                HILAND PARTNERS, LP REPORTS FIRST QUARTER RESULTS

    ENID, Okla., May 11 /PRNewswire-FirstCall/ -- Hiland Partners, LP (Nasdaq:
HLND) (the "Partnership") today reported quarterly net income for the three
months ended March 31, 2006 of $3.6 million compared to net income of $1.6
million for the three months ended March 31, 2005, an increase of 117%. Net
income per limited partner unit for the first quarter of 2006 increased to $0.37
per unit from income of $0.16 per unit in the corresponding quarter in 2005, an
increase of 131%. Adjusted EBITDA (adjusted EBITDA is defined as net income plus
interest expense, provisions for income taxes and depreciation, amortization and
accretion expense, as adjusted for non-cash realized (gain) loss on derivative
transactions and non-cash unit based compensation expense) for the three months
ended March 31, 2006 was $8.4 million compared to $3.7 million for the three
months ended March 31, 2005, an increase of 129%. Total segment margin for the
three months ended March 31, 2006 was $11.9 million compared to $5.6 million for
the three months ended March 31, 2005, an increase of 113%. The increases are
primarily attributable to higher average realized natural gas and NGL sales
prices and the inclusion of the results of operations from the assets
contributed to us by Hiland Partners, LLC (the Worland gathering system and
compression assets) as part of our initial public offering on February 15, 2005
and the acquisition of Hiland Partners, LLC (the Bakken gathering system)
effective September 1, 2005.

    Our financial results for the quarter ended March 31, 2006 include the
acquisition of the membership interests of Hiland Partners, LLC (the Bakken
gathering system) effective on September 1, 2005. The results of operations for
the quarter ended March 31, 2005 include the financial results of Continental
Gas, Inc. (our predecessor) through February 14, 2005 and the results of
operations of Hiland Partners, LP for the period from February 15, 2005, the
date Hiland Partners, LP commenced operations. As a result, our results of
operations are not comparable on a period-to-period basis.

    "We are pleased with our first quarter results and the continued growth of
the Bakken gathering asset that allows us to continue our distribution growth,"
said Randy Moeder, President and Chief Executive Officer of Hiland Partners, LP.
"As we look forward this year, we expect to see that growth continues with the
acquisition of the Kinta area gathering assets from Enogex and with the
implementation of the other organic growth projects previously announced for
2006."

    On April 26, 2006, the Partnership announced an increase in its cash
distribution for the first quarter of 2006. The declared quarterly distributions
on the Partnership's common and subordinated units increased from $0.625 per
unit (an annualized rate of $2.50 per unit) for the fourth quarter of 2005, to
$0.65 per unit (an annualized rate of $2.60 per unit) for the first quarter of
2006. This distribution will be payable on May 15, 2006 to unitholders of record
on May 5, 2006.

    We view total segment margin, a non-GAAP financial measure, as an important
performance measure of the core profitability of our operations. We review total
segment margin monthly for consistency and trend analysis. We define midstream
segment margin as midstream revenue less midstream purchases. Midstream
purchases include the following costs and expenses: cost of natural gas and NGLs
purchased by us from third parties, cost of natural gas and NGLs purchased by us
from affiliates, and cost of crude oil purchased by us from third parties. We
define compression segment margin as the revenue derived from our compression
segment.

     (F) We define EBITDA, a non-GAAP financial measure, as net income plus
interest expense, provisions for income taxes and depreciation, amortization and
accretion expense. We define adjusted EBITDA, a non-GAAP financial measure, as
net income plus interest expense, provisions for income taxes and depreciation,
amortization and accretion expense, as adjusted for non-cash realized (gain)
loss on derivative transactions and non-cash unit based compensation expense.
EBITDA and adjusted EBITDA are used as supplemental financial measures by our
management and by external users of our financial statements such as investors,
commercial banks, research analysts and others to assess: (1) the financial
performance of our assets without regard to financial methods, capital structure
or historical cost basis; (2) the ability of our assets to generate cash
sufficient to pay interest costs and support our indebtedness; (3) our operating
performance and return on capital as compared to those of other companies in the
midstream energy sector, without regard to financing or structure; and (4) the
viability of acquisitions and capital expenditure projects and the overall rates
of return on alternative investment opportunities. EBITDA is also a financial
measurement that, with certain negotiated adjustments, is reported to our banks
and is used as a gauge for compliance with our financial covenants under our
credit facility. EBITDA and adjusted EBITDA should not be considered as
alternatives to net income, operating income, cash flows from operating
activities or any other measures of financial performance presented in
accordance with GAAP. Our EBITDA and adjusted EBITDA may not be comparable to
EBITDA and adjusted EBITDA of similarly titled measures of other entities, as
other entities may not calculate EBITDA and adjusted EBITDA in the same manner
as we do.
