion, Inc. ("the Company"), as of December 31, 2004, and the consolidated balance sheet of its Predecessor as of December 31, 2003, and the related consolidated statements of operations and comprehensive income (loss), changes in stockholder's equity, and cash flows for the period from inception (December 1, 2004) through December 31, 2004, and of the Predecessor for the period from January 1, 2004 through November 30, 2004, and for each of the two years in the period ended December 31, 2003. These financial statements 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 Industrial Motion, Inc. at December 31, 2004, and of its Predecessor at December 31, 2003, and the consolidated results of the operations and cash flows of the Company for the period from inception (December 1, 2004) through December 31, 2004, and of its Predecessor for the period from January 1, 2004 through November 30, 2004, and for each of the two years in the period ended December 31, 2003, in conformity with U.S. generally accepted accounting principles.

As discussed in Note 6, in 2002, the Predecessor changed its method of accounting for goodwill.

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.

The financial information included herein may not reflect the consolidated financial position, operating results, and cash flows of the Company in the future or what they would have been had the Company or Predecessor been a separate, independent entity during the periods presented. Certain administrative and corporate expenditures related to the Predecessor have not been allocated to these financial statements by Colfax, as described in Note 12.

With the exception of the Boston Gear division of the Predecessor ("Boston Gear"), all subsidiaries acquired from Colfax represent separate legal entities. Boston Gear maintained its own books and records, but historically related goodwill, retirement plans, income taxes, and a portion of the worker's compensation liability were not allocated to Boston Gear. For purposes of these statements, certain assets and liabilities of Boston Gear that are included in the Predecessor financial statements represent allocations of amounts that were previously recorded on Colfax' financial statements.

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.

Discontinued Operations—Predecessor

In connection with the Predecessor's adoption of SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets," a component of the Predecessor, Bay City Forge ("Bay City"), which

F-7

was sold in December of 2002, was classified as a discontinued operation. Bay City was sold because the Predecessor determined that it was no longer a part of its core operations. Accordingly, the financial results of Bay City, for the year ended December 31, 2002, were reported as a discontinued operation and included revenues of $3.0 million, a $0.1 million pre-tax loss from discontinued operations and a $0.6 million loss, net of income taxes, from the sale of the Bay City operation.

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.

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 fair value of long-term debt is estimated to approximate the carrying amount based on current interest rates for similar types of borrowings. The estimated fair values may not represent actual values of the financial instruments that could be realized as of the balance sheet date or that will be realized in the future.

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 invested capital or stockholder's equity. Currency translation gains (losses) are included in the results of operations in the period incurred and were not material in any of the periods presented.

Reclassification

Certain prior period amounts have been reclassified in the consolidated financial statements to conform to the current period's presentation.

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.

F-8

Trade Receivables

An allowance for doubtful accounts is recorded equal to 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.

Inventories

Inventories at December 31, 2004 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.

The Predecessor's inventories are stated at the lower of cost or market using the FIFO method.

Property, Plant and Equipment

For the Company, property, plant, and equipment are stated at cost, which includes the estimated fair values of property, plant and equipment acquired on the date of the acquisition and, at December 31, 2004, net of accumulated depreciation incurred since November 30, 2004. For the Predecessor, property, plant, and equipment are stated at historic cost, net of accumulated depreciation.

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

For the Company, 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

F-9

acquisition and, at December 31, 2004, net of accumulated amortization incurred since November 30, 2004.

Goodwill

For the Company, 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.

For the Predecessor, goodwill represented costs in excess of the fair value of net assets purchased associated with the acquisitions of various companies.

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 is 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 has 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.

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.

F-10

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 $6.7 million and $0.0 million at December 31, 2004 and 2003, respectively. Related amortization expense, included as a component of interest expense, was $0.1 million, $0.0 million, $0.6 and $0.0 million for the periods from December 1, 2004 through December 31, 2004 and January 1, 2004 through November 30, 2004 and the years ended December 31, 2003 and 2002, respectively.

Revenue Recognition

Product revenues are recognized 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.

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 and amounted to $0.3 million, $3.0 million, $2.7 million and $3.1 million in the periods from December 1, 2004 through December 31, 2004 and January 1, 2004 through November 30, 2004 and the years ended December 31, 2003 and 2002, respectively.

F-11

Advertising

Advertising costs are charged to selling, general, and administrative expenses as incurred and amounted to approximately $0.2 million, $2.0 million, in 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 each of the years ended December 31, 2003 and 2002.

Stock-Based Compensation

Subsequent to year-end, the Company's Board of Directors established the 2004 Equity Incentive Plan that provides for various forms of stock based compensation to officers and senior-level employees of the Company. Awards granted under the 2004 Equity Incentive Plan are for equity instruments of Altra Holdings, Inc., the Company's parent company. The Company will account for the compensation expense of this plan under the fair value method prescribed by Statement of Financial Accounting Standard (SFAS) No. 123R, "Share-Based Payment," as appropriate, based upon the nature of the awards made.

Income Taxes

The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement basis and the tax basis of the Company's assets and liabilities using enacted statutory tax rates applicable to future years when the temporary differences are expected to reverse. The Company records a valuation allowance when it determines that it is more likely than not that all or a portion of a deferred tax asset will not be realized. The effect on deferred income tax assets and liabilities, of a change in tax rates, is recognized in income in the period that includes the enactment date.

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 December 2003, Congress passed the Medicare Prescription Drug Improvement and Modernization Act of 2003 (the Act). The Act established a prescription drug benefit under Medicare,

F-12

known as Medicare Part D, and a federal subsidy to sponsors of retiree health care benefit plans that are at least actuarially equivalent to Medicare Part D. The Financial Accounting Standards Board (the "FASB") has issued Staff Position No. 106-2, "Accounting and Disclosure Requirements Related to the Medicare Prescription Drug Improvement and Modernization Acts of 2003," which requires that the effects of the federal subsidy be considered an actuarial gain and recognized in the same manner as other actuarial gains and losses. The Predecessor recognized reductions in pension expense of $0.3 million, in the period from January 1, 2004 through November 30, 2004, as a result of the Act.

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 May 2003, the FASB issued SFAS No. 150, "Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity". SFAS No. 150 clarifies the accounting for certain financial instruments with characteristics of both liabilities and equity and requires that those instruments be classified as liabilities in statements of financial position. Previously, many of those financial instruments were classified as equity. SFAS No. 150 is effective for financial instruments entered into or modified after May 31, 2003, and otherwise is effective at the beginning of the first interim period beginning after June 15, 2003. The Company and the Predecessor have no such financial instruments and, as such, the adoption of this standard did not have any effect on the financial statements included herein.

In April 2003, the FASB issued SFAS No. 149, "Amendments of Statement 133 on Derivative Instruments and Hedging Activities". SFAS No. 149 amends and clarifies accounting for derivative instruments embedded in other contracts, and for hedging activities under SFAS No. 133. SFAS No. 149 is effective for contracts entered into or modified after June 30, 2003, and for hedging relationships designated after June 30, 2003. The Company and the Predecessor have no such derivative instruments and, as such, the adoption of this standard did not have any effect on the financial statements included herein.

Effective January 1, 2003, the Predecessor adopted SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities". This Statement requires companies to recognize costs associated with exit or disposal activities when they are incurred rather than at the date of a commitment to an exit or disposal plan. Examples of costs covered by the standard include lease termination costs and certain employee severance costs that are associated with a restructuring, discontinued operation, plant closing, or other exit or disposal activity. SFAS No. 146 was to be applied prospectively to exit or disposal activities initiated after December 31, 2002. The adoption of this standard did not have a material impact on the Predecessor's consolidated financial statements.

In January 2003, the FASB issued FIN No. 46, "Consolidation of Variable Interest Entities", expanding the guidance in Accounting Research Bulletin No. 51, "Consolidated Financial Statements",

F-13

relating to transactions involving variable interest entities. In December 2003, the FASB issued FIN No. 46 (Revised) to address certain FIN No. 46 implementation issues. The Company and its Predecessor do not have any variable interest entities and, as such, the adoption of this standard did not have any impact on the financial statements included herein.

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 common stock plus the assumption of Kilian debt in the amount of approximately $12.2 million. The purchase price of both acquisitions will be adjusted following the completion of certain negotiations surrounding adjustments to the respective seller's recorded working capital at the acquisition date. In connection with the acquisition of the Predecessor, $5.0 million of the purchase price was paid to an escrow agent for the benefit of any claims that the Company may have against the seller relating to the Purchase Agreement. Additional discussion surrounding the common stock issued for the Kilian acquisition is included in Note 12.

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 preliminary purchase price allocations. The preliminary value of the acquired assets, assumed liabilities and identified intangibles from the acquisition of the Predecessor, 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 the Predecessor have not yet been allocated across the business units acquired from the Predecessor. The Company is currently evaluating the intangibles associated with the acquisition of Kilian but has not yet completed this process. Further, and as discussed above, the final purchase price of each of the acquisitions are subject to certain purchase price adjustments which have not been finalized. The final purchase price allocations will be completed within one year of the acquisitions and are not expected to

F-14

have a material impact on the Company's financial position or results of operations. The preliminary purchase price allocations are as follows (in thousands):

		Predecessor		Kilian		Total
Total purchase price, including closing costs of approximately $3.5 million		$	183,522	$	8,864	$	192,386

Cash and cash equivalents			1,183		1,184		2,367

	Total liabilities assumed		74,648		15,303		89,951

	Net assets acquired		144,671		6,179		150,850

Excess purchase price over the fair value of net assets acquired		$	38,851	$	2,685	$	41,536

The excess of the purchase price over the fair value of the net assets acquired was recorded as goodwill.

The amounts recorded as intangible assets consist of the following:

		Predecessor		Kilian		Total
Customer relationships		$	27,802	$	—	$	27,802
Product technology and patents			5,122		—		5,122

	Total intangible assets subject to amortization		32,924		—		32,924
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 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.

F-15

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.

The estimated amortization expense for intangible assets is approximately $3.0 million in each of the next five years.

Predecessor Impairment

Effective January 1, 2002, the Predecessor adopted SFAS No. 142,Goodwill and Other Intangible Assets. This statement established a new accounting standard for goodwill and certain other indefinite-lived intangible assets and established a new method of testing those assets for impairment at the reporting-unit level using a fair-value-based approach. A reporting unit is defined as an operating segment or one level below an operating segment.

At December 30, 2001 (prior to adoption), the Predecessor had net goodwill of $95.0 million. The goodwill was evaluated for impairment by reporting unit, using historical and projected EBITDA, multiplied by industry enterprise valuation multiples, to estimate their fair value. This resulted in an impairment loss of $83.4 million, which was attributable to Nuttall Gear, Industrial Clutch, Boston

F-17

Gear, the Heavy Duty Clutch business, the Electronic Clutch Brake business, and the International Distribution business. This impairment loss is included as a cumulative effect of change in accounting principle in the Predecessor's 2002 financial statements.

7. Warranty Costs

Changes in the carrying amount of accrued product warranty costs are as follows:


	December 1, 2004 through December 31, 2004			Predecessor 11 Months ended November 30, 2004			Predecessor Year-ended December 31, 2003
Balance at beginning of period	$	1,524		$	1,300		$	1,800
Accrued warranty costs		94			1,093			1,078
Payments and adjustments		(90	)		(869	)		(1,578	)

Balance at end of period	$	1,528		$	1,524		$	1,300

8. Income Taxes

The components of the provision (benefit) for income taxes were as follows:


					Predecessor (Note 1)
		December 1, 2004 through December 31, 2004			11 Months ended November 30, 2004	Year-ended December 31, 2003			Year-ended December 31, 2002

Provision (benefit) for income taxes			(248	)	5,430	$	(1,592	)	$	2,455

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

F-18

purposes. Significant components of the deferred tax assets and liabilities as of December 31, 2004 and 2003 were as follows:

		2004					Predecessor (Note 1) 2003

Net deferred tax assets		4,180			4,923		$	7,518		$	3,083	��

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. Prior to December 1, 2004, this assessment was made in conjunction with the annual assessment for the Predecessor. A portion of the valuation allowance of Colfax was allocated to the Predecessor based upon the relative profitability of the Predecessor to Colfax in total and this allowance was allocated among related asset categories including comprehensive income.

The Company's current portion of net operating loss carryforwards primarily relates to U.S. based entities, and expires in 2024. The long-term portion of net operating loss carryfowards relates to the Company's operations in France, and has an indefinite carryforward period.

8. Income Taxes (continued)

U.S. income taxes at the statutory tax rate reconciled to the overall U.S. and foreign provision (benefit) for income taxes were as follows:

As of December 31, 2004, the Company has not recorded U.S. federal deferred income taxes on undistributed earnings from its foreign subsidiaries. It is expected that these earnings will be permanently reinvested in operations outside the U.S. It is not practical to compute the estimated deferred tax liability on these earnings. During the period from December 1, 2004 through December 31, 2004, income tax benefits were reduced by valuation allowances recorded for foreign tax credits of approximately $0.2 million and U.S. net operating loss benefits of approximately $0.3 million. During the period from January 1, 2004 through November 30, 2004, income tax benefits were reduced by valuation allowances for foreign tax credits of approximately $0.9 million.

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 is in the process of evaluating the potential impact of this legislation.

9. Pension and Other Employee Benefits

Defined Benefit (Pension) and Postretirement Benefit Plans

The Company sponsors various defined benefit (pension) and postretirement (medical and life insurance coverage) plans for certain, primarily unionized, active employees (those in the employment of the Company 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, the Company assumed the pension and postretirement benefit obligations of all active U.S. employees and all non-U.S. employees of the Predecessor. Additionally, the Company 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

F-20

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.

F-21

9. Pension and Other Employee Benefits (continued)

The following tables represent the reconciliation of the benefit obligation, fair value of plan assets and funded status of the respective defined benefit (pension) and postretirement benefit plans as of December 31, 2004 and 2003:


		Pension Benefits									Postretirement Benefits

F-22

For all pension plans presented above, the accumulated and projected benefit obligations exceed the fair value of plan assets. The accumulated benefit obligation at December 31, 2004 and 2003 was $24.7 million and $149.3 million, respectively. Non-US pension liabilities recognized in the amounts presented above are $3.2 million and $2.7 million at December 31, 2004 and 2003, respectively.

The key economic assumptions used in the computation of the respective benefit obligations for the years ended December 31, 2004 and 2003 presented above are as follows:


	Pension Benefits				Postretirement Benefits
	2004		Predecessor (Note 1) 2003		2004		Predecessor (Note 1) 2003
Weighted-average discount rate	5.8	%	6.2	%	5.8	%	6.3	%
Weighted-average rate of compensation increase	N/A		N/A		N/A		N/A

The following table represents the components of the net periodic benefit cost associated with the respective plans:


	Pension Benefits												Postretirement Benefits
				Predecessor (Note 1)											Predecessor (Note 1)

F-23

The key economic assumptions used in the computation of the respective net periodic benefit cost for the periods presented above are as follows:


	Pension Benefits								Postretirement Benefits
			Predecessor (Note 1)								Predecessor (Note 1)
	From Inception (December 1, 2004) through December 31, 2004		11 Months ended November 30, 2004		Year-ended December 31, 2003		Year-ended December 31, 2002		From Inception (December 1, 2004) through December 31, 2004		11 Months ended November 30, 2004		Year-ended December 31, 2003		Year-ended December 31, 2002
Discount rate	6.0	%	6.2	%	7.2	%	7.5	%	6.0	%	6.3	%	6.8	%	7.5	%
Expected return on plan assets	8.5	%	8.5	%	9.0	%	9.0	%	N/A		N/A		N/A		N/A
Compensation rate increase	N/A		N/A		N/A		4.0	%	N/A		N/A		N/A		N/A

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, done by a third party.

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. The assumed health care trends are a significant component of the postretirement benefit costs. A one-percentage-point change in assumed health care cost trend rates would have the following effects:

		1-Percentage- Point Increase			1-Percentage- Point Decrease
Effect on service and interest cost components for the period December 1, 2004 through December 31, 2004		$	13		$	(11	)
Effect on the December 31, 2004 post-retirement benefit obligation			2,317			(1,864	)

F-24

The asset allocations for the Company's and the Predecessor's funded retirement plans at December 31, 2004 and 2003, respectively, and the target allocation for 2005, by asset category, are as follows:

	Allocation Percentage of Plan Assets at Year-End
Asset Category	2005 Target		2004 Actual		Predecessor (Note 1) 2003 Actual
Equity securities	65	%		(i)	70	%
Fixed income securities	35	%		(i)	30	%

(i): The assets for the Company's funded retirement plan at the end of 2004 were held by the Predecessor, awaiting transfer. Once received, they will be 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 the Company periodically, but at least quarterly, to rebalance within the target guidelines. The Company 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 expected to be contributed to the plans by the Company and the expected benefit payments, which are made from the plans' assets and includes the participants' share of the costs, which is funded by participant contributions. The amounts in the table are actuarially determined and reflect the Company's best estimate given its current knowledge; actual amounts could be materially different.

		Pension Benefits		Postretirement Benefits
Expected Company contribution to plan trusts	2005	$	525	$	114
Expected benefit payments (from plan assets)	2005		181		114

F-25

Defined Contribution Plans

At November 30, 2004, the Company 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 the Company's plan and all of their account balances in the Predecessor plans were transferred to the Company's plan at Inception.

Under the terms of both the Company and Predecessor plans, eligible employees may contribute from one to fifteen percent of their compensation to the plan on a pre-tax basis. The Company 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). The Company's expense associated with the defined contribution plan was $0.3 million during the period December 1, 2004 through December 31, 2004. The Predecessor's expense was $2.4 million during the eleven months ending November 30, 2004, and $2.0 million in each of the years ending December 31, 2003 and 2002.

10. Long-Term Debt

Revolving Credit Agreement

At November 30, 2004, the Company 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 the Company to maintain certain levels of collateralized assets, as defined in the Revolving Credit Agreement. The Company 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 the Company. The Company 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 the Company'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%. The Company 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 $10,000 per quarter in service fees. The Company incurred approximately $1.9 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 the Company's assets have been pledged as collateral against outstanding borrowings under the Revolving Credit Agreement. The Revolving Credit Agreement requires the Company 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 the Company. The Company 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, 2004 however; the lender had issued $1.9 million of outstanding letters of credit on behalf of the Company.

F-26

9% Senior Secured Notes

At November 30, 2004, the Company 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 $4.9 million of deferred financing costs (included in other assets).

The Senior Notes mature on December 1, 2011 unless previously redeemed by the Company. Through December 1, 2007, the Company 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, the Company 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, the Company 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, the Company 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. Should the Company fail to file the required registration statement or there are delays in the effectiveness of such filing, the Company will incur additional interest at an annual rate of .25%, increasing by an additional .25% for each 90 day delay in the registration up to a 1% maximum amount of additional interest.

The Senior Notes are guaranteed by the Company'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 the Company's assets. The Senior Notes contain numerous terms, covenants and conditions, which impose substantial limitations on the Company. The Company was in compliance with all of the requirements of the Senior Notes and Revolving Credit Agreement at 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 percent which approximated the rates incurred by the parent company for their third-party debt. In addition to the outstanding debt payable to its parent company, the Predecessor also had $0.7 million of outstanding letters of credit at December 31, 2003.

Capital Leases (see also Note 15)

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

F-27

obligations amounted to approximately $1.1 million and $1.9 million at December 31, 2004 and 2003, respectively.

11. Stockholder's Equity

The Company has authorized, issued and outstanding 1,000 shares of $0.001 par-value common stock, all of which is held by Altra Holdings, Inc. ("Holdings"), the Company's parent and sole shareholder.

For the Predecessor, all historical equity balances are reflected in the consolidated 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.

12. Related-Party Transactions

Kilian Acquisition

As discussed in Note 3, the Company acquired Kilian in exchange for the assumption of $12.2 million of Kilian's debt and the issuance of $8.8 million of common stock issued to Holdings. Holdings had previously acquired Kilian through the exchange of preferred and common stock in Holdings that was issued to certain preferred and common shareholders of Kilian, the majority of whom were represented by Genstar Capital, L.P. ("Genstar"), one of the primary shareholders in Holdings.

Management Agreement

At November 30, 2004, the Company and Holdings entered into an advisory services agreement with 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. 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.

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 end by May 2005 and the transition of management oversight of various on-going business initiatives through May 2005. These services are to

F-28

be provided at Colfax' cost which are not expected to aggregate to a material amount or exceed in any material respects the historical cost of obtaining such services.

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 years ended December 31, 2003 and 2002. There were no accounts receivables from Danaher as of December 31, 2003. Purchases of products from Danaher amounted to $5.8 million, $7.2 million and $5.4 million in eleven months ending November 30, 2004 and the years ending December 31, 2003 and 2002, respectively. The Company had outstanding accounts payable due to Danaher of $0.8 million at December 31, 2003.

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. 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). 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 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.

13. 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 9.0%, 10.3%, 10.8%, and 11.9% of the Company's and Predecessor's sales for the periods December 1, 2004 through December 31, 2004 and January 1, 2004 through November 30, 2004 and the years ended December 31, 2003 and 2002, respectively. Outstanding accounts receivables from that customer were $2.7 million and $2.5 million at December 31, 2004 and 2003, respectively.

F-29

The Company and its Predecessor operate in a single business segment. Net sales to third parties and property, plant and equipment by geographic region are as follows (in thousands):

		Net Sales
				Predecessor (Note 1)						Property, Plant and Equipment
		December 1, 2004 through December 31, 2004		11 Months ended November 30, 2004		Year-ended December 31, 2003		Year-ended December 31, 2002		December 31, 2004		Predecessor (Note 1) December 31, 2003

	Total	$	28,726	$	275,239	$	266,765	$	253,217	$	68,919	$	62,311

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.

Approximately 32.3% of the Company's labor force (19.8% and 90.5% in the United States and Europe, respectively) is represented by collective bargaining agreements.

14. 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 years ended

F-30

December 31, 2003 and 2002 amounted to approximately $0.9 million, $11.1 million and $27.8 million, respectively, and were comprised of the following major categories:

	11 Months ended November 30, 2004		Year-ended December 31, 2003		Year-ended December 31, 2002
Accrued restructuring charge	$	—	$	—	$	7,133
Impairment or loss on sale of fixed assets		306		2,011		18,109
Period cost transition expenses		641		9,074		2,583

	$	947	$	11,085	$	27,825

Predecessor restructuring charges of approximately $7.1 million were primarily comprised of $6.7 million in severance cost related to work force reductions of approximately 315 manufacturing and administrative associates. The programs involved plant closures and outsourcing, which resulted in a loss on sale of assets of approximately $2.0 million in 2003 and a non-cash asset impairment charge of approximately $18.1 million for 2002. Certain period costs such as relocation, training, recruiting, duplicative associates and moving costs resulting from restructuring programs amounted to $0.6 million, $9.1 million and $2.6 million for the period January 1, 2004 through November 30, 2004 and the years ended December 31, 2003 and 2002, 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

F-31

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 administrative functions were centralized in Angers. This program, other than the payment of accrued severance amounts, was substantially completed in the fourth quarter of 2003.

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

F-35

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.

16. Guarantor Subsidiaries

The following tables present separately the financial position, results of operations, and cash flows for the Company and its Predecessor for: (a) the subsidiaries of the Company and its Predecessor that are guarantors of the Notes, which include all wholly-owned U.S. domestic subsidiaries of the Company (Guarantor Subsidiaries), and (b) the subsidiaries of the Company and its Predecessor that are not guaranteeing the Notes, which include all non-domestic subsidiaries of the Company (Non-Guarantor Subsidiaries). Separate financial statements of the Guarantor Subsidiaries are not presented because their guarantees are full and unconditional and joint and several, and the Company believes separate financial statements and other disclosures regarding the Guarantor Subsidiaries are not material to investors. The Notes were entered into and issued in connection with the acquisition of the Predecessor and Kilian (see Note 3.)

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these combined financial statements based on our audits.

We conducted our audits 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 examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements.

We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the combined financial statements referred to above present fairly, in all material respects, the combined financial position of Kilian Manufacturing Corporation and Kilian Canada ULC as of October 22, 2004 and December 27, 2003, and the combined results of their operations and their cash flows for the period from December 28, 2003 through October 22, 2004, February 15, 2003 through December 27, 2003, and December 29, 2002 through February 14, 2003 in conformity with accounting principles generally accepted in the United States of America.

NOTES TO COMBINED FINANCIAL STATEMENTS
KILIAN MANUFACTURING CORPORATION AND KILIAN CANADA ULC
October 22, 2004, December 27, 2003 and February 14, 2003

NOTE A—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Business and Principles of Combination: Kilian Manufacturing Corporation ("Kilian Syracuse"), along with its affiliated organization, Kilian Canada ULC formerly known as Kilian Manufacturing, Ltd. ("Kilian Canada"), headquartered in Syracuse, New York, designs and manufactures machined-race bearings and multi-component assemblies. Kilian Syracuse and Kilian Canada (collectively, the Company) manufactures its proprietarily-designed bearings and assemblies in its three manufacturing plants, one in Syracuse, New York and two in Toronto, Canada.

Kilian Syracuse was a wholly owned subsidiary of The Torrington Company (Torrington). Torrington was a subsidiary of Ingersoll-Rand Company Limited (Ingersoll-Rand) prior to being acquired by The Timken Company in February 2003. Kilian Canada was a division of Ingersoll-Rand Canada until such acquisition. On October 23, 2004 the Company was sold to The Kilian Company and 3091780 Nova Scotia Company. (also see Note B for further discussion.)

The combined financial statements include the accounts of Kilian Syracuse and Kilian Canada. All significant intercompany accounts and transactions have been eliminated in combination.

Accounting Period: The Company generally follows a "52-53" accounting calendar with its year end being the last Saturday in December.

Due to changes in ownership (see Note B) the statements of income, stockholders' equity and cash flows presented in the accompanying financial statements are for periods less than an annual accounting period and are not necessarily indicative of the results that may be expected for the full fiscal year.

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 amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Concentration of Credit and Vendor Risk: The Company generally sells its products on open account and performs periodic credit evaluations on its customers, and generally does not require collateral. The Company considers trade accounts receivable to be past due when in excess of 30 days past terms, and charges off uncollectible balances when all collection efforts have been exhausted. For customers deemed at risk, the Company will demand prepayment or payment upon shipment. Five customers comprised approximately 34% and 28% of accounts receivable at October 22, 2004 and December 27, 2003, respectively. The same five customers also comprised approximately 23%, 21% and 19% of the Company's net sales for the periods ended October 22, 2004, December 27, 2003 and February 14, 2003, respectively. The Company has not incurred significant credit losses, which is consistent with management expectations.

Raw material purchases from two suppliers comprised approximately 64%, 60% and 62% of total purchases for the periods ended October 22, 2004, December 27, 2003 and February 14, 2003, respectively. Management strongly believes that it can find alternate suppliers if necessary.

Revenue Recognition: The Company ships and bills directly to end-user customers for the majority of its sales. The Company recognizes revenue from the sales of its products upon shipment of the product, which is when title and all risk of ownership are transferred.

F-52

Accounts Receivable: Accounts receivable are recorded when invoices are issued and are presented in the balance sheet net of the allowance for doubtful accounts. Accounts receivable are written off when they are determined to be uncollectible. The allowance for doubtful accounts is estimated based on the Company's historical losses, the existing economic conditions in its industry, and the financial stability of its customers.

Inventories: Inventories are carried at the lower of cost or market, cost being determined principally on the basis of standards which approximate actual costs on the first-in first-out method (FIFO), and market being determined by net realizable value.

Property, Plant and Equipment: Property, plant, and equipment, including major renewal or betterments, are recorded at cost. Upon retirement or disposal of an asset, the cost and related accumulated depreciation are eliminated from the respective accounts and resulting gains or losses are included in operations. Expenditures for maintenance and repairs are charged to operations as incurred.

Depreciation and amortization are provided on the straight-line method over the estimated useful lives of the assets as follows:

Buildings and improvements		10 to 40 years
Machinery and equipment		3 to 12 years

Goodwill: The Company recorded as goodwill the excess of purchase price over the fair value of the identifiable net assets acquired. Statements of Financial Accounting Standards No. 142, prescribes a two step process for impairment testing of goodwill which is performed annually, as well as when an event triggering impairment may have occurred. The first step tests for impairment while the second step, if necessary, measures the impairment (also see Note E).

Income Taxes: The Company provides for income taxes in accordance with the liability method as set forth in Statements of Financial Accounting Standards No. 109,Accounting for Income Taxes. Under the liability method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and tax basis of assets and liabilities using enacted tax rates in effect with the years in which the differences are expected to reverse.

Shipping and Handling Costs: Shipping and handling costs are expensed as incurred and are included in costs of products sold.

Research and Development Costs: Research and development costs are expensed as incurred. Research and development costs amounted to approximately $83,000, $86,000, and $14,000 for the periods ended October 22, 2004, December 27, 2003 and February 14, 2003, respectively.

Foreign Currency Translation: In accordance with Financial Accounting Standards Board Statement No. 52, all balance sheet accounts of Kilian Canada are translated at current exchange rates and income statement items are translated at an average exchange rate for the year. The gain or loss resulting from translating Kilian Canada financial statements is recorded as a separate component of the combined statement of stockholder's equity as other comprehensive income (loss). Transaction gains and losses are recorded in operations.

NOTE B—CHANGES IN OWNERSHIP

On February 15, 2003, The Timken Company purchased the Torrington Company and the net assets of what is currently Kilian Canada ULC from Ingersoll-Rand Company, Ltd. in a transaction accounted for under the purchase method. Since the transaction included the Company, the purchase price has been reflected in the Company's asset bases and assumed liabilities as of that date as follows:

Purchase price	$	20,749,518
Assets acquired		(19,153,966	)
Liabilities assumed		3,235,535

Excess	$	4,831,087

On October 23, 2004 the Company was sold to the Kilian Company and 3091780 Nova Scotia Company.

NOTE C—INVENTORIES

Inventories consist of the following:

	October 22, 2004		December 27, 2003
Raw material and work in process	$	3,402,395	$	3,146,211
Finished goods		1,930,440		1,144,454

	$	5,332,835	$	4,290,665

NOTE D—INCOME TAXES

Pretax income (loss) was $5,099,292, $3,597,714, and $976,573 from domestic operations and $676,206, $(1,875,644), and $104,468 from foreign operations for the October 22, 2004, December 27, 2003 and February 14, 2003 periods.

F-54

Significant components of income tax expense (benefit) attributable to operations are as follows:

		Period ended October 22, 2004			Post-acquisition February 15 through December 27, 2003			Pre-acquisition December 29, 2002 through February 14, 2003
Current:
	Federal	$	1,920,681		$	1,788,890		$	1,130,671
	Foreign		318,092			110,443			100,424
	State		239,747			222,257			27,436

Total Current			2,478,520			2,121,590			1,258,531
Deferred:
	Federal		(241,620	)		(1,132,016	)		(708,397	)
	Foreign		(39,132	)		(101,151	)		(48,694	)
	State		(58,481	)		(273,991	)		(92,766	)

Total deferred			(339,233	)		(1,507,158	)		(849,857	)

Total current and deferred		$	2,139,287		$	614,432		$	408,674

The Company's effective tax rate differs from the statutory U.S. federal income tax rate due primarily to the effects of foreign tax rate differential, state taxes and certain expenses not deductible for federal tax purposes.

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.

F-55

Significant components of the Company's deferred tax assets and liabilities consist of the following:

		October 22, 2004			December 27, 2003
Deferred tax assets:
	Post retirement benefits	$	778,284		$	723,450
	Retirement benefits		81,277			67,435
	Non-deductible reserves/accruals		189,750			160,544
	Inventories		328,173			262,178
	Insurance reserves		563,730			314,718
	Unrealized exchange (gain)/loss		143,454			56,364

Total deferred tax assets			2,084,668			1,584,689
Deferred tax liabilities:
	Tax over book depreciation		(222,910	)		(72,224	)

Total deferred tax liabilities			(222,910	)		(72,224	)

Net deferred tax assets		$	1,861,758		$	1,512,465

Classification of net deferred tax assets:
	Current	$	1,081,652		$	737,441
	Non-current		780,106			775,024

		$	1,861,758		$	1,512,465

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Management believes it is more likely than not the Company will realize the benefits of the deferred tax assets.

As discussed in Note B, the stock of Kilian Syracuse and Kilian Canada was sold on February 15, 2003. In the United States, the parties elected under Internal Revenue Code 338(h)(10) to report the stock transaction as the sale of assets. However, the domestic and foreign tax liabilities resulting from the sale remained the responsibility of the parent companies. Income taxes have been presented in conformity with the basis of presentation for financial reporting purposes that the transaction occurred at the parent company level and the income tax effect of the sale transaction has not been reflected.

F-56

NOTE E—GOODWILL

As a result of the transactions that are more fully explained in Note B the following is a summary of the activity relating to goodwill:

Balance December 29, 2002	$	-0-
February 15, 2003—Timken purchase		4,831,087
Impairment charge		(2,173,087	)

Balances at October 22, 2004 and December 27, 2003	$	2,658,000

Goodwill and the corresponding impairment charge relates to Kilian Canada ULC. The amount of the impairment loss has been determined based on a combination of market prices and discounted cash flow calculations.

NOTE H—COMMITMENTS AND CONTINGENCIES

Litigation: The Company is a defendant in certain legal actions incidental to its business. Management is vigorously defending these actions. The Company is also currently going through various levels of environmental testing at each of the three plants as part of the acquisition by The Timken Company. Because of the current state of certain proceedings and tests, no prediction can be made as to their ultimate outcome. In the opinion of management, the ultimate liability, if any, resulting from these pending actions will not have a material impact on the Company's future results of operations or financial position.

Warranty: The Company does not offer a basic limited warranty for its proprietary products. However, the Company does offer a generic 30-day return period for defective product. The Company also will provide warranties on a specific case-by-case basis at the discretion of management. For such specific cases, the Company estimates the costs that may be incurred and records a liability in the amount of such costs at the time product revenue is recognized. Factors that affect the Company's warranty liability include the internal and external costs necessary to satisfy the warranty claim.

F-58

Balance at December 29, 2002		$	365,000

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

The following is a summary of the statutes, charter and bylaw provisions or other arrangements under which the Registrants' directors and officers are insured or indemnified against liability in their capacities as such. All the directors and officers of the Registrants are covered by insurance policies maintained and held in effect by Altra Industrial Motion, Inc. against certain liabilities for actions taken in their capacities as such, including liabilities under the Securities Act.

Section 18-108 of the Delaware Limited Liability Company Act.

Section 18-108 of the Delaware Limited Liability Company Act, or the DLLC Act, provides that a limited liability company may, and shall have the power to, indemnify and hold harmless any member or manager or other person from and against any and all claims and demands whatsoever, subject to the standards and restrictions, if any, set forth in its limited liability company agreement.

Limited Liability Company Agreement Provisions on Indemnification

The Limited Liability Company Agreement of Formsprag LLC provides that that the company shall indemnify any member or officer of the company from any claim, action, liability, loss or damage in which such person may be involved and arising from or incidental to the business or activities of the company, provided such person's conduct (i) does not constitute a breach of the duty of loyalty, (ii) does not constitute willful misconduct and (iii) such person does not receive any improper personal benefit.

The above discussion of the limited liability company registrants' LLC Agreements and of the DLLC Act is not intended to be exhaustive and is qualified in its entirety by the LLC Agreements and the DLLC Act.

REGISTRANTS EXISTING AS LIMITED PARTNERSHIPS UNDER DELAWARE LAW

Section 17-108 of the Delaware Revised Uniform Limited Partnership Act.

American Enterprises MPT Holdings, L.P. and Ameridrives International, L.P. are limited partnerships organized under the laws of the State of Delaware. Section 17-108 of the Delaware Revised Uniform Limited Partnership Act ("DRULPA") empowers a Delaware limited partnership to indemnify and hold harmless any partner or other person from and against all claims and demands whatsoever, subject to such standards and restrictions, if any, as are set forth in its partnership agreement.

Limited Partnership Agreement Provisions on Indemnification.

The Limited Partnership Agreement of American Enterprises MPT Holdings, L.P. and the Limited Partnership Agreement of Ameridrives International, L.P. authorize each partnership to indemnify, defend and hold harmless its partners, their stockholders, owners, directors, officers, employees and agents from and against any loss, liability, damage, cost or expense (including reasonable attorneys' fees) arising out of or alleged to arise out of any demands, claims, suits, actions or proceedings against any of them in or as a result of or relating to their respective capacities, actions or omissions with

II-3

respect to the partnership, or otherwise concerning the business or affairs of the partnership including, without limitation, any demands, claims, suits, actions or proceedings, initiated by any of the partnership's partners; provided, however that the acts or omissions of the partnership's general partner shall not be indemnified to the extent a court of competent jurisdiction finds, upon entry of a final judgment, that the same resulted from gross negligence, willful misconduct, recklessness, malfeasance or fraud. Indemnification will be made solely and entirely from assets of the partnership (excluding all assets of the partnership's partners other than those of and attributable to such partner's interest in the partnership), and no such partner shall be personally liable therefore. All such rights to indemnification will survive the dissolution of the partnership and the death, retirement, incompetency, insolvency or bankruptcy of any partner.

The above discussion of the limited partnership registrants' Limited Partnership Agreements and of the DRULPA is not intended to be exhaustive and is qualified in its entirety by the Limited Partnership Agreements and the DRULPA.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the registrants as disclosed above, the registrants have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

ITEM 22. 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 the provisions described under Item 20 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 counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The undersigned registrants hereby undertake:

(1) To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

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

(A) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933.

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

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

(3) That, for the purpose of determining liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

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

(5) To respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this Form, within one business day of the receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.
