There is an agreement made between 2 parties and it says that the term of the contract is from 1st Jan to 31st Dec 09. And at the same time, there is an annexure attached to it, that states after the end of 12 months, the contract will be renewed automatically. So do we have to renew the contract on 1st Jan 2010 or the silent terms itself extends the contract to the next year, please advice
