                                                               February 22, 2000

TO:  ALCATEL

Dear Sirs,

     Re:  Plan of Arrangement involving NEWBRIDGE CORPORATION

     In consideration of ALCATEL ("ALCATEL") entering into a merger agreement
dated the date hereof with, and agreeing to participate in the plan of
arrangement involving, NEWBRIDGE NETWORKS CORPORATION ("NEWBRIDGE") (the
"Transaction"), this letter agreement sets out the terms on which Terence
Matthews and his associated corporations referred to herein (each, a
"Shareholder" and collectively, the "Shareholders") undertake to take certain
actions and do certain things in respect of the Transaction.

     The terms of the Transaction are summarized in the Merger Agreement dated
February 22, 2000 between ALCATEL and NEWBRIDGE (the "Merger Agreement"), and
capitalized terms used herein and not otherwise defined shall have the meanings
set forth in the Merger Agreement.

1.   Each of the Shareholders hereby represents and warrants to you (and
     acknowledges that you are relying upon such representations and
     warranties):

     (a)  that the common shares in the capital of NEWBRIDGE and the options to
          acquire the common shares in the capital of NEWBRIDGE (the "Shares"
          and the "Options", respectively) set forth on Annex I include all
                                                        -------
          Shares and Options held of record, owned by, or for which voting or
          dispositive power is granted to, any relative, trust or other
          affiliate of Shareholder of which Shareholder has or shares any voting
          power or power of disposition.  Except as described on Schedule 1(a),
                                                                 -------------
          Shareholder is the record and beneficial owner, has sole voting power,
          sole power of disposition and sole power to agree to all of the
          matters set forth in this Agreement, in each case with respect to the
          Shares and the Options set forth on Annex I attributable to such
                                              -------
          Shareholder.  Shareholder has good and marketable title to the Shares,
          free and clear of all liens, pledges, mortgages and encumbrances,
          except as set forth on Schedule 1(a) hereto.  As to any Shares that
                                 -------------
          Shareholder indicates he/it does not have such sole powers, the
          Shareholders shall use their reasonable best efforts to cause all of
          his/its obligations under this Agreement to be complied with by any
          person having such powers.  Other than the Shares and Options set
          forth on Annex I no common
                   -------


                                      -2-


          shares or securities of NEWBRIDGE are beneficially owned or controlled
          directly or indirectly by any Shareholder;

     (b)  that Shareholder has the legal capacity to execute and deliver this
          Agreement and to consummate the transactions contemplated hereby.
          This Agreement has been duly executed and delivered by Shareholder,
          and, assuming the due authorization, execution and delivery by
          ALCATEL, this Agreement constitutes the legal, valid and binding
          obligation of Shareholder, enforceable in accordance with its terms;

     (c)  neither the execution and delivery of this Agreement by Shareholder,
          the consummation by Shareholder of the transactions contemplated
          hereby nor the compliance by Shareholder with any of the provisions
          hereof shall (i) result in any breach of, or constitute a default (or
          an event which with notice or lapse of time or both would become a
          default) (or give rise to any third party right of termination,
          cancellation, material modification or acceleration) under any of the
          terms, conditions or provisions of any note, loan agreement, bond,
          mortgage, indenture, contract, license, agreement, lease, permit or
          other instrument or obligation to which Shareholder is a party or by
          which Shareholder or any of his/its properties or assets (including
          the Shares and the Options) may be bound, except as may be set forth
          in existing option agreements, (ii) require on the part of Shareholder
          any filing with, or permit, authorization, consent or approval of, any
          Governmental Entity, or (iii) violate any order, writ, injunction,
          decree, judgment, or Law applicable to Shareholder or any of his/its
          properties or assets, excluding from the foregoing such violations,
          breaches, defaults or failures to make any filing or to obtain any
          permit, authorization, consent or approval which would not,
          individually or in the aggregate, impair the ability of Shareholder to
          consummate the transactions contemplated hereby; and

     (d)  that there is no private or governmental action, suit, proceeding,
          claim, arbitration or investigation pending before any Governmental
          Entity, or, to the knowledge of any Shareholder, threatened against
          Shareholder or any of its respective properties or any of its
          respective officers or directors, in the case of a corporate entity
          (in their capacities as such) that, individually or in the aggregate,
          could reasonably be expected to have a material adverse effect on
          Shareholder's ability to consummate the transactions contemplated by
          this Agreement. There is no judgment, decree or order against
          Shareholder or, to the knowledge of any Shareholder, any of its
          respective directors or officers, in the case of a corporate entity
          (in their capacities as such) that could prevent, enjoin, alter or
          materially delay any of the


                                      -3-

          transactions contemplated by this Agreement, or that could reasonably
          be expected to have a material adverse effect on Shareholder's ability
          to consummate the transactions contemplated by this Agreement.

2.   Each Shareholder hereby represents and warrants to you and covenants with
     you that between the date of this Agreement and the earlier of (i) the date
     of termination of the Merger Agreement in accordance with its terms, and
     (ii) the effective date of the Transaction (such earlier date being the
     "Expiry Date"), no Shareholder shall (A) sell, transfer, gift, assign,
     pledge, hypothecate, encumber or otherwise dispose of any of the Shares,
     Options or any common shares of Newbridge arising from the exercise of the
     Options (the "Additional Shares"), or enter into any agreement, arrangement
     or understanding in connection therewith, without having first obtained the
     prior written consent of ALCATEL, or (B) grant any proxies or powers of
     attorney, deposit any Shares, Options or Additional Shares (collectively,
     the "Owned Securities") into a voting trust or enter into a voting
     agreement, understanding or arrangement with respect to such Owned
     Securities; provided, however, that (I) up to a maximum of 1,000,000 Shares
     in the aggregate (less one half the number of any Shares pledged as
     described in (II)) may be sold by the Shareholders, (II) up to a maximum of
     2,000,000 Shares (less two times the number of Shares sold as described in
     (I)) may be pledged or hypocated to a bona fide lender to secure a loan (so
     long as such loan agreement provides that such Shareholder may vote such
     pledged Shares), and (III) the Owned Securities may be transferred to
     affiliates of the Shareholders to facilitate any transaction effected in
     accordance with Section 4.11 of the Merger Agreement, provided that any
                                                           -------- ----
     NEWBRIDGE shares obtained by the Shareholders in connection with such
     transaction shall be subject to the terms hereof.  None of the provisions
     of this Agreement shall apply to any of the secured parties described in
     Schedule 1(a) or who may become secured parties pursuant to this Section
     2(II) that realize on their security interest in such pledged or
     hypothecated Shares.

3.   The Shareholders hereby undertake, until the Expiry Date:

     (a)  to vote (or cause to be voted) all the Shares, the Additional Shares
          and the Options at any meeting of the shareholders of NEWBRIDGE, and
          in any action by written consent of the shareholders of NEWBRIDGE (i)
          in favour of the approval, consent, ratification and adoption of the
          Transaction (and any actions required in furtherance thereof); or (ii)
          against any action that would impede, interfere, or discourage the
          Transaction (excluding for greater certainty, a Superior Proposal),
          and against any action that would result in any breach of any
          representation, warranty or covenant in the Merger Agreement.


                                      -4-

          Upon the request or direction of ALCATEL, the Shareholders shall
          execute a proxy in respect of any such resolution, and shall have the
          Owned Securities counted or not counted as part of a quorum in
          connection with any Newbridge shareholders meeting relating to matters
          set forth in Section 3(a)(ii).

     (b)  the Shareholders shall not without the prior written consent of
          ALCATEL requisition or join in the requisition of any meeting of the
          shareholders of NEWBRIDGE for the purpose of considering any
          resolution;

     (c)  for greater certainty, in connection with any matter referred to in
          Section 3(a)(ii), the Shareholders shall consult with ALCATEL prior to
          exercising any voting rights attached to the Shares, the Additional
          Shares or the Options and shall exercise or procure the exercise of
          such voting rights as ALCATEL shall instruct, including without
          limitation the delivery to ALCATEL, upon its request or direction, of
          a proxy in respect of any such resolution; and

     (d)  each Shareholder shall use its best efforts not to default, or take or
          omit to take any action which could reasonably be expected to cause a
          default, under those loans or other arrangements to which such
          Shareholder is subject that are described in Schedule 1(a) hereto or
          as permitted pursuant to Section 2 hereof.

4.   Each Shareholder (in the case of Terence Matthews in his capacity as a
     shareholder and not as a director of NEWBRIDGE) agrees that, until the
     Expiry Date, such Shareholder will not, directly or indirectly, 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.

5.   The Shareholders hereby irrevocably agree:

     (a)  to details of this Agreement being set out in any information circular
          produced by NEWBRIDGE and/or ALCATEL in connection with the
          Transaction; and

     (b)  to this Agreement being available for inspection until the Expiry
          Date.

6.   Wesley Clover Corporation and Terence Matthews shall cause Kanata Research
     Park Corporation ("Kanata"), as soon as reasonably possible and in any
     event prior to the closing of the Transaction but conditional upon such
     closing, to have waived all of its rights to terminate any leases to which
     NEWBRIDGE or any subsidiary is a party as a result of the Transaction or


                                      -5-

     any other pre-existing conditions or liabilities whatsoever prior to the
     date hereof, and to have entered into an agreement to enable NEWBRIDGE or
     its subsidiaries at their respective option to extend such leases for up to
     two periods of up to five years each on the same terms (except as to
     renewal) and at agreed or arbitrated fair market value rents, subject only
     to applicable laws and to require NEWBRIDGE or the relevant subsidiary to
     give Kanata at least nine months notice if it does not intend to extend any
     such lease.

7.   Notwithstanding Section 3(a), the Shareholders shall not be bound to vote
     in favour of, or grant ALCATEL a proxy on the Owned Securities to vote for,
     the Transaction in the event that, at the time of the NEWBRIDGE Meeting,
     the tax laws of Canada shall have been amended, or proposed for amendment
     by the Minister of Finance, in such a manner that tax deferral for the
     Transaction would not be available via the use of exchangeable shares as is
     proposed under the Merger Agreement.

8.   I, Terence Matthews, shall cause 3090-8081 Quebec Inc. to enter into this
     Agreement as soon as practicable.

9.   I, Terence Matthews, agree and confirm that I am bound by the terms of a
     Non-Competition Agreement with NEWBRIDGE dated October 14, 1987.

10.  Any date, time or period referred to in this Agreement shall be of the
     essence except to the extent to which ALCATEL and the Shareholders agree in
     writing to vary any date, time or period, in which event the varied date,
     time or period shall be of the essence.

11.  The Shareholders agree that monetary damages would not be an adequate
     remedy for any loss incurred by reason of a breach of this Agreement by any
     of them and hereby agrees to waive the defense in any action for specific
     performance that a remedy at law would be adequate.

12.  The Shareholders agree and confirm that:

     (a)  any provision of this Agreement may be amended or waived if, and only
          if, such amendment or waiver is in writing and signed, in the case of
          an amendment, by the Shareholders and ALCATEL or in the case of a
          waiver, by the party against whom the waiver is to be effective; and

     (b)  no failure or delay by any party in exercising any right, power or
          privilege hereunder shall operate as a waiver thereof nor shall any
          single or partial exercise thereof preclude any other or further
          exercise.

13.  In consideration of the Shareholders entering into this Agreement effective
     upon the closing of the Transaction, ALCATEL shall be obligated to


                                      -6-

     reimburse the Shareholders for his/its reasonable out-of-pocket expenses,
     including legal, accounting and financial advisory fees, incurred in
     connection with the Transaction, but not in excess of CAN $200,000.

14.  The parties agree as follows:

     (a)  As soon as practicable, but in any event no later than the date upon
          which ALCATEL files with the SEC the Form F-3 pursuant to Section
          2.7(5) of the Merger Agreement, ALCATEL shall file a "shelf"
          registration statement pursuant to Rule 415 of the 1933 Act (the
          "Registration Statement"), with respect to the resale of all of the
          ALCATEL securities initially issuable upon exchange of the
          Exchangeable Shares, including, without limitation, the ALCATEL ADSs,
          to be issued to the Shareholders pursuant to the Merger Agreement
          (together with any securities of ALCATEL initially issued or issuable
          with respect to the Exchangeable Shares received by the undersigned in
          connection with the Transaction by way of a dividend or stock split or
          in connection with a combination of shares, recapitalization, merger,
          consolidation or other reorganization or otherwise, collectively, the
          "Registrable Securities"). ALCATEL shall use its reasonable efforts to
          (i) have the Registration Statement declared effective on or before
          the Effective Date, and (ii) to keep the Registration Statement
          continuously effective from the date such Registration Statement is
          declared effective until the Termination Date (as defined below).

     (b)  ALCATEL and the Shareholders shall each indemnify the other consistent
          with indemnification granted by issuers and selling shareholders for
          "shelf" registration statements.

     (c)  ALCATEL shall pay all costs, fees and expenses incident to ALCATEL's
          performance of or compliance with this Section 14, including, without
          limitation, all registration, filing, and NASD fees and all fees and
          expenses incurred in connection with compliance with state securities
          or blue sky laws (but excluding any underwriting commissions, fees or
          expenses) and with respect to any supplements or amendments to the
          Registration Statement, whether the Registration Statement becomes
          effective and whether all, none or some of the Registrable Securities
          are sold pursuant to the Registration Statement.

     (d)  The "Termination Date" means the earlier of the first date on which
          the Registrable Securities may be distributed to the public by the
          undersigned pursuant to Rule 144(k) or such date on which the


                                      -7-

          Shareholders are no longer "affiliates" of ALCATEL under the
          Securities Act and subject to Rule 145.

15.  The Shareholders, in addition to being entitled to exercise all rights
     granted by law, including recovery of damages, shall be entitled to
     specific performance of its rights under Section 14.  ALCATEL agrees that
     monetary damages would not be adequate compensation for any loss incurred
     by reason of a breach by it of the provisions of Section 14 and hereby
     agrees to waive the defense in any action for specific performance that a
     remedy at law would be adequate.

16.  The provisions of this Agreement constitute legal, valid and binding
     obligations of ALCATEL, enforceable against it in accordance with its
     terms.

17.  All notices, requests, claims, demands and other communications hereunder
     shall be in writing and shall be given (and shall be deemed to have been
     duly given upon receipt) by delivery in person, by telecopy, facsimile,
     cable, telegram or telex, or by registered or certified mail (postage
     prepaid, return receipt requested) or by a nationally recognized courier
     service to the respective parties at their addresses as specified in Annex
     II hereto.

18.  If any term or other provision of this Agreement is invalid, illegal or
     incapable of being enforced by any rule of law or public policy, all other
     conditions and provisions of this Agreement shall nevertheless remain in
     full force and effect so long as the economic or legal substance of this
     Agreement is not affected in any manner materially adverse to any party.
     Upon such determination that any term or other provision is invalid,
     illegal or incapable of being enforced, the parties hereto shall negotiate
     in good faith to modify this Agreement so as to effect the original intent
     of the parties as closely as possible in a mutually acceptable manner in
     order that the terms of this Agreement remain as originally contemplated to
     the fullest extent possible.

19.  The provisions of this Agreement shall be binding upon and enure to the
     benefit of the parties hereto and their respective successors and permitted
     assigns, provided that no party may assign, delegate or otherwise transfer
     any of its rights, interests or obligations under this Agreement without
     the prior written consent of the other parties hereto, except that ALCATEL
     may assign, delegate or otherwise transfer any of its rights, interests or
     obligations under this Agreement to an affiliate without reducing its own
     obligations hereunder without the consent of the Shareholder.

20.  This Agreement is governed by the laws of the Province of Ontario and the
     federal laws of Canada applicable therein.  All actions and proceedings
     arising out of and relating to this Agreement shall be heard and determined


                                      -8-

     exclusively in the courts of the Province of Ontario. Notwithstanding the
     foregoing, Section 15 of this Agreement shall be governed by the laws of
     the State of Delaware without regard to any applicable conflicts of law.

21.  ALCATEL shall permit NEWBRIDGE to arrange for a "safe income tuck-in"
     transaction  (the "Tuck-in") or, if a Tuck-in does not achieve the
     objective of crystallizing the "safe income" or results in other material
     adverse tax consequences to the Shareholders, another form of safe income
     crystallisation transaction, with one or more Shareholders, provided that:

     (a)  only one form of transaction will be required;

     (b)  such transaction is to be completed in accordance with applicable Laws
          prior to the Effective Date;

     (c)  such transaction (other than a Tuck-in) must be accomplished in a
          manner that does not entail any material cost, expense, obligation or
          liability (and for this purpose $2,500,000 in the aggregate shall be
          deemed not to be material), or any delay in completing the
          Arrangement, to NEWBRIDGE or their respective subsidiaries or
          shareholders (including to NEWBRIDGE's non-participating
          shareholders); and

     (d)  such transaction and its terms and conditions must be satisfactory to
          ALCATEL, acting reasonably (limited to, in the case of a Tuck-in, its
          effect on NEWBRIDGE or its shareholders).

     In the event that such transaction or its terms and conditions are not
     satisfactory to ALCATEL, acting reasonably, or the Ontario Securities
     Commission refuses to grant any relief required in connection with any such
     transaction, ALCATEL will use its reasonable best efforts, for a period not
     to exceed 15 Business Days to assist NEWBRIDGE and the Shareholders in
     structuring such a transaction in a manner satisfactory to ALCATEL, acting
     reasonably.  The parties acknowledge that ALCATEL will require, without
     limitation, that the Arrangement and related matters (after taking into
     account any transaction described herein) be poolable under French GAAP and
     not objectionable to the COB or the PSE, and that a Tuck-in does not
     adversely affect these pooling and COB/PSE issues.  In the event that no
     such transaction is satisfactory to ALCATEL, acting reasonably, where it
     used its reasonable best efforts as aforesaid, this shall not affect the
     completion of the Arrangement or this Agreement.


                                      -9-

     This Voting Agreement has been agreed and accepted this 22/nd/ day of
February, 2000.
