3. TERMS AND CONDITIONS (continued)

3.4 Shipper shall make all necessary arrangements separately upstream

of the point where Gas is tendered to Transporter. Shipper is

also responsible for all arrangements downstream of the Delivery

Point(s). Such arrangements must be consistent with this Rate

Schedule RSS and must be coordinated with Transporter, subject to

the no-notice aspects of the service being provided under the RSS

Service Agreement. To be eligible for service hereunder, Shipper

or its supplier or purchaser must comply with all applicable

provisions of any separate transportation Agreement(s) and any

applicable Rate Schedule(s) and the applicable General Terms and

Conditions of this Tariff.

3.5 Shipper must provide Gas for injection by the end of the Reverse

Injection Period sufficient to replace Gas withdrawn during the

prior Reverse Withdrawal Period, as set out in Section 2.3 of this

Rate Schedule RSS. Shipper must have an RSS Balance of zero at the

end of the term of a RSS Service Agreement. If at any time

service pursuant to this Rate Schedule RSS and/or a RSS Service

Agreement is canceled or terminates prior to the end of the term

specified in the RSS Service Agreement, Shipper shall be required

to eliminate any then-remaining RSS Balance over a period of time

determined by dividing: (a) the RSS Balance, by (b) fifty percent

(50%) of Shipper's MDWQ. If Transporter is unable to accept any

volume tendered by Shipper, up to fifty percent (50%) of Shipper's

MDWQ, the period shall be extended accordingly.
