Election Proposal

The Election Proposal set forth in the Consent Statement requests your consent to elect four Nominees to serve on the Sun-Times Board, Jeremy L. Halbreich, Robert A. Schmitz, Lee S. Hillman, and Michael E. Katzenstein.

On December 5, 2008, Lee S. Hillman informed us of his decision to withdraw as a nominee to be a director of Sun-Times due to business and personal time constraints. We are continuing our solicitation of your consent to elect the other Nominees (Messrs. Halbreich, Schmitz and Katzenstein) pursuant to the Election Proposal to fill the vacancies created by the removal of the current members of the Sun-Times Board (other than Robert B. Poile) pursuant to the Removal Proposal. Accordingly, the following is now the text of the Election Proposal:

“To elect each of the following three (3) individuals to serve as a director of Sun-Times Media Group, Inc. (or, if any such nominee is unable or unwilling to serve as a director of Sun-Times Media Group, Inc., any other person designated as a nominee by the remaining nominee or nominees):

(01) Jeremy L. Halbreich

(02) Robert A. Schmitz

(03) Michael E. Katzenstein”

If elected to serve on the Sun-Times Board, the other Nominees as members of a reconstituted Sun-Times Board with Robert B. Poile would intend to designate an individual to fill the vacancy created by Mr. Hillman’s withdrawal from consideration. The reconstituted Sun-Times Board would consider qualified candidates, including those from the Chicago area, whom it believes can provide significant contributions to the future of Sun-Times.

It is our view that a reconstituted Sun-Times Board, consisting of Jeremy L. Halbreich, Robert A. Schmitz and Michael E. Katzenstein, along with current director Robert B. Poile, and an additional candidate to be selected by the reconstituted Board, will be committed to safeguarding and promoting the best interests of all Sun-Times stockholders.

Any consent cards already submitted to us consenting to the election of Nominees including Mr. Hillman will be treated as consent to all Nominees (other than Mr. Hillman).

We urge you to consent to the Bylaw Restoration Proposal, the Removal Proposal and the Election Proposal by signing, dating and returning the WHITE consent card in the postage-paid envelope provided. Please note that you must sign AND date your consent card in order for it to be valid. We urge you not to revoke your consent by signing any blue consent revocation card sent to you by Sun-Times or otherwise, and to revoke any consent revocation you may have already submitted to Sun-Times.
