Alliance Imaging will use the net proceeds of the offering, together with proceeds from new term loans pursuant to a proposed refinancing of the Tranche C term loans under its credit agreement, to fund (i) the purchase by Alliance Imaging of all of its outstanding 10 3/8% Senior Subordinated Notes due 2011 pursuant to a tender offer and consent solicitation commenced on November 30, 2004, (ii) the consummation of the credit agreement refinancing, and (iii) the payment of the fees and expenses related to the issuance of the new notes, the incurrence of the new term loans, the credit agreement refinancing, and the tender offer and consent solicitation. Alliance Imaging anticipates that it will seek to issue up to $150.0 million in aggregate principal amount of senior subordinated notes and raise approximately $410.0 million of new term loans.
