 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 Amendment, except as otherwise set forth below. This Amendment should be read together with the Schedule TO. Capitalized terms used and not otherwise defined in this Amendment have the meanings given to such terms in the Offer to Purchase. Items 1 through 9 and Item 11. The Offer to Purchase and Items 1 through 9 and Item 11 of the Schedule TO, to the extent such Items incorporate by reference the information contained in the Offer to Purchase, are hereby amended and supplemented as follows:

| (1) | The Offer and withdrawal rights expired at 5:00 P.M., Eastern Time, on July 17, 2025 (such date and time,                                                                                                                                            
 the “Expiration Time”), and the Offer was not extended. Purchaser was advised by the Depositary that, as of the Expiration Time, a total of 45,991,262 Shares had been validly tendered into and not validly withdrawn pursuant to the Offer,        
 which together with the Shares owned by Parent and its wholly owned subsidiaries (including Purchaser), represent approximately 70.9% of the aggregate number of Shares then outstanding. Accordingly, the number of Shares validly tendered and not 
 validly withdrawn pursuant to the Offer satisfied the Minimum Tender Condition.                                                                                                                                                                      |

Purchaser has irrevocably accepted for payment, and has stated it will promptly pay for, all Shares validly tendered and not validly withdrawn pursuant to the Offer.

As a result of its acceptance of the Shares tendered pursuant to the Offer and in accordance
with Section 251(h) of the DGCL, Purchaser owns a number of Shares that, together with the Shares owned by Parent and its wholly owned subsidiaries, is greater than the percentage of Shares that would be required to adopt the Merger Agreement
by a vote of the stockholders of the Company. Pursuant to Section 251(h) of the DGCL, subject to the satisfaction of the remaining conditions set forth in the Merger Agreement, Parent, Aventis and Purchaser intend to complete the acquisition of
the Company through the Merger, as promptly as practicable and without a meeting of stockholders of the Company. At the Effective Time and as a result of the Merger, each Share issued and outstanding immediately prior to the Effective Time will be
converted into the right to receive the Offer Consideration
