(1)If at any time during the period beginning with the relevant date and ending with the valuation date for the purposes of Schedule 6—
(a)there subsists between the nominee purchaser and a person other than a participating tenant any agreement (of whatever nature) providing for the disposal of a relevant interest, or
(b)if the nominee purchaser is a company, any person other than a participating tenant holds any share in that company by virtue of which a relevant interest may be acquired,
the existence of that agreement or shareholding shall be notified to the reversioner by the nominee purchaser as soon as possible after the agreement or shareholding is made or established or, if in existence on the relevant date, as soon as possible after that date.
(2)If—
(a)the nominee purchaser is required to give any notification under subsection (1) but fails to do so before the price payable to the reversioner or any other relevant landlord in respect of the acquisition of any interest of his by the nominee purchaser is determined for the purposes of Schedule 6, and
(b)it may reasonably be assumed that, had the nominee purchaser given the notification, it would have resulted in the price so determined being increased by an amount referable to the existence of any agreement or shareholding falling within subsection (1)(a) or (b),
the nominee purchaser and the participating tenants shall be jointly and severally liable to pay the amount to the reversioner or (as the case may be) the other relevant landlord.
(3)In subsection (1) “relevant interest” means any interest in, or in any part of, the specified premises or any property specified in the initial notice under section 13(3)(a)(ii).
(4)Paragraph (a) of subsection (1) does not, however, apply to an agreement if the only disposal of such an interest for which it provides is one consisting in the creation of an interest by way of security for a loan.
