Treatment as Wages or Compensation. No amounts paid or payable in connection with this Option shall constitute wages or compensation for purposes of any applicable law, if ever, prior to the date on which such amount has been earned,
vested and become payable in accordance with the terms of this Agreement and the Plan. No such amount shall be treated as wages or compensation for purposes of any employee or other benefit plan of the Company and its Affiliates except to the extent
and at the time provided in the respective employee or other benefit plan.

 By this exercise, I agree (i) to provide such additional documents as you may require pursuant to the
terms of the Eliem Therapeutics, Inc. 2019 Equity Incentive Plan (the “2019 Plan”), (ii) to provide for the payment by me to you (in the manner designated by you) of your withholding obligation, if any, relating to the

years after the date of grant of this option or within one year after such Shares are issued upon exercise of this option. I further agree that this Notice of Exercise may be delivered via facsimile, electronic mail (including pdf or any electronic
signature complying with the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act or other applicable law) or other transmission method and shall be deemed to have been duly and validly delivered and be valid and effective for all
purposes. 
  

	1 	 Shares must meet the public trading requirements set forth in the option agreement. 

	2 	 Shares must meet the public trading requirements set forth in the option. Shares must be valued in accordance
with the terms of the option being exercised, and must be owned free and clear of any liens, claims, encumbrances or security interests. Certificates must be endorsed or accompanied by an executed assignment separate from certificate.

 I hereby make the following certifications and representations with respect to the number of
Shares listed above, which are being acquired by me for my own account upon exercise of the option as set forth above: 
 I acknowledge that
the Shares have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), and are deemed to constitute “restricted securities” under Rule 701 and Rule 144 promulgated under the
Securities Act. I warrant and represent to the Company that I have no present intention of distributing or selling said Shares, except as permitted under the Securities Act and any applicable state securities laws. 

I hereby represent and warrant that (1) I have been furnished with all information which I deem necessary to evaluate the merits and
risks of the purchase of the Shares; (2) I have had the opportunity to ask questions concerning the Shares and the Company and all questions posed have been answered to my satisfaction; (3) I have been given the opportunity to obtain any
additional information I deem necessary to verify the accuracy of any information obtained concerning the Shares and the Company; and (4) I have such knowledge and experience in financial and business matters that I am able to evaluate the
merits and risks of purchasing the Shares and to make an informed investment decision relating thereto 
 I understand that because the
Shares have not been registered under the Securities Act, I must continue to bear the economic risk of the investment for an indefinite time and the Shares cannot be sold unless the Shares are subsequently registered under applicable federal and
state securities laws or an exemption from such registration requirements is available. 
 I agree that I will in no event sell or
distribute or otherwise dispose of all or any part of the Shares unless (1) there is an effective registration statement under the Securities Act and applicable state securities laws covering any such transaction involving the Shares or
(2) the Company receives an opinion of my legal counsel (concurred in by legal counsel for the Company) stating that such transaction is exempt from registration or the Company othe1wise satisfies itself that such transaction is exempt from
registration. 
 I have considered the Federal, state and local income tax implications of the exercise of my stock option and the purchase
and subsequent sale of the Shares. 
 I further acknowledge that I will not be able to resell the Shares for at least 90 days after the
stock of the Company becomes publicly traded (i.e., subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934) under Rule 701 and that more restrictive conditions apply to affiliates of the
Company under Rule 144. 
 I further acknowledge and agree that I will be party to and deemed a “Key Holder” under the Amended and
Restated Voting Agreement with the Company (as amended from time to time), a copy of which is included hereto as Exhibit A (the “Voting Agreement”). 

I further acknowledge that all certificates representing any of the Shares subject to the provisions of the option shall have endorsed thereon
appropriate legends reflecting the foregoing limitations, as well as any legends reflecting restrictions pursuant to the 2019 Plan, the Company’s Certificate of Incorporation, the Company’s Bylaws and/or applicable securities laws. 

I further agree that, if required by the Company (or a representative of the underwriters) in connection with the first underwritten
registration of the offering of any securities of the Company under the Securities Act, I will not sell, dispose of, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the
same economic effect as a sale with respect to any shares of Common Stock or other securities of the Company for a period of 180 days 

 
following the effective date of a registration statement of the Company filed under the Securities Act (or such longer period as the underwriters or the Company shall request to facilitate
compliance with FINRA Rule 2711 or NYSE Member Rule 472 or any successor or similar rule or regulation) (the “Lock-Up Period”). I further agree to execute and deliver such other
agreements as may be reasonably requested by the Company or the underwriters that are consistent with the foregoing or that are necessary to give further effect thereto. In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of such period. 
  

			
	 Very truly yours,
