(a) Subject to the terms and conditions and on the basis of the representations and warranties set forth herein, the Company agrees to appoint [each of] you as its agent to solicit offers for the purchase of all or part of the Securities and [each of] you[, severally and not jointly,] agree[s], as agent of the Company, to use your best efforts to solicit such offers. The Company agrees that whenever it determines to sell Securities directly to you as principal for resale to others it will, at your request, enter into a Terms Agreement relating to such sale in accordance with the provisions of Section 2(b) hereof. The Company agrees to pay [each of] the Agent[s] the commissions set forth in Schedule I hereto as compensation for Securities purchased as a result of solicitations made by [such] [the] Agent [,provided that the Company shall not be liable to more than one Agent for commissions with respect to any sale]. The Agent[s] shall communicate to the Company, by telephone, each offer to 4 4 purchase Securities other than those rejected by the Agent[s]. The Company shall have the right, in its sole discretion, to accept offers to purchase Securities and may reject any proposed purchase of Securities as a whole or in part. [Each of the] [The] Agent[s] shall have the right, in its discretion reasonably exercised, to reject any proposed purchase of Securities, as a whole or in part, and any such rejection shall not be deemed a breach of its agreements and obligations herein. Administrative procedures with respect to the sale of Securities shall be agreed upon in writing from time to time by the Company and the Agent[s] (the "Procedures") and shall be initially as agreed upon in writing as of the Closing Date (as defined below). [Each of the] [The] Agent[s] and the Company agree[s] to perform [its] [their] respective duties and obligations provided for herein and in the Procedures. The Procedures may only be amended by the Company and the Agent[s] by written agreement. The Company reserves the right, in its sole discretion, to instruct the Agent[s] to suspend solicitations of offers to purchase Securities at any time for any period of time or permanently. Upon receipt of such instruction, the Agent[s] will forthwith suspend solicitation of offers to purchase Securities until such time as the Company has advised the Agent[s] that such solicitation may be resumed. (b) Each sale of Securities to [each of] you as principal shall be made in accordance with the terms of this Agreement and, at your request, a separate agreement which will provide for the sale of such Securities to, and the purchase and reoffering thereof by, you. Each such separate agreement (which shall be substantially in the form of Exhibit A hereto and which may take the form of an exchange of any standard form of written telecommunication between you and the Company) is herein referred to as a "Terms Agreement". Your commitment to purchase Securities pursuant to any Terms Agreement shall be deemed to have been made on the basis of the representations and warranties of the Company herein contained and shall be subject to the terms and conditions herein set forth. Each Terms Agreement shall specify the principal amount of Securities to be purchased by you pursuant thereto, the price to be paid to the Company for such Securities, the initial public offering price, if any, at which the Securities are proposed to be reoffered and the time and place of delivery of any payment for such 5 5 Securities (each such time, as well as any delivery date under the Procedures, a "Settlement Date"). Such Terms Agreement shall also specify any requirements for an opinion of counsel, officers' certificate and letter from Deloitte & Touche pursuant to Section 5 hereof.

(d) So long as this Agreement shall remain in effect with respect to [any] [the] Agent, the Company shall not, without the consent of [any such] [the] Agent, solicit or accept offers to purchase Securities otherwise than through [one of] the Agent[s] (except as contemplated by Section 2(b) hereof); provided, however, that, subject to all the terms and conditions of this Agreement and any agreement contemplated by Section 2(b) hereof, the foregoing shall not be construed to prevent the Company from (i) selling at any time any Securities in a firm commitment underwriting pursuant to an underwriting agreement that does not provide for a continuous offering of such Securities, (ii) making any direct sales of Securities to entities which are not brokers and are purchasing only for investment purposes and not for resale or (iii) selling Securities to or through an agent, other than [an] [the] Agent, where the Company has entered into an agreement with such agent with substantially identical terms, conditions and obligations as this Agreement. 3. Closing Date. The documents required to be delivered pursuant to Section 5 hereof shall be delivered at the offices of Cravath, Swaine & Moore, 825 Eighth Avenue, New York, N.Y. 10019, on the date hereof, or at such other time as the Company and the Agent[s] may agree upon in writing (the "Closing Date"). 6 6 4. Covenants of the Company. In connection with each offering of Securities, the Company covenants and agrees with the Agent[s] that: (a) The Company will advise the Agent[s] promptly of any proposal to amend or supplement the Registration Statement or the Prospectus, will afford the Agent[s] a reasonable opportunity to comment on any such proposed amendment or supplement and will not effect such amendment or supplement without the consent of the Agent[s] (which will not be unreasonably withheld). The Company will also advise the Agent[s] 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, and will use its best efforts to prevent the issuance of any such stop order and to obtain as soon as possible the lifting of any such order. (b) If at any time when a prospectus relating to the Securities is required to be delivered under the 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 shall be necessary, in the opinion of the Company or in the reasonable opinion of counsel for the Agent[s], to amend or supplement the Registration Statement or the Prospectus to comply with the Act or the Rules and Regulations, the Company will notify the Agent[s] promptly to suspend solicitation of purchases of the Securities; and, forthwith upon receipt of such notice, the Agent[s] shall suspend [its] [their] solicitation of purchases of the Securities and shall cease using the prospectus which has been most recently distributed to the Agent[s] by the Company; and, if the Company shall decide to amend or supplement the Registration Statement or the Prospectus, it will promptly advise the Agent[s] by telephone (with confirmation in writing) and will promptly 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, and will advise the Agent[s] when the Agent[s] [are] [is] free to resume such solicitation. Notwithstanding the foregoing, if, at the time of any notification to suspend solicitations, [any] 7 7 [the] Agent shall own any of the Securities with the intention of reselling them, or the Company has accepted an offer to purchase Securities but the related settlement has not occurred, the Company, subject to the provisions of subsection (a) of this Section, will promptly 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) So long as a prospectus relating to the Securities is required to be delivered, or may in the future be required to be delivered, under the Act, on or prior to the date on which the Company makes an announcement to the general public concerning earnings or concerning any other event which is required to be described, or which the Company proposes to describe, in a document filed pursuant to the Exchange Act, the Company will furnish the information contained or to be contained in such announcement to [each] [the] Agent, confirmed in writing, and, if the provisions of subsections (a) and (b) of this Section would so require, will subsequently cause the Prospectus to be amended or supplemented to reflect the information contained in such announcement. The Company also will furnish [each] [the] Agent with copies of all other press releases or announcements to the general public. The Company will immediately notify [each] [the] Agent of any downgrading in the rating of the Securities or any other debt securities of the Company, or any proposal to downgrade the rating of the Securities or any other debt securities of the Company, by any "nationally recognized statistical rating organization" (as defined for purposes of Rule 436(g) under the Act), as soon as the Company learns of such downgrading or proposal to downgrade. (d) The Company will furnish to Cravath, Swaine & Moore, counsel for the Agent[s], one copy of the signed Registration Statement, including all exhibits, relating to the Securities in the form it became effective and of all amendments thereto and will furnish to [each] [the] Agent copies of the Registration Statement, the Prospectus, and all amendments and supplements to such documents, in each case as soon as available and in such quantities as [such] [the] Agent may reasonably request. (e) The Company will use its best efforts to 8 8 arrange for the qualification of the Securities for sale under the laws of such jurisdictions as the Agent[s] may designate and will continue such qualifications in effect so long as required for the distribution, and the Company will use its best efforts to arrange for the determination of their eligibility for investment by institutional investors; provided, however, that the Company shall not be required to qualify to do business in any jurisdiction where it is not now qualified or to take any action which would subject it to general or unlimited service of process in any jurisdiction where it is not now subject. (f) As soon as practicable, the Company will make generally available to its security holders and to the Agent[s] an earnings statement or statements of the Company and its subsidiaries which will satisfy the provisions of Section 11(a) of the Act and Rule 158 under the Act. (g) The Company will pay all expenses incident to the performance of its obligations under this Agreement, will reimburse the Agent[s] for any expenses (including fees and disbursements of counsel) incurred by [it] [them] in connection with qualification of the Securities for sale and determination of their eligibility for investment under the laws of such jurisdictions as the Agent[s] may designate and will pay the expenses of printing all documents relating to the offering and of the mailing and delivering of copies thereof to the Agent[s] and any fees charged by investment rating agencies for rating the Securities. Except as otherwise provided herein and in Section 11 hereof, the Agent[s] will pay all their own costs and expenses, other than fees and costs of their counsel, which will be paid by the Company. (h) Between the date of any Terms Agreement and the Settlement Date with respect to such Terms Agreement, the Company will not, without the Agent[s']['s] prior consent, offer or sell, or enter into any agreement to sell (other than, in any such case, a sale through [an] [the] Agent) any debt securities of the Company with terms substantially similar to the Securities which are to be sold pursuant to such Terms Agreement (other than such Securities and commercial paper sold in the ordinary course of business), except as may otherwise be provided in any such Terms Agreement. 9 9 5.

The obligations of the Agent[s] to proceed hereunder shall be subject to the condition that all representations and warranties of the Company herein are, at and as of the date hereof, as of the Closing Date, as of each Settlement Date with respect to any applicable Terms Agreement and as of each Settlement Date under the Procedures, true and correct, the condition that the Company shall have performed all its obligations hereunder theretofore to be performed, and the following additional conditions: (a) Neither the Registration Statement nor the Prospectus, as amended or supplemented as of any Representation Date, shall contain any untrue statement of fact which is material or omit to state a fact which is material and is required to be stated therein or is necessary to make the statements therein not misleading.

(e) The Agent[s] shall have received the following: (i) An opinion, dated the Closing Date, of the Senior Vice President and General Counsel or the Assistant General Counsel of the Company, or other counsel satisfactory to the Agent[s], to the effect that: (A) the Company has been duly incorporated and is an existing corporation in good standing under the laws of the State of Utah, with corporate power and authority to own its properties and conduct its business as described in the Prospectus; and the Company is duly qualified to do business as a foreign corporation in good standing in all other jurisdictions in which it owns or leases substantial properties; (B) the Indenture has been duly authorized, executed and delivered by the Company and has been duly qualified under the Trust Indenture Act; the Securities have been duly authorized; the Indenture constitutes, and the Securities, when executed, authenticated, issued and delivered in the manner provided in the Indenture and sold pursuant to this Agreement or any Terms Agreement, will constitute, valid and legally binding obligations of the Company, enforceable in accordance with their terms, subject, as to enforcement, to bankruptcy, insolvency, reorganization and other laws of general applicability relating to or affecting creditors' rights and to general equity principles; and the Securities, when so issued and delivered and sold, will conform to the description thereof contained in the Prospectus; 12 12 (C) no consent, approval, authorization or order of, or filing with, any governmental agency or body or any court is required for the consummation of the transactions contemplated by this Agreement or any Terms Agreement, except (i) such as have been obtained and made under the Act and the Trust Indenture Act and (ii) such as may be required under state securities laws in connection with the issuance or sale of the Securities by the Company; (D) the execution, delivery and performance of the Indenture, this Agreement and any Terms Agreement and the issuance and sale of the Securities and compliance with the terms and provisions thereof will not result in a breach or violation of any of the terms and provisions of, or constitute a default under, any statute, any rule, regulation or order of any governmental agency or body or any court having jurisdiction over the Company or any of its properties or any agreement or instrument to which the Company is a party or by which the Company is bound or to which any of the properties of the Company is subject, or the charter or By-laws of the Company, and the Company has full power and authority to authorize, issue and sell the Securities as contemplated by this Agreement and any Terms Agreement; (E) the Registration Statement has become effective under the Act, and, to the best of the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement or of any part thereof has been issued and no proceedings for that purpose have been instituted or are pending or contemplated under the Act, and the Registration Statement, as of the Effective Date, the Registration Statement and the Prospectus as amended or supplemented, as of the Closing Date, and any further amendment or supplement thereto, as of its date, complied as to form in all material respects with the requirements of the Act, the Trust Indenture Act and the Rules and Regulations; such counsel has no reason to believe that such Registration 13 13 Statement, as of the Effective Date, the Registration Statement or the Prospectus as amended or supplemented, as of the Closing Date, or any such amendment or supplement, as of its date, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading; the descriptions in the Registration Statement and the Prospectus as amended or supplemented of statutes, legal and governmental proceedings and contracts and other documents fairly present the information required to be shown; and such counsel does not know of any legal or governmental proceedings required to be described in the Prospectus as amended or supplemented which are not described as required or of any contracts or documents of a character required to be described in the Registration Statement or the Prospectus as amended or supplemented or to be filed as exhibits to the Registration Statement which are not described and filed as required, it being understood that such counsel need express no opinion as to the financial statements or other financial data contained in the Registration Statement or the Prospectus as amended or supplemented; and (F) this Agreement has been duly authorized, executed and delivered by the Company.

Indemnification and Contribution. (a) The Company will indemnify and hold harmless [each] [the] Agent against any losses, claims, damages or liabilities, joint or several, to which [such] [the] Agent 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 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] [the] Agent for any legal or other expenses reasonably incurred by [such] [the] Agent 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] [the] Agent specifically for use therein. (b) [Each] [The] Agent will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company 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 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] [the] Agent specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the 20 20 Company in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred. (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 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 Agent[s] 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 Agent[s] on the other in connection with the statements or omissions which resulted in such losses, 21 21 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 Agent[s] 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 discounts and commissions received by the Agent[s]. 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 Agent[s] 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] [the] Agent shall [not] be required to contribute any amount in excess of the amount by which the total price at which the Securities purchased through it and distributed to the public were offered to the public exceeds the amount of any damages which [such] [the] Agent has otherwise been required to pay by reason of [such] [the] 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. [The Agents' obligations in this subsection (d) to contribute are several in proportion to the respective aggregate principal amounts of Securities sold through each and are 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] [the] Agent within the meaning of the Act; and the obligations of the Agent[s] under this Section shall be in addition to any liability which the [respective] Agent[s] may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company, to each officer 22 22 of the Company who has signed the Registration Statement and to each person, if any, who controls the Company within the meaning of the Act. 8. Default by Company. If the Company shall default in its obligation to deliver Securities to a purchaser whose offer it has accepted, the Company (i) shall hold the Agent[s] harmless against any loss, claim or damage arising from or as a result of such default by the Company, and (ii) in particular, shall pay to the Agent[s] any commission to which they would be entitled in connection with such sale. 9. Status of [Each] [the] Agent. In soliciting offers to purchase the Securities from the Company pursuant to this Agreement and in assuming its other obligations hereunder (other than offers to purchase pursuant to Section 2(b)), [each] [the] Agent is acting individually and not jointly and is acting solely as agent for the Company and not as principal. [Each] [The] Agent will make reasonable efforts to assist the Company in obtaining performance by each purchaser whose offer to purchase Securities from the Company has been solicited by [such] [the] Agent and accepted by the Company, but [such] [the] Agent shall have no liability to the Company in the event any such purchase is not consummated for any reason. 10. Survival of Representations. The respective indemnities, agreements, representations, warranties and other statements of the Agent[s] and the Company set forth in this Agreement or made by 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 the Agent[s] or the Company or any of its officers or directors or any controlling person, and shall survive each delivery of and payment for any of the Securities. 11. Termination. This Agreement may be terminated at any time by the Company as to [any or all] [the] Agent[s] or any or all of the Securities (other than any Securities that are subject to a Terms Agreement) or by [any] [the] Agent as to itself upon the giving of written notice of such termination to the other parties hereto. In the event of any such termination, no party shall have any 23 23 liability to the other parties hereto, except as provided in the third sentence of Section 2(a), Section 4(g), Section 7, Section 8, Section 9 and Section l0 and except that, if at the time of termination (A) the Agent[s] shall own any of the Securities with the intention of reselling them or (B) an offer to purchase any of the Securities has been accepted by the Company but the time of delivery to the purchaser or the purchaser's agent of the Security or Securities relating thereto has not occurred, the covenants set forth in Sections 4 and 6 hereof shall remain in effect until such Securities are so resold or delivered, as the case may be. 12. Notices. Except as otherwise specifically provided herein or in the Procedures, all statements, requests, notices and advices hereunder shall be in writing, and shall be sufficient in all respects if delivered or sent by telecopier or registered mail, if to the Agent[s], at [its] [their] [respective] address[es] on the first page hereof, to the attention of, in the case of , and if sent to the Company, at Eighth and Eaton Avenues, Bethlehem, Pennsylvania 18018, Attention of Vice President and Treasurer. 13. Miscellaneous. This Agreement may be executed in two or more counterparts and it is not necessary that signatures of all parties appear on the same counterpart, but such counterparts together shall constitute but one and the same agreement. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors, and no other person will have any right or obligation hereunder.
