6.    Conversion;
Change of Control.


 


(a)   Automatic
Conversion upon a Qualified Equity Financing. In the event Borrower Parent consummates, prior to the Maturity Date, the Initial
Public Offering or any other Qualified Equity Financing, thenthe Note Balance shall automatically convert into:


 


(i)          
that number of fully paid and nonassessable shares of the Borrower Parent’s equity securities of the same class issued under
the Qualified Equity Financing (“Conversion Shares”) equal to the quotient obtained by dividing (x) the Note
Balance by (y) the applicable Note Conversion Price (as defined in Section 9, below); and


 


(ii)           a stock
purchase warrant (the “Warrant”), which shall be substantially in the form of Exhibit A attached
hereto, to purchase that number of shares of the Borrower Parent’s Common Stock equal to the number of Conversion Shares
(the “Warrant Shares”) for the applicable Warrant Exercise Price (as defined in Section 9, below).


 


(b)          Automatic
Conversion Procedure. The issuance of Conversion Securities upon conversion of the Note Balance shall be upon the terms and
subject to the conditions no less favorable than the terms and conditions of the Qualified Equity Financing, except that Conversion
Shares issued in the Initial Public Offering will be restricted common stock, and not publicly traded common stock. The Holder
agrees to deliver the original of this Note (or a notice to the effect that the original Note has been lost, stolen or destroyed
and an agreement mutually and reasonably acceptable to Borrower Parent and the Holder whereby the Holder agrees to indemnify Borrower
Parent from any loss incurred by it in connection with this Note) at the closing of the Qualified Equity Financing for cancellation;
provided, however, that upon satisfaction of the conditions set forth in this Section 6(b), this Note shall
be deemed converted and of no further force and effect, whether or not it is delivered for cancellation as set forth in this sentence.


 


(c)    Optional
Conversion. 


 


(i)          Non-Qualified
Equity Financing. Upon the consummation of an equity financing that is not a Qualified Equity Financing or a Permitted Issuance
(such financing, a “Non-Qualified Equity Financing”), all or a portion of the Note Balance shall be convertible
at the option of the Holder into:


 




    	- 4 -



    	 



    

 


(1)         that
number of fully paid and nonassessable shares of the equity security sold by Borrower Parent in such Non-Qualified Equity Financing
(“Non-Qualified Financing Shares”) determined by dividing (x) the Note Balance by (y) the applicable Note Conversion
Price.


 


(2)         a
Warrant to purchase the same number of shares of Common Stock as the Non-Qualified Financing Shares (also, the “Warrant
Shares”) for the lesser of (a) applicable Warrant Exercise Price, or (b) the exercise price of any warrants issued in
the Non-Qualified Equity Financing.


 


Borrower Parent shall give Holder at least
30-days’ prior written notice of any contemplated Non-Qualified Equity Financing. As a condition precedent (which may be
waived by Borrower Parent) to issuance of the Non-Qualified Financing Shares and the Warrant, the Holder will be required to execute
the transaction documents prepared in connection with the Non-Qualified Equity Financing; provided, however, that such transaction
documents are on terms no less favorable with respect to such Non-Qualified Financing Stock than the terms of the transaction documents
entered into with all other purchasers of the Non-Qualified Financing Stock.


 


(ii)         Change
of Control. Upon notice of a Change of Control of Borrower Parent that is not a Permitted Issuance, all or a portion of the
Note Balance shall be convertible at the option of the Holder into that number of fully paid and nonassessable shares of the equity
security sold by Borrower Parent in such Change of Control (“Change of Control Shares”) determined by dividing
(x) the Note Balance by (y) the applicable Note Conversion Price. In addition, Borrower Parent shall issue a Warrant to purchase
the same number of shares of Common Stock as the Change of Control Shares (also, the “Warrant Shares”) for the
lesser of (a) applicable Warrant Exercise Price, or (b) the exercise price of any warrants issued in the Change of Control transaction.
The Borrowers shall provide Holder notice of any Change of Control in accordance with Section 10(c) below.


 


(d)          Optional
Conversion Procedure.  Before the Holder shall be entitled to convert this Note into shares of Borrower Parent’s
stock pursuant to Section 6(c)(ii), it shall surrender this Note, duly endorsed, at the office of Borrower Parent and shall
give written notice to Borrower Parent at its principal corporate office, of the election to convert the same pursuant to Section
6(c)(ii), and shall state therein the amount of the unpaid principal and accrued interest of this Note, as applicable, to be
converted and the name or names in which the Convertible Securities are to be issued. Borrower Parent shall, as soon as practicable
thereafter, issue and deliver to the Holder a certificate or certificates for the Non-Qualified Financing Shares or the Change
of Control Shares, as applicable (bearing such legends as are required by the applicable stock purchase agreement and applicable
state and federal securities laws in the opinion of counsel to Borrower Parent), together with a replacement Note (if any principal
amount is not converted) and any other securities and property to which Holder is entitled upon such conversion under the terms
of this Note, including a check payable to the Holder for any cash amounts payable as described in Section 6(f). If
Holder elects to exercise its option to convert pursuant to Section 6(c)(i), such conversion shall be deemed to have been
made upon the consummation of the Non-Qualified Equity Financing and the Person or Persons entitled to receive the Non-Qualified
Financing Shares shall be treated as the record investor(s) as of such time.


 


(e)          Issuance
to Members of Holder. Holder shall have the option, at its sole discretion, to cause the Borrowers to issue the Conversion
Securities directly to its members in accordance with their membership percentages, subject to the requirements of the Securities
Purchase Agreement. Any such members shall have the same rights and obligations as Holder under this Note.

Shares; Interest. No fractional shares shall be issued upon conversion of this Note. In lieu of Borrower Parent issuing any
fractional shares to the Holder upon the conversion of this Note, Borrower Parent shall pay to Holder an amount equal to the product
obtained by multiplying the applicable conversion price by the fraction of a share not issued pursuant to the previous sentence.
In addition, to the extent not converted into shares of capital stock, Borrower Parent shall pay to Holder any interest accrued
on the amount converted and on the amount to be paid to Borrower Parent pursuant to the previous sentence.


 


(g)          Deliver
of Note; Lost Note Indemnification. At the closing of any optional conversion under this Section 6(c) for cancellation,
the Holder agrees to deliver (i) the original of this Note, or (ii) a notice to the effect that the original Note has been lost,
stolen or destroyed and an agreement mutually and reasonably acceptable to Borrower Parent and Holder whereby Holder agrees to
indemnify Borrower Parent against the claims of any Persons claiming an interest in this Note after conversion and issuance of
the Conversion Securities to the Holder.


 


(h)          Effect
of Conversion. Upon issuance of the Conversion Securities, (a) this Note automatically shall be deemed converted, fully paid,
cancelled, and (b) the Borrowers shall be forever released from all its obligations and liabilities under this Note and this Note
shall be deemed of no further force or effect, whether or not the original of this Note has been delivered to Borrower Parent for
cancellation.
