 Exhibit 10.12 

EMPLOYMENT AGREEMENT 

This Employment Agreement (the “Agreement”) is made and entered into effective as of March 3, 2015 (the “Effective
Date”), by and between Yang Song (the “Employee”) and ESS Tech, Inc. (the “Company”). 
 In consideration of the
mutual covenants herein contained, the continuing employment of the Employee by the Company, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows: 

1. Duties and Scope of Employment. The Company shall employ Employee in the position of Chief Technology Officer. Employee will render
such business and professional services in the performance of her duties, consistent with Employee’s position within the Company, as shall reasonably be assigned to him by the Company’s Board of Directors (the “Board”). Only the
Board shall have the right to revise such responsibilities from time to time, as the Board deems necessary or appropriate. 
 2.
Obligations. While employed hereunder, Employee will perform her duties faithfully and to the best of her ability. Employee agrees not to actively engage in any other employment, occupation or consulting activity for any direct or indirect
remuneration without the prior approval of the Board; provided, however, that Employee may engage in non-competitive business or charitable activities so long as such activities do not materially interfere
with Employee’s responsibilities to the Company. Outside board seats shall be subject to the prior approval of the Board. 
 3.
RESERVED. 
 4. Employment Term. Employee’s employment with the Company pursuant to this Agreement shall commence on the
Effective Date and shall continue on an “at-will” basis until terminated pursuant to Section 6 of this Agreement, and subject to the severance provisions therein. 

5. Compensation and Benefits. 

(a) Base Compensation. The Company shall pay Employee as compensation for Employee’s services hereunder an annual base salary of
$125,000.00. Such salary shall be subject to applicable tax withholding and shall be paid periodically in accordance with normal Company payroll practices. The base salary shall be subject to annual review by the Board but in no event shall be less
than $125,000.00. 
 (b) Incentive Bonus. Employee will be eligible to earn a target bonus for each calendar year in which she is
employed, commencing with calendar year 2015, based on the achievement of certain Company performance goals, as determined by the Board, and certain Employee performance goals, as mutually agreed to by Employee and the Board. The target bonus and
performance goals for 2015 shall be established within 












 sixty (60) days of the Effective Date and, with respect to future years, within sixty (60) days of
the start of each calendar year. If earned, the initial target bonus for 2015 shall be paid no later than thirty (30) days of the first anniversary of the Effective Date. Each subsequent bonus shall be paid in the immediately following calendar
year, no later than March 15th of such year. 
 (c) Benefits. Employee shall be eligible to participate in the employee benefit plans
which are available or which become available to other employees of the Company, with the adoption or maintenance of such plans to be in the discretion of the Company, subject in each case to the generally applicable terms and conditions of the plan
or program in question and to the determination of any committee administering such plan or program. Such benefits will include participation in any Company medical, life, disability, and/or retirement plans, and any supplemental plans available to
senior executives of the Company from time to time. Employee will also be entitled to paid vacation of three (3) weeks per year, with the timing and duration of specific vacations mutually and reasonably agreed to by the parties hereto. The
Company reserves the right to change or terminate its employee benefit plans and programs at any time, not including incentive bonuses established pursuant to Section 5(b) of this Agreement, severance or death benefits established pursuant to
Section 6 of this Agreement, any other bonus or severance arrangements to which Employee might otherwise be entitled, or any outstanding equity rights or awards granted to Employee. 

(d) Expenses. The Company will reimburse Employee for reasonable business expenses incurred by Employee in the furtherance of or in
connection with the performance of Employee’s duties hereunder, in accordance with the Company’s expense reimbursement policy as in effect from time to time. 

6. Termination of Employment. 

(a) Termination by Company for Cause; Voluntary Termination. In the event Employee’s employment with the Company is terminated for
“Cause” (as defined herein) by the Company or voluntarily by Employee (i) the Company shall pay Employee any unpaid base salary due for periods prior to the date of termination of employment (“Termination Date”); (ii) the
Company shall pay Employee all of Employee’s accrued and unused vacation through the Termination Date; and (iii) following submission of proper expense reports by Employee, the Company shall reimburse Employee for all expenses reasonably and
necessarily incurred by Employee in connection with the business of the Company prior to termination. These payments shall be made promptly upon termination and within the period of time mandated by applicable law. 

(b) Termination by Company without Cause. The Company may terminate Employee’s employment without Cause upon thirty (30) days
written notice to Employee. If Employee’s employment with the Company terminates other than voluntarily or for Cause, and Employee signs and does not revoke a Release, then Employee shall be entitled to: 

  
 2 













 (i) Receive continuing payments of severance pay (less applicable withholding taxes) at a
rate equal to her base salary and 100% of any earned bonus, as then in effect, for a period of six (6) months from the date of such termination, plus an additional one month for each year the Company has positive cash flow, to be paid
periodically in accordance with the Company’s normal payroll policies. 
 (ii) The same level of benefits coverage as in effect for the
Employee on the day immediately preceding the day of the Employee’s termination of employment. The Company shall continue to provide Employee such benefits until the earlier of (i) Employee’s reemployment with benefits of equal or
greater value or (ii) the end of the period for which severance pay is due pursuant to Section 6(b)(i) above. 
 (c) Death.
In the event of Employee’s death while employed hereunder, Employee’s beneficiary (or such other person(s) specified by will or the laws of descent and distribution) will receive (i) any unpaid base salary or unused vacation earned
for periods prior to Employee’s death, (ii) Company-paid benefits as specified in Section 6(b)(ii) above for ninety (90) days from Employee’s death, and (iii) the target bonus to which Employee would have been entitled
pursuant to the terms of Section 5(b) prorated to the date of Employee’s death. 
 (d) Termination by Employee for Good
Reason. If Employee terminates employment with the Company for “Good Reason” (as defined herein) within 90 days of a Good Reason event, and Employee signs and does not revoke a Release, then, subject to Employee’s compliance with
Section 9, Employee shall be entitled to the same benefits that she would receive in Section 6(b) above. 
 7. Change of Control
Benefits. If Employee (i) is terminated other than for Cause by the Company within 90 days prior to a “Change of Control” (as defined herein) or in connection with a Change of Control or (ii) is terminated other than for
Cause by the Company (or its successor corporation) or resigns for Good Reason within twelve (12) months following a Change of Control, and Employee signs and does not revoke a Release, then Employee shall be entitled to the following benefits: 

(a) Severance pay (less applicable withholding taxes) equal to her base salary rate, as then in effect, for a period of twelve
(12) months, to be paid in a single lump sum payment within sixty (60) days of the Change in Control. 
 (b) A single lump sum
payment (less applicable withholding taxes) equal to 100% of her target bonus as then in effect, payable within sixty (60) days of the Change in Control. 

For the avoidance of any doubt, payment of the benefits described in this Section 7 are instead of those described in Section 6.
Thus, if Employee is entitled to payment of the benefits under this Section 7, she shall not be entitled to the benefits described in Section 6. 

  
 3 













 Notwithstanding anything in this Agreement to the contrary, in the event that the benefits
provided for in this Section 7 (i) constitute “parachute payments” within the meaning of Section 280G of the Code, and (ii) would be subject to the excise tax imposed by Section 4999 of the Code (the “Excise
Tax”), then Employee’s benefits otherwise payable under this Section 7 shall be reduced by the minimum extent necessary such that no portion of such benefits would be subject to the Excise Tax. Unless the Company and Employee
otherwise agree in writing, any determination required under this Section 7 shall be made in writing by the Company’s independent public accountants (the “Accountants”), whose determination shall be conclusive and binding upon
Employee and the Company for all purposes. For purposes of making the calculations required by this Section 7, the Accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith
interpretations concerning the application of Section 280G and 4999 of the Code. The Company and Employee shall furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make a determination
under this Section 7. The Company shall bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this Section 7. 

8. No Impediment to Agreement. Employee hereby represents to the Company that Employee is not, as of the date hereof, and will not be
during Employee’s employment with the Company, employed under contract, oral or written, by any other person, firm or entity, and is not and will not be bound by the provisions of any restrictive covenant or confidentiality agreement which
would constitute an impediment to, or restriction upon, Employee’s ability to enter this Agreement and to perform the duties of Employee’s employment. 

9. Dispute Resolution. 

(a) Mediation. In the event of any dispute or claim arising out of, in connection with, or related to this Agreement, the parties shall
first meet and confer in good faith to fairly and equitably resolve the dispute. Such meeting shall occur within seven days of the date of notice implementing this dispute resolution process. If the parties cannot resolve the issue within 10 days
following such meeting, then they shall mediate the matter within 30 days after their meeting, under the auspices of Arbitration Service of Portland (“ASP”), or if that entity fails or declines to serve, such other similar service or
organization as agreed by the parties to this Agreement. 
 (b) Arbitration. Should the parties be unable to resolve any such dispute
through such mediation, they agree that binding arbitration shall be the exclusive remedy for any such claim or dispute. Any arbitration shall be conducted through ASP in Portland, Oregon, using a single arbitrator agreed upon by the parties, or if
the parties are unable to agree on an arbitrator, selected by the parties alternatively striking names off a list of seven arbitrators provided by ASP. Such arbitration shall be conducted under the employment arbitration rules of ASP. Advance costs
of the arbitration shall be divided equally between the parties. If the arbitrator finds, based on all the facts and circumstances, that the conduct of or the claims made by a party were unreasonable or 

  
 4 













 substantially without merit, the prevailing party shall be entitled to recover its reasonable
attorney’s fees and expenses (including expert witness fees) incurred in connection with the arbitration and any subsequent litigation, together with the costs of the arbitration, from the party asserting unreasonable or meritless claims, in
addition to all other remedies provided in law or in equity. Judgment on the arbitration award may be entered by any court of competent jurisdiction. Should any party to this Agreement institute any legal action or administrative proceeding against
the other with respect to any Claim or arbitrable dispute related to this Agreement without first engaging in binding arbitration as provided herein, the responding party will be entitled to recover from the initiating party all damages, costs,
expenses, and attorneys fees incurred as a result of that breach.
