The Notes are to be issued under an indenture (the “Indenture”) dated as of August 1, 1990, between the Company and The Bank of New York Mellon Trust Company, N.A. (formerly known as The Bank of New York Trust Company, N.A.), successor to JPMorgan Chase Bank, N.A., (formerly The Chase Manhattan Bank), as trustee (the “Trustee”), as supplemented and amended by the First Supplemental Indenture dated as of June 15, 1991, the Second Supplemental Indenture dated as of May 6, 1997, the Third Supplemental Indenture dated as of April 22, 1998, the Fourth Supplemental Indenture dated as of October 30, 2001, the Fifth Supplemental Indenture dated as of October 27, 2003, the Sixth Supplemental Indenture dated as of September 23, 2004 and the Seventh Supplemental Indenture dated as of April 25, 2007.

In connection with the sale of the Notes, the Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3ASR (Registration No. 333-140732) for the registration of debt securities, including the Notes, trust preferred securities (and related guarantee and agreement as to expenses and liabilities), common stock, preferred stock, depositary shares and securities warrants, under the Securities Act of 1933, as amended (the “Securities Act”). On December 10, 2007, the Company and CSX Transportation, Inc., a Virginia corporation, filed with the Commission Post-Effective Amendment No. 1 to the Registration Statement, including the related Base Prospectus, which Post-Effective Amendment No. 1 became effective upon filing under Rule 462(e) and 462(f) under the Securities Act. Such amended Registration Statement covers the registration of the Notes under the Securities Act. Any reference herein to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Final Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 which were filed under the Exchange Act on or before the Effective Date of the Registration Statement or the issue date of the Base Prospectus, any Preliminary Prospectus or the Final Prospectus, as the case may be; and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Final Prospectus shall be deemed to refer to and include the filing of any document under the Exchange Act (as defined in Section 1(b) hereof) after the Effective Date of the Registration Statement or the issue date of the Base Prospectus, any Preliminary Prospectus or the Final Prospectus, as the case may be, deemed to be incorporated therein by reference. The Company hereby confirms that it has authorized the use of the Base Prospectus, any Preliminary Prospectus and the Final Prospectus, and any amendment or supplement thereto, in connection with the offer and sale of the Notes by the Underwriters. Certain terms used herein are defined in Section 18 hereof.

1. Representations and Warranties. The Company represents and warrants to, and agrees with, each Underwriter as set forth below in this Section 1.

Such Registration Statement, including any amendments thereto filed prior to the Applicable Time, has become effective. The Company may have filed with the Commission, as part of an amendment to the Registration Statement or pursuant to Rule 424(b), one or more preliminary prospectus supplements relating to the Notes, each of which has previously been electronically furnished to you. The Company will file with the Commission a final prospectus supplement relating to the Notes in accordance with Rule 424(b). As filed, such final prospectus supplement shall contain all information required by the Securities Act and the rules thereunder, and, except to the extent the Representatives shall agree in writing to a modification, shall be in all substantive respects in the form furnished to you prior to the Applicable Time or, to the extent not completed at the Applicable Time, shall contain only such specific additional information and other changes (beyond that contained in the Base Prospectus and any Preliminary Prospectus) as the Company has advised you, prior to the Applicable Time, will be included or made therein. The Registration Statement, at the Applicable Time, meets the requirements set forth in Rule 415(a)(1)(x).

(b) On the Effective Date, the Registration Statement did, and the Final Prospectus (and any supplement thereto), as of its date and on the Closing Date (as defined in Section 3 hereof), will, comply in all material respects with the requirements of the Securities Act and the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the Trust Indenture Act of 1939, as amended (the “TIA”), and the rules and regulations of the Commission promulgated thereunder.

(i) Assuming that the Indenture has been duly authorized, executed and delivered by the Company, the Indenture has been duly qualified under the Trust Indenture Act of 1939 and constitutes a legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms (subject to applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and other similar laws affecting creditors’ rights generally from time to time in effect and to general principles of equity, including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing, regardless of whether considered in a proceeding in equity or at law); and assuming that the Notes have been duly authorized, when the Notes are executed and authenticated in accordance with the provisions of the Indenture and delivered to and paid for by the Underwriters pursuant to this Agreement, the Notes conform in all material respects to the description thereof contained in the Disclosure Package, the Base Prospectus and the Final Prospectus and will constitute legal, valid and binding obligations of the Company entitled to the benefits of the Indenture and enforceable against the Company in accordance with their terms (subject to applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and other similar laws affecting creditors’ rights generally from time to time in effect and to general principles of equity, including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing, regardless of whether considered in a proceeding in equity or at law);

(ii) This Agreement has been duly authorized, executed and delivered by the Company;

(iii) The Registration Statement initially became effective under the Securities Act on February 15, 2007; the Preliminary Prospectus was filed with the Commission pursuant to Rule 424(b)(3), the Final Prospectus was filed with the Commission pursuant to Rule 424(b)(5), and a term sheet was filed with the Commission pursuant to Rule 433. Thereupon, assuming prior payment by the Company of the pay-as-you-go registration fee for the offering of Notes, upon the filing of the Base Prospectus and the Final Prospectus with the Commission, the offering of the Notes as contemplated by the Base Prospectus and the Final Prospectus became registered under the Securities Act; to such counsel’s knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are pending or contemplated under the Securities Act;

(iv) The Company is not an “investment company” as such term is defined in the Investment Company Act of 1940, as amended;

(v) The statements made in the Disclosure Package, the Base Prospectus and the Final Prospectus under the captions “Description of Debt Securities” and “Description of Notes,” insofar as they purport to constitute summaries of the terms of the Notes and the Indenture, and under the caption “Certain Tax Considerations,” insofar as they purport to describe the material tax consequences of an investment in the Notes, fairly summarize the matters therein described;

In addition, subject to such counsel’s customary qualifications about the scope of its obligations in connection with its participation in the preparation of documents, such counsel shall state that they have participated in conferences with officers and other representatives of the Company, representatives of Ernst & Young LLP, independent auditors for the Company, the Representatives and Counsel for the Underwriters at which the contents of the Registration Statement, Disclosure Package and the Final Prospectus and any amendment thereof or supplement thereto and related matters were discussed, and, although such counsel have not undertaken to investigate or verify independently, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained in the Registration Statement, Disclosure Package and the Final Prospectus or any amendment thereof or supplement thereto (other than to the extent addressed in paragraph (c)(i) and paragraph (c)(v) in this Section 5), and did not participate in the preparation of the documents incorporated by reference in the Registration Statement or any Preliminary Prospectus and the Final Prospectus, (A) the Registration Statement, at the time it initially became effective, appeared on its face to be appropriately responsive in all material respects to the requirements of the Securities Act and the rules and regulations promulgated thereunder (except that such counsel need not express any view as to the financial statements and other information of a statistical, accounting or financial nature included in the Registration Statement or the Statement of Eligibility (Form T-1)); and (B) no facts have come to the attention of such counsel that would lead such counsel to believe (i) that the Registration Statement (other than the historical, pro forma, projected or other financial statements, information and data and statistical information and data included or incorporated by reference therein or omitted therefrom, and Form T-1, in each case as to which no opinion need be given), at the Applicable Time, contained any untrue statement of a material fact, or omitted to state a material fact necessary in order to make the statements therein not misleading or (ii) that (x) the Disclosure Package, as of the Applicable Time, or (y) the Final Prospectus as amended or supplemented as of its date or as of the Closing Date (in each case, other than the historical, pro forma, projected or other financial statements, information and data and statistical information and data included or incorporated by reference therein or omitted therefrom, in each case as to which no opinion need be given) includes or will include any untrue statement of a material fact or omits 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.

In rendering such opinion, Cravath, Swaine & Xxxxx LLP may rely (A) as to matters governed by Virginia law upon the opinion of the Senior Vice President — Law and Public Affairs and Corporate Secretary, General Counsel or Assistant General Counsel of the Company and (B) as to matters of fact, to the extent they deem proper, on certificates of responsible officers of the Company and public officials. Except as otherwise set forth herein, all references in this Section 5(c) to the Final Prospectus shall be deemed to include any amendment or supplement thereto at the Closing Date.

(d) The Representatives shall have received from Counsel for the Underwriters such opinion or opinions, dated the Closing Date, with respect to the issuance and sale of the Notes, the Registration Statement, the Disclosure Package and the Final Prospectus (as amended or supplemented at the Closing Date) and other related matters as they may require, and the Company shall have furnished to such counsel such documents as they may reasonably request for the purpose of enabling them to pass upon such matters. In rendering such opinion, Counsel for the Underwriters may rely as to all matters governed by Virginia law on the opinion of the Senior Vice President — Law and Public Affairs and Corporate Secretary, General Counsel or Assistant General Counsel of the Company, referred to above.

(e) The Company shall have furnished to the Representatives a certificate of the Company, signed by the Chairman of the Board, President and Chief Executive Officer, any Vice President or the Assistant Vice President — Capital Markets and another person who is the principal financial or accounting officer of the Company, or, in their absence, other proper officers of the Company satisfactory to the Representatives, dated the Closing Date, to the effect that the signers of such certificate have examined the Registration Statement, the Disclosure Package, the Final Prospectus, any amendment or supplement thereto and this Agreement and that, to the best of their knowledge after reasonable investigation:

(i) the representations and warranties of the Company in this Agreement are true and correct in all material respects on and as of the Closing Date with the same effect as if made on and as of such date, and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date; and

(ii) since the date of the most recent financial statements incorporated by reference in the Disclosure Package and the Final Prospectus, there has been no material adverse change in the condition (financial or other), earnings, business or properties of the Company and its subsidiaries considered as one enterprise, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated by the Disclosure Package and the Final Prospectus (exclusive of any amendment or supplement thereto after the date hereof) or as described in such certificate.

(f) At the Applicable Time and at the Closing Date, Ernst & Young LLP shall have furnished to the Representatives letters, dated respectively as of the Applicable Time and as of the Closing Date, in form and substance satisfactory to the Representatives, confirming that they are independent accountants within the meaning of the Securities Act and the Exchange Act and the respective applicable rules and regulations adopted by the Commission thereunder and containing statements and information of the type ordinarily included in accountants’ “comfort letters” to underwriters with respect to the financial statements and certain financial information contained in the Registration Statement, Preliminary Prospectus and Final Prospectus.

(g) Subsequent to the Applicable Time or, if earlier, the dates as of which information is given in the Registration Statement (exclusive of any amendment thereof) and the Final Prospectus (exclusive of any supplement thereto), there shall not have been (i) any change or decrease specified in the letters referred to in paragraph (f) of this Section 5 or (ii) any change, or any development involving a prospective change, in or affecting the business or properties of the Company and its subsidiaries, the effect of which, in any case referred to in clause (i) or (ii) above, is, in the reasonable judgment of the Representatives, so material and adverse as to make it impractical or inadvisable to market the Notes as contemplated by the Disclosure Package and the Final Prospectus (exclusive of any amendment or supplement thereof or thereto after the date hereof).

(h) Subsequent to the Applicable Time, there shall not have been any decrease in the rating of any of the Company’s debt securities by Xxxxx’x Investors Service, Inc. or Standard & Poor’s Ratings Group or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the direction of the possible change.

(i) Prior to the Closing Date, the Company shall furnish to the Representatives such conformed copies of such opinions, certificates, letters and documents as the Representatives may reasonably request.

If any of the conditions specified in this Section 5 shall not have been fulfilled in all material respects when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be in all material respects reasonably satisfactory in form and substance to the Representatives and Counsel for the Underwriters, this Agreement and all obligations of the Underwriters hereunder with respect to the Notes may be canceled at, or at any time prior to, the Closing Date by the Representatives. Notice of such cancellation shall be given to the Company in writing or by telephone or telefax confirmed in writing.

The documents required to be delivered by this Section 5 will be delivered at the office of Counsel for the Underwriters, at 000 Xxxxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, on the Closing Date.

6. Reimbursement of Expenses. If the sale of the Notes provided for herein is not consummated because of cancellation by the Representatives pursuant to Section 5 hereof, because of any termination pursuant to Section 9 hereof or because of any refusal, inability or failure on the part of the Company to perform any material agreement herein or comply with any material provision hereof other than by reason of a default by any of the Underwriters in payment for the Notes on the Closing Date, the Company will reimburse the Underwriters severally upon demand for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of Counsel for the Underwriters) that shall have been incurred by them in connection with the proposed purchase and sale of the Notes.

7. Indemnification and Contribution. (a) The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees, affiliates and agents of each Underwriter and each person who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or in the Base Prospectus, any Preliminary Prospectus or any other preliminary prospectus supplement relating to the Notes, the Final Prospectus, any Issuer Free Writing Prospectus or the information contained in the final term sheet required to be prepared and filed pursuant to Section 4(I)(c) hereto, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriters through the Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability the Company may otherwise have.

(b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, its directors, its officers, and each person who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to information relating to such Underwriter furnished in writing to the Company by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. The Company and each Underwriter acknowledge that the statements set forth in the fourth paragraph, sixth paragraph, twelfth paragraph, thirteenth paragraph and fourteenth paragraph of text under the heading “Underwriting” in the Preliminary Prospectus and the fourth paragraph, sixth paragraph, thirteenth paragraph, fourteenth paragraph and fifteenth paragraph of text under the heading “Underwriting” in the Final Prospectus constitute the only information furnished in writing by or on behalf of the Underwriters for inclusion in the Preliminary Prospectus or the Final Prospectus (or in any amendment or supplement thereto). The Company and Mitsubishi UFJ Securities International plc acknowledge that the statements set forth in the seventh paragraph of text under the heading “Underwriting” in the Final Prospectus constitute information furnished in writing by or on behalf of Mitsubishi UFJ Securities International plc for inclusion in the Preliminary Prospectus or the Final Prospectus (or in any amendment or supplement thereto).

(c) Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel); however, the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel only if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded upon advice of counsel that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding 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. An indemnifying party shall not be liable under this Section 7 to any indemnified party regarding any settlement or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise, or consent is consented to by such indemnifying party, which consent shall not be unreasonably withheld.

(d) If the indemnity provided in paragraph (a) or (b) of this Section 7 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Underwriters agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively “Losses”) to which the Company and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company and by the Underwriters from the offering of the Notes. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Underwriters shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and of the Underwriters in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses), and benefits received by the Underwriters shall be deemed to be equal to the total purchase discounts and commissions received by the Underwriters from the Company in connection with the purchase of the Notes hereunder, in each case as set forth on the cover page of the Final Prospectus. Relative fault shall be determined by reference to whether any alleged untrue statement or omission relates to information provided by the Company or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute as provided in this Section 7(d) are several in proportion to their respective purchase obligations and not joint. For purposes of this Section 7, each person who controls an Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each officer and director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d). Notwithstanding the provisions of this paragraph (d), in no case shall any Underwriter (except as may be provided in any agreement among the Underwriters relating to the offering of the Notes) be responsible for any amount in excess of the purchase discount or commission applicable to the Notes purchased by such Underwriter hereunder, in each case as set forth on the cover page of the Final Prospectus.

8. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Notes agreed to be purchased by such Underwriter hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Notes set forth opposite their names in Schedule II hereto bears to the aggregate principal amount of Notes set forth opposite the names of all the remaining Underwriters) the Notes which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that if the aggregate principal amount of Notes which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Notes set forth in Schedule II hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Notes, and if such non-defaulting Underwriters do not purchase all the Notes within 36 hours of such default, this Agreement will terminate without liability to any non-defaulting Underwriter or the Company except as otherwise provided in Section 10. In the event of a default by any Underwriter as set forth in this Section 8, the Closing Date shall be postponed for such period, not exceeding seven days, as the Representatives shall determine in order that the required changes in the Final Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company or to any non-defaulting Underwriter for damages occasioned by its default hereunder.

9. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the applicable Notes, if prior to such time (i) there shall have occurred any change, or any development involving a prospective change, in or affecting particularly the business or properties of the Company or its subsidiaries which, in the judgment of the Representatives, materially impairs the investment quality of the Notes, (ii) any downgrading in the rating of any debt securities of the Company by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g) under the Securities Act), or any public announcement that any such organization has under surveillance or review its rating of any debt securities of the Company (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating), (iii) trading in any of the Company’s securities shall have been suspended by the Commission or the New York Stock Exchange or trading in securities generally on the New York Stock Exchange shall have been suspended or materially limited or minimum prices shall have been established on such exchange, (iv) a banking moratorium shall have been declared either by federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war or other calamity or crisis the effect of which on financial markets is such as to make it, in the reasonable judgment of the Representatives, impracticable or inadvisable to proceed with the offering or delivery of the Notes as contemplated by any Preliminary Prospectus or the Final Prospectus (exclusive of any amendment or supplement thereof or thereto after the date hereof).

10. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Underwriters or the Company or any of the officers, directors or controlling persons referred to in Section 7 hereof, and will survive delivery of and payment for the Notes. The provisions of Sections 6 and 7 hereof shall survive the termination or cancellation of this Agreement.

11. Fees, Expenses. The Company covenants and agrees with the Representatives that the Company will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Company’s counsel and accountants in connection with the issue of the Notes and all other expenses in connection with the preparation and printing of the Final Prospectus and any amendments and supplements thereto and the mailing and delivering of copies thereof to the Underwriters; (ii) the cost of printing or other production of all documents relating to the offering, purchase, sale and delivery of the Notes as provided in Section 4(I)(a); (iii) any fees charged by securities rating services for rating the Notes; (iv) the cost of preparing the Notes; (v) the fees and expenses of the Trustee and any agent of the Trustee and the fees and disbursements of counsel for the Trustee in connection with the Indenture and the Notes; (vi) any fees charged by DTC; (vii) all expenses in connection with the qualification of the Notes for offering and sale under state and Canadian securities laws, including the fees and disbursements of Counsel for the Underwriters in connection with such qualification and in connection with Blue Sky and Legal Investment Survey and Canadian offering documents; and (viii) all other costs and expenses incident to the performance of its obligations hereunder which are not otherwise specifically provided for in this Section 11. It is understood, however, that except as provided in Sections 6 and 11 hereof, the Underwriters will pay all of their own costs and expenses, including the fees, disbursements and expenses of their counsel and any marketing expenses connected with any offers they may make.

12. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Representatives, will be mailed, delivered or telefaxed and confirmed to them, care of (i) Credit Suisse Securities (USA) LLC, Eleven Madison Avenue, New York, N.Y. 10010-3629, attention: Xxxx Xxxxxxxxx, phone: (000) 000-0000, facsimile: (000) 000-0000; and (ii) X.X.

13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 7 hereof, and no other person will have any right or obligation hereunder.

14. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York.

15. No Fiduciary Duty. The Company hereby acknowledges that (a) the purchase and sale of the Notes pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the Underwriters and any affiliate through which it may be acting, on the other, (b) the Underwriters are acting as principal and not as an agent or fiduciary of the Company and (c) the Company’s engagement of the Underwriters in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Company agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether any of the Underwriters has advised or is currently advising the Company on related or other matters). The Company agrees that it will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.
