Bidder shall not discriminate against any employee or applicant for employment to be employed in the submission of this Proposal or in performance of the duties necessitated by an award of the proposed contract with respect to his or her hire, tenure, terms, conditions or privileges of employment, or any matter directly or indirectly related to employment, because of his or her race, color, religion, national origin, ancestry, gender, height, weight, marital status, age, except where a requirement as to age is based on a bona fide occupational qualification, or disability that is unrelated to the individual's ability to perform the duties of a particular job or position.

The Academy reserves the right to waive any informalities or immaterial omissions or defects not involving prices, time or changes in the work and to reject any or all proposal, if to do so is deemed in the best interest of the Academy.

This RFP does not include every term and provision which shall be included in the formal agreement. In the event that the bidder fails to execute the formal agreement within 14 days of its presentment by the Academy, the Academy may reject the selected bidder, and proceed to accept another qualified proposal, or reject all proposals.

A copy of a bidder’s suggested terms and conditions may be submitted with bidder’s proposal, however, neither the Academy’s acceptance of any proposal nor award of any contract pursuant to this RFP shall be construed as any definitive acceptance by the Academy of Bidder’s suggested terms and conditions.
