A final prospectus supplement relating to the Securities, the terms of the offering thereof and the other matters set forth therein will be prepared and filed pursuant to Rule 424(b) of the 1933 Act Rules and Regulations. Such final prospectus supplement, in the form first filed after the date hereof pursuant to Rule 424(b), is herein referred to as the "Prospectus Supplement." The registration statement, as amended at the date hereof, including the exhibits thereto, is herein called the "Registration Statement," and the Basic Prospectus included therein, as supplemented by the Prospectus Supplement, is herein called the "Prospectus;" provided, however, that if such Prospectus is amended or supplemented on or after the date hereof but prior to the date on which the Prospectus Supplement is first filed pursuant to Rule 424(b), the term "Prospectus" shall refer to such Prospectus as so amended or supplemented and as supplemented by the Prospectus Supplement; and provided, further, that all references to the "Registration Statement" and the "Prospectus" shall be deemed to include all documents incorporated therein by reference pursuant to the Securities Exchange Act of 1934, as amended (the "1934 Act"). If an abbreviated registration statement is prepared and filed with the SEC in accordance with Rule 462(b) under the 1933 Act (an "Abbreviated Registration Statement"), the term "Registration Statement" as used in this Agreement includes the Abbreviated Registration Statement. For purposes of this Agreement, the words "amend," "amendment," "amended," "supplement" or "supplemented" with respect to the Registration Statement or the Prospectus shall mean amendments or supplements to the Registration Statement or the Prospectus, as the case may be, as well as documents filed after the date of this Agreement and prior to the completion of the distribution of the Securities and incorporated by reference therein as described above.

At the respective times the Registration Statement and 3 4 any post-effective amendments thereto became or become effective, the Registration Statement and any amendments or supplements thereto complied or will comply in all material respects with the requirements of, the 1933 Act and the 1933 Act Rules and Regulations and did not and will not contain, as the case may be, any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading; and neither the Preliminary Prospectus Supplement, the Prospectus nor any supplement thereto contained or will contain, as the case may be, any untrue statement of a material fact or omitted or will omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Company makes no representation or warranty as to (i) information contained in or omitted from the Registration Statement, the Preliminary Prospectus Supplement or the Prospectus, or any such amendment or supplement, in reliance upon, and in conformity with, written information furnished to the Company relating to the Underwriters by or on behalf of the Underwriters expressly for use in the preparation thereof (as provided in Section 12 hereof) and (ii) the Statement of Eligibility and Qualification (the "Form T-1") under the Trust Indenture Act of 1939, as amended (the "1939 Act"), which is included as an exhibit to the Registration Statement.

The documents incorporated by reference in the Prospectus pursuant to Item 12 of Form S-3 under the 1933 Act, at the time they were filed with the SEC, complied in all material respects with the requirements of the 1934 Act and the rules and regulations adopted by the SEC thereunder (the "1934 Act Rules and Regulations"). Any future documents incorporated by reference so filed, when they are filed, will comply in all material respects with the requirements of the 1934 Act and the 1934 Act Rules and Regulations; at the time of filing, no such incorporated document contained or will contain any 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; and, when read together and with the other information in the Prospectus, at the time the Registration Statement became effective and at the Closing Date, each such incorporated document did not or will not, as the case may be, 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.

(b) No Underwriter shall have advised the Company on or prior to the Closing Date (and, if applicable, the Option Closing Date) that the Registration Statement or Prospectus or any amendment or supplement thereto contains an untrue statement of fact which, in the opinion of counsel to the Underwriters, is material, or omits to state a fact which, in the opinion of such counsel, is material and is required to be stated therein or is necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. (c) On the Closing Date (and, if applicable, the Option Closing Date), the Underwriters shall have received the opinion of Haynes and Boone, LLP, counsel for the Company, addressed to the Underwriters and dated the Closing Date, to the effect that: (i) The Registration Statement and all post-effective amendments thereto and the Abbreviated Registration Statement, if any, have become effective under the 1933 Act; any required filing of the Prospectus or any supplement thereto pursuant to Rule 424(b) or otherwise has been made in the manner and within the time period required thereby; and, to the knowledge of such counsel after due inquiry, no stop or other 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 1933 Act or under the securities laws of any jurisdiction. (ii) The Registration Statement and the Prospectus, and each amendment or supplement thereto (including any document incorporated by reference into the Prospectus), as of their respective effective or issue date, comply as to form and appear on their face to be appropriately responsive in all material respects to the requirements of Form S-3 under the 1933 Act and the applicable 1933 Act Rules and Regulations (except that such counsel need express no opinion as to the Form T-1, the financial statements, the schedules, reserve information and other financial and statistical data included in the Registration Statement or in the Prospectus or in any document incorporated by reference therein) the conditions for use of Form S-3 have been satisfied; and, as of the date they were filed with the SEC, the documents incorporated by reference in the Registration Statement appear on their face to comply as to form and be appropriately responsive in all material respects with the requirements of the 1934 Act and the applicable 1934 Act Rules and Regulations (except that 15 16 such counsel need express no opinion as to the Form T-1, financial statements, the schedules, reserve information and other financial and statistical data included in such documents). (iii) To the extent summarized therein, all contracts and agreements summarized in the Registration Statement and the Prospectus are fairly summarized therein, conform in all material respects to the descriptions thereof contained therein, and, to the extent such contracts or agreements or any other material agreements are required under the 1933 Act, or the 1933 Act Rules and Regulations, to be filed, as exhibits to the Registration Statement, they are so filed; and such counsel does not know of any contracts or other documents required to be summarized or disclosed in the Prospectus or to be so filed as exhibits to the Registration Statement that have not been so summarized, disclosed or so filed. (iv) This Agreement has been duly authorized, executed and delivered by the Company. (v) The Company and its subsidiaries have been duly incorporated and are validly existing as corporations in good standing under the laws of the states or other jurisdictions in which they are incorporated. CN is the only partnership of which the Company or any of its subsidiaries is a general partner or owns fifty percent or more of the partnership interests. CN is a general partnership duly organized under the laws of the State of Texas, and the Company owns all of the partnership interests in CN. Each of the Company, its subsidiaries and CN has full corporate power and authority to own, lease and operate their properties and conduct their businesses as described in the Prospectus and, with respect to the Company, to execute and deliver, and perform the Company's obligations under, this Agreement and the Indenture; each of the Company, its subsidiaries and CN is duly qualified to do business as a foreign corporation or partnership in good standing in each state or other jurisdiction in which their ownership or leasing of property or conduct of business legally requires such qualification, except where the failure to be so qualified, individually or in the aggregate, would not have a Material Adverse Effect. (vi) The Company is the sole record owner, directly or indirectly, of all of the outstanding capital stock of each of its subsidiaries. (vii) The issuance and sale of the Securities and the execution, delivery and performance by the Company of this Agreement and the Indenture, and the consummation of the transactions contemplated herein and therein, will not conflict with or constitute a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any properties or assets of the Company, any of its subsidiaries or CN under any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument known to such counsel after due inquiry to which the Company, any of its subsidiaries or CN is a party or by which the Company, any of its subsidiaries or CN is bound or to which any of the properties or assets of the Company, any of its subsidiaries or CN is subject, except to such extent as, individually or in the aggregate, would not have a Material Adverse Effect, nor will such action result in any violation of the provisions of the certificate of incorporation or bylaws or other organizational documents of the Company, any of its subsidiaries or CN or any 16 17 statute, rule, regulation or other law, or any order or judgment known to such counsel after due inquiry, of any court or governmental agency or body having jurisdiction over the Company, any of its subsidiaries or CN or any of their properties. (viii) No consent, approval, authorization, order, registration or qualification of or with any court or governmental agency or body is required in connection with the execution, delivery and performance of this Agreement, and the issuance and sale of the Securities or the consummation of the transactions contemplated hereby, except such as may be required under the 1933 Act, the 1933 Act Rules and Regulations or the 1939 Act and have been obtained, or as may be required by the NASD or under state securities or blue sky laws in connection with the purchase and distribution of the Securities by the Underwriters. (ix) To the knowledge of such counsel after due inquiry and other than as set forth in the Prospectus, there are no legal or governmental proceedings pending to which the Company, any of its subsidiaries or CN is a party or of which any property of the Company, any of its subsidiaries or CN is the subject that, if determined adversely to the Company, any of its subsidiaries or CN, would individually or in the aggregate have a material adverse effect on the current or future consolidated financial position, stockholders' equity or results of operations of the Company, its subsidiaries and CN taken as a whole; and, to the knowledge of such counsel after due inquiry, no such proceedings are threatened or contemplated by governmental authorities or threatened by others. (x) The Company has duly and validly authorized capital stock as set forth under the caption "Capitalization" in the Prospectus; all outstanding shares of Common Stock and Series A Preferred Stock of the Company conform as to legal matters to the description thereof in the Prospectus and have been duly authorized and validly issued, and are fully paid and non-assessable. The Securities have been duly authorized and, when issued, authenticated by the Trustee and delivered and paid for in accordance with this Agreement and the Indenture, will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms and entitled to the benefits of the Indenture, except as may be limited by the Exceptions. The Securities are duly authorized for trading, subject to official notice of issuance, on the New York Stock Exchange. The form of global certificate representing the Securities filed as an exhibit to the Registration Statement is in valid and sufficient form. (xi) The Indenture has been duly authorized, executed and delivered by the Company and constitutes a valid and legally binding instrument of the Company enforceable against the Company in accordance with its terms, except as may be limited by the Exceptions; the Indenture and the Securities conform to the descriptions thereof in the Prospectus; and the Indenture has been duly qualified under the 1939 Act. (xii) The statements made in the Prospectus under the captions "Risk Factors," "Business and Properties," "Description of the Notes," "Description of Bank Credit Facility and Other Indebtedness," "Description of Capital Stock" and Item 15 of Part II of the Registration Statement, and in the Company's Annual Report on Form 10-K for the year ended December 31, 1999 under Item 11, "Executive Compensation" and Item 13, "Certain 17 18 Relationships and Related Transactions," to the extent that they constitute summaries of documents referred to therein or matters of law or legal conclusions, have been reviewed by such counsel and are accurate summaries and fairly present the information disclosed therein. (xiii) The Company is not and, after giving effect to the offering and sale of the Securities, will not be a "holding company," or a "subsidiary company" of a "holding company," or an "affiliate" of a "holding company" or of a "subsidiary company," as such terms are defined in the 1935 Act. (xiv) The Company is not and, after giving effect to the offering and sale of the Securities, will not be an "investment company" or an entity "controlled" by an "investment company," as such terms are defined in the 1940 Act. (xv) To the knowledge of such counsel after due inquiry and except as disclosed in the Prospectus, no holder of any security of the Company has any right to require registration of shares of Common Stock or any other security of the Company because of the filing of the Registration Statement or the consummation of the transactions contemplated hereby that have not been waived and, except as disclosed in the Prospectus or incorporated by reference therein, no person has the right to require registration under the 1933 Act of any shares of Common Stock or other securities of the Company. Such counsel shall confirm that during the preparation of the Registration Statement and Prospectus, such counsel participated in conferences with the Underwriters and their counsel and with officers and representatives of the Company and its independent accountants, at which conferences the contents of the Registration Statement and the Prospectus (including all documents filed under the 1934 Act and deemed incorporated by reference therein) were discussed, reviewed and revised. On the basis of the information which was developed in the course thereof, considered in light of such counsel's understanding of applicable law and the experience gained by such counsel through their practice thereunder, without such counsel assuming responsibility for the accuracy and completeness of such statements except to the extent expressly provided above, such counsel shall confirm that nothing came to their attention that would lead them to believe that either the Registration Statement (including any document filed under the 1934 Act and deemed incorporated by reference therein), as of its effective date and as of the date of filing of the Annual Report on Form 10-K, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or the Prospectus or any amendment or supplement thereto (including any document filed under the 1934 Act and deemed incorporated by reference therein) as of its respective issue date and as of the Closing Date, contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. Such counsel may state that they are not giving advice as to the Form T-1, the financial statements, the schedules, reserve information and other financial and statistical data included in the Registration Statement or in the Prospectus or in any document incorporated by reference therein. In rendering the foregoing opinion, such counsel may rely, (1) as to matters involving laws of any jurisdiction other than Texas, Delaware, New York or the United States, upon opinions 18 19 addressed to the Underwriters or other counsel satisfactory to them and Vinson & Elkins L.L.P., and (2) as to all matters of fact, upon certificates and written statements of the executive officers of, and accountants for, the Company, provided, in either case, that such counsel shall state in their opinion that they and the Underwriters are justified in relying thereon. (d) The Underwriters shall have received on the Closing Date (and, if applicable, the Option Closing Date) from Vinson & Elkins L.L.P., counsel to the Underwriters, an opinion, dated the Closing Date, with respect to such matters as the Underwriters may reasonably require; and the Company shall have furnished to such counsel such documents as they reasonably request for the purposes of enabling them to review or pass on the matters referred to in this Section 6 and in order to evidence the accuracy, completeness and satisfaction of the representations, warranties and conditions herein contained. (e) On the date of this Agreement and on the Closing Date (and, if applicable, the Option Closing Date), the Underwriters shall have received from Arthur Andersen LLP, a letter or letters, dated the date of this Agreement and the Closing Date (and, if applicable, the Option Closing Date), respectively, in form and substance satisfactory to the Underwriters, confirming that they are independent public accountants with respect to the Company within the meaning of the 1933 Act and the published Rules and Regulations, to the effect set forth in Schedule II hereto. (f) Except as contemplated in the Prospectus, (i) none of the Company, its subsidiaries or CN shall have sustained since the date of the latest audited financial statements included or incorporated by reference in the Prospectus any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree; and (ii) subsequent to the respective dates as of which information is given in the Registration Statement and the Prospectus, none of the Company, its subsidiaries or CN shall have incurred any liability or obligation, direct or contingent, or entered into any transactions, and there shall not have been any change in the capitalization or material increase in the short-term or long-term debt of the Company, its subsidiaries or CN or any change, or any development involving or which might reasonably be expected to involve a prospective change in the condition (financial or other), net worth, business, affairs, management, prospects, results of operations or cash flow of the Company, its subsidiaries or CN, the effect of which, in any such case described in clause (i) or (ii), is in the Underwriters' judgment so material or adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities being delivered on such Closing Date (and, if applicable, the Option Closing Date) on the terms and in the manner contemplated in the Prospectus. (g) No "nationally recognized statistical rating organization," as that term is defined by the SEC for purposes of Rule 436(g)(2) under the 1933 Act, has informed the Company that it is contemplating rating any of the Company's debt securities, including the Securities. (h) There shall not have occurred any of the following: (i) a suspension or material limitation in trading in securities generally on the New York Stock Exchange or the American Stock Exchange or The Nasdaq National Market or the establishing on such exchanges or market by the SEC or by such exchanges or markets of minimum or maximum prices which are not in force and effect on the date hereof; (ii) a suspension or material limitation in trading in the Company's 19 20 securities on the New York Stock Exchange or the establishing on such exchange by the SEC or by such exchange of minimum or maximum prices which are not in force and effect on the date hereof; (iii) a general moratorium on commercial banking activities declared by either federal or any state authorities; (iv) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war, which in the Underwriters' judgment makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities in the manner contemplated in the Prospectus; or (v) any calamity or crisis, change in national, international or world affairs, act of God, change in the international or domestic markets, or change in the existing financial, political or economic conditions in the United States or elsewhere, which in the Underwriters' judgment makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities in the manner contemplated in the Prospectus. (i) The Underwriters shall have received a certificate, dated the Closing Date (and, if applicable, the Option Closing Date) and signed by the President and the Chief Financial Officer of the Company, in their capacities as such, stating that: (i) the condition set forth in Section 6(a) has been fully satisfied; (ii) they have carefully examined the Registration Statement and the Prospectus as amended or supplemented and all documents incorporated by reference therein and nothing has come to their attention that would lead them to believe that (A) the Registration Statement or any amendment or supplement thereto or any documents incorporated by reference therein as of their respective effective, issue or filing dates, contained any untrue statement of a material fact, or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading or (B) the Prospectus as amended or supplemented when read together with the documents incorporated by reference therein, as of its issue date or as of its issue date or the Closing Date, contained or contains any untrue statement of material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; (iii) since the date of the Prospectus, there has occurred no event required to be set forth in an amendment or supplement to the Registration Statement or the Prospectus which has not been so set forth and there has been no document required to be filed under the 1934 Act and the 1934 Act Rules and Regulations that upon such filing would be deemed to be incorporated by reference into the Prospectus that has not been so filed; (iv) all representations and warranties made herein by the Company are true and correct at such Closing Date, with the same effect as if made on and as of such Closing Date, and all agreements herein to be performed or complied with by the Company, and all conditions to be satisfied by the Company on or prior to such Closing Date have been duly performed and complied with and satisfied by the Company; (v) except as disclosed in the Prospectus, none of the Company, its subsidiaries or CN has sustained since the respective dates as of which information is given in the Registration Statement and the Prospectus, any material loss or interference with its business 20 21 from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree; (vi) except as disclosed in the Prospectus, subsequent to the respective dates as of which information is given in the Registration Statement and the Prospectus, none of the Company, its subsidiaries or CN has incurred any liabilities or obligations, direct or contingent, other than in the ordinary course of business, or entered into any transactions not in the ordinary course of business, which in either case are material to the Company, such subsidiary or CN; and there has not been any change in the capitalization or material increase in the short-term debt or long-term debt of the Company, any of its subsidiaries or CN or any material adverse change or any development involving or which may reasonably be expected to involve a prospective material adverse change, in the condition (financial or other), net worth, business, affairs, management, prospects, results of operations or cash flow of the Company, its subsidiaries and CN, taken as a whole; and there has been no dividend or distribution of any kind, paid or made by the Company on any class of its capital stock (except for dividends at an annual rate of $2.125 per share with respect to the Series A Preferred Stock); and (j) The Company shall have furnished to the Underwriters at the Closing Date such further information, opinions, certificates, letters and documents as the Underwriters may have reasonably requested. (k) The Securities shall have been approved for trading upon official notice of issuance on the New York Stock Exchange. All such opinions, certificates, letters and documents will be in compliance with the provisions hereof only if they are satisfactory in form and substance to the Underwriters and to Vinson & Elkins L.L.P., counsel for the Underwriters. The Company will furnish the Underwriters with such signed and conformed copies of such opinions, certificates, letters and documents as the Underwriters may request. If any of the conditions specified above in this Section 6 shall not have been satisfied at or prior to the Closing Date (and, if applicable, the Option Closing Date) or waived by the Underwriters in writing, this Agreement may be terminated by the Underwriters on notice to the Company. 7.

In case any such action shall be brought against any such indemnified party and it shall notify each indemnifying party of the commencement thereof, each such indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party under Section 7(a) or 7(b) hereof similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of such indemnified party, be counsel to such indemnifying party), and, after notice from such indemnifying party to such indemnified party of its election so to assume the defense thereof, such indemnifying party shall not be liable to such indemnified party under Section 7(a) or 7(b) hereof for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. The indemnified party shall have the right to employ its own counsel in any such action, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the employment of counsel by such indemnified party at the expense of the indemnifying party has been authorized by the indemnifying party, (ii) the indemnified party shall have been advised by such counsel that there may be a conflict of interest between the indemnifying party and the indemnified party in the conduct of the defense, or certain aspects of the defense, of such action (in which case the indemnifying party shall not have the right to direct the defense of such action with respect to those matters or aspects of the defense on which a conflict exists or may exist on behalf of the indemnified party) or (iii) the indemnifying party shall not in fact have employed counsel reasonably satisfactory to such indemnified party to assume the defense of such action, in any of which events such fees and expenses to the extent applicable shall be borne, and shall be paid as incurred, by the indemnifying party. If at any time such indemnified party shall have requested such indemnifying party under Section 7(a) or 7(b) hereof to reimburse such 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 7(a) or 7(b) hereof effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of such request for reimbursement, (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 for reimbursement prior to the date of such settlement. No such indemnifying party shall, without the written consent of such indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not such indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (A) includes an unconditional release of such indemnified party from all liability arising out of such action or claim and (B) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any such indemnified party. In no event shall such indemnifying parties be liable for the fees and expenses of more than one counsel, including any local counsel, for all such 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. (d) If the indemnification provided for in this Section 7 is unavailable to or insufficient to indemnify or hold harmless an indemnified party under Section 7(a) or 7(b) hereof in respect of any losses, damages or liabilities (or actions or claims in respect thereof) referred to therein, then each indemnifying party under Section 7(a) or 7(b) hereof shall contribute to the amount paid or 23 24 payable by such indemnified party as a result of such losses, damages or liabilities (or actions or claims in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under Section 7(c) hereof and such indemnifying party was prejudiced in a material respect by such failure, then each such indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault, as applicable, of the Company, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions that resulted in such losses, damages or liabilities (or actions or claims in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by, as applicable, the Company, on the one hand, and the Underwriters, on the other hand, shall be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault, as applicable, of the Company, on the one hand, and the 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, on the one hand, or the Underwriters, on the other hand, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7(d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to above in this Section 7(d). The amount paid or payable by such an indemnified party as a result of the losses, damages or liabilities (or actions or claims in respect thereof) referred to above in this Section 7(d) shall be deemed to include any legal or other expenses incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of 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. The obligations of the Underwriters in this Section 7(d) to contribute are several in proportion to their respective underwriting obligations with respect to the Securities and not joint. (e) The obligations of the Company under this Section 7 shall be in addition to any liability that the Company may otherwise have and shall extend, upon the same terms and conditions, to each officer, director, employee, agent or other representative and to each person, if any, who controls any Underwriter within the meaning of the 1933 Act; and the obligations of the Underwriters under this Section 7 shall be in addition to any liability that the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company who signed the Registration Statement and to each person, if any, who controls the Company within the meaning of the 1933 Act. 24 25 8. REPRESENTATIONS AND AGREEMENTS TO SURVIVE DELIVERY. The respective representations, warranties, agreements and statements of the Company and the Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain operative and in full force and effect regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter, any officer, director, employee, agent or other representative or any controlling person of any Underwriter, or the Company, any officer or director of the Company who signed the Registration Statement or any controlling person of the Company, and shall survive delivery of and payment for the Securities. 9. TERMINATION. (a) This Agreement may be terminated by the Underwriters at any time at or prior to the Closing Date by notice to the Company if any condition specified in Section 6 hereof shall not have been satisfied on or prior to the Closing Date. Any such termination shall be without liability of any party to any other party except as provided in Sections 7 and 10 hereof. (b) This Agreement also may be terminated by the Underwriters, by notice to the Company, as to any obligation of the Underwriters to purchase the Option Securities, if any condition specified in Section 6 hereof shall not have been satisfied at or prior to the Option Closing Date. If the Underwriters terminate this Agreement as provided in Sections 9(a) or 9(b), the Underwriters shall notify the Company by telephone or telegram, confirmed by letter. 10. COSTS AND EXPENSES. The Company, whether or not the transactions contemplated hereby are consummated or this Agreement is terminated, will bear and pay the costs and expenses incident to the registration of the Securities and public offering thereof, including, without limitation, (a) the filing fees of the SEC and the fees and expenses of the Company's counsel and accountants, (b) all expenses incurred in connection with the preparation, printing, filing, delivery and shipping of the Registration Statement, the Preliminary Prospectus Supplement, the Prospectus and any amendments or supplements thereto and the printing, delivery and shipping of this Agreement and other underwriting documents, (c) the furnishing of copies of such documents to the Underwriters, (d) all expenses incurred in connection with the registration or qualification of the Securities for offering and sale under the securities laws of the various states and other jurisdictions, including the fees and disbursements of counsel to the Underwriters relating to such registration or qualification, (e) the filing fees of the NASD and fees and disbursements of counsel to the Underwriters relating to any review of the offering by the NASD, (f) the cost of the preparation, issuance and delivery of the Securities to the Underwriters, including any charges of DTC in connection therewith, (g) all fees and expenses relating to the authorization of the Securities for trading on the New York Stock Exchange, (h) all travel expenses, including air fare and accommodation expenses, of representatives of the Company in connection with the offering of the Securities, (i) the fees and disbursements of the Trustee and any agent of the Trustee and the fees and disbursements of their counsel incurred in connection with the Indenture and the Securities, and (j) all of the other costs and expenses incident to the performance by the Company of the registration and offering of the Securities. If this Agreement is terminated by the Underwriters in accordance with the provisions of Section 9, the Company shall reimburse the Underwriters for all of their out-of-pocket expenses, including the fees and disbursements of counsel to the Underwriters. 25 26 11.
