Ed Wiegele
Willbros Professional Services


Dear Ed:


As you know, the Willbros Board has authorized management to proceed with a sale of the Professional Services Segment.  As used in this letter, the reference to the Segment means the Professional Services Segment as it currently exists, excluding Willbros Engineering, LLC Willbros Heater Services, LLC, and the heater-related projects in Willbros Downstream, LLC.  In the event any or all of those businesses are added back and become a part of the sale of the Segment , or in the event any businesses or parts that currently form part of the Segment are removed from what is to be sold, you and Willbros agree that the Sale Price trigger numbers listed below in the Performance-based Award Section of this Letter will be adjusted upwards or downwards by an amount equal to Willbros’ good faith estimate of the target value for the business, businesses or parts that are added or removed, and this Letter will be amended or restated accordingly. 


We are committed to ensuring a smooth transition of the Segment to the new owner. We appreciate your and your teams’ leadership and dedication over the past several years and we want to maintain the continuity and financial performance of the Segment.  Therefore, we are offering you a performance-based award opportunity, as detailed below. 


		
	1.
	Sales Success Award




Provided you remain employed with (i) Willbros through the close of any sale of the Segment and (ii) with the buyer of the Segment, or its designee, through the Retention Period, and further provided you cooperate with Willbros management and promote in good faith the completion of sale to a buyer Willbros deems qualified, you will be paid a Sales Success Award of $475,000.  The “Retention Period” is the earlier of (i) completion of 60 days of employment with the buyer or its designee post-sale closing or (ii) the post-sale termination of your employment by the buyer.  The Sales Success Award will be earned upon close of a sale of the Segment at any price accepted by Willbros and completion of the Retention Period.  Notwithstanding the foregoing, you will not be paid a Sales Success Award if you earn a Performance-based Award under this Letter.  


		
	2.
	Performance-Based Award




In lieu of (and not in addition to) the Sales Success Award, provided you remain employed with (i) Willbros through the close of any sale of the Segment and (ii) with the buyer of the Segment, or its designee, through the Retention Period, and further provided you cooperate with Willbros management and promote in good faith the completion of sale to a buyer Willbros deems qualified, you will be eligible to earn a Performance-based Award upon achievement of a sale price for the Segment as set forth in the table below.  A Performance-based Award will be earned upon close of a sale of the Segment at price for the Segment of $80 million or above and completion of the Retention Period.
For clarity, if you earn a Performance-based Award, you will not be paid a Sales Success Award.









        Sale Price Targets                 Performance-based  Award Amount            
 
       $80 million                    $600,000
$90 million                    $712,500     
       $100 million                    $950,000
$110 million    or above            $1,187,500
(Amounts are not cumulative)
    
For a sale price of less than $80 million, you will receive the Sales Success Award and there will be no Performance-based Award.  For a sale price of $80 million or more, no Sales Success Award will be paid, but you will earn a Performance-based Award.  If a sale price of $80 million is achieved you will earn a Performance-based Award of $600,000.  If a sale price over $80 million but less than $90 million is achieved, the Performance-based Award will be calculated by linear interpolation starting with the Performance-based Award amount for a sale price of $80 million (i.e. $600,000) and ending with the Performance-based Award amount for a sale price of $90 million (i.e. $712,500).  The same linear interpolation process between sale-price targets will be used for higher sales prices, subject to a maximum $1,187,500 Performance-based Award.  


		
	3.
	Unvested Restricted Shares and RSUs




Per terms of your award agreements, your unvested restricted time-based shares will vest upon a sale of the Segment.  Your unearned performance-based restricted share units (“RSU”) will vest in accordance with the terms of your award agreements. 


		
	4.
	Other Terms




Payment of any Award you earn under this letter will be made to you within 30 days after the Award is earned and will be subject to government-imposed withholding.


This letter does not constitute a contract of employment nor does it affect your current employment status, and it is strictly confidential between you and Willbros.


Willbros may elect at any time in its sole discretion for any reason or for no reason not to sell the Segment.  In such event, you will not receive any award under this agreement.  


This agreement will terminate automatically on September 30, 2015 if the sale of the Segment is not completed by that date.


As you know, the Management Severance Plan (the “MSP”) in which you are a participant provides for a severance payment in the event of a termination of employment for other than cause in the event of a change of control of the Willbros parent entity.  It does not provide for a severance upon a termination of employment as a result of or after a sale of the Segment or any other businesses of Willbros.  For the avoidance of doubt, you acknowledge by signing below that no severance will be due to you under, and you waive any right to assert any claim under or pursuant to, the MSP as a result of a sale of the Segment.
