Dear Xxxxx:

As you know, UAL Corporation, a Delaware corporation (“UAL”), Continental Airlines, Inc., a Delaware corporation (“Continental”) and JT Merger Sub Inc., a Delaware corporation and wholly owned subsidiary of UAL (“Merger Sub”), have entered into an Agreement and Plan of Merger, dated as of May 2, 2010 (the “Merger Agreement”), pursuant to which Merger Sub will be merged with and into Continental (the “Merger”) and, as a result of which, Continental will become a wholly owned subsidiary of UAL (which will be renamed United Continental Holdings, Inc. (“United Continental”)) upon the effective time of the Merger (the “Effective Time”). Upon the Effective Time, you will cease to be the Chief Executive Officer of UAL and United Airlines, Inc. (“UA”, and UAL and UA sometimes collectively referred to as “United”) and the President of UAL, you will retire from United, and you will become non-executive chairman (“Chairman”) of the Board of Directors of United Continental (the “United Continental Board”). It is anticipated that you will serve as Chairman of the United Continental Board until the later of (a) the second anniversary of the Effective Time and (b) December 31, 2012 (the later of such dates, the “Chairman Retirement Date”).

This letter agreement (this “Letter Agreement”) sets forth the terms of your compensation as Chairman of the United Continental Board. It is hereby agreed by United and you as follows:

1. Standard Non-Employee Director Compensation. While serving as Chairman, you will receive the same compensation paid to other non-employee directors of the United Continental Board.

2. Additional Annual Cash Retainer. Until the Chairman Retirement Date (or such earlier date on which your service as Chairman terminates), you will receive an additional annual cash retainer of $600,000, payable pursuant to the same schedule as the regular annual cash retainer paid to other non-employee directors of the United Continental Board.

3. Additional Annual Equity Retainer. At or promptly following the first meeting of the United Continental Board that occurs following the Effective Time, you will receive an additional equity retainer of restricted stock units of United Continental common stock (“RSUs”) with a grant date value of $150,000 pursuant to the 2006

Director Equity Incentive Plan, as amended (or any successor plan thereto) (the “DEIP”). At or promptly following the first meeting of the United Continental Board that occurs following the first anniversary of the Effective Time, provided that your service as Chairman has not terminated, you will receive an additional equity retainer of RSUs with a grant date value of $150,000 pursuant to the DEIP. The number of RSUs that you will receive on each grant date will equal the quotient of (A) $150,000 and (B) the closing price of United Continental common stock on the New York Stock Exchange on the applicable grant date (rounded down to the nearest whole number). The RSUs will vest upon the earliest of (a) the first anniversary of the applicable grant date, (b) the Chairman Retirement Date, (c) termination of your service as Chairman due to your death, Disability or removal without Cause (including, without limitation, as a result of your failure to be re-elected to the United Continental Board by United Continental’s stockholders), (“Disability” and “Cause”, each as defined in the Employment Agreement (as defined in Section 15 below)) and (d) your retirement as Chairman with the consent of the United Continental Board (each such termination in the foregoing clauses (c) and (d), a “Qualifying Chairman Termination”). For the avoidance of doubt, in the event that your service as Chairman terminates prior to the Chairman Retirement Date for any reason other than a Qualifying Chairman Termination, you will immediately forfeit any unvested RSUs and will have no further rights with respect thereto.

4. Travel Privileges. While serving as Chairman, you will receive the same travel privileges provided to other non-employee directors of the United Continental Board. Upon termination of your service on the United Continental Board, you will receive the same travel privileges provided to other non-employee directors who retire from the United Continental Board following the Effective Time.

5. Company Car and Driver. Until the Chairman Retirement Date (or such earlier date on which your service as Chairman terminates), you will be provided with the use of a car and driver for both business and personal use at a level consistent with the level provided to you by United immediately prior to the Effective Time.

6. Office Space and Administrative Support. Until the Chairman Retirement Date (or such earlier date on which your service as Chairman terminates) and for a period of ten years thereafter, you will be provided with (a) office space at 00 X. Xxxxxx Xxxxx, 00xx xxxxx, Xxxxxxx, XX or at such other location as may be agreed to by you and United Continental from time to time and (b) full-time administrative support.
