                        TRANSACTIONS BETWEEN THE PARTIES

5.1 Transactions Between the Parties. Nothing in this Agreement shall prohibit
power purchase or sale Transactions between the Parties at arms-length terms and
conditions that fairly represent then-prevailing market terms. In any such
Transaction, EnergyPlus shall not act as PPLM's agent, and PPLM shall have the
sole discretion to enter into any such Transaction under which both EnergyPlus

                                   ARTICLE 6
                                 CONTRACT PRICE

6.1 Contract Price. PPLM shall pay EnergyPlus a fixed monthly fee for the
services performed by EnergyPlus under this Agreement based on the projections
set forth in Exhibit 3, subject to reconciliation as provided in Section 6.2.
Such fixed monthly fee shall only cover the fixed and operating costs incurred
at EnergyPlus' Allentown, Pennsylvania and Butte, Montana offices that are
directly associated with, or otherwise indirectly allocated on a
non-discriminatory basis to, the performance of EnergyPlus' obligations under
this Agreement. The projected fixed monthly fee is set forth in Exhibit 3 on a
monthly basis for the first twelve months and on an estimated annual basis
thereafter. EnergyPlus shall submit to PPLM by October 15 of each year during
the term of this Agreement a draft projected budget for the following year.

6.2 Reconciliation. Beginning twelve months after the Effective Date, the fixed
monthly fee paid by PPLM shall be reconciled on an annual basis with the actual
monthly fixed and operating costs incurred at EnergyPlus' Allentown,
Pennsylvania and Butte, Montana offices that are associated with the performance
of EnergyPlus' obligations under this Agreement. To the extent that the sum of
the actual monthly costs for a given year exceed the sum of the monthly fees
billed to PPLM for that year, PPLM shall pay EnergyPlus the difference between
the two amounts. To the extent that the sum of the actual monthly costs for a
given year is less than sum of the monthly fees paid by PPLM for that year,
EnergyPlus shall refund to PPLM the difference between the two amounts. At least
five (5) days prior to the end of each calendar quarter, EnergyPlus shall
provide to PPLM a variance analysis relative to the projection or annual budget
upon which the fixed monthly fee is annually determined.

days following the date by which either Party receives from the other Party
written notice of termination

take effect prior to the end of one (1) year following the Effective Date.

                                   ARTICLE 8
                                   ASSIGNMENT

8.1 Assignment. Neither Party shall assign this Agreement or its rights
hereunder; provided, however, that either Party may assign this Agreement to an
affiliate of PP&L Resources, Inc., but not sooner than twelve months after the
Effective Date. Provided, however, EnergyPlus shall not assign the Agreement to
any affiliate unless such affiliate has comparable expertise in power marketing
and a comparable financial condition.

                                   ARTICLE 9
                                    DEFAULT

9.1 Default. In the event either Party ("Defaulting Party") defaults in payment
or performance of any obligation to the other Party under this Agreement, such
default in payment or performance shall be deemed an Event of Default under this
Article if not cured within ten (10) Business Days following written notice by
the non-defaulting Party of such default in payment or performance. If an Event
of Default occurs, the non-defaulting Party, upon written notice given no later
than sixty (60) days after the discovery of the Event of Default, has the right
to (i) suspend performance under this Agreement; (ii) terminate this Agreement;
and/or (iii) withhold any payment due under this Agreement.
