INSTRUCTIONS

A.	Special Conditions

Time in which to Make an Election. To be effective, a properly completed Election Form and your share certificates (if applicable) must be received by Computershare, the Exchange Agent, no later than 5:00 p.m. (New York City time) on July 10, 2024, unless the offer is extended or earlier terminated (the “Election Deadline”). The Election Deadline is based on the closing of the Offer, which, as of the date of the mailing of this Election Form, remains subject to various conditions, including, among other things, the Acceptance Condition. Bidco and MariaDB will publicly announce any extensions of the Election Deadline in a press release, on their websites and in a filing with the SEC. Holders of MariaDB Shares who hold such shares in certificated form must also include with their completed Election Form the certificate(s) representing all their MariaDB Shares to which the Election Form relates. Holders of MariaDB Shares who hold such shares in electronic, book-entry form do not need to include any certificate(s) and simply need to return a completed Election Form. You understand and acknowledge that you will not receive the Offer consideration you have selected unless and until the Offer has closed and the Exchange Agent has received from you all necessary documentation.

WHILE MARIADB SHAREHOLDERS HAVE UNTIL THE EXPIRATION TIME TO COMPLETE THEIR TENDERS, IF BIDCO CANNOT DETERMINE, AT THE ACCEPTANCE UNCONDITIONAL TIME, (AS IT MAY BE EXTENDED AS DESCRIBED IN THE OFFER DOCUMENT) THAT (I) THE ACCEPTANCE CONDITION HAS BEEN SATISFIED, FULFILLED OR, TO THE EXTENT PERMITTED, WAIVED, AND (II) ALL OTHER CONDITIONS WILL BE SATISFIED, FULFILLED OR, TO THE EXTENT PERMITTED, WAIVED BY THE EXPIRATION TIME, THE OFFER WILL LAPSE AND THERE WILL BE NO POST-ACCEPTANCE UNCONDITIONAL PERIOD.

THEREFORE, MARIADB SHAREHOLDERS ARE STRONGLY ENCOURAGED TO TENDER THEIR MARIADB SHARES AS SOON AS POSSIBLE AND PRIOR TO THE ACCEPTANCE CUT-OFF TIME.

2.	Certificates and Shares held by the Exchange Agent. The Election Form will indicate the number of MariaDB Shares you hold either in certificated form or in electronic, book-entry form.

3.	Election Options. On page 3 of the Election Form, under “Election Options,” indicate whether you would like to receive in exchange for each of your MariaDB shares, (i) the Cash Offer or (ii) the Unlisted Unit Alternative. You may not select a mixture of both.

Change or Withdrawal of Acceptance and/or Election. A holder of MariaDB Shares who has accepted the Offer and made an election may at any time prior to the Election Deadline may withdraw such acceptance and/or change such election by written notice to the Exchange Agent in the case of a withdrawal of an acceptance or, in order to change an election, by submitting to the Exchange Agent a revised Election Form, properly completed and signed, that is received by the Exchange Agent prior to the Election Deadline.

Joint Forms of Election. Holders of MariaDB Shares who make a joint election will be considered to be a single holder of such shares. An Election Form including such a joint election (“Joint Election Form”) may be submitted only by persons submitting certificates registered in different forms of the same name (e.g., “John Smith” on one certificate and “J. Smith” on another). If the Election Form is submitted as a Joint Election Form, each record holder of MariaDB Shares covered thereby must properly sign the Election Form in accordance with Instruction B.1, attaching additional sheets if necessary. The signatures of such holders will be deemed to constitute a certification that the persons submitting a Joint Election Form are eligible to do so.

Forms of Election for Nominees. Any record holder of MariaDB Shares who is a nominee may submit one or more Election Forms, indicating on the form or forms a combination of elections covering up to the aggregate number of MariaDB Shares owned by such record holder. However, upon the request of Bidco, any such record holder will be required to certify to the satisfaction of Bidco that such record holder holds such MariaDB Shares as nominee for the beneficial owners of such shares. Each beneficial owner for whom such an Election Form is so submitted will be treated as a separate shareholder of MariaDB for purposes of allocation of Topco Rollover Units and cash payments to be issued upon closing of the Offer.

Shares as to Which No Acceptance of Election is Made. If the Exchange Agent does not receive a properly completed Election Form from you at or prior to the Election Deadline (together with any share certificates representing the MariaDB Shares covered by your election if applicable), then you will be deemed not to have accepted the Offer and will not receive the Offer consideration.

If the Offer becomes or is declared unconditional in all respects and sufficient acceptances have been received at the Expiration Time (and in all cases within four months of the date of this document), following closing of the Offer, Bidco intends to apply the provisions of Sections 456 to 460 of the Companies Act 2014 to acquire compulsorily any outstanding MariaDB Shares not acquired or agreed to be acquired pursuant to the Offer or otherwise. The default election for all MariaDB Shareholders during this compulsory acquisition process will be for the Cash Offer.

If you return this form properly completed (together with the required share certificates, if applicable) but fail to make an election between the Cash Offer and the Unlisted Unit Alternative for any reason, you will be deemed to have accepted the Cash Offer in full in respect of your MariaDB Shares. If you return this form properly completed (together with the required share certificates, if applicable) but make an election for both the Cash Offer and the Unlisted Unit Alternative for any reason, you will be deemed to have accepted the Cash Offer in full in respect of your MariaDB Shares.

Lapse or Withdrawal of the Offer. In the event of lapse or withdrawal of the Offer, the Exchange Agent will promptly return certificates representing the MariaDB Shares. In such event, MariaDB Shares held through nominees are expected to be available for sale or transfer promptly following the lapse or withdrawal of the Offer. Certificates representing MariaDB Shares held directly by MariaDB Shareholders will be returned by registered mail.

Investor Questionnaire. If you wish to select the Unlisted Unit Alternative, you should return, along with a properly completed Election Form electing the Unlisted Unit Alternative, a completed response letter (“Response Letter”) to the Investor Questionnaire delivered to you along with this form. Returning a completed Response Letter along with this form will be deemed to have indicated your interest in receiving the Unlisted Unit Alternative, but you will not have formally elected the Unlisted Unit Alternative at that time. Following review by Bidco of your Response Letter, you will receive the Offering Memorandum and a signature page to the Topco LLCA for execution. Only upon receipt by the Exchange Agent of your executed signature page to the Topco LLCA will you have formally elected the Unlisted Unit Alternative. Failure to complete these additional requirements will result in you being unable to receive the Unlisted Unit Alternative.

4.	How do I accept the Offer and make an election if my MariaDB Shares are held in “street name” by my bank, brokerage firm or other nominee?

If you hold your MariaDB Shares in “street name” through a bank, brokerage firm or other nominee (a “nominee”) you should instruct such nominee to accept the Offer (if you wish to do so) and as to what election to make on your behalf by carefully following the instructions that you will receive from your nominee. Acceptance of the Offer and/or an election will not be made on your behalf absent your instructions. You may be subject to an earlier deadline for accepting the Offer and/or making your election. Please contact your nominee with any questions.

5.	What is the deadline for accepting the Offer and making an election?

To be effective, a properly completed Election Form must be received by the Exchange Agent no later than 5:00 p.m. (New York City time) on July 10, 2024, unless extended (the “Election Deadline”). The Election Deadline is based on the closing of the Offer, which remains subject to various conditions, including, among other things, the Acceptance Condition. Bidco and MariaDB will publicly announce any extensions of the Election Deadline in a press release, on their websites and in a filing with the SEC.

THEREFORE, MARIADB SHAREHOLDERS ARE STRONGLY ENCOURAGED TO TENDER THEIR MARIADB SHARES AS SOON AS POSSIBLE AND PRIOR TO THE ACCEPTANCE CUT-OFF TIME.

Holders of MariaDB Shares who hold such shares in certificated form must also include with their completed Election Form the certificate(s) representing all their MariaDB Shares to which the Election Form relates. Holders of MariaDB Shares who hold such shares in electronic, book-entry form do not need to include any certificate(s) and simply need to return the completed Election Form. You understand and acknowledge that you will not receive the Offer consideration unless and until the Offer closes and the Exchange Agent has received from you all necessary documentation.

6.	What if I do not send a form of election or it is not received?

If the Exchange Agent does not receive a properly completed Election Form from you at or prior to the Election Deadline (together with any share certificates representing the MariaDB Shares covered by your election if applicable), then you will be deemed not to have accepted the Offer and will not receive the Offer consideration.

7.	What does it mean if I receive more than one set of election materials?

You may receive additional Election Forms with respect to MariaDB Shares held by you in another manner or in another name. For example, you may own some MariaDB Shares directly as a shareholder of record and other MariaDB Shares through a broker or you may own MariaDB Shares through more than one broker. In these situations, you will receive multiple sets of election materials. You must complete, sign, date and return all of the Election Forms or follow the instructions for any alternative election procedure on each Election Form you receive in order to accept the Offer and make an election for all of the MariaDB Shares you own. Each Election Form you receive comes with its own return envelope; make sure you return each Election Form in the return envelope that accompanies that Election Form.

8.	Can I withdraw my acceptance and/or change my election after my Election Form has been submitted?

Yes. A holder of MariaDB Shares who has accepted the Offer and made an election may at any time prior to the Election Deadline can change such election by submitting to the Exchange Agent a revised Election Form, properly completed and signed, that is received by the Exchange Agent prior to the Election Deadline.

9.	Am I guaranteed to receive what I ask for on the Election Form?

If you elect for the Cash Offer – yes, you are guaranteed to receive the cash consideration if the Offer closes.

If you elect for the Unlisted Unit Alternative – no, you are not guaranteed to receive the Unlisted Unit Alternative. If the aggregate number of Topco Rollover Units to be issued to all Electing Shareholders exceeds the Rollover Threshold then each Electing Shareholder’s number of Topco Rollover Units to which they would otherwise have been entitled will be reduced on a pro-rated basis (based on the relative holdings of all of the Electing Shareholders of MariaDB Shares as of immediately prior to the Closing Date), and the consideration for each MariaDB Share that is not exchanged for Topco Rollover Units will be paid in cash in accordance with the terms of the Cash Offer as described in paragraph 7 of Part 2 of Appendix 1 of the Offer Document.

Bidco may in its sole discretion, withdraw the Unlisted Unit Alternative if there are any Electing Shareholders whose election to receive the Unlisted Unit Alternative will require registration of the Topco Rollover Units under US securities law (and there is not an applicable exemption for each such Electing Shareholder) (the “Rollover Withdrawal Right”). In the event Bidco exercises its Rollover Withdrawal Right, the Unlisted Unit Alternative will lapse, no Topco Rollover Units will be issued and the consideration payable in respect of each tendered MariaDB Share will be settled in cash in accordance with the terms of the Cash Offer. The Offer will be open for at least ten business days after the announcement of Bidco’s exercise of its Rollover Withdrawal Right. For the avoidance of doubt, the exercise by Bidco of the Rollover Withdrawal Right shall not otherwise affect any validly received tenders, nor shall it constitute a variation of the Offer. You will be guaranteed to receive the cash consideration with respect to your MariaDB shares.

In addition, if you wish to receive the Unlisted Unit Alternative you will be required to (i) provide a completed Response Letter along with your Election Form and (ii) following receipt of the Offering Memorandum (if applicable), execute a signature page to the Topco LLCA by the Election Deadline. Failure to complete these additional requirements will result in you being unable to receive the Unlisted Unit Alternative.

10.	IF I ACCEPT THE OFFER, HOW WILL I RECEIVE THE OFFER CONSIDERATION?

If you are the record holder of your MariaDB Shares, after receiving the proper documentation from you and determining the proper allocations of consideration to be paid or issued to MariaDB shareholders, the Exchange Agent will forward to you a bank check for the cash to which you are entitled, less all applicable tax withholdings. If your MariaDB shares are held in “street name” by your bank, broker or other nominee, you will receive instructions from your bank, broker or other nominee as to how to submit a form of election and how to effect the surrender of your “street name” shares in order to receive the applicable consideration for those shares. Please contact your nominee for information on how you will receive the Offer consideration.

Physical certificates representing Topco Rollover Units will not be issued pursuant to the Unlisted Unit Alternative. Rather, each Electing Shareholder’s name will be entered on the Unit Ownership Ledger of Topco in respect of the Topco Rollover Units to which such Electing Shareholder becomes entitled pursuant to the Unlisted Unit Alternative.

11.	What happens if I sell or transfer my MariaDB shares after I have made an election?

If you are the record holder and wish to sell or transfer your MariaDB shares after you have properly made an election, you must provide written notice received by the Exchange Agent prior to the Election Deadline withdrawing your election with respect to all or the portion of your MariaDB Shares that you wish to sell or transfer. If your MariaDB Shares are held through a bank, broker or other nominee, you must contact your nominee to revoke your election and effect such transfer.

12.	What if I cannot locate my share certificate(s)?

If your certificate(s) representing MariaDB shares has (have) been lost, stolen or destroyed, contact MariaDB’s Transfer Agent, Computershare at 1-866-644-4127 (U.S. telephone numbers) or 781-575-2906 (Local and Outside U.S. Telephone numbers) for instruction prior to submitting the Election Form.

13.	What are the tax consequences of the receipt the Offer consideration?

A MariaDB Shareholder who is not resident or ordinarily resident or temporarily non-resident in Ireland, and who does not hold the MariaDB Shares in connection with a trade or business carried on in Ireland through a branch or agency, should not be subject to Irish tax on the consideration they receive in respect of the Offer. Other MariaDB Shareholders may have a liability to Irish tax.

For US federal income tax purposes, there will be tax consequences arising in connection with your sale of MariaDB Shares in the Offer. How you will be taxed will depend on a number of factors including, but not limited to, when you acquired the MariaDB Shares and if such MariaDB Shares were acquired pursuant to the exercise of a stock option. The tax implications of participating in the Offer are complex.

You should consult with your own legal, investment and tax advisors to determine the potential benefits, burdens and other consequences of the Offer particular to you, including the US federal, state, local, non-US and other tax consequences of participating in the Offer.

The above is provided for general information only. For an outline of the material Irish and US federal income tax consequences of the Offer, please see Appendix 4. It is recommended that you consult an appropriate independent adviser in respect of your tax treatment in relation to the Offer.
