On December 11, 2019, the compensation committee (the “Committee”) of the board of directors of WellCare Health Plans, Inc. (the “Company”) considered the potential adverse tax consequences to the Company and to certain of the executive officers of the Company, including Messrs. Kenneth Burdick and Michael Polen, and Mses. Kelly Munson and Anat Hakim (collectively, the “Impacted Officers”), under Sections 280G and 4999 of the U.S. Internal Revenue Code, as amended, resulting from the treatment of potential payments that may be made to each of the Impacted Officers in connection with the pending merger of the Company with and into a wholly-owned subsidiary of Centene Corporation (“Centene”). In order to mitigate these potential adverse tax consequences, the Committee has elected to accelerate payment to the Impacted Officers of the non-equity incentive cash award earned by each of the Impacted Officers in respect of the Company’s 2019 fiscal year that would have otherwise become payable in 2020 into December 2019, and to accelerate vesting of certain amounts of previously granted time-based restricted stock unit awards and performance-based restricted stock unit awards, in each case, that would have otherwise vested or become payable in 2020 into December 2019, as follows: (a) for Mr. Burdick, certain restricted stock units and performance stock units that otherwise would have vested on March 1, 2020; (b) for each of Ms. Munson and Mr. Polen, restricted stock units that otherwise would have vested on March 1, 2020; and (c) for Ms. Hakim, restricted stock units and performance stock units that otherwise would have vested on either March 1, 2020 or September 26, 2020.

unexpected costs, charges or expenses resulting from the Transaction; (x) the inability to retain key personnel; (xi) disruption from the announcement, pendency and/or completion of the Transaction, including potential adverse reactions or changes to business relationships with customers, employees, suppliers or regulators, making it more difficult to maintain business and operational relationships; and (xii) the risk that, following the Transaction, the combined company may not be able to effectively manage its expanded operations.

Additional factors that may cause actual results to differ materially from projections, estimates, or other forward-looking statements include, but are not limited to, the following: (i) the Company’s progress on top priorities such as integrating care management, advocating for the Company’s members, building advanced relationships with providers and government partners, ensuring a competitive cost position, and delivering prudent, profitable growth, (ii) the Company’s ability to effectively identify, estimate and manage growth, (iii) the ability to achieve accretion to the Company’s earnings, revenues or other benefits expected, (iv) disruption to business relationships, operating results, and business generally of the Company, (v) potential reductions in Medicaid and Medicare revenue, (vi) the Company’s ability to estimate and manage medical benefits expense effectively, including through its vendors, (vii) the Company’s ability to negotiate actuarially sound rates, especially in new programs with limited experience, (viii) the Company’s ability to improve healthcare quality and access, (ix) the appropriation and payment by state governments of Medicaid premiums receivable, (x) the outcome of any protests and litigation related to Medicaid awards, (xi) the approval of Medicaid contracts by the Centers for Medicare & Medicaid Services, (xii) any changes to the programs or contracts, (xiii) the Company’s ability to address operational challenges related to new business and (xiv) the Company’s ability to meet the requirements of readiness reviews.
