(e) At the Closing Time, the U.S. Representatives shall have received from Deloitte & Touche LLP a letter, dated as of the Closing Time, to the effect that they reaffirm the statements made in the letter furnished pursuant to subsection (d) of this Section, except that the specified date referred to shall be a date not more than three business days prior to the Closing Time.

(g) Contemporaneously with the purchase by the U.S. Underwriters of the Initial U.S. Securities under this Agreement, the International Managers shall have purchased the Initial International Securities under the International Purchase Agreement. (h) At the Closing Time, and at each Date of Delivery, if any, 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. -35- 36 (i) 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 hereunder shall be true and correct as of, and as if made on, each Date of Delivery, and at the relevant Date of Delivery, the U.S. Representatives shall have received: (1) A certificate, dated such Date of Delivery, of the President or a Vice-President of the Company and the Chief Financial Officer or Chief Accounting Officer of the Company confirming that the certificate delivered at the Closing Time pursuant to Section 5(e) hereof is true and correct as of such Date of Delivery.

Schiffer, Esq., Senior Vice President, General Counsel and Secretary for the Company, in form and substance satisfactory to counsel for the U.S. Underwriters, dated such Date of Delivery, relating to the U.S. Option Securities to be purchased on such Date of Delivery and otherwise to the same effect as the opinion required by Section 5(b)(1) hereof.

If any condition specified in this 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. -36- 37 Options Securities on a Date of Delivery which is after the Closing Time, the obligations of the several U.S. Underwriters to purchase the relevant Option Securities, may be terminated by the U.S. Representatives by notice to the Company at any time at or prior to the 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) 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 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 contained 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 -37- 38 (iii) against any and all expense whatsoever, as incurred (including, the fees, expenses 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 this foregoing 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 Merrill Lynch 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); provided, further, that such indemnity with respect to the preliminary prospectus shall not inure to the benefit of the U.S. Underwriters (or any person controlling such U.S. Underwriters) from whom the person asserting any such loss, liability, claim, damage or expense purchased any of the Securities which are the subject thereof if such person did not receive a copy of the U.S. Prospectus (or the U.S. Prospectus as amended or supplemented) (in each case exclusive of the documents from which information is incorporated by reference) at or prior to the written confirmation of the sale of such U.S. Securities to such person in any case where the Company complied with its obligations under Sections 3(c) and 3(g) hereof and any such untrue statement or omission or alleged untrue statement or omission of a material fact contained in such preliminary prospectus (or any amendment or supplement thereto) was corrected in the U.S. Prospectus (or the U.S. Prospectus as amended or supplemented). (b) 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, -38- 39 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 Merrill Lynch 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) 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 -39- 40 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) If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 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 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. 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 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 -40- 41 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 such 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 such U.S. Securities as set forth on such cover. 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 the untrue or alleged untrue statement of a material fact or the 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 -41- 42 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 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 to this Agreement, and not joint. SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement and the U.S. Pricing Agreement, or contained 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 and payment for the Securities to the U.S. Underwriters. SECTION 9. Termination of Agreement. (a) The U.S. Representatives may terminate this Agreement, by notice to the Company at any time at or prior to the Closing Time, if (i) there has been, since the date of this Agreement or since the respective dates as of which information is given in the U.S. Prospectus, any material adverse change or any -42- 43 development which could reasonably be expected to result in a prospective material adverse change, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) there has occurred any material adverse change in the financial markets in the United States or any outbreak of hostilities or escalation of hostilities or other calamity or crisis, or any change or development involving a prospective change in national or international political, financial or economic conditions 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 the Common Stock or any other security of the Company has been suspended or limited by the Commission, National Association of Securities Dealers, Inc. or the New York Stock Exchange, or if trading generally on either the American Stock Exchange, the New York Stock Exchange or in the over-the-counter market has been suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices for securities have been required, by either of said exchanges or by such system or by order of the Commission, NASD or any other governmental authority, or (iv) if a banking moratorium has been declared by either Federal, New York or Michigan authorities. (b) If this Agreement and the U.S. Pricing Agreement are terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 4, 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 the Closing Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Agreement and the U.S. Pricing 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 -43- 44 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 obligations of the U.S. Underwriters to purchase and of the Company to sell the Option Securities to be purchase 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 10 shall relieve any defaulting U.S. Underwriter from liability in respect of its default. In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the U.S. Underwriters to purchase and the Company to sell the relevant U.S. Option Securities, as the case may be, either the U.S. Representatives or 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 the Prospectuses or in any other documents or arrangements. As used herein, the term "U.S. Underwriter" includes any person substituted for an U.S. Underwriter under this Section 10. SECTION 11. 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 -44- 45 directed to the U.S. Representatives at North Tower, World Financial Center, New York, New York 10281-1202, attention of Anthony V. Leness, Managing Director, with a copy to LeBoeuf, Lamb, Greene & MacRae, L.L.P., 125 West 55th Street, New York, New York 10019-5389, attention of William S.

Schiffer, Esq., Senior Vice President, General Counsel and Secretary. SECTION 12. Parties. This Agreement and the U.S. Pricing Agreement shall each inure to the benefit of and be binding upon the Company and the U.S. Underwriters and their respective successors. Nothing expressed or mentioned in this Agreement or the U.S. Pricing Agreement is intended or shall be construed to give any person, firm or corporation, other than the U.S. Underwriters and 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 the U.S. Pricing Agreement or any provision herein or therein contained. This Agreement and the U.S. Pricing Agreement and all conditions and provisions hereof and thereof are intended to be for the sole and exclusive benefit of the parties hereto and thereto and their respective successors and legal representatives, 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 13. GOVERNING LAW AND TIME. THIS AGREEMENT AND THE U.S. PRICING AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SAID STATE.
