TRANSPORTATION GENERAL TERMS AND CONDITIONS

(Continued)

18. OPERATING PROVISIONS (Continued)

18.3 Creditworthiness

(A) Creditworthiness for Firm Transportation Service

(1) GTN shall not be required to perform or to continue

transportation service under this FERC Gas Tariff, Third

Revised Volume 1-A, on behalf of any Shipper who, after

GTN's request, fails to establish or confirm

creditworthiness. If Shipper is found by GTN to be non-

creditworthy, GTN will, upon request, inform Shipper in

writing as to the reasons Shipper has been deemed non-

creditworthy.

If Shipper's credit standing ceases to meet GTN's credit

requirements during the period of service, then GTN has

the right to require security as specified herein. Upon

notification by GTN that Shipper no longer meets GTN's

creditworthiness standards, Shipper must, within five (5)

business days, pay for one month of service in advance to

continue service. Shipper must, within thirty (30) days,

provide an acceptable guarantee or either a three-month

cash security deposit or letter of credit, consistent with

GTN's creditworthiness standards for Existing Capacity

shippers. For shippers utilizing Expansion Capacity on

lateral facilities, the security that must be provided

within thirty (30) days will not be greater than a

shipper's pro rata share of the total facilities costs,

and such security will be reduced over time in proportion

to the shipper's contract term. If Shipper fails to

provide one of the credit alternatives within these time

periods, GTN may suspend service immediately (Shippers are

not responsible for reservation charges after service is

suspended) and may provide simultaneous written notice to

Shipper, the Commission, and any replacement Shipper(s)

that service will be terminated in thirty (30) days. GTN

also may exercise any other remedy available to it

hereunder, at law or in equity.
