The Reporting Persons may at any time amend, pursue, or choose not to pursue the Proposed Transaction; change the terms of the Proposed Transaction, including the price or the conditions of the Proposed Transaction; or take action to facilitate or increase the likelihood of consummation of the Proposed Transaction.
The Proposed Transaction would result in one or more of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D, including an extraordinary corporate transaction involving the Issuer, a change in the present board of directors or management of the Issuer, the termination of the registration of the Shares under the Securities Act of 1934, and the delisting of a class of securities of the Issuer from the New York Stock Exchange. The Reporting Persons may, at any time and from time to time, formulate other plans or proposals regarding the Issuer and the Shares, or any other actions that could involve one or more of the types of transactions or have one or more of the results described in paragraphs (a) through (j) of Item 4 of Schedule 13D.
In connection with the submission of the June Offer Letter to the Issuer, the Reporting Persons issued the Press Release attached hereto as Exhibit (a)(5)(U), which is incorporated herein by reference.
