CONDITIONS TO THE OBLIGATIONS OF THE INITIAL PURCHASERS. The obligations of the Initial Purchasers to purchase the Securities shall be subject to the accuracy of the representations and warranties on the part of the Company contained herein at the date and time that this Agreement is executed and delivered by the parties hereto (the "Execution Time") and the Closing Time, to the accuracy of the statements of the Company made in any certificates pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions: (a) OPINION OF COUNSEL FOR COMPANY. At the Closing Time, the Initial Purchasers shall have received the favorable opinions, dated as of the Closing Date, of Willkie Farr & Gallagher, counsel for the Company, and of the General Counsel or Securities Counsel of the Company, in form and substance satisfactory to counsel for the Initial Purchasers, to the effect set forth in Exhibits A-1 and A-2 hereto, respectively, and to such further effect as counsel to the Initial Purchasers may reasonably request; (b) OPINION OF COUNSEL FOR INITIAL PURCHASERS. At the Closing Time, the Initial Purchasers shall have received the favorable opinion, dated as of the Closing Date, of Sullivan & Cromwell, counsel for the Initial Purchasers, with respect to the incorporation of the Company, the Indentures, the validity of the Securities being delivered at the Closing Time, the Offering Circular and such other related matters as the Initial Purchasers may reasonably request. In giving such opinion such counsel may rely, as to all matters governed by the laws of jurisdictions other than the law of the State of New York and the federal law of the United States, upon the opinions of counsel satisfactory to the Initial Purchasers. Such counsel may also state that, insofar as such opinion involves factual matters, they have relied, to the extent they deem proper, upon certificates of officers of the Company and its subsidiaries and certificates of public officials; (c) OFFICERS' CERTIFICATE. At such Closing Time, there shall not have been, since the Execution Date or since the date of the most recent financial statements included in the Offering Circular (exclusive of any supplement thereto), 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 from transactions in the ordinary course of business except as set forth in the Offering Circular (exclusive of any supplement thereto), and the Initial Purchasers shall have received certificates of the Chairman of the Board, the President or a Vice President of the Company and of the chief financial or chief accounting officer of the Company, satisfactory to the Initial Purchasers, to the effect that, at and as of such Closing 13 Time, (i) they have carefully examined the Offering Circular and any supplements thereto and this Agreement, (ii) there has been no such material adverse change, (iii) the representations and warranties of the Company in Section 1 hereof are true and correct in all material respects at and as of the Closing Time with the same force and effect as though expressly made at and as of such Closing Time, and (iv) the Company has complied with all agreements and satisfied all conditions on its part to be performed or satisfied at or prior to such Closing Time; (d) ACCOUNTANT'S COMFORT LETTER.

At the Closing Date, the Securities shall be rated at least B by Standard & Poor's Corporation and B3 by Moody's Investors Service Inc. and, on or after the Execution Date, there shall not have occurred a downgrading in the rating assigned to the Company's debt securities or preferred stock by any "nationally recognized statistical rating organization," as that term is defined by the Commission for purposes of Rule 436(g)(2) under the Act, and no such organization shall have publicly announced that it has under surveillance or review its rating of any of the Company's debt securities or preferred stock; (g) OFFERING CIRCULAR. The Offering Circular shall be in form and substance reasonably satisfactory to the Initial Purchasers. The Company shall have complied with the provisions of Section 4(a) hereof with respect to the furnishing of Offering Circulars as soon as practicable but in no event later than 2:00 p.m. on November 16, 1999; (h) ADEQUATE DISCLOSURE OF LITIGATION. There is no litigation or governmental or other action, suit, claim, proceeding or investigation before any court or any public, regulatory or governmental agency or body, pending or, to the best of the Company's knowledge, threatened against the Company or any of its subsidiaries or any of their respective officers (in their capacity as officers of the Company or such subsidiaries) or any of the properties, assets, business or rights 14 of the Company or such subsidiaries which is of a character required to be disclosed in the Offering Circular which is not disclosed therein; (i) ADDITIONAL DOCUMENTS. At the Closing Time: (i) the Company shall have furnished to the Initial Purchasers such further information, certificates and documents as the Initial Purchasers may reasonably request; (ii) counsel for the Initial Purchasers 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 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 (iii) all proceedings taken by the Company in connection with the issuance and sale of the Securities as herein contemplated shall be satisfactory in form and substance to the Initial Purchasers and counsel for the Initial Purchasers; (j) COMMITMENT LETTER CONSENTS. The financial institutions signatory to the Commitment Letter shall have consented to the execution, delivery and performance of this Agreement and the transactions contemplated hereby, and the Company shall have furnished to the Initial Purchasers evidence of such consent satisfactory to the Initial Purchasers (such consent also being a condition to the obligations of the Company hereunder); and (k) 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 Initial Purchasers by notice to the Company at any time at or prior to the Closing Time, and such termination shall be without liability of any party to any other party except as provided in Section 5 and except that Sections 1, 7 and 8 shall survive any such termination and remain in full force and effect. 7. INDEMNIFICATION. (a) INDEMNIFICATION OF INITIAL PURCHASERS. The Company agrees to indemnify and hold harmless each Initial Purchaser, the directors, officers, employees and agents of each Initial Purchaser and each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any and all losses, liabilities (joint or several), claims, damages and expenses whatsoever, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law 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 a material fact contained in the Offering Circular (or any amendment or supplement thereto), or arise out of or are based upon the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; 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 any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Initial Purchaser through the Initial Purchasers specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have. 15 (b) INDEMNIFICATION OF COMPANY, DIRECTORS AND OFFICERS. Each Initial Purchaser severally agrees to indemnify and hold harmless the Company, each of its directors (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company) and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any and all losses, liabilities (joint or several), claims, damages and expenses described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to written information furnished to the Company by such Initial Purchaser through Goldman, Sachs & Co. specifically for inclusion in the documents referred to in the foregoing indemnity. The Company acknowledges that the statements set forth in the last paragraph of the cover page regarding delivery of the Securities, the paragraph related to stabilization on the reverse of the cover page and, under the heading "Plan of Distribution," the paragraph related to stabilization in the Offering Circular constitute the only information furnished in writing by or on behalf of the several Initial Purchasers for inclusion in such Offering Circular. (c) ACTIONS AGAINST PARTIES; NOTIFICATION. Each indemnified party shall give written 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 (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party's choice at the indemnifying party's expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); PROVIDED, HOWEVER, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party's election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. 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 16 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. 8. CONTRIBUTION. If the indemnification provided for in Section 7 hereof is for any reason 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 (including legal or other expenses reasonably incurred in connection with investigating or defending same) 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 (provided that in no case shall any Initial Purchaser (except as may be provided in any agreement among Initial Purchasers relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by such Initial Purchaser hereunder) or (ii) if the allocation provided by clause (i) is unavailable for any reason, 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 bear to the total underwriting discounts and commissions received by the Initial Purchasers, in each case as set forth in the Offering Circular. 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. 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 underwritten by it and distributed to investors were offered to investors exceeds the amount of any damages which such Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this Section 8, 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. 17 For purposes of this Section 8, each person, if any, who controls an Initial Purchaser within the meaning of Section 15 of the Act or Section 20 of the Exchange 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 Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company. The Initial Purchasers' respective obligations to contribute pursuant to this Section 8 are several in proportion to the number of Securities set forth opposite their respective names in Schedule I hereto and not joint. 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 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. 10. TERMINATION OF AGREEMENT. (a) TERMINATION; GENERAL. This Agreement shall be subject to termination in the absolute discretion of the Initial Purchasers, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in the Company's Common Stock shall have been suspended by the Commission or The Nasdaq Stock Market, Inc. ("Nasdaq") or trading in securities generally on the New York Stock Exchange or the Nasdaq shall have been suspended or limited or minimum prices shall have been established on such Exchange or Nasdaq, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities or (iii) there shall have occurred subsequent to the signing hereof any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Initial Purchasers, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Offering Circular (exclusive of any supplement thereto). (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 5 hereof, and provided further that Sections 1, 7 and 8 shall survive such termination and remain in full force and effect. 11. DEFAULT BY ONE OR MORE OF THE INITIAL PURCHASERS. If any one or more of the Initial Purchasers shall fail to purchase and pay for any of the Securities agreed to be purchased by such Initial Purchaser or Initial Purchasers hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Initial Purchasers shall be obligated severally to take up and pay for (in the respective proportions which the amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate amount of Securities set forth opposite the names of all the remaining Initial Purchasers) the Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase; PROVIDED, HOWEVER, that in the event that the aggregate amount of Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase shall exceed 10% of the aggregate amount of Securities set forth in Schedule I hereto, the remaining Initial Purchasers shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, 18 and if such nondefaulting Initial Purchasers do not purchase all of the Securities, this Agreement will terminate without liability to any nondefaulting Initial Purchaser or the Company. In the event of a default by any Initial Purchaser as set forth in this Section 11, the Closing Time shall be postponed for such period, not exceeding five Business Days, as the Initial Purchasers shall determine in order that the required changes in the Offering Circular or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Initial Purchaser of its liability, if any, to the Company and any nondefaulting Initial Purchaser for damages occasioned by its default hereunder. 12. RELIANCE; NOTICES. In all dealings hereunder, the Initial Purchasers shall act on behalf of each of the Initial Purchasers, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Initial Purchaser made or given by the Initial Purchasers jointly or by Goldman, Sachs & Co. on their behalf. All statements, requests, notices and agreements hereunder shall be in writing, and if to the Initial Purchasers shall be delivered or sent by mail, telex or facsimile transmission to the Initial Purchasers in care of Goldman, Sachs & Co., Attention: Registration Department (fax no.

Any such statements, requests, notices or agreements shall take effect upon receipt thereof. 13. PARTIES. This Agreement shall inure to the benefit of and be binding upon the Initial Purchasers, 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, the Company and the controlling persons and officers and directors referred to in Sections 7 and 8 and their respective heirs, executors, administrators, successors and assigns 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, the Company and said controlling persons and officers and directors and their respective heirs, executors, administrators, successors and assigns, 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. 14. TIME OF THE ESSENCE. Time shall be of the essence of this Agreement. As used herein, the term "business day" shall mean any day when the Commission's office in Washington, D.C. is open for business. 15. GOVERNING LAW AND TIME.

The Initial Purchasers represent that they have offered and sold the Securities, and will offer and sell the Securities (i) as part of their distribution at any time and (ii) otherwise until 40 days after the later of the commencement of the offering and the Closing Date, only in accordance with Rule 903 of Regulation S or Rule 144A under the Act. Accordingly, the Initial Purchasers agree that neither they nor any persons acting on their behalf has engaged or will engage in any directed selling efforts with respect to the Securities, and they have complied and will comply with the offering restrictions requirement of Regulation S. The Initial Purchasers agree that, at or prior to confirmation of sale of Securities (other than a sale pursuant to Rule 144A), they will have sent to each distributor, dealer or person receiving a selling concession, fee or other remuneration that purchases Securities from it during the restricted period a confirmation or notice to substantially the following effect: "THE SECURITIES COVERED HEREBY HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933 (THE "SECURITIES ACT") AND MAY NOT BE OFFERED AND SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS (I) AS PART OF THEIR DISTRIBUTION AT ANY TIME OR (II) OTHERWISE UNTIL 40 DAYS AFTER THE LATER OF THE COMMENCEMENT OF THE OFFERING AND THE CLOSING DATE, EXCEPT IN EITHER CASE IN ACCORDANCE WITH REGULATION S (OR RULE 144A IF AVAILABLE) UNDER THE SECURITIES ACT. TERMS USED ABOVE HAVE THE MEANING GIVEN TO THEM BY REGULATION S." Terms used in this paragraph have the meanings given to them by Regulation S. The Initial Purchasers further agree that they have not entered and will not enter into any contractual arrangement with respect to the distribution or delivery of the Securities, except with their affiliates or with the prior written consent of the Company. (2) The Initial Purchasers further agree, on behalf of themselves and their affiliates, that (a) they have not offered or sold and, prior to the date six months after the date of issue of the Securities, will not offer or sell any Securities to persons in the United Kingdom except to persons whose ordinary activities involve them in acquiring, holding, managing or disposing of investments (as principal or agent) for the purpose of their businesses or otherwise in circumstances which have not resulted and will not result in an offer to the public in the United Kingdom within the meaning of the Public Offers of Securities Regulations 1995, (b) they have complied, and will comply, with all applicable provisions of the Financial Services Act 1996 of Great Britain with respect to anything done by them in relation to the Securities in, from or otherwise involving the United Kingdom and (c) they have only issued or passed on and will only issue or pass on in the United Kingdom any document received by them in connection with the issuance of the Securities to a person who is of a kind described in Article 11(3) of the Financial Services Act 1986 (Investment Advertisements) (Exemptions) Order 1996 of Great Britain or is a person to whom the document may otherwise lawfully be issued or passed on. 23 Exhibit A-1 FORM OF OPINION OF WILLKIE FARR & GALLAGHER TO BE DELIVERED PURSUANT TO SECTION 6(a) (i) The Company has been duly incorporated and is validly existing as a corporation under the laws of the State of Delaware. (ii) The Company has power and authority to own, lease and operate its properties and to conduct its business as described in the Offering Circular and to enter into and perform its obligations under the Purchase Agreement. (iii) The Company is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not result in a Material Adverse Effect. (iv) The authorized, issued and outstanding capital stock of the Company is as set forth in the Offering Circular as of the dates indicated therein; the shares of issued and outstanding capital stock of the Company have been duly authorized and validly issued and are fully paid and non-assessable; and none of the outstanding shares of capital stock of the Company was issued in violation of the preemptive or other similar rights of any securityholder of the Company. (v) Each Designated Subsidiary has been duly formed and is validly existing as a corporation, limited liability company or limited partnership in good standing, as applicable, under the laws of the jurisdiction of its formation, and has power and authority to own, lease and operate its properties and to conduct its business as described in the Offering Circular; all of the issued and outstanding shares, membership interests or partnership interests of each Designated Subsidiary have been duly authorized and validly issued, are fully paid and non-assessable and, except as otherwise set forth in the Offering Circular in respect of the minority interests described therein, are owned by the Company, directly or through subsidiaries, free and clear of any security interest, mortgage, pledge, lien, encumbrance, claim or equity. (vi) The Purchase Agreement and the Registration Rights Agreement have 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, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors' rights and to general equity principles, PROVIDED that such counsel need express no opinion as to the enforceability of provisions with respect to indemnity for liabilities arising under the Securities Act of 1933, as amended. (vii) The Indentures have been duly authorized, executed and delivered; and, assuming due execution by the Trustee, the Indentures constitute valid and legally binding obligations of the Company enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors' rights and to general equity principles. A-1-1 (viii) The Securities have been duly authorized and executed by the Company and authenticated, issued and delivered in accordance with the Indentures and constitute valid and legally binding obligations of the Company entitled to the benefits provided by the Indentures, subject, as to enforcement, to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors' rights and to general equity principles. In rendering the opinion set forth in this paragraph (viii), as to authentication we have relied solely on a certificate of the Trustee as to the authentication of the Securities by a duly authorized representative of the Trustee and have assumed that the Securities so authenticated have been delivered to you and paid for by you in accordance with the Purchase Agreement. The Securities and the Indentures conform in all material respects to the descriptions thereof in the Offering Circular; (ix) The Exchange Securities have been duly and validly authorized by the Company and, when executed by the Company, authenticated by the Trustee in accordance with the provisions of the Indentures and when the Indentures have been duly qualified under the Trust Indenture Act and the Exchange Securities have been exchanged for the Securities pursuant to the Registration Rights Agreement, will constitute valid and legally binding obligations of the Company, entitled to the benefits of the Indentures, and enforceable against the Company in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors' rights and to general equity principles. (x) The information in the Offering Circular under the caption "Description of the Notes", to the extent that it constitutes a summary of the terms of the Securities, and under the caption "Plan of Distribution", and under the caption "Regulation" when considered together with the information under the caption "Business--Regulatory Overview" included in the Company's Annual Report on Form 10-K, filed on March 29, 1999, which is incorporated therein by reference, to the extent that it constitutes matters of law, summaries of legal matters, or legal conclusions, has been reviewed by us and is correct in all material respects. (xi) The statements set forth in the Offering Circular under the caption "Material United States Federal Income Tax Consequences", insofar as such statements purport to summarize certain United States federal income and estate tax consequences of the ownership and dispensation of the Securities by certain U.S. Holders and non-U.S. Holders (as such terms are defined therein) of the Securities, provide a fair summary of such consequences under current law. (xii) All descriptions in the Offering Circular of contracts and other documents to which the Company or any of its subsidiaries are a party are accurate in all material respects; to the best of our knowledge, there are no franchises, contracts, indentures, mortgages, loan agreements, notes, leases or other instruments that would be required to be described in the Offering Circular that are not described or referred to in the Offering Circular other than those described or referred to therein and the descriptions thereof or references thereto are correct in all material respects. A-1-2 (xiii) The documents incorporated by reference in the Offering Circular (other than the financial statements and related schedules therein, as to which such counsel need express no opinion), as of the date of the Offering Circular, complied as to form in all material respects with the requirements of the Exchange Act and the rules and regulations of the Commission thereunder. (xiv) To our best knowledge, neither the Company nor any of its subsidiaries is in violation of its charter or by-laws or other constituting or operative document or agreement and, to the best of our knowledge, no default by the Company or any of its subsidiaries exists in the due performance or observance of any material obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, loan agreement, note, lease or other agreement or instrument that is described or referred to in the Offering Circular. (xv) No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental authority or agency is necessary or required for the performance by the Company of its obligations under the Purchase Agreement, the Registration Rights Agreement or the Indentures, in connection with the offering, issuance or sale of the Securities hereunder or thereunder or the consummation of the actions contemplated by the Purchase Agreement, the Registration Rights Agreement or the Indentures, except such as may be required under the Act and the Trust Indenture Act in connection with the Exchange Offer. (xvi) The issue and sale of the Securities, the execution, delivery and performance of the Purchase Agreement, the Indentures, the Securities, the Registration Rights Agreement and any other agreement or instrument entered into or issued or to be entered into or issued by the Company in connection with the transactions contemplated hereby, thereby or in the Offering Circular, and the consummation of the transactions contemplated herein, therein and in the Offering Circular (including the issuance and sale of the Securities by the Company hereunder), the compliance by the Company with its obligations hereunder and thereunder have been duly authorized by all necessary corporate action on the part of the Company and do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default or a Repayment Event under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any of its subsidiaries, 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 of its subsidiaries 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 subsidiaries thereof is subject, except for such conflicts, breaches or defaults or liens, charges or encumbrances that, singly or in the aggregate, would not result in a Material Adverse Effect, nor will such action result in any violation of the provisions of the constituting or operative document or agreement of the Company or any of its subsidiaries or any applicable law, statute, rule, regulation, judgment, order, writ or decree of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Company or any of its subsidiaries or any of their assets or properties. (xvii) The Company is not, and upon the issuance and sale of the Securities and the application of the net proceeds therefrom will not be, an "investment company" or an entity "controlled" by an "investment company," as such terms are defined in the 1940 Act. A-1-3 Such counsel shall also state that although such counsel does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Offering Circular, except for those referred to, and to the extent stated, in subsections (x), (xi) and (xii) of this opinion, nothing has come to the attention of such counsel that would lead them to believe that, as of its date, the Offering Circular or any further amendment or supplement thereto made by the Company prior to each Closing Time or any documents incorporated by reference therein (other than the financial statements and related schedules therein, as to which such counsel need express no opinion) contained an untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading or that, as of such Closing Time, the Offering Circular or any further amendment or supplement thereto made by the Company prior to such Closing Time or any documents incorporated by reference therein (other than the financial statements and related schedules therein, as to which such counsel need express no opinion) contains an untrue statement of a material fact or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. In rendering such opinion, such counsel (A) may rely (i) as to matters involving the application of the laws of the State of Washington, upon the opinion of the General Counsel or Securities Counsel of the Company (which opinion shall be dated and furnished to the Initial Purchasers at the Closing Time, shall be satisfactory in form and substance to counsel for the Initial Purchasers and shall expressly state that the Initial Purchasers may rely on such opinion as if it were addressed to them), provided that Willkie Farr & Gallagher shall state in their opinion that they believe that they and the Initial Purchasers are justified in relying upon such opinion, and (ii) as to matters of fact (but not as to legal conclusions), to the extent they deem proper, on certificates of responsible officers of the Company and public officials and (B) may state that they express no opinion as to the laws of any jurisdiction outside the United States. Such opinion shall not state that it is to be governed or qualified by, or that it is otherwise subject to, any treatise, written policy or other document relating to legal opinions, including, without limitation, the Legal Opinion Accord of the ABA Section of Business Law (1991). A-1-4 Exhibit A-2 FORM OF OPINION OF GENERAL COUNSEL OR SECURITIES COUNSEL TO BE DELIVERED PURSUANT TO SECTION 6(a) (i) There is not pending or, to the best of my knowledge, threatened any action, suit, proceeding, inquiry or investigation, to which the Company or any subsidiary thereof is a party, or to which the property of the Company or any subsidiary thereof is subject, before or brought by any court or governmental agency or body, which could reasonably be expected to result in a Material Adverse Effect, or which might reasonably be expected to materially and adversely affect the properties or assets thereof or the consummation of the transactions contemplated in the Purchase Agreement, the Indentures, the Registration Rights Agreement or the Securities or the performance by the Company of its obligations thereunder or the transactions contemplated by the Offering Circular. (ii) To the best of my knowledge and except as set forth in or contemplated by the Offering Circular with respect to systems under development, (a) each of the Company and its Designated Subsidiaries has all Authorizations of and from, and has made all declarations and filings with, all Federal, state, local and other governmental authorities, all self-regulatory organizations and all courts and other tribunals, which are necessary or appropriate for the Company and its Designated Subsidiaries to own, lease, license, use and construct its properties and assets and to conduct its business in the manner described in the Offering Circular, except to the extent that the failure to obtain any such Authorizations or make any such declaration or filing would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect, (b) all such Authorizations are in full force and effect with respect to the Company and its Designated Subsidiaries, (c) no event has occurred that management of the Company reasonably believes is likely to result in the revocation, termination or modification of any such Authorization and (d) the Company and its Designated Subsidiaries are in compliance in all material respects with the terms and conditions of all such Authorizations and with the rules and regulations of the regulatory authorities and governing bodies having jurisdiction with respect thereto. (iii) To the best of my knowledge, neither the execution and delivery of the Purchase Agreement, the Indentures, the Registration Rights Agreement or the Securities, nor the consummation by the Company of the transactions contemplated hereby or thereby will cause any suspension, revocation, impairment, forfeiture, nonrenewal or termination of any Authorization. In rendering such opinion, such counsel (A) may rely as to matters of fact (but not as to legal conclusions), to the extent he deems proper, on certificates of responsible officers of the Company and public officials and (B) may state that he expresses no opinion as to the laws of any jurisdiction outside the United States. Such opinion shall not state that it is to be governed or qualified by, or that it is otherwise subject to, any treatise, written policy or other document relating to legal opinions, including, without limitation, the Legal Opinion Accord of the ABA Section of Business Law (1991).
