All shareholders must agree for business to prosper. To overcome these problems, shareholder agreements often contain rules relating to the sale and transfer of shares – to whom shares can be transferred, under what conditions and at what price. If a shareholder does not subtract all or part of his or her share of shares in cash on the date indicated, the other shareholders may acquire those remaining shares. If a cash call leads to the acquisition of new shares by a shareholder, directly or via a loan convertible into shares, the net result is the dilution of the participation of shareholders who did not participate in the cash call. Shareholder agreements provide for the right of shareholders to own, sell or transfer their shares. For example, this section may contain restrictions on actions in the event of the death of the shareholder. .
