Shareholder agreements are practically in companies where there is a minority shareholder whose interests can be ignored by being put in a minority by the other shareholders, especially when they hold less than 25% of the shares. A shareholder contract serves to protect against an undesirable imbalance in control or long and damaging conflicts within a company. Aspects of corporate governance, for example. B where a party offers an offer to purchase the business or the terms and conditions of sale of shares, may be detailed. Powers may be granted to different shareholders who would normally be missing from a class of shares, for example. B to a minority shareholder the power to appoint a director or to complex preferential details when liquidating an undertaking. The “Russian Roulette” option is a variation of a put and reciprocal call option. The party making the offer at an impasse may give notice to the other party inviting the receiving party to buy its shares or, alternatively, to sell the beneficiary`s shares to the person making the offer at the fixed price. The aim is to ensure the offer of a fair price at which the offering party is also willing to buy and sell. This would only be appropriate for companies with two shareholders with the same financial capacity, so one party could afford to buy the other at the appropriate time. . . .
