                --------------------------------


     THIS SEPARATION AGREEMENT AND RELEASE ("Agreement") is made
and entered into this 31st day of March, 1999, by and between
WILLBROS USA, INC. ("Employer") and M. KIETH PHILLIPS ("Employee").
     
                          WITNESSETH:
                          -----------

     WHEREAS, Employee is currently employed by Employer; and
     
     WHEREAS, Employee will retire from his employment with
Employer effective March 31, 1999 ("Retirement Date"); and
     
     WHEREAS, Employer and Employee wish to achieve a final and
amicable resolution of all issues related to their employment
relationship;
     
     NOW, THEREFORE, for and in consideration of the mutual
covenants and promises set forth below, as well as other good and
valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties agree as follows:
     
1.   Employee's Retirement.  Employee and Employer confirm and
     ---------------------
     agree that Employee is retiring from employment with Employer as
     of the Retirement Date and that the employment relationship which
     existed between Employee and Employer and/or any of Employer's
     affiliated companies shall cease as of the Retirement Date.
     However, nothing contained herein, shall prevent or interfere
     with the ability of the parties to enter into future agreements
     for Employee to provide consulting services and advice to
     Employer or Employer's affiliates on an independent contractor
     basis ("Subsequent Agreement").  Except as provided in any
     Subsequent Agreement, all of Employer's obligations to Employee
     on or after the Retirement Date are set forth herein.
     Accordingly, except as otherwise provided herein or in a
     Subsequent Agreement, Employer shall have no further obligations
     whatsoever to Employee after the Retirement Date.  Similarly,
     except as provided in any Subsequent Agreement, all of Employee's
     obligations to Employer on or after the Retirement Date are set
     forth herein. Accordingly, except as otherwise provided herein or
     in a Subsequent Agreement, Employee shall have no further
     obligations to Employer after the Retirement Date.  Employer
     shall cause its personnel records to reflect that Employee
     retired from employment with Employer effective on the Retirement
     Date.

2.   Prior Agreements Superseded.  Except as otherwise
     ---------------------------
     specifically provided herein, this Agreement supersedes and
     replaces all other prior agreements, written or oral, relating to
     Employee's employment with Employer and/or any of Employer's
     affiliated companies.

3.   Management Incentive Plan.  Prior to the Retirement Date,
     -------------------------
     Employee participated in the Willbros USA, Inc. Management
     Incentive Plan dated January 1, 1996 ("Incentive Plan").

                            





     Employee acknowledges that the Incentive Plan terminated
     December 31, 1998 and that Employee is not entitled to any
     further payments or benefits under the Incentive Plan.

4.   Medical Insurance Continuation.  After the Retirement Date,
     ------------------------------
     Employee and Employee's spouse will be entitled to continue group
     medical coverage under Employer's Retiree Medical Plan ("Retiree
     Medical Plan").  Employer reserves the right, pursuant to the
     terms of its Retiree Medical Plan, to amend or terminate any or
     all provisions of the Retiree Medical Plan in the future.  If
     Employee is not entitled to Medicare benefits and does not elect
     coverage under the Retiree Medical Plan, Employee will be
     entitled to continue participation for a limited period of time
     in Employer's Group Medical Plan, Group Dental Plan and/or
     Executive Medical Plan under the Consolidated Omnibus Budget
     Reconciliation Act of 1985 ("COBRA").  Detailed information
     concerning the costs and procedures applicable to such alternate
     insurance coverage will be provided separately by Employer.

5.   Life Insurance Conversion.  Employee has the right to
     -------------------------
     convert Employee's life insurance coverage under Employer's Group
     Life Plan and dependent life insurance coverage obtained by the
     Employee under Employer's Dependent Life Plan to individual life
     insurance policies. Conversion forms and premium rates applicable
     to such conversion programs will be provided separately by the
     relevant insurer.

6.   Pension Plan.  As a vested participant in the Willbros USA,
     ------------
     Inc. Pension Plan ("Pension Plan") maintained by Employer for the
     benefit of eligible employees, Employee is or will become
     entitled to certain retirement benefits.  Nothing contained in
     this Agreement shall affect Employee's rights to such benefits as
     provided by the terms of the Pension Plan.  Employee acknowledges
     that Employer has separately provided Employee a specific
     description of Employee's payment options under the Pension Plan.

7.   Executive Benefit Restoration Plan.  In addition to the
     ----------------------------------
     Pension Plan, Employee also participated prior to the Retirement
     Date in the Willbros USA, Inc. Executive Benefit Restoration Plan
     ("Restoration Plan").  On the Retirement Date, Employee shall
     receive Two Hundred Thirty Four Thousand Fifteen U.S. Dollars
     (U.S. $234,015), less applicable payroll tax withholding, under
     the Restoration Plan as a lump sum payment of all accumulated
     benefits due Employee under the Restoration Plan as of the
     Retirement Date.  Effective upon receipt of such payment,
     Employee releases the Employer, the Restoration Plan Trust, the
     Restoration Plan Trustee, and the Restoration Plan administrators
     from any further claims for benefits under the Restoration Plan.

8.   Incentive Stock Options.  Employee is vested in certain
     -----------------------
     incentive stock options and certain non-qualified stock options
     provided by Employer's parent company, Willbros Group, Inc.
     ("WGI") pursuant to the Willbros Group, Inc. 1996 Stock Plan
     ("Stock Plan").  Except as otherwise provided in this Paragraph 9,
     nothing in this Agreement shall affect any rights or
     obligations of Employee or WGI under the Incentive Stock Option
     Agreement or the Non-Qualified Stock Option Agreements entered
     into between Employee and WGI pursuant to


                                   2 





     the Stock Plan.  Employer hereby confirms that WGI has
     accelerated the vesting of certain stock options previously
     awarded to Employee under the Plan with the effect that
     the portions of Employee's previous stock option awards
     pursuant to the Stock Plan which are otherwise not vested
     as of March 31, 1999 will be deemed to be fully vested
     as of that date. Employee acknowledges that any of Employee's
     incentive stock options awarded under the Stock Plan which
     are exercised more than three (3) months after the Retirement
     Date will be treated as non-qualified stock options for 
     U.S. federal income tax purposes.

9.   Employer Stock Ownership Plans.  Employee is indebted to
     ------------------------------
     Employer pursuant to certain secured promissory notes issued to
     Employer by Employee in connection with Employee's purchase of
     stock pursuant to the Willbros USA, Inc. 1992 Employee Non-
     Qualified Stock Ownership Plan and the Willbros USA, Inc. 1996
     Management Personnel Non-Qualified Stock Ownership Plan.
     Employee's obligations and Employer's rights under such
     promissory notes shall not be affected by this Agreement, except
     that Employer waives its rights to accelerate the due dates of
     such promissory notes on account of Employee's retirement.

10.  Employer Investment Plan.  Employee is fully vested in
     ------------------------
     Employer's 401(k) Investment Plan ("Investment Plan").  Employee
     has the option of receiving a lump-sum distribution of Employee's
     total account balance in the Investment Plan, transferring such
     account balance to another tax-qualified plan or to an Individual
     Retirement Account or leaving such account balance in the
     Investment Plan.  Election forms and detailed information
     concerning Employee's options with respect to Employee's account
     balance in the Investment Plan will be provided separately by
     Employer.

11.  Director and Officer Matters.  Nothing in this Agreement
     ----------------------------
     shall affect any of Employee's rights or obligations with respect
     to indemnification or director and officer liability insurance
     coverage to which Employee is entitled or subject in his capacity
     as a former director and officer of Employer, WGI and certain of
     their affiliates, whether under that certain Indemnification
     Agreement between WGI and Employee dated May 2, 1997, or
     otherwise.

12.  Accrued Vacation Pay.  On the Retirement Date, Employee
     --------------------
     shall receive Thirty Six Thousand Seven Hundred Sixty Six U.S.
     Dollars (U.S.$36,766), less applicable payroll tax withholding,
     as compensation for all of Employee's accrued vacation time
     through the Retirement Date.

13.  Other Benefits.  Except as specifically set forth herein,
     --------------
     all employment benefits previously made available to Employee by
     Employer or any of its affiliates, including, without limitation,
     those made available under Employer's Executive Compensation
     Program, shall cease to be available to Employee as of the
     Retirement Date.  Employee acknowledges that he is not entitled
     to receive any compensation, severance payment or retirement
     enhancement payment under the Employer's 1999 Reduction-In-Force
     Plan or WGI's Severance Protection Plan.

                                  3





14.  Lump Sum Payment.  On the Retirement Date, Employer shall
     ----------------
     pay to Employee a lump sum amount of One Hundred Ninety Three
     Thousand Dollars (U. S. $193,000), less applicable payroll tax
     withholding, in consideration of the release specified below and
     the acknowledgements, waivers, representations and undertakings
     specified herein.

15.  Release.  Except for the obligations of Employer specifically
     -------
     set forth or referenced in this Agreement, Employee fully and
     forever relieves, releases, and discharges Employer, WGI and
     all of their respective representatives, officers, directors,
     shareholders, predecessors, successors, parents, subsidiaries,
     operating units, affiliates, divisions, employees and attorneys
     from any and all claims, debts, liabilities, demands,
     obligations, promises, acts, agreements, costs, expenses,
     damages, actions, and causes of action, whether in law or in
     equity, whether known or unknown, suspected or unsuspected,
     arising from Employee's employment with and termination from
     Employer, including but not limited to any and all claims
     pursuant to Title VII of the Civil Rights Act of 1964, 42 U.S.C.
     Section 2000e, et seq., as amended by the Civil Rights Act of
     1991, which prohibits discrimination in employment based on race,
     color, national origin, religion or sex; the Civil Rights Act of
     1966, 42 U.S.C. Sections 1981, 1983 and 1985, which prohibits
     violations of civil rights; the Age Discrimination in Employment
     Act of 1967, as amended, and as further amended by the Older
     Workers Benefit Protection Act, 29 U.S.C. Section 621, et seq.,
     which prohibits age discrimination in employment; the Employment
     Retirement Income Security Act of 1974, as amended, 29 U.S.C.
     Section 1001, et seq., which protects certain employee benefits;
     the Americans with Disabilities Act of 1990, as amended, 42
     U.S.C. Section 12101, et seq., which prohibits discrimination
     against the disabled; the Family and Medical Leave Act of 1993,
     29 U.S.C. Section 2601, et seq., which provides medical and

     et seq., including the Wage and Hour Laws relating to
     payment of wages; 85 O.S. 1991 Sections 5, 6 and 7, which
     prohibits discharge in retaliation for exercising rights under
     Oklahoma's Workers' Compensation Act; and all other federal,
     state or local laws or regulations prohibiting employment
     discrimination.  This release also includes, but is not limited
     to, a release by Employee of any claims for breach of contract,
     mental pain, suffering and anguish, emotional upset, impairment
     of economic opportunities, unlawful interference with employment
     rights, defamation, intentional or negligent infliction of
     emotional distress, fraud, wrongful termination, wrongful
     discharge in violation of public policy, breach of any express or
     implied covenant of good faith and fair dealing, that Employer
     has dealt with Employee unfairly or in bad faith, and all other
     common law contract and tort claims.  Employee is not waiving any
     rights or claims that may arise after the Retirement Date.

16.  Confidentiality.  For a period of five (5) years after the
     ---------------
     Retirement Date, Employee shall not, except as otherwise required
     by law, furnish, disclose or make accessible to any person,
     entity or government authority, any knowledge, trade secrets,
     customer information, supplier information, plans, opportunities,
     procedures, data, techniques or other information relating to the
     businesses or finances of Employer or any of its affiliates.  The
     prohibitions of this Paragraph 16 shall not apply, however, to
     information in the public domain (but only if the

                                     4





     same becomes part of the public domain through a means other
     than a disclosure prohibited hereunder).

17.  Remedies.  The parties recognize that, because of the nature
     --------
     of the subject matter of Paragraph 16 above, it would be
     impracticable and extremely difficult to determine the actual
     damages suffered by Employer in the event of a material breach of
     Employee's obligations thereunder.  Accordingly, if Employee
     commits a material breach, or threatens to commit a material
     breach, of any of the provisions of Paragraph 16, Employer or any
     of its successors or assigns shall give Employee written notice
     of such violation and, if Employee has not cured such violation
     or otherwise ceased to act in violation of Paragraph 16 within
     ten (10) days after the giving of such notice, Employer or any of
     its successors or assigns shall have the following rights and
     remedies:

     (a)  to have the provisions of Paragraph 16 specifically
          enforced by any court having equity jurisdiction,
          without the posting of bond or other security, it
          being acknowledged and agreed by Employee that any
          such breach or threatened breach will cause
          irreparable injury to Employer and that an injunction
          may be issued against Employee to stop or prevent any
          such breach or threatened breach; and

     (b)  to recover such actual damages as Employer or its
          affiliates may incur as a result of such breach or
          threatened breach.
     
     The curing of a violation of the requirements of Paragraph 16
     shall not preclude Employer from seeking the recovery of
     its actual damages resulting from such violation.
     
18.  Independent Legal Advice.  Employee acknowledges that he has
     ------------------------
     been represented by independent legal counsel of his choice with
     respect to the advisability of signing this Agreement and
     providing the releases, waivers, acknowledgements,
     representations and undertakings specified herein, and with
     respect to his rights and obligations under the terms of this
     Agreement.

19.  Knowledge of Contents.  Both parties acknowledge that they
     ---------------------
     have carefully read this Agreement and that the contents hereof
     are known and understood by them.  This Agreement is signed
     freely by each party hereto.

20.  Review and Revocation Period.  Employee acknowledges that he
     ----------------------------
     has been extended a period of twenty-one (21) days within which
     to consider this Agreement.  For a period of seven (7) days
     following Employee's execution of the Agreement, Employee may
     revoke this Agreement by notifying Employer, in writing, of his
     desire to do so.  After the seven (7) day period has elapsed,
     this Agreement shall be binding and enforceable.

21.  Obligation to Return Funds.  In the event Employee exercises
     --------------------------
     his right to revocation set forth in Section 20 above, Employee
     shall immediately return to Employer all amounts paid


                                  5






     to Employee as consideration under this Agreement.  The
     duty to return funds under this Agreement shall survive the
     revocation of the Agreement and shall constitute a separately
     enforceable obligation between Employee and Employer.

22.  No Admission of Liability.  This Agreement and compliance
     -------------------------
     with this Agreement shall not be construed as an admission by
     Employer or Employee of any liability whatsoever, or as an
     admission by Employer of any violation of the rights of Employee
     or any other person, or any violation of any order, law, statute,
     duty or contract.

23.  Severability.  In the event that any provision of this
     ------------
     Agreement should be held to be void, voidable, or unenforceable,
     the remaining portions hereof shall remain in full force and
     effect.

24.  Governing Law.  This Agreement will be interpreted and
     -------------
     enforced in accordance with the laws of the State of Oklahoma.

25.  Entirety and Integration.  Upon the execution hereof by all
     ------------------------
     of the parties hereto, this Agreement shall constitute a single,
     integrated contract expressing the entire agreement of the
     parties relative to the subject matter hereof and supersedes all
     prior negotiations, understandings and/or agreements, if any, of
     the parties.  No covenants, agreements, representations, or
     warranties of any kind whatsoever have been made by any party
     hereto, except as specifically set forth in this Agreement.

     IN WITNESS WHEREOF, the parties hereto have executed this
Agreement on the date first mentioned above.
