WHEREAS, at the Closing and after the Domestication Merger, MariaDB will merge with and into Irish Holdco by way of a cross-border merger (the “Merger”) and by virtue of the Merger, Irish Holdco will acquire all the assets and liabilities of MariaDB and MariaDB will be dissolved without going into liquidation in exchange for the issue to the shareholders of MariaDB of shares of capital in Irish Holdco as merger consideration with Irish Holdco continuing as the surviving entity following the Merger;

WHEREAS, as soon as is reasonably practicable following the Merger, the Company will be entered into liquidation (the “Liquidation”) pursuant to which the Company shall be liquidated and all assets (if any) transferred to Irish Holdco;

WHEREAS, in connection with the Transaction, Subscriber desires to subscribe for and purchase from Irish Holdco, following the Domestication Merger and immediately prior to the consummation of the Transaction, that number of shares of Irish Holdco’s Class A shares, par value $0.0001 per share (the “Shares”), set forth on the signature page hereto (the “Subscribed Shares”) for a purchase price of $9.50 per share (the “Per Share Price” and the aggregate of all Subscribed Shares at the Per Share Price being referred to herein as the “Purchase Price”), and Irish Holdco desires to issue and sell to Subscriber the Subscribed Shares in consideration of the payment of the Purchase Price by or on behalf of Subscriber to Irish Holdco at or prior to the Closing Date (as defined herein); and

NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions, herein contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

Section 1 Subscription. Subject to the terms and conditions hereof, at the Closing (as defined below), Subscriber hereby agrees to subscribe for and purchase, and Irish Holdco hereby agrees to issue and sell to Subscriber, upon the payment of the Purchase Price, the Subscribed Shares (such subscription and issuance, the “Subscription”). Subscriber acknowledges and agrees that the Subscribed Shares that will be purchased by Subscriber and issued by Irish Holdco pursuant hereto shall be shares of capital in an Irish public limited company (and not, for the avoidance of doubt, ordinary shares in a Cayman Islands exempted company).

Section 2 Closing.

(a) The consummation of the Subscription contemplated hereby (the “Closing”) shall occur on the closing date of the Transaction (the “Closing Date”), substantially concurrently with the consummation of the Transaction.

(b) At least five (5) Business Days before the anticipated Closing Date, the Company or Irish Holdco shall deliver written notice to Subscriber (the “Closing Notice”) specifying (i) the anticipated Closing Date and (ii) the wire instructions for delivery of the Purchase Price to Irish Holdco. No later than two (2) Business Days prior to the Closing Date, Subscriber shall deliver the Purchase Price for the Subscribed Shares by wire transfer of United States dollars in immediately available funds to the account specified by the Company or Irish Holdco in the Closing Notice, such funds to be held by Irish Holdco in escrow until the Closing, and no later than three (3) Business Days prior to the Closing Date deliver to the Company or Irish Holdco such information as is required in the Closing Notice in order for Irish Holdco to issue the Subscribed Shares to Subscriber, including, without limitation, the legal name of the person in whose name the Subscribed Shares are to be issued and a duly completed and executed Internal Revenue Service Form W-9 or appropriate Form W-8. Upon satisfaction (or, if applicable, waiver) of the conditions set forth in this Section 2, Irish Holdco shall deliver to Subscriber (i) at the Closing, the Subscribed Shares in book entry form, free and clear of any liens or other restrictions (other than those arising under this Subscription Agreement or applicable securities laws), in the name of Subscriber (or its nominee in accordance with its delivery instructions), and (ii) as promptly as practicable after the Closing, evidence from Irish Holdco’s transfer agent of the issuance to Subscriber of the Subscribed Shares on and as of the Closing Date. Notwithstanding the foregoing two sentences, if Subscriber informs the Company and Irish Holdco (1) that it is an investment company registered under the Investment Company Act of 1940, as amended, (2) that it is advised by an investment adviser subject to regulation under the Investment Advisers Act of 1940, as amended, or (3) that its internal compliance policies and procedures so require it, then, in lieu of the settlement procedures in the foregoing two sentences, the following shall apply: Subscriber shall deliver at 8:00 a.m. New York City time on the Closing Date (or as soon as practicable following receipt of evidence from Irish Holdco’s transfer agent of the issuance to Subscriber of the Subscribed Shares on and as of the Closing Date) the Purchase Price for the Subscribed Shares by wire transfer of United States dollars in immediately available funds to the account specified by the Company or Irish Holdco in the Closing Notice against delivery by Irish Holdco to Subscriber of the Subscribed Shares in book entry form, free and clear of any liens or other restrictions (other than those arising under applicable securities laws), in the name of Subscriber (or its nominee in accordance with its delivery instructions) and evidence from Irish Holdco’s transfer agent of the issuance to Subscriber of the Subscribed Shares on and as of the Closing Date. In the event that the consummation of the Transaction does not occur within ten (10) Business Days after the anticipated Closing Date specified in the Closing Notice, unless otherwise agreed to in writing by the Company or Irish Holdco, on the one hand, and Subscriber, on the other hand, Irish Holdco shall promptly (but in no event later than twelve (12) Business Days after the anticipated Closing Date specified in the Closing Notice) return the funds so delivered by Subscriber to Irish Holdco by wire transfer in immediately available funds to the account specified by Subscriber, and any book entries shall be deemed cancelled. Notwithstanding such return or cancellation, (x) a failure to close on the anticipated Closing Date shall not, by itself, be deemed to be a failure of any of the conditions to Closing set forth in this Section 2 to be satisfied or waived on or prior to the Closing Date, and (y) unless and until this Subscription Agreement is terminated in accordance with Section 7 herein, Subscriber shall remain obligated (A) to redeliver funds to Irish Holdco in escrow following the Company’s or Irish Holdco’s delivery to Subscriber of a new Closing Notice and (B) to consummate the Closing upon satisfaction of the conditions set forth in this Section 2. For the purposes of this Subscription Agreement, “Business Day” means any day other than a Saturday, Sunday or any other day on which commercial banks are required or authorized to close in the State of New York. Any funds held in escrow by Irish Holdco will be uninvested, and Subscriber shall not be entitled to any interest earned thereon. Upon delivery of the Subscribed Shares to Subscriber (or its nominee or custodian, if applicable), the Purchase Price shall be immediately released to Irish Holdco from escrow.

(a) The Company is and will be, as applicable, duly organized, validly existing and in good standing under the laws of the Cayman Islands as of the Closing Date.

For purposes of this Subscription Agreement, a “Company Material Adverse Effect” means an event, change, development, occurrence, condition or effect with respect to the Company and its subsidiaries, taken together as a whole (on a consolidated basis), that, individually or in the aggregate, would reasonably be expected to have a material adverse effect on the Company’s ability to consummate the transactions contemplated hereby, including the issuance and sale of the Subscribed Shares. For purposes of this Subscription Agreement, an “Irish Holdco Material Adverse Effect” means an event, change, development, occurrence, condition or effect with respect to Irish Holdco and its subsidiaries, taken together as a whole (on a consolidated basis), that, individually or in the aggregate, would reasonably be expected to have a material adverse effect on Irish Holdco’s ability to consummate the transactions contemplated hereby, including the issuance and sale of the Subscribed Shares.

(d) This Subscription Agreement has been duly authorized, executed and delivered by each of the Company and Irish Holdco, and assuming the due authorization, execution and delivery of the same by the other parties hereto, this Subscription Agreement shall constitute the valid and legally binding obligation of each of the Company and Irish Holdco, enforceable against each of the Company and Irish Holdco in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and similar laws affecting creditors generally and by the availability of equitable remedies.

(e) Assuming the accuracy of the representations and warranties of Subscriber and the other parties hereto, the execution and delivery of this Subscription Agreement, the issuance and sale of the Subscribed Shares and the compliance by each of the Company and Irish Holdco with the provisions of this Subscription Agreement and the consummation of the transactions contemplated herein 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 each of the Company or Irish Holdco, as applicable pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which each of the Company or Irish Holdco, as applicable, is a party or by which each of the Company or Irish Holdco, as applicable, is bound or to which any of the property or assets of each of the Company or Irish Holdco, as applicable, is subject; (ii) the organizational documents of each of the Company or Irish Holdco, as applicable; or (iii) any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over each of the Company or Irish Holdco, as applicable, or any of their properties that, in the case of clauses (i) and (iii), would reasonably be expected to have a Company Material Adverse Effect or Irish Holdco Material Adverse Effect, as applicable.

(f) Each of the Company and Irish Holdco, as applicable, is not in default or violation (and no event has occurred which, with notice or the lapse of time or both, would constitute a default or violation) of any term, condition or provision of (i) the organizational documents of each of the Company or Irish Holdco, as applicable, (ii) any loan or credit agreement, guarantee, note, bond, mortgage, indenture, lease or other agreement, permit, franchise or license to which, as of the date of this Subscription Agreement, each of the Company or Irish Holdco, as applicable, is a party or by which each of the Company’s or Irish Holdco’s, as applicable, properties or assets are bound or (iii) any statute or any judgment, order, rule or regulation of any court or governmental agency, taxing authority or regulatory body, domestic or foreign, having jurisdiction over each of the Company or Irish Holdco, as applicable, or any of its properties, except, in the case of clauses (ii) and (iii), for defaults or violations that have not had and would not be reasonably likely to have, individually or in the aggregate, a Company Material Adverse Effect or Irish Holdco Material Adverse Effect, as applicable. For the avoidance of doubt, in the case of clause (iii), an alleged default or

4

violation of any statute or any judgment, order, rule or regulation will not have a Company Material Adverse Effect or Irish Holdco Material Adverse Effect, as applicable, if such alleged default or violation resulted or would result from the application of any statute or any judgment, order, rule or regulation in accordance with market practice for special purpose acquisition companies at the time such application was made.

(g) Assuming the accuracy of the representations and warranties of Subscriber and the other parties hereto, each of the Company and Irish Holdco, as applicable, are 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 (including The New York Stock Exchange (the “Stock Exchange”)) or other person in connection with the execution, delivery and performance of this Subscription Agreement (including, without limitation, the issuance of the Subscribed Shares), other than (i) filings required by applicable state securities laws, (ii) the filing of the Registration Statement pursuant to Section 5 below, (iii) those required by the Stock Exchange, including with respect to obtaining stockholder approval, (iv) those required to consummate the Transaction as provided under the Transaction Agreement, (v) the filing of notification under the ▇▇▇▇-▇▇▇▇▇-▇▇▇▇▇▇ Antitrust Improvements Act of 1976, if applicable, and (vi) the failure of which to obtain would not be reasonably likely to have a Company Material Adverse Effect or Irish Holdco Material Adverse Effect, as applicable.

(j) Subscriber acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Subscribed Shares. Subscriber has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Subscribed Shares, and Subscriber has had an opportunity to seek, and has sought, such accounting, legal, business and tax advice as Subscriber has considered necessary to make an informed investment decision.

(k) Subscriber has adequately analyzed and fully considered the risks of an investment in the Subscribed Shares and determined, based on its own independent review and such professional advice as Subscriber deems appropriate that Subscriber’s purchase the Subscribed Shares (i) are fully consistent with its financial needs, objectives and condition, (ii) comply and fully consistent with all investment policies, guidelines and other restrictions applicable to Subscriber and (iii) are a fit, proper and suitable investment for Subscriber notwithstanding the substantial risks inherent in investing in or holding the Subscribed Shares. Subscriber is able at this time and in the foreseeable future to bear the economic risk of a total loss of Subscriber’s investment in the Company, Irish Holdco or the Acquired Companies. Subscriber acknowledges specifically that a possibility of total loss exists.

(l) Subscriber understands and agrees that no federal or state agency has passed upon or endorsed the merits of the offering of the Subscribed Shares or made any findings or determination as to the fairness of this investment.

Subscriber is not an institution that accepts currency for deposit and that (a) has no physical presence in the jurisdiction in which it is incorporated or in which it is operating and (b) is unaffiliated with a regulated financial group that is subject to consolidated supervision (a “Shell Bank”) or providing banking services to a Shell Bank. Subscriber represents that if it is a financial institution subject to the Bank Secrecy Act (31 U.S.C. Section 5311 et seq.), as amended by the USA PATRIOT Act of 2001 and its implementing regulations (collectively, the “BSA/PATRIOT Act”), that Subscriber maintains policies and procedures reasonably designed to comply with applicable obligations under the BSA/PATRIOT Act. Subscriber also represents that, to the extent required by applicable law, it maintains, either directly or through the use of a third-party administrator, policies and procedures reasonably designed for the screening of any investors in Subscriber against Sanctions-related lists of blocked or restricted persons. Subscriber further represents and warrants that (i) the funds held by Subscriber and used to purchase the Subscribed Shares were not directly or indirectly derived from or related to any activities that may contravene U.S. federal, state or non-U.S. anti-money laundering, anti-corruption or Sanctions laws and regulations or activities that may otherwise be deemed criminal and (ii) any returns from Subscriber’s investment will not be used to finance any illegal activities. For purposes of this Subscription Agreement, “Sanctioned Person” means at any time any person or entity with whom dealings are restricted, prohibited, or sanctionable under any Sanctions (as defined below), including as a result of being: (a) listed on any Sanctions-related list of designated or blocked or restricted persons; (b) that is a national of, the government of, or any agency or instrumentality of the government of, or resident in, or organized under the laws of, a country or territory that is the target of comprehensive Sanctions from time to time (as of the date of this Subscription Agreement, Cuba, Iran, North Korea, Syria, and the Crimea region); or (c) a relationship of

(o) Subscriber does not have, as of the date hereof, and during the 30-day period immediately prior to the date hereof Subscriber has not entered into, any “put equivalent position” as such term is defined in Rule 16a-1 under the Exchange Act or Short Sale positions with respect to the securities of the Company. Notwithstanding the foregoing, in the case of a Subscriber that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of Subscriber’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of Subscriber’s assets, the representation set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Subscribed Shares covered by this Subscription Agreement.

(p) Subscriber is not currently (and at all times through Closing will refrain from being or becoming) a member of a “group” (within the meaning of Section 13(d)(3) or Section 14(d)(2) of the Exchange Act or any successor provision) including any group acting for the purpose of acquiring, holding, voting or disposing of equity securities of the Company (within the meaning of Rule 13d-5(b)(1) under the Exchange Act).

Part 800.224) in which the national or subnational governments of a single foreign state have a substantial interest (as defined in 31 C.F.R. Part 800.244) and that will acquire a substantial interest in Irish Holdco as a result of the purchase and sale of Subscribed Shares hereunder such that a declaration to the Committee on Foreign Investment in the United States would be mandatory under 31 C.F.R. Part 800.401, and no foreign person will have control (as defined in 31 C.F.R. Part 800.208) over Irish Holdco from and after the Closing as a result of the purchase and sale of the Subscribed Shares hereunder.

Section 5 Registration of Subscribed Shares.

(a) Irish Holdco shall use its commercially reasonable efforts to, within thirty (30) Business Days after the Closing Date (the “Filing Date”), file with the Commission (at Irish Holdco’s sole cost and expense) a registration statement registering the resale of the Subscribed Shares (the “Registration Statement”), and Irish Holdco shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof, and in any event, no later than sixty (60) calendar days following the Filing Date; provided, that such date shall be extended to one hundred twenty (120) calendar days after the Filing Date if the Registration Statement is reviewed by, and comments thereto are provided from, the Commission; provided, further, that if such day falls on a Saturday, Sunday or other day that the Commission is closed for business, such deadline shall be extended to the next Business Day on which the Commission is open for business (the “Effectiveness Deadline”). Notwithstanding the foregoing, if Irish Holdco is notified in writing by the Commission that the Registration Statement will not be “reviewed” or subject to further review, Irish Holdco shall use its commercially reasonable efforts to have the Registration Statement declared effective within ten (10) Business Days of receipt of such notice. Irish Holdco will use its commercially reasonable efforts to provide a draft of the Registration Statement to the undersigned for review (but not comment) at least two (2) Business Days in advance of filing the Registration Statement; provided that, for the avoidance of doubt, in no event shall Irish Holdco be required to delay or postpone the filing of such Registration Statement as a result of or in connection with Subscriber’s review. Notwithstanding the foregoing, if the Commission prevents Irish Holdco from including any or all of the shares proposed to be registered under the Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of the Subscribed Shares by the applicable stockholders or otherwise, such Registration Statement shall register for resale such number of Subscribed Shares which is equal to the maximum number of Subscribed Shares as is permitted by the Commission. In such event, the number of Subscribed Shares to be registered for each selling stockholder named in the Registration Statement shall be reduced pro rata among all such selling stockholders. Irish Holdco agrees that, except for such times as Irish Holdco is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, Irish Holdco will use commercially reasonable efforts to cause such Registration Statement to remain effective with respect to Subscriber until the earlier of (i) two (2) years from the date of issuance of the Subscribed Shares, (ii) the date on which all of the Subscribed Shares shall have been sold, or (iii) on the first date on which the undersigned can sell all of its Subscribed Shares (or shares received in exchange therefor) under Rule 144 of the Securities Act without limitation as to the manner of sale or the amount of such securities that may be sold. For as long as the Registration Statement shall remain effective pursuant to the immediately preceding sentence, Irish Holdco will use commercially reasonable efforts to file all reports, and provide all customary and reasonable cooperation, necessary to enable the undersigned to resell the Subscribed Shares pursuant to the Registration Statement or Rule 144 of the Securities Act (when Rule 144 of the Securities Act becomes available to Irish Holdco), as applicable, qualify the Subscribed Shares for listing on the applicable stock exchange on which Irish Holdco’s Shares are then listed, and update or amend the Registration Statement as necessary to include the Subscribed Shares. The undersigned agrees to disclose its beneficial ownership, as determined in accordance with Rule 13d-3 of the Exchange Act, of Subscribed Shares to Irish Holdco (or its successor) upon request to assist Irish Holdco in making the determination described above. Irish Holdco’s obligations to include the Subscribed Shares in the Registration Statement are contingent upon Subscriber furnishing in writing to the Company and Irish Holdco such information regarding

11

Subscriber, the securities of Irish Holdco held by Subscriber and the intended method of disposition of the Subscribed Shares as shall be reasonably requested by the Company or Irish Holdco to effect the registration of the Subscribed Shares, and Subscriber shall execute such documents in connection with such registration as the Company or Irish Holdco may reasonably request that are customary of a selling stockholder in similar situations, including providing that Irish Holdco shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement during any customary blackout or similar period or as permitted hereunder. In the case of the registration effected by Irish Holdco pursuant to this Subscription Agreement, the Company or Irish Holdco shall, upon reasonable request, inform Subscriber as to the status of such registration. In no event shall Subscriber be identified as a statutory underwriter in the Registration Statement unless requested by the Commission. If the Commission requests that Subscriber be identified as a statutory underwriter in the Registration Statement, Subscriber shall have an opportunity to withdraw from the Registration Statement. Subscriber shall not be entitled to use the Registration Statement for an underwritten offering of Subscribed Shares. Notwithstanding anything to the contrary contained herein, Irish Holdco may delay or postpone filing of such Registration Statement, and from time to time require Subscriber not to sell under the Registration Statement or suspend the use or effectiveness of any such Registration Statement if it determines that in order for the registration statement to not contain a material misstatement or omission, an amendment thereto would be needed, or if such filing or use could materially affect a bona fide business or financing transaction of the Company or Irish Holdco or would require premature disclosure of information that could materially adversely affect the Company or Irish Holdco (each such circumstance, a “Suspension Event”); provided, that, (y) Irish Holdco shall not so delay filing or so suspend the use of the Registration Statement for a period of more than ninety (90) consecutive days or more than a total of one hundred-twenty (120) calendar days, in each case in any three hundred sixty (360) day period and (z) Irish Holdco shall use commercially reasonable efforts to make such registration statement available for the sale by the undersigned of such securities as soon as practicable thereafter.

(b) At its expense, Irish Holdco shall advise Subscriber within two (2) Business Days: (i) of the issuance by the Commission of any stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose; (ii) of the receipt by Irish Holdco of any notification with respect to the suspension of the qualification of the Subscribed Shares included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and (iii) subject to the provisions in this Subscription Agreement, of the occurrence of a Suspension Event.

(c) For purposes of this Section 5, “Subscribed Shares” shall mean, as of any date of determination, the Subscribed Shares (as defined in the recitals to this Subscription Agreement) and any other equity security issued or issuable with respect to the Subscribed Shares by way of share split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event, and “Subscriber” shall include any affiliate of the undersigned Subscriber to which the rights under this Section 5 shall have been duly assigned.

(d) Upon receipt of any written notice from Irish Holdco of the happening of any Suspension Event during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or related prospectus contains any untrue statement of a material fact or omits to state any 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 undersigned agrees that (i) it will immediately discontinue offers and sales of the Subscribed Shares under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until the undersigned receives copies of a supplemental or amended prospectus (which Irish Holdco agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by Irish Holdco that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written notice delivered by Irish Holdco unless otherwise required by law, subpoena or regulatory request or requirement. If so directed by Irish Holdco, the undersigned will deliver to Irish Holdco or, in the undersigned’s sole discretion destroy, all copies of the prospectus covering the Subscribed Shares in the undersigned’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Subscribed Shares shall not apply (w) to the extent the undersigned is required to retain a copy of such prospectus (A) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (B) in accordance with a bona fide pre-existing document retention policy or (x) to copies stored electronically on archival servers as a result of automatic data back-up.

12

(e) Indemnification.

13

(f) If the Subscribed Shares acquired hereunder are eligible to be sold without restriction under, and without the requirement for Irish Holdco to be in compliance with the current public information requirements of, Rule 144, then at Subscriber’s request, Irish Holdco will reasonably cooperate with Irish Holdco’s transfer agent, such that any remaining restrictive legend set forth on such Subscribed Shares will be removed in connection with a sale of such shares.

Section 6 Short Sales. Subscriber hereby agrees that, from the date of this Subscription Agreement, none of Subscriber, its controlled affiliates, or any person or entity acting on behalf of Subscriber or any of its controlled affiliates or pursuant to any understanding with Subscriber or any of its controlled affiliates will engage in any Short Sales with respect to securities of the Company prior to the Closing. For purposes of this Subscription Agreement, “Short Sales” shall include, without limitation, all “short sales” as defined in Rule 200 promulgated under Regulation SHO under the Exchange Act, and all types of direct and indirect stock pledges (other than pledges in the ordinary course of business as part of prime brokerage arrangements), forward sale contracts, options, puts, calls, swaps and similar arrangements (including on a total return basis), and sales and other transactions through non-U.S. broker dealers or foreign regulated brokers. Notwithstanding the foregoing, (i) nothing herein shall prohibit other entities under common management with Subscriber that have no knowledge of this Subscription Agreement or of Subscriber’s participation in the Transaction (including Subscriber’s controlled affiliates and/or affiliates) from entering into any Short Sales and (ii) in the case of a Subscriber that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Subscriber’s assets and the portfolio managers have no knowledge of the investment decisions made by the portfolio managers managing other portions of such Subscriber’s assets, the covenant set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Subscribed Shares covered by this Subscription Agreement.

14

Section 7 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 hereto in respect thereof, upon the earlier to occur of (a) such date and time as the Transaction Agreement is terminated in accordance with its terms, (b) upon the mutual written agreement of the parties hereto to terminate this Subscription Agreement, (c) if, on the Closing Date of the Transaction, any of the conditions to Closing set forth in Section 2 of this Subscription Agreement have not been satisfied as of the time required hereunder to be so satisfied or waived by the party entitled to grant such waiver and, as a result thereof, the transactions contemplated by this Subscription Agreement are not consummated, or (d) written notice by any party to the other parties to terminate this Subscription Agreement if the transactions contemplated by this Subscription Agreement are not consummated on or prior to June 30, 2023; provided, that nothing herein will relieve any party from liability for any intentional breach hereof 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 such breach. The Company or Irish Holdco shall notify Subscriber of the termination of the Transaction Agreement promptly after the termination thereof.

Section 8 Trust Account Waiver. Subscriber hereby acknowledges that the Company has established a trust account (the “Trust Account”) containing the proceeds of its initial public offering (the “IPO”) and from certain private placements occurring simultaneously with the IPO (including interest accrued from time to time thereon) for the benefit of the Company’s public stockholders and certain other parties (including the underwriters of the IPO). For and in consideration of the Company entering into this Subscription Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Subscriber hereby (a) agrees that it does not now and shall not at any time hereafter have any right, title, interest or claim of any kind in or to any assets held in the Trust Account, and shall not make any claim against the Trust Account, regardless of whether such claim arises as a result of, in connection with or relating in any way to this Subscription Agreement or any other matter, and regardless of whether such claim arises based on contract, tort, equity or any other theory of legal liability (any and all such claims are collectively referred to hereafter as the “Released Claims”), (b) irrevocably waives any Released Claims that it may have against the Trust Account now or in the future as a result of, or arising out of, any negotiations, contracts or agreements with the Company or Irish Holdco, and (c) will not seek recourse against the Trust Account for any reason whatsoever; provided, however, that nothing in this Section 8 shall be deemed to limit any Subscriber’s right to distributions from the Trust Account in accordance with the Company’s amended and restated certificate of incorporation in respect of the Shares of the Company acquired by any means other than pursuant to this Subscription Agreement.

Each of the parties also agrees that delivery of any process, summons, notice or document to a party hereof in compliance with Section 9(a) of this Subscription Agreement shall be effective service of process for any action, suit or proceeding in a Designated Court with respect to any matters to which the parties have submitted to jurisdiction as set forth above.

(s) This Subscription Agreement may only be enforced against, and any claim, action, suit or other legal proceeding based upon, arising out of, or related to this Subscription Agreement, or the negotiation, execution or performance of this Subscription Agreement, may only be brought against the entities that are expressly named as parties or third party beneficiaries hereto and then only with respect to the specific obligations set forth herein with respect to such party or third party beneficiary. No past, present or future director, officer, employee, incorporator, manager, member, partner, stockholder, affiliate, agent, attorney or other representative of any party hereto or of any affiliate of any party hereto, or any of their successors or permitted assigns, shall have any liability for any obligations or liabilities of any party hereto under this Subscription Agreement or for any claim, action, suit or other legal proceeding based on, in respect of or by reason of the transactions contemplated hereby.

(t) Notwithstanding anything in this Subscription Agreement to the contrary, the Company and Irish Holdco shall not publicly disclose the name of Subscriber, its investment adviser or any of their respective affiliates, Subscriber’s beneficial ownership of the Subscribed Shares, or the nature of Subscriber’s commitments, arrangements and understandings under and relating to this Subscription Agreement in any press release issued by the Company or Irish Holdco, any Form 8-K filed by the Company or Irish Holdco with the Commission in connection with the execution and delivery of the Transaction Agreement or the transactions contemplated thereby and the Registration Statement (as defined in the Transaction Agreement), except to the extent required by the federal securities laws, exchange rules, the Commission or any other securities authorities or any rules and regulations promulgated thereby or with Subscriber’s consent. Subscriber will promptly provide any information reasonably requested by the Company or Irish Holdco for any regulatory application or filing made or approval sought in connection with the Transaction (including filings with the Commission). The Company and Irish Holdco have disclosed to Subscriber certain non-public information regarding the Transaction, including the material terms of the transactions contemplated hereby (and by the Other Subscription Agreements), and Subscriber acknowledges its agreement to treat such information confidentially until such time as all such “material non-public information” (within the meaning of applicable securities laws) is either publicly disclosed by the Company or Irish Holdco or deemed by the Company or Irish Holdco to be no longer relevant. In accordance therewith, the Company or Irish Holdco shall, by 9:30 a.m., New York City time, on the first (1st) Business Day immediately following the date of this Subscription Agreement, issue one or more press releases or file with the Commission a Current Report on Form 8-K disclosing, to the extent not previously publicly disclosed, such material non-public information unless the Company determines, in compliance with applicable laws and regulations, that any of such information is no longer material.

(u) If any change in the number of Company’s Shares shall occur between the date of this Subscription Agreement and immediately prior to the Closing by reason of any reclassification, recapitalization, stock split (including reverse stock split) or combination, exchange or readjustment of shares, or any stock dividend, the number of Subscribed Shares issued to Subscriber shall be appropriately adjusted to reflect such change. The Domestication Merger shall not result in any adjustment.

(v) The obligations of Subscriber under this Subscription Agreement are several and not joint with the obligations of any Other Subscriber or any other investor under the Other Subscription Agreements, and Subscriber shall not be responsible in any way for the performance of the obligations of any Other Subscriber under this Subscription Agreement or any Other Subscriber or other investor under the Other Subscription Agreements. The decision of Subscriber to purchase Subscribed Shares pursuant to this Subscription Agreement has been made by Subscriber independently of any Other Subscriber or any other investor and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company, Irish Holdco, MariaDB or any of their respective subsidiaries which may have been made or given by any Other Subscriber or investor or by any agent or employee of any Other Subscriber or investor, and neither Subscriber nor any of its agents or employees shall have any liability to any Other Subscriber or investor (or any other person) relating to or arising from any such information, materials, statements or opinions. Nothing contained herein or in any Other Subscription Agreement, and no action

taken by Subscriber or investor pursuant hereto or thereto, shall be deemed to constitute Subscriber and Other Subscribers or other investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that Subscriber and Other Subscribers or other investors are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Subscription Agreement and the Other Subscription Agreements. Subscriber acknowledges that no Other Subscriber has acted as agent for Subscriber in connection with making its investment hereunder and no Other Subscriber will be acting as agent of Subscriber in connection with monitoring its investment in the Subscribed Shares or enforcing its rights under this Subscription Agreement. Subscriber shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Subscription Agreement, and it shall not be necessary for any Other Subscriber or investor to be joined as an additional party in any proceeding for such purpose.

The language used in this Subscription Agreement will be deemed to be the language chosen by the parties hereto to express their mutual intent, and no rules of strict construction will be applied against any party. Unless the context otherwise requires, (i) all references to Sections, Annexes or Exhibits are to Sections, Annexes or Exhibits contained in or attached to this Subscription Agreement, (ii) each accounting term not otherwise defined in this Subscription Agreement has the meaning assigned to it in accordance with GAAP, (iii) words in the singular or plural include the singular and plural and pronouns stated in either the masculine, the feminine or neuter gender shall include the masculine, feminine and neuter, (iv) the use of the word “including” in this Subscription Agreement shall be by way of example rather than limitation, and (v) the word “or” shall not be exclusive.
