execution of judgment or otherwise) and (c) that (i) the Action in any such court is brought in an inconvenient forum,

not performed in accordance with the terms hereof, and, accordingly, that the parties shall be entitled to an injunction or injunctions
to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof in the Court
of Chancery of the State of Delaware or, if that court does not have jurisdiction, any court of the United States located in the
State of Delaware without proof of actual damages or otherwise, in addition to any other remedy to which they are entitled at law
or in equity as expressly permitted in this Agreement. Each of the parties hereby further waives (a) any defense in any action

of GX Common Stock or GX Warrants evidences in a writing reasonably satisfactory to the Company such transferee’s agreement
to be bound by and subject to the terms and provisions hereof to the same extent as the Sponsor.

 

Section 1.2 
New Shares. In the event that (a) any shares of GX Common Stock, GX Warrants or other equity securities of GX are
issued to a Sponsor after the date of this Sponsor Agreement pursuant to any stock dividend, stock split, recapitalization, reclassification,
combination or exchange of shares of GX Common Stock or GX Warrants of, on or affecting the shares of GX Common Stock or GX Warrants
owned by such Sponsor or otherwise, (b) a Sponsor purchases or otherwise acquires beneficial ownership of any shares of GX Common
Stock, GX Warrants or other equity securities of GX after the date of this Sponsor Agreement, or (c) a Sponsor acquires the right
to vote or share in the voting of any shares of GX Common Stock or other equity securities of GX after the date of this Sponsor
Agreement (such shares of GX Common Stock, GX Warrants or other equity securities of GX, collectively the “New Securities”),
then such New Securities acquired or purchased by such Sponsor shall be subject to the terms of this Sponsor Agreement to the same
extent as if they constituted the shares of GX Common Stock or GX Warrants owned by such Sponsor as of the date hereof.

 

Section 1.3 
Closing Date Deliverables. On the Closing Date, the Sponsor Holdco and the Director Holders (as defined therein)
shall deliver to GX and the Company a duly executed copy of that certain Registration Rights Agreement, by and among GX, the Sponsor
Holdco, the Target Holders and the Investor Stockholders (as defined therein), in substantially the form attached as Exhibit A

Section 1.4 
Sponsor Agreements.

 

(a) 
At any meeting of the shareholders of GX, however called, or at any adjournment thereof, or in any other circumstance in
which the vote, consent or other approval of the shareholders of GX is sought, each Sponsor shall (i) appear at each such meeting
or otherwise cause all of its shares of GX Common Stock to be counted as present thereat for purposes of calculating a quorum and
(ii) vote (or cause to be voted), or execute and deliver a written consent (or cause a written consent to be executed and delivered)
covering, all of its shares of GX Common Stock:

 

(i) 
in favor of each GX Proposal;

 

    2

     

    

 

(ii) 
against any Business Combination Proposal or any proposal relating to a Business Combination Proposal (in each case, other
than the GX Proposals);

 

(iii) 
against any merger agreement or merger (other than the Merger Agreement and the Mergers), consolidation, combination, sale
of substantial assets, reorganization, recapitalization, dissolution, liquidation or winding up of or by GX;

 

(iv) 
against any change in the business, management or GX Board (other than in connection with the GX Proposals); and

 

(v) 
against any proposal, action or agreement that would (A) impede, frustrate, prevent or nullify any provision of this Sponsor
Agreement, the Merger Agreement or any Merger, (B) result in a breach in any respect of any covenant, representation, warranty
or any other obligation or agreement of GX, First Merger Sub or Second Merger Sub under the Merger Agreement, (C) result in any
of the conditions set forth in Article VIII of the Merger Agreement not being fulfilled or (D) change in any manner the dividend
policy or capitalization of, including the voting rights of any class of capital stock of, GX;

 

provided, however, that
such Sponsor shall not vote or provide consent with respect to any of its GX Common Stock or New Securities that have the power
to vote (including, without limitation, by proxy or power of attorney) that are not held by GX’s directors, officers, affiliates
or greater than 5% shareholders of GX, or take any other action, in each case to the extent any such vote, consent or other action
would preclude GX from filing the Registration Statement with the SEC as contemplated by the Merger Agreement. Each Sponsor hereby
agrees that it shall not commit or agree to take any action inconsistent with the foregoing.

 

(b) 
Each Sponsor shall comply with, and fully perform all of its obligations, covenants and agreements set forth in, that certain
Letter Agreement, dated May 20, 2019, by and among the Sponsors and GX (the “Voting Letter Agreement”), including
the obligations of the Sponsors pursuant to Section 1 therein to not redeem any shares of GX Common Stock owned by such Sponsor
in connection with the transactions contemplated by the Merger Agreement.

 

(c) 
During the period commencing on the date hereof and ending on the earlier of the consummation of the Closing and the termination
of the Merger Agreement pursuant to Section 9.01 thereof, each Sponsor shall not modify or amend any Contract between or among
such Sponsor, anyone related by blood, marriage or adoption to such Sponsor or any Affiliate of such Sponsor (other than GX or
any of its Subsidiaries), on the one hand, and GX or any of its Subsidiaries, on the other hand (including, for the avoidance of
doubt, the Voting Letter Agreement) without the Company’s prior written consent.

 

Section 1.5 
Anti-Dilution Waiver. Each Sponsor hereby waives, to the fullest extent permitted by Law, the ability to adjust the
Initial Conversion Ratio (as defined in the GX Certificate of Incorporation) pursuant to Section 4.3(b) of the GX Certificate of
Incorporation in connection with the issuance of additional GX Class A Common Stock in the Transactions. This waiver shall be applicable
only in connection with the Transactions and this Agreement (and any GX Class A Common Stock issued in connection with the Transactions)
and shall be void and of no force and effect following the Expiration Time.

 

    3

     

    

 

Section 1.6 
Binding Effect of Merger Agreement. Each Sponsor shall be bound by and comply with Sections 7.06 (Exclusivity)
and 7.11 (Public Announcements) of the Merger Agreement (and any relevant definitions contained in any such Sections) as
if (a) such Sponsor was an original signatory to the Merger Agreement with respect to such provisions, and (b) each reference to
“GX” in Section 7.06 of the Merger Agreement also referred to each Sponsor.

 

Section 1.7 
Further Assurances. Each Sponsor shall take, or cause to be taken, all actions and do, or cause to be done, all things
reasonably necessary under applicable Laws to consummate the Mergers and the other transactions contemplated by the Merger Agreement
on the terms and subject to the conditions set forth therein and herein.

 

Section 1.8 
No Inconsistent Agreement. Each Sponsor hereby represents and covenants that such Sponsor has not entered into, and

performance of such Sponsor’s obligations hereunder.

REPRESENTATIONS AND WARRANTIES

 

Section 2.1 
Representations and Warranties of the Sponsors. Each Sponsor represents and warrants as of the date hereof to GX
and the Company (solely with respect to itself, himself or herself and not with respect to any other Sponsor) as follows:

 

(a) 
Organization; Due Authorization. If such Sponsor is not an individual, it 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 the execution,
delivery and performance of this Sponsor Agreement and the consummation of the transactions contemplated hereby are within such
Sponsor’s corporate, limited liability company or organizational powers and have been duly authorized by all necessary corporate,
limited liability company or organizational actions on the part of such Sponsor. If such Sponsor is an individual, such Sponsor
has full legal capacity, right and authority to execute and deliver this Sponsor Agreement and to perform his or her obligations
hereunder. This Sponsor Agreement has been duly executed and delivered by such Sponsor and, assuming due authorization, execution
and delivery by the other parties to this Sponsor Agreement, this Sponsor Agreement constitutes a legally valid and binding obligation
of such Sponsor, enforceable against such Sponsor in accordance with the terms hereof (subject to the Remedies Exceptions). If
this Sponsor Agreement is being executed in a representative or fiduciary capacity, the Person signing this Sponsor Agreement has
full power and authority to enter into this Sponsor Agreement on behalf of the applicable Sponsor.

 

    4

     

    

 

(b) 
Ownership. Such Sponsor is the record and beneficial owner (as defined in the Securities Act) of, and has good title
to, all of such Sponsor’s shares of GX Common Stock and GX Warrants, 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 shares of GX Common Stock or GX
Warrants (other than transfer restrictions under the Securities Act)) affecting any such shares of GX Common Stock or GX Warrants,
other than Liens pursuant to (i) this Sponsor Agreement, (ii) the GX Organizational Documents, (iii) the Merger Agreement, (iv)
the Voting Letter Agreement or (v) any applicable securities Laws. Such Sponsor’s shares of GX Common Stock and GX Warrants
are the only equity securities in GX owned of record or beneficially by such Sponsor on the date of this Sponsor Agreement, and
none of such Sponsor’s shares of GX Common Stock or GX Warrants are subject to any proxy, voting trust or other agreement
or arrangement with respect to the voting of such shares of GX Common Stock or GX Warrants, except as provided hereunder and under
the Voting Letter Agreement. Other than the GX Warrants, such Sponsor does not hold or own any rights to acquire (directly or indirectly)
any equity securities of GX or any equity securities convertible into, or which can be exchanged for, equity securities of GX.

 

(c) 
No Conflicts. The execution and delivery of this Sponsor Agreement by such Sponsor does not, and the performance
by such Sponsor of his, her or its obligations hereunder will not, (i) if such Sponsor is not an individual, conflict with or result
in a violation of the organizational documents of such Sponsor 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 Sponsor or such Sponsor’s
shares of GX Common Stock or GX Warrants), in each case, to the extent such consent, approval or other action would prevent, enjoin
or materially delay the performance by such Sponsor of its, his or her obligations under this Sponsor Agreement.

 

(d) 
Litigation. There are no Actions pending against such Sponsor, or to the knowledge of such Sponsor threatened against
such Sponsor, before (or, in the case of threatened Actions, that would be before) any arbitrator or any Governmental Authority,
which in any manner challenges or seeks to prevent, enjoin or materially delay the performance by such Sponsor of its, his or her
obligations under this Sponsor Agreement.

 

(e) 
Brokerage Fees. Except for Credit Suisse Securities (USA) LLC, no broker, finder, investment banker or other Person
is entitled to any brokerage fee, finders’ fee or other commission in connection with the Transactions upon arrangements
made by such Sponsor, for which GX or any of its Affiliates may become liable.

 

(f) 
Affiliate Arrangements. Except as set forth on Schedule II attached hereto, neither such Sponsor nor any anyone
related by blood, marriage or adoption to such Sponsor or, to the knowledge of such Sponsor, any Person in which such Sponsor has
a direct or indirect legal, contractual or beneficial ownership of 5% or greater is party to, or has any rights with respect to
or arising from, any Contract with GX or its Subsidiaries.

 

(g) 
Acknowledgment. Such Sponsor understands and acknowledges that each of GX and the Company is entering into the Merger
Agreement in reliance upon such Sponsor’s execution and delivery of this Sponsor Agreement.

its initial Business Combination within the time period set forth in the Certificate of Incorporation of GX and (c) the written
agreement of the Sponsor, GX, and the Company. Upon such termination of this Sponsor Agreement, all obligations of the parties
under this Sponsor Agreement will terminate, without any liability or other obligation on the part of any party hereto to any Person
in respect hereof or the transactions contemplated hereby, and no party hereto shall have any claim against another (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 Sponsor Agreement shall not relieve any party hereto from liability arising in
respect of any breach of this Sponsor Agreement prior to such termination. This ARTICLE III shall survive the termination
of this Sponsor Agreement.

 

Section 3.2 
Governing Law. This Sponsor Agreement shall be governed by, and construed in accordance with, the Laws of the State

court located in the State of Delaware or any other Delaware state court. The parties hereto hereby (a) irrevocably submit
to the exclusive jurisdiction of the aforesaid courts for themselves and with respect to their respective properties for the purpose
of any Action arising out of or relating to this Sponsor Agreement brought by any party hereto, and (b) agree not to commence
any Action relating thereto except in the courts described above in Delaware, other than Actions in any court of competent jurisdiction
to enforce any judgment, decree or award rendered by any such court in Delaware as described herein. Each of the parties further
agrees that notice as provided herein shall constitute sufficient service of process and the parties further waive any argument
that such service is insufficient. Each of the parties hereby irrevocably and unconditionally waives, and agrees not to assert,
by way of motion or as a defense, counterclaim or otherwise, in any Action arising out of or relating to this Sponsor Agreement
or the transactions contemplated hereby, (a) any claim that it is not personally subject to the jurisdiction of the courts
in Delaware as described herein for any reason, (b) that it or its property is exempt or immune from jurisdiction of any such
court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment
in aid of execution of judgment, execution of judgment or otherwise) and (c) that (i) the Action in any such court is
brought in an inconvenient forum, (ii) the venue of such Action is improper or (iii) this Sponsor Agreement, or the subject
matter hereof, may not be enforced in or by such courts.

 

Section 3.3 
CONSENT TO JURISDICTION AND SERVICE OF PROCESS; WAIVER OF JURY TRIAL. Each of the parties hereto hereby waives to
the fullest extent permitted by applicable Law any right it may have to a trial by jury with respect to any litigation directly
or indirectly arising out of, under or in connection with this Sponsor Agreement or the Transactions. Each of the parties hereto
(a) certifies that no representative, agent or attorney of any other party has represented, expressly or otherwise, that such
other party would not, in the event of litigation, seek to enforce that foregoing waiver and (b) acknowledges that it and
the other hereto have been induced to enter into this Sponsor Agreement and the Transactions, as applicable, by, among other things,
the mutual waivers and certifications in this Section 3.3.

rights, interests or obligations hereunder will be assigned (including by operation of law) without the prior written consent of
the parties hereto.

 

Section 3.5 
Specific Performance. The parties agree that irreparable damage would occur if any provision of this Agreement were
not performed in accordance with the terms hereof, and, accordingly, that the parties shall be entitled to an injunction or injunctions
to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof in the Court
of Chancery of the State of Delaware or, if that court does not have jurisdiction, any court of the United States located in the
State of Delaware without proof of actual damages or otherwise, in addition to any other remedy to which they are entitled at law
or in equity as expressly permitted in this Agreement. Each of the parties hereby further waives (a) any defense in any action
for specific performance that a remedy at law would be adequate and (b) any requirement under any Law to post security or
a bond as a prerequisite to obtaining equitable relief.

 

Section 3.6 
Amendment. This Sponsor Agreement may not be amended, changed, supplemented, waived or otherwise modified or terminated,
except upon the execution and delivery of a written agreement executed by GX, the Company and the Sponsor Holdco.

jurisdiction, the other provisions of this Sponsor Agreement will remain in full force and effect. Any provision of this Sponsor
Agreement held invalid or unenforceable only in part or degree will remain in full force and effect to the extent not held invalid
or unenforceable.
