UNIT PURCHASE OPTION
FOR THE PURCHASE OF
UP TO 150,000 UNITS
(OR UP TO 172,500 IF THE OVER-ALLOTMENT
IS EXERCISED IN FULL) OF
AQUARON ACQUISITION CORP.

THIS CERTIFIES THAT, in consideration of $100.00 duly paid by or on behalf of Chardan Capital Markets, LLC (the “Holder”), as registered owner of this Unit Purchase Option (this “Purchase Option”), to Aquaron Acquisition Corp. (the “Company”), Holder is entitled, at any time or from time to time upon the consummation by the Company of a Business Combination (the “Commencement Date”), until, at or before 5:00 p.m., New York City local time, on the earlier of the five year anniversary of the effective date of the Registration Statement (as defined below) and the day immediately prior to the day on which the Company and all of its successors have been dissolved, but not thereafter (the “Expiration Date”), as described in the Company’s registration statement (the “Registration Statement”) pursuant to which Units (as defined below) are offered for sale to the public in the Company’s initial public offering (the “Offering”), to subscribe for, purchase and receive, in whole or in part, up to One Hundred and Fifty Thousand (150,000) units (“Units”) of the Company (or up to 172,500 if the over-allotment is exercised in full), each Unit consisting of one (1) share of one common stock, par value $0.0001 per share, of the Company (“Share(s)”), one (1) right to receive one-tenth (1/10) of a Share upon the consummation of a Business Combination (“Right(s)”), and one (1) redeemable warrant (“Warrant(s)”), each whole warrant entitling the holder thereof to purchase one (1) Share. Each Right has the same terms as the rights included in the units being registered for sale to the public by way of the Registration Statement (“Public Rights”). Each Warrant is the same as the whole warrant included in the Units being registered for sale to the public by way of the Registration Statement (the “Public Warrants”). The Warrants will not be exercisable or convertible more than five years from the commencement of sales of the Offering in compliance with FINRA Rule 5110(g)(8)(A). Notwithstanding anything to the contrary, the original Holder of this Purchase Option agrees that it will not be permitted to exercise this Purchase Option after the five-year anniversary of the commencement of sales of the Offering. During the period ending on the Expiration Date, the Company agrees not to take any action that would terminate this Purchase Option. This Purchase Option is initially exercisable at $11.50 per Unit so purchased; provided, however, that upon the occurrence of any of the events specified in Section 6 hereof, the rights granted by this Purchase Option, including the exercise price per Unit and the number of Units (and Shares, Warrants, and Rights) to be received upon such exercise, shall be adjusted as therein specified. The term “Exercise Price” shall mean the initial exercise price or the adjusted exercise price, depending on the context.

2.1 Exercise Form. In order to exercise this Purchase Option, the exercise form attached hereto must be duly executed and completed and delivered to the Company, together with this Purchase Option and payment of the Exercise Price for the Units being purchased payable in cash or by certified check or official bank check or pursuant to Section 2.3 hereof. If the subscription rights represented hereby shall not be exercised at or before 5:00 p.m., New York City local time, on the Expiration Date, this Purchase Option shall become and be void without further force or effect, and all rights represented hereby shall cease and expire.

2.2 Legend. Each certificate for the securities purchased under this Purchase Option shall bear a legend as follows, unless such securities have been registered under the Securities Act of 1933, as amended (“Act”):

“The securities represented by this certificate have not been registered under the Securities Act of 1933, as amended (“Act”) or the laws of applicable states or other jurisdictions. The securities may not be offered for sale, sold or otherwise transferred except pursuant to an effective registration statement under the Act, or pursuant to an exemption from registration under the Act and applicable laws of states or other jurisdictions.”

2.3 Cashless Exercise.

2.3.1 Determination of Amount. In lieu of the payment of the Exercise Price multiplied by the number of Units for which this Purchase Option is exercisable (and in lieu of being entitled to receive Shares, Rights and Warrants) in the manner required by Section 2.1, and subject to Section 6.1 hereof, the Holder shall have the right (but not the obligation) to convert any exercisable but unexercised portion of this Purchase Option into Units (“Cashless Exercise Right”) as follows: upon exercise of the Cashless Exercise 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 (or that number of Shares, Warrants, and Rights comprising that number of Units) equal to the number of Units to be exercised multiplied by the quotient obtained by dividing (x) the “Value” (as defined below) of the portion of this Purchase Option being converted by (y) the Current Market Value (as defined below). The “Value” of the portion of this Purchase Option being converted shall equal the remainder derived from subtracting (a) (i) the Exercise Price multiplied by (ii) the number of Units underlying the portion of this Purchase Option being converted from (b) the Current Market Value of a Unit multiplied by the number of Units underlying the portion of this Purchase Option being converted. As used herein, the term “Current Market Value” per Unit at any date means: (A) in the event that the Units, Shares, Public Warrants, and Public Rights are still trading, (i) if the Units are listed on a national securities exchange or quoted on the OTC Bulletin Board or successor exchange, the average reported last sale price of the Units in the principal trading market for the Units as reported by the exchange, Nasdaq or the Financial Industry Regulatory Authority (“FINRA”), as the case may be, for the three trading days preceding the date in question; or (ii) if the Units are not listed on a national securities exchange or quoted on the OTC Bulletin Board (or successor exchange), but are traded in the residual over-the-counter market, the average reported last sale price for Units for the three trading days preceding the date in question for which such quotations are reported by the Pink Sheets, LLC or similar publisher of such quotations; (B) in the event that the Units are not still trading but the Shares, Public Warrants, and Public Rights underlying the Units are still trading, the aggregate of (i) the product of (x) the Current Market Price (as defined below) of the Shares and (y) the number of the Shares underlying one Unit (which shall include the portion of a Share the holder of a Unit would automatically receive in connection with the Right included in each such Unit), plus (ii) the product of (x) the Current Market Price of the Public Warrants and (y) the number of Warrants included in one Unit; or (C) in the event that neither the Units nor the Public Warrants are still trading, the aggregate of (i) the product of (x) the Current Market Price of the Shares and (y) the number of the Shares underlying one Unit (which shall include the portion of a Share the holder of a Unit would automatically receive in connection with the Right included in each such Unit), plus (ii) the remainder derived from subtracting (x) the exercise price of the Warrants multiplied by the number of Shares issuable upon exercise of the Warrants underlying one Unit from (y) the product of (aa) the Current Market Price of the Shares multiplied by (bb) the number of Shares underlying the Warrants included in each such Unit.

As used herein, the term “Current Market Value” per Unit at any date means: (A) in the event that the Units, Shares, Public Rights and Public Warrants are still trading, (i) if the Units are listed on a national securities exchange, the average reported last sale price of the Units in the principal trading market for the Units as reported by the exchange, as the case may be, for the three trading days preceding the date in question; or (ii) if the Units are not listed on a national securities exchange, but is traded in the over-the-counter market, the average reported last sale price for Units for the three trading days preceding the date in question for which such quotations are reported by the OTC Markets Group Inc., or similar publisher of such quotations; (B) in the event that the Units are not still trading but the Shares, Public Rights, and Public Warrants underlying the Units are still trading, the aggregate of (i) the product of (x) the Current Market Price of the Share and (y) the number of the Shares underlying one Unit (which shall include the portion of a Share the holder of a Unit would automatically receive in connection with the Right included in each such Unit), plus (ii) the product of (x) the Current Market Price of the Public Warrants and (y) the number of Warrants included in one Unit; or (C) in the event that neither the Units nor the Public Warrants are still trading, the aggregate of (i) the product of (x) the Current Market Price of the Shares and (y) the number of the Shares underlying one Unit (which shall include the portion of a Share the holder of a Unit would automatically receive in connection with the Right included in each such Unit), plus (ii) the remainder derived from subtracting (x) the exercise price of the Warrants multiplied by the number of Shares issuable upon exercise of the Warrants underlying one Unit from (y) the product of (aa) the Current Market Price of the Shares multiplied by (bb) the number of Shares underlying the Warrants included in each such Unit. The “Current Market Price” shall mean (i) if the Shares (or Public Warrants or Public Rights, as the case may be) are listed on a national securities exchange, the average reported last sale price of the Shares (or Public Warrants or Public Rights) in the principal trading market for the Share (or Public Warrants or Public Rights) as reported by the exchange, as the case may be, for the three trading days preceding the date in question; (ii) if the Shares (or Public Warrants or Public Rights) are not listed on a national securities exchange, but are traded in the over-the-counter market, the average reported last sale price for the Share (or Public Warrants or Public Rights) for the three (3) trading days preceding the date in question for which such quotations are reported by the OTC Markets Group Inc., or similar publisher of such quotations; and (iii) if the fair market value of the Share 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. In the event the Public Warrants have expired and are no longer exercisable, no “Value” shall be attributed to the Warrants underlying this Purchase Option.

2.3.2 Mechanics of Cashless Exercise. The Cashless Exercise Right may be exercised by the Holder on any business day on or after the Commencement Date and not later than the Expiration Date by delivering this Purchase Option with the duly executed exercise form attached hereto with the cashless exercise section completed to the Company, exercising the Cashless Exercise Right and specifying the total number of Units the Holder will purchase pursuant to such Cashless Exercise Right.

2.4 No Obligation to Net Cash Settle. Notwithstanding anything to the contrary contained in this Purchase Option, in no event will the Company be required to net cash settle the exercise of this Purchase Option or Warrants underlying this Purchase Option. The holder of this Purchase Option and Warrants underlying this Purchase Option will not be entitled to exercise this Purchase Option or the Warrants underlying such Purchase Option unless it exercises such Purchase Option pursuant to the Cashless Exercise Right or a registration statement is effective, or an exemption from the registration requirements is available at such time and, if the holder is not able to exercise this Purchase Option or underlying Warrants, this Purchase Option and/or the underlying Warrants, as applicable, will expire worthless.

3.1 General Restrictions. The registered Holder of this Purchase Option, by its acceptance hereof, agrees that it will not sell, transfer, assign, pledge or hypothecate this Purchase Option (or the Shares, Rights, and Warrants underlying this Purchase Option), or cause this Purchase Option (or the Shares, Rights, and Warrants underlying this Purchase Option) to be the subject of any hedging, short sale, derivative, put, or call transaction that would result in the effective economic disposition of this Purchase Option by any person, for a period of 180 days (pursuant to Rule 5110(e)(1) of the Conduct Rules of FINRA following the commencement of sales of the Offering to anyone other than (i) Chardan or an underwriter or selected dealer in connection with the Offering, or (ii) a bona fide officer or partner of Chardan or of any such underwriter or selected dealer. On and after the 181st day following the following the commencement of sales of the Offering, transfers to others may be made subject to compliance with or exemptions from applicable securities laws. In order to make any permitted assignment, the Holder must deliver to the Company the assignment form attached hereto duly executed and completed, together with this Purchase Option and payment of all transfer taxes, if any, payable in connection therewith. The Company shall within 5 business days transfer this Purchase Option on the books of the Company and shall execute and deliver a new Purchase Option of like tenor to the appropriate assignee(s) expressly evidencing the right to purchase the aggregate number of Units purchasable hereunder or such portion of such number as shall be contemplated by any such assignment.

3.2 Restrictions Imposed by the Act. The securities evidenced by this Purchase Option shall not be transferred unless and until (i) the Company has received the opinion of counsel for the Holder that the securities may be transferred pursuant to an exemption from registration under the Act and applicable state securities laws, the availability of which is established to the reasonable satisfaction of the Company (the Company hereby agreeing that the opinion of Loeb & Loeb LLP shall be deemed satisfactory evidence of the availability of an exemption), or (ii) a registration statement or a post-effective amendment to the Registration Statement relating to such securities has been filed by the Company and declared effective by the Securities and Exchange Commission (the “Commission”) and compliance with applicable state securities law has been established.

4.1 Partial Exercise or Transfer. Subject to the restrictions in Section 3 hereof, this Purchase Option may be exercised or assigned in whole or in part. In the event of the exercise or assignment hereof in part only, upon surrender of this Purchase Option for cancellation, together with the duly executed exercise or assignment form and funds sufficient to pay any Exercise Price (except to the extent that the Holder elects to exercise this Purchase Option by means of a cashless exercise as provided in Section 2.3 above) and/or transfer tax, the Company shall cause to be delivered to the Holder without charge a new Purchase Option of like tenor to this Purchase Option in the name of the Holder evidencing the right of the Holder to purchase the number of Units purchasable hereunder as to which this Purchase Option has not been exercised or assigned

4.2 Lost Certificate. Upon receipt by the Company of evidence satisfactory to it of the loss, theft, destruction or mutilation of this Purchase Option and of reasonably satisfactory indemnification or the posting of a bond, the Company shall execute and deliver a new Purchase Option of like tenor and date. Any such new Purchase Option executed and delivered as a result of such loss, theft, mutilation or destruction shall constitute a substitute contractual obligation on the part of the Company.

5.1 Demand Registration.

5.1.1 Grant of Right. The Company, upon written demand (“Initial Demand Notice”) of the Holder(s) of at least 51% of this Purchase Option and/or the underlying Units and/or the underlying securities (“Majority Holders”), agrees to use its best efforts to register (the “Demand Registration”) under the Act on one (1) occasion, all or any portion of the (i) Purchase Option requested by the Majority Holders in the Initial Demand Notice and all of the securities underlying such Purchase Option, including the Units, Shares, Warrants, Rights, and the Shares underlying the Warrants and Rights and (ii) the units issued to the Holder prior to or concurrently with the Offering and all securities underlying such units (collectively, the “Registrable Securities”). On such occasion, the Company will use its best efforts to file a registration statement or a post-effective amendment to the Registration Statement covering the Registrable Securities as expeditiously as possible, and in any event within forty-five (45) days, after receipt of the Initial Demand Notice and use its best efforts to have such registration statement or post-effective amendment declared effective as soon as possible thereafter. The demand for registration may be made at any time during a period of five years from the commencement of sales in the Offering. The Initial Demand Notice shall specify the number of shares of Registrable Securities proposed to be sold and the intended method(s) of distribution thereof. The Company will notify all holders of this Purchase Option and/or Registrable Securities of the demand within ten days from the date of the receipt of any such Initial Demand Notice. Each holder of Registrable Securities who wishes to include all or a portion of such holder’s Registrable Securities in the Demand Registration (each such holder including shares of Registrable Securities in such registration, a “Demanding Holder”) shall so notify the Company within fifteen (15) days after the receipt by the holder of the notice from the Company. Upon any such request, the Demanding Holders shall be entitled to have their Registrable Securities included in the Demand Registration, subject to Section 5.1.4. The Company shall not be required to effect more than one (1) Demand Registration under this Section 5.1 in respect of all Registrable Securities.

5.1.2 Effective Registration. Notwithstanding Section 5.1.5, a registration will not count as a Demand Registration until the registration statement filed with the Commission, with respect to such Demand Registration, has been declared effective and the Company has complied with all of its obligations under this Purchase Option with respect thereto.

5.1.3 Underwritten Offering. If the Majority Holders so elect and such holders so advise the Company as part of the Initial Demand Notice, the offering of such Registrable Securities pursuant to such Demand Registration shall be in the form of an underwritten offering. In such event, the right of any holder to include its Registrable Securities in such registration shall be conditioned upon such holder’s participation in such underwriting and the inclusion of such holder’s Registrable Securities in the underwriting to the extent provided herein. All Demanding Holders proposing to distribute their securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Majority Holders.

5.1.4 Reduction of Offering. If the managing underwriter or underwriters for a Demand Registration that is to be an underwritten offering advises the Company and the Demanding Holders in writing that the dollar amount or number of shares of Registrable Securities which the Demanding Holders desire to sell, taken together with all other Shares or other securities which the Company desires to sell and the Shares, if any, as to which registration has been requested pursuant to written contractual piggy-back registration rights held by other stockholders of the Company who desire to sell, exceeds the maximum dollar amount or maximum number of shares that can be sold in such offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of shares, as applicable, the “Maximum Number of Shares”), then the Company shall include in such registration: (i) first, the Registrable Securities as to which Demand Registration has been requested by the Demanding Holders (pro rata in accordance with the number of shares that each such person has requested be included in such registration, regardless of the number of shares held by each such person (such proportion is referred to herein as “Pro Rata”)) that can be sold without exceeding the Maximum Number of Shares; (ii) second, to the extent that the Maximum Number of Shares has not been reached under the foregoing clause (i), the Shares or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number of Shares; (iii) third, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (i) and (ii), the Shares or other securities registrable pursuant to the terms of the Registration Rights Agreement between the Company and the initial investors in the Company and Chardan, dated as of [*], 2022 (the “Registration Rights Agreement” and such registrable securities, the “Investor Securities”) as to which “piggy-back” registration has been requested by the holders thereof, Pro Rata, that can be sold without exceeding the Maximum Number of Shares; and (iv) fourth, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (i), (ii), and (iii), the Shares or other securities for the account of other persons that the Company is obligated to register pursuant to written contractual arrangements with such persons and that can be sold without exceeding the Maximum Number of Shares.

5.1.5 Withdrawal. If a majority-in-interest of the Demanding Holders disapprove of the terms of any underwriting or are not entitled to include all of their Registrable Securities in any offering, such majority-in-interest of the Demanding Holders may elect to withdraw from such offering by giving written notice to the Company and the underwriter or underwriters of their request to withdraw prior to the effectiveness of the registration statement filed with the Commission with respect to such Demand Registration. If the majority-in-interest of the Demanding Holders withdraws from a proposed offering relating to a Demand Registration, then the Company does not have to continue its obligations under Section 5.1, provided that, any such withdrawal will not count as the Demand Registration if the Demanding Holders pay all of the Company’s out-of-pocket expenses, with respect to such withdrawn registration.

5.1.6 Terms. The Company shall bear all fees and expenses attendant to registering the Registrable Securities, including the expenses of one legal counsel selected by the Holders to represent them in connection with the sale of the Registrable Securities, but the Holders shall pay any and all underwriting commissions. The Company agrees to use its reasonable best efforts to qualify or register the Registrable Securities in such states as are reasonably requested by the Majority Holder(s); provided, however, that in no event shall the Company be required to register the Registrable Securities in a state in which such registration would cause (i) the Company to be obligated to qualify to do business in such state, or would subject the Company to taxation as a foreign corporation doing business in such jurisdiction or (ii) the principal stockholders of the Company to be obligated to escrow their shares of capital stock of the Company. The Company shall use its best efforts to cause any registration statement or post-effective amendment filed pursuant to the demand rights granted under Section 5.1.1 to remain effective for a period of nine consecutive months from the effective date of such registration statement or post-effective amendment.

5.2 Piggy-Back Registration.

5.2.1 Piggy-Back Rights. If at any time during the seven year period commencing on the date of commencement of sales in the Offering, the Company proposes to file a registration statement under the Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into, equity securities, by the Company for its own account or for stockholders of the Company for their account (or by the Company and by stockholders of the Company including, without limitation, pursuant to Section 5.1), other than a registration statement (i) filed in connection with any employee stock option or other benefit plan, (ii) for an exchange offer or offering of securities solely to the Company’s existing stockholders, (iii) for an offering of debt that is convertible into equity securities of the Company or (iv) for a dividend reinvestment plan, then the Company shall (x) give written notice of such proposed filing to the holders of Registrable Securities as soon as practicable but in no event less than ten (10) days before the anticipated filing date, which notice shall describe the amount and type of securities to be included in such offering, the intended method(s) of distribution, and the name of the proposed managing underwriter or underwriters, if any, of the offering, and (y) offer to the holders of Registrable Securities in such notice the opportunity to register the sale of such number of shares of Registrable Securities as such holders may request in writing within five (5) days following receipt of such notice (a “Piggy-Back Registration”). The Company shall cause such Registrable Securities to be included in such registration and shall use its best efforts to cause the managing underwriter or underwriters of a proposed underwritten offering to permit the Registrable Securities requested to be included in a Piggy-Back Registration on the same terms and conditions as any similar securities of the Company and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. All holders of Registrable Securities proposing to distribute their securities through a Piggy-Back Registration that involves an underwriter or underwriters shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such Piggy-Back Registration

5.2.2 Reduction of Offering. If the managing underwriter or underwriters for a Piggy-Back Registration that is to be an underwritten offering advises the Company and the holders of Registrable Securities in writing that the dollar amount or number of Shares which the Company desires to sell, taken together with Shares, if any, as to which registration has been demanded pursuant to written contractual arrangements with persons other than the holders of Registrable Securities hereunder, the Registrable Securities as to which registration has been requested under this Section 5.2, and the Shares, if any, as to which registration has been requested pursuant to the written contractual piggy-back registration rights of other stockholders of the Company, exceeds the Maximum Number of Shares, then the Company shall include in any such registration:

(a) If the registration is undertaken for the Company’s account: (A) first, Shares or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number of Shares; (B) second, to the extent that the Maximum Number of Shares has not been reached under the foregoing clause (A), the Shares or other securities, if any, comprised of Registrable Securities and Investor Securities, as to which registration has been requested pursuant to the applicable written contractual piggy-back registration rights of such security holders, Pro Rata, that can be sold without exceeding the Maximum Number of Shares; and (C) third, to the extent that the Maximum Number of shares has not been reached under the foregoing clauses (A) and (B), the Shares or other securities for the account of other persons that the Company is obligated to register pursuant to written contractual piggy-back registration rights with such persons and that can be sold without exceeding the Maximum Number of Shares;

(c) If the registration is a “demand” registration undertaken at the demand of persons other than either the holders of Registrable Securities or of Investor Securities, (A) first, the Shares or other securities for the account of the demanding persons that can be sold without exceeding the Maximum Number of Shares; (B) second, to the extent that the Maximum Number of Shares has not been reached under the foregoing clause (A), the Shares or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number of Shares; (C) third, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (A) and (B), collectively the Shares or other securities comprised of Registrable Securities and Investor Securities, Pro Rata, as to which registration has been requested pursuant to the terms hereof and of the Registration Rights Agreement, as applicable, that can be sold without exceeding the Maximum Number of Shares; and (D) fourth, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (A), (B) and (C), the Shares or other securities for the account of other persons that the Company is obligated to register pursuant to written contractual arrangements with such persons, that can be sold without exceeding the Maximum Number of Shares.

5.2.3 Withdrawal. Any holder of Registrable Securities may elect to withdraw such holder’s request for inclusion of Registrable Securities in any Piggy-Back Registration by giving written notice to the Company of such request to withdraw prior to the effectiveness of the registration statement. The Company (whether on its own determination or as the result of a withdrawal by persons making a demand pursuant to written contractual obligations) may withdraw a registration statement at any time prior to the effectiveness of the registration statement. Notwithstanding any such withdrawal, the Company shall pay all expenses incurred by the holders of Registrable Securities in connection with such Piggy-Back Registration as provided in Section 5.2.4.

5.2.4 Terms. The Company shall bear all fees and expenses attendant to registering the Registrable Securities, including the expenses of one legal counsel selected by the Holders to represent them in connection with the sale of the Registrable Securities but the Holders shall pay any and all underwriting commissions related to the Registrable Securities. In the event of such a proposed registration, the Company shall furnish the then Holders of outstanding Registrable Securities with not less than fifteen days written notice prior to the proposed date of filing of such registration statement. Such notice to the Holders shall continue to be given for each applicable registration statement filed (during the period in which this Purchase Option is exercisable) by the Company until such time as all of the Registrable Securities have been registered and sold. The Holders of the Registrable Securities shall exercise the “piggy-back” rights provided for herein by giving written notice within ten days of the receipt of the Company’s notice of its intention to file a registration statement. The Company shall use its best efforts to cause any registration statement filed pursuant to the above “piggyback” rights to remain effective for at least nine months from the date that the Holders of the Registrable Securities are first given the opportunity to sell all of such securities.

5.3 General Terms.

5.3.1 Indemnification. The Company shall, to the fullest extent permitted by applicable law, indemnify the Holder(s) of the Registrable Securities to be sold pursuant to any registration statement hereunder and each person, if any, who controls such Holders within the meaning of Section 15 of the Act or Section 20(a) of the Securities Exchange Act of 1934, as amended (“Exchange Act”), against all loss, claim, damage, expense or liability (including all reasonable attorneys’ fees and other expenses reasonably incurred in investigating, preparing or defending against litigation, commenced or threatened, or any claim whatsoever whether arising out of any action between the underwriter and the Company or between the underwriter and any third party or otherwise) to which any of them may become subject under the Act, the Exchange Act or otherwise, arising from such registration statement but only to the same extent and with the same effect as the provisions pursuant to which the Company has agreed to indemnify the underwriters contained in Section 5 of the Underwriting Agreement between the Company, Chardan and the other underwriters named therein dated [*], 2022 (“Underwriting Agreement”). The Holder(s) of the Registrable Securities to be sold pursuant to such registration statement, and their successors and assigns, shall severally, and not jointly, indemnify the Company, its officers and directors and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, against all loss, claim, damage, expense or liability (including all reasonable attorneys’ fees and other expenses reasonably incurred in investigating, preparing or defending against any claim whatsoever) to which they may become subject under the Act, the Exchange Act or otherwise, arising from information furnished by or on behalf of such Holders, or their successors or assigns, in writing, for specific inclusion in such registration statement or arising from any omission or the alleged omission to state a material fact required to be stated therein or necessary to make the statement contained therein not misleading in connection with the registration of the Registrable Securities, to the same extent and with the same effect as the provisions contained in Section 5 of the Underwriting Agreement pursuant to which the underwriters have agreed to indemnify the Company.

5.3.2 Exercise of Purchase Option. Nothing contained in this Purchase Option shall be construed as requiring the Holder(s) to exercise their Purchase Option prior to or after the initial filing of any registration statement or the effectiveness thereof.

5.3.3 Documents Delivered to Holders. The Company shall furnish Chardan, as representative of the Holders participating in any of the foregoing offerings, a signed counterpart, addressed to the participating Holders, of (i) an opinion of counsel to the Company, dated the effective date of such registration statement (and, if such registration includes an underwritten public offering, an opinion dated the date of the closing under any underwriting agreement related thereto), and (ii) a “cold comfort” letter dated the effective date of such registration statement (and, if such registration includes an underwritten public offering, a letter dated the date of the closing under the underwriting agreement) signed by the independent public accountants who have issued a report on the Company’s financial statements included in such registration statement, in each case covering substantially the same matters with respect to such registration statement (and the prospectus included therein) and, in the case of such accountants’ letter, with respect to events subsequent to the date of such financial statements, as are customarily covered in opinions of issuer’s counsel and in accountants’ letters delivered to underwriters in underwritten public offerings of securities. The Company shall also deliver promptly to Chardan, as representative of the Holders participating in the offering, the correspondence and memoranda described below and copies of all correspondence between the Commission and the Company, its counsel or auditors and all memoranda relating to discussions with the Commission or its staff with respect to the registration statement and permit Chardan, as representative of the Holders, to do such investigation, upon reasonable advance notice, with respect to information contained in or omitted from the registration statement as it deems reasonably necessary to comply with applicable securities laws or rules of FINRA. Such investigation shall include access to books, records and properties and opportunities to discuss the business of the Company with its officers and independent auditors, all to such reasonable extent and at such reasonable times and as often as Chardan, as representative of the Holders, shall reasonably request. The Company shall not be required to disclose any confidential information or other records to Chardan, as representative of the Holders, or to any other person, until and unless such persons shall have entered into reasonable confidentiality agreements (in form and substance reasonably satisfactory to the Company), with the Company with respect thereto.

5.3.4 Underwriting Agreement. The Company shall enter into an underwriting agreement with the managing underwriter(s), if any, selected by any Holders whose Registrable Securities are being registered pursuant to this Section 5, which managing underwriter shall be reasonably acceptable to the Company. Such agreement shall be reasonably satisfactory in form and substance to the Company, each Holder and such managing underwriters, and shall contain such representations, warranties and covenants by the Company and such other terms as are customarily contained in agreements of that type used by the managing underwriter. The Holders shall be parties to any underwriting agreement relating to an underwritten sale of their Registrable Securities and may, at their option, require that any or all the representations, warranties and covenants of the Company to or for the benefit of such underwriters shall also be made to and for the benefit of such Holders. Such Holders shall not be required to make any representations or warranties to or agreements with the Company or the underwriters except as they may relate to such Holders and their intended methods of distribution. Such Holders, however, shall agree to such covenants and indemnification and contribution obligations for selling stockholders as are customarily contained in agreements of that type used by the managing underwriter. Further, such Holders shall execute appropriate custody agreements and otherwise cooperate fully in the preparation of the registration statement and other documents relating to any offering in which they include securities pursuant to this Section 5. Each Holder shall also furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of disposition of such securities as shall be reasonably required to effect the registration of the Registrable Securities.

5.3.5 Rule 144 Sale. Notwithstanding anything contained in this Section 5 to the contrary, the Company shall have no obligation pursuant to Sections 5.1 or 5.2 to use its best efforts to obtain the registration of Registrable Securities held by any Holder (i) where such Holder would then be entitled to sell under Rule 144 within any three-month period (or such other period prescribed under Rule 144 as may be provided by amendment thereof) all of the Registrable Securities then held by such Holder, or (ii) where the number of Registrable Securities held by such Holder is within the volume limitations under paragraph (e) of Rule 144 (calculated as if such Holder were an affiliate within the meaning of Rule 144).

5.3.6 Supplemental Prospectus. Each Holder agrees, that upon receipt of any notice from the Company of the happening of any event as a result of which the prospectus included in the registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing, such Holder will immediately discontinue disposition of Registrable Securities pursuant to the registration statement covering such Registrable Securities until such Holder’s receipt of the copies of a supplemental or amended prospectus, and, if so desired by the Company, such Holder shall deliver to the Company (at the expense of the Company) or destroy (and deliver to the Company a certificate of such destruction) all copies, other than permanent file copies then in such Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice.

6.1 Adjustments to Exercise Price and Number of Securities. The Exercise Price and the number of Units underlying this Purchase Option shall be subject to adjustment from time to time as hereinafter set forth:

6.1.1 Stock Dividends - Split-Ups. If after the date hereof, and subject to the provisions of Section 6.3 below, the number of outstanding Shares is increased by a stock dividend payable in Shares or by a split-up of Shares or other similar event, then, on the effective date thereof, the number of Shares underlying each of the Units purchasable hereunder shall be increased in proportion to such increase in outstanding shares. In such case, the number of Shares, and the exercise price applicable thereto, underlying the Warrants underlying each of the Units purchasable hereunder shall be adjusted in accordance with the terms of the Warrants.

6.1.2 Aggregation of Shares. If after the date hereof, and subject to the provisions of Section 6.3, the number of outstanding Shares is decreased by a consolidation, combination or reclassification of Shares or other similar event, then, on the effective date thereof, the number of Shares underlying each of the Units purchasable hereunder shall be decreased in proportion to such decrease in outstanding shares and the Exercise Price shall be proportionately increased. In such case, the number of Shares, and the exercise price applicable thereto, underlying the Warrants underlying each of the Units purchasable hereunder shall be adjusted in accordance with the terms of the Warrants.

6.1.3 Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding Shares other than a change covered by Section 6.1.1 or 6.1.2 hereof or that solely affects the par value of such Shares, or in the case of any merger or consolidation of the Company with or into another company (other than a consolidation or merger in which the Company is the continuing entity and that does not result in any reclassification or reorganization of the outstanding Shares), or in the case of any sale or conveyance to another company or entity of the property of the Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the Holder of this Purchase Option shall have the right thereafter (until the expiration of the right of exercise of this Purchase Option) to receive upon the exercise hereof, for the same aggregate Exercise Price payable hereunder immediately prior to such event, the kind and amount of shares or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, by a Holder of the number of Shares of the Company obtainable upon exercise of this Purchase Option and the underlying Warrants immediately prior to such event; and if any reclassification also results in a change in Shares covered by Section 6.1.1 or 6.1.2, then such adjustment shall be made pursuant to Sections 6.1.1, 6.1.2 and this Section 6.1.3. The provisions of this Section 6.1.3 shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations, sales or other transfers.

6.1.4 Changes in Form of Purchase Option. This form of Purchase Option need not be changed because of any change pursuant to this Section, and a Purchase Option issued after such change may state the same Exercise Price and the same number of Units as are stated in this Purchase Option as initially issued. The acceptance by any Holder of the issuance of a new Purchase Option reflecting a required or permissive change shall not be deemed to waive any rights to an adjustment occurring after the Commencement Date or the computation thereof.

6.2 Substitute Purchase Option. In case of any consolidation of the Company with, or merger of the Company with, or merger of the Company into, another entity (other than a consolidation or merger which does not result in any reclassification or change of the outstanding Shares), the entity formed by such consolidation or merger shall execute and deliver to the Holder a supplemental Purchase Option providing that the holder of each Purchase Option then outstanding or to be outstanding shall have the right thereafter (until the stated expiration of such Purchase Option) to receive, upon exercise of such Purchase Option, the kind and amount of shares and other securities and property receivable upon such consolidation or merger, by a holder of the number of Shares of the Company for which such Purchase Option might have been exercised immediately prior to such consolidation, merger, sale or transfer. Such supplemental Purchase Option shall provide for adjustments which shall be identical to the adjustments provided in Section 6. The above provision of this Section shall similarly apply to successive consolidations or mergers.

6.3 Elimination of Fractional Interests. The Company shall not be required to issue certificates representing fractions of Shares, Rights, or Warrants upon the exercise of this Purchase Option, nor shall it be required to issue scrip or pay cash in lieu of any fractional interests, it being the intent of the parties that all fractional interests shall be eliminated by rounding any fraction up to the nearest whole number of Warrants, Rights, Shares or other securities, properties or rights (or as otherwise provided pursuant to the Rights Agreement).

7. RESERVATION AND LISTING. The Company shall at all times reserve and keep available out of its authorized but unissued Shares, solely for the purpose of issuance upon exercise of this Purchase Option, the Rights underlying this Purchase Option, or the Warrants, such number of Shares or other securities, properties or rights as shall be issuable upon the exercise thereof. The Company covenants and agrees that, upon exercise of this Purchase Option and payment of the Exercise Price therefor, all Shares and other securities issuable upon such exercise shall be duly and validly issued, fully paid and non-assessable and not subject to preemptive rights of any stockholder. The Company further covenants and agrees that upon conversion of the Rights underlying this Purchase Option or exercise of the Warrants underlying this Purchase Option and payment of the respective Warrant exercise price therefor, all Shares and other securities issuable upon such conversion shall be duly and validly issued, fully paid and non-assessable and not subject to preemptive rights of any stockholders. As long as this Purchase Option shall be outstanding, the Company shall use its best efforts to cause all (i) Units and Shares issuable upon exercise of this Purchase Option, (ii) Warrants issuable upon exercise of this Purchase Option, (iii) Shares issuable upon exercise of the Warrants included in the Units issuable upon exercise of this Purchase Option, (iv) Rights issuable upon exercise of this Purchase Option and (v) Shares underlying the Rights included in the Units issuable upon exercise of this Purchase Option to be listed and/or quoted (subject to official notice of issuance) on all securities exchanges (or, if applicable, on the OTC Bulletin Board or OTC Markets Group, Inc. or any successor trading market) on which the Units, Shares, Rights, or Warrants may then be listed and/or quoted.

8.1 Holder’s Right to Receive Notice. Nothing herein shall be construed as conferring upon the Holders the right to vote or consent as a stockholders for the election of directors or any other matter, or as having any rights whatsoever as a stockholders of the Company. If, however, at any time prior to the expiration of this Purchase Option and its exercise, any of the events described in Section 8.2 shall occur, then, in each such event, the Company shall give written notice of such event at least fifteen days prior to the date fixed as a record date or the date of closing the transfer books for the determination of the stockholders entitled to such dividend, distribution, conversion or exchange of securities or subscription rights, or entitled to vote on such proposed dissolution, liquidation, winding up or sale. Such notice shall specify such record date or the date of the closing of the transfer books, as the case may be. Notwithstanding the foregoing, the Company shall deliver to each Holder a copy of each notice given to the other stockholders of the Company at the same time and in the same manner that such notice is given to the stockholders.

8.2 Events Requiring Notice. The Company shall be required to give the notice described in this Section 8 upon one or more of the following events: (i) if the Company shall take a record of the holders of its Shares for the purpose of entitling them to receive a dividend or distribution payable otherwise than in cash, or a cash dividend or distribution payable otherwise than out of retained earnings, as indicated by the accounting treatment of such dividend or distribution on the books of the Company, or (ii) the Company shall offer to all the holders of its Shares any additional shares of capital stock of the Company or securities convertible into or exchangeable for shares of capital stock of the Company, or any option, right or warrant to subscribe therefor, or (iii) a dissolution, liquidation or winding up of the Company (other than in connection with a consolidation or merger) or a sale of all or substantially all of its property, assets and business shall be proposed.

8.3 Notice of Change in Exercise Price. The Company shall, promptly after an event requiring a change in the Exercise Price pursuant to Section 6 hereof, send notice to the Holders of such event and change (“Price Notice”). The Price Notice shall describe the event causing the change and the method of calculating same and shall be certified as being true and accurate by the Company’s Chief Executive Officer.

8.4 Transmittal of Notices. All notices, requests, consents and other communications under this Purchase Option shall be in writing and shall be deemed to have been duly made when hand delivered, or mailed by express mail or private courier service: (i) if to the registered Holder of this Purchase Option, to the address of such Holder as shown on the books of the Company, or (ii) if to the Company, to the following address or to such other address as the Company may designate by notice to the Holders:

9.6 Waiver, Etc.

No waiver of any breach, non-compliance or non-fulfillment of any of the provisions of this Purchase Option shall be effective unless set forth in a written instrument executed by the party or parties against whom or which enforcement of such waiver is sought; and no waiver of any such breach, non-compliance or non- fulfillment shall be construed or deemed to be a waiver of any other or subsequent breach or non-compliance.
