Error While Executing Sqlplus from shell

Question

I am trying to execute the below shell script with out back ticks(`${ORACLE_HOME}/bin/sqlplus) while calling sqlplus in the below code. When i do that all the next lines after that are changing to red color in vi and when i execute the script i am getting an error as "syntax error: unexpected end of file". may i know i please know what could be the issue? i suspect it could be because of EOF, when i have the backticks on it is executing fine.
#!/bin/bash
logit "Updating the Validation Status Field in ${DBSTGUSER}.FEED_PROCESS_LOG Table as RUNNING With Matching Parameters"
        logit "UNINUM :: ${UNINUM} PROVIDER :: ${PROVIDER} EXTRACT_DT :: ${EXTRACT_DT} VER_NUM :: ${VER_NUM}"
        `${ORACLE_HOME}/bin/sqlplus ${DBSTGUSER}/${DBSTGPASS}@${DBSRC} <<EOF > ${UPD_FEED_PROC_LOG}
        spool ${UPD_SQL1}
        UPDATE ${DBSTGUSER}.FEED_PROCESS_LOG SET VALIDATION_STATUS='RUNNING'
        WHERE UNINUM='${UNINUM}' and PROVIDER='${PROVIDER}' and EXTRACT_DT='${EXTRACT_DT}'
        and VER_NUM=${VER_NUM} and ACT_END_DT IS NULL  AND (VALIDATION_STATUS IS NULL OR VALIDATION_STATUS='RUNNING');
        spool off;
        COMMIT;
        EXIT;
        EOF`
        if grep -q "ERROR" ${UPD_FEED_PROC_LOG}
        then
                logit "Error While Updating the ${DBSTGUSER}.FEED_PROCESS_LOG Table"
                logit "Please Check ${UPD_FEED_PROC_LOG} Log File For Detailed Information"
                exit 3
        else
                logit "Updation Of ${DBSTGUSER}.FEED_PROCESS_LOG Table Completed Successfully"
                logit "Please Check ${UPD_FEED_PROC_LOG} Log File For Detailed Information"
        fi

I know EOF stands for End of file and i am piping the data into the program (sqlplus).You could just as well use "FUBAR" in place of EOF; which just happens to be some arbitrary string.
piping ("|") is NOT involved , as in env | sort
you don't know, what you don't know.
