BROOMFIELD,  Colo., April 17, 2006 - Level 3 Communications,  Inc. (Nasdaq:LVLT)
today announced that it has signed a definitive  agreement to acquire all of the
stock  of  ICG   Communications,   Inc.,   a   privately   held   Colorado-based

consideration of $163 million, consisting of $127 million in unregistered shares
of Level 3 common  stock and $36  million  in cash.  The  number of shares to be
delivered will be determined immediately prior to closing.

ICG primarily provides transport, IP and voice services to wireline and wireless

over 2,000 metro and  regional  fiber miles in  Colorado  and Ohio and  includes
approximately 500 points of presence. ICG serves more than 1,600 customers.

"ICG is a well-run  business with a strong and growing base of customers,"  said
Kevin  O'Hara,   president  and  chief  operating  officer  of  Level  3.  "This
transaction  gives Level 3 the  opportunity to further expand our footprint into
areas where we see demand for our services, and to realize cost savings."




"Level 3 has an excellent  reputation in the communications  industry," said Dan
Caruso, president and chief executive officer of ICG Communications. "We believe
our customers and employees  will be in good hands.  ICG and its customers  will
benefit  greatly from access to Level 3's expansive  network and its broad suite
of communications services. We look forward to working with the Level 3 team."

"ICG  standalone  is expected to  generate  approximately  $75 to $80 million of
annualized  revenue and approximately $10 to $15 million of annualized  positive
cash flow after  approximately $10 million in capital  expenditures," said Sunit
S.  Patel,  chief  financial  officer  of  Level 3  Communications.  "We  expect
annualized cash flow to improve to approximately $30 to $40 million once we have
completed integration, which is expected to begin later this year."

The purchase price is subject to certain customary working capital  adjustments.
Level 3 has the right to  substitute  cash in lieu of  delivering  shares of its
common stock. The transaction  does not include ICG's  investments in New Global
