(f) The Indenture has been duly qualified under the Trust Indenture Act and has been duly authorized, executed and delivered by the Company and is a valid and binding agreement of the Company, enforceable in accordance with its terms except as (i) the enforceability thereof may be limited by bankruptcy, insolvency or similar laws affecting creditors' rights generally and (ii) rights of acceleration and the availability of equitable remedies may be limited by equitable principles of general applicability.

(l) The Company is not an "INVESTMENT COMPANY" or an entity "CONTROLLED" by an "INVESTMENT COMPANY," as such terms are defined in the Investment Company Act of 1940, as amended.

2. Delayed Delivery Contracts. If the Prospectus provides for sales of Offered Securities pursuant to Delayed Delivery Contracts, the Company hereby authorizes the Underwriters to solicit offers to purchase Contract Securities on the terms and subject to the conditions set forth in the Prospectus pursuant to Delayed Delivery Contracts. Delayed Delivery Contracts may be entered into only with institutional investors approved by the Company of the types set forth in the Prospectus. On the

Closing Date, the Company will pay to the Manager as compensation for the accounts of the Underwriters the commission set forth in the Underwriting Agreement in respect of the Contract Securities. The Underwriters will not have any responsibility in respect of the validity or the performance of any Delayed Delivery Contracts.

If the Company executes and delivers Delayed Delivery Contracts with institutional investors, the aggregate amount of Offered Securities to be purchased by the several Underwriters shall be reduced by the aggregate amount of Contract Securities; such reduction shall be applied to the commitment of each Underwriter pro rata in proportion to the amount of Offered Securities set forth opposite such Underwriter's name in the Underwriting Agreement, except to the extent that the Manager determines that such reduction shall be applied in other proportions and so advises the Company; provided, however, that the total amount of Offered Securities to be purchased by all Underwriters shall be the aggregate amount set forth above, less the aggregate amount of Contract Securities.

3. Public Offering. The Company is advised by the Manager that the Underwriters propose to make a public offering of their respective portions of the Underwriters' Securities as soon after this Agreement has been entered into as in the Manager's judgment is advisable. The terms of the public offering of the Underwriters' Securities are set forth in the Prospectus.

4. Purchase and Delivery. Except as otherwise provided (i) in this
Section 4, payment for the Underwriters' Securities shall be made in immediately available funds at the time and place set forth in the Underwriting Agreement, upon delivery to the Manager for the respective accounts of the several Underwriters of the Underwriters' Securities, registered in such names and in such denominations as the Manager shall request prior to the date of delivery, with any transfer taxes payable in connection with the transfer of the Underwriters' Securities to the Underwriters duly paid.

Delivery on the Closing Date of any Underwriters' Securities that are Debt Securities in bearer form shall be effected by delivery of a single temporary global Debt Security without coupons (the "GLOBAL DEBT SECURITY") evidencing the Offered Securities that are Debt Securities in bearer form to a common depositary for Euroclear Bank, S.A./N.V., as operator of the Euroclear System ("EUROCLEAR"), and for Clearstream Banking S.A. ("CLEARSTREAM") for credit to the respective accounts at Euroclear or Clearstream of each Underwriter or to such other accounts as such Underwriter may direct. Any Global Debt Security shall be delivered to the Manager not later than the Closing Date, against payment of funds to the Company in the net amount due to the Company for such Global Debt Security, by the method and in the form set forth in the Underwriting Agreement. The Company shall cause definitive Debt Securities in bearer form to be prepared and delivered in exchange for such Global Debt Security in such manner and at such time as may be provided in or pursuant to the Indenture; provided,

however, that the Global Debt Security shall be exchangeable for definitive Debt Securities in bearer form only on or after the date specified for such purpose in the Prospectus.

5. Conditions to Closing. The several obligations of the Underwriters hereunder are subject to the following conditions:

(a) Subsequent to the execution and delivery of the Underwriting Agreement and prior to the Closing Date,

(i) there shall not have occurred any downgrading, nor shall any official notice have been given of any intended or potential downgrading or of any review for a possible change that does not indicate the direction of the possible change, in the rating accorded any of the Company's securities by Moody's Investors Service Inc., Standard & Poor's Corporation or Duff & Phelps Inc.;

(ii) there shall not have occurred any change, or any development involving a prospective change, in the condition, financial or otherwise, or in the earnings, business or operations, of the Company and its subsidiaries, taken as a whole, from that set forth in the Prospectus, that, in the reasonable judgment of the Manager, is material and adverse and that makes it, in the reasonable judgment of the Manager, impracticable to market the Offered Securities on the terms and in the manner contemplated in the Prospectus; and

(iii) no stop order suspending the effectiveness of Registration Statement shall have been issued.

(b) The Manager shall have received on the Closing Date a certificate, dated the Closing Date and signed by an executive officer of the Company, to the effect set forth in clause (a)(i) above and to the effect that the representations and warranties of the Company contained in this Agreement are true and correct as of the Closing Date and that the Company has complied with all of the agreements and satisfied all of the conditions on its part to be performed or satisfied on or before the Closing Date.

The officer signing and delivering such certificate may rely upon the best of his knowledge as to proceedings threatened.

(c) The Manager shall have received on the Closing Date an opinion of S. David Colton, Senior Vice President and General Counsel of the Company, dated the Closing Date, to the effect set forth in Exhibit A.

(d) The Manager shall have received on the Closing Date an opinion of Debevoise & Plimpton, counsel for the Company, dated the Closing Date, to the effect set forth in Exhibit B.

(g) On the Closing Date special counsel for the Underwriters shall have been furnished with such documents and opinions as they may require for the purpose of enabling them to pass upon the issuance and sale of the Offered 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.

6. Covenants of the Company. In further consideration of the agreements of the Underwriters contained herein, the Company covenants as follows:

(b) Before amending or supplementing the Registration Statement or the Prospectus with respect to the Offered Securities, to furnish to the Manager a copy of each such proposed amendment or supplement and not to file any such proposed amendment or supplement to which the Manager reasonably objects. The Company will cause the Prospectus Supplement to be filed with the Commission pursuant to Rule 424 under the Securities Act.

(c) If, during such period after the first date of the public offering of the Offered Securities as in the reasonable opinion of counsel for the Underwriters the Prospectus is required by law to be delivered in connection with sales by an

Underwriter or dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus is delivered to a purchaser, not misleading, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Prospectus to comply with law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters, and to the dealers (whose names and addresses the Manager will furnish to the Company) to which Offered Securities may have been sold by the Manager on behalf of the Underwriters and to any other dealer upon request, either amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus, as so amended or supplemented, will comply with law.

(d) To endeavor to qualify the Offered Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Manager shall reasonably request and to pay all expenses (including fees and disbursements of counsel) in connection with such qualification and in connection with (i) the determination of the eligibility of the Offered Securities for investment under the laws of such jurisdictions as the Manager may designate and (ii) any review of the offering of the Offered Securities by the National Association of Securities Dealers, Inc.; provided, however, the Company shall not be obligated to qualify as a foreign corporation or file any general consent to service of process under the laws of any such jurisdiction or subject itself to taxation as doing business in any such jurisdiction.

(e) To make generally available to the Company's security holders and to the Manager as soon as practicable an earning statement covering a twelve month period beginning on the first day of the first full fiscal quarter after the date of this Agreement, which earning statement shall satisfy the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder, including Rule 158 thereunder.

(f) During the period beginning on the date of the Underwriting Agreement and continuing to and including the Closing Date, not to offer, sell, contract to sell or otherwise dispose of any debt securities of the Company or warrants to purchase debt securities of the Company substantially similar to the Offered Securities (other than (i) the Offered Securities, (ii) commercial paper issued in the ordinary course of business and (iii) bank borrowings), without the prior written consent of the Manager.

(c) if it is a United States person, it is acquiring the Debt Securities in bearer form for purposes of resale in connection with their original issuance and if it retains Debt Securities in bearer form for its own account, it will only do so in accordance with the requirements of U.S. Treas. Reg. Section 1.163-5(c)(2)(i)(D)(6);

All other terms used in the preceding paragraph have the meaning given to them by the U.S. Internal Revenue Code (the "CODE") and regulations thereunder, including the D Rules. The restricted period is defined at U.S. Treas. Reg. Section 1.163-5(c)(2)(i)(D)(7).

8. Indemnification and Contribution. The Company agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls such Underwriter within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred by any Underwriter or any such controlling person in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus or the Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Manager expressly for use therein.

Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to such Underwriter, but only with reference to information relating to such Underwriter furnished to the Company by such Underwriter in writing through the Manager expressly for use in the Registration Statement, any preliminary prospectus, the Prospectus or any amendments or supplements thereto.

In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to either of the two preceding paragraphs, such person (the "INDEMNIFIED PARTY") shall promptly notify the person against whom such indemnity may be sought (the

"INDEMNIFYING PARTY") in writing; provided that the failure to so notify the indemnifying party will not relieve the indemnifying party from any liability under the two preceding paragraphs to the extent the indemnifying party is not materially prejudiced as a result thereof. The indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Manager, in the case of parties indemnified pursuant to the second preceding paragraph, and by the Company, in the case of parties indemnified pursuant to the first preceding paragraph. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing 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 as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

If the indemnification provided for in the first or second paragraph in this Section 8 is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to

the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Offered 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 of the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Offered Securities shall be deemed to be in the same respective proportions as the net proceeds from the offering of such Offered Securities (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus Supplement, bear to the aggregate public offering price of the Offered Securities. The relative fault of the Company on the one hand and of the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters' respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective principal amounts of Offered Securities purchased by each of such Underwriters and not joint.

The Company and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, 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 Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Offered Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this
Section 8 are not exclusive and

shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

The indemnity and contribution provisions contained in this Section 8 and the representations and warranties of the Company contained herein shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter or by or on behalf of the Company, its directors or officers or any person controlling the Company and
(iii) acceptance of and payment for any of the Offered Securities.

9. Termination. This Agreement shall be subject to termination, by notice given by the Manager to the Company, if (a) after the execution and delivery of the Underwriting Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on or by, as the case may be, any of the New York Stock Exchange, the American Stock Exchange, the National Association of Securities Dealers, Inc., the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a general moratorium on commercial banking activities in New York shall have been declared by either Federal or New York State authorities, or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis that, in the reasonable judgment of the Manager, is material and adverse and (b) in the case of any of the events specified in clauses (a)(i) through (iv), such event, singly or together with any other such event, makes it, in the reasonable judgment of the Manager, impracticable to market the Offered Securities on the terms and in the manner contemplated in the Prospectus.

10. Defaulting Underwriters. If, on the Closing Date, any one or more of the Underwriters shall fail or refuse to purchase Underwriters' Securities that it has or they have agreed to purchase hereunder on such date, and the aggregate amount of Underwriters' Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate amount of the Underwriters' Securities to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the amount of Underwriters' Securities set forth opposite their respective names above bears to the aggregate amount of Underwriters' Securities set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Manager may specify, to purchase the Underwriters' Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the amount of Underwriters' Securities that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 10 by an amount in excess of one-ninth of such amount of Underwriters' Securities without the written consent of such

Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Underwriters' Securities and the aggregate amount of Underwriters' Securities with respect to which such default occurs is more than one-tenth of the aggregate amount of Underwriters' Securities to be purchased on such date, and arrangements satisfactory to the Manager and the Company for the purchase of such Underwriters' Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company. In any such case either the Manager or the Company shall have the right to postpone the Closing Date but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and in the Prospectus or in any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering of the Offered Securities.

11. Miscellaneous. The Underwriting Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

12. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

Exhibit A

Opinion of General Counsel
for the Company

The opinion of General Counsel for the Company, to be delivered pursuant to Section 5(c) of the Underwriting Agreement shall be to the effect that:

1. The statements (1) in "ITEM 3 - LEGAL PROCEEDINGS" of the Company's most recent annual report on Form 10-K incorporated by reference in the Prospectus and (2) in "ITEM 1 - LEGAL PROCEEDINGS" of Part II of the Company's quarterly reports on Form 10-Q, if any, filed since such annual report, in each case insofar as such statements constitute summaries of the legal matters, documents or proceedings referred to therein, fairly present the information called for under the Exchange Act with respect to such legal matters, documents and proceedings.

2. To the best of my knowledge, the execution and delivery by the Company of, and the performance by the Company of its obligations under, the Underwriting Agreement, the Indenture, the Offered Securities and the Delayed Delivery Contracts will not contravene any provision of any agreement or other instrument binding upon the Company or any of its subsidiaries that is material to the Company and its subsidiaries, taken as a whole.

3. To the best of my knowledge, I do not know of any legal or governmental proceedings pending or threatened to which the Company or any of its subsidiaries is a party or to which any of the properties of the Company or any of its subsidiaries is subject that are required to be described in the Registration Statement or the Prospectus and are not so described or of any contracts or other documents that are required to be described in the Registration Statement or the Prospectus or to be filed as exhibits to the Registration Statement that are not described or filed as required.

I am delivering this opinion to you pursuant to Section 5(c) of the Underwriting Agreement, and no persons other than the several Underwriters are entitled to rely on this opinion.

The opinions expressed herein are limited to the Federal laws of the United States and the laws of the State of Arizona.

Exhibit B

Opinion of Debevoise & Plimpton,
Counsel for the Company

The opinion of Debevoise & Plimpton, independent counsel for the Company, to be delivered pursuant to Section 5(d) of the Underwriting Agreement shall be to the effect that:

1. The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of New York, with full corporate power and authority under such laws to own its properties and conduct its business as described in the Prospectus, and is duly qualified to transact business as a foreign corporation and is in good standing under the laws of the States of Arizona and New Mexico.

2. The Underwriting Agreement has been duly authorized, executed and delivered by the Company.

3. The Indenture has been duly qualified under the Trust Indenture Act and has been duly authorized, executed and delivered by the Company and is a valid and binding agreement of the Company, enforceable in accordance with its terms except that such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium and similar laws of general application affecting the rights and remedies of creditors and by general equitable principles.

4. The Delayed Delivery Contracts have been duly authorized, executed and delivered by the Company and are valid and binding agreements of the Company, enforceable in accordance with their respective terms except that such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium and similar laws of general application affecting the rights and remedies of creditors and by general equitable principles.

5. The Offered Securities have been duly authorized and, when executed and authenticated in accordance with the provisions of the Indenture and delivered to and paid for by the Underwriters in accordance with the terms of the Underwriting Agreement, in the case of Underwriters' Securities, or by institutional investors in accordance with the terms of the Delayed Delivery Contracts, in the case of the Contract Securities, will be entitled to the benefits of the Indenture and will be valid and binding obligations of the Company enforceable in accordance with their respective terms except that such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium and similar law of general application affecting the rights and remedies of creditors and by general equitable principles.

6. The execution and delivery by the Company of, and the performance by the Company of its obligations under, the Underwriting Agreement, the Indenture, the Offered Securities and the Delayed Delivery Contracts will not contravene any provision of applicable law or the Certificate of Incorporation or By-Laws of the Company or, to the best of our knowledge, any judgment, order or decree of any governmental body, agency or court having jurisdiction over the Company. To the best of our knowledge, no consent, approval, authorization or order of or qualification with any governmental body or agency is required for the performance by the Company of its obligations under the Underwriting Agreement, the Indenture, the Offered Securities and the Delayed Delivery Contracts, other than the order of the Securities and Exchange Commission making the Registration Statement effective under the Securities Act and qualifying the Indenture under the Trust Indenture Act of 1939, as amended, and except such as may be required by the securities or Blue Sky laws of the various states in connection with the offer and sale of the Offered Securities.

7. The statements (a) in the Prospectus under the captions "DESCRIPTIONS OF THE DEBT SECURITIES", "PLAN OF DISTRIBUTION" and "DESCRIPTION OF THE NOTES" and (b) in the Registration Statement under Item 15, in each case insofar as such statements constitute summaries of the legal matters, documents or proceedings referred to therein, fairly present the information called for under the Securities Act with respect to such legal matters, documents and proceedings.

8. The Company is not an "INVESTMENT COMPANY" or an entity "CONTROLLED" by an "INVESTMENT COMPANY", as such terms are defined in the Investment Company Act of 1940, as amended.

9. The Registration Statement and Prospectus (except for the financial statements and other financial and statistical information and schedules included therein or incorporated by reference as to which we express no opinion) appear on their face to be appropriately responsive in all material respects with the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder.

10. Each document, if any, filed pursuant to the Exchange Act and incorporated by reference in the Prospectus (except for financial statements and other financial and statistical information and schedules included therein or incorporated by reference as to which we express no opinion) appears on its face to be appropriately responsive in all material respects with the Exchange Act and the applicable rules and regulations of the Commission thereunder.

We have not ourselves checked the accuracy and completeness of, or otherwise verified, and are not passing upon and assume no responsibility for the accuracy or completeness of, the statements contained in the Registration Statement or the Prospectus except to the limited extent stated in paragraphs 7 and 9 above. In the course of our

review and discussion of the contents of the Registration Statement and the Prospectus with certain officers and employees of the Company and its independent accountants, but without independent check or verification, no facts have come to our attention which cause us to believe that the Registration Statement (other than the financial statements and other financial and statistical information contained therein or incorporated by reference or the part of the Registration Statement that constitutes the Form T-1, as to which we express no belief) at the time it became effective contained, or as of the date hereof contains, an untrue statement of a material fact or omitted, or as of the date hereof omits, to state a material fact required to be stated therein or necessary to make the statements contained therein not misleading, or that the Prospectus (other than the financial statements and other financial and statistical information contained therein or incorporated by reference as to which we express no belief) contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

We are delivering this opinion to you pursuant to section 5(d) of the Underwriting Agreement, and no persons other than the several Underwriters are entitled to rely on this opinion.

The opinions expressed herein are limited to the Federal laws of the United States and the laws of the State of New York.

(ii) the execution and delivery of the Indenture have been duly authorized by all necessary corporate action of the Company, and the Indenture has been duly executed and delivered by the Company, has been duly qualified under the Trust Indenture Act of 1939, as amended, and is a valid, binding and enforceable agreement of the Company, subject to applicable bankruptcy, insolvency and similar laws affecting creditors' rights generally and to general principles of equity.

(v) the statements in the Prospectus under the captions "DESCRIPTION OF THE DEBT SECURITIES", "DESCRIPTION OF THE NOTES" and "PLAN OF DISTRIBUTION," insofar as such statements purport to summarize certain provisions of the Offered Securities and the offering thereof, provide a fair summary of such provisions; and

(vi) no information has come to the attention of such counsel that causes it to (1) believe that the Registration Statement, including the documents incorporated by reference therein (except the financial statements and Schedules and other financial and statistical data included therein, as to which such counsel need not express any belief and except for that part of the Registration Statement that constitutes the Form T-1 heretofore referred to), at the time it became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading and
(2) believes that the Prospectus, including the documents incorporated by reference therein (except the financial statements and Schedules and other financial and statistical data included therein, as to which such counsel need not express any belief), as of the date thereof or of the date such opinion is delivered, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(vii) With respect to clause (vi) above, such counsel may provide such statements in a separate letter, and may state that their opinion and belief are based upon their participation in the preparation of the Registration Statement and the Prospectus and any amendments or supplements thereto (other than the documents incorporated by reference) and upon review and discussion of the contents thereof (including portions of certain of the documents incorporated by reference) but are without independent check or verification, except as specified.

Schedule I

DELAYED DELIVERY CONTRACT

___________, 200

Dear Sirs:

The undersigned hereby agrees to purchase from Phelps Dodge Corporation, a New York corporation (the "COMPANY"), and the Company agrees to sell to the undersigned the Company's securities described in Schedule A annexed hereto (the "SECURITIES"), offered by the Company's Prospectus dated January 18, 2001 and Prospectus Supplement dated ________________, 2001, receipt of copies of which are hereby acknowledged, at a purchase price stated in Schedule A and on the further terms and conditions set forth in this Agreement. The undersigned does not contemplate selling Securities prior to making payment therefor.

The undersigned will purchase from the Company Securities in the principal amount and numbers on the delivery dates set forth in Schedule A. Each such date on which Securities are to be purchased hereunder is hereinafter referred to as a "DELIVERY DATE."

Payment for the Securities which the undersigned has agreed to purchase on each Delivery Date shall be made to the Company or its order by certified or official bank check in New York Clearing House funds at the office of _______________________, New York, N.Y., at 10:00 a.m. (New York time) on the Delivery Date, upon delivery to the undersigned of the Securities to be purchased by the undersigned on the Delivery Date, in such denominations and registered in such names as the undersigned may designate by written or telegraphic communication addressed to the Company not less than five full business days prior to the Delivery Date.

The obligation of the undersigned to take delivery of and make payment for the Securities on the Delivery Date shall be subject to the conditions that
(1) the purchase of Securities to be made by the undersigned shall not at the time of delivery be prohibited under the laws of the jurisdiction to which the undersigned is subject and (2) the Company shall have sold, and delivery shall have taken place to the underwriters (the "UNDERWRITERS") named in the Prospectus Supplement referred to above of, such part of the Securities as is to be sold to them. Promptly after completion of sale and delivery to the Underwriters, the Company will mail or deliver to the undersigned as its address set forth below notice to such effect, accompanied by a copy of the opinion of counsel for the Company delivered to the Underwriters in connection therewith.

If this Agreement is acceptable to the Company, it is requested that the Company sign the form of acceptance below and mail or deliver one of the counterparts hereof to the undersigned at its address set forth below.
