 Ladies and Gentlemen: 

Stem, Inc., a Delaware corporation (the “Company”), proposes to sell to the several initial purchasers named in Schedule I
hereto (the “Initial Purchasers”), for whom you (the “Representatives”) are acting as representatives, $400,000,000 principal amount of the Company’s 0.5% Convertible Notes due 2028 (the “Firm
Securities”). The Company also proposes to grant to the Initial Purchasers an option to purchase up to $60,000,000 additional principal amount of such Notes for the sole purpose of covering sales of Notes in excess of the principal amount
of Firm Securities (the “Option Securities”; the Option Securities, together with the Firm Securities, being hereinafter called the “Securities”). The Securities are convertible into cash up to the aggregate
principal amount of such Securities and cash, shares (the “Underlying Securities”) of common stock of the Company, par value $0.0001 per share (the “Common Stock”), or a combination of cash and Underlying
Securities, at the Company’s election, in respect of the remainder, if any, of the Company’s conversion obligation in excess of the aggregate principal amount of such Securities being converted, at the conversion price set forth herein.
The Securities are to be issued under an indenture (the “Indenture”), to be dated as of the Closing Date (as defined below), between the Company and U.S. Bank National Association, as trustee (the “Trustee”). To the
extent there are no additional initial purchasers listed on Schedule I other than you, the term Representatives as used herein shall mean you as the Initial Purchasers, and the terms Representatives and Initial Purchasers shall mean either the
singular or plural as the context requires. The use of the neuter in this agreement (the “Agreement”) shall include the feminine and masculine wherever appropriate.

 In connection with the offering of the Firm Securities, the Company is separately entering
into privately negotiated capped call transactions with one or more option counterparties, which may include one or more of the Initial Purchasers and/or their affiliates (each, a “Capped Call Counterparty”), in each case pursuant
to a capped call confirmation (a “Base Capped Call Confirmation”), each dated the date hereof, and in connection with the issuance of any Option Securities, the Company and each Capped Call Counterparty may enter into additional
capped call transactions, in each case pursuant to an additional capped call confirmation (an “Additional Capped Call Confirmation”), each to be dated the date on which the option granted to the Initial Purchasers to purchase such
Option Securities pursuant to Section 2 hereof is exercised (the Additional Capped Call Confirmations, together with the Base Capped Call Confirmations, the “Capped Call Confirmations”). 

The sale of the Securities to the Initial Purchasers will be made without registration of the Securities or the Underlying Securities under
the Securities Act (as defined below) in reliance upon exemptions from the registration requirements of the Securities Act. 
 In connection
with the sale of the Securities, the Company has prepared a preliminary offering memorandum, dated November 16, 2021 (as amended or supplemented at the date thereof, including any information incorporated by reference therein, the
“Preliminary Memorandum”), and a final offering memorandum, dated November 17, 2021 (as amended or supplemented at the Execution Time (as defined below), including any information incorporated by reference therein, the
“Final Memorandum”). Each of the Preliminary Memorandum and the Final Memorandum sets forth certain information concerning the Company, the Securities and the Underlying Securities. The Company hereby confirms that it has authorized
the use of the Disclosure Package (as defined below), the Preliminary Memorandum and the Final Memorandum, and any amendment or supplement thereto, in connection with the offer and sale of the Securities by the Initial Purchasers. Unless stated to
the contrary, any references herein to the terms “amend”, “amendment” or “supplement” with respect to the Final Memorandum shall be deemed to refer to and include any information filed under the Exchange Act (as defined

 Any certificate signed
by any officer of the Company and delivered to the Representatives or counsel for the Initial Purchasers in connection with the offering of the Securities shall be deemed a representation and warranty by the Company, as to matters covered thereby,
to each Initial Purchaser. 
 2. Purchase and Sale. 

(a) Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Company agrees to sell to
each Initial Purchaser, and each Initial Purchaser agrees, severally and not jointly, to purchase from the Company, at a purchase price of 97.00% of the principal amount thereof, plus accrued interest, if any, from November 22, 2021 to the
Closing Date, the principal amount of Firm Securities set forth opposite such Initial Purchaser’s name in Schedule I hereto. 
 (b)
Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Company hereby grants an option to the several Initial Purchasers to purchase, severally and not jointly, the Option Securities at the
same purchase price per share as the Initial Purchasers shall pay for the Firm Securities, plus accrued interest, if any, from November 22, 2021 to the settlement date for the Option Securities, provided that the settlement date for any
purchase of Option Securities must occur during the thirteen-day period from, and including, the Closing Date (such period, the “Exercise Period”). The option may be exercised upon written or
telegraphic notice by the Representatives to the Company setting forth the principal amount of Option Securities as to which the several Initial Purchasers are exercising the option and the settlement date. Delivery of the Option Securities, and
payment therefor, shall be made as provided in Section 3 hereof. The principal amount of Option Securities to be purchased by each Initial Purchaser shall be the same percentage of the total principal amount of Option Securities to be purchased
by the several Initial Purchasers as such Initial Purchaser is purchasing of the Firm Securities, subject to such adjustments as you in your absolute discretion shall make to eliminate any fractional Securities. 

  
 11 












 3. Delivery and Payment. Delivery of and payment for the Firm Securities and the
Option Securities (if the option provided for in Section 2(b) hereof shall have been exercised on or before the second Business Day (as defined below) immediately preceding the Closing Date) shall be made at 10:00 AM, New York City time, on
November 22, 2021, or at such time on such later date not more than three Business Days after the foregoing date as the Representatives shall designate, which date and time may be postponed by agreement between the Representatives and the
Company or as provided in Section 9 hereof (such date and time of delivery and payment for the Securities being herein called the “Closing Date”). Delivery of the Securities shall be made to the Representatives for the
respective accounts of the several Initial Purchasers with any transfer taxes payable in connection therewith duly paid by the Company, against payment by the several Initial Purchasers through the Representatives of the purchase price thereof to or
upon the order of the Company by wire transfer payable in same-day funds to an account specified by the Company. Delivery of the Firm Securities and the Option Securities shall be made through the facilities
of The Depository Trust Company, unless the Representatives shall otherwise instruct. 
 If the option provided for in Section 2(b)
hereof is exercised after the second Business Day immediately preceding the Closing Date, the Company will deliver the Option Securities (at the expense of the Company) to the Representatives, at 1585 Broadway, New York, New York 10036, on the date
specified by the Representatives (which shall be within three Business Days after exercise of said option and within the Exercise Period) for the respective accounts of the several Initial Purchasers, against payment by the several Initial
Purchasers through the Representatives of the purchase price thereof to or upon the order of the Company by wire transfer payable in same-day funds to an account specified by the Company. If settlement for the
Option Securities occurs after the Closing Date, the Company will deliver to the Representatives on the settlement date for the Option Securities, and the obligation of the Initial Purchasers to purchase the Option Securities shall be conditioned
upon receipt of, supplemental opinions, certificates and letters confirming as of such date the opinions, certificates and letters delivered on the Closing Date pursuant to Section 6 hereof. 

4. Offering by Initial Purchasers. (a) Each Initial Purchaser acknowledges that the Securities and the Underlying Securities have
not been and will not be registered under the Securities Act and may not be offered or sold except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act. 

(b) Each Initial Purchaser, severally and not jointly, represents and warrants to and agrees with the Company that: 

(i) it has not offered or sold, and will not offer or sell, any Securities as part of their distribution at any time except in
the case of sales to those it reasonably believes to be “qualified institutional buyers” as permitted by in Rule 144A under the Securities Act; 

(ii) neither it nor any person acting on its behalf has made or will make offers or sales of the Securities by means of a
General Solicitation, other than any General Solicitation in respect of which the Representatives have given their prior written consent; provided that the prior written consent of the Representatives shall be deemed to have been given in respect of
the General Solicitation included in Schedule III hereto; 
 (iii) it has taken or will take reasonable steps to ensure that
each purchaser of Securities is aware that such sale may be made in reliance on Rule 144A; and 
 (iv) it is an
“accredited investor” (as defined in Rule 501(a) of Regulation D). 
 5. Agreements. The Company agrees with the several
Initial Purchasers that: 
 (a) The Company will furnish to each Initial Purchaser and to counsel for the Initial Purchasers, without charge,
during the period referred to in Section 5(c) below, as many copies of the materials contained in the Disclosure Package and the Final Memorandum and any amendments and supplements thereto as they may reasonably request. 

  
 12 












 (b) The Company will not amend or supplement the Disclosure Package or the Final Memorandum,
other than by filing documents under the Exchange Act that are incorporated by reference therein, without the prior written consent of the Representatives; provided, however, that prior to the completion of the distribution of the Securities by the
Initial Purchasers (as determined by the Initial Purchasers), the Company will not file any document under the Exchange Act that is incorporated by reference in the Disclosure Package or the Final Memorandum unless, prior to such proposed filing,
the Company has furnished the Representatives with a copy of such document for their review and the Representatives have not reasonably objected to the filing of such document. The Company will promptly advise the Representatives when any document
filed under the Exchange Act that is incorporated by reference in the Disclosure Package or the Final Memorandum shall have been filed with the SEC (as defined below). 

(c) If at any time prior to the completion of the sale of the Securities by the Initial Purchasers (as determined by the Representatives), any
event occurs as a result of which the Disclosure Package, any General Solicitation, or the Final Memorandum, as then amended or supplemented, would include any untrue statement of a material fact or omit to state any material fact necessary to make
the statements therein, in the light of the circumstances under which they were made or the circumstances then prevailing, not misleading, or if it should be necessary to amend or supplement the Disclosure Package or the Final Memorandum to comply
with applicable law, the Company will promptly (i) notify the Representatives of any such event; (ii) subject to the requirements of Section 5(b), prepare an amendment or supplement that will correct such statement or omission or
effect such compliance; and (iii) supply any supplemented or amended Disclosure Package or Final Memorandum to the several Initial Purchasers and counsel for the Initial Purchasers without charge in such quantities as they may reasonably
request. 
 (d) Without the prior written consent of the Representatives, which shall not be unreasonably withheld, the Company has not given
and will not give to any prospective purchaser of the Securities any written information concerning the offering of the Securities other than materials contained in the Disclosure Package, the Final Memorandum or any other offering materials
prepared by or with the prior written consent of the Representatives. 
 (e) The Company will arrange, if necessary, for the qualification of
the Securities for sale by the Initial Purchasers under the laws of such jurisdictions as the Representatives reasonably may designate and will maintain such qualifications in effect so long as required for the distribution of the Securities;
provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the
offering or sale of the Securities, in any jurisdiction where it is not now so subject. The Company will promptly advise the Representatives of the receipt by the Company of any notification with respect to the suspension of the qualification of the
Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose. 
 (f) None of the Company, its
affiliates, or any person acting on its or their behalf (other than the Initial Purchasers, as to which no comment is made) will, directly or indirectly, make offers or sales of any security, or solicit offers to buy any security, under
circumstances that would require the registration of the Securities or the Underlying Securities under the Securities Act. 
 (g) None of the
Company, its affiliates, or any person acting on its or their behalf (other than the Initial Purchasers, as to which no comment is made) will engage in any form of general solicitation or general advertising General Solicitation, other than any
General Solicitation in respect of which the Representatives have given their prior written consent; provided that the prior written consent of the Representatives shall be deemed to have been given in respect of the General Solicitation included in
Schedule III hereto in connection with any offer or sale of the Securities. 
 (h) For so long as any of the Securities or the Common Stock
issuable upon the conversion thereof are “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, the Company will, during any period in which it is not subject to and in compliance with Section 13 or
15(d) of the Exchange Act, provide to each holder of such restricted securities and to each prospective purchaser (as designated by such holder) of such restricted securities, upon the request of such holder or prospective purchaser, any
information required to be provided by Rule 144A(d)(4) under the Securities Act. This covenant is intended to be for the benefit of the holders, and the prospective purchasers designated by such holders, from time to time of such restricted
securities.

 (l)
The Company will not for a period of 45 days following the Execution Time, without the prior written consent of the Representatives, directly or indirectly, (i) offer, sell, contract to sell, pledge, grant any option to purchase, hedge, make
any short sale or otherwise transfer or dispose of, directly or indirectly, or file with or confidentially submit to the SEC a registration statement under the Securities Act relating to, the Securities, Common Stock or any securities of the Company

part, any of the economic consequences of ownership of the Securities, Common Stock or any such other securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Securities, Common Stock or
such other securities, in cash or otherwise, or (iii) publicly disclose the intention to do any of the foregoing (such 45 day period, the “Restricted Period”), provided, however, that the foregoing restrictions
shall not apply to (A) the transactions contemplated hereby (including, for the avoidance of doubt, (x) the issuance of the Securities, (y) the issuance of any Underlying Securities issued upon conversion of such Securities and
(z) the entry into, and the exercise of the Company’s rights and performance of its obligations under, the Capped Call Confirmations), (B) the Common Stock to be sold pursuant to employee stock option plans existing on the date of this

agreement of the same duration and terms as provided in this section. 
 (m) The Company will not take, directly or indirectly (without
giving effect to activities by the Initial Purchasers), any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of

conditions: 

  
 15

counsel for the Company, to have furnished to the Representatives their opinion and negative assurance letter, dated the Closing Date and addressed to the Representatives, in a form reasonably satisfactory to the Representatives. 

(b) The Representatives shall have received from Latham & Watkins LLP, counsel for the Initial Purchasers, such opinion and negative
assurance letter, dated the Closing Date and addressed to the Representatives, with respect to the issuance and sale of the Securities, the Indenture, the Disclosure Package, the Final Memorandum (as amended or supplemented at the Closing Date) and
other related matters as the Representatives may reasonably require, and the Company shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters. 

(c) The Company shall have furnished to the Representatives a certificate of the Company, signed by the Chief Executive Officer and the Chief
Financial Officer of the Company, dated the Closing Date, to the effect that the signers of such certificate have carefully examined the Disclosure Package and the Final Memorandum and any amendment or supplement thereto, and this Agreement and
that: 
 (i) the representations and warranties of the Company in this Agreement are true and correct on and as of the
Closing Date with the same effect as if made on the Closing Date and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Closing Date; and 

(ii) since the date of the most recent financial statements included or incorporated by reference in the Disclosure Package and
the Final Memorandum (exclusive of any amendment or supplement thereto), there has been no material adverse change in the condition (financial or otherwise), prospects, earnings, business or properties of the Company and its subsidiaries, taken as a
whole, whether or not arising from transactions in the ordinary course of business. 
 (d) The Company shall have requested and caused
Deloitte & Touche LLP to have furnished to the Representatives, at the Execution Time and at the Closing Date, letters, dated respectively as of the Execution Time and as of the Closing Date, in form and substance satisfactory to the

Section 6 or (ii) any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), earnings, business or properties of the Company and its subsidiaries taken as a whole, whether or not
arising from transactions in the ordinary course of business, the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the Representatives, so material and adverse as to make it impractical or
inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto). 

(f) The Securities shall be eligible for clearance and settlement through The Depository Trust Company. 

(g) Prior to the Execution Time, the Company shall have furnished to the Representatives a letter substantially in the form of Exhibit A hereto

Purchasers’ Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Initial Purchasers set forth in Section 6 hereof is not satisfied, because of any
termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Initial
Purchasers, the Company will reimburse the Initial Purchasers severally through Morgan Stanley & Co. LLC on demand for all reasonably incurred and documented expenses (including reasonably incurred fees and disbursements of counsel for the
Initial Purchasers) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities. 
 8.
Indemnification and Contribution. 
 (a) The Company agrees to indemnify and hold harmless each Initial Purchaser, the directors,
officers, employees, affiliates and agents of each Initial Purchaser and each person who controls any Initial Purchaser within the meaning of either the Securities Act or the Exchange Act against any and all losses, claims, damages or liabilities,
joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other U.S. Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Memorandum, the Final Memorandum, any Issuer Written Information, any General
Solicitation, or any other written information used by or on behalf of the Company in connection with the offer or sale of the Securities, or in any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission
to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any reasonably incurred legal or other expenses
reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or
on behalf of any Initial Purchaser through the Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have. 

  
 17 












 (b) Each Initial Purchaser severally and not jointly agrees to indemnify and hold harmless
the Company, each of its directors, officers and each person who controls the Company within the meaning of either the Securities Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Initial Purchaser, but
only with reference to written information relating to such Initial Purchaser furnished to the Company by or on behalf of such Initial Purchaser through the Representatives specifically for inclusion in the documents referred to in the foregoing
indemnity. This indemnity agreement will be in addition to any liability which any Initial Purchaser may otherwise have. The Company acknowledges that the statements set forth (i) in the fourth sentence in the second paragraph under the heading
“Option to Purchase Additional Notes” under the caption “Plan of Distribution”, (ii) the first sentence in the first paragraph under the heading “Price Stabilization and Short Positions; Repurchase of Common Stock”
under the caption “Plan of Distribution” and (iii) the second paragraph under the heading “Price Stabilization and Short Positions; Repurchase of Common Stock” under the caption “Plan of Distribution” related to
stabilization and syndicate covering transactions, in the Preliminary Memorandum and the Final Memorandum constitute the only information furnished in writing by or on behalf of the several Initial Purchasers for inclusion in the Preliminary
Memorandum or the Final Memorandum or in any amendment or supplement thereto. 
 (c) Promptly after receipt by an indemnified party under
this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the
commencement thereof. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense (it being understood, however, that the indemnifying party shall not be liable for the
expenses of more than one separate counsel in addition to local counsel) to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and
expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying
party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonably incurred
fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants
in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are
different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after
notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent
of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether
or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such claim,
action, suit or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party. Notwithstanding the foregoing, if at any time an indemnified party shall
have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without
its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance
with such request prior to the date of such settlement. 
 (d) In the event that the indemnity provided in paragraph (a) or (b) of this
Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Initial Purchasers severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or
other expenses reasonably incurred in connection with investigating or defending the same) (collectively, “Losses”) to which the Company and one or more of the Initial Purchasers may be


  
 18 












 
subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Initial Purchasers on the other from the offering of the
Securities. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Initial Purchasers severally shall contribute in such proportion as is appropriate to reflect not only such relative
benefits but also the relative fault of the Company on the one hand and of the Initial Purchasers on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations.
Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Initial Purchasers shall be deemed to be equal to the total purchase
discounts and commissions, in each case as set forth on the cover page of the Final Memorandum. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information provided by the Company on the one hand or the Initial Purchasers on the other, the intent of the parties and their relative knowledge, access to information and
opportunity to correct or prevent such untrue statement or omission. The Company and the Initial Purchasers agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which
does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), in no event shall an Initial Purchaser be required to contribute any amount in excess of the amount by which the total
purchase discounts and commissions received by such Initial Purchaser with respect to the offering of the Securities exceeds the amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Initial Purchaser within the meaning of either the Securities Act or the Exchange Act and each
director, officer, employee, affiliate and agent of an Initial Purchaser shall have the same rights to contribution as such Initial Purchaser, and each person who controls the Company within the meaning of either the Securities Act or the Exchange
Act and each officer and director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d). 

9. Default by an Initial Purchaser. If any one or more Initial Purchasers shall fail to purchase and pay for any of the Securities
agreed to be purchased by such Initial Purchaser or Initial Purchasers hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Initial Purchasers shall be
obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate principal amount of Securities set forth opposite the names
of all the remaining Initial Purchasers) the Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Securities
which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule I hereto, the remaining Initial Purchasers shall have the right to
purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such non-defaulting Initial Purchasers do not purchase all the Securities, this Agreement will terminate without
liability to any non-defaulting Initial Purchaser or the Company. In the event of a default by any Initial Purchaser as set forth in this Section 9, the Closing Date shall be postponed for such period,
not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Final Memorandum or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any
defaulting Initial Purchaser of its liability, if any, to the Company and any non-defaulting Initial Purchaser for damages occasioned by its default hereunder. 

  
 19 












 10. Termination. This Agreement shall be subject to termination in the absolute
discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Securities, or the Option Securities, as the case may be, if at any time prior to such delivery and payment (i) trading in the
Company’s Common Stock shall have been suspended by the SEC or the New York Stock Exchange or trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on
such exchange, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities, (iii) there shall have occurred a material disruption in commercial banking or securities settlement or clearance services
or (iv) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the
sole judgment of the Representatives, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Disclosure Package or the Final Memorandum (exclusive of any amendment or supplement thereto). 

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other
statements of the Company or its officers and of the Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Initial Purchaser or the
Company or any of the officers, directors, employees, agents, affiliates or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall
survive the termination or cancellation of this Agreement. 
 12. Notices. All communications hereunder will be in writing and
effective only on receipt, and, if sent to the Representatives, will be mailed, delivered or telefaxed to (i) Morgan Stanley & Co. LLC, 1585 Broadway, 29th Floor, New York, New York 10036 Attention: Investment Banking Division (fax:

have any right or obligation hereunder. 
 14. No Fiduciary Duty. The Company hereby acknowledges that (a) the purchase and sale
of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the Initial Purchasers and any affiliate through which it may be acting, on
the other, (b) the Initial Purchasers are acting as principal and not as an agent or fiduciary of the Company, and (c) the Company’s engagement of the Initial Purchasers in connection with the offering and the process leading up to
the offering is as independent contractors and not in any other capacity. Furthermore, the Company agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether any of the Initial
Purchasers has advised or is currently advising the Company on related or other matters). The Company agrees that it will not claim that the Initial Purchasers have rendered advisory services of any nature or respect, or owe an agency, fiduciary or
similar duty to the Company, in connection with such transaction or the process leading thereto. 
 15. Recognition of the U.S. Special
Resolution Regimes. 
 (a) In the event that any Initial Purchaser that is a Covered Entity becomes subject to a proceeding under a U.S.
Special Resolution Regime, the transfer from such Initial Purchaser of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special
Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States. 

  
 20 












 (b) In the event that any Initial Purchaser that is a Covered Entity or a BHC Act Affiliate
of such Initial Purchaser becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Initial Purchaser are permitted to be exercised to no greater extent than such
Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

Regime” means each of (i) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (ii) Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

and the Initial Purchasers, or any of them, with respect to the subject matter hereof. 
 17. Applicable Law. This Agreement will be
governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York. 

18. Jurisdiction. The Company agrees that any suit, action or proceeding against the Company brought by any Initial Purchaser, the
directors, officers, employees, affiliates and agents of any Initial Purchaser, or by any person who controls any Initial Purchaser, arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in any State
or U.S. federal court in The City of New York and County of New York, and waives any objection which it may now or hereafter have to the laying of venue of any such proceeding, and irrevocably submits to the
non-exclusive jurisdiction of such courts in any suit, action or proceeding.

 As representatives of the initial
purchasers 
  

	 	Re:	 Stem, Inc. - Lock-Up Agreement 



Ladies and Gentlemen: 
 The undersigned
understands that you, as representatives (the “Representatives”), propose to enter into a purchase agreement (the “Purchase Agreement”) on behalf of the several initial purchasers named in Schedule I to such agreement
(collectively, the “Initial Purchasers”), with Stem, Inc., a Delaware corporation (the “Company”), providing for the offer of Convertible Senior Notes due 2028 (the “Notes”), which will be convertible into cash or a
combination of cash and common stock, par value $0.0001 per share (the “Common Stock”) of the Company. If more than one entity executes this agreement, this agreement shall constitute a separate agreement with respect to each such entity
as the “undersigned,” and the rights and obligations of each such entity hereunder shall be several and not joint. 
 In
consideration of the agreement by the Initial Purchasers to offer and sell the Notes, and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period beginning
from the date of this lock-up agreement (the “Lock-Up Agreement”) and continuing to and including the date 45 days after the date set forth on the final
offering memorandum used to sell the Notes (the “Lock-Up Period”), the undersigned shall not, and shall not cause or direct any of its affiliates to, (i) offer, sell, contract to sell, pledge,
grant any option to purchase, lend or otherwise dispose of any shares of Common Stock of the Company, or any options or warrants to purchase any shares of Common Stock of the Company, or any securities convertible into, exchangeable for or that
represent the right to receive shares of Common Stock of the Company (such options, warrants or other securities, collectively, “Derivative Instruments”), including without limitation any such shares or Derivative Instruments now owned or
hereafter acquired by the undersigned, (ii) engage in any hedging or other transaction or arrangement (including, without limitation, any short sale or the purchase or sale of, or entry into, any put or call option, or combination thereof,
forward, swap or any other derivative transaction or instrument, however described or defined) which is designed to or which reasonably could be expected 

  
 1 












 
to lead to or result in a sale, loan, pledge or other disposition (whether by the undersigned or someone other than the undersigned), or transfer of any of the economic consequences of ownership,
in whole or in part, directly or indirectly, of any shares of Common Stock of the Company or Derivative Instruments, whether any such transaction or arrangement (or instrument provided for thereunder) would be settled by delivery of Common Stock or
other securities, in cash or otherwise (any such sale, loan, pledge or other disposition, or transfer of economic consequences, a “Transfer”) or (iii) otherwise publicly announce any intention to engage in or cause any action or
activity described in clause (i) above or transaction or arrangement described in clause (ii) above. The undersigned represents and warrants that the undersigned is not, and has not caused or directed any of its affiliates to be or become,
currently a party to any agreement or arrangement that provides for, is designed to or which reasonably could be expected to lead to or result in any Transfer during the Lock-Up Period. For the avoidance of
doubt, the undersigned agrees that the foregoing provisions shall be equally applicable to any issuer-directed or other Notes the undersigned may purchase in the offering. 

If the undersigned is not a natural person, the undersigned represents and warrants that no single natural person, entity or “group”
(within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934 (the “Exchange Act”), as amended), other than a natural person, entity or “group” (as described above) that has executed a Lock-Up Agreement in substantially the same form as this Lock-Up Agreement, beneficially owns, directly or indirectly, 50% or more of the common equity interests, or 50% or
more of the voting power, in the undersigned. 
 Notwithstanding the foregoing, the undersigned may transfer the undersigned’s shares
of Common Stock of the Company: 
 (i) as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the
restrictions set forth herein; 
 (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned,
provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value; 

(iii) with the prior written consent of the Representatives on behalf of the Initial Purchasers; or 

(iv) pursuant to an existing trading plan established prior to the date of this Lock-Up Agreement pursuant to Rule 10b5-1 of the Exchange Act, provided that no filing by the undersigned under the Exchange Act, or other public announcement, shall be voluntarily made, and if the undersigned is required to file a report
under the Exchange Act related thereto during the Lock-Up Period, such report shall disclose that such transfer was pursuant to an existing trading plan established prior to the date of this Lock-Up Agreement pursuant to Rule 10b5-1 of the Exchange Act. 

Furthermore, notwithstanding the foregoing, the undersigned may enter into a written trading plan meeting the requirements of Rule 10b5-1 under the Exchange Act after the date of this Lock-Up Agreement relating to the sale of the undersigned’s shares of Common Stock, provided that (i) the
securities subject to such plan may not be transferred until after the expiration of the Lock-Up Period and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required
of or voluntarily made by or on behalf of the undersigned or the Company regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of Common Stock may be made under such plan
during the Lock-Up Period. 

  
 2 












 For purposes of this Lock-Up Agreement,
“immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin. In addition, notwithstanding the foregoing, if the undersigned is a corporation, the corporation may transfer the capital
stock of the Company to any wholly-owned subsidiary of such corporation; provided, however, that in any such case, it shall be a condition to the transfer that the transferee execute an agreement stating that the transferee is receiving and holding
such capital stock subject to the provisions of this Agreement and there shall be no further transfer of such capital stock except in accordance with this Agreement, and provided further that any such transfer shall not involve a disposition for
value. The undersigned now has, and, except as contemplated above, for the duration of this Lock-Up Agreement will have, good and marketable title to the undersigned’s shares of Common Stock of the
Company, free and clear of all liens, encumbrances, and claims whatsoever. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the
undersigned’s shares of Common Stock of the Company except in compliance with the foregoing restrictions. 
 The undersigned
acknowledges and agrees that none of the Initial Purchasers has made any recommendation or provided any investment or other advice to the undersigned with respect to this Lock-Up Agreement or the subject
matter hereof, and the undersigned has consulted its own legal, accounting, financial, regulatory, tax and other advisors with respect to this Lock-Up Agreement and the subject matter hereof to the extent the
undersigned has deemed appropriate. 
 The undersigned further acknowledges and agrees that, although the Initial Purchasers may provide
certain Regulation Best Interest and Form CRS disclosures or other related documentation to you in connection with the public offering, the Initial Purchasers are not making a recommendation to you to participate in the public offering, and nothing
set forth in such disclosures or documentation is intended to suggest that any Initial Purchasers is making such a recommendation. 
 This Lock-Up Agreement may be delivered via facsimile, electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com or www.echosign.com) or other
transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes. 

This Lock-Up Agreement and any transaction contemplated by this
Lock-Up Agreement and any claim, controversy or dispute arising under or related thereto shall be governed by and construed in accordance with the laws of the State of New York. 

  
 3 












 The undersigned understands that the Company and the Initial Purchasers are relying upon
this Lock-Up Agreement in proceeding toward consummation of the offering. The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be
binding upon the undersigned’s heirs, legal representatives, successors, and assigns.
