10. CONVERSION

On August 1, 1993, Seller will transfer title to all top gas (less

7.2 MMDth) in storage to which Seller has title attributable to RQ and CD

service to all RQ and CD Buyers. All top gas (less 7.2 MMDth) in storage

will be allocated on a pro rata basis to the RQ and CD Buyers. Such

proration shall be determined among Buyers by determining the relative

ratio of the Buyer's Minimum Monthly Winter Requirement Quantities (for

RQ buyers) or Winter Requirement Quantities (for CD Buyers) under these

former rate schedules to the sum of all such Minimum Monthly Winter

Requirement Quantities and Winter Requirement Quantities; provided,

however, in no event shall a Buyer be allocated purchase quantities in

excess of the Buyer's MSQ as an ESS shipper. As compensation for the gas

transferred, Buyers will pay to Seller an amount reflecting Seller's cost

of such gas. Buyers may elect to reimburse Seller for such purchase

quantities in a lump sum payment or in six equal monthly payments, plus
