(2) If shares of Company common stock were disposed of pursuant to the offer (the Exchange Offer) by McDermott Technology, B.V., a wholly owned subsidiary of McDermott, to exchange each share of CB&I common stock that was validly tendered and not properly withdrawn in the Exchange Offer for the right to receive 0.82407 shares of McDermott common stock, then upon the closing of the Combination, each such tendered share was exchanged into the right to receive 0.82407 shares of McDermott common stock.If shares of Company common stock were not validly tendered in the Exchange Offer, shares of Company common stock were disposed of pursuant to a series of transactions involving a merger, share sale and liquidation, as a result of which former Company shareholders who did not validly tender in the Exchange Offer became entitled to receive, in respect of each former share of Company common stock, 0.82407 shares of McDermott common stock.
(3) Pursuant to the BCA, all vested shares held by non-employee directors for which settlement has been deferred were cancelled in exchange for the right to receive (a) a number of shares of McDermott common stock equal to the number of deferred shares of Company common stock multiplied by 0.82407, rounded to the nearest whole number of shares plus (b) a cash amount equal to the amount of accrued dividend equivalents.
