Check out the handbook page on NFS:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-nfs.html
"In /etc/exports, each line represents the export information for one
file system to one host. A remote host can only be specified once per
file system, and may only have one default entry. For example, assume
that /usr is a single file system. The following /etc/exports would be
invalid:
# Invalid when /usr is one file system
/usr/src client
/usr/ports client
One file system, /usr, has two lines specifying exports to the same
host, client. The correct format for this situation is:
/usr/src /usr/ports client
The properties of one file system exported to a given host must all
occur on one line. Lines without a client specified are treated as a
single host. This limits how you can export file systems, but for most
people this is not an issue."
