Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

     (d) On November 27, 2007, the Board of Directors (the “Board”) of Willbros Group, Inc. (the “Registrant”), upon the recommendation of the Nominating/Corporate Governance Committee of the Board, appointed Arlo B. DeKraai to serve as a Class III director of the Board, to fill a vacancy that existed in Class III, for a term expiring at the Annual Meeting of Stockholders of the Registrant in 2008 and until his successor is duly elected or chosen and qualifies, unless he sooner dies, resigns or is removed. He has not been appointed to any committees of the Board.

     The initial appointment of Mr. DeKraai to the Board was made pursuant to a contractual obligation of the Registrant set forth in that certain Share Purchase Agreement dated as of October 31, 2007, by and among the Registrant, Willbros USA, Inc., a subsidiary of the Registrant (“WUSA”), Integrated Service Company LLC (“InServ”), the 18 members of InServ and Arlo DeKraai, the founder, President, Chief Executive Officer (“CEO”) and principal owner of InServ, as Shareholders’ Representative (the “Share Purchase Agreement”), whereby WUSA purchased all of the outstanding limited liability company membership interests of InServ. As previously reported, the transactions contemplated by the Share Purchase Agreement were consummated on November 20, 2007. Mr. DeKraai continues to serve as President and CEO of InServ, an indirect wholly owned subsidiary of the Registrant. He will not receive any additional compensation for his service on the Board. The Registrant reimburses all directors for out-of-pocket expenses incurred by them in connection with their services as directors.

     On November 20, 2007, InServ entered into an Employment Agreement (the “Agreement”) with Mr. DeKraai. The term of the Agreement is three years, commencing on November 20, 2007, and ending on November 20, 2010 (the “Employment Period”). During the Employment Period, Mr. DeKraai will earn a base salary of $330,200 per year. Mr. DeKraai will be eligible for increases in such base salary during the Employment Period. Additionally, Mr. DeKraai will be eligible for participation in the Willbros Management Incentive Plan. Under the terms of the Agreement, Mr. DeKraai will be awarded 25,000 shares of restricted stock of the Registrant (the “Restricted Stock Shares”) promptly following the 2008 annual meeting of the Registrant’s stockholders, provided, that, at such annual meeting, such stockholders approve an amendment to the Willbros Group, Inc. 1996 Stock Plan to provide for an increase in the number of shares of common stock available for issuance under the Plan, as the Board shall recommend. All applicable restrictions on the Restricted Stock Shares will automatically lapse on November 20, 2010. Pursuant to the Agreement, in the event Mr. DeKraai’s employment is involuntarily terminated by InServ without cause, he will be entitled to receive an amount equal to his base salary specified in the Agreement, or his base salary in effect immediately before the involuntary termination, whichever is greater, for the period representing the remainder of the term of the Agreement. In the event of an early termination of the Agreement due to involuntary termination without cause, death or total disability as defined in the Agreement, all restrictions shall lapse on the Restricted Stock Shares and such award shall immediately vest.

     In conjunction with his appointment to the Board, on November 27, 2007, the Registrant entered into an Indemnification Agreement with Mr. DeKraai, the form of which has been filed as Exhibit 10.16 to the Registrant’s Registration Statement on Form S-1, Registration No. 333-5413. The Indemnification Agreement provides indemnity to the director against liabilities incurred in the performance of his duties to the fullest extent permitted by law.
