The following bulletin was circulated via email to Continental employees on September 7, 2010:

September 7, 2010

EMPLOYEE BULLETIN NO. 19

BROAD BASED STOCK OPTIONS TO BE CONVERTED TO OPTIONS IN

UNITED CONTINENTAL HOLDINGS, INC.; ESPP PROGRAM TO END

This bulletin contains information on two separate programs: the 2005 Broad Based Stock Option Plans and the CO Employee Stock Purchase Plan.

The 2005 Broad Based Employee Stock Option Plan and the 2005 Pilot Supplemental Option Plan

Upon completion of the merger, outstanding broad based stock options granted under the Continental Airlines, Inc. 2005 Broad Based Employee Stock Option Plan and the 2005 Pilot Supplemental Option Plan (collectively, the “Broad Based Plans”) will be converted into options to purchase shares in UAL Corporation, United’s parent company (UAL), which will be renamed United Continental Holdings, Inc. at the time of the merger closing.

The number of shares that can be purchased under the adjusted options will be converted at the merger exchange ratio of 1.05 shares of UAL common stock for every share of CO common stock, and rounded down to the nearest whole share. For example, if, at the time of the merger, you have outstanding options to purchase 100 shares of CO’s common stock, these options will convert to options to purchase 105 shares of UAL common stock. The exercise price under the converted options will also be adjusted by dividing the current exercise price by the exchange ratio (1.05), and rounding up to the nearest whole cent. For example, if the current exercise price under your outstanding CO options were $10.00/share of CO common stock, the converted options would be adjusted to provide for an exercise price of $9.53/share of UAL common stock ($10.00/1.05) upon the completion of the merger.

There will be a brief blackout period at the time of merger closing during which optionees will be restricted from exercising options or selling shares obtained from option exercises so that stock option accounts can be converted. The exact blackout dates have yet to be determined but will be communicated to you in advance of the blackout period.

Other than the changes described above, your outstanding options under the Broad Based Plans will continue to be subject to the same terms. Vested options granted under the Broad Based Plans will remain exercisable until they expire, subject to certain termination rules outlined in your stock option grant document. You can view your stock option account at Morgan Stanley Smith Barney by going to www.benefitaccess.com. For more information, please contact Employee Stock Options Administration at employeestockoptions@coair.com or call 713-324-5021, option 3.

ESPP to End Soon

The merger between CO and UAL will also mean CO’s Employee Stock Purchase Plan (ESPP) will end. The last payroll deduction for the current quarterly purchase period is expected to occur in mid-September, and your accumulated payroll deduction contributions will then be used to buy shares of CO common stock. In connection with the merger, there will be a short blackout period during which participants will be restricted from selling shares in their ESPP accounts so that the shares of CO stock held in ESPP accounts can be converted into shares of the common stock of UAL. The exact blackout dates have not yet been determined, but ESPP participants will be notified in advance of the blackout period.

Participants need not take any action at this time, and Morgan Stanley Smith Barney will continue to maintain participants’ accounts.

On the day we legally merge, CO and United will both be subsidiaries United Continental Holdings, Inc., and the stockholders will own shares in that holding company. Shares of CO stock will be converted into UAL stock at the merger exchange ratio of 1.05 shares of UAL common stock for every share of CO common stock. For example, if you participate in the plan and have 100 shares of CO stock in an ESPP account, those shares will be converted into 105 shares of UAL stock on the date of the merger closing. Upon the closing of the merger, the CO Employee Stock Purchase Plan will terminate.

For more information, participants may refer to a Q&A at Insidecoair > “News and Events” > “Employee Stock Purchase Plan Q&A.” Participants can also contact ESPP Administration at ESPP@coair.com or call 713-324-ESPP (3777).
