RATE SCHEDULE OSS (Continued)

OFF-SYSTEM STORAGE SERVICE

5.4 In any Month, should Transporter incur any charges as set forth in

Section 5.2(d) herein ("Unrecovered OSS Costs"), then all such

Unrecovered OSS Costs will be summed by Transporter for that

Month. Shipper will be responsible for its pro rata share of the

Unrecovered OSS Costs incurred by Transporter in that Month,

whereby Shipper's pro rata share will be defined as the percentage

of Shipper's OSS MSQ for that Month divided by the sum of the

total OSS MSQ of all Shippers in that Month. The Unrecovered OSS

Costs will be invoiced to Shipper on the same monthly invoice as

the charges set forth in Section 5.2 herein and will be subject to

the same terms and conditions as set forth in Transporter's

Tariff.

5.5 Shipper shall have the option to verify any modified rates or

charges imposed by Third-Party on Transporter pursuant to Section

5.2(d) herein, subject to the provisions of this Section 5.5.

Upon request of Shipper, Transporter will supply for Shipper's

review any documentation reasonably required by Shipper to verify

any change in the existing rates for service, or any charges not

supported by existing rates for such service as may exist from

time-to-time. The costs associated with any verification of rates

or charges contemplated in this Section 5.5 will be the

responsibility of Shipper.

5.6 Should Transporter receive any credits or rate reductions (to the

extent not already reflected in a reduction in the Shipper's

charges or fees) from Third-Party that are associated with Rate

Schedule OSS charges or fees for which Shipper has previously

paid, then Transporter agrees to apply any such credits or

reductions to Shipper's next monthly invoice immediately following

Transporter's receipt of any such credit. Shipper's share of any

such credit or reductions to be applied by Transporter will be

based upon the percentage calculated by (i) the total fees and/or

charges originally paid by Shipper that relate to the credit or

reduction received by Transporter; divided by (ii) the total fees

and/or charges paid by all Shippers that relate to the credit or

reduction received by Transporter.
