Item 1.01.  Entry into a Material Definitive Agreement.

         On October 18, 2004,  Natural Gas Services Group,  Inc.  entered into a
Stock Purchase Agreement with Screw Compression Systems, Inc., or "SCS", and the
stockholders of SCS. Under this agreement,  Natural Gas Services Group agreed to
purchase  from Paul D.  Hensley,  Tony  Vohjesus and Jim  Hazlett,  the "selling
stockholders", all of the outstanding shares of capital stock of SCS.

         SCS is a privately owned manufacturer of natural gas compressors,  with
its principal offices located in Tulsa, Oklahoma.

         The selling  stockholders will receive, in proportionate  shares (based
on their stock ownership of SCS), a total of $15 million, consisting of:

         o        $8 million in cash;

         o        promissory  notes  issued  by  Natural  Gas  Services  in  the
                  aggregate  principal  amount of $3 million bearing interest at
                  the rate of four  percent  (4.00%) per annum,  maturing  three
                  years  from the date of  closing  and  secured  by a letter of
                  credit in the face amount of $2 million; and

         o        609,576 shares of Natural Gas Services  common stock valued at
                  $4 million,  based on the average of the daily closing  prices
                  of the common  stock for the ninety  consecutive  trading days
                  ended April 28, 2004. All of the shares,  upon issuance,  will
                  be  "restricted"  securities  within  the  meaning of Rule 144
                  under the Securities Act of 1933, as amended,  and will bear a
                  legend to that effect.

         Under terms of the agreement,  for a period of two years  following the
closing,  the  selling  stockholders  will have the  right,  subject  to certain
limitations,  to include  or  "piggyback"  the  609,576  shares of common  stock
received  by them in the  transaction  in any  registration  statement  filed by
Natural Gas Services with the Securities and Exchange Commission.

         After the closing, SCS will be operated as a wholly owned subsidiary of
Natural Gas Services and the selling stockholders will continue in their present
positions  with SCS under  three-year  employment  agreements.  In addition,  at
closing,  Paul D. Hensley  will be  appointed to fill a vacancy  existing on the
Board of Directors of Natural Gas Services, to hold office until the next annual
meeting of  stockholders of Natural Gas Services at which directors are elected,
and in  connection  with the next annual  meeting of  stockholders,  Natural Gas
Services will nominate Paul D. Hensley for election as a director to serve for a
term the same as the class of directors then standing for election.

         Natural  Gas  Services  has  agreed to pay to  Karifico  Consultants  a
finder's fee in the amount of $150,000.

         The agreement is subject to customary closing conditions, including the
approval by the American Stock Exchange of the common stock for listing on AMEX.
Closing  under the  agreement is  scheduled to occur not later than  December 6,
2004. The agreement may be terminated by the selling stockholders or Natural Gas
Services Group if the closing does not occur by December 6, 2004.



                                        2



         Natural Gas Services Group has no material relationship with SCS or the
selling stockholders other then with respect to the Stock Purchase Agreement.

         The foregoing is a summary of the material  features of the  agreement.
This summary does not purport to be complete and is qualified in its entirety by
reference to the terms of the agreement,  which is filed as Exhibit 10.1 to this
Current Report on Form 8-K, and incorporated herein by reference.

assets (tangible and intangible)  reflected in the Company Balance Sheet, except
for (i) such  properties  and  assets  as are no  longer  used or  useful in the
conduct of its businesses or as have been disposed of in the ordinary  course of
business,  (ii)  defects  in  title  set  forth  on  Schedule  4.7,  (iii)  such
imperfections  of  title,  easements,  rights  of way and  similar  matters  and
failures  of  title as  would  not,  individually  or in the  aggregate,  have a
Material  Adverse  Effect  on the  Company  or  materially  interfere  with  the
Company's use of such assets or properties, (iv) Liens for current Taxes not yet
due and  payable  or which  are being  contested  in good  faith by  appropriate
proceedings (and which have been sufficiently accrued or reserved against in the
Company  Balance  Sheet),  (v)  Liens  of  carriers,  warehousemen,   mechanics,
laborers,  materialmen,  landlords,  vendors,  workmen and operators  arising by

restrictions,    servitudes,   permits,   conditions,   covenants,   exceptions,

of the Company or rights to any of its assets,  and (vii) Liens  incurred in the
ordinary   course  of  business  in  connection   with  workers'   compensation,
unemployment  insurance and other social security legislation (other than ERISA)

other than assets and  properties in which the Company has leasehold  interests,
are free and clear of all Liens,  other than those (i) set forth in Schedule 4.7
and (ii) Liens, that, in the aggregate, do not and will not materially interfere
with the ability of the Company to conduct business as currently conducted or as
reasonably  expected to be conducted.  Except as set forth in Schedule 4.7, none
of the Company's properties,  assets or business are subject to any restrictions
with respect to the transferability thereof.

in the conduct of the normal operations of the Company),  ordinary wear and tear
excepted, and have been maintained consistent with prudent industry practice. No
other  assets or  properties  are needed to permit  the  Company to carry on its
business  as  conducted  during the  preceding  12 months and as  proposed to be

electrical,  sewerage,  or  heating,  ventilating  or air  conditioning  systems
(except  such  minor  defects  as do not  significantly  interfere  with the use
thereof in the conduct of the normal operations of the Company) and are suitable
and adequate for the purposes for which they are presently being used.

                  (f) The Company has  performed in all material  respects  each
material term, covenant and condition of each of the Material Contracts to which
it is a party or by which it is bound,  and, to the Knowledge of Sellers and the
Company,  no material  event of default on the part of any other  party  thereto
exists  under any of the  Material  Contracts.  The  Company  is  current on all

                  (g) To the Knowledge of Sellers and the Company,  no event has

the Company,  (i) the use of Intellectual  Property Rights by the Company in its
current operations does not infringe on the Intellectual  Property Rights of any

Material  Adverse  Effect on the  Company,  and (ii) no Person is, in any manner
that could have a Material  Adverse  Effect on the  Company,  infringing  on any

amendments, supplements or modifications thereto.

                  (b) The Company has  performed in all material  respects  each
material  term,  covenant  and  condition of each of the leases to which it is a
party or which is required to be  performed  by it at or before the date hereof,
and no  material  event  of  default  on the  part of the  Company  and,  to the
Knowledge  of Sellers and the Company,  on the part of any other party  thereto,
exists under any lease.

                  (c) Each of the leases is legal, valid,  binding,  enforceable
and in full force and effect, unimpaired by any acts or omissions of the Company
and  constitutes  the legal and binding  obligation of the Company in accordance
with its terms,  except  (i) such  enforcement  may be  subject  to  bankruptcy,



                                       12




insolvency,  reorganization,  moratorium  or  other  similar  laws  or  judicial
decisions now or hereafter in effect relating to creditors' rights generally and
(ii) the remedy of specific  performance and injunctive relief may be subject to
equitable  defenses  and to  the  discretion  of  the  court  before  which  any
proceeding therefor may be brought.

                  (d) To the  Knowledge of Sellers and the Company,  there is no

of business consistent with past practices, or (B) any guaranty,  endorsement or
other incurrence or assumption of liability,  whether directly,  contingently or
otherwise, by the Company for the obligations of any other Person, other than in

         4.16 No Litigation.  Except as disclosed on Schedule 4.16,  there is no
suit, action, proceeding or investigation presently pending or, to the Knowledge
of Sellers or the Company,  threatened against or affecting the Company that has
had or could  reasonably  be expected to have a Material  Adverse  Effect on the
Company or  prevent,  hinder or  materially  delay the ability of the Company to
consummate the  transactions  contemplated by this  Agreement,  nor is there any
judgment,  decree,  injunction,  rule or order  of any  Governmental  Entity  or
arbitrator  outstanding against the Company which has had, or which,  insofar as
reasonably can be foreseen, in the future could have, any such effect.

         4.17 Taxes.

         (a) Except as set forth in Schedule  4.17, the Company has timely filed
(taking into account any extensions) all Tax Returns  required to be filed by it
on or before the date of this  Agreement  and has timely paid or  deposited  all
Taxes and  estimated  Taxes  which are  required to be paid or  deposited  on or
before such date.  Each of the Tax Returns  filed by the Company is accurate and
complete  in all  material  respects  and has  been  completed  in all  material
respects in accordance with applicable laws,  regulations and rules. The Company
Balance Sheet  reflects an adequate  reserve for all Taxes for which the Company
may be liable for all taxable  periods  and  portions  thereof  through the date
thereof.  The Company has not waived any  statute of  limitations  in respect of
Taxes of the Company. No material deficiencies for any Taxes have been proposed,
asserted or assessed against the Company, no requests for waivers of the time to
assess  any such Taxes have been  granted or are  pending,  and there are no Tax




                                       15




Liens upon any assets of the Company  (except for liens for ad valorem Taxes not
yet  delinquent  and other Taxes not yet due and payable).  There are no current
examinations   of  any  Tax  Return  of  the  Company  being  conducted  by  any
Governmental Entity and there are no settlements of any prior examinations which
could  reasonably be expected to adversely  affect any taxable  period for which
the  statute of  limitations  has not run.  The  Company is not a party to a Tax
allocation  agreement,  Tax sharing  agreement,  Tax  indemnity  agreement,  Tax
partnership  agreement  or similar  agreement  or  arrangement.  The Company has
complied  in  all  material   respects  with  all  applicable  laws,  rules  and
regulations  relating  to the payment  and  withholding  of Taxes and has in all
respects  timely  withheld from  employee  wages and paid over such taxes to the
appropriate Governmental Entity. As used herein, "Tax" or "Taxes" shall mean all
taxes of any kind,  including those on or measured by or referred to as federal,
state,  local or foreign  income,  gross  receipts,  property,  sales,  use,  ad
valorem, franchise, profits, license, withholding, payroll, alternative or added
minimum, employment,  estimated, excise, transfer, severance, stamp, occupation,
premium,  value added,  or windfall  profits taxes,  customs,  duties or similar
fees, assessments or charges of any kind whatsoever,  together with any interest
and  any  penalties,  additions  to tax or  additional  amounts  imposed  by any
Governmental Entity. As used herein, "Tax Return" shall mean any return, report,
statement or information  required to be filed with any Governmental Entity with
respect to Taxes.

         (b) No amount  that could be paid  (whether  in cash or property or the
vesting of property) as a result of any of the transactions contemplated by this
Agreement  to  any  Person  who is  properly  characterized  as a  "disqualified
individual" (as such term is defined by the IRS in proposed Treasury  Regulation
section  1.280G-1)  under any  employment,  severance or termination  agreement,
other compensation arrangement or other Company Benefit Plan currently in effect
would be characterized as an "excess parachute payment" (as such term is defined
in section 280G(b)(1) of the Code).

         (c) The Company has not filed a consent under Code ss.341(f) concerning
collapsible corporations.  The Company is not and has never been a United States
real property holding  corporation  within the meaning of Code Section 897(c)(2)
during the applicable  period  specified in Code Section  897(c)(1)(A)(ii).  The

                  has ever  maintained,  had any  obligation to contribute to or

                  a result of the  transactions  contemplated by this Agreement,
                  except as disclosed in Schedule  4.23.  Except as disclosed in
                  Schedule  4.23,   the  Employer  does  not  provide   employee
                  benefits,     including,     without    limitation,     death,
                  post-retirement  medical or health  coverage  (whether  or not
                  insured) or  contribute  to or maintain any  employee  benefit
                  plan which provides for benefit coverage following termination
                  of employment except as is required by section 4980B(f) of the
                  Code or other similar applicable statute,  nor has it made any
                  representations,   agreements,  covenants  or  commitments  to
                  provide  that  coverage.  Any  employee  benefit  plan that is
                  disclosed  on  Schedule  4.23  has,  at all  times  since  its
                  inception, provided that the sponsor of the plan has the right
                  to  amend  and  terminate  the plan at any  time  without  the
                  consent of any party and no statements  have been made to plan
                  participants or their  dependents that would lead such persons
                  to  reasonably  conclude  the  plan  may  not  be  amended  or
                  terminated  without their consent.  All Company  Benefit Plans
                  that are group  health  plans have been  operated  in material
                  compliance with section 4980B(f) of the Code.

                  (iii) Except as set forth in Schedule  4.23,  the Company does
                  not  maintain  or  contribute  to, and has not  maintained  or
                  contributed to for the three-year period ending on the date of
                  this  Agreement,  a pension  plan that is  intended to qualify
                  under Section  401(a) of the Code or a pension plan  described
                  in  section  3(2) of ERISA.  Any  pension  plan  described  in
                  section 3(2) of ERISA previously maintained by the Company was
                  terminated in accordance with ERISA and the Code.

                  (iv) Except as set forth in Schedule  4.23,  the  transactions
                  contemplated by this Agreement, either alone or in conjunction
                  with another event (such as termination  of  employment)  will
                  not  accelerate the time of payment of any  contribution  to a
                  Company  Benefit  Plan,  accelerate  vesting  under a  Company
                  Benefit Plan, increase the amount of compensation  directly or
                  indirectly  due any Person from the Employer,  or increase the
                  cost of any Company Benefit Plan.

         (a) Sellers and the Company have no Knowledge  of, nor have any of them
been  informed  of, any existing or  anticipated  changes in the policies of the
customers,  suppliers or others with whom the Company  transacts  business  that
could  affect the  availability  of  materials,  or  supplies,  in any  material
respect, or of any legislation or regulation,  that will have a Material Adverse
Effect on the Company. As of the date of this Agreement, Sellers and the Company
have no  Knowledge  of any proposed or  contemplated  changes in the  employment
status of any members of management or key employees of the Company.

         (b) All  outstanding  commitments  of the Company  for the  delivery of
goods or the performance of services were made on an arms' length basis,  and to
the  Knowledge  of Sellers and the Company  there are no facts or  circumstances
that could have a Material Adverse Effect with respect thereto.

         (c) Schedule 4.29 contains a listing,  based on dollar volumes,  of the
top ten customers of and the top ten suppliers to the Company for the year ended
December 31, 2003.  No such  customer or supplier has advised the Company or any

any similar  corporate level tax imposed on the Company by any taxing authority.
To the  Knowledge  of Sellers  and the  Company,  the  Company  has no Tax item,

customer,  supplier,  government  employee or other Person who is or may be in a
position to help or hinder the business of the Company (or to assist the Company
in connection with any actual or proposed  transaction)  which (i) might subject
the  Company to any damage or penalty  in any civil,  criminal  or  governmental
litigation  or  proceeding,  (ii) if not  given in the  past,  might  have had a
Material Adverse Effect on the assets,  business or operations of the Company as

private or governmental litigation or proceeding.

misleading.

Disclosure of any fact in any provision of this  Agreement or in any Schedule to

any  proceeding  therefor  may be brought.  The  execution  and delivery of this
Agreement by Buyer do not, and the consummation of the transactions contemplated
hereby and  compliance  with the provisions  hereof will not,  conflict with, or
result in any violation of, or default (with or without notice or lapse of time,
or  both)  under,  or give  rise  to a right  of  termination,  cancellation  or
acceleration  of or "put" right with respect to any  obligation  or to loss of a
material  benefit  under,  or result in the  creation  of any Lien on any of the
properties or assets of Buyer or any of its subsidiaries under, any provision of

such conflicts,  violations,  defaults,  rights or Liens that individually or in
the  aggregate  would not have,  or would not  reasonably  be likely to have,  a
material  adverse  effect on Buyer and would  not,  or would not  reasonably  be
likely to,  materially  impair the ability of Buyer to perform  its  obligations
hereunder or prevent the  consummation of any of the  transactions  contemplated
hereby.  No  consent,  approval,  order or  authorization  of, or  registration,
declaration  or filing  with,  any  Governmental  Entity is  required by or with

to  herein  as the "SEC  Documents").  As of  their  respective  dates,  the SEC


                                       27


Documents  complied  in all  material  respects  with  the  requirements  of the
Securities  Act or the  Exchange  Act,  as the case may be,  and the  rules  and
regulations of the SEC promulgated  thereunder  applicable to the SEC Documents,
and none of the SEC Documents  contained any untrue statement of a material fact
or omitted to state a material fact  required to be stated  therein or necessary
in order to make the statements  therein,  in light of the  circumstances  under
which they were made, not misleading.  The consolidated  financial statements of
Buyer  included  in the SEC  Documents  comply  in all  material  respects  with
applicable  accounting  requirements  and the published rules and regulations of
the SEC with respect  thereto,  have been prepared in accordance  with generally
accepted accounting principles (except, in the case of unaudited statements,  as
permitted by Form 10-QSB of the SEC)  applied on a  consistent  basis during the
periods  involved  (except as may be indicated in the notes  thereto) and fairly
present  the  consolidated  financial  position  of Buyer  and its  consolidated
subsidiaries  as of the dates  thereof  and the  consolidated  results  of their
operations  and cash flows for the periods then ended  (subject,  in the case of
the interim financial statements,  to normal year-end audit adjustments).  There
is  no  liability  or  obligation  of  any  kind,  whether  accrued,   absolute,
determined,  determinable or otherwise, of Buyer or any subsidiary of Buyer that
is required by  generally  accepted  accounting  principles  to be  reflected or
reserved against or otherwise disclosed in the most recent financial  statements

Effect on Buyer. For purposes of this Agreement, "Buyer Balance Sheet" means the

10-QSB for the quarter ended June 30, 2004, and "Buyer Balance Sheet Date" means

operations or condition,  financial or otherwise, of Buyer and its subsidiaries,
taken as a whole.

         5.6 No Default.  Buyer is not in default,  breach or violation  (and no
event has  occurred  which,  with  notice  or the  lapse of time or both,  would
constitute a default or  violation)  of any term,  condition or provision of (i)
the Buyer Charter Documents; (ii) any note, bond, mortgage,  indenture, license,
agreement or other  instrument or obligation to which Buyer is now a party or by
which Buyer or any of its properties,  business or assets is bound; or (iii) any
order,  writ,  injunction,  decree,  statute,  rule or regulation  applicable to
Buyer,  except in the case of clauses (ii) and (iii) for defaults or  violations
which in the aggregate would not have a Material Adverse Effect on Buyer.

         5.7 No  Undisclosed  Liabilities.  Buyer  has  no  debt,  liability  or
obligation  of  any  kind,  whether  accrued,  absolute,  contingent,  inchoate,
determined,  determinable or otherwise (and there is no basis for any present or
future action, suit,  proceeding,  hearing,  investigation,  charge,  complaint,
claim or  demand  against  Buyer  giving  rise to any such  debt,  liability  or
obligation), except for (i) liabilities or obligations which, individually or in
the  aggregate  would  not  have  a  Material  Adverse  Effect  on  Buyer;  (ii)
liabilities or obligations  under this Agreement or incurred in connection  with
the transactions  contemplated  hereby;  or (iii) liabilities or obligations (A)
disclosed or provided for in the Buyer Balance Sheet or (B) disclosed in the SEC
Documents filed with the SEC prior to the date of this Agreement.



                                       28


         5.8 Compliance with Laws; Permits.  Buyer and its subsidiaries hold all
required,  necessary or applicable federal, state, provincial,  local or foreign
permits, licenses,  variances,  exemptions,  orders, franchises and approvals of
all Governmental Entities,  except where the failure to so hold would not have a
Material  Adverse  Effect  on  Buyer  (the  "Buyer  Permits").   Buyer  and  its
subsidiaries are in compliance with the terms of the Buyer Permits, except where
the  failure  to so comply  would not have a Material  Adverse  Effect on Buyer.
Neither Buyer nor any of its  subsidiaries has received notice of any revocation

assets or  operations,  except for  violations and failures to comply that could
not, individually or in the aggregate, reasonably be expected to have a material
adverse  effect on Buyer.  To the  Knowledge of Buyer,  there is no reason Buyer
would  not be  able  to  renew  without  material  expense  any of its  permits,
licenses,  or other  authorizations  required  to conduct and use any of Buyer's
current or planned  operations.  To the Knowledge of Buyer, no  investigation or
review  by  any  Governmental  Entity  with  respect  to  Buyer  or  any  of its
subsidiaries is threatened, other than those the outcome of which would not have
a Material Adverse Effect on Buyer.

investigation  presently  pending  or, to the  Knowledge  of  Buyer,  threatened
against  or  affecting  Buyer or any of its  subsidiaries  that has had or could
reasonably  be expected to have a Material  Adverse  Effect on Buyer or prevent,
hinder or materially  delay the ability of Buyer to consummate the  transactions
contemplated by this Agreement, nor is there any judgment,  decree,  injunction,
rule or order of any Governmental Entity or arbitrator outstanding against Buyer
or any of its subsidiaries which has had, or which, insofar as reasonably can be
foreseen, in the future could have, any such effect.

         5.11  Financing.  Buyer has or will have at  Closing  sufficient  funds
available on hand and under existing financing  facilities to pay to each holder

Consideration and to perform all of its other obligations under this Agreement.

         5.12 Taxes. Buyer has timely filed all federal,  state, local and other
Tax Returns required to be filed under applicable law, except as individually or
in the aggregate would not have a Material Adverse Effect on Buyer. All such Tax



                                       29


Returns were true and correct in all  material  respects  when filed.  Buyer has
paid all  required  Taxes  (including  any  additions  to Taxes,  penalties  and
interest related  thereto) due and payable on or before the date hereof,  except
as individually or in the aggregate would not have a Material  Adverse Effect on
Buyer.

contained in this Agreement and no written  statement of material fact furnished
or to be furnished by Buyer to Sellers  pursuant to or in  connection  with this
Agreement  contains or will contain any untrue  statement of a material  fact or
omits  or will  omit to state a  material  fact  necessary  in order to make the
statements herein or therein contained not misleading.

Disclosure of any fact in any provision of this  Agreement or in any Schedule to

purposes of all other provisions or Schedules.

conditions set forth in this Agreement,  except to the extent otherwise provided
in this Section 6.3, each of the parties agrees to use  commercially  reasonable



                                       34


efforts to take,  or cause to be taken,  all actions,  and to do, or cause to be
done,  and to assist and cooperate  with the other parties in doing,  all things
necessary,  proper or advisable to consummate  and make  effective,  in the most
expeditious  manner  practicable,  the  Purchase,  and  the  other  transactions
contemplated  by this  Agreement,  including  (i) the obtaining of all necessary
actions  or  nonactions,  waivers,  consents  and  approvals  from  Governmental
Entities and the making of all necessary  registrations  and filings  (including
filings with  Governmental  Entities,  if any) and the taking of all  reasonable
steps as may be necessary  to obtain an approval or waiver from,  or to avoid an
action or  proceeding  by, any  Governmental  Entity,  (ii) the obtaining of all
necessary consents, approvals or waivers from third parties, (iii) the defending
of any lawsuits or other legal proceedings,  whether judicial or administrative,
challenging this Agreement or the consummation of the transactions  contemplated
hereby,  including  seeking  to have any  stay or  temporary  restraining  order
entered by any court or other Governmental Entity vacated or reversed,  and (iv)
the execution and delivery of any additional instruments necessary to consummate
the transactions contemplated by this Agreement; provided, however, that neither
the Company nor Buyer  shall be under any  obligation  to take any action to the
extent that the Board of Directors  of such party shall  conclude in good faith,
after  consultation  with and based upon the written advice of their  respective
outside  legal  counsel  (which  advice  in each  case  need not  constitute  an
opinion),  that such  action  would  cause a breach of that Board of  Directors'
fiduciary  obligations  under  applicable  law. In  connection  with and without
limiting the foregoing,  each of the Company and Buyer and its respective  Board
of  Directors  shall  (i) take all  action  necessary  to  ensure  that no state
takeover  statute or similar  statute or regulation is or becomes  applicable to
the  Purchase,  (ii)  if any  state  takeover  statute  or  similar  statute  or
regulation  becomes  applicable  to the Purchase,  take all action  necessary to
ensure that the Purchase may be  consummated  as promptly as  practicable on the
terms  contemplated  by this  Agreement  and otherwise to minimize the effect of
such statute or regulation on the Purchase,  and (iii) cooperate with each other
in the  arrangements  for  refinancing  any  indebtedness  of, or obtaining  any
necessary new financing for, the Company and Buyer.

                  (b)  Notification.  The Company  shall give  prompt  notice to
Buyer,  and  Buyer  shall  give  prompt  notice  to  the  Company,  of  (i)  any
representation  or warranty  made by it  contained  in this  Agreement  becoming
untrue or inaccurate in any material respect or (ii) the failure by it to comply
with or satisfy in any material respect any covenant,  condition or agreement to
be complied  with or satisfied by it under this  Agreement;  provided,  however,
that no such  notification  shall affect the  representations  or  warranties or
covenants or agreements of the parties or the  conditions to the  obligations of
the parties hereunder.

         6.4 Fees and Expenses.  Except as provided in Section 9.2, all fees and
expenses  incurred in  connection  with the  Purchase,  this  Agreement  and the
transactions  contemplated hereby shall be paid by the party incurring such fees
or expenses, whether or not the Purchase is consummated.

         6.5 Public Announcements. The Company and Sellers, on the one hand, and
Buyer,  on the other hand, will consult with each other before issuing any press
release  or  otherwise  making  any  public   statements  with  respect  to  the



                                       35


transactions  contemplated  by this Agreement and shall not issue any such press
release or make any such public  statement  prior to such  consultation,  except
that each party may respond to questions from shareholders, respond to inquiries
from financial  analysts and media  representatives  in a manner consistent with
its past practice and make such  disclosure as may be required by applicable law
or by  obligations  pursuant to any listing  agreement  with the American  Stock
Exchange  without  prior  consultation  to the extent such  consultation  is not
reasonably  practicable.  The parties  agree that the initial  press  release or
releases to be issued in connection  with the execution of this Agreement  shall
be mutually agreed upon prior to the issuance thereof.

         6.6  Agreement  to  Defend.  In the  event  any  claim,  action,  suit,
investigation or other  proceeding by any  governmental  body or other person or
other legal  administrative  proceeding is commenced that questions the validity
or  legality  of the  transactions  contemplated  hereby  or  seeks  damages  in
connection  therewith,  the  parties  hereto  agree to  cooperate  and use their
reasonable efforts to defend against and respond thereto.

         6.7  American  Stock  Exchange.  Buyer  shall use its  reasonable  best
efforts  to list  on the  American  Stock  Exchange,  upon  official  notice  of
issuance,  the 609,756  shares of Buyer Common Stock to be issued in  connection
with the Purchase.

         6.8 Payment of Indebtedness.  Sellers will cause all indebtedness  owed
to the Company by any Seller or any  Affiliate  of any Seller to be paid in full
prior to Closing.

to  Buyer;  or  (ii)  Buyer  shall  not  have  provided   reasonable   assurance
satisfactory  to Sellers  that such breach or default will be cured on or before
the Closing Date;

                  (e) by Buyer,  if any of the  conditions  set forth in Section
7.1 or Section  7.2 shall not have been  fulfilled  by the  Closing  Date in any
material  respect or if satisfaction of such condition is or becomes  impossible
(unless the  nonfulfillment  results  primarily from Buyer itself  breaching any
representation  or  warranty or failing to perform  any  covenant  or  agreement
contained in this Agreement) and Buyer has not waived such condition on or prior
to the Closing;

                  (f) by Sellers,  if any of the conditions set forth in Section
7.1 or Section  7.3 shall not have been  fulfilled  by the  Closing  Date in any
material  respect or if satisfaction of such condition is or becomes  impossible



                                       39


(unless  the  nonfulfillment  results  primarily  from the  Company  or  Sellers
themselves  breaching any  representation  or warranty or failing to perform any
covenant or agreement  contained in this  Agreement) and Sellers have not waived
such condition on or prior to the Closing.

         8.2  Procedure  for  Termination,  Amendment,  Extension  or Waiver.  A
termination  of this  Agreement  pursuant to Section  8.1, an  amendment of this
Agreement  pursuant to Section 8.4 or an extension or waiver pursuant to Section
8.5  shall,  in order to be  effective,  require  in the case of the  Company or
Buyer,  action by its Board of Directors or the duly authorized  designee of its
Board of Directors.

         8.3  Effect  of  Termination.  In the  event  of  termination  of  this
Agreement by either  Sellers or Buyer as provided in Section 8.1, this Agreement
shall forthwith become void and have no effect, without any further liability or
obligation  on the part of  Sellers,  the  Company  or Buyer,  or any  director,
officer,  employee  or  shareholder  thereof,  other  than  the  confidentiality
provisions of Sections  6.2(b) and 6.2(c) and the  provisions of Sections  4.20,
5.8, 6.4, 8.3, 9.1 and Article 12; provided,  however, that any such termination
shall  not limit or  relieve  a party's  liability  or  obligation  for  damages
suffered by the other  party  hereto as a result of such  party's  breach of any
representation, warranty or covenant in this Agreement.

         8.4  Amendment.  This  Agreement  may  not  be  amended  except  by  an
instrument in writing signed by or on behalf of each of the parties.

         8.5 Extension; Waiver. At any time on or prior to the Closing Date, the
parties may (a) extend the time for the performance of any of the obligations or
the  other  acts  of the  other  parties,  (b)  waive  any  inaccuracies  in the
representations  and warranties  contained  herein or in any document  delivered
pursuant  hereto,  or  (c)  waive  compliance  with  any of  the  agreements  or
conditions  contained  herein.  Any agreement on the part of a party to any such
extension or waiver shall be valid only if set forth in an instrument in writing
signed by or on behalf of such party. No waiver of any of the provisions of this
Agreement shall be deemed or shall constitute a waiver of any other provision or
breach of this Agreement,  whether or not similar,  unless  otherwise  expressly
provided. The failure of any party to this Agreement to assert any of his or its
rights under this  Agreement or otherwise  shall not constitute a waiver of such
rights.


                                    ARTICLE 9
                    SPECIAL PROVISIONS AS TO CERTAIN MATTERS

         9.1 No  Negotiation.  Provided that Buyer is not in default  hereunder,
from the date of this  Agreement  until the  earlier  date of the Closing or the
termination  of this  Agreement  pursuant to Section 8.1,  Sellers will not, and
will  cause  the  Company  and  its  officers,  directors,   employees,  agents,
Affiliates and other  representatives  not to, directly or indirectly,  solicit,



                                       40


initiate,  or encourage  any inquiries or proposals  from,  discuss or negotiate
with,  provide any  non-public  information  to, or  consider  the merits of any
unsolicited  inquiries or proposals from, any Person (other than Buyer) relating
to any  transaction  involving the sale of the business or all or  substantially
all of the assets of the Company, or any of the capital stock of the Company, or
any  merger,   consolidation,   business  combination,  or  similar  transaction
involving the Company.

         9.2 Audited Financial Statements.  Promptly after the execution of this
Agreement  by all  parties  hereto,  the  Company  shall  engage an  independent
accounting  firm meeting the  requirements  of Article 2 of Regulation S-X under
the Securities Act and who shall otherwise be reasonably  satisfactory to Buyer.
The  Company  shall  engage  such  independent  accountants  for the  purpose of
authorizing  and retaining  such firm to conduct,  in accordance  with generally
accepted  auditing  standards,  an audit of the Company's  financial  statements
which shall be prepared in accordance with and satisfy the  requirements of Item
2.01 of Form 8-K and Regulation S-X as now or hereafter in effect.  All fees and
expenses  attributable to the audit of the Company's financial  statements shall
be paid by  Buyer;  provided,  however,  Sellers  will pay and  reimburse  Buyer
one-half of such fees and expenses if there is no Closing  under this  Agreement
as a result of a Seller's or the Company's  breach of Section 9.1 or as a result
of any other material breach of this Agreement by Sellers or the Company.


                                   ARTICLE 10
                                 INDEMNIFICATION

         10.1  Indemnification  of Buyer.  Subject to Section  10.1(d),  Sellers
agree, jointly and severally, to defend,  indemnify and hold harmless Buyer, the
Company,  and their  respective  successors and assigns  (individually  a "Buyer
Indemnitee," and collectively the "Buyer  Indemnitees")  from,  against,  and in
respect of the following:

                  (a) any and all losses,  damages,  deficiencies or liabilities
caused by,  resulting or arising from, or otherwise  relating to: (i) any breach
of the  representations  and  warranties of Sellers or the Company  contained in
this Agreement or in any instrument, certificate or affidavit delivered by or on
behalf  of  Sellers  or the  Company  at the  Closing  in  accordance  with this
Agreement;  or (ii) any  failure by either  Sellers or the Company to perform or
otherwise  fulfill  or  comply  with  (X) if  this  Agreement  shall  have  been
terminated,  Section  6.3,  Section  9.1 or  any  other  covenant,  undertaking,
agreement or obligation  to be performed,  fulfilled or complied with by Sellers
or the Company prior to or in connection  with the Closing or (Y) if the Closing
shall occur,  any  covenant,  undertaking  or other  agreement or  obligation of
Sellers under this  Agreement to be performed,  fulfilled or otherwise  complied
with by Sellers after the Closing; and

                  (b)  any  and  all  actions,   suits,   proceedings,   claims,
liabilities,  demands,  assessments,  judgments,  interest, penalties, costs and
expenses,   including   reasonable   attorneys'  fees,  incurred  by  the  Buyer
Indemnitees in connection with investigating, defending, settling or prosecuting
any action, suit,  proceeding or claim against Buyer hereunder,  incident to any
of the items  referred to in Section  10.1(a);  provided,  that,  if any action,
suit,  proceeding,  claim,  liability,  demand or  assessment  shall be asserted
against any Buyer Indemnitee in respect of which such Buyer Indemnitee  proposes



                                       41


to demand  indemnification,  such Buyer  Indemnitee shall notify Sellers thereof
within a  reasonable  period of time after  assertion  thereof,  and such notice
shall  include  copies of all suit,  service and claim  documents  and all other
relevant  documents in the possession of the Buyer Indemnitee and an explanation
of the Buyer Indemnitee's  contentions and defenses with as much specificity and
particularity as the circumstances permit;  provided,  further, that the failure
of the Buyer Indemnitee to give such notice or provide such documentation  shall
not relieve  Sellers of their  obligations  under this Section  10.1, if Sellers
shall not have been prejudiced  thereby (and then solely to the extent thereof).
Subject  to rights of or duties to any  insurer  or other  third  Person  having
liability  therefor,  Sellers  shall  have the right  within ten (10) days after
receipt  of such  notice  to assume  in  writing  the  control  of the  defense,
compromise or settlement of any such action, suit, proceeding, claim, liability,
demand, or assessment,  including, at their own expense,  employment of counsel;
provided further,  however, that, if Sellers shall have exercised their right to
assume such control, the Buyer Indemnitee may, in its sole discretion and at its
sole expense, employ counsel to represent it (in addition to counsel employed by
Sellers) in any such matter, and in such event counsel selected by Sellers shall
be required  to  cooperate  with such  counsel of the Buyer  Indemnitee  in such
defense,  compromise  or  settlement  for the purpose of  informing  and sharing
information with such Buyer Indemnitee. So long as Sellers are defending in good
faith any such claim or demand  asserted  by a third  Person  against  the Buyer
Indemnitee,  the Buyer  Indemnitee  shall not settle or compromise such claim or
demand.  If Sellers have  assumed the defense of any such claim or demand,  then
they shall not  consent to the entry of  judgment  or enter into any  settlement
without the prior written consent of the Buyer  Indemnitee,  which consent shall
not be  unreasonably  withheld.  The Buyer  Indemnitee  shall make  available to
Sellers  or  their  agents  all  records  and  other   materials  in  the  Buyer
Indemnitee's  possession reasonably required by them for their use in contesting
any third party claim or demand.

                  (c) Upon notice to Sellers specifying in reasonable detail the
basis for such set-off, any indemnification obligation of Sellers hereunder may,
at the option of Buyer, be set-off and applied  against the outstanding  balance
of the Promissory Notes due to the affected Sellers, in the amount of such claim
for  indemnification,  as  if  such  indemnification  claim  had  resulted  in a
reduction of the Purchase  Consideration  and therefore of the principal balance
of the  Promissory  Notes as of the Closing Date.  The exercise of such right of
set-off by Buyer in good  faith,  whether  or not  ultimately  determined  to be
justified,  will not constitute an event of default under the Promissory  Notes.
Neither the  exercise of nor the failure to exercise  such right of set-off will
constitute  an  election  of  remedies  or  limit  Buyer  in any  manner  in the
enforcement of any other remedies that may be available to it.

                  (d) Breaches of  representations  and warranties  contained in
Sections  4.4,  4.5(b) and 4.6 (as related  solely to the Sellers and not to the
Company)  shall be subject  only to several  indemnification  by the  respective
Sellers who shall have made and breached such representations and warranties.

         10.2 Indemnification of Sellers. Buyer agrees to defend,  indemnify and
hold harmless Sellers and their respective  successors and assigns (individually
a "Seller Indemnitee," and collectively the "Seller  Indemnitees") from, against
and in respect of the following:



                                       42


                  (a) any and all losses,  damages,  deficiencies or liabilities
caused by, resulting or arising from or otherwise  relating to (i) any breach of
the  representations  and warranties of Buyer  contained in this Agreement or in
any instrument,  certificate or affidavit  delivered by or on behalf of Buyer at
the  Closing in  accordance  with this  Agreement;  (ii) any failure by Buyer to
perform or otherwise  fulfill or comply with: (X) if this  Agreement  shall have
been terminated,  Section 6.3 or any other covenant,  undertaking,  agreement or
obligation to be  performed,  fulfilled or complied with by Buyer prior to or in
connection  with the Closing;  or (Y) if the Closing shall occur,  any covenant,
undertaking  or  other  agreement  or  obligation  hereunder  to  be  performed,
fulfilled  or  otherwise  complied  with by Buyer after the Closing or (iii) any
obligation  or liability  with respect to the  operation of the Company by Buyer
after the Closing;

                  (b)  any  and  all  actions,   suits,   proceedings,   claims,
liabilities,  demands,  assessments,  judgments,  interest, penalties, costs and
expenses,   including  reasonable   attorneys'  fees,  incurred  by  the  Seller
Indemnities in connection with investigating, defending, settling or prosecuting
any action, suit,  proceeding or claim against any Seller Indemnitee  hereunder,
incident to any of the items referred to in Section 10.2(a);  provided, that, if
any action, suit, proceeding,  claim,  liability,  demand or assessment shall be
asserted  against  any  Seller  Indemnitee  in  respect  of  which  such  Seller
Indemnitee  proposes to demand  indemnification,  such Seller  Indemnitee  shall
notify Buyer thereof within a reasonable period of time after assertion thereof,
and such notice shall include copies of all suit,  service and claim  documents,
all other relevant  documents in the possession of the Seller  Indemnitee and an
explanation  of the Seller  Indemnitee's  contentions  and defenses with as much
specificity and particularity as the circumstances  permit;  provided,  further,
that the failure of the Seller  Indemnitee  to give such notice or provide  such
documentation shall not relieve Buyer of its obligations under this Section 10.2
if Buyer shall not have been  prejudiced  thereby (and then solely to the extent
thereof).  Subject to rights of or duties to any insurer or other  third  Person
having liability therefor, Buyer shall have the right within ten (10) days after
receipt of such  notice to assume  the  control of the  defense,  compromise  or
settlement of any such action, suit, proceeding,  claim,  liability,  demand, or
assessment,  including,  at its own expense,  employment  of counsel;  provided,
that, if Buyer shall have exercised its right to assume such control, the Seller
Indemnitee may, in its sole  discretion and at its sole expense,  employ counsel
to represent  it (in addition to counsel  employed by Buyer) in any such matter,
and in such event counsel  selected by Buyer shall be required to cooperate with
such counsel of the Seller Indemnitee in such defense,  compromise or settlement
for  the  purpose  of  informing  and  sharing   information  with  such  Seller
Indemnitee.  So long as Buyer is  defending  in good  faith  any such  claims or
demands  asserted by a third Person  against the Seller  Indemnitee,  the Seller
Indemnitee  shall not settle or  compromise  such claim or demand.  If Buyer has
assumed  the  defense of any such claim or demand,  then it shall not consent to



                                       43


the entry of judgment  or enter into any  settlement  without the prior  written
consent  of the  Seller  Indemnitee  (which  consent  shall not be  unreasonably
withheld). The Seller Indemnitee shall make available to Buyer or its agents all
records and other  materials in the Seller  Indemnitee's  possession  reasonably
required by it for its use in contesting any third party claim or demand.

         10.3 Remedies; Specific Performance.

                  (a) The  indemnification  provisions of this Article 10 are in
addition to, and not in lieu or in  derogation  of, any other rights or remedies
any  party may have at law or in  equity  for a breach  of any  representations,
warranties or covenants contained in this Agreement.

                  (b) Each of the  parties to this  Agreement  acknowledges  and
agrees  that  Buyer  would be damaged  irreparably  if any of the  covenants  of
Sellers under this Agreement are not performed in accordance with their specific
terms or otherwise are breached.  Accordingly, each of the parties hereto agrees
that Buyer shall be entitled to an injunction or injunctions to prevent breaches
of the  covenants  set  forth  in  this  Agreement  by  Sellers  and to  enforce
specifically this Agreement and the terms and provisions hereof in any competent
court having  jurisdiction over the parties,  in addition to any other remedy to
which it may be entitled, at law or in equity.

                  (c) No Buyer Indemnitee or Seller Indemnitee shall be entitled
to seek indemnification  under this Article 10 with respect to any loss, damage,
deficiency  or  liability   ("Claim"),   unless  such  Indemnitee  notifies  the
indemnifying  party of such Claim in writing  within 24 months after the Closing
Date.

                  (d)  If the  total  amount  of  all  Claims  which  the  Buyer
Indemnitees  collectively  have the right to assert against Sellers  (determined
without regard to any materiality  qualification contained in any representation
or warranty  giving rise to such Claim) under this  Article 10 ("Buyer  Claims")
does not exceed an amount  equal to one  percent of the  Purchase  Consideration
(the "Basket"), then Sellers shall have no obligation under this Article 10 with
respect to any such Claim.  If the total amount of all Buyer Claims  exceeds the
Basket, then Sellers'  obligations under this Article 10 shall be limited to the
amount by which the aggregate amount of all Buyer Claims exceeds the Basket.

                  (e) Except as otherwise  provided in this Section 10.3(e),  in
the absence of fraud or willful  misconduct  on the part of any of Sellers,  the
total  amount of Sellers'  obligations  with  respect to Buyer  Claims  shall be
limited to an  aggregate  maximum  amount  equal to 10  percent of the  Purchase
Consideration.  The total  amount of any  Seller's  obligations  with respect to
Buyer Claims shall be limited to an aggregate maximum amount equal to 10 percent
of the Purchase  Consideration received by such Seller. The liability of Sellers
with  respect to Buyer Claims  shall be pro rata among  Sellers,  based on their
respective  shares of the Purchase  Consideration.  Notwithstanding  anything in
this Section 10.3(e) or elsewhere in this Agreement to the contrary, in no event
shall Sellers' obligations be limited in any manner with respect to Buyer Claims
arising out of or attributable to a breach of Section 4.4.

                  (f)  Notwithstanding  any  provision of this  Agreement to the
contrary,  Buyer's  and  Sellers'  sole  remedy  for  any  breach  of any of the



                                       44


provisions  of  Article 4  (excluding,  however,  Section  4.4) or 5 shall be to
exercise  their  rights  under this  Article  10,  which shall be subject to the
procedures and limitations set forth in this Article 10, excluding however,  any
cause of action for specific performance.

         10.4 Survival.  Notwithstanding  any other provision to the contrary in
this Agreement,  this Article 10 shall survive termination of this Agreement for
the period set forth in Section 10.3(c).


                                    ARTICLE 11
                                   TAX MATTERS

         The following  provisions shall govern the allocation of responsibility
as between  Buyer,  on the one hand,  and Sellers and the Company,  on the other
hand, for certain Tax matters following the Closing Date:

         11.1 Tax  Periods  Ending on or Before the  Closing  Date.  The Company
shall  prepare  or cause to be  prepared  and file or cause to be filed  all Tax
Returns,  reports and other  informational  statements and documentation for the
Company  for all  periods  ending  on or prior to the  Closing  Date,  which are
required to be filed on, before or after the Closing Date.  Sellers shall permit
Buyer (with  respect to Tax  Returns  filed after the date hereof and before the
Closing Date) or Buyer and the Company shall permit Sellers (with respect to Tax
Returns  filed  after the  Closing  Date) to review and comment on each such Tax
Return  described in the preceding  sentence prior to filing.  The Company shall
pay or cause to be paid any Taxes owed by the Company for all periods  ending on
or before the Closing  Date,  whether or not such Taxes are shown as owed on the
appropriate Tax Returns.

         11.2 Tax Periods  Beginning  Before and Ending After the Closing  Date.
Buyer shall  prepare or cause to be  prepared  and file or cause to be filed any
Tax Returns of the Company for Tax periods  which begin  before the Closing Date
and end after the Closing Date. Buyer shall permit Sellers to review and comment
on each such Tax Return.

         11.3 Cooperation on Tax Matters.

                  (a) Buyer, the Company and Sellers shall reasonably cooperate,
as and to the extent reasonably requested by the other party, in connection with
the filing of Tax Returns pursuant to this Article 11 and any audit,  litigation
or other  proceeding  with respect to Taxes for which the other party shall have



                                       45


liability  therefor under this  Agreement.  Such  cooperation  shall include the
retention  and (upon the other  party's  request)  the  provision of records and
information which are reasonably relevant to any such audit, litigation or other
proceeding and making employees  reasonably  available on a mutually  convenient
basis to provide additional information and explanation of any material provided
hereunder.  The Company  shall  retain all books and records with respect to Tax
matters pertinent to the Company relating to any Tax period beginning before the
Closing Date until the  expiration  of the statute of  limitations  (and, to the
extent notified by Buyer or Sellers,  any extensions  thereof) of the respective
Tax periods,  and to abide by all record retention  agreements entered into with
any taxing authority.

                  (b)  Buyer,  the  Company  and  Sellers  further  agree,  upon
request, to use their commercially  reasonable efforts to obtain any certificate
or other  document  from any  Governmental  Entity or any other Person as may be
necessary  to  mitigate,  reduce  or  eliminate  any Tax that  could be  imposed
(including with respect to the transactions contemplated hereby).

                  (c)  Buyer,  the  Company  and  Sellers  further  agree,  upon
request,  to provide the other party with all information  that either party may
be required  to report  pursuant  to Section  6043 of the Code and all  Treasury
Department Regulations promulgated thereunder.

         11.4 Tax  Sharing  Agreements.  Sellers  shall  cause  the  Company  to
terminate  as of the Closing all tax sharing  agreements  or similar  agreements
with  respect  to or  involving  the  Company,  and as of the  Closing  Date and
thereafter,  the Company shall not be bound thereby or have any liability  under
any such agreement or arrangement.

         11.5 Certain  Taxes.  All transfer,  documentary,  sales,  use,  stamp,
registration  and other such Taxes  incurred in connection  with this  Agreement
shall be paid by Sellers when due, and Sellers will, at their own expense,  file
all  necessary  Tax returns  and other  documentation  with  respect to all such
transfer, documentary, sales, use, stamp, registration and other Taxes and fees,
and, if required by applicable law, Buyer will join in the execution of any such
Tax Returns and other documentation.

         11.6     Section 338(h)(10) Election.

         (a)  Following  the  Closing,  and if  requested  by  Buyer in its sole
discretion,  Sellers  will  timely  file with Buyer an  election  under  Section
338(h)(10) of the Code,  electing to treat the acquisition of the Company Shares
as an asset  purchase.  Sellers  agree  to  execute  and  deliver  to Buyer  any
documents required to be executed by Sellers in connection with such election.

         (b) In accordance with the provisions of Section 2.2(d) Buyer shall pay
to Sellers an amount (the "338  Adjustment")  which shall be equal to the sum of
(i) the  difference  between the total federal and state income taxes payable by
Sellers and the  Company as a result of the sale of the  Company  Shares and the
amount of such federal and state income taxes that Sellers and the Company would
have paid but for the Section 338(h)(10)  election made pursuant to the terms of
this Agreement, and (ii) a gross up amount equal to the federal and state income
taxes payable by Sellers as a result of their receipt of the 338 Adjustment. The
amount of federal  and state  taxes that are  actually  paid and that would have
been paid shall be calculated using the highest applicable marginal rates.

         (c) Sellers  shall,  at their  expense,  prepare and file the final "S"
corporation, short period Tax Return for the Company for the period from January
1, 2004,  to the Closing Date (the "Final  Return").  Sellers  shall  provide to



                                       46


Buyer a draft of the Final  Return along with the  Sellers'  calculation  of the
amount of the 338 Adjustment and supporting  document for such calculations,  no
later than 120 days following Closing.

         (d) The total Purchase  Consideration  paid for the Company Shares,  as
described  in Section  2.1,  shall for  purposes of the  338(h)(10)  election be
allocated among the assets of the Company including  contracts in progress based
on a fair market value  balance sheet of the Company as of the Closing Date with
any excess purchase price being allocated to the Company's  goodwill.  Within 90
days after the Closing Date,  Buyer will provide Sellers with a statement of the
allocation  of the  Purchase  Consideration.  Sellers and Buyer will  jointly be
responsible for preparing and filing all documents and materials,  including the
statement  pursuant to Section  1060 of the Code (the  "Allocation  Statement"),
necessary in  connection  with the making of the  338(h)(10)  election,  and any
similar  elections  under  state or local law.  Sellers  and Buyer will file all
reports and returns filed with any Governmental  Entity (including the IRS) in a
manner  consistent  with the  338(h)(10)  election,  the valuation of the assets
determined as provided above in the Allocation Statement.

         (e) If the actual federal,  state and local taxes payable by Sellers as
a result of the sale of the  Company  Shares  are  ultimately  determined  to be
greater  than the  amount  of the 338  Adjustment  then  Buyer  shall pay to the
Sellers the sum of (i) the amount of such difference,  and (ii) the gross amount
equal to all federal,  state,  and local taxes payable by Sellers as a result of
their  receipt of the amount as  calculated  under  clauses (i) and (ii) of this
subparagraph  (e). If the Sellers' actual taxes are ultimately  determined to be
less than the amount of the 338 Adjustment,  then Sellers shall pay to Buyer the
excess of the 338 Adjustment  previously paid to Sellers over the amount the 338
Adjustment would have been if the Sellers' taxes had been as finally determined.
Sellers agree to furnish Buyer with a calculation  of the revised 338 Adjustment
amount and supporting evidence of any final determination of the Sellers' actual
taxes within thirty (30) days after same has occurred, and payment shall be made
under this paragraph  within thirty (30) days after the information is furnished
to Buyer.


                                   ARTICLE 12

(the "Maker"), a Colorado corporation with principal offices at 2911 S. County Road 1260, Midland, Texas 79706, promises to pay to the order of ___________________, an individual residing at _______________________________ ("Payee"), at his address in the City of Tulsa, Tulsa County, Oklahoma, in lawful money of the United States of America, the sum of _____________________________ ($__________), together with interest on the outstanding principal balance hereof (calculated on the basis of actual days elapsed in a year consisting of 365 days) from date until maturity at a rate equal to four percent (4.00%) per annum. Principal on this Promissory Note (this "Note") shall be due and payable in three equal annual installments as follows: (1) $____________ shall be due and payable on ____________ 15, 2005; $__________ shall be due and payable on __________ 15, 2006; and (2) one final installment of all remaining unpaid principal shall be due and payable in full on _______ 15, 2007. Accrued and unpaid interest on the unpaid principal balance of this Note shall be due and payable on the same dates as, but in addition to, the installments of principal. Subject to the prior written consent of Payee, Maker may, but shall not be obligated to, make principal payments on this Note: (1) in shares (only whole shares) of Buyer Common Stock valued at the Cash Equivalent Amount Per Share for the purposes of determining the number of shares of Buyer Common Stock to be issued; or (2) by combination of cash and such shares. "Cash Equivalent Amount Per Share" means the average of the daily closing prices of Buyer Common Stock on the American Stock Exchange for the twenty consecutive trading days commencing thirty trading days before the due date of any principal payment. All past due principal on this Note shall bear interest at the rate of ten percent (10%) per annum until such sums have been paid; provided, however, that in no event shall interest on this Note ever be charged or paid at a rate greater than the maximum nonusurious rate permitted by applicable federal or Texas law from time to time in effect, whichever shall permit the higher lawful rate (the "Highest Lawful Rate"). Interest shall be computed on the basis of the actual number of days elapsed in a year composed of 365 or 366 days, as the case may be. At all such times, if any, as Chapter One ("Chapter One") of the Texas Credit Code shall establish the Highest Lawful Rate, the Highest Lawful Rate shall be the "indicated rate ceiling" (as defined in Chapter One ) from time to time in effect. If, for any reason whatever, the interest paid or received on this note shall exceed the Highest Lawful Rate, the owner or holder of this note shall refund to the payor or, at the option of such owner or holder, credit against the principal of this note such portion of said interest as shall be necessary to cause the interest actually paid and retained on this note to equal the Highest Lawful Rate. All sums paid or agreed to be paid to the holder or holders hereof for the use, forbearance or detention of the indebtedness evidenced hereby shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full term of this note. Maker may prepay this Note in whole or in part at any time and from time to time without the payment of any premium or fee. All prepayments hereon shall be applied to the installments of principal in inverse order of their maturities. This Note is one of the Promissory Notes referred to in the Stock Purchase Agreement, dated of even date herewith, by and among Screw Compression Systems, Inc., a Texas corporation, __________, __________, Payee and Maker (the "Agreement"), and is subject to the terms and conditions of such Agreement. Reference is made to the Agreement for a statement of the rights, remedies, powers, privileges, benefits, duties and obligations of Maker and Payee under the Agreement. Capitalized terms used herein which are defined in the Agreement shall have such defined meanings unless otherwise defined herein. Payment of this Note is secured by that certain Irrevocable Standby Letter of Credit, dated _________, 2004, in the face amount of _________________________ Dollars, issued by Western National Bank, Midland, Texas, naming Payee as beneficiary. Reference is made to the Letter of Credit for a statement of the nature and extent of the security and the rights and obligations of the Maker and Payee thereunder. Time is of the essence of this Note. If Maker fails to pay when due any installment of principal and such failure to pay continues for a period of five days after Maker's receipt of written notice from Payee, the holder of this Note may, at such holder's option, declare the entirety of the indebtedness evidenced hereby immediately due and payable and exercise any other available remedies, and failure to exercise any remedy shall not constitute a waiver at any other time. If this Note or any installment or part hereof is not paid when due, whether at maturity or by acceleration, or if it is collected through a bankruptcy, probate or other court proceeding, whether before or after maturity, the undersigned agrees to pay all costs and expenses of collection, including, but not limited to, reasonable attorneys' fees, incurred by the holder hereof. Maker waives notice (including, but not limited to, notice of protest, notice of dishonor, notice of intent to accelerate and notice of acceleration), demand, presentment for payment, protest, diligence in collecting or bringing suit and the filing of suit for the purpose of fixing liability.

Employee agrees that during the Employment Term, Employee will not: (i) engage or participate in any manner, whether directly or indirectly through any family member or as an employee, employer, consultant, agent, principal, partner, more than one percent shareholder, officer, director, licensor, lendor, lessor or in any other individual or representative capacity, in any business activity that relates to (A) the business of manufacturing, fabricating, selling, leasing and maintaining of natural gas compressors, (B) the design and manufacture of natural gas flare systems, components and ignition systems, (C) installing and servicing flare stacks and related ignition and control devices or (D) in any other business or activity related to the natural gas compressor industry that is in competition in any manner whatsoever with the business of any of the Related Parties within a 700 mile radius of Tulsa, Oklahoma; provided that, this shall not preclude Employee from: (A) making investments in securities of oil and gas companies and natural gas compressor companies which are registered on a national stock exchange, if the aggregate amount owned by Employee and all family members and affiliates does not exceed one percent of such company's outstanding securities; or (B) maintaining his personal investments (whether in his own name or in the name of any family members) (including, without limitation, his investments in the following controlled affiliates of Employee: ________________________), if such personal investments and controlled affiliates do not engage in any business activity that relates to the business of manufacturing, fabricating, selling, leasing and maintaining of natural gas compressors, or the design and manufacture of natural gas flare systems, components and ignition systems, or the installation and servicing of flare stacks and related ignition and control devices; or (ii) solicit, entice, persuade or induce, directly or indirectly, any employee (or person who within the preceding ninety (90) days was an employee) of any of the Related Parties or any other person who is under contract with or rendering services to any of the Related Parties, to terminate his or her employment by, or contractual relationship with, such person or to refrain from extending or renewing the same (upon the same or new terms) or to refrain from rendering services to or for such person or to become employed by or to enter into contractual relations with any Persons other than such person or to enter into a relationship with a competitor of any of the Related Parties. (e) For purposes of this Agreement, the term "Noncompetition Period" means the period commencing on the date Employee ceases to be employed hereunder and ending on the second anniversary of such date. (f) The invalidity or non-enforceability of this Section 6 in any respect shall not affect the validity or enforceability of this Section 6 in any other respect or of any other provision of this Agreement. If any provision of this Section 6 shall be held invalid or unenforceable by a court of competent jurisdiction by reason of the geographic or business scope or the duration thereof, such invalidity or unenforceability shall attach only to the scope or duration of such provision and shall not affect or render invalid or unenforceable any other provision of this Agreement, and, to the fullest extent permitted by law, this Agreement shall be construed as if the geographic or business scope or the duration of such provision had been more narrowly drafted so as not to be invalid or unenforceable.

(h) The provisions of this Section 6 shall survive termination of this Agreement. (i) The representations and covenants contained in this Section 6 on the part of the Employee will be construed as ancillary to and independent of any other provision of this Agreement, and the existence of any claim or cause of action of the Employee against the Company or any of the other Related Parties or any officer, director or shareholder of the Company or any of the other Related Parties, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Company of the covenants of the Employee contained in this Section 6. In addition, the provisions of this Section 6 shall continue to be binding upon the Employee in accordance with their terms, notwithstanding the termination of the Employee's employment hereunder for any reason. (j) The parties to this Agreement agree that the limitations contained in this Section 6 with respect to time, geographical area and scope of activity are reasonable. However, if any court shall determine that the time, geographical area or scope of activity of any restriction contained in this Section 6 is unenforceable, it is the intention of the parties that such restrictive covenant set forth herein shall not thereby be terminated but shall be deemed amended to the extent required to render it valid and enforceable. 7. Business Records. The Employee agrees to promptly deliver to the Company, upon termination of his employment hereunder, or at any other time when the Company so requests, all of the Related Parties' Business Records (and all copies thereof and therefrom). The Employee confirms that all of the Related Parties' Business Records (and all copies thereof and therefrom) constitute the exclusive property of the Company and the other Related Parties. The obligation of confidentiality set forth in Section 6 shall continue notwithstanding the Employee's delivery of any such documents to the Company. Notwithstanding the foregoing provisions of this Section 7 or any other provision of this Agreement, the Employee shall be entitled to retain any written materials received by the Employee in his capacity as a shareholder of the Company. The provisions of this Section 7 shall continue in effect notwithstanding termination of the Employee's employment hereunder for any reason. 8. Divisibility of Agreement.

By:______________________________ Wallace C. Sparkman, President EMPLOYEE: _________________________________ EXHIBIT F Stockholders' Agreement ----------------------- Natural Gas Services Group, Inc. 2911 South County Road 1260 Midland, Texas 79706 Gentlemen: Natural Gas Services Group, Inc. ("NGSG "), a Colorado corporation, is issuing an aggregate of 609,756 shares of its common stock, par value $.01 per share (the "Restricted Securities"), to Paul Hensley, Jim Hazlett and Tony Vohjesus (collectively, the "Sellers" and each individually, a "Seller") as partial consideration for NGSG's purchase (the "Purchase") of all of the issued and outstanding shares of capital stock of Screw Compression Systems, Inc., a Texas corporation, from Sellers pursuant to the Stock Purchase Agreement, dated as of , 2004 (the "Purchase Agreement"). The undersigned understands that the issuance is being made pursuant to exemptions from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act"), and pursuant to exemptions from the registration and other requirements of applicable state securities laws. In order to induce NGSG to consummate the Purchase, Sellers have executed and delivered this Stockholders' Agreement (this "Agreement") to NGSG. 1. Representations, Warranties and Covenants of Each Seller. Each Seller, severally and not jointly, hereby represents, warrants and covenants to NGSG as follows: a. Such Seller is acquiring the Restricted Securities for his own account for investment purposes only, and not with a view to, or for resale in connection with, any distribution other than in compliance with the registration requirements under the Securities Act or the securities laws of any state or pursuant to an exemption therefrom. b. Such Seller understands that (A) the Restricted Securities (1) have not been registered under the Securities Act or any state securities laws, (2) will be issued in reliance upon an exemption from the registration and prospectus delivery requirements of the Securities Act and state securities laws for an offer and sale of securities not involving a public offering which relate to private purchases and (3) may not be sold, transferred or otherwise disposed of without satisfaction of certain conditions, including registration under, or the availability of an exemption from registration under, the Securities Act and applicable state securities laws, and (B) such Seller must therefore bear the economic risk of such investment indefinitely unless a subsequent disposition thereof is registered under the Securities Act and applicable state securities laws or is exempt therefrom. Such Seller further understands that such exemptions depend upon, among other things, the nature of the investment intent of the undersigned expressed herein. c. Such Seller has been furnished by NGSG all information (or provided access to all information) regarding the business and financial condition of NGSG, the attributes of the Restricted Securities and the merits and risks of an investment in the Restricted Securities which such Seller has requested to evaluate an investment in the Restricted Securities. Specifically, the undersigned acknowledges that such Seller has had an opportunity to review NGSG 's Annual Report on Form 10-KSB for the year ended December 31, 2003 and Quarterly Reports on Form 10-QSB for the fiscal quarters ended March 31, 2004 and June 30, 2004 and the other SEC Documents (as defined in the Purchase Agreement). d. Such Seller is an "accredited investor" as defined in Rule 501 of Regulation D promulgated under the Securities Act, and he, or those persons retained by him, has knowledge, skill and experience in financial, business and investment matters relating to an investment of the same nature as the Restricted Securities and is capable of evaluating the merits and risks of such investment and protecting himself in connection with the Purchase and an investment in the Restricted Securities. Such Seller has, to the extent deemed necessary by him retained, at his own expense, and relied upon, appropriate professional advice regarding the investment, tax and legal merits and consequences of an investment in the Restricted Securities. Such Seller has examined the SEC Documents, or caused the same to be examined, by his representatives to the extent he deems necessary or appropriate. Such Seller has not received any legal, business, tax or other advice from NGSG, its counsel or other representatives. e. Such Seller acknowledges that (i) it has been called to his attention that his investment in the Restricted Securities involves risk and (ii) he understands that the Restricted Securities to be issued in the Purchase will be an illiquid investment, subject to any future registration pursuant to this Agreement. f. No person or entity, other than NGSG, has been authorized to give any information or to make any representations on behalf of NGSG in connection with the Purchase, and, if given or made, such information or representations have not been relied upon by such Seller as having been made or authorized by NGSG. The only representations, warranties and information made by NGSG in connection with the Purchase are those contained in the Purchase Agreement and the SEC Documents. g. NGSG has provided such Seller the opportunity to ask questions of, and receive answers from, NGSG concerning the Purchase and the Restricted Securities and to obtain any appropriate additional information necessary to the investment decision being made by him in connection with the Purchase and the Restricted Securities. h. Such Seller acknowledges that he has been advised that: IN MAKING AN INVESTMENT DECISION REGARDING THE RESTRICTED SECURITIES, HE MUST RELY ON HIS OWN EXAMINATION OF NGSG AND THE TERMS OF THE PURCHASE, INCLUDING THE MERITS AND RISKS INVOLVED. THE RESTRICTED SECURITIES HAVE NOT BEEN RECOMMENDED BY ANY FEDERAL OR STATE SECURITIES COMMISSION OR REGULATORY AUTHORITY. THE RESTRICTED SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE, AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM. THE SECURITIES ARE ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFERABILITY SET FORTH IN THIS AGREEMENT. The foregoing representations and warranties and undertakings are made by and on behalf of each Seller with the intent that they be relied upon by NGSG in determining each Seller's suitability as an investor. Each Seller hereby agrees that such representations and warranties shall survive his purchase of the Restricted Securities. 2. Standstill. Unless waived in writing by NGSG from time to time, during the period commencing on the Closing Date and ending on the third anniversary thereof, neither Sellers nor any of their respective affiliates (as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended) will: (a) acquire or agree, offer, seek or propose to acquire (or request permission to do so), ownership (including, but not limited to, beneficial ownership as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended) of any assets or businesses or any additional securities issued by NGSG, or any rights or options to acquire such ownership (including from a third party), or (b) contest any election of directors by the stockholders of NGSG, or (c) otherwise act, alone or in concert with others, to induce or attempt to induce any other person to initiate any stockholder proposal or a tender offer for any voting secutrites of NGSG, or (d) enter into any discussions, negotiations, arrangements or understandings with any third party with respect to any of the foregoing. 3. Restrictions on Transferability; Registration Rights. The Restricted Securities shall not be transferable except upon the conditions specified in this Section 3; provided that, notwithstanding any other provision of this Section 3, each Seller shall have the right to transfer any Restricted Securities upon the prior written consent of NGSG. Each transferee shall be subject to the same transfer restrictions imposed on Sellers by this Agreement. All rights and obligations of Sellers set forth in this Section 3 will inure to the benefit of and be binding upon any transferee of the Restricted Securities. 3.1 Restrictive Legend. Unless and until otherwise permitted by this Section 3, each certificate for Restricted Securities issued under the Purchase Agreement, and each certificate for any Restricted Securities issued to any subsequent permitted transferee of any such certificate, shall be stamped or otherwise imprinted with a legend in substantially the following form: "The shares evidenced by this certificate have not been registered under the Securities Act of 1933, as amended, and may be reoffered and sold only if registered pursuant to the provisions of said Securities Act or if an exemption from registration is available." 3.2 Notice of Proposed Transfers. Prior to any transfer or attempted transfer of any Restricted Securities (other than pursuant to Rule 144 under the Securities Act or registration of the Restricted Securities under the Securities Act), the Seller of such Restricted Securities shall give written notice to NGSG of such Seller's intention to effect such transfer. Each such notice (i) shall describe the manner and circumstances of the proposed transfer in sufficient detail, and shall contain an undertaking by the Seller giving such notice to furnish such other information as may be required, to enable counsel to render the opinions referred to below, and (ii) shall designate the counsel for the Seller giving such notice. Such Seller shall obtain the services of counsel described below at his own expense. The Seller giving such notice shall submit a copy thereof to the counsel designated in such notice. If in the opinion of such counsel, which is reasonably satisfactory to NGSG, the proposed transfer of such Restricted Securities may be effected without registration of such Restricted Securities under the Securities Act, NGSG shall, within ten business days after delivery of such opinion to NGSG, so notify the Seller of such Restricted Securities and such Seller shall thereupon be entitled to transfer such Restricted Securities in accordance with the terms of the notice delivered by such Seller to NGSG. Each certificate evidencing the Restricted Securities thus to be transferred (and each certificate evidencing any untransferred balance of the Restricted Securities) shall bear the restrictive legend set forth in Section 3.1. 3.3 Piggy-Back Registration Rights. (a) Registration Initiated by NGSG. If NGSG shall determine to register any shares of common stock of NGSG (other than a registration relating to stock options or employee benefit plans, any dividend reinvestment plan, or the acquisition or purchase by or combination by merger or otherwise of NGSG of or with another company or business entity or partnership), whether or not for sale for its own account, NGSG will: (i) promptly give to Sellers written notice thereof (which shall include (to the extent known) a list of the jurisdictions in which NGSG intends to attempt to qualify such securities under the applicable blue sky or other state securities laws); and (ii) include in such registration (and any related qualification under blue sky laws or other compliance), and in any underwriting involved therein, all the Restricted Securities specified in a written request or requests, made within 20 days after receipt of such written notice from NGSG, by Sellers, except as set forth in Section 3.3(b) below. (b) Underwriting. If the registration of which NGSG gives notice to Sellers is for a registered public offering involving an underwriting, NGSG shall so advise Sellers as a part of the written notice given pursuant to Section 3.3(a)(i). In such event, the right of each Seller to registration pursuant to this Section 3.3 shall be conditioned upon each such Seller's participation in such underwriting and the inclusion of each such Seller's Restricted Securities in the underwriting to the extent provided herein. A Seller proposing to distribute shares of his Restricted Securities through such underwriting (together with NGSG and the other holders (if any) distributing their securities through such underwriting) shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by NGSG. Notwithstanding any other provision of this Section 3.3, if the lead managing underwriter determines, in good faith, that marketing factors require a limitation of the number of shares to be underwritten, the underwriter may limit the number of shares of Restricted Securities to be included in the registration and underwriting to the extent such underwriter deems necessary. NGSG shall so advise Sellers, and the number of shares of Restricted Securities that may be included in the registration and underwriting shall be reduced to the number which the underwriter is willing to include in the registration. If a Seller disapproves of the terms of any such underwriting, such Seller may elect to withdraw therefrom by written notice to NGSG and the underwriter. (c) Expenses of Registration by the Company. NGSG shall bear all expenses incurred in connection with each registration, qualification or compliance pursuant to this Section 3.3, including, without limitation, all registration, filing and qualification fees, printing expenses, audit fees, fees and disbursements of counsel for NGSG and counsel for the underwriters, if any (unless any such underwriter pays such counsel fees) and reasonable fees and disbursements of one special counsel for Sellers (but excluding underwriter's commissions, fees and expenses allocable to the Restricted Securities of Sellers and fees of independent accountants, if any, for Sellers, which commissions, fees and expenses and fees of accountants shall be borne pro rata (by share) by Sellers and any other offeror employing such accountants in such requested registration). (d) Limitations on Registration. NGSG's obligation to effect a registration under Section 3.3(a) shall expire two years from the date of consummation of the Purchase. Notwithstanding any provision to the contrary in this Section 3.3, NGSG shall not be obligated to take any action to effect any such registration, qualification or compliance pursuant to Section 3.3 on more than two occasions; provided, however, only registrations which actually include all of the Restricted Securities of Sellers requested to be included shall be counted for this purpose. (e) Assignability and Assumption. The registration rights granted to Sellers in this Section 3.3 may be assigned in whole or in part by the holder thereof in connection with any transfer of Restricted Securities provided that (i) the assignor provides NGSG with written notice of such assignment, and (ii) the assignee of such rights agrees in writing to be bound by the terms and conditions of this Section 3. In the event of a partial assignment, the holders of Restricted Securities shall possess the rights granted in this Section 3.3 pro rata in accordance with the number of shares of Restricted Securities beneficially owned by each of them and each such holder shall be entitled to receive a copy of all notices provided for in this Agreement and to exercise such part of the rights so granted. 3.4 Registration Procedures. In the case of each registration, qualification or compliance effected by NGSG pursuant to this Agreement pursuant to which Restricted Securities of Sellers are included therein, NGSG will keep Sellers advised in writing as to the initiation of each registration, qualification and compliance and as to the completion thereof. At its expense, NGSG will: (a) keep such registration, qualification or compliance effective for a period of at least 120 days or until Sellers have completed the distribution described in the registration statement relating thereto, whichever first occurs; (b) furnish such number of prospectuses and other documents incident thereto as Sellers from time to time may reasonably request; (c) list such Restricted Securities on each securities exchange (if any) on which the common stock of NGSG is listed; and (d) provide to Sellers and their special counsel a reasonable opportunity to review in advance the registration statement and all amendments thereto. 3.5 Indemnification. (a) NGSG shall, if Restricted Securities held by Sellers or any other holder of Restricted Securities are included in the securities as to which such registration, qualification or compliance is being effected, indemnify Sellers and each other holder of Restricted Securities, each of their officers and directors, and each person controlling any of Sellers or other holder of Restricted Securities, with respect to each registration, qualification or compliance which has been effected pursuant to Section 3.3, and each underwriter, if any, and each person who controls any underwriter, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any prospectus, offering circular or other document (including any related registration statement, notification or the like) incident to any such registration, qualification or compliance, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements not misleading, and will reimburse Sellers and each other holder of Restricted Securities, each of their officers and directors, and each person controlling any of Sellers or other holder of Restricted Securities, each such underwriter and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action; provided that NGSG will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission based upon written information furnished to NGSG by Sellers or other holder of Restricted Securities or underwriter specifically for use therein. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such party and shall survive the subsequent transfer of shares of common stock of NGSG by the seller thereof and the transfer of any shares of common stock of NGSG which were the subject of such registration, qualification or listing. (b) Each of the Sellers and each other holder of Restricted Securities, severally and not jointly, will, if Restricted Securities held by such Seller or other holder of Restricted Securities are included in the securities as to which such registration, qualification or compliance is being effected, indemnify NGSG, each of its directors and officers, each legal counsel and independent accountants of NGSG, each underwriter, if any, of NGSG's securities covered by such registration statement, each person who controls NGSG or such underwriter within the meaning of the Securities Act, and each other holder of common stock of NGSG registering securities of NGSG in such registration, each of its officers and directors and each person controlling such holder, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, prospectus, offering circular or other document, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse NGSG, such holders, such directors, officers, persons, underwriters or control persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to NGSG by such Seller or other holder of Restricted Securities specifically for use therein; provided; however, that (i) the obligations of each Seller and each other holder of Restricted Securities hereunder shall be limited to an amount equal to the proceeds to such Seller or each other holder of Restricted Securities sold as contemplated herein and (ii) the indemnity for untrue statements or omissions described above shall not apply if Sellers or other holder of Restricted Securities providing such written information provide NGSG with such additional written information prior to the effectiveness of the registration as is required to make the previously supplied written information true and complete, together with a description in reasonable detail of the information previously supplied which was untrue or incomplete. (c) Each person entitled to indemnification under this Section 3.5 (the "Indemnified Person") shall give notice to the party required to provide indemnification (the "Indemnifying Party") promptly after such Indemnified Person has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Person (whose approval shall not unreasonably be withheld), and the Indemnified Person may participate in such defense at such person's expense, and provided further that the failure of any Indemnified Person to give notice as provided herein shall not relieve the Indemnifying Party of any obligations it may have otherwise than on account of this Section 3.5. After notice from the Indemnifying Party to the Indemnified Person of its election to assume the defense of such claim or litigation, the Indemnifying Party will not be liable to such Indemnified Person for any legal or other expenses subsequently incurred by such Indemnified Person in connection with the defense thereof other than reasonable costs of investigation, unless the Indemnifying Party abandons the defense of such claim or litigation. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Person, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Person of a release from all liability in respect to such claim or litigation. (d) The indemnification required by this Section 3.5 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred. 3.6 Information by Sellers and Other Holders. Sellers or other holders of Restricted Securities included in any registration shall furnish to NGSG such information regarding Sellers or other holders and the distribution proposed by Sellers or other holders as NGSG may reasonably request in writing, and as shall be required in connection with any registration, qualification or compliance referred to in this Agreement. 4.

Hensley shall be appointed to fill the vacancy existing on the Board of Directors at the date hereof, to hold office until the next annual stockholders' meeting at which directors are elected, and in connection with the next annual meeting of stockholders, NGSG will nominate Paul D. Hensley for election as a director to serve for a term the same as the class of directors then standing for election. 5. Miscellaneous.

(b) This Agreement constitutes the entire agreement among the parties hereto with respect to the subject matter hereof, and may be amended only by a writing executed by all parties hereto.
