In conclusion, terms must be agreed between the parties before the contract is signed or executed. Even expressed wording in contract terms stating that the standard terms will prevail over others may not be effective where it can be shown that no agreement was reached, whether expressly or by way of conduct.
The second important element is to clearly state the intended parties outcome from the disclosure. In the example above the intended outcome could be "The information is being disclosed to assess whether XYZ transportation company will pilot the software for use within its fleet". Again it is then clear what the outcome and the nature of the relationship will be. The example above is broad enough to allow some flexibility in discussion in the letter of intent e.g. that perhaps the pilot programme is limited to one territory as negotiations progress, but it must be narrow enough that the outcome is reasonably well known e.g. it is not expected that XYZ transportation become a shareholder in the software company.
