This point is where network access recurring charges and BA responsibility stop and beyond which Customer responsibility begins.

          1.62 “Rating Point” or “Routing Point” means a specific geographic point identified by a specific V&H coordinate. The Rating Point is used to route inbound traffic to specified NPA-NXXs and to calculate mileage measurements for distance-sensitive transport charges of switched access services. Pursuant to Bellcore Practice BR-795-100-100, the Rating Point may be an End Office location or a “LEC Consortium Point of Interconnection.” Pursuant to that same Bellcore Practice, examples of the latter shall be designated by a common language location identifier (“CLLI”) code with (x)KD in positions 9, 10, 11, where (x) may be any alphanumeric A-Z or 0-9. The Rating Point/Routing Point must be located within the LATA in which the corresponding NPA-NXX is located. However, the Rating Point/Routing Point associated with each NPA-NXX need not be the same as the corresponding Rate Center Point, nor must it be located within the corresponding Rate Center Area, nor must there be a unique and separate Rating Point corresponding to each unique and separate Rate Center Area.

          1.63 “Service Control Point” or “SCP” means the node in the Common Channel Signaling network to which informational requests for service handling, such as routing, are directed and processed. The SCP is a real time database system that, based on a query from a service switching point (“SSP”) and via a Signaling Transfer Point, performs subscriber or application-specific service logic, and then sends instructions back to the SSP on how to continue call processing.

Subtending Central Offices shall be determined in accordance with and as identified in the Local Exchange Routing Guide (“LERG”). Switched Exchange Access Service traffic is not Tandem Transit Traffic.

          1.71 “Tariff’ means any applicable federal or state Tariff of a Party, or standard agreement or other document that sets forth the generally available terms and conditions, each as may be amended by the Party from time to time, under which a Party offers a particular service, facility or arrangement.

          1.72 “Toll Traffic” means traffic that is originated by a Customer of one Party on that Party’s network and terminates to a Customer of the other Party on that Party’s network and is not Local Traffic or Ancillary Traffic. Toll Traffic may be either “IntraLATA Toll Traffic” or “InterLATA Toll Traffic,” depending on whether the originating and terminating points are within the same LATA.

          1.73 “Trunk Side” means a Central Office Switch connection that is capable of, and has been programmed to treat the circuit as, connecting to another switching entity (.g., another carrier’s network). Trunk Side connections offer those transmission and signaling features appropriate for the connection of switching entities.

          1.75 “Wire Center” means a building or portion thereof which serves as a Routing Point for Switched Exchange Access Service. The Wire Center serves as the premises for one or more Central Offices.

2.0 INTERPRETATION AND CONSTRUCTION

          2.1 All references to Sections, Exhibits and Schedules shall be deemed to be references to Sections of, and Exhibits and Schedules to, this Agreement unless the context shall otherwise require. The headings used in this Agreement are inserted for convenience of reference only and are not intended to be a part of or to affect the meaning of this Agreement. Unless the context shall otherwise require, any reference to any agreement, other instrument (including BA or other third party offerings, guides or practices), statute, regulation, governmental rule or Tariff is to such agreement, instrument, statute, regulation, or governmental rule or Tariff as amended and supplemented from time to time (and, in the case of a statute, regulation, governmental rule or Tariff, to any successor provision).

          2.2 Each Party hereby incorporates by reference those provisions of its Tariffs that govern the provision of any of the services or facilities provided hereunder. Subject to the terms set forth in Section 20 regarding rates and charges, if any provision of this Agreement and an applicable Tariff cannot be reasonably construed or interpreted to avoid conflict, the provision contained in this Agreement shall prevail. If any provision contained in this main body of the - Agreement and any Schedule or Exhibit hereto cannot be reasonably construed or interpreted to avoid conflict, the provision contained in this main body of the Agreement shall prevail. The fact that a condition, right, obligation, or other term appears in this Agreement but not in any such Tariff or in such Tariff but not in this Agreement, shall not be interpreted as, or be deemed grounds for finding, a conflict for purposes of this Section 2.

          2.3 This Agreement is intended as a successor to the Interconnection Agreement between the same Parties for New Hampshire. Any provision of this Agreement that requires or permits a Party to take certain actions (such as submitting service orders, installing facilities, or providing information) shall not be interpreted as requiring either Party to repeat actions that were already taken under the previous agreement, unless the requirements of this Agreement are inconsistent with the arrangements previously in place between the Parties; provided, however, that for the avoidance of any doubt, the foregoing shall not apply to (a) any new services, facilities, or Network Elements for which Level 3 submits an order, request, or application after the Effective Date, (b) nor to any pending (but not yet provisioned) services, facilities, or Network Elements for which Level 3 submits an order, request, or application after the Effective Date of this Agreement to modify or add to the pending (i.e., submitted by Level 3 prior to the Effective Date of this Agreement, but not yet fulfilled) order, request, or application, (c) nor to any existing services, facilities, or Network Elements for which Level 3 submits an order, request, or application after the Effective Date of this Agreement to modify the same. Rather, in

10

the case of subsections (a), (b), and (c) directly above, any orders, requests, applications submitted by Level 3 after the Effective Date of this Agreement shall be governed by the rates, terms, and conditions of this Agreement. Whenever possible, services provided under the previous agreement shall be continued without interruption under the rates, terms, and conditions of this Agreement. Nothing in this Agreement is intended to extinguish any obligation of either Party to pay for services provided under the previous agreement but not yet billed or paid for, or any other obligation arising under the previous agreement that, by the teiuis of that agreement or by the nature of the obligation, survives the termination of that agreement.

          13.6 Joint Planning and Implementation Intervals

                    13.6.1 Upon BA’s receipt of a written request from Level 3, BA shall provide to Level 3 point of termination bay assignments for a Collocation arrangement; BA shall provide such assignments to Level 3 at least ten (10) days prior to the date of completion of the

19

Collocation arrangement, so long as BA has had a reasonable amount of time to respond to Level 3’s request for such information. Upon Level 3’s reasonable request for additional information relating to its Collocation arrangement, BA shall work cooperatively and in good faith with Level 3 to supply such information as it becomes available.

                    13.6.2 For each Collocation request submitted by Level 3, the Parties shall meet to develop a set of major milestones for such request. BA and Level 3 shall work cooperatively to meet such milestones. The Parties shall conduct additional joint planning meetings if, and, as reasonably required.

                    13.6.3 After completion of construction, Level 3 and BA will complete an acceptance walkthrough of all collocated space requested from BA. Exceptions that are noted during this acceptance walkthrough and mutually agreed to by the Parties shall be corrected by BAwithin thirty (30) calendar days after the walkthrough.

                    13.6.5 Subject to the applicable BA Tariff bona fide request process, and only to the extent required by Applicable Law, Level 3 is entitled to a rebuttable presumption that its requested Collocation arrangement is technically feasible if any local exchange carrier has deployed such an arrangement in any incumbent local exchange carrier premises.

                    13.6.6 Equipment deployed by Level 3 at the BA premises will meet the safety requirements defined in BA’s NEBS Requirements Document RNSA-NEB-95-0003. BA shall not impose any equipment safety requirements upon Level 3 that are more stringent than the requirements it places upon its own equipment, nor shall BA require that collocated equipment meets NEBS performance requirements. If BA denies Collocation on safety grounds, it shall provide Level 3 a list that includes all equipment in the BA premises, together with an affidavit attesting that this equipment meets or exceeds the relevant safety standard, within five (5) business days of the denial; provided, however, that the scope of the equipment BA is required to provide on such a list will be determined in accordance with Applicable Law. BA may obtain an extension of this interval upon receipt of written consent from Level 3, which consent shall not unreasonably be withheld.

                    13.6.7 Upon written request by Level 3 to utilize a vendor not previously approved or authorized by BA, BA shall not unreasonably delay consideration of whether BA shall approve or authorize Level 3 or any entity designated by Level 3 as a vendor eligible to work in BA premises. Such requests for approval or authorization shall be considered in a

20

nondiscriminatory manner pursuant to published certification or approval standards provided by BA to Level 3.

14.0 NUMBER PORTABILITY — SECTION 251(b)(2)

          14.1 Scope

The Parties shall provide Number Portability (“NP”) in accordance with the Act, rules and regulations as from time to time prescribed by the FCC and the Commission, as applicable, and applicable industry standards.

          14.2 Procedures for Providing LNP (“Long-term Number Portability”)

          The Parties will follow the LNP provisioning process recommended by the North American Numbering Council (NANC) and adopted by the FCC. In addition, the Parties agree to follow the LNP ordering procedures established at the Ordering and Billing Forum (“OBF”). The Parties shall provide LNP on a reciprocal basis.

                    14.2.1 LNP applies when a Customer of one Party (“Party A”) elects to become a Customer of the other Party (“Party B”) and also elects to utilize the original telephone number(s) corresponding to the Telephone Exchange Service(s) it previously received from Party A, in conjunction with the Telephone Exchange Service(s) it will now receive from Party B. After Party B has received appropriate authorization in accordance with Applicable Law from an end user Customer and sends an LSR to Party A, Parties A and B will work together to port the Customer’s telephone number(s) from Party A’s network to Party B’s network. It is Party B’s responsibility to maintain a file of all such authorizations. Upon written request from Party A, Party B shall provide a copy of any such authorization.

                    14.2.2 When a telephone number is ported out of Party A’s network, Party A will remove any non-proprietary line based calling card(s) associated with the ported number(s) from its Line Information Database (“LIDB”). Reactivation of the line-based calling card in another LIDB, if desired, is the responsibility of Party B or Party B’s Customer.

                    14.2.3 When a Customer of Party A ports his or her telephone numbers to Party B and the Customer has previously secured a reservation of line numbers from Party A for possible activation at a future point, these reserved but inactive numbers may be ported along with the active numbers to be ported provided the numbers have been reserved for the Customer. Party B may request that Party A port all reserved numbers assigned to the Customer or that Party A port only those numbers listed by Party B. As long as Party B maintains reserved but inactive numbers ported for the Customer, Party A shall not reassign those numbers. Party B shall not reassign the reserved numbers to another end user Customer.

                    14.2.4 When a Customer of Party A ports his or her telephone numbers to Party B, in the process of porting the Customer’s telephone numbers, Party A shall implement the ten-digit trigger feature where it is available. When Party A receives the porting request, the unconditional

21

trigger shall be applied to the Customer’s line before the due date of the porting activity. When the ten-digit unconditional trigger is not available, Party A and Party B must coordinate the disconnect activity.

                    14.2.5 The Parties shall furnish each other with the Jurisdiction Information Parameter (HP) in the Initial Address Message (TAM), containing a Local Exchange Routing Guide (LERG)-assigned NPA-NXX (6 digits) identifying the originating switch on calls originating from LNP capable switches.

                    14.2.6 Where LNP is commercially available, the NXXs in the End Office shall be defined as portable, except as noted in Section 14.2.7, and translations will be changed in the Parties’ switches to open those NXXs for database queries in all applicable LNP capable End Officeswithin the LATA of the given switch(es). On a prospective basis,all newly deployed switches will be equipped with LNP capability and so noted in the LERG, pursuant to schedules and requirements, if any, set forth under industry standards and/or Applicable Law.

                    14.2.7 All NXXs assigned to LNP capable switches are to be designated as portable unless an NXX(s) has otherwise been designated as non-portable. Non-portable NXXs include NXX codes assigned. to paging, cellular and wireless services; codes assigned for internal testing and official use and any other NXX codes required to be designated as non-portable by the rules and regulations of the FCC. NXX codes assigned to mass calling on a choked network may not be ported using LNP technology but are portable using methods established by the NANC and adopted by the FCC. On a prospective basis, newly assigned codes in switches capable of porting shall become commercially available for porting with the effective date in the network, pursuant to schedules and requirements, if any, set forth under industry standards and/or Applicable Law.

                    14.2.8 Both Parties’ use of LNP shall meet the performance criteria specified by the FCC. Both Parties will act as the default carrier to perform the query for location routing number for the other Party in the event that either Party is unable to perform the routing necessary for LNP.

          14.3 Procedures for Providing NP Through Full NXX Code Migration

          Where a Party has activated an entire NXX for a single Customer, or activated at least eighty percent (80%) of an NXX for a single Customer, with the remaining numbers in that NXX either reserved for future use by that Customer or otherwise unused, if such Customer chooses to receive Telephone Exchange Service from the other Party, the first Party shall cooperate with the second Party to have the entire N)0( reassigned in the LERG (and associated industry databases, routing tables, etc.) to an End Office operated by the second Party. Such transfer will be accomplished with appropriate coordination between the Parties and subject to appropriate industry lead-times for movements of NXXs from one switch to another. Neither Party shall charge the other in connection with this coordinated transfer.

15.0 DIALING PARITY — SECTION 251(b)(3)

BA and Level 3 shall each provide the other with nondiscriminatory access to such services and information as are necessary to allow the other Party to implement Dialing Parity for Telephone Exchange Service, operator services, directory assistance, and directory listing information with no unreasonable dialing delays, as required under Section 251(b)(3) of the Act.

16.0 ACCESS TO RIGHTS-OF-WAY — SECTION 251(b)(4)

          16.1 To the extent required by Applicable Law and where facilities are available, each Party (“Licensor”) shall provide the other Party (“Licensee”) access for purposes of making attachments to the poles, ducts, rights-of-way and conduits it owns or controls pursuant to any existing or future license agreement between the Parties. Such access shall be in conformance with 47 U.S.C. § 224 and on terms, conditions and prices comparable to those offered to any other entity pursuant to each Party’s applicable Tariffs (including generally-available license agreements).

          16.2 Licensor shall process all completed license applications for new or additional attachments, including the performance of a pre-license survey, on a first-come, first-serve basis as set forth in its applicable Tariff. Licensor shall make all access determinations in accordance with the requirements of Applicable Law (including any applicable FCC Regulations), considering such factors as capacity, safety, reliability and general engineering considerations. Licensor shall inform Licensee in writing as to whether an application has been granted (subject to Licensee’s payment for any “make-ready” work that may be required) or denied within forty-five (45) days of receipt of such application. Where an application involves an increase in capacity by Licensor, Licensor shall take reasonable steps to accommodate requests for access in accordance with Applicable Law. Before denying Licensee access based on lack of capacity, Licensor shall explore potential accommodations in good faith with Licensee. In order to facilitate Licensee’s completion of an application, Licensor shall make commercially reasonable efforts to, within fifteen (15) business days of a legitimate request identifying the specific geographic area and types and quantities of required structures, provide Licensee such maps, plats or other relevant data reasonably necessary to complete the applications described above, subject to a non-disclosure agreement in form reasonably agreeable to Licensor. Such requests shall be processed by Licensor on a first-come, first-serve basis. This exchange of information and records does not preclude the need for a field survey to verify the location and availability of structures and rights of way to be used. Licensor shall make commercially reasonable efforts to meet with or respond to Licensee’s inquiries regarding the information supplied to it as soon as practicable following receipt of such request for meeting or inquiry from Licensee. Completion of make-ready work and attachments shall be in accordance with any existing or future license agreement between the Parties.

Referral Announcements shall be provided reciprocally, free of charge to either the other Party or the Customer to the extent the providing Party does not charge its own Customers for such service, for a period of not less than four (4) months after the date the Customer changes its telephone number in the case of business Customers and not less than sixty (60) days after the date the Customer changes its telephone number in the case of residential Customers.

          18.2 Coordinated Repair Calls

          Level 3 and BA will employ the following procedures for handling misdirected repair calls:

                    18.2.1 Level 3 and BA will educate their respective Customers as to the correct telephone numbers to call in order to access their respective repair bureaus.

                    18.2.2 To the extent Party A is identifiable as the correct provider of service to Customers that make misdirected repair calls to Party B, Party B will immediately refer the Customers to the telephone number provided by Party A, or to an information source that can provide the telephone number of Party A, in a courteous manner and at no charge. In responding to misdirected repair calls, neither Party shall make disparaging remarks about the other Party, its services, rates, or service quality.

                    18.2.3 Level 3 and BA will provide their respective repair contact numbers to one another on a reciprocal basis.

          18.3 Customer Authorization

                    18.3.1 Without in any way limiting either Party’s obligations under subsection 27.1, each Party shall comply with Applicable Law with regard to Customer selection of a primary Telephone Exchange Service provider.

                    18.3.2 In the event either Party requests that the other Party install, provide, change, or terminate a Customer’s Telecommunications Service (including, but not limited to, a Customer’s selection of a primary Telephone Exchange Service Provider) and (a) fails to provide documentary evidence of the Customer’s primary Telephone Exchange Service Provider

24

selection upon request, or (b) fails to obtain authorization from the Customer for such installation, provision, selection, change or termination in accordance with Applicable Law, then in addition to any other rights or remedies available to the other Party, the requesting Party shall be liable to the other Party for all charges that would be applicable to the Customer for the initial change in the Customer’s Telecommunications Service and any charges for restoring the Customer’s Telecommunications Service to its Customer-authorized condition, including to the appropriate primary Telephone Exchange Service provider.

                    18.3.3 Without in any way limiting Level 3’s obligations under subsection 27.1, Level 3 shall comply with Applicable Law with regard to Customer Proprietary Network Information, including, but not limited to, 47 U.S.C. § 222. Level 3 shall not access (including, but not limited to, through BA OSS Services (as defined in Schedule 12.3) and BA Pre-OSS Services), use, or disclose Customer Proprietary Network Information made available to Level 3 by BA pursuant to this Agreement unless Level 3 has obtained any Customer authorization for such access, use and/or disclosure required by Applicable Law. By accessing, using or disclosing Customer Proprietary Network Information, Level 3 represents and warrants that it has obtained authorization for such action from the applicable Customer in the manner required by Applicable Law and this Agreement. Level 3 shall, upon request by BA, provide proof of such authorization (including a copy of any written authorization).

                    18.3.4 BA shall have the right to monitor and/or audit Level 3’s access to and use and/or disclosure of Customer Proprietary Network Information that is made available by BA to Level 3 pursuant to this Agreement to ascertain whether Level 3 is complying with the requirements of Applicable Law and this Agreement with regard to such access, use, and/or disclosure.

20.0 RATES AND CHARGES; ASSURANCE OF PAYMENT

          20.1 Except as provided elsewhere in this Agreement, the rates and charges set forth in Exhibit A hereto shall apply to the services, facilities, and arrangements provided hereunder and used for the provision of Telephone Exchange Service and associated Exchange Access. To the extent that services, facilities or arrangements are not included in Exhibit A, or the rates and charges therefor are not set forth in Exhibit A or elsewhere in this Agreement, the providing Party may charge its applicable, effective and nondiscriminatory Tariff rate that has been approved or otherwise allowed to go into effect by the Commission or the FCC.

          20.2 Notwithstanding Section 20.1 hereof, the rates and charges set forth in Exhibit A shall be superseded by any new rate or charge when such new rate or charge is required by any order of the Commission or the FCC, approved by the Commission or the FCC, or otherwise allowed to go into effect, provided such new rates or charges are not subject to a stay issued by any court or regulatory body of competent jurisdiction. Notwithstanding any other provision of this

26

Agreement, each Party reserves its respective right to file a complaint with the Commission with respect to the Tariff rates and charges of the other Party.

          20.3 Upon request by BA, Level 3 shall, at any time and from time to time, provide to BA adequate assurance of payment of amounts due (or to become due) to BA hereunder. Assurance of payment of charges may be requested by BA if Level 3 (a) in BA’s reasonable judgment, at the Effective Date or at any time thereafter, is unable to demonstrate that it is creditworthy, (b) fails to timely pay (or fails to give notice of a bona fide dispute pursuant to Section 28.8 hereof with respect to) a bill rendered to Level 3 by BA, (c) in BA’s reasonable judgment, at the Effective Date or at any time thereafter, does not have established credit with BA or (d) admits its inability to pay its debts as such debts become due, has commenced a voluntary case (or has had a case commenced against it) under the U.S. Bankruptcy Code or any other law relating to bankruptcy, insolvency, reorganization, winding-up, composition or adjustment of debts or the like, has made an assignment for the benefit of creditors or is subject to a receivership or similar proceeding.

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 bill 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.

                    28.6.2 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, and such Applicable 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

36

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 Section 28.6.6 of this Agreement of its intent to pay the Receipts Tax and (ii) shall timely pay the Receipts Tax to the applicable tax authority.

                    28.6.3 Taxes Imposed on Customers.

                    28.6.4 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 Section 28.6.1, 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 Section 28.6.1, 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 Section 28.6.1 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 Section 28.6.2, 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 Section 28.6.3, 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.

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

37

inquiries in a proper and timely manner so that the audit and/or any resulting controversy may be resolved expeditiously.

                    28.6.5 Tax Exemptions and Exemption Certificates. If Applicable Law clearly exempts a purchase hereunder from a Tax, and if such Applicable 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 Section 28.6.6. 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 Applicable 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.

                    28.6.6 If any discount or portion of a discount in price provided to Level 3 under this Agreement (including, but not limited to, a wholesale discount provided for in Exhibit A) is based on, anticipated Tax savings to BA because it was anticipated that receipts from sales of BA services that would otherwise be subject to a Tax on such receipts could be excluded from such Tax under Applicable Law because the BA services would be sold to Level 3 for resale, and BA is, in fact, required by Applicable Law to pay such Tax on receipts from sales of BA services to Level 3, then, as between BA and Level 3, Level 3 shall be liable for, and shall indemnify and hold harmless BA against (on an after-tax basis), any such Tax and any interest and/or penalty assessed by the applicable taxing authority on either Level 3 or BA with respect to the Tax on BA’s receipts.

                    28.6.7 All notices, affidavits, exemption-certificates or other communications required or permitted to be given by either Party to the other, for purposes of this Section 28.6, 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 Section 28.10 as well as to the following:

                    28.8.2 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 ??????? 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.

                    28.8.3 If any portion of an amount due to a Party (the “Billing Party”) under this Agreement is subject to abona fide dispute between the Parties, the Party billed (the “Non-Paying Party”) shallwithin 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 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.

                    28.8.5 If the Parties are unable to resolve issues related to the Disputed Amounts within thirty (30) days after the Parties’ appointment of designated representatives pursuant to Section 28.8.4, or if either Party fails to appoint a designated representative within thirty (30) days of the end of the thirty (30) day period referred to Section 28.8.4, then either Party may file a complaint with the Commission or any other authority of competent jurisdiction to resolve such issues or proceed with any other remedy pursuant to law or equity.

                    28.8.6 The Parties agree that all negotiations pursuant to this Section 28.8 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.

                    28.8.7 Charges which are not paid by the due date stated on BA’s billshall be subject to a late payment charge. The late payment charge shall be an amount specified by BA which shall not exceed a rate of one and one half percent (1 1/12%) of the overdue amount (including any unpaid previously billed late payment charges) per month.

          28.11 Joint Work Product

          This Agreement is the joint work product of the Parties and has been negotiated by the Parties and their respective counsel and shall be fairly interpreted in accordance with its terms and, in the event of any ambiguities, no inferences shall be drawn against either Party.

          28.12 No Third Party Beneficiaries

          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.

          28.13 No Licenses

                    28.13.1 Nothing in this Agreement shall be construed as the grant of a license 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.

                    28.13.2 Except as may be required under Section 28.13.4 hereof, 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.

                    28.13.3 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 EACH PARTY OF THE OTHER’S FACILITIES, ARRANGEMENTS, OR SERVICES PROVIDED UNDER THIS AGREEMENT SHALL NOT GIVE RISE TO A CLAIM OF INFRINGEMENT, MISUSE, OR MISAPPROPRIATION OF ANY INTELLECTUAL PROPERTY RIGHT.

                    28.13.4 Level 3 agrees that the rights granted by BA hereunder shall, where applicable, be subject to the restrictions, if any, contained in any current software license agreements between BA and BA’s software vendors. If BA asserts any such restrictions, BA shall

42

provide written notice thereof to Level 3, and upon receipt of written request by Level 3, BA shall provide a copy of the applicable restrictive provisions in the subject license agreement(s), except to the extent that BA is prohibited from doing so by a confidentiality obligation; provided, however, that in the case of such a confidentiality obligation, BA shall exercise commercially reasonable best efforts to make a copy of the subject license agreement(s) available to Level 3, although in no event shall BA be required to expend funds or undertake any additional obligations to make such information available to Level 3. Level 3 acknowledges that functions and features made available to it hereunder through the use of third party proprietary products may involve additional terms and conditions and/or separate licensing to Level 3; provided, however, BA agrees that it shall comply with the requirements, if any, of Applicable Law with respect to making efforts to secure intellectual property rights from third parties necessary for Level 3 to make use of BA services and facilities.

          28.14 Technology Upgrades

          Notwithstanding any other provision of this Agreement, BA shall have the right to deploy, upgrade, migrate and maintain its network at its discretion. The Parties acknowledge that BA, at its election, may deploy fiber throughout its network and that such fiber deployment mayinhibit or facilitate Level 3’s ability to provide service using certain technologies. Nothing in this Agreement shall limit BA’s ability to upgrade its network through the incorporation of new equipment, new software or otherwise. Level 3 shall be solely responsible for the cost and effort of accommodating such changes in its own network. BA shall, however, notify Level 3 in writing of any technology upgrades that would materially affect BA’s provision of services or facilities hereunder, as soon as reasonably possible after the decision is made to implement such upgrades, so that Level 3 will have reasonable time to make alternative arrangements as necessary. In no event shall such notice be less than sixty (60) days in advance of the upgrade to be implemented by BA.

          28.15 Survival

          The Parties’ obligations under this Agreement which by their nature are intended to continue beyond the termination or expiration of this Agreement (including, without limitation, the obligation to pay amounts owed hereunder (to include indemnification obligations) and the obligation to protect the other Party’s Proprietary Information) shall survive the termination or expiration of this Agreement.

          28.16 Entire Agreement

          The terms contained in this Agreement and any Schedules, Exhibits, Tariffs and other documents or instruments referred to herein that are incorporated into this Agreement by this reference constitute the entire agreement between the Parties with respect to the subject matter hereof, and supersede any and all understandings, proposals and other communications, oral or written regarding such subject matter that have been made or entered into prior to the effective date hereof, November 1, 2000. 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

43

form documents, purchase orders, quotations, acknowledgments, invoices or other communications.

          28.17 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.

          28.18 Modification, Amendment, Supplement, or Waiver

          No modification, amendment, supplement to, or waiver of the Agreement or any of its provisions shall be effective and binding upon the Parties unless it is made in writing and duly signed by the Parties. A failure or delay of either Party to enforce any of the provisions hereof, to exercise any option which is herein provided, or to require performance of any of the provisions hereof shall in no way be construed to be a waiver of such provisions or options.

          28.19 Successors and Assigns

          This Agreement shall be binding on and inure to the benefit of the Parties and their respective legal successors and permitted assigns.

          28.20 Publicity and Use of Trademarks or Service Marks

          Neither Party nor its subcontractors or agents shall use the other Party’s trademarks, service marks, logos or other proprietary trade dress in any advertising, press releases, publicity matters or other promotional materials without such Party’s prior written consent.

          28.21 Cooperation With Law Enforcement

          BA may cooperate with law enforcement authorities to the full extent required or permitted by Applicable Law in matters related to services provided by BA hereunder, including, but not limited to, the production of records; the establishment of new lines or the installation of new services on an existing line in order to support law enforcement operations; and the installation of wiretaps, trap-or-trace devices and pen registers. BA shall not have the obligation to inform the Customers of Level 3 of such law enforcement requirements, except to the extent required by Applicable Law. BA will inform Level 3 of such law enforcement requirements, unless an appropriate governmental authority requests that notice to Level 3 be withheld, or such disclosure is otherwise inconsistent with Applicable Law. Where a law enforcement requirement relates to the establishment of new lines (including, but not limited to, lines established to support interception of communications on other lines), or the installation of services on existing lines, BA may take measures to prevent CLECs from obtaining access to information concerning such lines or services through operations support system interfaces, whenever an appropriate governmental authority so requests. A requirement that the existence of the lines or services not be disclosed shall be interpreted as including a requirement to block access to information concerning the lines or services through operations support system interfaces. BA will not be

44

liable to any person for any economic harm, personal injury, invasion of any right of privacy, or any other harm, loss or injury, caused or claimed to be caused, directly or indirectly, by actions taken by BA to block, or by its failure to block, access to information concerning particular lines or services through operations support systems interfaces or otherwise.

          28.22 CLEC Certification

          Notwithstanding any other provision of this Agreement, BA shall have no obligation to perform under this Agreement until such time as Level 3 has obtained a Certificate of Public Convenience and Necessity (CPCN) or such other Commission authorization as may be required by law as a condition for conducting business in New Hampshire as a local exchange carrier.

          28.23 Section 252(i)

          Except as set forth in Section 5.7.3 hereof, nothing in this Agreement shall be construed to prevent either Party from exercising any rights it may hold under Section 252(i) of the Act. Except as set forth in Section 5.7.3 hereof, nothing in this Agreement shall be construed to excuse either Party from any obligations it may bear under Section 252(i) of the Act.

45

          IN WITNESS WHEREOF, the Parties hereto have caused this Agreement to be executed as of this 1^st day of November, 2000.
