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.
