                         SECTION 2. DELIVERY OF SERVICE
                         ------------------------------

2.1 SUBMISSION AND ACCEPTANCE OF CUSTOMER ORDER FORMS. Customer Orders will
contain a description of the Service, the nonrecurring charges and monthly
recurring charges for Service and any applicable Service Term. Upon receipt of a
Customer Order signed by Customer for Services governed by this Agreement, if
Level 3 determines (in its sole discretion) to accept the Customer Order, Level
3 will deliver a Customer Welcome Letter for the requested Service (or some
portion of the Services). Level 3 will endeavor to determine whether to accept a
Customer Order and (if so) deliver a Customer Welcome Letter within one week of
receiving the Customer Order from Customer, which such Costumer Welcome Letter
will indicate if the requested Service, or any portion thereof, is not an On-Net
Service, as defined in Section 2.6. In the event that the Customer Welcome
Letter contains a Customer Commit Date that is more than twenty (20) business
days after the date of installation requested by Customer or indicates that the
Service is not an On-Net Service, then Customer may (by written notice delivered
to Level 3 no later than three (3) business days after receipt of the Customer
Welcome Letter) terminate the Customer Order without termination liability.

2.2 CREDIT APPROVALS. Customer will provide Level 3 with credit information as
requested, and delivery of Service is subject to credit approval. Level 3 may
from time to time require Customer to make a deposit as a condition to
acceptance of Customer Orders or continuation of Service (the amount of the
deposit required will be subject to the mutual agreement of the parties, but in
no case shall equal more than two (2) months of the MRC for all Services ordered
hereunder), provided, however, that as long as Customer makes its payments in a
timely fashion in accordance with this Agreement, Level 3 may not request such a
deposit. When Service to Customer is terminated, the amount of the deposit will
be credited to amounts owed by Customer and any remaining credit balance will be
refunded.

2.3 CUSTOMER PREMISES. Customer will allow access to the Customer Premises to
the extent reasonably necessary for Level 3 to install and maintain Facilities.
All such access will be subject to Customer's security procedures. Customer will
be responsible for providing and maintaining, at its own expense, the level of
power, heating and air conditioning necessary to maintain the proper environment
for Facilities on the Customer Premises, and shall reimburse Level 3 for the
reasonable cost of repairing or replacing any Facilities damaged or destroyed as
a direct result of Customer's failure to do so.

2.4 FACILITIES. Except as otherwise agreed, title to all Facilities shall remain
with Level 3. Except in cases of emergency, Customer shall not, and shall not
permit others to, rearrange, disconnect, remove, repair, or otherwise tamper
with any Facilities, without the prior written consent of Level 3. Customer
agrees to allow Level 3 to remove the Facilities from the Customer Premises:
(A) after termination, expiration or cancellation of the Service Term in
connection with which the Facilities were used; or
(B) for repair, replacement or similar correction, subject to the Service Levels
set forth in Exhibit D hereto.

2.5 INITIAL CUSTOMER ORDER AND ACCEPTANCE. Customer hereby submits, and Level 3
hereby accepts, a Customer Order for the Services set forth in Exhibit A
attached hereto and incorporated herein by this reference. The Service Term for
all of the Services listed in Exhibit A shall be three (3) years from the
Service Commencement Date. The Customer Commit Date and pricing for such
Services is set forth in Exhibit A. The monthly recurring charges for the
initially ordered Services shall be as stated in Exhibit A for the first year of
the Term, and shall thereafter be subject to adjustment as stated in Section 3.7
hereof. Customer shall be entitled to postpone (without penalty) the Service
Commencement Date with respect to the Services listed in Exhibit A by no more
than thirty (30) days for each circuit listed.

2.6 ON-NET SERVICES. "On-Net Services" shall mean Services delivered entirely
within and over Level 3's owned network, including without limitation, all
Services set forth in the Initial Service Order attached as Exhibit A hereto and
(3)Center Colocation, as described in Exhibit B attached hereto. With respect to
any subsequent Customer Orders during the Term of this Agreement, Level 3 will
provide such additional Services as On-Net Services if and to the extent that
Level 3 has existing facilities which would allow it to do so.


                                       2
<PAGE>


2.7 TECHNOLOGY UPGRADE AND SERVICE PORTABILITY. Customer shall have the right to
change intercity Services that are delivered entirely on Level 3's owned network
("Long Haul On-Net Services") purchased under this Agreement to alternative Long
Haul On-Net Services from Level 3, provided, however, that the total monthly
recurring charges (as set forth herein or as otherwise agreed by the parties) of
all such alternative Long Haul On-Net Services is at least equal to the monthly
recurring charges of the original Long Haul On-Net Services which they replace.
Pursuant to this Section, Customer may replace existing Long Haul On-Net
Services with alternate Long Haul On-Net Services (including converting (3)Link
Private Line Services to wavelength services) or may substitute one circuit of
Long Haul On-Net Service for another circuit or circuits of Long Haul On-Net
Services.

                         SECTION 3. BILLING AND PAYMENT
                         ------------------------------

3.1 COMMENCEMENT OF BILLING. Upon installation and testing of the Service
ordered in any Customer Order, Level 3 will deliver a Connection Notice to
Customer. Upon receipt of the Connection Notice, Customer shall have a period of
seventy two (72) hours to confirm that the Service has been installed and is
properly functioning. If Customer discovers defects in the Service, Customer may
reject the Connection Notice by written notice to Level 3 (which notice may be
in the form of an electronic mail delivered to Level 3's designated address). If
Customer has not delivered written notice rejecting the Connection Notice within
such 72-hour period, billing shall commence on the Service Commencement Date,
regardless of whether Customer has procured services from other carriers needed
to operate the Service.

3.2 PAYMENT OF INVOICES.
(A) Invoices are delivered monthly. Level 3 bills in advance for Service to be
provided during the upcoming month, except for charges which are dependent upon
usage of Service, which are billed in arrears. Billing for partial months is
prorated based on a calendar month. All invoices are due thirty (30) days after
the receipt of invoice. Past due amounts, other than amounts subject to a
reasonable dispute, bear interest at a rate of 1.5% per month (or the highest
rate allowed by law, whichever is less) beginning from the date due until paid
in full. The applicable Level 3 circuit ID must be referenced on all invoices in
order for the document to be processed for payment.
(B) Customer shall have the right to reasonably dispute any charges included on
Level 3 invoices. In the event of any such dispute, the portion of the invoice
which is undisputed shall be paid as provided above. Customer shall have the
right to withhold payment of any reasonably disputed amount, provided that
Customer gives Level 3 written notice of the amount and reason for the dispute
within sixty (60) days after receipt of the invoice on which the disputed
charges first appeared. In the event that the disputed item is resolved in favor
of Level 3, then interest on the unpaid disputed amount shall be due and owing
from the date upon which such payment was originally due.

3.3 TAXES AND FEES. Level 3's quoted rates do not include taxes. Customer shall
be responsible for and shall pay all taxes, including sales, use, excise, gross
receipts, value added, access, bypass, franchise, telecommunications,
consumption, specifically imposed on or based on the provision, sale or use of
the Service, including taxes imposed directly on Level 3. Customer shall not be
responsible for payment of taxes which are based on Level 3's net income. In the
event that Customer believes that, with respect to the Service provided
hereunder, Customer is tax exempt, Customer shall submit to Level 3 a properly
executed exemption certificate or other document legally sufficient to prove
exemption from taxes under applicable law. If Level 3 believes that, with
respect to the Service provided hereunder, Customer's exemption certifications
are not applicable, Level 3 shall provide written notification of the denial
along with the identification of the relevant jurisdiction imposing the taxes.
Customer shall be responsible for maintaining its tax exempt status and if such
status should change during the term of this Agreement, Customer shall be
responsible for providing Level 3 with written notice of such change in
Customer's taxable status.

3.4 REGULATORY AND LEGAL CHANGES. In the event of any change in applicable law,
regulation, decision, rule or order that materially increases the costs or other
terms of delivery of Service, Level 3 and Customer will negotiate regarding the
rates to be charged to Customer to reflect such increase in cost and, in the
event that the parties are unable to reach agreement within sixty (60) days
after Level 3's delivery of written notice requesting renegotiation, then (a)
Level 3 may pass such increased costs through to Customer, and (b) if Level 3
passes on such increased costs, Customer may thereafter terminate the affected
Customer Order without termination liability by delivering written notice of
termination no later than sixty (60) days after the effective date of the rate
increase (which written notice shall specify a future date selected by Customer
for termination of the affected Service), and the Revenue Commitment shall be
reduced by the price for such Customer Order.

3.5 TERMINATION CHARGES. Unless otherwise provided herein, in the event that
Customer cancels a Customer Order, in whole or in part, or all or part of a
Customer Order is cancelled by Level 3 due to a failure of Customer to comply
with this Agreement, Customer shall be responsible for the payment of
termination charges. The termination


                                       3
<PAGE>


charge shall be the sum of the amount set forth in paragraph (A) or (B) below,
as applicable:

(A) For Terminations Prior to the Receipt of a Connection Notice: The amount
which is the greater of:

                  1. any actual third party cancellation/termination charges and
         other reasonable and actual Level 3 out of pocket expenses directly
         related to the installation and/or cancellation of Service, or

                  2. as the case may be:

                           (i) [**] monthly recurring charges for the
                  cancelled Service if written notice of cancellation is
                  received by Level 3 more than five (5) business days prior to
                  the Customer Commit Date; or

                           (ii) [**] monthly recurring charges for the
                  cancelled Service if written notice of cancellation is
                  received by Level 3 five (5) business days or less prior to
                  the Customer Commit Date.

(B) For Terminations After Receipt of a Connection Notice: The amount which is
the greater of:
                  1. any actual third party cancellation/termination charges and
         other reasonable and actual Level 3 out of pocket expenses directly
         related to the installation and/or termination of Service; or

                  2. [**] of the unpaid monthly recurring charges that would
         have been incurred for the Service for months 1-12 of the Service Term,
         plus [**] of the unpaid monthly recurring charges that would have been
         incurred for the Service for months 13 through the end of the Service
         Term.

Notwithstanding the foregoing, no termination charge shall be assessed in the
event that Customer cancels Service under Section 4.3 hereof, or in the event
that Customer terminates this Agreement as a result of a material, uncured
default by Level 3. In the event that Customer terminates all or part of a
Service Order after delivery of a Connection Notice, Customer shall specify the
date upon which Services will be terminated (which shall in no event be sooner
than thirty (30) days following delivery of written notice of termination of
Service). Customer shall be responsible for the payment of all charges for the
Service through the effective date of termination of Service.

3.6 REVENUE COMMITMENT. During the Term, following a ramp period during which
the initially ordered Services listed in Exhibit A shall be installed (the "Ramp
Period"), Customer agrees that the monthly recurring charges for On-Net Services
delivered hereunder will equal or exceed the following amounts (each a "Revenue
Commitment"):

                  "Contract Year"                   Revenue Commitment
                  -------------------------------------------------------
                  1-2                               [**] per month
                   3                                [**] every six months

                  In addition, Customer agrees to an additional Revenue
                  Commitment of [**], which may be satisfied through the
                  purchase of On-Net Services during the Term of the Agreement;
                  provided, however, that any shortfall (as described in
                  paragraph (B) below) for failure to meet such additional
                  Revenue Commitment shall be invoiced only at the end of
                  Contract Year 3.

(A) A Contract Year is measured from and after the end of the Ramp Period; thus,
Contract Year 1 begins on the date the Ramp Period ends and ends one year
thereafter.

(B) The Revenue Commitment is a "take-or-pay" commitment; at the end of the
applicable period (monthly during the first two Contract Years, and every six
months during the last Contract Year), Level 3 will invoice Customer and
Customer agrees to pay Level 3, in addition to all invoiced charges for the
Service then due and owing, for the deficiency (if any) between the charges due
for Customer's actual usage of On-Net Services for the particular period and the
Revenue Commitment. The Revenue Commitment shall be satisfied once Customer's
total payments for On-Net Services reaches [**], and upon Customer having made
such total payments, the Revenue Commitment will terminate, even if a Contract
Year has not ended.

(C) In determining whether the Revenue Commitment has been satisfied, Customer's
monthly payments for a certain STM-1 of Transoceanic Private Line services
provided pursuant to a separate agreement shall be included.

                  SECTION 4. DISCONTINUANCE OF CUSTOMER ORDERS
                  --------------------------------------------

4.1 DISCONTINUANCE OF CUSTOMER ORDER BY LEVEL 3. Level 3 may discontinue Service
without liability if Level 3 is prevented by applicable law from continuing
delivery of Service. Such termination or discontinuation will relieve Customer
of all payment obligations to Level 3 for Services not received. In such event,
Level 3 will use its best efforts to provide as much notice as possible prior to
any such termination or discontinuation. In addition, Level 3 may terminate
delivery of Service without liability if Customer:

(A) fails to pay or reasonably dispute pursuant to the provisions of Section 3.2
any past due balance for Service within ten (10) days after receipt of written
notice from Level 3;

(B) violates any applicable law, rule, regulation or policy of any government
authority related to Service, or makes a material misrepresentation to Level 3
in connection with the ordering or delivery of Service; or

(C) fails to cure its breach (other than a payment breach, which is addressed in
(A) above) of this Agreement or any Customer Order within thirty (30) days after
receipt of written notice thereof provided by Level 3 or (for breaches that
cannot be cured within thirty (30) days) begins to cure within thirty (30) days
and diligently pursues cure on a timely basis thereafter.

4.2 EFFECT OF DISCONTINUANCE. Upon Level 3's discontinuance of Service under
Section 4.1(A) through (D) above, Level 3 may, in addition to all other remedies
that may be available to Level 3 at law or in equity, assess and collect from
Customer any applicable termination charge calculated in accordance with Section
3.7.

4.3 DISCONTINUANCE OF CUSTOMER ORDER BY CUSTOMER.

(A) Except with respect to Services (or a portion thereof) which are local loop
services ("Off-Net Local Loop Services"), if Level 3's installation of Service
is delayed for more than twenty (20) business days beyond the Customer Commit
Date (except to the extent caused by a Force Majeure Event), Customer may (but
only prior to the delivery of the Connection Notice for such Service) terminate
and discontinue the affected Service upon written notice to Level 3 and without
payment of any termination charge and the Revenue Commitment will be reduced
accordingly.

(B) Customer may terminate and discontinue all affected Services (excluding
Unprotected Service) prior to the end of the Service Term without payment of any
applicable termination charge if: (i) such Service is Unavailable (as defined
below) on two or more separate occasions of more than eight (8) hours each in
any thirty (30) day period, and (ii) following written notice thereof from
Customer to Level 3, the same Service is Unavailable for more than twelve (12)
hours at any time within the twelve (12) month period immediately following said
notice. For purposes of the foregoing, "Unavailable" shall mean an interruption
in Service, except for any interruption which is caused by a Force Majeure Event
or which is the result of scheduled maintenance for which Customer has been
notified in advance; provided, however that Customer may terminate affected
Service without any liability if such Force Majeure Event persists for longer
than one continuous week or longer than an aggregate of twenty days over any one
year period. The duration of any interruption will commence when Customer
reports an outage to the Level 3 Customer Service and Support Organization
(1-877-4LEVEL3) and will end when the Service is operative.

(C)Customer may also terminate delivery of Service without liability if Level 3:

         (1) violates any law, rule, regulation or policy of any government
authority related to Service, or makes a material misrepresentation to Customer
in connection with the ordering or delivery of Service, which violation or
material misrepresentation (i) is not cured by Level 3 within thirty (30) days
after written notice thereof from Customer, and (ii) materially and adversely
affects the operation or Customer's use of the affected Service;

         (2) fails to cure its breach of this Agreement or any Level 3 Order
within thirty (30) days after written notice thereof provided by Customer; or

         (3) files bankruptcy, for reorganization, liquidation or insolvency, or
fails to discharge an involuntary petition therefore within sixty (60) days or
makes an assignment for the benefit of creditors.

                             SECTION 5. LIABILITIES
                             ----------------------

5.1 REMEDIES. Level 3 provides specific remedies regarding installation and
performance of Service as set forth in "Service Levels" contained in each
Customer Order. In the event of a failure to deliver Service in accordance with
the Service Levels, Customer's sole remedies are contained in (a) the Service
Levels applicable to the affected Service, or (b) Section 4.3(B).
Notwithstanding any other provision hereof, subject to Section 6.6, neither
party shall be liable for any indirect, incidental, special, consequential,
exemplary or punitive damages (including but not limited to damages for lost
profits, lost revenues or the cost of procuring replacement services) arising
out of the performance or failure to perform under any Customer Order.

5.2 DISCLAIMER OF WARRANTIES. EXCEPT AS OTHERWISE PROVIDED HEREIN, LEVEL 3 MAKES
NO WARRANTIES OR REPRESENTATIONS, EXPRESS OR IMPLIED, EITHER IN FACT OR BY
OPERATION OF LAW, STATUTORY OR OTHERWISE, INCLUDING WARRANTIES OF
MERCHANTABILITY OR FITNESS FOR A PARTICULAR USE, EXCEPT THOSE EXPRESSLY SET
FORTH IN ANY APPLICABLE SERVICE LEVELS.

or other remedy be extended, for any failure of performance or equipment due a
Force Majeure Event.

party may assign this Agreement and all Customer Orders submitted and accepted

of the assets of Customer. Customer may resell the Service to third parties,
provided that Customer agrees to indemnify, defend and hold Level 3 harmless

6.4 APPLICATION OF TARIFFS. Level 3 may elect or be required to file
tariffs with the appropriate regulatory agency respecting the delivery of
certain Service. In the event that such tariffs are filed respecting Service
ordered by Customer, then (to the extent such provisions are not inconsistent
with the terms hereof or in the Customer Order) the terms set forth in the
applicable tariff shall govern Level 3's delivery of, and Customer's consumption
or use of, such Service.

Indemnified Parties by a non-Affiliate third party and arising from or directly
related to Level 3's delivery or Customer's use of any Services, materials,
equipment, facilities or other assets provided by Level 3 under this Agreement;
except that Level 3 shall not have any indemnification obligation under this
Section to the extent such claim arises out of or is related to (i) modification
of the Services or Facilities by Customer, its employees, agents,
representatives, contractors or customers, (ii) the combination of the Services
or Facilities with Customer's services or facilities, (iii) Customer's use of

6.7 PUBLICITY AND DISCLOSURE. Neither party shall issue any publication or press
release relating to any contractual relationship between Level 3 and Customer,
except as may be required by law or agreed between the parties.

6.8 ENTIRE UNDERSTANDING. This Agreement, including any Customer Orders executed
hereunder, constitute the entire understanding of the parties related to
Service. This Agreement shall be governed and construed in accordance with the
laws of the state of Colorado.

6.9 NO WAIVER. No failure by either party to enforce any rights hereunder shall
constitute a waiver of such right(s).

6.10 ACCEPTABLE USE POLICY. Customer's use of Service shall at all times comply
with Level 3's then-current Acceptable Use Policy and Privacy Policy, as
reasonably amended by Level 3 from time to time, which are available through
Level 3's web site at www.level3.com. If any change in the Level 3 Acceptable
Use Policy materially adversely affects Customer's ability to use or resell the
Services, Customer may terminate affected Services with no termination charge or
other liability to Level 3. Level 3 will notify Customer of complaints received
by Level 3 regarding each incident of alleged violation of Level 3's Acceptable
Use Policy by Customer or third parties that have gained access to the Service
through Customer. Customer agrees that it will promptly investigate all such
complaints and take all necessary actions to remedy any actual violations of
Level 3's Acceptable Use Policy. Level 3 may identify to the complainant that
Customer, or a third party that gained access to the Service through Customer,
is investigating the complaint and may provide the complainant with the
necessary information to contact Customer directly to resolve the complaint.
Customer shall identify a representative for the purposes of receiving such
communications. Provided that such installation does not materially and
adversely affect the Service, Level 3 reserves the right to install and use, or
to have Customer install and use, any appropriate devices, at Level 3's expense,
to prevent violations of its Acceptable Use Policy, including devices designed

                            (3)CENTER(SM) COLOCATION

1. GRANT OF LICENSE. Customer is granted the right to occupy the Colocation
Space identified in a Customer Order during the Service Term, except as
otherwise provided in these Terms. Customer may submit multiple Customer Orders
requesting use of Colocation Space in multiple Level 3 facilities, each of which
shall be governed by the terms hereof. Level 3 retains the right to access any
Colocation Space for any legitimate business purpose at any time.

2. USE OF COLOCATION SPACE. Customer shall be permitted to use the Colocation
Space only for placement and maintenance of communications equipment. Customer
may access the Colocation Space (and the facility within which the Colocation
Space is located for the sole purpose of accessing the Colocation Space) twenty
four (24) hours per day, seven (7) days per week; subject to any and all rules,
regulations and access requirements imposed by Level 3 governing such access.
Customer hereby agrees, within six (6) months of the Service Commencement Date
for Colocation Space, to use the Colocation Space for placement and maintenance
of communications or Internet access equipment. Level 3 may, upon forty five
(45) days' written notice, reclaim any portion of the Colocation Space not being
used within such six (6) month period. Customer shall surrender such recaptured
Colocation Space and the monthly recurring charges shall be appropriately
reduced. No refunds shall be made to Customer regarding recaptured Colocation
Space; the Revenue Commitment, however, shall be reduced to deduct the monthly
recurring charges related to Colocation Space which is recaptured pursuant to
this provision.

3. LEVEL 3 MAINTENANCE. Level 3 shall perform janitorial services, environmental
systems maintenance, power plant maintenance and other actions as are reasonably
required to maintain the facility in which the Colocation Space is located in a
condition which is suitable for the placement of communications equipment. Level
3 shall maintain the facility in which the Colocation Space is located (but
shall not be obligated to maintain the Colocation Space itself) with a relative
humidity in the range of 47.5 to 52.5% and a maximum temperature of 78 degrees.
Customer shall maintain the Colocation Space in an orderly and safe condition,
and shall return the Colocation Space to Level 3 at the conclusion of the
Service Term set forth in the Customer Order in the same condition (reasonable
wear and tear excepted) as when such Colocation Space was delivered to Customer.
EXCEPT AS EXPRESSLY STATED HEREIN OR IN ANY CUSTOMER ORDER, THE COLOCATION SPACE
SHALL BE DELIVERED AND ACCEPTED "AS IS" BY CUSTOMER, AND NO REPRESENTATION HAS
BEEN MADE BY LEVEL 3 AS TO THE FITNESS OF THE SPACE FOR CUSTOMER'S INTENDED
PURPOSE.

4. RELEASE OF LANDLORD. If and to the extent that Level 3's underlying leases so
require (but only if they so require) Customer hereby agrees to release the
landlord (and its agents, subcontractors and employees) from all liability
relating to Customer's access to the facility and Customer's use and/or
occupancy of the Colocation Space.

5. SECURITY. Level 3 will provide and maintain in working condition card
reader(s), scanner(s) and/or other access device(s) as selected by Level 3 for
access to the colocation area of a facility. Customer shall under no
circumstances "prop open" any door to, or otherwise bypass the security measures
Level 3 has imposed for access to, the colocation area. Level 3 will provide a
locking device on Customer's Colocation Space, which Customer shall be solely
responsible for locking and/or activating such device. In the event that
unauthorized parties gain access to the facility, colocation area and/or the
Colocation Space through access cards, keys or other access devices provided to
Customer, Customer shall be responsible for any damages caused by such parties.
Customer shall be responsible for the cost of replacing any security devices
lost or stolen after delivery thereof to Customer. In the event Customer has
reason to believe that an unauthorized party has gained access to the Colocation
Space, Level 3 will, at Customer's request, make video surveillance records of
the colocation area reasonably available to Customer for viewing by Customer in
the presence of a Level 3 employee. In addition, Level 3 will provide Customer
with a copy of the access logs for the colocation area and/or the facility, as
applicable, upon Customer's prior written request.

6. PROHIBITED ACTIVITIES. Customer shall abide by any posted or otherwise
communicated rules relating to use of, access to, or security measures
respecting the facility, colocation area and/or the Colocation Space. Customer's
rights of access and use will be immediately terminated in the event Customer or
any of its agents or employees are in Level 3's Gateway with any firearms,
illegal drugs, alcohol or are engaging in any criminal activity, eavesdropping
or foreign intelligence. Persons found engaging in any such activity or in
possession of the aforementioned prohibited items will be immediately escorted
from the facility.

7. TERMINATION OF USE. Level 3 shall have the right to terminate Customer's use
of the Colocation Space or the Service delivered therein in the event that: (a)
Level 3's rights to use the facility terminates or expires for any reason; (b)
Customer is in default hereof; (c) Customer makes any material alterations to
the Colocation Space without first obtaining the written consent of Level 3; or
(d) Customer allows personnel or contractors to enter the facility, colocation
area and/or the Colocation Space who have not been approved by Level 3 in
advance. With


                                       9
<PAGE>


respect to items (b), (c) and (d), unless (in Level 3's reasonable opinion)
Customer's actions interfere or have the potential to interfere with other Level
3 customers, Level 3 shall provide Customer a written notice and a ten (10) day
opportunity to cure before terminating Customer's rights to the Colocation
Space. With respect to item (a) Level 3 shall promptly provide Customer written
notice upon learning that its rights to use the facility are reasonably likely
to terminate or expire for any reason and shall immediately provide Customer
written notice upon receiving notice that its rights to use the facility have
terminated or expired or will do so.

8. REMOVAL OF EQUIPMENT. Within three (3) days following the expiration or
termination of the Service Term for any Colocation Space, Customer shall remove
all Customer equipment from the Colocation Space. In the event Customer fails to
remove the equipment within such three (3) business day period, Level 3 may
disconnect, remove and dispose of Customer's equipment without prior notice.
Customer shall be responsible for any costs and expenses incurred by Level 3
resulting from Level 3's disconnection, removal, disposal and storage of
Customer's equipment, for which Customer agrees to pay such costs and expenses
and all other charges due and owing by Customer to Level 3 under these Terms
prior to Level 3 returning any Customer equipment still in Level 3's possession.
Level 3 shall not be liable for any loss or damage incurred by Customer arising
out of Level 3's disconnection, removal, storage or disposal of Customer's
equipment.

9. SUBLICENSES. Customer may sublicense the use of Colocation Space under the
following conditions: (a) all proposed sublicensees must be approved, in
writing, by Level 3 in Level 3's sole discretion, except Customer may sublicense
the use of the Colocation Space to an Affiliate of Customer upon prior written
notice to Level 3; (b) Customer hereby guarantees that all such parties shall
abide by the Agreement; (c) Customer shall indemnify, defend and hold Level 3
harmless from all claims brought against Level 3 arising from any act or
omission of any sublicensee or its agents; and (d) any such party shall be
considered Customer's agent and all of its acts and omissions shall be
attributable to Customer for the purposes of this Agreement. In the event
Customer sublicenses use of the Colocation Space without Level 3's prior written
approval, Level 3 may upon ten (10) days' written notice reclaim the sublicensed
portion of the Colocation Space. Customer shall surrender such recaptured
Colocation Space and shall be subject to termination charges associated with the
recaptured Colocation Space as provided in Section 3.5 of the Agreement, plus
reimbursement to Level 3 of the costs incurred by Level 3 in returning the
Colocation Space to a condition suitable for use by third parties. No refunds
shall be made to Customer regarding recaptured Colocation Space.

10. CHANGES.

(A) Level 3 reserves the right to change (at Level 3's cost) the location or
    configuration of the Colocation Space licensed to Customer within the Level
    3 facility; provided that Level 3 shall not arbitrarily require such
    changes. Level 3 and Customer shall work in good faith to minimize any
    disruption in Customer's services that may be caused by such changes in
    location or configuration of the Colocation Space.

(B) Unless otherwise agreed in writing by the parties, in the event any Customer
    Order for Colocation Space is altered (including, without limitation, any
    changes in the configuration or build-out of the Colocation Space) at
    Customer's request after submission and acceptance by Level 3 that results
    in a delay of Level 3's delivery of such Colocation Space to Customer,
    billing for such Colocation Space shall commence no later than the original
    Customer Commit Date.

11. INSURANCE. Prior to storage of equipment or occupancy by Customer and during
the Service Term, Customer shall procure and maintain the following minimum
insurance coverage: (a) Workers' Compensation in compliance with all applicable
statutes of appropriate jurisdiction (including Employer's Liability with limits
of $500,000 each accident); (b) Commercial General Liability with combined
single limits of $1,000,000 each occurrence; and (c) "All Risk" Property
insurance covering all of Customer's personal property located in the Gateway.
Customer acknowledges that it retains the risk of loss for, loss of (including,
without limitation, loss of use), or damage to, Customer equipment and other
personal property located in the Level 3 Gateway. Customer further acknowledges
that Level 3's insurance policies do not provide coverage for Customer's
personal property located in the Level 3 Gateway. Customer shall, at its option,
maintain a program of property insurance or self-insurance covering loss of or
damage to its equipment and other personal property located in the Level 3
Gateway. Customer's Commercial General Liability policy shall be endorsed to
show Level 3 (and any underlying property owner, as requested by Level 3) as an
additional insured. Customer shall waive and/or cause its insurance carriers to
waive all rights of subrogation against Level 3, which will include, without
limitation, an express waiver in all insurance policies. Customer shall furnish
Level 3 with certificates of insurance demonstrating that Customer has obtained
the required insurance coverages prior to use of the Colocation Space or the
storage of equipment in the facility. Such certificates shall contain a
statement that the insurance coverage shall not be materially changed or
cancelled without at least thirty (30) days' prior written notice to Level 3.
Customer shall require any contractor entering the facility on its behalf to
procure and maintain the same types, amounts and coverage extensions as required
of Customer above.

12. REMOTE HANDS. Customer may order and pay for Level 3 to perform certain
limited maintenance services ("Remote Hands") on Customer's equipment within the
Colocation Space, which shall be performed in accordance with Customer's
directions. "Remote Hands" maintenance services includes power cycling
equipment. Level 3 shall in no event be responsible for the repair,
configuration or tuning of equipment, or for installation of Customer's
equipment (although Level 3 will provide reasonable assistance to Customer in
such installation at Customer's request).

13. STORAGE OF CUSTOMER EQUIPMENT. Level 3 may, at its option, agree to store
equipment which Customer intends to colocate in Customer's Colocation Space for
not more than forty-five (45) days prior to the scheduled Colocation Service
Commencement Date. Storage of such equipment is purely incidental to the
Services ordered by Customer and Level 3 will not charge Customer a fee for the
same. No document delivered as part of such storage shall be deemed a warehouse
receipt. Absent Level 3's gross negligence or intentional misconduct, Level 3
shall have no liability to Customer or any third party arising from such
storage. In the event Customer stores equipment for longer than forty-five (45)
days, Level 3 may, but shall not be obligated to, return Customer's equipment to
Customer without liability, at Customer's sole cost and expense.

14. PROMOTIONAL SIGNAGE. Customer may display a single promotional sign with
Customer's name and/or logo on the outside of any Customer private suite
Colocation Space; provided such signage does not exceed 8 inches by 11 inches.

for power provided to any Colocation Space, Level 3 may pass-through to Customer
such price increase upon prior written notice to Customer.

                        (3)LINK(SM) PRIVATE LINE SERVICE
                        --------------------------------

1. SERVICES FROM OTHERS. Where necessary for the interconnection of (3)Link(SM)
Private Line Service with services provided by others, Customer will provide
Level 3 with circuit facility assignment information, firm order commitment
information and the design layout records necessary to enable Level 3 to make
the necessary cross-connection between the (3)Link(SM) Private Line Service and
Customer's designated carrier. Any delay by Customer in providing such
information to Level 3 may delay Level 3's provision of the necessary
cross-connection. Notwithstanding any such delay in the provision of the
cross-connection, billing for the (3)Link(SM) Private Line Service shall
commence on the Service Commencement Date as provided in Section 3.1. Level 3
may charge Customer non-recurring and monthly recurring cross-connect fees to
make such connection, as set forth on Exhibit A to the Agreement.

2. CONNECTION TO CUSTOMER PREMISES.
(A) Where (3)Link(SM) Private Line Service is being terminated Off-Net at the
Customer Premises through an Off-Net Local Loop to be provisioned by Level 3 on
behalf of Customer, the charges set forth in the Customer Order for such Service
assumes that such Service will be terminated at a pre-established demarcation
point or minimum point of entry (MPOE) in the building within which the Customer
Premises is located, as determined by the local access provider. Level 3 may
charge Customer additional non-recurring charges and/or monthly recurring
charges not otherwise set forth in the Customer Order for such Off-Net Service
where the local access provider determines that it is necessary to extend the
demarcation point or MPOE through the provision of additional infrastructure,
cabling, electronics or other materials necessary to reach the Customer
Premises. Level 3 will notify Customer of any additional non-recurring charges
and/or monthly recurring charges as soon as practicable after Level 3 is
notified by the local access provider of the amount of such charges.

(B) In addition, where (3)Link(SM) Private Line Service is being terminated
Off-Net at the Customer Premises through an Off-Net Local Loop to be provisioned
by Level 3 on behalf of the Customer, the charges and the Service Term set forth
in the Customer Order for such Service assumes that such Off-Net Local Loop can
be provisioned by Level 3 through the local access provider selected by Level 3
(and/or Customer) for the stated Service Term. In the event Level 3 is unable to
provision such Off-Net Local Loop through the selected local access provider or
the selected local access provider requires a longer Service Term than that set
forth in the Customer Order, Level 3 reserves the right, regardless of whether
Level 3 has accepted the Customer Order, to suspend provisioning of such Off-Net
Local Loop and notify Customer in writing of any additional non-recurring
charges, monthly recurring charges and/or Service Term that may apply. Upon
receipt of such notice, Customer will have five (5) business days to accept or
reject such changes. If Customer does not respond to Level 3 within the five (5)
business day period, such changes will be deemed rejected by Customer. In the
event Customer rejects the changes (whether affirmatively or through the
expiration of the five (5) business day period), the affected Off-Net Local Loop
will be cancelled without cancellation or termination liability of either party.
