tive Imbalance Cash-Out Price (set forth at Section 14.10(a)

3.3 (a) Upon Transporter's determination that Shipper's request for

service is complete, Transporter will enter such request on

a list of pending complete requests and so notify shipper.

Transporter will evaluate its ability to satisfy complete

requests for service received in their order of entry on

such list. Transporter shall process requests for service

within a reasonable period of time. If Transporter rejects

a request for service which has been entered on Trans-

porter's list of pending complete requests, Transporter will

so notify Shipper within ten (10) days of such rejection.

In such event, Shipper's request for service will not remain

entered on such list unless Shipper notifies Transporter,

within thirty (30) days of Transporter's notification of

rejection, that its request should remain so entered. Upon

receipt of such written notification by Shipper, Shipper's

request will remain entered for an additional six (6)

months, and for additional three (3) month periods thereaf-

ter, provided that Shipper notifies Transporter, in writing,

prior to the conclusion of a three (3) month period, that it

requests an extension.

(b) An IAS Service Agreement shall be executed by Shipper and

Transporter following Transporter's acceptance in writing of

Shipper's request for service. In the event the IAS Service

Agreement is not executed and returned by Shipper within

thirty days after Transporter tendered the agreement, Trans-

porter shall consider the request for service invalid.
