("RES") and the tape storage division of Raytheon Company pursuant to a Stock Purchase Agreement with RES, dated July 21, 1991 (the "Stock Purchase Agreement"). Pursuant to the Stock Purchase Agreement, the Company made a cash payment of $24,766,000 to RES and assumed approximately $2,000,000 in mortgage indebtedness in exchange for one hundred percent of the outstanding stock of EMASS (the "Acquisition"). The Acquisition was financed from existing cash of the Company and a loan on customary terms from Seafirst Bank in the amount of $20,000,000. The Company expects to incur certain restructuring costs as well as a significant one-time expense for purchased research and development in connection with the Acquisition. Restructuring costs will generally be capitalized as liabilities related to the cost of the Acquisition while the purchased research and development charge will be reflected as a non-recurring expense in the Company's financial statements for the quarter and fiscal year ending October 31, 1998. EMASS is headquartered in Englewood, Colorado, with European operations based in Bohmenkirch and Frankfurt, Germany. Founded as a mass storage provider with emphasis on satellite download data and scientific archive solutions, EMASS has evolved into a major provider of large-scale data libraries and open systems storage software. Products range from the AML/S mixed media library, which scales to 50 terabytes, to the AML/2 data library, which scales to 50,000 cartridges and petabytes of data.
