                                  ARTICLE III

                         REPRESENTATIONS AND WARRANTIES

   Section 3.1. Representations and Warranties of the Company. The Company
represents and warrants to the Purchasers that, except as set forth in the
Company Disclosure Letter:

     (a) Corporate Existence. The Company is a corporation duly organized,
  legally existing and in good standing under the laws of the State of Nevada
  and has all requisite corporate power and authority to own, lease and
  operate its business as now being conducted. No actions or proceedings to
  dissolve the Company are pending. The Company is duly qualified or licensed
  to transact business as a foreign corporation and is in good standing in
  each of the jurisdictions listed in the Company Disclosure Letter (except
  where the failure to be so qualified or in good standing would not have a
  Material Adverse Effect), which are all of the jurisdictions required for
  the conduct of its business, except where the failure to be so qualified or
  licensed or in good standing is not reasonably expected to have a Material
  Adverse Effect.

     (b) Capitalization. The authorized capital stock of the Company is
  55,000,000 shares, consisting of 50,000,000 shares of Common Stock and
  5,000,000 shares of preferred stock, par value $.01 per share (the
  "Preferred Stock"). As of June 30, 1999, (i) 12,819,488 shares of Common
  Stock are issued and outstanding, all of which are validly issued, fully
  paid and nonassessable and free of preemptive rights, (ii) 91,223 shares of
  Common Stock are held in the treasury of the Company, (iii) 1,893,110
  shares of Common Stock are issuable pursuant to outstanding options to
  purchase shares of the Common Stock, (iv) 1,495,096 shares of Common Stock

  5,012,107 shares of Common Stock are issuable upon conversion of the
  Convertible Debentures, (vi) 6,705 shares of Common Stock are issuable
  under existing employee benefit arrangements and (vii) there are no issued
  and outstanding shares of Preferred Stock. Except as set forth above or
  pursuant to existing employee benefit arrangements set forth in the Company
  Disclosure Letter or the transactions contemplated hereby, there are no
  options, warrants, convertible securities, subscriptions, stock
  appreciation rights, phantom stock plans or stock equivalents or other
  rights, agreements, arrangements or commitments (contingent or otherwise)
  of any character issued or authorized by the Company relating to the issued
  or unissued capital stock of the Company or obligating the Company to issue
  or sell any shares of capital stock of, or options, warrants, convertible
  securities, subscriptions or other equity interests in, the Company. All
  shares of the Company's Common Stock subject to issuance as aforesaid, upon
  issuance on the terms and conditions specified in the instruments pursuant
  to which they are issuable, will be duly authorized, validly issued, fully
  paid and nonassessable. Except pursuant to existing employee arrangements
  set forth in the Company Disclosure Letter or the transactions contemplated
  hereby or as otherwise set forth in the Company Disclosure Letter, there
  are no outstanding contractual obligations of

                                       5


  the Company to repurchase, redeem or otherwise acquire any shares of Common
  Stock or to pay any dividend or make any other distribution in respect
  hereof or to provide funds to, or make any investment (in the form of a
  loan, capital contribution or otherwise) in, any Person.

     (c) Corporate Power and Authorization. Except as set forth in the
  following sentence, the Company has the requisite corporate power and
  authority to execute, deliver and perform its obligations under this
  Agreement and, subject to (i) approval of the Charter Amendment and the
  transactions contemplated by this Agreement by the holders of a majority of
  the shares of Common Stock as of the record date for the Special Meeting
  present in person or represented by proxy and (ii) satisfaction of the
  Exchange Offer Condition or satisfaction of the Bankruptcy Condition and
  entry of the Confirmation Order by the Bankruptcy Court, to consummate the
  transactions contemplated hereby. The execution, delivery and performance
  of this Agreement by the Company and the consummation by the Company of the
  transactions contemplated hereby have been duly authorized by the Board of
  Directors of the Company and, except as set forth in the preceding
  sentence, no other corporate proceedings on the part of the Company are
  necessary to authorize this Agreement or issue the Shares. In addition, as
  of the date hereof, the Company has taken all necessary corporate action to
  ensure that (i) the terms and provisions of Article VII of the Company's
  Bylaws shall not be applicable to the transactions contemplated hereunder
  or to any subsequent "Business Combination" (as such term as used in such
  Article VII) between the Company, on the one hand, and any Purchaser or any
  "Related Person" (as such term is defined in the Company's Bylaws) to such
  Purchaser, on the other hand; (ii) the terms and provisions of Sections
  78.411 through 78.444 of the Nevada General Corporation Law ("NGCL") shall
  not be applicable to the transactions contemplated hereunder or to any
  subsequent "Combination" (as such term is defined in Section 78.416 of the
  NGCL) between the Company, on the one hand, and any Purchaser or
  "affiliate" or "associate" (as such terms are defined in Sections 78.412
  and 78.413, respectively, of the NGCL) and (iii) the provisions of the
  Nevada Control Shares Act shall not be applicable to the transactions
  contemplated hereunder.

     (d) Binding Obligation. Subject to the entry of the Confirmation Order
  by the Bankruptcy Court if the Bankruptcy Case shall have been filed and
  assuming that this Agreement constitutes a valid and binding obligation of
  the Purchasers, this Agreement is enforceable against the Company in
  accordance with its terms, except as such enforcement may be limited by (i)
  any applicable bankruptcy, reorganization, insolvency, fraudulent
  conveyance or similar laws generally affecting the enforcement of
  creditors' rights and (ii) general principles of equity, regardless of
  whether such enforcement is sought in a proceeding in equity or at law, and
  except to the extent that enforceability of the indemnification provisions
  may be limited under applicable securities or bankruptcy laws.

     (e) No Violation. Neither the execution and delivery of this Agreement,
  the consummation of the transactions contemplated hereby nor the
  fulfillment by the Company of its obligations hereunder will (i) violate
  any provision of the charter or bylaws of the Company (assuming approval of
  the Charter Amendment by the Company's shareholders at the Special Meeting
  or pursuant to order of the Bankruptcy Court), (ii) except as a result of
  the filing of the Bankruptcy Case, result in a default, give rise to any
  right of termination, cancellation, acceleration or imposition of any
  indebtedness or Lien, or require any consent or approval (other than any
  consent or approval that has previously been obtained or will be obtained
  prior to the Closing and except for consents or approvals that will not
  have a Material Adverse Effect), under the terms of any permits, mortgage,
  indenture, loan or credit agreement, license, lease or instrument or
  obligation to which the Company or any Subsidiary is a party or by which
  the Company or any Subsidiary or any of their respective properties may be
  bound (except where the failure to obtain such consent or approval will not
  have a Material Adverse Effect), or (iii) violate any law, judgment, order,
  writ, injunction, decree, statute, rule or regulation of any Governmental
  Authority applicable to the Company or any subsidiary (except where such
  violation will not have a Material Adverse Effect).

     (f) Consents. All consents, approvals, qualifications, orders or
  authorizations of, or filings with, any Governmental Authority, and all
  consents under any material contracts, agreements or instruments by which
  the Company or any Subsidiary is bound or to which the Company or any
  Subsidiary is subject

                                       6


  (collectively, "Consents and Approvals"), and required in connection with
  the Company's valid execution, delivery, or performance of this Agreement,
  the offer, sale and delivery of the Shares and the consummation of any
  other transactions contemplated on the part of the Company have been
  obtained or made or will be obtained or made on or prior to the Closing
  Date, except for those Consents and Approvals pursuant to the Bankruptcy
  Code and the Exchange Act and other applicable federal and state bankruptcy
  or securities, takeover and blue sky laws, and except where the failure to
  obtain such Consents and Approvals would not have a Material Adverse
  Effect.

     (g) Financial Information.

       (i) The consolidated balance sheet of the Company and its
    Subsidiaries as of December 31, 1998, and the related consolidated
    statements of operations, shareholders' equity and cash flows for the
    12-month period then ended, including in each case the related
    schedules and notes, reported on by KPMG LLP, fairly present, in all
    material respects, the consolidated financial position of the Company
    and its Subsidiaries as at the date thereof and the consolidated
    results of operations and changes in cash flows for such period, in
    accordance with GAAP, subject to any exceptions noted therein.

       (ii) The unaudited consolidated balance sheet of the Company and its
    Subsidiaries as of March 31, 1999, and the related unaudited
    consolidated statements of operations, shareholders' equity and cash
    flows for the three-month period then ended, as included in the
    Company's Quarterly Report on Form 10-Q for the quarterly period ended
    March 31, 1999, copies of which have been previously delivered to the
    Purchaser Representative, present fairly, in all material respects, the
    consolidated financial position of the Company and its Subsidiaries as
    at the date thereof and the consolidated results of operations and
    changes in cash flows for such period in conformity with GAAP, subject
    to any exceptions noted therein.

       (iii) Since March 31, 1999, there has been no Material Adverse
    Change to the consolidated financial position and results of operations
    of the Company and its Subsidiaries.

       (iv) Except as disclosed in the Exchange Act Reports (as defined
    herein) and the financial statements included therein as of the dates
    thereof, there were no material liabilities of the Company and its
    Subsidiaries taken as a whole (contingent or otherwise), that are
    reasonably expected to have a Material Adverse Effect and would be
    required to be reflected in such financial statements in accordance
    with GAAP.

     (h) Legal Proceedings. Except as set forth in the Company Disclosure
  Letter or as disclosed in the Company's Quarterly Report on Form 10-Q for
  the quarter ended March 31, 1999, there are no claims or charges filed
  with, or proceedings or investigations by, any Governmental Authority or
  actions or suits instituted or pending or, to the best of the Company's
  knowledge, threatened against the Company or any of its Subsidiaries, or
  against any property, asset, interest or right of any of them, that might
  reasonably be expected to have a Material Adverse Effect or restrain,
  enjoin or prevent in any material respect the consummation of the
  transactions contemplated by this Agreement.

     (i) Exchange Act Reports. Since January 1, 1997, the Company and each of
  its Subsidiaries have filed all required reports and statements, together
  with all amendments required to be made with respect thereto, that they
  were required to file with the Securities and Exchange Commission
  (collectively, the "Exchange Act Reports") on a timely basis in all
  material respects, including, without limitation, all reports on Form 10-K,
  10-Q and 8-K. As of their respective dates, the Exchange Act Reports
  complied as to form in all material respects with the requirements of the
  Exchange Act and the rules and regulations of the Securities and Exchange
  Commission applicable to such Exchange Act Reports. No Exchange Act Report
  with respect to periods beginning on or after January 1, 1997 contained, at
  the time filed, any information that was false or misleading with respect
  to any material fact or omitted to state any material fact required to be
  stated or necessary in order to make the statements therein, in light of
  the circumstances under which they were made, not misleading.

                                       7


     (j) Information True and Correct. None of the information supplied or to
  be supplied by the Company for inclusion in the documents to be filed by
  the Company with the Securities and Exchange Commission in connection with
  the transactions contemplated hereby (the "SEC Filing Documents") will, in
  the case of the proxy statement/prospectus or Exchange Offer documents,
  when first mailed to the shareholders of the Company and holders of its
  Convertible Debentures, contain any untrue statement of a material fact or
  omit to state any material fact necessary in order to make the statements
  made therein, in light of the circumstances under which such statements are
  made, not misleading, or, in the case of any registration statement, when
  it becomes effective, be false or misleading with respect to any material
  fact, or omit to state any material fact necessary in order to make the
  statements therein, in light of the circumstances under which such
  statements are made, not misleading, or, in the case of the proxy
  statement/prospectus, Exchange Offer documents or any amendment thereof or
  supplement thereto, at the time of the Special Meeting, be false or
  misleading with respect to any material fact or omit to state any material
  fact necessary to correct any statement or remedy any omission in any
  earlier communication with respect to the solicitation of any proxy or
  ballot for the Special Meeting or in connection with the Prepackaged Plan.
  The SEC Filing Documents will comply with the requirements of Section 1126
  of the Bankruptcy Code, to the extent applicable.

     (k) Fees and Commissions. Except for CIBC WM, neither the Company nor
  any of its Subsidiaries has retained any broker, finder or financial
  advisor in connection with the transactions contemplated by this Agreement.

     (l) Subsidiaries.

       (i) The Company Disclosure Letter lists each Subsidiary, the
    jurisdiction of incorporation of each Subsidiary and the authorized and
    outstanding capital stock of each Subsidiary. Each Subsidiary is a
    corporation duly organized, validly existing and in good standing under
    the laws of the jurisdiction of its incorporation, except where the
    failure to be so organized, existing or in good standing would not have
    a Material Adverse Effect. As detailed in the Company Disclosure
    Letter, each Subsidiary is duly qualified or licensed to transact
    business as a foreign corporation and is in good standing in each of
    the jurisdictions in which such qualification or licensing is required
    for the conduct of its business, except where the failure to be so
    qualified or licensed is not reasonably expected to have a Material
    Adverse Effect. No actions or proceedings to dissolve any Subsidiary
    are pending or, to the knowledge of the Company, threatened.

       (ii) All of the outstanding capital stock or other equity interests
    of each Subsidiary are owned directly or indirectly by the Company,
    free and clear of all Liens, except for Liens that would not
    individually or in the aggregate be expected to have a Material Adverse
    Effect. All outstanding shares of capital stock of each Subsidiary have
    been validly issued and are fully paid and nonassessable. No shares of
    capital stock or other equity interests of any Subsidiary are subject
    to, nor have any been issued in violation of, preemptive or similar
    rights.

       (iii) There are (and as of the Closing Date there will be)
    outstanding (A) no shares of capital stock or other voting securities
    of any Subsidiary not owned by the Company, (B) no securities of the
    Company or any Subsidiary convertible into or exchangeable for shares
    of capital stock or other voting securities of any Subsidiary, (C) no
    options or other rights to acquire from the Company or any Subsidiary,
    and no obligation of the Company or any Subsidiary to issue or sell,
    any shares of capital stock or other voting securities of any
    Subsidiary or any securities convertible into or exchangeable for
    capital stock or voting securities of any Subsidiary, and (D) no equity
    equivalents, interests in the ownership or earnings, or other similar
    rights of or with respect to any Subsidiary not owned by the Company.
    There are (and as of the Closing Date there will be) no outstanding
    obligations of the Company or any Subsidiary to repurchase, redeem, or
    otherwise acquire any of the foregoing shares, securities, options,
    equity equivalents, interests or rights of any Subsidiary.

     (m) Shares. The issuance of the Shares in accordance with the terms
  hereof is not subject to any preemptive or similar rights.

                                       8


     (n) Tax Matters. Except as disclosed in the Company Disclosure Letter:

       (i) and except in each case as would not be reasonably expected to
    have a Material Adverse Effect: all Tax Returns have been or will be
    timely filed by the Company and the Subsidiaries when due in accordance
    with all applicable laws; all Taxes shown on such Tax Returns have been
    or will be timely paid when due; such Tax Returns have been properly
    completed in compliance with all applicable laws and regulations and
    accurately reflect the facts regarding the income, expenses,
    properties, business and operations required to be shown thereon; and
    such Tax Returns are not subject to penalties under Section 6662 of the
    Code (or any corresponding provision of state, local or foreign tax
    law);

       (ii) the Company and the Subsidiaries have paid all Taxes required
    to be paid by them in all material respects (whether or not shown on a
    Tax Return) or for which they could be liable and such liability would
    reasonably be expected to have a Material Adverse Effect (provided that
    it shall not be considered a breach of this representation if it is
    ultimately determined that additional Tax payments are due but such
    assessment is based on an adjustment to a return or position, if such
    party has a reasonable basis for the position taken with respect to
    such Taxes), whether to taxing authorities or to other persons under
    Tax allocation agreements or otherwise; and the charges, accruals, and
    reserves for Taxes due, or accrued but not yet due, relating to their
    income, properties, transactions or operations as reflected in the
    financial statements included in the Company's Form 10-K for the fiscal
    year ended December 31, 1998, are adequate in all material respects;

       (iii) there are no agreements or consents currently in effect for
    the extension or waiver of the time (A) to file any Tax Return or (B)
    for assessment or collection of any Taxes relating to the income,
    properties or operations of the Company or the Subsidiaries, nor has
    the Company or a Subsidiary been requested to enter into any such
    agreement or consent; and

       (iv) there are no Liens for Taxes (other than for current Taxes not
    yet due and payable or, if due and payable, to the extent being
    contested in good faith by appropriate proceedings) upon the assets of
    the Company or the Subsidiaries.

     (o) Compliance With Laws. The business of the Company and the
  Subsidiaries as presently conducted by them complies with all applicable
  laws (including, without limitation, applicable laws relating to
  securities, properties, business products and services, manufacturing
  processes, advertising and sales practices, employment practices, terms and
  conditions of employment, wages and hours, and civil rights, but other than
  Applicable Environmental Laws, which are governed solely by Section 3.1(r)
  below), except for violations or failures to comply, if any, that would not
  reasonably be expected to have a Material Adverse Effect. Neither the
  Company nor any Subsidiary is charged or, to the best knowledge of the
  Company, threatened with or under investigation with respect to, any
  violation of any applicable law relating to any aspect of the business of
  the Company or any Subsidiary, except for violations, if any, that would
  not reasonably be expected to have a Material Adverse Effect.

     (p) Permits. The Company and the Subsidiaries hold all Permits necessary
  or required for the conduct of the business of the Company and the
  Subsidiaries as currently conducted, except where the failure to hold such
  Permits would not reasonably be expected to have a Material Adverse Effect.
  Each of such Permits is in full force and effect, the Company or such
  Subsidiary is in compliance with all its obligations with respect thereto,
  and, to the best knowledge of the Company, no event has occurred which
  permits, or with or without the giving of notice or the passage of time or
  both would permit, the revocation or termination of any thereof, except
  where the failure to have or be in compliance with the terms of such
  Permits would not reasonably be expected to have a Material Adverse Effect.
  Except as disclosed in the Company Disclosure Letter, no notice has been
  issued by any Governmental Authority and no proceeding is pending or, to
  the best knowledge of the Company, threatened with respect to any alleged
  failure by the Company or a Subsidiary to have any Permit the absence of
  which would have a Material Adverse Effect.


                                       9


     (q) Agreements.

       (i) All legally binding contractual agreements or obligations
    (collectively, for purposes of this subsection, "agreements") to which
    the Company or any Subsidiary is a party or by which the Company or any
    Subsidiary or any of their respective properties is otherwise bound,
    regardless of amount or subject matter, that are material to the
    business, assets, results of operations, condition (financial or
    otherwise), or prospects of the Company and the Subsidiaries considered
    as a whole are set forth in the Company Disclosure Letter, except for
    agreements relating to the ongoing oil and gas ownership and operations
    of the Company (including, but not limited to, operating agreements,
    leases, joint venture agreements, seismic licenses, contracts for sale
    of oil and gas or production and hedging and financing arrangements
    less than one year in duration).

       (ii) The Company has made available accurate and complete copies of
    the agreements described in subsection (i) above. Each of such
    agreements is a valid and binding agreement of the Company and the
    Subsidiaries that are parties thereto, enforceable against them in
    accordance with its terms.

     (r) Environmental Matters.

       (i) To the best knowledge of the Company, the properties, operations
    and activities of the Company and the Subsidiaries comply with all
    Applicable Environmental Laws, except for noncompliance that would not
    reasonably be expected to have a Material Adverse Effect;

       (ii) To the best knowledge of the Company, the Company and the
    Subsidiaries and the properties, operations and activities of the
    Company and the Subsidiaries are not subject to any existing, pending
    or threatened proceeding under, or to any remedial obligations under,
    any Applicable Environmental Laws that would reasonably be expected to
    have a Material Adverse Effect;

       (iii) To the best knowledge of the Company, all Permits, if any,
    required to be obtained by the Company or any Subsidiary under any
    Applicable Environmental Laws in connection with any aspect of the
    business of the Company or the Subsidiaries, including without
    limitation those relating to the treatment, storage, disposal or
    release of a Hazardous Material, have been duly obtained and are in
    full force and effect, and the Company and the Subsidiaries are in
    compliance with the material terms and conditions of all such Permits,
    except for noncompliance that would not reasonably be expected to have
    a Material Adverse Effect;

       (iv) To the best knowledge of the Company, the Company and the
    Subsidiaries have satisfied and are currently in compliance with all
    financial responsibility requirements applicable to their respective
    operations and imposed by any Governmental Entity under any Applicable
    Environmental Laws, and the Company and the Subsidiaries have not
    received any notice of noncompliance with any such financial
    responsibility requirements, except where such noncompliance or notice
    thereof would not reasonably be expected to have a Material Adverse
    Effect;

       (v) To the best knowledge of the Company, there are no physical or
    environmental conditions existing on any property owned or leased by
    the Company or any Subsidiary or resulting from the Company's or any
    Subsidiary's operations or activities, past or present, at any
    location, that would give rise to any on-site or off-site remedial
    obligations under any Applicable Environmental Laws, other than normal
    and ordinary remedial work associated with plugging and abandoning of
    oil and gas facilities, and except for obligations that, individually
    or in the aggregate, would not reasonably be expected to have a
    Material Adverse Effect; and

       (vi) To the best knowledge of the Company, since the effective date
    of the relative requirements of Applicable Environmental Laws, all
    hazardous materials generated by the Company or any Subsidiary or used
    by them in connection with their activities on their respective
    properties, operations or activities which have been transported off-
    site, have been transported only by carriers authorized under
    Applicable Environmental Laws to transport such materials, and have
    been disposed of only at treatment, storage and disposal facilities
    authorized under Applicable Environmental Laws

                                       10


    to treat, store or dispose of such materials, and, to the best
    knowledge of the Company, such carriers and facilities, at the time of
    such transportation or disposal, were operating in compliance with such
    authorizations, except where such noncompliance would not reasonably be
    expected to have a Material Adverse Effect.

     (s) ERISA.

       (i) Set forth on the Company Disclosure Letter is a list identifying
    each "employee benefit plan," as defined in Section 3(3) of ERISA, (i)
    which is subject to any provision of ERISA, (ii) which is maintained,
    administered, or contributed to by the Company or any affiliate of the
    Company, and (iii) which covers any employee or former employee of the
    Company or any affiliate of the Company or under which the Company or
    any affiliate of the Company has any liability. The Company has made
    available to the Purchaser Representative accurate and complete copies
    of such plans (and, if applicable, the related trust agreements and IRS
    favorable determination letters) and all amendments thereto and written
    interpretations thereof, together with (A) the three most recent annual
    reports (Form 5500 including, if applicable, Schedule B thereto)
    prepared in connection with any such plan and (B) the most recent
    actuarial valuation report prepared in connection with any such plan.
    Such plans are referred to in this Section as the "Employee Plans." For
    purposes of this Section only, an "affiliate" of any person means any
    other person which, together with such person, would be treated as a
    single employer under Section 414 of the Code. The only Employee Plans
    which individually or collectively would constitute an "employee
    pension benefit plan" as defined in Section 3(2) of ERISA are
    identified as such in the Company Disclosure Letter.

       (ii) Except as otherwise identified in the Company Disclosure
    Letter, (A) no Employee Plan constitutes a "multiemployer plan," as
    defined in Section 3(37) of ERISA (for purposes of this subsection, a
    "Multiemployer Plan"), (B) no Employee Plan is maintained in connection
    with any trust described in Section 501(c)(9) of the Code, (C) no
    Employee Plan is subject to Title IV of ERISA or to the minimum funding
    standards of ERISA and the Code, and (D) during the past five years,
    neither the Company nor any of its affiliates have made or been
    required to make contributions to any Multiemployer Plan. There are no
    material accumulated funding deficiencies as defined in Section 412 of
    the Code (whether or not waived) with respect to any Employee Plan. The
    fair market value of the assets held with respect to each Employee Plan
    that is an employee pension benefit plan (as defined in Section 3(2) of
    ERISA) and which is subject to Title IV of ERISA exceeds the
    actuarially determined present value of all benefit liabilities accrued
    under such Employee Plan (whether or not vested) determined using
    reasonable actuarial assumptions. Neither the Company nor any affiliate
    of the Company has incurred any material liability under Title IV of
    ERISA arising in connection with the termination of, or complete or
    partial withdrawal from, any plan covered or previously covered by
    Title IV of ERISA. The Company and all of the affiliates of the Company
    have paid and discharged promptly when due all liabilities and
    obligations arising under ERISA or the Code of a character which if
    unpaid or unperformed might result in the imposition of a Lien against
    any of the assets of the Company or any Subsidiary, except for such
    liabilities and obligations that would not reasonably be expected to
    have a Material Adverse Effect. Nothing done or omitted to be done and
    no transaction or holding of any asset under or in connection with any
    Employee Plan has or will make the Company or any Subsidiary or any
    director or officer of the Company or any Subsidiary subject to any
    liability under Title I of ERISA or liable for any Tax pursuant to
    Section 4975 of the Code that would have a Material Adverse Effect.
    There are no pending or, to the Company's knowledge, threatened claims
    by or on behalf of the Employee Plans, or by any participant therein,
    alleging a breach or breaches of fiduciary duties or violations of
    applicable laws which could result in liability on the part of the
    Company, its officers or directors, or such Employee Plans, under ERISA
    or any other applicable law and there is no basis for any such claim,
    except for liabilities that would not, individually or in the
    aggregate, have a Material Adverse Effect.

       (iii) Except as otherwise identified in the Company Disclosure
    Letter, no Employee Plan is intended to be qualified under Section
    401(a) of the Code. The Company maintains a simplified

                                       11


    employee pension plan which is intended to satisfy the requirements of
    Section 408(k) of the Code (the "Pension Plan"). The Pension Plan and
    each Employee Plan has been maintained in substantial compliance in all
    material respects with its terms and with the requirements prescribed
    by all applicable laws, including but not limited to ERISA and the
    Code, which are applicable to plans such as the Pension Plan, except
    where the failure to so comply would not have a Material Adverse
    Effect.

       (iv) Set forth in the Company Disclosure Letter is a list of each
    currently outstanding employment, severance or other similar contract
    (and all amendments thereto), arrangement or policy and each plan or
    arrangement (written or oral) providing for insurance coverage
    (including any self-insured arrangements), workers' compensation,
    disability benefits, supplemental unemployment benefits, vacation
    benefits, retirement benefits, deferred compensation, profit-sharing,
    bonuses, stock options, stock appreciation rights or other forms of
    incentive compensation or post-retirement insurance, compensation or
    benefits which (A) is not an Employee Plan, (B) is entered into,
    maintained or contributed to, as the case may be, by the Company or any
    affiliate of the Company, and (C) covers any employee or former
    employee of the Company or any affiliate of the Company or under which
    the Company or any affiliate of the Company has any liability. Such
    contracts, plans and arrangements as described in the preceding
    sentence are referred to for purposes of this subsection as the
    "Benefit Arrangements." Each Benefit Arrangement has been maintained in
    substantial compliance with its terms and with the requirements
    prescribed by applicable law, except where the failure to so comply
    would not have a Material Adverse Effect.

       (v) To the Company's knowledge, neither the Company nor any
    affiliate of the Company has performed any act or failed to perform any
    act, and there is no contract, agreement, plan or arrangement covering
    any employee or former employee of the Company or any affiliate of the
    Company, that, individually or collectively, could give rise to the
    payment of any amount that would not be deductible pursuant to the
    terms of Section 162(a)(1) or 280G of the Code or could give rise to
    any penalty or excise Tax pursuant to Section 4980B or 4999 of the
    Code.

     (t) Oil and Gas Properties.

       (i) Each of the Company and the Subsidiaries has good and defensible
    title to, or valid leasehold or other ownership interests or rights in,
    all of its material oil and gas properties, free and clear of all Liens
    other than (i) preferential purchase rights, requirements for consent
    to assignment and other encumbrances of a similar nature; (ii)
    statutory liens not yet delinquent, or if delinquent, that are being
    contested in good faith in the normal course of business; (iii) matters
    disclosed in the Company Disclosure Letter; (iv) encumbrances that do
    not materially detract from the value, or materially interfere with the
    use of, any such property or otherwise materially impair the business
    or operations being conducted thereon; and (v) any matter that a
    reasonable and prudent operator knowledgeable in the oil and gas
    business would not consider a material impairment of the Company's
    title; provided, that no representation or warranty is made with
    respect to any oil, gas or mineral property or interest to which no
    proved oil or gas reserves are attributed.

       (ii) The Company has made available to the Purchaser Representative
    a copy of each of the reserve reports (the "Reserve Report") dated as
    of January 1, 1999, prepared by the independent reserve engineers as
    described in the Company's Annual Report on Form 10-K for the fiscal
    year ended December  31, 1998 (collectively, the "Reserve Engineers"),
    relating to the oil and gas reserves of the Company and the
    Subsidiaries. The factual information underlying the estimates of the
    reserves of the Company and the Subsidiaries, which was supplied by the
    Company to the Reserve Engineers for the purpose of preparing the
    Reserve Report, including, without limitation, production, volumes,
    sales prices for production, contractual pricing provisions under oil
    or gas sales or marketing contracts under hedging arrangements, costs
    of operations and development, and working interest and net revenue
    information relating to the Company's and the Subsidiaries' ownership
    interests in properties, was true and correct in all material respects
    on the date that such information was so provided; the estimates of
    future capital expenditures and other future exploration and
    development costs supplied to the Reserve Engineers by the Company were
    prepared in good faith

                                       12


    and with a reasonable basis; and other than normal production of the
    reserves, the disposition of interests in oil and gas properties
    described in the Company Disclosure Letter or otherwise permitted in
    this Agreement and intervening oil and gas price fluctuations, the
    Company is not, as of the date hereof, and as of the Closing Date will
    not be, aware of any facts or circumstances that should reasonably
    cause the Company to conclude that the Reserve Report is incorrect in
    any material respect that would result in a Material Adverse Effect.

   Section 3.2. Representations and Warranties of the Purchasers. Each
Purchaser, only with respect to such Purchaser, represents and warrants to the
Company that:

     (a) Purchase for Investment.

       (i) Such Purchaser is acquiring the Shares for its own account and
    not with a view to the public resale or distribution of all or any part
    thereof in any transaction which would constitute a "distribution"
    within the meaning of the Securities Act. Such Purchaser acknowledges
    that it does not intend and is not permitted to assign its rights under
    this Agreement to any third party prior to the Closing.

       (ii) Such Purchaser acknowledges that the Shares have not been and
    will not be registered under the Securities Act, except pursuant to the
    Registration Rights Agreement, the form of which is attached hereto as
    Exhibit B, to be entered into by the Company and the Purchasers at the
    Closing.

       (iii) Such Purchaser is an "accredited investor" within the meaning
    of Rule 501 under Regulation D promulgated under the Securities Act, is
    experienced in evaluating investments in companies such as the Company,
    has such knowledge and experience in financial and business matters as
    to be capable of evaluating the merits and risks of its investment and
    has the ability to bear the entire economic risk of its investment in
    the Company. Such Purchaser acknowledges and understands the distressed
    financial condition of the Company, and that such condition may
    deteriorate significantly between the date hereof and the Closing Date.
    Such Purchaser has made its own evaluation of its investment in the
    Common Stock, based upon such information as is available to it and
    without reliance upon the Company or any other person or entity, and
    such Purchaser agrees that neither the Company nor any other Person has
    any obligation to furnish any additional information to such Purchaser
    except as expressly set forth herein.

       (iv) Such Purchaser is eligible to own stock in a corporation
    holding oil and gas leases on federal lands, including offshore areas,
    under U.S. federal laws or regulations in effect from time to time.

       (v) Such Purchaser acknowledges that the Shares may not be sold,
    transferred, pledged, hypothecated or otherwise disposed of without
    registration under the Securities Act or an exemption therefrom and
    that, in the absence of an effective registration statement covering
    the Shares or an available exemption from registration under the
    Securities Act, such shares must be held indefinitely.

       (vi) Such Purchaser understands and agrees that certificates
    representing the Shares shall bear legends in substantially the
    following form:

      "THE SECURITIES REPRESENTED HEREBY HAVE BEEN ACQUIRED FOR INVESTMENT
      AND MAY NOT BE SOLD OR OFFERED FOR SALE OR OTHERWISE TRANSFERRED,
      EXCEPT PURSUANT TO (i) AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
      SECURITIES ACT OR (ii) AN APPLICABLE EXEMPTION FROM REGISTRATION
      UNDER THE SECURITIES ACT. ANY SALE PURSUANT TO CLAUSE (ii) OF THE
      PRECEDING SENTENCE MUST BE ACCOMPANIED BY AN OPINION OF COUNSEL
      REASONABLY SATISFACTORY TO THE COMPANY TO THE EFFECT THAT SUCH
      EXEMPTION FROM REGISTRATION IS AVAILABLE IN CONNECTION WITH SUCH
      SALE."

                                       13


     (b) Power and Authorization. Such Purchaser has all requisite power and
  authority to execute, deliver and perform its obligations under this
  Agreement and to consummate the transactions contemplated hereby. The
  execution, delivery and performance of this Agreement by such Purchaser and
  the consummation by such Purchaser of the transactions contemplated hereby
  have been duly authorized in accordance with the governing documents of
  such Purchaser, and all action on such Purchaser's part requisite for the
  purchase of the Shares and for the due execution, delivery and performance
  of this Agreement has been taken.

     (c) Binding Obligation. Assuming that this Agreement constitutes a valid
  and binding obligation of the Company, this Agreement is enforceable
  against such Purchaser in accordance with its terms, except as such
  enforcement may be limited by (i) any applicable bankruptcy,
  reorganization, insolvency, fraudulent conveyance or similar laws generally
  affecting the enforcement of creditors' rights and (ii) general principles
  of equity, regardless of whether such enforcement is sought in a proceeding
  in equity or at law, and except to the extent that enforceability of the
  indemnification provisions may be limited under applicable securities or
  bankruptcy laws.

     (d) No Violation. Neither the execution and delivery of this Agreement,
  the consummation of the transactions contemplated hereby nor the
  fulfillment by such Purchaser of its obligations hereunder will (a) violate
  any provision of the organizational documents of such Purchaser, (b) result
  in a default, give rise to any right of termination, cancellation,
  acceleration or imposition of any indebtedness or Lien, or require any
  consent or approval (other than any consent or approval that has previously
  been obtained or will be obtained prior to the Closing and except for
  consents or approvals that will not have a material adverse effect on this
  Agreement or the transactions contemplated hereby), under the terms of any
  permits, mortgage, indenture, loan or credit agreement, license, lease or
  instrument or obligation to which such Purchaser is a party or by which
  such Purchaser may be bound (except where the failure to obtain such
  consent or approval will not have a material adverse effect on this
  Agreement or the transactions contemplated hereby), or (c) violate any law,
  judgment, order, writ, injunction, decree, statute, rule, or regulation of
  any Governmental Authority applicable to such Purchaser (except where such
  violation will not have a material adverse effect on this Agreement or the
  transactions contemplated hereby).

     (e) Consents. All consents, approvals, qualifications, orders, or
  authorizations of, or filings with, any Governmental Authority, and all
  consents under any material contracts, agreements, or instruments by which
  such Purchaser is bound or to which it is subject, and required in
  connection with such Purchaser's valid execution, delivery, or performance
  of this Agreement and the purchase of the Shares and the consummation of
  any other transaction contemplated on the part of such Purchaser have been
  obtained or made.

     (f) Legal Proceedings. There are no claims or charges filed with, or
  proceedings or investigations by, any Governmental Authority or actions or
  suits instituted or pending or, to the best of such Purchaser's knowledge,
  threatened against such Purchaser or any of its affiliates, or against any
  property, asset, interest or right of any of them, that might reasonably be
  expected to have a material adverse effect on such Purchaser or restrain,
  enjoin or prevent in any material respect the consummation of the
  transactions contemplated by this Agreement.

     (g) Information True and Correct. None of the information supplied or to
  be supplied by such Purchaser for inclusion in the SEC Filing Documents
  will, in the case of the proxy statement/prospectus or Exchange Offer
  documents, when first mailed to the shareholders of the Company and holders
  of its Convertible Debentures, contain any untrue statement of a material
  fact or omit to state any material fact necessary in order to make the
  statements made therein, in light of the circumstances under which such
  statements are made, not misleading, or, in the case of any registration
  statement, when it becomes effective, be false or misleading with respect
  to any material fact, or omit to state any material fact necessary in order
  to make the statements therein not misleading, or, in the case of the proxy
  statement/prospectus or Exchange Offer documents, or any amendment thereof
  or supplement thereto, at the time of the Special Meeting, be false or
  misleading with respect to any material fact or omit to state any material
  fact necessary to correct any statement or remedy any omission in any
  earlier communication

                                       14


  with respect to the solicitation of any proxy or ballot for the Special
  Meeting or in connection with the Prepackaged Plan.

     (h) Fees and Commissions. Except for the commitment fee described in
  Section 9.1 hereof, there are no fees payable to any broker, finder or
  financial advisor retained by such Purchaser or any of its affiliates or
  associates in connection with the transactions contemplated by this
  Agreement.

     (i) Sufficient Funds. Such Purchaser has sufficient funds to acquire all
  of the Shares to be purchased by it hereunder, and has no reason to believe
  that such funds will not be available to purchase such Shares at the
  Closing.

     (j) Share Ownership. Except as set forth in the Purchaser Disclosure
  Letter and in connection with the transactions contemplated by this
  Agreement, to the best knowledge of each Purchaser, neither such Purchaser
  nor any of its affiliates (including EnCap Investments L.L.C. and its
  executive officers) or associates beneficially owns any shares of the
  Common Stock or any other securities of the Company.

     (k) Purchaser Representative. The Purchase Representative has full power
  and authority to act on behalf of the Purchasers and to receive a
  commitment fee pursuant to Section 9.1 hereof, which representation and
  receipt of payment will not violate any law, statute, rule, regulation or
  governing document of any Purchaser or require any further consents or
  approvals.

                                   ARTICLE IV

                   COVENANTS RELATING TO CONDUCT OF BUSINESS

   Section 4.1. Prudent Operations. Except as otherwise contemplated in this
Agreement or as set forth in the Company Disclosure Letter, and subject to the
fiduciary duties of the Company's directors under applicable law, from the date
of this Agreement to the Closing Date (except for transactions to which any
Purchaser is a party or as otherwise contemplated by the terms of this
Agreement), (i) prior to the filing of the Bankruptcy Case, if any, the Company
shall, and shall cause its Subsidiaries to, operate their businesses consistent
with prudent industry practices taking into account the Company's financial
condition; and (ii) after the Bankruptcy Case has been filed, the Company shall
operate its business and the business of its Subsidiaries in all material
respects in compliance with the Bankruptcy Code and any orders entered by the
Bankruptcy Court in the Bankruptcy Case, and shall use commercially reasonable

businesses consistent with prudent industry practices taking into account the
Company's financial condition. To the extent consistent with the foregoing, the
Company shall use commercially reasonable efforts to preserve intact its
current officers and employees and preserve its relationships with customers,
suppliers, licensors, licensees, distributors and others having business
dealings with it, in each case consistent with prudent industry practices
taking into account the Company's financial condition. Without limiting the
generality of the foregoing, and except as otherwise contemplated by this
Agreement or referred to in the Company Disclosure Letter, pursuant to the
transactions contemplated hereby and any related agreements or as may be
approved by the Purchaser Representative, the Company shall not, and shall not
permit any of its Subsidiaries to:

     (a) (i) declare, set aside or pay any dividends on, or make any other

                                       16


   Section 4.2. Changes in Employment Arrangements. Except as set forth in the
Company Disclosure Letter, neither the Company nor any of its Subsidiaries
shall adopt or amend (except as may be confirmed by the Bankruptcy Court as a
part of the Prepackaged Plan or as may be required by law) any bonus, profit
sharing, compensation, stock option, pension, retirement, deferred
compensation, employment or other employee benefit plan, agreement, trust, fund
or other arrangement for the benefit or welfare of any employee, director or
former director or employee, increase the compensation or fringe benefits of

Letter, neither the Company nor any of its Subsidiaries shall grant any new or
modified severance or termination arrangement or increase or accelerate any
benefits payable under its severance or termination pay policies in effect on

                                   ARTICLE V

                             ADDITIONAL AGREEMENTS

   Section 5.1. Shareholder Approval. The Charter Amendment, the Prepackaged
Plan and the issuance of shares of Common Stock pursuant to the transactions
contemplated hereby, together with the election of directors, if appropriate,
shall be submitted for adoption and approval of the shareholders of the Company
at a meeting to be duly held for that purpose by the Company (such meeting,
including any adjournments thereof, the "Special Meeting"). The Proxy
Statement/Prospectus sent to the shareholders in connection with the approval
of the Charter Amendment and the issuance of shares at the Special Meeting will
also solicit the approval of such shareholders of the Prepackaged Plan. The
Company shall endeavor to hold the Special Meeting as soon as practicable after
the SEC Filing Documents have been declared effective and approved. Subject to
the fiduciary duties of the directors of the Company under applicable law, the
Board of Directors of the Company shall recommend that its shareholders approve
the matters set forth above and such recommendations shall be included in the
Proxy Statement/Prospectus.

Section 5.2. Solicitation of Bondholders.

     (a) Each of the parties agrees to cooperate and use their best efforts
  to cause the Exchange Offer to be consummated. Pursuant to the Exchange
  Offer, each holder of the Company's Convertible Debentures will be asked to
  surrender the Convertible Debentures owned by such holder for cancellation
  by the Company in exchange for (i) $241.50 in cash, (ii) 377.8 shares of
  Common Stock and (iii) three-year warrants to purchase an additional 188.9
  shares of Common Stock at a price of $1.50 per share, as described in the
  Warrant, the form of which is attached as Exhibit C hereto, for each $1,000
  in principal amount of Convertible Debentures owned by such holder (such
  consideration, the "Exchange Offer Consideration"); provided, however, that
  cash will be issued in lieu of fractional shares and Warrants, unless the
  Company opts, with respect to fractional Warrants, to round up to the
  nearest whole Warrant. The SEC Filing Documents sent to the holders of the
  Convertible Debentures in connection with the Exchange Offer will also
  constitute a disclosure statement for the purpose of soliciting the
  acceptances of such holders of the Prepackaged Plan. If at least 98% (or
  such lower percentage as the Company and the Purchaser Representative may
  mutually agree) of the outstanding principal amount of Convertible
  Debentures are committed to be surrendered in the Exchange Offer (such
  approval, the "Exchange Offer Condition"), the Exchange Offer will be
  consummated, the Bankruptcy Case shall not be filed and the Prepackaged
  Plan

                                       17


  will be abandoned, unless the Company and the Purchaser Representative
  otherwise mutually agree that the filing of the Bankruptcy Case and the
  confirmation of the Prepackaged Plan are in the best interest of the
  Company notwithstanding satisfaction of the Exchange Offer Condition.
  However, if the Exchange Offer Condition is not satisfied but holders of at
  least two-thirds of the outstanding principal amount of the Convertible
  Debentures that actually are voted, and a majority in number of the holders
  of the Convertible Debentures that actually vote, vote to accept the
  Prepackaged Plan as determined in accordance with applicable law and the
  Company's charter and bylaws (such acceptance, the "Bankruptcy Condition"),
  the Company shall file the Bankruptcy Case and seek confirmation of the
  Prepackaged Plan by the Bankruptcy Court. If neither the Exchange Offer
  Condition nor the Bankruptcy Condition is satisfied, either party may
  terminate this Agreement in accordance with Section 7.1(c) or (d) hereof,
  as applicable.

     (b) The parties further agree that they shall consult with each other
  prior to contacting any holder of the Convertible Debentures with respect
  to the Exchange Offer, the Exchange Consideration, the Prepackaged Plan or
  any related matter in order to develop a mutually agreeable procedure for
  such contacts and to ensure compliance with applicable securities laws and
  disclosure requirements.

   Section 5.3. SEC Filing Documents. (a) The Company shall file with the
Commission within two Business Days of the date hereof the SEC Filing Documents
substantially in the form approved by the Purchaser Representative as of the
date hereof (together with such changes, additions or deletions as the
Purchaser Representative may approve or as may be necessary or appropriate to
respond to comments of the Staff or to comply with applicable law). The Company
shall use all reasonable efforts, with assistance from the Purchasers, to the
extent reasonably applicable, to promptly respond to and satisfy any comments
of the Staff to the SEC Filing Documents and any request by the Staff for
amendments or supplements thereto. Each Purchaser shall provide promptly to the
Company all necessary information with respect to such Purchaser for inclusion
in the SEC Filing Documents, including any amendments or supplements thereto.
The Company shall use reasonable efforts to have the SEC Filing Documents
cleared by the Commission and the registration statement filed as part of the
SEC Filing Documents (the "Registration Statement") declared effective by the
Commission; provided, however, that the Company may withdraw the Registration
Statement prior to its being declared effective in the event it receives a
Superior Proposal, or terminates this Agreement, or upon filing of the
Bankruptcy Case, in each case if the Company deems such withdrawal to be
appropriate.

   (b) As soon as practicable following clearance by the Commission of the SEC
Filing Documents and effectiveness of the Registration Statement, the Company
shall mail to all its shareholders and the holders of its Convertible
Debentures that portion of the SEC Filing Documents that relates to the proxy
solicitation and Exchange Offer, including the related forms of proxies and
ballots with respect to the Exchange Offer, the Special Meeting and the
Prepackaged Plan.

   (c) Each of the Company and the Purchasers agrees to correct promptly any
information provided by it for inclusion in the SEC Filing Documents that shall
have become false or misleading in any material respect and to take all steps
necessary to file with the Commission and have declared effective or cleared by
the Commission any amendment or supplement to the SEC Filing Documents so as to
correct the same and the cause the Proxy Statement/Prospectus as so corrected
to be disseminated to the Company's shareholders and holders of its Convertible
Debentures. The parties shall work together to ensure that any amendments to
the SEC Filing Documents shall comply as to form in all material respects with
the provisions of the Securities Act, the Exchange Act, the Bankruptcy Code and
other applicable law.

   Section 5.4. No Solicitation. (a) The Company shall not, nor shall it permit
any of its Subsidiaries to, nor shall it authorize or permit any officer,
director or employee of the Company or any of its subsidiaries or any
investment banker, attorney or other advisor, agent or representative of the
Company or any of its Subsidiaries to, directly or indirectly, (i) solicit,
initiate or encourage the submission of any Proposal (as defined below), (ii)
enter into any agreement with respect to any Proposal, or (iii) participate in
any discussions or negotiations regarding, or furnish to any Person any
information with respect to, or take any other action to facilitate any
inquiries or the making of any proposal that constitutes a Proposal; provided,
however, that the

                                       18


foregoing shall not prohibit the Company from furnishing information to, or
entering into discussions or negotiations with any Person in response to an
unsolicited inquiry, request for information or Superior Proposal at any time
during the period from the date of this Agreement to the Closing Date, to the
extent required by the fiduciary obligations of the Board of Directors of the
Company determined in good faith by the Board of Directors, or from taking any
action approved by the Purchaser Representative or otherwise permitted in this
Agreement. For purposes of this Agreement, a "Proposal" means any proposal, (i)
for a tender or exchange offer, merger or other business combination involving
the Company or any of its Subsidiaries, (ii) to acquire from the Company or any
of its affiliates in any manner, directly or indirectly, any securities or
beneficial ownership thereof (excluding de minimis amounts) of the Company or
any Subsidiary or, including by lease, the principal assets of the Company and
its Subsidiaries, taken as a whole, other than a proposal by the Purchasers or
any of their affiliates, (iii) to effect any recapitalization, restructuring,
liquidation, dissolution or other extraordinary transaction with respect to the
Company and any of its Subsidiaries or (iv) other than in connection with this
Agreement, involving a "solicitation" of "proxies" (as such terms are used in
the proxy rules of the Securities and Exchange Commission) or consents to vote
any voting securities of the Company.

   (b) The Board of Directors of the Company shall not, except in connection
with the termination of this Agreement pursuant to Section 7.1 or to the extent
required by the fiduciary obligations of the directors under applicable law,
(i) withdraw or modify, or propose to withdraw or modify in a manner adverse to
the Purchasers the approval or recommendation by the Board of Directors of the
Company thereof of this Agreement or take any action having such effect;
provided, however, that a statement by the Board of Directors of the Company to
its securityholders as contemplated by Rule 14e-2 of the Exchange Act following
the Purchaser Representative's receipt of a Notice of Superior Proposal (as
defined below) shall not be deemed to constitute a withdrawal or modification
of its recommendation of this Agreement, or (ii) approve or recommend, or
propose to approve or recommend, any Proposal. Notwithstanding the foregoing,
in the event that the Board of Directors of the Company receives a Proposal
that, in the exercise of its fiduciary obligations, as determined in good faith
by the Board of Directors after consultation with counsel, it determines to be
a Superior Proposal, the Board of Directors of the Company may withdraw or
modify its approval or recommendation of this Agreement and may (subject to the
following sentence) terminate this Agreement, in each case at any time after
the fifth Business Day following the Purchaser Representative's receipt of
written notice (a "Notice of Superior Proposal") advising the Purchaser
Representative that the Board of Directors of the Company has received a
Proposal that it has determined to be a Superior Proposal, specifying the
material terms and conditions of such Superior Proposal and identifying the
Person making such Superior Proposal. The Purchaser shall have the right, for
five Business Days following the Purchaser Representative's receipt of the
Notice of Superior Proposal, to match the Superior Proposal on equal terms by
written notice to the Company. If the Purchasers elect to match the Superior
Proposal and timely notify the Company, the Company shall reject the Superior
Proposal and accept the Purchasers' matching offer, subject to the Board's
fiduciary obligations and any new Superior Proposals. Notwithstanding any
provision to the contrary herein, the Company may engage in discussions with
any Person that has made an unsolicited Proposal for the limited purpose of
determining whether such Proposal is a Superior Proposal. Nothing contained
herein shall prohibit the Company from taking and disclosing to its
securityholders a position contemplated by Rule 14e-2 of the Exchange Act
following the Purchaser Representative's receipt of a Notice of Superior
Proposal.

   (c) For purposes of this Agreement, a "Superior Proposal" means any Proposal
that the Board of Directors of the Company determines in its good faith
reasonable judgment to be more favorable than the transactions contemplated by
this Agreement.

   Section 5.5. The Prepackaged Plan. In the event the Bankruptcy Case is
commenced, the Company shall file the Prepackaged Plan with the Bankruptcy
Court. Any modifications or amendments to the Prepackaged Plan shall be subject
to timely review and approval of the Purchaser Representative in its sole
discretion. In the event the Company files the Bankruptcy Case, the parties
agree that Nevada shall be the appropriate venue for such filing, unless the
parties mutually agree on a different venue.

                                       19


   Section 5.6. Valid Issuance. The Company covenants that the Shares will,
upon issuance and upon full payment therefor in accordance with the terms
hereof, be validly issued, fully paid and nonassessable.

   Section 5.7. Confidentiality; Standstill. (a) The Purchasers agree to hold
in strict confidence all aspects of the terms and conditions of this Agreement
and all information and data concerning the Company and its Subsidiaries,
including, without limitation, information obtained in connection with the
transactions contemplated by this Agreement and all memoranda, notes, reports,
writings or other information (whatever the form or storage medium) however
reproduced or generated by the Purchasers or any of their representatives from
or with respect to any information or data disclosed by or on behalf of the
Company to the Purchasers or any of their representatives (other than
information and data that is or becomes generally available to the public other
than through disclosure by the Purchasers or any of their directors, officers,
employees or representatives in breach of this Agreement) (such information and
materials, the "Confidential Information") and will not, without the prior
written consent of the Company, disclose any such Confidential Information to
anyone other than to its directors, officers, employees and representatives
that have a need to know in connection with the furtherance of the transactions
contemplated hereby (such persons hereinafter referred to collectively as the
"Designated Individuals"); provided, that the Purchasers inform the Designated
Individuals of the confidential nature of the Confidential Information; and
provided, further, that the Purchasers direct the Designated Individuals to
treat the Confidential Information as confidential. In addition, without
limiting the foregoing, the Purchasers agree that the Confidential Information
will not be used, directly or indirectly, in the conduct of its business,
except in furtherance of the transactions contemplated by this Agreement.

   (b) In the event that the Purchasers or any of their respective directors,
officers, employees or representatives receives a request or becomes legally
compelled (by deposition, interrogatory, request for documents, subpoena, civil
investigation demand, order or similar process) to disclose any of the
Confidential Information, the Purchasers agree, prior to any such disclosure,
to (i) promptly notify the Company, (ii) consult with the Company on the
advisability of taking steps to resist or narrow such request, and (iii)
cooperate with the Company in any attempt it may make to obtain a protective
order or other appropriate remedy or assurance that confidential treatment will
be afforded such Confidential Information. In the event such protective order
or other appropriate remedy is not obtained, the Purchasers agree to furnish
only that portion of such Confidential Information that it is advised by
written opinion of counsel is legally required.

   (c) If this Agreement is terminated for any reason, the Purchasers shall, at
the Company's request, promptly return to the Company all Confidential
Information furnished, disclosed or made available by the Company to the
Purchasers or obtained or generated by the Purchasers or any of their
representatives in the course of their investigation of the Company and the
transactions contemplated by this Agreement, and the Purchasers agree not to
retain copies of any such Confidential Information (in any form whatsoever) in
such event, and not to disclose any such information or data to any third party
without obtaining the prior written consent of the Company, unless such
information and data have become generally available to the public other than
through disclosure by the Purchasers or any of their directors, officers,
employees or representatives in breach of this Agreement. In the event of any
such termination, the obligations of the Purchasers with respect to any
Confidential Information retained by the Purchasers shall survive such
termination and the Purchasers shall not utilize any such Confidential
Information to the competitive disadvantage of the Company.

   (d) If this Agreement is terminated for any reason, the Purchasers shall
not, for a period of two years from the date of any such termination, except
pursuant to a transaction approved by the Company's Board of Directors,
directly or indirectly, (i) in any manner acquire, or attempt to acquire, alone
or with other persons, any of the securities of the Company (whether directly
by purchases or indirectly by merger or similar transaction or by public
proposal to the Company or its shareholders), (ii) make, or in any way
participate in, any "solicitation" of "proxies" (as such terms are used in the
rules of the Securities and Exchange Commission) to vote any of the voting
securities of the Company or (iii) without the prior written consent of the
Company, engage in any discussions or negotiations, or submit a proposal for,
any business combination or extraordinary transaction involving the Company or
its assets.

pending or threatened litigation, investigation or proceeding to which the
Company or any of its Subsidiaries is or is threatened to be a party and of

specified above, litigation, investigation or proceeding would have a Material
Adverse Effect on the business or financial condition of the Company and its
Subsidiaries, taken as a whole.

   Section 5.11. Liquidation Analysis. If reasonably requested by the Purchaser

after the Closing Date, the parties agree that the Company shall maintain the
Company's existing director and officer liability insurance or equivalent
liability insurance ("D&O Insurance"), which insurance will provide equivalent
coverage for the Company's former and existing officers and directors;
provided, however, that if the cost of such coverage exceeds $100,000, the
Purchaser Representative shall have the right to approve such coverage, which
approval shall not be unreasonably withheld, and provided, further, that if the
cost of such coverage exceeds $200,000, the Company shall obtain as much
coverage as possible for such parties for $100,000, or such higher amount as
the Purchaser Representative may approve.

   Section 5.13. Board Nominees. The Purchasers covenant and agree that at the

Company's board of directors as of the date of this Agreement or then current
shareholders (other than nominal amounts) of the Company and, in either case,
not affiliated with the Purchasers.

   Section 5.14. Decisions on Behalf of the Purchasers. Each Purchaser hereby
agrees that all decisions to be made hereunder and rights to review, approve,
consent to or waive any item, provision or condition hereof, shall be made by
and exclusively vested in EnCap Investments L.L.C. (the "Purchaser
Representative"); provided, however, that the Purchaser Representative shall
have no liability to the Company as a Purchaser hereunder. Each Purchaser
hereby further agrees that the Company shall be entitled to rely on all
agreements, approvals, consents and waivers of EnCap Investments L.L.C. as if

Purchaser directly.

with the Closing and for no additional consideration, (i) the Purchasers shall
be allocated warrants to purchase an aggregate of 3,000,000 shares of Common
Stock at a price of $1.50 per share, which warrants shall expire three years
from the date of issuance and shall be substantially in the form of Exhibit C
hereto, together with such additional terms for all warrants to be issued at
the Closing to the Purchasers and the holders of the Company's Convertible
Debentures to adjust such warrants upon the

                                       21

       (i) the transactions contemplated by this Agreement shall not have

   Section 8.1. No Survival. All of the representations and warranties set

"Indemnifying Party") of the commencement or assertion of any action,
proceeding, demand, or claim by a third party (collectively, a "third-party
action") in respect of which such Indemnified Party shall seek indemnification
hereunder. Any failure so to notify an Indemnifying Party shall not relieve
such Indemnifying Party from any liability that it, he, or she may have to such
Indemnified Party under this Section 8.4 unless the failure to give such notice
materially and adversely prejudices such Indemnifying Party. The Indemnifying
Party shall have the right to assume control of the defense of, settle, or
otherwise dispose of such third-party action on such terms as it deems
appropriate; provided, however, that:

     (a) The Indemnified Party shall be entitled, at its own expense, to
  participate in the defense of such third-party action (provided, however,
  that the Indemnifying Party shall pay the attorneys' fees of one counsel
  (provided that if any such third-party action is brought in a jurisdiction
  other than Texas, the Indemnifying Party shall also pay the attorney's fees
  of one local counsel) to the Indemnified Party if (i) the employment of
  separate counsel shall have been authorized in writing by any such
  Indemnifying Party in connection with the defense of such third-party
  action, (ii) the Indemnifying Parties shall not have employed counsel
  reasonably satisfactory to the Indemnified Party to have charge of such
  third-party action, (iii) counsel to the Indemnified Party shall have
  reasonably concluded that there may be defenses available to the
  Indemnified Party that are different from or additional to those available
  to the Indemnifying Party, (iv) counsel to the Indemnified Party and the

  is a proceeding brought by a security holder of the Company (in such
  security holder's name or derivatively on behalf of the Company) in respect

  the opinion of the Indemnified Party, such settlement, compromise,
  admission, or acknowledgment would have a material adverse effect on its
  business;

     (c) No Indemnifying Party shall consent to the entry of any judgment or
  enter into any settlement that does not include as an unconditional term

Indemnified Party to exercise promptness in such notification shall not amount
to a waiver of such claim unless the resulting delay materially prejudices the
position of the Indemnifying Party with respect to such claim.
