Company shall hold Customer harmless from liability to third parties resulting from infringement by the Service of any United States patent or any copyright or misappropriation of any trade secret, provided Company is promptly notified of any and all threats, claims, and proceedings related thereto and given reasonable assistance and the opportunity to assume sole control over defense and settlement; Company will not be responsible for any settlement it does not approve in writing. The foregoing obligations do not apply with respect to portions or components of the Service (i) not supplied by Company, (ii) made in whole or in part in accordance with Customer specifications, (iii) that are modified after delivery by Company, (iv) combined with other products, processes or materials where the alleged infringement relates to such combination, (v) where Customer continues allegedly infringing activity after being notified thereof or after being informed of modifications that would have avoided the alleged infringement, (vi) where Customer’s use of the Service is not strictly in accordance with this Agreement, or (vii) that arise from Customer Data or Customer Content.

    1. Notwithstanding anything to the contrary, except for bodily injury of a person, company and its suppliers (including but not limited to all equipment and technology suppliers), officers, affiliates, representatives, contractors and employees shall not be responsible or liable with respect to any subject matter of this agreement or terms and conditions related thereto under any contract, negligence, strict liability or other theory: (a) for error or interruption of use or for loss or inaccuracy or corruption of data or cost of procurement of substitute goods, services or technology or loss of business; (b) for any indirect, exemplary, incidental, special or consequential damages; (c) for any matter beyond company’s reasonable control; or (d) for any amounts that, together with amounts associated with all other claims, exceed the fees paid by customer to company for the services under this agreement in the 12 months prior to the act that gave rise to the liability, in each case, whether or not company has been advised of the possibility of such damages.
    1. Company shall not be liable or responsible to Customer, nor be considered to have defaulted or breached this Agreement, for any failure or delay in fulfilling or performing any provision of this Agreement to the extent such failure or delay is caused by or results from any act, circumstance or other cause beyond the reasonable control of Company, including acts of God, flood, fire, earthquake, explosion, governmental actions, war, invasion or hostilities (whether war is declared or not), terrorist threats or acts, riot, or other civil unrest, national emergency, revolution, insurrection, epidemic, lockouts, strikes or other labor disputes (whether or not relating to either Party’s workforce), or restraints or delays affecting carriers or inability or delay in obtaining supplies of adequate or suitable technology or components, telecommunication breakdown, or power outage.
    1. If any provision of this Agreement is found to be unenforceable or invalid, that provision will be limited or eliminated to the minimum extent necessary so that this Agreement will otherwise remain in full force and effect and enforceable.  This Agreement is not assignable, transferable, or sublicensable by Customer except with Company’s prior written consent. Company may transfer and assign any of its rights and obligations under this Agreement without consent. This Agreement is the complete and exclusive statement of the mutual understanding of the parties and supersedes and cancels all previous written and oral agreements, communications, and other understandings relating to the subject matter of this Agreement, and all waivers and modifications must be in writing signed by both parties, except as otherwise provided herein.  No agency, partnership, joint venture, or employment is created as a result of this Agreement, and Customer does not have any authority of any kind to bind the Company in any respect whatsoever. In any action or proceeding to enforce rights under this Agreement, the prevailing party will be entitled to recover costs and attorneys’ fees. All notices under this Agreement will be in writing and will be deemed to have been duly given when received if personally delivered; when receipt is electronically confirmed if transmitted by facsimile or e-mail; the day after it is sent if sent for next day delivery by recognized overnight delivery service; and upon receipt, if sent by certified or registered mail, return receipt requested.  This Agreement shall be governed by the laws of the Commonwealth of Massachusetts without regard to its conflict of laws provisions.

Exhibit B: Service Level Terms

The Services shall be available 99.5%, measured monthly, excluding holidays and weekends and scheduled maintenance.  If the Customer requests maintenance during these hours, any uptime or downtime calculation will exclude periods affected by such maintenance.  Further, any downtime resulting from outages of third-party connections, utilities, or other reasons beyond the Company’s control will also be excluded from any such calculation. Customer’s sole and exclusive remedy, and Company’s entire liability, in connection with Service availability, shall be that for each period of downtime lasting longer than one hour, Company will credit Customer 5% of the Monthly Service fees for each period of 30 or more consecutive minutes of downtime; provided that no more than one such credit will accrue per day.  Downtime shall begin to accrue as soon as Customer (with notice to Company) recognizes that downtime is taking place, and continues until the availability of the Services is restored. In order to receive downtime credit, the Customer must notify the Company in writing within 24 hours from the time of downtime, and failure to provide such notice will forfeit the right to receive downtime credit. Such credits may not be redeemed for cash and shall not be cumulative beyond a total of credits for one (1) week of Service Fees in any one (1) calendar month in any event.  The company will only apply a credit to the month in which the incident occurred. Company’s blocking of data communications or other Service in accordance with its policies shall not be deemed to be a failure of Company to provide adequate service levels under this Agreement.

Exhibit D: Tahoe LMS MAU Overage Policy

This policy outlines the procedure for billing customers who exceed the Monthly Active User (MAU) limit of their current plan. Our aim is to ensure accurate and transparent billing for MAU overages in accordance with the terms of the customer agreement.


This policy applies to all customers subscribed to a tiered MAU plan with Appsembler.

Definition of MAU

An MAU is defined as a registered user who interacts with the courseware in any given month.

Overage Determination

1. Monthly Assessment: At the end of each calendar month, Appsembler staff will compile a report of the total number of MAUs for each customer account.

2. Plan Confirmation: We will verify the number of MAUs included in your plan and the corresponding price per MAU based on your subscription tier.

3. Overage Calculation: If the actual number of MAUs exceeds your plan’s quota, an overage fee is applicable. The formula for calculating this fee is:

Overage Fee = (Actual MAUs – Included MAUs) × Price Per MAU × 1.5.

Billing and Communication

1. Billing Update: The overage fee will be updated in our billing system and charged via ACH in the subsequent month, providing a Net30 payment term.

2. Customer Notification: Customers will be notified of the overage through their preferred communication method, along with a detailed usage breakdown and the corresponding overage fee.

3.Transparency: The billing system will reflect the overage charge as a separate line item. This ensures clarity and transparency in billing practices.

Support and Customer Engagement

1. Customer Support: We offer assistance in understanding overage fees and, if necessary, will discuss potential plan upgrades to better accommodate higher MAU usage.

2. Queries and Disputes: Any customer queries or disputes regarding overage fees will be documented and resolved in accordance with company policies.

Privacy and Data Security

All customer data related to MAU calculations and billing will be handled in strict compliance with our privacy policies.

Ongoing Review and Updates

This policy is subject to periodic review to ensure its effectiveness and relevance.

Note to Customers

We encourage you to regularly review your MAU usage. Upgrading to a higher tier may be more cost-effective if your usage consistently exceeds your current plan’s MAU quota.
