Georgia Gulf Confirms Second Quarter Guidance of $.20 to $.25 EPS

    ATLANTA, June 19 /PRNewswire-FirstCall/ -- Georgia Gulf Corporation
(NYSE: GGC) confirmed today that it continues to expect second quarter net
income in the range of $.20 to $.25 per diluted share. The expected results
compare favorably to the first quarter net loss of $.05 per diluted share and
the second quarter 2002 net income of $.12 per diluted share, which included an
after tax benefit of a lawsuit recovery of approximately $1.1 million or $.03
per diluted share.

    Georgia Gulf expects improvement in earnings in spite of continued high
natural gas costs. The company expects slightly lower natural gas costs compared
to the previous quarter, but significantly higher natural gas costs compared to
the second quarter of 2002.

    Operating income is expected to improve compared to both the first quarter
and the second quarter last year. Sequentially, higher sales prices are expected
to more than offset higher raw materials costs and lower sales volumes. Compared
to the second quarter 2002, higher sales prices, primarily in vinyl resins, are
expected to outpace higher raw materials and natural gas costs.
