Item 1.01.   Entry into a Material Definitive Agreement.

On October 16, 2006, Level 3 Communications, Inc. ("Level 3") entered into an
Agreement and Plan of Merger (the "Merger Agreement") by and among Level 3,
Level 3 Services, LLC and Level 3 Colorado, Inc., each a wholly owned subsidiary
of Level 3, and Broadwing Corporation, a Delaware corporation ("Broadwing"),
pursuant to which Broadwing will be merged with and into a wholly owned
subsidiary of Level 3(the "Merger") on the terms and subject to the conditions
of the Merger Agreement, with the Level 3 subsidiary continuing as the surviving
entity.

Under the terms of the Merger Agreement, each share of Broadwing's common stock
outstanding immediately prior to the Merger (except for shares for which
appraisal rights are exercised) will be converted into $8.18 of cash and 1.3411
shares of Level 3 common stock. Level 3 expects to pay approximately $744
million of cash and issue 122 million shares of its common stock in the Merger.

Closing of the Merger is subject to customary conditions, including approval of
the Merger by a majority of Broadwing's common shares entitled to vote thereon,
receipt of applicable regulatory approvals, the effectiveness of a registration
statement on Form S-4 in connection with the registration under the Securities
Act of 1933, as amended, of the Level 3 common stock to be issued in the merger,
no material adverse change in the business or condition of Broadwing prior to
the effective time of the Merger and holders of less than ten percent (10%) of
Broadwing's outstanding common stock exercising appraisal or dissenter's rights.

In connection with the Merger Agreement, Dr. David R. Huber, the Chairman of the
Board of Directors of Broadwing, and certain entities related to Dr. Huber who
in the aggregate hold shares of Broadwing common stock representing
approximately 8.9% of the outstanding common stock of Broadwing, have executed a
voting agreement which, subject to limited exceptions, requires such
stockholders to vote their Broadwing shares in favor of the Merger.

The Merger Agreement contains customary representations, warranties and
covenants for a transaction of this type regarding, among other things,
Broadwing's corporate organization and capitalization, the accuracy of its
reports and financial statements filed under the Securities Exchange Act of
1934, as amended (the "Exchange Act"), the absence of certain changes or events
relative to Broadwing since December 31, 2005, and Broadwing's receipt of
fairness opinions regarding the Merger from its financial advisors. Similarly,
Level 3 makes representations and warranties regarding, among other things, its
corporate organization and capitalization and the accuracy of its reports and
financial statements filed under the Exchange Act.

The Merger Agreement also includes covenants governing, among other things,
Broadwing's operations outside the ordinary course of business prior to the
closing of the Merger. In addition, the Merger Agreement contains certain
termination rights allowing Broadwing, Level 3 or both parties to terminate the
agreement upon the occurrence of certain conditions, including the failure to
consummate the Merger by October 16, 2007.

A copy of the Merger Agreement is attached as Exhibit 10.1 and a copy of the
form of Voting Agreement is attached as Exhibit 10.2 and each of them are
incorporated herein by reference. The foregoing description of the Merger
Agreement and Voting Agreement is qualified in its entirety by reference to the
full text of the Merger Agreement and Voting Agreement. The Merger Agreement has
been included to provide investors with information regarding its terms. Except
for its status as the contractual document that establishes and governs the
legal relations among the parties thereto with respect to the transactions
described above, the Merger Agreement is not intended to be a source of factual,
business or operational information about the parties.


As described above, the Merger Agreement contains representations and warranties
that Level 3 and Broadwing made to each other as of the date of the Merger
Agreement or other specific dates, and such representations and warranties
should not be relied upon by any other person. The assertions embodied in those
representations and warranties were made solely for purposes of the contract
between Level 3 and Broadwing and are subject to important qualifications and
limitations agreed to by Level 3 and Broadwing in connection with negotiating
the Merger Agreement. Accordingly, you should not rely on the representations
and warranties as accurate or complete or characterizations of the actual state
of facts as of any specified date since they are modified in important part by
the underlying disclosure schedules which are not filed publicly and which are
subject to a contractual standard of materiality different from that generally
applicable to stockholders and were used for the purpose of allocating risk
between Level 3 and Broadwing rather than establishing matters as facts.

Item 7.01.  Regulation FD Disclosure.

On October 17, 2006, Level 3 issued a press release announcing that it has
signed a Merger Agreement to acquire Broadwing. This press release is furnished
as Exhibit 99.1 to this Form 8-K and incorporated by reference as if set forth
in full. The furnishing of this information shall not be deemed an admission as
to the materiality of the information included in this Form 8-K. This
information is not filed but is furnished to the Securities and Exchange
Commission (the "SEC") pursuant to Item 7.01 of Form 8-K.

This document shall not constitute an offer of any securities for sale. The
proposed transaction will be submitted to Broadwing's stockholders for their
consideration. Level 3 and Broadwing will file a registration statement, a proxy
statement/prospectus and other relevant documents concerning the proposed
transaction with the SEC. Stockholders of Broadwing are urged to read the
registration statement and the proxy statement/prospectus and any other relevant
documents filed with the SEC when they become available, as well as any
amendments or supplements to those documents, because they will contain
important information. Stockholders of Level 3 can obtain more information about
the proposed transaction by reviewing the Form 8-K to be filed by Level 3 in
connection with the announcement of the transaction, and any other relevant
documents filed with the SEC when they become available. You will be able to
obtain a free copy of the proxy statement/prospectus, as well as other filings
containing information about Level 3 and Broadwing, at the SEC's Web site
(http://www.sec.gov). Copies of the proxy statement/prospectus and the SEC
filings that will be incorporated by reference in the proxy statement/prospectus
can be obtained, without charge, by directing a request to Level 3, Investor
Relations, 1025 Eldorado Blvd., Broomfield, CO 80021, 720-888-2500 or to
Broadwing, Investor Relations, 1122 Capital of Texas Highway South Austin, TX
78746-6426, (866) 426-7847.

Level 3, Broadwing and their respective directors and executive officers may be
deemed to be participants in the solicitation of proxies from the stockholders
of Broadwing in connection with the proposed transaction. Information about the
directors and executive officers of Level 3 is set forth in the proxy statement
on Schedule 14A, dated April 6, 2006, as supplemented, for Level 3's 2006 annual
meeting of stockholders. Information about directors and executive officers of
Broadwing and their ownership of Broadwing common stock is set forth in the
proxy statement on Schedule 14A, filed with the SEC on March 24, 2006, for
Broadwing's 2006 annual meeting of stockholders. Additional information
regarding participants in the proxy solicitation may be obtained by reading the
proxy statement/prospectus regarding the proposed transaction when it becomes
available.
