 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, 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 

  

 3 

 
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. Except for (i) up to 200,000 shares of Common Stock issuable upon exercise of outstanding warrants issued to consultants of the
Company and (ii) the shares of Common Stock issuable upon exercise of the warrants issued to Ardour Capital in connection with the transactions contemplated by the Transaction Documents, in no event shall the Company include any 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 conversion or redemption of the Note or the exercise of the Warrants and such calculation shall assume that the Note is then convertible into shares of Common Stock at the then prevailing Conversion Rate (as defined in the Note)
and that the Warrants are then exercisable for shares of Common Stock at the then prevailing Exercise Price (as defined in the Warrants). 
  

 4 

 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 each holder of Registrable Securities relating to such Registration Statement an amount in cash equal to two percent (2.0%) of the outstanding principal
amount of the Note of such Investor’s Registrable Securities included in such Registration Statement on each of the following dates: (i) the day of a Filing Failure and 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 in an amount equal to two percent (2%) of the outstanding principal amount of the Note of such Investor’s Registrable Securities included in such Registration Statement on the third Business Day after such
120th day. 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 10% of the average total amount
of the Notes outstanding in any 12 month period. 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 

  

 5 

 
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 

  

 6 

 
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 

  

 7 

 
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 

  

 8 

 
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. 
  

 9 

 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. 
  

 11 

 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 

  

 12 

 
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 

  

 13 

 
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 

  

 14 

 
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 

  

 15 

 
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 be:

	 	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 Securities Purchase Agreement (the “Securities Purchase Agreement”) entered into by and among the Company and the buyer named therein (collectively, the “Holder”) pursuant to which the
Company issued to the Holder a convertible note (the “Note”) convertible into the Company’s common stock, $0.01 par value per share (the “Common Stock”), and warrants exercisable for shares of Common Stock (the
“Warrants”). Pursuant to the Securities Purchase Agreement, the Company also has entered into a 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 conversion of the Note, and as interest on the Note and 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.

 EXHIBIT B 
 SELLING SHAREHOLDERS 
 The shares of Common Stock being offered by the selling shareholders are
issuable upon conversion of the convertible notes and upon exercise of the warrants. For additional information regarding the issuance of those convertible notes and warrants, see “Private Placement of Shares of Convertible Notes “ 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 the 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 the convertible notes and warrants, as of ________, 200_, assuming conversion of all convertible notes and exercise of the warrants held by the selling shareholders on that date, without regard to any
limitations on conversions or 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 130% of the sum of (i) the number of shares of Common Stock issued and issuable upon conversion of the convertible notes (and the interest accrued and payable thereunder) as of the trading day immediately preceding
the date the registration statement is initially filed with the SEC and (ii) the number of shares of Common Stock issued and issuable upon exercise of the related warrants as of the trading day immediately preceding the date the registration
statement is initially filed with the SEC. Because the conversion price of the convertible notes and 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 convertible notes and the warrants, a selling shareholder may not convert the convertible notes or exercise the warrants to the extent such conversion or 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 conversion or exercise, excluding for purposes of such
determination shares of Common Stock issuable upon conversion of the convertible notes which have not been converted and 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 conversion of the convertible notes and upon exercise of the warrants to permit the resale of these shares of Common Stock by the holders of the convertible
notes and 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 convertible notes or 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.

 3. Obligations and Liabilities of the Escrow Agent.

 (b) The Escrow Agent shall not be responsible in any manner whatsoever for any failure or inability of any other Party to perform or comply with any of the provisions of this Agreement.

question as to the construction hereof or any action to be taken or omitted to be taken by the Escrow Agent, the Escrow Agent shall be entitled to consult with counsel of its own choosing. The Escrow Agent shall incur no liability or responsibility

appointed by the Investor and the Company within thirty (30) days after notice of the resignation of the Escrow Agent, the Escrow Agent may petition a court of competent jurisdiction to name a successor escrow agent hereunder. The Escrow Agent
shall be fully relieved of all liability under this Agreement except for its willful misconduct or gross negligence upon the appointment of the successor escrow agent and the transfer of the Escrowed Funds to the successor Escrow Agent

designated by the Investor and the Company or appointed by such court of competent jurisdiction, as the case may be.
