Listing restriction prevents venture capital fund units from immediate exchange listing under amended regulatory provisions. The amendment redefines associate company to focus on equity shareholdings by fund principals and substitutes 'shares' for broader securities references; it inserts a negation in regulation 4(d) and omits a proviso in regulation 12(d)(i). Regulation 13 is replaced to prohibit listing of venture capital fund units until the end of a specified post-issuance period. References to 'securities or' are removed from regulations 14, 15 and 17 to narrow the scope of instruments and clarify subscription and entitlement disclosures.
