Warranties. TDengine represents and warrants that its provision of the Cloud Services, Professional Services and Support complies with applicable law. TDengine represents and warrants that the Cloud Services will perform substantially in accordance with the Documentation. TDengine represents and warrants that it will perform Professional Services and Support in a diligent and workmanlike manner consistent with industry standards. Your exclusive remedy for TDengine’s material breach of warranty is to terminate the affected Order Form in accordance with Section 11 and receive a refund of any prepaid fees for unused Subscriptions. Except as stated in this Section, we provide the Cloud Services, Professional Services and Support on an “AS-IS” basis. To the fullest extent permitted by law, TDengine disclaims and this Agreement excludes any implied or statutory warranty, including any warranty of title, non-infringement, merchantability or fitness for a particular purpose. 9. Limitation of Liability. (a) Neither party will be liable to the other party for any incidental or consequential damages, including lost profits or business opportunities, or any special or punitive damages. (b) Except as set forth in Section 9(c), each party’s cumulative liability will not exceed the total fees payable to TDengine by Customer under this Agreement during the 12-month period before the event giving rise to the liability. (c) Nothing in this Agreement limits either party’s liability for: (i) fraud or fraudulent misrepresentation; (ii) death or personal injury caused by negligence, gross negligence or intentional misconduct; (iii) Customer’s payment obligations; or (iv) any liability that cannot legally be limited. 10. Indemnification. (a) Customer Indemnification. If a third party asserts a claim against TDengine alleging that your data or the combination of your data with other applications, content or processes infringes a third party’s rights, including any claim involving alleged infringement or misappropriation of intellectual property rights (a “Claim Against Us”), Customer will defend TDengine against the Claim Against Us at Customer’s expense and indemnify TDengine from any damages, reasonable legal fees and costs finally awarded against TDengine to the extent resulting from the Claim Against Us or for amounts paid by TDengine to settle the Claim Against Us. If we or our Affiliates are obligated to respond to a third party subpoena or other compulsory legal order or process seeking information related to your data or your use of the Cloud Services, you will also reimburse us for reasonable legal fees, as well as our employees’ and contractors’ time and materials spent responding to the third party subpoena or other compulsory legal order or process at our then-current hourly rates. (b) TDengine Indemnification. If a third party asserts a claim against Customer that the Cloud Services infringe a third party’s intellectual property right (a “Claim Against You”), TDengine will defend Customer against the Claim Against You at TDengine’s expense and indemnify Customer from any damages, reasonable legal fees and costs finally awarded against Customer to the extent resulting from the Claim Against You or for amounts paid by Customer to settle the Claim Against You. TDengine will not be obligated to defend or indemnify Customer if the Claim Against You is based on any breach of this Agreement by Customer. (c) Infringement Remedies. In addition to TDengine’s indemnity obligations, if the Cloud Services become, or in TDengine’s opinion are likely to become, the subject of an infringement claim, TDengine may at its option and expense and as Customer’s sole and exclusive remedy: (i) procure for Customer the right to make continued use of the Cloud Services; (ii) replace or modify the Cloud Services so that they become non-infringing; or (iii) terminate the Cloud Services and refund any prepaid fees for unused Subscriptions. (d) Indemnification Procedures. Each party will provide the other with prompt notice of any claim. A party’s failure to provide prompt notice to the other party relieves the party of its obligation to defend and indemnify the other party only to the extent that the failure to provide notice materially harms the party’s ability to defend the claim. The indemnifying party will have sole control of the defense of the claim, including any settlement. The indemnified party will provide the indemnifying party with reasonable cooperation in connection with the defense of the claim, and may participate in the defense at its own expense. This Section 10 sets forth each party’s exclusive remedy for any third party infringement claim. 11. Term and Termination. (a) Term and Termination. The term of this Agreement commences when you agree to an Order Form and will remain in effect until terminated in accordance with this Agreement. Either party may terminate this Agreement for convenience immediately upon notice if all Order Forms under this Agreement have expired or been terminated. Neither party may terminate an Order Form for convenience. If a party fails to cure a material breach of this Agreement within 30 days after receipt of written notice of the breach, the other party may terminate any affected Order Form.

If we suspend your right to access or use any portion or all of the Cloud Services, you remain responsible for all fees and charges you incur during the suspension and you will not be entitled to any credit or refund. We will use commercially reasonable efforts to restore your access to the Cloud Services promptly following resolution of the cause of your suspension. We may suspend or terminate your access to or use of any Beta Offering at any time and for any reason. (b) Effect of Termination.
