     THIS IRU AGREEMENT (this "Agreement") is made and entered into as of
October 18, 1996, by and between QWEST COMMUNICATIONS CORPORATION, a Delaware
corporation ("QWEST"), and FRONTIER COMMUNICATIONS INTERNATIONAL INC. a Delaware
corporation ("FRONTIER").

                                    RECITALS
                                    --------

     A.  QWEST is planning to construct a continuous fiberoptic communication
system, contiguous from end to end, as described in Exhibit A hereto as the
"Basic Route," and between each of the city pairs identified in Exhibit A-1
hereto under the caption "Basic Route" (the fiberoptic communication system
between each such city pair being referred to as a "Basic Segment"), and may
elect to construct a continuation of such fiberoptic communication system along
the routes described in Exhibit A hereto as the "Option 1 Route," "Option 1A
Route" and the "Option 2 Route" (collectively, the "Optional Routes"), and
between each of the city pairs identified in Exhibit A-1 hereto under the
captions "Option 1 Route," "Option 1A Route" and "Option 2 Route" (the
fiberoptic communication system between each such city pair being referred to as
an "Optional Segment") (the Basic Segments, together with such of the Optional
Segments, if any, that QWEST elects to construct hereunder, being referred to
herein collectively as the "QWEST System").

     B.  FRONTIER desires to be granted the right to use (or, if and to the
extent provided in Section 1.5 hereof, to own) certain optical fibers in the
QWEST System.

     C.  QWEST desires to grant FRONTIER an exclusive, indefeasible right to use
(or, if and to the extent provided in Section 1.5 hereof, to convey title to)
certain fibers and associated property in the QWEST System, all upon the terms
and conditions set forth below.

     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 I.

                          GRANT OF IRU IN QWEST SYSTEM
                          ----------------------------

     1.1  (a)  Effective as of the effective date described in Section 6.1
below, for each particular Segment (as defined below in this Section 1.1)
delivered by QWEST to FRONTIER hereunder and with respect to which an Acceptance
Date (as defined in Section 4.2 below) has occurred, QWEST hereby grants to
FRONTIER, and FRONTIER hereby purchases from QWEST, (i) an exclusive,
Indefeasible Right of Use (as defined in Section 33.1(f)) (or, if and to the
extent provided in Section 1.5 hereof, ownership) in, for the purposes described
herein, twenty-four (24) (or, if and to the extent that FRONTIER timely 
exercises the options described in Section  below, forty-eight (48))
"Dark Fibers" (as defined in Section 33.1(c)) to be
specifically identified, in the QWEST System (A) in the Basic Segments and along
the Basic Route more specifically described in the maps included in Exhibit A-3
hereto; and (B) if, pursuant to Section 1.3, QWEST elects, in its discretion, to
construct either of Option Route 1 or Option Route 1A, and/or Option Route 2, or
FRONTIER elects, in its discretion, to require QWEST to construct Option Route
1, in any case as identified in Exhibit A (and along the Option 1, Option 1A and
Option 2 Routes more specifically described in the maps included in Exhibit A-3
hereto), in the Optional Segments included in any such Optional Routes so
elected to be constructed, and (ii) an associated and non-exclusive Indefeasible
Right of Use, for the purposes described herein, in the tangible and intangible
property needed for the use of such Dark Fibers as Dark Fibers, including, but
not limited to, the associated conduit, QWEST's rights in all "Underlying
Rights" (as defined in Section 10.1) and, to the extent provided in Article VII
herein, associated Regeneration Facilities (as defined in Section 7.2), but in
any event excluding any electronic or optronic equipment (collectively, the
"Associated Property"), for the Term (as defined in Section 6.1) respecting such
Basic Segment or Optional Segment, and all on the terms and subject to the
covenants and conditions set forth herein (collectively, the "IRUs"). The Dark
Fibers subject to the IRUs are referred to collectively as the "FRONTIER
Fibers." The Basic Segments, together with such of the Optional Segments, if
any, that QWEST elects or is required to construct pursuant to Section 1.3 are
referred to herein collectively as the "Segments." The Basic Route, together
with such of the Optional Routes, if any, that QWEST elects or is required to
construct pursuant to Section 1.3 are referred to herein collectively as the
"System Route."

     (b) The parties acknowledge and agree that the specific route of any
Segment that has not been finally designed or engineered, or with respect to
which a right-of-way agreement has not been obtained as of the date hereof is
subject to final determination by QWEST, based on specific engineering, right-
of-way, permitting, authorization and other requirements; provided, however,
                                                          ------------------
that (i) any such Segment route, as finally determined, must include all of 
the endpoint and intermediate point cities identified in Exhibit A-4 and all 
of the junction points identified in the System Route maps included in 
Exhibit A; (ii) no deviation in the route of any Segment as set forth in the 
maps included in Exhibit A-3 shall result in a Material Deviation (as defined 
below) in the System Route as set forth in Exhibit A, and (iii) once the final 
route of any Segment has been so determined, QWEST shall deliver to FRONTIER 
corresponding revisions to the relevant maps included in Exhibit A hereto.  
As used herein, the term "Material Deviation" shall mean a deviation in the 
general route of a Segment (A) that modifies the System Route architecture in 
a manner that breaks a ring, creates a spur or breaks the contiguous nature of 
Segments; (B) that modifies the route of the System Route through any city, 
identified in Exhibit A-3 as being the location of a FRONTIER POP site, from 
the detailed route map shown in Exhibit A-3 for such city in a manner that 
materially changes the proximity of such POP site to the System Route right-of-
way (provided that, if any such detailed city map shows that the POP site is 
in direct proximity to the System Route right-of-way, any route modification 
which does not provide such direct proximity shall be considered a material 
change in proximity);

            
(C) that modifies the route of the System Route through any city, as set forth
in the detailed route map for such city set forth in Exhibit A-3, such that the
location of the route at any point would be moved more than 1,200 feet in any
direction, without the prior written approval of FRONTIER (such approval not to
be unreasonably withheld or delayed); or (D) that modifies any parallel route
shown within any city that is the subject of a detailed map included in Exhibit
A-3 such that the distance between such parallel routes is less than 1,200 feet
outside metropolitan areas and less than two city blocks within metropolitan
areas.

     (c) If any deviation(s) in the routes of Segments (i) comprising the Basic
Route and Option Route 1 cause(s) the aggregate route miles as reflected in
Exhibit A estimated for the Basic Route and Option Route 1 taken together to
increase by more than   

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR 
CONFIDENTIAL TREATMENT##

    %) of such aggregate estimate or (ii)
comprising Option Route 1A and/or Option Route 2 cause(s) the route miles as
reflected in Exhibit A estimated for Option 1A and/or Option Route 2 taken
separately to increase by more than  

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR 
CONFIDENTIAL TREATMENT##

    %) of such estimate, then in
each case under the foregoing clause (i) and clause (ii) such mileage shall be
solely at QWEST's cost and expense and any route mileage in excess of the
applicable

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR 
CONFIDENTIAL TREATMENT##

    %) increase as aforesaid shall not be included in the
route mileage for purposes of determining or redetermining the IRU Fee as
defined and described in Section 2.1 below.

     1.2  With respect to Segments 12A, 12B, 12C, 12D and 16, the parties
acknowledge that (i) QWEST has represented that the conduit and Cable comprising
such Segments have been constructed and installed as of the date hereof, and
that only the regeneration and other technical facilities required to be
provided with respect to each such Segment pursuant to Article VII remains to be
constructed and installed, (ii) FRONTIER desires to use the FRONTIER Fibers in
the Cable comprising each such Segment pending delivery of such facilities, and
(iii) the Cable comprising such Segments currently is routed through such
facilities of QWEST.  Accordingly, with respect to Segments 12A, 12B, 12C, 12D
and 16, the parties agree that notwithstanding any provisions of this Agreement
to the contrary:

     (a) Promptly following execution of this Agreement, the Fiber Acceptance
Testing procedures set forth in Article IV shall take place with respect to each
such Segment, as the FRONTIER Fibers currently are routed through the QWEST
facilities and, upon satisfactory completion thereof with respect to each such
Segment in accordance with Article IV, the Acceptance Date with respect to such
Segment shall occur.  Upon such Acceptance Date, payment of an additional   

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR 
CONFIDENTIAL TREATMENT##

    % of
the IRU Fee with respect to such Segment shall be due and payable by FRONTIER.

     (b) Upon receipt of such payment, the IRUs with respect to the relevant
Segment, other than the IRU in the Associated Property required to be delivered
pursuant to Section  7.2, shall become effective.  Thereupon, FRONTIER may
temporarily install in the space within certain QWEST facilities described in
Exhibit G-1 hereto, such electronic, optronic and other
equipment as shall be necessary to operate the FRONTIER Fibers in such Segment;
                                                                               
provided that such installation is done consistent with QWEST's co-location
-------------                                                              
policies and procedures substantially as set forth in the form of co-location
agreement, a copy of which has been provided to and accepted by FRONTIER.

     (c) The Associated Property required to be delivered pursuant to Section
7.2 shall be delivered in accordance with the requirements of Section 3.2 with
respect to each such Segment.  The parties agree to cause their respective
appropriate technical personnel to discuss and agree, in good faith, upon the
procedures by which, upon such delivery, (i) the FRONTIER Fibers comprising such
Segments shall be rerouted, at QWEST's cost and expense, in the Regeneration
Facilities (or POPs or terminal facilities)  required to be provided pursuant to
Article VII, and (ii) tested, at QWEST's cost and expense, to confirm that, as
rerouted, the FRONTIER Fibers continue to operate in conformity with the Fiber
Acceptance Testing specifications set forth in Exhibit D and the procedures set
forth in Article IV.

     (d) Upon the delivery of such Associated Property, the rerouting of the
FRONTIER Fibers therein, and the confirmed testing described in Section
1.3(c)(ii), the remaining 

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR 
CONFIDENTIAL TREATMENT##

    %) of the IRU Fee with respect to each
such Segment shall be due and payable by FRONTIER.  Upon receipt of such
payment, the IRU with respect to such Associated Property for such Segment shall
become effective.

     1.3  (a)  Until 5:00 p.m. Eastern Standard (or Daylight, as applicable)
Time on the date that is one hundred eighty (180) days after the date hereof 
(the "Option Period") (i) QWEST shall have the right to elect to construct and 
(ii) FRONTIER shall have the right to elect to require QWEST to construct, 
Option Route 1.
Either party desiring to exercise such right shall notify the other in writing
by such time and date whether or not it will construct or require the
construction of Option Route 1.  Failure of QWEST to notify FRONTIER of QWEST's
election as to Option Route 1 as provided herein shall be deemed an election by
QWEST not to undertake to construct Option Route 1, and failure of FRONTIER to
notify QWEST of FRONTIER's election as to Option Route 1 as provided herein
shall be deemed an election by FRONTIER not to require that QWEST construct
Option Route 1.  If neither QWEST nor FRONTIER timely exercises its right to
construct or require the construction of Option Route 1 as provided herein,
then, until 5:00 p.m. Eastern Standard (or Daylight, as applicable) Time on the
day that is five (5) days following the last day of the Option Period, QWEST
shall have the right to elect to construct Option Route 1A.  QWEST shall notify
FRONTIER in writing by such time and date whether or not it will construct
Option Route 1A.  Failure of QWEST to notify FRONTIER of QWEST's election as to
Option Route 1A as provided herein shall be deemed an election by QWEST not to
construct Option Route 1A.

     (b) QWEST shall have until 5:00 p.m. Eastern Standard (or Daylight, as
applicable) Time on the last day of the Option Period to elect whether or not it
will construct Option Route 2 as provided herein.  QWEST shall notify FRONTIER
in writing by such time and date whether
or not it will construct Option Route 2 as provided herein.  Failure of QWEST to
timely notify FRONTIER of QWEST's election as to Option Route 2 as provided
herein shall be deemed an election by QWEST not to undertake to construct Option
Route 2 as provided herein.

     (c) The election or deemed election by QWEST not to construct any of the
Optional Routes as provided herein shall not affect its obligations or rights
with respect to the other Optional Routes or any of the Basic Segments and, from
and after any such election or deemed election, neither party shall have any
further rights or obligations with respect to such Optional Route hereunder.

     (d) From the date hereof until the expiration of the parties' rights under
this Section 1.3, FRONTIER shall not enter into any agreement (oral or written)
or initiate discussions or negotiations with any third party with respect to its
acquisition of an alternative Dark Fiber system along the same or similar routes
as any of the Optional Routes, and FRONTIER shall not engage in discussions with
any third party who may initiate the same without prior notice to QWEST of the
identity of such third party given promptly after such initiation by such third
party and prior to FRONTIER's engaging in such discussions with such third
party, and if FRONTIER engages in such discussions as aforesaid then FRONTIER
shall keep QWEST informed generally of the material proposed terms and material
changes to such terms with respect to such discussions relating to an
acquisition by such third party of an alternative Dark Fiber system along the
same or similar routes as any of the Optional Routes.  If QWEST timely exercises
its option hereunder to construct any of the Optional Routes or if FRONTIER
timely exercises its right to require the construction of Option Route 1, in any
such case as provided herein, then FRONTIER and QWEST shall be obligated to
observe and perform their respective obligations hereunder with respect to such
Optional Route, all on the terms and subject to the conditions set forth herein.

     1.4  (a)  FRONTIER shall have an option (the "System Fiber
Option"), exercisable until 5:00 p.m. Eastern Standard (or Daylight,
as applicable) Time on the date that is one hundred eighty-six (186)
days after the date hereof (the "System Option Exercise Date"), to
elect to increase the number of Dark Fibers subject to the IRU in the
entire QWEST System to be delivered hereunder (including the Optional
Segments, if and to the extent QWEST elects to construct the Optional
Routes or is required to construct Option Route 1 pursuant to
Section 1.3 hereof) from twenty-four (24) to forty-eighty (48) Dark
Fibers (such additional twenty-four (24) Dark Fibers being referred to
as the "Optional System Dark Fibers"), by delivering written notice of
such election to QWEST by such time and date.  If FRONTIER timely
exercises the System Fiber Option, the IRU Fee with respect to all
Segments shall be redetermined as described in Section 2.1(b) below.

          (ii) If, prior to the System Option Exercise Date, QWEST
enters into an agreement with the party (or the successor in interest
of such party or a subsidiary of such party) with whom QWEST and
FRONTIER previously have engaged in extensive discussions concerning
the provision by QWEST of a forty-eight (48) Dark Fiber system along
the QWEST System (the "Third Party"), pursuant to which QWEST grants
to the Third Party an IRU in twenty-four (24) Dark Fibers along some
or all of the QWEST System, QWEST shall promptly notify FRONTIER
thereof.  In such event, FRONTIER may, at its election and at its sole
discretion, at any time on or before the Option Exercise Date (A) if
the Third Party acquires Dark Fibers along the entire QWEST System,
elect to cancel the System Fiber Option in its entirety, in
consideration for which the IRU Fee for all Segments shall be
redetermined as described in Section 2.1(c) below, (B) if the Third
Party acquires Dark Fibers in Segments comprising less than all of the
QWEST System, elect to exercise the System Fiber Option only with
respect to the Segments not so acquired by the Third Party and to
cancel the System Fiber Option with respect to the Segments acquired
by the Third Party, in consideration for which the IRU Fee with
respect to all Segments shall be redetermined as described in
Section 2.1(d) below, or (C) in any event, elect to exercise the
System Fiber Option in its entirety pursuant to Section 1.4(a)(i),
unaffected by QWEST's transaction with the Third Party.

          (iii)     Failure of FRONTIER to timely notify QWEST of
FRONTIER's election to exercise the System Fiber Option in whole or,
as permitted, in part, as provided herein, shall be deemed an election
by FRONTIER not to exercise the System Fiber Option.  The election or
deemed election of FRONTIER not to exercise the System Fiber Option
shall not affect either party's rights or obligations with respect to
the twenty-four (24) Dark Fiber QWEST System to be provided hereunder
and, from and after any such election or deemed election, neither
party shall have any further rights or obligations with respect to the
Optional System Dark Fibers hereunder.

     (b) FRONTIER shall have an option (the "Sacramento/Seattle Fiber
Option"), exercisable until 5:00 p.m. Eastern Standard (or Daylight,
as applicable) Time on the date that is thirty (30) days after the
date hereof, to elect to increase the number of Dark Fibers subject to
the IRU in the Segments between the cities of Sacramento, California
and Seattle, Washington identified in Exhibit A (the
"Sacramento/Seattle Segments") from twenty-four (24) to forty-eight
(48) Dark Fibers (such additional twenty-four (24) Dark Fibers being
referred to as the "Optional Sacramento/Seattle Dark Fibers"), by
delivering written notice of such election to QWEST by such time and
date.  If FRONTIER timely exercises the Sacramento/Seattle Fiber
Option, the IRU Fee with respect to the Sacramento/Seattle Segments
shall be redetermined as described in Section 2.1(e) below. 
Notwithstanding the foregoing, FRONTIER acknowledges that the
Sacramento/Seattle Fiber Option is not to be redundant of the System
Fiber Option and, accordingly, (i) the Sacramento/Seattle Fiber Option
automatically shall be canceled if FRONTIER exercises the System Fiber
Option or cancels the System Fiber Option pursuant to Section
1.4(a)(ii), and (ii) the maximum number of Dark Fibers deliverable by
QWEST to FRONTIER with respect to either or both of the
Sacramento/Seattle Fiber Option and the System Fiber Option shall not
exceed forty-eight (48) Dark Fibers along the applicable route. 
Failure of FRONTIER to timely notify QWEST of FRONTIER's election to
exercise the Sacramento/Seattle Fiber Option as provided herein shall
be deemed an election by FRONTIER not to exercise the
Sacramento/Seattle Fiber Option.  The election or deemed election of
FRONTIER not to exercise the Sacramento/Seattle Fiber Option shall not
affect either party's rights or obligations with respect to the
twenty-four (24) Dark Fibers in the Sacramento/Seattle Segments to be
provided hereunder and, from and after any such election or deemed
election, neither party shall have any further rights or obligations
with respect to the Optional Sacramento/Seattle Dark Fibers hereunder.

     1.5  Notwithstanding anything contained herein to the contrary:  (a) if and
to the extent allowed by the Underlying Right(s) for a particular Segment, and
(b) if the Underlying Right(s) with respect to such Segment do not and will not
impose upon QWEST any additional fees, costs or charges as a result thereof
(unless FRONTIER shall pay the same or make arrangements satisfactory to QWEST
to assure such payment), QWEST shall, upon the request of FRONTIER and on a
Segment-by-Segment basis on or before the Acceptance Date with respect to such
Segment:  (i) grant a non-exclusive sub-easement, sub-right of way, or sub-
underlying right  (collectively a "Sub-Easement") to FRONTIER providing rights
(but, subject to the foregoing clause (b) of this Section 1.5 above, at no
additional cost to or monetary obligations of FRONTIER) to FRONTIER similar to
the rights held by QWEST under the relevant Underlying Right(s), and (ii)
transfer title to the Frontier Fibers to FRONTIER free and clear of all liens as
provided in Section 11.4 hereof, and (iii) continue the grant of the IRU in the
Associated Property.  Nothing in this Section 1.5 shall relieve QWEST or
FRONTIER of its (nor, except and only to the extent of the change in the nature
of the property interest of FRONTIER in the FRONTIER Fibers or a Sub-Easement,
or the case may be, diminish, enlarge or otherwise affect its) rights, duties
and obligations set forth in this Agreement and if any Sub-Easement shall
terminate or FRONTIER shall be otherwise prohibited from owning title to the
Frontier Fibers, QWEST shall retain, maintain or replace the relevant Underlying
Right in accordance with and pursuant to Article X, title to such Frontier
Fibers shall revert and be reconveyed to QWEST and FRONTIER shall have and
retain the IRU in such Frontier Fibers under and subject to the terms and
conditions of this Agreement.  If a Sub-Easement is granted or title to the
FRONTIER Fibers transferred to FRONTIER  in accordance with the foregoing
provisions of this Section 1.5, then such Sub-Easement shall terminate and such
title shall revert and be reconveyed to QWEST at the expiration or termination
of the Term respecting the applicable Segment as provided in and pursuant to
Article VI hereof.

                                  ARTICLE II.

                            CONSIDERATION FOR GRANT
                            -----------------------

     2.1  In consideration of the grant of the IRUs hereunder by QWEST to
FRONTIER, FRONTIER agrees to pay to QWEST an IRU fee determined based on the
QWEST System route
mileage (and allocated among the Segments based on Segment route mileage) as
follows (the "IRU Fee"):

     (a) Initially, the IRU Fee shall be determined based on the following per-
route-mile pricing:

          (i) $

slack).

     (b) In the event that FRONTIER receives a bona fide quote from a fiberoptic
cable vendor to provide the same fiberoptic cable that QWEST would acquire to
install in a Segment hereunder in accordance with the QWEST System design and
the fiber deployment plan and fiber specification requirements provided herein,
at a price (including the business terms, handling charges and similar
incidental charges) lower than        

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR 
CONFIDENTIAL TREATMENT##

          the best price available to QWEST for
such fiberoptic cable, FRONTIER shall notify QWEST in writing thereof,
identifying the vendor, the quoted price, and the type and quantity of
fiberoptic cable subject to such quote (each, a "Fiber Quote Notice"), such that
QWEST may attempt to acquire such fiberoptic cable at such price from such
vendor.  If QWEST is able to acquire fiberoptic cable from the vendor and at the
price set forth in a Fiber Quote Notice for inclusion in a Segment or Segments
delivered hereunder, FRONTIER shall receive a credit against amounts
subsequently payable by FRONTIER hereunder equal to 

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR 
CONFIDENTIAL TREATMENT##

    %) of the
difference between the best price available to QWEST for such fiberoptic cable
and the price obtained from such vendor pursuant to the Fiber Quote Notice (the
"Fiber Savings Credit") for the entire fiberoptic cable so acquired by QWEST for
inclusion in such Segment or Segments.  If QWEST is unable, for any reason, to
acquire fiberoptic cable from the vendor identified in the Fiber Quote Notice or
any other vendor at the price set forth in the Fiber Quote Notice then the
foregoing provisions of this paragraph (b) shall have no further force and
effect and QWEST shall acquire fiberoptic cable through its own sources, subject
to paragraph (a) of this Section 2.2.

     (c) Notwithstanding the foregoing provisions of paragraphs (a) and (b) of
this Section 2.2, no such reimbursement or credit shall be required with respect
to any fiberoptic cable including FRONTIER Fibers that, as of the date hereof,
has already been installed or
delivered to QWEST for installation in the QWEST System or is subject to a
binding purchase order for delivery to QWEST for installation in the QWEST
System.  The amount of any such reimbursement or credit shall be invoiced or
credited, as appropriate, to FRONTIER at the time the fiberoptic cable
incorporating such FRONTIER Fibers is invoiced to QWEST.  FRONTIER and QWEST
agree to reasonably consult and cooperate with each other in order to obtain the
lowest possible price for fiberoptic cable to be included in a Segment.
FRONTIER also shall pay directly or reimburse QWEST for all other costs, fees
and expenses which are expressly provided to be paid, in whole or in part, by
FRONTIER under this Agreement.  FRONTIER shall have  the right to review and
audit, at its cost, all such costs, fees and expenses.

     2.3  QWEST will fax or send by overnight delivery each invoice for payments
to be made by FRONTIER hereunder.  FRONTIER shall pay such invoiced amounts,
less any reasonably disputed amounts, for receipt by QWEST within fifteen (15)
days after receipt of such invoice by FRONTIER with respect to payments of the
IRU Fee and within thirty (30) days after receipt of such invoice by FRONTIER
for any other amounts owed to QWEST hereunder; provided that FRONTIER shall
                                               -------------               
provide written notice describing in detail the basis for any disputed amounts;
and provided further that any disputed amounts that are resolved in favor of
    ---------------------                                                   
QWEST shall be due for payment based on the original invoice date.  All payments
to be made by FRONTIER hereunder of the IRU Fee and of any other amounts in
excess of $100,000 shall be made by wire transfer of immediately available funds
to the account or accounts as QWEST shall notify FRONTIER in writing from time
to time.  Payments of all other amounts by FRONTIER hereunder may be made by
check payable to QWEST.  QWEST agrees to provide FRONTIER from time to time,
upon request, with QWEST's estimate of the next invoice date for a portion of
the IRU Fee and the estimated amount of such IRU Fee payment; provided that
                                                              -------------
failure to provide any such notice shall not in any way alter or impair
FRONTIER's payment obligations hereunder.

     2.4  QWEST and FRONTIER acknowledge and agree that with respect to Segment
23, notwithstanding the fact that Segment 23 has already been constructed and
installed, delivery of Segment 23 shall occur in two installments of twelve (12)
Dark Fibers each as indicated in Exhibit A, and payment of the IRU Fee therefor
(other than the initial   

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR 
CONFIDENTIAL TREATMENT##

    % due upon execution of this Agreement), shall be
deferred until each such deferred installment delivery date as set forth in
Exhibit B.  QWEST and FRONTIER further acknowledge and agree that with respect
to Segments 24A, 24B, 24C, 24D, 24E and 25, once constructed and installed,
delivery of each such Segment likewise shall occur in two installments of twelve
(12) Dark Fibers each as indicated in Exhibit A, and payment of the IRU Fee
therefor shall be made as set forth in Exhibit B.

     2.5  QWEST and FRONTIER acknowledge and agree that with respect to Segments
5, 6, 9A, 9B, 10A and 10B, notwithstanding the payment schedule set forth in
Exhibit B and the fact that the conduit in such Segments has already been
constructed and
installed, FRONTIER shall be required to pay with respect to each of those
Segments:  (a)   

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR 
CONFIDENTIAL TREATMENT##

    % of the IRU Fee upon execution of this Agreement, (b)   

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR 
CONFIDENTIAL TREATMENT##

    % of the
IRU Fee when (i) QWEST has commenced the placement of the Cable in the Segment,
and (ii) all such Cable and other materials necessary to complete such placement
within a reasonable time are on hand or scheduled for timely delivery in
connection with such placement, and (c) the balance of the IRU Fee in accordance
with the provisions of Exhibit B.

     2.6  All of FRONTIER's payment obligations under this Agreement shall be
guaranteed by Frontier Corporation pursuant to a Guaranty in the form of Exhibit
K hereto, to be executed and delivered by Frontier Corporation as a condition to
the effectiveness hereof and the performance by QWEST of its obligations
hereunder.

                                  ARTICLE III.

                        CONSTRUCTION OF THE QWEST SYSTEM
                        --------------------------------

     3.1  QWEST shall, at QWEST's sole cost and expense, be responsible for and
shall effect the design, engineering, installation, and construction of those
portions of the QWEST System not already constructed as of the date hereof in
accordance with the System Route (as it may be modified pursuant to Section 1.1)
and in conformity with (i) the construction specifications set forth in Exhibit
C, (ii) industry standards and practices, and (iii) applicable Underlying Rights
Requirements (as defined in Section 11.1).  Such responsibilities shall include,
without limitation, preparation of construction drawings, bills of materials,
materials specifications and materials requisitions.  Except for the existing
fibers on Segments 11A, 11B, 12A, 12B, 12C and 12D (which are Corning SMF-DS)
and any alternative fibers approved pursuant to the following sentence, all
fiber included in the FRONTIER Fibers shall be Corning SMF-LS non-zero
dispersion-shifted or Lucent Technologies True Wave and shall meet or exceed the
applicable fiber specifications set forth in Exhibit E.  QWEST may use
alternative types of fiber equivalent to either of the aforementioned fibers;
provided that (i) prior to any such use, QWEST meets with FRONTIER (and 
FRONTIER hereby agrees to so meet) to, cooperatively and in good faith, 
jointly evaluate the use of any such fiber and (ii) thereafter, FRONTIER 
approves the use of such fiber, which approval shall not be unreasonably 
withheld or delayed.  QWEST agrees that, to the extent possible in light of 
the fiber already incorporated in Segments that have been constructed, in 
whole or in part, prior to the date hereof and the availability and cost of 
the fiber of a particular type and manufacture hereafter, fiber utilized 
with respect to the loops, rings and regions of the QWEST System shall be 
of the same type and manufacture, as depicted in the fiber deployment 
diagram set forth in Exhibit E-1 hereto, indicating the type of fiber QWEST 
currently plans to use in each such Segment.
Any deviation from the planned fiber use set forth in the diagram must be
approved by FRONTIER, which approval shall not be unreasonably withheld or
delayed.
    3.2  Subject to extension for delays described in Article XX, QWEST shall
complete at QWEST's sole cost and expense, all construction, installation, and
satisfactory Fiber Acceptance Testing (as defined in Section 4.1) of each of the
Segments, including the provision of such Regeneration Facilities on such
Segment as are required to be provided pursuant to Section 7.2(a), by the
applicable "Estimated Delivery Date" (as defined in Section 33.1(d)) respecting
such Segment.

     3.3  Except as may be provided herein, QWEST shall, at QWEST's sole cost
and expense, procure all materials to be incorporated in and to become a
permanent part of the QWEST System, including, without limitation, the
Regeneration Facilities required to be provided pursuant to Section 7.2(a).

     3.4  QWEST shall, at QWEST's sole cost and expense, obtain all Underlying
Rights and other rights, licenses, permits and authorizations as required
pursuant to Article X hereof.

     3.5  In support of QWEST's obligation to construct the QWEST System
hereunder, QWEST will provide, as a condition to FRONTIER's obligations
hereunder, either (i) so long as the Surety Bond has not been delivered as
provided in clause (ii) below, a guaranty up to a maximum aggregate amount of 
$175 millionby Anschutz Company in favor of FRONTIER of the payment 
obligations of QWEST under this Agreement pursuant to a Guaranty in the form 
of Exhibit L or (ii) six (6) surety bonds in favor of FRONTIER, each 
substantially in the form of and by the surety companies identified on 
Exhibit I hereto or such other companies rated "A" or better by Best's Key 
Rating Guide, which, in the aggregate, shall provide a total aggregate payment 
value of not less than $175 million (collectively, the "Surety Bond"), in 
each case clause (i) and (ii) over the entire construction period for all 
Segments to be delivered hereunder.

     3.6  QWEST shall perform, at QWEST's sole cost and expense, substantially
in accordance with industry standards and practices and as deemed necessary or
appropriate in QWEST's reasonable business judgment, all supervisory and
inspection services relating to the construction of the QWEST System, including,
without limitation, performing construction inspections to assure that all
construction shall be in material compliance with the specifications, drawings,
Underlying Rights, provisions of this Agreement, and applicable governmental
codes.  During the course of construction of each Segment, QWEST shall prepare
and provide to FRONTIER construction schedule and progress reports every two
weeks.  FRONTIER shall have the right, but not the obligation, to inspect the
construction of each Segment, including the installation, splicing and testing
of the FRONTIER Fiber incorporated therein, during the course and at the time of
the relevant design, construction and installation period.  No inspection or
failure to inspect by FRONTIER shall impair or invalidate any rights and
remedies of FRONTIER under this Agreement or modify, amend or otherwise affect
any of the representations, warranties, covenants or agreements of QWEST under
this Agreement.

     3.7  Upon FRONTIER's written request, QWEST shall make available for
inspection by FRONTIER, at QWEST's offices, copies of all information,
documents, agreements, reports, permits, drawings and specifications generated,
obtained or acquired by QWEST in performing its duties pursuant to this Article
III that are material to grant of the IRUs to FRONTIER, including, without
limitation, the Underlying Rights, subject only to the conditions that (i) the
terms of each such document or the legal restrictions applicable to such
information or document permits disclosure; provided that QWEST will use its
                                            -------------                   
best efforts (without requiring the expenditure of money) to obtain a waiver of
any existing confidentiality and/or non-disclosure restrictions, and to exempt
FRONTIER from subsequent confidentiality and/or non-disclosure restrictions,
that would restrict QWEST's ability to make such documents and/or information
available to FRONTIER for inspection; (ii) notwithstanding the existence or non-
existence of such restrictions and/or waivers, QWEST may, in its sole
discretion, redact portions of such documents it deems proprietary business
terms prior to FRONTIER's inspection.  No inspection or failure to inspect by
FRONTIER shall impair or invalidate any rights and remedies of FRONTIER under
this Agreement or modify, amend or otherwise affect any of the representations,
warranties, covenants or agreements of QWEST under this Agreement.

     3.8  QWEST shall use reasonable efforts to construct all of Segment 13C of
the Basic Route within the territorial confines of the United States, using its
reasonable efforts and reasonably cooperating with FRONTIER to determine a
construction method, including a powerline build or other alternative, in each
case that would be reasonably cost effective within the overall QWEST System
design.  If, notwithstanding such efforts and cooperation, no such alternative
construction method is mutually agreed upon, then QWEST may construct the
portion of such Segment as shown in Exhibit A-2 in Mexico.

                                  ARTICLE IV.

                   ACCEPTANCE AND TESTING OF FRONTIER FIBERS
                   -----------------------------------------

     4.1  QWEST shall test all FRONTIER Fibers in accordance with the procedures
specified in Exhibit D ("Fiber Acceptance Testing") to verify that the FRONTIER
Fibers are installed and operating in accordance with the specifications
described in Exhibit D.  Fiber Acceptance Testing shall progress span by span
along each Segment as cable splicing progresses, so that test results may be
reviewed in a timely manner.  QWEST shall provide FRONTIER at least five (5)
days advance notice of the date and time of each Fiber Acceptance Testing such
that FRONTIER shall have the right, but not the obligation, to have a person or
persons present to observe QWEST's Fiber Acceptance Testing.  When QWEST has
determined that the results of the Fiber Acceptance Testing with respect to a
particular span show that the FRONTIER Fibers so tested are installed and
operating in conformity with the applicable specifications set forth in Exhibit
D,  QWEST shall promptly provide FRONTIER with a copy of such test results.

     4.2 When QWEST reasonably determines in good faith that the FRONTIER Fibers
with respect to an entire Segment are installed and operating in conformity with
the applicable  specifications set forth in Exhibit D, QWEST shall promptly
provide written notice of same to FRONTIER (a "Completion Notice").  FRONTIER
shall, within thirty (30) days of receipt of the Completion Notice, either
reject the Completion Notice specifying, in good faith, the defect or failure in
such Fiber Acceptance Testing or give QWEST written notice of acceptance of such
Fiber Acceptance Testing (the period from the date of FRONTIER's receipt of the
Completion Notice to the date of QWEST's receipt of FRONTIER's notice of
rejection or acceptance being referred to herein as the "FRONTIER Review
Period").  In the event FRONTIER rejects the Completion Notice, QWEST shall
promptly, and not later than seven days, and at no cost to FRONTIER, commence to
remedy the defect or failure.  Thereafter QWEST shall again give FRONTIER a
Completion Notice with respect to such FRONTIER Fibers.  The foregoing procedure
shall apply again and successively thereafter for a total of two attempts to
remedy the defect or failure.  If QWEST fails to adequately remedy or complete
the defect or failure after two attempts, FRONTIER shall have the right to
proceed promptly and in an economically efficient manner to cure such defects or
failures at QWEST's cost and expense, which shall be paid by QWEST to FRONTIER
upon demand, or at the election of FRONTIER, offset from any IRU Fee payable by
FRONTIER to QWEST with respect to such Segment or any other Segment.  No
acceptance of, or failure by FRONTIER to reject, the Completion Notice shall be
deemed to be a waiver of any rights or remedies of FRONTIER under this
Agreement; provided that, any failure by FRONTIER to timely reject as set forth
           -------------                                                       
above shall operate as a constructive acceptance for purposes of this Agreement.
The date when FRONTIER accepts or is deemed to have accepted a Completion Notice
or cures such defects at QWEST's cost and expense as provided above with respect
to a Segment is herein defined as the "Acceptance Date".

                                   ARTICLE V.

                                 DOCUMENTATION
                                 -------------

     5.1  QWEST shall provide FRONTIER with a copy of all Underlying Right
Requirements (as defined in Section 11.1) applicable to each Segment promptly
following the grant to QWEST of the Underlying Right pursuant to which such
Underlying Right Requirements are imposed and, in any event, on or before the
date of completion of conduit installation in such Segment (as defined in
Exhibit B, paragraph 6(ii)).

     5.2  Not later than ninety (90) days after the Acceptance Date for each
Segment, QWEST shall provide FRONTIER with the following documentation:

     (a) As-built drawings for such Segment in accordance with the requirements
described in Exhibit C ("As-Builts").

     (b) Technical specifications of the optical fiber cable and associated
splices and other equipment placed in that Segment.
 
     5.3  As a condition to, and effective upon receipt of, each IRU Fee payment
installment that is due upon QWEST's achievement of a construction,
installation, testing or acceptance milestone as set forth in Exhibit B, QWEST
shall deliver to FRONTIER a lien waiver with respect to liens in favor of QWEST
arising out of QWEST's services in accomplishing such milestone.  Promptly
following QWEST's receipt of each such payment, QWEST shall use reasonable
efforts to obtain (and in any event on or before the Acceptance Date with
respect to the relevant Segment shall obtain) from each subcontractor that
provided services in accomplishing such milestone a lien waiver with respect to
liens arising out of such services and, upon receipt, deliver a copy of each
such lien waiver to FRONTIER.

                                  ARTICLE VI.

                                      TERM
                                      ----

     6.1  Except to the extent expressly modified by Section 1.2 with respect to
the Segments identified therein, the grant of the IRUs hereunder with respect to
each Segment shall become effective on the first day when both (i) the
Acceptance Date with respect to that Segment has occurred and (ii) QWEST has
received payment in full of the IRU Fee with respect to such Segment in
accordance with Exhibit B, and, subject to the provisions of Article X, such
grant shall terminate at the end of the economically useful life of the FRONTIER
Fibers, as reasonably determined by FRONTIER pursuant to Section 6.2 below.  The
period of each such grant respecting each such Segment and IRU is herein defined
as the "Term".

     6.2  In the event that FRONTIER, at any time, reasonably determines that
the FRONTIER Fibers comprising any Segment have reached the end of their
economically useful life and desires to not retain the IRU in such Segment,
FRONTIER shall have the right to abandon the IRU with respect to such Segment by
written notice to QWEST.  If, at any time during or after the last year of the
Minimum Period (as defined in Section 10.2(ii) below), with respect to any
Segment, FRONTIER fails to use any of the FRONTIER Fibers comprising such
Segment 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 XX or
as a result of QWEST System 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 have the right to request FRONTIER to
acknowledge that the FRONTIER Fibers comprising such Segment have reached the
end of their economic life and, accordingly, has abandoned the FRONTIER Fibers
comprising such Segment (which acknowledgment shall not be unreasonably withheld
or delayed).  Upon any such notice of abandonment or acknowledgment, the Term
shall expire with respect to such Segment and all rights to 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
FRONTIER shall have no further rights or obligations hereunder with respect to
such Segment (subject to the provisions of Article XIX).
 
     6.3  It is understood and agreed as between the parties that the grant of
the IRUs hereunder shall be treated for accounting and federal and all
applicable state and local tax purposes as the sale and purchase of the FRONTIER
Fibers and a corresponding interest in QWEST's rights in the Associated Property
subject thereto, and that on and after the Acceptance Date with respect to each
Segment, FRONTIER shall be treated as the owner of the FRONTIER Fibers and an
interest in QWEST's rights in the Associated Property comprising such 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 (as such term is defined in Section 33.1(e)) on such
basis and, except as otherwise required by law, not to take any positions
inconsistent therewith.  QWEST shall retain legal title to the entire QWEST
System (except if and to the extent provided in Section 1.5), including the
FRONTIER Fibers and Associated Property subject to the IRUs hereunder.  Each
party agrees to indemnify the other with respect to any late filing penalties,
interest or fees incurred as a result of such party's failure to provide the
other with such information solely in such party's possession or control that
may be necessary in order to timely make any such filing.

     6.4  This Agreement shall become effective on the date hereof and shall
terminate on the date when, after completion and delivery of all Segments
required to be delivered hereunder, all the Terms of all such Segments shall
have expired; provided that, those provisions of this Agreement which, by their
              -------------                                                    
express terms, are intended to survive such termination, shall survive.

                                  ARTICLE VII.

                    NETWORK ACCESS; REGENERATION FACILITIES
                    ---------------------------------------

     7.1  (a)  QWEST shall provide FRONTIER with access to, and FRONTIER shall
have the right to connect, at FRONTIER's sole cost and expense, its
telecommunications system with, the FRONTIER Fibers at various network access
points on the QWEST System right-of-way in each of the endpoint cities and
intermediate point cities along the route of each Segment and at such additional
locations along the QWEST System right-of-way as may be requested by FRONTIER
(each such access point being referred to as a "Connecting Point").  The
specific locations of each such Connecting Point shall be as mutually reasonably
agreed upon by the parties in good faith, subject to the Underlying Rights
Requirements and QWEST obtaining other required permits, authorizations and
approvals (which QWEST agrees to use its best efforts to obtain).  Any such
connection will be performed by QWEST, at FRONTIER's sole cost and expense, in
accordance with QWEST's applicable specifications and operating procedures.
FRONTIER shall pay QWEST's Costs for each such connection within thirty (30)
days of the date of FRONTIER's receipt of QWEST's invoice therefor.  In order to
schedule a connection of this type, FRONTIER shall request and coordinate such
work not less than ninety (90) days in advance of the date the connection is
requested to be completed.  Such work will be restricted to a Planned System
Work Period ("PSWP"), as defined in Section 33.1(i), unless otherwise agreed to
in writing for specific projects.  Subject to all applicable Underlying Rights
Requirements, FRONTIER shall also be provided reasonable access by QWEST to any
Connecting Point at all times.  FRONTIER shall have no limitations on the 
types of electronics or technologies employed to utilize the FRONTIER 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 the QWEST System.

     (b) QWEST may route the FRONTIER 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
FRONTIER's use of the FRONTIER Fibers or Associated Property hereunder and QWEST
is responsible for all costs and expenses associated therewith.

     7.2  (a)  The IRU Fee includes QWEST's provision to FRONTIER for its use as
permitted hereunder of      

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR

Option Route 2, depending upon which of the Optional Routes are elected or 
required to be constructed pursuant to Section 1.3 hereof)       
to be located at approximately sixty (60) mile intervals along the QWEST System
right-of-way, in each case consisting of and providing space of approximately
  

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR 
CONFIDENTIAL TREATMENT##

       square feet and amenities (except for the operating costs associated
therewith expressly required to be paid by FRONTIER pursuant to Section 8.2), as
described in Exhibit F ("Regeneration Facilities").  The parties acknowledge
that (i) the locations of such Regeneration Facilities shall be coincident with
the locations of QWEST's own Regeneration Facilities (and located at
approximately 60-mile intervals), the locations of which QWEST shall notify
FRONTIER with sufficient time (no less than ten working days) for FRONTIER to
request a different location for any given facility, in which case the parties
shall mutually agree on a mutually acceptable location for such facility, and
(ii) Exhibit G sets forth the estimated number of such Regeneration Facilities
by Segment, with the locations of such Regeneration Facilities being subject to
final determination of the route of the applicable Segment, space and power
availability and all applicable Underlying Rights Requirements.  In addition,
QWEST shall provide to FRONTIER at FRONTIER's Prorated Cost (as defined below in
this paragraph (a)) POP or terminal facilities of approximately     

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR 
CONFIDENTIAL TREATMENT##

       square
feet along the QWEST System right-of-way at such locations as may be mutually
determined by FRONTIER and QWEST, subject to space and power availability and
Underlying Rights Requirements        

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR 
CONFIDENTIAL TREATMENT##

         subject to space and power
availability and underlying Rights Requirements.  FRONTIER's occupancy of and
access to all such Regeneration Facility Sites (or POP or terminal facilities)
shall include separate, secured, 24-hour-per-day building access.  Any
Regeneration Facilities (or POP or terminal facilities) provided by QWEST to
FRONTIER        

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR 
CONFIDENTIAL TREATMENT##

          with respect to any of the Basic Route and the applicable
Optional Routes shall be at FRONTIER's Prorated Cost.  For purposes of the
foregoing two sentences, FRONTIER's Prorated Cost for Regeneration Facilities
means $    

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR 
CONFIDENTIAL TREATMENT##

       per facility and for POP or terminal facilities means $    

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR 
CONFIDENTIAL TREATMENT##

       per
facility, subject to any adjustment (lower or higher) pursuant to Section 7.2(b)
below.

     (b) QWEST heretofore has requested (or promptly after execution of this
Agreement will request) vendors to submit bids (collectively, the "Initial
Bids") that cover all or
substantially all of the proposed Basic Segments of the QWEST System (plus the
Optional Routes as and when included in any bid requests by QWEST) for the
building items listed below (collectively, the "Building Items").  QWEST has
delivered (or promptly after receipt thereof will deliver) to FRONTIER copies of
such Initial Bids.  If the aggregate cost of the Building Items taking the
lowest quoted cost per Building Item (subject to the last sentence of this
paragraph) under any of the Initial Bids (the "Initial Bid Aggregate Cost") is
equal to or less than the aggregate estimated cost for the Building Items set
forth in the table below (the "Estimated Aggregate Cost"), then for 10 business
days thereafter, or if the Initial Bid Aggregate Cost is more than the Estimated
Aggregate Cost, then for 20 business days thereafter, FRONTIER may solicit from
the same or other vendors bids that cover all or substantially all of the Basic
Segments of the QWEST System (plus the Optional Routes as and when included in
any bid requests by QWEST) covering any of the Building Items (the "FRONTIER
Solicited Bids"). Without regard to what Building Items QWEST actually purchases
in connection with construction of the QWEST System, the lowest quoted cost per
Building Item obtained under any of the Initial Bids and the Frontier Solicited
Bids (subject to the last sentence of this paragraph) shall then be used in
place of the cost set forth in the table below for the respective Building Item,
and the allocated percentage of the total cost (which excludes freight and
taxes) attributable to FRONTIER as set forth in the table below shall be applied
accordingly to the recalculated cost.  The aggregate FRONTIER allocation set
forth in the table below shall be recalculated, and the Prorated Cost for
Regeneration Facilities of $    

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR 
CONFIDENTIAL TREATMENT##

      per facility and the Prorated Cost of POPs (and
terminal facilities) of $    

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR 
CONFIDENTIAL TREATMENT##

       per facility shall be increased or decreased, as
appropriate, by the difference between such recalculated aggregate FRONTIER
allocation and $    

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR 
CONFIDENTIAL TREATMENT##

      .  In determining whether a quote represents the "lowest
quoted cost" for any particular Building Item, (i) such quote must meet all of
QWEST's terms and specifications with respect to the applicable Building Item
and (ii) QWEST shall take into account whether and to what extent such quote is
contingent upon any other quote for one or more other Building Items.

For purposes of this Section 7.2(b), the building items in Regeneration
Facilities and/or POPs or terminal facilities, their respective total cost, the
Estimated Aggregate Cost of them and the allocated FRONTIER percentage with
respect to them are as follows:

(c) Payment by FRONTIER of its Prorated Cost, adjusted to give effect to any adjustments (lower or higher) pursuant to Section 7.2(b), for any POP or terminal facilities shall be paid to QWEST upon commencement of the construction of the Segment of which they are a part. Payment by FRONTIER of its Prorated Cost adjusted to give effect to any adjustments (lower or higher) pursuant to Section 7.2(b), for Regeneration Facilities ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## shall be paid to QWEST upon commencement of the construction of the Segment of which they are a part ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## . The foregoing amounts paid by FRONTIER shall be finally trued up, with QWEST reimbursing FRONTIER for any excess and FRONTIER paying QWEST for any deficiency, on (or as soon as thereafter as practicable) the last Acceptance Date with respect to the Basic Segments, the last Acceptance Date with respect to Segments in Option Route 1 or 1-A, and the last Acceptance Date with respect to Segments in Option Route 2, in each case (i) based on the actual number of Regeneration Facilities actually provided by QWEST ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## or POPs (or terminal facilities) with respect to the Basic Route and the applicable Optional Route and (ii) adjusted to give effect to any adjustments (lower or higher) in the FRONTIER's Prorated Cost to which FRONTIER may be entitled under Section 7.2(b) above. ARTICLE VIII. OPERATIONS ---------- 8.1 Each party shall have full and complete control and responsibility for determining any network and service configuration 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 FRONTIER shall reimburse QWEST for FRONTIER's proportionate share of all operating costs incurred by QWEST in connection with the Regeneration Facilities (or alternatively requested POP or terminal facilities) provided pursuant to Section 7.2(a), 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. FRONTIER'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 FRONTIER in any such facility (including a proportionate share of the common area) bears to (i) in the case of lease costs, the total space in such facility, and (ii) in the case of all other costs (including common area costs), the total utilized space in such facility. QWEST shall submit invoices to FRONTIER on an annual basis for FRONTIER's pro rata share of such operating costs during the preceding twelve months. FRONTIER's reimbursement obligations for insurance and taxes pursuant to this Section 8.2 shall in no event be duplicative of FRONTIER's payment obligations for insurance or taxes, respectively, as provided in Article XIV and XV hereof, and in no event shall relieve QWEST of its payment obligations for insurance costs or taxes, respectively, as provided in Article XIV and XV hereof. 8.3 FRONTIER acknowledges and agrees that, except to the extent expressly provided pursuant to Sections 1.2 and 7.2, QWEST is not supplying nor is QWEST obligated to supply to FRONTIER 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 FRONTIER, nor is QWEST responsible for performing any work other than as specified in this Agreement. 8.4 Upon not less than one hundred twenty (120) days' written notice from QWEST to FRONTIER, QWEST may, subject to FRONTIER's prior written approval (which approval shall not be unreasonably delayed or withheld) substitute for the FRONTIER Fibers on the QWEST System, or any Segment or Segments comprising a portion of said QWEST System, an equal number of alternative fibers along the same or an alternative route; provided that in any such event, such substitution ------------- (i) shall be in accordance with FRONTIER's applicable specifications and operating procedures, (ii) shall be effected at the sole cost of QWEST, including, without limitation, all disconnect and reconnect costs, fees and expenses, (iii) shall be constructed and tested in accordance with the specifications and drawings set forth in Exhibits C and D and Section 4.2, and incorporate fiber meeting the specifications set forth in Exhibit E, and (iv) shall not interrupt or adversely affect the use, operation or performance of FRONTIER's network or business, or change any Connecting Points or endpoints of any Segment or change the location of any Regeneration Facilities (or POPs or terminal facilities) used by FRONTIER hereunder or any other FRONTIER POP, node or switch facilities, all as determined by FRONTIER, in its sole discretion; and provided further that QWEST shall give FRONTIER written notice prior to QWEST's placing any order for fiber for such alternative route segment or segments if the number of fibers to be placed in such alternative route segment or segments exceeds the number of fibers in the Segment or Segments to be so relocated, and FRONTIER shall have a period of thirty (30) days from receipt of such notice to commit, by written notice to QWEST, to acquire an IRU in an additional number of Dark Fibers (i.e., in excess of the number of FRONTIER Fibers to be so substituted) (subject to the availability of adequate conduit capacity) for a per-fiber IRU fee ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## . ARTICLE IX. MAINTENANCE AND REPAIR OF THE QWEST SYSTEM ------------------------------------------ 9.1 From and after the Acceptance Date with respect to each Segment, the maintenance of the QWEST System comprising such Segment shall be provided in accordance with the maintenance requirements and procedures set forth in Exhibit H hereto. ARTICLE X. PERMITS; UNDERLYING RIGHTS; RELOCATION -------------------------------------- 10.1 QWEST covenants and agrees that it shall obtain, during the course of construction of, and in any event on or before the completion of conduit installation with respect to, each Segment of conduit to be delivered hereunder all Underlying Rights (as defined below) and such other rights, licenses, permits, authorizations, and approvals (including, without limitation, any necessary local, state, federal or tribal authorizations and environmental permits) that are necessary in order to permit QWEST to construct, install and maintain the conduit and the FRONTIER Fibers to be encompassed in such Segment in accordance with the terms and conditions hereof. QWEST further covenants and agrees that it shall obtain, during the course of construction of and in any event on or before the Acceptance Date with respect to each Segment to be delivered hereunder, any and all rights-of way, easements, licenses and other agreements relating to the grant of rights and interests in and/or access to the real property underlying the QWEST System (collectively, the "Underlying Rights") and such other rights, licenses, permits, authorizations, and approvals (including without limitation, any necessary local, state, federal or tribal authorizations and environmental permits) that are necessary in order to permit QWEST to grant the IRUs, and otherwise to perform its obligations hereunder, in accordance with the terms and conditions hereof, and to (and all of which Underlying Rights shall) permit FRONTIER to use the FRONTIER Fibers and Associated Property as provided and permitted hereunder and in accordance with the terms and conditions hereof. QWEST shall use its best efforts to cause the terms of each such Underlying Right to provide FRONTIER with notice of any default on the part of QWEST and to permit FRONTIER to cure, on behalf of QWEST, any such default by QWEST and, thereafter, to continue the use of such Underlying Right in accordance with QWEST's rights and interests thereunder and, if FRONTIER at any time cures such default by QWEST, QWEST shall reimburse FRONTIER for any and all amounts reasonably paid by FRONTIER promptly upon demand. 10.2 QWEST further covenants and agrees that, with respect to each Underlying Right that is necessary in order to continue and maintain the IRUs granted hereunder, and to permit FRONTIER to exercise its rights to use the FRONTIER Fibers and Associated Property, in each case in accordance with the terms and conditions hereof: (i) QWEST shall, for a period of ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## years from the date hereof (or until the earlier to occur of (A) the expiration of the economically useful life of the FRONTIER Fibers, as determined pursuant to Section 6.2, or (B) the expiration or termination of the term of a particular Underlying Right, so long as any such termination is not effected as a result of any failure of QWEST (not caused as a result of FRONTIER's failure to observe and perform its obligations hereunder) to observe and perform its duties, obligations and responsibilities under such Underlying Right or under this Agreement, including under this Article X), observe and perform each and every of its obligations under each document, agreement or instrument granting or conveying to QWEST such an Underlying Right if the failure to observe and perform any such obligation or obligations would permit the grantor of such Underlying Right to terminate such Underlying Right prior to its stated expiration date, or would otherwise materially, adversely impair or affect FRONTIER's ability to use the FRONTIER Fibers and Associated Property, or exercise its rights with respect thereto, as provided and permitted hereunder; and (ii) QWEST shall either require that the initial stated term of each such Underlying Right be for a period that does not expire, in accordance with its ordinary terms, prior to the last day of the Minimum Period (as hereinafter defined with respect to each Segment) or, if the initial stated term of any such Underlying Right expires, in accordance with its ordinary terms, on a date earlier than the last day of the Minimum Period, QWEST shall at its cost exercise any renewal rights thereunder, or otherwise acquire such extensions, additions and/or replacements as may be necessary, in order to cause the stated term thereof to be continued until a date that is not earlier than the last day of the Minimum Period. The "Minimum Period" shall be, with respect to each Segment, the period from the date on which construction of such Segment commences until the ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## anniversary of such date; and (iii) From and after the last day of the Minimum Period, QWEST shall use its best efforts (without being required to expend commercially unreasonably amounts therefor) to obtain such extensions and/or renewals as may be necessary in order to cause the stated term of each such Underlying Right to be continued for an additional period or periods of, in the aggregate, ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## years following the Minimum Period or until the earlier expiration of the economically useful life of the FRONTIER Fibers, as determined pursuant to Section 6.2; provided that QWEST shall not be required to expend, as ------------- consideration for any such renewal or extension, more than the fair market rate payable at such time for similar rights and terms except to the extent that FRONTIER agrees at its option to pay directly or reimburse QWEST for any amounts required to be paid in excess of such fair market rate to renew or extend such an Underlying Right; and (iv) Throughout the term of each such Underlying Right, QWEST shall at its reasonable cost and expense defend and protect QWEST's rights in and interests under the Underlying Rights against interfering or infringing rights, interests or claims of third parties. 10.3 Upon the expiration or termination of any Underlying Right that is necessary in order to grant, continue or maintain an IRU granted hereunder in accordance with the terms and conditions hereof, so long as QWEST shall have fully observed and performed its obligations under this Article X with respect thereto, the Term of the IRUs hereunder with respect to any Segment or Segments affected thereby shall automatically expire upon such expiration or termination. 10.4 If, after the Acceptance Date with respect to a Segment, QWEST is required by a third party with legal authority to so require (including, without limitation, the grantor of an Underlying Right, but only to the extent that such relocation is not required as a result of a failure by QWEST to observe and perform its obligations under such Underlying Right or this Agreement), or if FRONTIER agrees, to relocate any portion of such Segment including any of the facilities used or required in providing the IRUs in such Segment hereunder, QWEST shall proceed with such relocation, including, but not limited to, the right, in good faith, to reasonably determine the extent of, the timing of, and methods to be used for such relocation; provided that (i) the route of any such ------------- relocation shall be subject to the good faith agreement of the parties with a bona fide interest therein, (ii) FRONTIER shall be kept fully informed of all other determinations made by QWEST in connection with such relocation, and (iii) any such relocation shall be constructed and tested in accordance with the specifications and drawings set forth in Exhibits C and D, and incorporate fiber meeting the specifications set forth in Exhibit E. FRONTIER shall reimburse QWEST for its proportionate share of the Costs of such relocation of the portion of the Segment so relocated, reduced by such amount, if any, of the portion of such Costs as are reimbursed to QWEST by the party requiring such relocation, as follows: (i) if the affected portion of the Segment includes any conduit other than the conduit housing the FRONTIER Fibers for which QWEST is responsible for relocation costs, the total Costs of relocation of the conduits (i.e., relocation of the conduits only without regard to whether the conduits contain fibers) shall be allocated based on the overall number of conduits relocated; (ii) such Costs allocated to the conduit carrying the FRONTIER Fibers plus the Costs specifically associated with the relocation of the fiber (i.e., relocation of the fiber only without regard to relocation of conduit) shall be further allocated to FRONTIER based on FRONTIER's proportionate share of (A) all Costs of fiber acquisitions, splicing and testing, prorated based on the total fiber count in the affected Cable, as so relocated, and (B) all other Costs associated with the relocation of the conduit housing the affected Cable, prorated based on the total number of owners (including QWEST) and holders of IRUs or equivalent interests (including long-term lessees) (each, an "Interest Holder") in the affected Cable, as so relocated. FRONTIER shall have the right to review and audit all Costs incurred in connection with such relocation. QWEST shall deliver to FRONTIER updated As-Builts with respect to the relocated Segment not later than sixty (60) days following the completion of such relocation. Any condemnation or taking under the power of eminent domain of all or any portion of a Segment shall be deemed a relocation required by a third party with legal authority to so require, and such affected Segment, or portion thereof, shall be relocated in accordance with this Section 10.4 and any condemnation proceeds received by QWEST shall be applied to such relocation as provided above. 10.5 QWEST acknowledges that FRONTIER has previously committed to acquire a certain number of miles of right-of-way from ConRail (the "ConRail ROW"). If determined practical by QWEST in its reasonable business judgment, and provided that the cost and other terms and conditions of acquiring and utilizing part or all of the ConRail ROW are not greater or more restrictive and do not provide lesser rights than any other Underlying Right which QWEST may be hereafter required to acquire in constructing the QWEST System, QWEST shall cooperate with FRONTIER and acquire and utilize the ConRail ROW, or applicable portions thereof, in satisfaction of the FRONTIER commitment to ConRail. In such event, the IRU Fee payable hereunder with respect to any Segment on the ConRail ROW shall be adjusted as agreed by the parties. ARTICLE XI. USE OF QWEST SYSTEM ------------------- 11.1 The requirements, restrictions, and/or limitations upon FRONTIER's right to use the FRONTIER Fibers and Associated Property as provided and permitted under this Agreement imposed under, and associated safety, operational and other rules and regulations imposed in connection with, the Underlying Rights are referred to collectively as the "Underlying Rights Requirements." QWEST represents and warrants that, it has made available to FRONTIER for its review and inspection a copy of certain documents, agreements, or instruments pursuant to which QWEST has been granted an Underlying Right as of the date hereof (the "Existing Underlying Rights"), and certain associated safety, operational and other rules and regulations imposed in connection with the exercise of its rights thereunder (all of which are identified on Exhibit J hereto). FRONTIER hereby accepts the Existing Underlying Rights and the Underlying Rights Requirements associated therewith. QWEST represents that it is not in default under any of the Existing Underlying Rights that would permit the grantor of such Underlying Right to terminate such Underlying Right prior to its stated expiration date, or would otherwise materially, adversely impair or affect FRONTIER's ability to use the FRONTIER Fibers and Associated Property, or exercise its rights with respect thereto, as provided and permitted hereunder, and, to the best of its knowledge, none of the grantors are in default under the Existing Underlying Rights. With respect to each Underlying Right (other than the Existing Underlying Rights) obtained after the date hereof by QWEST (or an Underlying Right existing on the date hereof under any document, agreement or instrument delivered after the date hereof) in carrying out its obligations hereunder from the same type of grantor as a grantor of any Existing Underlying Right, QWEST represents and warrants that the terms and conditions thereof, and rules and regulations imposed in connection therewith, shall not impose materially more onerous limitations and restrictions on the rights of FRONTIER to use the FRONTIER Fibers and Associated Property as permitted and provided hereunder than those imposed by such type of grantor under and in connection with the Existing Underlying Rights and Underlying Rights Requirements associated therewith. To the extent that any such Underlying Right documents, agreements or instruments were or hereafter are provided in a redacted format to protect confidential and proprietary business terms, QWEST represents and warrants that no language or information so redacted constitutes an Underlying Rights Requirement nor otherwise imposes material requirements, restrictions and/or limitations upon FRONTIER's right to use the FRONTIER Fibers and Associated Property as provided and permitted hereunder. QWEST represents to FRONTIER that the map heretofore provided to FRONTIER delineating the general location of rights of way, easements and other rights held by QWEST under the principal agreements evidencing the Existing Underlying Rights is a true and complete depiction, in all material respects, with respect to the general location of such Existing Underlying Rights that relate to the FRONTIER Fibers to be installed along the QWEST System as contemplated by this Agreement. 11.2 FRONTIER represents, warrants and covenants that it will use the FRONTIER Fibers and Associated Property in compliance with (i) all applicable government codes, ordinances, laws, rules, regulations and/or restrictions, and (ii) subject to QWEST's obligations under Section 11.1, the Underlying Rights Requirements. 11.3 In addition to the other rights provided hereunder, but subject to the provisions of Article VII, the IRUs granted hereunder shall include the right at FRONTIER's cost to install additional equipment, or replace existing equipment, in the facility space provided to FRONTIER pursuant to Article VII, subject to the Underlying Rights Requirements. 11.4 QWEST agrees and acknowledges that it has no right to use the FRONTIER Fibers during the Term hereof, and that, from and after the effective date of the grant of each IRU hereunder, QWEST shall keep the FRONTIER Fibers, the Associated Property and the IRUs granted hereunder (other than any Associated Property (excluding any Associated Property that may be covered by the Pre-Existing Cal-Fiber Lien as to which QWEST agrees to use its best efforts to provide a nondisturbance agreement substantially to the effect described in the next sentence) as to which QWEST shall have provided to FRONTIER a nondisturbance agreement substantially to the effect as described in the next sentence) free from (i) any liens of any third party attributable to QWEST, and (ii) any rights or claims of any third party attributable to QWEST, as and to the extent required pursuant to Article X hereof. In addition, QWEST agrees that, from and after the execution of this Agreement and until the effective date of the grant of each IRU hereunder with respect to any Segment, it shall obtain from any entity in favor of which QWEST in its discretion shall have granted a security interest or lien on all or part of such Segment (excluding the Pre-Existing Cal-Fiber Lien) a written nondisturbance agreement substantially to the effect that such lienholder acknowledges FRONTIER's rights and interests in and to the FRONTIER Fibers, the Associated Property and the IRU's hereunder and agrees that the same shall not be diminished, disturbed, impaired or interfered with by such lienholder. 11.5 Subject to the provisions of Article XXV and this Article XI, FRONTIER may use the FRONTIER Fibers, the Associated Property and the IRUs for any lawful telecommunications purpose. For purposes of this Section 11.5 "telecommunications" shall have the meaning as used and interpreted in 47 U.S.C. ' 153(2)(43). FRONTIER agrees and acknowledges that it has no right to use any of the fibers, other than the FRONTIER Fibers, included in the Cable or otherwise incorporated in the QWEST System, and that FRONTIER shall keep any and all of the QWEST System, other than the IRU in the FRONTIER Fibers or in the Associated Property, free from any liens, rights or claims of any third party attributable to FRONTIER. 11.6 FRONTIER and QWEST shall promptly notify each other of any matters pertaining to, or the occurrence (or impending occurrence) of, any event which could give rise to any damage or impending damage to or loss of the QWEST System that are known to such party. Without limiting the generality of the foregoing, QWEST shall promptly forward to FRONTIER a copy of any notice of default received by QWEST with respect to its obligations under any Underlying Right if such default is not promptly cured by QWEST. 11.7 FRONTIER shall not use the FRONTIER 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 QWEST System, it being expressly acknowledged that the QWEST System includes or will include other participants, including QWEST and other owners and holders of Dark Fiber IRUs and telecommunication system operations. QWEST shall not use any other fibers in the QWEST System in a way which physically interferes with or adversely affects the use of the FRONTIER Fibers, and shall obtain a similar agreement from any person that acquires the right to use fibers in the QWEST System after the date hereof. 11.8 FRONTIER 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. 11.9 QWEST agrees, so long as any such action would not violate the terms of any Underlying Right, upon request of FRONTIER, to execute, file and/or record such documents or instruments as FRONTIER shall deem reasonably necessary or appropriate to evidence or safeguard the IRUs granted to FRONTIER hereunder. FRONTIER agrees to reimburse QWEST for all reasonable costs and out-of-pocket expenses (including, without limitation, reasonable fees and expenses of legal counsel) incurred by QWEST in fulfilling its obligations under this Section 11.9. ARTICLE XII. INDEMNIFICATION --------------- 12.1 Subject to the provisions of Articles XIII and XVIII, QWEST hereby releases and agrees to indemnify, defend, protect and hold harmless FRONTIER and its employees, officers and directors, from and against, and assumes liability for: (a) Any injury, loss or damage to any person (including FRONTIER), tangible 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, licensees, invitees or vendors arising out of or in connection with a default (other than a default caused by a failure of FRONTIER to perform or comply with its obligations hereunder) by QWEST in the performance of its obligations or breach of its representations under this Agreement (including, without limitation, any default by QWEST in the performance of its obligations under Article X with respect to the Underlying Rights and under Article XI with respect to its use of the QWEST System); and (b) Any claims, liabilities or damages, including reasonable attorneys' fees and costs, arising out of any violation by QWEST of any regulation, rule, statute 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 XIII and XVIII, FRONTIER hereby releases and 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 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 FRONTIER, 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 FRONTIER in the performance of its obligations or breach of its representations under this Agreement (including, without limitation, any default by FRONTIER in the performance of its obligations under Article XI with respect to its use of the QWEST System); and (b) Any claims, liabilities or damages, including reasonable attorneys' fees and costs, arising out of any violation by FRONTIER of any regulation, rule, statute or court order of any local, state or federal governmental agency, court or body in connection with its use of the IRUs and/or the FRONTIER Fibers and Associated Property hereunder. 12.3 The parties agree to promptly provide each other with notice of any lawsuit, judicial, administrative or other dispute resolution action or proceeding, or claim of which it becomes aware and which it believes may result in an indemnification obligation hereunder (each, an "Action"); provided that ------------- the failure to provide any such notice shall not affect the indemnifying party's indemnification obligation unless the indemnifying party is actually prejudiced by the failure to receive such notice. After receipt of any such notice, if the indemnifying party shall acknowledge in writing to the indemnified party that the indemnifying party shall be obligated under the terms of this indemnity hereunder in connection with such Action, then the indemnifying party shall be entitled, if it so elects (i) to take control of the defense and investigation of such Action, (ii) to employ and engage attorneys of its own choice to handle and defend the same, at the indemnifying party's cost, risk and expense unless the named parties to such action or proceeding include both the indemnifying party and the indemnified party and the indemnified party has been advised in writing by counsel that there may be one or more legal defenses available to such indemnified party that are different from or additional to those available to the indemnifying party, in which case the indemnified party shall also have the right to employ its own counsel in any such case with the reasonable fees and expenses of such counsel being borne by the indemnifying party, and (iii) to compromise or settle such Action, which compromise or settlement shall be made only with the written consent of the indemnified party, such consent not to be unreasonably withheld. Notwithstanding anything in this Section 12.3 to the contrary, (i) if there is a reasonable probability that an indemnifiable claim may materially adversely affect the indemnified party, other than as a result of money damages or other money payments, the indemnified party shall have the right to participate in such defense, compromise or settlement and the indemnifying party shall not, without the indemnified party's written consent (which consent shall not be unreasonably withheld), settle or compromise any indemnifiable claim or consent to entry of any judgment in respect thereof unless such settlement, compromise or consent includes as an unconditional term thereof the giving by the claimant or the plaintiff to the indemnified party a release from all liability in respect of such indemnifiable claim. 12.4 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 the right to bring legal proceedings against the other party for its damages as a result of the other party's said failure to indemnify, defend, protect and save harmless. The obligations of the parties under this Article XII shall survive the expiration or termination of this Agreement. 12.5 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 construction, operation or use of the FRONTIER Fibers or the QWEST System; 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. ARTICLE XIII. LIMITATION OF LIABILITY ----------------------- 13.1 Notwithstanding any provision of this Agreement to the contrary, except to the extent caused by its own willful misconduct, 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, loss of profits or revenue (whether arising out of transmission interruptions or problems, any interruption or degradation of service or otherwise), cost of capital, or claims of customers, in each case whether occasioned by any construction, reconstruction, relocation, repair or maintenance performed by, or failed to be performed by, the other party or any other cause whatsoever, including breach of contract, breach of warranty, negligence, or strict liability, all claims with respect to which such special, incidental, indirect, punitive or consequential damages are hereby specifically waived. Nothing contained herein shall be construed to prohibit or reduce the payment by QWEST of the amounts described in Section 18.2 and which the parties acknowledge are the sole rights and remedies of FRONTIER to the extent provided in Section 18.2(e). ARTICLE XIV. INSURANCE --------- 14.1 During the construction period with respect to any Segment, and until the Acceptance Date with respect thereto, QWEST shall procure and maintain in force the following insurance coverage from companies lawfully approved to do business in the state where the construction will be performed: (a) not less than $5,000,000 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 $1,000,000 per occurrence; (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 $2,000,000 per occurrence; and (d) any other insurance coverages required pursuant to QWEST's right-of-way agreements with railroads or other third parties. QWEST shall require its subcontractors who are engaged in connection with the construction of the QWEST System to maintain insurance in the types and amounts as would be obtained by a prudent person to provide adequate protection against loss. In all circumstances, QWEST shall require its subcontractors to carry a minimum of $1,000,000 in commercial general liability; and (e) FRONTIER shall be listed as an additional insured on all policies set forth above, except workers' compensation. QWEST shall provide to FRONTIER a certificate of insurance evidencing such insurance coverage. Evidence of insurance furnished shall contain a clause stating FRONTIER "shall be notified in writing at least thirty (30) days prior to any cancellation of, or any material change or new exclusions in the policy." 14.2 Following the Acceptance Date with respect to each Segment, and throughout the remaining term of the IRU with respect to such Segment, each party shall procure and maintain in force, at its own expense: (a) not less than $5,000,000 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 $1,000,000 per occurrence; (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 $2,000,000 per occurrence; and (d) any other insurance coverages specifically required of such party pursuant to QWEST's right-of-way agreements with railroads or other third parties. 14.3 Both parties expressly acknowledge that a party shall be deemed to be in compliance with the provisions of this Article if it maintains an approved self insurance program providing for a retention of up to $1,000,000. If either party 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, FRONTIER'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. 14.4 In the event either party fails to obtain the required insurance or to obtain the required certificates from any contractor 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. 14.5 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. 14.6 FRONTIER and QWEST shall each obtain from the insurance companies providing the coverages required by this Agreement the permission of such insurers to allow such party to waive all rights of subrogation and such party does hereby waive all rights of said insurance companies to subrogation against the other party, its parent corporation, affiliates, subsidiaries, assignees, officers, directors, and employees or any other party entitled to indemnity under this Agreement. ARTICLE XV. TAXES, FEES AND OTHER GOVERNMENTAL IMPOSITIONS ---------------------------------------------- 15.1 The parties acknowledge and agree that it is their mutual objective and intent to (i) minimize, to the extent feasible, the aggregate Impositions (as defined in Section 33.1(e)) payable with respect to the QWEST System and (ii) share such Impositions according to their respective interests in the QWEST System , 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 XV. 15.2 QWEST shall be responsible for and shall timely pay any and all Impositions with respect to the construction or operation of the QWEST System which Impositions are (i) imposed or assessed prior to the Acceptance Date, (ii) imposed or assessed with respect to events which occurred or property rights or obligations of QWEST which existed prior to the acceptance date; or (iii) imposed or assessed (regardless of the time) with respect to the QWEST System in exchange for the approval of construction in the original agreement which resulted in the granting of an Underlying Right. Notwithstanding the foregoing obligations, QWEST shall have the right to challenge any such Impositions so long as the challenge of such Impositions does not materially, adversely affect the title, rights or property to be delivered to FRONTIER pursuant hereto. 15.3 Except as to Impositions described in paragraphs (ii) and (iii) of Section 15.2, following the Acceptance Date, QWEST shall timely pay any and all Impositions imposed upon or with respect to the QWEST System to the extent such Impositions may not feasibly be separately assessed or imposed upon or against the respective ownership interests of QWEST and FRONTIER in the QWEST System; provided that, upon receipt of a notice of any such Imposition, QWEST shall promptly notify FRONTIER of such Imposition and following payment of such Imposition by QWEST, FRONTIER shall promptly reimburse QWEST for its proportionate share of such Imposition, which share shall be determined (i) to the extent possible, based upon the manner and methodology used by the particular authority imposing such Impositions (e.g., on the cost of the relative property interests, historic or projected revenue derived therefrom, or any combination thereof) and, if based upon projected revenue or gross receipts, then based on the relative number of FRONTIER Fibers in the affected portion of the QWEST System compared to the total number of fibers in the affected portion of the QWEST System during the relevant tax period which are subject to an indefeasible right of use or are otherwise in use; or (ii) if the same cannot be so determined, then based upon FRONTIER's proportionate share of the total fiber count in the affected portion of the QWEST System. QWEST shall provide FRONTIER with reasonable supporting documentation for Impositions for which QWEST seeks reimbursement. If QWEST's assessed value, for property tax purposes, is based on its entire operation in any state (i.e., central assessment), QWEST and FRONTIER shall work together in good faith to allocate a proper portion of said assessment to the QWEST System and FRONTIER's ownership interest in the QWEST System. Any reimbursement made under this Section 15.3 shall be in an amount equal to the Impositions required to be paid by QWEST in respect of the receipt or accrual of such reimbursement less the net present value (computed at a 10% discount rate) of the tax benefit (e.g. from the deduction, depreciation or amortization of such payment or accrual of the Imposition) to which QWEST may be entitled with respect to the payment or accrual of the Impositions which have been reimbursed. Hereafter, such additional amount or amounts shall be referred to as the "Gross-up Amount." Such Gross-up Amount shall not include any tax on the amount of the Gross-up Amount itself. QWEST shall, upon request, provide FRONTIER with documentation in support of any Gross-up Amount so as to ensure that both parties are made whole in a manner that is consistent with the mutual objectives set forth in section 15.1 of the Agreement. If such Gross-up Amount exceeds $50,000, FRONTIER may elect to engage the services of an independent consultant, at FRONTIER's sole cost and expense, to review QWEST's computation of such Gross-up Amount. Any independent consultant selected by FRONTIER shall be subject to approval by QWEST, which such approval shall not be unreasonably withheld, and such independent consultant shall be subject to confidentiality restrictions as may be determined in QWEST's sole discretion. Further, if, after review of such documentation or otherwise, in the event the parties are unable to agree upon the amount of the Gross-up Amount, such dispute shall be resolved pursuant to Article XXI of the Agreement. 15.4 Upon notice of the assertion or proposed assertion of any imposition described in Section 15.3 (including Impositions that trigger a Gross-up Amount) QWEST shall promptly and in good faith consult with FRONTIER concerning the underlying facts and whether to contest or continue to contest such assertion or proposed assertion. Notwithstanding any provision herein to the contrary, QWEST shall have the right to contest any Imposition described in Section 15.3, above, (including Impositions which trigger a Gross-up Amount). Such contest may be pursued by any lawful means including by non-payment of such Imposition provided such non-payment does not materially, adversely affect the title, rights or property to be delivered to FRONTIER pursuant hereto). The out-of-pocket costs and expenses (including reasonable attorneys' fees) incurred by QWEST in any such contest shall be shared by QWEST and FRONTIER in the same proportion as to which the parties shared in any such Imposition, as it was originally assessed. Any refunds or credits resulting from a contest brought pursuant to this Section 15.4 shall be divided between QWEST and FRONTIER in the same proportion as to which such refunded or credited Impositions were borne by QWEST and FRONTIER. In any such event, QWEST shall provide timely notice of such challenge to FRONTIER. If QWEST chooses to proceed with such challenge after receipt of a written objection to the challenge from FRONTIER, QWEST shall conduct such challenge at its own costs and expense, provided that FRONTIER shall not receive the benefit of any refund or credit, if any, obtained as a result of a successful challenge. Further, where QWEST does not contest an Imposition, FRONTIER shall have the right, after notice to QWEST, to contest such Imposition as long as such contest does not materially, adversely affect the title property or rights of QWEST. The out-of-pocket costs and expenses (including reasonable attorney's fees) incurred by FRONTIER in any such contest shall be shared by FRONTIER and QWEST in the same proportion as to which the parties shared in such Imposition, as it was originally assessed. Any refunds or credits resulting from a contest shall be divided between FRONTIER and QWEST in the same proportion as to which such refunded or credited Imposition was borne by FRONTIER and QWEST. If FRONTIER chooses to proceed with such contest after receipt of written objection to the challenge from QWEST, FRONTIER shall conduct such challenge at its own costs and expense, provided that QWEST shall not receive the benefit of any refund or credit, if any, obtained as a result of a successful challenge. Provided, however, that notwithstanding anything to the contrary in this Article 15, QWEST shall have complete authority over and discretion to control (including the authority to dismiss or not pursue) any contests relating to Impositions based upon the computation of QWEST's taxable income under the Federal Internal Revenue Code or state income or franchise tax laws (hereinafter "Net Income Based Impositions"). FRONTIER shall, however, be consulted on the conduct and status of such contest. QWEST shall have no obligation to disclose to FRONTIER its income or franchise tax returns and records except as to the discrete portion of such return or record that directly relates to the computation and payment of such Net Income Based Impositions. Provided further, however, that in the event QWEST shall determine in its own discretion not to pursue a contest of any Net Income Based Imposition as to which FRONTIER has requested a contest pursuant to the provisions described above in this Section 15.4, then FRONTIER shall have no obligation to provide any reimbursement for such amount if FRONTIER shall have obtained and provided to QWEST an opinion of nationally recognized legal counsel confirming that a meritorious defense exists to such Net Income Based Imposition. 15.5 Except as to Impositions described in paragraph (iii) of Section 15.2, following the Acceptance Date QWEST and FRONTIER, respectively, shall be separately responsible for any and all Impositions (i) expressly or implicitly imposed upon, based upon, or otherwise measured by the gross receipts, gross income, net receipts or net income received by or accrued to such party due to its respective ownership or use of the QWEST System and/or the FRONTIER Fibers, or (ii) which have been separately assessed or imposed upon the respective ownership interest of such party in the QWEST System and/or the FRONTIER Fibers. If the FRONTIER Fibers are the only fibers located in the Cable from the point where the Cable leaves the QWEST System right-of-way to a FRONTIER POP, FRONTIER shall be solely responsible for any and all Impositions imposed on or with respect to such portion of the QWEST System. 15.6 Notwithstanding any provision herein to the contrary, FRONTIER shall have the right to protest by appropriate proceedings any Imposition described in Section 15.5, above. In such event, FRONTIER shall indemnify and hold QWEST harmless from any expense, legal action or cost, including reasonable attorneys' fees, resulting from FRONTIER's exercise of its rights hereunder. In the event of any refund, rebate, reduction or abatement to FRONTIER of any such Imposition imposed upon and/or paid by FRONTIER, FRONTIER shall be entitled to receive the entire benefit of such refund, rebate, reduction or abatement attributable to FRONTIER's use of the QWEST System. In the event FRONTIER has exhausted all its rights of appeal in protesting any Imposition and has failed to obtain the relief sought in such proceedings or appeals ("Finally Determined Taxes and Fees"), FRONTIER and QWEST may jointly agree (with the consent and participation of the other Interest Holders in the affected portion of the QWEST System) to relocate a portion of the QWEST System so as to bypass the jurisdiction which had imposed or assessed such Finally Determined Taxes and Fees with the total Costs thereof to be shared proportionately as follows: (i) if the affected portion of the QWEST System includes any conduit other than the conduit in which the FRONTIER Fibers are located, the total Costs of relocation of the conduits (i.e., relocation of the conduits only without regard to whether the conduits contain fibers) shall be allocated based on the overall number of conduits in the QWEST System which are relocated; and (ii) such Costs allocated to the conduit carrying the FRONTIER Fibers plus the Costs specifically associated with the relocation of the fiber (i.e., relocation of the fiber only without regard to relocation of conduit) to be further allocated to FRONTIER based upon FRONTIER's proportionate share of (A) all Costs of fiber acquisitions, splicing and testing, prorated based on the total fiber count in the Cable, as so relocated; and (B) all other Costs associated with the relocation of the conduit housing the affected Cable, prorated based upon the total number of Interest Holders in the affected Cable, as so relocated. QWEST shall deliver to FRONTIER updated As-Builts with respect to the relocated QWEST System not later than sixty (60) days following the completion of such relocation. If FRONTIER and QWEST do not determine to relocate the affected portion of the QWEST System, FRONTIER shall have the right to terminate its use of the FRONTIER Fibers in the affected portion of the QWEST System. Such termination shall be effective on the date specified by FRONTIER in a notice of termination, which date shall be at least ninety (90) days after the notice. Upon such termination, the IRU in the affected portion of the QWEST System shall immediately terminate, and the FRONTIER Fibers in the affected portion of the QWEST System shall thereupon revert to QWEST without reimbursement of any of the IRU Fee or other payments previously made with respect thereto. 15.7 Notwithstanding the provisions of Section 15.6, with respect to any Impositions relating to the QWEST System which are imposed upon both QWEST and FRONTIER (or both of their respective interests therein), QWEST, at its option and at its own expense, shall have the right to direct and manage any such contest; subject, however, to reasonable and appropriate consultation with FRONTIER which hereby agrees to cooperate with QWEST in any such contest. The right of QWEST to contest any Imposition pursuant to this Section 15.7 shall be contingent upon reasonable and appropriate assurances that any such contest will not adversely affect the title, property or rights of FRONTIER hereunder. 15.8 QWEST and FRONTIER agree to cooperate fully in the preparation of any returns or reports relating to the Impositions. QWEST and FRONTIER further acknowledge and agree that the provisions of this Article XV are intended to allocate the Impositions expected to be assessed against or imposed upon the parties with respect to the QWEST System based upon the procedures and methods of computation by which Impositions generally have been assessed and imposed to date, and that material changes in the procedures and methods of computation by which such assessments are assessed and imposed could significantly alter the fundamental economic assumptions underlying the transactions hereunder to the parties. Accordingly, the parties agree that, if in the future the procedures or methods of computation by which Impositions are assessed or imposed against the parties change materially from the procedures or methods of computation by which they are imposed as of the date hereof, the parties will negotiate in good faith an amendment to the provisions of this Article XV in order to preserve, to the extent reasonably possible, the economic intent and effect of this Article XV as of the date hereof.

CONFIDENTIALITY --------------- 17.1 QWEST and FRONTIER 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. The parties acknowledge and agree that this Agreement, including all of the terms, conditions and provisions hereof, and all drafts hereof, constitutes Proprietary Information. In addition, all information disclosed by either party to the other in connection with or pursuant to this Agreement, including prior to the date hereof, shall be deemed to be Proprietary Information. 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, 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 any Proprietary Information which (i) becomes publicly available other than through the recipient; (ii) is required to be disclosed by a governmental or judicial law, order, rule or regulation; (iii) is independently developed by the disclosing party; (iv) becomes available to the disclosing party without restriction from a third party; or (v) becomes relevant to 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 (ii), the party required to make such disclosure shall promptly inform the other party of the requirements of such disclosure. 17.3 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. In addition, notwithstanding Sections 17.1 and 17.2 of this Article, FRONTIER may disclose this Agreement and its terms, conditions and provisions to the Permitted System Acquiror and/or the Permitted Sacramento/Seattle Acquiror (each as defined in Section 25.3(b)), provided that (i) such Permitted System Acquiror and/or Permitted - ------------- Sacramento/Seattle Acquiror, prior to any such disclosure, shall have been notified of the confidential and proprietary nature of this Agreement and its terms, conditions and provisions and shall have entered into a written confidentiality agreement with substantially similar (and in no event less restrictive than the) terms of the Confidentiality Agreement between QWEST and FRONTIER dated February 15, 1995, (ii) copies of all or any portion of this Agreement (including Exhibits) may not be furnished to the Permitted System Acquiror and/or the Permitted Sacramento/Seattle Acquiror without the prior written consent of QWEST (not unreasonably withheld or delayed) of the proposed form of disclosure thereof (redacted or otherwise), and (iii) copies of all or any portion of any Underlying Right may not be furnished without the prior written consent of QWEST (not unreasonably withheld or delayed). 17.4 The provisions of this Article XVII shall survive expiration or termination of this Agreement. ARTICLE XVIII. DEFAULT ------- 18.1 With respect to all payments required to be made by FRONTIER hereunder, including, without limitation, payment of the IRU Fee and all other amounts payable by FRONTIER hereunder, in the event FRONTIER shall fail to make a payment by the date due and payable hereunder, from and after such date, (i) such unpaid amount shall bear interest until paid at a rate equal to the rate set forth in Article XXX and (ii) if such payment is due with respect to a Segment on or prior to the Acceptance Date of such Segment, the Estimated Delivery Date for such 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 eighty (80) days after written notice from QWEST to FRONTIER, and the amount thereof is not in bona fide dispute, then QWEST may, in its sole and absolute discretion and in addition to its other rights and remedies hereunder, after ten (10) days prior written notice to FRONTIER and the failure of FRONTIER to pay such amount within such ten-day period, terminate any and all of its obligations hereunder with respect to any Segment or Segments as to which the Acceptance Date has not yet occurred or the grant of the IRU with respect to which has not yet become effective, and to apply any and all amounts previously paid by FRONTIER hereunder with respect to such Segment or Segments toward the payment of any other amounts then or thereafter payable by FRONTIER hereunder. With respect to all of its other obligations hereunder, in the event FRONTIER shall fail to perform a non-payment obligation and such failure shall continue for a period of thirty (30) days after QWEST shall have given FRONTIER written notice of such failure, FRONTIER shall be in default hereunder unless FRONTIER 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 FRONTIER 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 ---------------- FRONTIER certifies in good faith to QWEST in writing that a non-payment failure has been cured, such failure shall be deemed to be cured unless QWEST otherwise notifies FRONTIER in writing within fifteen (15) days of receipt of such notice from FRONTIER. FRONTIER shall be in default hereunder (i) automatically upon the making by FRONTIER or Frontier Corporation of a general assignment for the benefit of its creditors, the filing by FRONTIER or Frontier Corporation of a voluntary petition in bankruptcy or the filing by FRONTIER or Frontier Corporation of any petition or answer seeking, consenting to, or acquiescing in reorganization, arrangement, adjustment, composition, liquidation, dissolution, or similar relief; (ii) one hundred twenty (120) days after the filing of an involuntary petition in bankruptcy or other insolvency protection against FRONTIER or Frontier Corporation which is not dismissed within such one hundred twenty (120) days, or (iii) upon any default by Frontier Corporation under the Guaranty, which default is not cured within the relevant cure period, if any, provided with respect thereto under the Guaranty. Except as otherwise provided in this Section 18.1, upon any default by FRONTIER, after written notice thereof from QWEST, QWEST may (i) 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 FRONTIER its reasonable costs incurred in correcting such default, and (ii) pursue any legal remedies it may have under applicable law or principles of equity relating to such default, including specific performance. Notwithstanding any other provision of this Agreement, QWEST acknowledges and agrees that QWEST shall have no right to terminate the IRU or any of the rights and interests of FRONTIER hereunder with respect to any Segment for which the IRU Fee relating thereto has been fully paid. 18.2 (a) With respect to its obligation to complete the construction, installation, and satisfactory Fiber Acceptance Testing of the FRONTIER Fibers comprising a particular Segment by the Estimated Delivery Date with respect to such Segment pursuant to Section 3.2, the parties acknowledge and agree that it is in their mutual best interest to work together in a cooperative effort to determine whether and to what extent any event or occurrence that is reasonably likely to cause a delay in the delivery of a Segment hereunder, as a result of any force majeure event or other occurrence described in Article XX or otherwise, can be terminated, resolved or avoided, and to cause the construction, installation and delivery of the Segment to be completed in the most expeditious and practical manner feasible under the circumstances. Accordingly, within three (3) months following its discovery of an event or occurrence that QWEST reasonably believes is likely to cause (i) an extension of the Estimated Delivery Date of one hundred twenty (120) days or more pursuant to Article XX or (ii) a Delivery Default (as defined pursuant to Section 18.2(d) below), QWEST shall give written notice to FRONTIER of such event or occurrence. Thereupon, each of QWEST and FRONTIER (i) will designate a senior executive officer with decision-making authority and familiarity with this Agreement and the relevant issue hereunder, and (ii) may designate one technical representative and one financial representative, to participate in the following resolution efforts. Each of such designees shall participate in such meetings, promptly scheduled at mutually agreed upon times and places, as may be necessary or appropriate to discuss in good faith the status of construction of the affected Segment, the reason or reasons for the anticipated Estimated Delivery Date extension or Delivery Default, various possible and practical means by which the event(s) or occurrence(s) causing such anticipated Estimated Delivery Date extension or Delivery Default might be terminated, avoided or resolved, including, without limitation, possible modifications to the route, selection of right-of-way, or manner of construction of the affected Segment, and (iii) use their best efforts to settle upon and implement a procedure by which such event(s) or occurrence(s) may be terminated, avoided or resolved and the construction, installation and delivery of the affected Segment completed in an expeditious and economically practical and feasible manner under the circumstances. The parties acknowledge and agree that, because the QWEST System includes or will include other participants, including owners and holders of Dark Fiber IRUs and telecommunication system operations, such meetings may, and likely will, involve designees and representatives of such other participants, and the resolution of any matters so acted upon will require the cooperative efforts of, and have to be structured, to the extent feasible, in an effort to meet the needs of all such participants. The parties hereto further acknowledge and agree that no failure of the parties hereto to resolve, or to agree upon a manner in which they might resolve, any issue addressed hereunder shall impair, adversely affect or invalidate any of their respective rights, claims or remedies under this Agreement. (b) If, notwithstanding the efforts of the parties pursuant to Section 18.2(a): (i) (A) a force majeure event or occurrence described in Article XX causing an anticipated Estimated Delivery Date extension has not been terminated, avoided or resolved by the date that is twelve (12) months following QWEST's discovery of such event or occurrence, and (B) there is no "Reasonably Apparent Probability" (either as mutually determined by QWEST and FRONTIER or, if QWEST and FRONTIER are unable to make such a mutual determination, as determined by an independent third party mutually selected by QWEST and FRONTIER and familiar with large-scale fiberoptic system constructions projects or, if QWEST and FRONTIER are unable to make such a mutual selection, each of QWEST and FRONTIER shall designate such an independent third party, the two of which shall designate such an independent third party to make such determination) that the Acceptance Date with respect to any such affected Segment will occur within (1) twelve (12) months following the Estimated Delivery Date (without extension for any delay pursuant to Article XX) with respect to any Segment designated as a "priority" Segment on Exhibit A-1, or (2) eighteen (18) months following the Estimated Delivery Date (without extension for any delay pursuant to Article XX) with respect to any other Segment (such date with respect to each Segment being referred to as the "Outside Force Majeure Date"); or (ii) notwithstanding a determination pursuant to the foregoing clause (i) that there was a Reasonably Apparent Probability that the Acceptance Date with respect to the affected Segment would occur by the applicable Outside Force Majeure Date, nonetheless the event or occurrence described in Article XX causing such delay is continuing on such applicable Outside Force Majeure Date; or (iii) notwithstanding such a determination that there was a Reasonably Apparent Probability that the Acceptance Date with respect to the affected Segment would occur by the applicable Outside Force Majeure Date, nonetheless, on the applicable Outside Force Majeure Date, although the event or occurrence described in Article XX has been terminated, avoided or resolved and QWEST has resumed its construction, installation, splicing, and/or testing efforts, QWEST is unable to demonstrate to FRONTIER's reasonable satisfaction that the Acceptance Date for such Segment will occur, in all reasonable probability, by the date that is six (6) months following such Outside Force Majeure Date, then, in any such event described in foregoing clauses (i), (ii), and (iii), FRONTIER may elect, in its sole discretion, by written notice to QWEST, to delete such Segment from the System Route otherwise to be delivered pursuant to this Agreement, and recover from QWEST (1) the amount of the IRU Fee previously paid by FRONTIER hereunder with respect to such Segment, plus (2) interest at the prime rate interest published by The Wall Street Journal as the base rate on ----------------------- corporate loans posted by a substantial percentage of the nation's largest banks on such date, plus (3) an amount equal to ten percent (10%) of the IRU Fee for such Segment, as determined or redetermined pursuant to Section 2.1 (with such aggregate amount payable to FRONTIER promptly following QWEST's receipt of such election notice or, at the election of FRONTIER, offset against the unpaid amount of the IRU Fee payable hereunder with respect to any other Segment or Segments). Upon any such election and payment (or offset), neither party shall have any further rights or obligations with respect to such Segment hereunder. (c) If, notwithstanding the efforts of the parties pursuant to Section 18.2(a): (i) (A) an event or occurrence causing an anticipated Delivery Default (as defined in Section 18.2(d) below) has not been terminated, avoided, resolved or waived by the date that is twelve (12) months following QWEST's discovery of such event or occurrence; and (B) there is no Reasonably Apparent Probability that the Acceptance Date with respect to any such affected Segment will occur within (x) twelve (12) months following the Estimated Delivery Date with respect to each Segment designated as a "priority" Segment on Exhibit A-1, or (y) eighteen (18) months following the Estimated Delivery Date with respect to any other Segment (such dates being referred to collectively as the "Outside Delivery Default Date"); or (ii) notwithstanding a determination pursuant to the foregoing clause (i) that there was a Reasonably Apparent Probability that the Acceptance Date with respect to the affected Segment would occur by the applicable Outside Delivery Default Date, nonetheless, on the applicable Outside Delivery Default Date, the Acceptance Date for such Segment has not occurred; then, in any such event described in the foregoing clauses (i) and (ii), FRONTIER may elect, in its sole discretion, by written notice to QWEST, to delete such Segment from the System Route otherwise to be delivered pursuant to this Agreement, and recover from QWEST (1) the amount of the IRU Fee previously paid by FRONTIER hereunder with respect to such Segment, plus (2) interest thereon at the rate of interest applicable to late payments set forth in Article XXX, plus (3) an amount equal to ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## ) of the IRU Fee for such Segment, as determined or redetermined pursuant to Section 2.1, but without reduction of such IRU fee under Section 18.2(d) (with such aggregate amount payable to FRONTIER promptly following QWEST's receipt of such election notice or, at the election of FRONTIER, offset against the unpaid amount of the IRU Fee payable hereunder with respect to any other Segment or Segments). Upon any such election and payment (or offset), neither party shall have any further rights or obligations with respect to such Segment hereunder. (d) In addition to the specific rights and remedies provided pursuant to the foregoing paragraphs (b) and (c) in connection with delays and anticipated delays in the delivery of Segments hereunder, QWEST shall be in default under this Agreement if the Acceptance Date with respect to any Segment has not occurred within one hundred twenty (120) days after the Estimated Delivery Date (a "Delivery Default"). From the date of any such Delivery Default, and until the Acceptance Date with respect to such Segment occurs, the IRU Fee with respect to such Segment, as determined or redetermined pursuant to Section 2.1 hereof, shall be reduced by an amount equal to ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## % of such IRU Fee for each thirty (30) days (or a pro rata percentage of ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## % for any period of less than thirty (30) days) that elapse between such date of Delivery Default and the Acceptance Date. (e) The rights and remedies set forth in the foregoing Sections 18.2(c) and 18.2(d) shall be the sole remedies available to FRONTIER with respect to any failure by QWEST to construct, install, and conduct satisfactory Fiber Acceptance Testing with respect to the FRONTIER Fibers comprising any Segment by the relevant Estimated Delivery Date (it being expressly acknowledged and agreed that the rights provided to FRONTIER pursuant to Section 18.2(b) are provided only as an accommodation in the event of lengthy force majeure delays pursuant to Article XX, and that the events described in Section 18.2(b) do not constitute defaults hereunder). With respect to all of QWEST's other 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 FRONTIER 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 FRONTIER within such thirty (30) days; provided however, that where such failure cannot reasonably be cured ---------------- within such 30-day period, if QWEST 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 QWEST certifies in good faith to FRONTIER in ---------------- writing that failure has been cured, such failure shall be deemed to be cured unless FRONTIER otherwise notifies QWEST in writing within fifteen (15) days of receipt of such notice from QWEST. QWEST shall be in default hereunder 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 (ii) 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 18.2, upon any default by QWEST, after notice thereof from FRONTIER, FRONTIER may (i) 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 QWEST its reasonable costs in correcting such default, and (ii) pursue any legal remedies it may have under applicable law or principles of equity relating to such default including specific performance. ARTICLE XIX. 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 such Segment pursuant to Article VI or Section 18.2 hereof. 19.2 Upon the expiration or termination of this Agreement with respect to a Segment, the IRU in such Segment shall immediately terminate and all rights of FRONTIER to use the QWEST System, the FRONTIER Fibers, the Associated Property or any part thereof relating to such Segment, shall cease and QWEST shall owe FRONTIER no additional duties or consideration with respect to such Segment. Promptly thereupon, FRONTIER shall remove all of FRONTIER's electronics, equipment, separate Regeneration Facilities (as provided pursuant to Section 7.2) and other associated FRONTIER property from such Segment and any related QWEST facilities at its sole cost under QWEST's supervision (which supervision shall be without cost to FRONTIER). 19.3 Notwithstanding the foregoing, no termination or expiration of this Agreement shall affect the rights or obligations of any party hereto (i) 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 or (ii) pursuant to Article XII, Article XIII, Article XV or Article XVII herein, which shall survive the expiration or termination hereof. ARTICLE XX. 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 delivery 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 QWEST System and that will include the FRONTIER Fibers must include higher fiber counts than that necessary solely for the FRONTIER Fibers in order to permit completion of the entire QWEST System); lack of or delay in transportation; government codes, ordinances, laws, rules, regulations or restrictions (collectively, "Regulations"); war or civil disorder; strikes or other labor disputes; failure of a third party to grant or recognize an Underlying Right, or any other cause beyond the reasonable control of such party; provided that any delay caused by the failure of a third party to ------------- grant an Underlying Right shall constitute a force majeure delay hereunder only to the extent that such delay does not extend beyond a period of six months (such that the Estimated Delivery Date with respect to any Segment affected by such delay shall be extended only up to a period of six months of any such delay, and shall not be further extended if such delay extends beyond a period of six months). 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. ARTICLE XXI 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 as follows: (a) Officers. Either party may refer the matter to the Chief Executive -------- Officers or the Chief Operating Officers (the "Officers") of the parties by giving the other party written notice (a "Notice"). Within fifteen (15) days after delivery of a Notice, the Officers of both parties shall meet at a mutually acceptable time and place to exchange relevant information and to attempt to resolve the dispute. (b) Negotiation. If the matter has not been resolved within thirty (30) ----------- days after delivery of such Notice, or if the Officers fail to meet within fifteen (15) days after delivery of such Notice, either party may initiate mediation and, if applicable, arbitration in accordance with the procedure set forth in subsections (c) and (d) below. All negotiations conducted by the Officers pursuant to this clause are confidential and shall be treated as compromise and settlement negotiations for purposes of the Federal Rules of Evidence and State Rules of Evidence. (c) Mediation. In the event a dispute exists between the parties and the --------- respective Officers are unable to resolve the dispute, the parties agree to participate in a non-binding mediation procedure as follows: (i) A mediator will be selected by having counsel for each party agree on a single person to act as mediator. The parties' counsel as well as the Officers of each party and not more than two other participants from each party will appear before the mediator at a time and place determined by the mediator, but not more than sixty (60) days after delivery of a Notice. The fees of the mediator and other costs of mediation will be shared equally by the parties. (ii) Each party's counsel will have forty-five (45) minutes to present a review of the issue and argument before the mediator. After each counsel's presentation, the other counsel may present specific counter-arguments not to exceed ten (10) minutes. The 45-minute and 10-minute periods will be exclusive of the time required to answer questions from the mediator or attendees. (iii) After both presentations, the Officers may ask questions of the other side. At the conclusion of both presentations and the question periods, the Officers and their counsels will meet together to attempt to resolve the dispute. The length of the meeting will be as agreed between the parties. Either party may abandon the procedure at the end of the presentations and question periods if they feel it is not productive to go further. The mediation procedure is not binding on either party. (iv) The duties of the mediator are to be sure that the above set-out time periods are adhered to and to ask questions so as to clarify the issues and understandings of the parties. The mediator may also offer possible resolutions of the issues but has no duty to do so. (d) Arbitration. If the matter is not resolved after applying the ----------- mediation procedures set forth above, or if either party refuses to take part in the mediation process, the parties hereby agree to submit all controversies, claims and matters of difference that are unresolved to arbitration in Chicago, Illinois, according to the commercial rules and practices of the American Arbitration Association ("AAA") from time to time in force, and in accordance with the following provisions of this subsection (d), and unless otherwise agreed by the parties and subject to the rights of the parties as provided in Section 18.1 and Section 18.2 hereof (including the right not to continue to perform under this Agreement), they shall continue to perform under this Agreement during arbitration.

(ii) Arbitration hereunder shall be by three independent and impartial arbitrators. Each of the parties shall appoint one arbitrator within thirty (30) days after initiation of arbitration and the two arbitrators so appointed shall select a third arbitrator within forty-five (45) days after initiation of arbitration. In the event that the parties or the arbitrators fail to select arbitrators as required above, the AAA shall select such arbitrators. (iii) The AAA shall have the authority to disqualify any arbitrator who it determines not to be independent and impartial. The arbitrators shall be entitled to a fee commensurate with their fees for professional services requiring similar time and effort. (iv) The arbitrators shall conduct a hearing no later than sixty (60) days after initiation of the matter to arbitration, and a decision shall be rendered by the arbitrators within thirty (30) days of the hearing. At the hearing, the parties shall present such evidence and witnesses as they may choose, with or without counsel. Adherence to formal rules of evidence shall not be required but the arbitration panel shall consider any evidence and testimony that it determines to be relevant, in accordance with procedures that it determines to be appropriate.

The arbitrators may award legal or equitable relief, including but not limited to specific performance. (v) The parties agree that this submission and agreement to arbitrate shall be governed by and specifically enforceable in accordance with the laws of the State of Illinois. Arbitration may proceed in the absence of any party if prior written notice of the proceedings has been given to such party. The parties agree to abide by all decisions and determinations rendered in such proceedings. Such decisions and determinations shall be final and binding on all parties. All decisions and determinations may be filed with the clerk of one or more courts, state, federal or foreign having jurisdiction over the party against whom it is rendered or its property, as a basis of judgment. (vi) The arbitrators' fees and other costs of the arbitration shall be borne by the party against whom the award is rendered, except as the arbitration panel may otherwise provide in its written opinion. ARTICLE XXII. WAIVER ------ 22.1 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. ARTICLE XXIII. GOVERNING LAW ------------- 23.1 This Agreement shall be governed by and construed in accordance with the domestic laws of the State of Illinois, without reference to its choice of law principles.

If QWEST appoints an Intermediary, QWEST shall transfer the Existing Properties or such portion thereof as designated by QWEST to the Intermediary, and FRONTIER shall pay the IRU Fee with respect to the Existing Properties (as designated by QWEST) to the Intermediary; provided that QWEST agrees that such transfer shall be expressly ------------- subject to this Agreement, and that QWEST shall remain liable for performance under this Agreement to the same extent as if it had not appointed an Intermediary; provided that in such event QWEST shall indemnify and hold ------------- harmless FRONTIER from and against any and all loss, damage, cost or expense suffered, sustained or incurred by FRONTIER in connection with any such cooperation and/or payment of such IRU Fee to such Intermediary. 25.5 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.

The maximum pulling force to be applied to the fiber optic cable shall be 600 pounds. Bends of small radii (less than 20 times the outside diameter of the cable) and twists that may damage the cable shall be avoided during cable placement. The cable shall be lubricated and placed in accordance with the cable manufacturer specifications. A pulling swivel break-away rated at 600 pounds shall be used at all times. All splices will be contained in a handhole or manhole. A minimum of ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## meters of slack cable will be left in all intermediate handholes or manholes. A minimum of ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## meters of slack cable will be left in all splice locations. A minimum of ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## meters of slack cable will be left in all facility locations (i.e., POP sites, switch sites, regens or CEVs). 8.0 Manholes and Handholes. ---------------------- Manholes shall be placed in traveled surface streets and shall have locking lids. Handholes shall be placed in all other areas and be installed with a minimum of 18 inches of soil covering the lid. 9.0 EMS Markers. ----------- EMS markers shall be placed 6 inches directly above the lid of all buried handholes and assist points. EMS markers fabricated into the lids of handholes are acceptable. 10.0 Cable Markers (Warning Signs). ----------------------------- Cable markers (with the same information as buried cable warning tape) shall be installed at all changes in cable running line direction, splices, waterways, subsurface utilities, handholes and at both sides of street, highway, bridge or railroad crossings. At no time shall any markers be spaced more than 500 feet apart in metro areas and 1,000 feet apart in non- metro areas. Markers shall be positioned so that they can be seen from the location of the cable and generally set facing perpendicular to the cable running line. 11.0 Compliance. ---------- All work will be done in strict accordance with federal, state, local and applicable private rules and laws regarding safety and environmental issues, including those set forth by OSHA and the EPA. In addition, all work and the resulting fiber system will comply with the current requirements of all governing entities (FCC, NEC, DEC, and other national, state, and local codes). 12.0 As Built Drawings. ----------------- As-built drawings will contain a minimum of the following: 1) Information showing the location of running line, relative to permanent landmarks, including but not limited to, railroad mileposts, boundary crossings and utility crossings. 2) Splice locations 3) Manhole and handhole locations 4) Conduit information (type, length, expansion joints, etc.) 5) Cable information (manufacturer, type of fiber, type of cable, fiber assignments, final cable lengths) 6) Notation of all deviations from specifications (depth, etc.) 7) ROW detail (type, centerline distances, boundaries, waterways, road crossings, known utilities and obstacles) 8) Cable marker locations and stationing 9) Regeneration locations and floorplans to include FDP assignments (also labeled on site) Drawings will be updated with actual field data during and after construction. Metro areas scale shall not exceed 1 inch = 200 feet. Rural areas scale shall not exceed 1 inch = 500 feet. As-builts will be provided within ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## days after acceptance, in both hard copy and electronic format (Auto-CAD version 13.0 or later). Updates to the as-builts will be provided within ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## days of completion of change, like a relocation project. 13.0 Aerial Construction. ------------------- Subject to prior approval by both parties (which approval shall not be unreasonably withheld), aerial construction methods will only be used when buried construction techniques are impractical due to environmental conditions, schedule or economic considerations, right of way issues, or code restrictions. The parties acknowledge that aerial construction on utility towers (not utility poles) using optical groundwire or all dielectric self-support methods may be used without FRONTIER approval, provided QWEST agrees to give FRONTIER reasonable prior notice of its decision to use such aerial methods. Aerial design standards and construction techniques will conform with industry-accepted practices for aerial fiber optic cable systems. All aerial plant must comply with applicable national (NEC, NESC, etc.), state, and local codes. The fiber optic cable placed on an aerial system shall be armored and designed for aerial applications. The cable will be placed in accordance with manufacturer specifications. Cable tension will be monitored during placement. Cable rollers will be placed at a maximum interval of 35 feet. Cable expansion loops will be placed at every pole. Cable identification/warning tags will be placed at every pole. All cable splices will be buried in handholes or manholes. Cable sheath to suspension strand bonds and grounding will be performed at the first and last pole of the system and at 0.25 mile intervals. Fiber optic cable at all riser poles will be protected with galvanized steel U-guard from 12 inches below grade to a point 24 inches below the suspension strand. Conduit sweeps will be used to transition from the U- guard to either a handhole or manhole. All aerial plant will be designed and constructed with 10M EHS (Class A galvanized) suspension strand unless otherwise dictated by the pole owners or field conditions. The fiber optic cable will be doubled lashed to the suspension strand using 45 mil stainless lashing wire. Span length shall account for storm loading (wind and ice) in accordance with zones outlined in NESC code. Sags and tensions will be calculated in accordance with industry accepted practices and account for strand size, span length, ambient temperature at placement, and loading. The suspension strand will be tensioned with a strand dynamometer. A catenary suspension system may be used if the system exceeds maximum span length specifications. Prior to attachment to any existing pole line, the system will be inspected for compliance with applicable codes and standards, as well as the physical condition of the poles and existing hardware. Any make-ready work will be reviewed with the pole owner and specifically addressed prior to construction. If a pole line need be constructed, the preferred poles will be Class 4 (40 feet) and Class 5 (35 feet). Use of the preferred poles will make it unnecessary to calculate pole loading (horizontal, vertical, and bending moments) in most field conditions. Some unusual conditions may require the use of a stronger class pole. Depth of placement will be dictated by soil conditions, slope of terrain, and length of pole. Poles will be guyed in accordance with industry-accepted standards. All pole attachment hardware will be galvanized steel. Aerial cable will be placed below power attachments and above all other attachments unless otherwise dictated by the pole owner. Pole contact clearances and locations will be dictated by current NESC code and the presence of existing attachments; however, the following minimum objective clearances will apply: a) Power line - 40 inches (below) b) Non-current carrying power line - 30 inches c) Telephone, CATV, and other signal lines - 12 inches (above) Vertical clearances for crossings or parallel lines will be dictated by current NESC code; however, the objective clearance for most objects (roads, alleys, etc.) is 18 feet (at 100 degrees F) with the exception of railroad tracks and waterways which have an objective of 27 feet (at 100 degrees F). 14.0 Approval of Deviations From Specifications. ------------------------------------------ Qwest will seek the approval of FRONTIER, which approval shall not be unreasonably withheld or delayed, prior to undertaking any construction which will deviate from the Construction Specifications set forth in this Exhibit C. EXHIBIT D Fiber Cable Splicing, Testing and Acceptance Procedures ------------------------------------------------------- 1. All splices will be performed with an industry-accepted fusion splicing machine. Qwest will perform two stages of testing during the construction of a new fiber cable route. Initially, OTDR tests will be taken from one direction. As soon as fiber connectivity has been achieved to both regen sites, Qwest will verify and record the continuity of all fibers. Qwest will take and record power level readings on all fibers in both directions. Qwest will bi- directional OTDR test all fibers. 2. During the initial construction, it is only possible to measure the fiber from one direction. Because of this, splices will be qualified during initial construction with an OTDR from only one direction. The profile alignment system or light injection detection system on the fusion splicer may be used to qualify splices as long as a close correlation to OTDR data is established. The pigtails will also be qualified at this stage using an OTDR and a minimum 1 km launch reel. All measurements at this stage in construction will be taken at 1550 nm. 3. After Qwest has provided end-to-end connectivity on the fibers, bi- directional span testing will be done. These measurements must be made after the splice manhole or handhole is closed in order to check for macro-bending problems. Continuity tests will be done to verify that no fibers have been "frogged" or crossed in any of the splice points. Once the pigtails have been spliced, loss measurements will be recorded using an industry-accepted laser source and a power meter. OTDR traces will be taken and splice loss measurements will be recorded. Qwest will also store OTDR traces on diskette and on data sheets. Laser Precision format will be used on all traces. Qwest will provide three copies of all data sheets and tables, and one set of diskettes with all traces. a. The power loss measurements shall be made at 1550 nm, and performed bi-directionally. b. OTDR traces shall be taken in both directions at 1550 nm. 4. The splicing standards are as follows: a. The loss value of the pigtail connector and its associated splice will not exceed 0.50 dB. This value does not include the insertion loss from its connection to the FDP. For values greater than this, the splice will be broken and respliced until an acceptable loss value is achieved. If, after five attempts, Qwest is not able to produce a loss value less than 0.50 dB, the splice will be marked as Out-of-Spec ("OOS") on the data sheet. Each splicing attempt shall be documented on the data sheet. b. During initial uni-directional OTDR testing, the objective for each splice is a loss of 0.15 dB or less. If, after three attempts, Qwest is not able to produce a loss value of less than 0.15 dB, then 0.25 dB will be acceptable. If, after two additional attempts, a value of less than 0.25 dB is not achievable, then the splice will be marked as OOS on the data sheet. Each splicing attempt shall be documented on the data sheet. c. During end-to-end testing of a span (a span shall be FDP to FDP), the objective for each splice is a bi-directional average loss of 0.15 dB or less. d. The standard for each fiber within a span shall be an average bi- directional loss of 0.10 dB or less for each splice. For example, if a given span has 10 splices, each fiber shall have total bi-directional loss (due to the 10 splices) of 1.0 dB or less. Each individual splice may have a bi-directional loss of 0.15 dB or less, but the average bi-directional splice loss across the span must be 0.10 dB or less. 5. The entire fiber optic cable system shall be properly protected from foreign voltage and grounded with an industry-accepted system. The current system in use by Qwest is depicted in the attached schematic-DWG No. SAH-1 (typical for Surge Arrestor HH Placement). 6. Customer fiber assignments will be consecutive in count and in a separate buffer tube (or ribbon or fiber bundles) from others. The maximum number of fibers within a single buffer tube (or ribbon or fiber bundles) shall be 12. 7. The fibers shall be terminated to the FDP with Ultra FC-PC connectors, unless another type of connector is specified. The pigtails shall be manufactured with the same glass as the backbone cable to minimize splice loss. EXHIBIT E FIBER SPECIFICATIONS [This exhibit contains product specification information that is largely set forth in graphic format.] EXHIBIT E-1 [MAP APPEARS HERE] Exhibit E-1 is a map of the United States with the heading "Fiber Deployment Diagram" showing state lines and routes of the fiber optic network upon completion. The legend shows that a tan line represents Fiber not designated, a solid blue line is LS Fiber (Existing), a broken blue line is LS Fiber (Planned), a broken red line is Lucent TWF (Planned), a solid turquoise line is DS Fiber (Existing), and one inch equals 225 miles.

Unscheduled Maintenance shall commence with respect to each Segment upon the effective date of the grant of the IRU therein, as provided in the IRU Agreement. Unscheduled Maintenance shall consist of: (i) "Emergency Unscheduled Maintenance" in response to an alarm identification by Service Provider's Operations Center, notification by Service Recipient or notification by any third party of any failure, interruption or impairment in the operation of the Qwest System, or any event imminently likely to cause the failure, interruption or impairment in the operation of the Qwest System. (ii) "Non-Emergency Unscheduled Maintenance" in response to any potential service-affecting situation to prevent any failure, interruption or impairment in the operation of the Qwest System. Service Recipient shall immediately report the need for Unscheduled Maintenance to Service Provider in accordance with procedures promulgated by Service Provider from time to time. Service Provider will log the time of Service Recipient's report, verify the problem and will dispatch personnel immediately to take corrective action. 2. Operations Center. ----------------- Service Provider shall operate and maintain a Operations Center ("OC") staffed twenty-four (24) hours a day, seven (7) days a week by trained and qualified personnel. Service Provider's maintenance employees shall be available for dispatch twenty-four (24) hours a day, seven (7) days a week. Service Provider shall have its first maintenance employee at the site requiring Emergency Unscheduled Maintenance activity within ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## after the time Service Provider becomes aware of an event requiring Emergency Unscheduled Maintenance, unless delayed by circumstances beyond the reasonable control of Service Provider. Service Provider shall maintain a toll-free telephone number to contact personnel at the OC. Service Provider's OC personnel shall dispatch maintenance and repair personnel along the system to handle and repair problems detected in the Qwest System, (i) through the Service Recipient's remote surveillance equipment and upon notification by Service Recipient to Service Provider, or (ii) upon notification by a third party. 3. Cooperation and Coordination. ---------------------------- (a) Service Recipient shall utilize an Operations Escalation List, as updated from time to time, to report and seek immediate initial redress of exceptions noted in the performance of Service Provider in meeting maintenance service objectives. Service Recipient will, as necessary, arrange for unescorted access for Service Provider to all sites of the Qwest System, subject to applicable contractual, underlying real property and other third-party limitations and restrictions. (c) In performing its services hereunder, Service Provider shall take workmanlike care to prevent impairment to the signal continuity and performance of the Qwest System. The precautions to be taken by Service Provider shall include notification to Service Recipient. In addition, Service Provider shall reasonably cooperate with Service Recipient in sharing information and analyzing the disturbances regarding the cable and/or fibers. In the event that any Scheduled or Unscheduled Maintenance hereunder requires a traffic roll or reconfiguration involving cable, fiber, electronic equipment, or regeneration or other facilities of the Service Recipient, then Service Recipient shall, at Service Provider's reasonable request, make such personnel of Service Recipient available as may be necessary in order to accomplish such maintenance, which personnel shall coordinate and cooperate with Service Provider in performing such maintenance as required of Service Provider hereunder. (d) Service Provider shall notify Service Recipient at least ten (10) business days prior to the date in connection with any PSWP of any Scheduled Maintenance and as soon as possible after becoming aware of the need for Unscheduled Maintenance. Service Recipient shall have the right to be present during the performance of any Scheduled Maintenance or Unscheduled Maintenance so long as this requirement does not interfere with Service Provider's ability to perform its obligations under this Agreement. In the event that Scheduled Maintenance is canceled or delayed for whatever reason as previously notified, Service Provider shall notify Service Recipient at Service Provider's earliest opportunity, and will comply with the provisions of the previous sentence to reschedule any delayed activity. 4. Facilities. ---------- (a) Service Provider shall maintain the Qwest System in a manner which will permit Service Recipient's use, in accordance with the terms and conditions of the IRU Agreement, of the IRU, the Frontier Fibers and the Associated Property required to be provided under the terms of the IRU Agreement. Except to the extent otherwise expressly provided in the IRU Agreement, Service Recipient will be solely responsible for providing and paying for any and all maintenance of all electronic, optronic and other equipment, materials and facilities used by Service Recipient in connection with the operation of the Dark Fibers, none of which is included in the maintenance services to be provided hereunder. 5. Cable/Fibers. ------------ (a) Service Provider shall perform appropriate Scheduled Maintenance on the Cable contained in the Qwest System in accordance with Service Provider's then current preventative maintenance procedures as agreed to by Service Recipient, which shall not substantially deviate from standard industry practice. Service Provider shall have qualified representatives on site any time Service Provider has reasonable advance knowledge that another person or entity is engaging in construction activities or otherwise digging within five (5) feet of the Cable. (c) Service Provider shall maintain sufficient capability to teleconference with Service Recipient during an Emergency Unscheduled Maintenance in order to provide regular communication during the repair process. When correcting or repairing Cable discontinuity or damage, including but not limited to in the event of Emergency Unscheduled Maintenance, Service Provider shall use reasonable efforts to repair traffic-affecting discontinuity within four (4) hours after the Service Provider maintenance employee's arrival at the problem site. In order to accomplish such objective, it is acknowledged that the repairs so effected may be temporary in nature. In such event, within twenty-four (24) hours after completion of any such Emergency Unscheduled Maintenance, Service Provider shall commence its planning for permanent repair, and thereafter promptly shall notify Service Recipient of such plans, and shall implement such permanent repair within an appropriate time thereafter. Restoration of open fibers on fiber strands not immediately required for service shall be completed on a mutually agreed-upon schedule. If the fiber is required for immediate service, the repair shall be scheduled for the next available Planned Service Work Period (PSWP). (d) In performing repairs, Service Provider shall comply with the splicing specifications as set forth in Exhibit D. Service Provider shall provide to Service Recipient any modifications to these specifications as may be necessary or appropriate in any particular instance for Service Recipient's approval, which approval shall not be unreasonably withheld. (e) Service Provider's representatives that are responsible for initial restoration of a cut Cable shall carry on their vehicles the typically appropriate equipment that would enable a temporary splice, with the objective of restoring operating capability in as little time as possible. Service Provider shall maintain and supply an inventory of spare Cable in storage facilities supplied and maintained by Service Provider at strategic locations to facilitate timely restoration. 6. Planned Service Work Period (PSWP). ---------------------------------- Scheduled Maintenance which is reasonably expected to produce any signal discontinuity must be coordinated between the parties. Generally, this work should be scheduled after midnight and before 6:00 a.m. local time. Major system work such as fiber rolls and hot cuts will be scheduled for PSWP weekends. A calendar showing approved PSWP will be agreed upon in the last quarter of every year for the year to come. The intent is to avoid jeopardy work on the first and last weekends of the month and high-traffic holidays. 7. Restoration. ----------- (a) Service Provider shall respond to any interruption of service or a failure of the Dark Fibers to operate in accordance with the specifications set forth in Exhibit D (in any event, an "Outage") as quickly as possible (allowing for delays caused by circumstances beyond the reasonable control of Service Provider) in accordance with the procedures set forth herein. When restoring a cut Cable in the Qwest System, the parties agree to work together to restore all traffic as quickly as possible. Service Provider, promptly upon arriving on the site of the cut, shall determine the course of action to be taken to restore the Cable and shall begin restoration efforts. Service Provider shall splice fibers tube by tube or ribbon by ribbon or fiber bundle by fiber bundle, rotating between tubes or ribbons operated by the separate Interest Holders (as defined in paragraph 9(a)), including Service Recipient, in accordance with the following described priority and rotation mechanics; provided that, lit fibers in all buffer tubes or ribbons or fiber -------------- bundles shall have priority over any dark fibers in order to allow transmission systems to come back on line; and provided further that, Service Provider will --------------------- continue such restoration efforts until all lit fibers in all buffer tubes or ribbons are spliced and all traffic restored. In general, priority among Interest Holders affected by a cut shall be determined on a rotating restoration-by-restoration and Segment-by-Segment basis, to provide fair and equitable restoration priority to all Interest Holders, subject only to such restoration priority to which Qwest is contractually obligated prior to the date of the Agreement. Service Provider shall use all reasonable efforts to implement a Qwest System-wide rotation mechanism on a Segment-by-Segment basis so that the initial rotation order of the Interest Holders in each Segment is varied (from earlier to later in the order), such that as restorations occur, each Interest Holder has approximately equivalent rotation order positions across the Qwest System. Additional participants in the Qwest System that become Interest Holders after the date hereof shall be added to the restoration rotation mechanism. (c) The goal of emergency restoration splicing shall be to restore service as quickly as possible. This may require the use of some type of mechanical splice, such as the "3M Fiber Lock" to complete the temporary restoration. Permanent restorations will take place as soon as possible after the temporary splice is complete. 8. Subcontracting. -------------- Service Provider may subcontract any of the maintenance services hereunder; provided that Service Provider shall require the subcontractor(s) to perform in accordance with the requirement and procedures set forth herein. The use of any such subcontractor shall not relieve Service Provider of any of its obligations hereunder. 9. Fees and Costs. --------------- (a) Scheduled Maintenance Fees. The fees payable for any and all -------------------------- Scheduled Maintenance hereunder shall be determined in accordance with the following provisions. During any time after the Acceptance Date for any Segment but subject to paragraph 10 below, Qwest shall be the Service Provider and provide Scheduled Maintenance at a cost not to exceed $ ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## per route mile per year, subject to the CPI adjustment described below (the "Qwest Fixed Fee") and Unscheduled Maintenance as provided in subparagraph 9 below. The Scheduled Maintenance fee payable by Service Recipient shall be equal to a pro rata share of Qwest's Costs, based first upon the number of conduits so maintained by Qwest and included in such Costs and second upon the number of Interest Holders (as defined in Section 10.4 of the Agreement) in the portion of the Qwest System so maintained by Qwest and included in such Costs; provided however, the total fee shall in no event exceed the amount of the Qwest Fixed Fee as adjusted by the CPI-U Adjustment. A quarter of the first such Scheduled Maintenance fee with respect to each Segment will be due and payable thirty (30) days after the Acceptance Date with respect to such Segment. Thereafter, one quarter of such fee shall be due quarterly. All fees shall be paid by Service Recipient within thirty (30) days of receipt of invoice therefor. The Qwest Fixed Fee, if applicable, may be adjusted annually, in Qwest's sole discretion, beginning with the first anniversary date of the execution date of this Agreement, for increases in the United States Bureau of Labor Statistics, CPI-U All Services Index (unadjusted), as originally published. Said adjustment shall be hereinafter referred to as "CPI-U Adjustment". Such fee, as adjusted by the CPI-U Adjustment, shall be equal to the product of the fee specified herein multiplied by the fraction (i) whose numerator is the CPI-U All Services for March of the previous calendar year for which the adjustment to the fee is being made, and (ii) whose denominator is the CPI-U All Services for March of the preceding year. The adjusted fee shall remain in effect until the next annual fee is due, when a new adjusted fee fixed pursuant to this provision shall become effective. In no event shall the amount of the fee as adjusted pursuant to this provision be less than the amount of fee in effect for the immediately-preceding year. The parties agree that the Index for March 1995 is defined as 151.4. In the event that the Bureau of Labor Statistics (or any successor organization) changes the current base of the CPI-U from 1982-84 = 100, the calculation of a fee under this provision shall be adjusted to ensure that Qwest receives the same amount as it would have had, had the base not been changed. In the event the Bureau of Labor Statistics or any successor organization no longer publishes the CPI-U, Qwest, subject to Service Recipient's agreement (which shall not be unreasonably withheld), designate the statistical index it deems most appropriate for calculation of adjustments to a fee and, from the date the CPI-U ceased to be published, such index shall be used to make adjustments in a fee under this provision. On and after the second anniversary of the execution of the Agreement, if either of FRONTIER or QWEST determines that the Scheduled and Unscheduled Maintenance to be provided hereunder should be put out to competitive bid process, then such party shall notify the other of such determination, and thereafter may obtain at least three bids in writing from national or regional maintenance providers of sound business and financial reputation to perform the Scheduled and Unscheduled Maintenance hereunder. Bids for maintenance services must be for both Scheduled and Unscheduled Maintenance and must be for portions of the QWEST System covering at least 1,000 contiguous route miles to provide for the most competitive bidding and the best overall maintenance practices at the lowest possible cost to Service Recipient. If a majority of the Interest Holders agree on acceptable bids, QWEST shall be entitled to elect either to continue to provide the Scheduled and Unscheduled Maintenance, or to subcontract the Scheduled and Unscheduled Maintenance obligations hereunder to the lowest such acceptable bidder, in either of which cases the Scheduled Maintenance fee payable by Service Recipient shall be equal to a pro rata share, based first upon the number of conduits maintained by QWEST and included in such Costs and second upon the Interest Holders in the portion of the QWEST System covered by the bid, of the sum of the lowest acceptable bid price plus a 10% G&A overhead allowance with QWEST in any such case retaining such overhead allowance. (b) Unscheduled Maintenance Fees. If the aggregate amount of the ---------------------------- Costs of Unscheduled Maintenance required as a result of any single event or multiple, closely-related events is less than ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## ), such Costs shall be borne by Service Provider. For any other Unscheduled Maintenance, the Costs thereof shall be allocated among the various Interest Holders in the conduit, cable and/or fibers affected thereby as follows: (i) Costs of Unscheduled Maintenance solely to or affecting a conduit or cable which houses fibers of a single Interest Holder shall be borne 100% by such Interest Holder; (ii) Costs of Unscheduled Maintenance to or affecting a conduit which houses multiple innerduct conduits, not including such Costs attributable to the repair or replacement of fiber therein, shall be borne proportionately by the Interest Holders in each of the affected innerduct conduits based on the ratio that such affected conduit bears to the total number of affected innerduct conduits, and (iii) Costs of Unscheduled Maintenance attributable to the repair or replacement of fiber, including the acquisition, installation, inspection, testing and splicing thereof, shall be borne proportionately by the Interest Holders in the affected fiber, based on the ratio that the number of affected fibers subject to the interest of each such Interest Holder bears to the total number of affected fibers. All such Costs which are allocated to Service Recipient pursuant to the foregoing provisions shall be the responsibility of and paid by Service Recipient within thirty (30) days after its receipt from Service Provider of an invoice therefor. (c) Costs. "Costs" means the actual, direct costs paid or payable in ----- accordance with the established accounting procedures generally used by each party, as the case may be, and which it utilizes in billing third parties for reimbursable projects, which costs shall include, without limitation, the following: (i) labor costs, including wages and salaries, and benefits and overhead allocable to such labor costs (overhead allocation percentage shall not exceed the lesser of (x) the percentage Service Provider typically allocates to its internal projects or (y) thirty percent (30%), and (ii) other direct costs and out-of-pocket expenses on a pass-through basis (e.g., equipment, materials, supplies, contract services, etc.). 10. Term. ---- Service Provider's obligation to perform maintenance on the relevant portion of the Qwest System shall be for an initial term expiring ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## , and unless a different Service Provider is selected by the Interest Holders under a mutually agreed selection process, then Qwest shall be the Service Provider. Thereafter, Qwest shall have no obligation to provide Scheduled or Unscheduled Maintenance hereunder, but shall be entitled to participate in any process selected by the Interest Holders as a potential Service Provider.

("FRONTIER") (collectively referred to as the "Parties"). Recitals A. QWEST and FRONTIER are parties to an IRU Agreement dated as of October 18, 1996 (the "FRONTIER IRU") regarding FRONTIER's right to use twenty four (24) dark fibers comprising a part of a continuous fiberoptic communications system being constructed by QWEST (the "QWEST System"). B. Pursuant to Section 1.4 of the FRONTIER IRU, FRONTIER was granted a right to acquire the right to use an additional twenty four (24) dark fibers in the QWEST System. C. In lieu of exercising its rights under Section 1.4 of the FRONTIER IRU, FRONTIER has entered into negotiations with QWEST and GTE Intelligent Network Services, Inc. ("GTE") whereby GTE will acquire the right to use twenty four (24) dark fibers in the QWEST System pursuant to an IRU agreement with QWEST (the "GTE IRU"). D. Pursuant to the GTE IRU, GTE agrees to pay QWEST $ ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## per route mile of the QWEST System (the "GTE IRU Fee"). E. The Parties desire to address their mutual rights and obligations with regard to the GTE IRU, the GTE IRU Fee and other aspects of their relationship under the FRONTIER IRU. Agreement NOW, THEREFORE, in consideration of the mutual promises set forth herein, the Parties agree as follows: 1. Definitions.

The allocation provided for in this paragraph shall pertain only to the GTE IRU Fee set forth above and shall not be applicable to payments received by QWEST under the GTE IRU for regeneration and terminal facilities or maintenance costs or other costs not associated with GTE's IRU in 24 fibers in QWEST's 12,766 mile network. 3. Contingencies. The obligations of the Parties under this Agreement are contingent upon the execution of the GTE IRU by GTE and QWEST and the approval thereof by FRONTIER, which approval shall not be unreasonably withheld.

At any time prior to the execution date, FRONTIER may give notice of any objection to the terms of such agreement which materially affect the compensation to be received by FRONTIER from the GTE IRU or the Obligations being guaranteed by FRONTIER under such agreement. The failure of FRONTIER to give timely notice of an objection shall constitute approval of the GTE IRU by FRONTIER.
