<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">As indicated within its quarterly report on Form 10-Q for the quarter ended March&nbsp;31, 2013, Willbros Group, Inc., a Delaware corporation (the
&#147;Registrant&#148;) has implemented a change to its operational and organizational structure in order to emphasize its commitment to its engineering, procurement and integrity services and to align its business interests to better reflect market
conditions. As a result, the Registrant created a new and fourth segment, <I>Professional Services</I>. <I>Professional Services</I>, together with <I>Oil&nbsp;&amp; Gas</I>, <I>Utility T&amp;D </I>and<I> Canada</I> represent the Registrant&#146;s
organizational structure for which its operating results are reported. The Registrant has revised its presentation of its reportable segments to reflect these changes and has retrospectively adjusted all comparable prior period annual information on
that basis. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">As indicated within its current report on Form 8-K dated January&nbsp;6, 2013, filed January&nbsp;10, 2013, the Registrant sold all of its
shares of capital in Willbros Middle East Limited, which held the Registrant&#146;s operations in Oman, to Interserve Holdings Limited, a company organized under the laws of the United Kingdom. The Registrant has revised its presentation of Willbros
Middle East Limited as a discontinued operation and retrospectively adjusted all comparable prior period annual information on that basis. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Registrant
is filing this current report on Form 8-K to reflect the impact of the segment realignment and the sale of Willbros Middle East Limited on previously issued financial statements. The impact of the segment realignment and the sale of Willbros Middle
East Limited is reflected in the following sections of the Registrant&#146;s 2012 Form 10-K, which has been revised and are included as Exhibits 99.1, 99.2, 99.3 and 99.4, respectively, to this current report on Form 8-K: </P>

Item 8.01. Other Events.
As indicated within its quarterly report on Form 10-Q for the quarter ended March 31, 2013, Willbros Group, Inc., a Delaware corporation (the
"Registrant") has implemented a change to its operational and organizational structure in order to emphasize its commitment to its engineering, procurement and integrity services and to align its business interests to better reflect market
conditions. As a result, the Registrant created a new and fourth segment,
Professional Services
.
Professional Services
, together with
Oil & Gas
,
Utility T&D
and
Canada
represent the Registrant's
organizational structure for which its operating results are reported. The Registrant has revised its presentation of its reportable segments to reflect these changes and has retrospectively adjusted all comparable prior period annual information on
that basis.
As indicated within its current report on Form 8-K dated January 6, 2013, filed January 10, 2013, the Registrant sold all of its
shares of capital in Willbros Middle East Limited, which held the Registrant's operations in Oman, to Interserve Holdings Limited, a company organized under the laws of the United Kingdom. The Registrant has revised its presentation of Willbros
Middle East Limited as a discontinued operation and retrospectively adjusted all comparable prior period annual information on that basis.
The Registrant
is filing this current report on Form 8-K to reflect the impact of the segment realignment and the sale of Willbros Middle East Limited on previously issued financial statements. The impact of the segment realignment and the sale of Willbros Middle
East Limited is reflected in the following sections of the Registrant's 2012 Form 10-K, which has been revised and are included as Exhibits 99.1, 99.2, 99.3 and 99.4, respectively, to this current report on Form 8-K:
•
Part I, Items 1. and 2. Business and Properties and Part I, Item 1A. Risk Factors;
•
Part II, Item 6. Selected Financial Data;
•
Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations; and
•
Part II, Item 8. Financial Statements and Supplementary Data and Part IV, Item 15(a) (2). Financial Statement Schedule.
This current report on Form 8-K speaks as of March 7, 2013, the date the Registrant filed its 2012 Form 10-K and does not reflect events occurring after
March 7, 2013, and none of the information included in this current report on Form 8-K modifies or updates the disclosures in the 2012 Form 10-K, other than as required to reflect the segment realignment and sale of Willbros Middle East Limited
as described above. Significant developments with respect to those disclosures, including changes to the Registrant's business, have occurred and are described in subsequent filings with the SEC, including the Registrant's quarterly report
on Form 10-Q for the quarters ended March 31, 2013 and June 30, 2013, and the Registrant's current reports on Form 8-K filed subsequent to the 2012 Form 10-K. This current report on Form 8-K should be read in conjunction with the 2012
Form 10-K and the Registrant's subsequent filings.
