Plus Plan Addendum

The Amplitude Plus Plan is a program whereby Customer shall pay Amplitude the Fees (as set out in Section 2 of this Addendum) for a specified event volume plus access to certain advanced behavior analytics features and email support within the Amplitude Services (the "Plus Plan").

Customer shall pay Amplitude the fees for the Amplitude Services listed on the Stripe payment checkout page when Customer purchases the Plus Plan, plus any applicable taxes (collectively, the "Fees"). The Fees for each Renewal Subscription Term (defined below) shall be the then-current Fees for the Plus Plan in effect at the time of renewal, unless Amplitude provides otherwise with at least 30 days’ notice to Customer. Customer agrees to pay all Fees in US dollars. Except as otherwise set forth herein or separately agreed between Customer and Amplitude, all Fees and Overage Fees (defined below) due hereunder shall be billed to Customer’s credit card and Customer hereby authorizes the card issuer to pay all such amounts and authorizes Amplitude (or its billing agent) to charge the credit card account for such Fees or Overage Fees, as the case may be. All payment obligations are non-cancelable and all Fees paid are non-refundable. Except as expressly set out herein, if Customer or Amplitude terminates Customer’s account or access to the Amplitude Services in accordance with the Terms or this Addendum, Customer is not entitled to a refund of any Fees already paid.

2.1 – Overages

If Customer’s use of the Amplitude Services exceeds the event volume that Customer purchased when signing up for the Plus Plan, Amplitude may, in its sole discretion: (i) invoice Customer for such excess event volume at a rate of $350 per one million events (the "Overage Fees"); and/or (ii) if Customer’s event volume exceeds 100 million events in any one month, suspend or terminate Customer’s account. From time to time, Amplitude may choose to add additional features to the Plus Plan which are subject to certain usage limits. In the event that Customer elects to use such features and such use exceeds the stated usage limits for such features, Customer may be subject to additional overage fees or other penalties as described in the terms or other documentation applicable to such features. Unless otherwise specified by Amplitude, payment for the Overage Fees is due within five (5) days of receipt of the invoice, or the Amplitude Services may be suspended or terminated.

This Addendum will commence on the Addendum Effective Date and continue until terminated as set forth below. Notwithstanding Section 5.1 of the Terms, and subject to earlier termination as provided herein, the initial subscription term shall be twelve (12) months (the "Initial Subscription Term"). If the Plus Plan is still in effect at the end of the Initial Subscription Term, Customer’s subscription shall be automatically renewed for successive terms of twelve (12) months (each a "Renewal Subscription Term" and together with the Initial Subscription Term, the "Subscription Terms"), unless either party sends notice of non-renewal at least thirty (30) days prior to the end of the then-current Subscription Term.

If either party chooses not to renew Customer’s Plus Plan subscription at the end of a Subscription Term, Amplitude may automatically downgrade Customer’s account to a Starter Plan and Customer’s access to and use of the Amplitude Services shall then be governed by the Terms, unless (i) otherwise agreed between the parties, (ii) Customer provides written notice to Amplitude that it wishes to terminate its use of the Amplitude Services and/or delete its account, or (iii) Customer’s account or access to the Amplitude Services has been terminated pursuant to the Terms and/or this Addendum.

In addition to a party’s termination rights under the Terms and Amplitude’s termination rights under Section 2.1, either party may terminate the Terms and this Addendum during a Subscription Term if the other party: (a) fails to cure any breach of the Terms and/or this Addendum within thirty (30) days of the non-breaching party’s written notice of such breach; (b) ceases to do business in the ordinary course; or (c) seeks protection under any bankruptcy, receivership, trust deed, creditors arrangement, composition or comparable proceeding, or if any such proceeding is instituted against such party (and not dismissed within sixty (60) days). If the Addendum is terminated by Customer due to a material breach by Amplitude, then Amplitude shall refund Customer on a pro-rata basis any prepaid Fees covering the remainder of the then-current Subscription Term. For the avoidance of doubt, if the Addendum is terminated as a result of a material breach by Customer, then Customer shall pay in full any outstanding Overage Fees and all other Fees prepaid by Customer are nonrefundable.

Notwithstanding the limitation of liability set forth in Section 8 of the Terms, Amplitude’s maximum aggregate liability for any and all claims and damages arising out of or related to the Amplitude Services, whether arising in contract, tort (including negligence), strict liability, statute or otherwise, shall not exceed the amount actually paid or payable by Customer to Amplitude for the Amplitude Services in the twelve (12) months prior to the act that gave rise to the liability, even if Amplitude has been advised of the possibility of any of the foregoing types of losses or damages. In no event shall either party be responsible or liable to the other party for any indirect, exemplary, incidental, punitive, special or consequential damages of any kind, regardless of the form of action, even if informed of such damages in advance.

Any failure to enforce any provision of this Addendum shall not constitute a waiver thereof or of any other provision.
