USA Mobility said to partially fund the $150 million in cash consideration payable to Metrocall stockholders in the merger, Metrocall Inc. and Arch Wireless Operating Inc.-two subsidiaries of the new paging company-borrowed $140 million under a senior secured credit facility from a syndicate of lenders led by UBS Loan Finance L.L.C. and UBS Securities L.L.C. USA Mobility said it and substantially all of its subsidiaries have guaranteed the facility. Available cash on hand at Metrocall and Arch was used to pay the balance of the cash consideration to Metrocall stockholders as well as fees, costs and expenses associated with the transaction and will be used for working capital purposes of the combined company. The Justice Department said the merger did not pose any competitive dangers, given the wide availability of alternative wireless services such as mobile telephony.
