“Macquarie Group” refers to the Macquarie Group of companies, which comprises Macquarie Bank Limited and its worldwide subsidiaries and affiliates.

On June 18, 2007, Macquarie Infrastructure Company LLC (“MIC” or the “Company”) filed a current report on Form 8-K (the “Original Form 8-K”) with respect to an agreement to amend the stock purchase agreement previously entered into with Allied Capital Corporation, Directional Aviation Group, LLC, David Moore and Kenneth Ricci for the acquisition of Mercury Air Centers, Inc. (“Mercury”). This current report on Form 8-K/A (this “Report”) amends and restates the Original Form 8-K in its entirety.

Section 1 — Registrant’s Business and Operations

Item 1.01 Entry into a Material Definitive Agreement.

On June 12, 2007, Macquarie Infrastructure Company LLC (together with its subsidiaries, “MIC”), through a wholly-owned subsidiary, entered into an agreement to amend the stock purchase agreement previously entered into with Allied Capital Corporation, Directional Aviation Group, LLC, David Moore and Kenneth Ricci for the acquisition of Mercury Air Centers, Inc. (“Mercury”). This amendment reflects Mercury, through a wholly owned subsidiary, entering into an agreement to purchase 100% of the membership interests in SJJC Aviation Services, LLC (“SJJC”) from San Jose Jet Center Inc. (“Jet Center Inc”) and ACM Aviation Inc. (“ACM Inc”). The closing of the acquisition of SJJC by Mercury is conditioned on either MIC’s closing of its acquisition of Mercury or the termination of MIC’s acquisition of Mercury. In the event of a termination or failure to close the acquisition of Mercury by November 1, 2007, Mercury is obligated to assign to a wholly-owned subsidiary of MIC all of its rights and obligations under the SJJC agreement. As a result, MIC has effectively entered into an agreement to acquire SJJC.

SJJC, through its wholly owned subsidiaries, operates two fixed based operations (“FBOs”) at Mineta San Jose International Airport, CA. Together with the Mercury acquisition, MIC will acquire a total of 26 FBOs.

The total purchase price for the Mercury acquisition, including the acquisition of SJJC, has increased to $615.0 million, subject to working capital adjustments and including $36.9 million of transaction costs, integration costs and reserve funding. To partially finance the acquisition, a wholly-owned subsidiary of MIC entered into commitment letters with each of The Governor and Company of the Bank of Ireland and Bayerische Landesbank, New York Branch, respectively, providing for an aggregate of $272.0 million of bridge loan borrowings and $17.5 million in capital expenditure facilities. The facilities will be individually secured by all of the assets of Mercury and SJJC. Further, the SJJC facility is guaranteed by Macquarie FBO Holdings LLC, a wholly owned subsidiary of MIC. The key terms of the new bridge debt facilities are outlined in the table below:

Facility 1

Term		Detail and Comment
Borrower		Mercury
Facilities		§    $192.0 million bridge term loan facility
		§    $12.5 million capital expenditure revolving facility
Interest rate		LIBOR plus 1.70%
Maturity		2 years from closing date
Guarantor		None

Facility 2

Term		Detail and Comment
Borrower		SJJC
Facilities		§  $80.0 million bridge term loan facility
		§  $5.0 million capital expenditure revolving facility
Interest rate		LIBOR plus 1.70%
Maturity		2 years from closing date
Guarantor		Macquarie FBO Holdings LLC

MIC has entered into the following interest rate swaps to fix 100% of its interest exposure under the Mercury and SJJC bridge term loan facilities:

Amount		Start date		End date		Fixed rate
$144 million		Sep 28, 2007		Sep 28, 2009		4.9925%
$48 million		Sep 28, 2007		Sep 28, 2009		5.0175%
$80 million		Sep 28, 2007		Sep 30, 2009		5.4420%

MIC has entered into commitment letter with Macquarie Bank Limited providing for an increase in its revolving acquisition facility of $30 million to pay the remainder of the aggregate purchase price for both the Mercury and SJJC acquisitions and associated costs. The material terms of the revolving acquisition facility will remain the same except as follows:

Interest rate margin:		§  For the first six months following close, 2% for LIBOR loans or 1% for base rate loans.
		§  Thereafter, 2.5% and 1.25% until the SJJC tranche is repaid.
		§  1.25% and 0.25% following repayment of the SJJC tranche.
Debt Covenant		The Borrower and the Guarantor shall agree not to incur additional debt until SJJC tranche has been repaid or terminated.
Maximum Leverage Ratio		Increasing to a maximum of 6.8x for the quarters ending June 30, 2007 through maturity and reverting to 5.6x when SJJC tranche has been repaid or terminated.

The full terms of all the commitment letters referred to above are incorporated by reference to the commitment letters filed with this the Original Form 8-K.

MIC intends to conduct an equity offering, subject to market conditions and management’s discretion, which may be used to partially fund the Mercury and SJJC acquisitions in lieu of a drawdown of its revolving acquisition facility.

The purchase agreements contain various provisions customary for transactions of this size and type, including representations, warranties and covenants with respect to the business that are subject to customary limitations. The amended agreement provides for escrows for a total amount of $22.0 million to cover indemnities. The SJJC purchase agreement also provides for a break fee payable by MIC of $10.0 million if MIC does not close the transaction following MIC’s public filing of financial information of SJJC, as well as a termination of the no material adverse change condition to closing.

Completion of the acquisitions are subject to regulatory and other approvals, including approvals of the relevant airport authorities, the expiration or early termination of any waiting period under the Hart-Scott-Rodino Antitrust Act and other customary closing conditions.

Macquarie Securities (USA) Inc. (“MSUSA”) is acting as financial advisor to MIC on the Mercury and SJJC acquisitions and MIC expects to pay approximately $7.7 million in fees to MSUSA. MSUSA is a subsidiary of Macquarie Bank Limited, the parent company of MIC’s Manager. Macquarie Bank Limited has provided commitments for the increase in MIC’s revolving acquisition facility.
