144A and to institutional accredited investors (within the meaning of Rule

the Company, the Guarantors and Texas Commerce Bank National Association, as
Trustee (the "Trustee").

          1.   The Company and each of the Guarantors represent and warrant to,
and agree with, each of the Purchasers that:

          (a)  A preliminary offering circular, dated February 22, 1996 (the
     "Preliminary Offering Circular") and an offering circular, dated March 12,
     1996 (the "Offering Circular"), have been prepared in connection with the
     offering of the Notes. Any reference to the Preliminary Offering Circular
     or the Offering Circular shall be deemed to refer to and include any
     Additional Issuer Information (as defined in Section 5(f)) furnished by the
     Company prior to the completion of the distribution of the Notes. The
     Preliminary Offering Circular and the Offering Circular and any amendments
     or supplements thereto did not and will not, as of their respective dates,
     contain an untrue statement of a material fact or omit 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; provided,
     however, that this representation and warranty shall not apply to any
     statements or omissions made in reliance upon and in conformity with
     information furnished in writing to the Company by a Purchaser through
     Goldman, Sachs & Co. expressly for use therein. Each of the Preliminary
     Offering Circular and the Offering Circular, as of its date, conforms in
     all material respects to the requirements of Rule 144A(d)(4) under the Act;

          (b)  Neither the Company nor any of its subsidiaries has sustained
     since the date of the latest audited financial statements included in the
     Offering Circular 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,
     except for any such loss or interference individually or in the aggregate
     that would not have a material adverse effect on the condition (financial
     or other), business, properties, future financial outlook or results of
     operations of the Company and its subsidiaries taken as a whole (a
     "Material Adverse Effect") or except as set forth in the Offering Circular;
     neither the Company nor any of its subsidiaries has incurred any
     liabilities or obligations, direct or contingent, or entered into any
     transactions, not in the ordinary course of business, that are material to
     the Company and its subsidiaries taken as a whole; and, since the
     respective dates as of which information is given in the Offering Circular,
     there has not been any material change, on a consolidated basis, in the
     capital stock, short-term debt or long-term debt of the Company and its
     subsidiaries or any material adverse change, or any development involving a
     prospective material adverse change, in or affecting the general affairs,
     management, financial position, stockholders' equity or results of
     operations of the

                                       2

 
     Company and its subsidiaries on a consolidated basis, otherwise than as set
     forth or contemplated in the Offering Circular;

          (c)  The Company has been duly incorporated and is validly existing as
     a corporation in good standing under the laws of its jurisdiction of
     incorporation, with power and authority (corporate and other) to own its
     properties and conduct its business as described in the Offering Circular,
     and has been duly qualified as a foreign corporation for the transaction of
     business and is in good standing under the laws of each other jurisdiction
     in which it owns or leases properties or conducts any business so as to
     require such qualification, or is subject to no material liability or
     disability by reason of the failure to be so qualified in any such
     jurisdiction;

          (d)  Each subsidiary of the Company has been duly incorporated and is
     validly existing as a corporation in good standing under the laws of its
     jurisdiction of incorporation, with power and authority (corporate and
     other) to own its properties and conduct its business as described in the
     Offering Circular, and has been duly qualified as a foreign corporation for
     the transaction of business and is in good standing under the laws of each
     other jurisdiction in which it owns or leases properties or conducts any
     business so as to require such qualification, or is subject to no material
     liability or disability by reason of the failure to be so qualified in any
     such jurisdiction;

          (e)  The Company has an authorized capitalization as set forth in the
     Offering Circular, and all of the issued shares of capital stock of the
     Company have been duly and validly authorized and issued and are fully paid
     and non-assessable; all of the issued shares of capital stock of each
     subsidiary of the Company have been duly and validly authorized and issued,
     are fully paid and non-assessable and (except as otherwise stated in the
     Offering Circular) are owned directly or indirectly by the Company, free
     and clear of all liens, encumbrances, equities or claims; and except as set
     forth in the Offering Circular, there are no outstanding subscriptions,
     rights, warrants, options, calls, convertible securities, commitments of
     sale or liens related to or entitling any person to purchase or otherwise
     to acquire any shares of the capital stock of, or other ownership interest
     in, the Company or any of its subsidiaries;

          (f)  The Company and each of its subsidiaries has (A) good and
     defensible title to their respective interests in oil and gas leases, free
     and clear of any liens, mortgages, pledges, charges, defects or
     encumbrances of any kind (collectively, "Liens"), except for those (i)
     created pursuant to operating agreements, unitization and pooling
     arrangements and crude oil and gas sales contracts that secure payment of
     amounts not yet due and payable and which are of a nature and scope
     customary in similar oil and gas drilling and producing

                                       3

 
     operations or (ii) which neither individually or in the aggregate would
     have a Material Adverse Effect and (B) good and defensible title to all the
     other properties and assets reflected as owned by it in the Offering
     Circular, free and clear of any Liens, except for those (i) described in
     the Offering Circular, if any, or (ii) which in the aggregate would not
     have a Material Adverse Effect. Except to the extent described in the
     Offering Circular, the leases, options to lease, drilling concessions or
     other arrangements held by the Company and its subsidiaries reflect in all
     material respects the right of the Company and its subsidiaries to develop
     and exploit their properties, and the manner in which the Company and its
     subsidiaries acquired or otherwise procured such leases, options to lease,
     drilling concessions and other arrangements was generally consistent with
     standard industry practices for acquiring or procuring leases to explore
     acreage for hydrocarbons. The Company and each of its subsidiaries,
     respectively, has complied in all respects with the terms of oil and gas
     leases in which each purports to own an interest, and no claim has been
     asserted by any person or entity adverse to the rights of the Company or
     any of its subsidiaries as lessee or sublessee under any of such leases or
     questioning its rights to the continued possession of the leased premises
     under any such lease except for such noncompliance as would not
     individually or in the aggregate have a Material Adverse Effect. The
     concessions, reservations, licenses, permits and rights to hydrocarbons
     held by the Company and each of its subsidiaries are valid, subsisting and
     enforceable with such exceptions as are described in the Offering Circular
     or which in the aggregate would not have a Material Adverse Effect. Except
     as disclosed in the Offering Circular, the Company and each of its
     subsidiaries own or lease or have the right to use or enjoy the benefits of
     all such properties as are necessary to their respective operations as now
     conducted.

          (g)  This Agreement has been duly authorized, executed and delivered
     by the Company and the Guarantors and constitutes a valid and legally
     binding agreement of the Company and the Guarantors, enforceable against
     the Company and the Guarantors in accordance with its terms, subject, as to
     enforcement, to bankruptcy, insolvency, reorganization, moratorium and
     other laws of general applicability relating to or affecting creditor's
     rights, to general principles of equity (whether considered in a proceeding
     in equity or at law) and, as to rights of indemnification, to principles of
     public policy or federal or state securities laws relating thereto;

          (h)  The Notes and the notes having terms identical to the Notes (the
     "Exchange Notes") to be offered in exchange for the Notes (the "Exchange
     Offer") have been duly authorized by the Company and, when issued and
     delivered pursuant to this Agreement (and, as to the Exchange Notes and the

     by the Company and the Guarantors and will be in a form that would meet the
     requirements for qualification under the Trust Indenture Act of 1939, as

     a valid and legally binding instrument, enforceable against the Company and
     the Guarantors in accordance with its terms, subject, as to enforcement, to
     bankruptcy, insolvency, reorganization, moratorium and other laws of
     general applicability relating to or affecting creditors' rights and to
     general principles of equity (whether considered in a proceeding in equity
     or at law); and the Notes and the Indenture and the Exchange Notes, when

          (j)  The Credit Agreement (as defined in the Offering Circular) has
     been duly and validly authorized by the Company and the Guarantors (except
     for Electra Resources, Inc.) and is the valid and legally binding
     obligation of the Company and the Guarantors (except for Electra Resources,
     Inc.), enforceable against the Company and the Guarantors (except for
     Electra Resources, Inc.) in accordance with its terms, subject, as to

     other laws of general applicability relating to or affecting creditor's
     rights and to general principles of equity (whether considered in a
     proceeding in equity or at law);

     a basis consistent with such financial statements and the books and records
     of the Company except as otherwise specifically stated in the Offering
     Circular;

          (ab) Except as set forth in the Offering Circular, neither the Company
     nor any of its subsidiaries (i) has violated any applicable existing
     federal, state, local or international laws and regulations relating to
     protection of human health or the environment or imposing liability or
     standards of conduct concerning any Hazardous Material ("Environmental
     Laws"), lacks any permits, licenses or other approvals required of them
     under applicable Environmental Laws or is violating any term or condition
     of any such permit, license or approval, or (ii) owns or occupies any real
     property on which Hazardous Substances have been released, or which may
     reasonably be expected to be adversely affected by a release of Hazardous
     Substances released at another location, except as to clauses (i) and (ii),
     for such instances of noncompliance or releases of Hazardous substances
     which, either singly or in the aggregate, would not have a Material Adverse
     Effect. The term "Hazardous Material" means (A) any "hazardous substance"
     as defined by the Comprehensive Environmental Response, Compensation and
     Liability Act of 1980, as amended ("CERCLA"), (B) any "hazardous waste" as
     defined by the Resource Conservation and Recovery Act, as amended, (C) any
     petroleum or petroleum product, (D) any polychlorinated biphenyl, and (E)
     any pollutant or contaminant or hazardous, dangerous or toxic chemical,
     material, waste or substance regulated under or within the meaning of any
     other law relating to protection of human health or the environment or
     imposing liability or standards of conduct concerning any such chemical
     material, waste or substance. The term "release" shall have the same
     meaning given to it under CERCLA, 42 U.S.C. (S) 9601(22);

                                       10

 
          (ac) The Company and each of its subsidiaries owns or possesses or has
     the right to use the patents, patent rights, licenses, inventions,
     copyrights, know-how (including trade secrets and other unpatented and/or
     unpatentable proprietary or confidential information, systems or
     procedures), trademarks, service marks and trade names (collectively, the
     "Intellectual Property") presently employed by it in connection with, and
     material to, individually or in the aggregate, the operation of the
     businesses now operated by it, and neither the Company nor any of its
     subsidiaries has received any notice of infringement of or conflict with
     asserted rights of others with respect to the foregoing which, individually
     or in the aggregate, if the subject of an unfavorable decision, ruling or
     finding, would result in a Material Adverse Effect. The use of such
     Intellectual Property in connection with the business and operations of the
     Company and its subsidiaries does not infringe on the rights of any person,
     except as would not, individually or in the aggregate, result in a Material
     Adverse Effect;

          (ad) All tax returns required to be filed by the Company or its
     subsidiaries in all jurisdictions have been timely and duly filed, other
     than those filings being contested in good faith or except where the
     failure to so file any such returns could not, individually or in the
     aggregate, reasonably be expected to have a Material Adverse Effect. There
     are no tax returns of the Company or its subsidiaries that are currently
     being audited by state, local or federal taxing authorities or agencies
     (and with respect to which the Company or its subsidiaries has received
     notice), where the findings of such audit, if adversely determined, would
     result in a Material Adverse Effect. All taxes, including withholding
     taxes, penalties and interest, assessments, fees and other charges due or
     claimed to be due from such entities have been paid, other than those being
     contested in good faith and for which adequate reserves have been provided
     or those currently payable without penalty or interest or except if the
     failure to so pay could not reasonably be expected to have a Material
     Adverse Effect;

          (ae) The Company and each of its subsidiaries maintains insurance
     covering its properties, operations, personnel and businesses which insures
     against such losses and risks as are adequate in accordance with its
     reasonable business judgment. Neither the Company nor any of its
     subsidiaries has received notice from any insurer or agent of such insurer
     that substantial capital improvements or other expenditures will have to be
     made in order to continue such insurance. All such insurance is outstanding
     and duly in force on the date hereof and will be outstanding and duly in
     force at the Time of Delivery (as defined below);

          (af) No general labor dispute with the employees of the Company or its
     subsidiaries exists or, to the knowledge of any executive officer of the
     Company or any Guarantor after reasonable inquiry, is imminent; and neither
     the Company

                                       11

 
     nor any Guarantor is aware of any existing or imminent general labor
     disturbance by the employees of any of its principal suppliers,
     manufacturers or contractors which could reasonably be expected to have a
     Material Adverse Effect;

          (ag) There are no holders of securities of the Company or any
     Guarantor who, by reason of the execution of this Agreement or any other
     Operative Document by the Company or the Guarantors, as the case may be, or
     the consummation of the transactions contemplated hereby and thereby, have
     the right to request or demand the Company or any Guarantor to register
     under the Act or analogous foreign laws and regulations any securities held
     by them (other than pursuant to the Registration Rights Agreement);

          (ah) The Company and each of the Guarantors maintains a system of
     internal accounting controls sufficient to provide reasonable assurance
     that (i) transactions are executed in accordance with management's general
     or specific authorizations; (ii) transactions are recorded as necessary to
     permit preparation of financial statements in conformity with generally
     accepted accounting principles and to maintain accountability for assets;
     (iii) access to financial assets is permitted only in accordance with
     management's general or specific authorization and (iv) the recorded
     accountability for assets is compared with the existing assets at
     reasonable intervals and appropriate action is taken with respect thereto;

          (ai) Ernst & Young LLP, who have audited certain financial statements
     of the Company and its subsidiaries, are independent public accountants as
     defined by the Act and the rules and regulations of the Commission
     thereunder;

          (aj) The present fair saleable value of the assets of the Company and
     its subsidiaries, taken as a whole, exceeds the amount that will be
     required to be paid on or in respect of the existing debts and other
     liabilities (including the maximum amount of liability that may reasonably
     be expected to result from contingent liabilities) of the Company and its
     subsidiaries as they become absolute and matured. The assets of the Company
     and its subsidiaries, taken as a whole, do not constitute unreasonably
     small capital to carry out their business as conducted or as proposed to be
     conducted. The Company does not intend to, or believe that it will, incur
     debts beyond its ability to pay such debts as they mature. The Company does
     not intend to permit any of its subsidiaries to incur debts beyond their
     respective ability to pay such debts as they mature. Upon the issuance of
     the Notes and the Guarantees, the present fair saleable value of the assets
     of the Company and its subsidiaries, taken as a whole, will exceed the
     amount that will be required to be paid on or in respect of their existing
     debts and other liabilities (including the maximum amount of liability that
     may reasonably be expected to result from contingent liabilities) as they
     become absolute and

                                       12

 
     matured, the assets of the Company and its subsidiaries, taken as a whole,
     will not constitute unreasonably small capital to carry out their business
     as now conducted or as proposed to be conducted, including the capital
     needs of the Company and its subsidiaries, taking into account the
     projected capital requirements and capital availability of the Company and
     its subsidiaries;

          (ak) Each certificate signed by any officer of the Company or any
     Guarantor and delivered to the Purchasers or counsel for any of the
     Purchasers shall be deemed to be a representation and warranty only by such
     Company or such Guarantor, as the case may be, to the Purchasers as to the
     matters covered thereby; and

          (al) Lee Keeling and Associates, Inc. ("Keeling") is an independent
     petroleum engineer; the Purchasers have received from Keeling a true and
     correct copy of its reserve report with respect to the Company dated
     January 1, 1996 (the "Reserve Report"); all information and production data
     provided to Keeling for the preparation of the Reserve Report were true and
     correct in all material respects as of the date provided and the
     assumptions provided by the Company or any Guarantor to Keeling and used by
     Keeling in the preparation of the Reserve Report were reasonable as of the
     date provided; and the Reserve Report and the letter from Keeling to the
     Company with respect thereto (the "Keeling Letter") has been reviewed, and
     accepted as having a reasonable basis, by the Company and the Guarantors
     and the Keeling Letter has been included in the Offering Circular in good
     faith by the Company.

The Company and the Guarantors acknowledge that the Purchasers and, for purposes
of the opinions to be delivered to the Purchasers pursuant to Section 7 hereof,
counsel for the Company and the Guarantors and counsel for any of the
Purchasers, will rely upon the accuracy and truth of the foregoing
representations and hereby consent to such reliance.

     2.   Subject to the terms and conditions herein set forth, the Company
agrees to issue and sell to each of the Purchasers, and each of the Purchasers
agrees to purchase from the Company, at a purchase price of 97.5% of the
principal amount of the Notes, the principal amount of Notes set forth opposite
the name of such Purchaser in Schedule I hereto. Immediately following
consummation of the transactions contemplated hereby to occur at the Time of
Delivery, the Purchasers hereby agree, severally and not jointly, to reimburse
the Company an aggregate of $500,000, representing costs and expenses incurred
by the Company in connection with the transactions contemplated hereby and that
the Company shall not be required to submit documentation supporting the
incurrence by it of such $500,000 of expenses. The obligation of each of the
Purchasers under the preceding sentence will be in proportion

                                       13

 
to the principal amount of Notes set forth opposite their respective names in
Schedule I hereto.

     3.   The several Purchasers propose to offer the Notes for sale upon the
terms and conditions set forth in this Agreement and the Offering Circular and
each Purchaser hereby represents and warrants to, and agrees with, the Company
that:

          (a)  It will offer and sell the Notes only to: (i) persons who it
reasonably believes are Qualified Institutional Buyers within the meaning of
Rule 144A under the Act in transactions meeting the requirements of Rule 144A or
(ii) institutions which it reasonably believes are Institutional Accredited
Investors within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Act
and who, as purchasers, have executed and delivered to the Purchasers copies of
the letter set forth in Annex A to the Offering Circular;

          (b)  It is an Institutional Accredited Investor; and

          (c)  It will not offer or sell the Notes by any form of general
solicitation or general advertising, including but not limited to the methods
described in Rule 502(c) under the Act.

          Goldman, Sachs & Co. further agrees to inform the Company with respect
to the progress of the distribution of the Notes from time to time upon the
reasonable request of the Company.

     4.   (a)  The Notes to be purchased by each Purchaser hereunder will be
represented by one Global Note in book-entry form which will be deposited by or
on behalf of the Company with The Depository Trust Company ("DTC") or its
designated custodian. The Company will deliver the Notes to Goldman, Sachs & Co.
against payment by or on behalf of each Purchaser of the purchase price therefor
by wire transfer to or at the direction of the Company of Federal (same day)
funds, by causing DTC to credit the Notes to the account of Goldman, Sachs & Co.
at DTC. The Company will cause the certificates representing the Notes to be
made available to Goldman, Sachs & Co. for checking at least twenty-four hours
prior to the Time of Delivery (as defined below) at the office of DTC or its
designated custodian (the "Designated Office"). The time and date of such
delivery and payment shall be 9:30 a.m., New York City time, on March 18, 1996
or such other time and date as Goldman, Sachs & Co. and the Company may agree
upon in writing. Such time and date are herein called the "Time of Delivery."

          (b)  The documents to be delivered at the Time of Delivery by or on
behalf of the parties hereto pursuant to Section 7 hereof, including the cross-

Section 7(k) hereof, will be delivered at such time and date at the offices of

1:00 p.m., New York City time, on the New York Business Day immediately
preceding the Time of Delivery, at which meeting the final drafts of the
documents to be delivered pursuant to the preceding sentence will be available

Business Day" shall mean each Monday, Tuesday, Wednesday, Thursday and Friday
which is not a day on which banking institutions in New York are generally
authorized or obligated by law or executive order to close.

     5.   The Company and the Guarantors, jointly and severally, covenant and
agree with each of the Purchasers:

          (a)  To prepare the Offering Circular in a form reasonably approved by
you; to make no amendment or supplement to the Offering Circular which shall be

to service of process or to subject itself to general taxation in any such
jurisdiction;

          (c)  Until such time as the Exchange Offer is Consummated, to furnish

any amendment or supplement containing amendments to the financial statements
covered by such report(s), signed by the accountants, and additional copies
thereof in such quantities as you may from time to time reasonably request; and
if, at any time prior to the Consummation of the Exchange Offer, any event shall
have occurred as a result of which the Offering Circular as then amended or
supplemented would include an untrue statement of a material fact or omit to
state any material fact necessary in order to make the statements therein, in
the light of the circumstances under which they were made when such Offering
Circular is delivered, not misleading, or, if for any other reason it shall be
necessary or desirable during such same period to amend or supplement the
Offering Circular, to notify you as soon as reasonably possible; and upon your
request to prepare and furnish without charge to each of the Purchasers as many
copies as you may from time to time reasonably request of an amended Offering

Guarantees or any such substantially similar securities without your prior
written consent;

          (e)  Not to be or become, at any time prior to the expiration of the
earliest to occur of (i) three years after the Time of Delivery and (ii) such

the Investment Company Act;

successor provision thereto, in each case as may be amended from time to time);

          (g)  To execute and deliver the Registration Rights Agreement in the

Registration Rights Agreement, and to comply with all applicable federal and
state securities laws in connection with the Exchange Offer;

          (h)  If requested by you, the Company will use its best efforts to

Purchasers, confirm such advice in writing, of the issuance by any state
securities commission of any stop order suspending the qualification or
exemption of any of the Notes or Guarantees for offering or sale in any
jurisdiction, or the initiation of any proceeding for such purpose by any state
securities commission or other regulatory authority, and to use its best efforts
to prevent the issuance of any stop order or order suspending the qualification
or exemption of any of the Notes or Guarantees under any state securities or
Blue Sky laws, and if, at any time, any state securities commission or other
regulatory authority shall issue an order suspending the qualification or
exemption of any of the Notes or Guarantees under any state securities or Blue
Sky laws, to use its best efforts to obtain the withdrawal or lifting of such
order at the earliest possible time;

time as the same is no longer required under the applicable requirements of the
Act, the Notes (and all securities issued in exchange therefor or in
substitution thereof) shall bear the following legend:

Purchasers will pay all of its own costs and expenses, including the fees of its

     7.   The obligations of each Purchaser hereunder shall be subject, in its

circumstances under which they are made;

          (b)  Latham & Watkins, counsel for the Purchasers, shall have

     corporate power to execute, deliver and perform their obligations under

                                       21

 
     the other Operative Documents to which they are a party and to consummate
     the transactions contemplated hereby and thereby, including without
     limitation the corporate power to issue, sell and deliver the Notes and the
     Exchange Notes and to issue the Guarantees and the Exchange Note
     Guarantees, as applicable, as provided herein and therein;

               (xi)   None of the execution, delivery and performance of this
     Agreement, the issuance and sale of the Notes, the issuance of the
     Guarantees, the application of the proceeds from the issuance and sale of

     set forth in the Offering Circular will violate Section 7 of the Exchange
     Act, or any regulation promulgated thereunder, including, without
     limitation, Regulation G, T, U, or X promulgated by the Board of Governors
     of the Federal Reserve System.

               (xii)  No consent, approval, authorization, order, registration

     issuance of the Exchange Note Guarantees in the Exchange Offer or the
     consummation by the Company or the Guarantors of the transactions
     contemplated by this Agreement or the other Operative Documents, except for
     (i) the filing of a registration statement by the Company with the
     Commission pursuant to the Act pursuant to Section 5(g) hereof, (ii) the
     filing of a notice on Form D by the Company with the Commission pursuant to
     Section 5(i) hereof, (iii) such consents, approvals, authorizations,
     registrations or qualifications as may be required under state securities
     or Blue Sky laws in connection with the purchase and distribution of the

     or resale registration contemplated by the Offering Circular and described
     in the Registration Rights Agreement, and (v) such consents, approvals
     authorizations, registrations or qualifications as have been obtained or
     made; such counsel may state that the opinions set forth in this paragraph
     are based upon consideration only of those statutes, rules and regulations
     that, in such counsel's experience are normally applicable to transactions
     such as those contemplated by the issuance and sale of the Notes, the
     issuance of the Guarantees of the Notes, the issuance of the Exchange Notes
     or the issuance of the Exchange Note Guarantees in the Exchange Offer, or
     the consummation by the Company or the Guarantors of the transactions
     contemplated by this Agreement or the other Operative Documents;

               (xiii) The statements set forth in the Offering Circular under
     the caption "Description of Notes," insofar as they purport to summarize
     the terms of the Notes and the Indenture, and under the caption
     "Description of Other

                                       22

 
     Indebtedness," insofar as they purport to describe the provisions of the
     documents referred to therein, are materially accurate and fairly present
     such documents in all material respects;

               (xiv)  Neither the Company nor any of its subsidiaries is an
     "investment company", or an entity "controlled" by an "investment company",
     as such terms are defined in the Investment Company Act;

               (xv)   No registration of the Notes under the Act, and no
     qualification of an indenture under the Trust Indenture Act with respect
     thereto, is required for the offer, sale and initial resale of the Notes by
     the Purchasers in the manner contemplated by this Agreement and the
     Offering Circular, other than any registration or qualification that may be
     required in connection with the Exchange Offer contemplated by the Offering
     Circular or in connection with the Registration Rights Agreement; and

               (xvi)  Each of the Preliminary Offering Circular and the Offering
     Circular, as of its date, and each amendment or supplement thereto, as of
     its date (except for the reserve data, financial statements and related
     schedules and other financial information included therein, as to which no
     opinion need be expressed), complied as to form in all material respects
     with the requirements of Rule 144A of the Act.

               In addition, such counsel shall state that they have participated
     in conferences with officers and representatives of the Company and the
     Guarantors, accountants of the Company and the Guarantors and
     representatives of the Purchasers at which the contents of the Offering
     Circular and related matters were discussed and, subject to the fact that
     such counsel shall not assume any responsibility for and cannot guarantee
     the accuracy, completeness or fairness of the statements contained in the
     Offering Circular and shall have made no independent check or verification
     thereof, on the basis of the foregoing, such counsel shall state that it
     has no reason to believe that the Offering Circular and any further
     amendments or supplements thereto made by the Company prior to the Time of
     Delivery (other than the reserve data, financial statements and related
     schedules and other financial information contained in the Offering
     Circular, as to which such counsel need express no opinion) contained as of
     its date or contains as of the Time of Delivery an untrue statement of a
     material fact or omitted or omits, as the case may be, to state a material
     fact necessary to make the statements therein, in the light of the
     circumstances under which they were made, not misleading.

                                       23

 
          (d)  Joe Callaway, counsel for the Company and the Guarantors, shall
have furnished to you his written opinion, dated the Time of Delivery, in form
and substance satisfactory to you, to the effect that:

               (i)    The Company has been duly qualified to transact business
     as a foreign corporation and is in good standing under the laws of each
     jurisdiction (other than its jurisdiction of incorporation) in which it
     owns or leases material property or conducts material business so as to
     require such qualification, except where failure to be so qualified in any
     such jurisdiction would not have a material adverse effect on the financial
     position of the Company and its subsidiaries, taken as a whole;

               (ii)   Each subsidiary of the Company has been duly incorporated
     and is validly existing as a corporation in good standing under the laws of
     its jurisdiction of incorporation, with full corporate power and authority
     to own its properties and conduct its business as described in the Offering
     Circular; and has been duly qualified to transact business as a foreign
     corporation and is in good standing under the laws of each other
     jurisdiction in which it owns or leases material property or conducts
     material business so as to require such qualification, except where the
     failure to be so qualified in any such jurisdiction would not have a
     material adverse effect on the financial position of the Company and its
     subsidiaries, taken as a whole;

               (iii)  All of the issued shares of capital stock of each
     subsidiary of the Company have been duly authorized and validly issued, are
     fully paid and non-assessable, and except as otherwise stated in the
     Offering Circular are owned of record by the Company directly or
     indirectly, and, to such counsel's actual knowledge, the Company has not
     received notice of any adverse claim;

               (iv)   The issuance and sale of the Notes and the issuance of the
     Guarantees and the issuance of the Exchange Notes and the issuance of the
     Exchange Note Guarantees in the Exchange Offer and the compliance by the
     Company and the Guarantors with all of the provisions of this Agreement and
     the other Operative Documents and the consummation of the transactions
     herein and therein contemplated will not conflict with, violate or result
     in a breach of any of the terms and provisions of, or constitute a default
     under, any indenture, mortgage, deed of trust, sale/leaseback agreement,
     loan agreement or other agreement or instrument to which the Company or any
     of its subsidiaries is a party or to which any of the property or assets of
     the Company or any of its subsidiaries is subject and, in either case, that
     is actually known to such counsel and that is material to the Company and
     its subsidiaries, taken as a whole, nor will such action result in any
     violation of the provisions of the respective Certificate of Incorporation,
     Articles of Incorporation or By-laws of the Company

                                       24

 
     or any of its subsidiaries or any United States statute, rule or regulation
     or the Delaware General Corporation Law or any order of any court or
     governmental agency or body having jurisdiction over the Company or any of
     its subsidiaries or any of their properties, provided, however, that this
     opinion does not address the securities laws of the United States, the
     states thereof, and any other applicable jurisdiction;

               (v)    The statements set forth in the Offering Circular under
     the captions "Business--Regulation" and "Business--Environmental Matters,"
     insofar as they purport to describe the provisions of the laws referred to
     therein, are materially accurate and complete in all material respects;

               (vi)   Other than as disclosed in the Offering Circular, there
     are no legal or governmental proceedings pending or, to such counsel's
     actual knowledge, overtly threatened to which the Company or any of its
     subsidiaries is a party or of which any property of the Company or any of
     its subsidiaries is the subject which could reasonably be expected,
     individually or in the aggregate, to have a material adverse effect on the
     current or future financial position or results of operations of the
     Company and its subsidiaries, taken as a whole, to materially adversely
     affect the issuance and sale of the Notes or the issuance of the Guarantees
     or to materially affect the validity of any Operative Document; and, to
     such counsel's actual knowledge, no such proceedings are threatened overtly
     or contemplated by governmental authorities or threatened overtly by
     others;

               (vii)  To such counsel's actual knowledge, neither the Company
     nor any of its subsidiaries is in violation of its Certificate of
     Incorporation, Articles of Incorporation or By-laws; or is in default in
     the performance or observance of any obligation, covenant or condition
     contained in any indenture, mortgage, deed of trust, loan agreement, lease
     or other agreement or instrument to which it is a party or by which any of
     its properties may be bound, in each case where any such default has a
     material adverse effect on the financial position of the Company and its
     subsidiaries, taken as a whole.

               (viii) To such counsel's actual knowledge, except as set forth in
     the Offering Circular, there are no outstanding subscriptions, rights,
     warrants, options, calls, convertible securities, commitments of sale or
     liens related to or entitling any person to purchase or otherwise to
     acquire any shares of the capital stock of, or other ownership interest in,
     the Company or any of its subsidiaries.

               (ix)   The Credit Agreement has been duly authorized, executed
     and delivered by the Company and the Guarantors (except for Electra
     Resources, Inc.) and constitutes a valid and legally binding obligation of
     the Company and the Guarantors (except for Electra Resources, Inc.),
     enforceable against the Company

                                       25

 
     and the Guarantors (except for Electra Resources, Inc.) in accordance with
     its terms, subject, as to enforcement, to bankruptcy, fraudulent transfer,
     insolvency, reorganization, moratorium and other laws of general
     applicability relating to or affecting creditors' rights and to general
     principles of equity (whether considered in a proceeding in equity or at
     law);

          In addition, such counsel shall state that he has participated in
conferences with officers and representatives of the Company and the Guarantors,
accountants of the Company and the Guarantors and representatives of the
Purchasers at which the contents of the Offering Circular and related matters
were discussed and, subject to the fact that such counsel shall not assume any
responsibility for and cannot guarantee the accuracy, completeness or fairness
of the statements contained in the Offering Circular and shall have made no
independent check or verification thereof, on the basis of the foregoing, such
counsel shall state that it has no reason to believe that the Offering Circular
and any further amendments or supplements thereto made by the Company prior to
the Time of Delivery (other than the reserve data, financial statements and
related schedules and other financial information contained in the Offering
Circular, as to which such counsel need express no opinion) contained as of its
date or contains as of the Time of Delivery an untrue statement of a material
fact or omitted or omits, as the case may be, to state a material fact necessary
to make the statements therein, in the light of the circumstances under which
they were made, not misleading.

          (e)  On the date of the Offering Circular prior to the execution of
this Agreement, Ernst & Young LLP shall have furnished to you a letter or

general affairs, management, financial position, stockholders' equity or results
of operations of the Company or any of its subsidiaries, on a consolidated
basis, otherwise than as set forth or contemplated in the Offering Circular, the
effect of which, in any such case described in clause (i) or (ii), is in the
judgment of the Purchasers so material and adverse as to make it impracticable
or inadvisable to proceed with the offering or the delivery of the Notes on the
terms and in the manner contemplated in this Agreement and in the Offering
Circular;

          (h)  On or after the date hereof (i) no downgrading shall have

in this clause (iii), in the judgment of the Purchasers, makes it impracticable
or inadvisable to proceed with the offering or the delivery of the Notes on the
terms and in the manner contemplated in the Offering Circular; or (iv) the
occurrence of any material adverse change in financial, political or economic
conditions in the United States or elsewhere which, in the judgment of the
Purchasers, would materially and adversely affect the financial markets or the

after reasonable inquiry, threatened against the Company or any of its
subsidiaries before any court or arbitrator or any governmental body, agency or
official that, if adversely determined, would prohibit, interfere with or
adversely affect the issuance or sale of the Notes or the issuance of the
Guarantees or would have a Material Adverse Effect, or in any manner draw into
question the validity of this Agreement or the other Operative Documents; and no
stop order preventing the use of the Offering Circular, or any amendment or
supplement thereto, or any order asserting that any of the transactions
contemplated by this Agreement are subject to the registration requirements of

hereby and the transactions described in the Offering Circular under the caption

     8.   (a)  The Company and the Guarantors, jointly and severally, agree to
indemnify and hold harmless each Purchaser against any losses, claims, damages
or liabilities to which such Purchaser may become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon an untrue statement or alleged
untrue statement of a material fact contained in any Preliminary Offering
Circular or the Offering Circular, or any amendment or supplement thereto, or
arise out of or are based upon the omission or alleged omission to state therein
a material fact necessary to make the statements therein not misleading, and
will reimburse each Purchaser for any legal or other expenses reasonably
incurred by such Purchaser in connection with investigating or defending any
such action or claim as such expenses are incurred; provided, however, that the
Company and the Guarantors shall not be liable in any such case to the extent
that any such loss, claim, damage or liability arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission
made in any Preliminary Offering Circular or the Offering Circular or any such
amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by any Purchaser through Goldman, Sachs &
Co. expressly for use therein.

          (b)  Each Purchaser will indemnify and hold harmless the Company and
the Guarantors against any losses, claims, damages or liabilities to which the
Company or any Guarantor may become subject, under the Act or otherwise, insofar
as such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon an untrue statement or alleged untrue statement
of a material fact contained in any Preliminary Offering Circular or the
Offering Circular, or any amendment or supplement thereto, or arise out of or
are based upon the omission or alleged omission to state therein a material fact
or necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in any Preliminary Offering
Circular or the Offering Circular or any such amendment or supplement in
reliance upon and in conformity with written information furnished to the
Company by such Purchaser through Goldman, Sachs & Co. expressly for use
therein; and will reimburse the Company and the Guarantors for any legal or
other expenses

                                       29

 
reasonably incurred by the Company and the Guarantors in connection with
investigating or defending any such action or claim as such expenses are
incurred.

          (c)  Promptly after receipt by an indemnified party under subsection
(a) or (b) above of notice of the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the indemnifying party in
writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party otherwise than under such subsection. In case any such
action shall be brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it shall wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel satisfactory to such indemnified party (who shall not,
except with the consent of the indemnified party, be counsel for the
indemnifying party), and, after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party shall not be liable to such indemnified party under such
subsection for any legal expenses of other counsel or any other expenses, in
each case subsequently incurred by such indemnified party, in connection with
the defense thereof other than reasonable costs of investigation.
Notwithstanding the foregoing, any indemnified party shall have the right to
employ separate counsel in any such action and participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
the indemnified party unless the indemnified party shall have been advised by
counsel that representation of the indemnified party by counsel provided by the
indemnifying party would be inappropriate due to actual or potential conflicting
interests between the indemnifying party and the indemnified party, including
situations in which there are one or more legal defenses available to the
indemnified party that are different from or additional to those available to
the indemnifying party; provided, however, that the indemnifying party shall
not, in connection with any one such action or proceeding or separate but
substantially similar actions or proceedings arising out of the same general
allegations, be liable for the fees and expenses of more than one separate firm
of attorneys at any time for all indemnified parties, except to the extent that
local counsel, in addition to its regular counsel, is required in order to
effectively defend against such action or proceeding. No indemnifying party
shall, without the written consent of the indemnified party, effect the
settlement or compromise of, or consent to the entry of any judgment with
respect to, any pending or threatened action or claim in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified party is an actual or potential party to such action or claim)
unless such settlement, compromise or judgment (i) includes an unconditional
release of the indemnified party from all liability arising out of such action
or claim and (ii) does not include a statement as to, or an admission of, fault,
culpability or a failure to act, by or on behalf of any indemnified party.

                                       30

 
          (d)  If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative benefits received by the Company and the Guarantors on the one hand and
the Purchasers on the other from the offering of the Notes. If, however, the
allocation provided by the immediately preceding sentence is not permitted by
applicable law or if the indemnified party failed to give the notice required
under subsection (c) above, then each indemnifying party shall contribute to
such amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company and the Guarantors on the one hand and the Purchasers on
the other in connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities (or actions in respect thereof), as well
as any other relevant equitable considerations. The relative benefits received
by the Company and the Guarantors on the one hand and the Purchasers on the
other shall be deemed to be in the same proportion as the total net proceeds
from the offering (before deducting expenses) received by the Company bear to
the total underwriting discounts received by the Purchasers, in each case as set
forth in the Offering Circular, provided that the total underwriting discounts
shall be deemed to be reduced, and the total net proceeds received by the
Company and the Guarantors shall be deemed to be increased, by the amount of
expenses of the Company reimbursed by the Purchasers pursuant to Section 2
hereof. The relative fault shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company and the Guarantors on the one hand or the Purchasers on
the other and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company, the
Guarantors and the Purchasers agree that it would not be just and equitable if
contribution pursuant to this subsection (d) were determined by pro rata
allocation (even if the Purchasers were treated as one entity for such purpose)
or by any other method of allocation which does not take account of the
equitable considerations referred to above in this subsection (d). The amount
paid or payable by an indemnified party as a result of the losses, claims,
damages or liabilities (or actions in respect thereof) referred to above in this
subsection (d) shall be deemed to include 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 subsection (d),
no Purchaser shall be required to contribute any amount in excess of the amount
by which the total discounts received by it under this Agreement exceeds the
amount of any damages which such Purchaser has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission. The Purchasers' obligations in this subsection (d) to

                                       31

 
contribute are several in proportion to their respective underwriting
obligations and not joint.

          (e)  The obligations of the Company and the Guarantors under this
Section 8 shall be in addition to any liability which the Company and the
Guarantors may otherwise have and shall extend, upon the same terms and
conditions, to each person, if any, who controls any Purchaser within the
meaning of the Act; and the obligations of the Purchasers under this Section 8
shall be in addition to any liability which the respective Purchasers may
otherwise have and shall extend, upon the same terms and conditions, to each
officer and director of the Company or any Guarantor and to each person, if any,
who controls the Company or any Guarantor within the meaning of the Act.

     9.   (a)  If any Purchaser shall default in its obligation to purchase the
Notes which it has agreed to purchase hereunder, you may in your discretion
arrange for you or another party or other parties to purchase such Notes on the
terms contained herein. If within thirty-six hours after such default by any
Purchaser you do not arrange for the purchase of such Notes, then the Company
shall be entitled to a further period of thirty-six hours within which to
procure another party or other parties satisfactory to you to purchase such
Notes on such terms. In the event that, within the respective prescribed
periods, you notify the Company that you have so arranged for the purchase of
such Notes, or the Company notifies you that it has so arranged for the purchase
of such Notes, you or the Company shall have the right to postpone the Time of
Delivery for a period of not more than seven days, in order to effect whatever
changes may thereby be made necessary in the Offering Circular, or in any other
documents or arrangements, and the Company agrees to prepare promptly any
amendments to the Offering Circular which in your opinion may thereby be made
necessary. The term "Purchaser" as used in this Agreement shall include any
person substituted under this Section with like effect as if such person had
originally been a party to this Agreement with respect to such Notes.

     (b)  If, after giving effect to any arrangements for the purchase of the
Notes of a defaulting Purchaser or Purchasers by you and the Company as provided
in subsection (a) above, the aggregate principal amount of such Notes which
remains unpurchased does not exceed one-eleventh of the aggregate principal
amount of all the Notes, then the Company shall have the right to require each
non-defaulting Purchaser to purchase the principal amount of Notes which such
Purchaser agreed to purchase hereunder and, in addition, to require each non-
defaulting Purchaser to purchase its pro rata share (based on the principal
amount of Notes which such Purchaser agreed to purchase hereunder) of the Notes
of such defaulting Purchaser or Purchasers for which such arrangements have not
been made; but nothing herein shall relieve a defaulting Purchaser from
liability for its default.

                                       32

 
     (c)  If, after giving effect to any arrangements for the purchase of the
Notes of a defaulting Purchaser or Purchasers by you and the Company as provided
in subsection (a) above, the aggregate principal amount of Notes which remains
unpurchased exceeds one-eleventh of the aggregate principal amount of all the
Notes, or if the Company shall not exercise the right described in subsection
(b) above to require non-defaulting Purchasers to purchase Notes of a defaulting
Purchaser or Purchasers, then this Agreement shall thereupon terminate, without
liability on the part of any non-defaulting Purchaser or the Company, except for
the expenses to be borne by the Company and the Purchasers as provided in
Section 6 hereof and the indemnity and contribution agreements in Section 8
hereof; but nothing herein shall relieve a defaulting Purchaser from liability
for its default.

     10.  The respective indemnities, agreements, representations, warranties
and other statements of the Company, the Guarantors and the several Purchasers,
as set forth in this Agreement or made by or on behalf of them, respectively,
pursuant to this Agreement, shall remain in full force and effect regardless of
any investigation (or any statement as to the results thereof) made by or on
behalf of any Purchaser or any controlling person of any Purchaser, or the
Company or any Guarantor or any officer or director or any controlling person of
the Company or any Guarantor and shall survive delivery of and payment for the
Notes.

     11.  If the Notes or the Guarantees are not delivered by or on behalf of
the Company and the Guarantors, as applicable, as provided herein, the Company
and the Guarantors will reimburse the Purchasers for all out-of-pocket expenses,
including fees and disbursements of counsel, reasonably incurred by the
Purchasers in making preparations for the purchase, sale and delivery of the
Notes, but the Company and the Guarantors shall then be under no further
liability to any Purchaser except as provided in Sections 6 and 8 hereof.

     12.  All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Purchasers shall be delivered or sent by mail, overnight
courier or facsimile transmission to you as the Representative, in care of
Goldman, Sachs & Co., 85 Broad Street, New York, New York 10004, Attention:
Registration Department (facsimile number, 212-902-3000); and if to the Company
or the Guarantors shall be delivered or sent by mail, overnight courier or
facsimile transmission to 5735 Pineland Drive, Dallas, Texas 75231, Attention:
President (facsimile number, 214-265-4777). Any such statements, requests,
notices or agreements shall take effect upon receipt thereof.

     13.  This Agreement shall be binding upon, and inure solely to the benefit
of, the Purchasers, the Company, the Guarantors and, to the extent provided in
Sections 8 and 10 hereof, the officers and directors of the Company, any
Guarantor and any Purchaser and each person who controls the Company, any
Guarantor or any of the Purchasers, and their respective heirs, executors,
administrators, successors and

                                       33

 
assigns, and no other person shall acquire or have any right under or by virtue
of this Agreement. No purchaser of any of the Notes from any Purchaser shall be
deemed a successor or assign by reason merely of such purchase.

     14.  Time shall be of the essence of this Agreement.

     15.  THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK.

     16.  This Agreement may be executed by any one or more of the parties
hereto in any number of counterparts, each of which shall be deemed to be an
original, but all such respective counterparts shall together constitute one and
the same instrument.
