(ix) The execution and delivery by the Company of this Agreement, the Indenture, the Registration Rights Agreement, the issuance and delivery of the Securities, the Company Purchase Option, the consummation by the Company of the transactions contemplated herein and the compliance by the Company with the terms of this Agreement, the Indenture, the Registration Rights Agreement, the Company Purchase Option and the Securities have been duly authorized by all necessary corporate action on the part of the Company and do not and will not result in any violation of the charter or by-laws of the Company, and do not and will not conflict with, or result in a breach of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company is a party or by which the Company is bound (except for such conflicts, breaches or defaults that could not reasonably be expected to have a Material Adverse Effect), nor does or will such action result in any violation of the charter or by-laws of the Company or any statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction over the Company or any of its properties; and no consent, approval, authorization, order, registration or qualification of or with any such court or governmental agency or body is required for the issuance and sale of the Securities or the consummation by the Company of the transactions contemplated by the Registration Rights Agreement, the Company Purchase Option, this Agreement or the Indenture; (x) Neither the Company nor any of its Significant Subsidiaries is in violation of its charter or by-laws or in default in the performance or observance of any material obligation, agreement, covenant or condition contained in any contracts, indenture, mortgage, deed of trust, loan agreement, lease or other agreement or instrument to which it is a party; 14 15 (xi) The Company is not an "investment company," as such term is defined in the Investment Company Act; (xii) The Company has filed all documents with the Commission that it is required to file under the Securities Act and the Exchange Act, as applicable, and the rules and regulations of the Commission thereunder, and such documents (other than the financial statements, including the notes thereto, and related schedules therein, and the other financial and accounting data, as to which such counsel need express no opinion) conformed in all material respects to the requirements of the Securities Act or the Exchange Act, as applicable, and the rules and regulations of the Commission thereunder; and such counsel has no reason to believe that any of such documents, when they became effective and were so filed, as the case may be, contained, in the case of a registration statement which became effective under the Securities Act or Exchange Act, 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, in the case of other documents which were filed under the Securities Act or the Exchange Act with the Commission, an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made when such documents were so filed, not misleading; (xiii) The statements in the Offering Memorandum under the captions "Description of the Securities," insofar as they purport to constitute a summary of the terms of the Securities and "Plan of Distribution," insofar as they purport to describe the legal matters and documents referred to therein, fairly summarize in all material respects the matters referred to therein; (xiv) After due inquiry, such counsel does not know of any legal or governmental proceedings pending or threatened to which the Company is a party or to which any of the properties of the Company is subject that are required to be described in the Offering Memorandum and are not so described or of any statutes, regulations, contracts or other documents that are required to be described in the Offering Memorandum that are not described as required; (xv) Such counsel has no reason to believe that (except for financial statements and schedules and related notes thereto, and the other financial and accounting data as to which such counsel need not express any belief) the Offering Memorandum contains any untrue statement of a material fact or omits to state 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 15 16 (xvi) Assuming the accuracy of the representations of the Initial Purchasers contained in Section 4 hereof and the Selling Securityholder in Section 2 hereof, compliance by the Initial Purchasers and the Selling Securityholder with the offering and transfer procedures and restrictions described in the Offering Memorandum, the accuracy of the representations and warranties deemed to be made in the Offering Memorandum by purchasers to whom the Initial Purchasers initially resell the Securities and that purchasers to whom the Initial Purchasers initially resell the Securities receive a copy of the Offering Memorandum prior to such sale, it is not necessary in connection with the offer, sale and delivery of the Securities in the manner contemplated in this Agreement to register the Securities under the Securities Act or to qualify the Indenture under the Trust Indenture Act of 1939, as amended. (b) Counsel (which may be in-house counsel) for the Selling Securityholder, shall have furnished to the Initial Purchasers an opinion, dated the Time of Delivery, in form and substance satisfactory to the Initial Purchasers, to the effect that: (i) This Agreement has been duly authorized, executed and delivered by the Selling Securityholder; (ii) The Selling Securityholder had full right, power and authority to sell and deliver the Securities sold by it in accordance with the provisions of this Agreement; and (iii) Upon delivery to DTC or its agent of the Securities sold by the Selling Securityholder registered in the name of Cede & Co., as nominee for DTC, and upon the payment of the purchase price for such Securities and the crediting by DTC of such Securities to the securities accounts of the Initial Purchasers with DTC, the Initial Purchasers will acquire a valid entitlement (within the meaning of Section 8-501 of the New York Uniform Commercial Code) in respect of the Securities to be purchased by it, and no action (whether framed in conversion, replevin, constructive trust, equitable lien, or other theory) based on an adverse claim to such Securities may be asserted against the Initial Purchasers (assuming that the Initial Purchasers are without notice of any adverse claim). (c) The Initial Purchasers shall have received at the Time of Delivery an opinion of Shearman & Sterling, counsel for the Initial Purchasers, dated the Time of Delivery, covering the matters referred to in subparagraphs (iv), (v) and (vi) of subsection (a) above and the accuracy and completeness of the statements set forth in the Offering Memorandum under the captions "Description of the Securities," insofar as they purport to constitute a summary of the terms of the Securities, and "Plan of Distribution," insofar as they purport to describe the documents referred to therein, as well as such other matters as the Initial Purchasers may reasonably request, and such counsel shall have received such documents and information as they may reasonably request to enable them to pass upon such matters. 16 17 (d) The Initial Purchasers shall have received at the time of execution of this Agreement a letter, dated the date hereof, in form and substance satisfactory to the Initial Purchasers, from Ernst & Young LLP, independent public accountants, containing statements and information of the type ordinarily included in accountants' "comfort letters" to the Initial Purchasers with respect to the financial statements and certain financial information contained in the Offering Memorandum. (e) With respect to the letter of Ernst & Young referred to in the preceding paragraph and delivered to the Initial Purchasers on the date hereof (the "Initial Letter"), the Initial Purchasers shall have received at the Time of Delivery a letter (the "Bring Down Letter") from Ernst & Young, dated the Time of Delivery (i) stating as of the date of such Bring Down Letter the conclusions and findings of such firm with respect to the financial information and other matters covered by the Initial Letter and (ii) confirming in all material respects the conclusions and findings set forth in the Initial Letter. (f) (i) Neither the Company nor any of its Significant Subsidiaries shall have sustained, since the date of the latest audited financial statements included in or incorporated by reference in the Offering Memorandum, 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, which would result in any material adverse change, or any development involving a prospective material adverse change, in or affecting the general affairs, management, financial position, stockholders' equity or results of operations of the Company and its subsidiaries, taken as a whole, otherwise than as set forth or contemplated in the Offering Memorandum, and (ii) since the respective dates as of which information is given in the Offering Memorandum, there shall not have been any change in the capital stock (other than pursuant to the Company's common stock repurchase program, or its dividend reinvestment and other common stock plans) or long-term debt of the Company or any of its Significant Subsidiaries or any material adverse change, or any development involving a prospective material adverse change, in or affecting the general affairs, management, financial position, stockholders' equity or results of operations of the Company and its Significant Subsidiaries, taken as a whole, otherwise than as set forth in the Offering Memorandum, as of the date of this Agreement, the effect of which, in any such case described in clause (i) or (ii), is in the judgment of the Initial Purchasers so material and adverse as to make it impracticable or inadvisable to proceed with the sale or the delivery of the Securities on the terms and in the manner contemplated in the Offering Memorandum; (g) During the period beginning on the date hereof and ending at the Time of Delivery, (i) no downgrading shall have occurred in the rating accorded the debt securities or preferred stock of the Company by any "nationally recognized statistical rating organization," as that term is defined by the Commission for purposes of Rule 436(g)(2) under the Securities Act, and (ii) no such organization shall have publicly 17 18 announced that it has under surveillance or review, with possible negative implications, its rating of any of the debt securities or preferred stock of the Company; (h) During the period beginning on the date hereof and ending at the Time of Delivery, 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 establishment of minimum prices on such exchange; (ii) a suspension or material limitation in trading in the Company's securities on the New York Stock Exchange; (iii) a general moratorium on commercial banking activities declared by either Federal or New York State authorities; (iv) a material disruption of the United States government securities market, United States corporate bond market or the United States federal wire transfer system; and (v) an outbreak or escalation of hostilities involving the United States or the declaration of a national emergency or war by the United States, if the effect of any such event specified in this clause (h) in the judgment of the Initial Purchasers makes it impracticable or inadvisable to proceed with the sale or the delivery of the Securities; and (i) The Company shall furnish, or cause to be furnished to the Initial Purchasers, at the Time of Delivery, a certificate or certificates of officers of the Company satisfactory to the Initial Purchasers (i) as to the accuracy of the representations and warranties of the Company herein at and as of such Time of Delivery, (ii) as to the performance by the Company of all of its obligations hereunder to be performed at or prior to such Time of Delivery, (iii) as to the matters set forth in clauses (i) and (ii) of subsection (f) of this Section and (iv) as to such other matters as the Initial Purchasers may reasonably request. (j) The Company and the Initial Purchaser shall have entered into a letter agreement satisfactory to the Initial Purchaser, substantially in the form of Exhibit A hereto (the "Company Purchase Option"). 8. (a) The Company agrees to indemnify and hold harmless the Selling Securityholder and each Initial Purchaser against any losses, claims, damages or liabilities, joint or several, to which such Securityholder or Initial Purchaser, as the case may be, may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Offering Memorandum, or any amendment 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 not misleading, and will reimburse such Selling Securityholder or Initial Purchaser, as the case may be, for any legal or other expenses reasonably incurred by such Selling Securityholder or Initial Purchaser in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall 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 or omission or alleged omission made in the 18 19 Offering Memorandum, or any such amendment or supplement thereto, in reliance upon and in conformity with written information relating to the Selling Securityholder or any Initial Purchaser furnished to the Company by the Selling Securityholder or such Initial Purchasers, as the case may be, expressly for use in the Offering Memorandum as amended or supplemented. (b) The Selling Securityholder agrees to indemnify and hold harmless the Company and each Initial Purchaser against any losses, claims, damages or liabilities, joint or several, to which such Company or Initial Purchaser may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Offering Memorandum, or any amendment 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 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 the Offering Memorandum, or any amendment or supplement thereto in reliance upon and in conformity with written information relating to the Selling Securityholder furnished to the Company by the Selling Securityholder expressly for use therein; and will reimburse the Company and each Initial Purchaser for any legal or other expenses reasonably incurred by the Company or such Initial Purchaser in connection with investigating or defending any such action or claim as such expenses are incurred; (c) Each Initial Purchaser agrees to indemnify and hold harmless the Company and the Selling Securityholder against any losses, claims, damages or liabilities to which the Company or the Selling Securityholder may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Offering Memorandum, or any amendment 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 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 the Offering Memorandum, or any amendment or supplement thereto in reliance upon and in conformity with written information relating to such Initial Purchaser furnished to the Company by such Initial Purchaser expressly for use therein; and will reimburse the Company and the Selling Securityholder for any legal or other expenses reasonably incurred by the Company or the Selling Securityholder in connection with investigating or defending any such action or claim as such expenses are incurred. (d) Promptly after receipt by an indemnified party under subsection (a), (b) or (c) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In 19 20 case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall 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 shall not be liable to such indemnified party under such subsection 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. No indemnifying party shall, without the written consent of the 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 the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party. (e) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Selling Securityholder and the Company on the one hand and the Initial Purchasers on the other to which such loss, claim, damage or liability (or action in respect thereof) relates. 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 subsection (d) above, then each 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 of the Selling Securityholder and the Company on the one hand and the Initial Purchasers of the Securities on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Selling Securityholder and the Company on the one hand and the Initial Purchasers on the other shall be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Company and the Selling Securityholder bear to the total commissions received by the Initial Purchasers. The relative benefits received by the Company on the one hand and the Selling Securityholder on the other shall be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Company and the Selling Securityholder bear to the total commissions received by the Initial Purchasers. The relative fault shall be 20 21 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 Selling Securityholder and the Company on the one hand or such Initial Purchasers on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Selling Securityholder and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this subsection (e) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (e), no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the total price at which the Securities sold by it exceeds the amount of any damages which such Initial Purchaser has otherwise been required to pay by reason of such an untrue or alleged untrue statement or omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. (f) The obligations of the Selling Securityholder or the Company under this Section 8 shall be in addition to any liability which the Selling Securityholder or the Company, as the case may be, may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Initial Purchasers within the meaning of the Act; and the obligations of the Initial Purchasers under this Section 8 shall be in addition to any liability which the respective Initial Purchasers may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Selling Securityholder or the Company, as the case may be, and to each person, if any, who controls the Selling Securityholder or the Company, as the case may be, within the meaning of the Act. 9. The respective agreements, representations, warranties and other statements of the Company, the Selling Securityholder and the Initial Purchasers as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Initial Purchaser or any controlling person of such Initial Purchaser or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Securities. 10. All statements, requests, notices and agreements hereunder shall be in writing, and if to the Selling Securityholder shall be delivered or sent by mail, telex or facsimile transmission to UBS AG, London Branch, c/o UBS Warburg LLC, 677 Washington Boulevard, Stamford, CT 06901, Attn: William Sullivan, facsimile number: 203-719-7319; if to the Initial Purchasers by mail, telex or facsimile transmission to UBS Warburg LLC, 677 Washington Boulevard, 21 22 Stamford, CT 06901, Attn: Scott Giese, facsimile number: 203-719-7319; and if to the Company shall be delivered or sent by mail, telex or facsimile transmission to The Williams Companies, Inc., One Williams Center, Tulsa, Oklahoma 74172, Attn: Treasurer, facsimile number: 918-573-2065. Any such statements, requests, notices or agreements shall take effect upon receipt thereof. 11. This Agreement shall be binding upon, and inure solely to the benefit of, the Initial Purchasers, the Selling Securityholder and the Company, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Securities from the Initial Purchasers shall be deemed a successor or assign by reason merely of such purchase. 12. If the Company fails or refuses to comply with the terms or to fulfill any of the conditions of this Agreement other than by reason of default by the Initial Purchasers or Selling Securityholder, the Company will reimburse the Initial Purchasers for all out-of-pocket expenses approved in writing by the Initial Purchasers, including fees and disbursements of counsel, reasonably incurred by the Initial Purchasers in making preparations for the purchase of the Securities. 13. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. 14. This Agreement may be executed by any one or more of the parties hereto and thereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument. 22 23 If the foregoing is in accordance with your understanding, please sign and return to us 6 counterparts hereof.
