Item 1.01 Entry into a Material Definitive Agreement

On November 9, 2007, ATS Corporation, a Delaware corporation (“ATS”), with Bank of America, N.A., as lenders’ agent and their other lenders and the guarantors listed on the signature page thereto, modified their existing credit agreement by entering into a second amendment to the Credit Agreement, Limited Consent and Agreement to Increase Commitments (the “Second Amendment”). The following primary changes were made pursuant to this second amendment: (i) allow for certain seller indebtedness in connection with Permitted Acquisitions (as defined in the Credit Agreement); (ii) increase the aggregate commitments from $25.0 million to $50.0 million; and (iii) the agent and lenders consented to the Borrowers’ acquisition of Number Six Software, Inc., a Delaware corporation (“NSS”).

Item 2.01 Completion of Acquisition or Disposition of Assets

On November 9, 2007, ATS completed its acquisition of NSS, pursuant to an Agreement and Plan of Merger and Reorganization, dated October 12, 2007, by and among ATS, NSS, ATS NSS Acquisition, Inc. and certain NSS stockholders (the “Merger Agreement”). The aggregate consideration of approximately $36.0 million includes $3.0 million in the form of ATS common stock valued at the average price over the 15-day period before the closing of the transaction, and promissory notes and deferred payments totaling approximately $6.0 million. The cash component of the purchase price is offset in part by negotiated terms expected to benefit ATS and reduce the net cash outlay associated with the transaction.
