For the avoidance of doubt, the Parties acknowledge and agree that (i) with respect to the Parties’ objectives under this Section 12.1, BASF would not unreasonably withhold its approval of any manufacturing arrangement which is materially favorable commercially for AMVAC, however, BASF would not be required to agree to any future terms and conditions which might compromise, in BASF’s reasonable opinion, any of BASF’s or its Affiliates’ industrial or intellectual property rights and (ii) notwithstanding any future terms and conditions to which the Parties may agree that AMVAC has the right to manufacture or have manufactured Compound TGAI and/or Products in the Territory, the provisions of Section 5.6 of this Agreement would remain in full force and effect.

12.2 [*]. If at any time during the Term BASF decides to cease [*] of Compound TGAI and products containing either such Compound TGAI or other Compound technical form of active ingredient as an active ingredient globally (for purposes of this Agreement only and subject to the proviso at the end of this sentence, the “Compound Business”) and to sell the Compound Business (subject to the proviso at the end of this sentence, a “[*]”) and elects to [*] this Agreement pursuant to [*], BASF shall provide written notice thereof to AMVAC (the “[*] Notice”); provided, however, that the Parties acknowledge, understand, and agree that the composition of assets and intangibles, if any, comprising the “Compound Business” is at the sole and exclusive discretion of BASF and its Affiliates; and, provided, further, that a [*] shall be deemed to mean only a [*] from the Compound Business.

Upon receipt of the [*] Notice, AMVAC shall have the [*], but not the obligation, to offer to purchase such Compound Business by providing a sufficiently detailed written notice of AMVAC’s offer to BASF in accordance with the terms and conditions of the [*] Notice. This Article XII shall not be construed as precluding BASF from either [*] any Person’s offer in connection with the Compound Business, a [*], or otherwise; provided, however, that in the event that BASF receives any such offer it shall advise AMVAC thereof and AMVAC shall have the right to submit an offer or, in the case of a [*], a second offer. If in the reasonable opinion of BASF the [*] received from AMVAC and any Person are equivalent in all material respects, BASF shall [*] with AMVAC with respect to acquisition of the Compound Business.
