(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 an initial Registration Statement on Form S-3 covering the resale of all of the Registrable Securities; provided that such
initial Registration Statement shall register for resale at least the number of shares of Common Stock equal to the Required Registration
Amount as of the date such Registration Statement is initially filed with the SEC; provided further that if Form S-3 is unavailable
for such a registration, the Company shall use such other form as is required by Section 2(c). Such initial Registration Statement,
and each other Registration Statement required to be filed pursuant to the terms of this Agreement, shall contain (except if otherwise
directed by the Required Holders) the “Selling Stockholders” and “Plan of Distribution” sections
in substantially the form attached hereto as Exhibit B. The Company shall use its reasonable best efforts to have such initial
Registration Statement, and each other Registration Statement required to be filed pursuant to the terms of this Agreement, declared
effective by the SEC as soon as practicable, but in no event later than the applicable Effectiveness Deadline for such Registration
Statement.


 




    	 	 3	 



     


    

 


(b)          Legal
Counsel. Subject to Section 5 hereof, Kelley Drye & Warren LLP, counsel solely to the lead investor (“Legal
Counsel”) shall review and oversee any registration, solely on behalf of the lead investor, pursuant to this Section 2.
Notwithstanding anything herein to the contrary, the Company shall have no obligations hereunder with respect to any other legal
counsel to any other Investor unless such other Investor delivers written notice to the Company with the name and contact information
of such other legal counsel representing such other Investor.


 


(c)          Ineligibility
to Use Form S-3. In the event that Form S-3 is not available for the registration of the resale of Registrable Securities by
the Investors, the Company shall (i) register the resale of the Registrable Securities on Form S-1 or another appropriate form
reasonably acceptable to the Required Holders and (ii) undertake to register the resale of the Registrable Securities on Form S-3
as soon as such form is available, provided that the Company shall maintain the effectiveness of all Registration Statements then
in effect until such time as a Registration Statement on Form S-3 covering the resale of all the Registrable Securities has been
declared effective by the SEC and the prospectus contained therein is available for use.


 


(d)          Sufficient
Number of Shares Registered. Subject to Section 2(f), in the event the number of shares available under any Registration Statement
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(h), the Company shall amend such Registration Statement
(if permissible), or file with the SEC 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 (but taking account of any Staff position with respect to the date on which the Staff
will permit such amendment to the Registration Statement and/or such new Registration Statement (as the case may be) to be filed
with the SEC). The Company shall use reasonable best efforts to cause such amendment to such Registration Statement and/or such
new Registration Statement (as the case may be) to become effective as soon as practicable following the filing thereof with the
SEC, but in no event later than the applicable Effectiveness Deadline for such Registration Statement. Subject to Section 2(f),
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 applicable 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 conversion, amortization and/or redemption of the Notes or exercise of the Warrants (and such calculation shall assume (A) that
the Notes are then convertible in full into shares of Common Stock at the then prevailing Conversion Rate (as defined in the Notes),
(B) the initial outstanding principal amount of the Notes remains outstanding through the scheduled Maturity Date (as defined in
the Notes) and no redemptions of the Notes occur prior to the scheduled Maturity Date and (C) the Warrants are then exercisable
in full into shares of Common Stock at the then prevailing Exercise Price (as defined in the Warrants)).


 




    	 	 4	 



     


    

 


(e)          Effect
of Failure to File and Obtain and Maintain Effectiveness of any Registration Statement. If (i) a Registration Statement covering
the resale of all of the Registrable Securities required to be covered thereby (after giving effect to any reduction pursuant to
Section 2(f)) and required to be filed by the Company pursuant to this Agreement is (A) not filed with the SEC on or before
the Filing Deadline for such Registration Statement (a “Filing Failure”) (it being understood that if the Company
files a Registration Statement without affording each Investor and Legal Counsel the opportunity to review and comment on the same
as required by Section 3(c) hereof, the Company shall be deemed to not have satisfied this clause (i)(A) and such event
shall be deemed to be a Filing Failure) or (B) not declared effective by the SEC on or before the Effectiveness Deadline for such
Registration Statement (an “Effectiveness Failure”) (it being understood that if on the Business Day immediately
following the Effective Date for such Registration Statement the Company shall not have filed a “final” prospectus
for such Registration Statement with the SEC under Rule 424(b) in accordance with Section 3(b) (whether or not such a prospectus
is technically required by such rule), the Company shall be deemed to not have satisfied this clause (i)(B) and such event shall
be deemed to be an Effectiveness Failure), (ii) other than during an Allowable Grace Period (as defined below), on any day after
the Effective Date of a Registration Statement sales of all of the Registrable Securities required to be included on such Registration
Statement (after giving effect to any reduction pursuant to Section 2(f)) cannot be made pursuant to such Registration Statement
(including, without limitation, because of a failure to keep such Registration Statement effective, a failure to disclose such
information as is necessary for sales to be made pursuant to such Registration Statement, a suspension or delisting of (or a failure
to timely list) the shares of Common Stock on the Principal Market (as defined in the Securities Purchase Agreement) or any other
limitations imposed by the Principal Market (other than the Stockholder Approval (as defined in the Securities Purchase Agreement)),
or a failure to register a sufficient number of shares of Common Stock under the terms of this Agreement or by reason of a stop
order) or the prospectus contained therein is not available for use for any reason (a “Maintenance Failure”),
or (iii) if a Registration Statement is not effective for any reason or the prospectus contained therein is not available for use
for any reason, and either (x) the Company fails for any reason to satisfy the requirements of Rule 144(c)(1), including, without
limitation, the failure to satisfy the current public information requirement under Rule 144(c) or (y) the Company has ever been
an issuer described in Rule 144(i)(1)(i) or becomes such an issuer in the future, and the Company shall fail to satisfy any condition
set forth in Rule 144(i)(2) (a “Current Public Information Failure”) as a result of which any of the Investors
are unable to sell Registrable Securities without restriction under Rule 144 (including, without limitation, volume restrictions),
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, including,
without limitation, specific performance), the Company shall pay to each holder of Registrable Securities relating to such Registration
Statement an amount in cash equal to one percent (1%) of the sum of such Investor’s aggregate original principal amount stated
in such Investor’s Series A Note and Series B Note on the Closing Date (1) on the date of such Filing Failure, Effectiveness
Failure, Maintenance Failure or Current Public Information Failure, as applicable, and (2) on every thirty (30) day anniversary
of (I) a Filing Failure until such Filing Failure is cured; (II) an Effectiveness Failure until such Effectiveness Failure is cured;
(III) a Maintenance Failure until such Maintenance Failure is cured; and (IV) a Current Public Information Failure until the
earlier of (i) the date such Current Public Information Failure is cured and (ii) such time that such public information is no
longer required pursuant to Rule 144 (in each case, pro rated for periods totaling less than thirty (30) days). The payments
to which a holder of Registrable Securities shall be entitled pursuant to this Section 2(e) are referred to herein as “Registration
Delay Payments;” provided, however, no Registration Delay Payments shall be payalble to an Investor with respect to a
Filing Failure, and Effectiveness Failure, a Maintenance Failure or a Current Public Information Failure to the extent (x) such
Registration Delay Payments relate to Registrable Securities such Investor elects not to include in such Registration Statement,
or (y) such Investor fails to timely performs its obligations under this Agreement; provided, further, that, in the event of any
reduction in Registrable Securities required to be included in such Registration Statement pursuant to Section 2(f), the Company
shall not be obligated to make any Registration Delay Payments with respect to such reduced number of Registrable Securities as
a result therefor. Following the initial Registration Delay Payment for any particular event or failure (which shall be paid on
the date of such event or failure, as set forth above), without limiting the foregoing, if an event or failure giving rise to the
Registration Delay Payments is cured prior to any thirty (30) day anniversary of such event or failure, then such Registration
Delay Payment shall be made on the third (3rd) Business Day after such cure. In the event the Company fails to make
Registration Delay Payments in a timely manner in accordance with the foregoing, such Registration Delay Payments shall bear interest
at the rate of one percent (1%) per month (prorated for partial months) until paid in full. Notwithstanding the foregoing, no Registration
Delay Payments shall be owed to an Investor (other than with respect to a Maintenance Failure resulting from a suspension or delisting
of (or a failure to timely list) the shares of Common Stock on the Principal Market) with respect to any period during which all
of such Investor’s Registrable Securities may be sold by such Investor without restriction under Rule 144 (including, without
limitation, volume restrictions) and without the need for current public information required by Rule 144(c)(1) (or Rule 144(i)(2),
if applicable).


 




    	 	 5	 



     


    

 


(f)          Offering.
Notwithstanding anything to the contrary contained in this Agreement, in the event the staff of the SEC (the “Staff”)
or the SEC seeks to characterize any offering pursuant to a Registration Statement filed pursuant to this Agreement as constituting
an offering of securities by, or on behalf of, the Company, or in any other manner, such that the Staff or the SEC
do not permit such Registration Statement to become effective and used for resales in a manner that does not constitute such
an offering and that permits the continuous resale at the market by the Investors participating therein (or as otherwise
may be acceptable to each Investor) without being named therein as an “underwriter,” then the Company shall reduce
the number of shares to be included in such Registration Statement by all Investors until such time as the Staff and the SEC
shall so permit such Registration Statement to become effective as aforesaid. In making such reduction, the Company shall reduce
the number of shares to be included by all Investors on a pro rata basis (based upon the number of Registrable Securities otherwise
required to be included for each Investor) unless the inclusion of shares by a particular Investor or a particular set of Investors
are resulting in the Staff or the SEC’s “by or on behalf of the Company” offering position, in which event the
shares held by such Investor or set of Investors shall be the only shares subject to reduction (and if by a set of Investors on
a pro rata basis by such Investors or on such other basis as would result in the exclusion of the least number of shares by all
such Investors); provided, that, with respect to such pro rata portion allocated to any Investor, such Investor may elect the allocation
of such pro rata portion among the Registrable Securities of such Investor. In addition, in the event that the Staff or the SEC
requires any Investor seeking to sell securities under a Registration Statement filed pursuant to this Agreement to be
specifically identified as an “underwriter” in order to permit such Registration Statement to become effective, and
such Investor does not consent to being so named as an underwriter in such Registration Statement, then, in each such case,
the Company shall reduce the total number of Registrable Securities to be registered on behalf of such Investor, until
such time as the Staff or the SEC does not require such identification or until such Investor accepts such identification and the
manner thereof. Any reduction pursuant to this paragraph will first reduce all Registrable Securities other than those issued
pursuant to the Securities Purchase Agreement. In the event of any reduction in Registrable Securities pursuant to this
paragraph, an affected Investor shall have the right to require, upon delivery of a written request to the Company signed
by such Investor, the Company to file a registration statement within twenty (20) days of such request (subject to any restrictions
imposed by Rule 415 or required by the Staff or the SEC) for resale by such Investor in a manner acceptable to such Investor,
and the Company shall following such request cause to be and keep effective such Registration Statement in the same manner
as otherwise contemplated in this Agreement for Registration Statements hereunder, in each case until such time as: (i) all
Registrable Securities held by such Investor have been registered and sold pursuant to an effective Registration Statement
in a manner acceptable to such Investor or (ii) all Registrable Securities may be resold by such Investor without restriction
(including, without limitation, volume limitations) pursuant to Rule 144 (taking account of any Staff position with respect to
“affiliate” status) and without the need for current public information required by Rule 144(c)(1) (or Rule 144(i)(2),
if applicable) or (iii) such Investor agrees to be named as an underwriter in any such Registration Statement in a manner acceptable
to such Investor as to all Registrable Securities held by such Investor and that have not theretofore been included in a Registration
Statement under this Agreement (it being understood that the special demand right under this sentence may be exercised by an Investor
multiple times and with respect to limited amounts of Registrable Securities in order to permit the resale thereof by such Investor
as contemplated above).


 




    	 	 6	 



     


    

 


(g)          Piggyback
Registrations. Without limiting any obligation of the Company hereunder or under the Securities Purchase Agreement, if there
is not an effective Registration Statement covering all of the Registrable Securities or the prospectus contained therein is not
available for use and the Company shall determine to prepare and file with the SEC a registration statement or offering statement
relating to an offering for its own account or the account of others under the 1933 Act of any of its equity securities (other
than on Form S-4 or Form S-8 (each as promulgated under the 1933 Act) or their then equivalents relating to equity securities to
be issued solely in connection with any acquisition of any entity or business or a business combination subject to Rule 145 under
the 1933 Act, or equity securities issuable in connection with the Company’s stock option or other employee benefit plans,
or any dividend or distribution reinvestment or similar plan), then the Company shall deliver to each Investor a written notice
of such determination and, if within fifteen (15) days after the date of the delivery of such notice, any such Investor shall
so request in writing, the Company shall include in such registration statement or offering statement all or any part of such Registrable
Securities such Investor requests to be registered; provided, however, the Company shall not be required to register any Registrable
Securities pursuant to this Section 2(g) that are eligible for resale pursuant to Rule 144 without restriction (including,
without limitation, volume restrictions) and without the need for current public information required by Rule 144(c)(1) (or Rule 144(i)(2),
if applicable) or that are the subject of a then-effective Registration Statement. The Company may postpone or withdraw the filing
or the effectiveness of a piggyback registration at any time in its sole discretion.


 


(h)          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 such 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 or assignee (as the case may be) that becomes an Investor shall
be allocated a pro rata portion of the then-remaining number of Registrable Securities included in such Registration Statement
for such transferor or assignee (as the case may be). 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.


 


(i)          No
Inclusion of Other Securities. The Company shall in no event include any securities other than Registrable Securities on any
Registration Statement filed in accordance herewith without the prior written consent of the Required Holders. Until the Applicable
Date (as defined in the Securities Purchase Agreement), the Company shall not enter into any agreement providing any registration
rights to any of its security holders, except as otherwise permitted under the Securities Purchase Agreement.


 


3.          Related
Obligations.


 


The Company shall use
reasonable 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:


 




    	 	 7	 



     


    

 


(a)          The
Company shall promptly prepare and file with the SEC a Registration Statement with respect to all the Registrable Securities (but
in no event later than the applicable Filing Deadline) and use reasonable best efforts to cause such Registration Statement to
become effective as soon as practicable after such filing (but in no event later than the Effectiveness Deadline). Subject to Allowable
Grace Periods, the Company shall keep each Registration Statement effective (and the prospectus contained therein available for
use) pursuant to Rule 415 for resales by the Investors on a delayed or continuous basis at then-prevailing market prices (and not
fixed prices) at all times until the earlier of (i) the date as of which all of the Investors may sell all of the Registrable Securities
required to be covered by such Registration Statement (disregarding any reduction pursuant to Section 2(f)) without restriction
pursuant to Rule 144 (including, without limitation, volume restrictions) and without the need for current public information required
by Rule 144(c)(1) (or Rule 144(i)(2), if applicable) or (ii) the date on which the Investors shall have sold all of the Registrable
Securities covered by such Registration Statement (the “Registration Period”). Notwithstanding anything to the
contrary contained in this Agreement, the Company shall ensure that, when filed and at all times while effective, each Registration
Statement (including, without limitation, all amendments and supplements thereto) and the prospectus (including, without limitation,
all amendments and supplements thereto) used in connection with such Registration Statement (1) 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 and (2) will disclose (whether
directly or through incorporation by reference to other SEC filings to the extent permitted) all material information regarding
the Company and its securities. The Company shall submit to the SEC, within one (1) Business Day 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 or that the Staff has no
further comments on a particular Registration Statement (as the case may be) and (ii) the consent of Legal Counsel is obtained
pursuant to Section 3(c) (which consent shall be immediately sought), a request for acceleration of effectiveness of such
Registration Statement to a time and date not later than forty-eight (48) hours after the submission of such request. The Company
shall respond in writing to comments made by the SEC in respect of a Registration Statement as soon as practicable, but in no event
later than fifteen (15) Business Days after the receipt of comments by or notice from the SEC that an amendment is required in
order for a Registration Statement to be declared effective.


 


(b)          Subject
to Section 3(r) of this Agreement, the Company shall prepare and file with the SEC such amendments (including, without limitation,
post-effective amendments) and supplements to each Registration Statement and the prospectus used in connection with each such
Registration Statement, which prospectus is to be filed pursuant to Rule 424 promulgated under the 1933 Act, as may be necessary
to keep each such Registration Statement effective at all times during the Registration Period for such Registration Statement,
and, during such period, comply with the provisions of the 1933 Act with respect to the disposition of all Registrable Securities
of the Company required to be 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 or the completion of the Registration Period; provided, however, by 8:30 a.m. (New York time) on the Business
Day immediately following each Effective Date, the Company shall file with the SEC in accordance with Rule 424(b) under the 1933
Act the final prospectus to be used in connection with sales pursuant to the applicable Registration Statement (whether or not
such a prospectus is technically required by such rule). In the case of amendments and supplements to any Registration Statement
which are required to be filed pursuant to this Agreement (including, without limitation, pursuant to this Section 3(b)) by
reason of the Company filing a report on Form 8-K, Form 10-Q or Form 10-K or any analogous report under the Securities Exchange
Act of 1934, as amended (the “1934 Act”), the Company shall, if permitted under the applicable rules and regulations
of the SEC, 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.


 




    	 	 8	 



     


    

 


(c)          The
Company shall (A) permit Legal Counsel and legal counsel for each other Investor to review and comment upon (i) each Registration
Statement at least five (5) Business Days prior to its filing with the SEC and (ii) all amendments and supplements to each Registration
Statement (including, without limitation, the prospectus contained therein) (except for Annual Reports on Form 10-K, Quarterly
Reports on Form 10-Q, Current Reports on Form 8-K, and any similar or successor reports) (collectively, the “Excluded
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 (other than Excluded Reports) in a form to which Legal Counsel or any legal counsel for any
other Investor reasonably objects; provided, however, that the Company shall not have any obligation to modify any information
if the Company reasonably expects that so doing would cause (i) the Registration Statement to contain an untrue statement of a
material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not
misleading or (ii) the prospectus contained therein to contain an untrue statement of a material fact or to omit to state a material
fact necessary in order to make the statements made, in light of the circumstances under which they were made, not misleading.
The Company shall not submit a request for acceleration of the effectiveness of a Registration Statement or any amendment or supplement
thereto or to any prospectus contained therein without the prior consent of Legal Counsel, which consent shall not be unreasonably
withheld, conditioned or delayed. The Company shall promptly furnish to Legal Counsel and legal counsel for each other Investor,
without charge, (i) copies of any correspondence from the SEC or the Staff to the Company or its representatives relating to each
Registration Statement, provided that such correspondence shall not contain any material, non-public information regarding the
Company or any of its Subsidiaries (as defined in the Securities Purchase Agreement), (ii) after the same is prepared and
filed with the SEC, one (1) copy of each Registration Statement and any amendment(s) and supplement(s) thereto, including, without
limitation, financial statements and schedules, all documents incorporated therein by reference, if requested by an Investor, and
all exhibits, in each case, unless publicly available on EDGAR, and (iii) upon the effectiveness of each Registration Statement,
one (1) copy of the prospectus included in such Registration Statement and all amendments and supplements thereto, unless publicly
available on EDGAR. The Company shall reasonably cooperate with Legal Counsel and legal counsel for each other Investor in performing
the Company’s obligations pursuant to this Section 3.


 


(d)          The
Company shall promptly furnish to each Investor whose Registrable Securities are included in any Registration Statement, without

and supplement(s) thereto, including, without limitation, financial statements and schedules, all documents incorporated therein
by reference, if requested by an Investor, all exhibits and each preliminary prospectus, in each case, unless publicly available
on EDGAR, (ii) upon the effectiveness of each Registration Statement, ten (10) copies of the prospectus included in such Registration

(e)          The
Company shall use its reasonable 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, without limitation, 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, 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, legal counsel for each other Investor 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 actual notice of the initiation or threatening of any proceeding for such purpose.


 


(f)          The
Company shall notify Legal Counsel, legal counsel for each other Investor 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, may include 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, non-public information regarding the Company
or any of its Subsidiaries), and, subject to Section 3(r), promptly prepare a supplement or amendment to such Registration
Statement and such prospectus contained therein to correct such untrue statement or omission and deliver ten (10) copies of such
supplement or amendment to Legal Counsel, legal counsel for each other Investor and each Investor (or such other number of copies
as Legal Counsel, legal counsel for each other Investor or such Investor may reasonably request). The Company shall also promptly
notify Legal Counsel, legal counsel for each other Investor and each Investor in writing (i) when a prospectus or any prospectus
supplement or post-effective amendment has been filed, when a Registration Statement or any post-effective amendment has become
effective (notification of such effectiveness shall be delivered to Legal Counsel, legal counsel for each other Investor and each
Investor by facsimile or e-mail on the same day of such effectiveness and by overnight mail), and when the Company receives written
notice from the SEC that a Registration Statement or any post-effective amendment will be reviewed by the SEC, (ii) of any request
by the SEC for amendments or supplements to a Registration Statement or related prospectus or related information, (iii) of the
Company’s reasonable determination that a post-effective amendment to a Registration Statement would be appropriate; and
(iv) of the receipt of any request by the SEC or any other federal or state governmental authority for any additional information
relating to the Registration Statement or any amendment or supplement thereto or any related prospectus. The Company shall respond
as promptly as practicable to any comments received from the SEC with respect to each Registration Statement or any amendment thereto
(it being understood and agreed that the Company’s response to any such comments shall be delivered to the SEC no later than
fifteen (15) Business Days after the receipt thereof).


 




    	 	 10	 



     


    

 


(g)          The
Company shall (i) use reasonable best efforts to prevent the issuance of any stop order or other suspension of effectiveness of
each Registration Statement or the use of any prospectus contained therein, or the suspension of the qualification, or the loss
of an exemption from 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 (ii) notify Legal
Counsel, legal counsel for each other Investor and each Investor who holds Registrable Securities of the issuance of such order
and the resolution thereof or its receipt of actual notice of the initiation or threat of any proceeding for such purpose.


 


(h)          If
any Investor may be required under applicable securities law to be described in any Registration Statement as an underwriter and
such Investor consents to so being named an underwriter, at the request of any Investor, the Company shall furnish to such Investor,
on the date of the effectiveness of such 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)          If
any Investor may be required under applicable securities law to be described in any Registration Statement as an underwriter and
such Investor consents to so being named an underwriter, upon the written request of such Investor, the Company shall make available
for inspection, upon reasonable notice and during normal business hours, by (i) such Investor, (ii) legal counsel for such Investor
and (iii) one (1) firm of accountants or other agents retained by such Investor (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 reasonably necessary by each Inspector to enable such Investor to exercise its due diligence responsibly,
and cause the Company’s officers, directors and employees to supply all information which any Inspector may reasonably request;
provided, however, each Inspector shall agree in writing to hold in strict confidence and not to make any disclosure (except to
such Investor) or use of any Record or other information which the Company’s board of directors determines in good faith
to be confidential, and of which determination the Inspectors are so notified, unless (1) the disclosure of such Records is necessary
to avoid or correct a misstatement or omission in any Registration Statement or is otherwise required under the 1933 Act, (2) 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 (3) the information in such Records has been made generally available to the public other than by disclosure in
violation of this Agreement or any other Transaction Document (as defined in the Securities Purchase Agreement). Such 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 such Investor, if any) shall be deemed to limit any Investor’s ability
to sell Registrable Securities in a manner which is otherwise consistent with applicable laws and regulations. For the avoidance
of doubt, any material non-public information received by an Inspector and/or an Investor in connection with exercising its inspection
right under this Section 3(i) shall not constitute a violation of any provision of the other Transaction Documents.


 




    	 	 11	 



     


    

 


(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 or is otherwise required to be disclosed
in such Registration Statement pursuant to the 1933 Act, (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 Transaction Document.
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 such Investor’s expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective
order for, such information.


 


(k)          Without
limiting any obligation of the Company under the Securities Purchase Agreement, the Company shall use reasonable best efforts either
to (i) cause all of the Registrable Securities covered by each Registration Statement to be listed on each securities exchange
on which securities of the same class or series issued by the Company are then listed, if any, if the listing of such Registrable
Securities is then permitted under the rules of such exchange, (ii) secure designation and quotation of all of the Registrable
Securities covered by each Registration Statement on an Eligible Market (as defined in the Securities Purchase Agreement), or (iii)
if, despite the Company’s reasonable best efforts to satisfy the preceding clauses (i) or (ii) the Company is unsuccessful
in satisfying the preceding clauses (i) or (ii), without limiting the generality of the foregoing, to use reasonable best to arrange
for at least two market makers to register with the Financial Industry Regulatory Authority (“FINRA”) as such
with respect to such Registrable Securities. In addition, the Company shall cooperate with each Investor and any broker or dealer
through which any such Investor proposes to sell its Registrable Securities in effecting a filing with FINRA pursuant to FINRA
Rule 5110 as requested by such Investor. The Company shall pay all fees and expenses in connection with satisfying its obligations
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 an effective Registration Statement and enable such certificates to be in such denominations or amounts
(as the case may be) as the Investors may reasonably request from time to time and registered in such names as the Investors may
request.


 


(m)          If
requested by an Investor, the Company shall as soon as practicable after receipt of notice from such Investor and subject to Section 3(r)
hereof, (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 or prospectus contained therein
if reasonably requested by an Investor holding any Registrable Securities.


 




    	 	 12	 



     


    

 


(n)          The
Company shall use reasonable best efforts to cause the Registrable Securities covered by a 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 applicable Effective Date of each Registration Statement.


 


(p)          The
Company shall otherwise use reasonable best efforts to comply with all applicable rules and regulations of the SEC in connection
with any registration hereunder.


 


(q)          Within
one (1) Business Day after a Registration Statement which covers Registrable Securities is declared 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 herein (but subject to the last sentence of this Section 3(r)), at any time after the Effective Date
of a particular Registration Statement, the Company may delay the disclosure of material, non-public information concerning the
Company or any of its Subsidiaries the disclosure of which at the time is not, in the good faith opinion of the board of directors
of the Company, 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 notify the Investors in writing of the (i) existence of material,
non-public information giving rise to a Grace Period (provided that in each such notice the Company shall not disclose the content
of such material, non-public information to any of the Investors) and the date on which such Grace Period will begin and (ii) date
on which such Grace Period ends, provided further that (I) no Grace Period shall exceed ten (10) consecutive days and during any
three hundred sixty five (365) day period all such Grace Periods shall not exceed an aggregate of thirty (30) days, (II) the first
day of any Grace Period must be at least five (5) Trading Days after the last day of any prior Grace Period and (III) no Grace
Period may exist during the sixty (60) Trading Day period immediately following the Effective Date of such Registration Statement
(provided that such sixty (60) Trading Day period shall be extended by the number of Trading Days during such period and any extension
thereof contemplated by this proviso during which such Registration Statement is not effective or the prospectus contained therein
is not available for use) (each, an “Allowable Grace Period”). For purposes of determining the length of a Grace
Period above, such Grace Period shall begin on and include the date the Investors receive the notice referred to in clause (i)
above and shall end on and include the later of the date the Investors receive the notice referred to in clause (ii) above 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 each 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 in this Section 3(r), 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 such Investor has entered into a contract for sale, and delivered
a copy of the prospectus included as part of the particular Registration Statement to the extent applicable, prior to such Investor’s
receipt of the notice of a Grace Period and for which the Investor has not yet settled.


 




    	 	 13	 



     


    

 


(s)          The
Company shall take all other reasonable actions necessary to expedite and facilitate disposition by each Investors of its Registrable
Securities pursuant to each Registration Statement.


 


(t)          Neither
the Company nor any Subsidiary or affiliate thereof shall identify any Investor as an underwriter in any public disclosure or filing
with the SEC, the Principal Market or any Eligible Market and any Buyer being deemed an underwriter by the SEC shall not relieve
the Company of any obligations it has under this Agreement or any other Transaction Document (as defined in the Securities Purchase
Agreement); provided, however, that the foregoing shall not prohibit the Company from including the disclosure found in the "Plan
of Distribution" section attached hereto as Exhibit B in the Registration Statement.


 


(u)          Neither
the Company nor any of its Subsidiaries has entered, as of the date hereof, nor shall the Company or any of its Subsidiaries, on
or after the date of this Agreement, enter into any agreement with respect to its securities, that would have the effect of impairing
the rights granted to the Buyers in this Agreement or otherwise conflicts with the provisions hereof.


 


4.          Obligations
of the Investors.


 


(a)          At
least five (5) Business Days prior to the first anticipated filing date of each Registration Statement, the Company shall notify
each Investor in writing of the information the Company requires from each such Investor with respect to 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 each 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.


 




    	 	 14	 



     


    

 


(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 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 in this Section 4(c), 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 such 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 such Investor has not yet settled.


 


5.          Expenses
of Registration.


 


All reasonable expenses,
other than underwriting discounts and commissions and stock transfer taxes, and fees and disbursements of legal counsel to any
Investor not subject to reimbursement under this Section 5 or any other Transaction Document, 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, FINRA filing fees (if any) and fees and disbursements of counsel for the Company shall be paid
by the Company. Notwithstanding the foregoing, the Company shall reimburse Legal Counsel for its fees and disbursements in connection
with registration, filing or qualification pursuant to Sections 2 and 3 of this Agreement which amount shall be limited to
$10,000 for each such registration, filing or qualification.


 


6.          Indemnification.


 


(a)          To
the fullest extent permitted by law, the Company will, and hereby does, indemnify, hold harmless and defend each Investor and each
of its directors, officers, shareholders, members, partners, employees, agents, advisors, representatives (and any other Persons
with a functionally equivalent role of a Person holding such titles notwithstanding the lack of such title or any other title)
and each Person, if any, who controls such Investor within the meaning of the 1933 Act or the 1934 Act and each of the directors,
officers, shareholders, members, partners, employees, agents, advisors, representatives (and any other Persons with a functionally
equivalent role of a Person holding such titles notwithstanding the lack of such title or any other title) of such controlling
Persons (each, an “Indemnified Person”), against any losses, obligations, claims, damages, liabilities, contingencies,
judgments, fines, penalties, charges, costs (including, without limitation, court costs, reasonable attorneys’ fees and costs
of defense and investigation), 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 or (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 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 such 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); and (ii) 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 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 any of the Registrable Securities by any of the Investors
pursuant to Section 9.


 



    	 	 15	 



     


    

 


(b)          In
connection with any Registration Statement in which an Investor is participating, 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, and the Company’s legal counsel named under the heading “Legal
Matters” in such Registration Statement (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) and the below provisos in this Section 6(b),
such Investor will reimburse an Indemnified Party any legal or other expenses reasonably incurred by such Indemnified Party in
connection with investigating or defending any such Claim; provided, however, 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 or delayed, provided further that such 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 applicable 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 any of the Registrable Securities by any of the
Investors pursuant to Section 9.


 


(c)          Promptly
after receipt by an Indemnified Person or Indemnified Party (as the case may be) under this Section 6 of notice of the commencement
of any action or proceeding (including, without limitation, any governmental action or proceeding) involving a Claim, such Indemnified
Person or Indemnified Party (as the case may be) 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, an Indemnified Person or Indemnified
Party (as the case may be) shall have the right to retain its own counsel with the fees and expenses of such counsel to be paid
by the indemnifying party if: (i) the indemnifying party has agreed in writing to pay such fees and expenses; (ii) the indemnifying
party shall have failed promptly to assume the defense of such Claim and to employ counsel reasonably satisfactory to such Indemnified
Person or Indemnified Party (as the case may be) in any such Claim; or (iii) the named parties to any such Claim (including, without
limitation, any impleaded parties) include both such Indemnified Person or Indemnified Party (as the case may be) and the indemnifying
party, and such Indemnified Person or such Indemnified Party (as the case may be) shall have been advised by counsel that a conflict
of interest is likely to exist if the same counsel were to represent such Indemnified Person or such Indemnified Party and the
indemnifying party (in which case, if such Indemnified Person or such Indemnified Party (as the case may be) notifies the indemnifying
party in writing that it elects to employ separate counsel at the expense of the indemnifying party, then the indemnifying party
shall not have the right to assume the defense thereof and such counsel shall be at the expense of the indemnifying party, provided
further that in the case of clause (iii) above the indemnifying party shall not be responsible for the reasonable fees and expenses
of more than one (1) separate legal counsel for such Indemnified Person or Indemnified Party (as the case may be). The Indemnified
Party or Indemnified Person (as the case may be) shall reasonably cooperate 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 (as the case may be) which relates to such action or Claim.
The indemnifying party shall keep the Indemnified Party or Indemnified Person (as the case may be) reasonably 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, 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 (as the case may be), 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 (as the case may be) of a release from all liability in respect to such Claim or litigation, and such
settlement shall not include any admission as to fault on the part of the Indemnified Party. Following indemnification as provided
for hereunder, the indemnifying party shall be subrogated to all rights of the Indemnified Party or Indemnified Person (as the
case may be) 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 (as the case may
be) under this Section 6, except to the extent that the indemnifying party is materially and adversely prejudiced in its ability
to defend such action.


 




    	 	 16	 



     


    

 


(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 and contribution 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:
(i) no contribution shall be made under circumstances where the maker would not have been liable for indemnification under the
fault standards set forth in Section 6 of this Agreement, (ii) no Person involved in the sale of Registrable Securities which
Person 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 (iii) contribution by any seller of Registrable Securities shall be limited in amount to the amount
of net proceeds received by such seller from the applicable sale of such Registrable Securities pursuant to such Registration Statement.
Notwithstanding the provisions of this Section 7, no Investor shall be required to contribute, in the aggregate, any amount
in excess of the amount by which the net proceeds actually received by such Investor from the applicable sale of the Registrable
Securities subject to the Claim exceeds the amount of any damages that such Investor has otherwise been required to pay, or would
otherwise be required to pay under Section 6(b), by reason of such untrue or alleged untrue statement or omission or alleged
omission.

8.          Reports
Under the 1934 Act.


 


With a view to making
available to the Investors the benefits of 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, subject to any extension periods permitted by applicable SEC rules and regulations, 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 and agreed that nothing herein shall limit any obligations of the Company under 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, submission and posting 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
with the SEC if such reports are not publicly available via EDGAR, 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.


 


All or any portion
of the rights under this Agreement shall be automatically assignable by each Investor to any transferee or assignee (as the case
may be) of all or any portion of such Investor’s Registrable Securities, Notes or Warrants if: (i) such Investor agrees in
writing with such transferee or assignee (as the case may be) to assign all or any portion of such rights, and a copy of such agreement
is furnished to the Company within a reasonable time after such transfer or assignment (as the case may be); (ii) the Company is,
within a reasonable time after such transfer or assignment (as the case may be), furnished with written notice of (a) the name
and address of such transferee or assignee (as the case may be), and (b) the securities with respect to which such registration
rights are being transferred or assigned (as the case may be); (iii) immediately following such transfer or assignment (as
the case may be) the further disposition of such securities by such transferee or assignee (as the case may be) is restricted under
the 1933 Act or applicable state securities laws if so required; (iv) at or before the time the Company receives the written notice
contemplated by clause (ii) of this sentence such transferee or assignee (as the case may be) agrees in writing with the Company
to be bound by all of the provisions contained herein; (v) such transfer or assignment (as the case may be) shall have been made
in accordance with the applicable requirements of the Securities Purchase Agreement, the Notes and the Warrants (as the case may
be); and (vi) such transfer or assignment (as the case may be) shall have been conducted in accordance with all applicable federal
and state securities laws.

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; provided that any such amendment or waiver
that complies with the foregoing, but that disproportionately, materially and adversely affects the rights and obligations of any
Investor relative to the comparable rights and obligations of the other Investors shall require the prior written consent of such
adversely affected Investor. Any amendment or waiver effected in accordance with this Section 10 shall be binding upon each Investor
and the Company, provided that no such amendment shall be effective to the extent that it (1) applies to less than all of the holders
of Registrable Securities or (2) imposes any obligation or liability on any Investor without such Investor’s prior written
consent (which may be granted or withheld in such Investor’s sole discretion). No waiver shall be effective unless it is
in writing and signed by an authorized representative of the waiving party. No consideration shall be offered or paid to any Person
to amend or consent to a waiver or modification of any provision of this Agreement unless the same consideration (other than the
reimbursement of legal fees) also is offered to all of the parties to this Agreement.


 


11.         Miscellaneous.


 


(a)         Solely
for purposes of this Agreement, 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 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 electronic mail (provided that such sent email is kept on file (whether electronically or otherwise) by the sending party
and the sending party does not receive an automatically generated message from the recipient's email server that such e-mail could
not be delivered to such recipient); or (iii) one (1) Business Day after deposit with a nationally recognized overnight delivery
service with next day delivery specified, in each case, properly addressed to the party to receive the same. The addresses, facsimile
numbers and email addresses for such communications shall be:

(c)         Failure
of any party to exercise any right or remedy under this Agreement or otherwise, or delay by a party in exercising such right or
remedy, shall not operate as a waiver thereof. The Company and each Investor acknowledge and agree that irreparable damage would
occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were
otherwise breached. It is accordingly agreed that each party hereto shall be entitled to an injunction or injunctions to prevent
or cure breaches of the provisions of this Agreement by any other party hereto and to enforce specifically the terms and provisions
hereof (without the necessity of showing economic loss and without any bond or other security being required), this being in addition
to any other remedy to which any party may be entitled by law or equity.


 




    	 	 20	 



     


    

 


(d)         All
questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the internal
laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the
State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the
State of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting
in The City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with
any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action
or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding
is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Each party hereby irrevocably
waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy
thereof to such party at the address for such notices to it under this Agreement and agrees that such service shall constitute
good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right
to serve process in any manner permitted by law. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO, AND AGREES NOT
TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION HEREWITH OR ARISING OUT OF THIS AGREEMENT
OR ANY TRANSACTION CONTEMPLATED HEREBY.


 


(e)         If
any provision of this Agreement is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent
jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the
broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect
the validity of the remaining provisions of this Agreement so long as this Agreement as so modified continues to express, without
material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or
unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations
of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will
endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s),
the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).


 


(f)          This
Agreement, the other Transaction Documents, the schedules and exhibits attached hereto and thereto and the instruments referenced
herein and therein constitute the entire agreement among the parties hereto and thereto solely with respect to the subject matter
hereof and thereof. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to
herein and therein. This Agreement, the other Transaction Documents, the schedules and exhibits attached hereto and thereto and
the instruments referenced herein and therein supersede all prior agreements and understandings among the parties hereto solely
with respect to the subject matter hereof and thereof; provided, however, nothing contained in this Agreement or any other Transaction
Document shall (or shall be deemed to) (i) have any effect on any agreements any Investor has entered into with the Company or
any of its Subsidiaries prior to the date hereof with respect to any prior investment made by such Investor in the Company, (ii)
waive, alter, modify or amend in any respect any obligations of the Company or any of its Subsidiaries or any rights of or benefits
to any Investor or any other Person in any agreement entered into prior to the date hereof between or among the Company and/or
any of its Subsidiaries and any Investor and all such agreements shall continue in full force and effect or (iii) limit any obligations
of the Company under any of the other Transaction Documents.


 




    	 	 21	 



     


    

 


(g)         Subject
to compliance with Section 9 (if applicable), this Agreement shall inure to the benefit of and be binding upon the permitted
successors and assigns of each of the parties hereto. This Agreement is not for the benefit of, nor may any provision hereof be
enforced by, any Person, other than the parties hereto, their respective permitted successors and assigns and the Persons referred
to in Sections 6 and 7 hereof.


 


(h)         The
headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof. Unless
the context clearly indicates otherwise, each pronoun herein shall be deemed to include the masculine, feminine, neuter, singular
and plural forms thereof. The terms “including,” “includes,” “include” and words of like import
shall be construed broadly as if followed by the words “without limitation.” The terms “herein,” “hereunder,”
“hereof” and words of like import refer to this entire Agreement instead of just the provision in which they are found.


 


(i)          This
Agreement may be executed in two or more identical counterparts, each of which shall be deemed an original, but all of which shall
be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered
to the other party. In the event that any signature is delivered by facsimile transmission or by an email which contains a portable
document format (.pdf) file of an executed signature page, such signature page shall create a valid and binding obligation of the
party executing (or on whose behalf such signature is executed) with the same force and effect as if such signature page were an
original thereof.


 


(j)          Each
party shall do and perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver
all such other agreements, certificates, instruments and documents as any other party may reasonably request in order to carry
out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby.


 


(k)         The
language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent and no rules
of strict construction will be applied against any party. Notwithstanding anything to the contrary set forth in Section 10, terms
used in this Agreement but defined in the other Transaction Documents shall have the meanings ascribed to such terms on the Closing
Date in such other Transaction Documents unless otherwise consented to in writing by each Investor.


 




    	 	 22	 



     


    

 


(l)          All
consents and other determinations required to be made by the Investors pursuant to this Agreement shall be made, unless otherwise
specified in this Agreement, by the Required Holders, determined as if all of the outstanding Notes then held by the Investors
have been converted for Registrable Securities without regard to any limitations on redemption, amortization and/or conversion
of the Notes and the outstanding Warrants then held by Investors have been exercised for Registrable Securities without regard
to any limitations on exercise of the Warrants.


 


(m)        This
Agreement is intended for the benefit of the parties hereto and their respective permitted successors and assigns, and is not for
the benefit of, nor may any provision hereof be enforced by, any other Person.


 


(n)         The
obligations of each Investor under this Agreement and the other Transaction Documents are several and not joint with the obligations
of any other Investor, and no Investor shall be responsible in any way for the performance of the obligations of any other Investor
under this Agreement or any other Transaction Document. Nothing contained herein or in any other Transaction Document, and no action
taken by any Investor pursuant hereto or thereto, shall be deemed to constitute the Investors as, and the Company acknowledges
that the Investors do not so constitute, a partnership, an association, a joint venture or any other kind of group or entity, or
create a presumption that the Investors are in any way acting in concert or as a group or entity with respect to such obligations
or the transactions contemplated by the Transaction Documents or any matters, and the Company acknowledges that the Investors are
not acting in concert or as a group, and the Company shall not assert any such claim, with respect to such obligations or the transactions
contemplated by this Agreement or any of the other the Transaction Documents. Each Investor shall be entitled to independently
protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of any other Transaction
Documents, and it shall not be necessary for any other Investor to be joined as an additional party in any proceeding for such
purpose. The use of a single agreement with respect to the obligations of the Company contained herein was solely in the control
of the Company, not the action or decision of any Investor, and was done solely for the convenience of the Company and not because
it was required or requested to do so by any Investor. It is expressly understood and agreed that each provision contained in this
Agreement and in each other Transaction Document is between the Company and an Investor, solely, and not between the Company and
the Investors collectively and not between and among Investors.

Ladies and Gentlemen:


 


We have represented
Real Goods Solar, Inc., a Colorado corporation (the “Company”), in connection with the Securities Purchase Agreement
(the “SPA”), dated as of March 30, 2018, as amended, by and among the Company and the investors who are parties thereto
(collectively, the “Holders”), pursuant to which the Company issued to the Holders (i) senior convertible notes (the
“Unsecured Notes”), which are convertible into shares of the Company’s Class A Common Stock, par value $0.0001
per share (the “Common Stock”), (ii) senior secured convertible notes (together with the Unsecured Notes, collectively,
the “Notes”), which are convertible into shares of the Common Stock, and (iii) Series Q Warrants to purchase shares
of the Common Stock (the “Warrants”).


 


On ____________ ___,
20__, the Company filed a Registration Statement on Form S-_ (File No. 333-_____________) (the “Registration Statement”)
with the Securities and Exchange Commission (the “SEC”) pursuant to the Securities Act of 1933, as amended (the “1933
Act”) relating to the shares of the Common Stock issuable upon [conversion of the Notes (the “Conversion Shares”)][exercise
of the Warrants (the “Warrant Shares”)][conversion of the Notes (the “Conversion Shares”) and exercise
of the Warrants (together with the Conversion Shares, collectively, the “Shares”)] which names the Holders as selling
shareholders thereunder.


 


In connection with
the foregoing, we advise you that the Registration Statement is effective with the SEC pursuant to the 1933 Act, and we have no
knowledge 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 [Conversion Shares][Warrant Shares][Shares] are available for issuance and sale under
the 1933 Act pursuant to the Registration Statement.


 


This letter shall serve
as our instruction to you that the [Conversion Shares][Warrant Shares][Shares] are freely transferable by the Holders pursuant
to the Registration Statement.

EXHIBIT B


 


SELLING STOCKHOLDERS


 


The shares of common
stock being offered by the selling stockholders are those issuable to the selling stockholders upon conversion of the notes and
exercise of the warrants. For additional information regarding the issuance of the notes and the warrants, see “Private Placement
of Notes and Warrants” above. We are registering the shares of common stock in order to permit the selling stockholders to
offer the shares for resale from time to time. Except for the ownership of the notes and the warrants issued pursuant to the Securities
Purchase Agreement or as described in the table below, the selling stockholders have not had any material relationship with us
within the past three years.


 


The table below lists
the selling stockholders and other information regarding the beneficial ownership (as determined under Section 13(d) of the Securities
Exchange Act of 1934, as amended, and the rules and regulations thereunder) of the shares of common stock held by each of the selling
stockholders. The second column lists the number of shares of common stock beneficially owned by the selling stockholders, based
on their respective ownership of shares of common stock, notes and warrants, as of ________, 2018, assuming conversion of the notes
and exercise of the warrants held by each such selling stockholder on that date but taking account of any limitations on conversion
and exercise set forth therein.


 


The third column lists
the shares of common stock being offered by this prospectus by the selling stockholders and does not take in account any limitations
on (i) conversion of the notes set forth therein or (ii) exercise of the warrants set forth therein.


 


In accordance with
the terms of a registration rights agreement with the holders of the notes and the warrants, this prospectus generally covers the
resale of 200% of the sum of (i) the maximum number of shares of common stock issued or issuable pursuant to the Series A Notes,
and (ii) the maximum number of shares of common stock issued or issuable upon exercise of the warrants, in each case, determined
as if the outstanding notes and warrants were converted or exercised (as the case may be) in full (without regard to any limitations
on conversion or exercise contained therein solely for the purpose of such calculation) at the alternate conversion price or exercise
price (as the case may be) calculated as of the trading day immediately preceding the date this registration statement was initially
filed with the SEC. Because the conversion price of the 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 stockholders pursuant to this prospectus.


 


Under the terms of
the notes and the warrants, a selling stockholder may not convert the notes or exercise the warrants to the extent (but only to
the extent) such selling stockholder or any of its affiliates would beneficially own a number of shares of our common stock which
would exceed 9.99% of the outstanding shares of the Company. The number of shares in the second column reflects these limitations.
The selling stockholders 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 notes and exercise of the warrants to permit the resale of these shares
of common stock by the holders of the 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 stockholders of the shares of common stock, although we will receive the exercise
price of any Warrants not exercised by the selling stockholders on a cashless exercise basis. We will bear all fees and expenses
incident to our obligation to register the shares of common stock.


 


The selling stockholders
may sell all or a portion of the shares of common stock held 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 stockholders 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, pursuant to one or more of the following methods:


 


		·	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 or settlement 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 made after the date the Registration Statement is declared effective by the SEC;



 


		·	broker-dealers may agree with a selling security holder 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.



 




     


     


    

 


The selling stockholders
may also sell shares of common stock under Rule 144 promulgated under the Securities Act of 1933, as amended, if available,
rather than under this prospectus. In addition, the selling stockholders may transfer the shares of common stock by other means
not described in this prospectus. If the selling stockholders 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 stockholders 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 stockholders 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
stockholders 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 stockholders may also loan or
pledge shares of common stock to broker-dealers that in turn may sell such shares.


 


The selling stockholders
may pledge or grant a security interest in some or all of the notes, 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 amending, if necessary, the list of selling stockholders to include the pledgee, transferee or
other successors in interest as selling stockholders under this prospectus. The selling stockholders 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.


 


To the extent required
by the Securities Act and the rules and regulations thereunder, the selling stockholders 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 stockholders and any discounts, commissions or concessions allowed or re-allowed
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 stockholder will sell any or all of the shares of common stock registered pursuant to the registration statement,
of which this prospectus forms a part.


 


The selling stockholders
and any other person participating in such distribution will be subject to applicable provisions of the Securities Exchange Act
of 1934, as amended, and the rules and regulations thereunder, including, without limitation, to the extent applicable, Regulation M
of the Exchange Act, which may limit the timing of purchases and sales of any of the shares of common stock by the selling stockholders
and any other participating person. To the extent applicable, 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 or entity 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, a selling stockholder will pay all underwriting discounts and selling commissions,
if any. We will indemnify the selling stockholders against liabilities, including some liabilities under the Securities Act in
accordance with the registration rights agreements or the selling stockholders will be entitled to contribution. We may be indemnified
by the selling stockholders against civil liabilities, including liabilities under the Securities Act that may arise from any written
information furnished to us by the selling stockholder specifically for use in this prospectus, in accordance with the related
registration rights agreements or we may be entitled to contribution.


 


Once sold under the
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.
