is being delivered to you in accordance with that certain Agreement and Plan of Merger, dated as of the date hereof (as amended, supplemented,

Islands exempted company (together with its successors, including after the Domestication (as such term is defined in the Merger Agreement),
“SPAC”), Rubicon Technologies, LLC, a Delaware limited liability company (the “Company”),
Ravenclaw Merger Sub LLC, a Delaware limited liability company and a wholly-owned subsidiary of SPAC (“Merger Sub LLC”),
certain blocker merger subsidiaries listed on the signature pages thereto (collectively, the “Merger Sub Incs”
and, together with Merger Sub LLC, “Merger Subs”), certain blocker companies listed on the signature pages thereto
(each a “Blocker Company” and collectively, the “Blocker Companies”) pursuant to which,
among other things, Merger Sub LLC shall be merged with and into the Company (the “Merger” and together with
the other transactions contemplated by the Merger Agreement the “Merger”), and hereby amends and restates in
its entirety that certain letter, dated October 14, 2021, from, Founder SPAC Sponsor LLC, a Delaware limited liability company (the “Sponsor”),
and the undersigned individuals, each of whom is a member of SPAC’s board of directors and/or management team (each, an “Insider”
and collectively, the “Insiders”), to SPAC (the “Prior Letter Agreement”). Certain
capitalized terms used herein are defined in paragraph 7 hereof. Capitalized terms used but not otherwise defined herein shall have the
respective meanings ascribed to such terms in the Merger Agreement.


 


The Sponsor and certain Insiders are currently,
and as of the Closing will be, the record owners of all of the outstanding Founder Shares and outstanding Acquiror Private Placement Warrants,
with the Sponsor and Insider’s ownership as of the date hereof detailed on Schedule A hereto.


 


In order to induce the Company, SPAC Entities,
and Blocker Companies to enter into the Merger Agreement and for other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the Sponsor and each Insider hereby agrees with SPAC Entities and, at all times prior to any valid termination
of the Merger Agreement, the Company as follows:


 


		1.	The Sponsor and each Insider irrevocably
agrees that it, he or she shall:

  

		(a)	vote any ordinary shares owned
by it, him or her (all such ordinary shares, the “Covered Shares”) in favor of the Merger and each other proposal
related to the Merger included on the agenda for the special meeting of stockholders relating to the Merger;

  

		(b)	when such meeting of stockholders
is held, appear at such meeting or otherwise cause the Covered Shares to be counted as present thereat for the purpose of establishing
a quorum;

  

		(c)	vote (or execute and return
an action by written consent), or cause to be voted at such meeting (or validly execute and return and cause such consent to be granted
with respect to), all of such Covered Shares against any Business Combination Proposal and any other action, in each case, that would
reasonably be expected to impede, interfere with, delay, postpone or adversely affect the Merger or any of the other transactions contemplated
by the Merger Agreement, result in a breach of any covenant, representation or warranty or other obligation or agreement of the SPAC
Entities under the Merger Agreement, result in any of the conditions set forth in Article X of the Merger Agreement not being fulfilled,
result in a breach of any covenant, representation or warranty or other obligation or agreement of the Sponsor or the Insiders contained
in this Sponsor Agreement or change in any manner the dividend policy or capitalization of, including the voting rights of, any class
of capital stock of SPAC;

  



     


     


    

 

		(d)	vote (or execute and return
an action by written consent), or cause to be voted at such meeting (or validly execute and return and cause such consent to be granted
with respect to), all of such Covered Shares against any change in business, management or board of directors of SPAC (other than in
connection with the Merger and the other proposals related to the Merger);

  

		(e)	not redeem any Covered Shares owned by it, him or her in
connection with such stockholder approval; and

  





		(f)	execute and return an action
by written resolution approving the board of directors of Acquiror at Closing in accordance with the terms of the Merger Agreement.



 


Prior to any valid termination of the
Merger Agreement, the Sponsor and each Insider shall take, or cause to be taken, all actions and shall do, or cause to be done, all things
reasonably necessary under applicable Laws to consummate the Merger and the other transactions contemplated by the Merger Agreement on
the terms and subject to the conditions set forth therein.


 


The obligations of the Sponsor specified
in this paragraph 1 shall apply whether or not the Merger or any action described above is recommended by the board of directors of SPAC
or whether the board of directors of SPAC has effected a SPAC Change in Recommendation.


 


		2.	The Sponsor and each Insider hereby
agrees and acknowledges that: (a) SPAC and, prior to any valid termination of the Merger Agreement in accordance with its terms, the
Company may be irreparably injured in the event of a breach by the Sponsor or any Insider of its, his or her obligations under paragraphs
1 and 3, as applicable, of this Sponsor Agreement (b) monetary damages may not be an adequate remedy for such breach and (c) the non-breaching
party shall be entitled to injunctive relief, in addition to any other remedy that such party may have in law or in equity, in the event
of such breach.

  

		3.	(a)  	The Sponsor and each Insider agrees that it, he or she shall not Transfer any Founder Shares (or any shares
of Class A Common Stock issuable upon conversion thereof) until the earlier of (A) one hundred eighty (180) days after the completion
of the Merger and (B) subsequent to the Merger, the date on which SPAC completes a liquidation, merger, capital stock exchange, reorganization
or other similar transaction that results in all of SPAC’s stockholders having the right to exchange their shares of Class A Common
Stock for cash, securities or other property (the “Founder Shares Lock-up Period”).

  

		(b)	The Sponsor and each Insider
agrees that it, he or she shall not Transfer any Acquiror Private Placement Warrants (or any Class A ordinary shares issued or issuable
upon the exercise of the Acquiror Private Placement Warrants), until the earlier of (A) one hundred eighty (180) days after the completion
of the Merger and (B) subsequent to the Merger, the date on which SPAC completes a liquidation, merger, capital stock exchange, reorganization
or other similar transaction that results in all of SPAC’s stockholders having the right to exchange their shares of Class A Common
Stock for cash, securities or other property (the “Private Placement Warrants Lock-up Period”
and, together with the Founder Shares Lock-up Period, the “Lock-up Periods”).

  



    2


     


    

 

		(c)	Notwithstanding the provisions
set forth in paragraphs 3(a) and 3(b), Transfers of the Founder Shares, Acquiror Private Placement Warrants and Class A Common Stock
issued or issuable upon the exercise or conversion of the Founder Shares and the Acquiror Private Placement Warrants, in each case, that
are held by the Sponsor, any Insider or any of their permitted transferees (that have complied with this paragraph 3(c)), are permitted
(i) to SPAC’s officers or directors, any affiliate or family member of any of SPAC’s officers or directors or any affiliate
of the Sponsor or to any member(s) of the Sponsor or any of their affiliates; (ii) in the case of an individual, by gift to a member
of such individual’s immediate family or to a trust, the beneficiary of which is a member of such individual’s immediate
family, an affiliate of such individual or to a charitable organization; (iii) in the case of an individual, by virtue of laws of descent
and distribution upon death of such individual; (iv) in the case of an individual, pursuant to a qualified domestic relations order;
(v) by private transfers or transfers made in connection with any contingent forward purchase agreement or similar arrangement or in
connection with the consummation of the Merger at prices no greater than the price at which the shares or warrants were originally purchased;
(vi) in the case of the Sponsor, by virtue of the laws of the State of Delaware or the Sponsor’s limited liability company agreement
upon dissolution of the Sponsor, (vii) in the event of SPAC’s completion of a liquidation, merger, capital stock exchange or other
similar transaction that results in all of SPAC’s stockholders having the right to exchange their Class A Common Stock for cash,
securities or other property subsequent to the completion of the Merger; provided, however, that in the case
of clauses (i) through (vi), these permitted transferees must enter into a written agreement with SPAC agreeing to be bound by the transfer
restrictions herein and the other restrictions contained in this Sponsor Agreement (including, but not limited to, the provisions herein
relating to voting, the Trust Account and liquidating distributions).

  

		(d)	Notwithstanding anything to
the contrary in paragraphs 3(a), 3(b) and 3(c) if either (i) any waiver, release, termination, shortening or other amendment or modification
to the Lockup Agreement, dated as of the date hereof among SPAC and certain stockholders of the Company (the “Lockup Agreement”)
occurs which improves the terms of the lock-up of any shares of Common Stock held by such stockholders immediately following the Closing,
or (ii) the Company waives, releases, terminates, shortens, or otherwise amends or modifies the restrictions in the Lockup Agreement
as to any such Company stockholder (each of the events in (i) or (ii), a “Release”), then the Release shall
apply pro rata and on the same terms to the lock-up on the Founder Shares and the provisions of this Section 3 shall be deemed immediately
and automatically waived, released, terminated, shortened, amended or modified, as the case may be, without further action of the parties.
For the avoidance of doubt, the provisions of this Section 3 shall not be deemed waived, released, terminated, shortened, amended or
modified if any such waiver, release, termination, shortening, amendment or modification would further obligate or is otherwise adverse
to the holders of Founder Shares; provided, however, that in any such circumstances the holders of Founder Shares shall be granted equal
opportunity to participate in such Release on equal terms to the parties thereto prior to the effectiveness thereof. Prior to any such
amendment to the Lockup Agreement and this Agreement, the Company will provide reasonable advance written notice (in no case less than
five (5) Trading Days) to any holder of Founder Shares indicating that the Company plans to take a specified action with respect to the
Lockup Agreement and this Agreement and setting forth the terms of any such amendment.

  

		4.	The Sponsor hereby irrevocably and
unconditionally (i) agrees that pursuant to Article 37 of the SPAC’s Amended & Restated Memorandum of Association (the “Articles”),
all of the Founder Shares outstanding as of the date hereof (whether or not held by the Sponsor), shall convert into shares of Class
A Common Stock on a one-for-one basis and (ii) waives any adjustment to the Conversion Ratio (as defined in the Articles) to which it
would otherwise be entitled pursuant to Article 37.4 of the Articles that would result from the issuance of any equity or equity-linked
securities pursuant to the Subscription Agreements, the Merger or otherwise in connection with the Closing.

  

		5.	The Sponsor and each Insider has
full right and power, without violating any agreement to which it is bound (including, without limitation, any non-competition or non-solicitation
agreement with any employer or former employer), to enter into this Sponsor Agreement.

  



    3


     


    

 

		6.	As used herein: (i) “Beneficially Own”

shares of Class B ordinary shares and the Class A ordinary shares issuable upon conversion of such shares of Class B ordinary shares

to sell, hypothecate, pledge, grant of any option to purchase or otherwise dispose of or agreement to dispose of, directly or indirectly,
or establishment or increase of a put equivalent position or liquidation with respect to or decrease of a call equivalent position within
the meaning of Section 16 of the Exchange Act, and the rules and regulations promulgated thereunder, with respect to, any security, (b)
entry into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership
of any security, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (c) public announcement
of any intention to effect any transaction specified in clause (a) or (b); (iv) “Class A ordinary shares” shall
mean the Class A ordinary shares, par value $0.0001 per share, of SPAC; (v) “Class B ordinary shares” shall
mean the Class B ordinary shares, par value $0.0001 per share, of SPAC; (vi) “ordinary shares” shall mean the

placement that occurred simultaneously with the consummation of SPAC’s initial public offering, pursuant to which the Sponsor is
entitled to purchase up to 12,623,125 Class A ordinary shares; and (viii) “Business Combination Proposal” means
any action to initiate, solicit, facilitate, consider, engage in or continue any discussions or negotiations with, or enter into any
agreement, letter of intent, memorandum of understanding or agreement in principle with, or encourage, response, provide information
to, or commence due diligence with respect to, any Person (other than the Company, its stockholders or any of their Affiliates or Representatives),
concerning, relating to or which is intended or is reasonably likely to give rise to or result in, any offer, inquiry, proposal or indication
of interest, written or oral relating to any merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar
business combination, involving the Company and one or more businesses.




 


		7.	This Sponsor Agreement and the other
agreements referenced herein constitute the entire agreement and understanding of the parties hereto in respect of the subject matter
hereof and supersede all prior understandings, agreements, or representations by or among the parties hereto, written or oral, to the
extent they relate in any way to the subject matter hereof or the transactions contemplated hereby, including, without limitation, with
respect to the Sponsor, each Insider and the Prior Letter Agreement. This Sponsor Agreement may not be changed, amended, modified or
waived (other than to correct a typographical error) as to any particular provision, except by a written instrument executed by SPAC
Entities and the other parties charged with such change, amendment, modification or waiver, it being acknowledged and agreed that the
Company’s execution of such an instrument will not be required after any valid termination of the Merger Agreement in accordance
with its terms.

  

		8.	No party hereto may, except as set
forth herein, assign either this Sponsor Agreement or any of its rights, interests or obligations hereunder, other than in conjunction
with transfers permitted by paragraph 3, without the prior written consent of the other parties (except that, following any valid termination

and assigns and permitted transferees.

stipulations, promises and agreements contained in this Sponsor Agreement shall be for the sole and exclusive benefit of the parties
hereto and their successors, heirs, personal representatives and assigns and permitted transferees.

  

		10.	This Sponsor Agreement may be executed
in any number of original, electronic or facsimile counterparts and each of such counterparts shall for all purposes be deemed to be
an original, and all such counterparts shall together constitute but one and the same instrument.

  

		11.	This Sponsor Agreement shall be
deemed severable, and the invalidity or unenforceability of any term or provision hereof shall not affect the validity or enforceability
of this Sponsor Agreement or of any other term or provision hereof. Furthermore, in lieu of any such invalid or unenforceable term or
provision, the parties hereto intend that there shall be added as a part of this Sponsor Agreement a provision as similar in terms to
such invalid or unenforceable provision as may be possible and be valid and enforceable.

other than the State of Delaware. Any action based upon, arising out of or related to this Sponsor Agreement or the transactions contemplated
hereby may be brought in federal and state courts located in Chancery Court of the State of Delaware, and 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 Borough of Manhattan, State of New York,
New York County), for the purposes of any Proceeding, claim, demand, action or cause of action arising under this Sponsor Agreement,
and further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such Proceeding has been
brought in an inconvenient forum, agrees that all claims in respect of the Proceeding shall be heard and determined only in any such
court, and agrees not to bring any Proceeding arising out of or relating to this Sponsor 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 Proceeding brought pursuant to this paragraph. The prevailing party in any such Proceeding (as determined by
a court of competent jurisdiction) shall be entitled to be reimbursed by the non-prevailing party for its reasonable expenses, including
reasonable attorneys’ fees, incurred with respect to such Action. THE PARTIES EACH HEREBY IRREVOCABLY WAIVE, TO THE FULLEST EXTENT
PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY OF ANY PROCEEDING, CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION ARISING UNDER THIS SPONSOR
AGREEMENT OR IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES IN RESPECT OF THIS SPONSOR AGREEMENT OR
ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY, IN EACH CASE, WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT,
EQUITY, OR OTHERWISE. THE PARTIES EACH HEREBY AGREE AND CONSENT THAT ANY SUCH PROCEEDING, CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL

ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY. EACH PARTY CERTIFIES

OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (B) EACH SUCH PARTY UNDERSTANDS AND HAS CONSIDERED
THE IMPLICATIONS OF THIS WAIVER, (C) EACH SUCH PARTY MAKES THIS WAIVER VOLUNTARILY AND (D) EACH SUCH PARTY HAS BEEN INDUCED TO ENTER

		13.	Any notice, consent or request to
be given in connection with any of the terms or provisions of this Sponsor Agreement shall be in writing and shall be sent by express
mail or similar private courier service, by certified mail (return receipt requested), by hand delivery or electronic or facsimile transmission

		14.	This Sponsor Agreement shall automatically

Merger. In the event of a valid termination of the Merger Agreement in accordance with its terms, this Sponsor Agreement shall be of
no force and effect and shall revert to the Prior Letter Agreement. No such termination or reversion shall relieve the Sponsor, each
Insider, SPAC or the Company from any liability resulting from a breach of this Sponsor Agreement occurring prior to such termination
or reversion.
