Global Crossing Closes Term Loan Facility

Original Facility Upsized to $350 Million, for Net Cash Proceeds of $337 Million

Florham Park, N.J.—June 4, 2007 — Global Crossing (NASDAQ: GLBC), a leading global IP solutions provider, announced that it amended its five-year, senior secured term loan facility to increase the amount of the term loan facility from $250 million to $350 million, yielding total net cash proceeds estimated at $337 million after payment of fees and expenses. The facility was increased in light of strong demand in syndication of the facility by joint book runners Goldman Sachs and Credit Suisse.

The term loan facility bears interest at LIBOR plus 6.25 percent; has financial maintenance and other covenants; and has a call premium of 3 percent in the first year, 2 percent in the second year and 1 percent in the third year of the facility. The facility is secured by substantially all of Global Crossing’s worldwide assets excluding GCUK and Global Crossing’s Latin American assets (including Impsat).

In connection with the establishment of the term loan facility, the company’s majority shareowner, ST Telemedia, agreed to subordinate their mandatorily convertible notes to the term loans, and, subject to certain conditions, to convert the notes no later than September 6, 2007. ST Telemedia is receiving $7.5 million in cash upfront, plus common stock and warrants totaling 16.58 million shares upon conversion.
