THIS ADDENDUM BECOMES EFFECTIVE UPON THE EARLIER OF YOUR ACCEPTANCE OF THE AGREEMENT OR THE DATE YOU START USING CLICKHOUSE CLOUD ("ADDENDUM EFFECTIVE DATE").

EXCEPT AS OTHERWISE MODIFIED IN THIS ADDENDUM, ALL OTHER TERMS AND CONDITIONS OF THE GENERAL TERMS WILL REMAIN IN FULL FORCE AND EFFECT. ALL CAPITALIZED TERMS NOT DEFINED IN THIS ADDENDUM WILL HAVE THE MEANING GIVEN TO THEM IN THE GENERAL TERMS. ON AND AFTER THE ADDENDUM EFFECTIVE DATE, ANY REFERENCE TO THE AGREEMENT MEANS THE AGREEMENT AS MODIFIED BY THIS ADDENDUM. IN THE EVENT OF A CONFLICT BETWEEN THE TERMS OF THIS ADDENDUM AND THE TERMS OF THE AGREEMENT LESS THIS ADDENDUM, THE TERMS OF THIS ADDENDUM WILL PREVAIL FOR THE PURPOSES OF SOFTWARE.

1. Additional Definitions.

The following definitions will apply to this Addendum, where applicable:

1.1. "Open Source Software" means open source libraries, components, utilities and other open source software, included with Software.

1.2. "Software" means the ClickHouse self-managed software specified on an Order Form or provided to Customer for use in a limited free trial under the Agreement, that is made generally available by ClickHouse and deployed on Customer's premises or in Customer's account with a third-party cloud provider, including all updates and new releases thereof made generally available by ClickHouse during the applicable Order Form Term. For clarity, Software excludes ClickHouse software that Customer uses subject to an open source or open source-style license.

2. ClickHouse Provision and Customer Use of Software

2.1. License Grant. During the applicable Order Form Term, and subject to the terms and conditions of the Agreement, ClickHouse grants Customer a limited, non-exclusive, non-transferable, non-sublicensable license to: (i) install the Software in object code format on Customer's own premises or in Customer's account with a third-party cloud provider; (ii) use the features of the Software at the subscription tier (if applicable) purchased by Customer, as set forth on the applicable Order Form; and (iii) permit Authorized Users to use the Software, in each case solely for Customer's internal business operations.

2.2. Delivery and Acceptance. ClickHouse delivers all Software electronically. Software shall be deemed "delivered," and the Order Form Term of such Software shall commence on the date that ClickHouse makes the Software available for download to Customer and provides any applicable license key. Upon request from ClickHouse, Customer shall provide ClickHouse with an acknowledgement of delivery of the Software (email sufficient). The Software will be deemed to have been accepted by Customer upon delivery.

2.3. Open Source Software. Customer's use of any Open Source Software is subject to the applicable open source license, which may set forth terms and conditions that are in addition to or different from those set forth in the Agreement, but which will not restrict the license rights granted to Customer in Section 2.1 of this Addendum, and which may contain additional rights.

2.4. Additional Restrictions on Use. Customer agrees not to: (i) copy or use Software in any manner except as expressly permitted in the Agreement and applicable Order Form; (ii) circumvent the limitations on use of Software that are imposed or preserved by ClickHouse, including those that may be enforced through an applicable license key; (iii) alter or remove any notices in the Software; or (iv) make available to any third party any analysis of the results of operation of Software, including benchmarking results, without the prior written consent of ClickHouse.

3. Usage Limitations and Compliance Monitoring

3.1. Monitoring Usage Limitations. An Order Form may impose limitations on Customer's use of the Software, which Customer may be capable of exceeding ("Usage Limitation"). ClickHouse may monitor Customer's compliance with Usage Limitations using ClickHouse's own resources, such as server logs and similar records. If ClickHouse cannot determine Customer's compliance with a Usage Limitation solely with reference to ClickHouse's own resources, ClickHouse may reasonably request in writing that Customer provide a report to ClickHouse concerning Customer's compliance with the Usage Limitation. Customer shall provide such report to ClickHouse within thirty (30) days after receiving the request.

3.2. Excess Usage. Customer shall promptly notify ClickHouse if Customer's use of the Software exceeds any Usage Limitation. Customer shall include in such notice the amount by which Customer has exceeded the Usage Limitation and the date on which it first exceeded the Usage Limitation. Customer shall be billed for such usage through the remainder of the applicable Order Form Term, and Customer agrees to pay such additional fees in the manner provided in the Agreement.
