A Tribute to Carol

September 21, 2009

Dear National Colleagues:

With deep regret, I write to inform you that today, September 21, our
friend and colleague Carol Marshall passed away and has gone home to the
Lord. Carol has suffered with a terminal illness for the better part of
this year, and passed away peacefully in hospice care with her family at
her side.

Many of you got to know Carol over the past twelve months as she guided
National Air Cargo through the rigors of initiating our Ethics and
Proper Business Conduct programs throughout the global offices. All of
us who knew her can see her bright smile and positive voice, encouraging
us and coaching us. She leaves a very strong legacy of proper business
behaviors and expectations to National Air Cargo. I now encourage all of
us to stand up and proudly live the "work ethics" Carol so positively
displayed. Her impact on National Air Cargo and National Airlines, at an
extremely critical crossroad in our company's history, will live on and
on. Let's make her proud by working as she would expect.

Carol was recognized as an expert in the area of Compliance, Business
Ethics, and Workplace Conduct. She had established internationally
recognized compliance and ethics programs at a number of corporations
and worked closely with government entities and non-government
organizations to promote the highest standards of ethical conduct in
multi-national corporations. She received her law degree, and was
formerly a senior vice president at MCI and at Lockheed Martin,
specializing in Ethics and Compliance.

Carol is survived by her husband Frank Marshall, and children Charles,
Christine, and Andrew. Our thoughts and prayers go out to Frank and
family at this difficult time. A memorial service will be held in
Northern Virginia on Thursday September 24th.
