NOW, THEREFORE, in consideration of the mutual promises and agreements set forth herein, the Parties hereto agree as follows:

ARTICLE I

TRANSITION SERVICES

1.1 Transition Services; TSA Releases.

(a) The Transition Services to be provided hereunder shall be set forth in more detail in individual TSA Releases (each, a “TSA Release”), which shall set forth the Transition Services to be provided pursuant thereto in a manner and level of detail reasonably satisfactory to both the Provider and the Recipient thereunder. The TSA Releases shall be numbered sequentially and shall be in substantially the form of Exhibit A attached hereto.

(b) Each TSA Release shall specify if the Provider and/or Recipient thereunder is to be one or more designated affiliates of the Parties. In such event, references herein to “Provider” and “Recipient” shall mean such designated affiliate(s), provided that it is understood and agreed that such designated affiliates shall not thereby become parties to this Agreement or the TSA Release and each Party shall be responsible to the other Party and its respective affiliates (but not to any third parties) for the acts or omissions of their respective designated affiliates as Provider or Recipient, as applicable, pursuant to this Agreement.

(c) Where PPL or its designated affiliate is the Provider hereunder, the Provider shall perform, or cause to be performed, the Transition Services in a manner (including quality) substantially consistent with, and in no event more extensive in type and scope than, the provision of similar or comparable services provided by the Parent Group to the Energy Supply Group prior to the date of the Transaction Agreement (it being understood that the provision by the Parent Group of Transition Services to any member of the Combined Group that was not a Subsidiary of Parent prior to the date of the Transaction Agreement, and services performed in connection with the consummation of the Transactions, shall not be deemed to be more extensive in type or scope than the provision of similar or comparable services by the Parent Group to the Energy Supply Group prior to the date of the Transaction Agreement). Where Energy Supply or its designated affiliate is the Provider hereunder, the Provider shall perform, or cause to be performed, the Transition Services in a manner (including quality) substantially consistent with, and in no event more extensive in type and scope than, the provision of similar or comparable services provided by Energy Supply Employees (as defined in the Employee Matters Agreement) to the Parent Group prior to the date of the Transaction Agreement (it being understood that services performed in connection with the consummation of the Transactions shall not be deemed to be more extensive than the provision of similar or comparable services by such employees to the Parent Group prior to the date of the Transaction Agreement).

(d) During the Term (as defined below), the Provider shall consider in good faith any reasonable requests of Recipient for the provision of additional transition services not provided for under existing TSA Releases. To the extent the Parties reach agreement on the provision of such additional services or any other revisions to an existing TSA Release, the Parties shall enter into a new or revised TSA Release, which shall be effective when signed by an Authorized Representative and the TSA Coordinator (as defined below) of each Party.

(e) If requested by the Recipient, the Provider shall include in the TSA Release a good faith estimate of the Provider Cost (as defined in Section 2.1 below) associated with the applicable Transition Services (to the extent such costs are reasonably estimable); provided, however that the provision of such estimate shall not be deemed to cap the Provider’s right to payment for such Transition Services at the estimate amount.

(f) Each TSA Release shall provide the name and contact details of one or more persons who are authorized to coordinate the provision of the applicable Transition Services for each Party (each such person with respect to the applicable TSA Release, the “TSA Coordinator”). The TSA Coordinator shall have no authority to amend or waive any provision of this Agreement or, except as specifically set forth therein, the TSA Release.

(g) In the event of any inconsistency between a TSA Release and the terms of this Agreement, the terms of this Agreement shall control unless expressly agreed in a separate writing signed by an Authorized Representative of the Party against whom enforcement is sought.

(h) For purposes of this Agreement, Authorized Representative shall mean (i) any authorized executive officer of PPL and Energy Supply, respectively; and (ii) with respect to TSA Releases or other matters, those individuals as designated in a notice pursuant to Section 5.1 hereof.

- 2 -

1.2 Period Transition Services Will Be Provided. Transition Services shall be provided beginning as of the Closing Date and shall continue through the expiration of the term relating to each Transition Service as set forth in the applicable TSA Release, unless (a) the Recipient terminates a particular Transition Service in accordance with the terms and conditions of this Agreement, (b) otherwise mutually agreed by the Parties in writing, or (c) this Agreement is terminated pursuant to its terms at an earlier date. If no expiration date is stated, the Transition Service will continue for the Term (as defined below).

1.3 Term. The term of this Agreement (the “Term”) shall commence as of the Closing Date and shall continue until the date that is twenty four (24) months from the Closing Date (the “Expiration Date”), subject to earlier termination pursuant to Article IV or written agreement otherwise by the Parties.

1.4 Commingling of Assets. To the extent a Provider shall have charge or possession of any of the Recipient’s cash or cash equivalents in connection with the provision of the Transition Services, such Provider shall (i) hold such cash or cash equivalents in the name and for the benefit of the Recipient and (ii) separately maintain, and not commingle, such cash or cash equivalents with any cash or cash equivalents of the Provider, its affiliates or any other person.

ARTICLE II

COMPENSATION FOR TRANSITION SERVICES

2.1 Fees. As consideration for the Transition Services received, the Recipient shall pay to the Provider for each Transition Service an amount equal to the cost of providing such Transition Services, in each case, in accordance with PPL’s cost allocation methodology in effect on the date of the Transaction Agreement (without subsidization of the Recipient’s business operations or margin to the Provider) as further set forth on Exhibit B attached hereto (the “Provider Cost”); provided that (i) to the extent the Transition Services are provided by a franchised public utility that has captive customers or that owns or provides transmission service the price of such Transition Services shall be the higher of Provider Cost or market as described in 35 C.F.R. § 35.44 (b)(2), and (ii) to the extent the Transition Services are provided to a franchised public utility that has captive customers or that owns or provides transmission service the price of such Transition Services shall be the lower of Provider Cost or market as described in 35 C.F.R. § 35.44(b)(2). The Parties shall specify in the applicable TSA Release whether Transition Services are expected to be provided by or to a franchised public utility Affiliate, and shall use commercially reasonable efforts to cause the Transition Services to be provided by or to Affiliates that are not franchised public utilities.

2.2 Payment Terms. The Provider shall present the Recipient (on account of Transition Services provided to such other Party as Recipient) with monthly invoices for the Transition Services it provides. The format of such invoices shall include, without limitation, a brief description of the applicable Transition Service, the billing period, applicable fees, and such other information as the applicable Recipient(s) may reasonably request to verify the amount and allocation of costs for the Transition Services. The Recipient shall pay the undisputed amount of the monthly invoiced amount within thirty (30) days after the date such monthly invoice was

- 3 -

received. If the Recipient in good faith disputes any portion of the amount due on any invoice, the Recipient shall notify the Provider in writing of the nature and basis of the dispute as soon as commercially reasonable, but no later than one hundred eighty (180) days from the date of such invoice.

2.3 Audit Rights. During the Term, and for a period of six (6) months thereafter, the Recipient shall have the right, at its own costs and expense, to conduct or cause to be conducted, a reasonable audit of the data, books and records and other pertinent information of the Provider concerning the provision of Transition Services hereunder, including without limitation, for purposes of disputing the calculation of any fees charged under this Agreement or for preparing financial statements. Without limiting the generality of the foregoing, in connection with the exercise of the Recipient’s audit right, the Provider shall also provide the Recipient with reasonable access to the Provider’s pertinent personnel and third-party financial, accounting and tax advisors and allow Recipient to perform testing procedures, including inspection, observation and inquiries related to the design and operations of the controls related to the processes performed by the Provider; provided that the Recipient (including its personnel) and its third-party advisors shall not be required to provide information to the Recipient that (x) could reasonably be expected to result in competitive harm to the Provider as a result of such disclosure or (y) would waive any legal privilege. The Recipient shall provide at least ten (10) Business Day’s advance notice of any such audit, and shall conduct such audit during normal business hours and in such a manner so as to reasonably minimize disruptions to the Provider and its Affiliates. If the Provider objects to the scope of any such audit requested, the Parties shall work together, in good faith, to mutually reach agreement on the proper scope of such audit.

2.4 Dispute Resolution. If the Recipient raises a dispute with respect any charges under this Agreement within the period set forth in Section 2.2, then the Parties shall negotiate in good faith and attempt to resolve the dispute. Should such negotiations fail to result in an agreement within sixty (60) days after receipt by the Provider of such written dispute from the Recipient, then the matter shall be submitted to a mutually agreeable independent arbitrator which may, but does not necessarily have to be, the Independent Accountant. The arbitrator will deliver to the Parties a written determination (along with a statement of reasons therefor) of the amounts payable under this Agreement with respect to any such dispute within 30 days (or such other time period as may be agreed) following the submission of the dispute to the arbitrator, which determination shall be final, binding non-appealable and conclusive on the Parties. The determination of the arbitrator shall be based solely on presentations and written materials submitted by the Provider and the Recipient and the terms of this Agreement and not on the basis of an independent review. The Recipient and the Provider will, and will cause their respective representatives to, cooperate and assist the arbitrator as reasonably requested by the arbitrator in the conduct of the review and resolution referred to in this Section 2.4, including the making available, to the extent necessary, books, records, work papers, and personnel relevant to the dispute. Each Party to the dispute shall pay its own costs and expenses incurred under this Section 2.4. All fees and expenses relating to the work, if any, to be performed by the arbitrator pursuant to this Section 2.4 will be allocated between the Parties to the dispute in inverse proportion as each shall prevail in respect of the dollar amount of disputed items so submitted (as finally determined by the arbitrator). Any disputed amount determined by the Provider and Recipient, or if submitted to the arbitrator and determined by the arbitrator, to be payable to the Provider, together with interest thereon at the rate of ten percent (10%) per annum from the thirtieth (30th) day after the

- 4 -

applicable invoice was received by the Recipient through the date of payment, shall be due and payable to the Provider by wire transfer of immediately available funds to such account or accounts as shall be specified by the Provider within three (3) Business Days after such amounts are finally determined as provided in this Section 2.4.

2.5 Cooperation, Information and Access; Monthly Meeting.

(a) The Parties will cooperate in good faith in all matters relating to the provision and receipt of the Transition Services. Without limiting the generality of the foregoing, the Recipient will provide (or cause to be provided) to the applicable Provider in a timely manner, access to facilities and information required or reasonably requested by the Provider in connection with providing the Transition Services; provided, however, the Recipient shall not be required to provide access to information that (x) could reasonably be expected to result in competitive harm to the Provider as a result of such disclosure, (y) would be in violation of applicable Law or (z) would waive any legal privilege.

(b) The TSA Coordinators shall conduct a joint monthly meeting at a mutually agreed time to discuss, inter alia, cost/quality of Transition Services, scope changes, and coordination of activities including spin-down, current and future projects; provided, however, each such meeting may be canceled in advance upon the mutual agreement of the applicable TSA Coordinators.

2.6 Additional Resources. Except as may be required to comply with its mitigation obligations under Section 4.2, in providing the Transition Services, the Provider is not obligated to (i) hire any additional employees, (ii) maintain the employment of any specific employee, (iii) purchase, lease, or license any additional equipment or materials, or (iv) enter into new contracts or extend current contracts, except as otherwise provided in the Separation Agreement, the Transaction Agreement or the Employee Matters Agreement. The Provider may engage one or more subcontractors to provide all or any portion of the Transition Services, provided that PPL or Energy Supply, as applicable, remains directly responsible to the other (but not to third parties) for the obligations of it or its designated affiliate as Provider hereunder.

2.7 Third Party Consents.

(a) To the extent that the provision of any Transition Services to any Recipient under this Agreement requires any new or additional third party consents, licenses, rights, approvals or permissions by or on behalf of the Provider (the “Third Party Consents”) for the Recipient to receive and enjoy the full benefit of the Transition Services, and to use any deliverables provided in connection therewith, the obligation to provide such Transition Services are contingent upon receipt by the Provider of such Third Party Consents, it being acknowledged and understood that those third parties are not bound to this Agreement. Each TSA Release will set forth a list of all identified material Third Party Consents required for performance of the Transition Services.

(b) Any fees or other reasonable out-of-pocket costs to obtain any Third Party Consents (the “TSA Consent Fees”) necessary to separate assets, including but not limited to licenses and data, shall be paid (or reimbursed) by the Provider. Any TSA Consent Fees necessary for the Provider to provide Transition Services to the Recipient shall, except as otherwise provided in the Separation Agreement, the Transaction Agreement or the Employee Matters Agreement,

- 5 -

be paid (or reimbursed) by the Recipient as part of the applicable fees; provided that, (i) the Provider shall use reasonable efforts to provide the Recipient with at least ten (10) Business Days written notice before the payment of any proposed TSA Consent Fees; (ii) the Provider shall use reasonable efforts to fulfill its obligations under this Agreement in a cost-efficient manner and without the incurrence of TSA Consent Fees; and (iii) the Recipient may decline all or part of any applicable Transition Services as necessary to avoid such TSA Consent Fees. Without limitation of any of its obligations under the Separation Agreement, the Transaction Agreement or the Employee Matters Agreement, the Provider shall use commercially reasonable efforts to obtain such Third Party Consents as promptly as practicable, and the Recipient shall reasonably assist the Provider in such efforts. The Provider shall provide the Recipient with copies of the vendor invoices for such Third Party Consents in reasonably sufficient detail to verify the terms of such Third Party Consents. No Provider shall have any obligation to commence performance of any Transition Service until the requisite Third Party Consent has been obtained. If the Provider fails to obtain the requisite Third Party Consent for any Transition Service after commencement of such service, the Provider shall use commercially reasonable efforts to give the Recipient at least thirty (30) days’ notice before discontinuing the Transition Service for which the requisite Third Party Consent was not obtained, and, for purposes of Section 5.12(a) of the Transaction Agreement, such discontinued Transition Service shall thereafter not be considered a service provided pursuant to this Agreement.

2.8 Energy Supply Assets and Separation Costs. To the extent that any of the Transition Services provided to Energy Supply or its designated affiliates (as Recipient) by or on behalf of PPL or its designated affiliate (as Provider) include any Energy Supply Assets, Spin Transactions, Separation Costs and/or Shared Contracts (or other items the cost of which are to be borne by PPL or Parent pursuant to the Separation Agreement, the Transaction Agreement and/or the Employee Matters Agreement), Energy Supply or its designated affiliates (as Recipient) may, in accordance with and subject to Section 2.2, dispute the amount on any invoice related to such Transition Services to reduce or adjust the net amounts paid or payable by such Recipient to such Provider for such Transition Services so that PPL bears the costs of such Energy Supply Assets, Spin Transactions, Separation Costs, Shared Contracts and/or other items, in each case in accordance with, and solely to the extent provided for in, the Separation Agreement, the Transaction Agreement and/or the Employee Matters Agreement.
