                                    consisting of the improvements to the real

         5.       PREMISES:

         A. The Premises is located on the second floor of the Building and is
shown on Exhibit B-1 attached to the Lease. In addition to Tenant's right to use
and occupy the Premises, Tenant shall be entitled to use and occupy, for the
placement of its Ancillary Equipment, the Tenant's Equipment Area. For purpose
of this Rider and the Lease, the term "Ancillary Equipment" includes, but is not
limited to, Tenant's back- up generator and related fuel storage tanks,
antennas, dry coolers and related heating, ventilation and air conditioning
("HVAC") systems and equipment, fiber optic cable, conduits, horizontal and
vertical shafts; electrical and power vaults, power lines from the main entry
point into the Building, power lines from Tenant's back-up generator, and
related systems and equipment. For the purpose of this Rider and the Lease, the
term "Tenant's Equipment Area" means the risers, equipment pods, platforms
and/or structurally supported roof areas identified and allocated for Tenant on
Exhibit B-2 attached to the Lease.

         B. Tenant shall have access to the Premises and to Tenant's Equipment
Area twenty-four (24) hours per day, seven (7) days per week. Tenant shall
obtain, in advance and at its own cost, all permits and approvals required from
any municipal or governmental authority necessary for it to use and occupy
Tenant's Equipment Area for Tenant's intended purposes and to install Tenant's
Ancillary Equipment. Landlord's prior written approval, not to be unreasonably
withheld, shall be obtained with respect to the specific equipment Tenant
desires to place in Tenant's Equipment Area. Tenant acknowledges that Landlord
may have reserved certain risers, pads, roof locations, and similar areas of the
Building for lease to tenants who have in excess of building standard need for
such areas.

         6. RENTABLE AREA: The Rentable Area of the Premises is 149,184 square
feet on the second floor of the Building. The Rentable Area consists of (i) the
rentable square footage of the Premises for either full floor or partial floor
tenants (as appropriate), increased by (ii) a common equipment core factor (the
"Equipment Core Factor") of 1.24. The Equipment Core Factor has been computed by
Landlord's architect and takes into account the areas of the Building (of which
Tenant's Equipment Area is a pad) made available to tenants of the Building for
the location of their Ancillary Equipment. At Landlord's or Tenant's request,
the floor area of the Premises shall be remeasured by Landlord's architect after
possession of the Premises is delivered to Tenant (but before the Rent
Commencement Date), and to the extent the floor area ]S revised as a result of
such remeasurement, the rentals and other charges set forth herein shall be
equitably and proportionately adjusted (and the parties shall execute a written
lease amendment to confirm the changes, if any).

<PAGE>

         7. PROPORTIONATE SHARE: Tenant's Proportionate Share is a fraction,
stated in decimal terms, the numerator of which is the Rentable Area of the
Premises and the denominator of which is 745,922. Tenant's Proportionate Share
is agreed to be twenty percent (20.00%) (unless Tenant occupies additional
space, in which event Tenant's Proportionate Share shall be recomputed, by using
the increased Rentable Area as the numerator and 745,922 as the denominator).

         8. LEASE COMMENCEMENT DATE AND DELIVERY DATE: It is understood and
agreed that, notwithstanding the fact that the Lease Commencement Date and the
Delivery Date shall be the same date, which shall be the date of substantial
completion of Landlord's Work as described in Exhibit C to the Lease, this Lease
shall be effective on the Effective Date. It is understood and agreed that in
the event that Tenant is authorized to have access to the Premises prior to the
Delivery Date all of the terms and conditions of this Lease, except for the
obligation to pay Base Rent and, if applicable, Additional Rent, shall commence
in accordance with paragraph 9 below, the terms and conditions of this Lease
shall then be in effect.

         9. RENT COMMENCEMENT DATE: The Rent Commencement Date is ninety (90)
days following the Delivery Date. The Rent Commencement Date is the date on
which the Base Rent and the Additional Rent shall commence being paid by Tenant.

         10. EXPIRATION DATE: The last day of the month which is twenty (20)
years after the Rent Commencement Date, subject to the terms contained in
Section.

         11. LEASE TERM: From the Lease Commencement Date to the Expiration
Date, unless extended or sooner terminated in accordance with the Lease.

         12. RENEWAL OPTIONS:

         A. Landlord grants to Tenant two (2) options to extend the Lease Term
for an additional period of five (5) years each ("Renewal Term"), under the
terms and conditions hereinafter set forth. Tenant may only validly exercise the
aforesaid options to extend if: (a) the Lease is in fill force and effect at the
time of the exercise of said option, and the Tenant is not in default of the
Lease at such time and at the time that the extension of the Term would take
effect; (b) Tenant shall be in possession of the entire Premises, except to the
extent that a different party is properly in possession of all or any part of
the Premises pursuant to the terms of the Lease, and (c) Tenant shall have
exercised the option to extend by delivering a notice (the "Notice") in writing
to the Landlord not later than twelve (12) months prior to the expiration of the
then-current Lease Term. Failure to exercise the first option shall result in
the automatic termination of the second option.

         B. The Base Rent for each Renewal Term shall be the then-effective
"Market Rent" as determined in accordance with this section, but in no event
shall such Market Rent be less than the Base Rent in effect at the conclusion of
the prior Term. "Market Rent", including escalations for successive years, shall
be determined by Landlord in its reasonable judgment. Landlord's determination
shall be based upon then-current and projected rents in the Building, adjusted
for any special conditions applicable to such space and lease;, for location,
length of term, amounts of space and other factors that Landlord deems relevant
in computing rents for space in the Building, including adjustments for
anticipated inflation. Landlord shall determine the Base Rent for the first year
of any Renewal Term on a price per square foot basis ("Renewal Term Rental
Rate"). The Renewal Term Rental Rate shall then be multiplied by the Rentable
Area. Thereafter, the first year Base Rent for the Renewal Term will be annually
adjusted (on the anniversary date of the beginning of the Renewal Term) by three
percent (3.0%) compounded annually. Landlord shall provide Tenant in writing
with its determination of the then-effective Market Rent within thirty (30) days
after receipt of the Notice. Landlord and Tenant shall negotiate in good faith
to agree upon such Market Rent; provided, however, that if Tenant is not
satisfied with Landlord's determination of Market Rent, Tenant may, prior to the
day nine (9) months before the Expiration Date for the then current Lease Term
either (i) withdraw the Notice, or (ii) submit the determination of Market Rent
to Binding Arbitration pursuant to the provisions of paragraph 12C of this
Rider. The election of (i) or (ii) shall be in writing.

         C. If Tenant elects Binding Arbitration to determine the Market Rent,
then with such election Tenant shall identify an independent real estate

                                       2

appraiser licensed in Miami, Dade County, Florida, with at least ten (10) years
experience in telecommunications leasing and appraising in the central downtown
business district. Landlord shall, within fifteen (15) days, select a similarly
experienced appraiser, and the TWO promptly shall select a third appraiser with
similar qualifications. The appraisers shall be instructed to determine within
thirty (30) days the Market Rent for the Premises as of the beginning of the
Renewal Term in question, assuming (1) the Premises are delivered to a tenant in
their "as-is" condition, but with all of Tenant's equipment removed (it being
agreed that for this purpose Tenant's equipment shall not include light
fixtures, HVAC systems and equipment and fire suppression system and equipment,
which shall be deemed to remain in the Premises). The average of the two brokers
who are closest together in rental rate shall be deemed to be the Market Rent.
The Market Rent so established shall be subject to Three percent (3.0%) annual
increases, and in no event shall it be less than the Base Rent then in effect
for the Premises increased by three percent (2.0%). All other economic and other
terms of this Rider (including, by way of example only, the Additional Rent
provisions) and of the Lease shall remain in fill force and effect Ewing any
Renewal Term. Landlord and Tenant independently shall pay the appraiser they
select and shall share equally the cost of the third appraiser.

         13. BASE RENT: Beginning on the Rent Commencement Dale (it being
understood that the table shown below reflects Base Rent for twenty (20) years
from the Rent Commencement Date and which Base Rent begins at $16.00 per
Rentable Square Foot and escalates at the rate of 3% compounded annually through
the Term, and additionally increased by $1.50 per Rentable Square Foot after the
fifth, tenth and fifteen years of the Term), Tenant shall pay the Base Rent
described below, p]us applicable sales taxes and applicable local taxes

         during such year. If such statement indicates that the aggregate amount
         of such estimated payments exceeds Tenant s actual liability, then
         Tenant shall deduct the net overpayment from its next monthly
         payment(s) of estimated Operating Charges and Real Estate Taxes. If
         such statement indicates that Tenant's actual liability exceeds the
         aggregate amount of such estimated payments, then Tenant shall pay the
         amount of such excess within thirty (30) days of Tenant's receipt of
         such notice of excess due. Such statement of Operating Charges and Real

conduct an audit. The results of any such audit shall be completed not later
than one hundred twenty days (120) days after Tenant's receipt of Landlord's
statement. If as to any specific issue it is determined that Tenant has been
overcharged, then Tenant shall receive a credit against the next month's
required payment of Operating Charges in the amount of such overcharge. If the
audit reveals that Tenant was undercharged, then, within thirty (30) days after
:he results of such audit are made available to Tenant, Tenant shall reimburse
Landlord for the amount of such undercharge. Tenant shall pay the cost of any
audits requested by Tenant, unless any audit reveals that Landlord's
determination of the Operating Charges and/or Real Estate Taxes was in error by
more than five percent (5%), in which case Landlord shall pay the cost of such
audit. Landlord shall be required to maintain records of the Operating Charges
and Real Estate Taxes for the three-year period following each Operating Charges
statement. To the extent either party owes any amount to the other, and such
obligation arises at the end of the Term, such amount shall be paid in its
entirety within thirty (30) days following the completion of the audit process.

                  (c) If the Lease Term commences or expires on a day other than
         the first day or the last day of a calendar year, respectively, then
         Tenant's liability for Tenant's Proportionate Share of Operating
         Charges and Real Estate Taxes incurred during; such calendar year shall
         be equitably apportioned on a pro-rata basis.

         orders of all applicable governmental or quasi-governmental authorities

         substitute certificate of occupancy necessitated by Tenant's particular
         use of the Premises or any Alterations made by Tenant in the Premises
         shall be obtained by Tenant at Tenant's sole expense. (The foregoing
         sentence shall not be construed as to constitute the consent of the
         Landlord for any Alterations of the Premises.) Use of the Premises is

         Landlord shall have the right at any time to relocate such meet point
         room at Landlord's expense, in which event Landlord shall reimburse
         Tenant for Tenant's reasonable expenses incurred in connection with
         relocating its equipment to the relocated meet point room. Prior to the
         discontinuance of any existing meet point room in the Building in
         connection with such a relocation, Landlord shall have constructed a
         new meet point room and Tenant shall have had a reasonable opportunity

         prior to such discontinuance, Tenant shall have had reasonable notice
         and opportunity to connect directly to other tenants of the Building to
         which it is providing its telecommunications services and to other
         telecommunications carriers, in which event Landlord shall reimburse
         Tenant for Tenant's reasonable expenses incurred in connection with
         such direct connections. Further, such "meet me" room shall have direct
         access to the interconnect! fiber termination point within the Tenant's
         Premises at the public or private peering point, and such connection
         shall be at no charge to Landlord throughout the Term, including any

Landlord or so that Landlord is responsible for collection or payment thereof,
then Tenant shall pay to Landlord as Additional Rent the amount of such tax or
fee within thirty (30) days of its having been assessed, but in no event in a
fashion as to constitute a delinquency in the payment of such taxes, fees or
assessments. Tenant shall also promptly pay any sales tax and/or other local tax

                            ASSIGNMENT AND SUBLETTING

         7.1 Except as provided below, Tenant will not sell, assign, transfer,
mortgage or otherwise encumber this Lease or sublet, rent or permit occupancy or
use of the Premises or any part thereof by others, without obtaining the prior
written consent of Landlord, nor shall any assignment or transfer of this Lease
or the right of occupancy hereunder be effectuated by operation of law or
otherwise without the prior written consent of Landlord, which consent may be
granted, withheld or conditioned in the sole and absolute discretion of the
Landlord. Any such assignment, subletting or occupancy without the prior written
consent of Landlord shall constitute an Event of Default, or, at the election of
the Landlord, shall be void. Tenant shall pay all reasonable expenses (including
attorney's fees) incurred by Landlord in connection with Tenant's request for
Landlord to give its consent to any assignment, subletting or occupancy.

         7.2 Provided, that Tenant shall not be in default of this Lease, and
that Tenant shall not have engaged in acts or omissions which with the lapse of
time would constitute a default of this Lease, any transfer, by operation of law
or otherwise, of Tenant's interest in this Lease (in whole or in pad), or of a
fifty percent (50%) or greater interest in Tenant (whether stock, partnership
interest or otherwise), or any mortgaging or encumbering of any interest in
Tenant, shall be deemed an assignment of this Lease within the meaning of this
Article 7. The issuance of shares of stock to other than the existing
shareholders is deemed to be a transfer of that stock for the purposes of this
Article 7. If there has been a previous transfer of less than a fifty percent
(50%) interest in Tenant, then any other transfer of an interest in Tenant
which, when added to the total percentage interest previously transferred,
totals a transfer of greater than a fifty percent (50%) interest in Tenant shall
be deemed an assignment of Tenant's interest in this Lease within the meaning of
this Article 7. Tenant shall be obligated to notify Landlord when a transfer of
fifty percent (50%) or greater interest in Tenant is proposed. The provisions of
this Section 7.2 shall not apply to the sale of shares by persons other than
those deemed "insiders" within the meaning of the Securities Exchange Act of
1934, as amended, where such sale is effected through any recognized exchange or
through the "over-the-counter market."

         7.3 If Landlord shall validly decline to give its consent to any
proposed assignment or sublease, or if Landlord shall exercise any of its rights
under this Article 7, Tenant shall indemnify, defend and hold harmless Landlord
against and from any and all loss, liability, damages, costs and expenses
(including reasonable attorneys' fees) resulting in connection with any claim
relating to the proposed assignment or sublease that may I e made against
Landlord by the proposed assignee or sublessee or by any brokers or other
persons, including, without limitation, claims for a commission or similar
compensation in connection with the proposed assignment or sublease.

         7.4 In the event that (i) Landlord fails to exercise any of its options
under this Article 7 and (ii) Tenant fails to execute and deliver the assignment
or sublease to which Landlord consented within forty-five (45) days after the
giving of such consent then, Tenant shall again comply with all of the
provisions and conditions of this Article 7 before assigning its interest in
this Lease or subletting any portion of the Premises.

         7.5 The consent by Landlord to an assignment or to a subletting shall
not relieve Tenant from obtaining the express consent in writing of Landlord b
any further assignment or subletting. If Tenant's interest in this Lease is
assigned, or if the Premises or any pad thereof is sublet or occupied by anyone
other than Tenant, Landlord may collect rent from the assignee, subtenant or
occupant and apply the net amount collected to the Rent payable hereunder, but
no such assignment, subletting, occupancy or collection shall be deemed a waiver
of the provisions of this Article 7 or of any default hereunder or the
acceptance of the assignee, subtenant or occupant as Tenant, or a release of
Tenant from the further observance or performance by Tenant of all covenants,
conditions, terms and provisions on the part of Tenant to be performed or
observed.

         7.6 Notwithstanding anything to the contrary in this section, Tenant,
without Landlord's consent may, (a) assign this Lease to any party into which
Tenant is merged, consolidated or reorganized, or to which all or substantially
all of Tenant's assets are transferred or sold, provided: (x) Landlord shall
receive a copy of the executed transfer document promptly after execution, (y)
Tenant or its successors by merger shall remain liable under this Lease, and (z)
the transferee shall expressly assume Tenant's obligations under this Lease; and
(b) upon prior written notice to Landlord, sublease the Premises to Tenant's
affiliates. For purposes of this Lease, an affiliate of Tenant is a corporation,

                                       6
<PAGE>

partnership, limited liability company, or other entity that, directly or
indirectly, through one or more intermediaries, controls, is controlled by, or
is under common control with, the Tenant. The term "control" (including the
terms "controlled by" and "under common control with") means the possession,
direct or indirect, of the power to direct, or cause the direction of, the
management and policies of Tenant, whether through the ownership of voting
securities, by contract, or otherwise. Tenant shall give Landlord written notice
(containing the information described above) of and such sublease to Tenant's
affiliates.

         7.7 In the event of an attempted subletting or assignment 10 an
unaffiliated third party, Tenant shall submit a request for consent thereto to
Landlord. If Landlord, in its reasonable discretion elects to deny the request
for consent to assignment, Landlord shall have the right to recapture the
Premises, or that portion of the Premises sought to be subleased, by providing
Tenant written notice of intent to recapture, within thirty (30) days of
Landlord's receipt of a request by Tenant for consent to assignment to an
unaffiliated third party of this permitted assignment If Landlord consents to
such an assignment or sublease, Tenant agrees that Landlord and Tenant shall
equally share in any amount of rent received in excess of the then-effective
Base Rent, after deduction of Landlord's expenses in connection with the
assignment or sublease.

         7.8 A permitted co-location under this Lease shall not constitute an
assignment or sublease within the meaning of this paragraph. Among other things
otherwise described in this Lease, for there to be a permitted co-location, at
all times during the Term, Tenant shall provide Landlord with its then-currently
effective Co-location License Agreement for its Customers for Landlord's review
and approval, which shall not be unreasonably withheld or delayed. Said license
will not afford licensee any interest in the tenancy granted hereby and will
preclude occupancy beyond the Term hereof the mere denomination of a license as
a "sublease" shall not defeat the terms hereof; provided, that the substance of
the relationship established thereby is that of a licensee and not a subtenant.

                                    ARTICLE 8
                             MAINTENANCE AND REPAIRS

         8.1 Tenant shall keep and maintain the Premises and Tenant's Equipment
Area, and all fixtures and equipment located therein, in clean, safe and
sanitary condition, shall take good care thereof and make all repairs thereto,
and shall suffer no waste or injury thereto. At the expiration or earlier
termination of the Lease Term, Tenant shall surrender the Premises, and Tenant's
Equipment Area, in the same order and condition in which they were on the Lease
Commencement Date, ordinary wear and tear and unavoidable damage by the elements
excepted. Except as otherwise provided in Article 18, all injury, breakage and
damage to the Premises and to any other part of the Building or the Land caused
by any act or omission of Tenant or of any invitee, agent, employee, subtenant,
assignee, contractor, client, family member, licensee, customer or guest of
Tenant (collectively, "Invitees"), including any act or omission in connection
with the installation and/or removal of any of Tenant's furniture, fixtures and
equipment, shall be repaired by and at Tenant's expense, except that Landlord
shall have the right at Landlord's option to make any such repair and to charge
Tenant for all costs and expenses incurred in connection therewith.

         8.2 Landlord shall keep and maintain in good order and repair the
base-building structure and systems, including the root exterior walls,
elevators, electrical, plumbing and common area HVAC systems (which excludes
such elevator, electrical, plumbing and HVAC systems to the extent same are
located within or exclusively service the Tenant's Premises or the premises of
other tenants only, in which event same shall be governed by Section 8.1 above),
and the ground floor lobby and other common areas and facilities of the
Building.

                                    ARTICLE 9
                   INITIAL TENANT IMPROVEMENTS AND ALTERATIONS

         9.1 The original improvement of the Premises, and Tenant's Equipment
Area by Tenant shall be accomplished in accordance with EXHIBIT D. Landlord is
under no obligation to make, or to permit Tenant or Tenant's contractors to
make, any structural or other alterations, decorations, additions, improvements

                                       7
<PAGE>

or other changes (collectively "Alterations") in or to the Premises and Tenant's
Equipment Area except as set forth in Exhibit D or otherwise expressly provided
in this Lease. Prior to the commencement by Tenant of the construction of any
original improvements, Tenant shall obtain and deliver to Landlord written,
unconditional waivers of mechanics' and materialmen's liens against the Complex
from all proposed contractors, subcontractors, laborers and suppliers in
connection with such original improvements, in form and content reasonably
satisfactory to Landlord.

         9.2 Tenant shall not make or permit anyone for whom Tenant is
responsible to make any Alterations in or to the Premises, Tenant's Equipment
Area or the Building, without Landlord's prior written consent. The criteria for
such consent shall be determined by the nature of the Alteration and whether
same shall have an impact upon the structural integrity of the Building or a
Building system of general use, or shall have an impact on a tenant other than
the Tenant, in which event, the consent or approval of the Landlord may be
granted, conditioned or withheld in the sole and absolute discretion of the
Landlord. If the two impacts described in the preceding sentence are NOT
factors, in the reasonable judgment of Landlord, then the consent or approval of
the Landlord to an Alteration shall not be unreasonably withheld, conditioned or
delayed. My authorized and approved Alteration made by Tenant shall be made: (a)
in a good, workmanlike, first-class and prompt manner; (b) using new materials
only; (c) by an experienced, reputable contractor, approved in advance by the
Landlord in its reasonable discretion or expressly identified on the Rider, and
constructed in accordance with plans and specifications approved in writing by
Landlord; (d) in accordance with all applicable legal requirements and
requirements of any insurance company insuring the Building or portion thereof,
(e) after having obtained any required consent of the holder of any Mortgage (as
defined in Section 22.1); (f) after Tenant has obtained public liability and
worker's compensation insurance policies approved in writing by Landlord; and
(g) after Tenant has obtained and delivered to Landlord written, unconditional
waivers of mechanics' and materialmen's liens against the Premises and the
Building from all proposed contractors, subcontractors, laborers and material
suppliers for all work and materials in connection with such Alteration. Any
such Alteration shall be performed in a manner consistent with the Building
Rules and Regulations as same may be promulgated from time-to-time by the
Landlord.

         9.3 In the event of an approved Alteration after the initial build-out
of Tenant's Premises, Tenant agrees that Tenant shall reimburse Landlord for its
actual costs of plan review, construction monitoring and oversight by Landlord.
Said reimbursement shall be due within thirty (30) days of Tenant's receipt of
Landlord's statement therefore, and shall be considered Additional Rent.

         9.4 If, notwithstanding the foregoing, any mechanic's or materialman's
lien (or a petition to establish such lien) is filed in connection with any
Alteration, then such lien (or petition) shall be discharged by Tenant at
Tenant's expense within twenty (20) days thereafter by the payment thereof or
the filing of a bond in a form acceptable to Landlord. If Tenant shall fail to
discharge any such mechanic's or materialman's lien, Landlord may, at its
option, discharge such lien and treat the cost thereof (including attorneys'
fees incurred in connection therewith) as additional rent payable with the next
monthly installment of Base Rent falling due; it being expressly agreed that
such discharge by Landlord shall not be deemed to waive or release the default
of Tenant in not discharging such lien. If Landlord gives its consent to the
making of any Alteration, then such consent shall not be deemed to constitute
Landlord's consent to subject its interest in the Premises, the Building or the
Land to any mechanic's or materialman's lien which may be filed in connection
therewith.

         9.5 Consent to an Alteration shall not constitute consent or
authorization by the Landlord to the placement of financing by the Tenant
relating to the Alterations that purports to create any security interest in the
Building or that purports to subordinate this Lease to any such financing, and
any such effort or agreement by Tenant shall constitute an Event of Default.

         9.6 Tenant acknowledges and agrees that, during the construction of
initial improvements, any subsequent Alterations and thereafter dining the
operation of the Building, Landlord has authority to coordinate access to
loading areas, freight elevators, the roof, shafts, space and other areas of the
Building, and that Landlord has authority to adopt reasonable rules and
regulations pertaining to same, and to approve such Tenant access. Tenant will
also cause its Contractor(s) to coordinate their use of and access to the
foregoing with Landlord's Base Building Contractor, which will have authority to
approve such access; during construction.

         10.1 Landlord will list Tenant's name in the common area Building
directory, if any, and provide Building standard signage on one suite entry door
at Tenant's expense. No other sign, advertisement or notice referring to Tenant
shall be painted, affixed or otherwise displayed on any part of the exterior or
interior of the Building; provided, however, that Tenant may install signs in
the interior of the Premises that are not visible from the exterior of the
Premises. Tenant shall not display any decoration, fitting or other item visible
from tie exterior of the Premises without Landlord's prior approval. If any sign
or item visible from the exterior of the Premises is displayed without
Landlord's approval, then Landlord shall have the tight to remove such item at
Tenant's expense or to require Tenant to do the same.

         10.2 To the extent that Tenant wishes to erect an exterior sign, it may
do so only with the prior written consent of the Landlord, which consent may be
granted, conditioned or withheld in the sole and absolute discretion of
Landlord. If approved, Landlord will establish an annual fee for the value of
such signage rights and Tenant shall also pay the cost of erection of such
signage and such erection shall be treated as an Alteration. Tenant must submit
plans of such signage for review of size, location, color, lighting, weight,
method of attachment and other relevant structural and aesthetic considerations.
Any such approved sign shall be further subject to the relevant requirements of
the City and County for zoning and other legal compliance. This signage right is
non-exclusive, although Tenant shall be entitled to use up to twenty percent
(20%) of the amount of building signage permitted by Landlord and allowed by
applicable building and zoning codes, rules and regulations.

                               TENANT'S EQUIPMENT

         11.1 Tenant may, from time to time during the Term or any extension
hereof, install, maintain, replace, repair, expand, construct and operate in or
upon the Premises and Tenant's Equipment Area and remove therefrom such trade
fixtures and equipment as it may deem necessary or appropriate to its business
operations; provided, any &mage which may be caused to the Premises by the
installation or removal of any of Tenant's trade fixtures or equipment shall be
repaired by Tenant at its expense forthwith. Landlord may impose reasonable
rules and regulations concerning the location, weight and timing and method of
installation of trade fixtures or equipment, whether installed in the Premises
or in Tenant' s Equipment Area.

         11.2 Tenant covenants and agrees that, if directed by the Landlord at
its sole discretion, Tenant shall remove, at Tenant's sole risk and expense, all
fixtures and improvements to the Premises and to the Tenant's Equipment Area
upon the expiration of the Lease Term. If so requested by the Landlord, Tenant
shall restore the Premises and Tenant's Equipment Area to their original
condition, normal wear and tear, and approved structural changes excepted.
Tenant shall also exercise extraordinary care in removing such fixtures and
improvements so as to eliminate damage to the Building, the premises and
property of other tenants and the inconvenience to the operation of the Building
and its tenants.

                              ACCESS AND INSPECTION

         13.1 Tenant shall permit Landlord and its designees to enter the
Premises, without charge therefore and without diminution of the rent payable by
Tenant, to inspect the Premises, to make such alterations and repairs as
Landlord may deem necessary, or to exhibit the Premises to prospective tenants
during the last two hundred seventy (270) days of the Lease Term. Tenant shall
at all times during its occupancy of the Premises provide Landlord duplicates of
the keys to the doors and other points of entry to the Premises. In connection
with any such entry, Landlord shall make reasonable efforts to minimize the
disruption to Tenant's use of the Premises and shall conform to Tenant's

                                       9

reasonable security requirements. Except in an emergency, Landlord shall give
Tenant reasonable prior notice (which shall be in writing, except in an
emergency) of any entry into the Premises pursuant to this Section.

                                    INSURANCE

         14.1 Tenant will not conduct or permit to be conducted any activity, or
place any equipment in or about the Premises or the Building, which will, in any
way, invalidate the insurance coverage in effect or increase the cost of
insurance on or for the Building; and if any invalidation of coverage or
increase in the cost of insurance is stated by any insurance company or by the
applicable Insurance Rating Bureau to be due to any activity or equipment of
Tenant in or about the Premises or the Building, such statement shall be
conclusive evidence that same is due to such activity or equipment and, as a
result thereof, Tenant shall be liable for same and shall reimburse Landlord
therefore upon demand and any such sum shall be considered Additional Rent
payable with the monthly installment of Rent next becoming due.

         14.2 Tenant, at Tenant's expense, shall carry and keep in full force
and effect at all times during the Lease Term for the protection of Tenant,
Landlord and any other persons designated by Landlord pursuant to Section 14.4
hereof commercial general liability insurance including contractual liability
coverage with a combined single limit of at least Three Million Dollars
($3,000,000.00) for each occurrence of bodily or personal injury, death or
property damage and Tenant shall deliver to Landlord a copy of said policy or,
at Landlord's option, a binder or certificate showing the same to be in full
force and effect. It is understood and agreed that liability coverage provided
for hereunder shall extend beyond the Premises to portions of the common area of
the Building used from time to time by Tenant, its agents, employees,
contractors, invitees, licensees, customers, clients, family members and guests,
and, further, shall include contractual liability coverage insuring the
INDEMNITY provisions of this Lease. Notwithstanding the foregoing, during the
construction of the initial improvements, Tenant shall carry such policy with
coverage limitations of at least Five Million Dollars ($5,000,000.00).

         14.3 Tenant, at Tenant's expense, shall further carry a policy of "all
risk" insurance covering all of Tenant's personal property and improvements in
the Premises for not less than the full insurable cost and replacement cost of

the Tenant's personal property and improvements.

         14.4 Said commercial general liability and "all risk" insurance
policies and any other insurance policies carried by Tenant with respect to the
Premises and/or any common areas accessible to Tenant shall (i) be issued in
form acceptable to Landlord by good and solvent insurance companies qualified to
do business in the jurisdiction in which the Building is located and otherwise
reasonably satisfactory to Landlord, (ii) designate as additional named
insureds, besides Tenant as named insured, Landlord, Landlord's managing agent,
Landlord's lender(s) as may exist from time to time, and any other person from
time to tine designated in writing by notice from Landlord to Tenant, (iii) be
written as primary policy coverage and not contributing with or in excess of any
coverage which Landlord may carry, (iv) provide for thirty (30) days prior
written notice to Landlord of any cancellation or other expiration or material
modification of such policy or any defaults thereunder, and (v) contain an
express waiver of any right of subrogation by the insurance company against
Landlord. Neither the issuance of any insurance policy required hereunder nor
the minimum limits specified herein with respect to Tenant's insurance coverage
shall be deemed to limit or restrict in any way Tenant's liability arising under
or out of this Lease.

         14.5 Tenant shall obtain such additional amounts of insurance and
additional types of coverage as Landlord may reasonably request from time to
time. If Tenant fails to comply with any of the insurance requirements of this
Lease, Landlord may obtain such insurance and keep the same in effect, and
Tenant shall pay Landlord as Additional Rent THE premium cost thereof with the
next installment of Rent otherwise due.

         14.6 Notwithstanding anything to the contrary contained hi this Lease,
Landlord and Tenant and all parties claiming under them, to the extent covered
by insurance (or to the extent such party would have been covered by insurance
had such party maintained the insurance required by the terms hereof to be
maintained by such party), each hereby waives any and all rights of recovery,
claim, action and liability against the other, its agents, officers or employees

                                       10

for any loss or damage that may occur to the Building and Premises, or any
improvements thereto, and any personal property owned by them therein, by reason
of fire, the elements or any other cause(s) which could be covered by "all risk"
property insurance, regardless of cause or origin, including negligence of the
other party hereto.

          Landlord shall have the right to remove elevators from service as they
          are required for moving freight or for servicing and/or maintaining
          the elevators and/or the Building.

                           (v) Access to the Premises and the Building 24 hours

jurisdiction in which the Building is located and to provide building security
personnel, equipment, procedures and systems in the Building similar to other
such comparable facilities. Landlord reserves the fight to interrupt, curtail or
suspend the services required to be furnished by Landlord under this Article 15
when the necessity therefore arises by reason of accident, emergency, mechanical
breakdown, or when required by any Law, or for any other cause beyond the
reasonable control of Landlord. Landlord shall use reasonable efforts to
complete all repairs or other work so that Tenant's inconvenience resulting
therefrom may be for as short a period of time as circumstances will permit.

         15.3 Landlord will furnish all services and utilities required by this
Lease only during the normal hours of operation of the Building, unless
otherwise specified herein, in a manner consistent with industry standards for
comparable buildings in the jurisdiction in which the Building is located. The

seven days a week. It is understood and agreed that Landlord shall not be liable
for failure to furnish, or for delay, suspension or reduction in furnishing, any
of the utilities, services or other manner of thing required to be furnished by
Landlord hereunder, if such failure to furnish or delay, suspension or reduction
in furnishing same is caused by breakdown, maintenance, repairs, strikes,
scarcity of labor or materials, acts of God, Landlord's compliance with
governmental regulation or legislation or judicial or administrative orders or
from any other cause whatsoever; provided, however, that Landlord shall, in the
event of a breakdown, use reasonable diligence to repair all equipment owned by
Landlord and all building standard equipment furnished by Landlord which is
required to provide such utilities and services.

by Tenant or Invitees in or about the Premises or the Building shall be at the
sole risk of Tenant, and Landlord shall not in any manner be held responsible
therefore. If any employee of Landlord receives any package or article delivered

"Building" shall be deemed to include the Land. Notwithstanding the foregoing
provisions of this Section, Landlord shall not be released from liability, if
any, to Tenant for any damage caused by Landlord's willful misconduct or gross
negligence, to the extent such damage is not covered by insurance carried by
Tenant or required to be carried by Tenant.

         16.4 Tenant shall not have the right to offset or deduct the amount
allegedly owed to Tenant pursuant to any claim against Landlord from any rent or
other sum payable to Landlord. Tenants sole remedy for recovering upon such
claim shall be to institute an independent action against Landlord.

         16.5 Notwithstanding anything to the contrary contained herein, if
Tenant or any Invitee is awarded a money judgment against Landlord, then
recourse for satisfaction of such judgment shall be limited to execution against

judgment or specific performance will be Tenant's sole right and remedy in any
dispute as to whether Landlord has breached such obligation.

         16.7 Landlord shall not be liable in any manner to Tenant, its agents,
employees, invitees or visitors for any injury or damage to Tenant, Tenants
agents, employees, invitees or visitors, or their property, caused by the
criminal or intentional misconduct of third parties or of Tenant, Tenant's
employees, agents, invitees or visitors. All claims against Landlord for any
such damage or injury are hereby expressly waived by Tenant, and Tenant hereby
agrees to hold harmless and indemnify Landlord from all such damages and the
expense of defending all claims made by Tenant's employees, agents, invitees, or
visitors arising out of such acts.

                                      RULES

         17.1 Tenant and its Invitees shall at all times abide by and observe
the rules set forth in EXHIBIT E. Tenant and its Invitees shall also abide by
and observe any other rule that Landlord may reasonably promulgate from
time-to-time for the operation and maintenance of the Building, provided that
notice thereof is given and such rule is not inconsistent with the provisions of
this Lease. Except for Landlord's obligation to enforce the rules in a
non-discriminatory manner, nothing contained in this Lease shall be construed as
imposing upon Landlord any duty to enforce such rules or any condition or
covenant contained in any other lease against any other tenant, and Landlord
shall not be liable to Tenant for the violation of such rules or regulations by
any other tenant or its invitees.

                                   ARTICLE 18
                              DAMAGE OR DESTRUCTION

         18.1 If the Premises or the Building are totally or partially damaged
or destroyed, thereby rendering the Premises totally or partially inaccessible
or unusable, then Landlord shall diligently repair and restore the Premises and
the Building to substantially the same condition they were in prior to such
damage or destruction; provided, however, that if in Landlord's reasonable
judgment such repair and restoration cannot be completed within one hundred
eighty (180) days after the adjustment of the loss in connection with such
damage or destruction, then Landlord shall have the right, at its sole option,
to terminate this Lease by giving written notice of termination within
forty-five (45) days after the occurrence of such. damage or destruction.

         18.2 If Landlord determines, in its reasonable judgment, that the
repairs and restoration cannot be substantially completed within one hundred
eighty (130) days after the date of adjustment of the loss in connection with
such damage or destruction, Landlord shall promptly notify Tenant of such
determination. For a period of thirty (30) days after receipt of such
determination, Tenant shall have the right to terminate this Lease by providing
written notice to Landlord. If Tenant does not elect to terminate this Lease
within such thirty (30) day period, and provided that Landlord has not elected
to terminate this Lease, Landlord shall proceed to repair and restore the
Premises and the Building. Notwithstanding the foregoing, Tenant shall not have
the right to terminate this Lease if the act or omission of Tenant or any of its
invitees shall have caused the damage or destruction.

                                       13
<PAGE>

         18.3 If this Lease is terminated pursuant to Section 18.1 or 18.2
above, then all rent shall be apportioned (based on the portion of the Premises
which is usable after such damage or destruction) and paid to the date of
termination. If this Lease is not terminated as a result of such damage or
destruction, then until such repair and restoration of the Premises are
substantially complete, Tenant shall be required to pay the Base Rent and
additional rent only for the portion of the Premises that is usable while such
repair and restoration are being made. Landlord shall bear the expenses of
repairing and restoring the Premises and the Building; provided, however, that
Landlord shall not be required to repair or restore any Alteration previously
made by Tenant or any of Tenant's trade fixtures, furnishings, equipment or
personal property; and provided further that if such damage or destruction was
caused by the act or omission of Tenant or any Invitee, then Tenant shall pay
the amount by which such expenses exceed the insurance proceeds, if any,
actually received by Landlord on account of such damage or destruction.

         18.4 Notwithstanding anything herein to the contrary, Landlord shall
not be obligated to restore the Premises or the Building and shall have the
right to terminate this Lease if (a) the holder of any Mortgage fails or refuses
to make insurance proceeds available for such repair and restoration, (ii)
zoning or other applicable laws or regulations do not permit such repair and.
restoration, or (c) the cost of repairing and restoring the Building would
exceed fifty percent (50%) of the replacement value of the Building, whether or
not the Premises are damaged or destroyed, provided the leases of all other
tenants in the Building are similarly terminated.

         18.5 Notwithstanding the foregoing Sections of this Article 18,
Landlord shall not be obligated to restore the Tenant Work which was a part of
the work required to be performed under EXHIBIT D attached hereto. Rather, the
restoration of such Tenant Work shall be the sole expense and responsibility of
Tenant.

                                   ARTICLE 19
                                  CONDEMNATION

         19.1 If one-third or more of the Premises or occupancy thereof shall be
permanently taken or condemned by any governmental or quasi-governmental
authority for any public or quasi-public use or purpose or sold under threat of
such a taking or condemnation (collectively, "condemned'), then this Lease shall
terminate on the date title thereto vests in such authority and rent shall be
apportioned as of such date. If less than one-third of the Premises or occupancy
thereof is condemned, then this Lease shall continue in force and effect as to
the part of the Premises not condemned, except that as of the date title vests
in such authority Tenant shall not be required to pay the Base Rent and
additional rent with respect to the part of the Premises condemned.

         19.2 All awards, damages and other compensation paid by such authority
on account of such condemnation shall belong to Landlord, and Tenant assigns to
Landlord all rights to such awards, damages and compensation. Tenant shall not
make any claim against Landlord or the authority for any portion of such award,
damages or compensation attributable to damage to the Premises, value of the
unexpired portion of the Lease Term, loss of profits or goodwill, leasehold
improvements or severance damages. Nothing contained herein, however, shall
prevent Tenant from pursuing a separate claim against the authority for the
value of furnishings and trade fixtures installed in the Premises at Tenant's
expense and for relocation expenses, provided that such claim shall in no way
diminish the award, damages or compensation payable to or recoverable by
Landlord in connection with such condemnation.

                                   ARTICLE 20
                                     DEFAULT

         20.1 Each of the following shall constitute an Event of Default: (a)
Tenant's failure to make any payment of the Base Rent, Additional Rent or other
sum on or before such payments due date, provided that, on up to two (2)
occasions in any twelve (12) month period, there shall exist no Event of Default
unless Tenant shall have been given written notice of such failure and shall not
have made the payment within five (5) days following the giving of such notice;
(b) Tenant's violation or failure to perform or observe any other covenant or
condition within twenty (20) days after notice thereof from Landlord; (c)
Tenant's vacation or abandonment of the Premises; (d) an Event of Bankruptcy as
specified in Article 21 with respect to Tenant, any general partner or member or
managing member of Tenant (a "General Partner") or any Guarantor; or (e)
Tenant's dissolution or liquidation. 11 prior to the commencement of the Lease
Term, Tenant notifies Landlord of or otherwise unequivocally demonstrates an
intention to repudiate this Lease, Landlord may, at its option, consider such

                                       14
<PAGE>

anticipatory repudiation an Event of Default. In addition to any other remedies
available to it hereunder or at law or in equity, Landlord may retain all rent
paid upon execution of the Lease and the security deposit, if any, to be applied
to damages of Landlord incurred as a result of such repudiation, including
without limitation attorneys' fees, brokerage fees, costs of reletting, and loss
of rent. Tenant shall pay in full for all tenant improvements constructed or
installed within the demised premises to the date of the breach, and for
materials ordered at its request for the Premises.
         20.2 If there shall be an Event of Default, including an Event of
Default prior to the Rent Commencement Date, then Landlord shall have the right,
at its stole option, to terminate this Lease. In addition, with or without
terminating this Lease, Landlord may re-enter, terminate Tenant's right of
possession and take possession of the Premises. The provisions of this Article
shall operate as a notice to quit, any other notice to quit or of Landlord's
intention to re-enter the Premises being hereby expressly waived. If necessary,
Landlord may proceed to recover possession of the Premises under and by virtue
of the laws of the jurisdiction in which the Building is located, or by such
other proceedings, including re-entry and possession, as may be applicable. If
Landlord elects to terminate this Lease and/or elects to terminate Tenant's
right of possession, then everything contained in this Lease to be done and
performed by Landlord shall cease, without prejudice, however, to Landlord's
right to recover from Tenant all rent and other sums accrued through the later
of termination or Landlord's recovery of possession. Whether or not this Lease
and/or Tenant's right of possession is terminated, Landlord may, but shall not
be obligated to, relet the Premises or any part thereof alone or together with
other premises, for such rent and upon such terms and conditions (which may
include concessions or free rent and alterations of the Premises) as Landlord,
in its sole discretion, may determine, but Landlord shall not be liable for, nor
shall Tenant's obligations be diminished by reason of, Landlord's failure to
relet the Premises or collect any rent due upon such reletting. Whether or not
this Lease is terminated, Tenant nevertheless shall remain liable for any Base
Rent, Additional Rent or damages which may be due or sustained prior to such
default, all costs, fees and expenses (including without limitation reasonable
attorneys' fees, brokerage fees and expenses incurred in placing the Premises in
first-class rentable condition) incurred by Landlord in pursuit of its remedies
and in renting the Premises to others from time to time. Tenant shall also be
liable for additional damages which at Landlord's election shall be either:

                  (a) an amount equal to the Base Rent and Additional Rent which
         would have become due during the remainder of the Lease Term, less the
         amount of rental, if any, which Landlord receives during such period
         from others to whom the Premises may be rented (other than any
         additional rent payable as a result of any failure of such other person
         to perform any of its obligations), which damages shall be computed and
         payable in monthly installments, in advance, on the first day of each
         calendar month following Tenant's default and continuing until the date
         on which the Lease Term would have expired but for Tenant's default.
         Separate suits may be brought to collect any such damages for any
         month(s), and such suits shall not in any manner prejudice Landlord's
         right to collect any such damages for any subsequent month(s), or
         Landlord may defer any such suit until after the expiration of the
         Lease Term, n which event the cause of action shall be deemed not to
         have accrued until the expiration of the Lease Term; or

                  (b) an amount equal to the present value (as of the date of
         the termination of this Lease) of the difference between (i) the Base
         Rent and Additional Rent which would have become due during the
         remainder of the Lease Term, aid (ii) the fair market rental value of
         the Premises for the same period, which damages shall be payable to
         Landlord in one lump sum on demand. For purpose of this Section,
         present value shall be computed by discounting at a rate equal to one
         (I) whole percentage point above the discount rate then in effect at
         the Federal Reserve Bank of New York (or, if such rate is not
         reasonably available, such substitute rate as Landlord reasonably shall
         select).

         Tenant waives any right of redemption, re-entry or restoration of the
operation of this Lease under any present or future law, including any such
right which Tenant would otherwise have if Tenant shall be dispossessed for any
cause.

         20.3 Landlord's rights and remedies set forth in this Lease are
cumulative and in addition to Landlord's other rights and remedies at law or in
equity, including those available as a result of any anticipatory breach of this
Lease. Landlord's exercise of any such right or remedy shall not prevent the

                                       15
<PAGE>

concurrent or subsequent exercise of any other right or remedy. Landlord's delay
or failure to exercise or enforce any of Landlord's rights or remedies or
Tenant's obligations shall not constitute a waiver of any such rights, remedies
or obligations. Landlord shall not be deemed to have waived any default unless
such waiver expressly is set forth in an instrument signed by Landlord. If
Landlord waives in writing any default, then such waiver shall not be construed
as a waiver of any covenant or condition set forth in this Lease except as to
the specific circumstances described in such written waiver. Neither Tenant's
payment of a lesser amount than the sum due hereunder nor Tenant's endorsement
or statement on any check or letter accompanying such payment shall be deemed an
accord and satisfaction, and Landlord may accept the same without prejudice to
Landlord's right to recover the balance of such sum or to pursue any other
remedy available to Landlord. Landlord's re-entry and acceptance of keys shall
not be considered an acceptance of a surrender of this Lease.

         20.4 If more than one natural person and/or entity shall execute this
Lease as Tenant, then the liability of each such person or entity shall be joint
and several. Similarly, if Tenant is a general partnership or other entity the
partners or members of which are subject to personal liability, then the
liability of each such partner or member shall be joint and several.

         20.5 If Tenant fails to make any payment to any third party or to do
any act herein required to be made or done by Tenant, then Landlord may, but
shall not be required to, make such payment or do such act. Landlord's taking
such action shall not be considered a cure of such failure by Tenant or prevent
Landlord from pursuing any remedy to which it is otherwise entitled in
connection with such failure. If Landlord elects to make such payment or do such
act, then all expenses incurred, plus interest thereon at a rate per annum (the
"Default Rate") which is five (5) whole percentage points higher than the prime
rate published from time to time in the Money Rates section of The Wall Street
Journal (or, if such rate is not reasonably available, such substitute rate as
Landlord reasonably shall select), from the date incurred to the date of payment
thereof by Tenant, shall constitute additional rent.

         20.6 If Tenant fails to make any payment of the Base Rent, Additional
Rent or any other sum payable to Landlord within five (5) days after the date
such payment is due and payable, then Tenant shall pay a late charge of five
percent (5%) of the amount of such payment. In addition, such payment and such
late fee shall bear interest at the Default Rate from the date such payment was
due to the date of payment thereof.

                                   ARTICLE 21
                                   BANKRUPTCY

         21.1 The following shall be Events of Bankruptcy under this Lease: (a)
Tenant's, a Guarantor's, a General Partner's, or a Managing Member's becoming
insolvent, as that term is defined in Title 11 of the United States Code (the
"Bankruptcy Code"), or under the insolvency laws of any state (the "Insolvency
Laws"); (b) appointment of a receiver or custodian for any property of Tenant, a
Guarantor, a General Partner or a Managing Member, or the institution of a
foreclosure or attachment action upon any property of Tenant, a Guarantor, a
General Partner; or a Managing Member (c) filing of a voluntary petition by
Tenant, a Guarantor, a General Partner or a Managing Member under the provisions
of the Bankruptcy Code or Insolvency Laws; (d) filing of an involuntary petition
against Tenant, a Guarantor, a General Partner or a Managing Member as the
subject debtor under the Bankruptcy Code or Insolvency Laws, which either (i) is
not dismissed within thirty (30) days of filing, or (ii) results in the issuance
of an order for relief against the debtor; or (e) Tenant's, a Guarantor's, a
General Partners or a Managing Member's making or consenting to an assignment
for the benefit of creditors or a composition of creditors.

         21.2 (a) Upon occurrence of an Event of Bankruptcy, Landlord shall have
all rights and remedies available pursuant to Article 20; provided, however,
that while a case in which Tenant is the subject debtor under the Bankruptcy
Code is pending, Landlord shall not exercise its rights and remedies pursuant to
Article 20 so long as (i) the Bankruptcy Code prohibits the exercise of such
rights and remedies, and (ii) Tenant or its trustee in Bankruptcy ("Trustee") is
in compliance with the provisions of Section 21.2(b).

                  (b) If Tenant becomes the subject debtor in a ease pending
         under the Bankruptcy Code, then Landlord's right to terminate this
         Lease pursuant to Section 21.2(a) shall be subject, to the extent

<PAGE>

         required by the Bankruptcy Code, to any rights of Trustee to assume or
         assign this Lease pursuant to the Bankruptcy Code. Trustee shall not
         have the right to assume or assign this Lease unless Trustee promptly
         (1) cures all defaults under this Lease, (2) compensates Landlord for
         monetary damages incurred as a result of such defaults, (3) provides
         adequate assurance of future performance on the part of Tenant as
         debtor in possession or of the assignee of Tenant, and (4) complies
         with all other requirements of the Bankruptcy Code. This Lease may be
         terminated in accordance with Section 21.2(a) if the foregoing criteria
         for assumption or assignment are not met, or if Tenant, Trustee or such
         assignee defaults under this Lease after such assumption or assignment.
         Adequate assurance of future performance, as used in this Section
         21.2(b), shall mean that all of the following minimum criteria must be
         met: (A) Tenant's gross receipts in the ordinary course of business
         during the thirty (20) day period immediately preceding the initiation
         of the case under the Bankruptcy Code must be greater than two (2)
         times the next monthly installment of the Base Rent and additional
         rent; (B) both the average and median of Tenant's monthly gross
         receipts in the ordinary course of business during the six (6) month

         advance of the performance or provision of such services; (D) Trustee
         must agree that Tenant's business shall be conducted in a first-class
         manner, and that no liquidating sale, auction or other non-first-class
         business operation shall be conducted in the Premises; (E) Trustee must
         agree that the use of the Premises as stated in this Lease shall remain
         unchanged and that no prohibited use shall be permitted; (F) `Trustee
         must agree that the assumption or assignment of this Lease shall not
         violate or affect the rights of other tenants in the Building; (G)
         Trustee must pay to Landlord at the time the next monthly installment
         of the Base Rent is due, in addition to such installment, an amount
         equal to the monthly installments of the Base Rent and additional rent
         due for the next six (6) months thereafter, such amount to be held as a
         security deposit; and (H) all assurances of future performance

                                   ARTICLE 22
                                  SUBORDINATION

         22.1 This Lease is subject and subordinate to the lien, previsions,
operation and effect of all mortgages, deeds of trust, ground leases or other
security instruments which may now or hereafter encumber the Building or the
Land (collectively "Mortgages"), to all funds and indebtedness intended to be
secured thereby, and to all renewals, extensions, modifications, recastings or
refinancings thereof The holder of any Mortgage to which this Lease is
subordinate shall have the right (subject to any required approval of the
holders of any superior Mortgage) at any time to declare this Lease to be
superior to the lien, provisions, operation and effect of such Mortgage and
Tenant shall execute, acknowledge and deliver all documents required by such
holder in confirmation thereof.

         22.2 In confirmation of the foregoing subordination, Tenant shall at
Landlord's request, but in no event later than five (5) business days following
a request therefore, execute and deliver any requisite or appropriate document.
Tenant waives the provisions of any statute or rule of law now or hereafter in
effect which may give or purport to give Tenant any right to terminate or
otherwise adversely affect this Lease or Tenant's obligations in the event any
such foreclosure proceeding is prosecuted or completed or in the event the Land,
the Building or Landlord's interest therein is sold at a foreclosure sale or by
deed Li lieu of foreclosure. If this Lease is not extinguished upon such sale or
by the purchaser following such sale, then, at the request of such purchaser,
Tenant shall attorn to such purchaser and shall recognize such purchaser as the
landlord under this Lease. Upon such attornment such purchaser shall not be (a)
bound by any payment of the Base Rent or additional rent more than one (1) month
in advance, (b) bound by any amendment of this Lease made without the consent of
the holder of each Mortgage existing as of the date of such amendment, (c)
liable for damages for any breach, act or omission of any prior landlord, or (d)
subject to any offsets or defenses which Tenant might have against any prior
landlord; provided, however, that after succeeding to Landlord's interest, such

                                       17
<PAGE>

purchaser shall perform in accordance with the terms of this Lease all
obligations of Landlord arising after the date such purchaser acquires title to
the Building. Within fifteen (15) days after the request of such purchaser,
Tenant shall execute, acknowledge and deliver any requisite or appropriate
document submitted to Tenant confirming such attornment.

         22.3 (a) After Tenant receives notice from any person, firm or other
entity that it holds a Mortgage on the Building or the Land, no notice from
Tenant to Landlord alleging any default by Landlord shall be effective unless
and until a copy of the same is given to such holder, provided that Tenant shall
have been furnished with the name and address of such holder. Any such holder
shall have thirty (30) days after its receipt of notice from Tenant of a default
by Landlord under this Lease to cure such default before Tenant may exercise any
remedy hereunder. The curing of any of Landlord's defaults by such holder shall
be treated as performance by Landlord.

                  (b) In the event that any lender providing construction,
         interim or permanent financing or any refinancing for the Building
         requires, as a condition of such financing, that modifications to this
         Lease be obtained, and provided that such modifications (i) are
         reasonable; (ii) do not adversely affect in a material manner Tenant's
         use of the Premises as herein permitted; and (iii) do not increase the
         rent and other sums to be paid by Tenant hereunder, Landlord may submit
         to Tenant a written amendment to this Lease incorporating such required
         changes, and Tenant hereby covenants and agrees to execute, acknowledge
         and deliver such amendment to Landlord within fifteen (15) days of
         Tenant's receipt thereof.

                                  HOLDING OVER

         23.1 If Tenant does not immediately surrender the Premises upon the
expiration or earlier termination of the Lease Term, then Tenant shall become a
tenant by the month and the rent shall be increased to equal the greater of (a)
fair market rent for the Premises, or (b) double the Base Rent, additional rent
and other sums that would have been payable pursuant to the provisions of this
Lease if the Lease Term had continued during such holdover period. Such rent
shall be computed on a monthly basis and shall be payable on the first day of
such holdover period and the first day of each calendar month thereafter during
such holdover period until the Premises have been vacated. Landlord's acceptance
of such rent shall not constitute consent by Landlord to tenant's holdover
possession and shall not in any manner adversely affect Landlords other rights
and remedies, including Landlord's right to evict Tenant and to recover damages.

                                   ARTICLE 24
                              COVENANTS OF LANDLORD

entrances, passageways, doors, doorways, corridors, elevators, stairs, toilets
or other public parts of the Building; (c) to erect, use and maintain pipes and
conduits in and through the Premises; and (d) to grant to anyone the exclusive
right to conduct any particular business in the Building act inconsistent with
Tenant's permitted use of the Premises. Landlord shall also have the right to
construct a building on the property owned by Landlord adjacent to the Building
and to install connections and/or passageway's linking the Building to such
neighboring building. Landlord may exercise any or all of the foregoing rights
without being deemed to be guilty of an eviction, actual or constructive, or a
disturbance of Tenant's business or use or occupancy of the Premises. In
addition, Landlord reserves for itself the exclusive use of all portions of the
roof of the Building, except those portions of the roof specifically designated
Tenant's Equipment Area.

                                     PARKING

         25.1 During the Lease Term, Tenant shall have the right to use the
parking spaces as described in the Rider. Tenant shall not sell, assign or
permit anyone other than Tenant's personnel to use any of the aforesaid parking

<PAGE>

permitted sublease of the Premises. Tenant and its personnel shall comply with
all reasonable rules and regulations promulgated by Landlord or Landlord's
parking area manager for the orderly functioning of the Building's parking

                  2.1      ELECTRICAL SERVICE. Pursuant to the Master
                           Utilization Plan being prepared for the Property,
                           Florida Power & Light Company ("FP&L") shall
                           construct two (2) underground 13.2 volt electrical

                                 R E C I T A L S

         A.       NAP of the Americas, Inc. ("Tenant") is desirous of entering
                  into that certain lease of even date herewith with Landlord
                  relating to certain premises known as 149,184 square feet of

                  referred to as the "Lease").

         B.       Guarantor has requested that Landlord enter into the Lease.

         C.       Landlord has declined to enter into the Lease unless Guarantor
                  guarantees the Lease.

         NOW, THEREFORE, to induce Landlord to enter into the Lease, Guarantor
hereby agrees as follows:

         1. UNCONDITIONAL GUARANTY. Guarantor unconditionally guarantees to
Landlord and the successors and assigns of Landlord the full and punctual
payment, performance and observance by Tenant of all of the terms, covenants and
conditions in the Lease to be kept, performed or observed by Tenant. 1f at any
time, Tenant shall default in the performance or observance of any of the terms,
covenants or conditions in the Lease to be kept, performed or observed by
Tenant, including, without limitation, the payment of any rent or other charge,
Guarantor will keep, perform and observe the same, as the case may be, in place
and stead of Tenant. It is understood and agreed that the use of the word
"Lease" herein shall include the Basic Lease Information Rider ("Rider"), all
exhibits, and all schedules attached to the Lease.

         2. WAIVER OF NOTICE; NO RELEASE OF LIABILITY. Any act of Landlord or
the successors or assigns of Landlord consisting of the giving of any consent to
any manner or thing relating to the Lease, or the granting of any indulgences or
extensions of time to Tenant, may be done without any notice to Guarantor and
without releasing or diminishing the obligations of Guarantor hereunder. The
obligations of Guarantor hereunder shall not be released or diminished by
Landlord's receipt, application or release of security given for the performance
and observance of covenants and conditions in the Lease to be performed or
observed by Tenant, or by any modifications of the Lease. The liability of
Guarantor hereunder shall in no way be affected by (a) the release or discharge
of Tenant in any creditors, receivership, bankruptcy or other proceedings, (b)
the impairment, limitation or modification of the liability of Tenant or the
estate of Tenant in bankruptcy, or of any remedy for the enforcement of Tenant's
liability under the Lease resulting from the operation of any present or future
provision of the Federal Bankruptcy Code or other statute or from the decision
in any court; (c) the rejection or disaffirmance of the Lease in any such
proceedings; (d) the assignment or transfer of the Lease by Tenant; (e) any
disability or other defense of Tenant; (f) the cessation from any cause
whatsoever of the liability of Tenant; or (g) the exercise by Landlord of any
rights or remedies reserved to Landlord under the Lese, provided or permitted by

         3. JOINDER: STATUTE OF LIMITATIONS. Guarantor agrees that it may be
joined in any action against Tenant in connection with the obligations of Tenant
under the Lease as covered by this Guaranty and recovery may be had against
Guarantor in any such action or Landlord may enforce the obligations of
Guarantor hereunder without first taking any action whatsoever against Tenant or
its successors and assigns, or pursue any other remedy or apply any security it
may hold, and Guarantor hereby waives all rights to assert or plead at any time
any statute of limitations as relating to the Lease, the obligations of
Guarantor hereunder and any and all surety or other defenses in the nature
thereof.

         4. LIMITATION OF CLAIMS; SUBORDINATION. Until all of the covenants and
conditions in the Lease on Tenant's part to be performed and observed are fully
performed and observed, Guarantor:

ineffective or unenforceable by any court of competent jurisdiction, or in the
event of any limitation of liability of Guarantor herein other than as expressly
provided herein, then Guarantor shall be deemed to be a tenant under the Lease
with the same force and effect as if Guarantor were expressly named as a joint
and several tenant therein with respect to the obligations of Tenant thereunder
hereby guaranteed.

changed, modified, amended or waived by agreement between Landlord and Tenant at

Guarantor. This Guaranty shall guarantee the performance of the Lease as so
changed, modified, amended or waived. Any assignment of the Lease (as permitted
by the Lease) shall not affect this Guaranty and if Landlord disposes of its
interest in the Lease, "Landlord", as used in this Guaranty, shall mean
Landlord's successors and assigns.

legal or other disability of Tenant and any other party to the Lease, and

Guaranty, and further waives all notices of the existence, creation, or
incurring of new or additional obligations.

         8. NO WAIVER BY LANDLORD. No delay on the part of Landlord in
exercising any right hereunder or under the Lease shall operate as a waiver of
such right or of any other right of Landlord under the Lease or hereunder, nor
shall any delay, omission or waiver on any one or more occasions be deemed a bar
to or a waiver of the same or any other right on any other future occasion.

         9. JOINT AND SEVERAL LIABILITY. If there is more than one undersigned
Guarantor, the term "Guarantor", as used herein, shall include all of such

license to use and copy the Deliverable for NAPA internal business purposes.
This license shall include a license to use any Telcordia newly-created
Invention, Work of Authorship or other intellectual property to the extent
necessary for NAPA to meet the purposes set forth in this Agreement or in an
applicable Work Statement. This license shall further include the right to
provide copies of the Deliverable to consultants, contractors or suppliers who
are hired to carry out recommendations within the Deliverable as long as such
consultant, contractor or supplier is subject to an agreement requiring
confidentiality of the Deliverable, and which limits the use of the Deliverable
by the consultant, contractor or supplier to providing services to NAPA. NAPA
shall include a Telcordia copyright notice on all copies of Deliverables. The
services and any Deliverables are not "work for hire."

4.2 OWNERSHIP OF NEWLY-CREATED INTELLECTUAL PROPERTY. Any patentable or
unpatentable discoveries, ideas, including methods, techniques, know-how,
concepts, or products ("Invention"); or any works fixed in any medium of
expression, including copyright and mask work rights ("Works of Authorship"); or
any other intellectual property created by Telcordia during the course of the
Services shall be the sole and exclusive property of Telcordia. Any Inventions,
Works of Authorship or other intellectual property created jointly by Telcordia
and NAPA during the course of the Services shall be the joint property of
Telcordia and NAPA, each party having full licensing rights with no obligation
of accounting to the other party.

4.3 NO RIGHTS BY IMPLICATION. Except as set forth above, no direct or indirect
ownership interest or license rights in Inventions, Works of Authorship or other
intellectual property including software or patents are granted or created by
implication in this Agreement. Any grant of an ownership interest or license
rights in an Invention, Work of Authorship or other intellectual property
including software or patents must be negotiated in a separate agreement.
Telcordia will use reasonable efforts to inform NAPA of any Telcordia owned
Inventions, Works of Authorship or other intellectual property that Telcordia
believes may be necessary for NAPA to use the Deliverable or to meet the
purposes set forth in this Agreement or in an applicable Work Statement.

services for others, including providing the same or similar conclusions and

or will provide to Telcordia in order for Telcordia to complete the Services and
to create the Deliverables identified hereunder. NAPA further represents and

the other that it shall have obtained, prior to the commencement of the

and correct the non-conforming Deliverables to conform to this standard; or (2)
refund to NAPA that portion of the amounts received by Telcordia attributable to
the nonconforming Services and/or Deliverables. No warranty claim shall be
effective unless NAPA has delivered to Telcordia written notice specifying in
detail the non-conformities within thirty (30) days after performance of the
non-conforming Services or tender of the non-conforming Deliverables. The remedy
set forth in this Section 7.1 is the sole and exclusive remedy for breach of the

consent may not be unreasonably withheld.

9.4 WAIVER. The failure of either party at any time to enforce any of the
provisions of this Agreement or any right under this Agreement, or to exercise

Agreement. The failure of either party to exercise any rights or options under
the terms or conditions of this Agreement shall not preclude or prejudice the
exercising of the same or any other right under this Agreement.

       10.1.1 Reexport of Technical Data. NAPA acknowledges that any commodities
       and/or technical data provided under this Agreement shall be subject to
       the Export Administration Regulations ("the EAR") administered by the
       U.S. Commerce Department http://www.bxa.doc.gov (The Bureau of Export
       Administration home page) and that any export or reexport thereof must be
       in compliance with the EAR. NAPA agrees that it shall not export or
       reexport, directly or indirectly, either during the term of this
       Agreement or after its expiration, any commodities and/or technical data
       (or direct products thereof) provided under this Agreement in any form to
       destinations in Country Groups D:1 or E:2, as specified in Supplement No.
       1 to Part 740 of the EAR, and as modified from time to time by the U.S.

       or embargoed under U.S. law.

       10.1.2 GOVERNMENTAL APPROVALS AND CONSENTS. This Agreement is subject to
       the receipt of any approvals and/or consents required by United States
       and foreign government agencies and authorities, including but not
       limited to the export control laws and regulations of the United States,
       as may be required for the consummation of the transactions contemplated
       by this Agreement. Telcordia shall have no liability to NAPA for failure
       to deliver any product or service under this Agreement as a result of the
       refusal of United States or foreign governmental agencies to issue any
       necessary approvals and consents for the export of any such product or
       service.

10.2 EXPORT CONTROL. Telcordia shall notify NAPA of any restricted technology
that may be controlled for export purposes. Any technology provided by Telcordia
that is controlled for export purposes, may require prior approval by the
appropriate U.S. Government agency, either the U.S. Department of State (DOS) or
the U.S. Department of Commerce (DOC). Should this technology provided by
Telcordia be export controlled, NAPA will be bound by U.S. export statutes and
regulations and shall comply with all export control requirements. NAPA and/or
Telcordia shall have full responsibility for any required export licenses.

10.3 IMMIGRATION AND ENTRY REQUIREMENTS. NAPA shall obtain and supply Telcordia

       employees are required to pay any non-United States taxes in connection
       with this Agreement, including those listed above, the fees under this
       Agreement shall be correspondingly increased.

       10.5.2 If, after the effective date of this Agreement or any applicable
       Work Statement hereto, there are changes or developments which may result
       in an increase in any non-United States taxes, and/or any new non-United
       States taxes or assessments are levied by a government other than the
       United States, or if the methods of administering or the rates of any
       such taxes or assessments are changed, and such new taxes, assessments or
       changes result in an increased potential non-United States tax liability
       for Telcordia, its subcontractors, and/or their respective employees
       under this Agreement, the fees under this Agreement shall be
       correspondingly increased.

             AMENDMENT TO THE PROFESSIONAL SERVICES MASTER AGREEMENT
                      BETWEEN NAP OF THE AMERICAS, INC. AND
                          TELCORDIA TECHNOLOGIES, INC.

This amendment to the Professional Services Master Agreement, executed on
September 1, 2000, between NAP of the Americas, Inc. ("NAPA"), a wholly owned
subsidiary of Terremark Worldwide, Inc. and Telcordia Technologies, Inc.
("Telcordia") ("Agreement") (Contract No. 20000822JS113827) shall amend the
Agreement as follows:

1.       THE PREAMBLE OF THE AGREEMENT ON PAGE 1 SHALL BE MODIFIED TO DELETE THE
         LAST TWO SENTENCES WHICH READ AS FOLLOWS:

"Notwithstanding the foregoing, the Parties agree that the terms and conditions
of the financing structure ("Financing Agreement"), currently under negotiation
between the Parties, shall replace and supercede the Billing Terms and
conditions under Section 2.2 of this Master Agreement as governing and
controlling each Work Statement retroactively from the effective date of the
Master Agreement. The Parties further acknowledge and agree that the Financing
Agreement will address any necessary adjustment in terms, including price,
required for such application, and shall be mutually agreed to by the Parties."

2.       UNDER SECTION 2.1 FEES AND EXPENSES, THE LAST SENTENCE SHALL BE DELETED
         AND REPLACED WITH THE FOLLOWING:

"From the date of execution of this Agreement, all labor provided by Telcordia
on a time and materials basis, shall be reimbursed on an hourly basis, based on
the actual hours incurred multiplied by the hourly rates for engineering and
consulting services as set forth on page 4 of WS 001 executed on September 1,
2000 (the "Rates"), which Rates are represented by Telcordia to be the lowest or
equal to the lowest rates charged to any Telcordia non-governmental customer for
consulting and engineering services ("Preferred Pricing"). The Rates will not be
increased before January 1, 2002, even if Telcordia increases its Preferred
Pricing rates to other customers. On or after January 1, 2002. NAPA shall be
charged the then prevailing Preferred Pricing (i.e., Preferred Pricing which
takes into account rate increases to other non-governmental customers between
the time of the execution of this Amendment and January 1, 2002).
Notwithstanding the Preferred Pricing guaranty set for herein, NAPA acknowledges
that the Preferred Pricing model does not take into account services for which
Telcordia does not charge or for which it charges rates substantially and
significantly lower than the Rates because the services are being rendered for
certain customers in connection with and related to purchases of Telcordia
provided and/or third party software and/or hardware bundled with ancillary
services.

For any value added services related to the operation of the NAP provided by
Telcordia beyond basic NAP services, Telcordia shall provide pricing as good as
or better than other non-governmental customers which are (1) similarly situated
to NAP of the Americas. Inc. (2) for similar types of services, solutions and
products, and (3) for similar volume or usages.
<PAGE>
3.       UNDER SECTION 2.2 BILLING, THE LAST SENTENCE SHALL BE MODIFIED TO
         REPLACE THIRTY (30) DAYS WITH FORTY FIVE (45) DAYS.

4.       SECTION 9 GENERAL, SHALL BE AMENDED TO ADD THE FOLLOWING AFTER SECTION
         9.11:

"9.12 TERMINATION FOR CAUSE.

Either party shall have the right, without prejudice to its other rights or
remedies, to terminate the Agreement or any Work Statement under this Agreement
upon written notice to the other party as provided below, if the other party:

         (a) is in material breach of any of its material obligations under this
Agreement or the affected Work Statement and either the breach is incapable of
remedy or the breaching party has failed to remedy such breach or failed to
commence steps to remedy such breach within the thirty (30) calendar day period
after receiving written notice, which describes the breach in reasonable detail,
requiring it to remedy such breach; or

         (b) assigns its assets, or a substantial part of its assets for the
benefit of its creditors, or admits in writing its inability to pay debts as
they mature, or a trustee or receiver is appointed for a substantial part of its
assets, or a bankruptcy proceeding is instituted against the other party which
is acquiesced in and is not dismissed within sixty (60) calendar days, or
results in an adjudication of bankruptcy."

"9.13 TERMINATION FOR CONVENIENCE.

NAPA shall have the right to terminate any Work Statement for convenience on not
less than thirty (30) calendar days prior written notice to Telcordia. Upon
Telcordia's receipt of notice of termination for convenience from NAPA,
Telcordia and NAPA shall meet to determine the extent of the Services and
Deliverables to be provided prior to the effective date of termination. In the
event the parties fail to agree to the extent of the Services and Deliverables
to be provided prior to the effective date of termination, Telcordia shall take
all commercially reasonable steps to wind-down the work in progress by the
effective date of such termination based on Telcordia's reasonable and good
faith understanding of the work NAPA would like to continue during such
wind-down period. Upon such termination, NAPA shall pay to Telcordia the
following: (i) fees for Services rendered and Deliverables provided by Telcordia
as of the effective date of termination; (ii) long-term operating and/or capital
fees incurred by Telcordia, prior to the effective date of termination, provided
that such fees were authorized by NAPA in the affected Work Statement(s) or
otherwise approved in writing and to the extent such fees have not been
previously recovered from NAPA by Telcordia; (iii) packaging, shipping and
similar costs of any equipment or materials required to be returned by Telcordia
to NAPA or Third Party vendors; (iv) vendor and subcontractor termination fees
that have been incurred in accordance with vendor contracts and other reasonable
and customary vendor and subcontractor termination fees provided that such fees
were authorized by NAPA in the affected Work Statement(s) or otherwise approved
in writing; and (v) such other reasonable expenses as may be agreed to by the
parties in writing. Effective upon such termination for convenience, Telcordia
shall have no further obligations or liability of any kind with respect to any
Deliverables or Services provided prior to termination under the terminated Work
Statement all of which shall be deemed provided on an "as is basis, except that
those Deliverables which have been accepted and paid for prior to termination or
upon termination under this Section shall be entitled to the applicable
warranties provided for such Deliverables set forth in this Agreement.

                                       2
<PAGE>
Telcordia may not terminate this Agreement or any Work Statement under this
Agreement, except as provided in this Section 9, or as otherwise agreed upon in
a specific Work Statement."

This amendment shall be effective when signed by the last party and shall
continue until the termination of the Agreement. All of the terms and conditions
of the Agreement, shall remain in full force and effect. This amendment is
incorporated by reference into the Agreement. Each party represents that this
amendment has been signed by their duly authorized representatives.

                            SCOPE CHANGE CONTROL FORM

This Scope Change No. 2 ("Scope Change') amends the Master Agreement, as
previously amended, Contract No. 20000822JS113827, ("Agreement") between NAP of
the Americas, Inc. ("NAPA"), a wholly owned subsidiary of Terremark Worldwide,
Inc. ("Terremark"), and Telcordia Technologies, Inc. ("Telcordia"), and is
effective as of this 30th day of June, 2000 ("Scope Change"). This Scope Change
incorporates all the terms and conditions of the Agreement except as may be
otherwise modified herein for the limited purpose set forth herein.

         1.       Title of Scope Change: NAPA Payments

         2.       Date of Scope Change: June 30 , 2001

         3.       Originator of Scope Change:             Max Figueroa

         4.       Reason for the Scope  Change:  The parties have agreed to
                  modify billing and payment terms to accommodate new Work
                  Statements.

         5.       Details of the Scope Change (including any specifications): NA

         6.       Implementation timetable of the Scope Change:

The Telcordia Program Office shall provide NAPA with an updated report for
actual outstanding unpaid calculated amounts ("Outstanding Amounts Report") on a
bi-monthly basis (twice per month) which will include the actual fees and
expenses incurred by NAPA for Work Statements executed before May 31, 2001, and
after May 31, 2001. The Telcordia Program Office has also generated a projected
NAPA expense obligation report ("Projected Expense Report") which includes the
estimated fees and expenses for Work Statements executed through May 31, 2001,
including Work Statements 1 through 10 (Attachment A). The parties agree that
the amounts detailed in the Outstanding Amounts Report, Attachment B, shall not
exceed the dollar amounts listed for the corresponding period in the Projected
Expense Report, Attachment A, and that NAPA shall provide payments to Telcordia
to reduce the amounts in the Outstanding Amounts Report to be less than or equal
to the corresponding amounts in Attachment A as described in this amendment.
Based on the Outstanding Amounts Report, Telcordia shall indicate to NAPA when
an additional payment is due, if any, and provide NAPA with written notice
regarding the amount of any necessary payments. NAPA shall pay any amounts
exceeding those listed in the Projected Expense Report (Attachment A) down to a
value equal to or less than the value for the corresponding period. Such payment
will be applied to the oldest outstanding invoice due by NAPA to Telcordia. If
there is a discrepancy between the actual invoice amount and calculated amount
provided to NAPA by the Program Office, the discrepancy will be reconciled in
the next Outstanding Amounts Report.

It is expected that any Telcordia request for an additional payment will be a
payment for a portion of the total outstanding calculated amount due to
Telcordia. NAPA shall pay the amount detailed in the notice via wire transfer
within three (3) business days of receipt of such notice. If NAPA fails to pay
the amount stated in the notice in full within three (3) business days after
receipt or otherwise is in arrears on other payments due to Telcordia, Telcordia
reserves the right to immediately stop work on any Work Statements executed
after May 31, 2001 with no further obligation to NAPA to continue or complete
such Work Statements. Notwithstanding anything stated above, NAPA is required to
continue to make regular payments on all invoices in
<PAGE>

accordance with the terms of the Master Agreement, as amended. In addition, all
future Work Statements executed between the parties will be paid in accordance
with the terms of the Master Agreement, as amended,(as were WS 1 through WS 10),
except that all WS will be subject to the terms of this agreement.

         7.       Additional fees or refund, if any, of the Scope Change: NA

         8.       Impact of the Scope Change on other aspects of the Schedule,
                  including but not limited to, the overall payment schedule,
                  contractual provisions, and Deliverable schedules: NA

         9.       Other Comments:               NA

The parties to this Scope Change agree to the terms of the Agreement, as amended
and further represent that this Scope Change is executed by their respective
authorized representatives in accordance with each parties' established
corporate policy. The parties to this Scope Change further agree that any terms
and conditions of the Agreement, as amended and not modified hereby shall remain
unchanged and in full force and effect.

<PAGE>

To support the deployment of the Interim NAP, Telcordia shall provide the
following Services:

      -- Telcordia shall provide Telcordia Provided Hardware and Software. The
         initial deployment of the Interim NAP is estimated to occur in December
         2000 and contain approximately fifty (50) peering connections. Any
         Hardware and Software required to support expansion beyond fifty (50)
         peering connections will be provided by NAPA at its sole expense.

      -- Telcordia shall ship, at NAPA's expense, Telcordia Provided Hardware
         and Software to the Interim NAP site in Miami, Florida.

      -- Telcordia shall provide, for the monthly rental fee set forth below,
         the Telcordia Provided Hardware and Software for NAPAs use in the
         Interim NAP. At the end of the rental period, Telcordia shall ship, at
         NAPAs expense, Telcordia Provided Hardware and Software to Telcordia's
         facilities in New Jersey.

      -- To support the operation of the Interim NAP beyond the Telcordia
         Provided Hardware and Software, which will support up to fifty (50)
         peering connections, Telcordia shall provide a Quarterly Bill of
         Materials which will contain Telcordia's proposed Hardware and Software
         requirements for the operation of the Interim NAP. It is estimated that
         two (2) Bill of Materials will be provided by Telcordia for the
         operation of the Interim NAP, one (1) Initial Bill of Materials to
         support the operation of the Interim NAP during the first quarter of
         2001 and one (1) Quarterly Bill of Materials to support the operation
         of the Interim NAP during the second quarter of 200l. [

      -- Telcordia shall coordinate with the equipment vendors regarding the
         delivery schedule the accuracy of Hardware and Software shipments.

      -- Telcordia shall arrange for the necessary support from the selected
         Hardware and Software manufacturers to support the installation,
         configuration, troubleshooting and upgrading of the NAP network. NAPA
         is responsible for the cost of support services from the vendors as
         part of the procurement process, which support is expected to be paid
         for by NAPA as part of the procurement of Hardware and Software, except
         for those support services associated with Telcordia Provided Hardware
         and Software, which are Telcordia's responsibility.

      o  To support the operation of the Permanent NAP, Telcordia shall provide
         the following Services:

      -- Telcordia shall provide a Quarterly Bill of Materials describing the
         Hardware and Software that Telcordia recommends for deployment in the
         Permanent NAP during the three (3) month term of the Quarterly Bill of
         Materials. The Quarterly Bill of Materials shall be substantially in
         the form illustrated in Exhibit A and should include information such
         as the justification for the expected Hardware and Software

                                       3
<PAGE>

         requirements, an identification of the Hardware and Software components
         recommended by Telcordia and an estimate of Telcordia' s price of the
         proposed Hardware and Software components, which shall be no more than
         15% above Telcordia's cost. It is estimated that the justification of
         the proposed Hardware and Software components will be based upon a set
         of business metrics jointly developed and agreed upon by Telcordia and
         NAPA. An example of such business metrics is the forecasted customer
         volume expected in the Permanent NAP during the three (3) month term of
         the Quarterly Bill of Materials.

6.       FEES AND PAYMENTS

NAPA shall pay Telcordia on the basis of (i) a time and materials estimate for
the Services, and (ii) a monthly rental fee for the Telcordia Provided Hardware
and Software as described below. The fees will be calculated as follows:

a)       ESTIMATED FEES: NAPA shall pay Telcordia the following fees:

         1)       ESTIMATED AMOUNTS: Telcordia estimates that the time &
                  materials fee for the Services set forth in SECTION 3 will be
                  approximately Two Hundred Eighty Two Thousand Dollars
                  ($282,000), excluding out of pocket expenses and materials.
                  This estimate is not binding. Telcordia shall notify NAPA when
                  it reaches eighty-five percent (85%) of the Estimated Fee.
                  Telcordia shall obtain prior written approval to exceed the
                  Estimated. Telcordia reserves the right to suspend the
                  performance of Services hereunder and toll the term of this WS
                  until NAPA approves in writing a revised Estimated Fee, if
                  any.

         2)       TELCORDIA PROVIDED HARDWARE AND SOFTWARE RENTAL FEE AMOUNTS:
                  The monthly rental fee for the Telcordia Provided Hardware and
                  Software is Thirty Six Thousand Three Hundred Thirty Three
                  Dollars (US$36,333). This fee is only relevant to Telcordia
                  Provided Hardware and Software. During the operation of the
                  Interim NAP, the Telcordia Provided Hardware and Software
                  shall be available to NAPA at a monthly rental fee of Thirty
                  Six Thousand Three Hundred Thirty Three Dollars (US$36,333).
                  NAPA shall have the right to use the Telcordia Provided
                  Hardware and Software from the date of delivery until the
                  operation of the Interim NAP is terminated, not to exceed a
                  twelve (12) month period, or unless otherwise terminated
                  earlier pursuant to the terms of this WS or by operation of
                  law.

         1)       HARDWARE AND SOFTWARE: NAPA further acknowledges that
                  Telcordia HAS NOT MADE, AND DOES NOT MAKE, ANY WARRANTY OR
                  REPRESENTATION, EITHER EXPRESSED OR IMPLIED, OR ANY KIND
                  WHATSOEVER WITH RESPECT TO THE HARDWARE OR SOFTWARE ACQUIRED
                  BY NAPA OR PROVIDED BY TELCORDIA FOR USE BY NAPA UNDER THIS
                  WS, INCLUDING BUT NOT LIMITED TO: (1) AS TO THE FITNESS,
                  DESIGN, OR CONDITION OF THE HARDWARE; (2) AS TO THE
                  MERCHANTABILITY OF THE HARDWARE OR ITS FITNESS FOR ANY
                  PARTICULAR PURPOSE; (3) as to the quality or capacity of the
                  Hardware or Software, the materials in the Hardware or
                  Software, or workmanship in the Hardware or Software; (4) as
                  to any latent defects in the Hardware or Software; (5) as to
                  any patent infringement; and (6) as to the compliance of the
                  Hardware or Software with any requirements of any law, rule,
                  specification, or contract pertaining thereto.

         2)       SOURCE. With regard to Hardware and Software not provided by
                  Telcordia, NAPA acknowledges that NAPA has selected both (a)
                  the Hardware and Software listed in the Quarterly Bill of

                                       9
<PAGE>

                  Materials; and (b) if applicable, the supplier named in the
                  Quarterly Bill of Materials from whom the Hardware and
                  Software is to be procured by NAPA. In this respect, NAPA
                  acknowledges that Telcordia is not the manufacturer of the
                  Hardware or publisher of the Software nor the agent of such
                  manufacturer or publisher.

         3)       PROBLEMS WITH HARDWARE OR SOFTWARE. If the Hardware or
                  Software is not properly installed, does not operate as
                  represented or warranted by the manufacturer, publisher or the
                  supplier or is unsatisfactory for any reason, NAPA shall make
                  a claim on account thereof solely against the supplier,
                  publisher or manufacturer and shall, nevertheless, pay
                  Telcordia all fees payable hereunder. As between NAPA and
                  Telcordia, and only in those instances where the manufacturer,
                  publisher or supplier has provided any maintenance agreement,
                  warranty or guaranty of any nature whatsoever applicable to
                  the Hardware or Software, Telcordia hereby assigns to NAPA
                  whatever assignable interest Telcordia may have in such
                  maintenance agreement, warranty or guaranty. The aforesaid
                  assignment shall not in any way be deemed to limit, negate, or
                  otherwise affect the disclaimer of warranties contained in the
                  preceding paragraphs, and Telcordia shall not incur any duties
                  arising out of any manufacturer's, supplier's or publisher's
                  warranties or guarantees, except as otherwise expressly set
                  forth herein. Further, Telcordia shall not incur any liability
                  whatsoever arising out of any breach of any manufacturer's,
                  supplier's or publisher's warranties or guarantees applicable
                  to the Hardware or Software.

         4)       DELIVERY AND INSPECTION. NAPA will accept the Telcordia
                  Provided Hardware and Software provided by Telcordia upon its
                  delivery to the Interim NAP.

         5)       REPAIRS; USE; ALTERATIONS. Telcordia, at Telcordia's expense,
                  shall keep the Telcordia Provided Hardware and Software in
                  good working condition and shall repair and furnish all labor,
                  parts, mechanisms, and devices required therefor. If at any
                  time Telcordia is not longer providing the labor and/or
                  services for operating the NAP, NAPA shall use such Telcordia
                  Provided Hardware and Software in a careful and lawful manner,
                  nor shall NAPA make any alterations, additions, or
                  improvements to such Telcordia Provided Hardware and Software
                  without Telcordia's prior written consent. All additions,
                  repairs, replacement parts, accessories, or improvements made
                  to such Telcordia Provided Hardware and Software, if removed
                  by any third party other than Telcordia, shall not be removed
                  without Telcordia's prior written consent.

         6)       LOSS OR DAMAGE. NAPA shall bear the entire risk of loss,
                  theft, destruction, or damage of the Hardware provided by
                  Telcordia or any portion thereof from any cause whatsoever. If
                  any such Hardware is totally destroyed, the liability of NAPA

                                       10
<PAGE>

                  to pay rent therefor may be discharged by paying Telcordia all
                  the rent due and to become due thereon, less the net amount of
                  the recovery, if any, actually received by Telcordia from
                  insurance or otherwise for such loss or damage. Except as
                  provided in the preceding sentence, the total or partial
                  destruction of any such Hardware, or total or partial loss of
                  use or possession thereof by NAPA, shall not release or
                  relieve NAPA from the duty to pay the usage fees herein
                  provided. Telcordia shall not be obligated to undertake, by
                  litigation or otherwise, the collection of any claim against
                  any person for loss or damage of such Hardware.

         7)       INSURANCE. NAPA shall, at NAPA'S own expense, insure the
                  Hardware provided by Telcordia at all times against all
                  hazards as requested by Telcordia, including but not limited
                  to theft, fire, flood or other catastrophe, and extended
                  coverage insurance, and such policies shall be payable to
                  Telcordia as Telcordia's interest may appear. This insurance
                  shall be reasonably satisfactory to Telcordia as to form,
                  amount, and insurer, and shall provide for at least ten (10)
                  days written notice of cancellation to Telcordia. Such
                  insurance policies or certificates thereof shall be delivered
                  by NAPA to Telcordia before Telcordia will be required to
                  deliver such Hardware and Software to NAPA. In addition, NAPA
                  shall, at NAPA's own expense, carry occurrence-type public
                  liability insurance with respect to such Hardware and the use
                  thereof in such amounts and with such insurers as are
                  reasonably satisfactory to Telcordia, and such insurance
                  policies or certificates thereof shall also name Telcordia as
                  an insured and loss payee thereunder.

         8)       NAPA'S TAX AND LIEN OBLIGATION. NAPA shall keep the Hardware
                  provided by Telcordia free and clear of all levies, liens, and
                  encumbrances. NAPA shall, in the manner directed by Telcordia:
                  (a) make and file all declarations and returns in connection
                  with all charges and taxes (local, state, and federal), which
                  may now or hereafter be imposed upon or measured by the
                  ownership, leasing, rental, sale, purchase, possession, or use
                  of such Hardware, excluding, however, all taxes on or measured
                  by Telcordia's net income; and (b) pay all such charges and
                  taxes. In the event that Telcordia shall elect to make and
                  file any or all declarations and returns in connection with
                  such charges and taxes to pay them, then NAPA shall reimburse
                  Telcordia, upon demand of Telcordia, for any and all such
                  charges and taxes applicable to such Hardware herein provided
                  by Telcordia to NAPA.

         9)       ULTIMATE TAX AND LIEN RESPONSIBILITY. Telcordia's good faith
                  acceptance of a tax exemption certificate does not represent
                  an assurance that the State will also accept the certificate
                  as valid at the time of audit review. NAPA is responsible for
                  any future audit adjustment if the certificate is not
                  accepted. NAPA agrees to reimburse Telcordia for the amount of
                  audit adjustment and the aggregate of tax, interest, and
                  penalty, if a certificate is subsequently denied.

         10).     TELCORDIA'S PERFORMANCE OF NAPA'S OBLIGATIONS. If NAPA fails
                  to duly and properly perform any of its obligations under this
                  WS with respect to the Hardware provided by Telcordia,
                  Telcordia may (at Telcordia's option) perform any act or make
                  any payment which Telcordia deems necessary for the
                  maintenance and preservation of such Hardware and Telcordia's
                  title thereto, including payment for satisfaction of liens,
                  repairs, taxes, levies, and insurance, and all sums so paid or
                  incurred by Telcordia, together with interest, and any
                  reasonable legal fees incurred by Telcordia in connection
                  therewith, shall be additional rent under this WS and payable
                  by NAPA to Telcordia on demand. The performance of any act or
                  payment by Telcordia as aforesaid shall not be deemed a waiver
                  or release of any obligation or default on the part of NAPA.

         11)      INDEMNITY. Except for the negligence or willful misconduct of
                  Telcordia related to the Services provided in this section
                  and/or any other related Work Statement, (i) NAPA assumes the
                  risk of liability arising from or pertaining to the
                  possession, operation, or use of the Hardware provided by
                  Telcordia; and (ii) NAPA hereby agrees to defend, indemnify
                  and hold Telcordia harmless from and against any and all
                  claims, costs, expenses, damages, and liabilities arising from
                  or pertaining to the use, possession, or operation of such
                  Hardware.

         12)      TELCORDIA'S CONSENT TO OFFSET. Without Telcordia's prior
                  written consent, NAPA shall not (a) assign, transfer, pledge,
                  hypothecate, or otherwise dispose of this WS, the Hardware
                  provided by Telcordia, or any interest therein; or (b) sublet
                  or lend such Hardware or permit it to be used by anyone other
                  than NAPA or NAPA's employees.

         13)      TELCORDIA'S ASSIGNMENT. Telcordia may assign this WS and/or
                  mortgage the Hardware provided by Telcordia, in whole or in
                  part, without notice to NAPA, however, if NAPA is given notice
                  of such assignment, NAPA agrees to acknowledge receipt thereof
                  in writing. Each such assignee and/or mortgagee shall have all
                  of the rights, but none of the obligations of Telcordia under
                  this WS. NAPA shall not assert against assignee and/or
                  mortgagee any defense, counterclaim, or offset that NAPA may
                  have against Telcordia. Notwithstanding any such assignment,
                  Telcordia warrants that NAPA shall quietly enjoy use of such
                  Hardware subject to the terms and conditions of this WS.
                  Subject to the foregoing, this WS inures to the benefit of and
                  is binding upon the heirs, legatees, personal representatives,
                  successors, and assigns of the parties hereto.

         14)      DEFAULT. If NAPA fails to pay when due any rental payment or
                  other amount required herein to be paid by NAPA, or if NAPA
                  makes an assignment for the benefit of creditors, whether
                  voluntary or involuntary, or if NAPA shall make a bulk
                  transfer of any of NAPA'S assets, or if NAPA discontinues
                  NAPA's normal business operation for a period of ten (10) days
                  or more, or if a petition is filed by or against NAPA under
                  the bankruptcy laws of the United States, Telcordia shall have

                                       12
<PAGE>

                  the right to exercise any one or more of the following
                  remedies in order to protect the interest and reasonably
                  expected profits and bargains of Telcordia:

                  A.       Telcordia may recover from NAPA all rental payments
                           and other amounts then due and as they shall
                           thereafter become due hereunder;

                  B.       Telcordia may take possession of any or all items of
                           the Telcordia Provided Hardware and Software,
                           wherever these items may be located, without demand
                           or notice, without any court order or other process
                           of law, and without liability to NAPA for any damages
                           occasioned by such taking or possession, and in
                           removing all such Hardware, Telcordia may, if
                           permitted by law, use any of NAPA's licenses in
                           respect to all such Hardware (any such taking or
                           possession shall not constitute a termination of this
                           WS);

                  C.       Telcordia may recover from NAPA, with respect to any
                           and all items of such Hardware and Software that had
                           been used and maintained as provided in this WS,
                           provided, however, that upon repossession or
                           surrender of such Hardware and Software, Telcordia
                           shall sell, lease, or otherwise dispose of such
                           Hardware in a commercially reasonable manner with or
                           without notice, on public or private bid, at
                           Telcordia's place of business as indicated in this
                           WS, or at such other place as Telcordia shall
                           determine, and apply the net proceeds thereof (after
                           deducting all expenses, including attorneys fees,
                           incurred in connection therewith) to the sum of
                           monies due to Telcordia hereunder.

                  D.       Telcordia may pursue any other remedy at law or in
                           equity.

         15)      OTHER DEFAULTS. If NAPA fails to perform any of the provisions
                  under this WS or any other agreement with Telcordia, or if
                  NAPA makes a bulk transfer of furniture, furnishings,
                  fixtures, or other equipment or inventory, Telcordia shall
                  have the right to exercise any remedy available at law or in
                  equity, including but not limited to seeking damages or
                  specific performance {and/or} obtaining an injunction.

         16)      CUMULATIVE RIGHTS. No rights or remedy herein conferred upon
                  or reserved to Telcordia is exclusive of any right or remedy
                  herein or by law or equity provided or permitted, but each
                  shall be cumulative of every other right or remedy given
                  hereunder or now or hereafter existing at law or in equity or
                  by statute or otherwise, and may be enforced concurrently
                  therewith or from time to time, but Telcordia shall not be

                                       13
<PAGE>

                  entitled to recover a greater amount in damages than Telcordia
                  could have gained by receipt of NAPA's full, timely, and
                  complete performance of NAPA's obligations pursuant to the
                  terms of this WS plus accrued expenses and interest.

The parties to this WS agree to the terms of the Master Agreement, as amended
and this WS and further represent that this WS is executed by duly authorized

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

This Work Statement ("WS") is issued under the Master Agreement dated November
16, 2000 ("Master Agreement") between NAP of the Americas, Inc. ("NAPA"), a
wholly owned subsidiary of Terremark Worldwide, Inc. ("Terremark") and Telcordia
Technologies, Inc. ("Telcordia"). Telcordia shall provide the following Services
under the terms and conditions of the Master Agreement and any additional terms
contained in this WS.

SCOPE OF SERVICES

As described in this WS, Telcordia shall provide Professional Services
associated with developing the Market Strategy and Business Operations Design
("Services") which will establish and manage the NAP of the Americas in Miami.
In the balance of this document, "Telcordia" shall be understood to mean
activities performed by either Telcordia or its parent company, SAIC, or both.

This WS will outline the Services Telcordia shall provide related to the market
strategy and business operations involved in the formation of the NAPA. These
Services shall include:

o        Market Strategy and Services Development

o        Tactical Marketing Development

o        Process Development

o        Financial Modeling

1.       DESCRIPTION OF SERVICES

Telcordia shall perform the following activities:

A.       MARKET STRATEGY AND SERVICES DEVELOPMENT

In order to begin offering basic services to the customers of the NAP of the
Americas ("NAP Customers"), assumptions have been made as to the initial core
services that would meet NAP Customers' needs. The following core services have
been identified and will be offered initially. In support of this planning
assumption, market strategy and additional service definition work will be
undertaken, as outlined herein.

The core basic services that will initially be offered to NAP Customers are:

o        Basic Public Peering Services which provides a connection to the NAP
         network supporting public peering and route arbitration services.

<PAGE>

o        Basic Private Peering Services which provides a connection between NAP
         Customers.

o        Basic Collocation Services which provides for the rental of space
         within the NAP facility.

o        Equipment Monitoring which provides for the monitoring of the customer
         equipment in the co-location space.

Building on these core services, the business analysis work proposed herein for
the NAP of the Americas will provide recommendations on services, features and
pricing. Leveraging market research, Telcordia and Terremark will jointly
identify value added services which are most likely to meet the needs of the NAP
of the Americas. These services will be rank ordered and evaluated in
conjunction with Terremark. Potential prices, mix of services and services
partners will be determined on an as needed basis. The Deliverables from this
part of the project consist of an analysis of demand, pricing and competitors,
resulting in a short-term market strategy.

Telcordia shall define and evaluate two (2) to three (3) alternative service
models (wholesale, retail or a combination of wholesale/retail) for the
Permanent NAP, with the goal of optimizing the balance among several key
variables, for example, the value proposition for potential customers and the
pros and cons of providing different services either directly by the NAP or
indirectly, through partnerships, alliances or resale arrangements. The analysis
shall consist of:

o        With concurrence of Terremark, analysis of up to five (5) potential
         customer types in order to identify their preferred service needs and
         the service characteristics that present an attractive value
         proposition for them. The customer types will consist of global and
         regional carriers, Internet service providers ("ISPs"), and possibly
         intermediaries such as web hosting and application hosting companies or
         enterprise customers.

o        Analysis of service offerings that are available today from up to ten
         (10) competitors. In addition, the analysis will include future
         services that may be expected in the future based on competitors'
         current announcements about their investments and their business
         partnerships/alliances.

o        Identification and analysis of services to be offered at the NAP with a
         time line and cost benefit analysis taking account of the
         infrastructure and software systems required to support these services.

o        A composite analysis of services mapped to customer segments taking
         account of competitors' behavior.

o        Value added service descriptions for NAP Services.

Telcordia shall assist in developing a market strategy for a set of primary and
ancillary services that may be provided directly at the NAP, remotely, or that
may be provided to intermediaries for their customers. This aspect of this WS
will be to develop primary and ancillary services that will potentially be
offered at the Interim NAP and those offered at the Permanent NAP.

Telcordia shall perform the following activities, organized in two phases:

                                       2
<PAGE>

PHASE 1: SHORT-TERM MARKET STRATEGY FOR THE CORE/PRIMARY SERVICES

o        Identify the primary connectivity services and estimate the traffic
         levels necessary for the NAP to get started.

o        Create an analytical framework for the market strategy with NAP
         services defined at different levels of functionality from simple
         interconnection to all the state-of-the-art capabilities and features
         needed to attract multiple backbone providers to combine their public
         and private peering at NAP of the Americas.

o        Develop the dimensions of the competition the NAP of the Americas faces
         from other players.

o        Create preliminary value propositions for the different types of
         potential NAP of the Americas customers, such as carriers & service
         providers (IXCs, ISPs, CLECs, web-hosting companies and ASPs). This
         will involve a mapping of potential customers to the services they
         value and analysis of benefits of NAP of the Americas relative to their
         current suppliers.

o        Create a mapping from potential clients to likely traffic levels for
         attracting "anchor tenants" and other tenants.

PHASE 2: MID-TERM MARKET STRATEGY

It is assumed that a carrier-neutral strategy for NAP of the Americas will be
adopted to create an infrastructure that will enable the NAP Miami users to
provide different value-added services, such as web hosting, caching, content
delivery, storage, voice over IP, etc., to their customers. Careful
consideration will be given to the NAPA to ensure that it is complimentary to
and not unnecessarily competitive with its customer base.

The mid-term market strategy analysis will include an evaluation of potential
services, functionality and competitor's services and models. The preliminary
analysis of value propositions from Phase 1 will be completed in Phase 2 to
determine the additional services and functionality needed for NAP of the
Americas to attract different types of potential customers considering the
opportunities to leverage early commitments of the customer base and the key
risk factors. This work will consider business models for neutral services that
can be provided directly to tenants of the NAP, such as, share hands, network
security, network back up and storage, web hosting, caching, performance
monitoring and reporting, etc. The work activities will be as follows:

o        Validate the belief that interconnection at NAP of the Americas can
         generate significant savings in transport cost for regional carriers
         and ISPs. Identify functionality requirements of web
         hosting/co-location companies.

o        Identify functionality requirement for enterprise customers.

                                       3
<PAGE>

o        Identify additional functionality such as higher levels of reliability,
         security, scalability and customer care required for NAP of the
         Americas to differentiate itself from interconnection service providers
         like Equinix. InterNAP, Savvis, SDFC and Colo.com.

o        Analyze value-added services for example, caching, security, storage
         and disaster recovery services.

o        Analyze the content delivery service business and incentives required
         to attract Hispanic-focused ISPs to the NAP of the Americas.

o        Analyze new service offerings announced by competitors on an on-going
         basis.

o        Analyze likely future offerings based on competitors' announcements
         about their investments and their business partnerships/alliances.

o        Identify managed services and third-party providers that can deploy in
         partnership or reseller arrangements with Terremark.

o        Develop recommendations regarding business partnerships/revenue-sharing
         arrangements with Best-of-Breed players for the NAP of the Americas to
         differentiate its value-added service offerings.

o        Review the capabilities of the supporting NAP of the Americas
         operations infrastructure and network operations center to determine if
         these internal support mechanisms could be leveraged to provide
         external value added services. For example, on going monitoring
         services for third party equipment.

B.       TACTICAL MARKETING DEVELOPMENT

Telcordia shall assist NAP of the Americas with their marketing efforts in
supplying on-going technical resources that will be available to the sales force
to assist with market development, product planning, presentation preparation,
customer meetings, customer inquiries and technical sales support for the
duration of this work statement.

C.       PROCESS DEVELOPMENT

Telcordia shall develop and document process flows for the Marketing and Sales
Process and shall coordinate interface points with the processes being handled
via the BSS/OSS Service Bureau in San Diego. These interface points will be
designed and documented to facilitate flow-through of customer orders throughout
all of the critical business processes at a high level (service activation and
provisioning, service assurance and maintenance and customer care and billing).
It is assumed that these critical processes will be managed at the BSS/OSS
Service Bureau in San Diego.

Telcordia process consultants shall also work with appropriate NAPA staff to
review and approve all of the processes that will be utilized at the BSS/OSS
Service Bureau in San Diego. Telcordia process consultants shall also evaluate
the documented processes and identify any business processes that may not be

                                       4
<PAGE>

fully developed and/or adequately documented. Telcordia shall produce a report
of these gaps and develop a plan to close any process gaps identified. Telcordia
shall implement this plan to close any identified process gaps.

D.       FINANCIAL MODELING

Telcordia, in conjunction with the Market Strategy consultants, shall conduct
analyses to determine the expected cash flow for NAPA. Inputs to the financial
analysis are described below. The result will be a financial analysis
encompassing discounted cash flow, expected payback period and rate of return
for the given strategic direction over a three to five year planning period.

1.       Revenue Projections: Telcordia shall work with NAPA to develop
         projections for the potential revenues associated with each service

         portfolio and other economic factors will be used as input to these
         revenue projections.

2.       Investment Projections: Telcordia shall work with NAPA or other
         appropriate resources to determine the investments required to support
         the services.

3.       Expense Projections: Telcordia will work with NAPA or other appropriate
         resources to develop the network and operational expenses that can be
         expected in support of these services.

4.       Sensitivity Analysis: Telcordia shall develop a sensitivity analysis to
         assess the critical factors driving the value of the opportunity and
         impacts of uncertainties.

6.       FEES AND PAYMENTS

NAPA shall pay Telcordia for the Services on a time and materials and fee for
service basis as follows:

         1)       ESTIMATED AMOUNTS: Telcordia estimates that the Time and
                  Material fee for the Services detailed in Section 2.4 of this
                  WS shall be approximately $520,000, excluding out of pocket
                  expenses and materials. This estimate is not binding.
                  Telcordia shall notify NAPA when it reaches eighty-five
                  percent (85%) of the Estimated Fee. Telcordia shall obtain
                  prior written approval to exceed the Estimated Fee. Telcordia
                  reserves the right to suspend the performance of Services
                  hereunder and toll the term of this WS until NAPA approves in
                  writing a revised Estimated Fee, if any.

         2)       FIXED FEE: The fixed fee for Rapid Apps(TM) Service Bureau
                  operations detailed in Sections 2.1, 2.2 and 2.3 of this WS
                  shall total $340,000. Service Center fees are based on the
                  assumptions in Section 5 of this WS for the projected activity
                  in the interim NAP facility. The total Service Center fees for
                  the duration of this WS are $340,000. This is a fixed price.
                  This pricing is based on not exceeding the projected activity
                  assumptions of paragraph 5. If ramp up and operations volume
                  exceeds the projected activity assumptions of paragraph 5, we
                  will revisit the fixed fee for Service Bureau operations.

any additional terms contained in this WS.

1. SCOPE OF SERVICES

As described in this WS, Telcordia shall provide Professional Services
associated with the planning, design, and installation of a permanent Internet
Network Access Point ("PNAP") network at the Technology Center of the Americas
("TECOTA") location in Miami. Telcordia shall architect, design and deploy the
PNAP as described in this WS. Telcordia shall also design, and deploy a primary
on-site Network Operations Center ("NOC") for the PNAP. Backup network
operations activities will be accomplished at an off-site location and covered
in a separate WS. All operational activities will be covered in a separate Work
Statement. In the balance of this document, references to Telcordia activities
shall be understood to mean activities performed by either Telcordia, SAIC, or
both.

Telcordia shall provide the following Professional Services ("Services") to
NAPA:

         o        Update the existing design of the NAP, plan and develop a
                  prototype network architecture at Telcordia laboratories in
                  Red Bank, NJ to support the initial testing of the NAP
                  network;

         o        Update the existing design for the NAP network and operations
                  environment and deploy an operations environment that is
                  suitable for the PNAP;

         o        Configure and test of the NAP network for a limited number of
                  initial customers.

2. DESCRIPTION OF SERVICES

PNAP Network Architecture, Design and Deployment Support

Telcordia shall perform the following activities:

         (a)      NAP ARCHITECTURE: Telcordia shall update a network
                  architecture for the PNAP. This architecture will allow for
                  the extension of services from the Interim NAP site to the
                  PNAP site. The architecture will also support a higher traffic
                  volume than is currently available with any of the four

<PAGE>

                  competitive Tier 1 NAPs. This architecture will determine how
                  advanced services will be supported, (e.g., optical routing).
                  In addition, the architecture will support the ability to
                  provide services off-site in order to allow a simple expansion
                  to other nearby locations. The network architecture will
                  include a technical description of how private and public
                  peering functions will be supported, aspects of Internet
                  Protocol ("IP") routing connectivity including the IP address
                  plan and other capabilities of the PNAP.

         (b)      EQUIPMENT SELECTION: Telcordia shall evaluate the existing
                  network equipment products for use in the PNAP. If Telcordia
                  determines that there are some technical issues with vendor
                  equipment that cannot be resolved with the vendor
                  documentation, Telcordia shall conduct a technical comparison
                  and assess the functionality of each product. The technical
                  comparison will involve Telcordia testing equipment from
                  multiple vendors, and providing a technical comparison of
                  their features and performance. Based on this technical
                  information, and non-technical information such as pricing and
                  availability, Telcordia shall recommend and NAPA shall select
                  the appropriate equipment for the PNAP.

         (c)      NAP DESIGN: Telcordia shall develop a network design for the
                  PNAP. This design shall include the description of the
                  specific equipment to be used in the PNAP, and how this
                  equipment is interconnected to customer equipment and the
                  network management equipment. The design shall be sufficient
                  to support the initial number of customers specified in the
                  PNAP financial model. The design will also include the
                  capability to expand the NAP to support the maximum number of
                  customers specified in the financial model.

         (d)      NETWORK MANAGEMENT ARCHITECTURE: Telcordia shall develop a
                  network management architecture that will describe how the
                  PNAP can be managed. This will include support for a primary
                  Network Operations Center ("NOC") that is co-located with the
                  PNA.P ("Miami NOC") and a backup off-site NOC. It will also
                  support mechanisms for managing the Interim NAP equipment.

                  o        Definition of roles of Primary and Second NOCs for
                           PNAP to achieve objectives of cost containment and
                           monitoring levels.

                  o        Agreement on Levels of Monitoring for NAP and
                           Co-location space (one level or tiered).

                  o        Level of Automation for Each of the Five Network
                           Management Areas (Fault, Configuration, Accounting,
                           Performance, and Security - FCAPS).

                  o        Identification of Systems/Vendors for each FCAPS
                           area.

                  o        Reusing the appropriate systems from the Interim NAP
                           implementation, and the identification of systems
                           that need to be developed.

                  o        Concurrence on phased rollout for each area under
                           FCAPS

                                       2
<PAGE>

                  o        Preliminary Systems Integration and Instrumentation.

         (e)      METHODS & PROCEDURES: Telcordia shall develop several methods
                  and procedures for the PNAP. These methods and procedures will
                  be designed to be used in the PNAP and will include:
                  provisioning a new customer, troubleshooting the Miami NOC and
                  the collection and storage of network information.

                  o        Goal will be to reuse as many of the M&P developed
                           for the Interim NAP as possible.

                  o        Assumption is that staff currently on Interim NAP
                           will move to the PNAP (i.e., skill set will be
                           comparable).

                  o        M&Ps will be available electronically on operator
                           consoles.

                  o        M&Ps will be electronically linked to particular
                           activities in FCAPS (e.g., an alarm presented under
                           Fault Management on an operator screen will cause a
                           pop-up of the relevant M&P (this is a target
                           capability and will not be delivered at the beginning
                           of General Availability).

         (f)      NETWORK MANAGEMENT DESIGN: Telcordia shall develop a design
                  for the Miami NOC-based network management system. This design
                  will include the hardware and software required to implement
                  the features described in the network management architecture.
                  It will not include the design of the off-site NOC.

                  o        As per the NM architecture in item d above, the
                           design of the NM systems will use world class
                           hardware and software and be integrated and initially
                           system tested at the Telcordia Red Bank location.
                           Possible software solutions include: platforms from
                           Computer Associates, Action Request System (i.e.,
                           Remedy for Trouble Ticketing), Tivoli, HP OpenView,
                           and NetCool.

                  o        Final instrumentation of the NM systems will occur at
                           the PNAP.

                  o        Following instrumentation, operator training will
                           commence, followed by an Operational Readiness Test
                           (ORT).

         (g)      TEST PLAN: Telcordia shall develop a PNAP Test Plan for the
                  NAP network. The Test Plan shall include the processes to be
                  used to verify that the PNAP network (i) provides the features
                  specified in the Network Architecture, (ii) can be managed as
                  specified in the network management plan.

         (h)      NAP DEPLOYMENT: Telcordia shall deploy the PNAP network as
                  described in the PNAP design document in the Miami TECOTA
                  facility. The purchase or financing of the equipment used in
                  the PNAP network is beyond the scope of this WS.

                            SCOPE CHANGE CONTROL FORM

This Scope Change No. 1NAP10-1 ("Scope Change") amends the Work Statement,
Contract No. 1NAP10, ("Work Statement") between NAP of the Americas, Inc.
("NAPA"), a wholly owned subsidiary of Terremark Worldwide, Inc. ("Terremark"),
and Telcordia Technologies, Inc. ("Telcordia"), and is effective as of this 27TH
day of March, 2001 ("Scope Change"). This Scope Change incorporates all the
terms and conditions of the Work Statement and Agreement except as may be
otherwise modified herein for the limited purpose set forth herein.

         1.       Title of Scope Change: Resale of Hardware for Permanent NAP in
                  Miami.

         2.       Date of Scope Change: March 28, 2001

         3.       Originator of Scope Change: Max Figueroa

         4.       Reason for the Scope Change: NAPA has requested that Telcordia
                  purchase hardware in support of the development of a Network
                  Operations Center (NOC) at the Permanent NAP facility in
                  Miami.

         5.       Details of the Scope Change (including any specifications):
                  Telcordia shall perform the following services:

                  o        Upon NAPA' s written approval of the quote for
                           hardware, and associated support contracts, contained
                           in Attachment A "Hardware", NAPA will issue a
                           Purchase Order to Telcordia for the full amount of
                           the hardware. Telcordia shall then order and take
                           delivery of such Hardware.

                  o        Upon completion of the development of the solution
                           using the Hardware as described in Work Statement
                           1NAP10, Telcordia shall ship, at NAPA's expense
                           including insurance coverage, the Hardware to a
                           secure location designated by NAPA in Miami. All
                           equipment will be considered accepted by NAPA upon
                           delivery to its designated destination.

                  o        In no event shall Telcordia have any liability in
                           connection with shipment, nor shall the carrier be
                           deemed to be an agent of Telcordia. Telcordia shall
                           not be liable for damage or penalty for delay in
                           delivery or for failure to give notice of any delay.

         6.       Implementation timetable of the Scope Change: Telcordia shall
                  place orders for Hardware by March 30, 2001.

         7.       Additional fees or refund, if any, of the Scope Change: NAPA
                  shall pay Telcordia for the Hardware on the basis of a fixed
                  price. Telcordia shall invoice NAPA for the entire amount due
                  upon signature of this change order by both parties. Telcordia
                  understands that NAPA is pursuing financing for the Hardware
                  but that such financing will not be completed before Telcordia
                  issues the purchase order. As a result, NAPA agrees to pay
                  Telcordia the full amount of $508,055.13 ("Advance Payment")
                  in advance of Telcordia's issuance of a purchase order for the
                  Hardware.

                  If NAPA is successful in closing financing with a leasing
                  company ("Leasing Company") for the Hardware within thirty
                  (30) days of the signature of this Change Order, and Telcordia
                  receives written evidence from such Leasing Company that
                  payment has been made to Sun Microsystems, Inc. ("Sun"), which

<PAGE>

                  is the Telcordia price per Attachment A ("Vendor Payment") for
                  the equipment within the same thirty (30) day period,
                  Telcordia will return to NAPA the Vendor Payment either as a
                  cash payment or a credit to the oldest outstanding invoice.
                  The form of return payment will be either a check or a credit
                  to NAPA, at NAPA's option, subject to the following: (1) If
                  NAPA has an outstanding debit balance with Telcordia, the
                  credit and/or check shall be reduced by the amount of the
                  debit balance and the debit balance will be satisfied first;
                  and (2) Telcordia shall retain the difference between the
                  Advance Payment and Vendor Payment in consideration for
                  Telcordia purchasing Hardware for resale to NAPA. Telcordia
                  shall also provide the Leasing Company with an assignment
                  letter assigning full right and title to the Hardware
                  purchased in satisfaction of all Telcordia obligations under
                  this agreement.

         8.       Impact of the Scope Change on other aspects of the Schedule,
                  including but not limited to, the overall payment schedule,
                  contractual provisions, and Deliverable schedules:

The following additional terms apply to the resale of hardware as described in
this change order.

                  o        TRANSFER OF TITLE: After payment in full is received
                           by Telcordia for the Hardware, Telcordia will ship
                           such items, at NAPA's expense including insurance
                           coverage, to a location designated by NAPA, no later
                           than thirty (30) calendar days after payment has been
                           received. Title to such Hardware obtained by
                           Telcordia for resale to NAPA shall pass to NAPA upon
                           receipt of the items so purchased.

                  o        HARDWARE AND SOFTWARE: NAPA further acknowledges that
                           Telcordia HAS NOT MADE, AND DOES NOT MAKE, ANY
                           WARRANTY OR REPRESENTATION, EITHER EXPRESSED OR
                           IMPLIED, OR ANY KIND WHATSOEVER WITH RESPECT TO THE
                           HARDWARE ACQUIRED BY NAPA UNDER THIS CHANGE ORDER,
                           INCLUDING BUT NOT LIMITED TO: (1) AS TO THE FITNESS,
                           DESIGN, OR CONDITION OF THE HARDWARE; (2) AS TO THE
                           MERCHANTABILITY OF THE HARDWARE OR ITS FITNESS FOR
                           ANY PARTICULAR PURPOSE; (3) as to the quality or
                           capacity of the Hardware , the materials in the
                           Hardware ,or workmanship in the Hardware; (4) as to
                           any latent defects in the Hardware; (5) as to any
                           patent infringement; and (6) as to the compliance of
                           the Hardware with any requirements of any law, rule,
                           specification, or contract pertaining thereto.

                  o        PROBLEMS WITH HARDWARE. If the Hardware is not
                           properly installed, does not operate as represented
                           or warranted by the manufacturer, publisher or the
                           supplier, NAPA shall make a claim on account thereof
                           solely against the supplier, publisher or
                           manufacturer and shall, nevertheless, pay Telcordia
                           all fees payable hereunder. As between NAPA and
                           Telcordia, and only in those instances where the
                           manufacturer, publisher or supplier has provided any
                           maintenance agreement, warranty or guaranty of any
                           nature whatsoever applicable to the Hardware,
                           Telcordia hereby assigns to NAPA whatever assignable

                                                                          Page 2
<PAGE>

                           interest Telcordia may have in such maintenance
                           agreement, warranty or guaranty. The aforesaid
                           assignment shall not in any way be deemed to limit,
                           negate, or otherwise affect the disclaimer of
                           warranties contained in the preceding paragraphs.
                           Telcordia shall not incur any duties arising out of
                           any manufacturer's, supplier's or publisher's
                           warranties or guarantees, except as otherwise
                           expressly set forth herein. Further, Telcordia shall
                           not incur any liability whatsoever arising out of any
                           claims by NAPA or breach of any manufacturer's,
                           supplier's or publisher's warranties or guarantees
                           applicable to the Hardware.

                  o        DELIVERY AND INSPECTION. NAPA will accept the
                           Hardware provided by Telcordia upon its delivery to
                           the Permanent NAP.

                  o        LOSS OR DAMAGE. Except for the negligence or willful
                           misconduct of Telcordia related to the Services
                           provided by Telcordia, NAPA shall bear the entire
                           risk of loss, theft, destruction, or damage of the
                           Hardware provided by Telcordia or any portion thereof
                           from any cause whatsoever. The total or partial
                           destruction of any such Hardware, or total or partial
                           loss of use or possession thereof by NAPA, shall not
                           release or relieve NAPA from the duty to pay the fees
                           herein provided. Telcordia shall not be obligated to
                           undertake, by litigation or otherwise, the collection
                           of any claim against any person for loss or damage of
                           such Hardware.

                  o        ULTIMATE TAX AND LIEN RESPONSIBILITY. Telcordia's
                           good faith acceptance of a tax exemption certificate
                           does not represent an assurance that the State will
                           also accept the certificate as valid at the time of
                           audit review. NAPA is responsible for any future
                           audit adjustment if the certificate is not accepted.
                           NAPA agrees to reimburse Telcordia for the amount of
                           audit adjustment and the aggregate of tax, interest,
                           and penalty, if a certificate is subsequently denied.

                  o        INDEMNITY. Except for the negligence or willful
                           misconduct of Telcordia related to the Services
                           provided in this section and/or any other related
                           Work Statement, (i) NAPA assumes the risk of
                           liability arising from or pertaining to the
                           possession, operation, or use of the Hardware; and
                           (ii) NAPA hereby agrees to defend, indemnify and hold
                           Telcordia harmless from and against any and all
                           claims, costs, expenses, damages, and liabilities
                           arising from or pertaining to the use, possession, or
                           operation of such Hardware.

PERFORMANCE FROM EXPERIENCE

                            SCOPE CHANGE CONTROL FORM

THIS Scope Change No. 1NAP10-2 ("Scope Change") amends the Work Statement,
Contract No. 1NAP10, ("Work Statement") between NAP of the Americas, Inc.
("NAPA"), a wholly owned subsidiary of Terremark Worldwide, Inc. ("Terremark"),
and Telcordia Technologies, Inc. ("Telcordia"), and is effective as of this 13
day of APRIL, 2001 ("Scope Change"). This Scope Change incorporates all the
terms and conditions of the Work Statement and Agreement except as may be
otherwise modified herein for the limited purpose set forth herein.

         1.       Title of Scope Change: Resale of Software for Permanent NAP in
                  Miami.

         2.       Date of Scope Change: April 13, 2001.

         3.       Originator of Scope Change: Max Figueroa.

         4.       Reason for the Scope Change: NAPA has requested that Telcordia
                  purchase software ("Software") and the associated professional
                  services provided by the designated software vendors outlined
                  in Attachment A, in support of the development of a Network
                  Operations Center (NOC) at the Permanent NAP facility in
                  Miami.

         5.       Details of the Scope Change (including any specifications):
                  Telcordia shall perform the following services:

                  o        Upon NAPA's approval of the quote for Software, and
                           associated support contracts, contained in Attachment
                           A, NAPA will issue a Purchase Order to Telcordia for
                           the full amount of the Software. Telcordia shall then
                           order and take delivery of such Software.

                  o        Upon completion of the development of the solution
                           using the Software as described in Work Statement
                           1NAP10, Telcordia shall ship, at NAPA's expense
                           including insurance coverage, the Software to a
                           secure location designated by NAPA in Miami. All
                           equipment and integrated Software will be considered
                           accepted by NAPA upon delivery to its designated
                           destination.

                  o        In no event shall Telcordia have any liability in
                           connection with shipment, nor shall the carrier be
                           deemed to be an agent of Telcordia. Telcordia shall
                           not be liable for damage or penalty for delay in
                           delivery or for failure to give notice of any delay.

                        CONFIDENTIAL -- RESTRICTED ACCESS

         6.       Implementation timetable of the Scope Change: Telcordia shall
                  place orders for the Software by April 13, 2001.

         7.       Additional fees or refund, if any, of the Scope Change: NAPA
                  shall pay Telcordia for the Software on the basis of a fixed
                  price. Telcordia shall invoice NAPA for the entire amount due
                  upon signature of this change order by both parties. Telcordia
                  understands that NAPA is pursuing financing for the Software,
                  but that such financing will not be completed before Telcordia
                  issues the purchase order. As a result, NAPA agrees to pay
                  Telcordia the full amount of $418,820.39 ("Advance Payment")
                  in advance of Telcordia's issuance of a purchase order for the
                  Software.

                  If NAPA is successful in closing financing with a leasing
                  company ("Leasing Company") for the Software within thirty
                  (30) days of the signature of this Change Order, and Telcordia

                           supplier, NAPA shall make a claim on account thereof
                           solely against the supplier, publisher or
                           manufacturer and shall, nevertheless, pay Telcordia
                           all fees payable hereunder. As between NAPA and
                           Telcordia, and only in those instances where the
                           manufacturer, publisher or supplier has provided any
                           maintenance agreement, warranty or guaranty of any
                           nature whatsoever applicable to the Software,
                           Telcordia hereby assigns to NAPA whatever assignable
                           interest Telcordia may have in such maintenance
                           agreement, warranty or guaranty. The aforesaid
                           assignment shall not in any way be deemed to limit,

                           Telcordia shall not incur any duties arising out of
                           any manufacturer's, supplier's or publisher's
                           warranties or guarantees, except as otherwise
                           expressly set forth herein. Further, Telcordia shall
                           not incur any liability whatsoever arising out of any
                           claims by NAPA or breach of any manufacturer's,
                           supplier's or publisher's warranties or guarantees
                           applicable to the Software.

                  o        DELIVERY AND INSPECTION. NAPA will accept the
                           Software provided by Telcordia upon its delivery to
                           the Permanent NAP.

                  o        LOSS OR DAMAGE. Except for the negligence or willful
                           misconduct of Telcordia related to the Services
                           provided by Telcordia, NAPA shall bear the entire
                           risk of loss, theft, destruction, or damage of the
                           Software provided by Telcordia or any portion thereof
                           from any cause whatsoever. The total or partial
                           destruction of any such Software, or total or partial
                           loss of use or possession thereof by NAPA, shall not
                           release or relieve NAPA from the duty to pay the fees
                           herein provided. Telcordia shall not be obligated to
                           undertake, by litigation or otherwise, the collection
                           of any claim against any person for loss or damage of
                           such Software.

                  o        ULTIMATE TAX AND LIEN RESPONSIBILITY. Telcordia's
                           good faith acceptance of a tax exemption certificate
                           does not represent an assurance that the State will
                           also accept the certificate as valid at the time of

                           audit adjustment and the aggregate of tax, interest,
                           and penalty, if a certificate is subsequently denied.

                  o        INDEMNITY. Except for the negligence or willful
                           misconduct of Telcordia related to the Services
                           provided in this section and/or any other related

                           Telcordia harmless from and against any and all
                           claims, costs, expenses, damages, and liabilities
                           arising from or pertaining to the use, possession, or

                            SCOPE CHANGE CONTROL FORM

This Scope Change No. 1NAP10-3 ("Scope Change") amends the Work Statement,
Contract No. 1NAP10, ("Work Statement") between NAP of the Americas, Inc.
("NAPA"), a wholly owned subsidiary of Terremark Worldwide, Inc. ("Terremark"),
and Telcordia Technologies, Inc. ("Telcordia"), and is effective as of this 17
day of April, 2001 ("Scope Change"). This Scope Change incorporates all the
terms and conditions of the Work Statement and Agreement except as may be
otherwise modified herein for the limited purpose set forth herein.

         1.       Title of Scope Change: Resale of Hardware for Permanent NAP in
                  Miami.

         2.       Date of Scope Change: April 17, 2001

         3.       Originator of Scope Change: Max Figueroa

         4.       Reason for the Scope Change: NAPA has requested that Telcordia
                  purchase hardware in support of the development of a Network
                  Operations Center (NOC) at the Permanent NAP facility in
                  Miami.

         5.       Details of the Scope Change (including any specifications):
                  Telcordia shall perform the following services:

                  o  Upon NAPA's written approval of the quote for hardware, and
                     associated support contracts, contained in Attachment A
                     (Hardware), NAPA will issue a Purchase Order to Telcordia
                     for the full amount of the hardware. Telcordia shall then
                     order and take delivery of such Hardware.

                  o  Upon completion of the development of the solution using
                     the Hardware as described in Work Statement 1NAP10,
                     Telcordia shall ship, at NAPA's expense including insurance
                     coverage, the Hardware to a secure location designated by
                     NAPA in Miami. All equipment will be considered accepted by
                     NAPA upon delivery to its designated destination.

                  o  In no event shall Telcordia have any liability in
                     connection with shipment, nor shall the carrier be deemed
                     to be an agent of Telcordia. Telcordia shall not be liable
                     for damage or penalty for delay in delivery or for failure
                     to give notice of any delay.

           TELCORDIA TECHNOLOGIES, INC. AND NAP OF THE AMERICAS, INC.
                        CONFIDENTIAL - RESTRICTED ACCESS
This document and the confidential information it contains shall be distributed,
   routed or made available solely to authorized persons having a need to know
    within Telcordia and NAPA, except with written permission of Telcordia.

                        CONFIDENTIAL - RESTRICTED ACCESS

         6.       Implementation timetable of the Scope Change: Telcordia shall
                  place orders for Hardware by April 20, 2001.

         7.       Additional fees or refund, if any, of the Scope Change: NAPA
                  shall pay Telcordia for the Hardware on the basis of a fixed
                  price. Telcordia shall invoice NAPA for the entire amount due
                  upon signature of this change order by both parties. Telcordia
                  understands that NAPA is pursuing financing for the Hardware
                  but that such financing will not be completed before Telcordia
                  issues the purchase order. As a result, NAPA agrees to pay
                  Telcordia the full amount of $275,520.53 ("Advance Payment")
                  via bank wire transfer in advance of Telcordia's issuance of a
                  purchase order for the Hardware.

                  If NAPA is successful in closing financing with a leasing
                  company ("Leasing Company") for the Hardware within thirty
                  (30) days of the signature of this Change Order, and Telcordia
                  receives written evidence from such Leasing Company that
                  payment has been made to each of the vendors listed in
                  Attachment A ("Vendor Payment") for the equipment within the
                  same thirty (30) day period, Telcordia will return to NAPA the
                  Vendor Payment either as a cash payment or as a credit to the
                  oldest outstanding Telcordia invoice generated for NAPA. The
                  form of return payment will be either a check or a credit to
                  NAPA, at NAPA's option, subject to the following: (1) If NAPA
                  has an outstanding debit balance with Telcordia, the credit
                  and/or check shall be reduced by the amount of the debit
                  balance and the debit balance will be satisfied first; and (2)
                  Telcordia shall retain the difference between the Advance
                  Payment and Vendor Payment in consideration for Telcordia
                  purchasing Hardware for resale to NAPA. Telcordia shall also
                  provide the Leasing Company with an assignment letter
                  assigning full right and title to the Hardware purchased in
                  satisfaction of all Telcordia obligations under this
                  agreement.

         8.       Impact of the Scope Change on other aspects of the Schedule,
                  including but not limited to, the overall payment schedule,
                  contractual provisions, and Deliverable schedules:

The following additional terms apply to the resale of hardware as described in
this change order.

                  o  TRANSFER OF TITLE: After payment in full is received by
                     Telcordia for the Hardware, Telcordia will ship such items,
                     at NAPA' s expense including insurance coverage, to a
                     location designated by NAPA, in accordance with the
                     schedule in Contract No. 1NAP10. Title to such Hardware
                     obtained by Telcordia for resale to NAPA shall pass to NAPA
                     upon receipt of the items so purchased.

                  o  HARDWARE AND SOFTWARE: NAPA further acknowledges that
                     Telcordia HAS NOT MADE, AND DOES NOT MAKE, ANY WARRANTY OR
                     REPRESENTATION, EITHER EXPRESSED OR IMPLIED, OR ANY KIND
                     WHATSOEVER WITH RESPECT TO THE HARDWARE ACQUIRED BY NAPA

                     AS TO THE FITNESS. DESIGN, OR CONDITION OF THE HARDWARE;
                     (2) AS TO THE MERCHANTABILITY OF THE HARDWARE OR ITS
                     Fitness FOR ANY PARTICULAR PURPOSE; (3) as to the quality
                     or capacity of the Hardware , the materials in the
                     Hardware, or workmanship in the Hardware; (4) as to any
                     latent defects in the Hardware; (5) as to any patent
                     infringement; and (6) as to the compliance of the Hardware
                     with any requirements of any law, rule, specification, or
                     contract pertaining thereto.

                  o  PROBLEMS WITH HARDWARE. If the Hardware is not properly
                     installed, does not operate as represented or warranted by
                     the manufacturer, publisher or the supplier, NAPA shall
                     make a claim on account thereof solely against the
                     supplier, publisher or manufacturer and shall,
                     nevertheless, pay Telcordia all fees payable hereunder. As
                     between NAPA and Telcordia, and only in those instances
                     where the manufacturer, publisher or supplier has provided
                     any maintenance agreement, warranty or guaranty of any
                     nature whatsoever applicable to the Hardware, Telcordia
                     hereby assigns to NAPA whatever assignable interest
                     Telcordia may have in such maintenance agreement, warranty
                     or guaranty. The aforesaid assignment shall not in any way
                     be deemed to limit, negate, or otherwise affect the
                     disclaimer of warranties contained in the preceding
                     paragraphs. Telcordia shall not incur any duties arising
                     out of any manufacturer's, supplier's or publisher's
                     warranties or guarantees, except as otherwise expressly set
                     forth herein. Further, Telcordia shall not incur any
                     liability whatsoever arising out of any claims by NAPA or
                     breach of any manufacturer's, supplier's or publisher's
                     warranties or guarantees applicable to the Hardware.

                  o  DELIVERY AND INSPECTION. NAPA will accept the Hardware
                     provided by Telcordia upon its delivery to the Permanent
                     NAP.

                  o  LOSS OR DAMAGE. Except for the negligence or willful
                     misconduct of Telcordia related to the Services provided by
                     Telcordia, NAPA shall bear the entire risk of loss, theft,
                     destruction, or damage of the Hardware provided by
                     Telcordia or any portion thereof from any cause whatsoever.
                     The total or partial destruction of any such Hardware, or
                     total or partial loss of use or possession thereof by NAPA,
                     shall not release or relieve NAPA from the duty to pay the
                     fees herein provided. Telcordia shall not be obligated to
                     undertake, by litigation or otherwise, the collection of
                     any claim against any person for loss or damage of such
                     Hardware.

                  o  ULTIMATE TAX AND LIEN RESPONSIBILITY. Telcordia's good
                     faith acceptance of a tax exemption certificate does not
                     represent an assurance that the State will also accept the
                     certificate as valid at the time of audit review. NAPA is
                     responsible for any future audit adjustment if the
                     certificate is not accepted. NAPA agrees to reimburse
                     Telcordia for the amount of audit adjustment and the
                     aggregate of tax, interest, and penalty, if a certificate
                     is subsequently denied.

                     of Telcordia related to the Services provided in this
                     section and/or any other related Work Statement, (i) NAPA
                     assumes the risk of liability arising from or pertaining to

                     NAPA hereby agrees to defend, indemnify and hold Telcordia
                     harmless from and against any and all claims, costs,
                     expenses, damages, and liabilities arising from or
                     pertaining to the use, possession, or operation of such

                            SCOPE CHANGE CONTROL FORM

This Scope Change No. 1NAPIO-4 ("Scope Change") amends the Work Statement,
Contract No. 1NAPIO, ("Work Statement") between NAP of the Americas, Inc.
("NAPA"), a wholly owned subsidiary of Terremark Worldwide, Inc. ("Terremark"),
and Telcordia Technologies, Inc. ("Telcordia"), and is effective as of this 13
day of APRIL, 2001 ("Scope Change"). This Scope Change incorporates all the
terms and conditions of the Work Statement and Agreement except as may be
otherwise modified herein for the limited purpose set forth herein.

         1.       Title of Scope Change: Resale of Software for Permanent NAP in
                  Miami.

         2.       Date of Scope Change:  April 13, 2001

         3.       Originator of Scope Change:  Max Figueroa

         4.       Reason for the Scope Change: NAPA has requested that Telcordia
                  purchase software ("Software") and the associated professional
                  services provided by the designated software vendors outlined
                  in Attachment A, in support of the development of a Network
                  Operations Center (NOC) at the Permanent NAP facility in
                  Miami.

         5.       Details of the Scope Change (including any specifications):
                  Telcordia shall perform the following services:

                  o        Upon NAPA's approval of the quote for Software, and
                           associated support contracts, contained in Attachment
                           A , NAPA will issue a Purchase Order to Telcordia for
                           the full amount of the Software. Telcordia shall then
                           order and take delivery of such Software.

                  o        Upon completion of the development of the solution
                           using the Software as described in Work Statement
                           1NAP1O, Telcordia shall ship, at NAPA's expense
                           including insurance coverage, the Software to a
                           secure location designated by NAPA in Miami. All
                           equipment and integrated Software will be considered
                           accepted by NAPA upon delivery to its designated
                           destination.

                  o        In no event shall Telcordia have any liability in
                           connection with shipment, nor shall the carrier be
                           deemed to be an agent of Telcordia. Telcordia shall
                           not be liable for damage or penalty for delay in
                           delivery or for failure to give notice of any delay.

         6.       Implementation timetable of the Scope Change: Telcordia shall
                  place orders for the Software by April 25, 2001.

 Telcordia Technologies, Inc. and NAP of the Americas, Inc. - Restricted Access
       This document and the confidential information it contains shall be
   distributed, routed or made available solely to authorized persons having
             a need to know within Telcordia and NAPA, except with
                        written permission of Telcordia.

                        Confidential - Restricted Access

         7.       Additional fees or refund, if any, of the Scope Change: NAPA
                  shall pay Telcordia for the Software on the basis of a fixed
                  price. Telcordia shall invoice NAPA for the entire amount due
                  upon signature of this change order by both parties. Telcordia
                  understands that NAPA is pursuing financing for the Software,
                  but that such financing will not be completed before Telcordia
                  issues the purchase order. As a result, NAPA agrees to pay
                  Telcordia the full amount of $277,352.14 ("Advance Payment")
                  in advance of Telcordia's issuance of a purchase order for the
                  Software.

                  If NAPA is successful in closing financing with a leasing
                  company ("Leasing Company") for the Software within thirty
                  (30) days of the signature of this Change Order, and Telcordia
                  receives written evidence from such Leasing Company that
                  payment has been made to each of the vendors, as listed in
                  Attachment A ("Vendor Payment") for the Software within the
                  same thirty (30) day period, Telcordia will return to NAPA the
                  Vendor Payment either as a cash payment or as a credit to the
                  oldest outstanding Telcordia invoice generated for NAPA. The
                  form of return payment will be either a check or a credit to
                  NAPA, at NAPA's option, subject to the following: (1) If NAPA
                  has an outstanding debit balance with Telcordia, the credit
                  and/or check shall be reduced by the amount of the debit
                  balance and the debit balance will be satisfied first; and (2)
                  Telcordia shall retain the difference between the Advance
                  Payment and Vendor Payment in consideration for Telcordia
                  purchasing Software for resale to NAPA. Telcordia shall also
                  provide the Leasing Company with an assignment letter
                  assigning full right and title to the Software purchased in
                  satisfaction of all Telcordia obligations under this
                  agreement.

         8.       Impact of the Scope Change on other aspects of the Schedule,
                  including but not limited to, the overall payment schedule,
                  contractual provisions, and Deliverable schedules:

The following additional terms apply to the resale of Software as described in
this change order.

         o        SOFTWARE LICENSES: After payment in full is received by
                  Telcordia for the Software, Telcordia will accept delivery and
                  install the Software. Telcordia will ship such Software, at
                  NAPA's expense including insurance coverage, to a location
                  designated by NAPA, in accordance with the schedule in
                  Contract No. 1NAP10. NAPA agrees to pay Telcordia the
                  licensing fees for the Third Party Software in accordance with
                  Section 7 above. In addition, NAPA agrees to be bound by the
                  licensing terms and conditions accompanying the Third Party
                  Software, whether in the form of "shrink wrap licenses" as
                  part of the documentation or "click accept" licenses
                  incorporated as part of the Third Party Software. Ownership of
                  the Software shall remain at all times with the publisher of
                  such Software.

         o        SOFTWARE: NAPA FURTHER ACKNOWLEDGES THAT TELCORDIA HAS NOT
                  MADE, AND DOES NOT MAKE, ANY WARRANTY OR REPRESENTATION,
                  EITHER EXPRESSED OR IMPLIED, OR ANY KIND WHATSOEVER WITH
                  RESPECT TO THE SOFTWARE ACQUIRED BY NAPA UNDER THIS CHANGE
                  ORDER, INCLUDING BUT NOT LIMITED TO: (1) AS TO THE FITNESS,
                  DESIGN, OR CONDITION OF THE SOFTWARE; (2) AS TO THE
                  MERCHANTABILITY OF THE SOFTWARE OR ITS FITNESS FOR ANY
                  PARTICULAR PURPOSE; (3) as to the quality or capacity of the
                  Software; (4) as to any latent defects in the Software; (5) as
                  to any patent infringement; and (6) as to the compliance of
                  the Software with any requirements of any law, rule,
                  specification, or contract pertaining thereto.

         o        PROBLEMS WITH SOFTWARE. If the Software is not properly
                  installed, does not operate as represented or warranted by the
                  manufacturer, publisher or the supplier, NAPA shall make a
                  claim on account thereof solely against the supplier,
                  publisher or manufacturer and shall, nevertheless, pay
                  Telcordia all fees payable hereunder. As between NAPA and
                  Telcordia, and only in those instances where the manufacturer,
                  publisher or supplier has provided any maintenance agreement,
                  warranty or guaranty of any nature whatsoever applicable to
                  the Software, Telcordia hereby assigns to NAPA whatever
                  assignable interest Telcordia may have in such maintenance
                  agreement, warranty or guaranty. The aforesaid assignment
                  shall not in any way be deemed to limit, negate, or otherwise
                  affect the disclaimer of warranties contained in the preceding
                  paragraphs. Telcordia shall not incur any duties arising out
                  of any manufacturer's, supplier's or publisher's warranties or
                  guarantees, except as otherwise expressly set forth herein.
                  Further, Telcordia shall not incur any liability whatsoever
                  arising out of any claims by NAPA or breach of any
                  manufacturer's, supplier's or publisher's warranties or
                  guarantees applicable to the Software.

         o        DELIVERY AND INSPECTION. NAPA will accept the Software
                  provided by Telcordia upon its delivery to the Permanent NAP.

         o        LOSS OR DAMAGE. Except for the negligence or willful
                  misconduct of Telcordia related to the Services provided by
                  Telcordia, NAPA shall bear the entire risk of loss, theft,
                  destruction, or damage of the Software provided by Telcordia
                  or any portion thereof from any cause whatsoever. The total or
                  partial destruction of any such Software, or total or partial
                  loss of use or possession thereof by NAPA, shall not release

         o        ULTIMATE TAX AND LIEN RESPONSIBILITY. Telcordia's good faith
                  acceptance of a tax exemption certificate does not represent
                  an assurance that the State will also accept the certificate
                  as valid at the time of audit review. NAPA is responsible for
                  any future audit adjustment if the certificate is not
                  accepted. NAPA agrees to reimburse Telcordia for the amount of
                  audit adjustment and the aggregate of tax, interest, and
                  penalty, if a certificate is subsequently denied.

         o        INDEMNITY. Except for the negligence or willful misconduct of
                  Telcordia related to the Services provided in this section
                  and/or any other related Work Statement, (i) NAPA assumes the
                  risk of liability arising from or pertaining to the
                  possession, operation, or use of the Software; and (ii) NAPA
                  hereby agrees to defend, indemnify and hold Telcordia harmless
                  from and against any and all claims, costs, expenses, damages,
