| F1 | Pursuant to the terms of the Agreement and Plan of Merger (the "Merger Agreement"), dated as of April 2, 2024, by and among the Issuer, Schlumberger Limited ("SLB"), Sodium Holdco, Inc. and Sodium Merger Sub, Inc. ("Merger Sub"), pursuant to which Merger Sub merged with and into the Issuer with the Issuer continuing as the surviving corporation and an indirect wholly owned subsidiary of SLB (the "Merger"). |
| F2 | Pursuant to the Merger Agreement, among other things, (i) each outstanding share of common stock of the Issuer ("Common Stock") prior to the effective time of the Merger (the "Effective Time") was cancelled and converted into the right to receive 0.735 shares of SLB common stock ("SLB Common Stock" and such ratio, the "Exchange Ratio") and if applicable, cash in lieu of fractional shares and (ii) each outstanding restricted stock unit of the Issuer (an "RSU") was assumed and converted into a restricted stock unit award to acquire shares of SLB Common Stock, on the same terms and conditions that applied to each RSU immediately prior to the Effective Time (an "SLB RSU Award") except that, as of the Effective Time, the number of shares of SLB Common Stock subject to an SLB RSU Award is equal to the product of (A) the number of shares of Common Stock underlying the RSU multiplied by (B) the Exchange Ratio, rounded down to the nearest whole share. |
| F3 | Pursuant to the Merger Agreement and Section 280G Mitigation Agreement dated December 23, 2024 between the Issuer and the Reporting Person, each outstanding restricted stock award of the Issuer was assumed and converted at the Effective Time into restricted shares of SLB Common Stock, as adjusted by the Exchange Ratio. |
| F4 | Pursuant to Merger Agreement, each stock appreciation right of the Issuer (each, a "SAR") that was outstanding immediately prior to the Effective Time was terminated and cancelled in exchange for an amount in cash equal to the product of (i) the number of shares of Common Stock underlying such SAR multiplied by (ii) the excess, if any, of the closing price over the exercise or reference price of such SAR. The closing price was the volume-weighted average closing sale price of a share of Common Stock as reported on Nasdaq for the 15 consecutive full trading days ending at the close of trading on the full trading day immediately preceding the closing date of the Merger. |
