of GMP the GMP share of TTC for Phase I/II
based on a 9.26191% share of Phase I/II (combined percentage interest
per Restated Use Agreement effective 9/1/2001). The GMP TTC share is 185 MW
based on a maximum TTC of 2000 for Phase I/II. The Phase I/II share includes
interconnection rights of others per a brokering agreement with GMP. Effective April 1, 2003 GMP began brokering
for Fitchburg Gas and Electric Light Company and Unitil

Phase I/II Interconnection rights of Interconnection Rights Holders that are
parties to the Agreement. The Aggregate
Brokered Transmission Capacity is the sum of the available Phase I/II capacity
of GMP and the two Other IRH that are parties to the
Agreement.

sales. As a result of this and the above
and based on a TTC of 2000, GMP offers 26 MW non-firm service over Phase I/II
beyond the operating horizon with a maximum term of one month. For hourly and daily service in the operating
horizon, GMP will offer all transmission released as non-firm as outlined
above. The amount of service release
will vary from day to day, but GMP will offer at least 26 MW of non-firm
service at all times and up to 185 MW of non-firm service for some hours
depending on how much Firm service is released based on a TTC of 2000.
For northbound service, the
maximum TTC for Phase I/II transmission from NEPOOL to Quebec is 1200 MW,
resulting in ATC of 114 MW based on the combined percentage interest of the
Aggregate Brokered Transmission Capacity and assigned rights of 9.57385%.
