 RECITALS: 
 A. The Company and the Buyer are parties to a Securities Purchase Agreement dated as of May 25, 2006 (the “Agreement”). 

B. Capitalized terms used but not otherwise defined herein shall have the meanings ascribed in the Agreement. 
 C. Section 8(e) of the Agreement provides that the Agreement may be amended in a writing signed by the Company and the holders of at least a
majority of the aggregate number of Registrable Securities issued and issuable thereunder, and the Buyer is the holder of such a majority. 
 D. In consideration for this Amendment the Company is (i) agreeing to issue, subject to the terms hereof, to the Buyer or its designee a warrant (the “Warrant”) to purchase 317,394 shares of the Company’s common
stock, par value $0.01 per share (the “Common Stock”) pursuant to a Class A Warrant Agreement in the form attached hereto as Exhibit A, and (ii) entering into a Registration Rights Agreement with respect to the
shares issuable upon exercise of the Warrant. 
 E. Concurrently with the execution of this Amendment, the Buyer, the Company and LC Capital
Master Fund Ltd. are entering into a Note Purchase Agreement dated January 19, 2007 (the “Note Purchase Agreement”) whereby LC Capital Master Fund Ltd. will purchase the Note and certain associated rights from the Buyer.

 NOW, THEREFORE, the Company and the Buyer hereby agree as follows: 
 1. Representations and Warranties of the Company. The Company hereby represents and warrants to the Buyer as follows: 
 1.1 Authorization, etc. The Company has full power and authority to execute and deliver this Amendment and to carry out the transactions contemplated hereby. This Amendment has been duly executed and delivered
by the Company. This Amendment constitutes a valid and binding agreement of the Company, assuming the due execution of this Amendment by the Buyer, enforceable against the Company in accordance with its terms, except that (i) such enforcement
may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect relating to creditors’ rights generally and (ii) the remedy of specific performance and injunctive and other forms of
equitable relief may be subject to equitable defenses and to the discretion of the court before which any proceeding therefor may be brought. 

 1.2 The authorized capital stock of the Company consists of 60,000,000 shares of Common Stock, of which
7,823,707 shares are issued and outstanding as of the date hereof, and 3,000,000 shares of Preferred Stock, of which 0 shares are issued and outstanding as of the date hereof, and the Company has reserved 317,394 shares of Common Stock for issuance
upon the exercise of the Warrants. 
 2. Representations and Warranties of the Buyer. The Buyer hereby represents and warrants to the
Company as follows: 
 2.1 Authorization, etc. The Buyer has full power and authority to execute and deliver this Amendment and to
carry out the transactions contemplated hereby. This Amendment has been duly executed and delivered by the Buyer. This Amendment constitutes a valid and binding agreement of the Buyer, assuming the due execution of this Amendment by the Company,
enforceable against the Buyer in accordance with its terms, except that (i) such enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect relating to creditors’
rights generally and (ii) the remedy of specific performance and injunctive and other forms of equitable relief may be subject to equitable defenses and to the discretion of the court before which any proceeding therefor may be brought.

 3. Amendment of Agreement. Following the consummation of the sale of the Note pursuant to the Note Purchase Agreement and issuance
of the Common Stock to the Buyer, Section 4 of the Agreement shall be deleted in its entirety and be of no further force or effect. 
 4. Acknowledgment of Warrant Exercise Price. The Company and the Buyer acknowledge that following the transaction contemplated by this Amendment and by the Note Purchase Agreement, the exercise price of the Class A Warrants
purchased by the Buyer on May 25, 2006 will be $2.00 per share (subject to further adjustment from time to time as provided therein). 

 5. Insufficient Authorized Shares. Immediately following the date hereof, if at any time while the
Warrant remains outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance upon exercise of the Warrant at least a number of shares of Common Stock
equal to the number of shares of Common Stock issuable upon exercise of the Warrant (an “Authorized Share Failure”), the Company shall take all action necessary to increase the Company’s authorized shares of Common Stock to an
amount sufficient to allow the Company to reserve such number of shares of Common Stock then issuable upon exercise of the Warrant. Immediately following the date hereof, the Company shall use its best efforts to obtain a waiver from the Nasdaq
Capital Market regarding its obligations under Rule 4350 and any other applicable laws, rules or regulations, and in the event such waiver is not obtained, the Company shall provide each stockholder entitled to vote at a special or annual meeting of
stockholders of the Company, which shall be promptly called and held not later than March 30, 2007, a proxy statement soliciting each such stockholder’s affirmative vote for approval of resolutions providing for, without limitation, the
Company’s issuance of all of the shares issuable upon exercise of the Warrant, in accordance with applicable law and the rules and regulations of the Nasdaq Capital Market (such affirmative approval or waiver being referred to herein as the
“Stockholder Approval”). In no event will the Company seek a waiver or the affirmative vote of the stockholder’s of the Company for the issuance of any capital stock unless it has previously received the waiver or approval
permitting the issuance of all of the shares issuable upon conversion of the Warrant or simultaneously with such approval receives the waiver of approval of the issuance of all of the shares issuable upon conversion of the Warrant. The Company
shall, in the event the Stockholder Approval is not obtained, cause additional similar stockholder meetings to be held every three (3) months thereafter until the Stockholder Approval is obtained. Without limiting the generality of the
foregoing, as soon as practicable after the date of the occurrence of any other Authorized Share Failure, but in no event later than ninety (90) days after the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its
stockholders for the approval of an increase in the number of authorized shares of Common Stock. In connection with all such meetings, the Company shall provide a draft of the proxy statement to the Buyer and its counsel for review, provide each
stockholder with a proxy statement and shall use its best efforts to solicit its stockholders’ approval of such issuance of shares of Common Stock or such increase in authorized shares of Common Stock and to cause its Board of Directors to
recommend to its stockholders that they approve such proposal. 
 6. No Other Changes. Except as amended hereby, the Agreement shall
remain in full force and effect and in accordance with its terms. This Amendment shall be limited solely for the purpose and to the extent expressly set forth herein and nothing express or implied shall constitute an amendment, supplement,
modification or waiver to any of other term, provision or condition of the Agreement. 
 7. Agreement to Issue Warrant. The Company
agrees to issue the Warrant to the Buyer on the earlier to occur of the following: (i) the business day next following the date on which Nasdaq notifies the Company that it will not waive compliance by the Company with Rule 4350 in connection
with the issuance of the Warrant and (ii) the business day which is ten (10) calendar days after the Company notifies its shareholders that Nasdaq has waived the Company’s compliance with Rule 4350 as such Rule applies to the issuance
of the Warrant or the shares that may be received upon exercise of the Warrant. 

 8. Expenses. The Company agrees to pay the reasonable and actual fees and expenses of the Buyer
paid to third parties in connection with the negotiation, preparation, execution and delivery of this Amendment, the Registration Rights Agreement, the Note Purchase Agreement and the Class A Warrant Agreement and the past negotiations between
the Company and the Buyer. 
 9. Waiver of Default. Upon the issuance of the Common Stock to the Buyer as contemplated hereby and the
consummation of the sale of the Note under the Note Purchase Agreement, the Buyer hereby waives any default and any event of default, whether now existing or that will exist following the giving of notice or the passage of time or both. 

10. Counterparts. This Amendment may be executed and delivered (including by facsimile and PDF transmission) in two or more counterparts, and
by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same Amendment. 
 11. Governing Law. This Amendment shall be governed by and construed under the laws of the State of New York (without regard to conflicts of law
principles).

 REGISTRATION RIGHTS AGREEMENT (this “Agreement”), dated as of January 19, 2007, by and between DayStar Technologies, Inc., a

 2. Registration. 
 a. Mandatory Registration. The Company shall prepare, and, as soon as practicable, but in no event later than the Filing Deadline, file with the
SEC the Registration Statement on Form S-3 covering the resale of all of the Registrable Securities. In the event that 

 
Form S-3 is unavailable for such a registration, the Company shall use Form SB-2 or such other form as is available for such a registration on another
appropriate form reasonably acceptable to the Required Holders, subject to the provisions of Section 2(d). The Registration Statement prepared pursuant hereto shall register for resale at least the number of shares of Common Stock equal to the
Required Registration Amount as of date the Registration Statement is initially filed with the SEC. The Registration Statement shall contain (except if otherwise directed by the Required Holders) the “Selling Shareholders” and
“Plan of Distribution” sections in substantially the form attached hereto as Exhibit B. The Company shall use its best efforts to have the Registration Statement declared effective by the SEC as soon as practicable, but in no
event later than the Effectiveness Deadline. Investors shall prior to registration, and the Buyer shall no later than five (5) Business Days after the Closing Date (unless it has already provided the same to the Company), provide the Company
with a fully completed and executed Investor Questionnaire, in the form attached hereto as Exhibit C. Investors shall, as provided in Section 4 below, cooperate with the Company as reasonably requested by the Company in connection
with the preparation and filing of any Registration Statement hereunder. If the effectiveness of the Registration Statement is delayed beyond the Effectiveness Deadline directly as a result of any action or inaction solely on the part of Buyer, the
Effectiveness Deadline shall be extended by the period of time attributable to such delay. 
 b. Allocation of Registrable
Securities. The initial number of Registrable Securities included in any Registration Statement and any increase in the number of Registrable Securities included therein shall be allocated pro rata among the Investors based on the number of
Registrable Securities held by each Investor at the time the Registration Statement covering such initial number of Registrable Securities or increase thereof is declared effective by the SEC. In the event that an Investor sells or otherwise
transfers any of such Investor’s Registrable Securities, each transferee shall be allocated a pro rata portion of the then remaining number of Registrable Securities included in such Registration Statement for such transferor. Any shares of
Common Stock included in a Registration Statement and which remain allocated to any Person which ceases to hold any Registrable Securities covered by such Registration Statement shall be allocated to the remaining Investors, pro rata based on the
number of Registrable Securities then held by such Investors which are covered by such Registration Statement. The Company may include securities other than Registrable Securities on any Registration Statement without the prior written consent of
the Required Holders. 
 c. Legal Counsel. Subject to Section 5 hereof, the Required Holders shall have the right to select one
legal counsel to review and oversee any registration pursuant to this Section 2 (“Legal Counsel”), which shall be McDermott Will & Emery LLP or such other counsel as thereafter designated by the Required Holders. The
Company and Legal Counsel shall reasonably cooperate with each other in performing the Company’s obligations under this Agreement. 
 d. Ineligibility for Form S-3. In the event that Form S-3 is not available for the registration of the resale of Registrable Securities hereunder, the Company shall (i) register the resale of the Registrable Securities on
another appropriate form reasonably acceptable to the Required Holders and (ii) undertake to register the Registrable Securities on Form S-3 as soon as such form is available, provided that the Company shall maintain the effectiveness of the
Registration Statement then in effect until such time as a Registration 

 
Statement on Form S-3 covering the Registrable Securities has been declared effective by the SEC. 
 e. Sufficient Number of Shares Registered. In the event the number of shares available under a Registration Statement filed pursuant to
Section 2(a) is insufficient to cover all of the Registrable Securities required to be covered by such Registration Statement or an Investor’s allocated portion of the Registrable Securities pursuant to Section 2(b), the Company shall
amend the applicable Registration Statement, or file a new Registration Statement (on the short form available therefor, if applicable), or both, so as to cover at least the Required Registration Amount as of the trading day immediately preceding
the date of the filing of such amendment or new Registration Statement, in each case, as soon as practicable, but in any event not later than fifteen (15) days after the necessity therefor arises. The Company shall use its best efforts to cause
such amendment and/or new Registration Statement to become effective as soon as practicable following the filing thereof. For purposes of the foregoing provision, the number of shares available under a Registration Statement shall be deemed
“insufficient to cover all of the Registrable Securities” if at any time the number of shares of Common Stock available for resale under the Registration Statement is less than the product determined by multiplying (i) the Required
Registration Amount as of such time by (ii) 0.90. The calculation set forth in the foregoing sentence shall be made without regard to any limitations on the exercise of the Warrants and such calculation shall assume that the Warrants are then
exercisable for shares of Common Stock at the then prevailing Exercise Price (as defined in the Warrants). 
 f. Effect of Failure to
File and Obtain and Maintain Effectiveness of Registration Statement. If (i) a Registration Statement covering all of the Registrable Securities required to be covered thereby and required to be filed by the Company pursuant to this
Agreement is (A) not filed with the SEC on or before the respective Filing Deadline (a “Filing Failure”) or (B) not declared effective by the SEC on or before the respective Effectiveness Deadline (an
“Effectiveness Failure”) or (ii) on any day after the Effective Date sales of all of the Registrable Securities required to be included on such Registration Statement cannot be made (other than during an Allowable Grace Period
(as defined in Section 3(r)) pursuant to such Registration Statement (including, without limitation, because of a failure to keep such Registration Statement effective, to disclose such information as is necessary for sales to be made pursuant
to such Registration Statement or to register a sufficient number of shares of Common Stock) (a “Maintenance Failure”) then, as partial relief for the damages to any holder by reason of any such delay in or reduction of its ability
to sell the underlying shares of Common Stock (which remedy shall not be exclusive of any other remedies available at law or in equity), the Company shall pay to the holders of Registrable Securities relating to such Registration Statement an
aggregate amount in cash of $25,000 on every thirtieth day (pro rated for periods totaling less than thirty days) after a Filing Failure until such Filing Failure is cured; (ii) the day of an Effectiveness Failure and on every thirtieth day
(pro rated for periods totaling less than thirty days) after an Effectiveness Failure until such Effectiveness Failure is cured; and (iii) the initial day of a Maintenance Failure and on every thirtieth day (pro rated for periods totaling less
than thirty days) after a Maintenance Failure until such Maintenance Failure is cured. In addition to the foregoing, if the Registration Statement is not declared effective by the SEC on or prior to 120 days after the Closing Date, the Company shall
pay to each holder of Registrable Securities relating to such Registration Statement an additional delay payment in cash of $25,000. The 

 
payments to which a holder shall be entitled pursuant to this Section 2(f) are referred to herein as “Registration Delay Payments.”
Registration Delay Payments shall be capped at an aggregate of $100,000. Registration Delay Payments shall be paid on the day of the Filing Failure, Effectiveness Failure and the initial day of a Maintenance Failure, as applicable, and thereafter on
the earlier of (I) the thirtieth day after the event or failure giving rise to the Registration Delay Payments has occurred and (II) the third Business Day after the event or failure giving rise to the Registration Delay Payments is cured. In
the event the Company fails to make Registration Delay Payments in a timely manner, such Registration Delay Payments shall bear interest at the rate of one percent (1.0%) of the total amount of the Registration Delay Payments per month
(prorated for partial months) until paid in full. Notwithstanding the foregoing, no Registration Delay Payments shall be due or payable if any delay or failure to file a Registration Statement or Maintenance Failure is directly caused by statements,
omissions, action or inaction solely on the part of the Buyer. 
 3. Related Obligations. 
 At such time as the Company is obligated to file a Registration Statement with the SEC pursuant to Section 2(a), 2(d) or 2(e), the Company will use
its best efforts to effect the registration of the Registrable Securities in accordance with the intended method of disposition thereof and, pursuant thereto, the Company shall have the following obligations: 
 a. The Company shall promptly prepare and file with the SEC a Registration Statement with respect to the Registrable Securities and use its best efforts
to cause such Registration Statement relating to the Registrable Securities to become effective as soon as practicable after such filing (but in no event later than the Effectiveness Deadline) with respect to filings pursuant to Section 2(a).
The Company shall keep each Registration Statement effective pursuant to Rule 415 at all times until the earlier of (i) the date as of which the Investors may sell all of the Registrable Securities covered by such Registration Statement without
restriction pursuant to Rule 144(k) (or any successor thereto) promulgated under the 1933 Act or (ii) the date on which the Investors shall have sold all of the Registrable Securities covered by such Registration Statement (the
“Registration Period”). The Company shall ensure that each Registration Statement (including any amendments or supplements thereto and prospectuses contained therein) shall not contain any untrue statement of a material fact or omit
to state a material fact required to be stated therein, or necessary to make the statements therein (in the case of prospectuses, in the light of the circumstances in which they were made) not misleading. The term “best efforts” shall
mean, among other things, that the Company shall submit to the SEC, within two (2) Business Days after the later of the date that (i) the Company learns that no review of a particular Registration Statement will be made by the staff of the
SEC or that the staff has no further comments on a particular Registration Statement, as the case may be, and (ii) the approval of Legal Counsel pursuant to Section 3(c) (which approval is immediately sought), a request for acceleration of
effectiveness of such Registration Statement to a time and date not later than 48 hours after the submission of such request. 
 b. The
Company shall prepare and file with the SEC such amendments (including post-effective amendments) and supplements to a Registration Statement and the prospectus used in connection with such Registration Statement, which prospectus is to be filed
pursuant to Rule 424 promulgated under the 1933 Act, as may be necessary to keep such 

 
Registration Statement effective at all times during the Registration Period, and, during such period, comply with the provisions of the 1933 Act with
respect to the disposition of all Registrable Securities of the Company covered by such Registration Statement until such time as all of such Registrable Securities shall have been disposed of in accordance with the intended methods of disposition
by the seller or sellers thereof as set forth in such Registration Statement. In the case of amendments and supplements to a Registration Statement which are required to be filed pursuant to this Agreement (including pursuant to this
Section 3(b)) by reason of the Company filing a report on Form 10-Q, Form 10-K or any analogous report under the Securities Exchange Act of 1934, as amended (the “1934 Act”), the Company shall have incorporated such report by
reference into such Registration Statement, if applicable, or shall file such amendments or supplements with the SEC on the same day on which the 1934 Act report is filed which created the requirement for the Company to amend or supplement such
Registration Statement. 
 c. The Company shall (A) permit Legal Counsel to review and comment upon (i) the Registration Statement
at least one (1) Business Day prior to its filing with the SEC and (ii) all amendments and supplements to the Registration Statement (except for Annual Reports on Form 10-K, and Reports on Form 10-Q and any similar or successor reports)
within a reasonable number of days prior to their filing with the SEC, and (B) not file any Registration Statement or amendment or supplement thereto in a form to which Legal Counsel reasonably objects. The Company shall furnish to Legal
Counsel, without charge, unless otherwise available on EDGAR, (i) copies of any correspondence from the SEC or the staff of the SEC to the Company or its representatives relating to any Registration Statement, (ii) promptly after the same
is prepared and filed with the SEC, one copy of any Registration Statement and any amendment(s) thereto, including financial statements and schedules, all documents incorporated therein by reference, if requested by an Investor, and all exhibits and
(iii) upon the effectiveness of any Registration Statement, one copy of the prospectus included in such Registration Statement and all amendments and supplements thereto. The Company shall reasonably cooperate with Legal Counsel in performing
the Company’s obligations pursuant to this Section 3. 
 d. The Company shall furnish to each Investor whose Registrable
Securities are included in any Registration Statement, without charge, (i) unless otherwise available on EDGAR, promptly after the same is prepared and filed with the SEC, at least one copy of such Registration Statement and any amendment(s)
thereto, including financial statements and schedules, all documents incorporated therein by reference, if requested by an Investor, all exhibits and each preliminary prospectus, (ii) upon the effectiveness of any Registration Statement, ten
(10) copies of the prospectus included in such Registration Statement and all amendments and supplements thereto (or such other number of copies as such Investor may reasonably request) and (iii) such other documents, including copies of
any preliminary or final prospectus, as such Investor may reasonably request from time to time in order to facilitate the disposition of the Registrable Securities owned by such Investor. 
 e. The Company shall use its best efforts to (i) register and qualify, unless an exemption from registration and qualification applies, the resale
by Investors of the Registrable Securities covered by a Registration Statement under such other securities or “blue sky” laws of all applicable jurisdictions in the United States, (ii) prepare and file in those jurisdictions, such
amendments (including post-effective amendments) and supplements to such 

 
registrations and qualifications as may be necessary to maintain the effectiveness thereof during the Registration Period, (iii) take such other actions
as may be necessary to maintain such registrations and qualifications in effect at all times during the Registration Period, and (iv) take all other actions reasonably necessary or advisable to qualify the Registrable Securities for sale in
such jurisdictions; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to (x) qualify to do business in any jurisdiction where it would not otherwise be required to qualify but for this
Section 3(e), (y) subject itself to general taxation in any such jurisdiction, or (z) file a general consent to service of process in any such jurisdiction. The Company shall promptly notify Legal Counsel and each Investor who holds
Registrable Securities of the receipt by the Company of any notification with respect to the suspension of the registration or qualification of any of the Registrable Securities for sale under the securities or “blue sky” laws of any
jurisdiction in the United States or its receipt of notice of the initiation or threatening of any proceeding for such purpose. 
 f. The
Company shall notify Legal Counsel and each Investor in writing of the happening of any event, as promptly as practicable after becoming aware of such event, as a result of which the prospectus included in a Registration Statement, as then in
effect, includes an untrue statement of a material fact or omission to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading
(provided, that in no event shall such notice contain any material, nonpublic information), and, subject to Section 3(r), promptly prepare a supplement or amendment to such Registration Statement to correct such untrue statement or
omission, and deliver ten (10) copies of such supplement or amendment to Legal Counsel and each Investor (or such other number of copies as Legal Counsel or such Investor may reasonably request). The Company shall also promptly notify Legal
Counsel and each Investor in writing (i) when a prospectus or any prospectus supplement or post-effective amendment has been filed, and when a Registration Statement or any post-effective amendment has become effective (notification of such
effectiveness shall be delivered to Legal Counsel and each Investor by facsimile or e-mail on the same day of such effectiveness and by overnight mail), (ii) of any request by the SEC for amendments or supplements to a Registration Statement or
related prospectus or related information, and (iii) of the Company’s reasonable determination that a post-effective amendment to a Registration Statement would be appropriate. 
 g. The Company shall use its best efforts to prevent the issuance of any stop order or other suspension of effectiveness of a Registration Statement, or
the suspension of the qualification of any of the Registrable Securities for sale in any jurisdiction and, if such an order or suspension is issued, to obtain the withdrawal of such order or suspension at the earliest possible moment and to notify
Legal Counsel and each Investor who holds Registrable Securities being sold of the issuance of such order or suspension and the resolution thereof or its receipt of notice of the initiation or threat of any proceeding for such purpose. 

h. At the reasonable request of any Investor, the Company shall furnish to such Investor, on the date of the effectiveness of the Registration
Statement and thereafter from time to time on such dates as an Investor may reasonably request (i) a letter, dated such date, from the Company’s independent certified public accountants in form and substance as is customarily given by
independent certified public accountants to underwriters in an underwritten public offering, addressed to the Investors, and (ii) an opinion, dated as of such date, of counsel 

 
representing the Company for purposes of such Registration Statement, in form, scope and substance as is customarily given in an underwritten public
offering, addressed to the Investors. 
 i. The Company shall make available for inspection by (i) any Investor, (ii) Legal
Counsel and (iii) one firm of accountants or other agents retained by the Investors (collectively, the “Inspectors”), all pertinent financial and other records, and pertinent corporate documents and properties of the Company
(collectively, the “Records”), as shall be reasonably deemed necessary by each Inspector, and cause the Company’s officers, directors and employees, counsel and the Company’s independent certified public accountants to
supply all information which may be necessary and any Inspector may reasonably request; provided, however, that each Inspector shall agree to hold in strict confidence and shall not make any disclosure (except to an Investor) or use of
any Record or other information which the Company determines in good faith to be confidential, and of which determination the Inspectors are so notified, unless (a) the release of such Records is ordered pursuant to a final, non-appealable
subpoena or order from a court or government body of competent jurisdiction or (b) the information in such Records has been made generally available to the public other than by disclosure in violation of this or any other agreement of which the
Inspector has knowledge. Each Investor agrees that it shall, upon learning that disclosure of such Records is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt notice to the Company and allow
the Company, at its expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, the Records deemed confidential. Nothing herein (or in any other confidentiality agreement between the Company and any
Investor) shall be deemed to limit the Investors’ ability to sell Registrable Securities in a manner which is otherwise consistent with applicable laws and regulations. 
 j. The Company shall hold in confidence and not make any disclosure of information concerning an Investor provided to the Company unless
(i) disclosure of such information is necessary to comply with federal or state securities laws, (ii) the disclosure of such information is necessary to avoid or correct a misstatement or omission in any Registration Statement,
(iii) the release of such information is ordered pursuant to a subpoena or other final, non-appealable order from a court or governmental body of competent jurisdiction, or (iv) such information has been made generally available to the
public other than by disclosure in violation of this Agreement or any other agreement. The Company agrees that it shall, upon learning that disclosure of such information concerning an Investor is sought in or by a court or governmental body of
competent jurisdiction or through other means, give prompt written notice to such Investor and allow such Investor, at the Investor’s expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, such
information. 
 k. The Company shall use its best efforts to cause all of the Registrable Securities covered by a Registration Statement to
be listed on the securities exchange on which securities of the same class or series issued by the Company are then listed. The Company shall pay all fees and expenses in connection with satisfying its obligation under this Section 3(k).

 l. The Company shall cooperate with the Investors who hold Registrable Securities being offered and, to the extent applicable, facilitate
the timely preparation and delivery of certificates (not bearing any restrictive legend) representing the Registrable Securities to be offered pursuant to a Registration Statement and enable such certificates to be in such 

 
denominations or amounts, as the case may be, as the Investors may reasonably request and registered in such names as the Investors may request. 

m. If requested by an Investor, the Company shall within five (5) days of receipt of notice from such Investor (i) incorporate in a
prospectus supplement or post-effective amendment such information as an Investor reasonably requests to be included therein relating to the sale and distribution of Registrable Securities, including, without limitation, information with respect to
the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering; (ii) make all required filings of such prospectus
supplement or post-effective amendment after being notified of the matters to be incorporated in such prospectus supplement or post-effective amendment; and (iii) supplement or make amendments to any Registration Statement if reasonably
requested by an Investor holding any Registrable Securities. 
 n. The Company shall use its best efforts to cause the Registrable
Securities covered by the Registration Statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to consummate the disposition of such Registrable Securities. 
 o. The Company shall make generally available to its security holders as soon as practical, but not later than ninety (90) days after the close of
the period covered thereby, an earnings statement (in form complying with, and in the manner provided by, the provisions of Rule 158 under the 1933 Act) covering a twelve-month period beginning not later than the first day of the Company’s
fiscal quarter next following the Effective Date of the Registration Statement. 
 p. The Company shall otherwise use its best efforts to
comply with all applicable rules and regulations of the SEC in connection with any registration hereunder. 
 q. Within two
(2) Business Days after a Registration Statement which covers Registrable Securities is ordered effective by the SEC, the Company shall deliver, and shall cause legal counsel for the Company to deliver, to the transfer agent for such
Registrable Securities (with copies to the Investors whose Registrable Securities are included in such Registration Statement) confirmation that such Registration Statement has been declared effective by the SEC in the form attached hereto as
Exhibit A. 
 r. Notwithstanding anything to the contrary contained herein, at any time after the Registration Statement has been
declared effective by the SEC, the Company may delay the disclosure of material, non-public information concerning the Company the disclosure of which at the time is not, in the good faith opinion of the Board of Directors of the Company and its
counsel (following consultation with its counsel), in the best interest of the Company and, in the opinion of counsel to the Company, otherwise required (a “Grace Period”); provided, that the Company shall promptly
(i) notify the Investors in writing of the existence of material, non-public information giving rise to a Grace Period (provided, that in each notice the Company will not disclose the content of such material, non-public information to
the Investors) and the date on which the Grace Period will begin, and (ii) notify the Investors in writing of the date on which the Grace Period ends; and provided, further, that no Grace Period shall exceed ten (10)

 
consecutive days and during any three hundred sixty five (365) day period such Grace Periods shall not exceed an aggregate of thirty (30) days and
the first day of any Grace Period must be at least two (2) trading days after the last day of any prior Grace Period (each, an “Allowable Grace Period”). For purposes of determining the length of a Grace Period above, the Grace
Period shall begin on and include the date the Investors receive the notice referred to in clause (i) and shall end on and include the later of the date the Investors receive the notice referred to in clause (ii) and the date referred to
in such notice. The provisions of Section 3(g) hereof shall not be applicable during the period of any Allowable Grace Period. Upon expiration of the Grace Period, the Company shall again be bound by the first sentence of Section 3(f) with
respect to the information giving rise thereto unless such material, non-public information is no longer applicable. Notwithstanding anything to the contrary contained herein, the Company shall cause its transfer agent to deliver unlegended shares
of Common Stock to a transferee of an Investor in accordance with the terms of the Securities Purchase Agreement in connection with any sale of Registrable Securities with respect to which an Investor has entered into a contract for sale, and
delivered a copy of the prospectus included as part of the applicable Registration Statement, prior to the Investor’s receipt of the notice of a Grace Period and for which the Investor has not yet settled. 
 4. Obligations of the Investors. 
 a.
At least five (5) Business Days prior to the first anticipated filing date of a Registration Statement, the Company shall notify each Investor in writing of the information the Company requires from each such Investor if such Investor elects to
have any of such Investor’s Registrable Securities included in such Registration Statement. It shall be a condition precedent to the obligations of the Company to complete the registration pursuant to this Agreement with respect to the
Registrable Securities of a particular Investor that such Investor shall furnish to the Company such information regarding itself, the Registrable Securities held by it and the intended method of disposition of the Registrable Securities held by it,
as shall be reasonably required to effect and maintain the effectiveness of the registration of such Registrable Securities and shall execute such documents in connection with such registration as the Company may reasonably request. 
 b. Each Investor, by such Investor’s acceptance of the Registrable Securities, agrees to cooperate with the Company as reasonably requested by the
Company in connection with the preparation and filing of any Registration Statement hereunder, unless such Investor has notified the Company in writing of such Investor’s election to exclude all of such Investor’s Registrable Securities
from such Registration Statement. 
 c. Each Investor agrees that, upon receipt of any notice from the Company of the happening of any event
of the kind described in Section 3(g) or the first sentence of Section 3(f), such Investor will immediately discontinue disposition of Registrable Securities pursuant to any Registration Statement(s) covering such Registrable Securities
until such Investor’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 3(g) or the first sentence of Section 3(f) or receipt of notice that no supplement or amendment is required. Notwithstanding
anything to the contrary contained herein, the Company shall cause its transfer agent to deliver unlegended shares of Common Stock to a transferee of an Investor in accordance with the terms of the Securities Purchase Agreement in 

 
connection with any sale of Registrable Securities with respect to which an Investor has entered into a contract for sale prior to the Investor’s
receipt of a notice from the Company of the happening of any event of the kind described in Section 3(g) or the first sentence of Section 3(f) and for which the Investor has not yet settled. 
 d. Each Investor covenants and agrees that it will comply with the prospectus delivery requirements of the 1933 Act as applicable to it in connection
with sales of Registrable Securities pursuant to the Registration Statement. 
 5. Expenses of Registration. 
 All reasonable expenses, other than underwriting discounts and commissions, incurred in connection with registrations, filings or qualifications pursuant
to Sections 2 and 3, including, without limitation, all registration, listing and qualifications fees, printers and accounting fees, and fees and disbursements of counsel for the Company shall be paid by the Company. The Company shall also reimburse
the Investors for the reasonable fees and disbursements of Legal Counsel in connection with registration, filing or qualification pursuant to Sections 2 and 3 of this Agreement which amount shall be limited to $10,000 in the aggregate. 

6. Indemnification. 
 In the event
any Registrable Securities are included in a Registration Statement under this Agreement: 
 a. To the fullest extent permitted by law, the
Company will, and hereby does, indemnify, hold harmless and defend each Investor, the directors, officers, members, partners, employees, agents and representatives of, and each Person, if any, who controls any Investor within the meaning of the 1933
Act or the 1934 Act (each, an “Indemnified Person”), against any losses, claims, damages, liabilities, judgments, fines, penalties, charges, costs, reasonable attorneys’ fees, amounts paid in settlement or expenses, joint or
several (collectively, “Claims”) incurred in investigating, preparing or defending any action, claim, suit, inquiry, proceeding, investigation or appeal taken from the foregoing by or before any court or governmental, administrative
or other regulatory agency, body or the SEC, whether pending or threatened, whether or not an Indemnified Person is or may be a party thereto (“Indemnified Damages”), to which any of them may become subject insofar as such Claims
(or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of a material fact in a Registration Statement or any post-effective amendment
thereto or in any filing made in connection with the qualification of the offering under the securities or other “blue sky” laws of any jurisdiction in which Registrable Securities are offered (“Blue Sky Filing”), or the
omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) any untrue statement or alleged untrue statement of a material fact contained in any
preliminary prospectus if used prior to the effective date of such Registration Statement, or contained in the final prospectus (as amended or supplemented, if the Company files any amendment thereof or supplement thereto with the SEC) or the
omission or alleged omission to state therein any material fact necessary to make the statements made therein, in light of the circumstances under which the statements therein were made, not misleading, (iii)

 
any violation or alleged violation by the Company of the 1933 Act, the 1934 Act, any other law, including, without limitation, any state securities law, or
any rule or regulation thereunder relating to the offer or sale of the Registrable Securities pursuant to a Registration Statement or (iv) any violation of this Agreement (the matters in the foregoing clauses (i) through (iv) being,
collectively, “Violations”). Subject to Section 6(c), the Company shall reimburse the Indemnified Persons, promptly as such expenses are incurred and are due and payable, for any reasonable legal fees or other reasonable
expenses incurred by them in connection with investigating or defending any such Claim. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(a): (i) shall not apply to a Claim
by an Indemnified Person arising out of or based upon a Violation which occurs in reliance upon and in conformity with information furnished in writing to the Company by such Indemnified Person for such Indemnified Person expressly for use in
connection with the preparation of the Registration Statement or any such amendment thereof or supplement thereto, if such prospectus was timely made available by the Company pursuant to Section 3(d); (ii) with respect to any preliminary
prospectus, shall not inure to the benefit of any such Person from whom the Person asserting any such Claim purchased the Registrable Securities that are the subject thereof (or to the benefit of any Person controlling such Person) if the untrue
statement or omission of material fact contained in the preliminary prospectus was corrected in the prospectus, as then amended or supplemented, if such prospectus was timely made available by the Company pursuant to Section 3(d), and the
Indemnified Person was promptly advised in writing not to use the incorrect prospectus prior to the use giving rise to a violation and such Indemnified Person, notwithstanding such advice, used it or failed to deliver the correct prospectus as
required by the 1933 Act and such correct prospectus was timely made available pursuant to Section 3(d); (iii) shall not be available to the extent such Claim is based on a failure of the Investor to deliver or to cause to be delivered the
prospectus made available by the Company, including a corrected prospectus, if such prospectus or corrected prospectus was timely made available by the Company pursuant to Section 3(d); and (iv) shall not apply to amounts paid in
settlement of any Claim if such settlement is effected without the prior written consent of the Company, which consent shall not be unreasonably withheld, conditioned or delayed. Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of the Indemnified Person and shall survive the transfer of the Registrable Securities by the Investors pursuant to Section 9. 
 b. In connection with any Registration Statement in which an Investor is participating, each such Investor agrees to severally and not jointly indemnify, hold harmless and defend, to the same extent and in the same
manner as is set forth in Section 6(a), the Company, each of its directors, each of its officers who signs the Registration Statement and each Person, if any, who controls the Company within the meaning of the 1933 Act or the 1934 Act (each, an
“Indemnified Party”), against any Claim or Indemnified Damages to which any of them may become subject, under the 1933 Act, the 1934 Act or otherwise, insofar as such Claim or Indemnified Damages arise out of or are based upon any
Violation, in each case to the extent, and only to the extent, that such Violation occurs in reliance upon and in conformity with written information furnished to the Company by such Investor expressly for use in connection with such Registration
Statement; and, subject to Section 6(c), such Investor will reimburse any legal or other expenses reasonably incurred by an Indemnified Party in connection with investigating or defending any such Claim; provided, however, that
the indemnity agreement contained in this Section 6(b) and the agreement with respect to contribution contained in Section 7 shall not 

 
apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of such Investor, which consent shall not
be unreasonably withheld, conditioned or delayed; provided, further, however, that the Investor shall be liable under this Section 6(b) for only that amount of a Claim or Indemnified Damages as does not exceed the net
proceeds to such Investor as a result of the sale of Registrable Securities pursuant to such Registration Statement. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified Party
and shall survive the transfer of the Registrable Securities by the Investors pursuant to Section 9. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(b) with respect to
any preliminary prospectus shall not inure to the benefit of any Indemnified Party if the untrue statement or omission of material fact contained in the preliminary prospectus was corrected on a timely basis in the prospectus, as then amended or
supplemented. 
 c. Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the
commencement of any action or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this
Section 6, deliver to the indemnifying party a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other
indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified Party, as the case may be; provided, however,
that an Indemnified Person or Indemnified Party shall have the right to retain its own counsel with the fees and expenses of not more than one counsel for such Indemnified Person or Indemnified Party to be paid by the indemnifying party, if, in the
reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate due to actual or potential differing interests
between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding. In the case of an Indemnified Person, legal counsel referred to in the immediately preceding sentence shall be selected by the
Investors holding at least a majority in interest of the Registrable Securities included in the Registration Statement to which the Claim relates. The Indemnified Party or Indemnified Person shall cooperate reasonably with the indemnifying party in
connection with any negotiation or defense of any such action or Claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the Indemnified Party or Indemnified Person which relates to such
action or Claim. The indemnifying party shall keep the Indemnified Party or Indemnified Person fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. No indemnifying party shall be liable for
any settlement of any action, claim or proceeding effected without its prior written consent; provided, however, that the indemnifying party shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall,
without the prior written consent of the Indemnified Party or Indemnified Person, consent to entry of any judgment or enter into any settlement or other compromise which does not include as an unconditional term thereof the giving by the claimant or
plaintiff to such Indemnified Party or Indemnified Person of a release from all liability in respect to such Claim or litigation. Following indemnification as provided for hereunder, the indemnifying party shall be subrogated to all rights of the
Indemnified Party or Indemnified Person with respect to all third parties, firms or corporations relating to the matter for which 

 
indemnification has been made. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such
action shall not relieve such indemnifying party of any liability to the Indemnified Person or Indemnified Party under this Section 6, except to the extent that the indemnifying party is prejudiced in its ability to defend such action.

 d. The indemnification required by this Section 6 shall be made by periodic payments of the amount thereof during the course of the
investigation or defense, as and when bills are received or Indemnified Damages are incurred. 
 e. The indemnity agreements contained
herein shall be in addition to (i) any cause of action or similar right of the Indemnified Party or Indemnified Person against the indemnifying party or others and (ii) any liabilities the indemnifying party may be subject to pursuant to
the law. 
 7. Contribution. 
 To the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution with respect to any amounts for which it would otherwise be liable under
Section 6 to the fullest extent permitted by law; provided, however, that: (i) no Person involved in the sale of Registrable Securities who is guilty of fraudulent misrepresentation (within the meaning of Section 11(f)
of the 1933 Act) in connection with such sale shall be entitled to contribution from any Person involved in such sale of Registrable Securities who was not guilty of fraudulent misrepresentation; and (ii) contribution by any seller of
Registrable Securities shall be limited in amount to the net amount of proceeds received by such seller from the sale of such Registrable Securities pursuant to such Registration Statement. 
 8. Reports Under the 1934 Act. 
 With
a view to making available to the Investors the benefits of Rule 144 promulgated under the 1933 Act or any other similar rule or regulation of the SEC that may at any time permit the Investors to sell securities of the Company to the public without
registration (“Rule 144”), the Company agrees to: 
 a. make and keep public information available, as those terms are
understood and defined in Rule 144; 
 b. file with the SEC in a timely manner all reports and other documents required of the Company under
the 1933 Act and the 1934 Act so long as the Company remains subject to such requirements (it being understood that nothing herein shall limit the Company’s obligations under Section 4(b) of the Securities Purchase Agreement) and the
filing of such reports and other documents is required for the applicable provisions of Rule 144; and 
 c. furnish to each Investor so long
as such Investor owns Registrable Securities, promptly upon request, (i) a written statement by the Company, if true, that it has complied with the reporting requirements of Rule 144, the 1933 Act and the 1934 Act, (ii) a copy of the most
recent annual or quarterly report of the Company and such other reports and 

 
documents so filed by the Company, and (iii) such other information as may be reasonably requested to permit the Investors to sell such securities
pursuant to Rule 144 without registration. 
 9. Assignment of Registration Rights. 
 The rights under this Agreement shall be automatically assignable by the Investors to any transferee of all or any portion of such Investor’s
Registrable Securities if: (i) the Investor agrees in writing with the transferee or assignee to assign such rights and a copy of such agreement is furnished to the Company within a reasonable time after such assignment; (ii) the Company
is, within a reasonable time after such transfer or assignment, furnished with written notice of (a) the name and address of such transferee or assignee and (b) the securities with respect to which such registration rights are being
transferred or assigned; (iii) immediately following such transfer or assignment the further disposition of such securities by the transferee or assignee is restricted under the 1933 Act and applicable state securities laws; (iv) at or
before the time the Company receives the written notice contemplated by clause (ii) of this sentence the transferee or assignee agrees in writing with the Company to be bound by all of the provisions contained herein; and (v) such transfer
shall have been made in accordance with the applicable requirements of the Securities Purchase Agreement. Notwithstanding the foregoing, without the consent of the Company, the Investor may not assign its rights under this Agreement to a Competitor
of the Company. 
 10. Amendment of Registration Rights. 
 Provisions of this Agreement may be amended and the observance thereof may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the
Company and the Required Holders. Any amendment or waiver effected in accordance with this Section 10 shall be binding upon each Investor and the Company. No such amendment shall be effective to the extent that it applies to less than all of
the holders of the Registrable Securities. No consideration shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of any of this Agreement unless the same consideration also is offered to all of the
parties to this Agreement. 
 11. Miscellaneous. 
 a. A Person is deemed to be a holder of Registrable Securities whenever such Person owns or is deemed to own of record such Registrable Securities. If the Company receives conflicting instructions, notices or
elections from two or more Persons with respect to the same Registrable Securities, the Company shall act upon the basis of instructions, notice or election received from the such record owner of such Registrable Securities. 
 b. Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Agreement must be in writing and
will be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii) upon receipt, when sent by facsimile (provided confirmation of transmission is mechanically or electronically generated and kept on file by the
sending party); or (iii) one Business Day after deposit with a nationally recognized overnight delivery service, in each case properly addressed to the party to receive the same. The addresses and facsimile numbers for such communications shall

 Re: DayStar Technologies, Inc. 
 Ladies and
Gentlemen: 
 [We are][I am] counsel to DayStar Technologies, Inc., a Delaware corporation (the “Company”), and have
represented the Company in connection with that certain Registration Rights Agreement with the Holder (the “Registration Rights Agreement”) pursuant to which the Company agreed, among other things, to register the Registrable
Securities (as defined in the Registration Rights Agreement), including the shares of Common Stock issuable upon exercise of the Warrants, under the Securities Act of 1933, as amended (the “1933 Act”). In connection with the
Company’s obligations under the Registration Rights Agreement, on ____________ ___, 200_, the Company filed a Registration Statement on Form S-3 (File No. 333-_____________) (the “Registration Statement”) with the
Securities and Exchange Commission (the “SEC”) relating to the Registrable Securities which names each of the Holders as a selling shareholder thereunder. 
 In connection with the foregoing, [we][I] advise you that a member of the SEC’s staff has advised [us][me] by telephone that the SEC has entered an
order declaring the Registration Statement effective under the 1933 Act at [ENTER TIME OF EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and [we][I] have no knowledge, after telephonic inquiry of a member of the
SEC’s staff, that any stop order suspending its effectiveness has been issued or that any proceedings for that purpose are pending before, or threatened by, the SEC and the Registrable Securities are available for resale under the 1933 Act
pursuant to the Registration Statement. 
 This letter shall serve as our notice to you that the shares of Common Stock registered pursuant
to the Registration Statement are currently freely transferable by the Holders pursuant to the Registration Statement.

 SELLING SHAREHOLDERS 
 The shares of Common Stock being offered by the selling shareholders
are issuable upon exercise of the warrants. For additional information regarding the issuance of those warrants, see “Issuance of Warrants” above. We are registering the shares of Common Stock in order to permit the selling shareholders to
offer the shares for resale from time to time. Except for the ownership of convertible notes and warrants issued pursuant to the Securities Purchase Agreement, the selling shareholders have not had any material relationship with us within the past
three years. 
 The table below lists the selling shareholders and other information regarding the beneficial ownership of the shares of
Common Stock by each of the selling shareholders. The second column lists the number of shares of Common Stock beneficially owned by each selling shareholder, based on its ownership of warrants, as of
                , 200  , assuming exercise of the warrants held by the selling shareholders on that date, without regard to any limitations on
exercise. 
 The third column lists the shares of Common Stock being offered by this prospectus by the selling shareholders. 
 In accordance with the terms of registration rights agreements with the selling shareholders, this prospectus generally covers the resale of at least the
number of shares of Common Stock issued and issuable upon exercise of the warrants as of the trading day immediately preceding the date the registration statement is initially filed with the SEC. Because the exercise price of the warrants may be
adjusted, the number of shares that will actually be issued may be more or less than the number of shares being offered by this prospectus. The fourth column assumes the sale of all of the shares offered by the selling shareholders pursuant to this
prospectus. 
 Under the terms of the warrants, a selling shareholder may not exercise the warrants to the extent such exercise would cause
such selling shareholder, together with its affiliates, to beneficially own a number of shares of Common Stock which would exceed 4.99% of our then outstanding shares of Common Stock following such exercise, excluding for purposes of such
determination shares of Common Stock issuable upon exercise of the warrants which have not been exercised. The number of shares in the second column does not reflect this limitation. The selling shareholders may sell all, some or none of their
shares in this offering. See “Plan of Distribution.”

 PLAN OF DISTRIBUTION 
 We are registering the shares of Common Stock issuable upon exercise of the warrants to permit the resale of these shares of Common Stock by the holders of the warrants from time to time after the date of this
prospectus. We will not receive any of the proceeds from the sale by the selling shareholders of the shares of Common Stock. We will bear all fees and expenses incident to our obligation to register the shares of Common Stock. 
 The selling shareholders may sell all or a portion of the shares of Common Stock beneficially owned by them and offered hereby from time to time directly
or through one or more underwriters, broker-dealers or agents. If the shares of Common Stock are sold through underwriters or broker-dealers, the selling shareholders will be responsible for underwriting discounts or commissions or agent’s
commissions. The shares of Common Stock may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. These sales may be
effected in transactions, which may involve crosses or block transactions, 
  

	 	•	 	on any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale; 

  

	 	•	 	in the over-the-counter market; 

  

	 	•	 	in transactions otherwise than on these exchanges or systems or in the over-the-counter market; 

  

	 	•	 	through the writing of options, whether such options are listed on an options exchange or otherwise; 

  

	 	•	 	ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers; 

  

	 	•	 	block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

  

	 	•	 	purchases by a broker-dealer as principal and resale by the broker-dealer for its account; 

  

	 	•	 	an exchange distribution in accordance with the rules of the applicable exchange; 

  

	 	•	 	privately negotiated transactions; 

  

	 	•	 	short sales; 

  

	 	•	 	sales pursuant to Rule 144; 

  

	 	•	 	broker-dealers may agree with the selling security holders to sell a specified number of such shares at a stipulated price per share; 

	 	•	 	a combination of any such methods of sale; and 

  

	 	•	 	any other method permitted pursuant to applicable law. 

 If the selling shareholders effect such transactions by selling shares of Common Stock to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts,
concessions or commissions from the selling shareholders or commissions from purchasers of the shares of Common Stock for whom they may act as agent or to whom they may sell as principal (which discounts, concessions or commissions as to particular
underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved). In connection with sales of the shares of Common Stock or otherwise, the selling shareholders may enter into hedging transactions with
broker-dealers, which may in turn engage in short sales of the shares of Common Stock in the course of hedging in positions they assume. The selling shareholders may also sell shares of Common Stock short and deliver shares of Common Stock covered
by this prospectus to close out short positions and to return borrowed shares in connection with such short sales. The selling shareholders may also loan or pledge shares of Common Stock to broker-dealers that in turn may sell such shares.

 The selling shareholders may pledge or grant a security interest in some or all of the warrants or shares of Common Stock owned by them
and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of Common Stock from time to time pursuant to this prospectus or any amendment to this prospectus under Rule
424(b)(3) or other applicable provision of the Securities Act of 1933, amending, if necessary, the list of selling shareholders to include the pledgee, transferee or other successors in interest as selling shareholders under this prospectus. The
selling shareholders also may transfer and donate the shares of Common Stock in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this
prospectus. 
 The selling shareholders and any broker-dealer participating in the distribution of the shares of Common Stock may be deemed
to be “underwriters” within the meaning of the Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts under the Securities Act.
At the time a particular offering of the shares of Common Stock is made, a prospectus supplement, if required, will be distributed which will set forth the aggregate amount of shares of Common Stock being offered and the terms of the offering,
including the name or names of any broker-dealers or agents, any discounts, commissions and other terms constituting compensation from the selling shareholders and any discounts, commissions or concessions allowed or reallowed or paid to
broker-dealers. 
 Under the securities laws of some states, the shares of Common Stock may be sold in such states only through registered or
licensed brokers or dealers. In addition, in some states the shares of Common Stock may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is
complied with. 

 There can be no assurance that any selling shareholder will sell any or all of the shares of Common Stock
registered pursuant to the shelf registration statement, of which this prospectus forms a part. 
 The selling shareholders and any other
person participating in such distribution will be subject to applicable provisions of the Securities Exchange Act of 1934, and the rules and regulations thereunder, including, without limitation, Regulation M of the Securities Exchange Act of 1934,
which may limit the timing of purchases and sales of any of the shares of Common Stock by the selling shareholders and any other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of the shares
of Common Stock to engage in market-making activities with respect to the shares of Common Stock. All of the foregoing may affect the marketability of the shares of Common Stock and the ability of any person to engage in market-making activities
with respect to the shares of Common Stock. 
 We will pay all expenses of the registration of the shares of Common Stock pursuant to the
registration rights agreement, estimated to be $[            ] in total, including, without limitation, Securities and Exchange Commission filing fees and expenses of
compliance with state securities or “blue sky” laws; provided, however, that a selling shareholder will pay all underwriting discounts and selling commissions, if any. We will indemnify the selling shareholders against liabilities,
including some liabilities under the Securities Act, in accordance with the registration rights agreement, or the selling shareholders will be entitled to contribution. We may be indemnified by the selling shareholders against civil liabilities,
including liabilities under the Securities Act, that may arise from any written information furnished to us by the selling shareholder specifically for use in this prospectus, in accordance with the related registration rights agreement, or we may
be entitled to contribution. 
 Once sold under the shelf registration statement, of which this prospectus forms a part, the shares of Common
Stock will be freely tradable in the hands of persons other than our affiliates.
