GENERAL TERMS AND CONDITIONS (Cont'd)
18.4 Effectiveness of Transfers. Any transfer made pursuant to Section 18.2 shall be effective on the
date a Shipper's completed nomination form is received by Transporter electronically through its EBB,
unless Transporter rejects the transfer within two business days of Transporter's receipt of such completed
nomination form pursuant to Section 18.5. Any transfer made pursuant to Section 18.3 shall be effective on
the date a Shipper's nomination to transport imbalance quantities is received by Transporter electronically
through its EBB, unless Transporter rejects the nomination prior to transportation pursuant to Section
18.5. A transfer shall become effective as of a date certain in accordance with the foregoing, and shall
have prospective, as opposed to retroactive, effect with respect to the affected accounts from that date
certain. The cumulative balance in such affected accounts shall be adjusted as of the effective date of a
transfer in accordance with the transfer.
18.5 Rejection by Transporter. Transporter may, in its reasonable discretion, reject any proposed
transfer if it determines that such transfer cannot be accommodated: (i) without diminishing Transporter's
ability to provide firm service to any Shipper; (ii) without increasing Transporter's firm service
obligations; (iii) because the gas sought to be transferred is not on Transporter's system; (iv) because of
the actual account status of the transferor's and transferee's accounts, as reflected in Transporter's
records; (v) because the transfer is requested to have a retroactive effective date; or (vi) without
