                           NON COLSTRIP UNIT NUMBER 3
                     WHOLESALE TRANSITION SERVICE AGREEMENT

         This Wholesale Transition Service Agreement (this "Agreement") is
entered into effective as of the day of the 17th day of December, 1999 (the
"Effective Date"), by and between PP&L MONTANA, LLC, a Delaware limited
liability company, ("Seller" or "PP&L"), and THE MONTANA POWER COMPANY, a
Montana corporation ("Buyer" or "MPC"). Seller and Buyer are also referred to
herein individually as a "Party" and collectively as the "Parties."

         1. Under the Asset Purchase Agreement, defined below, MPC has sold its
generating facilities and/or power purchase/exchange agreements and related
assets to PP&L Global, Inc. PP&L Global, Inc. has assigned its interest to PP&L.

         2. MPC must still provide power to its wholesale and retail customers
who have not yet chosen an alternative power supplier or who have not yet been
given the opportunity to choose an alternative power supplier.

         3. Since MPC will not own any generating facility and/or power
purchase/exchange contracts to serve these customers, MPC must contract with
PP&L to serve, in part, MPC's remaining wholesale and retail customer loads.

         4. MPC and PP&L enter into this Agreement to allow MPC to purchase and
PP&L to sell defined quantities of power from the generating facilities and/or
power purchase/exchange contracts.

         5. Since MPC must rely on the Seller to serve a portion of the
remaining wholesale and retail customer load, MPC and PP&L intend that PP&L's
delivery obligation is absolute and will not be excused for any reason.

         In consideration of the Parties' mutual promises, they agree as
follows:

deliver, or cause to be delivered, and Buyer shall purchase and receive, or
cause to be received, an amount of firm energy measured in mWh per hour equal to
the Seller's proportional allocation of Buyer's actual Remaining Customer Load.
An initial non-binding estimate of the Seller's share of the Buyer's Remaining
Load Obligation can be computed by multiplying the initial estimate of the
Remaining Customer Load shown in Exhibit D by the appropriate Proportional
Allocation Factor in Exhibit C. The Proportional Allocation Factor defined in
Exhibit C assumes the same Closing Date, which will be defined, for all assets
and power purchase agreements. The Proportional Allocation Factor may change if
the generation asset and contract sale results in multiple Closing Dates, or a
different mix of resources available to serve the Remaining Customer Load.
Seller's obligation to deliver, or cause to be delivered, the Contract Quantity

amount for each kWh of such deficiency equal to the positive difference, if any,
obtained by subtracting the Replacement Price for the deficient Contract
Quantity from the Energy Charge, plus twenty percent (20%) of the resulting
amount. "Replacement Price" means the price at which Seller, acting in a
commercially reasonable manner, sells the deficiency energy not received by
Buyer (plus additional transmission charges, if any, incurred by Seller to the
Delivery Point) or, absent a purchase, the market price for such quantity of
energy at such Delivery Point as determined by Seller in a commercially
reasonable manner; provided, however, in no event shall the Replacement Price
include any penalties, ratcheted demand or similar charges.

         4.4 ACKNOWLEDGMENT OF THE PARTIES. The Parties stipulate that the
payment obligations set forth in this Article 4 are reasonable in light of the

              EVENTS OF DEFAULT, REMEDIES AND REGULATORY APPROVALS

         9.1 EVENTS OF DEFAULT. An "Event of Default" means, with respect to a
Party alleged to have taken or been affected by any of the actions set forth
below in this Section 9.1 (the "Defaulting Party"):

                  (a) the failure by the Defaulting Party to make, when due, any
payment required under this Agreement if such failure is not remedied within
five (5) Work Days after written notice of such failure is given to the
Defaulting Party by the other Party ("Non-Defaulting Party"), provided that the
payment is not the subject of a good faith dispute as described in the billing
and payment provisions under Article 10; or

                  (b) any representation or warranty made by the Defaulting
Party in this Agreement shall prove to have been false or misleading in any
material respect when made or ceases to remain true during the Contract Term; or

                  (c) the failure by the Defaulting Party to perform any
covenant set forth in this Agreement (other than the events that are otherwise
specifically covered in this Section 9.1 as a separate Event of Default or
Seller's obligation to sell and deliver, and Buyer's obligation to purchase and
receive, for which a separate remedy is provided in Article 4), and such failure
is not cured within five (5) Work Days after written notice thereof to the
Defaulting Party; or

                  (d) the Defaulting Party shall make an assignment (other than
any assignment permitted pursuant to Article 11) or any general arrangement for
the benefit of creditors;

                  (e) the Defaulting Party shall file a petition or otherwise
commence, authorize or acquiesce in the commencement of a proceeding or cause of
action under any bankruptcy or similar law for the protection of creditors, or
have such petition filed against it and such petition is not withdrawn or
dismissed within thirty (30) days after such filing;

                  (f) the Defaulting Party shall otherwise become bankrupt or
insolvent (however evidenced); or

                  (g) the Defaulting Party shall be unable to pay its debts as
they fall due;

                  (h) the guarantor of the Defaulting Party fails to perform any
covenant set forth in the guaranty agreement it delivered in respect of this
Agreement (if any), any representation or warranty made by such guarantor in the
guaranty agreement


                                       12
MPC NON COLSTRIP 3
   13
shall prove to have been false or misleading in any material respect when made
or when deemed to be repeated or such guarantor shall take or suffer any actions
set forth in Section 9.1 (d) as applied to it; or

                  (i) guarantor of the Defaulting Party shall repudiate, purport
to revoke or fail to perform any of such guarantor's obligations under such
guarantor's guaranty hereunder, or guarantor shall cease to exist; or

                  (j) if at any time, in the case of: (i) Buyer, Buyer shall
have defaulted on its indebtedness to third parties resulting in obligations
(whether individually or in the aggregate) of Buyer in excess of Twenty Five
Million U.S. Dollars ($25,000,000), becoming, or becoming capable of being
declared, accelerated; or (ii) Seller, Seller shall have defaulted on its
indebtedness to third parties resulting in obligations of Seller in excess of
Twenty Five Million U.S. Dollars ($25,000,000), becoming, or becoming capable of
being declared, accelerated.

         9.2 REMEDIES UPON AN EVENT OF DEFAULT.

                  (a) If an Event of Default occurs with respect to a Defaulting
Party at any time during the Contract Term, the Non-Defaulting Party may, for so
long as the Event of Default is continuing (i) establish a date (which date
shall be between five (5) and ten (10) Work Days after the Non-Defaulting Party
delivers notice) ("Early Termination Date") on which this Agreement shall
terminate if the Event of Default has not been cured and (ii) withhold any
payments due in respect of this Agreement; provided, however, upon the
occurrence of any Event of Default listed in Section 9.1(d) as it may apply to
any Party, this Agreement shall automatically terminate, without notice, and
without any other action by either Party as if an Early Termination Date had
been declared immediately prior to such event. If an Early Termination Date has
been designated, the Non-Defaulting Party shall in good faith calculate its
Gains or Losses and Costs (as hereafter defined) resulting from the termination
of this Agreement. The Gains, Losses and Costs shall be determined by comparing
the value of the remaining Contract Term and Contract Quantity under this
Agreement had it not been terminated to the equivalent quantities and relevant
market prices for the remaining term either quoted by a bona fide third-party
offer or which are reasonably expected to be available in the market under a
replacement contract for this Agreement. To ascertain the market prices of a
replacement contract, the Non-Defaulting Party may consider, among other
valuations, any or all of the settlement prices of NYMEX electricity futures
contracts, quotations from leading dealers in energy swap contracts and other
bona fide third party offers, all adjusted for the length of the remaining term
and differences in transmission. It is expressly agreed that a Party shall not
be required to enter into a replacement transaction in order to determine the
Termination Payment (as hereafter defined). The Non-Defaulting Party shall
aggregate such Gains, Losses and Costs with respect to this Agreement into a
single net amount ("Termination Payment") and notify the Defaulting Party. If
the Non-Defaulting Party's aggregate Losses and Costs exceed


                                       13
MPC NON COLSTRIP 3
   14
its aggregate Gains, the Defaulting Party shall, within five (5) Work Days of
receipt of such notice, pay the net amount to the Non-Defaulting Party, which
amount shall bear interest at the Interest Rate from the Early Termination Date
until paid. If the Non-Defaulting Party's aggregate Gains exceed its aggregate
Losses and Costs, if any, resulting from the termination of this Agreement, the
amount of the Termination Payment shall be zero. If the Defaulting Party
disagrees with the calculation of the Termination Payment, the issue shall be
submitted to binding arbitration in accordance with the arbitration procedures
set forth in Section 16.9 and the resulting Termination Payment shall be due and
payable within ten (10) Work Days after the award.

                  (b)      For purposes of this Agreement:

                  "Costs" mean(s), with respect to a Party, brokerage fees,
commissions and other similar transaction costs and expenses, including, without
limitation, verifiable breakage costs, reasonably incurred by such Party either
in terminating any arrangement pursuant to which it has hedged its obligations
or entering into new arrangements which replace this Agreement and attorneys'
fees, if any, incurred in connection with enforcing its rights under this
Agreement.

                  "Gains" mean(s), with respect to a Party, an amount equal to
the present value of the economic benefit (exclusive of Costs), if any, to such
Party resulting from the termination of its obligations with respect to this
Agreement determined in a commercially reasonable manner.

                  "Losses" mean(s), with respect to a Party, an amount equal to
the present value of the economic loss (exclusive of Costs), if any, to such
Party resulting from the termination of its obligations with respect to this
Agreement determined in a commercially reasonable manner.

                  In no event, however, shall a Party's Gains, Losses or Costs
include any penalties, ratcheted demand or similar charges. At the time for
payment of any amount due under this Section 9.2, each Party shall pay to the
other Party all additional amounts payable by it pursuant to this Agreement, but
all such amounts shall be netted and aggregated with any Termination Payment
payable hereunder.

         9.3 OTHER EVENTS. Except with respect to the initial regulatory
approvals provided for in Section 9.4, in the event that either Party is
regulated by a federal, state or local regulatory body, and such body shall
subsequently disallow all or any portion of any costs incurred or yet to be
incurred by such Party under any provision of this Agreement, such action shall
not operate to excuse such Party from performance of any obligation nor shall
such action give rise to any right of such Party to any retroactive adjustment
of the Energy Charge. Despite the foregoing, if a Party's activities hereunder
become subject to regulation of any kind whatsoever under any law (other than
with respect to Transition Costs) to a greater or different extent than that


                                       14
MPC NON COLSTRIP 3

   15
existing on the Effective Date and such regulation either (a) renders all of
this Agreement illegal or unenforceable or (b) materially adversely affects the
business of a Party, with respect to its financial position or otherwise, then
in the case of (a) above, either Party, and in the case of (b) above, only the
Party affected (for purposes of this Section 9.3, the "Defaulting Party"), shall
at such time have the right to declare an Early Termination Date in accordance
with the provisions hereof; provided that notwithstanding the rights of the
Parties to declare an Early Termination Date as above stated, the Defaulting
Party shall be liable for payment of the Termination Payment calculated by the
Non-Defaulting Party as provided in Section 9.2.

         9.4 REGULATORY APPROVALS. The Seller shall file this Agreement with
FERC. The obligations of the Parties under this Agreement are subject to and
contingent upon receipt and approval by each Party (in each Party's sole
discretion) of an order of FERC accepting this Agreement for filing or otherwise
permitting this Agreement to be or become effective, including, without
limitation, rates to be charged hereunder. If the FERC or any reviewing court or
other governmental agency, including, without limitation, the Montana Public
Service Commission, imposes any condition, limitation or qualification upon this
Agreement or upon the performance by either of the Parties of its performance
hereunder which, individually or in the aggregate, precludes either or both of
the Parties from performing, in whole or in part, this Agreement, or materially
adversely affects the benefits of this Agreement to either Party, then the
precluded or affected Party may terminate this Agreement by giving, within not
less than thirty (30) days of the entry of any such order or decree, written
notice thereof to the other Party, effective as of the date of entry of the
applicable order or decree imposing such condition, limitation or qualification.
In no event shall the terminating Party incur any liability (whether for lost
revenues or lost profits or otherwise) as a result of such termination.

                               BILLING AND PAYMENT

         10.1 BILLING AND PAYMENT. Seller shall render to Buyer (by regular
mail, facsimile or other acceptable means pursuant to Article 14) for each
calendar month during the Delivery Term a statement setting forth the total
Energy Charges for the month and any other charges due Seller, including,
without limitation, any payment due pursuant to Article 4 during the preceding
month. Billing and payment will be based on the Energy Charge and on Scheduled
hourly quantities. Payment by Buyer shall be due on or before thirty (30) days
after receipt of Seller's statement, to the payment address provided in Exhibit
B hereto. Overdue payments shall accrue interest at the Interest Rate from, and
including, the due date to, but excluding, the date of payment. If Buyer, in
good faith, disputes a statement, Buyer shall provide a written explanation
specifying in detail the basis for the dispute and pay the portion of such
statement conceded to be correct no later than the due date. If any amount
disputed by Buyer is


                                       15
MPC NON COLSTRIP 3
   16
determined to be due to Seller, it shall be paid within ten (10) days of such
determination, along with interest accrued at the Interest Rate from the
original due date until the date paid.

         10.2 SETOFF. If Buyer and Seller are each required to pay to the other
an amount in the same month under this Agreement, then such amounts with respect
to each Party may be aggregated and the Parties may discharge their obligations
to pay through netting, in which case the Party, if any, owing the greater
aggregate amount may pay to the other Party the difference between the amounts
owed. Each Party reserves to itself all rights, setoffs, counterclaims and other
remedies and defenses consistent with Article 12 (to the extent not expressly
herein waived or denied) which such Party has or may be entitled to arising from
or out of this Agreement. The obligations to make payment under this Agreement
between the Parties may be setoff against each other.

         10.3 AUDIT. Each Party (and its representatives) has the right, at its
sole expense and during normal working hours, to examine the records of the
other Party to the extent reasonably necessary to verify the accuracy of any
statement, charge or computation made pursuant to this Agreement. If requested,
a Party shall provide to the other Party statements evidencing the quantities of
energy delivered at the Delivery Point. If any such examination reveals any
inaccuracy in any statement, the necessary adjustments in such statement and the
payments thereof will be promptly made and shall bear interest calculated at the
Interest Rate from the date the overpayment or underpayment was made until paid;
provided, however, that no adjustment for any statement or payment will be made
unless objection to the accuracy thereof was made prior to the lapse of one (1)
year from the rendition thereof; and provided further that this Section 10.3
will survive any termination of this Agreement for a period of one (1) year from
the date of such termination for the purpose of such statement and payment
objections.

                           ASSIGNMENT; BINDING EFFECT

         11.1 ASSIGNMENT. Neither Party shall assign this Agreement or any of
its rights or obligations hereunder without the prior written consent of the
other Party, which consent shall not be unreasonably withheld or delayed.
Despite the foregoing, either Party may, without the need for consent from the
other Party (and without relieving itself from liability hereunder), (a)
transfer, sell, pledge, encumber or assign this Agreement or the accounts,
revenues or proceeds hereof in connection with any financing or other financial
arrangements; (b) transfer or assign this Agreement to an Affiliate of such
Party; or (c) transfer or assign this Agreement to any person or entity
succeeding to all or substantially all of the assets of such Party; provided,
however, that in the case of (b) and (c) any such assignee shall agree in
writing to be bound by the


                                       16

terms and conditions hereof. Assignments or transfers not in compliance with
this section shall be void.

         11.2 BINDINGS EFFECT. This Agreement shall inure to the benefit of and
be binding upon the Parties and their respective successors and permitted
assigns. No assignment or transfer permitted hereunder shall relieve Seller or
Buyer of any of their respective obligations under this Agreement.


                                   ARTICLE 12
                    FORCE MAJEURE AND LIMITATION OF LIABILITY

         12.1 FORCE MAJEURE. If either Party is rendered unable by Force Majeure
to carry out, in whole or part, its obligations under this Agreement and such
Party gives notice and full details of the event to the other Party as soon as
practicable after the occurrence of the event, then during the pendency of such
Force Majeure but for no longer period, the obligations of the Party affected by
the event (other than the obligation to make payments then due or becoming due
with respect to performance prior to the event) shall be excused to the extent
provided for herein. The Party affected by the Force Majeure shall remedy the
Force Majeure with all reasonable dispatch.

         12.2 LIMITATION OF REMEDIES, LIABILITY AND DAMAGES. THE PARTIES CONFIRM
THAT THE EXPRESS REMEDIES AND MEASURES OF DAMAGES PROVIDED IN THIS AGREEMENT
SATISFY THE ESSENTIAL PURPOSES HEREOF. FOR BREACH OF ANY PROVISION FOR WHICH AN
EXPRESS REMEDY OR MEASURE OF DAMAGES IS HEREIN PROVIDED, SUCH EXPRESS REMEDY OR
MEASURE OF DAMAGES SHALL BE THE SOLE AND EXCLUSIVE REMEDY, THE OBLIGOR'S
LIABILITY SHALL BE LIMITED AS SET FORTH IN SUCH PROVISION AND ALL OTHER REMEDIES
OR DAMAGES AT LAW OR IN EQUITY ARE WAIVED. IF NO REMEDY OR MEASURE OF DAMAGES IS
EXPRESSLY HEREIN PROVIDED, THE OBLIGOR'S LIABILITY SHALL BE LIMITED TO DIRECT
ACTUAL DAMAGES ONLY, SUCH DIRECT ACTUAL DAMAGES SHALL BE THE SOLE AND EXCLUSIVE
REMEDY AND ALL OTHER REMEDIES OR DAMAGES AT LAW OR IN EQUITY ARE WAIVED. UNLESS
EXPRESSLY PROVIDED IN THIS AGREEMENT, NEITHER PARTY SHALL BE LIABLE FOR
CONSEQUENTIAL, INCIDENTAL, SPECIAL, PUNITIVE, EXEMPLARY OR INDIRECT DAMAGES,
LOST PROFITS OR OTHER BUSINESS INTERRUPTION DAMAGES, BY STATUTE, IN TORT OR
CONTRACT, UNDER ANY INDEMNITY PROVISION OR OTHERWISE. IT IS THE INTENT OF THE
PARTIES THAT THE LIMITATIONS HEREIN IMPOSED ON REMEDIES AND THE MEASURE OF
DAMAGES BE WITHOUT REGARD TO THE CAUSE OR CAUSES RELATED THERETO, INCLUDING,
WITHOUT LIMITATION, THE NEGLIGENCE OF ANY PARTY, WHETHER SUCH NEGLIGENCE BE
SOLE, JOINT OR CONCURRENT, OR ACTIVE OR PASSIVE. TO THE EXTENT ANY DAMAGES
REQUIRED TO BE

PAID HEREUNDER ARE LIQUIDATED, THE PARTIES ACKNOWLEDGE THAT THE DAMAGES ARE
DIFFICULT OR IMPOSSIBLE TO DETERMINE, OTHERWISE OBTAINING AN ADEQUATE REMEDY IS
INCONVENIENT AND THE LIQUIDATED DAMAGES CONSTITUTE A REASONABLE APPROXIMATION OF
THE HARM OR LOSS.

         12.3 DUTY TO MITIGATE. Each Party agrees that it has a duty to mitigate
damages and covenants that it will use commercially reasonable efforts to
minimize any damages it may incur as a result of the other Party's performance
or non-performance of this Agreement.

         12.4 DISCLAIMER OF WARRANTIES. EXCEPT AS EXPRESSLY SET FORTH HEREIN,
SELLER EXPRESSLY NEGATES ANY OTHER REPRESENTATION OR WARRANTY, WRITTEN OR ORAL,
EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, ANY REPRESENTATION OR
WARRANTY WITH RESPECT TO CONFORMITY TO MODELS OR SAMPLES, MERCHANTABILITY, OR
FITNESS FOR ANY PARTICULAR PURPOSE.

Delivery Point. Buyer shall be responsible for all existing and any new sale,
use, excise, ad valorem, and any other similar taxes, imposed or levied by any
federal, state or local governmental agency on the energy sold and delivered
hereunder from and after the delivery of such energy to the Delivery Point. Each
Party shall indemnify, release, defend and hold harmless the other Party from
and against any and all liability for taxes imposed or assessed by any taxing
authority with respect to the energy sold, delivered and received hereunder that
are the responsibility of such Party pursuant to this Section 13.1.

         15.1 SECURITY. So long as a Party does not suffer a Material Adverse
Change, it is not obligated to furnish the other Party a guaranty of its
performance hereunder. If, however, a Party suffers a Material Adverse Change
and is unable to remedy such condition within thirty (30) days after the onset
of the condition, then, in addition to any other remedies it may have, the other
Party may require the Party suffering Material Adverse Change to provide
additional credit support, such as a letter of credit, corporate guarantee or
such other collateral mutually agreeable to both Parties.


                                   ARTICLE 16

article declared or rendered unlawful by a court of law or regulatory agency

                     WHOLESALE TRANSITION SERVICE AGREEMENT


                                  ENERGY CHARGE

         Seller will be paid a weighted monthly on-peak and off-peak Dow Jones
Mid Columbia index (as defined below, the "Index") price (computed as described
below) as long as the cumulative weighted average Index price does not exceed
22.25 mills per kWh. The cumulative weighted average Index price will become a
rolling twelve (12) month weighted average Index price starting in the
thirteenth (13th) month after the first month of the Delivery Term. If the
weighted monthly Index price is less than 20.00 mills per kWh, then the weighted
monthly Index price will be set at 20.00 mills per kWh. If the cumulative
weighted average Index price or the twelve (12) month weighted average Index
price exceeds 22.25 mills per kWh, then the monthly Index price will be set at
an amount that makes the cumulative weighted average Index price or the twelve
(12) month weighted average Index price index equal to 22.25 mills per kWh. The
weighted monthly Index price index will be computed as the Index price weighted
by the amount of energy actually delivered for each month by Seller. See the
examples included in this Exhibit for an illustration of the weighted monthly
Index price calculation (EXAMPLE 1 - CALCULATION OF MONTHLY WEIGHTED INDEX
PRICE) and an illustration of how the price paid will be computed using the
cumulative weighted average Index price and the twelve month rolling average
Index price (EXAMPLE 2 - PRICE PAID COMPUTATION).

         For purposes of this Agreement, "Index" means the prices in the Dow
Jones Mid-Columbia Electricity Firm Index reported by Dow Jones to Dow Jones
Telerate subscribers for on-peak hours and off-peak hours for each day of the
relevant billing month. If a price for any on-peak hour is not reported in the
Index, then the price for such unreported on-peak hour period shall be
determined by calculating the average of the Index prices last reported for the
on-peak hours period immediately preceding and immediately succeeding such
unreported on-peak hour period. If a price for any off-peak hour period is not
reported in the Index, then the price of such unreported off-peak hour period
shall be determined by calculating the average of the Index prices last reported
for the off-peak hours immediately preceding and immediately succeeding such
unreported off-peak hour period. "On-peak hours" are the hours between 6:00 a.m.
and 10:00 p.m. Pacific prevailing time, Monday through Saturday, exclusive of
holidays recognized by the North American Electric Reliability Council or its
successor. Off-peak hours are hours that are not on-peak hours provided however,
the total amount of energy actually sold by Seller and purchased by Buyer
hereunder shall not be included in the calculation of the on-peak and off-peak
Dow Jones Mid-Columbia Index reported by Dow Jones.
