 SECTION 7. Amendment, Modification and Waiver. This First Lien Amendment No. 6 may not be
amended, modified or waived except in accordance with Section 10.01 of the First Lien Credit Agreement. 
 SECTION 8. Entire
Agreement; Post-Effective Date Obligations. This First Lien Amendment No. 6, the First Lien Credit Agreement, the Engagement Letter and the other Loan Documents constitute the entire agreement among the parties hereto with respect to
the subject matter hereof and thereof and supersede all other prior agreements and understandings, both written and verbal, among the parties hereto with respect to the subject matter hereof. Except as expressly set forth herein, this First Lien
Amendment No. 6 shall not by implication or otherwise limit, impair, constitute a waiver of, or otherwise affect the rights and remedies of any party under, the First Lien Credit Agreement, nor alter, modify, amend or in any way affect any of
the terms, conditions, obligations, covenants or agreements contained in the First Lien Credit Agreement, all of which are ratified and affirmed in all respects and shall continue in full force and effect. It is understood and agreed that each
reference in each Loan Document to the First Lien Credit Agreement, whether direct or indirect, shall hereafter be deemed to be a reference to the First Lien Credit Agreement as amended hereby and that this First Lien Amendment No. 6 is a Loan
Document. As promptly as practicable, and in any event within the time periods after the First Lien Amendment No. 6 Effective Date specified in Schedule B hereto or such later date as the Administrative Agent reasonably agrees to in
writing, including to reasonably accommodate circumstances unforeseen on the First Lien Amendment No. 6 Effective Date, deliver the documents or take the actions specified on Schedule B hereto, in each case except to the extent otherwise
agreed by the Administrative Agent pursuant to its authority as set forth in the definition of the term “Collateral and Guarantee Requirement”. 

SECTION 9. GOVERNING LAW. THIS FIRST LIEN AMENDMENT NO. 6 AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE
GOVERNED BY THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO ANY CONFLICT OF LAW PRINCIPLES (BUT GIVING EFFECT TO FEDERAL LAWS RELATING TO NATIONAL BANKS). THE PROVISIONS OF SECTIONS 10.16 AND 10.17 OF THE FIRST LIEN CREDIT AGREEMENT
ARE HEREBY INCORPORATED BY REFERENCE INTO THIS FIRST LIEN AMENDMENT NO. 6 AND SHALL APPLY HEREIN MUTATIS MUTANDIS. 

SECTION 10. Severability. If any provision of this First Lien Amendment No. 6 is held to be illegal, invalid or
unenforceable, the legality, validity and enforceability of the remaining provisions of this First Lien Amendment No. 6 shall not be affected or impaired thereby. The invalidity of a provision in a particular jurisdiction shall not invalidate
or render unenforceable such provision in any other jurisdiction. 
 SECTION 11. Counterparts. This First Lien Amendment No.
6 may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Delivery by facsimile or other electronic means of an

  
 9 

 
executed counterpart of a signature page to this First Lien Amendment No. 6 shall be effective as delivery of an original executed counterpart of this First Lien Amendment No. 6. 

SECTION 12. Headings. The headings of this First Lien Amendment No. 6 are for purposes of reference only and shall not
limit or otherwise affect the meaning hereof. 
 SECTION 13. Miscellaneous. The provisions of Sections 10.04, 10.05, 10.09 and
10.23 of the First Lien Credit Agreement are hereby incorporated by reference into this First Lien Amendment No. 6 and shall apply herein mutatis mutandis and, for the avoidance of doubt, any reference in such Sections to Arrangers shall

 AND
ITS SUBSIDIARIES 
 November 14, 2016 

Pursuant to that certain First Lien Amendment No. 6, dated as of the date hereof (the “First Lien Amendment
No. 6”), by and among DTZ UK Guarantor Limited, a limited company incorporated under the laws of England and Wales with company number 09187412 (“Holdings”), DTZ U.S. Borrower, LLC, a Delaware limited
liability company (the “U.S. Borrower”), DTZ AUS Holdco Pty Limited ACN 602 106 936, a proprietary company limited by shares incorporated under the laws of Australia (the “Australian Borrower” and, collectively with
the U.S. Borrower, the “Borrowers”), each of the other Loan Parties party thereto, the 2016-2 Incremental Term Lender and UBS AG, Stamford Branch as Administrative Agent, to the Syndicated

restated, refinanced, extended, supplemented and/or otherwise modified from time to time, the “First Lien Credit Agreement”), the undersigned hereby certifies, solely in such undersigned’s capacity as a Responsible Officer of
the Borrower Representative, and not individually, as follows: 
 As of the date hereof, after giving effect to the
borrowing of the 2016-2 Incremental Term Loans (as defined in First Lien Amendment No. 6) and to the application of the proceeds of such Loans: 

 

	 	a.	The fair value of the assets of Holdings and its Subsidiaries, on a consolidated basis, exceeds, on a consolidated basis, their debts and liabilities, subordinated, contingent or otherwise; 

 

	 	b.	The present fair saleable value of the property of Holdings and its Subsidiaries, on a consolidated basis, is greater than the amount that will be required to pay the probable liability, on a consolidated basis, of
their debts and other liabilities, subordinated, contingent or otherwise, as such debts and other liabilities become absolute and matured; 

  

	 	c.	Holdings and its Subsidiaries, on a consolidated basis, are able to pay their debts and liabilities, subordinated, contingent or otherwise, as such liabilities become absolute and matured; 

 

	 	d.	Holdings and its Subsidiaries, on a consolidated basis, are not engaged in, and are not about to engage in, business for which they have unreasonably small capital; and 

	 	e.	Each Loan Party incorporated in Australia is solvent for the purposes of the Australian Corporations Act 2001 (Cth). 

For the purposes of making the certifications set forth in this solvency certificate (this “Certificate”), it is assumed the
indebtedness and other obligations incurred under the First Lien Credit Agreement will come due at their respective maturities. For purposes of this Certificate, the amount of any contingent liability at any time shall be computed as the amount that
would reasonably be expected to become an actual and matured liability. Capitalized terms used but not otherwise defined herein shall have the meanings assigned to them in the First Lien Credit Agreement. 

The undersigned is familiar with the business and financial position of Holdings and its subsidiaries. In reaching the conclusions set forth
in this Certificate, the undersigned has made such other investigations and inquiries as the undersigned has deemed appropriate, having taken into account the nature of the particular business anticipated to be conducted by Holdings and its
subsidiaries after borrowing of the 2016-2 Incremental Term Loans. 

 IN WITNESS WHEREOF, the undersigned has executed this Certificate in such undersigned’s
capacity as [chief financial officer] [specify other officer with equivalent duties] of Holdings, on behalf of the Holdings, and not individually, as of the date first stated above.
