Item 1.01. Entry into a Material Definitive Agreement

On September 12, 2007, HAPC, INC., a Delaware corporation (“HAPC”) entered into a non-binding Memorandum of Intent (the “MOI”) with I-Flow Corporation (“I-Flow”), InfuSystem, Inc. (“InfuSystem”) and Iceland Acquisition Subsidiary, Inc. with respect to the Stock Purchase Agreement, dated as of September 29, 2006, as amended (the “Stock Purchase Agreement”), by and among the foregoing parties.

The MOI contemplates a further amendment to the Stock Purchase Agreement which would reduce the original purchase payable by HAPC to I-Flow for all of the issued and outstanding capital stock of InfuSystem from $140,000,000 to $100,000,000 with contingent consideration to be paid several years from the closing date of the acquisition, provided that certain conditions related to the operations of InfuSystem’s business are met. The contingent consideration would be based upon the compound annual growth rate of HAPC’s consolidated revenues over the three year period ended December 31, 2010 and would be paid in 2011. The maximum potential amount of the contingent consideration is $12 million and would be payable to I-Flow if HAPC achieved a compound annual growth rate of 50% over the three year period.
