1 Exhibit 10.14 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." RECITALS 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.

(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. ARTICLE 10 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. ARTICLE 11 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.

PP&L MONTANA, LLC By: /s/ Roger Petersen -------------------------------------------- Name: Roger Petersen -------------------------------------------- Title: President ------------------------------------------- THE MONTANA POWER COMPANY By: /s/ Michael E. Zimmerman -------------------------------------------- Name: Michael E. Zimmerman -------------------------------------------- Title: Vice President & General Counsel ------------------------------------------- MPC NON COLSTRIP 3 21 22 EXHIBIT A TO THE 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.
