PROSPECTUS SUMMARY

        You should read this summary together with the more detailed information and our financial statements and related notes appearing elsewhere or incorporated by reference in this prospectus. Unless otherwise indicated, "we," "us" and "our" refer to Aftermarket Technology Corp. and our subsidiaries.

Our Business

        We are a leading remanufacturer and distributor of drivetrain products used in the repair of automobiles and light trucks in the automotive aftermarket. Our Logistics business is a provider of value added warehouse and distribution services as well as returned material reclamation and disposition services. For 2001, we had net sales of $393.4 million, an increase of 5.6% over 2000, and income from continuing operations of $29.5 million compared to $2.4 million in 2000.

        Our Drivetrain Remanufacturing business sells factory-approved remanufactured drivetrain products directly to automobile manufacturers, or OEMs. Our Drivetrain business products consist principally of remanufactured transmissions and also include remanufactured torque converters, valve bodies and engines. The OEMs primarily use the remanufactured products as replacement parts for their domestic dealers during the warranty and post-warranty periods following the sale of a vehicle. Our principal customers for remanufactured transmissions are DaimlerChrysler Corporation, Ford Motor Company, General Motors Corporation and a number of foreign OEMs.

        Our Logistics business consists of three operating units: Logistics Services, a provider of value added warehouse and distribution services, turnkey order fulfillment and information services for AT&T Wireless Services; Material Recovery, a provider of returned material reclamation and disposition services and management of failed components (commonly referred to as cores), primarily to Ford and, to a lesser extent, General Motors; and Autocraft Electronics, an automotive electronic remanufacturing and distribution business.

RISK FACTORS

        You should carefully consider the risks described below before making an investment decision. We believe these are all the material risks currently facing our business, but additional risks we are not presently aware of or that we currently believe are immaterial may also impair our business operations. Our financial condition or results of operations could be materially adversely affected by these risks. The trading price of our common stock could decline due to any of these risks, and you may lose all or part of your investment. In assessing these risks, you should also refer to the other information included or incorporated by reference in this prospectus or any applicable prospectus supplement, including our financial statements and related notes.

We rely on a few major customers for a significant majority of our business and the loss of any of those customers, or significant changes in prices or other terms with any of our major customers, could reduce our net income and operating results.

        A few customers account for a significant majority of our net revenues each year. In 2001, we had three customers that individually accounted for more than 10% of our revenues. Ford accounted for approximately 29.6%, 30.0% and 34.6% of our net sales for 1999, 2000 and 2001, respectively, DaimlerChrysler accounted for 31.6%, 29.6% and 24.7% of our net sales in 1999, 2000 and 2001, respectively, and AT&T Wireless accounted for 6.3%, 14.1% and 17.6% of our net sales during 1999, 2000 and 2001, respectively.

        DaimlerChrysler and Ford, like other North American OEMs, generally require that their dealers using remanufactured products for warranty application use only products from approved suppliers. Although we are currently the only factory-approved supplier of remanufactured transmissions for Chrysler automobiles and light trucks and one of two suppliers to Ford, DaimlerChrysler and Ford are not obligated to continue to purchase our products and generally may terminate our agreements on 90 days notice or less. They may approve other suppliers in the future or begin remanufacturing products themselves and we may not be able to maintain or increase our sales to them. Within the last five years the standard new vehicle warranty provided by our customers has varied and shorter warranty periods could be implemented in the future. Any shortening of warranty periods could reduce the amount of warranty work performed by dealers and reduce the demand for our services.

        Substantially all of our contracts or arrangements with our customers, including the contracts with Ford and DaimlerChrysler, are terminable on 90 days notice or less. All of our major customers regularly review the pricing and terms of our contracts in light of general market changes, specific business proposals from our competitors and opportunities for our customers to insource the services and products we provide to them. Based on these periodic reviews, our major customers seek to renegotiate our agreements with them from time to time. For instance, in 2001, we reduced our prices to Chrysler, as requested by Chrysler, by approximately 5%. In addition, our arrangements with AT&T Wireless will expire at or near the end of 2002 and we expect that price reductions and other changes in terms may result.

        We expect that similar renegotiations will occur throughout the duration of our relationships with our major customers. The extent of the price decreases may depend in part on the viability and pricing of the competitive opportunities that become available to our customers from time to time. In addition, an attractive competitive opportunity for our customer that we can not meet could result in the loss of all or a significant portion of the business from that customer. Because of the short termination periods and periodic price negotiations, we cannot give any assurances of the stability of the prices for our products and, therefore, our revenue streams. Significant price fluctuations, or the loss of any material amount of business from these customers, could result in a significant decrease in our net sales and operating results.

5



Our financial results are affected by transmission failure rates which are outside our control.

        Our quarterly and annual operating results are affected by transmission failure rates, and a drop in rates could adversely affect sales or profitability or lead to variability of our operating results. Generally, if transmissions last longer, there will be less demand for our remanufactured transmissions. Transmission failure rates could drop due to a number of factors outside our control, including:

Our financial results are affected by our customers' policies which are outside our control.

        Our financial results are also affected by the policies of our OEM customers. Changes to our key OEM customers' policies that could materially affect our business include:

Our Logistics business is dependent on the strength of our customers.

        AT&T Wireless, our principal Logistics customer, operates in a highly competitive technology market. The number of cell phones sold by AT&T Wireless, whether to new subscribers or as replacement phones to existing subscribers, is dependent on its ability to keep pace with technological advancements and to provide service programs and prices that are attractive to current and potential customers. Our Logistics revenue from AT&T Wireless is substantially related to the number of phones sold by AT&T Wireless. Consequently, any material decrease in phones sold by AT&T Wireless will materially and adversely affect our Logistics revenue.

Interruptions or delays in obtaining transmission cores and component parts could impair our business.

        In our remanufacturing operations, we obtain used transmissions, engines and related components, commonly known as cores, which are sorted and either placed into immediate production or stored until needed. The majority of the cores we remanufacture are obtained from OEMs. Our ability to obtain cores of the types and in the quantities we require is critical to our ability to meet demand and expand production. With the increased acceptance in the aftermarket of remanufactured assemblies, the demand for cores has increased. We have periodically experienced situations in which the inability to obtain sufficient cores has limited our ability to accept orders. We may experience core shortages in the future. In addition, from time to time, we experience shortages of components manufactured by our OEM customers that we require for our transmission remanufacturing process. If we experience such shortages for an extended period of time, it could have a material adverse effect on our business and negatively impact our competitive position.

6



We may incur material liabilities under various federal, state, local and foreign environmental laws.

        We are subject to various evolving federal, state, local and foreign environmental laws and regulations governing, among other things, emissions to air, discharge to waters and the generation, handling, storage, transportation, treatment and disposal of a variety of hazardous and non-hazardous substances and wastes. These laws and regulations provide for substantial fines and criminal sanctions for violations and impose liability for the costs of cleaning up, and the damages resulting from, past spills, disposals or other releases of hazardous substances. In connection with our acquisition activity, we have conducted certain investigations of facilities we have acquired and their compliance with applicable environmental laws. Similarly, in the course of lease terminations, we have generally conducted investigations into potential environmental impacts resulting from our operations. These investigations revealed various environmental matters and conditions that could expose us to liability or which have required us to undertake compliance-related improvements or remedial activities. Furthermore, one of our former subsidiaries, RPM, leased several facilities in Azusa, California located within what is now a federal Superfund site. The entity that leased the facilities to RPM has been identified by the United States Environmental Protection Agency as one of the many potentially responsible parties for environmental liabilities associated with that Superfund site. Any liability we may have from this site or otherwise under environmental laws could materially affect our business.

Substantial competition could reduce our market share and significantly harm our financial performance.

        While we believe that our business is well positioned to compete in our two primary market segments, transmission remanufacturing and logistics, our industry segments are highly competitive. We may not be successful in competing against other companies, some of which are larger than us and have greater financial and other resources available to them than we do. Increased competition could require us to reduce prices or take other actions which may have an adverse effect on our operating results.

Our stock price is volatile, and you may not be able to recover your investment if our stock price declines.

        The stock price of our common stock has been volatile and can be expected to be affected by factors such as:

        In addition to the factors listed above affecting us, our competitors and the economy generally, the stock price of our common stock may be affected by any significant sale of shares by our principal stockholders. As of May 31, 2002, Aurora Equity Partners L.P. and Aurora Overseas Equity Partners I, L.P. collectively owned 9,761,478 shares of our common stock, 2,318,452 shares of which have been registered for re-sale pursuant to this prospectus. Any significant sales by the Aurora partnerships could have a negative impact on our stock price.

7



Our future operating results may fluctuate significantly.

        We may experience significant variations in our future quarterly results of operations. These fluctuations may result from many factors, including the condition of our industry in general and shifts in demand and pricing for our products. Our operating results are also highly dependent on our level of gross profit as a percentage of net sales. Our gross profits percentage fluctuates due to numerous factors, some of which may be outside of our control. These factors include:

        Results of operations in any period, therefore, should not be considered indicative of the results to be expected for any future period.

Our success depends on our ability to retain our senior management and to attract and retain key personnel.

        Our success depends to a significant extent on the efforts and abilities of our senior management team. We have various programs in place to motivate, reward and retain our management team, including bonus and stock option plans. However, the loss of one or more of these persons could have an adverse effect on our business. Our success and plans for future growth will also depend on our ability to hire, train and retain skilled workers in all areas of our business. We currently do not have key executive insurance relating to our senior management team.

We cannot predict the impact of unionization efforts or labor shortages on our business.

        From time to time, labor unions have indicated their interest in organizing our workforce. Given that our OEM customers are in the highly unionized automotive industry, our business is likely to continue to attract the attention of union organizers. While these efforts have not been successful to date, we cannot give any assurance that we will not experience additional union activity in the future. Any union organization activity, if successful, could result in increased labor costs and, even if unsuccessful, could result in a temporary disruption of our production capabilities and a distraction to our management.

        Additionally, we need qualified managers and a number of skilled employees with technical experience in order to operate our business successfully. From time to time, there may be a shortage of skilled labor which may make it more difficult and expensive for us to attract and retain qualified employees. If we are unable to attract and retain qualified individuals or our costs to do so increase significantly, our operations would be materially adversely affected.

We are subject to risks associated with future acquisitions.

        An important element of our growth strategy is the acquisition and integration of complementary businesses in order to broaden product offerings, capture market share and improve profitability. We will not be able to acquire other businesses if we cannot identify suitable acquisition opportunities, obtain financing on acceptable terms or reach mutually agreeable terms with acquisition candidates. The negotiation of potential acquisitions as well as the integration of an acquired business could require us to incur significant costs and cause diversion of our management's time and resources. Future acquisitions by us could result in:

8


        Some or all of these items could have a material adverse effect on our business. The businesses we acquire in the future may not achieve sales and profitability that justify our investment. In addition, to the extent that consolidation becomes more prevalent in our industry, the prices for suitable acquisition candidates may increase to unacceptable levels and limit our growth.

We may encounter problems in integrating the operations of companies that we acquire.

        We may encounter difficulties in integrating any businesses we acquire with our operations. The success of these transactions depends on our ability to:

        Furthermore, we may not realize the benefits we anticipated when we entered into these transactions. In addition, after we have completed an acquisition, our management must be able to assume significantly greater responsibilities, and this in turn may cause them to divert their attention from our existing operations. Any of the foregoing could have a material adverse effect on our business and results of operations.

Our level of indebtedness and the terms of our indebtedness could adversely affect our business and liquidity position.

        As of April 30, 2002, our outstanding indebtedness was $181.5 million and we had cash on hand of $27.5 million. We expect that our indebtedness, including borrowings under our credit facility, may increase from time to time in the future for various reasons, including fluctuations in operating results, capital expenditures and possible acquisitions. Our consolidated indebtedness level could materially affect our business because:

        In addition, our credit facility requires us to meet specified financial ratios and limits our ability to enter into various transactions. If we default on any of our indebtedness, or if we are unable to obtain necessary liquidity, our business could be adversely affected.

Our controlling stockholders have the ability to influence all matters requiring the approval of our board of directors and our stockholders.

        We are controlled by the Aurora partnerships. As of May 31, 2002, the Aurora partnerships held approximately 56% of our voting power, through direct ownership of shares and voting arrangements.

9



If all shares covered by this prospectus are sold, the Aurora partnerships will hold approximately 40% of our voting power and as a result will continue to be able to exercise substantial control over us. As a result, it may be more difficult for a third party to acquire us. See "Selling Stockholders" on page 12 and the information under Item 13. "Certain Relationships and Related Transactions" in our Annual Report on Form 10-K for the year ended December 31, 2001 incorporated by reference herein. If the Aurora partnerships sell at least 1,153,944 shares, their collective beneficial ownership of our common stock will drop below 50% and the base annual management fee we pay to them will be reduced from $550,000 to $440,000.

Our certificate of incorporation contains provisions that may hinder or prevent a change in control of our company.

        Provisions of our certificate of incorporation could make it more difficult for a third party to obtain control of us, even if such a change in control would benefit our stockholders. Our board of directors can issue preferred stock without stockholder approval. Your rights could be adversely affected by the rights of holders of preferred stock that we issue in the future. All of these provisions could discourage a third party from obtaining control of us. Such provisions may also impede a transaction in which our stockholders could receive a premium over then current market prices and our stockholders' ability to approve transactions that they consider in their best interests.

DESCRIPTION OF CAPITAL STOCK

        The following description of our capital stock and provisions of our certificate of incorporation and bylaws is intended as a summary only and is qualified in its entirety by reference to the provisions of our certificate of incorporation and bylaws, which are incorporated herein by reference, and to Delaware law.

General

        Our authorized capital stock consists of 30,000,000 shares of common stock, of which 23,745,111 shares were issued and outstanding as of May 31, 2002, and 2,000,000 shares of preferred stock, none of which are issued and outstanding.

Common Stock

        Each holder of common stock is entitled to one vote for each share held of record on each matter submitted to a vote of stockholders. Holders of common stock do not have the right to cumulate their votes in the election of directors. Subject to preferences that may be granted to the holders of preferred stock, each holder of common stock is entitled to share ratably in distributions to stockholders and to receive ratably dividends that are declared by the board of directors out of legally available funds. In the event of our liquidation or dissolution, each holder of common stock is entitled to share ratably in all of our assets remaining after payment of liabilities. Holders of common stock have no conversion, preemptive or other subscription rights, and there are no redemption rights or sinking fund provisions with respect to our common stock. Our outstanding common stock is validly issued, fully paid and non-assessable. We may issue additional shares of common stock from time to time.

Preferred Stock

        Our board of directors, without further action by the holders of common stock, may issue shares of preferred stock and may fix or alter the voting rights, redemption provisions (including sinking fund provisions), dividend rights, dividend rates, liquidation preferences, conversion rights and the designation of and number of shares constituting any wholly unissued series of preferred stock.

Warrants

        There are currently outstanding warrants to purchase 70,176 shares of our common stock. These warrants are held by Dr. Michael Hartnett, one of our directors, and are exercisable at any time until December 2004 at a price of $1.67 per share.

Anti-Takeover Statute

        Section 203 of the Delaware General Corporation Law generally prohibits a Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the transaction is approved by the board of directors prior to the transaction, the interested stockholder owned at least 85% of the outstanding voting stock when it became an interested stockholder or the business combination is approved by the board and by the affirmative vote of at least 662/3% of the outstanding voting stock which is not owned by the interested stockholder. A "business combination" includes mergers, specified asset sales and other transactions resulting in a financial benefit to the stockholder. An "interested stockholder" is a person who, together with affiliates and associates, owns (or within three years, did own) 15% or more of the corporation's voting stock.

15


Limitation of Liability and Indemnification of Directors and Officers

        Our certificate of incorporation limits the liability of directors to the maximum extent permitted by Delaware law. Delaware law provides that directors of a company will not be personally liable for monetary damages for breach of their fiduciary duties as directors, except for liability for any breach of their duty of loyalty to the company or its stockholders, acts or omissions not in good faith or involving intentional misconduct or a knowing violation of law, unlawful payment of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the Delaware General Corporation Law or any transaction from which the director derived an improper personal benefit.

        Our bylaws provide that we will pay all costs and expenses (including legal expenses) incurred by and indemnify from any monetary liability our present and former officers and directors, unless a determination is made that the person did not act in good faith and in a manner he reasonably believed to be in or not opposed to our best interests, or, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. There is no action or proceeding pending or, to our knowledge, threatened which may result in a claim for indemnification by any of our directors or officers.

        We believe that the provisions of our certificate of incorporation and bylaws are necessary to attract and retain qualified persons as officers and directors.

Transfer Agent and Registrar

        The transfer agent and registrar for our common stock is American Stock Transfer.

16



PLAN OF DISTRIBUTION

        We are registering the shares of our common stock at the request of the selling stockholders. We have agreed to pay the expenses associated with the preparation and filing of the registration statement of which this prospectus is a part. We may suspend the use of this prospectus and any supplements in certain circumstances due to pending corporate developments.

        The selling stockholders may offer the shares of our common stock from time to time after the date of this prospectus and will determine the time, manner and size of each sale. They may sell the shares at market prices prevailing at the time of sale, at prices related to such prevailing prices, at negotiated prices or at fixed prices.

        The methods by which the selling stockholders may sell the shares of our common stock include:

        The selling stockholders may use agents to sell the shares. If this happens, the agents may receive discounts or commissions. If required, a supplement to this prospectus will set forth the applicable commission or discount, if any, and the names of any underwriters, brokers, dealers or agents involved in the sale of the shares. The selling stockholders and any underwriters, brokers, dealers or agents that participate in the distribution of our common stock offered hereby may be deemed to be "underwriters" within the meaning of the Securities Act of 1933, and any profit on the sale of shares by them and any discounts, commissions, concessions and other compensation received by them may be deemed to be underwriting discounts and commissions under the Securities Act.

        At the time a particular offering of shares is made hereunder, to the extent required by Rule 424 under the Securities Act of 1933, we will file a prospectus supplement setting forth:

        We and the selling stockholders also may agree to indemnify underwriters, selling brokers, dealer managers or similar securities professionals that participate in transactions involving shares of our common stock against certain liabilities arising under the Securities Act of 1933.

Item 15. Indemnification of Officers and Directors

        The indemnification provisions applicable to our directors and officers are set forth in Article IX of the Certificate of Incorporation and Article VII of the Bylaws, respectively, as follows:

ARTICLE IX
LIABILITY AND INDEMNIFICATION

        To the fullest extent permitted by the Delaware General Corporation Law, as the same exists or may hereafter be amended (the "Delaware Law"), a director of the Corporation shall not be liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director. The Corporation shall indemnify, in the manner and to the fullest extent permitted by the Delaware Law, any person (or the estate of any person) who is or was a party to, or is threatened to be made a party to, any threatened, pending or completed action, suit or proceeding, whether or not by or in the right of the Corporation, and whether civil, criminal, administrative, investigative or otherwise, by reason of the fact that such person is or was a director or officer of the Corporation, or is or was serving at the request of the Corporation as a director or officer of another corporation, partnership, joint venture, trust or other enterprise. The Corporation may indemnify, in the manner and to the fullest extent permitted by the Delaware Law, any person (or the estate of any person) who is or was a party to, or is threatened to be made a party to, any threatened, pending or completed action, suit or proceeding, whether or not by or in the right of the Corporation, and whether civil, criminal, administrative, investigative or otherwise, by reason of the fact that such person is or was an employee or agent of the Corporation, or is or was serving at the request of the Corporation as an employee or agent of another corporation, partnership, joint venture, trust or other enterprise. Expenses incurred by any such director, officer, employee or agent in defending any such action, suit or proceeding may be advanced by the Corporation prior to the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director, officer, employee or agent to repay such amount if it shall ultimately be determined that he or she is not entitled to be indemnified as authorized by the Delaware Law and this Article X. The Corporation may, to the fullest extent permitted by the Delaware Law, purchase and maintain insurance on behalf of any such director,

II-1



officer, employee or agent against any liability which may be asserted against such person. To the fullest extent permitted by the Delaware Law, the indemnification provided herein shall include expenses (including attorneys' fees), judgments, fines and amounts paid in settlement and, in the manner provided by the Delaware Law, any such expenses may be paid by the Corporation in advance of the final disposition of such action, suit or proceeding. The indemnification provided herein shall not be deemed to limit the right of the Corporation to indemnify any other person for any such expenses to the fullest extent permitted by the Delaware Law, nor shall it be deemed exclusive of any other rights to which any person seeking indemnification from the Corporation may be entitled under any agreement, vote of stockholders or disinterested directors, or otherwise, both as to action in such person's official capacity and as to action in another capacity while holding such office.

        No repeal or modification of the foregoing paragraph shall adversely affect any right or protection of a director of the Corporation existing by virtue of the foregoing paragraph at the time of such repeal or modification.

SECTION 7.01 ACTION, ETC., OTHER THAN BY OR IN THE RIGHT OF THE CORPORATION. The Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the Corporation) by reason of the fact that he is or was a director, officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Corporation, and with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, that he had reasonable cause to believe that his conduct was unlawful.

SECTION 7.02 ACTIONS, ETC., BY OR IN THE RIGHT OF THE CORPORATION. The Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that he is or was a director, officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys' fees) actually and reasonably incurred by him in connection with the defense or settlement of such action or suit if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Corporation, except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable for negligence or misconduct in the performance of his duty to the Corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

SECTION 7.03 DETERMINATION OF RIGHT OF INDEMNIFICATION. Any indemnification under Section 7.01 or 7.02 (unless ordered by a court) shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification of the director, officer, employee or agent

II-2



is proper in the circumstances because he has met the applicable standard of conduct set forth in Section 7.01 and 7.02. Such determination shall be made (i) by the Board by a majority vote of a quorum consisting of directors who were not parties to such action, suit or proceeding, or (ii) if such a quorum is not obtainable, or, even if obtainable a quorum of disinterested directors so directs, by independent legal counsel in a written opinion, or (iii) by the stockholders.

SECTION 7.04 INDEMNIFICATION AGAINST EXPENSES OF SUCCESSFUL PARTY. Notwithstanding the other provisions of this Article, to the extent that a director, officer, employee or agent of the Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in Section 7.01 or 7.02, or in defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by him in connection therewith.

SECTION 7.05 PREPAID EXPENSES. Expenses incurred by an officer or director in defending a civil or criminal action, suit or proceeding may be paid by the Corporation in advance of the final disposition of such action, suit or proceeding as authorized by the Board in the specific case upon receipt of an undertaking by or on behalf of the director or officer to repay such amount unless it shall ultimately be determined that he is entitled to be indemnified by the Corporation as authorized in this Article. Such expenses incurred by other employees and agents may be so paid upon such terms and conditions, if any, as the Board deems appropriate.

SECTION 7.06 OTHER RIGHTS AND REMEDIES. The indemnification provided by this Article shall not be deemed exclusive of any other rights to which those seeking indemnification may be entitled under any Bylaws, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person.

SECTION 7.07 INSURANCE. Upon resolution passed by the Board, the Corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not the Corporation would have the power to indemnify him against such liability under the provisions of this Article.

SECTION 7.08 CONSTITUENT CORPORATIONS. For the purposes of this Article, references to "the Corporation" include all constituent corporations absorbed in a consolidation or merger as well as the resulting or surviving corporation, so that any person who is or was a director, officer, employee or agent of such a constituent corporation or is or was serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise shall stand in the same position under the provisions of this Article with respect to the resulting or surviving corporation as he would if he had served the resulting or surviving corporation in the same capacity.

SECTION 7.09 OTHER ENTERPRISES, FINES AND SERVING AT CORPORATION'S REQUEST. For purposes of this Article, references to "other enterprises" shall include employee benefit plans; references to "fines" shall include any excise taxes assessed on a person with respect to any employee benefit plan; and references to "serving at the request of the Corporation" shall include any service as a director, officer, employee or agent of the Corporation which imposes duties on, or involves services by, such director, officer, employee, or agent with respect to an employee benefit plan, its participants, or beneficiaries; and a person who acted in good faith and in a manner he reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner "not opposed to the best interests of the Corporation" as referred to in this Article.

II-3



Insurance

        We have obtained a directors' and officers' liability insurance policy insuring our directors and officers against certain losses resulting from wrongful acts committed by them as our directors and officers, including liabilities arising under the Securities Act.

Indemnification Agreements

        We have entered into separate but identical indemnification agreements with each of our directors and executive officers. These agreements provide for, among other things, indemnification to the fullest extent permitted by law and advancement of expenses. In addition, Aurora Equity Partners L.P. and Aurora Overseas Equity Partners I, L.P. indemnify the directors of the Company who are affiliated with Aurora Capital Group.

Item 17. Undertakings.

        The undersigned registrant hereby undertakes:

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

II-4


provided, however, that the undertakings set forth in paragraphs (i) and (ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference into this Registration Statement.

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

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

        (4)    That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

        (5)    Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 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 of 1933 and will be governed by the final adjudication of such issue.

        The undersigned registrant hereby undertakes that:

        (1)    For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upn Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

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