      Amendment No. 79 (NE)
SOW:
  o No
 
  þ Yes

6.1   Software Development Work

The work necessary to incorporate the Change Order(s) set forth in Section 6.2
below into the NPAC/SMS Software in accordance with the project schedule set
forth in Article 8 below shall be referred to collectively as the “Software
Development Work.” The Software Development Work associated with the Change
Order(s) includes the following activities: requirements definition; system
design; coding and unit testing; system integration testing, system and
regression testing; program management; quality assurance; configuration control
and documentation management, as well as application support, customer support,
and system administration support.

6.2   Change Order

The NPAC/SMS Software shall incorporate and provide the functionality of the
following change order (“Change Order”) issued by the North American Numbering
Council (NANC).
NANC 442 — Pseudo LRN
Change Order NANC 442 mitigates the impact of NPAC record growth on service
provider LSMSs and downstream systems caused when other service providers’
internal network management activities result in the creation of SV and pooled
block records for telephone numbers that are neither ported nor pooled.
The change order accomplishes this by accommodating use cases where an LRN is
not required to route voice traffic to a telephone number, but the provider
serving the telephone number requires that an NPAC SV or pooled block record be
created in order to display other information associated with the number.
Examples of such other information are DPC addresses different from those
associated with non-ported numbers within the same NPA-NXX, first and/or last
altSPID values, URIs, and information populated in the EULT, EULV, or Billing ID
fields. These records may be created for any number of reasons, such as to
indicate the subtending service provider or reseller to which the network
service provider has allocated the telephone number (for pre-port information
purposes or to facilitate subpoena delivery) or to manage future network
migration activities that must keep pace with porting and pooling updates.
The change order accommodates these use cases by allowing SV and pooled block
records to be established without requiring that all LSMSs receive broadcasts of
these records. This is accomplished by the creation of records with 000-000-0000
entered as the LRN value. This pseudo-LRN value indicates to the NPAC that the
record thus created is to be broadcast only to those LSMSs that have indicated
in their NPAC profiles a desire to receive pseudo-LRN SV or pooled block
broadcasts for records created by this SPID.
The ability to receive or create pseudo LRN records is optional. This change
order does not impact SOA and/or LSMS systems that do not make use of the
pseudo-LRN capability. By allowing service providers to ignore pseudo-LRN
records or, if opted-in to the pseudo-LRN capability, to limit broadcasts to
those records created by the SPIDs for which pseudo-LRN records are desired, the
LSMS operators are able to manage their LSMS record storage requirements.
Further, a service provider that has not elected to participate in the
pseudo-LRN capability still may query the NPAC for information contained in a
pseudo-LRN record, either

      Amendment No. 79 (NE)
SOW:
  o No
 
  þ Yes

through its LTI or by contacting the NPAC Help Desk, and thus may benefit from
the capability without electing to participate in it.

6.3   Backward Compatibility

The Enhancement shall be backward-compatible, such that populating and
broadcasting SV data containing Pseudo-LRN records will not be visible to User
systems that have not performed the steps necessary to use the functionality
afforded by the Enhancement. Because the Enhancement shall be
backward-compatible, its mere deployment in the NPAC/SMS will not result in any
obligatory changes to SOA or LSMS systems for Users not opting to use their SOA
or LSMS for the functionality afforded by the Enhancement.

6.4   Opt-In

A User wishing to modify its SOA system to populate Pseudo-LRN records in the
NPAC or to modify its LSMS system to receive broadcasts from the NPAC of any
Service Provider’s Pseudo-LRN data shall be required to complete certification
procedures, as described in section 6.6, and to update its NPAC profile.
Nothing in this section shall be interpreted to modify a User’s ability to
create, modify, delete, or view User Data containing a Pseudo-LRN record. All
Users may continue using Low-Tech Interface (LTI), Mass Update Mass Port (MUMP),
or NPAC Help Desk to create, modify, delete or to view User Data containing a
Pseudo-LRN record, including even those Users that do not update their SOA or
LSMS systems to make use of the Enhancement.

6.5   No Impairment

The deployment of the Enhancement in the NPAC/SMS to include the functionality
of Change Order 442 and the population of Pseudo LRN in SVs and pooled blocks
will at all times be subject to all performance measurements required under the
Master Agreement, including all Amendments and Statements of Work issued
thereunder, including, without limitation, the Service Level Requirements set
forth in Exhibit G to the Master Agreement. Contractor hereby commits to bear
the costs of any future upgrades necessary to meet the Service Level
Requirements set forth in Exhibit G of the Master Agreement in the event
NPAC/SMS performance appears likely to be adversely impacted by TN Porting
Events attributable to the Enhancement.

6.6   Certification Testing

Contractor and Customer Project Executives shall establish performance testing
requirements for each User opting to use its SOA to populate Pseudo-LRN data or
to use its LSMS to receive broadcasts of Pseudo-LRN data, in order to assure
that the User’s connecting SOA and LSMS systems can meet any increased TN
Porting Event volumes associated with Pseudo LRN population and broadcast.

  þ Yes

6.7   Large Port Notifications

The planned creation (activation), modification or deletion of large quantities
of SV records with Pseudo-LRN values shall be reported to Users in the same
manner and under the same circumstances as the planned creation (activation),
modification or deletion of large quantities of SV records having conventional
LRN values.

6.8   Relationship of Subscription Version with a Pseudo LRN to Master Agreement

Nothing herein is intended to prevent the creation, modification or deletion of
an SV into which a Pseudo LRN value has been populated into the LRN field from
being deemed a TN Porting Event, so long as such creation, modification or
deletion of an SV meets the criteria set forth in the Master Agreement for a TN
Porting Event, including the definition set forth in Exhibit E to the Master
Agreement.
An SV containing a Pseudo LRN shall be considered an SV in the NPAC/SMS for all
purposes allowed under the Master Agreement. By way of clarification, the
immediately foregoing shall mean that nothing herein is intended to prevent an
SV into which a Pseudo LRN has been entered from being measured for purposes of
determining the National TN Inventory under Section 35.5(a) of the Master
Agreement for any purpose, including, but not limited to, determining whether a
TN Inventory Adjustment Event under Section 35.5(a) of the Master Agreement has
taken place or determining whether a National Ceiling Threshold Event taken
place under Section 35.7 of the Master Agreement.

6.9   Monthly Reporting

Beginning the first (1st) month after Acceptance of the Enhancement in all seven
(7) Service Areas corresponding to the seven (7) Subscribing Customers set forth
in Article 2 above, Contractor shall deliver to Customer a report consisting of
the total number of TN Porting Events, distinguished by LNP Type, occurring in
the previous calendar month in the Service Area for SVs containing a Pseudo-LRN
value.

7.   OUT OF SCOPE SERVICES

This SOW contains the agreed upon terms and conditions that shall govern
Contractor’s performance of the Additional Services described herein. The
Additional Services provided for in this SOW shall not be interpreted, implied,
or assumed to include any other service(s), including additional or changed
services, not specifically described in Article 6 above. Any and all requested
or required services or change orders (hereinafter “Out of Scope Services”) may
be provided in accordance with Article 13 of the Master Agreement.

10.   CREDITS

  (a)   National Enhancement Credit

Upon Customer’s Acceptance of the Enhancement on behalf of all the Subscribing
Customers corresponding with the seven (7) Service Areas set forth in Article 2,
and provided that the functionality introduced by NANC Change Order 442, namely
the ability to create, modify, and delete SVs and blocks with a Pseudo-LRN and
for the NPAC/SMS to selectively broadcast such SVs and blocks to participating
LSMSs, is available in all seven (7) United States Service Areas administered by
Contractor under the several Master Agreements, an aggregate credit (the
“National Enhancement Credit”) equal to Five Hundred Thousand Dollars ($500,000)
shall be allocated among a number of Service Areas equal to seven (7)
(corresponding to the number of Subscribing Customers as of the SOW Effective
Date set forth in Article 2 above) in the same manner as the Net National
Monthly Aggregate Porting Charge is applied in accordance with Section 35.1 of
the Master Agreement. The National Enhancement Credit shall be reflected with
the first invoices issued to Allocated Payors in the Service Area, pursuant to
Section 35.8 of the Master Agreement, in the month immediately following
Customer’s Acceptance of the Enhancement.

  (b)   National Quarterly Pseudo LRN Credit

  (i)   Measurement, Calculation and Annual Cap

Provided the Enhancement is Accepted in all seven (7) Service Areas
corresponding to the seven (7) Subscribing Customers set forth in Article 2
above, Contractor shall for each calendar quarter (each a “Measuring Quarter”),
beginning with the Measuring Quarter coinciding with the SOW Effective Date and
ending with the last calendar quarter of calendar year 2012, measure the total
number of active Subscription Versions (SVs) in all seven (7) United States
Service Areas in the NPAC/SMS administered by Contractor under the several
Master Agreements, wherein the value “000-000-0000” (the “Pseudo LRN”) is
entered as the LRN value in accordance with NANC Change Order 442 (such total
number of SVs, the “National Quarterly Pseudo LRN Inventory”). Contractor shall
undertake such measurement promptly after the end of the applicable Measuring
Quarter. Contractor shall then multiply the National Quarterly Pseudo LRN
Inventory by the Pseudo LRN Credit set forth immediately below for each
applicable calendar year (such product resulting in the “National Quarterly
Pseudo LRN Credit”).

          APPLICABLE       ANNUAL CAP OF THE CALENDAR   PSEUDO LRN   NATIONAL
QUARTERLY YEAR   CREDIT   PSEUDO LRN CREDIT 2010   $0.0083   $1,000,000 2011

CONFIDENTIAL

 

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

 

      Amendment No. 79 (NE)
SOW:
  o No
 
  þ Yes

The calculation of the National Quarterly Pseudo LRN Credit is associated only
with SVs containing a Pseudo LRN value, and is not intended to be associated
with SVs not containing a Pseudo LRN value in any NPAC.
The aggregate amount of the National Quarterly Pseudo LRN Credit that may be
calculated pursuant to Section 10(a)(i) above for each of calendar years 2010,
2011 and 2012 shall not exceed the amount of the Annual Cap of the National
Quarterly Pseudo LRN Credit set forth in the table above in this
Section 10(a)(i) for each Applicable Calendar Year (i.e., 2010, 2011 and 2012),
and no amount in excess of the Annual Cap of the National Quarterly Pseudo LRN
Credit for the Applicable Calendar pursuant to this Section 10(a)(i) shall be
carried forward or applied in any other Applicable Calendar Year. For example,
if the first Measuring Quarter for calendar year 2010 coincides with the last
calendar quarter for such year, and as a result of Contractor’s measurement on
the first day of January, 2011 the total number of SVs as of the last day of
December, 2010 results in the calculation of a National Quarterly Pseudo LRN
Credit equal to $2,000,000, then the aggregate amount the National Quarterly
Pseudo LRN Credit that will be allocated to Allocated Payors in all Service
Areas for three Billing Cycles beginning with the December, 2010 invoices
(mailed in January, 2011) will equal and not exceed $1,000,000.

  (ii)   Timing and Annual Cap

The National Quarterly Pseudo LRN Credit shall be allocated among a number of
Service Areas equal to seven (7) (corresponding to the number of Subscribing
Customers as of the SOW Effective Date set forth in Article 2 above) in the same
manner as the Net National Monthly Aggregate Porting Charge is allocated to the
Service Areas in accordance with Section 35.1 of the Master Agreement. The
National Quarterly Pseudo LRN Credit shall be ratably reflected, pursuant to
Section 35.8 of the Master Agreement, on invoices issued to Allocated Payors in
the Service Area over the next three (3) Billing Cycles beginning with the first
invoices issued to Allocated Payors in the Service Area associated with the last
month of the Measuring Quarter. For example, if as a result of Contractor’s
measurement on the first day of April the total number of SVs as of the last day
of March results in the calculation of a National Quarterly Pseudo LRN Credit,
then one-third (1/3) of the Allocated Payor’s share of the National Quarterly
Pseudo LRN Credit will appear in each of the invoices to Allocated Payors for
March (mailed in April), April (mailed in May), and May (mailed in June).

  (c)   Division, Apportioning, and Invoicing

Each Allocated Payor’s share of the Service Area’s share of the National
Enhancement Credit and the National Quarterly Pseudo LRN Credit (the “SOW 79
Credits”) shall be issued in the same manner as the division, apportioning and
invoicing of Allocated Charges is determined under SOW11 and in accordance with
the Cost Recovery Order, pursuant to Section 6.6(c) of the Master Agreement, and
shall be issued solely as a reduction against charges allocable or chargeable to
Allocated Payors on invoices issued by Contractor.
If for any Allocated Payor the amount of the SOW 79 Credits issued on an invoice
does not apply in full such Allocated Payor’s share of the SOW 79 Credits, then
the remaining share of
Page 9
CONFIDENTIAL

 

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

 

      Amendment No. 79 (NE)
SOW:
  o No
 
  þ Yes

such unapplied SOW 79 Credits allocable to that Allocated Payor shall be issued
again on the next monthly invoice, and any subsequent invoices as necessary, of
such Allocated Payor in the amount of the lesser of (i) the full amount of the
remaining unapplied amount of the SOW 79 Credits allocable to that Allocated
Payor or (ii) the full amount of all charges allocable or chargeable to such
Allocated Payor, until the share of the SOW 79 Credits allocable to that
Allocated Payor is fully issued.
In no event shall any amount of a share of the SOW 79 Credits that is not fully
issued result in a monetary payment of any kind, including, without limitation,
as a result of the expiration or termination of any Statement of Work or the
Master Agreement, other than the application of such SOW 79 Credits as a
reduction against charges allocable or chargeable to Allocated Payors on
invoices issued by Contractor.

  (d)   Invoice Itemization

The invoices in which each Allocated Payor’s share of the SOW 79 Credits is
first issued shall clearly identify and itemize the amount of the SOW 79
Credits, including the amount of the National Quarterly Pseudo LRN Inventory and
the share of the National Quarterly Pseudo LRN Credit allocable to the Allocated
Payor that is issued on an invoice. Any amount of an Allocated Payor’s share of
the SOW 79 Credits that remains after issuance on that invoice shall be
aggregated with and added to amounts of the Allocated Payor’s share of such SOW
79 Credits remaining for application on future invoices. Any such amounts the
Allocated Payor’s share of the SOW 79 Credits issued on subsequent invoices
shall be clearly identified on such invoice and any subsequent invoices.

  (e)   Preservation of Rights of Setoff

Allocated Payors retain their right of set-off against all charges allocable to
Allocated Payors on invoices issued by Contractor, including for Contractor’s
failure to properly and accurately compute, issue and apply the Allocated
Payor’s share of the SOW 79 Credits.

  (f)   Condition

The division, apportionment and invoicing of the SOW 79 Credits is conditioned
upon the continued availability of the functionality introduced by NANC Change
Order 442. If such functionality is not available for any reason (other than a
Neustar act or omission) in any calendar month for which the National Quarterly
Pseudo LRN Credit (in whole or in part) were available on invoices issued to
Allocated Payors to reduce charges allocable or chargeable to Allocated Payors
on invoices issued by Contractor, then the SOW 79 Credits shall be suspended,
such that it shall not be available to reduce such charges in such invoice. By
way of clarification, and not limitation, the suspension of the SOW 79 Credits
shall not in any way affect the application in any calendar year of the Annual
Cap of the National Quarterly Pseudo LRN Credit under Section 10(b) above.
The SOW 79 Credits shall subsequently be available to Allocated Payors to reduce
charges allocable or chargeable to Allocated Payors on invoices issued by
Contractor only when the

functionality introduced by NANC Change Order 442, namely the ability to create,
modify, and delete SVs and blocks with a Pseudo-LRN and for the NPAC/SMS to
selectively broadcast such SVs and blocks to participating LSMSs, was available,
without interruption, in all United States Service Areas administered by
Contractor under the several Master Agreements for a full calendar month.

11.   Gateway Evaluation Process Waivers

The computation, division, apportioning, issuance, application, and invoicing of
any invoices setting forth an Allocated Payor’s share of a National Quarterly
Pseudo LRN Credit shall be auditable and included in determining “Reporting” for
purposes of Element No. 2, “Billing Timeliness” for purposes of Element No. 7a,
and “Billing Accuracy” for purposes of Element No. 7b of the Gateway Evaluation
Process as set forth in Article 32 of the Master Agreement only upon the third
(3rd) Billing Cycle after its sending; provided that Customer and Contractor
have issued an updated GEP Metrics Document as set forth in Article 32 of the
Master Agreement. All invoices setting forth an Allocated Payor’s share of the
National Quarterly Pseudo LRN Credit issued prior to the date of such Third
Billing Cycle shall be deemed satisfied for purposes of Element No. 2, timely
for purposes of Element No. 7a, and accurate for purposes of Element No. 7b of
the Gateway Evaluation Process. Nothing herein shall preclude Contractor from
issuing an adjustment credit to reflect the proper computation, division,
apportioning, issuance, application, and invoicing under any one or more
invoices issued thereafter in accordance with the updated GEP Metrics Document.
For purposes of the GEP, a copy of this SOW shall serve as a waiver letter
signed by Contractor and Customer.
