Commercial Contracts [PDF ebook] 
A Practical Guide to Deals, Contracts, Agreements and Promises

This book aims to explain the principles of contract law for the businessman, and to put those principles into their commercial context. Anyone involved in commercial transactions needs at least a basic understanding of the principles of contract law – the legal framework for all commercial activity. A lack of such a basic understanding at best results in a business which is less competitive and ultimately less profitable than it should be, and at worst can have expensive and sometimes disastrous commercial consequences.
