Discussions to Re-Price and Amend the Existing Credit Agreement

On April 2, 2013, Telesat Holdings Inc. (“Telesat”) announced the execution of its previously announced amendment (the “Amendment”) to its existing credit agreement, dated March 28, 2012 (the “Credit Agreement”), among its wholly-owned subsidiaries, Telesat Canada and Telesat LLC, as borrowers (the “Borrowers”), JP Morgan Chase Bank, N.A., as administrative agent, and the other financial institutions party thereto.

The Amendment effectively re-prices the Borrowers’ Term Loan B facility under the Credit Agreement, converts a portion of the Term Loan B facility from Canadian Dollars to U.S. Dollars, allows the Borrowers to incur additional debt under the Credit Agreement or otherwise if the first lien leverage ratio is less than or equal to 4.25:1.00 (which represents a change from the 4:00:1.00 senior secured leverage ratio in the Credit Agreement) and makes certain other changes.

The Borrowers have received the lender consents required under the Credit Agreement in connection with the execution of the Amendment. Giving effect to the Amendment, the Borrowers have approximately US$1,746 million and approximately CND$140 million outstanding under the Term Loan B facilities.

The foregoing description of the Amendment does not purport to be complete and is qualified in its entirety by reference to the Amendment, attached as Exhibit 4.1 to this report of foreign private issuer on Form 6-K and incorporated herein by reference. Telesat’s press release, dated April 2, 2013, announcing the execution of the Amendment, is attached as Exhibit 99.1 hereto.
