Item 2.01 Completion of Acquisition or Disposition of Assets

     On October 3, 2005, Tekelec, a California corporation (“Tekelec”), completed the acquisition (the “Acquisition”) of all of the shares of capital stock (the “Santera Shares”) of Santera Systems Inc. , a Delaware corporation (“Santera”), owned by Santera’s minority stockholders for an aggregate cash purchase price of $75,550,000 (the “Purchase Price”). Prior to the Acquisition, Santera had been a majority owned subsidiary of Tekelec. As a result of the Acquisition, Santera is a wholly owned subsidiary of Tekelec.

     The Acquisition was consummated pursuant to the terms of (i) an Agreement and Plan of Merger dated as of April 30, 2003, as amended on August 3, 2005, by and among the Company, Luke Acquisition Corp., Santera, certain stockholders of Santera, and Austin Ventures VI, L.P., as the representative of the minority stockholders of Santera (the “Representative”), (ii) an Escrow Agreement dated as of April 30, 2003, as amended on August 3, 2005, by and among the Company, Santera, the minority stockholders of Santera, the Representative and J.P. Morgan Trust Company, National Association, and (iii) a Stockholders’ Agreement of Santera Systems Inc. dated as of April 30, 2003 (the “Original Stockholders’ Agreement”), as amended on August 3, 2005, by and among the Company, Santera, the minority stockholders of Santera and the Representative (collectively and as amended, the “Amended Transaction Documents”).

     The final terms and conditions of the transaction, including the Purchase Price, were negotiated and determined by the parties based on arm’s-length negotiations between Tekelec and the Representative and a number of factors, including the purchase price formula for the Santera Shares as set forth in the Original Stockholders’ Agreement; a valuation of the Santera Shares as determined by Tekelec’s management following a review and analysis of Santera’s business, business prospects and financial condition; and indemnification claims that had been asserted by Tekelec against the minority stockholders of Santera. Prior to the August 3, 2005 amendment of the transaction documents, Tekelec had asserted various indemnification claims against the minority stockholders and had notified them of additional unasserted claims. The Representative, on behalf of the minority stockholders, had objected to the validity and amounts of the asserted claims, and the Representative and the minority stockholders had also notified Tekelec that the Representative and the minority stockholders had various unasserted claims against the Company and its affiliates. Upon the closing of the Acquisition, the parties’ indemnification obligations under the Amended Transaction Documents terminated.

     The source of funds used by Tekelec to acquire the Santera Shares was existing cash reserves of Tekelec.

     Santera is a provider of media gateways and softswitches that are a part of the next-generation Class 4, Class 5, wireless and wireline solutions that Tekelec provides to telecommunications operators.

     The foregoing description of the Acquisition is qualified in its entirety by reference to the Amended Transaction Documents which are incorporated by reference in this Current Report on Form 8-K.
