Accordingly, upon consummation of the Merger, the Company’s shareholders immediately prior to the consummation of the Merger became shareholders of SWG Holdings.

Carson Water owns Southwest’s 96.6% interest in Centuri Construction Group Inc., a full-service natural gas piping contractor that provides industrial construction services through a family of businesses, and is the subsidiary through which Southwest operates its construction services segment. As a result of the distribution, Carson Water became a direct, wholly owned subsidiary of SWG Holdings, and the Company no longer holds the assets related to Southwest’s construction segment. Following this distribution, in accordance with the Plan of Reorganization, SWG Holdings immediately contributed its membership interests in Southwest Gas, LLC to Utility Group, thereby establishing Utility Group as the sole member and managing member of Southwest Gas, LLC, an indirect, wholly owned subsidiary of SWG Holdings.

Accordingly, SWG Holdings became a sponsor of the Assumed Plans, and each award under an Assumed Plan outstanding immediately prior to the Merger that was eligible to be paid or settled in Company Common Stock will, to the extent such award meets all the applicable requirements for payment or settlement under the applicable Assumed Plan, instead be paid or settled, as applicable, in SWG Holdings Common Stock, and, with respect to each such award, all references to “Company” in the applicable Assumed Plan, and in any agreement evidencing such award, if any, will refer to SWG Holdings. In addition, the same number of ~~shares of SWG Holdings Common Stock has been reserved for purposes of~~ the ~~Assumed~~Securities ~~Plans~~Exchange ~~and~~Act ~~is equal to the number~~ of ~~shares of Company Common Stock reserved as of the Merger.

In accordance with Rule 414 under the Securities Act, SWG Holdings will file post-effective amendments to the related registration statements on ~~Form S-8~~its ofbehalf ~~the Company (File Nos. 333-200835, 333-185354,~~by ~~333-168731, 333-155581, 333-215145 and 333-215150) (collectively,~~ the ~~“Form S-8~~undersigned ~~Registration~~hereunto ~~Statements”)~~duly ~~to adopt the Form S-8 Registration Statements pursuant to Rule 414~~authorized.

The foregoing description of the Plan of Reorganization, the Merger Agreement, the Management Incentive Plan, the 2006 Restricted Stock/Unit Plan, the Employees’ Investment Plan and the Change in Control Agreements does not purport to be complete and is qualified in its entirety by reference to the full text of the foregoing documents, which are filed as Exhibit 2.1, Exhibit 2.2, Exhibit 10.1, Exhibit 10.2, Exhibit 10.3 and Exhibit 10.4 (form of), respectively, and incorporated by reference herein.

As previously noted, upon consummation of the Merger, each share of Company Common Stock issued and outstanding immediately prior to the Merger automatically converted into an equivalent corresponding share of SWG Holdings Common Stock having the same designations, rights, powers and preferences and the same qualifications, limitations and restrictions as the corresponding share of Company Common Stock that was converted.
