MEDIA RELEASE

MACQUARIE INFRASTRUCTURE COMPANY TO ACQUIRE 50%                 [MACQUARIE LOGO]
OF US BULK LIQUID STORAGE TERMINAL COMPANY

NEW YORK, APRIL 17, 2006 - Macquarie Infrastructure Company (NYSE: MIC)
announced that it has entered into a stock subscription agreement under which it
will invest $250 million in exchange for new shares of common stock representing
a 50% indirect interest in International-Matex Tank Terminals ("IMTT").

The investment will be immediately yield-accretive to MIC upon closing and will
further diversify MIC's sources of cash available for distribution to
shareholders. Under the shareholders' agreement between MIC, IMTT and the other
shareholders of IMTT, MIC expects to receive fixed quarterly distributions from
IMTT of $7.0 million for quarters ended June 30, 2006 through December 31, 2007.

Founded in the 1940's, IMTT is one of the largest owner/operators of bulk liquid
storage terminals in the United States, based on capacity. The company also owns
interests in two facilities in Canada.

IMTT is a family-owned business and the current shareholders will retain a 50%
stake in the company. All members of IMTT's senior management team will continue
in their current roles.

Commenting on the transaction, Peter Stokes, Chief Executive Officer of MIC,
said "IMTT is a well established and highly regarded company in the bulk liquid
storage terminal industry. Its portfolio of terminal facilities generate strong,
predictably stable cash flows. A portion of the funds contributed to IMTT by MIC
will help IMTT strengthen and grow these cash flows through the expansion of
existing facilities and the development of new facilities that we believe will
support higher levels of distributable cash in the future."

"The existing owners, who remain as equal shareholders in the business alongside
MIC, provide operational expertise and continuity to IMTT. We believe MIC's
perspective as a long-term investor and the resources available through MIC will
complement IMTT's core strengths," Mr. Stokes added.


Stokes noted that the agreement to acquire 50% of IMTT provides MIC with
immediate critical mass in a new sector of infrastructure. The bulk liquid
storage terminalling industry meets all of MIC's investment criteria, including
providing an essential service that enjoys relatively inelastic demand and
operating with high barriers to entry.

ABOUT INTERNATIONAL MATEX TANK TERMINALS (IMTT)
IMTT owns and operates a high quality portfolio of bulk liquid storage terminal
facilities located across the US and Canada.

In the United States IMTT's operations include owning and operating 8 bulk
liquid storage terminals with a combined storage capacity of approximately 33
million barrels. IMTT stores and handles petroleum and liquid chemical products
on behalf of a diversified third party client base. IMTT assumes no commodity
price risk relative to the products it stores.

The majority of IMTT's revenues are derived from its two largest terminal
facilities, located in Bayonne, NJ and St. Rose, LA, serving New York harbor and
the lower Mississippi river, respectively. Both are key entry and distribution
points for bulk liquid products in the US.

Each of the two major facilities has attractive deepwater berthing capability,
access to pipelines and rail and road transportation networks. Both are situated
in areas of substantial demand for petroleum and chemical products and therefore
bulk liquid storage.

IMTT is currently undertaking the development of new capacity at St. Rose and a
new "greenfield" bulk liquid logistics facility in Geismar, LA. The Geismar
facility is being developed to serve the needs of the German company BASF at its
Geismar chemicals facility, primarily, although the facility may be used to
service other customers as well. This facility is expected to be operational by
the end of 2007.

IMTT also owns interests in and operates two facilities in Canada that provide
additional storage capacity of approximately 4 million barrels.

ACQUISITION FUNDING AND TIMING
MIC expects to finance the investment of $250 million, and associated
transaction costs of $7.0 million, with available cash and borrowings under the
revolving credit facility of Macquarie Infrastructure Company, Inc. (MIC Inc.).
MIC Inc. is a wholly-owned subsidiary of MIC and the holding company for its US
businesses. In conjunction with its investment in IMTT, and to be certain that
resources are available to complete another pending transaction (The Gas
Company), MIC, Inc. has entered into commitment letters with several of its
existing lenders under the facility to increase the amount available from $250
million to $300 million.

The investment in IMTT is expected to close in the second quarter of 2006
subject to satisfaction of typical conditions precedent for a transaction of
this size and type. Detailed financial data for IMTT will be filed with the SEC
following closing.

Macquarie Securities (USA) Inc. is acting as financial advisor to MIC in
relation to the transaction.
