                               A G R E E M E N T

          AGREEMENT, dated as of February 22, 2000 (the "Agreement") among
Global Crossing Ltd., a company formed under the laws of Bermuda ("Global
Crossing"), IPC Communications, Inc., a Delaware Corporation ("IPC"), IXnet,
Inc., a Delaware Corporation ("IXnet") and a subsidiary of IPC, and the
individuals signatory hereto (each, a "Holder").

          WHEREAS, Global Crossing, IPC and IXnet propose to enter into an
Agreement and Plan of Merger among Global Crossing Ltd., Georgia Merger Sub
Corporation, IPC Communications, Inc., Idaho Merger Sub Corporation, and IXnet
Inc. (the "Merger Agreement"); and

          WHEREAS, IPC sponsors the IPC Communications, Inc. 1999 Stock
Incentive Plan ("IPC Option Plan") pursuant to which options have been granted
to certain Holders to purchase shares of IPC common stock ("IPC Options"); and

          WHEREAS, IXnet sponsors the IXnet, Inc. 1999 Stock Option Plan ("IXnet
Option Plan") pursuant to which options have been granted to certain Holders to
purchase shares of IXnet common stock ("IXnet Options") (collectively, IPC
Options and IXnet Options shall be referred to as "Options"); and

          WHEREAS, pursuant to Section 2(c) of each of the IPC Option Plan and
the IXnet Option Plan, a "Change of Control" is deemed to occur, inter alia,
upon the approval by the stockholders of the sponsoring corporation of a
transaction of the type contemplated by the Merger Agreement; and

          WHEREAS, pursuant to Section 5(c) of the IPC Option Plan, each IPC
Option shall become vested and exercisable in full immediately prior to a Change
in Control; and

          WHEREAS, pursuant to Section 5(c) of the IXnet Option Plan and Section
5 of the IXnet Option Plan Grant Certificate for Executive Officers ("IXnet
Option Agreement"), 50% of the then unvested IXnet Options shall become
immediately vested, whether or not such IXnet Options are otherwise exercisable
as of such vesting date; and

          WHEREAS, each such Holder wishes to amend such Holder"s Option
Agreements to limit the number of Options that shall become vested in connection
with the Mergers (as such term is defined in the Merger Agreement).

          NOW, THEREFORE, it is hereby agreed by and among Global Crossing, IPC,
IXnet, and each of the Holders whose name appears on the signature pages below,
that:
<PAGE>

                                                                               2

1.  Each Option Agreement of each Holder is hereby amended to provide that,
    notwithstanding the provisions of Section 5 of the IPC Option Plan and the
    IXnet Option Plan and Section 5 of the IXnet Option Agreement, (a) 50% of
    the unvested IPC Options under the IPC Option Agreement (determined in the
    order in which such Options otherwise would vest) and (b) 25% of the
    unvested IXnet Options under the IXnet Option Agreement (determined in the
    order in which such Options otherwise would vest) will become vested on the
    Change in Control arising as a result of the Mergers and such Change in
    Control shall not constitute an event requiring vesting with respect to the
    remaining IPC Options or IXnet Options held by such Holder. Global Crossing
    shall pay to the relevant taxing authorities or, at the option of the
    Holder, shall reimburse the Holder such amount that, on an after-tax basis
    (including federal income, employment and excise taxes, and state and local
    income, employment and excise taxes, if any) equals the excise tax, if any,
    pursuant to Section 4999 of the Code imposed upon the Holder by reason of
    the vesting of such percentage of his or her Options and any subsequent
    vesting of his or her remaining Options, provided, that the aggregate for
    all Holders of such reimbursement shall not exceed $20,000,000, payable as
    follows: with respect to excise taxes imposed upon one or more Holders by
    reason of the vesting of Options on the first date on or following the
    Mergers, such Holders shall be reimbursed their applicable reimbursement
    amounts fully, to the extent the aggregate reimbursements do not exceed
    $20,000,000. If the aggregate reimbursements do exceed $20,000,000, then
    each Holder shall be reimbursed an amount equal to his applicable full
    reimbursement amount, multiplied by a fraction, the numerator of which is
    $20,000,000, and the denominator of which is the aggregate reimbursements
    payable with respect to such date. To the extent the aggregate
    reimbursements on such first date do not exceed $20,000,000, reimbursements
    will be payable on subsequent vesting dates in accordance with the foregoing
    provisions until aggregate reimbursements have totaled $20,000,000. However,
    on each subsequent date, the numerator in the referenced fraction shall be
    adjusted to equal $20,000,000, minus the aggregate reimbursements already
    payable or paid on preceding vesting dates.

2.  Each Holder agrees that, pursuant to the Mergers, all IPC Options and IXnet
    Options then held by such Holder shall be converted into options to acquire
    shares of common stock of Global Crossing ("Rollover Options"), upon the
    terms and conditions set forth in the Merger Agreement.

3.  All Rollover Options held by a Holder with respect to IPC Options or IXnet
    Options that do not vest pursuant to the amendments set forth in Paragraph 1
    will vest over a three (3) year period, as follows: one third on the first
    anniversary of the Closing Date (as such term is defined in the Merger
    Agreement); one third on the second anniversary of the Closing Date; and one
    third on the third anniversary of the Closing Date.

4.  Each Holder agrees that 75% of the sum of the number of common shares of
    Global Crossing (i) acquired by such Holder in connection with the Mergers
    in
<PAGE>

                                                                               3

    respect of shares of IPC or IXnet issued pursuant to option or benefit plans
    of IPC or IXnet, respectively, and (ii) issuable upon the exercise of vested
    Rollover Options (regardless of exercisability) as of the date of the
    Mergers (after giving effect to the amendments set forth in Paragraph 1
    above and Paragraph 6 below (as demonstrated in the attached table))
    (collectively, the "Restricted Shares") may not be transferred without the
    written consent of Global Crossing, provided that (a) on the first
    anniversary of the Mergers, the transfer restriction provided for in this
    Paragraph 4 shall apply to only fifty percent (50%) of such Restricted
    Shares (without regard to any sales or other transfers by such Holder since
    the Mergers), and (b) on the second anniversary of the Mergers, the transfer
    restriction provided for in this Paragraph 4 shall cease to apply to any of
    the Restricted Shares. A table demonstrating the effect of Paragraph 4(ii)
    only is attached, which table is subject to correction for any erroneously
    inserted current Option positions.

5.  Notwithstanding anything herein or in the IPC Option Plan, the IXnet Option
    Plan, or the IXnet Option Certificate to the contrary, in the event of the
    death or Disability (as such term is defined in the IPC Option Plan and the
    IXnet Option Plan) of the Holder, or in the event of the termination of the
    Holder"s employment without Cause (as such term is defined in the IPC Option
    Plan) or by the Holder for Good Reason (as such term is defined in the IXnet
    Option Certificate, except for such changes as are necessitated by reason of
    IPC or IXnet no longer being publicly held companies), or in the event of a
    change in control (as such term is defined in the standard option agreement
    for executive officers issued under the 1998 Global Crossing Ltd. Stock
    Incentive Plan as Amended and Restated as of December 7, 1999), all of such
    Holder"s Rollover Options shall immediately vest and become exercisable and
    the transfer restriction set forth in Paragraph 4 above shall cease to apply
    to such Holder.

6.  With respect only to IXnet Options held by David Walsh ("DWalsh"), Global
    Crossing, IPC, IXnet and DWalsh agree that (a) pursuant to Paragraphs 1 and
    2 hereof, in connection with the Change in Control arising in connection
    with the Mergers, DWalsh shall have vested rights in 50% of his IXnet
    Options; (b) he hereby relinquishes and forfeits any additional vested
    rights to his IXnet Options existing immediately prior to the Change in
    Control arising in connection with the Mergers; (c) all of his unexercised
    vested and unvested IXnet Options shall be converted into Rollover Options;
    and (d) all such unvested Rollover Options shall vest in accordance with
    Paragraphs 3 and 5 hereof.

7.  This Agreement may be executed by the parties hereto on any number of
    separate counterparts, and all such counterparts so executed shall
    constitute one agreement binding on all the parties notwithstanding that all
    the parties are not signatories to the same counterpart.

    and are enforceable by or against the parties and their respective heirs,

    successors and assigns.

10. Whenever possible, each provision or portion of any provision of this
    Agreement will be interpreted in such manner as to be effective and valid
    under applicable law but if any provision or portion of any provision of
    this Agreement is held to be invalid, illegal or unenforceable in any

               --------------------

               2.1 Election of Directors.

                        2.1.1 Effective immediately at the Closing:

               (a) the number of directors comprising the entire Company Board
shall at all times be seven (7), nine (9) or eleven (11);
<PAGE>

               (b) for so long as the number of directors comprising the entire

collectively shall have the right to nominate one (1) person for election to the

collectively shall have the right to nominate two persons for election to the
Company Board.

            2.1.2 If at any time more Investor Nominees are serving on the
Company Board than are entitled to serve on the Company Board pursuant to this
Section 2.1, the requisite number of Investor Nominees shall immediately resign

to the contrary, at any time that Charterhouse and its Permitted Transferees are
no longer entitled to nominate persons for election to the Company Board, the
Company Board may be reduced or increased at the option of the Company.

resignations and filling of vacancies on the Company Board, the Company Board
shall take all actions necessary (through redesignation of classes of directors
or otherwise) to cause the classes of directors on the Company Board after the

Nominees allocated as evenly as possible in number among the various classes of
directors on the Company Board.

        2.2 Removal and Replacement of Directors.

            2.2.1 Removal of Investor Nominees. If at any time Charterhouse
notifies the Company Board of its wish to remove any Investor Nominee, the
Company Board shall vote so as to remove such Investor Nominee provided that
such Investor Nominee can be removed in accordance with the Company's Bylaws and
the Delaware General Corporation Law. Removal of an Investor Nominee by the
Company Board requires the prior written consent of Charterhouse unless such
removal is based upon the gross negligence or wilfull misconduct of the Investor
Nominee.

            2.2.2 Replacement of Directors. If at any time, a vacancy is created
on the Company Board by reason of the incapacity, death, removal (other than by
action of the Company's Stockholders) or resignation of any Investor Nominee,
then Charterhouse shall designate an individual to fill such vacancy. If

                                       3
<PAGE>

election to the Company Board and the Stockholders fail to elect such Investor
Nominee, Charterhouse shall be entitled to designate a substitute Investor
Nominee to fill any vacancy created thereby.

Company at which directors are elected, the nominees for directors proposed by

Agreement.

the Company Board.

            2.3.2 The Investor Nominees shall be entitled to compensation and
indemnification rights similar to those of other non-employee directors of the
Company. The Company shall at all times maintain a directors' and officers'
insurance policy covering the Investor Nominees that provides in the aggregate
substantially no less coverage than the policy covering the current directors of
the Company as of the date of this Agreement.
