Currently under LOI on a business but the LOI included a valuation range. Seller is expecting a "formal offer" and we've already completed a fair amount of the due-diligence under the current LOI. We're not ready to produce definitive documentation but I'd prefer that the next agreement executed be something with some teeth. Does anyone have an agreement that would function nicely as something in-between an LOI and Definitive Agreements? Again, something with teeth and that's less easy to walk away from (for both parties) than a typical LOI.
