SECURED CONVERTIBLE PROMISSORY NOTE

FOR VALUE RECEIVED, CYTODYN INC., a Delaware corporation (“Borrower”), promises to pay to ILIAD RESEARCH AND TRADING, L.P., a Utah limited partnership, or its successors or assigns (“Lender”), $5,700,000.00 and any interest, fees, charges, and late fees on the date that is twenty-four (24) months after the Purchase Price Date (the “Maturity Date”) in accordance with the terms set forth herein and to pay interest on the Outstanding Balance at the rate of ten percent (10%) per annum from the Purchase Price Date until the same is paid in full. This Secured Convertible Promissory Note (this “Note”) is issued and made effective as of January 30, 2019 (the “Effective Date”). This Note is issued pursuant to that certain Securities Purchase Agreement dated January 30, 2019, as the same may be amended from time to time, by and between Borrower and Lender (the “Purchase Agreement”). All interest calculations hereunder shall be computed on the basis of a 360-day year comprised of twelve (12) thirty (30) day months, shall compound daily and shall be payable in accordance with the terms of this Note. Certain capitalized terms used herein are defined in Attachment 1 attached hereto and incorporated herein by this reference.

This Note carries an OID of $600,000.00. In addition, Borrower agrees to pay $100,000.00 to Lender to cover Lender’s legal fees, accounting costs, due diligence, monitoring and other transaction costs incurred in connection with the purchase and sale of this Note (the “Transaction Expense Amount”), all of which amount is included in the initial principal balance of this Note. The purchase price for this Note shall be $5,000,000.00 (the “Purchase Price”), computed as follows: $5,700,000.00 original principal balance, less the OID, less the Transaction Expense Amount. The Purchase Price shall be payable by Lender to Borrower by wire transfer of immediately available funds.

1. Payment; Prepayment.

1.1. Payment. Provided there is an Outstanding Balance, on each Redemption Date (as defined below), Borrower shall pay to Lender an amount equal to the Redemption Amount (as defined below) due on such Redemption Date in accordance with Section 8. 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, so long as Borrower has not received a Lender Conversion Notice (as defined below) or a Redemption Notice (as defined below) from Lender where the applicable Conversion Shares have not yet been delivered and so long as no Event of Default (as defined below) has occurred and is continuing, then Borrower shall have the right, exercisable on not less than five (5) Trading Days prior written notice to Lender to prepay the Outstanding Balance of this Note, in part or in full, in accordance with this Section 1. Any notice of prepayment hereunder (an “Optional Prepayment Notice”) shall be delivered to Lender at its registered address and shall state: (i) that Borrower is exercising its right to prepay this Note, and (ii) the date of prepayment, which shall be not less than five (5) Trading Days from the date of the Optional Prepayment Notice. On the date fixed for prepayment (the “Optional Prepayment Date”), Borrower shall make payment of the Optional Prepayment Amount (as defined below) to or upon the order of Lender as may be specified by Lender in writing to Borrower. If Borrower exercises its right to prepay this Note, Borrower shall make payment to Lender of an amount in cash equal to 115% multiplied by the then Outstanding Balance of this Note being prepaid (the “Optional Prepayment Amount”). In the event Borrower delivers the Optional Prepayment Amount to Lender prior to the Optional Prepayment Date or without delivering an Optional Prepayment Notice to Lender as set forth herein without Lender’s prior written consent, the Optional Prepayment Amount shall not be deemed to have been paid to Lender until the Optional Prepayment Date. In the event Borrower delivers the Optional Prepayment Amount without an Optional Prepayment Notice, then the Optional Prepayment Date will be deemed to be the date that is five (5) Trading Days from the date that the Optional Prepayment Amount was delivered to Lender and Lender shall be entitled to exercise its conversion rights set forth herein during such five (5) day period. In addition, if Borrower delivers an Optional Prepayment Notice and fails to pay the Optional Prepayment Amount due to Lender within two (2) Trading Days following the Optional Prepayment Date, Borrower shall forever forfeit its right to prepay this Note.

2. Security. This Note is secured by that certain Security Agreement of even date herewith, as the same may be amended from time to time (the “Security Agreement”), executed by Borrower in favor of Lender encumbering certain of Borrower’s assets, as more specifically set forth in the Security Agreement, all the terms and conditions of which are hereby incorporated into and made a part of this Note.

3. Lender Optional Conversion.

3.1. Lender Conversions. Lender has the right at any time after the date that is six (6) months from the Purchase Price Date until the Outstanding Balance has been paid in full, including without limitation until any Optional Prepayment Date (even if Lender has received an Optional Prepayment Notice) or at any time thereafter with respect to any amount that is not prepaid, at its election, to convert (each instance of conversion is referred to herein as a “Lender Conversion”) all or any part of the Outstanding Balance into shares (“Lender Conversion Shares”) of fully paid and non-assessable common stock, $0.001 par value per share (“Common Stock”), of Borrower as per the following conversion formula: the number of Lender Conversion Shares equals the amount being converted (the “Conversion Amount”) divided by the Lender Conversion Price (as defined below). Conversion notices in the form attached hereto as Exhibit A (each, a “Lender Conversion Notice”) may be effectively delivered to Borrower by facsimile, email, mail, overnight courier, or personal delivery, and all Lender Conversions shall be cashless and not require further payment from Lender. Borrower shall deliver the Lender Conversion Shares from any Lender Conversion to Lender in accordance with Section 9 below.

2

3.2. Lender Conversion Price. Subject to adjustment as set forth in this Note, the price at which Lender has the right to convert all or any portion of the Outstanding Balance into Common Stock is $0.50 per share of Common Stock (the “Lender Conversion Price”).

4. Defaults and Remedies.

4.1. Defaults. The following are events of default under this Note (each, an “Event of Default”): (a) Borrower fails to pay any principal, interest, fees, charges, or any other amount when due and payable hereunder; (b) Borrower fails to deliver any Conversion Shares in accordance with the terms hereof; (c) a receiver, trustee or other similar official shall be appointed over Borrower or a material part of its assets and such appointment shall remain uncontested for twenty (20) days or shall not be dismissed or discharged within sixty (60) days; (d) Borrower generally fails to pay, or admits in writing its inability to pay, its debts as they become due, subject to applicable grace periods, if any; (e) Borrower makes a general assignment for the benefit of creditors; (f) Borrower files a petition for relief under any bankruptcy, insolvency or similar law (domestic or foreign); (g) an involuntary bankruptcy proceeding is commenced or filed against Borrower; (h) Borrower or any pledgor, trustor, or guarantor of this Note defaults or otherwise fails to observe or perform any covenant, obligation, condition or agreement of Borrower or such pledgor, trustor, or guarantor contained herein or in any other Transaction Document (as defined in the Purchase Agreement), other than those specifically set forth in this Section 4.1 and Section 4 of the Purchase Agreement and other than the covenant with respect to Unapproved Debt Issuances; (i) any representation, warranty or other statement made or furnished by or on behalf of Borrower or any pledgor, trustor, or guarantor of this Note to Lender herein, in any Transaction Document, or otherwise in connection with the issuance of this Note is false, incorrect, incomplete or misleading in any material respect when made or furnished; (j) the closing of a Fundamental Transaction without Lender’s prior written consent; provided, that such consent shall not be required in connection with the closing of a Fundamental Transaction where the Note is repaid in full at or prior to the closing of such Fundamental Transaction; (k) Borrower fails in any material respect to maintain the Share Reserve as required under the Purchase Agreement; (l) Borrower effectuates a reverse split of its Common Stock without ten (10) Trading Days prior written notice to Lender; (m) any money judgment, writ or similar process is entered or filed against Borrower or any subsidiary of Borrower or any of its property or other assets for more than $500,000.00, and shall remain unvacated, unbonded or unstayed for a period of twenty (20) calendar days unless otherwise consented to by Lender; (n) Borrower fails, in any material respect, to observe or perform any covenant set forth in Section 4 of the Purchase Agreement (other than the covenant with respect to Unapproved Debt Issuances); (o) Borrower shall make any Unapproved Debt Issuance; or (p) Borrower, any affiliate of Borrower, or any pledgor, trustor, or guarantor of this Note breaches, in any material respect, any covenant or other term or condition contained in any Other Agreements. Notwithstanding the foregoing, the occurrence of any event specified in Section 4.1(i) – (q) shall not be considered an Event of Default hereunder is such event is cured within forty-five (45) days of the occurrence of such event.

4.2. Remedies. At any time and from time to time after Lender becomes aware of the occurrence of any Event of Default that is continuing, 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, at any time following the occurrence of any Event of Default, Lender may, at its option, elect to increase the Outstanding Balance by applying the Default Effect (subject to the limitation set forth below) via written notice to Borrower without accelerating the Outstanding Balance, in which event the Outstanding Balance shall be increased as of the date of the occurrence of the applicable Event of Default pursuant to the Default Effect, but the Outstanding Balance shall not be immediately due and payable unless so declared by Lender (for the avoidance of doubt, if Lender elects to apply the Default Effect pursuant to this sentence, it shall reserve the right to declare the Outstanding Balance immediately due and payable at any time and no such

3

election by Lender shall be deemed to be a waiver of its right to declare the Outstanding Balance immediately due and payable as set forth herein unless otherwise agreed to by Lender in writing). Notwithstanding the foregoing, upon the occurrence of any Event of Default described in clauses (c), (d), (e), (f), or (g) of Section 4.1, the Outstanding Balance as of the date of acceleration shall become immediately and automatically due and payable in cash at the Mandatory Default Amount, without any written notice required by Lender. 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 22% per annum or the maximum rate permitted under applicable law (“Default Interest”). For the avoidance of doubt, Lender may continue making Lender Conversions and Redemption Conversions (as defined below) at any time following an Event of Default until such time as the Outstanding Balance is paid in full. Borrower further acknowledges and agrees that Lender may continue making Conversions following the entry of any judgment or arbitration award in favor of Lender until such time that the entire judgment amount or arbitration award is paid in full. Borrower agrees that any judgment or arbitration award will, by its terms, be made convertible into Common Stock. Borrower and Lender agree and stipulate that any judgment or arbitration award entered against Borrower shall be reduced by $1,000.00 and such $1,000.00 shall become the new Outstanding Balance of this Note and this Note shall expressly survive such judgment or arbitration award. Additionally, following the occurrence of any Event of Default, Borrower may, at its option, pay any Lender Conversion in cash instead of Lender Conversion Shares by paying to Lender on or before the applicable Delivery Date (as defined below) a cash amount equal to the number of Lender Conversion Shares set forth in the applicable Lender Conversion Notice multiplied by the highest intra-day trading price of the Common Stock that occurs during the period beginning on the date the applicable Event of Default occurred and ending on the date of the applicable Lender Conversion Notice. 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 Event of Default or impair any right consequent thereon. Nothing herein shall limit Lender’s right to pursue in one or more arbitrations 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.

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. Rights Upon Issuance of Securities.

7.1. Subsequent Equity Sales. Except with respect to Excluded Securities, if Borrower or any subsidiary thereof, as applicable, at any time this Note is outstanding, shall sell, issue or grant any Common Stock, option to purchase Common Stock, right to reprice, preferred shares convertible into Common Stock, or debt, warrants, options or other instruments or securities to Lender or any third party which are convertible into or exercisable or exchangeable for shares of Common Stock (collectively, the “Equity Securities”) in any offering where Borrower sells securities that have been registered under the Securities Act, at an effective price per share less than the then effective Lender Conversion Price (such issuance is referred to herein as a “Dilutive Issuance”), then, the Lender Conversion Price shall be automatically reduced and only reduced to equal such lower effective price per share. If the holder of any Equity Securities so issued shall at any time, whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or otherwise, or due to warrants, options, or rights per share which are issued in connection with such Dilutive Issuance, be entitled to receive shares of Common Stock at an effective price per share that is less than the Lender Conversion Price, such issuance shall be deemed to have occurred for less than the Lender Conversion Price on the date of such Dilutive Issuance, and the then effective Lender Conversion Price shall be reduced and only reduced to equal such lower effective price per share. Such adjustments described above to the Lender Conversion Price shall be permanent (subject to additional adjustments under this section), and shall be made whenever such Equity Securities are issued. Borrower shall notify Lender, in writing, no later than the Trading Day following the issuance of any Equity Securities subject to this Section 7.1, indicating therein the applicable issuance price, or applicable reset price, exchange price, conversion price, or other pricing terms (such notice, the “Dilutive Issuance Notice”). For purposes of clarity, whether or not Borrower provides a Dilutive Issuance Notice pursuant to this Section 7.1, upon the occurrence of any Dilutive Issuance, on the date of such Dilutive Issuance the Lender Conversion Price shall be lowered to equal the applicable effective price per share regardless of whether Borrower or Lender accurately refers to such lower effective price per share in any subsequent Redemption Notice or Lender Conversion Notice.

7.2. Adjustment of Lender Conversion Price upon Subdivision or Combination of Common Stock. Without limiting any provision hereof, if Borrower at any time on or after the Effective Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Lender Conversion Price in effect immediately prior to such subdivision will be proportionately reduced. Without limiting any provision hereof, if Borrower at any time on or after the Effective Date combines (by combination, reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Lender Conversion Price in effect immediately prior to such combination will be proportionately increased. Any adjustment pursuant to this Section 7.2 shall become effective immediately after the effective date of such subdivision or combination. If any event requiring an adjustment under this Section 7.2 occurs during the period that a Lender Conversion Price is calculated hereunder, then the calculation of such Lender Conversion Price shall be adjusted appropriately to reflect such event.

8. Borrower Redemptions.

8.1. Redemption Conversion Price. Subject to the adjustments set forth herein, the conversion price for each Redemption Conversion (as defined below) (the “Redemption Conversion Price”) shall be the lesser of (a) the Lender Conversion Price, and (b) the Market Price.

5

8.2. Redemption Conversions. Beginning on the date that is six (6) months 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”) up to the Maximum Monthly Redemption Amount by providing Borrower with a notice substantially in the form attached hereto as Exhibit B (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 so long as the aggregate Redemption Amounts for each calendar month do not exceed the Maximum Monthly Redemption Amount. Payments of each Redemption Amount may be made (a) in cash, or (b) by converting such Redemption Amount into shares of Common Stock (“Redemption Conversion Shares”, and together with the Lender Conversion Shares, the “Conversion Shares”) in accordance with this Section 8.2 (each, a “Redemption Conversion”) per the following formula: the number of Redemption Conversion Shares equals the portion of the applicable Redemption Amount being converted divided by the Redemption Conversion Price, or (c) by any combination of the foregoing, so long as the cash is delivered to Lender on the fifth (5^th) 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 that failure to repay this Note in full by the Maturity Date is an Event of Default, the Redemption Dates shall continue after the Maturity Date pursuant to this Section 8.2 until the Outstanding Balance is repaid in full, provided that the aggregate Redemption Amounts in any given calendar month following an Event of Default may exceed the Maximum Monthly Redemption.

8.3. 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 twenty-four (24) hours 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 9 below on or before each applicable Delivery Date. If Borrower elects to pay a Redemption Amount in cash, such payment must be delivered on the second Trading Day immediately following the Redemption Date. If Borrowers elects to make a payment in cash and fails to make such payment by the required due date on two (2) separate occasions, Borrower shall lose the right to make payments of Redemption Amounts in cash in the future without Lender’s written consent.

9. Method of Conversion Share Delivery. On or before the close of business on the fifth (5^th) Trading Day following each Redemption Date or the fifth (5^th) Trading Day following the date of delivery of a Lender Conversion Notice, as applicable (the “Delivery Date”), Borrower shall, provided it is DWAC Eligible at such time, deliver or cause its transfer agent to deliver the applicable Conversion Shares electronically via DWAC to the account designated by Lender in the applicable Lender Conversion Notice or Redemption Notice. If Borrower is not DWAC Eligible, it shall deliver to Lender or its broker (as designated in the Lender Conversion Notice or Redemption Notice, as applicable), via reputable overnight courier, a certificate representing the number of shares of Common Stock 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

6

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 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 9. In conjunction therewith, Borrower will also deliver to Lender a written explanation from its counsel or its transfer agent’s counsel explaining why the issuance of the applicable Conversion Shares violates Rule 144.

10. Conversion Delays. If Borrower fails to deliver Conversion Shares in accordance with the timeframes stated in Section 9, Lender, at any time prior to selling all of those Conversion Shares, may rescind in whole or in part that particular Conversion attributable to the unsold Conversion Shares, 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 sixth (6^th) Trading Day (inclusive of the day of the Lender Conversion), a late fee equal to 1.5% of the applicable Lender Conversion Share Value rounded to the nearest multiple of $100.00 (but in any event the cumulative amount of such late fees for each Lender Conversion shall not exceed 200% of the applicable Lender Conversion Share Value) will be assessed for each day beginning on the sixth (6^th) Trading Day (inclusive of the day of the Lender Conversion) until Lender Conversion Share delivery is made; and such late fee will be added to the Outstanding Balance (such fees, the “Conversion Delay Late Fees”).

11. Approved Debt Issuance. The Outstanding Balance will automatically be increased by five percent (5%) for each Approved Debt Issuance made by Borrower (without the need for Lender to provide any notice to Borrower of such increase), which increase will be effective as of the date of each applicable Approved Debt Issuance.

12. Ownership Limitation. Notwithstanding anything to the contrary contained in this Note or the other Transaction Documents, if at any time Lender shall or would be issued shares of Common Stock under any of the Transaction Documents, but such issuance would cause Lender (together with its affiliates) to beneficially own a number of shares exceeding 4.99% of the number of shares of Common Stock outstanding on such date (including for such purpose the shares of Common Stock issuable upon such issuance) (the “Maximum Percentage”), then Borrower shall not issue to Lender shares of Common Stock which would exceed the Maximum Percentage. Lender agrees, upon request, to provide Borrower with the number of shares of Common Stock it owns at the time of any proposed Conversion hereunder. For purposes of this section, beneficial ownership of Common Stock will be determined pursuant to Section 13(d) of the 1934 Act. The shares of Common Stock issuable to Lender that would cause the Maximum Percentage to be exceeded are referred to herein as the “Ownership Limitation Shares”. Borrower will reserve the Ownership Limitation Shares for the exclusive benefit of Lender. Lender shall notify Borrower in writing of the number of the Ownership Limitation Shares that may be issued to Lender without causing Lender to exceed the Maximum Percentage. Upon receipt of such notice, Borrower shall be unconditionally obligated to immediately issue such designated shares to Lender, with a corresponding reduction in the number of the Ownership Limitation Shares. Upon notice to Borrower from Lender the term “4.99%” above shall be replaced with “9.99%”. 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.

7

13. Payment of Collection Costs. If this Note is placed in the hands of an attorney for collection or enforcement prior to commencing arbitration or legal proceedings, or is collected or enforced through any arbitration or legal proceeding, or Lender otherwise takes action to collect amounts due under this Note or to enforce the provisions of this Note, then Borrower shall pay the costs incurred by Lender for such collection, enforcement or action including, without limitation, attorneys’ fees and disbursements. Borrower also agrees to pay for any costs, fees or charges of its transfer agent that are charged to Lender pursuant to any Conversion or issuance of shares pursuant to this Note.

14. Opinion of Counsel. In the event that an opinion of counsel is needed for any matter related to this Note, Lender has the right to have any such opinion provided by its counsel; provided that such opinion shall be reasonably acceptable to Borrower.

15. 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.

16. Resolution of Disputes.

16.1. Arbitration of Disputes. By its 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.

16.2. Calculation Disputes. Notwithstanding the Arbitration Provisions, in the case of a dispute as to any Calculation (as defined in the Purchase Agreement), such dispute will be resolved in the manner set forth in the Purchase Agreement.

17. 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.

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

19. Assignments. Borrower may not assign this Note without the prior written consent of Lender. This Note and any shares of Common Stock issued upon conversion of this Note may be offered, sold, assigned or transferred by Lender without the consent of Borrower.

20. Time is of the Essence. Time is expressly made of the essence with respect to each and every provision of this Note and the documents and instruments entered into in connection herewith.

21. 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.”

22. 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

8

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, if allowed under applicable law, tack back to the Purchase Price Date for purposes of determining the holding period under Rule 144).

23. Waiver of Jury Trial. EACH OF LENDER AND BORROWER IRREVOCABLY WAIVES ANY AND ALL RIGHTS SUCH PARTY MAY HAVE TO DEMAND THAT ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR IN ANY WAY RELATED TO THIS NOTE OR THE RELATIONSHIPS OF THE PARTIES HERETO BE TRIED BY JURY. THIS WAIVER EXTENDS TO ANY AND ALL RIGHTS TO DEMAND A TRIAL BY JURY ARISING UNDER COMMON LAW OR ANY APPLICABLE STATUTE, LAW, RULE OR REGULATION. FURTHER, EACH PARTY HERETO ACKNOWLEDGES THAT SUCH PARTY IS KNOWINGLY AND VOLUNTARILY WAIVING SUCH PARTY’S RIGHT TO DEMAND TRIAL BY JURY.

24. Voluntary Agreement. Borrower has carefully read this Note and has asked any questions needed for Borrower to understand the terms, consequences and binding effect of this Note and fully understand them. Borrower has had the opportunity to seek the advice of an attorney of Borrower’s choosing, or has waived the right to do so, and is executing this Note voluntarily and without any duress or undue influence by Lender or anyone else.

25. 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.

DEFINITIONS

For purposes of this Note, the following terms shall have the following meanings:

A1. “Approved Debt Issuance” means a Debt Issuance (as defined in the Purchase Agreement) for which Borrower received Lender’s written consent prior to the applicable issuance.

A2. “Approved Stock Plan” means any equity compensation plan which has been approved by the shareholders of Borrower and is in effect as of the Purchase Price Date, pursuant to which Borrower’s securities may be issued to any employee, officer or director for services provided to Borrower.

A3. “Bloomberg” means Bloomberg L.P. (or if that service is not then reporting the relevant information regarding the Common Stock, a comparable reporting service of national reputation selected by Lender and reasonably satisfactory to Borrower).

A4. “Closing Bid Price” and “Closing Trade Price” means the last closing bid price and last closing trade price, respectively, for the Common Stock on its principal market, as reported by Bloomberg, or, if its principal market begins to operate on an extended hours basis and does not designate the closing bid price or the closing trade price (as the case may be) then the last bid price or last trade price, respectively, of the Common Stock prior to 4:00:00 p.m., New York time, as reported by Bloomberg, or, if its principal market is not the principal securities exchange or trading market for the Common Stock, the last closing bid price or last trade price, respectively, of the Common Stock on the principal securities exchange or trading market where the Common Stock is listed or traded as reported by Bloomberg, or if the foregoing do not apply, the last closing bid price or last trade price, respectively, of the Common Stock in the over-the-counter market on the electronic bulletin board for the Common Stock as reported by Bloomberg, or, if no closing bid price or last trade price, respectively, is reported for the Common Stock by Bloomberg, the average of the bid prices, or the ask prices, respectively, of any market makers for the Common Stock as reported by OTC Markets Group, Inc., and any successor thereto.
