Proposal 3 - Combination-Related Compensation Proposal: Proposal to approve, on a non-binding, advisory basis, the compensation that will or may become payable by Endo or its subsidiaries to its named executive officers in connection with the consummation of the Transaction (the “Combination-Related Compensation Proposal”).
