EXPLANATORY NOTE

This Amendment No. 1 to Form 10-K (the Amendment) amends Part III, Items 10 through
14, of the previously filed Annual Report on Form 10-K for the fiscal year ended December 31, 2017, originally filed on March 30, 2018 (the Original Filing) by Willbros Group, Inc.
(Willbros, WGI, we, us, our or the Company). We are filing this Amendment to include information previously omitted from the Original Filing in reliance on General Instruction
G(3) to Form 10-K, which provides that registrants may incorporate by reference certain information from a definitive proxy statement that involves the election of directors, provided that the definitive proxy
statement is filed with the Securities and Exchange Commission (SEC) within 120 days after the end of the fiscal year. Due to the Companys previously announced and pending merger with Primoris Services Corporation
(Primoris), the Company does not anticipate that a definitive proxy statement that involves the election of directors will be filed within 120 days of the end of the Companys fiscal year. Accordingly, Part III of the Original
Filing is hereby amended as set forth below.

In addition, as required by Rule 12b-15 under the
Securities Exchange Act of 1934, as amended, new certifications by our principal executive officer and principal financial officer are filed as exhibits under Item 15 of Part IV to this Amendment. Accordingly, Item 15 of the Original Filing is also
hereby amended as set forth below.

Except as stated herein, this Amendment does not reflect events occurring after the filing of the
Original Filing and no attempt has been made in this Amendment to modify or update other disclosures presented in the Original Filing. Among other things, forward-looking statements made in the Original Filing have not been revised to reflect events
that occurred or facts that became known to the Company after the Original Filing, and such forward-looking statements should be read in their historical context. Accordingly, this Amendment should be read in conjunction with the Original Filing and
the Companys other filings with the SEC subsequent to the filing of the Original Filing.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

Executive
Summary

The following Compensation Discussion and Analysis provides information related to the 2017 compensation of our executive
officers identified in the Summary Compensation Table, who we refer to as our Named Executive Officers, Named Executives or NEOs. We also refer to Michael J. Fournier, Jeffrey B. Kappel and Linnie A. Freeman as
our Corporate Executives, and Johnny M. Priest and Harry W. New as our Segment Presidents.

Overview

After considering our 2017 shareholder returns, our 2015-2017 shareholder returns under our long-term incentive awards and our recent financial
performance, which resulted in no payouts to the NEOs under our performance-based incentive program, we believe that our compensation program is aligned with the interests of our stockholders.

In 2017, the Compensation Committee of the Board of Directors, or Committee for purposes of this discussion, made a number of
decisions in an effort to further align executive pay with our recent performance:



| |  |  | The percentage of the long-term incentive, or LTI, award that is performance-based was increased significantly from 2016 levels. In 2016, 50 percent of the LTI award to Corporate Executives and
40 percent of the LTI award to Segment Presidents was performance-based. In 2017, 75 percent of the LTI award to the Corporate Executives and to Mr. Priest was performance-based, and 60 percent of the LTI award to Mr. New
was performance-based.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | For the third consecutive year, LTI awards were significantly curtailed in light of our low prevailing stock price and the unacceptable level of stockholder dilution that would have resulted if LTI awards had been
granted at comparable value levels to years prior to 2015.

| |  |  | In connection with his promotion to CEO on December 1, 2015, Mr. Fournier received an increase in his base salary from $475,000 to $613,000. However, Mr. Fournier waived the payment of his base salary
increase and continued to receive a base salary of $475,000 through May 31, 2017. Even after accepting his base salary increase 18 months after it was approved, Mr. Fourniers base salary remains well below the salaries of his two
predecessors.

| |  |  | In connection with his promotion to Chief Financial Officer on August 30, 2017, Mr. Kappel received a base salary of $300,000, significantly below that of his predecessor. In addition, Mr. Kappel received
an initial LTI award of 32,500 shares, 30,000 of which represented performance-based RSUs at target and 2,500 of which represented service-based restricted stock.

Stockholder Engagement and Committee Consideration of the 2017 Say-on-Pay Vote on Executive Compensation for 2016

Each year, we take into account the result
of the say-on-pay advisory vote cast by our stockholders on our executive compensation. At our 2017 Annual Meeting, we achieved a significant improvement in support,
with approval votes increasing from approximately 81 percent at the 2016 Annual Meeting to over 98 percent at the 2017 Annual Meeting. In addition, over the past year we have engaged with many of our stockholders to solicit their input on
a range of topics, including executive compensation. The Committee determined that, based on such discussions and given the increasing level of support, no substantive changes to our executive compensation policies for 2017 were necessary. If our
merger with Primoris is not completed, we intend to continue such dialogue with our stockholders, and the Committee intends to continue to make its executive compensation decisions, as it has in the past, by focusing on performance-based
compensation, gauging competitive practices and authorizing compensation that is within the range of what is deemed to be competitive and appropriate in our industry while taking into account our recent operating performance and financial condition.

Role of the Compensation Committee

The Committee has responsibility for discharging the Boards responsibilities with respect to compensation of our executives. In
particular, the Committee:



| |  |  | Reviews and approves corporate goals and objectives relevant to CEO compensation on an annual basis;
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | Evaluates the CEOs performance in light of those goals and objectives;
| | - |  | -----------------------------------------------------------------------

| |  |  | Determines and approves the CEOs compensation based on this evaluation;
| | - |  | ------------------------------------------------------------------------



| |  |  | Approves non-CEO executive compensation;
| | - |  | ----------------------------------------



| |  |  | Approves and administers incentive compensation plans and equity-based plans; and
| | - |  | ---------------------------------------------------------------------------------



| |  |  | Monitors compliance of directors and executive officers with our Stock Ownership and Retention Policy.
| | - |  | ------------------------------------------------------------------------------------------------------

Pursuant to its charter, the Committee has the sole authority to retain and terminate compensation consultants and internal and external legal, accounting and
other advisors, including sole authority to approve the advisors fees and other engagement terms.

Role of the CEO in Compensation Decisions

The CEO periodically reviews the performance of each of the Named Executives, excluding himself, develops preliminary recommendations
regarding salary adjustments and annual and long-term award amounts, and provides these recommendations to the Committee. The Committee can exercise its discretion in modifying any recommendation and makes the final decisions.

Role of the Compensation Consultant

The
Committee has retained Mercer (US) Inc. to serve as its independent consultant, and in its role Mercer:



| |  |  | Provides executive and director compensation consulting services to the Committee;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | Attends Committee meetings;
| | - |  | ---------------------------



| |  |  | Reports directly to the Committee on matters relating to compensation for our Named Executives;
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | Participates in executive sessions of the Committee without Named Executives present; and
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | Provides advice and analysis to the Committee on design and level of executive and director compensation.
| | - |  | ---------------------------------------------------------------------------------------------------------

In
connection with its services to the Committee, Mercer works with executive management and our Corporate Human Resources group to formalize proposals for the Committee.

The Committee has assessed the independence of Mercer pursuant to SEC and New York Stock Exchange rules and concluded that Mercers work
for the Committee does not raise any conflict of interest.

Compensation Philosophy and Objectives

As a provider of construction, maintenance and facilities development services to the oil and gas and power industries, our long-term success
has depended on our ability to attract, motivate and retain highly talented individuals at all levels of the organization in order to develop and expand our businesses and execute our business strategies.

The Committee has based its executive compensation decisions on the same objectives that guide us in establishing all of our compensation
programs:



| |  |  | Compensation should be based on the level of job responsibility, individual performance and Company performance.As employees progress to higher levels in the organization and are more able to affect our results,
an increasing proportion of their pay should be linked to the Companys and/or segments overall performance and to stockholder returns.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | Compensation should reflect the value of the job in the marketplace.To attract and retain a highly skilled work force, we must remain competitive with the compensation of other premier employers who compete with
us for talent.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Compensation should incentivize and reward annual and long-term performance. Our programs should deliver compensation in the top tier when our employees and our Company perform accordingly; likewise, where
individual performance falls short of expectations and/or our performance lags the industry, the programs should deliver lower-tier compensation.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our objectives of pay for performance and retention must be balanced. Compensation should promote retention of high-performing executives while aligning the interests of our executives with those of our
stockholders. Even in periods of downturns in our performance, the programs should continue to ensure that successful, high-achieving employees will remain motivated and committed to us.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Compensation should foster the long-term focus required for success in our industry.
| | - |  | ------------------------------------------------------------------------------------

Setting
Executive Compensation

A significant percentage of total compensation is allocated to incentives as a result of the philosophy
mentioned above. There is no pre-established policy or target for the allocation between either cash and equity or annual and long-term incentive compensation. Rather, the Committee reviews competitive
information provided by Mercer and managements recommendations to determine the appropriate level and mix of incentive compensation.

For Named Executives, the Committee generally targets total direct compensation, consisting of base salary, the target annual incentive award
and the annual long-term incentive grants, at a level which is designed to be competitive with compensation paid to similarly situated executives of companies comprising a peer group of publicly traded companies that have financial and operating
characteristics and service markets similar to ours.

With the assistance of Mercer, the Committee reviews the composition of the peer
group periodically to ensure the companies are relevant for comparative purposes. For purposes of setting 2017 compensation, the peer group consisted of the following 13 companies in the construction and engineering, oil and gas equipment and
services, electrical transmission and distribution services and environmental and facilities services industries (the 2017 Peer Group):



|                          |  |                              
|------------------------- |  | -----------------------------
|Aegion Corporation        |  | Northwest Pipe Company       
|Comfort Systems USA       |  | Orion Group Holdings, Inc.   
|Granite Construction      |  | Sterling Construction Company
|Great Lakes Dredge & Dock |  | Team Inc.                    
|Layne Christensen         |  | Tetra Tech, Inc.             
|Matrix Service Company    |  | TRC Companies, Inc.*         
|MYR Group                 |  |                              



|* | TRC Companies, Inc. was included in the 2017 Peer Group until it was taken private in June 2017.
|- | ------------------------------------------------------------------------------------------------

In selecting
the 2017 Peer Group, the Committee considered various peer selection criteria, including: industries in which the company operates, company size (with specific focus on revenue), markets served, market value, market value to revenue ratio, and total
assets. In addition, the Committee considered the competitive market for executive talent and gave special consideration to those companies from which we may recruit talent or to which we may lose talent.

Following is a discussion of the Committees considerations in establishing each of the compensation components for the
current NEOs.

Base Salary

The level of base salary paid is determined on the basis of performance, experience, job responsibility and such other factors as may be
appropriately considered by the Committee. Each year, the Committee reviews the base salaries of the Named Executives and considers salary adjustments based on individual performance, our overall

financial results, competitive position relative to the marketplace, duration of time since the last salary increase and industry merit practices. The Committee uses the independent consultant
report with respect to the marketplace in general and the base salaries of executives within the 2017 Peer Group, including amounts budgeted for merit increases within our industry, in order to establish base salaries which are competitive in the
marketplace.

Mr. Fournier was promoted to the position of Chief Executive Officer effective December 1, 2015 and maintained his
previous duties as President and Chief Operating Officer. As part of his promotion, Mr. Fourniers base salary was increased from $475,000 to $613,000, effective December 1, 2015. However, Mr. Fournier elected to waive the
payment of the increase in his base salary for an 18-month period ending May 31, 2017. Mr. Kappel was promoted to the position of Senior Vice President and Chief Financial Officer on August 30,
2017. As part of his promotion, Mr. Kappels base salary was increased from $221,000 to $300,000, effective August 30, 2017. Ms. Freeman was promoted to the position of Senior Vice President and General Counsel, effective
April 1, 2016. On the first anniversary of her promotion, the Committee approved an increase in her base salary from $325,000 to $350,000. In light of our disappointing performance in 2016 and as part of our efforts to control our overhead
expenses, the base salaries of the other Named Executives were not increased in 2017. The following table shows the base salaries for each of the Named Executives as of December 31, 2016 and 2017 and the percentage change in base salary, if
any:

|* | The amount of $555,500 shown in the Summary Compensation Table as salary for Mr. Fournier in 2017 represents an annual salary of $475,000 for the first five months of the year and an annual salary of $613,000 for
the remainder of the year. The amount of $475,000 shown in the Summary Compensation Table as salary for Mr. Fournier in 2016 represents the amount actually paid to Mr. Fournier in 2016 due to his election to waive the increase in his base
salary that the Committee approved in December 2015.

Annual Incentive Compensation

Management Incentive Compensation (MIC) Program.Annual cash incentive awards for key employees are determined in accordance
with our MIC Program, in which each of our Named Executives participates. The award opportunity established for the 2017 MIC Program for our NEOs, as a percent of base salary, was as follows:



|                 |  |           |   |   |        |  |    |         |  |  |     |

|NEO              |  | Threshold |   |   | Target |  |    | Maximum | 
|Michael Fournier |  |           | 0 | % |        |  | 50 | %       |  |  | 200 | %
|Jeffrey Kappel   |  |           | 0 | % |        |  | 50 | %       |  |  | 150 | %
|Johnny Priest    |  |           | 0 | % |        |  | 50 | %       |  |  | 150 | %
|Linnie Freeman   |  |           | 0 | % |        |  | 50 | %       |  |  | 120 | %
|Harry New        |  |           | 0 | % |        |  | 50 | %       |  |  | 150 | %

Under the MIC Program, financial and operational performance measures are comprised of threshold, target and
maximum performance levels. Payouts begin for performance above the threshold level for financial or operational measures. No amount is paid on an MIC Program award for performance at or below the threshold performance level of a financial or
operational measure component. The Committee believed that improved financial performance was critical to our future success. Accordingly, for 2017, the Committee chose to use Adjusted EBITDA as the sole performance measure for our MIC Program for
the Corporate Executives and Operating Income as the sole performance measure for our MIC Program for the Segment Presidents. Adjusted EBITDA is defined as income (loss) from continuing operations before interest expense, income tax expense
(benefit) and depreciation and amortization (adjusted for certain unusual items) and is an important measure for comparing normalized operating results with corresponding historical periods and with the operational performance of other companies in
our industry. Operating Income is an important measure of our operating profit before interest and taxes and is defined as contract income (loss) minus amortization of intangibles, general and administrative expenses and other charges.

When determining performance ranges for each goal, the Committee first considered our 2016
performance and the 2017 budget approved by our Board of Directors. The Committee then focused discussions on the appropriate balance between our ability to achieve various performance levels and the appropriate amount of stretch performance to
build into each goal and established challenging goals for 2017.

The specific 2017 Adjusted EBITDA performance measure at the Corporate
level was as follows ($ in millions):



|                    |  |           |       |  |        |   |      |         |  |   |       | 
|------------------- |  | --------- | ----- |  | ------ | - | ---- | ------- |  | - | ----- | 
|Performance Measure |  | Threshold |       |  | Target |   |      | Maximum | 
|Adjusted EBITDA     |  | $         | 37.08 |  |        | $ | 41.2 |         |  | $ | 55.56 | 

The Companys actual Adjusted EBITDA for 2017 was $(70.9) million.

In 2017, the Committee also authorized Operating Income performance measures at the segment level for the Segment Presidents. Segment level
targets were authorized for Mr. Priest, who served as President of our Utility T&D segment and Mr. New, who served as President of our Oil& Gas segment.

The MIC Program award pool for the Corporate Executives is funded out of a percentage of Adjusted EBITDA in excess of a threshold amount
($37.08 million in 2017) and for the Segment Presidents is funded out of a percentage of consolidated Operating Income in excess of a threshold amount ($18.1 million in 2017). If Adjusted EBITDA or consolidated Operating Income falls below
these levels for the performance year, bonuses are not paid to the Corporate Executives in the case of Adjusted EBITDA, or to the Segment Presidents in the case of Operating Income. Adjusted EBITDA for 2017 was $(70.9) million, which was below the
threshold level. Operating Income for 2017 was $(91.3) million which was also below the threshold level. Accordingly, no bonuses were paid to the NEOs in respect of the 2017 MIC Program, as shown in the following table.

Long-term Incentive Compensation

The Willbros Group, Inc. 2017 Stock and Incentive Compensation Plan (the 2017 Stock Plan), permits the Committee to grant various
long-term incentive awards, including stock options, stock appreciation rights, restricted stock and restricted stock units, performance shares, performance units, and long-term cash-based awards to Named Executives and our key management employees.

Under the 2017 LTI award program:



| |  |  | 75 percent of the total LTI award to the Corporate Executives and to Mr. Priest is performance-based and 25 percent is service-based.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 60 percent of the total LTI award to Mr. New is performance-based and 40 percent is service-based.
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | The performance period for performance-based awards is three years, with any earned award paid in March of the calendar year following the end of the three-year performance period.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Any payouts for performance-based awards are determined solely by the Companys relative and absolute TSR performance.
| | - |  | ----------------------------------------------------------------------------------------------------------------------



| |  |  | Service-based awards vest in equal increments on the anniversary date of the award over a period of four years.

2017 Long-term Incentive Awards.In 2017, the Committee granted equity awards in the form
of service-based restricted stock and performance-based restricted stock units (RSUs), to our Named Executives. Performance-based RSU awards provide an opportunity for the award recipient to receive up to 200 percent of the target
number of performance-based RSUs granted if performance is achieved at the maximum level. Performance-based RSUs are only earned if we attain specific TSR results. We measure both relative TSR against our peers and absolute TSR as interdependent
measures in determining the performance level achieved and the number of performance-based awards earned. Including absolute TSR ensures that we are delivering value to our stockholders, not simply performing well against our peers. Our relative TSR
may rank at the top of our peers; however, if we have not delivered value to our stockholders, awards will be limited. Under this performance evaluation structure, which we refer to as the TSR Performance Matrix, for the three-year period covering
calendar 2017 through 2019, a maximum payout is achieved only if we finish the period ranked in the top two companies against our 2017 Peer Group and achieve annualized absolute stock price growth of at least 35 percent from the
beginning price for the performance period, which was $3.03. Moreover, if our relative TSR performance places us among the top two companies against our 2017 Peer Group but our stock price does not grow over the performance period above the
beginning price of $3.03, then payouts are capped at target.

The following table shows the number of service-based restricted shares and
performance-based RSUs awarded in 2017 to each of the NEOs:

In light of our low prevailing stock price and the unacceptable level of stockholder dilution that would have
resulted from LTI awards commensurate with the grant date value of awards in years prior to 2015, the latest year when the grant date fair value of our awards was generally commensurate with median grant value levels of our peers, the total number
of shares of restricted stock and performance-based RSUs awarded to each of the NEOs in 2017 was significantly curtailed. In order to provide a meaningful long-term incentive opportunity, the Committee first determined the grant date fair value of
the award that would be appropriate for each executive in light of peer group data and other factors. Then, in order to minimize dilution to our stockholders, the Committee assumed a stock price of $4.00 per share to compute share grants to our
NEOs. This assumed stock price was significantly higher than the closing stock price of $2.47 per share on the June 1, 2017 grant date. This methodology resulted in grant date values of the 2017 LTI awards that were less than the value that the
Committee would have awarded but for the dilution concerns.

2015 Performance-Based LTI Awards. The following tables show
(i) the TSR Performance Matrix for the three-year period that ended December 31, 2017 and (ii) the target number of performance-based RSUs awarded to our NEOs in 2015, other than Mr. Kappel, Ms. Freeman and Mr. New, who
did not receive an award of performance-based RSUs in 2015. As shown in the table, no performance-based RSU awards were earned as a result of performance over the 2015-2017 period.

Perquisites

We provide our Named Executives with a limited number of perquisites that the Committee believes are reasonable and in line with our overall
compensation program and better enable us to attract and retain talented employees for executive positions. The Committee periodically reviews the type and levels of perquisites provided to our Named Executives.



| |  |  | We reimbursed Mr. Fournier for his commuting expenses on commercial airlines from Mr. Fourniers principal residence in Canada to our headquarters in Houston, Texas during 2017. We also reimbursed
Mr. Priest for his commuting expenses from his principal residence in North Carolina to the headquarters of our Utility T&D segment in Fort Worth, Texas.

The Committee determined that the payment of
commuting expenses and housing and auto expenses for certain executives who commute from remote locations was necessary in order to retain the services of these key executives.

Compensation of Former Executive

The
base salary of Van A. Welch, our former Executive Vice President and CFO, was $475,000 during 2017, unchanged from 2016. Mr. Welch received no cash annual incentive award for 2017. Mr. Welchs annual LTI award in June 2017 consisted
of 60,000 shares of performance-based RSUs at target (120,000 shares at maximum) and 20,000 shares of service-based restricted stock. In connection with his voluntary resignation:



| |  |  | Mr. Welch received no severance under the 2010 Willbros Group, Inc. Management Severance Plan for Executives (the Management Severance Plan for Executives).
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | All of Mr. Welchs outstanding performance-based RSU awards were forfeited.
| | - |  | ---------------------------------------------------------------------------



| |  |  | In connection with his agreement to delay the effective date of his resignation until August 30, 2017 and to ensure an orderly transition of his responsibilities, the Committee approved the accelerated vesting of
46,458 shares of Mr. Welchs service-based restricted stock, representing all of his service-based stock awards for 2015 and a portion of his service-based stock awards for 2016, following the effective date of his resignation and upon
satisfaction of certain conditions. These conditions were not satisfied, and the 46,458 shares of service-based restricted stock were ultimately forfeited. Mr. Welch also forfeited an additional 33,125 shares of service-based restricted stock,
representing a portion of his service-based stock awards for 2016 and all of his service-based stock award for 2017.

Stock Ownership and
Retention Policy

In an effort to further align the interests of our executives and directors with our stockholders, the Board of
Directors has approved stock ownership guidelines for the executive officers and directors that require them to acquire and retain a significant financial stake in our common stock. The purpose of the policy is to require our executive officers and
directors to retain a number of shares equal to substantially all of the after-tax value of their recent awards, while enabling these individuals to dispose of a sufficient number of shares to cover the tax
liability associated with the vesting of such shares.

Policy on Hedging and Pledging of Company Securities

Hedging transactions may permit a director, officer or employee to continue to own Willbros securities obtained through employee benefit plans
or otherwise, but without the full risks and rewards of ownership. When that occurs, the director, officer or employee may no longer have the same objectives as our other stockholders. Our Policy for Securities Trades specifically prohibits our
directors, Named Executives and other employees from engaging in any hedging activities with respect to our securities.

Securities held
in a margin account as collateral for a margin loan may be sold by the broker without the customers consent if the customer fails to meet a margin call. Similarly, securities pledged as collateral for a loan may be sold in foreclosure if the
borrower defaults on the loan. Because a margin sale or foreclosure sale may occur at a time when the pledgor is aware of material non-public information or otherwise is not permitted to trade in Willbros
securities, our Policy for Securities Trades prohibits directors, Named Executives and other key employees from holding Willbros securities in a margin account or otherwise pledging Willbros securities.

Severance Plans

In 2010, the Board of
Directors adopted the Management Severance Plan for Executives and the Willbros Group, Inc. 2010 Management Severance Plan for Senior Management (the Senior Management MSP and, collectively with the Management Severance Plan for
Executives, the U.S. Severance Plans). The U.S. Severance Plans were adopted to provide assurance of severance benefits for terminated executive employees while better aligning our severance policies with current compensation trends. In
2014, the Board of Directors adopted the Management Severance Plan for Canadian Executives (the Canadian MSP for Executives and, collectively with the U.S. Severance Plans, the Severance Plans). Mr. Kappel,
Mr. Priest and Ms. Freeman are participants in the Management Severance Plan for Executives. Prior to his resignation in January 2018, Mr. New was a participant in the Senior Management MSP. Mr. Fournier is a participant in the
Canadian MSP for Executives. Under the Severance Plans, payment of change of control severance benefits is conditioned upon the occurrence of a double trigger, in which the executive is terminated not for cause or resigns for good
reason within one year after a change of control. In addition, the U.S. Severance Plans provide that if the payments and benefits otherwise required under the plan would constitute an excess parachute payment under the Internal
Revenue Code, then the payments and benefits will be cut back so that no portion of the amounts received by a participant will be subject to the excise tax imposed under Section 4999 of the Internal Revenue Code.

Clawback Policy

The Committee has adopted a clawback policy, which is intended to be interpreted in a manner consistent with any applicable rules or
regulations to be adopted by the SEC or the New York Stock Exchange as contemplated by the Dodd-Frank Act. The policy provides that in the event of an accounting restatement due to material non-compliance with
the financial reporting requirements under U.S. federal securities laws, the Committee has the right to use reasonable efforts to recover from any of our current or former executive officers who received incentive-based compensation during the
three-year period preceding the date on which we are required to prepare an accounting restatement any excess incentive-based compensation awarded as a result of the misstatement.

Compensation Program as it Relates to Risk

We have reviewed our compensation policies and practices for both executives and non-executives as they
relate to risk and have determined that they are not reasonably likely to have a material adverse effect on us. In reaching this conclusion, we considered the various elements of our compensation program that are designed to help mitigate excessive
risk taking, including:



| |  |  | Components of Compensation: We use a mix of compensation elements including base salary, annual incentives and long-term incentives to avoid placing too much emphasis on any one component of compensation.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Annual Incentive: Our MIC Program does not allow for unlimited payouts. For the 2017 program, annual incentive payments cannot exceed 200 percent of base salary for Mr. Fournier, 150 percent of base salary for Messrs.
Kappel, Priest and New, and 120 percent of base salary for Ms. Freeman.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Equity Awards: Our long-term incentive awards drive a long-term perspective and typically vest over a period of three or four years. Our performance-based long-term incentive awards are capped and cannot exceed
200 percent of target levels.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Committee Oversight: The Committee reviews and administers all awards under annual and long-term incentive plans.
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | Performance Measures: Our performance goal setting process is aligned with our business strategy, our mission, vision and values and the interests of our stockholders.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Clawback Policy: We have the ability to recover any excess incentive-based compensation awarded to any of our executive officers as a result of an accounting restatement due to material
non-compliance with the reporting requirements under federal securities laws.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Stock Ownership and Retention Policy: Our Stock Ownership and Retention Policy requires our senior management to maintain a significant portion of their personal wealth in our common stock for the duration of their
employment with us.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Hedging Policy: Our hedging policy requires our senior management to retain the full risks and rewards associated with owning our common stock with respect to all of the shares they are required to retain.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our compensation program is designed to motivate our Named Executives and other Company officers to achieve business
objectives that generate stockholder returns and to encourage behaviors that are consistent with our values.

Policy Regarding Tax Deductibility of Executive Compensation

Section 162(m) of the Internal Revenue Code generally limits to $1 million annually the federal income tax deduction that a publicly
held corporation may claim for compensation payable to certain of its respective current and former executive officers, but that deduction limitation historically did not apply to performance-based compensation that met certain requirements. As
part of the tax legislation passed in December 2017, Section 162(m) was amended, effective for taxable years beginning after December 31, 2017, to expand the scope of executive officers subject to the deduction limitation and also to
eliminate the performance-based compensation exception, though the exception generally continues to be available on a grandfathered basis to compensation payable under a written binding contract in effect on November 2, 2017.

In determining compensation for our executive officers, the Committee considers the extent to which the compensation is deductible, including
the effect of Section 162(m). In prior years, the Committee generally sought to structure our executive incentive compensation awards so that they qualified as performance-based compensation exempt from the Section 162(m) deduction
limitation where doing so was consistent with our compensation objectives, but it reserved the right to award nondeductible compensation and often did so. The Committee continues to evaluate the changes to Section 162(m) and their
significance to our compensation programs, but in any event its primary focus in its compensation decisions will remain on furthering our business objectives and not on whether compensation is deductible. The Committee has not at this time made any
significant changes to our executive compensation program in response to the tax code changes.

Compensation Committee Report

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis included in this Form 10-K with management of Willbros, and based on such review and discussions, the Compensation Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this Form 10-K.

CEO Pay Ratio

For 2017, the annual total compensation of our CEO was 22 times that of the median of the annual total compensation of all employees (other
than our CEO), based on annual total compensation of $1,432,954 for the CEO, as reported in the Summary Compensation Table included above, and $64,790 for the median employee. This calculation is based on our employee population of 3,919 as of
December 24, 2017, which included all 1,362 of our non-U.S. employees, all of whom are located in Canada.

To identify the median employee, we used a consistently applied compensation measure (CACM)
of W-2, Box 5 earnings for our U.S. population (and equivalent wages for our non-U.S. population) for fiscal 2017, annualizing the CACM for those
employees hired during 2017. We used average annual exchange rates to convert the CACM of the non-U.S. employees to U.S. currency.

This pay ratio is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll and employment records and the
methodology described above. The SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employees annual total compensation allow companies to adopt a variety of methodologies, to apply certain
exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices. As such, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies may have different
employment and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

Potential Payments Upon Termination or Change in Control

The following tables show potential payments to our named executive officers under existing contracts, agreements, plans or arrangements,
whether written or unwritten, for various scenarios involving a change in control or termination of each of such named executive officers, assuming a December 31, 2017 termination date and, where applicable, using the closing price of our
common stock of $1.42 (as reported on the New York Stock Exchange) as of Friday, December 29, 2017. These amounts are estimates only. The actual amounts to be paid out can only be determined at the time of such officers separation from
us.

|(1) | Other than allowing them to participate in ERISA plans we sponsor, we do not provide retirement benefits to senior executives.
|--- | ------------------------------------------------------------------------------------------------------------------------------

|(2) | Under our Management Severance Plan for Executives-Canada, if Mr. Fourniers employment is terminated other than for cause by us prior to a change of control and prior to December 1, 2018,
Mr. Fournier would be entitled to a payment equal to two times the greater of his base compensation immediately before the change in control or on the date of separation from service.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(3) | Under our Management Severance Plan for Executives-Canada, Mr. Fournier would be entitled to a payment equal to two times the sum of (i) the greater of his base compensation immediately before the change in
control or on the date of separation from service and (ii) the largest annual cash bonus he received in the 36 months before the change in control or on the date of separation from service (he received no cash bonus between January 1, 2015
and December 31, 2017); plus one times his target cash bonus for the year of his termination. His target cash bonus for 2017 under our Management Incentive Compensation Program was one-half his base
salary, $306,500.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(4) | Under the award agreements whereby Mr. Fournier was awarded shares of time-based Restricted Stock Units (RSUs), he would be entitled to the accelerated vesting of 123,382 RSUs.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(5) | Under the award agreements whereby Mr. Fournier was awarded 337,500 performance-based RSUs, if (i) prior to a change of control, Mr. Fourniers employment is terminated by us other than for cause, or
(ii) Mr. Fournier dies or becomes disabled, in each case on a date which is prior to the end of the performance period, the RSUs would vest pro rata based on the number of months served in relation to the total number of months in the
performance period and only to the extent that the performance metric (relative and absolute total stockholder return, or TSR) is ultimately satisfied. Based on our relative and absolute TSR for the periods January 1, 2015 to
December 31, 2017, January 1, 2016 to December 31, 2017, and January 1, 2017 to December 31, 2017, we have assumed that there will be no payout on any of his unvested RSUs.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(6) | Under the award agreements whereby Mr. Fournier was awarded 337,500 performance-based RSUs, if, within one year following a change of control, Mr. Fourniers employment is terminated by us other than for
cause or Mr. Fournier resigns for good reason, he would be entitled to the accelerated vesting of all such performance-based RSUs at target. However, in January 2018, the Committee certified that there would be no payout on the
performance-based RSUs awarded in 2015. Accordingly, we have assumed that the vesting of only the 312,500 of performance-based RSUs awarded in 2016 and 2017 would be accelerated.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(7) | Under our Management Severance Plan for Executives-Canada, Mr. Fournier would be entitled to continued coverage for 12 months for himself and his eligible dependents for health and dental insurance and
continued life insurance coverage for 12 months for himself (the total cost for coverage less the amounts paid by him under our plans as an employee).

|(2) | Under our Management Severance Plan for Executives, Mr. Kappel would be entitled to an amount equal to his annual base compensation.
|--- | ------------------------------------------------------------------------------------------------------------------------------------

|(3) | Under our Management Severance Plan for Executives, Mr. Kappel would be entitled to a payment equal to two times the sum of (i) the greater of his base compensation immediately before the change in control or
on the date of separation from service and (ii) the largest annual cash bonus he received in the 36 months before the change in control or on the date of separation from service (he received no cash bonus between January 1, 2015 and
December 31, 2017); plus one times his target cash bonus for the year of his termination. His target cash bonus for 2017 under our Management Incentive Compensation Program was one-half his base salary,
$150,000.

|(5) | Under the award agreements whereby Mr. Kappel was awarded 30,000 performance-based RSUs, if (i) prior to a change of control, Mr. Kappels employment is terminated by us other than for cause, or
(ii) Mr. Kappel dies or becomes disabled, in each case on a date which is prior to the end of the performance period, the RSUs would vest pro rata based on the number of months served in relation to the total number of months in the
performance period and only to the extent that the performance metric (relative and absolute total stockholder return, or TSR) is ultimately satisfied. Based on our relative and absolute TSR for the period January 1, 2017 to
December 31, 2017, we have assumed that there will be no payout on any of his unvested RSUs.

|(6) | Under the award agreement whereby Mr. Kappel was awarded 30,000 performance-based RSUs, if, within one year following a change of control, Mr. Kappels employment is terminated by us other than for cause
or Mr. Kappel resigns for good reason, he would be entitled to the accelerated vesting of all such performance-based RSUs at target.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(7) | Under our Management Severance Plan for Executives, Mr. Kappels medical/dental and life insurance coverage would continue for 12 months.

December 31, 2017, January 1, 2016 to December 31, 2017, and January 1, 2017 to December 31, 2017, we have assumed that there will be no payout on any of his unvested RSUs.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(6) | Under the award agreements whereby Mr. Priest was awarded 90,000 performance-based RSUs, if, within one year following a change of control, Mr. Priests employment is terminated by us other than for cause
or Mr. Priest resigns for good reason, he would be entitled to the accelerated vesting of all such performance-based RSUs at target. However, in January 2018, the Committee certified that there would be no payout on any of his
performance-based RSUs awarded in 2015. Accordingly, we have assumed that the vesting of only the 65,000 of performance-based RSUs awarded in 2016 and 2017 would be accelerated.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(7) | Under our Management Severance Plan for Executives, Mr. Priest would be entitled to continued coverage for twelve months for himself and his eligible dependents for health and dental insurance and continued life
insurance coverage for twelve months for himself (the total cost for coverage less the amounts paid by him under our plans as an employee).

|(1) | Other than allowing them to participate in ERISA plans we sponsor, we do not provide retirement benefits to senior executives.
|--- | ------------------------------------------------------------------------------------------------------------------------------

|(2) | Under our Management Severance Plan for Executives, Ms. Freeman would be entitled to an amount equal to her annual base compensation.
|--- | -------------------------------------------------------------------------------------------------------------------------------------

|(3) | Under our Management Severance Plan for Executives, Ms. Freeman would be entitled to a payment equal to two times the sum of (i) the greater of her base compensation immediately before the change in control or
on the date of separation from service and (ii) the largest annual cash bonus she received in the 36 months before the change in control (Ms. Freeman received a $25,000 cash bonus in 2015); plus one times her target cash bonus for the year
of her termination. Her target cash bonus for 2017 under our Management Incentive Compensation Program was one-half her base salary, $175,000.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(4) | Under the award agreements whereby Ms. Freeman was awarded shares of restricted stock, she would be entitled to the accelerated vesting of 32,500 shares of restricted stock.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(5) | Under the award agreements whereby Ms. Freeman was awarded 60,000 performance-based RSUs, if (i) prior to a change of control, Ms. Freemans employment is terminated by us other than for cause, or
(ii) Ms. Freeman dies or becomes disabled, in each case on a date which is prior to the end of the performance period, the RSUs would vest pro rata based on the number of months served in relation to the total number of months in the
performance period and only to the extent that the performance metric (relative and absolute total stockholder return, or TSR) is ultimately satisfied. Based on our relative and absolute TSR for the periods January 1, 2016 to
December 31, 2017, and January 1, 2017 to December 31, 2017, we have assumed that there will be no payout on any of her unvested RSUs.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(6) | Under the award agreements whereby Ms. Freeman was awarded 60,000 performance-based RSUs, if, within one year following a change of control, Ms. Freemans employment is terminated by us other than for
cause or Mr. Freeman resigns for good reason, she would be entitled to the accelerated vesting of all such performance-based RSUs at target.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(7) | Under our Management Severance Plan for Executives, Ms. Freeman would be entitled to continued coverage for twelve months for herself and her eligible dependents for health and dental insurance and continued life
insurance coverage for twelve months for herself (the total cost for coverage less the amounts paid by her under our plans as an employee).

December 31, 2017, and January 1, 2017 to December 31, 2017, we have assumed that there would be no payout on any of his unvested RSUs.

Management Severance Plans.

U.S. Plan for Executives. In October 2010, we established the Willbros Group, Inc. 2010 Management Severance Plan for Executives (the
Management Severance Plan for Executives). Messrs. Kappel and Priest and Ms. Freeman are participants in this Plan. The initial term of this Plan ended on December 31, 2010. On the last day of the initial term, and on each
successive anniversary of such date, the term of this Plan is extended automatically for an additional successive one-year term, unless we give notice to the participants that no such extension shall occur.

The Management Severance Plan for Executives provides that a participant whose employment is terminated other than for cause by us or who
voluntarily terminates his employment for good reason within one year after a change in control of us has occurred, shall be entitled to severance compensation equal to:



| |  |  | 200 percent of the greater of the participants base compensation in effect immediately prior to the date of the change in control or the participants base compensation in effect on the date of the
termination of employment;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 200 percent of the participants greatest annual cash bonus received during the 36-month period ending on the date of the change in control;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the aggregate annual incentive plan target opportunity that could have been earned in the year in which the termination of employment occurs, prorated for the amount of time served in the year in which the termination
occurred;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the actual cost incurred by the participant for health continuation coverage for a period of 12 months from the date of termination, less the cost the participant would have incurred for comparable coverage if the
participant had remained an employee of us; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the participants cost for life insurance benefits, for a period of 12 months following termination of employment, under life insurance benefit plans maintained by us immediately prior to the participants
termination.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Good reason means, generally, a reduction in the participants annual base compensation, a
relocation of the participants place of employment by 50 or more miles, a significant reduction in the nature or scope of a participants authorities or duties or a successor companys failure to honor this Plan.

The Management Severance Plan for Executives provides that a participant whose employment is terminated other than for cause by us prior to a
change in control shall be entitled to severance compensation equal to 100 percent of the participants base salary in effect on the date of the termination of employment.

The Management Severance Plan for Executives provides that if the payments and benefits otherwise required under this Plan would constitute an
excess parachute payment under the Internal Revenue Code, then the payments and benefits will be reduced so that no portion of the amounts received by a participant will be subject to the excise tax imposed under Section 4999 of the
Internal Revenue Code.

During the term of the Management Severance Plan for Executives and for a period of one year following the
termination of employment of a participant, regardless of the reason for the termination, such participant is prohibited from, among other things, competing with the businesses of the Company or its affiliates, causing or attempting to cause any
employee, director or consultant of the Company or its affiliates to terminate his relationship with the Company or such affiliate, or soliciting business from established customers of the Company or

such affiliate. This Plan also requires, among other things, a participant to keep our trade secrets and proprietary information confidential, restricts the participant from disparaging or
criticizing us and restricts us from disparaging or criticizing the participant.

U.S. Plan for Senior Management.In October 2010,
we established the Willbros Group, Inc. 2010 Management Severance Plan for Senior Management (the MSP for Senior Management). Mr. New was a participant in this Plan prior to his resignation on January 12, 2018. The initial term
of the MSP for Senior Management ended on December 31, 2010. On the last day of the initial term, and on each successive anniversary of such date, the term of the MSP for Senior Management is extended automatically for an additional successive one-year term, unless we give notice to the participants that no such extension shall occur. The MSP for Senior Management provides severance compensation substantially equivalent to the benefits described above for
certain executive officers under the Management Severance Plan for Executives, except that the 200 percent payments described above relating to a change in control of us shall only be 100 percent.

Canadian Plan for Executives. In October 2014, we established the Willbros Group, Inc. Management Severance Plan for Executives -
Canada (as amended, the Canadian MSP for Executives). Mr. Fournier is a participant in this Plan. The initial term of the Canadian MSP for Executives ended on December 31, 2014. On the last day of the initial term, and on each
successive anniversary of such date, the term of the Canadian MSP for Executives is extended automatically for an additional successive one-year term, unless we give notice to the participants that no such
extension shall occur. The Canadian MSP for Executives provides severance compensation substantially equivalent to the benefits described above for certain executive officers under the Management Severance Plan for Executives, except that (a) a
participant whose employment is terminated other than for cause by us prior to a change in control and before December 1, 2018 will be entitled to severance compensation equal to 200% of the participants annual base salary in effect on
the date of the termination of employment and (b) a participant whose employment is terminated other than for cause by us prior to a change in control and on or after December 1, 2018 will be entitled to severance compensation equal to
100% of the participants annual base salary in effect on the date of the termination of employment and 100% of the participants greatest annual cash bonus received during the 36-month period ending
on the date of the termination of employment. We have waived Mr. Fourniers compliance with the non-competition provisions of the Canadian MSP for Executives and the Management Severance Plan for
Executives in the event that Mr. Fournier voluntarily leaves us on or after December 1, 2018.

2010 Stock Plan. Under our
2010 Stock Plan, all outstanding awards become fully exercisable and free of all restrictions, and, in the case of performance-based awards, the target payout opportunity shall be deemed to be fully earned, in the event of a change of control of us,
as defined in such plan, unless otherwise provided in the award agreement or specifically prohibited by law or by the rules and regulations of any national securities exchange. However, no accelerated vesting, lapsing of restrictions or payment of
awards will occur if the Compensation Committee reasonably determines in good faith before the occurrence of a change of control that the award will be honored or assumed, or new rights substituted for the award by any successor, and the alternative
award:



| |  |  | will be based on stock that will be publicly traded in any established U.S. trading market;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | provides the participant with rights and terms that are substantially equivalent or superior to the rights and terms of the existing award;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | will have at least substantially equivalent economic value to the existing award; and
| | - |  | -------------------------------------------------------------------------------------



| |  |  | provides for accelerated vesting if the participant is terminated without cause or constructively terminated within one year after the change of control.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------

2017 Stock Plan. Under the Willbros Group, Inc. 2017 Stock and Incentive Compensation Plan (the 2017 Stock Plan), no
accelerated vesting, lapsing of restrictions or payment of awards will occur if the Compensation Committee reasonably determines in good faith before the occurrence of a change of control that the award will be honored or assumed, or new rights
substituted for the award by any successor, and the alternative award:



| |  |  | will be based on stock that will be publicly traded in any established U.S. trading market;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | provides the participant with rights and terms that are substantially equivalent or superior to the rights and terms of the existing award;

outstanding awards become fully exercisable and free of all restrictions, and, in the case of performance-based awards, the target payout opportunity shall be deemed to be fully earned, in the event of a change of control of us, as defined in such

Compensation Committee Interlocks and Insider Participation

During 2017, the Compensation Committee was composed of Michael C. Lebens, Phil D. Wedemeyer and Robert L. Sluder (until April 2017), all of
whom are or were independent directors. During 2017, none of our 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 Board of Directors or on
the Compensation Committee.

DIRECTOR COMPENSATION

In setting non-employee director compensation, the Compensation Committee recommends the form and
amount of compensation to the Board of Directors and the Board of Directors makes the final determination. In considering and recommending the compensation of non-employee directors, the Compensation Committee
considers such factors as it deems appropriate, including historical compensation information, level of compensation necessary to attract and retain non-employee directors meeting our desired qualifications
and market data. The Compensation Committee uses Mercer to provide market information on non-employee director compensation, including annual board and committee retainers, board and committee meeting fees,
committee chairman fees, stock-based compensation and total compensation. In addition, Mercer also provides from time to time market information on the number of independent directors, number and types of committees, number of board and committee
meetings, and types of equity vehicles used based on competitive peer group practices. Mercer compares each element of compensation against a peer group of publicly-traded companies using data collected from proxy statement filings and several
industry compensation surveys.

Cash Compensation

Non-employee directors are compensated as follows:



| |  |  | the Chairman of the Board of Directors, if a non-employee director, receives an annual retainer fee of $137,500;
| | - |  | ----------------------------------------------------------------------------------------------------------------



| |  |  | each non-employee director, other than the Chairman of the Board, receives an annual retainer fee of $75,000;
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | each non-employee director receives a fee of $1,500 for each Board meeting attended in person;
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | each non-employee director receives a fee of $750 for each Board meeting attended via telephone conference connection;
| | - |  | ----------------------------------------------------------------------------------------------------------------------



| |  |  | each non-employee director receives a fee of $1,500 for each committee meeting attended on which he serves, with the exception of the Executive Committee for which no fees are
paid;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | each non-employee director receives a fee of $750 for each committee meeting attended on which he serves via telephone conference connection, with the exception of the Executive
Committee for which no fees are paid;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the chair of the Audit Committee of the Board receives an annual retainer fee of $20,000; and

| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------

Employee directors are not paid for their services as directors. We reimburse all directors for out-of-pocket expenses incurred by them in connection with their services as directors.

2017 Stock Plan

The 2017 Stock Plan allows us to grant awards to all employees and to non-employee members of
the Board of Directors. The Compensation Committee utilizes this plan to grant restricted stock awards to non-employee directors.

The awards are subject to transfer restrictions and forfeiture provisions, which generally lapse on the first anniversary of the date of the
award. Awards held by a non-employee director that have not yet vested will generally become fully vested upon the occurrence of the directors death, disability, termination of service as a director at
the end of any full term to which the director is elected or a change in control of us (as defined in this plan).

Director Compensation Table for 2017

The following table summarizes the compensation paid by us to our directors during the year ended December 31, 2017.
Mr. DiPaolo resigned as a director on February 8, 2017. Mr. Gates became a director on February 8, 2017. Mr. Sluder served as a director until his death in April 2017.

CERTAIN
RELATIONSHIPS AND RELATED TRANSACTIONS

Stockholder Agreement

In March 2010, in connection with the acquisition of InfrastruX Group, Inc., we entered into a Stockholder Agreement with InfrastruX
Holdings, LLC (the Investor), which was amended in April 2011 and amended and restated in March 2015 (as amended and restated, the Stockholder Agreement). In February 2017, we and the Investor entered into a Stockholder
Agreement Consent and Waiver (the Consent and Waiver). The Stockholder Agreement (i) establishes certain restrictions on transfer with respect to any shares of our common stock beneficially owned by the Investor and
(ii) provides for certain corporate governance and registration rights. The Audit Committee, with Mr. Lonergan abstaining, has approved the Stockholder Agreement in compliance with the Audit Committee charter provisions for review,
approval or ratification of related person transactions discussed below. The Board of Directors, with Messrs. Lebens and Lonergan abstaining, approved the Consent and Waiver.

Board of Directors. The Stockholder Agreement required that, on the closing date of the acquisition (the Closing Date), we
would increase the size of our Board of Directors from eight to ten members, and that the Board of Directors would appoint Alan B. Levande and Daniel E. Lonergan to fill the newly created vacancies (each, an Investor Designee
and, together with any other directors who may be designated by the Investor, the Investor Designees). Upon the expiration of Mr. Levandes term at the 2011 Annual Meeting, the Board appointed Michael C. Lebens who, along
with Mr. Lonergan, serve as the Investor Designees. The Investor is entitled to designate two Investor Designees as long as the Investor and any affiliate transferees of the Investor (collectively, the Investor Group) beneficially
own all of the shares of our common stock received in connection with the acquisition (the Initial Shares). After such time when the Investor Group no longer beneficially owns all of the Initial Shares, the Investor will have the right
to (i) two Investor Designees, as long as the Investor Group beneficially owns at least 15 percent of all shares of our common stock then outstanding, excluding any issuance of shares on or after April 1, 2011, to any former, current
and future officers, directors and employees of the Company

or its affiliates (Excluded Shares), and (ii) one Investor Designee, as long as the Investor Group beneficially owns at least five percent but less than 15 percent of all
shares of our common stock then outstanding, excluding the Excluded Shares. Based on a Schedule 13D/A filing dated July 14, 2017, the Investor Group ceased to be the beneficial owner of more than five percent of our common stock on
July 12, 2017. However, pursuant to the Consent and Waiver, we waived the provisions of the Stockholder Agreement insofar as they would require the immediate resignation of one or more Investor Designees as a result of the transfer of shares by
the Investor Group.

Any Investor Designees who are designated by the Investor must qualify as independent directors under applicable New
York Stock Exchange listing standards and federal securities laws and regulations, and any categorical standards for independence used by the Board of Directors for determining independence, and be reasonably acceptable to the Nominating/Corporate
Governance Committee of the Board. For as long as the Investor is entitled to designate at least one person to the Board of Directors, the Stockholder Agreement provides that the Company will not increase or decrease the size of the Board without
the approval of each Investor Designee then serving on the Board.

Voting Provisions. The Stockholder Agreement provides that, as
long as the Investor Group beneficially owns at least 10 percent of all shares of our common stock then outstanding, the Investor Group will vote all of its shares of Company common stock in support of the Board of Directors slate of
directors, and be present, in person or by proxy, at all meetings of stockholders of the Company so that all of the shares beneficially owned by the Investor Group may be counted for purposes of determining the presence of a quorum. The Investor has
also agreed that no member of the Investor Group will grant any proxies with respect to the shares of our common stock owned by it, other than to us, our designee or another member of the Investor Group, or deposit any shares of our common stock
into a voting trust or subject any of such shares to any similar arrangement, other than with respect to another member of the Investor Group. Based on a Schedule 13D/A filing dated July 14, 2017, the Investor Group ceased to be the beneficial
owner of more than five percent of our common stock on July 12, 2017.

Standstill Provisions.Pursuant to
the Stockholder Agreement, until the date that is six months after the date on which the Investor is no longer entitled to designate at least one Investor Designee, the Investor has agreed that neither it nor any member of the Investor Group will
directly or indirectly acquire or agree to acquire any shares of our common stock that would result in an increase in the percentage interest held by the Investor Group above the percentage held by the Investor Group on the Closing Date. In
addition, the Investor agreed that neither it nor any member of the Investor Group will take certain actions, including the solicitation of proxies to vote in any election contest with respect to the Company or initiate or induce any other person to
initiate any stockholder proposal.

Transfer Restrictions.Under the Stockholder Agreement, the Investor may freely sell any
of their shares, provided that, without our consent, which consent is not to be unreasonably delayed or withheld, the Investor may not sell, in one transaction or a series of related private transactions, five percent or more of the then-outstanding
shares of our common stock to any one transferee or related group of transferees. Pursuant to the Consent and Waiver, for the period ending June 1, 2019, we consented to the transfer by the Investor of five percent or more of our outstanding
shares to one or more transferees or related group of transferees provided that any such transfers are to one or more affiliates of the Investor or constitute an in-kind distribution of shares to the ultimate
beneficial owners of the Investor or Investor Group. Based on a Schedule 13D/A filing dated July 14, 2017, the Investor Group disposed of an aggregate of 8,083,235 shares of our common stock pursuant to a distribution in kind on July 12,
2017.

Registration Rights.We have agreed to file a registration statement with the SEC which will be available for the
resale of all shares of common stock acquired by the Investor in the acquisition (the Investor Shares). The Investor Group may elect to sell shares under such registration statement in an underwritten public offering. In addition, the
Stockholder Agreement provides the Investor Group with certain piggyback registration rights, pursuant to which the Investor Group may elect to participate in an underwritten public offering of our common stock initiated by us or another
Willbros stockholder.

Transactions with KKR Credit Advisors (US) LLC and Affiliates

On March 31, 2015, we entered into the First Amendment to the Credit Agreement (the First Amendment), by and among us, as
borrower, certain subsidiary guarantors party thereto, the lenders party thereto (the Lenders), KKR Credit Advisors (US) LLC (KKR Credit US), as arranger, and JPMorgan Chase Bank, N.A., as administrative agent, which amends
our term credit agreement dated as of December 15, 2014 (the Term Credit Agreement). On September 28, 2015, March 1, 2016, July 26, 2016, March 3, 2017, November 6, 2017 and March 27, 2018, we further
amended the Term Credit Agreement (together with the First Amendment, the Term Credit Agreement Amendments). The Term Credit Agreement Amendments, among other things, suspend compliance with certain covenants for the calculation periods
ending December 31, 2014 through December 31, 2017 (the Covenant Suspension Period) and provides that any failure by the Company to comply with such financial covenants during the Covenant Suspension Period will not be deemed
to result in a default or event of default under the Term Credit Agreement. We paid $2.3 million in amendment fees during the year ended December 31, 2017. The Board of Directors, including all members of the Audit Committee, approved the
Term Credit Agreement Amendments.

Term Forbearance Agreement. On March 27, 2018, we entered into a Forbearance Agreement (the
Term Forbearance Agreement), by and between us, as borrower, the other loan parties party thereto and the lenders party thereto (the Forbearing Lenders). Pursuant to the Term Forbearance Agreement, each of the borrowers and
guarantors acknowledged that certain defaults and events of default (Term Specified Defaults), have occurred and are continuing or will occur under the Term Credit Agreement, and the Forbearing Lenders have agreed to forbear from
exercising their rights and remedies under the Term Credit Agreement and other loan documents that arise solely as a result of the Term Specified Defaults for a limited period expiring on the earlier of August 15, 2018 or the occurrence of any
one of several specified termination events. The Board of Directors, including all members of the Audit Committee, approved the Term Forbearance Agreement.

Subscription Agreement.In consideration for the covenant relief described above and the other terms and provisions of the First
Amendment, on March 31, 2015, we entered into a Subscription Agreement (the Subscription Agreement) for the issuance of 10,125,410 shares (the Common Shares) of our common stock to the subscribers listed therein (the
Subscribers), in a private placement. The Common Shares were issued on March 31, 2015, contemporaneously with the execution of the Subscription Agreement. As a result of this transaction, the Subscribers are now considered
related persons within the meaning of the SECs rules and regulations.

Board of Directors Observer and Representation
Right. Pursuant to the First Amendment, the Lenders holding more than 50 percent of the sum of the aggregate principal amount of the loans outstanding under the Term Credit Agreement (the Majority Lenders) may designate one
representative (an Observer) reasonably acceptable to the Nominating/Corporate Governance Committee of our Board of Directors to attend and observe (but not vote) at all meetings of the Board of Directors and any committee thereof.
Additionally, upon prior written notice from the Majority Lenders to the Company and the Board of Directors, we are required to take all appropriate action under our organizational documents to expand the Board of Directors by one board seat (unless
there is an existing vacancy on the Board of Directors), and to fill such new seat or existing vacancy with a designee nominated by the Majority Lenders who is reasonably acceptable to the Nominating/Corporate Governance Committee of the Board (the
Lender Designee). If the Majority Lenders designate a Lender Designee, the Majority Lenders right to designate an Observer ceases while any such Lender Designee is serving as a member of the Board of Directors. If KKR Credit US and
its affiliates cease to hold at least five percent of the outstanding shares or our common stock, Majority Lenders rights to designate an Observer or Lender Designee will terminate. The Majority Lenders have exercised their right to designate
an Observer.

Registration Rights.In connection with the private placement of the Common Shares described above, on March 31,
2015, we entered into a Registration Rights Agreement (the Registration Rights Agreement) with the Subscribers and KKR Credit US, as the representative of the Subscribers thereunder. If at any time we propose to register shares of common
stock in connection with a public offering of common stock, we are required to use our reasonable best efforts to cause to be registered on the related registration statement all of the Common Shares that any Subscriber or permitted transferee
requests to be included in such public offering (commonly referred to as piggyback registration rights). Additionally, the Registration Rights Agreement gives KKR Credit US demand registration rights, pursuant to which KKR
Credit US may request that the Company file a registration statement to

##### Table of Contents

register the Common Shares then owned by the Subscribers (or their permitted transferees). KKR Credit US may request up to a total of four demand registrations and the value of Common Shares that
may be offered for sale by the Subscribers (or their permitted transferees) in connection with any registered demand offering must be at least $5 million.

Review, Approval or Ratification of Transactions with Related Persons

Our Audit Committee Charter provides that our Audit Committee shall review and approve or ratify any transaction between us and a related
person, which is required to be disclosed under the rules of the Securities and Exchange Commission. For purposes of this requirement, the terms transaction and related person have the meanings contained in Item 404 of
Regulation S-K. In the course of its review and approval or ratification of a transaction, the Audit Committee will consider:



| |  |  | the nature of the related persons interest in the transaction;
| | - |  | ---------------------------------------------------------------



| |  |  | the material terms of the transaction;
| | - |  | --------------------------------------



| |  |  | the significance of the transaction to the related person;
| | - |  | ----------------------------------------------------------



| |  |  | the significance of the transaction to us;
| | - |  | ------------------------------------------



| |  |  | whether the transaction would impair the judgment of a director or executive officer to act in our best interest; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | any other matters the Audit Committee deems appropriate.
| | - |  | --------------------------------------------------------

Any Audit Committee member who is a related person
with respect to a transaction under review may not participate in the deliberations or vote respecting such approval or ratification; provided, however, that such member may be counted in determining the presence of a quorum at a meeting of the
Audit Committee which considers the transaction.

DIRECTOR INDEPENDENCE

The Board of Directors has affirmatively determined that each of Messrs. Gates, Lebens, Lonergan, Wedemeyer and Williams, current
directors of the Company, are independent under the current director independence standards of the New York Stock Exchange. Mr. DiPaolo, who served as a director until his resignation on February 8, 2017, was also independent.
Mr. Sluder, who served as a director until his death in April 2017, was also independent. In reaching its conclusion, 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 us (either directly or as a partner, stockholder or officer of an organization that has a relationship with us). 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 considered the standard that no relationships exist between Messrs. Gates, Lebens, Wedemeyer, Williams, DiPaolo and Sluder, on the one
hand, and the Company on the other, that are required to be reported under the caption Certain Relationships and Related Transactions in this Item 13 pursuant to the rules and regulations of the SEC. These standards are set forth as an
exhibit every year to our proxy statement for our annual meeting of stockholders, which is available on our website at http://www.willbros.com. In reviewing the independence of Mr. Lonergan, the Board of Directors also took into account
the existence of the Stockholder Agreement, including the consent and waiver, discussed above under the caption Certain Relationships and Related Transactions  Stockholder Agreement under this Item 13 and concluded that this
relationship does not and will not impair the judgment of Mr. Lonergan to act in the best interests of Willbros.

Mr. Fournier
is not considered to be independent because of his concurrent employment as our President and Chief Executive Officer.
