HILAND PARTNERS, LP AGREES TO ACQUIRE HILAND PARTNERS, LLC FOR $95 MILLION Enid, Oklahoma - September 12, 2005 - Hiland Partners, LP (NASDAQ: HLND) (the "Partnership") announced today that Hiland Operating, LLC, a wholly-owned subsidiary of the Partnership, has signed a definitive purchase agreement to acquire the outstanding membership interests in Hiland Partners, LLC for $95 million in cash, subject to certain closing adjustments. Hiland Partners, LLC, an affiliate of the Partnership, owns the Bakken Gathering System located in Richland County, Montana. In connection with this acquisition, the Partnership will increase the size of its bank revolving credit facility from $55 million to $125 million to facilitate closing of the acquisition. This increased facility will fund concurrently with the closing of the acquisition. The purchase price will be funded from proceeds of the increased facility. The Partnership anticipates the acquisition will close in the third quarter of 2005, subject to customary closing conditions including regulatory approvals. The acquisition will have an effective date of September 1, 2005. Pursuant to an option contained in an omnibus agreement the Partnership entered into with Hiland Partners, LLC and Harold Hamm and his affiliates in connection with the Partnership's initial public offering, Hiland Partners, LLC granted the Partnership an exclusive two-year option to purchase its Bakken Gathering System (a greenfield gathering system) at fair market value at the time of purchase. A mutually-agreed-upon investment banking firm determined the fair market value of the Bakken Gathering System and the Partnership's Conflicts Committee, consisting of its independent directors, approved the valuation. As of August 31, 2005, the Bakken Gathering System consisted of approximately 250 miles of gas gathering pipeline, a processing plant, two compressor stations, which are comprised of three units with an aggregate of approximately 4,434 horsepower, and one fractionation facility. The Bakken processing plant and a portion of the gathering system became operational on November 8, 2004 and the system's peak throughput rate during the month of August 2005 was 13.0 MMcf/d. The gathering system has an initial capacity of approximately 21.0 MMcf/d. During the second quarter of 2005, the Bakken Gathering System achieved revenue and earnings before interest, taxes, depreciation and amortization ("EBITDA") of $6.7 million and $1.3 million, respectively, on natural gas throughput volumes of 8.0 MMcf/d. EBITDA is a non-GAAP financial measure that is reconciled to its most directly comparable GAAP measure at the end of this press release. "We expect the acquisition to be immediately accretive to distributable cash flow based on Bakken's expected annualized EBITDA run rate exceeding $14 million as of the anticipated closing date," stated Randy Moeder, President and Chief Executive Officer of the Partnership. As a result of the acquisition, management is reviewing with its Board of Directors the appropriate level of future cash distributions. Management anticipates that it will recommend to the Board of Directors an increase in the annual distribution rate, which is currently $1.85 per unit, to at least an annual rate of $2.35 per unit (an increase of $0.50 per unit) beginning with the distribution for the first full quarter following closing.
