An Option Agreement is a legally binding contract that grants one party (the optioned) the right, but not the obligation, to purchase or lease certain assets from another party (the option or) at a predetermined price and within a specified period of time. It is commonly used in real estate, finance, and other business contexts. There are two types of Option Agreements: call options and put options. A call option gives the optioned the right to purchase the assets from the option or at the predetermined price; a put option gives the optioned the right to sell the assets to the option or at the predetermined price. Both types of Option Agreements require the optioned to pay an option fee for the right to purchase or sell the assets. The option fee is typically non-refundable.
