thereof the following:

                  (a)   whether  the class or series is to have  voting  rights,
full, special or limited,  and whether such class or series is to be entitled to
vote as a separate  class  either  alone or together  with the holders of one or
more other classes or series of stock of the Corporation;

                  (b)   the number of shares to  constitute  the class or series
and the designations thereof;

                  (c)   the preferences and relative, participating, optional or
other  special  rights,   if  any,  and  the   qualifications,   limitations  or
restrictions thereof, if any, with respect to any class or series;

                  (d)   whether the shares of any class or series are redeemable
at the option of the Corporation or the holders thereof or upon the happening of
any specified  event and, if redeemable,  the redemption  price or prices (which
may be payable in the form of cash,  notes,  securities or other property),  and
the time or times at which, and the terms and conditions upon which, such shares
are redeemable and the manner of redemption;

                  (e)   whether  the shares of a class or series are  subject to

redemption of such shares for retirement and, if such retirement or sinking fund
or funds are to be  established,  the annual  amount  thereof  and the terms and
provisions relative to the operation thereof;


                                       2


                  (f)   the  dividend  rate,  whether  dividends  are payable in
cash, stock of the Corporation or other property,  the conditions upon which and
the times when such dividends are payable,  the preference to or the relation to
the  payment of  dividends  payable  on any other  class or classes or series of
stock of the  Corporation,  whether  or not such  dividends  are  cumulative  or
noncumulative  and, if  cumulative,  the date or dates from which such dividends
accumulate;

                  (g)   the  preferences,  if any, and the amounts thereof which
the holders of any class or series  thereof will be entitled to receive upon the
voluntary or involuntary  dissolution of, or upon any distribution of the assets
of, the Corporation;

                  (h)   whether the shares of any class or series, at the option
of the Corporation or the holders thereof or upon the happening of any specified
event, are convertible into or exchangeable for the shares of any other class or
classes  or of any other  series of the same or any other  class or  classes  of
stock,  securities or other property of the Corporation and the conversion price
or prices or ratio or the rate or rates at which such exchange may be made, with
such adjustments, if any, as may be stated and expressed or provided for in such
resolution or resolutions; and

                  (i)   such other special rights and protective provisions with
respect to any class or series as may to the Board of Directors seem advisable.

            3.    Variances  in Classes or Series;  Increases  and  Decreases to
Classes and Series.  The shares of each class or series of the  Preferred  Stock
may vary from the shares of any other  class or series  thereof in any or all of
the foregoing respects. The Board of Directors may increase the number of shares
of the  Preferred  Stock  designated  for any  existing  class  or  series  by a
resolution  adding to such class or series authorized and unissued shares of the
Preferred  Stock not  designated  for any other  class or  series.  The Board of
Directors  may decrease the number of shares of the Preferred  Stock  designated
for any existing class or series by a resolution  subtracting from such class or
series,  and the shares so  subtracted  will  become  authorized,  unissued  and
undesignated shares of the Preferred Stock.

      B.    Provisions Relating to the Common Stock.

            1.    General.  Except as otherwise provided herein, or as otherwise
provided by applicable law, all shares of Common Stock have identical rights and
privileges in every  respect.  Except as  specifically  provided by the Board of
Directors in a resolution  providing for any Preferred Stock, or series thereof,
in no event  will  shares  of  Common  Stock  have  preferences  over  shares of
Preferred  Stock with respect to payment of dividends or  distribution of assets
upon liquidation of the Corporation.

            2.    Voting.  Except as otherwise provided herein, the Common Stock
will be fully  voting  stock  entitled to one vote per share with respect to all
matters to be voted on by the  Corporation's  shareholders.  Except as expressly
required under the Act and except as otherwise provided herein, the Common Stock
will vote as a single  class with  respect to all  matters to be voted on by the
Corporation's shareholders.  Except as otherwise required by law or as otherwise


                                       3


provided by the Board of Directors  with  respect to any  Preferred  Stock,  the
holders of the Common Stock exclusively possess all voting power with respect to
the Corporation.

            3.    Liquidation.  Except as otherwise provided herein, a holder of
the Common Stock will share  ratably with the other holders of Common Stock on a
share-for-share  basis in all  distributions of assets pursuant to any voluntary
or involuntary liquidation, dissolution or winding-up of the Corporation.

      C.    General.

            1.    Consideration.  Subject to the  foregoing  provisions  of this
Certificate of Incorporation,  the Corporation may issue shares of its Preferred
Stock and Common Stock from time to time for such  consideration  (not less than
the par  value  thereof)  as may be fixed by the  Board of  Directors,  which is
expressly authorized to fix the same in its absolute and uncontrolled discretion
subject  to  the   foregoing   conditions.   Shares  so  issued  for  which  the
consideration has been paid or delivered to the Corporation will be deemed fully
paid stock and will not be liable to any further call or assessment thereon, and
the  holders of such  shares  will not be liable  for any  further  payments  in
respect of such shares.

            2.    Rights and  Options.  The  Corporation  has the  authority  to
create and issue rights,  warrants and options  entitling the holders thereof to
purchase  shares of the  Corporation's  capital  stock of any class or series or
other securities of the Corporation,  and such rights, warrants and options will
be evidenced by instrument(s)  approved by the Board of Directors.  The Board of
Directors is empowered to set the exercise price,  duration,  times for exercise
and other terms of such rights, warrants or options; provided, however, that the
consideration to be received for any shares of capital stock subject thereto may
not be less than the par value thereof.

                      ARTICLE FIVE - BUSINESS COMBINATIONS

      The  following   paragraphs  (A)  through  (D)  apply  during  the  period
commencing upon the filing of this Certificate of Incorporation  and terminating
upon the consummation of any Business Combination (as defined below) and may not
be amended during the Target  Business  Acquisition  Period (as defined  below).
"Business  Combination"  means the  acquisition by the  Corporation,  whether by
merger, capital stock exchange, asset or stock acquisition or other similar type
of  transaction,  of an  operating  business  in the  petroleum  or oil  and gas
industries  ("Target  Business"),  and  specifically  includes the  exploration,
development,  extraction,  production,  refining, storage, transportation and/or
marketing of petroleum,  petroleum  products and natural gas.  "Target  Business
Acquisition  Period" means the period from the effectiveness of the registration
statement  filed in connection  with the  Corporation's  initial public offering
("IPO") up to and including  the first to occur of: (i) a Business  Combination;
or (ii) the Termination Date (as defined below).


                                       4


      A.    Shareholder Approval.

      Prior to the  consummation  of any Business  Combination,  the Corporation
must  submit  such  Business   Combination  to  its  stockholders  for  approval
regardless of whether the Business Combination is of a type which normally would
require such stockholder approval under the Act. In the event that a majority of
the IPO Shares (as defined  below)  cast at the meeting to approve the  Business
Combination  are  voted  for the  approval  of such  Business  Combination,  the
Corporation will be authorized to consummate the Business Combination;  provided
that the Corporation may not consummate any Business  Combination if the holders
of 20% or more of the IPO Shares exercise their  conversion  rights described in
paragraph B below.

      B.    Redemption Rights.

      In the event that a Business  Combination  is approved in accordance  with
paragraph A above and is consummated by the Corporation,  any stockholder of the
Corporation  holding shares of Common Stock issued in the IPO ("IPO Shares") who
voted against the Business  Combination may,  contemporaneously  with such vote,
demand that the  Corporation  convert his IPO Shares into cash.  If so demanded,
the Corporation will,  promptly after consummation of the Business  Combination,
convert  such  shares  into cash at a per share  conversion  price  equal to the
quotient  determined  by  dividing  (i) the amount in the Trust Fund (as defined
below),  inclusive of any interest or other earnings  thereon,  calculated as of
two business days prior to the consummation of the Business Combination, by (ii)
the total number of IPO Shares. "Trust Fund" means the trust account established
by the  Corporation  at the  consummation  of its IPO and into  which a  certain
amount of the net proceeds of the IPO is deposited.

      C.    Failure to Consummate a Business Combination.

      In  the  event  that  the  Corporation  does  not  consummate  a  Business
Combination by the later of (i) 18 months after the  consummation  of the IPO or
(ii) 24 months  after the  consummation  of the IPO in the event  that  either a
letter of intent,  an  agreement  in  principle  or a  definitive  agreement  to
complete a Business Combination was executed but was not consummated within such
18-month period (such later date being referred to as the  "Termination  Date"),
the officers of the Corporation  will take all action  necessary to dissolve and
liquidate the Corporation as soon as reasonably  practicable.  In the event that
the Corporation is so dissolved and  liquidated,  only the holders of IPO Shares
are entitled to receive  liquidating  distributions and the Corporation will pay
no liquidating  distributions  with respect to any other shares of capital stock
of the Corporation.

      D.    Trust Fund.

      A holder of IPO Shares will be entitled to receive  distributions from the
Trust Fund only in the event of a liquidation of the Corporation or in the event
he demands  conversion of his shares in accordance with paragraph B above. In no
other  circumstances  will a holder of IPO Shares  have any right or interest of
any kind in or to the Trust Fund.


                                       5


                         ARTICLE SIX - PREEMPTIVE RIGHTS

      The shareholders of the Corporation  have no preemptive  rights to acquire
unissued shares of the Corporation, or securities of the Corporation convertible
into or  carrying  a right to  subscribe  to or  acquire  shares of stock of the
Corporation.

                          ARTICLE SEVEN - INCORPORATOR

      The name and mailing address of the incorporator of the Corporation are as
follows:

Douglas D. Hommert
8235 Forsyth Avenue, 4th Floor
Clayton, Missouri 63105

                       ARTICLE EIGHT - BOARD OF DIRECTORS

      The following  provisions  are inserted for the management of the business
and  for  the  conduct  of the  affairs  of the  Corporation,  and  for  further
definition,  limitation and regulation of the powers of the  Corporation  and of
its directors and stockholders.

      A.    Number of Directors.

      The number of directors  initially to constitute the Board of Directors is
three.  Thereafter,  the number of directors of the  Corporation may be changed:
(i) by amendment to this Certificate of  Incorporation;  or (ii) as set forth in
the Corporation's bylaws.

      B.    Classes of Directors.

      The Board of Directors  are divided into three  classes:  Class A, Class B
and Class C. The number of  directors  in each  class are to be nearly  equal as
possible.  At  the  first  election  of  directors  by  the  incorporator,   the
incorporator  will  elect  a  Class  C  director  for a  term  expiring  at  the
Corporation's  third  annual  meeting  of the  Corporation's  stockholders  (the
"Annual  Meeting  of  Stockholders").  The Class C  director  will then  appoint
additional Class A, Class B and Class C directors as necessary. The directors in
Class A will be  elected  for a term  expiring  at the first  Annual  Meeting of
Stockholders,  the  directors in Class B will be elected for a term  expiring at
the second Annual Meeting of  Stockholders  and the directors in Class C will be
elected  for a term  expiring  at the  third  Annual  Meeting  of  Stockholders.
Commencing  at the first  Annual  Meeting of  Stockholders,  and at each  Annual
Meeting of Stockholders thereafter, directors elected to succeed those directors
whose  terms  expire will be elected for a term of office to expire at the third
succeeding  Annual Meeting of Stockholders  after their election.  Except as the
Act  may  otherwise   require,   in  the  interim  between  Annual  Meetings  of
Stockholders or special meetings of the  Corporation's  stockholders  called for
the election of directors  and/or the removal of one or more  directors  and the
filling of any vacancy in that connection,  newly created  directorships and any
vacancies in the Board of Directors, including unfilled vacancies resulting from
the removal of directors  for cause,  may be filled by the vote of a majority of


                                       6


the remaining directors then in office,  although less than a quorum (as defined
in the Corporation's  bylaws), or by the sole remaining director.  All directors
hold office until the expiration of their  respective  terms of office and until
their  successors have been elected and qualified.  A director elected to fill a
vacancy  resulting from the death,  resignation or removal of a director  serves
for the remainder of the full term of the director  whose death,  resignation or
removal has created  such vacancy and until his  successor  has been elected and
qualified.

      C.    Ballots Not Required.

      Election  of  directors  need not be by ballot  unless  the  bylaws of the
Corporation so provide.

      D.    Bylaws of the Corporation.

      The Board of  Directors  has the power,  without the assent or vote of the
Corporation's stockholders,  to make, alter, amend, change, add to or repeal the
bylaws of the Corporation as provided in the bylaws of the Corporation.

      E.    Contracts.

      The  directors  in their  discretion  may submit any  contract  or act for
approval or ratification at any Annual Meeting of Stockholders or at any meeting
of the Corporation's stockholders called for the purpose of considering any such
act or  contract,  and any  contract  or act that is approved or ratified by the
vote of the  holders  of a  majority  of the stock of the  Corporation  which is
represented  in person or by proxy at such  meeting and entitled to vote thereat
(provided that a lawful quorum of stockholders be there represented in person or
by  proxy)  is  valid  and  binding  upon  the  Corporation  and  upon  all  the
Corporation's  stockholders  as though it had been approved or ratified by every
stockholder  of the  Corporation,  whether  or not  the  contract  or act  would
otherwise be open to legal  attack  because of  directors'  interests or for any
other reason.

      F.    Additional Powers.

      In  addition  to the powers  and  authorities  hereinbefore  or by statute
expressly  conferred upon them,  the directors are hereby  empowered to exercise
all such powers and do all such acts and things as may be  exercised  or done by
the  Corporation;  subject,  nevertheless,  to the provisions of the statutes of
Delaware,  of this Certificate of  Incorporation  and to any bylaws from time to
time  made by the  stockholders;  provided,  however,  that no bylaw so made may
invalidate  any prior act of the  directors  which would have been valid if such
bylaw had not been made.

                   ARTICLE NINE - DURATION OF THE CORPORATION

      The duration of the Corporation is perpetual.


                                       7


          ARTICLE TEN - INTERESTED DIRECTORS, OFFICERS AND SHAREHOLDERS

      No contract or transaction  between the Corporation and one or more of its
directors,  officers or  shareholders  or between the Corporation and any person
(as used herein, "person" means any other natural person,  corporation,  limited
partnership,  general partnership,  joint venture, association,  company, trust,
joint stock company,  bank, trust company,  land trust, vehicle trust,  business
trust, real estate investment trust, estate, limited liability company,  limited
liability partnership,  limited liability limited partnership,  employee benefit
plan or other organization irrespective of whether it is a legal entity, and any
governmental  authority)  in which  one or more of its  directors,  officers  or
shareholders  are  directors,  officers  or  shareholder,  or  have a  financial
interest, will be void or voidable solely for this reason, or solely because the
director or officer is present at or participates in the meeting of the Board of
Directors (or committee  thereof) which  authorizes the contract or transaction,
or solely because his, her or their votes are counted for such purpose,  if: (i)
the  material  facts as to his or her  relationship  or  interest  and as to the
contract or transaction are disclosed or are known to the Board of Directors (or
the committee  thereof),  and the Board of Directors (or such committee) in good
faith  authorizes  the contract or  transaction  by the  affirmative  votes of a
majority of the disinterested directors, even though the disinterested directors
are less than a quorum; (ii) the material facts as to his or her relationship or
interest and as to the contract or transaction are disclosed or are known to the
shareholders  of the Corporation  entitled to vote thereon,  and the contract or
transaction is specifically approved in good faith by vote of such shareholders;
or (iii) the contract or  transaction  is fair as to the  Corporation  as of the
time it is  authorized,  approved  or  ratified  by the  Board of  Directors,  a
committee  of the Board of  Directors or the  shareholders  of the  Corporation.
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  thereof  which
authorizes the contract or transaction.

                        ARTICLE ELEVEN - INDEMNIFICATION

      A.    Indemnification of Officers and Directors.

      The Corporation will indemnify,  to the fullest extent permitted under the
Act,  any  individual  who  was,  is or is  threatened  to be made a party  to a
proceeding  by reason of the fact that he or she:  (i) is or was a  director  or
officer  of the  Corporation;  or  (ii)  while  a  director  or  officer  of the
Corporation  is or was serving at the request of the  Corporation as a director,
officer,  partner,  venturer,  proprietor,  trustee,  employee, agent or similar
functionary  of another  foreign or  domestic  person.  Such right is a contract
right and,  as such,  runs to the  benefit  of any  director  or officer  who is
elected and accepts the  position of director or officer of the  Corporation  or
elects to continue to serve as a director  or officer of the  Corporation  while
this Article Eleven is in effect. Any repeal or amendment of this Article Eleven
may be  prospective  only and will not limit the rights of any such  director or
officer or the obligations of the Corporation  with respect to any claim arising
from or  related  to the  services  of such  director  or  officer in any of the
foregoing  capacities  prior to any such  repeal or  amendment  to this  Article
Eleven. Such right includes the right to be paid by the Corporation for expenses
incurred in defending any such proceeding in advance of its final disposition to


                                       8


the maximum extent  permitted under the Act. If a claim for  indemnification  or
advancement of expenses  hereunder is not paid in full by the Corporation within
60 days after a written claim has been received by the Corporation, the claimant
may at any time  thereafter  bring suit against the  Corporation  to recover the
unpaid amount of the claim and, if successful in whole or in part,  the claimant
will also be entitled to be paid the expenses of prosecuting such claim. It is a
defense to any such action that such  indemnification or advancement of costs of
defense are not permitted  under the Act, but the burden of proving such defense
is on the  Corporation.  Neither the failure of the  Corporation  (including the
Board  of  Directors,  any  committee  thereof,  independent  legal  counsel  or
shareholders)  to have  made its  determination  prior to  commencement  of such
action  that  indemnification  of, or  advancement  of costs of defense  to, the
claimant is permissible in the circumstances, nor an actual determination by the
Corporation   (including  the  Board  of  Directors,   any  committee   thereof,
independent  legal  counsel  or  shareholders)  that  such   indemnification  or
advancement  is not  permissible,  may be a  defense  to the  action or create a
presumption that such indemnification or advancement is not permissible.  In the
event of the death of any individual having a right of indemnification under the
foregoing  provisions,  such  right  inures to the  benefit of his or her heirs,
executors,  administrators  and personal  representatives.  The rights conferred
above  are not  exclusive  of any  other  right  which  any  person  may have or
hereafter  acquire  under any statute,  bylaw,  resolution  of  shareholders  or
directors, agreement or otherwise.

      B.    Indemnification of Employees and Agents.

         The Corporation may additionally indemnify any employee or agent of the
Corporation to the fullest extent permitted by applicable law.

      C.    Definition of Proceeding.

      As used herein, the term "proceeding"  means any: (i) threatened,  pending
or   completed   action,   suit  or   proceeding,   whether   civil,   criminal,
administrative,  arbitrative or investigative;  (ii) appeal in such action, suit
or  proceeding;  and (iii) inquiry or  investigation  that could lead to such an
action, suit or proceeding.

                     ARTICLE TWELVE - LIABILITY OF DIRECTORS

      A  director  of the  Corporation  will  not be  personally  liable  to the
Corporation  or its  shareholders  for monetary  damages for breach of fiduciary
duty as a director,  except for liability:  (i) for any breach of the director's
duty of  loyalty  to the  Corporation  or its  shareholders;  (ii)  for  acts or
omissions not in good faith or which involve  intentional  misconduct or knowing
violation of law; (iii) for any transaction  from which the director  derived an
improper  personal  benefit;  or (iv)  under  ss.174 of the Act.  Any  repeal or
amendment of this Article Twelve by the  shareholders of the Corporation will be
prospective  only and will not adversely  affect any  limitation on the personal
liability  of a director  of the  Corporation  arising  from an act or  omission
occurring  prior to the time of such  repeal or  amendment.  In  addition to the
circumstances in which a director of the Corporation is not personally liable as
set forth in the foregoing  provisions of this Article  Twelve,  a director will
not be liable to the  Corporation or its  shareholders to such further extent as
permitted by any law  hereinafter  enacted,  including  without  limitation  any
subsequent amendment to the Act.

                  ARTICLE THIRTEEN - COMPROMISE OR ARRANGEMENT

      Whenever a compromise or arrangement is proposed  between the  Corporation
and its creditors or any class of them and/or  between the  Corporation  and its
stockholders  or any class of them, any court of equitable  jurisdiction  within
the  State  of  Delaware  may,  on  the  application  in a  summary  way  of the
Corporation or of any creditor or stockholder  thereof or on the  application of
any receiver or receivers  appointed for the Corporation under ss.291 of Title 8
of the Delaware Code or on the  application of trustees in dissolution or of any
receiver or receivers  appointed for the Corporation  under ss.279 of Title 8 of
the  Delaware  Code,  order a meeting of the  creditors  or class of  creditors,
and/or of the stockholders or class of stockholders of the  Corporation,  as the
case may be, to be summoned in such manner as such court directs.  If a majority
in  number  representing  three-fourths  in value of the  creditors  or class of
creditors,   and/or  of  the  stockholders  or  class  of  stockholders  of  the
Corporation,  as the case may be, agree to any compromise or arrangement  and to
any  reorganization  of the  Corporation as a consequence of such  compromise or
arrangement,  such  compromise or arrangement and such  reorganization  will, if
sanctioned by the court to which such  application  has been made, be binding on
all the creditors or class of creditors, and/or on all the stockholders or class
of  stockholders,  of the  Corporation,  as the  case  may be,  and  also on the
Corporation.

      IN WITNESS  WHEREOF,  the Corporation has caused this Amended and Restated
Certificate of Incorporation  to be signed by Douglas D. Hommert,  its Executive
Vice President and Secretary on August 26, 2005.
