第1题

Zhao, Qian, Sun and Lee were four shareholders of a limited liability company specialising in bio-technology, each holding 25% of the shares of the company.

Several months later Qian intended to transfer his shares to a listed company for profit and sent notices to the other three shareholders asking for their consent. Zhao agreed and also expressed his willingness to buy Qian’s shares if the price was reasonable. Sun disagreed and claimed his right of priority to buy Qian’s shares. However, Zhao and Sun could not reach an agreement as to the proportion of shares to buy. Lee kept silent upon receipt of the notice.

Since Sun offered a price lower than that of the listed company, Qian entered into a contract to sell his shares to the listed company, which caused a dispute among the four shareholders. Under such circumstances, Lee decided to leave the company and requested the company to purchase his shares.

Required:

In accordance with the relevant provisions of the Company Law:

(a) State how Zhao and Sun’s failure to reach an agreement on the proportion of shares to purchase should be dealt with. (2 marks)

(b) State whether Lee’s request for the company to purchase his shares should be upheld if the dispute was brought to court. (2 marks)
