1. Payment; Prepayment; Failure to Register.

1.1. Payment. All payments owing hereunder shall be in lawful money of the United States of America or Conversion Shares (as defined below), as provided for herein, and delivered to Lender at the address or bank account furnished to Borrower for that purpose. All payments shall be applied first to (a) costs of collection, if any, then to (b) fees and charges, if any, then to (c) accrued and unpaid interest, and thereafter, to (d) principal.

1.2. Prepayment. Notwithstanding the foregoing, Borrower shall have the right to prepay all or any portion of the Outstanding Balance (less such portion of the Outstanding Balance for which Borrower has received a Redemption Notice (as defined below) from Lender where the applicable Conversion Shares have not yet been delivered). If Borrower exercises its right to prepay this Note, Borrower shall make payment to Lender of an amount in cash equal to 105% multiplied by the portion of the Outstanding Balance Borrower elects to prepay.

1.3. Failure to Register. During the period beginning on the date that is forty-five (45) days from the Purchase Price Date and ending on the date that is six (6) months following the Purchase Price Date, the Outstanding Balance will automatically be increased by one-half percent (0.5%) for each calendar month where Borrower does not have an effective registration statement available for Lender to sell Conversion Shares under.

2. Security. This Note shall be unsecured.

3. Redemptions.

3.1. Redemption Conversion Price. Subject to the adjustments set forth herein, the conversion price for each Redemption Conversion shall be the Redemption Conversion Price.

3.2. Redemption Conversions. Beginning on the date that is forty-five (45) days from the Purchase Price Date, Lender shall have the right, exercisable at any time in its sole and absolute discretion, to redeem all or any portion of the Note (such amount, the “Redemption Amount”), subject to the Maximum Monthly Redemption Amount, by providing Borrower with a notice substantially in the form attached hereto as Exhibit A (each, a “Redemption Notice”, and each date on which Lender delivers a Redemption Notice, a “Redemption Date”). For the avoidance of doubt, Lender may submit to Borrower one (1) or more Redemption Notices in any given calendar month; provided that the aggregate Redemption Amounts in such calendar month do not exceed the Maximum Monthly Redemption Amount. Payments of each Redemption Amount may be made, at the Borrower’s election, (a) in cash, or (b) by converting such Redemption Amount into registered Common Shares (each, a “Redemption Conversion”) for the period beginning on the date that is forty-five (45) days from the Purchase Price Date and ending on the date that is six (6) months from the Purchase Price Date and in registered or unregistered Common Shares thereafter per the following formula: the number of Conversion Shares equals the portion of the applicable Redemption Amount being converted divided by the Redemption Conversion Price (the “Conversion Shares”), or (c) by any combination of the foregoing, so long as the cash is delivered to Lender on the third (3^rd) Trading Day immediately following the applicable Redemption Date and the Redemption Conversion Shares are delivered to Lender on or before the applicable Delivery Date (as defined below). Notwithstanding the foregoing, Borrower will not be entitled to elect a Redemption Conversion with respect to any portion of any applicable Redemption Amount and shall be required to pay the Redemption Amount in cash, if: (a) on the applicable Redemption Date there is an Equity Conditions Failure, and such failure is not waived in writing by Lender, or (b) the Redemption Conversion Price is below the Floor Price. Notwithstanding that failure to repay this Note in full by the Maturity Date is an Event of Default (as defined below), the Redemption Dates shall continue after the Maturity Date pursuant to this Section 3.2 until the Outstanding Balance is repaid in full.

3.3. Allocation of Redemption Amounts. Following its receipt of a Redemption Notice, Borrower may either ratify Lender’s proposed allocation in the applicable Redemption Notice or elect to change the allocation by written notice to Lender by email or fax within two (2) Trading Days of its receipt of such Redemption Notice, so long as the sum of the cash payments and the amount of Redemption Conversions equal the applicable Redemption Amount. If Borrower fails to notify Lender of its election to change the allocation prior to the deadline set forth in the previous sentence, it shall be deemed to have ratified and accepted the allocation set forth in the applicable Redemption Notice prepared by Lender. Borrower acknowledges and agrees that the amounts and calculations set forth thereon are subject to correction or adjustment because of error, mistake, or any adjustment resulting from an Event of Default or other adjustment permitted under the Transaction Documents (an “Adjustment”). Furthermore, no error or mistake in the preparation of such notices, or failure to apply any Adjustment that could have been applied prior to the preparation of a Redemption Notice may be deemed a waiver of Lender’s right to enforce the terms of any Note, even if such error, mistake, or failure to include an Adjustment arises from Lender’s own calculation. Borrower shall deliver the Redemption Conversion Shares from any Redemption Conversion to Lender in accordance with Section 7 below on or before each applicable Delivery Date.

4. Trigger Events, Defaults and Remedies.

4.1. Trigger Events.

4.2. Trigger Event Remedies. At any time following the occurrence of any Trigger Event, Lender may, at its option, increase the Outstanding Balance by applying the Trigger Effect (subject to the limitation set forth below).

4.3. Defaults. At any time following the occurrence and during the continuance of a Trigger Event, Lender may, at its option, send written notice to Borrower demanding that Borrower cure the Trigger Event within ten (10) Trading Days following the date of receipt of such written notice by Borrower. If Borrower fails to cure the Trigger Event within the required ten (10) Trading Day cure period after receipt of such written notice by Borrower, Lender may, at its option, send written notice to the Borrower that the Trigger Event, as of the date of such notice, become an event of default hereunder (each, an “Event of Default”).

4.4. Default Remedies. At any time and from time to time following the occurrence of any Event of Default, Lender may accelerate this Note by written notice to Borrower, with the Outstanding Balance becoming immediately due and payable in cash at the Mandatory Default Amount. Notwithstanding the foregoing, upon the occurrence of any Trigger Event described in clauses (b) – (f) of Section 4.1, an Event of Default will be deemed to have occurred and the Outstanding Balance as of the date of the occurrence of such Trigger Event shall become immediately and automatically due and payable in cash at the Mandatory Default Amount, without any written notice required by Lender for the Trigger Event to become an Event of Default. At any time following the occurrence of any Event of Default, upon written notice given by Lender to Borrower, interest shall accrue on the Outstanding Balance beginning on the date the applicable Event of Default occurred at an interest rate equal to the lesser of fifteen percent (15%) per annum simple interest or the maximum rate permitted under applicable law (“Default Interest”). For the avoidance of doubt, Lender may continue making Redemption Conversions at any time following an Event of Default until such time as the Outstanding Balance is paid in full, subject to the limitation set forth in Sections 3.2 (Maximum Monthly Redemption Amount limitation) and 9 (Ownership Limitation) hereof. In connection with acceleration described herein, Lender need not provide, and Borrower hereby waives, any presentment, demand, protest or other notice of any kind, and Lender may immediately and without expiration of any grace period enforce any and all of its rights and remedies hereunder and all other remedies available to it under applicable law. Such acceleration may be rescinded and annulled by Lender at any time prior to payment hereunder and Lender shall have all rights as a holder of the Note until such time, if any, as Lender receives full payment pursuant to this Section 4.2. No such rescission or annulment shall affect any subsequent Trigger Event or Event of Default or impair any right consequent thereon. Nothing herein shall limit Lender’s right to pursue any other remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to Borrower’s failure to timely deliver Conversion Shares upon Conversion of the Note as required pursuant to the terms hereof.

3

5. Unconditional Obligation; No Offset. Borrower acknowledges that this Note is an unconditional, valid, binding and enforceable obligation of Borrower not subject to offset, deduction or counterclaim of any kind. Borrower hereby waives any rights of offset it now has or may have hereafter against Lender, its successors and assigns, and agrees to make the payments or Conversions called for herein in accordance with the terms of this Note.

6. Waiver. No waiver of any provision of this Note shall be effective unless it is in the form of a writing signed by the party granting the waiver. No waiver of any provision or consent to any prohibited action shall constitute a waiver of any other provision or consent to any other prohibited action, whether or not similar. No waiver or consent shall constitute a continuing waiver or consent or commit a party to provide a waiver or consent in the future except to the extent specifically set forth in writing.

7. Method of Conversion Share Delivery. On or before the close of business on the third (3^rd) Trading Day following each Redemption Date (the “Delivery Date”), Borrower shall, provided it is DWAC Eligible at such time and such Conversion Shares are eligible for delivery via DWAC, deliver or cause its transfer agent to deliver the applicable Conversion Shares electronically via DWAC to the account designated by Lender in the applicable Redemption Notice. If Borrower is not DWAC Eligible or such Conversion Shares are not eligible for delivery via DWAC, it shall deliver to Lender or its broker (as designated in the Redemption Notice), via reputable overnight courier, a certificate representing the number of Common Shares equal to the number of Conversion Shares to which Lender shall be entitled, registered in the name of Lender or its designee. For the avoidance of doubt, Borrower has not met its obligation to deliver Conversion Shares by the Delivery Date unless Lender or its broker, as applicable, has actually received the certificate representing the applicable Conversion Shares no later than the close of business on the relevant Delivery Date pursuant to the terms set forth above. Moreover, and notwithstanding anything to the contrary herein or in any other Transaction Document, in the event Borrower or its transfer agent refuses to deliver any Conversion Shares without a restrictive securities legend to Lender on grounds that such issuance is in violation of Rule 144 under the Securities Act of 1933, as amended (“Rule 144”), Borrower shall deliver or cause its transfer agent to deliver the applicable Conversion Shares to Lender with a restricted securities legend, but otherwise in accordance with the provisions of this Section 7. In conjunction therewith, Borrower will also deliver to Lender a written explanation from its counsel or its transfer agent’s counsel opining as to why the issuance of the applicable Conversion Shares violates Rule 144.

4

8. Conversion Delays. If Borrower fails to deliver Conversion Shares in accordance with the timeframe stated in Section 7, Lender may at any time prior to receiving the applicable Conversion Shares rescind in whole or in part such Conversion, with a corresponding increase to the Outstanding Balance (any returned amount will tack back to the Purchase Price Date for purposes of determining the holding period under Rule 144). In addition, for each Conversion, in the event that Conversion Shares are not delivered by the Delivery Date, a late fee equal to 2% of the applicable Conversion Share Value rounded to the nearest multiple of $100.00 but with a floor of $500.00 per day (but in any event the cumulative amount of such late fees for each Conversion shall not exceed 150% of the applicable Conversion Share Value) will be assessed for each day after the Delivery Date until Conversion Share delivery is made; and such late fees will be added to the Outstanding Balance (such fees, the “Conversion Delay Late Fees”).

9. Ownership Limitation. Notwithstanding anything to the contrary contained in this Note or the other Transaction Documents, Borrower shall not effect any conversion of this Note to the extent that after giving effect to such conversion would cause Lender (together with its affiliates) to beneficially own a number of shares exceeding 4.99% of the number of Common Shares outstanding on such date (including for such purpose the Common Shares issuable upon such issuance) (the “Maximum Percentage”). For purposes of this section, beneficial ownership of Common Shares will be determined pursuant to Section 13(d) of the 1934 Act. Notwithstanding the forgoing, the term “4.99%” above shall be replaced with “9.99%” at such time as the Market Capitalization is less than $15,000,000.00. Notwithstanding any other provision contained herein, if the term “4.99%” is replaced with “9.99%” pursuant to the preceding sentence, such increase to “9.99%” shall remain at 9.99% until increased, decreased or waived by Lender as set forth below. By written notice to Borrower, Lender may increase, decrease or waive the Maximum Percentage as to itself but any such waiver will not be effective until the 61st day after delivery thereof. The foregoing 61-day notice requirement is enforceable, unconditional and non-waivable and shall apply to all affiliates and assigns of Lender.

10. Opinion of Counsel. In the event that an opinion of counsel is needed for conversion of this Note, Lender has the right to have any such opinion provided by its counsel.

11. Governing Law; Venue. This Note shall be construed and enforced in accordance with, and all questions concerning the construction, validity, interpretation and performance of this Note shall be governed by, the internal laws of the State of Utah, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Utah or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Utah. The provisions set forth in the Purchase Agreement to determine the proper venue for any disputes are incorporated herein by this reference.

12. Arbitration of Disputes. By its issuance or acceptance of this Note, each party agrees to be bound by the Arbitration Provisions (as defined in the Purchase Agreement) set forth as an exhibit to the Purchase Agreement.

13. Cancellation. After repayment or conversion of the entire Outstanding Balance, this Note shall be deemed paid in full, shall automatically be deemed canceled, and shall not be reissued.

14. Amendments. The prior written consent of both parties hereto shall be required for any change or amendment to this Note.

5

15. Assignments. Borrower may not assign this Note without the prior written consent of Lender. This Note and any Common Shares issued upon conversion of this Note may be offered, sold, assigned or transferred by Lender without the consent of Borrower, so long as such transfer is in accordance with applicable federal and state securities laws.

16. Notices. Whenever notice is required to be given under this Note, unless otherwise provided herein, such notice shall be given in accordance with the subsection of the Purchase Agreement titled “Notices.”

17. Liquidated Damages. Lender and Borrower agree that in the event Borrower fails to comply with any of the terms or provisions of this Note, Lender’s damages would be uncertain and difficult (if not impossible) to accurately estimate because of the parties’ inability to predict future interest rates, future share prices, future trading volumes and other relevant factors. Accordingly, Lender and Borrower agree that any fees, balance adjustments, Default Interest or other charges assessed under this Note are not penalties but instead are intended by the parties to be, and shall be deemed, liquidated damages (under Lender’s and Borrower’s expectations that any such liquidated damages will tack back to the Purchase Price Date for purposes of determining the holding period under Rule 144). Therefore, no additional penalty claims, lost profits or liquidated damages shall be claimed in excess of agreed liquidated damage amounts under this Note.

18. Severability. If any part of this Note is construed to be in violation of any law, such part shall be modified to achieve the objective of Borrower and Lender to the fullest extent permitted by law and the balance of this Note shall remain in full force and effect.
