              HILAND PARTNERS, LP REPORTS FIRST QUARTER RESULTS

    ENID, Okla., May 12 /PRNewswire-FirstCall/ -- Hiland Partners, LP (Nasdaq:
HLND) (the "Partnership") today reported quarterly net income for the three
months ended March 31, 2005 of $1.6 million compared to net income of $0.8
million for the three months ended March 31, 2004, an increase of 113%. EBITDA
for the three months ended March 31, 2005 was $3.7 million compared to $1.8
million for the three months ended March 31, 2004, an increase of 102%. Total
segment margin for the three months ended March 31, 2005 was $5.6 million
compared to $3.2 million for the three months ended March 31, 2004, an increase
of 72%. This increase is primarily attributable to higher average realized
natural gas prices and NGL sales prices and inclusion of the results of
operations from the assets acquired from Hiland Partners, LLC on February 15,
2005.

    The financial position and results of operations for the three-month period
ended March 31, 2005 include the financial results of Continental Gas, Inc. (our
predecessor) through February 14, 2005. The financial results also include 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, operating
income and volumes are not comparable on a period-to-period basis.

    For the period from February 15, 2005, inception of operations, to March 31,
2005, the Partnership reported quarterly net income of $1.1 million ($0.16 per
basic and diluted limited partners unit) and EBITDA of $2.5 million. The
Partnership commenced operations February 15, 2005 upon successful completion of
its initial public offering and the concurrent contribution of certain assets
from its predecessor entity and certain assets acquired from Hiland Partners,
LLC.

    On April 25, 2005, the Partnership announced a cash distribution for the
first quarter of 2005 of $0.225 per unit, based on the minimum quarterly cash
distribution of $0.45 prorated for the period since inception of operations,
February 15, 2005, payable on all common, subordinated and general partner
units. The pro rata distribution declared for the quarter of $0.225 on all units
totals to $1.6 million.

    "I am pleased with our first quarter results," said Randy Moeder, President
and Chief Executive Officer of Hiland Partners, LP. "Our near-term focus
continues to remain on organic growth. To that end, I am pleased to announce
that the Partnership has provided written notice to the owners of the Bakken Gas
Plant and Gas Gathering System advising of our intent to exercise the option to
purchase the system in accordance with the terms of the purchase option that the
Partnership has on this facility. If the parties are able to reach an agreement
on the purchase price, the transaction will have to be approved by the
independent members of our General Partner's Board of Directors."

        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 a 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.
        Our compression segment margin will equal the fee we will earn under our
        Compression Services Agreement with Continental Resources, Inc. for
        providing air compression and water injection services. The fee that we
        will earn under this agreement will be fixed as long as our facilities
        meet specified availability requirements, regardless of Continental
        Resources, Inc.'s utilization. As a result, our compression segment
        margin will be dependent on our ability to meet their utilization
        levels.

    (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. EBITDA is used as a supplemental
        financial measure by our management and by external users of our
        financial statements such as investors, commercial banks, research
        analysts and others to access: (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 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 facilities.
