reference into this Item&nbsp;4), the purpose of the transactions described in this Statement was for the Buyer, through Merger Sub, to acquire control of, and the entire equity interest in, the Company. The Offer, as the first step in the
acquisition of the Company, was intended to facilitate the acquisition of all outstanding Shares. The purpose of the Merger was to acquire all of the outstanding Shares not tendered and purchased pursuant to the Offer. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">On December&nbsp;9, 2011, Merger Sub commenced the Offer upon the terms and subject to the conditions set forth in the Offer to Purchase,
as amended, and in the related Letter of Transmittal. The Offer expired at 12:00 midnight, Eastern Standard Time, at the end of Monday, January&nbsp;9, 2012. BNY Mellon Shareowner Services, the depositary for the tender offer, indicated that it
estimated as of 12:00 midnight on January&nbsp;9, 2012, a total of 42,861,222 Shares had been validly tendered and not withdrawn pursuant to the tender offer during the offering period (including 5,096,232 Shares delivered pursuant to the guaranteed
delivery procedures). On January&nbsp;12, 2012, 1,002,616 Shares tendered under guaranteed delivery instructions were not delivered. As such, Purchaser had accepted for payment a total of 41,858,606 Shares, representing approximately 92.74% of the
Issuer&#146;s outstanding Shares at the Effective Time (as defined below). Merger Sub accepted all tendered Shares for payment pursuant to the terms of the Offer (the &#147;<U>Acceptance</U>&#148;) and will promptly pay for such Shares. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">The Merger Agreement provided that upon acceptance by Merger Sub of any Shares for payment pursuant to the Offer, and from time to time
thereafter as Shares were accepted for payment and paid for by Merger Sub, the Buyer would be entitled to designate a majority of the board of directors of the Company (the &#147;<U>Board</U>&#148;) and all committees of the Board. The exact number
of directors that the Buyer could designate was in proportion to the percentage of Shares that the Buyer then held, and was rounded up to the nearest whole number. </FONT></P>

received and verified by the depositary that the top-up option shares were ultimately not required to enable the merger to be effected. The Buyer then effected a short-form merger in which Merger Sub merged with and into the Company with the Company
