2.
REGISTRATION.


 


a.
Mandatory Registration. The Company shall, within fifteen (15) calendar days from the filing date of the Company’s
annual report on Form 10-K for the fiscal year ended December 31, 2018 with the SEC, file with the SEC an initial Registration
Statement covering the maximum number of Registrable Securities (beginning with the Purchase Notice Shares) as shall be permitted
to be included thereon in accordance with applicable SEC rules, regulations and interpretations so as to permit the resale of
such Registrable Securities by the Investor, including but not limited to under Rule 415 under the Securities Act at then prevailing
market prices (and not fixed prices), as mutually determined by both the Company and the Investor in consultation with their respective
legal counsel, subject to the aggregate number of authorized shares of the Company’s Common Stock then available for issuance
in its Articles of Incorporation. The initial Registration Statement shall register only the Registrable Securities. The Investor
and its counsel shall have a reasonable opportunity (which, for purposes of this Agreement, shall be two (2) Trading Days) to
review and comment upon such Registration Statement and any amendment or supplement to such Registration Statement and any related
prospectus prior to its filing with the SEC, and the Company shall give due consideration to all reasonable comments. The Investor
shall furnish all information reasonably requested by the Company for inclusion therein. The Company shall use commercially reasonable
efforts to have the Registration Statement and any amendment declared effective by the SEC at the earliest possible date. The
Company shall use commercially reasonable efforts to keep the Registration Statement effective, including but not limited to pursuant
to Rule 415 promulgated under the Securities Act and available for the resale by the Investor of all of the Registrable Securities
covered thereby at all times until the earlier of (i) the date as of which the Investor may sell all of the Registrable Securities
without restriction pursuant to Rule 144 promulgated under the Securities Act and (ii) the date on which the Investor shall have
sold all the Registrable Securities covered thereby and no Purchase Notice Shares remain under the Purchase Agreement (the “Registration
Period”). The Registration Statement (including any amendments or supplements thereto and prospectuses contained therein)
shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary
to make the statements therein, in light of the circumstances in which they were made, not misleading.


 


b.
Rule 424 Prospectus. The Company shall, as required by applicable securities regulations, from time to time file with the
SEC, pursuant to Rule 424 promulgated under the Securities Act, the prospectus and prospectus supplements, if any, to be used
in connection with sales of the Registrable Securities under the Registration Statement. The Investor and its counsel shall have
a reasonable opportunity (which, for purposes of this Agreement, shall be two (2) Trading Days) to review and comment upon such
prospectus prior to its filing with the SEC, and the Company shall give due consideration to all such comments. The Investor shall
use its commercially reasonable efforts to comment upon such prospectus within one (1) Trading Day from the date the Investor
receives the final pre-filing version of such prospectus.


 


c.
Sufficient Number of Shares Registered. In the event the number of shares available under the Registration Statement is
insufficient to cover all of the Registrable Securities, the Company shall amend the Registration Statement or file a new Registration
Statement (a “New Registration Statement”), so as to cover all of such Registrable Securities (subject to the
limitations set forth in Section 2(a)) as soon as practicable, but in any event not later than ten (10) Trading Days after the
necessity therefor arises, subject to any limits that may be imposed by the SEC pursuant to Rule 415 under the Securities Act.
The Company shall use commercially reasonable efforts to cause such amendment and/or New Registration Statement to become effective
as soon as practicable following the filing thereof. Unless the Registration Period has ended, in the event that any of the Purchase
Notice Shares are not included in the Registration Statement, or have not been included in any New Registration Statement and
the Company files any other registration statement under the Securities Act (other than on Form S-4, Form S-8, or with respect
to other employee related plans or rights offerings) (“Other Registration Statement “) then the Company shall
include in such Other Registration Statement first all of such Purchase Notice Shares that have not been previously registered,
and second any other securities the Company wishes to include in such Other Registration Statement. Unless the Registration Period
has ended, the Company agrees that it shall not file any such Other Registration Statement unless all of the Purchase Notice Shares
have been included in such Other Registration Statement or otherwise have been registered for resale as described above.


 


d.
Offering. If 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 that does not permit such Registration
Statement to become effective and be used for resales by the Investor under Rule 415 at then-prevailing market prices (and not
fixed prices), or if after the filing of the initial Registration Statement with the SEC pursuant to Section 2(a), the Company
is otherwise required by the Staff or the SEC to reduce the number of Registrable Securities included in such initial Registration
Statement, then the Company shall reduce the number of Registrable Securities to be included in such initial Registration Statement
(with the prior consent, which shall not be unreasonably withheld, of the Investor and its legal counsel as to the specific Registrable
Securities to be removed therefrom) until such time as the Staff and the SEC shall so permit such Registration Statement to become
effective and be used as aforesaid. Unless the Registration Period has ended, in the event of any reduction in Registrable Securities
pursuant to this paragraph, the Company shall file one or more New Registration Statements in accordance with Section 2(c) until
such time as all Registrable Securities have been included in Registration Statements that have been declared effective and the
prospectus contained therein is available for use by the Investor. Notwithstanding any provision herein or in the Purchase Agreement
to the contrary, the Company’s obligations to register Registrable Securities (and any related conditions to the Investor’s
obligations) shall be qualified as necessary to comport with any requirement of the SEC or the Staff as addressed in this Section
2(d).


 




    	 



    	 



    

 


3.
RELATED OBLIGATIONS.


 


With
respect to the Registration Statement and whenever any Registrable Securities are to be registered pursuant to Section 2 including
on any New Registration Statement, the Company shall use commercially reasonable efforts to effect the registration of the Registrable
Securities in accordance with the intended method of disposition thereof and, pursuant thereto, the Company shall have the following
obligations:


 


a.
The Company shall prepare and file with the SEC such amendments (including post-effective amendments) and supplements to any registration
statement and the prospectus used in connection with such registration statement, which prospectus is to be filed pursuant to
Rule 424 promulgated under the Securities Act, as may be necessary to keep the Registration Statement or any New Registration
Statement effective at all times during the Registration Period, and, during such period, comply with the provisions of the Securities
Act with respect to the disposition of all Registrable Securities of the Company covered by the Registration Statement or any
New 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.


 


b.
The Company shall permit the Investor to review and comment upon the Registration Statement or any New Registration Statement
and all amendments and supplements thereto at least two (2) Trading Days prior to their filing with the SEC, and not file any
document in a form to which Investor reasonably objects. The Investor shall use commercially reasonable efforts to comment upon
the Registration Statement or any New Registration Statement and any amendments or supplements thereto within two (2) Trading
Days from the date the Investor receives the final version thereof. The Company shall furnish to the Investor, without charge
any correspondence from the SEC or the staff of the SEC to the Company or its representatives relating to the Registration Statement
or any New Registration Statement.


 


c.
Upon request of the Investor, the Company shall furnish to the Investor, (i) promptly after the same is prepared and filed with
the SEC, at least one copy of such registration statement and any amendment(s) thereto, including financial statements and schedules,
all documents incorporated therein by reference and all exhibits, (ii) upon the effectiveness of any registration statement, a
copy of the prospectus included in such registration statement and all amendments and supplements thereto (or such other number
of copies as the Investor may reasonably request) and (iii) such other documents, including copies of any preliminary or final
prospectus, as the Investor may reasonably request from time to time in order to facilitate the disposition of the Registrable
Securities owned by the Investor. For the avoidance of doubt, any filing available to the Investor via the SEC’s live EDGAR
system shall be deemed “furnished to the Investor” hereunder.


 


d.
The Company shall use commercially reasonable efforts to (i) register and qualify the Registrable Securities covered by a registration
statement under such other securities or “blue sky” laws of California, (ii) prepare and file in those jurisdictions,
such amendments (including post-effective amendments) and supplements to such registrations and qualifications as may be necessary
to maintain the effectiveness thereof during the Registration Period, (iii) take such other actions as may be necessary to maintain
such registrations and qualifications in effect at all times during the Registration Period, and (iv) take all other actions reasonably
necessary or advisable to qualify the Registrable Securities for sale in such jurisdictions; provided, however, that the Company
shall not be required in connection therewith or as a condition thereto to (x) qualify to do business in any jurisdiction where
it would not otherwise be required to qualify but for this Section 3(d), (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 the 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 California
or its receipt of actual notice of the initiation or threatening of any proceeding for such purpose.


 




    	 



    	 



    

 


e.
As promptly as practicable after becoming aware of such event or facts, the Company shall notify the Investor in writing of the
happening of any event or existence of such facts as a result of which the prospectus included in any registration statement,
as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and promptly
prepare a supplement or amendment to such registration statement to correct such untrue statement or omission, and deliver a copy
of such supplement or amendment to the Investor (or such other number of copies as the Investor may reasonably request). The Company
shall also promptly notify the Investor in writing (i) when a prospectus or any prospectus supplement or post-effective amendment
has been filed, and when a registration statement or any post-effective amendment has become effective (notification of such effectiveness
shall be delivered to the Investor by email or facsimile on the same day of such effectiveness and by overnight mail), (ii) of
any request by the SEC for amendments or supplements to any registration statement or related prospectus or related information,
and (iii) of the Company’s reasonable determination that a post-effective amendment to a registration statement would be
appropriate.


 


f.
The Company shall use commercially reasonable efforts to prevent the issuance of any stop order or other suspension of effectiveness
of any registration statement, or the suspension of the qualification of any Registrable Securities for sale in any jurisdiction
and, if such an order or suspension is issued, to obtain the withdrawal of such order or suspension at the earliest possible moment
and to notify the Investor 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.


 


g.
The Company shall (i) cause all the Registrable Securities 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, or (ii) secure designation and quotation of all the Registrable Securities on the Principal
Market. The Company shall pay all fees and expenses in connection with satisfying its obligation under this Section.


 


h.
The Company shall cooperate with the Investor to facilitate the timely preparation and delivery of certificates (not bearing any
restrictive legend) representing the Registrable Securities to be offered pursuant to any registration statement and enable such
certificates to be in such denominations or amounts as the Investor may reasonably request and registered in such names as the
Investor may request.


 


i.
The Company shall at all times provide a transfer agent and registrar with respect to its Common Stock.


 


j.
If reasonably requested by the Investor, the Company shall (i) immediately incorporate in a prospectus supplement or post-effective
amendment such information as the Investor believes should 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 sold, the purchase
price being paid therefor and any other terms of the offering of the Registrable Securities; (ii) make all required filings of
such prospectus supplement or post-effective amendment as soon as practicable upon notification of the matters to be incorporated
in such prospectus supplement or post-effective amendment; and (iii) supplement or make amendments to any registration statement.


 


k.
The Company shall use commercially reasonable efforts to cause the Registrable Securities covered by any 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.


 


l.
Within three (3) Trading Days after any registration statement which includes the Registrable Securities is ordered effective
by the SEC, the Company shall deliver, and shall cause legal counsel for the Company to deliver, to the transfer agent for such
Registrable Securities (with copies to the Investor) confirmation that such registration statement has been declared effective
by the SEC in the form attached hereto as Exhibit A. Thereafter, if requested by the Buyer at any time, the Company shall
require its counsel to deliver to the Buyer a written confirmation whether or not the effectiveness of such registration statement
has lapsed at any time for any reason (including, without limitation, the issuance of a stop order) and whether or not the registration
statement is current and available to the Buyer for sale of all of the Registrable Securities.


 




    	 



    	 



    

 


m.
The Company shall take all other reasonable actions necessary to expedite and facilitate disposition by the Investor of Registrable
Securities pursuant to any registration statement.


 


4.
OBLIGATIONS OF THE INVESTOR.


 


a.
The Company shall notify the Investor in writing of the information the Company reasonably requires from the Investor in connection
with any registration statement hereunder. The 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 the registration of such Registrable Securities and shall execute such documents in connection with such registration
as the Company may reasonably request.


 


b.
The Investor agrees to cooperate with the Company as reasonably requested by the Company in connection with the preparation and
filing of any registration statement hereunder.


 


c.
The Investor agrees that, upon receipt of any notice from the Company of the happening of any event or existence of facts of the
kind described in Section 3(f) or the first sentence of 3(e), the Investor will immediately discontinue disposition of Registrable
Securities pursuant to any registration statement(s) covering such Registrable Securities until the Investor’s receipt of
the copies of the supplemented or amended prospectus contemplated by Section 3(f) or the first sentence of 3(e). Notwithstanding
anything to the contrary, the Company shall cause its transfer agent to promptly deliver shares of Common Stock without any restrictive
legend in accordance with the terms of the Purchase Agreement in connection with any sale of Registrable Securities with respect
to which an Investor has entered into a contract for sale prior to the Investor’s receipt of a notice from the Company of
the happening of any event of the kind described in Section 3(f) or the first sentence of Section 3(e) and for which the Investor
has not yet settled.


 


5.
EXPENSES OF REGISTRATION.


 


All
reasonable expenses, other than sales or brokerage commissions, incurred in connection with registrations, filings or qualifications
pursuant to Sections 2 and 3, including, without limitation, all registration, listing and qualifications fees, printers and accounting
fees, and fees and disbursements of counsel for the Company, shall be paid by the Company.


 


6.
INDEMNIFICATION.


 


a.
To the fullest extent permitted by law, the Company will, and hereby does, indemnify, hold harmless and defend the Investor, each
Person, if any, who controls the Investor, the members, the directors, officers, partners, employees, agents, representatives
of the Investor and each Person, if any, who controls the Investor within the meaning of the Securities Act or the Securities
Exchange Act of 1934, as amended (the “Exchange Act”) (each, an “Indemnified Person”), against
any losses, claims, damages, liabilities, judgments, fines, penalties, charges, costs, attorneys’ fees, amounts paid in
settlement or expenses, joint or several, (collectively, “Claims”) incurred in investigating, preparing or
defending any action, claim, suit, inquiry, proceeding, investigation or appeal taken from the foregoing by or before any court
or governmental, administrative or other regulatory agency, body or the SEC, whether pending or threatened, whether or not an
indemnified party 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 the Registration Statement, any New 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 the final prospectus (as amended or supplemented, if the Company files any amendment thereof or supplement thereto with the
SEC) or the omission or alleged omission to state therein any material fact necessary to make the statements made therein, in
light of the circumstances under which the statements therein were made, not misleading, (iii) any violation or alleged violation
by the Company of the Securities Act, the Exchange 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 the Registration
Statement or any New Registration Statement or (iv) any material violation by the Company of this Agreement (the matters in the
foregoing clauses (i) through (iv) being, collectively, “Violations”). The Company shall reimburse each Indemnified
Person promptly as such expenses are incurred and are due and payable, for any reasonable legal fees or other reasonable expenses
incurred by them in connection with investigating or defending any such Claim. Notwithstanding anything to the contrary contained
herein, the indemnification agreement contained in this Section 6(a): (i) shall not apply to a Claim by an Indemnified Person
arising out of or based upon a Violation which occurs in reliance upon and in conformity with information about the Investor furnished
in writing to the Company by such Indemnified Person expressly for use in connection with the preparation of the Registration
Statement, any New Registration Statement or any such amendment thereof or supplement thereto, if such prospectus was timely made
available by the Company pursuant to Section 3(c) or Section 3(e); (ii) with respect to any superseded prospectus, shall not inure
to the benefit of any such person from whom the person asserting any such Claim purchased the Registrable Securities that are
the subject thereof (or to the benefit of any person controlling such person) if the untrue statement or omission of material
fact contained in the superseded prospectus was corrected in the revised prospectus, as then amended or supplemented, if such
revised prospectus was timely made available by the Company pursuant to Section 3(c) or Section 3(e), and the Indemnified Person
was promptly advised in writing not to use the incorrect prospectus prior to the use giving rise to a violation and such Indemnified
Person, notwithstanding such advice, used it; (iii) shall not be available to the extent such Claim is based on a failure of the
Investor to deliver or to cause to be delivered the prospectus made available by the Company, if such prospectus was timely made
available by the Company pursuant to Section 3(c) or Section 3(e); and (iv) shall not apply to amounts paid in settlement of any
Claim if such settlement is effected without the prior written consent of the Company, which consent shall not be unreasonably
withheld. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified
Person and shall survive the transfer of the Registrable Securities by the Investor pursuant to Section 9.


 




    	 



    	 



    

 


b.
Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the commencement of any
action or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person or Indemnified
Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section 6, deliver to the indemnifying
party a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to
the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of
the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified
Party, as the case may be; provided, however, that an Indemnified Person or Indemnified Party shall have the right to retain its
own counsel with the fees and expenses to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained
by the indemnifying party, the representation by such counsel of the Indemnified Person or Indemnified Party and the indemnifying
party would be inappropriate due to actual or potential differing interests between such Indemnified Person or Indemnified Party
and any other party represented by such counsel in such proceeding. The Indemnified Party or Indemnified Person shall cooperate
fully with the indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying
party and shall furnish to the indemnifying party all information reasonably available to the Indemnified Party or Indemnified
Person which relates to such action or claim. The indemnifying party shall keep the Indemnified Party or Indemnified Person fully
apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. No indemnifying party
shall be liable for any settlement of any action, claim or proceeding effectuated without its written consent, provided, however,
that the indemnifying party shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall, without
the consent of the Indemnified Party or Indemnified Person, consent to entry of any judgment or enter into any settlement or other
compromise which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified
Party or Indemnified Person of a release from all liability in respect to such claim or litigation. Following indemnification
as provided for hereunder, the indemnifying party shall be subrogated to all rights of the Indemnified Party or Indemnified Person
with respect to all third parties, firms or corporations relating to the matter for which indemnification has been made. The failure
to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall not
relieve such indemnifying party of any liability to the Indemnified Person or Indemnified Party under this Section 6, except to
the extent that the indemnifying party is prejudiced in its ability to defend such action.


 




    	 



    	 



    

 


c.
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.


 


d.
The indemnity agreements contained herein shall be in addition to (i) any cause of action or similar right of the Indemnified
Party or Indemnified Person against the indemnifying party or others, and (ii) any liabilities the indemnifying party may be subject
to pursuant to the law.


 


7.
CONTRIBUTION.


 


To
the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make
the maximum contribution with respect to any amounts for which it would otherwise be liable under Section 6 to the fullest extent
permitted by law; provided, however, that: (i) no seller of Registrable Securities guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any seller of Registrable Securities
who was not guilty of fraudulent misrepresentation; and (ii) contribution by any seller of Registrable Securities shall be limited
in amount to the net amount of proceeds received by such seller from the sale of such Registrable Securities.


 


8.
REPORTS AND DISCLOSURE UNDER THE SECURITIES ACTS.


 


With
a view to making available to the Investor the benefits of Rule 144 promulgated under the Securities Act or any other similar
rule or regulation of the SEC that may at any time permit the Investor to sell Registrable Securities of the Company to the public
without registration (“Rule 144”), the Company agrees, at the Company’s sole expense, to:


 


a.
make and keep public information available, as those terms are understood and defined in Rule 144;


 


b.
use reasonable efforts to file with the SEC in a timely manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act so long as the Company remains subject to such requirements and the filing of such reports
and other documents is required for the applicable provisions of Rule 144;


 


c.
furnish to the Investor so long as the Investor owns Registrable Securities, promptly upon request, (i) a written statement by
the Company that it has complied with the reporting and or disclosure provisions of Rule 144, the Securities Act and the Exchange
Act, (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by
the Company, and (iii) such other information as may be reasonably requested to permit the Investor to sell such securities pursuant
to Rule 144 without registration; and


 


d.
take such additional action as is requested by the Investor to enable the Investor to sell the Registrable Securities pursuant
to Rule 144, including, without limitation, delivering all such legal opinions, consents, certificates, resolutions and instructions
to the Company’s Transfer Agent as may be requested from time to time by the Investor and otherwise fully cooperate with
Investor and Investor’s broker to effect such sale of securities pursuant to Rule 144.


 


9.
ASSIGNMENT OF REGISTRATION RIGHTS.


 


The
Company shall not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Investor.
The Investor may not assign its rights under this Agreement without the written consent of the Company.


 


10.
AMENDMENT OF REGISTRATION RIGHTS.


 


No
provision of this Agreement may be amended or waived by the parties from and after the date that is one (1) Trading Day immediately
preceding the initial filing of the Registration Statement with the SEC. Subject to the immediately preceding sentence, no provision
of this Agreement may be (i) amended other than by a written instrument signed by both parties hereto or (ii) waived other than
in a written instrument signed by the party against whom enforcement of such waiver is sought. 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.

Re:

Ladies
and Gentlemen:


 


We
are counsel to H/CELL ENERGY CORPORATION, a Nevada corporation (the “Company”), and have represented
the Company in connection with that certain Purchase Agreement, dated as of March 12, 2019 (the “Purchase Agreement”),
entered into by and between the Company and TRITON FUNDS LP (the “Buyer”) pursuant to which the Company has
agreed to issue to the Buyer shares of the Company’s Common Stock, $0.001 par value (the “Common Stock “),
in an amount up to Four Hundred Fifty Thousand Dollars ($450,000) (the “Purchase Notice Shares”), in accordance
with the terms of the Purchase Agreement. In connection with the transactions contemplated by the Purchase Agreement, the Company
has registered with the U.S. Securities & Exchange Commission the following shares of Common Stock:


 


(1)
Purchase Notice Shares to be issued to the Buyer upon purchase from the Company by the Buyer from time to time in accordance with
the Purchase Agreement.


 


Pursuant
to the Purchase Agreement, the Company also has entered into a Registration Rights Agreement, of even date with the Purchase Agreement
with the Buyer (the “Registration Rights Agreement”) pursuant to which the Company agreed, among other things,
to register the Purchase Notice Shares under the Securities Act of 1933, as amended (the “Securities Act”).
In connection with the Company’s obligations under the Purchase Agreement and the Registration Rights Agreement, on [__________],
2019, the Company filed a Registration Statement (File No. 333-[__________]) (the “Registration Statement”)
with the Securities and Exchange Commission (the “SEC”) relating to the resale of the Purchase Notice Shares.


 


In
connection with the foregoing, we advise you that a member of the SEC’s staff has advised us by telephone that the SEC has
entered an order declaring the Registration Statement effective under the Securities Act at [__________] [A.M./P.M.] on [__________],
2019 and we have no knowledge, after a review of the SEC’s EDGAR system, 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 Purchase Notice
Shares are available for resale under the Securities Act pursuant to the Registration Statement and may be issued without any
restrictive legend.


 


	 	Very truly yours,
