                          CHANGE IN CONTROL AGREEMENT

          This Agreement, dated __________________________, 2000,  is made by
and between Global Crossing Ltd., a Bermuda Corporation (as hereinafter defined,
the "Corporation"), and _____________  __________ (the "Executive").

          WHEREAS, the Board (as hereinafter defined) recognizes that the
possibility of a Change in Control (as hereinafter defined) of the Corporation
exists and that such possibility, and the uncertainty it may cause, may result
in the departure or distraction of key management employees of the Corporation;
and

          WHEREAS, the Executive is a key management employee of the Corporation
or of a Subsidiary; and

          WHEREAS, the Board has determined that the Corporation should
encourage the continued employment of the Executive by the Corporation or a
Subsidiary and the continued dedication of the Executive to his assigned duties
without distraction as a result of the circumstances arising from the
possibility of a Change in Control;

          NOW THEREFORE, in consideration of the premises and the mutual
covenants herein contained, the Corporation and the Executive hereby agree as
follows:

          1.   Defined Terms.  For purposes of this Agreement, the following
               -------------
terms shall have the meanings indicated below:

          (A)  "Board" shall mean the Board of Directors of the Corporation, as
     constituted from time to time.

     employment shall mean (i) the willful failure by the Executive
     substantially to perform the Executive's duties with the Corporation or a
     Subsidiary, other than any failure resulting from the Executive's
     incapacity due to physical or mental illness or any actual or anticipated
     failure after the issuance of a Notice of Termination for Good Reason by
     the Executive in accordance with paragraph (A) of Section 6, that continues
     for at least 30 days after the Board delivers to the Executive a written
     demand for performance that identifies specifically and in detail the
     manner in which the Board believes that the Executive willfully has failed
     substantially to perform the Executive's duties, (ii) the willful engaging
     by the Executive in misconduct that is demonstrably and materially
     injurious to the Corporation or any Subsidiary, monetarily or otherwise or

     determinable physical or mental impairment which constitutes a permanent
     and total disability, as defined in Section 22(e)(3) of the Code (or any

          prior to the Change in Control. For this purpose, long-term incentive
          opportunities shall be measured as of the date of grant using a
          methodology consistent with prior long-term incentive grant practices.

                                                                               4

                    (iii) the relocation of the Executive's principal place of
          employment to a location more than 35 miles from the location of such
          principal place of employment immediately prior to the Change in

                    (v)   the failure by the Corporation to continue to provide
          the Executive with benefits as favorable in the aggregate and in all
          material respects as those enjoyed by the Executive under the
          Corporation's retirement, life insurance, medical, health and
          accident, disability, or other employee benefit plans in which the
          Executive was participating immediately prior to the Change in
          Control; or the failure by the Corporation to provide the Executive
          with the number of paid vacation days to which the Executive was
          entitled in accordance with the Corporation's normal vacation policy
          in effect immediately prior to the Change in Control; or

                    (vi)  any purported termination by the Corporation of the
          Executive's employment that is not effected in accordance with a
          Notice of Termination satisfying the requirements of paragraph (A) of
          Section 6 hereof.

          (J)  "Notice of Termination" shall have the meaning stated in
     paragraph (A) of Section 6 hereof.

          (K)  "Payment Trigger" shall mean the occurrence of both of (i) a
     Change in Control during the term of this Agreement and (ii) at any time on
     or after such Change in Control, but before the end of the Protected
     Period, the termination of the Executive's employment with the Corporation
     or a Subsidiary for any reason other than (A) by the Executive without Good
     Reason, (B) by the Corporation (or a Subsidiary) as a result of the
     Disability of the Executive or with Cause or (C) as a result of the death
     of the Executive; provided, however, that if the Executive's employment is
     terminated prior to a Change in Control at the request of a Person engaged
     in a transaction or series of transactions that would result in a Change in
     Control, such termination shall be deemed to occur during the Protected
     Period. Any transfer of the Executive's employment from the Corporation to
     a Subsidiary, from a Subsidiary to the Corporation, or from one Subsidiary
     to another Subsidiary shall not by itself constitute a termination of the
     Executive's employment for purposes of this Agreement.

          (L)  "Person" shall have the meaning used in Sections 13(d) and 14(d)
     of the Securities Exchange Act of 1934, as amended from time to time.

                                                                               5

          (M)  "Protected Period" shall mean the 24-month period immediately
     following the month in which a Change in Control occurs.

          (N)  "Subsidiary" shall mean any corporation or other entity or
     enterprise, whether incorporated or unincorporated, of which at least a
     majority of the securities or other interests having by their terms
     ordinary voting power to elect a majority of the board of directors or
     others serving similar functions with respect to such corporation or other
     entity or enterprise is owned by the Corporation, directly or indirectly.

          2.   Term of Agreement.  This Agreement will become effective on the
               -----------------
date hereof and shall continue in effect through December 31, 2001 (the
"Initial Term").

          The Initial Term of this Agreement automatically shall be extended for
one (1) additional year at the end of the Initial Term, and then again after
each successive one (1) year period thereafter (each such one (1) year period
following the Initial Term a "Successive Period"). However, either party may
terminate this Agreement at the end of the Initial Term, or at the end of any
Successive Period thereafter, by giving the other party written notice of intent
not to renew, delivered at least one (1) year prior to the end of such Initial
Term or Successive Period. If such notice is properly delivered by either party,
this Agreement, along with all corresponding rights, duties, and covenants shall
automatically expire at the end of the Initial Term or Successive Period then in
progress.

          In the event that a Change in Control of the Corporation occurs (as
such term is herein defined) during the Initial Term or any Successive Period,
upon the effective date of such Change in Control, the term of this Agreement
shall automatically and irrevocably be renewed for a period of twenty-four (24)
full calendar months from the effective date of such Change in Control. This
Agreement shall thereafter automatically terminate following the twenty-four
(24) month Change-in-Control renewal period. Further, this Agreement shall be
assigned to, and shall be assumed by the purchaser in such Change in Control, as
further provided in Section 9 herein.

          3.   General Provisions.
               ------------------

          (A)  The Corporation hereby represents and warrants to the Executive
as follows: The execution and delivery of this Agreement and the performance by
the Corporation of the actions contemplated hereby have been duly authorized by
all necessary corporate action on the part of the Corporation. This Agreement is
a legal, valid and legally binding obligation of the Corporation enforceable in
accordance with its terms. Neither the execution or delivery of this Agreement
nor the consummation by the Corporation of the actions contemplated hereby (i)
will violate any provision of the certificate of incorporation or bye-laws (or
other charter documents) of the Corporation, (ii) will violate or be in conflict
with any applicable law or any judgment, decree, injunction or order of any
court or governmental agency or authority, or (iii) will violate or conflict
with or constitute a default (or an event which, with notice or lapse of time or
both, would constitute a default) under or will result in the termination of,
accelerate the performance
<PAGE>

                                                                               6

required by, or result in the creation of any lien, security interest, charge or
encumbrance upon any of the assets or properties of the Corporation under, any
term or provision of the certificate of incorporation or bye-laws (or other
charter documents) of the Corporation or of any contract, commitment,
understanding, arrangement, agreement or restriction of any kind or character to
which the Corporation is a party or by which the Corporation or any of its
properties or assets may be bound or affected.

          (B)  No amount or benefit shall be payable under this Agreement unless
there shall have occurred a Payment Trigger during the term of this Agreement.
In no event shall payments in accordance with this Agreement be made in respect
of more than one Payment Trigger.

          (C)  This Agreement shall not be constructed as creating an express or
implied contract of employment and, except as otherwise agreed in writing
between the Executive and the Corporation, the Executive shall not have any
right to be retained in the employ of the Corporation or of a Subsidiary.
Notwithstanding the immediately preceding sentence or any other provision of
this Agreement, no purported termination of the Executive's employment that is
not effected in accordance with a Notice of Termination satisfying paragraph (A)
of Section 6 shall be effective for purposes of this Agreement. The Executive's
right, following the occurrence of a Change in Control, to terminate his
employment under this Agreement for Good Reason shall not be affected by the
Executive's Disability or incapacity. The Executive's continued employment shall
not constitute consent to, or a waiver of rights with respect to, any act or
failure to act constituting Good Reason under this Agreement.

          4.   Payments Due Upon a Payment Trigger.
               -----------------------------------

          (A)  The Corporation shall pay to the Executive the payments described
in this Section 4 upon the occurrence of a Payment Trigger during the term of
this Agreement.

          (B)  Upon the occurrence of a Payment Trigger during the term of this
Agreement, the Corporation shall pay to the Executive a lump sum payment, in
cash, equal to the product of:

                    (i)  three multiplied by

                   (ii)  the sum of --

                              (a)  the higher of the Executive's (1) annual base
                         salary in effect immediately prior to the occurrence of
                         the Change in Control or (2) the Executive's annual
                         base salary in effect immediately prior to the Payment
                         Trigger, plus

                              (b)  the higher of (1) the Executive's target
                         annual bonus for the fiscal year (or other measuring
                         period) prior to the fiscal
<PAGE>

                                                                               7

                         year (or other measuring period) in which the Change in
                         Control occurs or (2) the Executive's target annual
                         bonus for the fiscal year (or other measuring period)
                         in which the Payment Trigger occurs.

          The amount determined under the foregoing provisions of this paragraph
(B) shall be reduced by any cash severance benefit otherwise paid to the
Executive under any applicable severance plan or other severance arrangement.
For purposes of this paragraph (B), amounts payable to the Executive pursuant to
an annual bonus plan for the fiscal year or other measuring period described in
(1) or (2) above, as applicable (the "applicable year/period"), shall not
include amounts attributable to a fiscal year or other measuring period that
commenced prior to the applicable year/period and that become payable during the
applicable year/period.

          (C)  Notwithstanding any provision of any incentive compensation plan,
including, without limitation, any provision of any incentive compensation plan
conditioning the receipt of any payment upon continued employment after the
completed fiscal year or other measuring period, the Corporation shall pay to
the Executive a lump sum amount, in cash, equal to the amount of any incentive
compensation that has been allocated or awarded to the Executive for a completed
fiscal year or other measuring period, preceding the occurrence of a Payment
Trigger under any incentive compensation plan but has not yet been paid to the
Executive.

          (D)  For the fiscal year or other measuring period during which the
Payment Trigger occurs, the Executive shall be entitled to a pro rata bonus
equal to the number of calendar days elapsed during the fiscal year or other
measuring period prior to the Date of Termination divided by the total days in
the fiscal year or measuring period, as the case may be, and multiplied by the
target bonus payable for such period.

          (E)  The payments provided for in paragraphs (B), (C) and (D) of this
Section 4 shall be made not later than the fifth day following the occurrence of
a Payment Trigger, unless the amounts of such payments cannot be finally
determined on or before that day, in which case, the Corporation shall pay to
the Executive on that day an estimate, as reasonably determined in good faith by
the Corporation, of the minimum amount of the payments to which the Executive is
clearly entitled and shall pay the remainder of the payments (together with
interest at the rate provided in section 1274(b)(2)(B) of the Code) as soon as
the amount thereof can be determined but in no event later than the thirtieth
day after the occurrence of a Payment Trigger. In the event the amount of the
estimated payments exceeds the amount subsequently determined to have been due,
the excess shall constitute a loan by the Corporation to the Executive, payable
on the fifth business day after demand by the Corporation (together with
interest at the rate provided in section 1274(b)(2)(B) of the Code). At the time
that payments are made under this Section 4, the Corporation shall provide the
Executive with a written statement setting forth the manner in which the
payments were calculated and the basis for the calculations including, without
limitation, any opinions or other advice the Corporation has received from any
outside counsel, auditors or consultants (and any opinions or advice that are in
writing shall be attached to the statement).
<PAGE>

                                                                               8

          (F)  (i)  In addition to the payments provided for above in this
Section 4, the Corporation shall provide or arrange to provide, at the same cost
to the Executive, and at the same coverage level as in effect as of the Date of
Termination (subject to changes in coverage levels applicable to all employees
who are similarly situated to the Executive prior to the Date of Termination), a
continuation of the Executive's (and the Executive's eligible dependents')
health and life insurance coverages for [thirty-six (36)] [twenty-four (24)]
months from the Date of Termination. The applicable COBRA health insurance
benefit continuation period shall commence at the beginning of this [thirty-six
(36)] [twenty-four (24)] month benefit continuation period.

          (ii) The providing of these health and life insurance benefits by the
Corporation shall be discontinued prior to the end of the [thirty-six (36)]
[twenty-four (24)] month continuation period to the extent that the Executive
becomes covered under the health and/or life insurance coverages of a subsequent
employer; provided that such subsequent employer health insurance coverage does
not contain any exclusion or limitation with respect to any preexisting
condition of the Executive or the Executive's eligible dependents. For purposes
of enforcing this offset provision, the Executive shall have a duty to promptly
inform the Corporation in writing if the Executive becomes covered under the
health and/or life insurance coverages of a subsequent employer.

          5.   Gross-Up Payments.
               -----------------

          (A) In the event it shall be determined that any payment or
distribution by the Corporation or other amount with respect to the Corporation
to or for the benefit of the Executive, whether paid or payable or distributed
or distributable pursuant to the terms of this Agreement or otherwise, but
determined without regard to any additional payments required under this
Section 5 (a "Payment"), is (or will be) subject to the excise tax imposed by
Section 4999 of the Code or any interest or penalties are (or will be) incurred
by the Executive with respect to the excise tax imposed by Section 4999 of the
Code with respect to the Corporation (the excise tax, together with any interest
and penalties, are hereinafter collectively referred to as the "Excise Tax"),
the Executive shall be entitled to receive an additional cash payment (a "Gross-
Up Payment") from the Corporation in an amount equal to the sum of the Excise
Tax and an amount sufficient to pay the cumulative Excise Tax and all cumulative
income taxes (including any interest and penalties imposed with respect to such
taxes) relating to the Gross-Up Payment so that the net amount retained by the
Executive is equal to all payments to which Executive is entitled pursuant to
the terms of this Agreement (excluding the Gross-Up Payment) or otherwise less
income taxes (but not reduced by the Excise Tax or by income taxes attributable
to the Gross-Up Payment).

          (B)  Subject to the provisions of paragraph (C) of this Section 5, all
determinations required to be made under this Section 5, including whether and
when a Gross-Up Payment is required and the amount of such Gross-Up Payment and
the assumptions to be utilized in arriving at the determination, shall be made
by a nationally recognized certified public accounting firm selected by the
Corporation with the consent of the Executive, which should not unreasonably be
withheld (the "Accounting Firm") which shall provide detailed supporting
calculations both to the Corporation and the Executive within 30 days after the
receipt of notice
<PAGE>

                                                                               9

from the Executive that there has been a Payment, or such earlier time as is
requested by the Corporation. All fees and expenses of the Accounting Firm shall
be borne solely by the Corporation. The Corporation, as determined in accordance
with this Section 5, shall pay any Gross-Up Payment to the Executive within five
days after the receipt of the Accounting Firm's determination. If the Accounting
Firm determines that no Excise Tax is payable by the Executive, it shall so
indicate to the Executive in writing. Any determination by the Accounting Firm
shall be binding upon the Corporation and the Executive. As a result of
uncertainty in the application of Section 4999 of the Code at the time of the
initial determination by the Accounting Firm, it is possible that Gross-Up
Payments that the Corporation should have made will not have been made (an
"Underpayment"), consistent with the calculations required to be made hereunder.
In the event the Corporation exhausts its remedies in accordance with paragraph
(C) of this Section 5 and the Executive thereafter is required to make a payment
of any Excise Tax, the Accounting Firm shall determine the amount of
Underpayment that has occurred and the Underpayment shall be promptly paid by
the Corporation to or for the benefit of the Executive.

          (C)  The Executive shall notify the Corporation in writing of any
claim by the Internal Revenue Service that, if successful, would require a
Gross-Up Payment (that has not already been paid by the Corporation). The
notification shall be given as soon as practicable but no later than ten
business days after the Executive is informed in writing of the claim and shall
apprise the Corporation of the nature of the claim and the date on which the
claim is requested to be paid. The Executive shall not pay the claim prior to
the expiration of the 30-day period following the date on which the Executive
gives notice to the Corporation or any shorter period ending on the date that
any payment of taxes with respect to the claim is due. If the Corporation
notifies the Executive in writing prior to the expiration of the 30-day period
that it desires to contest the claim, the Executive shall:

                    (i)   give the Corporation any information reasonably
          requested by the Corporation relating to the claim;

                    (ii)  take any action in connection with contesting the
          claim as the Corporation shall reasonably request in writing from time
          to time, including, without limitation, accepting legal representation
          with respect to the claim by an attorney reasonably selected by the
          Corporation;

                    (iii) cooperate with the Corporation in good faith in order
          effectively to contest the claim; and

                    (iv)  permit the Corporation to participate in any
          proceedings relating to the claim.

          The Corporation shall bear and pay directly all costs and expenses
(including additional interest and penalties) incurred in connection with the
contest and shall indemnify and hold the Executive harmless, on an after-tax
basis, for any Excise Tax or income tax (including interest and penalties with
respect thereto) imposed as a result of the representation and payment
<PAGE>

                                                                              10

of costs and expenses. Without limitation of the forgoing provisions of this
Section 5, the Corporation shall control all proceedings taken in connection
with the contest and, at its sole option, may pursue or forego any and all
administrative appeals, proceedings, hearings, and conferences with the taxing
authority in respect of the claim and may, at its sole option, either direct the
Executive to pay the tax claimed and sue for a refund or contest the claim in
any permissible manner, and the Executive agrees to prosecute the contest to a
determination before any administrative tribunal, in a court of initial
jurisdiction and in one or more appellate courts, as the Corporation shall
determine. If the Corporation directs the Executive to pay the claim and sue for
a refund, the Corporation shall advance the amount of the payment to the
Executive, on an interest-free basis, and shall indemnify and hold the Executive
harmless, on an after-tax basis, from any Excise Tax or income tax (including
interest or penalties with respect thereto) imposed with respect to the advance
or with respect to any imputed income with respect to the advance; and any
extension of the statute of limitations relating to payment of taxes for the
taxable year of the Executive with respect to which the contested amount is
claimed to be due shall be limited solely to the contested amount. The
Corporation's control of the contest shall be limited to issues with respect to
which a Gross-Up Payment would be payable hereunder and the Executive shall be
entitled to settle or contest, as the case may be, any other issue raised by the
Internal Revenue Service or any other taxing authority.

          (D)  If, after the receipt by the Executive of an amount advanced by
the Corporation pursuant to paragraph (C) of this Section 5, the Executive
becomes entitled to receive any refund with respect to the claim, the Executive
shall, subject to the Corporation's compliance with the requirements of
paragraph (C) of this Section 5, promptly pay to the Corporation the amount of
the refund (together with any interest paid or credited thereon after taxes
applicable thereto). If, after the receipt by the Executive of an amount
advanced by the Corporation pursuant to paragraph (C) of this Section 5, a
determination is made that the Executive shall not be entitled to any refund
with respect to the claim and the Corporation does not notify the Executive in
writing of its intent to contest the denial of refund prior to the expiration of
30 days after the determination, then the advance shall be forgiven and shall
not be required to be repaid and the amount of the advance shall offset, to the
extent thereof, the amount of Gross-Up Payment required to be paid.

          6.   Termination Procedures.
               ----------------------

          (A)  During the term of this Agreement, any purported termination of
the Executive's employment (other than by reason of death) shall be communicated
by written Notice of Termination from one party hereto to the other party hereto
in accordance with Section 10 hereof. For purposes of this Agreement, a "Notice
of Termination" shall mean a written notice that indicates the specific
termination provision in this Agreement relied upon, and, if applicable, the
notice shall set forth in reasonable detail the facts and circumstances claimed
to provide a basis for termination of the Executive's employment under the
provision so indicated. Further, a Notice of Termination for Cause shall include
a copy of a resolution duly adopted by the affirmative vote of not less than a
majority of the entire membership of the Board at a meeting of the Board finding
that, in the informed, reasonable, good faith judgment of the Board,
<PAGE>

                                                                              11

the Executive was guilty of conduct set forth in the definition of Cause in
Section 1(B), and specifying the particulars thereof in detail.

          (B)  "Date of Termination" with respect to any purported termination
of the Executive's employment during the term of the Agreement (other than by
reason of death) shall mean (i) if the Executive's employment is terminated for
Disability, 20 business days after Notice of Termination is given (provided that
the Executive shall not have returned to the full-time performance of the
Executive's duties during that 20 business day period) and (ii) if the
Executive's employment is terminated for any other reason, the date specified in
the Notice of Termination, which, in the case of a termination by the
Corporation, shall not be less than ten business days except in the case of a
termination for Cause, and, in the case of a termination by the Executive, shall
not be less than ten business days nor more than 20 business days, respectively,
after the date such notice of Termination is given.

          7.   No Mitigation.  The Executive shall not be required to seek other
               -------------
employment or to attempt in any way to reduce any amounts payable to the
Executive by the Corporation pursuant to this Agreement. Further, except as
provided in Section 4(E), the amount of any payment or benefit provided for in
this Agreement shall not be reduced by any compensation earned by the Executive
as the result of employment by another employer, by retirement benefits, by
offset against any amount claimed to be owed by the Executive to the Corporation
or a Subsidiary, or otherwise.

          8.   Disputes.
               --------

          (A)  If a dispute or controversy arises out of or in connection with
this Agreement, the parties shall first attempt in good faith to settle the
dispute or controversy by mediation under the Commercial Mediation Rules of the
American Arbitration Association before resorting to arbitration or litigation.
Thereafter, any remaining unresolved dispute or controversy arising out of or in
connection with this Agreement shall, upon a written notice from the Executive
to the Corporation either before suit thereupon is filed or within 20 business
days thereafter, be settled exclusively by arbitration in accordance with the
Commercial Arbitration Rules of the American Arbitration Association in a city
located within the continental United States designated by the Executive.
Judgment may be entered on the arbitrator's award in any court having
jurisdiction. The Executive shall, however, be entitled to seek specific
performance of the Corporation's obligations hereunder during the pendency of
any dispute or controversy arising under or in connection with this Agreement.

          (B)  Any legal action concerning this Agreement, other than a
mediation or an arbitration described in paragraph (A) of this Section 8,
whether instituted by the Corporation or the Executive, shall be brought and
resolved only in a state court of competent jurisdiction located in the
territory that encompasses the city, county, or parish in which the Executive's
principal residence is located at the time such action is commenced. The
Corporation hereby irrevocably consents and submits to and shall take any action
necessary to subject itself to the personal jurisdiction of that court and
hereby irrevocably agrees that all claims in respect of the
<PAGE>

                                                                              12

action shall be instituted, heard, and determined in that court. The Corporation
agrees that such court is a convenient forum, and hereby irrevocably agrees that
all claims in respect of the action shall be instituted, heard, and determined
in that court, and hereby irrevocably waives, to the fullest extent it may
effectively do so, the defense of an inconvenient forum to the maintenance of
the action. Any final judgment in the action may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.

          (C)  The Corporation shall pay all costs and expenses, including
attorneys' fees and disbursements, of the Corporation and, at least monthly, the
Executive in connection with any legal proceeding (including arbitration),
whether or not instituted by the Corporation or the Executive, relating to the
interpretation or enforcement of any provision of this Agreement, provided that
if the Executive instituted the proceeding and the judge, arbitrator, or other
individual presiding over the proceeding affirmatively finds that the Executive
instituted the proceeding in bad faith, the Executive shall pay all costs and
expenses, including attorneys' fees and disbursements, of Executive and the
Corporation. The Corporation shall pay prejudgment interest on any money
judgment obtained by Executive as a result of such proceeding, calculated at the
rate provided in Section 1274(b)(2) (B) of the Code.

     9.   Successors: Binding Agreement.
          -----------------------------

          (A)  In addition to any obligations imposed by law upon any successor
to the Corporation, the Corporation shall require any successor (whether direct
or indirect, by purchase, merger, consolidation, or otherwise) to all or
substantially all of the business or assets of the Corporation expressly to
assume and agree to perform this Agreement in the same manner and to the same
extent that the Corporation would be required to perform it if no such
succession had taken place. Failure of the Corporation to obtain the assumption
and agreement prior to the effectiveness of any succession shall be a breach of
this Agreement and shall entitle the Executive to compensation from the
Corporation in the same amount and on the same terms as the Executive would be
entitled to hereunder if the Executive were to terminate his employment for Good
Reason immediately after a Change in Control and during the term of this
Agreement, except that, for purposes of implementing the foregoing, the date on
which any succession becomes effective shall be deemed the Payment Trigger
occasioned by the foregoing deemed termination of employment for Good Reason
immediately following a Change in Control. The provisions of this Section 9
shall continue to apply to each subsequent employer of Executive bound by this
Agreement in the event of any merger, consolidation, or transfer of all or
substantially all of the business or assets of that subsequent employer.

          (B)  This Agreement shall inure to the benefit of and be enforceable
by the Executive's personal or legal representatives, executor, administrators,
successors, heirs, distributees, devisees, and legatees. If the Executive shall
die while any amount would be payable to the Executive hereunder (other than
amounts which, by their terms, terminate upon the death of the Executive) if the
Executive had continued to live, the amount, unless otherwise provided herein,
shall be paid in accordance with the terms of this Agreement to the executors,
personal representatives, or administrators of the Executive's estate.

waived, or discharged unless such waiver, modification, or discharge is agreed

specifically designated by the Board. No waiver by either party hereto at any
time of any breach by the other party hereto of, or compliance with, any

shall be deemed a waiver of similar or dissimilar provisions or conditions at
the same or at any prior or subsequent time. No agreements or representations,
oral or otherwise, express or implied, with respect to the subject matter hereof
have been made by either party which are not expressly set forth in this

                              EMPLOYMENT AGREEMENT
                          DATED AS OF DECEMBER 3, 1999
                          BETWEEN GLOBAL CROSSING LTD.
                                      AND
                                JOHN A. SCARPATI

     JOHN A. SCARPATI ("Executive") and Global Crossing Ltd. ("Company") hereby
agree as follows:

     1 . Term.  The term of Executive's employment by Company under this
         -----
Agreement (the "Term") shall commence on and as of December 3, 1999 for a three-
year term ending December 3, 2002, and continue thereafter for successive one-
year terms (the initial three-year term and each one-year term thereafter,
collectively the "Term"), unless either Company or Executive gives notice to the
other at least six (6) months in advance of the expiration of the current term
that it wishes to terminate this Agreement, in which event this Agreement shall
terminate as of the end of such term, unless earlier terminated as hereafter
provided.

     2.  Title and Duties.  During the Term, Executive shall be employed by
         ----------------
Company as Chief Administrative Officer ("CAO") world-wide reporting to the
Chief Executive Officer (the "CEO") of the Company.   Executive shall devote his
full-time attention and energies to the business of the Company; provided,
however, that the foregoing shall not preclude Executive from engaging in
charitable and community affairs, or participating as a director of a non
competing business company, or managing his personal passive investments so long
as such activities do not materially interfere with his obligations as CAO.
Executive shall perform such duties, which shall not be inconsistent with his
position as CAO of the Company, as are assigned to him from time to time by the
CEO of the Company, and any other duties undertaken or accepted by Executive
consistent with his position as CAO of the Company.  The Executive shall have
such officers of the Company report to him as Executive and the CEO shall agree
from time to time.

     3.  Salary; Additional Benefit. (a) Executive shall receive a salary of
         --------------------------
$500,000 per annum during the first three (3) years of the Term, payable as set
forth below.  Executive's salary shall be reviewed at least annually and may be
increased but not decreased during the Term.  Salary payments shall be made in
equal installments in accordance with Company's then prevailing payroll policy.

     (b)  If Executive is still employed with the Company at the end of the
initial three year Term (or, if earlier, upon termination of Executive's
employment with the Company under Section 10 (a) (i) or Section 10 (a) (ii) or
any other Non-Fault Termination), Executive shall be entitled to an $8 million
cash payment from the Company or in the discretion of the Company, common stock
which shall be immediately available for sale or transfer.  If stock is
utilized, the value for these purposes shall be determined based upon the
closing price of the common stock

                                       1
<PAGE>

on the NASDAQ market on the date on which the payment becomes due.

     4.  Annual Bonus.   (a)  For each year of the Term, Executive will be
         ------------
eligible for an annual bonus which will be determined by the Board of Directors,
but which shall not be less than $500,000 for the first full year of the Term.
The bonus will be determined thereafter by the Board of Directors and
Executive's target bonus shall be one hundred percent (100 %) of his salary.  In
determining the annual salary and bonus, the Board of Directors shall consider,
among other things, Executive's performance in his capacity as CAO of the
Company.  It is the intent of this Agreement that Executive's total cash
compensation (salary and bonus) shall be appropriate for a CAO and that annual
increases in salary and bonus shall be made, in each event, assuming
satisfactory performance.

     (b)   Within 10 days from the date of commencement of Executive's
employment with the Company, the Company shall pay to Executive a $2 Million
signing bonus, payable in cash.  In the event Executive voluntarily resigns or
his employment is terminated pursuant to Section 10 (a) (iii) or 10 (a) (iv) in
the first year of Executive's employment, Executive shall promptly return to the
Company a portion of such signing bonus equal to the sum of (i) one twelfth
(1/12) of $1,000,000 for each full month of employment Executive does not
complete during such twelve month period plus (ii) $1,000,000.  In the event
Executive's employment terminates prior to the completion by Executive of five
years of employment with the Company (or earlier in the sole discretion of the
Board of Directors of the Company), Executive shall promptly return to the
Company a portion of such signing bonus equal to $1,000,000; provided that this
                                                             --------
obligation shall not apply if Executive's termination of employment constitutes
a Non-Fault Termination or results from a Change in Control (as defined in the
Plan referred to below).

     5.  Stock Options.  Executive shall be granted stock options (the "One
         -------------
Million Options") to purchase an aggregate of One Million (1,000,000) shares of
common stock of the Company.  The One Million Options shall be granted in
accordance with, and subject to the following:

     (a)  The exercise price of the One Million Options shall be equal to $8.00
          plus the closing price of the common stock of the Company on the
          effective date of the grant of the One Million Options by the Board of
          Directors of the Company (which is the date hereof).  The One Million
          Options may be exercised at any time after vesting but prior to
          expiration.

     (b)  The One Million Options shall be subject to the terms and conditions
          of the 1998 Global Crossing Ltd. Stock Incentive Plan, a copy of which
          is attached hereto and incorporated herein by reference as Exhibit A
          (as amended, the "Plan") and a Non-Qualified Stock Option Agreement,
          the form of which is attached and incorporated herein by reference as

     (c) The One Million Options shall vest according to the following schedule:

          The vesting schedule shall be accelerated in the event of a Non-Fault
          Termination (as defined in Section 12).

     (d)  In the event there is a Change of Control at any time during the Term,
          then the acceleration of the vesting schedule of the One Million
          Options and the exercisibility of the One Million Options shall be
          governed by the Plan upon such Change of Control.

     (e)  The One Million Options shall expire on the earlier of ten years from
          the date of grant or the termination date set forth in the Stock
          Option Agreement after termination of Executive's employment with the
          Company.

     (f)  In the event the outstanding shares of common stock of the Company are
          changed into or exchanged for a different number or kind of shares or
          other securities of the Company or of another corporation by reason of
          merger, consolidation, other reorganization, reclassification,
          combination of shares, stock split-up or stock dividend, the One
          Million Options granted hereunder, the number of subject shares and
          the exercise price (and other terms herein relating thereto) shall be
          adjusted appropriately.

     6.  Additional Stock Options.  Executive shall be considered for additional
         ------------------------
stock option grants at least annually and any such additional grants shall be
determined by the Board of Directors.  In determining whether to award any
additional stock option grants, the Board of Directors shall consider, among
other things, Executive's performance in his capacity as CAO of the Company.

     7.  Benefits.  Executive shall be entitled to receive the following
         ---------
     benefits:

     (a)   Health care coverage equivalent to that provided to the Company's
          other executive officers.

          appropriate moving allowance, if applicable. The Company shall
          purchase a 2000 model of a recreational vehicle selected by the
          Executive.

     8.  Reimbursement for Expenses.  Executive shall be expected to incur
         --------------------------
various business expenses customarily incurred by persons holding like position,
including but not limited to traveling, entertainment and similar expenses, all
of which are to be incurred by Executive in the belief that they will benefit
the Company.  Subject to Company's policy regarding the reimbursement and non-
reimbursement of such expenses, Company shall reimburse Executive for such
expenses from time to time, at Executive's request, and Executive shall account
to Company for such expenses.

     9.  Protection of Company's Interests.

          not compete in any manner, directly or indirectly, whether as a
          principal, employee, consultant, agent, owner or otherwise, by Company
          or any affiliate thereof except that the foregoing will not prevent
          Executive from holding at any time less that 5% of the outstanding
          capital stock of any company (other than as part of a control group)
          whose stock is publicly traded.

     (b)  To the extent permitted by law, all rights worldwide with respect to
          any and all intellectual or other property of any nature produced,
          created or suggested by Executive during the Term of his employment or
          resulting from his service shall be deemed to be a work for hire and
          shall be the sole and exclusive property of Company. Executive agrees
          to execute, acknowledge and deliver to Company, at Company's request,
          such further documents as Company finds appropriate to evidence
          Company's rights in such property. Any confidential and/or proprietary
          information of Company or any affiliate thereof (including, without
          limitation, any information relating to the identities, capabilities,
          compensatory and contractual arrangements and/or general personnel
          data of employees of Company and its affiliates) shall not be used by
          Executive or disclosed or made available by Executive to any person
          except as required in the course of his employment by the Company, and
          upon expiration or earlier termination of the Term of this Agreement,
          Executive shall return to Company all such information that exists in
          written or other physical form (and all copies thereof under his
          control). Executive agrees to sign the Company's standard form of
          confidentiality agreement contemporaneously with the execution and
          delivery of this Agreement.

     10.  Termination.  In addition to any right to terminate Executive's
          -----------
     employment with the Company under Section 1 above:

     (a)  Company shall have the right to terminate Executive's employment with
          the Company under the following circumstances:

                                       4

          (i)    Upon death of Executive;

          (ii)   Upon notice from the Company to Executive in the event of an
          illness or other disability which has totally and permanently
          incapacitated him from performing his duties as Executive on a
          substantially full-time basis as described in the Company's long term
          disability plan;

          (iii)  For good cause immediately upon notice from Company.
          Termination by Company of Executive's employment for "Good Cause" as
          used in this Agreement shall mean actual fraud, or embezzlement, or
          intentional misconduct which has caused demonstrable and serious
          injury to the Company; or

          (iv)   Conviction of a felony or crime of moral turpitude which has
          caused serious injury to the Company.

     (b)  If Executive's employment is terminated pursuant to Section 10(a)(iii)
          or 10(a)(iv) above, Executive's rights and Company's obligations
          hereunder, and all unvested stock options granted in accordance with
          this Agreement which have not already vested shall forthwith terminate
          in their entirety, except that, notwithstanding the foregoing, (i) the
          expiration date of any Options which have already vested in accordance
          with this Agreement shall be ninety (90) days after the date of
          termination pursuant to Section 10(a).

     (c)  If Executive's employment is terminated pursuant to this Section 10,
          no Termination Payment (as defined in Section 12) shall be payable (it
          being understood that, notwithstanding anything to the contrary
          contained herein, the Company shall have the right to terminate
          Executive's employment for any other reason, subject to Executive's
          rights under Section 12).

     11.  Termination By Executive.  Prior to the expiration of the Term,
          ------------------------
Executive shall have the right to terminate his employment under this Agreement
upon 30 days notice to Company given within 60 days following the occurrence of
any of the following events, provided that Company shall have 20 days after the
date such notice has been given to Company in which to cure the conduct or cause
specified in such notice:

     (a)  Executive is not elected or retained in accordance with Section 2 as
          CAO (reporting to Company's CEO);

     (b)  There is a significant change in the nature or scope of the
          Executive's authority, powers, functions, duties or responsibilities
          which are inconsistent with the authority, powers, functions, duties
          or responsibilities of a CAO;

     (c)  Company shall fail to issue stock pursuant to the One Million Options
          provided

                                       5
<PAGE>

          for herein in accordance with the terms hereof or shall reduce his
          salary, or the Company shall fail to make any grant of options or
          compensation payment required hereunder;

     (d)  A Change of Control shall occur; and

     (e)  Any material breach of this Agreement by the Company including naming
          the Executive's principal office outside of the New York/ New Jersey/
          Connecticut tri-state area.

     12.  Termination Payment.  If a Non-Fault Termination (as defined below) of
          -------------------
Executive's employment with Company shall occur other than by means of the death
or disability of Executive, Executive shall be entitled to receive a lump sum
payment equal to the sum of one times the sum of Executive's then annual base
salary and bonus (provided, however, that in no event shall the annual bonus for
this purpose be less than $500,000) ("Termination Payment").  The Termination
Payment shall be made to Executive not later than 30 days after the date of such
Non-Fault Termination.  "Non-Fault Termination" shall mean Executive's
employment with Company shall be terminated (i) by the Company without cause,
(ii) by reason of death or total and permanent disability pursuant to Section
10(a)(i) or (ii) hereof, or (iii) Executive shall validly terminate his
employment pursuant to Section 11 hereof.  A voluntary termination of employment
by Executive (unless validly made pursuant to Section 11) shall not be a Non-
Fault Termination.  Except for Executive's rights under Sections 3 (b) and 5
(c), which shall remain in full force and effect after any Non-Fault Termination
of this Agreement, and for the acceleration of the vesting of the One Million
Options, the Termination Payment described Section 12 shall be Executive's sole
and exclusive remedy under this Agreement in the event of a Non-Fault
Termination.

     13.  Assignment.  Company may assign this Agreement or all or any part of
          ----------
its rights hereunder to any entity that succeeds to all or substantially all of
Company's assets or that holds, directly or indirectly, all or substantially all
of the capital stock of the Company or that is otherwise a successor in interest
to Company generally, and this Agreement shall inure to the benefit of, and be
binding upon, such assignee or successor in interest.  This Agreement is
personal to Executive and Executive may not, without the express written
permission of Company, assign or pledge any rights or obligations hereunder to
any person, firm, corporation or other entity.

     14.  No Conflict With Prior Agreements.  Executive represents and warrants
          ---------------------------------
to Company that, to the best of his personal knowledge and belief, neither the
execution and delivery of this Agreement, his commencement of employment
hereunder nor the performance of his duties hereunder conflicts with any
contractual commitment on his part to any third party or violates or interferes
with any rights of any third party.

     15.  Key Man Insurance.  Company shall have the right to secure, in its own
          -----------------
name or otherwise, and at its own expense, life, disability, accident or other
insurance covering Executive

                                       6
<PAGE>

and Executive shall have no right, title or interest in or to such insurance.
Executive shall assist Company in procuring such insurance by submitting to
reasonable examinations and signing such applications and other instruments as
may be required by the insurance carriers to which application is made for any
such insurance.

     16. Post-Termination Obligation.  After the expiration or earlier
         ---------------------------
termination of the Executive's employment hereunder for any reason whatsoever,
Executive shall not either alone or jointly, with or on behalf of others, either
directly or indirectly, expressly or impliedly, whether as principal, partner,
agent, shareholder, director, employee, consultant or otherwise, at any time
during a period of two years following such expiration or termination, solicit
in any manner whatsoever the employment or engagement of, either for his own
account or for any other person, firm, company or other entity, any person who
is employed by Company or any affiliated entity, whether or not such person
would commit any breach of his contract of employment by reason of his leaving
the service of Company or any affiliated entity.

     17. Reimbursement of Legal Expenses.   The Company agrees to reimburse
         --------------------------------
Executive for his reasonable out-of-pocket legal expenses and costs incurred in
connection with the negotiation and preparation of this Agreement.

     18. Entire Agreement, Amendment, Waiver, Etc.
         ----------------------------------------

     (a)  This Agreement supersedes all prior and/or contemporaneous agreements
          and/or statements, whether written or oral, concerning the terms of
          Executive's employment, and no amendment or modification of this
          Agreement shall be binding unless set forth in writing signed by
          Company and Executive.  No waiver by either party of any breach by the
          other party of any provision or condition of this Agreement shall be
          effective unless in writing and signed by the party effecting the
          waiver, and no such waiver shall be deemed a waiver of any similar or
          dissimilar provision or condition at the same or any prior or
          subsequent time.

     (b)  All payments required to be made to Executive hereunder, whether
          during the term of his employment hereunder or otherwise, shall be
          subject to all applicable federal, state and local tax withholding
          laws.

     (c)  This Agreement shall be governed by and construed in accordance with
          the laws of the State of California.  In the event of any controversy
          or claim by either party hereunder, the prevailing party in any final
          and legally binding adjudication (as to which all periods for the
          filing of any appeal have expired) with respect to such controversy or
          claim shall be entitled to reimbursement from the losing party for
          reasonable attorney's fees and costs and for all other reasonable
          expenses of such adjudication.

     19.  Notices.  All notices that either party is required or may desire to
          -------
give the other shall be in writing and shall be effective (i) upon personal
delivery or (ii) three business days after

American Arbitration Association then in effect and judgement upon any award
pursuant to such arbitration may be enforced in any court having jurisdiction
thereof, provided each of the parties to this Agreement will appoint one person
as an arbitrator to hear and determine the dispute, and if they are unable to

Agreement.  Subject to Section 18(c), the expenses of the arbitration
proceedings concluded pursuant to this paragraph will be borne by the parties in

     21.  Certain Additional Payments by the Company.  Anything in this
          ------------------------------------------
Agreement to the contrary notwithstanding, in the event it shall be determined
that any payment, award, benefit or distribution by the Company to or for the
benefit of the Executive would be subject to the excise tax imposed by Section
4999 of the Internal Revenue Code or any corresponding provisions of state or
local tax laws as a result of payment upon a change of control, or any interest
or penalties are incurred by the Executive with respect to such excise tax (such
excise tax, together with any such interest and penalties, are hereinafter
collectively referred to as the "Excise Tax"), then the Executive shall be
entitled to receive an additional payment (a "Gross-Up Payment") in an amount
such that after payment by the Executive of all taxes (including any interest or
penalties imposed with respect to such taxes) imposed upon the Gross-Up Payment,
the Executive retains an amount of the Gross-Up Payment equal to the Excise Tax
imposed upon the payments.
