		2.	Closing Date Deliverables. At or prior to the Closing, Sponsor and the Insiders shall deliver to Acquiror and the Company a
duly executed copy of all Transaction Documents to which such Sponsor Party is contemplated to be a party, in substantially the forms

that (i) paragraph 7(a) shall apply to the Sponsor Shares, in lieu of “Founder Shares” or “Ordinary Shares issuable

ledger or other books and records in the case of uncertificated securities) that they are subject to the contractual restrictions on transfer
imposed pursuant to this paragraph 3 or paragraphs 7(a) or 7(b) of the Insider Letter, then, upon the termination of the applicable Lock-up
Period, Acquiror shall promptly (and in any event within three (3) Business Days) take all actions reasonably necessary (including sending
an instruction letter to Acquiror’s transfer agent) to cause such legend to be removed.

 

		4.	Vesting and Forfeiture of Sponsor Shares.

 

		a.	Designation. Of the Sponsor Shares, 13,631,318 are referred to herein as “Immediately Vested Sponsor Shares”
and, subject to the last sentence of this paragraph 4.a, the remaining 6,713,932 are referred to herein as “Vesting Sponsor Shares.”
Subject to the last sentence of this paragraph 4.a, of the Vesting Sponsor Shares, (i) 3,356,966 are referred to herein as “$12.50
Threshold Shares,” and (ii) 3,356,966 are referred to herein as “$15.00 Threshold Shares.” Notwithstanding
anything to the contrary set forth herein, if after the date hereof, Sponsor enters into a Syndication Transfer, pursuant to which Sponsor
agrees to Transfer (which may be effectuated as a forfeiture to Acquiror and reissuance by Acquiror) Acquiror Cayman Class B Ordinary
Shares (which are converted into Domesticated Acquiror Class X Common Stock and subsequently converted into Domesticated Acquiror Class
A Common Stock in connection with the Transactions) (such shares, the “Syndicate Shares”)
to such equity investor, then upon consummation of such Syndication Transfer the amounts set forth above as “Vesting Sponsor Shares”
and “$15.00 Threshold Shares” shall be deemed reduced by the amount of the Syndicate Shares; provided that if the number
of Syndicate Shares is greater than the number of $15.00 Threshold Shares, then the amount set forth above as $12.50 Threshold Shares
shall next be deemed reduced by such excess; provided, further, that if such excess described in the previous proviso is
greater than the $12.50 Threshold Shares, the amount set forth above as Immediately Vested Sponsor Shares shall next be deemed reduced
by such further excess. The parties hereto agree that all Syndicate Shares, once Transferred (or forfeited and reissued) to such equity
investor, shall not be subject to any of the provisions of this Letter Agreement, including paragraphs 3 and 4.

 

    3

     

    

 

		b.	Immediately Vested Sponsor Shares. From and after the Closing, the Immediately Vested Sponsor Shares
shall be deemed to have vested and shall not be subject to forfeiture under this Letter Agreement.

 

		c.	$12.50 Threshold Shares. Effective as of and conditioned upon the Closing, the $12.50 Threshold Shares shall be deemed unvested
and become subject to forfeiture as set forth herein. If, at any time during the Vesting Period, the VWAP of Domesticated Acquiror Class
A Common Stock is greater than or equal to $12.50 for any twenty (20) Trading Days within a period of thirty (30) consecutive Trading
Days (a “$12.50 Trigger Event”), (i) the $12.50 Threshold Shares shall be deemed to have vested and shall cease to
be subject to forfeiture under this Letter Agreement and (ii) Acquiror shall promptly (and in any event, within three (3) Business Days)
(x) pay to the holder(s) of the $12.50 Threshold Shares all dividends and other distributions set aside pursuant to paragraph 4.h and
(y) take all actions reasonably necessary to cause any and all legends set forth on certificates representing the $12.50 Threshold Shares
(or notations in Acquiror’s stock ledger or other books and records, if such shares are uncertificated) pursuant to paragraph 4.i
hereto to be removed.

 

		d.	$15.00 Threshold Shares. Effective as of and conditioned upon the Closing, the $15.00 Threshold Shares shall be deemed unvested
and become subject to forfeiture as set forth herein. If, at any time during the Vesting Period, the VWAP of Domesticated Acquiror Class
A Common Stock is greater than or equal to $15.00 for any twenty (20) Trading Days within a period of thirty (30) consecutive Trading
Days (a “$15.00 Trigger Event”), (i) the $15.00 Threshold Shares shall be deemed to have vested and shall cease to
be subject to forfeiture under this Letter Agreement and (ii) Acquiror shall promptly (and in any event within three (3) Business Days)
(x) pay to the holder(s) of the $15.00 Threshold Shares all dividends and other distributions set aside pursuant to paragraph 4.h and
(y) take all actions reasonably necessary to cause any and all legends set forth on certificates representing the $15.00 Threshold Shares
(or notations in Acquiror’s stock ledger or other books and records, if such shares are uncertificated) pursuant to paragraph 4.i
hereto to be removed.

 

    4

     

    

 

		e.	Change of Control. Notwithstanding anything to the contrary set forth herein, in the event that there is a Change of Control
after the Closing and prior to the end of the Vesting Period:

 

		i.	to the extent it has not already occurred, a $12.50 Trigger Event shall be deemed to occur (and the actions contemplated by paragraph
4.c shall be required to occur) on the day immediately prior to the occurrence of such Change of Control if the value of the per share
consideration to be received by the holders of Domesticated Acquiror Class A Common Stock in such Change of Control is greater than or
equal to $12.50; provided, that if such Change of Control is an acquisition of Acquiror by merger, business combination or otherwise
in which the holders of Domesticated Acquiror Class A Common Stock receive only cash consideration for their shares at a price less than
$12.50 per share (a “Non-Qualifying $12.50 Change of Control”), then the obligations in paragraphs 4.c, 4.d, this paragraph
4.e.i and 4.e.ii shall terminate and no longer apply effective upon such Non-Qualifying $12.50 Change of Control; and

 

		ii.	to the extent it has not already occurred, a $15.00 Trigger Event shall be deemed to occur (and the actions contemplated by paragraph
4.d shall be required to occur) on the day immediately prior to the occurrence of such Change of Control if the value of the per share
consideration to be received by the holders of Domesticated Acquiror Class A Common Stock in such Change of Control is greater than or
equal to $15.00; provided, that if such Change of Control is an acquisition of Acquiror by merger, business combination or otherwise
in which the holders of Domesticated Acquiror Class A Common Stock receive only cash consideration for their shares at a price less than
$15.00 per share (a “Non-Qualifying $15.00 Change of Control”), then the obligations in paragraph 4.d and this paragraph
4.e.ii shall terminate and no longer apply effective upon such Non-Qualifying $15.00 Change of Control.

 

provided, further,
that (A) in each of the foregoing clauses i. and ii. of this paragraph 4.e, to the extent the per share consideration to be received
by holders of Domesticated Acquiror Class A Common Stock in such Change of Control includes contingent consideration or property
other than cash, the Acquiror Board shall determine the value of such consideration in good faith (valuing any such consideration
payable in publicly traded securities, on a per-security basis, at the VWAP of such security over the twenty (20) consecutive
Trading Day period ending on (and including) the second Business Day prior to the date of the entry into the binding definitive
agreement providing for the consummation of such Change of Control, if there be such an agreement, or the date of such Change of
Control, if there is no such agreement); (B) any determination by the Acquiror Board with respect to any matters contemplated by, or
related to, this paragraph 4.e, including the value of the per share consideration to be received by holders of Domesticated
Acquiror Class A Common Stock in any Change of Control, shall be made in good faith and shall be final and binding on the parties
hereto; and (C) if the consideration in a Change of Control is equity securities of the surviving company or one of its Affiliates
that are (or will be at the closing of such Change of Control) publicly traded, any remaining unvested Vesting Sponsor Shares (not
otherwise vested pursuant to this paragraph 4, including in accordance with clause (A) of this proviso) shall not be forfeited and
instead shall be converted into similar equity securities offered in such Change of Control and shall remain subject to the
remaining applicable vesting triggering events set forth herein (as may be equitably adjusted to take into account the structure and
consideration provided for such Change of Control). For avoidance of doubt, the provisions in clauses i. and ii. of this paragraph
4.e may apply to a single Change of Control, such that both the $12.50 Trigger Event and the $15.00 Trigger Event may be deemed to
occur in connection with such single Change of Control if the conditions set forth in both clauses i. and ii. are satisfied.

 

    5

     

    

 

		f.	Equitable Adjustments. The number of shares set forth in paragraph 4.a and the Domesticated Acquiror Class A Common Stock price
targets set forth in paragraphs 4.c, 4.d and 4.e, as applicable, shall be equitably adjusted for stock splits, reverse stock splits, dividends
(cash or stock), reorganizations, recapitalizations, reclassifications, combinations or other like changes or transactions with respect
to the Domesticated Acquiror Class A Common Stock occurring after the Closing (other than the Transactions).

 

		g.	Forfeiture.

 

		i.	If the $12.50 Trigger Event has not occurred or been deemed to have occurred prior to the end of the Vesting Period, the obligations
in paragraphs 4.c, 4.d and 4.e shall terminate and no longer apply and all holder(s) of the $12.50 Threshold Shares and $15.00 Threshold
shares shall, immediately thereafter, irrevocably forfeit and surrender such shares to Acquiror for no consideration as a contribution
to the capital of Acquiror (including for purposes of Section 118 of the Code).

 

		ii.	If the $15.00 Trigger Event has not occurred or been deemed to have occurred prior to the end of the Vesting Period, the obligations
in paragraphs 4.d and 4.e.ii shall terminate and no longer apply and all holder(s) of the $15.00 Threshold Shares shall, immediately thereafter,
irrevocably forfeit and surrender such shares to Acquiror for no consideration as a contribution to the capital of Acquiror (including
for purposes of Section 118 of the Code).

 

		h.	Rights of Holder(s) of Vesting Sponsor Shares. The registered holder(s) of any Vesting Sponsor Shares that remain unvested
prior to the expiration of the Vesting Period shall be entitled to all of the rights of ownership thereof, including the right to vote
and receive dividends and other distributions in respect of such Vesting Sponsor Shares. Notwithstanding the foregoing, to the extent
that any dividends or other distributions are paid in cash in respect
of Vesting Sponsor Shares with a payment date prior to the earlier of (x) the vesting of such Vesting Sponsor Shares upon the $12.50
Trigger Event or $15.00 Trigger Event, as applicable, or (y) the expiration of the Vesting Period shall be set aside by Acquiror
and shall be paid to the holder(s) thereof upon the vesting of such Vesting Sponsor Shares at, as applicable, the $12.50 Trigger Event
or $15.00 Trigger Event (if at all).

 

    6

     

    

 

		i.	Restrictions on Transfer; Legends. Sponsor agrees that it shall not Transfer any unvested Vesting Sponsor Shares held by Sponsor
prior to the date such Vesting Sponsor Shares become vested pursuant to this paragraph 4, except to a permitted transferee pursuant to
a Permitted Transfer. Certificates or book entries representing unvested Vesting Sponsor Shares shall bear a legend referencing that they
are subject to forfeiture and contractual restrictions on transfer imposed pursuant to paragraph 3 of this Letter Agreement, and any transfer
agent for Domesticated Acquiror Class A Common Stock will be given appropriate stop transfer orders with respect to such unvested Vesting
Sponsor Shares.

 

		5.	Sponsor Assistance. For a period of two (2) years following the Closing Date, Sponsor agrees to
use commercially reasonable efforts to work with Apollo Portfolio Performance Solutions to offer and encourage Apollo Management Holdings,
L.P. and its affiliated funds’ portfolio companies to use the Company’s services.

 

		6.	Use of “Apollo” Name. From and after the Closing, Acquiror shall cease all use of the
name “Apollo” (the “Apollo Name”), including as part of its corporate name, provided that the foregoing
shall not prohibit Acquiror and its Affiliates from using the Apollo Name (i) in a neutral, non-trademarked manner to describe the history
of Acquiror's business, (ii) in internal legal and business records, (iii) in ordinary course disclosures, communications and external
documents provided to their respective directors, officers, employees, investors, advisors, agents and representatives or (iv) as required
by applicable Law. To the extent that Acquiror owns any rights, title or interest in or to the Apollo Name, whether by operation of law
or otherwise, at Closing, Acquiror hereby irrevocably transfers and assigns any and all such rights to Sponsor. Following the Closing
Date, if any further action on the part of Acquiror is necessary to carry out the provisions of this paragraph 6, Acquiror shall use commercially
reasonable efforts to take such action upon Sponsor’s reasonable request and at Sponsor’s cost and expense.

 

		7.	Termination. Except as otherwise expressly set forth in this Letter Agreement, this Letter
                                                                Agreement shall terminate upon the earliest to occur of (a) the later of (i) the earlier of (x) a $15.00 Trigger Event and (y) the
                                                                expiration of the Vesting Period and, in either case, the performance by Acquiror and Sponsor of the last obligation required to be
                                                                performed by it following a $15.00 Trigger Event or the expiration of the Vesting Period, as applicable and (ii) the expiration of
                                                                the Founder Shares Lock-up Period, (b) the termination of the Transaction Agreement in accordance with its terms prior to the
                                                                Closing or (c) the time this Letter Agreement is terminated upon the mutual written agreement of the parties hereto; provided,
                                                                that, if the Closing occurs, paragraphs 5 and 6 hereto shall survive the termination of this Letter Agreement
in accordance with its terms. Upon such termination, this Letter Agreement (except paragraphs 5 and 6) shall forthwith become void and
have no further force or effect, without any liability or other obligation on the part of any party hereto to any Person in respect of
the transactions contemplated hereby, and no party shall have any claim against any other party hereto (and no Person shall have any rights
against such party), whether under contract, tort or otherwise, with respect to the subject matter hereof; provided, that no such
termination shall relieve any party hereto of any liability arising in respect of any willful and material breach of this Letter Agreement
occurring prior to such termination. Paragraphs 5, 6 and this paragraph 7 shall survive the termination of this Letter Agreement.

 

    7

     

    

 

		8.	Miscellaneous.

 

		a.	Governing Law. This Letter Agreement, and all claims or causes of action based upon, arising out
of, or related to this Letter Agreement or the transactions contemplated hereby, shall be governed by, and construed in accordance with,

		i.	Any Action based upon, arising out of or related to this Letter Agreement or the transactions contemplated
hereby must be brought in the Court of Chancery of the State of Delaware and any state appellate court therefrom within the State of Delaware

any state or federal court within the State of Delaware), and each of the parties hereto irrevocably and unconditionally (i) consents
and submits to the exclusive jurisdiction of each such court in any such Action, (ii) waives any objection it may now or hereafter have
to personal jurisdiction, venue or to convenience of forum, (iii) agrees that all claims in respect of the Action shall be heard and determined

		c.	Assignment. Neither this Letter Agreement nor any part thereof shall (a) be assigned by any of

this Letter Agreement, they shall take any actions necessary to render the remaining provisions of this Letter Agreement valid and enforceable
to the fullest extent permitted by Law and, to the extent necessary, shall amend or otherwise modify this Letter Agreement to replace
any provision contained herein that is held invalid or unenforceable with a valid and enforceable provision giving effect to the intent
of the parties hereto.

AGREEMENT

 

NOW, THEREFORE, in consideration
of the foregoing and the mutual agreements contained herein, and intending to be legally bound hereby, the Parties hereby agree as follows:

 

ARTICLE
I

shareholder COVENANTS 

 

Section 1.1           
Special Resolutions, Consents, Approvals, etc. Each Shareholder agrees that it shall (solely as to itself and not any other
Shareholder), and shall cause any other holder of record of any of such Shareholder’s Covered Shares to:

 

(a)         
during the Interim
Period, validly execute, return and otherwise grant any action by written consent, special resolution or other approval, or vote or cause
to be voted at any meeting of shareholders of the Company (and appear or otherwise cause its Covered Shares to be counted as present
thereat for purposes of quorum) (and any adjournment thereof or in any other circumstance in which the vote, consent or the approval
of any of the Shareholders is sought), in each case, with respect to all of its Covered Shares entitled to vote or consent on matters
put to a vote or consent, as applicable, in favor of any such consent, special resolution or other approval as may be required under
the Organizational Documents of the Company or applicable Law or otherwise sought with respect to the Transaction Agreement or the Transactions
(including, without limitation, in order to effect the transactions set forth in Section 2.1 of the Transaction Agreement); and

 

(b)         
during the Interim Period, validly execute, return and otherwise grant any action by written consent, special resolution or other
approval, or vote or cause to be voted at any meeting of shareholders of the Company (and appear or otherwise cause its Covered Shares
to be counted as present thereat for purposes of quorum) (and any adjournment thereof or in any other circumstance in which the vote,
consent or the approval of any of the Shareholders is sought), in each case, with respect to all of its Covered Shares, against (i) any
Competing Transaction and (ii) any other proposal, agreement or action that would reasonably be expected to (A) prevent or nullify, or
materially delay or materially impair the ability of the Company to perform its obligations under, any provision of this Agreement or
the Transaction Agreement, (B) result in any of the conditions to the Closing in Article VIII of the Transaction Agreement not being
satisfied or (C) result in a breach of any covenant, representation or warranty or other obligation or agreement of the Shareholders
contained in this Agreement.

 

For purposes of this Agreement, a Shareholder shall be deemed to “own”
or to have “ownership” of a security if such Shareholder (i) is the record owner of such security; or (ii) is the “beneficial
owner” (within the meaning of Rule 13d-3 under the Exchange Act) of such security.

 

Section 1.2           
No Interim Period Transfers. No Shareholder shall, during the Interim Period (except, in each case, pursuant to the Transaction
Agreement), (a) sell or assign, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise
dispose of or agree to dispose of, directly or indirectly (including by merger (including by conversion into securities or other consideration),
by tendering into any tender or exchange offer, by testamentary disposition, by operation of Law or otherwise), either voluntarily or
involuntarily, any of its Covered Shares (each, a “Transfer”), (b) enter into any swap or other arrangement that Transfers
to another, in whole or in part, any of the economic consequences of ownership of any of its Covered Shares, whether any such transaction
is to be settled by delivery of such securities, in cash or otherwise, or (c) publicly announce any intention to effect any transaction
specified in the foregoing clauses (a) or (b); provided, however, that the foregoing shall not prohibit a Compliance Transfer, provided,
that any Shareholder effecting such Compliance Transfer shall (or, if such Compliance Transfer is pursuant to Section 2.2.2 or Section
2.2.3 of the Existing Shareholders Agreement, shall use best efforts to) obtain an agreement from the transferee in writing, reasonably
satisfactory in form and substance to Acquiror, to assume all of the obligations of the transferring Shareholder under, and be bound
by all of the terms of, this Agreement.

 

Section 1.3           
Expedia Shares. Expedia and Juniper acknowledge and agree that, for purposes of this Agreement, prior to the Expedia Transfer,
all equity interests in Juniper or any other Juweel Entity (as defined in the Existing Shareholders Agreement) held by Expedia or any
of its Affiliates shall be subject to the provisions of Section 1.2 of this Agreement as if they were “Covered Shares”. To
the extent Expedia or any of its Affiliates acquires or otherwise becomes the record or beneficial owner of equity interests of the Company
(including as a result of the Expedia Transfer), such equity interests shall be “Covered Shares” for all purposes of this
Agreement. Each of Expedia and Juniper, represent and warrant that, as of the date hereof, the class and number of equity interests in
Juniper and any other Juweel Entity and the number of Company Non-Voting Ordinary Shares indirectly owned by Expedia are set forth opposite
its name on Schedule I attached hereto.

 

     2

     

    

 

Section 1.4           
Post-Closing Equity Adjustment; Post-Closing Lock-Up.

 

(a)         
Each Shareholder hereby acknowledges that it has read the Transaction Agreement, including Sections 2.7(f) (Earnout) and
2.8 (Closing Egencia Acquisition) (collectively, the “Adjustment Provisions”), and understands that the Adjustment
Provisions provide that such Shareholder’s equity interests or rights to equity interests in the Company and Acquiror may be subject
to reservation, redemption, cancellation and adjustment (in number and/or terms) following the Closing, as and to the extent set forth
therein.

 

(b)         
Subject to the last sentence of this Section 1.4(b), each Shareholder hereby agrees that it shall not, until the one hundred eightieth
(180th) day following the Closing Date (the “UW Lock-up Release Date”), Transfer any equity securities of Acquiror
or the Company (including shares of, or other derivative securities relating to shares of, Domesticated Acquiror Class A Common Stock
issued on account of an exchange under the Exchange Agreement occurring between the Closing and the UW Lock-Up Release Date) other than
(i) pursuant to a Compliance Transfer, provided that in the event of such Transfer, the transferee shall be required to agree to the
terms of this Agreement (other than in respect of a transfer pursuant to Section 2.2.2 or Section 2.2.3 of the Existing Shareholders
Agreement in which case the transferor shall be required to use reasonable best efforts to cause the transferee to agree to the terms
of this Agreement); or (ii)(A) with the prior written consent of a majority of the Independent Nominees (as defined in the Shareholders
Agreement) and (B) the applicable transferee agreeing in writing, in form and substance reasonably satisfactory to Acquiror, to assume
all of the obligations of the transferring Shareholder under, and be bound by all of the terms of, this Agreement, to the extent applicable
following the Closing (the foregoing clauses (i) and (ii) collectively, the “Transfer Restriction Exceptions”). Notwithstanding
the foregoing, if the final determination of the Post-Closing Equity Adjustment (as defined in the Equity Contribution Agreement) has
not occurred prior to the expiration of the UW Lock-Up Release Date, then each Shareholder hereby agrees that it shall retain and not
Transfer at least five percent (5%) of each class of securities of each of Acquiror and of the Company that it receives in connection
with the Closing from the UW Lock-Up Release Date until the completion of the implementation of the adjustments set forth in Section
2.8(b) of the Transaction Agreement (or the payment and receipt of the settlement of the Post-Closing Equity Adjustment pursuant to Section
2.8(d) of the Transaction Agreement), other than Transfers pursuant to the Transfer Exceptions (provided, that the applicable transferee
has agreed to be subject to this transfer restriction to the extent required by the preceding sentence, unless the transferring Shareholder
continues to own at least five percent (5%) of each class of securities of each of Acquiror and of the Company that it receives in connection
with the Closing, in which case such transferee shall not be required to comply with this sentence).

 

Section 1.5           
Transaction Agreement Covenants. During the Interim Period, each Shareholder agrees to be bound by and comply with Section
5.4 (No Solicitation by the Company) and Section 7.8 (Publicity) of the Transaction Agreement (and any relevant definitions
used in any such sections) as if such Shareholder was the Company with respect to such provisions. It is expressly acknowledged and agreed
that nothing contained in this Agreement shall limit or otherwise apply to disclosure by Alder or its Affiliates in connection with supervisory
examinations by or communications with bank regulatory authorities with jurisdiction over Alder or its affiliates.

 

Section 1.6           
No Inconsistent Agreement. Each Shareholder hereby agrees and represents and covenants that such Shareholder has not entered
into, and shall not enter into, any agreement that would restrict, limit or interfere with the performance of such Shareholder’s
obligations hereunder.

 

Section 1.7           
Update of Schedule I. If any Shareholder acquires record or beneficial ownership of any Covered Shares or, in the case
of Expedia, equity interests of Juniper following the date hereof (or becomes aware, following the date hereof, of its record or beneficial
ownership of any Covered Shares or, in the case of Expedia, equity interests of Juniper as of the date hereof, which shares are not already
set forth on Schedule I), such Shareholder shall promptly notify Acquiror in writing (email being sufficient), and Schedule I shall be
updated to reflect such Shareholder’s ownership of such additional Covered Shares or, in the case of Expedia, equity interests
of Juniper. For the avoidance of doubt, no Shareholder shall be required to provide any such notification to the extent provided by the
Company in respect of Covered Shares issued in connection with any draw down under the Company Existing Equity Commitment Documents.

 

Section 1.8           
Project Runway. During the Interim Period, Alder shall, and shall cause its Affiliates to, use its and their respective
reasonable best efforts to enter into definitive agreements with the Company consistent in all material respects with the Project Runway
Term Sheet set forth on Section 5.5 of the Company Disclosure Letter (such term sheet, the “Project Runway Term Sheet”),
other than any deviations from such Project Runway Term Sheet not materially less favorable to Acquiror, the Company and its Subsidiaries
(such definitive agreements, collectively, the “Project Runway Agreements”). Alder acknowledges and agrees that the
Project Runway Term Sheet is a binding agreement on the parties thereto to comply with the terms and provisions thereof until the Project
Runway Agreements have been fully executed and are in full force and effect. During the Interim Period, without the prior written consent
of Acquiror, Alder shall not, and shall not permit any of its Affiliates to, unless and until the Project Runway Agreements have been
fully executed and are in full force and effect, terminate, waive or materially amend or modify any provisions of the Project Runway
Term Sheet or any provisions of the letter agreement by and among Alder, Juniper and the Company dated as of the date hereof to which
the Project Runway Term Sheet is attached (a copy of which has been delivered to Acquiror prior to the date hereof) with respect to the
Project Runway Term Sheet.

 

Section 1.9           
Closing Date Deliverables. On the Closing Date, each Shareholder shall deliver to Acquiror and the Company a duly executed
copy of the Shareholders Agreement, the Acquiror Class B Common Stock Distribution Agreement, the Exchange Agreement and the Registration
Rights Agreement.

ARTICLE
II

REPRESENTATIONS AND WARRANTIES

 

Section 2.1           
Representations and Warranties of the Shareholders. Each Shareholder represents and warrants as of the date hereof to Acquiror
(severally and not jointly and solely with respect to itself and not with respect to any other Shareholder) as follows:

 

(a)         
Organization; Due Authorization. Such Shareholder (i) is duly organized, validly existing and in good standing under the
Laws of the jurisdiction in which it is incorporated, formed, organized or constituted, and (ii) has all requisite corporate, limited
liability company or other power and authority to execute and deliver this Agreement, to perform its obligations hereunder and to consummate
the transactions contemplated hereby. The execution, delivery and performance by such Shareholder of this Agreement and the consummation
of the transactions contemplated hereby have been duly and validly authorized and approved by all necessary corporate, limited liability
company or other organizational actions on the part of such Shareholder. This Agreement has been duly and validly executed and delivered
by such Shareholder and assuming that this Agreement constitutes the legal, valid and binding obligation of each other party hereto,
this Agreement constitutes a legal, valid and binding obligation of such Shareholder, and is enforceable against such Shareholder in
accordance with the terms hereof, subject to the Bankruptcy and Equity Exception.

 

(b)              
Ownership. As of the date hereof, such Shareholder is the record and beneficial owner (as defined in the Securities Act)
of, and has good title to, all of such Shareholder’s equity interests as set forth opposite such Shareholder’s name on Schedule
I attached hereto, and there exist no Liens or any other limitation or restriction (including any restriction on the right to vote,
sell or otherwise dispose of such equity interests (other than transfer restrictions under the Securities Act)) affecting any such equity
interests, other than Liens pursuant to (i) this Agreement, (ii) the Company’s Organizational Documents (or Juniper’s Organizational
Documents in the case of Expedia), (iii) the Transaction Agreement, or (v) any applicable securities Laws. Such Shareholder’s equity
interests as set forth opposite such Shareholder’s name on Schedule I attached hereto are the only equity interests in the
Company (or Juniper, in the case of Expedia) owned of record or beneficially by such Shareholder on the date of this Agreement, and none
of such Shareholder’s equity interests in the Company (or Juniper, in the case of Expedia) are subject to any proxy, voting trust
or other agreement or arrangement with respect to the voting of such equity interests, except as provided hereunder or in the Company’s
Organizational Documents or Juniper’s Organizational Documents. Such Shareholder does not hold or own any rights to acquire (directly
or indirectly) any equity interests of the Company (or Juniper, in the case of Expedia) or any equity interests convertible into, or
which can be exchanged for, equity interests of the Company (or Juniper, in the case of Expedia).

 

(c)              
No Conflicts. The execution and delivery of this Agreement by such Shareholder do not, and the consummation of the transactions
contemplated hereby and the performance by such Shareholder of its obligations hereunder will not, (i) conflict with or result in a violation
of the Organizational Documents of such Shareholder, or (ii) require any consent or approval that has not been given or other action
that has not been taken by any Person (including under any Contract binding upon such Shareholder or such Shareholder’s Covered
Shares or, in the case of Expedia, equity interests of Juniper), in each case, to the extent the absence of such consent, approval or
other action would prevent, enjoin or materially delay the performance by such Shareholder of its obligations under this Agreement.

 

(d)              
Litigation. There are no Actions pending, or to the knowledge of such Shareholder, threatened against such Shareholder,
which in any manner challenges or seeks to prevent, enjoin or materially delay the performance by such Shareholder of its obligations
under this Agreement.

 

(e)              
Brokerage Fees. Except as set forth in Section 3.23 of the Company Disclosure Letter, no broker, finder, investment banker
or similar intermediary is entitled to any broker’s, finder’s or similar fee or other commission or compensation in connection
with the Transactions based on any arrangement made by such Shareholder, for which Acquiror, the Company or any of their respective Subsidiaries
may become liable.

 

(f)               
Acknowledgment. Each Shareholder understands and acknowledges that Acquiror is entering into the Transaction Agreement
in reliance upon such Shareholder’s execution and delivery of this Agreement.

Termination; Non-Survival of Representations and Warranties.

 

(a)         
This Agreement shall terminate upon the earliest to occur of (i) the termination of the Transaction Agreement in accordance with
its terms prior to the Closing or (ii) the time this Agreement is terminated upon the written agreement of the Parties. Upon such
termination, this Agreement shall forthwith become void and have no further force or effect, without any liability or other obligation
on the part of any Party to any Person in respect of the transactions contemplated hereby, and no Party shall have any claim against
any other Party (and no Person shall have any rights against such Party), whether under contract, tort or otherwise, with respect to
the subject matter hereof; provided, however, that the termination of this Agreement shall not relieve any Party from liability arising
in respect of any willful and material breach of this Agreement occurring prior to such termination. This ARTICLE III shall survive
the termination of this Agreement.

 

(b)         
None of the representations, warranties or covenants contained in this Agreement or in any certificate or other writing delivered
pursuant hereto shall survive the Closing, except for (i) those covenants and agreements contained herein that by their terms expressly
apply in whole or in part after the Closing and then only with respect to any breaches occurring after the Closing and (ii) this ARTICLE
III.

 

Section 3.2           
Governing Law. This Agreement, and all claims or causes of action based upon, arising out of, or related to this Agreement
or the transactions contemplated hereby, shall be governed by, and construed in accordance with, the Laws of the State of Delaware, without
giving effect to principles or rules of conflict of laws to the extent such principles or rules would require or permit the application
of the Laws of another jurisdiction.

 

Section 3.3           
Jurisdiction; Waiver of Jury Trial.

 

(a)         
Any Action based upon, arising out of or related to this Agreement or the transactions contemplated hereby must be brought in
the Court of Chancery of the State of Delaware and any state appellate court therefrom within the State of Delaware (unless the Court
of Chancery of the State of Delaware shall decline to accept jurisdiction over a particular matter, in which case, in any state or federal
court within the State of Delaware), and each of the Parties irrevocably and unconditionally (i) consents and submits to the exclusive
jurisdiction of each such court in any such Action, (ii) waives any objection it may now or hereafter have to personal jurisdiction,
venue or to convenience of forum, (iii) agrees that all claims in respect of the Action shall be heard and determined only in any such
court, (iv) agrees not to bring any Action arising out of or relating to this Agreement or the transactions contemplated hereby in any
other court and (v) agrees to accept service of process in any such Action if given in the same manner for giving notices under Section
3.8 or in any other manner permitted by applicable Law. Nothing herein contained shall be deemed to affect the right of any Party
to serve process in any manner permitted by Law or to commence Actions or otherwise proceed against any other Party in any other jurisdiction,
in each case, to enforce judgments obtained in any Action brought pursuant to this Section 3.3(a).

 

(b)         
EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY ACTION WHICH MAY ARISE UNDER THIS AGREEMENT AND THE TRANSACTIONS IS LIKELY TO INVOLVE
COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY, UNCONDITIONALLY AND VOLUNTARILY WAIVES ANY RIGHT
SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY ACTION, SUIT OR PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING
TO THIS AGREEMENT OR ANY OF THE TRANSACTIONS.

 

Section 3.4           
Assignment. Neither this Agreement nor any part thereof shall (a) be assigned by any of the Shareholders without the prior
written consent of Acquiror or (b) be assigned by Acquiror without the prior written consent of the Shareholders. Any such assignment
without such consent shall be null and void. Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit
of the Parties and their respective successors and permitted assigns.

 

     5

     

    

 

Section 3.5           
Enforcement. The Parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate
remedy would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms
or were otherwise breached. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions to prevent breaches
of this Agreement and to specific enforcement of the terms and provisions of this Agreement prior to the valid termination of this Agreement
in accordance with Section 3.1, in addition to any other remedy to which any Party is entitled at law or in equity. In the event
that any Action shall be brought in equity to enforce the provisions of this Agreement, no Party shall oppose the granting of specific
performance and other equitable relief on the basis, or allege, and each Party hereby waives the defense, that there is an adequate remedy
at law, and each Party agrees to waive any requirement for the securing or posting of any bond in connection therewith. The Parties acknowledge
and agree that the right of specific enforcement is an integral part of the transactions contemplated hereby and without that right,
neither Party would have entered into this Agreement.

 

Section 3.6           
Amendment. Subject to the provisions of applicable Law, this Agreement may be amended or modified in whole or in part,
only by a duly authorized agreement in writing executed in the same manner as this Agreement and which makes reference to this Agreement;
provided, however, that no amendment may be made to Section 1.3, this Section 3.6 or Section 3.12 without the prior
written consent of APSG Sponsor, L.P., a Cayman Islands exempted limited partnership (“Sponsor”).

 

Section 3.7           
Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction,
the other provisions of this Agreement shall remain in full force and effect. The Parties further agree that if any provision contained
herein is, to any extent, held invalid or unenforceable in any respect under the Laws governing this Agreement, they shall take any actions
necessary to render the remaining provisions of this Agreement valid and enforceable to the fullest extent permitted by Law and, to the
extent necessary, shall amend or otherwise modify this Agreement to replace any provision contained herein that is held invalid or unenforceable
with a valid and enforceable provision giving effect to the intent of the parties.
