entire term of an Agreement.

2.4 Compliance with Reservoir Integrity Inventory Limit.

(a) Shipper shall not exceed the Reservoir Integrity Inventory

Limit as provided in Section 1 of the General Terms and

Conditions. If Shipper exceeds the Reservoir Integrity

Inventory Limit, Transporter will seek Shipper's immediate

cooperation to bring Shipper's Gas in Place into compliance

with the Reservoir Integrity Inventory Limit. If necessary,

Transporter will issue Operational Flow Orders to bring

Shipper's Gas in Place into compliance with the Reservoir

Integrity Inventory Limit. Shipper's MDWQ shall be reduced

pursuant to the ADWQ chart provided in Section 1 of the General

Terms and Conditions. Shipper shall hold Transporter harmless

and shall indemnify Transporter for any damages which may

directly or indirectly arise out of or which relate to

Shipper's failure to maintain a sufficient quantity of Gas as

in storage to satisfy its needs.

(b) Shipper shall have no more than 24 percent of MAC in storage

between and including May 1 and May 15 of each year, unless

Transporter determines, on a non-discriminatory basis, that

retention of a higher quantity of Gas will not adversely affect

Transporter's storage reservoirs. In such instance, Transporter

shall specify the higher level Shipper may maintain.

Limit in Section 1 of the General Terms and Conditions,

Transporter shall evaluate its storage reservoirs each year to

determine if Shipper can be authorized to maintain a higher

inventory level in storage during the following withdrawal and

injection seasons. Transporter shall base this evaluation on

actual storage usage during the previous year and shall post

the revised requirements (Variable Reservoir Integrity

Inventory Limits) on its electronic bulletin board on or before

January 21 of each year.

(d) The above requirements notwithstanding, 100 percent of all

quantities stored hereunder shall be withdrawn upon expiration

of the term of the Agreement.
