A shareholders' agreement (sometimes referred to in the U.S. as a stockholders' agreement) (SHA) is an agreement amongst the shareholders or members of a company. In practical effect, it is analogous to a partnership agreement. It can be said that some jurisdictions fail to give a proper definition to the concept of shareholders' agreement, however particular consequences of this agreements are defined so far. There are advantages of the shareholder's agreement; to be specific, it helps the corporate entity to maintain the absence of publicity and keep the confidentiality. Nonetheless, there are also some disadvantages that should be considered, such as the limited effect to the third parties (especially assignees and share purchasers) and alternation of the stipulated articles can be time consuming.
