AGREEMENT

In consideration of the mutual promises contained herein, and other good and valuable consideration, the parties hereto agree as follows:

1.        Subscription. Subject to and in accordance with the respective terms and conditions of this Agreement, in consideration for the full cancellation of $350,000 of the Accounts Payable otherwise due from the Company to Subscriber, Subscriber agrees to purchase from the Company, and the Company agrees to sell to Subscriber, in each case immediately effective prior to the consummation of the Merger, a convertible note of the Company (the “Convertible Note”) that will automatically convert into 175,000 Class C Units of the Company after issuance of the Convertible Note to Subscriber and immediately prior to the consummation of the Merger (the Class C Units being issued to Subscriber upon conversion of the Convertible Note are hereinafter collectively referred to as the “Units”). Prior to the Closing of the Merger, the Company shall submit the form of Convertible Note to Subscriber for its approval, which approval shall not be unreasonably withheld.

2.        Joinder and Conversion. Upon consummation of this Agreement, Subscriber covenants and agrees (i) to take all actions reasonably requested by the Company to approve and consent to the Merger and the other transactions contemplated by the Merger Agreement, including executing a joinder agreement in substantially the form attached hereto as Exhibit A, (ii) that at the Effective Time (as defined in the Merger Agreement), the Class C Units to be issued to Subscriber upon conversion of the Convertible Note pursuant to Section 1 hereof will automatically convert into the consideration contemplated by Section 2.6(e) of the Merger Agreement, and (iii) upon issuance of the Convertible Note, all rights of Subscriber with respect to the Accounts Payable shall automatically be cancelled, terminated and of no further force or effect. Notwithstanding the foregoing, this Agreement shall automatically

terminate and be of no further force and effect without further action of either party hereto upon the termination of the Merger Agreement in accordance with its terms.

3.           Representations and Warranties of Subscriber. In consideration of the Company’s agreement to sell the Units, Subscriber hereby represents and warrants to the Company as follows:

a.         Information About the Company. Subscriber has had an opportunity to ask questions of, and receive answers from, the Company concerning the business, management and financial affairs of the Company and the terms and conditions of the purchase of the Convertible Note and Units contemplated hereby. Subscriber has had an opportunity to obtain any information requested by Subscriber regarding the Company, including information regarding the current financial condition of the Company, as well as any information requested to verify this information. Subscriber has received and carefully reviewed that certain Second Amended and Restated Limited Liability Company Agreement of the Company, effective as of December 1, 2020, as amended, modified, supplemented, or waived (the “LLCA”), that will govern the Company from and after the effective date of this Agreement. 

b.        High Degree of Risk. Subscriber understands that the Company has a limited operating history and that its financial projections, if any, are purely speculative.  Subscriber realizes that an investment in the Convertible Note and Units involves a high degree of risk, including the risks of receiving no return on the investment and of losing Subscriber’s entire investment in the Company.  Subscriber is able to bear the economic risk of investment in the Convertible Note and Units, including the total loss of such investment. The Subscriber acknowledges that Company can make no assurance regarding its future financial performance or as to the future profitability of the Company.

c.         No Market for Units; Restrictions on Transfer. Subscriber realizes that (i) there are substantial restrictions on the transfer of the Units in the LLCA and under applicable law; (ii) there is not currently, and there can be no guarantee that in the future there will exist, a public market for the Units; (iii) the Company has not developed a specific exit strategy for its investors; and (iv) accordingly, for the above and other reasons, Subscriber may not be able to liquidate an investment in the Convertible Note and Units for an indefinite period. Subscriber acknowledges that the Units have not been registered for sale under the Securities Act of 1933, as amended (the “Securities Act”), or applicable state securities laws (the “State Laws”), and agrees that the Units may be sold only pursuant to registration under the Securities Act and State Laws, or, in the sole discretion of the Company, upon receipt by the Company (at Subscriber’s expense) of an opinion of counsel acceptable to the Company that such registration is not required.

d.        Suitability.  Subscriber has such knowledge and experience in financial and business matters that Subscriber is capable of evaluating the merits and risks of an investment in the Convertible Note and Units. Subscriber has obtained, to the extent deemed necessary, Subscriber’s own personal professional advice with respect to the risks inherent in, and the suitability of, an investment in the Convertible Note and Units in light of Subscriber’s financial condition and investment needs. Subscriber believes that the investment in the Convertible Note and Units is suitable for Subscriber based upon Subscriber’s investment objectives and financial needs, and Subscriber has adequate means for providing for Subscriber’s current financial needs and personal contingencies and has no need for liquidity of investment with respect to the Convertible Note and Units. Subscriber understands that no federal or state agency has made any finding or determination as to the fairness for investment, nor any recommendation or endorsement, of the Convertible Note and Units. Subscriber acknowledges that neither the Company nor its professional advisors has or will provide Subscriber with investment, business, legal, tax or other advice with respect to Subscriber’s investment in the Units.

e.         Investment Intent. Subscriber has been advised that the Convertible Note and Units are not being registered under the Securities Act or the relevant State Laws, but are being offered and sold pursuant to exemptions from such laws and that the Company’s reliance upon such exemptions

Subscription Agreement – Pineapple Energy LLC Page 2

is predicated in part on Subscriber’s representations to the Company as contained herein. Subscriber represents and warrants that the Convertible Note and Units are being purchased for Subscriber’s own account and for Subscriber’s investment and without the intention of reselling or redistributing the same, that Subscriber has made no agreement with others regarding any of such Convertible Note and Units, and that Subscriber’s financial condition is such that it is not likely that it will be necessary to dispose of any of the Convertible Note and Units in the foreseeable future.  Subscriber is aware that there is no market for the Convertible Note and Units and that it is likely that such a market will never develop. Accordingly, it is unlikely that Subscriber will be able to liquidate an investment in the Company in case of an emergency or for any other reason. Subscriber is aware that, in the view of the Securities and Exchange Commission, a purchase of the Convertible Note and Units with an intent to resell by reason of any foreseeable specific contingency or anticipated change in market values, or any change in the condition of the Company, or in connection with a contemplated liquidation or settlement of any loan obtained for the acquisition of the Convertible Note and Units and for which the Convertible Note and Units were pledged as security, would represent an intent inconsistent with the representations set forth above. Subscriber further represents and agrees that if, contrary to the foregoing stated intentions, Subscriber should later desire to dispose of or transfer any of the Convertible Note and Units in any manner, Subscriber will not do so without first obtaining (i) the opinion of counsel satisfactory to the Company that such proposed disposition or transfer lawfully may be made without the registration of the Units pursuant to the Securities Act and applicable State Laws, or (ii) such registration (it being expressly understood that the Company shall not have any obligation to register such Convertible Note or Units for such purpose).

f.         Residence.  The office of Subscriber in which its investment decision was made is located at the address or addresses of Subscriber set forth on the signature page hereto.

g.         Tax Liability. 

i.         Subscriber has reviewed with Subscriber’s own tax advisors the federal, state, local and foreign tax consequences of an investment in the Convertible Note and Units and the transactions contemplated by this Agreement, and has and will rely solely on such advisors and not on any statements or representations of the Company or any of its agents. Subscriber understands that Subscriber (and not the Company) shall be responsible for Subscriber’s own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement.

ii.        Under penalties of perjury, Subscriber certifies that (a) the number shown on the signature page below is Subscriber’s correct social security or taxpayer identification number and (b) Subscriber is not subject to back-up withholding either because Subscriber has not been notified that Subscriber is subject to back-up withholding as a result of a failure to report all interest and dividends, or because the Internal Revenue Service has notified Subscriber that Subscriber is no longer subject to back-up withholding.

h.        Limitation Regarding Representations. Except as set forth in this Agreement, no representations or warranties have been made to Subscriber by the Company or any agent, employee, officer, director or affiliate of the Company, and in entering into this transaction, Subscriber is not relying on any information, other than that contained herein and the results of independent investigation by Subscriber. Subscriber agrees that it is not relying on any oral or written information not expressly included in this Agreement, including but not limited to the information which has been provided by the Company, its officers, its directors, or any affiliate of any of the foregoing.

i.         Withdrawal.  Subscriber realizes that Subscriber will not be allowed to withdraw Subscriber’s investment for any reason after the Company accepts Subscriber’s subscription.  Subscriber acknowledges an investment in the Units should be considered a long-term investment.

j.         No Brokers. Subscriber has not retained any broker in connection with the transactions contemplated by this Agreement. Subscriber represents and warrants that the Company will

Subscription Agreement – Pineapple Energy LLC Page 3

not have any obligation to pay any broker’s, finder’s, investment banker’s, financial advisor’s or similar fee in connection with this Agreement or the transactions contemplated by this Agreement by reason of any action taken by or on behalf of Subscriber.

4.        Accredited Status. Subscriber represents and warrants that Subscriber is an accredited investor as defined in Regulation D promulgated under the Securities Act. Specifically, Subscriber represents and warrants that it is a corporation with total assets in excess of $5,000,000. The information provided under this section is required in connection with the exemptions from the Securities Act and the State Laws being relied on by the Company with respect to the offer and sale of the Convertible Note and Units. The undersigned Subscriber agrees to furnish any additional information which the Company or its legal counsel deem necessary to verify the responses set forth below.

5.           Holding Status. Subscriber desires that the Convertible Note and Units be held as set forth on the signature page hereto.

6.           [Reserved]

7.           Miscellaneous.

a.         Survival of Representations and Warranties; Indemnification. Subscriber understands the meaning and legal consequences of the agreements, representations and warranties contained herein, agrees that such agreements, representations and warranties shall survive and remain in full force and effect after the execution hereof and payment for the Convertible Note and Units, and further agrees to indemnify and hold harmless the Company and each current, former and future officer, director, member, managing member, manager, employee, representative, and agent of the Company from and against any and all loss, damage or liability due to, or arising out of, a breach of any agreement, representation or warranty of the undersigned Subscriber contained herein. 

b.        No Assignment or Revocation; Binding Effect.  Neither this Agreement, nor any interest herein, shall be assignable by Subscriber without the prior written consent of the Company. Except as otherwise set forth above, Subscriber hereby acknowledges and agrees that Subscriber is not entitled to cancel, terminate or revoke this Agreement and that it shall survive the death, incapacity or bankruptcy of Subscriber. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto, and their respective heirs, legal representatives, successors and assigns.

c.        Remedies. Subscriber acknowledges that the Company may not have an adequate remedy at law in the event of any breach of this Agreement by Subscriber and, therefore, the Company will be entitled, in addition to any other available remedies, to injunctive and/or other equitable relief to prevent or remedy a breach of this Agreement and to reasonable attorneys’ fees and other costs actually incurred by the Company in commencing suit or taking other action to enforce the terms and conditions of this Agreement.

d.        Modifications.  This Agreement may not be changed, modified, released, discharged, abandoned or otherwise amended, in whole or in part, except by an instrument in writing, signed by Subscriber and the Company. No delay or failure of the Company in exercising any right under this Agreement will be deemed to constitute a waiver of such right or of any other rights.

e.        Entire Agreement. This Agreement and the schedules hereto are the entire agreement between the parties with respect to the subject matter hereto and thereto. This Agreement, including the schedules and signature pages hereto, supersedes any previous oral or written communications, representations, understandings or agreements with the Company or with any officers, directors, employees, agents or other representatives of the Company. 

f.         Severability.  In the event that any paragraph or provision of this Agreement shall be held to be illegal or unenforceable in any jurisdiction, such paragraph or provision shall, as to that jurisdiction, be adjusted and reformed, if possible, in order to achieve the intent of the parties, and if

Subscription Agreement – Pineapple Energy LLC Page 4

such paragraph or provision cannot be adjusted and reformed, such paragraph or provision shall, for the purposes of that jurisdiction, be voided and severed from this Agreement, and the entire Agreement shall not fail on account thereof but shall otherwise remain in full force and effect.

g.        Governing Law.  This Agreement shall be governed by, subject to, and construed in accordance with the laws of the State of Delaware without regard to conflict of law principles.

h.        Jurisdiction and Venue. Subscriber and the Company consent to jurisdiction of the courts in the State of Minnesota for the purpose of resolving all issues of law, equity, or fact, arising out of or in connection with this Agreement. Any action involving claims of a breach of this Agreement may be brought in such courts. Subscriber and the Company consent to personal jurisdiction in the state and federal courts of Minnesota and hereby waive any defense of lack of personal jurisdiction. Venue, for the purpose of all such suits, will be in the State of Minnesota. SUBSCRIBER HEREBY AGREES TO WAIVE ANY RIGHT TO TRIAL BY JURY WITH RESPECT TO ANY CLAIM, COUNTERCLAIM OR ACTION ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE LLCA.

No failure by any party to take any action against any breach of this Joinder Agreement or default by another party shall constitute a waiver of the former party’s right to enforce any provision of this Joinder Agreement or to take action against such breach or default or any subsequent breach or default by the other party. To be effective any waiver must be in writing and signed by the waiving party (or such party’s attorney-in-fact).

8.7 Governing Law; Venue; Waiver of Jury Trial.

(a)       This Joinder Agreement shall be governed by the Laws of the State of Minnesota, without giving effect to any choice of law or conflict of law provision or rule that would cause application of the Laws of any jurisdiction other than the State of Minnesota.

(b)       Parent and Member each (i) consents to submit itself to the exclusive personal jurisdiction of the state and federal courts located in Minneapolis, Minnesota (the “Chosen Court”) in any action or proceeding arising out of or relating to this Agreement, (b) agrees that all claims in respect of such action or proceeding shall be heard and determined in any such Chosen Court, (c) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such Chosen Court and (d) agrees not to bring any action or proceeding arising out of or relating to this Joinder Agreement in any other court. Parent and Member each waives any defense of inconvenient forum to the maintenance of any action or proceeding so brought and waives any bond, surety or other security that might be required of any other party with respect thereto. Any party may make service on another party by sending or delivering a copy of the process to the party to be served at the address and in the manner provided for the giving of notices in Section 8.11. Nothing in this Section 8.7, however, shall affect the right of any party to serve legal process in any other manner permitted by law.

(c)       Each party waives any claim and will not assert that venue should properly lie in any other location within the selected jurisdiction.

(d)       TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW THAT CANNOT BE WAIVED, THE PARTIES HEREBY WAIVE, AND COVENANT THAT THEY WILL NOT ASSERT (WHETHER AS PLAINTIFF, DEFENDANT OR OTHERWISE), ANY RIGHT TO TRIAL BY JURY IN ANY ACTION ARISING IN WHOLE OR IN PART UNDER OR IN CONNECTION WITH THIS JOINDER AGREEMENT OR ANY OF THE CONTEMPLATED TRANSACTIONS, WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE. THE PARTIES AGREE THAT ANY OF THEM MAY FILE A COPY OF THIS PARAGRAPH WITH ANY COURT AS WRITTEN EVIDENCE OF THE KNOWING, VOLUNTARY AND BARGAINED-FOR AGREEMENT AMONG THE PARTIES IRREVOCABLY TO WAIVE ITS RIGHT TO TRIAL BY JURY IN ANY PROCEEDING WHATSOEVER BETWEEN THEM RELATING TO THIS JOINDER AGREEMENT OR ANY OF THE CONTEMPLATED TRANSACTIONS, AND SUCH PROCEEDING WILL INSTEAD BE TRIED IN A COURT OF COMPETENT JURISDICTION BY A JUDGE SITTING WITHOUT A JURY.

8.8      Specific Performance. The rights and remedies of the parties hereto shall be cumulative. The transactions contemplated by this Joinder Agreement are unique transactions and any failure on the part of any party to complete the transactions contemplated by this Joinder Agreement on the terms of this Joinder Agreement shall not be fully compensable in damages and the breach or threatened breach of the provisions of this Joinder Agreement would cause the other party hereto irreparable harm. Accordingly, in addition to and not in limitation of any other remedies available to the parties hereto for a breach or threatened breach of this Joinder Agreement each of the parties agrees that, without posting a bond or other undertaking, the parties shall be entitled to seek specific performance of this Joinder Agreement and an injunction restraining any such party from such breach or threatened breach. Each party further agrees that, in the event of any Action for specific performance in respect of such breach or violation, it shall not assert as a defense that a remedy at law would be adequate.

8.9      Interpretation. The words “include,” “includes” and “including” when used herein shall be deemed in each case to be followed by the words “without limitation.” The word “herein” and similar references mean, except where a specific Section or Article reference is expressly indicated, the entire Joinder Agreement rather than any specific Section or Article. The headings contained in this Joinder Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Joinder Agreement. As used herein, all pronouns shall include the masculine, feminine, neuter, singular and plural thereof whenever the context and facts require such construction.

8.10    Severability. If any term or other provision of this Joinder Agreement is invalid, illegal or incapable of being enforced by any rule of Law, or public policy, all other conditions and provisions of this Joinder Agreement shall nevertheless remain in full force and effect.

8.11    Notices. All notices and other communications hereunder shall be in writing and shall be deemed duly given in writing and sufficient if delivered personally or sent by nationally- recognized overnight courier providing evidence of delivery or by registered or certified mail, postage prepaid, return receipt requested, at the following addresses or sent by email:
