“(vii)    the amount of “run rate” net cost savings, synergies and operating expense reductions related to (x) the Transactions that are reasonably identifiable and projected by the Borrower in good faith to result from (and are reasonably attributable to (in the good faith determination of the Borrower)) actions that have been taken or committed to be taken or with respect to which substantial steps have been taken or are expected to be taken (in the good faith determination of the Borrower) within eighteen (18) months after the Effective Date and (y) acquisitions, Dispositions, discontinuance of activities or operations or other Specified Transactions (including, for the avoidance of doubt, acquisitions occurring prior to the Effective Date), restructurings, cost savings initiatives, operational changes and other initiatives that are factually supportable and reasonably identified in writing to the Administrative Agent together with the delivery of a certificate pursuant to Section 9.1(c) and projected by the Borrower in good faith to result from (and are reasonably attributable to (in the good faith determination of the Borrower)) actions taken or committed to be taken or with respect to which substantial steps have been taken or are expected to be taken (in the good faith determination of the Borrower) no later than eighteen (18) months after such acquisition, Disposition or other Specified Transaction, restructuring, cost savings initiative, operational change or other initiative (or undertaken or implemented prior to consummation of the acquisition or other applicable transaction) (including any actions taken on or prior to the Effective Date), in each case for foregoing clauses (x) and (y), calculated on a Pro Forma Basis as though such cost savings, operating expense reductions and synergies had been realized on the first day of the period for which Consolidated EBITDAX is being determined and if such cost savings, operating expense reductions and synergies were realized during the entirety of such period, net of the amount of actual benefits realized during such period from such action (it is understood and agreed that “run rate” means the full recurring benefit for a period that is associated with

any action taken or with respect to which substantial steps have been taken or are expected to be taken or committed to be taken within the timeframe described above) (which adjustments may be incremental to (but not duplicative of) pro forma cost savings, synergies or operating expense reduction adjustments made pursuant to Section 1.12); provided further that the aggregate amount of any such “run rate” net cost savings, synergies and operating expense reductions add-backs made pursuant to this clause (vii) and clause (c) of Section 1.12 shall not exceed 15% of Consolidated EBITDAX (calculated prior to giving effect to such add-backs), plus”
