         shall be released to or for the account of, or withdrawn by or for the
         account of, the Pledgor or any other Person except as expressly
         provided in this Pledge Agreement.

                  (b)      On the Closing Date, the Pledgor shall transfer, or
cause to be transferred, to the Trustee an amount equal to $86,549,914.84 by
depositing all such proceeds into the Cash Collateral Account.

                  (c)      As soon as possible after receipt of the amount
referred to in Section 2(b), (i) the Trustee shall apply such amount to purchase
the U.S. Government Obligations (in the name of the Trustee) listed on Schedule
I hereto, and cause the FaciliCom Securities Intermediary to credit such U.S.
Government Obligations to the Pledge Account as Collateral hereunder; and (ii)
the Trustee shall ensure that, on the Settlement Date, the FRBB credits in the
FRBB Account those U.S. Government Obligations being settled on such date.

                  (d)      The Trustee will, from time to time, reinvest the
proceeds of Collateral that may mature or be sold in such Collateral Investments
(in the name of the Trustee) as it may be directed in writing by the Pledgor,
and cause such Collateral Investments to be credited to the Pledge Account as
Collateral hereunder. Such proceeds that are not so reinvested in Collateral
Investments shall be deposited and held in the Cash Collateral Account.

                  SECTION 3.       Delivery of the Pledged Securities. (a) The
Pledged Securities shall be pledged and delivered to the Pledge Account and the
Trustee and the Trustee shall become the Entitlement Holder of a Security
Entitlement to the Pledged Securities through action by the



   12
                                                                               8

FaciliCom Securities Intermediary, as confirmed (in writing or electronically or
otherwise in accordance with standard industry practice) to the Trustee by the
FaciliCom Securities Intermediary (i) indicating by book-entry that the Pledged
Securities and all Security Entitlements thereto have been credited to the
Pledge Account, or (ii) acquiring the Pledged Securities and all Security
Entitlements thereto for the Trustee and accepting the same for credit to the
Pledge Account.

                  (b)      Prior to or concurrently with the execution and
delivery hereof and prior to the transfer to the Trustee of the Pledged
Securities (or acquisition by the Trustee of any Security Entitlement thereto),
as provided in subsection (a) of this Section 3, the Trustee and the FaciliCom
Securities Intermediary shall establish the Pledge Account on the books of the
FaciliCom Securities Intermediary as Securities Account segregated from all
other custodial or collateral accounts such account to be maintained either (i)
directly at its offices located at 225 Franklin Street, Boston Massachusetts

of the Pledged Securities to the Trustee (or the Trustee's acquisition of a

Intermediary by FRBB or another securities intermediary, the FaciliCom
Securities Intermediary shall make appropriate book entries indicating that the
Pledged Securities and/or such Security Entitlement have been credited to and
are held in the Pledge Account. Subject to the other terms and conditions of
this Pledge Agreement, all funds or other property held by the Trustee pursuant
to this Pledge Agreement shall be held in the Pledge Account or the Cash
Collateral Account subject (except as expressly provided in Section 6 hereof) to
the exclusive dominion and control (including, without limitation, Securities
Control) of the Trustee and exclusively for the benefit of the Trustee and for
the ratable benefit of the Holders of the Notes and segregated from all other
funds or other property otherwise held by the Trustee.

                  (c)      All Collateral shall be retained in the Pledge
Account or the Cash Collateral Account pending disbursement pursuant to the
terms hereof.

                  (d)      Concurrently with the execution and delivery of this
Pledge Agreement, the Trustee is delivering to the Pledgor and the Initial
Purchasers a duly executed certificate, in the form of Exhibit A hereto, of an
officer of the Trustee, confirming the Trustee's establishment and maintenance
of the Pledge Account with the FaciliCom Securities Intermediary and its receipt
and holding of the Pledge Securities or a Security Entitlement thereto and the
crediting of the Pledged Securities or such Security Entitlement to the Pledge
Account, all in accordance with this Pledge Agreement.

                  (e)      Concurrently with the execution and delivery of this
Pledge Agreement, the Pledgor is delivering to the Trustee an opinion of a
nationally recognized firm of independent public accountants, selected by the

   13
                                                                               9


                  (f)      Concurrently with the execution and delivery of this
Pledge Agreement, the Pledgor is delivering to the Trustee financing statements
in form acceptable for filing under the UCC of the State of New York,
Commonwealth of Massachusetts and the District of Columbia, covering the
Collateral described in this Pledge Agreement.

                  SECTION 4.        Delivery of Collateral Other than U.S.
Government Obligations. (a) Collateral consisting of cash will be deemed to be
delivered to the Trustee (such that the Trustee will have an enforceable lien
and security interest thereon and therein), when it has been (and for so long as
it shall remain) deposited in or credited to the Cash Collateral Account.

                  (b)      Collateral consisting of Cash Equivalents (other
than U.S. Government Obligations) will be deemed to be delivered to the Trustee
(such that the Trustee will have an enforceable lien and security interest
thereon and therein), when they have been (and for so long as they shall remain)
deposited in or credited to either Collateral Account.

                  (c)      Collateral consisting of Securities (other than U.S.
Government Obligations) will be deemed delivered to the Trustee when the
FaciliCom Securities Intermediary (A) shall indicate by book entry that such
Securities have been credited to the Pledge Account or (B) shall receive such
Security (or a Financial Asset based on such Security) for the Trustee, from or
at the direction of the Pledgor, and shall accept such Security (or such
Financial Asset) for credit to such Collateral Account;

                  (d)      Collateral consisting of Securities and represented
or evidenced by certificates or instruments, will be deemed delivered to the
Trustee when all such certificates or instruments representing or evidencing the
Collateral, including, without limitation, amounts invested as provided in
Section 5, shall be delivered to the FaciliCom Securities Intermediary and held
by or on behalf of the Trustee pursuant hereto and shall be in registered form
and specially indorsed to the Trustee by an effective indorsement, all in form
and substance sufficient to convey a valid security interest in such Collateral
to the Trustee or shall be credited to the Pledge Account.

                  SECTION 5.       Investing of Amounts in the Collateral
Accounts. If at any time, any amounts shall exist in the Collateral Accounts
uninvested, and if directed in writing by the Pledgor, the Trustee will, subject
to the provisions of Section 6 and Section 13, (a) invest such amounts on
deposit in the Collateral Accounts in such Cash Equivalents in the name of the
Trustee as the Pledgor may select and (b) invest interest paid on the Cash
Equivalents referred to in clause (a) above, and reinvest other proceeds of any
such Cash Equivalents that may mature or be sold, in each case in such Cash
Equivalents in the name of the Trustee, as the Pledgor may select and the
Trustee may approve (the Cash Equivalents referred to in clauses (a) and (b)
above, together with the Pledged Securities, being collectively referred to
herein as "Collateral Investments"); provided, however, that the amount in cash
and Pledged Securities on deposit in

   14
                                                                              10


the Collateral Accounts, collectively, at any time during the term of this
Pledge Agreement, must be sufficient to provide for the payment in full of the
remaining interest payments at such time on the Notes up to and including the
sixth scheduled interest payment. Except as otherwise provided in Sections 11
and 12, the Trustee shall not be liable for any loss in the investment or
reinvestment of amounts held in the Collateral Accounts.

                  SECTION 6.        Disbursements.  The Trustee shall hold the
Collateral in the Collateral Accounts and release the same, or a portion
thereof, only as follows:

                  (a)      At least one Business Day prior to the due date of
any of the first six scheduled interest payments on the Notes, the Pledgor may,
pursuant to written instructions executed by the Pledgor (an "Issuer Order"),
direct the Trustee to release from the Collateral Accounts and pay to the
Holders of the Notes proceeds sufficient to provide for payment in full of such
interest then due on the Notes; provided, however, that in the event Collateral
is required to be liquidated, the Pledgor will give the Trustee at least three
Business Days' notice. Upon receipt of an Issuer Order, the Trustee will take
any action necessary to provide for the payment of the interest on the Notes to
the Holders of the Notes in accordance with the payment provisions of the
Indenture from (and to the extent of) proceeds of the Collateral in the
Collateral Accounts. Nothing in this Section 6 shall affect the Trustee's rights
to apply the Collateral to the payments of amounts due on the Notes upon
acceleration thereof.

                  (b)      If the Pledgor makes any interest payment or portion
of an interest payment for which the Collateral is security from a source of
funds other than the Collateral Accounts ("Pledgor Funds"), the Pledgor may,
after payment in full of such interest payment or portion thereof from proceeds
of the Collateral or such Pledgor Funds or both, direct the Trustee by Issuer
Order to release to the Pledgor or to another party at the direction of the
Pledgor (the "Pledgor's Designee") proceeds from the Collateral Accounts in an
amount less than or equal to the amount of Pledgor Funds applied to such
interest payment. Upon receipt of such Issuer Order by the Trustee, the Trustee
shall pay over to the Pledgor or the Pledgor's Designee, as the case may be, the
requested amount from proceeds in the Collateral Accounts. Concurrently with any
release of funds to the Pledgor pursuant to this Section 6(b), the Pledgor shall
deliver to the Trustee a certificate signed by an officer of the Pledgor stating
that the Pledgor has made the interest payment from a source of funds other than
the Pledge Account, and that such release has been duly authorized by the
Pledgor and will not contravene any provision of applicable law or Certificate
of Incorporation or the By-laws of the Pledgor or any material agreement or
other material instrument binding upon the pledgor or any of its subsidiaries or
any judgment, order or decree of any governmental body, agency or court having
jurisdiction over the Pledgor or any of its subsidiaries or result in the
creation or imposition of any Lien on any assets of the Pledgor, except for the
security interest granted under the Pledge Agreement.

                  (c)      At least one Business Day prior to the due date of
any of the first six scheduled interest payments on the Notes, the Pledgor
covenants to give the Trustee (by Issuer


   15
                                                                              11


Order) notice as to whether payment of interest will be made pursuant to Section
6(a) or 6(b) and as to the respective amounts of interest that will be paid
pursuant to Section 6(a) or 6(b); provided, however, that, in the event
Collateral is required to be liquidated, the Pledgor will give the Trustee at
least three Business Days' notice. If no such notice is given, the Trustee will,
subject to Section 6(d), act pursuant to Section 6(a) as if it had received an
Issuer Order pursuant thereto for the payment in full of the interest then due.

                  (d)      The Trustee shall not be required to liquidate any
Collateral Investments in order to make any scheduled payment of interest or any
release hereunder unless instructed to do so by Issuer Order or pursuant to
Section 13 hereof.

                  (e)      Upon the Termination Date, the security interest in
the Collateral evidenced by this Pledge Agreement will automatically terminate
and be of no further force and effect and the Collateral, upon receipt by the
Trustee of an Issuer Order, shall promptly be paid over and transferred to the
Pledgor.

                  (f)      In the event that the Collateral held in the Pledge
Account exceeds 100% of the amount sufficient, in the opinion of a nationally
recognized firm of independent public accountants selected by the Pledgor, to
provide for payment in full of the first six scheduled interest payments due on
the Notes (or, in the event an interest payment or payments have been made, an
amount sufficient to provide for payment in full of all interest payments
remaining, up to and including the sixth scheduled interest payment), the
Trustee shall release to the Pledgor, at the Pledgor's written request,
accompanied by an opinion prepared by a nationally recognized firm of
independent public accountants, any such excess Collateral.

                  (g)      Upon the release of any Collateral from the Pledge
Account, in accordance with the terms of this Pledge Agreement, the security
interest evidenced by this Pledge Agreement in such released Collateral will
automatically terminate and be of no further force and effect.

                  (h)      Nothing contained in Section 1, Section 13, this
Section 6 or any other Provision of this Pledge Agreement shall (i) afford the
Pledgor any right to issue Entitlement Orders with respect to any Security
Entitlement to the Pledge Securities or Collateral Investments or any Securities
Account in which any such Security Entitlement may be carried, or otherwise
afford the Pledgor control of any such Security Entitlement or (ii) otherwise
give rise to any rights of the Pledgor with respect to the Collateral
Investments, any Security Entitlement thereto or any Securities Account in which
any such Security Entitlement may be carried, other than the Pledgor's rights
under this Pledge Agreement as the beneficial owner of Collateral pledged to and
subject to the exclusive dominion and control (including, without limitation,
Securities Control) (except as expressly provided in this Section 6) of the
Trustee in its capacity as such (and not as a Securities Intermediary). The
Pledgor acknowledges, confirms and agrees


   16
                                                                              12

that the Trustee holds a Security Entitlement to the Collateral Investments
solely as trustee for the Holders of the Notes and not as a Securities
Intermediary for the Pledgor.

                  SECTION 7.        Representations and Warranties.  The
Pledgor hereby represents and warrants, as of the date hereof, that:

                  (a)      The execution and delivery by the Pledgor of, and the
         performance by the Pledgor of its obligations under, this Pledge
         Agreement will not contravene any provision of applicable law or the
         Certificate of Incorporation or By-laws of the Pledgor or any material
         agreement or other material instrument binding upon the Pledgor or any
         of its subsidiaries or any judgment, order or decree of any
         governmental body, agency or court having jurisdiction over the Pledgor
         or any of its subsidiaries, or result in the creation or imposition of
         any Lien on any assets of the Pledgor, except for the security
         interests granted under this Pledge Agreement; no consent, approval,
         authorization or order of, or qualification with, any governmental body
         or agency is required (i) for the performance by the Pledgor of its
         obligations under this Pledge Agreement, (ii) for the pledge by the
         Pledgor of the Collateral pursuant to this Pledge Agreement or (iii)
         except for any such consents, approvals, authorizations or orders
         required to be obtained by the Trustee (or the Holders) for reasons
         other than the consummation of this transaction, for the exercise by
         the Trustee of the rights provided for in this Pledge Agreement or the
         remedies in respect of the Collateral pursuant to this Pledge
         Agreement.

                  (b)      The Pledgor is the beneficial owner of the
         Collateral, free and clear of any Lien or claims of any person or
         entity (except for the security interests granted under this Pledge
         Agreement). No financing statement covering the Pledgor's interest in
         the Collateral is on file in any public office other than the financing
         statements, if any, filed pursuant to this Pledge Agreement.

                  (c)      This Pledge Agreement has been duly authorized,
         validly executed and delivered by the Pledgor and (assuming the due
         authorization and valid execution and delivery of this Pledge Agreement
         by the Trustee and enforceability of the Pledge Agreement against the
         Trustee in accordance with its terms) constitutes a valid and binding
         agreement of the Pledgor, enforceable against the Pledgor in accordance
         with its terms, except as (i) the enforceability hereof may be limited
         by bankruptcy, insolvency, fraudulent conveyance, preference,
         reorganization, moratorium or similar laws now or hereafter in effect
         relating to or affecting the rights or remedies of creditors generally,
         (ii) the availability of equitable remedies may be limited by equitable
         principles of general applicability and the discretion of the court
         before which any proceeding therefor may be brought, (iii) the
         exculpation provisions and rights to indemnification hereunder may be
         limited by U.S. federal and state securities laws and public policy
         considerations

   17
                                                                              13


         and (iv) the waiver of rights and defenses contained in Section 13(b),
         Section 17.11 and Section 17.15 hereof may be limited by applicable
         law.

                  (d)      Upon the delivery to the Trustee of the Collateral
         in accordance with the procedures described in Section 3 and Section 4
         hereof, the pledge of and grant of a security interest in the
         Collateral securing the payment of the Obligations for the benefit of
         the Trustee and the Holders of the Notes will constitute a valid, first
         priority, perfected security interest in such Collateral (except, with
         respect to Proceeds, only to the extent permitted by Section 9-306 of
         the UCC), enforceable as such against all creditors of the Pledgor and
         any persons purporting to purchase any of the Collateral from the
         Pledgor, except in each case as enforcement may be affected by general
         equitable principles (whether considered in a proceeding in equity or
         at law) and other than as permitted by the Indenture.

                  (e)      There are no legal or governmental proceedings
         pending or, to the best of the Pledgor's knowledge, threatened to which
         the Pledgor or any of its subsidiaries is a party or to which any of
         the properties of the Pledgor or any of its subsidiaries is subject
         that would materially adversely affect the power or ability of the
         Pledgor to perform its obligations under this Pledge Agreement or to
         consummate the transactions contemplated hereby.

                  (f)      The pledge of the Collateral pursuant to this Pledge
         Agreement is not prohibited by law or governmental regulation
         (including, without limitation, Regulations G, T, U and X of the Board
         of Governors of the Federal Reserve System) applicable to the Pledgor.

                  (g)       No Event of Default (as defined herein) exists.

                  SECTION 8.        Further Assurances. The Pledgor will,
promptly upon the request by the Trustee (which request the Trustee may submit
at the direction of the Holders of a majority in aggregate principal amount of
the Notes then outstanding), execute and deliver or cause to be executed and
delivered, or use its reasonable best efforts to procure, all assignments,
instruments and other documents, all in form and substance reasonably
satisfactory to the Trustee, deliver any instruments to the Trustee and take any
other actions that are necessary or desirable to perfect, continue the
perfection of, or protect the first priority of the Trustee's security interest
in and to the Collateral, to protect the Collateral against the rights, claims
or interests of third persons (other than any such rights, claims or interests
created by or arising through the Trustee) or to effect the purposes of this
Pledge Agreement. The Pledgor also hereby authorizes the Trustee to file any
financing or continuation statements in the United States with respect to the
Collateral without the signature of the Pledgor (to the extent permitted by
applicable law). The Pledgor will promptly pay all reasonable costs incurred in
connection with



   18
                                                                              14


any of the foregoing within 45 days of receipt of an invoice therefor. The
Pledgor also agrees, whether or not requested by the Trustee, to use its
reasonable best efforts to perfect or continue the perfection of, or to protect
the first priority of, the Trustee's security interest in and to the Collateral,
and to protect the Collateral against the rights, claims or interests of third
persons (other than any such rights, claims or interests created by or arising
through the Trustee).

                  SECTION 9.        Covenants. The Pledgor covenants and agrees
with the Trustee and the Holders of the Notes that from and after the date of
this Pledge Agreement until the Termination Date:

                  (a)      that it will not (i) (and will not purport to) sell
         or otherwise dispose of, or grant any option or warrant with respect
         to, any of the Collateral nor (ii) create or permit to exist any Lien
         upon or with respect to any of the Collateral (except for the security
         interests granted under this Pledge Agreement and any Lien created by
         or arising through the Trustee) and at all times will be the sole
         beneficial owner of the Collateral; and

                  (b)      that it will not (i) enter into any agreement or
         understanding that restricts or inhibits or purports to restrict or
         inhibit the Trustee's rights or remedies hereunder, including, without
         limitation, the Trustee's right to sell or otherwise dispose of the
         Collateral or (ii) fail to pay or discharge any tax, assessment or levy
         of any nature with respect to the Collateral not later than five days
         prior to the date of any proposed sale under any judgment, writ or
         warrant of attachment with respect to the Collateral.

                  SECTION 10.       Power of Attorney. In addition to all of the
powers granted to the Trustee pursuant to the Indenture, subject to the terms of
this Pledge Agreement, the Pledgor hereby appoints and constitutes the Trustee
as the Pledgor's attorney-in-fact (with full power of substitution) to exercise
to the fullest extent permitted by law all of the following powers upon and at
any time after the occurrence and during the continuance of an Event of Default:
(a) collection of proceeds of any Collateral; (b) conveyance of any item of
Collateral to any purchaser thereof; (c) giving of any notices or recording of
any Liens under Section 3 hereof; and (d) paying or discharging taxes or Liens
levied or placed upon the Collateral, the legality or validity thereof and the
amounts necessary to discharge the same to be determined by the Trustee in its
sole reasonable discretion, and such payments made by the Trustee to become part
of the Obligations of the Pledgor to the Trustee, due and payable immediately
upon demand. The Trustee's authority under this Section 10 shall include,
without limitation, the authority to endorse and negotiate any checks or
instruments representing proceeds of Collateral in the name of the Pledgor,
execute and give receipt for any certificate of ownership or any document
constituting Collateral, transfer title to any item of Collateral, sign the
Pledgor's name on all financing statements (to the extent permitted by
applicable law) or any other documents deemed necessary or appropriate by the
Trustee in its reasonable discretion to preserve, protect or perfect the
security interest in the Collateral and to file the same, prepare, file and sign
the Pledgor's

   19
                                                                              15


name on any notice of Lien, and to take any other actions arising from or
incident to the powers granted to the Trustee in this Pledge Agreement. This
power of attorney is coupled with an interest and is irrevocable by the Pledgor.

                  SECTION 11.       No Assumption of Duties; Reasonable Care.
The rights and powers granted to the Trustee hereunder are being granted in
order to preserve and protect the security interest of the Trustee and the
Holders of the Notes in and to the Collateral granted hereby and shall not be
interpreted to, and shall not impose any duties on, the Trustee in connection
therewith other than those expressly provided herein or imposed under applicable
law. Except as provided by applicable law or by the Indenture, the Trustee shall
be deemed to have exercised reasonable care in the custody and preservation of
the Collateral in its possession if the Collateral is accorded treatment
substantially equal to that which the Trustee accords similar property held by
the Trustee for similar accounts, it being understood that the Trustee in its
capacity as such shall not have any responsibility for (a) ascertaining or
taking action with respect to calls, conversions, exchanges, maturities or other
matters relative to any Collateral, whether or not the Trustee has or is deemed
to have knowledge of such matters, (b) taking any necessary steps to preserve
rights against any parties with respect to any Collateral or (c) investing or
reinvesting any of the Collateral; provided, however, that nothing contained in
this Pledge Agreement shall relieve the Trustee of any responsibilities as a
securities intermediary under applicable law.

                  SECTION 12.       Indemnity. The Pledgor shall indemnify, hold
harmless and defend the Trustee and its directors and officers from and against
any and all claims, actions, obligations, liabilities and expenses, including
reasonable defense costs, reasonable investigative fees and costs, and
reasonable legal fees and damages arising from the Trustee's performance as
Trustee under this Pledge Agreement, except to the extent that such claim,
action, obligation, liability or expense is directly attributable to the bad
faith, gross negligence or wilful misconduct of such indemnified person. The
provisions of this Section 12 shall survive termination of this Pledge Agreement
and the resignation and removal of the Trustee.

                  SECTION 13.       Remedies upon Event of Default. If any Event
of Default under the Indenture or default hereunder (any such Event of Default
or default being referred to in this Pledge Agreement as an "Event of Default")
shall have occurred and be continuing:

                  (a)      The Trustee and the Holders of the Notes shall have,
         in addition to all other rights given by law or by this Pledge
         Agreement or the Indenture, all of the rights and remedies with respect
         to the Collateral of a secured party under the UCC in effect in the
         State of New York and the District of Columbia at that time. In
         addition, with respect to any Collateral that shall then be in or shall
         thereafter come into the possession or custody of the Trustee, the
         Trustee may and, at the direction of the Holders of a majority in
         aggregate principal amount of the Notes then outstanding, shall appoint
         a broker or

   20
                                                                              16


         other expert to sell or cause the same to be sold at any broker's board
         or at public or private sale, in one or more sales or lots, at such
         price or prices such broker or other expert may deem best, for cash or
         on credit or for future delivery, without assumption of any credit
         risk. The purchaser of any or all Collateral so sold shall thereafter
         hold the same absolutely, free from any claim, encumbrance or right of
         any kind whatsoever created by or through the Pledgor. Unless any of
         the Collateral threatens, in the reasonable judgment of the Trustee, to
         decline speedily in value, the Trustee will give the Pledgor reasonable
         notice of the time and place of any public sale thereof, or of the time
         after which any private sale or other intended disposition is to be
         made. Any sale of the Collateral conducted in conformity with
         reasonable commercial practices of banks, insurance companies,
         commercial finance companies, or other financial institutions disposing
         of property similar to the Collateral shall be deemed to be
         commercially reasonable. Any requirements of reasonable notice shall be
         met if such notice is mailed to the Pledgor as provided in Section 17.1
         hereof at least ten (10) days before the time of the sale or
         disposition. The Trustee or any Holder of Notes may, in its own name or
         in the name of a designee or nominee, buy any of the Collateral at any
         public sale and, if permitted by applicable law, at any private sale.
         All expenses (including court costs and reasonable attorneys' fees,
         expenses and disbursements) of, or incident to, the enforcement of any
         of the provisions hereof shall be recoverable from the proceeds of the
         sale or other disposition of the Collateral.

                  (b)      The Pledgor further agrees to use its reasonable best
         efforts to do or cause to be done all such other acts as may be
         necessary to make such sale or sales of all or any portion of the
         Collateral pursuant to this Section 13 valid and binding and in
         compliance with any and all other applicable requirements of law. The
         Pledgor further agrees that a breach of any of the covenants contained
         in this Section 13 will cause irreparable injury to the Trustee and the
         Holders of the Notes, that the Trustee and the Holders of the Notes
         have no adequate remedy at law in respect of such breach and, as a
         consequence, that each and every covenant contained in this Section 13
         shall be specifically enforceable against the Pledgor, and the Pledgor
         hereby waives and agrees not to assert any defenses against an action
         for specific performance of such covenants except for a defense that no
         Event of Default has occurred.

                  SECTION 14.       Expenses. The Pledgor will upon demand pay
to the Trustee the amount of any and all reasonable expenses, including, without
limitation, the reasonable fees, expenses and disbursements of its counsel,
experts and agents retained by the Trustee, that the Trustee may incur in
connection with (a) the review, negotiation and administration of this Pledge
Agreement, (b) the custody or preservation of, or the sale of, collection from,
or other realization upon, any of the Collateral, (c) the exercise or
enforcement of any of the rights of the Trustee and the Holders of the Notes
hereunder or (d) the failure by the Pledgor to perform or observe any of the
provisions hereof.


   21
                                                                              17


                  SECTION 15.       Security Interest Absolute.  All rights of
the Trustee and the Holders of the Notes and security interests hereunder, and
all obligations of the Pledgor hereunder, shall be absolute and unconditional
irrespective of:

                  (a)      any lack of validity or enforceability of the
         Indenture or any other agreement or instrument relating thereto;

                  (b)      any change in the time, manner or place of payment
         of, or in any other term of, all or any of the Obligations, or any
         other amendment or waiver of or any consent to any departure from the
         Indenture;

                  (c)      any exchange, surrender, release or non-perfection of
         any Liens on any other collateral for all or any of the Obligations; or

                  (d)      to the extent permitted by applicable law, any other
         circumstance which might otherwise constitute a defense available to,
         or a discharge of, the Pledgor in respect of the Obligations or of this
         Pledge Agreement.

                  SECTION 16.       FaciliCom Securities Intermediary's
Representations, Warranties and Covenants. The FaciliCom Securities Intermediary
represents and warrants that it is as of the date hereof, and it agrees that for
so long as it maintains the Collateral Accounts and acts as the Securities
Intermediary pursuant to this Pledge Agreement it shall be a Securities
Intermediary and a FRBB Member. In furtherance of the foregoing the FaciliCom
Securities Intermediary hereby:

         Intermediary undertakes to treat the Trustee as entitled to exercise
         rights that comprise (and entitled to the benefits of) such Financial
         Assets, and entitled to exercise the rights of an Entitlement Holder in
         the manner contemplated by the UCC;

                  (d)      hereby represents that it has not granted, and
         covenants that so long as it acts as a Securities Intermediary
         hereunder it shall not grant, control (including without

   22
                                                                              18

         credited to any Collateral Account from time to time to any other
         Person other than the Trustee.

                  (e)      covenants that in its capacity as FaciliCom
         Securities Intermediary hereunder and with respect to the Collateral
         Accounts, it shall not take any action inconsistent with, and

         Pledge Account shall be treated as a Financial Asset;

                  (g)      agrees that any item of Collateral credited to any
         Collateral Account shall not be subject to any security interest, Lien
         or right of set-off in favor of the FaciliCom Securities Intermediary,
         except as may be expressly permitted under the Indenture (and the
         FaciliCom Securities Intermediary shall take such actions as shall be
         necessary and appropriate to cause such Collateral to remain free of
         any Lien or security interest of any underlying Securities Intermediary
         through which the FaciliCom Securities Intermediary holds such
         Collateral or any Security Entitlement thereto);

                  (h)      agrees, so long as it serves as FaciliCom Securities
         Intermediary pursuant to this Pledge Agreement, to maintain the
         Collateral Accounts and maintain appropriate books and records in
         respect thereof in accordance with its usual procedures and subject to

                  17.2     No Adverse Interpretation of Other Agreements. This
Pledge Agreement may not be used to interpret another pledge, security or debt
agreement of the Pledgor or any subsidiary thereof. No such pledge, security or
debt agreement (other than the Indenture) may be used to interpret this Pledge
Agreement.

                  17.3     Severability. The provisions of this Pledge Agreement
are severable, and if any clause or provision shall be held invalid, illegal or
unenforceable in whole or in part in any jurisdiction, then such invalidity or
unenforceability shall affect in that jurisdiction only such clause or
provision, or part thereof, and shall not in any manner affect such clause or
provision in any other jurisdiction or any other clause or provision of this
Pledge Agreement in any jurisdiction.

                  17.4     Headings. The headings in this Pledge Agreement have
been inserted for convenience of reference only, are not to be considered a part

                                                                            20


                  17.5     Counterpart Originals. This Pledge Agreement may be
signed in two or more counterparts, each of which shall be deemed an original,
but all of which shall together constitute one and the same agreement.

                  17.6     Benefits of Pledge Agreement. Nothing in this Pledge
Agreement, express or implied, shall give to any person, other than the parties
hereto and their successors hereunder, and the Holders of the Notes, any benefit
or any legal or equitable right, remedy or claim under this Pledge Agreement.

                  17.7     Amendments, Waivers and Consents. Any amendment or
waiver of any provision of this Pledge Agreement and any consent to any
departure by the Pledgor from any provision of this Pledge Agreement shall be
effective only if made or duly given in compliance with all of the terms and
provisions of the Indenture, and neither the Trustee nor any Holder of Notes
shall be deemed, by any act, delay, indulgence, omission or otherwise, to have
waived any right or remedy hereunder or to have acquiesced in any Default or
Event of Default or in any breach of any of the terms and conditions hereof.
Failure of the Trustee or any Holder of Notes to exercise, or delay in
exercising, any right, power or privilege hereunder shall not preclude any other
or further exercise thereof or the exercise of any other right, power or
privilege. A waiver by the Trustee or any Holder of Notes of any right or remedy
hereunder on any one occasion shall not be construed as a bar to any right or
remedy that the Trustee or such Holder of Notes would otherwise have on any
future occasion. The rights and remedies herein provided are cumulative, may be
exercised singly or concurrently and are not exclusive of any rights or remedies
provided by law.

                  17.8     Interpretation of Agreement. All terms not defined
herein or in the Indenture shall have the meaning set forth in the UCC, except
where the context otherwise requires. To the extent a term or provision of this
Pledge Agreement conflicts with the Indenture, the Indenture shall control with
respect to the subject matter of such term or provision. Acceptance of or
acquiescence in a course of performance rendered under this Pledge Agreement
shall not be relevant to determine the meaning of this Pledge Agreement even
though the accepting or acquiescing party had knowledge of the nature of the
performance and opportunity for objection.

                  17.9     Continuing Security Interest; Termination. (a) This
Pledge Agreement shall create a continuing security interest in and to the
Collateral and shall, unless otherwise provided in the Indenture or in this
Pledge Agreement, remain in full force and effect until the payment in full in
cash of the Obligations. This Pledge Agreement shall be binding upon the
Pledgor, its transferees, successors and assigns, and shall inure, together with
the rights and remedies of the

   25
                                                                              21


Trustee hereunder, to the benefit of the Trustee, the Holders of the Notes and
their respective successors, transferees and assigns.

                  (b)      In addition to the provisions of Section 6(e) hereof
and subject to the provisions of Section 17.10 hereof, this Pledge Agreement
shall terminate upon the payment in full in cash of the Obligations. At such
time, and subject to Section 12, the Trustee shall, pursuant to an Issuer Order,
reassign and redeliver to the Pledgor all of the Collateral hereunder that has
not been sold, disposed of, retained or applied by the Trustee in accordance
with the terms of this Pledge Agreement and the Indenture. Such reassignment and
redelivery shall be without warranty by or recourse to the Trustee in its
capacity as such, except as to the absence of any Liens on the Collateral
created by or arising through the Trustee, and shall be at the reasonable
expense of the Pledgor.

                  17.10    Survival Provisions. All representations, warranties
and covenants of the Pledgor contained herein shall survive the execution and
delivery of this Pledge Agreement, and shall terminate only upon the termination
of this Pledge Agreement. The obligations of the Pledgor under Sections 12 and
14 hereof shall survive the termination of this Pledge Agreement.

                  17.11    Waivers. The Pledgor waives presentment and demand
for payment of any of the Obligations, protest and notice of dishonor or default
with respect to any of the Obligations, and all other notices to which the
Pledgor might otherwise be entitled, except as otherwise expressly provided
herein or in the Indenture.

                  17.12    Authority of the Trustee. (a) The Trustee shall have
and be entitled to exercise all powers hereunder that are specifically granted
to the Trustee by the term hereof, together with such powers as are reasonably
incident thereto. The Trustee may perform any of its duties hereunder or in
connection with the Collateral by or through agents or employees and shall be
entitled to retain counsel and to act in reliance upon the advice of counsel
concerning all such matters. Except as otherwise expressly provided in this
Pledge Agreement or the Indenture, neither the Trustee nor any director,
officer, employee, attorney or agent of the Trustee shall be liable to the
Pledgor for any action taken or omitted to be taken by the Trustee, in its
capacity as Trustee, hereunder, except for its own bad faith, gross negligence
or willful misconduct, and the Trustee shall not be responsible for the
validity, effectiveness or sufficiency hereof or of any document or security
furnished pursuant hereto. The Trustee and its directors, officers, employees,
attorneys and agents shall be entitled to rely on any communication, instrument
or document believed by it or them to be genuine and correct and to have been
signed or sent by the proper person or persons. The Trustee shall have no duty
to cause any financing statement or continuation statement to be filed in
respect of the Collateral.

                                                                              22

                  (b)      The Pledgor acknowledges that the rights and
responsibilities of the Trustee under this Pledge Agreement with respect to any
action taken by the Trustee or the exercise or non-exercise by the Trustee of
any option, right, request, judgment or other right or remedy provided for
herein or resulting or arising out of this Pledge Agreement shall, as between
the Trustee and the Holders of the Notes, be governed by the Indenture and by
such other agreements with respect thereto as may exist from time to time among
them, but, as between the Trustee and the Pledgor, the Trustee shall be
conclusively presumed to be acting as agent for the Holders of the Notes with
full and valid authority so to act or refrain from acting, and the Pledgor shall
not be obligated or entitled to make any inquiry respecting such authority.

                  17.13    Final Expression. This Pledge Agreement, together
with the Indenture and any other agreement executed in connection herewith, is
intended by the parties as a final expression of this Pledge Agreement and is
intended as a complete and exclusive statement of the terms and conditions
thereof.

                  17.14    Rights of Holders of the Notes. No Holder of Notes
shall have any independent rights hereunder other than those rights granted to
individual Holders of the Notes pursuant to Section 607 of the Indenture;
provided that nothing in this subsection shall limit any rights granted to the
Trustee under the Notes or the Indenture.

C.F.R. ss.ss. 357.0 AND 357.11 (AS IN EFFECT ON THE DATE OF THIS PLEDGE
AGREEMENT) SHALL BE GOVERNED SOLELY BY THE LAWS SPECIFIED THEREIN.

                  (b)      THE PLEDGOR HEREBY APPOINTS CORPORATION SERVICE
COMPANY AS ITS AGENT FOR SERVICE OF PROCESS IN ANY SUIT, ACTION OR PROCEEDING

AS DEFENDANT IN ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF, CONNECTED WITH,

THE RIGHT, TO THE EXTENT PERMITTED BY APPLICABLE LAW, TO PROCEED AGAINST THE
PLEDGOR OR THE COLLATERAL IN A COURT IN ANY LOCATION REASONABLY SELECTED IN GOOD

COLLATERAL, AS THE CASE MAY BE) TO ENABLE THE TRUSTEE TO REALIZE ON SUCH
COLLATERAL, OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER ENTERED IN FAVOR OF

SETOFFS OR CROSSCLAIMS IN ANY PROCEEDING BROUGHT BY THE TRUSTEE TO REALIZE ON
SUCH PROPERTY OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER IN FAVOR OF THE
TRUSTEE, EXCEPT FOR SUCH COUNTERCLAIMS, SETOFFS OR CROSSCLAIMS WHICH, IF NOT
ASSERTED IN ANY SUCH PROCEEDING, COULD NOT OTHERWISE BE BROUGHT OR ASSERTED.

                  (d)      THE PLEDGOR AGREES THAT NEITHER ANY HOLDER OF NOTES
NOR (EXCEPT AS OTHERWISE PROVIDED IN THIS PLEDGE AGREEMENT OR THE INDENTURE) THE
TRUSTEE IN ITS CAPACITY AS TRUSTEE SHALL HAVE ANY LIABILITY TO THE PLEDGOR

TRANSACTIONS CONTEMPLATED AND THE RELATIONSHIP ESTABLISHED BY THIS PLEDGE
AGREEMENT, OR ANY ACT, OMISSION OR EVENT OCCURRING IN CONNECTION THEREWITH,
UNLESS IT IS DETERMINED BY A FINAL AND NONAPPEALABLE, JUDGMENT OF A COURT THAT
