Westlink M7 Call Option Exercised

19 December 2005

Macquarie Infrastructure Group (MIG) advises that it has exercised its fixed price option to acquire an additional 5% equity interest in Westlink M7 for A$47.4 million. This interest was held by Abigroup Limited (2.5%) and Leighton Holdings Limited (2.5%).  This price represents a discount of 3.3% to par value.

Abigroup Limited and Leighton Holdings Limited continue to hold a total interest of 10% in Westlink M7, over which MIG and Transurban Group have pre-emptive rights.

The option to acquire the Abigroup Limited and Leighton Holdings Limited interests was foreshadowed by MIG at the time of Westlink M7 financial close.

MIG now holds a 45% direct stake and a 1.25% indirect stake (through MIG’s investment in Transurban) in Westlink M7.
