GENERAL TERMS AND CONDITIONS

(continued)

5.4 In the event that batch flowing nominated volumes less than 5,000

MMBTU per day is deemed operationally impractical by Transporter or

Petal, and should Petal receive nominations for the injection or

withdrawal of gas, which after aggregation with other nominations

commencing at the same time and same meter, results in a net metered

volume less than or equal to 5,000 MMBtu per day, Petal will attempt

to schedule such nominations on a "best efforts" basis. However, if

any single or combination of nominations is scheduled such that the

aggregated nominated volumes result in a net metered volume less than

or equal to 5,000 MMBtu per day, all nominations may be curtailed on

a

pro-rata basis such that the net metered volume will be zero. Petal

will verbally notify the affected Customer(s) within four (4) hours of

being notified of changes to nominations which would result in

curtailment as provided herein.

6. SCHEDULING

6.1 Petal shall accept nominations 24 hours a Day during any day when

Customer desires Petal to receive and inject gas into, or to withdraw

and deliver gas from storage, Customer shall submit a nomination via

fax or Petal's EBB, that includes but is not limited to the following

information: daily volume, flow period (Customer defined begin dates

and end dates), upstream transportation contract number(s) (for

injections), downstream transportation contract number(s) (for

withdrawals), customer name and contract number, the customer's

authorized employee name and telephone number, the type of service

desired, for injections, the State of the source of gas, and for

customers obtaining released capacity from a capacity holder other

than Petal, the name of that capacity holder. All nominations

excluding intra-day nominations shall have roll-over options.

Specifically, customers shall have the ability to nominate for several

days, months, or years, provided the nomination begin and end dates

are within the term of Customer's contract. All nominations should be

considered original nominations and should be replaced to be changed.

When a nomination for a date range is received, each day within that

range is considered an original nomination. When a subsequent

nomination is received for one or more days within that range, the

previous nomination is superseded by the subsequent nomination only to

the extent of the days specified. The days of the previous nomination

outside the range of the subsequent nomination are unaffected.

Nominations have a prospective effect only. Overrun quantities should

be requested on a separate transaction.

control of the nominating party; 11:45 a.m. for receipt of nominations by
