and agreed that, in connection with a Material Permitted Investment that is to be consummated in reliance on clause (j) of Section 6.6, an Adjusted Covenant Period shall be deemed to be in effect for purposes of testing Pro Forma compliance with this Section 6.7(a) as of the last day of the most recently ended Test Period ending prior to the applicable date of determination as required under clause (c) of the definition of “Permitted Acquisition” and under Section 1.5 (without such Test Period (or any subsequent Test Period ending prior to the Test Period in which such Material Permitted Investment is consummated) counting as one of the four consecutive Test Periods that would constitute the Adjusted Covenant Period for such Material Permitted Investment)) and (y) notwithstanding the foregoing clause (x), absent the consent of the Required Lenders, (A) the Company may only make an election for an Adjusted Covenant Period with respect to any Material Permitted Investment on or prior to the date that the Company delivers the Compliance Certificate (and related financial statements required pursuant to section 5.1(a) or 5.1(b), as applicable) covering the Fiscal Quarter in which the Material Permitted Investment was consummated and (B) the Company may not elect an Adjusted Covenant Period for at least one full Fiscal Quarter following the end of an Adjusted Covenant Period (it being understood and agreed, for the avoidance of doubt, that notwithstanding any actual election for an Adjusted Covenant Period (or any Adjusted Covenant Period being deemed to be in effect pursuant to the parenthetical at the end of the preceding clause (x)), the Company shall be deemed not to have elected an Adjusted Covenant Period if the applicable Material Permitted Investment is not consummated); provided, further, that (i) the Company will provide notice in writing to the Administrative Agent of such increase and a transaction description of such Material Permitted Investment (regarding the name of the Person or assets being acquired and the approximate purchase price, subject in each case to applicable confidentiality restrictions) and (ii) following the completion of each Adjusted Covenant Period, the maximum Total Net Leverage Ratio permitted under this Section 6.7(a) will revert to 4.00 to 1.00.

For any Test Period ending on or after the 2022 Acquisition Closing Date, the Company will not permit the Total Net Leverage Ratio on the last day of each such Test Period ending as of the last day of the Fiscal Quarter for which financial statements have been or are required to have been delivered pursuant to Section 5.1(b) to be greater than (x) 5.00 to 1.00 for each Test Period ending on or after the 2022 Acquisition Closing Date, but on or prior to the first anniversary of the 2022 Acquisition Closing Date, (y) 4.75 to 1.00 for each Test Period ending after the first anniversary, but on or prior to the second anniversary of the 2022 Acquisition Closing Date and (z) 4.50 to 1.00 for each Test Period ending after the second anniversary of the 2022 Acquisition Closing Date.
