Loans made on the Eleventh Amendment Effective Date (collectively, the “Cash-Capped Incremental Facility”) plus an unlimited amount that could be incurred while at the same time remaining in compliance with the Senior
Incurrence Test on a pro forma basis (the “Senior Incurrence Incremental Facility”), provided that any New Loan Commitments established pursuant to this Section 2.25(a) (other than New Loan Commitments established on the
Eleventh Amendment Effective Date) (i) will count towards the Senior Incurrence Incremental Facility (to the extent permitted by the pro forma calculation of the Senior Incurrence Test required prior to the incurrence of such Senior Incurrence
Incremental Facility) prior to reducing the maximum amount under the Cash-Capped Incremental Facility and (ii) may be incurred under the Cash-Capped Incremental Facility and the Senior Incurrence Incremental Facility, and proceeds from any such
incurrence may be utilized in a single transaction by first calculating the incurrence under the Senior Incurrence Incremental Facility (without inclusion of any amounts utilized pursuant to the Cash-Capped Incremental Facility) and then calculating
the incurrence under the Cash-Capped Incremental Facility. Each such notice shall specify the date (each, an “Increased Amount Date”) on which the Borrower proposes that the New Loan Commitments shall be effective, which shall be a
date not less than 5 Business Days (or such shorter period as the Administrative Agent may agree in its reasonable discretion) after the date on which such notice is delivered to Administrative Agent; provided that any Lender offered or
approached to provide all or a portion of any New Loan Commitments may elect or decline, in its sole discretion, to provide such New Loan Commitment; provided that, at the request of the Borrower, the Joint Lead Arrangers (in consultation
with the Borrower), will use their commercially reasonable efforts to obtain financial institutions (reasonably satisfactory to the Borrower) to provide a commitment to the extent necessary to satisfy the Borrower’s request for New Loans
subject to prevailing market conditions and payment of customary fees. Such New Loan Commitments shall become effective as of such Increased Amount Date; provided that (1) no Event of Default shall exist on such Increased Amount Date
before or after giving effect to such New Loan Commitments and to the making of any tranche of New Loans pursuant thereto and after giving effect to any Permitted Acquisition consummated in accordance therewith; (2) the proceeds of any New
Loans shall be used for general corporate purposes of the Borrower and its Subsidiaries (including Permitted Acquisitions); (3) the New Loans shall share ratably in the Collateral; (4) the New Loans that are term loans (“New Term
Loans”) shall share ratably in any mandatory prepayments of the existing Term Loans; (5) in the case of any New Term Loans, the maturity date thereof shall not be earlier than the latest maturity date of any Term Loan Tranche and the
weighted average life to maturity shall be equal to or greater than the weighted average life to maturity of the Term Loans that are not New Loans; (6) in the case of any New Loans that are revolving loans (“New Revolving
Loans”) the maturity date thereof shall be the then latest maturity date of any Revolving Tranche and such New Revolving Loans shall not require any scheduled commitment reductions prior to such maturity date; (7) the New Revolving
Loans shall share ratably in any mandatory prepayments of the existing Revolving Loans; (8) all terms and documentation with respect to any New Loans which differ from those with respect to the Loans under the applicable Facility shall be
reasonably satisfactory to the Administrative Agent; (9) such New Loan Commitments shall be effected pursuant to one or more Joinder Agreements executed and delivered by the Borrower, the Administrative Agent and one or more New Lenders; and
(10) the Borrower shall deliver or cause to be delivered any customary legal opinions or other documents reasonably requested by the Administrative Agent in connection with any such transaction, including any supplements or amendments to the

	ENDORSEMENT MANUAL – Fidelity National Title Group, Inc.		SECTION 11

 ENDORSEMENT 

Attached to Policy No.              

Issued By 
 [FNTG BRAND]

 The Company insures against loss or damage sustained by the Insured by reason of: 

 

	 	1.	The invalidity or unenforceability of the lien of the Insured Mortgage upon the Title at Date of Endorsement as a result of the agreement dated
                     recorded          (“Modification”); and 


 

	 	2.	The lack of priority of the lien of the Insured Mortgage, at Date of Endorsement, over defects in or liens or encumbrances on the Title, except for those shown in the policy or any prior endorsement and except: [ADD
EXCEPTIONS HERE] 

 This endorsement does not insure against loss or damage, and the Company will not pay costs, attorneys’ fees, or
expenses, by reason of any claim that arises out of the transaction creating the Modification by reason of the operation of federal bankruptcy, state insolvency, or similar creditors’ rights laws that is based on: 

 

	 	1.	the Modification being deemed a fraudulent conveyance or fraudulent transfer; or 

  

	 	2.	the Modification being deemed a preferential transfer except where the preferential transfer results from the failure 

  

	 	a.	to timely record the instrument of transfer; or 

  

	 	b.	of such recordation to impart notice to a purchaser for value or to a judgment or lien creditor. 

 This
endorsement is issued as part of the policy. Except as it expressly states, it does not (i) modify any of the terms and provisions of the policy, (ii) modify any prior endorsements, (iii) extend the Date of Policy, or
(iv) increase the Amount of Insurance. To the extent a provision of the policy or a previous endorsement is inconsistent with an express provision of this endorsement, this endorsement controls. Otherwise, this endorsement is subject to all of
the terms and provisions of the policy and of any prior endorsements.
