End-of-Life Policy

Overview

Due to factors such as market demand, technological innovation, development, and replacement by products with richer functionalities, all products have a commercial lifecycle. After a product reaches its end-of-life, YashanDB will cease its market supply and standard service support. Considering the potential impact of product end-of-life on customers' businesses, Yashan Technology Co., Ltd. ("Yashan") has established a unified End-of-Life Policy to help customers better manage the transition and to inform them of other quality products and services that may continue to be available.

This End-of-Life Policy applies to software sold independently by Yashan, as well as to combined hardware-software integrated products sold by Yashan. This policy does not apply to products that have already reached their end-of-life. Yashan assumes no responsibility or obligation for circumstances not covered by this policy.

Detailed Policy Guidelines

1.Typically, Yashan will provide at least six (6) months' notice prior to the End-of-Manufacturing (EOM) date. Yashan Technology Co., Ltd. reserves the right to issue any announcements or notifications regarding product lifecycle status through its official website (https://www.yashandb.com/service, hereinafter referred to as "Official Channels"). Customers have an obligation to continuously monitor information published on the Official Channels. Such notifications shall be deemed effectively delivered to all relevant customers on the date of publication on the Official Channels.

2.As of the product's EOM date, Yashan will no longer accept new orders for that product.

3.Within one (1) year after the EOM date, customers may contact Yashan's business department. Yashan will decide whether to enter into a new service contract with the customer and determine the contract terms based on the then-effective product and service policies, resource availability, and commercial conditions. After one (1) year post-EOM, Yashan will, in principle, only accept renewals of existing service contracts.

4.For maintenance service contracts signed prior to the EOM date, customers may apply for renewal within five (5) years after the EOM date. Yashan has the right to decide whether to approve the renewal and under what conditions, based on its then-current service capabilities, resource availability, and commercial assessment. Any renewal must be based on a renewal plan provided by Yashan at that time and accepted by the customer. Even if renewed, the final service term for the product shall not exceed the announced End-of-Service & Support (EOS) date.

5.The Yashan technical support team will continue to provide technical support services for the product for a period of five (5) years from the EOM date, in accordance with the terms of the then-effective maintenance service contract. The specific service content and standards shall be as explicitly stipulated in said maintenance contract.

6.For products that have been EOM for more than five (5) years, Yashan will no longer provide maintenance and support services. As of the EOS date or the maintenance service end date agreed upon by both parties (whichever is later), all of Yashan's service and support obligations for the relevant product shall terminate. Thereafter, unless the parties separately sign a paid service contract, Yashan has no obligation to provide any support and shall not be liable for any malfunctions, data loss, or customer losses that may occur with the product. If Yashan, based on its own technical capabilities, resource availability, and commercial judgment, voluntarily decides to provide paid technical consultation or support to individual customers, the scope, content, duration, and fees for such services shall be determined solely by Yashan and require a separately signed written agreement. Under no circumstances does Yashan make any warranties regarding the results or effectiveness of such services, nor shall it bear any legal or compensatory liability.

7.Rules for software version maintenance support services:

a.Within five (5) years after a software version's EOM date (i.e., before its End-of-Full-Service date), for software defects and security vulnerabilities reported through the website, Yashan will provide problem identification and repair services according to the relevant service contract.

b.Before a software version reaches its EOS date, customers are advised to upgrade to the latest version.

c.After a software version reaches its EOS date, Yashan will cease providing any services for that software version, including no longer patching software defects and security vulnerabilities. Customers may need to upgrade to a new software version to continue receiving the aforementioned maintenance support services.

8.Notice to partners reselling Yashan products (if applicable): Partners are obligated to ensure that their sub-distributors and end-users are aware of and understand all product lifecycle information published through Yashan's Official Channels. The partner shall bear full responsibility independently if any third party (including but not limited to sub-distributors, end-users) raises claims, suffers losses, or encounters any disputes due to the partner's failure to fulfill the aforementioned notification obligation; if this causes Yashan to suffer any losses (including but not limited to compensation, settlement fees, legal fees, litigation costs, etc.), the partner shall fully compensate Yashan.

Policy Effectiveness and Modifications

The revised policy will become effective immediately upon publication on the Official Channels, without prior separate notice. Continued use of the products by the customer shall be deemed acceptance of the revised policy.

Textual Validity

This policy is written in Chinese. In case of any discrepancy between the English version and the Chinese version of this policy, the Chinese version shall prevail. If there is any inconsistency between this policy and specific product purchase contracts, service contracts, etc., signed between the customer and Yashan (collectively referred to as "Specific Contracts"), the explicit terms of the Specific Contracts shall prevail; for matters not stipulated in the Specific Contracts, this policy shall apply.
