(e) Winthrop, Stimson, Putnam & Roberts, Orrick, Herrington & Sutcliffe and David Kinnard, Esq., General Counsel of PPL Montana, shall have furnished to the Initial Purchasers their written opinion, as transaction counsel to PPL Montana, addressed to the Initial Purchasers and dated as of the Closing Date, in form and substance reasonably satisfactory to the Initial Purchasers, substantially to the aggregate effect set forth in Annex B hereto.

Beck are based upon assumptions which are consistent in all material respects with the Operative Documents and the Transaction Documents and which, to the extent material for purposes of consideration of the Projections taken as a whole, are disclosed in the Offering Memorandum; in their opinion, the Projections are reasonable in light of the assumptions made therein; it is understood that, despite their good faith assumptions and reasonable beliefs (A) the assumptions on which the Projections are based are subject to significant uncertainties and contingencies, many of which are beyond the control of PPL Montana, (B) there can be no assurance that the -21- 22 financial results reflected in the Projections will be realized, (C) the actual results of PPL Montana will differ from the Projections and such differences may be material, and (D) the Projections are not necessarily indicative of current value or future performance; (v) in their opinion, the information provided by PPL Montana to the Independent Engineer, Independent Market Consultant and the Independent Fuel Consultant, in the preparation of their reports set forth at Appendices A, B and C, respectively, to the Offering Memorandum is not incomplete or incorrect in any material respect; and (vi) the Tax Indemnity Agreement executed on the Closing Date is substantially in the form of the Tax Indemnity Agreement reviewed by counsel to the Initial Purchasers on July 10, 2000 and any changes, additions or amendments made thereto since July 10, 2000 will not result in a material detrimental effect on the Initial Purchasers.

(o) Subsequent to the execution and delivery of this Agreement or, if earlier, the dates as of which information is given in the Offering Memorandum (exclusive of any amendment or supplement thereto), there shall not have been any change in the member interests or long-term debt or any change, or any development involving a prospective -22- 23 change, in or affecting the condition (financial or otherwise), results of operations or business of PPL Montana and its subsidiaries taken as a whole, the effect of which, in any such case described above, is, in the judgment of CSI as representative of the Initial Purchasers, so material and adverse as to make it impracticable or inadvisable to proceed with the sale or delivery of the Certificates on the terms and in the manner contemplated by this Agreement and the Offering Memorandum (exclusive of any amendment or supplement thereto). (p) No action shall have been taken and no statute, rule, regulation or order shall have been enacted, adopted or issued by any governmental agency or body which would, as of the Closing Date, prevent the issuance or sale of the Certificates; and no injunction, restraining order or order of any other nature by any federal or state court of competent jurisdiction shall have been issued as of the Closing Date which would prevent the issuance or sale of the Certificates.

(s) Subsequent to the execution and delivery of this Agreement there shall not have occurred any of the following: (i) trading in securities generally on the New York Stock Exchange, the American Stock Exchange or the over-the-counter market shall have been suspended or limited, or minimum prices shall have been established on any such exchange or market by the Commission, by any such exchange or by any other regulatory body or governmental authority having jurisdiction, or trading in any securities of PPL Montana on any exchange or in the over-the-counter market shall have been suspended; -23- 24 (ii) a declaration of any moratorium on commercial banking activities by federal or New York state authorities; (iii) an outbreak or escalation of hostilities or a declaration by the United States of a national emergency or war; or (iv) a material adverse change in general economic, political or financial conditions (or the effect of international conditions on the financial markets in the United States shall be such) the effect of which, in the case of this clause (iv), is, in the judgment of the Initial Purchasers, so material and adverse as to make it impracticable or inadvisable to proceed with the sale or the delivery of the Certificates on the terms and in the manner contemplated by this Agreement and in the Offering Memorandum (exclusive of any amendment or supplement thereto). (t) There shall exist at and as of the Closing Date no conditions that would constitute an event of default (or an event that with notice or the lapse of time, or both, would constitute an event of default) under the Facility Leases or, to PPL Montana's knowledge, Lessor Notes or the Certificates.

All conditions, agreements, opinions, letters, evidence, certificates and other documents mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance or otherwise reasonably satisfactory to counsel for the Initial Purchasers. 6. Termination. The obligations of the Initial Purchasers hereunder may be terminated by the Initial Purchasers, in their absolute discretion, by notice given to and received by PPL Montana prior to delivery of and payment for the Certificates if, prior to that time, any of the events described in Section 5(n), (o), (p), (r) or (s) shall have occurred and be continuing. 7. Defaulting Initial Purchasers. (a) If, on the Closing Date, any Initial Purchaser defaults in the performance of its obligations under this Agreement, the non-defaulting Initial Purchasers may make arrangements for the purchase of the Certificates which such defaulting Initial Purchaser agreed but failed to purchase by other persons satisfactory to PPL Montana and the non-defaulting Initial Purchasers, but if no such arrangements are made within 36 hours after such default, this Agreement shall terminate without liability on the part of the non-defaulting Initial Purchasers or PPL Montana, except that PPL Montana will continue to be liable for the payment of expenses to the extent set forth in Sections 8 and 12 and except that the provisions of Sections 9 and 10 shall not terminate and shall remain in effect. As used in this Agreement, the term "Initial Purchasers" includes, for all purposes of this Agreement unless the context otherwise requires, any party not listed in Schedule 1 hereto that, pursuant to this Section 7, purchases Certificates which a defaulting Initial Purchaser agreed but failed to purchase. (b) Nothing contained herein shall relieve a defaulting Initial Purchaser of any liability it may have to PPL Montana or any non-defaulting Initial Purchaser for damages caused by its default. If other persons are obligated or agree to purchase the Certificates of a defaulting Initial Purchaser, either the non-defaulting Initial Purchasers or PPL Montana may postpone the Closing Date for up to seven full business days in order to effect any changes that in the opinion of counsel for PPL Montana or counsel for the Initial Purchasers may be necessary in the Offering Memorandum or in any other -25- 26 document or arrangement, and PPL Montana agrees to promptly prepare any amendment or supplement to the Offering Memorandum that effects any such changes. 8. Reimbursement of Initial Purchasers' Expenses. If (a) this Agreement shall have been terminated pursuant to Section 6 or 7, (b) PPL Montana shall fail to cause the Trust to tender the Certificates for delivery to the Initial Purchasers for any reason or (c) the Initial Purchasers shall decline to purchase the Certificates for any reason permitted under this Agreement, PPL Montana shall reimburse the Initial Purchasers for such out-of-pocket expenses (including reasonable fees and disbursements of counsel) as shall have been reasonably incurred by the Initial Purchasers in connection with this Agreement and the proposed purchase and resale of the Certificates. If this Agreement is terminated pursuant to Section 7 by reason of the default of one or more of the Initial Purchasers, PPL Montana shall not be obligated to reimburse any defaulting Initial Purchaser on account of such expenses. 9. Indemnification. (a) PPL Montana shall indemnify and hold harmless each Initial Purchaser, its affiliates, their respective officers, directors, employees, representatives and agents, and each person, if any, who controls any Initial Purchaser within the meaning of the Securities Act or the Exchange Act (collectively referred to for purposes of this Section 9(a) and Section 10 as an Initial Purchaser), from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, without limitation, any loss, claim, damage, liability or action relating to purchases and sales of the Certificates), to which that Initial Purchaser may become subject, whether commenced or threatened, under the Securities Act, the Exchange Act, any other federal or state statutory law or regulation, at common law or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon: (i) any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum or the Offering Memorandum or in any amendment or supplement thereto or in any information provided by PPL Montana pursuant to Section 4(e); or (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, and shall reimburse each Initial Purchaser promptly upon demand for any legal or other expenses reasonably incurred by that Initial Purchaser in connection with investigating or defending or preparing to defend against or appearing as a third party witness in connection with any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that PPL Montana shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, an untrue -26- 27 statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with any Initial Purchasers' Information; and provided, further, that with respect to any such untrue statement in or omission from the Preliminary Offering Memorandum, the indemnity agreement contained in this Section 9(a) shall not inure to the benefit of any such Initial Purchaser to the extent that the sale to the person asserting any such loss, claim, damage, liability or action was an initial resale by such Initial Purchaser and any such loss, claim, damage, liability or action of or with respect to such Initial Purchaser results from the fact that both (A) to the extent required by applicable law, a copy of the Offering Memorandum was not sent or given to such person at or prior to the written confirmation of the sale of such Certificates to such person and (B) the untrue statement in or omission from the Preliminary Offering Memorandum was corrected in the Offering Memorandum unless, in either case, such failure to deliver the Offering Memorandum was a result of non-compliance by PPL Montana with Section 4(b). (b) Each Initial Purchaser, severally and not jointly, shall indemnify and hold harmless PPL Montana and its officers, members, managers, employees, representatives and agents, and each person, if any, who controls PPL Montana within the meaning of the Securities Act or the Exchange Act (collectively referred to for purposes of this Section 9(b) and Section 10 as PPL Montana), from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which PPL Montana may become subject, whether commenced or threatened, under the Securities Act, the Exchange Act, any other federal or state statutory law or regulation, at common law or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon: (i) any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum or the Offering Memorandum or in any amendment or supplement thereto; or (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with any Initial Purchasers' Information furnished by such Initial Purchaser, and shall reimburse PPL Montana for any legal or other expenses reasonably incurred by PPL Montana in connection with investigating or defending or preparing to defend against or appearing as a third party witness in connection with any such loss, claim, damage, liability or action as such expenses are incurred. (c) Promptly after receipt by an indemnified party under this Section 9 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party pursuant to -27- 28 Section 9(a) or 9(b), notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 9 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 9. If any such claim or action shall be brought against an indemnified party, and the indemnified party shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 9 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that an indemnified party shall have the right to employ its own counsel in any such action, but the fees, expenses and other charges of such counsel for the indemnified party will be at the expense of such indemnified party unless: (i) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party; (ii) the indemnified party has reasonably concluded (based upon advice of counsel to the indemnified party) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party; (iii) a conflict or potential conflict exists (based upon advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party); or (iv) the indemnifying party has not in fact employed counsel reasonably satisfactory to the indemnified party to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action; in each of which cases the reasonable fees, disbursements and other charges of counsel will be at the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm of attorneys (in addition to any local counsel) at any one time for all such indemnified party or parties. Each indemnified party, as a condition of the indemnity agreements contained in Sections 9(a) and 9(b), shall use all -28- 29 reasonable efforts to cooperate with the indemnifying party in the defense of any such action or claim. No indemnifying party shall be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with its written consent or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld), 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 and does not include an admission of fault, culpability or failure to act by or on behalf of any indemnified party. The obligations of PPL Montana and the Initial Purchasers in this Section 9 and in Section 10 are in addition to any other liability that PPL Montana or the Initial Purchasers, as the case may be, may otherwise have, including in respect of any breaches of representations, warranties and agreements made herein by any such party. 10. Contribution. If the indemnification provided for in Section 9 is unavailable or insufficient to hold harmless an indemnified party under Section 9(a) or 9(b), then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof: (i) in such proportion as shall be appropriate to reflect the relative benefits received by PPL Montana, on the one hand, and the Initial Purchasers, on the other, from the offering of the Certificates; 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 PPL Montana, on the one hand, and the Initial Purchasers, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by PPL Montana, on the one hand, and the Initial Purchasers, on the other, with respect to such offering shall be deemed to be in the same proportion as (i) the difference of the aggregate principal amount of the Certificates minus the fees paid to the Initial Purchasers pursuant to Section 2(a) hereof with respect to the Certificates purchased under this Agreement, on the one hand, and (ii) the fees paid to the Initial Purchasers pursuant to Section 2(a) hereof with respect to the Certificates purchased under this Agreement, on the other, bear to the aggregate principal amount of the Certificates. The relative fault shall be determined by reference -29- 30 to, among other things, (A) whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to PPL Montana, the Trust or the Owner Lessors or information supplied by PPL Montana, on the one hand, or relates to any Initial Purchasers' Information, on the other, (B) the intent of the parties and (C) their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. PPL Montana and the Initial Purchasers agree that it would not be just and equitable if contributions pursuant to this Section 10 were to be 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 that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 10 shall be deemed to include, for purposes of this Section 10, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending or preparing to defend any such action or claim. Notwithstanding the provisions of this Section 10, no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the fees received by such Initial Purchaser pursuant to Section 2(a) hereof with respect to the Certificates purchased by it under this Agreement exceeds the amount of any damages which such Initial Purchaser has otherwise paid or become liable to pay by reason of any 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 Initial Purchasers' obligations to contribute as provided in this Section 10 are several in proportion to their respective purchase obligations and not joint. 11. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the Initial Purchasers, PPL Montana and their respective successors. This Agreement and the terms and provisions hereof are for the sole benefit of only those persons, except as provided in Sections 9 and 10 with respect to officers, directors, members, managers, employees, representatives, agents and controlling persons of PPL Montana and the Initial Purchasers and in Section 4(e) with respect to holders and prospective purchasers of the Certificates. Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 11, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. 12.

PPL Montana agrees with the Initial Purchasers to pay: (a) the costs incident to the authorization, issuance, sale, preparation and delivery of the Certificates and any taxes payable in that connection; -30- 31 (b) the costs incident to the preparation, printing and distribution of the Preliminary Offering Memorandum, the Offering Memorandum and any amendments or supplements thereto; (c) the costs of reproducing and distributing each of the Transaction Documents; (d) the costs incident to the preparation, printing and delivery of the certificates evidencing the Certificates, including stamp duties and transfer taxes, if any, payable upon issuance of the Certificates; (e) the fees, disbursements and expenses of the Initial Purchasers' counsel and the fees and expenses of PPL Montana's counsel and independent accountants; (f) the fees and expenses of qualifying the Certificates under the securities laws of the several jurisdictions as provided in Section 4(g) and of preparing, printing and distributing Blue Sky Memoranda (including related fees and expenses of counsel for the Initial Purchasers); (g) any fees charged by rating agencies for rating the Certificates; (h) the fees and expenses of the Pass Through Trustee, any paying agent (including related fees and expenses of any counsel to such parties) and their respective counsel; (i) furnishing such copies of the Preliminary Offering Memorandum and the Offering Memorandum, and all amendments and supplements thereof, as may be reasonably requested by the Initial Purchasers for use in connection with the resales of the Certificates in accordance with Section 2; (j) all "road show" fees and expenses incurred in connection with the offering of the Certificates; (k) the fees, disbursements and expenses of John T. Boyd Company, R.W. Beck, Inc. and PHB Hagler Bailly, Inc. in connection with the preparation of the reports of such parties included in the Offering Memorandum; (l) the fees, disbursements and expenses of the Initial Purchasers relating to the Lease Transactions (including, without limitation, travel and due diligence expenses); (m) the financial advisory fees of Chase Securities Inc.; and (n) all other costs and expenses incident to the performance of the obligations of PPL Montana under this Agreement which are not otherwise specifically provided for in this Section 12. -31- 32 13. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of PPL Montana and the Initial Purchasers contained in this Agreement or made by or on behalf of PPL Montana or the Initial Purchasers pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Certificates and shall remain in full force and effect, regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of any of them or any of their respective affiliates, officers, directors, members, managers, employees, representatives, agents or controlling persons. 14.

(ii) in their opinion, the audited financial statements and pro forma financial information included in the Offering Memorandum and reported on by them comply in form in all material respects with the accounting requirements of the Exchange Act and the related published rules and regulations of the Commission thereunder that would apply to the Offering Memorandum if the Offering Memorandum were a prospectus included in a registration statement on Form S-1 under the Securities Act (except that certain supporting schedules are omitted); (iii) based upon a reading of the latest unaudited financial statements made available by PPL Montana, the procedures of the AICPA for a review of interim financial information as described in Statement of Auditing Standards No. 71, reading of minutes and inquiries of certain officials of PPL Montana who have responsibility for financial and accounting matters and certain other limited procedures requested by the Initial Purchasers and described in detail in such letter, nothing has come to their attention that causes them to believe that: (A) any unaudited financial statements included in the Offering Memorandum do not comply as to form in all material respects with applicable accounting requirements; (B) any material modifications should be made to the unaudited financial statements included in the Offering Memorandum for them to be in conformity with generally accepted accounting principles applied on a basis substantially consistent with that of the audited financial statements included in the Offering Memorandum; or (C) the information included under the headings "Summary -- Summary Consolidated Financial Information and Operating Data," "Capitalization," "Selected Financial Data," "Discussion and Analysis of Financial Condition" and "Management -- Compensation of Management" is not in conformity with the disclosure requirements of Regulation S-K that would apply to the Offering Memorandum if the Offering Memorandum were a prospectus included in a registration statement on Form S-1 under the Securities Act; i 43 (iv) based upon the procedures detailed in such letter with respect to the period subsequent to the date of the last available balance sheet, including reading of minutes and inquiries of certain officials of PPL Montana who have responsibility for financial and accounting matters, nothing has come to their attention that causes them to believe that: (A) at a specified date not more than three business days prior to the date of such letter, there was any change in capital stock, increase in long-term debt or decrease in net current assets as compared with the amounts shown in the [_____], 2000 unaudited balance sheet included in the Offering Memorandum or (B) for the period from [_____], 2000 to a specified date not more than three business days prior to the date of such letter, there were any decreases, as compared with the corresponding period in the preceding year, in net sales, income from operations, EBITDA or net income, except in all instances for changes, increases or decreases that the Offering Memorandum discloses have occurred or which are set forth in such letter, in which case the letter shall be accompanied by an explanation by PPL Montana as to the significance thereof unless said explanation is not deemed necessary by the Initial Purchasers; (v) they have performed certain other specified procedures as a result of which they determined that certain information of an accounting, financial or statistical nature (which is limited to accounting, financial or statistical information derived from the general accounting records of PPL Montana) set forth in the Offering Memorandum agrees with the accounting records of PPL Montana, excluding any questions of legal interpretation; and (vi) on the basis of a reading of the unaudited pro forma financial information included in the Offering Memorandum, carrying out certain specified procedures, reading of minutes and inquiries of certain officials of PPL Montana who have responsibility for financial and accounting matters and proving the arithmetic accuracy of the application of the pro forma adjustments to the historical amounts in the pro forma financial information, nothing came to their attention which caused them to believe that the pro forma financial information does not comply in form in all material respects with the applicable accounting requirements of Rule 11-02 of Regulation S-X or that the pro forma adjustments have not been properly applied to the historical amounts in the compilation of such information. ii 44 ANNEX D FORM OF PURCHASER'S LETTER Chase Securities Inc.
