ARTICLE II.                                       CONFIRMATION OF IRU; CONSIDERATION;
                                                  ------------------------------------
                                            OTHER PROVISIONS
                                            ----------------

2.1.              Upon the terms, covenants and conditions contained in this Agreement and subject to the provisions
on conveyance of title to the IRU Fibers and Associated Conduit as set forth in Section 6.2, below, EBS hereby
confirms and recognizes the grant by Backbone to Customer of an exclusive IRU in and to the IRU Fibers, together with
a non-exclusive right of use in the property needed or appropriate for the use of such IRU Fibers as dark fibers,
including, but not limited to, the Associated Conduit, but excluding any electronic or optronic equipment.  EBS
hereby assumes, and agrees that Customer may look to EBS to perform all of, the obligations of the grantor under the
Backbone IRU Agreement and this Agreement, except those excluded provisions as set forth in the Partial Assignment

2.2.              The consideration for the grant herein of the IRU in and to the IRU Fibers shall be (i) Customer's
payment of the IRU Payment (as defined in the Partial Assignment) to Backbone pursuant to the provisions of the

payment to EBS hereunder for the grant of the IRU.

2.3      It is understood and agreed that EBS must and does maintain legal title to the System  subject to the
confirmation of the IRU in this Agreement, until such time as title to the IRU Fibers and Associated Conduit is
conveyed to Customer in accordance with the provisions of Section 6.2, below.  Notwithstanding the foregoing, it is
understood and agreed as between the Parties that the grant of the IRUs by Backbone to Customer shall be treated for
accounting and federal and all applicable state and local tax purposes as the sale and purchase of the IRU Fibers and
the Associated Conduit, and that on or after the exercise of its IRU, Customer shall be treated as the owner of the
IRU Fibers and the Associated Conduit for such purposes.  The Parties agree to file their respective income tax
returns, property tax returns and other returns and reports for their respective Assessments on such basis and,
except as otherwise required by law, not to take any positions inconsistent therewith.  Notwithstanding the
foregoing, however, in the event that Customer's independent auditors advise Customer that Customer is not permitted
to report this transaction as a purchase and sale, then Customer may report in accordance with its auditor's advice;
provided, that Customer shall provide prompt written notice to EBS of the reasons for such auditor's conclusions.
2.4      This Agreement amends and restates the Backbone IRU Agreement in its entirety, as it applies to the IRU
Fibers, and Customer shall have no further obligations or liabilities thereunder.  This Agreement does not amend or
restate the Partial Assignment, which continues in full force and effect according to its terms.  Customer retains
whatever rights it may have against LJM2 and/or Backbone pursuant to the Partial Assignment.

ARTICLE III.                                    CONNECTION TO THE SYSTEM AND COLLOCATION
                                                ----------------------------------------

3.1.              The IRU Fibers will be terminated at an EBS fiber optic patch panel in the same general space as

will not be unreasonably withheld or delayed; provided, however, any connection requiring a splice to be entered
                                              --------  -------
shall be performed by EBS at Customer's sole expense.  In order to schedule a connection through a splice point,
Customer shall coordinate the work at least thirty (30) days in advance of the date the connection is requested to be
completed.  EBS shall use commercially reasonable efforts to accommodate the request.  Such work shall be restricted
to the planned system work period set forth in Exhibit E to this Agreement unless otherwise agreed to in writing.
                                               ---------
Notwithstanding the above, EBS may prohibit Customer from making a connection at any Connecting Point if EBS can
demonstrate to Customer reasonable satisfaction that use of a proposed Connecting Point would materially and
adversely affect the System.

3.2.              Customer shall not employ equipment or technologies that will interfere with the use of any of the
fibers in the System or damage the IRU Fibers or any other fibers in the System.

3.3.              As more particularly indicated on Exhibit A, EBS will provide spacing of not more than fifty (50)
miles between Transmission Sites, except where geographic factors require different spacing. The Parties shall
execute, contemporaneous with the execution of this Agreement, a Collocation Agreement substantially in the form of
Exhibit F, under which agreement EBS will provide collocate space to Customer at such sites as are set forth in such
---------
Collocation Agreement.  The collocate space will be 300 square feet at each regenerator station and 100 square feet
at each optical amplifier site unless otherwise agreed in the Collocation Agreement.  EBS will provide such
collocation space as provided in and pursuant to the terms and conditions of such Collocation Agreement.  In
addition, EBS will accommodate Customer on a non-discriminatory basis at EBS point of presence locations as space is
available, at EBS standard rates and in accordance with EBS' standard terms and conditions.  Upon conveyance of title
to the IRU Fibers and Associated Conduit to Customer in accordance with the provisions of Section 6.2, below, EBS
will continue to provide such collocate space and services to Customer so long as there remains in place a valid
Collocation Agreement substantially in the form of Exhibit F.
                                                   ---------

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

6.1.              This Agreement shall have a term (the "Term") that begins on the Effective Date and shall remain
effective until the end of the Initial Term (as defined in the next sentence), or, if applicable, the end of the last
renewal of the Initial Term.  The initial term ("Initial Term") of the grant of the IRU in and to the IRU Fibers
shall begin on the Effective Date and shall end on June 30, 2020.  Subject to the conditions and limitations set
forth below, and subject to the extension of the EBS Required Rights, Customer may, by written notice, extend the IRU
grant and this Agreement for an additional ten (10) year period or such shorter period as required by the EBS
Required Rights, and, if it has so elected to so extend, it may, by written notice, extend the IRU grant and this
Agreement for a second ten (10) year period or such shorter period as required by the EBS Required Rights.  Customer
shall provide such written notice at least one (1) year in advance of the date the Initial Term or the extension
thereof would expire absent such notice.  Within thirty (30) days after the date on which EBS has received Customer's
written notice electing to extend the term of this IRU and requesting a report on the remaining term of the EBS
Required Rights, EBS will advise Customer of the remaining term of all applicable EBS Required Rights.  If such EBS
Required Rights do not extend for the entire length of the extended term, Customer shall have the right to (i) extend
this Agreement for the entire renewal term or for a term shorter than the renewal term (but in either of such events
Customer, prior to such renewal term, shall obtain renewals of such EBS Required Rights, in Customer's name, at
Customer's sole cost, or, at EBS' option, in Customer's and EBS' names, in which latter case Customer and EBS shall
share the costs, with EBS paying the costs attributable to all IRU holders in the same Cable who claim through EBS
(except Customer and its assignees) or (ii) withdraw its election to extend the term of this Agreement.  Subject only
to the charges for the Basic Maintenance Services as provided in Article VII, any extension of this Agreement shall
be on the same terms and conditions as contained in this Agreement and for no additional consideration.  Customer
shall have the right (but not the obligation) to extend or obtain modification of any EBS Required Right, on
Customer's own behalf and at its sole cost, to the extent Customer deems appropriate in connection with any extension
of the Term. Customer may not extend this Agreement if, at least six (6) months prior to the date of the proposed
extension, EBS, based on its reasonable opinion, notifies Customer that it is not commercially practicable tocontinue
operation or maintenance of the System beyond the Initial Term or beyond the first extension, as applicable.

         6.2      Subject to the extension rights described above, upon the expiration of the Term of this Agreement
EBS shall convey title to the IRU Fibers and Associated Conduit to Customer pursuant to a bill of sale substantially
in the form of Exhibit G hereto.  Upon such conveyance the IRU in the IRU Fibers shall immediately terminate and all
               ---------
rights of Customer pursuant to this Agreement shall cease and, except as provided in Section 6.3, below, neither
Party shall owe the other any additional duties or consideration hereunder.  Unless EBS and Customer shall have
entered into an Operation, Maintenance and Repair Agreement substantially in the form of Exhibit H, Customer shall,
                                                                                         ---------
within sixty (60) days after the end of the Term (unless the Parties agree to a longer period), remove all
electronics and equipment from the System , including any EBS facilities, at Customer's sole cost, under EBS'
supervision.  In the event of failure of Customer to remove same within said period, EBS shall remove same at
Customer's sole expense, to be reimbursed by Customer within thirty (30) days of receipt of EBS' invoice therefor.  In
order for the equipment or facilities of Customer to be or remain connected  to the System, Customer and EBS must
have entered into an Operation Maintenance and Repair Agreement substantially in the form of Exhibit H.
                                                                                             ---------

6.3      Notwithstanding the foregoing, no termination of this Agreement shall affect the rights or obligations of
any Party hereto with respect to (a) any payment hereunder for services rendered prior to the date of termination, or
(b) pursuant to Article XI, Article XII, Article XIII, Article XVI, Section 17.4 and Article XIX of this Agreement.

6.4      During any extension of this Agreement as provided in this Article VI, Customer shall pay EBS its
proportionate share of any recurring fees charged pursuant to the EBS Required Rights.  Customer's proportionate
share will be based upon the number of fibers in which it has an IRU and the total number of fibers in the System.
EBS will advise Customer of the amount of such fees, within one hundred and twenty (120) days after Customer's
election to renew the Term of the Agreement, and within thirty (30) days thereafter Customer may elect to withdraw
its renewal of the Term.

Customer will be billed for Basic Maintenance Services at a rate of $"*" per Actual Route Mile per year, prorated
to accommodate any partial year during the term of this Agreement, and adjusted annually to reflect annual changes in
the U.S. Producer Price Index (Bureau of Labor Standards "All Finished Goods" Series ID WPUSOP3000); provided that in
                                                                                                     --------
no event shall the rate be less than $"*" per Actual Route Mile per year.  Customer shall pay EBS' annual invoice
for Basic Maintenance Services within thirty (30) days after receipt of invoice.  Late payments of such amounts shall

System or the IRU Fibers caused by Customer's negligence or willful misconduct or elective maintenance or repair
requests.  EBS shall not perform nor be responsible for any maintenance or repair of any of Customer's equipment.

7.3.              EBS may subcontract for maintenance and restoration services hereunder including Basic Maintenance
services.  All such subcontractors shall perform their work in accordance with the applicable specifications
contained in this Agreement and Exhibits C and E attached hereto, and then-prevailing industry standards.   No such
                                ----------------
subcontracting shall relieve EBS of its obligations hereunder.

7.4.              Upon notification from Customer of any Service Interruption, EBS shall promptly begin to mobilize
crews and make its best effort to achieve necessary repairs or restoration, in accordance with the procedures set
forth in Exhibit E.  For purposes hereof, "best efforts" means activities and performance consistent with prudent
         ---------
industry practice, and response times that do not jeopardize the health and safety of employees or agents of EBS or
Customer.

7.5.              EBS shall use a degree of care in performing repair and maintenance pursuant to this Agreement that
equals or exceeds that which is normal and customary in the communications industry, and complies with the standards
set forth in Exhibit E, attached hereto and incorporated herein.

7.6.              In the event Customer notifies EBS, or EBS otherwise becomes aware, of a need for repair to the
System, or of damage to the System that results from a specific accident or disaster, or deterioration of the IRU
Fibers in the System requiring replacement of IRU Fibers ("Damage or Deterioration"), EBS, at its cost, shall
promptly repair such Damage or Deterioration using its best efforts as defined in Section 7.4 above.  However, if the
Damage or Deterioration is due to the negligence or willful misconduct of EBS or Customer, the party responsible for
such Damage or Deterioration shall be responsible for the costs of repairing the System to the extent the Damage or
Deterioration was caused by  such party.  EBS and Customer shall reasonably cooperate with each other to collect any
available insurance proceeds or other recoverable amounts and to resolve any disputes with insurance carriers
regarding the availability of insurance proceeds to repair any Damage or Deterioration to the System.  To the extent
any costs are recovered from a third party not having an interest in the fibers in the Cable, or, in the case of a
third person's having an interest in the cable, costs in excess of such third person's proportionate share in the
cable, Customer's share of such costs, if any, shall be reduced proportionately.

7.7.              To the extent that repair of Damage or Deterioration (not caused by the negligence or willful
misconduct of EBS or Customer or another person with an interest in the System) exceeds Basic Maintenance Services,
EBS and Customer shall exert good-faith efforts to minimize the costs to repair such Damage or Deterioration, as
follows:  (i) EBS shall attempt to recover such costs from any third persons who may be responsible therefor, and
(ii) in the event EBS is not completely successful in that effort, Customer may attempt to recover any such costs not
recovered by EBS.  Customer shall pay EBS' invoice for Customer's Proportionate Share (as hereinafter defined) of the
cost to repair the Damage or Deterioration, within thirty (30) days after receipt of the invoice.  The Parties shall
adjust Customer's payment of such costs to EBS by the amount, if any, recovered by Customer.  Upon request by one
Party, the other Party shall promptly provide the necessary substantiating information that will allow the first
Party to verify the accuracy of the invoice.  For purposes hereof, all costs in excess of Basic Maintenance shall be
allocated equally across all the conduits in the affected segment of the System, and then, with respect to a conduit,
equally among the fibers (whether sold or unsold, dark or lit) in such conduit.  Customer's "Proportionate Share"
shall be the costs allocated to its individual fibers in such manner.

7.8.              In the event this Agreement is extended as provided in Article VI, EBS will continue to provide the
Basic Maintenance Services for each extension at EBS' then current rates.

ARTICLE VIII.                                          PERMITS AND REQUIRED RIGHTS
                                                       ---------------------------

8.1.     EBS has obtained all R of W Agreements as well as any other licenses, permits, franchises, easements, rights
obtained to perfect easements or other property rights for telecommunications purposes, authorizations (including any
necessary state, tribal or federal authorizations such as environmental permits), indefeasible rights of use, leases
and other agreements necessary for (i) the installation and operation of the System  hereunder, and (ii) the grant of
the IRU to LJM2, to Backbone, and to Customer, and (iii) the use and operation of the IRU Fibers by Customer (all of
which interests are referred to as "EBS Required Rights").

8.2.     EBS shall cause all EBS Required Rights to remain effective through the Initial Term.

8.3.     EBS' obligation to maintain the EBS Required Rights as provided above shall cease upon the expiration of the
Initial Term.  After such cessation, Customer shall be responsible for obtaining any permits, easements, and other
right of way-related documents relating to Customer's fibers and interest in the Associated Conduit.

8.4.     In the event that, during the Initial Term, EBS receives notice that it has not obtained a necessary EBS
Required Right, or that an EBS Required Right is or may be defective, EBS will promptly so notify Customer, in
writing, and will promptly take such steps as it reasonably deems appropriate to confirm the integrity of the EBS
Required Right, acquire an additional EBS Required Right, or take such other action as may be appropriate to protect
Customer's rights to exercise its rights hereunder.  Notwithstanding the foregoing, if Customer becomes aware that a
failure of defect in an EBS Required Right poses a threat to Customer's continued ability to execise its rights
hereunder, including, without limitation, a threat of injunction threatening Customer's right to operate the System,
Customer shall immediately so notify EBS in writing and allow EBS a reasonable opportunity to confirm the integrity
of the EBS Required Right; provided, that in the event EBS cannot or will not do so within a reasonable time given
the circumstances, Customer, upon providing written notice thereof to EBS, may take such action that it deems
appropriate to ensure its continuing right to exercise its rights hereunder, and EBS shall reimburse Customer on
demand for all Customer's reasonable costs and expenses incurred in doing so.

ARTICLE IX.                                                    RELOCATION
                                                               ----------

If, following the Effective Date, EBS is required to relocate the Cable or any of the facilities used or required in
providing Customer with the IRU, EBS shall give Customer sixty (60) days prior notice of any such relocation, if
possible, and shall proceed with such relocation.  EBS shall have the right to direct such relocation, including, but
not limited to, the right to determine the extent of, the timing of, and methods to be used for such relocation;
provided that any such relocation: (a) shall be constructed and tested in accordance with the specifications and
--------
requirements set forth in Exhibits A and C; (b) shall not result in a materially adverse change to the operations,
                          ----------------
performance, Connecting Points with the network of Customer, or end points of the System; and (c) shall not
unreasonably interrupt service on the System.  If the relocation is required due to EBS' failure to maintain an EBS
Required Right, EBS shall pay the Relocation Costs.  In all other circumstances, where the Relocation Cost (excluding
reimbursements) of EBS' relocation exceeds $"*" per occurrence and is beyond the reasonable control of EBS,
Customer shall reimburse EBS for Customer's Proportionate Share of the Relocation Costs (including, without
limitation, fiber acquisition, splicing and testing).   In the event that a third party that does not have an
interest in the fibers in the Cable reimburses EBS for all of or a portion of the cost to relocate the System, or a
third person with an interest in the Cable reimburses EBS for more than its Proportionate Share of such Relocation
Costs, then reimbursement amount shall reduce on a dollar-for-dollar basis the aggregate amount of Relocation Costs
deemed to have been spent by EBS under this Article IX.  EBS shall deliver to Customer updated as-built drawings
consistent with the specifications set forth in Exhibit D with respect to any relocated portion of the System  no
                                                ---------
later than ninety (90) days following completion of the work.  EBS shall prepare a budget for the costs associated
with such relocation and, except in the event of an emergency, at least thirty (30) days prior to beginning such
relocation work provide Customer a copy.  EBS shall provide information and documentation to Customer sufficient to
demonstrate the basis for and the proportionate amount of the Relocation Costs chargeable to Customer.  Customer
shall pay Customer's proportionate share of such Relocation Costs within thirty (30) days of receipt of the foregoing
information

ARTICLE X.                                                  USE OF THE SYSTEM
                                                            -----------------

10.1.    Customer warrants that its use of the IRU Fibers and the System shall comply in all material respects with
applicable government codes, ordinances, laws, rules, regulations and restrictions and shall not have an adverse
effect on the System or its use.

10.2.    Customer may use the IRU Fibers for any lawful purpose.  EBS agrees and acknowledges that EBS has no right
to use the IRU Fibers during the Term.

10.3.    EBS and Customer shall promptly notify each other of any matters pertaining to any damage or impending
damage to or loss of the System or any part thereof, that are known to such Party and that could reasonably be
expected to affect the System.

10.4.    Customer shall take all reasonable precautions against, and shall assume liability, subject to the terms of
this Agreement, for any damage caused by Customer to the fibers used or owned by EBS or third parties.  EBS shall
take all reasonable precautions against, and shall assume liability, subject to the terms of this Agreement, for any
damage caused by EBS to the IRU Fibers or to fibers or other portions of the System used or owned by third parties.

10.5.    Customer shall not use the IRU Fibers or any portion of the System  in a manner that interferes in any way
with or adversely affects the use of the fibers of EBS or third parties within the System or their respective
equipment and facilities associated with the Cable or their use of any portion of the System.  EBS shall not use and
shall prohibit third parties from using the System or any part of the System in a manner that interferes in any way
with or adversely affects Customer's use of the IRU Fibers or Customer's equipment and facilities associated with the
IRU Fibers.

10.6.    EBS and Customer each agree to cooperate with and support the other in complying with any requirements
directly applicable to the IRU Fibers by any governmental or regulatory agency or authority.

ARTICLE XI.                                                  INDEMNIFICATION
                                                             ---------------

11.1.    Subject to the provisions of Section 17.3, Customer hereby releases and agrees to indemnify, defend, protect
and hold harmless EBS, its Affiliates, and its and their employees, officers, directors, agents, contractors, and
shareholders ("Indemnified Persons"), from and against any third party claims, suits, proceedings and actions
("Claims") for:

11.1.1.  Any injury, death, loss or damage to any person, tangible property or facilities of any person or entity
                  (including reasonable attorney fees and costs at trial and appeal) to the extent arising out of or
                  resulting from the acts or omissions, negligent or otherwise, of Customer, its officers, directors,
                  employees, agents or contractors in connection with its performance or non-performance under this
                  Agreement;

11.1.2.  Any liabilities or damages (including reasonable attorney fees and costs at trial and appeal) arising out of
                  any violation by Customer of regulations, rules, statutes or court orders of any local, state or
                  federal governmental agency, court or body in connection with its performance under this Agreement;
                  and

11.1.3.  Any liabilities or damages asserted by Customer's telecommunications clients and arising directly or
                  indirectly from any outages, disruptions or interruptions of service in the operation of Customer's
                  IRU Fibers or any failure of such fibers to transmit accurately any message.

11.2.    Subject to the provisions of Section 17.3, EBS hereby releases and agrees to indemnify, defend, protect and
hold harmless Customer and its Indemnified Persons from and against any third party Claims for:

11.2.1.  Any injury, death, loss or damage to any person, tangible property or facilities of any person or entity
                  (including reasonable attorney fees and costs at trial and appeal), to the extent arising out of or
                  resulting from the acts or omissions, negligent or otherwise, of EBS, its officers, directors,
                  employees, agents or contractors in connection with its performance or non-performance under this
                  Agreement;

11.2.2.  Any liabilities or damages (including reasonable attorney fees and costs at trial and appeal) arising out of
                  any violation by EBS of regulations, rules, statutes or court orders of any local, state or federal
                  governmental agency, court or body in connection with its performance under this Agreement; and

11.2.3.  Any failure by EBS to obtain and/or maintain, throughout the Initial Term, all EBS Required Rights
                  reasonably necessary or appropriate to permit Customer to use and enjoy the IRU Fibers, Associated
                  Conduit, and Transmission Sites, as provided herein.  Customer shall be permitted to participate in
                  any such defense at its sole cost and expense, provided it conducts such participation in a manner
                  that does not interfere with EBS' defense.

11.3.    EBS and Customer hereby expressly recognize and agree that each Party's obligation to indemnify, defend,
protect and save harmless Indemnified Persons is a material obligation to the continuing performance of the Parties'
other obligations, if any, hereunder.  However, in the event that either EBS or Customer fails for any reason to so
indemnify, defend, protect and save harmless, the injured Party's sole remedy in such event shall be the right to
bring an arbitration proceeding pursuant to the terms of this Agreement against the other for damages as a result of
such failure to indemnify, defend, protect and save harmless.  The obligations of this Section 11.3 shall survive the
expiration or earlier termination of this Agreement.  EBS and Customer each affirmatively state and warrant to the
other that its indemnity obligation as to property damage or personal injury will be supported by liability insurance
to be furnished by it; provided that recovery under or in respect of this indemnity shall not be limited to the
                       --------
proceeds of any such insurance.

11.4.    Nothing contained herein shall operate as a limitation on the right of either EBS or Customer to bring an
action for damages against any third party, including indirect, special, or consequential damages, based on any acts
or omissions of such third party as such acts or omissions may affect the construction, operation or use of the IRU
Fibers or the System or any portion thereof; provided, however, the above limitation of liability shall apply to
                                             --------  -------
indirect liability including Claims against third parties who, directly or through one or more other parties, have a
right of indemnification, impleader, cross-claim, contribution or other right of recovery against a Party to this
Agreement.  Each of EBS and Customer shall assign such rights or claims, execute such documents and do whatever else
may be reasonably necessary to enable the other to pursue any such action against such third party.

ARTICLE XII.                                                    INSURANCE
                                                                ---------

                  limits of $1,000,000 each accident.

12.1.3.  Automobile Liability Insurance with a combined single limit of $2,000,000 for bodily injury and property
                  damage, to include coverage for all owned, non-owned and hired vehicles.

The limits set forth above are minimum limits and shall not be construed to limit the liability of either Party.

12.2.    EBS' insurance policies required above shall be obtained and maintained with companies rated A- or better by
Best's Key Rating Guide; provided however that all or part of the Commercial General Liability Insurance provided by
                         -------- -------
EBS may be provided through a self-insurance program of Enron Corp., EBS' ultimate parent corporation.  All such
insurance or self-insurance shall, to the extent of EBS' indemnity obligations under this Agreement, be primary to
any other available coverage.  Upon request, EBS shall provide Customer with an insurance certificate confirming
compliance with the insurance requirements of this Article XII.  The insurance certificate shall indicate that
Customer shall be notified not less than thirty (30) days prior to any cancellation or material change in coverage.

12.3.    Unless otherwise agreed, Customer's insurance policies required above shall be obtained and maintained with
companies rated A- or better by Best's Key Rating Guide; provided however, that upon approval of EBS, which approval
                                                         -------- -------
will not be unreasonably withheld or delayed, all or part of the Commercial General Liability Insurance to be
provided by Customer may be provided through a self-insurance program of Customer or the ultimate parent corporation
of Customer.  All such insurance or self-insurance shall, to the extent of Customer's indemnity obligation contained
in this Agreement, be primary to any other available coverage. Customer shall provide EBS with an insurance
certificate confirming compliance with the insurance requirements in this Article XII.  The insurance certificate
shall indicate that EBS shall be notified not less than thirty (30) days prior to any cancellation or material change
in coverage.

12.4.    In the event coverage is denied or reimbursement of a properly presented claim is disputed by the carrier
for insurance provided above, the Party carrying such coverage shall make commercially reasonable efforts to pursue
such claim with its carrier.

12.5.    The Parties shall each obtain from the insurance companies providing the coverage required by this Agreement
a waiver of all rights of subrogation or recovery in favor of the other Party and, as applicable, its parent
corporation, shareholders, affiliates, subsidiaries, assignees, officers, directors, and employees or any other party
entitled to indemnity under this Agreement.

ARTICLE XIII.                                 TAXES AND FRANCHISE; LICENSE AND PERMIT FEES
                                              --------------------------------------------

13.1.    Subject to Section 13.2 below, Customer shall be responsible for and pay to any taxing authority any and all
sales, use, income, gross receipts, excise, transfer, ad valorem or other taxes, and any and all franchise fees or
similar fees ("Assessments") (excluding income taxes (or gross receipts taxes in lieu of income taxes) of EBS
resulting from this transaction), assessed against Customer due to (i) its ownership (consistent with Section 2.3) of
an IRU, (ii) its use of the IRU Fibers, including the providing of services over the IRU Fibers, (iii) its lease or
use of any portion of the System, (iv) its ownership, lease or use of facilities connected to the IRU Fibers, or (v)
the sale to Customer of the IRU Fibers and the Associated Conduit.

13.2.    Subject to Section 13.1 above, EBS shall be responsible for and pay to any taxing authority any and all
Assessments assessed against it due to its construction, ownership (consistent with Section 2.3) or use of the
System, including providing services over the System, or its ownership or use of facilities connected to the System.

13.3.    In the event that EBS is assessed for any Assessments related to Customer's ownership of an IRU or
Customer's use of the IRU Fibers or any portion of the System which may not feasibly be separately assessed, EBS,
within thirty (30) days of receipt of an invoice therefor, shall provide information and documentation to Customer
sufficient to demonstrate the basis for the Assessments and the amount and due date for payment of the Assessments.
In addition, EBS shall provide Customer with all information reasonably requested by Customer with respect to any
such Assessments.  After such thirty (30) day period, EBS, in it sole discretion, may pay such Assessment and invoice
Customer for reimbursement, provided that EBS will not pay such Assessment if Customer objects and bonds or otherwise
takes action such that EBS' failure to pay such Assessment will not result in a lien on any portion of the System or
result in any forfeiture of title. If Customer does not object and EBS makes such payment, Customer shall reimburse
EBS for such payment within ten (10) days of receipt of EBS' invoice.  Notwithstanding such payment by EBS, Customer,
at its option, shall have the right at its sole cost to contest any such Assessments and EBS will reasonably
cooperate with Customer in pursuing any such contest; provided that Customer shall have reimbursed EBS for such
                                                      --------
Assessments.  In the event EBS, in its sole discretion, elects to not pay such Assessment, it shall so notify
Customer.  Customer, at its option, may pay the Assessments, or contest the payment; provided, that such contest
                                                                                     --------
shall be resolved or such Assessments shall be paid so as to prevent any forfeiture of rights or property or the
imposition of any lien on the System.

ARTICLE XIV.                                                SYSTEM WARRANTIES
                                                            -----------------

14.1.    Beginning on the Effective Date, and ending twelve months thereafter, EBS shall warrant that the IRU Fibers
shall comply with all applicable specifications set forth in this Agreement.  If, within such warranty period,
Customer discovers that the IRU Fibers do not so comply, Customer shall provide written notice of such fact to EBS,
and within fifteen (15) days of receipt of written notice of such defect, EBS shall inspect such IRU Fibers and
promptly thereafter, at no cost to Customer, correct any such defect or notify Customer of EBS' disagreement as to
any defects recited in Customer's notice.  EXCEPT AS OTHERWISE SPECIFICALLY SET FORTH IN THIS SECTION OR THE
REPRESENTATIONS, WARRANTIES, COVENANTS AND CONDITIONS OF THIS AGREEMENT, EBS MAKES NO WARRANTY TO CUSTOMER OR ANY
OTHER PERSON OR ENTITY, WHETHER EXPRESS, IMPLIED OR STATUTORY, AS TO THE INSTALLATION, DESCRIPTION, QUALITY,
MERCHANTABILITY, COMPLETENESS OR FITNESS FOR ANY PURPOSE OF THE CABLE OR ANY FIBERS OR ANY SERVICE OR FACILITY
PROVIDED HEREUNDER OR DESCRIBED HEREIN, OR AS TO ANY OTHER MATTER, ALL OF WHICH WARRANTIES ARE HEREBY EXCLUDED AND
DISCLAIMED.

14.2.    Customer's sole and exclusive remedy for breach of the foregoing warranty shall be repair and replacement,
at EBS' expense, of the portion of the IRU Fibers found to be defective.  In no event shall EBS be liable to Customer
for any indirect, exemplary, special or consequential damages, including but not limited to lost profits or the cost
of providing or obtaining alternative service.

14.3.    In procuring and obtaining materials for the installation of the System, EBS has used reasonable efforts to
obtain from the vendors and suppliers thereof, for the mutual benefit of Customer and EBS, warranties that such
materials are:  (a) of the kind and quality described in the purchase order or supply contract; (b) free of defects
in workmanship, material, design and title; (c) of good and merchantable quality; and (d) where appropriate, fit for
their intended purpose.  In addition, EBS has attempted to obtain standard warranty periods for all System materials,
and shall use reasonable efforts to obtain longer warranty periods, if such extended warranties do not materially
increase the cost of such materials.  In no event shall EBS be deemed to have guaranteed to procure any such
warranties or to guarantee such warranties as were procured from vendors or suppliers. Without in any way limiting
Section 14.1 above, or this Section 14.2, to the extent that any manufacturer's warranties can be lawfully assigned
or otherwise made available to Customer, EBS will (provided it is without detriment to EBS' rights under or with
                                                   --------
respect to such warranties) cooperate and assist Customer, at Customer's sole cost and expense, with respect to any
claim that Customer may assert against the manufacturer under such warranties, including such reasonable actions as
may be necessary to assign or otherwise make available to Customer the right to make such claims.

14.4.    In the event any maintenance or repairs to the System  are required as a result of a breach of any warranty
made by any manufacturer, contractor or vendor, EBS shall pursue any remedies it may have against such manufacturer,
contractor or vendor, and EBS shall reimburse Customer for any maintenance or repair costs that Customer has incurred
as a result of any such breach of warranty to the extent the manufacturer, contractor or vendor has paid such costs;
provided that:  (a) EBS shall be entitled to reduce such amount recovered from the manufacturer, contractor or vendor
--------
by legal and collection costs incurred; and (b) EBS shall have the right to prorate such amount so recovered (as so
reduced) among Customer, itself and other parties, based on IRU or fiber ownership.

ARTICLE XVI.                                                 CONFIDENTIALITY
                                                             ---------------

16.1.    If the Parties have entered into (or later enter into) a confidentiality agreement, the terms of such an
agreement shall control and Section 16.2 below shall not apply; provided, however, that if any such confidentiality
                                                                --------  -------
agreement expires or is no longer effective at any time when this Agreement is effective, Section 16.2 below shall be
in effect for such periods.

16.2.    In the absence of a separate confidentiality agreement between the Parties, if either Party provides
confidential information to the other in writing and identified as such or if in the course of performing under this
Agreement a Party learns confidential information regarding the facilities or plans of the other, the receiving Party
shall protect the confidential information from disclosure to third parties with the same degree of care accorded its
own confidential and proprietary information; provided, however, that the Parties shall each be entitled to provide
                                              --------  -------
such confidential information to their respective directors, officers, members, managers, employees, agents, and
contractors ("Representatives"), entities controlling, controlled by or under common control with ("Affiliates") EBS
or Customer respectively, or the Representatives of such Affiliates, in each case whose access is reasonably
necessary.  Each such recipient of confidential information shall be informed by the Party disclosing confidential
information of its confidential nature, and shall be directed to treat such information confidentially and shall
agree to abide by these provisions.  In any event, each Party shall be responsible for any breach of this provision
by any person to whom that Party discloses confidential information.  Neither EBS nor Customer shall be required to
hold confidential any information that:  (a) becomes publicly available other than through the recipient; (b) is
independently developed by the disclosing Party; or (c) becomes available to the disclosing Party without restriction
from a third party.  These obligations shall survive expiration or termination of this Agreement for a period of two
(2) years.

16.3.    Notwithstanding Sections 16.1 and 16.2 above, confidential information shall not include information
disclosed by the receiving Party as required by applicable law or regulation; provided, however, that the information
                                                                              --------  -------
disclosed is limited to the existence and general nature of the relationship between EBS and Customer, including, as
required, the scope, approximate revenues, purposes and expectations related to such relationship and a description
of any disputes relating thereto and the disclosing Party uses reasonable efforts to provide the other Party with
written notice of such potential disclosure, prevent such disclosure, and provide the other Party with a reasonable
opportunity to secure the confidential protections thereof.  Notwithstanding the foregoing, this Agreement may be
provided to any governmental agency or court of competent jurisdiction to the extent required by applicable law.

16.4.    Neither Party shall use the name, tradename, servicemark or trademark of the other, nor issue any press
releases regarding this Agreement or the terms and conditions of this Agreement or use the other Party's name in any
promotional or advertising material without the prior written consent of such Party.

ARTICLE XVII.                                       DEFAULT; LIMITATION OF LIABILITY
                                                    --------------------------------

17.1     EBS shall not be in default under this Agreement unless and until Customer shall have given EBS written
notice of such default and, in the case of defaults other than a failure to respond to service-affecting situations
as set forth in Exhibit E, EBS shall have failed to cure the same within thirty (30) days after receipt of such
notice; provided, however, that where such default cannot reasonably be cured within such thirty (30) day period, if
        --------  -------
EBS shall proceed promptly to cure the same and prosecute such curing with due diligence, the time for curing such
default shall be extended for a period as long as necessary to effect such cure; provided, further, that failure to
pay any amounts due hereunder shall be a default if not cured within ten (10) days after written notice specifying
such failure.  Events of default shall include, but not be limited to: (a) the breach by EBS of any material term,
covenant or condition of this Agreement; (b) the making by EBS of a general assignment for the benefit of its
creditors; (c) the filing of a voluntary petition in bankruptcy or the filing of a petition in bankruptcy or other
insolvency protection against EBS that is not dismissed within ninety (90) days thereafter; (d) the filing by EBS of
any petition or answer seeking, consenting to, or acquiescing in reorganization, arrangement, adjustment,
composition, liquidation, dissolution or similar relief, or (e) the failure of EBS to pay any sums owing by EBS to
Customer.  Any event of default by EBS may be waived under the terms of this Agreement at Customer's option, but no
default by EBS shall be deemed waived by Customer unless such waiver is evidenced by a written document executed by
Customer.  Upon the failure by EBS to timely cure any such default after notice thereof from Customer, Customer may:
(i) take such action as Customer determines, in its sole discretion, to be necessary to correct the default; and (ii)
subject to Section 17.3 below and the provisions of Article XIX of this Agreement, pursue any legal remedies it may
have under applicable law or principles of equity relating to such breach.  Notwithstanding the above, if EBS
certifies to Customer in writing that a default has been cured, such default shall be deemed to be cured unless
Customer otherwise notifies EBS in writing within fifteen (15) days of receipt of such notice from EBS; provided,
                                                                                                        --------
however, that this provision shall not apply to a default with respect to the payment of money.
--------

17.2     With respect to any breach or failure to perform by Customer under this Agreement, Customer shall not be in
default under this Agreement unless and until EBS shall have given Customer written notice of such default and
Customer shall have failed to cure the same within thirty (30) days after receipt of such notice; provided, however,
                                                                                                  --------  -------
that where such default cannot reasonably be cured within such thirty (30) day period, if Customer shall proceed
promptly to cure the same and prosecute such curing with due diligence, the time for curing such default shall be
extended for a period as long as necessary to cure such default; provided, further, that failure to pay any amounts
due hereunder shall be a default if not cured within ten (10) days after written notice specifying such failure; and
provided, further, that no cure period shall be permitted in connection with a default that materially interferes
with service on the System or otherwise materially and adversely affects the integrity of the System.  Events of
default shall include, but not be limited to:  (a) the breach by Customer of any material term, covenant or condition
of this Agreement; (b) the making by Customer of a general assignment for the benefit of its creditors; (c) the
filing of a voluntary petition in bankruptcy or the filing of a petition in bankruptcy or other insolvency protection
against Customer that is not dismissed within ninety (90) days thereafter; (d) the filing by Customer of any petition
or answer seeking, consenting to, or acquiescing in reorganization, arrangement, adjustment, composition,
liquidation, dissolution or similar relief; or (e) the failure of Customer to pay any sums owing by Customer to EBS.
Any event of default by Customer may be waived under the terms of this Agreement at EBS' option, but no default by
Customer shall be deemed waived by EBS unless such waiver is evidenced by a written document executed by EBS.  Upon
the failure by Customer to timely cure any such default after notice thereof from EBS, EBS may:  (i) take such action
as it determines, in its sole discretion, to be necessary to correct the default; and (ii) subject to Section 17.3
and the provisions of Article XIX of this Agreement, pursue any legal remedies it may have under applicable law or
principles of equity relating to such breach. Notwithstanding the above, if Customer certifies to EBS in writing that
a default has been cured, such default shall be deemed to be cured unless EBS otherwise notifies Customer in writing
within fifteen (15) days of receipt of such notice from Customer; provided, however, that this provision shall not
                                                                  --------  --------
apply to a default with respect to the payment of money.

17.3     NEITHER PARTY SHALL BE LIABLE FOR SPECIAL, PUNITIVE, EXEMPLARY, CONSEQUENTIAL, INCIDENTAL OR INDIRECT LOSSES
OR DAMAGES AS A RESULT OF THE PERFORMANCE OR NONPERFORMANCE OF ITS OBLIGATIONS UNDER THIS AGREEMENT, OR ITS ACTS OR
OMISSIONS RELATED TO THIS AGREEMENT, WHETHER OR NOT ARISING FROM SOLE, JOINT OR CONCURRENT NEGLIGENCE OR STRICT
LIABILITY OR OTHERWISE.  THE ABOVE LIMITATION OF LIABILITY SHALL APPLY TO INDIRECT LIABILITY INVOLVING SUITS BROUGHT
AGAINST THIRD PARTIES WHO, DIRECTLY OR THROUGH ONE OR MORE OTHER PARTIES, HAVE A RIGHT OF INDEMNIFICATION, IMPLEADER,
CROSS-CLAIM, CONTRIBUTION, OR OTHER RIGHT OF RECOVERY AGAINST A PARTY TO THIS AGREEMENT (e.g., if an affiliate of
Party A sues Party B's contractor under circumstances in which the contractor has a right of indemnity against Party
B).

17.4     In the event either EBS or Customer fails to make any payment under this Agreement when due, such amounts
shall accrue interest, from the date such payment is due until paid, including accrued interest, at a rate (unless
specifically described elsewhere in this Agreement) equal to twelve (12%) per annum or, if lower, the highest
percentage allowed by law.

ARTICLE XVIII.                                                FORCE MAJEURE
                                                              -------------

Neither EBS nor Customer shall be in default under this Agreement with respect to any delay in its performance caused
by any of the following conditions (each a "Force Majeure Event"):  (a) act of God; (b) fire; (c) flood; (d) material
shortage or unavailability not resulting from the responsible party's failure to timely place orders or take other
necessary actions therefor; (e) (lack of or delay in third-party transportation service or access to the System; (f)
delays caused by governmental officials and entities in connection with the compliance by such party with applicable
government codes, ordinances, laws, rules, regulations or restrictions (collectively, "Regulations") (but not to the
extent the delay caused by such Regulations could be avoided by rerouting the Cable if such a reroute was
commercially reasonable); (g) war or civil disorder; or (h) any other cause beyond the reasonable control of such
party; provided, however, that with respect to the payment of money this Article XVIII shall excuse failure to pay
       --------  --------
when due for no more than ten (10) days, and interest shall accrue whether or not such failure to pay is so excused.
The party claiming relief under this Article XVIII shall promptly notify the other in writing of the existence of the
Force Majeure Event relied on, the expected duration of the Force Majeure Event, and the cessation or termination of
the Force Majeure Event.  The party claiming relief under this Article XVIII shall be entitled to invoke Force
Majeure only for so long as it exercises commercially reasonable efforts to minimize the time for any such delay.

ARTICLE XIX.                                                   ARBITRATION
                                                               -----------

19.1.    Any dispute or disagreement arising between EBS and Customer in connection with this Agreement that is not
settled to their mutual satisfaction within the applicable notice or cure periods provided in this Agreement, shall
be settled by arbitration in Dallas, Texas in accordance with the Commercial Arbitration Rules of the American
Arbitration Association in effect on the date that such notice is given.  Discovery shall be permitted in accordance
with the Federal Rules of Civil Procedure.  If EBS and Customer cannot agree on a single arbitrator within fifteen
(15) days after the applicable notice or cure period has expired, EBS and Customer shall each select an arbitrator
within such fifteen (15) day period and the two (2) arbitrators shall select a third arbitrator within ten (10)
days.  If the Parties fail to appoint arbitrators or the arbitrators cannot agree on a third arbitrator, then either
Party may request that the American Arbitration Association select and appoint a neutral arbitrator who shall act as
the sole arbitrator.  The decision of the arbitrator or arbitrators shall be final and binding upon EBS and Customer
and shall include written findings of law and fact, and judgment may be obtained thereon by either EBS or Customer in
a court of competent jurisdiction.  EBS and Customer shall each bear the cost of preparing and presenting its own
case.  The cost of the arbitration, including the fees and expenses of the arbitrator or arbitrators, shall be shared
equally by EBS and Customer unless the award otherwise provides.  The arbitrator or arbitrators shall be instructed
to establish procedures such that a decision can be rendered within sixty (60) days of the appointment of the
arbitrator or arbitrators.  In no event shall the arbitrator or arbitrators have the power to award any damages for
lost or prospective profits, or any other special, punitive, exemplary, consequential, incidental or indirect losses
or damages as a result of the performance or nonperformance of its obligations under this Agreement, or its acts or
omissions related to this Agreement, whether or not arising from sole, joint or concurrent negligence, strict
liability, or otherwise, regardless of whether such damages may be available under applicable law.  EBS and Customer
hereby waive their rights, if any, to recover any such damages, whether in arbitration or litigation.

19.2.    The obligation to arbitrate shall not be binding upon any Party with respect to requests for preliminary
injunctions, temporary restraining orders, specific performance or other procedures in a court of competent
jurisdiction to obtain interim relief when deemed necessary by such court to preserve the status quo or prevent
irreparable injury pending resolution by arbitration of the actual dispute or to enforce a judgment awarded at
arbitration.

                                                                 ------

The failure of either EBS or Customer to enforce any of the provisions of this Agreement, or the waiver thereof in
any instance, shall not be construed as a general waiver or relinquishment on its part of any such provision, but the
same shall nevertheless be and remain in full force and effect.

attorneys fees and court costs at trial and on appeal) incurred in discharging and releasing such lien; provided
