Atlantic Tele-Network Enters into $150 Million Credit Facility

Salem, MA (September 10, 2008) – Atlantic Tele-Network, Inc. (NASDAQ: ATNI) today reported that it has entered into a new $150 million senior secured credit facility. The credit facility consists of a $75 million term loan and a $75 million revolving loan and replaces the Company’s existing credit facility. CoBank, ACB acted as lead arranger in the transaction.

“The new credit facility reflects our strong balance sheet and operating performance over the last few years, and will provide us with even greater financial flexibility in managing our businesses and growth initiatives,” said Justin D. Benincasa, Chief Financial Officer of Atlantic Tele-Network, Inc.

The Company used approximately $50 million of the new term loan to repay outstanding borrowings under the Company’s prior credit facility, which was terminated. The Company expects to use the remaining proceeds from the credit facility for working capital expenses, capital expenditures, acquisitions and other general corporate purposes. The Company currently has no borrowings under the new revolving loan.

The term loan has a term of seven years, maturing on September 9, 2015. The revolving loan has a term of six years, maturing on September 9, 2014. Amounts borrowed under the credit facility bear interest, at the Company’s option, at (a) London Interbank Offered Rate (LIBOR) plus applicable margin ranging from 1.25% to 2.00% or (b) Base rate (prime rate) plus applicable margin ranging from 0% to 0.5%. As with the prior credit facility, the Company’s obligations under the new credit facility are guaranteed by certain of its domestic subsidiaries, including its principal domestic operating subsidiaries; and the Company’s obligations are secured by a first priority lien on substantially all of the property and assets of the Company and certain of its domestic subsidiaries and by a pledge of the capital stock owned by the Company in certain of its foreign and domestic subsidiaries. The credit facility also provides that the

Company and any of the lenders may agree to enter into an additional term loan of up to $50 million.
