INTERRUPTIBLE TRANSPORTATION SERVICE

(Continued)

3. PRIORITY OF SERVICE AND ALLOCATION OF CAPACITY (Continued)

(ii) Any capacity remaining after step (i) shall be

allocated to any other person which has executed an

Interruptible Transportation Service Agreement. In

accordance with Section l.2 herein, allocation of

capacity within this category shall be provided to

Shippers willing and able to pay the maximum rate on a

first-come, first-served basis, determined as of the time

and date Transporter received each Shipper's valid

request as described in Section 12 of the Transportation

General Terms and Conditions; provided, however, that at

the beginning of each month priority will be given to any

Shipper that continues to transport up to the average

daily quantities of gas within MDTQ to the same Delivery

Point(s) as were scheduled and confirmed in the

immediately preceding month if Shipper agrees to pay the

maximum rate. Average daily quantities of gas shall be

determined by taking the total quantity of gas scheduled

and confirmed at the Delivery Point(s) in the preceding

month divided by the total number of days in such month.

All such requests received within seven (7) days after

the date that Transporter stipulates in its public notice

that it is accepting requests for transportation service

shall, if such requests are valid in compliance with

Section 12 of the General Terms and Conditions, be deemed

to have been received concurrently and shall have the

same request date. Transporter shall issue such notice a

minimum of ten (10) days prior to the date that

Transporter commences accepting requests for

interruptible transportation service hereunder. If

curtailment is necessary within this category, such

curtailment shall commence with the Shipper which has the

most recent valid request who shall be fully curtailed

before any other Shipper, then the Shipper with the next

most recent valid request, and so on.
