                                                               Exhibit 4.(c)(ii)

                            INDEMNIFICATION AGREEMENT


      THIS AGREEMENT is entered into, effective as of 29 June 2000 between Madge
Networks N.V., a corporation organized under the laws of The Netherlands (the
"Company"), and Alex Vieux ("Indemnitee").

      WHEREAS, it is essential to the Company and its subsidiaries to retain and
attract as directors and officers the most capable persons available;

      WHEREAS, Indemnitee has agreed to serve as a director or as an officer of
the Company or its subsidiaries;

      WHEREAS, both the Company and Indemnitee recognize the increased risk of
litigation and other claims currently being asserted against directors and
officers of corporations; and

      WHEREAS, in recognition of Indemnitee's need for substantial protection
against personal liability in order to enhance Indemnitee's continued and
effective service to the Company and its subsidiaries, and in order to induce
Indemnitee to provide services to the Company or one of its subsidiaries as a
director or an officer, the Company wishes to provide in this Agreement for the
indemnification of and the advancing of expenses to Indemnitee to the fullest
extent (whether partial or complete) permitted by law and as set forth in this
Agreement, and, to the extent insurance is maintained, for the coverage of
Indemnitee under the Company's directors' and officers' liability insurance
policies.

      NOW, THEREFORE, in consideration of the above premises and of Indemnitee's
continuing to serve the Company directly or, at its request, with another
enterprise, and intending to be legally bound hereby, the parties agree as
follows:

      1.    Certain Definitions:

            a. Board: the Board of the Company.

            b. Change in Control: shall be deemed to have occurred if (i) any
"person" (as such term is used in Sections 13(d) and 14(d) of the Securities Act
of 1934, as amended), other than a trustee or other fiduciary holding securities
under an employee benefit plan of the Company or a corporation owned directly or
indirectly by the shareholders of the Company in substantially the same
proportions as their ownership of stock of the Company, is or becomes the
"Beneficial Owner" (as defined in Rule 13d-3 under said Act), directly or
indirectly, of securities of the Company representing 20% or more of the total
voting power represented by the Company's then outstanding Voting Securities, or
(ii) during any period of two consecutive years, individuals who at the
beginning of such period constitute the Board and any new director whose
election by the Board or nomination for election by the Company's shareholders
was approved by a vote of at least two-thirds (2/3) of the directors then still
in office who either were directors at the beginning of the period or whose
election or nomination for election was previously so


                                      403
<PAGE>   2


approved, cease for any reason to constitute a majority thereof, or (iii) the
shareholders of the Company approve a merger or consolidation of the Company
with any other corporation, other than a merger or consolidation that would
result in the Voting Securities of the Company outstanding immediately prior
thereto continuing to represent (either by remaining outstanding or by being
converted into Voting Securities of the surviving entity) at least 80% of the
total voting power represented by the Voting Securities of the Company or such
surviving entity outstanding immediately after such merger or consolidation, or
the shareholders of the Company approve a plan of complete liquidation of the
Company or an agreement for the sale or disposition by the Company (in one
transaction or a series of transactions) of all or substantially all of the
Company's assets.

            c. Expenses: any expense, liability, or loss, including attorneys'
fees, judgments, fines, ERISA excise taxes and penalties, amounts paid or to be
paid in settlement, any interest, assessments, or other charges imposed thereon,
and any federal, state, local, or foreign taxes imposed as a result of the
actual or deemed receipt of any payments under this Agreement, paid or incurred
in connection with investigating, defending, being a witness in, or
participating in (including on appeal), or preparing for any of the foregoing
in, any Proceeding relating to any Indemnifiable Event.

            d. Indemnifiable Event: any event or occurrence that takes place
either prior to or after the execution of this Agreement, related to the fact
that Indemnitee is or was a director or an officer of the Company or a
subsidiary of the Company, or while a director or officer is or was serving at
the request of the Company as a director, officer, employee, trustee, agent, or
fiduciary of another foreign or domestic corporation, partnership, joint
venture, employee benefit plan, trust, or other enterprise, or was a director,
officer, employee, or agent of a foreign or domestic corporation that was a
predecessor corporation of the Company or of another enterprise at the request
of such predecessor corporation, or related to anything done or not done by
Indemnitee in any such capacity, whether or not the basis of the Proceeding is
alleged action in an official capacity as a director, officer, employee, or
agent or in any other capacity while serving as a director, officer, employee,
or agent of the Company, as described above.

            e. Independent Counsel: the person or body appointed in connection
with Section 3.

            f. Potential Change in Control: shall be deemed to have occurred if
(i) the Company enters into an agreement or arrangement, the consummation of
which would result in the occurrence of a Change in Control; (ii) any person
(including the Company) publicly announces an intention to take or to consider
taking actions that, if consummated, would constitute a Change in Control; (iii)
any person (other than a trustee or other fiduciary holding securities under an
employee benefit plan of the Company acting in such capacity or a corporation
owned, directly or indirectly, by the shareholders of the Company in
substantially the same proportions as their ownership of stock of the Company),
who is or becomes the Beneficial Owner, directly or indirectly, of securities of
the Company representing 10% or more of the combined voting power of the
Company's then outstanding Voting Securities, increases his beneficial ownership
of such securities by 5% or more over the percentage so owned by such


                                      404
<PAGE>   3


person on the date hereof, or (iv) the Board adopts a resolution to the effect
that, for purposes of this Agreement, a Potential Change in Control has
occurred.

            g. Proceeding: any threatened, pending, or completed action, suit,
or proceeding, or any inquiry, hearing, or investigation, whether conducted by
the Company or any other party, that Indemnitee in good faith believes might
lead to the institution of any such action, suit, or proceeding, whether civil,
criminal, administrative, investigative, or other.

            h. Reviewing Party: the person or body appointed in accordance with
Section 3.

            i. Voting Securities: any securities of the Company that vote
generally in the election of directors.

      2.    Agreement to Indemnify.

            a. General Agreement. In the event Indemnitee was, is, or becomes a
party to or witness or other participant in, or is threatened to be made a party
to or witness or other participant in, a Proceeding by reason of (or arising in
part out of) an Indemnifiable Event, the Company shall indemnify Indemnitee from
and against any and all Expenses to the fullest extent permitted by law, as the
same exists or may hereafter be amended or interpreted (but in the case of any
such amendment or interpretation, only to the extent that such amendment or
interpretation permits the Company to provide broader indemnification rights
than were permitted prior thereto). The parties hereto intend that this
Agreement shall provide for indemnification in excess of that expressly
permitted by statute, including, without limitation, any indemnification
provided by the Company's Articles of Association, vote of its shareholders or
disinterested directors, or applicable law.

            b. Initiation of Proceeding. Notwithstanding anything in this
Agreement to the contrary, Indemnitee shall not be entitled to indemnification
pursuant to this Agreement in connection with any Proceeding initiated by
Indemnitee against the Company or any director or officer of the Company or a
subsidiary of the Company unless (i) the Company has joined in or the Board has
consented to the initiation of such Proceeding; (ii) the Proceeding is one to
enforce indemnification rights under Section 5; or (iii) the Proceeding is
instituted after a Change in Control and Independent Counsel has approved its
initiation.

            c. Expense Advances. If so requested by Indemnitee, the Company
shall advance (within ten business days of such request) any and all Expenses to
Indemnitee (an "Expense Advance"); provided that, if and to the extent that the
Reviewing Party determines that Indemnitee would not be permitted to be so
indemnified under applicable law, the Company shall be entitled to be reimbursed
by Indemnitee (who hereby agrees to reimburse the Company) for all such amounts
theretofore paid. If Indemnitee has commenced legal proceedings in a court of
competent jurisdiction to secure a determination that Indemnitee should be
indemnified under applicable law, as provided in Section 4, any determination
made by the Reviewing Party that Indemnitee would not be permitted to be
indemnified under applicable law shall not be binding


                                      405
<PAGE>   4


and Indemnitee shall not be required to reimburse the Company for any Expense
Advance until a final judicial determination is made with respect thereto (as to
which all rights of appeal therefrom have been exhausted or have lapsed).
Indemnitee's obligation to reimburse the Company for Expense Advances shall be
unsecured and no interest shall be charged thereon.

            d. Mandatory Indemnification. Notwithstanding any other provision of
this Agreement, to the extent that Indemnitee has been successful on the merits
in defense of any Proceeding relating in whole or in part to an Indemnifiable
Event or in defense of any issue or matter therein, Indemnitee shall be
indemnified against all Expenses incurred in connection therewith.

            e. Partial Indemnification. If Indemnitee is entitled under any
provision of this Agreement to indemnification by the Company for some or a
portion of Expenses, but not, however, for the total amount thereof, the Company
shall nevertheless indemnify Indemnitee for the portion thereof to which
Indemnitee is entitled.

            f. Prohibited Indemnification. No indemnification pursuant to this
Agreement shall be paid by the Company in the event Indemnitee is found in the
applicable Proceeding to have committed gross negligence or an intentionally
wrongful act.

      3.    Reviewing Party.

      Prior to any Change in Control, the Reviewing Party shall be any
appropriate person or body consisting of a member or members of the Board or any
other person or body appointed by the Board who is not a party to the particular
Proceeding with respect to which Indemnitee is seeking indemnification; after a
Change in Control, the Reviewing Party shall be the Independent Counsel referred
to below. With respect to all matters arising after a Change in Control (other
than a Change in Control approved by a majority of the directors on the Board
who were directors immediately prior to such Change in Control) concerning the
rights of Indemnitee to indemnity payments and Expense Advances under this
Agreement or any other agreement or under applicable law or the Company's
Articles of Association now or hereafter in effect relating to indemnification
for Indemnifiable Events, the Company shall seek legal advice only from
Independent Counsel selected by Indemnitee and approved by the Company (which
approval shall not be unreasonably withheld), and who has not otherwise
performed services for the Company or the Indemnitee (other than in connection
with indemnification matters) within the last five years. The Independent
Counsel shall not include any person who, under the applicable standards of
professional conduct then prevailing, would have a conflict of interest in
representing either the Company or Indemnitee in an action to determine
Indemnitee's rights under this Agreement. Such counsel, among other things,
shall render its written opinion to the Company and Indemnitee as to whether and
to what extent the Indemnitee should be permitted to be indemnified under
applicable law. The Company agrees to pay the reasonable fees of the Independent
Counsel and to indemnify fully such counsel against any and all expenses
(including attorneys' fees), claims, liabilities, loss, and damages arising out
of or relating to this Agreement or the engagement of Independent Counsel
pursuant hereto.

      4.    Indemnification Process and Appeal.

            a. Indemnification Payment. Indemnitee shall be entitled to
indemnification of Expenses, and shall receive payment thereof, from the Company
in accordance with this Agreement as soon as practicable after Indemnitee has
made written demand on the Company for indemnification, unless the Reviewing
Party has given a written opinion to the Company that Indemnitee is not entitled
to indemnification under applicable law.

            b. Suit to Enforce Rights. Regardless of any action by the Reviewing
Party, if Indemnitee has not received full indemnification within thirty days
after making a demand in accordance with Section 4(a), Indemnitee shall have the
right to enforce its indemnification rights under this Agreement by commencing
litigation in any court in The Netherlands having subject matter jurisdiction
thereof and in which venue is proper seeking an initial determination by the
court or challenging any determination by the Reviewing Party or any aspect
thereof. The Company hereby consents to service of process and to appear in any
such proceeding. Any determination by the Reviewing Party not challenged by the
Indemnitee shall be binding on the Company and Indemnitee. The remedy provided
for in this Section 4 shall be in addition to any other remedies available to
Indemnitee in law or equity.

            c. Defense to Indemnification, Burden of Proof, and Presumptions. It
shall be a defense to any action brought by Indemnitee against the Company to
enforce this Agreement (other than an action brought to enforce a claim for
Expenses incurred in defending a Proceeding in advance of its final disposition
where the required undertaking has been tendered to the Company) that it is not
permissible under applicable law for the Company to indemnify Indemnitee for the
amount claimed. In connection with any such action or any determination by the
Reviewing Party or otherwise as to whether Indemnitee is entitled to be
indemnified hereunder, the burden of proving such a defense or determination
shall be on the Company. Neither the failure of the Reviewing Party or the
Company (including its Board, independent legal counsel, or its shareholders) to
have made a determination prior to the commencement of such action by Indemnitee
that indemnification of the claimant is proper under the circumstances because
he has met the standard of conduct set forth in applicable law, nor an actual
determination by the Reviewing Party or Company (including its Board,
independent legal counsel, or its shareholders) that the Indemnitee had not met
such applicable standard of conduct, shall be a defense to the action or create
a presumption that the Indemnitee has not met the applicable standard of
conduct. For purposes of this Agreement, the termination of any claim, action,
suit, or proceeding, by judgment, order, settlement (whether with or without
court approval), conviction, or upon a plea of nolo contendere, or its
equivalent, shall not create a presumption that Indemnitee did not meet any
particular standard of conduct or have any particular belief or that a court has
determined that indemnification is not permitted by applicable law.


                                      407
<PAGE>   6


      5.    Indemnification for Expenses Incurred in Enforcing Rights.

      The Company shall indemnify Indemnitee against any and all Expenses and,
if requested by Indemnitee, shall (within ten business days of such request),
advance such Expenses to Indemnitee, that are incurred by Indemnitee in
connection with any claim asserted against or action brought by Indemnitee for

            (i)   indemnification of Expenses or Expense Advances by the Company
                  under this Agreement or any other agreement or under
                  applicable law or the Company's Articles of Association now or
                  hereafter in effect relating to indemnification for
                  Indemnifiable Events, and/or

            (ii)  recovery under directors' and officers' liability insurance
                  policies maintained by the Company, regardless of whether
                  Indemnitee ultimately is determined to be entitled to such
                  indemnification, Expense Advances, or insurance recovery, as
                  the case may be.

      6.    Notification and Defense of Proceeding.

            a. Notice. Promptly after receipt by Indemnitee of notice of the
commencement of any Proceeding, Indemnitee will, if a claim in respect thereof
is to be made against the Company under this Agreement, notify the Company of
the commencement thereof; but the omission so to notify the Company will not
relieve it from any liability that it may have to Indemnitee, except as provided
in Section 6(c).

            b. Defense. With respect to any Proceeding as to which Indemnitee
notifies the Company of the commencement thereof, the Company will be entitled
to participate in the Proceeding at its own expense and except as otherwise
provided below, to the extent the Company so wishes, it may assume the defense
thereof with counsel reasonably satisfactory to Indemnitee. After notice from
the Company to Indemnitee of its election to assume the defense of any
Proceeding, the Company will not be liable to Indemnitee under this Agreement or
otherwise for any Expenses subsequently incurred by Indemnitee in connection
with the defense of such Proceeding other than reasonable costs of investigation
or as otherwise provided below. Indemnitee shall have the right to employ his
own counsel in such Proceeding, but all Expenses related thereto incurred after
notice from the Company of its assumption of the defense shall be at
Indemnitee's expense unless: (i) the employment of counsel by Indemnitee has
been authorized by the Company, (ii) Indemnitee has reasonably determined that
there may be a conflict of interest between Indemnitee and the Company in the
defense of the Proceeding, (iii) after a Change in Control, the employment of
counsel by Indemnitee has been approved by the Independent Counsel, or (iv) the
Company shall not in fact have employed counsel to assume the defense of such
Proceeding, in each of which case all Expenses of the Proceeding shall be borne
by the Company. The Company shall not be entitled to assume the defense of any
Proceeding brought by or on behalf of the Company or as to which Indemnitee
shall have made the determination provided for in (ii) above.


                                      408
<PAGE>   7


            c. Settlement of Claims. The Company shall not be liable to
indemnify Indemnitee under this Agreement or otherwise for any amounts paid in
settlement of any Proceeding effected without the Company's written consent,
provided, however, that if a Change in Control has occurred, the Company shall
be liable for indemnification of Indemnitee for amounts paid in settlement if
the Independent Counsel has approved the settlement. The Company shall not
settle any Proceeding in any manner that would impose any penalty or limitation
on Indemnitee without Indemnitee's written consent. Neither the Company nor the
Indemnitee will unreasonably withhold their consent to any proposed settlement.
The Company shall not be liable to indemnify the Indemnitee under this Agreement
with regard to any judicial award if the Company was not given a reasonable and
timely opportunity, at its expense, to participate in the defense of such
action; the Company's liability hereunder shall not be excused if participation
in the Proceeding by the Company was barred by this Agreement.

      7.    Establishment of Trust.

      In the event of a Change in Control or a Potential Change in Control, the
Company shall, upon written request by Indemnitee, create a Trust under the law
of an appropriate jurisdiction which recognizes trusts as legal entities for the
benefit of the Indemnitee and from time to time upon written request of
Indemnitee shall fund the Trust in an amount sufficient to satisfy any and all
Expenses reasonably anticipated at the time of each such request to be incurred
in connection with investigating, preparing for, participating in, and/or
defending any Proceeding relating to an Indemnifiable Event. The amount or
amounts to be deposited in the Trust pursuant to the foregoing funding
obligation shall be determined by the Reviewing Party. The terms of the Trust
shall provide that upon a Change in Control, (i) the Trust shall not be revoked
or the principal thereof invaded, without the written consent of the Indemnitee,
(ii) the Trustee shall advance, within ten business days of a request by the
Indemnitee, any and all Expenses to the Indemnitee (and the Indemnitee hereby
agrees to reimburse the Trust under the same circumstances for which the
Indemnitee would be required to reimburse the Company under Section 2(c) of this
Agreement), (iii) the Trust shall continue to be funded by the Company in
accordance with the funding obligation set forth above, (iv) the Trustee shall
promptly pay to the Indemnitee all amounts for which the Indemnitee shall be
entitled to indemnification pursuant to this Agreement or otherwise, and (v) all
unexpended funds in the Trust shall revert to the Company upon a final
determination by the Reviewing Party or a court of competent jurisdiction, as
the case may be, that the Indemnitee has been fully indemnified under the terms
of this Agreement. The Trustee shall be chosen by the Indemnitee. Nothing in
this Section 7 shall relieve the Company of any of its obligations under this
Agreement. All income earned on the assets held in the Trust shall be reported
as income by the Company for federal, state, local, and foreign tax purposes.
The Company shall pay all costs of establishing and maintaining the Trust and
shall indemnify the Trustee against any and all expenses (including attorneys'
fees), claims, liabilities, loss, and damages arising out of or relating to this
Agreement or the establishment and maintenance of the Trust.


                                      409
<PAGE>   8


      8.    Non-Exclusivity.

      The rights of Indemnitee hereunder shall be in addition to any other
rights Indemnitee may have under the Company's Articles of Association,
applicable law, or otherwise. To the extent that a change in applicable law
(whether by statute or judicial decision) permits greater indemnification by
agreement than would be afforded currently under the Company's Articles of
Association, applicable law, or this Agreement, it is the intent of the parties
that Indemnitee enjoy by this Agreement the greater benefits so afforded by such
change.

      9.    Liability Insurance.

      To the extent the Company maintains an insurance policy or policies
providing directors' and officers' liability insurance, once Indemnitee becomes
a director, Indemnitee shall be covered by such policy or policies, in
accordance with its or their terms, to the maximum extent of the coverage
available for any Company director or officer.

      10.   Period of Limitations.

      No legal action shall be brought and no cause of action shall be asserted
by or on behalf of the Company or any affiliate of the Company against
Indemnitee, Indemnitee's spouse, heirs, executors, or personal or legal
representatives after the expiration of two years from the date of accrual of
such cause of action, or such longer period as may be required by state law
under the circumstances. Any claim or cause of action of the Company or its
affiliate shall be extinguished and deemed released unless asserted by the
timely filing of a legal action within such period; provided, however, that if
any shorter period of limitations is otherwise applicable to any such cause of
action the shorter period shall govern.

      11.   Amendment of this Agreement.

      No supplement, modification, or amendment of this Agreement shall be
binding unless executed in writing by both of the parties hereto. No waiver of
any of the provisions of this Agreement shall operate as a waiver of any other
provisions hereof (whether or not similar), nor shall such waiver constitute a
continuing waiver. Except as specifically provided herein, no failure to
exercise or any delay in exercising any right or remedy hereunder shall
constitute a waiver thereof.

      12.   Subrogation.

      In the event of payment under this Agreement, the Company shall be
subrogated to the extent of such payment to all of the rights of recovery of
Indemnitee, who shall execute all papers required and shall do everything that
may be necessary to secure such rights, including the execution of such
documents necessary to enable the Company effectively to bring suit to enforce
such rights.


                                      410
<PAGE>   9


      13.   No Duplication of Payments.

      The Company shall not be liable under this Agreement to make any payment
in connection with any claim made against Indemnitee to the extent Indemnitee
has otherwise received payment (under any insurance policy, or otherwise) of the
amounts otherwise indemnifiable hereunder.

      14.   Binding Effect.

      This Agreement shall be binding upon and inure to the benefit of and be
enforceable by the parties hereto and their respective successors (including any
direct or indirect successor by purchase, merger, consolidation, or otherwise to
all or substantially all of the business and/or assets of the Company), assigns,
spouses, heirs, and personal and legal representatives. The Company shall
require and cause any successor (whether direct or indirect by purchase, merger,
consolidation, or otherwise) to all, substantially all, or a substantial part,
of the business and/or assets of the Company, by written agreement in form and
substance satisfactory to Indemnitee, expressly to assume and agree to perform
this Agreement in the same manner and to the same extent that the Company would
be required to perform if no such succession had taken place. The
indemnification provided under this Agreement shall continue as to Indemnitee
for any action taken or not taken while serving in an indemnified capacity
pertaining to an Indemnifiable Event even though he may have ceased to serve in
such capacity at the time of any Proceeding.

      15.   Severability.

      If any provision (or portion thereof) of this Agreement shall be held by a
court of competent jurisdiction to be invalid, void, or otherwise unenforceable,
the remaining provisions shall remain enforceable to the fullest extent
permitted by law. Furthermore, to the fullest extent possible, the provisions of
this Agreement (including, without limitation, each portion of this Agreement
containing any provision held to be invalid, void, or otherwise unenforceable,
that is not itself invalid, void, or unenforceable) shall be construed so as to
give effect to the intent manifested by the provision held invalid, void, or
unenforceable.

      16.   Governing Law.

      This Agreement shall be governed by and construed and enforced in
accordance with the laws of The Netherlands.

      17.   Notices.

      All notices, demands, and other communications required or permitted
hereunder shall be made in writing and shall be deemed to have been duly given
if delivered by hand, against receipt, or mailed, postage prepaid, certified or
registered mail, return receipt requested, and addressed to:
