PRICING:

From time to time, Customer and Company shall negotiate a rate and term of
transportation which shall be by purchase nomination order in the form which is
attached as Exhibit A and incorporated by reference in this Agreement.

Service Qualifications:

The Company is notifying Customers who have elected Gas Transportation Service
of the risks of transportation reasonably known at the time the Customer begins
transporting gas. The Customer hereby understands it may be subject to risks
which include, but may not be limited to, the following:

         1)       The Company may not have firm or interruptible gas sales
                  service available if the Customer seeks to purchase gas from
                  the Company;

         2)       The Customer may be subject to pipeline penalties assessed to
                  the Company which are caused by the Customer consuming the
                  Company's gas with no authority to do so; and

         3)       If the Customer elects to discontinue transporting gas and if
                  the Company is able to secure a source of gas supply and
                  transportation for the Customer, the cost of such gas and
                  transportation may exceed the cost of gas being purchased by
                  the Company's other Customers.

IN WITNESS WHEREOF, the Parties hereto have executed this Service Request Form
as of the day and year set forth below.
