EXIT or RETURN in Stored Procedures

Question

Anyone,
Should I use EXIT/RETURN/GOTO when in a stored procedure and I am trying to deal with EXCEPTION handling but need to exit out of stored proc handing back a value in an OUT variable to the calling procedure?
I have been working with all three and I still seem to have a memory leak that causes a
"ORA-03113: end-of-file on communication channel"
Error after running the same procedures several times. I think this is related to the way I am exiting the procedure and the fact that I am in nested CURSORS.
Any help would be greatly appreciated.
Thanks,
Miller

The following example should help.
SQL> VARIABLE MYVAR VARCHAR2
SQL> DECLARE
  2  PROCEDURE TEST(p1_out OUT VARCHAR2) AS
  3  BEGIN
  4  SELECT 'X' INTO p1_out FROM
  5  DUAL
  6  UNION
  7  SELECT 'X' FROM DUAL;
  8  EXCEPTION
  9  WHEN TOO_MANY_ROWS THEN
10   p1_out := 'Y';
11  END;
12  BEGIN
13  TEST(:myvar);
14  END;
15  /
PL/SQL procedure successfully completed.
SQL> PRINT MYVAR
MYVAR
X
