A special meeting of the shareholders (the “Special Meeting”) of Premiere Global Services, Inc. (the “Company”) was held on December 3, 2015. A total of 34,718,533 shares, or approximately 74.3% of the common stock issued and outstanding as of the record date of October 22, 2015, was represented at the Special Meeting in person or by proxy, which constituted a quorum. A summary of the voting results for each of the following proposals, each of which is described in detail in the Company’s proxy statement dated October 26, 2015, which was first mailed to the Company’s shareholders on or about October 27, 2015, is set forth below:

The Company’s shareholders approved the Agreement and Plan of Merger, dated as of September 10, 2015 (the “Merger Agreement”), by and among the Company, Pangea Private Holdings II, LLC, a Delaware limited liability company (“Parent”), and Pangea Merger Sub Inc., a Georgia corporation and a wholly owned subsidiary of Parent (“Merger Sub”), pursuant to which Merger Sub will merge with and into the Company, and the Company will become a direct wholly owned subsidiary of Parent. The following are the tabulated votes “For” and “Against” this proposal, as well as the number of “Abstentions” and “Broker Non-Votes”:

Because a quorum was present at the Special Meeting and there were sufficient votes at the time of the Special Meeting to approve the Merger Agreement, the vote on the proposal to approve the adjournment of the Special Meeting if necessary to solicit additional proxies if there had not been sufficient votes to approve the Merger Agreement was not called.

The Company’s shareholders, on a non-binding, advisory basis, approved the compensation that will or may become payable by the Company to its named executive officers in connection with the merger. The following are the tabulated votes “For” and “Against” this proposal, as well as the number of “Abstentions” and “Broker Non-Votes”:

On December 3, 2015, the Company issued a press release announcing the results of the Special Meeting. A copy of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and incorporated herein by reference.
