(b)           Notwithstanding
anything to the contrary set forth in this Section 2, in the event the Commission does not permit the Company to register all

of Registrable Securities to be registered on such Registration Statement will be reduced in the order of the Registrable Securities
represented by the total number of Purchased Shares owned by the Holders, applied on a pro rata basis. The Company shall use its
commercially reasonable efforts to file additional Registration Statements to register the Registrable Securities that were not
registered in the initial Registration Statement and are not saleable under Rule 144 without limitation as promptly as possible
but in no event later than on the Filing Date and in a manner permitted by the Commission. For purposes of this Section 2(b),

Statement or any subsequent Registration Statement and (ii) six (6) months following the effective date of the initial Registration
Statement or any subsequent Registration Statement, as applicable, or such earlier date as permitted by the Commission. For purposes
of this Section 2(b), “Effectiveness Date” means with respect to each subsequent Registration Statement filed
pursuant hereto, the earlier of (A) the ninetieth (90th) day following the filing date of such Registration Statement
(or in the event such Registration Statement receives a “full review” by the Commission, the one hundred twentieth
(120th) day following such filing date) or (B) the date which is within three (3) Business Days after the date on which
the Commission informs the Company (i) that the Commission will not review such Registration Statement or (ii) that the
Company may request the acceleration of the effectiveness of such Registration Statement; provided that, if the
Effectiveness Date falls on a Saturday, Sunday or any other day which shall be a legal holiday or a day on which the Commission
is authorized or required by law or other government actions to close, the Effectiveness Date shall be the following Business
Day.


 


(c)           Each
Holder agrees to furnish to the Company a completed Selling Stockholder Questionnaire not more than ten (10) Business Days following
the date of this Agreement. Each Holder further agrees that it shall not be entitled to be named as a selling security holder
in the Registration Statement or use the Prospectus for offers and resales of Registrable Securities at any time, unless such
Holder has returned to the Company a completed and signed Selling Stockholder Questionnaire. If a Holder of Registrable Securities
returns a Selling Stockholder Questionnaire after the deadline specified in the previous sentence, the Company shall use its commercially
reasonable efforts to take such actions as are required to name such Holder as a selling security holder in the Registration Statement
or any pre-effective or post-effective amendment thereto and to include (to the extent not theretofore included) in the Registration
Statement the Registrable Securities identified in such late Selling Stockholder Questionnaire; provided that the Company
shall not be required to file an additional Registration Statement solely for such shares. Each Holder acknowledges and agrees
that the information in the Selling Stockholder Questionnaire will be used by the Company in the preparation of the Registration
Statement and hereby consents to the inclusion of such information in the Registration Statement.

or Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or
that requires any revisions to the Registration Statement, Prospectus or other documents so that, in the case of the Registration
Statement or the Prospectus, as the case may be, it will not contain any 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 (in the case of the Prospectus, in
the light of the circumstances under which they were made) not misleading.


 


(d)           Use
its commercially reasonable efforts to avoid the issuance of, or, if issued, obtain the withdrawal of, as promptly as possible,
(i) any order suspending the effectiveness of the Registration Statement or (ii) any suspension of the qualification (or exemption
from qualification) of any of the Registrable Securities for sale in any jurisdiction.

selling Holders in connection with the registration or qualification (or exemption from such registration or qualification) of
such Registrable Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions within the United States
as any Holder requests in writing, to keep each such registration or qualification (or exemption therefrom) effective during the
Effectiveness Period and to do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions
of the Registrable Securities covered by a Registration Statement; provided, however, that the Company shall not
be required to qualify generally to do business in any jurisdiction where it is not then so qualified or to take any action that

and registered in such names of the Holder in connection with any sale of Registrable Securities.


 


(j)           Upon
the occurrence of any event contemplated by Section 3(c)(iv), as promptly as possible, prepare a supplement or amendment, including
a post-effective amendment, to the Registration Statement or a supplement to the related Prospectus or any document incorporated
or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, neither
the Registration Statement nor such Prospectus will contain an 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 the Prospectus, in the light of
the circumstances under which they were made) not misleading.


 


(k)           Use
its commercially reasonable efforts to cause all Registrable Securities relating to the Registration Statement, to continue to

beneficially owned by such Holder and the natural persons thereof that have voting and dispositive control over the Registrable
Securities. During any periods that the Company is unable to meet its obligations hereunder with respect to the registration of
the Registrable Securities solely because any Holder fails to furnish such information within five (5) Business Days of the Company’s
request, any liquidated damages that are accruing at such time as to such Holder only shall be tolled and any Event that may otherwise
occur solely because of such delay shall be suspended as to such Holder only, until such information is delivered to the Company.

thereto, or arising out of or based upon any omission of a material fact required to be stated therein or necessary to make the
statements therein (in the case of any Prospectus or form of prospectus or supplement thereto, in the light of the circumstances
under which they were made) not misleading, to the extent, but only to the extent, that such untrue statement or omission is contained
in any information so furnished in writing by such Holder or other Indemnifying Party to the Company specifically for inclusion
in the Registration Statement or such Prospectus. Notwithstanding anything to the contrary contained herein, each Holder shall
be liable under this Section 5(b) only for the lesser of (a) the actual damages incurred or (b) that amount as does not exceed
the gross proceeds to such Holder as a result of the sale of his/her/its Registrable Securities pursuant to such Registration
Statement.


 


(c)           Conduct
of Indemnification Proceedings. If any Proceeding shall be brought or asserted against any Person entitled to indemnity hereunder
(an “Indemnified Party”), such Indemnified Party promptly shall promptly notify the Person from whom indemnity
is sought (the “Indemnifying Party”) in writing, and the Indemnifying Party shall be entitled to assume the
defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees
and expenses incurred in connection with defense thereof; provided that the failure of any Indemnified Party to give such notice
shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the
extent that it shall be finally determined by a court of competent jurisdiction (which determination is not subject to appeal
or further review) that such failure shall have proximately and materially adversely prejudiced the Indemnifying Party.


 


An
Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof,
but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (1) the Indemnifying
Party has agreed in writing to pay such fees and expenses; or (2) the Indemnifying Party shall have failed promptly to assume
the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding;
or (3) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the
Indemnifying Party, and such parties shall have been advised by counsel that a conflict of interest is likely to exist if the
same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if such Indemnified Party notifies
the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, 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).
The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld or delayed. No Indemnifying Party shall, without the prior written consent of the Indemnified
Party, effect any settlement of any pending or threatened Proceeding in respect of which any Indemnified Party is a party and
indemnity has been sought hereunder, unless such settlement includes an unconditional release of such Indemnified Party from all
liability on claims that are the subject matter of such Proceeding.

(d)           Contribution.
If a claim for indemnification under Section 5(a) or 5(b) is due but unavailable to an Indemnified Party because of a failure
or refusal of a governmental authority to enforce such indemnification in accordance with its terms (by reason of public policy
or otherwise), then each Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid
or payable by such Indemnified Party as a result of such Losses, in such proportion as is appropriate to reflect the relative
benefits received by the Indemnifying Party on the one hand and the Indemnified Party on the other from the offering of the Purchased
Shares. If, but only if, the allocation provided by the foregoing sentence is not permitted by applicable law, the allocation
of contribution shall be made in such proportion as is appropriate to reflect not only the relative benefits referred to in the
foregoing sentence but also the relative fault, as applicable, of the Indemnifying Party and Indemnified Party in connection with
the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The
relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether
any action in question, including any untrue statement of a material fact or omission of a material fact, has been taken or made
by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the parties’ relative
intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount
paid or payable by a party as a result of any Losses shall be deemed to include, subject to the limitations set forth in Section
5(c), any reasonable attorneys’ or other reasonable fees or expenses incurred by such party in connection with any Proceeding
to the extent such party would have been indemnified for such fees or expenses if the indemnification provided for in this Section
was available to such party in accordance with its terms. In no event shall any selling Holder be required to contribute an amount
under this Section 5(d) in excess of the gross proceeds received by such Holder upon sale of such Holder’s Registrable Securities
pursuant to the Registration Statement giving rise to such contribution obligation.


 


The
parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 5(d) were determined by
pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred
to in the immediately preceding paragraph. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f)
of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.


 






    	 	12	 



    


    

 


The
indemnity and contribution agreements contained in this Section are in addition to any liability that the Indemnifying Parties
may have to the Indemnified Parties pursuant to applicable law.


 


6.           Rule
144.


Unless
and until such time as the Holder can sell the Registrable Securities pursuant to Rule 144, the Company covenants to timely file
(or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the
Company after the date hereof pursuant to Section 13(a) or 15(d) of the Exchange Act. As long as any Holder owns Warrants or Registrable
Securities, if the Company is not required to file reports pursuant to Section 13(a) or 15(d) of the Exchange Act, it will prepare
and furnish to the Holders and make publicly available in accordance with Rule 144(c) promulgated under the Securities Act, annual
and quarterly financial statements, together with a discussion and analysis of such financial statements in form and substance
substantially similar to those that would otherwise be required to be included in reports required by Section 13(a) or 15(d) of
the Exchange Act, as well as any other information required thereby, in the time period that such filings would have been required
to have been made under the Exchange Act. The Company further covenants that it will take such further action as any Holder may
reasonably request, all to the extent reasonably required from time to time to enable such Person to sell the Purchased Shares
without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the
Securities Act, including providing any legal opinions relating to such sale pursuant to Rule 144. Upon the request of any Holder,
the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with
such requirements.


 


7.           Miscellaneous.


 


(a)           Remedies.
In the event of a breach by the Company or by a Holder of any of their obligations under this Agreement, such Holder or the Company,
as the case may be, in addition to being entitled to exercise all rights granted by law and under this Agreement, including recovery
of damages, will be entitled to specific performance of its rights under this Agreement. Each of the Company and each Holder
agrees that monetary damages would not provide adequate compensation for any losses incurred by reason of a breach by it
of any of the provisions of this Agreement and hereby further agrees that, in the event of any action for specific performance
in respect of such breach, it shall waive the defense that a remedy at law would be adequate.


 


(b)           No
Inconsistent Agreements. Other than in connection with the Second Private Offering, the Company has not entered into, and
shall not enter into on or after the date of this Agreement, any agreement with respect to its securities that is inconsistent
with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. The Company has not
previously entered into any agreement that is currently in effect granting any registration rights with respect to any of its
securities to any Person, except as otherwise provided herein or as granted to the Placement Agent as defined under the Purchase
Agreement. Without limiting the generality of the foregoing and other than in connection with the Second Private Offering, without
the written consent of the Holders of a majority of the then outstanding Registrable Securities, the Company shall not grant to
any Person the right to request the Company to register any securities of the Company under the Securities Act unless the rights
so granted are subject in all respects to the prior rights in full of the Holders set forth herein, and are not otherwise in conflict
with the provisions of this Agreement.


 






    	 	13	 



    


    

 


(c)           No
Piggyback on Registrations for Other Securities. Neither the Company nor any of its security holders may include securities
of the Company in the Registration Statement, and the Company shall not after the date hereof enter into any agreement providing
such right to any of its security holders, unless the right so granted is subject in all respects to the prior rights in full
of the Holders set forth herein, and is not otherwise in conflict with the provisions of this Agreement.


 


(d)           Piggy-Back
Registrations for Registrable Securities. If at any time when there is not an effective Registration Statement covering the
Purchased Shares, the Company shall determine to prepare and file with the Commission a registration statement relating to an
offering for its own account or the account of others under the Securities Act of any of its equity securities, other than on
Form S-4 or Form S-8 (each as promulgated under the Securities Act) or their then equivalents relating to equity securities to
be issued solely in connection with any acquisition of any entity or business or equity securities issuable in connection with
stock option or other employee benefit plans, the Company shall send to each Holder of Registrable Securities written notice of
such determination and, if within ten (10) calendar days after receipt of such notice, or within such shorter period of time as
may be specified by the Company in such written notice as may be necessary for the Company to comply with its obligations with
respect to the timing of the filing of such registration statement, any such Holder shall so request in writing (which request
shall specify the Registrable Securities intended to be disposed of by the such Holder), the Company will cause the registration
under the Securities Act of all Registrable Securities which the Company has been so requested to register by the Holder, to the
extent requisite to permit the disposition of the Registrable Securities so to be registered, provided that if at any time after
giving written notice of its intention to register any securities and prior to the effective date of the registration statement
filed in connection with such registration, the Company shall determine for any reason not to register or to delay registration
of such securities, the Company may, at its election, give written notice of such determination to such Holder and, thereupon,
(i) in the case of a determination not to register, shall be relieved of its obligation to register any Registrable Securities
in connection with such registration (but not from its obligation to pay expenses in accordance with Section 4 hereof), and (ii)
in the case of a determination to delay registering, shall be permitted to delay registering any Registrable Securities being
registered pursuant to this Section 7(d) for the same period as the delay in registering such other securities. The Company shall
include in such registration statement all or any part of such Registrable Securities such Holder requests to be registered; provided,
however, that the Company shall not be required to register any Registrable Securities pursuant to this Section 7(d) that
are eligible for sale pursuant to Rule 144 of the Securities Act. In the case of an underwritten public offering, if the managing
underwriter(s) or underwriter(s) should reasonably object to the inclusion of the Registrable Securities in such registration
statement, then if the Company after consultation with the managing underwriter should reasonably determine that the inclusion
of such Registrable Securities would materially adversely affect the offering contemplated in such registration statement, and
based on such determination recommends inclusion in such registration statement of fewer or none of the Registrable Securities
of the Holders, then (x) the number of Registrable Securities of the Holders included in such registration statement shall be
reduced among such Holders based upon the number of Registrable Securities requested to be included in the registration
in the order set forth in Section 2(b) hereof, if the Company after consultation with the underwriter(s) recommends the inclusion
of fewer Registrable Securities, or (y) none of the Registrable Securities of the Holders shall be included in such registration
statement, if the Company after consultation with the underwriter(s) recommends the inclusion of none of such Registrable Securities;
provided, however, that if securities are being offered for the account of other persons or entities as well as
the Company, such reduction shall not represent a greater fraction of the number of Registrable Securities intended to be offered
by the Holders than the fraction of similar reductions imposed on such other persons or entities (other than the Company). For
purposes of this Section 7(d), Registrable Securities shall include any shares actually issued to the Purchasers pursuant to the
Securities Escrow Agreement.

(e)           Amendments
and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the same shall be in writing
and signed by the Company and the Holders of a majority of the then outstanding Registrable Securities.


 


(f)           Notices.
Unless otherwise provided herein, whenever notice is required to be given under this Agreement, such notice shall be given in
accordance with Section 7.9 of the Purchase Agreement.


(g)           Successors
and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted
assigns and shall inure to the benefit of each Holder and its successors and assigns. The Company may not assign this Agreement
or any of its rights or obligations hereunder without the prior written consent of each Holder. Each Purchaser may assign its
rights hereunder in the manner and to the Persons as permitted under the Purchase Agreement.


 


(h)           Assignment
of Registration Rights. The rights of each Holder hereunder, including the right to have the Company register for resale Registrable
Securities in accordance with the terms of this Agreement, shall be automatically assignable by each Holder to any Person who
acquires all or a portion of the Warrants or the Registrable Securities if: (i) the Holder agrees in writing with the transferee
or assignee to assign such rights, and a copy of such agreement is furnished to the Company within a reasonable time after such
assignment, (ii) the Company is, within a reasonable time after such transfer or assignment, furnished with written notice of
(a) the name and address of such transferee or assignee, and (b) the securities with respect to which such registration rights
are being transferred or assigned, (iii) following such transfer or assignment the further disposition of such securities by the
transferee or assignees is restricted under the Securities Act and applicable state securities laws unless such securities are
registered in a Registration Statement under this Agreement (in which case the Company shall be obligated to amend such Registration
Statement to reflect such transfer or assignment) or are otherwise exempt from registration, (iv) at or before the time the Company
receives the written notice contemplated by clause (ii) of this Section, the transferee or assignee agrees in writing with the
Company to be bound by all of the provisions of this Agreement, and (v) such transfer shall have been made in accordance with
the applicable requirements of the Purchase Agreement. The rights to assignment shall apply to the Holders (and to subsequent)
successors and assigns.


 






    	 	15	 



    


    

 


(i)           Counterparts.
This Agreement may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original
and, all of which taken together shall constitute one and the same Agreement and shall become effective when counterparts have
been signed by each party and delivered to the other parties hereto, it being understood that all parties need not sign the same
counterpart. In the event that any signature is delivered by facsimile transmission, such signature shall create a valid binding
obligation of the party executing (or on whose behalf such signature is executed) the same with the same force and effect as if
such facsimile signature were the original thereof.


(j)           Governing
Law; Jurisdiction. This Agreement shall be governed by and construed in accordance with the internal laws of the State of
New York, without giving effect to any of the conflicts of law principles which would result in the application of the substantive
law of another jurisdiction. This Agreement shall not be interpreted or construed with any presumption against the party causing
this Agreement to be drafted. The Company and the Holders agree that venue for any dispute arising under this Agreement will lie
exclusively in the state or federal courts located in New York, NY, and the parties irrevocably waive any right to raise forum
non conveniens or any other argument that New York, NY is not the proper venue. The Company and the Holders irrevocably consent
to personal jurisdiction in the state and federal courts of the state of New York. The Company and the Holders consent to process
being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address in effect for notices
to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof.
Nothing in this Section 7(j) shall affect or limit any right to serve process in any other manner permitted by law. The Company
and the Holders hereby agree that the prevailing party in any suit, action or proceeding arising out of or relating to this Agreement
or the Purchase Agreement, shall be entitled to reimbursement for reasonable legal fees from the non-prevailing party. The parties
hereby waive all rights to a trial by jury.


 


(k)           Cumulative
Remedies. The remedies provided herein are cumulative and not exclusive of any remedies provided by law.


 


(l)           Severability.
If any term, provision, covenant or restriction of this Agreement is held to be invalid, illegal, void or unenforceable in any
respect, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect
and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their reasonable efforts to find and
employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision,
covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed
the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid,
illegal, void or unenforceable.


 


(m)           Headings.
The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect
any of the provisions hereof.


 






    	 	16	 



    


    

 


(n)           Shares
Held by the Company and its Affiliates. Whenever the consent or approval of Holders of a specified percentage of Registrable
Securities is required hereunder, Registrable Securities held by the Company or its Affiliates (other than any Holder or transferees
or successors or assigns thereof if such Holder is deemed to be an Affiliate solely by reason of its holdings of such Registrable
Securities) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage.


 


(o)           Independent
Nature of Purchasers. The Company acknowledges that the obligations of each Purchaser under the Transaction Documents are
several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance
of the obligations of any other Purchaser under the Transaction Documents. The Company acknowledges that the decision of each
Purchaser to purchase Securities pursuant to the Purchase Agreement has been made by such Purchaser independently of any other
Purchaser and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets,
properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company or of its Subsidiaries
which may have been made or given by any other Purchaser or by any agent or employee of any other Purchaser, and no Purchaser
or any of its agents or employees shall have any liability to any Purchaser (or any other person) relating to or arising from
any such information, materials, statements or opinions. The Company acknowledges that nothing contained herein, or in any Transaction
Document, and no action taken by any Purchaser pursuant hereto or thereto (including, but not limited to, the (i) inclusion of
a Purchaser in the Registration Statement and (ii) review by, and consent to, such Registration Statement by a Purchaser) shall
be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create
a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions
contemplated by the Transaction Documents. The Company acknowledges that each Purchaser shall be entitled to independently protect
and enforce its rights, including without limitation, the rights arising out of this Agreement or out of the other Transaction
Documents, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such
purpose. The Company acknowledges that it has elected to provide all Purchasers with the same terms and Transaction Documents
for the convenience of the Company and not because it was required or requested to do so by the Purchasers. The Company acknowledges
that such procedure with respect to the Transaction Documents in no way creates a presumption that the Purchasers are in any way
acting in concert or as a group with respect to the Transaction Documents or the transactions contemplated hereby or thereby.

Exhibit
A


Plan
of Distribution


 


The
selling security holders and any of their pledgees, donees, assignees and successors-in-interest may, from time to time, sell
any or all of their shares of common stock being offered under this prospectus on any stock exchange, market or trading facility
on which shares of our common stock are traded or in private transactions. These sales may be at fixed or negotiated prices. The
selling security holders may use any one or more of the following methods when disposing of shares:


 


		●	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 resales by the broker-dealer for its account;
	 	 	 
		●	an
                                         exchange distribution in accordance with the rules of the applicable exchange;
	 	 	 
		●	privately
                                         negotiated transactions;
	 	 	 
		●	to
                                         cover short sales made after the date that the registration statement of which this prospectus
                                         is a part is declared effective by the Commission;
	 	 	 
		●	broker-dealers
                                         may agree with the selling security holders to sell a specified number of such shares
                                         at a stipulated price per share;
	 	 	 
		●	a
                                         combination of any of these methods of sale; and
	 	 	 
		●	any
                                         other method permitted pursuant to applicable law.



 


The
shares may also be sold under Rule 144 under the Securities Act of 1933, as amended (“Securities Act”), if available,
rather than under this prospectus. The selling security holders have the sole and absolute discretion not to accept any purchase
offer or make any sale of shares if they deem the purchase price to be unsatisfactory at any particular time.


 


The
selling security holders may pledge their shares to their brokers under the margin provisions of customer agreements. If a selling
security holder defaults on a margin loan, the broker may, from time to time, offer and sell the pledged shares.


 


Broker-dealers
engaged by the selling security holders may arrange for other broker-dealers to participate in sales. Broker-dealers may receive
commissions or discounts from the selling security holders (or, if any broker-dealer acts as agent for the purchaser of shares,
from the purchaser) in amounts to be negotiated, which commissions as to a particular broker or dealer may be in excess of customary
commissions to the extent permitted by applicable law.


 






     

    


    

 


If
sales of shares offered under this prospectus are made to broker-dealers as principals, we would be required to file a post-effective
amendment to the registration statement of which this prospectus is a part. In the post-effective amendment, we would be required
to disclose the names of any participating broker-dealers and the compensation arrangements relating to such sales.


 


The
selling security holders and any broker-dealers or agents that are involved in selling the shares offered under this prospectus
may be deemed to be “underwriters” within the meaning of the Securities Act in connection with these sales. Commissions
received by these broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting
commissions or discounts under the Securities Act. Any broker-dealers or agents that are deemed to be underwriters may not sell
shares offered under this prospectus unless and until we set forth the names of the underwriters and the material details of their
underwriting arrangements in a supplement to this prospectus or, if required, in a replacement prospectus included in a post-effective
amendment to the registration statement of which this prospectus is a part.


 


The
selling security holders and any other persons participating in the sale or distribution of the shares offered under this prospectus
will be subject to applicable provisions of the Exchange Act, and the rules and regulations under that act, including Regulation
M. These provisions may restrict activities of, and limit the timing of purchases and sales of any of the shares by, the selling
security holders or any other person. Furthermore, under Regulation M, persons engaged in a distribution of securities are prohibited
from simultaneously engaging in market making and other activities with respect to those securities for a specified period of
time prior to the commencement of such distributions, subject to specified exceptions or exemptions. All of these limitations
may affect the marketability of the shares.


 


If
any of the shares of common stock offered for sale pursuant to this prospectus are transferred other than pursuant to a sale under
this prospectus, then subsequent holders could not use this prospectus until a post-effective amendment or prospectus supplement
is filed, naming such holders. We offer no assurance as to whether any of the selling security holders will sell all or any portion
of the shares offered under this prospectus.


 


We
have agreed to pay all fees and expenses we incur incident to the registration of the shares being offered under this prospectus.
However, each selling security holder and purchaser is responsible for paying any discounts, commissions and similar selling expenses
they incur.


 


We
and the selling security holders have agreed to indemnify one another against certain losses, damages and liabilities arising
in connection with this prospectus, including liabilities under the Securities Act.


 






     

    


    

 


Exhibit
B


Selling
Stockholder Notice and Questionnaire


 


The
undersigned understands that Redwood Scientific Technologies, Inc. (the “Company”) intends to file with the
Securities and Exchange Commission a registration statement on Form S-1 (the “Resale Registration Statement”)
for the registration and the resale under Rule 415 of the Securities Act of 1933, as amended (the “Securities Act”),
of the Registrable Securities in accordance with the terms of the Registration Rights Agreement entered into by the Company and
the undersigned (the “Agreement”). All capitalized terms not otherwise defined herein shall have the meanings
ascribed thereto in the Agreement.


 


In
order to sell or otherwise dispose of any Registrable Securities pursuant to the Resale Registration Statement, a holder of Registrable
Securities generally will be required to be named as a selling stockholder in the related prospectus or a supplement thereto (as
so supplemented, the “Prospectus”), deliver the Prospectus to purchasers of Registrable Securities (including
pursuant to Rule 172 under the Securities Act) and be bound by the provisions of the Agreement (including certain indemnification
provisions, as described below). Holders must complete and deliver this Notice and Questionnaire in order to be named as selling

The
undersigned agrees to promptly notify the Company of any inaccuracies or changes in the information provided herein that may occur
subsequent to the date hereof and prior to the effective date of any applicable Resale Registration Statement. All notices hereunder
shall be made in writing, by hand delivery, confirmed or facsimile transmission, first-class mail or air courier guaranteeing
overnight delivery at the address set forth below. In the absence of any such notification, the Company shall be entitled to continue
to rely on the accuracy of the information in this Notice and Questionnaire.


 






     

    


    

 


By
signing below, the undersigned consents to the disclosure of the information contained herein in its answers to Items (1) through
(7) above and the inclusion of such information in the Resale Registration Statement and the Prospectus. The undersigned understands
that such information will be relied upon by the Company in connection with the preparation or amendment of any such Registration
Statement and the Prospectus.


 


By
signing below, the undersigned acknowledges that it understands its obligation to comply, and agrees that it will comply, with
the provisions of the Exchange Act and the rules and regulations thereunder, particularly Regulation M in connection with any
offering of Registrable Securities pursuant to the Resale Registration Statement. The undersigned also acknowledges that it understands
that the answers to this Questionnaire are furnished for use in connection with Registration Statements filed pursuant to the
Agreement and any amendments or supplements thereto filed with the Commission pursuant to the Securities Act.


 


The
undersigned hereby acknowledges and is advised of the following Interpretation A.65 of the July 1997 SEC Manual of Publicly Available
Telephone Interpretations regarding short selling:


 


“An
Issuer filed a Form S-3 registration statement for a secondary offering of common stock which is not yet effective. One of the
selling stockholders wanted to do a short sale of common stock “against the box” and cover the short sale with registered
shares after the effective date. The issuer was advised that the short sale could not be made before the registration statement
become effective, because the shares underlying the short sale are deemed to be sold at the time such sale is made. There would,
therefore, be a violation of Section 5 if the shares were effectively sold prior to the effective date.”


 


By
returning this Questionnaire, the undersigned will be deemed to be aware of the foregoing interpretation.


 


I
confirm that, to the best of my knowledge and belief, the foregoing statements (including without limitation the answers to this
Questionnaire) are correct.


 


IN
WITNESS WHEREOF the undersigned, by authority duly given, has caused this Questionnaire to be executed and delivered either in
person or by its duly authorized agent.
