 For and in consideration of the premises and the other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, the Company, the Guarantors and the Trustee mutually agree as follows: 
 ARTICLE I 
 Definitions and Other Provisions of General Application

 SECTION 1.01 Definitions. 
 Except as otherwise expressly provided or unless the context otherwise requires, all terms used in this Eleventh Supplemental Indenture which are defined in the Indenture shall have the meanings ascribed
to them by the Indenture. The following terms used in this Eleventh Supplemental Indenture have the following respective meanings:

 “Applicable Exchange Rate”
means, for any Exchange Rate Determination Date, the rate determined by the Calculation Agent that is equal to the Brazilian real/U.S. dollar commercial rate, expressed as the amount of Brazilian reais per one U.S. dollar as reported
by Banco Central Do Brasil (the “Central Bank”) on the SISBACEN Data System under transaction code PTAX800 (“Consultas de Câmbio” or Exchange Rate Enquiry), Option 5, “Venda” (“Cotações para
Contabilidade” or Rates for Accounting Purposes) (or any successor screen established by the Central Bank), for such Exchange Rate Determination Date (the “PTAX Rate”); provided, however, that if the PTAX Rate scheduled
to be reported on any Exchange Rate Determination Date is not reported by the Central Bank on such Exchange Rate Determination Date, then the Applicable Exchange Rate will be BRL12; in the event BRL12 is unavailable, then the Applicable Exchange
Rate will be BRL13. If the Applicable Exchange Rate cannot be calculated as described above, the Calculation Agent will determine the Applicable Exchange Rate by reference to the quotations received from three

leading Brazilian banks as shall be selected by the Company in its sole discretion (collectively, the “Reference Banks”). The quotations will be determined in each case for such
Exchange Rate Determination Date as soon as practicable after (i) it is determined that the Applicable Exchange Rate cannot be calculated as described above for such Exchange Rate Determination Date and (ii) the identities of the Reference
Banks are provided by the Company to the Calculation Agent by written notice. The Calculation Agent will ask each of the Reference Banks for quotations for the offered Brazilian real/U.S. dollar exchange rate for the sale of U.S. dollars. The
Applicable Exchange Rate will be the average of the Brazilian real/U.S. dollar exchange rates obtained from the Reference Banks. If only two quotations are obtained, the Applicable Exchange Rate will then be the average of the Brazilian
real/U.S. dollar exchange rates obtained from the Reference Banks. If only one quotation is obtained, the Applicable Exchange Rate will be that quotation. Where no such quotations are obtained from the Reference Banks, if the Company
determines in its sole discretion that there are one or two other suitable replacement banks active in the Brazilian real/U.S. dollar market, the Calculation Agent shall ask such banks to provide such quotations as soon as practicable after
the identity of such replacement bank is provided by the Company to the Calculation Agent by written notice and shall use such quotations as it receives to determine the Applicable Exchange Rate (taking an average rate, as set forth above, if
applicable); provided, however, that if the Reference Banks and any such replacement banks are not providing quotations in the manner described above, the Applicable Exchange Rate will be the Applicable Exchange Rate determined as of
the preceding Exchange Rate Determination Date.

November 9, 2010) EMTA conducts a twice-daily survey of up to 15 Brazilian financial institutions that are active participants in the Brazilian real/U.S. dollar spot market, with a required minimum participation of at least 5 financial
institutions. 
 “BRL13” means the EMTA BRL Indicative Survey Rate (BRL13), which is the final

EMTA (or a service provider EMTA may select in its sole discretion) using the EMTA BRL Industry Survey Methodology dated as of March 1, 2004, as amended from time to time, pursuant to which (as of November 9, 2010) EMTA conducts a survey
of up to 30 Brazilian and non-Brazilian financial institutions that are active participants in the Brazilian real/U.S. dollar spot market, with a required minimum participation of at least 8 financial institutions.

Applicable Exchange Rate for the applicable Exchange Rate Determination Date provided to it by the Calculation Agent. Interest will accrue from November 17, 2010 or 

  
 - 8 -

 
from the most recent Interest Payment Date to which interest has been paid or duly provided for, as the case may be. Interest is payable semi-annually on May 17 and November 17 of each
year (each, an “Interest Payment Date”), commencing May 17, 2011, and until full repayment of the outstanding principal of the Notes, to the Person in whose name the Notes were registered at the close of business on the
applicable Regular Record Date until the principal thereof is paid or made available for payment. 
 SECTION 2.04 Payment of
Principal, Interest and Other Amounts. Payments of principal of, premium, if any, and interest on the Notes shall be made, in U.S. dollars, as calculated by the Paying Agent, by translating the Brazilian real amount into U.S. dollars at
the Applicable Exchange Rate for the applicable Exchange Rate Determination Date provided to it by the Calculation Agent, through one or more Paying Agents appointed under the Indenture. Such payments of principal of, premium, if any, and interest
on the Notes represented by a Global Security shall be made through such Paying Agents to the Depositary or its nominee, as the Holder of the Global Security. Initially, the Paying Agent and Registrar for the Notes will be The Bank of New York
Mellon Trust Company, N.A., in St. Louis, Missouri. The Company may change the Paying Agent or Registrar without prior notice to the Holders of the Notes, and in such an event the Company may act as Paying Agent or Registrar. Payments of principal
of, premium, if any, and interest on the Notes represented by a Global Security shall be made by wire transfer of immediately available funds; provided, however, that in the case of payments of principal and premium, if any, such
Global Security is first surrendered to the Paying Agent. 
 SECTION 2.05 Calculation Agent. The Company will maintain a
calculation agent until all interest and principal payable on the Notes has been paid. The Calculation Agent will determine the Applicable Exchange Rate for the relevant Interest Payment Date, Redemption Date, Effective Date, Stated Maturity, or
date on which any payment is made in respect of the Notes following an acceleration of the maturity of the Notes, as the case may be, and shall provide notice of such Applicable Exchange Rate to the Company, the Trustee and the Paying Agent in the
manner contemplated in the Calculation Agent Agreement. All calculations made by the Calculation Agent for purposes of calculating the Applicable Exchange Rate will be conclusive and binding absent manifest error. The Company shall give the
Calculation Agent written notice of (i) a Redemption Date for the Notes to be redeemed promptly after notice of the redemption is given under Section 1104 of the Indenture and (ii) an Effective Date promptly after notice of such
Effective Date is given under Section 2.06(a)(ii) of this Eleventh Supplemental Indenture, but in no case less than three Business Days prior to the Redemption Date or Effective Date, as the case may be. The Trustee shall give the Calculation
Agent at least three Business Day’s notice of a payment on the Notes following an acceleration thereof. For purposes of the preceding two sentences, “Business Day” shall have the meaning set forth in the proviso to the definition of
that term contained in Section 1.01. Upon receipt of the Applicable Exchange Rate from the Calculation Agent, the Paying Agent will determine the amounts of principal and interest to be paid on the Notes on the basis of the Applicable Exchange
Rate in order to translate the amount of Brazilian reais to U.S. dollars.

 SECTION 2.06
Holders’ Option to Require Repayment upon a Change in Control. 
 (a) In the event that (a) a Change of Control
occurs, and (b) within the Change of Control Period, a Ratings Downgrade in respect of that Change of Control occurs (an “Early Redemption Event”): 
 (i) the Company will (A) within 30 days after becoming aware of the Early Redemption Event, provide written notice thereof to the Holders of the Notes, and (B) determine and provide written
notice of the effective date for the purposes of early repayment (the “Effective Date”). The Effective Date must be a Business Day not less than 60 and not more than 90 days after the giving of the notice regarding the Early
Redemption Event pursuant to subparagraph (i)(A); and 
 (ii) any Holder of Notes may, by submitting a redemption notice (the
“Early Redemption Notice”), demand from the Company repayment as of the Effective Date of any (in integral multiples of BRL 1,000 (provided that the unrepurchased portion must be in a principal amount of at least BRL
100,000)) or all of its Notes which have not otherwise been declared due for early redemption, at a repurchase price in cash of 101% of their principal amount plus interest accrued until (but excluding) the Effective Date (and all Additional
Amounts, if any). 
 (b) Any Early Redemption Notice shall be made in writing in English and shall be delivered by hand or by
registered mail to the Trustee not less than 30 days prior to the Effective Date at its specified office. The Early Redemption Notice must be accompanied by evidence showing that the relevant Holder is the Holder of the relevant Note(s) at the time
the Early Redemption Notice is delivered. Such evidence may be provided in the form of a certificate issued by any custodian or in any other suitable manner. Early Redemption Notices shall be irrevocable. 

(c) The Company shall not be required to redeem the Notes under this Section following an Early Redemption Event if a third party makes
an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all the Notes properly tendered and not withdrawn under its offer. The Company will also not be
required to redeem the Notes under this Section if it has otherwise exercised its rights to redeem the Notes in full pursuant to this Eleventh Supplemental Indenture or has defeased the Notes as described in the Indenture. 

(d) If, as a result of this Section 2.06, Holders of the Notes submit Early Redemption Notices in respect of at least 85% of the
aggregate principal amount of the Notes Outstanding, the Company shall have the ability by notice to the Trustee to 

  
 - 10 -

 
redeem the entire Outstanding principal amount of the Notes on the Effective Date at the same price as for the Notes being redeemed under this Section. Such notice shall be irrevocable and shall
be given to the Trustee no later than 15 days prior to the Effective Date. Irrevocable notice of such redemption shall be given to the Holders of the Notes in accordance with Section 1104 of the Indenture by the Company, or at the
Company’s request, by the Trustee, in the name and at the expense of the Company, in each case as soon as practicable after receipt by the Trustee of the foregoing notice from the Company. 

(e) The provisions set forth in this Section 2.06 will not be effective unless and until they are approved substantially in the form
provided herein by a resolution of the general meeting of shareholders of the Parent Guarantor. The Parent Guarantor will procure that a resolution to approve the terms of this Section 2.06 is presented to the shareholders of the Parent
Guarantor at the first annual general meeting after November 8, 2010 and at each successive annual general meeting of the Parent Guarantor thereafter until such resolution is approved and immediately following approval of such resolution the
Parent Guarantor will cause a copy thereof to be filed with the Clerk of the Commercial Court of Brussels (“greffe du tribunal de commerce/griffie van de rechtbank van koophandel”). The Parent Guarantor will notify the Trustee promptly
after each shareholder meeting of the results of the vote on the proposed resolution. If the general meeting of shareholders of the Parent Guarantor does not approve the provisions set forth in this Section 2.06 by the date that is eighteen
(18) months following the Original Issue Date, the interest rate applicable to the Notes will increase by 0.25% with effect from the next following day until the date that the Parent Guarantor notifies the Trustee that the provisions of this
Section 2.06 have been approved (or if such approval is no longer required in order for the Change in Control Clause to be effective), following which the interest rate applicable to the Notes will decrease by the same amount. 

SECTION 2.07 Optional Tax Redemption. 
 (a) The Company may, at the Company’s or the Parent Guarantor’s option, redeem the Notes in whole but not in part, upon not less than thirty (30) nor more than sixty (60) days’
prior notice, at a redemption price equal to 100% of the principal amount of the Notes then outstanding plus accrued and unpaid interest on the principal amount being redeemed (and all Additional Amounts, if any) to (but excluding) the Redemption
Date, if (i) as a result of any change in, or amendment to, the laws, treaties, regulations or rulings of a jurisdiction in which the Company or any Guarantor is incorporated, organized, or otherwise tax resident or any political subdivision or
any authority thereof or therein having power to tax, or in the interpretation, application or administration or any such laws, treaties, regulations or rulings (including a holding, judgment or order by a court of competent jurisdiction) which
becomes effective on or after the Original Issue Date (any such change or amendment, a “Change in Tax Law”), the Company or, if a payment were then due under a Guarantee, the relevant Guarantor,

  
 - 11 -

 
would be required to pay Additional Amounts and (ii) such obligation cannot be avoided by the Company or the relevant Guarantor taking reasonable measures available to it; provided, however,
that the Notes may not be redeemed to the extent such Additional Amounts arise solely as a result of the Company assigning its obligations under the Notes to a Substitute Company (as defined in Section 801 of the Indenture), unless such
assignment to a Substitute Company is undertaken as part of a plan of merger by the Parent Guarantor. 
 (b) Prior to the
mailing of any notice of redemption pursuant to this Section 2.07, the Company or the relevant Guarantor will deliver to the Trustee an opinion of independent tax counsel of recognized standing to the effect that the Company or the relevant

Anheuser-Busch InBev Worldwide Inc., a corporation duly organized and existing under the laws of the State of Delaware (herein called the
“Company”, which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., or its registered assigns, on November 17, 2015 (the
“Maturity Date”), the principal sum of BRL— translated into U.S. dollars at the Applicable Exchange Rate on the applicable Exchange Rate Determination Date relating to the Maturity
Date, and to pay interest thereon from November 17, 2010 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually on May 17 and November 17 in each year, commencing on
May 17, 2011, at the rate of 9.750% per annum (subject to increase as provided herein), translated into U.S. dollars at the Applicable Exchange Rate on the applicable Exchange Rate Determination Date until the principal hereof is paid or
made available for payment. 
 The interest so payable, and punctually paid or duly provided for on any Interest Payment Date
will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the May 2 or
November 2 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record
Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee,
notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on
which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. All payments of principal of and interest on this Security shall be made exclusively in such
coin or currency of the United States of America as at the time of payment and shall be legal tender for the payment of public and private debts. The Bank of New York Mellon, acting under the Calculation Agent Agreement (the “Calculation
Agent Agreement”) dated as of November 17, 2010, between the Company and The Bank of New York Mellon, as Calculation Agent (the “Calculation Agent”, which term includes

  
 A-2

  
 Exhibit A

  
 
any successor calculation agent under the Calculation Agent Agreement) will determine on the applicable Exchange Rate Determination Date (as defined herein) the Applicable Exchange Rate (as
defined herein) at which principal and interest will be translated from Brazilian reais into U.S. dollars. Thereafter the Paying Agent will determine the amount of principal and interest to be paid on the Securities based on the Applicable
Exchange Rate. 
 Subject to the terms of the Indenture, this Security is fully and unconditionally guaranteed as to all
payments due hereon whether at the Stated Maturity, by acceleration, redemption, repayment or otherwise in accordance with the terms of the Guarantees and the Indenture. 
 Payments of principal of (and premium, if any) and interest on the Securities represented by this Security shall be made in U.S. dollars through one or more Paying Agents appointed under the Indenture to
the Depositary or its nominee, as the Holder of this Security. Initially, the Paying Agent and Registrar for the Securities will be The Bank of New York Mellon Trust Company, N.A., St. Louis, Missouri. The Company may change the Paying Agent or
Registrar without prior notice to the Holders, and in such an event the Company may act as Paying Agent or Registrar. Payments of principal, premium, if any, and interest on the Securities represented by this Security shall be made by wire transfer
of immediately available funds; provided, however, that in the case of payments of principal and premium, if any, such Global Security is first surrendered to the Paying Agent.

 Exhibit A

  
 [REVERSE OF SECURITY] 

1. Securities and Indenture 
 This Security is one of a duly authorized issue of securities of the Company (payable in U.S. dollars) (herein called the “Securities”), issued and to be issued in one or more series
under an Indenture, dated as of October 16, 2009 (the “Base Indenture”), as supplemented by the Eleventh Supplemental Indenture, dated as of November 17, 2010 (the “Eleventh Supplemental Indenture” and
together with the Base Indenture, the “Indenture”), in each case among the Company, Anheuser-Busch InBev NV/SA, as Parent Guarantor, the Subsidiary Guarantors party thereto from time to time and The Bank of New York Mellon Trust
Company, N.A., as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Base Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of
rights, duties and immunities thereunder of the Company, the Guarantors, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. 

2. Series and Denomination 
 This Security is one of the series designated on the face hereof, initially limited to an aggregate principal amount of BRL 750,000,000, except as provided in the Indenture. References herein to
“this series” mean the series of securities designated on the face hereof. Except as provided in the preceding paragraph, references herein to the “Securities” mean (unless the context otherwise requires) the Securities of
this series and includes any other securities issued, as provided in the Indenture and forming a single series with the Securities of this series. 
 The Securities are issuable only in registered form without coupons in denominations of BRL 100,000 in principal amount and integral multiples of BRL 1,000 in excess thereof. 

3. Duties of the Calculation Agent and Paying Agent 
 The Company will maintain a calculation agent until all interest and principal payable on the Securities has been paid. The Calculation Agent shall calculate the Applicable Exchange Rate in order to
permit the Paying Agent to determine the amounts payable in U.S. dollars in respect of principal of and interest on the Securities for the relevant Interest Payment Date, Redemption Date, Effective Date, Stated Maturity or date on which any payment
is made in respect of the Securities following an acceleration of the maturity of the Securities, as the case may be. The Calculation Agent shall provide notice of such Applicable Exchange Rate to the Company, the Trustee and the Paying Agent in the
manner contemplated in the Calculation Agent Agreement. All calculations made by the Calculation Agent for purposes of calculating the Applicable Exchange Rate will be conclusive and binding absent manifest error. The Company shall give the
Calculation Agent written notice of (i) a Redemption Date for the Securities to be 

  
 A-5

  
 Exhibit A

  
 
redeemed promptly after notice of the redemption is given under Section 1104 of the Indenture and (ii) an Effective Date promptly after notice of such Effective Date is given under
Section 2.06(a)(i) of the Eleventh Supplemental Indenture, but in no case less than three Business Days prior to the Redemption Date or Effective Date, as the case may be. The Trustee shall give the Calculation Agent at least three Business
Day’s notice of a payment on the Securities following an acceleration thereof. For purposes of the preceding two sentences, “Business Day” shall have the meaning set forth in the proviso to the definition of that term contained in
Section 1.01 of the Eleventh Supplemental Indenture. Upon receipt of the Applicable Exchange Rate from the Calculation Agent, the Paying Agent will determine the amounts of principal and interest to be paid on the Securities on the basis of the
Applicable Exchange Rate in order to translate the amount of Brazilian reais to U.S. Dollars. 
 4. Repurchase at the
Option of Holder Upon a Change in Control 
 In the event that (a) a Change of Control occurs, and (b) within the
Change of Control Period, a Ratings Downgrade in respect of that Change of Control occurs (an “Early Redemption Event”): 
 (i) the Company will (A) within 30 days after becoming aware of the Early Redemption Event, provide written notice thereof to the Holders of the Securities, and (B) determine and provide written
notice of the effective date for the purposes of early repayment (the “Effective Date”). The Effective Date must be a Business Day not less than 60 and not more than 90 days after the giving of the notice regarding the Early
Redemption Event pursuant to subparagraph (i)(A); and 
 (ii) any Holder of Securities may, by submitting a redemption notice, in
the form attached as Annex A (the “Early Redemption Notice”), demand from the Company repayment as of the Effective Date of any (in integral multiples of BRL 1,000 (provided that the unrepurchased portion must be in a principal
amount of at least BRL 100,000)) or all of its Securities which have not otherwise been declared due for early redemption, at a repurchase price in cash of 101% of their principal amount plus interest accrued until (but excluding) the Effective Date
(and all Additional Amounts, if any). 
 Any Early Redemption Notice shall be made in writing in English and shall be delivered
by hand, by registered mail, or by facsimile transmission to the Trustee not less than 30 days prior to the Effective Date at its specified office. The Early Redemption Notice must be accompanied by evidence showing that the relevant Holder is the
Holder of the relevant Securities at the time the Early Redemption Notice is delivered. Such evidence may be provided in the form of a certificate issued by any custodian or in any other suitable manner. Early Redemption Notices shall be
irrevocable. 
 The Company shall not be required to redeem the Securities under this Section following an Early Redemption
Event if a third party makes an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the 

  
 A-6

  
 Exhibit A

  
 
Company and such third party purchases all the Securities properly tendered and not withdrawn under its offer. The Company will also not be required to redeem the Securities under this Section if
it has otherwise exercised it rights to redeem the Securities in full or has defeased the Securities as described in the Indenture. 
 If, as a result of this Section, Holders of the Securities submit Early Redemption Notices in respect of at least 85% of the aggregate principal amount of the Securities outstanding, the Company shall
have the ability by notice to the Trustee to redeem the entire outstanding principal amount of the Securities on the Effective Date at the same price as for the Securities being redeem under this Section. Such notice shall be irrevocable and shall
be given to the Trustee no later than 15 days prior to the Effective Date. Notice of such redemption shall be given to the Holders of the Securities to be redeemed in the manner provided for in the Eleventh Supplemental Indenture. 

The provisions set forth in this Section will not be effective unless and until they are approved substantially in the form provided
herein by a resolution of the general meeting of shareholders of the Parent Guarantor. The Parent Guarantor will procure that a resolution to approve the terms of this Section is presented to the shareholders of the Parent Guarantor at the first
annual general meeting after November 8, 2010 and at each successive annual general meeting of the Parent Guarantor thereafter until such resolution is approved and immediately following approval of such resolution the Parent Guarantor will
cause a copy thereof to be filed with the Clerk of the Commercial Court of Brussels (“greffe du tribunal de commerce/griffie van de rechtbank van koophandel”). The Parent Guarantor will notify the Trustee promptly after each shareholder
meeting of the results of the vote on the proposed resolution. If the general meeting of shareholders of the Parent Guarantor does not approve the provisions set forth in this Section by the date that is eighteen (18) months following the
Original Issue Date, the interest rate applicable to the Securities will increase by 0.25% with effect from the next following day until the date that the Parent Guarantor notifies the Trustee that the provisions of this Section have been approved
(or unless and until such approval is no longer required in order for the Change in Control Clause to be effective), following which the interest rate applicable to the Securities will decrease by the same amount. 

5. Optional Tax Redemption 
 The Company may, at the Company’s or the Parent Guarantor’s option, redeem the Securities in whole, but not in part, upon not less than thirty (30) nor more than sixty (60) days’
prior notice, at a redemption price equal to 100% of the principal amount of the Securities then outstanding plus accrued and unpaid interest on the principal amount being redeemed (and all Additional Amounts, if any) to (but excluding) the
Redemption Date, if (i) as a result of any change in, or amendment to, the laws, treaties, regulations or rulings of a jurisdiction in which the Company or any Guarantor is incorporated, organized, or otherwise tax resident or any political
subdivision or any authority thereof or therein having power to tax, or in the interpretation, application or administration or any such laws, treaties, regulations or rulings (including a holding, judgment or order by

  
 A-7

  
 Exhibit A

  
 
a court of competent jurisdiction) which becomes effective on or after the Original Issue Date (any such change or amendment, a “Change in Tax Law”), the Company or, if a payment
were then due under a Guarantee, the relevant Guarantor, would be required to pay Additional Amounts and (ii) such obligation cannot be avoided by the Company or the relevant Guarantor taking reasonable measures available to it; provided,
however, that the Securities may not be redeemed to the extent such Additional Amounts arise solely as a result of the Company assigning its obligations under the Securities to a Substitute Company, unless such assignment to a Substitute Company is
undertaken as part of a plan of merger by the Parent Guarantor. 
 Prior to the mailing of any notice of redemption pursuant to
this Section, the Company or the relevant Guarantor will deliver to the Trustee an opinion of independent tax counsel of recognized standing to the effect that the Company or the relevant Guarantor is or would be obligated to pay such Additional
Amounts as a result in such Change in Tax Law. 
 No notice of redemption pursuant to this Section may be given earlier that
ninety (90) days prior to the earliest date on which the Company or the relevant Guarantor would be obligated to pay Additional Amounts if a payment in respect of the Securities were then due. 

6. Additional Amounts 
 In the event that any Guarantor becomes obligated to make payments in respect of the Securities, such Guarantor will make all payments in respect of the Securities without withholding or deduction for or
on account of any present or future taxes or duties of whatever nature imposed or levied by way of withholding or deduction at source by or on behalf of any jurisdiction in which such Guarantor is incorporated, organized, or otherwise tax resident
or any political subdivision or any authority thereof or therein having power to tax (the “Relevant Taxing Jurisdiction”) unless such withholding or deduction is required by law. In such event, such Guarantor will pay to the Holders
such additional amounts (the “Additional Amounts”) as shall be necessary in order that the net amounts received by the Holders, after such withholding or deduction, shall equal the respective amounts of principal and interest which
would otherwise have been receivable in the absence of such withholding or deduction; except that no such Additional Amounts shall be payable on account of any taxes or duties which: 

(a) are payable by any person acting as custodian bank or collecting agent on behalf of a Holder, or otherwise in any
manner which does not constitute a deduction or withholding by such Guarantor from payment of principal or interest made by it, or 
 (b) are payable by reason of the Holder or beneficial owner having, or having had, some personal or business connection with such Relevant Taxing Jurisdiction and not merely by reason of the fact that
payments in respect of the Securities or the Guarantees are, or for purposes of taxation are deemed to be, derived from sources in, or are secured in the Relevant Taxing Jurisdiction, or 

  
 A-8

  
 Exhibit A

  
 (c) are imposed or withheld by
reason of the failure of the Holder or beneficial owner to provide certification, information, documents or other evidence concerning the nationality, residence, or identity of the Holder and beneficial owner or to make any valid or timely
declaration or similar claim or satisfy any other reporting requirements relating to such matters, whether required or imposed by statute, treaty, regulation or administrative practice, as a precondition to exemption from, or a reduction in the rate
of withholding or deduction of such taxes, or 
 (d) consist of any estate, inheritance, gift, sales, excise,
transfer, personal property or similar taxes, or 
 (e) are imposed on or with respect to any payment by the
applicable Guarantor to the registered Holder if such Holder is a fiduciary or partnership or any person other than the sole beneficial owner of such payment to the extent that taxes would not have been imposed on such payment had such registered
Holder been the sole beneficial owner of this Security, or 
 (f) are deducted or withheld pursuant to
(i) any European Union directive or regulation concerning the taxation of interest income, or (ii) any international treaty or understanding relating to such taxation and to which the Relevant Taxing Jurisdiction or the European Union is a
party, or (iii) any provision of law implementing, or complying with, or introduced to conform with, such directive, regulation, treaty or understanding, or 

(g) are payable by reason of a change in law or practice that becomes effective more than 30 days after the relevant
payment of principal or interest becomes due, or is duly provided for and written notice thereof is provided to the Holders, whichever occurs later, or 
 (h) are payable because any Security was presented to a particular paying agent for payment if the Security could have been presented to another paying agent without any such withholding or deduction, or

 (i) are payable for any combination of (a) through (h) above. 

References to principal or interest in respect of the Securities shall be deemed to include any Additional Amounts which may be payable
as set forth in the Indenture. 
 The covenant regarding Additional Amounts shall not apply to any Guarantor at any time when
such Guarantor is incorporated in a jurisdiction in the United States, and will apply to the Company any time it is incorporated in a jurisdiction outside of the United States. 

  
 A-9

  
 Exhibit A

  
 7. Transfer and Exchange 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the
Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by
a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like
tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
 As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like
tenor of a different authorized denomination, as requested by the Holder surrendering the same. 
 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 other governmental charge payable in connection therewith. 

Prior to due presentment of this Security for registration of transfer, the Company, the Guarantors, the Trustee and any agent of the
Company, the Guarantors or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Guarantors, the Trustee nor any such
agent shall be affected by notice to the contrary. 
 8. Default 

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any
proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to
the Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default
as Trustee and offered the Trustee indemnity and/or security, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request,
and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity and/or security. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement
of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein. 

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed. 

  
 A-10

  
 Exhibit A

  
 9. Amendment, Modification and Waiver

 The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights
and obligations of the Company or the Guarantors and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal
amount of the Securities at the time Outstanding (irrespective of series) that are to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the
time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company and the Guarantors with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any
such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu
hereof, whether or not notation of such consent or waiver is made upon this Security. 
 10. Defeasance 

The Indenture contains provisions for defeasance at any time of certain restrictive covenants and Events of Default with respect to this
Security upon compliance with certain conditions set forth in the Indenture. 
 11. Governing Law 

This Security shall be governed by and construed in accordance with the laws of the State of New York. 

12. Defined Terms

	3.7	Lead Times 

  

	 	3.7.1	Spare Parts for Initial Provisioning shall be delivered on or before the dates specified in Spirit’s orders, provided that the dates comply with Lead Times and do

anticipated total requirement of pre-modified Spare Parts, at a price and delivery schedule to be agreed. 

  

	 	3.9.3	Unless Spirit notifies IAE in writing under the provisions of Clause 3.9.2 hereof IAE may supply at the expense of Spirit a modification of any Spare Part ordered

	4.1	IAE warrants to Spirit that, at the time of delivery to Spirit, the Supplies delivered will be free of defects in material and manufacture, and will conform to
applicable specifications and the rules and regulations of the Certification Authority. IAE’s liability and Spirit’s remedies under this warranty are limited to the repair or replacement, at IAE’s election, of Supplies or parts
thereof returned to IAE at the factory of manufacture which are shown to IAE’s reasonable satisfaction to have been defective; provided, that written notice of the defect shall have been given by Spirit to IAE within ninety (90) days after
the first operation or use of the Supplies (or if the Supplies are installed in Spirit Aircraft, within ninety (90) days after acceptance of such Aircraft by its operator) but in no event later than one (1) year (except in the case of
tools which shall be two (2) years unless otherwise limited by the tool manufacturer’s warranty) after the date of delivery of such Supplies by IAE. Transportation charges for the return of Supplies to IAE pursuant to this Clause 4.1 and
their reshipment to Spirit and the risk of loss thereof will be borne by IAE only if the Supplies are returned in accordance with written shipping instructions from IAE and continued by IAE acting reasonably to have been defective at the time of
delivery to Spirit. 

  

	4.2	In addition, IAE grants and Spirit accepts the following: 

 ***** 
 ***** Confidential portions of the material have been omitted and filed separately with
the Securities and Exchange Commission. 

  
 Page 17 of 28

  
 The Service Policies, Warranties and
Guarantees referred to in this Clause 4.2 are hereinafter called the “Warranties”. The above Service Policies, Warranties and Guarantees together form Exhibit D to this Contract. 

 

	4.3	The parties agree that those of the Warranties set out in Clauses 4.2.1 and 4.2.2 above shall apply to any equipment specified in those Warranties, which are
manufactured, supplied or inspected by IAE howsoever and whenever (whether before, on or after the date first above written) acquired by Spirit from whatsoever source including but not limited to any V2500 aero engines and any associated equipment
therefor, and any parts for such engines and associated equipment which form part of any Aircraft. 

  

	4.4	The Warranties are personal to Spirit and the obligations of IAE thereunder shall only apply insofar as Spirit owns and operates the Supplies covered thereunder.
Notwithstanding the foregoing, Spirit shall have the right to assign its rights under (i) the V2500 Engine and Parts Service Policy, (ii) the V2500 Nacelle and Parts Service Policy and (iii) the Non-Installation Items Warranty to any
person or entity in connection with any leasing, subleasing, financing or re-financing arrangement or to any Affiliate, with IAE’s consent, not to be unreasonably withheld or delayed. Spirit must at all times continue to be the operator and/ or
owner of such Engines. The actual terms of any assignment will be agreed by Spirit and IAE. Any assignment made in violation of this Clause 4.4 or if Spirit ceases to operate or own the Engines shall cause any such assignment to be null and void.
“Affiliate” shall mean, as applied to any person or entity, any other person or entity directly or indirectly controlled by, controlling or under common control with such person or entity. 

 

	4.5	Spirit shall inform any entity to whom it intends to sell, lease, loan or otherwise dispose of any of the Supplies or equipment referred to in Clause 4.3 above that
such entity may request from IAE a direct warranty agreement incorporating those of the Warranties set out in Clauses 4.2.1 and 4.2.2. Spirit shall also use its reasonable endeavors to ensure that such entity shall enter into a direct warranty
agreement with IAE prior to delivery of any of the Supplies or such equipment to such entity. 

  

	4.6	IAE and Spirit agree that the intent of the Warranties provided in Clause 4.2 is to provide specified benefits or remedies to Spirit as a result of specified events. It
is not the intent, however, to duplicate benefits or remedies provided to Spirit by IAE or another source (e.g., another equipment manufacturer or lessor) as a result of the same event or cause. Therefore, notwithstanding the terms of the
Warranties, Spirit agrees that it shall not be eligible to receive benefits or remedies from IAE if it stands to receive or has received duplicate benefits or remedies from IAE or another source as a result of the same event or cause. Furthermore,
in no event shall IAE be required to provide duplicate benefits to Spirit and any other party such as a leasing company as a result of the same event or cause. 

 

	4.7	 Spirit accepts that the Warranties granted to Spirit under Clauses 4.1, 4.2 and 4.3 above together with the express remedies provided to Spirit in
respect of the Supplies in accordance with this Contract are expressly in lieu of, and Spirit hereby waives, all other remedies, conditions and warranties, expressed or implied including without limitation,

  
 Page 18 of 28

	 	 
ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, and all other obligations and liabilities whatsoever of IAE and of its shareholders whether in contract or in tort
or otherwise for any defect, deficiency, failure, malfunctioning or failure to function of any item of the Supplies or of the equipment referred to in Clause 4.3 above, howsoever and whenever acquired by Spirit from whatever sources. Spirit agrees
that neither IAE nor any of its shareholders shall be liable to Spirit upon any claim therefore or upon any claim howsoever arising out of the manufacture or supply or inspection by IAE or any of its shareholders of any item of the Supplies or of
such equipment or any other item of whatever nature, whether in contract or in tort or otherwise, except as expressly provided in the Warranties described herein. 

 

	4.8	IAE and Spirit agree that this Clause 4 has been the subject of discussion and negotiation, is fully understood by the parties and the price of the Supplies and other
mutual agreements of the parties set forth in this Contract are arrived at in consideration of: 

  

	 	4.8.1	the express Warranties of IAE and Spirit’s rights thereunder; and 

  

	 	4.8.2	the exclusions, waivers and limitations set forth in Clause 4.7 above. 

 CLAUSE 5 PRODUCT SUPPORT SERVICES 
  

	5.1	IAE will make available to Spirit the Product Support Services described in Exhibit C to this Contract. Except when identified in such Exhibit C as being at additional
cost or as requiring separate contractual arrangements, such Product Support Services shall be supplied at no additional charge to Spirit and subject to the provisions of this Contract. IAE may delegate the performance of product support services to
an affiliated company or any of IAE’s shareholders. 

  

	5.2	Spirit will provide to any IAE customer support representative(s) working at its facility, free of charge: 

 

	 	(a)	reasonable, secure office accommodation including furniture and office equipment; 

 

	 	(b)	access to telephone, facsimile and secretarial services; and 

  

	 	(c)	access to such first-aid and emergency assistance as is customarily provided to Spirit’s own employees; 

 

	 	(d)	reasonable airfare, accommodations, and subsistence during any period in which the customer support representative(s) is required by Spirit to travel away from such
customer support representative(s)’ normal location at Spirit. 

 Spirit further agrees and acknowledges that
such customer support representatives shall at all times remain employees of IAE and shall, in such capacity, be entitled to reasonable working benefits such as leaves of absence, sick days and holidays as are paid for and

  
 Page 19 of 28

 
granted by IAE to its employees. However, such leaves shall not interfere with IAE’s provision of the Product Support Services to Spirit, and should any leave for a customer support
representative extend beyond forty-five (45) days IAE agrees to provide a substitute representative to ensure continuity of service. Notwithstanding the foregoing, at no time shall any IAE customer support representative be considered an
employee or independent contractor of Spirit.

	 	6.1.1	If IAE is hindered or prevented from performing any obligation hereunder including but not limited to delivering any of the Supplies within the time for delivery
specified in this Contract (as such time may be extended pursuant to the provisions of this Contract) by reason of: 

  

	 	6.1.1.1	any cause beyond the reasonable control of IAE, or 

  

	 	6.1.1.2	fires, industrial disputes or introduction of modifications required by the Certification Authority 

(any such delay an “Excusable Delay”) the time for delivery shall be extended by a period equal to the period for which
delivery shall have been so hindered or prevented, and IAE shall not be under any liability whatsoever in respect of such delay. 
  

	 	6.1.2	If, by reason of any of the Excusable Delays embraced by Clause 6.1.1 above, IAE is hindered or prevented from delivering any goods (which are the same as and include
the Supplies) to purchasers (including Spirit) then IAE shall have the right to allocate in good faith such goods, as they become available, at its own discretion among all such purchasers and IAE shall not be under any liability whatsoever to
Spirit for delay in delivery to Spirit resulting from such allocation by IAE and the time for delivery shall be extended by a period equal to the delay resulting from such allocation by IAE. Notwithstanding the foregoing, should the delivery to
Spirit of any Installation Item be delayed more than ***** due to an Excusable Delay, Spirit may terminate the order with respect to the affected Installation Item by giving prior written notice to IAE. Upon receipt of such notice, both Spirit and
IAE shall be free from any obligations in respect of such Installation Item except that IAE shall refund to Spirit any deposits made in respect of the purchase price of such Installation Item. 

 

	 	6.1.3	Should IAE inexcusably delay performance of any obligation hereunder including but not limited to delivery of any item of the Supplies beyond the time for delivery

 Page 20 of 28

	 	 
Spirit’s sole remedy shall be its reasonable actual damages in an amount not to exceed ***** of the purchase price of the item of Supplies so delayed in respect of each month of such further
delay (and pro rata for any period of less than one month) subject to an overall maximum of ***** of the purchase price of the item of the Supplies so delayed. 

 

	 	6.1.4	The right of Spirit to claim damages shall be conditional upon Spirit: 

  

	 	(i)	notifying IAE of the existence of its claim in writing within sixty (60) days from the Claim Start Date, and 

 

	 	(ii)	submitting a written claim therefore within ninety (90) days from the Claim Start Date. 

The “Claim Start Date” shall be the date on which IAE notifies Spirit that the item of the Supplies so delayed is ready for
delivery, or from the date on which Spirit exercises the right of cancellation in respect of such item conferred in accordance with Clause 6.1.5 below, whichever date shall first occur. 

 

	 	6.1.5	Should IAE inexcusably delay performance of any obligation hereunder including but not limited to delivery of any item of the Supplies beyond ***** from the time for
delivery specified in this Contract (as such time may be modified pursuant to the provisions of the Aircraft Purchase Agreement, or any of the ILFC Leases or leases for the Additional Leased Aircraft, as applicable and as notified to IAE) then, in
addition to the right of Spirit under Clause 6.1.3, Spirit shall be entitled to terminate the order with respect to the affected item on giving IAE notice in writing. Upon receipt of such notice both Spirit and IAE shall be free from any obligation
in respect of such item except that IAE shall refund to Spirit any deposits made in respect of the purchase price of such item of the Supplies. 

  

	6.2	Patents 

  

	 	6.2.1	IAE shall, subject to the conditions set out in this Clause and as the sole liability of IAE in respect of any claims for infringement of industrial property rights,
indemnify and hold Spirit harmless from and against any damages, costs and expenses including legal costs resulting from any claim that the use of any of the Supplies by Spirit within any country to which at the date of such claim the benefits of
Article 27 of the Convention on International Civil Aviation of 7th December 1944 (The Chicago Convention) or the International Convention for the Protection of Industrial Property of March 20, 1883 (the Paris Convention) apply, infringes
any patent, design, or model duly granted or registered provided, however, that IAE shall not be liable to Spirit for any consequential damage or any loss of use of the Supplies or of the Aircraft in which the Supplies may be incorporated arising as
a result directly or indirectly of any such claim. 

 ***** Confidential portions of the material have been omitted and filed
separately with the Securities and Exchange Commission. 

  
 Page 21 of 28

  

	 	6.2.2	Spirit will give prompt notice in writing to IAE of any such claim whereupon IAE shall have the right at its own expense to assume the defense of or to dispose of or to
settle such claim in its sole reasonable discretion and Spirit will give IAE all reasonable assistance and will not by any act or omission directly or indirectly prejudice IAE in this connection. IAE shall reimburse Spirit for its reasonable
expenses incurred in providing any such assistance. 

  

	 	6.2.3	IAE shall have the right to substitute for any allegedly infringing Supplies substantially equivalent non-infringing supplies. 

 

	 	6.2.4	Should Spirit be prevented from using any of the Supplies due to a claim of infringement of property rights by valid judgment or by settlement between Spirit, IAE and
the claimant IAE will, at its expense as soon as possible but in no event more than ninety (90) days from the date of entry of such judgment or settlement either (a) obtain for Spirit the right to use the respective Supply or Supplies free
of charge or (b) replace the respective Supply or Supplies with a substantially equivalent non-infringing substitute, if available. 

  

	 	6.2.5	The indemnity contained in Clause 6.2.1 above shall not apply to claims for infringement in respect of (i) Supplies manufactured to the specific design
instructions of Spirit; (ii) Supplies not of IAE design (but IAE shall in the event of any claim for infringement pass on to Spirit so far as it has the right to do so the benefits of any indemnity given to IAE by the designer, manufacturer or
supplier of such Supplies); (iii) the manner or method in which any of the Supplies is installed in the Aircraft; or (iv) any combination of any of the Supplies with any item or items other than Supplies. 

 

	6.3	Credit Reimbursement and Assignment. 

  

	 	6.3.1	If Spirit does not take delivery of the Purchased Aircraft (each Purchased Aircraft, a “Firm Item”) then, without prejudice to IAE’s other rights and
remedies under the Contract or otherwise, the value of each and every credit, benefit and other concession received by Spirit pursuant to the Contract (including all Side Letters and amendments thereto) or from IAE via the Aircraft Manufacturer will
be adjusted to pro-rata amounts, based on the ratio of the number of Firm Items purchased in accordance with the schedules described in Exhibit B-1 to the Contract to the total number of Firm Items scheduled to have been so purchased. So, for
example, if IAE is to issue credits on delivery of each Finn Item and Spirit takes delivery of only half the total number of such Firm Items (whether or not with the consent of the Aircraft Manufacturer) the value of each credit to be issued on the
Firm Items actually taken and all other credits (if any) will be reduced by half. Following such adjustment, Spirit will promptly reimburse IAE in an amount equal to *****

	 	6.4.4	Each party shall be responsible for obtaining its own respective required authorizations including any export licenses, import licenses, exchange permits or any other

 IAE ESCALATION FORMULA 

 

	1.	Any unit base price or other sum expressed to be subject to escalation from a base month to a month of delivery or other date of determination in accordance with the
IAE Escalation Formula will be subject to escalation in accordance with the following formula: 

 *****

 ***** 
 The quarterly value published for the Employment Cost Index will be deemed to apply to each month of the quarter. 
 The Labor Ratio is the “Employment Cost Index (ECI) Wages and Salaries for Aircraft Manufacturing, SIC Code 3721” as published by the Bureau of Labor Statistics, U.S. Department of Labor for the
arithmetic average of the fifth, sixth and seventh months (rounded to the nearest tenth) preceding the month of scheduled delivery; divided by the value of SIC Code 3721 for the arithmetic average of the fifth, sixth and seventh months (rounded to
the nearest tenth) preceding the base month. 
 The Material Ratio is the “Producer Price Indexes, Industrial
Commodities”, as published by the Bureau of Labor Statistics, U.S. Department of Labor, for the arithmetic average of the fifth, sixth and seventh months (rounded to the nearest tenth) preceding the month of scheduled delivery; divided by the
value for Industrial Commodities for the arithmetic average of the fifth, sixth and seventh months (rounded to the nearest tenth) preceding the base month. 
 ***** Confidential portions of the material have been omitted and filed separately with the Securities and Exchange Commission.

	2.	If the U.S. Department of Labor changes the base year for determination of the Index values as defined above or revises the methodology used for the determination of
the values to be used to determine the CPI or, for any reason, has not released values needed to determine the CPI, IAE, in its sole discretion, shall select a substitute for such values from data published by the Bureau of Labor Statistics or
otherwise make revisions to the escalation formula such that the escalation will as closely as possible approximate the result that would have been attained by continuing the use of the original escalation formula and values as they may have
fluctuated during the applicable time period. 

  

	3.	The invoiced purchase price or final escalated sum, which in no event shall be less than the unit base price, shall be the final price or final escalated sum.

accurate requirements planning. In support of the requirements planning effort, a wide ranging data retrieval and analysis program shall be offered. This program shall concern itself both with the customer logistics and technical considerations as
follows: 
  

	 	–	Forecasts of life limited parts requirements are requested and received semi-annually from major customers. Based on the size of Spirit’s order, Spirit shall be
considered a major customer. 

  

	 	–	Engine technical conferences are held frequently within IAE to assess the impact of technical problems on parts. 

 

	 	–	For a selected group of parts a provisioning conference system is offered which considers actual part inventory change, including usage and receipts, as reported
monthly by participating customers. 

  

	 	5.1.5	Packaging 

 All material
shall be packaged in general compliance with Air Transport Association of America (ATA) Specification No. 300.

	Subject:	Side Letter No. 4 to the V2500-A5 General Terms of Sale between IAE International Aero Engines AG and Spirit Airlines, Inc., dated March 1, 2005

 Dear Mr. Shallcross: 
 We refer to the V2500-A5 General Terms of Sale dated March 1, 2005 (the “GTA”) between IAE International Aero Engines AG (“IAE”) and Spirit Airlines, Inc. (“Spirit”),
such contract being hereinafter referred to as the “Contract.” Unless expressly stated to the contrary, and to the extent possible, terms used in this Side Letter No. 4 shall have the same meaning given to them in the Contract, as
modified by Side Letters No. 1, No. 2, and No. 3 to the Contract. 
 This Side Letter No. 4 provides for, among other
things, the exercise of option aircraft, the conversion from A319 Aircraft to A320 or A321 Aircraft, additional delay rights for Spirit, and spare parts purchase terms. 

 

	1.	OPTION AIRCRAFT 

  

	1.1	Option Exercise 

 1.1.1 IAE acknowledges
that AVSA S.A.R.L and Airbus (collectively, “Airbus”) have granted Spirit the right to purchase up to ***** new IAE powered A319 Aircraft (the “Option Aircraft”) for delivery in the following delivery quarters: 

 

									
	 1.1.2
	  	 Delivery
	  	 # of Option Aircraft
	  	 Delivery
	  	 # of Option Aircraft

		  	*****	  	*****	  	*****	  	*****

 1.1.3 The foregoing delivery
quarters, which IAE agrees to support based on the terms and conditions in this Side Letter and the Contract, are provisional and will remain subject to prior sale and Airbus’s commercial and industrial constraints until the relevant Option
Aircraft is converted into a firm order for an A319 Aircraft. 
 ***** Confidential portions of the material have been omitted and filed
separately with the Securities and Exchange Commission. 

  
 [Page 1 of 4]

 1.1.4 If agreed by Airbus, Spirit may reserve any of the delivery positions described in Paragraph 1.1.2 of
this Side Letter No. 4 in respect of up to ***** Option Aircraft (which Option Aircraft will then become the “Reserved Option Aircraft”), provided that such delivery positions have not already been sold by Airbus to another customer.
At the time of exercise and in respect of any Reserved Option Aircraft, subject to Airbus’ commercial and industrial constraints at the time, and after Spirit’s written request to Airbus with a copy to IAE, upon Airbus’ written
consent, IAE will consent to, delivery quarters other than as may be reserved pursuant to this Paragraph 1.1.4. 
 1.1.5 Right to Firm-Up
Option and Reserved Option Aircraft. Spirit may exercise its right to convert an Option Aircraft or Reserved Option Aircraft into a firm Purchased A319 Aircraft, no later than ***** months before the first day of the first month of the relevant
delivery quarter (the “Latest Option Exercise Date”) of each such Option Aircraft. 
 1.1.6 Spirit will convert Option Aircraft and or
Reserved Option Aircraft into a firm Purchased A319 Aircraft by written notice to Airbus and IAE. Upon confirmation and agreement from Airbus and timely notice to IAE of the same to allow the conversion, IAE will consent to such conversion.

 1.1.7 Any Option Aircraft or Reserved Option Aircraft not converted into a firm order by the Latest Option Exercise Date shall automatically
expire and Spirit and IAE shall have no further rights and obligations with respect to such Option Aircraft or Reserved Option Aircraft. 
  

	2.	ROLLING OPTION AIRCRAFT 

 2.1 IAE
acknowledges that Airbus will grant Spirit ***** additional option aircraft for each Option Aircraft and/or Reserved Option Aircraft which is converted into a firm order (the “Rolling Option Aircraft”) and IAE agrees to provide propulsion
systems for the same on the terms contained herein. 
 2.2 Each such Rolling Option Aircraft will be subject to the same terms and conditions as
the Option Aircraft except that: 
 (i) Rolling Option Aircraft shall not have reserved delivery positions assigned thereto; 

(ii) Deliveries shall be subject to agreement between Spirit and Airbus, with notice to IAE, and shall be subject to Airbus’s commercial and
industrial constraints; 
 (iii) The delivery date in respect of any Rolling Option Aircraft shall not be scheduled later than the *****;

 (iv) Any Rolling Option Aircraft not converted into a firm order by ***** will automatically expire and the parties will have no further
rights and obligations to one another with respect to the expired Rolling Option Aircraft; and 
 (v) The maximum number of Aircraft that
may be scheduled for delivery in any one (1) quarter is ***** 
  

	3.	CONVERSION AIRCRAFT  

 *****

 3.3 The conversion rights pursuant to this paragraph 3 shall also be applicable with respect to any Option Aircraft converted to a firm A319
Aircraft pursuant to the provisions of Paragraph 1 above, provided that the conversion is concluded not later than ***** months prior to delivery of the relevant Option Aircraft so converted to a firm A319 Aircraft.

	4.	FLEET INTRODUCTORY ASSISTANCE CREDIT WITH RESPECT TO OPTION AIRCRAFT AND CONVERSION AIRCRAFT; FURTHER CONDITIONS  

4.1 If Spirit exercises its right to convert Aircraft to a different model type as allowed by this Side Letter No. 4, IAE shall provide the
corresponding Fleet Introductory Assistance (“FIA”) in Side Letter No. 1 to the Contract to the model type to which Spirit converts. For instance, if Spirit converts from an A319 to an A320 Aircraft, IAE will increase the FIA from
A319 levels to A320 levels. 
 4.2 IAE’s agreement to provide the rights in Clause 1 to 4 of this Side Letter are conditional on the terms
and conditions herein. Airbus actually providing such rights to Spirit, and Spirit not being in default of its obligations to IAE or Airbus. 
  

	5.	AIRCRAFT DELIVERY DELAYS 

 5.1 If
Spirit fails to take delivery of said Aircraft in accordance with the delivery schedule in Exhibit B-1 to the Contract (or as otherwise rescheduled pursuant to this Side Letter No. 4 or written agreement between IAE and Spirit) and such failure
is by reason of: 
 5.1.1 any delay that is due to (i) an Airbus caused delay not requested by Spirit or caused by
Spirit’s inability to take the Aircraft, or (ii) fires, floods, or other acts of God, riots, insurrection, war, labor disputes, or terrorist attacks (a “Delivery Delay”). For the avoidance of doubt, a Delivery Delay would include
an aircraft delay caused by IAE. 
 In the event of such Delivery Delay, IAE agrees that the time for delivery shall be extended by a period
equal to the period for which delivery shall have been so hindered or prevented, and Spirit shall not be under any liability whatsoever in respect of such delay for up to ***** months. After the ***** month period of delay, IAE reserves the right to
modify the rates for the warranties listed in Exhibit D-1 and D-2 (as enhanced by Side Letter No. 2 to the Contract), the guarantees listed on Exhibits D-5 to D-12 and in Side Letter No. 3 to the Contract, and the Fleet Hour Agreement.

 5.2 Notwithstanding the foregoing, should the Aircraft delivery be delayed more than ***** months due to a Delivery Delay, IAE may any time
thereafter terminate the order with respect to the Installation Items for the affected Aircraft so delayed or consider such Aircraft cancelled by Spirit, by giving prior written notice to Spirit. Upon receipt of such notice, both Spirit and IAE
shall be free from any obligations as between each other in respect of the Installation Items for the affected Aircraft so delayed. 
  

	6.	SPARE PARTS PURCHASE OBLIGATIONS 

IAE and Spirit recognize that Spirit will be purchasing Spare Parts from ***** or another supplier of Spare Parts mutually agreeable to IAE and Spirit
(“Approved Spare Parts Source”). As such, to the extent Spirit purchases Spare Parts from an Approved Spare Parts Source, Clause 3.14 of the Contract entitled “Purchase by Spirit from Others” shall not apply.

	7.	ASSIGNMENT 

 Notwithstanding any
other provision of this Side Letter No. 4 or of the Contract, this Side Letter and the rights and obligations of Spirit hereunder will not be assigned or transferred in any manner without the prior written consent of IAE, and any attempted
assignment or transfer in contravention of the provisions of this Paragraph 6 will be void and of no force or effect. 
  

	8.	COUNTERPARTS 

 This Side Letter
No. 4 may be executed by the parties hereto in separate counterparts, each of which when so executed and delivered shall be an original, but all such counterparts shall together constitute one and the same instrument. 

Except as expressly amended by this Side Letter No. 4, all provisions of the Contract remain in full force and effect.
