shall be binding upon, inure to the benefit of and be enforceable by the Parties and their respective successors and permitted assigns.

 

Section
3.5 Specific Performance. The Parties agree that irreparable damage (for which monetary damages, even if available, would not be
an adequate remedy) would occur, and that the Parties would not have any adequate remedy at law, 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 specific performance, an injunction or injunctions, or other equitable relief to prevent breaches or
threatened breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, including the Sponsor’s
obligations under Section 1.5(a), without proof of actual damages or otherwise (and each Party hereby waives any requirement for
the securing or posting of any bond in connection with such remedy), this being in addition to any other remedy to which they are entitled
at law or in equity. Each Party acknowledges and agrees that the right of specific enforcement is an integral part of the transactions
contemplated hereby and that, without such right, none of the Parties would have entered into this Agreement. Each Party agrees that
it will not oppose the granting of specific performance and other equitable relief on the basis that the other Parties have an adequate
remedy at law. In the event of a final non-appealable judgement from a court of competent jurisdiction relating to this Agreement, the
prevailing party in such action shall be entitled to reasonable and documented fees and expenses (including reasonable and documented
attorney’s fees) from the non-prevailing party.

 

Section
3.6 Amendment. This Agreement may not be amended, modified or supplemented in any manner, whether by course of conduct or otherwise,
except by an instrument in writing signed by Thunder Bridge, PubCo, the Company, Monex and the Sponsor charged with such amendment, modification
or supplement.

 

Section
3.7 Severability. If any term or other provision of this Agreement is held by a court of competent jurisdiction or other authority
to be invalid, void, unenforceable or against its regulatory policy, the remainder of the terms and provisions of this Agreement shall
remain in full force and effect and shall in no way be affected, impaired or invalidated. Upon such a determination, the Parties shall
negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable
manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

8. Certain

or enter into any agreement with, or knowingly encourage, respond to, or provide information to, any Person (other than Thunder Bridge,
the Company or any of their respective Affiliates or Representatives in respect of the Transactions) concerning any Acquisition Transaction
or (ii) commence, continue or renew any due diligence investigation regarding, or that is reasonably likely to give rise to or result
in, any offer, inquiry, proposal or indication of interest, written or oral, with respect to, or which is reasonably likely to give rise
to or result in, an Acquisition Transaction; provided, that, the execution, delivery and performance of this Agreement, the Combination
Agreement or the other Transaction Documents and the transactions contemplated hereby shall not be deemed a violation of this Section
8(a). The Equityholder shall, and shall direct its Affiliates and Representatives to, immediately cease any and all existing discussions

of the Company or any officers, directors (in their capacity as such), employees and professional advisors of any of the foregoing (collectively,
the “Company Related Parties”),
(B) the Equityholder, in its capacity as the controlling Shareholder of the Company, makes no representations or warranties with respect
to the actions of any of the Company Related Parties, and (C) any breach by the Company of its obligations under Section 11.04(a) of

Representatives of this Section 8(a)).

 

    6

     

    

 

(b) No Transfers Prior
to Termination Date. The Equityholder shall not, prior to the Termination Date (except, in each case, pursuant to the
Combination Agreement), (i) directly or indirectly sell, transfer, hypothecate, pledge, encumber, assign, hedge, swap, convert or
otherwise dispose of (including by merger (including by conversion into securities or other consideration), by tendering into any
tender or exchange offer, by operation of Law or otherwise), either voluntarily or involuntarily, any of its Covered Securities,
(ii) enter into any Contract or option with respect to any transaction specified in clause (i) or 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 Securities, whether
any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (iii) publicly announce any intention
to effect any transaction specified in clauses (i) or (ii) (any transaction specified in clauses (i), (ii) or (iii), a “Transfer”); provided, however,
that the foregoing shall not prohibit a Transfer to an Affiliate of the Equityholder (each, a “Permitted

Time or the Extension Expiration Time, as applicable.

    11

     

    

 

16. Entire
Agreement; Time of Effectiveness. This Agreement and the Combination Agreement constitute the entire agreement and understanding,
and supersede all prior agreements and understandings, both written and oral, between the Parties with respect to the subject matter hereof.

 

17. No
Third-Party Beneficiaries. The Equityholder and PubCo hereby agree that their representations, warranties and covenants set
forth herein are solely for the benefit of Thunder Bridge in accordance with and subject to the terms of this Agreement, and this Agreement
is not intended to, and does not, confer upon any Person other than the Parties, any rights or remedies hereunder, including the right
to rely upon the representations, warranties and covenants set forth herein, and the Parties hereby further agree that this Agreement
may only be enforced against, and any Action that may be based upon, arise out of or relate to this Agreement, or the negotiation, execution
or performance of this Agreement, may only be made against, the Persons expressly named as parties to this Agreement.

 

18. Governing
Law and Venue; Service of Process; Waiver of Jury Trial.

 

(a) 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 internal Laws of the State of Delaware, including its statute of limitations,
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 or statute of limitations of another jurisdiction.

 

(b) Any
Action based upon, arising out of or related to this Agreement or the transactions contemplated hereby may only be brought in the Court
of Chancery of the State of Delaware or, if such court lacks jurisdiction, the state and federal courts in the State of Delaware, and
each of the Parties irrevocably submits to the exclusive jurisdiction of each such court in any such Action, waives any objection it may
now or hereafter have to personal jurisdiction, venue or to convenience of forum, agrees that all claims in respect of the Action shall
be heard and determined only in any such court, and agrees not to bring any Action arising out of or relating to this Agreement or the
transactions contemplated hereby in any other court. 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 legal proceedings 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 18(b).

 

(c) EACH
OF THE PARTIES HEREBY KNOWINGLY, INTENTIONALLY, VOLUNTARILY AND IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY ACTION BASED
UPON, ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

 

19. Assignment;
Successors. Neither this Agreement nor any of the rights, interests or obligations hereunder shall (a) be assigned by any of
the Equityholder or PubCo in whole or in part (whether by operation of Law or otherwise), without the prior written consent of Thunder
Bridge or (b) be assigned by Thunder Bridge, in whole or in part (whether by operation of law or otherwise), without the prior written
consent of the Equityholder and PubCo. Any such assignment without such consent shall be null and void. This Agreement shall be binding
upon, inure to the benefit of and be enforceable by the Parties and their respective successors and permitted assigns.

 

    12

     

    

 

20. Enforcement.
The Parties agree that irreparable damage (for which monetary damages, even if available, would not be an adequate remedy) would occur,
and that the Parties would not have any adequate remedy at law, 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 specific
performance, an injunction or injunctions, or other equitable relief to prevent breaches or threatened breaches of this Agreement and
to enforce specifically the terms and provisions of this Agreement, including obligations under Sections 1 through 4, without
proof of actual damages or otherwise (and each Party hereby waives any requirement for the securing or posting of any bond in connection
with such remedy), this being in addition to any other remedy to which they are entitled at law or in equity. Each Party acknowledges
and agrees that the right of specific enforcement is an integral part of the transactions contemplated hereby and that, without such right,
none of the Parties would have entered into this Agreement. Each Party agrees that it will not oppose the granting of specific performance
and other equitable relief on the basis that the other Parties have an adequate remedy at Law. In the event of a final non-appealable
judgement from a court of competent jurisdiction relating to this Agreement, the prevailing party in such action shall be entitled to
reasonable and documented fees and expenses (including reasonable and documented attorney’s fees) from the non-prevailing party.

 

21. Severability.
If any term or other provision of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void,
unenforceable or against its regulatory policy, the remainder of the terms and provisions of this Agreement shall remain in full force
and effect and shall in no way be affected, impaired or invalidated. Upon such a determination, the Parties shall negotiate in good faith
to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner in order that
the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

 

22. Counterparts.
This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement, it being understood
that each Party need not sign the same counterpart. Signatures delivered electronically or by facsimile shall be deemed to be original
signatures.

 

23. Interpretation
and Construction. The words “hereof,”
“herein” and “hereunder”
and words of like import used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement.
The descriptive headings used herein are inserted for convenience of reference only and are not intended to be part of or to affect the
meaning or interpretation of this Agreement. References to Sections and Schedules are to Sections and Schedules of this Agreement, respectively,
unless otherwise specified. Any singular term in this Agreement shall be deemed to include the plural, and any plural term the singular.
The definitions contained in this Agreement are applicable to the masculine as well as to the feminine and neuter genders of such term.
Whenever the words “include,”
“includes” or “including”
are used in this Agreement, they shall be deemed to be followed by the words “without
limitation,” whether or not they are in fact followed by those words
or words of like import. “Writing,”
“written” and comparable terms refer to printing, typing
and other means of reproducing words (including electronic media) in a visible form. References to any statute shall be deemed to refer
to such statute as amended from time to time and to any rules or regulations promulgated thereunder. References to any person include
the successors and permitted assigns of that person. References from or through any date mean, unless otherwise specified, from and including
such date or through and including such date, respectively. In the event an ambiguity or question of intent or interpretation arises,
this Agreement will be construed as if drafted jointly by the Parties, and no presumption or burden of proof will arise favoring or disfavoring
any Party by virtue of the authorship of any of the provisions of this Agreement. The term “or”
is not exclusive.
