(3) Sub-paragraph (1) does not apply to any agreement to refrain from instituting or continuing before an employment tribunal proceedings within section 18(1) of the Employment Tribunals Act 1996 (which specifies proceedings under these Regulations as being proceedings where conciliation is available(1)) if the conditions specified in paragraph 13 regulating compromise agreements are satisfied in relation to the agreement.
