In order to allow shareholders of Invitrogen and Applied Biosystems more time to consider the merger agreement amendment, the parties have agreed to delay their previously scheduled special stockholder meetings in connection with the merger. The special stockholder meetings for both Invitrogen and Applied Biosystems will now be held on October 28, 2008. Applied Biosystems will convene its scheduled October 16, 2008 special meeting for the sole purpose of adjourning the meeting, and Invitrogen's scheduled October 16, 2008 special meeting will be postponed.

Although voting on the merger is still in process, stockholders have thus far overwhelmingly voted in favor of the merger. Any proxies or votes already submitted by stockholders in connection with the special meetings will remain valid; therefore, there is no need to for any stockholders to vote again. In addition, any elections to receive cash, stock or mixed consideration that have already been submitted by Applied Biosystems stockholders will remain valid and will be unaffected by the delay in holding the special meetings or the amendment of the merger agreement.

Invitrogen and Applied Biosystems will be mailing a supplement to the joint proxy statement/prospectus in connection with the merger that was previously sent to stockholders of record as of the close of business on the September 5, 2008 record date. This supplement will provide detailed information regarding the amendment to the merger agreement and the tax implications of the merger. Stockholders are encouraged to read the supplement in its entirety, as well as the joint proxy statement / prospectus. The supplement will be filed with the Securities Exchange Commission and an electronic version will be available on each company's website.

Stockholders who have not yet voted may do so until the special stockholder meetings, and all proxies will remain revocable until the applicable meeting has been concluded. Applied Biosystems stockholders who have not made their cash, stock or mixed consideration elections may do so until the election deadline two business days prior to the closing of the merger. All elections will remain revocable until the election deadline.

The parties do not expect the delay in holding the special meetings or the amendment of the merger agreement to delay the projected closing date of the merger, which is still expected to occur in November. In addition to the approval of Applied Biosystems and Invitrogen stockholders, the merger is conditioned on, among other matters, receipt of antitrust clearance under the European Council Merger Regulation.

The special meeting of Invitrogen shareholders to consider the proposed acquisition of Applied Biosystems will now be held on October 28, 2008, at 9:30 a.m. Pacific Standard Time at Invitrogen's headquarters, 5781 Van Allen Way, Carlsbad, CA 92008. Applied Biosystems' special meeting of shareholders will now be held on October 28, 2008, at 9:00 a.m. Eastern Daylight Time at the headquarters of Applied Biosystems, 301 Merritt 7, Norwalk, CT 06851.

Under the U.S. tax code, if the merger qualifies as a tax-free reorganization for tax purposes, gain realized by a U.S. holder of Applied Biosystems stock will only be taxable to the extent of the cash portion of the merger consideration. Loss, if any, will not be recognized at the time of the merger. If the merger does not qualify as a tax-free reorganization, then U.S. holders of Applied Biosystems stock will recognize gain (or loss) to the extent that the value of the cash and stock consideration they receive exceeds (or is less than) the tax basis of the Applied Biosystems shares they own. There should be no consequences for U.S. holders of Invitrogen common stock if the merger does not qualify as a tax-free reorganization. Stockholders are encouraged to obtain the advice of their personal tax advisors to make their own determination on the tax consequences to them of the merger.

Invitrogen and Applied Biosystems have received opinions from their respective counsel that, regardless of whether the merger qualifies as a tax-free reorganization, the merger will not be taxable to either company.
