Item 5.  Other Events.

     On February 23, 2000, Newbridge Networks Corporation and Alcatel issued a
joint press release announcing that they have entered into a Merger Agreement by
which Alcatel will acquire all of the currently issued and outstanding common
shares of Newbridge pursuant to a Plan of Arrangement under section 192 of the
Canada Business Corporations Act.

     Pursuant to the Plan of Arrangement, the authorized share capital of
Newbridge will be reorganized by creating a new class of shares to be designated
as Exchangeable Shares. Holders of common shares of Newbridge will receive 0.81
Exchangeable Shares (the "Exchange Ratio") for each common share of Newbridge
held. At the option of the shareholder, as part of the Plan of Arrangement each
Exchangeable Share resulting from the change of Newbridge common shares into
Exchangeable Shares may be retained by the holder or else each Exchangeable
Share will be simultaneously exchanged for one American Depositary Share (ADS)
of Alcatel. Thereafter, each Exchangeable Share will be exchangeable at any time
at the option of the holder, and, in certain circumstances, at the option of
Alcatel Holdings, for one Alcatel ADS. The Exchangeable Shares will entitle
holders to dividend and other rights that are economically equivalent in all
material respects to those of holders of Alcatel ADSs. The Exchangeable Shares
will not carry voting rights and the holders thereof will not be entitled to
receive notice of or attend any meeting of the shareholders of Newbridge (except
as required by applicable law) or of Alcatel.

     Newbridge shareholders who elect to receive Alcatel ADSs will be entitled
to vote and to receive notice of and to attend meetings of the shareholders of
Alcatel.

     Each Newbridge option granted under any of the Newbridge stock option plans
will be replaced with an option to acquire the number of Alcatel ADSs equal to
the Exchange Ratio multiplied by the number of common shares of Newbridge that
may be purchased as if such original Newbridge option were exercisable and
exercised immediately prior to the effective date of the Plan of Arrangement.
The exercise price for each Alcatel ADS will equal the exercise price of the
original Newbridge option, divided by the Exchange Ratio. The vesting period for
certain Newbridge options will be accelerated, as described in the Merger
Agreement. In addition, each Newbridge warrant outstanding on the effective date
of the Plan of Arrangement will be amended to provide for the right to purchase
the number of Exchangeable Shares equal to the product of the Exchange Ratio
multiplied by the number of common shares of Newbridge that may be purchased as
if such Newbridge warrants were exercisable and exercised immediately prior to
the effective date of the Plan of Arrangement. The exercise price for each
amended warrant will equal the exercise price of the original Newbridge warrant,
divided by the Exchange Ratio.

     As of the date of the Merger Agreement, an Alcatel ADS represents one-fifth
(1/5/th/) of an ordinary share of the capital stock of Alcatel. Alcatel arranges
for the issuance of American Depositary Receipts (ADRs) to evidence the Alcatel
ADSs.

     The Plan of Arrangement must be approved by at least two-thirds of the
votes cast at a special meeting of Newbridge's shareholders (which will include
holders of Newbridge common shares, options and warrants).  The completion of
the Plan of Arrangement is conditional upon, among other things, obtaining
Newbridge and Alcatel shareholder approval,

                                      -2-


court approval, certain regulatory approvals, conditional listing approval from
The Toronto Stock Exchange of the Exchangeable Shares and New York Stock
Exchange approval of the listing of Alcatel ADSs to be issued on the effective
date of the Plan of Arrangement and the Alcatel ADSs to be provided upon the
exchange of the Exchangeable Shares. In addition, Alcatel is not obligated to
complete the Plan of Arrangement if, among other things, holders of more than 5%
of the common shares of Newbridge have exercised their dissent rights (as
described in the Merger Agreement) or if the transactions contemplated in the
Plan of Arrangement cannot be accounted for as a pooling-of-interests under
French generally accepted accounting principles. Also, unless otherwise agreed
in writing between the parties, the Merger Agreement will be terminated if the
effective date of the Plan of Arrangement does not occur on or prior to
September 30, 2000, subject to either party being entitled to unilaterally
extend such date to December 31, 2000 in certain circumstances relating to
obtaining regulatory approvals.

     Pursuant to an Option Agreement dated February 22, 2000, Newbridge also
granted to Alcatel an option to purchase up to 36,183,000 common shares of
Newbridge at the final reported price on the TSE on February 22, 2000, being
Cdn. $50.60. The option is exercisable in limited circumstances where the break
fee agreed to be paid to Alcatel by Newbridge under the Merger Agreement becomes
payable. The value of the option together with the break fee is capped at Cdn.
$375 million and Alcatel has the option to elect to receive the cash value of
the option rather than common shares of Newbridge.

     Pursuant to the terms of a Voting Agreement entered into among Dr. Terence
Matthews, certain holding companies of Dr. Matthews and Alcatel, dated February
22, 2000, Dr. Matthews has agreed, among other things, not to negotiate with,
solicit, initiate or encourage submission of proposals or offers from, or
provide information to, any other person, entity or group relating to an
Acquisition Proposal. Dr. Matthews has further agreed to vote or cause to be
voted all of the common shares of Newbridge owned directly or indirectly by him
or over which he holds voting or dispositive power in favor of the approval of
the transactions contemplated in the Plan of Arrangement and against any action
that would impede, interfere or discourage the completion of the Plan of
Arrangement. Dr. Matthews is Chairman of the Board of Directors and Chief
Executive Officer of Newbridge.
