The provisions of this Section 25 are applicable only to services under

Rate Schedules SS-1 or SS-2. This Section 25 is intended to preserve, to

the extent possible, all the terms of service formerly provided by Penn-

York Energy Corporation ("Penn-York") before Penn-York was merged into

Transporter in 1994. This Section 25 contains the General Terms and

Conditions from Penn-York's tariff upon the effective date of that

merger, except for any Penn-York tariff provision which was effectively

the same as another provision in Transporter's General Terms and

Conditions. Transporter's other General Terms and Conditions shall

govern services under Rate Schedules SS-1 or SS-2 except to the extent of

any conflict with the provisions of this Section 25, in which case the

provisions of this Section 25 shall govern.
