REGISTRATION RIGHTS

 

(a)       Demand
Registration.

 

(i)        Request
for Registration. Subject to the limitations and conditions of Section 2(a)(ii), if the Company shall receive from any Holder
or any group of Holders (each a “Requesting Holder,” and collectively, the “Requesting Holders”)
a written demand (the “Demand Notice”), such Demand Notice permitted to be delivered immediately upon the execution
of this Agreement, that the Company effect any Registration (the “Demand Registration”) with respect to all
or a part of the Registrable Securities owned by such Requesting Holder(s) having an estimated aggregate fair market value of at
least $150 million (which demand shall set forth the specified amount of Registrable Securities for which registration is requested
and the intended method of disposition thereof), the Company shall:

 

    	-4-

     

    

(1)       as
promptly as reasonably practicable give written notice of the proposed Registration to all other Holders in accordance with the
terms of Section 2(b);

 

(2)       use
its reasonable best efforts to file a Registration Statement with the Commission in accordance with the request of the Requesting
Holder(s), including without limitation the method of disposition specified therein and covering resales of the Registrable Securities
requested to be registered, as promptly as reasonably practicable but no later than within 30 days of receipt of the Demand Notice;

 

(3)       use
reasonable best efforts to cause such Registration Statement to be declared or become effective as promptly as practicable; and

 

(4)       use
reasonable best efforts to keep such Registration Statement continuously effective and in compliance with the Securities Act and
usable for resale of such Registrable Securities for the period as requested in writing by the Requesting Holder(s) or such longer
period as may be requested in writing by any Holder participating in such Registration (which periods shall be extended to the
extent of any suspensions of sales pursuant to Sections 2(a)(ii)(3));

 

provided, however,
that the Company shall be permitted to file a post-effective amendment or prospectus supplement to any currently effective Shelf
Registration Statement in lieu of an additional Registration Statement pursuant to Section 2(a)(i) to the extent the Company determines,
and the Requesting Holder(s) agree, that the Registrable Securities of the Requesting Holder(s) may be sold thereunder by such
Requesting Holder(s) pursuant to their intended plan of distribution.

 

(ii)       Notwithstanding
anything to the contrary contained herein, the Company shall not be obligated to effect, or take any action to effect, any such
Demand Registration pursuant to this Section 2(a) or to file a post-effective amendment to any Registration Statement or to amend
or supplement any Prospectus in a Registration Statement:

 

(1)       In
any particular jurisdiction in which the Company would be required to execute a general consent to service of process unless the
Company is already subject to service in such jurisdiction, qualify to do business in effecting such Registration, qualification
or compliance or subject itself to taxation on its income in any jurisdiction where it is not then subject to taxation, except
as may be required by the Securities Act or applicable rules or regulations thereunder;

 

(2)       With
respect to securities that are not Registrable Securities;

 

(3)       If
the Company has delivered a certificate by an executive officer of the Company to the Requesting Holders stating that in the good
faith judgment of the Company, it would be materially detrimental to the Company or its security holders for such Registration
to be effected at such time, in which event the Company shall have the right to defer such Registration for a period of not more

 

    	-5-

     

    

than 60 days;
provided, that such right to delay a Registration pursuant to clause (3) shall be exercised by the Company only if
the Company has exercised (or is concurrently exercising) similar black-out rights against holders of similar securities that have
registration rights, if any; or

 

(4)       Solely
with respect to any Affiliate of the Company, during any Scheduled Black-Out Period;

 

provided, that the total
number of days that any such suspension, deferral or delay in Registration pursuant to clauses (3), and (4) in the aggregate may
be in effect in any 365 day period shall not exceed 90 days.

 

(iii)       The
Registration Statement filed pursuant to the request of the Requesting Holder may include shares of Common Stock which are held
by Holders and Persons who, by virtue of agreements with the Company (other than this Agreement), are entitled to include their
securities in any such Registration, if any.

 

(iv)       Underwriting.
If the offering of the Registrable Securities pursuant to such Demand Registration shall be in the form of an underwritten public
offering, the Requesting Holder, in consultation with the Company, shall select one or more investment banking firms of national
standing reasonably acceptable to each to be the Underwriters for the offering. The Company and the Requesting Holder(s) shall
enter into an underwriting agreement in customary form with the managing Underwriter(s).

 

(v)       The
number of Demand Registrations that the Holders shall be entitled to request, and that the Company shall be obligated to undertake,
pursuant to this Section 2(a) shall be five; provided, that the Company shall not be obligated to undertake more than three
underwritten offerings pursuant to this Section 2 during the term of this Agreement, provided, further that in no
event shall the Company be required to effect more than one underwritten offering in any twelve-month period pursuant to this Section
2. No Demand Registration shall count for the purposes of the first clause of the limitations in this Section 2(a)(iv) if the Requesting
Holder(s) determine in good faith to withdraw (within 30 days of making the Demand Registration and in any event prior to the filing
of the Registration Statement or prospectus supplement relating to such request) the proposed Registration, upon written notice
to the Company, due to marketing conditions or regulatory reasons.

 

(vi)       Priority
on Demand Registration. If, in connection with an underwritten Demand Registration, the managing Underwriter(s) give written
advice to the Requesting Holder(s) or the Company of an Underwriters’ Maximum Number, then the Requesting Holders(s) or the
Company, as applicable, shall so advise the Company and all Requesting Holder(s) and the Company will be obligated and required
to include in such Registration only the Underwriters’ Maximum Number, which securities will be so included in the following
order of priority: (i) first, Registrable Securities of the Requesting Holder(s) and the Registrable Securities of any Holder as
agreed to by the Requesting Holder(s), pro rata on the basis of the aggregate number of Registrable Securities owned by all Requesting
Holder(s) who have delivered written requests for

 

    	-6-

     

    

Registration
pursuant to this Section 2 (provided, that if the aggregate number of Registrable Securities of the Requesting Holder(s) to be
included in the Demand Registration is less than 50% of the number requested to be so included by such Requesting Holder(s), the
Requesting Holder(s) may withdraw such Demand Request by giving notice to the Company within three (3) days of receipt of notice
of the number of Registrable Securities of the Requesting Holder to be included; if withdrawn, the Demand Request shall be deemed
not to have been made for all purposes of this Agreement), (ii) second, any shares of Common Stock to be sold by the Company and
(iii) third, any shares of Common Stock requested to be included by Other Shareholders, with priorities among them as the Company
shall so determine to the extent in compliance with such other agreements with the Company.

 

(vii)       In
the case of an underwritten offering under this Section 2(a), the price, underwriting discount and other financial terms for the
Registrable Securities shall be determined by the Requesting Holder(s) in consultation with the Company.

 

(b)        Piggyback
Registration.

 

(i)         If
the Company shall determine to register the offer or sale of any of its capital stock for the account of the Requesting Holder(s)
listed in Section 2(a) pursuant to the terms thereof (each such registration not withdrawn or abandoned prior to the effective
date thereof being herein called a “Piggyback Registration”), the Company will, subject to the conditions set
forth in this Section 2(b):

 

(1)       promptly,
but in any event not less than 15 days prior to filing the applicable Registration Statement, give to each of the Holders a written
notice thereof; and

 

(2)       subject
to Section 2(b)(ii) below and any transfer restrictions any Holder may be a party to, include in such Piggyback Registration (and
any related qualification under blue sky laws or other compliance), and in any underwriting involved therein, all the Registrable
Securities specified in a written request or requests, made by the Holders. Such written request must specify the specific amount
of the Holders’ Registrable Securities for which inclusion is requested and the intended method of disposition thereof and
shall be received by the Company within 15 days after written notice from the Company is given under Section 2(b)(i)(1) above.
In the event that any Holder makes such written request, the Holder may withdraw its Registrable Securities from such Piggyback
Registration by giving written notice to the Company and the managing underwriter, if any, at any time at least two (2) business
days prior to the effective date of the Registration Statement relating to such Piggyback Registration.

 

(ii)       Underwriting.
If the Piggyback Registration of which the Company gives notice is for a registered public offering involving an underwriting,
the Company shall so advise each of the Holders as a part of the written notice given pursuant to Section 2(b)(i)(1) above. In
such event, the right of each of the Holders to a Piggyback Registration pursuant to this Section 2(b) shall be conditioned upon
such Holders’

 

    	-7-

     

    

participation
in such underwriting and the inclusion of such Holders’ Registrable Securities in the underwriting to the extent provided
herein. The Holders whose Registrable Securities are to be included in such Piggyback Registration shall (together with the Company
and any Other Shareholders distributing their securities through such underwriting) enter into an underwriting agreement in customary
form for secondary public offerings with the managing underwriter or underwriters selected for underwriting by the Company (and
if the Registration was initiated by a Holder pursuant to Section 2(a), such underwriters must be selected by the Requesting Holder(s)
and the Company and reasonably acceptable to each other); provided, however, that such underwriting agreement shall
not provide for indemnification or contribution obligations on the part of any Holder or Other Shareholder greater than the obligations
of the Holders under Section 2(h)(ii) or Section 2(h)(iv) except as may be customary and reasonable.

 

(iii)       Priority
on Piggyback Registrations. If a Piggyback Registration is an underwritten registration, and the managing Underwriter(s) shall
give written advice to the Company of an Underwriters’ Maximum Number, the Company will include in such registration only
the Underwriters’ Maximum Number, which securities will be included pro rata on the basis of the aggregate number of shares
owned by each such Person.

 

(c)       Shelf
Registration Statement. Notwithstanding anything to the contrary herein, as soon as reasonably practicable, but in no event
more than 30 days from the date of this Agreement, the Company shall (i) prepare and file with (or confidentially submit to) the
Commission a Shelf Registration Statement that covers all Registrable Securities then outstanding for an offering to be made on
a delayed or continuous basis pursuant to Rule 415 under the Securities Act or any successor rule thereto and (ii) use its commercially
reasonable efforts to cause such Shelf Registration Statement to be declared effective by the Commission as soon as reasonably
practicable thereafter; provided, however, that the Company shall be permitted to file a post-effective amendment
or prospectus supplement to any currently effective Shelf Registration Statement in lieu of an additional Registration Statement
pursuant to Section 2(c) to the extent the Company determines, and the Requesting Holder(s) agree, that the Registrable Securities
of the Requesting Holder(s) may be sold thereunder by such Requesting Holder(s) pursuant to their intended plan of distribution.
From and after the declaration of effectiveness by the Commission of such Shelf Registration Statement or the filing of such post-effective
amendment or prospectus supplement to any currently effective Shelf Registration Statement, the Company shall use commercially
reasonable efforts to cause such Shelf Registration Statement to be continuously effective so long as there are any Registrable
Securities outstanding.

 

In connection with such
Shelf Registration Statement, the Company will, subject to the terms and limitations of this Section 2, as promptly as reasonably
practicable upon notice from any Requesting Holder in accordance with the terms of this Section 2(c), cooperate in any shelf take-down
by amending or supplementing the Prospectus related to such Registration as may be reasonably requested by such Holder or as otherwise
required to reflect the number of Registrable Securities to be sold thereunder. The Company shall not be required to maintain in
effect more than one Shelf Registration at any one time.

 

    	-8-

     

    

(d)       Suspension
of Effectiveness. Notwithstanding anything to the contrary in this Agreement, the Company shall not be obligated to keep a
Registration Statement or a Shelf Registration Statement continuously effective pursuant to Section 2(a)(i)(4) or Section 2(c)
and may suspend the use of the prospectus included therein, if the Company determines in good faith it would be materially detrimental
to the Company or its security holders not to suspend the use of such Registration Statement or Shelf Registration Statement; provided,
however, that the Company shall not be permitted to (i) suspend the use of the Registration Statement or Shelf Registration
Statement, as applicable, for a period exceeding 45 days in succession or (ii) provide a Suspension Notice (as defined below) more
than two (2) times in any twelve (12) month period. In the case of an event that causes the Company to suspend the use of a Registration
Statement or Shelf Registration filed pursuant to the terms herein (a “Suspension Event”), the Company shall
give a certificate by an executive officer of the Company providing notice to the Requesting Holders (a “Suspension Notice”)
to suspend sales of the Registrable Securities and such notice shall represent the basis for the notice and that such suspension
shall continue only for so long as the Suspension Event or its effect is continuing. The Requesting Holders may recommence effecting
sales of the Registrable Securities pursuant to the Registration Statement or Shelf Registration Statement, as applicable, following
further written notice in a certificate by an executive officer of the Company representing to such effect (an “End of
Suspension Notice”) from the Company, which End of Suspension Notice shall be given by the Company to the Requesting
Holders promptly following the conclusion of any Suspension Event or its effect.

 

(e)       Duplicate
Registrations. The Company shall not be required to effect a registration under this Agreement if the Registrable Securities
that are the subject of such request are at the time of such request included in an effective registration statement of the Company
permitting the resale of such Registrable Securities in the manner contemplated by the Requesting Holder.

 

(f)       Expenses
of Registration. Except as otherwise provided in this Agreement, all expenses incurred by the Company incidental to the Company’s
performance of or compliance with this Agreement (the “Registration Expenses”), including (i) all Registration
and filing fees (including (A) with respect to Company filings required to be made with the Commission, all applicable securities
exchanges and/or FINRA and (B) compliance with securities or blue sky laws including any fees and disbursements of counsel for
the underwriter(s) in connection with blue sky qualifications of the Registrable Securities); (ii) word processing, duplicating
and printing expenses; (iii) messenger, telephone and delivery expenses; (iv) fees and disbursements of counsel for the Company;
(v) fees and disbursements of the Company’s independent certified public accountants (including, without limitation,
the fees and disbursements in connection with any “comfort” letters pursuant to Section 2(g)(x)) of this Agreement,
other special experts, retained by the Company, shall be borne by the Company; provided, however, that each Participating
Holder shall bear the underwriting discount or commission relating to the Registrable Securities such Participating Holder sells.  The
Company shall, in any event, pay the expenses of any annual audit or quarterly review, the expenses of any liability insurance
and the expenses and fees for listing the Registrable Securities to be registered on the applicable securities exchange.  Any
other provisions of this Agreement notwithstanding, if a registration request is withdrawn at the request of the Holder(s), then
the Holder(s) responsible for such request shall pay all reasonable Registration Expenses incurred in

 

    	-9-

     

    

connection with such
registration unless the withdrawal of such request is the result of facts or circumstances relating to the Company (based on the
reasonable determination of the Holders) that arise after the date on which such request was made and could reasonably have a material
adverse effect on the offering of the Registrable Securities.

 

(g)       Registration
Procedures. In the case of each Registration effected by the Company subject to this Section 2, the Company will keep the Holders
advised in writing as to the initiation of each Registration and, to the best of knowledge thereof, as to the completion thereof.
At its expense, the Company will:

 

(i)       as
promptly as practicable, prepare and file with the Commission such pre- and post-effective amendments to such Registration Statement,
supplements to the Prospectus and such amendments or supplements to any Issuer Free Writing Prospectus as may be (1) reasonably
requested by the Requesting Holder(s) (if any), (2) reasonably requested by any other Participating Holder (to the extent such
request relates to information relating to such Participating Holder), or (3) necessary to keep such Registration effective for
the period of time required by this Agreement, and comply with provisions of the applicable securities laws with respect to the
sale or other disposition of all securities covered by such Registration Statement during such period in accordance with the intended
method or methods of disposition by the sellers thereof set forth in such Registration Statement;

 

(ii)       notify
the Participating Holders and the managing underwriter or underwriters, if any, and (if requested) confirm such advice in writing
and provide copies of the relevant documents, as promptly as practicable after notice thereof is received by the Company (1) when
the applicable Registration Statement or any amendment thereto has been filed or becomes effective, and when the applicable Prospectus
or Issuer Free Writing Prospectus or any amendment or supplement thereto has been filed, (2) to the extent any of the following
relates to the Participating Holders or information supplied by the Participating Holders, of any written comments by the Commission
or any request by the Commission or any other federal or state governmental authority for amendments or supplements to such Registration
Statement, Prospectus or Issuer Free Writing Prospectus or for additional information, (3) of the issuance by the Commission of
any stop order suspending the effectiveness of such Registration Statement or any order by the Commission or any other regulatory
authority preventing or suspending the use of any Prospectus or any Issuer Free Writing Prospectus or the initiation or threatening
of any proceedings for such purposes and (4) of the receipt by the Company or its legal counsel of any notification with respect
to the suspension of the qualification of the Registrable Securities for offering or sale in any jurisdiction or the initiation
or threatening of any proceeding for such purpose;

 

(iii)       promptly
notify the Participating Holders and the managing underwriter or underwriters, if any, when the Company becomes aware of the happening
of any event as a result of which the applicable Registration Statement, the Prospectus included in such Registration Statement
(as then in effect) or any Issuer Free Writing Prospectus contains any untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary in order to make the statements therein (in the case of such

 

    	-10-

     

    

Prospectus
or any Issuer Free Writing Prospectus, in light of the circumstances under which they were made) not misleading, and when any Issuer
Free Writing Prospectus includes information that may conflict with the information contained in the Registration Statement, or,
if for any other reason the Company shall have determined in good faith it necessary during such time period to amend or supplement
such Registration Statement, Prospectus or Issuer Free Writing Prospectus in order to comply with the Securities Act and, in either
case as promptly as reasonably practicable thereafter, prepare and file with the Commission, and furnish without charge to the
Participating Holders and the managing underwriter or underwriters, if any, an amendment or supplement to such Registration Statement,
Prospectus or Issuer Free Writing Prospectus which shall correct such misstatement or omission or effect such compliance;

 

(iv)       use
its reasonable best efforts to prevent, or obtain the withdrawal of, any stop order or other order suspending the use of any Prospectus
or any Issuer Free Writing Prospectus;

 

(v)       deliver
to each Participating Holder and each underwriter, if any, without charge, as many copies of the applicable Prospectus (including
each preliminary Prospectus), any Issuer Free Writing Prospectus and any amendment or supplement thereto as such Participating
Holder or underwriter may reasonably request (it being understood that the Company consents to the use of such Prospectus, any
Issuer Free Writing Prospectus and any amendment or supplement thereto by such Holder and the underwriters, if any, in connection
with the offering and sale of the Registrable Securities thereby) and such other documents as such Participating Holder or underwriter
may reasonably request in order to facilitate the disposition of the Registrable Securities by such Participating Holder or underwriter;

 

(vi)       subject
to the terms set forth in Section 2(a)(ii)(1) and Section 2(c) hereof, on or prior to the date on which the applicable Registration
Statement is declared effective, use its reasonable best efforts to register or qualify the offer or sale of the Registrable Securities
covered by such Registration Statement under such other securities or blue sky laws of such jurisdictions in the United States
as any Participating Holder reasonably (in light of such Participating Holder’s intended plan of distribution) requests and
do any and all other acts and things that may be reasonably necessary or advisable to enable such Participating Holder to consummate
the disposition of the Registrable Securities owned by such Participating Holder pursuant to such Registration Statement;

 

(vii)       in
connection with an underwritten offering, make such representations and warranties to the Participating Holders and the underwriters
or agents, if any, in form, substance and scope as are customarily made by issuers in underwritten public offerings;

 

(viii)       in
connection with an underwritten offering, enter into such customary agreements (including underwriting and indemnification agreements)
and take such other customary and appropriate actions as the Requesting Holder(s) or the managing underwriter, if any, reasonably
requests in order to expedite or facilitate the Registration and disposition of such Registrable Securities;

 

    	-11-

     

    

(ix)       use
its commercially reasonable efforts to obtain for delivery to the managing underwriter, if any, an opinion or opinions from counsel
for the Company dated the effective date of the Registration Statement or, in the event of an underwritten offering, the date of
the closing under the underwriting agreement, in form and substance as is customarily given to underwriters in an underwritten
secondary public offering;

 

(x)       in
the case of an underwritten offering, use commercially reasonable efforts to obtain for delivery to the Company and the managing
underwriter, if any, a “comfort” letter from the Company’s independent certified public accountants in form and
substance as is customarily given by independent certified public accountants in an underwritten secondary public offering as may
be reasonably requested;

 

(xi)       cooperate
with each Participating Holder and the underwriters, if any, of such Registrable Securities and their respective counsel in connection
with any filings required to be made with FINRA;

 

(xii)       use
its commercially reasonable efforts to cause all Registrable Securities covered by the applicable Registration Statement to be
listed or quoted on a national securities exchange or trading system and each securities exchange and trading system (if any) on
which similar securities issued by the Company are then listed;

 

(xiii)       cooperate
with the Participating Holders and the underwriters, if any, to facilitate the timely preparation and delivery of certificates
(or non-physical certificates, such as through the use of The Depositary Trust Company’s Direct Registration System), with
requisite CUSIP numbers, representing Registrable Securities to be sold and not bearing any restrictive legends;

 

(xiv)       in
the case of an underwritten offering, make reasonably available the appropriate executives and members of management of the Company

in any such underwritten offering and otherwise to facilitate, cooperate with, and participate in each proposed offering contemplated
herein and customary selling efforts related thereto;

 

(xv)       use
its commercially reasonable efforts to procure the cooperation of the Company’s transfer agent in settling any offering or
sale of Registrable Securities, including with respect to the transfer of physical security instruments into book-entry form in

(xvi)       use
its commercially reasonable efforts to take such actions as are under its control to remain a well-known seasoned issuer (as such
term in defined in Rule 405 under the Securities Act) and not become an ineligible issuer (as such term is defined in Rule 405
under the Securities Act) during the period when such Registration Statement remains in effect; and

 

(xvii)       in
connection with an underwritten offering, make available for inspection by a representative of Participating Holders that are selling
at least ten percent (10%) of 

 

    	-12-

     

    

the
Registrable Securities included in such Registration (and who is named in the applicable prospectus supplement as a Person who
may be deemed to be an underwriter with respect to an offering and sale of Registrable Securities), the managing underwriter(s),
if any, and any attorneys or accountants retained by such Holders or the managing underwriters(s), at the offices where normally
kept, during reasonable business hours, financial and other records and pertinent corporate documents of the Company, and cause
the officers, directors and employees of the Company to supply all information in each case reasonably requested by any such representative,
managing underwriter, attorney or accountant in connection with such Registration Statement, in each case as shall be advisable
to conduct a reasonable investigation within the meaning of the Securities Act; provided, that if any such information is
identified by the Company as being confidential or proprietary, each Person receiving such information shall take such actions
as are reasonably necessary to protect the confidentiality of such information and shall sign customary confidentiality agreements
reasonably requested by the Company prior to the receipt of such information.

 

(h)       Indemnification.

 

(i)       Indemnification
by the Company. With respect to each Demand Registration or Piggyback Registration which has been effected pursuant to this
Section 2, the Company agrees to indemnify and hold harmless, to the fullest extent permitted by law, (1) each of the Participating
Holders and each of its officers, directors, limited or general partners and members thereof, (2) each member, limited or
general partner of each such member, limited or general partner, (3) each of their respective Affiliates, officers, directors,
shareholders, employees, advisors, and agents and each Person who controls (within the meaning of the Securities Act or the Exchange
Act) such Persons and each underwriter, if any, and each Person who controls (within the meaning of the Securities Act or the Exchange
Act) any underwriter, against any and all claims, losses, damages, penalties, judgments, suits, costs, liabilities, reasonable
attorney’s fees and reasonable documented out of pocket expenses of investigating and defending a claim (or actions in respect
thereof) (collectively, the “Losses”) arising out of or based on (A) any untrue statement (or alleged untrue
statement) of a material fact contained in any Registration Statement (including any Prospectus or Issuer Free Writing Prospectus)
or any other document incident to any such Demand Registration or Piggyback Registration, qualification or compliance, (B) any
omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements
therein not misleading (in the case of any Prospectus or Issuer Free Writing Prospectus, in light of the circumstances under which
they were made not misleading), or (C) any violation by the Company of the Securities Act, the Exchange Act or blue sky laws applicable
to the Company and relating to action or inaction required of the Company in connection with any such Demand Registration or Piggyback
Registration, qualification or compliance, and will reimburse each of the Persons listed above, for any reasonable and documented
legal and any other expenses reasonably incurred in connection with investigating and defending any such Losses, provided,
that the Company will not be liable in any such case to the extent that any such Losses arise out of or are based on any untrue
statement or omission of material fact based upon written information furnished to the Company by the Participating Holders or
underwriter and stated to be specifically for use therein. The

 

    	-13-

     

    

liability imposed
by this Section 2(h)(i) will be in addition to any liability which the Company may otherwise have.

 

(ii)       Indemnification
by the Participating Holders. Each of the Participating Holders agrees (severally and not jointly) to indemnify and hold harmless,
to the fullest extent permitted by law, the Company, each of its directors and officers and each underwriter, if any, of the Company’s
securities covered by such a Registration Statement, each Person who controls the Company (within the meaning of the Securities
Act or the Exchange Act) or such underwriter, each other Participating Holder and each of their respective officers, directors,
partners and members, and each Person controlling such other Participating Holder (within the meaning of the Securities Act or
the Exchange Act) against any and all Losses arising out of or based on (A) any untrue statement (or alleged untrue statement)
of a material fact contained in any Registration Statement (including any Prospectus or Issuer Free Writing Prospectus) or any
other document incident to any such Demand Registration or Piggyback Registration, qualification or compliance (including any notification
or the like) made by such Participating Holder in writing or (B) any omission (or alleged omission) to state therein a material
fact required to be stated therein or necessary to make the statements by such Participating Holder therein not misleading (in
the case of any Prospectus or Issuer Free Writing Prospectus, in light of the circumstances under which they were made not misleading)
and will reimburse the Persons listed above for any reasonable and documented legal or any other expenses reasonably incurred in
connection with investigating or defending any such Losses, in each case to the extent, but only to the extent, that such untrue
statement (or alleged untrue statement) or omission (or alleged omission) is made in reliance upon and in conformity with written
information furnished to the Company by such Participating Holder and stated to be specifically for use therein; provided,
however, that the obligations of each of the Participating Holders hereunder shall be limited to an amount equal to the
net proceeds (after giving effect to any underwriters discounts and commissions) such Participating Holder receives in such Demand
Registration or Piggyback Registration. The liability imposed by this Section 2(h)(i) will be in addition to any liability which
the Participating Holders may otherwise have.

 

(iii)       Conduct
of the Indemnification Proceedings. Each party entitled to indemnification under this Section 2(h) (the “Indemnified
Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”)
promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the
Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided, that counsel
for the Indemnifying Party, who shall conduct the defense of such claim or any litigation resulting therefrom, shall be approved
by the Indemnified Party (whose approval shall not unreasonably be withheld) and the Indemnified Party may participate in such
defense at such party’s expense (unless the Indemnified Party shall have reasonably concluded that there may be a conflict
of interest between the Indemnifying Party and the Indemnified Party in such action, in which case the fees and expenses of counsel
shall be at the expense of the Indemnifying Party), and provided, further, that the failure of any Indemnified Party
to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this

 

    	-14-

     

    

Section 2(h)
except to the extent the Indemnifying Party is prejudiced thereby. It is understood and agreed that the Indemnifying Party shall
not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more
than one separate legal counsel for all Indemnified Parties; provided, however, that where the failure to be provided
separate legal counsel could potentially result in a conflict of interest on the part of such legal counsel for all Indemnified
Parties, separate counsel shall be appointed for Indemnified Parties to the extent needed to alleviate such potential conflict
of interest. No Indemnifying Party, in the defense of any such claim or litigation shall, except with the prior written consent
of each Indemnified Party, consent to entry of any judgment or enter into any settlement which faults the actions of the Indemnified
Party or fails to include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of
a release from all liability in respect to such claim or litigation. Each Indemnified Party shall furnish such information regarding
itself or the claim in question as an Indemnifying Party may reasonably request in writing and as shall be reasonably required
in connection with the defense of such claim and litigation resulting therefrom.

 

(iv)       If
the indemnification provided for in this Section 2(h) is held by a court of competent jurisdiction to be unavailable to an Indemnified
Party with respect to any Losses, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall
contribute to the amount paid or payable by such Indemnified Party as a result of such Losses in such proportion as is appropriate
to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection
with the statements or omissions (or alleged statements or omissions) which resulted in such Losses, as well as any other relevant
equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference
to, among other things, whether the untrue (or alleged untrue) statement of a material fact or the omission (or alleged omission)
to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and the parties’
relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; provided,
however, that the obligations of each of the Participating Holders hereunder shall be several and not joint and shall be
limited to an amount equal to the net proceeds (after giving effect to any underwriters discounts and commissions) such Participating
Holder receives in such Demand Registration or Piggyback Registration and, provided, further, that 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 2(h)(iv), each Person, if any,
who controls an underwriter or agent within the meaning of Section 15 of the Securities Act shall have the same rights to contribution
as such underwriter or agent and each director of the Company, each officer of the Company who signed a Registration Statement,
and each Person, if any, who controls the Company or a selling Holder within the meaning of Section 15 of the Securities Act shall
have the same rights to contribution as the Company or such selling Holder, as the case may be.

 

(v)       Subject
to the limitations on the Holders’ liability set forth in Section 2(h)(ii) and Section 2(h)(iv), the remedies provided for
in this Section 2(h) are not

 

    	-15-

     

    

exclusive and
shall not limit any rights or remedies which may otherwise be available to any Indemnified Party at law or equity. The remedies
shall remain in full force and effect regardless of any investigation made by or on behalf of such Holder or any Indemnified Party
and survive the transfer of such securities by such Holder.

 

(vi)       The
obligations of the Company and of the Participating Holders hereunder to indemnify any underwriter or agent who participates in
an offering (or any Person, if any, controlling such underwriter or agent within the meaning of Section 15 of the Securities Act)
shall be conditioned upon the underwriting or agency agreement with such underwriter or agent containing an agreement by such underwriter
or agent to indemnify and hold harmless the Company, each of its directors and officers, each other Participating Holder, and each
Person who controls the Company (within the meaning of the Securities Act or the Exchange Act) or such Participating Holder against
all Losses, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration
Statement (or any amendment thereto), or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto)
in reliance upon and in conformity with written information furnished to the Company by such underwriter or agent expressly for
use in such filings described in this sentence.

 

(i)       Participating
Holders.

 

(i)       Each
of the Participating Holders shall furnish to the Company such information regarding such Participating Holder and its partners
and members, and the distribution proposed by such Participating Holder as the Company may reasonably request in writing and as
shall be reasonably requested in connection with any Registration, qualification or compliance referred to in this Section 2.

 

(ii)       In
the event that, either immediately prior to or subsequent to the effectiveness of any Registration Statement, any Participating
Holder shall distribute Registrable Securities to its partners or members, such Participating Holder shall so advise the Company
promptly and provide such information as shall be necessary to permit an amendment to such Registration Statement to provide information
with respect to such partners or members, as selling security holders. As soon as is reasonably practicable following receipt of
such information, the Company shall file an appropriate amendment to such Registration Statement reflecting the information so
provided. Any incremental expense to the Company resulting from such amendment shall be borne by such Participating Holder.

 

(iii)       Each
Holder agrees that at the time that such Holder is a Participating Holder, upon receipt of any notice from the Company of the happening
of any event of the kind described in Section 2(g)(iii), such Holder shall forthwith discontinue disposition of Registrable Securities
pursuant to the Registration Statement covering such Registrable Securities until such Holder’s receipt of the copies of
a supplemented or amended Prospectus or Issuer Free Writing Prospectus or until such Holder is advised in writing by the Company
that the use of the Prospectus or Issuer Free Writing Prospectus, as the case may be, may be resumed, and, if so directed by the
Company, such Holder shall deliver to the Company all copies, other than any permanent file copies then in such

 

    	-16-

     

    

Holder’s
possession, of the most recent Prospectus or any Issuer Free Writing Prospectus covering such Registrable Securities at the time
of receipt of such notice. If the Company shall give such notice, the Company shall extend the period during which such Registration
Statement shall be maintained effective by the number of days during the period from and including the date of the giving of notice
pursuant to Section 2(g)(iii) to the date when the Company shall make available to such Holder a copy of the supplement or amended
Prospectus or Issuer Free Writing Prospectus or is advised in writing that the use of the Prospectus or Issuer Free Writing Prospectus
may be resumed.

 

(j)       Rule
144. With a view to making available the benefits of certain rules and regulations of the Commission which may permit the sale
of restricted securities to the public without registration, the Company agrees to use its reasonable best efforts to file with
the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange
Act at any time during which it is subject to such reporting requirements (or, if the Company is not required to file such reports,
it will, upon the request of the Holders holding a majority of the then outstanding Registrable Securities, make publicly available
such necessary information to permit sales pursuant to Rules 144 under the Securities Act).

 

(k)       Termination.
The Registration Rights set forth in this Section 2 shall terminate and cease to be available as to any securities held by a Holder
at such time as such Holder (after owning) first ceases to own any Registrable Securities.

 

(l)       Notwithstanding
any provision of this Agreement to the contrary, in order for a Registration to be included as a Registration for purposes of this
Section 2, the Registration Statement in connection therewith shall have been continually effective in compliance with the Securities
Act and usable for resale for the full period established with respect to such Registration (except in the case of any suspension
of sales pursuant to (A) a Scheduled Black-Out Period, or (B) Section 2(g)(iii) hereof, in which case such period shall be extended
to the extent of such suspension).

 

(m)       Notwithstanding
any provision of this Agreement to the contrary, if the Company is required to file a post-effective amendment to a Registration
Statement to incorporate the Company’s quarterly and annual reports and related financial statements on Form 10-Q and Form
10-K, the Company shall use its reasonable best efforts to promptly file such post-effective amendment and may postpone or suspend
effectiveness of such Registration Statement to the extent the Company determines necessary to comply with applicable securities
laws; provided, that the period by which the Company postpones or suspends the effectiveness of a shelf Registration Statement
pursuant to this Section 2(m) plus any suspension, deferral or delay pursuant to Section 2(g)(iii) shall not exceed 60 days in
the aggregate in any twelve-month period.

SECTION
3.

MISCELLANEOUS

 

(a)       Governing
Law; Jurisdiction. This Agreement shall be governed by and construed in accordance with the laws of the State of New York without
reference to conflict of laws principles. Each of the Holders and the Company (a) irrevocably and unconditionally agrees that any
legal action or proceeding based on or arising out of this Agreement will be brought exclusively in the U.S. District Court for

city of New York, New York County), (b) irrevocably waives the right to trial by jury in any such action or proceeding, (c) irrevocably
submits to the personal jurisdiction and venue of the aforesaid courts and irrevocably waives any argument that such courts are

(b)       Section

Each Holder agrees that any notice received
pursuant to this Agreement, including any notice of a proposed underwritten public offering or postponement of an offering or effecting
of a registration, may be confidential information and that any trading in securities of the Company following receipt of such
information may only be done in compliance with all applicable securities laws.

 

(d)       Reproduction
of Documents. This Agreement and all documents relating thereto, including, without limitation, any consents, waivers and modifications
which may hereafter be executed, may be reproduced by the Holders by any photographic, photostatic, microfilm, microcard, miniature
photographic or other similar process and the Holders may destroy any original document so reproduced. The parties hereto agree
and stipulate that any such reproduction shall be admissible in evidence as the original itself in any judicial or administrative
proceeding (whether or not the original is in existence and whether or not such reproduction was made by the Holders in the regular
course of business) and that any enlargement, facsimile or further reproduction of such reproduction shall likewise be admissible
in evidence.

 

(e)       Successors
and Assigns. Neither this Agreement nor any right or obligation hereunder may be assigned in whole or in part by any party
without the prior written consent of the other parties hereto and any purported assignment in violation of this provision shall
be void; provided, however, that the rights and obligations hereunder of any Holder may be assigned, in whole or
in part, to any Person who acquires such Registrable Securities that (i) is an Affiliate of any Holder or (ii) is unable to immediately
sell, without limitations (including, but not limited to, any limitation on volume or manner of sale) or restrictions under Rule
144, all Registrable Securities and other shares of Common Stock held by such Person (provided, that for this clause (ii),
any such rights and obligations may be assigned solely with respect to such Registrable Securities) (each such Person described
in clauses (i) or (ii) a “Permitted Assignee”).

 

    	-19-

     

    

Any assignment pursuant
to this Section 3(e) shall be effective and any Person shall become a Permitted Assignee only upon receipt by the Company of (1)
a written notice from the transferring Holder stating the name and address of the transferee and identifying the number of shares
of Registrable Securities with respect to which the rights under this Agreement are being transferred and, if fewer than all of
the rights attributable to a Holder hereunder are to be so transferred, the nature of the rights so transferred and (2) a written
instrument by which the transferee agrees to be bound by all of the terms and conditions applicable to a Holder of such Registrable
Securities. Subject to the foregoing, this Agreement shall inure to the benefit of and be binding upon the successors and permitted
assigns of each of the parties.

 

(f)       Several
Nature of Commitments. The obligations of each Holder hereunder are several and not joint, and relate only to the Registrable
Securities held by such Holder from time to time. No Holder shall bear responsibility to the Company for breach of this Agreement
or any information provided by any other Holder.

 

(g)       Entire
Agreement; Amendment and Waiver. This Agreement constitutes the entire understanding of the parties hereto relating to the
subject matter hereof and supersedes all prior understandings among such parties. This Agreement may be amended with (and only
with) the written consent of the Company and the Holders holding a majority of the then outstanding Registrable Securities and
any such amendment shall apply to all Holders and all of their Registrable Securities; provided, however, that, notwithstanding
the foregoing, no amendment to this Agreement may adversely affect the rights of a Holder hereunder without the prior written consent
of such Holder; provided, further, that, notwithstanding the foregoing, additional Holders may become party hereto
upon an assignment of rights and obligations hereunder pursuant to Section 3(e); provided further, however, that
other than as set forth in Section 3(e), the Company may not add additional parties hereto without the consent of Holders holding
a majority of the then outstanding Registrable Securities. The observance of any term of this Agreement may be waived by the party
or parties waiving any rights hereunder.

 

(h)       Injunctive
Relief.  It is hereby agreed and acknowledged by each Holder and the Company that irreparable injury to each would occur
in the event that any provisions of this Agreement were not performed in accordance with their specific terms or were otherwise
breached and that money damages are not an adequate remedy for such a breach.  It is accordingly agreed that each Holder and
the Company may be entitled to specific performance of, and injunctive relief to prevent any violation of, the terms hereof. The
Holders and the Company agree to waive any bonding requirement under any applicable law in the case any other party seeks to enforce
the terms by way of equitable relief.

 

(i)       Other
Registration Rights. The Company is not currently a party to any agreement with any holder or prospective holder of any securities
of the Company giving such holder or prospective holder any registration rights the terms of which are on parity with or senior
to, or inconsistent with, the registration rights granted to the Holders pursuant to this Agreement. The Company shall not enter
into any registration rights agreement that is inconsistent with or violates the rights granted to the Holders by this Agreement.

 

(j)       Severability.
If at any time subsequent to the date hereof, any provision of this Agreement shall be held by any court of competent jurisdiction
to be illegal, void or

 

    	-20-

     

    

unenforceable, such provision
shall be of no force or effect, but the illegality or unenforceability of such provision shall have no effect upon the legality
or enforceability of any other provision of this Agreement.

 

(k)       Counterparts.
This Agreement may be executed in two or more counterparts, each of which will be considered one and the same agreement and will
become effective when counterparts have been signed by each of the Parties and delivered to the other Party (including by means

(l)       Interpretation
of this Agreement. When a reference is made in this Agreement to a Section, such reference shall be to a Section of this Agreement,
unless otherwise indicated. The headings contained in this Agreement are for reference purposes only and shall not affect in any
way the meaning or interpretation of this Agreement. Whenever the words “include,” “includes” and “including”
are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof,
“herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement
as a whole and not to any particular provision of this Agreement. The word “will” shall be construed to have the same
meaning as the word “shall.” The definitions contained in this Agreement are applicable to the singular as well as
the plural forms of such terms. Any agreement, instrument, law, rule or statute defined or referred to herein means, unless otherwise
indicated, such agreement, instrument, law, rule or statute as from time to time amended, modified or supplemented. Each of the
parties acknowledges that it has been represented by counsel of its choice throughout all negotiations that have preceded the execution
of this Agreement, and that it has executed the same with the advice of said independent counsel. Each party cooperated and participated
in the drafting and preparation of this Agreement and the documents referred to herein, and any and all drafts relating thereto
exchanged among the parties shall be deemed the work product of all of the parties and may not be construed against any party by
reason of its drafting or preparation. Accordingly, any rule of law or any legal decision that would require interpretation of
any ambiguities in this Agreement against any party that drafted or prepared it is of no application and is hereby expressly waived
by each of the parties, and any controversy over interpretations of this Agreement shall be decided without regards to events of
drafting or preparation.
