formal court or Board proceeding initiated by PRTC within the four (4) years preceding the Effective Date in which PRTC sought to recover sums owed for services provided by PRTC.

| | 6.3 | The Parties shall mutually agree to an assurance of payment that shall consist of either (a) an unconditional, irrevocable standby letter of credit naming PRTC as the beneficiary thereof and otherwise in form and substance reasonably satisfactory to PRTC from a financial institution duly authorized by the Puerto Rico Commissioner of Financial Institutions to do business in Puerto Rico; or (b) a bond payable to PRTC.  The letter of credit or bond shall be the greater of $100,000 oran amount equal to one (1) months anticipated charges (including, but not limited to, both recurring and non-recurring charges),as determined by using the average monthly, undisputed charges for the preceding twelve month period, for the
Services to be provided by PRTC to CSPR in connection with this Agreement.

All credits applied by PRTC will be applied to CSPRs
account within ten (10) business days after PRTC draws on the letter of credit or bond, as applicable, or by the next billing cycle thereafter, which ever occurs later.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 6.6 | Notwithstanding anything else set forth in this Agreement, if PRTC makes a request for assurance of payment in accordance with the terms of this Section 6, and CSPR does not provide the assurance of payment required by this Section within fifteen (15) days of CSPRs receipt of such request in writing, then PRTC shall, upon fifteen (15) days notice to CSPR and the Board, have no obligation thereafter to perform under this Agreement until such time as CSPR has provided PRTC with such assurance of payment. The Parties agree that this section does not waive or in any way prejudice any right CSPR may otherwise have to seek injunctive and/or other emergency relief.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 6.7 | The fact that a letter of credit or bond is requested by PRTC hereunder shall in no way relieve CSPR from compliance with the requirements of this Agreement (including, to the extent expressly incorporated by reference herein, the requirements of PRTCs Tariffs) as to advance payments and payment for Services, nor constitute a waiver or modification of the terms herein pertaining to the discontinuance of Services for nonpayment of any amounts payment of which is required by this Agreement.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 6.8 | Once CSPR is subject to the Bond or Letter of Requirements under 6.3 and subsequently demonstrates good payment history by paying undisputed amounts

by the Due Date for six (6) consecutive months, then CSPR shall be released from its obligations under Section 6.3 covering a Bond or Letter of Credit by the seventh month.  However, thereafter, CSPR will remain subject to the requirements of this Section 6 in the event that, subsequent to its release under this Section 6.8, CSPR again satisfies any of the conditions providing PRTC with the right to demand an assurance of payment under Section 6.3.

| | 6.9 | If, before PRTC has exercised the right to require and/or draw on an assurance of payment in accordance with this Section 6, CSPR has paid in full the amount outstanding giving rise to PRTCs exercise of such right pursuant to this Section 6, PRTC shall no longer be entitled to the exercise of such right based upon such previously outstanding amount.

In the event that a billing Party fails to correct a Billing Error in this time frame, the billed Party, thereafter, shall have no liability for the resulting erroneously billed amounts and may, in good faith, upon notice to the other Party, and without treating such amount as a Disputed Amount, deduct such erroneously billed amounts from its payment to the other Party.

| | ---- | -------------------------

| | 9.11 | For resale and unbundled network element services provided by PRTC to CSPR, the Parties acknowledge that PRTC has nine billing cycles per month while CSPR has one billing cycle per month.  The Parties agree that PRTC will make available CSPRs billing statements for each billing cycle within four (4) business days of PRTCs cycle date, unless the cycle date falls on a weekend or holiday, in which case the statement will be made available within four (4) business days from the next business day following the weekend or holiday (in either event, the day by which the statement is supposed to be made available shall be the Bill Date).  In addition, the Parties agree that the Due Date for all resale and unbundled network element services billed to CSPR by PRTC in a month shall, subject to Section 9.7,
be thirty (30) days after the date that all nine cycles of billing statements for a month have been made available to CSPR.  If, however, the last of the nine cycles for a month is not made available to CSPR within four (4) business days after the 22nd calendar day of such month (or, if the 22nd calendar day is not a business day, after the next calendar day which is a business day), the Due Date for such cycle shall, subject to Section 9.7, be sixty (60) days after the date that such cycle was made available to CSPR.  Moreover, in the event that any of the other eight cycles for a month is not made available to CSPR by the relevant Bill Date, the Due Date for payment of such late cycle shall be the Due Date as calculated in the third sentence of this Section 9.11, plus the number of days that the cycle was late.  For example, if a cycle other than the last billing cycle for a month is received two business days after the Bill Date for that cycle, the Due Date for that cycle shall be
two business days after the Due Date for the remaining cycles in that month.  For purposes of this Section 9.11, a statement that is made available to CSPR after 3:00 p.m. shall be considered to have been made available to CSPR on the next business day.
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 9.12 | In the event that PRTC fails to bill CSPR for a service under this Agreement more than ninety (90) days after such service is provided, CSPR will only be liable to pay fifty (50%) percent of such charges to PRTC, with such charges due sixty (60) days after CSPRs receipt of the PRTC invoice reflecting such charges.  Moreover, in the event that PRTC fails to bill CSPR for a service more than one hundred and fifty (150) days after such service is provided, CSPR shall have no liability for such charges and PRTC will issue a credit to CSPR in the amount of the charges upon notice by CSPR.
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 9.13 | PRTC shall apply to CSPRs invoices a monthly credit equal to the pro-rata cost of any PRTC service purchased by CSPR that is not properly functioning and provided that (1) CSPR has reported to PRTC as in need of repair; (2) the problem is caused on PRTCs side of the line; and (3) PRTC has completed the repair.  Such credit shall not apply if the problem is caused by CSPRs equipment or is on CSPRs side of the line.  Such credit shall be calculated daily from the date the needed repair was reported to the date the needed repair is completed.  Such credit shall also be calculated and applied by PRTC upon request from CSPR and shall include the PRTC USOC a detail of the service, the time waiting for repair and the amount of the credit by item.
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 9.14 | When an end user has changed from CSPR to either another service provider or to PRTC, CSPR will not be charged or responsible for any payment for wholesale services from PRTC after PRTC receives a change request order from another service provider or itself.  If the change request is received by PRTC after 3:00 p.m., the effective date of the change will be the next business day.

| | 9.15 | In the event that the Parties are unable to resolve a billing dispute through the processes outlined in this Section 9, either Party may seek to have any such billing dispute resolved using EDR as provided in Section 14.4 of the General Terms and Conditions of this Agreement.
| | ---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 9.16 | Upon written request, PRTC will respond to all written CSPR billing inquiries regarding resale local usage detail and USOC meanings within ten (10) business days and all other billing inquiries within twenty (20) business days.  In its response, PRTC will provide to CSPR in writing all clarifications, explanations, and supporting data reasonably required to respond to CSPRs billing inquiry.  The parties acknowledge that CSPR already receives (1) local usage detail for calls from UNE-P lines and (2) usage detail for resold intra-island toll, and PRTC shall have no additional obligation under this Section 9.16 to provide such detail for such calls.  In addition, if PRTC begins providing local usage detail for calls from resale lines, PRTC shall no longer be obligated to provide such detail under this Section
9.16.

During the period that the non-performing Party is unable to perform, the other Party shall also be excused from performance of its obligations to the extent such obligations are reciprocal to, or depend upon, the performance of the non-performing Party that has been prevented by the Force Majeure Event.  The non-performing Party shall use commercially reasonable efforts to avoid or remove the cause(s) of its non-performance and both Parties shall proceed to perform once the cause(s) are removed or cease.

Upon notification by PRTC to CSPR of possible fraud, CSPR shall retain responsibility to PRTC for payment of all charges on its Customers and accounts affected by the fraud, and PRTC shall bear no responsibility for, and shall have no obligation to investigate or make adjustments to CSPRs account in cases of, fraud by CSPRs Customers or other third parties, except to the extent that PRTCs negligence, willful misconduct, or breach of this Agreement contributed to and/or facilitated such fraud.

|5. | Reciprocal Compensation Arrangements Pursuant to Section 251(b)(5) of the Act
|-- | -----------------------------------------------------------------------------

| | 5.1 | Reciprocal Compensation.
| | --- | ------------------------

The Parties shall exchange Reciprocal Compensation Traffic at the technically feasible Point(s) of Interconnection on PRTCs network designated in accordance with the terms of this Agreement.  The Party originating Reciprocal Compensation Traffic shall compensate the terminating Party for the transport and termination of such traffic to its Customer in accordance with Section 251(b)(5) of the Act at the equal and symmetrical rates stated in the Pricing Attachment; it being understood and agreed that PRTC shall charge (and CSPR shall pay PRTC) the End Office Reciprocal Compensation rate set forth in the Pricing Attachment for Reciprocal Compensation Traffic CSPR physically delivers to a POI at the PRTC Wire Center in which the terminating PRTC End Office is located, and otherwise that PRTC shall charge (CSPR shall pay PRTC) the Tandem Reciprocal Compensation rate set forth in the Pricing
Attachment for Reciprocal Compensation Traffic CSPR delivers to PRTC; it also being understood and agreed that CSPR shall charge (and PRTC shall pay CSPR) the End Office Reciprocal Compensation rate set forth in the Pricing Attachment for Reciprocal Compensation Traffic PRTC delivers to CSPR, unless PRTC is required under Applicable Law to pay the Tandem Reciprocal Compensation rate set forth in the Pricing Attachment.  These rates are to be applied at the technically feasible Point(s) of Interconnection on PRTCs network at which the Parties interconnect, whether such traffic is delivered by PRTC for termination by CSPR, or delivered by CSPR for termination by PRTC.  No additional charges shall be assessed by the terminating Party for the transport and termination of such traffic from the technically feasible Point(s) of Interconnection on PRTCs network to its Customer; provided, however, for the avoidance of any doubt, CSPR shall also pay PRTC, at the rates set forth in
the Pricing Attachment, for any multiplexing, cross connects or other Collocation related Services that CSPR obtains from PRTC.  When such Reciprocal Compensation Traffic is delivered over the same Interconnection Trunks as Toll Traffic, any port, transport or other applicable access charges related to the delivery of Toll Traffic from the technically feasible Point(s) of Interconnection on PRTCs network to the terminating Partys Customer shall be prorated so as to apply only to the Toll Traffic.  The designation of traffic as Reciprocal Compensation Traffic for purposes of Reciprocal Compensation shall be based on the actual originating and terminating points of the complete end-to-end communication.

| | 5.2 | Traffic Not Subject to Reciprocal Compensation.
| | --- | -----------------------------------------------

| | 5.2.1 | Reciprocal Compensation shall not apply to interstate or intrastate Exchange Access (including, without limitation, Virtual Foreign Exchange Traffic (i.e., V/FX Traffic)), Information Access, or exchange services for Exchange Access or Information Access.
| | ----- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 5.2.2 | Reciprocal Compensation shall not apply to Internet Traffic.
| | ----- | ------------------------------------------------------------

| | ----- | -------------------------------------------------------------------------------------------------------------------------------------

| | 5.2.8 | Reciprocal Compensation shall not apply to Virtual Foreign Exchange Traffic (i.e., V/FX Traffic).  As used in this Agreement, Virtual Foreign Exchange Traffic or V/FX Traffic is defined as calls in which a CSPR Customer is assigned a telephone number with an NXX Code (as set forth in the LERG) associated with an exchange that is different than the exchange (as set forth in the LERG) associated with the actual physical location of such Customers station.  For the avoidance of any doubt, CSPR shall pay PRTCs originating access charges for all V/FX Traffic originated by a PRTC Customer, and CSPR shall pay PRTCs terminating access charges for all V/FX Traffic originated by a CSPR Customer.
| | ----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 5.3 | The Reciprocal Compensation rates (including, but not limited to, Reciprocal Compensation per minute of use charges) billed by CSPR to PRTC shall not exceed the Reciprocal Compensation rates (including, but not limited to, Reciprocal Compensation per minute of use charges) billed by PRTC to CSPR, unless the Board establishes higher rates for CSPR based on a CSPR cost study using the forward-looking economic cost based pricing methodology in Sections 51.505 and 51.511 of the FCCs Rules, which proves that the forward-looking costs for a network efficiently configured and operated by CSPR exceed the costs incurred by PRTC, in accordance with 47 C.F.R. § 51.711(b).

due in connection with the Parties exchange of Internet Traffic shall be applied in accordance with Applicable Law.

|7. | Meet-Point Billing Arrangements
|-- | -------------------------------

| | 7.1 | Meet Point Billing arrangements between the Parties for jointly provided Intrastate Exchange Access traffic and Interstate Exchange Access traffic will be governed by this Section.  The Parties will use the Multiple Bill/Multiple Tariff approach described in MECAB.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Under this Multiple Bill arrangement, each Party providing access service will render an access bill to the customer for its portion of the service based on its access tariff rates and regulations.  For switched access billing, the end office company is generally the Initial Billing Company (IBC).  The IBC is the company that calculates the access minutes to be billed to the customer and provides this data to the connecting company providing access service.  The Parties will exchange usage data and other information required under MECAB to implement multiple bill / multiple tariff billing.  Such data and information shall be exchanged in a mutually acceptable medium, which takes into account technical limitations, agreed to by the parties.

| | 7.2 | Each Party will: prepare its own bill; determine its charge(s) for switched transport; determine and include all recurring rates and charges applicable from its access tariff; and forward its bill to the customer.  The customer will remit payment directly to each Party.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 7.3 | Determination of Meet Point Billed Switched Access Transport
| | --- | ------------------------------------------------------------

| | 7.3.1 | Each Partys portion of switched transport will be developed as follows:
| | ----- | ------------------------------------------------------------------------

| | 7.3.1.1 | Determine the appropriate transport mileage by computing the number of airline miles between the end office and access tandem using the V&H method.
| | ------- | ---------------------------------------------------------------------------------------------------------------------------------------------------

| | 7.3.1.2 | Determine the billing percent (BP) as set for the in National Exchange Carrier Association Tariff, F.C.C. No. 4, which represents the portion of the service provided by each Party.
| | ------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 7.3.1.3 | Multiply the number of originating and terminating access minutes of use routed over the facility times the number of airlines miles, as set forth in 7.3.1.1 above times the BP for each Party times the Tandem Switched Facility rate;
| | ------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 7.3.1.4 | Multiply the Tandem Switched Termination rate times the number of originating ad terminating access minutes routed over the facility;
| | ------- | -------------------------------------------------------------------------------------------------------------------------------------

| | 7.3.1.5 | Multiply the Tandem Switching rate times the number of originating and terminating minutes that are switched at the tandem.
| | ------- | ---------------------------------------------------------------------------------------------------------------------------

| | 7.4 | Each Party shall provide the other Party with the billing name, billing address, and Carrier Identification Code (CIC) of the IXC, and identification of the PRTC Wire Center serving the IXC in order to comply with the MPB notification process as outlined in the MECAB document.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | --- | -----------------------------------------------------------------------------

|9. | Tandem Transit Traffic
|-- | ----------------------

| | 9.1 | As used in this Section 9, Tandem Transit Traffic is Telephone Exchange Service traffic that originates on CSPR's network, and is transported through a PRTC Tandem to the Central Office of a CLEC, ILEC other than PRTC, Commercial Mobile Radio Service (CMRS) carrier, or other LEC, that subtends the relevant PRTC Tandem to which CSPR delivers such traffic.  Neither the originating nor terminating customer is a Customer of PRTC.  Subtending Central Offices shall be determined in accordance with and as identified in the Local Exchange Routing Guide (LERG).  Switched Exchange Access Service traffic is not Tandem Transit Traffic.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 9.2 | Notwithstanding anything to the contrary in this Agreement, PRTC will carry CSPR's Tandem Transit Traffic on PRTC's network once CSPR acquires its own switch, unless and until the Board orders otherwise in Case No. JRT-2003-SC-0002.  CSPR' will compensate PRTC for carrying the Tandem Transit Traffic at the minute-of-use (MOU) rate specified in Section 3 of the Pricing Attachment.

Within ninety (90) days of executing this Agreement, CSPR shall provide PRTC a reasonable two (2)-year traffic forecast.  This initial forecast will provide a good faith estimate of the amount of traffic to be delivered to and from PRTC over each of the Interconnection Trunk groups over the next eight (8) quarters.  The forecast shall be updated and provided to PRTC on an as-needed basis, and upon reasonable request, but no less frequently than semiannually.  All forecasts shall include, at a minimum, Access Carrier Terminal Location (ACTL), traffic type (Reciprocal Compensation Traffic/Toll Traffic, Operator Services, 911, etc.), code (identifies trunk group), A location/Z location (CLLI codes for applicable PRTC Tandem and End Office switches to which CSPR wishes to send traffic and the technically feasible Points of Interconnection on PRTCs network at which the Parties will
interconnect), interface type (e.g., DS1), and trunks in service each year (cumulative).

| | 11.2.1 | Initial Forecasts/Trunking Requirements.  Because PRTCs trunking requirements will, at least during an initial period, be dependent on the
| | ------ | -------------------------------------------------------------------------------------------------------------------------------------------

---



Customer segments and service segments within Customer segments to whom CSPR decides to market its services, PRTC will be largely dependent on CSPR to provide accurate trunk forecasts for both inbound (from PRTC) and outbound (to PRTC) traffic.  PRTC will, as an initial matter, provide the same number of trunks to terminate Reciprocal Compensation Traffic to CSPR as CSPR provides to terminate Reciprocal Compensation Traffic to PRTC.  At PRTCs discretion, when CSPR expressly identifies particular situations that are expected to produce traffic that is substantially skewed in either the inbound or outbound direction, PRTC will provide the number of trunks CSPR suggests; provided, however, that in all cases PRTCs provision of the forecasted number of trunks to CSPR is conditioned on the following:  that such forecast is based on reasonable engineering criteria, and that there are
no capacity constraints.

| | 11.2.2 | Monitoring and Adjusting Forecasts.  Each Party will monitor traffic on each trunk group that it establishes at the other Partys request.  After establishing the TCBH, busy season, the parties shall review their forecasts and make any necessary adjustments to individual trunk groups to meet the established service criteria using industry accepted trunk servicing and forecasting techniques.  Each Party will provide the other with peg count usage and overflow on trunk groups originating on its network.  If one party believes particular trunk groups are underutilized, the parties will in good faith seek to make adjustments in order to optimize network utilization.  If the Parties cannot reach agreement on such adjustments, either party may submit the dispute for resolution pursuant to
Section 14.4 of the General Terms and Conditions.
| | ------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 11.2.2.1 | Both Parties may also monitor traffic on additional trunk groups that CSPR suggests or requests PRTC to establish.  The parties will work together to identify substantial over- or under-trunked groups and to locate blocking within the two networks using industry accepted trunk servicing and forecasting techniques.  If either party believes the trunk group is underutilized, the parties will proceed under Section 11.2.2 of this Attachment.

| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|4. | Responsibility for Charges
|-- | --------------------------

CSPR shall be responsible for and pay all charges for any PRTC Telecommunications Services provided by PRTC pursuant to this Resale Attachment subject to the terms and conditions provided in Section 9 of the General Terms and Conditions.  PRTC will notify CSPR directly and in writing (to the extent not otherwise filed with the Board or posted on PRTCs website) of any customer specific pricing arrangements, ICBs, and/or promotions that PRTC is required to make available to CSPR in accordance with applicable law, including but not limited to 47 U.S.C. §§ 251 & 252 and 47 C.F.R. § 51.613.  Consistent with the terms of such arrangements, CSPR will be able to purchase any retail telecommunications services available in those arrangements at the prices in the arrangement plus the appropriate wholesale discount.   For example if PRTC offers an ICB providing a discount of
10% to a customer that includes non-regulated items in its package ($15,000 regulated items $1,000 non regulated) CSPR will have a 10% discount (in addition to the already applicable resale discount) on all regulated services the current customer is receiving (10% additional on the $15,000).  If the appropriate wholesale discount is 25%, CSPR will be eligible to receive 35% on the $15,000, and will be able to offer it to that customer absorbing whatever contract may be in place.  PRTC may include in its customer specific pricing arrangements termination liabilities that are consistent with rules of the FCC.  In the event that CSPR agrees to honor the terms of the contract until completion, no termination liability shall apply; provided, however, that CSPR pays PRTC the difference between PRTCs normally applicable tariffed rate and the discounted rates in the ICB for the underlying services for the period of time that the ICB was initially effective until CSPRs agreement to
honor the terms of the contract.

| | 3.1.11 | PRTC requires CSPR to request the grade of service desired in a particular Local Loop (e.g., ISDN-BRI, PRI, ADSL, HDSL, DS1) so that the Loop may be engineered to meet the appropriate spectrum compatibility requirements. If CSPR requires a change in the grade of service of a particular Local Loop (e.g., changing from ISDN service to ADSL), CSPR shall notify PRTC of the requested change in grade of service. If PRTC reasonably finds that it is not technically feasible to provide the new level of service to CSPR, PRTC will notify CSPR that it is unable to meet CSPR's request.

| | 3.1.12 | PRTC reserves the right to limit the provisioning of BRI capable Local Loops in some areas served by Local Loop facilities and/or transmission equipment that are not compatible with BRI and/or DS1 service.  PRTC reserves the right to make some cables and/or binder groups unavailable to CSPR based on spectrum management considerations.  PRTC's reservation of rights set forth herein shall only be exercised on a nondiscriminatory basis, i.e., to the same extent that PRTC provisions or restricts facilities for itself and others, and in accordance with Applicable Law.  Moreover, when PRTC designates a cable and/or binder groups as unavailable due to spectrum consideration, PRTC shall make available to CSPR, upon request, technical documentation justifying such decision.   PRTC may utilize repeater or repeater-less ISDN
technology to provide the ISDN Loop to CSPR.  End to end Local Loop performance is still contingent upon the underlying make-up of the existing Local Loop.

|-- | -------------------

| | 2.1 | Collocation allows CSPR to obtain dedicated space in a PRTC Premises and to place equipment in such spaces necessary to interconnect with the PRTC network or to gain access to PRTC's unbundled network elements.  CSPR may request Collocation at other PRTC locations not otherwise specified in this Agreement pursuant to Section 251 of the Act.  PRTC-designated Points of Interconnection (POIs) for network interconnection can be established for Virtual and/or Physical (including Cageless, Shared, and Adjacent Space) Collocation arrangements.  PRTC shall designate POIs as close as reasonably possible to its Premises.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 2.2 | Except when CSPR purchases PRTC's unbundled network transmission elements, or the services or facilities of another carrier, CSPR may construct its own fiber optic cable or other facilities to the PRTC-designated Point of Interconnection or employ a PRTC-approved contractor to perform such construction.PRTC will extend CSPR's facilities from the POI to the cable vault within the Premises.  For the purposes of Collocation, the POI shall be that point outside the PRTC Premises where the CSPR and PRTC fibers meet.  If necessary, PRTC may bring the cable into compliance with PRTC fire code standards (so long as reasonably consistent with industry standards) and extend the cable to the collocated space.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 2.3 | Upon reasonable request by CSPR or upon the order of the Board, PRTC will remove obsolete unused cabling to free up entrance ducts when no other ducts are available.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 2.4 | CSPR may collocate and use in its collocated space any equipment necessary for interconnection with PRTC or access to PRTC unbundled network elements.  As provided in Section 51.323(b)(1) and (2) of the FCCs Rules, equipment is necessary for interconnection if an inability to deploy that equipment would, as a practical, economic, or operational matter, preclude CSPR from obtaining interconnection with PRTC at a level equal in quality to that which PRTC obtains within its own network or PRTC provides to any affiliate, subsidiary, or other party.  Equipment is necessary for access to an unbundled network element if an inability to deploy that equipment would, as a practical, economic, or operational matter, preclude CSPR from obtaining nondiscriminatory access to that unbundled network element, including any of its
features, functions, or capabilities.  Permissible collocation equipment includes, but is not limited to, transmission equipment (including, but not limited to, optical terminating equipment and multiplexers), equipment being collocated to terminate basic transmission facilities, digital subscriber line access multiplexers (DSLAMs), routers, and asynchronous transfer mode (ATM) equipment, but only where such equipment is necessary for interconnection with PRTC or access to PRTC's unbundled network elements.

| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 3.4 | For caged physical collocation, the minimum standard lease able amount of floor space is 100 square feet.  PRTC may impose reasonable restrictions on the warehousing of unused space by CSPR, provided, however, that PRTC shall not set maximum space limitations applicable to CSPR unless PRTC proves to the Board that space constraints make such restrictions necessary.  PRTC may retain a reasonable amount of floor space for its own specific future uses; provided, however, that PRTC nor any of its affiliates may reserve space for future use on terms more favorable than those that apply to CSPR when it may seek to reserve collocation space for its own future use.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 3.5 | CSPR's leased floor space will be separated from other competitive providers and PRTC space through a cage enclosure except in the case of Cageless Collocation. Such requirement, however, will only apply where (1) such separation is warranted by legitimate security concerns or operational constraints unrelated to PRTCs or any of its affiliates or subsidiaries competitive concerns, (2) any collocation space assigned to a PRTC affiliate or subsidiary is separated from space housing PRTC equipment, (3) the separated space will be available in the same time frame as, or a shorter time frame than, non-separated space, (4) the cost of the separated space to CSPR will not be materially higher than the cost of non-separated space, and (5) the separated space is comparable, from a technical and engineering
standpoint, to non-separated space.  CSPR may elect to have PRTC construct the cage, or choose from PRTC approved contractors to construct the cage, meeting PRTC's reasonable installation technical requirements.  PRTC shall not unreasonably withhold approval of contractors selected by CSPR and such approval shall be based on the same criteria PRTC uses in approving contractors for its own purposes.  CSPR must determine at the time of application whether PRTC or an approved contractor will construct the cage enclosure.

| | 3.6 | PRTC Responsibilities.  PRTC will have the following responsibilities in connection with the provision of collocation space to CSPR.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------

| | 3.6.1 | Designate the floor space within each Premises which will constitute CSPR's leased space.  PRTC reserves the right (based on legitimate and documented reasons not reasonably foreseeable at the time of the original designation, to redesign ate the floor space within each Premises which will constitute CSPR's leased space.  PRTC will bear

| | ------- | -----------------------------------------------------------------------------------------------------------------------------

| | 3.6.5.4 | PRTC space assignment must not reduce unreasonably the total space available for collocation or preclude unreasonably collocation within PRTC Premises.
| | ------- | -------------------------------------------------------------------------------------------------------------------------------------------------------

| | 3.6.5.5 | PRTC must provide a written explanation to CSPR in the event it does not grant a CSPR preference.
| | ------- | -------------------------------------------------------------------------------------------------



| | 3.6.6 | Upon request and at CSPRs reasonable expense, to the extent PRTC is entitled to recover such expense under Applicable Law, PRTC must remove obsolete unused equipment from its Premises to increase the amount of space available for collocation.
| | ----- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3.7 | CSPR Responsibilities.  CSPR will have the following responsibilities in connection with the provision of collocation space to CSPR.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------

| | ------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 3.7.3 | Install, maintain, repair and service all CSPR's equipment located in the leased physical space.  CSPR will promptly repair or replace all defective equipment.  CSPR and its agents shall comply with PRTC's collocation procedures in performing any installation, maintenance, repair, or service of CSPR equipment, in accordance with Section 2.7 of this Attachment.
| | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 3.7.4 | Ensure that all equipment installed by CSPR complies with any statutory (local, federal, or Commonwealth) or regulatory requirements in effect at the time of equipment installation or that subsequently become effective.  These requirements apply only to the extent they are not more stringent than the safety requirements that PRTC imposes on its own equipment that it locates in its premises.
| | ----- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 3.7.5 | CSPR is responsible for obtaining reasonable insurance coverage, including but not limited to fire, theft, and liability.  CSPRs insurance must also cover all virtually collocated equipment.
| | ----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 3.7.6 | CSPR will be responsible for the actions and inactions of its employees, vendors, or contractors who have access to PRTC's Central Office equipment, property, and other facilities.  PRTC will be responsible for the actions of its employees, vendors, or contractors who have access to CSPRs collocation space equipment, property, and other facilities.
| | ----- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 3.7.7 | In the event of a PRTC work stoppage or strike, CSPR's employees, contractors, or agents will comply with reasonable established emergency operating procedures in accordance with Section 2.7 of this Attachment.  PRTC will take reasonable steps to ensure CSPR continued access to its collocation space during the work stoppage.
| | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 3.7.8 | All CSPR employees, agents, or contractors must remain at all times in the designated area of the Central Office to which they are authorized.  CSPR's employees, agents or contractors must not touch or utilize any PRTC equipment or systems to which they are not authorized.  PRTCs employees, agents or contractors must not touch or utilize any of CSPRs equipment or systems to which they are not authorized.  The provisions of this section, however, shall not restrict contact or utilization of equipment or systems to the extent such contact or utilization is reasonably necessary to protect persons or equipment from significant and immediate injury or harm.
| | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 3.8 | If, at any time, PRTC reasonably determines that the equipment or the installation do not meet  the requirements of this Agreement, such failure being due to the actions or inactions of CSPR or its agents, CSPR will be responsible for the costs associated with the removal, modification to, or installation of the equipment to bring it into compliance.  If CSPR fails to correct (or make substantial progress toward correcting) any non-compliance as soon as reasonably practical, but, in any event, no later than thirty (30) days after the receipt of written notice of the non-compliance, PRTC may have the equipment removed or the condition corrected at CSPR's reasonable expense.  As a general proposition, PRTC may immediately remove CSPR equipment if PRTC reasonably determines that such equipment poses a material, immediate
threat

to safety or causes an interruption to service and that such threat cannot reasonably be addressed by notice to CSPR.  Furthermore, PRTC may remove CSPR equipment after reasonable notice to CSPR, if PRTC reasonably determines that such equipment threatens to interrupt service.  PRTC will remove said equipment at CSPR's reasonable expense.  Except in cases of emergency, in the event CSPR notifies PRTC that it, in good faith, disputes a PRTC determination under this Section, PRTC may not remove the subject CSPR equipment until the formal resolution of such dispute in its favor or upon an order from the Board.

| | 3.9 | If, during installation, PRTC reasonably determines that CSPR's activities or equipment are unsafe or in violation of any Applicable Laws or regulations, PRTC has the right to stop work until the situation is reasonably remedied.  If such conditions pose an immediate threat to the safety of PRTC employees, interfere with the performance of PRTC's service obligations, or pose an immediate threat to the physical integrity of the conduit system or the cable facilities, PRTC may perform such work and/or take action as is necessary to correct the condition at CSPR's reasonable expense.  Except in cases of emergency, in the event CSPR notifies PRTC that it, in good faith, disputes a PRTC determination under this Section, PRTC may not stop the subject CSPR installation until the formal resolution of such dispute in its favor
or upon an order from the Board.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 3.10 | In exercising its rights under Sections 3.8 and 3.9 of this Attachment, PRTC shall act with reasonable care and will take reasonable steps to minimize damage to CSPR equipment.
| | ---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 3.11 | PRTC may not require CSPR to use an intermediate interconnection arrangement in lieu of direct connection to PRTC if technically feasible.
| | ---- | ------------------------------------------------------------------------------------------------------------------------------------------

| | 3.12 | PRTC must prorate the charge for site conditioning and preparation undertaken by PRTC to construct or condition a space for collocation use by determining the total charge for site preparation and allocating that charge to CSPR based on the percentage of total space utilized by CSPR.
| | ---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4. | Additional Physical Collocation Offerings
|-- | -----------------------------------------

| | 4.1 | Upon request, PRTC shall provide three other forms of Physical Collocation as set forth in and in accordance with 47 C.F.R § 51.323 (k): Cageless Collocation, Shared Collocation Cages and Adjacent Space Collocation.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 4.1.1 | Cageless collocation.  Cageless collocation allows CSPR to install equipment that is necessary for interconnection with PRTC or access to PRTC's unbundled network elements within the same conditioned environment as the PRTC's equipment, without requiring the construction of a cage or similar structure.  CSPR would be provided space designated by PRTC within the Premises, in the same environment as the PRTC's equipment, but with sufficient physical separation (e.g., a specific aisle) to clearly distinguish CSPR's equipment from PRTC's equipment.  CSPR will be responsible for the installation, maintenance and repair of its equipment in this collocation arrangement.  CSPR will be provided direct access to its equipment.  Moreover, PRTC may not require CSPR to use an intermediate interconnection arrangement in lieu of
direct connection to PRTC if technically feasible.  PRTC shall make cageless collocation space available in single-bay increments, meaning that CSPR can purchase
| | ----- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

space in increments small enough to collocate a single rack, or bay, of equipment.

| | 4.1.2 | Shared Collocation Cages.  This form of collocation establishes caged collocation space shared by two or more CLECs pursuant to terms and conditions agreed to by the CLECs and that is dedicated to the collocation of CLEC equipment that is necessary for interconnection or access to unbundled network elements.  This shared area would be separated from PRTC equipment, but within the shared space.  Each CLEC sharing collocation space must enter into its own interconnection agreement with PRTC.  These shared areas would be fully accessible to the CLECs authorized employees or agents for installation, maintenance and repair. PRTC will make shared collocation space available in single-bay increments small enough to collocate a single rack, or bay, of equipment.    In making shared cage arrangements available to CSPR,
PRTC may not increase the cost of site preparation or nonrecurring charges above the cost for provisioning such cage of similar dimensions and material to a single collocating party,  In addition, PRTC must prorate the charge for site conditioning and preparation undertaken by PRTC to construct the shared collocation cage or condition the space for collocation use, regardless of how many carriers actually collocate in that cage, by determining the total charge for site preparation and allocating that charge to a collocating carrier based on the percentage of total space utilized by that carrier.
| | ----- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 4.1.3 | Adjacent Space Collocation.  Adjacent Space collocation allows CSPR to install equipment that is necessary for interconnection with PRTC or access to PRTC's unbundled network elements in adjacent controlled environmental vaults, controlled environmental huts, or similar structures located at or near PRTC Premises to the extent technically feasible.  PRTC will permit CSPR to construct or otherwise procure such an adjacent structure, subject to reasonable and nondiscriminatory safety and maintenance requirements in accordance with Section 2.7 of this Attachment.  CSPR may also secure adjacent collocation space on neighboring private property as long as such an arrangement is technically feasible.  CSPR will be responsible for the installation, maintenance and repair of its equipment in this collocation arrangement.  If
physical collocation space becomes available in a previously exhausted PRTC structure, PRTC may not require CSPR to move, or prohibit CSPR from moving, a collocation arrangement into that structure.  Instead, PRTC must continue to allow CSPR to collocate in any adjacent controlled environmental vault, controlled environmental hut, or other similar structure that CSPR has constructed or otherwise procured.
| | ----- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 4.2 | CSPR may order Shared and Cageless Collocation space on a single bay increment, including, but not limited to earthquake bracing and galvanized steel bay configuration.  PRTC's standard equipment bay configurations will apply.  PRTC shall provide such space in an efficient, reasonable, and non-discriminatory manner.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 4.3 | For Physical Collocation, CSPR must place and maintain its own equipment in Collocation space at its own expense.
| | --- | -----------------------------------------------------------------------------------------------------------------

|5. | Virtual Collocation
|-- | -------------------

| | 5.1 | PRTC shall provide to CSPR Virtual Collocation for the purpose of interconnection with PRTC or access to PRTC's Unbundled Network Elements.  Virtual Collocation enables CSPR to designate or specify equipment to be located within or upon a PRTC Premises and to electronically monitor its communications channels terminating in such equipment.  PRTC has physical control of such equipment.  If installation is performed by a PRTC-approved contractor, PRTC will charge CSPR for supervision of the PRTC-approved contractor at the rate provided in the Pricing Attachment to the same extent PRTC requires supervision of such contractor when such contractor performs work for PRTC.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 5.2 | CSPRs equipment installation must be made in accordance with the provisions specified by PRTC engineering procedures in accordance with Section 2.7 of this Attachment.  Prior to placing the equipment in service, PRTC will audit the installation for compliance with those provisions.  Any installation found not in material compliance will not be placed in service.  Other instances of non-compliance will be brought into compliance as soon as reasonable necessary under the circumstances.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 5.3 | Intentionally omitted.
| | --- | ----------------------

| | 5.4 | CSPR will provide for training, and retraining as needed, of a mutually acceptable number of PRTC employees to provide requested maintenance and repair of any equipment used to provide virtual collocation which is otherwise not used by the PRTC at the specific office.  CSPR must either provide its own trainer or contract directly with a training vendor to train PRTC personnel.  CSPR will also provide PRTC with manuals and other information about the CSPRs equipment, including safety materials, from CSPRs equipment manufacturer.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 5.5 | CSPR will pay the reasonable hourly fee in the Pricing Attachment for each PRTC employee requiring training.  CSPR may be responsible for other reasonable PRTC personnel training related expenses (a good faith estimate disclosed to CSPR in advance) such as transportation reimbursement, room, board and any fees assessed by CSPRs selected training vendor.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 5.6 | CSPR may choose not to provide training to PRTC employees in advance.  In that event, CSPR will provide real-time training and trouble shooting, and the hourly maintenance charges contained in the Pricing Attachment would apply.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 5.7 | PRTC is responsible for requested maintenance of facilities between the meet point and the central office and all equipment within the central office used to provide virtual collocation to CSPR.  CSPR is responsible for monitoring the performance of all facilities and equipment used in the provision of virtual collocation, and for initiating requests for maintenance of said facilities and equipment by PRTC.  PRTC does not assume responsibility for the design, engineering, testing, or performance of the virtual collocation with Unbundled Network Elements or other services.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 5.8 | Equipment and facilities used in provisioning virtual collocation shall be maintained only upon written request of CSPR and shall be on time-sensitive or time and material basis at the hourly rate in the Pricing Attachment.  If CSPR does not provide maintenance spares at a virtual collocation location, and PRTC provides a spare from its available stock at CSPRs request, CSPR will be charged the reasonable cost of the material provided.  For maintenance or repair requested outside of normal business hours, CSPR will be required to pay for
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

time spent by PRTC personnel for delivery if: (1) the required spares are not available at the central office; or (2) the required test equipment is not available at the central office.  PRTC will also charge on a time-sensitive or time and materials basis for acceptance, cooperative and end-to-end testing, as well as oversight of CSPR activities within PRTC locations (supervision).  CSPR will be charged the hourly rates for such labor at the rate in the Pricing Attachment.  For any maintenance or testing assistance requiring as call-out of a PRTC technician, CSPR will be charged a minimum of two hours starting from the time of notification.  PRTC will establish an average hourly rate for maintaining CSPRs virtually collocated equipment based on the equipment installed.  PRTC will detail any additional charges, e.g., out-of-hours charges, the charges for maintenance spare plug-ins, and
under what conditions such charges apply.  PRTC will develop PRTCs charge rates thirty (30) days following receipt of CSPRs proposed equipment list and configuration.

|6. | Collocation Application Process
|-- | -------------------------------

| | 6.1 | To apply for collocation under this Article, CSPR shall complete and submit the required PRTC Collocation Application (a copy of which is attached hereto or posted on PRTCs Internet site) and remit all required application fees to PRTC.  This procedure, including paperwork, may be reasonably modified by PRTC only upon thirty (30) days written notice, and receipt of the new forms needed, including by posting such information on PRTCs Internet site.  If CSPR subsequently makes more than de minimis modifications to CSPRs application for collocation, CSPR  will be responsible for paying PRTC for the additional expense to process modified application as specified in the Pricing Attachment.  In addition, the time frames below will restart upon PRTCs receipt of a materially modified application.   The
fees for the application, including changes to the application, and separate engineering fees are contained in the Pricing Attachment.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 6.2 | As part of the Application, CSPR must indicate whether PRTC or a PRTC-approved contractor will perform those activities not specifically reserved to PRTC employees.  If installation is performed by a PRTC-approved contractor, PRTC will charge CSPR at the rate provided in the Pricing Attachment for supervision of the PRTC-approved contractor to the same extent PRTC requires supervision of such contractor when such contractor performs work for PRTC.  For example, if CSPR chooses to use a PRTC-approved contractor to build a collocation cage, PRTC will determine the number of hours of supervision PRTC would require if the PRTC-approved contractor were doing such work for PRTC.  PRTC will then include that number of hours of supervision in the estimated collocation costs.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 6.3 | PRTC will respond to CSPR within ten (10) calendar days of the date of the CSPRs application with information concerning collocation availability or the rejection of CSPR's request.  CSPR will accept or reject the PRTC confirmation within seven (7) calendar days.  By accepting the PRTC confirmation, the Parties agree that CSPR does not waive the right to dispute, and may subsequently dispute, any charges not contained in the Pricing Attachment that are assessed by PRTC in its confirmation and that such dispute will not delay PRTCs provision of the collocation requested; provided that CSPR may dispute the number of units to which the rate in the Pricing Attachment applies.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 6.4 | The fees contained in the Pricing Attachment are based on a fiber interface.  If CSPR wants to use any non-fiber interface for collocation, PRTC will accommodate such interconnection if technically feasible.  The prices for such
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

interface will be determined on an individual case basis within thirty (30) calendar days of the date of CSPRs application.

| | 6.5 | Upon CSPRs acceptance of the PRTC collocation confirmation, CSPR shall remit to PRTC fifty (50) percent of the estimated collocation costs.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------

| | 6.6 | Pursuant to the completion and finalization of the requirements specified in subsections 6.1-6.5 above, where collocation space and associated requirements are available as determined in accordance with Section 3.1 of this Attachment, caged and cageless physical collocation shall be provided within ninety (90) calendar days.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 6.6.1 | If CSPR fails to provide PRTC with confirmation within seven (7) calendar days as required by Section 6.3, PRTCs timeframe for providing physical collocation extends one day for each day the CSPRs response is late.
| | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 6.6.2 | If CSPR fails to provide forecasts as required by Section 7 of this section, PRTC physical collocation shall be provided within one hundred and ten (110) calendar days.
| | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 6.7 | Pursuant to the completion and finalization of the requirements specified in subsections 6.1-6.6 above, and where space and power are readily available, the collocation space for virtual collocation, shall be provided within sixty (60) calendar days.  Where space or power is not readily available, the virtual collocation space shall be made available in 110 calendar days.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 6.8 | CSPR shall file a new application for any requested changes to existing collocation arrangements and pay the fee contained in the Pricing Attachment.  A new application will not be required for adding plug-ins to existing shelves or similar minor changes.  Changes to any cabling arrangement shall be provided within thirty (30) calendar days of the date of the CSPRs application.  With respect to any changes involving HVAC and power changes to existing collocation arrangements, PRTC will respond to CSPR within ten (10) calendar days of the date of the CSPR application, notifying CSPR of the changes required and providing approximate costs and scheduling information.  CSPR will be responsible for all engineering and planning costs incurred by PRTC in preparing a response to CSPRs request for changes, regardless
of whether CSPR ultimately decides to implement the change.  CSPR must remit to PRTC 50% of the costs involved in any change prior to PRTC beginning implementation of the requested work.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 6.9 | Should PRTC deny a CSPR request for physical collocation on the basis that space is not available in the central office at issue, PRTC shall provide the Board with detailed floor plans or diagrams of any premises where physical collocation is denied due to space limitations.  Further, at CSPR's election, PRTC shall escort CSPR representatives on a tour of the entire PRTC Premises at issue within ten (10) calendar days of the receipt of the denial by CSPR.  PRTC shall provide CSPR with detailed floor plans or diagrams of any premises where physical collocation is denied due to space limitation for the duration of such tour.  Prices for such tours, escorts and floor plans or diagrams are specified in the Pricing Attachment.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 6.10 | Prior to PRTC performing the construction of any physical collocation arrangements requested by CSPR, the Parties shall, within ten (10) calendar days following CSPR's acceptance of PRTCs collocation confirmation, meet to establish an installation schedule that will allow PRTC and CSPR installation

efforts to proceed in parallel without jeopardizing the safety of either Party's personnel.

| | 6.11 | To the extent that space for physical collocation is not available, PRTC shall provide CSPR with virtual collocation.
| | ---- | ---------------------------------------------------------------------------------------------------------------------

| | 6.12 | Intentionally omitted.
| | ---- | ----------------------

| | 6.13 | Upon request, PRTC shall submit to CSPR within ten (10) calendar days of the submission of the request a report describing in detail the space that is available for collocation in a particular PRTC Premises.  This report must specify the amount of collocation space available at each requested Premises, the number of collocators, and any modifications in the use of the space since the last report.  This report must also include measures that PRTC is taking to make additional space available for collocation.  PRTC must maintain a publicly available document, posted for viewing on PRTCs publicly available Internet site, indicating all Premises that are full, and must update such a document within ten (10) calendar days of the date at which a Premises runs out of physical collocation space.

If any condemnation proceeding shall be instituted in which it is sought to take or damage any part of the property, or if the grade of any street or alley adjacent to the property is changed by any competent authority and such change of grade makes it necessary or desirable to remodel the property to conform to the
changed grade, PRTC shall have the right to terminate a Collocated Space agreement upon not less than thirty (30) calendar days notice prior to the date of cancellation designated in the notice.

| | --------- | ----------------------------------------------------------------------------------------------------------------------------------------

| | 8.25.15.3 | CSPR shall return to PRTC the Collocated Space and all equipment and fixtures of PRTC in as good a condition and state of repair as when CSPR originally took possession, reasonable wear and tear excepted.

equipment and restoration of the Collocated Space, including, without limitation, PRTC's directive to return the Collocated Space in other than its original condition on the date of occupancy; provided, however, that CSPR shall not be responsible for putting the Collocated Space in other than its original condition if to do so would put CSPR to additional expense above and beyond that which would be necessary to return the Collocated Space in its original condition.

| | 8.25.15.4 | All installations, additions, hardware, non-trade fixtures and improvements, temporary or permanent, except movable furniture and equipment belonging to CSPR, in or upon the Collocated Space, whether placed there by CSPR or PRTC, shall be PRTC's property and shall remain upon or in the Collocated Space, all without compensation, allowance or credit to CSPR; provided, however, that if prior to such termination or within ten (10) business days thereafter, PRTC so directs, CSPR shall promptly remove the installations, additions, hardware, non-trade fixtures and improvements, placed in or upon the Collocated Space by CSPR, failing which PRTC may remove the same, and CSPR shall, upon demand, pay to PRTC the reasonable cost of such removal and of any necessary restoration of the Collocated Space. No cable shall be removed
from inner duct or outside cable duct except as directed by PRTC.
| | --------- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 8.25.15.5 | Following the period set forth in Section 8.25.15.2 of this Attachment, all fixtures, installations, and personal property belonging to CSPR not removed from the Collocated Space upon termination of a Collocated Space license and not required by PRTC to have been removed as provided in this Section shall be conclusively presumed to have been abandoned by CSPR and title thereto shall pass to PRTC under this Section as if by a bill of sale.

| | --------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 8.25.16 | If the owner of the building or PRTC sells, transfers or assigns any interest in the building, or there is any material change in the lease to which the building is subject, and such sale, transfer, assignment or material change in the lease gives rise to an obligation which is inconsistent with a Collocated Space agreement granted under this Attachment, PRTC's performance under this Section shall be excused to the extent of the inconsistency. PRTC acknowledges the substantial disruption and harm to CSPRs network and end user customers that could be caused and will use its commercially reasonable efforts to avoid any such inconsistency; provided, however, that this obligation shall in no way obligate PRTC to incur any material out of pocket expenses in its efforts to avoid such inconsistencies.

| | ----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 9.1.3 | PRTC shall limit the keys used for CSPR's caged Collocated Space which contains or houses CSPR equipment or equipment enclosures to PRTC employees and representatives to emergency access only.

safeguards. Except in emergencies or unless CSPR has waived such notice elsewhere in this Section, and if conditions permit, PRTC will provide CSPR with reasonable advance notice of its intent to access the Collocated Space, thereby providing CSPR the option to be present at the time of access. CSPR shall not attach, or permit to be attached, additional locks or similar devices to any door or window, nor change existing locks or the mechanism thereof.

| | 9.2 | PRTC may charge CSPR a reasonable fee that recovers the reasonable cost of specific security arrangements above and beyond what existed prior to CSPRs collocation and that are directly attributable to CSPR and as allowed under Applicable Law and the requirements of this Agreement.  PRTC shall provide to CSPR advance notice of such costs, including any documentation and explanation underlying such costs.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
