PROVIDED that before fixing or varying any such percentage the Central Government shall give by like notification not less than two months' notice of its intention so to do and shall in such notification specify the percentage which it proposes to fix or, as the case may be, the extent to which the percentage already fixed is to be varied :

PROVIDED FURTHER that the employer's special contribution in the case of factories or establishments situate in any area in which the provisions of both Chapters IV and V are in force shall be fixed at a rate higher than that in the case of factories or establishments situate in any area in which the provisions of the said Chapters are not in force.

(4) The employer's special contribution shall fall due as soon as the liability of the employer to pay wages accrues, but may be paid to the Corporation at such intervals, within such time and in such manner as the Central Government may, by notification in the Official Gazette, specify, and any such notification may provide for the grant of a rebate for prompt payment of such contribution.
