Item 2.01  Completion of Acquisition or Disposition of Assets

On February 15, 2012, we entered into a definitive agreement pursuant to which we acquired, through our XYZ Holdings, Inc. wholly-owned Georgia subsidiary (“Holdings”), all of the issued and outstanding limited liability company membership interests (the “Interests”) in OmniMetrix, LLC, a Georgia limited liability company (“OmniMetrix”).  OmniMetrix is in the business of designing, manufacturing, marketing and selling (i) wireless remote systems that monitor standby power generation, backup power generators, remote powered equipment, cellular towers, emergency towered communications and remote tower sites, (ii) wireless remote systems that monitor landfill gas, and (iii) cathodic protection products to monitor pipeline integrity.

Holdings purchased the Interests in OmniMetrix from its three individual holders (the “Sellers”) in consideration for an aggregate cash payment of $8,500,000, subject to certain adjustments as provided in the definitive agreement.  The purchase price proceeds will be used first to discharge approximately $2,769,000 of indebtedness in the aggregate owed by OmniMetrix to the Sellers and an affiliate (including salaries, rent, royalties and notes payable), with the balance, net of transaction expenses, paid to the Sellers pro rata according to their respective percentage ownership of the Interests. A portion of the purchase price was placed in escrow to secure the Sellers’ indemnification obligations under the agreement, with the balance to be released 18 months after the date of closing.  We have guaranteed Holdings’ performance of its indemnity obligations to the Sellers under the agreement.
