On March 31, 2010, Technology Research Corporation (the “Company”) acquired 100% of the common stock of Patco Electronics, Inc., (“Patco”). The acquisition was effective March 31, 2010 and the results of Patco have not been included in the Company’s results of operations for the year ended March 31, 2010. The following unaudited pro forma condensed combined financial statements have been prepared to give effect to the completed acquisition, which was accounted for using the purchase method of accounting.

The unaudited pro form condensed combined statements of income for the two years ended March 31, 2010 are presented herein. The Company’s consolidated balance sheet filed in the Company’s Annual Report on Form 10-K reflects the acquisition of Patco. The unaudited pro forma condensed combined statement of income for the two years ended March 31, 2010 combines the historical results of the Company and Patco, and gives effect to the acquisition as if it had occurred on April 1, 2009 and 2008, respectively.

The unaudited pro forma condensed combined financial statements presented are based on the assumptions and adjustments described in the accompanying notes. Unaudited pro forma results of operations, assuming the acquisition was consummated at the beginning of fiscal 2009 and 2010, are presented for illustrative purposes. The pro formas represent the historical results of the Company combined with those of Patco for the periods presented, adjusted for specific factually supportable items such as amortization of intangible assets. The pro forma results of operations do not include the costs of integration or any nonrecurring costs and are not necessarily indicative of either future results of operations or results that would have been achieved if the acquisition had been consummated at the beginning of the periods presented in the accompanying financial statements. The unaudited pro forma condensed combined financial statements, and accompanying notes, are based upon the respective historical consolidated and combined financial statements of the Company and Patco, and should be read in conjunction with the historical financial statements and related notes of the Company contained in the Company’s Annual Report on Form 10-K for the year ended March 31, 2010, as well as the historical financial statements and related notes of Patco, which were attached as Exhibit 99.2 to the Company’s current report on Form 8-K filed on April 12, 2010.

2. Purchase Price Allocation

The preliminary allocation of the purchase price is based upon estimates of the assets and liabilities acquired in accordance with the relevant accounting guidance. The preliminary allocations may be reviewed when the Company completes its valuations. The acquisition of Patco is based on management’s consideration of past and expected future performance as well as the potential strategic fit with the long-term goals of the Company. The expected long-term growth, market position and expected synergies to be generated by Patco are the primary factors that gave rise to an acquisition price which resulted in the recognition of goodwill.

The following is a summary of the purchase price:

(in thousands)
Cash	$	5,000
Common Stock – 674,950 shares		2,426
Present value of contingent consideration		738
Purchase Price	$	8,164

The preliminary allocation of the aggregate purchase price of this acquisition is as follows:

(in thousands)
Goodwill	$	5,465
Identifiable intangible assets		3,584
Net assets acquired		(885	)
Purchase Price	$	8,164

3. Pro Forma Adjustments

a. To reflect amortization of the acquired intangible assets.

b. To adjust for acquisition related transaction costs.

c. To reflect the estimated decrease in interest income earned on the cash paid for the acquisition as if the cash was not available for investment during the period.

d. To adjust income tax expense on adjusting entries.

e. To adjust the weighted average share calculation for shares issued as part of the acquisition.
