consult with its tax, legal and other advisors with respect thereto and hereto. Each Sponsor shall be bound by and comply with Section

Sponsor was an original signatory to the Merger Agreement with respect to such provisions.

     

     

    

 

Section 1.2         
No Interim Period
Transfers. Each Sponsor shall not, during the Interim Period (except, in each case, pursuant to the Merger Agreement or otherwise

(any transaction specified in clause (i), (ii) or (iii), a “Transfer”); provided, however, that

of this Agreement to the same extent as if they constituted the Quantum Common Stock or Quantum Warrants owned by such Sponsor as of the
date hereof. Notwithstanding any of the foregoing to the contrary, and without limiting Section 1.5(a), no Sponsor shall cause,
or permit any Affiliate of Sponsor to cause, any New Securities to be created or issued except as expressly permitted by the Merger Agreement

Specific Performance.
The Parties agree that irreparable damage (for which monetary damages, even if available, would not be an adequate remedy) may occur,
and that the Parties may not have 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 seek
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 each 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 to seek
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 Quantum, the Company, Monex and each 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.

 

Section 3.8

notices and other communications hereunder shall be in writing and shall be deemed given if delivered personally, by email (with confirmation

Shareholder is the sole record owner and beneficial owner (within the meaning of Rule 13d-3 under the Exchange Act) of, and has good,
valid and marketable title to, or has a valid proxy to vote, the Shareholder’s Covered Shares, free and clear of any Liens (other

Company Stock (or any securities convertible into shares of Company Stock) or any interest therein.

 

(b) The
Shareholder, except as provided in this Agreement or the Governing Documents of the Company, (i) has full voting power, full power of
disposition and full power to issue instructions with respect to the matters set forth herein, whether by ownership or by proxy, in each

into any agreement or undertaking that is otherwise inconsistent with, or would interfere with, or prohibit or prevent it from satisfying,
its obligations pursuant to this Agreement, and has no knowledge and is not aware of any such agreement or undertaking.

 

(c) The
Shareholder affirms that it (A) is a legal entity duly organized, validly existing and, to the extent such concept is applicable, in good
standing under the Laws of the jurisdiction of its organization and (B) has all requisite corporate or other power and authority to, and
has taken all corporate or other action necessary in order to, execute, deliver and perform its obligations under this Agreement and to
consummate the transactions contemplated hereby. This Agreement has been duly executed and delivered by the Shareholder and, subject to
the due execution and delivery of this Agreement by each of the Company and Quantum, constitutes a legally valid and binding agreement

bankruptcy Laws or other similar Laws affecting creditors’ rights and general principles of equity affecting the availability of
specific performance and other equitable remedies).

 

(d) Other
than the filings, notices and reports pursuant to, in compliance with or required to be made under the Exchange Act and the Financial
Instruments and Exchange Act of Japan (Act No. 25 of April 13, 1948, as amended), no filings, notices, reports, consents, registrations,
approvals, permits, waivers, expirations of waiting periods or authorizations are required to be obtained by the Shareholder from, or
to be given by the Shareholder to, or to be made by the Shareholder with, any Governmental Authority in connection with the execution,
delivery and performance by the Shareholder of this Agreement, the consummation of the transactions contemplated hereby or the Transactions.

 

(e) The
execution, delivery and performance of this Agreement by the Shareholder does not, and the consummation of the transactions contemplated
hereby and the Transactions will not, constitute or result in (i) a breach or violation of, or a default under, the Governing Documents
of the Shareholder, (ii) a breach or violation of, a termination (or right of termination) of or a default under, the loss of any benefit
under, the creation, modification or acceleration of any obligations under or the creation of a Lien on any of the properties, rights
or assets of the Shareholder pursuant to any Contract binding upon the Shareholder or, assuming (solely with respect to performance of
this Agreement and the transactions contemplated hereby), compliance with the matters referred to in Section 5(d), under any applicable
Law to which the Shareholder is subject, (iii) any change in the rights or obligations of any party under any Contract legally binding
upon the Shareholder or (iv) any violation of applicable Law, except, in the case of clauses (ii), (iii) or (iv) directly above, for any
such breach, violation, termination, default, creation, acceleration or change that would not, individually or in the aggregate, reasonably
be expected to prevent or materially delay or impair the Shareholder’s ability to perform its obligations hereunder or to consummate
the transactions contemplated hereby or the Transactions.

 

(f) As
of the date of this Agreement, there is no Action pending against the Shareholder or, to the knowledge of the Shareholder, threatened
against the Shareholder that, in any manner, questions the beneficial or record ownership of the Shareholder’s Covered Shares or
the validity of this Agreement, or challenges or seeks to prevent, enjoin or materially delay the performance by the Shareholder of its
obligations under this Agreement.

 

    3

     

    

 

(g) Except
as described on Section 6.23 of the Company Disclosure Letter, no broker, finder, investment banker or other Person is entitled to any

arrangements made by the Shareholder, for which the Company or any of its Affiliates may become liable.

 

(h) The
Shareholder understands and acknowledges that Quantum is entering into the Merger Agreement in reliance upon the Shareholder’s execution

or warranties with respect to the actions of any of the Company Related Parties, and (C) any breach by the Company of its obligations

and supersede all prior agreements and understandings, both written and oral, between the Parties with respect to the subject matter hereof.

 

15. No
Third-Party Beneficiaries. The Shareholder hereby agrees that its representations, warranties and covenants set forth herein
are solely for the benefit of Quantum and the Company 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

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.

 

16. 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 16(b).

 

    9

     

    

 

(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.

 

17. Assignment;
Successors. Neither this Agreement nor any of the rights, interests or obligations hereunder shall (a) be assigned by any of
the Shareholder, in whole or in part (whether by operation of Law or otherwise), without the prior written consent of Quantum and the
Company or (b) be assigned by Quantum or the Company, in whole or in part (whether by operation of law or otherwise), without the prior
written consent of the Company (in the case of an attempted assignment by Quantum) or Quantum (in the case of an attempted assignment
by the Company). 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.

 

18. 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 the Company’s obligations under Section 1 and
the Shareholder’s obligations under Section 2, 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.

 

19. 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.

 

    10

     

    

 

20. 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.

 

21. Interpretation

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. The term “or” is not exclusive.

as a Shareholder or Proxy Holder. Notwithstanding anything herein to the contrary, the Shareholder is signing this Agreement
solely in the Shareholder’s capacity as the sole shareholder of the Company, and not in any other capacity, and this Agreement shall
not limit, prevent or otherwise affect the actions of the Shareholder or any Affiliate or Representative thereof, or any of their respective
Affiliates, in his, her or its capacity, if applicable, as an officer or director of the Company (or any Subsidiary of the Company) or
any other Person, including in the exercise of his, her or its fiduciary duties as a director or officer of the Company or any Subsidiary
