Key insights covered include:

• What to include in your LOI, from deal structure and earnouts to working capital and exclusivity

• Which terms are binding versus non-binding

• Common mistakes that derail deals before due diligence even begins

• Key differences between LOI practices in the UK, US, and Europe
