On 14 January 2013, Wai Yuen Tong Medicine Holdings Ltd. entered into the Master Sales Agreement with Wang On Management Limited for the sales of the Group's Products to WOM (for itself and on behalf of other members of the Wang On Group) for a term with retrospective effect from 1 April 2012 and until 31 March 2015. Pursuant to the Master Sales Agreement, WYTM supplies the Group's Products to WOM (for itself and on behalf of other members of the Wang On Group). The prices of the Products supplied or to be supplied by the Group to the Wang On Group will be based on the prevailing selling prices of the Products as from time to time determined by the Group and will be no less favourable to the Group than terms offered to other independent third parties customers.

Payments for the Products will be on normal commercial terms in accordance with the credit terms that the Group would typically extend to its customers. The actual amount, specification and price of the Products to be sold to WOM will be subject to individual orders placed by WOM and accepted by WYTM.
