7.3           Amendment
Provision. The term “Note” and all reference thereto, as used throughout this instrument, shall mean this instrument
as originally executed, or if later amended or supplemented, then as so amended or supplemented.

 

7.4           Assignability.
This Note shall be binding upon the Borrower and its successors and assigns, and shall inure to the benefit of the Holder and its
successors and assigns. The Borrower may not assign its obligations under this Note.

7.5           Cost
of Collection. If default is made in the payment of this Note, Borrower shall pay the Holder hereof reasonable costs of collection,
including reasonable attorneys’ fees.

 

7.6           Governing
Law. This Note is payable at the offices of Holder in California
and shall be governed by and construed in accordance with the laws of
the State of California without regard to conflicts of laws principles
that would result in the application of the substantive laws of another jurisdiction.
Any action brought by either party against the other concerning the transactions contemplated by this Agreement must be brought
only in the civil or state courts of California or in the federal courts located in California, County of Los Angeles. Both parties
and the individual signing this Note on behalf of the Borrower agree to submit to the jurisdiction of such courts. The prevailing
party shall be entitled to recover from the other party its reasonable attorney's fees and costs. In
the event that any provision of this Note is invalid or unenforceable under any applicable statute
or rule of law, then such provision shall be deemed inoperative to the extent that it may conflict therewith and shall be deemed
modified to conform with such statute or rule of law. Any such provision which may prove invalid or unenforceable under any law
shall not affect the validity or unenforceability of any other provision of this Note. Nothing
contained herein shall be deemed or operate to preclude the Holder from bringing suit or taking
other legal action against the Borrower in any other jurisdiction to collect on the Borrower's
obligations to Holder, to realize on any collateral or any
other security for such obligations, or to enforce a judgment or other decision in favor of the Holder.

 

7.7           Maximum
Payments. Notwithstanding any provision to the contrary contained in this Note, the Assignment or any instrument or agreement
executed by Borrower evidencing, having reference to or securing this Note, it is expressly provided that in no case or event shall
the aggregate of any amounts accrued or paid pursuant to this Note which under applicable laws are or may be deemed to constitute
interest ever exceed the maximum nonusurious interest rate permitted by applicable California or federal laws, whichever permit
the higher rate. In this connection, Borrower and Holder stipulate and agree that it is their common and overriding intent to contract
in strict compliance with applicable usury laws. In furtherance thereof, none of the terms of this Note shall ever be construed
to create a contract to pay, as consideration for the use, forbearance or detention of money, interest at a rate in excess of the
maximum rate permitted by applicable laws. Borrower shall never be liable for interest in excess of the maximum rate permitted
by applicable laws. If, for any reason whatever, such interest paid or received during the full term of the applicable indebtedness
produces a rate which exceeds the maximum rate permitted by applicable laws, Holder shall credit against the principal of such
indebtedness (or, if such indebtedness shall have been paid in full, shall refund to the payor of such interest) such portion of
said interest as shall be necessary to cause the interest paid to produce a rate equal to the maximum rate permitted by applicable
laws. All sums paid or agreed to be paid to Holder for the use, forbearance or detention of money shall, to the extent required
to avoid or minimize usury and to the extent permitted by applicable law, be amortized, prorated, allocated and spread throughout
the full term of the applicable indebtedness so that the interest rate thereon does not exceed the maximum nonusurious interest
rate permitted by applicable California or federal laws, whichever permit the higher rate. In the event such interest (whether
designated as interest, service charges, points, or otherwise) does exceed the maximum legal rate, it shall be (a) canceled automatically
to the extent that such interest exceeds the maximum legal rate; (b) if already paid, at the option of Holder, either be rebated
to Borrower or credited on the principal amount of the Note; or if the Note has been prepaid in full, then such excess shall be
rebated to Borrower. The provisions of this Section shall control all agreements, whether now or hereafter existing and whether
written or oral, between Borrower and Holder.

 

7.8           Non-Business
Days. Whenever any payment or any action to be made shall be due on a Saturday, Sunday
or a public holiday under the laws of the State of California, such
payment may be due or action shall be required on the next succeeding business day and, for such payment, such next succeeding
day shall be included in the calculation of the amount of accrued interest payable on such date.

7.9           Redemption.
This Note may not be redeemed or called without the consent of the Holder except
as described in this Note.

 

7.10         Expenses.
Borrower and Holder shall each pay their respective legal and
other fees and expenses associated with all aspects of the transaction contemplated by this Note;
provided, however, that Borrower shall reimburse, or cause Cellteck to
reimburse, Holder for its legal fees and expenses in connection with the transactions contemplated
hereby up to $25,000. Such reimbursement shall be payable upon maturity of this Note.

 

7.11         Judicial
Reference. Borrower, and, by its acceptance of this Note,
Holder, acknowledge and agree that any controversy or claim arising out of or relating to this
Note or any of the Guaranty, the Assignment, the Stock Purchase Agreement,
the Lock-up/Leak-Out Agreement between Holder and Cellteck entered into concurrently herewith, the Compliance/Oversight Agreement
between Holder and Borrower entered into concurrently herewith, or breach hereof or thereof, shall be resolved by a referee appointed
by the Superior Court for the County of Los Angeles, California (“Superior Court”)
in accordance with the provisions of Section 638 et seq. of the California Code of Civil Procedure.
In this regard, Borrower and Holder agree that in the event
they are unable agree upon a resolution to any such controversy or claim, either party shall have the right to serve a written
demand for judicial reference of such claim or controversy on the other party. The two parties shall then negotiate in good faith
for a mutually acceptable referee. In the event that parties have not agreed upon a referee within ten (10) business days
after written demand for such reference has been made, each party shall submit to the Superior
Court the names of up to three nominees for appointment as referee, in accordance with the provisions
of Section 640 of the California Code of Civil Procedure. The referee, once agreed upon by the parties or appointed by the Superior
Court, shall have full and complete authority to hear and determine any and all of the issues in an
action or proceeding, whether of fact or of law, and to report a statement of decision. In connection with such reference procedure,
the parties shall have all rights and powers afforded to a civil litigant in the Superior Court,
including the ability to conduct full discovery and obtain responses under oath. The referee shall be governed by the rules of
civil procedure for actions filed in California superior courts as set forth in the California Code of Civil Procedure, except
to the extent the parties stipulate the referee may deviate therefrom. The parties shall evenly divide the cost of the referee’s
fees. The referee shall have the power, as part of any award, to include these fees as an element of recovery. The decision of
the referee upon the whole issue shall stand as the decision of the Superior Court, and upon
the filing of the statement of decision with the clerk of the Superior Court, judgment may be
entered thereon in the same manner as if the action had been tried by the Superior Court. Notwithstanding
the rights to appeal set forth in Section 645 of the California Code of Civil Procedure, the parties agree that the referee’s
award shall be considered final, and not subject to appeal or collateral attack.
