Remuneration

If the Executive Director of a Company wishes to revise the T&C of his appointment; whereas  in the Annual Report it is written subject to T&C (such as medical reimbursement, leave travel allowance, gratuity etc) and shareholder's approval, how can he proceed? Do we need to hold an EGM or directly revise it in the AGM. Also the case says that the Remuneration Committee is authorised to revise salary by giving annual increment on (date)  onwards evvery year.
