The EXIT WHEN syntax can exit a loop depending on a condition. It should be preferred to the more verbose and error-prone IF ...
THEN EXIT; END IF; syntax.
Noncompliant code example
SET SERVEROUTPUT ON
DECLARE
  i PLS_INTEGER;
BEGIN
  i := 0;
  LOOP
    IF i > 10 THEN -- Noncompliant
       EXIT;
    END IF;
    DBMS_OUTPUT.PUT_LINE('i = ' || i);
    i := i + 1;
  END LOOP;
END;

Compliant solution
SET SERVEROUTPUT ON
DECLARE
  i PLS_INTEGER;
BEGIN
  i := 0;
  LOOP
    EXIT WHEN i > 10;
    DBMS_OUTPUT.PUT_LINE('i = ' || i);
    i := i + 1;
  END LOOP;
END;
