A special meeting of shareholders of Belo Corp. (“Belo”) was held on September 25, 2013. The special meeting was held to vote upon the following proposals set forth in Belo’s definitive proxy statement, filed with the U.S. Securities and Exchange Commission (the “SEC”) on August 21, 2013: (1) to approve the Agreement and Plan of Merger (the “Merger Agreement”), dated as of June 12, 2013, by and among Belo, Gannett Co., Inc., and Delta Acquisition Corp. (“Merger Sub”), pursuant to which Belo will merge (the “Merger”) with and into Merger Sub (the “Merger Proposal”); (2) to approve, on an advisory (non-binding) basis, specified compensation that may be payable to the named executive officers of Belo in connection with the Merger (the “Advisory Compensation Proposal”); and (3) to adjourn the Belo special meeting, if necessary or appropriate, to solicit additional proxies in favor of the Merger Proposal (the “Adjournment Proposal”).

At the special meeting, the Merger Proposal was approved by the affirmative vote of more than two-thirds of the voting power of all outstanding Belo common stock entitled to vote at the special meeting. In addition, the Advisory Compensation Proposal was approved by a majority of the votes cast at the special meeting. Sufficient votes were also received to approve the Adjournment Proposal, but an adjournment was not necessary in light of the approval of the Merger Proposal.
