Tower Insurance Limited v Nicon Limited  NZCA 332 raised two fundamental issues relating to a Heads of Agreement (which may also be known as a terms sheet, memorandum of understanding (MOU), letter of intent (LOI), or similar).

The case shows that there are risks with entering into a Heads of Agreement. ..
