Article 12
Revenue Accounting and Calculation of the Salary Cap

Section 1(a)(xii)
All Revenues

For purposes of this Article, and anywhere else stated in this Agreement, revenues shall be accounted for in the manner set forth below.

(a)(xii)

Cancelled Games. If one or more weeks of any NFL season are cancelled or AR for any League Year substantially decreases, in either case due to a terrorist or military action, natural disaster, or similar event, the parties shall engage in good faith negotiations to adjust the provisions of this Agreement with respect to the projection of AR and the Salary Cap for the following League Year so that AR for the following League Year is projected in a fair manner consistent with the changed revenue projection caused by such action.
