Section 2. Conditions to Lending. 

The obligation of the Lender to make the Loan or any Advance thereunder available to the Borrower under this Note shall be expressly subject
to the following conditions precedent: 
 (a) The Note. The Borrower shall have duly executed and delivered this Note
to the Lender. 
 (b) Drawdown Notice. The Lender shall have received a Drawdown Notice in accordance with the terms
of Section 3. 
 (c) No Event of Default. No Event of Default shall have occurred which remains outstanding and
uncured. 







 Section 3. The Loan. 

(a) Availability. During the Availability Period, the Lender shall make the Loan available to the Borrower in one or
more advances (each, an “Advance”), for the purpose of funding the working capital needs of the Borrower. Each Advance shall be in a minimum amount of One Million Dollars ($1,000,000). 

(b) Drawdown Notice. The Borrower shall during the Availability Period, in respect of any Advance, provide the Lender

(c) Evidence of Drawdown. The Lender shall endorse the amount and the date of the making of any Advance and any
prepayment or payment of principal hereunder on the grid annexed hereto and made a part hereof, which endorsement shall constitute prima facie evidence of the accuracy of the information so endorsed; provided, however,

(d) Loan Maturity. The Loan shall mature, and the principal amount thereof shall become immediately due and payable
(together with default interest accrued thereon, if any), on the Termination Date. If this Note or any payment required to be made hereunder becomes due and payable on a day which is not a Business Day, the due date thereof shall be extended until
the next following Business Day and interest shall be payable during such extension at the rate applicable immediately prior thereto. 

Section 4. Principal and Interest. 

(a) Termination Date Payment. The outstanding principal balance of the Loan and any outstanding fees, expenses or
charges, shall be payable on the Termination Date. 
 (b) Default Interest. The Borrower shall pay interest at a rate
equal to two percent (2%) per annum from (and including) the relevant date until the date of actual payment (as well after as before judgment) on any amount payable by the Borrower under this Note which the Lender does not receive on or before
the Termination Date or, if payable on demand, the date on which demand is served or, if immediately due and payable under this Note, the date on which it became immediately due and payable. 







 (c) Usury Modification. It is the intent of the parties that the rate of
interest and other charges to the Borrower under this Note shall be lawful; therefore, if for any reason the interest or other charges payable under this Note are found by a court of competent jurisdiction, in a final determination, to exceed the
limit which the Lender may lawfully charge the Borrower, then the obligation to pay interest and other charges shall automatically be reduced to such limit and, if any amount in excess of such limit shall have been paid, then such amount shall be
refunded to the Borrower. 
 Section 5. Optional Prepayments.  

The Borrower may prepay the Loan in whole or in part on any Business Day without penalty by paying the portion of the Loan to be prepaid
together with interest accrued thereon to the date of prepayment (the “Prepayment Date”).

in writing to the Borrower without reduction by reason of any set-off or counterclaim.

All payments in respect of or relating to this Note by the Borrower shall be made without withholding or deduction for, or on account of, any
present or future taxes, duties, assessments or governmental charges of whatever nature imposed or levied by or on behalf of any tax jurisdiction unless the withholding or deduction is required by law. If withholding or deduction is required by law,
the Borrower shall pay such additional amounts as are necessary in order that the net amounts received by the Lender after the withholding or deduction shall equal the respective amounts which would have been receivable in respect of or relating to
this Note in the absence of the withholding or deduction.

Applicable Laws; and

(e) the Borrower shall commence a voluntary case under any applicable bankruptcy, insolvency or other similar law now or
hereafter in effect, or consent to the entry of an order for relief in an involuntary case under any such law, or consent to the appointment or taking possession by a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar
official) of the Borrower or for any substantial part of the property of the Borrower, or the Borrower shall make any general assignment for the benefit of creditors; or

If an Event of Default described in (d), (e) or (f) above shall occur, the unpaid principal and accrued interest on the Loan shall
become immediately due and payable without any declaration or other act on the part of the Lender. Immediately upon the occurrence of any Event of Default described in (d), (e) or (f) above, or upon failure to pay this Note in full on the
Termination Date, the Lender, without any notice to the Borrower, which notice is expressly waived by the Borrower, may proceed to protect, enforce, exercise and pursue any and all rights and remedies available to the Lender under this Note and any
other agreement or instrument, and any and all rights and remedies available to the Lender at law or in equity. 
 If any Event of Default
described in clauses (a) through (c) shall occur for any reason, whether voluntary or involuntary, and be continuing, the Lender may by notice to the Borrower declare all or any portion of the unpaid principal amount of the Loan to be due

and do such other acts and things as the Lender may reasonably request in order fully to effect the purposes of this Note and to protect and preserve the priority and validity of the security interests granted hereunder. 

Section 13. Powers and Remedies Cumulative; Delay or Omission Not Waiver of Event of Default.  

No right or remedy herein conferred upon or reserved to the Lender is intended to be exclusive of any other right or remedy, and every right
and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 
 No delay or
omission of the Lender to exercise any right or power accruing upon any Event of Default occurring and continuing as aforesaid shall impair any such right or power or shall be construed to be a waiver of any Event of Default or an acquiescence
therein; and every power and remedy given by this Note or by law may be exercised from time to time, and as often as shall be deemed expedient, by the Lender.
