HLK Platform Entry Guidelines

1. The platform is merely a "third-party service provider offering information release, transaction matching, and technical support". By entering the platform, enterprises and purchasers acknowledge that the platform has the "right to promote" the enterprise and its products, the right to provide "matching services", and the "exclusive cooperation right", etc. The promotion expenses before the order is formed will be borne by the platform. Once the order is successfully signed, the enterprise is willing to bear the promotion expenses in one lump sum.

2. Exclusive Authorization Clause For enterprises that the platform starts to match: 1. When the platform introduces a purchaser for the first time and provides the enterprise with the purchaser's demand list and contact information; 3. When the platform provides the purchaser and conducts matching;

4 When the purchaser and the enterprise have their first online meeting and exchange contact information. Meeting any of these conditions will be regarded as the enterprise and the purchaser entrusting the platform with exclusive authorization. The enterprise promises not to entrust other third parties for cooperation with this specific purchaser or this project. If such behavior occurs, it will be regarded as "jumping the queue". Purchasers have read this clause when registering. The platform truthfully discloses the enterprise's exclusive cooperation terms to the distributors. If the purchaser continues to contact and trade with the enterprise, it is regarded as accepting the exclusive authorization. If the purchaser bypasses the platform to trade with the enterprise that has been granted exclusive authorization, they need to pay the platform service fee. The platform's first effective introduction and facilitation of the first substantive contact with a specific purchaser is recognized as "effective introduction" and "substantive contact". Purchasers and enterprises are prohibited from bypassing the platform for direct transactions. Orders signed by the purchaser and the enterprise with exclusive authorization are recognized as the effectiveness of the platform's promotion. The enterprise is willing to pay the platform's promotion fee, service fee, etc.
