Page 2 - Code of Ethical Business Conduct

Dear Fellow Employees:
Our Ethics Policy – and the shared commitment of each and every one of us to doing
what’s right – has been, and continues to be, the cornerstone of Martin Marietta.
Unethical decisions and actions can hurt not only
you, but fellow employees, our customers, our families,
our shareholders, and obviously the entire company. In
practically no time at all, unethical decisions and actions
destroy the strong reputation for honesty, integrity
and accountability we’ve worked long and hard to build.
Unethical behavior can come in a host of different
forms. While news headlines tend to focus on financial
misconduct, that fact is misplaced decisions can
be made in everything we do, at any level, and no
Martin Marietta employee is totally immune to making
bad decisions.
But, illegal or unethical behavior is never acceptable at Martin Marietta. If you see
or hear something that you feel is wrong, speak up. Talk to your supervisor. Talk to your
local Human Resources representative. Talk to management in your district or division,
or contact our Ethics Hotline.
Your concerns and questions are important and will be taken seriously. It’s important
that you feel comfortable coming forward, without any concerns about retaliation for
doing so. Staying quiet and not reporting questionable behavior can be just as harmful
to Martin Marietta as the bad behavior itself.
Our Ethics Policy was created to serve as a guide in our day-to-day decision-making.
All of us, each and every day, face difficult situations where the “right choice” isn’t
always obvious. Our Ethics Policy is designed to help you make that choice.
Just as with our safety and environmental programs, our ethics program can only be
effective if we all play a real part in it.
Only by rededicating ourselves each and every day to doing what’s right can we
reach the heights I know without a doubt that we’re capable of reaching. I am constantly
impressed by your dedication, drive and determination, and I know you’ll continue to
show that same commitment to ethical behavior in all that you do.
Thanks in advance for your time, attention and effort in this important undertaking.
Sincerely,

C. Howard Nye
Chairman, President and Chief Executive Officer
