look at the openssl documentation (since exim uses openssl for all
tls/ssl processing, you should reflexively include a trip to the
opessl documentation for all these sorts of questions.)

http://www.openssl.org/docs/HOWTO/certificates.txt

is an incomplete howto on certificates. there is other documentation
scattered about opessl, including the openssl man page and various
related man pages such as ca and x509

you have a bit of reading to do; but one hint: PEM is a format for
certs, there are more than one. man x509 will probably help a bit.
