Item 1.01. Entry into a Material Definitive Agreement
Item 3.02. Unregistered Sales of Equity Securities

On April 14,  2006,  Level 3  Communications,  LLC  ("Level 3  Communications"),
entered  into a purchase  agreement  (the  "Purchase  Agreement")  with MCCC ICG
Holdings,  LLC  ("MCCC")  and solely for  purposes  of certain  portions  of the
Purchase Agreement, Level 3 Communications,  Inc. ("Level 3"), pursuant to which
Level  3  Communications  would  purchase  from  MCCC  all of the  stock  of ICG
Communications, Inc., a privately held Colorado-based telecommunications company
("ICG").

Under the terms of the Purchase Agreement, Level 3 Communications expects to pay
total consideration of $163 million,  consisting of $127 million in unregistered
shares of Level 3 common stock and $36 million in cash,  subject to  adjustments
based on  working  capital  and other  matters.  The number of shares of Level 3
common stock to be delivered  will be  determined by the result of dividing $127
million by the average of the  volume-weighted  sales price per share of Level 3
common  stock for the seven  consecutive  trading  days on the  Nasdaq  National
Market ending the second  business day  immediately  preceding the closing date.
The Purchase  Agreement also gives Level 3  Communications  a cash  substitution
right that allows it to pay additional cash  consideration  instead of shares of
Level 3 common stock.

The  transaction  does not include ICG's  investments  in New Global  Telecom or
Mpower  Holding  Corporation.  Closing is expected to occur mid-year 2006 and is
subject to customary closing  conditions,  including receipt of applicable state
and federal  regulatory  approvals.  The Purchase  Agreement  contains customary
representations, warranties, covenants and indemnities.

The shares of Level 3 common stock issued, if any, will be sold to MCCC pursuant
to the exemption from  registration  contained in Section 4(2) of the Securities
Act of 1933, as amended.

MCCC under the Purchase Agreement. The Level 3 common stock will also be subject
to a transfer  restriction  that  limits  the  number of shares  MCCC and Seller
Owners can sell  (with  certain  exceptions)  on any given  day.  This  transfer
restriction  expires  180  days  from  the  effective  date of the  registration
statement (the  "Effective  Date").  In addition,  pursuant to the  Registration
Rights Agreement (with certain exceptions),  (i) at any time after the Effective
Date (with certain exceptions),  MCCC and Seller Owners shall not, and shall not
permit any of their  affiliates  to  knowingly  make any direct  transfer of the
Level 3 common  stock in a  negotiated  transaction  to one or more persons that
would result in the acquirer  holding  economic or voting ownership in excess of
five percent (5%) or more of the Level 3 common stock and (ii) at any time after
the Effective Date and prior to June 30, 2006,  MCCC and the Seller Owners shall

3 common stock.
