A contract drafter should resist attempting to insert more emphatic wording than is necessary to achieve the purpose of an obligation or a provision. If words are clear and precise, there is no need to underline that they mean what they say. A few words seem to be particularly common. For example:
No Party shall subject its interests in the Shares in any manner whatsoever to a right of pledge, a right of usufruct or other encumbrance of any kind.
Upon settlement of the IP Claim, Peterson shall have no right of action whatsoever against Johnson.
Purchaser may in its sole discretion waive any of the Conditions under paragraphs (a), (c) and (d) at any time.
Obviously, a compromise in discussions between the parties may well result in a contract provision emphasising that a certain behaviour is prohibited. Do not avoid such psychological strategies.
