of the  Securities  will  be  governed  by  this  Underwriting  Agreement  (this
"Agreement").

     The Company has prepared and filed in conformity  with the  requirements of
the Securities Act of 1933, as amended (the "1933 Act"), and the published rules

amendments  thereof  as may have been  required  to the date of this  Agreement.
Copies of such registration  statement (including all amendments thereof and all
documents  deemed  incorporated  by  reference  therein) and of the related Base
Prospectus have heretofore been delivered by the Company to the Underwriter. The
term "Registration  Statement" as used in this Agreement means such registration

Securities  Exchange  Act of 1934,  as amended  (the





"1934  Act"),  Rule 415 and Rule 434 of the 1933 Act Rules,  or  otherwise,  any
registration  statement  filed  under  Rule 462  of the 1933  Act  Rules as such
registration  statement  may be  amended  from time to time and all  information

Supplement"). The term "Prospectus" means the Base Prospectus and the Prospectus
Supplement.  Unless  otherwise  stated  herein,  any  reference  herein  to  the
Registration  Statement  and the  Prospectus  shall  be  deemed  to refer to and

Form S-3 under the Securities Act, which were filed under the Exchange Act on or
before the date hereof or are so filed  hereafter.  Any reference  herein to the
terms "amend,"  "amendment,"  or "supplement"  with respect to the  Registration
Statement  or the  Prospectus  shall be deemed to refer to and  include any such
document  filed or to be filed  under  the  Exchange  Act  after the date of the
Registration  Statement  or  Prospectus,  as the case may be,  and  deemed to be
incorporated therein by reference.

     The  Company  understands  that the  Underwriter  proposes to make a public
offering of the Securities, as set forth in and pursuant to the Prospectus.  The
Company hereby confirms that the Underwriter and dealers have been authorized to
distribute or cause to be  distributed  each  Prospectus  and are  authorized to
distribute the Prospectus (as from time to time amended or  supplemented  if the
Company furnishes amendments or supplements thereto to the Underwriter).

qualification  is  required,  whether by reason of the  ownership  or leasing of

of the  Company  and its  subsidiaries,  taken as a whole (a  "Material  Adverse
Effect").  Except as disclosed in the Prospectus,  the Company has no obligation

securities of the Company's  subsidiaries have been duly and validly  authorized
and issued,  are fully paid and  non-assessable,  and are owned by the  Company,

condition contained in any indenture, mortgage, loan agreement or note or in any
material contract,  lease or other instrument to which it is a party or by which
it or any of them may be bound, or to which any of the property or assets of the
Company or any of its subsidiaries  may be bound,  except for such defaults that
would not, singly or in the aggregate, reasonably be expected to have a Material
Adverse Effect;  the  consummation of the transactions  contemplated  herein has
been duly  authorized by the Company by all necessary  corporate  action and the
issuance,  sale and delivery of the Securities  and the execution,  delivery and
performance  of  this  Agreement  by the  Company  will  not  conflict  with  or
constitute  a breach  of,  or  default  under,  or  result  in the  creation  or

Company  or  any of  its  subsidiaries  pursuant  to  any  contract,  indenture,

or any of its  subsidiaries  is a party  or by  which  it or any of them  may be
bound,  or to which any of the  property  or assets of the Company or any of its
subsidiaries  is subject,  nor will such action  result in any  violation of the
provisions  of the charter or by-laws of the Company or any of its  subsidiaries
or any applicable  law,  administrative  regulation or  administrative  or court
decree,  except in each case, for such  conflicts,  defaults or violations  that

governmental  agency  or body,  domestic  or  foreign,  now  pending  or, to the
knowledge of the Company, threatened, against or affecting the Company or any of
its  subsidiaries,  which  is  required  to be  disclosed  in  the  Registration
Statement and Prospectus (other than as disclosed therein), or which, considered
singly or in the  aggregate,  may  reasonably  be  expected  to have a  Material
Adverse Effect,  or which may materially or adversely affect the consummation of
this  Agreement;  all pending  legal or  governmental  proceedings  to which the
Company  or any  of  its  subsidiaries  is a  party  or of  which  any of  their
respective  property or assets is the  subject  which are not  described  in the
Registration  Statement and Prospectus,  including  ordinary routine  litigation
incidental to the business, are, considered in the aggregate,  not material; and

unpatentable  proprietary or confidential  information,  systems or procedures),
trademarks,   service  marks  and  trade  names   (collectively,   "intellectual
property")  presently  employed  by them in  connection  with the  business  now
operated by them,  except where failure to own or possess or have the ability to
acquire any such intellectual  property would not reasonably be expected to have
a Material  Adverse Effect.  Neither the Company nor any of its subsidiaries has
received  any notice of  infringement  of or conflict  with  asserted  rights of
others with respect to any of the foregoing  which,  singly or in the aggregate,
if the subject of an unfavorable decision,  ruling or finding,  would reasonably
be expected to result in any Material


                                       5


 Adverse Effect.

     (xv) No  authorization,  approval  or consent of any court or  governmental
authority or agency is necessary in connection  with the sale of the  Securities
hereunder,  except  such as may be  required  under  the 1933  Act or state  and
foreign securities laws, which qualification has been obtained.

     (xvi) Except as otherwise set forth in the  Registration  Statement and the
Prospectus,  the  Company and each of its  subsidiaries  possess  such  material

operated by them, and, except as set forth in the Registration Statement and the
Prospectus,  neither the Company nor any of its  subsidiaries  has  received any
notice of  proceedings  relating to the revocation or  modification  of any such
certificate,  authorization or permit which, singly or in the aggregate,  if the
subject of an  unfavorable  decision,  ruling or finding,  would  reasonably  be
expected to have a Material Adverse Effect.

     (xvii) The  Company and its  subsidiaries  have filed all  Federal,  state,
local and  foreign tax returns  that are  required to be filed  through the date
hereof,  which  returns are true and correct in all material  respects,  or have
received extensions  thereof,  and have paid all taxes shown on such returns and
all  assessments  received by them to the extent that the same are  material and
have  become due.  There are no tax audits or  investigations  pending,  that if
adversely determined would have a Material Adverse Effect; nor, to the knowledge
of the  Company,  are there any material  proposed  additional  tax  assessments
against  the  Company or any of its  subsidiaries.  The  charges,  accruals  and
reserves  on the books of the  Company in respect of any income and  corporation
tax  liability  for any years not finally  determined  are  adequate to meet any
assessments  or  re-assessments  for  additional  income  tax for any  years not
finally determined,  except to the extent of any inadequacy which would not have
a Material Adverse Effect.

reasonable  intervals  and  appropriate  action  is taken  with  respect  to any
differences.

     (xix) There are no holders of  securities  (debt or equity) of the Company,
or holders of rights,  options or warrants to obtain  securities of the Company,
who, by reason of the filing of the  Registration  Statement under the 1933 Act,
have the right to request the Company to register  under the 1933 Act securities
held by them; and the Company has complied in all material  respects with all of
the terms of any of their outstanding  agreements  relating to the rights of any
holder of  securities  to have  securities  registered  under  the  Registration
Statement.  Except as  described  in the  Prospectus,  there are no  outstanding
options,  warrants or other rights calling for the issuance of, and there are no

     (xxi) Except as described in the Prospectus, as of the date hereof, (A) all
royalties, rentals, deposits and other amounts due on the oil and gas properties
of the Company and each of its subsidiaries  have been properly and timely paid,
and no  proceeds  from the sale or  production  attributable  to the oil and gas

     (xxiv)  There  is no  alleged  liability,  or to  the  best  knowledge  and
information of the Company, potential liability (including,  without limitation,
alleged  or  potential  liability  for  investigatory   costs,   cleanup  costs,
governmental  response  costs,  natural  resources  damages,  property  damages,
personal injuries,  or penalties) of the Company or its subsidiaries arising out

violation or alleged  violation of any  Environmental  Law, (X) which alleged or
potential  liability is required to be disclosed in the  Registration  Statement

limitation, any capital or operating expenditures required for clean-up, closure
of properties or compliance with  Environmental  Laws of any permit,  license or
approval,  any related  constraints  on operating  activities  and any potential

     (xxviii) The Company maintains  reasonably  adequate insurance with respect
to its properties and business  against loss or damage of the kinds  customarily
insured against by corporations of established reputation engaged in the same or
similar businesses and similarly situated,  of such types and in such amounts as

written consent of the  Underwriter,  such persons will not sell, offer to sell,
contract to sell, or otherwise dispose of, directly or indirectly, any shares of
Common  Stock,  any  other  equity  security  of the  Company,  or any  security

or supplement  the Prospectus to comply with the 1933 Act or the 1933 Act Rules,

or if for any other  reason it shall be  necessary  to amend or  supplement  the
Prospectus  in order to comply  with the 1933 Act and the 1934 Act,  the Company

Prospectus  will not include an untrue  statement of a material  fact or omit to
state a material  fact  necessary in order to make the  statements  therein,  in
light of the circumstances  existing at the time it is delivered to a purchaser,

such  qualifications  in effect so long as required for the  distribution of the

          (iii) against any and all expense whatsoever,  as incurred (including,
     subject to  Section  6(c)  hereof,  the fees and  disbursements  of counsel
     chosen by the Underwriter), reasonably incurred in investigating, preparing
     or defending against any litigation,  or any investigation or proceeding by
     a  governmental  agency  o body,  commenced  or  threatened,  or any  claim
     whatsoever  based upon any such untrue  statement or omission,  or any such
     alleged untrue  statement or omission,  to the extent that any such expense
     is not paid under (i) or (ii) above;

provided,  however,  that this  indemnity  agreement  shall not apply (A) to any
loss,  liability,  claim,  damage or expense to the  extent  arising  out of any
untrue  statement or omission or alleged  untrue  statement or omission  made in
reliance  upon and in  conformity  with  written  information  furnished  to the
Company by the Underwriter  expressly for use in the  Registration  Statement or
Prospectus and (B) with respect to the Prospectus or any preliminary  prospectus
to the extent that any loss,  liability,  claim,  damage or expense results from
the fact that the Underwriter  sold Securities to a person to whom there was not
sent or given,  at or prior to the written  confirmation of such sale, a copy of
the Prospectus (and any amendment or supplement  thereto) in any case where such
delivery is required by the 1933 Act if the Company previously  furnished copies
thereof to such Underwriter and the loss,  liability,  claim,  damage or expense
results from an untrue statement or omission of a material fact contained in the
Prospectus or any preliminary  prospectus  which was corrected in the Prospectus
(or any amendment or supplement thereto).

     (b) The Underwriter agrees to indemnify and hold harmless the Company,  its
directors,  each of its officers who signed the Registration Statement, and each
person, if any, who controls the Company within the meaning of Section 15 of the
1933  Act  against  any and all  loss,  liability,  claim,  damage  and  expense
described in the  indemnity  contained in  subsection  (a) of this  Section,  as
incurred,  but only with respect to untrue  statements or omissions,  or alleged
untrue  statements  or  omissions,  made in the  Registration  Statement (or any
amendment  thereto) or any  preliminary  prospectus  or the  Prospectus  (or any
amendment or supplement thereto) in reliance upon and in conformity with written
information furnished to the Company by the Underwriter expressly for use in the
Registration Statement (or any amendment thereto) or such preliminary prospectus
or the Prospectus (or any amendment or supplement thereto).

     (c) Each  indemnified  party shall give  notice as  promptly as  reasonably
practicable to each  indemnifying  party of any action  commenced  against it in
respect of which indemnity may be sought hereunder,  but failure to so notify an
indemnifying  party shall not relieve such indemnifying party from any liability
which it may have  otherwise  than on account of this  indemnity  agreement.  An
indemnifying party may participate at its own expense in the defense of any such
action.  In no event  shall the  indemnifying  parties  be  liable  for fees and
expenses  (which fees and expenses shall be reasonable) of more than one counsel
(in  addition  to any local  counsel)  separate  from their own  counsel for all
indemnified parties in connection with any one action or separate but similar or
related  actions  in the  same  jurisdiction  arising  out of the  same  general
allegations or circumstances;  provided,  however,  that if an indemnified party
shall have been


                                       17


advised in writing by counsel selected to represent the indemnified parties that
an actual or potential  conflict of interest exists between the position of that
indemnified  party and  other  indemnified  parties,  the  indemnified  party in
question shall have the right to select  separate  counsel to participate in the
defense of such action on behalf of such indemnified party, and the indemnifying
parties  shall be  responsible  for the  reasonable  fees and  expenses  of such
separate counsel.

     SECTION  7.  Contribution.  In order  to  provide  for  just and  equitable
contribution in circumstances in which the indemnity  agreement  provided for in
Section 6 is for any reason held to be unenforceable by the indemnified  parties
although   applicable  in  accordance  with  its  terms,  the  Company  and  the
Underwriter  shall  contribute to the  aggregate  losses,  liabilities,  claims,
damages and  expenses of the nature  contemplated  by such  indemnity  agreement
incurred by the Company and the  Underwriter,  as incurred,  in such proportions
that  the  Underwriter  is  responsible  for  that  portion  represented  by the
percentage  that the  underwriting  discount  appearing on the cover page of the
Prospectus bears to the initial public offering price appearing  thereon and the
Company is responsible for the balance; provided, however, that no person guilty
of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933
Act) shall be  entitled  to  contribution  from any person who was not guilty of
such fraudulent misrepresentation. For purposes of this Section, each person, if
any, who controls the  Underwriter  within the meaning of Section 15 of the 1933
Act, and each officer and  director of the  Underwriter  and of any such control
person, shall have the same rights to contribution as the Underwriter,  and each
director of the Company, each officer of the Company who signed the Registration
Statement,  and each person, if any, who controls the Company within the meaning
of Section 15 of the 1933 Act shall have the same rights to  contribution as the
Company.

     SECTION 8. Representations,  Warranties and Agreements to Survive Delivery.
All  representations,  warranties and agreements contained in this Agreement and
the Pricing  Agreement,  or contained in certificates of officers of the Company
submitted pursuant hereto,  shall remain operative and in full force and effect,
regardless  of any  investigation  made by or on  behalf of the  Underwriter  or
controlling  person,  or by or on  behalf  of the  Company,  and  shall  survive
delivery of the Securities to the Underwriter.

     SECTION 9. Termination of the Agreement.  (a) The Underwriter may terminate
this  Agreement,  by notice to the  Company,  at any time at or prior to Closing
Time (i) if there  has  been,  since  the date of this  Agreement  or since  the
respective dates as of which information is given in the Registration Statement,
any material adverse change in the condition,  financial or otherwise, or in the
earnings,  business affairs or business prospects of the Company, whether or not
arising in the ordinary  course of  business,  or (ii) if there has occurred any
material  adverse change in the financial  markets in the United States,  or any
new outbreak of hostilities or material  escalation thereof or other calamity or
crisis,  the  effect  of  which is such as to make it,  in the  judgment  of the
Underwriter,  impracticable to market the Securities or to enforce contracts for
the sale of the  Securities,  or (iii) if trading  in the Common  Stock has been
suspended  by the  Commission,  or if  trading  generally  on the  NYSE has been
suspended,  or minimum or maximum prices for trading have been fixed, or maximum
ranges for prices for securities have been required, by either of the NYSE or by
order of the  Commission or any other  governmental  authority,  or if a banking
moratorium has been declared by federal, Texas, New York or Ohio authorities.



                                       18


     (b) If this  Agreement  is  terminated  pursuant  to this  Section  9, such
termination shall be without liability of any party to any other party except as
provided in Section 4.  Notwithstanding any such termination,  the provisions of
Sections 6 and 7 shall remain in effect.

     SECTION 10. Notices. All notices and other  communications  hereunder shall
be in  writing  and  shall be  deemed  to have  been  duly  given if  mailed  or
transmitted  by  any  standard  form  of  telecommunications.   Notices  to  the

President & CEO, telecopy number (817) 665-5005.

                                     Annex I

                                     OPINION

          (i) The  Company  is duly  organized,  validly  existing,  and in good
     standing   under  the  laws  of  the  State  of   Delaware,   and  has  the
     organizational  power and authority to own or lease its  properties  and to
     conduct  its  business  as  described  in the  Prospectus,  and to execute,
     deliver and perform its obligations under the Underwriting Agreement.

          (ii) The Company and each of its  subsidiaries [If Michigan counsel is
     willing to give then this can be deleted,  but  typically  this is given by
     relying on good standing  certificates  in foreign  jurisdictions]  is duly
     qualified to do business and is in good standing in all jurisdictions where
     it is  required  to be so  qualified,  except  where the  failure  to be so
     qualified  would  not  individually  or in the  aggregate  have a  Material
     Adverse Effect.

          (iii) The  authorized  capital  stock of the  Company  conforms in all
     material  respects to the description  thereof contained in the Prospectus.
     All of the shares of issued and  outstanding  capital  stock of the Company
     have  been duly  authorized  and  validly  issued  and are  fully  paid and
     nonassessable.  The Securities  have been duly  authorized for issuance and
     sale to the Underwriter  pursuant to the  Underwriting  Agreement and, when
     issued and  delivered  by the  Company in the  manner  contemplated  by the
     Underwriting   Agreement,   will  be   validly   issued,   fully  paid  and
     nonassessable.  The sale of the Securities by the Company is not subject to
     preemptive rights.

          (iv)  Except as  disclosed  in the  Prospectus,  all of the issued and
     outstanding  shares of  capital  stock (or any  limited  liability  company
     interests,  as the case may be) of the Company's  subsidiaries are owned by
     the  Company,  free  and  clear  of any  security  interest,  claim,  lien,
     encumbrance or adverse interest of any nature. To such counsel's knowledge,
     there are no  outstanding  options,  warrants,  or other  rights to acquire
     capital stock or other equity securities of any subsidiary of the Company.

          (v) The Common Stock conforms to the descriptions thereof contained in
     the Registration Statement and the Prospectus.

          (vi) No consent,  approval,  authorization or other order from, and no
     filing  with  or  notice  to,  any  state  or  Federal   regulatory   body,
     administrative  agency,  or  other  governmental  authority,  and,  to  our
     knowledge,  no  filing  with or  notice  to any  other  person or entity is
     required for the due authorization,  execution, delivery and performance by
     the Company of the Underwriting Agreement.

          (v) The Underwriting Agreement has been duly authorized,  executed and
     delivered by the Company.

          (vi) The Company is not, and after  giving  effect to the offering and
     sale of the  Securities and the  application  of the proceeds  therefrom as
     described in the  Prospectus,  will not be, an  "investment  company" or an
     entity  "controlled" by an "investment  company," as such terms are defined
     in the Investment Company Act of 1940, as amended.



                                       21


          (vii) The  execution  and delivery by the Company of the  Underwriting
     Agreement and the  performance of its  obligations  thereunder will not (A)
     result in the  violation  of any  statute  or  regulation,  or any order or
     decree of any court or governmental  authority  binding upon the Company or
     its  subsidiaries  or their  respective  properties or (B) conflict with or
     result in a breach or  violation of any of the terms or  provisions  of, or
     constitute  a default or result in the  creation of a lien under any of the
     provisions of the Company's or any of its  subsidiaries'  charter or bylaws
     or any  indenture,  mortgage,  deed  of  trust,  loan  agreement  or  other
     agreement that is material to the Company and its  subsidiaries  taken as a
     whole.

          (viii) The Registration Statement and the Prospectus and the documents
     incorporated  by  reference  therein  comply  as to  form  in all  material
     respects  with  the  requirements  of the  1933  Act or the  1934  Act,  as
     applicable, and the applicable rules and regulations thereunder (except for
     the  financial  statements  and  the  notes  thereto,  financial  schedule,
     statistical  information  and other  financial and accounting data included
     therein).

          (ix) The  statements  contained  in the  Prospectus  under the caption
     "Description  of Capital Stock" and Item 15 in part II of the  Registration
     Statement,  insofar  as  they  purport  to  summarize  the  legal  matters,
     documents or  proceedings  referred to therein,  present fair  summaries of
     such matters, documents or proceedings, as the case may be.

          (x) We do not know of any litigation or any  governmental  proceedings
     or investigations,  pending or threatened,  required to be described in the
     Prospectus that are not described as required, or of any contracts or other
     documents  of a character  required  to be  described  in the  Registration
     Statement  or  Prospectus  or to be filed as exhibits  to the  Registration
     Statement that are not described and filed as required.

          (xi)  The  Registration  Statement  has  become  effective  under  the
     Securities  Act of 1933;  any  required  filing  of the  Prospectus  or any
     supplement  thereto pursuant to Rule 424(b) has been made in the manner and
     within the time period required by Rule 424(b);  and, to our knowledge,  no
     stop order suspending the  effectiveness of the Registration  Statement has
     been issued and no  proceedings  for that  purpose  are  pending  before or
     threatened by the Commission.

          We have not  independently  verified and are not passing upon,  and do
     not assume any responsibility  for, the accuracy,  completeness or fairness
     of the information contained in the Registration  Statement and Prospectus.
     Based upon  discussions  with  officers,  directors  and  employees  of the
     Company,  no facts have come to our attention that cause us to believe that
     the  Registration  Statement  (except for the financial  statements and the
     notes  thereto,  financial  schedules,  statistical  information  and other
     financial  accounting data included therein,  as to all of which we express
     no view), at the time it became effective contained any untrue statement of
     a material  fact or omitted to state a material  fact required to be stated
     therein or necessary to make the statements therein not misleading, or that
     the Prospectus (with the foregoing exceptions), at such time or on the date
     hereof  included or includes  any untrue  statement  of a material  fact or
     omitted or omits to state a material  fact  necessary  in order to make the
     statements  therein,  in light of the  circumstances  under which they were
     made, not misleading.

                                       22


                                    Annex II

          (i) MGV Energy Inc. ("MGV") is duly organized,  validly existing,  and
     in good  standing  under the laws of the  Province of Alberta,  and has the
     organizational  power and authority to own or lease its  properties  and to
     conduct its business as described in the Prospectus.

          (ii) MGV is duly  qualified to do business and is in good  standing in
     all jurisdictions where it is required to be so qualified, except where the
     failure to be so qualified would not  individually or in the aggregate have
     a Material Adverse Effect.

          (iii)  Except  for  MGV   exchangeable   shares  referred  to  in  the
     Prospectus,  all of the issued and  outstanding  shares of capital stock of
     MGV have been duly and validly  authorized  and issued,  are fully paid and
     non-assessable  and,  are  owned  by the  Company,  free  and  clear of any
     security  interest,  claim,  lien,  encumbrance or adverse  interest of any
     nature, of which such counsel is aware. To such counsel's knowledge,  there
     are no outstanding  options,  warrants,  or other rights to acquire capital
     stock or other equity securities of MGV.

                                       23


                                    Annex III

          (i) Each of __________  [the  Company's  Michigan  subsidiaries]  (the
     "Michigan  Subsidiaries") is duly organized,  validly existing, and in good
     standing   under  the  laws  of  the  State  of   Michigan,   and  has  the
     organizational  power and authority to own or lease its  properties  and to
     conduct its business as described in the Prospectus.

          (ii)  Each  of the  Michigan  Subsidiaries  is  duly  qualified  to do
     business and is in good standing in all jurisdictions  where it is required
     to be so qualified,  except where the failure to be so qualified  would not
     individually or in the aggregate have a Material Adverse Effect.

          (iii)  Except as disclosed  in the  Prospectus,  all of the issued and
     outstanding  shares of  capital  stock (or any  limited  liability  company
     interests,  as the case may be) of the Michigan Subsidiaries have been duly
     and validly  authorized and issued,  are fully paid and nonassessable  and,
     are owned by the Company,  free and clear of any security interest,  claim,
     lien,  encumbrance  or adverse  interest of any nature.  To such  counsel's
     knowledge,  there are no outstanding options,  warrants, or other rights to
     acquire  capital  stock or other equity  securities  of any of the Michigan
     Subsidiaries.

                                       24
