Notwithstanding [Section 6.09], any Producer that commenced a production run at a Mine prior to December 20, 2016 in accordance with the Historical Article VI Provisions for purposes of demonstrating a Post-Expansion Audit Amount for a Major Expansion (an “Exempt Producer”) may elect not to be subject to [Section 6.09] in respect of such Major Expansion, in which case:

Notwithstanding [Section 6.16], in the event a consultation process conducted in accordance with [Section 6.15(h)] identifies issues which cannot be resolved within ten (10) business days from the date the consultation takes place (the “Consultation Completion Deadline”), the parties hereto shall confer to determine whether the results of the Engineering Audit should be provisionally accepted pending ultimate resolution, or held in abeyance pending such resolution, considering the materiality of the issue, the magnitude of the adjustment and the anticipated time required to resolve the issues. If the parties hereto cannot reach resolution of these matters, the Expanding Producer, regardless of whether the Expanding Producer previously confirmed (or was deemed to confirm) to [[Organization A:Organization]] that it accepted the results of the Engineering Audit Report, may elect to apply the Production Run Procedures (in which case, the Expanding Producer shall be considered an Electing Producer) or, if no such election is made, all questions shall immediately proceed to binding arbitration and resolved no later than one (1) month from the Consultation Completion Deadline with retroactive effect to the date that would otherwise apply pursuant to [Section 6.16] (being January 1 or July 1, as applicable). If the Expanding Producer is not satisfied with the results of such arbitration, the Expanding Producer, regardless of whether the Expanding Producer previously confirmed (or was deemed to confirm) to [[Organization A:Organization]] that it accepted the results of the Engineering Audit Report, may elect to apply the Production Run Procedures (in which case, the Expanding Producer shall be considered an Electing Producer).

Such deferral shall only be effected to the extent required to avoid adverse tax treatment to the Non-Employee Director, including (without limitation) the additional twenty percent (20%) tax for which the Non-Employee Director would otherwise be liable under [section 409A(a)(1)(B)] of the Code in the absence of such deferral. Upon the expiration of the applicable deferral period, any compensation or benefits which would have otherwise been paid during that period (whether in a single sum or in installments) in the absence of this Section 17 shall be paid to the Non-Employee Director or his or her beneficiary in one lump sum.
