GENERAL TERMS AND CONDITIONS

(Continued)

6.4(c) (continued)

(ii) The next quantities scheduled shall be those quantities

required to meet Transporter's firm storage Shippers'

Nominated quantities. If capacity is not available to

serve all such firm Nominations, the available capacity

shall be allocated pro rata based upon Shipper's

MDIQ/YMDIQ/TMDIQ or ADWQ/YADWQ/TADWQ, as appropriate.

(iii) The next quantities scheduled shall be those quantities

required to meet Transporter's interruptible storage

Shippers' Nominated quantities.

1. Injections shall be scheduled as follows:

Quantities to which higher rates are applicable

shall be scheduled before quantities to which lower

rates are applicable. Nominations of quantities to

which a higher rate is applicable shall be fully

satisfied before any Nominated quantities to which

a lower rate is applicable are scheduled. Where the

rate is the same and capacity is not available,

service shall be pro rata based on quantities

Nominated.

2. Withdrawals shall be scheduled on a pro rata 1/

basis, provided however, that no Shipper shall

receive capacity in excess of that Shipper's

Nomination. If any Shipper's pro rata share exceeds

the quantity Nominated on any Day by that Shipper,

the difference between the pro rata share and the

Nominated quantity shall be shared pro rata 1/

among Shippers Nominating quantities in excess of

their pro rata shares. A Shipper who does not

Nominate quantities equal to its pro rata share on

any Day may Nominate quantities equal to its pro

rata share on any subsequent Day of the Month, and

Transporter shall schedule such quantities.

1/ For purposes of scheduling of withdrawals from storage only, a

Shipper's pro rata share shall equal that Shipper's total quantity

of Gas in Place (G.P.) divided by the total G.P. under Rate Schedule

IS-1, Rate Schedule IS-T or Rate Schedule IS-Y as of the most

current Day allocated.
