The Securities are to be issued pursuant to an indenture dated as of March 1, 2001 (the "Indenture") between the Company and Bank One, NA, as trustee (the "Trustee"). The term "Indenture," as used herein, includes the Officer's Certificate (as defined in the Indenture) establishing the form and terms of the Securities pursuant to Sections 201 and 301 of the Indenture. Securities issued in book-entry form will be issued to Cede & Co. as nominee of The Depository Trust Company ("DTC") pursuant to a letter agreement, to be dated as of the Closing Time (as defined in Section 2(b) hereof) (the "DTC Agreement"), among the Company, the Trustee and DTC.

The Company understands that the Initial Purchasers propose to make an offering of the Securities on the terms and in the manner set forth herein and agrees that the Initial Purchasers may resell, subject to the conditions set forth herein, all or a portion of the Securities to purchasers ("Subsequent Purchasers") at any time after this Agreement has been executed and delivered. The Securities are to be offered and sold through the Initial Purchasers without being registered under the Securities Act of 1933, as amended (the "1933 Act"), in reliance upon exemptions therefrom. Pursuant to the terms of the Securities and the Indenture, investors that acquire Securities may only resell or otherwise transfer such Securities if such Securities are hereafter registered under the 1933 Act or if an exemption from the registration requirements of the 1933 Act is available (including the exemption afforded by Rule 144A ("Rule 144A") of the rules and regulations promulgated under the 1933 Act by the Securities and Exchange Commission (the "Commission") (the "1933 Act Regulations")).

The Company has prepared and delivered to each Initial Purchaser copies of a preliminary offering memorandum dated December 5, 2001 (the "Preliminary Offering Memorandum") and has prepared and will deliver to each Initial Purchaser, on the date hereof or the next succeeding day, copies of a final offering memorandum dated January 9, 2002 (the "Final Offering Memorandum"), each for use by such Initial Purchaser in connection with its solicitation of purchases of, or offering of, the Securities. "Offering Memorandum" means, with respect to any date or time referred to in this

Agreement, the most recent offering memorandum (whether the Preliminary Offering Memorandum or the Final Offering Memorandum, or any amendment or supplement to either such document), including exhibits thereto and any documents incorporated therein by reference, which has been prepared and delivered by the Company to the Initial Purchasers in connection with their solicitation of purchases of, or offering of, the Securities.

All references in this Agreement to financial statements and schedules and other information which is "contained," "included" or "stated" in the Offering Memorandum (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is incorporated by reference in the Offering Memorandum; and all references in this Agreement to amendments or supplements to the Offering Memorandum shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934, as amended (the "1934 Act"), which is incorporated by reference in the Offering Memorandum.

(c) Denominations; Registration.

In such event or if during such time any event shall occur as a result of which it is necessary, in the reasonable opinion of any of the Company, its counsel, the Initial Purchasers or counsel for the Initial Purchasers, to amend or supplement the Offering Memorandum in order that the Offering Memorandum not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances then existing, the Company will forthwith amend or supplement the Offering

Memorandum by preparing and furnishing to each Initial Purchaser an amendment or amendments of, or a supplement or supplements to, the Offering Memorandum (in form and substance satisfactory in the reasonable opinion of counsel for the Initial Purchasers) so that, as so amended or supplemented, the Offering Memorandum will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at the time it is delivered to a Subsequent Purchaser, not misleading.

(c) Amendment to Offering Memorandum and Supplements. The Company will advise each Initial Purchaser promptly of any proposal to amend or supplement the Offering Memorandum and will not effect such amendment or supplement without the consent of the Initial Purchasers. Neither the consent of the Initial Purchasers, nor the Initial Purchaser's delivery of any such amendment or supplement, shall constitute a waiver of any of the conditions set forth in Section 5 hereof.

(d) Blue Sky Qualifications. The Company will endeavor, in cooperation with the Initial Purchasers, to qualify the Securities for offering and sale under the applicable securities laws of such states and other jurisdictions as the Representatives may designate and to maintain such qualifications in effect for a period of not less than one year from the date of the Offering Memorandum or such shorter period as is necessary to complete the distribution of the Securities; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject. In each jurisdiction in which the Securities have been so qualified, the Company will file such statements and reports as may be required by the laws of such jurisdiction to continue such qualification in effect for a period of not less than one year from the date of the Offering Memorandum. The Company will also supply the Initial Purchasers with such information as is necessary for the determination of the legality of the Securities for investment under the laws of such jurisdictions as the Initial Purchasers may request.

(e) Use of Proceeds. The Company will use the net proceeds received by it from the sale of the Securities in the manner specified in the Offering Memorandum under "Use of Proceeds".

During a period of 14 days from the date of the Offering Memorandum, the Company will not, without the prior written consent of Banc of America and ▇▇▇▇▇▇▇ ▇▇▇▇▇, directly or indirectly, issue, sell, offer or contract to sell, grant any option for the sale of, or otherwise transfer or dispose of, any debt securities of the Company other than such securities representing commercial bank debt or intercompany debt.

(a) Opinion of ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇, Esq.

(i) The Company has been duly incorporated and is an existing corporation in good standing under the laws of the State of Utah.

(ii) The Company has corporate power and authority to own its properties and conduct its business as described in the Offering Memorandum; and the Company is duly qualified to do business as a foreign corporation and is in good standing in all other jurisdictions in which it owns or leases substantial properties or in which the conduct of its business requires such qualification, except where the failure to be so qualified would not have a Material Adverse Effect.

(iii) The Securities are in the form contemplated by the Indenture, have been duly authorized by the Company and, assuming that the Securities have been duly authenticated by the Trustee in accordance with the terms of the Indenture, the Securities have been duly executed, issued and delivered by the Company and constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except to the extent that enforcement thereof may be limited by (a) bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or other similar laws now or hereinafter in effect relating to or affecting creditors' rights generally and (b) general principles of equity (regardless of whether enforceability is considered in a proceeding at law or in equity). In expressing the opinion set forth in this paragraph (iii), such counsel may assume that the Securities, in the form delivered to the Initial Purchasers, conform to the specimen of the Securities examined by such counsel, which fact need not be verified by an inspection of the individual Securities.

(iv) The execution, delivery and performance of the Indenture, of the Registration Rights Agreement and of this Agreement and the issuance and sale of the Securities and compliance with the terms and provisions hereof and thereof will not (a) result in a breach or violation of any of the terms or provisions of, or constitute a default under, (1) any law, rule, regulation or order known to such counsel of any governmental agency having jurisdiction over the Company or any of its properties or any agreement or instrument known to such counsel 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, which would cause a material adverse change in the financial position, shareholders' equity or results of operations of the Company or affect the validity of the Securities or the legal authority of the Company to comply with the terms of the Securities, the Indenture, this Agreement or (2) the charter or bylaws of the Company or (b) result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any subsidiary pursuant to any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or any other agreement or instrument, known to such counsel, to which the Company or any subsidiary is a party or by which it or any of them may be bound, or to which any of the property or assets of the Company or any subsidiary is subject (except for such liens, charges or encumbrances that would not have a

Material Adverse Effect); and the Company has full power and authority to authorize, issue and sell the Securities as contemplated by this Agreement.

(v) The Indenture has been duly authorized, executed and delivered by the Company and (assuming the due authorization, execution and delivery of the Indenture by the Trustee) is a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, except to the extent enforcement thereof may be limited by (a) bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or other similar laws now or hereinafter in effect relating to or affecting creditors' rights generally, and (b) general principles of equity (regardless of whether enforceability is considered in a proceeding at law or in equity).

(vi) Each of the Purchase Agreement and the Registration Rights Agreement has been duly authorized, executed and delivered by the Company and the Registration Rights Agreement constitutes a valid and legally binding agreement of the Company, enforceable against the Company in accordance with its terms.

(vii) No authorization, approval or consent of any governmental authority or agency is necessary in connection with the transactions contemplated by this Agreement, except such as may be required under state securities or Blue Sky laws, and except as have been obtained.

(ix) It is not necessary in connection with the offer, sale and delivery of the Securities to the Initial Purchasers and to each Subsequent Purchaser in the manner contemplated by the Purchase Agreement and the Offering Memorandum to register the Securities under the 1933 Act or to qualify the Indenture under the Trust Indenture Act.

(b) Opinion of Company Counsel.

(i) The Securities are in the form contemplated by the Indenture, and when executed and authenticated in accordance with the terms of the Indenture and delivered to and paid for by the Initial Purchasers in accordance with the terms hereof, will constitute valid and binding obligation of the Company, enforceable against the Company in accordance with their terms under the laws of the State of New York, except to the extent that enforcement thereof may be limited by (a) bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or other similar laws now or hereinafter in effect relating to or affecting creditors' rights generally and (b) general principles of equity (regardless of whether enforceability is considered in a proceeding at law or in equity).

(ii) The Securities and the Indenture conform in all material respects to the descriptions thereof contained in the Offering Memorandum.

(iii) The Indenture has been duly executed and delivered by the Company (to the extent such execution and delivery are matters governed by the laws of the State of New York) and (assuming the due authorization, execution and delivery of the Indenture by the Trustee) is a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms under the laws of the State of New York, except to the extent enforcement

thereof may be limited by (a) bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or other similar laws now or hereinafter in effect relating to or affecting creditors' rights generally and (b) general principles of equity (regardless of whether enforceability is considered in a proceeding at law or in equity).

(iv) Each of this Agreement and the Registration Rights Agreement has been duly executed and delivered by the Company (to the extent such execution and delivery are matters governed by the laws of the State of New York).

(v) Such counsel does not know of any legal or governmental proceedings which would be required to be disclosed in the Offering Memorandum which are not disclosed as required, assuming that the Offering Memorandum was subject to Regulation S-K of the 1933 Act Regulations.

(vi) No authorization, approval or consent of any governmental authority or agency is necessary in connection with the consummation by the Company of the transactions contemplated by this Agreement, except such as may be required by state securities or Blue Sky laws, and other than any that has been obtained.

(vii) The statements set forth in the Offering Memorandum under the captions "Description of the Notes" and "Exchange Offer and Registration Rights", insofar as such statements purport to summarize certain provisions of the documents referred to therein, fairly summarize such provisions in all material respects.

(viii) Assuming (i) the accuracy of the representations and warranties of the Company set forth in Section 1 of the Purchase Agreement, (ii) the due performance by the Company of the covenants and agreements set forth in Section 3 of the Purchase Agreement and the due performance by the Initial Purchasers of the covenants and agreements set forth in Section 6 of the Purchase Agreement, (iii) compliance by the Initial Purchasers with the offering and transfer procedures and restrictions described in the Offering Memorandum, (iv) the accuracy of the representations and warranties made in accordance with this Agreement and the Offering Memorandum by purchasers to whom the Initial Purchasers initially resell the Securities and (v) that purchasers to whom the Initial Purchasers initially resell the Securities receive a copy of the Offering Memorandum prior to such sale, the offer, sale and delivery of the Securities to the Initial Purchasers in the manner contemplated by the Purchase Agreement and the Offering Memorandum and the initial resale of the Securities by the Initial Purchasers in the manner contemplated in the Offering Memorandum and this Agreement, do not require registration under the Securities Act, and the Indenture does not require qualification under the Trust Indenture Act, it being understood that we do not express any opinion as to any subsequent resale of any Security.

(c) Opinion of Counsel to the Initial Purchasers. The opinion of Sidley ▇▇▇▇▇▇ ▇▇▇▇▇ & ▇▇▇▇ LLP, counsel to the Initial Purchasers, who may rely as to all matters governed by Utah law upon the opinion of ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇, Esq., referred to above, covering the matters referred to in subparagraph (a) under the subheading (i) and subparagraph (b) under the subheadings (i) through (iv), inclusive, (viii) and (ix) above.

(d) In giving their opinions as of the date hereof required by subsection (b), (c) and (d) of this Section, counsel (other than ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇) shall state that they have participated in conferences with officers and other representatives of the Company, representatives of the independent accountants of the Company, and the Initial Purchasers, at which the contents of the Offering Memorandum, and any amendments or supplements thereto, and related matters were discussed and although such counsel are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained in the Offering

Memorandum or any amendments or supplements thereto and have made no independent check or verification thereof, on the basis of the foregoing, no facts have come to such counsel's attention that lead them to believe that the Offering Memorandum, at the time the Offering Memorandum was issued, at the time any such amended or supplemented Offering Memorandum was issued or at the Closing Time, contained an 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. Such counsel may state that they express no opinion or belief with respect to the financial statements and the related notes, schedules and other financial or reserve data included in or excluded from the Offering Memorandum or the exhibits thereto or incorporated by reference in such Offering Memorandum.

(e) Officers' Certificate. At Closing Time, there shall not have been, since the date hereof or since the respective dates as of which information is given in the Offering Memorandum, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, and the Representatives shall have received a certificate of the President or a Vice President of the Company and of the chief financial or chief accounting officer of the Company, dated as of Closing Time, to the effect that (i) there has been no such material adverse change, (ii) the representations and warranties in Section 1(a) hereof are true and correct with the same force and effect as though expressly made at and as of Closing Time and (iii) the Company has complied with all covenants and agreements and satisfied all conditions on its part to be performed or satisfied at or prior to Closing Time.

(f) Accountants' Comfort Letter. At the time of the execution of this Agreement, the Representatives shall have received from Ernst & Young, LLP a letter dated such date, in form and substance satisfactory to the Representatives, together with signed or reproduced copies of such letter for each of the other Initial Purchasers containing statements and information of the type ordinarily included in accountants' "comfort letters" to underwriters with respect to the financial statements and certain financial information contained in the Offering Memorandum.

(g) Bring-down Comfort Letter. At Closing Time, the Representatives shall have received from Ernst & Young, LLP a letter, dated as of Closing Time, to the effect that they reaffirm the statements made in the letter furnished pursuant to subsection (f) of this Section, except that the specified date referred to shall be a date not more than three business days prior to Closing Time.

(h) Maintenance of Rating. At Closing Time, the Securities shall be rated at least Baa2 by ▇▇▇▇▇'▇ Investors Service Inc. and BBB+ by Standard & Poor's Ratings Services, a division of ▇▇▇▇▇▇-▇▇▇▇, Inc., and, if requested, the Company shall have delivered to the Representatives a letter dated the Closing Time, from each such rating agency, or other evidence satisfactory to the Representatives, confirming that the Securities have such ratings; and since the date of this Agreement, there shall not have occurred a downgrading in the rating assigned to the Securities or any of the Company's other debt securities by any "nationally recognized statistical rating agency", as that term is defined by the Commission for purposes of Rule 436(g)(2) under the 1933 Act, and no such organization shall have publicly announced that it has under surveillance or review its rating of the Securities or any of the Company's other debt securities.

(i) Additional Documents. At Closing Time, counsel for the Initial Purchasers shall have been furnished with such documents and opinions as they may reasonably require for the purpose of enabling them to pass upon the issuance and sale of the Securities as herein contemplated, or in order to evidence the accuracy of any of the representations or warranties, or the fulfillment of any of the conditions, herein contained; and all proceedings taken by the Company in connection with the issuance and sale of the Securities as herein contemplated shall be reasonably satisfactory in form and substance to the Representatives and counsel for the Initial Purchasers.

(j) Termination of Agreement. If any condition specified in this Section shall not have been fulfilled when and as required to be fulfilled, this Agreement may be terminated by the Representatives by notice to the Company at any time at or prior to Closing Time, and such termination shall be without liability of any party to any other party except as provided in Section 4 and except that Sections 1, 7, 8 and 9 shall survive any such termination and remain in full force and effect.

SECTION 6. Subsequent Offers and Resales of the Securities.

(a) Offer and Sale Procedures. Each of the Initial Purchasers and the Company hereby establish and agree to observe the following procedures in connection with the offer and sale of the Securities:

(i) Offers and Sales only to Qualified Institutional Buyers. Offers and sales of the Securities shall only be made to persons whom the offeror or seller reasonably believes to be qualified institutional buyers, as defined in Rule 144A under the 1933 Act ("Qualified Institutional Buyers").

(ii) No General Solicitation. No general solicitation or general advertising (within the meaning of Rule 502(c) under the ▇▇▇▇ ▇▇▇) will be used in the United States in connection with the offering or sale of the Securities.

(iii) Purchases by Non-Bank Fiduciaries. In the case of a non-bank Subsequent Purchaser of a Security acting as a fiduciary for one or more third parties, each third party shall, in the judgment of the applicable Initial Purchaser, be an Institutional Accredited Investor or a Qualified Institutional Buyer or a non-U.S. person outside the United States, as those terms are defined in Rule 144A.

(iv) Subsequent Purchaser Notification. Each Initial Purchaser will take reasonable steps to inform persons acquiring Securities from such Initial Purchaser that the Securities (A) have not been and will not be registered under the 1933 Act, (B) are being sold to them without registration under the 1933 Act in reliance on Rule 144A or in accordance with another exemption from registration under the 1933 Act, as the case may be, and (C) may not be offered, sold or otherwise transferred except (1) to the Company, or (2) in accordance with (x) Rule 144A to a person whom the seller reasonably believes is a Qualified Institutional Buyer that is purchasing such Securities for its own account or for the account of a Qualified Institutional Buyer to whom notice is given that the offer, sale or transfer is being made in reliance on Rule 144A or (y) pursuant to another available exemption from registration under the 1933 Act.

(v) Restrictions on Transfer. The transfer restrictions and the other provisions set forth in the Offering Memorandum under the heading "Notice to Investors", including the legend required thereby, shall apply to the Securities except as otherwise agreed by the Company and the Initial Purchasers.

(vi) Delivery of Offering Memorandum. Each Initial Purchaser will deliver to each purchaser of the Securities from such Initial Purchaser, in connection with its original distribution of the Securities, a copy of the Offering Memorandum, as amended and supplemented at the date of such delivery.

(b) Covenants of the Company. The Company covenants with each Initial Purchaser as follows:

(i) Integration. The Company agrees that it will not and will cause its Affiliates not to, directly or indirectly, solicit any offer to buy, sell or make any offer or sale of, or otherwise negotiate in respect of, securities of the Company of any class if, as a result of the doctrine of

"integration" referred to in Rule 502 under the 1933 Act, such offer or sale would render invalid (for the purpose of (A) the sale of the offered Securities by the Company to the Initial Purchasers, (B) the resale of the offered Securities by the Initial Purchasers to Subsequent Purchasers or (C) the resale of the offered Securities by such Subsequent Purchasers to others) the exemption from the registration requirements of the 1933 Act provided by Section 4(2) thereof or by Rule 144A thereunder or otherwise.

(ii) Rule 144A Information. The Company agrees that, in order to render the offered Securities eligible for resale pursuant to Rule 144A under the 1933 Act, while any of the offered Securities remain outstanding, it will make available, upon request, to any holder of offered Securities or prospective purchasers of Securities the information specified in Rule 144A(d)(4), unless the Company furnishes information to the Commission pursuant to Section 13 or 15(d) of the 1934 Act.

(iii) Restriction on Resales. Until the expiration of two years after the original issuance of the offered securities, the Company will not, and will cause its Affiliates not to, resell any offered Securities which are "restricted securities" (as such term is defined under Rule 144(a)(3) under the 1933 Act), whether as beneficial owner or otherwise (except as agent acting as a securities broker on behalf of and for the account of customers in the ordinary course of business in unsolicited broker's transactions).

(c) Qualified Institutional Buyer. Each Initial Purchaser severally and not jointly represents and warrants to, and agrees with, the Company that it is a Qualified Institutional Buyer and an "accredited investor" within the meaning of Rule 501(a) under the 1933 Act (an "Accredited Investor").

SECTION 7. Indemnification.

(a) Indemnification of Initial Purchasers. The Company agrees to indemnify and hold harmless each Initial Purchaser and each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Offering Memorandum or the Final Offering Memorandum (or any amendment thereto) or the omission or alleged omission therefrom of a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 7(d) below) any such settlement is effected with the written consent of the Company; and

(iii) against any and all expense whatsoever, as incurred (including, subject to Section 7(c) hereof, the fees and disbursements of counsel chosen by Banc of America), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue

statement or omission made in reliance upon and in conformity with written information furnished to the Company or special counsel to the Company by any Initial Purchaser expressly for use in the Offering Memorandum (or any amendment or supplement thereto). The foregoing indemnity with respect to any untrue statement contained in or omitted from a Preliminary Offering Memorandum shall not inure to the benefit of any Initial Purchaser (or any person controlling such Initial Purchaser) from whom the person asserting any such loss, liability, claim, damage or expense purchased any of the Securities which are the subject thereof if such person did not receive a copy of the Final Offering Memorandum (or any amendment or supplement thereto) (in each case exclusive of the documents from which information is incorporated by reference) at or prior to the written confirmation of the sale of such Securities to such person and the untrue statement contained in or omitted from such Preliminary Offering Memorandum was corrected in the Final Offering Memorandum (or any amendment or supplement thereto) and provided that the Company has satisfied its obligations pursuant to Section 3(a) of this Agreement to provide the Initial Purchasers with a sufficient number of copies of any amendment or supplement to the Offering Memorandum in a timely manner.

(b) Indemnification of Company. Each Initial Purchaser, severally and not jointly, agrees to indemnify and hold harmless the Company and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Offering Memorandum (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company or special counsel to the Company by such Initial Purchaser expressly for use in the Offering Memorandum (or any amendment or supplement thereto), and will reimburse any legal or other expenses reasonably incurred by the Company in connection with investigating or defending such loss, liability, claim, damage, expense or action as such expenses are incurred.

(c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 7(a) above, counsel to the indemnified parties shall be selected by Banc of America and ▇▇▇▇▇▇▇ ▇▇▇▇▇, and, in the case of parties indemnified pursuant to Section 7(b) above, counsel to the indemnified parties shall be selected by the Company. If it so elects within a reasonable time after receipt of such notice, an indemnifying party, jointly with any other indemnifying parties receiving such notice, may assume the defense of such action with counsel chosen by it and approved by the indemnified parties defendant in such action (which approval shall not be unreasonably withheld), unless such indemnified parties reasonably object to such assumption on the ground that there may be legal defenses available to them which are different from or in addition to those available to such indemnifying party. If an indemnifying party assumes the defense of such action, the indemnifying party shall not be liable for any fees and expenses of counsel for the indemnified parties incurred thereafter in connection with such action other than the reasonable costs of investigation. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all 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. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened,

or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 7 or Section 8 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding 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.

(d) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the 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)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (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 prior to the date of such settlement. Notwithstanding the immediately preceding sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, an indemnifying party shall not be liable for any settlement of the nature contemplated by Section 7(a)(ii) effected without its consent if such indemnifying party (i) reimburses such indemnified party in accordance with such request to the extent it considers such request to be reasonable and (ii) provides written notice to the indemnified party substantiating the unpaid balance as unreasonable, in each case prior to the date of such settlement.

SECTION 8. Contribution. If the indemnification provided for in Section 7 hereof is for any reason (except as provided therein) unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Initial Purchasers on the other hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) 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 of the Initial Purchasers on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company on the one hand and the Initial Purchasers on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company and the total purchase discount received by the Initial Purchasers, in each case as set forth on the cover of the Offering Memorandum, bear to the aggregate initial offering price of the Securities as set forth on such cover.

The relative fault of the Company on the one hand and the Initial Purchasers on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Initial Purchasers and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 8. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 8 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 8, no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the total price at which the Securities purchased by it and distributed to the subsequent purchaser were offered to the subsequent purchaser exceeds the amount of any damages which such Initial Purchaser has otherwise been required to pay by reason of any 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 ▇▇▇▇ ▇▇▇) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 8, each person, if any, who controls an Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Initial Purchaser, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Initial Purchasers' respective obligations to contribute pursuant to this Section are several in proportion to the principal amount of Securities set forth opposite their respective names in Schedule A hereto and not joint.

SECTION 9. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Initial Purchaser or controlling person, or by or on behalf of the Company, and shall survive delivery of the Securities to the Initial Purchasers.

SECTION 10. Termination of Agreement.

(a) Termination; General. The Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Offering Memorandum, any material adverse change in the condition, financial or otherwise, or in

the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or any outbreak of hostilities or escalation thereof or other calamity or crisis, in each case the effect of which is such as to make it, in the reasonable judgment of the Representatives, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in the Securities has been suspended or materially limited by the Commission, or if trading generally on the American Stock Exchange or the New York Stock Exchange or in the Nasdaq National Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of the exchanges or by such system or by order of the Commission, the National Association of Securities Dealers, Inc. or any other governmental authority, or a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or (iv) if a banking moratorium has been declared by either Federal, New York or Utah authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party (except as provided in Section 4 hereof, and provided further that Sections 1, 7, 8 and 9 shall survive such termination and remain in full force and effect, pursuant to a termination under Section 10(a)(i)).

SECTION 11. Default by One or More of the Initial Purchasers. If one or more of the Initial Purchasers shall fail at Closing Time to purchase the Securities which it or they are obligated to purchase under this Agreement (the "Defaulted Securities"), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Initial Purchasers, or any other initial purchasers, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(a) if the number of Defaulted Securities does not exceed 10% of the aggregate principal amount of the Securities to be purchased hereunder, each of the non-defaulting Initial Purchasers shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective purchase obligations hereunder bear to the purchase obligations of all non-defaulting Initial Purchasers, or

(b) if the number of Defaulted Securities exceeds 10% of the aggregate principal amount of the Securities to be purchased hereunder, this Agreement shall terminate without liability on the part of any non-defaulting Initial Purchaser.

No action taken pursuant to this Section 11 shall relieve any defaulting Initial Purchaser from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, either the Representatives or the Company shall have the right to postpone the Closing Time for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used herein, the term "Initial Purchaser" includes any person substituted for an Initial Purchaser under this Section 11.

SECTION 12. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Initial Purchasers shall be directed to the Representatives at the offices of Banc of America, Banc of America Corporate Center, ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇, attention: Transaction Management, and ▇▇▇▇▇▇▇ ▇▇▇▇▇, Four World Financial Center, New York, New York 10008, attention: ▇▇▇▇▇ ▇▇▇▇▇▇▇▇; and notices to the Company shall be

directed to it at ▇▇▇ ▇▇▇▇ ▇▇▇ ▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇ ▇▇▇▇, ▇▇, ▇▇▇▇▇, attention of ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇, Vice President, Treasurer and Chief Financial Officer.

SECTION 13. Parties. This Agreement shall each inure to the benefit of and be binding upon the Initial Purchasers and the Company and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Initial Purchasers and the Company and their respective successors and the controlling persons referred to in Sections 7 and 8 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Initial Purchasers and the Company and their respective successors, and the controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any Initial Purchaser shall be deemed to be a successor by reason merely of such purchase.

SECTION 14. GOVERNING LAW AND TIME. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

SECTION 15. Effect of Headings. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company a counterpart hereof, whereupon this instrument, along with all counterparts, will become a binding agreement among the Initial Purchasers and the Company in accordance with its terms.
