What are the legal implication of the shareholder?

Angel, Leena, Joe and Lee incorporated a company in 2000 called Shiny Stars Sdn. Bhd. They hold all shares in the company, each contributing $200K to the initial capital. In return, each of them was issued 200 shares. Last year, Angel gave an unsecured personal loan of $500K to the company as it was facing financial distress. Last week, Leena, Joe and Lee passed a resolution to wind up the company. The company has no other creditors apart of Angel. It is now estimated that the value of the assets worth $400K. Angel contends that the amount $400K should be returned to her as the company has yet to pay her money. She is also of the view that the shortfall of $100K is to be personally repaid by all four shareholders in equal proportions. Meanwhile, Leena, Joe and Lee argue that the amount of $400K should be returned to the four shareholders in equal proportions. They are of the view that the company is not legally obliged to repay the debt owed to Angel as the loan was given to the company in her capacity as a shareholder.
