                              TERMINATION AGREEMENT
                               AND GENERAL RELEASE

         This Termination and General Release ("Agreement") is made and entered
into by and between Edward J. Munden ("Executive") and DevX Energy, Inc., a
Delaware corporation ("Company").

                                    RECITALS:

         WHEREAS, the Company has employed the Executive pursuant to the terms
of that certain Employment Agreement dated as of November 10, 2000, between the
Executive and the Company (the "Employment Agreement") that grants the Executive
certain rights upon termination of the Executive's employment with the Company
for certain reasons; and

         WHEREAS, the Executive and the Company have reached the following
agreement relating to the Executive's employment with the Company, and the
termination of that employment, and to provide a complete release of the
Executive of any claims or causes of action he might have against the Company in
connection with his employment by the Company and the termination of such
employment;

         NOW THEREFORE, in consideration of the payments set forth below, and
the mutual promises and actions contained herein, it is agreed as follows:

                                   AGREEMENT:

1. TERMINATION OF EMPLOYMENT AGREEMENT. Effective August 31, 2001 (the
"Termination Date") the Executive's employment with the Company will terminate
for failure to relocate, and the Executive will relinquish all officer and
director positions, all other titles, and all authorities and employment with
respect to the Company and all members of the Company Group (as defined below).
As used herein, "Company Group" means the Company, and any entity that directly
or indirectly controls, is controlled by, or is under common control with, the
Company, and for purposes of this definition "control" means the possession,
directly or indirectly, of the power to direct or cause the direction of the
management and policies of such entity, whether through the ownership of voting
securities, by contract, or otherwise.

         Upon execution of this Agreement, the parties hereto agree that the
Employment Agreement shall terminate and the terms and provisions of the
Agreement shall supersede the Employment Agreement, provided, however, that the
covenants and agreements set forth in Paragraphs 9, 13, and 14 of the Employment
Agreement shall survive the termination of the Employment Agreement. In
addition, certain terms and descriptions set forth in the Employment Agreement
shall survive as referenced in this Agreement. Further, the terms of the October
2000 Indemnity Agreement between Executive and Company shall remain in full
force and effect.

2. PAYMENTS AND BENEFITS RELATING TO EXECUTIVE'S TERMINATION. As a result of the
Executive's termination for failure to relocate, the Executive shall receive the
following payments and benefits.

         (a) Separation Payment. As a result of Executive's termination for
         failure to relocate, and subject to the provisions of, and in
         consideration of the Executive's agreement to comply with the terms of,
         this Agreement, the Company shall pay to the Executive in a lump sum
         payment within 30 days after the Termination Date the aggregate of the
         following amounts:

                  (i) $189,853.00 which comprises the sum of the Executive's
                  unpaid Base Salary through November 6, 2001 and a prorated
                  share of the Executive's Highest Annual Bonus of $150,000 for
                  the Company's current fiscal year and the value of Executive's
                  four weeks of accrued but unpaid vacation through November 6,
                  2001; and

                  (ii) $390,000.00 which represents an amount equal to the sum
                  of the Executive's Base Salary and the Executive's Highest
                  Annual Bonus of $150,000 for the Company's current fiscal
                  year.

         (b) Welfare Benefit Payment. Company will pay Executive the current day
         value of the cash equivalent of current disability, life and family
         health benefits through November 6, 2004 in the amount of $25,000.00.
         Executive acknowledges and agrees that, because he is a Canadian
         resident and citizen, no member of the Company Group is required to
         maintain, pay for or provide continuation coverage for healthcare or
         any other benefit programs for or on account of Executive pursuant to
         COBRA. Executive also acknowledges and agrees that as of the
         Termination Date, the Company Group will no longer provide Executive
         with any life insurance, health insurance or any other welfare
         benefits.

         (c) Change of Control Payment. In the event of a Change of Control as
         defined in Paragraph 10 of the Employment Agreement on or before March
         31, 2003, the Company shall pay Executive or Executive's designee an
         additional lump sum cash payment in the amount of $780,000.00 which
         represents two times the combined value of the Executive's Base Salary
         and the Executive's Highest Annual Bonus of $150,000. Such payment
         shall be made at the same time and in the same manner as other
         executives of the Company receiving similar payments.

         (d) Cancellation of Incentive Stock Options. The grant under the
         Company's 1997 Incentive Equity Plan of incentive stock options to
         purchase 240,000 shares of Common Stock at an exercise price of $7.00
         per share made by the Company to Executive pursuant to the terms and
         conditions of that certain Incentive Stock Option Agreement dated
         October 2000 is hereby canceled.


TERMINATION AGREEMENT AND GENERAL RELEASE                                 PAGE 2

<PAGE>

         (e) Issuance of Warrant. Immediately upon execution of this Agreement,
         the Company shall issue to Executive a Warrant duly authorized by the
         Company's Board of Directors granting Executive the right to purchase
         240,000 shares of Common Stock at an exercise price of $7.00 at any
         time prior to September 27, 2003, subject to the same vesting schedule
         provided in the Warrant. All shares of Common Stock underlying the
         Warrant shall be registered with the Securities Exchange Commission as
         soon as practical under the Securities Act of 1933, as amended. A form
         of the Warrant is attached hereto as Exhibit A. The shares of Common
         Stock underlying the Warrant may be registered in the same time frame
         that the Company registers other Options available to its executives,
         if applicable.

         (f) Outplacement Services. The Company shall provide the Executive with
         outplacement services the scope and provider of which shall be selected
         by the Executive in the Executive's sole discretion, but in no event
         shall the cost of such outplacement service exceed $10,000.00.

         (g) Other Benefits. Through November 10, 2002, the Company shall
         provide to the Executive tax and financial planning services, and a
         one-time payment of $11,086.00 which represents Executive's current day
         value of a car allowance, at the same level and on the same terms as
         are provided to the Executive's peer executives of the Company and
         parking fees for the stated time period.

3. RETURN OF COMPANY PROPERTY. The Executive has returned (or, within 10 days of
executing this Agreement, will return) to the Company all of its real and
intellectual property, including all Confidential Information described in
Paragraph 9 of the Employment Agreement, except Executive will retain a cell
phone, Palm organizer, laptop computer, and home office equipment (fax,
computer, and printer).

4. CONSULTING AGREEMENT. If the Company deems such an arrangement appropriate,
Executive will agree to provide consultant services for up to six (6) months. In
his capacity as a consultant, Executive shall be available to answer questions
by telephone or otherwise provide information to the Company, its successors,
assigns, employees, agents or representatives. In no event shall such services
exceed one (1) hour per week. The Company agrees to reimburse the Executive for
reasonable out-of-pocket expenses incurred by the Executive in connection with
the performance of such services.

5. CONFIDENTIALITY. NON-COMPETE AND NON-SOLICITATION.

         (a) For the purposes of this Agreement, Confidential Information shall
         mean all trade secrets and all written, computer readable or other
         tangible forms of information, documents, memoranda, or other materials
         prepared by or on behalf of any of the Company Group, or the business,
         properties and assets thereof, including, without limitation,
         production reports, reserve reports, exploration programs or targets,
         work-over programs, capital expenditures, proposed or ongoing property
         acquisitions or divestments, employee lists and evaluation


TERMINATION AGREEMENT AND GENERAL RELEASE                                 PAGE 3
<PAGE>

         reports and financial and performance reports, plans or projections.
         Confidential Information does not include information that becomes
         generally available to the public other than as a result of
         unauthorized disclosure by the Executive. All Confidential Information
         which has or will come into Executive's possession shall be deemed to
         be confidential and proprietary to the Company and its sole and
         exclusive property. Executive agrees that he will not divulge to any
         other party any Confidential Information, except as may be required by
         law or as may be directed by the Company. Additionally, Executive
         agrees that upon Executive's termination of employment, Executive shall
         promptly return to the Company Group any and all Confidential
         Information that is in Executive's possession.

         (b) Non-Compete Agreement. Until November 10, 2002, the Executive shall
         not directly or indirectly engage in the business of the acquisition of
         oil and natural gas reserves or of the production, exploration,
         development and exploitation of oil and natural gas reserves, or any
         other business in which any member of the Company Group is directly or
         indirectly engaged as of the Termination Date; or any other business in
         which any member of the Company Group directly or indirectly engages
         during the term of the Agreement; provided, however, that the
         restriction in this Section 5 shall apply only to the reasonable and
         limited geographic area consisting of a 5 mile radius of the fields or
         leases described on Exhibit B hereto. For purposes of this Section 5,
         the Executive shall be deemed to engage in a business if he directly or
         indirectly, engages or invests in, owns, manages, operates, controls or
         participates in the ownership, management, operation or control of, is
         employed by, associated or in any manner connected with, or renders
         services or advice to, any business engaged in any of the
         above-described activities; provided, however, that the Executive may
         invest in the securities of any enterprise (but without otherwise
         participating in the activities of such enterprise) if (x) such
         securities are listed on any national or regional securities exchange
         or have been registered under Section 12(g) of the Securities Exchange
         Act of 1934 and (y) the Executive does not beneficially own (as defined
         Rule 13d-3 promulgated under the Securities Exchange Act of 1934) in
         excess of 5% of the outstanding capital stock of such enterprise;

                  The Executive agrees that if a court of competent jurisdiction
         determines that the length of time or any other restriction, or portion
         thereof, set forth in this Section 5(b) is overly restrictive and
         unenforceable, the court may reduce or modify such restrictions to
         those which it deems reasonable and enforceable under the
         circumstances, and as so reduced or modified, the parties hereto agree
         that the restrictions of this Section 5(b) shall remain in full force
         and effect. The Executive further agrees that if a court of competent
         jurisdiction determines that any provision of this Section 5(b) is
         invalid or against public policy, the remaining provisions of this
         Section 5(b) and the remainder of this Agreement shall not be affected
         thereby, and shall remain in full force and effect.

         (c) The Executive further agrees that at no time prior to May 10, 2003
         will he either directly or indirectly, solicit any employee of the
         Company to (x) accept employment, whether permanent or temporary, with
         the Executive or any business entity which competes with


TERMINATION AGREEMENT AND GENERAL RELEASE                                 PAGE 4


<PAGE>

         and/or provides services similar to the Company and with which the
         Executive is associated in any manner, or (y) to terminate such
         employee's employment with the Company.

         (d) The Executive acknowledges that the restrictions contained in this
         Section (the "Restrictions"), in view of the nature of the business in
         which the Company is engaged, are reasonable and necessary in order to
         protect the legitimate interests of the Company, and that any violation
         thereof would result in irreparable injury to the Company, and the
         Executive therefore further acknowledges that, in the event the
         Executive violates, or threatens to violate, any of such Restrictions,
         the Company shall be entitled to obtain from any court of competent
         jurisdiction, without the posting of any bond or other security,
         preliminary and permanent injunctive relief as well as damages and an
         equitable accounting of all earnings, profits, and other benefits
         arising from such violation, which rights shall be cumulative and in
         addition to any other rights or remedies in law or equity to which the
         Company or any affiliate or subsidiary of the Company may be entitled.
         If the Executive violates any of the Restrictions, the restricted
         period shall not run in favor of the Executive from the time of
         commencement of any such violation until such time as such violation
         shall be cured by the Executive to the satisfaction of the Company. If
         any Restriction, or any part thereof, is determined in any judicial or
         administrative proceeding to be invalid or unenforceable, the remainder
         of the Restrictions shall not thereby be affected and shall be given
         full effect, without regard to the invalid provisions. If the period of
         time or scope of activity in the Restrictions should be adjudged
         unreasonable in any judicial or administrative proceeding, then the
         court or administrative body shall have the power to reduce the period
         of time or the scope covered and, in its reduced form, such provision
         shall then be enforceable and shall be enforced.

6. RELEASE BY THE EXECUTIVE. In consideration for the Company's promises
provided herein, the Executive hereby releases, acquits, and forever discharges
the Company, its owners, predecessors, successors, assigns, agents, directors,
officers, employees, representatives, attorneys, divisions, subsidiaries,

incurred, up to $30,000.00 in costs and expenses (including attorney's fees)
that the Executive, or the Executive's heirs or legal representatives, have or

not limited to, as a result of any contest (regardless of the outcome thereof)
by the Company, the Executive, or others of the validity or enforceability of,
or liability under, any provision of this Agreement, or any guarantee of
performance thereof (including as a result of any contest by the Executive, or
the Executive's heirs or legal representatives, about the amount of any payment
pursuant to the Agreement), plus in each case interest on any delayed payment at
the applicable federal rate provided for in Section 7872(f) of the Code.

12. EXECUTIVE'S DEATH OR DISABILITY. In the event of the Executive's death or

TERMINATION AGREEMENT AND GENERAL RELEASE                                 PAGE 6
<PAGE>

discrimination against the Executive or any other person on the part of itself,
its employees, or its agents. The Executive specifically disclaims any liability
to the Company Group or any other person on the part of himself, his heirs, or
assigns.

14. CONFIDENTIALITY. The Executive and the Company specifically agree that they
will neither now or at any time in the future disclose or cause to be disclosed
the terms of this Agreement except (i) to their legal, tax and/or financial
advisors; (ii) to the Executive's immediate family; (iii) to the Company's
officers and directors; (iv) as required to enforce the provisions herein; or
(v) as otherwise required by applicable law. The Company and the Executive shall
not in any way cooperate or lend assistance to any parties that are now, or may
in the future be, involved in legal proceedings adverse to the Company or the
Executive except as may be required by applicable law or with regard to claims
brought by the Company or the Executive relating to or arising out of this

which Executive was involved during Executive's employment with the Company or
his relationship or position with any and all members of the Company Group.

17. MISCELLANEOUS PROVISIONS.

         (a) Assignment of Agreement. The Executive represents that he has not
         transferred or assigned, or purported to assign or transfer, to any
         person or entity any claim involving the Company or any portion thereof
         or interest therein. Any assignment in violation of the foregoing shall
         be null and void. Subject to the foregoing, this Agreement shall extend
         to, be binding upon, and inure to the benefit of the parties hereto and
         their heirs, representatives, successors, and assigns. In the event
         that there shall occur any transaction involving a Change of Control of
         the Company, then the Company shall cause the party acquiring control
         of the Company to assume the obligations of the Company under this
         Agreement. Such assumption shall be made in writing in form and
         substance reasonably satisfactory to the Executive.

         (b) Severability. If any provision of this Agreement is or may be held
         by a court of competent jurisdiction to be invalid, void, or
         unenforceable to any extent, the validity of the remaining parts,
         terms, or provisions of this Agreement shall not be affected thereby,
         and such illegal or invalid part, term, or provision shall be deemed
         not to be part of this Agreement. The remaining provisions shall
         nevertheless survive and continue in full force and effect without
         being invalidated in any way.


TERMINATION AGREEMENT AND GENERAL RELEASE                                 PAGE 7

<PAGE>

         (c) Entire Agreement. This Agreement sets forth the entire agreement
         between the parties and there are no other agreements or understandings
         other than those set out or specifically referenced in this Agreement.

         (d) Waiver. Any term or condition of this Agreement may be waived at
         any time by the party hereto which is entitled to have the benefit
         thereof, but such waiver shall only be effective if evidenced by a
         writing signed by such party, and a waiver on one occasion shall not be
         deemed to be a waiver of the same or any other type of breach on a
         future occasion. Unless there are specified times for performance or
         forbearance herein, no failure or delay by a party hereto in
         exercising any right or power hereunder shall operate as a waiver
         thereof nor shall any single or partial exercise thereof preclude any
         other or further exercise thereof or the exercise of any other right or
         power.

         (e) Texas Law. This Agreement is made within the State of Texas and
         shall in all respects be interpreted, enforced, and governed under the
         laws of the State of Texas, and shall in all cases be construed as a
         whole (according to its fair meaning, and not strictly for or against
         any of the parties).

         (f) Counterparts. This Agreement may be executed in counterparts, each
         of which shall be construed as an original for all purposes, but all of
         which taken together shall constitute one and the same Agreement.

18. SEPARATE COUNSEL. The Executive is advised by the Company that before he
signs this Agreement he should consult with an attorney.

19. 21 DAYS TO SIGN; 7-DAY REVOCATION PERIOD. By signing below, Executive
confirms that he: (1) has read this Agreement carefully; (2) has been given a
period of at least twenty-one (21) days to consider and review this Agreement;
