GENERAL TERMS AND CONDITIONS (Continued)

14. SUPPLY CURTAILMENT (Continued)

14.3.3 If the quantity of Merchant Division's gas available

for a priority category is inadequate to meet the

Priority Relief Requirements of those Shippers entitled

to relief in such priority category, the quantity of

Merchant Division's gas to be assigned to each Shipper

in such category shall be its prorated share based on

the ratio of the Shipper's Priority Relief Requirements

in that category to the total Priority Relief

Requirements of all Shippers in such category. In no

event, however, shall the protection afforded by the

provisions hereof result in volumes delivered to

Shipper in excess of its Daily Sales Entitlement.

14.4 Relief from Curtailment in Emergency Situations: Transporter

recognizes that exceptions to the levels of curtailment

resulting from this Section 14 may be required in response to

emergency situations (including environmental emergencies) when

deliveries of gas in excess of curtailed levels are required to

forestall irreparable injury to life or property or to provide

for minimum plant protection. Any Shipper seeking emergency

relief on this basis shall have the burden of establishing the

nature and extent of its problem and the minimum quantity of

gas needed to avoid irreparable injury to life or property.

Transporter shall not be liable for granting exceptions from

curtailment if such exception is based upon information

submitted by Shipper to Transporter. In no event, however,

shall the protection afforded by the provisions hereof result

in volumes delivered to Shipper in excess of its Daily Sales

Entitlement.

When Shipper declares an emergency situation in order to

forestall irreparable injury to life or property, Shipper shall

certify to Transporter by affidavit:

(1) the nature and extent of the emergency;

(2) that all sources of gas supply available to Shipper,

including peak-shaving and storage, have been utilized

to the fullest extent possible;

(3) that all interruptible services of Shipper have been

curtailed during such emergency situation;
