WHEREAS,
concurrently with the execution of this Amendment, the Company, SPAC, Issuer, Artisan LLC (the “Sponsor”),
and the independent directors of SPAC are entering into a Sponsor Forfeiture and Conversion Agreement, pursuant to which, among other
things, and subject to the terms and conditions set forth therein, (i) the Sponsor and the independent directors of SPAC have agreed

2.             Amendment
to the Subscription Agreement. Effective as of the execution hereof:

 

(a)            The
last two sentences in the first paragraph of the Subscription Agreement shall be amended and restated in its entirety to read as follows:

 

“The aggregate number

by (y) the Class A Exchange Ratio (as defined in the Transaction Agreement). The aggregate purchase price to be paid by the

3.            Additional
Agreements.

 

(a)            The
parties hereto hereby confirm that the FPS Purchase Price shall remain unchanged notwithstanding the change to the number of PubCo Forward
Purchase Shares pursuant to this Amendment Deed.

 

(b)            The
Purchaser hereby agrees that, immediately prior to the Initial Closing (as defined in the Amended BCA) (but subject to the satisfaction
or waiver of the conditions precedent to the Initial Closing set forth in Sections 9.1, 9.2 and 9.3 of the Amended BCA), the Purchaser
shall contribute, transfer, assign, convey, and deliver to the Company, and the Company shall acquire and accept from the Purchaser, all
of the Purchaser’s right, title, and interest in, to and under 375,000 Class B Shares and, in exchange therefore, the Company
shall issue to the Purchaser 375,000 Class A Shares (such conversion of Class B Shares into Class A Shares, the “Founder
Share Conversion”).

 

(c)            The
Company and the Purchaser acknowledge and agree that, (i) by effecting the Founder Share Conversion, the Purchaser shall be deemed
to have elected to exercise its option to convert all Class B Shares into Class A Shares pursuant to Article 18.1(a) of
the Charter immediately prior to the Initial Closing; and (ii) for the purposes of Cayman Islands law and pursuant to the Charter,
the Founder Share Conversion shall take effect as a compulsory redemption without notice of all Founder Shares and, on behalf of the Purchaser,
automatic application of such redemption proceeds in paying for the new Class A Shares into which the Class B Shares have been
converted or exchanged at a price per Class B Share necessary to give effect to a conversion or exchange calculated on the basis
that the Class A Shares to be issued as part of the conversion or exchange will be issued at par.

 

(d)            No
share or similar certificates will be issued in connection with the Founder Share Conversion, and the Company will record the conversion
of 375,000 Class B Shares into 375,000 Class A Shares on its books and records. Following the Founder Share Conversion, all
Class B Shares held by the Purchaser shall be cancelled and cease to be outstanding.

 

(e)            The
Founder Share Conversion (i) shall be applicable only in connection with the Initial Merger and this Amendment Deed, and (ii) shall
be void and of no force and effect in the event this Amendment Deed is terminated prior to the Initial Closing.

 

(f)            Notwithstanding
the foregoing of this Section 3, if (i) after completion of the Founder Share Conversion, the Initial Closing does not
occur and the Amended BCA is terminated, or (ii) after completion of the Initial Closing, the Acquisition Closing (as defined in
the Amended BCA) does not occur and the Amended BCA is terminated, each of the Company, the Sponsor and the Purchaser shall take all such
actions that are necessary, proper or advisable under applicable laws such that the Purchaser shall, to the fullest extent possible, be
returned to the position in which the Purchaser would have been, and would be entitled to all rights and benefits that the Purchaser would
have had, if the Founder Share Conversion had not occurred.

 

(g)            The
parties hereto intend that the Founder Share Conversion will be treated as a tax-free recapitalization under Section 368(a)(1)(E) of
the Internal Revenue Code of 1986, as amended.

 

    	 	3	 

     

    

 

4.            No
Further Amendment. The parties hereto agree that except as provided in this Amendment Deed, each of the Amended Forward Purchase Agreement
and the Novation Agreement shall continue in full force and effect, and this Amendment Deed forms an integral and inseparable part of
the Novation Agreement.

 

5.            Termination.
This Amendment Deed shall be automatically terminated with immediate effect without further action by any party hereto upon termination
of the Novation Agreement.

 

6.            References.
All references to the “Business Combination Agreement” in the Amended Forward Purchase Agreement shall mean the Amended BCA.

 

7.            Miscellaneous
Terms. The provisions of Section 10 (General Provisions) of the Amended Forward Purchase Agreement (other than Section 10(b) (Finder’s
Fees)) shall apply to this Amendment Deed, mutatis mutandis, as if set forth in full herein.
