                                    CONTRACT

          period, the Party affected by the event (other than the obligation to
          make payments then due or becoming due with respect to performance
          which occurred prior to the event) shall be relieved of its
          obligations insofar as they are affected by Force Majeure but for no
          longer period. The Party affected by an event of Force Majeure shall
          provide the other Party with written notice setting forth the full
          details thereof as soon as practicable after the occurrence of such
          event and shall take all reasonable measures to mitigate or minimize
          the effects of such event of Force Majeure; provided, however, that
          this provision shall not require PPL to deliver, or Customer to
          receive, Electricity at points other than the Delivery Point, or
          require either Party to settle labor disputes.

     b)   Definition. Force Majeure means an event not anticipated as of the
          Commencement Date, which is not within the reasonable control of the
          Party (or in the case of third party obligations or facilities, the
          third party) claiming suspension (the "Claiming Party"), and which, by
          the exercise of due diligence, the Claiming Party, or third party, is
          unable to overcome or avoid or cause to be avoided. Events of Force
          Majeure may include, but are not restricted to: acts of God; fire;
          civil disturbance; labor dispute; labor or material shortage;
          sabotage; action or restraint by court order or public or governmental
          authority (so long as the Claiming Party has not applied for or
          assisted in the application for such government action); provided,
          however, that an event of Force Majeure shall not include (i)
          Customer's inability economically to use Electricity hereunder; (ii)
          Customer's ability to procure more economic electric supply; or (iii)
          PPL's ability to sell Electricity at a more advantageous price.

12.  CONDITIONS PRECEDENT/CREDIT REQUIREMENTS - This Agreement shall not be
     deemed to be valid and binding upon the Parties until the occurrence of
     each of the following conditions precedent: (i) credit approval of Customer
     by PPL, and (ii) if applicable, Customer being selected to participate in
     the retail access program of the Customer's EDC, and (iii) PPL becoming
     authorized to supply electricity to Customer under the retail access
     program of Customer's EDC. PPL shall have no liability for any delay in
     electricity service which is due to the actions or inactions of Customer's
     EDC, or which is the direct or indirect result of Customer failing to
     provide PPL with true and accurate information.

     Customer hereby authorizes PPL to obtain credit information regarding
     Customer from the EDC that currently provides service to Customer and its
     Facilities. Customer also authorizes PPL to make such inquiries as PPL
     considers to be necessary to obtain credit information and authorizes
     Customer's bank, at any time and from time to time while this Agreement is
     in effect, to release credit information regarding Customer. In the event
     PPL makes a good faith and commercially reasonable determination that
     Customer has encountered a "material adverse change" in its financial
     condition, PPL reserves the right (i) to request a modification of the
     terms of this Agreement, including the terms of any Purchasing Attachment,
     upon written notice to Customer to account for such material adverse
     change, which modifications may include without limitation increasing the
     price(s) for electricity hereunder, requiring Customer to provide a letter
     of credit, cash deposit, surety bond, or third party guaranty (provided in
     a format and by a financial institution, insurer, or guarantor acceptable
     to PPL), or (ii) to terminate this Agreement upon the provision of ten (10)
     days written notice. As used in this Section 12, a "material adverse
     change" shall mean (a) a downgrade of the Customer's long-term senior,
     unsecured debt (not supported by third party credit enhancement) below B by
     Standard & Poors or B2 by Moody's, or (b) Customer's failure to maintain
     any form of performance assurance, such as cash, Letters of Credit or
     surety bonds, that may be required by PPL hereunder or under any Purchasing
     Attachment.

                         TRANSMISSION AGENCY AGREEMENT
                                   ATTACHMENT

         THIS TRANSMISSION AGENCY AGREEMENT ATTACHMENT (this "Agency
Relationship") is attached to and is a part of the Retail Electricity Supply
Contract for Firm Electricity Supply ("Retail Contract"), dated as of December
11, 2001, between PPL EnergyPlus, LLC ("PPL") and the Customer specified on the
Retail Electricity Supply Contract ("Customer"). PPL and Customer may sometimes
be referred to herein individually as "Party" and collectively as the "Parties".

1.   TRANSMISSION SERVICE. Pursuant to the terms in Section 5 of the Retail
     Electricity Supply Contract, Customer is required to arrange and pay for
     transmission and delivery of such electricity supply from the Delivery
     Point(s), as defined in the Purchasing Attachment. Further, the Customer
     has entered into a transmission agreement with an Electric Transmission
     Provider ("ETP") in which the ETP will transmit, pursuant to the ETP's Open
     Access Transmission Tariff ("OATT"), the electricity supply to be delivered
     by PPL from the Delivery Point(s) to the Facility(ies), as identified in
     the Purchasing Attachment.

2.   DESIGNATION OF AGENCY. Customer hereby appoints PPL to act as its
     Designated Agent, as defined in the Customer's ETP's OATT, and on its
     behalf with respect to arranging and scheduling transmission and ancillary
     services on the ETP's transmission system for the electricity supply
     purchased by Customer from PPL. Services to be performed by PPL at
     Customer's direction and on its behalf shall include without limitation:

     a)   acting as Customer's primary contact with Customer's ETP regarding
          issues relating to or affecting Customer's transmission and ancillary
          services from the ETP; and

     b)   reserving and scheduling Transmission Service with Customer's ETP, as
          identified and defined in the ETP's OATT, including losses and
          ancillary services, pursuant to and in accordance with the terms and
          conditions of the ETP's OATT and the Retail Contract.

     Nothing herein, however, shall prohibit Customer from obtaining ancillary
     services independent of PPL.

3.   CUSTOMER ARRANGEMENTS. Customer recognizes and agrees that pursuant to
     Section 5 of the Retail Electricity Supply Contract, Customer is
     responsible for obtaining, reviewing, negotiating and executing all
     agreements, documents or other instruments required by or pursuant to the
     ETP's OATT necessary for Customer to be deemed an "Eligible Customer" under
     and to receive services pursuant to the ETP's OATT. PPL shall have no
     obligation hereunder to assist or advise Customer with respect to such
     agreements and documents. Customer shall take all actions necessary to have
     PPL recognized as Customer's "Designated Agent" pursuant to the OATT.

4.   PAYMENT. Customer shall be responsible for payment to the ETP for all
     services provided to Customer by its ETP under the ETP's OATT, as well as
     all payments for ancillary services, irrespective of how and from whom such
     ancillary services are procured. Customer shall insure that all original
     invoices for such services are sent by the ETP and any ancillary services
     provider to Customer for payment. PPL shall not be liable to Customer's ETP
     or any third party provider for any payment for any such services provided
     to Customer.

5.   SCHEDULING.

     (a)  If applicable, Customer shall notify PPL of its Scheduled Quantity
          (Committed Quantity plus Additional Quantity less Surplus Power)
          including transmission and distribution losses, in whole megawatt
          increment(s), no later than 6:30 a.m. (Mountain Prevailing Time) of
          the first business day prior to the start of the date when the
          Scheduled Quantity is to be delivered to Customer. However, a request
          by the Customer for Scheduled Quantities to be delivered on any
          Saturday, Sunday or Monday shall be submitted to PPL no later than
          6:30 a.m. (MPT) on Thursday for Saturday delivery and 6:30 a.m. (MPT)
          Friday for Sunday and Monday delivery. For Holidays, Customer shall
          provide notice no later than 6:30 a.m. (MPT) on the Western Systems
          Coordinating Council (WSCC), or its successor(s), designated
          pre-scheduling day for that Holiday. These deadlines may be revised
          for changes in the WSCC, or its successor(s) scheduling practices by
          written notification to Customer. At a minimum, Customer shall specify
          the MW quantity and the start and end times of the delivery of the
          Scheduled Quantity. Unless otherwise provided in a Purchasing
          Attachment hereto, if Customer fails to notify PPL within the time
          frame indicated in this paragraph, PPL is under no obligation to
          provide the Scheduled Quantity requested. Customer shall notify PPL in
          accordance with the Notification Procedures detailed in Section 6
          below. Customer and PPL shall cooperate to ensure that schedules and
          Scheduled Quantities are timely and reflect the actual expected
          deliveries of electricity supply to the Customer's Facilities,
          provided however, that notwithstanding such cooperation, Customer
          shall be liable for all energy

                         TRANSMISSION AGENCY AGREEMENT
                                   ATTACHMENT

          imbalance charges and other related charges incurred as a result of
          Customer's Scheduled Quantities, except to the extent caused solely by
          PPL's negligence or willful misconduct.

     (b)  Customer shall be responsible for providing PPL with the Scheduled
          Quantity. Except to the extent caused solely by PPL's negligence or
          willful misconduct, PPL shall not be liable to Customer for any
          damages that may result, including the failure to schedule or reserve
          sufficient transmission, if such failure was related, in whole or in
          part, directly or indirectly, to inaccuracies in or the Customer's
          failure to supply PPL with the Scheduled Quantity as required by
          Section 5(a).

6.   NOTIFICATION PROCEDURES: Each Party shall notify the other if the
     Customer's ETP provides notice of a distribution or transmission outage
     that will impact the Customer's Facility(ies). In the event of a planned
     outage, the notifying Party shall provide notification the sooner of at
     least one full business day in advance or no later than 6:30 am Mountain
     Prevailing Time (MPT) of the preceding business day. In the event of any
     unplanned outage, the notifying Party shall provide the other Party with
     all the information received from the ETP or EDC, but at a minimum, the
     amount of load/supply reduction, start time and end time.

7.   REVOCATION. Notwithstanding any contrary provision, Customer and PPL shall
     each have the right to revoke and terminate, upon thirty (30) day's prior
     written notice, the agency relationship set forth herein. However, such
     revocation shall not relieve either Party from any responsibilities
     described in the Retail Electricity Supply Contract or other Attachments to
     the Agreement. Upon such revocation, Customer shall notify the ETP that PPL
     is no longer acting as Customer's Designated Agent.

8.   MISCELLANEOUS.

     (a)  ASSIGNMENT. This Agency Relationship is not assignable by either Party
          without the prior written consent of the non-assigning Party, which
          consent shall not be unreasonably withheld, delayed or conditioned.
          Any assignment without the prior approval of the non-assigning Party
          is voidable by such non-assigning Party.

     (b)  AMENDMENT/BINDING EFFECT. This Agency Relationship may not be amended,
          changed, modified, or altered unless such amendment, change,
          modification, or alteration is in writing and signed by both Parties
          to the Agreement or their successor in interest. This Agency
          Relationship inures to the benefit of and is binding upon the Parties
          and their respective successors and permitted assigns.

     (c)  SEVERABILITY. If any article, section, phrase or portion of this
          Agency Relationship is, for any reason, held or adjudged to be
          invalid, illegal or unenforceable by any court of competent
          jurisdiction, such article, section, phrase, or portion so adjudged
          will be deemed separate, severable and independent and the remainder
          of this Agency Relationship will be and remain in full force and
          effect and will not be invalidated or rendered illegal or
          unenforceable or otherwise affected by such adjudication, provided the
          basic purpose of this Agency Relationship and the benefits to the
          Parties are not substantially impaired.

     (d)  ENTIRE AGENCY RELATIONSHIP. This Agency Relationship completely and
          fully supersedes all other understandings or agreements, both written
          and oral, including any term sheet or confirmation, between the
          Parties relating to the subject matter hereof.

     (e)  WAIVER. No delay or omission by a Party in the exercise of any right
          under this Agency Relationship shall be taken, construed, or
          considered as a waiver or relinquishment thereof, and any such right
          may be exercised from time to time and as often as may be deemed
          expedient. If any of the terms and conditions herein are breached and
          thereafter waived by a Party, such waiver is limited to the particular
          breach so waived and is not deemed to waive any other breach
          hereunder.

         IN WITNESS WHEREOF, the Parties have caused this Agency Relationship to
be signed by their respective duly authorized representative as of the date
first set forth on the Retail Electricity Supply Contract.
