Purchase and Offering of Securities. The obligation of the Underwriters to purchase the Registered Securities will be evidenced by an exchange of telegraphic or other written communications ("Terms Agreement") at the time the Company determines to sell the Registered Securities. The Terms Agreement will generally be in the form attached hereto as Annex I and will incorporate by reference the provisions of this Agreement, except as otherwise provided therein, and will specify the firm or firms which will be Underwriters, the names of any Representatives, the principal amount to be purchased by each Underwriter, the purchase price to be paid by the Underwriters and the terms of the Registered Securities not already specified in the Indenture, including, but not limited to, interest rate, maturity, any redemption provisions and any sinking fund requirements and whether any of the Securities may be sold to institutional investors pursuant to Delayed Delivery Contracts (as defined below). The Terms Agreement will also specify the time and date of delivery and payment (such time and date, or such other time not later than seven full business days thereafter as the Representatives and the Company agree as the time for payment and delivery, being herein and in the Terms Agreement referred to as the "Closing Date"), the place of delivery and payment and any details of the terms of offering that should be reflected in the prospectus supplement relating to the offering of the Registered Securities. The obligations of the Underwriters to purchase the Registered Securities will be several and not joint. It is understood that the Underwriters propose to offer the Registered Securities for sale as set forth in the Prospectus. The Registered Securities delivered to the Underwriters on the Closing Date will be in definitive fully registered form, in such denominations and registered in such names as the Underwriters may request. Delivery of Registered Securities shall be made to the Representatives for the respective 8 accounts of the several Underwriters against payment by the several Underwriters through the Representatives of the purchase price thereof to or upon the order of the Company by wire transfer payable in same-day funds to an account specified by the Company. Delivery of Registered Securities shall be made through the facilities of The Depository Trust Company unless the Representatives shall otherwise instruct. If the Terms Agreement provides for sales of Securities pursuant to delayed delivery contracts, the Company authorizes the Underwriters to solicit offers to purchase Securities pursuant to delayed delivery contracts substantially in the form of Annex II attached hereto ("Delayed Delivery Contracts") with such changes therein as the Company may authorize or approve. Delayed Delivery Contracts are to be with institutional investors, including commercial and savings banks, insurance companies, pension funds, investment companies and educational and charitable institutions. On the Closing Date the Company will pay, as compensation, to the Representatives for the accounts of the Underwriters, the fee set forth in such Terms Agreement in respect of the principal amount of Registered Securities to be sold pursuant to Delayed Delivery Contracts ("Contract Securities"). The Underwriters will not have any responsibility in respect of the validity or the performance of Delayed Delivery Contracts. If the Company executes and delivers Delayed Delivery Contracts, the Contract Securities will be deducted from the Securities to be purchased by the several Underwriters and the aggregate principal amount of Securities to be purchased by each Underwriter will be reduced pro rata in proportion to the principal amount of Registered Securities set forth opposite each Underwriter's name in such Terms Agreement, except to the extent that the Representatives determine that such reduction shall be otherwise than pro rata and so advise the Company. The Company will advise the Representatives not later than the business day prior to the Closing Date of the principal amount of Contract Securities. 4. Certain Agreements of the Company. The Company agrees with the several Underwriters that it will furnish to Cravath, Swaine & Moore, special counsel for the Underwriters (or any other counsel named as counsel for the Underwriters in any Terms Agreement), one signed copy of the 9 Registration Statement relating to the Registered Securities, including all exhibits, in the form it became effective and of all amendments thereto and that, in connection with each offering of Securities: (a) The Company will advise the Representatives promptly of any proposal to amend or supplement the Registration Statement or the Prospectus and will afford the Representatives a reasonable opportunity to comment on any such proposed amendment or supplement; and the Company will also advise the Representatives promptly of the filing of any such amendment or supplement and of the institution by the Commission of any stop order proceedings in respect of the Registration Statement or of any part thereof and will use its best efforts to prevent the issuance of any such stop order and to obtain as soon as possible its lifting, if issued. (b) If, at any time when a prospectus relating to the Securities is required to be delivered under the 1933 Act, any event occurs as a result of which the Prospectus as then amended or supplemented would include an untrue statement of a material fact or 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, or if it is necessary at any time to amend the Prospectus to comply with the 1933 Act, the Company promptly will prepare and file with the Commission an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance. (c) As soon as practicable, the Company will make generally available to its security holders and to the Representatives an earnings statement or statements of the Company and its subsidiaries which will satisfy the provisions of Section 11(a) of the 1933 Act and Rule 158 under the 1933 Act. (d) The Company will furnish to the Representatives copies of the Registration Statement, including all exhibits, any related preliminary prospectus, any related preliminary prospectus supplement, the Prospec- 10 tus and all amendments and supplements to such documents, in each case as soon as available and in such quantities as are reasonably requested. (e) The Company will arrange for the qualification of the Registered Securities for sale and the determination of their eligibility for investment under the laws of such jurisdictions as the Representatives designate and will continue such qualifications in effect so long as required for the distribution. (f) During the period of 5 years after the date of any Terms Agreement, the Company will furnish to the Representatives and, upon request, to each of the other Underwriters, if any, as soon as practicable after the end of each fiscal year, a copy of its annual report to stockholders for such year; and the Company will furnish to the Representatives (i) as soon as available, a copy of each report or definitive proxy statement of the Company filed with the Commission under the 1934 Act or mailed to stockholders and (ii) from time to time, such other information concerning the Company as the Representatives may reasonably request. (g) The Company will pay all reasonable expenses incident to the performance of its obligations under this Agreement and will reimburse the Underwriters for any expenses (including reasonable fees and disbursements of counsel) incurred by them in connection with qualification of the Registered Securities for sale and determination of their eligibility for investment under the laws of such jurisdictions as the Representatives may designate and the printing of memoranda relating thereto, for any fees charged by investment rating agencies for the rating of the Securities and for expenses incurred in distributing the Prospectus, any preliminary prospectuses and any preliminary prospectus supplements to Underwriters. (h) For a period beginning at the time of execution of the Terms Agreement and ending 10 days after the Closing Date, without the prior consent of the Representatives, the Company will not offer, sell, 11 contract to sell or otherwise dispose of any United States dollar-denominated debt securities issued or guaranteed by the Company and having a maturity of more than one year from the date of issue. 5.

(iv) On the basis of a reading of the unaudited pro forma financial statements included or incorporated in the Registration Statement, if any, and the Prospectus (the "pro forma financial statements"), carrying out certain specified procedures; inquiries of certain officials of the Company who have responsibility for financial and accounting matters, and proving the arithmetic accuracy of the application of the pro forma 20 adjustments to the historical amounts in the pro forma financial statements, nothing came to their attention that caused them to believe that the pro forma financial statements do not comply in form in all material respects with the applicable accounting requirements of Rule 11-02 of Regulation S-X of the Rules and Regulations. (v) In addition to the examination referred to in their report included or incorporated by reference in the Registration Statement and the Prospectus, and the limited procedures referred to in clause (iii) above, they have carried out certain other specified procedures, not constituting an audit, with respect to certain amounts, percentages and financial information which are included or incorporated by reference in the Registration Statement and Prospectus and which are specified by the Representatives, and have found such amounts, percentages and financial information to be in agreement with the relevant accounting, financial and other records of the Company and its subsidiaries identified in such letter.

Indemnification and Contribution. (a) The Company will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the 1933 Act or otherwise, insofar as such losses, claims, 21 damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus or preliminary prospectus supplement, 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 not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter 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 an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives, if any, specifically for use therein. (b) Each Underwriter will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the 1933 Act 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 any material fact contained in the Registration Statement, the Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus or preliminary prospectus supplement, or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives, if any, specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred. 22 (c) Promptly after receipt by an indemnified party under this Section 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 subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. (d) If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) 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 from the offering of the Securities or (ii) if the allocation provided by clause (i) above 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 Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters 23 on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault 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 the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (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 which 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 Underwriters' obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint. (e) The obligations of the Company under this Section shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, 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 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company, to each officer of the Company who has signed the Registration Statement and to each person, if any, who controls the 24 Company within the meaning of the 1933 Act. 7. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Securities under the Terms Agreement and the aggregate principal amount of the Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total principal amount of the Securities, the Representatives may make arrangements satisfactory to the Company for the purchase of such Securities by other persons, including any of the Underwriters, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments under this Agreement and the Terms Agreement, to purchase the Securities that such defaulting Underwriters agreed but failed to purchase. If any Underwriter or Underwriters so default and the aggregate principal amount of the Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of the Securities and arrangements satisfactory to the Representatives and the Company for the purchase of such Securities by other persons are not made within 36 hours after such default, such Terms Agreement will terminate without liability on the part of any nondefaulting Underwriter or the Company, except as provided in Section 8. As used in this Agreement, the term "Underwriter" includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default. The respective commitments of the several Underwriters for the purposes of this Section shall be determined without regard to reduction in the respective Underwriters' obligations to purchase the principal amounts of the Securities set forth opposite their names in the Terms Agreement as a result of Delayed Delivery Contracts entered into by the Company. The foregoing obligations and agreements set forth in this Section will not apply if the Terms Agreement specifies that such obligations and agreements will not apply. 8. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the 25 Company or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Securities. If the Terms Agreement is terminated pursuant to Section 7 or if for any reason the purchase of the Securities by the Underwriters under the Terms Agreement is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 4 and the respective obligations of the Company and the Underwriters pursuant to Section 6 shall remain in effect. If the purchase of the Securities by the Underwriters is not consummated for any reason other than because of the termination of the Terms Agreement pursuant to Section 7 or the occurrence of any event specified in Section 5(b), the Company will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Securities. 9. Notices. All communications hereunder will be in writing and, if sent to the Underwriters, will be mailed, delivered or telegraphed and confirmed to them at their addresses furnished to the Company in writing for the purpose of communications hereunder or, if sent to the Company, will be mailed, delivered or telegraphed and confirmed to it at 801 Cherry Street, Fort Worth, Texas 76102, Attention: Treasurer. 10.
