Exhibit 10.11


 


FORM OF FORWARD PURCHASE AGREEMENT


 


This Forward Purchase Agreement (this “Agreement”)
is entered into as of March [•], 2021, by and between GP-Act III Acquisition Corp., a Cayman Islands exempted company (the
 “Company”) and GPIAC II, LLC, a Cayman Islands limited liability company (the “GP Sponsor”).


 


WHEREAS, the Company was incorporated
for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination
with one or more businesses (a “Business Combination”);


 


WHEREAS, the Company has filed with
the U.S. Securities and Exchange Commission (the “SEC”) a registration statement on Form S-1 (as amended, the
 “Registration Statement”) for its initial public offering (“IPO”) of units (the “Public
Units”) at a price of $10.00 per Public Unit, each comprised of one Class A ordinary share of the Company, par
value $0.0001 per share (the “Class A Shares”), and one-third of one redeemable warrant, where each whole
redeemable warrant is exercisable to purchase one Class A Share at an exercise price of $11.50 per share (the “Warrants”).
Only whole Warrants are exercisable. A holder of Warrants will not be able to exercise any fraction of a Warrant. The Company
shall not issue fractional Warrants other than as part of the Public Units. If, upon the detachment of the Warrants from the Public
Units or otherwise, a holder of Warrants would be entitled to receive a fractional Warrant, the Company shall round down to the
nearest whole number the number of Warrants to be issued to such holder;


 


WHEREAS, following the closing of
the IPO (the “IPO Closing”), the Company will seek to identify and consummate a Business Combination; and


 


WHEREAS, the parties wish to enter
into this Agreement, pursuant to which immediately prior to the closing of the Company’s initial Business Combination (the
 “Business Combination Closing”), the Company shall issue and sell, and the Purchaser (as defined below) shall
purchase, on a private placement basis, $50.0 million of units (the “Forward Purchase Units”), consisting of
5,000,000 Class A Shares (the “Forward Purchase Shares”) and 1,666,667 Warrants (the “Forward
Purchase Warrants” and together with the Forward Purchase Shares, the “Forward Purchase Securities”)
on the terms and conditions set forth herein;


 


NOW, THEREFORE, in consideration
of the premises, representations, warranties and the mutual covenants contained in this Agreement, and for other good and valuable
consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the parties hereto agree as follows:



     


     


    


		1.	Sale
                                         and Purchase.



 


		(a)	Designation
                                         of Purchaser.



 


(i)          The
GP Sponsor agrees to purchase the Forward Purchase Units on the terms set forth in this Agreement or, if the Purchaser is the
Designated Purchaser (each as defined below), the GP Sponsor agrees to procure that the Designated Purchaser shall comply with
its obligations under this Agreement as the Purchaser.


 


(ii)         The
purchaser (the “Purchaser”) of the Forward Purchase Units shall be either (a) the GP Sponsor, or (b) a
subsidiary or affiliate of GP Investments, Ltd., an exempted company limited by shares incorporated and organized under the
laws of Bermuda (as determined by the GP Sponsor) (the “Designated Purchaser”) that executes a joinder
agreement substantially in the form set forth on Exhibit B hereto (the “Joinder
Agreement”).


 


(iii)       
In the event that the GP Sponsor designates the Designated Purchaser to be the purchaser of the Forward Purchase Units,
upon the execution of the Joinder Agreement, the Designated Purchaser shall thereby become a party to this Agreement and shall
be bound by the terms of the Agreement as if the Designated Purchaser were an original signatory to this Agreement. Upon the execution
of the Joinder Agreement, all references in this Agreement to the “Purchaser” shall be deemed to be references to
the Designated Purchaser.


 


		(b)	Forward
                                         Purchase Securities.



 


(i)         
The Company shall issue and sell to the Purchaser, and the Purchaser shall purchase from the Company, the Forward Purchase
Shares and the Forward Purchase Warrants for an aggregate purchase price of $50.0 million (the “FPS
Purchase Price”).


 


(ii)        
Each Forward Purchase Warrant will have the same terms as each Warrant sold as part of the Public Units in the IPO (“Public
Warrants”), and will be subject to the terms and conditions of the Warrant Agreement to be entered into between
the Company and Continental Stock Transfer & Trust Company, as Warrant Agent, in connection with the IPO (the “Warrant
Agreement”). Each Forward Purchase Warrant will entitle the holder thereof to purchase one Class A Share
at a price of $11.50 per share, subject to adjustment as described in the Warrant Agreement, and only whole Forward Purchase Warrants
will be exercisable. The Forward Purchase Warrants will become exercisable on the later of 30 days after the Business Combination
Closing and 12 months from the closing of the IPO, and will expire five years after the Business Combination Closing or earlier
upon redemption or the liquidation of the Company, as described in the Warrant Agreement.



    2


     


    


(iii)       
The Company shall require the Purchaser to purchase the Forward Purchase Securities by delivering notice to the Purchaser,
at least five (5) Business Days before the Business Combination Closing, specifying the date of the Business Combination
Closing and instructions for wiring the FPS Purchase Price. The closing of the sale of the Forward Purchase Securities (the “FPS
Closing”) shall be held on the same date and immediately prior to the Business Combination Closing (such date
being referred to as the “FPS Closing Date”). At least one (1) Business
Day prior to the FPS Closing Date, the Purchaser shall deliver to the Company, to be held in escrow until the FPS Closing, the
FPS Purchase Price for the Forward Purchase Securities by wire transfer of U.S. dollars in immediately available funds to the
account specified by the Company in such notice. Immediately prior to the FPS Closing on the FPS Closing Date, (A) the FPS
Purchase Price shall be released from escrow automatically and without further action by the Company or the Purchaser, and (B) upon
such release, the Company shall issue the Forward Purchase Securities (individually or collectively, the “Securities”)
to the Purchaser in book-entry form, free and clear of any liens or other restrictions whatsoever (other than those arising under
state or federal securities laws), registered in the name of the Purchaser (or its nominee in accordance with its delivery instructions),
or to a custodian designated by the Purchaser, as applicable. In the event the Business Combination Closing does not occur on
the date scheduled for closing, the FPS Closing shall not occur and the Company shall promptly (but not later than one (1) Business
Day thereafter) return the FPS Purchase Price to the Purchaser. For the purposes of this Agreement, “Business
Day” means any day, other than a Saturday or a Sunday, that is neither a legal holiday nor a day on which banking
institutions are generally authorized or required by law or regulation to close in the City of New York, New York.


 


(c)          
Legend. Each register and book entry for the Securities
shall contain a notation, and each certificate (if any) evidencing the Securities shall be stamped or otherwise imprinted with
a legend, in substantially the following form:


 


“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN
REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION, AND MAY
NOT BE TRANSFERRED IN VIOLATION OF SUCH ACT AND LAWS.”


 


(d)          
Legend Removal. If the Securities are eligible to
be sold without restriction under, and without the Company being in compliance with the current public information requirements
of, Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”),
then at the Purchaser’s request, the Company will, at its sole expense, cause the Company’s transfer agent to remove
the legend set forth in Section 1(b). In connection therewith, if required by the Company’s transfer agent,
the Company will promptly cause an opinion of counsel to be delivered to and maintained with its transfer agent, together with
any other authorizations, certificates and directions required by the transfer agent that authorize and direct the transfer agent
to transfer such Securities without any such legend; provided, however, that the Company will not be required to deliver
any such opinion, authorization or certificate or direction if it reasonably believes that removal of the legend could reasonably
be expected to result in or facilitate transfers of Securities in violation of applicable law.


 


(e)          
Registration Rights. The Purchaser shall have registration
rights with respect to the Forward Purchase Securities as set forth on Exhibit A hereto (the “Registration
Rights”).

authority to enter into this Agreement. This Agreement, when executed and delivered by the Purchaser, will constitute the valid
and legally binding obligation of the Purchaser, enforceable in accordance with its terms, except (a) as limited by applicable
bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and any other laws of general application affecting
enforcement of creditors’ rights generally, (b) as limited by laws relating to the availability of specific performance,
injunctive relief or other equitable remedies, or (c) to the extent the indemnification provisions contained in the Registration
Rights may be limited by applicable federal or state securities laws.


 


(c)          
Governmental Consents and Filings. No consent, approval,
order or authorization of, or registration, qualification, designation, declaration or filing with, any federal, state or local
governmental authority is required on the part of the Purchaser in connection with the consummation of the transactions contemplated
by this Agreement.


 


(d)          
Compliance with Other Instruments. The execution,
delivery and performance by the Purchaser of this Agreement and the consummation by the Purchaser of the transactions contemplated
by this Agreement will not result in any violation or default (i) of any provisions of its organizational documents, (ii) of
any instrument, judgment, order, writ or decree to which it is a party or by which it is bound, (iii) under any note, indenture
or mortgage to which it is a party or by which it is bound, (iv) under any lease, agreement, contract or purchase order to
which it is a party or by which it is bound or (v) of any provision of federal or state statute,

each case (other than clause (i)), which would have a material adverse effect on the Purchaser or its ability to consummate the
transactions contemplated by this Agreement.


 


(e)          
Purchase Entirely for Own Account. This Agreement
is made with the Purchaser in reliance upon the Purchaser’s representation to the Company, which by the Purchaser’s
execution of this Agreement, the Purchaser hereby confirms, that the Forward Purchase Securities to be acquired by the Purchaser
will be acquired for investment for the Purchaser’s own account, not as a nominee or agent, and not with a view to the resale
or distribution of any part thereof, and that the Purchaser has no present intention of selling, granting any participation in,
or otherwise distributing the same in violation of law. By executing this Agreement, the Purchaser further represents that the

participations to such Person or to any third Person, with respect to any of the Forward Purchase Securities. For purposes of

(g)          
Restricted Securities. The Purchaser understands
that the offer and sale of the Forward Purchase Securities to the Purchaser has not been, and will not be, registered under the
Securities Act, by reason of a specific exemption from the registration provisions of the Securities Act which depends upon, among
other things, the bona fide nature of the investment intent and the accuracy of the Purchaser’s representations as expressed
herein. The Purchaser understands that the Forward Purchase Securities are “restricted securities” under applicable
U.S. federal and state securities laws and that, pursuant to these laws, the Purchaser must hold the Forward Purchase Securities
indefinitely unless they are registered with the SEC and qualified by state authorities, or an exemption from such registration
and qualification requirements is available. The Purchaser acknowledges that the Company has no obligation to register or qualify
the Forward Purchase Securities, or any Class A Shares into which the Forward Purchase Securities may be converted into or
exercised for, for resale, except pursuant to the Registration Rights. The Purchaser further acknowledges that if an exemption
from registration or qualification is available, it may be conditioned on various requirements including, but not limited to,
the time and manner of sale, the holding period for the Forward Purchase Securities, and on requirements relating to the Company
which are outside of the Purchaser’s control, and which the Company is under no obligation and may not be able to satisfy.
The Purchaser acknowledges that the Company filed the Registration Statement for its proposed IPO to the SEC. The Purchaser understands
that the offering of the Forward Purchase Securities is not, and is not intended to be, part of the IPO, and that the Purchaser
will not be able to rely on the protection of Section 11 of the Securities Act with respect to such Forward Purchase Securities.


 


(h)          
No Public Market. The Purchaser understands that
no public market now exists for the Securities, and that the Company has made no assurances that a public market will ever exist
for the Securities.


 


(i)           
High Degree of Risk. The Purchaser understands that
its agreement to purchase the Securities involves a high degree of risk which could cause the Purchaser to lose all or part of
its investment.


 


(j)           
Accredited Investor. The Purchaser is an “accredited
investor” as defined in Rule 501(a) of Regulation D promulgated under the Securities Act.


 


(k)          
No General Solicitation. Neither the Purchaser,
nor any of its officers, directors, employees, agents, shareholders or partners has either directly or indirectly, including,
through a broker or finder (i) to its knowledge, engaged in any general solicitation, or (ii) published any advertisement
in connection with the offer and sale of the Forward Purchase Securities.

(the “Underwriters”) or, to its actual knowledge, any other member of the Financial Industry Regulatory Authority
(“FINRA”) that is participating in the IPO.


 


(o)          
No Other Representations and Warranties; Non-Reliance.
Except for the specific representations and warranties contained in this Section 2 and in any certificate or agreement
delivered pursuant hereto, none of the Purchaser nor any person acting on behalf of the Purchaser nor any of the Purchaser’s
affiliates (the “Purchaser Parties”) has made, makes or shall be deemed
to make any other express or implied representation or warranty with respect to the Purchaser and the offering of the Forward
Purchase Securities, and the Purchaser Parties disclaim any such representation or warranty. Except for the specific representations
and warranties expressly made by the Company in Section 3 of this Agreement and in any certificate or agreement delivered
pursuant hereto, the Purchaser Parties specifically disclaim that they are relying upon any other representations or warranties
that may have been made by the Company, any person on behalf of the Company or any of the Company’s affiliates (collectively,

    14


     


    


(j)           
Jurisdiction. The parties (i) hereby irrevocably
and unconditionally submit to the jurisdiction of the state courts of New York and to the jurisdiction of the United States District
Court for the Southern District of New York for the purpose of any suit, action or other proceeding arising out of or based upon
this Agreement, (ii) agree not to commence any suit, action or other proceeding arising out of or based upon this Agreement
except in state courts of New York or the United States District Court for the Southern District of New York, and (iii) hereby
waive, and agree not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim
that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment

or waived as to any particular provision, except with the prior written consent of the Company and the Purchaser.


 


(m)         
Severability. The provisions of this Agreement will
be deemed severable and the invalidity or unenforceability of any provision will not affect the validity or enforceability of
the other provisions hereof; provided, that, if any provision of this Agreement, as applied to any party hereto or to any
circumstance, is adjudged by a governmental authority, arbitrator, or mediator not to be enforceable in accordance with its terms,
the parties hereto agree that the governmental authority, arbitrator, or mediator making such determination will have the power
to modify the provision in a manner consistent with its objectives such that it is enforceable, and/or to delete specific words
or phrases, and in its reduced form, such provision will then be enforceable and will be enforced.


 


(n)          
Expenses. The Company will bear its own and the

issuable upon conversion or exercise of the Forward Purchase Securities.


 


(o)          
Construction. The parties hereto have participated
jointly in the negotiation and drafting of this Agreement. If an ambiguity or question of intent or interpretation arises, this
Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of proof will arise favoring
or disfavoring any party hereto because of the authorship of any provision of this Agreement. Any reference to any federal, state,
local, or foreign law will be deemed also to refer to law as amended and all rules and regulations promulgated thereunder, unless
the context requires otherwise. The words “include,” “includes,” and “including”
will be deemed to be followed by “without limitation.” Pronouns in masculine, feminine, and neuter genders
will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice
versa, unless the context otherwise requires. The words “this Agreement,” “herein,” “hereof,”
 “hereby,” “hereunder,” and words of similar import refer to this Agreement as a whole and
not to any particular subdivision unless expressly so limited. The parties hereto intend that each representation, warranty, and
covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty, or
covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to
the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will not detract
from or mitigate the fact that such party hereto is in breach of the first representation, warranty, or covenant.



    15


     


    


(p)          
Waiver. No waiver by any party hereto of any default,
misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not, may be deemed to extend to any prior
or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights arising
because of any prior or subsequent occurrence.


 


(q)          
Confidentiality. Except as may be required by law,
regulation or applicable stock exchange listing requirements, unless and until the transactions contemplated hereby and the terms
hereof are publicly announced or otherwise publicly disclosed by the Company, the parties hereto shall keep confidential and shall
not publicly disclose the existence or terms of this Agreement.


 


(r)           
Specific Performance. The Purchaser agrees that
irreparable damage may occur in the event any provision of this Agreement was not performed by the Purchaser in accordance with
the terms hereof and that the Company shall be entitled to specific performance of the terms hereof, in addition to any other
remedy at law or equity.

		1.	Within thirty (30) days after the Business Combination Closing,
                                         the Company shall use commercially reasonable efforts (i) to file a registration
                                         statement on Form S-1, to the extent the Company is required to use such form, for a
                                         secondary offering (including any successor registration statement covering the resale
                                         of the Registrable Securities, a “Resale Shelf”) of (x) the Class A
                                         Shares and Warrants (and underlying Class A Shares) comprising the Forward Purchase
                                         Securities, (y) any other Class A Shares that may be acquired by the Purchaser
                                         after the date of this Agreement, including any time after the Business Combination Closing,
                                         and (z) any other equity security of the Company issued or issuable with respect
                                         to the securities referred to in clauses (x) and (y) by way of a share dividend
                                         or share split or in connection with a combination of shares, recapitalization, merger,
                                         consolidation or reorganization (collectively, for so long as such securities are held
                                         by the Purchaser or its assignees under the Agreement, each a “Holder”),
                                         (the “Registrable Securities”) pursuant to Rule 415 under the Securities
                                         Act; provided, that, if Form S-3 is available for such a registration, the Company
                                         shall register the resale of the Registrable Securities on Form S-3 as soon as such form
                                         is available and such Form S-3 shall also be deemed to be a Resale Shelf, (ii) to
                                         cause the Resale Shelf to be declared effective under the Securities Act promptly thereafter,
                                         but in no event later than sixty (60) days after the initial filing of the Resale
                                         Shelf, and (iii) to maintain the effectiveness of such Resale Shelf with respect
                                         to the Purchaser’s Registrable Securities until the earliest of (A) the date
                                         on which the Purchaser or its respective assignees cease to hold Registrable Securities
                                         covered by such Resale Shelf, and (B) the date all of the Purchaser’s Registrable
                                         Securities covered by the Resale Shelf can be sold publicly without restriction or limitation
                                         (including without volume or manner of sale restrictions) under Rule 144 under the Securities
                                         Act.



 


		2.	The Holders may, after the Resale Shelf becomes effective, deliver
                                         a written notice to the Company (the “Underwritten Offering Notice”)
                                         specifying that the sale of some or all of the Registrable Securities subject to the
                                         Resale Shelf is intended to be conducted through a firm commitment underwritten offering
                                         (an “Underwritten Offering”); provided, however,
                                         that the Holders of Registrable Securities may not, without the Company’s prior
                                         written consent, (i) launch an Underwritten Offering the anticipated gross proceeds
                                         of which shall be less than $10,000,000 (unless the Holders are proposing to sell all
                                         of their remaining Registrable Securities), (ii) launch more than three Underwritten
                                         Offerings at the request of the Holders, (iii) launch more than two Underwritten
                                         Offerings within any three-hundred sixty-five (365) day-period or (iv) launch
                                         an Underwritten Offering within the period commencing fourteen (14) days prior to
                                         and ending two (2) days following the Company’s scheduled earnings release
                                         date for any fiscal quarter or year. In the event of an Underwritten Offering, the Holders
                                         representing a majority-in-interest of the Registrable Securities to be included in such
                                         Underwritten Offering shall select the managing underwriter(s) for the Underwritten Offering; provided that
                                         the choice of such managing underwriter(s) shall be subject to the consent of the Company,
                                         which is not to be unreasonably withheld, conditioned or delayed. If the underwriter(s)
                                         for any Underwritten Offering pursuant to this paragraph 2 of this Exhibit A (each, a
                                         “Secondary Offering”) advise the Company and the Holders that, in
                                         their good faith opinion, marketing factors require a limitation on the number of securities
                                         that may be included in such Secondary Offering, the number of securities to be so included
                                         shall be allocated as follows: (i) first, to the Holders that have requested to
                                         participate in such Secondary Offering, allocated pro rata among such
                                         Holders on the basis of the percentage of the Registrable Securities requested to be
                                         included in such Secondary Offering by such Holders, and (ii) second, to the holders
                                         of any other securities of the Company that have been requested to be so included.




    A-1


     


    


		3.	Upon receipt of prior written notice by any Holder that they intend to effect a sale of Registrable Securities held by them
as are then registered pursuant to the Resale Shelf, the Company shall use its reasonable best efforts to cooperate in such sale
(whether or not such sale constitutes an Underwritten Offering), including by amending or supplementing the prospectus related
to such Resale Shelf as may be reasonably requested by such Holder for so long as such Holder holds Registrable Securities.



 


		4.	In the event the Company is prohibited by applicable rule, regulation
                                         or interpretation by the staff (“Staff”) of the Securities and Exchange
                                         Commission (“SEC”) from registering all of the Registrable Securities
                                         on the Resale Shelf or the Staff requires that any Holder be specifically identified
                                         as an “underwriter” in order to permit such registration statement to become
                                         effective, and such Holder does not consent in writing to being so named as an underwriter
                                         in such registration statement, the number of Registrable Securities to be registered
                                         on the Resale Shelf will be reduced on a pro rata basis among all Holders to be so included,
                                         unless otherwise required by the Staff, so that the number of Registrable Securities
                                         to be registered is permitted by the Staff and such Holder is not required to be named
                                         as an “underwriter”; provided, that, any Registrable Securities
                                         not registered due to this paragraph 4 shall thereafter as soon as allowed by the SEC
                                         guidance be registered to the extent the prohibition no longer is applicable.



 


		5.	If at any time the Company proposes to file a registration statement
                                         (a “Registration Statement”) on its own behalf, or on behalf of any
                                         Persons other than the Holders who have registration rights (“Other Holders”),
                                         relating to an Underwritten Offering of ordinary shares (a “Company Offering”),
                                         then the Company will provide the Holders with notice in writing (an “Offer
                                         Notice”) at least five (5) Business Days prior to such filing, which Offer
                                         Notice will offer to include in the Registration Statement the Registrable Securities
                                         held by each Holder. Within three (3) Business Days after receiving the Offer Notice,
                                         each Holder may make a written request to the Company to include some or all of such
                                         Holder’s Registrable Securities in the Registration Statement. If the underwriter(s)
                                         for any Company Offering advise the Company that, in their good faith opinion, marketing
                                         factors require a limitation on the number of securities that may be included in the
                                         Company Offering, the number of securities to be so included shall be allocated as follows:
                                         (i) first, to the Company and the Other Holders, if any; and (ii) second, to
                                         the Holders.



 


		6.	In connection with any Underwritten Offering, the Company shall enter into such customary agreements and take all such other
actions in connection therewith (including those reasonably requested by Holders representing a majority-in-interest of the Registrable
Securities to be included in such Underwritten Offering) in order to facilitate the disposition of such Registrable Securities
as are reasonably necessary or required, and in such connection enter into a customary underwriting agreement that provides for
customary opinions, comfort letters and officer’s certificates and other customary deliverables.

		7.	At any time during which the Company has an effective Resale Shelf
                                         with respect to the Purchaser’s Registrable Securities, the Purchaser may make
                                         a written request (which request shall specify the intended method of disposition thereof)
                                         (a “Shelf Takedown Request”) to the Company to effect a sale, of all
                                         or a portion of the Purchaser’s Registrable Securities that are covered by the
                                         Resale Shelf, and the Company shall use commercially reasonable efforts to file a prospectus
                                         supplement for such purpose as soon as reasonably practicable following receipt of a
                                         Shelf Takedown Request.



 


		8.	The Company shall pay all fees and expenses incident to the performance
                                         of or compliance with its obligation to prepare, file and maintain the Resale Shelf (including
                                         the fees of its counsel and accountants). The Company shall also pay all Registration
                                         Expenses. For purposes of this paragraph 7, “Registration Expenses”
                                         shall mean the out-of-pocket expenses of any Secondary Offering and any Company Offering,
                                         including, without limitation, the following: (i) all registration and filing fees
                                         (including fees with respect to filings required to be made with FINRA) and any securities
                                         exchange on which the Registrable Securities are then listed; (ii) fees and expenses
                                         of compliance with securities or blue sky laws (including reasonable fees and disbursements
                                         of counsel for the underwriters in connection with blue sky qualifications of the Registrable
                                         Securities); (iii) printing, messenger, telephone and delivery expenses; (iv) reasonable
                                         fees and disbursements of counsel for the Company; and (v) reasonable and documented
                                         fees and expenses of one legal counsel selected by Holders representing a majority-in-interest
                                         of the Registrable Securities participating in any such Secondary Offering or Company
                                         Offering, who will represent all the selling shareholders.



 


		9.	The Company may suspend the use of a prospectus included in the
                                         Resale Shelf by furnishing to each Holder a written notice (“Suspension Notice”)
                                         stating that in the good faith judgment of the Company, it would be either (i) prohibited
                                         by the Company’s insider trading policy (as if the Holders were covered by such
                                         policy) or (ii) materially detrimental to the Company and its shareholders for such
                                         prospectus to be used at such time. The Company’s right to suspend the use of such
                                         prospectus under clause (ii) of the preceding sentence may be exercised for a period
                                         of not more than sixty (60) days after the date of such notice to the Holders; provided,
                                         such period may be extended for an additional thirty (30) days with the consent
                                         of a majority-in-interest of the Holders of Registrable Securities covered by the Resale
                                         Shelf, which consent shall not be unreasonably withheld; provided, further, that
                                         such right to suspend the use of a prospectus shall be exercised by the Company not more
                                         than twice in any twelve (12) month period. A Holder of Registrable Securities shall
                                         not effect any sales of Registrable Securities pursuant to the Resale Shelf at any time
                                         after it has received a Suspension Notice from the Company and prior to receipt of an
                                         End of Suspension Notice (as defined below). The Holders may recommence effecting sales
                                         of the Registrable Securities pursuant to the Resale Shelf following further written
                                         notice to such effect (an “End of Suspension Notice”) from the Company
                                         to the Holders. The Company shall act in good faith to permit any suspension period contemplated
                                         by this paragraph 8 to be concluded as promptly as reasonably practicable.




    A-3


     


    


		10.	The Holders agree that, except as required by applicable law, the Purchaser shall treat as confidential the receipt of any
Suspension Notice (provided, that, in no event shall such notice contain any material nonpublic information of the Company)
hereunder and shall not disclose or use the information contained in such Suspension Notice without the prior written consent of
the Company until such time as the information contained therein is or becomes public, other than as a result of disclosure by
a Holder of Registrable Securities in breach of the terms of this Agreement.



 


		11.	The Company shall indemnify and hold harmless the Holders, their
                                         respective directors and officers, partners, members, managers, employees, agents, and
                                         representatives and each person, if any, who controls a Holder within the meaning of
                                         the Securities Act and the Exchange Act and any agent thereof (collectively, “Indemnified
                                         Persons”), to the fullest extent permitted by applicable law, from and against
                                         any losses, claims, damages, liabilities, joint or several, costs (including reasonable
                                         costs of preparation and reasonable attorneys’ fees) and expenses, judgments, fines,
                                         penalties, interest, settlements or other amounts arising from any and all claims, demands,
                                         actions, suits or proceedings, whether civil, criminal, administrative or investigative,
                                         in which any Indemnified Person may be involved, or is threatened to be involved, as
                                         a party or otherwise, under the Securities Act or otherwise (collectively, “Losses”),
                                         promptly as incurred, arising out of, based upon or resulting from any untrue statement
                                         or alleged untrue statement of any material fact contained in the Resale Shelf (or any
                                         amendment or supplement thereto), the related prospectus, or any amendment or supplement
                                         thereto, or arise out of, are based upon or resulting from the omission or alleged omission
                                         to state therein a material fact required to be stated therein or necessary to make the
                                         statements therein, in light of the circumstances in which they were made, not misleading;
                                         provided, however, that the Company shall not be liable in any such case or to
                                         any Indemnified Person to the extent that any such Loss arises out of, is based upon
                                         or results from an untrue statement or alleged untrue statement or omission or alleged
                                         omission or so made in reliance upon or in conformity with information furnished by or
                                         on behalf of such Indemnified Person in writing specifically for use in the preparation
                                         of the Resale Shelf, the related prospectus, or any amendment or supplement thereto.
                                         Such indemnity shall remain in full force and effect regardless of any investigation
                                         made by or on behalf of such Indemnified Person, and shall survive the transfer of such
                                         securities by the Holders.



 


		12.	The Company’s obligation under paragraph (1) of this Exhibit A is subject to each Holder’s furnishing to the
Company in writing such information as the Company reasonably requests for use in connection with the Resale Shelf, the related
prospectus, or any amendment or supplement thereto. Each Holder shall indemnify the Company, its officers, directors, managers,
employees, agents and representatives, and each person who controls the Company (within the meaning of the Securities Act) against
any losses, claims, damages, liabilities and expenses resulting from any untrue statement or alleged untrue statement of material
fact contained in the Resale Shelf, the related prospectus, or any amendment or supplement thereto or any omission or alleged omission
of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent
that such untrue statement or omission is contained in any information so furnished in writing by such Holder expressly for inclusion
in such document; provided, that, the obligation to indemnify shall be individual, not joint and several, with respect to
the Holders and the Other Holders and shall be limited to the net amount of proceeds received by each Holder and each Other Holder
from the sale of Registrable Securities pursuant to the Resale Shelf.




    A-4


     


    


		13.	The Company shall cooperate with the Holders, to the extent the Registrable Securities become freely tradable, to facilitate
the timely preparation and delivery of certificates (not bearing any restrictive legend) representing the Registrable Securities
to be offered pursuant to a Resale Shelf and enable such certificates to be in such denominations or amounts, as the case may be,
as the Holders may reasonably request and registered in such names as each Holder may request.



 


		14.	If requested by the Holders representing a majority in interest of the Registrable Securities, the Company shall as soon as
practicable, subject to any Suspension Notice, (i) incorporate in a prospectus supplement or post-effective amendment such
information as each Holder reasonably requests to be included therein relating to the sale and distribution of Registrable Securities,
including, without limitation, information with respect to the number of Registrable Securities being offered or sold, the purchase
price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering; (ii) make
all required filings of such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated
in such prospectus supplement or post-effective amendment; and (iii) supplement or make amendments to any Registration Statement
if reasonably requested by the Holders representing a majority in interest of the Registrable Securities.



 


		15.	As long as the Registrable Securities are outstanding, the Company, at all times while it shall be reporting under the Exchange
Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports
required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act, and to promptly
furnish the Holders with true and complete copies of all such filings, unless filed through the SEC’s EDGAR system. The Company
further covenants that it shall take such further action as the Holders may reasonably request, all to the extent required from
time to time, to enable the Holders to sell the Class A Shares and Warrants held by the Holders without registration under
the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act, including
providing any legal opinions. Upon the request of any Holder, the Company shall deliver to such Holder a written certification
of a duly authorized officer as to whether it has complied with such requirements.



 


		16.	The rights, duties and obligations of the Purchaser under this Exhibit A may be assigned or delegated by the Purchaser in conjunction
with and to the extent of any permitted transfer or assignment of Registrable Securities by the Purchaser to any permitted transferee
or assignee.
