accordance with GAAP applied on a consistent basis during the periods involved, except as may be otherwise specified in such financial statements or the notes thereto and except that unaudited financial statements may not contain all footnotes
required by GAAP, and fairly present in all material respects the financial position of the Company and its consolidated subsidiaries taken as a whole as of and for the dates thereof and the results of operations and cash flows for the periods then
ended, subject, in the case of unaudited statements, to normal, immaterial year-end audit adjustments. 
 (j) Material
Changes. Since the date of the latest audited financial statements included within the SEC Reports, except as specifically disclosed in a subsequent SEC Report filed prior to the date hereof, (i) there have been no events, occurrences or
developments that have had or would reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect, (ii) the Company has not incurred any material liabilities (contingent or otherwise) other than

Transaction Documents or the sale of the Debentures. Neither the Company nor any Subsidiary, nor to the Company’s Knowledge any director or officer thereof, is or has been the subject of any Action involving a claim of violation of or liability
under federal or state securities laws or a claim of breach of fiduciary duty. There has not been, and to the Company’s Knowledge there is not pending or contemplated, any investigation by the Commission involving the Company or any current or
former director or officer of the Company. The Commission has not issued any stop order or other order suspending the effectiveness of any registration statement filed by the Company or any of its Subsidiaries under the Exchange Act or the
Securities Act. 
 (l) Employment Matters. None of the Company’s or any Subsidiary’s employees is a member of a
union that relates to such employee’s relationship with the Company, and neither the Company nor any of its Subsidiaries is a party to a collective bargaining agreement, and the Company and each Subsidiary believes that its relationship with
its employees is good. No executive officer of the Company (as defined in Rule 501(f) of the Securities Act) has notified the Company or any such Subsidiary that such officer intends to leave the Company or any such Subsidiary or otherwise terminate
such officer’s employment with the Company or any such Subsidiary. To the Company’s Knowledge, no executive officer, to the Company’s Knowledge, is, or is now expected to be, in violation of any term of any material term of any
employment contract, confidentiality, disclosure or proprietary information agreement or non-competition agreement, or any other contract or agreement or any restrictive covenant in favor of a third party, and to the Company’s Knowledge, the
continued employment of each such executive officer does not subject the Company or any Subsidiary to any liability with respect to any of the foregoing matters.

 (m) Regulatory Permits. The Company and each of its Subsidiaries possess all
certificates, authorizations and permits issued by the appropriate federal, state, local or foreign regulatory authorities necessary to conduct its respective business as currently conducted and as described in the SEC Reports, except where the

has received any notice of Proceedings relating to the revocation or modification of any such Material Permits. 
 (n) Title
to Assets. The Company and its Subsidiaries have good and marketable title in fee simple to all real property owned by them. The Company and its Subsidiaries have good and marketable title to all tangible personal property owned by them that is
material to the business of the Company and its Subsidiaries, taken as whole, in each case free and clear of all Liens except such as do not materially affect the value of such property and do not interfere with the use made and proposed to be made
of such property by the Company and any of its Subsidiaries. Any real property and facilities held under lease by the Company and any of its Subsidiaries are held by them under valid, subsisting and enforceable leases with such exceptions as are not
material and do not interfere with the use made and proposed to be made of such property and buildings by the Company and its Subsidiaries. 
 (o) Patents and Trademarks. To the Company’s Knowledge, the Company and the Subsidiaries own, possess, license or have other rights to use, all patents, patent applications, trade and service
marks, trade and service mark applications and registrations, trade names, trade secrets, inventions, copyrights, licenses, technology, know-how and other intellectual property rights and similar rights described in the SEC Reports as necessary or
material for use in connection with their respective businesses and which the failure to so have would have or reasonably be expected to result in a Material Adverse Effect (collectively, the “ Intellectual Property Rights”).
Neither the Company nor any Subsidiary has received a notice (written or otherwise) that any of the Intellectual Property Rights used by the Company or any Subsidiary violates or infringes upon the rights of any Person. There is no pending or, to
the Company’s Knowledge, threatened action, suit, proceeding or claim by any Person that the Company’s business as now conducted infringes or otherwise violates any patent, trademark, copyright, trade secret or other proprietary rights of
another. To the Company’s Knowledge, there is no existing infringement by another Person of any of the Intellectual Property Rights that would have or would reasonably be expected to have a Material Adverse Effect. The Company and its
Subsidiaries have taken reasonable security measures to protect the secrecy, confidentiality and value of all of their Intellectual Property Rights, except where failure to do so could not, individually or in the aggregate, reasonably be expected to
have a Material Adverse Effect.

designed such disclosure controls and procedures to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods

applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws relating to, or affecting generally the enforcement of, creditors’ rights and remedies or by other equitable principles of general application.

Transaction Documents and the consummation by such Purchaser of the transactions contemplated hereby and thereby will not (i) result in a violation of the organizational documents of such Purchaser, (ii) conflict with, or constitute a

 13 

 (c) Investment Intent. Such Purchaser understands that the Securities are

minimum period of time and reserves the right, subject to the provisions of this Agreement and other Transaction Documents, at all times to sell or otherwise dispose of all or any part of such Securities pursuant to an effective registration

transactions in the future.

 ARTICLE IV. 
 OTHER AGREEMENTS OF THE PARTIES 
 4.1 Transfer Restrictions. 

(a) Compliance with Laws. Notwithstanding any other provision of this Article IV, the Purchaser covenants that the
Securities may be disposed of only pursuant to an effective registration statement under, and in compliance with the requirements of, the Securities Act, or pursuant to an available exemption from, or in a transaction not subject to, the
registration requirements of the Securities Act, and in compliance with any applicable state and federal securities laws. In connection with any transfer of the Securities other than (i) pursuant to an effective registration statement,
(ii) to the Company, (iii) pursuant to Rule 144 (provided that the Purchaser provides the Company with reasonable assurances (in the form of seller and, if applicable, broker representation letters) that the securities may be sold
pursuant to such rule) or (iv) in connection with a bona fide pledge as contemplated in Section 4.1(b), the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor and
reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Securities under the Securities Act. As
a condition of transfer, any such transferee shall agree in writing to be bound by the terms of this Agreement and the other Transaction Documents and shall have the rights of a Purchaser under this Agreement and the other Transaction Documents with
respect to such transferred Securities. 
 (b) Legends. Certificates evidencing the Securities shall bear any legend as
required by the “blue sky” laws of any state and a restrictive legend in substantially the following form, until such time as they are not required under Section 4.1(c): 

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), 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 OR (B) AN AVAILABLE EXEMPTION
FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS OR BLUE SKY LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY

 The Company acknowledges and agrees that a Purchaser may from time to time pledge, and/or grant a security
interest in, some or all of the legended Securities in connection with applicable securities laws, pursuant to a bona fide margin agreement in compliance with a bona fide margin loan. Such a pledge would not be subject to approval or consent of the
Company and no legal opinion of legal counsel to the pledgee, secured party or pledgor shall be required in connection with the pledge, but such legal opinion shall be required in connection with a subsequent transfer or foreclosure following
default by the Purchaser transferee of the pledge. No notice shall be required of such pledge, but Purchaser’s transferee shall promptly notify the Company of any such subsequent transfer or foreclosure. The Purchaser acknowledges that the
Company shall not be responsible for any pledges relating to, or the grant of any security interest in, any of the Securities or for any agreement, understanding or arrangement between any Purchaser and its pledgee or secured party. The Purchaser
acknowledges and agrees that, except as otherwise provided in Section 4.1(c), any Shares subject to a pledge or security interest as contemplated by this Section 4.1(b) shall continue to bear the legend set forth in this
Section 4.1(b) and be subject to the restrictions on transfer set forth in Section 4.1(a).

shall be removed and the Company shall issue a certificate without such legend or any other legend to the holder of the applicable Shares upon which it is stamped or issue to such holder by electronic delivery at the applicable balance account at
the Depository Trust Company (“DTC”), if (i) such Shares are registered for resale under the Securities Act (provided that, if the Purchaser is selling pursuant to an effective registration statement registering the Shares
for resale, the Purchaser agrees to only sell such Shares during such time that such registration statement is effective and not withdrawn or suspended, and only as permitted by such registration statement), (ii) such
Shares are sold or transferred pursuant to Rule 144 (if the transferor is not an Affiliate of the Company), or (iii) such Shares are eligible for sale under Rule 144, without the requirement for the Company to be in compliance with the current
public information required under Rule 144 as to such securities and without volume or manner-of-sale restrictions. Any fees (with respect to the Transfer Agent, Company Counsel or otherwise) associated with the issuance of any opinion for the
removal of such legend shall be borne by the Company. 
 (d) Acknowledgement. The Purchaser hereunder acknowledges its
primary responsibilities under the Securities Act and accordingly will not sell or otherwise transfer the Securities or any interest therein without complying with the requirements of the Securities Act. 

4.2 Principal Trading Market Listing. In the time and manner required by the Principal Trading Market, the Company shall prepare
and file with such Principal Trading Market an additional shares listing application covering all of the Shares and shall use its commercially reasonable efforts to take all steps necessary to cause all of the Shares to be approved for listing on
the Principal Trading Market as promptly as possible thereafter.

timely file a Form D with respect to the Securities as required under Regulation D and to provide a copy thereof, promptly upon the written request of the Purchaser. The Company, on or before the Closing Date, shall take such action as the
Company shall reasonably determine is necessary in order to obtain an exemption for or to qualify the Shares for sale to the Purchasers under applicable securities or “Blue Sky” laws of the states of the United States (or to obtain an
exemption from such qualification) and shall provide evidence of such actions promptly upon the written request of the Purchaser. 
 4.4 Short Sales and Confidentiality After The Date Hereof. The Purchaser shall not, and shall cause its Trading Affiliates not to, engage, directly or indirectly, in any transactions in the
Company’s securities (including, without limitation, any Short Sales involving the Company’s securities) during the period from the date hereof until the earlier of such time as (i) the transactions contemplated by this Agreement are
first publicly announced or (ii) this Agreement is terminated in full pursuant to Section 6.17. The Purchaser covenants that until such time as the transactions contemplated by this Agreement are publicly disclosed by the Company,
the Purchaser will maintain the confidentiality of the existence and terms of this transaction and the information included in the Transaction Documents and Disclosure Schedules. The Purchaser agrees that it will not enter into any Net Short Sales
(as hereinafter defined) from the period commencing on the Closing Date and ending on the earliest of (y) the twenty-four (24) month anniversary of the Closing Date or (z) the date that such Purchaser no longer holds any Shares. For
purposes of this Section 4.4, a “Net Short Sale” by any Purchaser shall mean a sale of Common Stock by such Purchaser that is marked as a short sale and that is made at a time when there is no equivalent offsetting long
position in Common Stock held by such Purchaser. 
 4.5 Use of Proceeds. Except as may otherwise be agreed to in writing
by the Company and the Purchaser, the Company shall use the net proceeds from the sale of the Debentures for debt reduction and other

Lacey and Jon Fitzgerald and such committee shall be solely and exclusively authorized to determine and direct the use of the net proceeds consistent with the terms of this Section 4.5). 

4.6 Reservation of Common Stock. As of the date hereof, the Company has reserved and the Company shall continue to reserve and
keep available at all times, free of preemptive rights, a sufficient number of shares of Common Stock for the purpose of enabling the Company to issue Shares pursuant to this Agreement and Shares issuable upon conversion of the Debentures.

any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or
omission of either party to exercise any right hereunder in any manner impair the exercise of any such right. 
 6.5
Construction. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof. The language used in this Agreement will be deemed to be the
language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party. This Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall
arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement or any of the Transaction Documents. 

  
 20 

 6.6 Successors and Assigns. The provisions of this Agreement shall inure to the
benefit of and be binding upon the parties and their successors and permitted assigns. This Agreement, or any rights or obligations hereunder, may not be assigned by the Company without the prior written consent of the Purchaser. The Purchaser may
assign its rights hereunder in whole or in part to any Person to whom such Purchaser assigns or transfers any Shares in compliance with the Transaction Documents and applicable law, provided such transferee shall agree in writing to be bound, with
respect to the transferred Shares, by the terms and conditions of this Agreement that apply to the “Purchasers”. 

6.7 No Third-Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective successors
and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person. 
 6.8
Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard
to the principles of conflicts of law thereof. Each party agrees that all Proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought
against a party hereto or its respective Affiliates, employees or agents) shall be commenced exclusively in the New York Courts. Each party hereto hereby irrevocably submits to the exclusive jurisdiction of the New York Courts for the adjudication
of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to
assert in any Proceeding, any claim that it is not personally subject to the jurisdiction of any such New York Court, or that such Proceeding has been commenced in an improper or inconvenient forum. Each party hereto hereby irrevocably waives
personal service of process and consents to process being served in any such Proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices
to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by
law. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED
HEREBY. 
 6.9 Survival. Subject to applicable statute of limitations, the representations, warranties, agreements
and covenants contained herein shall survive the Closing and the delivery of any Securities. 
 6.10 Execution. This
Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it
being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission, or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and
binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile signature page were an original thereof. 

6.11 Severability. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and
enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and
upon so agreeing, shall incorporate such substitute provision in this Agreement. 

  
 21 

 6.12 Rescission and Withdrawal Right. Notwithstanding anything to the contrary
contained in (and without limiting any similar provisions of) the Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its related
obligations within the periods therein provided, then such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice
to its future actions and rights. 
 6.13 Replacement of Securities. If any certificate or instrument evidencing any
Security is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution therefor, a new certificate or instrument, but only upon
receipt of evidence reasonably satisfactory to the Company and the Transfer Agent of such loss, theft or destruction and the execution by the holder thereof of a customary lost certificate affidavit of that fact and an agreement to indemnify and
hold harmless the Company and the Transfer Agent for any losses in connection therewith or, if required by the Transfer Agent, a bond in such form and amount as is required by the Transfer Agent. The applicants for a new certificate or instrument
under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement Shares. If a replacement certificate or instrument evidencing any Shares is requested due to a mutilation thereof, the Company
may require delivery of such mutilated certificate or instrument as a condition precedent to any issuance of a replacement. 

6.14 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of
damages, the Purchaser and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations
described in the foregoing sentence and hereby agree to waive in any action for specific performance of any such obligation (other than in connection with any action for a temporary restraining order) the defense that a remedy at law would be
adequate. 
 6.15 Payment Set Aside. To the extent that the Company makes a payment or payments to the Purchaser pursuant
to any Transaction Document or the Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or
preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other person under any law (including, without limitation, any bankruptcy law, state or
federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not
been made or such enforcement or setoff had not occurred. 
 6.16 Adjustments in Share Numbers and Prices. In the event
of any stock split, subdivision, dividend or distribution payable in shares of Common Stock (or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly shares of Common Stock), combination or
other similar recapitalization or event occurring after the date hereof and prior to the Closing, each reference in any Transaction Document to a number of shares or a price per share shall be deemed to be amended to appropriately account for such
event. 
 6.17 Termination. This Agreement may be terminated and the sale and purchase of the Securities abandoned at any
time prior to the Closing by either the Company or any Purchaser (with respect to itself only) upon written notice to the other, if the Closing has not been consummated on or prior to 5:00 P.M., New York

  
 22 

 
City time, on April 1, 2012; provided, however, that the right to terminate this Agreement under this Section 6.17 shall not be available to any Person whose failure to
comply with its obligations under this Agreement has been the cause of or resulted in the failure of the Closing to occur on or before such time. Nothing in this Section 6.17 shall be deemed to release any party from any liability for
any breach by such party of the terms and provisions of this Agreement or the other Transaction Documents or to impair the right of any party to compel specific performance by any other party of its obligations under this Agreement or the other
Transaction Documents.

 EXHIBIT B 
 FORM OF CONVERTIBLE DEBENTURE 

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS AND MAY
NOT BE REOFFERED, SOLD, TRANSFERRED, PLEDGED, OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO (1) REGISTRATION UNDER SUCH ACT OR LAWS OR (2) AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT OR LAWS. 

SENIOR CONVERTIBLE PROMISSORY NOTE 
  

			
	US $            	  	March     , 2012

 For value received, DayStar Technologies, Inc. a Delaware corporation (the “Company”), or its successor, promises to pay to
                    (the “Holder”) the principal sum of US
$                    on the terms set forth below. Interest on the outstanding principal amount shall accrue at the rate of 6% per annum
on and from the date of issuance. In the event this Note is outstanding and not paid in full on the Maturity Date, Interest shall thereafter accrue at the rate of 10% per annum. Interest shall accrue daily but need not be paid until the
Maturity Date. Interest shall be computed on the basis of a year of 365 days for the actual number of days elapsed. This Note is issued pursuant to that certain Securities Purchase Agreement by and among the Company and the Holder dated as of March
    , 2012 (the “Purchase Agreement”). Capitalized terms used but not defined herein shall have the meaning set forth in the Purchase Agreement. 
 1. Conversion of the Note 
 a. Conversion Timing
and Price. At any time after the issuance of this Note, the Holder may, by written notice to the Company, elect to convert all or any part of the outstanding principal plus any amount of accrued but unpaid interest into common stock of the
Company (the “Conversion Shares”) at a price per share equal to the last Closing Bid Price of the Company’s Common Stock on the Principal Trading Market prior to the execution of the Securities Purchase Agreement (subject to
adjustment in the event of any stock splits, stock dividends or other recapitalization of Common Stock subsequent to the date of such sale or issuance) (as adjusted, the “Conversion Price”). 

 b. Delivery of Conversion Shares. The Conversion Shares shall be
delivered as follows: 
 i. As promptly as practicable after conversion, the Company shall deliver to Holder, or
to such person or persons as are designated by Holder in the conversion notice, (1) a certificate or certificates representing the number of shares of common stock into which this Note or portion thereof is to be converted, in such name or
names as are specified in the Conversion Notice and (2) in the case of conversion of the entire remaining principal balance plus accrued unpaid interest hereof, any cash payable in respect of a fractional share. Such conversion shall be deemed
to have been effected at the close of business on the date when this Note shall have been surrendered to the Company for conversion, so that the person entitled to receive such Conversion Shares shall be treated for all purposes as having become the
record holder of such Conversion Shares at such time. 
 ii. In the event that less than the entire outstanding
principal and accrued unpaid interest of this Note is converted hereunder pursuant to subsection (a) above, this Note shall not be surrendered for cancellation but shall have the fact and amount of conversion recorded on the face of this Note
by writing acknowledged by Holder and the Company. If less than the entire principal balance of this Note is converted, the amount of principal converted shall be reduced to the nearest amount that results in no fractional shares. 

c. Reservation of Shares. The Company agrees that, during the period within which this Note may be converted, the Company will at
all times have authorized and in reserve, and will keep available solely for delivery upon the conversion of this Note, a sufficient number of shares of common stock and other securities and properties as from time to time shall be receivable upon
the conversion of this Note, free and clear of all restrictions on issuance, sale or transfer other than those imposed by law and free and clear of all pre-emptive rights. The Company agrees that the Conversion Shares shall, at the time of such
delivery, be validly issued and outstanding, fully paid and non-assessable, and the Company will take all such action as may be necessary to assure that the stated value or par value per share of the Conversion Shares is at all times equal to or
less than the Conversion Price. 
 d. Stockholder Approval. The Company shall not issue any shares of Common Stock upon
conversion of this Note if the issuance of such shares of Common Stock would exceed the aggregate number of shares of Common Stock which the Company may issue without breaching the Company’s obligations under the listing rules or regulations of
the Nasdaq Capital Market (the number if shares which may be issued without violating such rules and regulations, the “Exchange Cap”), except that such limitation shall not apply in the event that the Company obtains the approval of its
stockholders as required by the applicable rules of the Nasdaq Capital Market for issuances of shares of Common Stock in excess of such amount. Unless and until such approval is obtained, the Holder shall not be issued shares of Common Stock in an
amount greater than the Exchange Cap. This provision shall apply for the life of the transaction, even if the Company is no longer listed on the Nasdaq Capital Market.

 2. Payment of the Note – Term and Prepayment; Ranking 

a. Term. All principal and all unpaid accrued interest that has not been converted pursuant to Section 1 above shall be due
and payable on the one year anniversary of the date hereof (the “Maturity Date”). 
 b. Prepayment. This Note
may be prepaid in whole or in part at any time. 
 c. Ranking. Subject to the provisions of the immediately following
sentence, this Note and the rights and remedies of the Holder under this Note, shall be senior in right of payment to all other indebtedness of the Company, now or hereafter existing. Anything herein to the contrary notwithstanding, this Note and
the rights and remedies of the Holder under this Note shall be pari passu with the rights of payment of holders of existing senior debt of the Company (with respect to such senior debt) and any other note issued pursuant to the Purchase Agreement.

 3. Transfer 
 a. Assignment. In order to transfer this Note, Holder, or its duly authorized representative, shall provide Company a copy of an assignment duly executed by Holder hereof, but in no event shall
this Note be transferred to a third party unrelated to Holder, unless (i) an Event of Default has been declared by Holder and (ii) Company shall have received prior written notice of such transfer. In the event that Holder seeks to make a
transfer of this Note to an unrelated party in the absence of registration under the 1933 Act and any applicable state securities laws, Holder shall furnish an opinion of counsel satisfactory in form and in substance to Company that such transfer is
exempt from registration under the 1933 Act and any applicable state securities laws. For purposes of this Note, an Event of Default shall mean the failure of the Company to pay principal and/or interest when due. 

b. Legend. This Note is, and each certificate representing equity securities issued pursuant to Section 1 above shall be,
stamped or otherwise imprinted with a legend substantially in the following form: 
 “The securities represented hereby have
not been registered under the Securities Act of 1933, as amended, or applicable state securities laws and may not be reoffered, sold, transferred, pledged, or otherwise disposed of except pursuant to (1) registration under such act or laws or
(2) an exemption from registration under such act or laws.” 
 4. Waiver or Amendment. Any term of this Note may be
amended or waived with the written consent of the Company and Holder. The failure of Holder to enforce at any time any of the provisions of this Note shall not, absent an express written waiver signed by Holder specifying the provision being waived,
be construed to be a waiver of any such provision, nor in any way to affect the validity of this Note or any part hereof or the right of Holder thereafter to enforce each and every such provision. No waiver of any breach of this Note shall be held
to be a waiver of any other or subsequent breach. This Note is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provisions hereof be enforced by, any
other person. 

  
 3 

 Notices. All notices or other communications to a party required or permitted
hereunder shall be delivered as provided in Section 6.3 of the Purchase Agreement. 
 5. Headings. The titles and headings to
the sections herein are inserted for the convenience of reference only and are not intended to be a part of or to affect the meaning or interpretation of this Note. This Note shall be construed without regard to any presumption or other rule
requiring construction hereof against the party causing this Note to be drafted. 
 6. Governing Law; Waiver of Jury Trial. The
provisions of Section 6.8 of the Purchase Agreement are hereby incorporated by reference. 
 7. Usury. Notwithstanding
anything to the contrary contained herein, no provisions of this Note shall require the payment or permit the collection of interest in excess of the Maximum Lawful Rate. As used herein, the term “Maximum Lawful Rate” shall mean the
maximum lawful rate of interest which may be contracted for, charged, taken, received or reserved by Holder in accordance with the applicable laws of the State of New York.
