(ss-1/sec. 173) notice and agenda of bod meeting

As per SS-1 Notice and Agenda are required to be sent 7days before the Board Meeting applicable from 1st July, 2015. But, if board meeting is called on shorter notice , is it that we can give agenda also with notice at shorter time . what if prov. not complied ? as act shows the penalty of Rs. 25,000/- only in case of not serving notice as per prov., or is it applicable for agenda also???
