6(1)The first of the basic conditions shall be subject to an exception for shares held by another private company which is itself an exempt private company :
Provided that this exception shall not apply, if, taking all the following companies together, that is to say—
(a)the company whose exemption is in question (hereafter in this Schedule referred to as “the relevant company ”) ;
(b)any company holding shares to which this exception has to be applied in determining the relevant company's right to be treated as an exempt private company ; and
(c)any further company taken into account for the purposes of this proviso in determining the right to be so treated of any company holding any such shares as aforesaid ;
the total number of persons holding shares in those companies is more than fifty, joint shareholders being treated as a single person and the companies themselves and (subject to sub-paragraph (4) of this paragraph) their employees and former employees being disregarded.
(2)Where the relevant company and another company hold shares in each other, the other company shall be treated for the purposes of the foregoing sub-paragraph as an exempt private company if—
(a)in determining its right to be so treated the exception in that sub-paragraph would apply to the shares in it held by the relevant company, on the assumption that the relevant company was an exempt private company ; and
(b)in all other respects the other company is entitled to be so treated ;
and where another company's right to be so treated depends on the application to any shares in it of that sub-paragraph, and the application thereof to those shares depends indirectly on the relevant company's right to be so treated, this sub-paragraph shall apply as if those shares were held by the relevant company.
(3)Where by virtue of this paragraph any shares are excepted from the first of the basic conditions, the second of those conditions shall be subject to an exception for any interest in those shares which any person has by virtue of debentures of the company holding those shares, or as trustee of a deed for securing an issue of debentures of that company.
(4)In the proviso to sub-paragraph (1) of this paragraph, the direction that employees and former employees of the companies shall be disregarded in computing the number of shareholders shall not apply to a person holding shares in a company of which he is not for the time being an employee unless, having been formerly in the employment of that company, he held, while in that employment, and has continued after the determination of that employment to hold, shares in that company.
