LONDON, April 12, 2010 - Global Crossing (UK) Finance plc ("GCUK Finance"), a wholly owned
subsidiary of Global Crossing (Nasdaq: GLBC), announced today that it has
begun an excess cash offer with respect to its senior secured notes.

In accordance with the indenture governing its notes, GCUK Finance will
offer to purchase for cash up to 12.593 million British pounds sterling in
aggregate principal amount, including accrued 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 pound 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.

The offer is being made pursuant to the terms of the indenture governing
the senior secured notes. The indenture requires GCUK Finance to make an
offer to purchase the maximum principal amount of the senior secured notes
possible using 50 percent of GCUK's excess operating cash flow for the period
from December 23, 2004 to December 31, 2005 and for each twelve-month period
thereafter.

The excess cash offer will expire at 4:00 p.m. London time on May 11,
2010, unless extended. The terms and conditions of the offer are described in
GCUK Finance's offer document dated April 6, 2010.

Notes that are properly tendered and accepted for purchase in accordance
with the terms and conditions of the offer document will be 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. If the aggregate principal amount of notes tendered
exceeds the amount that can be purchased using the Excess Cash at a purchase
price of 100 percent of the principal amount thereof plus accrued interest,
notes will be accepted for purchase on a pro rata basis among tendering note
holders based upon the amounts tendered. For 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 will be 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 9, 2010.

Tenders may be validly withdrawn until 10:00 a.m. London time on May 14,
2010 or, if the offer period is extended, at 10:00 a.m. London time three
business days after the expiration date for the offer.
