Exhibit 99.(d)(5) [MIDLAND RESOURCES, INC. LETTERHEAD] August 29, 1996 Dear Summit Shareholders, Over the past few weeks, I have had the opportunity to talk to a great number of you. There have been quite a few questions concerning the materials sent to you regarding the tender offer by Midland Resources to buy your Summit stock. Enclosed is an Amended Statement of Offer to Purchase that accomplished two important points; first, it includes additional disclosures, and second, it extends the offer until September 18, 1996. Mr. Deas H. Warley, Chairman of the Board for Midland Resources, commented, "We are making every effort possible to locate lost shareholders, as well as make it possible for all the shareholders to understand the offer." If you have not tendered your Summit stock and would like to receive a copy of the Letter of Transmittal or have any questions, please do not hesitate to call me at the number above. Sincerely, /s/ Mark A. Kahill
