Disclaimer clause usually has no specific wording and depends upon the terms of the contract. The use is to transfer responsibility from yourself, maybe onto an other party.
For example, if I was a dealer selling some software product, then I may include a disclaimer clause stating that I am only an intermediary in the supply chain and not the original writer of the software, and hence shall not be responsible for the performance of the software.
The importance of this clause must be evident from the above discussion. In absence of such a clause, you may be held responsible for something which is beyond your control and for which you would not like to be held responsible.
