 Likewise, the Borrower also unconditionally promises to pay the Lender, without prior request, ordinary interests over
the unpaid Principal Sum during each Interest Period due (as this term is defined herein) since the date of this Promissory Note and until the Expiration Date, on an annual rate equivalent to the Ordinary Interest Rate (as this term is defined
herein). 

  
 53 

 Interests will be due quarterly on the last day of each Period of Interests; in the understanding that, in
case such day is not a Business Day, such payment shall be made on the next Business Day (each one an “Interest Payment Date”); in the understanding that the last Interest Payment Day shall occur precisely on the Expiration
Date. 
 In case of an event of default concerning the payment of any amount due under this Note (except for ordinary interest) default interest
will generate over the due and unpaid amount, beginning on the date in which such amount should have been paid until it is paid in full, at an annual interest rate of 1.25 (one point twenty five) times the Ordinary Interest Rate applicable during
the period in which the default occurs and continues (the “Default Interest Rate”). 
 If any Payment Date or any Interest
Payment Date occurs on a day which is not a Business day, such payment shall be made on the next Business Day. 
 Ordinary Interest hereunder
shall be calculated on the basis of the actual number of days elapsed divided by 360 (three hundred sixty), including the first day but excluding the last day of the corresponding calculation period. 

Default Interest due under this Note shall be calculated by dividing the Default Interest Rate applicable by three hundred sixty (360) and the
result will be applied to the amounts due and unpaid, the result will be the default interest of each day that the Borrower agrees to pay on demand according to this Promissory Note. 
 For purposes of this Promissory Note, the following terms shall have the following meanings: 

“Business Day” means any day in which the banking institutions in Mexico are not authorized to be closed. 

“Dollars” or “$” means the legal currency of the United States of America. 

“Interest Period” means, for the first interest period, the period that begins on the date of this Promissory Note and ends on the
Payment Date, and for each subsequent period, the period that begins the last day of the Interest Period next succeeding and that concludes on the next Payment Date. 
 “Ordinary Interest Rate” means, a rate equivalent to the LIBOR rate plus a margin of 265 (two hundred and sixty five) base points. 

The Borrower will makes all payments of principal, interest, commissions and any other amount due under this Promissory Note free of interest,
contributions, withholdings, deductions, fees or any other fiscal responsibility due under the laws, regulations and 

  
 54 

 
other applicable legal dispositions in the United Mexican States, without any compensation, in immediately available funds, before 12:00PM (Mexico City, Federal District, United Mexican States)
of the day in which the amount concerning becomes due. All payments made by the Borrower according to this Promissory Note shall be made in Dollars, through the account held between the Borrower and Banco Santander (México), S.A.
Institución de Banca Múltiple, Grupo Financiero Santander. 
 The Borrower agrees to repay upon demand, in the same way and using
the same funds, any costs and reasonable and duly justified amounts incurred in relation to the compliance or execution of this Promissory Note (including, without limitation, all documented legal costs). 

The Borrower hereby waives any judicial proceedings, file, presentation, notice or lawsuit of any nature en relation to this Promissory Note. 

Pursuant to Article 128 of the General Law of Credit Instruments of the United Mexican States, the period of presentment of this Promissory Note is
hereby irrevocably extended until the date that is 6 (six) months after its Expiry Date; provided, however, that such extension does not imply that this Promissory Note cannot be presented for payment at an earlier date. 

This Promissory Note shall be governed and interpreted according to the laws of the United Mexican States. 

Concerning everything related to this Promissory Note, the Trustee hereby irrevocably submits to the jurisdiction of the courts of Mexico City, federal

Subsidiaries, shall be deemed to constitute any representation or warranty by the Agent to any Lender as to any matter, including whether the Agent has disclosed material information in its possession. Each Lender represents to the Agent that it

and hold the Agent harmless from and against any and all liabilities derived from his role as Agent, included consequences due to error or omission; provided, however, that no Lender shall be liable for the payment to the Agent of any
portion of such Indemnified Liabilities to the extent determined in a final judgment by a court of competent jurisdiction to have resulted from the Agent’s gross negligence or willful misconduct. Without limitation of the foregoing, each Lender
shall reimburse the Agent upon demand for its ratable share of any costs or out-of-pocket expenses (including Attorney Costs) incurred by the Agent in connection with the preparation, execution, delivery, modification, amendment or enforcement

that the Agent is not reimbursed for such expenses by or on behalf of the Borrowers. The Lenders also agree to reimburse the Agent, in advance, for any documented taxes required to be paid by the Agent pursuant to this Agreement. The undertakings in
this Section shall survive the payment of all other Obligations and the resignation or removal of the Agent. 
 (h) Agent
acting on behalf of the Lenders. Santander and Bancomext agree and acknowledge that a consent obtained from both of the Lenders shall be required in order for the Agent to perform any other act or omission which may result in affecting any of
the Lenders’ rights under this Agreement, in the understanding that the Agent shall not agree in any modification to the term, amount, rate or any other related to the Credit, without Bancomext’s consent . Consequently, the Lenders hereto
acknowledge and agree that any action taken by the Lenders against the Borrower and the Joint Obligors pursuant to this Agreement, shall always be initiated collectively by all of the Lenders, in the understanding that the Agent does not assumes any
liability of any nature in connection with such actions. 
 Santander and Bancomext agree that in the event that the Agent
receives any amount derived from an action taken by him, with the unanimous consent of the Lenders, such amounts shall be distributed evenly by Santander and Bancomext in respect to Bancomext’s Portion and Santander’s Portion hereunder.

Santander or its Affiliates may receive information regarding the Borrowers or any of its Affiliates (including information that may be subject to confidentiality obligations in favor of the Borrowers or such Affiliate) and acknowledge that the
Agent shall be under no obligation to provide such information to them. With respect to the A Tranche Santander’s Portion and the B Tranche Santander’s Portion, Santander shall have the same rights and powers under this Agreement as any
other Lender and may exercise such rights and powers as though it were not an Affiliate of the Agent, and the terms “Lender” and “Lenders” include Santander in its individual capacity.

Lenders, which successor agent shall be subject to the prior approval of the Borrowers at all times other than during the existence of an Event of Default (which consent of the Borrowers shall not be unreasonably withheld or delayed). If no
successor agent is appointed prior to the effective date of the resignation of the relevant existing Agent or the Lenders’ election to remove such existing Agent, then such existing Agent may appoint, after consulting with the Lenders and the
Borrowers, a successor agent from among the Lenders. Upon the acceptance of its appointment as the successor agent hereunder, such successor agent shall thereupon succeed to and become vested with all the rights, powers and duties of the retiring
Agent, such retiring Administrative Agent’s appointment, powers and duties as Agent shall be terminated, and the term “Agent” shall mean such successor agent. After the Agent’s resignation or removal hereunder as Agent, the
provisions of this section shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement. If no successor agent has accepted appointment as Agent by the date which is thirty (30) days

request from such Lender without receiving an answer from the Borrower and by the Joint Obligors, it shall be construed as granted by them). Likewise, such Lender may assign, discount, endorse or in any way transfer, totally or partially, their

 MASTER AGREEMENT

 This Master Agreement (the “Agreement”) is made and entered into effective as of July 20, 2009 (“Effective
Date”) by and between Concesionaria Vuela Compañía de Aviación, S.A. de C.V. (d/b/a. Volaris), a company duly organized and existing under the laws of the United Mexican States (“Mexico”), whose address is
Avenida Prolongación Paseo de la Reforma 490, Piso 1 Col. Santa Fe Peña Blanca 01210, Mexico , (“Customer”) and Sabre Inc., a Delaware corporation located at 3150 Sabre Drive, Southlake, TX 76092
(“Sabre”). 
 The terms of this Agreement shall apply to each Work Order and to all System(s) and Services provided to Customer
by Sabre hereunder. The terms and conditions set forth in this Agreement and in any Work Order shall control if there are different or additional terms in any Customer purchase order form or Sabre’s acceptance form or invoice. In the event of a
conflict between the terms and conditions of the Agreement and any Work Order, the Work Order shall supersede the Agreement only for the engagement covered under the specific Work Order. 

 

 1. Definitions. For purposes of this Agreement, certain defined terms will have the meanings
set forth in Exhibit A to this Agreement. 
 2. Term and Termination. 

a) Term. This Agreement will commence as of the Effective Date and continue until the later of (i) five (5) years following the Effective
Date, or (ii) the expiration of all Work Orders to this Agreement. 
 b) Termination. Either party may terminate any Work Order
under this Agreement if the other party commits a Material Breach of the Work Order and fails to cure such Material Breach within thirty (30) days following receipt of written notice from the non-breaching party describing the breach in detail
(except for a breach regarding failure to pay amounts due, in which case the period to cure shall be thirty (30) days). Sabre may terminate this Agreement and/or any Work Order if Sabre has given Customer written notice of a default in payment
of any undisputed amounts due and payable more than three (3) times in any twelve (12) month period during the term. Notwithstanding the above, if the Material Breach cannot reasonably be cured within a thirty (30) day cure period,
the non-breaching party’s right to terminate will not be permitted so long as the breaching party (i) provides a written remediation plan to the non-breaching party prior to the expiration of the thirty (30) day cure period; and
(ii) starts the remediation process as set forth in the plan during the thirty (30) day cure period; and (iii) completes the remediation within sixty (60) days from the date of the original default notice. In addition to all
other remedies, upon written notice to Customer as set forth in Section 9(g) below, Sabre shall also have the right to suspend Customer’s access to any System or any Service without terminating this Agreement or any related Work
Order if Customer fails to pay an undisputed sum for a period in excess of thirty (30) days after it becomes payable.

 c) Early Termination. Sabre and Customer agree that each Work Order will contain and define
provisions regarding early termination. The terms and conditions for early termination will be set forth in each Work Order to this Agreement. 

d) Effects of Termination. Upon the expiration or termination of this Agreement or any Work Order, unless provided otherwise in a Work Order, all
license or access rights granted therein will immediately cease to exist, Customer shall promptly discontinue all use of the System(s), erase all copies of the System(s) from Customer’s computers, and return to Sabre all copies of the
System(s), Documentation, and any other Sabre Confidential Information in Customer’s possession or control, and have an officer of Customer certify to Sabre in writing that it has fully complied with these requirements, except that Customer may
retain a copy of such information if it is required by law and consistent with its record retention policies so long as Customer holds such Confidential Information in confidence in accordance with Section 7 below. Sabre shall return all
Customer’s Confidential Information to Customer to Sabre, and have an officer of Sabre certify to Customer in writing that it has fully complied with these requirements, except that Sabre may retain a copy of such information if it is required
by law and consistent with its record retention policies so long as Sabre holds such Confidential Information in confidence in accordance with Section 7 below. 
 3. Fees and Payment. 
 a) Fees. Customer shall pay Sabre the fees and charges
set forth in the Work Orders to this Agreement. 
 b) Travel and Out-of-Pocket Expenses. Customer shall reimburse Sabre for all
reasonable and pre-approved in writing Project related travel and incidental (T&I) out-of-pocket expenses incurred by

 

  

			
	Sabre Inc. — Confidential	 	1

 
Sabre in connection with this Work Order. Customer will provide Sabre with confirmed coach class travel within its network for Sabre employees conducting the work under this Agreement. If travel
is not possible or available on Customers network, then Sabre employees will purchase and be reimbursed for coach class travel on another airline. Out of pocket expenses associated with the project include, but are not limited to, ground
transportation expenses while on-site and during transit; lodging, food and incidental expenses incurred in the performance of this Agreement in accordance with the related Work Order.  

c) Payment Procedures Payment will be made by wire transfer to an account designated to Customer by Sabre. All fees and charges shall be
due and payable forty-five (45) days after receipt of invoice from Sabre. Each monthly invoice will itemize the fees and charges, and will be accompanied by reasonable detail. If an Affiliate of Sabre performs any of Services, Sabre may opt for
such Affiliate to invoice Customer for the Services it provides, in which case Customer will pay that Affiliate directly. Interest on any late payments shall accrue at the rate of one and one half percent (1.5%) per month or the highest rate
permitted by applicable law, whichever is less, from the date such amount is due until finally paid. 
 d) Payments without
Set-Off. All payments by the parties hereunder shall be paid to the other party without set-off or reduction for any amounts owed, or claimed, from the parties. Parties hereby waive and disclaim any rights of offset or set-off. 

e) Taxes. The fees and charges listed in this Agreement and Work Orders do not include taxes, duties or other assessments. Customer will be
responsible for and will reimburse Sabre for all taxes or similar charges that are related to this Agreement or to payments made under this Agreement, other than taxes imposed on the net income of Sabre (collectively, “Taxes”). If Customer
is required by law to make any deduction or withholding of Taxes from any payment due to Sabre under this Agreement, Customer will (i) timely and properly prepare and submit any necessary filings and remit such Taxes to the appropriate taxing
authority, (ii) provide Sabre with governmental receipts evidencing Customer’s withholding and payment to the appropriate tax authorities in a timely manner and (iii) increase each payment related to this Agreement to the extent
necessary to ensure that Sabre actually receives the amount that Sabre would have received if such payment had not been subject to Taxes.  
 Sabre hereby agrees to provide Customer any documentation reasonably requested by Customer to allow Customer to comply with its obligations under

 
the applicable tax law with respect to the transactions covered by this Agreement, including without limitation, (i) a tax residency certificate, currently Form 6166, issued by the U.S.
Department of the Treasury (Internal Revenue Service) or any substitute thereto, and (ii) upon request from Customer seek a provide Customer a new Form 6166 (or any substitute thereto), from the U.S. Department of Treasury. 

4. Intellectual Property 
 a)
Sabre Retention of Rights. Sabre retains exclusive ownership of all worldwide Intellectual Property Rights in the System(s) and Documentation, including any derivative work, modification, Update or Version thereof. Sabre and its suppliers
reserve all rights in and to the System and Documentation not expressly granted to Customer in this Agreement. 
 b) Express Restrictions.
The System(s), and its structure, organization, and source code constitute valuable trade secrets of Sabre. Unless otherwise permitted under the applicable Work Order, Customer agrees not to (i) modify, adapt, alter, translate, or create
derivative works from a System; (ii) merge a System with other software; (iii) sublicense, lease, rent, or loan a System to any third party; (iv) reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code
for a System; or (v) otherwise use or copy the System except as expressly allowed in this Agreement. Decompiling a System is permitted to the extent the laws of Customer’s jurisdiction give Customer the right to do so to obtain information
necessary to render a System interoperable with other software; provided, however, that Customer must first request such information from Sabre and Sabre may, in its discretion, either provide such information to Customer or impose reasonable
restrictions, including a reasonable fee, on such use of a System to ensure that Sabre’s and its suppliers’ proprietary rights in the System are protected. 
 c) Backup Copies. For Systems and Documentation delivered to Customer by Sabre, Customer may make a reasonable number of copies solely for the permitted use and for backup purposes. Customer shall
reproduce on each copy and on each partial copy of a System or Documentation any copyright notice and proprietary rights legend contained therein, as such notice and legend appear in the original. 

5. Indemnification. 
 a) Sabre
will defend, indemnify and hold harmless, at its expense, any action brought against Customer, Customer Affiliates, and their respective directors, officers and employees, to the extent that such action is based on a claim of Infringement. Sabre
will pay any and all damages and costs (including reasonable attorney fees) incurred by

 

  

			
	Sabre Inc. — Confidential	 	2

 
Customer that are attributable to the Infringement, provided that Sabre is promptly informed in writing and furnished a copy of each communication, notice or other action identifying any third
party patent or copyright or relating to the alleged Infringement and is given information and assistance necessary to defend or settle such claim. Customer’s failure to promptly notify Sabre of an Infringement claim shall not relieve Sabre of
any liability under this Section except to the extent that the defense of such action is prejudiced thereby. 
 b) Should any portion of a
System as delivered by Sabre hereunder become, or in Sabre’s opinion is likely to become the subject of a claim of Infringement, then Sabre may, at its option and expense: (i) procure for Customer the right to use the System free of any
liability for Infringement; or (ii) replace or modify the applicable portion of the System with a non-Infringing substitute otherwise complying substantially with the description of the System in the Work Order. If (i) or (ii) are not
commercially and/or economically feasible, Sabre may accept return of the System and reimburse Customer for the implementation and license fees (but not Access Fees) actually paid to Sabre by Customer depreciated on a three year straight line
depreciation schedule. 
 c) If any action is brought against Sabre based on a claim that (i) software code or documentation written by
Customer or any data or information added to a System by Customer or by any other person or entity at Customer’s request; (ii) use of a System in combination with, or in addition to, equipment or computer programs not licensed or developed
by Sabre; (iii) any modification or alteration of a System by Customer or its third party agents or contractors; or (iv) any breach of this Agreement by Customer, constitutes an Infringement, then the indemnity obligation stated in this
Section “Indemnification” with respect to Sabre shall reciprocally apply to Customer. If the parties cannot clearly determine whether the Infringement action is based on the actions of Sabre or of Customer, Sabre may exercise sole control
over the defense and Customer will cooperate with Sabre in such defense. No compromise or settlement of any claim or proceeding may be affected or committed to by Sabre without Customer’s prior written consent, which consent shall not be
unreasonably withheld or delayed. 
 d) The foregoing shall constitute Sabre’s sole and exclusive obligation, and Customer’s sole and
exclusive remedy, for any Infringement by a System of any Intellectual Property Rights. 
 e) Except as expressly provided for in this Section,
Customer shall defend, indemnify and hold harmless Sabre from any and all claims or causes of action arising out of Customer’s use of a System, including but not limited to Customer’s use of the System in combination with, or in addition
to, any

 
equipment or computer programs not licensed or recommended by Sabre. Customer shall pay any and all damages and expenses (including reasonable attorney fees incurred by Sabre) in connection with
such claims, regardless of the circumstances of the claim or damage. 
 6. Disclaimer of Warranty. 

SABRE DISCLAIMS ALL WARRANTIES, EXPRESS, IMPLIED, OR STATUTORY, REGARDING THE SYSTEM(S) AND SERVICES, INCLUDING ANY WARRANTIES OF, MERCHANTABILITY,
FITNESS FOR A PARTICULAR USE OR PURPOSE, TITLE, AND NONINFRINGEMENT. NO REPRESENTATION OR OTHER AFFIRMATION OF FACT SHALL BE DEEMED A WARRANTY FOR ANY PURPOSE OR GIVE RISE TO ANY LIABILITY OF SABRE WHATSOEVER. CUSTOMER ACKNOWLEDGES THAT IT HAS
RELIED ON NO WARRANTIES OTHER THAN THE EXPRESS WARRANTIES IN THIS AGREEMENT. 
 7. Non-Disclosure.

Information shall be held and protected by the recipient in strict confidence, and shall be used by the recipient only as required to render performance or to exercise rights and remedies under this Agreement. Each party will protect the other
party’s Confidential Information from unauthorized use, access or disclosure with the same measures that the recipient takes to protect its own proprietary information of like importance, but in no event less than reasonable care. No
Confidential Information will be disclosed to any third party by the recipient party without the prior written consent of the disclosing party, except that each party may disclose this Agreement and the other party’s Confidential Information to
its Affiliates and their respective directors, employees, attorneys, agents, auditors, insurers and subcontractors who require access to such information in connection with their employment or engagement and who are obligated to keep such
information confidential in a manner no less restrictive than set forth in this Section. The party employing or engaging such persons is responsible and liable for their compliance with such confidentiality obligations. 

b) Required Disclosures. Each party may disclose the Confidential Information of the other party in response to a request for disclosure by a
court or another governmental authority, including a subpoena, court order, or audit-related request by a taxing authority, if that party; (i) promptly notifies the other party of the terms and the circumstances of that request,
(ii) consults with the other party, and cooperates with the other party’s reasonable requests to resist or narrow that request, (iii) furnishes only information that, according to written advice of its

 

  

			
	Sabre Inc. — Confidential	 	3

 
legal counsel, that party is legally compelled to disclose, and (iv) uses reasonable efforts to obtain an order or other reliable assurance that confidential treatment will be accorded the
information disclosed. 
 8. LIMITATION OF LIABILITY. WITH THE EXCEPTION OF LIABILITY FOR DEATH OR PERSONAL INJURY CAUSED BY THE
NEGLIGENCE OF EITHER PARTY (FOR WHICH NO LIMIT SHALL APPLY), EACH PARTY WAIVES ALL LIABILITY OF THE OTHER PARTY, ITS LICENSORS AND SUPPLIERS FROM NEGLIGENCE, WHETHER CONTRIBUTORY, SOLE OR JOINT. EXCEPT FOR EITHER PARTY’S BREACH OF THE
NON-DISCLOSURE OBLIGATIONS OR CUSTOMER’S BREACH OF THE USE RESTRICTIONS PLACED ON THE SYSTEM(S) UNDER THIS AGREEMENT AND THE APPLICABLE WORK ORDERS, NEITHER CUSTOMER, SABRE OR SABRE’S LICENSORS OR SUPPLIERS SHALL BE LIABLE FOR ANY LOST
PROFITS, REVENUE OR SAVINGS OR FOR ANY INCIDENTAL, INDIRECT, EXEMPLARY, SPECIAL OR CONSEQUENTIAL DAMAGES, UNDER ANY CIRCUMSTANCES, EVEN IF SUCH PARTY HAD BEEN ADVISED OF, KNEW, OR SHOULD HAVE KNOWN, OF THE POSSIBILITY THEREOF. UNDER NO CIRCUMSTANCES
SHALL SABRE’S AGGREGATE CUMULATIVE LIABILITY HEREUNDER, WHETHER IN CONTRACT, TORT, OR OTHERWISE, *****. EXCEPT FOR THE PAYMENT OF AMOUNTS DUE AND PAYABLE HEREUNDER, UNDER NO CIRCUMSTANCES SHALL CUSTOMER AGGREGATE CUMULATIVE LIABILITY HEREUNDER,
WHETHER IN CONTRACT, TORT, OR OTHERWISE, ***** CUSTOMER ACKNOWLEDGES THAT THE FEES PAID BY IT REFLECT THE ALLOCATION OF RISK SET FORTH IN THIS AGREEMENT AND THAT SABRE WOULD NOT ENTER INTO THIS AGREEMENT WITHOUT THESE LIMITATIONS ON ITS LIABILITY.

 9. General Terms and Conditions.  
 a) As soon as reasonably possible following the Customer placing a System into Productive Use under any Work Order, Customer, individually or jointly with Sabre, will issue, with the prior written consent
of the Costumer a press release that makes reference in the lead that the applicable technology was enabled by Sabre Airline Solutions and specifically identify the applicable System(s) and/or Services within the body of the release. This press
release will be approved by both parties prior to issuance. Sabre may also identify Customer as one of its clients in general promotional literature and disclose to current and prospective clients that Sabre has provided Customer with the System(s)

 b) Choice of Law. This Agreement and any dispute arising hereunder shall be construed in accordance with the laws of the State of New York without regard to principles of conflict of laws. This
Agreement will not be governed by the U.N. Convention on Contracts for the International Sale of Goods, the application of which is expressly excluded. The parties hereby irrevocably submit to the jurisdiction of the United States District Court

 
located in the borough of Manhattan, New York and each party waives any objection which it may have to the laying of venue of any suit, action or proceeding arising out of or relating to this
Agreement in such Court. 
 Notwithstanding anything herein to the contrary, in the event of an actual or threatened breach of the use
restrictions placed on the System(s) and Documentation or the Confidentiality provisions contained herein, the non-breaching party will be entitled, without waiving any other rights and remedies and without obligation to post a bond, to such
injunctive or equitable relief as may be deemed proper by a court of competent jurisdiction. 
 c) Force Majeure. Either party shall be
excused from performing hereunder (except for the payment of money) to the extent that it is prevented from performing as a result of any act or event which occurs and is beyond its reasonable control, including, without limitation, acts of God,
war, action of a governmental entity, strikes, lockouts, insurrection, protest, security breaches or other hostilities, embargos, blockades, fuel or energy shortages, transportation delays or the inability to obtain necessary labor, materials or
utilities from usual sources; provided that the party experiencing the force majeure provides the other with prompt written notice thereof and uses all reasonable efforts to remove or avoid such causes. If the inability to perform or deliver
continues for longer than fifteen (15) days, either party may terminate this Agreement by providing written notice to the other party. 

d) Savings Clause. If any provision of this Agreement is prohibited by law or held to be unenforceable, the remaining provisions hereof shall not
be affected, and this Agreement shall continue in full force and effect as if such unenforceable provision had never constituted a part hereof, and the unenforceable provision shall be automatically amended to so as to best accomplish the objectives
of such unenforceable provision within the limits of applicable law. 
 e) Relationship. Sabre is an independent contractor hereunder and
no employee of either party shall be deemed to be an employee of the other for any purpose whatsoever. Nothing shall be construed to create a partnership, joint venture or agency relationship between the parties. Each party shall comply, at its own
expense, with the provisions of all applicable state and municipal requirements and with all state and federal laws applicable to it as an employer and otherwise. 
 f) Assignment. Neither party may transfer or assign this Agreement to any other person or entity, whether by operation of law or otherwise, without the prior written consent of the other party
except that (i) the parties may assign this Agreement to an Affiliate 

 

  

			
	Sabre Inc. — Confidential	 	4

 
provided that the assigning party remain primarily liable for the assignee’s on-going performance hereunder, and (ii) either party may assign this Agreement to an third party who
acquires all or substantially all of the assignors assets (whether by merger, change of control or otherwise) as long as the assignee expressly agrees to assume all rights and obligations hereunder of the assignor.. 

g) Notices. All notices required to be sent and service of process hereunder shall be in writing and deemed to have been given upon delivery
(i) by commercial courier with delivery tracking capabilities, or (ii) if by certified mail return receipt requested, or (iii) by hand delivery to the addresses set forth below the signature line below, or to such other address or
individual as the parties may specify from time to time by written notice to the other party. Each party agrees that any notice or service of process by any of the methods set forth above is adequate for all purposes and each party expressly waives
any requirement of any other form of notice or service of process. 
 h) Export. If required, Sabre will use commercially reasonable
efforts to obtain all approvals necessary to export the System to Customer’s location. In the event that such approvals are refused, either party may terminate this Agreement or a relevant Work Order, and neither party shall be liable to the
other for any resulting loss or expense. Customer will comply fully with all applicable United States and foreign government export and import control laws and regulations in its use of a System and, in particular, Customer will not export or
re-export any System without all required United States and foreign government licenses. Customer will defend, indemnify and hold harmless Sabre from and against any violation of such laws or regulations by Customer or any of its agents, officers,
directors or employees. Without limiting the generally of the foregoing, Customer shall not, and shall cause its representatives not to, export, directly or indirectly, re-export, divert, or transfer the System(s),

 
Documentation or any direct product thereof to any destination, company or person restricted or prohibited by the United States Export Control. 

j) Waiver. The waiver by either party of any default or breach of this Agreement shall not constitute a waiver of any other or subsequent default
or breach. Except for actions for nonpayment or breach of Sabre’s Intellectual Property Rights in the System(s) or Documentation, no action, regardless of form, arising out of this Agreement may be brought by either party more than one year
after the cause of action has accrued. 
 k) Miscellaneous. All obligations hereunder are subject to the receipt of all necessary
government approvals. This Agreement, together with each Work Order referencing this Agreement, constitutes the entire agreement between the parties related to the subject matter thereof, supersedes any prior or contemporaneous agreement between the
parties relating to the performance of work under a Work Order, and shall not be changed except by written agreement signed by an officer of each party. If any terms in the Work Order conflict with the terms of this Agreement, the terms of the Work
Order shall supersede the terms of this Agreement for that engagement. This Agreement may be executed in counterparts, each of which shall be deemed an original but all of which together will constitute the same instrument. The exchange of a fully
executed Agreement (in counterparts or otherwise) by fax shall be sufficient to bind the parties to the terms and conditions of this Agreement. 

l) Survival. All terms of this Agreement, which by their nature are intended to survive termination of this Agreement, including without
limitation, sections entitled “Effects of Termination”, “Fees and Payment”, “Intellectual Property”, “Indemnification”, “Disclaimer of Warranty:, “Non-Disclosure”, “Limitation of
Liability”, “Choice of Law”, “Claims Period”, “Savings Clause”, “Notices”, “Export:, “Miscellaneous”, and “Survival”, shall survive termination.

	 	(r)	The ROE Display – FC function displays IATA quarterly NUC conversion rates of exchange. 

  

					
	Confidential	  	Page 18	  	

	 	(s)	The Currency Management (Conversion Functions) function displays the Bankers Selling Rate (BSR) for the country requested. This function converts currency at the
market rate. Currency Management also contains an alpha listing of all country currencies, as well as, a conversion for the BSR. 

  

	 	(t)	The Tax Display – TX function displays country or city specific taxes. 

 

	 	(u)	The MPM Mileage Display – WN function displays applicable maximum permitted mileage for MPM fare levels. 

 

	 	(v)	The Ticketed Point Mileage Display – WN function calculates miles traveled between ticketed points for fare and routing applicability.

  

	 	(w)	The PFC Display – PXC function calculates applicable passenger facility charge for domestic and international itineraries. 

 

	1.3	Codeshare 

 Unlimited
codeshare flights are included in this Work Order for up to three (3) codeshare partner airlines to be implemented at cutover. Additional Codeshare partners implemented after cutover are not included. Codeshare flights refer to flight numbers,
either marketing or operating. An agreement with the other carrier is required. 
  

	 	(a)	The Codeshare function provides the ability for an airline to partner with another airline to offer services to cities where the host airline does not fly.
Additional market availability is provided without the added cost of aircraft, flight crew and airport facilities. The SabreSonic system currently supports IATA Options 1, 2, 3, and 4. The SabreSonic codeshare product is very flexible; allowing the
carrier many choices in how various bookings and responses will be sent and processed. When a passenger checks in on the SabreSonic—hosted carrier’s flight that connects with a marketing flight, SabreSonic recognizes the codeshare flight;
if the operating carrier has an EDIFACT agreement with the operating carrier, then EDIFACT Through Check-In is performed. This product requires a Codeshare agreement. 

 

	 	(b)	The Codeshare Marketing TCS Date Relate functionality allows carriers participating in codeshare arrangements to link classes of service to dates in the TCS
(Teletype Codeshare Table) enabling them to add effective and discontinue dates ensuring the marketing carriers classes of service are mapped and translated to the operating carrier’s classes of service for the exchange of booking data.

  

	 	(c)	The Operating TCS Table gives the operating carrier more control over what classes of service are being booked by the marketing carrier. This table is used to
validate the fare class mapping translations for inbound IATA Option 1 and 4 booking messages sent by the marketing carrier. It is also used to translate the marketing carrier class to the operating carrier class of service for IATA Option 2
bookings and AVS messages. 

  

	 	(d)	The PNL Check-In Enhancement function searches for existing PNR’s within SabreSonic when an inbound PNL/ADL message is received and merges the data found in
the PNL with the existing Sabre PNR. This eliminates dupe bookings. It also enables the system to perform “ through check-in” on their passengers from their origin city to their final destination. 

 

	 	(e)	The AVS Leg and Segment Support function applies the Availability Status (AVS) messages to both the operating and marketing carriers when an AVS message is sent.

  

	 	(f)	The Request Availability Status Message (RAS) function allows additional control of a carrier’s marketing flights. This product enables the marketing
carrier to send an Availability Status (AVS) recap request to the operating carrier at any given time. Upon receipt of the message, the operating carrier will automatically return an AVS message (recap) to the marketing carrier. SabreSonic has the
capability to send and receive RAS messages. 

  

	 	(g)	The Passenger Name Record (PNR) Identification by Record Locator (RLOC) function attempts to retrieve a PNR in two ways in order to process inbound Teletype
messages. The first check searches the OA RLOC (Other Airline Record Locator) Index for the originating airline’s RLOC; if the PNR is not found, the system will attempt to retrieve the PNR via flight, name, date. 

  

					
	Confidential	  	Page 19	  	

	 	(h)	The Open Seat Indicator on Boarding Passes function enables EDIFACT to print ‘OPN’ in the seat assignment field on ATB2 boarding passes issued via
EDIFACT for OA open seating flights. This functionality is available for all EDIFACT partners who send an open seating indicator in the check-in response (DCRCKA). 

 

	 	(i)	The LDX function will produce the Codeshare PNR Reconciliation Report from the Marketing Carrier’s Partition. The report will include an item for each PNR
that was booked by the Marketing Carrier and is missing from either the Marketing or Operating Flight. 

  

	 	(j)	The Flight Segment Included in Teletype Reply to SSR Request function provides for the flight segment associated to an SSR to be included in the SSR reply
message. 

  

	 	(k)	The Inbound Passenger Reconciliation List (PRL) Enhancement provides information collected during the check-in process that can be used to update a ground
handled/marketed airlines’ reservation system, as necessary. The PRL message reflects a list of accommodated onboard passengers and associated information. 

 

	 	(l)	The “SOLD AS” Identifier on Boarding Passes function modifies the current boarding pass stub to include a “SOLD AS” field to reflect the
Marketing carrier’s code and flight number when operated by a codeshare partner. This provides the passenger with information associating the codeshare partner’s base operating flight number to the flight originally booked.

  

	 	(m)	The IATA Passenger Final Sales - Outbound Message is a teletype message generated during the post departure reconciliation process to provide post departure
control statistical and/or amended passenger information to codeshare/contracted 3rd parties. The Post Final Sales message lists all “exception” passengers, or passengers who did not check in “normally”. The passengers are listed
first by category, then class of service, and lastly alphabetically. A passenger will appear in only one category. 

  

	 	(n)	The Codeshare Prepaid Ticket Advice provides the ability for the passenger to pickup a prepaid ticket from either the marketing or operating carrier’s
ticket office. Upon issuance of the ticket a teletype message is automatically sent advising that the PTA has been ticketed. 

  

	 	(o)	The SabreSonic system has the ability to send, receive, and process Codeshare IATA Option 1 messages. With IATA Option 1, the marketing carrier performs the
translation to the operating carrier information. The marketing flight information is included at the end of the air segment. Therefore, the marketing carrier sends both marketing and operating carrier details within the booking message.

  

	 	(p)	The SabreSonic system has the ability to send, receive, and process Codeshare IATA Option 2 messages. With IATA Option 2, the operating carrier performs the
translation to the operating carrier information. The marketing carrier sends marketing flight information only. 

  

	 	(q)	The SabreSonic system has the ability to send, receive, and process Codeshare IATA Option 3 messages. With IATA Option 3, the marketing carrier performs the
translation to the operating carrier information. The marketing carrier sends operating flight information only. 

  

	 	(r)	The SabreSonic system has the ability to send, receive, and process Codeshare IATA Option 4 messages. Codeshare IATA Option 4 is similar to Option 1, however the
booking format is slightly different. The marketing carrier performs the translation to the operating carrier information and both flights are included in the air segment. 

 

	 	(s)	The Codeshare Automated Passenger Protection (APP) function allows the operating and marketing carrier to determine who will be responsible for reaccommodating
the marketing codeshare passengers during schedule change. If it is determined that the operating carrier will be responsible for reaccommodating the marketing passengers, teletype messages are created to update the marketing PNRs and processed
according to the rules of each partner. Additionally, the SabreSonic operating carrier may protect marketing carrier’s passengers separately from their own non-codeshare passengers. Each codeshare may be protected differently as well.

  

					
	Confidential	  	Page 20	  	

	 	(t)	The Codeshare Availability Status Messages (AVS) Reapply function re-applies AVS inhibits, previously applied by the operating carrier from an AVS open or close
message, after the marketing carrier’s schedule change. 

  

	 	(u)	True Availability allows a marketing flight’s Inventory Detail record (IND) to be programmatically linked to the IND of the operating carrier, when both
airlines reside in the SabreSonic system. Therefore, the availability of the marketing flight will mirror the availability of the operating flight, reflecting its “true availability”. A ‘TAI’ indicator in the city pair
availability demonstrates to the marketing carrier that the city pair is displayed as ‘true availability’. Additionally, True Availability supports all Sabre inventory structures (Net, Threshold, Virtual and Continuous Nesting).

  

	 	(v)	The FLIFO Cancellation function appends a FLIFO cancellation message on the marketing flight when the operating flight is cancelled with a CN or CS action code.

  

	 	(w)	The Codeshare Seat Return-Outbound function provides the ability to return seats to the operating carrier by cabin, date range, time and origin or destination
for codeshare block space agreements. Codeshare Seat Return also creates the ability to retain a minimum number of block seats, to set new seat authorizations with adjustable overbooking levels, to provide return seat percentages and to establish
additional addresses for seat release messages. 

  

	 	(x)	The Dual Flight Number Validation function provides the ability to validate the dual flight number information is correct when it is received from the marketing
carrier. This function is applicable to IATA Option 4 codeshare partnerships only. 

  

	 	(y)	Codeshare Ticket Number Advice (TKNA) notifies the marketing carrier when the operating carrier tickets the PNR using paper ticketing. Upon completion of
ticketing the operating codeshare PNR, teletype will send an SSR TKNA to the marketing carrier, which will input a T- 20JUN (date ticket was issued by operating carrier), followed by the ticketing information in the marketing carrier’s
ticketing field. This will eliminate the possibility of the PNR being cancelled due to a ticketing time limit imposed by the marketing carrier at the time of booking. 

 

	 	(z)	Codeshare Flight Default permits the check-in agent to use the marketing carrier code and flight number when defaulting to a flight for check-in.

  

	 	(aa)	The Codeshare Agreement Table is a centralized location of all codeshare tables. This table will give the customer and the Sabre Codeshare representative the
ability to view all features that have been activated for any particular codeshare partnership without having to search different codeshare tables. 

  

	 	(bb)	Codeshare Numeric Availability Status Messages (AVA) provides the ability for a SabreSonic user to send and receive AVA messages for Availability Status
Messaging. AVA is an additional free flow availability message that provides more accurate inventory synchronization between codeshare partners. The availability message is in numeric format that includes all mapped classes of service (RBDs), both
public and non-public, for each compartment (F/C/Y). This differs from the standard AVS message, which includes only the classes affected by the change. By including the current availability for all RBDs, there is an inherent control feature that
allows the marketing carrier to maintain an accurate availability at all times. This functionality also includes the sending and receiving of AVA Recap Request messages (RVR) and AVA Recap Responses (AVR). 

 

	 	(cc)	Guaranteed Sell for Codeshare Flights enables the system to verify availability on the operating carrier’s codeshare flight prior to confirming an inbound
booking message from the marketing carrier. This will eliminate the number of codeshare overbookings on the operating carrier’s flight. 

  

	 	(dd)	The Automate Codeshare Schedule Change feature will automatically update the SabreSonic hosted marketing carrier’s flights and passengers when an operating
carrier’s schedule changes. For Sabre to OA codeshares, this feature will automatically generate a Standard Schedules Message (SSM) to the OA marketing carrier in order to update the marketing flight when the operating flight is created or
changed, reducing the number of flights with possible schedules out-of-synch. 

  

	 	(ee)	Ticket and Time Limit Notification notifies the booking source when the operating carrier tickets or adds a ticket time-limit to the Passenger Name Record (PNR).
This applies to interline and codeshare PNRs. Notification is generated in the form of an SSR TKNE, TKNA, or TKTL.

	1.4	Command CenterTM Interface 

Command CenterTM Interface is a web based graphical user interface (GUI) giving SabreSonic customers a tool to easily perform the
system configuration, table maintenance, and information reporting tasks for functions including: Market Tariff Table; Codeshare configuration and management; Pre-Reserved Seat Map configuration; Agreements management (Ticketing & Baggage
Agreements, Credit Card Acceptance agreements, and Frequent Flyer Agreements 
  

	1.5	Credit Suite 

  

	 	(a)	Basic Authorization 

 The
Credit Authorization (CAS) function provides the carrier the ability to obtain real-time, instantaneous credit authorization for major credit cards accepted as form of payment. Credit card numbers are first validated for accuracy upon input
into the system. After that, direct links between SabreSonic and the major credit card associations provide the carrier the means of obtaining a real-time approval code prior to issuance of a ticket. Alternatively, the automated approval code may be
substituted by the use of an on-line entry to approve credit prior to document issuance. 
  

	 	(b)	Credit Suite 

 The Data
Delivery function (also known as Accelerated Credit Card Billing or ACCB) allows carriers to accelerate settlement of American Express, Discover, MasterCard, Visa, JCB and Diners Club/Carte Blanche credit card transactions. Credit card
settlement data is captured and formatted according to preferences of airline’s credit card merchant bank(s)/processor(s). This information is transmitted “on behalf” of the carrier directly to the bank(s)/processor(s). The data is
sent daily, seven days a week, being electronically downloaded into the banks’ accounting systems, and therefore accelerating the process of recovery of credit card revenue by 5-8 days on average, considerably improving airline’s cash
flows. Credit card purchases for transportation tickets, as well as refund, exchange and miscellaneous transactions completed through the use of masks can be accelerated. Requires Sabre generated Ticket Number. Sabre supports encrypted FTP/IP
connectivity via Internet for the transmission of Credit Suite files. However, in specific cases, a dedicated communications link to the credit processor/bank may need to be installed. 

Interchange Optimization (also known as Payment Services 2000 or PS2000) represents Sabre’s flexibility to meet local
requirements from the card associations, in order to qualify the carrier for the lowest possible discount fees on transactions processed via the Data Delivery product. As an example, in the US, Visa and MasterCard’s “Passenger
Transport” qualification requirements are met by the inclusion of additional data fields in the settlement files sent to banks. Specific requirements need to be analyzed on a country by country basis. Magnetic card swipe reader devices may be
required. Interchange Optimization programs may require a contractual agreement between the carrier and the card associations. 
  

	 	(c)	Credit Suite - Fraud Prevention 

Address Verification Service (AVS) is an enhanced fraud tool that verifies that the address in the credit card data field matches
the address on file with the card issuer, allowing for more secure transactions. Currently available in the U.S., Puerto Rico and the U.S. Virgin Islands. 
  

	1.6	Customer Relationship Management Suite 

  

	 	(a)	CDD 

Customer Data Delivery – PNR and VCR Data (“CDD – PNR and CDD – VCR Data
Feed”) enables Sabre hosted airlines to receive structured data files containing normalized host airline Passenger Name Record (PNR) and Virtual Coupon Record (VCR) data. Information on all active PNRs and electronic tickets (VCRs) from
airline direct, agency, and other interline booking channels that are active in the host airline database in the
Sabre® Passenger Reservation System after date/time of implementation is included. The data is extracted
from the hosted airline database and is transmitted via scheduled batch feeds. 
 Data will be delivered to Customer via FTP on a
daily basis, in flat files, delimited data string format. 

  

					
	Confidential	  	Page 22	  	

	 	(b)	Customer Insight 

 Customer
Insight is a profile system that can be used as a central repository for customer profiles. The database is located on an open platform and supports flexible data access and update methods: Batch file updates via FTP, manual updates via the Sabre
system or the SabreSonic Agent Interface, and a web service interface based on OTA (Open Travel Alliance) standards. The data model utilized provides the ability for hosted airlines to store a wide variety of information regarding their customers,
for example: personal information, such as name, contact information and travel document information; air travel information such as customer value score, service needs such as airline seating, meals and class of service, also travel preferences,
frequent traveler information and employment information. Frequent Traveler profiles can be used during the booking process to quickly build a Passenger Name Record (PNR) by automatically moving profile information into the PNR with reduced
keystrokes and increased accuracy. The reservations and check-in functions integrate with Customer Insight in order to recognize an airline’s most loyal frequent flyer members. 

 

	 	(c)	Customer Value Calculator 

 The
Customer Value Calculator is a model which calculates a customer value score for each customer with a profile given a set of airline specified parameters. The application currently consists of three main areas: 

 

	 	•	 	 Parameter Inputs 

  

	 	•	 	 Graphical Distribution 

  

	 	•	 	 Parameter Set Management 

 The information below contains a description of these specific areas. 
 Parameter
Inputs: The model allows the user to configure three different parameters: Recency, Frequency, and Monetary Value. Recency represents the number of segments flown by a customer in a user specified period of time. This time period is generally short
in duration and is used to capture recent travel activity. Similarly, Frequency also represents the number of segments flown by a customer in a user specified period of time. However, the time period for this is generally longer than the Recency
time period. For example, whereas the time period of consideration for Recency might be 12 months, the Frequency time period may be 36 months. The final parameter in the model is monetary value. This parameter captures the amount of spend by a
customer in a user specified period of time. 
 The user has the ability to control each of these parameters in three ways: time
periods, ranges, and weights. Time periods, as discussed previously, define the time period for which the parameter will be calculated. Ranges give the airline the ability to tier the values for a particular parameter. For example an airline may
choose to assign values for recency like: 
  

	 	•	 	 Less than or equal to 2 would indicate a recency score of 0 

 

	 	•	 	 Between 3 and 6 (inclusive) segments would indicate a recency score of 30 

 

	 	•	 	 Between 7 and 10 (inclusive) segments would indicate a recency score of 70 

 

	 	•	 	 11 or more segments flown in the time period would indicate a recency score of 100 

Finally, the airline can set the relative weights of the parameters. For example, recency may compose of 20% of the customer value score,
frequency may compose of 30% of the customer value score, and monetary value may compose of 50% of the value score. 
 Once all
of these parameters are set then a customer value score can be calculated for each customer with a customer profile. The user can then save this parameter set under a unique name for further reference. 

Parameter Set Management: The third and final area of the Customer Value Calculator is the area of parameter set management. Airlines can
have multiple parameter sets with different goals and experiments using the what-if functionality of the model. 
 The Parameter
Set Management area allows users of the system to perform general management functions. This includes viewing, sorting, deleting, and renaming parameter sets. From the parameter set management area, a user can also tell which parameter set is
currently loaded in production as well as the next one queued for production if a change has been designated.

	Confidential	  	Page 27	  	

	 	(m)	The Extra Sections function allows for the addition of extra flights to the system outside of the schedule change process. Extra sections are used when the market
requires an additional flight for a limited operation - i.e.: 1 day or 1 day a week for the next month. 

  

	 	(n)	The Charters function enables two ways for charters to be input into the system. Charters input through a schedule change entry appear as any other flight. Charters
input with an inventory type entry using a specific flight number range are not shown in city pair availability. Seat maps and seat assignments, boarding passes, positive name match, on-board counts, no-shows and IATA Passenger Name Lists (PNLs) and
Add and Delete Lists (ADLs) are provided for charter flights. 

  

	 	(o)	The Schedule Change Reaccommodation function is an automated passenger reaccommodation process for passengers affected by schedule change. SabreSonic automatically
builds a candidate list for protection where the highest-ranking candidate (flight) is determined and used for the reaccommodation process. The ranking is determined by parameters defined by the carrier. Each carrier can also assign criteria values
to passenger PNR’s to determine the reaccommodation order by PNR attributes, such as frequent flyer, class of service, etc. The carriers also have the ability to define limits for flight overbookings during reaccommodation. There are two
reaccommodation options an airline can chose to implement: 

  

	 	(i)	O&D – Identifies protection for the whole journey, from origin to destination. 

 

	 	(ii)	Leg Based – Identifies protection for the affected legs. 

  

	 	(p)	The Commuter function provides the ability to designate up to 15 additional airlines as commuters, under the host airline code, by assigning a specific flight number
range and using an asterisk in the city pair availability display. Additionally, a message can be appended to flights in order to identify the name of the commuter airline in the city pair availability display. The Encode/Decode table contains the
commuter carrier name. 

  

	 	(q)	The Automated Overlap Flights function provides an automatic method for inventory control of the shared legs. Specifically, the Automated Funnel Flights function
provides an automatic method of updating seats sold for a change of aircraft which results in a connecting flight appearing as a direct flight in city pair availability. The Automated Overlap Flights function allows for the utilization of one
aircraft to operate as two flight numbers over a common city pair and automatically decrements inventory when a seat is sold. Overlap flights may or may not be a change of aircraft, which may result in passenger deplaning and enplaning. Only one of
the flight numbers will appear in the city pair availability for the common leg. 

  

	 	(r)	The Inventory Authorization - Flight Load Predictor (FLP) function is a nightly process used to adjust authorizations of flights. The authorizations specify the number
of seats available for sale in each class for a specific period before flight departure date. Manual entries exist to change or override these authorizations. FLP allows the ability to retain authorization levels through a schedule change.

  

	 	(s)	SSM provides the automated message transmission of SabreSonic schedule changes to be generated to another CRS. ASM provides the automated message transmission of adhoc
changes to be generated to another CRS, such as flight cancellation, entries changing arrival or departure times, and equipment changes. Available only with Amadeus, Galileo and Worldspan

completed and be available for revenue accounting purposes in an off-line file. 

  

	2.2	Electronic Ticketing 

  

	 	(a)	The Airline Direct Electronic Ticketing product provides computerized storage of the passenger’s entitlement to travel. The host airline maintains the accountable
travel and payment information in a real-time environment. Itineraries with up to 4 segments can be issued electronically. Electronic tickets are retained in the system until seven days after the last flight segment becomes inactive. An inactive
status could be flown, refunded or exchanged. If there is at least one active flight segment, the electronic ticket is retained for up to 396 days from the date of the first flight coupon. After all flight coupons have been used, the electronic
ticket is retained in the system for 7 days. 

  

	 	(b)	The Electronic Ticket Flown Virtual Coupon Record (VCR) contains data from the flown flights of tickets issued by the electronic ticketing product. The VCR is marked as

	 	(a)	The Change Fee Collection feature of the Automated Exchange product gives an airline the ability to ensure change fees are collected, or to waive and document the
reason for the waiver. For itineraries changed with the SabreSonic Res System prior to a passenger’s airport check-in, boarding pass issuance is inhibited at time of check-in until the agent either collects the fee or documents the reason for
waiver. The requirement of an explanation as well as the legend of waiver codes/ reasons is controlled by the airline via a user updateable table. In order for an airline to inhibit boarding pass issuance when an outstanding fee exists, an airline
must use SabreSonic Check-In in conjunction with the Change Fee Collection feature. The use of the Change Fee Collection feature includes the following reports: 

 

	 	(b)	Change Fees Collected file – Agent location, date, sine, and amount collected

corporations. The Airline Administration module provides access to customer data and program rules by customer service agents and marketing analysts. 
  

	8.1	Customer Access Module 

The Customer Access module is offered as a multi-language web site that is branded with the look and feel of your airline’s web site.
With secure account access and a user-friendly interface, the Customer Access module provides the following features: 
  

	 	(a)	Enrollment. Corporate enrolment can be direct or by invitation. A corporation is defined as either a business or travel agency. The enrolment pages can be offered to
the end user in their preferred language and communicates the terms and conditions of the program. 

  

					
	Confidential	  	Page 38	  	

	 	(b)	Profiles. The profile contains the corporation’s, associated travel agencies and account administrator’s details. Data collected about the company can be
mandatory or optional. Information can be changed by the user at any time once they have logged in. 

  

	 	(c)	Account Statements. These monthly statements provide details of transactions, both accrual and redemption, in an easy-to-read layout. Clickable links provide detailed
transactional information. 

  

	 	(d)	Program Feedback. ¬Users can provide feedback and ask questions about the program via two links. Contact Us and the Feedback Form let users interact with the
airline, if desired, in an easy-to-use online format, helping to reduce calls to the airline customer care center. 

  

	 	(e)	Customer Touch Points. A number of options are available that let you communicate with your customers either through rules that trigger an e-mail or via the e-mail tool
that enables you to send emails to a group of users or all users keeping them informed of new program features or other marketing information. 

  

	8.2	Airline Administration Module 

 The Airline Administration module consists of six sub-modules. 
  

	 	(a)	Translation. The translation tool enables airlines to dynamically change the text on the Web site to the chosen language. You can input text in the languages presented
to your users differing per market or use the entered default text in all markets. The translation tool supports double-byte characters and non-Western languages. 

 

	 	(b)	Multi Level Security Access. This sub-module enables airlines to control access to the administration module on a per tool basis. The tool let you provide overall
access or access to just one tool within the administration GUI. This allows the airline to grant access to various site functionality based on the needs of different groups within the airline, such as reporting or the ability to update text on the
Web site without allowing access to all of the tools. 

  

	 	(c)	Promotions. This set of tools provides the ability to set up promotions such as a bonus for users when they join the program based on travel information such as class
of travel, date of travel or origin and destination. Promotion rules can be set within each tool, and each promotion can be offered in all or specific markets. 

 

	 	(d)	Revenue Growth. This sub-module provides the airline with the ability to set revenue growth targets either by market or corporation. Additional accrual can apply if
target levels are reached.

account and view profile information and a list of sold tickets associated with the selected account. Agency account configurations such as commission and tax on commission levels, whether credit is extended or not and the credit limit, credit card
payment only details and the GSA (general sales agent) associated to an agency. 

  

	 	(f)	Credit Limits – the airline allocates a credit limit to the agency and once the credit limit is reached no further sales can be made where the agency is using a
distribution channel that has real time integration. The airline is alerted when an agency reaches their credit limit. The agency is alerted when they are within a % of using their available credit. An airline would typically set the credit limit in
line with a financial guarantee that they have in place with the agency. On an agreed timetable the statement will generate to the account in the form of an invoice for payment to the airline. 

 

	 	(g)	Pre paid accounts – if the currency is monetary, funds can be deposited in a travel agency account when the agency makes a payment to the airline. Sales are then
decremented against that prepayment. Both the agency and the airline are advised when the agency is with a % of using all available funds. This allows an airline the ability to receive an upfront payment and deposit those funds for future purchases.

  

	 	(h)	Credit card – transactions completed by credit card (airline must be the merchant on the card) must be settled through the airlines credit card vendor. However the
system allows tracking of the sale and calculates the commission owed to the agency by the airline.

	12.	REVENUE INTEGRITY MANAGER 

System(s) provided under the Work Order include the following: 
 The Revenue Integrity product is a hosted solution provided by Sabre to help airlines with flight firming and ensure that seat availability is not wasted. Airlines routinely lose valuable dollars through
unnecessary spoilage of seats, caused by expired ticket time limits, duplicate segments in a PNR, etc. as it is a very cumbersome and time consuming task to search for such PNRs. 

The Revenue Integrity product provides an automated way to search for undesirable PNRs using data available in our off-host PNR storage
warehouse. The advantage of searching on Sabre’s off-host PNR storage warehouse is that host partition access is minimized, thus saving on expensive message count hits. 
 A user may configure which PNRs are processed and actioned using configurable business rules. The system also provides the capability for the user to status their own particular processes at any time.
Status will show the time that the process initiated and completed, as well as the number of PNR’s processed up to that point. The system also provides the capability for users to view their own results data in a report form online via HTML web
pages and/or be exporting to MS EXCEL. 
 Note: Revenue Integrity provides nine (9) of the pre-defined processes (as
documented below), which the airline can choose to configure and run via the Command GUI. 

  

					
	Confidential	  	Page 44	  	

 The following is a description of all nine of the current Revenue Integrity pre-defined
processes to choose from: 
  

	 	(a)	Ticket Time Limit Processing. The “Ticketing Time Limit” process aims to minimize the effects of agents who book seats without ticketing the bookings.
Agents do this to ‘keep hold’ of a seat. There are a variety of reasons why they might do this. They might do this in good faith because a passenger needs a little bit more time to confirm and pay for the booking. Alternatively, they might
do this in bad faith to block off seats on a flight with the expectation that they will be able to sell these seats closer to the date of departure. 

  

	 	(b)	Duplicate Segment Processing (in the same PNR). The “Duplicate Segment” process aims to minimize the effects of agents who book multiple segments with
the same origin and destination and the same departure date (or a date within 1 day of each other) in the same PNR. Agents might do this to allow a customer to hedge their bets. 

 

	 	(c)	Duplicate PNR Processing (across multiple PNRs). The “Duplicate PNR” process aims to minimize the effects of agents who book multiple segments with the
same origin and destination and the same departure date (or a date within 1 day of each other) for the same passenger in different PNRs. 

  

	 	(d)	Passive Segment Processing. The “Passive Segment” process aims to reduce GDS costs associated with abusive use of passive segments. It should be noted
that a segment that is booked as a passive segment results in GDS costs for the airline unless cancelled promptly. Note Pre-requisite: Airlines must have the Passive Segment Notification feature activated in the SabreSonic host system in order to
use this Revenue Integrity process. 

  

	 	(e)	Fictitious Booking Processing. The “Fictitious Booking Process” aims to minimize the effects of agents who make bookings with closely similar names,
fictitious names (Mouse/Mickey, Test, etc). There are normally two sources of fictitious bookings, abusive agents or developers working in the airline industry who are testing their software. Abusive agents create fictitious bookings in order to
block off seats on a flight with the expectation that they will be able to sell these seats closer to the date of departure, or to earn GDS credits. Developers often forget to remove fictitious bookings after their testing is complete and are also a
source of unnecessarily blocked seated availability. Note: This process requires the Airline to provide a list of any known fictitious names (i.e. names possibly used for testing purposes and / or those names known as frequently used by travel
agencies to hold space) and upload that list into the Revenue Integrity system. Once the airline’s list is uploaded, the Revenue Integrity application will run its search and matching criteria against that data to determine possible fictitious
/ duplicate names used within PNRs. 

  

	 	(f)	Fictitious Ticket Number Processing. The “Fictitious Ticket Number Process” aims to minimize the effects of agents who create bookings and then pretend
to ticket them in order to avoid cancellation of the booking after the ticketing time limit. Agents do this to ‘keep hold’ of a seat so that they will be able to sell these seats closer to the date of departure. The “Fictitious Ticket
Number” check does a search on a ticket number match against a list that the airline has created (.csv or .txt) and uploaded into the revenue integrity tool. Note: This process requires the Airline to provide a list of their known fictitious
ticket numbers and upload that list into the Revenue Integrity system. Once the airline’s list is uploaded, the Revenue Integrity application will run its search and matching criteria against that data to determine possible fictitious ticket
numbers found in all PNRs. 

  

	 	(g)	Special Passenger Processing. The “Special Passenger Process” is used to check for PNRs that contain passengers that the airline wishes to flag at the
time of booking. This can include VIP or restricted passengers. The “Special Passenger” check does a search on a name match against the special passenger list(s) that the airline has created (.csv or .txt) and uploaded into the revenue
integrity tool. Note: This process requires the Airline to provide a list of their known “special passenger names” and upload that list into the Revenue Integrity system. Once the airline’s list is uploaded, the Revenue Integrity
application will run its search and matching criteria against that data to identify a list of PNRs that match known “special passengers” so the airline can then action as needed. 

 

	 	(h)	 Restricted Credit Card Processing. The “Restricted Credit Card Process” is used to check for PNRs that contain bookings made with a
credit card that the airline has restricted. The “Restricted Credit Card” check does a search on credit card numbers against a restricted credit card list that the airline has created (.csv or .txt) and uploaded into the revenue integrity
tool. Note: This process requires the Airline to provide a list of their known restricted credit card numbers and upload that list into the 

  

					
	Confidential	  	Page 45	  	

	 	
Revenue Integrity system. Once the airline’s list is uploaded, the Revenue Integrity application will run its search and matching criteria against that data to determine possible matches of
PNRs that contain identified restricted credit card numbers 

  

	 	(i)	Auto Teletype Reject Message Queue Processing. The “Auto Teletype Reject Queue Process” offers a configurable robotic application to automatically work
a vast majority of an airline’s teletype reject messages on a queue. This process allows a set of User-configured rules to be applied to each teletype reject message type. Each TTY message is read as it falls on the carrier-specified queue and
is then actioned according to the rules defined by the User. Although 100% of all teletype reject message scenarios cannot be automatically processed, airlines can now automate the processing of a significantly higher percentage of the most common
reject scenarios and reduce the amount of resources previously allocated to manually work TTY reject queues. 

  

	12.2	Newly Developed Revenue Integrity 

 The Revenue Integrity System will include the newly developed Revenue Integrity processes and enhanced process capability upon Customer’s cutover including: 

 

	 	(a)	Enhancement to the Fictitious Ticketing process. Sabre agrees to enhance the existing Fictitious Ticket Process to contain an “embedded list of known lost
and stolen ticket numbers (from ARINC subscription list) and also do automatic comparison with all ticket numbers previously shown as issued in Customer Sabre partition PNRs. Note: Customer must subscribe to ARINC Lost and Stolen Ticket Number data
solution. 

  

	 	(b)	New Watchlist Fraud Detection Process. The new Revenue Integrity Watchlist Fraud Protection process will be created to augment the Sabre host Watchlist process
that matches on name only. The new Revenue Integrity Watchlist Fraud Protection process will work 24 X 7 in addition to the host Watchlist process and will enable the airline to enter additional elements into a Table that will be used to better
identify potential scenarios of traveler fraud. A User will enter elements specific to a known traveler name into a Revenue Integrity Table that automatically sends that Table content to Sabre Traveler Data Warehouse to use in search and comparison
to return PNRs that match on specific elements. Customer can have the process automatically queue place PNRs to one or multiple queues so that different actions can be taken based on which element(s) is /was matched. Elements used for matching that
Customer can input into the Table will include: 

  

	 	(i)	Passport number 

  

	 	(ii)	Address 

  

	 	(iii)	Date of birth 

  

	 	(iv)	Email address 

  

	 	(v)	Phone number 

  

	 	(vi)	Origin and Destination 

  

	 	(vii)	Credit card number 

  

	 	(viii)	Name 

  

	 	(ix)	IP address if known from past or present booking 

  

	 	(c)	New Credit Card Fraud Check Process. This new process will work behind the scenes (To be determined if this can be done before ticketing on every ticket or right
after issuance on some tickets) – this process will need to read the BIN number on the credit card (first 6 digits of the credit card tells type of credit card and the specific bank that issued the card) and the process will call a table or use
a web service to send a message to the specific bank to validate if the card owner did in fact purchase a ticket with this credit card number. Credit Card company will contact card holder and if the bank verifies that the card holder did not
purchase the ticket, the process will receive a response (possibly via web service – To be determined) and the process will email a specific airport contact based on the email address Customer provides for all Airport locations to prevent
passenger boarding. 

  

					
	Confidential	  	Page 46	  	

	 	(i)	An additional part of this process needs to support other responses from the Credit Card Company such as notification that the card number in question is approved,
declined, reported as stolen / hot, or to pick up the credit card and prevent use. 

  

	 	(ii)	Also as part of the new credit card fraud protection capability, this process will include the ability for Customer to set a “credit card charge limit or
threshold”. This will enable the system to alert Customer staff when multiple charges on the same day or over a set period of time occur on the same credit card number and exceed a pre-specified dollar amount. Example is to find same credit
card charged multiple times and prevent any additional charges once the dollar amount totals XX amount. (I.e. Limit charges to same credit card in a day to no more than USD$4000. (Customer to instruct threshold amount.) 

 

	 	(d)	Enhancement to the Duplicate PNR and Duplicate Segment Processes. An enhancement will be completed to enable the process to look for additional elements to
determine true duplicate including the addition of using name, credit card number and ticket number and coupon number, and even fake email addresses such as viajes@yahoo.com, viajes@hotmail.com (as an examples) Other example is that
this process must have the ability to find and extract all PNRs with the same credit card numbers and different names. Goal is to allow Customer to find PNRs with patterns of duplication when PNRs are booked and / or on day of departure – as
close to flight time as possible. 

  

	 	(i)	An additional Customer requirement that will be met upon cutover through this process is to allow this process to search and identify “duplicates” on the same
day that occur more than FOUR times – such as ... find all purchases or “buys” that are made on the same day either by same passenger name, or where same credit card has been used for payment, searching all points of sale.

  

	 	(e)	Auto Teletype Reject Message Queue Processing. The Auto Teletype Reject Queue Process offers a configurable robotic application to automatically work a vast
majority of an airline’s teletype reject messages on a queue. 

  

	 	(i)	This process allows a set of User-configured rules to be applied to each teletype reject message type. Each TTY message is read as it falls on the carrier-specified
queue and is then actioned according to the rules defined by the User. Although 100% of all teletype reject message scenarios cannot be automatically processed, airlines can now automate the processing of a significantly higher percentage of the
most common reject scenarios and reduce the amount of resources previously allocated to manually work TTY reject queues. 

 In addition, Customer is entitled to the following new processes planned for delivery in 2010 for the entire Revenue Integrity Community including: 

 

	 	(a)	Group Booking Management Process. The Group Booking Management Process will assist Customer in managing group travel PNRs and enforce group fare and ticketing
policies. The new process will allow an Airline to apply group time limits for multiple things such as: 

  

	 	(i)	Deposit receipt date (% milestones and full receipt) 

  

	 	(ii)	Receipt of Passenger Names 

  

	 	(iii)	Messaging to booking source 

  

	 	(iv)	Enforcement of group numbers for contracted price 

  

	 	(v)	Enforcement of ticketing dates 

Additionally the process will perform checks to review that all passengers within a group are ticketed at the right fare, the number of
passengers at that fare meets contract requirements, and audit the actual fare ticketed with that booked. 
  

	 	(b)	 Enhanced Restricted Credit Card process matching. This process is to be enhanced to include the automatic comparison of credit card numbers
shown and used in Customer PNRs to those known credit card numbers found on the Industry credit card Blacklist. If credit card number is found to match any black listed numbers (or numbers uploaded into Revenue Integrity by Customer from their own
managed lists) then the process will make an entry to inhibit check in and alert specific Customer staff via email and / or queuing of PNR. The process will also need to send a SSR message to the booking source (agency) to “contact
airline”. Customer will require the matched traveler to pay cash at the 

  

					
	Confidential	  	Page 47	  	

	 	
airport in order to travel. This process must have the ability to find and extract all PNRs with the same credit card numbers and different names. Customer will have access to this enhanced
Restricted Credit Card process upon its release to the Revenue Integrity User Community in 2010. 

  

	 	(c)	Waitlist Segment Cancellation Process. The Customer will have access to the new Waitlist Segment Cancellation Process, without additional charge, upon the
delivery of this process to the Revenue Integrity User Community in 2010. The process is described as follows: 

  

	 	(i)	The new Waitlist Segment Cancellation Process will automate the ability for airlines to identify PNRs earlier on that have waitlisted segments and either work to clear
those segments or cancel the waitlisted segments out of the PNR to avoid excessive segment fees. Airlines will have the ability to build rules to find all PNRs with waitlisted segments at specified intervals of time prior to flight time and:

  

	 	(ii)	Cancel waitlist segments at least 72 hours (or at any time interval) before departure 

 

	 	(iii)	Track and notify travel agents of unacceptable waitlist practices and alert commercial department of violations for possible fee assessment 

 

	 	(iv)	Identify waitlisted segments where clearance is unlikely and cancel to avoid GDS fee 

 

	 	(v)	Reduce total waitlist expenses by automatically cancelling all waitlisted segments in all PNRs X days before departure 

 

	 	(vi)	Track and report details on all waitlisted segments cancelled 

  

	 	(d)	Sabre Real Time Revenue Integrity. As part of our SabreSonic roadmap for Revenue Integrity, Customer will have access to the Real Time Revenue Integrity solution
upon its release to the Revenue Integrity User Community. The newly enhanced Real Time Revenue Integrity solution will apply your airline’s process rules, enforce policies, send alerts and take directed actions within minutes after a PNR has
been created or modified to protect and maximize revenue right up to flight departure time.

	14.	MERCHANDISING SERVICES 

  

	14.1	Branded Fares: 

 The
SabreSonic® Branded Fares solution provides the capability to create and sell “brands” (a.k.a. fare families) by categorizing different fare classes (a.k.a. Reservation Booking Designator) into a brand with associated
attributes. The following modules/features are provided with this option: 
  

	 	(a)	 Sabre Merchandising Manager
TM – an online GUI based application that allows the Customer to define which fare classes are mapped to a particular
brand and to define which fare basis codes are excluded from a brand. Sabre Merchandising Manager also allows the Customer to define what attributes are associated with the branded fare and then distribute this information as a textual
message via a web service. 

  

	 	(b)	Enhanced SabreSonic Sell features – include the capability to shop by branded fares. Branded fare shopping is included with Interact and with SabreSonic Web
(if included in the Agreement). The SabreSonic Branded Fare shopping service can also be delivered as a web service or integrated with SabreSonic direct sales channels. 

 

	 	(c)	Branded Fare Fulfillment features – include the capability to print branded fares on the boarding coupon, within the check-in GUI, and on the passenger
manifest 

  

	14.2	Ancillary or “ala carte” Sales: 

  

	 	(a)	The Ancillary Sales solution provides the Customer the capability to define up to 99 ancillaries. Ancillaries are tracked with airline specified Special Service
Requests (SSR’s), which are defined in the SSR Inventory solution, which the Customer can access via an online GUI. The first ancillary covered under this framework is “pay for excess bags” (scheduled for 2Q
2010). Configuration work may be required in SabreSonic direct channels (i.e. SabreSonic Web and Interact) to support the display of new ancillaries, and SabreSonic Check-in work may be required to support fulfillment of new
ancillaries. Additional ancillaries will be rolled out as per the SabreSonic CSS roadmap. 

  

	14.3	Pay for Preferred Seat: 

The “Pay for Preferred Seat” solution provides the capability to charge for pre-reserving a specific seat. The solution can
be configured to charge for pre-reserving at seat at time of booking creation or extending the requirement to charge for reserving a seat through the check-in period. 
 This option provides additional capabilities in the following modules: 
  

	 	(a)	SabreSonic Seat Map – an additional seat block (P Block) is used to designate seats that require a fee to pre-reserve. Seat blocks are set by the
Customer using the SabreSonic Command GUI. The seat fee can vary by seat type and market. 

  

	 	(b)	SabreSonic Inventory – provides a capability to control whether the P Blocked seats can be pre-reserved based on the fare class of the purchased ticket. For
example, based on the fare class of the purchased ticket, P Blocked seats can be restricted from selection, pre-reserved for a fee, or pre-reserved at no charge.

 

	 	(c)	SabreSonic Web (if included in the Agreement) – provides the capability to show a seat map and which seats require a fee payment in order to pre-reserve
them, as well as showing what the fee amount is. SabreSonic Web also supports the collection and fulfillment of the ancillary fee for pre-reserving the “preferred seat”. 

 

	 	(d)	Interact Reservation and Check-in GUI – provides the capability to charge a fee to pre-reserve “preferred seats”, either at time of booking, or at
the check-in (if Customer elects to charge for selecting a “preferred seat” during the check-in period). For the seat fees collected at time of booking, an automated robot is provided to handle the fulfillment of the purchase and
speed up the booking process. Graphical indicators are used on the Interact availability screen to indicate to the reservation agent which flights have “preferred seats”. Capabilities also exist to override the fees for
“preferred seats” and specify a reason for the override. 

  

					
	Confidential	  	Page 50	  	

	 	(e)	 Sabre Virtually
ThereTM – provides additional documentation on the seat information line indicating when a “preferred seat” has been selected, as well as the amount paid for the “preferred seat” on the
electronic receipt. 

  

	 	(f)	SabreSonic Web Check-in (if included in the Agreement) – provides additional capabilities to prompt the passenger about the existence of “preferred
seats” and to collect a fee for “preferred seats” at time of web check-in using a major credit card. 

  

	 	(g)	SabreSonic Kiosk Check-in (if included in the Agreement) – provides additional capabilities to prompt the passenger about the existence of “preferred
seats” and to collect a fee for “preferred seats” at time of kiosk check-in using a major credit card.
