This Amendment No. 10 amends and supplements the Tender Offer Statement on Schedule TO filed with the Securities and Exchange Commission (the “SEC”) on July 15, 2011, as amended by Amendment No. 1 filed with the SEC on July 18, 2011, by Amendment No. 2 filed with the SEC on July 19, 2011, by Amendment No. 3 filed with the SEC on July 21, 2011, by Amendment No. 4 filed with the SEC on July 25, 2011, by Amendment No. 5 filed with the SEC on July 28, 2011, by Amendment No. 6 filed with the SEC on July 29, 2011, by Amendment No. 7 filed with the SEC on August 4, 2011, by Amendment No. 8 filed with the SEC on August 16, 2011 and by Amendment No. 9 filed with the SEC on August 16, 2011 (which, together with any subsequent amendments or supplements thereto, collectively constitutes this “Schedule TO”). This Schedule TO relates to the tender offer by IVD Acquisition Corporation, a Georgia corporation (“Purchaser”) and a wholly owned indirect subsidiary of IVD Holdings Inc., a Delaware corporation (“Parent”), which is controlled by TPG Partners VI, L.P., a Delaware limited partnership (“Sponsor”), for all of the outstanding shares of common stock, par value $0.10 per share (“Shares”), of Immucor, Inc., a Georgia corporation (“Immucor”), at a price of $27.00 per share, net to the seller in cash, without interest thereon and less any applicable withholding taxes, upon the terms and conditions set forth in the offer to purchase dated July 15, 2011 (the “Offer to Purchase”), a copy of which is attached as Exhibit (a)(1)(A), and in the related letter of transmittal (the “Letter of Transmittal”), a copy of which is attached as Exhibit (a)(1)(B), which, together with any other related materials, as each may be amended or supplemented from time to time, collectively constitute the “Offer.”

All the information set forth in the Offer to Purchase is incorporated by reference herein in response to Items 1 through 9 and Item 11 of this Schedule TO, and is supplemented by the information specifically provided in this Schedule TO.

This Amendment No. 10 is being filed to amend and supplement Items 1, 4, 11 and 12 as reflected below.

-3-

Items 1, 4 and 11.

Items 1, 4 and 11 of this Schedule TO are hereby amended and supplemented as follows:

“The Offer and withdrawal rights expired at 5:00 p.m., Atlanta, Georgia time, on August 18, 2011. The Depositary has advised us that 61,549,994 Shares were validly tendered and not validly withdrawn as of 5:00 p.m., Atlanta, Georgia time, on August 18, 2011, representing a total of approximately 87% of the outstanding Shares on a fully-diluted basis. Purchaser has accepted for payment all Shares that were validly tendered and not validly withdrawn, and payment for such Shares has been or will be made promptly in accordance with the terms of the Offer. Purchaser also exercised the Top-Up Option, pursuant to which Immucor issued 21,390,443 additional Shares to Purchaser at a price per Share equal to the Offer Price, which, together with the Shares purchased in the Offer, represented at least one Share more than 90% of the outstanding Shares on a fully-diluted basis.

As a result of the purchase of Shares in the Offer and the issuance of Shares pursuant to the Top-Up Option, Purchaser had sufficient voting power to approve the Merger without the affirmative vote of any other shareholder of Immucor. Accordingly, Purchaser has effected a “short-form” merger in which Purchaser merged with and into Immucor, with Immucor surviving the Merger and continuing as an indirect wholly owned subsidiary of Parent. In the Merger, each Share issued and outstanding immediately prior to the effective time of the Merger, other than Shares owned by Parent, Purchaser or any other direct or indirect wholly owned subsidiary of Parent (including, without limitation, Shares purchased in the Offer and pursuant to the Top-Up Option) and Shares owned by Immucor or any of its direct or indirect wholly owned subsidiaries (in each case not held on behalf of third parties), was automatically converted, subject to dissenters’ rights pursuant to Article 13 of the GBCC, into the right to receive the Offer Price in cash, without interest thereon and less any applicable withholding taxes. All Shares converted into the right to receive the Offer Price have been canceled and cease to exist. August 18, 2011 was the last day Shares traded through Nasdaq.

On August 19, 2011, TPG Capital and Immucor issued a joint press release announcing the expiration and results of the Offer and the completion of the Merger. The full text of the press release is attached hereto as Exhibit (a)(5)(J) and is incorporated by reference.”
