3 ELECTION OPTIONS: On page 2 of this Stock/Cash Election Form and Letter of Transmittal, you may indicate whether you would like to receive, in exchange for your shares of HarborOne Bancorp, Inc. common stock, the Stock Election Consideration, the Cash Election Consideration or a combination of the Stock Election Consideration and the Cash Election Consideration.

HarborOne Bancorp, Inc. shareholders who are deemed to have made a non-election may receive all cash, all stock or a mix of cash/stock consideration, depending upon the elections of other HarborOne Bancorp, Inc. shareholders.

NOMINEES: Any record holder of shares of HarborOne Bancorp, Inc. common stock who is a nominee may submit one or more Stock/Cash Election Forms and Letters of Transmittal indicating on the form or forms a combination of elections covering up to the aggregate number of shares of HarborOne Bancorp, Inc. common stock owned by such record holder. However, upon the request of Eastern Bankshares, Inc., such record holders will be required to certify to the satisfaction of Eastern Bankshares, Inc. that such record holder holds such shares of HarborOne Bancorp, Inc. common stock as nominee for the beneficial owners of such shares.

5. REVOCATION OR CHANGE OF STOCK/CASH ELECTION FORM: Any Stock/Cash Election Form and Letter of Transmittal may be revoked or changed by written notice from the person submitting such form to the Exchange Agent for the merger, but to be effective, such notice must be received by the Exchange Agent at or prior to the Election Deadline. Eastern Bankshares, Inc. will have the discretion, which it may delegate to the Exchange Agent, to determine whether any revocation or change is received on a timely basis and whether any such revocation or change has been properly made.

6. SURRENDER OF CERTIFICATE(S): For any election contained herein to be effective, this Stock/Cash Election Form and Letter of Transmittal must be accompanied by any certificate(s) evidencing your shares and any required accompanying evidence of authority (see Instruction 11).

8. TERMINATION OF MERGER: In the event of termination of the Merger Agreement, the Exchange Agent will promptly return certificates representing shares HarborOne Bancorp, Inc. common stock after being notified of such termination by Eastern Bankshares, Inc. or HarborOne Bancorp, Inc. In such event, shares of HarborOne Bancorp, Inc. common stock held through nominees are expected to be available for sale or transfer promptly following the termination of the Merger Agreement.

10. EVIDENCE OF SHARES/CHECK ISSUED IN THE SAME NAME: If the shares in book entry form representing HarborOne Bancorp, Inc. common stock are to be evidenced and/or the check is to be issued in the same name as the surrendered certificate is registered, this Stock/Cash Election Form and Letter of Transmittal should be completed and signed exactly as the surrendered certificate is registered. Signature guarantees are not required if the certificate(s) surrendered herewith are submitted by the registered owner of such shares who has not completed the section entitled “Special Issuance/Payment Instructions” or are for the account of an Eligible Institution, as defined below. If any of the shares surrendered hereby are owned by two or more joint owners, all such owners must sign this Stock/Cash Election Form and Letter of Transmittal exactly as written on the face of the certificate(s). If any shares are registered in different names on several certificates, it will be necessary to complete, sign and submit as many separate Stock/Cash Election Forms and Letters of Transmittal as there are different registrations.
