         C.       QWEST desires to grant NETWORK a right to use certain fibers
and other rights in regeneration facilities on and along the New York - Boston
Segment;

         Accordingly, in consideration of the mutual promises set forth below,
and other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties hereby agree as follows:


                                    ARTICLE 1

                  GRANT OF IRU IN THE NEW YORK - BOSTON SYSTEM

         1.1      Effective as of the date when both the Delivery Date as
defined in Section 4.3 has occurred and the IRU Fee provided for in Section 2.1
has been paid, QWEST hereby grants to NETWORK and NETWORK hereby purchases from
QWEST an exclusive indefeasible right of use ("IRU"), for the purposes described
herein, in four (4) dark fibers, to be specifically identified, in the New York

                                    ARTICLE 3

                  CONSTRUCTION OF THE NEW YORK - BOSTON SEGMENT




   2

         3.1      QWEST represents and NETWORK acknowledges that the New York -
Boston Segment is being constructed by the THIRD PARTY. QWEST represents that
the Segment will be constructed in accordance with the construction
specifications set forth in Exhibit B, industry standards and practices,
applicable building construction and safety codes for such construction and
installation, as well as any and all other applicable governmental laws, codes,
ordinances, statutes and regulations, and to perform in accordance with the
manufacturers' specifications set forth in Exhibit C (Fiber Specifications) and
to operate in accordance with Exhibit D (Fiber Cable Splicing, Testing and
Acceptance Procedures). All NETWORK Fibers will be Lucent True Wave. 

         3.2      QWEST represents and warrants that QWEST or the THIRD PARTY 
have the obligation to obtain or have obtained all Required Rights (as defined
in Section 6.1) and other rights, licenses, permits and authorizations as
required to construct the New York - Boston Segment. Upon NETWORK's written
request, QWEST shall make available for inspection by NETWORK, at QWEST's
offices, copies of all information, documents, agreements, reports, permits,
drawings and specifications obtained by QWEST from the THIRD PARTY and
pertaining to this Article 3 that in QWEST's reasonable determination are
material to the grant of the IRU to NETWORK including, without limitation, the
Required Rights to the extent that the terms of each such document or the legal
restrictions applicable to such information or document permits disclosure and
further as may be redacted to protect disclosure of confidential business and
proprietary terms. QWEST represents that any redacted portions of the Required
Rights documents shall not materially affect the rights of NETWORK granted
hereunder.

                                    ARTICLE 4

                    ACCEPTANCE AND TESTING OF NETWORK FIBERS


         4.1      QWEST represents and warrants that the THIRD PARTY will test
all NETWORK Fibers in accordance with the procedures specified in Exhibit D
("Fiber Cable Splicing, Testing and Acceptance Procedures") to verify that the
NETWORK Fibers are installed and operational in accordance with the
specifications described in Exhibit C. As QWEST is provided notice by the THIRD
PARTY, QWEST shall provide NETWORK notice of the date and time of Fiber
Acceptance Testing such that NETWORK shall have the opportunity to have a person
or persons present to observe the Fiber Acceptance Testing. QWEST will provide
NETWORK with copies of all test results obtained from the THIRD PARTY pertaining
to the NETWORK Fibers prior to acceptance.

         4.2      In the event the Fiber Acceptance Testing results show that
the NETWORK Fibers are not installed or operating within the parameters of the
applicable specifications, QWEST shall take or cause the THIRD PARTY to take
such action as shall be reasonably necessary with respect to such portion of the
NETWORK Fibers as are not installed or do not operate within the parameters of
the applicable specifications to bring the installation and operating standards
of such portion of the NETWORK Fibers within such parameters. After taking such
actions, QWEST shall cause the THIRD PARTY to provide a copy of the new test
results and QWEST shall provide a copy to NETWORK within fourteen (14) days of
the conclusion of the Fiber Acceptance Testing. The cycle described above of
testing, taking corrective action and re-testing shall take place as many time
as necessary to ensure that the NETWORK Fibers operate within the parameters of
the applicable specifications.

         4.3      If the Fiber Acceptance Testing results are within the
parameters of the specifications in Exhibit D, NETWORK shall, within seven (7)
days of receipt of the test results, provide QWEST with a written notice
accepting the NETWORK Fibers. If NETWORK fails to accept its Fibers within seven
(7) days of receipt of the Fiber Acceptance Testing results, then NETWORK shall
be deemed to have accepted its Fibers unless it notifies QWEST within seven (7)
days of receipt of the Fiber Acceptance Testing results that such results are
unacceptable. The date of this notice or the date of deemed acceptance of the
NETWORK Fibers shall be the "Acceptance Date". Notwithstanding Acceptance as
provided herein, the parties agree that subject to extensions for delay
described in Article 20, Force Majeure, the date upon which QWEST will grant the
IRU to NETWORK after Acceptance Testing (the "Delivery Date") will be a date
which is mutually agreeable to the parties but in no event later than December
31, 1998. QWEST will use reasonable efforts to make available Dark Fibers for
lease to NETWORK prior to the Delivery Date subject to completion of the Segment
by the THIRD PARTY.

                                  ARTICLE 5

                                DOCUMENTATION


         5.1      Not later than ninety (90) days after the Acceptance Date,
QWEST shall provide NETWORK with the following documentation which shall be
complete, true and correct:

                  (a)      As-built drawings for the Segment in accordance with
the requirements described in Exhibit B.

                  (b)      Technical specifications of the optical fiber cable
and associated splices and other equipment placed in the Segment including test
results.


                                    ARTICLE 6

                                      TERM

         6.1      The term of this Agreement shall begin on the Effective Date
and shall end at the earlier of the end of the economically useful life of the
NETWORK Fibers (the "Term") or subject to the provisions of Article 10, such
time as right of way agreements, including without limitation, rights, licenses,
authorizations, rights of way, and other agreements necessary for the use of
poles, conduit, cable, wire or other physical plant facilities, as well as any
other such rights, licenses, authorizations (including any necessary state,
tribal or federal authorizations such as environmental permits), rights of way
and other agreements necessary for the installation and use of the NETWORK
Fibers (all of which are referred to as the "Required Rights") are no longer
available to QWEST.

         6.2      In the event that NETWORK, at any time, reasonably determines
that the NETWORK Fibers have reached the end of their economically useful life
and desires not to retain the IRU, NETWORK shall have the right to abandon the
IRU by written notice to QWEST. If, at any time during or after the last year of
the Term, NETWORK fails to use any of the NETWORK Fibers for any period of
thirty (30) consecutive days (except to the extent that such non-use is as a
result of any of the events described in Article 20 or as a result of
maintenance, restoration, relocation, or reconfiguration or as a result of the
failure of QWEST to observe and perform the terms of this Agreement), QWEST
shall give notice to NETWORK of proposed abandonment. In the event NETWORK fails
to notify QWEST within sixty (60) days of its intent to continue use of the
Fibers, NETWORK shall be deemed to have determined that the NETWORK Fibers have
reached the end of their economic life and, accordingly, has abandoned the
NETWORK Fibers. Upon any such notice of abandonment or acknowledgement of
abandonment, the Term of this Agreement shall expire and all rights to the New
York - Boston Segment and the use of such Segment shall revert to QWEST without
reimbursement of any fees or other payments previously made with respect
thereto, and from and after such time NETWORK shall have no further rights or
obligations hereunder with respect to such Segment (subject to the provisions of
Articles 12 and 17).

         6.3      It is understood and agreed that the THIRD PARTY must and does
maintain legal title to the entire New York - Boston Segment subject to the IRU
hereunder. Notwithstanding the foregoing, it is understood and agreed as between
the parties that the grant of the IRU hereunder shall be treated for accounting
and federal and all applicable state and local tax purposes as the sale and
purchase of the NETWORK Fibers, and that on or after the Acceptance Date with
respect to the Segment, NETWORK shall be treated as the owner of the NETWORK
Fibers comprising the Segment for such purposes. The parties agree to file their
respective income tax returns, property tax returns, and other returns and
reports for their respective Impositions on such basis and, except as otherwise
required by law, not to take any positions inconsistent therewith. QWEST
represents and warrants that it will not convey any interest, including any
security interest, in the New York to Boston Segment, to any other entity in any
manner which is not fully consistent with, and subordinate to, NETWORK's rights
under this Agreement.


                                    ARTICLE 7

                     NETWORK ACCESS; REGENERATION FACILITIES

         7.1      QWEST shall provide NETWORK with access to the NETWORK Fibers
by a cable stub taken from the system by the THIRD PARTY and delivered to QWEST
at a QWEST designated location or, as mutually agreed to by the parties, in
selected THIRD PARTY POPs at the fiber distribution panel. All connections shall
be performed by QWEST, at NETWORK's sole cost and expense, in accordance with
QWEST's applicable specifications

Exchange Commission. Asterisks denote omissions.



and operating procedures. NETWORK shall pay QWEST's costs for each such
connection within thirty (30) days of the date of NETWORK's receipt of QWEST's
invoice therefor. NETWORK shall have no limitations on the types of electronics
or technologies employed to utilize the NETWORK Fibers, subject to mutually
agreeable safety procedures and so long as such electronics or technologies do
not interfere with the use of or present a risk of damage to any portion of
QWEST's network. QWEST may route in the NETWORK Fibers through QWEST's separate
terminal endlink, POP or Regeneration Facilities at its sole discretion so long
as such routing does not have a material adverse effect on the security, the
safety or NETWORK's use of the NETWORK Fibers hereunder and QWEST is responsible
for all costs and expenses associated therewith.

         7.2      Exhibit E sets forth the sites along the New York to Boston
Segment at which regeneration facilities currently are located or are to be
installed in accordance with the Specifications set forth on Exhibit F which
NETWORK desires to share with QWEST (collectively, the "Regeneration
Facilities"). Subject to (a) the availability of adequate and sufficient
Required Rights, space, power, and right-of-way access, and (b) the receipt of
all requisite permits, approvals and authorizations, available to NETWORK, QWEST
will make space available for up to one rack in certain regeneration facilities
and up to two racks in certain POPs available to NETWORK on a shared basis for a
cost per facility of $[**] per rack. All shared Regeneration Facilities shall
be subject to the provisions of this Agreement, and in particular Section 8.2
with respect to sharing of operating costs thereof.


                                    ARTICLE 8

                                   OPERATIONS

         8.1      Each party shall have full and complete control and
responsibility for determining any network and service configurations or
designs, routing configurations, regrooming, rearrangement or consolidation of
channels or circuits and all related functions with regard to the use of that
party's Dark Fiber.

         8.2      NETWORK shall reimburse QWEST for NETWORK's proportionate
share of all operating costs incurred by QWEST in connection with the
Regeneration Facilities provided pursuant to Section 7.2, including its
proportionate share of any monthly lease costs for any such facilities and/or
underlying property that QWEST leases (including, to the extent included in such
lease costs, base rent, maintenance, insurance, security and taxes), maintenance
of such facilities, and all power and utility fees and charges. NETWORK's
proportionate share of such operating costs, including a proportionate share of
common area costs, shall be the ratio that the floor space provided to NETWORK
in any such facility (including a proportionate share of the common area) bears
to (1) in the case of lease costs, the total space in such facility, and (2) in
the case of all other costs (including common area costs), the total utilized
space in such facility. QWEST shall submit invoices to NETWORK on an annual
basis for NETWORK's prorata share of such operating costs during the preceding
twelve months. QWEST will operate the Regeneration Facilities in a commercially
reasonable manner. NETWORK's reimbursement obligations for insurance and taxes
pursuant to this Section 8.2 shall in no event be duplicative of NETWORK's
payment obligations for insurance or taxes, respectively, as provided in Article
15 hereof, and in no event shall QWEST be relieved of its payment obligations
for insurance costs or taxes, respectively.

         8.3      NETWORK acknowledges and agrees that, except as expressly
provided in Section 7.2, QWEST is not supplying nor is QWEST obligated to supply
to NETWORK any optronics or electronics or optical or electrical equipment or
other facilities, including, without limitation, generators, batteries, air
conditioners, fire protection and monitoring and testing equipment, all of which
are the sole responsibility of NETWORK, nor is QWEST responsible for performing
any work other than as specified in this Agreement.


                                    ARTICLE 9

             MAINTENANCE AND REPAIR OF THE NEW YORK - BOSTON SEGMENT

         9.1      From and after the Acceptance Date the maintenance of the New
York - Boston Segment shall be provided in accordance with the maintenance
requirements and procedures set forth in Exhibit G hereto.

                                   ARTICLE 10

                      PERMITS, REQUIRED RIGHTS; RELOCATIONS

         10.1      QWEST represents and warrants that on or before the Delivery
Date with respect to the Segment to be delivered hereunder, the THIRD PARTY is
responsible to obtain any Required Rights and, thereafter, to use commercially
reasonable efforts to cause the Required Rights to remain in effect for a
minimum term of twenty years (the "Minimum Period"). QWEST agrees to exercise
all commercially reasonable efforts to enforce its rights to require Specific
Performance of the THIRD PARTY's obligations and other remedies available to
QWEST under its Agreement with the THIRD PARTY to keep the Required Rights in
force for the Minimum Period. QWEST acknowledges that its failure to exercise
such efforts will cause NETWORK irreparable harm, and that accordingly, NETWORK
shall have the right to obtain specific performance of QWEST's obligations set
forth in the preceding sentence.

         10.2      Upon the expiration or termination of any Required Right that
is necessary in order to grant, continue or maintain the IRU granted hereunder
in accordance with the terms and conditions hereof, and so long as QWEST shall
have fully observed and performed its obligations under this Article 10 with
respect thereto, the Term of the IRU hereunder with respect to the Segment, or
any portion of the Segment affected by such expiration or termination of a
Required Right, shall automatically expire upon such expiration or termination
of the Required Right.

         10.3      If, after the Acceptance Date with respect to the Segment,
(i) the THIRD PARTY or QWEST reasonable determines, or (ii) the THIRD PARTY or
QWEST is required by a third party with legal authority to so require
(including, without limitation, the grantor of a Required Right), or (iii)
NETWORK agrees to relocate any portion of the Segment, including any of the
facilities used or required in providing the IRU in such Segment hereunder,
QWEST or the THIRD PARTY, as applicable, shall proceed with such relocation, and
shall have the right, in good faith, to reasonably determine the extent of, the
timing of, and methods to be used for such relocation; PROVIDED THAT (a) any
such relocation shall be constructed and tested in accordance with the
specifications and drawings set forth in Exhibits B and C, and incorporate fiber
meeting the specifications set forth in Exhibit D and (b) if the relocation is
pursuant to (i) above, or subject to Article 20, to (ii) above, it shall not
adversely affect the operations, performance, connection points with NETWORK's
network or endpoints of the Segment.

         10.4      Unless QWEST is reimbursed by a third party (which does not
have an interest in the fibers in the cable) NETWORK shall reimburse QWEST for
its proportionate share of all costs of such relocation, including without
limitation conduit relocation, fiber acquisition, splicing and testing, of the
portion of the Segment based on the proportion of the NETWORK Fibers to the
total fibers in the cable.


                                   ARTICLE 11

                        USE OF NEW YORK - BOSTON SEGMENT

         11.1     The requirements, restrictions, and/or limitations upon
NETWORK's right to use the NETWORK Fibers as provided and permitted under this
Agreement imposed under, and associated safety, operational and other rules and
regulations imposed in connection with, the Required Rights are referred to
collectively as the "Required Rights Requirements." NETWORK acknowledges and
agrees that it is taking its IRU on an "as is, where is" basis and that it is
receiving the interests in such IRU Fibers as set forth in this Agreement only
to the extent such interests are held by the conveying party.

         11.2     Each of the parties represents, warrants and covenants that it
will use its fibers in compliance with and subject to the Required Rights
Requirements (to the extent provided by the THIRD PARTY and known to QWEST and
NETWORK) and all applicable government codes, ordinances, laws, rules and
regulations.

         11.3     The IRU granted hereunder shall include the right at NETWORK's
cost to install additional equipment, or replaces existing equipment, in the
facility space provided to NETWORK pursuant to Article 7, subject to the
provisions of Article 7 and the Required Rights Requirements.

         11.4     QWEST agrees and acknowledges that it has no right to use the
NETWORK Fibers during the Term hereof, and that, from and after the effective
date of the


                                       -5-


   6


Agreement, QWEST shall keep the NETWORK Fibers and NETWORK's IRU granted
hereunder free from (a) any liens of any third party attributable to QWEST, and
(b) any rights or claims of any third party attributable to QWEST, as and to the
extent required pursuant to Article 10 hereof. As provided in the previous
sentence, QWEST shall obtain from any entity in favor of which QWEST in its
discretion shall have granted after the date hereof a security interest or lien
on all or part of the Segment a written nondisturbance agreement substantially
to the effect that such lienholder acknowledges NETWORK's rights and interests
in and to the NETWORK Fibers and the IRU hereunder and agrees that the same
shall not be diminished, disturbed, impaired or interfered with in any adverse
respect by such lienholder. QWEST represents that this same or similar provision
is in all other agreements under which QWEST has granted IRUs in the New York to
Boston Segment.

         11.5     Subject to the provisions of Article 22 and this Article 11,
NETWORK may use the NETWORK Fibers and the IRU for any lawful telecommunications
purpose. NETWORK agrees and acknowledges that it has no right to use any of the
fibers, other than the NETWORK Fibers, included in the cable or otherwise
incorporated in the New York - Boston Segment, and that NETWORK shall keep any
and all of the New York - Boston Segment, other than the IRU granted to NETWORK
in the NETWORK Fibers free from any liens, rights or claims of any third party
attributable to NETWORK.

         11.6     NETWORK and QWEST shall promptly notify each other of any
matters pertaining to, or the occurrence (or impending occurrence) of any event
which would be reasonably likely to give rise to any damage or impending damage
to or loss of the New York - Boston Segment that are known to such party.

         11.7     NETWORK shall not use the NETWORK Fibers in a way which
physically interferes in any way with or adversely affects the use of the fibers
or cable of any other person using the New York - Boston Segment. QWEST shall
not use any other fibers in the New York - Boston Segment in a way which
physically interferes with or adversely affects the use of the NETWORK Fibers.
QWEST represents that this same or similar provision is in all other agreements
under which QWEST has granted IRUs in the New York to Boston Segment. 

         11.8     NETWORK and QWEST each agree to cooperate with and support the
other in complying with any requirements applicable to their respective rights
and obligations hereunder by any governmental or regulatory agency or authority.

                                 INDEMNIFICATION

         12.1     Subject to the provisions of Articles 13 and 18, QWEST hereby
agrees to indemnify, defend, protect and hold harmless NETWORK and its
employees, officers and directors, from and against, and assumes liability for:

                  (a)      Any injury, loss or damage to any person (including
NETWORK), tangible or intangible property or facilities of any person or entity
(including reasonable attorneys' fees and costs) to the extent arising out of or
resulting from the acts or omissions, negligent or otherwise, of QWEST, its
officers, employees, servants, affiliates, agents, contractors, or licensees
arising out of or in connection with a default (other than a default caused by a
failure of NETWORK to perform or comply with its obligations hereunder) by QWEST
in the performance of its obligations or breach of its representations under
this Agreement; and

                  (b)      Any claims, liabilities or damages, including
reasonable attorneys' fees and costs, arising out of any violation by QWEST of
any regulation, rule, statue or court order of any local, state or federal
governmental agency, court or body in connection with the performance of its
obligations under this Agreement.

         12.2     Subject to the provisions of Articles 13 and 18, NETWORK
hereby agrees to indemnify, defend, protect and hold harmless QWEST, and its
employees, officers and directors, from and against, and assumes liability for:

                  (a)      Any injury, loss or damage to any person (including
QWEST), tangible or intangible property or facilities of any person or entity
(including reasonable attorneys' fees and costs) to the extent arising out of or
resulting from the acts or omissions, negligent or otherwise, of NETWORK, its
officers, employees, servants, affiliates, agents, contractors, licensees,
invitees or vendors arising out of or in connection with a default (other than a
default caused by a failure of QWEST

to perform or comply with its obligations hereunder) by NETWORK in the
performance of its obligations or breach of its representations under this
Agreement; and

                  (b)      Any claims, liabilities or damages, including
reasonable attorneys' fees and costs, arising out of any violation by NETWORK of
any regulation, rule, statue or court order of any local, state or federal
governmental agency, court or body in connection with its use of the IRU and/or
the NETWORK Fibers and Associated Property hereunder. 

         12.3     The parties hereby expressly recognize and agree that each
party's said obligation to indemnify, defend, protect and save the other
harmless is not a material obligation to the continuing performance of the
parties' other obligations, if any, hereunder. In the event that a party shall
fail for any reason to so indemnify, defend, protect and save the other
harmless, the injured party hereby expressly recognizes that its sole remedy in
such event shall be to seek a remedy under Article 21 against the other party
for its damages as a result of the other party's failure to indemnify, defend,
protect and save harmless. The obligations of the parties under this Article 12
shall survive the expiration or termination of this Agreement.

         12.4     Nothing contained herein shall operate as a limitation on the
right of either party hereto 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
operation or use of the NETWORK Fibers or the QWEST network, except as may be
limited by Required Rights Requirements; PROVIDED, HOWEVER, that each party
hereto shall assign such rights or claims, execute such documents and do
whatever else may be reasonably necessary to enable the other party to pursue
any such action against such third party.

                             LIMITATION OF LIABILITY

         13.1     Notwithstanding any provision of this Agreement to the
contrary, neither party shall be liable to the other party for any special,
incidental, indirect, punitive or consequential damages, whether foreseeable or
not, arising out of, or in connection with such party's failure to perform its
respective obligations or breach of its respective representations hereunder,
including, but not limited to, damage or loss of property or equipment, loss of
profits or revenue, cost of capital, (whether arising out of transmission
interruptions or problems, any interruption or degradation of service or
otherwise), or claims of customers, in each case whether occasioned by any
construction, reconstruction, relocation, repair or maintenance performed by, or

liability, all claims with respect to which such special, incidental, indirect,

                                    INSURANCE

         14.1     Following the Delivery Date with respect to the Segment, and
throughout the Term of the IRU with respect to the Segment, each party shall
procure and maintain in force, at its own expense:

                  (a)      not less than $[**] combined single limit
liability insurance, on an occurrence basis, for personal injury and property
damage, including, without limitation, injury or damage arising from the
operation of vehicles or equipment and liability for completed operations;

                  (b)      workers' compensation insurance in amounts required
by applicable law and employers' liability insurance with a limit of at least
$[**] per occurrence; and

                  (c)      automobile liability insurance covering death or
injury to any person or persons, or damage to property arising from the
operation of vehicles or equipment, with limits of not less than $[**] per
occurrence; and

         14.2     Both parties expressly acknowledge that a party shall be
deemed to be in compliance with the provisions of this Article 14 if it
maintains an approved self-insurance program providing for a retention of up to
$[**]. If either party



                                       -7-

provides any of the foregoing coverages on a claims-made basis, such policy or
policies shall be for at least a three-year extended reporting or discovery
period. Unless otherwise agreed, NETWORK's and QWEST's insurance policies shall
be obtained and maintained with companies rated "A" or better by Best's Key
Rating Guide and each party shall provide the other with an insurance
certificate confirming compliance with this requirement for each policy
providing such required coverage.

         14.3     In the event either party fails to obtain the required
insurance and a claim is made or suffered, such party shall indemnify and hold
harmless the other party from any and all claims for which the required
insurance would have provided coverage. Further, in the event of any such
failure which continues after seven (7) days' written notice thereof by the
other party, such other party may, but shall not be obligated to, obtain such
insurance and will have the right to be reimbursed for the cost of such
insurance by the party failing to obtain such insurance.

         14.4     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 good-faith efforts to pursue such claim
with its carrier.

         14.5     Both parties shall obtain from their insurance companies
providing the coverages required by this Agreement the permission of such
insurers to allow that party to waive all rights of subrogation and each party
does hereby waive all rights of said insurance companies to subrogation against
the other, its parent corporation, affiliates, subsidiaries, assignees,
officers, directors, and employees or any other party entitled to indemnify
under this Agreement.


                                   ARTICLE 15

                 TAXES, FEES AND OTHER GOVERNMENTAL IMPOSITIONS

         15.1     The parties acknowledge and agree that it is their mutual
objective and intent to (a) minimize, to the extent feasible, the aggregate
Impositions payable with respect to the New York - Boston Segment and (b) share
such Impositions according to their respective interests in the New York -
Boston Segment, and that they will cooperate with each other and coordinate
their mutual efforts to achieve such objectives in accordance with the
provisions of this Article 15. It is understood and agreed as between the
parties that the grant of the IRU in the NETWORK Fibers shall be treated for
accounting and federal and all applicable state and local tax purposes as the
sale and purchase of the NETWORK Fibers and that on or after the Acceptance
Date, NETWORK shall be treated as the owner of the NETWORK Fibers for such
purposes. The parties agree to file their respective income tax returns,
property tax returns, and other returns and reports for their respective
Impositions on such basis and except as otherwise required by law, not to take
any positions inconsistent therewith.

                                 CONFIDENTIALITY

         17.1     (a)      QWEST and NETWORK hereby agree that if either party
provides (or, prior to the execution hereof, has provided) confidential or
proprietary information to the other party ("Proprietary Information"), such
Proprietary Information shall be held in confidence, and the receiving party
shall afford such Proprietary Information the same care and protection as it
affords generally to its own confidential and proprietary information (which in
any case shall be not less than reasonable care) in order to avoid disclosure to
or unauthorized use by any third party.

                  (b)      As used herein, Proprietary Information shall mean
any and all technical or business information furnished, in whatever form or
medium, or disclosed by QWEST to NETWORK including, but not limited to, product
or service specifications, prototypes, computer programs, models, drawings,
marketing plans, financial data, and personnel statistics. In addition, the
parties acknowledge and agree that this Agreement, including all of the terms,
conditions and provisions hereof, all drafts hereof, and all information
disclosed by either party to the other in connection with or pursuant to this
Agreement constitutes Proprietary Information.

                  (c)      All Proprietary Information, unless otherwise
specified in writing, shall remain the property of the disclosing party, shall
be used by the receiving party only for the intended purpose of performing its
obligations under this Agreement, and such written Proprietary Information,
including all copies thereof, shall be returned to the disclosing party or
destroyed after the receiving party's need for it has expired or upon the
request of the disclosing party. Proprietary Information shall not be reproduced
except to the extent necessary to accomplish the purpose and intent of this
Agreement, or as otherwise may be permitted in writing by the disclosing party.

         17.2     The foregoing provisions of Section 17.1 shall not apply to

disclosure is reasonably necessary in connection with the settlement of any
dispute or enforcement of either party's rights under this Agreement in
accordance with the provisions of this Agreement, in which case appropriate
protective measures shall be taken to preserve the confidentiality of such
Proprietary Information as fully as possible within the confines of such
settlement or enforcement process. If any Proprietary Information is required to
be disclosed pursuant to the foregoing clause (b), the party required to make
such disclosure shall promptly inform the other party of the requirements of
such disclosure and shall cooperate with the other party in seeking a protective
order or similar relief.

promotions, or other publicity materials that use the other party's logo,
trademarks, or service marks without the prior written approval of the other
party.

         17.4     Each party shall have the right to review and approve any

statements without the prior written approval of the other party.

party to use any of the other party's brands, marks or logos without prior
written approval of the other party.

         17.6     Nothing herein shall be construed as granting any right or
license under any copyrights, inventions, or patents now or hereafter owned or
controlled by QWEST.

         17.7     Notwithstanding Sections 17.1 and 17.2 of this Article, either
party may disclose Proprietary Information to its employees, agents, and legal,
financial, and accounting advisors and providers (including its lenders and
other financiers) to the extent necessary or appropriate in connection with the
negotiation and/or performance of this Agreement or its obtaining of financing,
PROVIDED THAT each such party is notified of the confidential and proprietary
nature of such Proprietary Information and is subject to or agrees to be bound
by similar restrictions on its use and disclosure.

termination of this Agreement for a period of three years thereafter.


                                   ARTICLE 18

                                     DEFAULT

         18.1     With respect to all payments required to be made by NETWORK
hereunder, including, without limitation, payment of the IRU Fee and all other
amounts payable by NETWORK hereunder, if NETWORK fails to make a payment by the
date due and payable hereunder, from and after such date, (a) such unpaid amount
shall bear accrued interest compounded monthly until paid at an annual rate
equal to one hundred fifty percent ([**]%) of the prime rate of interest
published by the Wall Street Journal the date any such payment is due or, if
lower, the highest percentage allowed by law and (b) if such payment is due with
respect to the Segment on or prior to the Acceptance Date of the Segment, the
Estimated Delivery Date for the Segment shall be extended by a number of days
equal to the number of days that elapse from the date such payment is due until
paid. In the event any amount or amounts due and payable hereunder remain unpaid
for a period of thirty (30) days after written notice from QWEST to NETWORK,
then QWEST may, in its sole and absolute discretion and in addition to its other
rights and remedies hereunder, terminate any and all of its obligations
hereunder with respect to the Segment, and to apply any and all amounts
previously paid by NETWORK hereunder with respect to the Segment toward the
payment of any other amounts then or thereafter payable by NETWORK hereunder.

                  With respect to all of its other obligations hereunder, if
NETWORK fails to perform a nonpayment obligation and such failure shall continue
for a period of thirty (30) days after QWEST shall have given NETWORK written
notice of such failure, NETWORK shall be in default hereunder unless NETWORK
shall have cured such failure or such failure is otherwise waived in writing by
QWEST within such thirty (30) days; PROVIDED, HOWEVER, that where such failure
cannot reasonably be cured within such 30- day period, if NETWORK shall proceed
promptly to cure the same and prosecute such cure with due diligence, the time
for curing such failure shall be extended for such period of time as may be
necessary to complete such cure; and PROVIDED FURTHER that if NETWORK certifies
in good faith to QWEST in writing that a nonpayment failure has been cured, such
failure shall be deemed to be cured unless QWEST otherwise notifies NETWORK in
writing within fifteen (15) days of receipt of such notice from NETWORK.

                  NETWORK shall be in default hereunder (a) automatically upon
the making by NETWORK or Parent of a general assignment for the benefit of its
creditors, the filing by NETWORK or Parent of a voluntary petition in bankruptcy
or the filing by NETWORK or Parent of any petition or answer seeking, consenting
to, or acquiescing in reorganization, arrangement, adjustment, composition,
liquidation, dissolution, or




                                      -10-


   11


similar relief; or (b) one hundred twenty (120) days after the filing of an
involuntary petition in bankruptcy or other insolvency protection against
NETWORK which is not dismissed within such one hundred twenty (120) days.

                  Except as otherwise provided in this Section 18.1, upon any
default by NETWORK, after written notice thereof from QWEST, QWEST may (a) take
such action as it determines, in its sole discretion, to be necessary to correct
the default and, subject to Section 13.1, recover from NETWORK its reasonable
costs incurred in correcting such default, and (b) pursue any legal remedies it
may have under applicable law or principles of equity relating to such default,
including specific performance.

         18.2     With respect to QWEST's obligations hereunder, in the event
that QWEST shall fail to perform an obligation and such failure shall continue
for a period of thirty (30) days after NETWORK shall have given QWEST written
notice of such failure, QWEST shall be in default hereunder unless QWEST shall
have cured such failure or such failure is otherwise waived in writing by
NETWORK within such thirty (30) days; PROVIDED HOWEVER, that where such failure
cannot reasonably be cured within such 30-day period, or if QWEST's failure is
a failure of the THIRD PARTY to complete the construction, installation and
satisfactory Fiber Acceptance Testing by the Estimated Delivery Date for the
Segment pursuant to Section 4.3, or QWEST's failure to deliver an IRU in the
fibers pursuant to RECITAL A, if QWEST shall proceed promptly to cure the same
and prosecute such cure with due diligence, or with respect to the Estimated
Delivery Date, shall proceed to diligently complete or to cause the THIRD PARTY
to complete the construction, installation and testing, the time for curing such
failure, including a failure to meet an Estimated Delivery Date, shall be
extended for such period of time as may be necessary to complete such cure or
such construction, installation and testing; and PROVIDED FURTHER, that if QWEST
certifies in good faith to NETWORK in writing that failure has been cured, such
failure shall be deemed to be cured unless NETWORK otherwise notifies QWEST in
writing within fifteen (15) days of receipt of such notice from QWEST.
Notwithstanding the foregoing provisions of this paragraph, in the event a force
majeure event or occurrence described in Article 20 or any other event causes an
extension of the Estimated Delivery Date and such event or occurrence has not
been terminated, avoided or resolved by the date that is six (6) months
following the Estimated Delivery Date, NETWORK may elect, in its sole
discretion, by written notice to QWEST, to terminate this Agreement and recover
from QWEST the amount of the IRU Fee previously paid by NETWORK hereunder with
respect to the Segment. Upon any such election and payment, neither party shall
have any further rights or obligations.

                  QWEST shall be in default hereunder (a) automatically upon the
making by QWEST of a general assignment for the benefit of its creditors, the
filing by QWEST of a voluntary petition in bankruptcy or the filing by QWEST of
any petition or answer seeking, consenting to, or acquiescing in reorganization,
arrangement, adjustment, composition, liquidation, dissolution, or similar
relief, or (b) one hundred twenty (120) days after the involuntary filing of a
petition in bankruptcy or other insolvency protection against QWEST which is not
dismissed within such 120-day period.

                  Except as otherwise provided in this Section 18.02, upon any
default by QWEST, after notice thereof from NETWORK, NETWORK may (a) take such
action as it determines, in its sole discretion, to be necessary to correct the
default, and, subject to Section 13.01, recover from QWEST its reasonable costs
in correcting such default, and (b) pursue any legal remedies it may have under
applicable law or principles of equity relating to such default including
specific performance.


                                   ARTICLE 19

                                   TERMINATION

         19.1     This Agreement automatically shall terminate with respect to a
Segment upon the expiration or termination of the Term of the IRU respecting the
Segment pursuant to Article 6 or Section 17.02 hereof.

         19.2     Upon the expiration or termination of this Agreement, the IRU
shall immediately terminate and all rights of NETWORK to use the Segment, the
NETWORK Fibers, the associated property or any part thereof relating to the
Segment, shall cease and QWEST shall owe NETWORK no additional duties or
consideration with respect to the Segment. Promptly thereupon, NETWORK shall
remove all of NETWORK's electronics, equipment, and other NETWORK property from
such Segment and any related




                                      -11-


   12


QWEST facilities at its sole cost, under QWEST's supervision (which supervision
shall be without cost to NETWORK).

         19.3     Notwithstanding the foregoing, no termination or expiration of
this Agreement shall affect the rights or obligations of any party hereto (a)
with respect to any then existing defaults or the obligation to make any payment
hereunder for services rendered prior to the date of termination or expiration,
(b) with respect to any accrued liability for taxes pursuant to Article 15, or
(c) pursuant to Article 12, Article 13, or Article 17 herein, which shall
survive the expiration or termination hereof.


                                   ARTICLE 20

                                  FORCE MAJEURE

         20.1     Neither party shall be in default under this Agreement if and
to the extent that any failure or delay in such party's performance of one or
more of its obligations hereunder is caused by any of the following conditions,
and such party's performance of such obligation or obligations shall be excused
and extended for and during the period of any such delay: act of God; fire;
flood; fiber, Cable, or other material failures, shortages or unavailability or
other delay in deliver not resulting from the responsible party's failure to
timely place orders therefor (it being expressly acknowledged that the Cable
that is being acquired for and installed in the New York - Boston Segment and
that will include the NETWORK Fibers must include higher fiber counts than that
necessary solely for the NETWORK Fibers in order to permit completion of the
entire New York - Boston Segment); lack of or delay in transportation;
government codes, ordinances, laws, rules, regulations or restrictions; war or
civil disorder; strikes or other labor disputes; failure of a third party to
grant or recognize the Required Rights (provided that QWEST has made timely and
reasonable commercial efforts to obtain the same), or any other cause beyond the
reasonable control of such party. The party claiming relief under this Article
shall notify the other in writing of the existence of the event relied on and
the cessation or termination of said event, and the party claiming relief shall
exercise reasonable commercial efforts to minimize the time of any such delay.


                                   ARTICLE 21

                               DISPUTE RESOLUTION

         21.1     Except as provided in Sections 18.1 and 18.2, if the parties
are unable to resolve any disagreement or dispute arising under or related to
this Agreement, including without limitation, the failure to agree upon any item
requiring a mutual agreement of the parties hereunder, they shall resolve the
disagreement or dispute by arbitration as prescribed in this Section. The
Federal Arbitration Act, 9 U.S.C. Sections 1-15, not state law, shall govern the
arbitrability of all claims.

         21.2     A single arbitrator engaged in the practice of law who is
knowledgeable about the subject matter of this Agreement shall conduct the
arbitration under the then current rules of the American Arbitration Association
(the "AAA"). The arbitrator shall be selected in accordance with AAA procedures
from a list of qualified people maintained by the AAA. The arbitration shall be
conducted in the regional AAA office in Chicago, Illinois, and all expedited
procedures prescribed by the AAA rules shall apply.

         21.3     There shall be no discovery other than the exchange of
information which is provided to the arbitrator by the parties. The arbitrator
shall have authority only to award compensatory damages and shall not have
authority to award punitive damages, other noncompensatory damages or any other
form of relief; the parties hereby waive all rights to any claims for relief
other than compensatory damages. The arbitrators' fees and other costs of the
arbitration shall be borne by the party against whom the award is rendered,
except as the arbitrator may otherwise provide in a written opinion. The
arbitrator shall apply the substantive laws of the State of New York and the
terms and conditions of this Agreement, and shall make written findings of fact
and conclusions of law in support of the award.

         21.4     If any party files a judicial or administrative action
asserting claims subject to arbitration as prescribed herein, and another party
successfully stays such action or compels arbitration of said claims, the party
filing said action shall pay



                                      -12-


   13


the other party's costs and expenses incurred in seeking such stay or compelling
arbitration, including reasonable attorneys' fees.

                       ASSIGNMENT AND DARK FIBER TRANSFERS

         22.1     Except as provided below, QWEST shall not assign, encumber or
otherwise transfer this Agreement or all or any portion of its rights or
obligations hereunder to any other party without the prior written consent of
NETWORK, which consent will not be unreasonably withheld or delayed.
Notwithstanding the foregoing, QWEST shall have the right, without NETWORK's
consent, to (a) subcontract any of its construction or maintenance obligations
hereunder, or (b) assign or otherwise transfer this Agreement in whole or in
part (1) as collateral to any institutional lender to QWEST (or institutional
lender to any permitted transferee or assignee of QWEST) subject to the prior
rights and obligations of the parties hereunder, (2) to any parent, subsidiary
or affiliate of QWEST, (3) to any person, firm or corporation which shall
control, be under the control of or be under common control with QWEST, or (4)

or which purchases all or substantially all of the stock or assets of QWEST;
PROVIDED THAT the assignee or transferee in any such circumstance shall continue
to be subject to all of the provisions of this Agreement, including without
limitation, this Section 22.1 (except that any lender referred to in clause
(b)(1) above shall not incur any obligations under this Agreement nor shall it
be restricted from exercising any right of enforcement or foreclosure with
respect to any related security interest or lien, so long as the purchaser in
foreclosure is subject to the provisions of this Agreement, including, without
limitation, this Section 22.1); and PROVIDED FURTHER THAT promptly following any
such assignment or transfer, QWEST shall give NETWORK written notice identifying
the assignee or transferee. In the event of any permitted partial assignment of
any rights hereunder, QWEST shall remain the sole point of contact with NETWORK.
No permitted partial or complete assignment shall release or discharge QWEST
from its duties and obligations hereunder.

         22.2     Except as provided in this Section 22.2 and the following
Section 22.3, NETWORK shall not assign, encumber or otherwise transfer this
Agreement or all or any portion of its rights or obligations hereunder to any
other party without the prior written consent of QWEST, which consent will not
be unreasonably withheld or delayed. Subject to the provisions of Section 22.3
(which provision shall be binding upon any permitted assignee or transferee
hereunder), NETWORK shall have the right, without QWEST's consent, to assign or
otherwise transfer this Agreement in whole or in part (a) as collateral to any
institutional lender to NETWORK (or institutional lender to any permitted
transferee or assignee of NETWORK) subject to the prior rights and obligations
of the parties hereunder, (b) to any parent, subsidiary or affiliate of NETWORK,
(c) to any person, firm or corporation which shall control, be under the control
of or be under common control with NETWORK, or (d) any other entity into which
NETWORK may be merged or consolidated or which purchases all or substantially
all of the stock or assets of NETWORK; PROVIDED THAT the assignee or transferee
in any such circumstance shall continue to be subject to all of the provisions
of this Agreement, including without limitation this Section 22.2 and the
following Section 22.3 (except that any lender referred to in clause (a) above

from exercising any right of enforcement or foreclosure with respect to any

comprising the Segment as Dark Fibers (any of the foregoing, a "Restricted
Transaction") (or engage in substantive discussions or negotiations with respect
to a Restricted Transaction), or otherwise engage in a similar transaction with
respect to any NETWORK Fibers comprising the Segment in a manner designed or
intended to circumvent the foregoing limitations.

         22.4     This Agreement and each of the parties' respective rights and
obligations under this Agreement, shall be binding upon and shall inure to the
benefit of the parties hereto and each of their respective permitted successors
and assigns.


                                   ARTICLE 23

                 REPRESENTATIONS, WARRANTIES AND ACKNOWLEDGMENTS

         23.1     Each party represents and warrants that:

                  (a)      it has the full right and authority to enter into,
execute, deliver and perform its obligations under this Agreement;

                  (b)      this Agreement constitutes a legal, valid and binding
obligation enforceable against such party in accordance with its terms, subject
to bankruptcy, insolvency, creditors' rights and general equitable principles;
and

                  (c)      its execution of and performance under this Agreement
shall not violate any applicable existing regulations, rules, statues or court
orders of any local, state or federal government agency, court or body.

         23.2     QWEST represents and warrants that the terms of its Agreement
with the THIRD PARTY specifically provide that QWEST may grant an IRU in its
dark fibers to a third party and, further, that the terms of the Required Rights
documents do not preclude the assignment of its fibers to NETWORK.

         23.3     QWEST represents and warrants that the Segment shall be
constructed by the THIRD PARTY substantially and in all material respects in
accordance with the specifications set forth in Exhibit B hereto.

         23.4     EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT QWEST MAKES NO
WARRANTY, EXPRESS OR IMPLIED, WITH RESPECT TO THE NETWORK FIBERS OR THE SEGMENTS
DELIVERABLE HEREUNDER, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR
PARTICULAR PURPOSE, AND ALL SUCH WARRANTIES ARE HEREBY EXPRESSLY DISCLAIMED.

         23.5     The parties acknowledge and agree that on and after the
Acceptance Date NETWORK's sole rights and remedies (as between the parties
hereto) with respect to any defect in or failure of the NETWORK Fibers (other
than any defect or failure caused by the willful or negligent act or omission of
QWEST) to perform in accordance with the applicable vendor's or manufacturer's
specifications with respect to the NETWORK Fibers shall be limited to the
particular vendor's or manufacturer's warranty with respect thereto, which
warranty, to the extent permitted by the terms thereof, shall be assigned to
NETWORK upon its request. In the event any maintenance or repairs to the New
York - Boston Segment are required as a result of a breach of any warranty made
by any manufacturers, contractors or vendors, unless NETWORK shall elect to
pursue such remedies itself, QWEST shall pursue all remedies against such
manufacturers, contractors or vendors on behalf of NETWORK, and QWEST shall
reimburse NETWORK's costs for any maintenance NETWORK has incurred as a result
of any such breach of warranty to the extent the manufacturer, contractor or
vendor has paid such costs.

                                     GENERAL

         24.1     WAIVER. The failure of either party hereto 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.

         24.2     GOVERNING LAW. This Agreement shall be governed by and
construed in accordance with the domestic laws of the State of New York, without
reference to its choice of law principles. Subject to Article 21 hereof, any
litigation based hereon,




                                      -14-


   15


or arising out of or in connection with a default by either party in the
performance of its obligations hereunder, shall be brought and maintained
exclusively in the courts of the State of New York, or in the United States
District Court in New York, and each party hereby irrevocable submits to the
jurisdiction of such courts for the purpose of any such litigation and
irrevocably agrees to be bound by any judgment rendered thereby in connection
with such litigation.

         24.3     RULES OF CONSTRUCTION. The captions or headings in this
Agreement are strictly for convenience and shall not be considered in
interpreting this Agreement or as amplifying or limiting any of its content.
Words in this Agreement which import the singular connotation shall be

                  (a)      Unless expressly defined herein, words having well
known technical or trade meanings shall be so construed. All listing of items
shall not be taken to be exclusive, but shall include other items, whether
similar or dissimilar to those listed, as the context reasonably requires.

                  (b)      Except as set forth to the contrary herein, any right
or remedy of NETWORK or QWEST shall be cumulative and without prejudice to any
other right or remedy, whether contained herein or not.

                  (c)      This Agreement has been fully negotiated between and

                  (d)      All actions, activities, consents, approvals and
other undertakings of the parties in this Agreement shall be performed in a
reasonable and timely manner. Except as specifically set forth herein, for the
purpose of this Agreement the standards and practices of performance within the
telecommunications industry in the relevant market shall be the measure of a
party's performance.

         24.4     ENTIRE AGREEMENT. This Agreement constitutes the entire and
final agreement and understanding between the parties with respect to the
subject matter hereof and supersedes all prior agreements relating to the
subject matter hereof, which are of no further force or effect. The Exhibits
referred to herein are integral parts hereof and are hereby made a part of this
Agreement. To the extent that any of the provisions of any Exhibit hereto are
inconsistent with the express terms of this Agreement, the terms of this
Agreement shall prevail. This Agreement may only be modified or supplemented by

party and delivered to the party relying on the writing.

         24.5     NO PERSONAL LIABILITY. Each action or claim against any party
arising under or relating to this Agreement shall be made only against such
party as a corporation, and any liability relating thereto shall be enforceable
only against the corporate assets of such party. No party shall seek to pierce
the corporate veil or otherwise seek to impose any liability relating to, or
arising from, this Agreement against any shareholder, employee, officer or
director of the other party. Each of such persons is an intended beneficiary of
the mutual promises set forth in this Article and shall be entitled to enforce
the obligations of this Article.

         24.6     RELATIONSHIP OF THE PARTIES. The relationship between NETWORK
and QWEST shall not be that of partners, agents, or joint venturers for one
another, and nothing contained in this Agreement shall be deemed to constitute a
partnership or agency agreement between them for any purposes, including, but
not limited to federal income tax purposes. NETWORK and QWEST, in performing any
of their obligations hereunder, shall be independent contractors or independent
parties and shall discharge their contractual obligations at their own risk
subject, however, to the terms and conditions hereof. 

         24.7     SEVERABILITY. If any term, covenant or condition contained
herein is, to any extent, held invalid or unenforceable in any respect under the
laws governing this Agreement, the remainder of this Agreement shall not be
affected thereby, and each term, covenant or condition of this Agreement shall
be valid and enforceable to the fullest extent permitted by law.

         24.8     COUNTERPARTS. This Agreement may be executed in one or more
counterparts, all of which taken together shall constitute one and the same
instrument.
