penalties determined pursuant to Article 9 of the General Terms

and Conditions.

5. AUTHORIZED OVERRUN DELIVERIES

Service under this rate schedule on any day shall not exceed the MDTQ

within each area, MDIQ, MSQ, MDWQ, or the individual MDQ's for each

delivery point within such area; provided, however, WNG may, at the

request of Shipper, receive, store, transport and deliver on any day

quantities in excess of the MDTQ, MDIQ, MDWQ or of the individual

MDQ's within each area when, and to the extent, in WNG's reasonable

judgment, the delivery capacity of its system so permits without

impairing the ability of WNG to meet its full delivery obligations to

any of its firm service customers. The applicable maximum and minimum

rate for any such overrun deliveries shall be as stated on effective

Tariff Sheet No. 6 or 6A, and absent a specific agreement specifying a

discounted rate, the maximum rate shall apply. Such Authorized

Overrun Deliveries shall be subject to the same operating terms and

conditions as are extended to service provided under Rate Schedule ITS

and ISS and shall not interrupt flowing STS, TSS, FSS, SFT and FTS

service; provided, however, that Authorized Overrun Service shall have

a lower priority for scheduling and curtailment purposes than service

under Rate Schedules ITS and ISS. The authorized overrun charge shall

only be charged if the MDWQ, MDIQ, MSQ, or the MDTQ for any area is

exceeded under any service agreement.

6. STORAGE OPERATIONS

The FSS component part of this rate schedule shall be subject to the

terms and provisions of Rate Schedule FSS Sections 2 and 3.
