obligations other than those expressly provided for in the Loan Documents; and 
 (e) subject to Section 9.02 of the 2011
Credit Agreement, as incorporated herein by reference, to execute, deliver and accept on behalf of the Lenders the Loan Documents.

analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and
information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or
thereunder. 
 SECTION 5.04 Indemnification. The Lenders agree to indemnify the Administrative Agent (to the
extent not reimbursed by the Borrower), ratably according to their respective Applicable Percentages, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of
any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Administrative Agent in any way relating to or arising out of this Agreement or the other Loan Documents or any action taken or omitted by the Administrative
Agent under this Agreement or the other Loan Documents, provided, that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from such Person’s gross negligence or willful misconduct. IT IS THE EXPRESS INTENTION OF THE PARTIES HERETO THAT THE ADMINISTRATIVE AGENT SHALL BE INDEMNIFIED AND HELD HARMLESS AGAINST ANY AND ALL







 
LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS OF ANY KIND ARISING OUT OF OR RESULTING FROM THE ORDINARY NEGLIGENCE (WHETHER
SOLE OR CONTRIBUTORY) OR STRICT LIABILITY OF THE ADMINISTRATIVE AGENT. The Administrative Agent shall not be required to do any act hereunder or under any other document or instrument delivered hereunder or in connection herewith or take any action
toward the execution or enforcement of the agencies hereby created, or to prosecute or defend any suit in respect of this Agreement or the Loan Documents or any collateral security, unless indemnified to its satisfaction by the Lenders against loss,
cost, liability, and expense. If any indemnity furnished to the Administrative Agent for any purpose is, in the opinion of the Administrative Agent insufficient or becomes impaired, the Administrative Agent may call for additional indemnity and not
commence or cease to do the acts indemnified against until such additional indemnity is furnished. Without limitation of the foregoing, each Lender agrees to reimburse the Administrative Agent promptly upon demand for its ratable share of any
out-of-pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or
otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement and the other Loan Documents, to the extent that the Administrative Agent is not reimbursed for such expenses by the Borrower.
