Please furnish copies of the enclosed materials to those of your clients for whom you hold Shares registered in your name or in the name of your nominee.

The Offer is being made pursuant to the Agreement and Plan of Merger, dated December 14, 2020 (as it may be amended from time to time, the “Merger Agreement”), by and among Prevail, Lilly and Purchaser pursuant to which, after consummation of the Offer and provided that there are no legal restraints preventing or prohibiting the Merger, Purchaser will merge with and into Prevail pursuant to Section 251(h) of the General Corporation Law of the State of Delaware, as amended (the “DGCL”), upon the terms and subject to the conditions set forth in the Merger Agreement, with Prevail continuing as the surviving corporation and becoming a wholly-owned subsidiary of Lilly (the “Merger”).

The Board of Directors of Prevail has unanimously: (1) approved, declared advisable and adopted the Merger Agreement; (2) determined that the Merger Agreement and the transactions contemplated by the Merger Agreement, including the Offer and the Merger, are fair to, and in the best interests of, Prevail and the holders of Shares; and (3) resolved to recommend that the holders of the Shares accept the Offer and tender their Shares pursuant to the Offer.
