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

                              INDEMNITY AGREEMENT
                              -------------------

     This Agreement is made as of and effective the 1st day of March, 2000
("Agreement"), by and between GlobeNet Communications Group Limited, a Bermuda
corporation ("Company"), and Jorge L. Escalona of Morristown, New Jersey, USA
("Indemnitee"):

     RECITALS:
     --------

     A.  Highly competent persons are becoming more reluctant to serve publicly-
held corporations as officers, counsel or other key employees or in other
capacities unless they are provided with adequate protection through insurance
or adequate indemnification against inordinate risks of claims and actions
against them arising out of their service to and activities on behalf of the
corporation.

     B.  The increasing difficulties of obtaining adequate insurance and the
uncertainties relating to indemnification may impair the ability of the Company
to continue to attract and retain such persons.

     C.  The Board of Directors of the Company (the "Board") has determined that
the potential inability to attract and retain such persons is detrimental to the
best interest of the Company's stockholders and that the Company should act to
assure such persons that there will be increased certainty of such protection in
the future.

     D.  It is reasonable, prudent and necessary for the Company contractually
to obligate itself to indemnify such persons to the fullest extent permitted by
the Company's Bye-Laws and the Companies Act 1981 of Bermuda, so that they will
serve or continue to serve the Company free from undue concern that they will
not be so indemnified.

     E.  Indemnitee is willing to serve, continue to serve and to take on
additional service for or on behalf of the Company on the condition that he be
so indemnified.

     AGREEMENT:
     ---------

     NOW, THEREFORE, in consideration of the premises and the covenants
contained herein, the Company and Indemnitee do hereby covenant and agree as
follows:

     1.   Services by Indemnitee.  Indemnitee agrees to serve as an officer,
          ----------------------
employee, agent or fiduciary of the Company and/or an affiliate thereof, and may
at the request of the Company, agree to serve as a director, officer, employee,
agent or fiduciary of another corporation, partnership, joint venture, trust or
other enterprise. Indemnitee may at any time and for any reason resign from such
position (subject to any other contractual obligation or any obligation imposed
by operation of law), in which event the Company shall have no obligation under
this Agreement to continue Indemnitee in any such position.
<PAGE>

     2.   Indemnification - General.  The Company shall indemnify and advance
          -------------------------
Expenses (as hereinafter defined) to Indemnitee as provided in this Agreement
and to the fullest extent permitted by the Company's Bye-Laws and the Companies
Act 1981 of Bermuda in effect on the date hereof and to such greater extent as
applicable law may thereafter from time to time permit. The rights of Indemnitee
provided under the preceding sentence shall include, but shall not be limited
to, the rights set forth in the other Sections of the Agreement. This Agreement
shall also apply to any claims brought against the Indemnitee which antedate the
date hereof, so long as Indemnitee was serving in a Corporate Status (as
hereinafter defined) with respect to any such claims.

     3.   Proceedings Other Than Proceedings by or in the Right of the Company.
          --------------------------------------------------------------------
Indemnitee shall be entitled to the rights of indemnification provided in this
Section 3 if, by reason of his Corporate Status, he is, or is threatened to be
made, a party to any threatened, pending, or completed Proceeding (as
hereinafter defined), other than a Proceeding by or in the right of the Company.
Pursuant to this Section 3, Indemnitee shall be indemnified against Expenses,
judgments, penalties, fines and amounts paid in settlement actually and
reasonably incurred by him or on his behalf in connection with such Proceeding
or any claim, issue or matter therein, if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
Company, and, with respect to any criminal Proceeding, had no reasonable cause
to believe his conduct was unlawful.

     4.   Proceeding by or in the Right of the Company.  Indemnitee shall be
          --------------------------------------------
entitled to the rights of indemnification provided in this Section 4 if, by
reason of his Corporate Status, he is, or is threatened to be made, a party to
any threatened, pending or completed Proceeding brought by or in the right of
the Company to procure a judgment in its favor. Pursuant to this Section,
Indemnitee shall be indemnified against Expenses, judgments, penalties, fines
and amounts paid in settlement actually and reasonably incurred by him or on his
behalf in connection with such Proceeding if he acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the Company. Notwithstanding the foregoing, no indemnification against such
Expenses and against judgments, penalties, fines and amounts paid in settlement
shall be made in respect of any claim, issue or matter in any such Proceeding as
to which Indemnitee shall have been adjudged to be liable to the Company if
applicable law prohibits such indemnification; provided, however, that, if
applicable law so permits, indemnification against Expenses shall nevertheless
be made by the Company in such event if and only to the extent that the court in
which such Proceeding shall have been brought or is pending, shall determine.

     5.   Indemnification for Expenses of a Party Who is Wholly or Partly
          ---------------------------------------------------------------
Successful. Notwithstanding any other provision of this Agreement, to the extent
----------
that Indemnitee is, by reason of his Corporate Status, a party to and is
successful, on the merits or otherwise, in any Proceeding, he shall be
indemnified against all Expenses actually and reasonably incurred by him or on
his behalf in connection therewith. If Indemnitee is not wholly successful in
such Proceeding but is successful, on the merits or otherwise, as to one or more
but less than all claims, issues or matters in such Proceeding, the Company
shall indemnify Indemnitee against all Expenses actually and reasonably incurred
by him or on his behalf in connection with each successfully resolved claim,
issue or matter. If Indemnitee is not successful with respect to a claim, issue
or matter, Indemnitee's right to indemnification for Expenses with regard to
such claim, issue or matter shall be governed by Sections 3 and 4 of this
Agreement. For purposes of this Section and without limitation, the

                                       2
<PAGE>

termination of any claim, issue or matter in such a Proceeding by dismissal,
with or without prejudice, shall be deemed to be a successful result as to such
claim, issue or matter.

     6.   Indemnification for Expenses of a Witness.  Notwithstanding any other
          -----------------------------------------
provision of this Agreement, to the extent that Indemnitee is or is threatened
to be made, by reason of his Corporate Status, a witness in any Proceeding, he
shall be indemnified against all Expenses actually and reasonably incurred by
him or on his behalf in connection therewith.

     7.   Advancement of Expenses.  The Company shall advance all reasonable
          -----------------------
Expenses incurred by or on behalf of Indemnitee in connection with any
Proceeding within twenty days after the receipt by the Company of a statement or
statements from Indemnitee requesting such advance or advances from time to
time, whether prior to or after final disposition of such Proceeding. Such
statements shall reasonably evidence the Expenses incurred by Indemnitee and
shall include or be preceded or accompanied by an undertaking by or on behalf of
Indemnitee to repay any Expenses advanced if it shall ultimately be determined
that Indemnitee is not entitled to be indemnified against such Expenses.

     8.   Procedure for Determination of Entitlement to Indemnification.
          -------------------------------------------------------------

          (a)  To obtain indemnification against this Agreement, Indemnitee
shall submit to the Company a written request, including therein or therewith
such documentation and information as is reasonably available to Indemnitee and
is reasonably necessary to determine whether and to what extent Indemnitee is
entitled to indemnification. The Secretary of the Company shall, promptly upon
receipt of such a request for indemnification, advise the Board of Directors in
writing that Indemnitee has requested indemnification.

          (b)  Upon written request by Indemnitee for indemnification pursuant
to the first sentence of Section 8(a) hereof, a determination, if required by
applicable law, with respect to Indemnitee's entitlement thereto shall be made
in the specific case: (i) if a Change in Control (as hereinafter defined) shall
have occurred, by Independent Counsel (as hereinafter defined) (unless
Indemnitee shall request that such determination be made by the Board of
Directors or the stockholders, in which case by the person or persons or in the
manner provided for in clauses (ii) or (iii) of this Section 8(b)) in a written
opinion to the Board of Directors, a copy of which shall be delivered to
Indemnitee; (ii) if a Change of Control shall not have occurred, (A) by the
Board of Directors by a majority vote of a quorum consisting of Disinterested
Directors (as hereinafter defined), or (B) if a quorum of the Board of Directors
consisting of Disinterested Directors is not obtainable or, even if obtainable,
if such quorum of Disinterested Directors so directs, by Independent Counsel in
a written opinion to the Board of Directors, a copy of which shall be delivered
to Indemnitee or (C) by the stockholders of the Company; or (iii) as provided in
Section 9(b) of this Agreement; and, if it is so determined that Indemnitee is
entitled to indemnification, payment to Indemnitee shall be made within ten (10)
days after such determination. Indemnitee shall cooperate with the person,
persons or entity making such determination with respect to Indemnitee's
entitlement to indemnification, including providing to such person, persons or
entity upon reasonable advance request any documentation or information which is
not privileged or otherwise protected from disclosure and which is reasonably
available to Indemnitee and reasonably necessary to such determination. Any
costs or expenses (including attorneys' fees and disbursements) incurred by
Indemnitee in so cooperating with the person, persons or entity making

                                       3
<PAGE>

such determination shall be borne by the Company (irrespective of the
determination as to Indemnitee's entitlement to indemnification) and the Company
hereby indemnifies and agrees to hold Indemnitee harmless therefrom.

          (c)  In the event the determination of entitlement to indemnification
is to be made by Independent Counsel pursuant to Section 8(b) hereof, the
Independent Counsel shall be selected as provided in this Section 8(c). If a
Change of Control shall not have occurred, the Independent Counsel shall be
selected by the Board of Directors, and the Company shall give written notice to
Indemnitee advising her of the identity of the Independent Counsel so selected.
If a Change of Control shall have occurred, the Independent Counsel shall be
selected by Indemnitee (unless Indemnitee shall request that such selection be
made by the Board of Directors, in which event the preceding sentence shall
apply), and Indemnitee shall give written notice to the Company advising it of
the identity of the Independent Counsel so selected. In either event, Indemnitee
or the Company, as the case may be, may, within seven (7) days after such
written notice of selection shall have been given, deliver to the Company or to
Indemnitee, as the case may be, a written objection to such selection. Such
objection may be asserted only on the ground that the Independent Counsel so
selected does not meet the requirements of "Independent Counsel" as defined in
Section 17 of this Agreement, and the objection shall set forth with
particularity the factual basis of such assertion. If such written objection is
made, the Independent Counsel so selected may not serve as Independent Counsel
unless and until a court has determined that such objection is without merit.
If, within twenty (20) days after submission by Indemnitee of a written request
for indemnification pursuant to Section 8(a) hereof, no Independent Counsel
shall have been selected and not objected to, either the Company or Indemnitee
may petition the court of competent jurisdiction for resolution of any objection
which shall have been made by the Company or Indemnitee to the other's selection
of Independent Counsel and/or for the appointment as Independent Counsel of a
person selected by the Court or by such other person as the Court shall
designate, and the person with respect to whom an objection is so resolved or
the person so appointed shall act as Independent Counsel under Section 8(b)
hereof. The Company shall pay any and all reasonable fees and expenses of
Independent Counsel incurred by such Independent Counsel in connection with
acting pursuant to Section 8(b) hereof, and the Company shall pay all reasonable
fees and expenses incident to the procedures of this Section 8(c), regardless of
the manner in which such Independent Counsel was selected or appointed. Upon the
due commencement of any judicial proceeding or arbitration pursuant to Section
10(a)(iii) of this Agreement, Independent Counsel shall be discharged and
relieved of any further responsibility in such capacity (subject to the
applicable standards of professional conduct then prevailing).

     9.   Presumptions and Effect of Certain Proceedings.
          ----------------------------------------------

          (a)  If a Change of Control shall have occurred, in making a
determination with respect to entitlement to indemnification hereunder, the
person, persons or entity making such determination shall presume that
Indemnitee is entitled to indemnification under this Agreement if Indemnitee has
submitted a request for indemnification in accordance with Section 8(a) of this
Agreement, and the Company shall have the burden of proof to overcome that
presumption in connection with the making by any person, persons or entity of
any determination contrary to that presumption.

                                       4
<PAGE>

          (b)  If the person, persons or entity empowered or selected under
Section 8 of this Agreement to determine whether Indemnitee is entitled to
indemnification shall not have made a determination within sixty (60) days after
receipt by the Company of the request therefor, then requisite determination of
entitlement to indemnification shall be deemed to have been made and Indemnitee
shall be entitled to such indemnification, absent (i) a misstatement by
Indemnitee of a material fact, or an omission of a material fact necessary to
make Indemnitee's statement not materially misleading, in connection with the
request for indemnification, or (ii) a prohibition of such indemnification under
applicable law; provided, however, that such sixty (60) day period may be
extended for a reasonable time, not to exceed an additional thirty (30) days, if
the person, persons or entity making the determination with respect to
entitlement to indemnification in good faith requires such additional time for
the obtaining or evaluating of documentation and/or information relating
thereto; and provided, further, that the foregoing provisions of this Section
9(b) shall not apply (i) if the determination of entitlement to indemnification
is to be made by the stockholders pursuant to Section 8(b) of this Agreement and
if (A) within fifteen (15) days after receipt by the Company of the request for
such determination the Board of Directors has resolved to submit such
determination to the stockholders for their consideration at an annual meeting
thereof to be held within seventy-five (75) days after such receipt and such
determination is made at such meeting, or (B) a special meeting of stockholders
is called within fifteen (15) days after such receipt for the purpose of making
such determination, such meeting is held for such purpose within sixty (60) days
after having been so called and such determination is made at such meeting, or
(ii) if the determination of entitlement to indemnification is to be made by
Independent Counsel pursuant to Section 8(b) of this Agreement.

          (c)  The termination of any Proceeding or of any claim, issue or
matter therein, by judgment, order, settlement or conviction, or upon a plea of
nolo contendere or its equivalent, shall not (except as otherwise expressly
provided in this Agreement) of itself adversely affect the right of Indemnitee
to indemnification or create a presumption that Indemnitee did not act in good
faith and in a manner which he reasonably believed to be in or not opposed to
the best interests of the Company or, with respect to any criminal Proceeding,
that Indemnitee had reasonable cause to believe that his conduct was unlawful.

     10.  Remedies of Indemnitee.
          ----------------------

          (a)  In the event that (i) a determination is made pursuant to Section
8 of this Agreement that Indemnitee is not entitled to indemnification under
this Agreement, (ii) advancement of Expenses is not timely made pursuant to
Section 7 of this Agreement, (iii) the determination of entitlement to
indemnification is to be made by Independent Counsel pursuant to Section 8(b) of
this Agreement and such determination shall not have been made and delivered in
a written opinion within ninety (90) days after receipt by the Company of the
request for indemnification, or (iv) payment of indemnification is not made
pursuant to Section 6 of this Agreement within ten (10) days after receipt by
the Company of a written request therefor, or (v) payment of indemnification is
not made within ten (10) days after a determination has been made that
Indemnitee is entitled to indemnification or such determination is deemed to
have been made pursuant to Section 8 or 9 of this Agreement, Indemnitee shall be
entitled to an adjudication in an appropriate court in Bermuda, or in any other
court of competent jurisdiction, of his entitlement to such indemnification or
advancement of Expenses. Alternatively, Indemnitee, at his option, may seek an
award in arbitration to be conducted by a single arbitrator in Hamilton, Bermuda
pursuant to the Commercial Arbitration

                                       5
<PAGE>

Rules of the American Arbitration Association. Indemnitee shall commence such
proceeding seeking an adjudication or an award in arbitration within one hundred
eighty (180) days following the date on which Indemnitee first has the right to
commence such proceeding pursuant to this Section 10(a). The Company shall not
oppose Indemnitee's right to seek any such adjudication or award in arbitration.

          (b)  In the event that a determination shall have been made pursuant
to Section 8 of this Agreement that Indemnitee is not entitled to
indemnification, any judicial proceeding or arbitration commenced pursuant to
this Section 10 shall be conducted in all respects as a de novo trial, or
arbitration, on the merits that Indemnitee shall not be prejudiced by reason of
that adverse determination. If a Change of Control shall have occurred, in any
judicial proceeding or arbitration commenced pursuant to this Section 10, the
Company shall have the burden of proving that Indemnitee is not entitled to
indemnification or advancement of Expenses, as the case may be.

          (c)  If a determination shall have been made or deemed to have been
made pursuant to Section 8 or 9 of this Agreement that Indemnitee is entitled to
indemnification, the Company shall be bound by such determination in any
judicial proceeding or arbitration commenced pursuant to this Section 10, absent
(i) a misstatement by Indemnitee of a material fact, or an omission of a
material fact necessary to make Indemnitee's statement not materially
misleading, in connection with the request for indemnification, or (ii) a
prohibition of such indemnification under applicable law.

          (d)  The Company shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section 10 that the
procedures and presumptions of this Agreement are not valid, binding and
enforceable and shall stipulate in any such court or before any such arbitrator
that the Company is bound by all the provisions of this Agreement.

          (e)  In the event that Indemnitee, pursuant to this Section 10, seeks
a judicial adjudication of or an award in arbitration to enforce her rights
under, or to recover damages for breach of, this Agreement, Indemnitee shall be
entitled to recover from the Company, and shall be indemnified by the Company
against, any and all expenses (of the types described in the definition of
Expenses in Section 17 of this Agreement) actually and reasonably incurred by
her in such judicial adjudication or arbitration, but only if he prevails
therein. If it shall be determined in said judicial adjudication or arbitration
that Indemnitee is entitled to receive part but not all of the indemnification
or advancement of expenses sought, the expenses incurred by Indemnitee in
connection with such judicial adjudication or arbitration shall be appropriately
prorated.

     11.  Non-Exclusivity; Survival of Rights; Insurance; Subrogation.
          -----------------------------------------------------------

          (a)  The rights of indemnification and to receive advancement of
Expenses as provided by this Agreement shall not be deemed exclusive of any
other rights to which Indemnitee may at any time be entitled under applicable
law, the Company's Memorandum of Association, Bye-Laws, any agreement, a vote of
stockholders or a resolution of directors, or otherwise. No amendment,
alteration or repeal of this Agreement or any provision hereof shall be
effective as to any Indemnitee with respect to any action taken or omitted by
such Indemnitee in his Corporate Status prior to such amendment, alteration or
repeal.

                                       6
<PAGE>

          (b)  To the extent that the Company maintains an insurance policy or
policies providing liability insurance for directors, officers, employees,
agents or fiduciaries of the Company or of any other corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise which such
person serves at the request of the Company, 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 such director, officer, employee or agent
under such policy or policies.

          (c)  In the event of any 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 take all
action necessary to secure such rights, including execution of such documents as
are necessary to enable the Company to bring suit to enforce such rights.

          (d)  The Company shall not be liable under this Agreement to make any
payment of amounts otherwise indemnifiable hereunder if and to the extent that
Indemnitee has otherwise actually received such payment under any insurance
policy, contract, agreement or otherwise.

     12.  Duration of Agreement.  This Agreement shall continue until and
          ---------------------
terminate upon the later of: (a) ten (10) years after the date that Indemnitee
shall have ceased to serve as an officer, employee, agent or fiduciary of the
Company or a director, officer, employee, agent or fiduciary of any other
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise which Indemnitee served at the request of the Company; or (b) the
final termination of all pending Proceedings in respect of which Indemnitee is
granted rights of indemnification or advancement of expenses hereunder and of
any Proceeding commenced by Indemnitee pursuant to Section 10 of this Agreement
relating thereto. This Agreement shall be binding upon the Company and its
successors and assigns and shall inure to the benefit of Indemnitee and his
heirs, executors and administrators.

     13.  Severability.  If any provision or provisions of this Agreement shall
          ------------
be held to be invalid, illegal or unenforceable for any reason whatsoever: (a)
the validity, legality and enforceability of the remaining provisions of this
Agreement (including without limitation, each portion of any Section of this
Agreement containing any such provision held to be invalid, illegal or
unenforceable, that is not itself invalid, illegal or unenforceable) shall not
in any way be affected or impaired thereby; and (b) to the fullest extent
possible, the provisions of this Agreement (including, without limitation, each
portion of any Section of this Agreement containing any such provision held to
be invalid, illegal or unenforceable, that is not itself invalid, illegal or
unenforceable) shall be construed so as to give effect to the intent manifested
by the provision held invalid, illegal or unenforceable.

     14.  Exception to Right of Indemnification or Advancement of Expenses.
          ----------------------------------------------------------------
Notwithstanding any other provision of this Agreement, Indemnitee shall not be
entitled to indemnification or advancement of Expenses under this Agreement with
respect to any Proceeding, or any claim therein, brought or made by him against
the Company.

     15.  Identical Counterparts.  This Agreement may be executed in one or more
          ----------------------
counterparts, each of which shall for all purposes be deemed to be an original
but all of which together shall constitute one and the same Agreement.  Only one
such counterpart signed by the party against whom enforceability is sought needs
to be produced to evidence the existence of this Agreement.
