Gastar Exploration Announces Results of Operations For the Quarter and
                     Year Ended December 31, 2006


    HOUSTON--(BUSINESS WIRE)--March 27, 2007--Gastar Exploration Ltd.
(AMEX:GST) (TSX:YGA) reported a net loss attributable to common shares
for the three months ended December 31, 2006 of $27.5 million, or
$0.15 per basic and diluted common share, compared to a net loss of
$4.8 million, or $0.03 per basic and diluted common share, for the
three months ended December 31, 2005. The fourth quarter 2006 loss
included an impairment of natural gas and oil properties of $19.0
million and litigation settlement expense of $742,000. Total revenues
for the three months ended December 31, 2006 were $6.8 million, a
decrease of $3.1 million, as compared to revenues of $9.9 million for
the 2005 comparable period. The decrease in 2006 quarterly revenues
was the result of a 35% decrease in prices, which was partially offset
by a 5% increase in production. Average daily production for the three
months ended December 31, 2006 was 13.7 million cubic feet of natural
gas equivalents per day ("MMcfed"), compared to 13.0 MMcfed for the
three months ended December 31, 2005. Average daily production for the
fourth quarter was flat to third quarter 2006 due to delays in the
completion of several Bossier wells. EBITDA, as defined below, for the
three months ended December 31, 2006 was $396,000, down from EBITDA of
$4.7 million for the three months ended December 31, 2005.

    Gastar reported a net loss attributable to common shares for the
year ended December 31, 2006 of $84.8 million, or $0.50 per basic and
diluted common share, compared to a net loss of $25.7 million, or
$0.20 per basic and diluted common share, for the year ended December
31, 2005. The net loss for 2006 and 2005 includes impairment of
natural gas and oil properties of $56.3 million and $8.7 million,
respectively. Year end 2006 results also included litigation
settlement expense of $2.4 million. Total revenues for the year ended
December 31, 2006 were $26.8 million, a decrease of $600,000 from
revenues of $27.4 million for the 2005 comparable period. The decrease
in 2006 revenues was the result of a 21% decrease in prices, which was
partially offset by a 23% increase in annual production. Average daily
production for the year ended December 31, 2006 was 12.9 MMcfed,
compared to 10.5 MMcfed for the year ended December 31, 2005. EBITDA
for the year ended December 31, 2006 was $3.6 million, down from $12.3
million for the year ended December 31, 2005.

    Total proved reserves as of December 31, 2006 were 31.2 billion
cubic feet of natural gas and 30,000 barrels of oil. The present value
of estimated future cash flows before income taxes as of December 31,
2006, based on the weighted average natural gas and oil prices, after
basis adjustments, of $4.76 per Mcf and $56.59 per barrel, discounted
at 10% per annum, was $40.3 million. Current year reserves were
negatively impacted by a 36% decrease in realized natural gas prices
from year end 2005 and a 10 billion cubic feet equivalent ("Bcfe")
downward revision in Gastar's Powder River Basin coal bed methane
reserves. The Powder River Basin revision was the result of lower gas
prices and basin-wide performance revisions.

    J. Russell Porter, Gastar's President and Chief Executive Officer,
made the following comment, "The fourth quarter results for 2006 were
negatively impacted by the downward revision of Powder River Basin
coal bed methane reserves and lower natural gas prices at year-end
resulting in additional non-cash ceiling impairment charges. The
downward revision overshadowed the success of our 2006 East Texas deep
Bossier results. Including positive reserve revisions related to well
performance, our 2006 deep Bossier reserves increased 86% to 21 Bcfe
after production of 2.9 Bcfe. The success of wells drilled in late
2006 and completed in 2007 was not fully recognized in our year-end
reserve estimates. The impact of these recent wells is demonstrated in
our gross sales rate for the East Texas area which has nearly doubled
since year-end. The 3-D seismic survey that was recently delivered for
processing should be available in the second quarter to better define
and high grade our Bossier drilling opportunities in the second half
of 2007."

EBITDA (in thousands) (1)          $396    $4,665    $3,606   $12,289

(1)  EBITDA represents earnings before interest expense, accretion of
      asset retirement obligations, depletion, depreciation and
      amortization, impairment of natural gas and oil properties and
      provision for income taxes. We have reported EBITDA because we
      believe EBITDA is a measure commonly reported and widely used by
      investors as an indicator of a company's operating performance
      and ability to incur and service debt. We believe EBITDA assists
      investors in comparing a company's performance on a consistent
      basis without regard to depreciation, depletion and
      amortization, impairment of natural gas and oil properties and
      exploration expenses, which can vary significantly depending
      upon accounting methods. EBITDA is not a calculation based on
      U.S. generally accepted accounting principles and should not be
      considered an alternative to net income (loss) in measuring our
      performance or used as an exclusive measure of cash flow because
      it does not consider the impact of working capital growth,
      capital expenditures, debt principal reductions and other
      sources and uses of cash, which are disclosed in our statements
      of cash flows. Investors should carefully consider the specific
      items included in our computation of EBITDA. While we have
      disclosed our EBITDA to permit a more complete comparative
      analysis of our operating performance and debt servicing ability
      relative to other companies, investors should be cautioned that
      EBITDA as reported by us may not be comparable in all instances
      to EBITDA as reported by other companies. EBITDA amounts may not
      be fully available for management's discretionary use, due to
      requirements to conserve funds for capital expenditures, debt
      service, preferred stock dividends and other commitments.

    A reconciliation of net loss to EBITDA for the periods indicated
is presented below.
