Such records shall be made available to Boeing for audit during reasonable times upon request, but not beyond one year after final payment. A sample invoice format is included as Exhibit 1.

You will, for the term of this Agreement and thereafter, preserve in confidence, not disclose to any third party, and not use without the prior written permission of Boeing (except in the performance of work for Boeing covered by this Agreement) any and all such Proprietary Information. You acknowledge that in your role as a consultant you may have access to information that is not available to the general public and that you are responsible for compliance with all state and federal regulations regarding securities trading. You will, in the performance of this Agreement, refrain from the unlawful or unauthorized use or disclosure of any trade secrets and/or confidential information and from the infringement of any patents or copyrights. You also agree to ensure that Boeing may make unlimited use of, freely disclose copy, display, distribute, perform, and make derivative works from all information and materials disclosed or otherwise provided to Boeing in connection with this Agreement, without incurring any obligation or liability to you or to any other person or entity.
