        <footnote id="F1">The reporting person acquired these Phantom Stock Units under the UTC Board of Directors Deferred Stock Unit Plan (the &quot;Plan&quot;) in connection with the reporting person's annual compensation for service as a non-employee director. The Plan provides for payment of a portion or all of the annual compensation in deferred stock units. Upon retirement or termination, the stock units in the director's account under the Plan are converted into an equal number of shares of common stock that, at the director's previous election, are distributed either in a lump-sum or in installments.</footnote>
