following form (with appropriate conforming modifications in the case of the
legend appearing on any certificate representing Warrant Shares):

         "THIS WARRANT AND THE WARRANT SHARES ISSUABLE UPON THE EXERCISE HEREOF
         HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.
         THIS WARRANT AND SUCH SHARES, MAY NOT BE SOLD OR TRANSFERRED IN THE
         ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER SUCH ACT.

                                       5
<PAGE>

         THIS WARRANT IS ALSO SUBJECT TO TRANSFER RESTRICTIONS SET FORTH IN A
         WARRANT AGREEMENT, DATED AS OF MARCH 22, 2002, AMONG THE COMPANY AND
         THE OTHER PARTIES REFERRED TO THEREIN (THE "WARRANT AGREEMENT"). THIS
         WARRANT MAY BE TRANSFERRED ONLY IN COMPLIANCE WITH THE CONDITIONS
         SPECIFIED IN THE WARRANT AGREEMENT."

         (b) Prior to any transfer or attempted transfer of any Warrants, the
Holder of such Warrants shall give fifteen (15) calendar days' prior written
notice (a "TRANSFER NOTICE") to the Company of such Holder's intention to effect
such transfer, describing the manner and circumstances of the proposed transfer,
and, if reasonably requested by the Company, obtain from counsel to such Holder
who shall be reasonably satisfactory to the Company, an opinion that the
proposed transfer of such Warrants may be effected without registration under
the Securities Act. After receipt of the Transfer Notice and, if so requested,
the opinion, the Company shall, within ten (10) calendar days thereof, notify
the Holder of such Warrants that it may effect such transfer and such Holder
shall thereupon be entitled to transfer such Warrants, in accordance with the
terms of the Transfer Notice. Each Warrant issued upon such transfer shall bear
the restrictive legends set forth above, unless, with respect to the first
legend above, in the opinion of such counsel such legend is not required in
order to ensure compliance with the Securities Act. The Holder of the Warrants
giving the Transfer Notice shall not be entitled to transfer such Warrants until
receipt of notice from the Company under this Section 4 that such transfer is
permissible.

         Section 5. REGISTRATION OF TRANSFERS AND EXCHANGES. The Company shall
from time to time register any transfer permitted in accordance with Section 4
of any outstanding Warrant Certificates upon the records to be maintained by it
for that purpose, upon surrender thereof accompanied (if so required by it) by a
written instrument or instruments of transfer in a form reasonably satisfactory
to the Company, duly executed by the Holder or Holders thereof or by the duly
appointed legal representative thereof or by a duly authorized attorney. Upon
any such registration of transfer, a new Warrant Certificate shall be issued to
the transferee(s) and the surrendered Warrant Certificate shall be canceled by
the Company. Canceled Warrant Certificates shall thereafter be disposed of in a
manner satisfactory to the Company.

         Warrant Certificates may be exchanged at the option of the Holder(s)
thereof, when surrendered to the Company at its office for another Warrant
Certificate or other Warrant Certificates of like tenor and representing in the
aggregate a like number of Warrants. Warrant Certificates surrendered for
exchange shall be canceled by the Company.

         Section 6. TERMS OF WARRANTS; EXERCISE OF WARRANTS.

         (a) TERMS OF WARRANTS. Subject to the terms of this Agreement, each
Holder shall have the right to receive from the Company the number of fully-paid
and nonassessable Warrant Shares which the Holder may at the time be entitled to
receive on exercise of such Warrants and payment of the Warrant Exercise Price
then in effect for such Warrant Shares. Each Warrant not exercised prior to 5:00
p.m., New York City time, October 1, 2008, or such earlier date as the Warrants
may expire pursuant to this Agreement (the "EXPIRATION DATE") shall become void
and all rights thereunder and all rights in respect thereof under this Agreement
shall cease as of such time.

         (b) EXERCISE OF WARRANTS. At any time prior to the Expiration Date,
Warrants may be exercised upon surrender to the Company at its office of the
certificate or certificates evidencing the Warrants to be exercised with a duly
executed exercise notice in the form attached as Annex A to the Warrant
Certificate and payment to the Company for the account of the Company of the
Warrant Exercise Price, for the number of Warrant Shares in respect of which
such Warrants are then being exercised.

         Upon surrender of a Warrant Certificate in conformity with the
foregoing provisions, the Company shall transfer (or shall cause its transfer
agent to effect such transfer, in accordance with such transfer agent's
applicable procedures) to the Holder of such Warrant Certificate certificates or
other appropriate evidence of ownership of any Warrant Shares or other
securities or property and any money to which the Holder is entitled, registered
or otherwise placed in, or payable to the order of, such name or names as may be
directed in writing by the Holder, provided that if the Holder directs that all
or any part of the Warrant Shares be registered, placed in, or payable to the
order of a Person other than the Holder, the provisions of Section 4(b) shall be
complied with prior to such registration, placement, or payment, and the Company
shall deliver such certificates or other evidence of ownership and any money to
the Person or Persons entitled to receive the same. If more than one Warrant
Certificate shall be surrendered for exercise or sale of the Warrants
represented thereby at one time by the same Holder, the total number of full
Warrant Shares or other securities or property (including any money) to which
the Holder is entitled which shall be deliverable upon tender thereof shall be
computed on the basis of the aggregate number of Warrants tendered.

         A Warrant shall be deemed to have been exercised or sold immediately
prior to the close of business on the date of the surrender for such exercise or
sale of the Warrant Certificate representing such Warrant and satisfaction of
the other requirements set forth in this Section 6(b) and, for all purposes of
this Agreement, the Person entitled to receive any Warrant Shares or other
securities or property (including any money) deliverable upon such exercise or
sale shall, as between such Person and the Company, be deemed to be the Holder

                                       7
<PAGE>

of such Warrant Shares or other securities or property of record as of the close
of business on such date and shall be entitled to receive any money, Warrant
Shares or other securities or property to which such Holder would have been
entitled had such Holder been the record Holder on such date.

         Without limiting the foregoing, if, at the date referred to above, the
transfer books for the Warrant Shares or other securities to be received upon
the exercise of the Warrants shall be closed, the certificates for the Warrant
Shares or other securities in respect of which such Warrants are then exercised
shall be transferred when such transfer books shall next be opened and until
such date the Company shall be under no duty to deliver any certificates for
such Warrant Shares or other securities; provided, however, that the transfer
books of record, unless required by law, shall not be closed at any time for a
period longer than twenty (20) calendar days.

         The Warrants shall be exercisable, subject to the terms of this
Agreement, at the election of the Holders thereof, either in full or from time
to time in part and, in the event that a certificate evidencing Warrants is
exercised in respect of fewer than all of the Warrant Shares issuable on such
exercise at any time prior to the date of expiration of the Warrants, the
Company will issue and deliver a new certificate (or certificates) evidencing
the remaining Warrant or Warrants pursuant to the provisions of this Section 6.

         The Company shall keep copies of this Agreement and any notices given
or received hereunder and thereunder available for inspection by the Holders
during normal business hours at its office.

         Section 7. RIGHTS AS A STOCKHOLDER. Nothing contained in this Warrant
Agreement shall be construed as conferring upon the Holder any rights as a
stockholder of the Company with respect to any shares covered by the Warrants
until the date of issuance of such shares, including, but not limited to, any
right to vote or to consent or to receive notice as a stockholder in respect of
the meetings of stockholders or the election of directors of the Company or any
other matter.

         Section 8. ANTIDILUTION. The following provisions shall govern dilution
of the Warrant Shares issuable upon the exercise of each Warrant.

         (a) COMMON STOCK SPLITS. Upon any subdivision by the Company on or
after the date hereof of all of its outstanding shares of Common Stock into a
greater number of shares or upon any issuance by the Company on or after such
date of a greater number of shares of Common Stock in a pro rata exchange for
all of its outstanding shares of Common Stock, then in each case from and after
the record date for such subdivision or exchange the number of Warrant Shares
purchasable upon the exercise of the Warrants shall be increased in proportion
to such increase in the number of outstanding shares of Common Stock, and the
Warrant Exercise Price then in effect shall be correspondingly decreased, but
not below the applicable par value of the Shares. Upon any pro rata reduction by

                                       8
<PAGE>

the Company on or after the date hereof of its outstanding shares of Common
Stock as a whole or upon any issuance by the Company after such date of a lesser
number of shares of Common Stock in a pro rata exchange for all of its
outstanding shares of Common Stock, then in each case from and after the record
date for such reduction or exchange the number of Warrant Shares purchasable
upon the exercise of the Warrants shall be decreased in proportion to such
reduction in the number of outstanding shares of Common Stock, and the Warrant
Exercise Price shall be correspondingly increased.

         (b) COMMON STOCK DIVIDENDS. Upon any declaration and payment by the
Company on or after the date hereof of a dividend upon Common Stock payable in
Common Stock, then from and after the record date for the payment of such stock
dividend, the number of Warrant Shares purchasable upon the exercise of the
Warrants shall be increased in proportion to the increase in the number of
outstanding shares of Common Stock through such stock dividend, and the Warrant
Exercise Price shall be correspondingly decreased, but not below the applicable
par value of the Shares.

         (c) EFFECT OF REORGANIZATION AND ASSET SALES. If any capital
reorganization of the Company, reclassification of the capital stock of the
Company, statutory exchange, consolidation, or merger of the Company with
another Person, or sale of all or substantially all of the Company's assets to
another Person shall be effected in such a way that holders of Common Stock
shall be entitled to receive stock, securities, or assets (including cash) of
the Company or another Person with respect to or in exchange for Common Stock
(each such transaction being hereinafter referred to as a "TRANSACTION"), then,
as a condition of the consummation of each Transaction, lawful and adequate
provisions shall then be made so that each holder of Warrants, upon the exercise
of any Warrant at any time after the consummation of such Transaction, shall be
entitled to receive, and such Warrants shall thereafter represent the right to
receive, in lieu of the Shares issuable upon exercise of such Warrant but
otherwise upon and subject to all terms and conditions hereof, the cash,
securities, or other property to which such holder would have been entitled upon
the consummation of such Transaction if such holder had exercised such Warrants
immediately prior thereto (subject to adjustments from and after the
consummation date of such Transaction as nearly equivalent as possible to the
adjustments provided for in this Section 8). The Company shall not effect any
Transaction unless prior to the consummation thereof each Person (other than the
Company) who may be required to deliver any securities or other property upon
the exercise of the Warrants as provided herein shall assume, by written
instrument delivered to each holder of the Warrants in form and substance
reasonably satisfactory to such holder, the obligation to continue to honor this
Warrant Agreement and to deliver to such holder such securities or other
property to which, in accordance with the foregoing provisions, such holder may
be entitled.

                                       9
<PAGE>

         Section 9. NO IMPAIRMENT. The Company (A) will not permit the par or
nominal value of any Warrant Shares issuable upon the exercise of Warrants to
exceed the amount payable therefor upon such exercise, (B) will take all such
action as may be necessary or appropriate in order that the Company may validly
and legally issue fully paid and nonassessable Warrant Shares on the exercise of
the Warrants from time to time outstanding and (C) will not take any action
which results in any adjustment of the number of Warrant Shares issuable upon
exercise of each Warrant if the total number of shares of Common Stock (or other
securities) issuable after the action upon the exercise of all of the Warrants
would exceed the total number of shares of Common Stock (or other securities)
then authorized by the Company's Certificate of Incorporation and available for
the issuance of shares of Common Stock (or other securities) upon such exercise.

         Section 10. REGISTRATION RIGHTS.

         (a) SECURITIES SUBJECT TO THIS AGREEMENT. The securities entitled to
the benefits of this Section are the Registrable Securities. For the purposes of
this Agreement, any particular Registrable Securities will cease to be
Registrable Securities when and to the extent that (I) a Registration Statement
covering such Registrable Securities has been declared effective under the
Securities Act and such Registrable Securities have been disposed of pursuant to
such effective Registration Statement, (II) such Registrable Securities are
distributed to the public pursuant to Rule 144 (or any similar provision then in
force) under the Securities Act, (III) such Registrable Securities shall have
been otherwise transferred or disposed of, new certificates therefore not
bearing a legend restricting further transfer shall have been delivered by the
Company and, at such time, subsequent transfer or disposition of such securities
shall not require registration or qualification of such securities under the
Securities Act or any similar state law then in force or (IV) such Registrable
Securities have ceased to be outstanding.

         (b) PIGGY-BACK REGISTRATION RIGHTS.

                  (i) Whenever during the Effective Period the Company shall
         propose to file a registration statement under the Securities Act
         relating to public offering of Common Stock for the Company's own
         account (other than pursuant to a registration statement on Form S-4 or
         Form S-8 or any successor forms, or filed in connection with an
         exchange offer or an offering of securities solely to existing
         stockholders or employees of the Company) or for the account of any
         holder of Common Stock (the "INITIATING HOLDER") and on a form and in a
         manner that would permit registration of Registrable Securities for
         sale to the public under the Securities Act the Company shall (I) give
         written notice at least 20 Business Days prior to the filing thereof to
         each Holder of Registrable Securities then outstanding, specifying the
         approximate date on which the Company proposes to file such

                                       10
<PAGE>

         registration statement and advising such Holder of its right to have
         any or all of the Registrable Securities then held by such Holder
         included among the securities to be covered thereby and (II) at the
         written request of any Holder given to the Company within 15 days after
         such Holder's receipt of written notice from the Company, include among
         the securities covered by such registration statement the number of
         Registrable Securities which such Holder (the "REQUESTING HOLDER")
         shall have requested be so included (subject, however, to reduction in
         accordance with clause (ii) of this subsection (b)).

                  (ii) Each Holder desiring to participate in an offering
         pursuant to clause (I) of this subsection may include shares of Common
         Stock in any Registration Statement relating to such offering to the
         extent that the inclusion of such shares of Common Stock shall not
         reduce the number of shares of Common Stock to be offered and sold by
         the Company or any Initiating Holder pursuant thereto. If the lead
         managing underwriter selected by the Company for an underwritten
         offering pursuant to clause (I) of this subsection determines
         reasonably and in good faith that marketing factors require a
         limitation on the number of shares of Common Stock to be offered and
         sold by Requesting Holders in such offering, there shall be included in
         the offering only that number of shares of Common Stock, if any, that
         such lead managing underwriter reasonably and in good faith believes
         will not jeopardize the success of the offering of all the shares of
         Common Stock that the Company desires to sell for its own account or
         that the Initiating Holder desires to sell for its own account, as the
         case may be. In such event and provided the lead managing underwriter
         has so notified the Company in writing, the shares of Common Stock to
         be included in such offering shall consist of (I) first, any securities
         the Company or the Initiating Holder, as the case may be, proposes to
         sell, and (II) second, the number, if any, of Registrable Securities
         the Requesting Holders requested to be included in such registration
         that, in the opinion of such lead managing underwriter can be sold
         without jeopardizing the success of the offering of all the securities
         that the Company or the Initiating Holder, as the case may be, desires
         to sell for its own account, such amount to be allocated on a pro rata
         basis among the Holders of Registrable Securities who have requested
         their securities be so included based on the number of Registrable
         Securities that each Holder thereof has requested to be so included;
         provided that, in the event another Person has duly requested pursuant
         to an agreement with the Company that the Company register other
         securities of the Company and such request has not been withdrawn, the
         Requesting Holders and such other Person shall be included in such
         registration pro rata based on the number of securities the Requesting
         Holders and such other Person have requested to be so included.

                  (iii) Nothing in this subsection (b) shall create any
         liability on the part of the Company to the Holders of Registrable
         Securities if the Company for any reason should decide not to file a
         registration statement proposed to be filed under subsection (a) or to

                                       11
<PAGE>

         withdraw such registration statement subsequent to its filing,
         regardless of any action whatsoever that a Holder may have taken,
         whether as a result of the issuance by the Company of any notice
         hereunder or otherwise.

                  (iv) A request by Holders to include Registrable Securities in
         a proposed underwritten offering pursuant to this subsection (b) shall
         not be deemed to be a request for a demand registration pursuant to
         subsection (c).

         (c) DEMAND REGISTRATION RIGHTS.

                  (i) Upon the written request during the Effective Period of
         Holders holding at least a majority in number of the Registrable
         Securities held by the Holders that the Company effect the registration
         with the SEC under and in accordance with the provisions of the
         Securities Act of all or part of such Holders' Registrable Securities

         Registrable Securities requested to be registered and the means of
         distribution), the Company shall file a Registration Statement covering
         such Holders' Registrable Securities requested to be registered within
         30 Business Days after receipt of such request provided, however, that
         the Company shall not be required to take any action pursuant to this
         subsection (c):

                  (A)      if within 12 months prior to the date of such request
                           the Company shall have effected a registration
                           pursuant to this subsection (c);

                  (B)      if the Company has effected a registration within the
                           180-day period preceding such request which permitted
                           Holders holding Registrable Securities to register
                           Registrable Securities and has agreed with the
                           underwriters in connection with such prior
                           registration not to offer its securities publicly for
                           such 180-day period;

                  (C)      if the Company shall at the time have effective a
                           Shelf Registration pursuant to which the Holders
                           entitled to request registration under this
                           subsection (c) could effect the disposition of such
                           Holders' Registrable Securities in the manner
                           requested;

                  (D)      if the Registrable Securities which the Company shall
                           have been requested to register shall have a then
                           current market value of less than $20,000, unless
                           such registration request is for all remaining
                           Registrable Securities held by the Holders; or

                  (E)      during the pendency of any Blackout Period;

provided, however, that the Company shall be permitted to satisfy its
obligations under this subsection (c) by amending (to the extent permitted by

                                       12
<PAGE>

applicable law) within 15 Business Days after a written request for
registration, any Registration Statement previously filed by the Company under
the Securities Act so that such Registration Statement (as amended) shall permit
the disposition (in accordance with the intended methods of disposition
specified as aforesaid) of all of the Registrable Securities for which a demand
for registration has been made under this subsection (c). If the Company shall
so amend a previously filed Registration Statement, it shall be deemed to have
effected a registration for purposes of this subsection (c).

                  (ii) The Holders delivering such request may distribute the
         Registrable Securities covered by such request by means of an
         underwritten offering or any other means, as determined by the Holders
         holding a majority of Registrable Securities so requested to be
         registered.

                  (iii) Subject to clause (iv) of this subsection (c), a
         registration requested pursuant to this subsection (c) shall not be
         deemed to be effected for purposes of this subsection (c) if it has not
         been declared effective by the SEC or become effective in accordance
         with the Securities Act and the rules and regulations thereunder.

                  (iv) Holders holding a majority in number of the Registrable
         Securities held by Holders to be included in a Registration Statement
         pursuant to this subsection (c) may, at any time prior to the effective
         date of the Registration Statement relating to such registration,
         revoke such request by providing a written notice to the Company
         revoking such request. If a Registration Statement is so revoked, the
         Holders holding Registrable Securities requesting the filing of such
         Registration Statement shall reimburse the Company for all its
         out-of-pocket expenses incurred in the preparation, filing and
         processing of the Registration Statement. In the case of any such
         revocation, the Company shall be deemed to have effected a registration
         pursuant to this subsection (c).

                  (v) In the event the Company wishes, or any holder of Common
         Stock has the right, to include shares of Common Stock in a
         Registration Statement pursuant to this subsection (c), there shall be
         included in, such Registration Statement only that number of such
         shares of Common Stock, if any, that the lead managing underwriter (if
         the offering covered by such Registration Statement is an underwritten
         offering) reasonably and in good faith believes will not jeopardize the
         success of the offering of all the shares of Common Stock that the
         Holders desire to sell for their own account. In such event and
         provided the lead managing underwriter has so notified the Company in

                                       13
<PAGE>

         writing, the shares of Common Stock to be included in such offering,
         shall consist of (I) first, the securities the Holders propose to -
         sell, (II) second, the securities the Company proposes to sell for its
         own account and (III) third, the -- --- number, if any, of securities
         requested to be included in such registration that, in the reasonable
         and good faith opinion of such lead managing underwriter can be sold
         without jeopardizing the success of the offering of all the, securities
         that any other Persons holding securities of the Company and entitled
         to piggy-back rights or the Company, as the case may be, desires to
         sell for its own account, such amount to be allocated on a pro rata
         basis among such Persons and the Company who have requested their
         securities be so included based on the number of securities that each
         holder thereof has requested to be so included. If the offering covered
         by such Registration Statement is not an underwritten offering, the
         Company shall not include any securities which are not Registrable
         Securities in such Registration Statement without the prior written
         consent of the Holders holding a majority in number of the Registrable
         Securities, held by Holders and covered by such Registration Statement.

         (d) SELECTION OF UNDERWRITERS. In connection with any underwritten
offering pursuant to a Registration Statement filed pursuant to a demand made
pursuant to subsection (c) of this Section, the Company shall have the right to
select a lead managing underwriter or underwriters to administer the offering,
which lead managing underwriter or underwriters shall be reasonably satisfactory
to the Holders holding a majority in number of the Registrable Securities to be
included in the Registration Statement; provided, however, that the Holders
holding a majority in number of the Registrable Securities to be included in the
Registration Statement shall have the right to select a co-lead managing or
co-managing underwriter or underwriters for the offering, which co-lead managing
or co-managing underwriter or underwriters shall be reasonably satisfactory to
the Company.

         (e) BLACKOUT PERIOD; HOLDBACK.

                  (i) If the Company determines in good faith that the
         registration and distribution of Registrable Securities (I) would
         materially impede, delay, interfere with or otherwise adversely affect
         any pending financing, registration of securities, acquisition,
         corporate reorganization or other significant transaction involving the
         Company or (II) would require disclosure of non-public material
         information that the Company has a bona fide business purpose for
         preserving as confidential, as determined by the Board of Directors of
         the Company in good faith, the Company shall promptly give the Holders
         notice of such determination and shall be entitled to postpone the
         filing or effectiveness of a Registration Statement for the shortest
         period of time reasonably required, but in any event up not to exceed
         120 days with respect to matters covered by clause (I) above, and not

                                       14
<PAGE>

         to exceed 90 days with respect to matters covered by clause (II) above
         (a "BLACKOUT PERIOD"); provided, that a Blackout Period with respect to
         a registration of securities proposed by the Company may, at the
         election of the Company, commence on the date that is 30 days prior to
         the date the Company in good faith estimates will be the date of filing
         of, and end no later than the date, following the effective date of
         such registration, specified in the form of underwriting agreement
         relating to such registration during which the Company shall be
         prohibited from selling, offering, or otherwise disposing of Common
         Stock, but in no event to exceed 90 days, and provided further, that
         the Company shall not obtain any deferrals under this subsection (e)
         aggregating in excess of 180 days in any twelve-month period. The
         Company shall promptly notify each Holder of the expiration or earlier
         termination of a Blackout Period.

                  (ii) Each Holder agrees by acquisition of the Registrable
         Securities, if so requested in writing by any managing underwriter, not
         to effect any public sale or distribution of such securities or Related
         Securities during the seven days prior to and the 180 days after the
         effective time of any underwritten registration by the Company (either
         for its own account, or for the benefit of the Holders of any
         securities of the Company, including Registrable Securities, in each
         case as to which the Holders are entitled to request to be included
         pursuant to subsection (b) has become effective or such period of time
         shorter than 180 days that is sufficient and appropriate, in the
         reasonable and good faith opinion of the managing underwriter, in order
         to complete the sale and distribution of securities included in such
         registration.

         (f) REGISTRATION PROCEDURES. If and whenever the Company is required to
use reasonable best efforts to effect or cause the registration of any
Registrable Securities under the Securities Act as provided in this Agreement,

         Registrable Securities in accordance with the intended methods of
         distribution thereof (including, if so requested by the Holders,

         therewith as may be necessary to maintain the effectiveness of such

         covered by such Registration Statement until the earlier of (X) such
         90thday (or longer period) and (Y) such time as all Registrable

         things which may be reasonably necessary to enable such Holder to
         consummate the disposition in such jurisdictions of the Registrable
         Securities owned by such Holder, except that the Company shall not be
         required for any such purpose to qualify generally to do business as a
         foreign corporation in any jurisdiction where, but for the requirements
         of this clause (iv) it would not be obligated to be so qualified, to

                           notification of the suspension of the qualification
                           of any of the Registrable Securities for sale in any
                           jurisdiction or the initiation of any threats of any

                           certificates as may be reasonably requested by the

                           paragraph (v) above and with any customary conditions

         its subsidiaries and Affiliates (collectively, the "RECORDS") as shall
         be reasonably necessary to enable them to exercise their due diligence
         responsibility; provided, however, that the Records that the Company
         determines, in good faith, to be confidential shall not be disclosed to
         any Inspector unless such Inspector signs or is otherwise bound by a
         confidentiality agreement reasonably satisfactory to the Company; and

                  (xiii) in the event of the issuance of any stop order of which
         the Company or its counsel is aware suspending ` the effectiveness of
         the Registration Statement, or of any order suspending or preventing
         the use of any related Prospectus or suspending the Prospectus or
         suspending the qualification of any Registrable Securities included in
         the Registration Statement for sale in any jurisdiction, the Company
         shall use its reasonable best efforts promptly to obtain its

relating to the registration and the distribution of such securities as the
Company may from time to time reasonably request.

covering such Registrable Securities until such Holder's receipt of the copies
of the supplemented or amended Prospectus contemplated by clause (f)(v) or the
withdrawal of any stop order contemplated by clause (f)(xii), and, if so
directed by the Company, such Holder shall deliver to the Company all copies,
other than permanent files copies then in such Holder's possession, of the
Prospectus covering such Registrable Securities at the time of receipt of such
notice.

         (i) INDEMNIFICATION: CONTRIBUTION.

                  (i) The Company agrees to indemnify and hold harmless each
         Holder of Registrable Securities, its officers, directors, agents,
         trustees, stockholders and each Person who controls such Holder (within
         the meaning of Section 15 of the Securities Act or Section 20 of the
         Exchange Act), against all losses, claims, damages, liabilities and
         expenses (including reasonable attorneys fees, disbursements and
         expenses, as incurred) incurred by such party pursuant to any actual or
         threatened action, suit, proceeding or investigation arising out of or
         based upon any untrue or alleged untrue statement of a material fact
         contained in the Registration Statement, any Prospectus or preliminary
         Prospectus, or any amendment or supplement to any of the foregoing, or
         any omission or alleged omission to state therein a material fact
         required to be stated therein or necessary to make the statements
         therein (in the case of a Prospectus or a preliminary Prospectus, in
         the light of the circumstances then existing) not misleading, except in
         each case insofar as the same arise out of or are based upon (I) any
         such untrue statement or omission made in reliance on and in conformity
         with information with respect to such indemnified party furnished in
         writing to the Company by such indemnified party or its counsel
         expressly for use therein, (II) the use of any Prospectus after such
         time as the obligation of the Company to keep such Prospectus effective
         has expired or (III) the use of any Prospectus after such time as the

                                       20
<PAGE>

         Company has advised the Holders that the filing of a post-effective
         amendment or supplement thereto is required, except such Prospectus as
         so amended or supplemented. In connection with an underwritten
         offering, the Company shall indemnify the underwriters thereof their
         officers, directors, agents, trustees, stockholders and each Person who
         controls such underwriters (within the meaning of Section 14 of the
         Securities Act or Section 20 of the Exchange Act) to the same extent as
         provided above with respect to the indemnification of the Holders of
         Registrable Securities. Notwithstanding the foregoing provisions of
         this clause (i) of subsection (i), the Company shall not be liable to
         any Person who participates as an underwriter in the offering or sale
         of Registrable Securities or any other Person, if any, who controls
         such underwriter (within the meaning of Section 15 of the Securities
         Act or Section 20 of the Exchange Act), under the indemnity agreement
         in this clause (i) of subsection (i) for any such loss, claim, damage,
         liability (or action or proceeding in respect thereof) or expense that
         arises out, of any of the matters specified in clause (II) or (III)
         above or such Person's failure to send or deliver a copy of the final
         Prospectus to the Person asserting an untrue statement or alleged
         untrue statement or omission or alleged omission at or prior to the
         written confirmation of the sale of Registrable Securities to such
         Person if such statement or omission was corrected in such final
         Prospectus and the Company has previously furnished copies thereof to
         such Holder or other Person in accordance with this Agreement.

                  (ii) In connection with any Registration Statement filed
         pursuant hereto, each Holder of Registrable Securities to be covered
         thereby shall furnish to the Company in writing such information with
         respect to such Holder, including the Holder's name and address and the
         amount of Registrable Securities held by such Holder, as the Company
         reasonably requests for use in such Registration Statement or the
         related Prospectus and agrees, jointly and severally with all other
         Holders that are Affiliates of such Holder (and, otherwise, severally
         and not jointly with all other Holders), to indemnify and hold harmless
         the Company, all other Holders or any underwriter, as the case may be,
         and their respective directors, officers, agents, trustees,
         stockholders and controlling Persons (within the meaning of Section 15
         of the Securities Act, or Section 20 of the Exchange Act), against any
         losses, claims, damages, liabilities and expenses (including reasonable
         attorney's fees, disbursements and expenses, as incurred), incurred by
         such party pursuant to any actual or threatened action, suit,
         proceeding or investigation arising out of or based upon any untrue or
         alleged untrue statement of a material fact contained in, or any
         omission or alleged omission of a material fact required to be stated
         in, such Registration Statement, Prospectus or preliminary Prospectus
         or any amendment or supplement to any of the foregoing or necessary to
         make the statements therein (in case of a Prospectus or preliminary

                                       21
<PAGE>

         Prospectus, in the light of the circumstances then existing) not
         misleading, but only to the extent that any such untrue statement or
         omission is made in reliance on and in conformity with information with
         respect to such Holder furnished in writing to the Company by such
         Holder or its counsel specifically for inclusion therein; provided,
         however, that the liability of each Holder hereunder shall be limited
         to the proportion of any such loss, claim, damage, liability or expense
         that is equal to the proportion that the net proceeds from the sale of
         shares sold by such Holder under such registration statement bears to
         the total net proceeds from the sale of all securities sold thereunder
         but not in any event to exceed the not proceeds (after deduction of
         underwriting discounts and commissions and offering expenses payable by
         such Holder) received by such Holder from the sale of Registrable
         Securities covered by such Registration Statement.

                  (iii) Any Person entitled to indemnification hereunder agrees
         to give prompt written notice to the indemnifying party after the
         receipt by such indemnified party of any written notice of the
         commencement of any action, suit, proceeding or investigation or threat
         thereof made in writing for which such indemnified party may claim
         indemnification or contribution pursuant to this Agreement, provided
         that failure to give such notification shall not affect, the
         obligations of the indemnifying party pursuant to this subsection (i)
         except to the extent the indemnifying party shall have been actually
         prejudiced as a result of such failure. In case any such action shall
         be brought against any indemnified party and it shall not notify the
         indemnifying party of the commencement thereof, the indemnifying party
         shall be entitled to participate therein and, to the extent that it
         shall wish, jointly with any other indemnifying party similarly
         notified, to assume the defense thereof, with counsel reasonably
         satisfactory to such indemnified Party, and after notice from the
         indemnifying party to such indemnified party of its election so to
         assume the defense thereof, the indemnifying party shall not be liable
         to such indemnified party under these indemnification provisions for
         any legal expenses of other counsel or any. other expenses, in each
         case subsequently incurred by such indemnified party, in connection
         with the defense thereof other than reasonable costs of investigation,
         unless in the reasonable judgment of any indemnified party a conflict
         of interest is likely to exist, based on the written opinion of
         counsel, between such indemnified party and any other of such
         indemnified parties with respect to such claim, the indemnifying party

                                       22
<PAGE>

         shall not be liable for the fees and expenses of (I) more than one
         counsel for all Holder's of Registrable Securities who are indemnified
         parties, selected by a majority of the Holders of Registrable
         Securities who are indemnified parties (which choice shall be
         reasonably satisfactory to the Company), (II) more than one counsel for
         the underwriters or (III) more than one counsel for the Company in
         connection with any one action or separate but similar or related
         actions. An indemnifying party who is not entitled to, or elects not
         to, assume the defense of a claim shall not be obligated to pay the
         fees and expenses of more than one counsel for all parties indemnified
         by such indemnifying party with respect to such claims, unless in the
         reasonable judgment of any indemnified party based on the written
         opinion of counsel a conflict of interest may exist between indemnified
         party and any other of such indemnified parties with respect to such
         claim, in which event the indemnifying party shall be obligated to pay
         the fees and expenses of such additional counsel or counsels, provided
         that the indemnifying party shall not be liable for the fees and
         expenses of (X) more than one counsel for all Holders of Registrable
         Securities who are indemnified parties (which choice shall be
         reasonably satisfactory to the Company), (Y) more than one counsel for
         the underwriters or (Z) more than one counsel for the Company in
         connection with any one action or separate but similar or related
         actions. No indemnifying party, in defense of any such action, suit,
         proceeding or investigation, shall, except with the consent of each
         indemnified party, consent to the entry of any judgment or entry into
         any settlement which does not include as an unconditional term thereof
         the giving by the claimant or plaintiff to such indemnified party of a
         release from all liability in respect to such action, proceeding or
         investigation to the extent the same is covered by the indemnity
         obligations set forth in this subsection (i). No indemnified party
         shall consent to entry of any judgment or enter any settlement without
         the consent of each indemnifying party.

                  (iv) If the indemnification from the indemnifying party
         provided for in this subsection (i) is unavailable to an indemnified
         party hereunder in respect to any losses, claims, damages, liabilities
         or expenses referred to herein, then the indemnifying party, in lieu of
         indemnifying such indemnified party, shall contribute to the amount
         paid or payable by such indemnified party as a result of such losses,
         claims, damages, liabilities and expenses in such proportion as is
         appropriate to reflect the relative fault of the indemnifying party and
         indemnified party in connection with the actions which resulted in such
         losses, claims, damages, liabilities and expenses, as well as any other
         relevant equitable considerations; provided, however, that the
         liability of each Holder hereunder shall be limited to the proportion
         of any such loss, claim, damage, liability or expense that is equal to
         the proportion that the net proceeds from the sale of shares sold by
         such Holder under such Registration Statement bears to the total net
         proceeds from the sale of all securities sold thereunder, but not in
         any event to exceed the net proceeds (after deduction of underwriting
         discounts and commissions and offering expenses payable by such Holder)
         received by such Holder from the sale of Registrable Securities covered
         by such Registration Statement. The relative fault of such indemnifying
         party and indemnified party shall be determined by reference to, among
         other things, whether any action in question, including any untrue or

                                       23
<PAGE>

         alleged untrue statement of a material fact or omission or alleged
         omission to state a material fact, has been made by, or relates to
         information supplied by, such indemnifying party or indemnified party,
         and the parties' relative intent, knowledge, access to information and
         opportunity to correct or prevent such action. The amount paid or
         payable by a party as a result of the losses, claims, damages,
         liabilities and expenses referred to above shall be deemed to include,
         subject to the limitations set forth in clause (iii) of subsection (i),
         any legal or other fees and expenses reasonably incurred by such
         indemnified party in connection with any investigation or proceeding.

         No Person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any
Person who was not guilty of such fraudulent misrepresentation.

         If indemnification is available under this subsection (i) the
indemnifying parties shall indemnify each indemnified party, to the full extent
provided in clauses (i) or (ii) of subsection (i), as the case may be, without
regard to, the relative fault of such indemnifying parties or indemnified party
or any other equitable consideration provided for in this clause (iv).

                  (v) The provisions of this subsection (i) shall be in addition
         to any liability which any indemnifying Party may have to any
         indemnified party and shall survive the termination of this Agreement.

         (j) PARTICIPATION IN UNDERWRITTEN OFFERINGS. No Holder of Registered
Securities may participate in any underwritten offering pursuant to subsection
(b) unless such Holder (I) agrees to sell such Holder's securities on the basis
provided in any underwriting arrangements approved by the Company in its
reasonable discretion and (II) completes and executes all questionnaires, powers
of attorney, custody agreements, indemnities, underwriting agreements and other
documents reasonably required under the terms of such underwriting arrangements.

         (k) MERGERS, ETC. The Company agrees that, as a condition to any
merger, consolidation or the sale of all or substantially all of its assets in
exchange for securities of another company, it shall use its reasonable best
efforts in light of the circumstances then existing to require the surviving,
consolidated or purchasing corporation to enter into an agreement to register
the securities of such surviving, consolidated or purchasing corporation, to be
received by the Holders, on substantially the same terms and provisions as are
provided in this Agreement.

         (l) ASSIGNMENT OF REGISTRABLE RIGHTS. The right to cause the Company to
register Registrable Securities pursuant to this Section 10 may not be
transferred or assigned by a Holder except (I) in the case of the demand rights
specified in subsection (c), to any transferee or assignee that is an Affiliate
of AT&T Corp. (provided that such assignment shall become void automatically
from and after the first date that such transferee ceases to be an Affiliate of

                                       24
<PAGE>

AT&T Corp.), (ii) in the case of the piggy-back rights specified in subsection
(b), to any transferee or assignee which, after such assignment or transfer,
holds at least 20% of the then outstanding Registrable Securities, and (iii) in
any case, only in accordance with a valid transfer of Warrants under Section 4
and together with all related obligations in this Section 10 of such
transferring or assigning Holder.

         (m) NO INCONSISTENT AGREEMENTS. Without the prior consent of Holders
holding (or entitled to acquire, upon exercise of Warrants) a majority of the
outstanding Registrable Securities, the Company shall not hereafter, enter into
any agreement with respect to its securities which is inconsistent with or in
any way shall limit the rights granted to the Holders in this Section 10.

         Section 11. PAYMENT OF TAXES. The Company will pay all documentary
stamp taxes attributable to the initial issuance of Warrant Shares upon the
exercise of Warrants; provided that the Company shall not be required to pay any
tax or taxes which may be payable in respect of any transfer involved in the
issue of any Warrant Certificates or any certificates for Warrant Shares in a
name other than that of the registered Holder of a Warrant Certificate
surrendered upon the exercise of a Warrant, and the Company shall not be
required to issue or deliver such Warrant Certificates unless or until the
Person or Persons requesting the issuance thereof shall have paid to the Company
the amount of such tax or shall have established to the satisfaction of the
Company that such tax has been paid.

         Section 12. MUTILATED OR MISSING WARRANT CERTIFICATES. In case any of
the Warrant Certificates shall be mutilated, lost, stolen or destroyed, the
Company, in its discretion, may issue, in exchange and substitution for and upon
cancellation of the mutilated Warrant Certificate, or in lieu of and
substitution for the Warrant Certificate lost, stolen or destroyed, a new
Warrant Certificate of like tenor and representing an equivalent number of
Warrants, but only upon receipt of evidence reasonably satisfactory to the
Company of the loss, theft or destruction of such Warrant Certificate and
indemnity, if requested, also satisfactory to the Company. Applicants for such
substitute Warrant Certificates shall also comply with such other reasonable
regulations and the terms of the Securities Purchase Agreement and pay such
other reasonable charges as the Company may prescribe.

         Section 13. RESERVATION OF WARRANT SHARES. The Company will at all
times reserve and keep available, free from preemptive rights, out of the
aggregate of its authorized but unissued Common Stock or its authorized and
issued Common Stock held in its treasury, for the purpose of enabling it to
satisfy any obligation to issue Warrant Shares upon exercise of Warrants, the
maximum number of shares of Common Stock which may then be deliverable upon the
exercise of all outstanding Warrants.

         The Company represents, warrants and agrees that all Warrant Shares
which may be issued upon exercise of Warrants, upon issue, will be fully paid,
nonassessable, free of preemptive rights and free from all taxes, liens, charges

                                       25
<PAGE>

and security interests, other than those resulting from actions or agreements of
the Holders.

         Section 14. NOTICES TO HOLDERS. Not less than twenty (20) days prior to
the happening of an event requiring (i) an adjustment of the Warrant Exercise
Price, (ii) a change in the number of Warrant Shares issuable upon the exercise
of Warrants, or (iii) a change in the rights of the holder of Warrants by reason
of other events herein set forth, the Company shall give written notice to each
holder of Warrants: (A) describing the event; (B) stating the adjusted Warrant
Price, the number of Shares issuable based upon the difference between the
Warrant Price before and after such adjustment; and (C) stating how such
adjustment of the Warrant Price or number of Shares was calculated and the facts
on which the calculation is based.

         Section 15. NOTICES TO COMPANY. Any notice or demand authorized by this
Agreement to be given or made by the Holder of any Warrant Certificate to or on
the Company shall be sufficiently given or made when and if deposited in the
mail, first class or registered, postage prepaid, addressed, or sent by
telecopier as follows:

                  (e) The Borrower shall notify the Administrative Agents of any
election to terminate or reduce the Commitments of any Class under paragraph (d)

thereof. Promptly following receipt of any such notice, each Administrative
Agent shall advise the Lenders in its Lender Group of the contents thereof. Each
notice delivered by the Borrower pursuant to this Section shall be irrevocable.
Any termination or reduction of the Commitments shall be permanent. Each
reduction or termination of the Commitments pursuant to paragraph (c) of this
Section shall be applied as provided in Section 2.03(g). Each reduction or

terminate or reduce Commitments under a Participating Credit Agreement (without
terminating or ratably reducing other Commitments) if Holdings and the Borrower
certify to the Administrative Agents under the other Participating Credit

Event", the Borrower shall, substantially simultaneously with the receipt of
such Net Proceeds, prepay Borrowings and Other Senior Secured Indebtedness and
reduce Commitments in accordance with paragraphs (f) and (g) below in an
aggregate principal amount equal to such Net Proceeds; PROVIDED that the
Borrower shall not be required to make any such prepayment or reduction of
Commitments in

                                       51
<PAGE>

connection with any event described in clause (a) or (b) of the definition of
"Prepayment Event", unless the Net Proceeds from such event (or any related
series of such events) exceed $1,000,000; PROVIDED FURTHER that, in the case of
any event described in clause (a) or (b) of the definition of the term
"Prepayment Event", if Holdings shall deliver to the Administrative Agents a
certificate of a Financial Officer to the effect that Holdings elects to apply
the Net Proceeds from such event (or a portion thereof specified in such
certificate), within the Reinvestment Period in respect of such Net Proceeds, to
acquire real property, equipment or other tangible assets (in each case, that
will constitute Collateral) to be used in the Project (in the case of an event
described in clause (a) of the definition of the term "Prepayment Event") or to
repair, restore or replace the affected property or asset (in the case of an
event described in clause (b) of the definition of the term "Prepayment Event"),
and certifying that no Event of Default has occurred and is continuing, then no
prepayment or reduction of Commitments shall be required pursuant to this
paragraph in respect of the Net Proceeds in respect of such event (or the
portion of such Net Proceeds specified in such certificate, if applicable)
except to the extent of any such Net Proceeds therefrom that have not been so
applied by the end of such Reinvestment Period, at which time a prepayment or
reduction of Commitments shall be required in an amount equal to such Net
Proceeds that have not been so applied; PROVIDED FURTHER that, subject to the
last sentence of this paragraph, as a condition to any election by Holdings
pursuant to the immediately preceding proviso (except with respect to any such
election that is contemplated by the parenthetical to clause (b) of the
definition of the term "Reinvestment Period"), the Loan Parties shall deposit
with the Collateral Agent an amount in cash equal to the amount of Net Proceeds
with respect to which such election is being made (less the amount of such Net
Proceeds, if any, already reinvested as provided above), which amount shall be
held by the Collateral Agent as Collateral. At or prior to the end of any
Reinvestment Period referred to above, Holdings may deliver to the Collateral
Agent either (i) a certificate (or, from time to time, certificates) of a
Financial Officer certifying that the Net Proceeds so deposited by it and held
as Collateral (or a portion thereof specified in such certificate) are to be
released and applied for the purposes specified above, which certificate shall
set forth a reasonably detailed description of the application thereof, attach
invoices or receipts to be paid or reimbursed with the funds so released and
certify that a Notice of Enforcement is not in effect and no Secured Party is
entitled to deliver a Notice of Enforcement at the time (in which case such Net
Proceeds or the specified portion thereof, as applicable, shall be released by
the Collateral Agent for such purpose) or (ii) a written notice to the effect
that Holdings has determined not to so apply such Net Proceeds (or a portion
thereof specified in such notice) and directing the Collateral

                                       52
<PAGE>

Agent to release such Net Proceeds (or such portion thereof) for application to
make prepayments and reductions of Commitments in accordance with paragraphs (f)
and (g) below in an equivalent amount (in which case such Net Proceeds or the
specified portion thereof, as applicable, shall be released by the Collateral
Agent for such purpose). If a Prepayment Event described in clause (a) or (b) of
the definition of the term "Prepayment Event" occurs prior to the Effective Date
and Holdings makes the election referred to in the second proviso to the first
sentence of this Section, Holdings will not be required as a condition to such
election to deposit Net Proceeds from such event with the Collateral Agent as
contemplated by the third proviso to such sentence if such Net proceeds are
received prior to the Effective Date; PROVIDED that any such Net Proceeds so
received and not reinvested as contemplated hereby prior to the Effective Date
shall be deposited with the Collateral Agent on the Effective Date pursuant to
such third proviso.

                  (c) In the event and on each occasion that any Net Proceeds
are received by or on behalf of any Loan Party in respect of any IRU
Transaction, the Borrower shall, substantially simultaneously with the receipt
of such Net Proceeds, prepay Borrowings and Other Senior Secured Indebtedness
and reduce Commitments in accordance with paragraphs (f) and (g) below in an
aggregate principal amount equal to 50% of such Net Proceeds; PROVIDED that no
such prepayment shall be required in respect of the first $20,000,000 of Net
Proceeds in respect of IRU Transactions received by the Loan Parties during any
fiscal year of Holdings. Notwithstanding the foregoing, if Holdings elects by
notice to the Administrative Agents at least 30 days prior to the commencement
of a fiscal year of Holdings that the provisions of this sentence will apply for
such fiscal year in lieu of the provisions of the immediately preceding
sentence, then (for such fiscal year), in lieu of the provisions of the
immediately preceding sentence, the Borrower shall, within 10 Business Days
after the end of each of the first six-month period and the second six-month
period of such fiscal year, prepay Borrowings and Other Senior Secured
Indebtedness and reduce Commitments in accordance with paragraphs (f) and (g)
below in an aggregate principal amount equal to 50% of the excess, if any, of
(i) the Net Proceeds in respect of IRU Transactions received by the Loan Parties
during such six-month period over (ii) the sum of $5,000,000 plus the amount of
cash payments made by the Loan Parties to acquire IRUs during such six-month
period.

                  (d) In the event and on each occasion that any Net Proceeds
are received by any Loan Party in respect of any Prepayment Event described in
clause (c) of the definition of the term "Prepayment Event", the Borrower shall,
substantially simultaneously with the receipt of such Net Proceeds, prepay
Borrowings and Other Senior Secured Indebtedness and reduce Commitments in
accordance with paragraphs (f) and (g) below in an

                                       53
<PAGE>

aggregate principal amount equal to the product of (i) the amount of such Net
Proceeds and (ii) the applicable Capital Markets Percentage.

                  (e) Following the end of each fiscal year of Holdings,
commencing with the fiscal year ending on December 31, 2004, the Borrower shall
prepay Borrowings and Other Senior Secured Indebtedness and reduce Commitments
in accordance with paragraphs (f) and (g) below in an aggregate principal amount
equal to 50% of Excess Cash Flow for such fiscal year. Each prepayment or
reduction of Commitments pursuant to this paragraph shall be made on or before
the date on which financial statements are delivered pursuant to Section 5.01
with respect to the fiscal year for which Excess Cash Flow is being calculated
(and in any event within the period required under Section 5.01 for the delivery
of financial statements with respect to such fiscal year).

                  (f) Any Net Proceeds or other amounts required to be applied
to make prepayments or reduce Commitments pursuant to paragraph (b), (c), (d) or
(e) above shall be applied (i) to prepay or offer to prepay Other Senior Secured
Indebtedness to the extent required by the terms thereof; PROVIDED that (A) the
amount so applied in respect of any Other Senior Secured Indebtedness shall not
exceed its Pro Rata Share of the total amount of Borrowings and Other Senior
Secured Indebtedness required to be prepaid and Commitments required to be
reduced pursuant to paragraph (b), (c), (d) or (e) above, as applicable, (B) in
the case of an Agency Capital Market Transaction arranged by a Supplier, no
amount shall be applied to prepay any Other Senior Secured Indebtedness and (C)
if Other Senior Secured Indebtedness with a maturity of two years or less is
incurred to construct or acquire the OSS, then no amount shall be applied to
prepay such Other Senior Secured Indebtedness, and (ii) otherwise (including any
amounts offered to prepay any Other Senior Secured Indebtedness, to the extent
such offer is declined) to prepay Borrowings and reduce Commitments in
accordance with the applicable provisions of this Section.

                  (g) Prior to any optional prepayment of Borrowings, the
Borrower shall select the Borrowing or Borrowings to be prepaid and shall
specify such selection in the notice of such prepayment pursuant to paragraph
(h) of this Section; PROVIDED that the Borrower shall select Borrowings to be
prepaid such that each Lender receives its pro rata share of such prepayment
(based on the percentage of the aggregate principal amount of Loans then
outstanding represented by such Lender's Loans). Prior to any mandatory
prepayment of Borrowings or mandatory reduction of

                                       54
<PAGE>

Commitments pursuant to this Section, the Borrower shall select Borrowings to be
prepaid and Commitments to be reduced as follows:

                      (i) the aggregate amount to be applied to prepay
         Borrowings and reduce Commitments under the Participating Credit
         Agreements shall be allocated among the Participating Credit Agreements
         ratably (based on the percentage of the aggregate principal amount of
         Loans and Commitments then outstanding represented by the Loans and
         Commitments under each Participating Credit Agreement); PROVIDED that
         (A) in the case of an Agency Capital Market Transaction arranged by a
         Supplier, the aggregate amount to be applied to prepay Borrowings and
         reduce Commitments as a result of such Agency Capital Market
         Transaction shall be allocated solely to the Participating Credit
         Agreement related to such Supplier's Supply Contract, and (B) if
         Permitted Senior Secured Indebtedness with a maturity of two years or
         less is incurred to construct or acquire the OSS, then the
         Participating Credit Agreement, and the Borrowings and Commitments
         thereunder, in respect of such Permitted Senior Secured Indebtedness
         shall be disregarded for purposes of allocations of mandatory
         prepayments of Borrowings and mandatory reductions of Commitments;

                     (ii) the aggregate amount to be applied to prepay
         Borrowings and reduce Commitments under each Participating Credit
         Agreement (as determined pursuant to clause (i) above) shall be applied
         (A) first, to prepay Borrowings under such Participating Credit
         Agreement in accordance with clause (iii) below, (B) second,
         permanently to reduce Tranche B Commitments under such Participating
         Credit Agreement in accordance with clause (iv) below and (C) third,
         permanently to reduce Tranche A Commitments under such Participating
         Credit Agreement in accordance with clause (iv) below;

                    (iii) the Borrower shall select Borrowings to be prepaid
         under each Participating Credit Agreement such that each Lender
         thereunder receives its pro rata share of such prepayment (based on the
         percentage of the aggregate principal amount of Loans then outstanding
         under such Participating Credit Agreement represented by such Lender's
         Loans under such Participating Credit Agreement); and

                     (iv) the Borrower shall select Commitments of the
         applicable Class to be reduced under each Participating Credit
         Agreement such that the Commitments of such Class of each Lender
         thereunder are reduced ratably (based on the percentage of the
         aggregate principal amount of Commitments of such Class then
         outstanding under such Participating

                                       55

         Credit Agreement represented by such Lender's Commitment of such Class
         under such Participating Credit Agreement).

telephone (confirmed by telecopy) of any prepayment or reduction of Commitments
not later than 11:00 a.m., New York City time, three Business Days before the
date of such prepayment or reduction of Commitments. Each such notice shall be
irrevocable and shall specify the date, the principal amount of each Borrowing
or portion thereof to be prepaid or of the Commitments to be reduced and, in the
case of a mandatory prepayment or reduction of Commitments, a reasonably
detailed calculation of the amount of such prepayment or reduction of
Commitments. Promptly following receipt of any such notice, each Administrative
Agent shall advise the Lenders in its Lender Group of the contents thereof. Each
partial prepayment of Borrowings shall be in an amount that is an integral
multiple of $1,000,000 and not less than $3,000,000, except as necessary to
apply fully the required amount of a mandatory prepayment. Each prepayment of a
Borrowing shall be applied ratably to the Loans included in the prepaid
Borrowing (except as necessary to allocate prepayments in accordance with the
other requirements of this Agreement). Prepayments of Borrowings shall be
accompanied by the payment of accrued interest on the amount prepaid.

business or the ownership, leasing or holding of its property makes such
qualification necessary.

                  SECTION 3.02. AUTHORIZATION; ENFORCEABILITY. The Transactions
entered into or to be entered into by each Loan Party are within such Loan
Party's powers and have been duly authorized (or, in the case of any Restricted
Subsidiary, will have been duly authorized as of the Effective Date) by all

                                       56
<PAGE>

necessary corporate and, if required, shareholder action. This Agreement has
been duly executed and delivered by Holdings and the Borrower and constitutes a
legal, valid and binding obligation of Holdings and the Borrower, and each other
Loan Document and Project Document to which any Loan Party is or is to be a
party constitutes (or, when executed and delivered by it, will constitute) a
legal, valid and binding obligation of such Loan Party, in each case enforceable
in accordance with its terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium or other laws affecting creditors' rights generally,
subject to general principles of equity, regardless of whether considered in a
proceeding in equity or at law.

                  SECTION 3.03. GOVERNMENTAL APPROVALS; NO CONFLICTS. (a) The
Transactions, the build-out, maintenance, installation and operation of the
Network, the development of the Project and the execution, delivery and
performance of the Project Documents (i) do not require any material
Governmental Approvals, except (A) such as have been obtained or made and are in
full force and effect, (B) filings necessary to perfect Liens created under the
Security Documents, (C) the Governmental Approvals described on Schedules 3.03
and 3.19 and (D) any Permitted Additional Governmental Approvals, (ii) will not
violate any applicable law or regulation or the charter, by-laws or other
organizational documents of any Loan Party or any order of any Governmental
Authority, (iii) will not violate or result in a default under any indenture,
material agreement or other material instrument binding upon any Loan Party or
its assets, or give rise to a right thereunder to require any payment to be made
by any Loan Party (except in respect of Existing AT&T Financings prior to the
Effective Date), and (iv) will not result in the creation or imposition of any
Lien on any asset of any Loan Party, except Liens created under the Security
Documents and Permitted Encumbrances.

                  (b) Schedule 3.03 sets forth all material Governmental
Approvals (other than the Concessions and Permitted Additional Governmental
Approvals) required in connection with the Transactions, the build-out,
maintenance, installation and operation of the Network, the development of the
Project and the execution, delivery and performance of the Project Documents,
including Governmental Approvals required in order to permit payments to be made
in respect of principal of and interest on Local Financing Loans and in respect
of the Obligations. Except as expressly set forth in Schedule 3.03, all
Governmental Approvals set forth therein have been obtained, made or taken (as
the case may be) and are valid and in full force and effect, and each of the
Loan Parties is in compliance with the terms and conditions thereof, except
where the failure so to comply would not, individually or in the aggregate, be
reasonably expected to have a Material Adverse Effect. Each of the Borrower and

                                       57
<PAGE>

Holdings reasonably believes that any such Governmental Approval that has not
been obtained, made or taken (as the case may be) will be obtained, made or
taken in due course at or prior to the time when needed, free from any
conditions or requirements that cannot be satisfied and compliance with which
would not be reasonably expected to have a Materially Adverse Effect.
Notwithstanding any of the foregoing provisions of this paragraph, no
representation is made in this paragraph with respect to any Governmental
Approvals that may be required to satisfy the Argentina Payment Condition.

                  SECTION 3.04. FINANCIAL CONDITION; NO MATERIAL ADVERSE CHANGE.
(a) Holdings has heretofore furnished to the Lenders its consolidated balance
sheet and statements of income, stockholders' equity and cash flows (i) as of
and for the fiscal year ended December 31, 2000, reported on by
PricewaterhouseCoopers LLP, independent public accountants, and (ii) as of and
for the nine month period ended September 30, 2001, certified by a Financial
Officer. Such financial statements present fairly, in all material respects, the
financial position and results of operations and cash flows of Holdings and its
consolidated subsidiaries as of such dates and for such periods in accordance
with GAAP, consistently applied, subject to year-end audit adjustments and the
absence of footnotes in the case of the statements referred to in clause (ii)
above. The Borrower has heretofore furnished to the Lenders its balance sheet as
of September 30, 2001, certified by a Financial Officer. Such balance sheet
presents fairly, in all material respects, the financial position of the
Borrower as of such date in accordance with GAAP, subject to year-end audit
adjustments and the absence of footnotes. Neither Holdings, the Borrower nor any
of the Restricted Subsidiaries had, as of the date of any such financial
statements, any material contingent liabilities, material liabilities for Taxes
or material long-term leases, material forward or long-term commitments or
material unrealized losses from any unfavorable commitments that are not
reflected in the foregoing statements or in the notes thereto or in publicly
available filings either made by Holdings with the SEC at least 30 days prior to
the date of this Agreement or delivered to the Initial Lenders.

                  (b) Since March 31, 2001, there has been no change, event,
development or circumstance that has had or would be reasonably expected to have
a Material Adverse Effect.

                  (c) The projected consolidated statements of income and cash
flow of Holdings and its consolidated subsidiaries for the period from calendar
year 2001 to and including calendar year 2008, and the projected annual
consolidated balance sheets of Holdings and its consolidated subsidiaries as of
the last day of each fiscal year, each as included in the Business Plan (copies
of which have been furnished to the Lenders), have been prepared

                                       58
<PAGE>

in good faith on the basis of assumptions believed to be reasonable as of the
date of preparation thereof.

                  SECTION 3.05. PROPERTIES. (a) Holdings, the Borrower and each
of the Restricted Subsidiaries has good title to, or valid leasehold interests
in, all the real and personal property material to its business free and clear
of all Liens (other than Liens permitted under Section 6.02), except for minor
defects in title that do not interfere with its ability to conduct its business
as currently conducted or proposed to be conducted.

                  (b) Holdings, the Borrower and each of the Subsidiaries owns,
or is licensed or otherwise has the right to use, all trademarks, trade names,
copyrights, patents and other intellectual property material to its business,
and the use thereof by Holdings, the Borrower and the Subsidiaries does not
infringe upon the rights of any other Person, except for any such infringements
that, individually or in the aggregate, would not be reasonably expected to
result in a Material Adverse Effect.

                  (c) Schedule 3.05 (as supplemented by any supplements thereto
delivered to the Agents prior to the Effective Date) sets forth the address of
each real property that is owned or leased by Holdings, the Borrower or any of
the Subsidiaries as of the Effective Date and indicates any such owned real
property with a fair market value in excess of $1,000,000, or leased property at
which is located tangible assets with a fair market value in excess of
$1,000,000, in each case as determined by Holdings in good faith. As of the
Effective Date, neither Holdings, the Borrower nor any of the Subsidiaries has
received notice of, or has knowledge of, any pending or contemplated
condemnation or similar proceeding affecting any Mortgaged Property or any sale
or disposition thereof in lieu of condemnation. Neither any Mortgaged Property
nor any material interest therein is subject to any right of first refusal,
option or other contractual right to purchase such Mortgaged Property or
interest therein.

                  SECTION 3.06. LITIGATION AND ENVIRONMENTAL MATTERS. (a) There
are no actions, suits or proceedings by or before any arbitrator or Governmental
Authority pending against, (to its knowledge) threatened against or (to its
knowledge) affecting Holdings, the Borrower or any of the Subsidiaries, or (to
their knowledge) seeking to nullify, rescind, terminate, modify or suspend any
Concession or other Governmental Approval set forth on Schedule 3.03 (i) as to
which there is a reasonable possibility of an adverse determination and that, if
adversely determined, would be reasonably expected, individually or in the
aggregate, to result in a Material Adverse Effect or (ii) that challenge the
validity, enforceability or effectiveness of any of the Loan Documents, the
borrowing of the Loans or the use of the proceeds thereof.

                                       59
<PAGE>

                  (b) Except for the Disclosed Matters and except with respect
to any other matters that, individually or in the aggregate, would not be
reasonably expected to result in a Material Adverse Effect, neither Holdings,
the Borrower nor any of the Subsidiaries (i) has failed to comply with any
applicable Environmental Law or to obtain, maintain or comply with any
Governmental Approval required under any applicable Environmental Law, (ii) has
become subject to any Environmental Liability, (iii) has received notice of any
claim with respect to any Environmental Liability or (iv) knows, on the basis of
the most recent information available to it, of any basis for any Environmental
Liability.

                  (c) Since the date of this Agreement, there has been no change
in the status of the Disclosed Matters that, individually or in the aggregate,
has resulted in, or materially increased the likelihood of, a Material Adverse
Effect.

                  SECTION 3.07. COMPLIANCE WITH LAWS AND AGREEMENTS. Holdings,
the Borrower and each of the Subsidiaries is in compliance with all laws,
regulations, orders, judgments and decrees of any Governmental Authority
applicable to it or its property and all indentures, agreements and other
instruments binding upon it or its property, except where the failure to do so,
individually or in the aggregate, would not be reasonably expected to result in
a Material Adverse Effect. No Default has occurred and is continuing.

                  SECTION 3.08. INVESTMENT AND HOLDING COMPANY STATUS. None of
the Loan Parties is (a) an "investment company" subject to regulation under the
Investment Company Act of 1940, (b) a "holding company" as defined in, or
subject to regulation under, the Public Utility Holding Company Act of 1935 or
(c) subject to any similar law or regulation restricting its ability to incur
Indebtedness.

                  SECTION 3.09. TAXES. Each of the Loan Parties has timely filed
or caused to be filed all material Tax returns and reports required to have been
filed and has paid or caused to be paid all material Taxes required to have been
paid by it, except where (a) the validity or amount thereof is being contested
in good faith by appropriate proceedings, (b) the applicable Loan Party has set
aside on its books adequate reserves in accordance with GAAP, (c) such contest
effectively suspends collection of such Taxes and the enforcement of any Lien
securing such obligations and (d) the failure to so file or make payment pending
the resolution of such contest would not reasonably be expected to result in a
Material Adverse Effect. There has not been asserted or proposed to be asserted
any material Tax deficiency against any Loan Party or for which any Loan Party
may be liable for which an adequate reserve in accordance with GAAP has not been
set aside on the books of the applicable Loan Party.

                                       60
<PAGE>

                  SECTION 3.10. DISCLOSURE. Holdings and the Borrower have
disclosed to the Lenders (directly or indirectly through their counsel or
agents) all agreements, instruments and corporate or other restrictions to which
any of the Loan Parties is subject, and all matters otherwise known to either of
them, that, individually or in the aggregate, would be reasonably expected to
result in a Material Adverse Effect. None of the reports, financial statements,
certificates or other information furnished by or on behalf of any Loan Party to
any Agent or any Lender in connection with the negotiation of this Agreement or
any other Loan Document or delivered hereunder or thereunder (as modified or
supplemented by other information so furnished) contains any material
misstatement of fact or omits to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading; PROVIDED that, with respect to projected financial
information, Holdings and the Borrower represent only that such information was
prepared in good faith on the basis of assumptions believed to be reasonable at
the time.

                  SECTION 3.11. SUBSIDIARIES. Schedule 3.11 (as supplemented by
any supplements thereto delivered to the Administrative Agents prior to the
Effective Date) sets forth as of the Effective Date the name of, and the
ownership interest of Holdings in, each Subsidiary, indicating with respect to
each such Subsidiary its status as a Restricted Subsidiary or an Unrestricted
Subsidiary and its jurisdiction of organization. Each Subsidiary listed on
Schedule 1.01(b) as an Unrestricted Subsidiary (a) does not hold any material
assets, (b) does not conduct any material operations and (c) satisfies the
criteria set forth in clauses (a) through (h) (other than clause (e)) of Section
8.13.

                  SECTION 3.12. INSURANCE. Schedule 3.12 (as supplemented by any
supplements thereto delivered to the Agents prior to the Effective Date) sets
forth a description of all insurance maintained by or on behalf of the Loan
Parties as of the Effective Date. As of the Effective Date, premiums due and
payable in respect of such insurance have been paid. Holdings and the Borrower
believe that the insurance maintained by or on behalf of the Loan Parties is
adequate and complies with the insurance requirements contained herein and in
the other Loan Documents.

                  SECTION 3.13. SUPPLY CONTRACTS. As of the Effective Date, each
Supply Contract is in full force and effect. As of the date of each Borrowing
under any Participating Credit Agreement (a) the Supply Contract related to such
Participating Credit Agreement is in full force and effect and (b) except for
any termination in compliance with this Agreement, each other Supply Contract is
in full force and effect. As of the Effective Date and the date of each such
Borrowing, Holdings and each

                                       61
<PAGE>

applicable Restricted Subsidiary is in compliance in all material respects with
the terms and conditions of each Supply Contract.

                  SECTION 3.14. NO IMMUNITY DEFENSE. Each of the Loan Parties is
subject to private commercial law and suit, and no Loan Party is entitled to
sovereign immunity under any such laws. Neither the Loan Parties nor their
respective assets have the right of immunity from suit, attachment or execution
on the grounds of sovereignty within the Netherlands, any Project Country or in
any other jurisdiction. Under the Laws of Argentina, none of the Loan Parties
nor any asset of any Loan Party has any immunity from jurisdiction of any court
or from setoff or any legal process (whether through service or notice,
attachment prior to judgment, attachment in aid of execution, attachment,
execution or otherwise), nor are any such assets considered assets pertaining to
the rendering of a public service.

                  SECTION 3.15. OWNERSHIP OF HOLDINGS. To the best knowledge of
Holdings, Schedule 3.15 identifies each Person that, as of the Closing Date,
beneficially or of record owns Equity Interests in Holdings representing 5% or
more of the ordinary voting power or the equity value represented by all Equity
Interests in Holdings outstanding as of the Closing Date. The total number of
shares of capital stock of Holdings that are subject to options, warrants and
other stock purchase rights outstanding as of the Closing Date does not exceed
20,000,000.

                  SECTION 3.16. PROJECT DOCUMENTS, ETC. Schedule 3.16 (as
supplemented by any supplements thereto delivered to the Administrative Agents
prior to the Effective Date) includes all the Project Documents in effect as of
the Effective Date. The documents identified on Schedule 3.16 constitute and
include all material contracts and agreements necessary for the construction,
installation and operation of the Project as contemplated as of the Effective
Date and in a manner consistent with the Business Plan and applicable law, in
each case to the extent reasonably foreseeable as of the Effective Date.
Holdings has delivered to the Lenders true and correct copies of each Project
Document in effect as of the Effective Date (subject to redaction to exclude
information that any Loan Party is not permitted to disclose by reason of
binding confidentiality obligations imposed on such Loan Party pursuant to the
terms thereof). Neither any Loan Party nor any other party to any Project
Document is in default in the performance of any obligation set forth in such
Project Document that would reasonably be expected to result in a Material
Adverse Effect. No event has occurred that would reasonably be expected to give
rise to the termination of any Project Document that would reasonably be
expected to result in a Material Adverse Effect. All conditions precedent to the
obligations of the respective parties to each Project Document have been waived
or satisfied, except for any such conditions

                                       62
<PAGE>

that are not to be met until a later stage of the implementation of the Project,
and Holdings reasonably believes that any such condition to be satisfied in the
future will be satisfied at or prior to the time required.

                  SECTION 3.17. WITHHOLDING AND OTHER TAXES. As of the Closing
Date and as of the Effective Date, other than as set forth on Schedule 3.17 to
the Disclosure Letter (as supplemented by any supplements thereto delivered to
the Administrative Agents prior to the Effective Date), there is no material
tax, levy, impost, deduction, charge or withholding imposed, levied or made by
or in any Project Country or the Netherlands or any political subdivision or
taxing authority thereof or therein (i) on or by virtue of the execution,
delivery, performance, enforcement or admissibility into evidence of this
Agreement or any of the other Loan Documents or (ii) on or in respect of any
payment to be made by the Borrower or any Restricted Subsidiary pursuant to this
Agreement or any of the other Loan Documents.

                  SECTION 3.18. RANKING OF LOANS. The obligations of each Loan
Party under the Loan Documents rank in right of payment at least PARI PASSU with
all other senior Indebtedness for borrowed money of such Loan Party.

                  SECTION 3.19. CONCESSIONS. Schedule 3.19 (as supplemented by
any supplements thereto delivered to the Administrative Agents prior to the
Effective Date) sets forth all of the Concessions, as of the Closing Date and as
of the Effective Date, and the name of the Loan Party holding each such
Concession. Each of the Concessions is valid and in full force and effect
(except as set forth in Schedule 3.19), and the Loan Parties are in compliance
in all material respects with the terms and conditions thereof. The rights
granted to the Loan Parties pursuant to the Concessions, together with the other
Governmental Approvals set forth on Schedule 3.03 (and any Permitted Additional
Governmental Approval), provide the Loan Parties with adequate rights to enable
the Loan Parties to operate the Project.

                  SECTION 3.20. BUILD AND COVERAGE REQUIREMENTS. Except as set
forth on Schedule 3.20 and except for requirements attributable to changes in
circumstances after the Closing Date that would not reasonably be expected,
individually or in the aggregate, to have a Material Adverse Effect, no Loan
Party is required by the terms of any Concession or other Governmental Approval
or by any applicable law, rule, regulation or other requirement of any
Governmental Authority to (a) provide or make available any telecommunications
service to any Person or in any geographic region, (b) make any
telecommunications service generally available in any Project Country or (c)
install any telecommunications equipment, build or cause to be built any

                                       63
<PAGE>

telecommunications network or otherwise make any Capital Expenditure.

                  SECTION 3.21. SECURITY DOCUMENTS. On and after the Effective
Date, the Security Documents create in favor of the Collateral Agent or, where
specified, the Lenders, for the benefit of the Secured Parties, legal, valid,
binding and enforceable Liens in all Collateral as specified therein, subject to
applicable bankruptcy, insolvency, reorganization, moratorium or other laws
affecting creditors' rights generally and subject to general principles of
equity, regardless of whether considered in a proceeding in equity or at law.
The Liens granted under each Security Document are perfected and are prior to
any other Liens on the Collateral referred to therein, except in each case as
permitted by the terms of, and subject to the exceptions set forth in, the Loan
Documents.

                  SECTION 3.22. SOLVENCY. Immediately after the consummation of
the Transactions to occur on the Effective Date and immediately following the
making of each Loan and after giving effect to the application of the proceeds
of such Loans (and taking into account all rights of contribution arising by
operation of law or otherwise to which any Loan Party may be entitled and other
credit support available to any Subsidiary from Holdings, any of the other
Subsidiaries or the Borrower or available to the Borrower from Holdings or any
Subsidiaries), (a) the fair value of the assets of each Loan Party, at a fair
valuation, will exceed its debts and liabilities, subordinated, contingent or
otherwise, (b) the present fair saleable value of the property of each Loan
Party will be greater than the amount that will be required to pay the probable
liability of its debts and other liabilities, subordinated, contingent or
otherwise, as such debts and other liabilities become absolute and matured, (c)
each Loan Party will be able, generally, to pay its debts and liabilities,
subordinated, contingent or otherwise, as such debts and liabilities become
absolute and matured, (d) each Loan Party will not have unreasonably small
capital with which to conduct the business in which it is engaged as such
business is now conducted and is proposed to be conducted following the
Effective Date and (e) the Argentine Operating Subsidiary's financial condition
will be consistent with the technical and investment plans described by them in
the application forms for telecommunication licenses and services filed with the
Argentine Governmental Authorities.

                  SECTION 3.23. ERISA. (a) No ERISA Event has occurred or is
reasonably expected to occur that, when taken together with all other such ERISA
Events for which liability is reasonably expected to occur, would reasonably be
expected to result in a Material Adverse Effect. The present value of all
accumulated benefit obligations under each Plan (based on the assumptions used
for purposes of Statement of Financial Accounting Standards

                                       64
<PAGE>

No. 87) did not in the aggregate, as of the date of the most recent financial
statements reflecting such amounts, exceed the fair market value of the assets
of such Plan by an amount by more than $1,000,000, and the present value of all
accumulated benefit obligations of all underfunded Plans (based on the
assumptions used for purposes of Statement of Financial Accounting Standards No.
87) did not in the aggregate, as of the date of the most recent financial
statements reflecting such amounts, exceed by more than $1,000,000 the fair
market value of the assets of all such underfunded Plans. None of Holdings, the
Subsidiaries or any other ERISA Affiliate has engaged in a transaction with
respect to any employee benefit plan that would reasonably be expected to result
in a Material Adverse Effect.

                  (b) With respect to each pension or employee benefit scheme or
arrangement mandated by a government other than the United States (a "FOREIGN
GOVERNMENT ARRANGEMENT") and with respect to each employee benefit plan
maintained or contributed to by any Loan Party that is not subject to United
States law (a "FOREIGN BENEFIT PLAN"), any employer and employee contributions
required by law or by the terms of any Foreign Government Arrangement or any
Foreign Benefit Plan have been made, or, if applicable, accrued, in accordance
with normal accounting practices (other than any failure to make or accrue such
contributions that would not reasonably be expected to have a Material Adverse
Effect).

                  SECTION 3.24. FEDERAL RESERVE REGULATIONS. (a) Neither
Holdings, the Borrower nor any of the Subsidiaries is engaged principally, or as
one of its important activities, in the business of extending credit for the
purpose of buying or carrying Margin Stock.

                  (b) No part of the proceeds of any Loan will be used, whether
directly or indirectly, and whether immediately, incidentally or ultimately, for
any purpose that entails a violation of, or that is inconsistent with, the
provisions of the Regulations of the Board, including Regulation T, U or X.

                  SECTION 3.25. LABOR MATTERS. As of the Effective Date, there
are no material strikes, lockouts or slowdowns against Holdings or any
Restricted Subsidiary pending or threatened. The hours worked by and payments
made to employees of Holdings and the Restricted Subsidiaries have not been in
violation in any material respect of the Fair Labor Standards Act or any other
applicable Federal, state, local or foreign law dealing with such matters. All
material payments due from Holdings or any Restricted Subsidiary, or for which
any claim may be made against Holdings or any Restricted Subsidiary, on account
of wages and employee health and welfare insurance and other benefits, have been
paid, including all payments required by the Labor Code of Colombia and by any
union agreement or collective

                                       65
<PAGE>

pact, including payments for night work, overtime day work, overtime night work,
work performed on Sundays or legal holidays, severance pay and interest on
severance pay, semester bonus, vacation, transfer expenses indemnities, and
payroll taxes, or (to the extent required by GAAP or generally accepted
accounting principles in effect in the applicable Project Country) accrued as a
liability on the books of Holdings or such Restricted Subsidiary. None of
Holdings or the Restricted Subsidiaries has any outstanding material obligations
relating to Peruvian Workers Time Service Compensation (CTS), Workers Social
Benefits or Private or Public Pensions. The consummation of the Transactions
will not give rise to any right of termination or right of renegotiation on the
part of any union or individual employee under any collective bargaining
agreement to which Holdings or any Restricted Subsidiary is bound. Holdings and
the Restricted Subsidiaries have performed all medical examinations required by
Colombian law or by any union agreement or collective pact, have affiliated all
of their personnel to the Integral Social Security System of Colombia and have
made the payments and contributions to the Integral Social Security System of
Colombia, except where the failure to do so would not reasonably be expected to
result in a Material Adverse Effect. No labor law in Argentina, including the
Labor Contract Law No. 20,744 as amended ("Ley de Contrato de Trabajo No.
20.744"), the Labor Risk Law No. 24,557 ("Ley de Riesgos de Trabajo No. 24.557")
and the National Employment Law No. 24,013 ("Ley Nacional de Empleo No. 24.103")
has been violated in any material respect or is being violated in connection
with employees of Holdings and the Restricted Subsidiaries. Holdings and the
Restricted Subsidiaries control independent contractors' compliance with the
labor and social security obligations related to the independent contractors'
employees in all material respects according to Section 30 of the Labor Contract
Law in Argentina. There are no material labor claims from employees of such
contractors against Holdings or any Restricted Subsidiary pending or threatened,
under which the employees of such contractors argue that Holdings or any
Restricted Subsidiary is jointly and severally liable for any labor or social
security obligations. There are no material pending or threatened claims from
independent professionals of unregistered labor relationships against Holdings
or any Restricted Subsidiary. Each Chilean Subsidiary has entered into a written
employment contract with each of its employees pursuant to the provisions of the
Chilean Labor Code and is not in violation in any material respect of the
Chilean Labor Code or any other labor related laws.

                  SECTION 3.26. AFFILIATE TRANSACTIONS. As of the Closing Date,
except as set forth on Schedule 3.26, no Loan Party is party to any contract or
legally binding arrangement with any Affiliate that is not a Loan Party.

                                       66
<PAGE>

                  SECTION 3.27. LOCAL FACILITIES INDEBTEDNESS. Schedule 1.01(d)
sets forth all Local Facilities Indebtedness existing as of the Closing Date.

                                   ARTICLE IV
                                   CONDITIONS

                  SECTION 4.01. EFFECTIVE DATE. The obligations of each Initial
Lender to make Loans under its Initial Participating Credit Agreement shall not
become effective until the date on which each of the following conditions is
satisfied (or waived in accordance with Section 8.02):

                  (a) The Administrative Agents (or their counsel) shall have
         received from each party hereto or thereto a counterpart of this
         Agreement and each Initial Participating Credit Agreement signed on
         behalf of such party and promissory notes for each Lender as required
         by the Initial Participating Credit Agreements. Each Initial
         Participating Credit Agreement shall be reasonably satisfactory in form
         and substance to the Administrative Agents and Initial Lenders that are

such change) (i) in any Loan Party's corporate name or in any trade name used to
identify it in the conduct of its business or in the ownership of its
properties, (ii) in the location of any Loan Party's chief executive office or

                  (b) Holdings and the Borrower agree not to effect or permit
any change referred to in the preceding paragraph or any change in the location
where any asset constituting Collateral is installed or situated (including the
installation of any asset constituting Collateral (other than CPE) at a location

actions have been made or taken that are required, in connection with or as a
result of such change, in order for the Collateral Agent to continue at all
times following such change to have a valid, legal and perfected Lien in all the
Collateral. Holdings and the Borrower also agree promptly to notify the

                                       77
<PAGE>

Agents if any material portion of the Collateral is damaged or destroyed.

                  (c) Each year, at the time of delivery of annual financial

containing a description of the Collateral have been filed of record in each
governmental, municipal or other appropriate office in each jurisdiction to the
extent necessary to protect and perfect the Liens under the Security Documents
for a period of not less than 18 months after the date of such certificate
(except as noted therein with respect to any documents or instruments to be

                  (d) Holdings shall maintain records with respect to the

in default, except where (a) the validity or amount thereof is being contested
in good faith by appropriate proceedings, (b) Holdings, the Borrower or such
Restricted Subsidiary has set aside on its books adequate reserves with respect
thereto in accordance with GAAP, (c) such contest effectively suspends
collection of the contested obligation and the enforcement of any Lien securing
such obligation and (d) the failure to make payment pending the resolution of
such contest would not reasonably be expected to result in a Material Adverse
Effect.

                  SECTION 5.06. MAINTENANCE OF PROPERTIES. Each of Holdings and
the Borrower will, and Holdings will cause each of the Restricted Subsidiaries
to, keep and maintain all property

         repair or replacement of the Object or part thereof;

                  (iii) business interruption insurance covering risk of loss as
         a result of physical damage to the property of the Loan Party required
         to be insured under clause (i) or (ii) above, which provides for the

         the applicable Loan Parties, less any noncontinuing costs and expenses
         attributable to the accident (gross earnings form); and

                  (iv) third-party liability insurance for bodily injury and

                  1.       Any object which is being or has been manufactured

substance reasonably satisfactory to the Administrative Agents, which shall
provide that all insurance proceeds (x) in excess of $2,000,000 or (y) payable
at any time that an Event of Default shall be continuing shall be payable
directly to the Collateral Agent on behalf of all the Secured Parties and held
as Collateral. Holdings may deliver to the Collateral Agent a certificate (or,
from time to time, certificates) of a Financial Officer

                                       80
<PAGE>

certifying that such insurance proceeds held as Collateral (or a portion thereof
specified in such certificate) are to be released and applied for repair or
replacement of the affected assets or to reimburse the applicable Loan Party
therefor, which certificate shall certify that a Notice of Enforcement is not in
effect and no Secured Party is entitled to deliver a Notice of Enforcement at
the time (in which case such Net Proceeds or the specified portion thereof, as
applicable, shall be released by the Collateral Agent for such purpose). Each
policy required under Section 5.07(b), or certificate evidencing such policy,
also shall (i) provide that it shall not be canceled, reduced in amount,
materially adversely modified in coverage or otherwise, or not renewed for any
reason except upon not less than 30 days' prior written notice thereof (except
in the event of the nonpayment of a premium, in which case the requirement of
not less than 10 days' prior written notice thereof shall apply) by the insurer
to the Agents and (ii) provide that the Secured Parties shall not have any
obligation for liability for premiums, commissions, assessments or calls in
connection with such insurance or in connection with any representation or
warranty made by any Loan Party in connection with obtaining such insurance.
Holdings shall deliver to the Agents, prior to the cancelation, reduction,
materially adverse modification or nonrenewal of any such policy of insurance, a
certificate of insurance from the provider of such renewal or replacement
policy.

                  (d) Holdings shall furnish to each Agent within 30 days after
each policy anniversary, or as requested by such Agent from time to time,
certificates of insurance in respect of all insurance required to be maintained
for the next term, stating the names of the insurance companies, the amounts of
insurance, the dates of expiration thereof, the assets and risks covered thereby
and otherwise demonstrating compliance with paragraphs (b) and (c) of this
Section. Such certificates shall (i) be executed by an authorized representative
of each insurer and (ii) certify that such insurance is not subject to
cancelation by the insurer except as permitted hereby.

                  SECTION 5.08. BOOKS AND RECORDS; INSPECTION RIGHTS. (a) Each
of Holdings and the Borrower will, and Holdings will cause each of the
Restricted Subsidiaries to, keep proper books of record and account in which
full, true and correct entries are made, in all material respects, of all
dealings and transactions in relation to its business and activities. Each of
Holdings and the Borrower will, and Holdings will cause each of the Restricted
Subsidiaries to, permit any representatives designated by any Agent or any
Lender, upon reasonable prior notice, to visit and inspect its properties, to
examine and make extracts from its books and records, and to discuss its
affairs, finances and condition with its officers and independent accountants,
all during normal business hours but as often as reasonably

                                       81
<PAGE>

requested; PROVIDED that, so long as no Event of Default has occurred and is
continuing, the Agents and Lenders shall use reasonable efforts to coordinate
any such visits so that interested Agents and Lenders visit as a group rather
than individually and otherwise minimize any disruption to the business of the
Loan Parties and any material burdens on management time.

                  (b) Within 90 days of the end of each fiscal year of Holdings,
representatives of the senior management of Holdings will meet with the Agents
and the Lenders and provide the Agents and the Lenders with such information as
they require with respect to (i) the financial results and other information for
such fiscal year delivered pursuant to Section 5.01, (ii) the status and
progress of the Project, (iii) the Budget required to be delivered pursuant to
clause (f) of Section 5.01 and (iv) such other matters relating to the business,
operations and condition of Holdings, the Borrower and the Subsidiaries as any
Agent or Lender may reasonably request.

                  SECTION 5.09. COMPLIANCE WITH LAWS AND AGREEMENTS; MAINTENANCE
AND ENFORCEMENT OF PROJECT DOCUMENTS. Each of Holdings and the Borrower will,
and Holdings will cause each of the Restricted Subsidiaries to, comply with all
laws, rules, regulations and orders of any Governmental Authority (including all
Environmental Laws) applicable to it or its property and with all indentures,
agreements and other instruments binding upon it or its property (including each
Supply Contract, each Concession, the other Project Documents and each Material
Contract), except where the failure to do so, individually or in the aggregate,
would not reasonably be expected to result in a Material Adverse Effect. Each of
Holdings and the Borrower will, and Holdings will cause each of the Restricted
Subsidiaries to, maintain in full force and effect each of the Project Documents
and diligently enforce, to the fullest extent permitted thereunder, all its
material rights, remedies and benefits under such Project Documents, except
where the failure to do so (individually or in the aggregate) would not
reasonably be expected to result in a Material Adverse Effect; PROVIDED that the
termination of a Supply Contract for any reason set forth in clause (s) of
Section 7.01 shall constitute an Event of Default only as provided in such
clause.

                  SECTION 5.10. USE OF PROCEEDS. The proceeds of Loans under
each Participating Credit Agreement will be used for the purposes specified in
such Participating Credit Agreement.

                  SECTION 5.11. ADDITIONAL SUBSIDIARIES. If any additional
Restricted Subsidiary is formed or acquired after the Effective Date, Holdings
will, within 15 calendar days after such Restricted Subsidiary is formed or
acquired, (a) notify the Agents thereof and (b) cause the Collateral and
Guarantee

                                       82

provided in paragraphs (b), (c), (d) and (e) below, Holdings and the Borrower
will, and Holdings will cause each of the Restricted Subsidiaries to, execute
any and all documents, financing statements, agreements and instruments, and
take all actions, which may be required under any applicable law, or which any
Agent or the Requisite Lenders may reasonably request, to cause the Collateral
and Guarantee Requirement to be and remain satisfied, all at the expense of the
Loan Parties. Holdings and the Borrower also agree to provide to the Agents,
from time to time upon request, evidence reasonably satisfactory to the
Administrative Agents as to the perfection and priority of the Liens created or
intended to be created by the Security Documents.

                  (b) If any assets (excluding any real property or improvements
thereto or any interest therein and accounts receivable) are acquired by
Holdings or any Restricted Subsidiary after the Effective Date, Holdings will,
on the earlier of (i)(A) during the Availability Period, the most recent
two-month anniversary of the Effective Date or (B) after the Availability
Period, the most recent three-month anniversary of the Effective Date and (ii)
the date on which the aggregate cost of such assets acquired since the previous
such notification exceeds $10,000,000, notify the Agents thereof, and Holdings
will cause such assets to be subjected to a perfected Lien securing the
Obligations (to the extent required to satisfy the Collateral and Guarantee
Requirement) and will take, and will cause the Restricted Subsidiaries to take,
such actions as shall be necessary or reasonably requested by any Agent to grant
and perfect such Liens, including actions described in paragraph (a) of this
Section, all at the expense of the Loan Parties; PROVIDED that, if an Event of
Default has occurred and is continuing, Holdings will take, and will cause the
Restricted Subsidiaries to take, any of the foregoing actions immediately upon
request by any Agent; PROVIDED FURTHER that Holdings will take, and will cause
the Restricted Subsidiaries to take, any of the foregoing actions immediately
with respect to any asset the acquisition of which is contemplated by the last
proviso to Section 6.04(b).

                  (c) Holdings will cause the accounts receivable of each Loan
Party to be subjected to a Lien securing the Obligations in accordance with the
requirements of the applicable Security Documents, all at the expense of the
Loan Parties.

grant a Mortgage with respect to each parcel of real

                                       83

extended (except with respect to any renewal or extension effected solely by the
giving of notice to the relevant lessor under the terms of the applicable lease)
after the Closing Date and the sum of the fair market value to the applicable
Loan Party of such leasehold interest plus the aggregate cost of all assets of
any Loan Party (including tenant improvements) located or held at or in such

also shall, and shall cause the Restricted Subsidiaries to, exercise
commercially reasonable efforts to grant a Mortgage with respect to the
applicable Loan Party's rights in each leasehold interest of such Loan Party in
real property and improvements thereto, in each case in favor of the Collateral
Agent or the Lenders, if the lease providing for such leasehold interest was
entered into after the Closing Date and any Network Infrastructure is located or
held at or in such real property or improvements, but a Mortgage is not required
by the preceding sentence.

                  (e) Unless prohibited by applicable law, Holdings or the
Borrower shall (or, with respect to Concessions, Material Contracts and
Governmental Approvals, shall use its commercially reasonable best efforts to),

award or otherwise), the Collateral Agent is authorized and empowered to collect
such Net Proceeds and, if received by any Loan Party, such Net Proceeds shall be
paid over to the Collateral Agent; PROVIDED that, if at the time of such
collection or receipt, an Event of Default shall not have occurred and be
continuing, then such Net Proceeds may be retained by, or paid over to, the Loan
Parties if such Net Proceeds shall not exceed $5,000,000. All such Net Proceeds
retained by or paid over to the Collateral Agent shall be held by the Collateral
Agent as Collateral and released from time to time as provided below to pay the
costs of repairing, restoring or replacing the affected property or purchasing
additional property constituting Collateral in accordance with the terms of this
Agreement and the applicable provisions of the Security Documents, subject to
the provisions of the Security Documents regarding application of such Net
Proceeds during a Default. Holdings may deliver to the Collateral Agent a
certificate (or, from time to time, certificates) of a Financial Officer
certifying that such Net Proceeds held as Collateral (or a portion thereof
specified in such certificate) are to be released and applied for the purposes
specified above, which certificate shall set forth a reasonably detailed
description of the application thereof, attach invoices or receipts to be paid
or reimbursed with the funds so released and certify that a Notice of
Enforcement is not in effect and no Secured Party is entitled to deliver a
Notice of Enforcement at the time (in which case such Net Proceeds or the
specified portion thereof, as

                                       85
<PAGE>

applicable, shall be released by the Collateral Agent for such purpose).

                  (c) If any Net Proceeds retained by or paid over to the
Collateral Agent as provided above continue to be held by the Collateral Agent
on the date that any prepayment is due pursuant to Section 2.03(b) in respect of
the event resulting in such Net Proceeds, then such Net Proceeds shall be
applied to prepay Borrowings and Other Senior Secured Indebtedness as provided
in Section 2.03(b).

                  SECTION 5.14. HEDGING. Holdings or the Borrower will from time
to time enter into and maintain in effect interest rate protection agreements,
on such terms and with such parties as shall be reasonably satisfactory to the
Administrative Agents, as shall be necessary so that at all times on and after
the Effective Date at least 50% of Total Indebtedness (including, for this
purpose, Subordinated AT&T Indebtedness, but excluding contingent obligations
and obligations under Hedging Agreements) shall be comprised of Subordinated
AT&T Indebtedness, Indebtedness bearing interest at a fixed rate or Indebtedness
subject to such interest rate protection agreements. The Loan Parties will from
time to time enter into currency exchange rate protection agreements in such
amounts and with respect to such currencies as are prudent and customary for
similarly situated companies that are subject to similar currency exchange rate
risks.

                  SECTION 5.15. MATERIAL CONTRACTS. Holdings will (a)
irrevocably assign all of its rights and interests under each Material Contract
(other than the Brand License Agreements) to which it is party on the Effective
Date to a Restricted Subsidiary that is a wholly owned Subsidiary, (b) take all
actions necessary to ensure the effectiveness of each assignment required
pursuant to clause (a) of this sentence (including the acquisition of all
required third-party consents thereto) and (c) ensure that, except to the extent
necessary or advisable in the good faith judgment of Holdings, no Loan Party
other than a Restricted Subsidiary becomes party to any Material Contract after
the Effective Date.

                  SECTION 5.16. AT&T FINANCINGS. Holdings will at all times on
and after the Effective Date maintain in effect (and borrowings thereunder shall
be available (other than by reason, at any time, of such facility having been
fully drawn down)) the AT&T Credit Facilities and Series B Preferred Stock on
terms substantially the same as (or, with respect to economic terms, more
favorable to Holdings than) those in effect on the Effective Date; PROVIDED that
Holdings may prepay the AT&T Credit Facilities and Series B Preferred Stock to
the extent permitted under Section 6.06 and the AT&T Subordination Agreement.

                  SECTION 5.17. AVAILABILITY AND TRANSFER OF FOREIGN CURRENCY.
Holdings will ensure that all requisite foreign exchange control registrations,
approvals and other authorizations, if any, by Argentina, Brazil, Chile,
Colombia, Peru, the Netherlands, or any Governmental Authority therein will be
kept current and in full force and effect, or will be obtained as may be
necessary from time to time, to assure the ability of each Loan Party to
purchase and transfer Dollars to enable such Loan Party to satisfy all its
obligations under the Loan Documents in accordance with their respective terms;
PROVIDED, that the foregoing shall not be construed to require that the
Argentina Payment Condition be satisfied prior to June 30, 2003 or (ii) the
earliest date after the Effective Date on which it becomes reasonably
practicable to satisfy such condition.

                  SECTION 5.18. CENTRAL BANKS. (a) Holdings will cause each
applicable Loan Party to obtain the issuance by each applicable Central Bank of
a certificate of registration or similar evidence (the "REGISTRATION
CERTIFICATE") indicating the amount and the payment dates of each payment of
principal, interest, fees and expenses payable under the Local Financing Loans
no more than 30 days from each date the proceeds of the Local Financing Loans
shall have entered a Project Country or shall have been disbursed abroad in
accordance with the applicable exchange regulations, or, in the case of the
Brazilian Operating Subsidiary, the registration of (i) the relevant Local
Financing Loan with the Central Bank of Brazil under the Registration of
Financial Transactions ("Registro de Operacoes Financeiras") ("ROF"), (ii) the
registration with the Central Bank of Brazil under the applicable ROF of the
payment schedule ("Esquema de Pagamento") with respect to the Local Financing
Loan under the relevant Participating Credit Agreement, which will authorize
payments in foreign currency by the Brazilian Operating Subsidiary of principal,
interest, fees and commissions (if any) under the relevant Local Financing Loan,
and (iii) further authorizations from the Central Bank of Brazil for remittances
under the relevant Local Financing Loan prior to, or no more than 120 days from,
each scheduled payment provided in such ROF registration with the Central Bank
of Brazil obtained in connection with the relevant Local Financing Loan
(including in the case of a mandatory prepayment, acceleration or otherwise), in
each case pursuant to Resolution 2770 dated August 30, 2000, and Circular 3027
dated February 22, 2001, in each case issued by the Central Bank of Brazil;
PROVIDED, that the foregoing shall not be construed to require that the
Argentina Payment Condition be satisfied prior to June 30, 2003 or (ii) the
earliest date after the Effective Date on which it becomes reasonably
practicable to satisfy such condition.

                  (b) Holdings will use its best efforts to obtain all further
approvals and authorizations that are necessary to permit all payments from time
to time required under the Loan Documents,

                                       87
<PAGE>

including mandatory prepayments, payments due upon acceleration and payments
under the Guarantee Agreements, to be made as and when due; PROVIDED, that the
foregoing shall not be construed to require that the Argentina Payment Condition
be satisfied prior to June 30, 2003 or (ii) the earliest date after the
Effective Date on which it becomes reasonably practical to satisfy such
condition.

                  SECTION 5.19. NOTARIZATION, CONSULARIZATION AND TRANSLATION.
Each of Holdings and the Borrower will, and Holdings will cause each of the
Restricted Subsidiaries to, at its own expense, take all such actions with
respect to any Loan Document as may be necessary or reasonably requested by any
Agent in the Netherlands, any Project Country and any other jurisdiction in
which any Loan Party is located in order to ensure the validity, admissibility
into evidence or enforceability of the Loan Documents against the Loan Parties
in any such jurisdiction, including any required certification, notarization,
consularization, official translation, notice or filing of Loan Documents;
PROVIDED that the foregoing shall not apply to any translation of any Loan
Document or other document or agreement. Each of Holdings and the Borrower will,
and Holdings will cause each of the Restricted Subsidiaries to, at its own
expense, cause to be prepared and delivered to the Agents such translations of
any of the Loan Documents or other documents or agreements (a) as shall be
necessary in order to comply with the Collateral and Guarantee Requirement and
create and perfect the Liens required thereby or (b) as any Agent shall
otherwise determine to be necessary or desirable in order to ensure the
admissibility into evidence of any of the Loan Documents in connection with the
exercise of rights or remedies thereunder; PROVIDED that any translation
requested by any Agent pursuant to clause (b) above shall not be required to be
completed until the date that is 60 days after the Effective date, in the case
of any such request on or before the Effective Date, or 60 days after the date
of request, in the case of any request thereafter.

                  SECTION 5.20. AFFILIATE AGREEMENTS. All agreements between any
Loan Party, on the one hand, and AT&T (or the AT&T Successor or Permitted
Transferee that assumes AT&T's obligations under the AT&T Subordination
Agreement as provided therein) or any Affiliate of AT&T (or the AT&T Successor
or such Permitted Transferee, as the case may be)(other than another Loan
Party), on the other hand, including with respect to tax sharing, management
fees or sharing of facilities, services or employees ("AFFILIATE AGREEMENTS")
shall be subject to the AT&T Subordination Agreement, except agreements that are
not required to constitute Subordinated Obligations (as defined therein)
pursuant to the terms thereof. Holdings will cause true and correct copies of
all such Affiliate Agreements to be delivered to the Agents.

                                       88
<PAGE>

                  SECTION 5.21. SUPPLY CONTRACTS. Each of Holdings and the
Borrower agrees that it will not, and Holdings agrees not to permit any
Restricted Subsidiary to, on or after the Effective Date, make any cash payment
in respect of any Supply Contract (that is not financed with Loans under the
related Participating Credit Agreement) except to the extent that (a)
substantially simultaneously with such cash payment, a Loan Party makes cash
payments of the same aggregate amount in respect of each other Supply Contract
or (b) Commitments under the applicable Participating Credit Agreement have been
mandatorily reduced in accordance with Section 2.03 and no corresponding
reduction has been made in the purchase commitment under such Supply Contract.

                  SECTION 5.22. LOCAL FINANCING RESTRUCTURING. If a Ratings
Event (as defined below) occurs in respect of any bank or other financial
institution that is acting as Local Financing Bank (or any direct or indirect
parent entity of such bank or financial institution) (the "RATED ENTITY") then
(a) if the Required Total Lenders so request, each of Holdings and the Borrower
will, and Holdings will cause each of the Restricted Subsidiaries to, cooperate
in replacing such bank or financial institution as Local Financing Bank or
otherwise restructure the Local Financing Loans in a manner reasonably
satisfactory to the Required Total Lenders and (b) if any request is made by the
Required Total Lenders as contemplated by the foregoing clause (a), then unless
and until such request is satisfied the Borrower shall not be entitled to
request a Borrowing under a Participating Credit Agreement and no Operating
Subsidiary or Chilean Subsidiary (as the case may be) shall be entitled to
request a borrowing under any Local Financing Documents. For the purposes of
this Section 5.02, "RATINGS EVENT" means, at any time, (i) a reduction of the
Rated Entity's corporate rating from any nationally recognized credit rating
agency to less than "investment grade", or (ii) no nationally recognized credit
rating agency has in effect a corporate rating of the Rated Entity.

                                   ARTICLE VI
                               NEGATIVE COVENANTS

                  Until the Commitments have expired or terminated and the
principal of and interest on each Loan and all fees payable under the
Participating Credit Agreements have been paid in full, each of Holdings and the
Borrower covenants and agrees with the Lenders that:

         commitments to lend Loans, Other Senior Secured Indebtedness and
         unsecured Indebtedness incurred to finance the construction or

         Permitted Senior Secured Indebtedness committed or arranged by any of
         the Suppliers) at any time;

                  (b) Indebtedness existing on the date hereof and set forth in
         Schedule 6.01 (other than any Local Facilities Indebtedness) and
         extensions, renewals and replacements of any such Indebtedness that do
         not increase (except by the amount of any premium or fees incurred in
         connection with such refinancing or replacement) the outstanding
         principal amount thereof or result in an earlier maturity date or
         decreased Weighted Average Life thereof; PROVIDED that neither the
         Existing AT&T Financings nor any other Indebtedness to AT&T or any
         subsidiary thereof shall be permitted by this clause (b) after the
         Effective Date;

                  (c) subject to Section 6.04, Indebtedness of Holdings to the

         Network Infrastructure and to finance leasehold improvements for office
         space, in each case, used in such Restricted Subsidiary's business,
         including Capital Lease Obligations and any Indebtedness assumed in

         acquisition, construction or improvement shall not exceed 100% of the
         cost of such acquisition, construction or improvement or (ii) incurred
         to extend, renew or replace outstanding Indebtedness permitted by this

         all Indebtedness permitted by this clause (e) shall not exceed
         $30,000,000 at any time outstanding;

                  (j) Indebtedness of Holdings or the Borrower incurred pursuant
         to Agency Capital Market Transactions; PROVIDED that (i) all the Net
         Proceeds thereof are applied to repay Loans and Other Senior Secured

<PAGE>

                  (m) Permitted Working Capital Indebtedness; PROVIDED that no
         such Indebtedness shall be permitted until the AT&T Credit Facilities
         are fully drawn; and

                  (n) this Section shall not be construed to restrict the
         execution, delivery and performance of Hedging Agreements otherwise
         permitted by the Loan Documents.

                  If Indebtedness is incurred that would be permitted under more
than one of the clauses of this Section set forth above, Holdings shall be
permitted to allocate such Indebtedness among such clauses for purposes of
determining compliance with this Section. For purposes of determining compliance
with any provision of this Section that limits the amount of Indebtedness
permitted to an amount expressed in Dollars, compliance with such provision
shall be determined on each date that Indebtedness limited thereby is incurred
by reference to the Dollar Equivalent (determined as of such date of incurrence)
of all Indebtedness limited by such provision and that is denominated in a
currency other than Dollars (including any such Indebtedness then being incurred
as well as all other outstanding Indebtedness limited by such provision), and
fluctuations in exchange rates after such date of incurrence until the next date
of incurrence shall be disregarded; PROVIDED that, solely for purposes of
determining compliance with the limit applicable to clause (g) of this Section,
if the Dollar Equivalent of the initial issuance of Brazilian Debentures
complies with such limit as of the date of issuance, then each successive
refinancing or replacement thereof shall be deemed to comply with such limit if
the proceeds of such refinancing or replacement are applied solely to repay
outstanding Indebtedness under such clause.

                  On and after the Effective Date, the borrower in respect of
all Subordinated AT&T Indebtedness and Indebtedness under the Supplemental
Agreement Facility must be Holdings; PROVIDED that a Restricted Subsidiary may
be a borrower of Subordinated AT&T Indebtedness or Indebtedness under the
Supplemental Agreement Facility if (i) such Indebtedness is evidenced by a
promissory note that (A) is pledged to the Collateral Agent by the holder
thereof to secure the Obligations pursuant to a Security Document reasonably
satisfactory to the Administrative Agents, (B) contains terms reasonably
satisfactory to the Administrative Agents providing that immediately upon the
occurrence of an Event of Default, Holdings shall automatically become the sole
obligor in respect of such Indebtedness and such Restricted Subsidiary shall not
have any liability therefor and (C) is executed by Holdings and (ii) such
Restricted Subsidiary is a party to the AT&T Subordination Agreement. If a
Restricted Subsidiary satisfies the foregoing requirements to be a borrower of
Subordinated AT&T Indebtedness or Indebtedness under the Supplemental Agreement
Facility, as applicable, then Holdings may enter into a Guarantee in favor of
the holder of such

                                       92
<PAGE>

Indebtedness providing for Holdings to Guarantee payment thereof to such holder
in the event that such holder is deprived of such Indebtedness as a result of
foreclosure or other exercise of remedies under such Security Document; PROVIDED
that Holdings's obligations under such Guarantee must (x) in the case of a
Guarantee of Subordinated AT&T Indebtedness, also constitute Subordinated AT&T
Indebtedness and (y) in the case of a Guarantee of Indebtedness under the
Supplemental Agreement Facility, be subordinated to the Obligations to the same
extent as such Indebtedness.

                  SECTION 6.02. LIENS. (a) Holdings and the Borrower will not,
nor will Holdings permit any Restricted Subsidiary to, create, incur, assume or
permit to exist any Lien on any property or asset now owned or hereafter
acquired by it, or assign or sell any income or revenues (including accounts
receivable) or rights in respect of any thereof, except:

                  (ii) Permitted Encumbrances;

         Borrower or any Restricted Subsidiary existing on the date hereof and
         set forth in Schedule 6.02; PROVIDED that (A) such Lien shall not apply
         to any other property or asset of Holdings, the Borrower or any
         Restricted Subsidiary and (B) such Lien shall secure only those
         obligations which it secures on the date hereof and permitted
         refinancings and replacements thereof that do not increase the amount
         thereof;

                  (iv) any Lien existing on any property or asset acquired after
         the date hereof prior to the date that such property or asset was first

         existing on any property or asset of any Person that becomes a
         Restricted Subsidiary after the date hereof prior to the time such
         Person becomes a Restricted Subsidiary; PROVIDED that (A) such Lien is
         not created in contemplation of or in connection with such acquisition
         or such Person becoming a Restricted Subsidiary, (B) such Lien shall
         not apply to any other property or assets of Holdings, the Borrower or
         any Restricted Subsidiary and (C) such Lien shall secure only those
         obligations which it secures on the date of such acquisition or the
         date such Person becomes a Restricted Subsidiary, as the case may be,
         and permitted refinancings and replacements thereof that do not
         increase the amount thereof;

                  (v) Liens on tangible assets (and any related software,
         licenses and similar intangible assets, if applicable) not constituting
         Network Infrastructure acquired, constructed or

<PAGE>

         improved by Holdings or a Restricted Subsidiary; PROVIDED that (A) such
         Liens secure only Indebtedness permitted by clause (e) of Section 6.01,
         (B) except in the case of such Liens securing Indebtedness described in
         clause (e)(ii) of Section 6.01, such Liens and the Indebtedness secured
         thereby are incurred prior to or within 90 days after such acquisition
         or the completion of such construction or improvement, (C) the
         principal amount of the Indebtedness secured thereby does not exceed
         100% of the cost of acquiring, constructing or improving such tangible
         assets and (D) such Liens shall not apply to any other property or
         assets of Holdings, the Borrower or any Restricted Subsidiary;

                  (vi) Liens on CPE that arise in the ordinary course of
         business as a result of the installation thereof or other arrangements
         entered into with customers for the use of CPE;

                  (vii) Liens on any Permitted Interest Reserve Account;
         PROVIDED that such Liens secure only obligations in respect of the
         Brazilian Debentures, Brazilian Debenture Refinancing Indebtedness or
         Permitted High-Yield Indebtedness (as applicable) to which such
         Permitted Interest Reserve Account relates;

                  (viii) Liens constituting licenses of intellectual property
         (including patents, trademarks, trade names, service marks, copyrights,
         technology and processes, but excluding rights under the Brand License
         Agreements) by Restricted Subsidiaries to third parties in the ordinary
         course of business and otherwise in compliance with the Loan Documents;

                  (ix) rights in respect of fiber or telecommunications

         hereunder;

                   (x) Liens on Strategic Investments or investments in
         Unrestricted Subsidiaries securing obligations of the entity in which

Expenditures permitted by paragraph (a) above (disregarding any increases

improvements, software and other purchases in connection with the business
activities in which it is permitted to engage); PROVIDED that if any property,
plant or equipment of the Restricted Subsidiaries is located outside of the
Project Countries as a result of the acquisition thereof pursuant to a Permitted
Business Acquisition, then a portion of the Capital Expenditures in each fiscal
year of Holdings that is permitted to be made outside of the Project Cities may
be devoted to the maintenance of such property, plant or equipment. Holdings
will not permit assets initially located in Project Cities to be relocated
outside of Project Cities in a manner that would be inconsistent with the

         voidness, unenforceability, material impairment or adverse modification

         within 30 days after such event, renewed or replaced such Concession or
         Governmental Approval on terms and conditions no less favorable to the
         Loan Parties than the terms and conditions of such renewed or replaced
         Concession or Governmental Approval, (B) no Loan Party has been or will

         connection with the acquisition of the renewal or replacement of such
         Concession or Governmental Approval, (C) the renewal or replacement of
         such Concession or Governmental Approval will permit the Project and
         (D) during such 30-day period, such event does not have a Material

         that would reasonably be expected to result in a Material Adverse
         Effect; PROVIDED that (i) no such suspension shall constitute an Event

         and conditions of such replaced Material Contract and (B) such
         replacement Material Contract will permit the Project;

                  (s) in relation to any Supply Contract, (i) any

                                      119
<PAGE>

         any default or breach by any Loan Party thereunder or (ii) any Loan
         Party shall terminate any Supply Contract; PROVIDED that no such
         termination shall constitute an Event of Default if (A)(1) Holdings has
         executed, within 75 calendar days after such termination, an agreement

         to the Loan Parties than the terms and conditions of such replaced
         Supply Contract and (2) such replacement Supply Contract will enable
         the Loan Parties to complete construction, installation, completion and
         operation of the Project; PROVIDED that, notwithstanding whether the
         conditions described in the foregoing clause (A) are satisfied, such
         termination shall constitute an Event of Default unless all of the
         Commitments under the Participating Credit Agreement relating to such
         Supply Contract shall have been replaced on terms (except, in the case
         of any such Indebtedness held by a financial institution that is a
         Non-Vendor Lender, with respect to interest rates and fees applicable
         thereto) substantially the same as those of the Initial Participating
         Credit Agreements or otherwise reasonably satisfactory to the Requisite
         Lenders within 75 calendar days after such termination, or (B) such
         termination would not reasonably be expected to interfere with the Loan
         Parties' ability to complete and operate the Project in accordance with
         the covenants contained in the Loan Documents;

                  (t) any Loan Party or Affiliate of any Loan Party shall fail
         to comply with any of its obligations under any Project Document, or
         any Project Document is terminated or shall become void or
         unenforceable, except where the failure to so comply or such
         termination, voidness or unenforceability, individually or in the
         aggregate, would not be reasonably expected to result in a Material
         Adverse Effect;

                  (u) any Governmental Authority in any Project Country or the
         Netherlands shall (i) declare a moratorium on the payment of external
         debt or take other action that impairs the ability of any Loan Party to
         make any payment when due under any Loan Document or to transfer
         Dollars to the United States or (ii) impose any obligation on any Loan
         Party (in respect of a Concession or otherwise) that is reasonably
         likely to result in a Material Adverse Effect;

                  (v) the Project is at any time wholly or substantially
         abandoned or suspended for a period exceeding 30 days, whether or not
         in stages and whether or not by reason of force majeure beyond the
         control of Holdings or any other Person;

<PAGE>

                  (w) any event occurs that would, whether after the passage of
         time or the giving of notice or otherwise, give AT&T the right to
         terminate, revoke or suspend either Brand License Agreement and either
         (i) such event continues unremedied for a period of five consecutive
         Business Days after notice thereof to Holdings and AT&T or (ii) AT&T
         terminates, revokes or suspends either Brand License Agreement or
         exercises other rights or remedies thereunder (other than taking action
         to cause Holdings to comply with the applicable Brand License
         Agreement);

                  (x) the occurrence, since September 30, 2001, of a material
         adverse change in the business, assets, operations, condition
         (financial or otherwise) or prospects of Holdings, the Borrower and the
         Restricted Subsidiaries, taken as a whole;

                  (y) an ERISA Event shall have occurred that, when taken
         together with all other ERISA Events that have occurred, would
         reasonably be expected to result in a Material Adverse Effect; or

                  (z) at any time on or after June 30, 2003, the
         Argentina Payment Condition is not satisfied.

then, and in every such event, and at any time thereafter during the continuance
of such event, the Administrative Agent under each Participating Credit
Agreement may or shall, as the case may be, exercise the remedies set forth in
the applicable Participating Credit Agreement, in addition to any other remedies
permitted under the Loan Documents.

                                  ARTICLE VIII
                                  MISCELLANEOUS

                  SECTION 8.01. NOTICES. All notices and other communications
provided for herein shall be given as provided in Section 11.01 of the
Collateral Agency Agreement.

                  SECTION 8.02. WAIVERS; AMENDMENTS. (a) No failure or delay by
any Agent or any Lender in exercising any right or power hereunder or under any
other Loan Document shall operate as a waiver thereof, nor shall any single or
partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights
and remedies of the Agents and the Lenders hereunder and under the other Loan
Documents are cumulative and are not exclusive of any rights or remedies that
they would otherwise have. No waiver of any provision of this Agreement or
consent to any departure by any Loan Party therefrom shall in any

                                      121
<PAGE>

event be effective unless the same shall be permitted by paragraph (b) of this
Section, and then such waiver or consent shall be effective only in the specific
instance and for the purpose for which given. Without limiting the generality of
the foregoing, the making of a Loan shall not be construed as a waiver of any
Default, regardless of whether an Agent or any Lender may have had notice or
knowledge of such Default at the time.

                  (b) Neither this Agreement nor any provision hereof may be
waived, amended or modified except pursuant to an agreement or agreements in
writing entered into by Holdings, the Borrower and the Required Total Lenders;
PROVIDED that:

                  (i) no such agreement shall adversely affect any rights,
         immunities or rights to indemnification of any Agent (in its capacity
         as such) hereunder without the prior written consent of such Agent;

                  (ii) no such agreement shall, without the prior written
         consent of each Lender (or, in the case of clause (B) below, each
         affected Lender), (A) modify any provision of this Agreement (including
         Section 2.02, Section 2.03 or the definition of "Pro Rata Share") in a
         manner that would alter the manner in which reductions of Commitments
         or prepayments of Loans are required to be allocated and shared
         hereunder, (B) modify or waive any condition set forth in Article IV or
         (C) change the definition of "Required Total Lenders", this Section or
         any other provision of this Agreement specifying the identity, number
         or percentage of Lenders required to waive, amend or modify any rights
         thereunder or make any determination, grant any consent or give any
         instructions hereunder;

                  (iii) unless Non-Vendor Lenders hold outstanding Loans and
         Commitments under the Participating Credit Agreements representing more
         than 50% of the sum of all outstanding Loans and Commitments at the
         time, no such agreement shall, without the prior written consent of
         Lenders having outstanding Loans and Commitments under each Material
         Participating Credit Agreement representing more than 50% of the sum of
         the total outstanding Loans and Commitments under each such Material
         Participating Credit Agreement at the time (in addition to the consent
         of the Required Total Lenders and any other consent required under
         clause (i) or (ii) above), (A) modify or waive any provision of this
         Agreement relating to the requirements applicable to the Brazilian
         Debentures or any Brazilian Debenture Refinancing Indebtedness
         (including the terms of the Supplemental Agreement or the definition of
         the term "Brazilian Debentures" or "Brazilian Debenture Refinancing
         Indebtedness" or any definition used therein (to the extent

                                      122
<PAGE>

         affecting such definition)), (B) modify or waive any provision of this
         Agreement (including any definition) in a manner that would have the
         effect of reducing, postponing or excusing any mandatory prepayment of
         Loans or reduction of Commitments that otherwise would be due
         hereunder, other than a modification or waiver that would reduce any
         such prepayment or reduction by an amount not exceeding 10% of the
         amount that would have been required without giving effect to any
         previous modification or waiver of this Agreement, (C) modify or waive
         any provision of Section 5.20 or Section 5.21 (or any definition used
         in any such provision, to the extent affecting such provision), (D)
         modify or waive any provision of this Agreement (including any
         definition) in a manner that would have the effect of increasing the
         maximum amount (other than with respect to the $50,000,000 limit on
         Permitted Senior Secured Indebtedness committed or arranged by any of
         the Suppliers) of Loans, Other Senior Secured Indebtedness and
         unsecured Indebtedness incurred to finance the construction or
         acquisition of the OSS permitted by clause (a) of Section 6.01 on the
         date of execution of this Agreement, (E) modify or waive any provision
         of Section 6.04 or any definition used therein (to the extent affecting
         such Section), except that (1) the conditions and criteria applicable
         to Permitted Business Acquisitions may be modified or waived, other
         than with respect to any modification or waiver of clause (v) of the
         proviso to the definition of the term "Permitted Business Acquisition",
         which may only be modified or waived to the extent that clause (F)
         below would permit modification or waiver of the corresponding
         covenants referred to in such clause (v) and (2) clause (iii) of
         Section 6.04(b) may be amended or waived to increase the dollar amount
         of asset sales, transfers and other dispositions permitted thereunder
         by up to $40,000,000 in the aggregate (it being understood that any
         modification or waiver relating to the treatment of the Net Proceeds
         from any such sale, transfer or disposition shall be subject to the
         consent requirement of clause (B) above)), (F) modify or waive any
         provision of Section 6.15, 6.16, 6.17, 6.18, 6.19, 6.20, 6.21, 6.22,
         6.23 or 6.24 or any definition used therein (to the extent affecting
         such provision), unless, after giving effect thereto, the provisions of
         each such Section would be at least as restrictive as required by
         Schedule 8.02, or (G) waive any Default relating to any of the
         provisions referred to in clauses (A) through (F) above or under clause
         (c), (o), (p), (s), (u), (v) or (w) of Section 7.01, or modify any such
         clause or any definition used therein (to the extent affecting any such
         clause); and

                  (iv) notwithstanding the foregoing provisions of this Section,
         at any time that there are at least two Non-Vendor Lenders (that are
         not Affiliates of each other) and the

                                      123
<PAGE>

         total amount of outstanding Loans and Commitments under the
         Participating Credit Agreements held by Non-Vendor Lenders exceeds
         $50,000,000, the maximum amount of Loans, Other Senior Secured
         Indebtedness and unsecured Indebtedness incurred to finance the
         construction or acquisition of the OSS permitted by clause (a) of
         Section 6.01 may be amended with the prior written consent of
         Non-Vendor Lenders holding Loans and Commitments under the
         Participating Credit Agreements representing more than 50% of the sum
         of all outstanding Loans and Commitments held by Non-Vendor Lenders at
         the time (without the consent of any Vendor Lenders).

                  SECTION 8.03. EXPENSES; INDEMNITY; DAMAGE WAIVER. (a) Holdings
and the Borrower jointly and severally agree to pay (i) all reasonable,
evidenced out-of-pocket expenses incurred by each of the Initial Lenders, the

disbursements of counsel for each of the Initial Lenders, the Agents and the
Local Financing Bank, in connection with the preparation, execution, delivery
and administration of the Loan Documents or any amendments, modifications or
waivers thereof (whether or not the transactions contemplated hereby are
consummated); PROVIDED that (A) except to the extent otherwise agreed to in
writing by Holdings or the Borrower, for the purposes of this clause (i) only,
such counsel for the Initial Lenders (and the Agents that are Initial Lenders)
shall be limited to one firm of common counsel to the Initial Lenders (and the
Agents that are Initial Lenders) in each of the United States, the Netherlands
and each Project Country and (B) Holdings and the Borrower shall not be required
to pay (1) any arranger, financial advisory or consulting fees and expenses
incurred by the Suppliers, the Lenders, any Agent and any Local Financing Bank,
or their affiliates, or advisors or consultants retained by them and (2) the
costs of any export-import agency financing arrangements obtained by any Lender,
(ii) all out-of-pocket costs and expenses, including lien search and filing
fees, and other taxes and registration fees necessary in order to satisfy the
Collateral and Guarantee Requirement and (iii) all out-of-pocket expenses
incurred by any Agent, any Lender or the Local Financing Bank, including the
reasonable fees, charges and disbursements of any counsel for any Agent, any
Lender or the Local Financing Bank, in connection with the enforcement or
protection of its rights in connection with the Loan Documents, including its
rights under this Section, or in connection with the Loans or Local Financing
Loans, including all such costs and expenses incurred during any workout,
restructuring or similar negotiations in respect of such Loans or Local
Financing Loans.

                  (b) Holdings and the Borrower jointly and severally agree to
indemnify each Agent, each Lender and the Local Financing Bank, and each Related
Party of any of the foregoing Persons (each such Person being called an
"INDEMNITEE") against,

                                      124
<PAGE>

and hold each Indemnitee harmless from, any and all losses, claims, damages,
liabilities and related expenses, including the fees, charges and disbursements
of any counsel for any Indemnitee, incurred by or asserted against any
Indemnitee arising out of, in connection with, or as a result of (i) the
execution or delivery of any Loan Document or any other agreement or instrument
contemplated hereby, the performance by the parties to the Loan Documents of
their respective obligations thereunder or the consummation of the Transactions
or any other transactions contemplated hereby, (ii) any Commitment or Loan or
the use of the proceeds therefrom, (iii) any actual or alleged presence or
release of Hazardous Materials on or from any Mortgaged Property or any other
property at any time owned or operated by any Loan Party or at which any
Collateral is located or any Environmental Liability related in any way to any
Loan Party, or (iv) any actual or prospective claim, litigation, investigation
or proceeding relating to any of the foregoing, whether based on contract, tort
or any other theory and regardless of whether any Indemnitee is a party thereto;
PROVIDED that such indemnity shall not, as to any Indemnitee, be available to
the extent that such losses, claims, damages, liabilities or related expenses
have resulted from the gross negligence or wilful misconduct of such Indemnitee
or any of its Related Parties.

                  (c) To the extent permitted by applicable law, neither the
Borrower nor Holdings shall assert, and each hereby waives, any claim against
any Indemnitee, on any theory of liability, for special, indirect, consequential
or punitive damages (as opposed to direct or actual damages) arising out of, in
connection with, or as a result of, this Agreement, any other Loan Document or
any agreement or instrument contemplated hereby, the Transactions, any Loan or
the use of the proceeds thereof; PROVIDED that the provisions of this paragraph
(c) shall not be construed to apply to any rights that the Borrower or Holdings
may have against any Supplier under its Supply Contract (which shall be governed
by such Supply Contract).

                  (d) All amounts due under this Section shall be payable on
demand.

this Agreement shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and assigns permitted hereby, except that
neither the Borrower nor Holdings may assign or otherwise transfer any of its
rights or obligations hereunder without the prior written consent of each Lender
(and any attempted assignment or transfer by the Borrower or Holdings without
such consent shall be null and void). Nothing in this Agreement, expressed or
implied, shall be construed to confer upon any Person (other than the parties
hereto, their respective successors and assigns permitted hereby and, to the
extent expressly contemplated hereby, the Related

                                      125

Agreement.

                  SECTION 8.05. SURVIVAL. All covenants, agreements,
representations and warranties made by the Loan Parties in the Loan Documents
and in the certificates or other instruments delivered in connection with or
pursuant to this Agreement or any other Loan Document shall be considered to
have been relied upon by the other parties hereto and shall survive the
execution and delivery of the Loan Documents and the making of any Loans,
regardless of any investigation made by any such other party or on its behalf
and notwithstanding that any Agent or any Lender may have had notice or
knowledge of any Default or incorrect representation or warranty at the time any
credit is extended under any Loan Document, and shall continue in full force and
effect as long as the principal of or any accrued interest on any Loan or any
fee or any other amount payable under any Participating Credit Agreement is
outstanding and unpaid and so long as the Commitments have not expired or
terminated. The provisions of Section 8.03 shall survive and remain in full
force and effect regardless of the consummation of the transactions contemplated
hereby, the repayment of the Loans, the expiration or termination of the
Commitments or the termination of this Agreement or any provision hereof.

                  SECTION 8.06. COUNTERPARTS; INTEGRATION; EFFECTIVENESS. This
Agreement may be executed in counterparts (and by different parties hereto on
different counterparts), each of which shall constitute an original, but all of
which when taken together shall constitute a single contract. This Agreement,
the other Loan Documents and any separate letter agreements with respect to the
Borrower's and other Persons' agreement to cooperate with respect to marketing,
selling or syndicating Loans and Commitments or with respect to fees payable to
the Initial Lenders or any Agent constitute the entire contract among the
parties relating to the subject matter hereof and supersede any and all previous
agreements and understandings, oral or written, relating to the subject matter
hereof. This Agreement shall become effective when it shall have been executed
by the Administrative Agents and when the Administrative Agents shall have
received counterparts hereof which, when taken together, bear the signatures of
each of the other parties hereto (other than the Collateral Agent), and
thereafter shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns. It is understood and agreed that
execution and delivery of this Agreement by the

                                      126
<PAGE>

Collateral Agent shall not be required in order for this Agreement to become
effective and binding on the other parties hereto, but shall be a condition to
the Effective Date. Delivery of an executed counterpart of a signature page of
this Agreement by telecopy shall be effective as delivery of a manually executed
counterpart of this Agreement.

                  SECTION 8.07. SEVERABILITY. Any provision of this Agreement
held to be invalid, illegal or unenforceable in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such invalidity, illegality
or unenforceability without affecting the validity, legality and enforceability
of the remaining provisions hereof; and the invalidity of a particular provision
in a particular jurisdiction shall not invalidate such provision in any other
jurisdiction. The parties shall endeavor in good-faith negotiations to replace
the invalid, illegal or unenforceable provisions with valid provisions the
economic effect of which comes as close as possible to that of the invalid,
illegal or unenforceable provisions.

                  SECTION 8.08. RIGHT OF SETOFF. If an Event of Default shall
have occurred and be continuing, each Lender and each of its Affiliates is
hereby authorized at any time and from time to time, to the fullest extent
permitted by law, to set off and apply any and all deposits (general or special,
time or demand, provisional or final) at any time held and other obligations at
any time owing by such Lender or Affiliate to or for the credit or the account
of the Borrower or Holdings against any of and all the obligations of the
Borrower or Holdings now or hereafter existing under the Loan Documents held by
such Lender, irrespective of whether or not such Lender shall have made any
demand under the Loan Documents and although such obligations may be unmatured.
The rights of each Lender under this Section are in addition to other rights and
remedies (including other rights of setoff) which such Lender may have.

                  SECTION 8.09. GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE
OF PROCESS. (a) THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND
GOVERNED BY THE LAW OF THE STATE OF NEW YORK.

                  (b) Each of the parties hereto hereby irrevocably and
unconditionally submits, for itself and its property, to the nonexclusive
jurisdiction of the Supreme Court of the State of New York sitting in New York
County and of the United States District Court of the Southern District of New
York, and any appellate court from any thereof, in any action or proceeding
arising out of or relating to any Loan Document, or for recognition or
enforcement of any judgment, and each of the parties hereto hereby irrevocably
and unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in such New York State or, to the extent
permitted by law, in such Federal court. To the extent permitted

                                      127
<PAGE>

by law, each of the parties hereto agrees that a final judgment in any such
action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
Nothing in this Agreement or any other Loan Document shall affect any right that
any Agent or any Lender may otherwise have to bring any action or proceeding
relating to this Agreement or any other Loan Document against the Borrower or
Holdings or its properties in the courts of any jurisdiction.

                  (c) Each of the parties hereto hereby irrevocably and
unconditionally waives, to the fullest extent it may legally and effectively do
so, any objection which it may now or hereafter have to the laying of venue of
any suit, action or proceeding arising out of or relating to this Agreement or
any other Loan Document in any court referred to in the first sentence of
paragraph (b) of this Section. Each of the parties hereto hereby irrevocably
waives, to the fullest extent permitted by law, the defense of an inconvenient
forum to the maintenance of such action or proceeding in any such court.

                  (d) Each party to this Agreement irrevocably consents to
service of process in the manner provided for notices in Section 8.01. Each of
Holdings and the Borrower hereby irrevocably designates, appoints and empowers
CT Corporation System, with offices on the date hereof at 111 Eighth Avenue,
13th Floor, New York, New York 10011, as its designee, appointee and agent to
receive and accept for and on its behalf, and in respect of its property,
service of any and all legal process, summons, notices and documents which may
be served in any action or proceeding described in paragraph (b) above. If for
any reason such designee, appointee and agent shall cease to act as such, each
of Holdings and the Borrower agrees to designate a new designee, appointee and
agent in New York City on the terms and for the purposes of this provision
reasonably satisfactory to the Administrative Agents. Nothing in this Agreement
or any other Loan Document will affect the right of any party to this Agreement
to serve process in any other manner permitted by law.

                  SECTION 8.10. WAIVERS. (a) WAIVER OF JURY TRIAL. EACH PARTY
HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY
RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR
INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY OTHER LOAN DOCUMENT
OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT,
TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO
REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY
OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK
TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER
PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS

                                      128
<PAGE>

AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN
THIS SECTION.

                  (b) WAIVER OF SOVEREIGN IMMUNITY. TO THE EXTENT THAT ANY LOAN
PARTY HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION OF ANY COURT
OR FROM ANY LEGAL PROCESS, SUCH LOAN PARTY HEREBY WAIVES SUCH IMMUNITY AND
AGREES NOT TO ASSERT, BY WAY OF MOTION, AS A DEFENSE, OR OTHERWISE, IN ANY SUCH
SUIT, ACTION OR PROCEEDING, ANY CLAIM THAT IT IS NOT PERSONALLY SUBJECT TO THE
JURISDICTION OF THE COURTS NAMED IN SECTION 8.09(b), THAT IT IS IMMUNE FROM ANY
LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE, ATTACHMENT PRIOR TO JUDGMENT,
ATTACHMENT IN AID OF EXECUTION, EXECUTION OR OTHERWISE) WITH RESPECT TO ITSELF
OR ITS PROPERTY, OR ATTACHMENT EITHER PRIOR TO JUDGMENT OR IN AID OF EXECUTION,
BY REASON OF SOVEREIGN IMMUNITY, OR OTHERWISE, THAT THE VENUE OF THE SUIT,
ACTION OR PROCEEDING IS IMPROPER OR THAT THIS AGREEMENT OR ANY OTHER LOAN
DOCUMENT OR THE SUBJECT MATTER HEREOF OR THEREOF MAY NOT BE ENFORCED IN OR BY
SUCH COURTS.

                  SECTION 8.11. HEADINGS. Article and Section headings and the
Table of Contents used herein are for convenience of reference only, are not
part of this Agreement and shall not affect the construction of, or be taken
into consideration in interpreting, this Agreement.

                  SECTION 8.12. CONFIDENTIALITY. Each of the Agents and the
Lenders agrees to maintain the confidentiality of the Information (as defined
below), except that Information may be disclosed (a) to its and its Affiliates'
directors, officers, employees and agents, including accountants, legal counsel
and other advisors (it being understood that the Persons to whom such disclosure
is made will be informed of the confidential nature of such Information and
instructed to keep such Information confidential), (b) to the extent requested
by any regulatory authority, (c) to the extent required by applicable laws or
regulations or by any subpoena or similar legal process, (d) to any other party
to this Agreement or any Participating Credit Agreement, (e) in connection with
the exercise of any remedies hereunder or any suit, action or proceeding
relating to this Agreement or any other Loan Document or the enforcement of
rights hereunder or thereunder, (f) subject to a written agreement containing
provisions substantially the same as those of this Section, to any assignee of
or Participant (as defined in a Participating Credit Agreement) in, or any
prospective assignee of or Participant in, any of its rights or obligations
under the Loan Documents, (g) with the consent of any Loan Party or (h) to the
extent such Information (i) becomes publicly available other than as a result of
a breach of this Section or (ii) becomes available to any Agent or any Lender on
a nonconfidential basis from a source other than any Loan Party. For the
purposes of this Section, "INFORMATION" means all information received from any
Loan Party relating to any Loan Party or the Project, other

                                      129
<PAGE>

than any such information that is publicly available or available to any Agent
or any Lender on a nonconfidential basis prior to disclosure by any Loan Party.
Any Person required to maintain the confidentiality of Information as provided
in this Section shall be considered to have complied with its obligation to do
so if such Person has exercised the same degree of care to maintain the
confidentiality of such Information as such Person would accord to its own
confidential information.

                  SECTION 8.13. DESIGNATION OF UNRESTRICTED SUBSIDIARIES. The
Board of Directors of Holdings may designate any Subsidiary that is not a Loan
Party (including any newly acquired or newly formed Subsidiary) to be an
Unrestricted Subsidiary if (a) such Subsidiary does not own any Equity Interests
of, and does not own or hold any Lien on any property of, any Loan Party, (b)
such Subsidiary does not own or lease any Network Infrastructure, (c) such
Subsidiary is not party to any material agreement, contract, arrangement or
understanding with Holdings or any Restricted Subsidiary unless the terms of any
such agreement, contract, arrangement or understanding are no less favorable to
Holdings or such Restricted Subsidiary than those that might be obtained at the
time in an arm's-length transaction with Persons who are not Affiliates of
Holdings, (d) neither Holdings nor any Restricted Subsidiary has any direct or
indirect obligation to subscribe for additional Equity Interests in such
Subsidiary or to maintain or preserve such Subsidiary's financial condition or
to cause such Subsidiary to achieve any specified levels of operating results,
(e) such Subsidiary has at least one director on its board of directors that is
not a director or executive officer of Holdings or any Restricted Subsidiary and
at least one executive officer that is not a director or executive officer of
Holdings or any Restricted Subsidiary, (f) such Subsidiary does not hold any
Concession or other Governmental Approval relating to the Project, (g) no Loan
Party has Guaranteed any Indebtedness of such Subsidiary outstanding at the time
of such designation, (h) such Subsidiary does not have any Indebtedness
outstanding if the occurrence of a default thereunder, after the giving of
notice, lapse of time or otherwise, or the exercise of remedies with respect
thereto would result in a default under any Indebtedness of any Loan Party or
otherwise permit, after the giving of notice, lapse of time or otherwise, any
holder of any Indebtedness of any Loan Party to accelerate the maturity of such
Indebtedness and (i) after giving effect to such designation Holdings, the
Borrower and the Restricted Subsidiaries will be in compliance with the
provisions of Section 6.04. For the purposes of determining compliance with
clause (i) of the previous sentence, all investments made by Holdings or any
Restricted Subsidiary in a Subsidiary on or prior to the date that such
Subsidiary is designated an Unrestricted Subsidiary shall be deemed to be made
on the date of such designation. The Board of Directors of Holdings may
designate any Unrestricted Subsidiary to be a Restricted Subsidiary;

                                      130
<PAGE>

PROVIDED that (a) Holdings is in compliance on a pro forma basis after giving
effect to such designation, with the covenants contained in Sections 6.15
through 6.24 recomputed as at the last day of the most recently ended fiscal
quarter of Holdings for which financial statements are available, as if such
designation had occurred on the first day of each relevant period for testing
such compliance and (b) immediately after giving effect to such designation, no
Default shall have occurred and be continuing. Any designation permitted under
this Section shall be evidenced to the Agents by delivering to each of them a
certified copy of the resolution of the Board of Directors of Holdings giving
effect to such designation and a certificate of a Financial Officer certifying
that such designation complies with the foregoing conditions.

                  SECTION 8.14. INTEREST RATE LIMITATION. Notwithstanding
anything herein to the contrary, if at any time the interest rate applicable to
any Loan, together with all fees, charges and other amounts that are treated as
interest on such Loan under applicable law (collectively the "CHARGES"), shall
exceed the maximum lawful rate (the "MAXIMUM RATE") that may be contracted for,
charged, taken, received or reserved by the Lender holding such Loan in
accordance with applicable law, the rate of interest payable in respect of such
Loan hereunder, together with all Charges payable in respect thereof, shall be
limited to the Maximum Rate and, to the extent lawful, the interest and Charges
that would have been payable in respect of such Loan but were not payable as a
result of the operation of this Section shall be cumulated and the interest and
Charges payable to such Lender in respect of other Loans or periods shall be
increased (but not above the Maximum Rate therefor) until such cumulated amount,
together with interest thereon at the Federal Funds Effective Rate to the date
of repayment, shall have been received by such Lender.

                  SECTION 8.15. JUDGMENT CURRENCY. (a) The obligations of
Holdings and the Borrower hereunder and each Loan Parties' obligations under the
other Loan Documents to make payments in Dollars (the "OBLIGATION CURRENCY")
shall not be discharged or satisfied by any tender or recovery pursuant to any
judgment expressed in or converted into any currency other than the Obligation
Currency, except to the extent that such tender or recovery results in the
effective receipt by the applicable Agent or Lender of the full amount of the
Obligation Currency expressed to be payable to such Agent or Lender under this
Agreement or the other Loan Documents. If, for the purpose of obtaining or
enforcing judgment against the Borrower or any other Loan Party in any court or
in any jurisdiction, it becomes necessary to convert into or from any currency
other than the Obligation Currency (such other currency being hereinafter
referred to as the "JUDGMENT CURRENCY") an amount due in the Obligation
Currency, the conversion shall be made, at the rate of exchange

                                      131
<PAGE>

(as quoted by the applicable Administrative Agent or, if such Administrative
Agent does not quote a rate of exchange on such currency, by a known dealer in
such currency designated by such Administrative Agent) determined, in each case,
as of the date immediately preceding the day on which the judgment is given
(such Business Day being hereinafter referred to as the "JUDGMENT CURRENCY
CONVERSION DATE").

                  (b) If there is a change in the rate of exchange prevailing
between the Judgment Currency Conversion Date and the date of actual payment of
the amount due, the Borrower covenants and agrees to pay, or cause to be paid,
such additional amounts, if any (but in any event not a lesser amount), as may
be necessary to ensure that the amount paid in the Judgment Currency, when
converted at the rate of exchange prevailing on the date of payment, will
produce the amount of the Obligation Currency that could have been purchased
with the amount of Judgment Currency stipulated in the Judgment or judicial
award at the rate of exchange prevailing on the Judgment Currency Conversion
Date.

                  (c) For purposes of determining the rate of exchange for this
Section, such amounts shall include any premium and costs payable in connection
with the purchase of the Obligation Currency.

                  SECTION 8.16. CHILEAN REORGANIZATION. Each of the Initial
Lenders under the Initial Participating Credit Agreements has acknowledged that
Holdings may cause a reorganization (the "CHILEAN REORGANIZATION") of AT&T Chile
Holding S.A. pursuant to which AT&T Chile Holding S.A. will be converted from a
corporation to a limited liability partnership. In the event that the Chilean
Reorganization requires amendments to the Loan Documents, the Initial Lenders to
the Initial Participating Credit Agreements will negotiate in good faith with
Holdings in respect of such amendments, subject to their satisfaction that the
Chilean Reorganization will not impair their collateral position in any material
respect. Holdings has acknowledged that in order to ensure that the Chilean
Reorganization does not impair the collateral position of the Lenders, it may be
necessary to covenant that the entity that results from the Chilean
Reorganization will remain a holding company with no assets or business other
than owning the shares of its subsidiaries, all of which shares shall be pledged
under the Security Documents.

                  SECTION 8.17. ACKNOWLEDGMENT. The parties acknowledge that the
following events (the "DESIGNATED EVENTS") relating to Argentina have occurred
during the period between the Closing Date and the Effective Date: (a) the
decision, announced December 24, 2001, of President Adolfo Rodriguez Saa to
suspend payments of Argentine external debt, (b) the abrogation of

                                      132
<PAGE>

Convertibility Law No. 23,928 pursuant to Law No. 25,561 dated January 6, 2002,
(c) the suspension of foreclosure proceedings for 180 days as provided by Law
No. 25,563 dated February 14, 2002, (d) the creation of a single foreign
exchange market as provided by Argentine Executive Power of Decree 260/2002
dated February 8, 2002, (e) the requirement that until May 1, 2002 certain
transfers of Dollars outside Argentina for purposes of making principal payments
under financial obligations be approved in advance by the Central Bank of
Argentina as provided by Communication "A" 3471 by the Central Bank dated
February 8, 2002, (f) the conversion of payment obligations of customers of the
Argentine Operating Subsidiary from Dollars into Argentine Pesos as provided by
Argentine Executive Power of Decree 214/2002 dated February 3, 2002, (g) the
requirement that, from March 25, 2002 onwards, transfers of Dollars outside
Argentina for the purposes of making principal and interest payments under
financial obligations be approved in advance by the Central Bank of Argentina,
as provided by Communication "A" 3537 by the Central Bank of Argentina dated
March 25,2002; PROVIDED that any action taken after the Effective Date pursuant
to any decisions, moratoriums, laws, decrees, rules or regulations listed in the
foregoing clauses (a) through (f) that is not expressly referred to herein shall
not constitute a Designated Event. The parties acknowledge and agree that,
subject to the following paragraph, the Designated Events shall not be deemed to
(a) constitute a default under clause (m), (n), (u) or (x) of Section 7.01, (b)
render untrue or incorrect any of the representations and warranties made
pursuant to Article III or (c) constitute a Material Adverse Effect.

                  Notwithstanding the foregoing, if, after March 25, 2002,
events, circumstances or changes in Argentina occur (whether resulting from the
Designated Events or not, and whether individually or together with one or more
Designated Events or other events, circumstances or changes) which cause a
further deterioration or escalation in the economic or political situation in
Argentina, nothing in this Section shall be construed as a waiver of any rights
or powers of the Agents or the Lenders under this Agreement or under any other
Loan Document, or be construed as an acknowledgment that a Default does not
result from such deterioration or escalation, or that a representation and
warranty is not rendered untrue or incorrect as a result of such deterioration
or escalation, or that a Material Adverse Effect does not result from such
deterioration or escalation.

                  SECTION 8.18. AMENDMENT AND RESTATEMENT. This Agreement was
initially executed by the parties hereto (other than the Collateral Agent) as of
December 21, 2001, and has been amended and restated in the form hereof as of
March 25, 2002. All references in this Agreement to "the date hereof" shall,
unless the context clearly requires otherwise, be deemed to be references to the
Closing Date.

                  IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be duly executed by their respective authorized officers as of the
day and year first above written.
