Commission File No.: 1-3523 ---------------------------------------------------- Subject Company: Western Resources, Inc. PNM Interoffice Correspondence TO: All Employees July 26, 2001 FROM: Jeff Sterba Chairman, President and CEO RE: Discussions Regarding Possible Modifications to Western Deal Today, in a joint media release with Western Resources, we announced our belief that if recent orders by the Kansas Corporation Commission (KCC) remain in effect, the proposed transaction to acquire Western and combine the companies' electric operations will be difficult to complete as currently structured. Yesterday, the KCC issued an order that would reduce Western's rates by $22.7 million. Last Friday, the commission ordered Western to halt its corporate restructuring efforts. We don't believe that the split-off and other transactions envisioned in our Merger Agreement with Western Resources can be accomplished on the agreed terms if the KCC's orders remain in effect. I continue to believe in the strategic benefits of bringing our two companies together. We are hopeful a transaction can be structured that would benefit customers and shareholders of both companies and could obtain the approval of necessary regulatory authorities, including those in Kansas and New Mexico. Over the next several weeks we will meet with Western officials to discuss modifications to the transaction that will make it possible to obtain necessary regulatory approvals.
