May 3, 2010

Dear Valued Supplier:

I am writing to share some significant and exciting news. This morning we announced that we have signed a definitive agreement with United for an all-stock merger of equals, which will create the industry-leading global airline with the world’s most comprehensive network, with ten hubs, including hubs in the four largest cities in the United States. For your convenience, we have attached a copy of the press release.

We believe that the merger with United is the best way to ensure that we remain a strong long-term competitor in the airline industry. As you know, the competitive landscape is changing and today’s announcement is the culmination of a very thorough and diligent review of available options by our Board of Directors. This strategic combination of two of the most respected and compatible global carriers will result in a stronger company, both operationally and financially. Combining our complementary route networks will help us create a world-class airline with tremendous and enduring strengths and will provide the greater scope and scale that is necessary to compete long-term in the rapidly changing global aviation industry.

Glenn Tilton, chairman, president and chief executive officer of UAL Corp., will serve as non-executive chairman of the combined company’s Board of Directors through December 31, 2012 or the second anniversary of closing, whichever is later. Jeff Smisek, Continental’s chairman, president and chief executive officer, will be chief executive officer and a member of the Board of Directors. He will also become executive chairman of the Board upon Tilton’s ceasing to be non-executive chairman.

The company’s name will be United Airlines and the marketing brand will be a combination of the brands of both companies. Aircraft will have the Continental livery, logo and colors, with the United name. Our corporate and operational headquarters will be located in Chicago, with a significant presence in Houston, which will be the combined company’s largest hub. We expect to maintain substantial employment in both locations.

The merger is conditioned on approval by the shareholders of both companies, receipt of regulatory clearance, and certain closing conditions. We hope to have these approvals and clearance and close the merger in the fourth quarter of this year. Until the merger is closed, both airlines will continue to operate independently.

We want you to know that Continental recognizes you – our supplier – as a critical part of the combined company’s future. You play a pivotal role in the successful operations of our company and we look forward to maintaining our valuable relationship with you while we remain focused on operating business as usual and continuing to offer superior service to our customers.

Please do not hesitate to contact your representative at Continental with any questions. For additional information on the merger, we encourage you to go to www.unitedcontinentalmerger.com – we will be updating it regularly.

We value and appreciate your services. Thank you for your ongoing support.

Sincerely,

Katrina D. Manning
Vice President, Corporate Purchasing and Material Services
