 W I T N E S S E T H 
 WHEREAS, Travelport LLC, (f/k/a TDS
Investor Corporation), a Delaware limited liability company (the “Issuer”), has heretofore executed and delivered to the Trustee an indenture, dated as of August 23, 2006, as supplemented by Supplemental Indenture No. 1

Senior Euro Floating Rate Notes due 2014 and $450,000,000 aggregate principal amount of 9 7/8% Senior Dollar Fixed Rate Notes due 2014 (together, the “Notes”); 

WHEREAS, pursuant to Section 9.01 of the Indenture, which does not require the consent of the Holders, the Guaranteeing Subsidiary
desires to enter into this Supplemental Indenture pursuant to which the Guaranteeing Subsidiary, jointly and severally with all Guarantors named in the Indenture (which for the avoidance of doubt shall include the guaranteeing subsidiaries party to
the supplemental indentures thereto), agrees to pay and shall fully and unconditionally guarantee all of the Issuer’s obligations under the Indenture and all of the Notes pursuant to the Indenture on the terms and conditions set forth herein
(the “Guarantee”); and 
 WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to
execute and deliver this Supplemental Indenture. 
 NOW THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt of which is hereby acknowledged, the parties mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows: 

(1) Capitalized Terms. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture.

 (2) Agreement to Guarantee. The Guaranteeing Subsidiary hereby agrees as follows: 

(a) Along with all Guarantors named in the Indenture, to jointly and unconditionally unconditionally guarantee to each
Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, the Notes or the obligations of the Issuer hereunder or thereunder,
that: 
 (i) the principal of and interest, premium and Additional Interest, if any, on the Notes will be
promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Issuer to the Holders or the
Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 
 (ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that the same will be promptly paid in full when due or performed in accordance with the terms of
the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors and the Guaranteeing Subsidiary shall be
jointly and severally obligated to pay the same immediately. This is a guarantee of payment and not a guarantee of collection. 







 (b) The obligations hereunder shall be unconditional, irrespective of the
validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment
against the Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. 

(c) The following are hereby waived: diligence, presentment, demand of payment, filing of claims with a court in the event
of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest, notice and all demands whatsoever. 
 (d) This Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes, the Indenture and this Supplemental Indenture, and the Guaranteeing Subsidiary accepts
all obligations of a Guarantor under the Indenture. 
 (e) If any Holder or the Trustee is required by any court
or otherwise to return to the Issuer, the Guarantors (including the Guaranteeing Subsidiary), or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuer or the Guarantors, any amount paid either to the
Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. 
 (f) The Guaranteeing Subsidiary shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations
guaranteed hereby. 
 (g) As between the Guaranteeing Subsidiary, on the one hand, and the Holders and the
Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 of the Indenture for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any 

  
 2 








 
declaration of acceleration of such obligations as provided in Article 6 of the Indenture, such obligations (whether or not due and payable) shall forthwith become due and payable by the
Guaranteeing Subsidiary for the purpose of this Guarantee. 
 (h) The Guaranteeing Subsidiary shall have the
right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under this Guarantee. 
 (i) Pursuant to Section 10.02 of the Indenture, after giving effect to all other contingent and fixed liabilities that are relevant under any applicable Bankruptcy or fraudulent conveyance laws, and
after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under Article 10 of the Indenture, this new Guarantee
shall be limited to the maximum amount permissible such that the obligations of the Guaranteeing Subsidiary under this Guarantee will not constitute a fraudulent transfer or conveyance. 

(j) This Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or
against the Issuer for liquidation, reorganization, should the Issuer become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of the Issuer’s assets, and
shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be
restored or returned by any obligee on the Notes and Guarantee, whether as a “voidable preference”, “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment or
any part thereof, is rescinded, reduced, restored or returned, the Note shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned. 

(k) In case any provision of this Guarantee shall be invalid, illegal or un-enforceable, the validity, legality, and
enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
 (l) This
Guarantee shall be a general unsecured senior obligation of the Guaranteeing Subsidiary, ranking pari passu with any other future Senior Indebtedness of the Guaranteeing Subsidiary, if any. 

(m) Each payment to be made by the Guaranteeing Subsidiary in respect of this Guarantee shall be made without set-off,
counterclaim, reduction or diminution of any kind or nature. 
 (3) Execution and Delivery. The Guaranteeing Subsidiary agrees
that the Guarantee shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes.

one or more related transactions, to any Person unless:

 (B) the

Guarantor or the Issuer.

(by merger or otherwise) of the Capital Stock of the Guaranteeing Subsidiary (including any sale, exchange or transfer), after which the Guaranteeing Subsidiary is no longer a Restricted Subsidiary or all or substantially all the assets of the
Guaranteeing Subsidiary which sale, exchange or transfer is made in compliance with the applicable provisions of the Indenture;
