(continued)

20. OPERATIONAL CONTROLS (continued)

20.4 Miscellaneous.

(a) In exercising its authority pursuant to Section 20.3(c)

above, Transporter shall, if practicable given operating

circumstances and exigencies, generally endeavor to direct

its actions to Shippers in the following sequence, to the

extent such actions and/or sequencing will tend to alleviate

or forestall the situation to be addressed:

(i) First, to any Shipper which is causing disruption due

to its failure to maintain receipts and deliveries in

balance or to match physical flows with nominated and

confirmed receipts or nominated and scheduled

deliveries (after taking into account any storage

rights of such Shipper);

(ii) Second, to any Shipper which failed, or is failing, to

take action to anticipate a change in demand;

(iii) Third, to any Shipper which is operating in a manner

which conflicts with sound operational practices in

relation to Transporter's system;

(iv) Fourth, to all other Shippers which have significant

flexibility in volumes, receipts and deliveries; and

(v) Lastly, to all other Shippers.

(b) Notwithstanding subsection (a) above, any Shipper which has

taken voluntary action to alleviate a situation shall be

exempted from further requirements hereunder to the extent

of its voluntary action until Transporter, to the extent

practicable given operating circumstances and exigencies,

has applied equivalent measures to other Shippers.
