Here is the clause:
ARTICLE XII
RIGHT TO MATCH
12.1 During the one (1) year period after conclusion of the Term for any reason whatsoever (the "Matching Period"), ZUFFA shall have the option to match the financial terms and conditions of any offer made to Fighter for an Other Bout as defined in Section 3.6 of this Agreement. Fighter shall not accept any offer or enter into a contract or agreement with any other promotional entity during the Matching Period without complying with this Section 12.1. Prior to acceptance of any Offer made during
the Matching Period, Fighter shall first deliver to ZUFFA a written notice of all material financial terms and conditions of the offer, including, but not limited to, the identity of the promotional entity making the offer. Such notice shall constitute an exclusive, irrevocable offer (the "Fighter Offer") to contract with ZUFFA on the same financial terms and conditions. ZUFFA shall have fifteen (15) business days following receipt of the Fighter Offer in which to accept the financial terms of the Fighter Offer. If ZUFFA does not accept the Fighter Offer, Fighter may then accept the offer without modification during the ten (10) business day period following expiration of the Fighter Offer (the "Contract Period"). If the offer is modified in any material way, such modification shall give rise to another Fighter Offer on such modified terms and conditions and ZUFFA shall have the option to match the terms of the offer, as modified in accordance with the terms and conditions of this Section 12.1. If Fighter has not contracted with a third party on or before the conclusion of the Contract Period, then all rights granted to ZUFFA pursuant to this Section 12.1 shall be automatically reinstated.
