          respective  businesses  requires such qualification  (except where the
          failure to so qualify or be in good standing as a foreign  corporation

          on the  consolidated  financial  position,  stockholders'  or members'

          indenture,  mortgage, deed of trust, loan agreement or other agreement
          or  instrument,  which  violation,  breach or  conflict  would  have a
          material  adverse  effect  on  the  consolidated  financial  position,
          stockholders'  or  members'  equity  (as the case may be),  results of
          operation,  business or prospects of the Company and its subsidiaries,
          taken as a whole, to which the Company or any of its subsidiaries is a
          party or by which the Company or any of its  subsidiaries  is bound or
          to which any of the  property  or assets of the  Company or any of its
          subsidiaries is subject, nor will such actions result in any violation
          of the  provisions  of the charter or by-laws of the Company or any of
          its  subsidiaries  or any statute or any order,  rule or regulation of
          any court or governmental  agency or body having jurisdiction over the
          Company  or any of its  subsidiaries  or any of  their  properties  or
          assets;  and  except  for the  registration  of the  Stock  under  the
          Securities   Act  and  such   consents,   approvals,   authorizations,

          purchase and distribution of the Stock by the Underwriter, no consent,
          approval,  authorization or order of, or filing or registration  with,

     (i)  Except  as  described  in the  Prospectus,  there  are  no  contracts,
          agreements  or  understandings  between  the  Company  and any  person
          granting  such person the right  (other  than  rights  which have been
          waived or  satisfied)  to require the  Company to file a  registration
          statement  under the  Securities Act with respect to any securities of
          the  Company  owned or to be owned by such  person or to  require  the
          Company  to  include  such  securities  in the  securities  registered
          pursuant to the  Registration  Statement  or in any  securities  being
          registered  pursuant to any other registration  statement filed by the
          Company under the Securities Act.

     (j)  Except as set forth in the  Prospectus,  the  Company  has not sold or
          issued  any  shares  of  Common  Stock  during  the  six-month  period
          preceding the date of the Prospectus,  including any sales pursuant to
          Rule 144A under,  or  Regulations D or S of, the  Securities Act other
          than shares issued pursuant to director  compensation plans,  employee
          benefit  plans,  qualified  stock  options  plans  or  other  employee
          compensation  plans or  pursuant  to  outstanding  options,  rights or
          warrants.

     (k)  Neither the Company nor any of its subsidiaries  has sustained,  since
          the date of the latest audited  financial  statements  included in the
          Prospectus,  any material loss or interference  with its business from
          fire,  explosion,  flood or other calamity,  whether or not covered by
          insurance,  or from any labor dispute or court or governmental action,
          order or decree,  otherwise than as set forth or  contemplated  in the
          Prospectus, and, since such date, there has not been any change in the

          the Company's  existing director  compensation  plans,  existing stock
          option plan and issuances of stock under,  and the purchase of Company
          stock for, the Company's  existing  stock  purchase plan) or long-term
          debt of the Company or any of its subsidiaries or any material adverse
          change,  or any development  involving a prospective  material adverse
          change,   in  or  affecting  the   management,   financial   position,
          stockholders'  equity or results of operations,  business or prospects
          of the Company and its subsidiaries,  taken as a whole, otherwise than

          schedules), filed as part of the Registration Statement or included in
          the Prospectus  present fairly the financial  condition and results of
          operations of the entities purported to be shown thereby, at the dates
          and for the periods  indicated,  and have been  prepared in conformity
          with generally accepted accounting  principles applied on a consistent
          basis throughout the periods involved.

     (m)  Deloitte  &  Touche  L.L.P.,  who  have  certified  certain  financial
          statements of the Company,  whose reports appear in the Prospectus and
          who will deliver the letter  referred to in Section  9(g) hereof,  are

          Securities  Act and the  Rules and  Regulations,  during  the  periods
          covered by the financial statements on which they reported.

                                       4


     (n)  DeGolyer and  MacNaughton,  whose reserve  audits or  evaluations  are
          referenced or appear,  as the case may be, in the  Prospectus  and who
          will deliver the letter  referred to in Section 9(h) hereof,  were, as
          of December 31, 2002 and  December  31, 2003,  and are, as of the date
          hereof,  independent  engineers  with  respect to the  Company and its
          subsidiaries.

     (o)  The  Company  and  each  of  its   subsidiaries   has  (1)   generally
          satisfactory  or good and  indefeasible  title to all its interests in
          its oil and gas properties,  title investigations  having been carried
          out by or on behalf of such person in accordance with good practice in
          the oil and gas  industry  in the areas in which such  properties  are
          located,  (2) good and  marketable  title in fee  simple to all of its
          other real property, and (3) good and marketable title to all personal
          property  owned  by it,  in each  case  free and  clear of all  liens,
          encumbrances   and  defects  except  such  as  are  described  in  the
          Prospectus  or such as do not  materially  affect  the  value  of such
          properties  as a whole and do not  materially  interfere  with the use
          made  and  proposed  to be made of such  properties  as a whole by the
          Company and its  subsidiaries;  and all real  properties and buildings
          held under lease by the Company and its  subsidiaries are held by them
          under valid,  subsisting and enforceable  leases, with such exceptions
          as are  not  material  and do not  interfere  with  the use  made  and
          proposed to be made of such properties and buildings as a whole by the
          Company and its subsidiaries.

     (p)  The Company and its  subsidiaries  carry, or are covered by, insurance
          in such  amounts and  covering  such risks as the  Company  reasonably
          believes is adequate  for the conduct of their  respective  businesses
          and the value of their  respective  properties  and is  customary  for
          companies engaged in similar businesses in similar industries.

     (q)  The Company and its subsidiaries own or possess adequate rights to use
          all material patents, patent applications,  trademarks, service marks,
          trade names,  trademark  registrations,  service  mark  registrations,
          copyrights and licenses  necessary for the conduct of their respective
          businesses  and have no reason to  believe  that the  conduct of their
          respective  businesses  will conflict  with, and have not received any
          notice of any claim of conflict with, any such rights of others.

     (r)  Except  as  described  in  the  Prospectus,  there  are  no  legal  or
          governmental  proceedings  pending to which the  Company or any of its
          subsidiaries  is a party or of which  any  property  or  assets of the
          Company or any of its subsidiaries is the subject which, if determined
          adversely  to  the  Company  or  any of  its  subsidiaries,  would  be
          reasonably   expected  to  have  a  material  adverse  effect  on  the
          consolidated  financial  position,  stockholders'  equity,  results of
          operations, business or prospects of the Company and its subsidiaries,
          taken as a whole; and, to the best of the Company's knowledge, no such
          proceedings are threatened or contemplated by governmental authorities
          or threatened by others.

     (s)  The  conditions  for use of Form  S-3,  as set  forth  in the  General
          Instructions thereto, have been satisfied.

                                       5


     (t)  There are no  contracts  or other  documents  which are required to be
          described in the  Prospectus or filed as exhibits to the  Registration
          Statement by the Securities Act or by the Rules and Regulations  which
          have not been  described in the Prospectus or filed as exhibits to the
          Registration   Statement  or  incorporated  therein  by  reference  as
          permitted by the Rules and Regulations.

     (u)  No  relationship,  direct or  indirect,  exists  between  or among the
          Company on the one hand,  and the directors,  officers,  stockholders,
          customers  or  suppliers  of the Company on the other  hand,  which is
          required to be described in the Prospectus which is not so described.

     (v)  No labor disturbance by the employees of the Company exists or, to the
          knowledge  of the  Company,  is  imminent  which  might be  reasonably
          expected  to  have  a  material  adverse  effect  on  the  management,
          consolidated  financial  position,  stockholders'  equity,  results of
          operations, business or prospects of the Company and its subsidiaries,
          taken as a whole.

     (w)  The  Company  is in  compliance  in all  material  respects  with  all
          presently  applicable  provisions  of the Employee  Retirement  Income
          Security  Act of 1974,  as  amended,  including  the  regulations  and
          published interpretations  thereunder ("ERISA"); no "reportable event"
          (as defined in ERISA) has occurred with respect to any "pension  plan"
          (as  defined in ERISA) for which the Company  would have any  material
          liability;  the Company has not  incurred and does not expect to incur
          any  material  liability  under (i) Title IV of ERISA with  respect to
          termination of, or withdrawal from, any "pension plan" or (ii) Section
          412 or  4971  of the  Internal  Revenue  Code  of  1986,  as  amended,
          including the  regulations  and published  interpretations  thereunder
          (the "Code"); and each "pension plan" for which the Company would have
          any material  liability that is intended to be qualified under Section
          401(a) of the Code is so qualified in all  material  respects  and, to
          the best of the Company's knowledge,  nothing has occurred, whether by
          action  or by  failure  to act,  which  would  cause  the loss of such
          qualification.

     (x)  The Company and its  subsidiaries  have filed all  federal,  state and
          local income and  franchise  tax returns  required to be filed through
          the date  hereof or have  filed for  appropriate  extensions  for such
          taxes and have paid all taxes due thereon,  and no tax  deficiency has
          been  determined  adversely to the Company or any of its  subsidiaries
          which  has had (nor does the  Company  have any  knowledge  of any tax
          deficiency which, if determined adversely to the Company or any of its
          subsidiaries,   might   have)  a  material   adverse   effect  on  the
          consolidated  financial  position,  stockholders'  equity,  results of
          operations, business or prospects of the Company and its subsidiaries,
          taken as a whole.

     (y)  Since  the date as of  which  information  is given in the  Prospectus
          through the date hereof,  and except as may  otherwise be disclosed in
          the  Prospectus,  the  Company  has not (i)  except for  exercises  of
          options  since  such  date  under  the  Company's   existing  director
          compensation  plans or existing  stock  option plan and  issuances  of
          stock under the Company's  existing  stock  purchase  plan,  issued or

               law, ordinance,  rule,  regulation,  order,  judgment,  decree or

               as defined in the Investment Company Act of 1940, as amended.

          (ee) Except as  described  in the  Prospectus,  no  subsidiary  of the
               Company is currently  prohibited,  directly or  indirectly,  from
               paying  any  dividends  to the  Company,  from  making  any other

               or assets or to conduct their respective  businesses except where
               the failure to have such Permits would not reasonably be expected
               to have a material adverse effect on the management, consolidated
               financial position,  stockholders' equity, results of operations,
               business or prospects of the Company and its subsidiaries,  taken

               received any notice of proceedings  relating to the revocation or
               modification  of  any  such  Permit  which,   singly  or  in  the
               aggregate,  if the subject of an unfavorable decision,  ruling or
               finding,  would have a material adverse effect on the management,
               consolidated financial position, stockholders' equity, results of
               operations,   business  or  prospects  of  the  Company  and  its
               subsidiaries,  taken  as a  whole;  the  Company  and each of its
               subsidiaries  has  operated  and is  operating  its  business  in
               compliance  with and not in violation  of any of its  obligations
               with  respect to each such  Permit  except  where such  violation
               would not  reasonably  be  expected  to have a  material  adverse
               effect  on  the  management,   consolidated  financial  position,
               stockholders'   equity,   results  of  operations,   business  or
               prospects of the Company and its subsidiaries,  taken as a whole;
               no event has occurred  which allows,  or after notice or lapse of
               time or both would allow,  revocation or  termination of any such
               Permit or result in any  other  impairment  of the  rights of the
               Company or any of its subsidiaries under any such Permit, subject
               in  each  case  to  such   qualification   as  described  in  the
               Prospectus;  and,  except as  described in the  Prospectus,  such
               permits  contain  no  restrictions  that  are  burdensome  to the
               Company or any of its subsidiaries  except for restrictions  that

                                       8


               would not,  singly or in the aggregate,  have a material  adverse
               effect  on  the  management,   consolidated  financial  position,
               stockholders'   equity,   results  of  operations,   business  or
               prospects of the Company and its subsidiaries, taken as a whole.

          (gg) The principal  executive officer and principal  financial officer
               of the  Company  have  made all  certifications  required  by the
               Sarbanes-Oxley   Act  or  any  related   rules  and   regulations
               promulgated by the  Commission,  and the statements  contained in
               any such  certification  are complete  and  correct.  The Company
               maintains  "disclosure  controls and  procedures"  (as defined in
               Rule  13a-14(c)  under the Exchange  Act),  and such controls and
               procedures are designed (i) to ensure that  information  required
               to be  disclosed  by the Company in the reports  that it files or
               submits under the Exchange Act is recorded, processed, summarized
               and   reported,   within  the  time  periods   specified  in  the
               Commission's  rules and forms and (ii) to ensure that information
               required to be  disclosed  by the Company in the reports  that it
               files or  submits  under  the  Exchange  Act is  accumulated  and
               communicated to the Company's management, including its principal
               executive officer and principal financial officer, as appropriate
               to allow timely  decisions  regarding  required  disclosure.  The
               Company  does  not  have  any  material  weaknesses  in  internal
               controls,  and there has been no fraud,  whether or not material,
               that  involves   management   or  other   employees  who  have  a
               significant role in the Company's internal controls.  The Company
               is otherwise in  compliance  in all  material  respects  with all
               applicable effective provisions of the Sarbanes-Oxley Act and the
               rules and regulations  promulgated by the Commission (and intends
               to  comply  with  all  applicable  provisions  that  are  not yet
               effective upon effectiveness).

     Any  certificate  signed by any officer of the Company and delivered to the
Underwriter or counsel for the  Underwriter  in connection  with the offering of
the Stock shall be deemed a  representation  and warranty by the Company,  as to
matters covered thereby, to the Underwriter.

     2.   Representations,    Warranties   and   Agreements   of   the   Selling
          Stockholders.  Each Selling  Stockholder  severally,  and not jointly,

               Stock to be sold by the  Selling  Stockholder  hereunder  on such
               date,  free and clear of all  liens,  encumbrances,  equities  or
               claims;  and upon  delivery of such  shares and payment  therefor
               pursuant  hereto and thereto (and assuming  that the  Underwriter
               acquires  the shares of Stock  without  any notice of any adverse
               claim  (within  the  meaning  of  Section  8-105  of the  Uniform
               Commercial  Code) that has been created by the Underwriter or its
               Affiliates)  good and valid title to such shares,  free and clear

               and performance of this Agreement by the Selling  Stockholder and
               the  consummation by the Selling  Stockholder of the transactions
               contemplated  hereby will not conflict with or result in a breach
               or violation of any of the terms or provisions  of, or constitute
               a default under, any material indenture, mortgage, deed of trust,
               loan

               Stockholder  is a party or by which the  Selling  Stockholder  is
               bound or to which any of the  property  or assets of the  Selling
               Stockholder  is  subject,  nor will  such  actions  result in any
               violation  of  the  provisions  of  the  certificate  of  limited
               partnership   or  the   partnership   agreement  of  the  Selling
               Stockholder,  or any statute or any order,  rule or regulation of
               any court or governmental agency or body having jurisdiction over
               the Selling  Stockholder or the property or assets of the Selling
               Stockholder;  and, except for the registration of the Stock under

               registrations, filings or qualifications as may be required under
               the  Exchange  Act  and  applicable   state  securities  laws  in

               Underwriter, no consent, approval,  authorization or order of, or
               filing  or  registration  with,  any such  court or  governmental
               agency  or  body is  required  for the  execution,  delivery  and
               performance of this Agreement by the Selling  Stockholder and the
               consummation  by the  Selling  Stockholder  of  the  transactions
               contemplated hereby and thereby.

               contain an untrue statement of a material fact or omit to state a
               material fact required to be stated  therein or necessary to make
               the statements  therein not misleading;  provided,  however,  the

               shares of the Stock.

          (e)  The number of shares of Stock  beneficially  owned by the Selling

               contemplated  hereby  shall  be  reasonably  satisfactory  in all
               material respects to counsel for the Underwriter, and the Company
               and the Selling Stockholders shall have furnished to such counsel

          (d)  Jenkens and  Gilchrist,  A Professional  Corporation,  shall have
               furnished to the Underwriter its written  opinion,  as counsel to

               Date,  in  form  and  substance  reasonably  satisfactory  to the
               Underwriter, to the effect that:

               (i)  The  Company  and each of its  subsidiaries  have  been duly
                    incorporated  and are validly  existing as  corporations  or
                    limited  liability  companies,  as the case may be,  in good

                    conduct  of  their  respective   businesses   requires  such
                    qualification,  (other  than where the failure to so qualify
                    or be in good  standing as a foreign  corporation  would not
                    have a material adverse effect on the consolidated financial
                    position,  stockholders'  equity,  results of  operation  or
                    business  of the Company  and its  subsidiaries,  taken as a
                    whole), and have all power and authority necessary to own or

                    the  Prospectus,  and all of the  issued  shares of  capital
                    stock of the Company  have been duly and validly  authorized
                    and issued, are fully paid and non-assessable and conform to
                    the description thereof contained in the Prospectus; and all
                    of the issued shares of capital stock (or the equivalent) of

                    authorized and issued and are fully paid, non-assessable and
                    (except  for any  directors'  qualifying  shares)  are owned
                    directly or indirectly by the Company, free and clear of all
                    liens, encumbrances, equities or claims;

               (iii)The  shares of the Stock  being  delivered  on the  Delivery
                    Date to the Underwriter hereunder have been duly and validly
                    authorized  and  validly  issued  and  are  fully  paid  and
                    non-assessable;

               (iv) Except  as  described  in  the  Prospectus,   there  are  no
                    preemptive  or other rights to subscribe for or to purchase,
                    nor any  restriction  upon the  voting or  transfer  of, any
                    shares of the Common Stock (including the Stock) pursuant to
                    the  Company's  charter or by-laws or any agreement or other
                    instrument  filed  as an  exhibit  to one  of the  Company's
                    periodic reports under the Exchange Act;

               (v)  To the best of such counsel's knowledge,  there are no legal
                    or governmental  proceedings pending to which the Company or
                    any of its  subsidiaries is a party or of which any property
                    or assets of the Company or any of its  subsidiaries  is the

                                       15


                    subject which, if determined adversely to the Company or any
                    of its subsidiaries, might have a material adverse effect on
                    the consolidated  financial position,  stockholders' equity,
                    results of operations,  business or prospects of the Company
                    and its subsidiaries,  taken as a whole; and, to the best of
                    such counsel's knowledge, no such proceedings are threatened
                    or contemplated by governmental authorities or threatened by
                    others;

            (vi)    The Registration  Statement was declared effective under the
                    Securities  Act as of the date and  time  specified  in such
                    counsel's  opinion,   the  Prospectus  was  filed  with  the
                    Commission  pursuant to the  subparagraph  of Rule 424(b) of
                    the Rules and  Regulations  specified in such opinion on the
                    date  specified  therein  and no stop order  suspending  the
                    effectiveness of the Registration  Statement has been issued
                    and, to the  knowledge of such counsel,  no  proceeding  for
                    that purpose is pending or threatened by the Commission;

            (vii)   The  Registration  Statement  and  the  Prospectus  and  any
                    further  amendments  or  supplements  thereto  made  by  the
                    Company prior to the Delivery Date (except for the financial
                    statements and financial  schedules and other  financial and

     In rendering such opinion, such counsel may state that (x) their opinion is
limited to matters governed by the Federal laws of the United States of America,
the laws of the State of Texas and the General  Corporation  Law of the State of
Delaware,  and that such  counsel is not admitted in Delaware and (y) insofar as
the foregoing  opinions  relate to the valid  existence and good standing of the
Company  and  its  subsidiaries,  they  are  based  solely  on  certificates  of
authorities in the states of organization  of the Company and such  subsidiaries
that  such  counsel  received  in  response  to  such  counsel's   requests  for
confirmation  of the  existence  and  good  standing  of the  Company  and  such
subsidiaries in such states, copies of which certificates have been furnished to
you,  and, in rendering  the opinion set forth in opinion (i) above with respect
to the  qualification  and the good  standing  as a foreign  corporation  of the
Company and such  subsidiaries,  such counsel has relied solely on  certificates
such counsel  received from the states  necessary to give such opinion that such
counsel received in response to such counsel's requests for confirmation of such
qualification  and good  standing,  as the case may be, of the  Company and such
subsidiaries in such states, copies of which certificates have been furnished to
you.

     Such  counsel  shall  also  have  furnished  to the  Underwriter  a written
statement, addressed to the Underwriter and dated the Delivery Date, in form and
substance  reasonably  satisfactory to the  Underwriter,  to the effect that (x)

such  counsel  has  acted as  counsel  to the  Company  in  connection  with the
preparation of the  Registration  Statement and (y) based on the  foregoing,  no
facts have come to the attention of such counsel which lead them to believe that
the  Registration  Statement  (except for the financial  statements  and related
schedules and other financial data, and reserve information included therein, as
to which  such  counsel  need  express  no  belief)  as of the  Effective  Date,
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated  therein or necessary in order to make the statements
therein not misleading, or that the Prospectus (except as stated above) contains
any  untrue  statement  of a  material  fact or omits to state a  material  fact
necessary  in  order  to  make  the  statements  therein,  in the  light  of the
circumstances under which they were made, not misleading.  The foregoing opinion
and  statement  may be  qualified by a statement to the effect that such counsel
does not assume any responsibility for the accuracy, completeness or fairness of
the statements contained in the Registration Statement or the Prospectus, except

matters.

          (e)  Cleary,  Gottlieb,  Steen & Hamilton  shall have furnished to the
               Underwriter  its  written  opinion,  as  counsel  to  each of the
               Selling Stockholders,  addressed to the Underwriter and dated the
               Delivery Date, in form and substance  reasonably  satisfactory to
               the Underwriter, to the effect that:

               (i)  Each of the Selling  Stockholders  has been duly formed as a
                    limited  partnership  under  the  Delaware  Revised  Uniform
                    Limited  Partnership Act, 6 Del. Sec. 17-101 et. seq. and is
                    validly  existing and in good standing under the laws of the
                    State of Delaware.

               (ii) Each Selling  Stockholder has the partnership power to enter
                    into  this   Agreement   and  to  perform  its   obligations
                    thereunder;

               (iii)The  execution,  delivery and  performance of this Agreement

                    action  of  each  Selling   Stockholder.   The  Underwriting
                    Agreement  has been  duly  executed  and  delivered  by each
                    Selling Stockholder;

               (iv) The  execution and delivery by each Selling  Stockholder  of
                    this  Agreement  and  the  performance  of  its  obligations
                    hereunder   (a)  do  not  require  any  consent,   approval,
                    authorization,  registration or qualification of or with any
                    governmental  authority  of the United  States of America or
                    the State of New York,  except such as may be required under
                    the Securities  Act of 1933 and the Securities  Exchange Act
                    of  1934  (but  without  expressing  an  opinion  as to  any
                    consent,    approval,    authorization,    registration   or
                    qualification that may be required under state securities or
                    Blue Sky laws),  (b) do not result in a breach or  violation
                    of any of the  terms and  provisions  of,  or  constitute  a
                    default  under,  any of  the  constituent  documents  of the
                    Selling  Stockholder and (c) do not violate the terms of any
                    New York State or United States federal law or regulation of
                    the Delaware  Partnership  Act (but without  expressing  any
                    opinion with  respect to United  States  federal  securities
                    laws or any state securities or Blue Sky laws).

                                       18


               (v)  Assuming the Underwriter  acquires its interest in the Stock
                    to be sold by the Selling  Stockholders  to the  Underwriter
                    without  notice of any adverse  claim (within the meaning of
                    the Uniform Commercial Code as in effect in the State of New
                    York (the "UCC")) and the  Underwriter has paid the purchase
                    price for such Stock and has had such Stock  credited to the
                    securities  account of the  Underwriter  maintained with The
                    Depository  Trust Company,  then the Underwriter will have a
                    securities  entitlement (as defined in Section  8-102(a)(17)
                    of the UCC) to such Stock  purchased by the  Underwriter and
                    no action based on an adverse  claim to such Stock  credited
                    to such  securities  account,  whether framed in conversion,
                    replevin,   constructive  trust,  equitable  lien  or  other
                    theory, may be asserted against the Underwriter.

     In  rendering  such  opinion,  such  counsel  may (x) limit the  opinion in
section  9(e)(iv) above to those  documents  received by counsel set forth in an
exhibit to the opinion (which constituent  documents shall be certified as true,
complete and correct copies by the Selling Stockholders or their affiliates) and
(y) state that its opinion is limited to matters governed by the Federal laws of
the United States of America and the laws of the State of New York, the Delaware
Revised  Uniform  Limited  Partnership  Act and the General  Corporation  Law of
Delaware and that such counsel is not admitted in Delaware.

          (f)  The  Underwriter  shall have  received  from  Andrews  Kurth LLP,
               counsel for the Underwriter,  such opinion or opinions, dated the
               Delivery  Date,  with  respect  to the  issuance  and sale of the
               Stock,  the  Registration  Statement,  the  Prospectus  and other
               related matters as the Underwriter  may reasonably  require,  and
               the Company shall have  furnished to such counsel such  documents
               as they  reasonably  request for the purpose of enabling  them to
               pass upon such matters.

          (g)  At the  Delivery  Date,  the  Underwriter  shall have  received a
               letter  from  Deloitte  &  Touche  LLP,  in  form  and  substance
               satisfactory to the Underwriter, addressed to the Underwriter and
               dated the date hereof (i)  confirming  that they are  independent
               public  accountants  within the meaning of the Securities Act and
               are in compliance  with the applicable  requirements  relating to
               the  qualification  of accountants  under Rule 2-01 of Regulation
               S-X of the Commission,  (ii) stating,  as of the date hereof (or,
               with respect to matters involving  changes or developments  since
               the respective dates as of which specified financial  information
               is given in the Prospectus,  as of a date not more than five days
               prior to the date hereof),  the  conclusions and findings of such
               firm with respect to the financial  information and other matters
               ordinarily   covered  by   accountants'   "comfort   letters"  to

               Underwriter a letter from DeGolyer and  MacNaughton  addressed to
               the   Underwriter  and  dated  the  date  of  the  Delivery  Date

               letter,  that they have no  knowledge  of any fact or event  that
               would cause any change to the  conclusions  and  findings of such
               firm at the time made with respect to the information referred to
               in Section 1(n) hereof.

                                       19



          (i)  The Company shall have furnished to the Underwriter, addressed to
               the Underwriter,  a certificate,  dated the Delivery Date, of its
               chief executive  officer and its chief financial  officer stating
               that:

               (i)  The  representations,   warranties  and  agreements  of  the

               (ii) They have carefully examined the Registration  Statement and
                    the Prospectus and, in their opinion (A) as of the Effective
                    Date,  the  Registration  Statement and  Prospectus  did not
                    include any untrue  statement of a material fact and did not
                    omit to state a material fact required to be stated  therein
                    or necessary to make the statements  therein not misleading,
                    and (B) since the Effective Date no event has occurred which
                    should have been set forth in a  supplement  or amendment to
                    the Registration Statement or the Prospectus.

          (j)  Each  Selling  Stockholder  (or  any  custodian  or one  or  more
               attorneys-in-fact  on behalf of each Selling  Stockholder)  shall
               have  furnished  to  the  Underwriter  on  the  Delivery  Date  a
               certificate, dated the Delivery Date, signed by, or on behalf of,
               the  Selling  Stockholder  (or  any  custodian  or  one  or  more
               attorneys-in-fact)  stating that the representations,  warranties
               and agreements of the Selling  Stockholder  contained  herein are
               true and correct in all material respects as of the Delivery Date
               and that the Selling Stockholder has complied with all agreements
               contained herein to be performed by the Selling Stockholder at or
               prior to the Delivery Date.

          (k)  (i) Neither the  Company nor any of its  subsidiaries  shall have
               sustained  since  the  date  of  the  latest  audited   financial
               statements  included in the Prospectus  any loss or  interference
               with its business from fire, explosion,  flood or other calamity,
               whether or not covered by insurance, or from any labor dispute or
               court or governmental action, order or decree,  otherwise than as
               set forth or  contemplated  in the  Prospectus or (ii) since such
               date there shall not have been any change in the capital stock or
               long-term debt of the Company or any of its  subsidiaries  or any
               change, or any development  involving a prospective change, in or
               affecting the general affairs,  management,  financial  position,
               stockholders'  equity,  prospects or results of operations of the
               Company  and its  subsidiaries,  otherwise  than as set  forth or
               contemplated in the Prospectus,  the effect of which, in any such
               case  described in clause (i) or (ii), is, in the judgment of the
               Underwriter,  so material and adverse as to make it impracticable
               or  inadvisable  to  proceed  with  the  public  offering  or the
               delivery of the Stock being delivered on the Delivery Date on the
               terms and in the manner contemplated in the Prospectus.

               American Stock  Exchange or in the  over-the-counter  market,  or
               trading in any  securities  of the Company on any  exchange or in
               the over-the-counter market, shall have been suspended or minimum

               a declaration of a national emergency or war by the United States
               or (iv) there shall have occurred such a material  adverse change
               in general  economic,  political or financial  conditions (or the
               effect of  international  conditions on the financial  markets in
               the United  States  shall be such) as to make it, in the judgment
               of the Underwriter,  impracticable or inadvisable to proceed with
               the public  offering or delivery of the Stock being  delivered on
               the Delivery Date on the terms and in the manner  contemplated in
               the Prospectus.

          (m)  To the extent  required,  the New York Stock  Exchange shall have
               approved the Stock for listing,  subject only to official  notice
               of issuance.

     All  opinions,  letters,  evidence  and  certificates  mentioned  above  or
elsewhere  in this  Agreement  shall  be  deemed  to be in  compliance  with the
provisions hereof only if they are in form and substance reasonably satisfactory
to counsel for the Underwriter.

     10.  Indemnification and Contribution.

     (a)  The Company shall  indemnify and hold  harmless the  Underwriter,  its
          officers  and  employees  and each  person,  if any,  who controls the
          Underwriter within the meaning of the Securities Act, from and against
          any loss, claim, damage or liability,  joint or several, or any action
          in respect thereof  (including,  but not limited to, any loss,  claim,
          damage, liability or action relating to purchases and sales of Stock),
          to which the Underwriter,  officer, employee or controlling person may
          become subject, under the Securities Act or otherwise, insofar as such
          loss,  claim,  damage,  liability or action arises out of, or is based
          upon,  (i) any untrue  statement  or  alleged  untrue  statement  of a
          material  fact  contained  in  (A)  any  Preliminary  Prospectus,  the
          Registration  Statement  or  the  Prospectus  or in any  amendment  or
          supplement thereto or (B) in any materials or information  provided to
          investors by, or with the approval of, the Company in connection  with
          the  marketing of the offering of the Stock  ("Marketing  Materials"),
          including any roadshow or investor  presentations made to investors by
          the Company (whether in person or  electronically);  (ii) the omission
          or  alleged  omission  to state  in any  Preliminary  Prospectus,  the
          Registration  Statement  or the  Prospectus,  or in any  amendment  or
          supplement  thereto,  or in any Marketing  Materials any material fact
          required  to be stated  therein or  necessary  to make the  statements
          therein  not  misleading;  or (iii) any act or  failure  to act or any
          alleged act or failure to act by the  Underwriter in connection  with,
          or relating in any manner to, the Stock or the  offering  contemplated
          hereby,  and which is  included as part of or referred to in any loss,
          claim,  damage,  liability  or  action  arising  out of or based  upon
          matters covered by clause (i) or (ii) above (provided that the Company
          shall not be liable  under this clause  (iii) to the extent that it is
          determined  in a final  judgment by a court of competent  jurisdiction
          that such loss, claim,  damage,  liability or action resulted directly
          from any such acts or  failures  to act  undertaken  or  omitted to be
          taken by the  Underwriter  through  its gross  negligence  or  willful
          misconduct),  and  shall  reimburse  the  Underwriter  and  each  such
          officer,  employee or controlling  person promptly upon demand for any
          legal  or  other  expenses  reasonably  incurred  by the  Underwriter,

                                       21


          officer,   employee  or   controlling   person  in   connection   with
          investigating  or defending  or  preparing to defend  against any such
          loss,  claim,  damage,  liability  or  action  as  such  expenses  are
          incurred;  provided,  however, that the Company shall not be liable in
          any  such  case to the  extent  that  any such  loss,  claim,  damage,
          liability  or action  arises  out of,  or is based  upon,  any  untrue
          statement or alleged untrue  statement or omission or alleged omission
          made in any Preliminary Prospectus,  the Registration Statement or the
          Prospectus,  or in any such amendment or supplement,  in reliance upon
          and in conformity with written information  concerning the Underwriter
          furnished to the Company  through the  Underwriter  by or on behalf of
          the  Underwriter  specifically  for inclusion  therein which  consists
          solely of information set forth in Section 10(f) hereof;  and provided
          further,  however  that  the  Company  shall  not  be  liable  to  the
          Underwriter  in any such case with respect to any untrue  statement or
          alleged untrue statement or omission or alleged omission of a material
          fact in the Preliminary Prospectus to the extent that the loss, claim,
          damage or  liability  of the  Underwriter  (or the  action in  respect
          thereof)  arises out of a sale by the Underwriter of Stock to a person
          who was not sent or given,  at or prior to the closing of such sale to
          such person, a copy of the Prospectus as then amended or supplemented,
          if the Company had  previously  furnished (or made  available)  copies
          thereof to the  Underwriter  and the statement or omission in question
          contained in the  Preliminary  Prospectus was corrected  therein.  The
          foregoing  indemnity  agreement is in addition to any liability  which
          the Company may otherwise  have to the  Underwriter or to any officer,
          employee or controlling person of the Underwriter.

     (b)  Each Selling Stockholder,  severally and not jointly,  shall indemnify
          and hold harmless the  Underwriter,  its officers and  employees,  and
          each person,  if any, who controls the Underwriter  within the meaning
          of the  Securities  Act, from and against any loss,  claim,  damage or
          liability,  joint  or  several,  or  any  action  in  respect  thereof
          (including,  but not limited to, any loss, claim, damage, liability or
          action  relating  to  purchases  and  sales of  Stock),  to which  the
          Underwriter,  officer,  employee  or  controlling  person  may  become
          subject, under the Securities Act or otherwise,  insofar as such loss,
          claim,  damage,  liability or action  arises out of, or is based upon,
          (1) any untrue  statement  or alleged  untrue  statement of a material
          fact  contained  in  any  Preliminary  Prospectus,   the  Registration
          Statement or the Prospectus or in any amendment or supplement  thereto
          or (2) the  omission or alleged  omission to state in any  Preliminary
          Prospectus,  Registration  Statement  or  the  Prospectus,  or in  any
          amendment or  supplement  thereto,  any material  fact  required to be
          stated  therein  or  necessary  to make  the  statements  therein  not
          misleading,  in the case of subparagraphs  (1) and (2) of this Section
          to the extent,  but only to the extent,  that such untrue statement or
          alleged untrue  statement or omission or alleged  omission was made in
          reliance upon and in conformity with written information  furnished to
          the Company or the Underwriter by such Selling Stockholder directly or
          through such Selling Stockholder's  representatives,  specifically for
          use in the preparation  thereof;  and shall reimburse the Underwriter,
          its officers and  employees and each such  controlling  person for any
          legal or other expenses  reasonably  incurred by the Underwriter,  its
          officers  and  employees  or  controlling  person in  connection  with
          investigating  or defending  or  preparing to defend  against any such
          loss,  claim,  damage,  liability  or  action  as  such  expenses  are

                                       22


          incurred;  provided,  however, that the Selling Stockholders shall not
          be liable in any such case to the extent  that any such  loss,  claim,
          damage,  liability  or action  arises  out of, or is based  upon,  any
          untrue  statement or alleged  untrue  statement or omission or alleged
          omission  made  in  any  Preliminary   Prospectus,   the  Registration
          Statement or the  Prospectus or in any such amendment or supplement in
          reliance upon and in conformity  with written  information  concerning
          the  Underwriter  furnished  to the  Company  by or on  behalf  of the
          Underwriter  specifically for inclusion  therein which consists solely
          of the  information  specified in Section  10(f) hereof and  provided,
          further,  that  with  respect  to  any  Preliminary  Prospectus,   the
          foregoing  indemnity  agreement  shall not inure to the benefit of the
          Underwriter  from whom the person asserting any loss,  claim,  damage,
          liability or expense  purchased  Stock, or any person  controlling the
          Underwriter,  if copies of the Prospectus were timely delivered to the
          Underwriter  pursuant to this  Agreement and a copy of the  Prospectus
          (as then amended or  supplemented  if the Company shall have furnished
          any amendments or supplements  thereto) was not sent or given by or on
          behalf of the  Underwriter  to such  person,  if required by law so to
          have  been   delivered  and  if  the  Prospectus  (as  so  amended  or
          supplemented)  would have cured the defect  giving  rise to such loss,
          claim,  damage,  liability or expense.  However, in no event shall the
          Selling  Stockholder be liable under the provisions of this Section 10
          for any  amount  in  excess of the  total  proceeds  received  by such
          Selling  Stockholder  from  the  sale of the  Stock  by  such  Selling
          Stockholder  (after  deducting  commissions,  but before taxes and any
          other expenses)  pursuant to this Agreement.  The foregoing  indemnity
          agreement  is  in  addition  to  any   liability   which  the  Selling
          Stockholders  may otherwise  have to the  Underwriter  or any officer,
          employee or controlling person of the Underwriter.

     (c)  The  Underwriter  shall  indemnify and hold harmless the Company,  its
          officers and  employees,  each of its directors,  and each person,  if
          any,  who controls  the Company  within the meaning of the  Securities
          Act, and each Selling Stockholder and its officers and employees, each
          of its  directors,  and each person if any,  who  controls the Selling
          Stockholder  within the meaning of the Securities Act from and against
          any loss, claim, damage or liability,  joint or several, or any action
          in respect thereof, to which the Company or any such director, officer
          or controlling person may become subject,  under the Securities Act or
          otherwise,  insofar as such loss, claim,  damage,  liability or action
          arises out of, or is based upon,  (i) any untrue  statement or alleged
          untrue  statement  of a material  fact  contained  in any  Preliminary
          Prospectus,  the  Registration  Statement or the  Prospectus or in any
          amendment  or  supplement  thereto  or (ii) the  omission  or  alleged
          omission  to state in any  Preliminary  Prospectus,  the  Registration
          Statement  or  the  Prospectus,  or in  any  amendment  or  supplement
          thereto,  or in any Marketing  Materials any material fact required to
          be stated  therein or  necessary  to make the  statements  therein not
          misleading,  but in each  case  only to the  extent  that  the  untrue
          statement or alleged untrue  statement or omission or alleged omission
          was made in reliance upon and in conformity  with written  information
          concerning  the  Underwriter  furnished  to the  Company  through  the
          Underwriter  by or on  behalf  of  the  Underwriter  specifically  for
          inclusion  therein,  and shall  reimburse  the  Company,  such Selling
          Stockholder  and any such director,  officer or controlling  person of
          the Company or the Selling Stockholder for any legal or other expenses
          reasonably  incurred by the Company,  such Selling  Stockholder or any
          such  director,  officer or  controlling  person of the Company or the
          Selling  Stockholder in connection with  investigating or defending or
          preparing to defend against any such loss, claim, damage, liability or
          action  as  such  expenses  are  incurred.   The  foregoing  indemnity

                                       23


          agreement is in addition to any liability  which the  Underwriter  may
          otherwise  have to the Company,  such Selling  Stockholder or any such
          director,  officer,  employee or controlling  person of the Company or
          the Selling Stockholder.

     (d)  Promptly after receipt by an  indemnified  party under this Section 10
          of  notice  of any  claim  or the  commencement  of  any  action,  the
          indemnified  party shall,  if a claim in respect thereof is to be made
          against  the  indemnifying  party under this  Section  10,  notify the
          indemnifying party in writing of the claim or the commencement of that
          action; provided, however, that the failure to notify the indemnifying
          party shall not relieve it from any liability  which it may have under
          this Section 10 except to the extent it has been materially prejudiced
          by such failure; and, provided further, that the failure to notify the
          indemnifying  party shall not relieve it from any  liability  which it
          may have to an indemnified party otherwise than under this Section 10.
          If any such claim or action  shall be brought  against an  indemnified
          party,  and it  shall  notify  the  indemnifying  party  thereof,  the
          indemnifying  party shall be entitled to  participate  therein and, to
          the extent that it wishes,  jointly with any other similarly  notified
          indemnifying  party,  to  assume  the  defense  thereof  with  counsel
          reasonably  satisfactory to the indemnified  party.  After notice from
          the  indemnifying  party to the  indemnified  party of its election to
          assume the  defense of such claim or action,  the  indemnifying  party
          shall not be liable to the indemnified party under this Section 10 for
          any legal or other expenses  subsequently  incurred by the indemnified
          party in connection  with the defense  thereof  other than  reasonable
          costs of investigation;  provided, however, that the Underwriter shall
          have the right to employ counsel to represent the  Underwriter and its
          respective  officers,  employees  and  controlling  persons who may be
          subject  to  liability  arising  out of any claim in  respect of which
          indemnity may be sought by the Underwriter  against the Company or any
          Selling  Stockholder  under  this  Section  10 if,  in the  reasonable
          judgment of the  Underwriter,  it is  advisable  for the  Underwriter,
          officers,  employees and controlling persons to be jointly represented
          by separate  counsel,  and in that event the fees and expenses of such
          separate counsel shall be paid by the Company or Selling Stockholders.
          No  indemnifying  party shall (i) without the prior written consent of
          the  indemnified  parties  (which  consent  shall not be  unreasonably
          withheld),  settle  or  compromise  or  consent  to the  entry  of any
          judgment with respect to any pending or threatened claim, action, suit
          or proceeding in respect of which  indemnification or contribution may
          be sought hereunder (whether or not the indemnified parties are actual
          or potential  parties to such claim or action) unless such settlement,
          compromise  or  consent  includes  an  unconditional  release  of each
          indemnified  party  from  all  liability  arising  out of such  claim,
          action,  suit or  proceeding,  or (ii) be liable for any settlement of
          any such action  effected  without its written  consent (which consent
          shall not be unreasonably  withheld),  but if settled with the consent
          of the  indemnifying  party  or if there  be a final  judgment  of the
          plaintiff  in any  such  action,  the  indemnifying  party  agrees  to
          indemnify and hold harmless any indemnified party from and against any
          loss or liability by reason of such settlement or judgment.

     (e)  If the  indemnification  provided for in this Section 10 shall for any
          reason  be  unavailable  to  or   insufficient  to  hold  harmless  an
          indemnified  party under Section  10(a),  10(b) or 10(c) in respect of
          any  loss,  claim,  damage or  liability,  or any  action  in  respect
          thereof,  referred to therein,  then each indemnifying party shall, in
          lieu of indemnifying such indemnified party,  contribute to the amount

                                       24


          paid or  payable by such  indemnified  party as a result of such loss,
          claim, damage or liability,  or action in respect thereof, (i) in such
          proportion as shall be  appropriate  to reflect the relative  benefits
          received by the Company and the Selling  Stockholders  on the one hand
          and the  Underwriter  on the other from the  offering  of the Stock or
          (ii) if the  allocation  provided by clause (i) above is not permitted
          by applicable law, in such proportion as is appropriate to reflect not
          only the  relative  benefits  referred to in clause (i) above but also
          the relative fault of the Company and the Selling  Stockholders on the
          one  hand  and  the  Underwriter  on the  other  with  respect  to the
          statements or omissions which resulted in such loss, claim,  damage or
          liability, or action in respect thereof, as well as any other relevant
          equitable  considerations;  provided, the Selling Stockholders and the
          Underwriter  shall be obligated to contribute under this Section 10(e)
          only with respect to losses, liabilities,  claims, damages or expenses
          arising  out of an untrue  statement  or  omission  or alleged  untrue
          statement or omission of a material  fact made in reliance upon and in
          conformity  with the written  information  furnished to the Company or
          the Underwriter or any Selling Stockholder, as the case may be, by the
          Underwriter  or the  Selling  Stockholders  directly  or through  such
          Selling   Stockholder's   representatives,   as  the   case   may  be,
          specifically for use in the preparation of any Preliminary Prospectus,
          Registration  Statement  or  the  Prospectus  or in any  amendment  or
          supplement thereto.  The relative benefits received by the Company and
          the Selling  Stockholders  on the one hand and the  Underwriter on the
          other with respect to such offering  shall be deemed to be in the same
          proportion  as the total net  proceeds  from the offering of the Stock
          purchased under this Agreement (before deducting expenses) received by
          the  Company and the Selling  Stockholders,  on the one hand,  and the
          total   underwriting   discounts  and  commissions   received  by  the
          Underwriter  with respect to the shares of the Stock  purchased  under
          this  Agreement,  on the other hand,  bear to the total gross proceeds
          from the offering of the shares of the Stock under this Agreement,  in
          each  case  as  set  forth  in the  table  on the  cover  page  of the
          Prospectus.  The relative  fault shall be  determined  by reference to
          whether the untrue or alleged  untrue  statement of a material fact or
          omission  or  alleged  omission  to state a material  fact  relates to
          information  supplied by the Company,  the Selling Stockholders or the
          Underwriter,  the intent of the parties and their relative  knowledge,
          access to  information  and  opportunity  to correct  or prevent  such
          statement or omission.  The Company,  the Selling Stockholders and the
          Underwriter  agree  that  it  would  not  be  just  and  equitable  if
          contributions  pursuant to this Section 10(e) were to be determined by
          pro rata  allocation or by any other method of  allocation  which does
          not take into account the equitable considerations referred to herein.
          The amount paid or payable by an indemnified  party as a result of the
          loss,  claim,  damage or  liability,  or action  in  respect  thereof,
          referred  to above in this  Section  shall be deemed to  include,  for
          purposes of this Section 10(e), any legal or other expenses reasonably
          incurred by such indemnified party in connection with investigating or
          defending any such action or claim.  Notwithstanding the provisions of
          this  Section  10(e),  (i) the  Underwriter  shall not be  required to
          contribute any amount in excess of the amount by which the total price
          at which the Stock  underwritten  by it and  distributed to the public
          was offered to the public  exceeds the amount of any damages which the
          Underwriter  has  otherwise  paid or become liable to pay by reason of
          any untrue or alleged untrue statement or omission or alleged omission
          and (ii) no Selling  Stockholder  shall be required to contribute  any
          amount  in  excess  of the total  proceeds  received  by such  Selling
          Stockholder from the offering of the Stock by such Selling Stockholder

                                       25


          (after  deducting   commissions,   but  before  taxes  and  any  other
          expenses).  No person guilty of fraudulent  misrepresentation  (within
          the meaning of Section 10(f) of the Securities  Act) shall be entitled
          to contribution  from any person who was not guilty of such fraudulent
          misrepresentation.

     (f)  The  Underwriter  confirms  and  the  Company  acknowledges  that  the
          statements  with  respect to the public  offering  of the Stock by the
