250. (1) In any case where—

(a) a person is or is to be employed with a company under an agreement which cannot be terminated by the company by the giving of notice or can be so terminated only in specified circumstances, and

(b) more than 6 months before the expiration of the period for which he or she is or is to be so employed, the company enters into a further agreement (otherwise than in pursuance of a right conferred by or by virtue of the original agreement on the other party to it) under which he or she is to be employed with the company, or where he or she is a director of a holding company, within the group,

the definition of “relevant term” in section 249 shall apply as if to the period for which the person is to be employed under that further agreement there were added a further period equal to the unexpired period of the original agreement.

(2) Where subsection (1) has effect in relation to the definition of “relevant term” in section 249, subsection (6) of that section has effect as if there were substituted “the agreement and the original agreement referred to in section 250(1) shall each be deemed to contain a term entitling the company to terminate it at any time by the giving of reasonable notice” for “the agreement shall be deemed to contain a term entitling the company to terminate it at any time by the giving of reasonable notice”.

(3) For the purposes of this section “employment” and “group” have the same meaning as they have for the purposes of section 249.
