of any of the Company Related Parties and (iii) any breach by the Company of its obligations under Section 5.6(a) of the Business

execute and deliver such additional documents and take all such further action as may be reasonably necessary to effect the actions and
consummate the transactions contemplated by this Agreement. The Shareholder further agrees not to commence or participate in, and to take

by and construed in accordance with the Laws of the State of Delaware, without giving effect to any choice of law or conflict of law provision
or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Law of any jurisdiction other
than the State of Delaware.

 

(b)              
Each of the parties irrevocably and unconditionally submits to the exclusive jurisdiction of the Chancery Court of the State of
Delaware (or, if the Chancery Court of the State of Delaware declines to accept jurisdiction, any state or federal court sitting in the

in any such court that any such Proceeding has been brought in an inconvenient forum. Each party hereby irrevocably and unconditionally
waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, in any Proceeding claim, demand, action
or cause of action against such party (A) arising under this Agreement or (B) in any way connected with or related or incidental to the
dealings of the parties in respect of this Agreement or any of the transactions contemplated hereby, (I) any claim that such party
is not personally subject to the jurisdiction of the courts as described in this Section 15 for any reason, (II) that
such party or such party’s property is exempt or immune from the 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

    9

     

    

 

16.             
 Assignment; Successors. No party hereto shall assign this Agreement or any part hereof without the prior written consent
of the other parties. Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the parties hereto and
their respective permitted successors and assigns. Any attempted assignment in violation of the terms of this Section 16 shall

17.             
Non-Recourse. This Agreement may only be enforced against, and any claim or cause of action based upon, arising out of,
or related to this Agreement or the transactions contemplated hereby may only be brought against, the entities that are expressly named
as parties hereto, and then only with respect to the specific obligations set forth herein with respect to such party. Except to the extent
a named party to this Agreement (and then only to the extent of the specific obligations undertaken by such named party in this Agreement),
(a) no past, present or future director, officer, employee, incorporator, member, partner, shareholder, affiliate, agent, attorney, advisor
or representative or affiliate of any named party to this Agreement and (b) no past, present or future director, officer, employee, incorporator,
member, partner, shareholder, affiliate, agent, attorney, advisor or representative or affiliate of any of the foregoing shall have any
liability (whether in contract, tort, equity or otherwise) for any one or more of the representations, warranties, covenants, agreements
or other obligations or liabilities of any one or more of SPAC, the Company or the Shareholder under this Agreement of or for any claim
based on, arising out of, or related to this Agreement or the transactions contemplated hereby.

 

18.             
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 the parties do not perform their obligations under the provisions of this Agreement in accordance
with its specified terms or otherwise breach such provisions. The parties acknowledge and agree that (a) the parties shall be entitled
to an injunction, specific performance, or other equitable relief, to prevent breaches of this Agreement and to enforce specifically the
terms and provisions hereof, including the Shareholder’s obligations to vote its Covered Shares as provided in this Agreement, without
proof of damages, prior to the valid termination of this Agreement, this being in addition to any other remedy to which they are entitled
under this Agreement, and (b) the right of specific enforcement is an integral part of the transactions contemplated by this Agreement
and without that 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 or that an award
of specific performance is not an appropriate remedy for any reason at Law or equity. The parties acknowledge and agree that any party
seeking an injunction to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in
accordance with this Section 18 shall not be required to provide any bond or other security in connection with any such injunction.

 

19.              Severability.
Whenever possible, each provision of this Agreement will be interpreted in such a manner as to be effective and valid under
applicable Law, but if any term or other provision of this Agreement is held to be invalid, illegal or unenforceable under
applicable Law, all other provisions of this Agreement shall remain in full force and effect so long as the economic or legal
substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such
determination that any term or other provision of this Agreement is invalid, illegal or unenforceable under applicable Law, the
parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as
closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally

This Management Incentive Agreement (this “Agreement”)
is made and entered into as of March 23, 2022, among Hub Cyber Security (Israel) Ltd., a company organized under the laws of the State
of Israel (the “Company”), Mount Rainier Acquisition Corp. (“SPAC”), and the member of management
of the Company listed on Schedule A hereto (the “Recipient”, and together with the Company, the “Parties”).

 

WHEREAS, the Company, Rover Merger Sub, Inc.,
a Delaware corporation and wholly owned subsidiary of the Company (“Merger Sub”), and Mount Rainier Acquisition Corp.,
a Delaware corporation (“SPAC”), have entered into that certain Business Combination Agreement, dated March ___, 2022 (the
“Business Combination Agreement”), pursuant to which Merger Sub will merge with and into SPAC, with SPAC surviving
such merger as a wholly owned subsidiary of the Company (the “Business Combination”);

 

WHEREAS, upon the consummation the transactions
contemplated by the Business Combination Agreement (the “Closing”), the Ordinary Shares, no par value, of the Company
(“Company Shares”) will be listed for trading on Nasdaq; and

 

WHEREAS, the Company intends to promote the interests
of the Company and retain certain individuals who are integral to the success of the Company to contribute to the progress, growth and
profitability of the Company by providing certain members of the management of the Company, including the Recipient with an opportunity
to participate in the Company’s future by granting them certain incentives as specified herein.

 

NOW, THEREFORE, in consideration of the foregoing
and the mutual and dependent covenants hereinafter set forth, the Parties agree as follows:

1.             Definitions.

 

Capitalized
terms used herein without definition shall have the meanings assigned thereto in the Business Combination Agreement.

 

“Change
of Control Consideration” means the amount per Company Share to be received by the holders
thereof in connection with a Change of Control Transaction, with any non-cash consideration valued as determined by the value ascribed
to such consideration by the parties to such transaction.

 

“Change
of Control Transaction” means any transaction or series of related transactions (a) under
which any Person(s), directly or indirectly, acquires or otherwise purchases (i) another Person or any of its Affiliates or (ii) all or
substantially all of the assets, businesses or Equity Securities of another Person, whether by merger, consolidation, tender offer, recapitalization,
purchase or issuance of Equity Securities, tender offer or otherwise),.

 

“Incentive
Period” means the period beginning on, in the case of non-interested persons, the
Closing Date and, in the case of interested persons, the later of (i) the Closing Date and (ii) the date when the obligations of the
Company hereunder are approved by the requisite majority of shareholders of the Company if such shareholder approval is required
under applicable Laws, and, in each case terminating on the third anniversary of the Closing Date.

 

     

     

    

 

“Incentive
Shares” means the number of Company Shares to be issued to the Recipient as set forth on Exhibit
A hereto.

 

“VWAP”
means, with respect to any security, for each trading day, the daily volume-weighted average price (based on such trading day) of such
security on Nasdaq as reported by Bloomberg Financial L.P. using the AQR function.

 

2.             Incentive Trigger. Subject to the terms
of the 2022 HUB Management Incentive Plan described in Section 4 and the Services Requirements described in Section 5, if, during the
Incentive Period, the VWAP of the Company Shares on Nasdaq for any period of at least 10 trading days (which may or may not be consecutive)
out of 20 consecutive trading days is greater than 180% of the Company Share Value (such price the “Incentive Target”
and such occurrence, the “Trigger”), the Company shall promptly (but in any event within five (5) Business Days of
the date of Trigger) issue to the Recipient the Incentive Shares for no consideration.

 

3.             Acceleration Event; Change of Control Transaction.

 

(a)           In the event, during the Incentive Period and prior to the Trigger, there is a Change of Control Transaction that will result in
the holders of Company Shares receiving a Change on Control Consideration equal to or greater than the Incentive Target, immediately prior
to the consummation of such Change of Control Transaction, (i) the Trigger shall be deemed to have occurred and (ii) the Company shall
promptly (but in any event within five (5) Business Days from the consummation of such Change of Control Transaction) issue the Incentive
Shares to the Recipient.

 

(b)           The Incentive Shares issued pursuant to Section 3(a) shall, upon their issuance to the Recipient, be fully paid and free
and clear of all Liens other than applicable securities Laws restrictions. If the Change of Control Consideration paid or payable to the
holders of Company Shares in connection with the first Company Change of Control to occur during the Incentive Period and prior to the
Trigger is less than the Incentive Target, then (i) the Trigger shall not be deemed to have occurred and (ii) no Incentive Shares shall
be issuable to the Recipient.

 

(c)           In the event that a definitive agreement with respect to a Change of Control Transaction is executed by the Company prior to, and
remains pending at the end of, the Incentive Period, for purposes of Section 3(a), the Incentive Period shall be deemed to have
been extended until the earlier of (i) the consummation of such Change of Control Transaction and (ii) the termination of such Change
of Control Transaction.

 

    2

     

    

 

(d)           The
right of the Recipient to receive Incentive Shares upon a Change of Control Transaction shall expire if a Trigger has not occurred prior
to the consummation of the first Change of Control Transaction to occur after the Closing.

 

4.             Management Incentive Plan. Each Recipient acknowledges and agrees that the terms and rights of such Recipient hereunder
are subject to the approval of the 2022 HUB Management Incentive Plan (“Plan”) by the Board of Directors and shareholders
of the Company (if required), and to the terms of such Plan, as approved.

 

5.             Service Requirements. The issuance to Recipient of the Incentive Shares or any portion thereof shall be contingent upon
the performance of the Recipient and other factors, including the continued employment or other service of the Recipient by HUB during
the Incentive Period and as of the Trigger Date, in each case as shall be more fully set forth in the Plan.

 

6.             Notices. All notices, requests, claims, demands and other communications among the parties shall be in writing and shall
be deemed to have been duly given (i) when delivered in person, (ii) seven (7) days after posting in the United States mail having been

laws of the State of Israel, without giving effect to any choice or conflict of law provision or rule (whether of the State of Israel
or any other jurisdiction) that would cause the application of Laws of any jurisdiction other than those of the State of Israel. Each
of the parties irrevocably and unconditionally submits to the exclusive jurisdiction of the district courts of Tel-Aviv, Jaffa.

 

14.           Counterparts. This Agreement may be executed in two or more counterparts,
