Line Sharing. 4.1 ‘Line Sharing’ is an arrangement by which Verizon facilitates ICG’s Rhythms’ provision of ADSL (in accordance with T1.413), Splitterless ADSL (in accordance with T1.419), RADSL (in accordance with TR # 59), Multiple Virtual Line (MVL (a proprietary technology)), or any other xDSL technology that is presumed to be acceptable for shared line deployment in accordance with FCC rules, to a particular Customer location over an existing copper Loop that is being used simultaneously by Verizon to provide analog circuit-switched voice grade service to that Customer by making available to ICGRhythms, solely for ICG’s Rhythms’ own use, the frequency range above the voice band on the same copper Loop required by ICG Rhythms to provide such services. This Section 4 Agreement addresses Line Sharing line sharing over loops that are entirely copper loops.. The Parties do not intend anything in this Agreement to prejudice Rhythms’ position that line sharing may occur on loops constructed of fiber optic cable, digital loop carrier electronics, and copper distribution cable.. 4.2 In accordance with, but only to To the extent required by Applicable Law, Verizon shall provide Line Sharing to ICG Rhythms for ICG’s Rhythms’ provision of ADSL (in accordance with T1.413), Splitterless ADSL (in accordance with T1.419), RADSL (in accordance with TR # 59), MVL (a proprietary technology), or any other xDSL technology that is presumed to be acceptable for shared line deployment in accordance with FCC rules, on the terms and conditions set forth herein. In order for a Loop to be eligible for Line Sharing, the following conditions must be satisfied for the duration of the Line Sharing arrangement: (i) the Loop must consist of a copper loop compatible with an xDSL service that is presumed to be acceptable for shared-line deployment in accordance with FCC rules; (ii) Verizon must be providing simultaneous circuit-switched analog voice grade service to the Customer served by the Loop in question; (iii) the Verizon Customer’s dial tone must originate from a Verizon End Office Switch in the Wire Center where the Line Sharing arrangement is being requested; and (iv) the xDSL technology to be deployed by ICG CLEC on that Loop must not significantly degrade the performance of other services provided on that Loop. 4.3 Verizon shall make Line Sharing available to ICG Rhythms at the rates set forth in Appendix A. These rates and/or rate structures shall be considered interim in nature until they have been approved by the Pricing AttachmentCommission or otherwise allowed to go into effect as a result of a proceeding before the Commission, whether initiated by Rhythms or Verizon, in which Rhythms is offered an opportunity to serve discovery and cross examine witnesses on the methodology and assumptions supporting Verizon’s proposed rates and rate structures, including a tariff investigation, cost proceeding, arbitration or other evidentiary proceeding. If, as a result of any such proceeding, the Commission should approve (or otherwise allow to go into effect) permanent rates and/or rate structures different than those shown in Appendix A, all such approved or effective permanent rates and/or rate structures shall supercede those shown in Appendix A. The permanent rates shall be effective retroactively to the effective date of the agreement.. The Parties shall true-up any amounts previously invoiced as if the permanent rates had been in effect as of that date. Each Party shall invoice the other for any amounts due to it as a result of such true-up, and all such invoices shall be paid in accordance with the Billing and Payment provisions of this Agreement 4.4 In addition to the recurring and nonrecurring charges shown in the Pricing Attachment Appendix A for Line Sharing itself, the following rates shown in the Pricing Attachment Appendix A and in Verizon Verizon’s applicable Tariffs are among those that may apply to a Line Sharing arrangement: (i) prequalification charges to determine whether a Loop is xDSL compatible (i.e., compatible with an xDSL service that is presumed to be acceptable for shared-line deployment in accordance with FCC rules); (ii) engineering query charges, engineering work order charges, or Loop conditioning (Digital Designed Loop) charges; (iii) charges associated with Collocation activities requested by ICGRhythms and not covered by Appendix A; and (iv) misdirected dispatch charges, charges for installation or repair, manual intervention surcharges, and trouble isolation charges, and pair swap/line and station transfer charges. 4.4 4.5 The following ordering procedures shall apply to Line Sharing: 4.4.1 4.5.1 To determine whether a Loop qualifies for Line Sharing, the Loop must first be prequalified to determine if it is xDSL compatible. ICG Rhythms must utilize the mechanized or and manual Loop qualification processes described in the terms applicable to xDSL and Digital Designed Loops Loops, as referenced in Section 4.5.5. below, to make this determination. 4.4.2 ICG 4.5.2 Rhythms shall place orders for Line Sharing by delivering to Verizon a valid electronic transmittal service order or other mutually agreed upon type of service order. Such service order shall be provided in accordance with industry format and specifications or such format and specifications as may be agreed to by the Parties. 4.4.3 4.5.3 If the Loop is prequalified by ICG Rhythms through the Loop prequalification database, and if a positive response is received and followed by receipt of ICG’s Rhythms’ valid, accurate and pre-qualified service order for Line Sharing, Verizon will return an a LSR confirmation within twenty-fourfour (24) hours (weekends and holidays excluded). 4.5.4 If the Loop requires qualification manually or through an Engineering Query, three (3) additional Business Days will be generally be required to obtain Loop qualification results before a LSR confirmation can be returned following receipt of Rhythms’ valid, accurate request. Verizon may in good faith require additional time to complete the Engineering Query where there are poor record conditions, spikes in demand, or other unforeseen events. Nonetheless, Xxxxxxx’s performance will be subject to the carrier-to-carrier performance standards established for Engineering Queries. 4.5.5 If conditioning is required to make a Loop capable of supporting Line Sharing and Rhythms orders such conditioning, then Verizon shall provide such conditioning in accordance with the terms of this Agreement pertaining to Digital Designed Loops; or if this Agreement does not contain provisions pertaining to Digital Designed Loops, then in accordance with Verizon’s generally available rates, terms and conditions applicable to Digital Design Loops; provided, however, that Verizon shall not be obligated to provide Loop conditioning if Verizon establishes that such conditioning is likely to degrade significantly the voice-grade service being provided to Verizon’s Customers over such Loops. 4.5.6 The standard provisioning interval for Line Sharing shall be three (3) Business Days. This interval is initiated once the required pre- qualification has been completed. The standard Loop provisioning and installation process will be initiated for Line Sharing only once the requested engineering and conditioning tasks have been completed on the Loop. For example, Pair Swaps or Line Station Transfers will require no less than an additional three (3) Business Days to complete. Scheduling changes and charges associated with order cancellations after conditioning work has been initiated are addressed in the terms pertaining to Digital Designed Loops, as referenced in Section 4.5.5. above. In no event shall the Line Sharing interval applied to Rhythms be longer than the interval applied to any Affiliate of Verizon. 4.5.7 A Pair Swap or Line and Station Transfer done in conjunction with a Line Share Arrangement request involves the reassignment and relocation of an existing Verizon end user voice service from a Digital Loop Carrier ("DLC") facility that is not qualified for line sharing to a spare or freed-up qualified non-loaded copper facility. (A freed-up pair is a qualified, copper pair already assigned.) Such a swap or transfer would be done in order to support the requested service transmission parameters. This new process will be applied to all cases where Verizon encounters the customer on DLC and where Verizon can automatically reassign the customer to a spare copper facility. This effort involves additional installation work including a dispatch and will require an additional charge. Rhythms acknowledges, however that the rate for such charge is not set forth in Appendix A as of the Effective Date, but that Verizon is developing such rate. Verizon shall notify Rhythms in writing of such Rate in accordance with, and subject to, the notices provision of the Interconnection Agreement. 4.5.8 Rhythms must provide all required Collocation, CFA, SBN and NC/NCI information when a Line Sharing Arrangement is ordered. Collocation augments required, either at the POT Bay, Collocation node, or for splitter placement must be ordered using standard collocation applications and procedures, unless otherwise agreed to by the parties or specified in this agreement, such as in section 4.7 4.5.9 The Parties will make reasonable efforts to coordinate their respective roles in order to minimize provisioning problems and facility issues. Rhythms will provide reasonable, timely, and accurate forecasts of its Line Sharing requirements, including splitter placement elections and ordering preferences. These forecasts are in addition to projections provided for other stand-alone unbundled Loop types. 4.6 To the extent required by Applicable Law, Rhythms shall provide Verizon with information regarding the type of xDSL technology that it deploys on each shared Loop. Where any proposed change in technology is planned on a shared Loop, Rhythms must provide this information to Verizon in order for Verizon to update Loop records and anticipate effects that the change may have on the voice grade service and other Loops in the same or adjacent binder groups. As described more fully in Verizon Technical Reference 72575, the xDSL technology used by Rhythms for Line Share Arrangements shall operate within the Power Spectral Density (PSD) limits set forth in T1.413-1998 (ADSL), T1.419-2000 (Splitterless ADSL), or TR59-1999 (RADSL), and MVL (a proprietary technology) shall operate within the 0 to 4 kHz PSD limits of T1.413-1998 and within the transmit PSD limits of T1.601-1998 for frequencies above 4 kHz, provided that the MVL PSD associated with audible frequencies above 4 kHz shall be sufficiently attenuated to preclude significantly degrading voice services. Rhythms’ deployment of additional Advanced Services shall be subject to the applicable rules and regulations of the FCC. 4.7 Rhythms may only access the high frequency portion of a Loop in a Line Sharing arrangement through an established Collocation arrangement at the Verizon Serving Wire Center that contains the End Office Switch through which voice grade service is provided to Verizon’s Customer. Rhythms is responsible for providing a splitter at that Wire Center that complies with ANSI specification T1.413 through one of the splitter options described below. (The Siecor splitter proposed for use by Rhythms as of May 12, 2000 is deemed by both Parties to be compliant with ANSI T1.413.) Rhythms is also responsible for providing its own DSLAM equipment in the Collocation arrangement and any necessary CPE for the xDSL service it intends to provide (including CPE splitters, filters and/or

Such service order Service Order shall be provided in accordance with industry format and specifications or such format and specifications as may be agreed to by the Parties. 4.4.3 If the Loop is prequalified by ICG Advent through the Verizon Loop prequalification databasetools, and if a positive response is received and followed by receipt of ICGAdvent’s valid, accurate and pre-qualified service order Service Order for Line Sharing, Verizon will return an LSR confirmation within twenty-fourfour (24) hours (weekends and holidays excluded) for LSRs with less than six (6) loops and within 72 hours (weekends and holidays excluded) for LSRs with six (6) or more loops. In such case, Verizon shall initiate provisioning and installation in accordance with the terms pertaining to xDSL Compatible Loops, Digital Designed Loops and Conditioned Loops pursuant to Section 3.2.5 of this Attachment. 4.4.4 If the Loop requires qualification manually or through an Engineering Query, three (3) additional Business Days will generally be required to obtain Loop qualification results before an order confirmation can be returned following receipt of Advent’s valid, accurate request. Verizon may require additional time to complete the Engineering Query where there are poor record conditions, spikes in demand, or other unforeseen events. 4.4.5 If conditioning is required to make a Loop capable of supporting Line Sharing and Advent orders such conditioning, then Verizon shall provide such conditioning in accordance with the terms of this Agreement pertaining to Digital Designed or Conditioned Loops;‌ provided, however, that Verizon shall not be obligated to provide Loop conditioning if Verizon establishes, in the manner required by Applicable Law, that such conditioning is likely to degrade significantly the Voice-Grade service being provided to Verizon’s Customers over such Loops. 4.4.6 The standard Loop provisioning and installation process will be initiated for the Line Sharing arrangement only once the requested engineering and conditioning tasks have been completed on the Loop. Scheduling changes and charges associated with order cancellations after conditioning work has been initiated are addressed in the terms pertaining to Digital Designed and Conditioned Loops, as referenced in Section 4.4.5 of this Attachment. The standard provisioning interval for the Line Sharing arrangement shall be as set out in the Verizon Product Interval Guide; provided that the standard provisioning interval for the Line Sharing arrangement shall not exceed the shortest of the following intervals: (a) six (6) Business Days; (b) the standard provisioning interval for the Line Sharing arrangement that is stated in an applicable Verizon Tariff; or, (c) the standard provisioning interval for the Line Sharing arrangement that is required by Applicable Law, if any. The standard provisioning interval for the Line Sharing arrangement shall commence only once any requested engineering and conditioning tasks have been completed. The standard provisioning interval shall not apply where a Line and Station Transfer is performed pursuant to Section 3.2.5.2. In no event shall the Line Sharing interval offered to Advent be longer than the interval offered to any similarly situated Affiliate of Verizon. 4.4.7 Advent must provide all required Collocation, CFA, Special Xxxx Number (SBN) and NC/NCI information when a Line Sharing Arrangement is ordered. Collocation augments required, either at the Point of Termination (POT) Bay, Collocation node, or for splitter placement, must be ordered using standard Collocation applications and procedures, unless otherwise agreed to by the Parties or specified in this Agreement. 4.4.8 The Parties recognize that Line Sharing is an offering that requires both Parties to make reasonable efforts to coordinate their respective roles in order to minimize provisioning problems and facility issues. Advent will provide reasonable, timely, and accurate forecasts of its Line Sharing requirements, including splitter placement elections and ordering preferences. These forecasts are in addition to projections provided for other stand-alone unbundled Loop types. 4.5 To the extent required by Applicable Law, Advent shall provide Verizon with information regarding the type of xDSL technology that it deploys on each shared Loop. Where any proposed change in technology is planned on a shared Loop, Advent must provide this information to Verizon in order for Verizon to update Loop records and anticipate effects that the change may have on the Voice Grade service and other Loops in the same or adjacent binder groups. 4.6 As described more fully in Verizon Technical Reference 72575, the xDSL technology used by Advent for Line Share Arrangements shall operate within the Power Spectral Density (PSD) limits set forth in T1.413-1998 (ADSL), T1.419- 2000 (Splitterless ADSL), or TR59-1999 (RADSL), and MVL (a proprietary technology) shall operate within the 0 to 4 kHz PSD limits of T1.413-1998 and within the transmit PSD limits of T1.601-1998 for frequencies above 4 kHz, provided that the MVL PSD associated with audible frequencies above 4 kHz shall be sufficiently attenuated to preclude significantly degrading voice services. Advent’s deployment of additional Advanced Services shall be subject to the applicable FCC Regulations. 4.7 Advent may only access the high frequency portion of a Loop in a Line Sharing arrangement through an established Collocation arrangement at the Verizon Serving Wire Center that contains the End Office Switch through which Voice Grade service is provided to Verizon’s Customer. Advent is responsible for providing, through one of the splitter options described below, a splitter at that Wire Center that complies with ANSI specification T1.413, employs Direct Current (DC) blocking capacitors or equivalent technology to assist in isolating high bandwidth trouble resolution and maintenance to the high frequency portion of the frequency spectrum, and operates so that the analog voice "dial tone" stays active when the splitter card is removed for testing or maintenance. Advent is also responsible for providing its own Digital Subscriber Line Access Multiplexer (DSLAM) equipment in the Collocation arrangement and any necessary Customer Provided Equipment (CPE) for the xDSL service it intends to provide (including CPE splitters, filters and/or other equipment necessary for the end user to receive separate voice and data services across the shared Loop). Two splitter configurations are available. In both configurations, the splitter must be provided by Advent and must satisfy the same NEBS requirements that Verizon imposes on its own splitter equipment or the splitter equipment of any Verizon Affiliate. Advent must designate which splitter option it is choosing on the Collocation application or augment. Regardless of the option selected, the splitter arrangements must be installed before Advent submits an order for Line Sharing. Splitter Option A (Splitter Option 1): Splitter in Advent Collocation Area In this configuration, the Advent-provided splitter (ANSI T1.413 or MVL compliant) is provided, installed and maintained by Advent in its own Collocation space within the Customer’s serving End Office. The Verizon-provided dial tone is routed through the splitter in the Advent Collocation area. Any rearrangements will be the responsibility of Advent. Splitter Option C (Splitter Option 2): Splitter in Verizon Area In this configuration, Verizon inventories and maintains a Advent-provided splitter (ANSI T1.413 or MVL compliant) in Verizon space within the Customer’s serving End Office. The splitters will be installed shelf-at-a-time. In those serving End Offices where Verizon employs the use of a POT Bay for interconnection of Advent’s Collocation arrangement with Verizon’s network, the splitter will be installed (mounted) in a relay rack between the POT Bay and the MDF. The demarcation point is at the splitter end of the cable connecting the POT Bay and the splitter. Installation of the splitter will be performed by Verizon or, at Advent’s election, by a Verizon-approved vendor designated by Advent. In those serving End Offices where Verizon does not employ a POT Bay for interconnection of Advent’s Collocation arrangement with Verizon’s network, the Advent provided splitter will be installed (mounted) in a relay rack between the Advent Collocation arrangement and the MDF. The demarcation point is at the splitter end of the cable connecting the Advent Collocation arrangement and the splitter. Installation of the splitter will be performed by Verizon, or, at Advent’s election, by a Verizon-approved vendor designated by Advent. In either scenario, Verizon will control the splitter and will direct any required activity. Where a POT Bay is employed, Verizon will also perform all POT Bay work required in this configuration. Verizon will provide a splitter inventory to Advent upon completion of the required work. 4.7.1 Where a new splitter is to be installed as part of an initial Collocation implementation, the splitter installation may be ordered as part of the initial Collocation application. Associated Collocation charges (application and engineering fees) apply. Advent must submit a new Collocation application, with the application fee, to Verizon detailing its request. Except as otherwise required by Applicable Law, standard Collocation intervals will apply. 4.7.2 Where a new splitter is to be installed as part of an existing Collocation arrangement, or where the existing Collocation arrangement is to be augmented (e.g., with additional terminations at the POT Bay or Advent’s Collocation arrangement to support Line Sharing), the splitter installation or augment may be ordered via an application for Collocation augment. Associated Collocation charges (application and engineering fees) apply. Advent must submit the application for Collocation augment, with the application fee, to Verizon. Unless a longer interval is stated in Verizon’s applicable Tariff, an interval of seventy-six (76) Business Days shall apply. 4.8 Advent will have the following options for testing shared Loops: 4.8.1 In serving End Offices where Verizon employs a POT Bay for interconnection of Advent Collocation arrangement with Verizon’s network, the following options shall be available to Advent. 4.8.1.1 Under Splitter Option A, Advent may conduct its own physical tests of the shared Loop from Advent’s Collocation area. If it chooses to do so, Advent may supply and install a test head to facilitate such physical tests, provided that: (a) the test head satisfies the same NEBS requirements that Verizon imposes on its own test head equipment or the test head equipment of any Verizon Affiliate; and (b) the test head does not interrupt the voice circuit to any greater degree than a conventional MLT test. Specifically, the Advent-provided test equipment may not interrupt an in-in- progress voice connection and must automatically restore any circuits tested in intervals comparable to MLT. This optional Advent-provided test head will be installed in Advent’s Collocation area between the “line” port of the splitter and the POT Bay in order to conduct remote physical tests of the shared Loop. 4.8.1.2 Under Splitter Option C, upon request by Advent, either Verizon or, at Advent’s election, a Verizon-approved vendor selected by Advent will install a Advent-provided test head to enable Advent to conduct remote physical tests of the

Line Sharing. 4.1 ‘“Line Sharing’ ” is an arrangement by which Verizon facilitates ICGBudget Phone’s provision of ADSL (in accordance with T1.413), Splitterless ADSL (in accordance with T1.419), RADSL (in accordance with TR # 59), Multiple Virtual Line (MVL MVL) (a proprietary technology)), or any other xDSL technology that is presumed to be acceptable for shared line deployment in accordance with FCC rules, to a particular Customer location over an existing copper Loop that is being used simultaneously by Verizon to provide analog circuit-switched voice grade service to that Customer by making available to ICGBudget Phone, solely for ICGBudget Phone’s own use, the frequency range above the voice band on the same copper Loop required by ICG Budget Phone to provide such services. This Section 4 addresses Line Sharing line sharing over loops that are entirely copper loops. 4.2 In accordance with, but only Subject to the extent required by Applicable Lawconditions set forth in Section 1, Verizon shall provide Line Sharing to ICG Budget Phone for ICGBudget Phone’s provision of ADSL (in accordance with T1.413), Splitterless ADSL (in accordance with T1.419), RADSL (in accordance with TR # 59), MVL (a proprietary technology), or any other xDSL technology that is presumed to be acceptable for shared line deployment in accordance with FCC rules, on in accordance with this Section 4 and the terms rates and conditions set forth hereincharges provided in the Pricing Attachment. Verizon shall provide Line Sharing to Budget Phone in accordance with, but only to the extent required by, Applicable Law. In order for a Loop to be eligible for Line Sharing, the following conditions must be satisfied for the duration of the Line Sharing arrangement: (i) the Loop must consist of a copper loop compatible with an xDSL service that is presumed to be acceptable for shared-line deployment in accordance with FCC rules; (ii) Verizon must be providing simultaneous circuit-switched analog voice grade service to the Customer served by the Loop in question; (iii) the Verizon Customer’s dial tone must originate from a Verizon End Office Switch in the Wire Center where the Line Sharing arrangement is being requested; and (iv) the xDSL technology to be deployed by ICG Budget Phone on that Loop must not significantly degrade the performance of other services provided on that Loop. 4.3 Verizon shall make Line Sharing available to ICG Budget Phone at the rates and charges set forth in the Pricing Attachment. In addition to the recurring and nonrecurring charges shown in the Pricing Attachment for Line Sharing itself, the following rates shown in the Pricing Attachment and in Verizon Verizon’s applicable Tariffs are among those that may apply to a Line Sharing arrangement: (i) prequalification charges to determine whether a Loop is xDSL compatible (i.e., compatible with an xDSL service that is presumed to be acceptable for shared-shared- line deployment in accordance with FCC rules); (ii) engineering query charges, engineering work order charges, or Loop conditioning (Digital Designed Loop) charges; (iii) charges associated with Collocation activities requested by ICGBudget Phone; and (iv) misdirected dispatch charges, charges for installation or repair, manual intervention surcharges, trouble isolation charges, and pair swap/line and station transfer charges. 4.4 The following ordering procedures shall apply to Line Sharing: 4.4.1 To determine whether a Loop qualifies for Line Sharing, the Loop must first be prequalified to determine if it is xDSL compatible. ICG Budget Phone must utilize the mechanized or manual Loop qualification processes described in the terms applicable to xDSL and Digital Designed Loops to make this determination. 4.4.2 ICG Budget Phone shall place orders for Line Sharing by delivering to Verizon a valid electronic transmittal service order or other mutually agreed upon type of service order. Such service order shall be provided in accordance with industry format and specifications or such format and specifications as may be agreed to by the Parties. 4.4.3 If the Loop is prequalified by ICG Budget Phone through the Loop prequalification database, and if a positive response is received and followed by receipt of ICGBudget Phone’s valid, accurate and pre-qualified service order for Line Sharing, Verizon will return an LSR confirmation within twenty-fourfour (24) hours (weekends and holidays excluded) for LSRs with less than six (6) loops and within 72 hours (weekends and holidays excluded) for LSRs with six (6) or more loops. 4.4.4 If the Loop requires qualification manually or through an Engineering Query, three (3) additional Business Days will generally be required to obtain Loop qualification results before an order confirmation can be returned following receipt of Budget Phone’s valid, accurate request. Verizon may require additional time to complete the Engineering Query where there are poor record conditions, spikes in demand, or other unforeseen events. 4.4.5 If conditioning is required to make a Loop capable of supporting Line Sharing and Budget Phone orders such conditioning, then Verizon shall provide such conditioning in accordance with the terms of this Agreement pertaining to Digital Designed Loops; or if this Agreement does not contain provisions pertaining to Digital Designed Loops, then in accordance with Verizon’s generally available rates, terms and conditions applicable to Digital Design Loops; provided, however, that Verizon shall not be obligated to provide Loop conditioning if Verizon establishes, in the manner required by Applicable Law, that such conditioning is likely to degrade significantly the voice-grade service being provided to Verizon’s Customers over such Loops. 4.4.6 The standard Loop provisioning and installation process will be initiated for the Line Sharing arrangement only once the requested engineering and conditioning tasks have been completed on the Loop. Scheduling changes and charges associated with order cancellations after conditioning work has been initiated are addressed in the terms pertaining to Digital Designed Loops, as referenced in Section 4.4.5, above. The standard provisioning interval for the Line Sharing arrangement shall be as set out in the Verizon Product Interval Guide; provided that the standard provisioning interval for the Line Sharing arrangement shall not exceed the shortest of the following intervals: (a) six (6) Business Days; (b) the standard provisioning interval for the Line Sharing arrangement that is stated in an applicable Verizon Tariff; or, (c) the standard provisioning interval for the Line Sharing arrangement that is required by Applicable Law. The standard provisioning interval for the Line Sharing arrangement shall commence only once any requested engineering and conditioning tasks have been completed. Line Sharing arrangements that require pair swaps or line and station transfers in order to free-up facilities may have a provisioning interval that is longer than the standard provisioning interval for the Line Sharing arrangement. In no event shall the Line Sharing interval offered to Budget Phone be longer than the interval offered to any similarly situated Affiliate of Verizon. 4.4.7 Budget Phone must provide all required Collocation, CFA, Special Xxxx Number (SBN) and NC/NCI information when a Line Sharing Arrangement is ordered. Collocation augments required, either at the Point of Termination (POT) Bay, Collocation node, or for splitter placement, must be ordered using standard collocation applications and procedures, unless otherwise agreed to by the Parties or specified in this Agreement. 4.4.8 The Parties recognize that Line Sharing is an offering that requires both Parties to make reasonable efforts to coordinate their respective roles in order to minimize provisioning problems and facility issues. Budget Phone will provide reasonable, timely, and accurate forecasts of its Line Sharing requirements, including splitter placement elections and ordering preferences. These forecasts are in addition to projections provided for other stand-alone unbundled Loop types. 4.5 To the extent required by Applicable Law, Budget Phone shall provide Verizon with information regarding the type of xDSL technology that it deploys on each shared Loop. Where any proposed change in technology is planned on a shared Loop, Budget Phone must provide this information to Verizon in order for Verizon to update Loop records and anticipate effects that the change may have on the voice grade service and other Loops in the same or adjacent binder groups. 4.6 As described more fully in Verizon Technical Reference 72575, the xDSL technology used by Budget Phone for Line Share Arrangements shall operate within the Power Spectral Density (PSD) limits set forth in T1.413-1998 (ADSL), T1.419-2000 (Splitterless ADSL), or TR59-1999 (RADSL), and MVL (a proprietary technology) shall operate within the 0 to 4 kHz PSD limits of T1.413- 1998 and within the transmit PSD limits of T1.601-1998 for frequencies above 4 kHz, provided that the MVL PSD associated with audible frequencies above 4 kHz shall be sufficiently attenuated to preclude significantly degrading voice services. Budget Phone’s deployment of additional Advanced Services shall be subject to the applicable FCC Rules. 4.7 Budget Phone may only access the high frequency portion of a Loop in a Line Sharing arrangement through an established Collocation arrangement at the Verizon Serving Wire Center that contains the End Office Switch through which voice grade service is provided to Verizon’s Customer. Budget Phone is responsible for providing, through one of the splitter options described below, a splitter at that Wire Center that complies with ANSI specification T1.413, employs Direct Current (DC) blocking capacitors or equivalent technology to assist in isolating high bandwidth trouble resolution and maintenance to the high frequency portion of the frequency spectrum, and operates so that the analog voice "dial tone" stays active when the splitter card is removed for testing or maintenance. Budget Phone is also responsible for providing its own Digital Subscriber Line Access Multiplexer (DSLAM) equipment in the Collocation arrangement and any necessary Customer Provided Equipment (CPE) for the xDSL service it intends to provide (including CPE splitters, filters and/or other equipment necessary for the end user to receive separate voice and data services across the shared Loop). Two splitter configurations are available. In both configurations, the splitter must be provided by Budget Phone and must satisfy the same NEBS requirements that Verizon imposes on its own splitter equipment or the splitter equipment of any Verizon Affiliate. Budget Phone must designate which splitter option it is choosing on the Collocation application or augment. Regardless of the option selected, the splitter arrangements must be installed before Budget Phone submits an order for Line Sharing. Splitter Option A (Splitter Option 1): Splitter in Budget Phone Collocation Area In this configuration, the Budget Phone-provided splitter (ANSI T1.413 or MVL compliant) is provided, installed and maintained by Budget Phone in its own Collocation space within the Customer’s serving End Office. The Verizon- provided dial tone is routed through the splitter in the Budget Phone Collocation area. Any rearrangements will be the responsibility of Budget Phone. Splitter Option C (Splitter Option 2): Splitter in Verizon Area In this configuration, Verizon inventories and maintains a Budget Phone-provided splitter (ANSI T1.413 or MVL compliant) in Verizon space within the Customer’s serving End Office. The splitters will be installed shelf-at-a-time. In those serving End Offices where Verizon employs the use of a POT Bay for interconnection of Budget Phone’s Collocation arrangement with Verizon’s network, the splitter will be installed (mounted) in a relay rack between the POT Bay and the MDF. The demarcation point is at the splitter end of the cable connecting the POT Bay and the splitter. Installation of the splitter will be performed by Verizon or, at Budget Phone’s election, by a Verizon-approved vendor designated by Budget Phone. In those serving End Offices where Verizon does not employ a POT Bay for interconnection of Budget Phone’s Collocation arrangement with Verizon’s network, the Budget Phone provided splitter will be installed (mounted) in a relay rack between the Budget Phone Collocation arrangement and the MDF. The demarcation point is at the splitter end of the cable connecting the Budget Phone Collocation arrangement and the splitter. Installation of the splitter will be performed by Verizon, or, at Budget Phone’s election, by a Verizon-approved vendor designated by Budget Phone. In either scenario, Verizon will control the splitter and will direct any required activity. Where a POT Bay is employed, Verizon will also perform all POT Bay work required in this configuration. Verizon will provide a splitter inventory to Budget Phone upon completion of the required work. 4.7.1 Where a new splitter is to be installed as part of an initial Collocation implementation, the splitter installation may be ordered as part of the initial Collocation application. Associated Collocation charges (application and engineering fees) apply. Budget Phone must submit a new Collocation application, with the application fee, to Verizon detailing its request. Except as otherwise required by Applicable Law, standard Collocation intervals will apply. 4.7.2 Where a new splitter is to be installed as part of an existing Collocation arrangement, or where the existing Collocation arrangement is to be augmented (e.g., with additional terminations at the POT Bay or Budget Phone’s collocation arrangement to support Line Sharing), the splitter installation or augment may be ordered via an application for Collocation augment. Associated Collocation charges (application and engineering fees) apply. Budget Phone must submit the application for Collocation augment, with the application fee, to Verizon. Unless a longer interval is stated in Verizon’s applicable Tariff, an interval of seventy-six (76) Business Days shall apply. 4.8 Budget Phone will have the following options for testing shared Loops: 4.8.1 In serving End Offices where Verizon employs a POT Bay for interconnection of Budget Phone Collocation arrangement with Verizon’s network, the following options shall be available to Budget Phone.

Verizon Avenue is responsible for providing, through one of the splitter options described below, a splitter at that Wire Center that complies with ANSI specification T1.413, employs Direct Current (DC) blocking capacitors or equivalent technology to assist in isolating high bandwidth trouble resolution and maintenance to the high frequency portion of the frequency spectrum, and operates so that the analog voice "dial tone" stays active when the splitter card is removed for testing or maintenance. Verizon Avenue is also responsible for providing its own Digital Subscriber Line Access Multiplexer (DSLAM) equipment in the Collocation arrangement and any necessary Customer Provided Equipment (CPE) for the xDSL service it intends to provide (including CPE splitters, filters and/or other equipment necessary for the end user to receive separate voice and data services across the shared Loop). Two splitter configurations are available. In both configurations, the splitter must be provided by Verizon Avenue and must satisfy the same NEBS requirements that Verizon imposes on its own splitter equipment or the splitter equipment of any Verizon Affiliate. Verizon Avenue must designate which splitter option it is choosing on the Collocation application or augment. Regardless of the option selected, the splitter arrangements must be installed before Verizon Avenue submits an order for Line Sharing. Splitter Option A (Splitter Option 1): Splitter in Verizon Avenue Collocation Area In this configuration, the Verizon Avenue-provided splitter (ANSI T1.413 or MVL compliant) is provided, installed and maintained by Verizon Avenue in its own Collocation space within the Customer’s serving End Office. The Verizon- provided dial tone is routed through the splitter in the Verizon Avenue Collocation area. Any rearrangements will be the responsibility of Verizon Avenue. Splitter Option C (Splitter Option 2): Splitter in Verizon Area In this configuration, Verizon inventories and maintains a Verizon Avenue- provided splitter (ANSI T1.413 or MVL compliant) in Verizon space within the Customer’s serving End Office. The splitters will be installed shelf-at-a-time. In those serving End Offices where Verizon employs the use of a POT Bay for interconnection of Verizon Avenue’s Collocation arrangement with Verizon’s network, the splitter will be installed (mounted) in a relay rack between the POT Bay and the MDF. The demarcation point is at the splitter end of the cable connecting the POT Bay and the splitter. Installation of the splitter will be performed by Verizon or, at Verizon Avenue’s election, by a Verizon-approved vendor designated by Verizon Avenue. In those serving End Offices where Verizon does not employ a POT Bay for interconnection of Verizon Avenue’s Collocation arrangement with Verizon’s network, the Verizon Avenue provided splitter will be installed (mounted) in a relay rack between the Verizon Avenue Collocation arrangement and the MDF. The demarcation point is at the splitter end of the cable connecting the Verizon Avenue Collocation arrangement and the splitter. Installation of the splitter will be performed by Verizon, or, at Verizon Avenue’s election, by a Verizon- approved vendor designated by Verizon Avenue. In either scenario, Verizon will control the splitter and will direct any required activity. Where a POT Bay is employed, Verizon will also perform all POT Bay work required in this configuration. Verizon will provide a splitter inventory to Verizon Avenue upon completion of the required work. 4.7.1 Where a new splitter is to be installed as part of an initial Collocation implementation, the splitter installation may be ordered as part of the initial Collocation application. Associated Collocation charges (application and engineering fees) apply. Verizon Avenue must submit a new Collocation application, with the application fee, to Verizon detailing its request. Except as otherwise required by Applicable Law, standard Collocation intervals will apply. 4.7.2 Where a new splitter is to be installed as part of an existing Collocation arrangement, or where the existing Collocation arrangement is to be augmented (e.g., with additional terminations at the POT Bay or Verizon Avenue’s collocation arrangement to support Line Sharing), the splitter installation or augment may be ordered via an application for Collocation augment. Associated Collocation charges (application and engineering fees) apply. Verizon Avenue must submit the application for Collocation augment, with the application fee, to Verizon. Unless a longer interval is stated in Verizon’s applicable Tariff, an interval of seventy-six (76) Business Days shall apply. 4.8 Verizon Avenue will have the following options for testing shared Loops: 4.8.1 In serving End Offices where Verizon employs a POT Bay for interconnection of Verizon Avenue Collocation arrangement with Verizon’s network, the following options shall be available to Verizon Avenue.

In order for a Loop to be eligible for Line Sharing, the following conditions must be satisfied for the duration of the Line Sharing arrangement: (i) the Loop must consist of a copper loop compatible with an xDSL service that is presumed to be acceptable for shared-line deployment in accordance with FCC rules; (ii) Verizon must be providing simultaneous circuit-switched analog voice grade service to the Customer served by the Loop in question; (iii) the Verizon Customer’s dial tone must originate from a Verizon End Office Switch in the Wire Center where the Line Sharing arrangement is being requested; and (iv) the xDSL technology to be deployed by ICG CLEC on that Loop must not significantly degrade the performance of other services provided on that Loop. 4.3 Verizon shall make Line Sharing available to ICG Rhythms at the rates set forth in Appendix A. These rates and/or rate structures shall be considered interim in nature until they have been approved by the Pricing AttachmentCommission or otherwise allowed to go into effect as a result of a proceeding before the Commission, whether initiated by Rhythms or Verizon, in which Rhythms is offered an opportunity to serve discovery and cross examine witnesses on the methodology and assumptions supporting Verizon’s proposed rates and rate structures, including a tariff investigation, cost proceeding, arbitration or other evidentiary proceeding. If, as a result of any such proceeding, the Commission should approve (or otherwise allow to go into effect) permanent rates and/or rate structures different than those shown in Appendix A, all such approved or effective permanent rates and/or rate structures shall supercede those shown in Appendix A. The permanent rates shall be effective retroactively to the effective date of the agreement.. The Parties shall true-up any amounts previously invoiced as if the permanent rates had been in effect as of that date. Each Party shall invoice the other for any amounts due to it as a result of such true-up, and all such invoices shall be paid in accordance with the Billing and Payment provisions of this Agreement 4.4 In addition to the recurring and nonrecurring charges shown in the Pricing Attachment Appendix A for Line Sharing itself, the following rates shown in the Pricing Attachment Appendix A and in Verizon Verizon’s applicable Tariffs are among those that may apply to a Line Sharing arrangement: (i) prequalification charges to determine whether a Loop is xDSL compatible (i.e., compatible with an xDSL service that is presumed to be acceptable for shared-line deployment in accordance with FCC rules); (ii) engineering query charges, engineering work order charges, or Loop conditioning (Digital Designed Loop) charges; (iii) charges associated with Collocation activities requested by ICGRhythms and not covered by Appendix A; and (iv) misdirected dispatch charges, charges for installation or repair, manual intervention surcharges, and trouble isolation charges, and pair swap/line and station transfer charges. 4.4 4.5 The following ordering procedures shall apply to Line Sharing: 4.4.1 4.5.1 To determine whether a Loop qualifies for Line Sharing, the Loop must first be prequalified to determine if it is xDSL compatible. ICG Rhythms must utilize the mechanized or and manual Loop qualification processes described in the terms applicable to xDSL and Digital Designed Loops Loops, as referenced in Section 4.5.5. below, to make this determination. 4.4.2 ICG 4.5.2 Rhythms shall place orders for Line Sharing by delivering to Verizon a valid electronic transmittal service order or other mutually agreed upon type of service order. Such service order shall be provided in accordance with industry format and specifications or such format and specifications as may be agreed to by the Parties. 4.4.3 4.5.3 If the Loop is prequalified by ICG Rhythms through the Loop prequalification database, and if a positive response is received and followed by receipt of ICG’s Rhythms’ valid, accurate and pre-qualified service order for Line Sharing, Verizon will return an a LSR confirmation within twenty-fourfour (24) hours (weekends and holidays excluded). 4.5.4 If the Loop requires qualification manually or through an Engineering Query, three (3) additional Business Days will be generally be required to obtain Loop qualification results before a LSR confirmation can be returned following receipt of Rhythms’ valid, accurate request. Verizon may in good faith require additional time to complete the Engineering Query where there are poor record conditions, spikes in demand, or other unforeseen events. Nonetheless, Verizon’s performance will be subject to the carrier-to-carrier performance standards established for Engineering Queries. 4.5.5 If conditioning is required to make a Loop capable of supporting Line Sharing and Rhythms orders such conditioning, then Verizon shall provide such conditioning in accordance with the terms of this Agreement pertaining to Digital Designed Loops; or if this Agreement does not contain provisions pertaining to Digital Designed Loops, then in accordance with Verizon’s generally available rates, terms and conditions applicable to Digital Design Loops; provided, however, that Verizon shall not be obligated to provide Loop conditioning if Verizon establishes that such conditioning is likely to degrade significantly the voice-grade service being provided to Verizon’s Customers over such Loops. 4.5.6 The standard provisioning interval for Line Sharing shall be three (3) Business Days. This interval is initiated once the required pre- qualification has been completed. The standard Loop provisioning and installation process will be initiated for Line Sharing only once the requested engineering and conditioning tasks have been completed on the Loop. For example, Pair Swaps or Line Station Transfers will require no less than an additional three (3) Business Days to complete. Scheduling changes and charges associated with order cancellations after conditioning work has been initiated are addressed in the terms pertaining to Digital Designed Loops, as referenced in Section 4.5.5. above. In no event shall the Line Sharing interval applied to Rhythms be longer than the interval applied to any Affiliate of Verizon. 4.5.7 A Pair Swap or Line and Station Transfer done in conjunction with a Line Share Arrangement request involves the reassignment and relocation of an existing Verizon end user voice service from a Digital Loop Carrier ("DLC") facility that is not qualified for line sharing to a spare or freed-up qualified non-loaded copper facility. (A freed-up pair is a qualified, copper pair already assigned.) Such a swap or transfer would be done in order to support the requested service transmission parameters. This new process will be applied to all cases where Verizon encounters the customer on DLC and where Verizon can automatically reassign the customer to a spare copper facility. This effort involves additional installation work including a dispatch and will require an additional charge. Rhythms acknowledges, however that the rate for such charge is not set forth in Appendix A as of the Effective Date, but that Verizon is developing such rate. Verizon shall notify Rhythms in writing of such Rate in accordance with, and subject to, the notices provision of the Interconnection Agreement. 4.5.8 Rhythms must provide all required Collocation, CFA, SBN and NC/NCI information when a Line Sharing Arrangement is ordered. Collocation augments required, either at the POT Bay, Collocation node, or for splitter placement must be ordered using standard collocation applications and procedures, unless otherwise agreed to by the parties or specified in this agreement, such as in section 4.7 4.5.9 The Parties will make reasonable efforts to coordinate their respective roles in order to minimize provisioning problems and facility issues. Rhythms will provide reasonable, timely, and accurate forecasts of its Line Sharing requirements, including splitter placement elections and ordering preferences. These forecasts are in addition to projections provided for other stand-alone unbundled Loop types. 4.6 To the extent required by Applicable Law, Rhythms shall provide Verizon with information regarding the type of xDSL technology that it deploys on each shared Loop. Where any proposed change in technology is planned on a shared Loop, Rhythms must provide this information to Verizon in order for Verizon to update Loop records and anticipate effects that the change may have on the voice grade service and other Loops in the same or adjacent binder groups. As described more fully in Verizon Technical Reference 72575, the xDSL technology used by Rhythms for Line Share Arrangements shall operate within the Power Spectral Density (PSD) limits set forth in T1.413-1998 (ADSL), T1.419-2000 (Splitterless ADSL), or TR59-1999 (RADSL), and MVL (a proprietary technology) shall operate within the 0 to 4 kHz PSD limits of T1.413-1998 and within the transmit PSD limits of T1.601-1998 for frequencies above 4 kHz, provided that the MVL PSD associated with audible frequencies above 4 kHz shall be sufficiently attenuated to preclude significantly degrading voice services. Rhythms’ deployment of additional Advanced Services shall be subject to the applicable rules and regulations of the FCC. 4.7 Rhythms may only access the high frequency portion of a Loop in a Line Sharing arrangement through an established Collocation arrangement at the Verizon Serving Wire Center that contains the End Office Switch through which voice grade service is provided to Verizon’s Customer. Rhythms is responsible for providing a splitter at that Wire Center that complies with ANSI specification T1.413 through one of the splitter options described below. (The Siecor splitter proposed for use by Rhythms as of May 12, 2000 is deemed by both Parties to be compliant with ANSI T1.413.) Rhythms is also responsible for providing its own DSLAM equipment in the Collocation arrangement and any necessary CPE for the xDSL service it intends to provide (including CPE splitters, filters and/or

Such service order shall be provided in accordance with industry format and specifications or such format and specifications as may be agreed to by the Parties. 4.4.3 (iii) If the Loop is prequalified by ICG SPRINT through the Loop prequalification database, and if a positive response is received and followed by receipt of ICGSPRINT’s valid, accurate and pre-qualified service order for Line Sharing, Verizon VERIZON will return an LSR a Local Service Request (LSR) confirmation within twenty-fourfour (24) hours (weekends and holidays excluded) for LSRs with less than six (6) loops and within 72 hours (weekends and holidays excluded) for LSRs with six (6) or more loops. (iv) If the Loop requires qualification manually or through an Engineering Query, three (3) additional business days will generally be required to obtain Loop qualification results before an order confirmation can be returned following receipt of SPRINT’s valid, accurate request. VERIZON may require additional time to complete the Engineering Query where there are poor record conditions, spikes in demand, or other unforeseen events. (v) If conditioning is required to make a Loop capable of supporting Line Sharing and SPRINT orders such conditioning, then VERIZON shall provide such conditioning in accordance with the terms of this Agreement pertaining to Digital Designed Loops; provided, however, that VERIZON shall not be obligated to provide Loop conditioning if VERIZON establishes, in the manner required by Applicable Law, that such conditioning is likely to degrade significantly the voice-grade service being provided to VERIZON’s Customers over such Loops. (vi) The standard Loop provisioning and installation process will be initiated for the Line Sharing arrangement only once the requested engineering and conditioning tasks have been completed on the Loop. Scheduling changes and charges associated with order cancellations after conditioning work has been initiated are addressed in the terms pertaining to Digital Designed Loops, as referenced in paragraph (v) above. The standard provisioning interval for the Line Sharing arrangement shall be as set out in the VERIZON Product Interval Guide; provided that the standard provisioning interval for the Line Sharing arrangement shall not exceed the shortest of the following intervals: (a) six (6) business days; (b) the standard provisioning interval for the Line Sharing arrangement that is stated in an applicable VERIZON Tariff (including, but not limited to, to the extent applicable, VERIZON Tariff Pa. P.U.C.-No. 216); or, (c) the standard provisioning interval for the Line Sharing arrangement that is required by Applicable Law. The standard provisioning interval for the Line Sharing arrangement shall commence only once any requested engineering and conditioning tasks have been completed. A Line Sharing arrangement that requires pair swaps or line and station transfers in order to free-up facilities may have a provisioning interval that is longer than the standard provisioning interval for the Line Sharing arrangement. In no event shall the Line Sharing interval applied to SPRINT be longer than the interval applied to any similarly situated affiliate of VERIZON. (vii) SPRINT must provide all required Collocation, CFA, Special Xxxx Number (SBN) and NC/NCI information when a Line Sharing Arrangement is ordered. Collocation augments required, either at the Point of Termination (POT) Bay, Collocation node, or for splitter placement, must be ordered using standard collocation applications and procedures, unless otherwise agreed to by the Parties or specified in this Agreement. (viii) The Parties recognize that Line Sharing is an offering that requires both Parties to make reasonable efforts to coordinate their respective roles in order to minimize Line Sharing provisioning problems. SPRINT will provide to VERIZON forecasts of SPRINT's Line Sharing requirements. The forecasts will be provided within 45 days after the Effective Date of this Agreement and thereafter in February and August of each year, will cover a period of one year commencing with the month after the month in which the forecast is submitted, and will state, for each month in the forecast period, the locations where Line Sharing arrangements will be purchased, the volume of Line Sharing arrangements that will be purchased at each such location, splitter placement elections, and ordering preferences. These forecasts are in addition to projections provided for other stand-alone unbundled Loop types. 1.2.10.4 To the extent required by Applicable Law (including, but not limited to, 47 CFR § 51.231), SPRINT shall provide VERIZON with information regarding the type of xDSL technology that it deploys on each shared Loop. The xDSL technology used by SPRINT for Line Share Arrangements shall operate within the Power Spectral Density (PSD) limits set forth in T1.413-1998 (ADSL), T1.419-2000 (Splitterless ADSL), or TR59-1999 (RADSL), and MVL (a proprietary technology) shall operate within the 0 to 4 kHz PSD limits of T1.413-1998 and within the transmit PSD limits of T1.601-1998 for frequencies above 4 kHz, provided that the MVL PSD associated with audible frequencies above 4 kHz shall be sufficiently attenuated to preclude significantly degrading voice services. SPRINT’s deployment of additional Advanced Services shall be subject to the applicable rules and regulations of the FCC. 1.2.10.5 SPRINT may only access the high frequency portion of a Loop in a Line Sharing arrangement through an established Collocation arrangement at the VERIZON Serving Wire Center that contains the End Office Switch through which voice grade service is provided to VERIZON’s Customer. SPRINT is responsible for providing, through one of the splitter options described below, a splitter at that Wire Center that complies with ANSI specification T1.413, employs Direct Current (DC) blocking capacitors or equivalent technology to assist in isolating high bandwidth trouble resolution and maintenance to the high frequency portion of the frequency spectrum, and operates so that the analog voice "dial tone" stays active when the splitter card is removed for testing or maintenance. SPRINT is also responsible for providing its own Digital Subscriber Line Access Multiplexer (DSLAM) equipment in the Collocation arrangement and any necessary Customer Provided Equipment (CPE) for the xDSL service it intends to provide (including CPE splitters, filters and/or other equipment necessary for the end user to receive separate voice and data services across the shared Loop). Two splitter configurations are available. In both configurations, the splitter must be provided by SPRINT and must satisfy the same NEBS requirements that VERIZON imposes on its own splitter equipment or the splitter equipment of any VERIZON Affiliate. SPRINT must designate which splitter option it is choosing on the Collocation application or augment. Regardless of the option selected, the splitter arrangements must be installed before SPRINT submits an order for Line Sharing.
