| |  | 3.2.3 | Company shall pay to Employee, on or before the last day of his employment
hereunder, a lump sum cash payment for all (a) vacation time carried forward

| | 3.3 | In the event Employee elects to terminate this Agreement as provided in
paragraph 3.1 above:
| | --- | --------------------------------------------------------------------------------------------

| |  | 3.3.1 | Employee agrees to serve to the end of the term, or extended term hereof, unless
waived by Company.                                                 
| |  | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------

| | 3.5 | Company may terminate this Agreement for Cause (as hereinafter
defined in this paragraph 3.5) upon written notice of such termination to
Employee by Company. Any termination of this Agreement by Company for Cause
shall be effective thirty (30) days after written notice of termination for
Cause is given by Company to Employee. If Company terminates this Agreement for
Cause, Company shall have no liability or obligation to Employee thereafter
under this Agreement except for the payment of his salary and other benefits
through the month of discharge, prorated in the case of salary for the month of
discharge on a daily basis to the date of termination. As used in this
Agreement, the term Cause means (a) Employee is found guilty of,
admits in writing facts amounting to, or is held civilly liable for fraud,
embezzlement or dishonesty, (b) Employee is convicted of a felony involving
a crime of moral turpitude or any other felony if the Board of Directors of the
Company in good faith determines that the continued employment of the Employee
would be materially detrimental to the Company (in any case which felony through
lapse of time or otherwise is not subject to appeal), (c) Employee knowingly
discloses trade secrets or confidential Company matters to unauthorized persons,
(d) Employee willfully breaches or habitually neglects any duties he is required
to perform under the terms of this Agreement and any such breach or neglect is
not cured within thirty (30) days after Company has provided Employee with
written notice of such breach or neglect, (e) Employee materially breaches any
of the other material terms of this Agreement and any such breach is not cured
within thirty (30) days after the Company has provided Employee with written
notice of such breach, and (f) the occurrence of an action or finding described
in paragraph 15, except as otherwise provided in paragraph 15. The waiver by
Company of a breach of any provision of this Agreement by Employee shall not
operate or be construed as a waiver of any subsequent breach by Employee.
| | 3.6 | In the event Company terminates this Agreement or discharges Employee other than
as provided in paragraphs 3.1, 3.4 or 3.5 above, Employee shall be entitled to
receive on the date of such termination or discharge:

11.        Right to Invest.

| | Nothing
in this Agreement is intended or shall be construed to limit Employees
right (i) to engage in passive personal investments, including, but not limited
to, holding as an investment not more than five percent (5%) of any class of the
issued and outstanding and publicly traded (on a recognized national or regional
securities exchange or in the over-the-counter market) capital stock or other
securities of any corporation or other entity that conducts activities that
compete with the business of Company or any affiliate of Company; or (ii) to
invest, individually or with others, in oil and gas prospects, subject, however,
in the case of oil and gas prospects to the following conditions:
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 11.1 | Company must have first had the right and opportunity to purchase all of the
interest in any prospect made available to Employee, even if this would preclude
Employees participation.                                                                                                                                                                                                                    
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| | 11.2 | Company must have made known its election either to participate in less than the
full interest made available to Employee and have no desire to acquire an
additional interest, or declined to participate at all in the prospect. If
Company elects to participate in less than the full interest made available to
Employee, Employee may invest in the portion of such interest not acquired by
Company.
| | 11.3 | Employee must purchase his interest in the oil and gas prospect on terms which
are no more favorable than those made available to Company.                                                                                                                                                                                                                                                                 

12.      Disability During Employment.

| | If
Employee shall become unable to perform his duties by reason of disability, he
shall be entitled to receive, in addition to any insurance benefits he may
receive, all of his salary for the first one (1) month of his disability, and
one-half (1⁄2) of his salary for the next three (3) months of disability.
Periods of disability shall not be cumulative so long as they are separated by
at least ninety (90) days of continuous service.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| | The
term disability shall mean disability which, in the opinion of a
doctor satisfactory to Company, renders Employee unable to perform his duties
hereunder as evidenced by such doctors certificate. The date disability
commences shall be the date Employee first absents himself from work during a
continuous period of disability.                                                                                                      

13.      Merger or Acquisition.

| | In
the event Company should be acquired by or merged into another company, by
signature of Companys authorized representatives, Company hereby agrees
that this Employment Agreement shall be binding upon Company, its successors and
assigns, and shall be disclosed to any party considering merger with, or
acquisition of, Company.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

14.      Arbitration.

| | 14.1 | If a dispute arises out of or related to this Agreement and the dispute cannot
be settled through direct discussions, Company and Employee agree that they
shall first endeavor to settle the dispute in an amicable fashion. If such
efforts fail to resolve the dispute, the dispute shall, except as otherwise
provided in paragraph 17, be resolved as follows:
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  | 14.1.1 | Except as provided in paragraph 14.1.2 below, any and all claims, demands, cause
of action, disputes, controversies, and other matters in question arising out of
or relating to this Agreement, any provision hereof, the alleged breach thereof,
or in any way relating to the subject matter of this Agreement, involving
Company, Employee, and/or their respective representatives, even though some or
all of such claims allegedly are extracontractual in nature, whether such claims
sound in contract, tort, or otherwise, at law or in equity, under state or
federal law, whether provided by statute or the common law, for damages or any
other relief, shall be resolved by binding arbitration pursuant to the Federal
Arbitration Act in accordance with the Commercial Arbitration Rules then in
effect with the American Arbitration Association (the AAA). The
arbitration proceeding shall be conducted in Houston, Texas. The arbitration may
be initiated by either party by providing to the other a written notice of
arbitration specifying the claims, and the parties shall thereafter endeavor to
agree on an arbitrator. If within thirty (30) days of the notice of initiation
of the arbitration procedure, the parties are unable to agree on an arbitrator,
the party requesting arbitration shall file a request with the AAA that the
Houston, Texas office of the AAA provide a list of potential arbitrators to both
parties. The parties shall thereafter have sixty (60) days to select an
arbitrator from such list, with such selection to be by mutual agreement. If the
parties fail to select an arbitrator within such time by mutual agreement, then
either party may request that the Chief Judge of the U.S. District Court for the
Southern District of Texas appoint an arbitrator, and any such appointment shall
be binding. The arbitrator, utilizing the Commercial Arbitration Rules of the
American Arbitration Association, shall within 120 days of his or her selection,
resolve all disputes between the parties. There shall be no transcript of the
hearings before the arbitrator. The arbitrators decision shall be in
writing, but shall be as brief as possible. The arbitrator shall not assign the
reasons for his or her decision. The arbitrators decision shall be final
and non-appealable to the maximum extent permitted by law. Judgment upon any
award rendered in any such arbitration proceeding may be entered by any federal
or state court having jurisdiction. This agreement to arbitrate shall be
enforceable in either federal or state court. The enforcement of this agreement
to arbitrate and all procedural aspects of this agreement to arbitrate,
including but not limited to, the construction and interpretation of this
agreement to arbitrate, the issues subject to arbitration (i.e., arbitrability),
the scope of the arbitrable issues, allegations of waiver, delay or defenses to
arbitrability, and the rules governing the conduct of the arbitration, shall be
governed by and construed pursuant to the Federal Arbitration Act and shall be
decided by the arbitrator. In deciding the substance of any such claims, the
arbitrator shall apply the substantive laws of the State of Texas (excluding
Texas choice-of-law principles that might call for the application of some other
States law); provided, however, it is expressly agreed that the arbitrator
shall have no authority to award treble, exemplary, or punitive damages under
any circumstances regardless of whether such damages may be available under
Texas law, the parties hereby waiving their right, if any, to recover treble,
exemplary, or punitive damages in connection with any such claims.

| |  | 14.1.2 | Notwithstanding the agreement to arbitrate contained in paragraph 14.1.1 above,
in the event that either party wishes to seek a temporary restraining order, a
preliminary or temporary injunction, or other injunctive relief in connection
with any or all such claims, demands, cause of action, disputes, controversies,
and other matters in question arising out of or relating to this Agreement, any
provision hereof, the alleged breach thereof, or in any way relating to the
subject matter of this Agreement, involving Company, Employee, and/or their
respective representatives, including disputes arising out of a breach or
alleged breach of paragraph 4 or 20, even though some or all of
such claims allegedly are extra-contractual in nature, whether such claims sound
in contract, tort, or otherwise, at law or in equity, under state or federal
law, whether provided by statute or the common law, for damages or any other
relief, each party shall have the right to pursue such injunctive relief in
court, rather than by arbitration. The parties agree that such action for a
temporary restraining order, a preliminary or temporary injunction, or other
injunctive relief will be brought in the State or federal courts residing in
Houston, Harris County, Texas.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    

| | 14.2 | The Company shall pay all costs and expenses of Company and Employee (including,
but not limited to, attorneys fees, the fees of the arbitrator and the AAA
and any other related costs) for any arbitration proceeding or legal action;
provided, however, that if in any such arbitration proceeding or legal action,
the arbitrator or court, respectively, determines that Employee has prosecuted
or defended any issue in such proceeding or action in bad faith, the arbitrator
or court, respectively, may allocate the portion of such costs and expenses
relating to such issue between the parties in any other manner deemed fair,
equitable and reasonable by the arbitrator or court, respectively.

15.      Foreign Corrupt Practices Act.

| | Employee
shall at all times comply with the United States Foreign Corrupt Practices Act,
generally codified in 15 USC 78 (FCPA), as the FCPA may hereafter be amended,
and/or its successor statutes. If Employee pleads guilty to or nolo contendere
or admits civil or criminal liability under the FCPA, or if a court finds that
Employee committed an action resulting in any Company entity having civil or
criminal liability or responsibility under the FCPA with knowledge of the
activities giving rise to such liability or knowledge of facts from which
Employee should have reasonably inferred the activities giving rise to liability
had occurred or were likely to occur, such action or finding shall constitute
Cause for termination by Company under paragraph 3.5 of this Agreement unless
Companys Board of Directors determines that the actions found to be in
violation of the FCPA were taken in good faith and in compliance with all
applicable policies of Company.
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

employment relationship and/or of this Agreement for the periods stated therein.
The provisions of paragraph 14 relating to arbitration shall survive any
termination of the employment relationship between Employee and Company and the
termination of this Agreement. Amounts, compensation, rights and benefits which
Employee is entitled to receive or have accrued to Employee under this Agreement
or under any plan, program, arrangement, agreement or policy of or with Company
or any of its affiliates before, at or subsequent to the termination of the
employment relationship between Employee and Company or the termination of this
Agreement shall not be superseded and shall survive any such termination.

17.      Certain Additional Payments by Company.

| | 17.1 | Anything in this Agreement to the contrary notwithstanding, in the event it
shall be determined that any payment or distribution by Company or any of its
affiliates to or for the benefit of Employee, whether paid or payable or
distributed or distributable pursuant to the terms of this Agreement or
otherwise (any such payments or distributions being individually referred to
herein as a Payment, and any two or more of such payments or
distributions being referred to herein as Payments), would be
subject to the excise tax imposed by Section 4999 of the Internal Revenue Code
of 1986, as amended (the Code) (such excise tax, together with any
interest thereon, any penalties, additions to tax, or additional amounts with
respect to such excise tax, and any interest in respect of such penalties,
additions to tax or additional amounts, being collectively referred herein to as
the Excise Tax), then Employee shall be entitled to receive an
additional payment or payments (individually referred to herein as a
Gross-Up Payment and any two or more of such additional payments
being referred to herein as Gross-Up Payments) in an amount such

| | 17.2 | Subject to the provisions of paragraph 17.3 through 17.11, any determination
(individually, a Determination) required to be made under this
paragraph 17, including whether a Gross-Up Payment is required and the amount of
such Gross-Up Payment, shall initially be made, at Companys expense, by
nationally recognized tax counsel mutually acceptable to Company and Employee
(Tax Counsel). Tax Counsel shall provide detailed supporting legal
authorities, calculations, and documentation both to Company and Employee within
15 business days of the termination of Employees employment, if
applicable, or such other time or times as is reasonably requested by Company or
Employee. If Tax Counsel makes the initial Determination that no Excise Tax is
payable by Employee with respect to a Payment or Payments, it shall furnish
Employee with an opinion reasonably acceptable to Employee that no Excise Tax
will be imposed with respect to any such Payment or Payments. Employee shall
have the right to dispute any Determination (a Dispute) within 15
business days after delivery of Tax Counsels opinion with respect to such
Determination. The Gross-Up Payment, if any, as determined pursuant to such
Determination shall be paid by Company to Employee within five business days of
Employees receipt of such Determination. The existence of a Dispute shall
not in any way affect Employees right to receive the Gross-Up Payment in
accordance with such Determination. If there is no Dispute, such Determination
shall be binding, final and conclusive upon Company and Employee, subject in all
respects, however, to the provisions of paragraph 17.3 through 17.11 below. As a
result of the uncertainty in the application of Sections 4999 and 280G of the
Code, it is possible that Gross-Up Payments (or portions thereof) which will not
have been made by Company should have been made (Underpayment), and
if upon any reasonable written request from Employee or Company to Tax Counsel,
or upon Tax Counsels own initiative, Tax Counsel, at Companys
expense, thereafter determines that Employee is required to make a payment of
any Excise Tax or any additional Excise Tax, as the case may be, Tax Counsel
shall, at Companys expense, determine the amount of the Underpayment that
has occurred and any such Underpayment shall be promptly paid by Company to
Employee.
| | 17.3 | Company shall defend, hold harmless, and indemnify Employee on a fully
grossed-up after tax basis from and against any and all claims, losses,
liabilities, obligations, damages, impositions, assessments, demands,
judgements, settlements, costs and expenses (including reasonable
attorneys, accountants, and experts fees and expenses) with
respect to any tax liability of Employee resulting from any Final Determination
(as defined in paragraph 17.10) that any Payment is subject to the Excise Tax.

| | 17.7  | If, after actual receipt by Employee of an amount of a tax claimed (pursuant to
an Employee Claim) that has been advanced by Company pursuant to paragraph
17.5.2 hereof, the extent of the liability of Company hereunder with respect to
such tax claimed has been established by a Final Determination, Employee shall
promptly pay or cause to be paid to Company any refund actually received by, or

interest paid or credited thereon by the taxing authority and any recovery of
legal fees from such taxing authority related thereto), except to the extent
that any amounts are then due and payable by Company to Employee, whether under
the provisions of this Agreement or otherwise. If, after the receipt by Employee
of an amount advanced by Company pursuant to paragraph 17.5.2, a determination
is made by the Internal Revenue Service or other appropriate taxing authority
that Employee shall not be entitled to any refund with respect to such tax
claimed and Company does not notify Employee in writing of its intent to contest
such denial of refund prior to the expiration of 30 days after such

any time thereafter have the right (but not the obligation), at his election and
in his sole and absolute discretion, to defend or prosecute, at the sole cost,
expense and risk of Company, such Employee Claim. Employee shall have full
control of such defense or prosecution and such proceedings, including any
settlement or compromise thereof. If requested by Employee, Company shall

Employee and his authorized representatives in order to contest effectively such
Employee Claim. Company may attend, but not participate in or control, any
defense, prosecution, settlement or compromise of any Employee Claim controlled
by Employee pursuant to this paragraph 17.8 and shall bear its own costs and
expenses with respect thereto. In the case of any Employee Claim that is
defended or prosecuted by Employee, Employee shall, from time to time, be
entitled to current payment, on a fully grossed-up after tax basis, from Company
with respect to costs and expenses incurred by Employee in connection with such
defense or prosecution.

from or incurred in connection with such Employee Claim at least ten calendar
days before the date payment of such taxes is due from Employee, except where
payment of such taxes is sooner required under the provisions of this paragraph
17.9, in which case payment of such taxes (and payment, on a fully grossed-up
after tax basis, of any costs and expenses required to be paid under this
paragraph 17.9 shall be made within the time and in the manner otherwise
provided in this paragraph 17.9.

termination of this Agreement by Employee under paragraph 3.1 shall not, for
purposes of this paragraph 20, constitute voluntary termination without Good
Reason by Employee).

| | 20.2 | Employee understands that the foregoing restrictions may limit Employees
ability to engage in certain businesses anywhere in the world during the period
provided for above, but acknowledges that Employee will receive sufficiently
high enumeration and other benefits under this Agreement to justify such
restriction. Employee acknowledges that money damages would not be sufficient
remedy for any breach of this Article by Employee, and Company shall be entitled
to enforce the provisions of this Agreement and/or to specific performances and
injunctive relief as remedies for such breach or any threatened breach. Such
remedies shall not be deemed the exclusive remedies for a breach of this
Article, but shall be in addition to all remedies available at law or in equity
to Company, including, without limitation, the recovery of damages from Employee
and Employees agents involved in such breach and remedies available to
Company pursuant to other agreements with Employee.
| | 20.3 | It is expressly understood and agreed that Company and Employee consider the
restrictions contained in this paragraph 20 to be reasonable and necessary.
Nevertheless, if any of the aforesaid restrictions are found by a court having
jurisdiction to be unreasonable, or overly broad as to geographic area or time,
or otherwise unenforceable, the parties intend for the restrictions therein set
forth to be modified by such courts so as to be reasonable and enforceable and,
as so modified by the court, to be fully enforced.
