GENERAL TERMS AND CONDITIONS (Continued)

17. FIRM CAPACITY RELEASE MECHANISM (Continued)

17.3.3 All offers of or bids on capacity release shall be

submitted to Transporter by Releasing Shipper or potential

Replacement Shipper, via an acceptable electronic communication

mechanism, as described in Section 8 of these General Terms and

Conditions.

17.3.3.1 Transporter will accept offers of or bids on

capacity release received via an alternate method, i.e.

facsimile, mail or hand-delivery, in an emergency situation,

such as the failure of Transporter's acceptable electronic

communication mechanism utilized by Shipper or, at the

discretion of Transporter, in other instances when Shipper

is unable to communicate such offer or bid via an acceptable

electronic communication mechanism. Replacement Shipper(s)

not submitting such bid electronically must submit its bid

on the Capacity Release Bid Request Form provided on

Transporter's Website under Other Information. Shipper

shall contact Transporter by telephone, prior to sending

offers of or bids on capacity release via such alternate

method, to receive a verbal confirmation of the waiver of

the electronic communication requirement and to advise

Transporter that an offer or bid via an alternate method is

forthcoming. During non-business hours, Shipper shall

contact Transporter's Nomination Center.

17.3.4 Bids and offers should be complete before being posted.

Only posted offers and bids should be available electronically.

If offers and/or bids are not submitted via an acceptable

electronic communication mechanism, as required pursuant to

Subsection 17.3.3, Transporter shall not be obligated to adhere

to the offer, match, award and/or posting provisions of

Subsection 17.3.1 and 17.3.2.

17.3.5 Capacity release facilitator should post offers and

bids, including prearranged deals, upon receipt. A Releasing

Shipper may request a later posting time for posting of such

offer, and the capacity release service facilitator should

support such request insofar as it comports with the standard

Capacity Release timeline specified in NAESB Standard 5.3.2.
