A Shareholder Agreement is a legal contract among the shareholders of a company that defines their rights, responsibilities, and mutual understanding. It regulates shareholding structure, voting rights, management control, dividend policy, and transfer of shares. The agreement includes provisions on decision-making, minority protection, confidentiality, non-compete obligations, and dispute resolution. It also sets out exit options, such as buy-sell clauses, valuation methods, and procedures in case of death or insolvency of a shareholder. By clearly defining rules and expectations, a Shareholder Agreement helps prevent conflicts, ensures stable management, and protects the interests of all shareholders.
