UNSECURED CONVERTIBLE PROMISSORY NOTE

FOR VALUE RECEIVED, ARCH THERAPEUTICS, INC., a Nevada corporation (hereinafter called the “Borrower”) (Trading Symbol: ARTH), hereby promises to pay to the order of _____, or registered assigns (the “Holder”) the sum of ______ together with any interest as set forth herein, on March 15, 2024 (the “Maturity Date”), and to pay interest on the unpaid principal balance hereof at the rate of ten percent (10%) (the “Interest Rate”) per annum from the Issue Date set forth above (the “Issue Date”) until the same becomes due and payable, whether at maturity or upon acceleration or by prepayment or otherwise, the entire amount of which interest shall be guaranteed from the Issue Date through the Maturity Date. This Note may not be prepaid in whole or in part except as otherwise explicitly set forth herein with the written consent of the Holder which may be withheld for any reason or for no reason. Any amount of principal or interest on this Note which is not paid when due shall bear interest at the rate of the lesser of (i) eighteen percent (18%) per annum or (ii) the maximum amount allowed by law from the due date thereof until the same is paid (the “Default Interest”). Interest shall commence accruing on the Issue Date and shall be computed on the basis of a 360-day year and the actual number of days elapsed. All payments due hereunder (to the extent not converted into common stock, $0.001 par value per share (the “Common Stock”) in accordance with the terms hereof) shall be made in lawful money of the United States of America. All payments shall be made at such address as the Holder shall hereafter give to the Borrower by written notice made in accordance with the provisions of this Note. Whenever any amount expressed to be due by the terms of this Note is due on any day which is not a business day, the same shall instead be due on the next succeeding day which is a business day and, in the case of any interest payment date which is not the date on which this Note is paid in full, the extension of the due date thereof shall not be taken into account for purposes of determining the amount of interest due on such date. As used in this Note, the term “business day” shall mean any day other than a Saturday, Sunday or a day on which commercial banks in the city of New York, New York are authorized or required by law or executive order to remain closed. Each capitalized term used herein, and not otherwise defined, shall have the meaning ascribed thereto in that certain Securities Purchase Agreement dated as of July 6, 2022, as amended on January 18, 2023, May 15, 2023 and March 12, 2024, pursuant to which this Note was originally issued (the “Purchase Agreement”).

This Note is free from all taxes, liens, claims and encumbrances with respect to the issue thereof and shall not be subject to preemptive rights or other similar rights of shareholders of the Borrower and will not impose personal liability upon the holder thereof.

The following terms shall also apply to this Note:

ARTICLE I.  CONVERSION RIGHTS

1.1    Conversion Right. The Holder shall have the right from time to time, and at any time on or following the Issue Date and ending on the later of (i) the Maturity Date and (ii) the date of payment of the Default Amount (as defined in Article III) pursuant to Section 1.6(a) or Article III, each in respect of the remaining outstanding principal amount of this Note to convert all or any part of the outstanding and unpaid principal amount of this Note into fully paid and non-assessable shares of Common Stock, as such Common Stock exists on the Issue Date, or any shares of capital stock or other securities of the Borrower into which such Common Stock shall hereafter be changed or reclassified at the Conversion Price (as defined below) determined as provided herein (a “Conversion”); provided, however, that in no event shall the Holder be entitled to convert any portion of this Note in excess of that portion of this Note upon conversion of which the sum of (1) the number of shares of Common Stock beneficially owned by the Holder and its affiliates (other than shares of Common Stock which may be deemed beneficially owned through the ownership of the unconverted portion of the Notes or the unexercised or unconverted portion of any other security of the Borrower subject to a limitation on conversion or exercise analogous to the limitations contained herein) and (2) the number of shares of Common Stock issuable upon the conversion of the portion of this Note with respect to which the determination of this proviso is being made, would result in beneficial ownership by the Holder and its affiliates of more than 4.99% of the outstanding shares of Common Stock. For purposes of the proviso to the immediately preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Regulations 13D-G thereunder, except as otherwise provided in clause (1) of such proviso, provided, further, however, that the limitations on conversion may be waived by the Holder (up to a maximum of 9.99%) upon, at the election of the Holder, not less than 61 days’ prior notice to the Borrower, and the provisions of the conversion limitation shall continue to apply until such 61st day (or such later date, as determined by the Holder, as may be specified in such notice of waiver). The number of shares of Common Stock to be issued upon each conversion of this Note shall be determined by dividing the Conversion Amount (as defined below) by the applicable Conversion Price then in effect on the date specified in the notice of conversion, in the form attached hereto as Exhibit A (the “Notice of Conversion”), delivered to the Borrower by the Holder in accordance with Section 1.4 below; provided that the Notice of Conversion is submitted by facsimile or e-mail (or by other means resulting in, or reasonably expected to result in, notice) to the Borrower before 11:59 p.m., New York, New York time on such conversion date (the “Conversion Date”). The term “Conversion Amount” means, with respect to any conversion of this Note, the sum of (1) the principal amount of this Note to be converted in such conversion plus (2) at the Holder’s option, accrued and unpaid interest, if any, on such principal amount at the interest rates provided in this Note to the Conversion Date, provided however, that the Borrower shall have the right to pay any or all interest in cash plus (3) at the Holder’s option, Default Interest, if any, on the amounts referred to in the immediately preceding clauses (1) and/or (2) plus (4) at the Holder’s option, any amounts owed to the Holder pursuant to Sections 1.3 and 1.4(g) hereof.

1.2    Conversion Price. Subject to the adjustments described herein, the conversion price (the “Conversion Price”) shall equal $9.14. If the shares of the Borrower’s Common Stock have not been delivered within three (3) business days to the Borrower, the Notice of Conversion may be rescinded. At any time after the Closing Date, if in the case that the Borrower’s Common Stock is not deliverable by DWAC (including if the Borrower’s transfer agent has a policy prohibiting or limiting delivery of shares of the Borrower’s Common Stock specified in a Notice of Conversion), the Borrower shall pay to the Holder $1,000 per each Trading Day following the Closing Date that any such limitation or prohibition exists. If in the case that the Borrower’s Common Stock is “chilled” for deposit into the DTC system and only eligible for clearing deposit, an additional $1,000 per each Trading Day shall be payable while the “chill” is in effect. Additionally, if the Borrower ceases to be a reporting company pursuant to the 1934 Act or if the Note cannot be converted into free trading shares after one hundred eighty-one (181) days from the Issue Date, an additional $1,000 per Trading Day shall be payable. “Trading Day” shall mean any day on which the Common Stock is tradable for any period on the OTC Pink, OTCQB or on the principal securities exchange or other securities market on which the Common Stock is then being traded. The Borrower shall be responsible for the fees of its transfer agent and all DTC fees associated with any such issuance. Holder shall be entitled to deduct up to $500.00 from the conversion amount in each Notice of Conversion to cover Holder’s deposit fees associated with each Notice of Conversion. In the event of a dispute as to the number of shares of Common Stock issuable to the Holder in connection with a conversion of this Note, the Borrower shall issue to the Holder the number of shares of Common Stock not in dispute and resolve such dispute in accordance with Section 4.13.

1.3    Authorized Shares. The Borrower covenants that during the period the conversion right exists, the Borrower will reserve from its authorized and unissued Common Stock a sufficient number of shares, free from preemptive rights, to provide for the issuance of Common Stock upon the full conversion of this Note issued pursuant to the Purchase Agreement in an amount of at least the Reserved Amount (as defined below). The Borrower is required at all times to have authorized and reserved one and a half (1.5) times the number of shares that is actually issuable upon full conversion of the Note (based on the Conversion Price of the Notes in effect from time to time) (the “Reserved Amount”) such that the aggregate amount so reserved for all Notes combined is one and a half (1.5) times the amount needed for all such Notes. The Reserved Amount shall be increased from time to time in accordance with the Borrower’s obligations pursuant to Section 3(d) of the Purchase Agreement. The Borrower represents that upon issuance, such shares will be duly and validly issued, fully paid and non-assessable. In addition, if the Borrower shall issue any securities or make any change to its capital structure which would change the number of shares of Common Stock into which the Notes shall be convertible at the then current Conversion Price, the Borrower shall at the same time make proper provision so that thereafter there shall be a sufficient number of shares of Common Stock authorized and reserved, free from preemptive rights, for conversion of the outstanding Notes, in an amount of at least the Reserved Amount. The Borrower (i) acknowledges that it has irrevocably instructed its transfer agent to issue certificates for the Common Stock issuable upon conversion of this Note, and (ii) agrees that its issuance of this Note shall constitute full authority to its officers and agents who are charged with the duty of executing stock certificates to execute and issue the necessary certificates for shares of Common Stock in accordance with the terms and conditions of this Note.

If, at any time the Borrower does not maintain or replenish the Reserved Amount within three (3) business days of the written request of the Holder, the principal amount of the Note shall increase by thirty percent (30%) (under Holder’s and Borrower’s expectation that any principal amount increase will tack back to the Issue Date).

1.4      Method of Conversion.

(a)    Mechanics of Conversion. Subject to Section 1.1, this Note may be converted by the Holder in whole or in part at any time from time to time on or after the Issue Date, by (A) submitting to the Borrower a Notice of Conversion (by facsimile, e-mail or other reasonable means of communication dispatched on the Conversion Date prior to 11:59 p.m., New York, New York time) and (B) subject to Section 1.4(b), surrendering this Note at the principal office of the Borrower.

(b)    Surrender of Note Upon Conversion. Notwithstanding anything to the contrary set forth herein, upon conversion of this Note in accordance with the terms hereof, the Holder shall not be required to physically surrender this Note to the Borrower unless the entire unpaid principal amount of this Note is so converted. The Holder and the Borrower shall maintain records showing the principal amount so converted and the dates of such conversions or shall use such other method, reasonably satisfactory to the Holder and the Borrower, so as not to require physical surrender of this Note upon each such conversion. In the event of any dispute or discrepancy, such records of the Borrower shall, prima facie, be controlling and determinative in the absence of manifest error. Notwithstanding the foregoing, if any portion of this Note is converted as aforesaid, the Holder may not transfer this Note unless the Holder first physically surrenders this Note to the Borrower, whereupon the Borrower will forthwith issue and deliver upon the order of the Holder a new Note of like tenor, registered as the Holder (upon payment by the Holder of any applicable transfer taxes) may request, representing in the aggregate the remaining unpaid principal amount of this Note. The Holder and any assignee, by acceptance of this Note, acknowledge and agree that, by reason of the provisions of this paragraph, following conversion of a portion of this Note, the unpaid and unconverted principal amount of this Note represented by this Note may be less than the amount stated on the face hereof.

(c)    Payment of Taxes. The Borrower shall not be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock or other securities or property on conversion of this Note in a name other than that of the Holder (or in street name), and the Borrower shall not be required to issue or deliver any such shares or other securities or property unless and until the person or persons (other than the Holder or the custodian in whose street name such shares are to be held for the Holder’s account) requesting the issuance thereof shall have paid to the Borrower the amount of any such tax or shall have established to the satisfaction of the Borrower that such tax has been paid.

(d)    Delivery of Common Stock Upon Conversion. Upon receipt by the Borrower from the Holder of a facsimile transmission or e-mail (or other reasonable means of communication) of a Notice of Conversion meeting the requirements for conversion as provided in this Section 1.4, the Borrower shall issue and deliver or cause to be issued and delivered to or upon the order of the Holder certificates for the Common Stock issuable upon such conversion within two (2) business days after such receipt (the “Deadline”) (and, solely in the case of conversion of the entire unpaid principal amount hereof, surrender of this Note) in accordance with the terms hereof and the Purchase Agreement.

(e)    Obligation of Borrower to Deliver Common Stock. Upon receipt by the Borrower of a Notice of Conversion, the Holder shall be deemed to be the holder of record of the Common Stock issuable upon such conversion, the outstanding principal amount and the amount of accrued and unpaid interest on this Note shall be reduced to reflect such conversion, and, unless the Borrower defaults on its obligations under this Article I, all rights with respect to the portion of this Note being so converted shall forthwith terminate except the right to receive the Common Stock or other securities, cash or other assets, as herein provided, on such conversion. If the Holder shall have given a Notice of Conversion as provided herein, the Borrower’s obligation to issue and deliver the certificates for Common Stock shall be absolute and unconditional, irrespective of the absence of any action by the Holder to enforce the same, any waiver or consent with respect to any provision thereof, the recovery of any judgment against any person or any action to enforce the same, any failure or delay in the enforcement of any other obligation of the Borrower to the holder of record, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder of any obligation to the Borrower, and irrespective of any other circumstance which might otherwise limit such obligation of the Borrower to the Holder in connection with such conversion. The Conversion Date specified in the Notice of Conversion shall be the Conversion Date so long as the Notice of Conversion is received by the Borrower before 11:59 p.m., New York, New York time, on such date.

(f)    Delivery of Common Stock by Electronic Transfer. In lieu of delivering physical certificates representing the Common Stock issuable upon conversion, provided the Borrower is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer (“FAST”) program, upon request of the Holder and its compliance with the provisions contained in Section 1.1 and in this Section 1.4, the Borrower shall use its commercially reasonable best efforts to cause its transfer agent to electronically transmit the Common Stock issuable upon conversion to the Holder by crediting the account of Holder’s Prime Broker with DTC through its Deposit Withdrawal At Custodian (“DWAC”) system.

(g)    DTC Eligibility & Market Loss. If the Borrower fails to maintain its status as “DTC Eligible” for any reason, or, if the Conversion Price is less than $0.01 at any time after the Issue Date, the principal amount of the Note shall increase by twenty percent (20%) (under Holder’s and Borrower’s expectation that any principal amount increase will tack back to the Issue Date).

(h)    Failure to Deliver Common Stock Prior to Delivery Deadline. Without in any way limiting the Holder’s right to pursue other remedies, including actual damages and/or equitable relief, the parties agree that if delivery of the Common Stock issuable upon conversion of this Note is not delivered by the Deadline (other than a failure due to the circumstances described in Section 1.3 above, which failure shall be governed by such Section) the Borrower shall pay to the Holder $5,000 per day in cash, for each day beyond the Deadline that the Borrower fails to deliver such Common Stock until the Borrower issues and delivers a certificate to the Holder or credit the Holder’s balance account with OTC for the number of shares of Common Stock to which the Holder is entitled upon such Holder’s conversion of any Conversion Amount (under Holder’s and Borrower’s expectation that any damages will tack back to the Issue Date). Such cash amount shall be paid to Holder by the fifth day of the month following the month in which it has accrued or, at the option of the Holder (by written notice to the Borrower by the first day of the month following the month in which it has accrued), shall be added to the principal amount of this Note, in which event interest shall accrue thereon in accordance with the terms of this Note and such additional principal amount shall be convertible into Common Stock in accordance with the terms of this Note. The Borrower agrees that the right to convert is a valuable right to the Holder. The damages resulting from a failure, attempt to frustrate, interference with such conversion right are difficult if not impossible to qualify. Accordingly, the parties acknowledge that the liquidated damages provision contained in this Section 1.4(h) are justified.

(i)    Rescindment of a Notice of Conversion. If (i) the Borrower fails to respond to Holder within one (1) business day from the Conversion Date confirming the details of Notice of Conversion, (ii) the Borrower fails to provide any of the shares of the Borrower’s Common Stock requested in the Notice of Conversion within two (2) business days from the date of receipt of the Note of Conversion, (iii) if the Holder provides standard and customary documentation, the Holder is unable to procure a legal opinion required to have the shares of the Borrower’s Common Stock issued unrestricted and/or deposited to sell for any reason related to the Borrower’s standing, (iv) the Holder is unable to deposit the shares of the Borrower’s Common Stock requested in the Notice of Conversion for any reason related to the Borrower’s standing, other than restrictions under Rule 144, (v) at any time after a missed Deadline, at the Holder’s sole discretion, or (vi) if OTC Markets changes the Borrower’s designation to ‘Limited Information’ (Yield), ‘No Information’ (Stop Sign), ‘Caveat Emptor’ (Skull & Crossbones), ‘OTC’, ‘Other OTC’ or ‘Grey Market’ (Exclamation Mark Sign) or other trading restriction on the day of or any day after the Conversion Date, the Holder maintains the option and sole discretion to rescind the Notice of Conversion (“Rescindment”) with a “Notice of Rescindment.” For the avoidance of doubt, no delivery of a Notice of Rescindment shall be deemed to be a waiver of any failure to deliver shares under a Notice of Conversion, has such Notice of Rescindment not otherwise been delivered.

1.5      Concerning the Shares. The shares of Common Stock issuable upon conversion of this Note may not be sold or transferred unless (i) such shares are sold pursuant to an effective registration statement under the Act or (ii) the Borrower or its transfer agent shall have been furnished with an opinion of counsel (which opinion shall be in form, substance and scope customary for opinions of counsel in comparable transactions) to the effect that the shares to be sold or transferred may be sold or transferred pursuant to an exemption from such registration or (iii) such shares are sold or transferred pursuant to Rule 144 under the Act (or a successor rule) (“Rule 144”) or (iv) such shares are transferred to an “affiliate” (as defined in Rule 144) of the Borrower who agrees to sell or otherwise transfer the shares only in accordance with this Section 1.5 and who is an Accredited Investor (as defined in the Purchase Agreement). Except as otherwise provided in the Purchase Agreement (and subject to the removal provisions set forth below), until such time as the shares of Common Stock issuable upon conversion of this Note have been registered under the Act or otherwise may be sold pursuant to Rule 144 without any restriction as to the number of securities as of a particular date that can then be immediately sold, each certificate for shares of Common Stock issuable upon conversion of this Note that has not been so included in an effective registration statement or that has not been sold pursuant to an effective registration statement or an exemption that permits removal of the legend, shall bear a legend substantially in the following form, as appropriate:

The legend set forth above shall be removed and the Borrower shall issue to the Holder a new certificate therefore free of any transfer legend if (i) the Borrower or its transfer agent shall have received an opinion of counsel, in form, substance and scope customary for opinions of counsel in comparable transactions, to the effect that a public sale or transfer of such Common Stock may be made without registration under the Act, which opinion shall be reasonably accepted by the Borrower so that the sale or transfer is effected or (ii) in the case of the Common Stock issuable upon conversion of this Note, such security is registered for sale by the Holder under an effective registration statement filed under the Act or otherwise may be sold pursuant to Rule 144 without any restriction as to the number of securities as of a particular date that can then be immediately sold and in each of (i) and (ii) the Borrower shall have a reasonable expectation that the Holder intends to use its commercially reasonable efforts to promptly sell or transfer such Common Stock. In the event that the Borrower does not accept the opinion of counsel provided by the Buyer with respect to the transfer of Securities pursuant to an exemption from registration (provided that such opinion is in a form standard and customary for transactions of such type), such as Rule 144 or Regulation S, at the Deadline, it will be considered an Event of Default pursuant to Section 3.2 of the Note.

1.6    Effect of Certain Events.

(a)    Effect of Merger, Consolidation, Etc. At the option of the Holder, the sale, conveyance or disposition of all or substantially all of the assets of the Borrower, the effectuation by the Borrower of a transaction or series of related transactions in which more than 50% of the voting power of the Borrower is disposed of, or the consolidation, merger or other business combination of the Borrower with or into any other Person (as defined below) or Persons when the Borrower is not the survivor then: (i) the Note shall be prepaid in full, including any prepayment penalty then due or (ii) the Note shall be treated pursuant to Section 1.6(b) hereof. “Person” shall mean any individual, corporation, limited liability company, partnership, association, trust or other entity or organization.

(b)    Adjustment Due to Merger, Consolidation, Etc. If, at any time when this Note is issued and outstanding and prior to conversion of all of the Notes, there shall be any merger, consolidation, exchange of shares, recapitalization, reorganization, or other similar event, as a result of which shares of Common Stock of the Borrower shall be changed into the same or a different number of shares of another class or classes of stock or securities of the Borrower or another entity, or in case of any sale or conveyance of all or substantially all of the assets of the Borrower other than in connection with a plan of complete liquidation of the Borrower, then the Holder of this Note shall thereafter have the right to receive upon conversion of this Note, upon the basis and upon the terms and conditions specified herein and in lieu of the shares of Common Stock immediately theretofore issuable upon conversion, such stock, securities or assets which the Holder would have been entitled to receive in such transaction had this Note been converted in full immediately prior to such transaction (without regard to any limitations on conversion set forth herein), and in any such case appropriate provisions shall be made with respect to the rights and interests of the Holder of this Note to the end that the provisions hereof (including, without limitation, provisions for adjustment of the Conversion Price and of the number of shares issuable upon conversion of the Note) shall thereafter be applicable, as nearly as may be practicable in relation to any securities or assets thereafter deliverable upon the conversion hereof. The Borrower shall not affect any transaction described in this Section 1.6(b) unless (a) it first gives fifteen (15) days’ prior written notice of the record date of the special meeting of shareholders to approve, or if there is no such record date, the consummation of, such merger, consolidation, exchange of shares, reorganization or other similar event or sale of assets (during which time the Holder shall be entitled to convert this Note) and (b) the resulting successor or acquiring entity (if not the Borrower) assumes by written instrument the obligations of this Section 1.6(b). The above provisions shall similarly apply to successive consolidations, mergers, sales, transfers or share exchanges.

(c)    Adjustment Due to Distribution. If the Borrower shall declare or make any distribution of its assets (or rights to acquire its assets) to holders of Common Stock as a dividend, stock repurchase, by way of return of capital or otherwise (including any dividend or distribution to the Borrower’s shareholders in cash or shares (or rights to acquire shares) of capital stock of a subsidiary (i.e., a spin-off)) (a “Distribution”), then the Holder of this Note shall be entitled, upon any conversion of this Note after the date of record for determining shareholders entitled to such Distribution, to receive the amount of such assets which would have been payable to the Holder with respect to the shares of Common Stock issuable upon such conversion had such Holder been the holder of such shares of Common Stock on the record date for the determination of shareholders entitled to such Distribution.

(d)    Reserved.

(e)    Purchase Rights. If, at any time when any Notes are issued and outstanding, the Borrower issues any convertible securities or rights to purchase stock, warrants, securities or other property (the “Purchase Rights”) pro rata to the record holders of any class of Common Stock, then the Holder of this Note will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which such Holder could have acquired if such Holder had held the number of shares of Common Stock acquirable upon complete conversion of this Note (without regard to any limitations on conversion contained herein) 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 Common Stock are to be determined for the grant, issue or sale of such Purchase Rights.

(f)    Notice of Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion Price as a result of the events described in this Section 1.6, the Borrower, at its expense, shall promptly compute such adjustment or readjustment and prepare and furnish to the Holder a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Borrower shall, upon the written request at any time of the Holder, furnish to such Holder a like certificate setting forth (i) such adjustment or readjustment, (ii) the Conversion Price at the time in effect and (iii) the number of shares of Common Stock and the amount, if any, of other securities or property which at the time would be received upon conversion of the Note.

1.7    Reserved.

1.8    Status as Shareholder. Upon submission of a Notice of Conversion by a Holder, (i) the shares covered thereby (other than the shares, if any, which cannot be issued because their issuance would exceed such Holder’s allocated portion of the Reserved Amount or Maximum Share Amount) shall be deemed converted into shares of Common Stock and (ii) the Holder’s rights as a Holder of such converted portion of this Note shall cease and terminate, excepting only the right to receive certificates for such shares of Common Stock and to any remedies provided herein or otherwise available at law or in equity to such Holder because of a failure by the Borrower to comply with the terms of this Note. Notwithstanding the foregoing, if a Holder has not received certificates for all shares of Common Stock prior to the tenth (10th) business day after the expiration of the Deadline with respect to a conversion of any portion of this Note for any reason, then (unless the Holder otherwise elects to retain its status as a holder of Common Stock by so notifying the Borrower) the Holder shall regain the rights of a Holder of this Note with respect to such unconverted portions of this Note and the Borrower shall, as soon as practicable, return such unconverted Note to the Holder or, if the Note has not been surrendered, adjust its records to reflect that such portion of this Note has not been converted. In all cases, the Holder shall retain all of its rights and remedies (including, without limitation, (i) the right to receive Conversion Default Payments pursuant to Section 1.3 to the extent required thereby for such Conversion Default and any subsequent Conversion Default and (ii) the right to have the Conversion Price with respect to subsequent conversions determined in accordance with Section 1.3) for the Borrower’s failure to convert this Note.

1.9        Prepayment. Subject to the terms of this Note, with the prior written approval of the Lead Investor which shall not be unreasonably withheld or delayed and provided that an Event of Default has not occurred under this Note, the Borrower may prepay the amounts outstanding hereunder pursuant to the following terms and conditions:

(a)    At any time during the period beginning on the Issue Date and ending on the date which is sixty (60) calendar days following the Issue Date, the Borrower shall have the right, exercisable on not less than three (3) Trading Days prior written notice to the Holder of the Note to prepay the outstanding Note (principal and accrued interest), in full by making a payment to the Holder of an amount in cash equal to 110%, multiplied by the sum of: (w) the then outstanding principal amount of this Note plus (x) accrued and unpaid interest on the unpaid principal amount of this Note plus (y) Default Interest, if any.

(b)    At any time during the period beginning on the date which is sixty one (61) calendar days from the Issue Date and ending on the date which is ninety (90) calendar days following the Issue Date, the Borrower shall have the right, exercisable on not less than three (3) Trading Days prior written notice to the Holder of the Note to prepay the outstanding Note (principal and accrued interest), in full by making a payment to the Holder of an amount in cash equal to 115%, multiplied by the sum of: (w) the then outstanding principal amount of this Note plus (x) accrued and unpaid interest on the unpaid principal amount of this Note plus (y) Default Interest, if any.

(c)    At any time during the period beginning on the date which is ninety one (91) calendar days from the Issue Date and ending on the date five (5) business days prior to the Maturity Date, the Borrower shall have the right, exercisable on not less than three (3) Trading Days prior written notice to the Holder of the Note to prepay the outstanding Note (principal and accrued interest), in full by making a payment to the Holder of an amount in cash equal to 120%, multiplied by the sum of: (w) the then outstanding principal amount of this Note plus (x) accrued and unpaid interest on the unpaid principal amount of this Note plus (y) Default Interest, if any.

(d)    No consent of the Lead Investor shall be required upon a prepayment made from the proceeds of an Uplist transaction (as defined below). The parties acknowledge that the Note may also be converted by the Holder to Common Stock concurrent with the Uplist transaction.

1.10    Any notice of prepayment hereunder (an “Optional Prepayment Notice”) shall be delivered to the Holder of the Note at its registered addresses by physical mail and shall state: (1) that the Borrower is exercising its right to prepay the Note, and (2) the date of prepayment which shall be not less than five (5) Trading Days and not more than ten (10) Trading Days from the date of the Optional Prepayment Notice; provided that no prepayment hereunder shall be made without the prior written consent of the Lead Investor. On the date fixed for prepayment (the “Optional Prepayment Date”), the Borrower shall make payment of the applicable prepayment amount to or upon the order of the Holder as specified by the Holder in writing to the Borrower. If the Borrower delivers an Optional Prepayment Notice and fails to pay the applicable prepayment amount due to the Holder of the Note within two (2) business days following the Optional Prepayment Date, the Borrower shall forever forfeit its right to prepay the Note pursuant to Section 1.9. Notwithstanding the foregoing, subject to the beneficial ownership limitations set forth in Section 1.1, nothing in this Section 1.10 or in Section 1.9 shall be deemed to limit the ability of the Holder to convert any portion of this Note or submit a Notice of Conversion prior to any Optional Prepayment Date.

ARTICLE II.  CERTAIN COVENANTS

2.1    Distributions on Capital Stock. So long as the Borrower shall have any obligation under this Note, the Borrower shall not without the Holder’s written consent (a) pay, declare or set apart for such payment, any dividend or other distribution (whether in cash, property or other securities) on shares of capital stock other than dividends on shares of Common Stock solely in the form of additional shares of Common Stock or (b) directly or indirectly or through any subsidiary make any other payment or distribution in respect of its capital stock except for distributions pursuant to any shareholders’ rights plan which is approved by a majority of the Borrower’s disinterested directors.

2.2    Restriction on Stock Repurchases. So long as the Borrower shall have any obligation under this Note, the Borrower shall not without the Holder’s written consent redeem, repurchase or otherwise acquire (whether for cash or in exchange for property or other securities or otherwise) in any one transaction or series of related transactions any shares of capital stock of the Borrower or any warrants, rights or options to purchase or acquire any such shares.

2.3    Borrowings. So long as the Borrower shall have any obligation under this Note, the Borrower shall not, without the Holder’s written consent, create, incur, assume guarantee, endorse, contingently agree to purchase or otherwise become liable upon the obligation of any person, firm, partnership, joint venture or corporation, except by the endorsement of negotiable instruments for deposit or collection, or suffer to exist any liability for borrowed money, except (a) borrowings in existence or committed on the date hereof and of which the Borrower has informed Holder in writing prior to the date hereof, (b) indebtedness to trade creditors financial institutions or other lenders incurred in the ordinary course of business or (c) borrowings in respect of indebtedness which is fully subordinated to the obligations of the Company and its Subsidiaries under the Transaction Documents (“Permitted Indebtedness”).

2.4    Sale of Assets. So long as the Borrower shall have any obligation under this Note, the Borrower shall not, without the Holder’s written consent, sell, lease or otherwise dispose of any significant portion of its assets outside the ordinary course of business. Any consent to the disposition of any assets shall be conditioned on a specified use of the proceeds towards the repayment of this Note.

2.5    Advances and Loans. So long as the Borrower shall have any obligation under this Note, the Borrower shall not, without the Holder’s written consent, lend money, give credit or make advances to any person, firm, joint venture or corporation, including, without limitation, officers, directors, employees, subsidiaries and affiliates of the Borrower, except loans, credits or advances (a) in existence or committed on the date hereof and which the Borrower has informed Holder in writing prior to the date hereof, (b) made in the ordinary course of business or (c) not in excess of $100,000.

2.6    Section 3(a)(10) Transaction. So long as this Note is outstanding, the Borrower shall not enter into any transaction or arrangement structured in accordance with, based upon, or related or pursuant to, in whole or in part, Section 3(a)(l0) of the Securities Act (a “3(a)(l0) Transaction”). In the event that the Borrower does enter into, or makes any issuance of Common Stock related to a 3(a)(l0) Transaction while this note is outstanding, a liquidated damages charge of 25% of the outstanding principal balance of this Note, but not less than Fifteen Thousand Dollars $15,000, will be assessed and will become immediately due and payable to the Holder at its election in the form of cash payment or addition to the balance of this Note.

2.7    Preservation of Existence, etc. The Borrower shall maintain and preserve, and cause each of its Subsidiaries to maintain and preserve, its existence, rights and privileges, and become or remain, and cause each of its Subsidiaries (other than dormant Subsidiaries that have no or minimum assets) to become or remain, duly qualified and in good standing in each jurisdiction in which the character of the properties owned or leased by it or in which the transaction of its business makes such qualification necessary.

2.8    Non-circumvention. The Borrower hereby covenants and agrees that the Borrower will not, by amendment of its Certificate or Articles of Incorporation or 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 Note, and will at all times in good faith carry out all the provisions of this Note and take all action as may be required to protect the rights of the Holder.

2.9    Events Upon Uplist. While any portion of this Note is outstanding, in the event of the listing of the Common Stock on any of the Nasdaq Global Market, Nasdaq Capital Market, New York Stock Exchange or NYSE American (the “Uplist”), simultaneously upon the closing of the offering conducted in conjunction with the Uplist (such offering, the “Uplist Transaction”), fifty percent (50%) of the then outstanding Principal Amount of this Note shall automatically convert (the “Automatic Conversion”) into shares of Common Stock, with the Conversion Price for purposes of such Automatic Conversion being equal to $0.50 (subject to adjustment for stock splits and similar transactions occurring after the date of the execution of this Amendment) per share. Furthermore, the Borrower shall give the Holder at least five business days prior notice identifying the date of closing of the Uplist Transaction. Notwithstanding the foregoing, if the Holder owns more than one Convertible Note, unless it elects otherwise by notice to the Borrower prior the Automatic Conversion, the aggregate amount to be converted in the Automatic Conversion for all such Convertible Notes of the Holder combined will be allocated among such Convertible Notes in inverse order of when they were issued (such that the most recently issued Convertible Note is converted in full before any portion of the next-most-recently issued Convertible Note is converted, and so on until such aggregate amount to be converted has been converted).

In addition, upon the Automatic Conversion, the Holder shall receive a warrant (the “Uplist Conversion Warrant”) to purchase a number of shares of Common Stock equal to 51.0496 (subject to adjustment for stock splits (which, for the avoidance of doubt, in the case of a reverse stock split, would cause such number to decrease by dividing such number by the reverse stock split factor) and similar transactions occurring after the date of the execution of this Amendment) times the dollar amount under this Note that was converted in the Automatic Conversion. The Uplist Conversion Warrant shall have an exercise price equal to $0.50 (subject to adjustment for stock splits and similar transactions occurring after the date of the execution of this Amendment) per share and shall otherwise be identical to the warrants (other than pre-funded warrants) issued pursuant to the Securities Purchase Agreement dated as of November 8, 2023 (the “Uplist PIPE”). Upon the issuance of the Uplist Conversion Warrant to the Holder, all interest payable under this Note shall have been deemed paid, and no other interest shall be due or payable hereunder. The Company shall file, no later than sixty (60) days after the closing of the Uplist Transaction, a registration statement on Form S-4, or other appropriate form, registering the offer by the Company to exchange (and the Company shall in turn offer to exchange), on a one-for-one basis, all outstanding Uplist Conversion Warrants and Other Warrants (as defined below) for newly issued warrants identical to the warrants that will be sold in the Uplist Transaction accompanying the shares of Common Stock (or share equivalents) being sold in the Uplist Transaction (except that the exercise price shall remain the same as the exercise price specified above), which warrants are expected to be listed on the Nasdaq Capital Market under the symbol “ARTHW.” As used herein, “Other Warrants” means and includes: (x) all warrants issued pursuant to the Securities Purchase Agreement; (y) all warrants (other than pre-funded warrants) issued in the Uplist PIPE; and (z) the Exchange Warrants (as defined in the Bridge Purchase Agreement (as defined below)). Such registration statement and exchange offer shall allow each holder of a Uplist Conversion Warrant or Other Warrant to participate in such exchange and receive, no later than the earlier of (a) 60th calendar day following the date of the registration statement filing and (b) the fifth trading day following the date on which the Company is notified by the U.S. Securities and Exchange Commission that the registration statement will not be reviewed or is no longer subject to further review and comments, the new warrants in exchange as provided above, and such new warrants shall immediately be tradable on the Nasdaq Capital Market and the underlying shares issuable upon exercise of such warrants shall from and after such time be registered and fully tradable in each case to the same extent as the shares of Common Stock sold in the Uplist Transaction (and required current prospectuses shall be provided). Failure of the Borrower to comply with this provision, including the obligations in any of the previous three sentences, shall constitute an Event of Default. If after the Uplist Conversion Warrant is issued to the Holder the Borrower makes a prepayment of all or any portion of the remaining outstanding amount under this Note prior to the Maturity Date, the prepayment shall not be subject to the prepayment premiums set forth in Section 1.9 herein.

Upon the Automatic Conversion, a Holder shall receive pre-funded warrants (the “Note Conversion Pre-Funded Warrants”) in lieu of shares of Common Stock otherwise issuable to the Holder to the extent that the sum of (1) the number of shares of Common Stock beneficially owned by the Holder and its affiliates (other than shares of Common Stock which may be deemed beneficially owned through the ownership of the unconverted portion of the Notes or the unexercised or unconverted portion of any other security of the Borrower subject to a limitation on conversion or exercise analogous to the limitations contained herein) and (2) the number of shares of Common Stock issuable upon the Automatic Conversion with respect to which the determination of this sentence is being made, would result in beneficial ownership by the Holder and its affiliates of more than 4.99% (or 9.99% if elected in writing by the Holder prior to the date of the execution of this Amendment) of the outstanding shares of Common Stock. For purposes of the immediately preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act, and Regulations 13D-G thereunder, provided, that the limit may be waived by the Holder (up to a maximum of 9.99%) upon, at the election of the Holder, not less than 61 days’ prior notice to the Borrower, and the provisions of the conversion limitation shall continue to apply until such 61st day (or such later date, as determined by the Holder, as may be specified in such notice of waiver). The Note Conversion Pre-Funded Warrants shall have a nominal exercise price of $0.000125 per share (subject to adjustment for stock splits and similar transactions occurring after the date of the execution of this Amendment), may be exercised on a cashless basis, shall be exercisable immediately upon issuance, shall contain a customary beneficial ownership limitation provision and shall otherwise be identical to the pre-funded warrants issued in the Uplist PIPE.

ARTICLE IV. MISCELLANEOUS

4.1    Failure or Indulgence Not Waiver. No failure or delay on the part of the Holder in the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other right, power or privileges. All rights and remedies existing hereunder are cumulative to, and not exclusive of, any rights or remedies otherwise available.

4.2    Notices. All notices, demands, requests, consents, approvals, and other communications required or permitted hereunder shall be in writing and, unless otherwise specified herein, shall be (i) personally served, (ii) deposited in the mail, registered or certified, return receipt requested, postage prepaid, (iii) delivered by reputable air courier service with charges prepaid, or (iv) transmitted by hand delivery, electronic mail, or facsimile, addressed as set forth below or to such other address as such party shall have specified most recently by written notice.

If to the Borrower, to:

Framingham, MA 01702

Attn:

If to the Holder:

Attn:

4.3    Amendments. Any modifications, amendments or waivers of the provisions hereof shall be subject to Section 7(e) of the Purchase Agreement. The term “Note” and all reference thereto, as used throughout this instrument, shall mean this instrument (and the other Notes issued pursuant to the Purchase Agreement) as originally executed, or if later amended or supplemented, then as so amended or supplemented.

4.4    Assignability. This Note shall be binding upon the Borrower and its successors and assigns, and shall inure to be the benefit of the Holder and its successors and assigns. Neither the Borrower nor the Holder shall assign this Note or any rights or obligations hereunder without the prior written consent of the other. Notwithstanding the foregoing, the Holder may assign its rights hereunder to any “accredited investor” (as defined in Rule 501(a) of the 1933 Act) in a private transaction from the Holder or to any of its “affiliates”, as that term is defined under the 1934 Act, without the consent of the Borrower. Notwithstanding anything in this Note to the contrary, this Note may be pledged as collateral in connection with a bona fide margin account or other lending arrangement. The Holder and any assignee, by acceptance of this Note, acknowledge and agree that following conversion of a portion of this Note, the unpaid and unconverted principal amount of this Note represented by this Note may be less than the amount stated on the face hereof.

4.5    Cost of Collection. If an Event of Default shall have occurred, the Borrower shall pay the Holder hereof reasonable costs of collection, including reasonable attorneys’ fees.

4.6   Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Note shall be governed by the internal laws of the State of Nevada, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Nevada or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Nevada.

4.7    Certain Amounts. Whenever pursuant to this Note the Borrower is required to pay an amount in excess of the outstanding principal amount (or the portion thereof required to be paid at that time) plus accrued and unpaid interest plus Default Interest on such interest, the Borrower and the Holder agree that the actual damages to the Holder from the receipt of cash payment on this Note may be difficult to determine and the amount to be so paid by the Borrower represents stipulated damages and not a penalty and is intended to compensate the Holder in part for loss of the opportunity to convert this Note and to earn a return from the sale of shares of Common Stock acquired upon conversion of this Note at a price in excess of the price paid for such shares pursuant to this Note. The Borrower and the Holder hereby agree that such amount of stipulated damages is not plainly disproportionate to the possible loss to the Holder from the receipt of a cash payment without the opportunity to convert this Note into shares of Common Stock.

4.8    Purchase Agreement. By its acceptance of this Note, each party agrees to be bound by the applicable terms of the Purchase Agreement.

4.9    Notice of Corporate Events. Except as otherwise provided below, the Holder of this Note shall have no rights as a Holder of Common Stock unless and only to the extent that it converts this Note into Common Stock. The Borrower shall provide the Holder with prior notification of any meeting of the Borrower’s shareholders (and copies of proxy materials and other information sent to shareholders). In the event of any taking by the Borrower of a record of its shareholders for the purpose of determining shareholders who are entitled to receive payment of any dividend or other distribution, any right to subscribe for, purchase or otherwise acquire (including by way of merger, consolidation, reclassification or recapitalization) any share of any class or any other securities or property, or to receive any other right, or for the purpose of determining shareholders who are entitled to vote in connection with any proposed sale, lease or conveyance of all or substantially all of the assets of the Borrower or any proposed liquidation, dissolution or winding up of the Borrower, the Borrower shall mail a notice to the Holder, at least twenty (20) days prior to the record date specified therein (or thirty (30) days prior to the consummation of the transaction or event, whichever is earlier), of the date on which any such record is to be taken for the purpose of such dividend, distribution, right or other event, and a brief statement regarding the amount and character of such dividend, distribution, right or other event to the extent known at such time. The Borrower shall make a public announcement of any event requiring notification to the Holder hereunder substantially simultaneously with the notification to the Holder in accordance with the terms of this Section 4.9 including, but not limited to, name changes, recapitalizations, etc. as soon as possible under law.

4.10    Usury. If it shall be found that any interest or other amount deemed interest due hereunder violates the applicable law governing usury, the applicable provision shall automatically be revised to equal the maximum rate of interest or other amount deemed interest permitted under applicable law. The Borrower covenants (to the extent that it may lawfully do so) that it will not seek to claim or take advantage of any law that would prohibit or forgive the Borrower from paying all or a portion of the principal or interest on this Note.

4.11    Remedies. The Borrower acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder, by vitiating the intent and purpose of the transaction contemplated hereby. Accordingly, the Borrower acknowledges that the remedy at law for a breach of its obligations under this Note will be inadequate and agrees, in the event of a breach or threatened breach by the Borrower of the provisions of this Note, that the Holder shall be entitled, in addition to all other available remedies at law or in equity, and in addition to the penalties assessable herein, to an injunction or injunctions restraining, preventing or curing any breach of this Note and to enforce specifically the terms and provisions thereof, without the necessity of showing economic loss and without any bond or other security being required. No provision of this Note shall alter or impair the obligation of the Borrower, which is absolute and unconditional, to pay the principal of, and interest on, this Note at the time, place, and rate, and in the form, herein prescribed.

4.12    Severability. In the event that any provision of this Note is invalid or unenforceable under any applicable statute or rule of law, then such provision shall be deemed inoperative to the extent that it may conflict therewith and shall be deemed modified to conform with such statute or rule of law. Any provision hereof which may prove invalid or unenforceable under any law shall not affect the validity or enforceability of any other provision hereof.

4.13    Dispute Resolution.

Such investment bank’s or accountant’s determination or calculation shall be binding upon all parties absent demonstrable error. The non-prevailing party shall be responsible for the payment investment bank or the account for their services pursuant to the provisions of this Section 4.13.
