H. Except for new service features, service options or service promotions, which will become effective immediately upon their posting in the Guide on the Companys website, any modification made to the Guide will become effective beginning on the first day of the next calendar month following its posting on the Companys website or thereafter, on the first day of the next Service billing cycle whenever adjustments are made to rates and charges, provided that no modification shall become effective and binding on Customer until it has been posted in the Guide for at least fifteen (15) calendar days. The Company reserves the right to modify the rates and charges for the Service and to modify or eliminate Service offerings or features. Such modifications will become effective and binding upon Customer after such modifications have been posted in the Guide for at least fifteen (15) calendar days. If the Company notifies Customer of the elimination of a Service offering or feature or of an increase in Service charges or rates, Customer may terminate this Service Attachment without incurring a cancellation or early termination charge by providing the Company with written notice of termination within fifteen (15) days of Customers receipt of the Companys notice regarding such change in Service offerings, features, rates and/or charges. Customers termination under this section will be effective sixty (60) days from the date the Company receives such notice. If Customer does not provide the Company with a notice of termination within the permitted time period, Customer will be deemed to have accepted the changed price, rate, feature or offering. The contractual relationship between the Company and Customer for the provision of Enterprise Connection Service shall be governed by the following order of precedence: (a) provisions in this Agreement that expressly apply in lieu of, or that apply in addition to, provisions contained in the Guide and (b) provisions contained in the Guide. The Company may substitute facilities or equipment used to furnish the Service, substitute comparable service, or discontinue the Service, at any time.

I. Customer Support Services charges apply.

V. TERMS AND CONDITIONS

A. CONDITIONS OF PROVIDING EMERGENCY 911 SERVICE. Customer is responsible for complying with all applicable emergency calling service laws. The ability to access an appropriate PSAP with the Service depends on the type, configuration and location of the phone used. Customer has the option of using three different types of phones (a) a SIP phone provisioned and used in a fixed, identified location (a Fixed SIP phone), (b) a SIP phone provisioned as Mobile i.e., subject to being used in more than one location, and (c) a traditional non-SIP phone provisioned and used in a fixed, identified location. In all cases, the Service cannot support the delivery of the callers station level phone number and specific station location. Furthermore, much like access to Emergency 911 Service via traditional PSTN local service, access to a PSAP will be unavailable if Customers access circuits or local gateway fails. Customer will notify all end-users of the Service that 911 access to an appropriate PSAP is not available using a Mobile SIP phone and that 911 access to a PSAP is limited as described in this section when using a Fixed SIP phone or a traditional, non-SIP phone.

1. Mobile SIP Phones. Because the location of a Mobile SIP phone user cannot reliably be determined from its billing phone number[1] (which is how 911 calls ordinarily are routed to the appropriate local PSAP), 911 calls from a Mobile SIP phone cannot be routed to the appropriate PSAP. As a result, when 911 is dialed on a Mobile SIP phone, the call will be blocked.

2. Fixed SIP Phones. When 911 is dialed on a Fixed SIP phone, the call will be routed to the appropriate PSAP based on the billing telephone number assigned to the Fixed SIP phone. If moved to a new fixed location, a Fixed SIP phone may need to be reconfigured in order for a 911 call to be routed to the appropriate PSAP.

3. Traditional Non-SIP Phones (Standard Phones). When 911 is dialed on a traditional, non-SIP (i.e., standard) phone used with the Service, the call will be routed to the appropriate PSAP based on the billing telephone number assigned to the phone.

B. DISCLAIMER OF CERTAIN DAMAGES WITH RESPECT TO EMERGENCY 911 SERVICE

1. 911 SERVICE IS OFFERED SOLELY AS AN AID IN CONTACTING AN APPROPRIATE PSAP IN CONNECTION WITH FIRE, POLICE AND OTHER EMERGENCIES. THE COMPANY IS NOT RESPONSBLE FOR ANY LOSSES, CLAIMS, DEMANDS, SUITS OR ANY LIABILITY WHATSOEVER, WHETHER SUFFERED, MADE, INSTITUTED OR ASSERTED BY CUSTOMER OR BY ANY OTHER PARTY OR PERSON FOR ANY PERSONAL INJURY TO OR DEATH OF ANY PERSON OR PERSONS, AND FOR ANY LOSS, DAMAGE OR DESTRUCTION OF ANY PROPERTY, WHETHER OWNED BY CUSTOMER OR OTHERS, CAUSED OR CLAIMED TO HAVE BEEN CAUSED BY: (1) MISTAKES, OMISSIONS, INTERRUPTIONS, DELAYS, ERRORS OR OTHER DEFECTS IN THE PROVISION OF EMERGENCY 911 SERVICE, OR (2) INSTALLATION, OPERTAION, FAILURE TO OPERATE, MAINTENANCE, REMOVAL, PRESENCE, CONDITION, LOCATION OR USE OF ANY EQUIPMENT AND FACILITIES FURNISHING THIS SERVICE.

2. THE COMPANY ALSO IS NOT RESPONSIBLE FOR ANY INFRINGEMENT OR INVASION OF THE RIGHT OF PRIVACY OF ANY PERSON OR PERSONS, CAUSED OR CLAIMED TO HAVE BEEN CAUSED, DIRECTLY OR INDIRECTLY, BY THE INSTALLATION, OPERATION, FAILURE TO OPERATE, MAINTENANCE, REMOVAL, PRESENCE, CONDITION, OCCASION OR USE OF EMERGENCY 911 SERVICE AND THE EQUIPMENT ASSOCIATED THEREWITH, OR BY ANY SERVICES FURNISHED BY THE COMPANY INCLUDING, BUT NOT LIMITED TO, THE IDENTIFICATION OF THE TELEPHONE NUMBER, ADDRESS OR NAME ASSOCIATED WITH THE PHONE USED BY THE PARTY OR PARTIES ACCESSING EMERGENCY 911 SERVICE, AND WHICH ARISE OUT OF THE NEGLIGENCE OR OTHER WRONGFUL ACT OF THE COMPANY, CUSTOMER, ITS USERS, AGENCIES OR MUNICIPALITIES, OR THE EMPLOYEES OR AGENTS OF ANY ONE OF THEM.

C. Service Availability/Disclaimer.

1. Service Availability. Customers eligibility for Enterprise Connection Service is contingent upon receiving satisfactory results of an application analysis conducted by the Company. In addition, to receive Enterprise Connection Service, Customers Local Area Network (LAN) environment must be 10 to 100 MB switched ethernet; Customers LAN and/or Wide Area Network (WAN) must have adequate bandwidth, including Committed Information Rates (CIR), ports and access circuits, to support the minimum amount of concurrent voice and data traffic ordered by Customer; measurements of Customers WAN must indicate that the latency between calling sites does not exceed the maximum Company requirements; and Customers voice traffic must be given priority over Customers data traffic. If Customer uses a firewall, the firewall must support Session Initiation Protocol (SIP) or public addresses that can be allowed through Customers firewall via pin-holes to the Service. The Service requires SIP Signaling at Port 5060 and Real Time Transport Protocol (RTP) Traffic Port ranges greater than 1023 in order to traverse Customers firewall. Any SIP Phone and/or gateway used by Customer must be compatible with the Service as determined by the Company. Enterprise Connection Service is not available to Company Dedicated Internet Managed CPE Customers.

2. Disclaimer. The Service relies on Customers DNS server and will not be available if Customers DNS server fails. Customer is responsible for maintaining the quality and condition of its LAN, and thus, the Company is not responsible for poor quality or outages of the Service that result from the quality or condition of Customers LAN. The Company reserves the right to reject any order for Services for any reason, including without limitation the inability or impracticality of providing such Service in a particular geographic area in which the Company does not have sufficient presence, capacity, corporate infrastructure or network technical infrastructure to effectively support the requested Service.

3. Service Availability/Disclaimer specific to Enterprise Connection Line-based Service.

3.1 In addition to satisfying the service availability conditions set forth in Section V., Heading C, Enterprise Connection Line-based Service is subject to the following availability conditions: Customers site must be in a geographical area in the United States where Enterprise Connection Line-based service is available; the Service is not available at Customer sites using a PBX; all conditions associated with the applicable Transport Service(s) must be satisfied.

3.2 The following disclaimers apply to Enterprise Connection Line-based Service in addition to those set forth in Section V., Heading C: Customer understands that use of the Line-based Service is restricted in the following manner: (i) For each Customer location, only one (1) T-1 line may be utilized; (ii) At any given time, Customer may only place as many concurrent calls as it has purchased individual lines; (iii) Customer may not modify the Company installed design and/or configuration without the previous written consent of the Company; (iv) Customer may not utilize auto-dialers or any similar type of device in connection with the Service; and (v) Customer may not utilize the Service in any call center environment or in connection with any similar such application. CUSTOMER EXPRESSLY ACKNOWLEDGES THAT ANY VIOLATION OF THE FOREGOING RESTRICTIONS ON ITS USE OF THE SERVICE WILL RESULT IN THE IMMEDIATE TERMINATION OF THE SERVICE BY THE COMPANY. The Company will install the Line-based Service from the point of the local exchange carriers smart-jack to Customers premises.

D. SERVICE EQUIPMENT

1. Provision of Service Equipment.

2. Maintenance of Service Equipment.

3. Return of Service Equipment.

E. Customer Obligations.

In addition to the other obligations of Customer contained within Customers Agreement, as supplemented by this Guide, Customer will be responsible for the following obligations:

1. Customer-Obtained Facilities. Except as otherwise expressly stated herein, Customer is responsible for obtaining, installing, and maintaining all equipment (including, but not limited to, SIP Phones and Cisco gateways), software, wiring, power sources, telephone connections and/or communications services necessary for inter-connection with the Companys network or otherwise for use in conjunction with the Service (Facilities). Customer is responsible for ensuring that such Facilities are compatible with the Companys requirements and that they continue to be compatible with subsequent revision levels of Company-provided equipment, software and services. The Company is not responsible for the availability, capacity and/or condition of any Facilities not provided by the Company. Customer may purchase equipment necessary for use of the Service from the Company under the terms of a separate agreement.

2. Security. Customer shall, at its own expense, take all reasonable physical and information systems security measures necessary to protect all equipment, software, data and systems located on Customers premises or otherwise in Customers control and used in connection with the Service, whether owned by Customer, the Company, or the Companys subcontractors. Customer acknowledges and agrees that the Company is not liable, either in contract or in tort, for any loss resulting from any unauthorized access to or alteration of, theft, destruction, corruption, or use of, Facilities used in connection with the Service.

3. Customer Sites. Customer agrees to provide the Company and its subcontractors and their respective employees and agents access to Customer's sites where any Service is provided (including access to associated equipment) as necessary for the Company and its subcontractors to provide the Service.

If Customer does not provide such notice, the implementation activities will be deemed to be accepted by Customer. Upon Customers acceptance of the implementation of Enterprise Connection Service, any maintenance or management of Customers network is the sole responsibility of Customer.

5. Post-Implementation Trouble Management. Upon Customers acceptance of the implementation of Enterprise Connection Service, Customer will be fully responsible for any maintenance and management of Customers network. Customer may enter into separate agreements with the Company for such services. Should Customer require Company assistance in post-implementation trouble management, the Company is limited to assisting with the following activities, pursuant to Customers Agreement, as supplemented by the respective section of this Guide:

5.1 Clear any troubles within the Company network up to the point of demarcation between Customer site and the Company network. In order to clear troubles up to the point of demarcation, the Company may request Customer make available to the Company the router vendor or a qualified Customer employee for the purpose of trace route testing. Should Customer have ISDN PRI Service from the Company to interoperate with their Enterprise Connection Service, the vendor or a qualified Customer employee who has technical expertise to include knowledge of ISDN D channels, ISDN layers 1, 2 and 3, ISDN circuit configurations on Customers Gateway Router and advanced telephony principals must be provided.
