This Proxy Statement and accompanying proxy were first sent on or about March 31, 1998, to stockholders of record on March 27, 1998. 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 adoption of procedural improvements to Panama corporate law and approval of a Certificate of Amendment to the Company's Restated Articles of Incorporation to effect certain of these improvements, 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 March 27, 1998 (the "Record Date"), will be entitled to vote at the Annual Meeting. As of the Record Date, there were issued and outstanding 15,002,946 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 ratification of the appointment of the independent auditors. With regard to the adoption of the procedural improvements to Panama corporate law and the approval of the Certificate of Amendment to the Company's Restated Articles of Incorporation, a broker non- vote will have the effect of a negative vote. 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 1999 and 2000, respectively. In accordance with the recommendation of the Nominating Committee, the Board of Directors has nominated Michael J. Pink, John H. Williams and ----------------------------------------- for election as Class II directors. Messrs. Pink and Williams, who currently serve as Class II directors and whose terms expire at the Annual Meeting, are standing for re-election as Class II directors for terms expiring at the annual meeting of stockholders in 2001. Bryan H. Lawrence, who currently serves as a Class II director and whose term also expires at the Annual Meeting, has elected not to seek re-election as a director. Mr. -------------- - -------, who currently does not serve as a director, has been nominated to fill the position being vacated by Mr. Lawrence. Mr. ----------------- is standing for election as a Class II director for a term expiring at the annual meeting of stockholders in 2001. Accordingly, the accompanying proxy solicits your vote for three 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. Pink, Williams and ------------ - ---------------. 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 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. 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. Nominees for Directors Class II (Term Expires May 2001) Michael J.

Compensation of Directors Employee directors receive no additional compensation for service on the Board of Directors or any committee thereof. Non- employee directors receive an annual retainer of $18,000 plus a fee of $1,000 per meeting for attending meetings of the Board of Directors and any committee thereof. Non-employee directors also automatically receive non-qualified stock options under the Willbros Group, Inc. Director Stock Plan (the "Director Plan"). Under the Director Plan, an initial option to purchase up to 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 1,000 shares of Common Stock 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 Plan is equal to the fair market value of the Common Stock on the date of grant. A total of 125,000 shares of Common Stock is available for issuance under the Director Plan. During fiscal 1997, Messrs. Lawrence, Leidel and Waldvogel were each granted an option to purchase 1,000 shares of Common Stock at an exercise price of $18.63 per share and Messrs. Pink and Williams were each granted an option to purchase 1,000 shares of Common Stock at an exercise price of $19.44 per share. No options have been exercised under the Director 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. Meetings and Committees of the Board of Directors During 1997, the Board of Directors held four meetings. Each director was present at 75 percent 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 1997. The Board of Directors has a standing Executive Committee, Audit Committee, Nominating Committee, Compensation Committee and Stock Plan Committee. The Executive Committee is composed of Messrs. Bump (Chairman), Spreitzer, Lawrence and 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 held two meetings during 1997. The Audit Committee is composed of Messrs. Leidel (Chairman) and Waldvogel, each of whom is a non-employee director of the Company. 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 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 reviews at least once each year, the terms of all material transactions and arrangements, if any, between the Company and its directors, officers and affiliates. The Audit Committee held three meetings during 1997. 4 The Nominating Committee is composed of Messrs. Williams (Chairman) and Pink, each of whom is a non-employee director of the Company. The Nominating 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. Additionally, the Nominating Committee makes recommendations to the Board of Directors regarding changes in the size of the Board of Directors. Qualifications considered by the Nominating Committee for director candidates 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 Nominating Committee will consider director candidates submitted to it by other directors, employees and stockholders. 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 first week of May. The Nominating Committee met once during 1997. The Compensation Committee is composed of Messrs. Waldvogel (Chairman), Spreitzer and Williams. 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. 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 two meetings during 1997. The Stock Plan Committee is composed of Messrs. Waldvogel (Chairman) and Williams, each of whom is a non-employee director of the Company. The Stock Plan Committee administers the Willbros Group, Inc. 1996 Stock Plan (the "Company's 1996 Stock Plan"). The Stock Plan Committee held two meetings during 1997. PROPOSAL TWO ADOPTION OF PROCEDURAL IMPROVEMENTS TO PANAMA CORPORATE LAW AND APPROVAL OF A CERTIFICATE OF AMENDMENT TO THE ARTICLES OF INCORPORATION OF THE COMPANY TO EFFECT CERTAIN OF THESE IMPROVEMENTS General The Republic of Panama has adopted Decree Law No. 5 of July 2, 1997 (the "Decree"), which provides for certain procedural improvements to the corporate laws of the Republic of Panama. The Decree provides a number of significant benefits for Panama corporations, including among others (a) the redomiciliation of a Panama corporation may be made to another jurisdiction accepting redomiciliation, (b) the meetings of a corporation's board of directors may be held by telephone conference or any other means of electronic communication, (c) a corporation's board of directors may adopt resolutions by written consent, and (d) the maintenance of a corporation's corporate books may be made by any electronic, optical or magnetic means. The Company, as a Panama corporation, will benefit from the passage of the Decree if the 5 stockholders of the Company adopt a resolution electing that the Company be governed by the provisions of the Decree and such resolution is recorded in the Public Registry Office of the Republic of Panama. The Board of Directors has approved and recommends that the stockholders of the Company approve a proposal (the "Proposal") that adopts the Decree and approves an amendment to the Company's Charter to effect certain provisions of the Decree as discussed below. The Board of Directors believes that the adoption of the Proposal will provide several advantages to the Company and its stockholders as discussed below. A number of the provisions of the Decree apply only to corporations that engage in business as merchants in Panama. Since the Company does not engage in business as a merchant in Panama, the following summary includes only the material features of the Decree that are relevant to the Company's operations. Such summary, however, is not a substitute for a review of the entire Decree, an English translation of which is set forth as Exhibit A hereto. Such summary is qualified in its entirety by reference to the Decree. Reasons for Adopting, and Summary of, the Decree Change of Domicile. The Decree permits a Panama corporation to more easily change its domicile to any jurisdiction accepting redomiciliation. Under the Company's current Charter, if the Company decided in the future to change its domicile for tax, political or other reasons, it would likely be necessary to sell or transfer its assets and/or to dissolve the Company and/or to merge with a foreign corporation. Such transactions are inconvenient, costly and would likely require specific approval from the stockholders of the Company. In connection with the adoption of the Decree, the Board of Directors proposes that a Certificate of Amendment to the Company's Charter, which is set forth as Exhibit B hereto (the "Certificate of Amendment"), be approved by the stockholders of the Company. The Certificate of Amendment would amend the Charter to enable the Company, without further stockholder approval, to change its domicile and continue its existence under the laws of another country at any time that the Board of Directors considered it to be in the best interests of the Company. The approval of the Proposal would give the Company greater flexibility to respond to future developments without the costs and delays associated with the need to sell or transfer assets, dissolve the Company or merge with another corporation. The ability to change domicile, as the Board of Directors determines to be in the Company's best interests, would also permit the Company to avoid the delays, uncertainties and extra expenses which would be incurred in holding a special meeting of stockholders solely to obtain approval for a change in domicile. As of the date on which this Proxy Statement is being mailed, there are no plans under consideration for the redomiciliation of the Company. Sale of Assets. Under the Decree, the disposal or encumbrance of corporate assets may be made by the subscribers, partners, stockholders, administrators, directors, attorneys in fact or liquidators of a Panama corporation, as provided in the corporation's articles of incorporation, or if not so provided, as in accordance with the corporate laws of Panama. The Certificate of Amendment would also amend the Charter to clarify that under the Decree, only a sale of all or substantially all of the assets of the Company would require approval from the Company's stockholders. As of the date on which this Proxy Statement is being mailed, there are no plans under consideration for any material sale of assets of the Company. If in the future there are any potential sales of assets which require stockholder approval, such approval will be sought at the appropriate time. Meetings by Telephone Conference; Action by Written Consent. The Decree enacts more modern provisions regarding the functioning of the boards of directors of Panama corporations. Until the passage of the Decree, it was not clear whether Panama corporations, such as the Company, could conduct board of directors meetings by telephone or adopt resolutions by written consent of the directors. The Decree allows meetings of the board of directors to be held via telephone conference, facsimile transmission or any other electronic means of communication in which the participants are in direct communication. The Decree also allows resolutions of the board of directors to be adopted by the written consents of the directors in lieu of holding a meeting. With respect to the Company, matters sometimes arise between scheduled Board 6 meetings that require action by the Board of Directors. The Board of Directors believes that the adoption of the Decree to permit telephonic Board meetings and actions by written consent of the Directors would greatly facilitate and expedite Board actions regarding important matters arising between scheduled Board meetings. Corporate Records. Under the Decree, a Panama corporation is no longer required to have its minute book or its stock register book countersigned by a Panama Circuit Court or to complete such records in long hand. Upon adoption of the Decree by the Company's stockholders, the Company would be allowed to maintain its corporate records by any manual, electronic or other means, provided that such means must ensure accuracy and must be convertible into printed material. Powers of Attorney. The Decree provides that general or limited powers of attorney shall be deemed effective against third parties when they have been granted in the form of a notarial instrument or when the signature of the grantor has been recognized before a Notary Public, without having to record the instrument in the Public Registry Office in the Republic of Panama. General Pledge of Assets. Under the Decree, a Panama corporation may grant a general pledge over its assets located outside of Panama. Such pledge would have priority over all other credits except those affecting specific assets. In order to enjoy priority over all other unsecured credits, the general pledge of assets must be recorded in the Public Registry Office of the Republic of Panama. Corporate Entities. The Decree allows two or more natural persons or corporate entities to form a company of any kind to serve as a stockholder, director, officer, administrator, attorney in fact or liquidator of a Panama corporation. Recordation of Financial Statements. At the option of the corporation, Panama corporations may file their financial statements as a matter of public record with the Public Registry Office of the Republic of Panama if such financial statements have been approved by the corporation's board of directors or stockholders and have been countersigned by a certified public accountant. The Company believes that the above described features of the Decree provide significant benefits to the Company and constitute the main reasons for the adoption of the Decree. The Decree also contains a number of other provisions that either do not apply or are of lesser importance to the Company. For a more complete description of the provisions of the Decree, reference is made to the full text of the Decree, an English translation of which is attached as Exhibit A hereto. Vote Required and Effective Date The Proposal must be approved by the affirmative vote of the holders of a majority of the outstanding shares of Common Stock. If approved by the stockholders, the Proposal will become effective upon filing the Certificate of Amendment and the resolutions adopting the Decree with the Public Registry Office of the Republic of Panama, which will occur as soon as reasonably practicable. The Board of Directors recommends a vote "FOR" approval of the Proposal. PROPOSAL THREE RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS Upon the recommendation of the Audit Committee, the Board of Directors has appointed KPMG Peat Marwick as the independent auditors of the Company for the fiscal year ending December 31, 1998. KPMG Peat Marwick have been the independent auditors of Willbros since 1987. A proposal will be presented at the Annual Meeting asking the stockholders to ratify the appointment of KPMG Peat Marwick as the Company's 7 independent auditors. If the stockholders do not ratify the appointment of KPMG Peat Marwick, the Board of Directors will reconsider the appointment. 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 adoption of this proposal. The Board of Directors recommends a vote "FOR" the ratification of KPMG Peat Marwick as the Company's independent auditors for 1998. A representative of KPMG Peat Marwick will be present at the Annual Meeting. Such representative will be given the opportunity to make a statement if he desires to do so and will be available to respond to appropriate questions.

Pension Plan Table The following table sets forth estimated annual lifetime retirement benefits payable to eligible employees (including the persons named in the Summary Compensation Table) under the Company's qualified retirement and non-qualified benefit restoration plans in the specified compensation and years of service classifications following retirement at age 65. Estimated Annual Lifetime Retirement Benefits for Average Years of Service Indicated Annual ---------------------------------------------------- Earnings 15 Years 20 Years 25 Years 30 Years 35 Years - -------- -------- -------- -------- -------- -------- $125,000 $ 33,574 $ 44,703 $ 55,926 $ 67,055 $ 78,278 150,000 40,899 54,453 68,126 81,680 95,353 175,000 48,224 64,203 80,326 96,305 112,428 200,000 55,549 73,953 92,526 110,930 129,503 300,000 84,849 112,953 141,326 169,430 197,803 400,000 114,149 151,953 190,126 227,930 266,103 600,000 172,749 229,953 287,726 344,930 402,703 The years of credited service for the persons named in the Summary Compensation Table as of December 31, 1997, are: Larry J. Bump, 20 years; Gary L. Bracken, 22 years; M. Kieth Phillips, 19 years; Melvin F. Spreitzer, 23 years; and James R. Beasley, 16 years. Amounts shown in the Pension Plan Table 11 are straight life annuities for years of service classifications listed. The Pension Plan is an "excess" plan and is not offset by receipt of Social Security benefits or any other amounts. The Company maintains a contributory retirement plan for all eligible employees (excluding nonresident aliens, union members, and certain temporary and contract employees). Participants who retire at age 65 are entitled to receive retirement benefits determined on the basis of a formula reflecting years of credited service multiplied by a percentage of the final average salary. The final average salary is derived from base salary and annual bonus received in the highest-paid five consecutive years during the participant's total years of service with the Company. Benefits are nonforfeitable when a participant completes five years of vesting service. Benefits may commence when a participant reaches the later of Normal Retirement Date (age 65) or the five-year anniversary of the participation date. Reduced benefits may commence upon a participant's attaining age 55 and five years of participation. Multiple joint and survivor benefit options are available to married participants. Contributions are made by the Company based on the actuarially determined cost of accrued retirement benefits, subject to statutory limits. Employee contributions are 2 percent of compensation up to the limit imposed under Section 401(a)(17) of the Internal Revenue Code of 1986, as amended (the "Code"). Employee contributions and interest may be distributed upon the participant's request at termination or retirement, resulting in a reduced annuity for vested participants. In addition to the qualified retirement plan, the Company maintains an Executive Benefit Restoration Plan ("EBRP") to partially restore retirement benefits to its top four officers. Benefit reductions resulting from statutory limits will be partially replaced in the form of a lump sum benefit, according to the plan, which limits the amount of compensation to be used in calculating the restoration benefit to 150 percent of the participant's base salary. The Company makes an annual, actuarially calculated contribution to an irrevocable trust for future distributions from the EBRP. Employment Agreements, Termination of Employment and Change in Control Arrangements The Company has employment agreements with all of the executive officers of the Company. Effective January 1, 1996, the Company entered into Employment Agreements with Messrs. Bump, Bracken, Spreitzer and Phillips, which remain in effect until December 31, 1998, except for Mr. Bracken's which was terminated effective February 20, 1998, as discussed below. Effective January 1, 1997, the Company entered into an Employment Agreement with Mr. Beasley which will also remain in effect until December 31, 1998. Each year, each executive officer receives an annual base salary equal to his total annual base salary in effect at the beginning of that year, which may be increased, but not decreased. Each agreement provides for salary adjustments for cost of living increases; the payment of bonuses at the discretion of the Board of Directors; and (except for Mr. Beasley) the eligibility to participate during calendar years 1996 through 1998 in the Willbros USA, Inc. Management Incentive Plan, dated January 1, 1996 (the "Incentive Plan"). Mr. Beasley is eligible to participate during calendar years 1997 and 1998 in the Willbros Engineers, Inc. Management Incentive Plan dated January 1, 1996. Each agreement contains a confidentiality provision which will be in effect for two years after termination of the employee's employment, as well as a non- competition provision with which the employee's employer has the right to require compliance for two years from the date of termination of employment or retirement. Each agreement also contains change of control provisions whereby, if the employee's employment is terminated for any reason within 12 months after the occurrence of a change of control of the Company or if following a change of control of the Company the employee's employment is not continued upon expiration of the current employment agreement term, such employee will be entitled to elect to receive a severance payment equal to the sum of (a) three times his base 12 salary then in effect, (b) three times the average incentive payment earned for the three years preceding the termination of employment, (c) an early retirement discount reduction, and (d) a tax recovery payment. Effective November 5, 1997, Gary L. Bracken's active service with the Company ceased upon his resignation from the offices of President, Chief Operating Officer and Director of the Company. Mr. Bracken's employment continued until February 20, 1998, at which time Willbros USA, Inc. ("Willbros USA") entered into a Separation Agreement with Mr. Bracken under which Mr. Bracken retired from employment with Willbros USA and all affiliated companies. Pursuant to such Separation Agreement, Willbros USA made a lump sum payment to Mr. Bracken in the amount of $719,090 (including a 1997 management incentive compensation plan payment of $40,950) and agreed to pay Mr. Bracken an amount equal to the incentive bonus, if any, that would have been payable to him under the Incentive Plan had Mr. Bracken continued as an Incentive Plan participant through the end of calendar year 1998. In connection with Mr. Bracken's retirement, the exercise date of certain stock options previously awarded to Mr. Bracken was accelerated. 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") is responsible for establishing and administering the Company's executive officer salary and annual incentive compensation programs. The Stock Plan Committee of the Board of Directors (the "Stock Plan Committee") is responsible for administering the Company's 1996 Stock Plan. The majority of the Compensation Committee members and all of the Stock Plan Committee members are non-employee directors who are not eligible to participate in any of the Company's executive employee compensation programs. The Committees have access to independent compensation consultants and data. Executive Compensation Philosophy The Company's executive officer compensation program is designed to meet the following objectives: To connect the interests of the executive officers with Company performance and the interests of stockholders; To attract, retain and motivate executive employee talent; To assure that a portion of each executive officer's total compensation is dependent upon the appreciation of the Company's Common Stock; and To provide a balanced total compensation package that recognizes the individual contributions of each executive officer and the overall business performance of the Company. These objectives are met through a program comprised of base salary, incentive compensation plans tied to annual operating performance levels, and long-term incentive opportunities primarily in the form of stock-based awards. Compensation decisions under the executive employee compensation program with respect to the Company's executive officers are made by the Compensation Committee and ratified by the full Board of Directors. Each of the Company's executive officers has an employment contract which establishes incentive compensation terms and minimum base salary. 13 Executive Compensation Program The Compensation Committee conducts a full review of the Company's executive compensation program each year. This annual review includes analyzing survey data comparing the competitiveness of the Company's executive compensation to that of companies in similar lines of business or of comparable size and scope of operations. The Committee also considers compensation data compiled from surveys of a broader group of general industry companies supplied by nationally known compensation consulting firms. Base Salary. Each year the Compensation Committee considers base salary adjustments for each of the Company's executive officers, including a cost-of-living adjustment when appropriate. The employment agreements with the Company's executive officers specify that annual base salary percentage increases must be at least equal to the percentage increase in the published Consumer Price Index during the preceding calendar year. Annual Incentive Program. The Company's executive officers are eligible for annual cash incentive awards under Incentive Plans administered by the Compensation Committee. Each executive officer is eligible to earn an individual award expressed as a percentage of base salary. 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 percent to 300 percent, depending on the executive officer's position. The awards are granted when a specified financial performance level is achieved. In each case, the performance level is defined as a minimum rate of return which average total net assets employed in the business (excluding cash, cash equivalents and debt) must earn. This plan design takes into account the stockholders' interests by requiring the Company to achieve certain profitability levels before an executive officer is eligible to receive an annual incentive award. In addition, the Company's executive officers are eligible to receive discretionary bonus compensation as determined, on a subjective basis, by the Compensation Committee and/or the Board of Directors taking into account individual performance and merit. Long-Term Incentive Program. The Company's 1996 Stock Plan ("Stock Plan"), approved by the stockholders in 1996, permits the Stock Plan Committee, at its discretion, to grant various stock-based awards, including options, stock appreciation rights and restricted stock to the Company's executive officers, as well as to other key management employees. An option award may be either an incentive stock option ("ISO") or a non-qualified stock option ("NSO"). The Stock Plan Committee takes into account management's recommendations regarding the number of shares or options to be awarded to specific employees. To date, the Stock Plan Committee has granted only ISO and NSO awards. There were no awards granted during 1997. 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. All ISO awards have an exercise price equal to the closing market price of the Common Stock on the day of the grant and they vest 25 percent in each successive calendar year, beginning with the year of grant. The most recent NSO awards have an exercise price equal to the closing market price of the Common Stock on the day of the grant and vest 25 percent in each successive calendar year, beginning with the year of grant, subject to acceleration based on stock price increases. 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. Chief Executive Officer Compensation for 1997 In October 1996, the Compensation Committee approved, and the Board of Directors ratified, a cost-of-living salary increase of 4.5 percent for Mr. Bump in accordance with the terms of his employment 14 agreement. As a result of the Company's achieving certain financial performance levels for 1997, Mr. Bump earned a bonus of approximately $64,000 for 1997 under the terms of the annual Incentive Plan described above. Although Mr. Bump recommended to the Board of Directors that certain executive officers of the Company receive discretionary bonus compensation for their performance during 1997, Mr. Bump asked that he not be considered for a discretionary bonus in respect of 1997. As the Company's largest single stockholder, Mr. Bump 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. Bump or to any other key employee of the Company during 1997. Policy Regarding Tax Deductibility of Executive Compensation Section 162(m) of the Code places a $1 million per person limitation on the United States tax deduction the Company may take for compensation paid to its Chief Executive Officer and its four other highest paid executive officers, except compensation which constitutes performance-based compensation as defined by the Code is not subject to the $1 million limit. The Compensation and Stock Plan Committees believe that no compensation otherwise deductible for 1997 was subject to this deductibility limit. The Stock Plan 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. In other respects, the Compensation and Stock Plan Committees expect to take such actions in the future as may be necessary to preserve the deductibility of executive compensation to the extent reasonably practicable and consistent with other objectives of the Company's compensation program. In doing so, the Compensation and Stock Plan Committees 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 compensation exceeds this limitation, it is expected that such cases will represent isolated, nonrecurring situations arising from special circumstances. COMPENSATION COMMITTEE STOCK PLAN COMMITTEE Melvin F. Spreitzer Guy E. Waldvogel Guy E. Waldvogel John H. Williams John H. Williams 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 1997, Melvin F. Spreitzer, an executive officer of the Company, was a member of the Compensation Committee and participated in deliberations concerning executive officer compensation. The other two members of the Compensation Committee, Guy E. Waldvogel and John H. William, are non-employee directors of the Company. Since January 1, 1997, Mr. Spreitzer, an executive officer of the Company, has been indebted to the Company in amounts in excess of $60,000. The largest amount of such indebtedness outstanding during such period was $143,730. This indebtedness bears no interest and the outstanding balance of such indebtedness as of March 1, 1998, was $119,880. This indebtedness was incurred in connection with the exercise of options to purchase Common Stock and Preferred Stock of the Company pursuant to certain management and employee stock ownership plans. No shares will be sold in the future under these plans. 15 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 August 15, 1996 (the date on which the Company's Common Stock began trading publicly), and ending on December 31, 1997, with the cumulative total return on the S&P 500 Index and the S&P Engineering & Construction Index. The comparison assumes $100 was invested on August 15, 1996, in the Company's Common Stock and in each of the foregoing indices and assumes reinvestment of dividends.

CERTAIN TRANSACTIONS Since January 1, 1997, certain executive officers and a former executive officer of the Company have been indebted to the Company in amounts in excess of $60,000 under various notes. Such notes were issued to evidence certain loans by the Company to such officers in connection with the purchase of shares of Common Stock and Preferred Stock pursuant to certain management and employee stock ownership plans. No shares will be sold in the future under these plans.
