Designation of Subsidiaries The Board of Directors of Holdings or the Borrower may at any time designate any Restricted Subsidiary of the Borrower as an Unrestricted Subsidiary or any Unrestricted Subsidiary as a Restricted Subsidiary by notice to the Agent; provided that, in each case, (i) other than with respect to any designation of Flotek or BPC as Unrestricted Subsidiaries after the Closing Date and only so long as Flotek or BPC are not Wholly Owned by Holdings, no Default or Event of Default is then continuing or would result therefrom, (ii) other than with respect to any designation of Flotek or BPC as Unrestricted Subsidiaries after the Closing Date and only so long as Flotek or BPC are not Wholly Owned by Holders, after giving effect to such designation the Aggregate Revolver Outstandings would not exceed the lesser of the Maximum Revolver Amount and the then-current Borrowing Base, (iii) no Restricted Subsidiary may be designated as an Unrestricted Subsidiary if it was previously designated as an Unrestricted Subsidiary and then re-designated as a Restricted Subsidiary, (iv) no Restricted Subsidiary may be designated as an Unrestricted Subsidiary if after such designation it would be a “restricted subsidiary” for the purpose of the Term Loan Credit Agreement or any other Material Indebtedness, (v) other than with respect to any designation of Flotek or BPC as Unrestricted Subsidiaries after the Closing Date and only so long as Flotek or BPC are not Wholly Owned by Holdings, the Borrower and the Restricted Subsidiaries shall be in compliance on a Pro Forma Basis with a Fixed Charge Coverage Ratio, as such ratio is calculated as of the last day of the Test Period most recently ended on or prior to the date of such designation, as if such designation and any related transactions had occurred on the first day of such Test Period, of not less than 1.00:1.00, and (vi) if such designation would result in Current Asset Collateral owned by a Borrower or Guarantor immediately prior to such designation being owned by an Unrestricted Subsidiary immediately after such designation with a value individually or in the aggregate of greater than 5.0% of the Borrowing Base based on the most recently delivered Borrowing Base Certificate prior to such event, then Borrower shall be required, prior to such designation, deliver to Agent an updated Borrowing Base Certificate that reflects the removal of the applicable assets from the Borrowing Base. The designation of any Restricted Subsidiary as an Unrestricted Subsidiary after the Closing Date shall constitute an Investment by the Borrower therein at the date of designation in an amount equal to the Fair Market Value of the Borrower’s investment therein and the Investment resulting from such designation must otherwise be in compliance with Section 8.11 (as determined at the time of such designation) (for the avoidance of doubt, the designation of Flotek and/or BPC as an Unrestricted Subsidiary shall not constitute an additional Investment thereof by any of the Obligors unless such designation occurs after Flotek and/or BPC (as applicable) become Wholly Owned Subsidiaries). The designation of any Unrestricted Subsidiary as a Restricted Subsidiary shall constitute the incurrence at the time of designation of any Debt or Liens of such Subsidiary existing at such time and the Debt or Liens of such Subsidiary must otherwise be in compliance with Section 8.12 and 8.16 (as determined at the time of such designation). Notwithstanding anything to the contrary contained herein, (x) no Unrestricted Subsidiary may at any time hold (directly or indirectly) Stock in, or Debt owed by or Liens (securing Debt for Borrowed Money) in, any Restricted Subsidiary and (y) in no event shall any Restricted Subsidiary that owns (or has an exclusive license to) any Intellectual Property that is material to the operations or the business of Holdings and its Restricted Subsidiaries be permitted to be designated as an Unrestricted Subsidiary, nor shall any Unrestricted Subsidiary be permitted to own (or have an exclusive license to), develop, or receive from Holdings or any of its Restricted Subsidiaries, any Intellectual Property that is material to the operations or the business of Holdings and its Restricted Subsidiaries.
