(“Sales Commencement Date”)

Know Labs, Inc., a Nevada corporation (the “Company”) hereby certifies Sutter Securities Group, Inc. (“Holder”), as the registered owner of this Unit Purchase Option (“Unit Purchase Option” or “UPO”), and that Holder is entitled, at any time or from time to time commencing on the date that is 180 days after the Sales Commencement Date, which shall be the effective date (the “Effective Date”) of the Company’s registration statement on Form S-1 (File No.: 333-280273) (the “Registration Statement”) pursuant to which units (each unit consisting of one share of the Company’s Common Stock, par value $0.001 per share (“Share”), and one Warrant of the Company) are offered for sale to the public (the “Offering”) by and at or before 5:00 p.m., Eastern Time, on the fifth anniversary of the Sales Commencement Date (the “Expiration Date”), but not thereafter, to subscribe for, purchase and receive, in whole or in part, up to 463,750 units (the “Units”), each Unit consisting of one Share and one Warrant of the Company. The Warrant included in each Unit will be identical to the Warrants included in the Units offered to the public by the Company pursuant to the Registration Statement. If the Expiration Date is a day on which banking institutions are authorized by law to close, then this UPO may be exercised on the next succeeding day which is not such a day in accordance with the terms herein. During the period ending on the Expiration Date, the Company agrees not to take any action that would terminate the UPO. This UPO is initially exercisable at $0.26 per Unit (or 100% of the public offering price of the Units being sold in the Offering) so purchased; provided, however, that upon the occurrence of any of the events specified in Section 5 hereof, the rights granted by this UPO, including the exercise price per Unit and the number of Units to be received upon such exercise, shall be adjusted as therein specified. This UPO is one of the UPOs issued pursuant to (i) Section 1.3 of the Underwriting Agreement, dated as of August 7, 2024, by and among the Company and Boustead Securities, LLC and The Benchmark Company, LLC, as the Representatives of the several underwriters, if any, named in Schedule I thereto (the “Underwriting Agreement”) and (ii) the Company’s Registration Statement.

1. EXERCISE OF UPO.

(a) Mechanics of Exercise. Subject to the terms and conditions hereof, this UPO may be exercised by the Holder on any day on or after the date that is 180 days after the Effective Date (the “Exercisability Date”), on one or more occasions, in whole or in part (but not as to fractional shares), by delivery of a written notice, in the form attached hereto as Exhibit A (the “Exercise Notice”) of the Holder’s election to exercise this UPO. No ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise form be required. Within two (2) Trading Days of the delivery of such Exercise Notice, if the Holder is not electing a Cashless Exercise (as defined below) pursuant to Section 1(d) of this UPO, the Holder shall pay to the Company an amount equal to the applicable Exercise Price multiplied by the number of Units as to which this UPO is being exercised (the “Aggregate Exercise Price”) in cash or wire transfer of immediately available funds (a “Cash Exercise”). The Holder shall not be required to surrender this UPO in order to effect an exercise hereunder; provided, however, that in the event that this UPO is exercised in full or for the remaining unexercised portion hereof, the Holder shall deliver this UPO to the Company for cancellation within a reasonable time after such exercise. On or before the first Trading Day following the date on which the Company has received the Exercise Notice (the date upon which the Company has received the Exercise Notice, the “Exercise Date”), the Company shall transmit by facsimile or email transmission an acknowledgment of confirmation of receipt of the Exercise Notice to the Holder and the Company’s transfer agent for the Common Stock (the “Transfer Agent”). The Company shall deliver any objection to the Exercise Notice on or before the second Trading Day following the date on which the Company has received the Exercise Notice. On or before the second Trading Day following the date on which the Company has received the Exercise Notice, provided the Aggregate Exercise Price has been received by the Company prior to such Trading Day, the Company shall, (X) provided that the Transfer Agent is participating in The Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program (the “FAST Program”) and so long as the certificates therefor are not required to bear a legend regarding restriction on transferability, upon the request of the Holder, credit such aggregate number of shares of Common Stock and Warrants included in the Units to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s balance account with DTC through its Deposit Withdrawal Agent Commission system, or (Y), if the Transfer Agent is not participating in the FAST Program or if the certificates are required to bear a legend regarding restriction on transferability, issue and dispatch by overnight courier to the address as specified in the Exercise Notice, a certificate, registered in the Company’s share register in the name of the Holder or its designee, for the number of Shares and Warrants to which the Holder is entitled pursuant to such exercise. Upon delivery of the Exercise Notice and payment of the Aggregate Exercise Price, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Shares and Warrants with respect to which this UPO has been exercised, irrespective of the date such Shares and Warrants are credited to the Holder’s DTC account or the date of delivery of the certificates evidencing such Shares and Warrants, as the case may be. If this UPO is submitted in connection with any exercise pursuant to this Section 1(a) and the number of Units represented by this UPO submitted for exercise is greater than the number of Units being acquired upon an exercise, then the Company shall as soon as practicable and in no event later than three Trading Days after any such submission and at its own expense, issue a new UPO (in accordance with Section 7(d)) representing the right to purchase the number of Units purchasable immediately prior to such exercise under this UPO, less the number of Units with respect to which this UPO has been and/or is exercised. The Company shall pay any and all taxes and other expenses of the Company (including overnight delivery charges) that may be payable with respect to the issuance and delivery of Units upon exercise of this UPO; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the registration of any certificates for Shares, Warrants or UPOs in a name other than that of the Holder or an affiliate thereof. The Holder shall be responsible for all other tax liability that may arise as a result of holding or transferring this UPO or receiving Units upon exercise hereof.

(b) Exercise Price. For purposes of this UPO, “Exercise Price” means $0.26 subject to adjustment as provided herein.

(c) Company’s Failure to Timely Deliver Securities. If the Company shall fail for any reason or for no reason to issue to the Holder within five (5) Business Days of the Exercise Date certificates for the number of Shares and Warrants included in the Units to which the Holder is entitled and register such Shares and Warrants on the Company’s share and warrant register, or to credit the Holder’s balance account with DTC for such number of Shares and Warrants included in the Units to which the Holder is entitled upon the Holder’s exercise of this UPO, and if on or after such Trading Day the Holder purchases, or another Person purchasers on the Holder’s behalf or for the Holder’s account (in an open market transaction or otherwise) Shares and Warrants to deliver in satisfaction of a sale by the Holder of Shares and Warrants issuable upon such exercise that the Holder anticipated receiving from the Company, then the Company shall, within three (3) Business Days after the Holder’s written request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions, if any) for the Shares and Warrants so purchased (the “Buy-In Price”), at which point the Company’s obligation to deliver such certificates (and to issue such Shares and Warrants) shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such Shares and Warrants and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of Shares and Warrants, respectively, times (B) the Weighted Average Price (as reported by Bloomberg) of the Shares and Warrants, respectively, on the date of the event giving rise to the Company’s obligation to deliver such certificates.

(d) Cashless Exercise. In lieu of the payment of the Exercise Price multiplied by the number of Units for which this UPO is exercisable (and in lieu of being entitled to receive Units) in the manner required by Section 1(a), the Holder shall have the right (but not the obligation) to convert any exercisable but unexercised portion of this UPO into Units (the “Conversion Right”) as follows:

A. Upon exercise of the Conversion Right, the Company shall deliver to the Holder (without payment by the Holder of any of the Exercise Price in cash) that number of Units equal to the quotient obtained by dividing (x) the Value of the portion of the UPO being converted by (y) the combined Current Market Price of a Share and a Warrant.

B. The “Value” of the portion of the UPO being converted shall equal the remainder derived by subtracting (a) (i) the Exercise Price multiplied by (ii) the number of Units underlying the portion of this UPO being converted, from (b) the combined Current Market Value of a Share and a Warrant multiplied by the number of Units underlying the portion of the UPO being converted.

C. As used herein, the term “Current Market Value” per Unit at any date means the remainder derived by subtracting (x) the exercise price per Unit from (y) the combined Current Market Price of a Share and a Warrant.

D. The “Current Market Price” of a Share or a Warrant shall mean (i) if the Shares or Warrants are listed on a national securities exchange or quoted on the OTCQB or OTCQX (or any successor exchange or entity), the closing or last sale price of the Shares or Warrants (as applicable) in the principal trading market for the Shares or the Warrants on the last trading day preceding the day in question as reported by the exchange, the OTCQB or OTCQX, as the case may be; (ii) if the Shares or Warrants are not listed on a national securities exchange or quoted on the OTCQB or OTCQX, but are traded in the residual over-the-counter market, the closing bid price for the Shares or Warrants (as applicable) on the last trading day preceding the date in question for which such quotations are reported in the “Pink Sheets” published by OTC Markets Group, Inc. or similar publisher of such quotations; and (iii) if the fair market value of the Shares or Warrants cannot be determined pursuant to clause (i) or (ii) above, such price as the Board of Directors of the Company shall determine, in good faith.

E. The Conversion Right may be exercised by the Holder on any business day on or after the Exercisability Date and not later than the Expiration Date by delivering the UPO with the duly executed exercise form attached hereto with the cashless exercise section completed to the Company, exercising the Conversion Right and specifying the total number of Units the Holder will purchase pursuant to such Conversion Right.

(e) Rule 144. For purposes of Rule 144(d) promulgated under the Securities Act of 1933, as amended, as in effect on the date hereof, assuming the Holder is not an affiliate of the Company, it is intended that the Units issued in a Cashless Exercise shall be deemed to have been acquired by the Holder, and the holding period for the Units shall be deemed to have commenced, on the Issuance Date.

(f) Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Units, the Company shall promptly issue to the Holder the number of Units that are not disputed.

(g) Beneficial Ownership. The Company shall not effect the exercise of this UPO, and the Holder shall not have the right to exercise this UPO, to the extent that after giving effect to such exercise, such Person (together with such Person’s affiliates) would beneficially own in excess of 4.99% (the “Maximum Percentage”) of the shares of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by such Person and its affiliates shall include the number of shares of Common Stock and Warrants issuable upon exercise of this UPO with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock and Warrants which would be issuable upon (i) exercise of the remaining, unexercised portion of this UPO beneficially owned by such Person and its affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by such Person and its affiliates (including, without limitation, any convertible notes or convertible preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). For purposes of this UPO, in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as reflected in the most recent of (1) the Company’s most recent Form 10-K, Form 10-Q, Current Report on Form 8-K or other public filing with the Securities and Exchange Commission, as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written or oral request of the Holder, the Company shall within two (2) Business Days confirm to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this UPO, by the Holder and its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. By written notice to the Company, the Holder may from time to time increase or decrease the Maximum Percentage to any other percentage not in excess of 9.99% specified in such notice; provided that (i) any such increase will not be effective until the sixty-first (61st) day after such notice is delivered to the Company, and (ii) any such increase or decrease will apply only to the Holder. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 1(g) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended beneficial ownership limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation.

2. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES. The Exercise Price and the number of Units shall be adjusted from time to time as follows:

(a) Voluntary Adjustment by Company. The Company may at any time during the term of this UPO reduce the then current Exercise Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Company.

(b) Adjustment upon Subdivision or Combination of Common Stock. If the Company at any time on or after the Issuance Date subdivides (by any stock split, stock dividend, recapitalization, reorganization, scheme, arrangement or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Exercise Price in effect immediately prior to such subdivision will be proportionately reduced and the number of Units will be proportionately increased. If the Company at any time on or after the Issuance Date combines (by any stock split, stock dividend, recapitalization, reorganization, scheme, arrangement or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately prior to such combination will be proportionately increased and the number of Units will be proportionately decreased. Any adjustment under this Section 2(b) shall become effective at the close of business on the date the subdivision or combination becomes effective.

(c) Other Events. If any event occurs of the type contemplated by the provisions of this Section 2 but not expressly provided for by such provisions (including, without limitation, the granting of stock appreciation rights or phantom stock rights), then the Company’s Board of Directors will make an appropriate adjustment in the Exercise Price and the number of Units so as to protect the rights of the Holder; provided that no such adjustment pursuant to this Section 2(c) will increase the Exercise Price or decrease the number of Units as otherwise determined pursuant to this Section 2.

3. RIGHTS UPON DISTRIBUTION OF ASSETS. If the Company, at any time while this UPO is outstanding, shall distribute to all holders of Common Stock (and not to the Holders) evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants to subscribe for or purchase any security other than the Common Stock (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction), then in each such case the Exercise Price shall be adjusted by multiplying the Exercise Price in effect immediately prior to the record date fixed for determination of stockholders entitled to receive such distribution by a fraction of which the denominator shall be the Weighted Average Price determined as of the record date mentioned above, and of which the numerator shall be such Weighted Average Price on such record date less the then per share fair market value at such record date of the portion of such assets or evidence of indebtedness so distributed applicable to one outstanding share of Common Stock as determined by the Board of Directors in good faith. In either case the adjustments shall be described in a statement provided to the Holder of the portion of assets or evidences of indebtedness so distributed or such subscription rights applicable to one share of Common Stock. Such adjustment shall be made whenever any such distribution is made and shall become effective immediately after the record date mentioned above.

4. PURCHASE RIGHTS; FUNDAMENTAL TRANSACTIONS.

(a) Purchase Rights. In addition to any adjustments pursuant to Section 2 above, if at any time the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this UPO (without regard to any limitations on the exercise of this UPO) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights.

(b) Fundamental Transactions. The Company shall not enter into or be party to a Fundamental Transaction unless the Successor Entity assumes in writing (unless the Company is the Successor Entity) all of the obligations of the Company under this UPO in accordance with the provisions of this Section (4)(b) pursuant to written agreements in form and substance reasonably satisfactory to the Required Holders and approved by the Required Holders prior to such Fundamental Transaction, including agreements to deliver to each holder of the UPOs in exchange for such UPOs securities of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this UPO, including, without limitation, an adjusted exercise price equal to the value for the Units reflected by the terms of such Fundamental Transaction, and exercisable for a corresponding number of units of securities equivalent to the shares of Common Stock and Warrants acquirable and receivable upon exercise of this UPO (without regard to any limitations on the exercise of this UPO) prior to such Fundamental Transaction, and reasonably satisfactory to the Required Holders. Upon the occurrence of any Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this UPO referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this UPO with the same effect as if such Successor Entity had been named as the Company herein. Upon consummation of the Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation that there shall be issued upon exercise of this UPO at any time after the consummation of the Fundamental Transaction, in lieu of the shares of Common Stock (or other securities, cash, assets or other property) issuable upon the exercise of the UPO prior to such Fundamental Transaction, such shares of the publicly traded common stock or common shares (or its equivalent) and warrants (or its equivalent) of the Successor Entity (including its Parent Entity) which the Holder would have been entitled to receive upon the happening of such Fundamental Transaction had this UPO been converted immediately prior to such Fundamental Transaction, as adjusted in accordance with the provisions of this UPO. In addition to and not in substitution for any other rights hereunder, prior to the consummation of any Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock (a “Corporate Event”), the Company shall make appropriate provision to insure that the Holder will thereafter have the right to receive upon an exercise of this UPO at any time after the consummation of the Corporate Event but prior to the Expiration Date, in lieu of shares of Common Stock and Warrants (or other securities, cash, assets or other property) purchasable upon the exercise of this UPO prior to such Corporate Event, such shares of stock, securities, cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights) which the Holder would have been entitled to receive upon the happening of such Corporate Event had this UPO been exercised immediately prior to such Corporate Event. Provision made pursuant to the preceding sentence shall be in a form and substance reasonably satisfactory to the Required Holders. The provisions of this Section 4(b) shall apply similarly and equally to successive Fundamental Transactions and Corporate Events and shall be applied without regard to any limitations on the exercise of this UPO.

(c) Applicability to Successive Transactions. The provisions of this Section shall apply similarly and equally to successive Fundamental Transactions and Corporate Events and shall be applied without regard to any limitations on the exercise of this UPO.

5. NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation, Bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this UPO, and will at all times in good faith comply with all the provisions of this UPO and take all actions consistent with effectuating the purposes of this UPO. Without limiting the generality of the foregoing, the Company (i) shall not increase the par value of any shares of Common Stock receivable upon the exercise of this UPO or the Warrant issuable upon exercise of the UPO above the Exercise Price then in effect, (ii) shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the exercise of this UPO, and (iii) shall, so long as this UPO is outstanding, take all action necessary to reserve and keep available out of its authorized and unissued shares of Common Stock, solely for the purpose of effecting the exercise of this UPO and the Warrants issuable upon exercise of the UPO, 100% of the number of shares of Common Stock and Warrants issuable upon exercise of this UPO then outstanding (without regard to any limitations on exercise).

6. UPO HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided herein, the Holder, solely in such Person’s capacity as a holder of this UPO, shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this UPO be construed to confer upon the Holder, solely in such Person’s capacity as the Holder of this UPO, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the Holder of the Shares which such Person is then entitled to receive upon the due exercise of this UPO. In addition, nothing contained in this UPO shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise of this UPO or otherwise) or as a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company.

7. REISSUANCE OF UPOS.

(a) Transfer of UPO. If this UPO is to be transferred, the Holder shall surrender this UPO to the Company and deliver the completed and executed Assignment Form, in the form attached hereto as Exhibit B, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new UPO (in accordance with Section 7(d)), registered as the Holder may request, representing the right to purchase the number of Units being transferred by the Holder and, if less than the total number of Units then underlying this UPO is being transferred, a new UPO (in accordance with Section 7(d)) to the Holder representing the right to purchase the number of Units not being transferred.

(b) Lost, Stolen or Mutilated UPO. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this UPO, and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to the Company in customary form and, in the case of mutilation, upon surrender and cancellation of this UPO, the Company shall execute and deliver to the Holder a new UPO (in accordance with Section 7(d)) representing the right to purchase the Units then underlying this UPO.

(c) Exchangeable for Multiple UPOs. This UPO is exchangeable, upon the surrender hereof by the Holder at the principal office of the Company, for a new UPO or UPOs (in accordance with Section 7(d)) representing in the aggregate the right to purchase the number of Units then underlying this UPO, and each such new UPO will represent the right to purchase such portion of such Units as is designated by the Holder at the time of such surrender; provided, however, that no UPOs for fractional shares of Common Stock and no fractional Warrants shall be given.

(d) Issuance of New UPOs. Whenever the Company is required to issue a new UPO pursuant to the terms of this UPO, such new UPO (i) shall be of like tenor with this UPO, (ii) shall represent, as indicated on the face of such new UPO, the right to purchase the Units then underlying this UPO (or in the case of a new UPO being issued pursuant to Section 7(a) or Section 7(c), the Units designated by the Holder which, when added to the number of Units underlying the other new UPOs issued in connection with such issuance, does not exceed the number of Units then underlying this UPO), (iii) shall have an issuance date, as indicated on the face of such new UPO which is the same as the Issuance Date, and (iv) shall have the same rights and conditions as this UPO.

8. NOTICES. The Company shall provide Holder with prompt written notice of all actions taken pursuant to this UPO. Whenever notice is required to be given under this UPO, unless otherwise provided herein, such notice shall be given in writing, will be mailed (a) if within the domestic United States by first-class registered or certified airmail, or nationally recognized overnight express courier, postage prepaid, or by email or (b) if delivered from outside the United States, by International Federal Express or email, and (c) will be deemed given (i) if delivered by first-class registered or certified mail domestic, three business days after so mailed, (ii) if delivered by nationally recognized overnight carrier, one business day after so mailed, (iii) if delivered by International Federal Express, two business days after so mailed and (iv) if delivered by email, upon electronic confirmation of receipt, and will be delivered and addressed as follows:

10. GOVERNING LAW; CONSENT TO JURISDICTION; WAIVER OF JURY TRIAL. This UPO shall be governed by, and construed in accordance with, the internal laws of the State of New York, without reference to the choice of law provisions thereof.

EACH OF THE COMPANY AND, BY ITS ACCEPTANCE HEREOF, THE HOLDER HEREBY WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS UPO AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER.

11. CONSTRUCTION; HEADINGS. This UPO shall be deemed to be jointly drafted by the Company and the Holder and shall not be construed against any person as the drafter hereof. The headings of this UPO are for convenience of reference and shall not form part of, or affect the interpretation of, this UPO.

12. DISPUTE RESOLUTION. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Shares, the Company shall submit the disputed determinations or arithmetic calculations via email within two (2) Business Days of receipt of the Exercise Notice giving rise to such dispute, as the case may be, to the Holder. If the Holder and the Company are unable to agree upon such determination or calculation of the Exercise Price or the Units within three Business Days of such disputed determination or arithmetic calculation being submitted to the Holder, then the Company shall, within two (2) Business Days submit via email (a) the disputed determination of the Exercise Price to an independent, reputable investment bank selected by the Company and approved by the Holder, which approval shall not be unreasonably withheld, or (b) the disputed arithmetic calculation of the Units to the Company’s independent, outside accountant. The Company shall cause the investment bank or the accountant, as the case may be, to perform the determinations or calculations and notify the Company and the Holder of the results no later than ten Business Days from the time it receives the disputed determinations or calculations. The prevailing party (which, for purposes of this UPO, is the party whose determinations or calculations is closest to those of the investment bank or the accountant, as the case may be) in any dispute resolved pursuant to this Section 12 shall be entitled to the full amount of all reasonable expenses, including all costs and fees paid or incurred in good faith, in relation to the resolution of such dispute.

The remedies provided in this UPO shall be cumulative and in addition to all other remedies available under this UPO, at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the right of the Holder to pursue actual damages for any failure by the Company to comply with the terms of this UPO.
