Moreover, information concerning the subject matter of the representations and warranties may change after the date of the applicable agreement, which subsequent information may or may not be fully reflected in the parties’ public disclosures. Accordingly, such agreements are included with this filing only to provide investors with information regarding the terms of those agreements, and not to provide investors with any other factual information regarding the parties, their respective affiliates or their respective businesses. These agreements should not be read alone, but should instead be read in conjunction with the periodic and current reports and statements that the AbbVie and/or its subsidiaries file with the Securities and Exchange Commission.
