(C) Spectaire Holdings Inc., a Delaware corporation with its principal place of business at 155 Arlington Street, Watertown, Massachusetts, 02472, USA (“Spectaire”).

The JVC, Spectaire, and MLab are collectively referred to herein as the “Parties” and individually as a “Party”; Spectaire and MLab are collectively referred to herein as the “JV Parties” and individually as a “JV Party”.

BACKGROUND

(A) The JVC is a newly formed company with issued share capital of Fifty Thousand Euros (EUR 50,000.00) wholly owned by MLab. The share capital has been paid-in in full in cash.

(B) MLab and Spectaire intent to establish and operate a joint venture in the form of the JVC and they shall exercise their rights in relation to the JVC in accordance with the terms and conditions of this Agreement.

(C) The JVC shall carry on business in accordance with the terms and conditions of this Agreement.

Now, therefore, the Parties herewith agree as follows:

SECTION 1. BUSINESS OF THE JVC

1.1 The business of the JVC is the marketing, sale, and manufacture of Spectaire’s proprietary air composition analysis technology “AirCore” (encompassing, in particular, all hardware and software components) (“AirCore Technology”) for the logistics, transport, and warehousing sectors in Europe, the Middle East, and South America including carbon credits activities (the “Business”)

1.2 Each Party shall use its reasonable endeavours to promote and develop the Business to the best advantage of the JVC.

SECTION 2. PERIOD TO CLOSING

The Parties shall procure that prior to Closing, the JVC shall not carry on any trade or business or be engaged in any activities of any sort except as set-forth in this Agreement.

SECTION 3. CLOSING

3.1 The consummation of this Agreement (“Closing”) shall take place on the Scheduled Closing Date at the offices of Mosolf SE & Co. KG in Kirchheim/Tech, Germany, at 9:00 a.m. CET or at another place and/or time agreed upon by the Parties at least in text form.

3.2 The “Scheduled Closing Date” shall be the 10th business day (in Munich, Germany; excluding Saturdays) following the day on which, for the first time, all Closing Conditions have been fulfilled or duly waived or such other day (that succeeds the day of fulfilment / due waiver of the Closing Conditions) agreed upon by the Parties at least in text form. The “Closing Date” is the day on which the Closing actually occurs.

3.3 MLab shall be obligated to consummate this Agreement only if the following condition (“Closing Condition”) has either been fulfilled or waived in writing by MLab:

The JVC has retained Magility GmbH (or, in case Magility GmbH is not available, a comparable provider selected by the JVC) (“Expert”) to perform an expert functional test of the AirCore system in accordance with requirements to be determined by the JVC in good faith and the Expert has, on this basis, determined in writing that Spectaire’s AirCore system functions in all material respects in accordance with the requirements and that the proof of concept is, hence, provided.

The Parties are obligated to work towards the immediate fulfilment of the Closing Condition and to cooperate to this end. The Parties shall inform each other of the current status of the intended fulfilment of the Closing Condition (including the fulfilment itself) and of any circumstances that may prevent or delay the fulfilment of the Closing Condition.

3.4 The Parties acknowledge that, once the proof of concept is provided (cf. Section 3.3), the AirCore system still requires additional development (both relating to hard- and software) so that it can be used in the field, i.e. for trucks under real live conditions. This development of the AirCore system to an “automotive-ready” AirCore system shall be made in due course by Spectaire, shall be funded by Spectaire, and shall be Spectaire’s intellectual property. The “automotive-ready” AirCore units shall be the licensed products under the License Agreement (as defined below). Any required ancillary developments - such as the equipment to attach the “automotive-ready” AirCore units to specific types of trucks or sensors that are introduced into the exhaust tract - may be made by MLab and/or MOSOLF SE & CO. KG or any of its current or future affiliates within the meaning of sections 15 German Stock Corporation Act (AktG) (“Affiliates”). Any intellectual property, including patents, designs, and innovations, embodied in the ancillary developments made by MLab and/or MOSOLF SE & CO. KG or any of its Affiliates shall be jointly owned by MLab and/or MOSOLF SE & CO. KG or any of its Affiliates, as applicable, and Spectaire; the parties shall subsequently enter a separate agreement governing the management, use, registration, protection, and enforcement of such jointly owned intellectual property.

3.5 At the Scheduled Closing Date, the Parties shall take the following actions (“Closing Ac- tions”) in the following order (unless and to the waived by MLab in writing):

(a) Execute the share purchase and assignment agreement attached hereto as Schedule 3.5(a) by which Spectaire purchases and acquires from MLab the 13,000 shares in the JVC with the serial numbers 37,001 through 50,000 in the current shareholder list of the JVC and a nominal value of EUR 1.00 each (the “Spectaire Shares”; the remaining shares in the JVC the “MLab Shares”) against payment of a total purchase price of EUR 13,000.00;

(b) Execute the license agreement attached hereto as Schedule 3.5(b) (the “License Agreement”);

(c) Execute any further ancillary agreements mutually determined and agreed by the Parties, as necessary to carry out the business of the JVC;

(e) Adopt the rules of procedure for the management of the JVC as attached hereto as Schedule 3.5(e) (as amended or superseded from time to time the “RoP”);

(f) Agree - based on a delivery plan to be provided by Spectaire prior to closing and agreed to by MLab - on the Business Plan (as defined in Section 8) for the financial year in which Closing occurs.

3.6 The JV Parties hereby waive, and hereby agree to procure the waiver of, any rights or restrictions which may exist in the Articles or otherwise and which may prevent the transfer of the shares in the JVC pursuant to this Section 3.

3.7 MLab on the one hand and Spectaire on the other hand shall each be entitled to rescind (zurucktreten) this Agreement if the Closing Condition has not been fulfilled or duly waived within six months after the date of notarization of this Agreement (“Signing Date”) or the Closing Actions have not been completely performed or duly waived within two weeks after the Scheduled Closing Date. There is no right of rescission if the rescinding Party is responsible for the occurrence of the reason for rescission or Closing has occurred before receipt of the rescission notice. The rescission shall be effected by written notice by MLab to Spectaire or by Spectaire to MLab, as the case may be. In the event of an effective rescission, (i) all obligations between all Parties pursuant to this Agreement shall cease (this Section 3.7 and Section 13.6 shall remain unaffected) and (ii) any performance already rendered and measures already taken in connection with this Agreement shall be reversed (incl. the First Tranche).

3.8 If Spectaire or any of its current or future Affiliates generates any additional or follow-up business with customers of the JVC (to the extent this is admissible under the License Agreement), for instance by carbon trade activities, the JVC shall receive a fair share in the proceeds to be negotiated between the Parties in good faith.

4.1 In consideration for the rights granted by Spectaire to the JVC, the JVC shall pay to Spectaire a total sum of One Million Five Hundred Thousand United States Dollars ($1,500,000.00 gross) (“Total JVC Payment”).

4

5.2 Each JV Party warrants and represents (garantiert) pursuant to section 311 (1) German Commercial Code (BGB) to the other JV Party that (it being understood that lit. (f) is given by Spectaire to MLab and not by MLab to Spectaire), the following statements are correct at the Signing Date and at the Closing Date:

(a) It is a corporation duly organised and validly existing under the laws of the jurisdiction of its organisation or incorporation;

(b) It has full power and authority and has obtained all necessary authorities and consents to enter into and perform its obligations under this Agreement and such other agreements and arrangements referred to in this Agreement;

(c) The signing of this Agreement and the performance of its obligations under this Agreement and the other agreements and arrangements referred to in this Agreement will not result in a breach of any other agreement or arrangement to which it is a party or any law, nor give rise to any right of termination of any other agreement or arrangement to which it is a party;

(d) There is no action of any nature pending or, to the respective JV Party’s knowledge, threatened against or by the respective JV Party that challenges or seeks to prevent, enjoin, or otherwise delay the transactions contemplated by this Agreement. To the respective JV Party’s knowledge, no event has occurred, or circumstances exist that could reasonably be expected to give rise to, or serve as a basis for, any such action;

(e) No insolvency proceedings or similar proceedings have been, or have been threat- ened to be, initiated against the respective JV Party with respect to the assets of the respective JV Party, nor are there any circumstances that would justify the application for or initiation of such proceedings. In particular, the respective JV Party is neither insolvent, impending insolvent nor overindebted; and

(f) Spectaire is the owner of all patents, trademarks, designs, utility models, domains, copyrights and other registered and unregistered intellectual property rights including application procedures relating thereto (including, in particular, the Know How, Licensed Patents, and Licensed Products as defined in the License Agreement) (collectively the “Intellectual Property Rights”) required for the AirCore system, to duly consummate the License Agreement, and to carry on the envisaged business of the JVC without infringement of any third party rights. The Intellectual Property Rights are effective, enforceable, and unencumbered, and all payments required for the maintenance, care, protection, and enforcement of the Intellectual Property Rights have been made and all necessary steps in this regard have been taken. To Spectaire’s knowledge, no third party has violated the Intellectual Property Rights.

5

5.3 The JV Parties agree that the representations and warranties (Garantien) contained in Section 5.l and Section 5.2 are not granted, and shall not be qualified or construed, as subjective requirements (subjektive Anforderungen), in particular not as guarantee agreements on quality (Beschaffenheitsvereinbarungen) within the meaning of Section 434 (l) German Civil Code (BGB) or as guarantees for the quality of the object of the purchase (Garantien für die Beschaffenheit der Sache) within the meaning of Sections 443, 444 German Civil Code (BGB) but shall qualify as a liability regime sui generis. Sections 442 BGB and 377 German Commercial Code (HGB) shall not apply.

SECTION 6. SHARE TRANSFERS

6.1 No JV Party shall transfer, create any encumbrance over, or otherwise dispose of, or give any person any rights in or over any share or interest in any share in the JVC unless it is permitted under this Agreement and carried out in accordance with the terms of this Agreement. Notwithstanding the foregoing, a JV Party may do anything prohibited by this clause if the other JV Party has consented to it in writing.

6.2 A JV Party may at any time transfer all (but not some only) of its shares in the JVC to a wholly owned subsidiary of that JV Party, any company of which that JV Party is a subsidiary (its holding company), and any other subsidiaries of any such holding company (a “Permitted Transferee” and when carried out, a “Permitted Transfer”).

6.3 A Permitted Transferee holding shares in the JVC as a result of a Permitted Transfer may at any time transfer all (but not some only) of its shares back to the JV Party from whom it received those shares or to another Permitted Transferee of such JV Party.

If the Permitted Transferee fails to make a transfer in accordance with this Section 6, the JVC may based on a shareholders’ resolution (it being understood that the voting rights of the shareholder concerned are excluded) redeem the respective shares against payment of the book value of the respective shares.

SECTION 7. SPECTAIRE CALL RIGHT

7.1 At any time on or after the fifth (5^th) anniversary of the Signing Date (the “Call Commencement Date”), Spectaire shall have the right (the “Call Right”), but not the obligation, to cause MLab to sell all of the MLab Shares to Spectaire at the Call Purchase Price (as defined in Section 7.3).

6

7.2 The Call Right shall be governed by the following procedures:

(a) If Spectaire desires to exercise the Call Right, Spectaire shall deliver to MLab a written notice (the “Call Exercise Notice”) exercising the Call Right.

(b) MLab shall, at the closing of any purchase consummated under this Section 7, represent and warrant (garantieren) pursuant to section 311 (1) German Commercial Code (BGB) to Spectaire that: (i) MLab has full right, title, and interest in and to the MLab Shares; (ii) MLab has all the necessary corporate power and authority and has taken all necessary action to sell such MLab Shares as contemplated by this Section 7; and (iii) the MLab Shares are free and clear of any and all adverse claims, mortgages, pledges, security interests, options, rights of first offer, rights of first refusal, encumbrances, or other restrictions or limitations of any nature whatsoever.

(c) The signing and closing of any sale and assignment of MLab Shares under this Section 7 shall take place no later than sixty (60) days following receipt by MLab of the Call Exercise Notice and shall be implemented by notarized share purchase and assignment agreement. Spectaire shall give MLab at least ten (10) days written notice of the date of notarization (the “Call Right Closing Date”). Spectaire shall pay the Call Purchase Price for the MLab Shares by certified cheque, bank draft, or wire transfer on the Call Right Closing Date. The MLab Shares shall transfer to Spectaire upon receipt by MLab of the entire Call Purchase Price.

(d) On the Call Right Closing Date: (i) MLab shall deliver to the JVC the resignations of any MLab Directors, in each case acknowledging that they have no claims against the JVC, to take effect at completion of the Call Right Closing Date; and (ii) the JV Parties shall take a release resolution (Entlastungsbeschluss) in relation to the MLab Directors covering the period up until the Call Right Closing Date.

(e) The JV Parties shall take all actions as may be reasonably necessary to consummate the sale and assignment contemplated by this Section 7, including, without limitation, entering into agreements and delivering certificates, instruments, resolutions, and consents as may be deemed necessary or appropriate.

7.3 If Spectaire exercises the Call Right hereunder, the purchase price per share at which MLab shall be required to sell the MLab Shares (the “Call Purchase Price”) shall be calculated as of the date of the Call Exercise Notice, as follows:

(a) The Call Purchase Price for the MLab Shares shall be determined by a multiple- evaluation method, calculated as five (5) times the JVC’s earnings before interest, taxes, depreciation, and amortization (EBITDA) (Equity Value).

(b) EBITDA shall be calculated based on the average of JVC’s earnings in the twelve (12) month period immediately preceding the Exercise Notice, compounded annually, according to the JVC’s audited financial records.

7

(c) Notwithstanding the foregoing, the minimum valuation of the JVC for the purpose of Call Purchase Price shall be Five Hundred Thousand United States Dollars (USD $500,000.00) (Equity Value).

(d) If the JV Parties do not agree in writing on the final amount of the Call Purchase Price within thirty (30) days as of receipt of the Call Right Closing Date by MLab, the JV Parties may jointly engage an internationally recognized independent accounting firm (“Expert”) to determine the Call Purchase Price with binding effect for the JV Parties. If the JV Parties cannot agree on an expert within fourteen (14) days as of a respective written request by either JV Party to the other or if the joint appointment is not made within ten days as of such request, the expert shall, upon written request of either JV Party, be appointed by the Institut der Wirtschaftspriifer in Deutschland e.V., Diisseldorf, Germany. The Expert shall act as an arbitrator within the meaning of Sections 317 et seq. German Civil Code (BGB) and shall decide at its reasonable discretion in accordance with section 319 (1) German Civil Code (BGB). The Expert shall also decide on the allocation of the incurred costs and expenses at its reasonable discretion, taking into account section 91 of the German Code of Civil Procedure (ZPO).
