			CONFIDENTIAL SEVERANCE AND RELEASE AGREEMENT
		

		
			 
		

		
			This Confidential Severance and Release Agreement (“Agreement”) is entered into by and between James Overholt (“Employee”) and Ministry Partners Investment Company LLC  (“MPIC” or the “Company”).  Employee and MPIC are collectively referred to as the Parties in this Agreement.
		

		
			RECITALS
		

		
			 
		

		
			Employee was hired by the Company on May 13, 2014.  He most recently held the position of President and Chief Executive Officer.  
		

		
			The Parties mutually agreed that Employee shall be resigning his position with the Company, with MPS, and with all other affiliated organization of the Company effective December 3, 2015.
		

		
			The Parties now enter into this Agreement to resolve any and all disputes arising out of or related to Employee’s employment, including all disputes that arise out of or relate to Employee’s separation from MPIC.
		

		
			AGREEMENT
		

		
			 
		

		
			In consideration of the covenants and promises in this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties agree as follows:
		

			
	
			
				 1.
			

			
	
			
			Resignation of Employment.

		
			a.Employee acknowledges and agrees that he resigned his employment with the Company, and has resigned from all positions he held with the Company, including any and all committees, from membership on the Board of Directors he held at the Company, effective December 3, 2015 (the “Separation Date”).  As of the Separation Date, Employee also has resigned from any and all positions, including any and all committees and from membership on the Board of Directors he held at MPS and from all other affiliate organizations of the Company.  
		

		
			b.The Company agrees, covenants, and represents that it will not oppose any application Employee may file or submit for unemployment insurance.  However, Employee agrees, covenants, and represents that he shall not, in any manner indicate in any application, form, or other document submitted in connection with obtaining unemployment compensation that: (1) his separation from the Company violated any law, including state or federal statute, rule or regulation or common law provision or was otherwise wrongful in any manner; or (2) that the Company violated any state or federal statute, rule, regulation, or common law provision, or otherwise engaged in any wrongful or unlawful conduct with respect to Employee’s employment.

				 2.
			

			
	
			
			Severance Benefits.

		
			Within a reasonable time after the Effective Date of this Agreement, and on the condition that Employee not exercise his/her right of revocation as provided in Section 3(d) of this Agreement, and on the further condition that Employee comply with the terms of this Agreement, the Company shall provide Employee with the following, which collectively will be referred to as the “Severance Benefits” in this Agreement:
		

		
			a.The Company will pay to Employee the total gross amount of $221,784.66 [Base Salary - $210,000.18, Medical $5,450.40 (Jim and Ila), Additional Benefits - $2,126.88,  2016 Medical Premiums $2,578.80 (Jim), 2016 Medical Expense $1,628.40 (Ila)] (the “Severance Payment”).  The Parties agree that the Severance Payment will be paid to Employee in one installments; however, at the Employee's one time option, the company may prepay any or all of the non-company provided insurance premiums directly to the provider. Employee agrees that the Company shall withhold from the Severance Payment and the related installment payments all applicable payroll taxes, as well as all other authorized or mandatory deductions. 
		

		
			b.Employee acknowledges that he is a Medicare recipient.  As part of the Severance Payment employee will be paid for his medical benefits; after December 3, 2015, Employee shall be solely responsible for paying any and all premiums necessary to continue such health insurance benefits.  Employee hereby acknowledges that he has received from the Company all required information and forms regarding his right to continue health insurance benefits under COBRA.
		

		
			c.Employee acknowledges and agrees that the Severance Benefits do not constitute money or benefits to which he is or may become entitled for any work performed for the Company through the Separation Date.  Employee further acknowledges and agrees that he is not eligible for, or entitled to, payment of any other benefits of employment, wages, bonuses, or commissions, except as provided in this Agreement. 
		

		
			d.If Employee breaches any term of this Agreement, he agrees that the Company will cease and desist from making any further, unpaid installment payments, and any installment payment previously paid by the Company to Employee shall be returned within 15 business days of such breach being established.
		

			
	
			
				 3.
			

			
	
			
			General Release And Covenant Not To Sue By Employee.

		
			a.Employee, for himself and his family, heirs, assigns, executors, administrators, and agents, past and present (collectively, the “Affiliates”), hereby fully and without limitation releases, covenants not to sue, and forever discharges MPIC, MPS, and their respective subsidiaries, affiliated entities, members, partners, directors, officers, shareholders, insurers, agents, employees, and predecessors and successors, past and present (collectively, the “Releasees”), both individually and collectively, from any and all rights, claims, demands, liabilities, actions, causes of action, suits, damages, losses, debts, attorney’s fees, costs, and expenses, of whatever nature whatsoever, known or unknown, fixed or contingent, suspected or unsuspected, that Employee or Affiliates now have, or may ever have had (“Claims”), against any of the Releasees arising out of, or related in any way to any of the following: (i) Employee’s 
		

		 

		

			2

		

		

			 

		

 

		employment with the Company, including the termination thereof; and (ii) any act, omission, or transaction of or by the Company or any of the Releasees occurring on or before the date the Employee executes this Agreement.
		

		
			b.Without limiting the foregoing, Employee understands and agrees that the foregoing release provisions waive and release Claims alleging violations of any federal or state employment discrimination law, including without limitation the California Fair Employment and Housing Act, Title VII of the Civil Rights Act of 1964; the Americans with Disabilities Act; the Age Discrimination in Employment Act (“ADEA”); Employee Retirement Income Security Act (ERISA); as well as Claims arising out of or related to violations of any other state or federal law, rule or regulation or any Claim arising out of any common law theory.
		

		
			c.  This Agreement, and the release contained herein, are subject to the terms of the Older Workers Benefit Protection Act of 1990 (the “OWBPA”).  The OWBPA provides that an individual cannot waive a right or claim under the ADEA unless the waiver is knowing and voluntary.  In compliance with OWBPA, Employee hereby acknowledges and agrees that he has executed this Agreement voluntarily, and with full knowledge of its consequences.  In addition, Employee hereby acknowledges and agrees as follows: (i) this Agreement has been written in a manner that is calculated to be understood, and it understood, by Employee; (ii) the release provisions of this Agreement apply to any rights Employee may have under the ADEA, including the right to file a lawsuit in state or federal court of age discrimination in violation of the ADEA; (iii) the release provisions of the Agreement do not apply to any rights or claims Employee may have under the ADEA that arise after Employee executes this Agreement; (iv) the Company does not have a preexisting duty to provide Employee with the Severance Benefits identified in this Agreement; (v) Employee has been advised and given the opportunity to consult with an attorney, and has consulted with an attorney to the extent he wished to do so, prior to executing this Agreement; (vi) Employee has had a period of at least 21 days to consider this Agreement; and (vii) Employee has the right to revoke this Agreement within seven days after its execution.  To revoke this Agreement, Employee must send written notice of his revocation of the Agreement to [ at fax number  or by email to ] within the time period noted above.  To the extent Employee revokes this Agreement, Employee agrees and acknowledge that he/she shall not be entitled to any of the Severance Benefits provided by this Agreement.
		

		
			d.Employee understands that by signing this Agreement and agreeing to the release of Claims, he is not waiving any right or claim that cannot be waived as a matter of law.  Employee further understands that the release of Claims does not prevent him from filing a charge with or participating in an investigation by a governmental administrative agency; provided, however, that Employee hereby waives any right to receive any monetary award resulting from such a charge or investigation.
		

			
	
			
				 4.
			

			
	
			
			Release Provisions Applicable To Unknown Claims.

		
			Employee further understands and acknowledges that he is aware of and familiar with the provisions of Section 1542 of the California Civil Code, which provides as follows:
		

		
			“A general release does not extend to claims which the creditor does not know or suspect to exist in his or her favor at the time of 
		

		 

		

			3

		

		

			 

		

 

		executing the release, which if known by him or her, must have materially affected his or her settlement with the debtor.”
		

		
			Notwithstanding such knowledge, Employee and the Affiliates hereby waive and relinquish all rights and benefits which they may have under Section 1542 of the California Civil Code and any other statute or common law principle to the same or similar effect.
		

			
	
			
				 5.
			

			
	
			
			General Release And Covenant Not To Sue By MPIC.

		
			MPIC, on its own behalf and, to the extent permitted by law, on behalf of its subsidiaries and affiliated entities, hereby fully and without limitation releases, covenants not to sue, and forever discharges Employee and his family, heirs, assigns, executors, administrators, and agents, past and present (collectively, the “Employee Releasees”) from any and all rights, claims, demands, liabilities, actions, causes of action, suits, damages, losses, debts, attorney’s fees, costs, and expenses, of whatever nature that MPIC, its subsidiaries and its affiliated entities have, or may ever have had against the Employee and any Employee Releasees arising out of, or related in any way to Employee’s employment with the Company.  Notwithstanding the generality of the foregoing, the Parties hereby agree that the covenant not to sue, discharge, and release of claims provided in this Section 5 shall not extend to any claims by MPIC, its subsidiaries or its related companies against Employee or the Employee Releasees involving currently unknown intentional or malicious misconduct arising out of or related to Employee’s employment, including claims involving embezzlement, fraud, or the intentional breach of fiduciary duties. 
		

			
	
			
				 6.
			

			
	
			
			Confirmation of Payment of Wages.

		
			Employee agrees and acknowledges that he has been paid all wages due and owing to him as of the Separation Date, including all accrued, but unused vacation pay, bonuses, commissions and payments of any other type for services rendered up to and including the Separation Date.
		

		
			 
		

			
	
			
				 7.
			

			
	
			
			Company Proprietary Information And Non-Solicitation.

		
			In consideration of the Severance Benefits and other promises provided by this Agreement, Employee agrees to the following terms.
		

		
			a.Non-Disclosure of Proprietary Information:  Employee understands and agrees that his work for the Company involved access to and creation of confidential, proprietary and trade secret information of the Company and of the Company’s subsidiaries (including MPS) and affiliates (collectively referred to and defined below as “Proprietary Information”).  Employee agrees to hold all such Proprietary Information and trade secrets in strict confidence and never to use or disclose any Proprietary Information or trade secrets to anyone at any time, except as specifically authorized in writing by an authorized officer of the Company.   Employee further understands and agrees that “Proprietary Information” for purposes of this Agreement means all information and any idea, whether disclosed to or learned or developed by Employee, pertaining in any manner to the business of the Company or to the Company’s affiliates (including subsidiaries), consultants, customers, and vendors, including any of the Company’s trade secrets, unless: (i) the information is or becomes publicly known through lawful means; (ii) the information was rightfully in my possession or part of my general knowledge prior; or 
		

		 

		

			4

		

		

			 

		

 

		(iii) the information is disclosed to Employee without confidential or proprietary restriction by a third party who rightfully possesses the information and did not learn of it, directly or indirectly, from the Company.  Employee understands that the Company considers the following information to be included, without limitation, in the definition of Proprietary Information:  (a) techniques, development tools and processes, computer printouts, computer programs, (b) information about loans, loan profiles, loan sales, costs, profits, revenues, margins and markets; (c) plans for future development and new product concepts; (d) customer names, addresses, telephone numbers, facsimile numbers, credit card numbers, contact persons and customer preferences; (e) vendor names, addresses, telephone numbers, facsimile numbers, contact persons, vendor preferences and pricing; (f) marketing plans, bidding information, costs of product, services and other items, proposal information, proposal methods and policies, price schedules, product profit margins, price setting methods and policies, customer service methods and policies and service plans and policies; (g) the Company’s business plans, audits and other non-public financial data related to the Company’s products and services.  Employee hereby confirms that he has returned to the Company all property belonging to the Company that came into his possession or control during his employment, including, without limitation, all equipment, keys, computer hardware and software, tangible proprietary information, documents, books, records, reports, contracts, lists, computer disks (or other computer-generated files or data), or copies thereof, created on any medium, prepared or obtained by him in the course of or incident to his employment with MPIC.
		

		
			b.Non-Solicitation:  Employee acknowledges and agrees that, because of his responsibilities at the Company, he helped to develop, and was exposed to, the Company’s business strategies, information on customers and clients, information about the Company’s employees, and other valuable Proprietary Information and trade secrets, and that use or disclosure of such Proprietary Information and trade secrets in breach of this Agreement would be extremely difficult to detect or prove.  Employee also acknowledges and agrees that the Company’s relationships with its employees, customers, clients, vendors, and other persons are valuable business assets.  Therefore, Employee agree as follows: (i) he shall not, for a period of one year following the Separation Date, directly or indirectly solicit, induce, recruit, or encourage any officer, director, or employee of the Company to leave the Company or terminate his employment with the Company; and (ii) he shall not use the Company’s Proprietary Information or trade secrets to interfere with any business relationship or contract between the Company and any of its customers, clients, vendors, business partners, or suppliers; or for the purpose of selling products or services competitive with the Company’s, solicit any person, firm, corporation or entity that was a customer or client or prospective client of the Company at any time during the one-year period preceding the Separation Date by using the Company’s Proprietary Information or trade secrets, or otherwise soliciting such customers by means that amount to unfair competition.  
		

			
	
			
				 8.
			

			
	
			
			Warranties; Representations and Non-Disparagement.

		
			a.Employee represents and warrants that he has not assigned or transferred any interest in any Claims that he has or may have against any of the Releasees.  Employee agrees to indemnify and hold the Releasees harmless from any liability, claims, demands, damages, expenses, and attorneys’ fees incurred as a result of any person or entity who successfully asserts such assignment or transfer.
		

		

		

		 

		

			5

		

		

			 

		

 

		b.Employee agrees not to disparage or defame MPIC, MPS, or any of their respective subsidiaries, directors, officers, employees or agents or its successors and assigns.  Employee acknowledges and understands that his obligations regarding non-disparagement extends to comments and statements made on social networking and blogging sites.  
		

		
			c.MPIC agrees that the current members of the Board of Directors and the Company’s managing agents, while employed by MPIC, shall not defame Employee regarding any aspect of his employment with MPIC or the performance of any of his duties on behalf of MPIC.
		

		
			 d.  Employee represents that he has not suffered any work-related injuries while employed by the Company and accordingly, he has not filed and does not intend to file any claim for workers’ compensation benefits of any type against the Company or MPS.  Employee acknowledges that the Company has relied upon these representations, and that the Company would not have entered into this Agreement but for these representations.  As a result, Employee agrees, covenants, and represents that the Company, or MPS if applicable, may, but is not obligated to, submit this Agreement to the Workers’ Compensation Appeals Board for approval as a full compromise and release as to any workers’ compensation claims in the event that Employee files such a claim.
		

			
	
			
				 9.
			

			
	
			
			Non-Admission of Liability.

		
			The Parties acknowledge and agree that this Agreement shall not be treated as an admission of liability or wrongdoing by any Party, at any time or for any purpose.
		

			
	
			
				 10.
			

			
	
			
			Confidentiality Of This Agreement.

		
			a.Except as may be required by law, Employee agrees, covenants, and represents that he has not and will not disclose, communicate, divulge, or discuss any facts relating to the negotiation, existence, or terms of this Agreement to any person, other than his immediate family and legal and financial advisors, without first obtaining the Company’s written consent to each disclosure.  
		

		
			b.MPIC agrees its managing agents will not divulge or discuss any facts relating to the negotiation, existence, or terms of this Agreement.  Notwithstanding the foregoing, the Parties agree that MPIC and its managing agents may disclose the facts relating to the negotiation, existence, and terms of this Agreement as necessary to effectuate its terms, to obtain legal or financial advice, to conduct business, to report as part of the Company’s corporate governance requirements, and to inform those individuals or businesses that MPIC determines in good faith have a need to know of this Agreement or its terms.
		

			
	
			
				 11.
			

			
	
			
			Successors and Assigns.

		
			This Agreement shall be binding upon and shall inure to the benefit of the Employee, MPIC, MPS and their respective heirs, executors, administrators, trustees, successors, assigns, affiliated entities, directors, officers, shareholders, partners, agents, and employees, past and present.

				 12.
			

			
	
			
			Integration; Modifications.

		
			a.This Agreement constitutes an integrated written contract expressing the entire agreement of the Parties with respect to the subject matter hereof, and supersedes and replaces all prior discussions, understandings, representations, promises, communications, and agreements, proposed or otherwise, whether written or oral, concerning the subject matter hereof.  There is no other agreement, written or oral, express or implied, between the Parties relating to the subject matter of this Agreement, other than this Agreement.  
		

		
			 
		

		
			b.This Agreement may not be modified orally.  It may be modified only by a written instrument that is signed by Employee and the MPIC’s Chairman of the Board.
		

			
	
			
				 13.
			

			
	
			
			Choice of Law.

		
			This Agreement shall be governed by and interpreted in accordance with the laws of the state of California without regard to California’s rules regarding conflicts of law.
		

			
	
			
				 14.
			

			
	
			
			Severability.

		
			Each and every provision of this Agreement shall be considered severable, except for the release provisions of Sections 3 and 4 of this Agreement.  If a court of competent jurisdiction holds that Sections 3 or 4 are illegal, invalid, or unenforceable, then this Agreement shall become null and void, and the Severance Benefits paid pursuant to Section 2 shall be returned to the Company within 15 days.  If any provision other than the provisions in Section 3 and 4 is declared illegal, invalid, or unenforceable for any reason, that provision shall remain in effect to the extent allowed by law, and all of the remaining provisions of this Agreement shall remain in full force and effect.

 Section 2.07. INTEREST PAYMENT AND
RECORD DATES. 
 The Interest Payment Dates for the Securities shall be February 15 and August 15
of each calendar year, beginning with, and including, August 15, 2016. The Regular Record Date for an Interest Payment Date that falls on February 15 shall be the immediately preceding February 1, and the Regular Record Date for an
Interest Payment Date that falls on August 15 shall be the immediately preceding August 1. 
 Section 2.08. NO

 Section 2.09. DEFAULTED INTEREST. 

If and to the extent the Company defaults in a payment of interest on the Securities, the Company shall pay in cash the defaulted interest in
any lawful manner plus, to the extent not prohibited by applicable statute or case law, interest on such defaulted interest at the rate provided in the Securities and in this Section 2.09. The Company may pay the defaulted interest (plus
interest on such defaulted interest) to the persons who are Securityholders on a subsequent record date as provided in Section 3.05(c) of the Base Indenture. 

The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal on the
Securities at the rate equal to 1% per annum in excess of the then applicable interest rate on the Securities of that series to the extent lawful; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy
Law) on overdue installments of interest (without regard to any applicable grace period) on the Securities of any series at the same rate to the extent lawful. 

Section 2.10. CUSIP AND ISIN NUMBERS. 

The Company in issuing the Securities may use one or more CUSIP and ISIN numbers, and, if so, the Trustee shall use the CUSIP and ISIN numbers
in notices of repurchase or exchange as a convenience to Holders; provided, however, that no representation is hereby deemed to be made by the Trustee as to the correctness or accuracy of the CUSIP and ISIN numbers printed on the
notice or on the Securities; provided further, that reliance may be placed only on the other identification numbers printed on the Securities, and the effectiveness of any such notice shall not be affected by any defect in, or omission of,
such CUSIP and ISIN numbers. The Company shall promptly notify the Trustee of any change in the CUSIP and ISIN numbers. 
 Section 2.11.
GLOBAL SECURITIES. 
 The Securities shall initially be issued in the form of one of more Global
Securities, and the provisions of the Base Indenture (including, but not limited to, Section 3.06 and Section 3.08) relating to Global Securities shall apply to the Securities. 

Section 2.12. RANKING. 

The indebtedness of the Company arising under or in connection with this Indenture and every outstanding Security issued under this Indenture
from time to time constitutes and will constitute a senior unsecured obligation of the Company, ranking pari passu in right of payment with each other and with all other existing and future senior unsecured obligations of the Company. Unless
the context otherwise requires, the 2021 Notes shall be considered collectively to be a single class for all purposes of this Indenture and the 2026 Notes shall be considered collectively to be a single class for all purposes of this Indenture,
including without limitation waivers, amendments, redemptions and Change of Control Offers. 
 Section 2.13. ADDITIONAL
SECURITIES. 
 The Company may, from time to time, subject to compliance with any other applicable provisions of this
Indenture, without the consent of the Holders, create and issue pursuant to this Indenture additional securities (“Additional Securities”) having terms and conditions identical to those of the Securities, except that Additional
Securities: 
 (i) may have a different issue date from the Securities; 

(ii) may have a different amount of interest payable on the first Interest Payment Date after issuance than is payable on other Securities;
and 
 (iii) may have terms specified in the Additional Securities Board Resolution or Additional Securities Supplemental Indenture for such
Additional Securities making appropriate adjustments to Article II and Exhibit A (and related definitions) applicable to such Additional Securities in order to conform to and ensure compliance with 

  
 12 

 
the Securities Act (or other applicable securities laws) and any other agreement applicable to such Additional Securities, which are not adverse in any material respect to the Holder of any
Securities (other than such Additional Securities); 
 provided, that no adjustment pursuant to this Section 2.13 shall cause
such Additional Securities to constitute, as determined pursuant to an Opinion of Counsel, a different class of securities than the Original Securities for U.S. federal income tax purposes. The Original Securities and any Additional Securities would
rank equally and ratably and would be treated as a single series of debt securities for all purposes under the Indenture. 
 ARTICLE III

(2) as determined by an Independent Investment Banker, the sum of the present values of the remaining scheduled payments of
principal and interest on the securities to be redeemed that would be due if such notes matured on the First Par Call Date (not including any portion of such payments of interest accrued to the date of redemption) discounted to the redemption date
on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate for such securities, plus 25 basis points; 

plus, in either of the above cases, accrued and unpaid interest to the date of redemption on the securities to be redeemed.

 13 

 plus, in either of the above cases, accrued and unpaid interest to the date of redemption on the securities to be

(e) If the optional redemption date is on or after a Regular Record Date and on or before the related Interest Payment Date, the accrued and

the Base Indenture. 
 Section 3.03. MANDATORY REDEMPTION. 

The Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Securities. 

ARTICLE IV COVENANTS 

Section 4.01. ADDITIONAL COVENANTS. 

In addition to those Covenants set forth in Article 4 of the Base Indenture, the Company shall comply with the following covenants: 

(a) Limitation on Liens. 

The Company shall not, and shall not permit any of its Subsidiaries to, allow any Lien on any of the Company’s or its Subsidiaries’
property or assets (which includes Capital Stock) securing Indebtedness, unless the Lien secures the Securities equally and ratably with, or prior to, any other Indebtedness secured by such Lien, so long as such other Indebtedness is so secured,
other than Permitted Liens. 
 Notwithstanding the foregoing, the Company may, and may permit any of its Subsidiaries to, incur Liens
securing Indebtedness without equally and ratably securing the Securities if, after giving effect to the incurrence of such Liens, the aggregate amount (without duplication) of the Indebtedness secured by Liens (other than Permitted Liens) on the
property or assets (which includes Capital Stock) of the Company and its Subsidiaries shall not exceed the Permitted Amount at the time of the incurrence of such Liens (it being understood that Liens securing SpectraSite ABS Facility shall be deemed
to be incurred pursuant to this paragraph). For the avoidance of doubt, “incur” means to create, incur, issue, assume, guarantee or otherwise become directly liable, contingently or otherwise. 

(b) Repurchase of the Securities Upon a Change of Control Triggering Event. 

Upon the occurrence of a Change of Control Triggering Event, each Holder of Securities shall have the right to require the Company to
repurchase all or any part, equal to $2,000 or an integral multiple of $1,000 thereafter, of that Holder’s Securities, provided that any unpurchased portion of the Securities shall equal $2,000 or an integral multiple of $1,000
thereafter, pursuant to an offer (the “Change of Control Offer”) on the terms set forth in this Indenture at an offer price in cash equal to 101% of the aggregate principal amount of Securities repurchased plus accrued and unpaid
interest on the Securities up to but excluding the applicable date of repurchase (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event, if the Company had not, prior to the Change of
Control Triggering Event, sent a redemption notice for all the Securities in connection with an optional redemption permitted by Section 3.02 hereof, the Company shall mail or caused to be mailed a notice to each registered Holder briefly
describing the transaction or transactions that constitute a Change of Control Triggering Event and offering to repurchase Securities on the date specified in such notice (the “Change 

  
 14 

 
of Control Payment Date”), which date shall be no earlier than 30 days and no later than 60 days from the date the notice is mailed, pursuant to the procedures required by this
Indenture and described in such notice. 
 The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder to the extent such laws and regulations are applicable to any Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this
Section 4.01(b), the Company shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the provisions of this Section 4.01(b) by virtue of such conflict. 

On the Change of Control Payment Date, the Company shall, to the extent lawful: 

(1) accept for payment all Securities or portions thereof properly tendered pursuant to the Change of Control Offer; 

(2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Securities or portions
thereof properly tendered; and 
 (3) deliver or cause to be delivered to the Trustee the Securities so accepted together
with an Officers’ Certificate stating the aggregate principal amount of Securities or portions thereof being purchased by the Company. 

The Paying Agent will promptly mail to each registered Holder of Securities so tendered the Change of Control Payment for such Securities, and
the Trustee will promptly authenticate and mail (at the Company’s expense), or cause to be transferred by book entry, to each Holder a new Security equal in principal amount to any unpurchased portion of the Securities surrendered, if any;
provided that each such new Security shall be in a principal amount of $2,000 or an integral multiple of $1,000 thereafter. Any Security so accepted for payment shall cease to accrue interest on and after the Change of Control Payment Date.

 This Section 4.01(b) shall be applicable, except as described in this Section 4.01(b), regardless of whether or not any other
provisions of this Indenture are applicable. 
 Notwithstanding the foregoing, the Company shall not be required to make a Change of Control
Offer upon a Change of Control Triggering Event if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.01(b) applicable to a Change of Control
Offer made by the Company and purchases all Securities properly tendered and not withdrawn under the Change of Control Offer. 
 The Company
may make a Change of Control Offer in advance of a Change of Control Triggering Event, and conditional upon the occurrence of such Change of Control Triggering Event, if a definitive agreement is in place for the Change of Control Triggering Event
at the time of making the Change of Control Offer.

 [REVERSE OF SECURITY] 

AMERICAN TOWER CORPORATION 

3.300% Senior Notes due 2021 

(the “Securities”) 

1. Interest. American Tower Corporation, a Delaware corporation (the “Company”), promises to pay interest on the
principal amount of this Security at the rate per annum shown above. The Company will pay interest, payable semi-annually in arrears, on February 15 and August 15 of each year, with the first payment to be made on August 15,
2016. Interest on the Securities will accrue on the principal amount from, and including, the most recent date to which interest has been paid or provided for or, if no interest has been paid, from, and including, January 12, 2016, in each case
to, but excluding, the next Interest Payment Date or the Stated Maturity for the payment of principal on the Securities, as the case may be; provided that if there is no existing Default in the payment of interest, the Company shall pay
interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at a rate that is 1% per annum in excess of the rate then in effect; it shall pay
interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest
shall be computed on the basis of a 360-day year of twelve 30-day months. 
 2. Maturity. The Securities will mature on
February 15, 2021. 
 3. Method of Payment. Except as provided in the Indenture (as defined below), the Company
shall pay interest on the Securities to the persons who are Holders of record of Securities at the close of business on the Regular Record Date set forth on the face of this Security next preceding the applicable Interest Payment Date. Holders must
surrender Securities to a Paying Agent to collect the principal amount. The Company shall pay, in money of the United States that at the time of payment is legal tender for payment of public and private debts, all amounts due in cash with respect to
the Securities, which amounts shall be paid (A) in the case this Security is a Global Security, by wire transfer of immediately available funds to the account designated by the Depository for the Securities or its nominee; and (B) in the
case this Security is a Physical Security, by mailing a check to the address of the relevant Holder set forth in the Security Register for the Securities. The Company shall pay, in cash, interest on any overdue amount (including, to the extent
permitted by applicable law, overdue interest) at the rate borne by the Securities. 
 4. Paying Agent and Registrar.
Initially, U.S. Bank National Association (the “Trustee”) shall act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar upon prior written notice to the Trustee. The Company or any of its Subsidiaries
may act in any such capacity. 
 5. Indenture. The Company issued the Securities under an indenture dated as of May 23,
2013 (as amended, supplemented or otherwise modified from time to time prior to the date hereof, the “Base Indenture”) between the Company and the Trustee, as amended, supplemented or otherwise modified by the Supplemental Indenture
No. 4 (the “Supplemental Indenture”), dated as of January 12, 2016, between the Company and the Trustee (the Base Indenture, as amended, supplemented or otherwise modified by the Supplemental Indenture, the
“Indenture”). The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb) (the
“TIA”) as amended and in effect from time to time. The Securities are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of such terms. To the extent any provision of this Security
conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Securities are general unsecured senior obligations of the Company. The Original Securities are limited to $750,000,000
aggregate principal amount, except as otherwise provided in the Indenture (except for Securities issued in substitution for destroyed, mutilated, lost or stolen Securities). Subject to the conditions set forth in the Indenture and without the
consent of the Holders, the Company may issue Additional Securities. All Securities, including any 

  
 A-1-4 

 
Additional Securities, shall be treated as a single class of securities under the Indenture. Terms used herein without definition and that are defined in the Indenture have the meanings assigned
to them in the Indenture. 
 6. Optional Redemption. The Securities are redeemable at the Company’s election, in whole or
in part, at any time from time to time. If the Company redeems the Securities prior to the First Par Call Date, the Company will pay a redemption price equal to the greater of: 

(1) 100% of the principal amount of the Securities to be redeemed then outstanding; and 

(2) as determined by an Independent Investment Banker, the sum of the present values of the remaining scheduled payments of
principal and interest on the Securities to be redeemed that would be due if such Securities matured on the First Par Call Date (not including any portion of such payments of interest accrued to the date of redemption) discounted to the redemption
date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 25 basis points; 
 plus, in
either of the above cases, accrued and unpaid interest to the date of redemption on the Securities to be redeemed. 
 If the Company redeems
the Securities on or after the First Par Call Date, the Company will pay a redemption price equal to 100% of the principal amount of the Securities to be redeemed plus accrued interest to the redemption date. 

If the Company selects a redemption date that is on or after a Regular Record Date and on or before the related Interest Payment Date, the
accrued and unpaid interest, if any, shall be paid to the person in whose name the Security is registered at the close of business on such Regular Record Date. 

The Company shall mail or cause to be mailed a notice of redemption at least 30 days, but not more than 60 days, before the redemption date to
each Holder of the Securities to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Securities or a
satisfaction and discharge of the Indenture. Notices of redemption may not be conditional. 
 Unless the Company defaults in payment of the
redemption price, on and after the redemption date, interest shall cease to accrue on the Securities or portions thereof called for redemption. Securities called for redemption become due on the date fixed for redemption. 

For purposes of the foregoing, the following terms have the following meanings: 

“Adjusted Treasury Rate” means, with respect to any redemption date: 

(1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most
recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States
Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (as defined below) (if no maturity is within three months before or after
the Remaining Life (as defined below), yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a
straight line basis, rounding to the nearest month); or 
 (2) if such release (or any successor release) is not published
during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable Treasury Price (as defined below) for such redemption date. 

  
 A-1-5 

 The Adjusted Treasury Rate shall be calculated on the third Business Day preceding the redemption
date. 
 “Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker
(as defined below) as having a maturity comparable to the remaining term of the Securities, calculated as if the maturity date of such Securities were the First Par Call Date (the “Remaining Life”), that would be utilized, at the
time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the Remaining Life of the Securities. 

“Comparable Treasury Price” means, for any redemption date, (1) the average of four Reference Treasury Dealer Quotations
(as defined below) for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average
of all such quotations. 
 “First Par Call Date” means January 15, 2021. 

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company. 

“Reference Treasury Dealer” means any of the primary U.S. Government securities dealers in New York City. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the
average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker at
5:00 p.m., New York City time, on the third Business Day preceding such redemption date. 
 7. No Mandatory Redemption.
The Company shall not be required to make mandatory redemption payments with respect to the Securities. 
 8. Repurchase
at Option of Holder. Upon the occurrence of a Change of Control Triggering Event, and subject to certain conditions set forth in the Indenture, the Company shall be required to offer to purchase all of the outstanding Securities at a purchase
price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, thereon to the date of repurchase. 

9. Notice of Redemption. Notice of redemption shall be mailed at least 30 days but not more than 60 days before the redemption
date to each Holder whose Securities are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with Article 10 or Article 11 of the
Base Indenture. Securities in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Securities held by a Holder are to be redeemed. Unless the Company defaults in payment of the redemption
price, on and after the redemption date interest shall cease to accrue on Securities or portions thereof called for redemption. 

10. Denominations, Transfer, Exchange. The Securities are in registered form, without coupons, in denominations of $2,000
principal amount and integral multiples of $1,000 principal amount. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or similar governmental charge that may be
imposed in connection with certain transfers or exchanges. The Company shall not be required to register the transfer of or exchange any Security selected for redemption, except for the unredeemed portion of any Security being redeemed in part.
Also, the Company need not exchange or register the transfer of any Securities for a period of 15 days next preceding the first mailing of notice of redemption of Securities to be redeemed. 

  
 A-1-6 

 11. Persons Deemed Owners. The registered Holder of a Security shall be
treated as the owner of such Security for all purposes. 
 12. Merger or Consolidation. The Company shall not
consolidate with or merge with or into, or sell, transfer, lease, convey or otherwise dispose of all or substantially all of its property or assets to, another Person (including pursuant to a statutory arrangement), whether in a single transaction
or series of related transactions, unless it complies with Article 8 of the Base Indenture. 
 13. Amendments,
Supplements and Waivers. The Indenture or the Securities may be amended or supplemented as provided in the Indenture. 

14. Defaults and Remedies. The Events of Default relating to the Securities are defined in Section 5.01 of the Base
Indenture. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Securities may declare the principal, premium, if any, interest and any other monetary obligations on
all the then outstanding Securities to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Securities shall become due and payable
immediately without further action or notice. 
 Holders may not enforce the Indenture or the Securities except as provided in the
Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Securities
notice of any continuing Default (except a Default relating to the payment of principal, premium, if any, or interest) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the
Securities then outstanding by notice to the Trustee may on behalf of the Holders of all of the Securities waive any existing Default and its consequences under the Indenture except a continuing Default in payment of the principal of, premium, if
any, or interest, if any, on, any of the Securities held by a non-consenting Holder. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required upon becoming aware of
any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default. 

15. Trustee Dealings with the Company. The Trustee, in its individual or any other capacity, may make loans to, accept
deposits from, and perform services for the Company or its affiliates, and may otherwise deal with the Company or its affiliates, as if it were not the Trustee. 

16. No Recourse Against Others. A director, officer, employee, incorporator or stockholder, of the Company, as such, shall
not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Security waives and releases
all such liability. The waiver and release are part of the consideration for the issuance of the Securities. 

17. Authentication. This Security shall not be valid until authenticated by the manual signature of the Trustee or an
authenticating agent in accordance with the Indenture. 
 18. Abbreviations. Customary abbreviations may be used
in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act). 
 19. CUSIP and ISIN Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security
Identification Procedures, the Company has caused CUSIP and ISIN numbers to be printed on the Securities and the Trustee may use CUSIP and ISIN numbers in notices of redemption as a convenience to Holders. No representation is made as to the

 [REVERSE OF SECURITY] 

AMERICAN TOWER CORPORATION 

4.400% Senior Notes due 2026 

(the “Securities”) 

1. Interest. American Tower Corporation, a Delaware corporation (the “Company”), promises to pay interest on the
principal amount of this Security at the rate per annum shown above. The Company will pay interest, payable semi-annually in arrears, on February 15 and August 15 of each year, with the first payment to be made on August 15,
2016. Interest on the Securities will accrue on the principal amount from, and including, the most recent date to which interest has been paid or provided for or, if no interest has been paid, from, and including, January 12, 2016, in each case
to, but excluding, the next Interest Payment Date or the Stated Maturity for the payment of principal on the Securities, as the case may be; provided that if there is no existing Default in the payment of interest, the Company shall pay
interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at a rate that is 1% per annum in excess of the rate then in effect; it shall pay
interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest
shall be computed on the basis of a 360-day year of twelve 30-day months. 
 2. Maturity. The Securities will mature on
February 15, 2026. 
 3. Method of Payment. Except as provided in the Indenture (as defined below), the Company
shall pay interest on the Securities to the persons who are Holders of record of Securities at the close of business on the Regular Record Date set forth on the face of this Security next preceding the applicable Interest Payment Date. Holders must
surrender Securities to a Paying Agent to collect the principal amount. The Company shall pay, in money of the United States that at the time of payment is legal tender for payment of public and private debts, all amounts due in cash with respect to
the Securities, which amounts shall be paid (A) in the case this Security is a Global Security, by wire transfer of immediately available funds to the account designated by the Depository for the Securities or its nominee; and (B) in the
case this Security is a Physical Security, by mailing a check to the address of the relevant Holder set forth in the Security Register for the Securities. The Company shall pay, in cash, interest on any overdue amount (including, to the extent
permitted by applicable law, overdue interest) at the rate borne by the Securities. 
 4. Paying Agent and Registrar.
Initially, U.S. Bank National Association (the “Trustee”) shall act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar upon prior written notice to the Trustee. The Company or any of its Subsidiaries
may act in any such capacity. 
 5. Indenture. The Company issued the Securities under an indenture dated as of May 23,
2013 (as amended, supplemented or otherwise modified from time to time prior to the date hereof, the “Base Indenture”) between the Company and the Trustee, as amended, supplemented or otherwise modified by the Supplemental Indenture
No. 4 (the “Supplemental Indenture”), dated as of January 12, 2016, between the Company and the Trustee (the Base Indenture, as amended, supplemented or otherwise modified by the Supplemental Indenture, the
“Indenture”). The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb) (the
“TIA”) as amended and in effect from time to time. The Securities are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of such terms. To the extent any provision of this Security
conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Securities are general unsecured senior obligations of the Company. The Original Securities are limited to $500,000,000
aggregate principal amount, except as otherwise provided in the Indenture (except for Securities issued in substitution for destroyed, mutilated, lost or stolen Securities). Subject to the conditions set forth in the Indenture and without the
consent of the Holders, the Company may issue Additional Securities. All Securities, including any 

  
 A-2-4 

 
Additional Securities, shall be treated as a single class of securities under the Indenture. Terms used herein without definition and that are defined in the Indenture have the meanings assigned
to them in the Indenture. 
 6. Optional Redemption. The Securities are redeemable at the Company’s election, in
whole or in part, at any time from time to time. If the Company redeems the Securities prior to the First Par Call Date, the Company will pay a redemption price equal to the greater of: 

(1) 100% of the principal amount of the Securities to be redeemed then outstanding; and 

(2) as determined by an Independent Investment Banker, the sum of the present values of the remaining scheduled payments of principal and
interest on the Securities to be redeemed that would be due if such Securities matured on the First Par Call Date (not including any portion of such payments of interest accrued to the date of redemption) discounted to the redemption date on a
semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 35 basis points; 
 plus, in either of the
above cases, accrued and unpaid interest to the date of redemption on the Securities to be redeemed. 
 If the Company redeems the
Securities on or after the First Par Call Date, the Company will pay a redemption price equal to 100% of the principal amount of the Securities to be redeemed plus accrued interest to the redemption date. 

If the Company selects a redemption date that is on or after a Regular Record Date and on or before the related Interest Payment Date, the
accrued and unpaid interest, if any, shall be paid to the person in whose name the Security is registered at the close of business on such Regular Record Date. 

The Company shall mail or cause to be mailed a notice of redemption at least 30 days, but not more than 60 days, before the redemption date to
each Holder of the Securities to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Securities or a
satisfaction and discharge of the Indenture. Notices of redemption may not be conditional. 
 Unless the Company defaults in payment of the
redemption price, on and after the redemption date, interest shall cease to accrue on the Securities or portions thereof called for redemption. Securities called for redemption become due on the date fixed for redemption. 

For purposes of the foregoing, the following terms have the following meanings: 

“Adjusted Treasury Rate” means, with respect to any redemption date: 

(1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most
recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States
Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (as defined below) (if no maturity is within three months before or after
the Remaining Life (as defined below), yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a
straight line basis, rounding to the nearest month); or 
 (2) if such release (or any successor release) is not published
during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable Treasury Price (as defined below) for such redemption date. 

The Adjusted Treasury Rate shall be calculated on the third Business Day preceding the redemption date. 

  
 A-2-5 

 “Comparable Treasury Issue” means the United States Treasury security selected
by an Independent Investment Banker (as defined below) as having a maturity comparable to the remaining term of the Securities, calculated as if the maturity date of such Securities were the First Par Call Date (the “Remaining
Life”), that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the Remaining Life of the Securities . 

“Comparable Treasury Price” means, for any redemption date, (1) the average of four Reference Treasury Dealer Quotations
(as defined below) for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average
of all such quotations. 
 “Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the
Company. 
 “First Par Call Date” means November 15, 2025. 

“Reference Treasury Dealer” means any of the primary U.S. Government securities dealers in New York City. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the
average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker at
5:00 p.m., New York City time, on the third Business Day preceding such redemption date. 
 7. No Mandatory Redemption.
The Company shall not be required to make mandatory redemption payments with respect to the Securities. 
 8. Repurchase
at Option of Holder. Upon the occurrence of a Change of Control Triggering Event, and subject to certain conditions set forth in the Indenture, the Company shall be required to offer to purchase all of the outstanding Securities at a purchase
price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, thereon to the date of repurchase. 

9. Notice of Redemption. Notice of redemption shall be mailed at least 30 days but not more than 60 days before the redemption
date to each Holder whose Securities are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with Article 10 or Article 11 of the
Base Indenture. Securities in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Securities held by a Holder are to be redeemed. Unless the Company defaults in payment of the redemption
price, on and after the redemption date interest shall cease to accrue on Securities or portions thereof called for redemption. 

10. Denominations, Transfer, Exchange. The Securities are in registered form, without coupons, in denominations of $2,000
principal amount and integral multiples of $1,000 principal amount. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or similar governmental charge that may be
imposed in connection with certain transfers or exchanges. The Company shall not be required to register the transfer of or exchange any Security selected for redemption, except for the unredeemed portion of any Security being redeemed in part.
Also, the Company need not exchange or register the transfer of any Securities for a period of 15 days next preceding the first mailing of notice of redemption of Securities to be redeemed. 

  
 A-2-6 

 11. Persons Deemed Owners. The registered Holder of a Security shall be
treated as the owner of such Security for all purposes. 
 12. Merger or Consolidation. The Company shall not
consolidate with or merge with or into, or sell, transfer, lease, convey or otherwise dispose of all or substantially all of its property or assets to, another Person (including pursuant to a statutory arrangement), whether in a single transaction
or series of related transactions, unless it complies with Article 8 of the Base Indenture. 
 13. Amendments,
Supplements and Waivers. The Indenture or the Securities may be amended or supplemented as provided in the Indenture. 

14. Defaults and Remedies. The Events of Default relating to the Securities are defined in Section 5.01 of the Base
Indenture. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Securities may declare the principal, premium, if any, interest and any other monetary obligations on
all the then outstanding Securities to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Securities shall become due and payable
immediately without further action or notice. 
 Holders may not enforce the Indenture or the Securities except as provided in the
Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Securities
notice of any continuing Default (except a Default relating to the payment of principal, premium, if any, or interest) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the
Securities then outstanding by notice to the Trustee may on behalf of the Holders of all of the Securities waive any existing Default and its consequences under the Indenture except a continuing Default in payment of the principal of, premium, if
any, or interest, if any, on, any of the Securities held by a non-consenting Holder. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required upon becoming aware of
any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default. 

15. Trustee Dealings with the Company. The Trustee, in its individual or any other capacity, may make loans to, accept
deposits from, and perform services for the Company or its affiliates, and may otherwise deal with the Company or its affiliates, as if it were not the Trustee. 

16. No Recourse Against Others. A director, officer, employee, incorporator or stockholder, of the Company, as such, shall
not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Security waives and releases
all such liability. The waiver and release are part of the consideration for the issuance of the Securities. 

17. Authentication. This Security shall not be valid until authenticated by the manual signature of the Trustee or an
authenticating agent in accordance with the Indenture. 
 18. Abbreviations. Customary abbreviations may be used
in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act). 
 19. CUSIP and ISIN Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security
Identification Procedures, the Company has caused CUSIP and ISIN numbers to be printed on the Securities and the Trustee may use CUSIP and ISIN numbers in notices of redemption as a convenience to Holders. No representation is made as to the
accuracy of such numbers either as printed on the Securities or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.
