"Side Letter to the Transaction Agreement"

A transaction agreement is a legal contract that lays out the terms and steps for a specific business deal—such as a merger, acquisition, asset sale, financing, or securities purchase. It defines what each party must do, what is being exchanged, conditions that must be met, and how disputes are handled. For investors it matters because this document determines the rights, timing, risks, and potential payments they can expect from the deal, much like a recipe and schedule that guides a complex group project.
