GENERAL TERMS AND CONDITIONS

32. Discounts.

Types of Discounts. Overthrust may agree, in writing, to allow a

variety of discounts between its maximum and minimum rates under any rate

schedule in its tariff without undue discrimination. Such discounts may be

in addition to a base discount and will not be considered a material

deviation from Overthrust's forms of service agreements when Overthrust and

Shipper agree that a discount applies. Categories of eligible discounts are

as follows:

1. Specified quantities under shipper's service agreement.

2. Quantities above or below a certain level or all quantities if

quantities exceed a certain level.

3. A specified relationship to quantities actually transported or

stored.

4. During specified periods of the year or over specifically defined

periods of time.

5. Specific receipt points, delivery points, zones, pooling areas,

transportation routes, markets or other defined geographic areas, or for

specific direction of gas flow.

6. Alternate receipt points under shipper's contract when shipper

currently has a discount under the contract's primary receipt point.

7. Production reserves, gas supplies or markets committed by a

shipper.

8. To achieve an agreed-upon, overall effective rate, with a

provision for adjusting the rate components of discounted agreements, if

needed, to preserve the agreed-upon overall effective rate, so long as all

rate components remain within the applicable minimum and maximum rates

specified in the tariff. This provision may apply when a FERC-mandated

change in Overthrust's Statement of Rates affects the current rate paid by

shipper under a transportation service agreement. The parties may negotiate

a rate that as nearly as possible preserves shipper's contractual rate,

commencing with the approved Statement of Rates. However, nothing contained

herein shall be construed to alter a refund obligation under applicable law

for any period during which rates that had been charged under a discount

agreement exceeded rates which ultimately are found to be just and

reasonable.

9. Quantities conditioned upon implementation and completion of a

construction project or acquisition of facilities.
