DATED: December 16, 2005
National Metro Dark Fiber Agreement

This Fifth Amendment (the “5th Amendment”) to the Indefeasible Right of Use
Agreement and Master Service Agreement Dark Fibers is by and between Zayo Group,
LLC (“Zayo”) and tw telecom holdings inc. on behalf of itself and its Affiliates
(“User”). As used herein, Zayo and User may be referred to, each, as a “Party,”
and collectively, the “Parties.”

RECITALS

WHEREAS, User and Zayo previously entered into that certain Indefeasible Right
of Use Agreement and Master Service Agreement Dark Fibers (“Agreement”) dated
December 16, 2005, wherein the Parties defined the terms and conditions under
which Zayo would provide User with certain indefeasible rights of use in User
Dark Fibers in the Zayo System, all as is more specifically set forth in the
Agreement; and
WHEREAS, User desires to enter into a national agreement to establish defined
terms and conditions for User to obtain metropolitan dark fiber and related
facilities along specific segments from Zayo; and
WHEREAS, Zayo desires to enter into such contract with User; and
WHEREAS, User and Zayo now mutually desire to amend the Agreement accordingly.
NOW THEREFORE, in consideration of the foregoing and for covenants, promises and
other good and valuable consideration, the receipt and sufficiency of which is
hereby acknowledged, User and Zayo agree to amend the Agreement as follows:
1.    Intent.
a. This 5th Amendment is to define specific terms and conditions for User to
order and Zayo to provide User Dark Fibers in certain metropolitan markets. Upon
execution of this 5th Amendment, the Parties shall use commercially reasonable
efforts to prepare and execute Service Orders for the initial User Dark Fibers
identified in Exhibit B within sixty

Exchange Commission together with such request for confidential treatment.

(60) days, subject to any additional time that may be required to resolve issues
the Parties are diligently working to resolve. This 5th Amendment shall apply
only to the Service Orders described immediately above (together with the Option
Fibers and ROFR Fibers identified in each such Service Orders and any Added
Route Fibers ordered in accordance with Section 4 of this Amendment) for those
metropolitan markets, route segments within each market, and related route
mileage and fiber counts specifically identified in Exhibit B. The Parties shall
enter into Service Orders in the template specified in Exhibit C for User Dark
Fibers ordered in accordance with this Amendment.
b. User and Zayo and its Affiliates are party to various agreements, service
orders, product orders, ..etc., under which Zayo and its Affiliates lease,
license and/or grant an IRU to User for metro dark fibers (collectively “Metro
Dark Fiber Agreements”). Where identified herein, this Amendment will provide
the terms and conditions for some or all of the existing metro dark fiber and
facilities ordered pursuant to the Metro Dark Fiber Agreements to be provided in
accordance with the Agreement.
c. Notwithstanding Section 3.1 of the Agreement, the Parties intend that Zayo
will grant User a lease, as defined by Colorado law (“Lease”), in the Service
Orders under this 5th Amendment, and not an IRU. A Service Order shall not be
construed to result in the transfer of title to any part of the User Dark Fiber
to User or in the creation of a “security interest” within the meaning of
Colorado law. Upon the expiration or termination of a Lease, all rights of User
to use the relevant User Dark Fibers shall cease, all rights to the use of the
User Dark Fibers shall revert to Zayo, and Zayo shall owe User no further
duties, obligations or consideration. For purposes of the Service Orders under
this 5th Amendment, wherever appropriate, the term “IRU” as specified in the
Agreement shall refer to a “Lease”.
2.    Ordering and Delivery. The process by which User will order and Zayo will
deliver the User Dark Fibers in Section 1a above is as follows:
a.    Commencing upon the Amendment Effective Date, User and Zayo will use
commercially reasonable efforts to prepare and execute within 60 days the
Service Orders necessary to provide User with the initial User Dark Fibers
identified in Exhibit B and along the routes depicted in Exhibit A of this 5th
Amendment (collectively “Initial Fibers”) subject to any additional time that
may be required to resolve issues the Parties are diligently working to resolve.
User will be allowed up to [***] Connecting Points across all markets to allow
connectivity of User Media to the initial User Dark Fiber. Specific Connection
Points to be identified in Exhibits B and C of the applicable Service Orders.
The Parties acknowledge that the amount of Initial Fibers may be adjusted as
mutually agreed based on the splicing configurations requested by User provided
that such adjustment shall not result in a reduction of the Fiber Mileage
associated with the Initial Fibers. Each metropolitan city will have a Service
Order and each Service Order will list each segment (“Segment”) for that city,
all as generally described in Exhibit A of this 5th Amendment. Each Service
Order for the Initial Fibers shall be in the form described in Exhibit C of this
5th Amendment. No Service Order will have a Committed Delivery Date later than
December 31, 2014.

Portions of this Exhibit have been redacted pursuant to a request for
confidential treatment under Rule 24b-2 of the General Rules and Regulations of
the Securities Exchange Act of 1934, as amended. Omitted information, marked
“[***]” in this Exhibit, has been filed separately with the Securities and
Exchange Commission together with such request for confidential treatment.

b.    Upon the Effective Date of a Service Order, Zayo will promptly commence
all necessary work to complete the construction, splicing and acceptance testing
of all Initial Fibers by the Committed Delivery Date. Notwithstanding the above,
User understands and agrees that User will not have use of all Initial Fibers as
of the Acceptance Date, but will follow the usage schedule as further described
in Exhibit D (“Fiber Usage Ramp”). User shall notify Zayo if User desires to use
additional Initial Fibers in excess of the Fiber Usage Ramp on one or more
Segments, and thereafter User shall pay the full monthly Lease Fee for such
Segment(s), User will continue doing so for the remainder of the Term and User
will have use of all Initial Fibers on such Segment(s). In the event Zayo
reasonably determines that User is using more Initial Fibers than specified by
the Fiber Usage Ramp on one or more Segments without notifying Zayo in advance
as provided in this Section 2b. above, then Zayo will immediately commence
invoicing User for the full monthly Lease Fee for all Initial Fibers for such
Segment(s), User will timely pay such invoices, User will continue doing so for
the remainder of the Term, and User will have use of all Initial Fibers on the
affected Segment(s) beginning on the date that User is responsible for the full
monthly Lease Fee for the affected Segment(s). If, at any time, Zayo reasonably
determines that User, without notifying Zayo in advance as provided in this
Section above, is using more Initial Fibers than the applicable amount of
Initial Fibers available to User as specified by the Fiber Usage Ramp on [***]
of the total fiber miles specified in any Service Order, then Zayo will
immediately commence invoicing User for the [***] Lease Fee for all Initial
Fibers specified on such Service Order, and User will timely pay such invoices,
User will continue doing so for the remainder of the Term, and User will have
use of all Initial Fibers specified in the applicable Service Order beginning on
the date that User is responsible for the full monthly Lease Fee for the
affected Service Order. If, at any time, Zayo reasonably determines that User,
without notifying Zayo in advance as provided above, is using more Initial
Fibers than the applicable amount of Initial Fibers available to User as
specified by the Fiber Usage Ramp on [***] of the total fiber miles associated
with the Initial Fibers, then Zayo will immediately commence invoicing User for
the [***] Lease Fee for all Initial Fibers, and User will timely pay such
invoices, User will continue doing so for the remainder of the Term, User will
continue doing so for the remainder of the Term, and User will have use of all
Initial Fibers beginning on the date that User is responsible for the [***]
Lease Fee.
c.    The Parties mutually acknowledge that Zayo’s fiber records could be in
error on approximately [***]% of the Segments and such record errors could
impact fiber availability. In addition, certain Segments have not been fully
constructed as of the Amendment Effective Date and the availability of those
Segments may be impacted by modifications to the construction plan. As such, the
availability of the Initial Fibers and Option Fibers (collectively “Available
Fibers”) is subject to a final verification during implementation of each
metropolitan market and that fewer Available Fibers may be available for User
than reflected in Exhibit B. Provided that User uses commercially reasonable
efforts to prepare and execute Service Orders for the initial User Dark Fibers
identified in Exhibit B within sixty (60) days of the Amendment Effective Date
subject to any additional time that may be required to resolve issues the
Parties are diligently working to resolve, Zayo shall use good faith efforts to
not sell or lease dark fiber inventory after

Exchange Commission together with such request for confidential treatment.

the execution of this 5th Amendment, but prior to the execution of the Service
Orders for the Initial Fibers, that reduces the Available Fibers specified in
Exhibit B. Accordingly, due to lack of fiber availability, Zayo shall have the
right to reduce the number of Available Fiber miles in one or more Segment(s) in
a given Service Order (“Deselect”) by [***] in those metropolitan markets
identified in Exhibit B with [***] or more Initial Fiber miles, or by [***] in
those metropolitan markets identified in Exhibit B with less than [***] Initial
Fiber fiber miles; provided however that in no event shall Zayo cumulatively
Deselect more than [***] of the total Initial Fiber mileage, or more than [***]
of the total Optional Fiber fiber mileage reflected in Exhibit B. Zayo will
promptly notify User of the Deselect as soon as Zayo confirms the fiber
availability for a Segment. Zayo will not be penalized in any way for a
Deselect. Zayo will confirm to User in writing once it has identified all
Deselect(s) applicable to a Service Order (“Deselect Notice”). User shall have
twenty one (21) days after receipt of the Deselect Notice to notify Zayo in
writing of any Segments and/or User Dark Fibers that, in User’s reasonable
discretion, are materially and adversely impacted by the relevant Zayo
Deselect/s (“User Deselect Notice”). For the avoidance of doubt, “materially and
adversely impacted”, for purposes of this Section 2c, shall mean an interruption
in fiber continuity, User’s inability to use User Dark Fibers as originally
intended and/or adverse impact on User’s ability to use User Dark Fibers
commercially. Unless otherwise agreed upon by the Parties, the affected Service
Order shall be revised, without penalty to either Party, to reflect the
reductions in Segments and/or User Dark Fibers specified in the applicable
Deselect Notice and User Deselect Notices and to reflect the modified splicing
configurations.
d.    Except as otherwise provided herein, the Parties mutually acknowledge that
billing for a Service Order will occur upon the Acceptance Date of the last
Segment in a Service Order. Notwithstanding the foregoing, Zayo will notify User
if Zayo, despite making commercially reasonable good faith efforts, is unable to
deliver one (1) or more Segments of a given Service Order in accordance with the
applicable specifications, and the Parties will work together in good faith to
identify the Segments and User Dark Fibers delivered in accordance with the
applicable specifications that are not adversely impacted by such failure
(“Non-Impacted User Dark Fibers”). Provided that Non-Impacted User Dark Fibers
represent at least [***] of the fiber mileage specified in the applicable
Service Order for Service Orders with [***] or more Initial Fiber miles, or
represent at least [***] of the fiber mileage specified in the applicable
Service Order for Service Orders with less than [***] fiber miles, Zayo may
present a Completion Notice for the Non-Impacted User Dark Fibers and following
User’s acceptance Zayo may begin(i) invoicing for the Service Order with respect
to the accepted Non Impacted User Dark Fibers; (ii) Zayo will continue to make
good faith efforts to complete the remaining Segments and/or negotiate in good
faith with User to amend the Service Order to remove such Segments or identify
alternate Segments (when agreement is reached between the Parties the Parties
will execute an amendment to the Service Order to remove the remaining Segments
and/or include the additional Segments); (iii) the initial Term of all User Dark
Fibers specified in the Service Order will be twenty (20) years from the
Acceptance Date of the Non-Impacted User Dark Fibers (iv) billing for any
remaining Segments and any Segments and/or User Dark Fibers adversely impacted
by such remaining Segments will begin upon the Acceptance Date of the remaining

Fiber miles. Notwithstanding anything to the contrary, User Dark Fibers shall
immediately be deemed Accepted, and billing shall immediately begin for all
affected Segments, in the event that User utilizes the User Dark Fibers for any
purpose other than testing prior to the Acceptance Date.

3.    Option Fibers, Right of First Refusal, Purchase Commitment.
a.    For the initial [***] ([***]) months of the initial Term of a Service
Order for the Initial Fibers for each of the metropolitan cities identified in
Exhibit G (“F Markets”), User shall have the right to Lease additional dark
fibers (“Option Fibers”) for each Segment Group as specified in the relevant
Service Order. For the avoidance of doubt, User may only order Option Fibers in
complete Segment Group configurations and must order all Segments of each
Segment Group it is ordering, except in the case where (i) there are no
remaining Option Fibers in one or more Segments in a Segment Group and in such
case the lack of Option Fibers in such Segment(s) shall not restrict User’s
ability to Lease Option Fibers in the remaining Segment(s), but no less than all
the remaining Segments, within such Segment Group; and (ii) the Segment Group is
identified as a “Single Segment Group” and in such case User may order such
Option Fiber in single Segment configurations and is not required to order all
Segments within the Single Segment Group. The specific maximum fiber count for
the Option Fibers of each Segment is further described in Exhibit B (subject to
modification as allowed in Section 2, herein). In the event that User desires to
exercise this option for all or some of the Option Fibers for a Segment Group in
an F Market, User will provide a written request to Zayo that includes the
number of fibers requested (in no event less than 2 fibers in any Segment Group)
and the Parties will execute a Service Order and Zayo will promptly deliver the
requested Option Fibers in accordance with the testing and acceptance provisions
set forth in this Agreement and the Option Fiber will become User Dark Fiber
hereunder. For purposes of this 5th Amendment, “Segment Group” shall mean one or
more Segments belonging to a specific Segment Group number as specified in
Exhibit B.
b.    For the initial [***] ([***])months of the initial Term of a Service Order
for the Initial Fibers for each of the metropolitan cities identified in Exhibit
H (“T Markets”), User shall have the right to Lease Option Fibers for each
Segment Group as specified in the relevant Service Order. For the avoidance of
doubt, User may only order Option Fibers and ROFR Fibers in complete Segment
Group configurations and must order all Segments of each Segment Group it is
ordering, except in the case where (i) there are no remaining Option Fibers or
ROFR Fibers in one or more Segments in a Segment Group and in such case the lack
of Option Fibers or ROFR Fibers in such Segment(s) shall not restrict User’s
ability to Lease Option Fibers or ROFR Fibers in the remaining Segment(s), but
no less than all the remaining Segments, within such Segment Group; (ii) the
Segment Group is identified as a “Single Segment Group” and in such case User
may order such Option Fiber or ROFR Fiber in single Segment configurations and
is not required to order all Segments within the Single Segment Group and (iii)
User is Leasing ROFR Fibers in accordance with Sections 3c(ii) and 3c(iii) below
and in such case User shall comply with the specifications contained in Sections
3c(ii) and 3c(iii) below. The specific maximum fiber count for the Option Fibers
of each Segment is further described in Exhibit B (subject to modification as
allowed in Section 2, herein). In the event that User desires to exercise this
option for all or some of the Option Fibers for a Segment Group in a T Market,
User will provide a written request to Zayo that includes the number of fibers
requested (in no event less than 2 fibers in any Segment Group) and the Parties
will use commercially reasonable efforts to prepare and execute a Service Order
within fifteen (15) days thereafter subject to any additional time that may be
required to resolve issues the Parties are diligently working to resolve. Upon
execution of the Service Order, Zayo will promptly deliver

Exchange Commission together with such request for confidential treatment.

the requested Option Fibers in accordance with the testing and acceptance
provisions set forth in this Agreement and the Option Fiber will become User
Dark Fiber hereunder.
c.     For the period beginning on the expiration of the initial [***] ([***])
months of the initial Term of each Service Order for a T Market and ending on
the expiration of the initial [***] of the initial Term (“RFR Term”), User shall
have the right of first refusal as specified in this Section 3c to lease
additional fibers located on each Segment Group in a T Market in an amount equal
to the remaining Option Fibers for such Segment Group as further described in
Exhibit B, less any Option Fibers previously leased to User in accordance with
Section 3 b above (“ROFR Fibers”).
(i) During the RFR Term, User may exercise its right of first refusal for all or
some of the ROFR Fibers in a Segment Group in a T Market by providing a written
request to Zayo that includes the number of ROFR Fibers requested (in no event
less than 2 fibers in any Segment Group). Thereafter, but based on the remaining
amount of ROFR Fibers for such Segment Group that are available to User in
accordance with this Section 3c , the Parties will use commercially reasonable
efforts to prepare and execute a Service Order within [***] days thereafter
subject to any additional time that may be required to resolve issues the
Parties are diligently working to resolve and, after execution of a Service
Order and Zayo will promptly deliver the requested ROFR Fibers in accordance
with the testing and acceptance provisions set forth in this Agreement, the
requested ROFR Fibers will become User Dark Fiber hereunder, and the amount of
any remaining ROFR Fibers in the applicable Segments shall be reduced by the
number of ROFR Fibers leased. For clarity, the ROFR Fibers shall refer only to
the number of fibers in a Segment Group which are available for User to lease as
ROFR Fibers hereunder and, notwithstanding anything herein to the contrary, none
of the restrictions in this Section 3 (c) shall extend to any additional fibers
that Zayo owns on that Segment Group. For example, if User has [***] Initial
Fibers and [***] ROFR Fibers on a given Segment Group, but Zayo owns a [***]
count fiber optic cable on that Segment Group, Zayo may without any
restrictions, lease, license, sell, transfer, use or light up to [***] fibers on
that Segment Group.
(ii) Zayo agrees that during the RFR Term, it will not lease, license, sell or
otherwise transfer the ROFR Fibers until it complies with this Section 3(c)(ii).
During the RFR Term, Zayo may notify User in the event that Zayo receives a bona
fide opportunity from an unaffiliated third party that it is ready, willing and
able to lease, license or purchase fibers in any Segment(s) in a T Market
containing a balance of ROFR Fibers (“ROFR Notice”). If the ROFR Notice includes
more than sixty route miles, Zayo shall provide User with reasonable supporting
documentation that confirms the bona fide opportunity, provided that Zayo has
the right to redact the name of the third party and any pricing information. If
User desires to exercise its right of first refusal for the Segment(s) specified
in the ROFR Notice, User will notify Zayo within [***] days of receipt of the
ROFR Notice, and such notice will include the number of ROFR Fibers User is
requesting (in no event less than [***] fibers in all Segments identified in the
ROFR Notice) and the Parties will use commercially reasonable efforts to prepare
and execute a Service Order within [***] days thereafter subject to any
additional time that may be required to resolve issues the Parties are
diligently working to resolve. Upon execution of a Service Order, Zayo will
promptly deliver the

requested ROFR Fibers in accordance with the testing and acceptance provisions
set forth in this Agreement, the requested ROFR Fibers will become User Dark
Fiber hereunder, and any remaining ROFR Fibers not leased by User in the
Segment(s) specified in the ROFR Notice shall no longer be available to User. If
User does not exercise its right of first refusal for the dark fibers specified
in an ROFR Notice within [***] days of receipt of the ROFR Notice and/or User
earlier notifies Zayo that it desires to release the dark fibers specified in
the ROFR Notice, then the amount of ROFR Fibers in the applicable Segments
specified in the ROFR Notice will be reduced by the lesser of (i) amount of
[***], or (ii) the amount of [***] in the applicable Segments specified in the
ROFR Notice.
(iii) During the RFR Term, Zayo will not light the ROFR Fibers for its own use
or utilize the ROFR fibers to provide lit services until it complies with this
Section 3(c)(iii). If Zayo wishes to utilize any ROFR Fibers up to a maximum of
[***] ([***]) dark fibers in any Segment(s) to provide lit services to Zayo’s
customers or to light for its own use, it must notify User (“Lit Notice”). If
User desires to exercise its right of first refusal for the Segment(s) specified
in the Lit Notice, User will notify Zayo within [***] days of receipt of the Lit
Notice, which notice includes the number of ROFR Fibers requested (in no event
less than [***] fibers in any Segment) and the Parties will use commercially
reasonable efforts to prepare and execute a Service Order within [***] days
thereafter subject to any additional time that may be required to resolve issues
the Parties are diligently working to resolve. Upon execution of a Service
Order, Zayo will promptly deliver the requested ROFR Fibers in accordance with
the testing and acceptance provisions set forth in this Agreement, the requested
ROFR Fibers will become User Dark Fiber hereunder, and the amount of any
remaining ROFR Fibers in the applicable Segments specified in the Lit Notice
shall be reduced by the number of dark fibers leased by User. If User does not
exercise its right of first refusal for the dark fibers specified in a Lit
Notice within ten days of receipt of the Lit Notice and/or earlier notifies Zayo
that it desires to release the dark fibers specified in the Lit Notice, Zayo may
utilize the dark fibers specified in the Lit Notice for the purpose of providing
lit services and/or light the ROFR Fibers for its own use and User’s right of
first refusal for the Segment(s) specified in the Lit Notice shall be reduced by
the number of dark fibers specified in the Lit Notice which shall not exceed
[***] ([***]) fibers. Zayo may not submit a Lit Notice for a given Segment Group
in a T Market more than [***] in any rolling [***] period.
d.    The Lease Fee for the Option Fibers and ROFR Fibers shall be determined in
accordance with Section 7d below. In addition, User shall reimburse Zayo [***]
for all required splicing, Splicing Reconfigurations and Demarcation Point
connections for each Option Fiber Service Order and ROFR Fiber Service Order.
There shall be no additional [***] for the Option Fibers or the ROFR Fibers. The
Terms of each Service Order for the Option Fiber and ROFR Fiber shall, in User’s
sole discretion, be either [***] years from the date of acceptance or
coterminous with the Initial Fiber for the applicable metropolitan city. User
shall identify the applicable term in its notice to Zayo when requesting Option
Fibers or when it exercises its right of first refusal. For Option Fibers or
ROFR Fibers with a [***] year term, User may, by notifying Zayo at any time
prior to December 31, [***], convert the Term of all, but not less than all,
such Option Fibers or ROFR Fibers with a [***] year Term to a Term that is
coterminous with the Initial Fiber for the

Exchange Commission together with such request for confidential treatment.

applicable metropolitan city (“Conversion Option”). The Term of any Option
Fibers or ROFR Fibers ordered by User after the Conversion Option shall be
coterminous with the Initial Fiber for the applicable metropolitan city. In the
event User does not exercise the Conversion Option, all Option Fibers and ROFR
Fibers with a [***] year Term shall automatically terminate upon expiration of
the relevant initial [***] year Term and shall not be eligible for any renewal
Term.
e.    In the event Zayo fails to provide any Option Fibers or ROFR Fibers to
User within the timelines specified below and such failure continues for an
additional [***] days following written notice by Customer of Zayo’s failure to
meet a delivery timeline (“Late Delivery Notice”), the monthly Lease Fee for the
affected Segments under this 5th Amendment (which includes any Segments where
Zayo delivered the requested Option Fibers and/or ROFR Fibers but User’s use of
such Option Fibers and/or ROFR Fibers is materially restricted by Zayo’s failure
to deliver Option Fibers and/or ROFR Fibers on another Segment) shall be reduced
by [***] percent ([***]%) from the date of the missed delivery date for the
applicable Option Fibers and/or ROFR Fibers until such time as Zayo has provided
and User has in good faith Accepted the applicable Option Fibers and/or ROFR
Fibers. Additionally, if Zayo fails to timely provide User the applicable Option
Fibers and/or ROFR Fibers within [***] days following the Late Delivery Notice,
User may, at its option (subject to the terms and provisions of the Underlying
Rights), cure or correct such failure by constructing fibers equivalent to the
applicable Option Fibers and/or ROFR Fibers in the Segments that lack Option
Fibers and/or ROFR Fibers, utilizing a Zayo approved contractor, and Zayo shall
reimburse User for [***]. If User exercises its option to cure such failure as
provided immediately above, upon completion of such cure, the fibers constructed
shall be owned by Zayo, the number of Option Fibers or ROFR Fibers originally
requested by User in that Segment Group shall become User Dark Fibers under this
Agreement at the applicable Lease Fees specified in Section 7 and the [***]
percent ([***]%) reduction in Lease Fees shall cease. Notwithstanding the
foregoing, and subject to Section 3f below, if Zayo’s failure to timely deliver
Option Fibers or ROFR Fibers to User is caused by an Event of Force Majeure
(including but not limited to any government moratoriums and permitting delays
not caused by Zayo’s actions or omissions), Zayo’s obligation to deliver such
Option Fibers or ROFR Fibers to User shall be extended for the duration of the
Event of Force Majeure.
Zayo shall, within 30 days following the date that a Service Order is fully
executed for any Option Fibers or ROFR Fibers, apply for all permits, licenses
or other permissions required to access or complete any required splicing
(collectively “Access Permits”). Zayo shall provide an acceptable Completion
Notice for any Option Fibers or ROFR Fibers to User within the following
timelines following receipt of the relevant Access Permits and based on the
Route Miles associated with the Option Fibers or ROFR Fibers as further
identified below:

f.    In the event Zayo fails to provide an acceptable Completion Notice for any
Option Fibers or ROFR Fibers to User within the timelines specified in Section 3
(e) above, and such failure to provide is due to an Event of Force Majeure as
specified in Section 3 e above, but Zayo is able to provide dark fiber or lit
services that meets Zayo’s fiber specifications for other customers along the
same fiber path and cable impacted by the Event of Force Majeure, then the Event
of Force Majeure shall not excuse Zayo’s obligations to provide the applicable
Option Fibers or ROFR Fibers and the provisions of Section 3e above shall apply.
Notwithstanding the above, Zayo’s inability to provide the fiber due to its
inability to access the fiber or any related access points caused by an Event of
Force Majeure through no fault of Zayo (including but not limited to any
government moratoriums and permitting delays not directly caused by Zayo’s
negligent actions or omissions) shall not trigger the penalties set forth in
Section 3.e regardless of the provisioning of dark fiber or lit services to
other Zayo customers.
g.     User agrees to Lease the minimum amount of Option Fibers and/or ROFR
Fibers as identified below, in accordance with the terms of this Section 3 by
each milestone date as specified in the tables below (cumulatively “Purchase
Commitment”):

If User fails to lease the required amount of Option Fibers and/or ROFR Fibers
by a Milestone Date, Zayo may begin billing User the Lease Fee each month for
the difference between the total combined Option Fibers and ROFR Fibers leased
by that Milestone Date and the applicable Purchase Commitment amount at the
pricing contained in Section 7d (“Shortfall Charge”) until such time that User
has met its Purchase Commitment. User’s failure to meet the Purchase Commitment
by the applicable Milestone Date shall be reduced proportionately to the extent
that any such failure is caused by Zayo’s failure to provide ordered Segments in
accordance with the timelines set forth in Section 3(e) above.
   
FOR EXAMPLE: IF USER HAS LEASED A TOTAL OF [***] FIBER MILES OF OPTION FIBERS
AND ROFR FIBERS BETWEEN THE 5TH AMENDMENT EFFECTIVE DATE AND THE [***] MONTH
MILESTONE DATE, BEGINNING ON THE [***] MONTH FROM THE 5TH AMENDMENT EFFECTIVE
DATE THE SHORTFALL CHARGE PAYABLE BY USER SHALL EQUAL TO $[***] ($[***] X 1,000
FIBER MILES).

4.    Added Route Fibers.     User shall have an option to acquire additional
User Dark Fibers for Eligible Segment(s), as defined below, in Zayo’s System
located in each of the metropolitan cities identified in Exhibit B (collectively
“Added Route Fibers”) as follows:
a.    For the initial [***] ([***]) month period beginning on the Amendment
Effective Date, User shall have the right to request a Lease in additional User
Dark Fibers for potential Eligible Segment(s) located within the metropolitan
cities identified in Exhibit B. In the event that User desires to exercise this
option on one or more occasions during the [***] ([***]) month period specified
above, User will provide a written request to Zayo specifying the proposed User
Route where User desires to lease additional User Dark Fibers (“Added Route
Fiber Notice”). Within [***] days of receipt of an Added Route Fiber Notice,
Zayo will inform User in writing which portions of the requested User Route and
User Dark Fibers specified in the Added Route Fiber Notice are Eligible
Segment(s) (where eligibility qualifications are further described in Section 4
c. below) and identify total User Dark Fiber net availability, if any, within
such Eligible Segments up to a maximum of [***] fibers

(“Eligible Segment Notice”). User shall have [***] days after receipt of the
Eligible Segment Notice to notify Zayo of its desire to Lease a specified amount
of User Dark Fibers contained in the Eligible Segment Notice in one or more of
the Eligible Segment(s) specified in the Added Route Fiber Notice (“Added
Eligible Segment Notice”). Thereafter, the Parties will amend the Service Order
for the applicable metropolitan city to add the User Dark Fibers specified in
the Added Eligible Segment Notice at the same rates and terms applicable to the
Initial Fibers.
b.    The Term of a Service Order amended by Added Route Fibers will commence in
accordance with its terms irrespective of the delivery of the Added Route Fibers
(i.e. acceptance of the Added Route Fibers will not delay billing of the Service
Order), and the applicable Lease and Maintenance Fee will increase
proportionately as the Added Route Fibers are accepted in accordance with the
Agreement.
c.    “Eligible Segment” is a Segment in Zayo’s System that contains [***]
([***]) or more unused dark fibers as of the date of Zayo’s receipt of the
applicable Added Route Fiber Notice, and is not committed to another purpose,
subject to a pending transaction with another party, or subject to additional
other considerations including, but not limited to, fiber demand, reserved
fiber, physical constraints, and additional construction requirements.
Additionally, the total Route Miles in the Eligible Segments leased by Zayo to
User shall be no more than a maximum of [***] ([***]) Route Miles.
5.    Laterals. User may request Lateral Spurs to existing Zayo on-net buildings
from the Initial Fibers, ROFR Fibers and the Option Fibers of each Segment. Upon
receipt of the request for such Lateral Spurs, Zayo shall review availability
and either accept or reject the request, in Zayo’s sole discretion. In the event
Zayo accepts the request, the Parties shall mutually agree to and execute a
Service Order. For the avoidance of doubt, the User Requirements provision as
further described in the Service Order template shall always be a provision in
any Lateral Spur Service Orders.
6.    Future Splicing Reconfigurations. Notwithstanding anything to the contrary
contained in the Agreement or any amendment, addendum, Service Order or other
document associated with or relating to the Agreement, both Parties agree that,
with respect to the User Dark Fibers in Service Orders and Metro Service Orders
under this 5th Amendment, User shall have the same connection rights as set
forth under Section 9 of the Agreement. Subject to the provisions of Section 9
of the Agreement, User may request that Zayo connect and tie in [***] with the
User Dark Fibers provided in the Service Orders under this 5th Amendment.
In addition, with respect to the User Dark Fibers in Service Orders under this
5th Amendment, the Parties acknowledge that Splicing Reconfigurations, solely at
existing Connecting Points and Zayo’s splice enclosures containing User Dark
Fiber of said Service Order, may be requested by User and hereby agree to the
following intervals and charges:
a.Zayo will accept requests for Splicing Reconfigurations within [***] ([***])
days of receipt and, if no material Zayo facility modifications are required
necessitating a revision to the Splicing Reconfiguration, will complete such
splicing within [***] ([***])

business days of such request. For purposes of this Section 6, each “Splicing
Reconfiguration” shall mean a change of splicing within a single existing
Connecting Point.
b.If a revision to the initial requested Splicing Reconfiguration is deemed
necessary by Zayo (for reasons including, but not limited to, physical
constraints, access requirements or new Zayo equipment or other work required to
complete the requested Splicing Reconfiguration), Zayo will revise such request
within [***] ([***]) days of receipt and will further notify User of the
additional Costs that User must pay Zayo to complete the requested Splicing
Reconfiguration. User shall review such Costs and notify Zayo of its acceptance
or rejection of such additional Costs. If User agrees to pay such additional
Costs, Zayo will complete such work within [***] ([***]) business days of User’s
written acceptance of the revised Splicing Reconfiguration.
c.In the event Zayo is not reasonably able to complete the Splicing
Reconfiguration as specified in Sections 6 a. and b. above within [***] ([***])
days, then Zayo will use good faith efforts to complete such request in a
commercially reasonable expedited and continuous timeframe.
d.Zayo will invoice User Splicing Reconfigurations at the rates specified in
Exhibit I and such invoice shall be payable in accordance with the Agreement.
e.User acknowledges that the above delivery intervals may be impacted by
circumstances beyond the control of Zayo including, but not limited to, permit
processing delays and moratoriums. In such event, Zayo will not be in breach of
the above intervals so long as Zayo is making continuous commercially reasonable
good faith efforts to obtain such permits or otherwise move forward with the
permitting and splicing process.

7.    Pricing. Upon execution of this 5th Amendment, the Parties shall use
commercially reasonable efforts to prepare and execute Service Orders for the
Initial Fibers described in Exhibit B within sixty (60) days. The pricing set
forth in this Section 7 shall apply only to the Service Orders described
immediately above (together with the Option Fibers and ROFR Fibers and Added
Route Fibers ordered in accordance with Section 4 of this 5th Amendment) for
those metropolitan markets, route segments within each market, and related route
mileage and fiber counts specifically identified in Exhibit B.
a.    The Lease Fee for Initial Fibers, Option Fibers and Added Route Fibers
shall be a monthly recurring rate of $[***]/per fiber mile/per month. “Fiber
mile” as used in this 5th Amendment shall mean, with respect to any applicable
Service Order, the product of Route Miles multiplied by the User Dark Fiber
count within said route. “Route Miles” as used in this 5th Amendment shall mean,
with respect to any applicable Service Order, the Parties' determination of
total linear miles for the User Route, as agreed to by the Parties and set forth
in a Service Order (which shall be fixed and not subject to change during the
Term).

imposed upon the Zayo System following the Acceptance Date, or any part thereof,
or upon the User Dark Fibers, or any part thereof, by any state or local
government or other authority (collectively “Grantor”), and that are based on
the amount of rights-of-way being used and are not based on Zayo’s revenues or

in Sections 10(c)(i) and 10 (c)(ii) below, the pricing and committed term,
including renewals, shall be the same as the applicable pricing and remaining
committed term as in effect for the applicable Metro Dark Fiber Agreement
immediately prior to execution of the Metro Service Order. The Parties shall
each use commercially reasonable efforts to enter into Metro Service Orders for
the Metro Dark Fiber Agreements included in the Migration Option by December 15,
2013. Upon execution of the Metro Service Orders, the User Dark Fibers and
associated facilities specified in such Metro Services Orders shall be provided
in accordance with the Agreement and the corresponding Metro Dark Fiber
Agreements shall immediately terminate. For the avoidance of doubt, none of the
Metro Dark Fiber Agreements are eligible for the Option Fibers or ROFR Fibers as
further described in Section 3 of this 5th Amendment.
i.    For the Metro Dark Fiber Agreements with [***] years or less remaining in

or not participate in such Involuntary Relocation as specified in Section 11.4.
Zayo’s invoicing for Involuntary Relocations will be in accordance with Section
11.4 of the Agreement and shall describe the scope of work, Cost of work (upon
request Zayo will provide supporting documentation of all such Costs), and
detail all calculations used in obtaining the User’s share of the Costs. For the
avoidance of doubt, Section 11.3 as amended herein, shall apply to all Service
Orders subject to the Agreement.
12.    Portability and Zayo Construction Option.

a. The Parties previously entered into Service Order 2 – San Francisco – San
Jose, Zayo Service Order Number 373533 (“Service Order 2”). Effective on the
Acceptance Date of the last Segment in the Service Order for the Initial Fibers
located in the San Jose Market, Service Order 2 shall be repriced in accordance
with the provisions of Section 7 (a), (b) and (c).

b. User may, within [***] from the 5th Amendment Effective Date (“SLROFR
Period”) desire to construct or otherwise obtain from a third party up to [***]
dark fibers along the route specified in Exhibit J (“Salt Lake Route”). For the
SLROFR Period, User shall grant Zayo a right of first refusal (“SLROFR”) to
provide the Salt Lake Route for User at the lesser of Zayo’s Costs or $[***]
(“SLR NRC”). User agrees that during the SLROFR Period, it will not construct or
obtain from a third party the Salt Lake Route unless it complies with this
Section 12b. During the SLROFR Period, User will notify Zayo in the event that
User desires to construct or obtain from a third party the Salt Lake Route
(“SLROFR Notice”). If Zayo desires to exercise its SLROFR, Zayo will notify User
within [***] days of receipt of the SLROFR Notice of its desire to provide to
User the Salt Lake Route within [***] days for the SLR NRC. If Zayo exercises
the SLROFR, the Parties will enter into a Service Order with a Committed
Delivery Date of [***] days from the SLROFR Notice. Upon completion of the Salt
Lake Route, the applicable dark fibers in the Salt Lake Route shall become User
Dark Fibers under the Agreement with the term and renewal terms specified in
Section 9a and a monthly recurring Maintenance Fee in accordance with Section 8c
provided that, in consideration of the SLR NRC, no Lease Fees shall apply to
such Salt Lake Route for the duration of its Term. If Zayo does not exercise its
right of first refusal within [***] days of receipt of the SLROFR Notice, Zayo’s
SFROFR expires and User may construct or obtain from a third party the Salt Lake
Route without utilizing Zayo.
 
13.    Fiber Specifications and Performance. All User Dark Fibers provided under
this 5th Amendment will perform according to the fiber specifications as further
described in the “Testing and Acceptance of User Dark Fibers” section of the

of the Agreement, and shall meet or exceed all such specifications for [***] of
the respective Service Order.
14.    Deliverables. Within ninety (90) days of the Acceptance Date for a given
Service Order, Zayo will provide User with a CD ROM to include the associated
OSPInSight databases for all User Dark Fibers hereunder. The OSPInSight database
files will include all associated MapInfo database layers needed for a complete
and working OSPInSight database, including but not limited to; Segment
numbering, manhole locations and numbers, splice locations, fiber assignments,
and fiber counts. The Parties mutually acknowledge that situations may occur

hereunder. Any such set-off in good faith of any future Lease Fee shall not
result in a breach of this Agreement or any related agreement provided that the
Zayo shall have the right to recover any future Lease Fees that were improperly
set-off. Zayo acknowledges and agrees that User shall have the right to setoff
the amount of the Non-Performed Obligations notwithstanding the commencement any
insolvency proceeding, relief under Title 11 of the United States Code or the
application of the automatic stay contained in 11 U.S.C. § 362.”
17.    Section 9.1 of the Agreement. The first sentence of Section 9.1 of the
Agreement is hereby deleted in its entirety and replaced with the following:
