          	(b)

          	(c)	
            publicly announce any intention to effect any transaction specified in clauses (a) or (b).

          


    

    

    As used herein, the term “Lockup Period”, with respect to any Shares, means the period beginning on the date such Shares are issued   (each such date, an  “Issue  Date”) and ending on the date that is

    	2.	
            Notwithstanding the provisions of paragraph 1 above, Stockholder may transfer any of the Shares:

          	(b)	
            by virtue of the applicable laws upon dissolution of Stockholder, if the Stockholders is a legal entity;

          


    

    

    	

          	(c)	
            by virtue of the Laws of descent and distribution upon the death of Stockholder, as applicable; or

          


    

    

    	

          	(d)	
            to any of Stockholder’s Affiliates;

          


    

    

    provided, however, that (i) all such permitted transferees shall execute and deliver a lockup agreement substantially in the form of this Agreement and shall be bound by the transfer restrictions
      contained herein, (ii) any such transfers shall not involve a disposition for value (other than as described above in clause (b)), (iii) any such transfers that result in a reduction of beneficial ownership of the Shares are not required to be
      reported with the Securities and Exchange Commission (the “SEC”) on Form 4 pursuant to Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and (iv) the undersigned does not otherwise voluntarily effect any public
      filing or report regarding such transfers.

    

    

    For purposes of this Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin.

    

    

    	3.

              agent and registrar against the transfer of the Shares, except in compliance with this Agreement, and iSun and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a
              violation or breach of this Agreement.

          


    

    

    	5.	
            This Agreement constitutes the entire agreement by the parties hereto and supersedes all prior understandings, agreements, or representations by the parties hereto, written or oral, to the extent that they relate in
              any way to the subject matter hereof.

          


    

    

    	6.	
            This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns.

          


    

    

    	7.	
            This Agreement and any claim, controversy or dispute arising out of or related to this Agreement or the interpretation and enforcement of the rights and duties of the parties hereto, whether arising in law or
              equity, whether in contract, tort, under statute or otherwise, shall be governed by and construed in accordance with the domestic laws of the State of Delaware (including in respect of the statute of limitations or other limitations period
              applicable to any such claim, controversy or dispute), without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any
              jurisdiction other than the State of Delaware.

          


    

    

    
      2

      
        


    

    

    

    	8.	
            All notices, requests, demands, claims, and other communications hereunder shall be in writing. Any notice, request, demand, claim, or other communication hereunder shall be deemed duly given (a) when delivered
              personally to the recipient, (b) when sent by electronic mail or facsimile, on the date of transmission to such recipient, (c) one Business Day after being sent to the recipient by reputable overnight courier service (charges prepaid), or (d)
              four (4) Business Days after being mailed to the recipient by certified or registered mail, return receipt requested and postage prepaid, and addressed to the address or facsimile number indicated on the books and records of iSun or such
              other address as a party hereto shall subsequently provide.

          


    

    

    	9.	
            No amendment of any provision of this Agreement shall be valid unless the same shall be in writing and signed by the parties hereto and approved in writing by the Audit Committee of the Board of Directors of iSun.
              No waiver by any party hereto of any provision of this Agreement or any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not, shall be valid unless the same shall be in writing and signed by the
              party making such waiver and, in the case of iSun, approved in writing by the Audit Committee of the Board of Directors of iSun nor shall such waiver be deemed to extend to any prior or subsequent default, misrepresentation, or breach of
              warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such occurrence.

          


    

    

    	10.	
            Each of the parties hereto has been informed that irreparable damage would occur if any of the provisions of this Agreement are not performed in accordance with their specific terms and in the event of breach of
              this Agreement by a party hereto, the non-breaching party would not be adequately compensated in all cases by monetary damages alone. Accordingly, in addition to any other right or remedy to which the non-breaching party may be entitled, such
              party shall be entitled to seek to enforce any provision of this Agreement by a decree of specific performance and to temporary, preliminary and permanent injunctive relief to prevent breaches or threatened breaches of any of the provisions
              of this Agreement, without posting any bond or other undertaking.

          


    

    

    	11.	
            If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of Law, or public policy, all other conditions and provisions of this Agreement shall nevertheless
              remain in full force and effect so long as the economic or legal substance of the transactions contemplated by this Agreement is not affected in any manner materially adverse to any party hereto. Upon such determination that any term or other
              provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of such parties as closely as possible in a mutually acceptable manner
              in order that the transactions contemplated by this Agreement be consummated as originally contemplated to the fullest extent possible.

          


    

    

    	12.	
            This Agreement may be executed in one or more counterparts (including by means of electronic mail or facsimile), each of which shall be deemed an original but all of which together shall constitute one and the same
              instrument. This Agreement shall become effective when each party hereto shall have received a counterpart hereof signed by the other party hereto. The parties hereto agree that the delivery of this Agreement may be effected by means of an
              exchange of facsimile signatures or other electronic delivery.
