                        NATURAL GAS SERVICES GROUP, INC.

         The undersigned,  who, if a natural person, is eighteen years of age or
older,  hereby  establishes  a  corporation  pursuant to the  Colorado  Business
Corporation Act, as amended, and adopts the following Articles of Incorporation:

                                   ARTICLE I.
                                      NAME

         The name of the corporation is Natural Gas Services Group, Inc.

                                   ARTICLE II.
                               AUTHORIZED CAPITAL
                                AND SHAREHOLDERS

         1. The  aggregate  number of shares  which the  corporation  shall have
authority  to issue is  30,000,000  shares of $0.01 par value  common  stock and
5,000,000  shares of $0.01 par value preferred stock. The preferred stock may be
issued in any number of series,  as determined  by the board of  directors.  The
board of directors may by resolution fix the designation and number of shares of
any such series and may determine,  alter or revoke the rights, including voting
rights,  preferences,  privileges  and  restrictions  pertaining  to any  wholly
unissued  shares.  The board of  directors  may  thereafter  in the same  manner
increase or decrease  the number of shares of any such series (but not below the
number of shares of that series then outstanding).

         2. Each  shareholder  of record  shall  have one vote for each share of
stock standing in the  shareholder's  name on the books of the  corporation  and
entitled to vote,  except that in the  election of  directors  each  shareholder
shall have as many votes for each share held by him as there are directors to be
elected and for whose election the shareholder  has a right to vote.  Cumulative
voting shall not be permitted in the election of directors or otherwise.

         3. Unless otherwise  ordered by a court of competent  jurisdiction,  at
all meetings of shareholders a majority of the shares of a voting group entitled
to vote at such meeting,  represented in person or by proxy,  shall constitute a
quorum of that voting group.

         4.  Except as bylaws  adopted by the  shareholders  may  provide  for a
greater voting requirement and except as otherwise set forth herein, action on a
matter is approved if a quorum  exists and if the votes cast favoring the action
exceed the votes  cast  opposing  the  action.  Any bylaw  adding,  changing  or
deleting a greater quorum or voting  requirement for shareholders shall meet the
same quorum  requirement and be adopted by the same vote required to take action
under the  quorum  and  voting  requirements  then in effect or  proposed  to be
adopted, whichever are greater.




         5. Any action  required or permitted to be taken by shareholders of the
corporation  must be taken at a duly  called  annual or special  meeting of such
shareholders and may not be taken by consent in writing by such shareholders.

         The Board of  Directors  shall be divided  into three (3) groups,  each
group to be as  nearly  equal in  number  as  possible.  The  terms of office of
directors  of the first  group are to expire  at the  first  annual  meeting  of
shareholders  after their election,  the terms of office of the second group are
to expire at the second annual  meeting after their  election,  and the terms of
office of the third group are to expire at the third annual  meeting after their
election. Thereafter, each director shall serve for a term ending on the date of
the third annual meeting of  shareholders  following the annual meeting at which
such  director  was  elected.  This  provision  setting  forth the  division  of
directors  into three groups  cannot be amended or repealed by the directors and
cannot be amended or repealed  without the affirmative vote of the holders of at
least 80% of the votes entitled to be cast in the election of directors.

                                  ARTICLE VIII.
                        LIMITATION ON DIRECTOR LIABILITY

         A director of the  corporation  shall not be  personally  liable to the
corporation or to its  shareholders for monetary damages for breach of fiduciary
duty as a director.  However,  this  provision  shall not eliminate or limit the
liability of a director to the corporation or to its  shareholders  for monetary
damages otherwise  existing for (i) any breach of the director's duty of loyalty
to the  corporation or to its  shareholders;  (ii) acts or omissions not in good
faith or which involve  intentional  misconduct  or a knowing  violation of law;
(iii) acts specified in Section 7-108-403 of the Colorado  Business  Corporation
Act, as it may be amended from time to time; or (iv) any transaction  from which
the director directly or indirectly  derived any improper  personal benefit.  If
the Colorado Business Corporation Act is hereafter amended to eliminate or limit
further the liability of a director,  then, in addition to the  elimination  and
limitation  of liability  provided by the preceding  sentence,  the liability of
each director shall be eliminated or limited to the fullest extent  permitted by
the Colorado Business  Corporation Act as so amended. Any repeal or modification
of this Article VIII shall not  adversely  affect any right or  protection  of a
director of the  corporation  under this Article VIII, as in effect  immediately




prior to such repeal or  modification,  with respect to any liability that would
have accrued,  but for this Article VIII,  prior to such repeal or modification.
Nothing  contained  herein  will be  construed  to deprive  any  director of the
director's  right to all  defenses  ordinarily  available to a director nor will
anything  herein be  construed to deprive any director of any right the director
may have for contribution from any other director or other person.

                                   ARTICLE IX.
              CONFLICTING INTEREST TRANSACTIONS AND INDEMNIFICATION

         The  following  provisions  are  inserted  for  the  management  of the
business and for the conduct of the affairs of the  corporation and the same are
in furtherance of and not in limitation or exclusion of the powers  conferred by
law.

         1.  Conflicting  Interest  Transactions.  As used  in  this  paragraph,
"conflicting  interest  transaction"  means any of the following:  (i) a loan or
other  assistance by the  corporation to a director of the  corporation or to an
entity in which a director of the  corporation is a director or officer or has a
financial  interest;  (ii) a guaranty by the  corporation  of an obligation of a
director of the corporation or of an obligation of an entity in which a director
of the  corporation  is a director  or officer or has a financial  interest;  or
(iii) a contract or transaction  between the  corporation  and a director of the
corporation or between the  corporation and an entity in which a director of the
corporation is a director or officer or has a financial interest. No conflicting
interest  transaction  shall be void or voidable,  be enjoined,  be set aside or
give  rise to an award  of  damages  or other  sanctions  in a  proceeding  by a
shareholder  or by or in  the  right  of  the  corporation  solely  because  the
conflicting  interest  transaction  involves a director of the corporation or an
entity in which a director of the  corporation is a director or officer or has a
financial  interest or solely because the director is present at or participates
in the meeting of the  corporation's  board of directors or of the  committee of
the board of  directors  which  authorizes,  approves or ratifies a  conflicting
interest  transaction or solely because the director's  vote is counted for such
purpose if: (A) the material facts as to the director's relationship or interest
and as to the conflicting interest transaction are disclosed or are known to the
board of directors or the  committee  and the board of directors or committee in
good faith authorizes, approves or ratifies the conflicting interest transaction
by the  affirmative  vote of a majority  of the  disinterested  directors,  even
though the  disinterested  directors are less than a quorum; or (B) the material
facts as to the director's  relationship  or interest and as to the  conflicting
interest transaction are disclosed or are known to the shareholders  entitled to
vote  thereon  and  the   conflicting   interest   transaction  is  specifically
authorized, approved or ratified in good faith by a vote of the shareholders; or
(C) the conflicting interest transaction is fair as to the corporation as of the
time it is  authorized,  approved  or  ratified  by the  board of  directors,  a
committee  thereof or the  shareholders.  Common or interested  directors may be
counted in  determining  the  presence  of a quorum at a meeting of the board of
directors  or  of  a  committee  which  authorizes,  approves  or  ratifies  the
conflicting interest transaction.

         2. Loans and Guaranties for the Benefit of Directors. Neither the board
of directors nor any committee thereof shall authorize a loan by the corporation
to a director  of the  corporation  or to an entity in which a  director  of the
corporation is a director or officer or has a financial  interest or authorize a




guaranty by the corporation of an obligation of a director of the corporation or
of an  obligation  of an  entity in which a  director  of the  corporation  is a
director or officer or has a financial  interest,  until at least ten days after
written  notice of the proposed  authorization  of the loan or guaranty has been
given to the  shareholders who would be entitled to vote thereon if the issue of
the  loan  or  guaranty  were  submitted  to a  vote  of the  shareholders.  The
requirements  of this  paragraph 2 are in addition  to, and not in  substitution
for, the provisions of paragraph 1 of this Article IX.

         3.  Indemnification.  The corporation  shall indemnify,  to the maximum
extent  permitted by law in effect from time to time, any person who is or was a
director,  officer,  agent, fiduciary or employee of the corporation against any
claim,  liability  or expense  arising  against or  incurred by such person made
party to a proceeding because such person is or was a director,  officer, agent,
fiduciary  or  employee  of the  corporation  or because  such  person is or was
serving  another  entity as a director,  officer,  partner,  trustee,  employee,
fiduciary or agent at the corporation's  request.  The corporation shall further
have the  authority  to the maximum  extent  permitted  by law to  purchase  and
maintain insurance providing such indemnification.

         4. Negation of Equitable Interests in Shares or Rights. Unless a person
is recognized as a shareholder through procedures established by the corporation
pursuant to Section  7-107-204 of the Colorado  Business  Corporation Act or any
similar law, the corporation shall be entitled to treat the registered holder of
any shares of the corporation as the owner thereof for all purposes permitted by
the Colorado Business Corporation Act including,  without limitation, all rights
deriving from such shares,  and the corporation  shall not be bound to recognize
any equitable or other claim to, or interest in, such shares or rights  deriving
from such shares on the part of any other person including,  without limitation,
a purchaser,  assignee or transferee of such shares, unless and until such other
person  becomes the  registered  holder of such shares or is recognized as such,
whether or not the corporation  shall have either actual or constructive  notice
of the  claimed  interest  of such other  person.  By way of example  and not of
limitation,  until such other  person has become the  registered  holder of such
shares or is recognized  pursuant to Section  7-107-204 of the Colorado Business
Corporation  Act or  any  similar  applicable  law,  such  person  shall  not be
entitled:  (i) to receive  notice of the meetings of the  shareholders;  (ii) to
vote at such meetings;  (iii) to examine a list of the shareholders;  (iv) to be
paid dividends or other  distributions  payable to shareholders;  or (v) to own,
enjoy and  exercise  any other  rights  deriving  from such  shares  against the
corporation.   Nothing  contained  herein  will  be  construed  to  deprive  any
beneficial  shareholder,  as  defined in Section  7-113-101(1)  of the  Colorado
Business  Corporation  Act,  as  amended  from time to time,  of any right  such
beneficial shareholder may have pursuant to Article 113 of the Colorado Business
Corporation Act or any similar law subsequently enacted.

                            ARTICLES OF INCORPORATION

                        NATURAL GAS SERVICES GROUP, INC.


         Pursuant to the provisions of the Colorado  Business  Corporation  Act,
the undersigned  Corporation  adopts the following  Articles of Amendment to its
Articles of Incorporation:

         FIRST: The name of the Corporation is Natural Gas Services Group, Inc.

         SECOND: The following  amendments to the Articles of Incorporation were
duly  adopted by the board of directors on July 25,  2001,  in  accordance  with
Section 7-106-102 of the Colorado Business Corporation Act.

         Article II of the Articles of Incorporation is hereby amended by adding
the following Section II.6:

                  Section  11.6  Convertible  Series A Preferred  Stock.  Of the
         5,000,000 shares of the  Corporation's  $0.01 par value preferred stock
         authorized, 1,177,000 shares of the Corporation's preferred stock shall
         consist  of 10%  Convertible  Series A  Preferred  Stock  ("Convertible
         Series  A" ). The  rights,  preferences,  privileges  and  restrictions
         imposed upon the Convertible Series A are as follows:

                           (a) Dividends.  The holders of the Convertible Series
                  A  shall  be  entitled  to  receive,  out  of  fluids  legally
                  available  therefor,  cumulative  dividends at the rate of 10%
                  percent of the  Liquidation  Value per annum in cash, when and
                  if  declared  by  the  Board  of  Directors   which  shall  be
                  preferential  to  dividends  on  any  Junior  Securities.  The
                  dividend  on  the  Convertible   Series  A  shall  be  payable
                  quarterly  beginning  30 days  after the last day of the first
                  calendar quarter after the issuance of the Convertible  Series
                  A  ("Original  Issue  Date") and 30 days after the end of each
                  calendar quarter thereafter, when and if declared by the Board
                  of Directors. Any dividends earned on the Convertible Series A
                  from the Original  Issue Date to the end of the first calendar
                  quarter  after the  Original  Issue Date,  shall be earned pro
                  rata from the Original Issue Date.

                           If any dividends payable on the Convertible  Series A
                  are not paid for any  reason,  the right of the holders of the
                  Convertible  Series A to  receive  payment  of such  dividends
                  shall not lapse or terminate,  but said unpaid dividends shall
                  accumulate  and shall be paid without  interest to the holders
                  of the Convertible Series A, when and if declared by the Board
                  of Directors of the Corporation,  before any sum or sums shall
                  be set aside for or applied to the purchase or  redemption  of
                  the Convertible Series A or the purchase,  redemption or other




                  acquisition for value of any Junior  Securities and before any
                  dividend shall be paid or declared,  or any other distribution
                  shall be ordered or made,  upon any Junior  Securities.  After
                  cumulative  dividends on the Convertible Series A for all past
                  dividend periods and for the then current year dividend period
                  shall have been  declared and paid or set apart,  if the Board
                  of  Directors  may  declare  dividends  out of  funds  legally
                  available therefor,  such additional dividends may be declared
                  on any Junior Securities.  "Junior  Securities" as used herein
                  means any of the  Corporation's  equity  securities other than
                  the Convertible Series A shares.

                           (b) Liquidation and  Dissolution.  Upon the voluntary
                  or involuntary  liquidation,  winding up or dissolution of the
                  Corporation,  out of the assets  available for distribution to
                  shareholders  each  share  of  Convertible  Series  A shall be
                  entitled  to  receive,  in  preference  to any  payment on any
                  Junior Securities of the Corporation, an amount equal to three
                  dollars  and  twenty-five   cents  ($3.25)  per  share,   plus
                  cumulative  dividends  as provided in Section  II.6(a) of this
                  Article  II  accrued  and  unpaid to the date  payment is made
                  available  to  the  Convertible  Series  A  (the  "Liquidation
                  Value").  After the full preferential  liquidation  amount has
                  been paid to, or  determined  and set apart  for,  Convertible
                  Series A, the remaining assets shall be payable to the holders
                  of the  Corporation's  Junior  Securities.  In the  event  the
                  assets of the  Corporation  are  insufficient  to pay the full
                  preferential  liquidation  amount  required  to be paid to the
                  Convertible  Series A, the Convertible  Series A shall receive
                  such funds pro rata on a share for share  basis until the full
                  liquidating  preference on the Convertible Series A is paid in
                  full.

                           A reorganization  described in (d)(iv)(6) below shall
                  not  be  considered  to  be  a  liquidation,   winding  up  or
                  dissolution within the meaning of this Section II.6(b) of this
                  Article II and the Convertible Series A shall be entitled only
                  to the rights provided in the plan of reorganization.

                           (c) Voting. A holder of a share of Convertible Series
                  A shall  be  entitled  to one  vote  on any  and all  matters,
                  including  the  election of  directors,  and shall,  except as
                  otherwise  may be  provided  by law,  vote as a class with the
                  holders of outstanding Common Stock.

                           (d)  Conversion  Rights.  The holders of  Convertible
                  Series A have the following conversion rights (the "Conversion
                  Rights"):

                                    (i) Right to  Convert.  Subject to any prior
                           automatic    conversion    under    subsection   (ii)
                           immediately below, each share of Convertible Series A
                           shall be convertible at the option of the holder,  at
                           the  office  of the  Corporation  or of any  transfer
                           agent for such Convertible  Series A, as the case may
                           be,  into  fully  paid and  nonassessable  shares  of
                           Common  Stock,  at a  conversion  price of $3.25  per
                           share,  subject to  adjustment  pursuant to paragraph
                           (d)(iv) below ("Conversion Price").




                                    (ii)  Automatic  Conversion.  Each  share of
                           Convertible Series A shall be automatically converted
                           into  Common  Stock if, at any time  after six months
                           from the  completion  of the  first  offering  by the
                           Corporation,  pursuant  to a  registration  statement
                           declared  effective by the United  States  Securities
                           and Exchange Commission,  the closing market price of
                           the  Common  Stock  equals  or  exceeds  200%  of the
                           Conversion  Price for 20  consecutive  trading  days.
                           Upon the  occurrence  of such  event,  each  share of
                           Convertible  Series A shall be  converted  into fully
                           paid and nonassessable  shares of Common Stock at the
                           Conversion Price.

                                    (iii)  Mechanics of  Conversion.  Before any
                           holder  of shares  of  Convertible  Series A shall be
                           entitled  to  convert  the same into  full  shares of
                           Common Stock pursuant to paragraph  (d)(i) above, the
                           holder   shall    surrender   the    certificate   or
                           certificates  therefor,  duly endorsed, at the office
                           of the  Corporation or of any transfer agent for such
                           Convertible  Series A, as the case may be,  and shall
                           give written notice to the Corporation at such office
                           that the holder  elects to convert the same and shall
                           state  therein the holder's name or the name or names
                           of the holder's  nominees in which the holder  wishes
                           the certificate or certificates  for shares of Common
                           Stock to be issued. The Corporation shall, as soon as
                           practicable thereafter, issue and deliver or cause to
                           be  issued  and  delivered  at  such  office  to such
                           holder,  or to the holder's  nominee or  nominees,  a
                           certificate  or  certificates  for the number of full
                           shares of Common  Stock to which the holder  shall be
                           entitled  as  aforesaid.  A  conversion  pursuant  to
                           paragraph  (d)(i)  above  shall  be  deemed  to  have
                           occurred  immediately  prior to the close of business
                           on the  date  of  such  surrender  of the  shares  of
                           Convertible Series A to be converted,  and the person
                           or persons  entitled  to receive the shares of Common
                           Stock issuable upon such conversion  shall be treated
                           for all  purposes as the record  holder or holders of
                           such shares of Common Stock on such date.

                                    Upon  automatic  conversion  of  Convertible
                           Series A into full shares of Common Stock pursuant to
                           paragraph   (d)(ii)   above,   the   holder   of  the
                           Convertible  Series  A  shall,  upon  request  by the
                           Corporation,    surrender    the    certificate    or
                           certificates  therefor,  duly endorsed, at the office
                           of the  Corporation  or any  transfer  agent for such
                           Convertible  Series A, as the case may be,  and shall
                           state  therein the holder's name or the name or names
                           of the holder's  nominees in which the holder  wishes
                           the certificate or certificates  for shares of Common
                           Stock to be issued. The Corporation shall, as soon as
                           practicable thereafter, issue and deliver or cause to
                           be  issued  and  delivered  at  such  office  to such
                           holder,  or to the holder's  nominee or  nominees,  a
                           certificate  or  certificates  for the number of full
                           shares of Common  Stock to which the holder  shall be
                           entitled as aforesaid.




                                    Each  holder  of the  Convertible  Series  A
                           whose  Convertible  Series A is  converted  to Common
                           Stock shall be entitled to, and the Corporation shall
                           promptly pay in cash,  or set aside for payment,  all
                           unpaid  dividends  with  respect  to  such  converted
                           shares of the  Convertible  Series  A,  earned to and
                           including  the date of  conversion.  A holder  of the
                           Convertible  Series A shall  not be  entitled  to any
                           remaining  dividends with respect to the  Convertible
                           Series  A so  converted,  but  shall be  entitled  to
                           receive,   on  the  date  of  the   conversion,   the
                           arrearages, if any, with respect to any shares of the

                           this paragraph  (d), the "Original  Issue Date" shall
                           mean,   the  original   date  on  which  a  share  of
                           Convertible  Series A was  first  issued to each such
                           shareholder and "Market Price" shall be determined as

                                             a) if the  Common  Stock is  listed
                                    and  registered  on any national  securities
                                    exchange  or  traded  on  The  Nasdaq  Stock
                                    Market ("Nasdaq"), the closing bid price;

                                             b) if such  Common  Stock is not at
                                    the  time  listed  on any such  exchange  or
                                    traded  on  Nasdaq  but is traded on the OTC
                                    Bulletin  Board,  or if  not,  on  the  over
                                    the-counter   market  as   reported  by  the
                                    National    Quotation    Bureau   or   other
                                    comparable  service,  the  closing bid price
                                    for such stock; or

                                             c) if  clauses  a) and b) above are
                                    not applicable,  the fair value per share of
                                    such  Common  Stock  as  determined  in good
                                    faith and on a reasonable basis by the Board
                                    of Directors of the Corporation.

                           Combinations. If the Corporation shall at any time or
                           from  time to time  after  the  Original  Issue  Date

                           immediately   before   that   subdivision   shall  be
                           proportionately  decreased  and,  conversely,  if the
                           Corporation  shall at any  time or from  time to time

                           Conversion  Price then in effect  immediately  before
                           the combination shall be  proportionately  increased.
                           Any adjustments under this paragraph (d)(iv)(2) shall
                           become effective at the close of business on the date

                                    (3)  Adjustment  for Certain  Dividends  and
                           Distributions.  In the event the  Corporation  at any
                           time, or from time to time,  after the Original Issue

                           the determination of holders of Common Stock entitled
                           to receive, a dividend or other distribution  payable
                           in shares of Common Stock, then and in each event the
                           applicable  Conversion  Price then in effect shall be
                           decreased as of the time of such  issuance or, in the
                           event such a record date shall have been fixed, as of
                           the  close  of  business  on  such  record  date,  by
                           multiplying the Conversion  Price then in effect by a
                           fraction:

                                             a) the  numerator of which shall be
                                    the total  number of shares of Common  Stock
                                    issued and outstanding  immediately prior to
                                    the time of such  issuance  or the  close of
                                    business on such record date, and

                                             b) the  denominator  of which shall
                                    be the  total  number  of  shares  of Common
                                    Stock  issued  and  outstanding  immediately
                                    prior  to the time of such  issuance  or the
                                    close of  business  on such record date plus
                                    the   number  of  shares  of  Common   Stock
                                    issuable  in  payment  of such  dividend  or
                                    distribution;  provided,  however,  if  such
                                    record  date  shall have been fixed and such
                                    dividend  is  not  fully  paid  or  if  such
                                    distribution  is not fully  made on the date
                                    fixed therefor,  the Conversion  Price shall
                                    be recomputed accordingly as of the close of
                                    business on such record date and  thereafter
                                    such  Conversion  Price  shall  be  adjusted
                                    pursuant to this paragraph  (d)(iv)(3) as of
                                    the time of actual payment of such dividends
                                    or distributions.

                           Distributions.  In the event the  Corporation  at any
                           time or from time to time  after the  Original  Issue
                           Date  shall make or issue,  or fix a record  date for
                           the determination of holders of Common Stock entitled
                           to receive, a dividend or other distribution  payable
                           in securities of the Corporation other than shares of
                           Common Stock, then and in such event provisions shall
                           be made so that the holders of  Convertible  Series A
                           shall receive upon conversion  thereof in addition to
                           the  number  of shares  of  Common  Stock  receivable
                           thereon,  the amount of securities of the Corporation
                           which they would have received had their  Convertible
                           Series A been converted into Common Stock on the date
                           of such event and had  thereafter,  during the period
                           from the  date of such  event  to and  including  the
                           conversion date,  retained such securities  (together
                           with any  distributions  payable  thereon during such
                           period)  receivable by them as aforesaid  during such
                           period,  giving application to all adjustments called
                           for during such period under this  paragraph (d) with
                           respect  to  the   rights  of  the   holders  of  the
                           Convertible Series A.

                           Original  Issue Date,  shall be changed into the same
                           or different number of shares of any class or classes
                           of  stock,   whether   by   capital   reorganization,

                           (3)    above,    or   a    reorganization,    merger,

                           paragraph  (d)(iv)(6)  below,  then, and in each such
                           event, provisions shall be made (by adjustment to the
                           Conversion  Price or otherwise) so that the holder of
                           each  share of  Convertible  Series A shall  have the
                           right thereafter to convert each share of Convertible
                           Series A into the kind and  amount of shares of stock
                           and   other    securities    receivable   upon   such
                           reorganization, reclassification, or other change, by
                           holders of the number of shares of Common  Stock into
                           which such share of  Convertible  Series A might have
                           been    converted    immediately    prior   to   such
                           reorganization,   reclassification,  or  change,  all
                           subject to further adjustment as provided herein.

                           Corporation  (other than a subdivision,  combination,

                           assets to any other person or entity, then, as a part
                           of such  reorganization,  merger,  consolidation,  or
                           sale,  provision  shall be made (by adjustment to the
                           Conversion Price or otherwise) so that the holders of
                           the Convertible Series A shall thereafter be entitled
                           to receive upon conversion of the Convertible  Series
                           A, the  number  and kind of  shares of stock or other
                           securities or property of the Corporation,  or of any
                           successor  corporation  resulting from such merger or
                           consolidation  or sale,  to which a holder  of Common
                           Stock  deliverable  upon  conversion  of such  shares
                           would   have   been    entitled   if   such   capital
                           reorganization,   merger,   consolidation,   or  sale
                           occurred on the date of the conversion.

                           Stock. If the Corporation completes a public offering

                           Conversion   Price,  the  Conversion  Price  will  be
                           reduced to the price at which such public offering is
                           completed.

                           Corporation should at any time receive any investment

                           time  that the  investment  is made,  the  Conversion
                           Price  shall  be  automatically  adjusted  to a price

                           (i) the sum of (x) the  number  of  shares  of Common
                           Stock   outstanding   immediately   prior   to   such
                           investment  multiplied  by the  Conversion  Price  in

                                    issue only of the number of shares of Common

                                    such shares of Common  Stock or  Convertible
                                    Securities  shall  be  deemed  to have  been

                                    of such shares of Common  Stock  immediately
                                    prior to the close of  business  on the date
                                    fixed  for  the  determination  of  security
                                    holders  entitled to receive  such shares of
                                    Common  Stock.  In case any shares of Common
                                    Stock  or  Convertible  Securities  shall be
                                    issued   together   with   other   stock  or
                                    securities    or   other   assets   of   the
                                    Corporation for consideration,  the Board of
                                    Directors of the Corporation shall determine
                                    what part of the  consideration  so received
                                    is to be deemed to be consideration  for the
                                    issue  of such  shares  of  Common  Stock or
                                    Convertible Securities. (D) Determination of
                                    Date of Issue. In case the Corporation shall
                                    take a record  of the  holders  of shares of
                                    Common  Stock for the  purpose of  entitling
                                    them  (i) to  receive  a  dividend  or other
                                    distribution  payable  in  shares  of Common

                                    such  record  date shall be deemed to be the
                                    date of the  issue or sale of the  shares of
                                    Common  Stock  deemed to have been issued or
                                    sold upon the  declaration  of such dividend
                                    or the making of such other  distribution or
                                    the date of the  granting  of such  right of
                                    subscription  or  purchase,  as the case may
                                    be.

                  shares of Convertible  Series A, including without  limitation
                  any  tax or  other  charge  imposed  in  connection  with  any
                  transfer  involved  in the  issue  and  delivery  of shares of
                  Common  Stock in a name other than that in which the shares of

                  the remaining unissued authorized shares of Common Stock shall
                  not be  sufficient  to  permit  the  conversion  of all of the
                  Convertible Series A at the time outstanding.

                           (xii)  Retirement of Convertible  Series A Converted.
                  No shares  of  Convertible  Series A that have been  converted
                  shall ever again be reissued, and all such shares so converted
                  shall,  upon  such  conversion,  cease  to be a  part  of  the
                  authorized shares of the Corporation.

         A shall be entitled as of right to subscribe for, purchase,  or receive
         any part of any new or additional  shares of any class,  whether now or
         hereafter authorized,  or of bonds,  debentures,  or other evidences of
         indebtedness  convertible into or exchangeable for shares of any class,
         but  all  such  new or  additional  shares  of  any  class,  or  bonds,
         debentures,  or other  evidences of  indebtedness  convertible  into or

         permitted  by law),  and to such  person  or  persons  as the  Board of
         Directors in their absolute discretion may deem advisable.

                  (f)   Replacement.   Upon   receipt  of  evidence   reasonably
         satisfactory to the Corporation (an affidavit of the registered  holder
         will be satisfactory) of the ownership and the loss, theft, destruction
         or  mutilation  of any  certificate  evidencing  Convertible  Series  A
         shares,  and in the case of any such loss,  theft or destruction,  upon
         receipt of indemnity reasonably satisfactory to the Corporation, or, in
         the case of any such mutilation upon surrender of such certificate, the
         Corporation  will (at its expense)  execute and deliver in lieu of such
         certificate a new certificate of like kind  representing  the number of
         Convertible Series A shares represented by such lost, stolen, destroyed
         or  mutilated  certificate  and  dated the date of such  lost,  stolen,
         destroyed or mutilated certificate.
