CONVERTIBLE PROMISSORY NOTE

[$] [Date]

FOR VALUE RECEIVED, Accelsius Holdings LLC, a Delaware limited liability company (the “Company”), hereby promises to pay to [Name of Holder] (“Holder”), the principal sum of [$]. Interest shall accrue from the date of this Convertible Promissory Note (this “Note”) on the unpaid principal amount at a rate equal to eight percent per annum (the “Interest Rate”). The Interest Rate shall be calculated on the basis of the actual number of days elapsed over a year of 365 days. This Note is one of a series of Convertible Promissory Notes being issued pursuant to the Series I Convertible Note Purchase Agreement, dated as of August 18, 2022 (the “Purchase Agreement”), by and among the Company, Holder and the other parties thereto.

This Note is subject to the following terms and conditions:

1.Definitions. For purposes of this Note, the following terms shall have the meanings set forth in this Section 1. Any other capitalized term used herein but not defined herein shall have the meanings ascribed to such term in the Purchase Agreement.

“Change in Control Transaction” shall mean (a) a merger of the Company with or into another entity, if, after such merger, the holders of a majority of the Company’s voting securities immediately prior to such merger do not hold a majority of the voting securities of the successor entity; (b) the sale by the Company of all or substantially all of its assets; or (c) any transaction in which more than 50% of the voting securities of the Company are transferred to any person who is not a equity holder on the date of the Initial Closing, in all cases, other than a transaction (or series of related transactions) which is primarily for the purpose of financing or reorganizing the Company.

“Class A Units” means the Class A Units of the Company.

“Next Equity Securities” means the type of equity securities of the Company issued in a Qualified Financing.

“Non-Qualified Financing Equity Securities” means the type of equity securities of the Company issued in a Non-Qualified Financing (as defined below).

“Proceeds” means cash and other assets (including without limitation equity consideration) that are proceeds from a Change in Control Transaction and legally available for distribution.

“Qualified Financing” means the sale by the Company of equity securities in a bona fide financing or bona fide financings following the date of this Agreement resulting in gross proceeds to the Company, in the aggregate, of at least $2,000,000 (not including, for purposes of such calculation, the conversion of any Convertible Notes into Next Equity Securities or the conversion of any other convertible securities), which is primarily for investment purposes and not made primarily in connection with a strategic arrangement.

“Units” means the Class A Units and the Class C Units of the Company.

2. Maturity.

(a)Unless converted, exchanged or otherwise paid pursuant to Section 3, the principal amount then outstanding and any accrued but unpaid interest under this Note shall be due and payable on the earlier of (i) August 18, 2025 or (ii) the consummation of a Change in Control Transaction (such earlier date, the “Maturity Date”); provided, however, that, notwithstanding the foregoing, the Maturity Date may be extended with the written consent of the Company and the Requisite Majority.

3. Conversion/Exchange.

(a)Automatic Conversion. Upon the consummation of a Qualified Financing prior to the Maturity Date, the principal amount then outstanding and any accrued but unpaid interest under this Note will automatically convert into Next Equity Securities at a conversion price equal to the lesser of (a) 80% of the per unit price paid by the investors purchasing Next Equity Securities in the Qualified Financing or (b) the quotient of $200,000,000 divided by the aggregate number of outstanding Units as of immediately prior to the initial closing of the Next Equity Securities (assuming full conversion or exercise of all convertible and exercisable securities, including any new options issued with the Qualified Financing, then outstanding other than the Notes), and otherwise on the same terms and conditions as given to the investors purchasing Next Equity Securities in the Qualified Financing.

(b)Optional Conversion upon Closing of a Non-Qualified Financing. Upon the consummation of the sale by the Company of equity securities in a bona fide financing or bona fide financings following the date of this Agreement, but prior to the Maturity Date, which is not a Qualified Financing (a “Non-Qualified Financing”), then, if the Holder so elects in its sole discretion, the principal amount then outstanding and any accrued but unpaid interest under this Note will convert into Non-Qualified Financing Equity Securities at a conversion price equal to the lesser of (a) 80% of the per unit price paid by the investors purchasing Non-Qualified Financing Equity Securities in a Non-Qualified Financing, or (b) the quotient of $200,000,000 divided by the aggregate number of outstanding Units as of immediately prior to the initial closing of the Non- Qualified Financing (assuming full conversion or exercise of all convertible and exercisable securities, including any new options issued with the Non-Qualified Financing, then outstanding other than the Notes), and otherwise on the same terms and conditions as given to the investors purchasing Non-Qualified Financing Equity Securities in the Non-Qualified Financing.

(c)Change in Control Transaction. Upon the consummation of a Change in Control Transaction prior to August 18, 2025, Holder shall be entitled to receive a portion of the Proceeds, due and payable to Holder immediately prior to, or concurrent with, the consummation of such Change in Control Transaction, equal to the greater of (i) 1.5 times the principal amount then outstanding and any accrued but unpaid interest under this Note on the Maturity Date or (ii) the amount payable on the number of Class A Units equal to the principal amount then outstanding and any accrued but unpaid interest under this Note on the Maturity Date divided by a price per unit equal to the lesser of (A) 80% of the per unit price paid by the acquiring party or parties to a Change In Control Transaction (assuming full conversion or exercise of all convertible and exercisable securities then outstanding other than the Notes) or (B) the quotient of $200,000,000 divided by the aggregate number of outstanding Units as of immediately prior to the initial closing of the Change in Control Transaction (assuming full conversion or exercise of all convertible and exercisable securities then outstanding other than the Notes).

(d)Optional Conversion upon Maturity. Subject to Sections 3(a), (b) and (c), if this Note remains outstanding on or after the Maturity Date, then, if the Holder so elects in its sole discretion, the principal amount then outstanding and any accrued but unpaid interest under this Note will convert into Class A Units at a conversion price equal to the lesser of (a) 80% of the fair market value per unit of the Class A Units, as determined by the Board (as defined in the LLC Agreement), in its sole discretion acting in good faith, or (b) the quotient of $200,000,000 divided by the aggregate number of then-outstanding Units (assuming full conversion or exercise of all convertible and exercisable securities then outstanding other than the Notes), and otherwise on the same terms and conditions as the holders of Class A Units are entitled.

(e)Mechanics of Conversion or Exchange. No fractional units of the Company will be issued upon the conversion of this Note. In lieu of any fractional unit to which Holder would otherwise be entitled, the Company will pay to Holder, in cash, the amount of the unconverted principal amount and any accrued but unpaid interest then outstanding under this Note that would otherwise be converted into such fractional unit. Upon conversion of this Note pursuant to this Section 3, Holder shall surrender this Note, duly endorsed, at the principal offices of the Company or any transfer agent of the Company. At its expense, the Company will, as soon as practicable thereafter, issue and deliver to Holder a certificate or certificates for the number of units to which Holder is entitled upon such conversion, together with any other securities and property to which Holder is entitled upon such conversion under the terms of this Note, including a check payable to Holder for any cash amounts payable as described herein. Upon conversion or repayment of this Note, the Company will be forever released from all of its obligations and liabilities under this Note with regard to that portion of the principal amount and accrued interest being converted including without limitation the obligation to pay such portion of the principal amount.

4. Payment; Prepayment.

(a)All payments under this Note shall be made in lawful money of the United States of America to such account of Holder as Holder may from time to time designate in writing to the Company. Payment shall be credited first to the accrued interest then due and payable and the remainder applied to the principal amount.

-3-

(b)The Company may prepay this Note without penalty or premium with the prior written consent of the Requisite Majority; provided that all Convertible Notes then outstanding shall be paid on a pro rata basis.

5.Event of Default. If there shall be any Event of Default (as defined below), at the option and upon the declaration of Holder and upon written notice to the Company, this Note shall accelerate and all principal and accrued interest shall become due and payable. The occurrence of any one or more of the following shall constitute an “Event of Default”:

(a)the Company fails to pay timely any of the principal amount or other amounts due under this Note on the date the same becomes due and payable;

(b)the Company fails to comply with any material provision of this Note or the Purchase Agreement, which failure is not cured within 30 days of Holder’s written notice of such failure;

(c)the Company files any petition or action for relief under any bankruptcy, reorganization, insolvency or moratorium law or any other law for the relief of, or relating to, debtors, now or hereafter in effect, or makes any assignment for the benefit of creditors or takes any company action in furtherance of any of the foregoing; or

(d)an involuntary petition is filed against the Company (unless such petition is dismissed or discharged within 90 days) under any bankruptcy statute now or hereafter in effect, or a custodian, receiver, trustee, or assignee for the benefit of creditors (or other similar official) is appointed to take possession, custody or control of any property of the Company.

6. No Security. This Note is a general unsecured obligation of the Company.

7.Governing Law. This Note shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of law.

8.Amendment. Neither this Note nor any term hereof may be amended, waived, discharged or terminated other than by a written instrument referencing this Agreement and signed by the Company and the Requisite Majority; provided, however, that, notwithstanding the foregoing, this Note may not be amended, and the observance of any term of this Note may not be waived, without the written consent of Holder, unless such amendment or waiver applies to the Convertible Notes held by all holders and does not have a disproportionate adverse effect on Holder.

9.Transferability. This Note, and any interest in the rights and obligations of Holder hereunder, may not be assigned by Holder, without the prior written consent of the Company. The Company may not assign this Note or its rights or obligations under this Note without the Requisite Majority’s consent.

10.Severability. If any provision of this Note becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, portions of such provision, or such provision in its entirety, to the extent necessary, shall be severed from this Note, and such court will replace such illegal, void or unenforceable provision of this Note with a valid and enforceable provision that will achieve, to the extent possible, the same economic, business and other purposes of the illegal, void or unenforceable provision. The balance of this Note shall be enforceable in accordance with its terms.

11.Counterparts. This Note may be executed in any number of counterparts, each of which shall be enforceable against the parties actually executing such counterparts, and all of which together shall constitute one instrument. Counterparts may be delivered via electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.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.

12.Purchase Agreement. This Note is one of a series of Convertible Notes being issued pursuant to the Purchase Agreement and is entitled to all of the benefits, and subject to all of the limitations, provided in the Purchase Agreement, which are hereby incorporated herein by reference as though set forth herein in their entirety.
