or its capacity as a stockholder, director, member of a board committee, officer of the Company or otherwise) hereby agree to
take such actions as may be necessary or desirable within his, her or its control (including, in the case of a Stockholder,
by voting all voting securities (including all voting Shares) owned by such Stockholder or over which such Stockholder has
voting control) to ensure the election or appointment of such designee to fill such vacancy on the Board to the fullest
extent permitted by Applicable Law. In the event that the FTP Investors shall fail to designate in writing a representative

after notice from the Company to the FTP Investors with respect to such failure, then the vacant position shall be filled by
an individual designated by the FTP Investor Directors then in office; provided, that such individual shall be removed
from such position if the FTP Investors so direct and simultaneously designate a new FTP Investor Director.

such postponement has been given to the Directors.

ARTICLE
III

PRE-EMPTIVE
RIGHTS

 

Section
3.01 Pre-emptive Right.

 

(a) Issuance
of New Securities. If the Board desires to cause the Company to issue New Securities, whether for cash or any other
consideration, other than an issuance of New Securities described in clause (A), (B), (C) or (D) of Section 2.04(vii), so
long as the FTP Investors beneficially own, in the aggregate, not less than ten percent (10%) of the issued and outstanding
Common Stock, the FTP Investors shall have the first right (in such a case, the “Pre-emptive
Stockholders”) to acquire up to the amount of New Securities that is necessary to ensure that the FTP
Investors’ Common Percentage after giving effect to the issuance of such New Securities is not less than the FTP
Investors’ Common Percentage immediately prior to the issuance of such New Securities (the “Pre-emptive
Portion”).

 

(b) Additional
Issuance Notices. The Company shall give written notice (an “Issuance Notice”) of any proposed
issuance or sale of New Securities described in Section 3.01(a) to the Pre-emptive Stockholder within five (5)
Business Days following any meeting of the Board at which any such issuance or sale is approved. The Issuance Notice shall,
if applicable, be accompanied by a written offer from any prospective purchaser seeking to purchase the applicable New
Securities (a “Prospective Purchaser”) and shall set forth the material terms and conditions of the
proposed issuance or sale, including:

 

(i)
the number and description of New Securities proposed to be issued;

 

(ii)
the proposed issuance date, which shall be at least ten (10) Business Days from the date of the Issuance Notice;

 

(iii)
the proposed purchase price per share of New Securities and all other material terms of the offer or sale; and

 

(iv) 
if the consideration to be paid by the Prospective Purchaser includes non-cash consideration, the Fair Market Value
thereof.

 

    	 	 13	 

     

    

 

(c) Exercise
of Pre-emptive Rights. The Pre-emptive Stockholders shall for a period of five (5) Business Days following the receipt
of an Issuance Notice (the “Pre-emptive Exercise Period”) have the right to elect irrevocably to purchase
all or any portion of their Pre-emptive Portion of any New Securities on the terms and conditions, including, the purchase
price, set forth in the Issuance Notice by delivering a written notice to the Company (a “Pre-emptive Acceptance
Notice”) specifying the number of New Securities they desire to purchase up to their Pre-emptive Portion. The
delivery of a Pre-emptive Acceptance Notice by the Pre-emptive Stockholders shall be a binding and irrevocable offer by such
Pre-emptive Stockholders to purchase the New Securities described therein, allocated among them as they may agree. The
failure of the Pre-emptive Stockholders to deliver a Pre-emptive Acceptance Notice by the end of the Pre-emptive Exercise
Period shall constitute a waiver of their rights under this Section 3.01(c) with respect to the purchase of such New
Securities, but shall not affect their rights with respect to any future issuances or sales of New Securities.

 

(d) Sales
to the Prospective Purchaser. Following the expiration of the Pre-emptive Exercise Period, the Company shall be free to
complete the proposed issuance or sale of New Securities described in the Issuance Notice with respect to which the
Pre-emptive Stockholders declined to exercise the pre-emptive right set forth in this Section 3.01 on terms no less
favorable to the Company than those set forth in the Issuance Notice (except that the amount of New Securities to be issued
or sold by the Company may be reduced); provided, that: (i) such issuance or sale is closed within twenty (20)
Business Days after the expiration of the Pre-emptive Exercise Period (subject to the extension of such twenty (20) Business
Day period for a reasonable time not to exceed forty (40) Business Days to the extent reasonably necessary to obtain any
third-party approvals); and (ii) for the avoidance of doubt, the price at which the New Securities are sold to the
Prospective Purchaser is at least equal to or higher than the purchase price described in the Issuance Notice. In the event
the Company has not sold such New Securities within such time period, the Company shall not thereafter issue or sell any New
Securities without first again offering such securities to the Pre-emptive Stockholders in accordance with the procedures set
forth in this Section 3.01.

 

(e) Closing
of the Issuance. The closing of any purchase by any Pre-emptive Stockholder shall be consummated concurrently with the
consummation of the issuance or sale described in the Issuance Notice. Upon the issuance or sale of any New Securities in
accordance with this Section 3.01, the Company shall deliver, or cause to be delivered, the New Securities in
certificated form, free and clear of any liens (other than those arising hereunder and those attributable to the actions of
the purchasers thereof), and the Company shall so represent and warrant to the purchasers thereof, and further represent and
warrant to such purchasers that such New Securities shall be, upon issuance thereof to such purchasers and after payment
therefor, duly authorized, validly issued, fully paid and non-assessable. Each Pre-emptive Stockholder shall deliver to the
Company the purchase price for the New Securities purchased by it by certified or bank check or wire transfer of immediately
available funds. Each party to the purchase and sale of New Securities shall take all such other actions as may be reasonably
necessary to consummate the purchase and sale, including, without limitation, entering into such additional agreements as may
be necessary or appropriate.

 

    	 	 14	 

     

    

 

(f)
Underwritten Public Offering. Notwithstanding anything in this Article III to the contrary, in the event that any issuance of
New Securities is to be made pursuant to an underwritten Public Offering, the Pre-emptive Stockholders shall have the right
to purchase up to their Pre-emptive Portion in accordance with the following procedures. Upon approval by the Board of the
commencement of an underwritten Public Offering by the Company (which approval shall set forth the proposed size of the
underwritten Public Offering, the New Securities to be offered and an estimate (which may be based upon a midpoint of a
range) of the offering price) and delivery by the Company of notice to the Pre-emptive Stockholders of such Board approval
and related information, the Pre-emptive Stockholders shall elect within three (3) Business Days of delivery of such notice
to purchase up to their Pre-emptive Portion of such Public Offering based upon the terms approved by the Board by delivery of
a written notice back to the Company within such three (3) Business Day period. The Pre-emptive Stockholders may revoke such
election to purchase if (i) the non-pricing terms of any agreements proposed to be entered into by the Pre-emptive
Stockholders in connection with the underwritten Public Offering are not commercially reasonable or would adversely affect
the liquidity of the Shares beneficially owned by the Pre-emptive Stockholders or (ii) the pricing of such New Securities
offered by the underwriters in connection with such underwritten Public Offering is less than 95% of, or greater than 105%
of, the estimated price previously approved by the Board (in which event the Pre-emptive Stockholders may elect to reduce or
eliminate their purchase of New Securities entirely in connection with the underwritten Public Offering).

 

(g)
Termination. This Section 3.01, and the covenants contained herein, shall terminate upon the earliest to occur of (i)
the FTP Investors’ beneficial ownership of Common Stock is, in the aggregate, less than ten percent (10%) of the issued
and outstanding Common Stock (on a Fully Diluted Basis and, for the avoidance of doubt, including options that are not yet
vested) or (ii) a Change of Control.

are:

 

(i)
permitted by and made in accordance with Section 4.02; or

 

(ii)
are made by a Tag-along Stockholder upon the exercise of its tag-along right pursuant to Section 4.04 after the
Applicable ROFR Rightholders have declined to exercise their rights in full under this Section 4.03.

 

(c)
Offer Notice.

 

(i)
The Offering Stockholder shall, within five (5) Business Days of receipt of the Transfer Offer, give written notice (a
“ROFR Notice”) to the Company and each Applicable ROFR Rightholder stating that it has received a Transfer
Offer for the Offered Stock and specifying:

 

		(A)	the
                                         class(es) or series and the applicable aggregate number of shares of Offered Stock to
                                         be Transferred by the Offering Stockholder;

 

    	 	 17	 

     

    

 

		(B)	the
                                         proposed date, time and location of the closing of the Transfer, which shall not be less
                                         than thirty (30) Business Days from the date of the ROFR Notice;
	 	 	 
		(C)	the
                                         purchase price per share for each applicable class or series of Offered Stock (which
                                         shall be payable solely in cash) and the other material terms and conditions of the Transfer
                                         Offer; and

                                         name of the Prospective Transferee who has offered to purchase such Offered Stock.

 

For
the avoidance of doubt, in the event of a Transfer Offer involving more than one class or series of Offered Stock, the Offering
Stockholder may deliver a single ROFR Notice to the Company and each Applicable ROFR Rightholder.

 

(ii)
The ROFR Notice shall constitute the Offering Stockholder’s offer to Transfer all of the Offered Stock to the
Applicable ROFR Rightholders in accordance with the provisions of this Section 4.03, which offer shall be irrevocable

                                         in the ROFR Notice;
	 	 	 
		(B)	the
                                         Offering Stockholder has all the necessary power and authority and has taken all necessary

                                         this Section 4.03; and
	 	 	 
		(C)	the
                                         Offered Stock described in the ROFR Notice is free and clear of any and all liens other
                                         than those arising as a result of or under the terms of this Agreement.

elections made under this Section 4.03(d), no less than all of each class or series of Offered Stock will be purchased
by the Applicable ROFR Rightholders.

 

    	 	 18	 

     

    

 

(ii)
For a period of ten (10) Business Days following the receipt of a ROFR Notice (such period, the “Applicable ROFR
Rightholder Option Period”), each Applicable ROFR Rightholder shall have the right to elect to purchase all (but
not less than all) of its ROFR Pro Rata Portion of each class or series of Offered Stock by delivering a written notice to
the Company and the Offering Stockholder (an “Applicable ROFR Rightholder Exercise Notice”) specifying its
desire to purchase its ROFR Pro Rata Portion of each class or series of Offered Stock, on the terms and applicable purchase
price(s) set forth in the ROFR Notice. The Applicable ROFR Rightholder Exercise Notice shall be binding upon delivery and
irrevocable by the Applicable ROFR Rightholder.

 

(iii)
If the Applicable ROFR Rightholders pursuant to Section 4.03(d)(ii) do not, in the aggregate, elect to purchase all of
the Offered Stock, each Applicable ROFR Rightholder electing pursuant to Section 4.03(d)(ii) to purchase its entire
ROFR Pro Rata Portion of each class or series of remaining Offered Stock (each, an “Exercising Applicable ROFR
Rightholder”) shall have the right to purchase all or any portion of any class or series of remaining Offered Stock
not elected to be purchased by the Applicable ROFR Rightholders. As promptly as practicable following the Applicable ROFR
Rightholder Exercise Period, the Offering Stockholder shall deliver a written notice to each Exercising Applicable ROFR

(iv)
The failure of any Applicable ROFR Rightholder to deliver an Applicable ROFR Rightholder Exercise Notice by the end of the
Applicable ROFR Rightholder Option Period or the Exercising Applicable ROFR Rightholder Option Period, as applicable, shall
constitute a waiver of the applicable rights of first refusal under this Section 4.03 with respect to the Transfer of
the Offered Stock, but shall not affect their respective rights with respect to any future Transfers.

 

(e) Allocation
of Offered Stock. Upon the expiration of the Applicable ROFR Rightholder Option Period or, if applicable, the expiration

the balance, if any, not allocated under clause (i) above shall be allocated to those Exercising Applicable ROFR Rightholders
electing pursuant to Section 4.03(d)(iii) to purchase a number of remaining Offered Stock exceeding their respective ROFR
Pro Rata Portions, in an amount, with respect to each such Exercising Applicable ROFR Rightholder, that is equal to the lesser
of:

 

		(A)	the
                                         number of such class or series of remaining Offered Stock that such Exercising Applicable
                                         ROFR Rightholder elected to purchase in excess of its applicable ROFR Pro Rata Portion;
                                         and
	 	 	 
		(B)	the
                                         product of (1) the number of each class or series of remaining Offered Stock not allocated
                                         under Section 4.03(e)(i) multiplied by (2) a fraction, the numerator of which
                                         is the number of such class or series of remaining Offered Stock that such Exercising
                                         Applicable ROFR Rightholder was permitted to purchase pursuant to Section 4.03(e)(i),
                                         and the denominator of which is the aggregate number of such class or series of remaining
                                         Offered Stock that all Exercising Applicable ROFR Rightholders were permitted to purchase
                                         pursuant to Section 4.03(e)(i);

 

provided,
that if following the allocation under this Section 4.03(e)(ii) there are any remaining unallocated shares of and class
or series of remaining Offered Stock, those shares shall be allocated to those Exercising Applicable ROFR Rightholders who have
not yet been allocated their full share election of such class or series made pursuant to Section 4.03(d)(iii) pro rata
based on the number of remaining shares of such class or series elected to be purchased by those Exercising Applicable ROFR Rightholders
until no Offered Stock remains.

 

(f)
Consummation of Sale to the Applicable ROFR Rightholders. In the event that the Applicable ROFR Rightholders shall have,
in the aggregate, exercised their respective rights to purchase all and not less than all of the Offered Stock, then the Offering
Stockholder shall sell such Offered Stock to the Applicable ROFR Rightholders, and the Applicable ROFR Rightholders, as the case
may be, shall purchase such Offered Stock, within sixty (60) days following the expiration of the Applicable ROFR Rightholder
Option Period or, if applicable, the Exercising Applicable ROFR Rightholder Option Period (either of which period may be extended
for a reasonable time not to exceed ninety (90) days to the extent reasonably necessary to obtain required approvals or consents
from any Governmental Authority). Each Stockholder shall take all actions as may be reasonably necessary to consummate the sale
contemplated by this Section 4.03(f), including, without limitation, entering into agreements and delivering certificates
and instruments and consents as may be deemed necessary or appropriate. At the closing of any sale and purchase pursuant to this
Section 4.03(f), the Offering Stockholder shall deliver to the participating Applicable ROFR Rightholders certificates
(if any) representing the Offered Stock to be sold, free and clear of any liens or encumbrances (other than those contained in
this Agreement), accompanied by evidence of transfer and all necessary transfer taxes paid and stamps affixed, if necessary, against
receipt of the purchase price therefor from such Applicable ROFR Rightholders by certified or official bank check or by wire transfer
of immediately available funds.

 

    	 	 20	 

     

    

 

(g) Sale
to Proposed Purchaser. In the event that the Applicable ROFR Rightholders shall not have collectively elected to purchase
all of the Offered Stock, then, provided the Offering Stockholder has also complied with the provisions of Section 4.04 and
Section 4.01, to the extent applicable, the Offering Stockholder may Transfer all of such Offered Stock, at a price per
share for each applicable class or series of Offered Stock not less than that specified in the ROFR Notice and on other terms
and conditions which are not materially more favorable in the aggregate to the Prospective Transferee than those specified in
the ROFR Notice, but only to the extent that such Transfer occurs within ninety (90) days after expiration of the Applicable ROFR
Rightholder Option Period or, if applicable, the Exercising Applicable ROFR Rightholder Option Period. Any Offered Stock not Transferred
within such 90-day period will be subject to the provisions of this Section 4.03 upon subsequent Transfer.

 

(h) Termination.
This Section 4.03, and the covenants contained herein, shall terminate upon the earliest to occur of (i) the FTP Investors’
beneficial ownership of Common Stock is, in the aggregate, less than ten percent (10%) of the issued and outstanding Common Stock
(on a Fully Diluted Basis and, for the avoidance of doubt, including options that are not yet vested) or (ii) a Change of Control.

 

Section
4.04 Tag-along Right.

 

(a) Participation
on Sale of Stock. Subject to the terms and conditions specified in Section 4.01 and this Section 4.04, if any
Stockholder (the “Selling Stockholder”) proposes to Transfer all of its Shares (or Stock Equivalents) (collectively,
the “Tag-along Stock”) to any Person, each other Stockholder holding shares of Preferred Stock or Common Stock
(each, a “Tag-along Stockholder”) shall be permitted to participate in such sale (a “Tag-along Sale”)
on the terms and conditions set forth in this Section 4.04. This participation right and the terms and conditions set forth
in this Section 4.04 shall be applied separately on a class-by-class and series-by-series basis for each class or series
of Tag-along Stock, as applicable.

 

(b) Tag-along
Sale Exceptions. Notwithstanding anything herein to the contrary, the provisions of this Section 4.04 shall not
apply to any Transfer of Tag-along Stock that is:

 

(i)
permitted by and made in accordance with Section 4.02;

 

(ii)
made to any Applicable ROFR Rightholder pursuant to the exercise of the rights set forth in Section 4.03;
or

 

(iii) 
made pursuant to a Public Offering.

 

(c) Tag-along
Notice. The Selling Stockholder shall deliver to the Company and each other Tag-along Stockholder a written notice (a “Tag-along
Notice”) of the proposed Tag-along Sale within (i) five (5) Business Days following the expiration of the Applicable
ROFR Rightholder Option Period or, if applicable, the Exercising Applicable ROFR Rightholder Option Period, in the event that
the Applicable ROFR Rightholders shall not have, in the aggregate, exercised their respective rights to purchase all and not less
than all of the Offered Stock pursuant to Section 4.03, or (ii) twenty (20) Business Days prior to the consummation of
any Tag-along Sale which was not subject to Section 4.03.

 

    	 	 21	 

     

    

 

The
Tag-along Notice shall make reference to the Tag-along Stockholders’ rights hereunder and shall describe in reasonable detail:

 

(i) The
class(es) or series and applicable aggregate number of Tag-along Stock the Selling Stockholder proposes to Transfer;

 

(ii) The
identity of the prospective Transferee(s);

 

(iii)
The proposed date, time and location of the closing of the Tag-along Sale, which shall not be less than sixty (60) Business
Days from the date of the Tag-along Notice;

 

(iv) The
purchase price per share for each applicable class or series of Tag-along Stock (which shall be payable solely in cash) and the
other material terms and conditions of the Transfer; and

 

(v)  A
copy of any form of agreement proposed to be executed in connection therewith.

For
the avoidance of doubt, in the event of a Tag-along Sale involving more than one class or series of Tag-along Stock, the Selling
Stockholder may deliver a single Tag-along Notice to the Company and each Tag-along Stockholder.

 

(d)  Exercise
of Tag-along Right.

 

(i) Each
Tag-along Stockholder may exercise its right to participate in the Tag-along Sale on the terms described in the Tag-along Notice
by delivering to the Selling Stockholder a written notice (a “Tag-along Exercise Notice”) stating its election
to do so for each class or series of Tag-along Stock included in the Tag-along Notice no later than ten (10) Business Days after
receipt of the Tag-along Notice (the “Tag-along Exercise Period”). The election of each Tag-along Stockholder
set forth in a Tag-along Exercise Notice shall be irrevocable, and, to the extent the offer in the Tag-along Notice is accepted,
such Tag-along Stockholder shall be bound and obligated to consummate the Transfer on the terms and conditions set forth in this
Section 4.04. If one or more Tag-along Stockholders elects pursuant to a Tag-along Exercise Notice and this Section
4.04(d)(i) to participate in the Tag-along Sale, the number of each applicable class or series of Tag-along Stock that the
Selling Stockholder may sell in the Tag-along Sale shall be correspondingly reduced in accordance with Section 4.04(d)(ii).

 

(ii) The
Selling Stockholder and each Tag-along Stockholder timely electing to participate in the Tag-along Sale pursuant to Section
4.04(d)(i) shall have the right to Transfer in the Tag-along Sale the number of Shares (or applicable Stock Equivalents) of
each class or series of Tag-along Stock set out in the applicable Tag-along Notice, treated as separate classes for purposes of
this calculation, equal to the product of (A) the aggregate number of shares of the particular class or series of Tag-along Stock,
as the case may be, set out in the applicable Tag-along Notice and (B) such Stockholder’s Tag-along Pro Rata Portion for
the applicable class or series of Tag-along Stock. Any Tag-along Stockholder may elect to sell in the Tag-along Sale less than
the number of Shares (or Stock Equivalents) calculated pursuant to this Section 4.04(d)(ii) for any particular class or
series of Tag-along Stock, in which case the Selling Stockholder and each Tag-along Stockholder timely electing to sell its full
Tag-along Pro Rata Portion of each applicable class or series of Tag-along Stock in the Tag-along Sale pursuant to this Section
4.04(d)(ii) (each, a “Fully Electing Tag-along Stockholder”) shall have the right, pursuant to Section
4.04(e), to sell the applicable shares of Tag-along Stock not elected to be sold by a Tag-along Stockholder.

 

    	 	 22	 

     

    

 

(e) Remaining
Tag-along Stock.

 

(i)       If
any Tag-along Stockholder either declines to exercise its right to participate in any Tag-along Sale under Section 4.04(d)
or elects to exercise it with respect to less than its full Tag-along Pro Rata Portion for any class or series of Tag-along
Stock, the Selling Stockholder shall deliver a written notice (a “Remaining Tag-along Stock Notice”) to each
of the Fully Electing Tag-along Stockholders within five (5) Business Days following the expiration of the Tag-along Exercise
Period, informing each Fully Electing Tag-along Stockholder of the aggregate number of shares of each class or series of Tag-along
Stock that the Tag-along Stockholders have not elected to sell (such shares, the “Remaining Tag-along Stock”).
The Selling Stockholder and each Fully Electing Tag-along Stockholder shall be entitled to Transfer in the Tag-along Sale, in
addition to any applicable Shares (or Stock Equivalents) already being Transferred by such Stockholder pursuant to this Section
4.04, a number of Shares (or applicable Stock Equivalents) of each class or series of Remaining Tag-along Stock, treated separately
for purposes of this calculation, held by it equal to the product of (A) the number of Shares (or Stock Equivalents) of the applicable
class or series of Remaining Tag-along Stock, and (B) a fraction determined by dividing (1) the number of Shares (or applicable
Stock Equivalents) on a Fully Diluted Basis of the applicable class or series of Remaining Tag-along Stock owned by such Stockholder,
by (2) the aggregate number of Shares (or applicable Stock Equivalents) on a Fully Diluted Basis of the applicable class or series
of Remaining Tag-along Stock owned by the Selling Stockholder and all of the Fully Electing Tag-along Stockholders.

 

(ii)       Each
Fully Electing Tag-along Stockholder shall exercise its right to sell Remaining Tag-along Stock in accordance with Section
4.04(e)(i) by delivering to the Selling Stockholder a written notice (a “Remaining Tag-along Stock Exercise Notice”)
stating its election to do so and specifying the number of additional Shares (or applicable Stock Equivalents) of each applicable
class or series of Remaining Tag-along Stock held by it to be included in the Tag-along Sale pursuant to Section 4.04(e)(i)),
no later than five (5) Business Days after receipt of the Remaining Tag-along Stock Notice (the “Remaining Tag-along
Stock Exercise Period”).

 

(iii)       The
election of each Fully Electing Tag-along Stockholder set forth in a Remaining Tag-along Stock Exercise Notice shall be irrevocable,
and, to the extent the offer in the Tag-along Notice is accepted, such Fully Electing Tag-along Stockholder shall be bound and
obligated to consummate the Transfer of the additional Shares (or applicable Stock Equivalents) allocable to it on the terms and
conditions set forth in this Section 4.04.

 

    	 	 23	 

     

    

 

(f)       Waiver.
Each Tag-along Stockholder who does not deliver a Tag-along Exercise Notice in compliance with Section 4.04(d)(i) and each
Fully Electing Tag-along Stockholder who does not deliver a Remaining Tag-along Stock Exercise Notice in compliance with Section
4.04(e) shall be deemed to have waived all of such Tag-along Stockholder’s and all such Fully Electing Tag-along Stockholder’s
rights to participate in the Tag-along Sale with respect to the Capital Stock (or applicable Stock Equivalents) or, in the case
of a Fully Electing Tag-along Stockholder, the applicable portion thereof owned by such Tag-along Stockholder, and the Selling
Stockholder shall (subject to the rights of any other participating Tag-along Stockholder or Fully Electing Tag-along Stockholder)
thereafter be free to sell to the prospective Transferee the Tag-along Stock or Remaining Tag-along Stock, as applicable, identified
in the Tag-along Notice or the Remaining Tag-along Stock Exercise Notice, as applicable, at a per share price for each class or
series of such Tag-along Stock or Remaining Tag-along Stock, as applicable, that is no greater than the applicable per share price
set forth in the Tag-along Notice and on other terms and conditions which are not in the aggregate materially more favorable to
the Selling Stockholder than those set forth in the Tag-along Notice, without any further obligation to the non-accepting Tag-along
Stockholders or Fully Electing Tag-along Stockholders, as applicable.

 

(g)       Conditions
of Sale.

 

(i)       Each
Stockholder participating in the Tag-along Sale shall receive the same consideration per class or series of Tag-along Stock, after
deduction of such Stockholder’s proportionate share of the related expenses in accordance with Section 4.04(i) below.
In addition, no Transfer of any Tag-along Stock by the Selling Stockholder in the Tag-along Sale shall occur unless the prospective
Transferee simultaneously purchases the Shares (or applicable Stock Equivalents) elected to be sold by the Tag-along Stockholders
pursuant to Section 4.04(d)(i) and Section 4.04(e).

 

(ii)       Each
Tag-along Stockholder shall execute the applicable purchase agreement, if any, and shall make or provide the same representations,
warranties, covenants and indemnities as the Selling Stockholder makes or provides in connection with the Tag-along Sale; provided,
that each Tag-along Stockholder shall only be obligated to make representations and warranties that relate specifically to a Stockholder
(as opposed to the Company and its business) with respect to the Tag-along Stockholder’s title to and ownership of the applicable
Shares (or Stock Equivalents), authorization, execution and delivery of relevant documents, enforceability of such documents against
the Tag-along Stockholder, and other similar representations and warranties made by the Selling Stockholder, and shall not be
obligated to make any of the foregoing representations and warranties with respect to any other Stockholder or their Shares (or
Stock Equivalents); provided, further, that all indemnities and other obligations shall be made by the Selling Stockholder
and each Tag-along Stockholder severally and not jointly and severally (A) with respect to breaches of representations, warranties
and covenants made by the Selling Stockholder and the Tag-along Stockholders relating to the Company and its business, if any,
pro rata based on the aggregate consideration received by the Selling Stockholder and each Tag-along Stockholder in the Tag-along
Sale, and (B) in an amount not to exceed for the Selling Stockholder or any Tag-along Stockholder, the aggregate consideration
received by the Selling Stockholder and each such Tag-along Stockholder in connection with the Tag-along Sale, as applicable,
plus the amount of any consideration forfeited by the Selling Stockholder or such Tag-along Stockholder, as applicable,
to which it is entitled but has not yet received (including, without limitation, as a result of an escrow agreement, earn-out
or similar arrangement).

 

    	 	 24	 

     

    

 

(iii)       Each
holder of then currently exercisable Stock Equivalents with respect to a class or series of Tag-along Stock proposed to be Transferred
in a Tag-along Sale shall be given an opportunity to convert such Stock Equivalents into the applicable class or series of Tag-along
Stock prior to the consummation of the Tag-along Sale and participate in such sale as holders of such class or series of Tag-along
Stock.

 

(h)       Cooperation.
Subject to Section 4.04(g)(ii), each Tag-along Stockholder shall take all actions as may be reasonably necessary to consummate
the Tag-along Sale, including, without limitation entering into agreements and delivering certificates and instruments (including
stock certificates evidencing the applicable Shares, duly endorsed in blank or accompanied by stock powers or other instruments
of transfer duly executed in blank), in each case, consistent with the agreements being entered into and the certificates and
instruments being delivered by the Selling Stockholder.

 

(i)       Expenses.
The fees and expenses of the Selling Stockholder incurred in connection with a Tag-along Sale and for the benefit of all Tag-along
Stockholders (it being understood that costs incurred by or on behalf of a Selling Stockholder for its sole benefit will not be
considered to be for the benefit of all Tag-along Stockholders), to the extent not paid or reimbursed by the Company or the prospective
Transferee, shall be shared by the Selling Stockholder and all the participating Tag-along Stockholders on a pro rata basis, based
on the aggregate consideration received by each such Stockholder; provided, that no Tag-along Stockholder shall be obligated
to make any out-of-pocket expenditure prior to the consummation of the Tag-along Sale.

 

(j)       Consummation
of Sale. Subject to the requirements and conditions of this Section 4.04 and the other applicable provisions of this
Agreement, including Section 4.01 hereof, the Selling Stockholder shall have sixty (60) days following the expiration of
the Tag-along Exercise Period in which to consummate the Tag-along Sale, on terms not more favorable to the Selling Stockholder
than those set forth in the Tag-along Exercise Notice (which sixty (60) day period may be extended for a reasonable time not to
exceed ninety (90) days to the extent reasonably necessary to obtain required approvals or consents from any Governmental Authority).
If at the end of such period the Selling Stockholder has not completed the Tag-along Sale, the Selling Stockholder may not then
effect a Transfer that is subject to this Section 4.04 without again fully complying with the provisions of this Section
4.04. At the closing of the Tag-along Sale, each of the Tag-along Stockholders timely electing to participate in the Tag-along
Sale pursuant to Section 4.04(d)(i) shall enter into the agreements and deliver the certificates and instruments, in each
case, required by Section 4.04(g) and Section 4.04(h) against payment therefor directly to the Tag-along Stockholder
of the portion of the aggregate consideration to which each such Tag-along Stockholder is entitled in the Tag-along Sale in accordance
with the provisions of this Section 4.04.

 

(k)       Transfers
in Violation of the Tag-along Right. If the Selling Stockholder sells or otherwise Transfers to the prospective Transferee
any of its Capital Stock (or Stock Equivalents) in breach of this Section 4.04, then each Tag-along Stockholder shall have
the right to sell to the Selling Stockholder, and the Selling Stockholder undertakes to purchase from each Tag-along Stockholder,
the number of Shares (or applicable Stock Equivalents) of each applicable class or series that such Tag-along Stockholder would
have had the right to sell to the prospective Transferee pursuant to this Section 4.04, for a per share amount and form
of consideration and upon the terms and conditions on which the prospective Transferee bought such shares from the Selling Stockholder,
but without indemnity being granted by any Tag-along Stockholder to the Selling Stockholder; provided, that nothing contained
in this Section 4.04(k) shall preclude any Stockholder from seeking alternative remedies against such Selling Stockholder
as a result of its breach of this Section 4.04. The Selling Stockholder shall also reimburse each Tag-along Stockholder
for any and all reasonable and documented out-of-pocket fees and expenses, including reasonable legal fees and expenses, incurred
pursuant to the exercise or the attempted exercise of the Tag-along Stockholder’s rights under this Section 4.04(k).

 

    	 	 25

beneficial ownership of Common Stock is, in the aggregate, less than ten percent (10%) of the issued and outstanding Common Stock
(on a Fully Diluted Basis and, for the avoidance of doubt, including options that are not yet vested) or (ii) a Change of Control.

DEMAND REGISTRATION.

 

(a)
At any time after the date that is one-hundred and twenty (120) days after the date of this Agreement, holders of at least twenty
percent (20%) of the Registrable Securities then outstanding and held by Note Holders or their assignees pursuant to Section 15
(“Note Holder Parties”) may request registration under the Securities Act of all or any portion of their Registrable
Securities on Form S-1 or any successor form thereto (each a “Long-Form Registration”). Each request for a
Long-Form Registration shall specify the approximate number of Registrable Securities required to be registered. Upon receipt
of such request, the Issuer shall promptly (but in no event later than five (5) Business Days following receipt thereof) deliver
notice of such request to all other holders of Registrable Securities who shall then have five (5) Business Days from the date
such notice is given to notify the Issuer in writing of their desire to be included in such registration. Each holder of Registrable
Securities who is a Note Holder Party agrees that the fact that such a notice has been delivered shall constitute confidential
information. The Issuer shall cause a Registration Statement on Form S-1 (or any successor form) to be filed within seventy-five
(75) days after the date on which the initial request is given and shall use its reasonable best efforts to cause such Registration
Statement to be declared effective by the SEC as soon as practicable thereafter.

 

(b)
The Issuer shall use its reasonable best efforts to be and remain qualified to register securities under the Securities Act pursuant
to a Registration Statement on Form S-3 or any successor form thereto. At any time when the Issuer is qualified for the use of
a Registration Statement on Form S-3, the holders of Registrable Securities who are Note Holder Parties shall have the right to
request registrations of their Registrable Securities on Form S-3 or any similar short-form registration (each a “Short-Form
Registration” and, together with each Long-Form Registration, a “Demand Registration”). Each request
for a Short-Form Registration shall specify the approximate number of Registrable Securities requested to be registered. Upon
receipt of any such request, the Issuer shall promptly (but in no event later than five (5) Business Days following receipt thereof)
deliver notice of such request to all other holders of Registrable Securities who shall then have five (5) Business Days from
the date such notice is given to notify the Issuer in writing of their desire to be included in such registration. The Issuer
shall cause a Registration Statement on Form S-3 (or any successor form) to be filed within forty-five (45) days after the date
on which the initial request is given and shall use its reasonable best efforts to cause such Registration Statement to be declared
effective by the SEC as soon as practicable thereafter. The Issuer shall not be required to effect a Long-Form Registration or
a Short Form Registration more than five times in the aggregate for the holders of Registrable Securities held by the Note Holder
Parties as a group; provided, that a Registration Statement shall not count as a Long-Form Registration requested under
Section 2(a) or as a Short-Form Registration under this Section 2(b) unless and until it has become effective and the holders
requesting such registration are able to register and sell at least seventy-five percent (75%) of the Registrable Securities requested
to be included in such registration.

 

    	 	3	 

    	 		 

    

 

(c)
The Issuer shall not be obligated to effect any Demand Registration within a hundred and twenty (120) days after the effective
date of a previous Demand Registration or a previous Piggyback Registration in which holders of Registrable Securities were permitted
to register, and actually sold, all of the shares of Registrable Securities requested to be included therein. The Issuer may postpone
for up to twenty (20) Business Days the filing or effectiveness of a Registration Statement for a Demand Registration if the Issuer’s
Board of Directors determines in its reasonable good faith judgment that such Demand Registration would (i) materially interfere
with a significant acquisition, corporate organization or other similar transaction involving the Issuer; (ii) require premature
disclosure of material information that the Issuer has a bona fide business purpose for preserving as confidential; or (iii) render
the Issuer unable to comply with requirements under the Securities Act or Exchange Act; provided, that in such event the
holders of a majority of the Registrable Securities initiating such Demand Registration shall be entitled to withdraw such request
and, if such request is withdrawn, such Demand Registration shall not count as one of the permitted Demand Registrations hereunder
and the Issuer shall pay all registration expenses in connection with such registration. The Issuer may delay a Demand Registration
hereunder only twice in any period of twelve (12) consecutive months.

 

(d)
If the holders of the Registrable Securities initially requesting a Demand Registration elect to distribute the Registrable Securities
covered by their request in an underwritten offering, they shall so advise the Issuer as a part of their request made pursuant
to Section 2(a) or Section 2(b), and the Issuer shall include such information in its notice to the other holders of Registrable
Securities. The holders of a majority of the Registrable Securities initially requesting the Demand Registration shall select
the investment banking firm or firms to act as the managing underwriter or underwriters in connection with such offering; provided,
that such selection shall be subject to the consent of the Issuer, which consent shall not be unreasonably withheld or delayed.

 

(e)
The Issuer shall not include in any Demand Registration any securities which are not Registrable Securities without the prior
written consent of the holders of a majority of the Registrable Securities included in such registration, which consent shall
not be unreasonably withheld or delayed. If a Demand Registration involves an underwritten offering and the managing underwriter
of the requested Demand Registration advises the Issuer and the holders of Registrable Securities in writing that in its opinion
the number of shares of Common Stock proposed to be included in the Demand Registration, including all Registrable Securities
and all other shares of Common Stock proposed to be included in such underwritten offering, exceeds the number of shares of Common
Stock which can be sold in such underwritten offering and/or the number of shares of Common Stock proposed to be included in such
registration would adversely affect the price per share of the Registrable Securities proposed to be sold in such underwritten
offering, the Issuer shall include in such Demand Registration (i) first, the number of shares of Common Stock that the holders
of Registrable Securities who are Note Holder Parties propose to sell, (ii) second, the number of shares of Common Stock that
the other holders of Registrable Securities propose to sell and (iii) third, the number of shares of Common Stock proposed to
be included therein by any other Persons (including shares of Common Stock to be sold for the account of the Issuer and/or other
holders of Common Stock) allocated among such Persons in such manner as they may agree. If the managing underwriter determines
that less than all of the Registrable Securities proposed to be sold can be included in such offering, then the Registrable Securities
that are included in such offering shall be allocated pro rata among the respective holders thereof on the basis of the number
of Registrable Securities owned by each such holder.

3.
PIGGYBACK REGISTRATION

 

(a)
Whenever the Issuer proposes to register any shares of its Common Stock under the Securities Act (other than a registration effected
solely to implement an employee benefit plan or a transaction to which Rule 145 of the Securities Act is applicable, or a Registration
Statement on Form S-4, S-8 or any successor form thereto or another form not available for registering the Registrable Securities
for sale to the public), whether for its own account or for the account of one or more stockholders of the Issuer and the form
of Registration Statement to be used may be used for any registration of Registrable Securities (a “Piggyback Registration”),
the Issuer shall give prompt written notice (in any event no later than ten (10) Business Days prior to the filing of such Registration
Statement) to the holders of Registrable Securities of its intention to effect such a registration and, subject to Section 3(b)
and Section 3(c), shall include in such registration all Registrable Securities with respect to which the Issuer has received
written requests for inclusion from the holders of Registrable Securities within five (5) Business Days after the Issuer’s
notice has been given to each such holder. Each holder of Registrable Securities agrees that the fact that such a notice has been
delivered shall constitute confidential information. A Piggyback Registration shall not be considered a Demand Registration for
purposes of Section 2 of this Agreement.

 

(b)
If a Piggyback Registration is initiated as a primary underwritten offering on behalf of the Issuer and the managing underwriter
advises the Issuer and the holders of Registrable Securities (if any holders of Registrable Securities have elected to include
Registrable Securities in such Piggyback Registration) in writing that in its opinion the number of shares of Common Stock proposed
to be included in such registration, including all Registrable Securities and all other shares of Common Stock proposed to be
included in such underwritten offering, exceeds the number of shares of Common Stock which can be sold in such offering and/or
that the number of shares of Common Stock proposed to be included in any such registration would adversely affect the price per
share of the Common Stock to be sold in such offering, the Issuer shall include in such registration (i) first, the number of
shares of Common Stock that the Issuer proposes to sell; (ii) second, the number of shares of Common Stock requested to be included
therein by holders of Registrable Securities, allocated pro rata among all such holders on the basis of the number of Registrable
Securities owned by each such holder or in such manner as they may otherwise agree; and (iii) third, the number of shares of Common
Stock requested to be included therein by holders of Common Stock (other than holders of Registrable Securities), allocated among
such holders in such manner as they may agree; provided, that in any event the holders of Registrable Securities shall
be entitled to register at least twenty-five percent (25%) of the securities to be included in any such registration.

 

    	 	5	 

    	 		 

    

 

(c)
If a Piggyback Registration is initiated as an underwritten offering on behalf of a holder of Common Stock other than Registrable
Securities, and the managing underwriter advises the Issuer in writing that in its opinion the number of shares of Common Stock
proposed to be included in such registration, including all Registrable Securities and all other shares of Common Stock proposed
to be included in such underwritten offering, exceeds the number of shares of Common Stock which can be sold in such offering
and/or that the number of shares of Common Stock proposed to be included in any such registration would adversely affect the price
per share of the Common Stock to be sold in such offering, the Issuer shall include in such registration (i) first, the number
of shares of Common Stock requested to be included therein by the holder(s) requesting such registration and by the holders of
Registrable Securities, allocated pro rata among such holders on the basis of the number of shares of Common Stock (on a fully
diluted, as converted basis) and the number of Registrable Securities, as applicable, owned by all such holders or in such manner
as they may otherwise agree; and (ii) second, the number of shares of Common Stock requested to be included therein by other holders
of Common Stock, allocated among such holders in such manner as they may agree.

 

(d)
If any Piggyback Registration is initiated as a primary underwritten offering on behalf of the Issuer, the Issuer shall select
the investment banking firm or firms to act as the managing underwriter or underwriters in connection with such offering.

 

4.

marketing activities (including one-on-one meetings with prospective purchasers of the Registrable Securities);

 

    	 	7

its stockholders an earnings statement (in a form that satisfies the provisions of Rule 158 under the Securities Act) no later
than thirty (30) days after the end of the 12-month period beginning with the first day of the Issuer’s first full fiscal
quarter after the effective date of such Registration Statement, which earnings statement shall cover said 12-month period, and

5.
GRACE PERIODS AND LIQUIDATED DAMAGES.

 

(a)
Notwithstanding anything to the contrary herein, at any time after the effective date of a Registration Statement, the Issuer
may delay the disclosure of material, non-public information if the Issuer’s Board of Directors determines in its reasonable
good faith judgment that such disclosure would (i) materially interfere with a significant acquisition, corporate organization
or other similar transaction involving the Issuer; (ii) require premature disclosure of material information that the Issuer has
a bona fide business purpose for preserving as confidential; or (iii) render the Issuer unable to comply with requirements under
the Securities Act or Exchange Act (a “Grace Period”); provided, that the Company shall promptly (1) notify
the Investors in writing in accordance with Section 4(g) of such Grace Period and the date on which the Grace Period will begin,
and (2) notify the Investors in writing of the date on which the Grace Period ends; and, provided further, that no Grace Period
shall exceed twenty (20) consecutive Business Days and during any twelve month period such Grace Periods shall not exceed an aggregate
of forty (40) Business Days and the first day of any Grace Period must be at least five (5) Business Days after the last day of
any prior Grace Period (each, an “Allowable Grace Period”). For purposes of determining the length of a Grace
Period above, the Grace Period shall begin on and include the date the Investors receive the notice referred to in clause (1)
and shall end on and include the later of the date the Investors receive the notice referred to in clause (2) and the date referred
to in such notice. The amendment and prospectus supplement provisions of Section 4(g) shall not be applicable during the period
of any Allowable Grace Period.

 

(b)
If on any day after the effective date of a Registration Statement, sales of all of the Registrable Securities included on such
Registration Statement cannot be made (other than during an Allowable Grace Period) pursuant to such Registration Statement or
otherwise (including, without limitation, because of the suspension of trading of the Common Stock on the securities exchange
or the over-the-counter market on which such Common Stock is then traded, a failure to keep such Registration Statement effective,
a failure to disclose such information as is necessary for sales to be made pursuant to such Registration Statement or the Registration
Statement ceases to be effective for any reason or the prospectus contained therein is not available for use for any reason),
or the Issuer fails to file with the SEC any required reports under Section 13 or 15(d) of the Exchange Act such that it is not
in compliance with Rule 144(c)(1) (or Rule 144(i)(2), if applicable) as a result of which any of the Investors are unable to sell
Registrable Securities without restriction under Rule 144 (including, without limitation, volume restrictions) then, as partial
relief for the damages to any holder by reason of any such delay in or reduction of its ability to sell the underlying shares
of Common Stock (which remedy shall not be exclusive of any other remedies available at law or in equity, including, without limitation,
specific performance or any additional obligation of to register Registrable Securities pursuant to this Agreement) (any such
event, a “Failure”), the Issuer shall pay to each holder of Registrable Securities relating to such Registration
Statement, a cash amount equal to, or, at such holder’s election if offered by the Company, warrants to purchase Common
Stock of the Issuer with a Black-Scholes value of no less than, one percent (1%) of the market value (based upon the most recent
closing price of the Common Stock on the securities exchange or over-the-counter market on which such Common Stock has been traded)
of such Investor’s Registrable Securities, on the thirtieth day after the date of a Failure and every thirtieth day thereafter
(pro-rated for periods totaling less than thirty (30) days) until such Failure is cured. Notwithstanding anything to the contrary
contained herein, (i) such payments shall cease to accrue when all of the Registrable Securities may be sold pursuant to Rule
144 without any restrictions or limitations, and (ii) in no event shall the aggregate amount of all such payments paid to an Investor
exceed an amount equal to ten percent (10%) of such Investor’s original purchase price for the Registrable Securities.

by any such registration, fees and expenses of complying with securities and “blue sky” Laws, printing expenses, fees

7.
INDEMNIFICATION

 

In
the event any Registrable Securities are included in a Registration Statement under this Agreement:

 

(a)
To the fullest extent permitted by law, the Issuer will, and hereby does, indemnify, hold harmless and defend each Note Holder
or other holder of Registrable Securities or transferee thereof in accordance with Section 15 (the “Investor”),
the directors, officers, partners, members, employees, agents, representatives of, and each Person, if any, who controls any Investor
within the meaning of the Securities Act or the Exchange Act (each, an “Indemnified Person”), against any losses,
claims, damages, liabilities, judgments, fines, penalties, charges, costs, reasonable attorneys’ fees, amounts paid in settlement
or expenses, joint or several (collectively, “Claims”), incurred in investigating, preparing or defending any
action, claim, suit, inquiry, proceeding, investigation or appeal taken from the foregoing by or before any court or governmental,
administrative or other regulatory agency, body or the SEC, whether pending or threatened, whether or not an indemnified party
is or may be a party thereto (“Indemnified Damages”), to which any of them may become subject insofar as such
Claims (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon:

 

    	 	10	 

    	 		 

    

 

(i)
any untrue statement or alleged untrue statement of a material fact in a Registration Statement or any post-effective amendment
thereto or in any filing made in connection with the qualification of the offering under the securities or other “blue sky”
laws of any jurisdiction in which Registrable Securities are offered (“Blue Sky Filing”), or the omission or
alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading;

 

(ii)
any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus if used prior to the
effective date of such Registration Statement, or contained in the final prospectus (as amended or supplemented, if the Issuer
files any amendment thereof or supplement thereto with the SEC) or the omission or alleged omission to state therein any material
fact necessary to make the statements made therein, in light of the circumstances under which the statements therein were made,
not misleading;

 

(iii)
any violation or alleged violation by the Issuer of the Securities Act, the Exchange Act, any other law, including, without limitation,
any state securities law, or any rule or regulation thereunder relating to the offer or sale of the Registrable Securities pursuant
to a Registration Statement; or

 

(iv)
any violation of this Agreement (the matters in the foregoing clauses (i) through (iv) being, collectively, “Violations”).

 

Subject
to Section 7(c), the Issuer shall reimburse the Indemnified Persons, promptly as such expenses are incurred and are due and payable,
for any reasonable legal fees or other expenses incurred by them in connection with investigating or defending any such Claim.
Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 7(a): (1) shall
not apply to a Claim by an Indemnified Person arising out of or based upon a Violation which occurs in reliance upon and in conformity
with information furnished in writing to the Issuer by such Indemnified Person for such Indemnified Person expressly for use in
connection with the preparation of the Registration Statement or any such amendment thereof or supplement thereto, if such prospectus
was timely made available by the Issuer; and (2) shall not apply to amounts paid in settlement of any Claim if such settlement
is effected without the prior written consent of the Issuer, which consent shall not be unreasonably withheld or delayed. Such
indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Person
and shall survive the transfer of any of the Registrable Securities by an Investor pursuant to Section 15.

 

    	 	11	 

    	 		 

    

 

(b)
In connection with any Registration Statement in which an Investor is participating, each such Investor agrees to severally and
not jointly indemnify, hold harmless and defend, to the same extent and in the same manner as is set forth in Section 7(a), the
Issuer, each of its directors, each of its officers who signs the Registration Statement and each Person, if any, who controls
the Issuer within the meaning of the Securities Act or the Exchange Act (each, an “Indemnified Party”), against
any Claim or Indemnified Damages to which any of them may become subject, under the Securities Act, the Exchange Act or otherwise,
insofar as such Claim or Indemnified Damages arise out of or are based upon any Violation, in each case to the extent, and only
to the extent, that such Violation occurs in reliance upon and in conformity with written information furnished to the Issuer
by such Investor expressly for use in connection with such Registration Statement; and, subject to Section 7(c), such Investor
shall reimburse the Indemnified Party for any legal or other expenses reasonably incurred by an Indemnified Party in connection
with investigating or defending any such Claim; provided, however, that the indemnity agreement contained in this Section 7(b)
and the agreement with respect to contribution contained in Section 7(f) shall not apply to amounts paid in settlement of any
Claim if such settlement is effected without the prior written consent of such Investor, which consent shall not be unreasonably
withheld or delayed; provided, further, however, that the Investor shall be liable under this Section 7(b) for only that amount
of a Claim or Indemnified Damages as does not exceed the net proceeds to such Investor as a result of the sale of Registrable
Securities pursuant to such Registration Statement. Such indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of such Indemnified Party and shall survive the transfer of the Registrable Securities by an Investor pursuant
to Section 15.

 

(c)
Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 7 of notice of the commencement of any
action or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person or Indemnified
Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section 7, deliver to the indemnifying
party a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to
the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of
the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified
Party, as the case may be; provided, however, that an Indemnified Person or Indemnified Party shall have the right to retain its
own counsel with the fees and expenses of not more than one counsel for all such Indemnified Person or Indemnified Party to be
paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the Indemnified Person or Indemnified Party,
as applicable, the representation by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would
be inappropriate due to actual or potential differing interests between such Indemnified Person or Indemnified Party and any other
party represented by such counsel in such proceeding. In the case of an Indemnified Person, legal counsel referred to in the immediately
preceding sentence shall be selected by the Investors holding at least a majority in interest of the Registrable Securities included
in the Registration Statement to which the Claim relates. The Indemnified Party or Indemnified Person shall reasonably cooperate
with the indemnifying party in connection with any negotiation or defense of any such action or Claim by the indemnifying party
and shall furnish to the indemnifying party all information reasonably available to the Indemnified Party or Indemnified Person
which relates to such action or Claim. The indemnifying party shall keep the Indemnified Party or Indemnified Person fully apprised
at all times as to the status of the defense or any settlement negotiations with respect thereto. No indemnifying party shall
be liable for any settlement of any action, claim or proceeding effected without its prior written consent, provided, however,
that the indemnifying party shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall, without
the prior written consent of the Indemnified Party or Indemnified Person, consent to entry of any judgment or enter into any settlement
or other compromise which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified
Party or Indemnified Person of a release from all liability in respect to such Claim or litigation and such settlement shall not
include any admission as to fault on the part of the Indemnified Party. Following indemnification as provided for hereunder, the
indemnifying party shall be subrogated to all rights of the Indemnified Party or Indemnified Person with respect to all third
parties, firms or corporations relating to the matter for which indemnification has been made. The failure to deliver written
notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying
party of any liability to the Indemnified Person or Indemnified Party under this Section 7, except to the extent that the indemnifying
party is prejudiced in its ability to defend such action.

 

    	 	12	 

    	 		 

    

 

(d)
The indemnification required by this Section 7 shall be made by periodic payments of the amount thereof during the course of the
investigation or defense, as and when bills are received or Indemnified Damages are incurred.

 

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

 

(f)
To the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make
the maximum contribution with respect to any amounts for which it would otherwise be liable under this Section 7 to the fullest
extent permitted by law; provided, however, that: (i) no Person involved in the sale of Registrable Securities which Person is
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) in connection with such sale
shall be entitled to contribution from any Person involved in such sale of Registrable Securities who was not guilty of fraudulent
misrepresentation; and (ii) contribution by any seller of Registrable Securities shall be limited in amount to the amount of net
proceeds received by such seller from the sale of such Registrable Securities pursuant to such Registration Statement. Notwithstanding
the provisions of this Section 7(f), no Investor shall be required to contribute, in the aggregate, any amount in excess of the
amount by which the net proceeds actually received by such Investor from the applicable sale of the Registrable Securities subject
to the Claim exceeds the amount of any damages that such Investor has otherwise been required to pay, or would otherwise be required
to pay under Section 7(b), by reason of such untrue or alleged untrue statement or omission or alleged omission.

 

8.
PARTICIPATION IN UNDERWRITTEN REGISTRATIONS

 

No
Person may participate in any registration hereunder which is underwritten unless such Person, (a) agrees to sell such Person’s
securities on the basis provided in any underwriting arrangements approved by the Person or Persons entitled hereunder to approve
such arrangements and (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements
and other documents required under the terms of such underwriting arrangements; provided, that no holder of Registrable
Securities included in any underwritten registration shall be required to make any representations or warranties to the Issuer
or the underwriters (other than representations and warranties regarding such holder, such holder’s ownership of its shares
of Common Stock to be sold in the offering and such holder’s intended method of distribution) or to undertake any indemnification
obligations to the Issuer or the underwriters with respect thereto, except as otherwise provided in Section 7.

 

    	 	13	 

    	 		 

    

 

9.
RULE 144 COMPLIANCE

 

With
a view to making available to the holders of Registrable Securities the benefits of Rule 144 and any other rule or regulation
of the SEC that may at any time permit a holder to sell securities of the Issuer to the public without registration or pursuant
to a registration on Form S-3 (or any successor form), the Issuer shall:

 

(a)
make and keep public information available, as those terms are understood and defined in Rule 144, at all times after the Registration
Date;

 

(b)
use reasonable best efforts to file with the SEC in a timely manner all reports and other documents required of the Issuer under

(c)
furnish to any holder so long as the holder owns Registrable Securities, promptly upon request, a written statement by the Issuer
as to its compliance with the reporting requirements of Rule 144 and of the Securities Act and the Exchange Act, a copy of the

10.
PRESERVATION OF RIGHTS

 

The
Issuer shall not (a) grant any registration rights to third parties which are more favorable than or inconsistent with the rights

TERMINATION

 

This
Agreement shall terminate and be of no further force or effect when there shall no longer be any Registrable Securities outstanding;

REMEDIES

 

Each
holder of Registrable Securities, in addition to being entitled to exercise all rights granted by Law, including recovery of damages,
shall be entitled to specific performance of its rights under this Agreement. The Issuer acknowledges that monetary damages would
not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Agreement and the Issuer
hereby agrees to waive the defense in any action for specific performance that a remedy at Law would be adequate.

as otherwise provided herein, the provisions of this Agreement may only be amended, modified, supplemented or waived with the

by any Party shall operate or be construed as a waiver in respect of any failure, breach or default not expressly identified by
such written waiver, whether of a similar or different character, and whether occurring before or after that waiver. Except as
otherwise set forth in this Agreement, no failure to exercise, or delay in exercising, any right, remedy, power or privilege arising
from this Agreement shall operate or be construed as a waiver thereof; nor shall any single or partial exercise of any right,
remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy,
power or privilege.
