This assignment discusses the types of contractual terms, including express and implied terms, conditions, warranties, and exclusion clauses. The main difference between conditions and warranties is that a breach of condition allows for termination of the contract, while a breach of warranty only allows for damages. Implied terms are those that are not explicitly stated in the contract but are considered essential to its performance. In the present case, if it is considered that Office Pro X9's provision of sufficient lower back support was a term of the contract between Peter and the company, then it needs to be treated as a condition of the contract. An exclusion clause can reduce or exclude liability for breach of contract, but it must be properly added to the contract and not contravene the law. In this case, the exclusion clause cannot be relied upon because it is illegal, attempting to exclude obligations imposed on businesses by consumer legislation.
