3.0 [Intentionally left blank]

4.0 INTERCONNECTION ARRANGEMENT

The types of traffic to be exchanged under this Agreement shall be Local Traffic and IntraLATA Toll Traffic.

4.1 Scope

4.1.1 Section 4 describes the architecture for direct Interconnection of the Parties' facilities and equipment over which the Parties shall configure the following trunk groups:

4.1.1.1 Interconnection trunks ("Interconnection Trunks" or "Interconnection Trunk Group[s]")for the transmission and routing of Local Traffic, IntraLATA Toll Traffic and translated (post-query) intraLATA 800/888 traffic between their respective Telephone Exchange Service Customers in accordance with Section 5 below. Interconnection Trunks shall be designed and configured for two-way operation.

4.1.2 For the purposes of this Agreement, the Parties agree that Interconnection for the transport and termination of traffic may take place indirectly via a third party's Tandem Transit arrangement or directly at a terminating End Office, a Tandem, a Wire Center, any mutually agreed-upon Mid-Span Meet or Shared Fiber Meet arrangement as provided in Sections 4.2 to 4.4 below, and/or other points as specified herein. Notwithstanding the foregoing, sentence, the Parties shall consider and discuss the establishment of two-way direct End Office trunk groups when the volume of transit traffic originating from one Party and passing through the appropriate ILEC Tandem switch to which both Parties are directly connected, and terminating at the other Party, exceeds the CCS busy hour equivalent of one (1) DS-1 equivalent trunks, on a monthly average basis, for each month of any three (3) consecutive months.

4.1.3 Where direct Interconnection is used, the Parties shall establish mutually agreed-upon interconnection points (collectively, the "Points of Interconnection" or "POIs").

4.1.4 Where direct Interconnection is used, the Parties shall configure separate trunk groups (as described in subsection 4.1.1 and 4.1.2 above) for traffic between Cox and Pac-West. Where indirect Interconnection is used, each Party shall be responsible for ensuring that it has sufficient facilities in place to each third party Tandem Transit arrangement used to exchange traffic between the Parties' networks.

4.2 Physical Architectures

4.2.1 In each LATA where direct Interconnection is used, the Parties shall utilize the POI(s) designated as the points from which the Parties will provide the transport and termination of traffic. Each Party is operationally and financially responsible for bringing its facilities (and the originating traffic over those facilities) to the POI(s).

4.2.2 The Parties may mutually agree to any of the following methods for direct Interconnection:

(a) a Physical Collocation facility established separately by a Party or by a third party with whom Cox or Pac-West has contracted for such purposes;

(b) an entrance facility and transport (and any necessary multiplexing) provided by or leased from a Party or a third party, pursuant to its effective Tariff;

(e) any other mutually-agreed to arrangement, as negotiated by the Parties.

4.2.3 Each Party shall provide its own facilities or purchase necessary transport for the delivery of traffic to any agreed-to POI; where facilities are shared, each Party shall pay its proportionate share of the cost of the jointly-used facilities.

4.2.4 The Parties may order any of the Interconnection methods specified above in accordance with the order intervals and other terms and conditions, including, without limitation, rates and charges, set forth in this Agreement, in any applicable Tariff(s) or as may be subsequently agreed to between the Parties.

4.3 Mid-Span Meets

4.3.1 The Parties may agree to establish (i) a Mid-Span Meet arrangement in accordance with the terms of this subsection 4.3 that utilizes wireline transmission facilities. In a Mid-Span Meet, each Party extends its facilities to meet the other Party. The point where the facilities meet is the Mid-Span point. Each Party bears its own costs to establish and maintain a Mid-Span Meet arrangement, and/or shares any common costs associated with the arrangement. However, the Parties also agree that a technical arrangement for a Mid-Span Meet may involve one Party placing and extending its own (or leased) fiber facilities to the Wire Center of the other Party, with sufficient additional length on the fiber to permit the receiving Party to terminate the fiber without requiring splicing of the fiber facilities prior to the terminal equipment in the receiving Party's Wire Center. In this situation, the Parties will negotiate reasonable compensation to be paid to the Party extending the facilities for the associated labor, materials, and conduit space used in extending its facilities beyond a negotiated Mid Span point.

4.3.2 The establishment of any Mid-Span Meet arrangement is expressly conditioned upon the Parties' reaching prior agreement on appropriate sizing and forecasting, equipment, ordering, provisioning, maintenance, repair, testing, augment, and compensation procedures and arrangements, reasonable distance limitations, and on any other arrangements necessary to implement the Mid-Span Meet arrangement. Any Mid-Span Meet arrangement requested at a third-party premises is expressly conditioned on the Parties' having sufficient capacity at the requested location to meet such request, on unrestricted 24-hour access for both Parties to the requested location, on other appropriate protections as deemed necessary by either Party, and on an appropriate commitment that such access and other arrangements may not be restricted for a reasonable period.

4.3.3 Mid-Span Meet arrangements shall be used only for the termination of Local Traffic and IntraLATA Toll Traffic, unless and until such time as the Parties have agreed to appropriate compensation arrangements relating to the exchange of other types of traffic over such Mid-Span Meet, and only where facilities are available.

4.3.4 A Mid-Span Meet arrangement may be implemented by establishing direct End Office interconnection using an electrical or optical cross-connect between the Parties' respective collocation arrangements at the appropriate third-party LEC Central Office. Each Party will pay 50% of the non-recurring and recurring costs of the cross-connects provisioned by the third-party LEC. Except for the splitting of cross-connect costs, each Party shall be operationally and financially responsible for its own facilities on its side of the Interconnection Point.

4.3.5 The Parties' agree to initially establish direct End Office Trunking arrangements in accordance with Appendix 2 to this Agreement. Appendix 2 of the Agreement may be revised from time to time upon the mutual agreement of the Parties to reflect additional or changed interconnection arrangements in Arizona utilizing the Mid-Span Meet arrangement discussed in Section 4.3.4 above or any other method available under Section 4.

5.0 TRANSMISSION AND ROUTING OF TELEPHONE EXCHANGE SERVICE TRAFFIC

5.1 Scope of Traffic

Section 5 prescribes parameters for trunk groups to be effected over the Interconnections specified in Section 4 for the transmission and routing of Local Traffic, translated (post-query) LEC IntraLATA 800/888 traffic, and IntraLATA Toll Traffic between the Parties' respective Customers.

5.2 Trunk Group Connections and Ordering

5.2.1 Where direct Interconnection is used, trunk group connections will be made at a DS-1 level, DS-3 level, OC-3 level or higher. Higher speed connections shall be made, when and where available, in accordance with the Joint Implementation and Grooming Process prescribed in Section 10.

5.2.3 Each Party will identify its Carrier Identification Code, a three or four digit numeric obtained from Telcordia (formerly "Bellcore"), to the other Party when ordering a trunk group.

5.3 Additional Switching System Hierarchy and Trunking Requirements

For purposes of routing Cox traffic to Pac-West, the subtending arrangements between Pac-West Tandem Switches (or functional equivalent) and Pac-West End Office Switches (or functional equivalent) shall be the same as the Tandem/End Office subtending arrangements Pac-West maintains for the routing of its own or other carriers' traffic. For purposes of routing Pac-West traffic to Cox, the subtending arrangements between Cox Tandem Switches (or functional equivalent) and Cox End Office Switches (or functional equivalent) shall be the same as the Tandem/End Office subtending arrangements (or functional equivalent) which Cox maintains for the routing of its own or other carriers' traffic.

5.4 Signaling

Each Party will provide the other Party with direct or indirect access to its databases and associated signaling necessary for the routing and completion of the other Party's traffic in accordance with the provisions contained in Section 14 below. In addition, where direct trunk Interconnection is used, the Parties will use SS7 signaling; where indirect trunk Interconnection is used, the Parties will ensure that SS7 signaling is used end-to-end.

5.5 Grades of Service

Where direct Interconnection is used, the Parties shall initially engineer and shall jointly engineer and maintain all trunk groups consistent with the Joint Implementation and Grooming Process as set forth in Section 10.

5.6 Measurement and Billing

5.6.1 The terminating Party shall be responsible for creating or obtaining any billing records needed in order to xxxx the originating Party terminating access minutes of use. Measurement of minutes of use shall be in actual conversation seconds. The total conversation seconds over each Interconnection trunk group will be totaled for the entire monthly billing cycle and then rounded to the next whole minute.

5.6.2 For billing and/or self-auditing purposes, whether direct or indirect Interconnection is used, each Party shall pass Calling Party Number ("CPN") information on at least ninety percent (90%) of calls carried over the Interconnection Trunks. If the originating Party passes CPN on less than ninety percent (90%) of its calls, the terminating Party shall xxxx its intrastate Switched Access Service rates for all traffic passed without CPN unless the Parties agree that such other rates should apply to such traffic.

5.6.3 The Parties agree to provide a single statewide percent local usage ("PLU") factor for all traffic exchanged between the Parties directly and indirectly via a Tandem Transit provider. Each Party shall provide the initial PLU to the other within 30 days of execution of the Agreement. Adjustments to the applicable PLU, if any, may be made on a calendar-year quarterly basis, within 15 calendar days after the end of each quarter. When billing the other Party, a Party may classify traffic as either Local Traffic or IntraLATA Toll Traffic by using CPN information or such PLU factor.

5.7 Compensation Arrangements

Compensation arrangements address the transport and termination of Local Traffic and IntraLATA Toll Traffic between the Parties. Compensation for the transport and termination of traffic not specifically addressed in this subsection 5.7 shall be as provided elsewhere in this Agreement, or if not so provided, as required by the Tariffs of the Party transporting and/or terminating the traffic.

5.7.1 Nothing in this Agreement shall be construed to limit either Party's ability to designate the areas within which that Party's Customers may make calls which that Party rates as "local" in its Customer Tariffs.

For all Local Traffic, the Parties shall compensate each other for the transport and termination of all Local Traffic (including Internet Traffic) at the rates provided in the Detailed Schedule of Itemized Charges (Appendix 1 hereto).

No additional charges, including port or transport charges, shall apply for receiving and terminating Local Traffic or receiving and handing off Internet Traffic delivered to the Cox-POI or the Pac-West-POI, except as set forth in the Price Schedule.

The Parties agree to abide by all applicable orders and rules of the FCC and Commission with respect to Reciprocal Compensation for Local Traffic exchanged between the Parties, to the extent such orders and rules do not conflict with the Act.

The Parties shall compensate each other for the transport and termination of all IntraLATA Toll Traffic at the rates provided in the Detailed Schedule of Itemized Charges (Appendix 1 hereto).

The designation of traffic as Local or IntraLATA Toll for purposes of compensation shall be based on the horizontal and vertical coordinates associated with the originating and terminating NPA-NXXs of the call, regardless of the carrier(s) involved in carrying any segment of the call.

In accordance with subsection 14.2, Pac-West and Cox agree that all networks involved in exchanging Pac-West and Cox traffic via Tandem Transit arrangement will use CCS/SS7 protocol, including Calling Party Number ("CPN") and appropriate TCAP messages, to facilitate full interoperability and billing and/or self-audit functions.

5.7.8 Each Party reserves the right to measure and audit all traffic, up to a maximum of one audit per 12-month period, to ensure that proper rates are being applied appropriately, provided, however, that either Party shall have the right to conduct additional audit(s) if the preceding audit disclosed material errors or discrepancies. Each Party agrees to provide the necessary traffic data or permit the other Party's recording equipment to be installed for sampling purposes in conjunction with any such audit.

5.8 Compensation to Third Party Transit Tandem Service Providers

5.8.1 Where Traffic is exchanged via a third party's Tandem Transit arrangement, the originating Party shall be responsible for payment of any transit charges assessed by the third party Tandem Transit provider for the use of its tandem. Further, it is the originating Party's responsibility to ensure that any agreement it may have in place with such third party Tandem Transit provider allows the originating Party's traffic to be transited to the terminating Party.

5.8.2 To the extent required to prevent double payment or double recovery by either Party, if either Party bills the Tandem Transit provider for terminating the other Party's traffic, or if either Party pays the Tandem Transit provider to terminate that Party's traffic (in addition to paying the Tandem Transit provider's 'transit' charges), the Parties agree that no additional compensation for such traffic shall be billed or owed between the Parties.

6.0 800/888 TRAFFIC

For IntraLATA Toll Free Service calls provided by one of the Parties, the compensation set forth in the Detailed Schedule of Itemized Charges (Appendix 1 hereto) for IntraLATA Toll Traffic, shall be paid by the Party terminating the call to the Party originating the call. If needed, the Parties will develop a mutually agreed-to method for exchanging billing data for this purpose.

10.2 Installation, Maintenance, Testing and Repair

Unless otherwise agreed to by the Parties, direct Interconnection shall be equal in quality to that provided by each of the Parties to any subsidiary, affiliate, or third party. For purposes of this Agreement, "equal in quality" means the same or equivalent interface specifications, provisioning, installation, maintenance, testing and repair intervals for the same or equivalent services under like circumstances. If either Party is unable to fulfill its obligations under this subsection 10.2, it shall notify the other Party of its inability to do so and will negotiate alternative intervals in good faith. The Parties agree that the standards to be used by each Party for isolating and clearing any disconnections and/or other direct or indirect Interconnection outages or troubles shall be no less favorable than those applicable to comparable arrangements, facilities, or services being provided by such Party to any other carrier whose network is connected to that of the Providing Party.

10.3 Forecasting Requirements for Trunk Provisioning

10.3.1 Where direct Interconnection is used, within ninety (90) days of executing this Agreement, the Parties shall provide one another yearly traffic forecasts. This initial forecast will provide the amount of traffic to be delivered by each Party over each of the Interconnection Trunk groups. The forecast shall be updated and provided to one another twice a year. All forecasts shall include Access Carrier Terminal Location, traffic type (local/toll, IP, etc.), code (identifies trunk group), A location/Z location (CLLI codes), interface type (e.g., DS1), and cumulative trunks in service each year for current, as well as current plus-1 and plus-2 years.

10.3.2 Where direct Interconnection is used the Parties will, for ninety (90) days, monitor traffic on each trunk group that it establishes. At the end of such ninety (90) day period, either Party may request to disconnect trunks that, based on reasonable engineering criteria and capacity constraints, are not warranted by the actual traffic volume experienced.

11.0 LOCAL NUMBER PORTABILITY

11.1 Scope

The Parties shall provide Local Number Portability (LNP) in accordance with the Act and the rules and regulations as from time to time prescribed by the FCC. Location Routing Number (LRN) is currently being used by the telecommunications industry to provide LNP, and will be used by the Parties to implement LNP between their networks to the extent required under the Act and the FCC's regulations.

14.0 DATABASES AND SIGNALING

14.1 Each Party shall provide the other Party with access to databases and associated signaling necessary for call routing and completion, including but not limited to calling name information as required, by providing SS7 Common Channel Signaling (CCS) Interconnection in accordance with existing Tariffs, and Interconnection and access to 800/888 databases, LIDB, and any other necessary databases in accordance with existing Tariffs and/or agreements with other unaffiliated carriers, with compensation terms in accordance with Section 14.3 below. Alternatively, either Party may secure CCS Interconnection from a commercial SS7 hub provider, and in that case the other Party will permit the purchasing Party to access the same databases as would have been accessible if the purchasing party had connected directly to the other Party's CCS network.

14.2 The Parties will provide CCS Signaling to one another in all direct or indirect Interconnection trunking arrangements. The Parties will cooperate on the exchange of TCAP messages to facilitate interoperability of all CCS-based features and services, including but not limited to CLASS and Calling Name Delivery, to the extent each Party offers such features and functions to its Customers. All CCS Signaling parameters will be provided upon request (where such parameters are available and support signaling features and functions deployed within both Parties' networks), including called party number, Calling Party Number, calling party category, and charge number. All privacy indicators will be honored.

14.3 The Parties agree that their respective CCS signaling costs shall offset each other, and no explicit compensation between the Parties shall apply.

16.0 COORDINATION WITH TARIFF TERMS

16.1 Where explicitly noted in this Agreement, the Parties acknowledge that some of the services, facilities, and arrangements described herein are or will be available under and subject to the terms of the federal or state Tariffs of the other Party applicable to such services, facilities, and arrangements. To the extent a Tariff of the Providing Party applies to any service, facility, and arrangement described herein, the Parties agree as follows:

16.1.1 Those rates and charges for services, facilities, and arrangements that reference a rate contained in an existing Tariff of the Providing Party, shall conform with those contained in the then-prevailing Tariff and vary in accordance with any changes that may be made to the Tariff rates and charges subsequent to the Effective Date.

18.0 TERM AND TERMINATION.

18.1 This Agreement shall be effective as of the execution date first above written and continue in effect for one (1) year, and thereafter the Agreement shall continue in force and effect unless and until terminated as provided herein. Upon the expiration of the initial term, either Party may terminate this Agreement by providing written notice of termination to the other Party, such written notice to be provided at least ninety (90) days in advance of the date of termination. In the event of such termination, those service arrangements made available under this Agreement shall continue without interruption on a month-to-month basis until a new agreement is executed by the Parties.

18.2 If either Party defaults in the payment of any amount due hereunder, or if either Party violates any other provision of this Agreement, and such default or violation shall continue for thirty (30) days after written notice thereof, the other Party may terminate this Agreement and services hereunder by written notice; provided the other Party has provided the defaulting Party and the appropriate federal and/or state regulatory bodies with written notice at least twenty five (25) days prior to terminating service. Notice shall be posted by overnight mail, return receipt requested. If the defaulting Party cures the default or violation within the twenty five (25) day period, the other Party will not terminate service or this Agreement but shall be entitled to recover all costs, if any, incurred by it in connection with the default or violation, including, without limitation, costs incurred to prepare for the termination of service.

19.0 DISCLAIMER OF REPRESENTATIONS AND WARRANTIES

EXCEPT AS EXPRESSLY PROVIDED UNDER THIS AGREEMENT, NEITHER PARTY MAKES ANY WARRANTY, EXPRESS OR IMPLIED, WITH RESPECT TO THE SERVICES, FUNCTIONS AND PRODUCTS IT PROVIDES UNDER OR CONTEMPLATED BY THIS AGREEMENT AND THE PARTIES DISCLAIM THE IMPLIED WARRANTIES OF MERCHANTABILITY AND OF FITNESS FOR A PARTICULAR PURPOSE.

20.0 CANCELLATION CHARGES

Except as provided in this Agreement or as otherwise provided in any applicable Tariff, no cancellation charges shall apply.

21.0 INDEMNIFICATION

21.1 Each Party agrees to release, indemnify, defend and hold harmless the other Party from and against all losses, claims, demands, damages, expenses, suits or other actions, or any liability whatsoever, including, but not limited to, costs and attorneys' fees (collectively, a "Loss"), (a) whether suffered, made, instituted, or asserted by any other party or person, relating to personal injury to or death of any person, or for loss, damage to, or destruction of real and/or personal property, whether or not owned by others, incurred during the term of this Agreement and to the extent proximately caused by the acts or omissions of the indemnifying Party, regardless of the form of action, or (b) suffered, made, instituted, or asserted by its own Customer(s) against the other Party arising out of the other Party's provision of services to the indemnifying Party under this Agreement. Notwithstanding the foregoing indemnification, nothing in this Section 21. shall affect or limit any claims, remedies, or other actions the indemnifying Party may have against the indemnified Party under this Agreement, any other contract, or any applicable Tariff(s), regulations or laws for the indemnified Party's provision of said services.

21.2 The indemnification provided herein shall be conditioned upon:

(a) The indemnified Party shall promptly notify the indemnifying Party of any action taken against the indemnified Party relating to the indemnification.

(b) The indemnifying Party shall have sole authority to defend any such action, including the selection of legal counsel, and the indemnified Party may engage separate legal counsel only at its sole cost and expense.

(c) In no event shall the indemnifying Party settle or consent to any judgment pertaining to any such action without the prior written consent of the indemnified Party, which consent shall not be unreasonably withheld.

(d) The indemnified Party shall, in all cases, assert any and all provisions in its Tariffs that limit liability to third parties as a bar to any recovery by the third party claimant in excess of such limitation of liability.

(e) The indemnified Party shall offer the indemnifying Party all reasonable cooperation and assistance in the defense of any such action.

22.0 LIMITATION OF LIABILITY

22.1 The liability of either Party to the other Party for damages arising out of failure to comply with a direction to install, restore or terminate facilities; or out of failures, mistakes, omissions, interruptions, delays, errors, or defects occurring in the course of furnishing any services, arrangements, or facilities hereunder shall be determined in accordance with the terms of the applicable Tariff(s) of the Providing Party. In the event no Tariff(s) apply, the Providing Party's liability shall not exceed an amount equal to the pro rata monthly charge for the period in which such failures, mistakes, omissions, interruptions, delays, errors or defects occur. Recovery of said amount shall be the injured Party's sole and exclusive remedy against the Providing Party for such failures, mistakes, omissions, interruptions, delays, errors or defects.

22.2 Neither Party shall be liable to the other in connection with the provision or use of services offered under this Agreement for indirect, incidental, consequential, reliance or special damages, including (without limitation) damages for lost profits (collectively, "Consequential Damages"), regardless of the form of action, whether in contract, warranty, strict liability, or tort, including, without limitation, negligence of any kind, even if the other Party has been advised of the possibility of such damages; provided, that the foregoing shall not limit a Party's obligation under Section 21.

22.3 The Parties agree that neither Party shall be liable to the Customers of the other Party in connection with its provision of services to the other Party under this Agreement. Nothing in this Agreement shall be deemed to create a third party beneficiary relationship between the Party providing the service and the Customers of the Party purchasing the service. In the event of a dispute involving both Parties with a Customer of one Party, both Parties shall assert the applicability of any limitations on liability to Customers that may be contained in either Party's applicable Tariff(s).

23.0 COMPLIANCE WITH LAWS

23.1 Each Party represents and warrants that it is now and will remain in compliance with all Applicable Laws. Each Party shall promptly notify the other Party in writing of any governmental action that suspends, cancels, withdraws, limits, or otherwise materially affects its ability to perform its obligations hereunder.

23.2 The Parties recognize that the FCC has issued and may continue to issue the FCC regulations implementing of the Telecommunications Act that affect certain terms contained in this Agreement. In the event that any one or more of the provisions contained herein is inconsistent with any applicable rule contained in such FCC Regulations, the Parties agree to make only the minimum revisions necessary to eliminate the inconsistency or amend the application-affecting provision(s).

23.3 In the event any Applicable Law other than the FCC Regulations requires modification of any material term(s) contained in this Agreement or if any of the definitions that are expressly taken from the Act and restated in Section 1 hereof are amended in any material fashion, either Party may require a renegotiation of the term(s) that require direct modification as well as of any term(s) that are reasonably affected thereby. If neither Party requests a renegotiation or if an Applicable Law requires modification of any non-material term(s), then the Parties agree to make only the minimum modifications necessary, and the remaining provisions of this Agreement shall remain in full force and effect.

24.5 Choice of Law

The construction, interpretation and performance of this Agreement shall be governed by and construed in accordance with the laws of the State of California, except for its conflicts of laws provisions. In addition, insofar as and to the extent federal law may apply, federal law will control.

24.6 Taxes

24.6.1 In General. With respect to any purchase hereunder of services, facilities or arrangements, if any federal, state or local tax, fee, surcharge or other tax-like charge (a "Tax") is required or permitted by Applicable Law to be collected from the purchasing Party by the Providing Party, then (i) the Providing Party shall properly xxxx the purchasing Party for such Tax, (ii) the purchasing Party shall timely remit such Tax to the Providing Party and (iii) the Providing Party shall timely remit such collected Tax to the applicable taxing authority.

24.6.2 Taxes Imposed on the Providing Party With respect to any purchase hereunder of services, facilities or arrangements, if any federal, state or local Tax is imposed by Applicable Law on the receipts of the Providing Party, which Law permits the Providing Party to exclude certain receipts received from sales for resale to a public utility, distributor, telephone company, local exchange carrier, telecommunications company or other communications company ("Telecommunications Company"), such exclusion being based solely on the fact that the purchasing Party is also subject to a tax based upon receipts ("Receipts Tax"), then the purchasing Party (i) shall provide the Providing Party with notice in writing in accordance with subsection 24.6.6 of this Agreement of its intent to pay the Receipts Tax and (ii) shall timely pay the Receipts Tax to the applicable tax authority.

24.6.3 Taxes Imposed on Customers With respect to any purchase hereunder of services, facilities or arrangements that are resold to a third party, if any federal, state or local Tax is imposed by Applicable Law on the subscriber, end-user, Customer or ultimate consumer ("Subscriber") in connection with any such purchase, which a Telecommunications Company is required to impose and/or collect from a Subscriber, then the purchasing Party (i) shall be required to impose and/or collect such Tax from the Subscriber and (ii) shall timely remit such Tax to the applicable taxing authority.

24.6.4 Liability for Uncollected Tax, Interest and Penalty If the Providing Party has not received an exemption certificate and fails to collect any Tax as required by subsection 24.6.1, then, as between the Providing Party and the purchasing Party, (i) the purchasing Party shall remain liable for such uncollected Tax and (ii) the Providing Party shall be liable for any interest assessed thereon and any penalty assessed with respect to such uncollected Tax by such authority. If the Providing Party properly bills the purchasing Party for any Tax but the purchasing Party fails to remit such Tax to the Providing Party as required by subsection 24.6.1, then, as between the Providing Party and the purchasing Party, the purchasing Party shall be liable for such uncollected Tax and any interest assessed thereon, as well as any penalty assessed with respect to such uncollected Tax by the applicable taxing authority. If the Providing Party does not collect any Tax as required by subsection 24.6.1 because the purchasing Party has provided such Providing Party with an exemption certificate that is later found to be inadequate by a taxing authority, then, as between the Providing Party and the purchasing Party, the purchasing Party shall be liable for such uncollected Tax and any interest assessed thereon, as well as any penalty assessed with respect to such uncollected Tax by the applicable taxing authority. If the purchasing Party fails to pay the Receipts Tax as required by subsection 24.6.2, then, as between the Providing Party and the purchasing Party, (x) the Providing Party shall be liable for any Tax imposed on its receipts and (y) the purchasing Party shall be liable for any interest assessed thereon and any penalty assessed upon the Providing Party with respect to such Tax by such authority. If the purchasing Party fails to impose and/or collect any Tax from Subscribers as required by subsection 24.6.3, then, as between the Providing Party and the purchasing Party, the purchasing Party shall remain liable for such uncollected Tax and any interest assessed thereon, as well as any penalty assessed with respect to such uncollected Tax by the applicable taxing authority. With respect to any Tax that the purchasing Party has agreed to pay, or is required to impose on and/or collect from Subscribers, the purchasing Party agrees to indemnify and hold the Providing Party harmless on an after-tax basis for any costs incurred by the Providing Party as a result of actions taken by the applicable taxing authority to recover the Tax from the Providing Party due to the failure of the purchasing Party to timely pay, or collect and timely remit, such Tax to such authority. In the event either Party is audited by a taxing authority, the other Party agrees to cooperate fully with the Party being audited in order to respond to any audit inquiries in a proper and timely manner so that the audit and/or any resulting controversy may be resolved expeditiously.

24.6.5 Tax Exemptions and Exemption Certificates If Applicable Law clearly exempts a purchase hereunder from a Tax, and if such Law also provides an exemption procedure, such as an exemption-certificate requirement, then, if the purchasing Party complies with such procedure, the Providing Party shall not collect such Tax during the effective period of such exemption. Such exemption shall be effective upon receipt of the exemption certificate or affidavit in accordance with the terms set forth in subsection 24.6.6. If Applicable Law clearly exempts a purchase hereunder from a Tax, but does not also provide an exemption procedure, then the Providing Party shall not collect such Tax if the purchasing Party (i) furnishes the Providing Party with a letter signed by an officer requesting such an exemption and citing the provision in the Law which clearly allows such exemption and (ii) supplies the Providing Party with an indemnification agreement, reasonably acceptable to the Providing Party (e.g., an agreement commonly used in the industry), which holds the Providing Party harmless on an after-tax basis with respect to its forbearing to collect such Tax.

24.6.6 Notices for Purposes of this Subsection 24.6 All notices, affidavits, exemption-certificates or other communications required or permitted to be given by either Party to the other, for purposes of this subsection 24.6, shall be made in writing and shall be delivered in person or sent by certified mail, return receipt requested, or registered mail, or a courier service providing proof of service, and sent to the addressees set forth in subsection 24.10 as well as to the following:

To Pac-West:

Either Party may from time to time designate another address or other addressees by giving notice in accordance with the terms of this subsection 24.6. Any notice or other communication shall be deemed to be given when received.

24.7 Assignment.

Either Party may assign this Agreement or any of its rights or obligations hereunder to a third party, with the other Party's prior written consent, which consent shall not be unreasonably withheld upon the provision of reasonable evidence by the proposed assignee that it has the resources, ability, and authority to provide satisfactory performance under this Agreement. Any assignment or delegation in violation of this subsection 24.7 shall be void and ineffective and constitute a default of this Agreement. No consent will be required in the event of assignment to a parent owning a majority of the Party, or a majority owned subsidiary of the Party, provided that such assignment shall not relieve the assigning Party of its obligations hereunder unless otherwise agreed to by the Parties. The foregoing shall not be construed to prevent a Party from granting a security interest in this Agreement.

24.8 Billing and Payment; Disputed Amounts.

24.8.1 Except as may otherwise be provided in this Agreement, each Party shall submit on a monthly basis an itemized statement of charges incurred by the other Party during the preceding month(s) for services rendered hereunder. Payment of billed amounts under this Agreement, whether billed on a monthly basis or as otherwise provided herein, shall be due, in immediately available U.S. funds, within thirty (30) days of the date of such statement.

24.8.2 Although it is the intent of both Parties to submit timely and accurate statements of charges, failure by either Party to present statements to the other Party in a timely manner shall not constitute a breach or default, or a waiver of the right to payment of the incurred charges, by the billing Party under this Agreement, and the billed Party shall not be entitled to dispute the billing Party's statement(s) based on such Party's failure to submit them in a timely fashion.

24.8.3 No claims, under this Agreement or its Attachments, shall be brought for disputed amounts more than twenty-four (24) months from the date of occurrence which gives rise to the dispute. If any portion of an amount due to a Party (the "Billing Party") under this Agreement is subject to a bona fide dispute between the Parties, the Party billed (the "Non-Paying Party") shall within sixty (60) days of its receipt of the invoice containing such disputed amount give notice to the Billing Party of the amounts it disputes ("Disputed Amounts") and include in such notice the specific details and reasons for disputing each item. The Non-Paying Party shall pay when due (i) all undisputed amounts to the Billing Party and (ii) the Disputed Amount into an interest bearing escrow account with, or obtained from (in the case of a bond or letter of credit), an entity agreeable to both Parties. The Disputed Amount shall thereafter be paid, if appropriate, upon final determination of such dispute.

24.8.4 If the Parties are unable to resolve the issues related to the Disputed Amounts in the normal course of business within sixty (60) days after delivery to the Billing Party of notice of the Disputed Amounts, each of the Parties shall appoint a designated representative that has authority to settle the dispute and that is at a higher level of management than the persons with direct responsibility for administration of this Agreement. The designated representatives shall meet as often as they reasonably deem necessary in order to discuss the dispute and negotiate in good faith in an effort to resolve such dispute. The specific format for such discussions will be left to the discretion of the designated representatives, however all reasonable requests for relevant information made by one Party to the other Party shall be honored.

24.8.5 If the Parties are unable to resolve issues related to the Disputed Amounts within forty five (45) days after the Parties' appointment of designated representatives pursuant to subsection 24.8.4, or if either Party fails to appoint a designated representative within forty five (45) days, then either Party may file a complaint with the Commission to resolve such issues or proceed with any other remedy pursuant to law or equity. The Commission may direct release of any or all funds (including any accrued interest) in the escrow account, plus applicable late fees, to be paid to either Party.

24.8.6 The Parties agree that all negotiations pursuant to this subsection 24.8 shall remain confidential and shall be treated as compromise and settlement negotiations for purposes of the Federal Rules of Evidence and state rules of evidence.

24.8.7 Any undisputed amounts not paid when due shall accrue interest from the date such amounts were due at the lesser of (i) one and one-half percent (1-1/2%) per month or (ii) the highest rate of interest that may be charged under applicable law.

24.9 Dispute Resolution

Any dispute between the Parties regarding the interpretation or enforcement of this Agreement or any of its terms shall be addressed by good faith negotiation between the Parties, in the first instance. Should such negotiations fail to resolve the dispute in a reasonable time, the Parties may, upon mutual agreement, submit the matter to alternative dispute resolution ("ADR") or, in the absence of such an agreement, either Party may initiate an appropriate action in any regulatory or judicial forum of competent jurisdiction.

24.10 Notices

Except as otherwise provided in this Agreement, notices given by one Party to the other Party under this Agreement shall be in writing and shall be (a) delivered personally, (b) delivered by express delivery service, or (c) mailed, certified mail or first class U.S. mail postage prepaid, return receipt requested, to the following addresses of the Parties:

24.12 No Third Party Beneficiaries; Disclaimer of Agency

This Agreement is for the sole benefit of the Parties and their permitted assigns, and nothing herein express or implied shall create or be construed to create any third-party beneficiary rights hereunder. Except for provisions herein expressly authorizing a Party to act for another, nothing in this Agreement shall constitute a Party as a legal representative or agent of the other Party, nor shall a Party have the right or authority to assume, create or incur any liability or any obligation of any kind, express or implied, against or in the name or on behalf of the other Party unless otherwise expressly permitted by such other Party. Except as otherwise expressly provided in this Agreement, no Party undertakes to perform any obligation of the other Party, whether regulatory or contractual, or to assume any responsibility for the management of the other Party's business.

24.13 No License

24.13.1 Nothing in this Agreement shall be construed as the grant of a license, either express or implied, with respect to any patent, copyright, trademark, trade name, trade secret or any other proprietary or intellectual property now or hereafter owned, controlled or licensable by either Party. Neither Party may use any patent, copyrightable materials, trademark, trade name, trade secret or other intellectual property right of the other Party except in accordance with the terms of a separate license agreement between the Parties granting such rights.

24.13.2 Neither Party shall have any obligation to defend, indemnify or hold harmless, or acquire any license or right for the benefit of, or owe any other obligation or have any liability to, the other Party or its Customers based on or arising from any claim, demand, or proceeding by any third party alleging or asserting that the use of any circuit, apparatus, or system, or the use of any software, or the performance of any service or method, or the provision of any facilities by either Party under this Agreement, alone or in combination with that of the other Party, constitutes direct, vicarious or contributory infringement or inducement to infringe, misuse or misappropriation of any patent, copyright, trademark, trade secret, or any other proprietary or intellectual property right of any Party or third party. Each Party, however, shall offer to the other reasonable cooperation and assistance in the defense of any such claim.

24.13.3 NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT, THE PARTIES AGREE THAT NEITHER PARTY HAS MADE, AND THAT THERE DOES NOT EXIST, ANY WARRANTY, EXPRESS OR IMPLIED, THAT THE USE BY THE PARTIES OF THE OTHER'S FACILITIES, ARRANGEMENTS, OR SERVICES PROVIDED UNDER THIS AGREEMENT SHALL NOT GIVE RISE TO A CLAIM BY ANY THIRD PARTY OF INFRINGEMENT, MISUSE, OR MISAPPROPRIATION OF ANY INTELLECTUAL PROPERTY RIGHT OF SUCH THIRD PARTY.

24.14 Technology Upgrades

Nothing in this Agreement shall limit either Party's ability to upgrade its network through the incorporation of new equipment, new software or otherwise. A Party shall provide the other written notice at least ninety (90) days prior to the incorporation of any such upgrades in its network that will materially affect the other's service, and shall exercise reasonable efforts to provide at least one hundred eighty (180) days' notice where practicable. The party receiving such notice shall be solely responsible for the cost and effort of accommodating such changes in its own network.

24.15 Survival

The Parties' obligations under this Agreement which by their nature are intended to continue beyond the termination or expiration of this Agreement shall survive the termination or expiration of this Agreement.

24.16 Entire Agreement

The terms contained in this Agreement and any Schedules, Appendices, Tariffs and other documents or instruments referred to herein, which are incorporated into this Agreement by this reference, constitute the entire agreement between the Parties with respect to the subject matter hereof, superseding all prior understandings, proposals and other communications, oral or written. Neither Party shall be bound by any preprinted terms additional to or different from those in this Agreement that may appear subsequently in the other Party's form documents, purchase orders, quotations, acknowledgments, invoices or other communications.

24.17 Counterparts

This Agreement may be executed in two or more counterparts, each of which shall be deemed an original and all of which together shall constitute one and the same instrument.

INITIAL INTERCONNECTION ARRANGEMENTS

1. Direct Interconnection. Where, and to the extent sound engineering practice suggests the use of direct interconnection, the Parties agree to establish such direct interconnection between their networks as described below:

(a) [If an ILEC 'cage-to-cage' interface is used.] Pac-West and Cox will implement a Mid-Span Meet interconnection. Cox will provide Pac-West Channel Facility Assignment and Letter Of Agency ("LOA") for a DS3 position on their APOT. Pac-West will order the DS3 cross connect from The ILEC (where The ILEC provides such cross connects) and will xxxx Xxx for its proportionate use of the recurring and non-recurring costs charged by The ILEC for the cross connect. Once Pac-West receives the Design Layout Record ("DLR")/Circuit Layout Record ("CLR"), the DLR/CLR will be forwarded to Cox with the proposed date of DS3 testing. After the DS3 cross connect is tested per Section 3 of this Appendix 2, then trunk interconnection will be established per section 4 of this Appendix 2.The applicable ACLLI will be ______________ and the ZCLLI will be ______________.

(b) [If a leased interface is used.] Pac-West and Cox will implement direct interconnection using ________ as the Local Access Provider. Cox will purchase the interoffice facilities from _______ and xxxx Pac-West for its proportionate use of the recurring and non-recurring costs charged by _______ for the facility. Pac-West will provide Cox with a LOA authorizing Cox to use the _______ entrance facilities at the Pac-West wire center to interconnect to the Pac-West network at the DS3 level. Once Cox receives the LOA, Cox shall submit a DS3 order to _______ with a standard interval due date. Once Cox receives the DLR/CLR, the DLR/CLR will be forwarded to Pac-West with the proposed date of DS3 testing. After the DS3 is tested per Section 3 of Appendix 1, then trunk interconnection will be established per section 4 of Appendix 2. The ACLLI will be ______________ and the ZCLLI will be ______________.

3. Testing. The Parties will coordinate with each other to test the DS-3 and/or DS-1s in accordance with standard industry practices. The DS-3 test will be for a period of seventy-two (72) hours to verify continuity.

4. Initial Trunking Requirements. Once testing is successfully completed, Pac-West and Cox will initially jointly engineer and provision two-way trunks, starting at channel 1 of the DS-3 or DS-1, into their respective switches for establishment of interconnection trunking. Pac-West will order the trunks from Cox using Access Service Request ("ASR") Exchange, which is ASOG ASR compliant to version 21. The trunk groups established pursuant to this MOU will be used to exchange Local Traffic (including traffic destined for Internet Service Providers) and IntraLATA Toll Traffic only.

(a) The trunking will be established using the following parameters:

Traffic Class: PH

Traffic Type: Local Direct End Office Trunking or Toll Direct End Office Trunking

Signaling/Coding: SS7/B8ZS/ESF

Direction: Two Way

Pac-West Xxxx: Most Idle

Cox Xxxx: Most Idle or Anti-Clockwise

Glare: ODD/EVEN

Quantity of Trunks: To be jointly determined based on sound engineering practices.

TCIC Range: To be determined based on mutually agreed-to trunk quantities.

Pac-West DPC: 206157001

Pac-West Switch CLLI: PHNAAZIADS1

Pac-West OCN: 2821 for Arizona

Pac-West CIC: 0099

Cox DPC: _______________________

Cox Switch CLLI: _______________________

Cox OCN: ___________________________

Cox CIC: ___________________________

5. Signaling. The Parties will provide CCS Signaling to one another in all direct or indirect Interconnection trunking arrangements. The Parties will cooperate on the exchange of TCAP messages to facilitate interoperability of all CCS-based features and services, including but not limited to CLASS and Calling Name Delivery, to the extent each Party offers such features and functions to its Customers. All CCS Signaling parameters will be provided upon request (where such parameters are available and support signaling features and functions deployed within both Parties' networks), including called party number, Calling Party Number, calling party category, and charge number. All privacy indicators will be honored.
