Amend HB 828 on third reading by adding the following 
appropriately numbered SECTION and renumbering subsequent SECTIONS 
of the bill accordingly:
	(f-1)  For a school district that, for the 2007 tax year or a 
subsequent tax year, adopts an exemption under Section 11.13(n), 
Tax Code, that was not in effect for the 2006 tax year or adopts an 
exemption under Section 11.13(n), Tax Code, at a greater percentage 
than the percentage in effect for the district for the 2006 tax 
year, the commissioner shall adjust the amount of the district's 
local revenue derived from maintenance and operations tax 
collections, as calculated for purposes of determining the amount 
of state revenue to which a school district is entitled under this 
section.  The commissioner shall calculate the adjusted local 
revenue as the amount of maintenance and operations taxes the 
district would have levied had the district not adopted, as 
applicable, an exemption under Section 11.13(n), Tax Code, for the 
2007 tax year or a subsequent tax year or increased the percentage 
of an exemption under Section 11.13(n), Tax Code, for the 2007 tax 
year or a subsequent tax year.  A determination by the commissioner 
under this subsection is final and may not be appealed.
