Ladies and Gentlemen:

This Subscription Agreement (this “Subscription Agreement”) is being entered into as of the date set forth on the signature page hereto, by and among OCA Acquisition Corp., a Delaware corporation (“OCA”) and the undersigned investor (the “Investor”) in connection with the Business Combination Agreement, dated as of the date hereof (as may be amended, supplemented or otherwise modified from time to time, the “Transaction Agreement”), by and among OCA, Powermers Smart Industries, Inc., a Delaware corporation (the “Company”) and POWR Merger Sub, LLC, a Delaware limited liability company and prior to the Closing Date, a wholly owned subsidiary of the Company (“Merger Sub”), pursuant to which, among other things, on the Closing Date, Merger Sub will merge with and into OCA, with OCA being the surviving company of such merger (the “Merger”) and wholly owned subsidiary of the Company, and each issued and outstanding share of OCA Common Stock (as defined below) will be automatically cancelled, extinguished and converted into the right to receive one share of common stock, par value $0.01 per share, of the Company (the “Company Common Stock”), on the terms and subject to the conditions set forth in the Transaction Agreement (the “Transaction”).

In connection therewith, and in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions, set forth herein, and intending to be legally bound hereby, each of the Investor and OCA acknowledges and agrees as follows:

1. Subscription. The Investor hereby irrevocably subscribes for and agrees to purchase from OCA, and OCA agrees to issue and sell to the Investor, 200,000 shares of Class A common stock, par value $0.0001 per share (the “Class A Common Stock”), in a private placement for a purchase price of $2,000,000.00 (the “Subscription Amount”), on the Closing Date, immediately prior to the Merger, subject to the terms and subject to the conditions set forth in this Subscription Agreement.

2. Closing. The closing of the sale, purchase and issuance of shares of Class A Common Stock contemplated hereby (the “Closing”) is contingent upon the substantially concurrent consummation of the Transaction but immediately prior to the Merger. The Closing shall occur substantially concurrently with and be conditioned upon the effectiveness of the Transaction and immediately prior to the Merger (the date the Closing so occurs, the “Closing Date”). Upon delivery of written notice from (or on behalf of) OCA to the Investor (the “Closing Notice”) that OCA reasonably expects all conditions to the closing of the Transaction to be satisfied or waived on a date that is not less than five (5) business days from the date on which the Closing Notice is delivered to the Investor, the Investor shall deliver to OCA, three (3) business days prior to the anticipated Closing Date specified in the Closing Notice, (i) the Subscription Amount by wire transfer of United States dollars in immediately available funds to the account(s) specified by OCA in the Closing Notice (which account shall not be an escrow account) and (ii) any other information that is reasonably requested in the Closing Notice in order for shares of Class A Common Stock to be issued to the Investor, including, without limitation, the legal name of the person in whose name such shares are to be issued and a duly executed Internal Revenue Service Form W-9 or appropriate Form W-8, as applicable. On the Closing Date, OCA shall issue a number of shares of Class A Common Stock to the Investor set forth on the signature page to this Subscription Agreement and subsequently cause such shares of Class A Common Stock to be registered in book entry form, free and clear of all liens (other than those arising under applicable securities laws and as provided for in the Merger Agreement), in the name of the Investor on OCA’s share register; provided, however, that OCA’s obligation to issue shares of Class A Common Stock to the Investor is contingent upon OCA having received the Subscription Amount in full in accordance with this Section 2. In the event the Closing does not occur within two (2) business days of the anticipated Closing Date specified in the Closing Notice, OCA shall promptly (but not later than three (3) business days thereafter) return the Subscription Amount in full to the Investor; provided that, unless this Subscription Agreement has been terminated pursuant to Section 8 hereof, such return of funds shall not terminate this Subscription Agreement or relieve the Investor of its obligation to purchase shares of Class A Common Stock at the Closing upon the delivery by OCA of a subsequent Closing Notice in accordance with this Section 2. For purposes of this Subscription Agreement, “business day” shall mean any day other than a Saturday, Sunday or other day on which commercial banking institutions in New York, New York are authorized or required to close for business.

a. OCA is duly incorporated and validly existing as a corporation in good standing under the laws of the State of Delaware. OCA has all power (corporate or otherwise) and authority to own, lease and operate its properties and conduct its business as presently conducted and to enter into, deliver and perform its obligations under this Subscription Agreement.

b. As of the Closing Date, shares of Class A Common Stock will be duly authorized and, when issued and delivered to the Investor against full payment therefor in accordance with the terms of this Subscription Agreement, the Class A Common Stock will be validly issued, fully paid and non-assessable and will not have been issued in violation of or subject to any preemptive or similar rights created under OCA’s certificate of incorporation or bylaws (each, as amended on the Closing Date) or under the General Corporation Law of the State of Delaware or under any agreement or instrument to which OCA is a party.

c. This Subscription Agreement has been duly authorized, executed and delivered by OCA and, assuming that this Subscription Agreement constitutes the valid and binding agreement of the Investor and OCA, this Subscription Agreement is enforceable against OCA in accordance with its terms, except as may be limited or otherwise affected by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other laws relating to or affecting the rights of creditors generally, or (ii) principles of equity, whether considered at law or equity.

d. The issuance and sale of shares of Class A Common Stock and the compliance by OCA with all of the provisions of this Subscription Agreement and the consummation of the transactions contemplated herein will be done on accordance with the rules of the Nasdaq marketplace (“Nasdaq”) and will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of OCA or any of its subsidiaries pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which OCA or any of its subsidiaries is a party or by which OCA or any of its subsidiaries is bound or to which any of the property or assets of OCA is subject that would reasonably be expected to have a material adverse effect on the legal authority of OCA to timely comply in all material respects with the terms of this Subscription Agreement (a “Material Adverse Effect”); (ii) result in any violation of the provisions of the organizational documents of OCA; or (iii) result in any violation of any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over OCA or any of its properties that would reasonably be expected to have a Material Adverse Effect.

e. A copy of each form, report, statement, schedule, prospectus, proxy, registration statement and other document filed by OCA on or prior to the Closing Date (the “SEC Reports”) is available to the Investor (including via the SEC’s XXXXX system). XXX has timely filed the SEC Reports with the SEC through the date hereof. As of their respective filing dates, to the best of OCA’s knowledge, all SEC Reports complied in all material respects with the requirements of the Exchange Act applicable to the SEC Reports and the rules and regulations of the SEC promulgated thereunder applicable to the SEC Reports. None of the SEC Reports filed under the Exchange Act (except to the extent that information contained in any SEC Report has been superseded by a later timely filed SEC Report) contained, when filed or, if amended, as of the date of such amendment with respect to those disclosures that are amended, any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. The financial statements of OCA included in the SEC Reports, as applicable, comply in all material respects with applicable accounting requirements and the rules and regulations of the SEC with respect thereto as in effect at the time of filing, or, if amended, as of the date of such amendment, and fairly present in all material respects the financial position of OCA as of and for the dates thereof and the results of operations and cash flows for the periods presented, subject to (i) in the case of unaudited statements, to normal, year-end audit adjustments, and such consolidated financial statements have been prepared in conformity with United States generally accepted accounting principles applied on a consistent basis during the periods involved (“GAAP”) (except as may be disclosed therein or in the notes thereto, and except that the unaudited financial statements may not contain all footnotes required by GAAP), and (ii) changes to historical accounting policies of OCA in connection with any order, directive, guideline, comment or recommendation from the SEC that is applicable to OCA. There are no material outstanding or unresolved comments in comment letters from the staff of the SEC with respect to any of the SEC Reports. For the avoidance of doubt, any restatement of the financial statements of OCA and any amendments to previously filed SEC Reports or delays in filing SEC Reports, in connection with any guidance from the SEC following the date of this Agreement, shall not be deemed to constitute a breach of this Section 5(e). Additionally, for avoidance of doubt, any amendment or modification of any SEC Report (or any agreement filed as an exhibit to any SEC Report) from its initial filing date in a subsequent filing shall not be deemed to constitute a breach of this Section 5(e).

f. As of the date hereof, the authorized share capital of OCA consists of (i) 100,000,000 shares of Class A Common Stock, (ii) 10,000,000 shares of Class B common stock, par value $0.0001 per share (the “Class B Common Stock” and together with the Class A Stock, the “OCA Common Stock”), and (iii) 1,000,000 shares of preferred stock, par value $0.0001 per share (the “Preferred Stock”). As of the date of this Subscription Agreement, (i) no shares of Preferred Stock are issued and outstanding, (ii) 3,900,717 shares of Class A Common Stock are issued and outstanding, and (iii) 3,737,500 shares of Class B Common Stock are issued and outstanding. All issued and outstanding shares of OCA Common Stock have been duly authorized and validly issued.

g. Assuming the accuracy of the representations and warranties of the Investor, OCA is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority, self-regulatory organization or other person in connection with the execution, delivery and performance by OCA of this Subscription Agreement (including, without limitation, the issuance of shares of Class A Common Stock), other than (i) filings with the U.S. Securities and Exchange Commission (the “SEC”), (ii) filings required by applicable state securities laws, (iii) filings required by Nasdaq, or such other applicable stock exchange on which OCA’s or the Company’s common equity will be listed (the “Stock Exchange”), (iv) those required to consummate the Transaction as provided under the Transaction Agreement, and (v) those of which the failure to obtain would not be reasonably likely to have, individually or in the aggregate, a Material Adverse Effect.

h. As of the date hereof, there is no suit, action, proceeding or investigation pending or, to the knowledge of OCA, threatened against OCA by the Stock Exchange or the SEC, respectively, to prohibit the listing of shares of Class A Common Stock, or the registration of, when issued in connection with the closing of the Transaction, the Class A Common Stock under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

i. Assuming the accuracy of the Investor’s representations and warranties set forth in Section 6, no registration under the Securities Act of 1933, as amended (the “Securities Act”) is required for the offer and sale of shares of Class A Common Stock by OCA to the Investor hereunder. The shares of Class A Common Stock (i) were not offered to the Investor by any form of general solicitation or general advertising and (ii) are not being offered to the Investor in a manner involving a public offering under, or in a distribution in violation of, the Securities Act, or any state securities laws.

l. OCA acknowledges and agrees that, notwithstanding anything herein to the contrary, shares of Class A Common Stock may be pledged by the Investor in connection with a bona fide margin agreement, provided such pledge shall be (i) pursuant to an available exemption from the registration requirements of the Securities Act or (ii) pursuant to, and in accordance with, a registration statement that is effective under the Securities Act at the time of such pledge, and the Investor effecting a pledge of shares of Class A Common Stock shall not be required to provide OCA with any notice thereof; provided, however, that neither OCA, the Company or their respective counsels shall be required to take any action (or refrain from taking any action) in connection with any such pledge, other than providing any such lender of such margin agreement with an acknowledgment that shares of Class A Common Stock are not subject to any contractual prohibition on pledging or lock up, the form of such acknowledgment to be subject to review and comment by XXX in all respects.

6. Investor Representations and Warranties. The Investor represents and warrants to OCA that:

a. The Investor, or each of the funds managed by or affiliated with the Investor for which the Investor is acting as nominee, as applicable, (i) is a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act) or an institutional “accredited investor” (within the meaning of Rule 501(a)(1), (2), (3), (7), (8), (9), (12) or (13) of Regulation D under the Securities Act), in each case, satisfying the applicable requirements set forth on Schedule A hereto, (ii) is acquiring shares of Class A Common Stock only for its own account and not for the account of others, or if the Investor is subscribing for shares of Class A Common Stock as a fiduciary or agent for one or more investor accounts, each owner of such account is a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act) or an “accredited investor” (within the meaning of Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act), and the Investor has full investment discretion with respect to each such account, and the full power and authority to make the acknowledgements, representations and agreements herein on behalf of each owner of each such account, and (iii) is not acquiring shares of Class A Common Stock with a view to, or for offer or sale in connection with, any distribution thereof in violation of the Securities Act or any securities laws of the United States or any other jurisdiction. The Investor shall provide the requested information set forth on Schedule A following the signature page hereto and the information contained therein is accurate and complete. The Investor is not an entity formed for the specific purpose of acquiring shares of Class A Common Stock. The Investor further acknowledges that it is aware that the sale to it is being made in reliance on a private placement exempt from registration under the Securities Act and is acquiring shares of Class A Common Stock for its own account or for an account over which it exercises sole discretion for another qualified institutional buyer or accredited investor.

b. The Investor acknowledges and agrees that shares of Class A Common Stock are being offered in a transaction not involving any public offering within the meaning of the Securities Act and that the offer and sale of shares of Class A Common Stock has not been registered under the Securities Act or any other applicable securities laws.

The Investor acknowledges and agrees that it has been advised to consult legal counsel and tax and accounting advisors prior to making any offer, resale, transfer, pledge, transfer or disposition of any shares of Class A Common Stock.

c. The Investor’s acquisition and holding of shares of Class A Common Stock will not constitute or result in a non-exempt prohibited transaction under Section 406 of the Employee Retirement Income Security Act of 1974, as amended, Section 4975 of the Internal Revenue Code of 1986, as amended, or any applicable similar law.

d. The Investor acknowledges and agrees that the Investor has received such information as the Investor deems necessary in order to make an investment decision with respect to shares of Class A Common Stock, including, without limitation, with respect to OCA, the Transaction and the business of the Company and its subsidiaries. Without limiting the generality of the foregoing, the Investor acknowledges that it has reviewed the SEC Reports and other information as the Investor has deemed necessary to make an investment decision with respect to shares of Class A Common Stock. The Investor acknowledges and agrees that the Investor and the Investor’s professional advisor(s), if any, have had the full opportunity to ask such questions, including from the Company directly, receive such answers and obtain such information as the Investor and the Investor’s professional advisor(s), if any, have deemed necessary to make an investment decision with respect to shares of Class A Common Stock, including but not limited to access to marketing materials and a virtual data room containing information about the Company and its financial condition, results of operations, business, properties, management and prospects sufficient, in the Investor’s judgment, to enable the Investor to evaluate its investment. The Investor acknowledges that certain information provided by the Company was based on projections, and such projections were prepared based on assumptions and estimates that are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the projections. The Investor further acknowledges that it has reviewed or had the full opportunity to review all disclosure documents provided to such Investor in the offering of shares of Class A Common Stock and no statement or printed material which is contrary to such disclosure documents has been made or given to the Investor by or on behalf of OCA or the Company. Except for the representations, warranties and agreements of OCA expressly set forth in this Subscription Agreement, the Investor is relying exclusively on its, his or her own sources of information, investment analysis and due diligence (including professional advice it deemed appropriate) with respect to the Transaction, the transactions contemplated hereby, shares of Class A Common Stock and the business, condition (financial or otherwise), management, operations, properties and prospects of OCA and the Company, including, but not limited to, all business, legal, regulatory, accounting, credit and tax matters.

e. The Investor became aware of this offering of shares of Class A Common Stock solely by means of direct contact between the Investor, OCA, the Company or a representative of OCA or the Company, and shares of Class A Common Stock were offered to the Investor solely by direct contact between the Investor and OCA, the Company or a representative of OCA or the Company. The Investor did not become aware of this offering of shares of Class A Common Stock, nor were shares of Class A Common Stock offered to the Investor, by any other means and none of OCA, the Company or their respective representatives or any person acting on behalf of any of them acted as investment advisor, broker or dealer to the Investor. The Investor acknowledges that shares of Class A Common Stock (i) were not offered by any form of general solicitation or general advertising and (ii) are not being offered in a manner involving a public offering under, or in a distribution in violation of, the Securities Act, or any state securities laws.

f. The Investor acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of shares of Class A Common Stock, including, without limitation, those set forth in the SEC Reports. The Investor has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in shares of Class A Common Stock, and the Investor has had an opportunity to seek, and has sought such accounting, legal, business and tax advice as the Investor has considered necessary to make an informed investment decision and the Investor has made its own assessment and satisfied itself concerning relevant tax and other economic considerations relative to its purchase of shares of Class A Common Stock. The Investor (i) is an institutional account as defined in FINRA Rule 4512(c), (ii) is a sophisticated investor, experienced in investing in private equity transactions and capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities, and (iii) has exercised independent judgment in evaluating its participation in the purchase of shares of Class A Common Stock.

g. Alone, or together with any professional advisor(s), the Investor has adequately analyzed and fully considered the risks of an investment in shares of Class A Common Stock and determined that shares of Class A Common Stock are a suitable investment for the Investor and that the Investor is able at this time and in the foreseeable future to bear the economic risk of a total loss of the Investor’s investment in OCA. The Investor has determined based on its, his or her own independent review and such professional advice as the Investor deemed appropriate that its, his or her purchase of shares of Class A Common Stock and participation in the Transaction is fully consistent with its, his or her financial needs, objectives and condition and is a suitable investment for the Investor, notwithstanding the risks inherent in investing in or holding the subscribed shares of Class A Common Stock.

The Investor acknowledges specifically that a possibility of total loss exists.

h. In making its decision to purchase shares of Class A Common Stock, the Investor has relied solely upon independent investigation made by the Investor.

i. The Investor acknowledges and agrees that no federal or state agency has passed upon or endorsed the merits of the offering of shares of Class A Common Stock or made any findings or determination as to the fairness of this investment.

l. The Investor is not (i) a person or entity named on the List of Specially Designated Nationals and Blocked Persons, the Executive Order 13599 List, the Foreign Sanctions Evaders List, or the Sectoral Sanctions Identification List, each of which is administered by the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) or in any Executive Order issued by the President of the United States and administered by OFAC (collectively, the “OFAC Lists”), or a person or entity prohibited by any OFAC sanctions program, (ii) owned, directly or indirectly, or controlled by, or acting on behalf of, one or more persons that are named on the OFAC Lists; (iii) organized, incorporated, established, located, resident or born in, or a citizen, national or the government, including any political subdivision, agency or instrumentality thereof, of Cuba, Iran, North Korea, Russia, Syria, the Crimea region of Ukraine, the so-called Donetsk People’s Republic, the so-called Luhansk People’s Republic and any other Covered Region of Ukraine identified pursuant to Executive Order 14065, and non-government controlled areas of the Kherson and Zaporizhzhia region of Ukraine or any other country or territory embargoed or subject to substantial trade restrictions by the United States, (iv) a Designated National as defined in the Cuban Assets Control Regulations, 31 C.F.R.

XXX agrees to indemnify and hold harmless, to the extent permitted by law, the Investor, its directors, and officers, employees, and agents, and each person who controls the Investor (within the meaning of the Securities Act or the Exchange Act) and each affiliate of the Investor (within the meaning of Rule 405 under the Securities Act) from and against any and all losses, claims, damages, liabilities and expenses (including, without limitation, reasonable and documented attorneys’ fees) caused by any untrue or alleged untrue statement of material fact contained in any registration statement covering the shares of Class A Common Stock sold hereunder (the “Resale Registration Statement”), prospectus included in any Resale Registration Statement (“Prospectus”) or preliminary Prospectus or any amendment thereof 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, except insofar as the same are caused by or contained in any information furnished in writing to OCA by or on behalf of the Investor expressly for use therein.

b. The Investor agrees to indemnify and hold harmless OCA, its directors and officers and agents and each person who controls OCA (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including, without limitation, reasonable and documented attorneys’ fees) resulting from any untrue statement of material fact contained in the Resale Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any 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 or affidavit so furnished in writing by or on behalf of the Investor expressly for use therein. In no event shall the liability of the Investor be greater in amount than the dollar amount of the net proceeds received by such Investor upon the sale of shares of Class A Common Stock purchased pursuant to this Subscription Agreement giving rise to such indemnification obligation.

c. Any person entitled to indemnification herein shall (1) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and (2) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent. An indemnifying party who elects not to assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of legal counsel to any indemnified party a conflict of interest exists between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which (1) cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement), (2) does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation, or (3) contains any statement of fault or culpability.

d. The indemnification provided for under this Subscription Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director, employee, agent, affiliate or controlling person of such indemnified party and shall survive the transfer of shares of Class A Common Stock purchased pursuant to this Subscription Agreement.

e. If the indemnification provided under this Section 7 from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by or on behalf of, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 7 from any person who was not guilty of such fraudulent misrepresentation. In no event shall the liability of the Investor pursuant to this Section 7 be greater in amount than the dollar amount of the net proceeds received by such Investor upon the sale of shares of Class A Common Stock purchased pursuant to this Subscription Agreement giving rise to such indemnification obligation, and such obligations of the Investor shall be several and not joint.

8. Termination. This Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earliest to occur of (a) such date and time as the Transaction Agreement is terminated in accordance with its terms without being consummated or (b) upon the mutual written agreement of each of the parties hereto to terminate this Subscription Agreement (the termination events described in clauses (a)–(b) above, collectively, the “Termination Events”); provided that nothing herein will relieve any party from liability for any willful and material breach of any covenant, agreement, obligation, representation or warranty hereunder prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities or damages arising from any such willful and material breach. OCA shall notify the Investor in writing of the termination of the Transaction Agreement as promptly as practicable after the termination of the Transaction Agreement. Upon the occurrence of any Termination Event, this Subscription Agreement shall be void and of no further effect and any monies paid by the Investor to OCA in connection herewith shall promptly (and in any event within three (3) business days) following the Termination Event be returned to the Investor.

9. Trust Account Waiver. The Investor acknowledges that OCA is a blank check company with the powers and privileges to effect a merger, asset acquisition, reorganization or similar business combination involving OCA and one or more businesses or assets. The Investor further acknowledges that, as described in OCA’s final prospectus relating to its initial public offering dated January 14, 2021 (the “Final Prospectus”) available at xxx.xxx.xxx, substantially all of OCA’s assets consist of the cash proceeds of OCA’s initial public offering and private placement of its securities, and substantially all of those proceeds have been deposited in a trust account (the “Trust Account”) for the benefit of OCA, its public stockholders and the underwriters of OCA’s initial public offering. Except with respect to interest earned on the funds held in the Trust Account that may be released to OCA to pay its tax obligations, if any, the cash in the Trust Account may be disbursed only for the purposes set forth in the Final Prospectus. For and in consideration of OCA entering into this Subscription Agreement, the receipt and sufficiency of which are hereby acknowledged, the Investor, on behalf of itself and its representatives, hereby irrevocably waives any and all right, title and interest, or any claim of any kind it has or may have in the future, in or to any monies held in the Trust Account (or distributions therefrom to OCA’s public stockholders or to the underwriters of OCA’s initial public offering in respect of their deferred underwriting commissions held in the Trust Account), and agrees not to seek recourse against the Trust Account as a result of, or arising out of, this Subscription Agreement or the transactions contemplated hereby regardless of whether such claim arises based on contract, tort, equity or any other theory of legal liability; provided, however, that nothing in this Section 9 shall be deemed to limit the Investor’s right, title, interest or claim to any monies held in the Trust Account by virtue of its record or beneficial ownership of publicly traded Class A Common Stock acquired in an open market transaction, pursuant to a validly exercised redemption right with respect to any such Class A Common Stock, in accordance with OCA’s Amended and Restated Certificate of Incorporation, as amended in connection with the shareholder meeting of OCA on January 19, 2023 and as may be subsequently amended from time to time, and the Investment Management Trust Agreement between Continental Stock Transfer & Trust Company and OCA, dated January 14, 2021, except to the extent that the Investor has otherwise agreed in writing with OCA, the Company or any of their respective affiliates to not exercise such redemption right.

10. Miscellaneous.

a. Neither this Subscription Agreement nor any rights that may accrue to the Investor hereunder (other than shares of Class A Common Stock acquired hereunder solely in connection with a transfer of such shares of Class A Common Stock (other than a transfer in connection with a sale pursuant to either an effective registration statement or under Rule 144), if any) may be transferred or assigned. Notwithstanding the foregoing, after notifying OCA, Investor may assign its rights and obligations under this Subscription Agreement to one or more of its affiliates (including other investment funds or accounts managed or advised by the investment manager who acts on behalf of Investor) or, with the Company’s prior written consent, to another person, provided that this Subscription Agreement and any of the Investor’s rights and obligations hereunder may be assigned to any of its affiliates without the prior written consent of OCA; provided further that prior to such assignment, any such assignee shall agree in writing to be bound by the terms hereof. No such assignment shall relieve the Investor of its obligations hereunder if any such assignee fails to perform such obligations.

b. OCA may request from the Investor such additional information as OCA may deem necessary to register the resale of shares of Class A Common Stock and evaluate the eligibility of the Investor to acquire shares of Class A Common Stock, and the Investor shall promptly provide any such information as may be reasonably requested to the extent readily available. Without limiting the generality of the foregoing or any other covenants or agreements in this Subscription Agreement, the Investor acknowledges that OCA and the Company may file a copy of this Subscription Agreement with the SEC as an exhibit to a periodic report or a registration statement of OCA or the Company.

c. The Investor acknowledges that OCA, the Company and others will rely on the acknowledgments, understandings, agreements, representations and warranties contained in this Subscription Agreement, including Schedule A hereto. Prior to the Closing, the Investor agrees to promptly notify OCA and the Company in writing (including, for the avoidance of doubt, by email) if any of the acknowledgments, understandings, agreements, representations or warranties set forth in Section 6 above are no longer accurate in any material respect (other than those acknowledgments, understandings, agreements, representations and warranties qualified by materiality, in which case the Investor shall notify OCA and the Company if they are no longer accurate in any respect). The Investor acknowledges and agrees that each purchase by the Investor of shares of Class A Common Stock from OCA will constitute a reaffirmation of the acknowledgments, understandings, agreements, representations and warranties herein by the Investor as of the time of such purchase. OCA acknowledges that the Investor will rely on the acknowledgments, understandings, agreements, representations and warranties of OCA contained in this Subscription Agreement. Prior to the Closing, XXX agrees to promptly notify the Investor if they become aware that any of the acknowledgments, understandings, agreements, representations and warranties made by them set forth herein are no longer accurate in all material respects.

d. OCA is entitled to rely upon this Subscription Agreement and each is irrevocably authorized to produce this Subscription Agreement or a copy hereof to any interested party in any administrative or legal proceeding or official inquiry with respect to the matters covered hereby; provided, however, without limiting the generality of the foregoing and for the avoidance of doubt, in no event shall the Company be entitled to rely on any of the representations and warranties of OCA set forth in this Subscription Agreement.

e. All of the agreements, representations and warranties made by each party hereto in this Subscription Agreement shall survive the Closing.

f. This Subscription Agreement may not be terminated other than pursuant to the terms of Section 8 above. The Company is a third-party beneficiary of this Agreement. The provisions of this Subscription Agreement may not be modified, amended or waived except by an instrument in writing, signed by each of the parties hereto and the Company. No failure or delay of either party hereto in exercising any right or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such right or power, or any course of conduct, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the parties hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have hereunder.

g. This Subscription Agreement (including, without limitation, the schedule hereto) constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations and warranties, both written and oral, among the parties, with respect to the subject matter hereof. Except as set forth in Section 3(b), Section 6, Section 8, Section 10(c), Section 10(d), Section 10(f), this Section 10(g) and the last sentence of Section 10(k) with respect to the persons specifically referenced therein, this Subscription Agreement shall not confer any rights or remedies upon any person other than the parties hereto, and their respective successors and assigns, and the parties hereto acknowledge that such persons so referenced are third party beneficiaries of this Subscription Agreement with right of enforcement for the purposes of, and to the extent of, the rights granted to them, if any, pursuant to the applicable provisions.

h. Except as otherwise provided herein, this Subscription Agreement shall be binding upon, and inure to the benefit of the parties hereto and their heirs, executors, administrators, successors, legal representatives, and permitted assigns, and the agreements, representations, warranties, covenants and acknowledgments contained herein shall be deemed to be made by, and be binding upon, such heirs, executors, administrators, successors, legal representatives and permitted assigns.

i. If any provision of this Subscription Agreement shall be adjudicated by a court of competent jurisdiction to be invalid, illegal or unenforceable, the validity, legality or enforceability of the remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue in full force and effect.

j. This Subscription Agreement may be executed and delivered in one or more counterparts (including, without limitation, by facsimile or electronic mail or in .pdf) and by different parties in separate counterparts, with the same effect as if all parties hereto had signed the same document. All counterparts so executed and delivered shall be construed together and shall constitute one and the same agreement.

k. The parties hereto acknowledge and agree that irreparable damage would occur if any of the provisions of this Subscription Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties hereto shall be entitled to an injunction or injunctions to prevent breaches of this Subscription Agreement, without posting a bond or undertaking and without proof of damages, to enforce specifically the terms and provisions of this Subscription Agreement, this being in addition to any other remedy to which such party is entitled at law, in equity, in contract, in tort or otherwise. The parties hereto acknowledge and agree that the Company shall be entitled to seek to specifically enforce the Investor’s obligations to fund the Subscription Amount, OCA’s obligations under this Subscription Agreement and the provisions of the Subscription Agreement of which the Company is an express third party beneficiary, in each case, on the terms and subject to the conditions set forth herein.

l. This Subscription Agreement shall be governed by and construed in accordance with the laws of the State of Delaware (regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof) as to all matters (including any action, suit, litigation, arbitration, mediation, claim, charge, complaint, inquiry, proceeding, hearing, audit, investigation or reviews by or before any governmental entity related hereto), including matters of validity, construction, effect, performance and remedies.

m. Each party hereto hereby, and any person asserting rights as a third party beneficiary may do so only if it, irrevocably agrees that any action, suit or proceeding between or among the parties hereto, whether arising in contract, tort or otherwise, arising in connection with any disagreement, dispute, controversy or claim arising out of or relating to this Subscription Agreement or any related document or any of the transactions contemplated hereby or thereby (“Legal Dispute”) shall be brought only to the exclusive jurisdiction of the courts of the State of Delaware or the federal courts located in the State of Delaware, and each party hereto hereby consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such suit, action or proceeding and irrevocably waives, to the fullest extent permitted by law, any objection that it, he or she may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding that is brought in any such court has been brought in an inconvenient forum. During the period a Legal Dispute that is filed in accordance with this Section 10(M) is pending before a court, all actions, suits or proceedings with respect to such Legal Dispute or any other Legal Dispute, including any counterclaim, cross-claim or interpleader, shall be subject to the exclusive jurisdiction of such court. Each party hereto and any person asserting rights as a third party beneficiary may do so only if it hereby waives, and shall not assert as a defense in any Legal Dispute, that (a) such party is not personally subject to the jurisdiction of the above named courts for any reason, (b) such action, suit or proceeding may not be brought or is not maintainable in such court, (c) such party’s property is exempt or immune from execution, (d) such action, suit or proceeding is brought in an inconvenient forum, or (e) the venue of such action, suit or proceeding is improper. A final judgment in any action, suit or proceeding described in this Section 11(m) following the expiration of any period permitted for appeal and subject to any stay during appeal shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable laws. EACH OF THE PARTIES HERETO AND ANY PERSON ASSERTING RIGHTS AS A THIRD PARTY BENEFICIARY MAY DO SO ONLY IF IT IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT TO TRIAL BY JURY ON ANY CLAIMS OR COUNTERCLAIMS ASSERTED IN ANY LEGAL DISPUTE RELATING TO THIS SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY AND FOR ANY COUNTERCLAIM RELATING THERETO. IF THE SUBJECT MATTER OF ANY SUCH LEGAL DISPUTE IS ONE IN WHICH THE WAIVER OF JURY TRIAL IS PROHIBITED, NO PARTY HERETO NOR ANY PERSON ASSERTING RIGHTS AS A THIRD PARTY BENEFICIARY SHALL ASSERT IN SUCH LEGAL DISPUTE A NONCOMPULSORY COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. FURTHERMORE, NO PARTY HERETO NOR ANY PERSON ASSERTING RIGHTS AS A THIRD PARTY BENEFICIARY SHALL SEEK TO CONSOLIDATE ANY SUCH LEGAL DISPUTE WITH A SEPARATE ACTION OR OTHER LEGAL PROCEEDINGS IN WHICH A JURY TRIAL CANNOT BE WAIVED.

x. XXX agrees that it will use reasonable best efforts to cause the Company to grant to the Investor customary registration rights with respect to Company Common Stock, and that such shares of common stock will be included as “registrable securities” in a registration rights agreement to be entered into among the Investor, the Company and certain other parties in connection with the closing of the Transaction.

o. Any notice or communication required or permitted hereunder to be given to the Investor shall be in writing and either delivered personally, emailed or sent by overnight mail via a reputable overnight carrier, or sent by certified or registered mail, postage prepaid, to such address(es) or email address(es) set forth on the signature page hereto, and shall be deemed to be given and received (i) when so delivered personally, (ii) when sent, with no mail undeliverable or other rejection notice, if sent by email, or (iii) three (3) business days after the date of mailing to the address below or to such other address or addresses as the Investor may hereafter designate by notice given hereunder:

The Investor acknowledges and agrees that none of (i) any other investor pursuant to this Subscription Agreement or any other subscription agreement related to the private placement of shares of Class A Common Stock (including the investor’s respective affiliates or any control persons, officers, directors, employees, partners, agents or representatives of any of the foregoing) or (ii) any other party to the Transaction Agreement or any Non-Party Affiliate, shall have any liability to the Investor, or to any other investor, pursuant to, arising out of or relating to this Subscription Agreement or any other subscription agreement related to the private placement of shares of Class A Common Stock, the negotiation hereof or thereof or its subject matter, or the transactions contemplated hereby or thereby, including, without limitation, with respect to any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the purchase of shares of Class A Common Stock or with respect to any claim (whether in tort, contract or otherwise) for breach of this Subscription Agreement or in respect of any written or oral representations made or alleged to be made in connection herewith, as expressly provided herein, or for any actual or alleged inaccuracies, misstatements or omissions with respect to any information or materials of any kind furnished by OCA, the Company or any Non-Party Affiliate concerning OCA, the Company, any of their respective controlled affiliates, this Subscription Agreement or the transactions contemplated hereby.
