CAPITAL RIGHT OF FIRST REFUSAL. As an inducement for the Purchaser to enter into the transactions contemplated by the Common

as established by the Company’s advisors. The Purchaser will have access to information consistent with the information provided

FID Capital Preference Amount of FID Capital Securities, then the Company shall be free to issue the FID Capital Securities originally
offered to the Purchaser for which exercise was not made by the Purchaser; provided, however, that if the terms of
such FID Capital Securities allocated for sale to third parties are more favorable than the terms originally offered to the Purchaser,
the Company shall be obligated to offer those same, improved, terms to the Purchaser and the Purchaser shall be allowed another
opportunity to accept or reject such improved terms as provided herein. If the Purchaser elects to purchase any FID Capital Securities
pursuant to Section 2(b), then the Company shall sell to the Purchaser, and the Purchaser shall purchase from the Company,
for the consideration and on the terms as established by the syndication process, the FID Capital Securities that the Purchaser
has duly elected to purchase pursuant to Section 2(c) and the Company may issue the remaining FID Capital Securities it
proposed to issue in such FID Capital Notice in accordance with this Section 2(b).

(d)       If
the sale of the FID Capital Securities is not completed within six (6) months of the date on which the FID Capital Notice is given,
then the Company shall not thereafter sell FID Capital Securities without complying anew with the procedures described in this
Section 2.

(e)       Upon
the reasonable advice of its financial advisor, the Company may modify the process and timing of the transactions described in

Concurrently with the issuance of the Common Stock to the Purchaser or its Affiliate, the Board shall (i) increase the number of
natural persons that constitute the whole Board by at least one (1) person and (ii) fill one such vacancy created by virtue of
such increase in the size of the Board with an individual designated by the Purchaser (the “Designated Director”);
provided,  however, that the Designated Director shall, in the reasonable judgment of the Company, (A) have
the requisite skill and experience to serve as a director of a publicly traded company, (B) not be prohibited or disqualified from
serving as a director of the Company pursuant to any rule or regulation of the Commission, any Self-Regulatory Organization, or
by applicable Law, or be subject to any “Bad Actor” disqualification set forth in Rule 506(d) under the Securities
Act of 1934, as amended, and (C) otherwise be reasonably acceptable to the Company.  The Company shall use reasonable
efforts to ensure that the Designated Director is assigned as a “Class B” director in accordance with the Second Amended
and Restated Certificate of Incorporation of the Company.  The Company covenants to indemnify the Designated Director
and, prior to the appointment of the Designated Director, agrees to execute an indemnification agreement substantially in the form
attached hereto as Exhibit A. The Purchaser and the Designated Director agree to provide the Company with accurate and complete
information relating to the Purchaser and the Designated Director that may be required to be disclosed by Company under the Securities
and Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder.  In addition, at the Company’s
request, the Purchaser shall cause the Designated Director to complete and execute the Company’s Standard Director and Officer
Questionnaire prior to being admitted to the Board or standing for reelection at an annual meeting of stockholders or at such other
time as may be requested by the Company.

    	 	5	 

     

    

 

(b)       Until
a Termination Event, and subject to the conditions of Section 3(a), the Company shall nominate the Designated Director for
re-election to the Board at each annual meeting of stockholders at which the Designated Director is up for re-election.  The
Designated Director will hold office until his or her term expires in accordance with the bylaws of the Company and such Designated
Director’s successor has been duly elected and qualified or until such Designated Director’s earlier death, resignation
or removal.

(c)       Prior
to a Termination Event:

(i)       in
connection with each annual meeting of stockholders, and subject to the conditions of Section 3(a), the Board shall unanimously
recommend that the stockholders of the Company vote “FOR” the election of the Designated Director and shall use all
commercially reasonable efforts to cause the election of the Designated Director to the Board, including soliciting proxies in
favor of his or her election;

(ii)       any
Designated Director may be removed by the Purchaser at any time in the Purchaser’s sole discretion, and any vacancy created
by such removal shall be filled by the Board with an individual designated by the Purchaser who, subject to the conditions of Section
3(a), shall become the Designated Director; and

(iii)       upon
written notice from the Company to the Purchaser that a Resignation Event has occurred, which notice shall set forth in reasonable
detail the facts and circumstances constituting the Resignation Event, the Purchaser will cause the Designated Director then serving
as a member of the Board to resign as a member of the Board within two (2) Business Days of such written notice, and any vacancy
created by such resignation shall be filled by the Board with an individual designated by the Purchaser who, subject to the conditions
of Section 3(a), shall become the Designated Director.

(d)       Any
action by the Purchaser to designate or replace the Designated Director shall be evidenced in writing furnished to the Company
and shall be signed by or on behalf of the Purchaser.

(e)       Prior
to designating a Designated Director, the Purchaser shall enter into a written agreement with the Designated Director whereby such
Designated Director agrees to resign as a member of the Board upon a Resignation Event. The Purchaser acknowledges and agrees that
such an agreement is in the best interest of the Company and the Purchaser, and that the Company shall be a third party beneficiary
of the terms and conditions of such an agreement, and the Company shall have the right to enforce such an agreement to the same
extent as the parties thereto.

(f)       The
Company shall not take any action that would lessen, restrict, prevent or otherwise have an adverse effect upon the foregoing rights
of the Purchaser to Board representation; provided, however, that the Company shall not be prohibited from taking
such action that the Board determines may be necessary to (A) comply with any rule or regulation of the Commission or any Self-Regulatory
Organization or (B) comply with applicable Law.

    	 	6	 

     

    

 

(g)       Except
as the Purchaser may otherwise agree in writing, the Purchaser and its Affiliates shall have the right to (i) engage, directly
or indirectly, in the same or similar business activities or lines of business as the Company and (ii) do business with any client,
competitor or customer of the Company, with the result that the Company shall have no right in or to such activities or any proceeds
or benefits therefrom, and except as otherwise provided in this Agreement, neither the Purchaser nor any of its Affiliates shall
be liable to the Company or its stockholders for breach of any fiduciary duty by reason of any such activities of the Purchaser
or its Affiliates participation therein. If the Purchaser acquires knowledge of a potential transaction or matter that may be a
corporate opportunity for both the Company and the Purchaser or its Affiliates, then the Purchaser and its Affiliates shall have
no duty to communicate or present such corporate opportunity to the Company and the Company hereby renounces any interest or expectancy
it may have in such corporate opportunity, with the result that neither the Purchaser nor any of its Affiliates shall be liable
to the Company or its stockholders for breach of any fiduciary duty, including for breach of any fiduciary duty as a stockholder
of the Company by reason of the fact that the Purchaser pursues or acquires such corporate opportunity for itself, directs such
corporate opportunity to another Person, or does not present such corporate opportunity to the Company. The Company shall indemnify
the Purchaser and its Affiliates against any losses resulting from any breach of fiduciary duty or other claim brought by or through
the Company or any stockholder of the Company with respect to the matters contemplated by this Section 3(g)‎. Notwithstanding
the foregoing, if the Purchaser acquires knowledge of a potential transaction or matter that may be a corporate opportunity
for both the Company, on the one hand, and the Purchaser or its Affiliates, on the other, as a result of information shared by
the Company to with members of the Board, including the Designated Director, then such corporate opportunity belongs to the Company,
and the Purchaser shall be liable to the Company and its stockholders for breach of any fiduciary duty, including for breach of
any fiduciary duty as a stockholder of the Company by reason of the fact that the Purchaser or its Affiliates usurps such corporate
opportunity for itself, or directs such corporate opportunity to another Person.

Section 4.       MISCELLANEOUS.

4.5       No

Party’s performance of any obligation under this Agreement shall not affect the right subsequently to require performance
of that obligation. Any waiver of any breach of any provision of this Agreement shall not be construed as a waiver of any continuing
or succeeding breach of such provision or a waiver or modification of any other provision.

The section and subsection headings in this Agreement are inserted for convenience only and shall not affect in any way the meaning
or interpretation of this Agreement.

4.8       Severability.
If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy,
all other terms and provisions of this Agreement shall nevertheless remain in full force and effect for so long as the economic
or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party. Upon
such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate
in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable
manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

4.9

hereof or at least fifty percent (50%) of the Purchaser’s FID ROFR rights with respect to FID Debt Securities held as of
the date hereof. For avoidance of doubt, in the event the Purchaser transfers only fifty percent (50%) of its FID ROFR rights with
respect to either its FID Equity Securities or FID Debt Securities, the Purchaser shall retain the right to transfer the remaining
fifty percent (50%) of such FID Equity Securities or FID Debt Securities, as applicable, subject to the terms of this Section
4.10(c). The Purchaser shall have the right to transfer its FID ROFR rights with respect to FID Equity Securities and FID Debt
Securities independently of each other. Following the Purchaser’s being provided the opportunity to exercise its FID ROFR
rights pursuant to a FID Capital Notice with respect to the Company’s first two liquefaction units to be constructed as part
of the Project, and provided that an FID has in fact occurred in respect of such first two liquefaction units, the Purchaser shall
be entitled to transfer all of its remaining FID ROFR rights with respect to each of its FID Equity Securities and its FID Debt
Securities to a single transferee even if such remaining FID ROFR rights are less than the fifty percent (50%) of the Purchaser’s
FID ROFR rights with respect to FID Equity Securities held as of the date hereof or are less than fifty percent (50%) of the Purchaser’s
FID ROFR rights with respect to FID Debt Securities held as of the date hereof. The Purchaser and the transferee of any such FID
ROFR rights shall determine the terms of conditions of the transfer of such FID ROFR rights. The Purchaser shall retain any FID
ROFR rights not so transferred until either exercised or transferred.

Section 4.10 shall not preclude, impede or restrict the Purchaser’s ability to sell, transfer, assign or dispose of its shares
of Common Stock. The Purchaser may transfer its FID ROFR rights independently of the sale of any shares of Common Stock, and may
sell shares of Common Stock without transferring any of its FID ROFR rights.

(e)       Except
as set forth in this Section 4.10 or as otherwise agreed by the Parties in writing, neither this Agreement nor any of the
rights, interests or obligations under this Agreement (including the Purchaser’s right to appoint a Designated Director pursuant
to Section 3 hereof) may be assigned by either Party (whether by operation of law or otherwise) without the prior written consent
of the other Party.

4.11       No

suit or proceeding may be effected by providing a copy thereof by any of the methods of delivery permitted by Section 4.6
to such Party at its address as provided in Section 4.6 (provided that nothing herein shall affect the right to effect service

    	 	10	 

     

    

 

4.15       Waiver
of Jury Trial. EACH OF THE PARTIES HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY
HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT
(WHETHER BASED ON CONTRACT, TORT, OR ANY OTHER THEORY). EACH OF THE PARTIES HERETO HEREBY (A) CERTIFIES THAT NO REPRESENTATIVE,
AGENT OR ATTORNEY OF THE OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED

to be their original signatures for all purposes.

4.17       Specific
Performance. Each Party acknowledges that, in view of the uniqueness of the securities referenced herein and the transactions
contemplated by this Agreement, the other Party would not have an adequate remedy at law for money damages in the event that this
Agreement has not been performed in accordance with its terms, and therefore agrees that the other Party shall be entitled to specific
performance and injunctive or other equitable relief, without the necessity of proving the inadequacy of monetary damages as a
remedy.

4.18       Amendment
of Company Documents. Neither the Company nor the Board shall (a) permit the bylaws or certificate of incorporation of the
Company to be amended in any manner that would eliminate or have any negative impact on any of the provisions hereof or the rights

and provisions of this Agreement.

4.19       Waiver

Section 2.       SHELF REGISTRATIONS,
DEMAND REGISTRATIONS AND PIGGYBACK REGISTRATIONS.

(a)       Shelf
Registration.

(i)       Filing.
The Company shall, as soon as practicable after the date of this Agreement, but in any event within forty-five (45) days after
the date of this Agreement, file a Registration Statement under the Securities Act to permit the public resale of all the Registrable
Securities held by the Holders from time to time as permitted by Rule 415 under the Securities Act (or any successor or similar
provision adopted by the Commission then in effect) (the “Shelf Registration Statement”) on the terms and conditions
specified in this Section 2(a) and shall use its reasonable best efforts to cause such Shelf Registration Statement to be declared
effective as soon as practicable after the filing thereof, but in any event no later than the earlier of (i) sixty (60) days (or
ninety (90) days if the Commission notifies the Company that it will “review” the Shelf Registration Statement) after
the date that is forty-five (45) days from the date of this Agreement and (ii) the tenth (10th) business day after the date the
Company is notified (orally or in writing, whichever is earlier) by the Commission that such Shelf Registration Statement will
not be “reviewed” or will not be subject to further review (such earlier date, the “Effectiveness Deadline”).
The Shelf Registration Statement filed with the Commission pursuant to this Section 2(a) shall be on Form S-3 or, if Form S-3 is
not then available to the Company, on Form S-1 or such other form of registration statement as is then available to effect a registration
for resale of such Registrable Securities, covering such Registrable Securities, and shall contain a prospectus in such form as
to permit any Holder to sell such Registrable Securities pursuant to Rule 415 under the Securities Act (or any successor or similar
provision adopted by the Commission then in effect) at any time beginning on the effective date for such Shelf Registration Statement.
A Shelf Registration Statement filed pursuant to this Section 2(a) shall provide for the resale pursuant to any method or combination
of methods legally available to, and requested by, the Holders.  As soon as practicable following the effective date of a
Shelf Registration Statement filed pursuant to this Section 2(a), but in any event within three (3) business days of such date,
the Company shall notify the Holders of the effectiveness of such Registration Statement. When effective, a Shelf Registration
Statement filed pursuant to this Section 2(a) (including the documents incorporated therein by reference) will comply as to form
in all material respects with all applicable requirements of the Securities Act and the Exchange Act and will not 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 not misleading (in the case of any prospectus contained in such Shelf Registration Statement, in the light of the circumstances
under which such statement is made). 

    	 	 5	 

     

    

 

(ii)       Continued
Effectiveness. The Company shall use its reasonable best efforts to cause the Shelf Registration Statement to remain effective
and to be supplemented and amended to the extent necessary to ensure that such Shelf Registration Statement is available or, if
not available, that another registration statement is available, for the resale of all the Registrable Securities held by the Holders
until the earliest of (A) the date all such Registrable Securities have ceased to be Registrable Securities and (B) the date all
such Registrable Securities covered by such Shelf Registration Statement can be sold publicly without restriction or limitation
under Rule 144 under the Securities Act and without the requirement to be in compliance with Rule 144(c)(1) under the Securities
Act.

(iii)       Underwritten
Offering and Selection of Underwriters. If the Holders of at least 20.0% of the then outstanding number of Registrable Securities
held by the Holders (the “Underwritten Demand Holders”) elect to dispose of Registrable Securities under a Shelf
Registration Statement or other Registration Statement pursuant to an Underwritten Offering of all or part of such Registrable
Securities that are registered by such Shelf Registration Statement or other Registration Statement and reasonably expect aggregate
gross proceeds in excess of $10,000,000 (the “Holders’ Minimum Amount”) from such Underwritten Offering,
then the Company shall, upon the written demand of such Underwritten Demand Holder(s), enter into an underwriting agreement in
a form as is customary in Underwritten Offerings of securities by the Company with the managing underwriter or underwriters selected
by the Underwritten Demand Holders and shall take all such other reasonable actions as are requested by the managing underwriter
or underwriters in order to expedite or facilitate the disposition of such Registrable Securities; provided, however, that the
Company shall have no obligation to facilitate or participate in more than two (2) Underwritten Offerings in any twelve (12)-month
period pursuant to this Section 2(a) or Section 2(b).  In connection with any Underwritten Offering contemplated by this Section
2(a) or Section 2(b), the underwriting agreement into which each Holder and the Company shall enter shall contain such representations,
covenants, indemnities and other rights and obligations as are customary in underwritten offerings of securities by the Company.
No Holder shall be required to make any representations or warranties to or agreements with the Company or the underwriters
other than representations, warranties or agreements regarding such Holder’s authority to enter into such underwriting agreement
and to sell, and its ownership of, the securities being registered on its behalf, its intended method of distribution, the accuracy
of information provided by a Holder specifically for use in the Registration Statement or Prospectus, and any other representation
required by law; provided, that each Holder other than the Underwritten Demand Holders shall be afforded five (5) Business
Days to decide to include in any such Underwritten Offering up to its pro rata share of Registrable Securities based on the percentage
of Registrable Securities owned by the Underwritten Demand Holders that are included in such Underwritten Offering; provided
further, that to the extent such other Holders wish to include additional Registrable Securities held by such Holders in an
Underwritten Offering in excess of their allotted proportion, such other Holders may request, within the same five (5) Business
Day notice period outlined above, that the Underwritten Demand Holders consider including such additional shares as Registrable
Securities.  Upon receipt of such notice, and subject to Section 2(d)(i), the Underwritten Demand Holders may elect to include
or exclude such additional Registrable Securities from the Underwritten Offering in their sole and absolute discretion.

    	 	 6	 

     

    

 

(b) Demand Registrations.

(i)        Right
to Request Registration. So long as the Company does not have an effective Shelf Registration Statement with respect to the
Registrable Securities following the Effectiveness Deadline, the Holders of at least twenty percent (20%) of the then-outstanding
number of Registrable Securities (the “Demand Holders”) may request registration under the Securities Act of
all or part of their Registrable Securities with an anticipated aggregate offering price of at least $10,000,000 at any time and
from time to time (“Demand Registration”).

Within seven (7)
Business Days after receipt of any such request for Demand Registration, the Company shall give written notice of such request
to each other Holder of Registrable Securities, if any, and shall, subject to the provisions of Section 2(d)(i) hereof, include
in such registration up to the pro rata share Registrable Securities of each such Holder based on the percentage Registrable Securities
owned by the Demand Holders that are to be included in the Demand Registration and with respect to which the Company has received
written requests for inclusion therein within five (5) Business Days after the receipt of the Company’s notice; provided,
that to the extent such other Holders wish to include additional Registrable Securities held by such Holders in the Demand Registration
in excess of their allotted proportion, such other Holders may request, within the same five (5) Business Day notice period outlined
above, that the Demand Holders consider including such additional shares as Registrable Securities. Upon receipt of such notice,
and subject to Section 2(d)(i), the Demand Holders may elect to include or exclude such additional Registrable Securities from
the Demand Registration in their sole and absolute discretion. The Company shall use its reasonable best efforts to file with the
Commission following receipt of any such request for Demand Registration (but in no event more than thirty (30) days following
receipt of such request) one or more registration statements with respect to all such Registrable Securities with respect to which
the Company has received written requests for inclusion therein in accordance with this paragraph under the Securities Act (the
“Demand Registration Statement”). The Company shall use its reasonable best efforts to cause such Demand Registration
Statement to be declared effective by the Commission as soon as practicable after the filing thereof. The Demand Registration Statement
shall be on an appropriate form and the Registration Statement and any form of Prospectus included therein (or Prospectus supplement
relating thereto) shall reflect the plan of distribution or method of sale as the Holders of shares registered on such Registration
Statement may from time to time notify the Company. Subject to the foregoing and to Section 2(d)(i), following the receipt by the
Company of any request for Demand Registration, all of the Registrable Securities of any Holder electing to register Registrable
Securities in accordance with this paragraph shall be included in the Demand Registration Statement without any further action
by any Holder. The Demand Holders who have requested a Demand Registration may cause the Company to postpone or withdraw the filing
or the effectiveness of such Demand Registration at any time in their sole discretion.

(ii)       Restrictions
on Demand Registrations. The Company shall not be obligated to effect any Demand Registration within ninety (90) days after
the effective date of (A) a previous Demand Registration or (B) a previous registration under which any Holder or Holders had piggyback
rights pursuant to Section 2(c) hereof and in which the Holders exercising such piggyback rights were permitted to register, and
sold, at least fifty percent (50%) of the Registrable Securities requested to be included therein. In addition, the Company shall
not be obligated to effect any Demand Registration after the Company has effected two (2) Demand Registrations in any twelve (12)-month
period if all such registrations effected by the Company have been declared and ordered effective.

    	 	 7	 

     

    

 

(iii)       Underwritten
Offering and Selection of Underwriters. If the Underwritten Demand Holders elect to dispose of Registrable Securities under
a Demand Registration pursuant to an Underwritten Offering, then each other Holder shall be afforded the right to include in any
such Underwritten Offering up to its pro rata share of Registrable Securities based on the percentage of Registrable Securities
owned by the Underwritten Demand Holders that are included in such Underwritten Offering. If any of the Registrable Securities
covered by a Demand Registration hereof are to be sold in an Underwritten Offering, then the Underwritten Demand Holders shall
have the right to select the managing underwriter or underwriters to administer any such Underwritten Offering.

(iv) Effective
Period of Demand Registrations. After any Demand Registration Statement filed pursuant to this Agreement has become effective,
the Company shall use its reasonable best efforts to keep such Demand Registration Statement effective for a period equal to one
hundred eighty (180) days from the date on which the Commission declares such Demand Registration Statement effective (or if such
Demand Registration Statement is not effective during any period within such one hundred eighty (180) days, such 180-day period
shall be extended by the number of days during such period when such Demand Registration Statement is not effective), or such shorter
period that shall terminate when all of the Registrable Securities covered by such Demand Registration Statement have been sold
pursuant to such Demand Registration. If the Company shall withdraw or reduce the number of shares of Registrable Securities that
is subject to any Demand Registration pursuant to Section 2(d)(i) (a “Withdrawn Demand Registration”), the Demand
Holders of the Registrable Securities remaining unsold and originally covered by such Withdrawn Demand Registration shall be entitled
to a replacement Demand Registration that (subject to the provisions of this Section 2(b)) the Company shall use its reasonable
best efforts to keep effective for a period commencing on the effective date of such Demand Registration and ending on the earlier
to occur of the date (i) that is one hundred eighty (180) days from the effective date of such Demand Registration and (ii) on
which all of the Registrable Securities covered by such Demand Registration have been sold. Such additional Demand Registration
otherwise shall be subject to all of the provisions of this Agreement.

(c) Piggyback
Registrations.

(i)       Right
to Piggyback. Whenever the Company proposes to register any of its Common Stock under the Securities Act (other than a registration
statement on Form S-8 or on Form S-4 or any similar successor forms thereto), whether for its own account or for the account of
one or more stockholders of the Company, and the registration form to be used may be used for any registration of Registrable Securities
(a “Piggyback Registration”), the Company shall give prompt (but in no event less than ten (10) days before
the anticipated filing date of such registration statement) written notice to all Holders of its intention to effect such a registration,
which notice shall (A) describe the amount and type of securities to be included in such offering, the intended method of distribution,
and the name of the proposed managing underwriter, if any, in such offering, and (B) offer to all Holders of Registrable Securities
the opportunity to register the same of such number of Registrable Securities as such Holders may request in writing within five
(5) Business Days after receipt of such written notice from the Company. The Company shall, subject to Sections 2(d)(ii) and 2(d)(iii),
include in such registration all Registrable Securities with respect to which the Company has received written requests for inclusion
therein within five (5) Business Days after the receipt of the Company’s notice. The Company may postpone or withdraw the
filing or the effectiveness of a Piggyback Registration at any time in its sole discretion upon reasonable notice to any participating
Holders.

    	 	 8	 

     

    

 

(ii)       Withdrawal.
Any Holder may elect to withdraw such Holder’s request for inclusion of Registrable Securities in any Piggyback Registration
by giving written notice to the Company of such request to withdraw prior to the effectiveness of the Registration Statement. The
Company (whether on its own determination or as the result of a withdrawal by Persons making a demand pursuant to written contractual
obligations) may withdraw a Registration Statement at any time prior to the effectiveness of the Registration Statement without
thereby incurring any liability to the Holders of Registrable Securities. Notwithstanding any such withdrawal, the Company shall
pay all expenses incurred by the Holders in connection with such Piggyback Registration as provided in Section 8(d).

(iii)       Selection
of Underwriters. If any of the Registrable Securities of the Holders covered by a Piggyback Registration hereof are to be sold
in an Underwritten Offering, then the Company shall have the right to select the managing underwriter or underwriters to administer
any such offering.

(d) Priority.

(i)       Priority
on Shelf and Demand Registrations. If the managing underwriters of a requested Demand Registration or an Underwritten Offering
under a Shelf Registration Statement advise the Company in writing that, in their opinion, the number of Registrable Securities
requested to be included in such Demand Registration Statement or Shelf Registration Statement exceeds the number that can be sold
in such offering and/or that the number of Registrable Securities proposed to be included in any such registration would adversely
affect the price per share of the Company’s equity securities to be sold in such offering (such maximum number of securities
or Registrable Securities, as applicable, the “Maximum Threshold”), the underwriting shall be allocated among
the Company and all Holders as follows: (A) first, the shares comprised of Registrable Securities, as to which registration has
been requested and is required pursuant to the registration rights hereof, based on the amount of such Registrable Securities initially
requested to be registered by such Holders that can be sold without exceeding the Maximum Threshold; (B) second, to the extent
that the Maximum Threshold has not been reached under the foregoing clause (A), the shares of Common Stock or other securities
that the Company desires to sell that can be sold without exceeding the Maximum Threshold; and (C) third, to the extent the Maximum
Threshold has not been reached under the foregoing clauses (A) and (B), any additional Registrable Securities of Holders other
than the Demand Holders or Underwritten Demand Holders as to which registration has been requested and that the Demand Holders
or Underwritten Demand Holders, as applicable, determine, in their sole discretion, can be sold.

    	 	 9	 

     

    

 

(ii) Priority
on Primary Registrations. If a Piggyback Registration is an underwritten primary registration on behalf of the Company, and
the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included
in such registration exceeds the Maximum Threshold, the underwriting shall be allocated among the Company and all Holders as follows:
(A) first, the shares of Common Stock or other securities that the Company desires to sell that can be sold without exceeding the
Maximum Threshold; and (B) second, to the extent that the Maximum Threshold has not been reached under the foregoing clause (A),
the shares comprised of Registrable Securities, as to which registration has been requested pursuant to the registration rights
hereof, based on the amount of such Registrable Securities initially requested to be registered by such Holders that can be sold
without exceeding the Maximum Threshold.

(iii)       Underwritten
Block Trades. Notwithstanding the foregoing, if the Holders of at least twenty percent (20%) of the then-outstanding number
of Registrable Securities wish to engage in an underwritten block trade off of an effective Shelf Registration Statement, Demand
Registration Statement or Piggyback Registration, such Holders may notify the Company of the block trade offering on the day such
offering is to commence and the Company shall as expeditiously as possible use its reasonable best efforts to facilitate such offering
(which may close as early as three (3) Business Days after the date it commences); provided that in the case of such underwritten
block trade, only such Holders shall have a right to notice of and to participate in such offering.

Section 3.       BLACK-OUT PERIODS.

(a)       Notwithstanding
Section 2, and subject to the provisions of this Section 3, the Company shall be permitted, in limited circumstances,
to suspend the use, from time to time, of the Prospectus that is part of a Shelf Registration Statement (and therefore suspend
sales of the Registrable Securities under such Shelf Registration Statement), by providing written notice (a “Suspension
Notice”) to the Selling Holders’ Counsel, if any, and the Holders, for such times as the Company reasonably may
determine is necessary and advisable (but in no event for more than an aggregate of ninety (90) days in any rolling twelve (12)-month
period commencing on the date of this Agreement or more than forty-five (45) consecutive days, except as a result of a refusal
by the Commission to declare any post-effective amendment to the Shelf Registration Statement effective after the Company has used
all reasonable best efforts to cause the post-effective amendment to be declared effective by the Commission, in which case, the
Company must terminate the black-out period immediately following the effective date of the post-effective amendment) if either
of the following events shall occur: (i) a majority of the Board determines in good faith that (A) the offer or sale
of any Registrable Securities would materially impede, delay or interfere with any proposed financing, offer or sale of securities,
acquisition, corporate reorganization or other material transaction involving the Company, (B) after the advice of counsel,
the sale of Registrable Securities pursuant to the Shelf Registration Statement would require disclosure of non-public material
information not otherwise required to be disclosed under applicable law, and (C) (x) the Company has a bona fide business
purpose for preserving the confidentiality of such transaction, (y) disclosure would have a material adverse effect on the
Company or the Company’s ability to consummate such transaction, or (z) such transaction renders the Company unable
to comply with Commission requirements, in each case under circumstances that would make it impractical or inadvisable to cause
the Shelf Registration Statement (or such filings) to become effective or to promptly amend or supplement the Shelf Registration
Statement on a post-effective basis, as applicable; or (ii) a majority of the Board determines in good faith, upon the advice
of counsel, that it is in the Company’s best interest or it is required by law, rule or regulation to supplement the Shelf
Registration Statement or file a post-effective amendment to the Shelf Registration Statement in order to ensure that the Prospectus
included in the Shelf Registration Statement (1) contains the information required under Section 10(a)(3) of the Securities
Act; (2) discloses any facts or events arising after the effective date of the Shelf Registration Statement (or of the most
recent post-effective amendment) that, individually or in the aggregate, represents a fundamental change in the information set
forth therein; or (3) discloses any material information with respect to the plan of distribution that was not disclosed in
the Shelf Registration Statement or any material change to such information. Upon the occurrence of any such suspension, the Company
shall use its reasonable best efforts to cause the Shelf Registration Statement to become effective or to promptly amend or supplement
the Shelf Registration Statement on a post-effective basis or to take such action as is necessary to make resumed use of the Shelf
Registration Statement as soon as possible. 

    	 	 10	 

     

    

 

(b)       In
the case of an event that causes the Company to suspend the use of a Shelf Registration Statement as set forth in paragraph (a)
above (a “Suspension Event”), the Company shall give a Suspension Notice to the Selling Holders’ Counsel,
if any, and the Holders to suspend sales of the Registrable Securities and such Suspension Notice shall state generally the basis
for the notice and that such suspension shall continue only for so long as the Suspension Event or its effect is continuing and
the Company is using its reasonable best efforts and taking all reasonable steps to terminate suspension of the use of the Shelf
Registration Statement as promptly as possible. A Holder shall not effect any sales of the Registrable Securities pursuant to such
Shelf Registration Statement (or such filings) at any time after it has received a Suspension Notice from the Company and prior
to receipt of an End of Suspension Notice (as defined below). If so directed by the Company, each Holder will deliver to the Company
(at the expense of the Company) all copies other than permanent file copies then in such Holder’s possession of the Prospectus
covering the Registrable Securities at the time of receipt of the Suspension Notice. The Holders may recommence effecting sales
of the Registrable Securities pursuant to the Shelf Registration Statement (or such filings) following further written notice to
such effect (an “End of Suspension Notice”) from the Company, which End of Suspension Notice shall be given
by the Company to the Holders and to the Selling Holders’ Counsel, if any, promptly following the conclusion of any Suspension
Event and its effect. 

(c)       Notwithstanding
any provision herein to the contrary, if the Company shall give a Suspension Notice with respect to any Shelf Registration Statement
pursuant to this Section 3, the Company agrees that it shall extend the period of time during which such Shelf Registration
Statement shall be maintained effective pursuant to this Agreement by the number of days during the period from the date of receipt
by the Holders of the Suspension Notice to and including the date of receipt by the Holders of the End of Suspension Notice and
provide copies of the supplemented or amended Prospectus necessary to resume sales, with respect to each Suspension Event; provided
that such period of time shall not be extended beyond the date that Common Stock covered by such Shelf Registration Statement are
no longer Registrable Securities.

is declared effective by the Commission, and do any and all other acts and things which may be reasonably necessary or advisable
to enable each such Holder and underwriter to consummate the disposition in each such jurisdiction of such Registrable Securities
owned by such Holder; provided, however, that the Company shall not be required to (1) qualify as a foreign corporation
or as a dealer in securities in any jurisdiction where it would not otherwise be required to qualify but for this Section 4(a)(iv),

underwriting agreement, securities sales agreement or other similar agreement, if any, relating to the offering cease to be true
and correct in all material respects, (5) of the happening of any event or the discovery of any facts during the period a

therein contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary
to make the statements therein not misleading or, in the case of the Prospectus, contains any untrue statement of a material fact
or omits to state any 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 (which information shall be accompanied by an instruction to suspend the
use of the Registration Statement and the Prospectus (such instruction to be provided in the same manner as a Suspension Notice)
until the requisite changes have been made, at which time notice of the end of suspension shall be delivered in the same manner
as an End of Suspension Notice), (6) of the receipt by the Company of any notification with respect to the suspension of the
qualification of the Registrable Securities, for sale in any jurisdiction or the initiation or threatening of any proceeding for
such purpose and (7) of the filing of a post-effective amendment to such Registration Statement;

possible moment;

(viii)       furnish
to each Holder of Registrable Securities, and each underwriter, if any, without charge, at least one conformed copy of each Registration
Statement and any post-effective amendment thereto, including financial statements and schedules contained therein (without documents
incorporated therein by reference and all exhibits thereto, unless requested);

(ix)       cooperate
with the selling Holders to facilitate the timely preparation and delivery of certificates representing Registrable Securities
to be sold and not bearing any restrictive legends; and enable such Registrable Securities to be in such denominations and registered
in such names as the selling Holders or the underwriters, if any, may reasonably request at least two (2) Business Days prior to
the closing of any sale of Registrable Securities;

(x)       upon
the occurrence of any event or the discovery of any facts, as contemplated by Sections 4(a)(v)(5) and 4(a)(v)(6) hereof, as
promptly as practicable after the occurrence of such an event, use its reasonable best efforts to prepare a supplement or post-effective
amendment to the Registration Statement or the related Prospectus or any document incorporated therein by reference or file any
other required document so that, as thereafter delivered to the purchasers of the Registrable Securities, such Prospectus will
not contain at the time of such delivery any untrue statement of a material fact or omit to state a material fact necessary to
make the statements therein, in light of the circumstances under which they were made, not misleading, or will remain so qualified,
as applicable. At such time as such public disclosure is otherwise made or the Company determines that such disclosure is not necessary,

(xiii)       enter
into agreements (including underwriting agreements) and take all other customary appropriate actions in order to expedite or facilitate
the disposition of such Registrable Securities whether or not an underwriting agreement is entered into and whether or not the
registration is an underwritten registration: 

    	 	 14	 

     

    

 

1.       make
such representations and warranties to the Holders of such Registrable Securities and the underwriters, if any, in form, substance
and scope as are customarily made by issuers to underwriters in similar Underwritten Offerings as may be reasonably requested by
them;

2.       obtain
opinions of counsel to the Company and updates thereof (which counsel and opinions (in form, scope and substance) shall be reasonably
satisfactory to any managing underwriter(s) and their counsel) addressed to the underwriters, if any (and in the case of an underwritten
registration, each selling Holder), covering the matters customarily covered in opinions requested in Underwritten Offerings and
such other matters as may be reasonably requested by the underwriter(s);

and all other parties to be indemnified pursuant to said Section or, at the request of any underwriters, in the form customarily
provided to such underwriters in similar types of transactions; and

6.       deliver
such documents and certificates as may be reasonably requested and as are customarily delivered in similar offerings to the Holders

(xiv)       make
available for inspection by any underwriter participating in any disposition pursuant to a Registration Statement, Selling Holders’
Counsel and any accountant retained by a Majority of the Registrable Securities being sold, all financial and other records, pertinent
corporate documents and properties or assets of the Company reasonably requested by any such Persons, and cause the respective
officers, directors, employees, and any other agents of the Company to supply all information reasonably requested by any such
representative, underwriter, counsel or accountant in connection with a Registration Statement, and make such representatives of

that the Selling Holders’ Counsel, if any, and the representatives of any underwriters will use its reasonable best efforts,
to the extent reasonably practicable, to coordinate the foregoing inspection and information gathering and to not materially disrupt
the Company’s business operations; 

(xv)       a

thereto, as the underwriter or underwriters, or in the case of changes received from Selling Holders’ Counsel relating to
the selling Holders or the plan of distribution of Registrable Securities, as Selling Holders’ Counsel, reasonably requests;
not file any such document in a form to which any underwriter shall not have previously been advised and furnished a copy of or
to which the Selling Holders’ Counsel, if any, on behalf of the Holders of Registrable Securities, or any underwriter shall

of the Company available for discussion of such document as shall be reasonably requested by the Selling Holders’ Counsel,
if any, on behalf of such Holders, Selling Holders’ Counsel or any underwriter;

practicable, an earnings statement covering at least twelve (12) months which shall satisfy the provisions of Section 11(a)
of the Securities Act and Rule 158 thereunder;

(xviii)       cooperate
and assist in any filings required to be made with the FINRA and in the performance of any due diligence investigation by any underwriter

the rules and regulations of the FINRA);

    	 	 16	 

     

    

 

(xix)       if

(xx)       cause

and rating agencies, as the case may be, (ii) take other actions to obtain ratings for any Registrable Securities and (iii) use
their reasonable best efforts to cooperate as reasonably requested by the underwriters in the offering, marketing or selling of
the Registrable Securities.

(b)       The
Company may (as a condition to a Holder’s participation in a Shelf Registration, Demand Registration or Piggyback Registration)
require each Holder of Registrable Securities to furnish to the Company such information regarding the Holder and the proposed
distribution by such Holder of such Registrable Securities as the Company may from time to time reasonably request in writing.

(c)       Each
Holder agrees that, upon receipt of any notice from the Company of the happening of any event or the discovery of any facts of
the type described in Section 4(a)(v) hereof, such Holder will forthwith discontinue disposition of Registrable Securities
pursuant to a Registration Statement relating to such Registrable Securities until such Holder’s receipt of the copies of
the supplemented or amended Prospectus contemplated by Section 4(a)(v) hereof, and, if so directed by the Company, such Holder
will deliver to the Company (at the Company’s expense) all copies in such Holder’s possession, other than permanent
file copies then in such Holder’s possession, of the Prospectus covering such Registrable Securities current at the time
of receipt of such notice.

Section 5.       INDEMNIFICATION.

(a)       Indemnification
by the Company. The Company agrees to indemnify and hold harmless each Holder, and the respective officers, directors, partners,
employees, representatives and agents of any such Person, and each Person (a “Controlling Person”), if any,
who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) any of the foregoing
Persons, as follows: 

(i)       against
any and all loss, penalty, liability, claim, damage, judgment, suit, action, other liabilities and expenses whatsoever (“Liabilities”),
as incurred, arising out of or based on any untrue statement or alleged untrue statement of a material fact contained in any Registration
Statement (including any final, preliminary or summary Prospectus contained therein or any amendment or supplement thereto) pursuant
to which Registrable Securities were registered under the Securities Act, including all documents incorporated therein by reference,
or any other disclosure document produced by or on behalf of the Company or any of its subsidiaries including reports and other
documents filed under the Exchange Act, or the omission or alleged omission therefrom of a material fact required to be stated
therein or necessary to make the statements therein not misleading, or arising out of or based on any untrue statement or alleged
untrue statement of a material fact contained in any Prospectus (or any amendment or supplement thereto) or the omission or alleged
omission therefrom at such date of a material fact necessary in order to make the statements therein, in the light of the circumstances
under which they were made, not misleading; 

    	 	 17	 

     

    

 

(ii)       against
any and all Liabilities, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation
or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue
statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 5(d) below)
any such settlement is effected with the written consent of the Company, which consent shall not be unreasonably withheld; and

(iii)       against
any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by any indemnified party),
reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any
governmental agency or body, commenced or threatened, or any claim whatsoever arising out of or based upon any such untrue statement
or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under subparagraph
(i) or (ii) above; provided, however, that this indemnity agreement shall not apply to any Liabilities to the extent
arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity
with written information furnished to the Company by the Holder expressly for use in a Registration Statement (or any amendment
thereto) or any Prospectus (or any amendment or supplement thereto).

The indemnity in this Section
5(a) shall be in addition to any liability the Company may otherwise have. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of such Holder or any indemnified party and shall survive any transfer of
such securities by such Holder. The Company shall also indemnify underwriters, selling brokers, dealer managers and similar securities
industry professionals participating in the offering, their officers and directors and each Person who controls such Persons (within
the meaning of the Securities Act and the Exchange Act) to the same extent as provided above with respect to the indemnification
of the indemnified parties. 

(b)       Indemnification
by the Holders. Each Holder severally, but not jointly, agrees to indemnify and hold harmless the Company and the other selling
Holders, and each of their respective officers, directors, partners, employees, representatives and agents, against any and all
Liabilities described in the indemnity contained in Section 5(a) hereof, as incurred, but only with respect to untrue statements
or omissions, or alleged untrue statements or omissions, made in a Registration Statement (or any amendment thereto) or any Prospectus
included therein (or any amendment or supplement thereto) in reliance upon and in conformity with written information such Holder
furnished to the Company by such Holder expressly for use in the Registration Statement (or any amendment thereto) or such Prospectus
(or any amendment or supplement thereto) ; provided, however, that no such Holder shall be liable for any claims
hereunder in excess of the amount of net proceeds received by such Holder from the sale of Registrable Securities pursuant to such
Registration Statement. 

    	 	 18	 

     

    

 

(c)       Notices
of Claims, etc. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of
any action or proceeding commenced against it in respect of which indemnity may be sought hereunder; provided, however,
that failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent
it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have
otherwise than on account of this indemnity agreement. An indemnifying party may participate at its own expense in the defense
of such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the
indemnified party) also be counsel to the indemnified party. Other than in the case of any actual or potential conflict that may
arise from a single counsel representing more than one indemnified party, the indemnifying party or parties shall not be liable
for the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified
parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the
same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified
parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding
by any governmental agency or body, commenced or threatened, or any claim whosoever in respect of which indemnification or contribution
could be sought under this Section 5 (whether or not the indemnified parties are actual or potential parties thereto), unless
such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising
out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act by or on behalf of any indemnified party. 

(d)       Indemnification
Payments. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party
for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated
by Section 5(a)(ii) effected without its written consent if (i) such settlement is entered into more than forty-five (45)
days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice
of the terms of such settlement at least thirty (30) days prior to such settlement being entered into and (iii) such indemnifying
party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

(e)       Contribution.
If the indemnification provided for in this Section 5 is for any reason unavailable to or insufficient to hold harmless an
indemnified party in respect of any Liabilities referred to therein, then each indemnifying party shall contribute to the aggregate
amount of such Liabilities incurred by such indemnified party, as incurred, in such proportion as is appropriate to reflect the
relative fault of the Company, on the one hand, and the Holders, on the other hand, in connection with the acts, statements or
omissions which resulted in such Liabilities, as well as any other relevant equitable considerations.

    	 	 19	 

     

    

 

The relative
fault of the Company on the one hand and the Holders on the other hand shall be determined by reference to, among other things,
whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact
relates to information supplied by the Company or the Holders and the parties’ relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

The Company
and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 5 were determined by
pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to
above in this Section 5. The aggregate amount of Liabilities incurred by an indemnified party and referred to above in this
Section 5 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating,
preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced
or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.
Notwithstanding the provisions of this Section 5(e), no Holder shall be liable for any claims hereunder in excess of the amount
of net proceeds received by such Holder from the sale of Registrable Securities pursuant to any such Registration Statement. 

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.

For purposes
of this Section 5, each Person, if any, who controls a Holder within the meaning of Section 15 of the Securities Act
or Section 20 of the Exchange Act shall have the same rights to contribution as a Holder, and each director of the Company,
and each Person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20
of the Exchange Act shall have the same rights to contribution as the Company.

Section 6.       HOLDBACK AGREEMENT.

(a)       Each
Holder agrees not to effect any sale, transfer, or other actual or pecuniary transfer (including heading and similar arrangements)
of any Registrable Securities or of any other equity securities of the Company, or any securities convertible into or exchangeable
or exercisable for such stock or securities, during the period beginning seven (7) days prior to, and ending sixty (60) days after
(or for such shorter period as to which the managing underwriter(s) may agree), subject to written notice thereof having been given
by the Company to each such Holder prior to the beginning of any such period, the date of the underwriting agreement of each Underwritten
Offering made pursuant to a Registration Statement other than Registrable Securities sold pursuant to such Underwritten Offering,
provided that (i) notwithstanding the foregoing, the duration of the foregoing restrictions shall be no longer than the
duration of the shortest restriction generally imposed by the underwriters on any of the Company, the officers, directors or any
other affiliate of the Company or any other stockholder of the Company on whom a restriction is imposed or with whom the Company
has granted registration rights for any of its equity securities; (ii) the Holders shall not be subject to the foregoing restrictions
if and to the extent that the managing underwriter(s) agree to waive the restriction set forth in such underwriting agreement for
any of the Persons set forth in the immediately preceding clause (i); and (iii) this Section 6(a) shall not apply more than once
in any twelve (12) consecutive month period with respect to any Underwritten Offerings in which the Holders are not permitted to
participate to the extent of their pro rata holdings of Registrable Securities, so long as such Holders did not reduce or eliminate
their participation in any such Underwritten Offerings through their own voluntary decision. Each Holder agrees to enter into any
agreements reasonably requested by any managing underwriter reflecting the terms of this Section 6.

    	 	 20	 

     

    

 

(b)       The
Company agrees not to effect any public sale or distribution of its equity securities (or any securities convertible into or exchangeable
or exercisable for such securities) during the seven (7) days prior to and during the sixty (60)-day period beginning on the effective
date of any underwritten Demand Registration (or for such shorter period as to which the managing underwriter or underwriters may
agree), except as part of such Demand Registration or in connection with any employee benefit or similar plan, any dividend reinvestment
plan, or a business acquisition or combination and to use all reasonable efforts to cause each holder of at least five percent
(5%) (on a fully diluted basis) of its equity securities (or any securities convertible into or exchangeable or exercisable for
such securities) which are or may be purchased from the Company at any time after the date of this Agreement (other than in a registered
offering) to agree not to effect any sale or distribution of any such securities during such period (except as part of such Underwritten
Offering, if otherwise permitted.

Section 7.       TERMINATION.

(a)       Survival.
This Agreement and the rights of each Holder hereunder shall terminate upon the date that all of the Registrable Securities cease
to be Registrable Securities. Notwithstanding the foregoing, the obligations of the parties under Section 5 of this Agreement
shall remain in full force and effect following such time.

Section 8.       MISCELLANEOUS.

(a)       Covenants
Relating To Rule 144. For so long as the Company is subject to the reporting requirements of Section 13 or 15 of the Securities
Act, the Company covenants that it will file the reports required to be filed by it under the Securities Act and Section 13(a)
or 15(d) of the Exchange Act and the rules and regulations adopted by the Commission thereunder. If the Company ceases to be so
required to file such reports, the Company covenants that it will upon the request of any Holder of Registrable Securities (a)
make publicly available such information as is necessary to permit sales pursuant to Rule 144 under the Securities Act, (b) deliver
such information to a prospective purchaser as is necessary to permit sales pursuant to Rule 144A under the Securities Act and
it will take such further action as any Holder of Registrable Securities may reasonably request, and (c) take such further action
that is reasonable in the circumstances, in each case, to the extent required, from time to time, to enable such Holder to sell
its Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (i)
Rule 144 under the Securities Act, as such Rule may be amended from time to time, (ii) Rule 144A under the Securities Act, as such
rule may be amended from time to time, or (iii) any similar rules or regulations hereafter adopted by the Commission. Upon the
request of any Holder of Registrable Securities, the Company will deliver to such Holder a written statement as to whether it has
complied with such requirements and of the Securities Act and the Exchange Act (at any time after it has become subject to the
reporting requirements of the Exchange Act), a copy of the most recent annual and quarterly report(s) of the Company, and such
other reports, documents or stockholder communications of the Company, and take such further actions consistent with this Section 8(a),
as a Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing a Holder to sell any
such Registrable Securities without registration.

and the Holders of a Majority of the Registrable Securities. Any waiver, permit, consent or approval of any kind or character on
the part of any such Holders of any provision or condition of this Agreement must be made in writing and shall be effective only
to the extent specifically set forth in writing. Any amendment or waiver effected in accordance with this paragraph shall be binding
upon each Holder of Registrable Securities and the Company.

(24) hours from delivery if sent to the correct email address and no notice of delivery failure is received, or on receipt of confirmation

(g)       Successors
and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and assigns of the Company. In
addition, the Holders may assign their rights hereunder to subsequent Holders. If any transferee of any Holder shall acquire Registrable
Securities, in any manner, whether by operation of law or otherwise, such Registrable Securities shall be held subject to all of
the terms, and entitled to all of the benefits, of this Agreement, and by taking and holding such Registrable Securities, any such
subsequent Holders shall be conclusively deemed to have agreed to be bound by and to perform all of the terms and provisions of
this Agreement, including the restrictions on resale set forth in this Agreement, and any such subsequent Holder shall be entitled
to receive the benefits hereof.

(h)       Obligations
Limited to Parties to Agreement. Each of the parties hereto covenants, agrees and acknowledges that no Person other than the
Holders and the Company shall have any obligation hereunder and that, notwithstanding that one or more of the Holders may be a
corporation, partnership or limited liability company, no recourse under this Agreement or under any documents or instruments delivered
in connection herewith or therewith shall be had against any former, current or future director, officer, employee, agent, general
or limited partner, manager, member, stockholder or affiliate of any Holder or any former, current or future director, officer,
employee, agent, general or limited partner, manager, member, stockholder or affiliate of any of the foregoing, whether by the
enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any applicable law, it being expressly agreed
and acknowledged that no personal liability whatsoever shall attach to, be imposed on or otherwise by incurred by any former, current
or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or affiliate of any of the
Holders or any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder
or affiliate of any of the foregoing, as such, for any obligations of the Holders under this Agreement or any documents or instruments
delivered in connection herewith or therewith or for any claim based on, in respect of or by reason of such obligation or its creation,
except in each case for any transferee or assignee of a Holder hereunder.

(i)       Specific
Enforcement. Without limiting the remedies available to the Holders, the Company acknowledges that any failure by the Company
to comply with its obligations under Section 2 hereof may result in material irreparable injury to the Holders for which there
is no adequate remedy at law, that it would not be possible to measure damages for such injuries precisely and that, in the event
of any such failure, a Holder may obtain such relief as may be required to specifically enforce the Company’s obligations
under Section 2 hereof.
