to be legally bound hereby, the parties hereby agree as follows:


 


1.                  
Lock-up Provisions.


 


(a)                Holder
hereby agrees not to (1) Transfer any Restricted Securities from and after the Closing and until the earlier of (x) the six
(6) month anniversary of the date of the Closing and (y) the date after the Closing on which STPK completes a liquidation,
merger, capital stock exchange, reorganization or other similar transaction that results in all of STPK’s stockholders
having the right to exchange their equity holdings in STPK for cash, securities or other property (clause (y), a
 “Liquidity Event”, and such period, the “Lock-up Period”), and (2) from and after the
execution of the Merger Agreement and until the end of the Lock-Up Period, directly or indirectly, engage in any short sales
or other hedging or derivative transactions in respect of STPK Common Shares or STPK Warrants; provided that the
foregoing restrictions shall not apply to the Transfer of any or all of the Restricted Securities owned by Holder made in
respect of a Permitted Transfer (as defined below); provided, further, that in any of case of a Permitted
Transfer, it shall be a condition to such Transfer that the transferee executes and delivers to STPK and the Company an
agreement, in substantially the same form of this Agreement, stating that the transferee is receiving and holding the
Restricted Securities subject to the provisions of this Agreement applicable to Holder, and there shall be no further
Transfer of such Restricted Securities except in accordance with this Agreement. As used herein,
 “Transfer” shall mean (i) the sale of, offer to sell, contract or agreement to sell, hypothecate, pledge,
grant of any option to purchase or otherwise dispose of or agreement to dispose of, directly or indirectly, or establishment
or increase of a put equivalent position or liquidation with respect to or decrease of a call equivalent position within the
meaning of Section 16 of the Exchange Act, and the rules and regulations of the SEC promulgated thereunder with respect to,
any security, (ii) entry into any swap or other arrangement that transfers to another, in whole or in part, any of the
economic consequences of ownership of any security, whether any such transaction is to be settled by delivery of such
securities, in cash or otherwise, or (iii) public announcement of any intention to effect any transaction specified in
clause (i) or (ii). As used in this Agreement, the term “Permitted Transfer” shall mean a Transfer made:
(A) in the case of Holder being an individual, by gift to a member of one of the individual’s immediate family, an
estate planning vehicle or to a trust, the beneficiary of which is a member of the individual’s immediate family, an
affiliate of such person or to a charitable organization; (B) in the case of Holder being an individual, by virtue of laws of
descent and distribution upon death of Holder; (C) in the case of Holder being an individual, pursuant to a qualified
domestic relations order; (D) by pro rata distributions from Holder to its members, partners, or shareholders pursuant to the
Holder’s organizational documents; (E) by virtue of applicable law or the Holder’s organizational documents upon
liquidation or dissolution of Holder; (F) to STPK for no value for cancellation in connection with the consummation of a
Liquidity Event; (G) in the event of STPK’s liquidation prior to the completion of a Liquidity Event; (H) in the event
of completion of a liquidation, merger, capital stock exchange, reorganization or other similar transaction which results in
all of the STPK’s holders of STPK Common Shares having the right to exchange their STPK Common Shares for cash,
securities or other property subsequent to the completion of a Liquidity Event; or (I) to any employees, officers, directors
or members of the Holder or any affiliates of the Holder.

(b)               
If any Transfer is made or attempted contrary to the provisions of this Agreement, such purported Transfer shall be null
and void ab initio, and STPK shall refuse to recognize any such purported transferee of the Restricted Securities as one of its
equity holders for any purpose. In order to enforce this Section 1, STPK may impose stop-transfer instructions with
respect to the Restricted Securities of Holder (and Permitted Transferees and assigns thereof) until the end of the Lock-up Period.


 


(c)               
During the Lock-up Period, each certificate evidencing any Restricted Securities shall be stamped or otherwise imprinted
with a legend in substantially the following form, in addition to any other applicable legends:


 


“THE SECURITIES REPRESENTED
BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER SET FORTH IN A LOCK-UP AGREEMENT, DATED AS OF NOVEMBER [●], 2020,
BY AND AMONG THE ISSUER OF SUCH SECURITIES (THE “ISSUER”), THE ISSUER’S SECURITY HOLDER NAMED THEREIN
AND CERTAIN OTHER PARTIES NAMED THEREIN, AS AMENDED. A COPY OF SUCH LOCK-UP AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE ISSUER
TO THE HOLDER HEREOF UPON WRITTEN REQUEST.”


 


(d)                For
the avoidance of any doubt, (i) Holder shall retain all of its rights as a stockholder of STPK during the Lock-up Period,
including the right to vote, and to receive any dividends and distributions in respect of, any Restricted Securities, and
(ii) the restrictions contained in clause (1) of Section 1(a) shall not apply to any STPK Common Shares or other
securities of STPK acquired by Holder in open market transactions or in any public or private capital raising transactions of
STPK or otherwise to any STPK Common Shares (or other securities of STPK) other than the Restricted Securities.1

        Note to Stem: The short sale, etc., restrictions in clause (2) need to
apply to all common stock and warrants of STPK.

2.                  
Miscellaneous.


 


(a)               
Termination of Merger Agreement. Notwithstanding anything to the contrary contained herein, in the event that the
Merger Agreement is terminated in accordance with its terms prior to the Closing, this Agreement and all rights and obligations
of the parties hereunder shall automatically terminate and be of no further force or effect; provided that, such termination
shall not affect any Liability on the part of any party for (i) a material breach of any covenant or agreement set forth in this
Agreement prior to such termination or (ii) Fraud.


 


(b)               
Binding Effect; Assignment. This Agreement and all of the provisions hereof shall be binding upon and inure to the
benefit of the parties hereto and their respective permitted successors and assigns. This Agreement and all obligations of Holder
are personal to Holder and may not be transferred or delegated by Holder at any time without the prior written consent of STPK,
the Company and Sponsor. Each of STPK and the Company may freely assign any or all of its rights under this Agreement, in whole
or in part, to any successor entity (whether by merger, consolidation, equity sale, asset sale or otherwise) without obtaining
the consent or approval of Holder.


 


(c)               
Third Parties. Nothing contained in this Agreement or in any instrument or document executed by any party in connection
with the transactions contemplated hereby shall create any rights in, or be deemed to have been executed for the benefit of, any
person or entity that is not a party hereto or thereto or a successor or permitted assign of such a party; provided, that
Star Peak Sponsor, LLC, a Delaware limited liability company (“Sponsor”), shall be an express third party beneficiary
of this Agreement and shall have the right to enforce the terms of this Agreement directly against Holder as if Sponsor were an
original party hereto.


 


(d)               
Governing Law; Jurisdiction; Waiver of Jury Trial; Remedies. This Agreement and all related Proceedings shall be
governed by and construed in accordance with the internal Laws of the State of Delaware, without giving effect to any choice of
law or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application
of the Law of any jurisdiction other than the State of Delaware. THE PARTIES HERETO EACH HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED
BY LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION (I) ARISING UNDER THIS AGREEMENT OR (II) IN
ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS AGREEMENT OR ANY OF THE
TRANSACTIONS RELATED HERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY, OR
OTHERWISE. THE PARTIES HERETO EACH HEREBY AGREE AND CONSENT THAT ANY SUCH CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION SHALL BE DECIDED
BY COURT TRIAL WITHOUT A JURY AND THAT THE PARTIES HERETO MAY FILE AN ORIGINAL COUNTERPART OF A COPY OF THIS AGREEMENT WITH ANY
COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY. The parties hereto
expressly incorporate by reference Section 8.16 (Jurisdiction) of the Merger Agreement and, subject to Section 2(i) hereof, Section
8.17 (Remedies) of the Merger Agreement to apply to this Agreement mutatis mutandis, with references to the Merger Agreement therein
deemed to reference this Agreement and references to the “Parties” thereunder deemed to reference the parties hereto.

(e)               
Severability. Whenever possible, each provision of this Agreement will be interpreted in such a manner as to be effective
and valid under applicable Law, but if any term or other provision of this Agreement is held to be invalid, illegal or unenforceable
under applicable Law, all other provisions of this Agreement shall remain in full force and effect so long as the economic or legal
substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party. Upon such determination
that any term or other provision of this Agreement is invalid, illegal or unenforceable under applicable Law, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as
possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated
to the greatest extent possible.


 


(f)                
Construction; Interpretation. The headings set forth in this Agreement are inserted for convenience only and shall
not affect in any way the meaning or interpretation of this Agreement. No party hereto, nor its respective counsel, shall be deemed
the drafter of this Agreement for purposes of construing the provisions hereof, and all provisions of this Agreement shall be construed
according to their fair meaning and not strictly for or against any such party. Unless otherwise indicated to the contrary herein
by the context or use thereof: (a) the words, “herein,” “hereto,” “hereof” and words of similar
import refer to this Agreement as a whole, and not to any particular section, subsection, paragraph, subparagraph or clause set
forth in this Agreement; (b) masculine gender shall also include the feminine and neutral genders, and vice versa; (c) words importing
the singular shall also include the plural, and vice versa; (d) the words “include,” “includes” or “including”
shall be deemed to be followed by the words “without limitation”; (e) references to “$” or “dollar”
or “US$” shall be references to United States dollars; (f) the word “or” is disjunctive but not necessarily
exclusive; (g) the words “writing”, “written” and comparable terms refer to printing, typing and other
means of reproducing words (including electronic media) in a visible form; (h) the word “extent” in the phrase “to
the extent” means the degree to which a subject or other thing extends, and such phrase shall not mean simply “if”;
(i) all references to Articles or Sections are to Articles or Sections of this Agreement; and (j) all references to any Law will
be to such Law as amended, supplemented or otherwise modified from time to time. The parties hereto have participated jointly in
the negotiation and drafting of this Agreement. Consequently, in the event an ambiguity or question of intent or interpretation
arises, this Agreement shall be construed as if drafted jointly by the parties hereto, and no presumption or burden of proof shall
arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.


 


(g)               
Notices. All notices, requests, claims, demands and other communications hereunder shall be in writing and shall
be given (and shall be deemed to have been duly given) when delivered in person, when delivered by e-mail (having obtained electronic

(h)               
Amendments and Waivers. This Agreement may be amended or modified only with the written consent of STPK, the Company,
Sponsor and Holder. The observance of any term of this Agreement may be waived (either generally or in a particular instance, and
either retroactively or prospectively) only with the written consent of the party against whom enforcement of such waiver is sought.
No failure or delay by a party in exercising any right hereunder shall operate as a waiver thereof. No waivers of or exceptions
to any term, condition, or provision of this Agreement, in any one or more instances, shall be deemed to be or construed as a further
or continuing waiver of any such term, condition, or provision. STPK and the Company hereby represent, warrant, covenant and agree
that (i) if any Lock-Up Agreement signed by a stockholder of the Company in connection with the transactions contemplated hereby
is amended, modified or waived in a manner favorable to such stockholder and that would be favorable to Holder, this Agreement
shall be contemporaneously amended in the same manner and STPK shall provide prompt notice thereof to Holder, and (ii) if any such
stockholder is released from any or all of the lock-up restrictions under its Lock-UP Agreement, Holder will be similarly and contemporaneously
released from the lock-up restrictions hereunder (which, for the avoidance, of doubt will include a release of the same percentage
of Holder’s Restricted Securities) and STPK shall provide prompt notice thereof to Holder.


 


(i)                
Authorization on Behalf of STPK. In the event that Holder or Holder’s Affiliate serves as a director, officer,
employee or other authorized agent of STPK or any of its current or future Affiliates, Holder and/or Holder’s Affiliate shall
have no authority, express or implied, to act or make any determination on behalf of STPK or any of its current or future Affiliates
in connection with this Agreement or any dispute or Proceeding with respect hereto.


 


(j)                 Specific
Performance. Holder acknowledges that its obligations under this Agreement are unique, recognizes and affirms that in the
event of a breach of this Agreement by Holder, money damages will be inadequate and STPK and the Company will have no
adequate remedy at law, and agrees that irreparable damage would occur in the event that any of the provisions of this
Agreement were not performed by Holder in accordance with their specific terms or were otherwise breached. Accordingly, each
of STPK and the Company (or Sponsor on their behalf) shall be entitled to an injunction or restraining order to prevent
breaches of this Agreement by Holder and to enforce specifically the terms and provisions hereof, without the requirement to
post any bond or other security or to prove that money damages would be inadequate, this being in addition to any other right
or remedy to which such party may be entitled under this Agreement, at law or in equity.


 






    5


     


    

 


(k)               
Entire Agreement. This Agreement constitutes the full and entire understanding and agreement among the parties with
respect to the subject matter hereof, and any other written or oral agreement relating to the subject matter hereof existing between
the parties is expressly canceled; provided that, for the avoidance of doubt, the foregoing shall not affect the rights
and obligations of the parties under the Merger Agreement or any Ancillary Documents. Notwithstanding the foregoing, nothing in
this Agreement shall limit any of the rights or remedies of STPK and the Company or any of the obligations of Holder under any
other agreement between Holder and STPK or the Company or any certificate or instrument executed by Holder in favor of STPK or
the Company, and nothing in any other agreement, certificate or instrument shall limit any of the rights or remedies of STPK or
the Company or any of the obligations of Holder under this Agreement.


 


(l)                
Further Assurances. From time to time, at another party’s written request and without further consideration
(but at the requesting party’s reasonable cost and expense), each party shall execute and deliver such additional documents
and take all such further action as may be reasonably necessary to consummate the transactions contemplated by this Agreement.


 


(m)             
Counterparts; Electronic Signatures.  This Agreement may be executed in one or more counterparts, each of which
shall be deemed to be an original, but all of which shall constitute one and the same agreement. The words “execution,”
 “signed,” “signature,” and words of like import in this Agreement or in any other certificate, agreement
or document related to this Agreement shall include images of manually executed signatures transmitted by facsimile or other electronic
format (including, “pdf”, “tif” or “jpg”) and other electronic signatures (including, DocuSign
and AdobeSign). The use of electronic signatures and electronic records (including, any contract or other record created, generated,
sent, communicated, received, or stored by electronic means) shall be of the same legal effect, validity and enforceability as
a manually executed signature or use of a paper-based record-keeping system to the fullest extent permitted by applicable law,
including the Federal Electronic Signatures in Global and National Commerce Act, the Delaware Uniform Electronic Transactions Act
and any other applicable law. Minor variations in the form of the signature page, including footers from earlier versions of this
Agreement or any such other document, shall be disregarded in determining the party’s intent or the effectiveness of such
signature.
