“cornerstone sponsorship proceeds” means, for any such stadium, the six (6) stadium-related sponsorships for new stadiums, and, alternatively, four (4) stadiumrelated sponsorships for stadiums with renovation project(s), in each case that exceeds the threshold, with respect to sponsorship elements/deliverables comparable to those in existing cornerstone sponsorship agreements other than the naming rights partner, where such sponsorship shall be used to support the construction or renovation project. Clubs shall be required to declare which sponsorships, meeting this definition, shall be considered “cornerstone sponsorships” upon execution of such sponsorship agreement. This declaration must be made within two years of the completion of all phases of such construction or renovation project. Cornerstone sponsorships may only be replaced upon expiration of the cornerstone sponsorship agreement, unless a cornerstone sponsor becomes unable or unwilling to meet its obligations under the agreement. At no time may a Club have more than six (6) or four (4) cornerstone sponsorships, as applicable, regardless of the number of construction/renovation projects that have been approved.
