LONDON - Global Crossing (UK) Finance Plc (”GCUK Finance”), a wholly owned subsidiary of Global Crossing (Nasdaq: GLBC), today announced that it has completed the annual excess cash offer for its 11.75 percent Sterling-denominated and 10.75 percent Dollar-denominated senior secured notes due in 2014.

In accordance with the indenture governing its notes, GCUK Finance offered to purchase for cash up to 7.766 million British pounds sterling in aggregate principal amount, including accrued and unpaid interest (the “Excess Cash”), of its 10.75-percent U.S. dollar-denominated senior secured notes due in 2014 and its 11.75-percent British pounds sterling-denominated senior secured notes due in 2014. The notes are guaranteed by Global Crossing (UK) Telecommunications Limited (”GCUK”), GCUK Finance’s immediate parent and the principal UK operating subsidiary of Global Crossing.

GCUK Finance reported that holders tendered notes with aggregate principal amount, including accrued and unpaid interest, in excess of 7.766 million British pounds sterling. GCUK accepted the offer at 5:00 p.m. BST on May 26, 2009.

Notes that were properly tendered and accepted for purchase in accordance with the terms and conditions of the offer document were accepted for purchase on a pro rata basis among tendering note holders based upon the amounts tendered, as the aggregate principal amount of notes tendered exceeded the amount that could be purchased using the Excess Cash at a purchase price of 100 percent of the principal amount thereof plus accrued interest. For the purposes of determining the aggregate principal amount of the notes tendered in order to apply the pro rata calculation, the aggregate principal amount of the sterling-denominated notes tendered was converted to dollars at the noon buying rate in the City of New York for cable transfers in pounds sterling as announced by the Federal Reserve Bank of New York for customs purposes on April 24, 2009. Notes accepted for purchase were purchased at a cash price equal to 100 percent of the outstanding principal amount of the notes tendered, together with any accrued and unpaid interest outstanding on the date of the purchase.
