(b) Seller agrees to cooperate, including without limitation through the provision of information and filing of any tax returns, in connection with any election by the Company under Section 6226 of the Code (or corresponding provisions of state or local Tax Law). (c) The Parties shall cooperate (and cause their respective Affiliates to cooperate) fully, as and to the extent reasonably requested by the other Parties, in connection with the preparation and filing of tax returns of the Company and any tax audit, litigation or other proceeding with respect to taxes and payments in respect thereof. Such cooperation shall include the retention and (upon the other Parties’ request) the provision of records and information which are reasonably relevant to any such tax audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Each of the Parties shall furnish the other Parties with copies of all relevant correspondence received from any taxing authority in connection with any tax audit or information request with respect to any taxes for which any other Party may have any tax liability. 3.12 Transfer Tax. Buyer acknowledges and agrees that Buyer shall be responsible for any transfer tax (or similar tax) imposed that is associated with this Agreement or the transfer of the Membership Interest hereunder or any transfer tax (or similar tax) imposed that is associated with the entrance of Invesco to the A&R LLC Agreement, and Buyer shall indemnify, defend and hold Seller harmless from and against the payment of any of the foregoing transfer tax, including any penalties or fees in connection therewith. 3.13 Further Assurances.
