These Standard Terms and Conditions apply to the Award of Restricted Stock Units granted pursuant to the Stem, Inc. 2021 Equity Incentive Plan (the “Plan”), which are evidenced by a Grant Notice or an action of the Committee that specifically refers to these Standard Terms and Conditions. In addition to these Standard Terms and Conditions, the Restricted Stock Units shall be subject to the terms of the Plan, which are incorporated into these Standard Terms and Conditions by this reference. Capitalized terms not otherwise defined herein shall have the meaning set forth in the Plan.

Stem, Inc. (the “Company”) has granted to the Participant named in the Grant Notice provided to said Participant herewith (the “Grant Notice”) an award of Restricted Stock Units (the “Award” or “RSUs”) specified in the Grant Notice, with each Restricted Stock Unit representing the right to receive one share of Common Stock. The Award is subject to the conditions set forth in the Grant Notice, these Standard Terms and Conditions and the Plan. For purposes of these Standard Terms and Conditions and the Grant Notice, any reference to the Company shall include a reference to any Subsidiary.

(a)The Award shall not be vested as of the Grant Date set forth in the Grant Notice and shall be forfeitable unless and until otherwise vested pursuant to the terms of the Grant Notice and these Standard Terms and Conditions. After the Grant Date, subject to termination or acceleration as provided in these Standard Terms and Conditions and the Plan, the Award shall become vested as described in the Grant Notice with respect to that number of Restricted Stock Units as set forth in the Grant Notice. Restricted Stock Units that have vested and are no longer subject to forfeiture are referred to herein as “Vested RSUs.” Restricted Stock Units awarded hereunder that are not vested and remain subject to forfeiture are referred to herein as “Unvested RSUs.”

(b)As soon as administratively practicable following the vesting of the RSUs pursuant to the Grant Notice and this Section 2, but in no event later than 30 days after each vesting date, the Company shall deliver to the Participant a number of shares of Common Stock equal to the number of RSUs that vested on such date.

(c)Upon Participant’s termination of Continuous Service for any reason, any then Unvested RSUs held by the Participant shall be forfeited and canceled as of the date of the Participant’s termination of Continuous Service.

(a)Participant shall not be, nor have any of the rights or privileges of, a stockholder of the Company in respect of any RSUs unless and until shares of Common Stock settled for such RSUs shall have been issued by the Company to Participant (as evidenced by the appropriate entry on the books and records of the Company or of a duly authorized transfer agent of the Company).

(b)Notwithstanding the foregoing, from and after the Grant Date and until the earlier of (i) the Participant’s receipt of Common Stock upon settlement of the RSUs and (ii) the time when the Participant’s right to receive Common Stock upon settlement of the RSUs is forfeited, the Participant shall be entitled, as a Dividend equivalent, to a number of additional whole RSUs on the date that the Company pays a cash dividend (if any) to holders of Common Stock generally. Such Dividend equivalent shall be determined by dividing (i) the product of (A) the dollar amount of the cash dividend paid per share of Common Stock on such date and (B) the total number of RSUs (including dividend equivalents paid thereon) previously credited to the Participant as of such date, by (ii) the Fair Market Value per share of Common Stock on such date. Such Dividend equivalents (if any) shall be subject to the same terms and conditions and shall be settled or forfeited in the same manner and at the same time as the RSUs to which the Dividend equivalents were credited.

The Company may impose such restrictions, conditions or limitations as it determines appropriate as to the timing and manner of any resales by the Participant or other subsequent transfers by the Participant of any shares of Common Stock issued pursuant to Vested RSUs, including (a) restrictions under an insider trading policy, (b) restrictions designed to delay and/or coordinate the timing and manner of sales by Participant and other holders and (c) restrictions as to the use of a specified brokerage firm for such resales or other transfers.

Participant acknowledges and agrees that Participant shall be solely responsible for satisfying any and all national, state, local or other tax withholding obligation relating to the RSUs. Unless the Participant elects to instead tender a cash payment in satisfaction of such tax withholding obligations in the manner prescribed by the Company, the Participant acknowledges and agrees that the Company, or any brokerage firm deemed acceptable by the Company, shall generate enough cash proceeds to satisfy such tax withholding obligations by selling on the Participant’s behalf a sufficient number of shares of Common Stock from shares of Common Stock otherwise issuable to the Participant upon the vesting and settlement of the RSUs. Such shares of Common Stock will be sold on the day such tax withholding obligations arise or, if such day is not a trading day, the next following trading day. The Participant shall be responsible for all broker’s fees and other costs of sale. The Participant acknowledges that the Company or its designee is under no obligation to arrange for such sale at any particular price, and that the proceeds of any such sale may not be sufficient to satisfy the Participant’s tax withholding obligations. Accordingly, the Participant agrees to pay to the Company as soon as

practicable, including through additional payroll withholding, any amount of the tax withholding obligations that are not satisfied by the sale of shares of Common Stock described above.

The Participant understands, acknowledges and agrees that, except as otherwise provided in the Plan or as permitted by the Committee, the Award may not be sold, assigned, transferred, pledged or otherwise directly or indirectly encumbered or disposed of other than by will or the laws of descent and distribution.

The Grant Notice, these Standard Terms and Conditions and the Plan constitute the entire understanding between the Participant and the Company regarding the Award. Any prior agreements, commitments or negotiations concerning the Award are superseded.

Neither the Participant (individually or as a member of a group) nor any beneficiary or other person claiming under or through the Participant shall have any right, title, interest, or privilege in or to any shares of Common Stock allocated or reserved for the purpose of the Plan or subject to the Grant Notice or these Standard Terms and Conditions except as to such shares of Common Stock, if any, as shall have been issued to such person in connection with the Award. Nothing in the Plan, in the Grant Notice, these Standard Terms and Conditions or any other instrument executed pursuant to the Plan shall confer upon the Participant any right to continue to serve the Company or an Affiliate in the capacity in effect at the time this Award was granted or any other capacity or will affect the right of the Company or an Affiliate to terminate the service of the Participant.

(a)In the event that any provision of these Standard Terms and Conditions is declared to be illegal, invalid or otherwise unenforceable by a court of competent jurisdiction, such provision shall be reformed, if possible, to the extent necessary to render it legal, valid and enforceable, or otherwise deleted, and the remainder of these Standard Terms and Conditions shall not be affected except to the extent necessary to reform or delete such illegal, invalid or unenforceable provision.

(b)The headings preceding the text of the sections hereof are inserted solely for convenience of reference, and shall not constitute a part of these Standard Terms and Conditions, nor shall they affect its meaning, construction or effect. Words in the masculine gender shall include the feminine gender, and where appropriate, the plural shall include the singular and the singular shall include the plural. The use herein of the word “including” following any general statement, term or matter shall not be construed to limit such statement, term or matter to the specific items or matters set forth immediately following such word or to

References herein to any agreement, instrument or other document means such agreement, instrument or other document as amended, supplemented and modified from time to time to the extent permitted by the provisions thereof and not prohibited by the Plan or these Standard Terms and Conditions.

(c)These Standard Terms and Conditions shall inure to the benefit of and be binding upon the parties hereto and their respective permitted heirs, beneficiaries, successors and assigns.

(d)These Standard Terms and Conditions shall be construed in accordance with and governed by the laws of the State of Delaware, without regard to principles of conflicts of law.
