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 First Stock Purchase Agreement, the Second 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.

IN WITNESS WHEREOF, the parties have caused this Loan Agreement and Secured Promissory Note to be signed in their respective name by a duly authorized officer as of the 23rd day of April, 2013.
