TRANSPORTATION GENERAL TERMS AND CONDITIONS
                              (Continued)
   
     3.   Required Nomination changes - If estimated daily flows under a
particular Service agreement differ from the confirmed nominations, or if an
imbalance has occurred due to some other reason, then prospective nomination
change(s) (either receipt or delivery adjustments) may be required to bring
the receipt and delivery volumes into balance.  When a Shipper receives
notification of a required change in the nomination, the Shipper shall be
responsible for informing upstream and downstream parties of the prospective
change and providing MIGC with a nomination as required in accordance with
Section 4.2 hereof.
   
     4.   Confirmation by MIGC - Nominations made in accordance with
Sections 4.2, 4.3, 4.5, and 4.6 hereof shall not become effective until MIGC
has confirmed the nominated receipts and deliveries with upstream and
downstream parties.  Receiver of nomination initiates confirmation process.
The Confirming Party that would receive a Request for Confirmation or an
unsolicited Confirmation Response may waive obligation of sender to send
(Standards Board Standard 1.3.20).  For request to confirm and confirmation
response processes, all parties will seek to confirm by means of communicating
at the applicable detail/summary level all transactions with respect to a
location (Standards Board Standard 1.3.35).  Shipper shall designate the
appropriate person(s) who has the authority to resolve allocation issues if
required by MIGC and, if required by MIGC, the appropriate person(s) to
confirm nominations.
   
     In the confirmation process, where a party requesting a confirmation (a
Confirmation Requester) is not itself a Transportation Service Provider, the
location code to be used when sending a Request for Confirmation should be the
location code associated with the location where gas will be scheduled by the
Transportation Service Provider; and, where a Confirmation Requester is also
a Transportation Service Provider; then, as between these confirming parties
(the Confirmation Requester and the Confirming Parties), and absent their
mutual agreement to the contrary, the location code to be used when sending a
Request for Confirmation should be the location code used by the
Transportation Service Provider sending the Request for Confirmation
(Standards Board Standard 1.3.36).
