Item 1.01  Entry Into a Material Definitive Agreement

         On January 20, 2005, as previously reported in a Current Report on Form
8-K dated  January 26,  2005,  the Board of  Directors  of Natural Gas  Services
Group,  Inc., or Natural Gas, appointed Stephen C. Taylor as President and Chief
Executive  Officer  of  Natural  Gas.  Since  the date of his  appointment,  Mr.
Taylor's  employment has been governed by a verbal arrangement with Natural Gas.
On August 24, 2005,  Natural Gas and Mr. Taylor reduced their verbal arrangement
to a written Employment Agreement (the "Employment  Agreement"),  containing the
following terms:

         o        an annual base salary of $155,000.00;

         o        an  annual  bonus  of up to 45% of Mr.  Taylor's  annual  base
                  salary,  the amount of which will be based on parameters to be
                  established by our compensation  committee and approved by the
                  Board of Directors and the compensation committee;

         o        four weeks of vacation each year;

         o        $32,500.00 allowance to purchase a company vehicle;

         o        moving expense  reimbursement of up to $20,000.00 to cover the
                  cost  and  expenses  of  packaging  and  moving  Mr.  Taylor's
                  household goods from Houston to Midland, Texas;

         o        reimbursement for the regularly  scheduled  mortgage payments,
                  including taxes and insurance, made by Mr. Taylor with respect
                  to his residence in Houston,  Texas, during the months of May,
                  June and July 2005;

         o        standard  medical  and other  benefits  provided to all of our
                  employees.

         o        the Employment Agreement is for an initial term of three years
                  commencing  August 24,  2005,  subject to earlier  termination
                  upon the occurrence of: (a) a "fundamental change," as defined
                  in Section 2 of the  Employment  Agreement;  (b) the mental or
                  physical  incapacity or inability of Mr. Taylor to perform his
                  duties for a consecutive  period of one hundred twenty days or
                  a non-consecutive period of one hundred eighty days during any
                  twelve  month  period;  (c) the death of Mr.  Taylor;  (d) the
                  voluntary  resignation or retirement of Mr. Taylor; or (e) the
                  termination  of Mr.  Taylor's  employment  for  "cause" as set
                  forth in Section 5(a)(ii) of the Employment Agreement;

         o        if Mr.  Taylor's  employment  is terminated as the result of a
                  fundamental  change or for any reason  other than as described
                  in (b), (c), (d) or (e)  preceding,  Mr. Taylor is entitled to
                  receive a severance  benefit from Natural Gas,  which  benefit
                  includes,  among other things,  a single lump sum cash payment
                  equal to 200% of Mr.  Taylor's base salary as in effect at the
                  date of Mr. Taylor's termination of employment; and




                                       2


         o        the Employment Agreement imposes various restrictive covenants
                  on Mr. Taylor  throughout the term of his employment,  as well
                  as  post-employment   non-competition   and   non-solicitation
                  covenants.

The  foregoing  summary  is  qualified  in  its  entirety  by  reference  to the
Employment  Agreement,  a copy of which is included with this Current  Report on
Form 8-K as Exhibit 10.1

         In connection with the Employment Agreement, Natural Gas entered into a
Nonstatutory  Stock Option  Agreement  (the "Stock Option  Agreement")  with Mr.
Taylor.  The Stock Option  Agreement  grants to Mr. Taylor a ten-year  option to
purchase  45,000 shares of our common stock at an exercise  price equal to $9.22
(the fair  market  value of our common  stock on January 13,  2005,  the date we
initially hired Mr. Taylor), subject to the following vesting schedule:

         o        15,000 shares vest on January 13, 2006;

         o        15,000 shares vest on January 13, 2007; and

         o        15,000 shares vest on January 13, 2008.

The option fully vests upon the occurrence of any of the following:

         o        termination  of  Mr.  Taylor's   employment  for  any  of  the
                  following  reasons:  (a)  incapacitation  of Mr.  Taylor;  (b)
                  retirement of Mr. Taylor;  (c) death of Mr. Taylor; or (d) for
                  any other reason, unless Mr. Taylor is terminated for "cause,"
                  as defined in Section 7 of the Stock Option Agreement; or

         o        upon the occurrence of a  "fundamental  change," as defined in
                  Section 8 of the Stock Option Agreement.

The  option  expires  ten  years  from  the  date  of  grant.  The  option  is a
nonstatutory  stock  option  issued  by  Natural  Gas  pursuant  to its  general
corporate powers. Because the option is not being issued pursuant to an existing
plan,  the income  recognized  by Mr. Taylor upon exercise of the option will be
taxed at a rate equal to Mr.  Taylor's then applicable  federal  ordinary income
tax rate. Under the Stock Option Agreement,  however,  Mr. Taylor is entitled to
receive a gross-up payment from Natural Gas in an amount sufficient to place Mr.
Taylor in the same  after-tax  position  Mr.  Taylor would have been in had such
income been taxed at the then  applicable  federal  capital gains tax rate.  Mr.
Taylor is  responsible  for all additional tax due with respect to such gross-up
payment.

         The foregoing summary regarding the Stock Option Agreement is qualified
in its entirety by reference to the Stock Option  Agreement,  a copy of which is
included with this Current Report on Form 8-K as Exhibit 10.2.

         On August 26, 2005,  Natural Gas issued a press  release  regarding the
Employment Agreement and the Stock Option Agreement. A copy of the press release
is filed herewith as Exhibit 99.1.
