NEW YORK, JANUARY 18, 2005 - Macquarie Infrastructure Company (NYSE: MIC) today
advised that a performance fee of $12.088 million is payable to its Manager,
Macquarie Infrastructure Management (USA) Inc., for the quarterly period ended
December 31, 2004.

Under the terms of its management services agreement, the Manager of MIC is
eligible to earn a performance fee each quarter if the MIC Accumulation Index(1)
outperforms a benchmark represented by a weighted average of the MSCI U.S.
IMI/Utilities Index and the MSCI Europe Utilities Index(2). The performance fee
payable is 20% of the outperformance by the MIC Accumulation Index over the
Benchmark for the period.

In the period since MIC's initial public offering on December 16, 2004 to
December 31, 2004, the MIC Accumulation Index has outperformed the benchmark by
9.08%, or $60.442 million. The MIC Accumulation Index increased by 12.34% over
the period compared to a 3.26% increase for the benchmark. This outperformance
results in a performance fee payable of $12.088 million.

The increase in shareholder value both in absolute and relative terms follows
the successful completion of the Company's initial public offering in December
2004. The Manager has elected to apply the performance fee to a subscription for
MIC trust stock at the market price of the trust stock subsequent to MIC's
earnings release for the quarter ended December 31, 2004.

MIC reaffirms its stated dividend policy to declare and pay an initial quarterly
distribution for the quarter ended March 31, 2005 of $0.50 per share. MIC also
intends to pay an initial distribution to shareholders, pro-rated for the period
from the completion of the Company's initial public offering to December 31,
2004, at the same rate as such initial quarterly distribution that will be paid
at the same time as the initial quarterly distribution.

The Company also today announced the completion of the acquisition of General
Aviation Holdings by its airport services business, Atlantic. The total funds
required for the acquisition of $53.4 million (which includes reserves and
transaction costs) were sourced from an expansion of Atlantic's current credit
