                          INDEPENDENT AUDITORS' REPORT

Willbros Employee 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, 2000
and 1999 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, 2000 and 1999 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.

                          Notes to Financial Statements

                           December 31, 2000 and 1999

(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.

       GENERAL

       The Plan is a defined contribution plan covering all full-time
       employees of Willbros USA, Inc., Willbros Engineers, 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).

       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.

       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.

       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: 3 years - 50%; 4 years - 75%; and 5 years - 100%.

       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.

       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.

                           December 31, 2000 and 1999

       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.

       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.

       INVESTMENT OPTIONS

       Participants may direct investment of their funds to one or more of the
       following investment options:

                          Specifically Directed Investments
                          Specifically Directed Flexible Choice Investments
                          The Frank Russell Investment Contract Fund

       ADMINISTRATIVE EXPENSES

       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

       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.

                          Notes to Financial Statements

                           December 31, 2000 and 1999

       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, 2000 and 1999.

       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 and depreciation. Purchases and sales of investments
       are recorded on a trade date basis.

       NEWLY ISSUED ACCOUNTING PRONOUNCEMENTS

       In September 1999, the American Institute of Certified Public Accountants
       issued Statement of Position 99-3, Accounting for and Reporting of
       Certain Defined Contribution Plan Investments and Other Disclosure
       Matters (SOP 99-3). SOP 99-3 simplifies the disclosure for certain
       investments and is effective for plan years ending after December 15,
       1999. The Plan adopted SOP 99-3 during the Plan year ended December 31,
       1999. Accordingly, information previously required to be disclosed about
       participant-directed fund investment programs is not presented in the
       Plan's 2000 or 1999 financial statements.

(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 Sections 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 Employee Benefits Committee retains
       the right to change the options available to participants.

       The following table presents the fair values of investments at December
       31, 2000 and 1999. Investments that represent 5% or more of the Plan's
