Subject Company: Angel Pond Holdings Corporation

Filer’s Commission File Number: 1-40382

Date: October 24, 2022

To: Shareholders of MariaDB that are parties to the Shareholders’ Agreement.

From: MariaDB Corporation Ab

Dear Valued Shareholders:

In January 2022, MariaDB Corporation Ab (MariaDB) entered into a Business Combination Agreement (BCA) with Angel Pond Holdings Corporation (APHC) and various wholly-owned subsidiaries of APHC (APHC and its subsidiaries collectively will be referred to as Angel Pond). The BCA describes the terms and conditions of the business combination transaction where MariaDB and Angel Pond will ultimately merge. After completion of the merger, you and the other shareholders of MariaDB, collectively, will become the majority shareholders of MariaDB plc, the new post-merger Irish company that is expected to have publicly traded stock on the New York Stock Exchange. The Registration Statement on Form S-4, as amended, for the merger has been declared effective by the U.S. Securities and Exchange Commission and is available for review at the website that MariaDB has set up for shareholders relating to the Extraordinary General Meeting (EGM) to be held on October 26, 2022.

The website is located at: [______]

The password to the webpage is: [______]

MariaDB’s Board of Directors has summoned you and other MariaDB shareholders to the EGM. At that meeting, MariaDB’s shareholders will vote to approve the merger with Angel Pond, as described in the BCA and Common Draft Terms as previously described in the notice of meeting you should have previously received.

Investors who have invested in MariaDB’s preferred stock financings have joined in the MariaDB Shareholders’ Agreement (Shareholder Agreement) in connection with their investment. Employees and consultants who have exercised stock options have been required to sign adherence agreements pursuant to which they also become parties to the Shareholder Agreement. This email describes certain provisions of the Shareholder Agreement to which you are a party and how that will impact you in connection with MariaDB’s merger with Angel Pond and your obligation to vote in FAVOR of the merger and not exercise redemption rights (if any):

Shareholder Agreement to Vote in FAVOR of the Merger and Not to Exercise Redemption Rights

Section 16(C) of the Shareholder Agreement provides, among other things, if certain conditions are satisfied, you as a shareholder must:

•

Vote at the EGM in favor of an “Angel Pond Merger” (as such is defined in the Shareholder Agreement and as the one described above qualifies); and

•

Not require redemption of your MariaDB securities in connection with an Angel Pond Merger, as may be possible, under any terms of MariaDB securities or applicable law, including the Finnish Companies Act.

The conditions that must be satisfied by the provisions of Section 16(C) described above are that the Angel Pond Merger must be approved by: (i) a majority of MariaDB’s Board of Directors; (ii) each of the “Major Investors” (as defined in the Shareholder Agreement); and (iii) holders of a majority of MariaDB’s ordinary shares and preference shares, voting together as a single class, with holders of preference shares voting on an as converted basis and all holders of Series D preference shares being deemed to vote in favor of an Angel Pond Merger.

Under existing support agreements with a number of shareholders and the prior approvals by MariaDB’s Board of Directors and Major Investors, all of the conditions required by Section 16(C) either have been or will be satisfied prior to or at the time of the EGM. This will require you as a MariaDB shareholder under the Shareholder Agreement to vote your shares in favor of the Angel Pond Merger, and not to exercise redemption rights.

We also may be following up with you soon regarding how best for you to vote at the EGM. In this regard, attached is a Power of Attorney that authorizes Kelly Olson, our Vice President of Finance, and the Chairperson of the EGM, each alone, to represent you and vote your shares at the meeting. The easiest way to fulfill your obligation to vote in support of the meeting will be to complete and return the Power of Attorney to us (at the email address below).

We look forward to completing the merger with Angel Pond and are excited about our future as a publicly traded company

To return your Power of Attorney to us, or if you have any questions about the foregoing, please contact us at: merger@mariadb.com, and we will revert back with an answer as soon as practicable. A copy of your power of attorney should be sent to SGovashiri@perkinscoie.com.

Sincerely,
