ONEOK acquired the Bushton gas processing plant and related leases from Kinder Morgan in April 2000. Kinder Morgan had previously acquired the plant and leases from Enron. The technical default resulted from the bankruptcy filing by Enron, which is a guarantor of the leases in addition to Kinder Morgan and ONEOK. The waiver satisfies any concern related to the technical default. ONEOK will continue to make all payments due under the leases.
