SUBSIDIARY
GUARANTEE, dated as of November 4, 2022 (this “Guarantee”), made by each of the signatories hereto (together with
any other entity that may become a party hereto as provided herein, the “Guarantors”), in favor of the purchasers
signatory (together with their permitted assigns, the “Purchasers”) to that certain Securities Purchase Agreement,
dated as of the date hereof, between iSun, Inc., a Delaware corporation (the “Company”), and the Purchasers.


 


W
I T N E S S E T H:


 


WHEREAS,
pursuant to that certain Securities Purchase Agreement, dated as of the date hereof, by and between the Company and the Purchasers (the
“Purchase Agreement”), the Company has agreed to sell and issue to the Purchasers, and the Purchasers have agreed
to purchase from the Company the Notes, subject to the terms and conditions set forth therein; and


 


WHEREAS,
each Guarantor will directly benefit from the extension of credit to the Company represented by the issuance of the Notes; and


 


NOW,
THEREFORE, in consideration of the premises and to induce the Purchasers to enter into the Purchase Agreement and to carry out the transactions
contemplated thereby, each Guarantor hereby agrees with the Purchasers as follows:


 


1.
Definitions. Unless otherwise defined herein, terms defined in the Purchase Agreement and used herein shall have the meanings
given to them in the Purchase Agreement. The words “hereof,” “herein,” “hereto” and “hereunder”
and words of similar import when used in this Guarantee shall refer to this Guarantee as a whole and not to any particular provision
of this Guarantee, and Section and Schedule references are to this Guarantee unless otherwise specified. The meanings given to terms
defined herein shall be equally applicable to both the singular and plural forms of such terms. The following terms shall have the following
meanings:


 


“Guarantee”
means this Subsidiary Guarantee, as the same may be amended, supplemented or otherwise modified from time to time.


 


“Obligations”
means, in addition to all other costs and expenses of collection incurred by Purchasers in enforcing any of such Obligations and/or this
Guarantee, all of the liabilities and obligations (primary, secondary, direct, contingent, sole, joint or several) due or to become due,
or that are now or may be hereafter contracted or acquired, or owing to, of the Company or any Guarantor to the Purchasers, including,
without limitation, all obligations under this Guarantee, the Notes, and any other instruments, agreements or other documents executed
and/or delivered in connection herewith or therewith, in each case, whether now or hereafter existing, voluntary or involuntary, direct
or indirect, absolute or contingent, liquidated or unliquidated, whether or not jointly owed with others, and whether or not from time
to time decreased or extinguished and later increased, created or incurred, and all or any portion of such obligations or liabilities
that are paid, to the extent all or any part of such payment is avoided or recovered directly or indirectly from any of the Purchasers
as a preference, fraudulent transfer or otherwise as such obligations may be amended, supplemented, converted, extended or modified from
time to time. Without limiting the generality of the foregoing, the term “Obligations” shall include, without limitation:
(i) principal of, and interest on the Notes and the loans extended pursuant thereto; (ii) any and all other fees, indemnities, costs,
obligations and liabilities of the Company or any Guarantor from time to time under or in connection with this Guarantee, the Notes,
and any other instruments, agreements or other documents executed and/or delivered in connection herewith or therewith; and (iii) all
amounts (including but not limited to post-petition interest) in respect of the foregoing that would be payable but for the fact that
the obligations to pay such amounts are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar
proceeding involving the Company or any Guarantor.


 




    	 



    	 



    

 


2.
Guarantee.


 


(a)
Guarantee.


 


(i)
The Guarantors hereby, jointly and severally, unconditionally and irrevocably, guarantee to the Purchasers and their respective successors,
indorsees, transferees and assigns, the prompt and complete payment and performance when due (whether at the stated maturity, by acceleration
or otherwise) of the Obligations.


 


(ii)
Anything herein or in any other Transaction Document to the contrary notwithstanding, the maximum liability of each Guarantor hereunder
and under the other Transaction Documents shall in no event exceed the amount which can be guaranteed by such Guarantor under applicable
federal and state laws, including laws relating to the insolvency of debtors, fraudulent conveyance or transfer or laws affecting the
rights of creditors generally (after giving effect to the right of contribution established in Section 2(b)).


 


(iii)
Each Guarantor agrees that the Obligations may at any time and from time to time exceed the amount of the liability of such Guarantor
hereunder without impairing the guarantee contained in this Section 2 or affecting the rights and remedies of the Purchasers hereunder.


 


(iv)
The guarantee contained in this Section 2 shall remain in full force and effect until all the Obligations and the obligations of each
Guarantor under the guarantee contained in this Section 2 shall have been satisfied by indefeasible payment in full.


 


(v)
No payment made by the Company, any of the Guarantors, any other guarantor or any other Person or received or collected by the Purchasers
from the Company, any of the Guarantors, any other guarantor or any other Person by virtue of any action or proceeding or any set-off
or appropriation or application at any time or from time to time in reduction of or in payment of the Obligations shall be deemed to
release or otherwise affect the liability of any Guarantor hereunder which shall, notwithstanding any such payment (other than any payment
made by such Guarantor in respect of the Obligations or any payment received or collected from such Guarantor in respect of the Obligations),
remain liable for the Obligations up to the maximum liability of such Guarantor hereunder until the Obligations are indefeasibly paid
in full.


 




    	2



    	 



    

 


(vi)
Notwithstanding anything to the contrary in this Guarantee, with respect to any defaulted non-monetary Obligations the specific performance
of which by the Guarantors is not reasonably possible (e.g. the issuance of the Company’s Common Stock), the Guarantors shall only
be liable for making the Purchasers whole on a monetary basis for the Company’s failure to perform such Obligations in accordance
with the Transaction Documents.


 


(b)
Right of Contribution. Subject to Section 2(c), each Guarantor hereby agrees that to the extent that a Guarantor shall have paid
more than its proportionate share of any payment made hereunder, such Guarantor shall be entitled to seek and receive contribution from
and against any other Guarantor hereunder which has not paid its proportionate share of such payment. Each Guarantor’s right of
contribution shall be subject to the terms and conditions of Section 2(c). The provisions of this Section 2(b) shall in no respect limit
the obligations and liabilities of any Guarantor to the Purchasers and each Guarantor shall remain liable to the Purchasers for the full
amount guaranteed by such Guarantor hereunder.


 


(c)
No Subrogation. Notwithstanding any payment made by any Guarantor hereunder or any set-off or application of funds of any Guarantor
by the Purchasers, no Guarantor shall be entitled to be subrogated to any of the rights of the Purchasers against the Company or any
other Guarantor or any collateral security or guarantee or right of offset held by the Purchasers for the payment of the Obligations,
nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from the Company or any other Guarantor in respect
of payments made by such Guarantor hereunder, until all amounts owing to the Purchasers by the Company on account of the Obligations
are indefeasibly paid in full. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all
of the Obligations shall not have been paid in full, such amount shall be held by such Guarantor in trust for the Purchasers, segregated
from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Purchasers in the exact
form received by such Guarantor (duly indorsed by such Guarantor to the Purchasers, if required), to be applied against the Obligations,
whether matured or unmatured, in such order as the Purchasers may determine.


 


(d)
Amendments, Etc. With Respect to the Obligations. Each Guarantor shall remain obligated hereunder notwithstanding that, without
any reservation of rights against any Guarantor and without notice to or further assent by any Guarantor, any demand for payment of any
of the Obligations made by the Purchasers may be rescinded by the Purchasers and any of the Obligations continued, and the Obligations,
or the liability of any other Person upon or for any part thereof, or any collateral security or guarantee therefor or right of offset
with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised,
waived, surrendered or released by the Purchasers, and the Purchase Agreement and the other Transaction Documents and any other documents
executed and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as the Purchasers
may deem advisable from time to time, and any collateral security, guarantee or right of offset at any time held by the Purchasers for
the payment of the Obligations may be sold, exchanged, waived, surrendered or released. The Purchasers shall have no obligation to protect,
secure, perfect or insure any Lien at any time held by them as security for the Obligations or for the guarantee contained in this Section
2 or any property subject thereto.


 




    	3



    	 



    

 


(e)
Guarantee Absolute and Unconditional. Each Guarantor waives any and all notice of the creation, renewal, extension or accrual
of any of the Obligations and notice of or proof of reliance by the Purchasers upon the guarantee contained in this Section 2 or acceptance
of the guarantee contained in this Section 2; the Obligations, and any of them, shall conclusively be deemed to have been created, contracted
or incurred, or renewed, extended, amended or waived, in reliance upon the guarantee contained in this Section 2; and all dealings between
the Company and any of the Guarantors, on the one hand, and the Purchasers, on the other hand, likewise shall be conclusively presumed
to have been had or consummated in reliance upon the guarantee contained in this Section 2. Each Guarantor waives to the extent permitted
by law diligence, presentment, protest, demand for payment and notice of default or nonpayment to or upon the Company or any of the Guarantors
with respect to the Obligations. Each Guarantor understands and agrees that the guarantee contained in this Section 2 shall be construed
as a continuing, absolute and unconditional guarantee of payment and performance without regard to (a) the validity or enforceability
of the Purchase Agreement or any other Transaction Document, any of the Obligations or any other collateral security therefor or guarantee
or right of offset with respect thereto at any time or from time to time held by the Purchasers, (b) any defense, set-off or counterclaim
(other than a defense of payment or performance or fraud by Purchasers) which may at any time be available to or be asserted by the Company
or any other Person against the Purchasers, or (c) any other circumstance whatsoever (with or without notice to or knowledge of the Company
or such Guarantor) which constitutes, or might be construed to constitute, an equitable or legal discharge of the Company for the Obligations,
or of such Guarantor under the guarantee contained herein, in bankruptcy or in any other instance. When making any demand hereunder or
otherwise pursuing its rights and remedies hereunder against any Guarantor, the Purchasers may, but shall be under no obligation to,
make a similar demand on or otherwise pursue such rights and remedies as they may have against the Company, any other Guarantor or any
other Person or against any collateral security or guarantee for the Obligations or any right of offset with respect thereto, and any
failure by the Purchasers to make any such demand, to pursue such other rights or remedies or to collect any payments from the Company,
any other Guarantor or any other Person or to realize upon any such collateral security or guarantee or to exercise any such right of
offset, or any release of the Company, any other Guarantor or any other Person or any such collateral security, guarantee or right of
offset, shall not relieve any Guarantor of any obligation or liability hereunder, and shall not impair or affect the rights and remedies,
whether express, implied or available as a matter of law, of the Purchasers against any Guarantor. For the purposes hereof, “demand”
shall include the commencement and continuance of any legal proceedings.


 




    	4



    	 



    

 


(f)
Reinstatement. The guarantee contained in this Section 2 shall continue to be effective, or be reinstated, as the case may be,
if at any time payment, or any part thereof, of any of the Obligations is rescinded or must otherwise be restored or returned by the
Purchasers upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Company or any Guarantor, or upon or as
a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the Company or any Guarantor
or any substantial part of its property, or otherwise, all as though such payments had not been made.


 


(g)
Payments. Each Guarantor hereby guarantees that payments hereunder will be paid to the Purchasers without set-off or counterclaim
in U.S. dollars at the address set forth or referred to in the Signature Pages to the Purchase Agreement.


 


3.
Representations and Warranties. Each Guarantor hereby makes the following representations and warranties to Purchasers as of the
date hereof:


 


(a)
Organization and Qualification. The Guarantor is a corporation or limited liability company, as applicable, duly incorporated
or organized, as applicable, validly existing and in good standing under the laws of the applicable jurisdiction set forth on Schedule
1, with the requisite corporate or limited liability company power and authority to own and use its properties and assets and to
carry on its business as currently conducted. No Guarantor has any subsidiaries other than those identified as such on the Disclosure
Schedules to the Purchase Agreement. Each Guarantor is duly qualified to do business and is in good standing as a foreign corporation
in each jurisdiction in which the nature of the business conducted or property owned by it makes such qualification necessary, except
where the failure to be so qualified or in good standing, as the case may be, could not, individually or in the aggregate, (x) adversely
affect the legality, validity or enforceability of this Guaranty in any material respect, (y) have a material adverse effect on the results
of operations, assets, prospects, or financial condition of the Guarantor or (z) adversely impair in any material respect the Guarantor’s
ability to perform fully on a timely basis its obligations under this Guaranty (a “Material Adverse Effect”).


 


(b)
Authorization; Enforcement. Each Guarantor has the requisite corporate or limited liability company power and authority to enter
into and to consummate the transactions contemplated by this Guaranty, and otherwise to carry out its obligations hereunder. The execution
and delivery of this Guaranty by each Guarantor and the consummation by it of the transactions contemplated hereby have been duly authorized
by all requisite corporate or limited liability company action on the part of the Guarantor. This Guaranty has been duly executed and
delivered by each Guarantor and constitutes the valid and binding obligation of such Guarantor enforceable against such Guarantor in
accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium,
liquidation or similar laws relating to, or affecting generally the enforcement of, creditors’ rights and remedies or by other
equitable principles of general application.


 




    	5



    	 



    

 


(c)
No Conflicts. The execution, delivery and performance of this Guaranty by each Guarantor and the consummation by each Guarantor
of the transactions contemplated thereby do not and will not (i) conflict with or violate any provision of its Certificate or Articles
of Incorporation, Bylaws or other organizational or charter documents (each as applicable), or (ii) conflict with, constitute a default
(or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment,
acceleration or cancellation of, any agreement, indenture or instrument to which the Guarantor is a party, or (iii) result in a violation
of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which
any Guarantor is subject (including Federal and State securities laws and regulations), or by which any material property or asset of
any Guarantor is bound or affected, except in the case of each of clauses (ii) and (iii), such conflicts, defaults, terminations, amendments,
accelerations, cancellations and violations as could not, individually or in the aggregate, have or result in a Material Adverse Effect.
The business of the Guarantor is not being conducted in violation of any law, ordinance or regulation of any governmental authority,
except for violations which, individually or in the aggregate, do not have a Material Adverse Effect.


 


(d)
Consents and Approvals. No Guarantor is required to obtain any consent, waiver, authorization or order of, or make any filing
or registration with, any court or other federal, state, local, foreign or other governmental authority or other person in connection
with the execution, delivery and performance by such Guarantor of this Guaranty.


 


(e)
Purchase Agreement. The representations and warranties of the Company set forth in the Purchase Agreement as they relate to such
Guarantor, each of which is hereby incorporated herein by reference, are true and correct as of each time such representations are deemed
to be made pursuant to such Purchase Agreement, and the Purchasers shall be entitled to rely on each of them as if they were fully set
forth herein, provided that each reference in each such representation and warranty to the Company’s knowledge shall, for the purposes
of this Section 3, be deemed to be a reference to such Guarantor’s knowledge.


 


(f)
Foreign Law. Each Guarantor has had the opportunity to consult with appropriate foreign legal counsel with respect to any of the
above representations for which non-U.S. law is applicable.


 


4.
Covenants.


 


(a)
Each Guarantor covenants and agrees with the Purchasers that, from and after the date of this Guarantee until the Obligations shall have
been indefeasibly paid in full, such Guarantor shall take, and/or shall refrain from taking, as the case may be, each commercially reasonable
action that is necessary to be taken or not taken, as the case may be, so that no Event of Default (as defined in the Notes) is caused
by the failure to take such action or to refrain from taking such action by such Guarantor.


 


(b)
So long as any of the Obligations are outstanding, each Guarantor will not directly or indirectly on or after the date of this Guarantee:


 


(i)
Except as permitted under the Purchase Agreement, enter into, create, incur, assume or suffer to exist any indebtedness for borrowed
money of any kind, including but not limited to, a guarantee, on or with respect to any of its property or assets now owned or hereafter
acquired or any interest therein or any income or profits therefrom;


 




    	6



    	 



    

 


(ii)
Except as permitted under the Purchase Agreement, enter into, create, incur, assume or suffer to exist any liens of any kind, on or with
respect to any of its property or assets now owned or hereafter acquired or any interest therein or any income or profits therefrom;


 


(iii)
Amend its Certificate or Articles of Incorporation, Bylaws or other organizational or charter documents (each as applicable) so as to
adversely affect any rights of any Purchaser;


 


(iv)
repay, repurchase or offer to repay, repurchase or otherwise acquire more than a de minimis number of shares of its securities or debt
obligations;


 


(v)
pay cash dividends on any equity securities of the Company;


 


(vi)
enter into any transaction with any Affiliate of the Guarantor which would be required to be disclosed in any public filing of the Company
with the Commission, unless such transaction is made on an arm’s-length basis and expressly approved by a majority of the disinterested
directors of the Company (even if less than a quorum otherwise required for Board approval); or


 


(vii)
enter into any agreement with respect to any of the foregoing.


 


5.
Miscellaneous.


 


(a)
Amendments in Writing. None of the terms or provisions of this Guarantee may be waived, amended, supplemented or otherwise modified
except in writing by the Purchasers.


 


(b)
Notices. All notices, requests and demands to or upon the Purchasers or any Guarantor hereunder shall be effected in the manner
provided for in the Purchase Agreement, provided that any such notice, request or demand to or upon any Guarantor shall be addressed
to such Guarantor at its notice address set forth on Schedule 5(b).


 


(c)
No Waiver By Course Of Conduct; Cumulative Remedies. The Purchasers shall not by any act (except by a written instrument pursuant
to Section 5(a)), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced
in any default under the Transaction Documents or Event of Default (as defined in the Notes). No failure to exercise, nor any delay in
exercising, on the part of the Purchasers, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial
exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. A waiver by the Purchasers of any right or remedy hereunder on any one occasion shall not be construed as
a bar to any right or remedy which the Purchasers would otherwise have on any future occasion. The rights and remedies herein provided
are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law.


 




    	7



    	 



    

 


(d)
Enforcement Expenses; Indemnification.


 


(i)
Each Guarantor agrees to pay, or reimburse the Purchasers for, all its costs and expenses incurred in collecting against such Guarantor
under the guarantee contained in Section 2 or otherwise enforcing or preserving any rights under this Guarantee and the other Transaction
Documents to which such Guarantor is a party, including, without limitation, the reasonable fees and disbursements of counsel to the
Purchasers.


 


(ii)
Each Guarantor agrees to pay, and to save the Purchasers harmless from, any and all liabilities with respect to, or resulting from any
delay in paying, any and all stamp, excise, sales or other taxes which may be payable or determined to be payable in connection with
any of the transactions contemplated by this Guarantee.


 


(iii)
Each Guarantor agrees to pay, and to save the Purchasers harmless from, any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to the execution, delivery,
enforcement, performance and administration of this Guarantee to the extent the Company would be required to do so pursuant to the Purchase
Agreement.


 


(iv)
The agreements in this Section shall survive repayment of the Obligations and all other amounts payable under the Purchase Agreement
and the other Transaction Documents.


 


(e)
Successor and Assigns. This Guarantee shall be binding upon the successors and assigns of each Guarantor and shall inure to the
benefit of the Purchasers and their respective successors and assigns; provided that no Guarantor may assign, transfer or delegate any
of its rights or obligations under this Guarantee without the prior written consent of the Purchasers.


 


(f)
Set-Off. Each Guarantor hereby irrevocably authorizes the Purchasers at any time and from time to time while an Event of Default
(as defined in the Notes) under the Notes or a default under any of the Transaction Documents shall have occurred and be continuing,
without notice to such Guarantor or any other Guarantor, any such notice being expressly waived by each Guarantor, to set-off and appropriate
and apply any and all deposits, credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or
contingent, matured or unmatured, at any time held or owing by the Purchasers to or for the credit or the account of such Guarantor,
or any part thereof in such amounts as the Purchasers may elect, against and on account of the obligations and liabilities of such Guarantor
to the Purchasers hereunder and claims of every nature and description of the Purchasers against such Guarantor, in any currency, whether
arising hereunder, under the Purchase Agreement, any other Transaction Document or otherwise, as the Purchasers may elect, whether or
not the Purchasers have made any demand for payment and although such obligations, liabilities and claims may be contingent or unmatured.
The Purchasers shall notify such Guarantor promptly of any such set-off and the application made by the Purchasers of the proceeds thereof,
provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of the Purchasers
under this Section are in addition to other rights and remedies (including, without limitation, other rights of set-off) which the Purchasers
may have.


 




    	8



    	 



    

 


(g)
Counterparts. This Guarantee may be executed by two or more of the parties to this Guarantee on any number of separate counterparts
(including by telecopy), and all of said counterparts taken together shall be deemed to constitute one and the same instrument.


 


(h)
Severability. Any provision of this Guarantee which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such
prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.


 


(i)
Section Headings. The Section headings used in this Guarantee are for convenience of reference only and are not to affect the
construction hereof or be taken into consideration in the interpretation hereof.

respect to the subject matter hereof and thereof, and there are no promises, undertakings, representations or warranties by the Purchasers
relative to subject matter hereof and thereof not expressly set forth or referred to herein or in the other Transaction Documents.


 


(k)
Governing Laws. All questions concerning the construction, validity, enforcement and interpretation of this Guarantee shall be
governed by and construed and enforced in accordance with the internal laws of the State of Delaware, without regard to the principles
of conflicts of law thereof. Each of the Company and the Guarantors agree that all proceedings concerning the interpretations, enforcement
and defense of the transactions contemplated by this Guarantee (whether brought against a party hereto or its respective affiliates,
directors, officers, shareholders, partners, members, employees or agents) shall be commenced exclusively in the state and federal courts
sitting in the State of Delaware. Each of the Company and the Guarantors hereby irrevocably submits to the exclusive jurisdiction of
the state and federal courts sitting in the State of Delaware for the adjudication of any dispute hereunder or in connection herewith
or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any proceeding,
any claim that it is not personally subject to the jurisdiction of any such court, that such proceeding is improper. Each party hereto
hereby irrevocably waives personal service of process and consents to process being served in any such proceeding by mailing a copy thereof
via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices
to it under this Guarantee and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing
contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. Each party hereto hereby
irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising
out of or relating to this Guarantee or the transactions contemplated hereby.

it has been advised by counsel in the negotiation, execution and delivery of this Guarantee and the other Transaction Documents to which
it is a party;


 


(ii)
the Purchasers have no fiduciary relationship with or duty to any Guarantor arising out of or in connection with this Guarantee or any

the Purchase Agreement) of such Guarantor.


 


(p)
