GENERAL TERMS AND CONDITIONS

(Continued)

29.1(c)(i) continued

to serve the sum of all daily entitlements on the

portion of Transporter's system requiring curtailment

and the numerator of which is the quantity of Gas that

Transporter, in its sole judgment, reasonably believes

to be available to Transporter to serve all daily

entitlements within the area of Transporter's system

requiring curtailment. Transporter shall recompute the

Emergency Curtailment Entitlement Level as additional

information becomes available to Transporter.

(ii) If buyer experiences a shortage of supply to serve

emergency situations (including environmental

emergencies) or needs supply to forestall injury to life

or property and for minimum plant protection when the

plant is shut down, which requirements were expected to

be served with supplies purchased under Rate Schedule

S-1, sufficient supplies will be sold to Buyer to meet

such needs to the extent practicable but not exceeding

buyer's entitlement to quantities as provided for in the

Sales Agreement. Such quantity shall be considered

buyer's Emergency Curtailment Entitlement Level, if:

1. Buyer has certified that all users being currently

served with Gas purchased under Rate Schedule S-1

are actually using quantities for emergency

situations (including environmental emergencies) or

to forestall injury to life or property and for

minimum plant protection when the plant is shut

down; and

2. In order to serve buyer's needs, Transporter shall

not divert Gas from equal-priority users of other

buyers under similar circumstances and conditions.
