<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On December&nbsp;20, 2006, the Compensation Committee of the Board of Directors of Natural Gas
Services Group, Inc. voted to grant to each of the seven non-employee members of the Company&#146;s
Board of Directors a regular annual stock option (collectively, the &#147;Non-Employee Director
Options&#148;) to purchase up to 2,500 shares of the Company&#146;s common stock. The Company reported the
Board of Directors&#146; approval of such options and certain other events in a Form 8-K dated December
19, 2006, and filed with the Securities and Exchange Commission on December&nbsp;22, 2006 (the &#147;December
22, 2006 Form 8-K&#148;).
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The December&nbsp;22, 2006 Form 8-K reported that the Non-Employee Director Options would be
granted on December&nbsp;29, 2006 and would be exercisable for a term of 10&nbsp;years from the date of
grant, subject to earlier termination pursuant to the terms of the standard non-statutory stock
option agreement under the Company&#146;s 1998 Stock Option Plan, amended. On January&nbsp;15, 2007, the
Compensation Committed unanimously consented to an amendment to the Non-Employee Director Options,
the effect of which was to make such options exercisable for a term of 10&nbsp;years from January&nbsp;1,
2007, rather than from the date of grant. This Form 8-K/A amends the December&nbsp;22, 2006 Form 8-K to
reflect that the Non-Employee Director Options shall be exercisable for a term of 10&nbsp;years from
January&nbsp;1, 2007, subject to earlier termination pursuant to the terms of the standard non-statutory
stock option agreement under the Company&#146;s 1998 Stock Option Plan, amended.
