28.6 Bidding for a Parcel

(a) Preliminary Qualification

Replacement Shippers are encouraged to pre-qualify in

advance of any postings on GTN's EBB as credit

requirements will take differing amounts of time to

process depending on the particular financial profile

of Replacement Shippers. The pre-qualification process

will authorize a pre-set maximum monthly financial

exposure level for the Replacement Shipper. Such

exposure levels may be adjusted by GTN

periodically re-evaluating a Replacement Shipper's

credit-worthiness.

Releasing Shippers may exercise their option to waive

the credit requirements for any Replacement Shipper

wishing to bid on a Parcel posted by that Releasing

Shipper. Such waiver must be made on a nondiscriminatory

basis. GTN must be informed of such waiver via

the EBB before it will authorize such Replacement

Shipper's participation with respect to that particular

Parcel. In this instance, no pre-set maximum monthly

financial exposure level is applicable.

Should a Releasing Shipper waive the credit requirements

for a Replacement Shipper, the Releasing Shipper shall

be liable for all charges incurred by the Replacement

Shipper in the event such Replacement Shipper defaults

on payment to GTN for such capacity release

service.
