Participation Agreement

Name:                               

Section 1.Eligibility.

You have been designated as eligible to participate in the Structure Therapeutics Inc. Severance and Change in Control Plan (the “Plan”), a copy of which is attached to this Participation Agreement (this “Participation Agreement”).  Capitalized terms not explicitly defined in this Participation Agreement but defined in the Plan shall have the same definitions as in the Plan.  You will receive the benefits set forth below if you meet all the eligibility requirements set forth in the Plan, including, without limitation, executing the required Release within the applicable time period set forth therein and allowing such Release to become effective in accordance with its terms.  Notwithstanding the schedule for provision of benefits as set forth below, the schedule and timing of payment of any benefits under this Participant Agreement is subject to any delay in payment that may be required under Section 5 of the Plan.

Section 2.Change in Control Severance Benefits.

If you are terminated in a Covered Termination that occurs during the Change in Control Period, you will receive the severance benefits set forth in this Section 2.  All severance benefits described herein are subject to standard deductions and withholdings.

(a)Base Salary.  You shall receive a cash payment in an amount equal to [         ]¹ months (the “Severance Period”) of payment of your Base Salary.  The Base Salary payment will be paid to you in a lump sum cash payment no later than the second regular payroll date following the later of (i) the effective date of the Release or (ii) the Closing, but in any event not later than March 15 of the year following the year in which your Separation from Service occurs.

(b)Bonus Payment.  You will be entitled to [     ]² of the annual target cash bonus established for you, if any, pursuant to the annual performance bonus or annual variable compensation plan established by the Committee (or any authorized committee or designee thereof) for the year in which your Covered Termination occurs.  If at the time of the Covered Termination you are eligible for the annual target cash bonus for the year in which the Covered Termination occurs, but the target percentage (or target dollar amount, if specified as such in the applicable bonus plan) for such bonus has not yet been established for such year, the target percentage shall be the target percentage established for you for the preceding year (but adjusted, if necessary, for your position for the year in which the Covered Termination occurs). For the avoidance of doubt, the amount of the annual target cash bonus to which you are entitled under this Section 2(b) will be calculated: (1) assuming all articulated performance goals for such bonus (including, but not limited to, corporate and individual performance, if applicable), for the year of the Covered Termination was achieved at target levels; (2) as if you had provided services for the

​

​

​

entire year for which the bonus relates; and (3) ignoring any reduction in your Base Salary that would give rise to your right to resignation for Good Reason (such bonus to which you are entitled under this Section 2(b), the “Annual Target Cash Bonus Severance Payment”).  The Annual Target Cash Bonus Severance Payment shall be paid in a lump sum cash payment no later than the second regular payroll date following the later of (i) the effective date of the Release or (ii) the Closing, but in any event not later than March 15 of the year following the year in which your Separation from Service occurs.

(c)Payment of Continued Group Health Plan Benefits.  If you timely elect continued group health plan continuation coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”) following your Covered Termination date, the Company Group shall pay directly to the carrier the full amount of your COBRA premiums on your behalf for your continued coverage under the Company Group’s group health plans, including coverage for your eligible dependents, until the earliest of (i) the end of the Severance Period following your Covered Termination date, (ii) the expiration of your eligibility for the continuation coverage under COBRA, or (iii) the date when you become eligible for substantially equivalent health insurance coverage in connection with new employment (such period from your termination date through the earliest of (i) through (iii), the “COBRA Payment Period”). Upon the conclusion of such period of insurance premium payments made by the Company Group, you will be responsible for the entire payment of premiums (or payment for the cost of coverage) required under COBRA for the duration of your eligible COBRA coverage period, if any.  For purposes of this Section, (1) references to COBRA shall be deemed to refer also to analogous provisions of state law and (2) any applicable insurance premiums that are paid by the Company Group shall not include any amounts payable by you under an Internal Revenue Code Section 125 health care reimbursement plan, which amounts, if any, are your sole responsibility. You agree to promptly notify the Company Group as soon as you become eligible for health insurance coverage in connection with new employment or self-employment.

Notwithstanding the foregoing, if at any time the Company Group determines, in its sole discretion, that it cannot provide the COBRA premium benefits without potentially incurring financial costs or penalties under applicable law (including, without limitation, Section 2716 of the Public Health Service Act), then in lieu of paying COBRA premiums directly to the carrier on your behalf, the Company Group will instead pay you on the last day of each remaining month of the COBRA Payment Period a fully taxable cash payment equal to the value of your monthly COBRA premium for the first month of COBRA coverage, subject to applicable tax withholding (such amount, the “Special Severance Payment”), such Special Severance Payment to be made without regard to your election of COBRA coverage or payment of COBRA premiums and without regard to your continued eligibility for COBRA coverage during the COBRA Payment Period.  Such Special Severance Payment shall end upon expiration of the COBRA Payment Period.

(d)Equity Acceleration.  The vesting and exercisability of each outstanding unvested stock option and other stock award, as applicable, that you hold covering Shares as of your Covered Termination date (each, an “Equity Award”) that is subject to time-vesting shall be accelerated in full and any reacquisition or repurchase rights held by the Company Group in respect of Shares issued pursuant to any time-vesting Equity Award granted to you shall lapse in full.  To the extent your Covered Termination occurs prior to the Change in Control, the acceleration set

​

forth in this Section 2(d) shall be contingent and effective upon the Change in Control and your Equity Awards will remain outstanding following your Covered Termination to give effect to such acceleration as necessary.  For the avoidance of doubt, any Equity Awards subject to performance-vesting shall vest and become exercisable according to their individual award agreements.

Section 3.Non-Change in Control Severance Benefits.

If you are terminated in a Covered Termination that occurs at a time that is not during the Change in Control Period, you will receive:

(a)the base salary cash payment described in Section 2(a) above, but the Severance Period for purposes of calculating such benefits shall be [        ]³ months;

(b)[the Annual Target Cash Bonus Severance Payment described in Section 2(b) above, except that it will be equal to 100% of the annual target cash bonus established for you, if any, pursuant to the annual performance bonus or annual variable compensation plan established by the Committee (or any authorized committee or designee thereof) for the year in which your Covered Termination occurs;]⁴

(c)the COBRA benefits described in Section 2(c) above, but the Severance Period for purposes of calculating such benefits shall be [       ]⁵ months; and

(d)acceleration of the vesting and exercisability (as applicable) of any then-outstanding time-vesting Equity Awards to the extent such awards were scheduled to vest during the [     ]⁶-month period following your Covered Termination date based solely on your continued employment with the Company Group, had you remained employed by the Company Group through such date, such that such portion of your then-outstanding time-vesting Equity Awards will be deemed immediately vested and exercisable (as applicable) as of the date immediately preceding your Covered Termination date.

You shall not be eligible to receive any other benefits under the Plan except as described in this Section 3.

For the avoidance of doubt, in no event shall you be entitled to benefits under both Section 2 above and this Section 3. If you are eligible for severance benefits under both Section 2 and this Section 3, you shall receive the benefits set forth in Section 2 and such benefits shall be reduced by any benefits previously provided to you under this Section 3.

If (i) in connection with a Change in Control, any outstanding unvested Equity Award that you hold will not be assumed or continued by the successor or acquiror entity (or its

​

​

parent company) in such Change in Control or substituted for a similar award of the successor or acquiror entity (or its parent company) (a “Terminating Award”) and (ii) your continued employment with the Company Group has not terminated as of immediately prior to the effective time of such Change in Control, then you will become vested with respect to any then-unvested portion of such Terminating Award, effective immediately prior to, but subject to the consummation of such Change in Control. With respect to any such outstanding Terminating Award that is subject to performance-vesting, unless otherwise provided in the individual grant notice and award agreement evidencing such award, such performance-vesting award will accelerate vesting at 100% of the target level.  For the avoidance of doubt, the benefits under this Section 4 are contingent on a Change in Control and do not require your Covered Termination or other termination of service. In addition, you may be eligible for benefits under this Section 4 in addition to benefits under Section 2 or Section 3 above, and in such case, you shall receive benefits under both sections, without duplication.
