3. Both parties agree that the gas to be transported hereunder

shall be delivered and redelivered at uniform hourly and daily rates of

flow as nearly as practicable, but it is recognized that due to operating

conditions, the delivery and redelivery of gas may not be at the exact

same quantities each day. For this reason, it is agreed that the

quantity of gas redelivered by Natural on each day hereunder may vary

above or below the quantity received from or for the account of South

Texas. The parties however, shall use their best efforts to avoid any

variations in deliveries and redeliveries. Following receipt of monthly

statements, the parties shall adjust the redeliveries of gas each month

in order to balance any excess or deficiency on an Mcf for Mcf basis. In

the event the quantities of gas delivered and redelivered are not in

balance at the end of the term hereof, then such balance shall be

achieved within thirty (30) days by extending deliveries or redeliveries,

as applicable, at the point of delivery or point of redelivery until such

balance is achieved or by such other method as is then mutually agreed

upon by the parties hereto.
