ITEM BACKGROUND: ATT recently significantly expanded availability of their ATT Business Class Fiber, which has proven to be responsive and resilient for our existing 5 locations. With approval of this item, we will cancel ATT MPLS and Comcast ENS circuits at the attached 19 locations and replace them with 20 new ATT Business Class fiber circuits given the significant bandwidth increases possible, the capabilities of this solution and the significant cost savings. The list of circuit locations and user departments as well as current and projected costs is included in the attached spreadsheet.

The HSIA-E Service Guide consists of the following Parts: • Service Description (SD) • Service Level Agreements (SLA) • Promotions (PROMO) • Pricing (P) In addition, specified portions of the General Provisions apply. Cross References Service Description Service Level Agreements Pricing Promotions (PROMO) Service Description SD-1. General Section Effective Date: 01-Jan-2018 HSIA-E Service is a connection to the Internet. The HSIA-E connection traverses the facilities owned by AT&T in certain geographic areas or the access network of the local AT&T supplier. SD-1.1. HSIA-E Service Types Section Effective Date: 08-Apr-2022 The types of HSIA-E service that AT&T offers are: • Broadband II, which offers both symmetric and asymmetric speed options of 25Mbps/5Mbps through 5Gbps/5Gbps over fiber. This service is available in pre-wired fiber ready buildings and over the gigabit passive optical network (GPON). Broadband II service is not distance sensitive. • Broadband, which utilizes ADSL2+ and vDSL technologies, is an asymmetric data service to the Customer's premises provided over available facilities at the location, either conditioned copper pair, a combination of conditioned copper and fiber, or all fiber. The availability of these speeds depends upon the distance from the Central Office or remote terminal. The AT&T Business Service Guide is subject to change by AT&T from time to time. See http://serviceguidenew.att.com for current version. ©2026 AT&T Intellectual Property.All rights reserved.

This document reflects the Service Guide in effect as of May 29,2026 Page 4 of 20 AT&T Business Service Guide AT&T High Speed Internet — Enterprise (HSIA-E) (formerly known as AT&T Business DSL Internet Service (DSL)) • ADSL, which is asymmetric data service to the Customer's premises provisioned over a copper pair. The Customer eligibility for these bandwidths depends upon the distance the user is from the Central Office. ADSL is offered in two ways: o ADSL Line-share service is provided over a voice POTS telephone line at the Customer's premises. o ADSL Direct service (commonly known as dry loop or dedicated ADSL) is provided over a dedicated copper pair without any voice POTS telephone line to the Customer's premises. In lieu of a POTS number, a Fictitious Telephone Number (FTN) is assigned to the HSIA-E circuit. This service is only available using AT&T owned facilities in a specific geographic footprint (see section 1.2 for Geographic Availability). SD-2. Geographic Availability Section Effective Date: 07-Apr-2022 HSIA-E is available only in locations throughout the United States and is defined as follows: • In-Region: refers to HSIA-E provided on AT&T owned facilities within a twenty-one (21) state footprint listed below. Broadband, Broadband II, and ADSL (both Line-share and Direct) are available in-region. o Broadband and Broadband II service can be ordered in the following twenty-one (21) states (AL, AR, CA, FL, GA, IL, IN, KS, KY, LA, MI, MO, MS, NC, NV, OH, OK, SC, TN, TX, and WI), subject to availability. o ADSL Service (Line-share and Direct) (Grandfathered)* can be ordered in the following twelve (12) states (AR, CA, IL, IN, KS, MI, MO, NV, OH, OK, TX, and WI), subject to availability. *ADSL is grandfathered effective October 1, 2020. New and change orders will not be accepted after this date. Cross References SD-4. HSIA-E Service Plans SD-2.1. Service Availability Information Section Effective Date: 12-Apr-2019 Service availability depends on site address. Customer is required to check availability of specific sites for all HSIA-E types. AT&T will provide service availability information to the Customer, as a convenience to the Customer in determining the possible availability of the service at specific locations.

Customer assumes the risk related to any Customer modifications to the default firewall settings. Customer understands that AT&T will make commercially reasonable efforts to provision HSIA- E. However, provisioning of Service is contingent upon the availability of local access to Customer's location. If local access facilities are not available to AT&T, then Service will not be provisioned. Customer understands that the actual bandwidth delivered is not determined until the time of service installation. The actual bandwidth may be different than the estimated bandwidth provided to Customer by AT&T at the time of ordering the service. The speeds quoted are maximum upload and download speeds and may vary during the Service Period. Customer understands that even after the HSIA-E circuit is provisioned and operational, certain conditions may impact the quality and use of the line. Service and speed may be impacted if it is determined that the loop length exceeds the required distance from the Central Office or terminating equipment to support the desired bandwidth. In addition, environmental issues such as quality of the local access connection, interference from other services at the site, or high frequency sources conflicting with the transmission may deteriorate the quality or speed of the HSIA-E circuit resulting in reduced throughput. AT&T will undertake reasonable effort to restore the original quality or speed, but restoration is not guaranteed and the line may be deemed technically not feasible. If the HSIA-E circuit is deemed technically not feasible, the customer will be asked to disconnect the circuit at no cost or without penalty. If the customer chooses to continue to use the circuit, after it is deemed technically not feasible, Customer understands that the line will not be supported by AT&T from a maintenance perspective. Customer acknowledges that in the event of a trouble, Customer is responsible for on-site cooperative testing with AT&T HSIA-E Customer Care to assist in the diagnosis of the trouble.

This document reflects the Service Guide in effect as of May 29,2026 Page 6 of 74 AT&T Business Service Guide AT&T Service Guide: General Provisions&Glossary AT&T Service Guide: General Provisions & Glossary General Provisions Section Effective Date: 09-Jan-2012 The following General Provisions apply with respect to the AT&T services covered by a Service Guide included in the Service Guide Library at htti):Hserviceguidenew.att.com, except as otherwise specified below or as otherwise provided in a specific Service Guide Title or in Customer's Service Agreement. GP-1. Applicability of General Provisions Section Effective Date: 20-Dec-2006 Specific sections of the General Provisions apply with respect to specific Services as described within each Section and as otherwise noted in the Applicability of Section below. GP-2. Payment, Billing, and Calculation of Charges GP-2.1. Multiple Location Billing Option Section Effective Date: 05-Dec-2025 Under the Multiple Location Billing (MLB) Option, AT&T will provide separate bills for multiple locations designated by Customer as MLB locations. Customer is responsible for: (a) all orders to add, delete, or change service at MLB locations; (b) payment of all charges billed to MLB locations; and (c) compliance by Users at each MLB location with the terms of Customer's Service Agreement. Usage and/or charges from all MLB locations will be used to determine any applicable discount, and to retire any applicable minimum volume or revenue commitment. GP-2.2. Fractional Charges and Credits Section Effective Date: 15-Mar-2023 Computing Charges or Credits for a Partial Month When a monthly charge applies for a portion of a billing month (whether due to an installation or discontinuance of service during the billing month, a rate change during the month, or otherwise), the partial charge (or credit) is calculated based on a daily rate (1/30th of the monthly charge) and number of actual days remaining in the month after the event giving rise to the partial charge. Example: If the billing month starts on the first day of the calendar month and a circuit is disconnected on March 18, a credit applies equal to 1/30th of the monthly charge multiplied by the number of days remaining (13) in the month. If the rate applicable to another circuit changes on March 24, a credit will apply equal to 1/30th of the old monthly charge multiplied by the days remaining (8, including the 24th) in the month, and a partial monthly charge will apply equal to 1/30th of the new monthly charge multiplied by the days remaining (8) in the month. Daily or Hourly Rates The AT&T Business Service Guide is subject to change by AT&T from time to time. See http://serviceguidenew.att.com for current version. ©2026 AT&T Intellectual Property.All rights reserved. AT&T,the AT&T logo and all other AT&T marks contained herein are trademarks of AT&T Intellectual Property and/or AT&T affiliated companies. This document reflects the Service Guide in effect as of May 29,2026 Page 7 of 74 AT&T Business Service Guide AT&T Service Guide: General Provisions&Glossary For Service Components with a minimum payment period of one day or one hour, the rate that is in effect at the beginning of the period during which the Service Component was furnished applies for the duration of the minimum payment period. Example: A Service Component for which a daily rate applies is furnished beginning at 4 PM on July 31. At 12:01 AM on August 1, a new rate becomes effective. The rate in effect on July 31 applies for the minimum payment period that expires at 4 PM on August 1. Thereafter, the new rate applies. GP-2.3. Refunds of Credit Balances Section Effective Date: 15-Mar-2023 If there is a credit balance on a closed Customer account, AT&T may apply such credit balance against any past due balances on any other Customer accounts associated with the same Service Agreement or service as the closed account. Customer will be entitled to a cash refund of any remaining net credit balance. GP-2.4. Application of Per Minute Rates Section Effective Date: 05-Dec-2025 When a Service Guide includes usage charges stated as per minute rates, and also sets forth an Initial Period and Additional Period, the per minute rate is prorated based on an Initial Period and an Additional Period. The usage charge for the Initial Period is equal to the per minute rate, multiplied by the number of seconds in the Initial Period divided by 60. The usage charge for each Additional Period is equal to the per minute rate, multiplied by the number of seconds in the Additional Period divided by 60. For example: If the per minute rate is $0.09, the Initial Period is 18 seconds, and the Additional Period is 6 seconds, then the usage charge for the Initial Period is $0.027 ($0.09 x 18/60) and the usage charge for each Additional Period is $0.009 ($0.09 x 6/60). The usage charge for each call is equal to the Initial Period rate added to the product of the Additional Period rate multiplied by the number of full or partial Additional Periods by which the call duration exceeds the Initial Period. Applicability of Section • Applies to any Service having usage charges in per minute rates and subject to a rate formula based on an Initial Period and Additional Periods. • Applies to some but not all Contact Management Services (i.e., applies to Interactive Voice Services but not to VoiceTone). GP-2.5. Application of Time of Day/Day of Week Rates Section Effective Date: 05-Dec-2025 When a rate varies according to the time of day or day of the week the service is provided (i.e., peak/off-peak rates, standard/discount/economy rates), the time and day at Customer's location is used to determine the rate applicable for the full duration of the time the service is provided.

If a Bloomberg L.P. — New York Composite average exchange rate is not available, AT&T will calculate the invoice amount using the currency exchange rate established for such currency conversions published by the Central Bank (or a similarly designated institution deemed acceptable by AT&T as a source for currency exchange rates) for the country in which the invoice is delivered as of the date indicated on the Invoice.

Upon notice to Customer, AT&T may recover any Toll-Free Number that is not placed in actual and substantial use. • Using Toll-Free Service for "mass calling applications," without a prior written agreement between Customer and AT&T expressly allowing specifically described "mass calling applications." A "mass calling application" is an application that generates over ten million calls to a Toll-Free Number in any time period of 2 hours (including, for example, mass- volume inbound calling applications associated with events, promotions, polls, surveys, television, or radio shows). • Failure to obtain access lines with capacity adequate to handle Customer's use of a Service. • Artificially stimulating calling or other usage volumes to: (a) any number advertised or intended for accessing information programs and services, including but not limited to chat lines or Audiotext programs ("Audiotext"); (b) routing codes or international area or city codes reserved or used by the subject telecommunications administration for Audiotext; (c) special routing codes, telephone numbers, or locations for which the cost of call origination or termination is higher than that incurred for originations or terminations to other parts of the same jurisdiction or locale; or (d) telephone numbers or service arrangements where the party causing the artificial stimulation derives revenues or other financial benefit from, or is compensated based upon said calling or other usage volumes in a capacity other than as a communications carrier, or if acting as a communications carrier, earns a surcharge or similar increment (or an entity with a common financial interest with the party stimulating the traffic earns a surcharge or similar increment) merely by virtue of the origination or termination of such calls. Such artificial stimulation may include, but is not limited to, use of electronic or other automatic means to generate such call volumes, or hiring of agents or contractors principally to make calls or otherwise generate usage to such numbers or types of services, but does not, without more, include advertising or promotion of Audiotext or similar programming to stimulate calling by third parties with no financial or other beneficial interest in the service or called program. • Using service provided by AT&T to generate calls with the intent or effect of creating a disparity (across any Customer account) between the costs to AT&T of originating and/or terminating access and the pricing of long-distance service provided by AT&T. • Sending calls identified as Mobile Terminated Calls, or as another termination type to which a surcharge or other differential rate for termination applies, when the called station or termination point is not in fact Mobile Terminated, or the termination type as to which the surcharge or other differential rate applies.

AT&T may disclose to third-parties Customer information regarding the quantity, technical configuration, type, origination, destination, or number of calls, communications, or transmissions of services to the extent needed to investigate suspected misuse, fraudulent, abusive, and/or unlawful use of, or subscription to, AT&T service (including disclosing information regarding Prohibited Traffic).

Automatic Number Identification/Charge Number Service Section Effective Date: 05-Dec-2025 When Customer obtains a telephone subscriber's information through Automatic Number Identification or Charge Number Service, Customer must comply with the regulations adopted by the Federal Communications Commission regarding the use and sale of information derived from Automatic Number Identification or Charge Number Services, including the following: • Customer is permitted to use the telephone number and billing information for billing and collection, routing, screening, and completion of the originating telephone subscriber's call or transaction, or for services directly related to the originating telephone subscriber's call or transaction; • Customer is prohibited from reusing or selling the telephone number or billing information without first: (a) notifying the originating telephone subscriber; and (b) obtaining the affirmative consent of such subscriber for such reuse or sale; and • Customer is prohibited from disclosing, except as permitted by above, any information derived from the Automatic Number Identification or Charge Number Service for any purpose other than: (a) performing the services or transactions that are the subject of the telephone subscriber's call; (b) ensuring network performance security and the effectiveness of call delivery; (c) compiling, using, and disclosing aggregate information; and (d) complying with applicable law or legal process.

GP-10.6. Access Arbitrage Section Effective Date: 05-Dec-2025 Using any service provided by AT&T in connection with Access Arbitrage is considered an abuse and is prohibited. Access Arbitrage is a scheme or device to profit by exploiting differences between the cost of originating or terminating access (as charged to interexchange or international carriers) and the pricing of long-distance service provided by AT&T. Access Arbitrage includes: • using switching equipment or a call processing system (such as a prepaid card, calling card, or teleconferencing platform) to segregate calls and systematically route to AT&T calls that are characterized by a greater discrepancy between the access costs and the price charged by AT&T; • using AT&T long distance telephone services (such as AT&T SDN OneNet Service, Virtual Telecommunications Network Service or AT&T BVoIP Service) as a substitute for, or to avoid, originating or terminating switched exchange access obtained from local exchange providers, for the origination or termination of domestic calls originated over the network of another carrier (through 1+ access, special access, carrier access code dial around, or otherwise); • Routing calls through a call processing system such that the percentage of High Cost minutes routed to AT&T using the service is more than 11.1%; • Segregating calls within another carrier's network or a call processing system to systematically route calls to AT&T where the access costs exceed the price of long distance service provided by AT&T; and • Transporting intrastate or intra-country traffic into a different state or country in order to cause the traffic to be rated by AT&T at a lower rate than would otherwise apply. If AT&T reasonably suspects that a service provided under this Service Guide is being used in connection with Access Arbitrage, Customer will permit AT&T to inspect the premises from which the calls originate (as reflected in AT&T's records) and will cooperate reasonably with AT&T's efforts to investigate the manner in which calls are being routed to AT&T. For purposes of this provision: • "High Cost Calls" are calls that originate or terminate at numbers for which the originating or terminating switched exchange access cost per minute exceeds $0.025 (or the benchmark rate for Competitive Local Exchange Carrier's interstate switched exchange access services established by the Commission, if lower than $0.025). • The originating or terminating switched exchange access cost per minute will be the sum of the per minute charges imposed by the originating or terminating Local Exchange Carrier, plus the prorated portion of all other charges imposed by the originating or terminating Local Exchange Carrier for originating or terminating switched exchange access, expressed on a cost per minute basis.

This document reflects the Service Guide in effect as of May 29,2026 Page 38 of 74 AT&T Business Service Guide AT&T Service Guide: General Provisions&Glossary If the percentage of High-Cost minutes routed to AT&T using the service is more than the percentage set forth above, and AT&T's investigation shows that any such calls are originated over the network of another interexchange carrier or routed through a call processing system, then all such calls will be presumed to be Access Arbitrage. If Customer violates this provision, the Access Arbitrage Fee will apply. In addition, AT&T may immediately restrict, suspend, or discontinue Customer's use of any service used in connection with Access Arbitrage upon notice of such violation to Customer. Further, AT&T may prevent conversion to another AT&T service arrangement of any facility used to provide a service in violation of this provision. Cross References GP-4.2.6.
