d. Information. The Buyer and its advisors, if any, have been, and for so long as the Note remains outstanding will continue to be, furnished with all materials relating to the business, finances and operations of the Company and materials relating to the offer and sale of the Securities which have been requested by the Buyer or its advisors. The Buyer and its advisors, if any, have been, and for so long as the Note remains outstanding will continue to be, afforded the opportunity to ask questions of the Company. Notwithstanding the foregoing, the Company has not disclosed to the Buyer any material nonpublic information and will not disclose such information unless such information is disclosed to the public prior to or promptly following such disclosure to the Buyer. Neither such inquiries nor any other due diligence investigation conducted by Buyer or any of its advisors or representatives shall modify, amend or affect Buyer’s right to rely on the Company’s representations and warranties contained in Section 3 below.

The Buyer is not aware of any facts that may constitute a breach of any of the Company’s representations and warranties made herein.

f. Transfer or Re-sale. The Buyer understands that (i) the sale or re-sale of the Securities has not been and is not being registered under the 1933 Act or any applicable state securities laws, and the Securities may not be transferred unless (a) the Securities are sold pursuant to an effective registration statement under the 1933 Act, (b) the Buyer shall have delivered to the Company, at the cost of the Buyer, an opinion of counsel that shall be in form, substance and scope customary for opinions of counsel in comparable transactions to the effect that the Securities to be sold or transferred may be sold or transferred pursuant to an exemption from such registration, which opinion shall be accepted by the Company, (c) the Securities are sold or transferred to an “affiliate” (as defined in Rule 144 promulgated under the 1933 Act (or a successor rule) (“Rule 144”) of the Buyer who agrees to sell or otherwise transfer the Securities only in accordance with this Section 2(f) and who is an Accredited Investor, (d) the Securities are sold pursuant to Rule 144, or (e) the Securities are sold pursuant to Regulation S under the 1933 Act (or a successor rule) (“Regulation S”), and the Buyer shall have delivered to the Company, at the cost of the Buyer, an opinion of counsel that shall be in form, substance and scope customary for opinions of counsel in corporate transactions, which opinion shall be accepted by the Company; (ii) any sale of such Securities made in reliance on Rule 144 may be made only in accordance with the terms of said Rule and further, if said Rule is not applicable, any re-sale of such Securities under circumstances in which the seller (or the person through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the 1933 Act) may require compliance with some other exemption under the 1933 Act or the rules and regulations of the SEC thereunder; and (iii) neither the Company nor any other person is under any obligation to register such Securities under the 1933 Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder (in each case). Notwithstanding the foregoing or anything else contained herein to the contrary, the Securities may be pledged as collateral in connection with a bona fide margin account or other lending arrangement.

g. Legends. The Buyer understands that the Note and, until such time as the Conversion Shares have been registered under the 1933 Act or may be sold pursuant to Rule 144 or Regulation S without any restriction as to the number of securities as of a particular date that can then be immediately sold, the Conversion Shares, may bear a restrictive legend in substantially the following form (and a stop-transfer order may be placed against transfer of the certificates for such Securities):

“NEITHER THE ISSUANCE AND SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE EXERCISABLE HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF COUNSEL (WHICH COUNSEL SHALL BE SELECTED BY THE HOLDER), IN A GENERALLY ACCEPTABLE FORM, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT. NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.”

The legend set forth above shall be removed and the Company shall issue a certificate without such legend to the holder of any Security upon which it is stamped, if, unless otherwise required by applicable state securities laws, (a) such Security is registered for sale under an effective registration statement filed under the 1933 Act or otherwise may be sold pursuant to Rule 144 or Regulation S without any restriction as to the number of securities as of a particular date that can then be immediately sold, or (b) such holder provides the Company with 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 Security may be made without registration under the 1933 Act, which opinion shall be accepted by the Company so that the sale or transfer is effected. The Buyer agrees to sell all Securities, including those represented by a certificate(s) from which the legend has been removed, in compliance with applicable prospectus delivery requirements, if any. In the event that the Company does not accept the opinion of counsel provided by the Buyer with respect to the transfer of Securities pursuant to an exemption from registration, such as Rule 144 or Regulation S, within 3 business days, it will be considered an Event of Default under the Note.

h. Authorization; Enforcement. This Agreement has been duly and validly authorized. This Agreement has been duly executed and delivered on behalf of the Buyer, and this Agreement constitutes a valid and binding agreement of the Buyer enforceable in accordance with its terms.

i. Residency. The Buyer is a resident of the jurisdiction set forth immediately below the Buyer’s name on the signature pages hereto.

3. Representations and Warranties of the Company. The Company represents and warrants to the Buyer that:

a. Organization and Qualification. The Company and each of its subsidiaries, if any, is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction in which it is incorporated, with full power and authority (corporate and other) to own, lease, use and operate its properties and to carry on its business as and where now owned, leased, used, operated and conducted.

b. Authorization; Enforcement. (i) The Company has all requisite corporate power and authority to enter into and perform this Agreement, the Note and to consummate the transactions contemplated hereby and thereby and to issue the Securities, in accordance with the terms hereof and thereof, (ii) the execution and delivery of this Agreement, the Note by the Company and the consummation by it of the transactions contemplated hereby and thereby (including without limitation, the issuance of the Note and the issuance and reservation for issuance of the Conversion Shares issuable upon conversion or exercise thereof) have been duly authorized by the Company’s Board of Directors and no further consent or authorization of the Company, its Board of Directors, or its shareholders is required, (iii) this Agreement has been duly executed and delivered by the Company by its authorized representative, and such authorized representative is the true and official representative with authority to sign this Agreement and the other documents executed in connection herewith and bind the Company accordingly, and (iv) this Agreement constitutes, and upon execution and delivery by the Company of the Note, each of such instruments will constitute, a legal, valid and binding obligation of the Company enforceable against the Company in accordance with its terms.

c. Issuance of Shares. The Conversion Shares are duly authorized and reserved for issuance and, upon conversion of the Note in accordance with its respective terms, will be validly issued, fully paid and non-assessable, and 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 Company and will not impose personal liability upon the holder thereof.

d. Acknowledgment of Dilution. The Company understands and acknowledges the potentially dilutive effect to the Common Stock upon the issuance of the Conversion Shares upon conversion of the Note. The Company further acknowledges that its obligation to issue Conversion Shares upon conversion of the Note in accordance with this Agreement, the Note is absolute and unconditional regardless of the dilutive effect that such issuance may have on the ownership interests of other shareholders of the Company.

e. No Conflicts. The execution, delivery and performance of this Agreement, the Note by the Company and the consummation by the Company of the transactions contemplated hereby and thereby (including, without limitation, the issuance and reservation for issuance of the Conversion Shares) will not (i) conflict with or result in a violation of any provision of the Certificate of Incorporation or By-laws, or (ii) violate or conflict with, or result in a breach of any provision of, or constitute a default (or an event which with notice or lapse of time or both could become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture, patent, patent license or instrument to which the Company or any of its Subsidiaries is a party, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state securities laws and regulations and regulations of any self-regulatory organizations to which the Company or its securities are subject) applicable to the Company or any of its Subsidiaries or by which any property or asset of the Company or any of its Subsidiaries is bound or affected (except for such conflicts, defaults, terminations, amendments, accelerations, cancellations and violations as would not, individually or in the aggregate, have a Material Adverse Effect). All consents, authorizations, orders, filings and registrations which the Company is required to obtain pursuant to the preceding sentence have been obtained or effected on or prior to the date hereof. The Company is not in violation of the listing requirements of the OTC Markets Exchange (the “OTC MARKETS”) and does not reasonably anticipate that the Common Stock will be delisted by the OTC MARKETS in the foreseeable future, nor are the Company’s securities “chilled” by FINRA. The Company and its Subsidiaries are unaware of any facts or circumstances which might give rise to any of the foregoing.

f. Absence of Litigation. Except as disclosed in the Company’s public filings, there is no action, suit, claim, proceeding, inquiry or investigation before or by any court, public board, government agency, self-regulatory organization or body pending or, to the knowledge of the Company or any of its subsidiaries, threatened against or affecting the Company or any of its subsidiaries, or their officers or directors in their capacity as such, that could have a material adverse effect. Schedule 3(f) contains a complete list and summary description of any pending or, to the knowledge of the Company, threatened proceeding against or affecting the Company or any of its subsidiaries, without regard to whether it would have a material adverse effect. The Company and its subsidiaries are unaware of any facts or circumstances which might give rise to any of the foregoing.

g. Acknowledgment Regarding Buyer’ Purchase of Securities. The Company acknowledges and agrees that the Buyer is acting solely in the capacity of arm’s length purchasers with respect to this Agreement and the transactions contemplated hereby. The Company further acknowledges that the Buyer is not acting as a financial advisor or fiduciary of the Company (or in any similar capacity) with respect to this Agreement and the transactions contemplated hereby and any statement made by the Buyer or any of its respective representatives or agents in connection with this Agreement and the transactions contemplated hereby is not advice or a recommendation and is merely incidental to the Buyer’ purchase of the Securities. The Company further represents to the Buyer that the Company’s decision to enter into this Agreement has been based solely on the independent evaluation of the Company and its representatives.

h. No Integrated Offering. Neither the Company, nor any of its affiliates, nor any person acting on its or their behalf, has directly or indirectly made any offers or sales in any security or solicited any offers to buy any security under circumstances that would require registration under the 1933 Act of the issuance of the Securities to the Buyer. The issuance of the Securities to the Buyer will not be integrated with any other issuance of the Company’s securities (past, current or future) for purposes of any shareholder approval provisions applicable to the Company or its securities.

i. Title to Property. The Company and its subsidiaries have good and marketable title in fee simple to all real property and good and marketable title to all personal property owned by them which is material to the business of the Company and its subsidiaries, in each case free and clear of all liens, encumbrances and defects except such as are described in Schedule 3(i) or such as would not have a material adverse effect. Any real property and facilities held under lease by the Company and its subsidiaries are held by them under valid, subsisting and enforceable leases with such exceptions as would not have a material adverse effect.

j. Bad Actor. No officer or director of the Company would be disqualified under Rule 506(d) of the Securities Act as amended on the basis of being a “bad actor” as that term is established in the September 19, 2013 Small Entity Compliance Guide published by the Securities and Exchange Commission.

At the Closing, the Company shall reimburse Buyer for expenses incurred by them in connection with the negotiation, preparation, execution, delivery and performance of this Agreement and the other agreements to be executed in connection herewith (“Documents”), including, without limitation, reasonable attorneys’ and consultants’ fees and expenses, transfer agent fees, fees for stock quotation services, fees relating to any amendments or modifications of the Documents or any consents or waivers of provisions in the Documents, fees for the preparation of opinions of counsel, escrow fees, and costs of restructuring the transactions contemplated by the Documents.

b. Listing. The Company shall promptly secure the listing of the Conversion Shares upon each national securities exchange or automated quotation system, if any, upon which shares of Common Stock are then listed (subject to official notice of issuance) and, so long as the Buyer owns any of the Securities, shall maintain, so long as any other shares of Common Stock shall be so listed, such listing of all Conversion Shares from time to time issuable upon conversion of the Note.

c. Corporate Existence. So long as the Buyer beneficially owns any Note, the Company shall maintain its corporate existence and shall not sell all or substantially all of the Company’s assets, except in the event of a merger or consolidation or sale of all or substantially all of the Company’s assets, where the surviving or successor entity in such transaction (i) assumes the Company’s obligations hereunder and under the agreements and instruments entered into in connection herewith and (ii) is a publicly traded corporation whose Common Stock is listed for trading on the OTC MARKETS, Nasdaq, Nasdaq SmallCap or NYSE.

d. No Integration.

e. Funding Lockup. For a period of 45 days following the Closing Date of the Note, the Company shall not issue or consummate the sale of any variable equity securities, including those securities which have the potential to become variable rate equity securities. However the Company may consummate the sale of convertible equity securities in an amount not to exceed $100,000 during this period of time.

f. Breach of Covenants. If the Company breaches any of the covenants set forth in this Section 4, and in addition to any other remedies available to the Buyer pursuant to this Agreement, it will be considered an event of default under the Note.

BRAIN SCIENTIFIC, INC.

8% CONVERTIBLE REDEEMABLE NOTE

DUE September 1, 2021

FOR VALUE RECEIVED, Brain Scientific, Inc. (the “Company”) promises to pay to the order of DIAMOND INVESTMENT GROUP II LLC and its authorized successors and permitted assigns (“Holder”), the aggregate principal face amount of One Hundred Fifty Seven Thousand Five Hundred Dollars (U.S. $157,500.00) on September 1, 2021 (“Maturity Date”) and to pay interest on the principal amount outstanding hereunder at the rate of 8% per annum commencing on September 1, 2020 (“Issuance Date”). The interest will be paid to the Holder in whose name this Note is registered on the records of the Company regarding registration and transfers of this Note. The principal of, and interest on, this Note are payable at 3495 Lakeside Drive, Suite 1279, Reno, NV 89509, initially, and if changed, last appearing on the records of the Company as designated in writing by the Holder hereof from time to time. The Company will pay each interest payment and the outstanding principal due upon this Note before or on the Maturity Date, less any amounts required by law to be deducted or withheld, to the Holder of this Note by check or wire transfer addressed to such Holder at the last address appearing on the records of the Company. The forwarding of such check or wire transfer shall constitute a payment of outstanding principal hereunder and shall satisfy and discharge the liability for principal on this Note to the extent of the sum represented by such check or wire transfer. Interest shall be payable in Common Stock (as defined below) pursuant to paragraph 4(b) herein.

This Note is subject to the following additional provisions:

1. This Note is exchangeable for an equal aggregate principal amount of Notes of different authorized denominations, as requested by the Holder surrendering the same. No service charge will be made for such registration or transfer or exchange, except that Holder shall pay any tax or other governmental charges payable in connection therewith.

2. The Company shall be entitled to withhold from all payments any amounts required to be withheld under applicable laws.

3. This Note may be transferred or exchanged only in compliance with the Securities Act of 1933, as amended (“Act”) and applicable state securities laws. Any attempted transfer to a non-qualifying party shall be treated by the Company as void. Prior to due presentment for transfer of this Note, the Company and any agent of the Company may treat the person in whose name this Note is duly registered on the Company’s records as the owner hereof for all other purposes, whether or not this Note be overdue, and neither the Company nor any such agent shall be affected or bound by notice to the contrary. Any Holder of this Note electing to exercise the right of conversion set forth in Section 4(a) hereof, in addition to the requirements set forth in Section 4(a), and any prospective transferee of this Note, also is required to give the Company written confirmation that this Note is being converted (“Notice of Conversion”) in the form annexed hereto as Exhibit A. The date of receipt (including receipt by telecopy) of such Notice of Conversion shall be the Conversion Date.

4. (a) The Holder of this Note is entitled, at its option, at any time, to convert all or any amount of the principal face amount of this Note then outstanding into shares of the Company’s common stock (the “Common Stock”) at a price (“Conversion Price”) for each share of Common Stock equal to 60% of the lowest closing bid price for the Common Stock (the “Closing Bid Price”) as reported on the National Quotations Bureau OTC exchange which the Company’s shares are traded or any exchange upon which the Common Stock may be traded in the future (“Exchange”), for the fifteen prior trading day period including the day upon which a Notice of Conversion is received by the Company (provided such Notice of Conversion is delivered by fax or other electronic method of communication to the Company after 4 P.M. Eastern Standard or Daylight Savings Time if the Holder wishes to include the same day Closing Bid Price). Notwithstanding the foregoing, in no event shall a Closing Bid Price be used for purposes of determination of the Conversion Price if and to the extent that such Closing Bid Price results from any materially and statistically abnormal or irregular trading activity of Common Stock immediately prior to the closing which would affect the Closing Bid Price. By way of example, if the Common Stock, immediately prior to the closing on a particular day, had an offer of $1.00 per share and a bid of $0.80 per share and the closing bid was $0.20 per share for a nominal number of shares. Holder hereby covenants and agrees that in no event shall Holder take any action, directly or indirectly, or cause any third party to take any action, directly or indirectly, to cause the Closing Bid Price of Common Stock to decrease for purposes of taking advantage of a lower Conversion Price (a “Prohibited Action”). For purposes hereof, a Prohibited Action shall include, but not be limited to, any rigging quotes, prices, or trades of Common Stock, short selling of Common Stock, spreading false or misleading information about the Company, or any other actions which constitute a deliberate attempt to lower the Closing Bid Price of Common Stock, provided, however, that the Holder’s own selling of the Common Stock shall not in any way be deemed a Prohibited Action. In the event that a Closing Bid Price is effected as a result of any Prohibited Action taken by Holder or any third party directed by the Holder, Holder shall not be permitted to use such Closing Bid Price for purposes of calculating the Conversion Price pursuant to this Section 4(a). If the shares have not been delivered within 3 business days, the Notice of Conversion may be rescinded. Such conversion shall be effectuated by the Company delivering the shares of Common Stock to the Holder within 3 business days of receipt by the Company of the Notice of Conversion. Accrued, but unpaid interest shall be subject to conversion. No fractional shares or scrip representing fractions of shares will be issued on conversion, but the number of shares issuable shall be rounded to the nearest whole share. To the extent the Conversion Price of the Company’s Common Stock closes below the par value per share, the Company will take all steps necessary to solicit the consent of the stockholders to reduce the par value to the lowest value possible under law. The Company agrees to honor all conversions submitted pending this increase. In the event the Company experiences a DTC “Chill” on its shares, the conversion price shall be decreased to 55% instead of 60% while that “Chill” is in effect. If the Company has a closing price of less than $0.01 per share, then the Conversion Price shall be decreased by an additional 5% (resulting in a conversion price discount increase of 5% from 40% to 45%). In no event shall the Holder be allowed to effect a conversion if such conversion, along with all other shares of Company Common Stock beneficially owned by the Holder and its affiliates would exceed 4.99% of the outstanding shares of the Common Stock of the Company (which may be increased up to 9.9% upon 60 days’ prior written notice by the Holder). The conversion discount, look back period and other terms will be adjusted on a ratchet basis if the Company offers subsequent to the date hereof a more favorable conversion discount, interest rate, (whether through a straight discount or in combination with an original issue discount), look back period or other more favorable term to another party for any financings while this Note is in effect; provided, however, that no such adjustment shall be made with respect to (i) any financing that results in net proceeds to the Company of $500,000 or greater in a single closing, or (ii) any modifications or amendments to the Company’s debentures or convertible promissory notes which are outstanding as of the Issuance Date.

(b) Interest on any unpaid principal balance of this Note shall be paid at the rate of 8% per annum. Interest shall be paid by the Company in Common Stock (“Interest Shares”). Holder may, at any time, send in a Notice of Conversion to the Company for Interest Shares based on the formula provided in Section 4(a) above, if applicable. The dollar amount converted into Interest Shares shall be all or a portion of the accrued interest calculated on the unpaid principal balance of this Note to the date of such notice.

(c) The Notes may be prepaid with the following penalties:

This Note may not be prepaid after the 180^th day. Such redemption must be closed and funded within 3 days of giving notice of redemption or the right to redeem shall be null and void. Any partial prepayments will be made in accordance with the formula set forth in the chart above with respect to principal, premium and interest.

(d) Upon (i) a transfer of all or substantially all of the assets of the Company to any person in a single transaction or series of related transactions, (ii) a reclassification, capital reorganization or other change or exchange of outstanding shares of the Common Stock, other than a forward or reverse stock split or stock dividend, or (iii) any consolidation or merger of the Company with or into another person or entity in which the Company is not the surviving entity (other than a merger which is effected solely to change the jurisdiction of incorporation of the Company and results in a reclassification, conversion or exchange of outstanding shares of Common Stock solely into shares of Common Stock) (each of items (i), (ii) and (iii) being referred to as a “Sale Event”), then, in each case, the Company shall, upon request of the Holder, redeem this Note in cash for 150% of the principal amount, plus accrued but unpaid interest through the date of redemption, or at the election of the Holder, such Holder may convert the unpaid principal amount of this Note (together with the amount of accrued but unpaid interest) into shares of Common Stock immediately prior to such Sale Event at the Conversion Price.

(e) In case of any Sale Event (not to include a sale of all or substantially all of the Company’s assets) in connection with which this Note is not redeemed or converted, the Company shall cause effective provision to be made so that the Holder of this Note shall have the right thereafter, by converting this Note, to purchase or convert this Note into the kind and number of shares of stock or other securities or property (including cash) receivable upon such reclassification, capital reorganization or other change, consolidation or merger by a holder of the number of shares of Common Stock that could have been purchased upon exercise of the Note and at the same Conversion Price, as defined in this Note, immediately prior to such Sale Event. The foregoing provisions shall similarly apply to successive Sale Events. If the consideration received by the holders of Common Stock is other than cash, the value shall be as determined by the Board of Directors of the Company or successor person or entity acting in good faith.

5. No provision of this Note shall alter or impair the obligation of the Company, 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.

6. The Company hereby expressly waives demand and presentment for payment, notice of non-payment, protest, notice of protest, notice of dishonor, notice of acceleration or intent to accelerate, and diligence in taking any action to collect amounts called for hereunder and shall be directly and primarily liable for the payment of all sums owing and to be owing hereto.

7. The Company agrees to pay all costs and expenses, including reasonable attorneys’ fees and expenses, which may be incurred by the Holder in collecting any amount due under this Note.

8. If one or more of the following described “Events of Default” shall occur:

(a) The Company shall default in the payment of principal or interest on this Note or any other note issued to the Holder by the Company; or

(b) Any of the representations or warranties made by the Company herein or in any certificate or financial or other written statements heretofore or hereafter furnished by or on behalf of the Company in connection with the execution and delivery of this Note, or the Securities Purchase Agreement under which this note was issued (the “Securities Purchase Agreement”) shall be false or misleading in any respect; or

(c) The Company shall fail to perform or observe, in any respect, any covenant, term, provision, condition, agreement or obligation of the Company under this Note or any other note issued to the Holder; or

(d) The Company shall (1) become insolvent; (2) admit in writing its inability to pay its debts generally as they mature; (3) make an assignment for the benefit of creditors or commence proceedings for its dissolution; (4) apply for or consent to the appointment of a trustee, liquidator or receiver for its or for a substantial part of its property or business; (5) file a petition for bankruptcy relief, consent to the filing of such petition or have filed against it an involuntary petition for bankruptcy relief, all under federal or state laws as applicable; or

(e) A trustee, liquidator or receiver shall be appointed for the Company or for a substantial part of its property or business without its consent and shall not be discharged within sixty (60) days after such appointment; or

(f) Any governmental agency or any court of competent jurisdiction at the instance of any governmental agency shall assume custody or control of the whole or any substantial portion of the properties or assets of the Company; or

(g) One or more money judgments, writs or warrants of attachment, or similar process, in excess of fifty thousand dollars ($50,000) in the aggregate, shall be entered or filed against the Company or any of its properties or other assets and shall remain unpaid, unvacated, unbonded or unstayed for a period of fifteen (15) days or in any event later than five (5) days prior to the date of any proposed sale thereunder; or

(h) The Company shall have defaulted on or breached any term of any other note of similar debt instrument into which the Company has entered and failed to cure such default within the appropriate grace period; or

(i) The Company shall have its Common Stock delisted from an exchange (including the OTC Market exchange) or, if the Common Stock trades on an exchange, then trading in the Common Stock shall be suspended for more than 10 consecutive days;

(j) If a majority of the members of the Board of Directors of the Company on the date hereof are no longer serving as members of the Board;

(k) The Company shall not deliver to the Holder the Common Stock pursuant to paragraph 4(a) herein without restrictive legend within 3 business days of its receipt of a Notice of Conversion (subject to Section 2(g) of the Securities Purchase Agreement); or

(l) The Company shall not replenish the reserve set forth in Section 12, within 3 business days of the request of the Holder.

(m) The Company shall not be “current” in its filings with the Securities and Exchange Commission; or

(n) The Company shall lose the “bid” price for its stock in a market (including the OTC marketplace or other exchange).

Then, or at any time thereafter, unless cured within 5 days, and in each and every such case, unless such Event of Default shall have been waived in writing by the Holder (which waiver shall not be deemed to be a waiver of any subsequent default) at the option of the Holder and in the Holder’s sole discretion, the Holder may consider this Note immediately due and payable, without presentment, demand, protest or (further) notice of any kind (other than notice of acceleration), all of which are hereby expressly waived, anything herein or in any note or other instruments contained to the contrary notwithstanding, and the Holder may immediately, and without expiration of any period of grace, enforce any and all of the Holder’s rights and remedies provided herein or any other rights or remedies afforded by law. Upon an Event of Default, interest shall accrue at a default interest rate of 24% per annum or, if such rate is usurious or not permitted by current law, then at the highest rate of interest permitted by law. In the event of a breach of Section 8(k) the penalty shall be $250 per day the shares are not issued beginning on the 4^th day after the Notice of Conversion was delivered to the Company. This penalty shall increase to $500 per day beginning on the 10^th day. The penalty for a breach of Section 8(n) shall be an increase of the outstanding principal amounts by 20%. In the event of a breach of Section 8(l) occurs beginning on the 160^th daily anniversary of the Note, or a breach of Section 8(m) occurs or is continuing after the 6 month anniversary of the Note, then the Holder shall be entitled to use the lowest closing bid price during the breach period as a base price for the conversion. For example, if the lowest closing bid price during the breach period is $0.01 per share and the conversion discount is 50% the Holder may elect to convert future conversions at $0.005 per share.

If the Holder shall commence an action or proceeding to enforce any provisions of this Note, including, without limitation, engaging an attorney, then if the Holder prevails in such action, the Holder shall be reimbursed by the Company for its attorneys’ fees and other costs and expenses incurred in the investigation, preparation and prosecution of such action or proceeding.

Make-Whole for Failure to Deliver Loss. At the Holder’s election, if the Company fails for any reason to deliver to the Holder the conversion shares by the 3rd business day following the delivery of a Notice of Conversion to the Company and if the Holder incurs a Failure to Deliver Loss, then at any time the Holder may provide the Company written notice indicating the amounts payable to the Holder in respect of the Failure to Deliver Loss and the Company must make the Holder whole as follows:

Failure to Deliver Loss = [(Highest VWAP price for the 30 trading days on or after the day of exercise) x (Number of conversion shares)]

The Company must pay the Failure to Deliver Loss by cash payment, and any such cash payment must be made by the third business day from the time of the Holder’s written notice to the Company.

9. In case any provision of this Note is held by a court of competent jurisdiction to be excessive in scope or otherwise invalid or unenforceable, such provision shall be adjusted rather than voided, if possible, so that it is enforceable to the maximum extent possible, and the validity and enforceability of the remaining provisions of this Note will not in any way be affected or impaired thereby.

10. Neither this Note nor any term hereof may be amended, waived, discharged or terminated other than by a written instrument signed by the Company and the Holder.

11. The Company represents that it is not a “shell” issuer and has never been a “shell” issuer or that if it previously has been a “shell” issuer that at least 12 months have passed since the Company has reported form 10 type information indicating it is no longer a “shell” issuer. Further, the Company will instruct its counsel to either (i) write a 144 opinion to allow for salability of the conversion shares (provided Holder provides customary certifications for such counsel to rely upon to issue its opinion) or (ii) accept such opinion from Holder’s counsel, in each case subject to Section 2(g) of the Securities Purchase Agreement.

12. The Company shall issue irrevocable transfer agent instructions reserving 840,00 shares of its Common Stock for conversions under this Note (the “Share Reserve”). Upon full conversion of this Note, any shares remaining in the Share Reserve shall be cancelled. The Company shall pay all costs associated with issuing and delivering the shares. If such amounts are to be paid by the Holder, it may deduct such amounts from the principal amount being converted. The company should at all times reserve a minimum of four times the amount of shares required if the note would be fully converted.  The Holder may reasonably request increases from time to time to reserve such amounts. The Company will instruct its transfer agent to provide the outstanding share information to the Holder in connection with its conversions.

13. The Company will give the Holder direct notice of any corporate actions, including but not limited to name changes, stock splits, recapitalizations etc. This notice shall be given to the Holder as soon as possible under law.

14. 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 Company 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 Company from paying all or a portion of the principal or interest on this Note.

15. This Note shall be governed by and construed in accordance with the laws of Nevada applicable to contracts made and wholly to be performed within the State of Nevada and shall be binding upon the successors and assigns of each party hereto. The Holder and the Company hereby mutually waive trial by jury and consent to exclusive jurisdiction and venue in the courts of the State of New York or in the Federal courts sitting in the county or city of New York. This Agreement may be executed in counterparts, and the facsimile transmission of an executed counterpart to this Agreement shall be effective as an original.

IN WITNESS WHEREOF, the Company has caused this Note to be duly executed by an officer thereunto duly authorized.
