EMPLOYMENT AGREEMENT

THIS EMPLOYMENT AGREEMENT (this “Agreement”) is made and entered into as of the 20th day of
September, 2010, between Willbros United States Holdings, Inc. (f/k/a Willbros USA, Inc.), a
Delaware corporation (the “Corporation”), and Robert R. Harl (the “Executive”).

RECITALS

WHEREAS, the Executive and the Corporation entered into the Amended and Restated Employment
Agreement with the Executive dated December 31, 2008, which contract will expire by its own terms
on December 31, 2010;

WHEREAS, the Board of Directors of Willbros Group, Inc., the parent company of the
Corporation, believes it would be in the best interest of WGI and the Affiliates (as defined below)
for the Executive to continue to serve as President and Chief Executive Officer of the Corporation
and WGI; and

WHEREAS, the Executive and the Corporation have agreed to a new contract as set forth herein;

NOW, THEREFORE, in consideration of the mutual covenants and representations contained herein,
and the mutual benefits derived from this Agreement, the Corporation and the Executive agree as
follows:

ARTICLE I

DEFINITIONS

The following words, if the first letter of such words is capitalized, shall have the meanings
set forth below:

“2008 Employment Agreement” shall refer to the Amended and Restated Employment Agreement dated
December 31, 2008, entered into by the Executive and the Corporation and shall include the
Employment Agreement entered into on January 26, 2006, by the Executive and the Corporation, as
amended on January 16, 2006, and January 15, 2008.

“Affiliate” means any entity (including corporations, limited liability partnerships, and
limited liability companies) that, either directly or indirectly, is under common ownership with
the Corporation or WGI, provided that common ownership shall not be based on ownership in an entity
of less than fifty-one (51%) percent.

 

1

 

“Base Amount” means the Executive’s “annualized includible compensation for the base period,”
as defined in section 280G of the
Code (including sections 280G (b)(3) and (d)(1)) and the regulations related to section 280G,
including those found at 26 CFR part 1 (including Treas. Reg., section 1.280G-1, Q-34, A-34, Q-35
and A-35).

“Base Salary” shall have the meaning set forth in Section 4.1 below.

“Board” shall refer to the Board of Directors of WGI.

“Business Day” shall mean any day that is not a Saturday, Sunday, or Federal Holiday.

“Cause,” as a grounds for Termination of the Executive’s employment prior to the end of the
Employment Period, means (i) conduct by the Executive that is so unacceptable or offensive that, by
its nature, it renders the Executive incapable of performing his duties hereunder, including
substantial non-performance of his job responsibilities after the Executive has been provided
written notice of such nonperformance and a reasonable time period, not to exceed six months, has
passed without substantial correction of such nonperformance; (ii) the Executive engaging in
conduct so reprehensible that a reasonable person would view the same as compromising the moral
and/or ethical principles of the Corporation or WGI; (iii) the Executive being convicted of
embezzlement, fraud, perjury, alteration of documents, robbery, or any other felonious act; (iv)
the Executive’s breach of his obligations, as set forth in this Agreement, with regard to
non-competition, non-solicitation of employees of the Corporation, WGI or an Affiliate to work for
outside companies, or non-disclosure of Confidential Information; (v) willful failure by the
Executive to substantially perform his duties, which results in a significantly adverse effect upon
the Corporation, WGI or an Affiliate, after the Executive has been provided written notice, in
reasonable detail, of such failure and a 30-day time period after such notice within which to cure
such failure; (vi) gross negligence or willful misconduct of the Executive which results in a
significantly adverse effect upon the Corporation, WGI or an Affiliate; or (vii) willful violation
or disregard by the Executive of any published policy of the Corporation, WGI or an Affiliate that
results in a significantly adverse effect upon the Corporation, WGI or an Affiliate. No act or
failure to act on the Executive’s part shall be considered “willful” unless done or omitted to be
done by the Executive not in good faith and without reasonable belief that such act or omission was
in the best interest of the Corporation, WGI or an Affiliate.

“Change in Control” means and shall be deemed to have occurred if:

	 	(i)	 	any Person, other than WGI or a Related Party, becomes the
“beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly
or indirectly, of securities of WGI representing 51 percent or more of the
total voting power of all the then-outstanding Voting Securities;

	 	(ii)	 	any Person, other than WGI or a Related Party, purchases or
otherwise acquires under a tender offer, securities representing 51 percent or
more of the total voting power of all the then-outstanding Voting Securities;

 

2

 

	 	(iii)	 	the stockholders of WGI approve a merger, consolidation,
recapitalization or reorganization of WGI or an acquisition by WGI, or any
such transaction is consummated if stockholder approval is not obtained;
provided that no Change in Control shall have occurred if any such merger,
consolidation, recapitalization, reorganization, acquisition or transaction
would result in the Voting Securities outstanding immediately prior thereto
continuing to represent, either by remaining outstanding or by being converted
into voting securities of the surviving entity (or if the surviving entity is
a subsidiary of another entity, then of the parent entity of such surviving
entity), at least 60 percent of the total voting power represented by the
voting securities of the surviving entity (or parent entity) outstanding
immediately after such transaction and in which, or as a result of which, the
voting rights of each Voting Security relative to the voting rights of all
other Voting Securities are not materially altered;

	 	(iv)	 	the stockholders approve a plan of complete liquidation of
WGI or an agreement for the sale or disposition by WGI of all or substantially
all of WGI’s assets, other than any such transaction which would result in a
Related Party owning or acquiring more than 50 percent of the assets owned by
WGI immediately prior to the transaction; or

	 	(v)	 	the Board or an appropriate committee thereof adopts a
resolution that a Change in Control has occurred, provided that no inside
director votes on such resolution.

No event shall constitute a Change in Control under this Agreement unless such event, transaction,
or series of events or transactions also constitutes a “change in the ownership or effective
control of the company, or in the ownership of a substantial portion of the assets of the company,”
as such terms are defined in Treasury Regulations prescribed under Section 409A. Any event,
transaction, or series of events or transactions that would constitute a Change in Control under
this definition and that relates to, results from or constitutes a part of the insolvency of, or a
bankruptcy, bankruptcy reorganization, or receivership of the Corporation or WGI, shall not
constitute a Change in Control or otherwise operate to trigger the obligation to pay amounts
otherwise payable upon the early termination of this Agreement. Upon the occurrence of a Change in
Control, no subsequent event or condition caused by the earlier Change in Control shall constitute
a Change in Control for purposes of this Agreement.

“Change-in-Control-Related-Termination” means, subject to the exceptions immediately following
the two bullet points below:

	 	•	 	The Executive’s Involuntary Separation from Service: (a) by Termination In
Anticipation of a Change in Control or (b) within three years following a Change in
Control; and

	 	•	 	Any Termination of the Executive’s employment with the Corporation as a result
of the Executive’s resignation for Good Reason: (a) In Anticipation of a Change in
Control or (b) within 18 months following a Change in Control.

 

3

 

For purposes of this Agreement, the following would not constitute any element of a
Change-in-Control-Related-Termination:

	 	(i)	 	a Termination resulting from the Executive’s death or Disability;

	 
	 	(ii)	 	a Termination for Cause;

	 	(iii)	 	a Termination resulting from the Executive’s voluntary
resignation that is not due to Good Reason;

	 	(iv)	 	any Termination that does not constitute an Involuntary
Separation from Service;

	 	(v)	 	the expiration of this Agreement by its own terms and/or the
Corporation’s failure to extend or renew this Agreement;

	 	(vi)	 	the Corporation’s hiring a new President and/or Chief Executive
Officer following the expiration of this Agreement;

	 	(vii)	 	the Executive’s resignation, for any reason, following the
expiration of this Agreement; or

	 	(viii)	 	in the event that the Executive remains employed by the Corporation following
expiration of the Employment Period, any changes in Executive’s titles, duties,
responsibilities, compensation, or other terms or conditions of employment that
take effect after the Employment Period.

Notwithstanding any other provision of this definition of “Change-in-Control-Related-Termination,”
if the event that constitutes a Change in Control occurs during the Employment Period and,
following the expiration of this Agreement, the Executive remains employed with the Corporation
without a new employment contract being signed, no Termination of the
Executive’s employment (whether voluntary or involuntary) that occurs more than a year after the
expiration of the Employment Period shall constitute a Change-in-Control-Related-Termination. No
Change in Control that occurs after the expiration of the Employment Period can serve as the basis
for a Change-in-Control-Related-Termination, unless it is a Change in Control that occurs within
three months after the expiration of the Employment Period and is part of a set of circumstances
that meet the definition of a Termination In Anticipation of a Change in Control.

 

4

 

“COBRA” shall mean continuation coverage pursuant to Part 6 of Title I of ERISA.

“Code” means the Internal Revenue Code of 1986, as amended.

“Committee” shall mean the Compensation Committee of the Board.

“Confidential Information” means any information not already lawfully available to the public
concerning the Corporation, WGI or any Affiliate. Confidential Information, includes computer
programs written for or customized for the Corporation or an Affiliate’s products; product
development; business strategy; financial information; information compiled by the Corporation or
an Affiliate about upcoming client projects and opportunities to provide additional services to
clients; and client, supplier or employee lists. Confidential Information also includes any
technical data, design, pattern, formula, source code, object code, algorithm, manual, product
specification, or plan for a new, revised or existing product or service; any business, marketing
or financial plan; any sales order; and information pertaining to the present or future business or
products of the Corporation or an Affiliate. Confidential Information also includes information
belonging to the clients or vendors of the Corporation or an Affiliate that the Corporation or an
Affiliate has agreed to hold in confidence. All Trade Secrets are also Confidential Information.
However, public information, even if it falls within a category set forth in this definition, is
not Confidential Information.

“Compensation Committee” shall refer to the Compensation Committee of the Board.

“Disability” means a physical or mental condition (or conditions) that causes, or is
reasonably expected to cause, the Executive to be unable to perform substantially all of the duties
of his position hereunder for a period of six months or more in any 12-month period as determined
by a physician selected jointly by the Executive and the Board, provided that Disability shall not
result in any payments to the Executive under Section 7.4 hereof (or of any acceleration of vesting
or payments or payment of any post-Termination benefits) unless and until such Disability results
in a Separation from Service.

“Effective Date” means January 1, 2011, the date on which this Agreement becomes effective.
This Agreement will never become effective if, for any reason, Executive is not employed by the
Corporation as its Chief Executive Officer on December 31, 2010.

“Employment Period” means the period from the Effective Date through January 1, 2014.

“ERISA” means the United States Employee Retirement Income Security Act of 1974, as amended.

“Exchange Act” means the United States Securities Exchange Act of 1934, as amended.

 

5

 

“Good Reason” means the occurrence of any of the following events, unless the Executive has
consented thereto:

	 	(i)	 	a material diminution in the Executive’s Base Salary, except that a reduction
in the Executive’s Base Salary is not Good Reason if it is made as part of an
across-the-board salary reduction that affects all of the Corporation’s senior
management team;

	 	(ii)	 	a change in the location of the Executive’s principal place of employment by 50
miles or more from the location at which the Executive must perform the services;

	 	(iii)	 	a change in the Executive’s reporting relationship so that he reports to a
corporate officer or employee instead of reporting directly to the Board; or

	 
	 	(iv)	 	a material diminution in the Executive’s authority, duties or responsibilities.

An event does not constitute Good Reason unless the Executive provides the Corporation with written
notice of the existence of the condition that constitutes the Good Reason. Such notice must be
provided within 90 days after the initial existence of such condition, and the notice must provide
the Corporation with at least 30 days during which it may remedy such condition without being
required to make any Termination-related payment to the Executive. For purposes of this Agreement,
the Executive’s voluntary Separation from Service for Good Reason will be treated as an Involuntary
Separation from Service.

“In Anticipation of a Change in Control” means an event occurring after the Effective Date and
within the three-month period ending on the date of a Change in Control.

“Involuntary Separation from Service” means the Executive’s Separation from Service due to the
independent exercise of unilateral authority of the Corporation as the Executive’s employer. A
Separation from Service that occurs at the Executive’s request is not an Involuntary Separation
from Service unless the
Executive resigns for Good Reason. A Separation from Service is an Involuntary Separation from
Service only if the Executive is able and willing to continue performance of services for the
Corporation at the time of such separation.

“Person” shall have the meaning assigned in the Exchange Act.

“Related Party” means (i) an Affiliate, (ii) an employee or group of employees of the
Corporation or an Affiliate, (iii) a trustee or other fiduciary holding securities in WGI under an
employee benefit plan of the Corporation or an Affiliate, or (iv) a corporation or other business
entity owned directly or indirectly by the stockholders of WGI in substantially the same proportion
as their ownership of stock of WGI.

 

6

 

“Release” shall mean the Separation Agreement and Release attached to this Agreement as
Exhibit 4. If the Executive’s employment is Terminated under circumstances that may trigger
payments contingent on the Executive’s signing of the Release, the Corporation shall deliver to the
Executive a finalized version of the Release no later than the seventh day following his Separation
from Service. No payment shall be made on the Release unless the Executive signs it and returns it
to the Corporation (using the notice procedures set forth in Article XII below) within 21 days
following his receipt from the Corporation of a finalized version of the Release (or within 45 days
after his receipt from the Corporation of a finalized version of the Release if he is Terminated as
part of a termination program offered to a group or class of employees within the meaning of 29 USC
section 626(f)(1)(F)(ii) of the Age Discrimination in Employment Act). Any reference in this
Agreement to a “timely” return of the Release shall refer to a return of a properly executed
Release to the Corporation within the 21-day time period described in this definition of “Release,”
or, if the 45-day time period applies, within the 45-day time period described in this definition
of “Release.” If no payment date is otherwise specified herein, any payment in this Agreement
that is contingent on the Executive’s timely execution and return of the Release shall be made on
the 10th Business Day following the expiration of the seven-day revocation period described in 29
USC section 626(f)(1)(G) of the Age Discrimination in Employment Act. 

“Section 409A” shall mean Section 409A of the Code and the applicable regulations issued
thereunder.

“Separation from Service” shall mean a change in the Executive’s relationship with the
Corporation and WGI that meets the following conditions: (i) constitutes the voluntary or
involuntary severing of the Executive’s employment with the Corporation and WGI (and all entities
which would be included with the Corporation and/or WGI as the “service recipient” under the
definition of such term in the Treasury Regulations pertaining to Section 409A) for any reason,
including resignation by the Executive and Termination of the Executive on account of retirement,
death, or disability, and (ii) results in a permanent decrease in the level of bona fide services
performed by the Executive for the Corporation and/or WGI and other service recipients (as defined
above) to a
level that is not more than 20 percent of the level of services performed by the Executive for the
Corporation and/or WGI (and other service recipients, as defined above) over the immediately
preceding 36-month period. A Separation from Service shall not include a leave of absence, paid or
unpaid, under which there is a reasonable expectation that the Executive will return to perform
services for the Corporation, WGI and/or other service recipients, as defined above, if the period
of such leave does not exceed six months. A Separation from Service shall not include a cessation
of services for a period during which the Executive retains a right to reemployment, either by
statute or contract.

“Severance Compensation” means the sum of the following:

	 	(i)	 	the highest annual Base Salary that the Corporation (and WGI or any Affiliate)
has paid to the Executive at any time during the 36 months preceding his Separation
from Service; and

	 	(ii)	 	the Executive’s greatest annual cash bonus received from the Corporation, WGI
and any Affiliate under Section 4.2 of this Agreement during the 36-month period ending
on the date of the Change in Control (or, if such Separation from Service occurs prior
to the date of a Change in Control, then ending on the date of such Separation from
Service).

 

7

 

“Severance Plan” means the Willbros Group, Inc. Severance Plan, as amended and restated
effective September 25, 2003, and as amended by Amendment No. 1 dated December 31, 2008.

“Short-Term Deferral Period” means that period ending on the later of the
15th day of the third month following the end of the Executive’s tax year in which the
Executive’s Separation from Service occurs or the 15th day of the third month following
the end of the Corporation’s tax year in which the Executive’s Separation from Service occurs.

“Termination” means, when referring to the Executive’s cessation of employment with the
Corporation, WGI or an Affiliate, the Executive’s Separation from Service. “Terminate” and
“Terminated” shall have correlative meanings.

“Termination in Anticipation of a Change in Control” means either of the following events if
they occur after the Effective Date and within a three-month period ending on the date of a Change
in Control: (a) the Executive’s Involuntary Separation from Service without Cause, or (b) the
Executive’s resignation for Good Reason. An Involuntary Separation from Service without Cause that
subsequently becomes a Termination in Anticipation of a Change in Control shall not entitle
Executive to any payments and benefits under this Agreement that exceed those he would have
received if the Change in Control had occurred on the day before his Involuntary Separation from
Service without Cause.

“Trade Secrets” means all or any part of any of the following property of the Corporation,
WGI, or any Affiliate: business plans, product plans, policies and procedures (including computer
procedures), lists of clients or prospective clients and related information about clients and
prospective clients, sales and marketing plans, financial data, designs, processes, procedures,
formulae, compilations of information, improvements, or inventions that: (i) are known to the
Corporation, WGI or an Affiliate, (ii) are considered confidential by the Corporation, WGI or an
Affiliate, and (iii) give the Corporation, WGI or an Affiliate an advantage over competitors that
do not know or use it.

election of directors.

ARTICLE II

TERMINATION OF PRIOR CONTRACT AND SEVERANCE PLAN

2.1 EXPIRATION OF 2008 EMPLOYMENT AGREEMENT. The parties acknowledge that the 2008
Employment Agreement will expire by its own terms on December 31, 2010. The Corporation and the
Executive agree that such expiration shall not entitle the Executive to: (a) any payments or other
benefits under Section 4.3 of the 2008 Employment Agreement or under any other section of the 2008
Employment Agreement; (b) any of the payments or other benefits described in the Severance Plan; or
(c) any other Termination-related or Change in Control payments or benefits whatsoever.

2.2 TERMINATION OF SEVERANCE PLAN. The Executive hereby irrevocably consents to the
termination, effective immediately, of the Severance Plan with respect to the Executive and his
rights thereunder and waives and forever renounces any right that he now has or might ever have to
receive any payment or benefit of any kind under the Severance Plan or any predecessor to (or
previous or subsequent version of) the Severance Plan. The Executive agrees never to seek any
payment or benefit under the Severance Plan and never to accept such payment or benefit if it is
offered. The Executive agrees to sign any document that the Corporation reasonably requests
that he sign in the future with regard to termination of the Severance Plan and/or termination of
the Executive’s rights under the Severance Plan. To the extent that this Agreement should be
construed as an amendment to the Severance Plan rather than a termination of the Severance Plan,
the Executive, in accordance with Section 6.2 of the Severance Plan, hereby expressly consents to
the amendment of the Severance Plan as set forth in this Agreement and hereby waives each and every
benefit and right described in the Severance Plan, except to the extent that such benefit or right
is also expressly set forth in this Agreement. To the extent that the Severance Plan, or any part
thereof, were construed as surviving as to the Executive despite the provisions of this Agreement,
then, as to the Executive, this Agreement hereby supersedes the Severance Plan.

2.3 STOCK PLANS. In the event of any conflict between this Agreement and the WGI 1996
Stock Plan or the WGI 2010 Stock Plan, as applied to the Executive, this Agreement shall control.

ARTICLE III

DUTIES OF EXECUTIVE

3.1 POSITION.

(a) The Corporation hereby engages the Executive as a full-time executive employee for the
period specified in Section 6.1 below, and the Executive accepts such employment, on the terms and
conditions set forth in this Agreement.

(b) The Executive shall serve as the President and Chief Executive Officer of the Corporation
and WGI. He shall report to the Board, but to no other person or body.

 

9

 

3.2 DUTIES.

(a) In addition to the Executive’s performance of his day-to-day executive and operating
responsibilities as President and Chief Executive Officer, the Executive shall work diligently and
closely with the Board during the Employment Period to further develop, refine, and implement the
Corporation’s strategic plan consistent with the annual budget(s) and other objectives approved by
the Board.

(b) Throughout the Employment Period, the Executive shall devote substantially all his full
time and efforts to the business of the Corporation and WGI and will not engage in consulting work
or any trade or business for his own account or for or on behalf of any other person, firm or
corporation that competes, conflicts or interferes with the performance of his duties under this
Agreement in any way.

(c) Except for reasonable business travel, the Executive shall be required to perform the
services and duties provided for in this Section 3.2 only at the principal offices of the
Corporation in the Houston, Texas,
metropolitan area. Throughout the Employment Period, the Executive shall be entitled to vacation
and leave for illness or temporary disability in accordance with the Corporation’s policies for its
senior executive officers.

ARTICLE IV

COMPENSATION

4.1 BASE SALARY. In consideration of the Executive foregoing other business
opportunities and agreeing with the Corporation and WGI to perform the services described in this
Agreement, during the Employment Period, the Corporation shall pay the Executive a base salary of
$900,000.00 per year (the “Base Salary”). The Base Salary shall be payable in periodic equal
installments, no less frequently than monthly, pursuant to the Corporation’s executive payroll
system. During 2010, the Corporation attempted to increase the Executive’s annual base salary from
$700,000 to $900,000, but the Executive declined to accept the salary increase. In the event that,
as of the Effective Date, the Executive still has not agreed to accept $900,000 as his annual
salary, the Executive shall have the right, on 30 days’ notice, to cause the Corporation to
increase his salary to $900,000 per year, but no such change shall be retroactive.

4.2 CASH BONUS. The Executive shall be entitled to an annual cash bonus for each
calendar year of his employment with the Corporation during the Employment Period if the
performance goals described on Exhibit 1 to this Agreement are achieved. The Board in its
discretion, and following consultation with the Executive, may annually modify the performance
goals set forth in Exhibit 1, with any such modified version of Exhibit 1 to be provided to the
Executive within 30 days following the start of the new calendar year. The performance period will
be the entire calendar year. Any cash bonus earned by the Executive for any year shall be payable
no later than March 15 of the year following the year with respect to which the bonus is payable.
The material terms of the performance goals described in Exhibit 1 have been incorporated into a
management incentive plan for WGI and the Affiliates and approved by the Compensation Committee and
the Board. Any cash bonus paid under this Section 4.2 shall be subject to Exhibit 1 and to the
management incentive plan. The Executive’s target annual cash bonus payable under this Section 4.2
shall be the amount of his Base Salary. The Executive’s maximum annual cash bonus payable under
this Section 4.2 shall be 150 percent of his Base Salary.

4.3 LONG-TERM INCENTIVE AWARDS. The Board may grant the Executive a long-term
incentive (“LTI”) award for each of the three calendar years covered by this Agreement, based on
achievement of the performance goals described in Exhibit 2 hereto. In each case, the performance
period will be the entire calendar year. The Board in its discretion, and following consultation
with the Executive, may annually modify the performance goals set forth in Exhibit 2, with any such
modified version of Exhibit 2 to be provided to the Executive within 30 days following the start of
the new calendar year. The performance goals described in Exhibit 2 to this Agreement have been
incorporated into the WGI 2010 Stock Plan, and the WGI 2010 Stock Plan has been approved by the
Compensation Committee, the Board and the stockholders of WGI. Any LTI awards made under this
Section 4.3 shall be subject to Exhibit 2 hereto and to the WGI 2010 Stock Plan. Any LTI award that
the Executive receives under this Section 4.3 may be made in any form allowed by the WGI 2010 Stock
Plan; provided, that any LTI award made to the Executive under this Agreement that vests following
January 1, 2014 (the date of
expiration of this Agreement), shall be made in cash or in Restricted Stock Units. The Executive’s
target annual long-term incentive award under this Section 4.3 shall be $4 million and his maximum
annual long-term incentive award shall be $8 million. The Board, based on achievement during a
calendar year within the Employment Period of the performance goals set forth in Exhibit 2 and/or
the WGI 2010 Stock Plan, shall determine the amount of the annual LTI Award that the Executive has
earned. At the end of a calendar year and based on the extent of achievement of such performance
goals, the Board shall have discretion to determine the amount (from zero to the target of $4
million or, for maximum achievement of performance goals, up to the maximum of $8 million) of the
annual LTI award earned by the Executive during that particular calendar year. Any such decision
by the Board shall be made no later than March 10 following the calendar year on which the subject
LTI award was based. Should the Executive not earn all or part of the annual LTI award that he
could have earned for a particular calendar year, the unearned part shall be forever forfeited and
shall never vest. The annual LTI awards described in this Section 4.3, to the extent earned, shall
vest as follows:

2011 Annual LTI Award

1/3 of any earned amount vests on March 15, 2012

1/3 of any earned amount vests on March 15, 2013

1/3 of any earned amount vests on March 15, 2014

2012 Annual LTI Award

1/3 of any earned amount vests on March 15, 2013

1/3 of any earned amount vests on March 15, 2014

1/3 of any earned amount vests on March 15, 2015

2013 Annual LTI Award

1/3 of any earned amount vests on March 15, 2014

1/3 of any earned amount vests on March 15, 2015

1/3 of any earned amount vests on March 15, 2016

 

11

 

To the extent that an annual LTI award is paid partly or wholly in cash, any cash payment
earned shall be paid to the Executive on March 15 of the calendar year in which the award vests (or
if March 15 falls on a Saturday or Sunday, then on the last day prior to March 15 that is not a
Saturday). If, prior to January 1, 2014, the Executive voluntarily resigns from the Corporation
(other than based on Good Reason), or if his employment is Terminated for Cause, any unvested LTI
award shall be forfeited. After January 1, 2014 (the expiration date of this Agreement), the
Executive’s voluntary resignation from the Corporation shall not prevent the Executive from
receiving, on the scheduled vesting date, any LTI award that was not previously forfeited. A
proforma illustrating the application of the LTI awards that may be granted under this Section 4.3
is attached as Exhibit 3.

As to any award granted or earned under this Section 4.3, the Compensation Committee, in its
sole discretion, may determine what percent of the award shall be in cash and what percent shall be
in the form of equity in WGI
or in an equity-based form based on WGI stock, and, if the method of payment is equity in WGI or an
equity-based form, whether such payment shall be made by restricted stock, unrestricted stock,
stock options, stock appreciation rights, or some other form of equity in WGI. No later than March
12 of 2012, 2013 and 2014, the Board shall provide the Executive with a letter specifying the
percentage of stock (and type of stock grant and the percentage of each type of stock grant
included in the award, if more than one type is included) and the percentage of cash in any LTI
award that he earned based on the previous year.

4.4 SHAREHOLDER APPROVAL. The material terms of the management incentive plan
referenced in Section 4.2 above and the WGI 2010 Stock Plan were submitted to and approved by the
stockholders of WGI on May 26, 2010. As provided in Treas. Reg. section 1.162-27(e)(5), prior to
payment of any cash bonus described in Section 4.2 above or payment or award of any LTI described
in Section 4.3 above, the Compensation Committee must certify in writing that the performance goals
and any other material terms were in fact satisfied.

ARTICLE V

COMPETITION AND CONFIDENTIAL INFORMATION

5.1 COMPETITION AND CONFIDENTIAL INFORMATION. The Corporation hereby agrees, during
the period in which the Executive is employed under this Agreement, to provide the Executive with
continued access to the Trade Secrets and the Confidential Information, including its present and
prospective business plans, detailed financial data, financing arrangements, marketing projections,
customer lists, contracts between the Corporation and its customers, and bid proposals submitted by
the Corporation to its customers. The Executive acknowledges that the Trade Secrets and the
Confidential Information are updated on a continuous basis. Furthermore, the Executive and the
Corporation recognize that, due to the nature of his association with the Corporation and WGI and
of his engagements hereunder, and the relationship of the Executive to the Corporation and WGI, as
an executive in the future hereunder, the Executive will have access to and will acquire, and has
assisted in and will assist in developing, confidential and proprietary information relating to the
business and operations of the Corporation, WGI and the Affiliates, including information with
respect to present and prospective business plans, financing arrangements, marketing projections,
customer lists, contracts and proposals. The Executive acknowledges that such information has been
and will continue to be of central importance to the business of the Corporation, WGI, and the
Affiliates and that disclosure or use by others could cause substantial loss to the Corporation,
WGI and the Affiliates. The Executive will treat as confidential any Confidential Information,
Trade Secrets, or proprietary information of the Corporation, WGI and the Affiliates that are now
known to him or that hereafter may become known to him as a result of his employment or association
with the Corporation, WGI or the Affiliates, and shall not at any time directly or indirectly
disclose any such information to any person, firm or
corporation, or use the same in any way other than in connection with the business of the
Corporation, WGI and the Affiliates.

 

12

 

5.2 NON-COMPETITION. The Executive and the Corporation recognize that an important
part of the Executive’s duties will be to develop goodwill for the Corporation, WGI and the
Affiliates through his personal contact with vendors, customers, subcontractors, and others sharing
business relationships with the Corporation, WGI, and the Affiliates, and that there is a danger
that this goodwill, a proprietary asset of the Corporation, WGI and the Affiliates, may follow the
Executive if and when his employment relationship with the Corporation is terminated. For that
reason, and also in support of his obligation to protect the confidentiality of the Trade Secrets,
Confidential Information and proprietary information of the Corporation, the Executive agrees that,
during the Employment Period and for a period of one year following his Separation from Service,
the Executive will not, either individually or as owner, partner, agent, employee, or consultant,
directly or indirectly:

(a) engage in any activity competitive with the upstream or downstream oil and gas or
electrical transmission and distribution engineering or construction businesses of the Corporation,
WGI or any of the Affiliates or with any other lines of material business activity of the
Corporation, WGI or any of the Affiliates that commence during the Employment Period; or

(b) solicit any employee to leave the employment of the Corporation, WGI or any of the
Affiliates; or

(c) hire or retain the services of, or assist any other person or entity in hiring or
retaining the services of, any person who has been employed by the Corporation, WGI or any of the
Affiliates at any time during the 12 months prior to such hiring or retaining, provided that this
clause (c) shall not apply to an ex-employee who was involuntarily terminated by the Corporation,
WGI or the Affiliates more than six months prior to the time that the Executive hires or retains,
or seeks to hire or retain, such ex-employee, or to any ex-employee of the Corporation, WGI or the
Affiliates whom WGI’s Chairman of the Board or the Corporation’s or WGI’s next Chief Executive
Officer gives the Executive written consent to hire or, retain, or seek to hire or retain.

 

13

 

Nothing in this Article V shall be construed to prevent the Executive from owning, as an
investment, not more than one percent of a class of equity securities issued by any issuer and
publicly traded and registered under Section 12 of the Exchange Act.

5.3 CORPORATION’S REMEDIES FOR BREACH. It is recognized that damages in the event of
a breach of Sections 5.1 and/or 5.2 of this Agreement by the Executive would be difficult, if not
impossible, to ascertain, and it is therefore agreed that, if such a breach occurs, the
Corporation, in addition to and without limiting any other remedy or right it may have, may have
the right to an injunction or other equitable relief, in any court of competent jurisdiction,
enjoining any such breach. Furthermore, in the event of a material breach by the Executive of
Section 5.2 above,
the Corporation, upon 10 days’ notice to the Executive, shall have the right to withhold payment to
the Executive for any further payments and benefits due him under this Agreement. In the event that
a court of competent jurisdiction or an arbitrator (acting in accordance with Article XI of this
Agreement), determines that the Executive has materially breached Section 5.2 above, the Executive
shall have no right to receive such withheld payments and benefits. In the event that payments and
benefits are withheld and a court of competent jurisdiction or arbitrator subsequently determines
that the Executive did not materially breach Section 5.2 above, the withheld payments and benefits
shall be paid to the Executive 45 days after the decision of the court or arbitrator becomes final
and non-appealable. The existence of this right shall not preclude any other rights and remedies at
law or in equity that the Corporation may have.

5.4 ALLOCATION OF CONSIDERATION. The parties agree that the value attributable to the
restrictive covenants set forth in this Article V is $1,500,000 for the 12 months that such
restrictions are in effect and that the Executive is entitled to receive total consideration under
this Agreement (including cash payments and restricted stock) that is equal to or greater than such
amount.

ARTICLE VI

EMPLOYMENT PERIOD

6.1 DURATION. The Employment Period shall commence on January 1, 2011, and shall
expire at the midnight between January 1, 2014, and January 2, 2014. In the event that the
Employment Period ends and no new employment agreement is signed by both the Corporation and the
Executive, such occurrences (or non-occurrences), either singly or in combination, shall not
entitle the Executive to any severance-related payment or benefit of any kind, either under this
Agreement or under any severance plan of the Corporation, regardless of whether the Executive does
or does not continue working for the Corporation without an employment agreement following the end
of the Employment Period. As described in the paragraph above defining
Change-in-Control-Related-Termination, the Executive’s Termination (whether voluntary or
involuntary, and for whatever reason) following expiration of this Agreement shall not entitle him
to any severance payments or post-Termination benefits payments under this Agreement unless such
Termination occurs within one year after this Agreement expires and meets the

 

14

 

definition of
Change-in-Control-Related-Termination set forth above or such Termination precedes a Change in
Control that occurs within three months after the expiration of this Agreement and is part of a set
of circumstances that meet the definition of a Termination In Anticipation of a Change in Control.
This Agreement will not be automatically renewed at the end of the Employment Period in the event
that the Executive continues to work for the Corporation without a new employment contract having
been signed. This Agreement can be renewed only by a writing approved by the Board and signed by
the Executive and the Corporation’s Chairman of the Board. The Executive agrees to inform the
Board in writing between December 1, 2012, and December 31, 2012, as to whether he is interested in
negotiating a renewal of this Agreement for the period beginning January 1, 2014. This Agreement
may, by mutual written agreement, be renewed for two one-year terms (each, a “Renewal Term”) upon
the written agreement of the parties on or before the expiration date of the Employment Period or
first Renewal Term.

6.2 EARLY TERMINATION. This Agreement shall be terminated prior to the end of the
Employment Period for the following reasons or upon the occurrence of the following events:

	 	(a)	 	The Corporation’s Termination of the Executive’s employment
without Cause or the Executive’s resignation for Good Reason;

	 
	 	(b)	 	Termination of the Executive’s employment for Cause;

	 
	 	(c)	 	Death of the Executive;

	 
	 	(d)	 	Disability of the Executive; or

	 
	 	(e)	 	Voluntary resignation of the Executive (not for Good Reason).

ARTICLE VII

EARLY TERMINATION WITHOUT CHANGE IN CONTROL

7.1 TERMINATION WITHOUT CAUSE/RESIGNATION FOR GOOD REASON.

(a) In the event of an early termination of this Agreement that is due to the Executive’s
Involuntary Separation from Service without Cause, or due to the Executive’s resignation for Good
Reason, the Executive, contingent upon his timely execution and return of the Release, shall be
entitled to the payments and benefits described in clauses (i)-(iii) immediately below.

(i) Subject to Section 9.2 below, during the remainder of the Employment Period, the
Corporation shall continue to pay the Executive his Base Salary except that, if the Termination
occurs at a time when the remainder of the Employment Period is less than 12 months, the
Corporation shall, 65 days after such Termination, pay the Executive a lump sum amount equal to
100% of the Executive’s annual Base Salary;

 

15

 

(ii) A cash bonus in an amount based on the extent of achievement of the performance goals set
forth at Section 4.2 above during the months worked by the Executive in the year in which the
Executive’s Termination occurred, provided that any such determination shall be made by the Board
in accordance with the procedures set forth in Section 4.2 above and following the close of the
performance year in which the Executive’s Termination occurred and no later than March 10 of the
year immediately following such performance year, with any payment to the Executive to be made no
later than March 15 of the year immediately following the calendar year in which he is Terminated,
provided that, should the Executive be Terminated without Cause or resign for Good Reason after the
completion of a calendar year but before his bonus under Section 4.2 above has been paid, any bonus
that he earned under Section 4.2 above will be paid to him just as it would have but for his
Termination without Cause or resignation for Good Reason; and

(iii) All rights which have accrued under the WGI 1996 Stock Plan and the WGI 2010 Stock Plan
as of the time of the Termination and all of the outstanding WGI stock options, restricted stock
awards and other equity-based awards granted by the Corporation or WGI to the Executive shall
become fully vested and, to the extent allowed by law, immediately exercisable in full on the date
of the Executive’s Involuntary Separation from Service, and any unvested cash awards shall be paid
to him within the applicable Short-Term Deferral Period, except that any acceleration of vesting,
change in the date of initial exercisability, or payment made under this Section 7.1 (a) (iii) must
comply with Section 9.2 below.

7.2 VOLUNTARY RESIGNATION OR TERMINATION FOR CAUSE. In the event of an early
termination of this Agreement because of the voluntary resignation of the Executive or because of
the Executive’s Involuntary Separation from Service for Cause, the Executive will receive his Base
Salary through the date of such voluntary resignation or termination, the Executive shall receive
no cash bonuses under Section 4.2 above for any years remaining in the Employment Period which have
not ended as of the date of such voluntary resignation or Termination of the Executive’s employment
for Cause, even if the performance goals set forth in Section 4.2 above for such years are
achieved, and the Executive and his eligible dependents will receive, subject to Section 9.2 below,
such benefits as they may be entitled under the terms of the WGI 1996 Stock Plan; the WGI 2010
Stock Plan; and the employee benefit programs, plans and arrangements of the Corporation described
in Section 10.1 below.

7.3 DEATH. In the event of an early termination of this Agreement because of the
death of the Executive, the Executive’s spouse, if living (if not, his estate) will be entitled to
and shall receive (i) the Executive’s Base Salary at the rate specified in Section 4.1 above
through the date of the Executive’s death, (ii) an amount in cash equal to the target cash bonus
that would have been due if the Corporation had achieved the performance goals referenced in
Section 4.2 above for the year in which the Executive’s death occurs (payable within three months
after the date of the Executive’s death, but in any event no later than two and one-half months
following the end of the calendar year in which the Executive’s death occurs), but no other amounts
in respect of the potential cash bonuses under Section 4.2 above, (iii) immediate vesting of all
LTI awards that have been awarded and earned pursuant to Section 4.3 above, and (iv) such survivor
and other benefits, including health care continuation benefits, as they may be entitled under the
terms of the employee benefit programs, plans and arrangements described in Section 10.1 and under
the WGI 1996 Stock Plan and the WGI 2010 Stock Plan.

 

16

 

7.4 DISABILITY. In the event that the Executive is unable to work for a medical
reason, the Executive will be entitled to and shall receive any disability payments due him under
any short-term or long-term disability plan sponsored by the Corporation, WGI, or any Affiliate. To
the extent that such disability plan payments are less than the actual base salary that the
Executive is being paid at the time of his absence, the Corporation will pay the Executive, on its
regular pay dates for executives (which are never less frequently than monthly), supplemental
payments equal to the difference between the Executive’s actual base salary at the time of his
absence and the amount that he is receiving from the short-term and/or long-term disability plan.
Any supplemental payments made by the Corporation under the immediately preceding sentence, as well
as any salary payments to the Executive, will end on the date of the Executive’s Separation from
Service. Contingent upon
his timely execution and return of the Release (if and to the extent the Executive is physically
and mentally capable of giving a release), the Executive, in the event of his Separation from
Service as a result of Disability, shall be entitled to: (i) an amount in cash equal to the target
cash bonus that would have been due if the Corporation had achieved the performance goals set forth
in Section 4.2 above for the year in which the Executive’s Separation from Service occurs (payable
no later than the last day of the Short-Term Deferral Period following the Executive’s Separation
from Service), but no other amounts in respect of the potential cash bonuses under Section 4.2
above, and (ii) immediate vesting of all LTI awards that have been awarded pursuant to Section 4.3
above. Without regard to whether the Executive timely executes and returns the Release, in the
event of his Separation from Service as a result of Disability, the Executive, subject to Section
9.2 below, shall be entitled to any benefits due him (a) under the terms of the employee benefit
programs, plans and arrangements described in Section 10.1 below and (b) under the WGI 1996 Stock
Plan and WGI 2010 Stock Plan. It is expressly understood and agreed that a Separation from Service
as a result of Disability shall not entitle the Executive to those payments and benefits that he
would have received under Section 7.1(a) above based on an Involuntary Separation from Service
without Cause.

ARTICLE VIII

CHANGE-IN-CONTROL-RELATED-TERMINATION

8.1 SEVERANCE COMPENSATION.

(a) In the event of a Change-in-Control-Related-Termination, the Executive, subject to the
280G cutback set forth in Section 8.2 below and contingent upon his timely execution and return of
the Release, shall be entitled to the following:

(i) a lump sum cash payment in an amount equal to 300 percent of the Executive’s Severance
Compensation, which shall be paid by the Corporation no later than the earlier of: (a) 90
days after the Executive’s Separation from Service (or, if applicable, 90 days after the date that
the Executive’s Separation from Service becomes a Termination in Anticipation of a Change in
Control) and (b) the end of the Short-Term Deferral Period, provided that such lump sum payment
shall be reduced by: (1) any amount that the Executive is entitled to receive under Section
7.1(a)(i) above, with the timing of any payments due under Section 7.1(a)(i) above to be made as
specified in said Section 7.1(a)(i) rather than as specified in this Section 8.1(a)(i), and (2) any
280G cutback made under Section 8.2 below;

 

17

 

(ii) in the event that the Executive’s Termination occurs on a day other than the last day or
first day of a calendar year, a lump sum cash payment (which shall be paid by the Corporation at
the same time the payment described in Section 8.1(a)(i) hereof is paid) in an amount equal to (a)
the aggregate annual target opportunity the Executive could have earned under Sections 4.2 and 4.3
above, the WGI 1996 Stock Plan, the WGI 2010 Stock Plan and any successor to either such plan, and
any other incentive plans covering the Executive during the calendar year during which the
Executive’s Termination occurs (determined as if all applicable goals and targets had been
satisfied in full), multiplied by (b) a fraction, the numerator of which is the number of days
during the period beginning on the first day of such calendar year and ending on the date of the
Executive’s Termination, and the
denominator of which is 365, provided that such lump sum payment shall be in lieu of any cash bonus
that the Executive would otherwise be entitled to receive under Section 7.1(a)(ii) above; and

(iii) acceleration of vesting as described in Section 7.1(a) (iii) above.

8.2 280G CUTBACK. Notwithstanding anything to the contrary in this Agreement, if the
payments and benefits provided for in this Agreement, together with any other payments and benefits
that the Executive has the right to receive from the Corporation, WGI and/or any of the Affiliates,
would constitute a “parachute payment” (as defined in Section 280G(b)(2) of the Code), then the
payments and benefits provided hereunder (beginning with any payment to be paid in cash hereunder)
shall be reduced (but not below zero) so that the present value of such total amounts and benefits
received by the Executive will be $1.00 less than three times the Executive’s Base Amount and so
that no portion of such amounts and benefits received by the Executive shall be subject to the
excise tax imposed by Section 4999 of the Code. The determination as to whether any such reduction
in the amount of the benefits provided hereunder is necessary shall be in accordance with the
process described herein.

The Compensation Committee, with advice of counsel and such advisors to counsel as the
Compensation Committee deems necessary, shall promptly, following the Executive’s Separation from
Service, make an initial determination as to whether a 280G cutback, as described in the
immediately preceding paragraph, is required and the amount of any such cutback. Such initial
determination shall be delivered to the Executive no later than the 21st day following
his Separation from Service. In the event that the Executive wishes to challenge the initial
determination, the Corporation shall reimburse the Executive for reasonable attorneys’ fees that he
incurs in seeking advice concerning such initial determination, provided that such reimbursement
shall be conditional on the Corporation and the Executive’s chosen law firm, no later than 30 days
following the Executive’s Separation from Service, signing a mutually acceptable engagement letter
that sets forth a budget, hourly rates, a monthly billing arrangement for the law firm, and
estimated fees for outside consultants (such as CPA firms and/or benefit consulting firms that may
advise the law firm). Any challenge that the Executive wishes to make to the initial determination
shall be made by written notice no later than 30 days following his receipt of the Corporation’s
initial determination. The Corporation and the Executive shall work together in good faith to
resolve, within 21 days of the notice of challenge from the Executive, their disputes concerning
the initial determination, and the Corporation shall make any necessary cutbacks to payments due to
the Executive hereunder within three days after such resolution.

 

18

 

If a reduced payment is called for in accordance with this Section 8.2 and, through error or
otherwise, the payments and benefits already received by the Executive under this Agreement, when
aggregated with any other payments and benefits from the Corporation or WGI (or any of the
Affiliates) used in determining if a “parachute payment” exists, exceed $1.00 less than three times
the Executive’s Base Amount, then the Executive shall repay, upon 30 days’ written notice (with
supporting calculations explaining the demand), such excess to the Corporation upon notification
that an overpayment has been made. In the event that a 280G cutback in the Executive’s compensation
is made under this Section 8.2 and the Executive subsequently becomes convinced that it was made in
error, then he shall promptly
notify the Corporation of such alleged error. The deadline for the Executive to notify the
Corporation of any such alleged error shall be 10 days after his timely filing with the Internal
Revenue Service of his first federal income tax return due following his Separation from Service.
Any claim of the Executive that an error was made in computing the 280G cutback shall be forever
waived if not made within the 10-day period described in the immediately preceding sentence. In
the event that the Executive claims that an error was made in connection with a 280G cutback in his
compensation, then the Executive and the Corporation shall work together in good faith for a period
no longer than 60 days in attempting to resolve the claim. If the claim is not resolved within
such 60-day period, then the Executive, no later than 14 days following the end of the 60-day
period, shall make demand with the American Arbitration Association for arbitration of the claim
under Article XI of this Agreement. If the Executive fails to make demand for arbitration of the
claim with the American Arbitration Association within such 14-day period, then any rights he might
have had to recover against the Corporation for an error made in the 280G cutback shall be forever
waived. If the Executive makes a timely demand for arbitration with regard to an alleged error in
the 280G cutback, the parties agree to proceed to arbitration promptly and to take all reasonable
steps to cause the arbitration proceeding to occur within 90 days after the Executive makes demand
with the American Arbitration Association for such arbitration. In the event that the arbitrator
finds that the Corporation is indebted to the Executive due to an error made in connection with the
280G cutback, the Corporation shall pay the Executive the amount of the arbitrator’s award on the
first Business Day following 45 days after the decision of the arbitrator becomes final.

8.3 OTHER 280G /4999 ISSUES. In the unlikely event that, despite the 280G cutback
procedures set forth above, any of the payments or benefits that the Executive has the right to
receive under this Agreement from the Corporation or any of the Affiliates (the “Payments”) are
later determined to be subject to the excise tax imposed by Section 4999 of the Code (in connection
with Section 280G of the Code), or any interest or penalties with respect to such excise tax (such
excise tax, together with any such interest or penalties, are hereinafter collectively referred to
as the “Section 4999 Tax”), the Corporation shall pay to the Executive an additional payment (a
“Section 4999 Gross-up Payment”) in an amount such that, after payment by the Executive of all
Section 4999 Tax (including any interest or penalties imposed with respect to such taxes),
including any excise tax imposed on any Section 4999 Gross-up Payment, the Executive retains an
amount of the Section 4999 Gross-up Payment equal to the excise tax imposed upon the Payments.

 

19

 

The Executive shall notify the Corporation immediately in writing following the receipt of any
claim by the Internal Revenue Service which, if successful, would require the Corporation to make a
Section 4999 Gross-up Payment (or a gross-up payment in excess of that, if any, initially
determined by the Compensation Committee). The Corporation shall notify the Executive in writing
at least 15 days prior to the due date of any response required with respect to such claim if it
plans to contest the claim. If the Corporation decides to contest such claim, then the Executive
shall cooperate fully with the Corporation in such action; provided, however, the Corporation shall
bear and pay all costs and expenses (including additional interest and penalties) incurred in
connection with such action and shall indemnify and hold the Executive harmless, on an after-tax
basis, for any Section 4999 Tax, or income tax, including interest and penalties with respect
thereto, imposed as a result of the Corporation’s action. If, as a result of the Corporation’s
action with respect to a claim, the Executive receives a refund of any amount paid by the
Corporation with respect to such claim, then the Executive shall, within 10 days of receipt, pay
such refund to the Corporation. If the Corporation fails to timely notify the Executive whether it
will contest such claim or the Corporation determines not to contest such claim, then the
Corporation shall, on the first Business Day following 30 days after its receipt from the Executive
of notice of the claim by the Internal Revenue Service, pay to the Executive the portion of such
claim, if any, which it has not previously paid to the Executive. In connection with any claim
made by the Executive under this Section 8.3, the Executive shall provide the Corporation with
adequate substantiation, including his federal income tax returns and all attachments thereto. If,
after compliance with the procedures set forth in this paragraph, the Executive is required to pay
taxes to a taxing authority as a result of Section 280G of the Code, the Executive shall notify the
Corporation within 15 days after making such payment and shall provide the Corporation with such
substantiation as it shall reasonably request. The Corporation shall reimburse the Executive for
such taxes (and any penalties and interest thereon that he could not have avoided by paying the
amounts due once the Corporation determined that it did not intend to contest same) on the first
Business Day following 60 days after its receipt of such notice, provided that in no event will
such payment be made later than the end of the Executive’s taxable year next following his taxable
year in which he remits the subject taxes, penalties and interest to the taxing authority.

8.4 SUCCESSORS BOUND. After a Change in Control has occurred, this Agreement shall
bind any successor of the Corporation (whether direct or indirect, by purchase, merger,
consolidation or otherwise) in the same manner and to the same extent that the Corporation would be
obligated under this Agreement if no succession had taken place. In the case of any transaction in
which a successor of the Corporation (that becomes such after a Change in Control has occurred)
would not, by the foregoing provision or by operation of law, be bound by this Agreement, the
Corporation and WGI shall require, as part of any purchase and sale documents or other applicable
documents, that such successor: (a) expressly and unconditionally assume, and agree to perform the
Corporation’s obligations under this Agreement, in the same manner and to the same extent that the
Corporation would be required to perform if no such succession had taken place, and (b) agree to
impose upon its successors (as well as any person or entity to which it assigns all or
substantially all of the business and/or assets that it acquired from the Corporation) the same
requirements concerning this Agreement that the Corporation imposed upon its successor.

8.5 NON-DUPLICATION OF BENEFITS. Except to the extent that this Agreement provides
otherwise, the benefits payable under this Article VIII shall be payable in addition to, and not in
lieu of, all other accrued or vested or earned but deferred compensation, rights, options and other
benefits that may be owed to the Executive following Termination (which are not contingent on any
Change in Control preceding such termination), including accrued vacation or sick pay, amounts or
benefits payable under any bonus or other compensation plans, any life insurance plan, health
plan, disability plan, or any similar or successor plans. However, as described above, any
payments and benefits due the Executive under Section 7.1(a) (i) above must be paid under that
section and then deducted from any payments and benefits he would have received under this Article
VIII if he had not been due them under Section 7.1(a) (i) above.

ARTICLE IX

GENERAL PROVISIONS RE POST-TERMINATION PAYMENTS

9.1 MITIGATION NOT REQUIRED. The Executive shall not be required to mitigate the
amount of any payment provided for in Article VII or Article VIII above by seeking employment or
otherwise. Except to the extent provided in Section 5.3 above, the amount of any payment provided
for in Article VII or Article VIII above shall not be reduced by any compensation or remuneration
earned by the Executive as the result of employment with another employer, or self-employment, or
as a partner, or in any other capacity, after the date of his Separation from Service.

9.2 409A-RELATED PROVISIONS. Each payment to the Executive of an amount following his
Termination shall constitute a “separate payment” for purposes of Section 409A. Any payments to be
made under this Agreement to the Executive upon his Termination, and the timing of such payments,
shall be made only at such time the Executive shall have realized a Separation from Service. All
amounts or benefits payable to the Executive under this Agreement following his Termination that
are not payable within the Short-Term Deferral Period and that are payable within six months
following such Termination shall be accrued and paid on the earlier of: (1) the first day of the
seventh month following the date of Separation from Service, or (2) if earlier than the end of such
six-month period, within 10 days following the date of the Executive’s death. To the extent that
Section 409A applies to this Agreement, this Agreement shall be interpreted in accordance with
Section 409A, including any applicable interpretive guidance previously issued or that may be
issued after the date of this Agreement (“409A Guidance”), and any ambiguous term or undefined term
herein shall be interpreted in a manner that causes the term to meet the definition of that term
that complies with Section 409A and 409A Guidance. Notwithstanding any other provision of this
Agreement to the contrary, it is intended that any payment or benefit provided for in this
Agreement that constitutes “nonqualified deferred compensation,” as that term is defined in Section
409A, shall be provided and issued in a manner, and at such time and in such form, as complies with
the applicable requirements of Section 409A. Any provision in this Agreement that would result in
the imposition of excise taxes or any other taxes under Section 409A shall be void and without
effect. To the extent permitted under Section 409A, the parties shall reform the provision,
provided such reformation shall not subject the Executive to additional tax or interest and the
Corporation shall not be required to incur any additional compensation costs as a result of the
reformation. In addition, any provision that is required to appear in this Agreement for purposes
of Section 409A compliance and that is not expressly set forth shall be deemed to be set forth
herein, and this Agreement shall be administered in all respects as if such provision were
expressly set
forth. References in this Agreement to Section 409A include rules, regulations, and guidance of
general application issued by the Department of the Treasury under Section 409A. Unless this
Agreement expressly specifies a different time for a recurring payment to be made or recurring
benefit to be received, recurring amounts or recurring benefits payable to the Executive under this
Agreement following his Termination shall be paid on the regular payroll payment dates of the
Corporation for payment of such amounts or benefits, provided that such regular payroll payment
dates shall be no less frequently than monthly.

ARTICLE X

EMPLOYEE BENEFITS

10.1 BENEFITS DURING EMPLOYMENT. Throughout the Employment Period, the Executive
shall be entitled to participate in such retirement, bonus, disability, life, sickness, accident,
dental, medical and health benefits and other ERISA-covered employee benefit programs, plans and
arrangements of the Corporation that are in effect, and in any successor or additional employee
benefit programs, plans or arrangements that may be established by the Corporation, as and to the
extent any such employee benefit programs, plans and arrangements are or may from time to time be
in effect.

10.2 POST-TERMINATION BENEFITS. The Corporation will provide to the Executive and his
eligible dependents certain post-Termination employee benefits (or the cost of same) to the limited
extent described in this Section 10.2. If the Executive is Terminated for Cause, the Corporation
shall have no obligation to provide the Executive (or his eligible dependents with any of the
post-Termination employee benefits (or the costs of same) granted to him in this Section 10.2.
Furthermore, any post-Termination medical and dental benefits granted to the Executive under this
Section 10.2 shall terminate when the Executive subsequently becomes (a) an employee of another
employer (or becomes self-employed under an arrangement that allows him and his eligible dependents
to elect coverage under the group medical plan offered to employees of the entity through which he
is self-employed), or (b) eligible to receive benefits through Medicare. The Executive shall
promptly give the Corporation notice of such subsequent employment, self-employment or Medicare
eligibility (if such Medicare eligibility is based on disability or any other factor except
attainment of Medicare eligibility age). Any post-Termination medical or dental coverage that the
Executive receives under this Section 10.2 shall be counted against any obligation of the
Corporation (or WGI or any Affiliate) to provide him with coverage under COBRA. Any dependent
coverage provided to the Executive’s eligible dependents under the Corporation’s medical or dental
plans shall terminate at the same time that the Executive’s post-Termination coverage terminates,
except that, in a situation in which the Executive’s coverage ends because of his death or because
Medicare (or coverage under a national healthcare arrangement, as described below) becomes
available to him, his eligible dependents shall be notified of their COBRA rights, if any, and
provided with COBRA coverage if required by law. Subject to the conditions set forth in this
Section 10.2, the limited post-Termination benefits that the Corporation shall provide to the
Executive (and his eligible dependents) are:

(i) Contingent upon the Executive’s timely execution and return of the Release (unless excused
under Section 7.4 above), the Corporation will pay the Executive a cash payment in an amount equal
to the Executive’s costs for 24 months of life insurance coverage for himself and his spouse (if
his spouse was covered by a Corporation-sponsored life insurance plan on the

 

22

 

day prior to the
Executive’s Termination) under the life insurance benefits plan maintained by the Corporation on
the day prior to the Executive’s Termination. The Executive shall not be entitled to the payment
described in this Section 10.2 (i) in the event that he voluntarily resigns from the Corporation.
The Corporation will make this payment within the Short-Term Deferral Period.

(ii) Contingent upon the Executive’s timely execution and return of the Release (unless
excused under Section 7.4 above), Executive and his eligible dependents (if such dependent was
covered under the medical and dental insurance benefit plans sponsored by the Corporation on the
day prior to the Executive’s Termination of employment) shall continue to be covered under such
plans during the period beginning on the date of the Executive’s Termination and continuing until
the end of the period for which the Executive (and his eligible dependents) would be entitled to
COBRA coverage under section 4980B of the Code (if the Executive had elected such coverage and paid
the applicable premiums). Such coverage shall be provided to the Executive at a cost that is no
greater than the lesser of: (a) the cost of such coverage paid by the Executive immediately
prior to the Executive’s Termination or (b) the cost of such coverage paid by the Executive
immediately prior to the subject Change in Control, if the Executive’s Termination was a
Change-in-Control-Related-Termination. Furthermore, if the Executive’s Termination was a
Change-in-Control-Related-Termination, the benefits and terms of each such coverage provided under
this Section 10.2(ii) shall be no less favorable in the aggregate than that provided to the
Executive immediately prior to the Change in Control, unless changes made to the Corporation’s
group medical and dental insurance make it impossible for the Corporation to provide benefits and
terms comparable in the aggregate to those provided immediately prior to the Change in Control. If
the coverage provided to the Executive (and his eligible dependents) under this Section 10.2(ii)
will have adverse tax consequences to the Executive as compared to the tax consequences associated
with similar coverage provided to an active executive employed by the Corporation, then the
Corporation shall attempt to arrange substantially similar coverage through individual policies
that do not have such adverse tax consequences or otherwise pay to the Executive a cash payment to
make the Executive approximately whole (on an after-tax basis) for such adverse tax consequences.
Such payment, if any, shall be estimated and paid within the Short-Term Deferral Period. The
Executive shall not be entitled to any of the benefits described in this Section 10.2 (ii) in the
event that he voluntarily resigns from the Corporation.

 

23

 

(iii) Under the following circumstances, the Executive and his eligible dependents shall have
the right to the additional post-Termination medical coverage as described in this Section 10.2
(iii): (a) if, within 30 days following expiration of the Employment Period, the Corporation
involuntarily terminates the Executive
(not for an event that meets the definition of Cause set forth above) and such Termination
does not constitute a Change-in-Control-Related-Termination; or (b) if the Executive obtains
medical coverage under Section 10.2 (ii) above and, at the end of the period described in 10.2 (ii)
above, still is not: (x) an employee of another employer (or self-employed under an arrangement
that allows him and his eligible dependents to elect coverage under the group medical plan offered
to employees of the entity through which he is self-employed), (y) eligible to receive benefits
through Medicare, or (z) eligible to purchase medical coverage under a national healthcare program
that provides benefits comparable to (or better than) those provided by Medicare at a cost to the
Executive for his coverage that is no greater than $15,000 a year (indexed for inflation based on
the Consumer Price Index for All Urban Consumers from 12/31/10 forward). If the Executive and his
eligible dependents have a right to additional post-Termination medical coverage under this Section
10.2 (iii), then, upon cessation of the Executive’s medical coverage based on either (a) or (b) of
this Section 10.2 (iii), the Corporation shall either: (A) locate a medical insurance carrier that
will provide medical coverage (comparable to the employee group medical coverage then offered by
the Corporation to its Houston office employees generally) to the Executive and his eligible
dependents, at a cost comparable to the COBRA costs paid by ex-employees who, along with their
eligible dependents (if any), remain covered on the Corporation-sponsored group medical plan for
Houston office employees generally, with the Corporation having the option, but not the obligation,
to partially subsidize the cost of any such medical coverage to make the cost of it to the
Executive comparable to the COBRA rate; or (B) permit the Executive and his eligible dependents the
opportunity, under this Section 10.2 (iii), to elect, solely at the Executive’s expense, to
continue coverage under the Corporation’s group medical plan offered to Houston office employees
generally and dental benefit plan as in effect at such time (the “Medical/Dental Plans”). The
Executive and/or his eligible dependents shall make such election by giving notice within the
later of 30 days: (a) from the Termination of the Executive’s employment with the
Corporation, or (b) from the date that the Executive’s medical coverage under Section 10.2 (ii)
above ends and, if it is not made within such period, such election right under this Section 10.2
(iii) shall be forever forfeited. The cost of such post-Termination coverage under the
Medical/Dental Plans to be charged to the Executive shall be the cost charged to participants in
the Medical/Dental Plans who have elected COBRA under such plans. The coverage under this Section
10.2 (iii) shall terminate in the event that the Executive fails to make timely monthly payments to
the Corporation in the amount of the monthly COBRA costs then being paid by other ex-employees of
the Corporation. Any coverage provided under this Section 10.2 (iii) shall terminate immediately if
the Executive becomes: (x) an employee of another employer (or self-employed under an arrangement
that allows him and his eligible dependents) to elect coverage under the group medical plan offered
to employees of the entity through which he is self-employed), (y) eligible to receive benefits
through Medicare, or (z) eligible to purchase medical coverage under a national healthcare program
that provides benefits comparable to (or better than) those provided by Medicare at a cost to the
Executive for his coverage that is no greater than $15,000 a year (indexed for inflation based on
the Consumer Price Index for All Urban Consumers from 12/31/11 forward).

ARTICLE XI

MANDATORY ARBITRATION

11.1 MANDATORY ARBITRATION PROVISION. Any dispute, claim or controversy arising out
of or related in any way to this Agreement, including its enforceability, validity, or
interpretation, or related in any way to the Executive’s employment with, or provision of services
to, the Corporation, WGI or any Affiliate, shall be submitted to and resolved by binding
arbitration with the American Arbitration Association (“AAA”) in Houston, Texas, in accordance with
the rules of the AAA pertaining to employment disputes. This mandatory arbitration section shall
also apply to any claim that the Executive might assert against any officer, director, or manager
of the Corporation, WGI or any Affiliate. One arbitrator shall be used. Judgment upon the award
rendered by the arbitrator may be entered in any court having jurisdiction. It is specifically
agreed that this section on arbitration shall be binding on the Executive’s heirs, administrators,
and personal representatives. This section on arbitration shall be governed by the Federal
Arbitration Act. Nothing contained in this section on mandatory arbitration shall prevent the
Corporation from seeking injunctive relief against the Executive for violation of the sections of
this Agreement pertaining to intellectual property, protection of Confidential Information, and/or
non-competition or non-solicitation. Any provision of this section on mandatory arbitration that
is found to be unconscionable or otherwise unenforceable shall be severed and this section on
mandatory arbitration shall be enforced without the severed provision. This section on mandatory
arbitration shall not apply to any claim that, under applicable law, is not subject to arbitration.
This section on mandatory arbitration shall survive the termination of this Agreement unless and
until the Executive and the Corporation enter into a new employment agreement that specifically
addresses the subject of mandatory arbitration.

MISCELLANEOUS

13.1 ENTIRE AGREEMENT. This Agreement constitutes the entire understanding of the
Executive and the Corporation with respect to the subject matter hereof and supersedes any and all
prior understandings on the subjects contained herein, written or oral, and all amendments thereto,
save and except for the continuing applicability and participation of the Executive in the employee
benefit plans and arrangements described in Article X above, and the applicability of the terms and
provisions of the WGI 1996 Stock Plan, the WGI 2010 Stock Plan, the Restricted Stock Award
Agreements and Stock Option Agreements related to the award of restricted stock shares and grant of

benefit plans or arrangements available to any employee or group of employees.

 

26

 

13.2 PRIOR INDEMNIFICATION AGREEMENT. Nothing contained in this Agreement shall
diminish or impair the validity, application, and enforceability of that certain indemnification
agreement dated as of May 27, 2009, between the Executive and WGI.

13.3 MODIFICATION. Nothing in this Agreement shall affect the Corporation’s, WGI’s or
the Affiliates’ rights to amend or terminate any of their employee benefit plans, as permitted
under applicable law and the respective terms of such plans. Except as provided in the immediately
preceding sentence, this Agreement shall not be varied, altered, modified, canceled, changed, or in
any way amended, nor any provision hereof waived, except by mutual agreement of the parties in a
written instrument executed by the parties hereto or their legal representatives. The parties
agree to further amend this Agreement in the event that an amendment is necessary or desirable to
address the requirements of Section 409A.

13.4 SEVERABILITY. In the event that any provision or portion of this Agreement shall
be determined to be invalid or unenforceable for any reason, the remaining provisions of this
Agreement shall be unaffected thereby and shall remain in full force and effect, provided, that, if
the unenforceability of any provision is because of the breadth of its scope, the duration of such
provision or the geographical area covered thereby, the parties agree that such provision shall be
amended, as determined by the court, so as to reduce the breadth of the scope or the duration
and/or geographical area of such provision such that, in its reduced form, said provision shall
then be enforceable.

13.5 SURVIVAL OF CERTAIN PROVISIONS. The parties’ obligations under Sections 8.1, 8.2
and 8.3 hereof and Articles X and XI hereof, as well as the parties’ obligations with regard to
reformation under Section 9.2 hereof, shall survive the termination of this Agreement. The
following shall also survive the termination of this Agreement: (a) Executive’s obligations under
Sections 2.2, 5.1, 5.2, 9.2, and 10.2 hereof, and (b) the Corporation’s obligations under Sections
4.3, 7.1, 7.2, 7.4, and 8.4 hereof. Furthermore, the Corporation’s obligations to the Executive’s
spouse (or estate) under Section 7.3 above shall survive any termination of this Agreement that

above or required by federal bankruptcy law or other applicable law, the Corporation’s obligation
to pay any amounts, and to provide benefits continuation or any other benefits under this
Agreement, shall be absolute and unconditional. The Corporation’s obligations to the Executive
under this Agreement shall not be affected by any circumstances, including any set-off,
counterclaim, recoupment, defense or other right that the Corporation or any of the Affiliates may
have against the Executive. All benefits due to the Executive under this Agreement are unfunded
and unsecured and are payable out of the general funds of the Corporation. At its option, the
Corporation may establish as grantor a “grantor trust” for the payment of benefits and obligations
hereunder, the assets of which shall be at all times subject to the claims of creditors as provided
for in such trust.

 

27

and 401(a) (1) of ERISA.

Exhibit 1

Performance Conditions Related to Annual Cash Bonus Awards

The Executive is eligible for an annual cash bonus award for 2011 subject to the achievement of
performance goals set out below based on an objective compensation standard to be determined by the
Compensation Committee (the “Committee”):

	 	•	 	50% of bonus award tied to achievement of earnings per share (“EPS”)
goals;

	 
	 	•	 	10% of bonus award tied to achievement of days of sales outstanding
(“DSO”) goals;

	 
	 	•	 	10% of bonus award tied to achievement of objective health, safety and
environmental (“HSE”) goals; and

	 
	 	•	 	30% of bonus award tied to achievement of personal performance goals,
including: earnings, cash flow, customer satisfaction, revenues, financial
return ratios, expense reduction, and market performance.

For 2012 and 2013, the Committee may vary the performance goals for the annual cash bonus award to
the extent allowed by the management incentive plan.

For target achievement of the specified performance goals, a bonus in the amount of the Executive’s
Base Salary will be awarded. For maximum achievement of the specified performance goals, in the
Committee’s sole discretion, a bonus of up to 150% of Base Salary will be awarded.

 

30

 

Exhibit 2

Performance Conditions Related to Long-Term Incentive Awards

The Executive’s annual target long-term incentive award shall be $4 million. This award will be
earned in shares or restricted stock units, to the extent permissible, with the remainder of the
award earned in cash or other forms permitted under the WGI 2010 Stock Plan. This award will be
earned annually and will vest in the manner set forth in the Agreement. For 2011 the amount of the
award will be determined based upon the achievement of the long-term performance goals outlined
below based on an objective compensation standard to be determined by the Compensation Committee
(the “Committee”):

	 	•	 	50% of award tied to achievement of Total Shareholder Return (“TSR”) goals
(i.e., stock price appreciation and dividend return);

	 	•	 	20% of award tied to achievement of objective health, safety and environmental
(“HSE”) goals; and

	 	•	 	30% of award tied to achievement of personal performance goals, including:
earnings, cash flow, customer satisfaction, revenues, financial return ratios, expense
reduction, and market performance.

For 2012 and 2013, the Committee may vary the performance goals for the long-term incentive award
to the extent allowed by the WGI 2010 Stock Plan.

For target achievement of the specified performance goals, the target long-term incentive award
will be earned. For maximum achievement of goals as outlined above, in the Committee’s sole
discretion, a long term incentive award of up to 200% of the target award may be earned.

For the TSR portion of the award, TSR will be measured against a peer group of comparators
determined by the Committee. Potential award levels determined by the Committee are outlined
below:

	 	•	 	Up to 200% of the TSR portion of the award may be earned for TSR performance
within the top 2 companies of the comparator group.

	 	•	 	Up to 100% of the TSR portion of the award may be earned for TSR performance at
the median of the comparator group.

	 	•	 	None of the TSR portion of the award will be earned for TSR performance within
the bottom 2 companies of the comparator group.

For each of the objective health, safety and environmental goals and objective personal performance
goals, the achievement of these performance goals will be determined at the sole discretion of the
Committee.

extent that the 1/3
of the 2012 award
is payable in cash,
the cash must be
paid by this date.
To the extent that
the award is in a
form of equity, the
equity must belong
to Executive
without restriction
on this date
(Section 4.3 ¶ 2).
	 	Board determines
that Exec. earned
75% of target LTI
award of $4 million
that he could have
earned for 2012.
Therefore, by March
15 of 2013, Exec.
receives the
aggregate amount of
$1 million in cash
and/or in one of
more forms of
equity. The
unearned part of
the 2012 LTI award,
amounting to $5
million, is
forfeited forever.
Hypothetical #2:
Assuming
Hypothetical #1, on
May 1 of 2013,
Exec. voluntarily
resigns for
personal reasons.
The voluntary
resignation causes
forfeiture of (a)
2/3s
of the amount
of the LTI award
that Exec. earned
for 2012 (Section
4.3 ¶ 2); and (b)
100% of LTI awards
that Exec. might
have earned for
2013 (Section 4.3 ¶
2).

misrepresentation, a threat to withdraw or alter the offer prior to the expiration of the 21-day

to other executives who sign a release prior to the expiration of such time period.

Re: Bonus Agreement

Dear Mr. Harl:

Willbros United States Holdings, Inc. (the “Company”) and Robert R. Harl (“Mr. Harl”) are
entering into an Employment Agreement on the date hereof, such agreement to become effective as of
January 1, 2011 (the “Employment Agreement”).

In connection with the Employment Agreement, in consideration of Mr. Harl’s willingness to
enter into the Employment Agreement and to forego certain change in control benefits under the
Severance Plan (as defined in the Employment Agreement), which is being terminated as to Mr. Harl,
and in addition to the compensation set forth in the Employment Agreement, the Company hereby
agrees to grant and deliver to Mr. Harl shares of common stock in Willbros Group, Inc., the parent
company of the Company, as a bonus, as described below.

The number of shares to be granted to Mr. Harl (the “Bonus Shares”) shall be determined by
dividing $750,000 by the per share closing price of the Company’s common stock on The New York
Stock Exchange (the “NYSE”) on the date of this letter, or, if there is no trading on the NYSE on
such date, the per share closing price of the Company’s common stock on the NYSE on the next day
after the date of this letter on which trading occurs.

The Bonus Shares shall be granted to Mr. Harl under the WGI 2010 Stock Plan (as defined in the
Employment Agreement) and delivered (a) to Mr. Harl not later than March 15, 2014, if (i) Mr. Harl
remains employed by the Company on December 31, 2013, or (ii) Mr. Harl’s employment with the
Company has been terminated as a result of his Disability (as defined in the Employment Agreement)
or without Cause (as defined in the Employment Agreement) between January 1, 2011, and December 31,
2013, whether or not following or in connection with a Change in Control (as defined in the
Employment Agreement) or pursuant to a resignation for Good Reason (as defined in the Employment
Agreement) whether or not pursuant to a Change in Control; or (b) in the event Mr. Harl dies
between January 1, 2011, and December 31, 2013, to Mr. Harl’s spouse, if living (if not, to his
estate), not later than the 15th day of the third month after the end of the year in which he dies.
For avoidance of doubt, if Mr. Harl’s employment with the Company terminates prior to December 31,
2013, as a result of his voluntary termination (except for a resignation for Good Reason) or his
Involuntary Separation
from Service for Cause (as defined in the Employment Agreement), Mr. Harl will not be entitled
to receive any of the Bonus Shares.

 

 

 

Mr. Robert R. Harl

September 20, 2010

Delivery of the Bonus Shares shall constitute compensation to Mr. Harl and, therefore, shall
be subject to normal payroll withholding which will be paid by Mr. Harl to the Company in cash at
the time of delivery of the shares to Mr. Harl or, at Mr. Harl’s option, deducted from the Bonus
Shares.
