Ladies and Gentlemen:

                  The Colstrip Pass Through Trust (the "Trust"), a newly formed
trust created by PPL Montana, LLC, a Delaware limited liability company ("PPL
Montana"), proposes to issue and sell $338,000,000 aggregate principal amount of
Pass Through Certificates, due 2020 (the "Certificates"). The Certificates will
be issued pursuant to a Pass Through Trust Agreement to be dated as of July 13,
2000 (the "Pass Through Trust Agreement") between PPL Montana and The Chase
Manhattan Bank, N.A., as trustee (the "Pass Through Trustee"). The assets of the
Trust will consist solely of notes (the "Lessor Notes") to be issued by four
owner lessors (the "Owner Lessors"), each pursuant to an indenture
(collectively, the "Lease Indentures") between an Owner Lessor and The Chase
Manhattan Bank, N.A., as trustee (the "Lease Indenture Trustee"), in connection
with the related sale-leaseback transaction (collectively, the "Lease
Transactions"). PPL Montana hereby confirms its agreement with Chase Securities
Inc. ("CSI"), Credit Suisse First Boston Corporation, UBS Warburg LLC and TD
Securities (USA) Inc. (collectively, the "Initial Purchasers") concerning the
purchase of the Certificates from the Trust by the several Initial Purchasers.

                  The Certificates will be offered and sold to the Initial
Purchasers without being registered under the Securities Act of 1933, as amended
(the "Securities Act"), in reliance upon an exemption therefrom. PPL Montana has
prepared a preliminary offering memorandum dated July 5, 2000 (the "Preliminary
Offering Memorandum") and will prepare an offering memorandum dated the date
hereof (the "Offering Memorandum") setting forth information concerning PPL
Montana, the Trust, the Owner Lessors, the Lessor Notes and the Certificates.
Copies of the
<PAGE>   2
Preliminary Offering Memorandum have been, and copies of the Offering Memorandum
will be, delivered by PPL Montana to the Initial Purchasers pursuant to the
terms of this Agreement. Any references herein to the Preliminary Offering
Memorandum and the Offering Memorandum shall be deemed to include all amendments
and supplements thereto, unless otherwise noted. PPL Montana hereby confirms
that it has authorized the use of the Preliminary Offering Memorandum and the
Offering Memorandum in connection with the offering and resale of the
Certificates by the Initial Purchasers in accordance with Section 2.

                  Holders of the Certificates (including the Initial Purchasers
and their direct and indirect transferees) will be entitled to the benefits of
an Exchange and Registration Rights Agreement, substantially in the form
attached hereto as Annex A (the "Registration Rights Agreement"), pursuant to
which PPL Montana will agree to file with the Securities and Exchange Commission
(the "Commission") (i) a registration statement under the Securities Act (the
"Exchange Offer Registration Statement") registering an issue of Pass Through
Certificates of the Trust (the "Exchange Certificates") which are identical in
all material respects to the Certificates (except that the Exchange Certificates
will not contain terms with respect to transfer restrictions) and (ii) under
certain circumstances, a shelf registration statement pursuant to Rule 415 under
the Securities Act (the "Shelf Registration Statement").

                  Capitalized terms used but not defined herein shall have the
meanings given to such terms in the Participation Agreements (as defined in
Section 1).

                  1. Representations, Warranties and Agreements of PPL Montana.


                  Each of the representations and warranties made by PPL Montana
in Section 3.1 of each of the Participation Agreements, dated as of July 13,
2000 (the "Participation Agreements"), relating to the Lease Transactions is
hereby incorporated herein by reference as if fully set forth herein and shall
be deemed made as of the date hereof and the Closing Date (as defined in Section
3). In addition, PPL Montana further represents and warrants to, and agrees
with, the several Initial Purchasers on and as of the date hereof and the
Closing Date that:

                  (a) Each of the Preliminary Offering Memorandum and the
         Offering Memorandum, as of its respective date, did not, and on the
         Closing Date the Offering Memorandum will not, contain any untrue
         statement of a material fact or omit to state a material fact necessary
         in order to make the statements therein, in the light of the
         circumstances under which they were made, not misleading; provided that
         PPL Montana does not make a representation or warranty as to
         information contained in or omitted from the Preliminary Offering
         Memorandum or the Offering Memorandum in reliance upon and in
         conformity with written information relating to the Initial Purchasers
         furnished to PPL Montana by or on behalf of any Initial Purchaser
         specifically for use therein (the "Initial Purchasers' Information").


                  (b) Each of the Preliminary Offering Memorandum and the
         Offering Memorandum, as of its respective date, contains all of the
         information that, if requested

                                      -2-
<PAGE>   3
         by a prospective purchaser of the Certificates, would be required to be
         provided to such prospective purchaser pursuant to Rule 144A(d)(4)
         under the Securities Act as in effect on the date hereof.

                  (c) Assuming the accuracy of the representations and
         warranties of the Initial Purchasers contained in Section 2 and their
         compliance with the agreements set forth therein, it is not necessary,
         in connection with the issuance and sale of the Certificates to the
         Initial Purchasers and the offer, resale and delivery of the
         Certificates by the Initial Purchasers in the manner contemplated by
         this Agreement and the Offering Memorandum, to register the
         Certificates under the Securities Act or to qualify the Pass Through
         Trust Agreement or the Lease Indentures under the Trust Indenture Act
         of 1939, as amended (the "Trust Indenture Act").

                  (d) PPL Montana and each of its subsidiaries have been duly
         incorporated and are validly existing as limited liability companies in
         good standing under the laws of their respective jurisdictions of
         incorporation, are duly qualified to do business and are in good
         standing as foreign limited liability companies or corporations in each
         jurisdiction in which their respective ownership or lease of property
         or the conduct of their respective businesses requires such
         qualification, and have all power and authority necessary to own or
         hold their respective properties and to conduct the businesses in which
         they are engaged, except where the failure to so qualify or have such
         power or authority would not, singularly or in the aggregate,
         reasonably be expected to have a material adverse effect on the
         condition (financial or otherwise), results of operations, business or
         prospects of PPL Montana and its subsidiaries taken as a whole (a
         "Material Adverse Effect").

                  (e) PPL Montana has a capitalization as of March 31, 2000 as
         set forth in the Offering Memorandum under the heading
         "Capitalization." All of the outstanding membership interests of PPL
         Montana have been duly and validly authorized and issued and are fully
         paid and non-assessable; and all of the membership interests of PPL
         Montana are owned by PPL Montana Holdings, LLC, an indirect wholly
         owned subsidiary of PPL Corporation. All of the outstanding stock,
         partnership, membership or other ownership interests of each subsidiary
         of PPL Montana have been duly and validly authorized and issued, are
         fully paid and non-assessable and are owned directly or indirectly by
         PPL Montana, free and clear of any lien, charge, encumbrance, security
         interest, restriction upon voting or transfer or any other claim of any
         third party.

                  (f) PPL Montana has full right, power and authority to execute
         and deliver this Agreement, the Pass Through Trust Agreement, the
         Registration Rights Agreement and the Participation Agreements
         (collectively, the "Transaction Documents") and to perform its
         obligations hereunder and thereunder. All limited liability company
         action required to be taken for the due and proper authorization,
         execution and delivery of each

                                      -3-
<PAGE>   4
         of the Transaction Documents and the consummation of the transactions
         contemplated thereby have been duly and validly taken.

                  (g) This Agreement has been duly authorized, executed and
         delivered by PPL Montana and constitutes a valid and legally binding
         agreement of PPL Montana enforceable against PPL Montana in accordance
         with its terms, except (i) to the extent that such enforceability may
         be limited by applicable bankruptcy, insolvency, fraudulent conveyance,
         reorganization, moratorium and other similar laws affecting creditors'
         rights generally and by general equitable principles (whether
         considered in a proceeding in equity or at law) and (ii) that any
         rights to indemnity or contribution hereunder may be limited by federal
         and state securities laws and public policy considerations.

                  (h) The Pass Through Trust Agreement has been duly authorized
         by PPL Montana and, when duly executed and delivered in accordance with
         its terms by each of the parties thereto, will constitute a valid and
         legally binding agreement of PPL Montana enforceable against PPL
         Montana in accordance with its terms, except to the extent that such
         enforceability may be limited by applicable bankruptcy, insolvency,
         fraudulent conveyance, reorganization, moratorium and other similar
         laws affecting creditors' rights generally and by general equitable
         principles (whether considered in a proceeding in equity or at law). On
         the Closing Date, the Pass Through Trust Agreement will conform in all
         material respects to the requirements of the Trust Indenture Act and
         the rules and regulations of the Commission applicable to an indenture
         which is qualified thereunder.

                  (i) The Registration Rights Agreement has been duly authorized
         by PPL Montana and, when duly executed and delivered in accordance with
         its terms by each of the parties thereto, will constitute a valid and
         legally binding agreement of PPL Montana enforceable against PPL
         Montana in accordance with its terms, except (i) to the extent that
         such enforceability may be limited by applicable bankruptcy,
         insolvency, fraudulent conveyance, reorganization, moratorium and other
         similar laws affecting creditors' rights generally and by general
         equitable principles (whether considered in a proceeding in equity or
         at law) and (ii) that any rights to indemnity or contribution hereunder
         may be limited by federal and state securities laws and public policy
         considerations.

                  (j) The Certificates have been duly authorized by the Trust
         and, when duly executed, authenticated, issued and delivered as
         provided in the Pass Through Trust Agreement and paid for as provided
         herein, will be duly and validly issued and outstanding and will
         constitute valid and legally binding obligations of the Trust entitled
         to the benefits of the Pass Through Trust Agreement and enforceable
         against the Trust in accordance with its terms, except to the extent
         that such enforceability may be limited by applicable bankruptcy,
         insolvency, fraudulent conveyance, reorganization, moratorium and other
         similar laws affecting creditors' rights generally and by general
         equitable principles (whether considered in a proceeding in equity or
         at law).

                  (k) Each Transaction Document and Operative Document conforms
         in all material respects to the description thereof contained in the
         Offering Memorandum.

                  (l) The execution, delivery and performance by PPL Montana of

         Trustee with the terms thereof, the issuance, authentication, sale and

         the terms thereof, and the consummation of the transactions and the
         granting of the liens contemplated by the Transaction Documents and the
         Operative Documents by each of the parties thereto will not:

                           (i) conflict with or result in a breach or violation
                  of any of the terms or provisions of, or constitute a default
                  under, or result in the creation or imposition of any liens,
                  charge or encumbrance upon any property or assets of PPL
                  Montana or any of its subsidiaries pursuant to, any of the
                  Project Agreements;

                           (ii) conflict with or result in a breach or violation
                  of any of the terms or provisions of, or constitute a default
                  under, or result in the creation or imposition of any lien,
                  charge or encumbrance upon any property or assets of PPL
                  Montana or any of its subsidiaries pursuant to, any material
                  indenture, mortgage, deed of trust, loan agreement or other
                  material agreement or instrument to which PPL Montana or any
                  of its subsidiaries is a party or by which PPL Montana or any
                  of its subsidiaries is bound or to which any of the property
                  or assets of PPL Montana or any of its subsidiaries is
                  subject;

                           (iii) result in any violation of the provisions of
                  the organizational documents of PPL Montana or any of its
                  subsidiaries or any Applicable Law binding on PPL Montana, any
                  of its subsidiaries or any of their properties or assets.

         No consent, approval, authorization or order of, or filing or
         registration with, any court or arbitrator or governmental agency or
         body under any Applicable Law, or any consent, approval, authorization
         or order of, or filing or registration with, any other Person, is
         required for the execution, delivery and performance by PPL Montana of
         each of the Transaction Documents and the consummation of the
         transactions contemplated by the Transaction Documents, except for such
         consents, approvals, authorizations, filings, registrations or
         qualifications (A) which shall have been obtained or made prior to the
         Closing Date which are in full force and effect and not subject to
         appeal, and (B) as may be required to be obtained or made under the
         Securities Act and applicable state securities laws as provided in the
         Registration Rights Agreement.

                  (m) PricewaterhouseCoopers LLP are independent certified
         public accountants with respect to PPL Montana and its subsidiaries
         within the meaning of Rule 101 of the Code of Professional Conduct of
         the American Institute of Certified Public Accountants


                                      -5-

         ("AICPA") and its interpretations and rulings thereunder. The
         historical financial statements (including the related notes) contained
         in the Offering Memorandum comply in all material respects with the
         requirements applicable to a registration statement on Form S-1 under
         the Securities Act (except that certain supporting schedules are
         omitted); and such financial statements have been prepared in
         accordance with generally accepted accounting principles consistently
         applied throughout the periods covered thereby and fairly present the
         financial position of the entities purported to be covered thereby at
         the respective dates indicated and the results of their operations and
         their cash flows for the respective periods indicated. The historical
         financial information contained in the Offering Memorandum under the
         headings "Summary - Summary Consolidated Financial Information and
         Operating Data," "Capitalization," "Selected Financial and Operating
         Data," "Management's Discussion and Analysis of Financial Condition and
         Results of Operations" and "Management - Compensation of Management"
         are derived from the accounting records of PPL Montana and its
         subsidiaries and fairly present the information purported to be shown
         thereby.

                  (n) The financial projections included in Appendix A to the
         Offering Memorandum (the "Projections") have been prepared by R.W. Beck
         and are based upon assumptions which PPL Montana reasonably believes in
         good faith to be 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. PPL Montana believes
         the Projections to be reasonable in light of the assumptions made
         therein. It is agreed and understood that, despite PPL Montana's good
         faith assumptions and reasonable beliefs:

                           (i) 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;

                           (ii) there can be no assurance that the financial
                  results reflected in the Projections will be realized;

                           (iii) the actual results of PPL Montana will differ
                  from the Projections and such differences may be material; and

                           (iv) the Projections are not necessarily indicative
                  of current value or future performance.

                  (o) [Reserved]

                  (p) No action has been taken and no statute, rule, regulation
         or order has been enacted, adopted or issued by any governmental agency
         or body which prevents the issuance of the Certificates or suspends the
         sale of the Certificates in any jurisdiction. No injunction,
         restraining order or order of any nature by any federal or state court
         of

                                      -6-
<PAGE>   7
         competent jurisdiction has been issued with respect to PPL Montana or
         any of its subsidiaries which would prevent or suspend the issuance or
         sale of the Certificates or the use of the Preliminary Offering
         Memorandum or the Offering Memorandum in any jurisdiction. No action,
         suit or proceeding is pending against or, to the best knowledge of PPL
         Montana, threatened against or affecting PPL Montana or any of its
         subsidiaries before any court or arbitrator or any governmental agency,
         body or official, domestic or foreign, which could reasonably be
         expected to interfere with or adversely affect the issuance of the
         Certificates or in any manner draw into question the validity or
         enforceability of any of the Transaction Documents or any action taken
         or to be taken pursuant thereto. PPL Montana has complied with any and
         all requests by any securities authority in any jurisdiction for
         additional information to be included in the Preliminary Offering
         Memorandum and the Offering Memorandum.

                  (q) Neither PPL Montana nor any of its subsidiaries is:

                           (i) in violation of its organizational documents;

                           (ii) in default in any material respect, and no event
                  has occurred which, with notice or lapse of time or both,
                  would constitute such a default, in the due performance or
                  observance of any term, covenant or condition contained in any
                  material indenture, mortgage, deed of trust, loan agreement or
                  other material agreement or instrument to which it is a party
                  or by which it is bound or to which any of its property or
                  assets is subject; or

                           (iii) in violation of any Applicable Law to which it
                  or its property or assets may be subject except where such
                  violation would not have a Material Adverse Effect.

                  (r) PPL Montana and each of its subsidiaries possess all
         material licenses, certificates, authorizations and permits issued by,
         and have made all declarations and filings with, the appropriate
         federal, state or foreign regulatory agencies or bodies which are
         necessary for the ownership of their respective properties or the
         conduct of their respective businesses as described in the Offering
         Memorandum, except where the failure to possess or make the same would
         not, singularly or in the aggregate, have a Material Adverse Effect,
         and neither PPL Montana nor any of its subsidiaries has received
         notification of any revocation or modification of any such license,
         certificate, authorization or permit or has any reason to believe that
         any such license, certificate, authorization or permit will not be
         renewed in the ordinary course.

                  (s) PPL Montana and each of its subsidiaries have filed all
         federal, state, local and foreign income and franchise tax returns
         required to be filed through the date hereof and have paid all taxes
         due thereon, and PPL Montana has not received notice of any tax
         deficiency determined adversely to PPL Montana or any of its
         subsidiaries which has had (nor does PPL Montana or any of its
         subsidiaries have any knowledge of any tax

                                      -7-
<PAGE>   8
         deficiency which, if determined adversely to PPL Montana or any of its
         subsidiaries, could reasonably be expected to have) a Material Adverse
         Effect.

                  (t) Neither PPL Montana nor any of its subsidiaries is
         currently nor will it be, upon the sale of the Certificates in
         accordance herewith and the application of the net proceeds therefrom
         as described in the Offering Memorandum under the caption "Use of
         Proceeds," an "investment company" or a company "controlled by" an
         investment company within the meaning of the Investment Company Act of
         1940, as amended (the "Investment Company Act"), and the rules and
         regulations of the Commission thereunder.

                  (u) PPL Montana is a "subsidiary company" and an "affiliate"

         that is exempt from all provisions of the Holding Company Act, except
         Section 9(a)(2) thereof. The execution, delivery and performance of the

                           (i) transactions are executed in accordance with
                  management's general or specific authorizations;

                           (ii) transactions are recorded as necessary to permit
                  preparation of financial statements in conformity with
                  generally accepted accounting principles and to maintain asset
                  accountability;

                           (iii) access to assets is permitted only in
                  accordance with management's general or specific
                  authorization; and

                           (iv) the recorded accountability for assets is
                  compared with the existing assets at reasonable intervals and
                  appropriate action is taken with respect to any differences.

                  (w) PPL Montana and each of its subsidiaries have insurance
         covering their respective properties, operations, personnel and
         businesses, which insurance is in amounts and insures against such
         losses and risks as are adequate to protect PPL Montana and its
         subsidiaries and their respective businesses. Neither PPL Montana nor
         any of its subsidiaries has received notice from any insurer or agent
         of such insurer that capital improvements or other expenditures are
         required or necessary to be made in order to continue such insurance.

                  (x) PPL Montana and each of its subsidiaries own or possess
         adequate rights to use all material patents, patent applications,
         trademarks, service marks, trade names,

                                      -8-
<PAGE>   9
         trademark registrations, service mark registrations, copyrights,
         licenses and know-how (including trade secrets and other unpatented
         and/or unpatentable proprietary or confidential information, systems or
         procedures) necessary for the conduct of their respective businesses as
         described in the Offering Memorandum; and the conduct of their
         respective businesses does not conflict in any material respect with,
         and neither PPL Montana nor any of its subsidiaries have received any
         notice of any claim of conflict with, any such rights of others.

                  (y) Except as described in the Offering Memorandum, PPL
         Montana and each of its subsidiaries have good and marketable title in
         fee simple to, or have valid rights to lease or otherwise use, all
         items of real and personal property which are material to the business
         of PPL Montana and its subsidiaries, in each case free and clear of all
         liens, encumbrances, claims and defects and imperfections of title
         except such as:

                           (i) do not materially interfere with the use made and
                  proposed to be made of such property by PPL Montana and its
                  subsidiaries; or

                           (ii) could not reasonably be expected to have a
                  Material Adverse Effect.

                  (z) No labor disturbance by or dispute with the employees of
         PPL Montana nor any of its subsidiaries exists or, to the best
         knowledge of PPL Montana, is contemplated or threatened.

                  (aa) No "prohibited transaction" (as defined in Section 406 of
         the Employee Retirement Income Security Act of 1974, as amended,
         including the regulations and published interpretations thereunder
         ("ERISA"), or Section 4975 of the Internal Revenue Code of 1986, as
         amended from time to time (the "Code")) or "accumulated funding
         deficiency" (as defined in Section 302 of ERISA) or any of the events
         set forth in Section 4043(b) of ERISA (other than events with respect
         to which the 30-day notice requirement under Section 4043 of ERISA has
         been waived) has occurred with respect to any employee benefit plan of
         PPL Montana or any of its subsidiaries which could reasonably be
         expected to have a Material Adverse Effect. Each such employee benefit
         plan is in compliance in all material respects with applicable law,
         including ERISA and the Code. PPL Montana and each of its subsidiaries
         have not incurred and do not expect to incur liability under Title IV
         of ERISA with respect to the termination of, or withdrawal from, any
         pension plan for which PPL Montana or any of its subsidiaries would
         have any liability. Each such pension plan that is intended to be
         qualified under Section 401(a) of the Code is so qualified in all
         material respects and nothing has occurred, whether by action or by
         failure to act, which could reasonably be expected to cause the loss of
         such qualification.

                  (bb) Except as described in the Offering Memorandum, there has
         been no storage, generation, transportation, handling, treatment,
         disposal, discharge, emission or

                                      -9-

         other release of any kind, and PPL Montana is not aware of any threat
         of release, of toxic or other wastes or other Hazardous Substances by,
         due to or caused by PPL Montana or any of its subsidiaries (or, to the
         best knowledge of PPL Montana, any other entity (including any
         predecessor) for whose acts or omissions PPL Montana or any of its
         subsidiaries is or could reasonably be expected to be liable) upon any
         of the property now or previously owned or leased by PPL Montana or any
         of its subsidiaries, or upon any other property, in violation of any
         statute or any ordinance, rule, regulation, order, judgment, decree or
         permit or which would, under any statute or any ordinance, rule
         (including rule of common law), regulation, order, judgment, decree or
         permit, give rise to any liability (including with respect to any
         personal injury or property damage claim), except for any violation or
         liability which could not reasonably be expected to have, singularly or
         in the aggregate with all such violations and liabilities, a Material
         Adverse Effect. Except as described in the Offering Memorandum, there
         has been no disposal, discharge, emission or other release of any kind
         onto such property or into the environment surrounding such property of
         any toxic or other wastes or other Hazardous Substances with respect to
         which PPL Montana has knowledge, except for any such disposal,
         discharge, emission or other release of any kind which could not
         reasonably be expected to have, singularly or in the aggregate with all
         such discharges and other releases, a Material Adverse Effect.

                  (cc) Neither PPL Montana, its subsidiaries nor, to the best
         knowledge of PPL Montana, any member, manager, officer, agent, employee
         or other person associated with or acting on its or their behalf has:

                           (i) used any corporate funds for any unlawful
                  contribution, gift, entertainment or other unlawful expense
                  relating to political activity;

                           (ii) made any direct or indirect unlawful payment to
                  any foreign or domestic government official or employee from
                  corporate funds;

                           (iii) violated or is in violation of any provision of
                  the Foreign Corrupt Practices Act of 1977; or

                           (iv) made any bribe, rebate, payoff, influence
                  payment, kickback or other unlawful payment.

                  (dd) PPL Montana has no reason to believe that 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 incomplete or incorrect in any material respect.

         no outstanding subscriptions, rights, warrants, calls or options to
         acquire, or instruments convertible into or exchangeable for, or

         Certificates will be used, directly or indirectly, for the purpose of
         purchasing or carrying any margin security, for the purpose of reducing
         or retiring any indebtedness which was originally incurred to purchase
         or carry any margin security or for any other purpose which might cause
         any of the Certificates to be considered a "purpose credit" within the
         meanings of Regulation G, T, U or X of the Federal Reserve Board.

                  (hh) Except for any fees to be paid by PPL Montana to the
         Initial Purchasers in connection with the offering of the Certificates,
         neither PPL Montana nor any of its subsidiaries is a party to any
         contract, agreement or understanding with any person that would give

         a brokerage commission, finder's fee or like payment in connection with
         the offering and sale of the Certificates.

                  (ii) The Certificates satisfy the eligibility requirements of
         Rule 144A(d)(3) under the Securities Act.

                  private sale exempt from registration under the Securities
                  Act;

                  Institutional Buyers") as defined in Rule 144A under the
                  Securities Act, or if any such person is buying for one or
                  more institutional accounts for which such person is acting as
                  fiduciary or agent, only when such person has represented to
                  it that each such account is a Qualified Institutional Buyer

                  transactions in accordance with Rule 144A (y) in accordance
                  with Rule 903 under the Securities Act or (z) to a limited
                  number of Institutional Accredited Investors (as defined
                  below) in accordance with clause (c) below.

         Accordingly, neither the Initial Purchasers nor their respective
         affiliates, nor any persons acting on their behalf, have engaged or
         will engage in any directed selling efforts with respect to the
         Securities, and the Initial Purchasers, their respective affiliates and
         all persons acting on their behalf have complied and will comply with
         the offering restrictions requirement of Regulation S. Each Initial
         Purchaser agrees that, at or prior to confirmation of sale of the
         Securities, other than a sale pursuant to Rule 144A or a sale to an
         Institutional Accredited Investor in accordance with clause (c) below,

         concession, fee or other remuneration that purchases the Securities
         from it 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 or 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 date 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 meanings given to them by
                  Regulation S."

         Terms used in this subsection (b) have the meanings given to them by
         Regulations S.

         Each Initial Purchaser, severally and not jointly, agrees that, prior
         to or simultaneously with the confirmation of sale by such Initial
         Purchaser to any purchaser of any of the Certificates purchased by such
         Initial Purchaser from the Trust pursuant hereto, such Initial
         Purchaser shall furnish to that purchaser a copy of the Offering
         Memorandum (and any amendment or supplement thereto that PPL Montana
         shall have furnished to such Initial Purchaser prior to the date of
         such confirmation of sale). In addition to the foregoing, each Initial
         Purchaser acknowledges and agrees that PPL Montana (and, for purposes
         of the opinions to be delivered to the Initial Purchasers pursuant to
         Sections 5(e) and (f), counsel for PPL Montana and for the Initial
         Purchasers) may rely upon the accuracy of the representations and
         warranties of the Initial Purchasers and their compliance with their
         agreements contained in this Section 2, and each Initial Purchaser
         hereby consents to such reliance.

                  (c) The Initial Purchasers may offer and sell Certificates in
         definitive, fully registered form to a limited number of institutions,
         each of which is reasonably believed by such Initial Purchaser to be an
         "accredited investor" within the meaning of Rule 501(a)(1), (2), (3) or
         (7) under the Securities Act or an entity in which all of the equity
         owners are accredited investors within the meaning of Rule 501(a)(1),
         (2), (3) or (7) under the Securities Act (each, an "Institutional
         Accredited Investor"); provided that each such Institutional Accredited
         Investor executes and delivers to the Initial Purchasers and PPL
         Montana, prior to the consummation of any sale of Certificates to such
         Institutional Accredited Investor, a Purchaser's Letter in

                  3. Delivery of and Payment for the Certificates.


                  (a) Delivery of and payment for the Certificates shall be made
         at the offices of Orrick, Herrington & Sutcliffe LLP, 666 Fifth Avenue,
         New York, New York 10103, or at such other place as shall be agreed
         upon by the Initial Purchasers and PPL Montana, at 10:00 A.M., New York
         City time, on July 20, 2000, or at such other time or date, not later
         than seven full business days thereafter, as shall be agreed upon by
         the Initial Purchasers and PPL Montana (such date and time of payment
         and delivery being referred to herein as the "Closing Date").

                  (b) On the Closing Date, payment of the purchase price for the
         Certificates shall be made to the Trust by wire or book-entry transfer
         of same-day funds to such account or accounts as PPL Montana and the
         Pass Through Trustee shall specify prior to the Closing Date or by such
         other means as the parties hereto shall agree prior to the Closing Date
         against delivery to the Initial Purchasers of the certificates
         evidencing the Certificates. Time shall be of the essence, and delivery
         at the time and place specified pursuant to this Agreement is a further
         condition of the obligations of the Initial Purchasers hereunder. Upon
         delivery, the Certificates sold by the Initial Purchasers (i) to
         Qualified Institutional Buyers and in reliance on Rule 903 under the
         Securities Act shall be in global form, registered in such names and in
         such denominations as CSI (on behalf of the Initial Purchasers) shall
         have requested in writing not less than two full business days prior to
         the Closing Date and (ii) to Institutional Accredited Investors shall
         be in definitive form, registered in such names and in such
         denominations as CSI (on behalf of the Initial Purchasers) shall have
         requested in writing not less than two full business days prior to the
         Closing Date. PPL Montana agrees to make one or more global and
         definitive certificates evidencing the Certificates available for
         inspection by CSI on behalf of the Initial Purchasers in New York, New
         York at least 24 hours prior to the Closing Date.

                  4. Further Agreements of PPL Montana.

                  PPL Montana agrees with each of the several Initial
         Purchasers:

                  (a) to advise the Initial Purchasers promptly and, if
         requested, confirm such advice in writing, of the happening of any
         event which makes any statement of a material fact made in the Offering
         Memorandum untrue or which requires the making of any additions to or
         changes in the Offering Memorandum (as amended or supplemented from
         time to time) in order to make the statements therein, in the light of
         the circumstances under which they were made, not misleading; to advise
         the Initial Purchasers promptly of any order preventing or suspending
         the use of the Preliminary Offering Memorandum or the Offering
         Memorandum, of any suspension of the qualification of the Certificates
         for offering or sale in any jurisdiction and of the initiation or
         threatening of any proceeding for any such purpose; and to use its best
         efforts to prevent the issuance of any such order preventing or
         suspending the use of the Preliminary Offering Memorandum or the


                                      -15-
<PAGE>   16

                  (c) prior to making any amendment or supplement to the
         Offering Memorandum, to furnish a copy thereof to each of the Initial
         Purchasers and counsel for the Initial Purchasers and not to effect any
         such amendment or supplement to which the Initial Purchasers shall
         reasonably object by notice to PPL Montana after a reasonable period to
         review;

                  (d) if, at any time prior to completion of the resale of the
         Certificates by the Initial Purchasers, any event shall occur or
         condition exist as a result of which it is necessary, in the opinion of
         counsel for the Initial Purchasers or counsel for PPL Montana, to amend
         or supplement the Offering Memorandum in order that the Offering
         Memorandum will not include an untrue statement of a material fact or
         omit to state a material fact necessary in order to make the statements
         therein, in the light of the circumstances existing at the time it is
         delivered to a purchaser, not misleading, or if it is necessary to
         amend or supplement the Offering Memorandum to comply with applicable
         law, to promptly prepare such amendment or supplement as may be
         necessary to correct such untrue statement or omission or so that the
         Offering Memorandum, as so amended or supplemented, will comply with
         applicable law, and the Initial Purchasers' delivery to offerees or
         investors of any such amendment or supplement shall not constitute a
         waiver of any of the conditions set forth in Section 5 hereof;

                  (e) for so long as the Certificates are outstanding and are
         "restricted securities" within the meaning of Rule 144(a)(3) under the

         the Securities Act, unless PPL Montana is then subject to and in
         compliance with Section 13 or 15(d) of the Exchange Act (the foregoing
         agreement being for the benefit of the holders from time to time of the
         Certificates and prospective purchasers of the Certificates designated
         by such holders);

                  (f) for so long as the Certificates are outstanding, to
         furnish to the Initial Purchasers copies of any annual reports,
         quarterly reports and current reports filed by PPL Montana with the

         may be designated by the Commission, and such other documents, reports

         Initial Purchasers may reasonably request to qualify the Certificates
         for offering and sale under the securities or Blue Sky laws of such

         offer, sell, contract to sell or otherwise dispose of, directly or
         indirectly, any securities under circumstances where such offer, sale,

         and sale of the Certificates as contemplated by this Agreement and the
         Offering Memorandum;

         transaction registered under the Securities Act;

                  Offering Memorandum;

                           (ii) in their opinion, the Offering Memorandum, as of
                  its date, (excluding Appendices A, B and C thereto) did not

                  which they were made, not misleading, and since the date of
                  the Offering Memorandum, no event has occurred which should
                  have been set forth in a supplement or amendment to the
                  Offering Memorandum so that the Offering Memorandum (as so
                  amended or supplemented) would not include any untrue
                  statement of a material fact and would not omit to state a
                  material fact required to be stated therein or necessary in

                  circumstances under which they were made, not misleading;

                           (iii) as of the Closing Date, the representations and
                  warranties of PPL Montana in this Agreement (including the
                  representations and warranties of PPL Montana in the
                  Participation Agreement which have been incorporated by
                  reference herein) are true and correct in all material
                  respects, PPL Montana has complied with all agreements and
                  satisfied all conditions on its part to be performed or
                  satisfied hereunder on or prior to the Closing Date, and
                  subsequent to the date as of which information is given in the

                  thereto), there has been no material adverse change in the
                  financial position or results of operation of PPL Montana or
                  any of its subsidiaries, or any change, or any development
                  including a prospective change, in or affecting the condition
                  (financial or otherwise), results of operations or business of
                  PPL Montana and its subsidiaries taken as a whole, except as
                  set forth in the Offering Memorandum;

                           (iv) in their opinion, the Projections prepared by
                  R.W. 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-
<PAGE>   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.

                  (k) The Initial Purchasers shall have received a counterpart
         of the Registration Rights Agreement which shall have been executed and
         delivered by a duly authorized officer of PPL Montana.

                  (l) The Pass Through Trust Agreement shall have been duly
         executed and delivered by PPL Montana and the Pass Through Trustee, and
         the Certificates shall have been duly executed, delivered and
         authenticated in accordance with the Pass Through Trust Agreement.

                  (m) If any event shall have occurred prior to the Closing Date
         that requires PPL Montana under Section 4(d) to prepare an amendment or
         supplement to the Offering Memorandum, such amendment or supplement
         shall have been prepared, the Initial Purchasers shall have been given
         a reasonable opportunity to comment thereon, and copies thereof shall
         have been delivered to the Initial Purchasers reasonably in advance of
         the Closing Date.

                  (n) There shall not have occurred any invalidation of Rule
         144A under the Securities Act by any court or any withdrawal or
         proposed withdrawal of any rule or regulation under the Securities Act
         or the Exchange Act by the Commission or any amendment or proposed
         amendment thereof by the Commission which in the judgment of the
         Initial Purchasers would materially impair the ability of the Initial
         Purchasers to purchase, hold or effect resales of the Certificates as
         contemplated hereby.

                  (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-
<PAGE>   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.

                  (q) The Equity Contribution Agreement related to each Lease
         Transaction among PPL Corporation, PPL Montana and the applicable Lease
         Indenture Trustee shall have been duly authorized, executed and
         delivered by the parties thereto and shall be in full force and effect.

                  (r) Subsequent to the execution and delivery of this
         Agreement:

                           (i) no downgrading shall have occurred in the rating
                  accorded the Certificates or PPL Montana's debt securities or
                  preferred stock by any "nationally recognized statistical
                  rating organization," as such term is defined by the
                  Commission for purposes of Rule 436(g)(2) of the rules and
                  regulations of the Commission under the Securities Act; and

                           (ii) no such organization shall have publicly
                  announced that it has under surveillance or review (other than
                  an announcement with positive implications of a possible
                  upgrading), its rating of the Certificates or PPL Montana's
                  debt securities or preferred stock.

                  (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-
<PAGE>   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.

                  (u) Subsequent to the execution and delivery of this
         Agreement, S&P shall have delivered to PPL Montana (a copy of which
         shall be delivered to the Initial Purchasers) a final rating letter,
         setting forth a rating of not less than BBB with respect to the
         Certificates, (B) Moody's shall have delivered to PPL Montana (a copy
         of which shall be delivered to the Initial Purchasers) a final rating
         letter, setting forth a rating of not less than Baa3 with respect to
         the Certificates and (C) Fitch shall have delivered to PPL Montana (a
         copy of which shall be delivered to the Initial Purchasers) a final
         rating letter, setting forth a rating of not less than BBB with respect
         to the Certificates.

                  (v) Each of the Independent Market Consultant, the Independent
         Fuel Consultant and the Independent Engineer shall have delivered to
         the Initial Purchasers a letter reaffirming the accuracy and
         completeness, as of the Closing Date, of the conclusions and findings
         of such firm contained in its final report in the Offering Memorandum.

                  (w) PPL Montana shall have furnished to the Initial
         Purchasers:

                           (i) a copy of the resolutions, certified by the
                  Secretary or Assistant Secretary of PPL Montana as of the
                  Closing Date, duly authorizing the execution, delivery and
                  performance of the Transaction Documents and each other
                  Operative Document to which it is a party and any other
                  documents to be executed on or prior to the Closing Date by or
                  on behalf of it in connection with the transactions
                  contemplated thereby;


                                      -24-
<PAGE>   25
                           (ii) certified copies of its organizational
                  documents; and

                           (iii) certified copies of powers-of-attorney, if any,
                  pursuant to which officers of PPL Montana shall execute the
                  Transaction Documents and each other document relating to the
                  Lease Transactions to which it is a party and any other
                  documents executed by or on behalf of it in connection with
                  the transactions contemplated thereby.

         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-
<PAGE>   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-
<PAGE>   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-
<PAGE>   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-
<PAGE>   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-
<PAGE>   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. Expenses.

                                    ANNEX B

                   [Form of Opinion of PPL Montana's Counsel]


         Counsel to PPL Montana shall have furnished to the Initial Purchasers
their written opinion, as counsel to PPL Montana, addressed to the Initial
Purchasers and dated the Closing Date, in form and substance reasonably
satisfactory to the Initial Purchasers, substantially to the effect set forth
below:

         (i) Each of PPL Montana and each of its subsidiaries has been duly
formed or incorporated and is validly existing as a limited liability company or
corporation in good standing under the laws of the jurisdiction of its
incorporation, is duly qualified to do business and is in good standing as a
foreign limited liability company or corporation in each jurisdiction in which
its respective ownership or lease of property or the conduct of its businesses
requires such qualification, and has all power and authority necessary to own or
hold its properties and to conduct the businesses in which it is engaged (except
where the failure to so qualify or have such power or authority would not,
singularly or in the aggregate, reasonably be expected to have a Material
Adverse Effect);

         (ii) PPL Montana has a capitalization as of March 31, 2000 as set forth
in the Offering Memorandum under the heading "Capitalization", and all of the
outstanding membership interests in PPL Montana have been duly and validly
authorized and issued and are fully paid and non-assessable; and all of the
membership interests in PPL Montana are owned by PPL Montana Holdings, LLC, an
indirect wholly-owned subsidiary of PPL Corporation;

         (iii) the descriptions in the Offering Memorandum of statutes, legal
and governmental proceedings and contracts and other documents are accurate in
all material respects; the statements in the Offering Memorandum under the
headings "Material U.S. Federal Income Tax Considerations" and "ERISA
Considerations," to the extent that they constitute summaries of matters of law
or regulation or legal conclusions, have been reviewed by such counsel and
fairly summarize the matters described therein in all material respects; and
such counsel does not have actual knowledge of any current or pending legal or
governmental actions, suits or proceedings which would be required to be
described in the Offering Memorandum if the Offering Memorandum were a
prospectus included in a registration statement on Form S-1 which are not
described as so required;

         (iv) the Pass Through Trust Agreement conforms in all material respects
with the requirements of the Trust Indenture Act and the rules and regulations
of the Commission applicable to an indenture which is qualified thereunder;

         (v) PPL Montana has full right, power and authority to execute and
deliver each of the Transaction Documents and to perform its obligations
thereunder; and all limited liability company action required to be taken for
the due and proper authorization, execution and delivery of

                                       i
<PAGE>   39
each of the Transaction Documents and the consummation of the transactions
contemplated thereby have been duly and validly taken;

         (vi) each of the Purchase Agreement and the Registration Rights
Agreement has been duly authorized, executed and delivered by PPL Montana and
constitutes a valid and legally binding agreement of PPL Montana enforceable
against PPL Montana in accordance with its terms, except to the extent that such
enforceability may be limited by applicable bankruptcy, insolvency, fraudulent
conveyance, reorganization, moratorium and other similar laws affecting
creditors' rights generally and by general equitable principles (whether
considered in a proceeding in equity or at law) and except to the extent that
the indemnification provisions thereof may be unenforceable;

         (vii) the Pass Through Trust Agreement has been duly authorized,
executed and delivered by PPL Montana and, assuming due authorization, execution
and delivery thereof by the Pass Through Trustee, constitutes a valid and
legally binding agreement of PPL Montana enforceable against PPL Montana in
accordance with its terms, except to the extent that such enforceability may be
limited by applicable bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium and other similar laws affecting creditors' rights
generally and by general equitable principles (whether considered in a
proceeding in equity or at law);

         (viii) the Certificates have been duly authorized and issued by the
Trust and, assuming due authentication thereof by the Pass Through Trustee and
upon payment and delivery in accordance with the Purchase Agreement, will
constitute valid and legally binding obligations of the Trust entitled to the
benefits of the Pass Through Trust Agreement and enforceable against the Trust
in accordance with their terms, except to the extent that such enforceability

conferences with representatives of PPL Montana, representatives of its
independent accountants and counsel and representatives of the Initial
Purchasers and their counsel at which conferences the contents of the
Preliminary Offering Memorandum and the Offering Memorandum and any amendment or
supplement thereto and related matters were discussed and, although such counsel
assumes no responsibility for the accuracy, completeness or fairness of the
Offering Memorandum or any amendment or supplement thereto (except as expressly
provided above), nothing has come to the attention of such counsel to cause such
counsel to believe that the Offering Memorandum or any amendment or supplement
thereto (other than the financial statements and other financial and statistical
information contained therein, as to which such counsel may express no belief),
as of the date thereof and as of the Closing Date, contained or contains any
untrue statement of a material fact or omitted 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 may rely as to matters of fact,
to the extent such counsel deems proper, on certificates of responsible officers
of PPL Montana and public officials which are furnished to the Initial
Purchasers.

                        [Form of Initial Comfort Letter]


         PPL Montana shall have furnished to the Initial Purchasers a letter of
PricewaterhouseCoopers LLP addressed to the Initial Purchasers and dated the
date of the Purchase Agreement, in form and substance satisfactory to the
Initial Purchasers, substantially to the effect set forth below:

         (i) they are independent certified public accountants with respect to
PPL Montana within the meaning of Rule 101 of the Code of Professional Conduct
of the AICPA and its interpretations and rulings;

         (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
<PAGE>   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.

Ladies and Gentlemen:

         In connection with our proposed purchase of Pass Through Certificates
(the "Certificates") evidencing a fractional undivided interest in a trust, the
property of which consists of certain notes secured by certain property leased
to PPL Montana, LLC ("PPL Montana"), we confirm that:

                  1. We have received a copy of the offering memorandum (the
         "Offering Memorandum") relating to the Certificates and such other
         information as we deem necessary in order to make our investment
         decision. We acknowledge that we have read and agree to the matters
         stated under the captions "Transfer Restrictions" and "Plan of
         Distribution" in such Offering Memorandum, and the restrictions on
         duplication and circulation of such Offering Memorandum.

                  2. We understand that any subsequent transfer of the
         Certificates is subject to certain restrictions and conditions set
         forth in the Pass Through Trust Agreement (the "Pass Through Trust
         Agreement") relating to the Certificates and conditions set forth under
         "Transfer Restrictions" and "Plan of Distribution" and we agree to be
         bound by, and not to resell, pledge or otherwise transfer the
         Certificates except in compliance with such restrictions and conditions
         and the Securities Act of 1933, as amended (the "Securities Act").

                  3. We understand that the offer and sale of the Certificates
         has not been registered under the Securities Act, and that the
         Certificates may not be offered or sold except as permitted in the
         following sentence. We agree, on our own behalf and on behalf of any
         accounts for which we are acting as hereinafter stated, that if we
         should sell any Certificates within the time period referred to in Rule
         144(k) of the Securities Act, we will do so only (A) to PPL Montana or
         any subsidiary thereof, (B) in accordance with Rule 144A under the
         Securities Act to a "qualified institutional buyer" (as defined
         therein), (C) to an institutional "accredited investor" (as defined
         below) that, prior to such transfer, furnishes to the Pass Through
         Trustee a signed letter containing certain representations and
         agreements relating to the restrictions on transfer of the Certificates
         (the form of which letter can be obtained from the Pass Through
         Trustee) and, if such transfer is in respect of an aggregate principal
         amount at the time of transfer of Certificates of less than $100,000,
         an opinion of counsel acceptable to PPL Montana that such transfer is
         in compliance with the Securities Act, (D) outside the United States in
         accordance with Rule 904 of Regulation S under the Securities Act, (E)
         pursuant to the exemption from registration provided by Rule 144 under
         the Securities Act (if available), or (F) pursuant to an effective
         registration statement under the Securities Act, and we further agree
         to provide to any person purchasing any of the Certificates from us a
         notice advising such purchaser that resales of the Certificates are
         restricted as stated herein.
<PAGE>   45
                  4. We are an institutional "accredited investor" (as defined
         in Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities
         Act) and have such knowledge and experience in financial and business
         matters as to be capable of evaluating the merits and risks of our
         investment in the Certificates, and we and any accounts for which we
         are acting are each able to bear the economic risk of our or its
         investment.

                  5. We are acquiring the Certificates purchased by us for our
         own account or for one or more accounts (each of which is an
         institutional "accredited investor") as to each of which we exercise
         sole investment discretion.

                  6. We are not acquiring the Certificates with a view to
         distribution thereof or with any present intention of offering or
         selling any Certificates, except as permitted above; provided, that the
         disposition of our property and property of any accounts for which we
         are acting as fiduciary will remain at all times within our control.

         You, PPL Montana and the Pass Through Trustee are entitled to rely upon
this letter and are irrevocably authorized to produce this letter or a copy
hereof to any interested party in any administrative or legal proceedings or
official inquiry with respect to the matters covered hereby.



                                     Very truly yours,



                                     By:
