Includes 2,000 shares and 370 shares acquired under the Issuer's 2019 Employee Stock Purchase Plan on May 20, 2024 and September 13, 2024, respectively. Pursuant to the Agreement and Plan of Merger dated June 17, 2024, between the Issuer, Boston Scientific Corporation and Seminole Merger Sub, Inc, (the "Merger Agreement"), each share of Issuer common stock was canceled and converted into the right to receive $27.50 per share in cash (the "Merger Consideration"), without interest and subject to applicable withholding taxes. Pursuant to the Merger Agreement, each RSU was canceled and converted into the right to receive an amount in cash, without interest, equal to the product of (i) the Merger Consideration and (ii) the aggregate number of shares underlying the RSUs, less applicable taxes and authorized deductions. Immediately prior to the effective time of the merger, certain RSUs subject to the achievement of performance-based criteria, or PSUs, were deemed achieved and certified by the Issuer's compensation committee. Pursuant to the Merger Agreement, each PSU was canceled and converted into the right to receive an amount in cash, without interest, equal to the product of (i) the Merger Consideration and (ii) the aggregate number of shares underlying the PSUs, less applicable taxes and authorized deductions. These shares are held directly by the Buchanan Grandchildren's Irrevocable Trust, for which the reporting person serves as a co-trustee. The shares subject to the option are fully vested and immediately exercisable. Pursuant to the Merger Agreement, the option was cancelled in exchange for a cash payment of $39,982.50, which represents the difference between (i) the amount by which the Merger Consideration exceeded the exercise price of the option per share option and (ii) the aggregate number of shares remaining issuable upon exercise of the option, less applicable taxes and authorized deductions. /s/ Mhairi Jones, by power of attorney 2024-09-18
