Public Offer

This document is a public offer (the "Offer") of Watcher Landmark Telecom Thailand Co., Ltd. (abbreviated as WLTT Co., Ltd., the "Company", "we") and sets out all material terms for the provision of services to individuals and legal entities (the "Customer"). The subject of the Offer is the provision by the Company of the following services: • supply and sale of professional equipment (LED screens, audio, lighting, network and POS equipment); • engineering, installation and commissioning works, maintenance; • provision of software and cloud services, including the PromptPay QR payment plugin for the Syrve (iiko) POS system; • related technical support and consulting. Acceptance of this Offer (full and unconditional acceptance of its terms) is deemed to occur upon any of the following actions by the Customer: placing an order, paying an invoice, activating a software licence key, or beginning actual use of the service. Upon acceptance, the Offer has the force of a contract.

The Company provides, in particular: • Equipment — supply of equipment according to the agreed specification and commercial proposal. • Engineering services — design, installation, configuration and maintenance of the supplied solutions. • PromptPay QR plugin — a licence to use the software plugin for accepting payments via PromptPay QR for the Syrve (iiko) POS system. • Cloud service (middleware) — QR code generation, payment processing and receipt generation. • Stripe integration — payment processing via the Stripe payment provider. • Technical support — via email and messengers during business hours.

Use of the PromptPay cloud payment service is provided on a subscription basis: • Trial — 30 days, 1 terminal — free. • Monthly — 30 days, 1 terminal — 900 ฿/month. • Business — 30 days, up to 3 terminals — 2,700 ฿/month. • Annual — 365 days, up to 2 terminals — 18,000 ฿/year. • Corporate — 365 days, up to 10 terminals — 90,000 ฿/year. Pricing formula: 900 ฿ × number of terminals × period (annual payment covers 10 months). The cost of equipment supply and engineering services is determined separately in the commercial proposal or invoice for the specific order. Current tariffs are published within the service and on wltt.asia. The Company may change the tariffs upon at least 30 days' notice to the Customer; a tariff change does not affect an already paid period.

A Company fee of 1.5% (one and a half percent) of the payment amount is charged on each successful PromptPay transaction processed through the service. • The fee is withheld automatically by the payment provider (Stripe) at the moment of the transaction. • The Company fee is non-refundable in the event of a refund to the customer. • In addition, the Stripe payment provider charges its own fee of 1.65% for processing PromptPay transactions. This fee is paid by the Customer and is independent of the Company. • The Customer's total payment processing cost is 3.15% of each transaction amount (1.5% Company + 1.65% Stripe). The subscription (a fixed fee for the plan) and the fee (a percentage of transactions) are two separate types of payment.

• The subscription is paid in advance for the entire term of the selected plan. • The 1.5% fee is withheld automatically from each payment before funds are transferred to the Customer. • Payment proceeds are credited to the Customer's bank account linked to their Stripe account, less all fees. • The cost of equipment and engineering works is paid in accordance with the terms of the relevant invoice or commercial proposal.

• Maintain cloud service availability at 99.5% (SLA). • Ensure the security of payment data processing (PCI DSS — on the Stripe side). • Provide technical support via email and messengers during business hours. • Notify the Customer of scheduled maintenance at least 24 hours in advance.

• Independently complete verification with Stripe (KYC/onboarding). • Ensure a stable internet connection at the point-of-sale terminals. • Not transfer licence keys to third parties. • Not attempt to bypass the fee system or modify the software. • Use the supplied equipment in accordance with its intended purpose and instructions.

The Company is not liable for: • delays or failures of the Stripe payment provider; • lack of internet connection on the Customer's side; • acts or omissions of the banks of the Customer's clients. The Company's maximum liability is limited to the subscription amount for the current paid period.

• Refunds to customers are made by the Customer through the Stripe Dashboard. • The Company fee (1.5%) is not refundable in the event of a refund. • Stripe charges an additional refund fee — ฿10 per operation. • A paid subscription is non-refundable after licence activation.

• The Company does not store or process customer payment data (cards, accounts) — all such data is processed by Stripe. • The Company processes: order email, amount, transaction status, order identifier. • Personal data is processed in accordance with the Privacy Policy.

• The Offer is valid indefinitely from the moment of publication. • The Customer may stop using the service by not renewing the subscription. • The Company may block access in the event of a breach of the Offer terms. • The Company may amend the terms of the Offer upon at least 30 days' notice to the Customer.
