CONVERTIBLE PROMISSORY NOTE

FOR VALUE RECEIVED, NANOFLEX POWER CORPORATION, a Florida corporation (hereinafter called the “Borrower”), hereby promises to pay to the order of POWER UP LENDING GROUP LTD., a Virginia corporation, or registered assigns (the “Holder”) the sum of $63,000.00 together with any interest as set forth herein, on December 15, 2019 (the “Maturity Date”), and to pay interest on the unpaid principal balance hereof at the rate of twelve percent (12%)(the “Interest Rate”) per annum from the date hereof (the “issue Date”) until the same becomes due and payable, whether at maturity or upon acceleration or by prepayment or otherwise. This Note may not be prepaid in whole or in part except as otherwise explicitly set forth herein. Any amount of principal or interest on this Note which is not paid when due shall bear interest at the rate of twenty two percent (22%) per annum from the due date thereof until the same is paid (“Default Interest”). Interest shall commence accruing on the date that the Note is fully paid and shall be computed on the basis of a 365-day year and the actual number of days elapsed. All payments due hereunder (to the extent not converted into common stock, $0.0001 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. Each capitalized term used herein, and not otherwise defined, shall have the meaning ascribed thereto in that certain Securities Purchase Agreement dated the date hereof, pursuant to which this Note was originally issued (the “Purchase Agreement”).

This Note is free from all 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 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 during the period beginning on the date which is one hundred eighty (180) days following the date of this Note 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), 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 (the “Conversion Price”) 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 1.3(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. The beneficial ownership limitations on conversion as set forth in the section may NOT be waived by the Holder. 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 6:00 p.m., New York, New York time on such conversion date (the “Conversion Date”); however, if the Notice of Conversion is sent after 6:00pm, New York, New York time the Conversion Date shall be the next business day. 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, 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 1.4 hereof.

1.2 Conversion Price . The conversion price (the “Conversion Price”) shall equal the Variable Conversion Price (as defined herein) (subject to equitable adjustments by the Borrower relating to the Borrower’s securities or the securities of any subsidiary of the Borrower, combinations, recapitalization, reclassifications, extraordinary distributions and similar events). The “Variable Conversion Price” shall mean 61% multiplied by the Market Price (as defined herein) (representing a discount rate of 39%). “Market Price” means the average of the lowest two (2) Trading Prices (as defined below) for the Common Stock during the fifteen (15) Trading Day period ending on the latest complete Trading Day prior to the Conversion Date. “Trading Price” means, for any security as of any date, the closing bid price on the OTCQB, OTCQX, Pink Sheets electronic quotation system or applicable trading market (the “OTC”) as reported by a reliable reporting service (“Reporting Service”) designated by the Holder (i.e. Bloomberg) or, if the OTC is not the principal trading market for such security, the closing bid price of such security on the principal securities exchange or trading market where such security is listed or traded or, if no closing bid price of such security is available in any of the foregoing manners, the average of the closing bid prices of any market makers for such security that are listed in the “pink sheets”. If the Trading Price cannot be calculated for such security on such date in the manner provided above, the Trading Price shall be the fair market value as mutually determined by the Borrower and the holders of a majority in interest of the Notes being converted for which the calculation of the Trading Price is required in order to determine the Conversion Price of such Notes. “Trading Day” shall mean any day on which the Common Stock is tradable for any period on the OTC, or on the principal securities exchange or other securities market on which the Common Stock is then being traded.

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, The Borrower is required at all times to have authorized and reserved eight times the number of shares that would be issuable upon full conversion of the Note (assuming that the 4.99% limitation set forth in Section 1.1 is not in effect)(based on the respective Conversion Price of the Note (as defined in Section 1.2) in effect from time to time, initially 17,035,659)(the “Reserved Amount”). The Reserved Amount shall be increased (or decreased with the written consent of the Holder) from time to time in accordance with the Borrower’s obligations hereunder. 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 Note. 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 the Reserved Amount it will be considered an Event of Default under Section 3.2 of the Note.

1.4 Method of Conversion .

(a) Mechanics of Conversion. As set forth in Section 1.1 hereof, from time to time, and at any time during the period beginning on the date which is one hundred eighty (180) days following the date of this Note and ending on the later of: (i) the Maturity Date and (ii) the date of payment of the Default Amount, this Note may be converted by the Holder in whole or in part at any time from time to time 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 6:00 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 (upon payment in full of any amounts owed hereunder).

(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.

(c) 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 three (3) 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. 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 hereunder, 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.

(d) 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 set forth herein, the Borrower shall use its 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 Agent Commission (“DWAC”) system.

(e) Failure to Deliver Common Stock Prior to 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 due to action and/or inaction of the Borrower, the Borrower shall pay to the Holder $2,000 per day in cash, for each day beyond the Deadline that the Borrower fails to deliver such Common Stock (the “Fail to Deliver Fee”); provided; however that the Fail to Deliver Fee shall not be due if the failure is a result of a third party (i.e., transfer agent; and not the result of any failure to pay such transfer agent) despite the best efforts of the Borrower to effect delivery of such Common Stock. 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(e) are justified.

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 (such as Rule 144 or a successor rule) (“Rule 144”); or (iii) 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).

Any restrictive legend on certificates representing shares of Common Stock issuable upon conversion of this Note shall be removed and the Borrower shall issue to the Holder a new certificate therefore free of any transfer legend if the Borrower or its transfer agent shall have received an opinion of counsel from Holder’s counsel, in form, substance and scope customary for opinions of counsel in comparable transactions, to the effect that (i) a public sale or transfer of such Common Stock may be made without registration under the Act, which opinion shall be accepted by the Company 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 an exemption from registration. In the event that the Company does not reasonably accept the opinion of counsel provided by the Holder with respect to the transfer of Securities pursuant to an exemption from registration (such as Rule 144), 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 shall be deemed to be an Event of Default (as defined in Article III) pursuant to which the Borrower shall be required to pay to the Holder upon the consummation of and as a condition to such transaction an amount equal to the Default Amount (as defined in Article III). “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 Note, 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, to the extent practicable, ten (10) days prior written notice (but in any event at least five (5) 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, recapitalization, 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 Note. 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.

1.7 Prepayment. Notwithstanding anything to the contrary contained in this Note, at any time during the periods set forth on the table immediately following this paragraph (the “Prepayment Periods”), the Borrower shall have the right, exercisable on not more 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, in accordance with this Section 1.7. Any notice of prepayment hereunder (an “Optional Prepayment Notice”) shall be delivered to the Holder of the Note at its registered addresses 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 more than three (3) Trading Days from the date of the Optional Prepayment Notice. On the date fixed for prepayment (the “Optional Prepayment Date”), the Borrower shall make payment of the Optional Prepayment Amount (as defined below) to Holder, or upon the direction of the Holder as specified by the Holder in a writing to the Borrower (which direction shall to be sent to Borrower by the Holder at least one (1) business day prior to the Optional Prepayment Date). If the Borrower exercises its right to prepay the Note, the Borrower shall make payment to the Holder of an amount in cash equal to the percentage (“Prepayment Percentage”) as set forth in the table immediately following this paragraph opposite the applicable Prepayment Period, 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 to the Optional Prepayment Date plus (y) Default Interest, if any, on the amounts referred to in clauses (w) and (x) plus (z) any amounts owed to the Holder pursuant to Section 1.4 hereof (the “Optional Prepayment Amount”). If the Borrower delivers an Optional Prepayment Notice and fails to pay the Optional 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 this Section 1.7.

After the expiration of one hundred eighty (180) days following the Issue Date, the Borrower shall have no right of prepayment.

ARTICLE II. CERTAIN COVENANTS

2.1 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.

It is an obligation of the Borrower to remain current in its obligations to its transfer agent. It shall be an event of default of this Note, if a conversion of this Note is delayed, hindered or frustrated due to a balance owed by the Borrower to its transfer agent. If at the option of the Holder, the Holder advances any funds to the Borrower’s transfer agent in order to process a conversion, such advanced funds shall be paid by the Borrower to the Holder within forty-eight (48) hours of a demand from the Holder.

3.3 Breach of Covenants. The Borrower breaches any material covenant or other material term or condition contained in this Note and the Purchase Agreement and such breach continues for a period of twenty (20) days after written notice thereof to the Borrower from the Holder.

3.10 Cessation of Operations. Any cessation of operations by Borrower or Borrower admits it is otherwise generally unable to pay its debts as such debts become due, provided, however, that any disclosure of the Borrower’s ability to continue as a “going concern” shall not be an admission that the Borrower cannot pay its debts as they become due.

3.11 Financial Statement Restatement. The restatement of any financial statements filed by the Borrower with the SEC at any time after 180 days after the Issuance Date for any date or period until this Note is no longer outstanding, if the result of such restatement would, by comparison to the un-restated financial statement, have constituted a material adverse effect on the rights of the Holder with respect to this Note or the Purchase Agreement.

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.

12% CONVERTIBLE REDEEMABLE NOTE

DUE FEBRUARY 22, 2020

FOR VALUE RECEIVED, NANOFLEX POWER CORPORATION (the “Company”) promises to pay to the order of ONE44 CAPITAL LLC and its authorized successors and permitted assigns (“Holder”), the aggregate principal face amount of Seventy Thousand Dollars exactly (U.S. $70,000.00) on February 22, 2020 (“ Maturity Date ”) and to pay interest on the principal amount outstanding hereunder at the rate of 12% per annum commencing on February 22, 2019 (“ 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 1249 Broadway, Suite 103, Hewlett, NY 11557, 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) During the first 6 months following the issuance of this Note, the Holder of this Note is entitled, at its option, 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 at fixed price of $0.25 per share. After the 6 monthly anniversary, the Conversion Price shall be equal to 60% of the lowest trading price of the Common Stock as reported on the National Quotations Bureau OTC Marketplace 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 twenty prior trading days including the day upon which a Notice of Conversion is received by the Company or its transfer agent (provided such Notice of Conversion is delivered by fax or other electronic method of communication to the Company or its transfer agent after 4 P.M. Eastern Standard or Daylight Savings Time if the Holder wishes to include the same day closing price). 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 50% instead of 60% while that “Chill” is in effect. 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 Investor).

(b) Interest on any unpaid principal balance of this Note shall be paid at the rate of 12% 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. 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 or assigned with the following penalties/ premiums:

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 of the right to redeem shall be null and void.

(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 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 or ceases to file its 1934 act reports with the SEC;

(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 herein without restrictive legend within 3 business days of its receipt of a Notice of Conversion; or

(1) 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 and 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 conversion notice 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%. Further, if 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 delinquency period as a base price for the conversion. For example, if the lowest closing bid price during the delinquency 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 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 or (ii) accept such opinion from Holder’s counsel.

12. The Company shall issue irrevocable transfer agent instructions reserving 11,666,000 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 transfer agent costs associated with issuing and delivering the share certificates to the Holder, as well as maintaining the Share Reserve. If such amounts are to be paid by the Holder, it may deduct such amounts from the Conversion Price. 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 New York applicable to contracts made and wholly to be performed within the State of New York 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, or the Federal courts within the southern or eastern districts 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.

Exhibit 4.3

certificate of DESIGNATION OF

SERIES A REDEEMABLE PARTICIPATING CONVERTIBLE PREFERRED STOCK

of

Nanoflex power corporation

Pursuant to the provisions of Section 607.0601

of the Florida Business Corporation Act

NanoFlex Power Corporation (the “ Corporation ”), a corporation organized and validly existing under the Florida Business Corporation Act (“ FBCA ”), hereby certifies that the following resolutions have been duly adopted by the Corporation’s Board of Directors by means of a Unanimous Consent of the Board of Directors executed on February 15, 2019, pursuant to authority conferred upon the Board of Directors by the Corporation’s Certificate of Incorporation and the FBCA:

WHEREAS , the Certificate of Incorporation of the Corporation (the “ Certificate ”), authorizes a class of stock designated as Preferred Stock (the “ Preferred Stock ”), comprising 100,000,000 shares, par value $0.0001 per share, provides that such Preferred Stock may be issued from time to time in one or more series, and vests authority in the Board of Directors, within the limitations and restrictions stated in the Certificate, to fix or alter the voting powers, designations, preferences and relative participating, optional or other special rights, rights and terms of redemption, the redemption price or prices and the liquidation preferences of any series of Preferred Stock within the limitations set forth in the Florida Business Corporation Act;

WHEREAS , it is the desire of the Board of Directors to designate one new series of Preferred Stock and to fix the voting powers, designations, preferences and rights, and the qualifications, limitations or restrictions thereof, as provided herein.

NOW, THEREFORE, BE IT RESOLVED , that the Corporation does hereby designate up to 10,000 shares of the authorized but unissued Preferred Stock as Series A Redeemable Participating Convertible Preferred Stock (the “ Series A Preferred ”) and does hereby fix the powers, preferences and relative participating, optional or other special rights and qualifications, limitations or restrictions of the Series A Preferred to be as follows:

SERIES A CONVERTIBLE PREFERRED STOCK

A. Designation . 10,000 shares of the authorized, but undesignated preferred stock, $0.0001 par value per share, of the Corporation are hereby constituted as a series of the preferred stock designated as “Series A Redeemable Participating Convertible Preferred Stock” (“ Series A Preferred ”). The date on which the Corporation initially issues any share of Series A Preferred shall be deemed to be its “ date of issuance ” regardless of the number of times transfer of such share is made on the stock records maintained by or for the Corporation and regardless of the number of certificates which may be issued to evidence such share. The Series A Preferred shall have rights and preferences relative to all other classes and series of the capital stock of the Corporation as set forth herein.

B. Dividends . The holders of Series A Preferred shall be entitled to receive dividends when and as declared by the Board of Directors. No dividends (other than those payable solely in Common Stock) shall be paid on the Common Stock or any class or series of capital stock ranking junior, as to dividends, to the Series A Preferred during any fiscal year of the Corporation until there shall have been paid or declared and set apart during that fiscal year for the holders of the Series A Preferred a dividend in an amount per share equal to (i) the number of shares of Common Stock issuable upon conversion of the Series A Preferred Stock times (ii) the amount per share of the dividend to be paid on the Common Stock.

C. Preference on Liquidation .

1. Upon the occurrence of any liquidation, dissolution or winding up of the Corporation, either voluntary or involuntary (a “ Liquidating Event ”), each holder of Series A Preferred then outstanding shall be entitled to receive, out of the assets of the Corporation available for distribution to its stockholders, before any payment shall be made in respect of the Common Stock, or other series of preferred stock then in existence that is outstanding and junior to the Series A Preferred upon liquidation, an amount per share of Series A Preferred equal to three (3) times the price such holder paid to purchase such Series A Preferred (the “ Purchase Price ”) (as adjusted for any stock combination, stock dividend, stock split, recapitalization or other similar transaction occurring after the first date of issuance of the Series A Preferred), plus, accrued and unpaid dividends (the “ Preferred Liquidation Preference ”). Such Preferred Liquidation Preference shall be secured by a first priority security interest on all of the Corporation’s assets. For purposes of this Subsection C.1, the following events shall be deemed a Liquidating Event: (i) a sale, lease, exchange, exclusive license which has the same effect as a sale of all or substantially all of the Corporation’s assets or other disposition of all or substantially all of the Corporation’s assets in one transaction or a series of related transactions and (ii) a merger, tender offer, reorganization, business combination or other transaction as a result of which (a) holders of the Corporation’s issued and outstanding voting securities immediately before such transaction own or control less than a majority of the voting securities of the continuing or surviving entity immediately after such transaction or (b) any of the Series A Preferred is converted into any other property or security (for the avoidance of doubt, other than (1) conversion of the Series A Preferred into Common Stock as provided herein or (2) in connection with an internal restructuring, reorganization, recapitalization or equity financing of the Corporation approved by holders of the Series A Preferred).

2. Written notice of any such Liquidating Event stating a payment date, the place where such payment shall be made and the amount of each payment in liquidation shall be given by first class mail, postage prepaid, not less than ten (10) days prior to the payment date stated therein, to each holder of record of the Series A Preferred at such holder’s address as shown in the records of the Corporation. If upon the occurrence of a Liquidating Event, the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the holders of the Series A Preferred and all other classes or series of stock ranking on a parity with the Series A Preferred upon liquidation the full amount to which they shall be entitled, the holders of the Series A Preferred shall share ratably with any other such class or series in any distribution of assets according to the amounts that would be payable in respect of the shares held by each of them upon such distribution if all amounts payable on or with respect to said shares were paid in full. Upon the occurrence of a Liquidating Event, in the event the Preferred Liquidation Preference is paid in full, the holders of Series A Preferred shall share ratably with holders of Common Stock in any distribution of any remaining assets of the Corporation.

D. Voting . Except as otherwise expressly provided herein or as required by law, the holders of shares of Series A Preferred shall vote together with the holders of Common Stock as a single class. The holder of each share of Series A Preferred (i) shall be entitled to the number of votes with respect to such share equal to the number of shares of Common Stock into which such share of Series A Preferred could be converted on the record date for the subject vote or written consent (or, if there is no such record date, then on the date that such vote is taken or consent is effective) and (ii) shall be entitled to notice of any stockholders’ meeting in accordance with the Bylaws of the Corporation. Fractional votes shall not be permitted, and any fractional voting rights resulting from the above formula (after aggregating all shares of Common Stock into which shares of Series A Preferred held by each holder could be converted) shall be reduced to the nearest whole number.

E. Conversion Rights .

1. Conversion Price . Each share of Series A Preferred Stock shall be convertible into shares of the Corporation’s common stock, par value $0.0001 per share (the “ Common Stock ”), at a conversion price (the “ Conversion Price ”) equal to $0.10, subject to adjustment as set forth herein. The Conversion Price may not be changed absent written agreement of the Corporation.

2. Right to Convert . Each share of Series A Preferred and all accrued and unpaid dividends thereon shall be convertible at the option of the holder thereof, at any time after the issuance of such share, into fully paid and nonassessable shares of Common Stock of the Corporation. The number of shares of Common Stock into which each share of the Series A Preferred may be converted shall be determined by dividing the sum of the Purchase Price of the Series A being converted and any accrued and unpaid dividends by the Conversion Price.

3. Mechanics of Conversion .

(i) The holder of any shares of Series A Preferred may exercise the conversion rights as to such shares or any part thereof by delivering to the Corporation during regular business hours, at the office of any transfer agent of the Corporation for the Series A Preferred, or at the principal office of the Corporation or at such other place as may be designated by the Corporation, the certificate or certificates for the shares to be converted, duly endorsed for transfer to the Corporation or accompanied by a written instrument or instruments of transfer (if required by it), accompanied by written notice stating that the holder elects to convert all or a number of such shares represented by the certificate or certificates. Such notice shall also state such holder’s name or the names of the nominees in which such holder wishes the certificate or certificates for shares of Common Stock to be issued. Conversion shall be deemed to have been effected on the date when such delivery is made, and such date is referred to herein as the “ Conversion Date .” As promptly as practicable thereafter (but in any event within three (3) business days thereafter), the Corporation shall issue and deliver to such holder, at such office or other place designated by the Corporation, a certificate or certificates for the number of full shares of Common Stock to which such holder is entitled and a check for cash with respect to any fractional interest in a share of Common Stock as provided in Subsection E.3 (ii). The holder shall be deemed to have become a stockholder of record on the applicable Conversion Date. Upon conversion of only a portion of the number of shares of Series A Preferred represented by a certificate surrendered for conversion, the Corporation shall issue and deliver to the holder of the certificate so surrendered for conversion, at the expense of the Corporation, a new certificate representing the number of shares of Series A Preferred not so converted.

(ii) No fractional shares of Common Stock or scrip shall be issued upon conversion of shares of Series A Preferred. If more than one share of Series A Preferred shall be surrendered for conversion at any one time by the same holder, the number of full shares of Common Stock issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of Series A Preferred so surrendered. Instead of any fractional shares of Common Stock that would otherwise be issuable upon conversion of any shares of Series A Preferred, the Corporation shall pay a cash adjustment in respect of such fractional interest equal to the value of such fractional interest based upon the Current Market Price of the Common Stock on the Conversion Date. For purposes of this Subsection E.3(ii), the “ Current Market Price ” means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or quoted on a Trading Market, the closing sale price per share of the Common Stock for such date (or the nearest preceding date) on the primary Trading Market or exchange on which the Common Stock is then listed or quoted; (b) if prices for the Common Stock are then reported in the “Pink Sheets” published by the Pink Sheets, LLC (or a similar organization or agency succeeding to its functions of reporting prices), the most recent sale price per share of the Common Stock so reported; or (c) in all other cases, the fair market value of a share of Common Stock as determined by an independent qualified appraiser selected in good faith and paid for by the Investor. Notwithstanding the foregoing, if there is no reported closing price, last reported sales price, or bid and ask prices, as the case may be, for the day in question, then the Current Market Price shall be determined as of the latest date prior to such day for which such closing price, last reported sales price, or bid and ask prices, as the case may be, are available, unless such securities have not been traded on an exchange or in the over-the-counter market for 30 or more days immediately prior to the day in question, in which case the Current Market Price shall be determined in good faith by, and reflected in a formal resolution of, the Board of Directors of the Corporation. For purposes hereof, “ Trading Market ” means any of the following markets or exchanges on which the Common Stock is listed or quoted for trading on the date in question: the NYSE MKT, the Nasdaq Capital Market, the Nasdaq Global Market, the Nasdaq Global Select Market, the New York Stock Exchange, the OTCQB, the OTCQX or the OTC Pink (or any successors to any of the foregoing).

(iii) The Corporation shall pay any and all issue and other taxes that may be payable in respect of any issue or delivery of shares of Common Stock on conversion of Series A Preferred pursuant hereto. The Corporation shall not, however, be required to pay any tax that may be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock in a name other than that in which the Series A Preferred so converted was registered, and no such issue or delivery shall be made unless and until the person requesting such issue has paid to the Corporation the amount of any such tax or has established, to the satisfaction of the Corporation, that such tax has been paid.

(iv) The Corporation shall use its reasonable best efforts to reserve and keep available, out of its authorized but unissued Common Stock, solely for the purpose of effecting the conversion of Series A Preferred, the full number of shares of Common Stock deliverable upon the conversion of all Series A Preferred from time to time outstanding. The Corporation shall from time to time use its best efforts to obtain necessary director and stockholder approvals, in accordance with the laws of the State of Florida, to increase the authorized amount of its Common Stock if at any time the authorized amount of its Common Stock remaining unissued shall not be sufficient to permit the conversion of all of the shares of Series A Preferred at the time outstanding, and shall take all such actions as are necessary to increase such authorized amount of Common Stock upon obtaining such approvals.

(v) If any shares of Common Stock to be reserved for the purpose of conversion of shares of Series A Preferred require registration or listing with, or approval of, any governmental authority, stock exchange or other regulatory body under any federal or state law or regulation or otherwise, before such shares may be validly issued or delivered upon conversion, the Corporation will in good faith and as expeditiously as possible endeavor to secure such registration, listing or approval, as the case may be.

(vi) Assuming there are a sufficient number of authorized shares of Common Stock available for issuance, all shares of Common Stock that may be issued upon conversion of the shares of Series A Preferred will upon issuance by the Corporation be validly issued, fully paid and nonassessable and free from all taxes, liens and charges with respect to the issuance thereof.

(vii) The Corporation will not, by amendment of the Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, 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 to be observed or performed hereunder by the Corporation, but will at all times in good faith assist in the carrying out of all of the provisions of this Section E and in the taking of all such action as may be necessary or appropriate in order to protect the conversion rights of the holders of the Series A Preferred against impairment.

(viii) Assuming there are a sufficient number of authorized shares of Common Stock available for issuance upon such conversion, if by the third trading day after a Conversion Date the Corporation fails to deliver the required number of shares of Common Stock underlying the Series A Preferred in the manner required pursuant to this Subsection E.3, then the applicable holder of Series A Preferred will have the right to rescind such conversion.

(ix) Assuming there are a sufficient number of authorized shares of Common Stock available for issuance upon such conversion, if by the third (3 ^rd ) trading day after a Conversion Date the Corporation fails to deliver the required number of shares of Common Stock underlying the Series A Preferred in the manner required pursuant to this Subsection E.3, and if after such third (3 ^rd ) trading day and prior to the receipt of such shares of Common Stock, shares of Common Stock are purchased by or for the account of the applicable holder of Series A Preferred (in an open market transaction or otherwise) to deliver in satisfaction of a sale by such holder of the underlying shares of Common Stock which such holder anticipated receiving upon such conversion (a “ Buy-In ”), then the Corporation shall (1) pay in cash to such holder the amount by which (x) such holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the number of underlying shares of Common Stock that the Corporation was required to deliver to such holder in connection with such conversion by (B) the closing price of the Common Stock on the Conversion Date and (2) at the option of such holder, either reinstate the number of shares of Series A Preferred for which such conversion was not honored or deliver to such holder the number of shares of Common Stock that would have been issued had the Corporation timely complied with its conversion and delivery obligations hereunder. Any such holder of Series A Preferred shall provide the Corporation written notice indicating the amounts payable to such holder in respect of the Buy-In.

F. Mandatory Redemption upon Bankruptcy Triggering Event . Notwithstanding anything to the contrary herein, and notwithstanding any conversion that is then required or in process, upon any Bankruptcy Triggering Event, the Corporation shall immediately redeem, in cash, each of the Series A Preferred then outstanding at the Preferred Liquidation Preference, without the requirement for any notice or demand or other action by the holder of Series A Preferred or any other person or entity, provided that such holder may, in its sole discretion, waive such right to receive payment upon a Bankruptcy Triggering Event, in whole or in part, and any such waiver shall not affect any other rights of such holder or any other holder hereunder, including any other rights in respect of such Bankruptcy Triggering Event, any right to conversion, and any right to payment of the Preferred Liquidation Preference. Such mandatory redemption right shall be secured by a first priority security interest on all of the Corporation’s assets. For purposes hereof, “ Bankruptcy Triggering Event ” means, (i) bankruptcy, insolvency, reorganization or liquidation proceedings or other proceedings for the relief of debtors shall be instituted by or against the Corporation and, if instituted against the Corporation by a third party, shall not be dismissed within ninety (90) days of their initiation, (ii) the commencement by the Corporation of a voluntary case or proceeding under any applicable federal, state or foreign bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by it to the entry of a decree, order, judgment or other similar document in respect of the Corporation in an involuntary case or proceeding under any applicable federal, state or foreign bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under any applicable federal, state or foreign law, or the consent by it to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Corporation or of any substantial part of its property, or the making by it of an assignment for the benefit of creditor, or the execution of a composition of debts, or the occurrence of any other similar federal, state or foreign proceeding, or the admission by it in writing or its inability to pay its debts generally as they become due, the taking of corporate action by the Corporation in furtherance of any such action or the taking of any action by any person or entity to commence a Uniform Commercial Code foreclosure sale or any other similar action under federal, state or foreign law or (iii) the entry by a court of (a) a decree, order, judgment or other similar document in respect of the Corporation of a voluntary or involuntary case or proceeding under any applicable federal, state or foreign bankruptcy, insolvency, reorganization or other similar law or (b) a decree, order, judgment or other similar document adjudging the Corporation as bankrupt or insolvent, or approving as properly filed a petition seeking liquidation, reorganization, arrangement, adjustment or composition of or in respect of the Company or any Subsidiary under any applicable federal, state or foreign law or (c) a decree, order, judgment or other similar document appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree, order, judgment or other similar document or any such other decree, order, judgment or other similar document unstayed and in effect for a period of ninety (90) consecutive days.

G. Participation Rights . So long as at least 50% of the Series A Preferred issued remains outstanding, if at any time the Corporation grants, issues or sells any Common Stock or any other securities of the Corporation that would entitle the holder thereof to acquire at any time Common Stock, including, without limitation, any preferred stock, right, option, warrant or other instrument that is at any time convertible into or exercisable or exchangeable for, or otherwise entitles the holder thereof to receive, Common Stock (“ Common Stock Equivalents ”) or rights to purchase stock, warrants or equity securities to any person or entity (the “ Purchase Rights ”), then the holders of Series A Preferred will be entitled to acquire, upon the terms applicable to such Purchase Rights, ratably, the aggregate Purchase Rights which such holder could have acquired if the holder had held the number of shares of Common Stock acquirable upon complete conversion of such holder’s Series A Preferred immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights.

H. Subsequent Equity Sales . If at any time, while the Series A Preferred is outstanding, the Corporation enters into (without the prior written consent of the holders of Series A Preferred), a transaction involving the sale or grant of any option to purchase or sells or grants any right to reprice, or otherwise disposes of or issues (or announces any sale, grant or any option to purchase or other disposition), any Common Stock or Common Stock Equivalents entitling any person or entity to acquire shares of Common Stock at a determinable effective price per share that is lower than the Conversion Price (such lower price, the “ Base Conversion Price ” and such issuances, collectively, a “ Dilutive Issuance ”) (if the holder of the Common Stock or Common Stock Equivalents so issued as part of such transaction shall at any time, whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or otherwise, or due to warrants, options or rights per share which are issued in connection with such issuance, be entitled to receive shares of Common Stock at a determinable effective price per share that is lower than the Conversion Price, such issuance shall be deemed to have occurred for less than the Conversion Price on such date of Dilutive Issuance), then the Conversion Price shall be reduced to equal the Base Conversion Price. Such adjustment shall be made whenever such Common Stock or Common Stock Equivalents are issued and the Base Conversion Price is determinable. Notwithstanding the foregoing, no adjustment will be made under this Section H in respect of an “ Exempt Issuance .” For the purposes hereof, an Exempt Issuance shall consist of any issuance pursuant to (i) existing warrants and options, (ii) employee options approved by the Corporation’s Board of Directors and (iii) strategic business transactions. The Corporation shall notify the holders of Series A Preferred in writing, no later than the trading day following the issuance of any Common Stock or Common Stock Equivalents subject to this Section H, indicating therein the applicable issuance price, or applicable reset price, exchange price, conversion price and other pricing terms (such notice, the “ Dilutive Issuance Notice ”).

I. Amendment; Waiver . Any term of the Series A Preferred may be amended or waived upon the written consent of the Corporation and the holders of a majority-in-interest of all the Series A Preferred then outstanding, voting together as a single class; provided, however, that the right to convert the Series A Preferred may not be altered or waived, without the written consent of the holders of all of the Series A Preferred then outstanding; and provided, further, that no such amendment or waiver may adversely affect the rights of any holder without such holder’s written consent.

J. Action By Holders . Any action or consent to be taken or given by the holders of the Series A Preferred may be given either at a meeting of the holders of the Series A Preferred called and held for such purpose or by written consent.

IN WITNESS WHEREOF, NanoFlex Power Corporation has caused this Certificate to be signed by Dean L. Ledger, its Chief Executive Officer, this 15 day of February 2019.
