                              EMPLOYMENT AGREEMENT
                           DATED AS OF APRIL 1, 1998

                                      AND
                                JOHN M. SCANLON

     JOHN M. SCANLON ("Executive") and GLOBAL CROSSING LTD., a Cayman Island
("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 April 1, 1998, for a
two-year term ending March 31, 2000, and continue thereafter for successive
two-year terms, unless either Company or Executive gives notice to the other
at least three (3) months in advance of the expiration of the current two-year
term that it wishes to terminate this Agreement, in which event this Agreement
shall terminate as of the end of such current two-year term, unless earlier
terminated as hereinafter provided.

     2.   Title and Duties.  During the Term, Executive shall be employed by
Company as its Chief Executive Officer ("CEO") reporting to Lodwrick Cook and
Gary Winnick, Co-Chairmen of the Board of Directors 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, managing his personal
passive investments. Executive shall perform such duties, which shall not be
inconsistent with his position as CEO of Company, as are assigned to him from
time to time by the Co-Chairman of the Board of Directors of Company, and any
other duties undertaken or accepted by Executive. Company agrees to use its
best efforts to cause Executive to be elected to the Board of Directors of
Company (or its successor in interest), when a seat on the Board becomes
available, and to nominate Executive as a member of the

<PAGE>   2

management slate at such annual meeting of stockholders during his employment
hereunder at which Executive's director class comes up for election. Executive
agrees to serve on the Board if elected.

     3.   Salary. Executive shall receive a salary of $600,000 per annum during
the first two (2) years of the Term. Salary payments shall be made in equal
installments in accordance with Company's then prevailing payoff policy. No
later than three (3) months prior to the expiration of any two-year term.
Company shall notify Executive of the proposed annual salary and minimum bonus
for the next ensuing two-year term, which shall in no event be less than
Executive's then current annual salary and minimum bonus, and which shall become
the salary for such, ensuing two-year term, unless the Agreement is terminated
by Executive as provided in Section 1.

     4.   Bonus. 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 $400,000 for any year during the Term.

     5.   Stock Options. Executive shall be granted stock options ("Options") to
purchase an aggregate of One Million Two Hundred Thousand (1,200,000) shares of
common stock of Company. The Options shall be granted in accordance with, and
subject to, the following:

     (a)  The exercise price of Options shall be equal to Two Dollars and Fifty
          Cents ($2.50) per share, such option price representing the current
          fair market of the Company's common stock.

     (b)  Executive's right to purchase 1,200,000 shares of the Company's common
          stock shall vest in such shares according to the following schedule:

</TABLE>

     provided, however, that, notwithstanding the foregoing, any portion of
     Options scheduled to vest on a scheduled vesting date shall not vest on
     such scheduled vesting date (or or any time thereafter) if Executive's
     employment by Company pursuant to this Agreement shall have terminated
     other than as a result of a Change of Control (as defined in the Company's
     Stock Option Plan ([the "Plan"]).

(c)  In the event there is a Change of Control at any time during the Term, then
     the acceleration of the vesting schedule of Options and the exercise
     ability of the Options shall be governed by Company policy upon such Change
     of Control.

(d)  The Options shall expire on the earlier of ten years from the date of grant
     or the termination date set forth in the Plan after termination of
     Executive's employment with Company.

(e)  In the event a Public Offering (as hereunder defined) or reasonably
     equivalent opportunity to liquidate stock does not occur within three (3)
     years of the date hereof, Executive shall have the right, for a period of
     six (6) months thereafter exercisable on ten (10) days written notice to
     Company ("Put Period"), to



                                      -3-
<PAGE>   4



     require the Company to purchase from him 300,000 shares of common stock of
     the Company at a purchase price of Twenty Dollars ($20.00) per share. In
     such event, the Company shall pay to Executive the purchase price for such
     shares in cash within thirty (30) days of the effective date of such
     notice. The foregoing shall survive the termination of this Agreement,
     except if Executive is terminated under Section 9(a)(iii). If Executive is
     terminated under Section 9(a)(iii) during the Put Period, Executive's
     rights shall be subject to offset by any claim of Company for damages.

(f)  If Company proposes to register any of its stock or other securities under
     the Securities Act of 1933, as amended, in connection with the public
     offering of such securities solely for cash (other than a registration
     relating solely to the sale of securities to participants in a Company
     stock plan, or a registration on any form which does not include
     substantially the same information as would be required to be included in a
     registration statement covering the sale of the Shares or a SEC Rule 145
     Transaction), Company shall give prompt written notice to Executive of its
     intention to offset such a registration, including without limitation, any
     initial public offering ("Public Offering") and, provided that Company has
     received a written request for inclusion therein within fifteen (15) days
     after the date of reading of such notice, Company shall include in such
     registration all shares owned by Executive or which Executive has a vested
     option to purchase. Company shall pay all expenses incident to Company's
     performance of or compliance with this section, other than underwriters'
     discount and commissions, which are the sole responsibility of






                                      -4-
<PAGE>   5



          Executive, but including, without limitation, all registration and
          filing fees, fees and expenses of compliance with securities or blue
          sky laws, printing expenses, messenger and delivery expenses, and fees
          and disbursements of counsel for Company.

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

          following benefits and perquisites:

     (a)  Payment during each of the first two (2) years of the Term of an
          account which shall be "grossed up" by the maximum Federal and State
          individual income tax rate applicable to the year in which such
          payments are received by Executive in order to yield to the Executive
          a net after-tax amount of $138,000 per year payable in monthly
          installments during the Term. Such amount shall be in lieu of any
          other relocation allowance.

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

     (c)  Round trip first-class airfare between Los Angeles and Chicago during

          office in connection with all company travel.

to Company for such expenses.

     8.   Protection of Company's Interests.

          outstanding capital stock of any company whose stock is publicly
          traded.

     (b)  To the extent permitted by law, all rights worldwide with respect to

          and shall be the sole and exclusive property of Company. Executive

          request, such further documents as Company finds


                                      -6-
