PLEASE CAREFULLY REVIEW AND FOLLOW THE INSTRUCTIONS BELOW AND ATTACHED TO THIS FORM.

If you are a recipient of both Eligible Legacy Options and Eligible BCA Options, and you wish to exchange all your Eligible Options, please check the box which states, “Accept the Amended Exchange Offer to exchange all Eligible Options.” If you are a recipient of only Legacy Options and wish to exchange your Eligible Legacy Options, or if you wish to exchange only your Eligible Legacy Options (but not your BCA Options), please check the box which states, “Accept the Amended Exchange Offer to exchange all Eligible Legacy Options only.” If you are a recipient of only BCA Options and wish to exchange your Eligible BCA Options, or if you wish to exchange only your Eligible BCA Options (but not your Legacy Options), please check the box which states “Accept the Amended Exchange Offer to exchange all Eligible BCA Options only.” If you do not wish to exchange any Options, please check the box which states, “Reject the Amended Exchange Offer and retain all Eligible Options.”

If you tender Eligible Legacy Options in the Amended Exchange Offer, all of your Legacy Options that are in-the-money at the Expiration Time will be automatically exercised. Your in-the-money Legacy Options would be exercised on a cashless basis and net-settled for applicable taxes (based on the closing price of our Class A Common Stock on the Closing Date).

All Eligible Legacy Options and all Eligible BCA Options, as applicable, tendered for exchange must be tendered in whole. If you check the box next to “Reject the Amended Exchange Offer and retain all Eligible Options”, all Eligible Options will remain outstanding subject to their original terms, and no New RSUs will be granted to you in exchange for your Eligible Options.

If you make no election, or do not return this Election Form before the Expiration Time, you will retain your Eligible Legacy Options or your Eligible BCA Options, or both as applicable, subject to their original terms, and no New RSUs will be granted to you.

Please submit your initial acceptance and / or rejection by completing this Election Form, which once submitted will automatically be forwarded to GBTG, so that we receive it before 11:59 p.m. Eastern Standard Time, on Thursday, January 26, 2023 (or such later date as may apply if the Amended Exchange Offer is extended).

AGREEMENT TO THE TERMS OF ELECTION

To:

Global Business Travel Group, Inc. (“GBTG”)

666 3rd Avenue, 4th Floor

New York, New York 10017

Email: MIPExchange@amexgbt.com

By signing and submitting this Election Form, I acknowledge and agree that:

1.	Any election that I submitted prior to GBTG’s filing of the Amended Offer Documents (as defined below) with the SEC on January 11, 2023 was automatically deemed void upon filing of the Amended Offer Documents.

I have received from GBTG the Amended and Restated Offer to Exchange Eligible Options for New Restricted Stock Units, including the Summary Term Sheet - Questions and Answers, dated January 11, 2023 (collectively, the “Amended Offer Documents”), and upon making an election herein, I agree to all of the terms and conditions of the Amended Offer Documents.

If I have checked the respective box on the Election Form, then I tender to GBTG for exchange all of my Eligible Legacy Options or all of my Eligible BCA Options, or both as applicable, and understand that, upon acceptance by GBTG, the Election Form (including this Agreement to the Terms of Election and Instructions to Election Form attached below) will constitute a binding agreement between GBTG and me.

If I validly tender all Eligible Legacy Options or all Eligible BCA Options, or both as applicable, for exchange and all such Eligible Options are accepted by GBTG, such tendered Eligible Options will automatically be cancelled by GBTG in exchange for the grant of one or more New RSUs with the applicable New RSU Terms described in the Amended Offer Documents.

5.	If I am not eligible to participate in the exchange with respect to Eligible Legacy Options, any election I make to tender my Eligible Legacy Options, pursuant to this form or otherwise, will be treated as void.

6.	If I am not eligible to participate in the exchange with respect to Eligible BCA Options, any election I make to tender my Eligible BCA Options, pursuant to this form or otherwise, will be treated as void.

If I elect to participate in the Amended Exchange Offer, my election shall constitute my agreement, without further action required by any party, to the terms of the applicable form of RSU award agreement attached as an exhibit to the Tender Offer Statement on Schedule TO filed by GBTG with the U.S. Securities and Exchange Commission on December 13, 2022, immediately (and automatically) effective at the Expiration Time.

If I elect to participate in the Amended Exchange Offer with respect to my Eligible Legacy Options, my election shall constitute my agreement to automatically exercise, as of the Expiration Time, all (but not less than all) of my outstanding Legacy Options to purchase Class A common stock of GBTG that are in-the-money at the Expiration Time, on a cashless net-exercise and net-settlement for taxes basis, in each case, based on the closing price of a share of Class A Common Stock on the Closing Date.

To remain eligible to tender Eligible Options for exchange pursuant to the Amended Exchange Offer, I must remain an Eligible Participant and must not have received a notice of termination nor given a notice of resignation with respect to my employment prior to the Expiration Time, which is currently scheduled to be 11:59 p.m., Eastern Standard Time, on Thursday, January 26, 2023, unless extended. I understand that if my employment with GBTG ceases (or if I give or receive notice of my employment termination) prior to the Expiration Time, GBTG will not accept my Eligible Options for exchange and I or my estate or beneficiaries, as the case may be, will retain my Eligible Options subject to their original terms and conditions. I understand and agree that any New RSUs will be subject to the terms of GBTG’s 2022 Equity Incentive Plan and the applicable RSU award agreement, including with respect to vesting and forfeiture, and that except as provided in those documents, if I cease providing services to GBTG prior to the time any New RSUs I receive have vested, then I will forfeit any unvested New RSUs.

10.	Neither the ability to participate in the Amended Exchange Offer nor actual participation in the Amended Exchange Offer will be construed as a right to continued employment or service with GBTG.

11.	My election is entirely voluntary, and I am aware that I may change or withdraw my decision to tender my Eligible Legacy Options or Eligible BCA Options, or both as applicable, at any time until the Expiration Time,

as described in the Instructions to Election Form. I understand that this decision to tender my Eligible Options will be irrevocable as of 11:59 p.m., Eastern Standard Time, on Thursday, January 26, 2023, unless the Amended Exchange Offer is extended. Participation in the Amended Exchange Offer is entirely my decision and should be made based on my personal circumstances. GBTG has not authorized any person to make any recommendation on its behalf as to whether or not I should participate in the Amended Exchange Offer.

12.	I may receive certain future confirmation letters or other communications from GBTG in connection with the Amended Exchange Offer, including a communication confirming that GBTG has received the Election Form and whether GBTG ultimately accepts or rejects this Election Form.
