Boeing Stock Units. Boeing Stock Units granted under the Plan prior to the May 1, 2006 shall continue to be subject to the provisions of the Plan as in effect immediately prior to such date.

Stock Units. Dividend Equivalents shall be credited with respect to each Stock Unit credited to a Director on each dividend record date. Such Dividend Equivalents shall themselves be converted into Stock Units as of the dividend payment by dividing the amount of the Dividend Equivalents by the Value of the Company’s common stock as of the dividend payment date. Dividend Equivalents shall be credited on Stock Units attributable to a deferral of Director’s Fees and, except as otherwise provided by the terms of a Deferred Equity-Based Award, Stock Units attributable to Deferred Equity-Based Awards.

Stock Units. Each Stock Unit shall represent an unfunded and unsecured promise by the Company to issue cash equal in value to the Stock Unit. Participants holding Stock Units (or fractions thereof) shall earn dividend equivalents paid in the form of additional Stock Units added to their account. The number of Stock Units so added shall equal the dividend on a Share multiplied by the number of Stock Units held by the Participant on the record date for such dividend, divided by the Fair Market Value of a Share on the last Trading Day in the calendar month in which the record date for such dividend occurs. The Stock Units shall be credited to a Participant's account on the day the number of Stock Units is determined.

The number of shares of Boeing stock that could be bought with such cash dividends will be calculated based on the “Fair Market Value” of Boeing stock on the applicable dividend payment date. “Fair Market Value” here means the average of the high and the low per share trading prices for Boeing stock as reported in The Wall Street Journal for the specific dividend payment date, or in such other source as the Company deems reliable.

While RSUs are in your account, they will earn dividend equivalents in the form of additional RSUs. Specifically, as of each dividend payment date for Boeing stock, your RSU account will be credited with additional RSUs (“dividend equivalent RSUs”) equal in number to the number of shares of Boeing stock that could be bought with the cash dividends that would be paid on the RSUs in your account if each RSU were a share of Boeing stock. The number of RSUs that results from the calculation will be to two decimal places.

Restricted Stock Units. The Administrator is authorized to grant Restricted Stock Units to any Eligible Individual. The number and terms and conditions of Restricted Stock Units shall be determined by the Administrator. The Administrator shall specify the date or dates on which the Restricted Stock Units shall become fully vested and nonforfeitable, and may specify such conditions to vesting as it deems appropriate, including conditions based on one or more Performance Criteria or other specific criteria, including service to the Company or any Affiliate, in each case, on a specified date or dates or over any period or periods, as determined by the Administrator. The Administrator shall specify, or permit the Participant to elect, the conditions and dates upon which the Shares underlying the Restricted Stock Units shall be issued, which dates shall not be earlier than the date as of which the Restricted Stock Units vest and become nonforfeitable and which conditions and dates shall be consistent with the applicable provisions of Section 409A of the Code or an exemption therefrom. On the distribution dates, the Company shall issue to the Participant one unrestricted, fully transferable Share (or the Fair Market Value of one such Share in cash) for each vested and nonforfeitable Restricted Stock Unit.

As of the Effective Date, the RSU grant shall be modified to vest on December 31, 2020.

Each Outside Director will receive shares of Common Stock for their Restricted Stock Units on the fifth business day of the calendar quarter following the quarter of his or her separation from Board service.
