The Peng-Lin Closing is expected to occur on the same date as the Gold Sino Closing. Each Ordinary Share is entitled to one (1) vote per share. Following the death of Mr. Chung Yao Yin's father, Mr. Yin, his mother and another successor became entitled under the laws of descent and distribution to one-third each of the Gold Sino shares formerly held by his father. On June 22, 2026, Mr. Yin's mother agreed to assign her entitlement to one-third of the Gold Sino shares to Mr. Yin.
