the case of married individuals who make a joint return for the taxable year of such sale or exchange, if either spouse is a qualifying senior, paragraphs (2) and (4) shall each be applied by substituting $1,000,000 for $500,000 each place it appears, and
in the case of a qualifying senior who is married and makes a separate return for the taxable year of such sale or exchange, paragraph (1) shall be applied by substituting 500,000 for $250,000..
