          6.   Administration.

          (a) This Plan shall be administered by the Committee.  The  Committee

          (b) Subject to the provisions hereof, the Committee shall have full
     and exclusive power and authority to administer this Plan and to take all
     actions that are specifically contemplated hereby or are necessary or
     appropriate in connection with the administration hereof.  The Committee
     shall also have full and exclusive power to interpret this Plan and to
     adopt such rules, regulations and guidelines for carrying out this Plan as
     it may deem necessary or proper, all of which powers shall be exercised in
     the best interests of the Company and in keeping with the objectives of
     this Plan.  The Committee may, in its discretion, provide for the extension
     of the exercisability of an Award, accelerate the vesting or exercisability
     of an Award, eliminate or make less restrictive any restrictions contained
     in an Award, waive any restriction or other provision of this Plan or an
     Award or otherwise amend or modify an Award in any manner that is either
     (i) not adverse to the Participant to whom such Award was granted or (ii)
     consented to by such Participant.  The Committee may make an award to an
     individual who it expects to become an Employee within the next six months,
     provided that such award shall be subject to the individual actually
     becoming an Employee within such time period.  The Committee may correct
     any defect or supply any omission or reconcile any inconsistency in this
     Plan or in any Award in the manner and to the extent the Committee deems
     necessary or desirable to further the Plan purposes.  Any decision of the
     Committee in the interpretation and administration of this Plan shall lie
     within its sole and absolute discretion and shall be final, conclusive and
     binding on all parties concerned.

          (c) No member of the Committee or officer of the Company to whom the
     Committee has delegated authority in accordance with the provisions of
     paragraph 7 of this Plan shall be liable for anything done or omitted to be
     done by him or her, by any member of the Committee or by any officer of the
     Company in connection with the performance of any duties under this Plan,
     except for his or her own willful misconduct or as expressly provided by
     statute.

          7.   Delegation of Authority.  The Committee may delegate to the Chief
Executive Officer and to other senior officers of the Company its duties under
this Plan pursuant to such conditions or limitations as the Committee may
establish.

                                       4

 
          8.   Awards.

          (a) The Committee shall determine the type or types of Awards to be
     made under this Plan and shall designate from time to time the individuals
     who are to be the recipients of Awards.  Each Award may be embodied in an
     Award Agreement, which shall contain such terms, conditions and limitations
     as shall be determined by the Committee in its sole discretion and shall be
     signed by the Participant to whom the Award is made and by an Authorized
     Officer for and on behalf of the Company.  Awards may consist of those
     listed in this paragraph 8(a) and may be granted singly, in combination or
     in tandem.  Awards may also be made in combination or in tandem with, in
     replacement of, or as alternatives to, grants or rights under this Plan or
     any other employee plan of the Company or any of its Subsidiaries,
     including the plan of any acquired entity. An Award may provide for the
     grant or issuance of additional, replacement or alternative Awards upon the
     occurrence of specified events, including the exercise of the original
     Award granted to a Participant.  All or part of an Award may be subject to
     conditions established by the Committee, which may include, but are not
     limited to, continuous service with the Company and its Subsidiaries,
     achievement of specific business objectives, increases in specified
     indices, attainment of specified growth rates and other comparable
     measurements of performance.  Upon the termination of employment by a
     Participant who is an Employee, any unexercised, deferred, unvested or
     unpaid Awards shall be treated as set forth in the applicable Award
     Agreement.

               (i) Option.  An Award may be in the form of an Option.  An Option
          awarded pursuant to this Plan may consist only of a Nonqualified Stock
          Option.   The price at which shares of Common Stock may be purchased
          upon the exercise of an Option shall be not less than the Fair Market
          Value of the Common Stock on the date of grant.  Subject to the
          foregoing provisions, the terms, conditions and limitations applicable
          to any Option awarded pursuant to this Plan, including the term of any
          Option and the date or dates upon which it becomes exercisable, shall
          be determined by the Committee.

               (ii) Stock Appreciation Right.  An Award may be in the form of an
          SAR.  The terms, conditions and limitations applicable to any SAR
          awarded pursuant to this Plan, including the term of any SAR and the
          date or dates upon which it becomes exercisable, shall be determined
          by the Committee.

               (iii)  Stock Award.  An Award may be in the form of a Stock
          Award, including the award of Restricted Stock or conditional stock
          units.  The terms, conditions and limitations applicable to any Stock
          Award granted pursuant to this Plan shall be determined by the
          Committee.

                                       5

 
               (iv) Cash Award.  An Award may be in the form of a Cash Award.
          The terms, conditions and limitations applicable to any Cash Award
          granted pursuant to this Plan shall be determined by the Committee.

               (v) Performance Award.  Without limiting the type or number of
          Awards that may be made under the other provisions of this Plan, an
          Award may be in the form of a Performance Award.  A Performance Award
          shall be paid, vested or otherwise deliverable solely on account of
          the attainment of one or more pre-established, objective Performance
          Goals established by the Committee prior to the earlier to occur of
          (x) 90 days after the commencement of such period of service to which
          the Performance Goal relates and (y) the lapse of 25% of such period
          of service (as scheduled in good faith at the time the goal is
          established), and in any event while the outcome is substantially
          uncertain.  A Performance Goal is objective if a third party having
          knowledge of the relevant facts could determine whether the goal is
          met.   Such a Performance Goal may be based on one or more business
          criteria that apply to the individual, one or more business units of
          the Company, or the Company as a whole, and may include one or more of
          the following: increased revenue; net income; earnings before
          interest, taxes, depreciation and amortization (EBITDA); other
          earnings measures; economic value added (EVA); cash flow measures;
          stock price; market share; return on equity or capital; return on
          revenue measures; costs; oil and gas volumes; petroleum reserve
          measures and safety and environmental performance measures.  Unless
          otherwise stated, such a Performance Goal need not be based upon an
          increase or positive result under a particular business criterion and
          could include, for example, maintaining the status quo or limiting
          economic losses (measured, in each case, by reference to specific
          business criteria). Prior to the payment of any compensation based on
          the achievement of Performance Goals, the Committee must certify in
          writing that applicable Performance Goals and any of the material
          terms thereof were, in fact, satisfied.  Subject to the foregoing
          provisions, the terms, conditions and limitations applicable to any
          Performance Awards made pursuant to this Plan shall be determined by
          the Committee.

          (b) Notwithstanding anything to the contrary contained in this Plan,
     the following limitations shall apply to any Award made hereunder:

               (i) no Participant may be granted, during any one calendar year
          period, Awards consisting of Options or SARs that are exercisable for
          more than 250,000 shares of Common Stock;

               (ii) no Participant may be granted, during any one calendar year
          period, Stock Awards covering or relating to more than 10,000 shares
          of Common Stock (the limitation set forth in this clause (ii),
          together with the limitation set forth in clause (i) above, being
          hereinafter collectively referred to as the "Stock Based Awards
          Limitations"); and

                                       6

 
               (iii)  no Participant may be granted Awards consisting of cash or
          in any other form permitted under this Plan (other than Awards
          consisting of Options or SARs or otherwise consisting of shares of
          Common Stock or units denominated in such shares) in respect of any
          one calendar year period having a value determined on the date of
          grant in excess of $2,000,000.

          9.   Payment of Awards.

          (a) General.  Payment of Awards may be made in the form of cash or
     Common Stock, or a combination thereof, and may include such restrictions
     as the Committee shall determine, including, in the case of Common Stock,
     restrictions on transfer and forfeiture provisions.  If payment of an Award
     is made in the form of Restricted Stock, the applicable Award Agreement
     relating to such shares shall specify whether they are to be issued at the
     beginning or end of the Restriction Period.  In the event that shares of
     Restricted Stock are to be issued at the beginning of the Restriction
     Period, the certificates evidencing such shares (to the extent that such
     shares are so evidenced) shall contain appropriate legends and restrictions
     that describe the terms and conditions of the restrictions applicable
     thereto.  In the event that shares of Restricted Stock are to be issued at
     the end of the Restricted Period, the right to receive such shares shall be
     evidenced by book entry registration or in such other manner as the
     Committee may determine.

          (b) Deferral.  With the approval of the Committee, amounts payable in
     respect of Awards may be deferred and paid either in the form of
     installments or as a lump-sum payment.  The Committee may permit selected
     Participants to elect to defer payments of some or all types of Awards in
     accordance with procedures established by the Committee. Any deferred
     payment of an Award, whether elected by the Participant or specified by the
     Award Agreement or by the Committee, may be forfeited if and to the extent
     that the Award Agreement so provides.

          (c) Dividends and Interest.  Rights to dividends or Dividend
     Equivalents may be extended to and made part of any Award consisting of
     shares of Common Stock or units denominated in shares of Common Stock,
     subject to such terms, conditions and restrictions as the Committee may
     establish.  The Committee may also establish rules and procedures for the
     crediting of interest on deferred cash payments and on Dividend Equivalents
     for Awards consisting of shares of Common Stock or units denominated in
     shares of Common Stock.

          (d) Substitution of Awards.  At the discretion of the Committee, a
     Participant may be offered an election to substitute an Award for another
     Award or Awards of the same or different type.

          10.  Option Exercise.   The price at which shares of Common Stock may
be purchased under an Option shall be paid in full at the time of exercise in
cash or, if elected by the optionee, the optionee may purchase such shares by
means of tendering Common Stock or 

                                       7

 
surrendering another Award, including Restricted Stock, valued at Fair Market
Value on the date of exercise, or any combination thereof. The Committee shall
determine acceptable methods for Participants to tender Common Stock or other
Awards. The Committee may provide for procedures to permit the exercise or
purchase of such Awards by use of the proceeds to be received from the sale of
Common Stock issuable pursuant to an Award. Unless otherwise provided in the
applicable Award Agreement, in the event shares of Restricted Stock are tendered
as consideration for the exercise of an Option, a number of the shares issued
upon the exercise of the Option, equal to the number of shares of Restricted
Stock used as consideration therefor, shall be subject to the same restrictions
as the Restricted Stock so submitted as well as any additional restrictions that
may be imposed by the Committee.

          11.  Taxes.  The Company shall have the right to deduct applicable
taxes from any Award payment and withhold, at the time of delivery or vesting of
cash or shares of Common Stock under this Plan, an appropriate amount of cash or
number of shares of Common Stock or a combination thereof for payment of taxes
required by law or to take such other action as may be necessary in the opinion
of the Company to satisfy all obligations for withholding of such taxes.  The
Committee may also permit withholding to be satisfied by the transfer to the
Company of shares of Common Stock theretofore owned by the holder of the Award
with respect to which withholding is required.  If shares of Common Stock are
used to satisfy tax withholding, such shares shall be valued based on the Fair
Market Value when the tax withholding is required to be made.  The Committee may
provide for loans, on either a short term or demand basis, from the Company to a
Participant to permit the payment of taxes required by law.

          12.  Amendment, Modification, Suspension or Termination.  The Board
may amend, modify, suspend or terminate this Plan for the purpose of meeting or
addressing any changes in legal requirements or for any other purpose permitted
by law, except that (i) no amendment or alteration that would adversely affect
the rights of any Participant under any Award previously granted to such
Participant shall be made without the consent of such Participant and (ii) no
amendment or alteration shall be effective prior to its approval by the
stockholders of the Company; however clause (ii) shall only apply if, and to the
extent, such approval is required by applicable legal requirements.

          13.  Assignability.  Unless otherwise determined by the Committee and
provided in the Award Agreement, no Award or any other benefit under this Plan
constituting a derivative security within the meaning of Rule 16a-1(c) under the
Exchange Act shall be assignable or otherwise transferable, except by will or
the laws of descent and distribution or pursuant to a qualified domestic
relations order as defined by the Code or Title I of the Employee Retirement
Income Security Act, or the rules thereunder.  The Committee may prescribe and
include in applicable Award Agreements other restrictions on transfer.  Any
attempted assignment of an Award or any other benefit under this Plan in
violation of this paragraph 13 shall be null and void.

                                       8

 
          14.  Adjustments.

          (a) The existence of outstanding Awards shall not affect in any manner
     the right or power of the Company or its stockholders to make or authorize
     any or all adjustments, recapitalizations, reorganizations or other changes
     in the capital stock of the Company or its business or any merger or
     consolidation of the Company, or any issue of bonds, debentures, preferred
     or prior preference stock (whether or not such issue is prior to, on a
     parity with or junior to the Common Stock) or the dissolution or
     liquidation of the Company, or any sale or transfer of all or any part of
     its assets or business, or any other corporate act or proceeding of any
     kind, whether or not of a character similar to that of the acts or
     proceedings enumerated above.

          (b) In the event of any subdivision or consolidation of outstanding
     shares of Common Stock, declaration of a dividend payable in shares of
     Common Stock or other stock split, then (i) the number of shares of Common
     Stock reserved under this Plan, (ii) the number of shares of Common Stock
     covered by outstanding Awards in the form of Common Stock or units
     denominated in Common Stock, (iii) the exercise or other price in respect
     of such Awards, (iv) the appropriate Fair Market Value and other price
     determinations for such Awards and (v) the Stock Based Awards Limitations
     shall each be proportionately adjusted by the Board to reflect such
     transaction.  In the event of any other recapitalization or capital
     reorganization of the Company, any consolidation or merger of the Company
     with another corporation or entity, the adoption by the Company of any plan
     of exchange affecting the Common Stock or any distribution to holders of
     Common Stock of securities or property (other than normal cash dividends or
     dividends payable in Common Stock), then (i) the number of shares of Common
     Stock covered by outstanding Awards in the form of Common Stock or units
     denominated in Common Stock, (ii) the exercise or other price in respect of
     such Awards, (iii) the appropriate Fair Market Value and other price
     determinations for such Awards and (iv) the Stock Based Awards Limitations
     shall each be proportionately adjusted by the Board to reflect such
     transaction; provided that such adjustments shall only be such as are
     necessary to maintain the proportionate interest of the holders of the
     Awards and preserve, without exceeding, the value of such Awards.  In the
     event of a corporate merger, consolidation, acquisition of property or
     stock, separation, reorganization or liquidation, the Board shall be
     authorized to issue substitute Awards, as appropriate, for previously
     issued Awards or to assume previously issued Awards as part of such
     adjustment.

          15.  Restrictions.  No Common Stock or other form of payment shall be
issued with respect to any Award unless the Company shall be satisfied based on
the advice of its counsel that such issuance will be in compliance with
applicable federal and state securities laws. Certificates evidencing shares of
Common Stock delivered under this Plan (to the extent that such shares are so
evidenced) may be subject to such stop transfer orders and other restrictions as
the Committee may deem advisable under the rules, regulations and other
requirements of the Securities and Exchange Commission, any securities exchange
or transaction reporting system upon which the 

                                       9

 
Common Stock is then listed or to which it is admitted for quotation and any
applicable federal or state securities law. The Committee may cause a legend or
legends to be placed upon such certificates (if any) to make appropriate
reference to such restrictions.

          16.  Unfunded Plan.  Insofar as it provides for Awards of cash, Common
Stock or rights thereto, this Plan shall be unfunded.  Although bookkeeping
accounts may be established with respect to Participants who are entitled to
cash, Common Stock or rights thereto under this Plan, any such accounts shall be
used merely as a bookkeeping convenience.  The Company shall not be required to
segregate any assets that may at any time be represented by cash, Common Stock
or rights thereto, nor shall this Plan be construed as providing for such
segregation, nor shall the Company, the Board or the Committee be deemed to be a
trustee of any cash, Common Stock or rights thereto to be granted under this
Plan.  Any liability or obligation of the Company to any Participant with
respect to an Award of cash, Common Stock or rights thereto under this Plan
shall be based solely upon any contractual obligations that may be created by
this Plan and any Award Agreement, and no such liability or obligation of the
Company shall be deemed to be secured by any pledge or other encumbrance on any
property of the Company.  Neither the Company nor the Board nor the Committee
shall be required to give any security or bond for the performance of any
obligation that may be created by this Plan.

          17.  Governing Law.  This Plan and all determinations made and actions
taken pursuant hereto, to the extent not otherwise governed by mandatory
provisions of the Code or the securities laws of the United States, shall be
governed by and construed in accordance with the laws of the State of Delaware.

          18.  Effectiveness.  This Plan shall be effective on December 2, 1998.
