months ended June 30, 2003 increased 9% to $5,564,560, as compared to $5,119,556

same period in 2002.  EBITDA  increased 11% to  $1,863,982  for six months ended
June 30, 2003 versus $1,679,112 for the same period in 2002.

Company ended the quarter with 353 compressor  packages in its rental fleet,  up
from 254 units at June 30, 2002 and 308 units at December 31, 2002.

Wayne Vinson,  President and CEO of Natural Gas Services  Group,  Inc. said, "We
are extremely pleased with our quarter-to-quarter growth. With a 67% increase in
revenue for the three  months and 53%  increase in revenue for the six months in
our core leasing  business,  the second quarter and six months were  significant
accomplishment  for Natural Gas Services Group. As the second quarter  financial
results show, our core leasing business remains quite  profitable.  We have been
able to do this by  delivering  a  high-value  product to the small to mid-sized
compressor market that meets their critical needs.  Historically,  our equipment
utilization rate remains around 90% and our operating margins are well above the
industry  norms.  As we move into our third  quarter we will  continue  with our
strategic  initiatives.  While the economy  continues to firm up, our goal is to
continue to meet the market demand for our products."

"EBITDA"  reflects net income or loss before interest,  taxes,  depreciation and
amortization. EBITDA is a measure used by analysts and investors as an indicator
of  operating  cash flow since it excludes  the impact of  movements  in working
capital items, non-cash charges and financing costs. Therefore, EBITDA gives the
investor information as to the cash generated from the operations of a business.
However,  EBITDA is not a measure  of  financial  performance  under  accounting
principles  generally  accepted in the United  States of America  ("GAAP"),  and
should  not  be  considered  a  substitute  for  other  financial   measures  of
performance.  EBITDA as  calculated  by NGS may not be  comparable  to EBITDA as
calculated and reported by other companies.  The most comparable GAAP measure to
EBITDA is net income. The reconciliation of EBITDA to net income is as follows:
