Description of Build-A-Bear Workshop, Inc. 

Long-Term Performance-Based Cash Incentive Program for Chiefs

 

The purpose of the Build-A-Bear Workshop, Inc. (the “Company”) Long-Term Performance-Based Cash Incentive Program for Chiefs (the “Program”) is to attract and retain highly qualified executive officers, motivate these executive officers to materially contribute to the Company’s business success, and align the interests of the Company’s executive officers and stockholders by rewarding the executive officers for performance based on achievement of long-term targets established by the Compensation and Development of the Company’s Board of Directors (the “Committee”). The Program has been adopted under the Company’s 2017 Omnibus Incentive Plan (the “2017 Plan”).

 

The Committee in its discretion determines which Chiefs of the Company are eligible to participate in the Program. The cash award, if any, to be earned by each Chief will be calculated by multiplying the applicable Target Payout Amount for the respective Chief by the average of the applicable Percentage of Target Payout Amount Earned for each of the three consecutive fiscal years beginning with the fiscal year in which applicable award is made. 

 

The Percentage of Target Payout Amount Earned is set based on the achievement of one or more performance objectives as follows: (i) a threshold achievement of 25% of the performance objective; (ii) a target achievement of 100% of the performance objective; and (iii) a maximum achievement of 200% of the performance objective (the “Achievement Levels”). The applicable performance objectives will be established by the Committee within the first ninety (90) days of the fiscal year in which the applicable award is made and will be based on one or more categories of performance measures set forth in Section 9 of the 2017 Plan. The applicable performance objectives for years following the year in which the award is made will be based on growth rates over actual results for the prior year with such growth rates established within the first ninety (90) days of the fiscal year in which the applicable award is made. The calculation of awards earned will be interpolated to reflect performance results which fall within any of the Achievement Levels, in the sole discretion of the Committee. 

 

In the event of a financial restatement impacting the applicable performance objective after an earned award has been paid, the Company shall recover from the recipient of such earned award the applicable amount of the earned award which should not have been paid, based on the restatement of the performance objective, plus interest at the rate determined by the Committee, from the time Company made such earned award payment to the recipient until its recovery thereof. The recovery of any earned award paid pursuant to the Program shall be made in accordance with the terms of any incentive compensation recoupment or recovery policy adopted in the future by the Company pursuant to Rule 10D-1 of the Securities Exchange Act of 1934, as amended, and applicable rules and regulations of the New York Stock Exchange, or any national securities exchange on which the Company’s common stock is then-listed, to the extent that such policy would apply to such cash payments.March 20, 2018

 ARTICLE I 

DEFINITIONS 
 All
capitalized terms used herein shall have the meanings assigned to such terms in the Series 2018-1 Supplemental Definitions List attached hereto as Annex A (the

With respect to the Series 2018-1 Class A Notes only, the following shall apply:

 Section 3.1 Allocations with Respect to the Series 2018-1

be deposited into the Class A Notes Interest Reserve Account, $3,306,330 of the net proceeds from the initial sale of the Series 2018-1 Class A Notes will be deposited to the Required Expense
Reserve Account and the remainder of the net proceeds will be distributed or otherwise transferred to, or at the direction of, the Issuers. 

Section 3.2 Quarterly Allocation Date Applications; Quarterly Payment Date Applications. On each Quarterly
Allocation Date, the Issuers (or the Manager on their behalf) shall instruct the Trustee in writing to allocate from the Collection Account all amounts relating to the Series 2018-1 Class A Notes pursuant
to, and to the extent that funds are available therefor in accordance with the provisions of, the Priority of Payments. On each Quarterly Payment Date, the Trustee shall, based solely on the information contained in the most recent Quarterly
Manager’s Certificate received by the Trustee on the Quarterly Allocation Date relating to such Quarterly Payment Date, withdraw the amounts on deposit in the Collection Account on such Quarterly Payment Date allocable to the Series 2018-1 Class A Noteholders in accordance with the Priority of Payments and remit such amounts to the Series 2018-1 Class A Noteholders pursuant to
Section 5.9 of the Base Indenture for the payment of interest and, to the extent applicable, principal and Class A Make-Whole Prepayment Premium on such Quarterly Payment Date. 

Section 3.3 Allocations Among Class A Notes. 

Notwithstanding anything to the contrary herein or in the Base Indenture, if an additional Tranche of Class A Notes is
issued and Outstanding pursuant to the Base Indenture, except as provided under Section 3.6(f), each payment in respect of the Class A Notes shall be distributed between the Tranches in accordance with (A) such amounts due with
respect to interest on, principal of, Class A Make-Whole Prepayment Premium or otherwise with respect to such Tranches as provided hereunder or (B) if not otherwise provided hereunder, the Tranche Percentage of such payment amount
applicable to each such Tranche; provided that, in each case, any shortfall in such payment amount shall be allocated based on the Tranche Percentage applicable to each such Tranche; provided, further, that all distributions to
Noteholders of a Tranche shall be ratably allocated among the Noteholders within each applicable Tranche based on their respective portion of the Outstanding Principal Amount of such Tranche. 

Section 3.4 [Intentionally Omitted] 

Section 3.5 Series 2018-1 Class A
Interest. 
 (a) Series 2018-1 Class A
Note Rate. From the Series 2018-1 Closing Date until the Series 2018-1 Class A Outstanding Principal Amount with respect to a Tranche has been reduced
to zero, each Tranche of Series 2018-1 Class A Notes (after giving effect to all payments of principal made to Noteholders as of the first day of each Interest Accrual Period or, if such day is not a
Quarterly Payment Date, as of the following Quarterly Payment Date, and also giving effect to repurchases and cancellations 

  
 2 

 
of Series 2018-1 Class A Notes during such Interest Accrual Period) will accrue interest at the applicable
Series 2018-1 Class A Note Rate. Such accrued interest will be due and payable in arrears on each Quarterly Payment Date, from amounts that are made available for payment thereof (i) on any
related Quarterly Allocation Date in accordance with the Priority of Payments, amounts on deposit in the Collection Account and, if necessary, amounts on deposit in the Class A Notes Interest Reserve Account and amounts available under the
Interest Reserve Letters of Credit to fund the Class A Notes Accrued Quarterly Interest Shortfall and (ii) on such Quarterly Payment Date in accordance with Section 5.9 of the Base Indenture, commencing on June 20, 2018;
provided that in any event all accrued but unpaid interest on a Tranche of Series 2018-1 Class A Notes shall be due and payable in full on the
Series 2018-1 Legal Final Maturity Date, on any Series 2018-1 Prepayment Date with respect to a prepayment in full of such Tranche of Series 2018-1 Class A Notes or on any other day on which the Series 2018-1 Class A Outstanding Principal Amount of such Tranche of Series 2018-1 Class A Notes is required to be paid in full. Failure to pay the full Class A Notes Accrued Quarterly Interest Amount that is due and payable on any Quarterly Payment Date, which failure continues
for five (5) Business Days after an Authorized Officer of the Manager has Actual Knowledge thereof, will be an Event of Default, and to the extent any interest accruing at the Series 2018-1
Class A Note Rate is not paid when due, such unpaid interest with respect to each Tranche of Series 2018-1 Class A Notes will accrue interest to the extent legally permissible at the Series 2018-1 Class A Note Rate applicable to the Tranche of Series 2018-1 Class A Notes with respect to which such amount was not paid plus 2.0% per annum (the
“Default Rate”). All computations of interest at the Series 2018-1 Class A Note Rate shall be made on the basis of a year of 360 days and
twelve 30-day months. 
 (b) Series 2018-1 Class A Initial Interest Accrual Period. The initial Interest Accrual Period for the Series 2018-1 Class A Notes shall commence
on (and include) the Series 2018-1 Closing Date and end on (and exclude) the Quarterly Payment Date in June 2018. 

Section 3.6 Payment of Series 2018-1 Note Principal.

 (a) Series 2018-1 Class A Notes Principal Payment at Legal
Maturity. The Series 2018-1 Class A Outstanding Principal Amount shall be due and payable on the Series 2018-1 Legal Final Maturity Date. The Series 2018-1 Class A Outstanding Principal Amount is not prepayable, in whole or in part, except as set forth in this Section 3.6. 

(b) Series 2018-1 Anticipated Repayment. The
“Series 2018-1 Anticipated Repayment Date” means, (i) with respect to the Series 2018-1
Class A-1 Notes, the Quarterly Payment Date occurring in March 2025 (the “Series 2018-1
Class A-1 Anticipated Repayment Date”) and (ii) with respect to the Series 2018-1
Class A-2 Notes, the Quarterly Payment Date occurring in March 2028 (the “Series 2018-1
Class A-2 Anticipated Repayment Date”). The failure to pay or refinance the Series 2018-1
Class A-1 Outstanding Principal Amount or Series 2018-1 Class A-2 Outstanding Principal Amount in full by the relevant
Tranche’s Series 2018-1 Anticipated Repayment Date will not be an Event of Default but will be a Rapid Amortization Event. 

(c) Payment of Quarterly Scheduled Principal Amount and Quarterly Scheduled Principal Deficiency Amount. 

(i) The Quarterly Scheduled Principal Amount and any Quarterly Scheduled Principal Deficiency Amount will be allocated in
accordance with Section 5.8 of the Base Indenture on each Quarterly Allocation Date in accordance with the Priority of Payments. 

  
 3 

 (ii) The Quarterly Scheduled Principal Amount and any Quarterly Scheduled
Principal Deficiency Amount will be due and payable on each Quarterly Payment Date in accordance with Section 5.9 of the Base Indenture. 

(iii) If on any Quarterly Payment Date, the amount of funds on deposit in the Collection Account that is available to pay the
Quarterly Scheduled Principal Amount and any Quarterly Scheduled Principal Deficiency Amount with respect to the Series 2018-1 Class A Notes on such Quarterly Payment Date is less than the sum of
(a) the Quarterly Scheduled Principal Amount due and payable, if any, on the related Quarterly Payment Date and (b) the Quarterly Scheduled Principal Deficiency Amount, if any, then on each subsequent Quarterly Payment Date, 100% of funds
available pursuant to clause (ix) of the Priority of Payments will be paid to the applicable Series 2018-1 Class A Noteholders until the Quarterly Scheduled Principal Amount and the Quarterly
Scheduled Principal Deficiency Amount due and payable have been paid in full. Failure to pay any Quarterly Scheduled Principal Amount or any Quarterly Scheduled Principal Deficiency Amount shall not be an Event of Default provided all available
funds in the Collection Account have been paid to the Class A Noteholders in accordance with the Priority of Payments on the applicable Quarterly Payment Date. 

(d) Series 2018-1 Class A Notes Mandatory Payments of
Principal. 
 During any Rapid Amortization Period, principal payments shall be due and payable on each Quarterly
Payment Date on the applicable Tranche of Series 2018-1 Class A Notes as and when amounts are made available for payment thereof (i) on any related Quarterly Allocation Date in accordance with the
Priority of Payments and (ii) on such Quarterly Payment Date in accordance with Section 5.9 of the Base Indenture, in the amount so available, together with any Class A Make-Whole Prepayment Premium required to be paid in connection
therewith pursuant to Section 3.6(e) of this Series Supplement; provided, for the avoidance of doubt, that it shall not constitute an Event of Default if any such Class A Make-Whole Prepayment Premium is not paid because
insufficient funds are available to pay such Class A Make-Whole Prepayment Premium in accordance with the Priority of Payments. Such payments shall be ratably allocated among the Series 2018-1
Class A Noteholders within each Tranche, as applicable, based on their respective portion of the Series 2018-1 Class A Outstanding Principal Amount of such Tranche. 

(e) Class A Make-Whole Prepayment Premium. 

In connection with any mandatory prepayment of any Series 2018-1 Class A
Notes made during a Rapid Amortization Period pursuant to Section 3.6(d), or in connection with any optional prepayment of any Tranche of Series 2018-1 Class A Notes made pursuant to
Section 3.6(f), or any other payment or prepayment of principal whatsoever on each Tranche of Series 2018-1 Class A Notes (including pursuant to an Event of Default, mandatory or optional prepayment
or any Rapid Amortization Event) (each, a “Series 2018-1 Class A Prepayment”), in each case (x) with respect to the Series 2018-1 Class A-1 Notes, prepayments prior to the Quarterly Payment Date in March 2024 and (y) with respect to the Series
2018-1 Class A-2 Notes, prepayments prior to the Quarterly Payment Date in March 2027 (each such date, a “Class A Make-Whole End
Date”), the Issuers shall pay, in the manner described herein and in accordance with the Priority of Payments, the Class A Make-Whole Prepayment Premium to the applicable Series 2018-1
Class A Noteholders; provided that no such Class A Make-Whole Prepayment Premium shall be payable, in connection with (i) a Quarterly Scheduled Principal Amount on the date originally scheduled therefor on the Closing Date
(regardless of whether the Class A Notes are otherwise subject to a mandatory prepayment on such date, but only in respect of the amount of such payment that is equal to the Quarterly Scheduled Principal Amount due on such date) and
(ii) payments in connection with a Change of Control Offer. For the avoidance of doubt, no Class A Make-Whole 

  
 4 

 
Prepayment Premium will be payable with respect to any Tranche of Series 2018-1 Class A Notes after such Tranche’s Class A Make-Whole End
Date. 
 The “Class A Make-Whole Prepayment Premium” means, with respect to each Tranche
of Series 2018-1 Class A Notes, the amount calculated by the Manager on behalf of the Issuers equal to the sum of the present value of the Remaining Scheduled Interest Payments discounted to the date of
the relevant payment or prepayment of the Tranche of Series 2018-1 Class A Notes being prepaid (the principal amount of the Tranche of Series 2018-1 Class A
Notes subject to such payment or prepayment, the “Subject Principal Amount”), on a quarterly basis, assuming a 360-day year consisting of twelve 30-day
months, at the rate equal to the sum of (x) with respect to the Tranche of Series 2018-1 Class A Notes being prepaid, the yield to maturity (adjusted to a quarterly bond-equivalent basis) of the
United States Treasury Security having a maturity closest to the period equal to the remaining Weighted Average Life of such Tranche of Series 2018-1 Class A Notes as of the relevant date of prepayment
(the “Treasury Rate”) plus (y) 50 basis points (determined as of the relevant Series 2018-1 Class A Make-Whole Premium Calculation Date). For the avoidance of doubt, the
Class A Make-Whole Prepayment Premium shall include amounts due in accordance with the first paragraph of this clause (e). 

“Remaining Scheduled Interest Payments” means, with respect to the Subject Principal Amount of the Tranche of
Series 2018-1 Class A Notes being prepaid, the remaining payments of the interest thereon that would be due but for the prepayment of such Subject Principal Amount from (and including) the date of such
prepayment to (and excluding) the relevant Tranche’s Series 2018-1 Anticipated Repayment Date, assuming that the Subject Principal Amount of the Tranche of Series
2018-1 Class A Notes being prepaid is applied to reduce the Quarterly Scheduled Principal Amount ratably for each remaining Quarterly Payment Date and accordingly, in determining the Remaining Scheduled
Interest Payments (and resulting period over which interest payments are foregone) in respect of such Subject Principal Amount, such calculation will take into account the prepayment of the Subject Principal Amount as allocated in this manner. 

Failure to pay any Class A Make-Whole Prepayment Premium on any Quarterly Payment Date (other than the Series 2018-1 Legal Final Maturity Date and any other date on which the Series 2018-1 Class A Notes must be paid in full) is not an Event of Default under the Indenture. 

If any Tranche of Series 2018-1 Class A Notes are accelerated or otherwise become
due prior to the Series 2018-1 Legal Final Maturity Date, in each case, as a result of an Event of Default (including upon the occurrence of a bankruptcy or insolvency event (including the acceleration of
claims by operation of law)), the amount of principal of, and premium on, the Tranche of Series 2018-1 Class A Notes that becomes due and payable shall equal 100% of the applicable Series 2018-1 Class A Outstanding Principal Amount on such date plus the applicable Class A Make-Whole Prepayment Premium, determined on such date as if such Tranche of Series
2018-1 Class A Outstanding Principal Amount were voluntarily prepaid as of such date, and shall constitute part of the Issuers’ Obligations under the Indenture and Obligations of the Guarantors under
the Guarantee and Collateral Agreement. Any Class A Make-Whole Prepayment Premium payable above shall be presumed to be the liquidated damages sustained by each Noteholder as the result of the early prepayment and the Issuers agree that it is
reasonable under the circumstances currently existing. The applicable Class A Make-Whole Prepayment Premium shall also be payable in the event any Tranche of Series 2018-1 Class A Notes (and/or the
Indenture) are satisfied or released by foreclosure (whether by power of judicial proceeding), deed in lieu of foreclosure or by any other means, as if such satisfaction or release were an optional prepayment of the Tranche of Series 2018-1 Class A Notes so satisfied or released. THE ISSUERS EXPRESSLY WAIVE (TO THE FULLEST EXTENT THEY MAY LAWFULLY DO SO) THE PROVISIONS OF ANY PRESENT OR FUTURE STATUTE OR LAW THAT PROHIBITS OR MAY PROHIBIT
THE COLLECTION OF THE FOREGOING PREMIUMS IN CONNECTION WITH ANY SUCH 

  
 5 

 
ACCELERATION. The Issuers expressly agree (to the fullest extent they may lawfully do so) that: (A) the Class A Make-Whole Prepayment Premium is reasonable and is the product of an
arm’s length transaction between sophisticated business people, ably represented by counsel; (B) the Class A Make-Whole Prepayment Premium shall be payable notwithstanding the then prevailing market rates at the time payment is made;
(C) there has been a course of conduct between Noteholders and the Issuers giving specific consideration in this transaction for such agreement to pay the prepayment premiums; and (D) the Issuers shall be estopped hereafter from claiming
differently than as agreed to in this paragraph. The Issuers expressly acknowledge that their agreement to pay the Class A Make-Whole Prepayment Premium to Noteholders as herein described is a material inducement to Noteholders to purchase the
Series 2018-1 Class A Notes. 
 (f) Optional Prepayment of
Series 2018-1 Class A Notes. 
 Subject to
Section 3.6(e) and (g) of this Series Supplement, the Issuers may optionally prepay the Series 2018-1 Class A Outstanding Principal Amount of all or any Tranche of the Series 2018-1 Class A Notes (an “Optional Prepayment”) in whole on any Business Day or in part on any Quarterly Payment Date (each, an “Optional Prepayment Date”), without any
obligation to prepay the Notes of another Series or Tranche proportionately or otherwise, at a price equal to 100% of the aggregate principal amount of the Series 2018-1 Class A Notes prepaid plus accrued
and unpaid interest, if any, to but excluding the applicable Optional Prepayment Date; provided that any such Optional Prepayment at any time before the applicable Class A Make-Whole End Date will also include the Class A Make-Whole

Prepayment is made (if such Change of Control Prepayment is made on a Quarterly Prepayment Date) or on the Quarterly Payment Date immediately following the date on which such Change of Control Prepayment is made (if such Change of Control Prepayment
is not made on a Quarterly Prepayment Date). 
 (d) The Issuers shall comply with the requirements of Rule 14e-1 under the 1934 Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with any Change of Control Prepayment. To the extent that the
provisions of any securities laws or regulations conflict with the provisions of the Indenture relating to a Change of Control Prepayment, the Issuers shall comply with the applicable securities laws and regulations and shall not be deemed to have
breached their obligations under such provisions of the Indenture by virtue of such conflicts. 
 (e) The Issuers shall not
be required to effect a Change of Control Prepayment upon the occurrence of a Change of Control Triggering Event if and to the extent that a third party consummates such Change of Control Prepayment in the manner, at the times and otherwise in
compliance with the requirements for a Change of Control Prepayment applicable to the making of a Change of Control Prepayment by the Issuers and such third party purchases all or the part of the Prepayment Notes properly tendered and not withdrawn,
in accordance with the requirements set forth in the Indenture (and any such prepayment shall constitute a “Change of Control Prepayment” for purposes of the Indenture). 

(f) If Class A Noteholders of at least 90% in Outstanding Principal Amount of the Class A Notes are Accepting
Noteholders and the Issuers (or any third-party making an offer in lieu of the Issuers, as described above) have effected a Change of Control Prepayment in respect of such Prepayment Notes, the Issuers (or such third party) shall have the right,
upon not less than thirty (30) nor more than sixty (60) days’ prior notice, given not more than thirty (30) days following such Change of

Control Prepayment, to prepay all Class A Notes that remain Outstanding at the Change of Control Prepayment Price for such Class A Notes. 

(g) In respect of a Change of Control Prepayment: 

A “Rating Event” means any Outstanding Tranche of Class A Notes either (i) has its rating withdrawn
by either Rating Agency or (ii) is rated below the lower of (A) the then-current credit ratings on such Outstanding Tranche of Class A Notes by either Rating Agency or (B) the initial credit ratings assigned to such Outstanding
Tranche of Class A Notes by either Rating Agency (in each case, without negative implications) in each case from the date of the public notice of an arrangement that could result in a Change of Control until the end of the 60-day period following public notice of the occurrence of the Change of Control (which 60-day period shall be extended so long as the rating of the Class A Notes is
under publicly announced consideration for possible downgrade by either of the Rating Agencies as a result of, or in respect of, the applicable Change of Control); provided that (i) a Rating Event arising by virtue of a particular
reduction in rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Rating Event for purposes of the definition of Change of Control Triggering Event) if any of the Rating Agencies
does not announce or publicly confirm or inform the Trustee in writing at the Issuers’ or its request that the reduction in ratings was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in
respect of, the applicable Change of Control (whether or not the applicable Change of Control has been consummated at the time of such Rating Event); and (ii) no Rating Event shall be deemed to have occurred if the Issuers obtain within the
time periods set forth in this definition of “Rating Event” a Rating Agency Confirmation in respect of such Change of Control where, solely for purposes of determining whether a Rating Event has occurred, “Rating Agency
Confirmation” means, with respect to any Outstanding Tranche of Class A Notes, a written confirmation from the Rating Agencies that such Change of Control shall not result in either (i) a withdrawal of its credit ratings on such
Outstanding Tranche of Class A Notes or (ii) the assignment of credit ratings on such Outstanding Tranche of Class A Notes below the lower of (A) the then-current credit ratings on such Outstanding Tranche of Class A Notes
or (B) the initial credit ratings assigned to such Outstanding Tranche of Class A Notes by such Rating Agency (in each case, without negative implications). 

“Change of Control” means a “change of control” as defined in the Sprint Credit Agreement as in
effect as of the 2016 Closing Date (regardless of any references in the Sprint Credit Agreement to future amendments or modifications thereto). 

“Change of Control Triggering Event” means the occurrence of both a Change of Control and a Rating Event.

 (k) The required legends set forth above shall
not be removed from the applicable Series 2018-1 Class A Notes except as provided herein. The legend required for a Rule 144A Global Note may be removed from such Rule 144A Global Note if
there is delivered to the Issuers and the Registrar such satisfactory evidence, which may include an Opinion of Counsel, as may be reasonably required by the Issuers that neither such legend nor the restrictions on transfer set forth therein are
required to ensure that transfers of such Rule 144A Global Note will not violate the registration requirements of the Securities Act. Upon provision of such satisfactory evidence, the Trustee at the direction of the Issuers (or the Manager on
their behalf), shall authenticate and deliver in exchange for such Rule 144A Global Note a Series 2018-1 Class A Note or Series 2018-1 Class A
Notes having an equal aggregate principal amount that does not bear such legend. If such a legend required for a Rule 144A Global Note has been removed from a Series 2018-1 Class A Note as
provided above, no other Series 2018-1 Class A Note issued in exchange for all or any part of such Series 2018-1 Class A Note shall bear such legend,

 If the Trustee is notified by the Issuers that (i) a
transfer or attempted or purported transfer of any interest in a Series 2018-1 Class A Note was not consummated in compliance with the applicable transfer provisions on the basis of an incorrect form or
certification from the transferee or purported transferee, (ii) a transferee failed to deliver to the Trustee any form or certificate required to be delivered under the Indenture or (iii) the holder of any interest in a Note is in breach
of any representation or agreement set forth in any certificate or any deemed representation or agreement of such holder, the Trustee will not register such attempted or purported transfer and if a transfer has been registered, such transfer will be
absolutely null and void ab initio and will vest no rights in the purported transferee (such purported transferee, a “Disqualified Transferee”) and the last preceding holder of such interest in such Series 2018-1 Class A Note that was not a Disqualified Transferee will be restored to all rights as a Noteholder thereof retroactively to the date of transfer of such Series
2018-1 Class A Note by such Noteholder. Without limitation, Persons who are not Qualified Purchasers or are (other than following any Rapid Payment Event) Competitors will be Disqualified Transferees.

Section 4975 of the Code or (ii) the holder’s acquisition, holding and disposition of this Note (or any interest herein) will not constitute or result in a non-exempt prohibited transaction

any similar law). In addition, each holder that is a Plan, by acceptance of this Note, will be deemed to have represented and warranted that a fiduciary acting on its behalf is causing it to purchase this Note and that such fiduciary: (A) is a
bank, an insurance carrier, a registered investment adviser, a registered broker-dealer or an independent fiduciary with at least $50 million of assets under management or control as specified in 29 CFR

give advice in a fiduciary capacity, in connection with the holder’s transactions with the Transaction Parties contemplated hereby; (E) is a “fiduciary” under Section 3(21)(A) of ERISA or Section 4975(e)(3) of the Code,
or both, as applicable, with respect to, and is responsible for exercising independent judgment in evaluating, the holder’s transactions with the Transaction Parties contemplated hereby; and (F) understands and acknowledges the existence
and nature of the underwriting discounts, commissions and fees, and any other related fees, compensation arrangements or financial interests, described in this offering memorandum; and understands, acknowledges and agrees that no such fee or other
compensation is a fee or other compensation for the provision of investment advice, and that none of the Transaction Parties, nor any of their respective directors, officers, members, partners, employees, principals or agents has received or will
receive a fee or other compensation from the holder or such fiduciary for the provision of investment advice (rather than other services) in connection with the holder’s transactions with the Transaction Parties contemplated hereby. 

The term “Issuers” as used in this Note includes any successor to any Issuer under the Indenture. 

The Series 2018-1 Class A-1 Notes
are issuable only in registered form in denominations as provided in the Indenture, subject to certain limitations set forth therein. 

This Note and the Indenture shall be governed by, and construed and interpreted in accordance with, the laws of the State of

and nature of the underwriting discounts, commissions and fees, and any other related fees, compensation arrangements or financial interests, described in this offering memorandum; and understands, acknowledges and agrees that no such fee or other
compensation is a fee or other compensation for the provision of investment advice, and that none of the Transaction Parties, nor any of their respective directors, officers, members, partners, employees, principals or agents has received or will
receive a fee or other compensation from the holder or such fiduciary for the provision of investment advice (rather than other services) in connection with the holder’s transactions with the Transaction Parties contemplated hereby.

upon such holders of Series 2018-1 Class A-1 Notes and upon all future holders of Series 2018-1 Class A-1 Notes of this Note and of any Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such consent or waiver is made upon this Note.

Section 4975 of the Code or (ii) the holder’s acquisition, holding and disposition of this Note (or any interest herein) will not constitute or result in a non-exempt prohibited transaction

any similar law). In addition, each holder that is a Plan, by acceptance of this Note, will be deemed to have represented and warranted that a fiduciary acting on its behalf is causing it to purchase this Note and that such fiduciary: (A) is a

and nature of the underwriting discounts, commissions and fees, and any other related fees, compensation arrangements or financial interests, described in this offering memorandum; and understands, acknowledges and agrees that no such fee or other
compensation is a fee or other compensation for the provision of investment advice, and that none of the Transaction Parties, nor any of their respective directors, officers, members, partners, employees, principals or agents has received or will
receive a fee or other compensation from the holder or such fiduciary for the provision of investment advice (rather than other services) in connection with the holder’s transactions with the Transaction Parties contemplated hereby. 

The term “Issuers” as used in this Note includes any successor to any Issuer under the Indenture. 

The Series 2018-1 Class A-1 Notes
are issuable only in registered form in denominations as provided in the Indenture, subject to certain limitations set forth therein.

receive a fee or other compensation from the holder or such fiduciary for the provision of investment advice (rather than other services) in connection with the holder’s transactions with the Transaction Parties contemplated hereby.

Section 4975 of the Code or (ii) the holder’s acquisition, holding and disposition of this Note (or any interest herein) will not constitute or result in a non-exempt prohibited transaction

any similar law). In addition, each holder that is a Plan, by acceptance of this Note, will be deemed to have represented and warranted that a fiduciary acting on its behalf is causing it to purchase this Note and that such fiduciary: (A) is a

and nature of the underwriting discounts, commissions and fees, and any other related fees, compensation arrangements or financial interests, described in this offering memorandum; and understands, acknowledges and agrees that no such fee or other
compensation is a fee or other compensation for the provision of investment advice, and that none of the Transaction Parties, nor any of their respective directors, officers, members, partners, employees, principals or agents has received or will
receive a fee or other compensation from the holder or such fiduciary for the provision of investment advice (rather than other services) in connection with the holder’s transactions with the Transaction Parties contemplated hereby. 

The term “Issuers” as used in this Note includes any successor to any Issuer under the Indenture. 

The Series 2018-1 Class A-2 Notes

null and void ab initio. 
 The Transferee understands that the Issuers, the Trustee, the Registrar and their
respective counsel will rely upon the accuracy and truth of the foregoing representations, and are irrevocably authorized to produce this certificate or a copy thereof to any interested party in any administrative or legal proceeding or official

The Transferee understands that the Issuers, the Trustee, the Registrar and their respective counsel will rely upon the
accuracy and truth of the foregoing representations, and are irrevocably authorized to produce this certificate or a copy hereof to any interested party in any administrative or legal proceedings or official inquiry with respect to any matter

 The Issuers and initial purchasers are putting participants on notice that they
are required to follow these purchase and transfer restrictions with regard to the above-referenced security. 
 In order to
qualify for the exemption provided by Section 3(c)(7) under the Investment Company Act of 1940, as amended (the “1940 Act”), and the exemption provided by Rule 144A under the Securities Act of 1933, as amended
(the “1933 Act”), or Regulation S of the 1933 Act, as applicable, offers, sales and resales of the [Series 2018-1 4.738% Senior Secured Notes, Class A-1]/[Series 2018-1 5.152% Senior Secured Notes, Class A-2] (the “Securities”) may only be made in minimum denominations of
$200,000 and integral multiples of $1,000 in excess thereof (the “Authorized Minimum Denomination”) (x) within the United States to “qualified institutional buyers” (“QIBs”) within the meaning of
Rule 144A that are also “qualified purchasers” (“QPs”) within the meaning of Section 2(a)(51)(A) of the 1940 Act and Rule 2a51-1 promulgated thereunder and
(y) outside of the United States to QPs that are not U.S. persons (as defined in Regulation S). Each purchaser of Securities (1) represents to and agrees with the Issuers and the initial purchasers that (i)(a) with respect
to Notes that were purchased in the United States, the purchaser is not (other than following any Rapid Payment Event) a Competitor and is a QIB who is a QP (a “QIB/QP”) and (b) with respect to Notes that were purchased outside
the United States, the purchaser is not (other than following any Rapid Payment Event) a Competitor and is a QP who is not a U.S. person (as defined in Regulation S); (ii) the purchaser is not a broker-dealer who owns and invests on a
discretionary basis less than $25,000,000 in securities of unaffiliated issuers; (iii) the purchaser is not a participant-directed employee plan, such as a 401(k) plan; (iv) the QIB/QP is acting for its own account, or the account of
another QIB/QP; (v) the purchaser is not formed for the purpose of investing in the Issuers; (vi) the purchaser, and each account for which it is purchasing, will hold and transfer at least the minimum denomination of Securities;
(vii) the purchaser understands that the Issuers may receive a list of participants holding positions in its securities from one or more book-entry depositaries; (viii) the purchaser will provide notice of the transfer restrictions to any
subsequent transferees; and (ix) is not (other than following any Rapid Payment Event) a Competitor and (2) acknowledges that the Issuers have not been registered under the 1940 Act and the Securities have not been registered under
the 1933 Act and represents to and agrees with the Issuers and the initial purchasers that, for so long as securities are outstanding, it will not offer, resell, pledge or otherwise transfer the Securities except to a QIB that is also a QP in a
transaction meeting the requirements of Rule 144A or to a Qualified Purchaser that is not a U.S. Person in a transaction meeting the requirements of Regulation S. Each purchaser further understands that the Securities will bear a legend with
respect to such transfer restrictions. See “Transfer Restrictions” in the Offering Memorandum. 

The charter, bylaws, organizational documents or securities issuance documents of the Issuers provide that the Issuers will
have the right to (i) require any holder of Securities who is determined to be (other than following any Rapid Payment Event) a Competitor or not to be both a QIB and a QP not a U.S. Person in a transaction meeting the requirements of
Regulation S to sell the Securities to a Person who is not (other than following any Rapid Payment Event) a Competitor who is a QIB that is also a QP or not a U.S. Person in a transaction meeting the requirements of Regulation S or (ii) redeem
any Securities held by such a holder on specified terms. In addition, the Issuers have the right to refuse to register or otherwise honor a transfer of Securities to a proposed transferee that is (other than following any Rapid Payment Event) a
Competitor or not both a QIB and a QP. 
 The restrictions on transfer required by the Issuers (outlined above) will be
reflected [under the notation “3c7” in DTC’s User Manuals and DTC’s Reference Directory] [Annex 3(c)(7) of Euroclear’s New Issues Acceptance Guide] [Chapter 7 (“Custody Business Operations — New
Issues”), Section 7.3 (“General Procedure for the admission and distribution of new issues of syndicated international instruments”) in Clearstream Banking’s Directory].
