                                   ARTICLE IV

                               Board of Directors

         A.       Number, Election and Term of Directors. The business and 
     affairs of the Corporation  shall be managed by or under the direction of a
Board of  Directors  consisting  of not less than  three  nor more  than  eleven
directors,  the exact number of directors to be determined  from time to time by
resolution  adopted by a majority  of the total  number of  directors  which the
Corporation  would have if there were no vacancies (the "Whole Board") or by the
affirmative  vote of at least eighty  percent (80%) of the votes  entitled to be
cast by the Voting Stock.  Commencing  with the first  shareholders'  meeting at
which directors are elected, the directors,  other than those who may be elected
by the  holders  of any class or  series  of  Preferred  Stock  under  specified
circumstances,  shall be  divided,  with  respect  to the time  for  which  they
severally  hold  office,  into  three  classes,  as  nearly  equal in  number as

1997 annual meeting of  shareholders,  the term of office of the second class to
expire at the 1998 annual meeting of shareholders, and the term of office of the
third  class to expire at the 1999  annual  meeting of  shareholders,  with each
director to hold office  until his  successor  shall have been duly  elected and
qualified.  At each annual  meeting of  shareholders,  commencing  with the 1997
annual  meeting,  (i) directors  elected to succeed those  directors whose terms
then  expire  shall be  elected  for a term of  office  to  expire  at the third
succeeding  annual  meeting of  shareholders  after  their  election,  with each
director to hold office  until his  successor  shall have been duly  elected and
qualified,  and (ii) if  authorized  by a resolution  of the Board of Directors,
directors  may be  elected  to fill  any  vacancy  on the  Board  of  Directors,
regardless of how such vacancy shall have been created.

        B.        Shareholder Nomination of Director Candidates; Introduction of
Business.  Advance  notice  of  shareholder  nominations  for  the  election  of
directors  and of business to be brought by  shareholders  before any meeting of

Bylaws of the Corporation.

         C.       Newly Created Directorships and Vacancies. Subject to 
applicable  law and to the  rights  of the  holders  of any  class or  series of
Preferred  Stock with  respect to such class or series of Preferred  Stock,  and
unless the Board of Directors otherwise determines,  newly created directorships
resulting  from any  increase  in the  authorized  number  of  directors  or any
vacancies  on  the  Board  of  Directors  resulting  from  death,   resignation,
retirement, disqualification, removal from office or other cause shall be filled
only by a majority  vote of the  directors  then in office,  though  less than a
quorum,  and a director so chosen  shall hold office for a term  expiring at the
next  meeting of  shareholders  at which  directors  are  elected  and until his
successor shall have been duly elected and qualified.  No decrease in the number
of authorized directors constituting the entire Board of Directors shall shorten
the term of any incumbent director.

         D.       Removal.  Subject to the rights of the holders of any class or
series of  Preferred  Stock with  respect  to such class or series of  Preferred
Stock,  any  director,  or the entire  Board of  Directors,  may be removed from
office at any time, but only for cause and only by the  affirmative  vote of the
holders of at least eighty percent (80%) of the votes entitled to be cast by the
Voting Stock.

         E.       Amendment, Repeal or Alteration. Notwithstanding any other 
provision of these Articles or any provision of law which might otherwise permit
a lesser vote or no vote, but in addition to any affirmative vote of the holders
of any particular  class or series of the capital stock required by law or these
Articles,  the affirmative  vote of the holders of at least eighty percent (80%)
of the votes entitled to be cast by the Voting Stock shall be required to alter,
amend or repeal this Article IV.

                                    ARTICLE V

                    Amendment, Repeal or Alteration of Bylaws

         In  furtherance  and not in limitation of the powers  conferred by law,
the Board of Directors is expressly  authorized to make, alter, amend and repeal
the  Bylaws  of the  Corporation,  subject  to the power of the  holders  of the
capital stock of the Corporation to alter, amend or repeal the Bylaws; provided,
however,  that,  with  respect to the powers of the holders of capital  stock to
alter, amend and repeal the Bylaws of the Corporation, notwithstanding any other
provision of these Articles or any provision of law which might otherwise permit
a lesser vote or no vote, but in addition to any affirmative vote of the holders
of any  particular  class or  series  of the  capital  stock of the  Corporation
required by law or these  Articles,  the  affirmative  vote of the holders of at
least eighty  percent (80%) of the votes entitled to be cast by the Voting Stock
shall be required to (i) alter,  amend or repeal any provision of the Bylaws, or
(ii) alter, amend or repeal any provision of this Article V.

                                   ARTICLE VI

                        Special Meetings of Shareholders

         Subject  to the  rights  of the  holders  of any  class  or  series  of
Preferred Stock with respect to such class or series of Preferred Stock, special
meetings of  shareholders  of the Corporation may be called only by the Chairman
of the Board or by the Board of Directors  pursuant to a resolution adopted by a
majority  of the  Whole  Board.  Notwithstanding  any other  provision  of these
Articles or any provision of law which might  otherwise  permit a lesser vote or
no  vote,  but in  addition  to any  affirmative  vote  of  the  holders  of any
particular  class or series of the capital stock of the Corporation  required by
law or these Articles,  the  affirmative  vote of the holders of at least eighty
percent  (80%) of the votes  entitled  to be cast by the Voting  Stock  shall be
required to alter, amend or repeal this Article VI.

                                   ARTICLE VII

                       Interested Shareholder Transactions

         In the event that the holders of the capital  stock of the  Corporation
are  entitled  to vote on (i) a merger  or  consolidation  with any  Person  (as
hereinafter  defined)  or on a  proposal  that the  Corporation  sell,  lease or
exchange  substantially  all of its assets and property to or with any Person or
that any Person  sell,  lease or  exchange  substantially  all of its assets and
property to or with the Corporation, and such Person is the Beneficial Owner (as
hereinafter  defined) of shares  representing  ten percent  (10%) or more of the
votes entitled to be cast by the Voting Stock (an "Interested  Shareholder")  at
the  record  date  for  determining  shareholders  entitled  to vote or (ii) any
reclassification  of  securities,  recapitalization,  share  exchange  or  other
transaction (except redemptions  permitted by the terms of the security redeemed
or repurchases of the securities for cancellation or the Corporation's treasury)
designed to decrease  the number of holders of the  Corporation's  Common  Stock
remaining after any Person has become an Interested Shareholder, the affirmative
vote of the holders of at least eighty percent (80%) of the votes entitled to be
cast by the Voting  Stock shall be required for the approval of any such action,
in addition to any other approval that may be required by law or these Articles,
provided,  however,  that the  foregoing  shall  not  apply to any such  merger,
consolidation,   sale,  lease  or  exchange  of  assets  and  property  or  such
reclassification,  recapitalization,  share exchange or other  transaction which
was approved by resolutions of the Board of Directors of the  Corporation  prior
to the time that any Person becomes an Interested Shareholder or, in the case of
any  merger,  consolidation,  sale,  lease or exchange  involving  a  particular
Interested Shareholder,  prior to the time such Interested Shareholder became an
Interested Shareholder.

         For  the  purpose  hereof,  a  Person  shall  be  deemed  not  to be an
Interested Shareholder if (i) on the effective date of the certificate of merger
between the Corporation and Air Resources  Corporation,  a Colorado corporation,
such Person was the Beneficial Owner of shares representing ten percent (10%) or


                                       -4-




more of the votes  entitled to be cast by the Voting Stock,  or (ii) such Person
became the Beneficial  Owner of such shares as a result of acquiring shares from
a Person specified in (i) by gift,  testamentary  bequest or the laws of descent
and  distribution or in a transaction in which  consideration  was not exchanged
and  who  has  continued  thereafter  to  be  the  Beneficial  Owner  of  shares
representing  ten percent (10%) or more of the votes  entitled to be cast by the
Voting Stock,  or who would have so continued but for the  unilateral  action of
the Corporation.

         A "Person" shall mean any corporation,  partnership, association, trust
(other than any trust holding stock of the employees of the Corporation pursuant
to any stock purchase,  ownership or employee benefit plan of the  Corporation),
business entity,  estate or individual or any Affiliate (as hereinafter defined)
of any of the foregoing. An "Affiliate" shall mean any corporation, partnership,
association,  trust,  business  entity,  estate or individual  who,  directly or
indirectly,  through one or more intermediaries,  controls, or is controlled by,
or is under common control with, a Person.  "Control" shall mean the possession,
directly  or  indirectly,  of power to  direct  or cause  the  direction  of the
management  and policies of a Person,  whether  through the  ownership of voting
securities, by contract, or otherwise.

         A Person shall be deemed to be the "Beneficial Owner" of shares if such
Person has the sole or shared power to dispose or direct the disposition of such
shares, or the sole or shared power to vote or direct the voting of such shares,
or the sole or shared  power to acquire such  shares,  including  any such power
which is not immediately  exercisable,  whether such power is direct or indirect
or through any contract, arrangement, understanding,  relationship or otherwise.
A Person  shall  not be  deemed  to be a  Beneficial  Owner of  shares  tendered
pursuant to a tender or exchange  offer made by such Person  until the  tendered
shares are accepted for purchase or exchange. A Person shall not be deemed to be
a Beneficial  Owner of shares as to which such person may exercise  voting power
solely by virtue of a revocable proxy  conferring the right to vote. A member of
a national  securities  exchange shall not be deemed to be a Beneficial Owner of
shares  held  directly by it on behalf of another  person  solely  because  such
member is the record  holder of such shares  and,  pursuant to the rules of such
exchange,  may direct the vote of such shares,  without  instructions,  on other
than contested  matters or matters that may affect  substantially  the rights or
privileges  of the holders of the shares to be voted but is otherwise  precluded
by the rules of such exchange from voting without instructions.

         Notwithstanding any other provisions of these Articles or any provision
of law which might otherwise permit a lesser vote or no vote, but in addition to
any  affirmative  vote of the holders of any  particular  class or series of the
Voting Stock  required by law or these  Articles,  the  affirmative  vote of the
holders of at least eighty percent (80%) of the votes entitled to be cast by the
Voting Stock shall be required to alter, amend or repeal this Article VII.

                                  ARTICLE VIII

                           Control Share Acquisitions

         In the event that any  acquiring  person  (an  "Acquiring  Person")  as
defined in Section  13.1-728.1 of the VSCA,  either (i) fails to comply with the
provisions  of  Section  13.1-728.4  of the  VSCA or (ii)  fails to  obtain  the
approval of the  shareholders of the Corporation at any meeting held pursuant to
Section 13.1-728.5 of the VSCA, then the Corporation shall have authority,  upon
approval by  resolution of the Board of Directors,  to call for  redemption,  at
anytime within sixty (60) days after the last  acquisition of any such shares by
such  Acquiring  Person  or the date of such  meeting,  as the case may be,  and
thereafter  to redeem on such date within such 60-day period as may be specified
in such  resolution  (the  "Redemption  Date") all shares of Voting Stock of the
Corporation  theretofore  acquired by the  Acquiring  Person in a control  share
acquisition  (as  defined  in  Section  13.1-728.1  of the VSCA) and then  owned
beneficially  by such Acquiring  Person,  as such number of shares may be either
(i) shown on any control share acquisition  statement or any statement or report
filed by the Acquiring Person with the Securities and Exchange  Commission under

                                       -5-




the Securities Exchange Act of 1934, as amended, or (ii) otherwise determined by
the  Board  of  Directors.  The  redemption  price  shall be paid in cash on the
Redemption Date against  delivery at the principal  office of the Corporation of
certificates evidencing the shares so redeemed.

         All  determinations  by the Board of  Directors as to (i) the status of
any person as an Acquiring  Person under the VSCA,  (ii) the number of shares of
the  Corporation  owned  by such  Acquiring  Person,  (iii)  the  timeliness  of
compliance by an Acquiring Person within Section 13.1-728.4 of the VSCA, or (iv)
the interpretation of the VSCA or this Article VIII if made in good faith, shall
be conclusive and binding on all persons.

                                   ARTICLE IX

                   Limitation of Liability and Indemnification

          A.      Limitation of Liability.  To the full extent that the VSCA 
permits the limitation or elimination of the liability of directors or officers,
a director or officer of the Corporation  shall not be liable to the Corporation
or its shareholders for any monetary damages.

         B.       Mandatory  Indemnification.   The Corporation shall indemnify
a director or officer of the Corporation who is or was a party to any proceeding
by reason of the fact that he is or was such a director  or officer or is or was
serving at the request of the  Corporation as a director,  officer,  employee or
agent of  another  corporation,  partnership,  joint  venture,  trust,  employee
benefit plan or other profit or nonprofit enterprise against all liabilities and
expenses incurred in the proceeding, except such liabilities and expenses as are
incurred because of his willful  misconduct or knowing violation of the criminal
law.  Unless  a  determination  has  been  made  that   indemnification  is  not
permissible, the Corporation shall make advances and reimbursements for expenses
incurred by a director or officer in a proceeding upon receipt of an undertaking
from  him to  repay  the  same  if it is  ultimately  determined  that he is not
entitled to indemnification.  Such undertaking shall be an unlimited,  unsecured
general  obligation  of the  director or officer  and shall be accepted  without
reference  to his ability to make  repayment.  The Board of  Directors is hereby
empowered, by majority vote of a quorum of disinterested  directors, to contract
in advance to indemnify and advance the expenses of any director or officer.

         C.       Permissive Indemnification.  The Board of Directors is hereby 
empowered, by majority vote of a quorum of disinterested directors, to cause the
Corporation  to  indemnify  or contract in advance to  indemnify  any person not
specified  in  Section  B of  this  Article  IX  who  was or is a  party  to any
proceeding,  by reason of the fact that he is or was an employee or agent of the
Corporation,  or is or was  serving  at the  request  of  the  Corporation  as a
director, officer, employee or agent of another corporation,  partnership, joint
venture,  trust,  employee benefit plan or other profit or nonprofit enterprise,
to  the  same  extent  as  if  such  person  was   specified   as  one  to  whom
indemnification is granted in Section B.

         D.       Insurance. The Corporation may purchase and maintain insurance
to indemnify it against the whole or any portion of the liability  assumed by it
in  accordance  with this  Article IX and may also  procure  insurance,  in such
amounts as the Board of Directors may determine,  on behalf of any person who is
or was a director,  officer, employee or agent of the Corporation,  or is or was
serving at the request of the  Corporation as a director,  officer,  employee or
agent of  another  corporation,  partnership,  joint  venture,  trust,  employee
benefit plan or other profit or  non-profit  enterprise,  against any  liability
asserted against or incurred by such person in any such capacity or arising from
his status as such, whether or not the Corporation would have power to indemnify
him against such liability under the provisions of this Article IX.

         E.       Special Legal Counsel.  In the event there has been a change 
in the composition of a majority of the Board of Directors after the date of the
alleged act or omission with respect to which  indemnification  is claimed,  any
determination as to indemnification  and advancement of expenses with respect to
any claim for  indemnification  made  pursuant  to Section B of this  Article IX
shall be made by special legal counsel agreed upon by the Board of Directors and
the proposed  indemnitee.  If the Board of Directors and the proposed indemnitee

                                       -6-




are unable to agree upon such special legal counsel,  the Board of Directors and
the  proposed  indemnitee  each shall select a nominee,  and the nominees  shall
select such special legal counsel.

         F.       Indemnitee's  Rights.  The provisions of this Article IX shall
be applicable to all actions,  claims, suits or proceedings  commenced after the
adoption hereof,  whether arising from any action taken or failure to act before
or after such adoption. No amendment,  modification or repeal of this Article IX
shall   diminish   the  rights   provided   hereby  or  diminish  the  right  to
indemnification  with respect to any claim, issue or matter in any other pending
or subsequent  proceeding  that is based in any material  respect on any alleged
action or failure to act prior to such amendment, modification or repeal.

         G.       Additional Indemnitees.  Reference herein to directors, 
officers,  employees  or  agents  shall  include  former  directors,   officers,
employees and agents and their respective heirs, executors and administrators.

                                    ARTICLE X

                              Reservation of Rights

         The Corporation  reserves the right to amend,  alter,  change or repeal
any provision contained in these Articles,  and any other provisions  authorized
by the laws of the Commonwealth of Virginia at the time in force may be added or
inserted,  in the manner now or  hereafter  provided  herein or by statute.  All
rights,   preferences  and  privileges  of  whatsoever   nature  conferred  upon
shareholders,  directors or any other persons  whomsoever  by these  Articles in
their present form, or as amended, are granted subject to the rights reserved in
this Article X.
