Hi Jinyan,
HuExExonProbesetLocationHg18  <http://www.bioconductor.org/help/bioc-views/release/data/annotation/html/HuExExonProbesetLocationHg18.html>
and
HuExExonProbesetLocationHg19  <http://www.bioconductor.org/help/bioc-views/release/data/annotation/html/HuExExonProbesetLocationHg19.html>
Contain exon-level annotation extracted from Netaffx:
The package contain a data frame with the following columns:
EPROBESETID exon-level probeset id
CHR chromosome
STRAND chromosome strand
START start position of the Probe Selection Region on chromosome
END end position of the Probe Selection Region on chromosome
GPROBESETID Gene-level probeset id
ANNLEVEL annotation level

On the basis of chromosome location it is relatively easy to associate gene level information using a package as ChIPpeakAnno
Cheers
Raffaele
