On December 8, 2010, Sparton Technology, Inc., a New Mexico corporation (“Seller”) and wholly-owned subsidiary of Sparton Corporation, an Ohio corporation (“Sparton”), entered into an agreement for the purchase and sale of real property (the “Purchase Agreement”) with Coven Holdings LLC, a New Mexico limited liability company (“Buyer”), for Seller’s property located at 8500 Bluewater Road NW, Albuquerque, New Mexico (“Property”). The total purchase price for the Property is $4.5 million. Buyer paid $1 million earnest money to Fidelity National Title, to be held in escrow pursuant to the Purchase Agreement. The earnest money and accrued interest is fully refundable for the forty-five day period which Buyer has to review the Property (the “Inspection Period”). The balance of the purchase price is due at closing. The sale is currently expected to close by February month end.

Under the Purchase Agreement, the sale is subject to customary closing conditions, including a title commitment, a survey, an environmental site assessment and the physical inspection of the Property. Prior to the end of the Inspection Period, in the event that Buyer is dissatisfied with the title, survey, environmental site assessment or physical condition of the Property, Buyer has the right to either terminate the Purchase Agreement or give notice to Seller requesting that Seller cure the items disapproved by Buyer. If Buyer elects to terminate the Purchase Agreement, Buyer shall be entitled to return of the earnest money and accrued interest. If Buyer does not disapprove the Property, the earnest money shall become non-refundable, but will continue to be held by Fidelity National Title, and shall be credited against the purchase price at closing. Sparton can offer no assurances that the sale will close on the terms described herein, or at all.

The foregoing does not constitute a complete summary of the terms of the Purchase Agreement and reference is made to the complete form of the Purchase Agreement and to the press release that are attached as Exhibit 10.1 and Exhibit 99.1, respectively, to this report and are hereby incorporated by reference.
