     individual Colocation Schedule or on the date Focal completes the build-out
     of the rack location, whichever is later. The minimum term of the
     Customer's license to occupy the equipment rack(s) shall be the period set
     forth in the Colocation Schedule (the "Minimum Term").

B.   If Focal fails for any reason to tender possession of the rack location to
     Customer on or before the Requested Service Date (specified in the Colocate
     Schedule relevant thereto) this Agreement shall not be void or violable.
     Notwithstanding the foregoing, if Focal fails to tender possession of the
     equipment rack(s) to Customer within a sixty (60) day period after such
     Requested Service Date (due to any reason other than the acts or omissions
     of Customer), Customer may, upon written notice to Focal, declare relevant
     Colocate Schedule null and void with no further obligation by Customer
     under the relevant Colocate Schedule, and Focal shall refund all fees and
     charges paid in advance by Customer. In the Event that Focal is delayed in
     tendering possession of the equipment rack(s) to Customer for any reason
     other than the acts or omissions of Customer, Customer shall not be
     obligated to pay the Occupancy Fee or Service Fee (as hereinafter defined)
     hereunder until such time as Focal tenders possession of the equipment rack
     location to the Customer. Except as provided herein, Focal shall not be
     liable to Customer in any way as a result of such delay or failure to
     tender possession.

C.   Subject to the conditions specified in this Section II, and provided

     duration of the Renewal Periods), such election to be exercised at the sole
     discretion of Focal.

E.   Following the expiration of the Term for each equipment rack or failure of
     the Parties to enter into any Renewal Periods, Customer's license shall

     Customer agrees to remove the Equipment and other property that has been
     installed by Customer or Customer's agents. In the event such equipment or

     eminent domain by any authority having such power, Focal shall have the
     right to terminate this Agreement. Focal shall attempt to give Customer
     reasonable advance notice of the removal schedule. Customer shall have no
     claim against Focal for any relocation expenses, any part of any award that
     may be made for such taking or the value of any unexpired term or renewed
     periods that result from a termination by Focal under this provision, or
     any loss of business from full or partial interruption of interference due
     to any termination. However, nothing contained in this Agreement shall
     prohibit Customer from seeking any relief or remedy against the condemning
     authority in the event of an eminent domain proceeding or condemnation that
     affects the equipment rack location.

     contractor, and Customer will remain solely responsible for the selection
     of the supplier or contractor and all payments for construction work.

     the interior or exterior portions of the equipment rack location, including
     any cabling or power supplies for the Equipment, without obtaining Focal's
     written approval for Customer to have the work performed or have Focal

to a site which shall afford comparable environmental conditions for the
Equipment and comparable accessibility to the Equipment. Focal and Customer will
work together in good faith to minimize any disruption of Customer's service as
a result of such relocation. Focal shall be responsible for the cost of

less than Five Hundred Thousand Dollars ($500,000.00) per occurrence, (iii)

     rendered hereunder, Focal may, at its sole option and with written notice,
     issue a default notice letter to Customer, demanding the default condition
     be cured. If the default condition is not remedied within the time period
     specified in the notice letter, which shall not be less than fourteen (14)
     calendar days, Focal may then, without the necessity of any further notice,
     discontinue performance and terminate this Agreement, for default, and
     pursue any other remedies available at law or in equity. Focal's failure to
     exercise any of its rights hereunder shall not constitute or be construed
     by Customer as being a waiver of any past, present, or future right or
     remedy.

B.   At any time during the term of this Agreement, Focal may, at Focal's sole
     option, immediately terminate this Agreement if Customer is not then
     maintaining the Equipment solely for the purpose of originating and/or
     terminating telecommunications transmissions carried over the Focal Network
     or as otherwise set forth in Paragraph 1 of this Agreement, or

<PAGE>

     pursuant to the terms and conditions, if any, contained in any Colocation
     Schedule identified herein.

C.   If Customer commits an act of default with respect to the purchase of
     telecommunications service from Focal, which would entitle Focal under its

obligations of the parties shall commence on the Acceptance Date (hereinafter
defined) and continue from the Commencement Date (hereinafter defined) for the
number of months set forth in the LEASE. The Acceptance Date with respect to
each item of EQUIPMENT shall be the sixteenth (16th) day after the date of
shipment to LESSEE. The Commencement Date shall be the first day of the month
following the Acceptance Date. THIS LEASE IS NON-CANCELABLE FOR THE FULL TERM

by LESSOR in writing by certified mail, return receipt. Ninety (90) days prior
to the expiration date of the initial term or any of the non-cancelable
increments of the LEASE.

3.       PAYMENT. LESSEE agrees to pay to LESSOR monthly LEASE payments as
stated herein in advance on the Commencement Date and on the first day of each
month thereafter during the LEASE term. If the Commencement Date is not the same
date as the Acceptance Date, LESSEE shall pay LESSOR interim rent on the
Acceptance Date for that period of time from the Acceptance Date up to, but not
including the Commencement Date in an amount equal to 1/30th of the monthly
LEASE payment multiplied by the number of days from (and including) the

WARRANTY, PROMISE, OR COVENANT, EXPRESS OR IMPLIEDM AS TO THE CONDITION,
QUALITY, DURABILITY, CAPABILITY, FUNCTION, PERFORMANCE, OR SUITABILITY OF THE

condition, or promise under this LEASE. (C) All terms and conditions hereof
shall be binding upon all successors and assigns of the parties hereto but only
to the extent such successors and assigns are permitted hereunder.

6.       UCC FILINGS. LESSEE hereby agrees to execute such financing statements,
amendments thereto and other instruments as may be requested by LESSOR and
hereby constitutes and appoints LESSOR its true and lawful attorney-in-fact to

quiet and peaceful use of the EQUIPMENT. LESSOR shall be permitted to inspect
the EQUIPMENT during LESSEE'S regular working hours.

9.       REPAIRS. LESSEE, at its own expense, shall keep the EQUIPMENT in good
repair, and maintain a service agreement in full force throughout the term of
the LEASE which fulfills all of the manufacturer's or vendor's maintenance
requirements as set forth in its full service maintenance contract.
Notwithstanding, LESSEE agrees to pay LESSOR for any expense incurred to cause
the EQUIPMENT to meet vendor's specifications. LESSEE shall pay such charges
immediately upon request.

10.      INSURANCE. LESSEE shall provide, and pay for (a) insurance against the
loss or theft of or damage to the EQUIPMENT for the full replacement and (b)
public liability and property damage insurance naming LESSOR as Loss Payee or
Additional Insured. Upon request from LESSOR, LESSEE shall provide with a
Certificate of Insurance.

assessments, charges and taxes (municipal, state and federal) which are imposed
upon this LEASE or the EQUIPMENT or its ownership, leasing, renting, possession
or use while it is subject to this LEASE, excluding, however, taxes based on

between the parties.

16.      REMEDIES. Unless LESSSSEE cures an event of default within 10 business

that upon the occurrence of an Event of Default, LESSOR may take one or more of
the following actions: (i) declare the entire amount of the remaining LEASE
payments, including arrearages, due and immediately payable, (ii) take peaceful

may otherwise limit or modify any of LESSOR'S rights or remedies under this
paragraph.

17.      LESSOR'S EXPENSES: LESSEE shall pay LESSOR all costs and expenses,
including reasonable attorney's fees, incurred by LESSOR in exercising any of
its rights or remedies hereunder. To the extent allowed by law, LESSEE shall be

each month the payment is delinquent, or the maximum rate permitted by law.

18.      INDEMNITY: LESSEE shall indemnify LESSOR against, and hold LESSOR
harmless from, any and all claims, actions, suits, proceedings, costs, expenses,
damages and liabilities, including reasonable attorney's fees, arising out of,
connected with, or resulting from this LEASE or the EQUIPMENT without
limitation. The indemnities contained herein shall survive termination of this
LEASE.

19.      NON-WAIVER. Lessor's failure to require strict performance by LESSEE of
any of the provisions of this LEASE shall not be a waiver thereof.

20.      SEVERABILITY. If any of provision of this LEASE be declared invalid,
such provision shall be inapplicable and deemed omitted, but the remaining
provisions, including the default and remedy provisions, shall remain in full
