                          INDEPENDENT AUDITORS' REPORT



Willbros Employees' Benefits Committee
Willbros USA, Inc.:


We have audited the accompanying statements of net assets available for plan
benefits of Willbros Employees' 401(k) Investment Plan as of December 31, 2001
and 2000, and the related statements of changes in net assets available for plan
benefits for the years then ended. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for plan benefits of Willbros
Employees' 401(k) Investment Plan as of December 31, 2001 and 2000, and the
changes in net assets available for plan benefits for the years then ended in
conformity with accounting principles generally accepted in the United States of
America.

Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental information included in
schedule 1 is presented for purposes of additional analysis and is not a
required part of the basic financial statements but is supplemental information
required by the Department of Labor's Rules and Regulations for Reporting and
Disclosure under the Employee Retirement Income Security Act of 1974. The
supplemental schedule is the responsibility of the Plan's management. Such
information has been subjected to the auditing procedures applied in the audits
of the basic financial statements and, in our opinion, is fairly stated in all
material respects in relation to the basic financial statements taken as a
whole.

                   WILLBROS EMPLOYEES' 401(K) INVESTMENT PLAN

                          Notes to Financial Statements

                           December 31, 2001 and 2000


(1)    DESCRIPTION OF PLAN

       The following description of the Willbros Employees' 401(k) Investment
       Plan (the Plan) provides only general information. Participants should
       refer to the Plan document for a more complete description of the Plan's
       provisions.

       (a)    GENERAL

              The Plan is a defined contribution plan covering all full-time
              employees of Willbros USA, Inc., Willbros Engineers, Inc.,
              Willbros Operating Services, Inc. and Rogers and Phillips, Inc.,
              and all salaried employees of Willbros Energy Services Company
              (collectively, the Company) who have one year of eligible service.
              It is subject to the provisions of the Employee Retirement Income
              Security Act of 1974, as amended (ERISA).

       (b)    CONTRIBUTIONS

              Participants may contribute, by payroll deductions, from 1% to 20%
              of their compensation to the Plan and allocate these amounts as
              deferred or taxable contributions. The Company matches employee
              contributions, up to a maximum of 4% of salary as follows: 100% in
              the form of cash or 125% in the form of Willbros Group, Inc.
              common stock, as elected by the employee.

       (c)    PARTICIPANT ACCOUNTS

              Each participant's account is credited with the participant's
              contributions and the Company contributions. At each valuation
              date, participants' accounts for each investment option are
              credited with their share of the net income and gains and charged
              with losses. The benefit to which a participant is entitled is the
              benefit that can be provided from the participant's vested
              account.

       (d)    VESTING

              Participants are immediately vested in their voluntary
              contribution account and their salary reduction account plus
              actual earnings thereon. Vesting in the Company contribution
              account is based on years of service earned as follows: one year -
              25%; two years - 50%; three years - 75%; four years - 100%.

       (e)    FORFEITURES

              The portion of a participant's employer contribution that is
              forfeited because of termination of employment before full vesting
              is applied to reduce the Company's future contributions or pay for
              plan expenses.

       (f)    PAYMENT OF PLAN BENEFITS

              On termination of service, participants may elect to receive a
              lump-sum amount equal to the vested value of their accounts, or,
              if vested plan benefits exceed $5,000, defer distribution until
              age 70 is reached or death occurs.

              Participants who are age 55 may also withdraw their salary
              reduction accounts. Hardship withdrawals from salary reduction
              accounts before age 59-1/2 are also permitted under certain
              circumstances.

       (g)    PARTICIPANT LOANS

              Participants may borrow from the Plan pursuant to Section
              408(b)(1) of ERISA. Loans to a participant may not exceed the
              lesser of 50% of the present value of the nonforfeitable accrued
              benefit of the participant, the balance of the participant's
              voluntary and salary reduction contribution accounts plus the
              vested portion of his or her Company contribution account, or
              $50,000. The minimum loan is $1,000.

              Loans are stated at cost, which approximates fair value.

              Administrative expenses of the Plan (except transaction fees for
              participants' specifically directed investments and trustee fees)
              are paid by the Company.

(2)    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

       (a)    BASIS OF PRESENTATION

              The accompanying financial statements of the Plan have been
              prepared on an accrual basis. The preparation of financial
              statements in conformity with accounting principles generally
              accepted in the United States of America requires management to
              make estimates and assumptions that affect the reported amounts of
              net assets available for plan benefits and changes in net assets
              available for plan benefits during the reporting period. Actual
              results could differ from those estimates.

                           December 31, 2001 and 2000


       (b)    NET ASSETS AVAILABLE FOR PLAN BENEFITS

              Net assets available for plan benefits include benefits payable to
              current participants and those who have withdrawn from the Plan.
              The annual information return filed with the Internal Revenue
              Service (Form 5500) requires amounts due to participants who have
              withdrawn from the Plan to be stated as a liability and a
              distribution. There were no such benefits payable at December 31,
              2001 and 2000.

       (c)    INVESTMENTS

              Investments are held in pooled trust funds and mutual funds and
              are stated at the Plan's proportionate share of the fair value of
              the holdings of the pooled trust funds. If available, quoted
              market prices are used to value investments in mutual funds and
              other securities. The difference between the current value and the
              historical cost is reflected as net appreciation or depreciation.
              Purchases and sales of investments are recorded on a trade date
              basis.

 (3)   PLAN TERMINATION

       Although it has not expressed any intent to do so, the Company has the
       right under the Plan to discontinue its contributions at any time and to
       terminate the Plan subject to the provisions of ERISA. In the event of
       plan termination, participants will become 100% vested in their accounts.

(4)    TAX STATUS

       The Plan was established January 1, 1976 under the provisions of ERISA.
       The Internal Revenue Service has determined that the Plan is qualified
       under Section 401(a) and 401(k) of the Internal Revenue Code (IRC) and
       that the Plan is exempt from Federal income taxes under Section 501(a)
       which provides that earned income is taxable only upon distribution
       thereof. A favorable determination letter covering the Plan has been
       received from the Internal Revenue Service. The Plan has been amended
       since receiving the determination letter. However, management believes
       that the Plan is designed and is currently operated within the applicable
       requirements of the IRC.

(5)    INVESTMENTS

       The Plan's investments and cash are held by Bank of Oklahoma, N.A. and
       administered under a trust agreement with the Company. The Plan's
       investment options are managed by Frank Russell Trust Company (FRTC),
       which has full discretionary authority for purchase and sale of
       investments not specifically directed by participants within the approved
       Plan options; however, the Willbros Employees' Benefits Committee retains
       the right to change the options available to participants.

       Effective April 1, 2001, the Plan was amended to allow employees to
       participate after 90 days of service without regard to age of the
       employee. Vesting in the Company contribution account is based on years
       of service earned as follows: one to two years - 25%; two to three years
       - 50%; three to four years 75%; and over four years - 100%.
