ONEOK REPORTS ENRON EXPOSURE

         Tulsa--ONEOK, Inc., (NYSE:OKE) today announced that its net exposure to
Enron based on New York Mercantile Exchange (NYMEX) futures prices at the close
of business on Thursday, November 29, 2001, is less than $40 million pre-tax.
This exposure is based on commodity transactions primarily for storage
management and natural gas production hedges involving its energy marketing and
trading and production segments.

         ONEOK continues to pursue ways to mitigate this exposure, however,
should Enron fail to perform its obligations, ONEOK's current net delivered
physical commodity exposure is estimated to be less than four million dollars.
The financial exposure due primarily to storage management and natural gas
production are approximately $36 million.

         If Enron performs its current obligations the total exposure would drop
to less than two million dollars pre-tax after January 4, 2002. There are no
amounts past due from Enron at the current time.

         Chris Skoog, president of ONEOK Energy Marketing and Trading, said, "We
are taking all precautions to limit our exposure under the circumstances and we
believe there will be opportunities resulting from this difficult situation. Our
strategy of focusing on trading around physical assets puts us in a great
position to take advantage of the emerging opportunities."
