Section 1 – Registrant’s Business and Operations

Item 1.01. – Entry into a Material Definitive Agreement.

On June 11, 2008, Invitrogen Corporation, a Delaware corporation, or the Company, Atom Acquisition, LLC, a Delaware limited liability company and a direct wholly owned subsidiary of the Company, or Atom Acquisition, and Applera Corporation, a Delaware corporation, or Applera, entered into an agreement and plan of merger, or the Merger Agreement. Pursuant to the Merger Agreement, Applera will be merged with and into Atom Acquisition and Atom Acquisition will be the surviving corporation and the Company’s wholly owned subsidiary.

At the effective time of the merger (the “Effective Time”), each issued and outstanding share of Applera’s common stock, par value $.01 per share, automatically will be converted into the right to receive $17.10 in cash and 0.4543 of a share of the Company’s common stock, par value $.01 per share, or $38 per share of Applera common stock. Applera’s stockholders may elect to receive either all cash or only shares of the Company for each share of Applera’s common stock, subject to proration if either the cash or stock election is oversubscribed. If the arithmetic average of the weighted average price, as defined, of the Company’s common stock on each trading day during the 20 consecutive trading days immediately preceding the third business day prior to the Effective Time (the “20-day VWAP”) is less than $46.00 per share, then the holder of each share of Applera common stock which is converted into a right to receive any portion of the merger consideration in the form of shares of the Company common stock will receive, in addition, an amount in cash without interest equal to the product of (x) the portion of a share of the Company common stock which such holder has the right to receive multiplied by (y) the lesser of (A) $46.00 minus the 20-day VWAP and (B) $2.31. In addition, (1) all Applera options will vest and become fully exercisable and converted into options to purchase shares of the Company common stock, (2) shares of Applera restricted stock will become fully vested and treated as shares electing to receive cash and Company shares (“Mixed Consideration Electing Shares”), (3) restricted stock units of Applera will become fully vested, settled in shares of Applera common stock and treated as Mixed Consideration Electing Shares, and (4) each outstanding right to receive shares of Applera common stock pursuant to a stock unit award will be fully vested and settled in Applera common stock.

The Company and Applera have made customary representations, warranties and covenants in the Merger Agreement. The consummation of the merger is subject to, among other things, (1) approval of the Merger Agreement by Applera stockholders, (2) approval by the Company stockholders of the issuance of shares in connection with the merger and of an amendment to the Company’s certificate of incorporation to increase the number of its authorized shares of common stock, (3) consummation by Applera of the redemption of all of the issued and outstanding shares of its Celera Group common stock in exchange for shares of common stock, par value $.01 per share, of Celera Corporation as a result of which Applera’s Celera Group tracking stock business will be split off and owned by former holders of the Celera Group common stock, and (4) regulatory approvals, including expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the European Commission Merger Regulation, as well as other regulatory approval in certain other countries.

Upon completion of the transaction, the Company will change its name to Applied Biosystems, Inc. and will expand its board of directors from nine to 12 members and appoint three of Applera’s current directors to the Company board.

The Merger Agreement contains certain termination rights for both the Company and Applera. Upon termination of the Merger Agreement under certain specified circumstances, the Company or Applera would be required to pay the other a termination fee of $150 million.

On June 11, 2008, the Company entered into a commitment letter, or the Commitment Letter, with Bank of America, N.A., Banc of America Securities LLC, UBS Loan Finance LLC, UBS Securities LLC and Morgan Stanley Senior Funding Inc., or the Commitment Parties, pursuant to which certain of the Commitment Parties will act as the initial lenders under senior secured credit facilities in an aggregate amount of $2.65 billion, consisting of a revolving credit facility of $250.0 million and term facilities aggregating $2.4 billion, or the Credit Facilities. The Credit Facilities, along with cash on hand at the Company, Applera and their respective subsidiaries at the Effective Time, are intended to finance (a) the acquisition of Applera pursuant to the Merger Agreement, (b) the costs and expenses related to the transaction, (c) the repayment of, and termination of, all commitments to make extensions of credit under, certain existing indebtedness of the Company and Applera, other than the Company’s convertibles notes and other exceptions, and (d) the ongoing working capital and general corporate purposes of the combined company.

Investors are cautioned that the representations, warranties and covenants included in the Merger Agreement were made by Applera and the Company to each other. These representations, warranties and covenants were made as of specific dates and only for purposes of the Merger Agreement and are subject to important exceptions and limitations, including a contractual standard of materiality that may be different from that generally relevant to investors, and are qualified by information in confidential disclosure schedules that the parties exchanged in connection with the execution of the Merger Agreement. In addition, the representations and warranties may have been included in the Merger Agreement for the purpose of allocating risk between Applera and the Company, rather than to establish matters as facts.

The foregoing description of the Merger Agreement, the Commitment Letter and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is attached hereto as Exhibit 2.1 and is incorporated by reference herein, and the Commitment Letter, which is attached hereto as Exhibit 10.1 and is incorporated by reference herein.
