(b)even where the employee was excluded by or under this Order from any right conferred by this Order.
(2) For the purposes of Articles 190 and 197(1) a week of employment does not count in computing a period of employment if the employee—

(b)was not during that week an employed earner for the purposes of the [1992 c. 7.] Social Security Contributions and Benefits (Northern Ireland) Act 1992 in respect of whom a secondary Class 1 contribution was payable under that Act (whether or not the contribution was in fact paid).
