Orange to redeem $1,215,000,000 in 4.375% Notes due 2014

Orange announces its intention to redeem $1,215,000,000.00 aggregate principal amount of 4.375% Notes due July 2014, which represents all of the remaining principal amount outstanding. Notice will be sent to holders in due course as provided in the Indenture dated as of July 9, 2009 (as amended and supplemented) between France Telecom, which changed its name to Orange as of July 1, 2013, and The Bank of New York Mellon, as trustee.

The Notes are expected to be redeemed on or about March 11, 2014 at a redemption price to be equal to the greater of (i) 100% of the principal amount of the Notes, and (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon (excluding interest accrued to the date of redemption) discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the Treasury Rate (as defined in the Notes) plus 0.30% per annum for the Notes to be redeemed. Orange will also pay accrued interest on the principal amount of the Notes being redeemed up to, but not including, the date of redemption.
