18.3 Creditworthiness (Continued)


(A) Creditworthiness for Firm Transportation Service (Continued)


(2) (Continued)


(b) Shipper will be deemed to be non-creditworthy if 1) it

is rated below a BBB/Baa2 equivalent standard by any

rating agency or if its credit limit is insufficient to

cover Shipper's total contractual obligation, as

described in Paragraph 18.3 (G) of these Transportation

General Terms and Conditions of Service, or 2) if

Shipper's credit limit as determined by GTN is

insufficient to cover Shipper's total contractual

obligation. GTN will inform Shipper in writing as to the

reasons Shipper has been deemed non-creditworthy.


If Shipper does not establish or maintain

creditworthiness as described above, Shipper has the

option of receiving transportation service under this

FERC Gas Tariff by providing to GTN a guarantee

acceptable to GTN, collateral (i.e., cash or letter of

credit), or security as described in (i) through (iv)

below. GTN may not unreasonably prevent a shipper from

later switching the type of credit alternative that it



(i) Guarantee: Shipper may obtain a guarantee of

financial performance in a form satisfactory to GTN

and for the term of the Gas Transportation

Agreement from a corporate affiliate of the Shipper

or a third party, either of which meets the

creditworthiness standard discussed above. For

these Shippers, the credit limit will be based upon

the financials of the guarantor. A form of

guarantee is available on GTN's Internet website.

If during the term of service the guarantor does

not meet the creditworthiness standards discussed

above, then GTN may request additional alternatives

as described in (i) through (iv) below.
