ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Section 145 of the General Corporation Law of the State of Delaware (the "Delaware Law") authorizes the Registrant to indemnify the officers and directors of the Company, under certain circumstances and subject to certain conditions and limitations as stated therein, against all expenses and liabilities incurred by or imposed upon them as a result of actions, suits and proceedings, civil or criminal, brought against them as such officers and directors if they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the Registrant and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was unlawful.

Reference is hereby made to Article VI of the Registrant's By-laws, a copy of which is filed as Exhibit 3.02, which provides for indemnification of officers and directors of the Registrant to the full extent authorized by
Section 145 of the Delaware Law. Section 7 of Article VI of the Bylaws authorizes the Registrant to purchase and maintain insurance on behalf of any officer, director, employee, trustee or agent of the Registrant or its subsidiaries against any liability asserted against or incurred by them in such capacity or arising out of their status as such, whether or not the Registrant would have the power to indemnify such officer, director, employee, trustee or agent against such liability under the provisions of such Article or Delaware law.

The Registrant maintains a directors' and officers' insurance policy which insures the officers and directors of the Registrant from any claim arising out of an alleged wrongful act by such persons in their respective capacities as officers and directors of the Registrant.

Section 102(b)(7) of the Delaware Law permits corporations to eliminate or limit the personal liability of a director to the corporation or its stockholders for monetary damages for breach of a fiduciary duty of care as a director. Reference is made to Article Sixth of the Registrant's Certificate of Incorporation, a copy of which is filed as Exhibit 3.01, which limits a director's liability in accordance with such Section.

Reference is made to Section 6 of the U.S. Purchase Agreement and the International Purchase Agreement, copies of which are filed as Exhibit 1.01 and 1.02, respectively, for information concerning indemnification arrangements among the Registrant and the Underwriters.

ITEM 17. UNDERTAKINGS

The undersigned Registrant hereby undertakes to provide to the Underwriters at the closing specified in the Underwriting Agreement certificates in such denominations and registered in such names as required by the Underwriters to permit prompt delivery to each purchaser.

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 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 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes that:

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

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

Ladies and Gentlemen:

American Axle & Manufacturing Holdings, Inc., a Delaware corporation (the "Company") confirms its agreement with Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch") and each of the other U.S. Underwriters named in Schedule A hereto (collectively, the "U.S. Underwriters", which term shall also include any underwriter substituted as hereinafter provided in Section 10 hereof), for whom Merrill Lynch, Credit Suisse First Boston Corporation, Donaldson, Lufkin & Jenrette Securities Corporation, Morgan Stanley & Co. Incorporated and PaineWebber Incorporated are acting as representatives (in such

1

capacity, the "U.S. Representatives"), with respect to (i) the sale by the Company and the purchase by the U.S. Underwriters, acting severally and not jointly, of the respective numbers of shares of Common Stock, par value $0.01 per share, of the Company ("Common Stock") set forth in Schedule A hereto and
(ii) the grant by the Company to the U.S. Underwriters, acting severally and not jointly, of the option described in Section 2(b) hereof to purchase all or any part of 840,000 additional shares of Common Stock to cover over-allotments, if any. The aforesaid 5,600,000 shares of Common Stock (the "Initial U.S. Securities") to be purchased by the U.S. Underwriters and all or any part of the 840,000 shares of Common Stock subject to the option described in Section 2(b) hereof (the "U.S. Option Securities") are hereinafter called, collectively, the "U.S. Securities".

It is understood that the Company is concurrently entering into an agreement dated the date hereof (the "International Purchase Agreement") providing for the offering by the Company of an aggregate of 1,400,000 shares of Common Stock (the "Initial International Securities") through arrangements with certain underwriters outside the United States and Canada (the "International Managers") for whom Merrill Lynch International, Credit Suisse First Boston Corporation, Donaldson, Lufkin & Jenrette International, Morgan Stanley & Co. International Limited and PaineWebber International (U.K.) Ltd. are acting as lead managers (the "Lead Managers") and the grant by the Company to the International Managers, acting severally and not jointly, of an option to purchase all or any part of the International Managers' pro rata portion of up to 210,000 additional shares of Common Stock solely to cover over allotments, if any (the "International Option Securities" and, together with the U.S. Option Securities, the "Option Securities"). The Initial International Securities and the International Option Securities are hereinafter called the "International Securities." It is understood that (a) the Company is not obligated to sell, and the U.S. Underwriters are not obligated to purchase, any Initial U.S. Securities unless all of the Initial International Securities are contemporaneously purchased by the International Managers, and (b) the Company is not obligated to sell, and the International Managers are not obligated to purchase, any Initial International Securities unless all of the Initial U.S. Securities are contemporaneously purchased by the U.S. Underwriters.

2

The U.S. Underwriters and the International Managers are hereinafter collectively called the "Underwriters," the Initial U.S. Securities and the Initial International Securities are hereinafter collectively called the "Initial Securities," and the U.S. Securities, and the International Securities are hereinafter collectively called the "Securities."

The Underwriters will concurrently enter into an Intersyndicate Agreement of even date herewith (the "Intersyndicate Agreement") providing for the coordination of certain transactions among the Underwriters under the direction of Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated (in such capacity, the "Global Coordinator").

The Company understands that the U.S. Underwriters propose to make a public offering of the U.S. Securities as soon as the U.S. Representatives deem advisable after this Agreement has been executed and delivered.

The Company and the Underwriters agree that up to 700,000 shares of Securities to be purchased by the Underwriters (the "Reserved Securities") shall be reserved for sale by the Underwriters to certain eligible employees and persons having business relationships with the Company, as part of the distribution of the Securities by the Underwriters, subject to the terms of this Agreement, the applicable rules, regulations and interpretations of the National Association of Securities Dealers, Inc. (the "NASD") and all other applicable laws, rules and regulations. To the extent that such Reserved Securities are not orally confirmed for purchase by such eligible employees and persons having business relationships with the Company by the first business day after the date of this Agreement, such Reserved Securities may be offered to the public as part of the public offering contemplated hereby.

The Company has filed with the Securities and Exchange Commission
(the "Commission") a registration statement on Form S-1 (No. 333-53491)
covering the registration of the Securities under the Securities Act of 1933, as amended (the "1933 Act"), including the related preliminary prospectus or prospectuses. Promptly after execution and delivery of this Agreement, the Company will either (i) prepare and file a prospectus in accordance with the provisions of Rule 430A ("Rule 430A") of the rules and regulations of the Commission under the 1933 Act (the "1933 Act Regulations") and

3

paragraph (b) of Rule 424 ("Rule 424(b)") of the 1933 Act Regulations or (ii) if the Company has elected to rely upon Rule 434 ("Rule 434") of the 1933 Act Regulations, prepare and file a term sheet (a "Term Sheet") in accordance with the provisions of Rule 434 and Rule 424(b). Two forms of prospectuses are to be used in connection with the offering and sale of the Securities: one relating to the U.S. Securities (the "Form of U.S. Prospectus") and one relating to the International Securities (the "Form of International Prospectus"). The Form of International Prospectus is identical to the Form of U.S. Prospectus, except for the front cover and back cover pages and the information under the caption "Underwriting". The information included in such prospectus or in such Term Sheet, as the case may be, that was omitted from such registration statement at the time it became effective but that is deemed to be part of such registration statement at the time it became effective (a) pursuant to paragraph (b) of Rule 430A is referred to as "Rule 430A Information" or (b) pursuant to paragraph (d) of Rule 434 is referred to as "Rule 434 Information." The Form of U.S. Prospectus and Form of International Prospectus used before such registration statement became effective, and any prospectus that omitted, as applicable, the Rule 430A Information or the Rule 434 Information, that was used after such effectiveness and prior to the execution and delivery of this Agreement, is herein called a "preliminary prospectus." Such registration statement, including the exhibits thereto and schedules thereto at the time it became effective and including the Rule 430A Information and the Rule 434 Information, as applicable, is herein called the "Registration Statement." Any registration statement filed pursuant to Rule 462(b) of the 1933 Act Regulations is herein referred to as the "Rule 462(b) Registration Statement," and after such filing the term "Registration Statement" shall include the Rule 462(b) Registration Statement. The final Form of U.S. Prospectus and the final Form of International Prospectus in the forms first furnished to the Underwriters for use in connection with the offering of the Securities are herein called the "U.S. Prospectus" and the "International Prospectus" respectively, and collectively the "Prospectuses." If Rule 434 is relied on, the terms "U.S. Prospectus" and "International Prospectus" shall refer to the preliminary U.S. Prospectus dated January 8, 1999 and preliminary International Prospectus dated January 8, 1999, respectively, each together with the applicable Term Sheet, and all references in this Agreement to the date of the Prospectuses shall mean the date of the Term Sheet. For purposes of this Agreement, all references to

4

the Registration Statement, any preliminary prospectus, the U.S. Prospectus, the International Prospectus or any Term Sheet or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system ("EDGAR").

SECTION 1. Representations and Warranties. The Company represents and warrants to each U.S. Underwriter as of the date hereof, as of the Closing Time referred to in Section 2(c) hereof, and as of each Date of Delivery (if any) referred to in Section 2(b) hereof, and agrees with each U.S. Underwriter, as follows:

(i) Compliance with Registration Requirements. Each of the Registration Statement and any Rule 462(b) Registration Statement has become effective under the 1933 Act and no stop order suspending the effectiveness of the Registration Statement or any Rule 462(b) Registration Statement has been issued under the 1933 Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company, are contemplated by the Commission, and any request on the part of the Commission for additional information has been complied with.

At the respective times the Registration Statement, any Rule
462(b) Registration Statement and any post-effective amendments thereto became effective and at the Closing Time (and, if any U.S. Option Securities are purchased, at the Date of Delivery), the Registration Statement, the Rule 462(b) Registration Statement and any amendments and supplements thereto complied and will comply in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations and did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. Neither of the Prospectuses nor any amendments or supplements thereto, at the time the Prospectuses or any amendments or supplements were issued and at the Closing Time (and, if any U.S. Option Securities are purchased, at the Date of Delivery), included or will include an untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. If Rule 434 is used, the Company will comply with the

5

requirements of Rule 434 and the Prospectuses shall not be "materially different", as such term is used in Rule 434, from the prospectuses included in the Registration Statement at the time it became effective.

9

the Company or any subsidiary pursuant to, the Agreements and Instruments (except for such conflicts, breaches or defaults or liens, charges or encumbrances that would not result in a Material Adverse Effect), nor will such action result in any violation of the provisions of the charter or by-laws of the Company or any subsidiary or any applicable law, statute, rule, regulation, judgment, order, writ or decree of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Company or any subsidiary or any of their assets, properties or operations.

Any certificate signed by any officer of the Company or any of its subsidiaries delivered to the U.S. Representatives or to counsel for the U.S. Underwriters and the International Managers shall be deemed a representation and warranty by the Company to each U.S. Underwriter and each International Manager as to the matters covered thereby.

SECTION 2. Sale and Delivery to U.S. Underwriters; Closing.

(a) Initial U.S. Securities. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company agrees to sell to each U.S. Underwriter, severally and not jointly, and each U.S. Underwriter, severally and not jointly, agrees to purchase from the Company, at the price per share set forth in Schedule B, that number of Initial U.S. Securities set forth in Schedule A opposite the name of such U.S. Underwriter, plus any additional number of Initial U.S. Securities which such U.S. Underwriter may become obligated to purchase pursuant to the provisions of Section 10 hereof, subject, in each case, to such adjustments among the U.S. Underwriters as the U.S. Representatives in their sole discretion shall make to eliminate any sales or purchases of fractional securities.

15

(b) U.S. Option Securities. In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company hereby grants an option to the U.S. Underwriters, severally and not jointly, to purchase up to an additional 840,000 shares of Common Stock, at the price per share set forth in Schedule B, less an amount per share equal to any dividends or distributions declared by the Company and payable on the Initial U.S. Securities but not payable on the U.S. Option Securities. The option hereby granted will expire 30 days after the date hereof and may be exercised in whole or in part from time to time only for the purpose of covering over-allotments which may be made in connection with the offering and distribution of the Initial U.S. Securities upon notice by the Global Coordinator to the Company setting forth the number of U.S. Option Securities as to which the several U.S. Underwriters are then exercising the option and the time and date of payment and delivery for such U.S. Option Securities. Any such time and date of delivery (a "Date of Delivery") shall be determined by the Global Coordinator, but shall not be later than seven full business days after the exercise of said option, nor in any event prior to the Closing Time, as hereinafter defined. If the option is exercised as to all or any portion of the U.S. Option Securities, each of the U.S. Underwriters, acting severally and not jointly, will purchase that proportion of the total number of U.S. Option Securities then being purchased which the number of Initial U.S. Securities set forth in Schedule A opposite the name of such U.S. Underwriter bears to the total number of Initial U.S. Securities, and the Company shall sell such number of U.S. Option Securities, subject in each case to such adjustments as the Global Coordinator in its discretion shall make to eliminate any sales or purchases of fractional shares.

(c) Payment. Payment of the purchase price for, and delivery of certificates for, the Initial U.S. Securities shall be made at the offices of Mayer Brown & Platt, 190 South LaSalle Street, Chicago, Illinois, or at such other place as shall be agreed upon by the Global Coordinator and the Company, at 9:00 A.M. (Eastern time) on the third (fourth, if the pricing occurs after 4:30 P.M. (Eastern time) on any given day) business day after the date hereof (unless postponed in accordance with the provisions of Section 10), or such other time not later than ten business days after such date as shall be agreed upon by the Global Coordinator and the Company (such time and date of payment and delivery being herein called "Closing Time").

16

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

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

(d) Denominations; Registration. Certificates for the Initial U.S. Securities and the U.S. Option Securities, if any, shall be in such denominations and registered in such names as the U.S. Representatives may request in writing at least one full business day before the Closing Time or the relevant Date of Delivery, as the case may be. The certificates for the Initial U.S. Securities and the U.S. Option Securities, if any, will be made available for examination and packaging by the U.S. Representatives in The City of New York not later than 10:00 A.M. (Eastern time) on the business day prior to the Closing Time or the relevant Date of Delivery, as the case may be.

17

the requirements of Rule 430A or Rule 434, as applicable, and will notify the Global Coordinator immediately, and confirm the notice in writing, (i) when any post-effective amendment to the Registration Statement shall become effective, or any supplement to the Prospectuses or any amended Prospectuses shall have been filed, (ii) of the receipt of any comments from the Commission, (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectuses or for additional information, and (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of any preliminary prospectus, or of the suspension of the qualification of the Securities for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes. The Company will promptly effect the filings necessary pursuant to Rule 424(b) and will take such steps as it deems necessary to ascertain promptly whether the form of prospectus transmitted for filing under Rule 424(b) was received for filing by the Commission and, in the event that it was not, it will promptly file such prospectus. The Company will make every reasonable effort to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible moment.

(b) Filing of Amendments. The Company will give the Global Coordinator notice of its intention to file or prepare any amendment to the Registration Statement (including any filing under Rule 462(b)), any Term Sheet or any amendment, supplement or revision to either the prospectus included in the Registration Statement at the time it became effective or to the Prospectuses, will furnish the Global Coordinator with copies of any such documents a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Global Coordinator or counsel for the U.S. Underwriters shall reasonably object in writing within a reasonable period of time.

(c) Delivery of Registration Statements. The Company has furnished or will deliver to the U.S. Representatives and counsel for the U.S. Underwriters, without charge, signed copies of the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein) and signed copies of all consents and

The U.S. Prospectus and any amendments or supplements thereto furnished to the U.S. Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

(e) Continued Compliance with Securities Laws. The Company will comply with the 1933 Act and the 1933 Act Regulations so as to permit the completion of the distribution of the Securities as contemplated in this Agreement, the International Purchase Agreement and in the Prospectuses. If at any time when a prospectus is required by the 1933 Act to be delivered in connection with sales of the Securities, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the U.S. Underwriters or for the Company, to amend the Registration Statement or amend or supplement the Prospectuses in order that the Prospectuses will not include any untrue statements of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement the Prospectuses in order to comply with the requirements of the 1933 Act or the 1933 Act

19

Regulations, the Company will promptly prepare and file with the Commission, subject to Section 3(b), such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectuses comply with such requirements, and the Company will furnish to the U.S. Underwriters such number of copies of such amendment or supplement as the U.S. Underwriters may reasonably request.

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

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

20

documents and notices required by the New York Stock Exchange of companies that have securities listed thereon.

During a period of 180 days from the date of the Prospectuses, the Company will not, without the prior written consent of Merrill Lynch, (i) directly or indirectly, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of any share of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or file any registration statement under the 1933 Act with respect to any of the foregoing or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Common Stock, whether any such swap or transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (A) the Securities to be sold hereunder or under the International Purchase Agreement, (B) grants of stock options and other awards pursuant to the terms of the Company's stock option plans in effect on the date hereof and described in the Prospectuses, (C) any shares of Common Stock issued by the Company upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof and referred to in the Prospectuses or (D) offers, sales and issuances of shares of Common Stock, options, rights or warrants to purchase or any securities convertible into or exercisable or exchangeable for Common Stock in connection with acquisitions of businesses, companies or assets by the Company so long as the recipients of such shares, options, rights, warrants or convertible securities are subject to the restrictions of this Section 3(j) until the expiration of such 180 day period.

The Underwriters will notify the Company as to which persons will need to be so restricted. At the request of the Underwriters, the Company will direct the transfer agent to place a stop transfer restriction upon such securities for such period of time. Should the Company release, or seek to release, from such restrictions any of the Reserved Securities, the Company agrees to reimburse the Underwriters for any reasonable expenses including, without limitation, legal expenses they incur in connection with such release.

(a) Effectiveness of Registration Statement. The Registration Statement, including any Rule 462(b) Registration Statement, has become effective and at Closing Time no stop order suspending the effectiveness of the Registration Statement shall have been issued under the 1933 Act or proceedings therefor initiated or threatened by the Commission, and any request on the part of the Commission for additional information shall have been complied with to the reasonable satisfaction of counsel to the U.S. Underwriters. A prospectus containing the Rule 430A Information shall have been filed with the Commission in accordance with Rule 424(b) (or a post-effective amendment providing such information shall have been filed and declared effective in accordance with the requirements of Rule 430A) or, if the Company has elected to rely upon Rule 434, a Term Sheet shall have been filed with the Commission in accordance with Rule 424(b).

23

(b) Opinion of Counsel for Company. At Closing Time, the U.S. Representatives shall have received the favorable opinion, dated as of Closing Time, of Simpson Thacher & Bartlett, counsel for the Company, and Patrick S. Lancaster, Esq., General Counsel of the Company, in form and substance satisfactory to counsel for the U.S. Underwriters, together with signed or reproduced copies of such letter for each of the other U.S. Underwriters to the effect set forth in Exhibits A-1 and A-2 hereto and to such further effect as counsel to the U.S. Underwriters may reasonably request.

In giving such opinion such counsel may rely, as to all matters governed by the laws of jurisdictions other than the law of the State of New York, the federal law of the United States and the General Corporation Law of the State of Delaware, upon the opinions of counsel satisfactory to the U.S. Representatives. Such counsel may also state that, insofar as such opinion involves factual matters, they have relied, to the extent they deem proper, upon certificates of officers of the Company and its subsidiaries and certificates of public officials.

(d) Officers' Certificate. At Closing Time, there shall not have been, since the date hereof or since the respective dates as of which information is given in the Prospectuses, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company or any of its subsidiaries whether or not arising in the ordinary course of business, and the U.S. Representatives shall have received a certificate of the President or a Vice President of the Company and of the chief financial or chief accounting officer of the Company, dated as of Closing Time, to the effect that (i) there

In the event that the U.S. Underwriters exercise their option provided in Section 2(b) hereof to purchase all or any portion of the U.S. Option Securities, the representations and warranties of the Company contained herein and the statements in any certificates furnished by the Company and any subsidiary of the Company shall be true and correct as of each Date of Delivery and, at the relevant Date of Delivery, the U.S. Representatives shall have received:

(i) Officers' Certificate.

(l) Additional Documents. At Closing Time and at each Date of Delivery, counsel for the U.S. Underwriters shall have been furnished with such documents and opinions as they may require for the purpose of enabling them to pass upon the issuance and sale of the Securities as herein contemplated, or in order to evidence the accuracy of any of the representations or warranties, or the fulfillment of any of the conditions, herein contained; and all proceedings taken by the Company in connection with the issuance and sale of the Securities as herein contemplated shall be satisfactory in form and substance to the U.S. Representatives and counsel for the U.S. Underwriters.

Section shall not have been fulfilled when and as required to be fulfilled, this Agreement, or, in the case of any condition to the purchase of U.S. Option Securities on a Date of Delivery which is after the Closing Time, the obligations of the several U.S. Underwriters to purchase the relevant U.S. Option Securities, may be terminated by the U.S. Representatives by notice to the Company at any time at or prior to Closing Time or such Date of Delivery, as the case may be, and such termination shall be without liability of any party to any other party except as provided in Section 4 and except that Sections 1, 6, 7 and 8 shall survive any such termination and remain in full force and effect.

SECTION 6. Indemnification.

(a) Indemnification of U.S. Underwriters. The Company agrees to indemnify and hold harmless each U.S. Underwriter and each person, if any, who controls any U.S. Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including the Rule 430A Information and the Rule 434

27

Information, if applicable, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus or the Prospectuses (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company; and

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by Merrill Lynch), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that (A) this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any U.S. Underwriter through the U.S. Representatives expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430A Information and the Rule 434 Information, if applicable, or any preliminary prospectus or the U.S. Prospectus (or any amendment or supplement thereto) and (B) as to any preliminary prospectus, this indemnity agreement shall not inure to the benefit of any U.S. Underwriter or any person, if any, who controls any U.S. Underwriter within the meaning of Section 15 of

28

the 1933 Act or Section 20 of the 1934 Act on account of any loss, liability, claim, damage or expense arising from the fact that such U.S. Underwriter sold Securities to a person to whom there was not sent or given, at or prior to the written confirmation of such sale, a copy of the U.S. Prospectus (as then amended or supplemented) in any case where such delivery is required by the 1933 Act if the Company has previously furnished copies thereof to such U.S. Underwriter in the quantities requested and the loss, liability, claim, damage or expense of such U.S. Underwriter results from an untrue statement or omission of a material fact contained in such preliminary prospectus which the Company has sustained the burden of proving was corrected in the U.S. Prospectus (as then amended or supplemented).

(b) Indemnification of Company, Directors and Officers. Each U.S. Underwriter severally agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including the Rule 430A Information and the Rule 434 Information, if applicable, or any preliminary prospectus or the U.S. Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by such U.S. Underwriter through the U.S. Representatives expressly for use in the Registration Statement (or any amendment thereto) or such preliminary prospectus or the U.S. Prospectus (or any amendment or supplement thereto).

(c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to
Section 6(a) above, counsel to the

29

indemnified parties shall be selected by Merrill Lynch; and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or
Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel which are reimbursable under this Section 6 or Section 7, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by
Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement, which notice shall include a statement by the indemnified party that it proposes to enter into such settlement on such terms to the extent permitted by this Section 6(d), at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

30

(e) Indemnification for Reserved Securities. In connection with the offer and sale of the Reserved Securities, the Company agrees to indemnify and hold harmless the Underwriters from and against any and all losses, expenses and liabilities incurred by them as a result of (i) the failure of the designated employees or other persons to pay for and accept delivery of shares which, immediately following the effectiveness of the Registration Statement, were subject to a properly confirmed agreement to purchase and (ii) the violation of any securities laws of foreign jurisdictions where Reserved Securities have been offered.

SECTION 7. Contribution. If the indemnification provided for in
Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the U.S. Underwriters on the other hand from the offering of the U.S. Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the U.S. Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company on the one hand and the U.S. Underwriters on the other hand in connection with the offering of the U.S. Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the U.S. Securities pursuant to this Agreement (before deducting expenses) received by the Company and the total underwriting discount received by the U.S. Underwriters, in each case as set forth on the cover of the U.S. Prospectus, or, if Rule 434 is used, the corresponding location on the Term Sheet, bear to the aggregate initial public offering price of the U.S. Securities as set forth on such cover.

31

The relative fault of the Company on the one hand and the U.S. Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the U.S. Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the U.S. Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the U.S. Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no U.S. Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the U.S. Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such U.S. Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

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

For purposes of this Section 7, each person, if any, who controls a U.S. Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such U.S. Underwriter, and each director of the Company, each officer of the Company who signed the Registration

32

Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The U.S. Underwriters' respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Initial U.S. Securities set forth opposite their respective names in Schedule A hereto and not joint.

SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any U.S. Underwriter or controlling person, or by or on behalf of the Company, and shall survive delivery of the Securities to the U.S. Underwriters.

SECTION 9. Termination of Agreement.

(a) Termination; General. The U.S. Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to Closing Time
(i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the U.S. Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company or any of its subsidiaries, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the U.S. Representatives, impracticable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange, or if trading generally on the New York Stock Exchange has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by the New York Stock Exchange or by order of the Commission, the NASD or any other governmental authority, or

33

(iv) if a banking moratorium has been declared by Federal or New York authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7 and 8 shall survive such termination and remain in full force and effect.

SECTION 10. Default by One or More of the U.S. Underwriters. If one or more of the U.S. Underwriters shall fail at Closing Time or a Date of Delivery to purchase the U.S. Securities which it or they are obligated to purchase under this Agreement (the "Defaulted Securities"), the U.S. Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting U.S. Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth. If, however, the U.S. Representatives shall not have completed such arrangements within such 24-hour period, then:

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

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

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

34

In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the U.S. Underwriters to purchase and the Company to sell the relevant U.S. Option Securities, as the case may be, either (i) the U.S. Representatives or (ii) the Company shall have the right to postpone the Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectuses or in any other documents or arrangements. As used herein, the term "U.S. Underwriter" includes any person substituted for a U.S. Underwriter under this Section 10.

SECTION 11. Default by the Company. If the Company shall fail at Closing Time or at the Date of Delivery to sell the number of U.S. Securities that it is obligated to sell hereunder, then this Agreement shall terminate without any liability on the part of any nondefaulting party; provided, however, that the provisions of Sections 1, 4, 6, 7 and 8 shall remain in full force and effect. No action taken pursuant to this Section shall relieve the Company from liability, if any, in respect of such default.

SECTION 12. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the U.S. Underwriters shall be directed to the U.S. Representatives at Merrill Lynch, Sears Tower Building, Suite 5500, Chicago, Illinois 60606, attention of Michael O'Grady; and notices to the Company shall be directed to it at 1840 Holbrook Avenue, Detroit, Michigan 48212, attention of Patrick S. Lancaster, Esq.

SECTION 13. Parties. This Agreement shall inure to the benefit of and be binding upon the U.S. Underwriters, the Company and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the U.S. Underwriters, the Company and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and

35

provisions hereof are intended to be for the sole and exclusive benefit of the U.S. Underwriters, the Company and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any U.S. Underwriter shall be deemed to be a successor by reason merely of such purchase.

SECTION 14. GOVERNING LAW AND TIME. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. EXCEPT AS OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

SECTION 15. Effect of Headings. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

36

If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company a counterpart hereof, whereupon this instrument, along with all counterparts, will become a binding agreement among the U.S. Underwriters and the Company in accordance with its terms.

Very truly yours,

(i) The Company is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not result in a Material Adverse Effect.

A-2-1


Statement, except for such defaults that would not result in a Material Adverse Effect.

(iv) To such counsel's knowledge, there is not pending or threatened any action, suit, proceeding, inquiry or investigation, to which the Company or any subsidiary is a party, or to which the property of the Company or any subsidiary is subject, before or brought by any court or governmental agency or body, domestic or foreign, which might reasonably be expected to result in a Material Adverse Effect, or which might reasonably be expected to materially and adversely affect the properties or assets thereof or the consummation of the transactions contemplated in the U.S. Purchase Agreement and the International Purchase Agreement or the performance by the Company of its obligations thereunder.

(v) To such counsel's knowledge, no filing, consent, approval, authorization, registration or qualification of or with any governmental agency or body or any court, is required for the issue and sale of the Shares by the Company and the compliance by the Company with all of the provisions of the U.S. Purchase Agreement and International Purchase Agreement, except for the registration under the 1933 Act of the Shares, and such consents, approvals, authorizations, registrations or qualifications as may be required under state or foreign securities or Blue Sky laws in connection with the purchase and distribution of the Shares by the Underwriters.

Annex A

FORM OF ACCOUNTANTS' COMFORT LETTER PURSUANT TO SECTION 5(e)

We are independent public accountants with respect to the Company within the meaning of the 1933 Act and the applicable published 1933 Act Regulations

(i) in our opinion, the audited financial statements and the related financial statement schedules included in the Registration Statement and the Prospectus comply as to form in all material respects with the applicable accounting requirements of the 1933 Act and the published rules and regulations thereunder;

(ii) on the basis of procedures (but not an examination in accordance with generally accepted auditing standards) consisting of a reading of the unaudited interim consolidated financial statements of the Company for the three month periods ended March 31, 1997 and March 31, 1998 included in the Registration Statement and the Prospectus (collectively, the "Quarterly Financials"), a reading of the latest available unaudited interim consolidated financial statements of the Company, a reading of the minutes of all meetings of the stockholders and directors of the Company and its subsidiaries and the ____________ and ____________ Committees of the Board of Directors of the Company and any subsidiary committees since January 1, 1998, inquiries of certain officials of the Company and its subsidiaries responsible for financial and accounting matters, a review of interim financial information in accordance with standards established by the American Institute of Certified Public Accountants in Statement on Auditing Standards No. 71, Interim Financial Information ("SAS 71"), with respect to the three-month periods ended March 31, 1997 and March 31, 1998 and such other inquiries and procedures as may be specified in such letter, nothing came to our attention that caused us to believe that:

(A) the Quarterly Financials included in the Registration Statement and the Prospectus do not comply as to form in all material respects with the applicable accounting requirements of the 1933 Act and the 1933 Act Regulations or any material modifications should be made to the unaudited consolidated financial statements included in the Registration Statement and the

A-1

Prospectus for them to be in conformity with generally accepted accounting principles;

(B) at [_________, 19___ and at] a specified date not more than five days prior to the date of this Agreement, there was any change in the ___________ of the Company and its subsidiaries or any decrease in the __________ of the Company and its subsidiaries or any increase in the __________ of the Company and its subsidiaries, in each case as compared with amounts shown in the latest balance sheet included in the Registration Statement, except in each case for changes, decreases or increases that the Registration Statement discloses have occurred or may occur; or

(C) [for the period from _________, 19___ to _________, 19___ and ] for the period from _________, 19___ to a specified date not more than five days prior to the date of this Agreement, there was any decrease in _________, __________ or ___________, in each case as compared with the comparable period in the preceding year, except in each case for any decreases that the Registration Statement discloses have occurred or may occur;

(iii) based upon the procedures set forth in clause (ii) above and a reading of the Selected Financial Data included in the Registration Statement and a reading of the financial statements from which such data were derived, nothing came to our attention that caused us to believe that the Selected Financial Data included in the Registration Statement do not comply as to form in all material respects with the disclosure requirements of Item 301 of Regulation S-K of the 1933 Act, that the amounts included in the Selected Financial Data are not in agreement with the corresponding amounts in the audited consolidated financial statements for the respective periods or that the financial statements not included in the Registration Statement from which certain of such data were derived are not in conformity with generally accepted accounting principles;

(iv) we have compared the information in the Registration Statement under selected captions with the disclosure requirements of Regulation S-K of the 1933 Act and on the basis of limited procedures specified herein nothing came to our attention that caused us to believe that this information does not comply as to form in all material

A-2

respects with the disclosure requirements of Items 302, 402 and
503(d), respectively, of Regulation S-K;

(v) based upon the procedures set forth in clause (ii) above, a reading of the unaudited financial statements of the Company for [the most recent period] that have not been included in the Registration Statement and a review of such financial statements in accordance with SAS 71, nothing came to our attention that caused us to believe that the unaudited amounts for _____________ for the [most recent period] do not agree with the amounts set forth in the unaudited consolidated financial statements for those periods or that such unaudited amounts were not determined on a basis substantially consistent with that of the corresponding amounts in the audited consolidated financial statements;

(vi) we are unable to and do not express any opinion on the Pro Forma Condensed Consolidated Financial Data (the "Pro Forma Statements) included in the Registration Statement or on the pro forma adjustments applied to the historical amounts included in the Pro Forma Statements; however, for purposes of this letter we have:

(A) read the Pro Forma Statements;

(B) performed [an audit] [a review in accordance with SAS 71] of the financial statements to which the pro forma adjustments were applied;

(C) made inquiries of certain officials of the Company who have responsibility for financial and accounting matters about the basis for their determination of the pro forma adjustments and whether the Pro Forma Statements comply as to form in all material respects with the applicable accounting requirements of Rule 11-02 of Regulation S-X; and

(D) proved the arithmetic accuracy of the application of the pro forma adjustments to the historical amounts in the Pro Forma Statements; and on the basis of such procedures and such other inquiries and procedures as specified herein, nothing came to our attention that caused us to believe that the Pro Forma Statements included in the Registration Statement do not comply as to form in all material respects with the applicable requirements of Rule 11-02 of Regulation

A-3

S-X or that the pro forma adjustments have not been properly applied to the historical amounts in the compilation of those statements; and

(vii) in addition to the procedures referred to in clause (ii) above, we have performed other procedures, not constituting an audit, with respect to certain amounts, percentages, numerical data and financial information appearing in the Registration Statement, which are specified herein, and have compared certain of such items with, and have found such items to be in agreement with, the accounting and financial records of the Company.

Ladies and Gentlemen:

American Axle & Manufacturing Holdings, Inc., a Delaware corporation (the "Company") confirms its agreement with Merrill Lynch International ("Merrill Lynch") and each of the other International Managers named in Schedule A hereto (collectively, the "International Managers", which term shall also include any underwriter substituted as hereinafter provided in Section 10 hereof), for whom Merrill Lynch, Credit Suisse First Boston Corporation, Donaldson, Lufkin & Jenrette International, Morgan Stanley & Co. International Limited and PaineWebber International (U.K.) Limited are acting as lead managers (in such capacity, the "Lead Managers"), with respect to (i) the sale by the Company and the purchase by the International Managers, acting severally and not jointly, of the respective numbers of shares of Common Stock, par value $0.01 per share, of the Company ("Common Stock") set forth in Schedule A hereto and (ii) the grant by the Company to the Lead Managers, acting severally and not jointly, of the option described in Section 2(b) hereof to purchase all or any part of 210,000 additional shares of Common Stock to cover over-allotments, if any. The aforesaid 1,400,000 shares of Common Stock (the "Initial International Securities") to be purchased by the International Managers and all or any part of the 210,000 shares of Common Stock subject to the option described in Section 2(b) hereof

1

(the "International Option Securities") are hereinafter called, collectively, the "International Securities".

It is understood that the Company is concurrently entering into an agreement dated the date hereof (the "U.S. Purchase Agreement") providing for the offering by the Company of an aggregate of 5,600,000 shares of Common Stock (the "Initial U.S. Securities") through arrangements with certain underwriters inside the United States and Canada (the "U.S. Underwriters") for whom Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Credit Suisse First Boston Corporation, Donaldson, Lufkin & Jenrette Securities Corporation, Morgan Stanley & Co. Incorporated and PaineWebber Incorporated are acting as representatives (the "Representatives") and the grant by the Company to the U.S. Underwriters, acting severally and not jointly, of an option to purchase all or any part of the U.S. Underwriters' pro rata portion of up to 840,000 additional shares of Common Stock solely to cover over allotments, if any (the "U.S. Option Securities" and, together with the International Option Securities, the "Option Securities"). The Initial U.S. Securities and the U.S. Option Securities are hereinafter called the "U.S. Securities." It is understood that (a) the Company is not obligated to sell, and the International Managers are not obligated to purchase, any Initial International Securities unless all of the Initial U.S. Securities are contemporaneously purchased by the U.S. Underwriters and (b) the Company is not obligated to sell, and the U.S. Underwriters are not obligated to purchase, any Initial U.S. Securities unless all of the Initial International Securities are contemporaneously purchased by the International Managers.

The International Mangers and the U.S. Underwriters are hereinafter collectively called the "Underwriters," the Initial International Securities and the Initial U.S. Securities are hereinafter collectively called the "Initial Securities," and the International Securities, and the U.S. Securities are hereinafter collectively called the "Securities."

The Underwriters will concurrently enter into an Intersyndicate Agreement of even date herewith (the "Intersyndicate Agreement") providing for the coordination of certain transactions among the Underwriters under the direction of Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated (in such capacity, the "Global Coordinator").

The Company understands that the International Managers propose to make a public offering of the International Securities as soon as the Lead Managers deem advisable after this Agreement has been executed and delivered.

The Company and the International Managers understand that up to 700,000 shares of the Initial U.S. Securities to be purchased by

2

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

The Company has filed with the Securities and Exchange Commission (the "Commission") a registration statement on Form S-1 (No. 333-53491) covering the registration of the Securities under the Securities Act of 1933, as amended (the "1933 Act"), including the related preliminary prospectus or prospectuses. Promptly after execution and delivery of this Agreement, the Company will either (i) prepare and file a prospectus in accordance with the provisions of Rule 430A ("Rule 430A") of the rules and regulations of the Commission under the 1933 Act (the "1933 Act Regulations") and paragraph (b) of Rule 424 ("Rule
424(b)") of the 1933 Act Regulations or (ii) if the Company has elected to rely upon Rule 434 ("Rule 434") of the 1933 Act Regulations, prepare and file a term sheet (a "Term Sheet") in accordance with the provisions of Rule 434 and Rule
424(b). Two forms of prospectuses are to be used in connection with the offering and sale of the Securities: one relating to the International Securities (the "Form of International Prospectus") and one relating to the U.S. Securities (the "Form of U.S. Prospectus"). The Form of U.S. Prospectus is identical to the Form of International Prospectus, except for the front cover and back cover pages and the information under the caption "Underwriting". The information included in such prospectus or in such Term Sheet, as the case may be, that was omitted from such registration statement at the time it became effective but that is deemed to be part of such registration statement at the time it became effective (a) pursuant to paragraph (b) of Rule 430A is referred to as "Rule 430A Information" or (b) pursuant to paragraph (d) of Rule 434 is referred to as "Rule 434 Information." The Form of International Prospectus and Form of U.S. Prospectus used before such registration statement became effective, and any prospectus that omitted, as applicable, the Rule 430A Information or the Rule 434 Information, that was used after such effectiveness and prior to the execution and delivery of this Agreement, is herein called a "preliminary prospectus." Such registration statement, including the exhibits thereto and schedules thereto at the time it became effective and including the Rule 430A Information and the Rule 434 Information, as applicable, is herein called the "Registration Statement." Any registration

3

statement filed pursuant to Rule 462(b) of the 1933 Act Regulations is herein referred to as the "Rule 462(b) Registration Statement," and after such filing the term "Registration Statement" shall include the Rule 462(b) Registration Statement. The final Form of International Prospectus and the final Form of U.S. Prospectus in the forms first furnished to the Underwriters for use in connection with the offering of the Securities are herein called the "International Prospectus" and the "U.S. Prospectus" respectively, and collectively the "Prospectuses." If Rule 434 is relied on, the terms "International Prospectus" and "U.S. Prospectus" shall refer to the preliminary International Prospectus dated January 8, 1999 and preliminary U.S. Prospectus dated January 8, 1999, respectively, each together with the applicable Term Sheet, and all references in this Agreement to the date of the Prospectuses shall mean the date of the Term Sheet. For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus, the International Prospectus, the U.S. Prospectus or any Term Sheet or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system ("EDGAR").

SECTION 1. Representations and Warranties. The Company represents and warrants to each International Manager as of the date hereof, as of the Closing Time referred to in Section 2(c) hereof, and as of each Date of Delivery (if any) referred to in Section 2(b) hereof, and agrees with each International Manager as follows:

(i) Compliance with Registration Requirements. Each of the Registration Statement and any Rule 462(b) Registration Statement has become effective under the 1933 Act and no stop order suspending the effectiveness of the Registration Statement or any Rule 462(b) Registration Statement has been issued under the 1933 Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company, are contemplated by the Commission, and any request on the part of the Commission for additional information has been complied with.

At the respective times the Registration Statement, any Rule
462(b) Registration Statement and any post-effective amendments thereto became effective and at the Closing Time (and, if any International Option Securities are purchased, at the Date of Delivery), the Registration Statement, the Rule 462(b) Registration Statement and any amendments and supplements thereto complied and will comply in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations and did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not

4

misleading. Neither of the Prospectuses nor any amendments or supplements thereto, at the time the Prospectuses or any amendments or supplements were issued and at the Closing Time (and, if any International Option Securities are purchased, at the Date of Delivery), included or will include an untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. If Rule 434 is used, the Company will comply with the requirements of Rule 434 and the Prospectuses shall not be "materially different", as such term is used in Rule 434, from the prospectuses included in the Registration Statement at the time it became effective. The representations and warranties in this subsection shall not apply to statements in or omissions from the Registration Statement or the International Prospectus made in reliance upon and in conformity with information furnished to the Company in writing by any International Manager through the Lead Managers expressly for use in the Registration Statement or the International Prospectus.

Each preliminary prospectus and the prospectuses filed as part of the Registration Statement as originally filed or as part of any amendment thereto, or filed pursuant to Rule 424 under the 1933 Act, complied when so filed in all material respects with the 1933 Act Regulations and each preliminary prospectus and each of the Prospectuses delivered to the Underwriters for use in connection with this offering was identical to the electronically transmitted copy thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

(ii) Independent Accountants. The accountants who certified the financial statements and supporting schedule included in the Registration Statement are independent public accountants as required by the 1933 Act and the 1933 Act Regulations.

(iii) Financial Statements. The financial statements included in the Registration Statement and the Prospectuses, together with the related schedule and notes, present fairly in all material respects the financial position of the Company and its consolidated subsidiaries at the dates indicated and the respective statement of income, shareholders' equity and cash flows of the Company and its consolidated subsidiaries for the periods specified; said financial statements have been prepared in conformity with generally accepted accounting principles ("GAAP") applied on a consistent basis throughout the periods involved. The supporting schedule included in the Registration Statement presents fairly in all material respects in accordance with GAAP the information required to be stated therein. The

5

selected financial data and the summary financial information included in the Prospectuses present fairly in all material respects the information shown therein and have been compiled on a basis consistent with that of the audited financial statements included in the Registration Statement. The pro forma financial statement and the related notes thereto included in the Registration Statement and the Prospectuses present fairly in all material respects the information shown therein, have been prepared and presented in accordance with the Commission's rules and guidelines with respect to pro forma financial statements and have been properly compiled on the bases described therein, and the assumptions used in the preparation thereof are reasonable and the adjustments used therein are appropriate to give effect to the transactions and circumstances referred to therein.

(iv) No Material Adverse Change in Business. Since the respective dates as of which information is given in the Registration Statement and the Prospectuses, except as otherwise stated therein, (A) there has been no material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries (taken as a whole), whether or not arising in the ordinary course of business (a "Material Adverse Effect"), (B) there have been no transactions entered into by the Company or any of its subsidiaries, other than those in the ordinary course of business, which are material with respect to the Company and its subsidiaries (taken as a whole), and
(C) there has been no dividend or distribution of any kind declared, paid or made by the Company on any class of its capital stock.

(v) Good Standing of the Company. The Company has been duly organized and is validly existing as a corporation in good standing under the laws of the State of Delaware and has corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Prospectuses and to enter into and perform its obligations under this Agreement and under the U.S. Purchase Agreement; and the Company is duly qualified as a foreign corporation to transact business and is in good standing in each other jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not result in a Material Adverse Effect.

(vi) Good Standing of Subsidiaries. Each "significant subsidiary" of the Company (as such term is defined in Rule 1-02 of Regulation S-X) (each a "Subsidiary" and, collectively, the "Subsidiaries") has been duly organized and is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation, has corporate power and

6

authority to own, lease and operate its properties and to conduct its business as described in the Prospectuses and is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not result in a Material Adverse Effect; except as otherwise disclosed in the Registration Statement, all of the issued and outstanding capital stock of each such Subsidiary has been duly authorized and validly issued, is fully paid and non-assessable and is owned by the Company, directly or through subsidiaries, free and clear of any security interest, mortgage, pledge, lien, encumbrance, claim or equity; none of the outstanding shares of capital stock of any Subsidiary was issued in violation of the preemptive or similar rights of any securityholder of such Subsidiary. The only Subsidiaries of the Company are the Subsidiaries listed on Exhibit 21 to the Registration Statement.

(vii) Capitalization. The authorized, issued and outstanding capital stock of the Company is as set forth in the Prospectuses in the column entitled "Historical" under the caption "Capitalization" (except for subsequent issuances, if any, pursuant to this Agreement or the International Purchase Agreement, pursuant to reservations, agreements or employee benefit plans referred to in the Prospectuses or pursuant to the exercise of convertible securities or options referred to in the Prospectuses). The shares of issued and outstanding capital stock have been duly authorized and validly issued and are fully paid and non-assessable; none of the outstanding shares of capital stock was issued in violation of the preemptive or other similar rights of any securityholder of the Company.

(viii) Authorization of Agreement. This Agreement and the U.S. Purchase Agreement have been duly authorized, executed and delivered by the Company.

(ix) Authorization and Description of Securities. The Securities to be purchased by the International Managers and the U.S. Underwriters from the Company have been duly authorized for issuance and sale to the International Managers pursuant to this Agreement and to the U.S. Underwriters pursuant to the U.S. Purchase Agreement and, when issued and delivered by the Company pursuant to this Agreement and the U.S. Purchase Agreement, respectively, against payment of the consideration set forth herein and therein, will be validly issued and fully paid and non-assessable; the Common Stock conforms to all statements relating thereto contained in the Prospectuses and such description conforms to the rights set forth in the instruments defining the same; no holder of the Securities will be subject to personal liability by reason of being such a holder; and the

7

issuance of the Securities is not subject to the preemptive or other similar rights of any securityholder of the Company.

(x) Absence of Defaults and Conflicts. Neither the Company nor any of its subsidiaries is in violation of its charter or by-laws or in default, or, to the Company's knowledge, alleged by any other party to be in default, in the performance or observance of any obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or other agreement or instrument to which the Company or any of its subsidiaries is a party or by which it or any of them may be bound, or to which any of the property or assets of the Company or any subsidiary is subject (collectively, "Agreements and Instruments") except for such defaults that would not result in a Material Adverse Effect; and the execution, delivery and performance of this Agreement and the U.S. Purchase Agreement and the consummation of the transactions contemplated herein and therein and the use of the proceeds from the sale of the Securities as described in the Prospectuses under the caption "Use of Proceeds" and compliance by the Company with its obligations under this Agreement and the U.S. Purchase Agreement have been duly authorized by all necessary corporate action and do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default or Repayment Event (as defined below) under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any subsidiary pursuant to, the Agreements and Instruments (except for such conflicts, breaches or defaults or liens, charges or encumbrances that would not result in a Material Adverse Effect), nor will such action result in any violation of the provisions of the charter or by-laws of the Company or any subsidiary or any applicable law, statute, rule, regulation, judgment, order, writ or decree of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Company or any subsidiary or any of their assets, properties or operations. As used herein, a "Repayment Event" means any event or condition which gives the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder's behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company or any subsidiary.

(xi) Absence of Labor Dispute. No labor dispute with the employees of the Company or any subsidiary exists or, to the knowledge of the Company, is imminent, and the Company is not aware of any existing or imminent labor disturbance by the employees of any of its or any subsidiary's principal suppliers, manufacturers, customers or contractors, which, in either case,

8

may reasonably be expected to result in a Material Adverse Effect.

(xii) Absence of Proceedings. There is no action, suit, proceeding, inquiry or investigation before or brought by any court or governmental agency or body, domestic or foreign, now pending, or, to the knowledge of the Company, threatened, against or affecting the Company or any subsidiary, which is required to be disclosed in the Registration Statement (other than as disclosed therein), or which might reasonably be expected to result in a Material Adverse Effect, or which might reasonably be expected to materially and adversely affect the properties or assets thereof or the consummation of the transactions contemplated in this Agreement or the U.S. Purchase Agreement or the performance by the Company of its obligations hereunder and thereunder; the aggregate of all pending legal or governmental proceedings to which the Company or any subsidiary is a party or of which any of their respective property or assets is the subject which are not described in the Registration Statement, including ordinary routine litigation incidental to the business, could not reasonably be expected to result in a Material Adverse Effect.

(xiii) Accuracy of Exhibits. There are no contracts or documents which are required to be described in the Registration Statement or the Prospectuses or to be filed as exhibits thereto which have not been so described and filed as required, and the descriptions of all such contracts and documents in the Prospectuses are complete and accurate in all material respects.

(xiv) Possession of Intellectual Property. The Company and its subsidiaries own or possess, or can acquire on reasonable terms, adequate patents, patent rights, licenses, inventions, copyrights, know-how (including trade secrets and other unpatented and/or unpatentable proprietary or confidential information, systems or procedures), trademarks, service marks, trade names or other intellectual property (collectively, "Intellectual Property") necessary to carry on the business now operated by them, and neither the Company nor any of its subsidiaries has received any notice or is otherwise aware of any infringement of or conflict with asserted rights of others with respect to any Intellectual Property or of any facts or circumstances which would render any Intellectual Property invalid or inadequate to protect the interest of the Company or any of its subsidiaries therein, and which infringement or conflict (if the subject of any unfavorable decision, ruling or finding) or invalidity or inadequacy, singly or in the aggregate, would result in a Material Adverse Effect.

(xv) Absence of Further Requirements. No filing with, or authorization, approval, consent, license, order, registration,

9

qualification or decree of, any court or governmental authority or agency is necessary or required for the performance by the Company of its obligations under this Agreement or the U.S. Purchase Agreement, in connection with the offering, issuance or sale of the Securities hereunder or thereunder or the consummation of the transactions contemplated by this Agreement or the U.S. Purchase Agreement, except such as have been already obtained or as may be required under the 1933 Act or the 1933 Act Regulations or state or foreign securities laws.

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

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

10

continued possession of the leased or subleased premises under any such lease or sublease.

(xviii) Compliance with Cuba Act. The Company has complied with, and is and will be in compliance with, the provisions of that certain Florida act relating to disclosure of doing business with Cuba, codified as Section 517.075 of the Florida statutes, and the rules and regulations thereunder or is exempt therefrom.

(xix) Investment Company Act. The Company is not, and upon the issuance and sale of the Securities as herein contemplated and the application of the net proceeds therefrom as described in the Prospectuses will not be, an "investment company" or an entity "controlled" by an "investment company" as such terms are defined in the Investment Company Act of 1940, as amended (the "1940 Act").

(xx) Environmental Laws. Except as described in the Registration Statement and except as would not, singly or in the aggregate, result in a Material Adverse Effect, (A) neither the Company nor any of its subsidiaries is in violation of any federal, state, local or foreign statute, law, rule, regulation, ordinance, code, legally binding policy or rule of common law or any judicial or legally binding administrative interpretation thereof, including any judicial or administrative order, consent, decree or judgment, relating to pollution or protection of human health, the environment (including, without limitation, ambient air, surface water, groundwater, land surface or subsurface strata) or wildlife, including, without limitation, laws and regulations relating to the release or threatened release of chemicals, pollutants, contaminants, wastes, toxic substances, hazardous substances, petroleum or petroleum products (collectively, "Hazardous Materials") or to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials (collectively, "Environmental Laws"), (B) the Company and its subsidiaries have all permits, authorizations and approvals required under any applicable Environmental Laws (except for such permits, authorizations and approvals the absence of which would not result in a Material Adverse Effect) and are each in compliance with their requirements, (C) there are no pending or, to the knowledge of the Company, threatened administrative, regulatory or judicial actions, suits, demands, demand letters, claims, liens, notices of noncompliance or violation, investigation or proceedings relating to any Environmental Law against the Company or any of its subsidiaries and (D) there are no events or circumstances that might reasonably be expected to form the basis of an order for clean-up or remediation, or an action, suit or proceeding by any private party or governmental body or agency, against or affecting the Company or any of its

11

subsidiaries relating to Hazardous Materials or any Environmental Laws.

(xxi) Registration Rights. There are no persons with registration rights or other similar rights to have any securities registered pursuant to the Registration Statement or otherwise registered by the Company under the 1933 Act except as described in the Prospectuses. All applicable "piggy-back" registration rights otherwise applicable and entitling the persons holding such rights to have any securities so registered have been duly and validly waived or otherwise relinquished in respect of the Registration Statement and the transactions contemplated thereby.

(xxii) Taxes. The Company and each of its subsidiaries have filed all necessary federal, state, local and foreign income, payroll, franchise and other tax returns (after giving effect to extensions) and have paid all taxes shown as due thereon or with respect to any of its properties, except for taxes being contested in good faith for which adequate reserves have been provided, and there is no tax deficiency that has been, or to the knowledge of the Company is likely to be, asserted against the Company, any of its subsidiaries or any of their properties or assets that would result in a Material Adverse Effect.

(xxiii) Maintenance of Adequate Insurance. The Company and each of its subsidiaries is insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as is reasonably prudent in the business in which it is engaged or proposed to engage after giving effect to the transactions described in the Prospectuses; and the Company does not have any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that would not result in a Material Adverse Effect.

(xxiv) Merger. The Company and American Axle & Manufacturing of Michigan, Inc., a Michigan corporation ("AAMM"), had all corporate power and authority to carry out the merger of AAMM into the Company (the "Merger"), and the Company, AAMM and their respective stockholders have taken all action required by law and their respective charters and bylaws or otherwise to approve the Merger; the consummation of the Merger did not contravene any provision of applicable law or the respective charters or bylaws of the Company and AAMM or any provision of any material agreement or other material instrument binding upon the Company or AAMM or any order, writ, injunction or decree of any jurisdiction, court or governmental body, and no consent, approval, authorization or order of any court or governmental agency or body was required for the consummation of the Merger, except such as were obtained; the Merger became

12

effective on January 22, 1999, in accordance with the laws of Michigan and Delaware; and the Merger will not result in the recognition of any material liability under the Internal Revenue Code of 1986, as amended (the "Code") or otherwise for taxes for the Company or any of its subsidiaries.

Any certificate signed by any officer of the Company or any of its subsidiaries delivered to the Lead Managers or to counsel for the International Managers and the U.S. Underwriters shall be deemed a representation and warranty by the Company to each International Manager and each U.S. Underwriter as to the matters covered thereby.

SECTION 2. Sale and Delivery to International Managers; Closing.

(a) Initial International Securities. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company agrees to sell to each International Manager, severally and not jointly, and each International Manager, severally and not jointly, agrees to purchase from the Company, at the price per share set forth in Schedule B, that number of Initial International Securities set forth in Schedule A opposite the name of such International Manager, plus any additional number of Initial International Securities which such International Manager may become obligated to purchase pursuant to the provisions of Section 10 hereof, subject, in each case, to such adjustments among the International Managers as the Lead Managers in their sole discretion shall make to eliminate any sales or purchases of fractional securities.

(b) International Option Securities. In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company hereby grants an option to the International Managers, severally and not jointly, to purchase up to an additional 210,000 shares of Common Stock, at the price per share set forth in Schedule B, less an amount per share equal to any dividends or distributions declared by the Company and payable on the Initial International Securities but not payable on the International Option Securities. The option hereby granted will expire 30 days after the date hereof and may be exercised in whole or in part from time to time only for the purpose of covering over-allotments which may be made in connection with the offering and distribution of the Initial International Securities upon notice by the Global Coordinator to the Company setting forth the number of International Option Securities as to which the several International Managers are then exercising the option and the time and date of payment and delivery for such International Option Securities. Any such time and date of delivery (a "Date of Delivery") shall be determined by the Global Coordinator, but shall not be later than seven full business days

13

after the exercise of said option, nor in any event prior to the Closing Time, as hereinafter defined. If the option is exercised as to all or any portion of the International Option Securities, each of the International Managers, acting severally and not jointly, will purchase that proportion of the total number of International Option Securities then being purchased which the number of Initial International Securities set forth in Schedule A opposite the name of such International Underwriter bears to the total number of Initial International Securities, and the Company shall sell such number of International Option Securities, subject in each case to such adjustments as the Global Coordinator in its discretion shall make to eliminate any sales or purchases of fractional shares.

(c) Payment. Payment of the purchase price for, and delivery of certificates for, the Initial International Securities shall be made at the offices of Mayer Brown & Platt, 190 South LaSalle Street, Chicago, Illinois, or at such other place as shall be agreed upon by the Global Coordinator and the Company, at 9:00 A.M. (Eastern time) on the third (fourth, if the pricing occurs after 4:30 P.M. (Eastern time) on any given day) business day after the date hereof (unless postponed in accordance with the provisions of Section 10), or such other time not later than ten business days after such date as shall be agreed upon by the Global Coordinator and the Company (such time and date of payment and delivery being herein called "Closing Time").

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

Payment shall be made to the Company by wire transfer of immediately available funds to bank accounts designated by the Company, against delivery to the Lead Managers for the respective accounts of the International Managers of certificates for the International Securities to be purchased by them. It is understood that each International Manager has authorized the Lead Managers, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Initial International Securities and the International Option Securities, if any, which it has agreed to purchase. Merrill Lynch, individually and not as representative of the International Managers, may (but shall not be obligated to) make payment of the purchase price for the Initial International Securities or the International Option Securities, if any, to be purchased by any International Manager whose funds have not been received by the Closing Time or the relevant Date of

14

Delivery, as the case may be, but such payment shall not relieve such International Manager from its obligations hereunder.

(d) Denominations; Registration. Certificates for the Initial International Securities and the International Option Securities, if any, shall be in such denominations and registered in such names as the Lead Managers may request in writing at least one full business day before the Closing Time or the relevant Date of Delivery, as the case may be. The certificates for the Initial International Securities and the International Option Securities, if any, will be made available for examination and packaging by the Lead Managers in The City of New York not later than 10:00 A.M. (Eastern time) on the business day prior to the Closing Time or the relevant Date of Delivery, as the case may be.

SECTION 3. Covenants of the Company. The Company covenants with each International Manager as follows:

(a) Compliance with Securities Regulations and Commission Requests. The Company, subject to Section 3(b), will comply with the requirements of Rule 430A or Rule 434, as applicable, and will notify the Global Coordinator immediately, and confirm the notice in writing, (i) when any post-effective amendment to the Registration Statement shall become effective, or any supplement to the Prospectuses or any amended Prospectuses shall have been filed, (ii) of the receipt of any comments from the Commission, (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectuses or for additional information, and (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of any preliminary prospectus, or of the suspension of the qualification of the Securities for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes. The Company will promptly effect the filings necessary pursuant to Rule 424(b) and will take such steps as it deems necessary to ascertain promptly whether the form of prospectus transmitted for filing under Rule 424(b) was received for filing by the Commission and, in the event that it was not, it will promptly file such prospectus. The Company will make every reasonable effort to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible moment.

(b) Filing of Amendments. The Company will give the Global Coordinator notice of its intention to file or prepare any amendment to the Registration Statement (including any filing under Rule 462(b)), any Term Sheet or any amendment, supplement or revision to either the prospectus included in the Registration Statement at the time it became effective or to the Prospectuses, will furnish the Global Coordinator with copies of any such

15

documents a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Global Coordinator or counsel for the International Managers shall reasonably object in writing within a reasonable period of time.

(c) Delivery of Registration Statements. The Company has furnished or will deliver to the Lead Managers and counsel for the International Managers, without charge, signed copies of the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein) and signed copies of all consents and certificates of experts, and will also deliver to the Lead Manager without charge, a conformed copy of the Registration Statement as originally filed and of each amendment thereto (without exhibits) for each of the International Managers. The copies of the Registration Statement and each amendment thereto furnished to the International Managers will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

(d) Delivery of Prospectuses. The Company has delivered to each International Manager, without charge, as many copies of each preliminary prospectus as such International Manager reasonably requested, and the Company hereby consents to the use of such copies for purposes permitted by the 1933 Act. The Company will furnish to each International Manager, without charge, during the period when the International Prospectus is required to be delivered under the 1933 Act or the Securities Exchange Act of 1934 (the "1934 Act"), such number of copies of the International Prospectus (as amended or supplemented) as such International Manager may reasonably request. The International Prospectus and any amendments or supplements thereto furnished to the International Managers will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

(e) Continued Compliance with Securities Laws. The Company will comply with the 1933 Act and the 1933 Act Regulations so as to permit the completion of the distribution of the Securities as contemplated in this Agreement, the U.S. Purchase Agreement and in the Prospectuses. If at any time when a prospectus is required by the 1933 Act to be delivered in connection with sales of the Securities, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the International Managers or for the Company, to amend the Registration Statement or amend or supplement the Prospectuses in order that the Prospectuses will not include any untrue statements of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a

16

purchaser, or if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement the Prospectuses in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company will promptly prepare and file with the Commission, subject to Section 3(b), such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectuses comply with such requirements, and the Company will furnish to the International Managers such number of copies of such amendment or supplement as the International Managers may reasonably request.

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

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

(h) Use of Proceeds. The Company will use the net proceeds received by it from the sale of the Securities in the manner specified in the Prospectuses under "Use of Proceeds."

(i) Listing. The Company will use its best efforts to effect and maintain the listing of the Securities on the New York Stock Exchange and will file with the New York Stock Exchange all documents and notices required by the New York Stock Exchange of companies that have securities listed thereon.

(j) Restriction on Sale of Securities. During a period of 180 days from the date of the Prospectuses, the Company will not,

17

without the prior written consent of Merrill Lynch, (i) directly or indirectly, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of any share of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or file any registration statement under the 1933 Act with respect to any of the foregoing or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Common Stock, whether any such swap or transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (A) the Securities to be sold hereunder or under the U.S. Purchase Agreement, (B) grants of stock options and other awards pursuant to the terms of the Company's stock option plans in effect on the date hereof and described in the Prospectuses, (C) any shares of Common Stock issued by the Company upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof and referred to in the Prospectuses or (D) offers, sales and issuances of shares of Common Stock, options, rights or warrants to purchase or any securities convertible into or exercisable or exchangeable for Common Stock in connection with acquisitions of businesses, companies or assets by the Company so long as the recipients of such shares, options, rights, warrants or convertible securities are subject to the restrictions of this Section 3(j) until the expiration of such 180 day period.

(k) Reporting Requirements. The Company, during the period when the Prospectuses are required to be delivered under the 1933 Act or the 1934 Act, will file all documents required to be filed with the Commission pursuant to the 1934 Act within the time periods required by the 1934 Act and the rules and regulations of the Commission thereunder.

(l) Compliance with Rule 463. The Company will comply with the reporting requirements of Rule 463 of the 1933 Act Regulations.

The Company hereby agrees that it will ensure that the Reserved Securities will be restricted as required by the NASD or the NASD rules from sale, transfer, assignment, pledge or hypothecation for a period of three months following the date of effectiveness of the Registration Statement. The Underwriters will notify the Company as to which persons will need to be so restricted. At the request of the Underwriters, the Company will direct the transfer agent to place a stop transfer restriction upon such securities for such period of time. Should the Company release, or seek to release, from such restrictions any of the Reserved Securities, the Company agrees to reimburse the Underwriters for any reasonable expenses including, without

18

limitation, legal expenses they incur in connection with such release.

SECTION 4. Payment of Expenses.

SECTION 6. Indemnification.

(a) Indemnification of International Managers. The Company agrees to indemnify and hold harmless each International Manager and each person, if any, who controls any International Manager within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including the Rule 430A Information and the Rule 434 Information, if applicable, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus or the Prospectuses (or any amendment or supplement thereto), or the

23

omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company; and

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by Merrill Lynch), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that (A) this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any International Manager through the Lead Managers expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430A Information and the Rule 434 Information, if applicable, or any preliminary prospectus or the International Prospectus (or any amendment or supplement thereto) and (B) as to any preliminary prospectus, this indemnity agreement shall not inure to the benefit of any International Manager or any person, if any, who controls any International Manager within the meaning of
Section 15 of the 1933 Act or Section 20 of the 1934 Act on account of any loss, liability, claim, damage or expense arising from the fact that such International Manager sold Securities to a person to whom there was not sent or given, at or prior to the written confirmation of such sale, a copy of the International Prospectus (as then amended or supplemented) in any case where such delivery is required by the 1933 Act if the Company has previously furnished copies thereof to such International Manager in the quantities requested and the loss, liability, claim, damage or expense of such International Manager results from an untrue statement or omission of a material fact contained in such preliminary prospectus which the Company has sustained the burden of proving was corrected in the International Prospectus (as then amended or supplemented).

24

(b) Indemnification of Company, Directors and Officers. Each International Manager severally agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including the Rule 430A Information and the Rule 434 Information, if applicable, or any preliminary prospectus or the International Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by such International Manager through the Lead Managers expressly for use in the Registration Statement (or any amendment thereto) or such preliminary prospectus or the International Prospectus (or any amendment or supplement thereto).

(c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to
Section 6(a) above, counsel to the indemnified parties shall be selected by Merrill Lynch; and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this
Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or

25

consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel which are reimbursable under this Section 6 or Section 7, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement, which notice shall include a statement by the indemnified party that it proposes to enter into such settlement on such terms to the extent permitted by this Section 6(d), at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

(e) Indemnification for Reserved Securities. In connection with the offer and sale of the Reserved Securities, the Company agrees to indemnify and hold harmless the Underwriters from and against any and all losses, expenses and liabilities incurred by them as a result of (i) the failure of the designated employees or other persons to pay for and accept delivery of shares which, immediately following the effectiveness of the Registration Statement, were subject to a properly confirmed agreement to purchase and (ii) the violation of any securities laws of foreign jurisdictions where Reserved Securities have been offered.

SECTION 7. Contribution. If the indemnification provided for in
Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the International Managers on the other hand from the offering of the International Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the International Managers on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims,

26

damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company on the one hand and the International Managers on the other hand in connection with the offering of the International Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the International Securities pursuant to this Agreement (before deducting expenses) received by the Company and the total underwriting discount received by the International Managers, in each case as set forth on the cover of the International Prospectus, or, if Rule 434 is used, the corresponding location on the Term Sheet, bear to the aggregate initial public offering price of the International Securities as set forth on such cover.

The relative fault of the Company on the one hand and the International Managers on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the International Managers and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the International Managers agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the International Managers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section
7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no International Manager shall be required to contribute any amount in excess of the amount by which the total price at which the International Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such International Manager has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

27

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

For purposes of this Section 7, each person, if any, who controls an International Managers within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act shall have the same rights to contribution as such International Manager, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The International Managers' respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Initial International Securities set forth opposite their respective names in Schedule A hereto and not joint.

SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any International Manager or controlling person, or by or on behalf of the Company, and shall survive delivery of the Securities to the International Managers.

SECTION 9. Termination of Agreement.

(a) Termination; General. The Lead Managers may terminate this Agreement, by notice to the Company, at any time at or prior to Closing Time
(i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the International Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company or any of its subsidiaries, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Lead Managers, impracticable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange, or if trading generally on the New York Stock Exchange has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices

28

have been required, by the New York Stock Exchange or by order of the Commission, the NASD or any other governmental authority, or (iv) if a banking moratorium has been declared by Federal or New York authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7 and 8 shall survive such termination and remain in full force and effect.

SECTION 10. Default by One or More of the International Managers. If one or more of the International Managers shall fail at Closing Time or a Date of Delivery to purchase the International Securities which it or they are obligated to purchase under this Agreement (the "Defaulted Securities"), the Lead Managers shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting International Managers, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth. If, however, the Lead Manager shall not have completed such arrangements within such 24-hour period, then:

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

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

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

In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the International Managers to purchase and the Company to sell the relevant International Option Securities, as the case may be, either (i) the Lead Managers or

29

(ii) the Company shall have the right to postpone the Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectuses or in any other documents or arrangements. As used herein, the term "International Manager" includes any person substituted for a International Manager under this Section 10.

SECTION 11. Default by the Company. If the Company shall fail at Closing Time or at the Date of Delivery to sell the number of International Securities that it is obligated to sell hereunder, then this Agreement shall terminate without any liability on the part of any nondefaulting party; provided, however, that the provisions of Sections 1, 4, 6, 7 and 8 shall remain in full force and effect. No action taken pursuant to this Section shall relieve the Company from liability, if any, in respect of such default.

SECTION 12. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the International Managers shall be directed to the Lead Managers at Merrill Lynch, Sears Tower Building, Suite 5500, Chicago, Illinois 60606, attention of Michael O'Grady; and notices to the Company shall be directed to it at 1840 Holbrook Avenue, Detroit, Michigan 48212, attention of Patrick S. Lancaster, Esq.

SECTION 13. Parties. This Agreement shall inure to the benefit of and be binding upon the International Managers, the Company and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the International Managers the Company and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the International Managers, the Company and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any International Manager shall be deemed to be a successor by reason merely of such purchase.

SECTION 14. GOVERNING LAW AND TIME. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. EXCEPT AS OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

30

SECTION 15. Effect of Headings. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

31

Annex A

FORM OF ACCOUNTANTS' COMFORT LETTER PURSUANT TO SECTION 5(e)

We are independent public accountants with respect to the Company within the meaning of the 1933 Act and the applicable published 1933 Act Regulations

(i) in our opinion, the audited financial statements and the related financial statement schedules included in the Registration Statement and the Prospectus comply as to form in all material respects with the applicable accounting requirements of the 1933 Act and the published rules and regulations thereunder;

(ii) on the basis of procedures (but not an examination in accordance with generally accepted auditing standards) consisting of a reading of the unaudited interim consolidated financial statements of the Company for the three month periods ended March 31, 1997 and March 31, 1998 included in the Registration Statement and the Prospectus (collectively, the "Quarterly Financials"), a reading of the latest available unaudited interim consolidated financial statements of the Company, a reading of the minutes of all meetings of the stockholders and directors of the Company and its subsidiaries and the ____________ and ____________ Committees of the Board of Directors of the Company and any subsidiary committees since January 1, 1998, inquiries of certain officials of the Company and its subsidiaries responsible for financial and accounting matters, a review of interim financial information in accordance with standards established by the American Institute of Certified Public Accountants in Statement on Auditing Standards No. 71, Interim Financial Information ("SAS 71"), with respect to the three-month periods ended March 31, 1997 and March 31, 1998 and such other inquiries and procedures as may be specified in such letter, nothing came to our attention that caused us to believe that:

(A) the Quarterly Financials included in the Registration Statement and the Prospectus do not comply as to form in all material respects with the applicable accounting requirements of the 1933 Act and the 1933 Act Regulations or any material modifications should be made to the unaudited consolidated financial statements included in the Registration Statement and the Prospectus for them to be in conformity with generally accepted accounting principles;

(B) at [_________, 19___ and at] a specified date not more than five days prior to the date of this Agreement, there was any change in the ___________ of the Company and its subsidiaries or any decrease in the __________ of the Company and its subsidiaries or any increase in the __________ of the Company and its subsidiaries, in

A-1

each case as compared with amounts shown in the latest balance sheet included in the Registration Statement, except in each case for changes, decreases or increases that the Registration Statement discloses have occurred or may occur; or

(C) [for the period from _________, 19___ to _________, 19___ and ] for the period from _________, 19___ to a specified date not more than five days prior to the date of this Agreement, there was any decrease in _________, __________ or ___________, in each case as compared with the comparable period in the preceding year, except in each case for any decreases that the Registration Statement discloses have occurred or may occur;

(iii) based upon the procedures set forth in clause (ii) above and a reading of the Selected Financial Data included in the Registration Statement and a reading of the financial statements from which such data were derived, nothing came to our attention that caused us to believe that the Selected Financial Data included in the Registration Statement do not comply as to form in all material respects with the disclosure requirements of Item 301 of Regulation S-K of the 1933 Act, that the amounts included in the Selected Financial Data are not in agreement with the corresponding amounts in the audited consolidated financial statements for the respective periods or that the financial statements not included in the Registration Statement from which certain of such data were derived are not in conformity with generally accepted accounting principles;

(iv) we have compared the information in the Registration Statement under selected captions with the disclosure requirements of Regulation S-K of the 1933 Act and on the basis of limited procedures specified herein nothing came to our attention that caused us to believe that this information does not comply as to form in all material respects with the disclosure requirements of Items 302, 402 and 503(d), respectively, of Regulation S-K;

(v) based upon the procedures set forth in clause (ii) above, a reading of the unaudited financial statements of the Company for [the most recent period] that have not been included in the Registration Statement and a review of such financial statements in accordance with SAS 71, nothing came to our attention that caused us to believe that the unaudited amounts for _____________ for the [most recent period] do not agree with the amounts set forth in the unaudited consolidated financial statements for those periods or that such unaudited amounts were not determined on a basis substantially consistent with that of the corresponding amounts in the audited consolidated financial statements;

A-2

(vi) we are unable to and do not express any opinion on the Pro Forma Condensed Consolidated Financial Data (the "Pro Forma Statements) included in the Registration Statement or on the pro forma adjustments applied to the historical amounts included in the Pro Forma Statements; however, for purposes of this letter we have:

(A) read the Pro Forma Statements;

(B) performed [an audit] [a review in accordance with SAS 71] of the financial statements to which the pro forma adjustments were applied;

(C) made inquiries of certain officials of the Company who have responsibility for financial and accounting matters about the basis for their determination of the pro forma adjustments and whether the Pro Forma Statements comply as to form in all material respects with the applicable accounting requirements of Rule 11-02 of Regulation S-X; and

(D) proved the arithmetic accuracy of the application of the pro forma adjustments to the historical amounts in the Pro Forma Statements; and on the basis of such procedures and such other inquiries and procedures as specified herein, nothing came to our attention that caused us to believe that the Pro Forma Statements included in the Registration Statement do not comply as to form in all material respects with the applicable requirements of Rule 11-02 of Regulation S-X or that the pro forma adjustments have not been properly applied to the historical amounts in the compilation of those statements; and

(vii) in addition to the procedures referred to in clause (ii) above, we have performed other procedures, not constituting an audit, with respect to certain amounts, percentages, numerical data and financial information appearing in the Registration Statement, which are specified herein, and have compared certain of such items with, and have found such items to be in agreement with, the accounting and financial records of the Company.

AGREEMENT AND PLAN OF MERGER, made and entered into as of January 22, 1999, by and between AMERICAN AXLE & MANUFACTURING HOLDINGS, INC., a Delaware corporation ("Axle Delaware"), and AMERICAN AXLE & MANUFACTURING OF MICHIGAN, INC., a Michigan corporation ("Axle Michigan"). Axle Delaware and Axle Michigan are the "Constituent Corporations" to the Merger described below.

WHEREAS, the respective boards of directors of Axle Michigan and Axle Delaware have approved the merger of Axle Michigan with and into Axle Delaware (the "Merger") pursuant to the applicable provisions of the Michigan Business Corporation Act (the "MBCA") and the Delaware General Corporation Law (the "DGCL") on the terms hereinafter set forth and have approved this Agreement and Plan of Merger and authorized the execution hereof and recommended this Agreement and Plan of Merger to the shareholders of Axle Michigan and Axle Delaware, respectively;

NOW, THEREFORE, in consideration of the mutual covenants contained herein, the parties hereto agree as follows:

SECTION 1. The Merger; Outstanding Shares. (a) Upon the terms and subject to the conditions set forth in this Agreement, in accordance with the DGCL and the MBCA, the Merger will be effected and pursuant thereto Axle Michigan will be merged with and into Axle Delaware. At the Effective Time (as defined below), the separate corporate existence of Axle Michigan will cease and Axle Delaware will continue as the surviving corporation. After giving effect to the Merger and as the context requires, Axle Delaware is sometimes hereinafter referred to as the "Surviving Corporation".

(b) The authorized capital stock of Axle Michigan consists of 100,000 common shares, par value $.01 per share ("Axle Michigan Common Stock"), of which 8,227.15 shares are issued and outstanding on the date hereof, and 100,000 preferred shares, none of which are issued and outstanding. Each share of Axle Michigan Common Stock is entitled to vote. The number of shares of Axle Michigan Common Stock is subject to change before the Effective Time as a result of the issuance of such shares upon the exercise of stock options currently outstanding.

(c) The authorized capital stock of Axle Delaware consists of 100 shares of common stock, par value $.01 per share ("Axle Delaware Common Stock"), of which one share is issued and outstanding on the date hereof. Such share is entitled to vote. The number of outstanding shares of Axle Delaware will not change before the Effective Time.

SECTION 2. Closing; Effective Time. Unless this Agreement shall have been terminated and the transaction herein contemplated shall have been abandoned pursuant to Section 8, and subject to the satisfaction of the conditions set forth in Section 7, the parties hereto will cause the Merger to be consummated by filing (i) this Agreement or a certificate of merger (the "Delaware Certificate of Merger") with the Secretary of State of the State of Delaware, as


2

provided in the DGCL, and (ii) a certificate of merger (the "Michigan Certificate of Merger") with the Administrator, as provided in the MBCA, as early as possible after the satisfaction of the conditions set forth in Section
7. The Merger will become effective upon the later of the filing of the Delaware Certificate of Merger or the Michigan Certificate of Merger or at such later time as is provided in the Delaware Certificate of Merger and the Michigan Certificate of Merger as the parties hereto shall agree.

SECTION 3. Effects of the Merger.

(a) The Merger will have the effects as set forth in the applicable provisions of the DGCL and the MBCA.

(b) At the Effective Time, the certificate of incorporation shall be in the form of Exhibit A attached hereto and the bylaws shall be in the form attached to this Agreement.

(c) The officers and directors of Axle Michigan immediately prior to the Effective Time will, from and after the Effective Time, be the officers and directors of the Surviving Corporation. Each of such officers and directors shall hold office in accordance with the Surviving Corporation's certificate of incorporation and bylaws.

SECTION 4. Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of any holder of shares of Axle Michigan Common Stock or Axle Delaware Common Stock:

(a) Each share of Axle Michigan Common Stock issued and outstanding immediately prior to the Effective Time shall be converted into and become the right to receive 3,945 shares of Common Stock, par value $.01 per share ("Surviving Corporation Common Stock"), of the Surviving Corporation. As of the Effective Time, all such shares of Axle Michigan Common Stock shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each holder of a certificate representing any such shares of Axle Michigan Common Stock shall cease to have any rights with respect thereto, except the right to receive shares of Surviving Corporation Common Stock to be issued in consideration therefor as herein provided.

(b) Each share of Axle Delaware Common Stock issued and outstanding immediately prior to the Effective Time shall be canceled and retired without any consideration being payable in respect thereof.

SECTION 5. Stock Options; Stock Option Plans and Agreements.

(a) Each stock option granted by Axle Michigan (under or subject to any stock option plan or stock option agreement of Axle Michigan) and outstanding immediately prior to the Effective Time shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into and become a stock option to purchase, upon the same terms and conditions, the number of shares of the Surviving Corporation's Common Stock (subject to further adjustments as provided in the


3

governing stock option plan) which is equal to the number of shares of Axle Michigan Common Stock which the holder thereof would have received had such holder exercised the option in full immediately prior to the Effective Time (whether or not such option was then exercisable), multiplied by 3,945. The price per share payable upon exercise under each of said options shall (subject to future adjustments as provided in the governing stock option plan) be adjusted by dividing the exercise price of each option on the date immediately prior to the Effective Time by 3,945.

(b) All of Axle Michigan's stock option plans and stock option agreements, and all outstanding stock options thereunder, shall immediately prior to the Effective Time of the Merger be automatically amended to the extent necessary to permit continuance of such stock option plans and agreements and continuance and conversion of said stock options into those of the Surviving Corporation following the Merger, notwithstanding any provisions heretofore contained in such stock option plans or agreements providing for termination in the event of a merger in which American Axle & Manufacturing of Michigan, Inc. is not the Surviving Corporation. As of the Effective Time, Axle Delaware adopts and assumes each such plan and agreement as its own.

SECTION 6. Benefit and Incentive Plans. At the Effective Time, each employee benefit plan and incentive compensation plan to which Axle Michigan is then a party and all liabilities and obligations thereunder shall be assumed and adopted by, and continue to be the plan of, the Surviving Corporation. To the extent any employee benefit plan or incentive compensation plan of Axle Michigan or any of its subsidiaries provides for the issuance or purchase of, or otherwise relates to, Axle Michigan Common Stock, after the Effective Time such plan shall be deemed to provide for the issuance or purchase of, or otherwise relate to, the Surviving Corporation's Common Stock upon the same terms and conditions.

SECTION 7. Stockholder Approval Condition. This Agreement and Plan of Merger shall be submitted to the stockholders of Axle Michigan and Axle Delaware in accordance with the applicable provisions of the MBCA and DGCL, respectively, and the consummation of this Agreement and Plan of Merger and the Merger herein provided for are conditioned upon the approval and adoption hereof by the affirmative vote of the stockholders of Axle Michigan and Axle Delaware in accordance with applicable law.

SECTION 8. Abandonment; Termination. This Plan of Merger and the Merger herein contemplated may be abandoned upon the mutual agreement of the parties at any time prior to the Effective Time (before or after shareholder approval). This Agreement may be amended, modified or supplemented at any time (before or after shareholder approval) prior to the Effective Time of the Merger with the mutual consent of the Boards of Directors of Axle Michigan and Axle Delaware.

3

SIXTH: (1) To the fullest extent permitted by the laws of the State of Delaware:

(a) The corporation shall indemnify any person (and such person's heirs, executors or administrators) who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding (brought in the right of the corporation or otherwise), whether civil, criminal, administrative or investigative, and whether formal or informal, including appeals, by reason of the fact that such person is or was a director or officer of the corporation or, while a director or officer of the corporation, is or was serving at the request of the corporation as a director, officer, partner, trustee, employee or agent of another corporation, partnership, joint venture, trust, limited liability company or other enterprise, for and against all expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person or such heirs, executors or administrators in connection with such action, suit or proceeding, including appeals. Notwithstanding the preceding sentence, the corporation shall be required to indemnify a person described in such sentence in connection with any action, suit or proceeding (or part thereof) commenced by such person only if the commencement of such action, suit or proceeding (or part thereof) by such person was authorized by the Board of Directors of the corporation. The corporation may indemnify any person (and such person's heirs, executors or administrators) who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding (brought in the right of the corporation or otherwise), whether civil, criminal, administrative or investigative, and whether formal or informal, including appeals, 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 a director, officer, partner, trustee, employee or agent of another corporation, partnership, joint venture, trust, limited liability company or other enterprise, for and against all expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person or such heirs, executors or administrators in connection with such action, suit or proceeding, including appeals.

(b) The corporation shall promptly pay expenses incurred by any person described in the first sentence of subsection (a) of this Article Sixth,
Section (1) in defending any action, suit or proceeding in advance of the final disposition of such action, suit or proceeding, including appeals, upon presentation of appropriate documentation.

(c) The corporation may purchase and maintain insurance on behalf of any person described in subsection (a) of this Article Sixth, Section (1) against any liability asserted against such person, whether or not the corporation would have the power to indemnify such person against such liability under the provisions of this Article Sixth, Section (1) or otherwise.

(d) The provisions of this Article Sixth, Section (1) shall be applicable to all actions, claims, suits or proceedings made or commenced after the adoption hereof, whether arising from acts or omissions to act occurring before or after its adoption. The provisions of this Article Sixth, Section (1) shall be deemed to be a contract between the corporation and each director or officer who serves in such capacity at any time while this Article Sixth,
Section (1) and the relevant provisions of the laws of the State of Delaware and other applicable law, if any, are in effect, and any repeal or modification hereof shall not affect any rights or obligations then


4

existing with respect to any state of facts or any action, suit or proceeding then or theretofore existing, or any action, suit or proceeding thereafter brought or threatened based in whole or in part on any such state of facts. If any provision of this Article Sixth, Section (1) shall be found to be invalid or limited in application by reason of any law or regulation, it shall not affect the validity of the remaining provisions hereof. The rights of indemnification provided in this Article Sixth, Section (1) shall neither be exclusive of, nor be deemed in limitation of, any rights to which an officer, director, employee or agent may otherwise be entitled or permitted by contract, this Restated Certificate of Incorporation, vote of stockholders or directors or otherwise, or as a matter of law, both as to actions in such person's official capacity and actions in any other capacity while holding such office, it being the policy of the corporation that indemnification of any person whom the corporation is obligated to indemnify pursuant to the first sentence of subsection (a) of this Article Sixth, Section (1) shall be made to the fullest extent permitted by law.

(e) For purposes of this Article Sixth, references to "other enterprises" shall include employee benefit plans; references to "fines" shall include any excise taxes assessed on a person with respect to an 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.

(2) 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, except to the extent such exemption from liability or limitation thereof is not permitted under the General Corporation Law of the State of Delaware as the same exists or may hereafter be amended. Any amendment, modification or repeal of the foregoing sentence shall not adversely affect any right or protection of a director of the corporation hereunder in respect of any act or omission occurring prior to the time of such amendment, modification or repeal.

SEVENTH: (1) The business and affairs of the corporation shall be managed by or under the direction of a Board of Directors consisting of not less than three directors, the exact number of directors to be determined from time to time by resolution adopted by affirmative vote of a majority of the Board of Directors. The directors shall be divided into three classes designated Class I, Class II and Class III. Each class shall consist, as nearly as possible, of one-third of the total number of directors constituting the entire Board of Directors. Class I directors shall be originally elected for a term expiring at the succeeding annual meeting of stockholders, Class II directors shall be originally elected for a term expiring at the second succeeding annual meeting of stockholders, and Class III directors shall be originally elected for a term expiring at the third succeeding annual meeting of stockholders. At each succeeding annual meeting of stockholders following 1999, successors to the class of directors whose term expires at that annual meeting shall be elected for a term expiring at the third succeeding annual meeting. If the number of directors is changed, any increase or decrease shall be apportioned among the classes so as to maintain the number of directors in each class as nearly equal as possible, and any additional director of any class elected to fill a newly created directorship resulting from an increase in such class shall hold office for a term that shall coincide with the


5

remaining term of that class, but in no case shall a decrease in the number of directors remove or shorten the term of any incumbent director. A director shall hold office until the annual meeting for the year in which his term expires and until his successor shall be elected and shall qualify, subject, however, to prior death, resignation, retirement, disqualification or removal from office. Any newly created directorship on the Board of Directors that results from an increase in the number of directors and any vacancy occurring in the Board of Directors shall be filled only by a majority of the directors then in office, although less than a quorum, or by a sole remaining director. If any applicable provision of the General Corporation Law of the State of Delaware expressly confers power on stockholders to fill such a directorship at a special meeting of stockholders, such a directorship may be filled at such meeting only by the affirmative vote of at least 75 percent of the voting power of all shares of the corporation entitled to vote generally in the election of directors voting as a single class. Any director elected to fill a vacancy not resulting from an increase in the number of directors shall have the same remaining term as that of his predecessor. Directors may be removed only for cause, and only by the affirmative vote of at least 75 percent in voting power of all shares of the corporation entitled to vote generally in the election of directors, voting as a single class.

(2) Notwithstanding the foregoing, whenever the holders of any one or more series of Preferred Stock or Series Common Stock issued by the corporation shall have the right, voting separately as a series or separately as a class with one or more such other series, to elect directors at an annual or special meeting of stockholders, the election, term of office, removal, filling of vacancies and other features of such directorships shall be governed by the terms of this Certificate of Incorporation (including any certificate of designations relating to any series of Preferred Stock or Series Common Stock) applicable thereto, and such directors so elected shall not be divided into classes pursuant to this Article Seventh unless expressly provided by such terms.

EIGHTH: Any action required or permitted to be taken by the holders of the Common Stock of the corporation must be effected at a duly called annual or special meeting of such holders and may not be effected by any consent in writing by such holders. Except as otherwise required by law and subject to the rights of the holders of any series of Preferred Stock or Series Common Stock, special meetings of stockholders of the corporation may be called only by the Chief Executive Officer of the corporation or by the Board of Directors pursuant to a resolution approved by the Board of Directors.

NINTH: Notwithstanding anything contained in this Certificate of Incorporation to the contrary, the affirmative vote of the holders of at least 75 percent in voting power of all the shares of the corporation entitled to vote generally in the election of directors, voting together as a single class, shall be required to alter, amend or repeal Article Fifth, Article Seventh, Article Eighth or this Article Ninth or to adopt any provision inconsistent therewith.

STOCKHOLDERS

Section 1. The annual meeting of the stockholders of the corporation for the purpose of electing directors and for the transaction of such other business as may properly be brought before the meeting shall be held on such date, and at such time and place within or without the State of Delaware as may be designated from time to time by the Board of Directors.

Section 2. Special meetings of the stockholders shall be called at any time by the Secretary or any other officer, whenever directed by the Board of Directors or by the Chief Executive Officer. The purpose or purposes of the proposed meeting shall be included in the notice setting forth such call.

Section 3. Except as otherwise provided by law, notice of the time, place and, in the case of a special meeting, the purpose or purposes of the meeting of stockholders shall be delivered personally or mailed not earlier than sixty, nor less than ten days previous thereto, to each stockholder of record entitled to vote at the meeting at such address as appears on the records of the corporation.

Section 4. The holders of a majority in voting power of the stock issued and outstanding and entitled to vote thereat, present in person or represented by proxy, shall constitute a quorum at all meetings of the stockholders for the transaction of business, except as otherwise provided by statute or by the Certificate of Incorporation; but if at any regularly called meeting of stockholders there be less than a quorum present, the stockholders present may adjourn the meeting from time to time without further notice other than announcement at the meeting until a quorum shall be present or represented. At such adjourned meeting at which a quorum shall be present or represented any business may be transacted which might have been transacted at the original meeting. If the adjournment is for more than 30 days, or if, after the adjournment, a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting.

Section 5. The Chairman of the Board, or in the Chairman's absence or at the Chairman's direction, the President, or in the President's absence or at the President's direction, any officer of the corporation shall call all meetings of the stockholders to order and shall act as Chairman of such meeting. The Secretary of the corporation or, in such officer's absence, an


2

Assistant Secretary shall act as secretary of the meeting. If neither the Secretary nor an Assistant Secretary is present, the Chairman of the meeting shall appoint a secretary of the meeting. Unless otherwise determined by the Board of Directors prior to the meeting, the Chairman of the meeting shall determine the order of business and shall have the authority in his or her discretion to regulate the conduct of any such meeting, including, without limitation, by imposing restrictions on the persons (other than stockholders of the corporation or their duly appointed proxies) who may attend any such meeting, whether any stockholder or stockholders' proxy may be excluded from any meeting of stockholders based upon any determination by the Chairman, in his or her sole discretion, that any such person has unduly disrupted or is likely to disrupt the proceedings thereat, and the circumstances in which any person may make a statement or ask questions at any meeting of stockholders. The Chairman of the meeting shall have authority to adjourn any meeting of stockholders.

Section 6. At all meetings of stockholders, any stockholder entitled to vote thereat shall be entitled to vote in person or by proxy, but no proxy shall be voted after three years from its date, unless such proxy provides for a longer period. Without limiting the manner in which a stockholder may authorize another person or persons to act for the stockholder as proxy pursuant to the General Corporation Law of the State of Delaware, the following shall constitute a valid means by which a stockholder may grant such authority: (1) a stockholder may execute a writing authorizing another person or persons to act for the stockholder as proxy, and execution of the writing may be accomplished by the stockholder or the stockholder's authorized officer, director, employee or agent signing such writing or causing his or her signature to be affixed to such writing by any reasonable means including, but not limited to, by facsimile signature; or (2) a stockholder may authorize another person or persons to act for the stockholder as proxy by transmitting or authorizing the transmission of a telegram, cablegram, or other means of electronic transmission to the person who will be the holder of the proxy or to a proxy solicitation firm, proxy support service organization or like agent duly authorized by the person who will be the holder of the proxy to receive such transmission, provided that any such telegram, cablegram or other means of electronic transmission must either set forth or be submitted with information from which it can be determined that the telegram, cablegram or other electronic transmission was authorized by the stockholder. If it is determined that such telegrams, cablegrams or other electronic transmissions are valid, the judge or judges of stockholder votes or, if there are no such judges, such other persons making that determination shall specify the information upon which they relied.

Any copy, facsimile telecommunication or other reliable reproduction of the writing or transmission created pursuant to the preceding paragraph of this Section 6 may be substituted or used in lieu of the original writing or transmission for any and all purposes for which the original writing or transmission could be used, provided that such copy, facsimile telecommunication or other reproduction shall be a complete reproduction of the entire original writing or transmission.

Proxies shall be filed with the Secretary of the meeting prior to or at the commencement of the meeting to which they relate.

Section 7. When a quorum is present at any meeting, the vote of the holders of a majority in voting power of the stock present in person or represented by proxy and entitled to vote on the matter shall decide any question brought before such meeting, unless the question is one upon


3

which by express provision of statute or of the Certificate of Incorporation or these By-Laws, a different vote is required, in which case such express provision shall govern and control the decision of such question.

Section 8. In order that the corporation may determine the stockholders (a) entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, or (b) entitled to consent to corporate action in writing without a meeting, or (c) entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted, and which record date (i) in the case of clause (a) above, shall not be more than sixty nor less than ten days before the date of such meeting, (ii) in the case of clause (b) above, shall not be more than ten days after the date upon which the resolution fixing the record date is adopted by the board of directors, and (iii) in the case of clause (c) above, shall not be more than sixty days prior to such action. If for any reason the Board of Directors shall not have fixed a record date for any such purpose, the record date for such purpose shall be determined as provided by law. Only those stockholders of record on the date so fixed or determined shall be entitled to any of the foregoing rights, notwithstanding the transfer of any such stock on the books of the corporation after any such record date so fixed or determined.

Section 9. The officer who has charge of the stock ledger of the corporation shall prepare and make at least ten days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least ten days prior to the meeting, either at a place within the city where the meeting is to be held, which place shall be specified in the notice of meeting, or, if not so specified, at the place where the meeting is to be held. The list shall also be produced at the time and kept at the place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present.

Section 10. The Board of Directors, in advance of all meetings of the stockholders, shall appoint one or more judges of stockholder votes, who may be stockholders or their proxies, but not directors of the corporation or candidates for office. In the event that the Board of Directors fails to so appoint judges of stockholder votes or, in the event that one or more judges of stockholder votes previously designated by the Board of Directors fails to appear or act at the meeting of stockholders, the Chairman of the meeting may appoint one or more judges of stockholder votes to fill such vacancy or vacancies. Judges of stockholder votes appointed to act at any meeting of the stockholders, before entering upon the discharge of their duties, shall be sworn faithfully to execute the duties of judge of stockholder votes with strict impartiality and according to the best of their ability and the oath so taken shall be subscribed by them. Judges of stockholder votes shall, subject to the power of the Chairman of the meeting to open and close the polls, take charge of the polls, and, after the voting, shall make a certificate of the result of the vote taken.

Section 11. (A) Annual Meetings of Stockholders. (1) Nominations of persons for election to the Board of Directors of the corporation and the proposal of business to be considered by the stockholders may be made at an annual meeting of stockholders (a) pursuant to the corporation's notice of meeting delivered pursuant to Article 1, Section 3 of these By-Laws, (b) by or at the direction of the Chairman of the Board or (c) by any stockholder of the corporation who is entitled to vote at the meeting, who complied with the notice procedures set forth in subparagraphs (2) and (3) of this paragraph (A) of this By-Law and who was a stockholder of record at the time such notice is delivered to the Secretary of the corporation.

(2) For nominations or other business to be properly brought before an annual meeting by a stockholder pursuant to clause (c) of paragraph (A)(1) of this By-Law, the stockholder must have given timely notice thereof in writing to the Secretary of the corporation, and, in the case of business other than nominations, such other business must be a proper matter for stockholder action. To be timely, a stockholder's notice shall be delivered to the Secretary at the principal executive offices of the corporation not less than seventy days nor more than ninety days prior to the first anniversary of the preceding year's annual meeting; provided, however, that in the event that the date of the annual meeting is advanced by more than twenty days, or delayed by more than seventy days, from such anniversary date, notice by the stockholder to be timely must be so delivered not earlier than the ninetieth day prior to such annual meeting and not later than the close of business on the later of the seventieth day prior to such annual meeting or the tenth day following the day on which public announcement of the date of such meeting is first made. Such stockholder's notice shall set forth (a) as to each person whom the stockholder proposes to nominate for election or re-election as a director all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors, or is otherwise required, in each case pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), including such person's written consent to being named in the proxy statement as a nominee and to serving as a director if elected; (b) as to any other business that the stockholder proposes to bring before the meeting, a brief description of the business desired to be brought before the meeting, the reasons for conducting such business at the meeting and any material interest in such business of such stockholder and the beneficial owner, if any, on whose behalf the proposal is made; and (c) as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination or proposal is made (i) the name and address of such stockholder, as they appear on the corporation's books, and of such beneficial owner and (ii) the class and number of shares of the corporation which are owned beneficially and of record by such stockholder and such beneficial owner.

(3) Notwithstanding anything in the second sentence of paragraph (A)(2) of this By-Law to the contrary, in the event that the number of directors to be elected to the Board of Directors of the corporation is increased and there is no public announcement naming all of the nominees for director or specifying the size of the increased Board of Directors made by the corporation at least eighty days prior to the first anniversary of the preceding year's annual meeting, a stockholder's notice required by this By-Law shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be delivered to the Secretary at the principal executive offices of the corporation not later than the close of business on the tenth day following the day on which such public announcement is first made by the corporation.


5

(B) Special Meetings of Stockholders. Only such business shall be conducted at a special meeting of stockholders as shall have been brought before the meeting pursuant to the corporation's notice of meeting pursuant to Article I, Section 2 of these By-Laws. Nominations of persons for election to the Board of Directors may be made at a special meeting of stockholders at which directors are to be elected pursuant to the corporation's notice of meeting (a) by or at the direction of the Board of Directors or (b) by any stockholder of the corporation who is entitled to vote at the meeting, who complies with the notice procedures set forth in this By-Law and who is a stockholder of record at the time such notice is delivered to the Secretary of the corporation. Nominations by stockholders of persons for election to the Board of Directors may be made at such a special meeting of stockholders if the stockholder's notice as required by paragraph (A)(2) of this By-Law shall be delivered to the Secretary at the principal executive offices of the corporation not earlier than the ninetieth day prior to such special meeting and not later than the close of business on the later of the seventieth day prior to such special meeting or the tenth day following the day on which public announcement is first made of the date of the special meeting and of the nominees proposed by the Board of Directors to be elected at such meeting.

(C) General. (1) Only persons who are nominated in accordance with the procedures set forth in this By-Law shall be eligible to serve as directors and only such business shall be conducted at a meeting of stockholders as shall have been brought before the meeting in accordance with the procedures set forth in this By-Law. Except as otherwise provided by law, the Certificate of Incorporation or these By-Laws, the Chairman of the meeting shall have the power and duty to determine whether a nomination or any business proposed to be brought before the meeting was made in accordance with the procedures set forth in this By-Law and, if any proposed nomination or business is not in compliance with this By-Law, to declare that such defective nomination shall be disregarded or that such proposed business shall not be transacted.

(2) For purposes of this By-Law, "public announcement" shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press or comparable national news service or in a document publicly filed by the corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act.

(3) For purposes of this By-Law, no adjournment nor notice of adjournment of any meeting shall be deemed to constitute a new notice of such meeting for purposes of this Section 11, and in order for any notification required to be delivered by a stockholder pursuant to this Section 11 to be timely, such notification must be delivered within the periods set forth above with respect to the originally scheduled meeting.

(4) Notwithstanding the foregoing provisions of this By-Law, a stockholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder with respect to the matters set forth in this By-Law. Nothing in this By-Law shall be deemed to affect any rights of stockholders to request inclusion of proposals in the corporation's proxy statement pursuant to Rule 14a-8 under the Exchange Act.

ARTICLE II.

BOARD OF DIRECTORS

Section 1. The Board of Directors of the corporation shall consist of such number of directors, not less than three, as shall from time to time be fixed exclusively by resolution of the Board of Directors. The directors shall be divided into three classes in the manner set forth in the Certificate of Incorporation of the corporation, each class to be elected for the term set forth therein. Directors shall (except as hereinafter provided for the filling of vacancies and newly created directorships) be elected by the holders of a plurality of the voting power present in person or represented by proxy and entitled to vote. A majority of the total number of directors then in office (but not less than one-third of the number of directors constituting the entire Board of Directors) shall constitute a quorum for the transaction of business and, except as otherwise provided by law or by the corporation's Certificate of Incorporation, the act of a majority of the directors present at any meeting at which there is a quorum shall be the act of the Board of Directors. Directors need not be stockholders.

Section 2. Newly created directorships in the Board of Directors that result from an increase in the number of directors and any vacancy occurring in the Board of Directors shall be filled only by a majority of the directors then in office, although less than a quorum, or by a sole remaining director; and the directors so chosen shall hold office for a term as set forth in the Certificate of Incorporation of the corporation. If any applicable provision of the General Corporation Law of the State of Delaware expressly confers power on stockholders to fill such a directorship at a special meeting of stockholders, such a directorship may be filled at such meeting only by the affirmative vote of at least 75 percent in voting power of all shares of the corporation entitled to vote generally in the election of directors, voting as a single class.

Section 3. Meetings of the Board of Directors shall be held at such place within or without the State of Delaware as may from time to time be fixed by resolution of the Board or as may be specified in the notice of any meeting. Regular meetings of the Board of Directors shall be held at such times as may from time to time be fixed by resolution of the Board and special meetings may be held at any time upon the call of the Chairman of the Board, the President or a majority of the directors, by oral, or written notice including, telegraph, telex or transmission of a telecopy, e-mail or other means of transmission, duly served on or sent or mailed to each director to such director's address or telecopy number as shown on the books of the corporation not less than one day before the meeting. The notice of any meeting need not specify the purposes thereof. A meeting of the Board may be held without notice immediately after the annual meeting of stockholders at the same place at which such meeting is held. Notice need not be given of regular meetings of the Board held at times fixed by resolution of the Board. Notice of any meeting need not be given to any director who shall attend such meeting in person (except when the director attends a meeting for the express purpose of objecting at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened), or who shall waive notice thereof, before or after such meeting, in writing.

Section 4. Notwithstanding the foregoing, whenever the holders of any one or more series of Preferred Stock or Series Common Stock issued by the corporation shall have the right,


7

voting separately by series, to elect directors at an annual or special meeting of stockholders, the election, term of office, removal, filling of vacancies and other features of such directorships shall be governed by the terms of the Certificate of Incorporation applicable thereto, and such directors so elected shall not be divided into classes pursuant to Article SEVENTH of the Certificate of Incorporation unless expressly provided by such terms. The number of directors that may be elected by the holders of any such series of Preferred Stock or Series Common Stock shall be in addition to the number fixed by or pursuant to the By-Laws. Except as otherwise expressly provided in the terms of such series, the number of directors that may be so elected by the holders of any such series of stock shall be elected for terms expiring at the next annual meeting of stockholders and without regard to the classification of the members of the Board of Directors as set forth in Section 1 hereof, and vacancies among directors so elected by the separate vote of the holders of any such series of Preferred Stock or Series Common Stock shall be filled by the affirmative vote of a majority of the remaining directors elected by such series, or, if there are no such remaining directors, by the holders of such series in the same manner in which such series initially elected a director.

Section 5. If at any meeting for the election of directors, the corporation has outstanding more than one class of stock, and one or more such classes or series thereof are entitled to vote separately as a class, and there shall be a quorum of only one such class or series of stock, that class or series of stock shall be entitled to elect its quota of directors notwithstanding absence of a quorum of the other class or series of stock.

Section 6. The Board of Directors may designate three or more directors to constitute an executive committee, one of whom shall be designated Chairman of such committee. The members of such committee shall hold such office until the next election of the Board of Directors and until their successors are elected and qualify. Any vacancy occurring in the committee shall be filled by the Board of Directors. Regular meetings of the committee shall be held at such times and on such notice and at such places as it may from time to time determine. The committee shall act, advise with and aid the officers of the corporation in all matters concerning its interest and the management of its business, and shall generally perform such duties and exercise such powers as may from time to time be delegated to it by the Board of Directors, and shall have authority to exercise all the powers of the Board of Directors, so far as may be permitted by law, in the management of the business and the affairs of the corporation whenever the Board of Directors is not in session or whenever a quorum of the Board of Directors fails to attend any regular or special meeting of such Board. The committee shall have power to authorize the seal of the corporation to be affixed to all papers which are required by the Delaware General Corporation Law to have the seal affixed thereto. The fact that the executive committee has acted shall be conclusive evidence that the Board of Directors was not in session at such time or that a quorum of the Board had failed to attend the regular or special meeting thereof.

The executive committee shall keep regular minutes of its transactions and shall cause them to be recorded in a book kept in the office of the corporation designated for that purpose, and shall report the same to the Board of Directors at their regular meeting. The committee shall make and adopt its own rules for the government thereof and shall elect its own officers.

Section 7. The Board of Directors may from time to time establish such other committees to serve at the pleasure of the Board which shall be comprised of such members of the


8

Board and have such duties as the Board shall from time to time establish. Any director may belong to any number of committees of the Board. The Board may also establish such other committees with such members (whether or not directors) and such duties as the Board may from time to time determine.

Section 8. Unless otherwise restricted by the Certificate of Incorporation or these By-Laws, any action required or permitted to be taken at any meeting of the Board of Directors or of any committee thereof may be taken without a meeting if all members of the Board or committee, as the case may be, consent thereto in writing, and the writing or writings are filed with the minutes of proceedings of the Board of Directors.

Section 9. The members of the Board of Directors or any committee thereof may participate in a meeting of such Board or committee, as the case may be, by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other, and participation in a meeting pursuant to this subsection shall constitute presence in person at such a meeting.

Section 10. The Board of Directors may establish policies for the compensation of directors and for the reimbursement of the expenses of directors, in each case, in connection with services provided by directors to the corporation.

ARTICLE III.

OFFICERS

Section 1. The Board of Directors, as soon as may be after each annual meeting of the stockholders, shall elect officers of the corporation, including a Chairman of the Board or President, a Chief Financial Officer and a Secretary. The Board of Directors may also from time to time elect such other officers (including one or more Vice Presidents, a Treasurer, one or more Assistant Vice Presidents, one or more Assistant Secretaries and one or more Assistant Treasurers) as it may deem proper or may delegate to any elected officer of the corporation the power to appoint and remove any such other officers and to prescribe their respective terms of office, authorities and duties. Any Vice President may be designated Executive, Senior or Corporate, or may be given such other designation or combination of designations as the Board of Directors may determine. Any two or more offices may be held by the same person.

Section 2. All officers of the corporation elected by the Board of Directors shall hold office for such term as may be determined by the Board of Directors or until their respective successors are chosen and qualified. Any officer may be removed from office at any time either with or without cause by the affirmative vote of a majority of the members of the Board then in office, or, in the case of appointed officers, by any elected officer upon whom such power of removal shall have been conferred by the Board of Directors.

Section 3. Each of the officers of the corporation elected by the Board of Directors or appointed by an officer in accordance with these By-laws shall have the powers and duties


9

prescribed by law, by the By-Laws or by the Board of Directors and, in the case of appointed officers, the powers and duties prescribed by the appointing officer, and, unless otherwise prescribed by the By-Laws or by the Board of Directors or such appointing officer, shall have such further powers and duties as ordinarily pertain to that office. The Chairman of the Board or the President, as determined by the Board of Directors, shall be the Chief Executive Officer and shall have the general direction of the affairs of the corporation.

Section 4. Unless otherwise provided in these By-Laws, in the absence or disability of any officer of the corporation, the Board of Directors may, during such period, delegate such officer's powers and duties to any other officer or to any director and the person to whom such powers and duties are delegated shall, for the time being, hold such office.

ARTICLE IV.

CERTIFICATES OF STOCK

Section 1. The shares of stock of the corporation shall be represented by certificates, provided that the Board of Directors may provide by resolution or resolutions that some or all of any or all classes or series of the corporation's stock shall be uncertificated shares. Any such resolution shall not apply to shares represented by a certificate until such certificate is surrendered to the corporation. Notwithstanding the adoption of such a resolution by the Board of Directors, every holder of stock represented by certificates and upon request every holder of uncertificated shares shall be entitled to have a certificate signed by, or in the name of the corporation by the Chairman of the Board of Directors, or the President or a Vice President, and by the Treasurer or an Assistant Treasurer or the Secretary or an Assistant Secretary of the corporation, or as otherwise permitted by law, representing the number of shares registered in certificate form. Any or all the signatures on the certificate may be a facsimile.

Section 2. Transfers of stock shall be made on the books of the corporation by the holder of the shares in person or by such holder's attorney upon surrender and cancellation of certificates for a like number of shares, or as otherwise provided by law with respect to uncertificated shares.

Section 3. No certificate for shares of stock in the corporation shall be issued in place of any certificate alleged to have been lost, stolen or destroyed, except upon production of such evidence of such loss, theft or destruction and upon delivery to the corporation of a bond of indemnity in such amount, upon such terms and secured by such surety, as the Board of Directors in its discretion may require.

Borrower and its Subsidiaries, provided that any such pro forma increase or decrease shall be without duplication for net cost savings or additional net costs actually realized during such period and already included in the Borrower and its Subsidiaries' consolidated net income, plus, to the extent deducted in computing the consolidated net income or loss of such Acquired Entity or Business or Sold Entity or Business, without duplication, the sum of (a) income tax expense, (b) gross interest expense (including interest-equivalent costs associated with any receivables financings, whether accounted for as interest expense or loss on the sale of receivables), (c) depreciation and amortization expense, (d) any special charges (including any fees or expenses incurred in connection with the applicable acquisition) and any extraordinary or nonrecurring losses and (e) other non-cash items reducing consolidated net income (including any non-cash items resulting from purchase accounting adjustments), minus, to the extent added in computing the consolidated net income of such Acquired Entity or Business or Sold Entity or Business for such period, without duplication, (i) interest income, (ii) extraordinary or nonrecurring gains and (iii) other noncash items increasing consolidated net income.

"Adjusted EBITDA" shall mean, for any period, EBITDA for such period, calculated by (a) including in the determination thereof the Acquired EBITDA of any Person, property, business or asset in the Borrower's or any Subsidiary's line of business acquired pursuant to a transaction permitted under Section 6.04 and not subsequently sold, transferred or otherwise disposed of (but not including the Acquired EBITDA of any related person, property, business or assets to the extent not so acquired) by the Borrower or any Subsidiary during such period (each such Person, property, business or asset in the Borrower's or any Subsidiary's line of business acquired and not subsequently so disposed of, an "Acquired Entity or Business"), based on the actual Acquired EBITDA of such Acquired Entity or Business for such period (including the portion thereof occurring prior to such acquisition) and (b) excluding in the determination thereof the Acquired EBITDA of any Person, property, business or asset sold, transferred or otherwise disposed of by the Borrower or any Subsidiary during such period (each such Person, property, business or asset so sold or disposed of, a "Sold Entity or Business") based on the actual Acquired EBITDA of such Sold Entity or Business for such period (including the portion thereof occurring prior to such sale, transfer or disposition)." Notwithstanding the foregoing, for purposes of determining compliance with Section 6.11, Adjusted EBITDA shall not include the Acquired EBITDA (including any pro forma adjustment to the consolidated net income or loss of the Borrower and its Subsidiaries included therein) of any Acquired Entity or Business for any period prior to the fiscal quarter of the Borrower in which such Acquired Entity or Business was acquired.

"Adjusted Net Leverage Ratio" shall mean, on any date, the ratio of (a) Total Net Debt as of such date to (b) Adjusted EBITDA for the period of four consecutive fiscal quarters of the Borrower most recently ended as of such date, all determined on a consolidated basis in accordance with GAAP provided that, solely for purposes of determining whether the Adjusted Net Leverage Ratio as of the end of any four fiscal-quarter period that includes the fiscal quarter ended September 30, 1998, is in compliance with Section 6.12, there shall be added to the amount determined pursuant to clause (b), in the case of any such four fiscal-quarter period ending on or before March 31, 1999, an


3

additional $71,192,000, and, in the case of the four fiscal-quarter period ending on June 30, 1999, an additional $42,018,000.

"Permitted Subordinated Debt" means Indebtedness of the Borrower (and Guarantees of such Indebtedness by AAMM and the Subsidiaries) that contains subordination and subsidiary guarantee release provisions substantially in the form of Exhibit L, provided that (a) such Permitted Subordinated Debt accrues interest at a fixed rate determined in good faith by the Board of Directors of the Borrower to be a market rate of interest for such Permitted Subordinated Debt at the time of issuance thereof or, in the case of a bridge loan, at a floating rate determined based on a formula with a base rate, spreads and interest rate step-ups that are determined in good faith by the Board of Directors of the Borrower to be market rates of interest and interest rate step-up levels for such Permitted Subordinated Debt at the time of issuance thereof, (b) such Permitted Subordinated Debt is created under agreements or instruments (i) imposing covenants on AAMM, the Borrower and the Subsidiaries, (ii) containing a definition of change of control and
(iii) containing events of default and other provisions not materially more restrictive than the covenants imposed in, the change of control definition used in and the events of default and other provisions contained in this Agreement, (c) no scheduled principal payments are due, or, if due, are not automatically extended if unpaid, on such Permitted Subordinated Debt on a date that is earlier than six months after the Tranche B Maturity Date, (d) such Permitted Subordinated Debt is unsecured, (e) neither AAMM nor any Subsidiary shall Guarantee such Permitted Subordinated Debt unless (i) AAMM or such Subsidiary also has Guaranteed the Obligations and (ii) such Guarantee of such Permitted Subordinated Debt is subordinated to such Guarantee of the Obligations on terms no less favorable to the Lenders than the subordination provisions of the Permitted Subordinated Debt, (f) the terms of such Permitted Subordinated Debt do not require the maintenance or achievement of any financial performance standards other than as a condition to the taking of specified actions and (g) such Permitted Subordinated Debt contains other customary provisions that are reasonably satisfactory to the Administrative Agent.

"Sold Entity or Business" has the meaning assigned to such term in the definition of the term Adjusted EBITDA.;

(ii) by inserting immediately before the period at the end of the definition of the term "Cash Interest Expense" the following text: ", provided that there shall be included or excluded, as applicable, in determining Cash Interest Expense for any period the cash interest expense (calculated in the same manner as Cash Interest Expense is calculated) of any Acquired Entity or Business or Sold Entity or Business acquired or sold, as applicable, during such period for the period commencing on the first day of the fiscal quarter of the Borrower in which such Acquired Entity or Business was acquired through the end of the applicable test period (or, in the case of the sale of any Sold Entity or Business, for the applicable test period) assuming any Indebtedness incurred or repaid in connection with the acquisition or sale had been incurred or repaid on such first day (or, in the case of any such sale, on the first day of such test period)".

(e) Section 6.04(m) of the Credit Agreement is hereby amended by (i) replacing the phrase "not to exceed $100,000,000" with the phrase "not to exceed $200,000,000", (ii) replacing the phrase "at least 80%" in clause (i) of the proviso thereto with the phrase "at least 50%" and (iii) inserting in clause (ii) of the proviso thereto after the phrase "other costs and expenses" the phrase "(and fund working capital needs)".

The Committee is authorized to interpret the Plan, to establish, amend and rescind any rules and regulations relating to the Plan, and to make any other determinations that it deems necessary or desirable for the administration of the Plan. The Committee may correct any defect or supply any omission or reconcile any inconsistency in

2. Pursuant to Section 9(a) of the Plan, the number of Shares to equal 1,500,000 after the conversion of Shares pursuant to the proposed merger of the Company into American Axle & Manufacturing Holdings, Inc.


4

the Plan in the manner and to the extent the Committee deems necessary or desirable. Any decision of the Committee in the interpretation and administration of the Plan, as described herein, shall lie within its sole and absolute discretion and shall be final, conclusive and binding on all parties concerned (including, but not limited to, Participants and their beneficiaries or successors). The Committee shall require payment of any amount it may determine to be necessary to withhold for federal, state, local or other taxes as a result of the exercise of an Award. Unless the Committee specifies otherwise, the Participant may elect to pay a portion or all of such withholding taxes by (a) delivery in Shares or (b) having Shares withheld by the Company from any Shares that would have otherwise been received by the Participant.

5. Limitations

No Award may be granted under the Plan after the tenth anniversary of the Effective Date, but Awards theretofore granted may extend beyond that date.

6. Terms and Conditions of Options

Options granted under the Plan shall be, as determined by the Committee, non-qualified or incentive stock options for federal income tax purposes, as evidenced by the related Award agreements, and shall be subject to the foregoing and the following terms and conditions and to such other terms and conditions, not inconsistent therewith, as the Committee shall determine:

(a) Option Price. The Option Price per Share shall be determined by the Committee, but shall not be less than 100% of the Fair Market Value of the Shares on the date an Option is granted.

(b) Exercisability. Options granted under the Plan shall be exercisable at such time and upon such terms and conditions as may be determined by the Committee, but in no event shall an Option be exercisable more than ten years after the date it is granted.

(c) Exercise of Options. Except as otherwise provided in the Plan or in an Award agreement, an Option may be exercised for all, or from time to time any part, of the Shares for which it is then exercisable. For purposes of Section 6 of the Plan, the exercise date of an Option shall be the later of the date a notice of exercise is received by the Company and, if applicable, the date payment is received by the Company pursuant to clauses (i), (ii) or
(iii) in the following sentence. The purchase price for the Shares as to which an Option is exercised shall be paid to the Company in full at the time of exercise at the election of the Participant (i) in cash, (ii) in Shares having a Fair Market Value equal to the aggregate Option Price for the Shares being purchased and satisfying such other requirements as may be imposed by the Committee; provided, that such Shares have been held by the Participant for no less than six months, (iii) partly in cash and partly in such Shares or (iv) through the delivery of irrevocable instruments to a broker to deliver promptly to the Company an amount equal to the aggregate option price for the shares being purchased. No Participant shall have any rights to dividends or other rights of a stockholder with respect to Shares subject to an Option until the Participant has given written


5

notice of exercise of the Option, paid in full for such Shares and, if applicable, has satisfied any other conditions imposed by the Committee pursuant to the Plan.

(d) ISOs. The Committee may grant Options under the Plan that are intended to be ISOs. Such ISOs shall comply with the requirements of
Section 422 of the Code (or any successor section thereto). No ISO may be granted to any Participant who at the time of such grant, owns more than ten percent of the total combined voting power of all classes of stock of the Company or of any Subsidiary, unless (i) the Option Price for such ISO is at least 110% of the Fair Market Value of a Share on the date the ISO is granted and (ii) the date on which such ISO terminates is a date not later than the day preceding the fifth anniversary of the date on which the ISO is granted. Any Participant who disposes of Shares acquired upon the exercise of an ISO either
(i) within two years after the date of grant of such ISO or (ii) within one year after the transfer of such Shares to the Participant, shall notify the Company of such disposition and of the amount realized upon such disposition.

7. Terms and Conditions of Stock Appreciation Rights

(a) Grants. The Committee also may grant (i) a Stock Appreciation Right independent of an Option or (ii) a Stock Appreciation Right in connection with an Option, or a portion thereof. A Stock Appreciation Right granted pursuant to clause (ii) of the preceding sentence (A) may be granted at the time the related Option is granted or at any time prior to the exercise or cancellation of the related Option, (B) shall cover the same Shares covered by an Option (or such lesser number of Shares as the Committee may determine) and
(C) shall be subject to the same terms and conditions as such Option except for such additional limitations as are contemplated by this Section 8 (or such additional limitations as may be included in an Award agreement).

(b) Terms. The exercise price per Share of a Stock Appreciation Right shall be an amount determined by the Committee but in no event shall such amount be less than the greater of (i) the Fair Market Value of a Share on the date the Stock Appreciation Right is granted or, in the case of a Stock Appreciation Right granted in conjunction with an Option, or a portion thereof, the Option Price of the related Option and (ii) an amount permitted by applicable laws, rules, by-laws or policies of regulatory authorities or stock exchanges. Each Stock Appreciation Right granted independent of an Option shall entitle a Participant upon exercise to an amount equal to (i) the excess of (A) the Fair Market Value on the exercise date of one Share over (B) the exercise price per Share, times (ii) the number of Shares covered by the Stock Appreciation Right. Each Stock Appreciation Right granted in conjunction with an Option, or a portion thereof, shall entitle a Participant to surrender to the Company the unexercised Option, or any portion thereof, and to receive from the Company in exchange therefor an amount equal to (i) the excess of (A) the Fair Market Value on the exercise date of one Share over (B) the Option Price per Share, times (ii) the number of Shares covered by the Option, or portion thereof, which is surrendered. The date a notice of exercise is received by the Company shall be the exercise date. Payment shall be made in Shares or in cash, or partly in Shares and partly in cash (any such Shares valued at such Fair Market Value), all as shall be determined by the Committee. Stock Appreciation Rights may be exercised from time to time upon actual receipt by the Company of


6

written notice of exercise stating the number of Shares with respect to which the Stock Appreciation Right is being exercised. No fractional Shares will be issued in payment for Stock Appreciation Rights, but instead cash will be paid for a fraction or, if the Committee should so determine, the number of Shares will be rounded downward to the next whole Share.

(c) Limitations. The Committee may impose, in its discretion, such conditions upon the exercisability or transferability of Stock Appreciation Rights as it may deem fit.

(d) Limited Stock Appreciation Rights. The Committee may grant LSARs that are exercisable upon the occurrence of specified contingent events. Such LSARs may provide for a different method of determining appreciation, may specify that payment will be made only in cash and may provide that any related Awards are not exercisable while such LSARs are exercisable. Unless the context otherwise requires, whenever the term "Stock Appreciation Right" is used in the Plan, such term shall include LSARs.

8. Other Stock-Based Awards

(a) Generally. The Committee, in its sole discretion, may grant Awards of Shares, Awards of restricted Shares and Awards that are valued in whole or in part by reference to, or are otherwise based on the Fair Market Value of, Shares ("Other Stock-Based Awards"). Such Other Stock-Based Awards shall be in such form, and dependent on such conditions, as the Committee shall determine, including, without limitation, the right to receive one or more Shares (or the equivalent cash value of such Shares) upon the completion of a specified period of service, the occurrence of an event and/or the attainment of performance objectives. Other Stock-Based Awards may be granted alone or in addition to any other Awards granted under the Plan. Subject to the provisions of the Plan, the Committee shall determine to whom and when Other Stock-Based Awards will be made, the number of Shares to be awarded under (or otherwise related to) such Other Stock-Based Awards; whether such Other Stock-Based Awards shall be settled in cash, Shares or a combination of cash and Shares; and all other terms and conditions of such Awards (including, without limitation, the vesting provisions thereof and provisions ensuring that all Shares so awarded and issued shall be fully paid and non-assessable).

(b) Performance-Based Awards. Notwithstanding anything to the contrary herein, certain Other Stock-Based Awards granted under this Section 8 may be granted in a manner which is deductible by the Company under Section 162(m) of the Code (or any successor section thereto) ("Performance-Based Awards"). A Participant's Performance-Based Award shall be determined based on the attainment of written performance goals approved by the Committee for a performance period established by the Committee (i) while the outcome for that performance period is substantially uncertain and (ii) no more than 90 days after the commencement of the performance period to which the performance goal relates or, if less, the number of days which is equal to 25 percent of the relevant performance period. The performance goals, which must be objective, shall be based upon one or more of the following criteria: (i) consolidated earnings before or after taxes (including earnings before interest, taxes, depreciation and amortization); (ii) net income; (iii) operating income; (iv) earnings per Share; (v) book value per Share; (vi) return on shareholders' equity; (vii) expense management; (viii)


7

return on investment; (ix) improvements in capital structure; (x) profitability of an identifiable business unit or product; (xi) maintenance or improvement of profit margins; (xii) stock price; (xiii) market share; (xiv) revenues or sales; (xv) costs; (xvi) cash flow; (xvii) working capital and (xviii) return on assets. The foregoing criteria may relate to the Company, one or more of its Subsidiaries or one or more of its divisions or units, or any combination of the foregoing, and may be applied on an absolute basis and/or be relative to one or more peer group companies or indices, or any combination thereof, all as the Committee shall determine. In addition, to the degree consistent with
Section 162(m) of the Code (or any successor section thereto), the performance goals may be calculated without regard to extraordinary items. The maximum amount of a Performance-Based Award during a calendar year to any Participant shall be $5,000,000. The Committee shall determine whether, with respect to a performance period, the applicable performance goals have been met with respect to a given Participant and, if they have, to so certify and ascertain the amount of the applicable Performance-Based Award. No Performance-Based Awards will be paid for such performance period until such certification is made by the Committee. The amount of the Performance-Based Award actually paid to a given Participant may be less than the amount determined by the applicable performance goal formula, at the discretion of the Committee. The amount of the Performance-Based Award determined by the Committee for a performance period shall be paid to the Participant at such time as determined by the Committee in its sole discretion after the end of such performance period; provided, however, that a Participant may, if and to the extent permitted by the Committee and consistent with the provisions of Section 162(m) of the Code, elect to defer payment of a Performance-Based Award.

9. Adjustments Upon Certain Events

Notwithstanding any other provisions in the Plan to the contrary, the following provisions shall apply to all Awards granted under the Plan:

(a) Generally. In the event of any change in the outstanding Shares after the Effective Date by reason of any Share dividend or split, reorganization, recapitalization, merger, consolidation, spin-off, combination or exchange of Shares or other corporate exchange, any distribution to shareholders of Shares other than regular cash dividends or any other similar event, the Committee in its sole discretion and without liability to any person may make such substitution or adjustment, if any, as it deems to be equitable, as to (i) the number or kind of Shares or other securities issued or reserved for issuance pursuant to the Plan or pursuant to outstanding Awards, (ii) the maximum number of Shares for which Options or Stock Appreciation Rights may be granted during a calendar year to any Participant, (iii) the Option Price and/or (iv) any other affected terms of such Awards; provided, however, that the number of Shares issued or reserved for issuance pursuant to the Plan and the maximum number of Shares for which Options or Stock Appreciation Rights may be granted during a calendar year to any Participant shall automatically be adjusted by multiplying such number of Shares by 3,945 to reflect the conversion of Shares pursuant to the proposed merger of the Company into American Axle & Manufacturing Holdings, Inc.


8

(b) Change in Control. Except as otherwise provided in an Award agreement, in the event of a Change in Control, the Committee in its sole discretion and without liability to any person may take such actions, if any, as it deems necessary or desirable with respect to any Award (including, without limitation, (i) the acceleration of an Award, (ii) the payment of a cash amount in exchange for the cancellation of an Award and/or (iii) the requiring of the issuance of substitute Awards that will substantially preserve the value, rights and benefits of any affected Awards previously granted hereunder) as of the date of the consummation of the Change in Control.

10. No Right to Employment

The granting of an Award under the Plan shall impose no obligation on the Company or any Subsidiary to continue the employment of a Participant and shall not lessen or affect the Company's or Subsidiary's right to terminate the employment of such Participant.

11. Successors and Assigns

The Plan shall be binding on all successors and assigns of the Company and a Participant, including without limitation, the estate of such Participant and the executor, administrator or trustee of such estate, or any receiver or trustee in bankruptcy or representative of the Participant's creditors.

12. Nontransferability of Awards

Unless otherwise determined by the Committee, an Award shall not be transferable or assignable by the Participant otherwise than by will or by the laws of descent and distribution. An Award exercisable after the death of a Participant may be exercised by the legatees, personal representatives or distributees of the Participant.

13. Amendments or Termination

The Board may amend, alter or discontinue the Plan, but no amendment, alteration or discontinuation shall be made which, (a) without the approval of the shareholders of the Company, would (except as is provided in
Section 9 of the Plan), increase the total number of Shares reserved for the purposes of the Plan or change the maximum number of Shares for which Awards may be granted to any Participant or (b) without the consent of a Participant, would impair any of the rights or obligations under any Award theretofore granted to such Participant under the Plan; provided, however, that the Committee may amend the Plan in such manner as it deems necessary to permit the granting of Awards meeting the requirements of the Code or other applicable laws. Notwithstanding anything to the contrary herein, the Board may not amend, alter or discontinue the provisions relating to Section 9(b) of the Plan after the occurrence of a Change in Control.


9

14. International Participants

With respect to Participants who reside or work outside the United States of America and who are not (and who are not expected to be) "covered employees" within the meaning of Section 162(m) of the Code, the Committee may, in its sole discretion, amend the terms of the Plan or Awards with respect to such Participants in order to conform such terms with the requirements of local law.

15. Choice of Law

The Plan shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to the conflicts of laws principles thereof.

16. Effectiveness of the Plan

The Plan shall be effective as of the Effective Date.


SENIOR SECURED
PROMISSORY NOTE

$15,000,000 August 14, 1998 New York, New York

FOR VALUE RECEIVED, Richard E. Dauch (the "Payor") promises to pay to the order of American Axle & Manufacturing of Michigan, Inc., a Michigan corporation (the "Company"), in lawful money of the United States of America and in immediately available funds, the principal amount of Fifteen Million Dollars ($15,000,000) ("Maximum Amount") or such lesser amount as may be outstanding from time to time from the Payor to the Company hereunder (the "Loan") on August 14, 2003 (or on such earlier date on which the then unpaid principal amount of the Loan becomes due and payable pursuant to the terms of this Senior Secured Promissory Note (the "Note")). Payments in respect of this Note shall be made by the Payor to the Company at the Company's office at 1840 Holbrook Avenue, Detroit, MI 48212 or at such other place as the Company may designate in writing from time to time.

The Loan to be repaid by the Payor pursuant hereto shall be made on the date hereof by the Company to the Payor to pay taxes due by the Payor in respect of options issued to the Payor in respect of the capital stock of the Company and, thereafter, on each Interest Payment Date, the Payor may borrow from the Company the interest due on such Interest Payment Date from the Payor to the Company so long as at no time shall the aggregate principal amount due hereunder exceed the Maximum Amount.

The Loan shall bear interest (calculated on the basis of a 360 day year for actual days elapsed) during each Interest Period with respect thereto at a rate per annum equal to the Eurodollar Rate applicable to such Interest Period plus 2.00%; provided that the Payor may request the Company to fix the interest rate paid hereunder by fixing the cost to the Company of the funds borrowed hereunder pursuant to an interest rate hedging agreement on terms and conditions reasonable to the Company and to the Pledgor. Interest shall be payable in arrears on each Interest Payment Date.

For purposes hereof, the following definitions shall apply:

"Business Day": a day other than a Saturday, Sunday or other day on which commercial banks in New York City are authorized or required by law to close; provided that the term "Business Day" shall also exclude any day on which banks are not open for dealings in U.S. dollar deposits in the London interbank market.

"Eurodollar Rate": with respect to each Interest Period, the rate of interest determined on the basis of the rate for deposits in U.S. dollars for a period of six months commencing on the first day of such Interest Period appearing on Page 3750 of the Telerate Service as of 11:00 A.M., London time, two Business Days prior to the beginning of such Interest Period. In the event that such rate does not appear on Page 3750 of the Telerate Service (or otherwise on such service), the "Eurodollar Base Rate" shall be determined by reference to such other


publicly available service for displaying eurodollar rates as may be determined by the Company.

"Interest Payment Date": the last day of each Interest Period.

"Interest Period": initially, the period beginning on the date hereof and ending six months thereafter, and thereafter each period commencing on the last day of the preceding Interest Period and ending six months thereafter; provided that if any Interest Period would otherwise end on a day that is not a Business Day such Interest Period shall be extended to the next succeeding Business Day, unless the result of such extension would be to carry such Interest Period into another calendar month in which event such Interest Period shall end on the immediately preceding Business Day.

If any principal or interest or other amount hereunder is not paid when due (whether as stated, by acceleration or otherwise) the unpaid principal hereof and any such overdue interest or other amount shall bear interest during the period from and including the due date to the date of payment in full thereof at the rate per annum equal to 2.00% above the rate otherwise in effect on such date.

The Payor may at his option prepay the principal due under this Note at any time, in whole or in part, without premium, penalty or breakage costs. The Payor shall prepay the principal due under this Note to the extent of the cash proceeds (net of taxes and reasonable transaction expenses) of the sale, assignment or other disposition of any "Options" or "Shares" (in each case as defined in the Nonqualified Stock Option Agreement made as of October 30, 1997 by and between the Company and the Payor). Any prepayment hereunder shall be applied first to accrued and unpaid interest and then to principal.

This Note is secured by the Pledge Agreement (the "Pledge Agreement"), dated as of the date hereof, and made by the undersigned.

If any of the following events (any such event, an "Event of Default") shall occur and be continuing:

(a) The Payor shall fail to pay any principal of this Note within five days after such principal is due in accordance with the terms hereof, or the Payor shall fail to pay interest on this Note, or any fees or other amounts with respect to this Note, within five days after any such interest, fee or other amount becomes due in accordance with the terms hereof; or

(b) Any representation or warranty made by the Payor in connection with this Note or the Pledge Agreement, or in any report, certificate, financial statement or other instrument furnished by or on behalf of the Payor in connection therewith, shall


prove to have been incorrect in any material respect on or as of the date made or deemed made; or

(c) The Payor shall default in the due observance or performance of any covenants or conditions or agreements contained in this Note or the Pledge Agreement or the Pledge Agreement shall fail to be in full force and effect; or

(d) The Payor voluntarily terminates his employment with the Company or such employment has been terminated for "Cause" (as defined in the Employment Agreement between Payor and the Company dated as of November 6, 1997);

then, and in any such event, the Company may by notice to the Payor, declare the Loan (with accrued interest thereon) and all other amounts owed by the Payor in connection therewith to be due and payable forthwith, whereupon the same shall immediately become due and payable. Except as expressly provided above in this paragraph, presentment, demand, protest and all other notices of any kind are hereby expressly waived.

The Payor and every indorser agrees that if an attorney is used to enforce or collect any principal of, interest on or other amount in respect of this Note a reasonable attorney's fee shall be payable by each of them against whom such principal, interest or other amounts or rights hereunder are enforced or declared. The Company and the Payor and each indorser, in any legal action or proceeding (relating to this Note or any agreement executed in connection herewith) irrevocably and unconditionally waive trial by jury, and the Payor and each indorser waives the right to interpose any set-off or counterclaim of any nature or description.

Time for payment extended by law shall be included in the computation of interest.

All notices under this Note or the Pledge Agreement shall be in writing and sent to each party at their address as they shall notify the other party. All notices will be deemed delivered (i) as of the date of delivery if delivered in person or by courier, or (ii) three (3) days after being deposited in the United States mail, postage paid.

THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE

LAWS OF THE STATE OF NEW YORK.
