EQUITY ADJUSTMENT NOTICE

This notice (this “Notice”) describes certain amendments that are being made to the Restricted Share Agreement(s) and/or Contribution and Restricted Share Agreement(s) (each, as amended from time to time, your “Award Agreement(s)”) between you and Rallybio Holdings, LLC (the “LLC”) and to the restricted common units and/or incentive units you hold under such Award Agreement(s) (collectively, your “Award(s)”) in connection with the initial public offering (the “IPO”) of shares of common stock of Rallybio Corporation (“Rallybio”) and the dissolution of the LLC (the “Dissolution”) undertaken pursuant to that certain Plan of Liquidation and Dissolution of Rallybio Holdings, LLC entered into by the LLC on or about July 22, 2021 (the “Plan of Dissolution”) in connection with the IPO. The LLC, its subsidiaries, and Rallybio are collectively referred to in this Notice as the “Company.”

In connection with the Dissolution and the IPO, the LLC will dissolve and distribute all of the common stock of Rallybio (“Rallybio Shares”) to the unitholders of the LLC, all vested and unvested restricted common units and incentive units will be cancelled and Rallybio Shares will be distributed in respect of such cancelled units, and Rallybio Shares are expected to become publicly traded on the Nasdaq Global Market.

You are receiving this Notice because you and/or persons related to you (which we together refer to as “you” or the “Participant”) currently hold restricted common units and/or incentive units issued pursuant to your Award Agreement(s) and the Rallybio Holdings, LLC 2018 Share Plan (as amended from time to time, the “2018 Plan”) that will be cancelled in connection with the Dissolution. The purpose of this Notice is to inform you of certain amendments that are being made to the terms of your Award(s) and that, notwithstanding anything to the contrary in your Award Agreement(s), the 2018 Plan and/or the operating agreement of the LLC (as amended from time to time, the “LLC Agreement”) or any other plan or agreement applicable to you or to which you are a party, will apply to your Award(s) as of and following the effective time of this Notice, as described below.

1. Effective Time; Defined Terms.

a. The adjustments described in this Notice, in their entirety, are effective as of the consummation of the Dissolution (the “Effective Time”) and are to be effected by the Plan of Dissolution. For the avoidance of any doubt, in the event that the Effective Time does not occur or your Award(s) are not outstanding as of immediately prior to the Effective Time, the treatment described herein shall not apply.

b. Capitalized terms used and not defined herein have the respective meanings ascribed to such terms in the 2018 Plan, the LLC Agreement or your Award Agreement(s), in each case, as applicable. To the extent that the restricted common units and/or incentive units under your Award(s) (or any portion thereof) are cancelled and Rallybio Shares are distributed to you in

connection with the Dissolution, references in the governing documents to the “Company” shall be construed to refer to (or to also include) Rallybio, and references in the governing documents to the “Board” shall be construed to refer to (or to also include) the board of directors or the compensation committee of the board of directors of Rallybio, in each case, to the extent necessary or appropriate to give effect to such distribution and the transactions described herein, in each case, as determined by Company in its sole discretion. In no event shall the transactions contemplated herein or any restructuring prior to, or in connection with, the IPO, including the cancellation of restricted common units and incentive units of the LLC and distribution of Rallybio Shares in connection with the Dissolution, constitute a “Change of Control” or a “Sale of the Company” for purposes of such restricted common units and/or incentive units or the Rallybio Shares distributed to you.

2. Organizational Transactions. In connection with the Dissolution, restricted common units and/or incentive units in the LLC will be cancelled and Rallybio Shares will be distributed in respect of such cancelled units. If the restricted common units and/or incentive units with respect to which Rallybio Shares are received were unvested at the time of such cancellation and distribution, such Rallybio Shares will be issued in the form of unvested restricted stock under, and subject to the terms of, the Rallybio Corporation 2021 Equity Incentive Plan. Such unvested Rallybio Shares will be subject to the same vesting schedule and transfer restrictions which applied to the unvested restricted common units and/or incentive units to which they relate.

a. Restricted Common Units. If you hold restricted common units, the restricted common units will be cancelled and you will receive restricted Rallybio Shares in accordance with the Plan of Dissolution. Exhibit A sets forth information regarding the number of restricted Rallybio Shares to be distributed to you in respect of restricted common units, if any.
