A hack that I think would work is:
  #! /bin/sh
  USER=user
  HOST=host.com
  RSYNC_OPTS='-av -e'
  RSYNC_OPTS2='ssh -2'
  RSYNC_BIN=/usr/bin/rsync
  ${RSYNC_BIN} ${RSYNC_OPTS} "${RSYNC_OPTS2}" ${USER}@${HOST}:~/test.txt .

PS I removed the "export" because you don't need them to be environment 
variables,
just shell variables.
