(a) Holdco will accept that transfer; and

(b) Holdco will provide to each Scheme Shareholder the Scheme Consideration in accordance with the Scheme by:

Fractional entitlements

4.4 Where a Scheme Shareholder would otherwise be entitled under the Scheme to a fraction of a Holdco Share or a number of Holdco CDIs that do not equate to a whole number of Holdco Shares as part of the Scheme Consideration, the fractional entitlement will be rounded up to the nearest whole number of Holdco Shares.

(b) as soon as is reasonably practicable despatches, or causes to be despatched, to each Scheme Shareholder who is to receive Holdco CDIs under the Scheme, a holding statement or confirmation advice in the name of that Scheme Shareholder representing the number of Holdco CDIs issued to that Scheme Shareholder.

4.7 The obligation to issue Holdco Shares under clause 4.3 will be satisfied by Holdco, on the Implementation Date, procuring the entry into its register of stockholders the name of each person who is to receive Holdco Shares.

Sale Facility

4.8 Where a Scheme Shareholder is an Ineligible Foreign Shareholder, the number of Holdco Shares to which that Scheme Shareholder would otherwise have been entitled to under the Scheme (after any necessary rounding) will be issued to the Sale Agent (in the form of Holdco CDIs) and sold under the Sale Facility.

4.9 ABR will procure that, after the Implementation Date, the Sale Agent:

(a) as soon as is reasonably practicable and, in any event, within 1 month after the Implementation Date, sells all Holdco CDIs issued to it under clause 4.8 in such manner, at such price and on such other terms as the Sale Agent determines in good faith and at the risk of the Ineligible Foreign Shareholders; and

(b) as soon as is reasonably practicable and, in any event, within 10 Business Days after the settlement of the sale of the last of the Holdco CDIs, remits the gross proceeds of the sale (free of any brokerage costs) to the Ineligible Foreign Shareholders in the amount to which they are entitled (on an averaged basis so that each Ineligible Foreign Shareholder receives the same price per Sale Security, subject to rounding to the nearest whole cent).

4.10 The remittance to each Ineligible Foreign Shareholder of the sale proceeds pursuant to clause 4.9(b) is in full and final satisfaction of that Ineligible Foreign Shareholder’s right and entitlement to the Scheme Consideration referable to it.

Options

4.13 ABR and Holdco will use all reasonable endeavours to enter into binding agreements with each Option Holder to cancel the Options held by such Option Holder in consideration for the grant of equivalent rights (as near as reasonably practicable) to acquire Holdco Shares instead of ABR Shares (Holdco Options).
