Schedule of Purchase Price Allocation

The table below sets forth the preliminary fair value assigned to the assets and liabilities acquired in the Pericom acquisition.  This preliminary purchase price allocation has been used to prepare pro forma adjustments in the pro forma condensed combined balance sheet and statements of earnings. U.S. GAAP permits companies to complete the final determination of the fair values of assets and liabilities up to one year from the acquisition date. The size and breadth of the Pericom acquisition will necessitate the use of this one year measurement period to adequately analyze and assess a number of the factors used in establishing the asset and liability fair values as of the acquisition date including (i) changes in fair values of fixed assets and inventories, (ii) changes in allocations of intangible assets such as trademarks and in process research and development and developed technology, as well as goodwill, and (iii) other changes to assets and liabilities. The final allocation may also result in changes to amortization periods assigned to the assets. Any potential adjustments made could be material in relation to the preliminary values. A final determination of the allocation of the purchase price to the assets acquired and liabilities assumed has not been completed and the following table is considered preliminary.
