                       FOR ANNUAL MEETING OF STOCKHOLDERS
                             TO BE HELD MAY 20, 2004

                     SOLICITATION AND REVOCATION OF PROXIES

      This Proxy Statement is furnished in connection with the solicitation by
the Board of Directors of Willbros Group, Inc., a Republic of Panama corporation
(the "Company"), of proxies to be voted at the Annual Meeting of Stockholders of
the Company to be held on May 20, 2004, or at any adjournment thereof (the
"Annual Meeting"), for the purposes set forth in the accompanying Notice of
Annual Meeting. This Proxy Statement and accompanying proxy were first sent on
or about April 23, 2004, to stockholders of record on April 22, 2004.

      If the accompanying proxy is properly executed and returned, the shares
represented by the proxy will be voted at the Annual Meeting. If a stockholder
indicates in his or her proxy a choice with respect to any matter to be acted
upon, that stockholder's shares will be voted in accordance with such choice. If
no choice is indicated, such shares will be voted "FOR" (a) the election of all
of the nominees for directors listed below, (b) the approval of the amendment to
the Willbros Group, Inc. 1996 Stock Plan, and (c) the ratification of the
appointment of the independent auditors. A stockholder giving a proxy may revoke
it by giving written notice of revocation to the Secretary of the Company at any
time before it is voted, by executing another valid proxy bearing a later date
and delivering such proxy to the Secretary of the Company prior to or at the
Annual Meeting, or by attending the Annual Meeting and voting in person.

      The expenses of this proxy solicitation, including the cost of preparing
and mailing this Proxy Statement and accompanying proxy, will be borne by the
Company. Such expenses will also include the charges and expenses of banks,
brokerage firms and other custodians, nominees or fiduciaries for forwarding
solicitation material regarding the Annual Meeting to beneficial owners of the
Company's Common Stock. Solicitation of proxies may be made by mail, telephone,
personal interviews or by other means by the Board of Directors or employees of
the Company who will not be additionally compensated therefor, but who may be
reimbursed for their out-of-pocket expenses in connection therewith.

                          STOCKHOLDERS ENTITLED TO VOTE

      Stockholders of record at the close of business on April 22, 2004, will be
entitled to vote at the Annual Meeting. As of March 31, 2004, there were issued
and outstanding 21,020,638 shares of Common Stock, par value $.05 per share of
the Company (the "Common Stock"). Each share of Common Stock is entitled to one
vote. There is no cumulative voting with respect to the election of directors.
The presence in person or by proxy of the holders of a majority of the shares
issued and outstanding at the Annual Meeting and entitled to vote will
constitute a quorum for the transaction of business. Votes withheld from
nominees for directors, abstentions and broker non-votes will be counted for
purposes of determining whether a quorum has been reached. Votes will be
tabulated by an inspector of election appointed by the Board of Directors of the
Company. With regard to the election of directors, votes may be cast in favor of
or withheld from each nominee; votes that are withheld will have the effect of a
negative vote. Abstentions, which may be specified on all proposals except the
election of directors, will have the effect of a negative vote. A broker
non-vote will have no effect on the outcome of the election of directors or the
other proposals.




                                  PROPOSAL ONE

                              ELECTION OF DIRECTORS

      The Restated Articles of Incorporation of the Company (the "Charter")
provides that the Board of Directors of the Company (the "Board of Directors")
shall consist of not less than three nor more than fifteen directors, as
determined from time to time by resolution of the Board of Directors. The number
of directors is currently fixed at nine. The Board of Directors is divided into
three approximately equal classes. The terms of such classes are staggered so
that only one class is elected at the annual meeting of stockholders each year
for a three-year term. The term of the current Class II directors will expire at
the Annual Meeting. The terms of the current Class III directors and the current
Class I directors will expire at the annual meetings of stockholders to be held
in 2005 and 2006, respectively.

      In accordance with the recommendation of the Nominating/Corporate
Governance Committee, the Board of Directors has nominated Rodney B. Mitchell
and S. Miller Williams for election as Class II directors. Mr. Mitchell, who
currently serves as a Class II director and whose term expires at the Annual
Meeting, is standing for re-election as a Class II director for a term expiring
at the annual meeting of stockholders in 2007. He was elected to the Board of
Directors in July 2001 and at that time was recommended to the
Nominating/Corporate Governance Committee by the Company's then Chief Executive
Officer. Mr. S. Miller Williams is a new nominee for director and is standing
for election as a Class II director for a term expiring at the annual meeting of
stockholders in 2007. He was recommended to the Nominating/Corporate Governance
Committee by the Company's President and Chief Executive Officer. John H.
Williams, age 85, and Michael J. Pink, age 66, who currently serve as Class II
directors and whose terms expire at the Annual Meeting, are not seeking
re-election as directors as they have elected to retire from the Board of
Directors as of the date of the Annual Meeting. S. Miller Williams is standing
for election to the Board position being vacated by Mr. Pink. S. Miller Williams
is the son of John H. Williams. The Board position being vacated by John H.
Williams will remain vacant. The Charter provides that any Board vacancies may
be filled by the affirmative vote of a majority of the remaining directors. The
Nominating/Corporate Governance Committee and the Board of Directors have not
yet identified anyone to fill the vacancy. Accordingly, the accompanying proxy
solicits your vote for only two directors. The persons named as proxies in the
accompanying proxy, who have been designated by the Board of Directors, intend
to vote, unless otherwise instructed in such proxy, for the election of Messrs.
Mitchell and M. Williams. Should any nominee named herein become unable for any
reason to stand for election as a director of the Company, it is intended that
the persons named in such proxy will vote for the election of such other person
or persons as the Nominating/Corporate Governance Committee may recommend and
the Board of Directors may propose to replace such nominee. The Company knows of
no reason why any of the nominees will be unavailable or unable to serve.

      Guy E. Waldvogel, who has served as a director since 1990, retired from
the Board of Directors on March 10, 2004. S. Fred Isaacs was elected by the
Board of Directors on March 10, 2004, to fill the vacancy on the Board of
Directors created by Mr. Waldvogel's retirement.

      The Company is grateful and appreciative of Messrs. Waldvogel's, Pink's
and J. Williams' many years of dedicated service to the Company and their
valuable counsel and business advice over the years.

      On March 10, 2004, the Board of Directors elected Michael F. Curran as
Chairman of the Board of Directors. Mr. Curran succeeds Larry J. Bump who will
relinquish the Chairman's position at the Annual Meeting and remain a director
for the duration of his term, expiring in 2005. Mr. Curran will continue to
perform his duties as President and Chief Executive Officer.

      The affirmative vote of the holders of a majority of the shares present in
person or by proxy at the Annual Meeting and entitled to vote is required for
the election of directors. The Board of Directors recommends a vote "FOR" each
of the following nominees for directors.

COMPENSATION OF DIRECTORS

      Employee directors receive no additional compensation for service on the
Board of Directors or any committee thereof. Non-employee directors currently
receive an annual retainer of $30,000 plus a fee of $1,500 per meeting for
attending meetings of the Board of Directors. Non-employee directors also
receive fees for attending meetings of committees of the Board of Directors as
follows: chairman of the committee receives $2,500 per meeting and the other
members of the committee receive $1,500 per meeting.

      Non-employee directors automatically receive non-qualified stock options
under the Willbros Group, Inc. Director Stock Plan, as amended (the "Director
Stock Plan"). Under the Director Stock Plan, an initial option to purchase 5,000
shares of Common Stock is granted to each new non-employee director on the date
such director is elected or appointed to the Board of Directors. Each
non-employee director also receives annually an option to purchase 5,000 shares
of Common Stock. Effective January 1, 2004, such annual option is granted on the
second Monday in January of each year during the period of such director's
incumbency. Prior to January 1, 2004, such option was granted on the annual
anniversary of the date on which such director received an initial option, and
on each succeeding annual anniversary of such date during the period of such
director's incumbency. The option exercise price of each option granted under
the Director Stock Plan is equal to the fair market value of the Common Stock on
the date of grant. A total of 225,000 shares of Common Stock is available for
issuance under the Director Stock Plan. During fiscal 2003, Mr. Taylor was
granted an option to purchase 5,000 shares of Common Stock at an exercise price
of $8.20 per share, Mr. Bump was granted an option to purchase 5,000 shares of
Common Stock at an exercise price of $9.63 per share, Mr. Mitchell was granted

and Messrs. Pink and J. Williams were each granted an option to purchase 5,000

been exercised under the Director Stock Plan.

      All directors are reimbursed by the Company for out-of-pocket expenses
incurred by them in connection with their service on the Board of Directors and
any committee thereof.

      The Company paid Mr. Bump $120,000 during 2003 for consulting services
consisting of advice and assistance rendered in connection with its business
activities.

CORPORATE GOVERNANCE AND BOARD MATTERS

      The Board of Directors and corporate management utilize their best
individual efforts to adopt and implement best practices of corporate
governance. Each believes strongly that effective corporate governance practices
underpin its efforts to focus the entire organization on generating long-term
stockholder value through conscientious actions and in an ethical manner. The
directors have a wide range of business


                                       4


and industry experience, which provides insightful perspective on significant
matters and an understanding of the challenges facing the Company. The Company's
commitment to sound, independent oversight is demonstrated by the make-up of the
Board, which has been comprised of a majority of independent directors since the
Company's initial public offering in 1996.

      In 2003, the Board of Directors implemented Corporate Governance
Guidelines, adopted an updated Code of Business Conduct and Ethics, and
established a Code of Ethics for the Chief Executive Officer and Senior
Financial Officers. The Corporate Governance Guidelines and Codes are available
on the Company's website at http://www.willbros.com.

      The Company is committed and dedicated to employing sound, ethical
business practices, complying with the law in all areas of the world in which it
works, and demanding the highest standards of integrity from its employees.
There is common agreement that effective corporate governance requires the
checks and balances provided by a proactive Board of Directors and corporate
management actively engaged with others in the organization.

      BOARD INDEPENDENCE. The Board of Directors has affirmatively determined
that each of Messrs. Isaacs, Leidel, Mitchell, Pink, Taylor and J. Williams,
current directors of the Company, and S. Miller Williams, the new nominee for
director, are "independent" under the current director independence standards of
the New York Stock Exchange. In so doing, the Board of Directors determined that
each of those individuals met the "bright line" independence standards of the
New York Stock Exchange and has no other material relationship with the Company
(either directly or as a partner, stockholder or officer of an organization that
has a relationship with the Company). In making the determination of
independence, the Board of Directors not only used the "bright line"
independence standards of the New York Stock Exchange, but also the standard
that no relationships exist that are required to be reported under the caption
"Certain Transactions" in this Proxy Statement pursuant to the rules and
regulations of the Securities and Exchange Commission. Mr. Bump is not
considered to be independent because of his former employment as a senior
executive officer of the Company and he receives more than $100,000 per year in
consulting fees. Mr. Curran is not considered to be independent because of his
employment as a senior executive officer of the Company.

      MEETINGS AND COMMITTEES OF THE BOARD OF DIRECTORS. During 2003, the Board
of Directors held four meetings. Each director was present at 75% or more of the
aggregate of the meetings of the Board of Directors and of the committees of the
Board of Directors on which he served during 2003.

      Each director is encouraged to participate in annual meetings of
stockholders of the Company. However, since such meetings are held in Panama
City, Panama, are generally of a short duration, and the Board of Directors does
not generally have a meeting coincident with the annual meeting of stockholders,
it is often impractical and expensive for each director to attend in person.
Therefore, participation by either telephone or in person is encouraged. In
addition, as discussed below, the Board of Directors has a process in place by
which stockholders and other interested parties may communicate with the Board
of Directors or any of its directors. Two directors, Messrs. Bump and Curran,
attended the Company's 2003 Annual Meeting of Stockholders.

      The Board of Directors has a standing Executive Committee, Audit
Committee, Compensation Committee and Nominating/Corporate Governance Committee.
Each of the current members of each of the committees, other than the Executive
Committee, qualifies as an "independent" director under the current listing
standards of the New York Stock Exchange.

      Executive Committee. During 2003, the Executive Committee was composed of
Messrs. Curran (Chairman), Bump and J. Williams. The Executive Committee is
authorized to act for the Board of Directors in the management of the business
and affairs of the Company, except with respect to a limited number of matters
which include changing the size of the Board of Directors, filling vacancies on
the Board of Directors, amending the By-laws of the Company, disposing of all or
substantially all of the assets of the Company, and recommending to the
stockholders of the Company an amendment to the Articles of Incorporation of the
Company or a merger or consolidation involving the Company. The Executive
Committee did not meet during 2003.


                                       5



      Audit Committee. During 2003, the Audit Committee was composed of Messrs.
Leidel (Chairman), Mitchell, Taylor, and Waldvogel. The Board of Directors has
determined that it has at least one "audit committee financial expert" serving
on the Audit Committee and that person is Mr. Leidel. The Audit Committee has
adopted a written charter. In 2003, the Audit Committee amended and restated the
Audit Committee Charter to bring it current with the new regulations adopted by
the Securities and Exchange Commission and the New York Stock Exchange. This
charter is attached to this Proxy Statement as Exhibit A and is also available
on the Company's website at http://www.willbros.com. In addition, it adopted a
Procedure of the Audit Committee on Reporting and Investigating Complaints with
Regard to Possible Accounting Irregularities. The Audit Committee recommends to
the full Board of Directors the firm to be appointed each year as independent
auditors of the Company's financial statements and to perform services related
to the completion of such audit. The Audit Committee also has the responsibility
to (a) review the scope and results of the audit with the independent auditors,
(b) review with management and the independent auditors the Company's interim
and year-end financial condition and results of operations, (c) consider the
adequacy of the internal accounting, bookkeeping and other control procedures of
the Company, and (d) review and pre-approve any non-audit services and special
engagements to be performed by the independent auditors and consider the effect
of such performance on the auditors' independence. The Audit Committee also
generally reviews the terms of material transactions and arrangements, if any,
between the Company and its directors, officers and affiliates. The Audit
Committee held eight meetings during 2003.

      Compensation Committee. During 2003, the Compensation Committee was
composed of Messrs. Taylor (Chairman), Mitchell, and Pink. The Compensation
Committee adopted a written charter in 2003. This charter is available on the
Company's website at http://www.willbros.com. The Compensation Committee reviews
and takes final action for and on behalf of the Board of Directors with respect
to compensation, bonus, incentive, and benefit provisions for the officers of
the Company and its subsidiaries, and administers the 1996 Stock Plan. The
Compensation Committee meets at such times as may be deemed necessary by the
Board of Directors or the Compensation Committee. The Compensation Committee
held four meetings during 2003.

      Nominating/Corporate Governance Committee. During 2003, the
Nominating/Corporate Governance Committee was composed of Messrs. J. Williams
(Chairman), Bump, and Leidel. Mr. Bump resigned as a member of this Committee in
March 2004. In 2003, the Nominating/Corporate Governance Committee adopted a
written charter. This charter is available on the Company's website at
http://www.willbros.com. In addition, the Nominating/Corporate Governance
Committee approved and recommended, and the Board of Directors adopted,
Corporate Governance Guidelines. The Nominating/Corporate Governance Committee
is responsible for recommending candidates to fill vacancies on the Board of
Directors as such vacancies occur, as well as the slate of nominees for election
as directors by stockholders at each annual meeting of stockholders. The
Nominating/Corporate Governance Committee has the authority under its charter to
retain a professional search firm to identify candidates. It is also responsible
for developing and recommending to the Board of Directors the Corporate
Governance Guidelines applicable to the Company. Additionally, the
Nominating/Corporate Governance Committee makes recommendations to the Board of
Directors regarding changes in the size of the Board of Directors and recommends
nominees for each committee. The Nominating/Corporate Governance Committee held
two meetings during 2003.

      CONSIDERATION OF DIRECTOR NOMINEES. The Nominating/Corporate Governance
Committee will consider director candidates submitted to it by other directors,
employees and stockholders. In evaluating such nominations, the
Nominating/Corporate Governance Committee seeks to achieve a balance of
knowledge, experience and capability on the Board of Directors and to address
the director qualifications discussed below. Any stockholder nominations
proposed for consideration by the Nominating/Corporate Governance Committee
should include the nominee's name and qualifications for director and should be
addressed to: Corporate Secretary, Willbros Group, Inc., c/o Willbros USA, Inc.,
4400 Post Oak Parkway, Suite 1000, Houston, Texas 77027. In addition, as
described below, the Company's Charter permits stockholders to nominate
directors for consideration at a meeting of stockholders.

      The Nominating/Corporate Governance Committee regularly assesses the
appropriate size of the Board of Directors, and whether any vacancies on the
Board are expected due to retirement or otherwise. In the event that vacancies
are anticipated, or otherwise arise, the Committee considers various potential


                                       6


candidates for director. Candidates may come to the attention of the Committee
through current directors, professional search firms, stockholders or other
persons.

      Once a prospective nominee has been identified, the Committee makes an
initial determination as to whether to conduct a full evaluation of the
candidate. The initial determination focuses on the information provided to the
Committee with the recommendation of the prospective candidate and the
Committee's own knowledge of the candidate, which may be supplemented by
inquiries to the person making the recommendation or others. If the Committee
determines, after consultation with the Chairman of the Board of Directors and
other directors as appropriate, that additional consideration is warranted, it
may request a professional search firm to gather additional information about
the candidate. The Committee then evaluates the candidate against the
qualifications considered by the Committee for director candidates which include
an attained position of leadership in the candidate's field of endeavor,
business and financial experience, demonstrated exercise of sound business
judgment, expertise relevant to the Company's lines of business, and the ability
to serve the interests of all stockholders. The Committee also assesses the
candidate's qualifications as an "independent director" under the current
director independence standards of the New York Stock Exchange. The candidate
must be able to devote the time, energy and attention as may be necessary to
properly discharge his or her responsibilities as a director. As part of this
evaluation, one or more members of the Committee, and others as appropriate,
will interview the candidate. After completing this evaluation, the Committee
makes a recommendation to the full Board of Directors as to the persons who
should be nominated by the Board, and the Board determines the nominees after
considering the recommendation of the Committee.

      The Company's Charter provides that nominations of candidates for election
as directors of the Company may be made at a meeting of stockholders by or at
the direction of the Board of Directors or by any stockholder entitled to vote
at such meeting who complies with the advance notice procedures set forth
therein. These procedures require any stockholder who intends to make a
nomination for director at the meeting to deliver notice of such nomination to
the Secretary of the Company not less than 45 nor more than 90 days before the
meeting. The notice must contain all information about the proposed nominee as
would be required to be included in a proxy statement soliciting proxies for the
election of such nominee, including such nominee's written consent to serve as a
director if so elected. If the Chairman of the meeting determines that a person
is not nominated in accordance with the nomination procedure, such nomination
will be disregarded. The Company expects that the annual meeting of stockholders
to be held each year will be during the early to mid part of May.

      EXECUTIVE SESSIONS. Executive sessions of the non-management directors are
held periodically. The sessions are scheduled and chaired by the chairman of the
Nominating/Corporate Governance Committee. Any non-management director can
request that an additional executive session be scheduled. Executive sessions of
the independent directors only are held at least once a year.

      COMMUNICATIONS WITH THE BOARD OF DIRECTORS. The Board of Directors
provides a process by which stockholders and other interested parties may
communicate with the Board or any of the directors. Stockholders and other
interested parties may send written communications to the Board of Directors or
any of the directors at the following address: Corporate Secretary, Willbros
Group, Inc., c/o Willbros USA, Inc., 4400 Post Oak Parkway, Suite 1000, Houston,
Texas 77027. All communications will be compiled by the Company's Corporate
Secretary and submitted to the Board or the individual director on a periodic
basis.

                                  PROPOSAL TWO

                         APPROVAL OF AMENDMENT NUMBER 4
                           TO THE WILLBROS GROUP, INC.
                                 1996 STOCK PLAN

GENERAL

      Stockholder action at the Annual Meeting will be requested with respect to
the approval of Amendment Number 4 (the "Amendment") to the Willbros Group, Inc.
1996 Stock Plan, as amended (the "1996 Stock


                                       7


Plan"). The sole purpose of the Amendment is to increase the total number of
shares of Common Stock available for issuance under the 1996 Stock Plan from
3,125,000 shares to 4,075,000 shares. As of March 1, 2004, there were 402,588
remaining shares of Common Stock reserved for future grants of awards under the
1996 Stock Plan. If the Amendment to the 1996 Stock Plan is approved by the
stockholders of the Company, the total number of shares of Common Stock reserved
for future grants of awards under the 1996 Stock Plan would be 1,352,588 and
represent approximately 6.5% of the Company's total outstanding shares of Common
Stock on March 1, 2004.

      While the Board of Directors is aware of the potential dilutive effect of
compensatory stock awards, it also recognizes the significant motivations and
performance benefits that are achieved from making such awards. Accordingly, in
determining the number of additional shares sought under the Amendment, the
Compensation Committee of the Board of Directors undertook a study of the 1996
Stock Plan and the Amendment with an internationally recognized global human
resources and compensation consulting firm. The review consisted of collecting
data from peer companies in the engineering/construction and oilfield services
industries on stock plan utilization levels, preparing information from key
published reports dealing with stock compensation, and evaluating the 1996 Stock
Plan features with respect to the market information collected. The study, among
other things, indicated that (a) the Company's utilization rates as a percentage
of shares of Common Stock outstanding, or potential dilutive effects, falls
below the peer group median; (b) the percentage of shares of Common Stock
outstanding utilized annually by the Company for stock-based pay was below the
peer group median in 2002, and was under 1% of shares of Common Stock
outstanding in the Company's January 12, 2004 grant of awards to key employees
under the 1996 Stock Plan; and (c) the request for stockholder approval of
950,000 additional shares being available for issuance under the 1996 Stock Plan
brings the Company, when compared to the peer companies, to the 50th percentile.
The additional shares represent less than 5% of the Company's Common Stock
outstanding as of March 1, 2004.

      A copy of the Amendment is attached hereto as Exhibit B. A copy of the
1996 Stock Plan will be furnished by the Company to any stockholder upon written
request to: Dennis G. Berryhill, Corporate Secretary, Willbros Group, Inc., c/o
Willbros USA, Inc., 4400 Post Oak Parkway, Suite 1000, Houston, Texas 77027. The
Amendment, which was approved by the Board of Directors on March 10, 2004, will
not take effect unless approved by the affirmative vote of the holders of a
majority of the shares of Common Stock present in person or represented by proxy
at the Annual Meeting and entitled to vote.

      The purpose of the 1996 Stock Plan is to strengthen the ability of the
Company to attract and retain well-qualified executive, managerial, and
professional personnel, and to encourage stock ownership by such personnel in
order to increase their proprietary interest in the Company's success. The
Company relies heavily upon stock options and restricted stock awards under the
1996 Stock Plan to compensate its executive, managerial, and professional
personnel, and to retain and motivate such personnel, and desires to continue
that practice because it believes that such awards encourage and reward
effective management that results in long-term corporate financial success, as
measured by stock price appreciation.

SUMMARY OF THE 1996 STOCK PLAN

      General. In 1996, the Board of Directors adopted, and the stockholders of
the Company approved, the Willbros Group, Inc. 1996 Stock Plan. The 1996 Stock
Plan provides for awards to key employees of the Company, including officers and
directors who are also employees of the Company. The 1996 Stock Plan provides
that during any calendar year, no participant may be granted awards with respect
to more than 150,000 shares, subject to certain adjustments. The stock issuable
under the 1996 Stock Plan may be authorized and unissued shares or treasury
shares. If any shares subject to any award are forfeited or payment is made in a
form other than shares or the award otherwise terminates without payment being
made, the shares subject to such awards will again be available for issuance
under the 1996 Stock Plan. In addition, the number of shares deemed to be issued
under the 1996 Stock Plan upon exercise of a stock option will be reduced by the
number of shares surrendered in payment of the exercise or purchase price of
such stock option.

      The 1996 Stock Plan is administered by the Compensation Committee of the
Board of Directors (the "Committee"). The members of the Committee are not
eligible for awards under the 1996 Stock Plan. The Committee is authorized to
determine plan participants, the types and amount of awards to be granted and
the


                                       8


terms, conditions and provisions of awards, prescribe forms of award agreements,
interpret the 1996 Stock Plan, establish, amend and rescind rules and
regulations relating to the 1996 Stock Plan, and make all other determinations
which may be necessary or advisable for the administration of the 1996 Stock
Plan. Although a determination has not been made as to the number of employees
currently eligible for consideration as participants in the 1996 Stock Plan, as
of March 1, 2004, there were 136 employees who held awards under the 1996 Stock
Plan.

      If the Amendment is approved, under the terms of the 1996 Stock Plan, no
more than 1,018,750 shares may be issued under the 1996 Stock Plan pursuant to
awards of restricted stock and/or restricted stock rights.

      Summary of Awards. The 1996 Stock Plan permits the granting of any or all
of the following types of awards: (a) stock options, (b) stock appreciation
rights ("SARs"), and (c) restricted stock or restricted stock rights. Generally,
awards under the 1996 Stock Plan are granted for no consideration other than
prior and future services. Awards granted under the 1996 Stock Plan may, in the
discretion of the Committee, be granted alone or in addition to, in tandem with,
or in substitution for any other award under the 1996 Stock Plan or other plan
of the Company. Such grants could include grants of options after a decline in
the market price of the Company's Common Stock in substitution for previously
granted options having a higher exercise price. The Company, however, has never
"repriced" options previously granted.

      Stock options granted pursuant to the 1996 Stock Plan may, at the
discretion of the Committee, be either incentive stock options ("ISOs"), within
the meaning of Section 422 of the U.S. Internal Revenue Code, or non-qualified
stock options. The exercise price of an ISO may not be less than the fair market
value of the Common Stock on the date of grant (or 110% of such fair market
value in the case of ISOs granted to employees who possess more than 10% of the
combined voting power of all classes of stock of the Company (a "10%
employee")). In the case of non-qualified stock options, the exercise price
shall be as determined by the Committee in its sole discretion, except that it
shall not be less than 85% of the fair market value of the Common Stock on the
date of grant. The Committee, however, does not intend to grant non-qualified
stock options below the fair market value of the Common Stock on the date of
grant. Options granted pursuant to the 1996 Stock Plan are exercisable in whole
or in part at such time or times as determined by the Committee, except that
ISOs may not be exercised after the expiration of 10 years from the date granted
(five years in the case of a 10% employee). Generally, options may be exercised
by the payment of cash, promissory notes or stock or a combination thereof.

      SARs granted under the 1996 Stock Plan will give the holder the right to
receive cash or stock in an amount equal to the difference between the fair
market value of a share of Common Stock on the date of exercise and the grant
price. The grant price of an SAR is determined by the Committee but may not be
less than the fair market value of a share of Common Stock on the date of grant.
Methods of exercise and settlement and other terms of SARs are determined by the
Committee. The Committee has never granted SARs under the 1996 Stock Plan.

      The Committee may award restricted stock, generally consisting of shares
of Common Stock which may not be disposed of by participants until certain
restrictions established by the Committee lapse. Such restrictions may lapse in
whole or in installments as the Committee determines. A participant receiving
restricted stock will have all of the rights of a stockholder of the Company,
including the right to vote the shares and the right to receive any dividends,
unless the Committee otherwise determines. Upon termination of employment during
the restriction period, restricted stock will be forfeited, subject to such
exceptions, if any, as are authorized by the Committee. The Committee, in its
discretion, may also issue restricted stock rights, which represent the right to
receive shares of Common Stock upon vesting. The rights are considered
"restricted" because they are subject to forfeiture and restrictions on transfer
prior to vesting and the related issuance of shares. A participant receiving
restricted stock rights will not be a stockholder of the Company and will not be
entitled to vote or receive dividends, if any, until the rights vest, at which
time the related shares will be issued to the participant.

      Awards generally are not transferable other than by will or the laws of
descent and distribution; however, the Committee may permit the transfer of
awards (other than ISOs and SARs in tandem therewith) for estate planning
purposes. In the event of any change affecting the shares of Common Stock by
reason of


                                       9


any stock dividend or split, recapitalization, merger, consolidation, spin-off,
combination or exchange of shares, or other corporate change or any
distributions to Common Stock holders, the Committee may make such substitution
or adjustment in the aggregate number or kind of shares which may be distributed
under the 1996 Stock Plan and in the number, kind and exercise, grant or
purchase price of shares subject to the outstanding awards granted under the
1996 Stock Plan, or make provisions for a cash payment relating to any award, as
it deems to be appropriate in order to maintain the purpose of the original
grant.

      Amendment to and Termination of the 1996 Stock Plan. The Board of
Directors may amend, alter, suspend, discontinue or terminate the 1996 Stock
Plan without the consent of stockholders or participants, except that
stockholder approval of such action will be sought if such approval is required
by any federal or state law or regulation, to the extent the action is required
to be approved by stockholders in connection with having any outstanding awards
comply with the requirements of Section 162(m) of the U.S. Internal Revenue
Code, or if the Board of Directors in its discretion determines that obtaining
such stockholder approval is advisable. Unless earlier terminated by the Board
of Directors, the 1996 Stock Plan will terminate when no shares remain reserved
and available for issuance, and the Company has no further obligation with
respect to any award granted under the 1996 Stock Plan.

      Change of Control. In the event of a Change of Control of the Company, all
outstanding awards under the 1996 Stock Plan, regardless of any limitations or
restrictions, become fully exercisable and freed of all restrictions. For
purposes of the 1996 Stock Plan, a Change of Control is deemed to have occurred:
(a) upon the acquisition by any person of 20% or more of the Company's
outstanding voting stock; (b) if individuals constituting the Board of
Directors, or those nominated by at least two-thirds of such individuals or
successors nominated by them, cease to constitute a majority of the Board; (c)
upon stockholder approval of a merger, consolidation or similar transaction or
consummation of any such transaction if stockholder approval is not required;
(d) upon approval of a plan of liquidation or the sale or disposition of
substantially all of the Company's assets; or (e) if the Board adopts a
resolution to the effect that a Change of Control has occurred.

      U.S. Federal Income Tax Consequences. The Company believes that under
present U.S. tax laws the following are the U.S. federal income tax consequences
generally arising with respect to awards granted under the 1996 Stock Plan. The
grant of an option or SAR will create no tax consequences for the participant or
the Company. The participant will have no taxable income upon exercising an ISO
(except that the alternative minimum tax may apply) and the Company will receive
no deduction at that time. Upon exercising an option other than an ISO, a
participant will recognize ordinary income equal to the difference between the
exercise price and the fair market value of the stock acquired on the date of
exercise. Upon exercising an SAR, a participant will recognize ordinary income
equal to the cash or the fair market value of the stock received on the date of
exercise. In the case of the exercise of a non-qualified stock option or SAR,
the employer of the participant, if it is a subsidiary of the Company and a U.S.
taxpayer ("U.S. subsidiary employer"), generally will be entitled to a deduction
for the amount recognized as ordinary income by the participant, unless such
deduction is limited by Section 162(m) of the Internal Revenue Code. The
treatment to a participant of a disposition of shares acquired upon the exercise
of an SAR or option depends on how long the shares have been held and on whether
such shares are acquired by exercising an ISO or by exercising an option other
than an ISO. Generally, there will be no tax consequences to a U.S. subsidiary
employer in connection with a disposition of shares acquired under an option
except that the U.S. subsidiary employer may be entitled to a deduction (and the
employee will recognize ordinary income) if shares acquired under an ISO are
disposed of before the applicable ISO holding periods have been satisfied.

      With respect to awards granted under the 1996 Stock Plan involving stock
or stock rights that is restricted as to transferability and subject to a
substantial risk of forfeiture, a participant will recognize ordinary income
equal to the fair market value of the shares received at the earlier of the time
at which the shares or stock rights become transferable or not subject to a
substantial risk of forfeiture unless, in the case of a restricted stock award,
but not in the case of restricted stock rights, the participant elects to be
taxed at the time of the award notwithstanding the restrictions (to minimize the
tax payable in respect of the appreciation in the value of the stock from the
time it is awarded until the restrictions lapse). The U.S. subsidiary employer,
if any, generally will be entitled to a deduction for the same amount unless
such deduction is limited by Section 162(m) of the Internal Revenue Code.


                                       10


      The foregoing provides only a very general description of the application
of U.S. federal income tax laws to awards under the 1996 Stock Plan. The summary
does not address the effects of foreign, state and local tax laws.

      Awards Granted. As of March 1, 2004, incentive and non-qualified stock
options and restricted stock and restricted stock rights for a total of
1,578,463 shares are outstanding under the 1996 Stock Plan. All of the
outstanding options expire at various times during the years 2006 to 2013. Since
inception of the 1996 Stock Plan through March 1, 2004, (a) options for a total
of 1,191,963 shares have been exercised, and (b) options and restricted stock
and restricted stock rights awards for the following number of shares have been
granted under the 1996 Stock Plan to the named executive officers of the Company
and specified groups: Michael F. Curran (who will become the Chairman of the
Board at the Annual Meeting, and will thereby be the Chairman, President, Chief
Executive Officer and Chief Operating Officer), 225,000 shares; John K. Allcorn
(Executive Vice President), 180,625 shares; James K. Tillery (Executive Vice
President of Willbros International, Inc.), 140,625 shares; Warren L. Williams
(Senior Vice President, Treasurer, and Chief Financial Officer), 130,625 shares;
John T. Dalton (Senior Vice President and General Counsel), 107,000 shares; all
current executive officers as a group, 783,875 shares; and all employees,
excluding current executive officers, as a group, 793,000 shares. All current
directors who are not employees of the Company are not eligible to receive
awards under the 1996 Stock Plan. Future awards under the 1996 Stock Plan are
not yet determinable. The closing price for the Common Stock on the New York
Stock Exchange on March 1, 2004, was $15.67 per share.

the ratification of KPMG as the Company's independent auditors for 2004.

      A representative of KPMG will be present at the Annual Meeting. Such
representative will be given the opportunity to make a statement if he or she
desires to do so and will be available to respond to appropriate questions.

AUDIT COMMITTEE PRE-APPROVAL POLICY

      It is the policy of the Audit Committee to pre-approve audit,
audit-related, tax and all other services specifically described by the Audit
Committee on a periodic basis up to a specified dollar amount. All other

EMPLOYMENT AGREEMENTS, TERMINATION OF EMPLOYMENT AND CHANGE IN CONTROL
ARRANGEMENTS

      None of the named executive officers of the Company have an employment
agreement with the Company.

      In October 1998, the Compensation Committee approved and recommended, and
the Board of Directors adopted, the Willbros Group, Inc. Severance Plan (the
"Severance Plan"), effective January 1, 1999. The Board of Directors adopted the
Severance Plan in lieu of entering into new employment agreements with the
executive officers at that time. Since the Severance Plan was scheduled to
expire on December 31, 2003, the Compensation Committee approved and
recommended, and the Board of Directors adopted, a restated and amended
Severance Plan (the "Restated Severance Plan"), effective September 25, 2003.
Each of the named executive officers of the Company is a participant in the
Restated Severance Plan. The Restated Severance Plan, which will remain in
effect until December 31, 2006, provides that a participant whose employment is
terminated other than for cause or who resigns due to (a) reduction of
compensation or other benefits, including incentive plans, (b) reduction in
scope of participant's authorities, duties, or title, or (c) material change in
the location of a participant's principal place of employment by the Company,
when a change in control of the Company is imminent or within three years after
a change in control of the Company has occurred, shall be entitled to severance
compensation (a) equal to 300% of the participant's annual base compensation,
(b) equal to 300% of the participant's greatest annual cash bonus received
during the 36-month period ending on the date of the change in control, (c)
equal to the aggregate annual incentive plan target opportunity that could have
been earned in the year termination of employment occurs, (d) that provides full
vesting of all of the participant's outstanding stock options, restricted stock
awards and other equity-based awards, and (e) that extends the participant's and
his dependents' coverage under the benefit plans for 24 months. The Restated
Severance Plan also provides that a participant who voluntarily terminates his
employment for reasons similar to termination of employment by the Company
within 18 months after a change in control of the Company has occurred shall be
entitled to a severance payment equal to the same severance compensation
applicable to the entitlement provided by termination of employment by the


                                       16


Company. Finally, the Restated Severance Plan provides that a participant whose
employment is terminated other than for cause prior to a change in control of
the Company shall be entitled to a severance payment equal to 100% of his base
salary then in effect. A participant who receives a severance payment under the
Restated Severance Plan will be subject to either a one year or two year
competition restriction depending on the basis for the termination. All taxes on
severance payments made under the Restated Severance Plan are the participant's
responsibility.

      All outstanding awards under the Company's 1996 Stock Plan, regardless of
any limitations or restrictions, become fully exercisable and free of all
restrictions, in the event of a change in control of the Company, as defined in
such Plan.

REPORT ON EXECUTIVE COMPENSATION

      The Compensation Committee of the Board of Directors (the "Compensation
Committee") administers the compensation program for executive officers of the
Company. The duties of the Compensation Committee include reviewing and
evaluating the Company's executive compensation program to assess its
effectiveness in attracting, motivating and retaining highly skilled executive
officers. The Compensation Committee also administers the Company's 1996 Stock
Plan and has access to outside compensation consulting firms and compensation
information.

      Compensation Philosophy

      The objectives of the Company's executive compensation program include:

      -     Providing a total executive compensation plan that is
            performance-driven and rewards business success based on an
            executive's individual performance;

      -     Aligning the financial interests of the executive officers with the
            performance of the Company;

      -     Emphasizing equity-based compensation for Company executives to
            reinforce management's focus on stockholder value; and

      -     Attracting, motivating, and retaining executive officers and key
            management personnel to achieve the Company's business objectives.

      The Compensation Committee adheres to an executive compensation philosophy
that supports the Company's business strategies. Compensation decisions under
the executive compensation program are made by the Compensation Committee and
approved by the Board of Directors.

      Compensation Program

      Company executives participate in a comprehensive compensation program
comprised of base salary, potential for annual discretionary incentive
compensation awards, and long-term equity-based opportunities in the form of
stock options and restricted stock awards.

      Base Salary. The level of base salary paid to executive officers is
determined on the basis of performance, experience and such other factors as may
be appropriately considered by the Compensation Committee. Each year the
Compensation Committee reviews the base salaries of the executives and considers
salary adjustments based on individual performance, overall financial results of
the Company, competitive position relative to the marketplace, and
cost-of-living indicators. As a result of that review, Mr. Tillery received a
salary increase in September 2003. Mr. Tillery received a raise because of his
promotion to Executive Vice President. None of the other executive officers of
the Company received a salary increase for 2003.

      Annual Incentive Program. In 2003, the Company's executive officers were
eligible for discretionary annual cash incentive awards based on performance
guidelines tied to annual operating performance levels. Each executive officer
is eligible to earn an individual award expressed as a percentage of base
salary.


                                       17


Executive officer incentive award opportunities vary by level of responsibility.
There is no minimum incentive award. The maximum percentage of base salary
payable as an incentive award ranges from 100% to 300%, depending on the
executive officer's position. The awards are based on the financial performance
of the Company and individual performance. Several factors are considered in
evaluating an executive's individual performance, which include achievement of
business strategy, successful accomplishment of business goals and objectives,
contribution toward the Company's profitability, and enhancement of stockholder
value. Due to the financial performance of the Company in 2003, none of the
executive officers were paid cash incentive bonus awards for 2003.

      Long-Term Incentive Program. In 1996, the Board of Directors and the
stockholders of the Company approved the 1996 Stock Plan (the "Stock Plan"). The
Stock Plan permits the Compensation Committee to grant various stock-based
awards, including options, stock appreciation rights, and restricted stock, to
executive officers and key management employees of the Company based on
competitive practices and the Company's overall performance. Stock options and
restricted stock awards are designed to provide grantees with the opportunity to
acquire a proprietary interest in the Company and to give such persons a
stronger incentive to work for the continued success of the Company. An option
award may be either an incentive stock option ("ISO") or a non-qualified stock
option ("NSO"). The Compensation Committee takes into account management's
recommendations regarding the number of shares or options and the number of
shares of restricted stock to be awarded to specific employees. There were no
awards granted under the Company's 1996 Stock Plan to the executive officers
during 2003.

      To date, the Compensation Committee has granted ISO, NSO and restricted
stock awards to executive officers from time to time. Both ISO and NSO awards
entitle the employee to purchase a specified number of shares of the Company's
Common Stock at a specified price during a specified period. Both the ISO awards
and the NSO awards have a 10-year term. Both types of awards are designed as an
incentive for future performance by the creation of stockholder value over the
long-term since the greatest benefit of the options is realized only if stock
price appreciation occurs. Restricted stock awards are grants of a specified
number of shares of the Company's Common Stock in which the employee's rights to
the shares are limited until the shares vest and cease to be subject to the
restrictions. The employee obtains full ownership of the unrestricted shares of
stock when it vests. Vesting may be tied to a specified time period or the
achievement of certain performance goals. The Company uses stock options and
restricted stock awards as its long-term incentive devices since stock options
and restricted stock awards provide the clearest tie between enhanced
stockholder wealth and executive pay.

      Chief Executive Officer Compensation for 2003

      Mr. Curran's overall compensation is determined in the same manner as is
the compensation for the other executive officers. As a result of the depressed
state of the energy industry, Mr. Curran did not receive a salary increase nor a
bonus for 2003. As a significant stockholder of the Company, Mr. Curran
continues to have strong incentive to create value for the Company's
stockholders. There were no awards granted under the Company's 1996 Stock Plan
to Mr. Curran during 2003.

      Policy Regarding Tax Deductibility of Executive Compensation

      Section 162(m) of the U.S. Internal Revenue Code places a $1 million per
person limitation on the United States tax deduction a U.S. subsidiary employer
of a publicly-held corporation may take for compensation paid to the Company's
Chief Executive Officer and its four other highest paid executive officers,
except compensation which constitutes performance-based compensation as defined
by the U.S. Internal Revenue Code is not subject to the $1 million limit. The
Compensation Committee generally intends to grant awards under the Company's
1996 Stock Plan consistent with the terms of Section 162(m) so that such awards
will not be subject to the $1 million limit. While the Company intends to pursue
a strategy of maximizing the deductibility of compensation paid to executive
officers in the future, it also intends to maintain the flexibility to take
actions that it considers to be in the Company's best interests and to take into
consideration factors other than deductibility. In doing so, the Compensation
Committee may utilize alternatives such as deferring compensation to qualify
compensation for deductibility and may rely on grandfathering provisions with
respect to existing compensation commitments. If any executive officer


                                       18


compensation exceeds this limitation, it is expected that such cases will
represent isolated, nonrecurring situations arising from special circumstances.

      The Compensation Committee and the Board of Directors believe that the
executive compensation policies promote the interest of the stockholders and the
Company effectively, and the various compensation opportunities afforded the
executive officers are appropriately balanced to provide motivation for
executives to contribute to the profitability and overall success of the
Company.

                             COMPENSATION COMMITTEE

                         James B. Taylor, Jr. (Chairman)
                               Rodney B. Mitchell

      The Report on Executive Compensation shall not be deemed incorporated by
reference by any general statement incorporating by reference this Proxy
Statement into any filing under the Securities Act of 1933, as amended, or the
Securities Exchange Act of 1934, as amended, except to the extent that the
Company specifically incorporates this information by reference, and shall not
otherwise be deemed filed under such Acts.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

      During 2003, the Compensation Committee was composed of James B. Taylor,
Jr., Rodney B. Mitchell, and Michael J. Pink, all of whom are non-employee
directors of the Company. During 2003, none of the Company's executive officers
served on the board of directors or on the compensation committee of any other
entity who had an executive officer that served either on the Company's Board of
Directors or on its Compensation Committee.

PERFORMANCE GRAPH

      The following graph compares the yearly percentage change in the
cumulative total stockholder return on the Company's Common Stock during the
period commencing January 1, 1999, and ending on December 31, 2003, with the
cumulative total return on the S&P 500 Index and the S&P 500 Construction &
Engineering Index. The comparison assumes $100 was invested December 31, 1998,
in the Company's Common Stock and in each of the foregoing indices and assumes
reinvestment of dividends.

                          REPORT OF THE AUDIT COMMITTEE

      Securities and Exchange Commission rules require that a company's proxy
statement contain a report of its audit committee. The Company's Audit Committee
consisted of four directors until the retirement of Mr. Waldvogel in March 2004.
The role of the Audit Committee is to assist the Board of Directors in its
oversight of the Company's financial reporting process.

      The Audit Committee has reviewed and discussed the audited financial
statements of the Company for the fiscal year 2003 with management and with the
Company's independent auditors. Specifically, the Audit Committee has discussed
with the independent auditors matters required to be discussed by Statement on
Auditing Standards No. 61, Communication with Audit Committees.

      The Audit Committee has received the written disclosures and the letter
from the Company's independent accountants, KPMG LLP, required by Independence
Standards Board No. 1, Independence Discussions With Audit Committees.
Additionally, the Audit Committee has discussed with KPMG the issue of its
independence from the Company and has concluded that KPMG is independent.

      Based on its review of the audited financial statements and the various
discussions noted above, the Audit Committee recommended to the Board of
Directors that the audited financial statements be included in the Company's
Annual Report on Form 10-K for the fiscal year ended December 31, 2003, to be
filed with the Securities and Exchange Commission.

                                 AUDIT COMMITTEE

                     Guy E. Waldvogel (until March 10, 2004)

      The Report of the Audit Committee shall not be deemed incorporated by
reference by any general statement incorporating by reference this Proxy
Statement into any filing under the Securities Act of 1933, as amended, or the
Securities Exchange Act of 1934, as amended, except to the extent that the
Company specifically incorporates this information by reference, and shall not
otherwise be deemed filed under such Acts.

                              CERTAIN TRANSACTIONS

      The Board of Directors previously approved an Employee Stock Purchase
Program (the "Program"). Under the Program, selected executives and officers of
the Company were given the opportunity to borrow funds on an interest free basis
for the purpose of exercising vested stock options granted to the executives
under the Company's 1996 Stock Plan. All such loans are full recourse and
therefore secured by Company


                                       20


stock. The maximum amount that could be loaned to individual executives under
the Program is $250,000. Each loan has a maximum term of five years and does not
bear interest unless not repaid on the due date. The loan will become due 90
days after termination of employment or on the normal due date of the loan,
whichever is first. Pursuant to the Program, in March 2002, certain executive
officers of the Company became indebted to the Company in amounts in excess of
$60,000 under various notes. The following table sets forth, as to the persons
shown, the largest amounts of their indebtedness outstanding, the interest
rates, the final maturity dates and the outstanding balances of such
indebtedness as of March 1, 2004:

      In accordance with the Sarbanes-Oxley Act of 2002, the Company in the
future will no longer make loans to executive officers of the Company.

             SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

      Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
the Company's directors and executive officers, and persons who own more than
10% of the Common Stock, to report their initial ownership of the Common Stock
and any subsequent changes in that ownership to the Securities and Exchange
Commission and the New York Stock Exchange, and to furnish the Company with a
copy of each such report. The Securities and Exchange Commission regulations
impose specific due dates for such reports, and the Company is required to
disclose in this Proxy Statement any failure to file by these dates during and
with respect to fiscal 2003.

      To the Company's knowledge, based solely on review of the copies of such
reports furnished to the Company and written representations that no other
reports were required, during and with respect to fiscal 2003, all Section 16(a)
filing requirements applicable to its officers, directors and more than 10%
stockholders were complied with.

                                  OTHER MATTERS

MATTERS WHICH MAY COME BEFORE THE ANNUAL MEETING

      The Board of Directors knows of no matters other than those described in
this Proxy Statement which will be brought before the Annual Meeting for a vote
of the stockholders. If any other matter properly comes before the Annual
Meeting for a stockholder vote, the persons named in the accompanying proxy will
vote thereon in accordance with their best judgment.

PROPOSALS OF STOCKHOLDERS

      Proposals of stockholders intended to be presented at the Company's 2005
Annual Meeting of Stockholders must be received at the principal executive
offices of the Company, Plaza 2000 Building, 50th Street, 8th Floor, P.O. Box
0816-01098, Panama, Republic of Panama, on or before December 24, 2004, to be
considered for inclusion in the Company's proxy statement and accompanying proxy
for that meeting.

      If a stockholder, who intends to present a proposal at the Company's 2005
Annual Meeting of Stockholders and has not sought inclusion of the proposal in
the Company's proxy materials pursuant to Rule 14a-8, fails to provide the
Company with notice of such proposal by March 9, 2005, then the persons named in
the proxies solicited by the Company's Board of Directors for its 2005 Annual
Meeting of Stockholders may exercise discretionary voting power with respect to
such proposal.

                             AUDIT COMMITTEE CHARTER
                            REVISED DECEMBER 15, 2003


1.    COMMITTEE PURPOSE

      The Audit Committee is appointed by the Board of Directors (the "Board")
to assist the Board in monitoring (i) the integrity of the financial statements
of the Company; (ii) the independent auditor's qualifications and independence;
(iii) the performance of the Company's internal audit function; and (iv) the
Company's compliance with legal and regulatory requirements. The Audit Committee
shall prepare the report required by the rules of the Securities and Exchange
Commission (the "Commission") to be included in the Company's annual proxy
statement.

      Although the Committee has the powers and responsibilities set forth in
this Charter, the role of the Committee is oversight. It is not the duty of the
Committee to plan or conduct audits or to determine that the Company's financial
statements and disclosures are complete and accurate and are in accordance with
generally accepted accounting principles and applicable rules and regulations.
These are the responsibilities of management and the independent auditor.

2.    COMMITTEE MEMBERSHIP

      The Audit Committee shall consist of no fewer than three members, each of
whom shall meet the independence and experience requirements of the New York
Stock Exchange, Section 10A(m)(3) of the Securities and Exchange Act of 1934
(the "Exchange Act"), and the rules and regulations of the Commission. Audit
Committee members shall not simultaneously serve on the audit committees of more
than two other public companies. At least one member of the Audit Committee
shall be an "audit committee financial expert" as defined by the Commission.

      The members of the Audit Committee shall be appointed by the Board on the
recommendation of the Nominating/Corporate Governance Committee. Audit Committee
members may be replaced by the Board.

3.    COMMITTEE AUTHORITY AND RESPONSIBILITIES

      The Audit Committee shall have the sole authority to appoint or replace
the independent auditor. The Audit Committee shall be directly responsible for
the compensation and oversight of the work of the independent auditor (including
resolution of disagreements between management and the independent auditor
regarding financial reporting) for the purpose of preparing or issuing an audit
report or related work. The independent auditor shall report directly to the
Audit Committee.

      The Audit Committee shall pre-approve all auditing services and permitted
non-audit services (including the fees and terms thereof) to be performed by the
Company by its independent auditor, subject to the de minimus exceptions
described in Section 10A(i)(1)(B) of the Exchange Act and the rules and
regulations of the Commission which are approved by the Committee prior to the
completion of the audit.

      The Audit Committee shall make regular reports to the Board. The Audit
Committee shall review and assess the adequacy of this Charter annually and
recommend any proposed changes to the Board for approval. The Audit Committee
shall annually review the Audit Committee's own performance.


                                      A-1


      To the extent it deems necessary and appropriate, the Audit Committee
shall:

      a.    At least annually, obtain and review a report by the independent
            auditor describing (i) the independent auditor's internal
            quality-control procedures; (ii) any material issues raised by the
            most recent internal quality-control review, or peer review, of the
            firm, or by any inquiry or investigation by governmental or
            professional authorities within the preceding five years respecting
            one or more independent audits carried out by the firm; (iii) any
            steps taken to deal with any such issues; and (iv) all relationships
            between the independent auditor and the Company. Evaluate the
            independent auditor's qualifications, performance, and independence,
            including considering whether the auditor's quality controls are
            adequate and the provision of permitted non-audit services is
            compatible with maintaining the auditor's independence, taking into
            account the opinions of management and the internal auditors. The
            Audit Committee shall present its conclusions with respect to the
            independent auditor to the full Board.

      b.    Review and discuss the annual audited financial statements with
            management and the independent auditor, including the Company's
            disclosures under "Management's Discussion and Analysis of Financial
            Condition and Results of Operations." Recommend to the Board whether
            the annual financial statements should be included in the Company's
            Form 10-K.

      c.    Review and discuss the Company's quarterly financial statements with

            of the quarterly financial statements.

      d.    Discuss with management and the independent auditor significant
            financial reporting issues and judgments made in connection with the
            preparation of the Company's financial statements, including any
            significant changes in the Company's selection or application of
            accounting principles, any major issues as to the adequacy of the
            Company's internal controls, and any special steps adopted in light
            of material control deficiencies.

      e.    Review and discuss quarterly reports from the independent auditors
            on (i) all critical accounting policies and practices to be used;
            (ii) all alternative treatments of financial information within
            generally accepted accounting principles that have been discussed
            with management, ramifications of the use of such alternative
            disclosures and treatments, and the treatment preferred by the
            independent auditor; and (iii) other material written communications
            between the independent auditor and management, such as any
            managerial letter or schedule of unadjusted differences.

      f.    Discuss with management the Company's earnings press releases,
            including the use of "pro forma" or "adjusted" non-GAAP information,
            as well as financial information and earnings guidance provided to
            analysts and rating agencies. Such discussion may be done generally
            (consisting of the types of information to be disclosed and the
            types of presentations to be made). The Audit Committee need not
            discuss in advance each earnings release or each instance in which
            the Company may provide earnings guidance.

      g.    Discuss with management and the independent auditor the effect of
            regulatory and accounting initiatives as well as off-balance sheet
            structures on the Company's financial statements.


                                      A-2


      h.    Discuss with management the Company's major financial risk exposures
            and the steps management has taken to monitor and control such
            exposures, including the Company's risk assessment and risk
            management policies.

      i.    Discuss with the independent auditor the matters required to be
            discussed by Statement on Auditing Standards No. 61 relating to the
            conduct of the audit, including any difficulties encountered in the
            course of the audit work, restrictions on the scope of activities or
            access to requested information, and any significant disagreements
            with management.

      j.    Review disclosures made to the Audit Committee by the Company's CEO
            and CFO during their certification process for the Form 10-K and
            Forms 10-Q about any significant deficiencies in the design or
            operation of internal controls or material weaknesses therein and
            any fraud involving management or other employees who have a
            significant role in the Company's internal controls.

      k.    Review and evaluate the lead partner of the independent auditor
            team.

            having primary responsibility for the audit and audit partner
            responsible for reviewing the audit, as required by law. Consider
            whether, in order to assure continuing auditor independence, it is
            appropriate to adopt a policy of rotating the independent auditing
            firm on a regular basis.

      m.    Recommend to the Board policies for the hiring of employees or
            former employees of the independent auditor who participated in any
            capacity in the audit of the Company.

      n.    Discuss with the national office of the independent auditor issues
            on which they were consulted by the Company's audit team and matters
            of audit quality and consistency.

      o.    Meet with the independent auditor prior to the audit to discuss the
            planning and staffing of the audit.

      p.    Review the appointment and replacement of the senior internal
            auditing executive.

      q.    Review the significant reports to management prepared by the
            internal audit department and management's responses.

      r.    Discuss with the independent auditor and management the internal
            audit department responsibilities, budget and staffing, and any
            recommended changes in the planned scope of the internal audit.

      s.    Obtain from the independent auditor assurance that Section 10A(b) of
            the Exchange Act has not been impacted.

      t.    Obtain reports from management, the Company's senior internal
            auditing executive, and the independent auditor that the Company and
            its subsidiary/foreign affiliated entities are in conformity with
            applicable legal requirements and the Company's Code of Business
            Conduct and Ethics. Review reports and disclosures of insider and
            affiliated party transactions. Advise the Board with respect to the
            Company's policies and procedures regarding


                                      A-3


            compliance with applicable laws and regulations, and with the
            Company's Code of Business Conduct and Ethics.

      u.    Establish procedures for the receipt, retention, and treatment of
            complaints received by the Company regarding accounting, internal
            accounting controls or auditing matters, and the confidential,
            anonymous submission by employees of the Company of concerns
            regarding questionable accounting or auditing matters.

      v.    Discuss with management and the independent auditor any
            correspondence with regulators or governmental agencies and any
            published reports which raise material issues regarding the
            Company's financial statements or accounting policies.

      w.    Discuss with the Company's General Counsel legal matters that may
            have a material effect on the financial statements or the Company's
            compliance policies.

4.    COMMITTEE MEETINGS

      The Audit Committee shall meet as often as it determines, but not less
frequently than quarterly. The Audit Committee shall meet periodically with
management, the internal auditors, and the independent auditor in separate
executive sessions. The Audit Committee may request any officer or employee of
the Company or the Company's outside counsel or independent auditor to attend a
meeting of the Committee or to meet with any members of, or consultants to, the
Committee.

      The Audit Committee may form and delegate authority to subcommittees
consisting of one or more members when appropriate, including the authority to
grant pre-approvals of audit and permitted non-audit services, provided that the
decisions of such subcommittee to grant pre-approvals shall be presented to the
full Audit Committee at its next meeting.

5.    AUDIT COMMITTEE RESOURCES

      The Audit Committee shall have the authority, to the extent it deems
necessary or appropriate, to retain independent legal, accounting, or other
advisors. The Company shall provide for appropriate funding, as determined by
the Audit Committee, for payment of compensation to the independent auditor for
the purpose of rendering or issuing an audit report and to any advisors employed
by the Audit Committee.
