“Section 9.1 Term. This Agreement shall become effective as of the Effective Date, and shall remain in full force and effect for a primary term of fifteen (15) years (the “Primary Term”). The Primary Term shall be automatically extended to match any extension to the GPC Term if and only to the extent the GPC Term is extended (as effected in accordance with the terms and conditions of the GPC) to a date beyond the end of the then-current Primary Term.

Notwithstanding the foregoing and for the avoidance of doubt, the Parties acknowledge and agree that any expiration, termination, or suspension of the GPC Term (in each case, as effected in accordance with the terms of the GPC) shall not affect (i.e. shall not shorten or truncate) the Primary Term (as extended to match the GPC Term) or any Annual Renewal.”
