WHEREAS, reference is made to that certain $200,000,000 Second Amended and Restated Multicurrency Master Note Purchase Agreement, dated as of

Holders its (a) 3.42% Series 2017-A Senior Notes due June 16, 2027 in the original aggregate principal amount of $50,000,000 (as in effect immediately prior to giving effect to this Amendment, the

WHEREAS, the Company, MetLife and the Holders are willing to enter into such amendments and to amend and restate the Existing Notes subject
and pursuant to the terms and conditions of this Amendment; 
 NOW, THEREFORE, in consideration of the premises and mutual covenants
contained herein, the parties hereto agree as follows:

of the First Amendment Effective Date, the Note Facility is hereby amended as follows: 
 (a)    Section
2.1 of the Note Facility is hereby amended and restated in its entirety as follows: 

2.1.    Facility. MetLife is willing to consider, in its sole discretion and within the
limits which may be authorized for purchase by MetLife Affiliates from time to time, the purchase of Shelf Notes pursuant to this Agreement. The willingness of MetLife to consider such purchase of Shelf Notes is herein called the
“Facility”. At any time the aggregate principal amount of Shelf Notes in Section 1.4, minus the aggregate principal amount of Shelf Notes purchased and sold pursuant to this Agreement and outstanding at such time, minus the
aggregate principal amount of Accepted Notes (as hereinafter defined) which have not yet been purchased and sold hereunder prior to such time, is herein called the “Available Facility Amount” at such time. For the purposes of the
preceding sentence, all aggregate principal amounts of Shelf Notes and Accepted Notes shall be calculated in Dollars; with respect to any Shelf Notes denominated or Accepted Notes to be denominated in any Available Currency other than Dollars, the
Dollar Equivalent of Shelf Notes or Accepted Notes shall be used for such calculation. For the avoidance of doubt, the Available Facility Amount shall be increased by the principal amount of any outstanding Shelf Notes which are repaid or prepaid
prior to the expiration of the Issuance Period (but in no event shall the Available Facility Amount exceed $100,000,000 at any time). NOTWITHSTANDING THE WILLINGNESS OF METLIFE TO CONSIDER PURCHASES OF SHELF NOTES BY METLIFE AFFILIATES, THIS
AGREEMENT IS ENTERED INTO ON THE EXPRESS UNDERSTANDING THAT NEITHER METLIFE NOR ANY METLIFE AFFILIATE SHALL BE OBLIGATED TO MAKE OR ACCEPT OFFERS TO PURCHASE SHELF NOTES, OR TO QUOTE RATES, SPREADS OR OTHER TERMS WITH RESPECT TO SPECIFIC PURCHASE OF
SHELF NOTES, AND THE FACILITY SHALL IN NO WAY BE CONSTRUED AS A COMMITMENT BY METLIFE OR ANY METLIFE AFFILIATE. 

(b)    Subsection 2.2(i) of the Note Facility is hereby amended and restated in its entirety as follows:

or warranty applicable to any particular Closing Day shall change or otherwise modify or be deemed or construed to change or otherwise modify any representation or warranty given on any other Closing Day or any determination of the falseness or
inaccuracy thereof pursuant to Section 11(e) and (ii) no supplement to Section 5.3 or Schedule 5.3 as to any particular Closing Day shall be made after the Company makes a Request for Purchase in respect of such Closing Day.

 This Agreement and the documents, certificates or other writings
(including the financial statements described in Section 5.5 and the financial statements provided pursuant to the terms hereof) delivered to the Purchasers by or on behalf of the Company in connection with the transactions contemplated hereby
(this Agreement and such documents, certificates or other writings and financial statements delivered to each Purchaser prior to the applicable Closing Day being referred to, collectively, as the “Disclosure Documents”), taken as a
whole, do not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading in light of the circumstances under which they were made. Except as disclosed in the Disclosure
Documents, since the end of the most recent fiscal year for which audited financial statements have been furnished there has been no change in the financial condition, operations, business or properties of the Company or any Subsidiary except
changes that individually or in the aggregate could not reasonably be expected to have a Material Adverse Effect. There is no fact known to the Company that could reasonably be expected to have a Material Adverse Effect that has not been set forth
herein or in the Disclosure Documents. For the purposes of this Section 5.3, the Disclosure Documents shall be deemed to include all filings made with, or furnished to, the Securities and Exchange Commission by the Company pursuant to sections
13 or 15(d) of the Exchange Act, and the Company shall be deemed to have made delivery of any such Disclosure Document if it shall have timely made such Disclosure Document available on the Securities and Exchange Commission’s Electronic Data
Gathering Analysis, and Retrieval system, or its successor thereto (“EDGAR”). Notwithstanding the foregoing, for purposes of this Section 5.3, and only from the First Amendment Effective Date until December 31, 2020, the
impacts of the existing Coronavirus pandemic on the business, operations or financial condition of the Company and its Subsidiaries taken as a whole that have occurred and were disclosed in writing to MetLife prior to the First Amendment Effective
Date will be disregarded.

calculations of the maximum or minimum amount, ratio or percentage, as the case may be, permissible under the terms of such Sections, and the calculation of the amount, ratio or percentage then in existence), (iii) a reconciliation of the treatment
of leases which are or would be deemed by GAAP as in effect on the date hereof to be treated as operating leases, in form and substance reasonably satisfactory to the Required Holder and and (iv) with respect to the financial statements

connection with court proceedings in an aggregate amount not in excess of $10,000,000 (except to the extent covered by independent third-party insurance) provided that the execution or other enforcement of such Liens is effectively stayed and
the claims secured thereby are being actively contested in good faith and by appropriate proceedings; 

(g)    Subsection 10.9 of the Note Facility is hereby amended and restated in its entirety as follows: 

10.9.    Leverage Ratio. 

(a)    The Company will not (i) permit the Consolidated Leverage Ratio (as defined in this Agreement
as in effect prior to the First Amendment Effective Date) at any time during any period of four consecutive fiscal quarters of the Company (in each case taken as one accounting period) ending on or before March 31, 2020 to exceed 3.25 to 1.00,
(ii) permit the Consolidated Net Leverage Ratio at any time during any period of four consecutive fiscal quarters of the Company (in each case taken as one accounting period) ending after March 31, 2020 and on or before March 31, 2021 to
exceed 3.75 to 1.00 or (iii) permit the Consolidated Leverage Ratio at any time during any period of four consecutive fiscal quarters of the Company (in each case taken as one accounting period) ending after March 31, 2021 to exceed 3.25
to 1.00; provided, that, to the extent the Company consummates during any fiscal quarter of the Company ending after March 31, 2021 an acquisition permitted by this Agreement for aggregate cash consideration exceeding $150,000,000 (each,
a “Material Acquisition”), the Company may elect, upon written notice to MetLife and each holder of a Note, which notice shall be provided no later than the last Business Day of the fiscal quarter in which the relevant Material
Acquisition is consummated, to increase the maximum Consolidated Leverage Ratio permitted by this Section 10.9(a) to 3.75 to 1.00 for the fiscal quarter in which such Material Acquisition is consummated and the three consecutive fiscal quarters
of the Company following such Material Acquisition (each, a “Four Quarter Period”) (retroactive to the first day of such Four Quarter Period), and the interest rate applicable to the Notes (including, for the avoidance of doubt, the
Leverage Spike, if applicable) shall increase by 0.50% per annum during the period from the first day of the second fiscal quarter of the Company in such Four Quarter Period until the earlier of (i) the last day of such fiscal quarter at the
end of which the Consolidated Leverage Ratio for the four fiscal quarters of the Company then ended did not exceed 3.25 to 1.00 and (ii) the last day of the first fiscal quarter of the Company ending after such Four Quarter Period (each a
“Covenant Reset Date”) (such increase, the “Acquisition Spike”); provided further that, the maximum Consolidated Leverage Ratio may be increased to 3.75 to 1.00 for a Four Quarter Period in connection
with a Material Acquisition no more than three times after the Original Closing Date. For the avoidance of doubt, the Consolidated Leverage Ratio may not exceed 3.25 to 1.00 for the four fiscal quarters of the Company then last ended (in each case
taken as one accounting period) as of the last day of each fiscal quarter that ends after a Covenant Reset Date during a Four Quarter Period. If the Consolidated Leverage Ratio is increased for a Four Quarter Period pursuant to the preceding
sentence, no corresponding increase in the Consolidated Leverage Ratio with respect to a subsequent Material Acquisition may occur until the completion of at least one full fiscal quarter following the last day of such Four Quarter Period. 

  
 4 













 (b)    If, as of the last day of any four consecutive
fiscal quarters of the Company ending during the Leverage Spike Period, the Consolidated Net Leverage Ratio exceeds 3.00 to 1.00, as evidenced by a certificate of a Senior Financial Officer delivered pursuant to Section 7.2(a), the interest
rate applicable to the Notes shall be increased by 1.00% per annum (such increase, the “Leverage Spike”) for a period of time determined as follows: (A) such Leverage Spike shall begin to accrue on the first day of the fiscal
quarter following the fiscal quarter in which such certificate of a Senior Financial Officer was delivered and (B) shall continue to accrue until the Company has provided a certificate of a Senior Financial Officer pursuant to
Section 7.2(a) demonstrating that, (x) with respect to any four consecutive fiscal quarters of the Company ending after March 31, 2020 and before June 30, 2021, as of the last day of the four consecutive fiscal quarters of the
Company in respect of which such certificate is delivered, the Consolidated Net Leverage Ratio is not more than 3.00 to 1.00, or (y) with respect to any four consecutive fiscal quarters of the Company ending on or after June 30, 2021, as
of the last day of the four consecutive fiscal quarters of the Company in respect of which such certificate is delivered, the Consolidated Leverage Ratio is not more than 3.25 to 1.00, and in the event such certificate is delivered, the Leverage
Spike shall cease to accrue on the last day of the fiscal quarter in which such certificate is delivered. For the avoidance of doubt, (i) if certificate of a Senior Financial Officer is not delivered on the day it is due in accordance with
Section 7.2(a), then the Leverage Spike shall accrue and be determined as if the Consolidated Net Leverage Ratio exceeds 3.00 to 1.00 as of the last day of the four consecutive fiscal quarters of the Company in respect of which such certificate
was due and such Leverage Spike shall continue to accrue at such rate until the next date of determination for the following period. For the avoidance of doubt, if, as of the last day of the
four consecutive fiscal quarters of the Company ending on or after June 30, 2021, the Consolidated Leverage Ratio is not more than 3.25 to 1.00, the Leverage Spike shall not accrue with respect to such four consecutive fiscal quarters of the
Company ending on such date or any four consecutive quarters of the Company ending thereafter.

the Note Facility and, except as specifically amended herein, the Note Facility shall continue to be in full force and effect and is hereby in all respects ratified and confirmed. Any and all notices, requests, certificates and other instruments
executed and delivered after the execution and delivery of this Amendment may refer to the Note Facility without making specific reference to this Amendment, but nevertheless all such references shall include this Amendment unless the context
otherwise requires. 
 SECTION 7.    Expenses. Without prejudice to the provisions of Section 15
(Expenses, Etc.) of the Note Facility, whether or not the amendments set forth herein become effective, the Company agrees to pay or reimburse MetLife and the Holders for all of their reasonable and invoiced out-of-pocket costs and expenses incurred in connection with the development, preparation and execution of this Amendment and any other documents prepared in connection herewith or therewith, and the

the parties to be, and shall not be construed to be, a novation of the Note Facility or an accord and satisfaction in regard thereto. 

SECTION 10.    Financing Document. This Amendment shall constitute a “Financing Document” for all
purposes of the Note Facility and the other Financing Documents. 
 SECTION 11.    Amendments; Execution in
Counterparts; Electronic Execution. 
 (a)    This Amendment shall not constitute an amendment of any
other provision of the Note Facility not referred to herein and shall not be construed as a waiver or consent to any further or future action on the part of the Company that would require a waiver or consent of the Holders or MetLife. Except as
expressly amended hereby, the provisions of the Note Facility are and shall remain in full force and effect. 

(b)    This Amendment may be executed in any number of counterparts and by the different parties hereto on
separate counterparts, including by means of facsimile or electronic transmission, each of which when so executed and delivered shall be an original, but all of which shall together constitute one and the same instrument. 

(c)    Delivery of an executed counterpart of a signature page of this Amendment by telecopy, emailed pdf.
or any other electronic means that reproduces an image of the actual executed signature page shall be effective as delivery of a manually executed counterpart of this Amendment. The words “execution,” “signed,”
“signature,” “delivery,” and words of like import in or relating to any document to be signed in connection with this Amendment and the transactions contemplated hereby shall be deemed to include an electronic sound, symbol, or
process attached to, or associated with, a contract or other record and adopted by a Person with the intent to sign, authenticate or accept such contract or record (each an “Electronic Signature”), each of which shall be of the same
legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal
Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act; provided that nothing herein shall require
MetLife or the Holders to accept Electronic Signatures in any form or format without their prior written consent. Without limiting the generality of the foregoing, each party hereto hereby (i) agrees that, for all purposes, including without
limitation, in connection with any workout, restructuring, enforcement of remedies, bankruptcy proceedings or litigation among the MetLife, the Company and the other parties hereto, electronic images of this Amendment or any other Financing
Documents (in each case, including with respect to any signature pages thereto) shall have the same legal effect, validity and enforceability as any paper original, and (ii) waives any argument, defense or right to contest the validity or
enforceability of this Amendment or any of the other Financing Documents based solely on the lack of paper original copies of this Amendment or any other Financing Documents, including with respect to any signature pages hereto or thereto.

 SECTION 12.    Successors and Assigns. All covenants and
other agreements contained in this Amendment by or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and assigns (including, without limitation, any subsequent holder of a Note) whether so expressed
or not. 
 SECTION 13.    Severability. Any provision of this Amendment that is prohibited or unenforceable
in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to
the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction.
