In complex transactions, it is customary to prepare letters of intent or term sheets. They are not usually legally binding as the aim of the letters of intent or term sheets is to provide for the main terms and conditions of the prospective transaction, which remain subject to further negotiations between the parties. Provisions which are usually expressed as legally binding in the letter of intent include confidentiality, exclusivity and break-up fees.
Confidentiality or non-disclosure agreements are usually drafted as separately negotiated agreements (usually entered into by the parties before starting discussions on the transaction). Exclusivity and, if applicable, break fees are usually included in the term sheet if such agreement is binding, i.e., exclusivity will rarely be granted by the seller before a binding agreement is reached on the main terms and conditions of the transaction (in particular, within a bid process).
The Civil Code provides for an express obligation on parties negotiating a transaction, including a sale of shares, assets or business, to negotiate in good faith. This duty applies both in pre-contractual negotiations and during performance of the contract. The duty includes the obligation to inform the buyer of relevant important facts that the buyer could not discover on its own. Also, where negotiations are at an advanced stage giving rise to a reasonable expectation that the transaction will proceed, the unilateral termination of the negotiations by a party may give rise to damages if such termination is characterized as unfair/wrongful.
