Article

Management

 

Section
2.01 Board Composition. To the fullest extent permitted by Applicable Law, each Stockholder shall vote all voting securities
(including all voting Shares) owned by such Stockholder or over which such Stockholder has voting control, and shall take all
other reasonably necessary or desirable actions within his, her or its control (including in his, her or its capacity as a stockholder,
director, member of a board committee, officer of the Company or otherwise), and the Company shall take all reasonably necessary
or desirable actions within its control, to ensure that: 

 

(i)
so long as the Investors beneficially own, in the aggregate, not less than five percent (5%) of the issued and outstanding Common
Stock (calculated on a Fully Diluted Basis and, for the avoidance of doubt, including options that are not yet vested), the Investors
will be entitled to nominate such integral number of members of the Board of Directors of the Company (each member a “Director”
and, collectively, the “Board” ) as is proportionate (or as close to proportionate as practicable in light
of the number of Directors that constitute the Board) to its percentage of beneficial ownership of the outstanding Common Stock
(calculated on a Fully Diluted Basis), but in any event at least one (the “Investor Nominees”, and upon election
to the Board, the “Investor Directors”);

 

(ii)
on and as of the date of the Closing under (and as defined in) the Option Agreement, the Board shall consist of not less than
eight (8) Directors, with not less than three (3) of such Directors being Investor Directors (notwithstanding the provisions of
Section 2.04(ix), if complying with this Section 2.01(ii) requires increasing the number of Directors to eight (8)
Directors, such increase shall not require an affirmative vote of a Supermajority of the Board); and 

 

(iii)
within one year of the date of this Agreement, the Investors and the Management Stockholders shall mutually agree on a slate of
either five or six directors for the Board, including independent directors, to be nominated for election at a meeting of shareholders
of the Company, which slate shall include such number of Investor Nominees as is proportionate (or as close to proportionate as
practicable in light of the number of Directors that constitute the Board) to the Investors’ percentage of beneficial ownership
of the outstanding Common Stock (calculated on a Fully Diluted Basis), and the Company shall take such corporate actions as shall
be reasonably necessary to reduce the size of the Board to consist of such number of Board seats as shall be mutually agreed by

Section
2.02 Removal; Resignation; Vacancies.

 

(a)
Removal. An Investor Director may be removed at any time as a Director on the Board (with or without cause) upon, and only
upon, the written request of the Investors, except as required by Applicable Law. Each other Stockholder shall vote all voting
securities (including all voting Shares) owned by such Stockholder or over which such Stockholder has voting control, and shall
take all other necessary or desirable actions within his, her or its control (including in his, her or its capacity as a stockholder,
director, member of a board committee, officer of the Company or otherwise), and the Company shall take all necessary or desirable
actions within its control, to remove or replace from the Board such Investor Director upon, and only upon, such written request.
Except as provided in the preceding sentence, unless the Investors shall otherwise consent in writing, to the fullest extent permitted
by Applicable Law, no other Stockholder shall take any action to cause the removal of an Investor Director. 

 

(b)
Resignation. A Director may resign at any time from the Board by delivering his written resignation to the Board. Any such
resignation shall be effective upon receipt thereof unless it is specified to be effective at some other time or upon the occurrence
of some other event. The Board’s acceptance of a resignation shall not be necessary to make it effective.

 

(c)
Vacancies. In the event that a vacancy is created on the Board at any time due to the death, disability, retirement, resignation
or removal of an Investor Director, then the Investors shall have the right to designate an individual to fill such vacancy and
the Company and each Stockholder (whether in his, her 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 Investors shall fail to designate
in writing a representative to fill a vacant Investor Director position on the Board, and such failure shall continue for more
than thirty (30) days after notice from the Company to the Investors with respect to such failure, then the vacant position shall
be filled by an individual designated by the Investor Directors then in office; provided, that such individual shall be
removed from such position if the Investors so direct and simultaneously designate a new Investor Director.

 

Section
2.03 Meetings of the Board of Directors.

 

(a)
Generally. The Board shall meet at such time and at such place as the Board may designate. Meetings of the Board may be
held either in person or by means of telephone or video conference or other communications device that permits all Directors participating
in the meeting to hear each other, at the offices of the Company or such other place (either within or outside the State of Nevada)
as may be determined from time to time by the Board. Written notice of each meeting of the Board shall be given to each Director
at least 48 hours prior to each such meeting.

 

    	10

    	 

    

 

(b)
Special Meetings. Special meetings of the Board shall be held on the call of such number of directors and upon such notice
as provided in the Company’s bylaws. Any Director may waive such notice as to himself or herself.

 

(c) 
Quorum Requirements. The presence of a majority of Directors then in office shall constitute a quorum. If a quorum is not
achieved at any duly called meeting, such meeting may be postponed to a time no earlier than 24 hours after written notice of
such postponement has been given to the Directors. 

 

(d)
Recusal. Each Investor Director may recuse himself or herself from being present or participating at a meeting at which
a matter is considered in which the Investors’ interest as the Note Holders under the Notes Agreement can be reasonably
expected to be in conflict with the Investors’ interest as Stockholders, or voting on any such matter, and the Board may
require each Investor Director to recuse himself or herself from being present or participating at such a meeting or voting on
such a matter. Any recused Investor Director may be counted in determining the presence of a quorum at any meeting at which such
a matter is considered but his or her vote shall not be counted in determining the number of required votes to approve such matter
if he either voluntarily or mandatorily recuses himself or herself.

 

Section
2.04        Special Approval Matters. Until such time that the Investors beneficially own,
in the aggregate, less than five percent (5%) 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, but excluding any such beneficial ownership attributable to the
holding of Notes under the Notes Agreement), the following actions shall require the affirmative vote of a Supermajority of the
Board:

 

(i)

or (ii) a Change of Control.

 

Article
III

Pre-emptive
Rights

 

Section
3.01 Pre-emptive Right.

 

(a) 
Issuance of New Securities. So long as the Investors beneficially own, in the aggregate, not less than fifteen percent
(15%) of the issued and outstanding Common Stock, the Company hereby grants to the Investors (in such a case, the “Pre-emptive
Stockholder”) a right to purchase up to forty percent (40%) of any New Securities that the Company may from time to
time propose to issue or sell to any Person; provided, that the provisions of this Section 3.01 shall not apply
to any Excluded Issuance.

 

(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:

 

    	13

    	 

    

 

(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.

 

(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 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
Stockholder 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 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 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 Investors’ beneficial ownership of Common Stock is, in the aggregate, less than fifteen percent (15%) 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.

Offered Stock. At any time prior to the termination contemplated in Section 3.01(g), and subject to the terms and
conditions specified in Section 4.01, Section 4.02, this Section 4.03 and Section 4.04, the Investors
and each Management Stockholder holding Preferred Stock or Common Stock (collectively with the Investor, the “ROFR Rightholders”)
shall have a right of first refusal if any other Management Stockholder (the “Offering Stockholder”) receives
a bona fide offer from any Person (a “Prospective Transferee”) that the Offering Stockholder desires to accept
(a “Transfer Offer”) to Transfer all or any portion of any Shares (or applicable Stock Equivalents) it owns

other than the Offering Stockholder (the “Applicable ROFR Rightholders”), all in accordance with the following

separately on a class-by-class and series-by-series basis for each class or series of Offered Stock, as applicable (including
for purposes of calculating the respective ROFR pro rata portions in Section 4.03(d)). 

 

    	17

    	 

    

 

(b)

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

 

(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; or

 

(iii) 
made pursuant to a Public Offering.

 

(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;

 

	(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

 

    	18

    	 

    

 

	(D)		the
                                         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 until the end
of the Applicable ROFR Rightholder Option Period described in Section 4.03(d)(ii).

 

(iii) 
By delivering the ROFR Notice, the Offering Stockholder represents and warrants to the Company and each Applicable ROFR Rightholder
that:

 

	(A)		the
                                         Offering Stockholder has full right, title and interest in and to the Offered Stock described
                                         in the ROFR Notice;

 

	(B)		the
                                         Offering Stockholder has all the necessary power and authority and has taken all necessary
                                         action to Transfer the Offered Stock described in the ROFR Notice as contemplated by
                                         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.

 

(d)
Exercise of Right of First Refusal; Over-Allotment Option.

 

(i)  
Upon receipt of the ROFR Notice, each Applicable ROFR Rightholder shall have the right to purchase the Offered Stock on the terms
and purchase price(s) set forth in the ROFR Notice. The Applicable ROFR Rightholders shall have the right to purchase all (but
not less than all) of their respective ROFR Pro Rata Portions of each class or series of the remaining Offered Stock, in accordance
with the procedures set forth in Section 4.03(d)(ii). Notwithstanding the foregoing, the Applicable ROFR Rightholders may
only exercise their right to purchase the Offered Stock if, after giving effect to all 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.

 

(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.

 

    	19

    	 

    

 

(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 Rightholders (an “Exercising Applicable
ROFR Rightholder Notice”) stating the number(s) and type(s) of remaining Offered Stock available for purchase following
the Applicable ROFR Rightholder Exercise Period. For a period of ten (10) Business Days following the receipt of an Exercising
Applicable ROFR Rightholder Notice (such period, the “Exercising Applicable ROFR Rightholder Option Period”),
each Exercising Applicable ROFR Rightholder shall have the right to elect to purchase all or any portion of each class or series
of remaining Offered Stock by delivering a written notice to the Company and the Offering Stockholder (an “Exercising
Applicable ROFR Rightholder Exercise Notice”) specifying the number(s) and type(s) of additional remaining Offered Stock
it desires to purchase on the terms and applicable purchase price(s) set forth in the ROFR Notice. The Exercising Applicable ROFR
Rightholder Exercise Notice shall be binding upon delivery and irrevocable by the Exercising Applicable ROFR Rightholder.

 

(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 of the Exercising Applicable ROFR Rightholder Option Period, each class or series of remaining Offered Stock shall
be allocated for purchase among the Exercising Applicable ROFR Rightholders, as follows:

 

(i)  
First, to each Exercising Applicable ROFR Rightholder having elected pursuant to Section 4.03(d)(ii) to purchase its entire
ROFR Pro Rata Portion of each class or series of remaining Offered Stock, such Applicable ROFR Rightholder’s ROFR Pro Rata
Portion of each class or series of such remaining Offered Stock; and

 

(ii)
Second, 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:

 

    	20

    	 

    

 

	(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.

(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 Investors’ beneficial ownership of Common Stock is, in the aggregate, less than fifteen percent (15%) of the issued

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 any 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.

 

    	22

    	 

    

 

(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. 

 

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).

 

    	23

    	 

    

 

(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.

 

(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.

 

    	24

    	 

    

 

(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.

 

(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).

 

    	25

    	 

    

 

(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.

 

    	26

    	 

    

 

(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).

 

(l)
Termination. This Section 4.04, and the covenants contained herein, shall terminate upon the earliest to occur of
(i) the Investors’ beneficial ownership of Common Stock is, in the aggregate, less than fifteen percent (15%) 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.

The Issuer shall not be permitted to prepay all or any portion of the Notes except as expressly permitted under this Section 3.3,
unless each of the Note Holders otherwise consent in writing. For the avoidance of doubt, any amount prepaid on the Notes may
not be reborrowed and the Commitment shall be permanently reduced by the amount of such prepayment.

 

(ii)
After the occurrence of the first anniversary of the Closing Date, subject to Sections 3.3A(iii) and 3.3A(iv), if the Note Holders
have made to the Issuer Advances in an aggregate principal amount of not less than $18,000,000, the Issuer shall be permitted
to prepay in full the aggregate principal amount outstanding under the Notes. The Issuer shall make such prepayment in four equal
installments in the aggregate equal to the Total Prepayment Amount (as defined below), with one installment payable on each of
four consecutive Quarterly Dates, and shall make such prepayment together with all accrued and unpaid interest on the applicable
amount of principal to be prepaid to the applicable Quarterly Date, calculated in accordance with Section 3.2, payable on such
Quarterly Date on which prepayment is made. The Issuer shall provide a Prepayment Notice of not less than thirty (30) days and
not more than sixty (60) days prior to the Quarterly Date on which the first prepayment installment is to be made. Any Prepayment
Notice shall, as a condition of making such prepayment, be accompanied by written evidence satisfactory to the Note Holders that
the Issuer has arranged alternative debt or equity financing for the Total Prepayment Amount on commercially reasonable terms
with pricing, maturity and other material terms that are more favorable to the Issuer than the terms provided under this Agreement
and the Notes (“Prepayment Refinancing Evidence”).

 

(iii)
If the Issuer desires to make a prepayment in accordance with the provisions of Section 3.3A(ii), the Issuer shall pay the following
amounts, (the sum of the following amounts, the “Total Prepayment Amount”):

Date, the Make Whole Premium. 

 

(iv)
Notwithstanding receipt of the Prepayment Notice or the Prepayment Refinancing Evidence, the Note Holders have the right,
prior to any date of prepayment contemplated by Section 3.3A, to convert to Common Stock, pursuant to the terms of the Notes,
all or any portion of the principal then outstanding on the Notes, together with all accrued and unpaid interest thereon and,
if applicable, all premium thereon.

 

(v)
Following the delivery of any Prepayment Notice for a prepayment contemplated by Section 3.3A, the Issuer shall not be entitled
to any further Advances under this Agreement. Any Prepayment Notice shall be irrevocable and the Total Prepayment Amount shall
be due and payable on the Quarterly Dates as provided in this Section 3.3A.

 

B.
Mandatory Prepayments. Unless the Note Holders otherwise consent or waive in writing, the Issuer shall prepay the Notes in
the circumstances and amounts as specified as follows: in the event that (a) on or after the first anniversary of the Closing
Date, the Issuer issues any Equity Interests, and (b) the Note Holders shall not have exercised their right of first refusal to
purchase such Equity Interests pursuant to Section 4.03 of the Stockholder Rights Agreement, promptly after such issuance, the
Issuer shall prepay the Notes in a principal amount equal to twenty-five per cent (25%) of the Net Proceeds of such issuance plus
accrued interest on such principal amount plus, in the case of any such issuance on or prior to the second anniversary of the
Closing Date, the Make Whole Premium, which shall be payable in four equal installments on the date of such prepayment and the
next three succeeding Quarterly Dates to occur. The Note Holders may waive the obligation on the Issuer to make any prepayment
pursuant to this Section 3.3B with respect to any issuance of Equity Interests only if such waiver is provided prior to the vote
of the Issuer’s Board of Directors approving such issuance.

 

C.
Prepayments upon Change of Control. In the event of any prospective Change of Control, the Issuer, not less than thirty (30)
days and not more than sixty (60) days prior to such Change of Control, must give notice thereof to the Note Holders, and in such
notice make or cause to be made an irrevocable offer to purchase all outstanding Notes, on a Business Day on or prior to the date
such Change of Control is proposed to occur, at a purchase price equal to 100% of their principal amount plus accrued but unpaid
interest to the relevant date of purchase plus, if such notice is provided on or prior to the second anniversary of the Closing
Date, the Make Whole Premium. The offer must remain open for at least twenty (20) days following its commencement. The Issuer
shall comply with the requirements of all applicable and any other securities Laws and regulations in connection with the repurchase
of Notes pursuant to any offer to purchase described herein. Notwithstanding the above, if the Note Holders consent to
such Change of Control, the Issuer shall not be required to commence an offer to purchase the outstanding Notes and no Note Holder
will have the right to make a request for such a purchase.

subsequent to the date hereof whose appointment or election by the Board of Directors of the Issuer or
nomination for election by the Issuer’s shareholders was approved or recommended by a majority of the directors who constitute
the Incumbent Board then still in office who were either directors on the Closing Date, or whose appointment, election or nomination
for election was previously so approved or recommended, shall be considered a member of the Incumbent Board; provided,
however that the change in the composition of the Board of Directors pursuant to Section 2.01(iii) of the Stockholders’
Rights Agreement shall not constitute a Change in Control; 

 

(iii)
any sale, lease, exchange or other transfer (in one transaction or a series of transactions) of all or substantially all of the
assets of the Issuer; 

 

(iv)
any liquidation or dissolution of the Issuer or approval of any such liquidation or dissolution by the Board of Directors of the

in Dollars in immediately available funds through wire transfer to the account of the Note Holders at such place in the United
States as shall be designated in writing by the Note Holders to the Issuer from time to time (such payment instructions the “Payment

by facsimile at the number set forth in the Payment Instructions indicating the principal and interest paid and a wire transfer

of the payment of interest and fees (if applicable) hereunder or under the Notes.

 

3.6
Taxes

 

A.
Payments Free of Taxes. Any and all payments by or on account of any obligation of the Issuer under the Transaction
Documents shall be made without deduction or withholding for any Taxes, except as required by applicable Law. If any applicable
Law requires the deduction or withholding of any Tax from any such payment by the Issuer, then the Issuer shall be entitled to
make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority
in accordance with applicable Law and, if such Tax is an Indemnified Tax, then the sum payable by the Issuer shall be increased
as necessary so that, after such deduction or withholding has been made (including such deductions and withholdings applicable
to additional sums payable under this Section), the applicable Note Holder receives an amount equal to the sum it would have received
had no such deduction or withholding been made.

 

B.
Payment of Other Taxes by the Issuer. The Issuer shall timely pay to the relevant Governmental Authority in accordance with
applicable Law any Other Taxes.

 

C.
Indemnification by the Issuer. The Issuer shall indemnify each Note Holder, within ten (10) days after demand therefor, for
the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable
under this Section) payable or paid by such Note Holder or required to be withheld or deducted from a payment to such Note Holder
and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or
legally imposed or asserted by the relevant Governmental Authority. Notwithstanding the immediately preceding sentence, the Issuer
shall not be required to make payments of interest and penalties that would otherwise be included in Indemnified Taxes pursuant
to this Section 3.6 that accrue during the period described in the immediately following sentence if a Note Holder makes demand
for such payment more than 180 days after the earlier of (i) the date on which the relevant Governmental Authority makes written
demand upon such Note Holder for payment of such Indemnified Taxes, and (ii) the date on which such Note Holder has made payment
of such Indemnified Taxes. The immediately preceding sentence shall only apply to interest and penalties that accrue during the
period beginning with the first day following the applicable 180 day period described above and ending on the day the Note Holder
makes demand for payment of such Indemnified Taxes. A certificate as to the amount of such payment or liability delivered to the
Issuer by a Note Holder shall be conclusive absent manifest error.

to this Section 3.6, the Issuer shall deliver to each of the Note Holders with respect to which such Taxes were paid the original
or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting
such payment or other evidence of such payment reasonably satisfactory to each such Note Holder.

 

E.
Status of the Note Holders.

 

(i)
Any Note Holder that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any
Transaction Document shall deliver to the Issuer, at the time or times reasonably requested by the Issuer, such properly completed
and executed documentation reasonably requested by the Issuer as will permit such payments to be made without withholding or at
a reduced rate of withholding. In addition, any Note Holder, if reasonably requested by the Issuer, shall deliver such other documentation
prescribed by applicable law or reasonably requested by the Issuer as will enable the Issuer to determine whether or not such
Note Holder is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary,
a Note Holder shall not be required to deliver any form or documentation pursuant to this Section 3.6 that such Note Holder is
not legally able to deliver.

 

(ii)
Without limiting the generality of the foregoing:

 

(a) 
any Note Holder that is a U.S. Person shall deliver to the Issuer on or prior to the date on which such Note Holder becomes a
Note Holder under this Agreement (and from time to time thereafter upon the reasonable request of the Issuer), executed originals
of IRS Form W-9 certifying that such Note Holder is exempt from United States federal backup withholding tax;

 

(b)
any Foreign Note Holder shall, to the extent it is legally entitled to do so, deliver to the Issuer on or prior to the date on
which such Foreign Note Holder becomes a Note Holder under this Agreement (and from time to time thereafter upon the reasonable
request of the Issuer), whichever of the following is applicable:

respect to payments of interest under any Transaction Document, executed originals of IRS Form W-8BEN (or applicable successor
form) establishing an exemption from, or reduction of, United States federal withholding Tax pursuant to the “interest”
article of such tax treaty and (y) with respect to any other applicable payments under any Transaction Document, IRS Form W-8BEN
(or applicable successor form) establishing an exemption from, or reduction of, United States federal withholding Tax pursuant
to the “business profits” or “other income” article of such tax treaty;

 

    	-29-

    	 

    

 

(2)
executed originals of IRS Form W-8ECI;

 

(3)
in the case of a Foreign Note Holder claiming the benefits of the exemption for portfolio interest under Section 881(c) of the
Internal Revenue Code, (x) a certificate substantially in the form of Exhibit I-1 to the effect that such Foreign Note Holder
is not a “bank” within the meaning of Section 881(c)(3)(A) of the Internal Revenue Code, a “10 percent shareholder”
of the Borrower within the meaning of Section 881(c)(3)(B) of the Internal Revenue Code, or a “controlled foreign corporation”
described in Section 881(c)(3)(C) of the Internal Revenue Code (a “U.S. Tax Compliance Certificate”) and (y)
executed originals of IRS Form W-8BEN (or applicable successor form); or

 

(4)
to the extent a Foreign Note Holder is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form
W-8ECI, IRS Form W-8BEN (or applicable successor form), IRS Form W-9, U.S. Tax Compliance Certificates and/or other certification
documents from each beneficial owner, as applicable; provided that if the Foreign Note Holder is a partnership and one or more
direct or indirect partners of such Foreign Note Holder are claiming the portfolio interest exemption, such Foreign Note Holder
may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit I-2 on behalf of each such direct and indirect
partner; and

 

(c) 
if a payment made to a Note Holder under any Transaction Document would be subject to United States federal withholding Tax imposed
by FATCA if such Note Holder were to fail to comply with the applicable reporting requirements of FATCA (including those contained
in Section 1471(b) or 1472(b) of the Code, as applicable), such Note Holder shall deliver to the Issuer at the time or times prescribed
by law and at such time or times reasonably requested by the Issuer such documentation prescribed by applicable Law (including
as prescribed by Section 1471(b)(3)(C)(i) of the Internal Revenue Code) and such additional documentation reasonably requested
by the Issuer as may be necessary for the Issuer to comply with their obligations under FATCA and to determine that such Note
Holder has complied with such Note Holder’s obligations under FATCA or to determine the amount to deduct and withhold from
such payment. Solely for purposes of this clause (c), “FATCA” shall include any amendments made to FATCA after the
date of this Agreement. Each Party agrees that the Note is grandfathered and will not be subject to FATCA unless it is subsequently
modified after July 1, 2014, in a manner that will cause it to be treated as reissued for U.S. federal income tax purposes.

 

Each
Note Holder agrees that (i) if any form or certification it previously delivered becomes inaccurate in any respect, it shall update
such form or certification or promptly notify the Issuer in writing of its legal inability to do so and (ii) if any form or certification
it previously delivered becomes obsolete, it shall upon request from the Issuer update such form or certification or promptly
notify the Issuer in writing of its legal inability to do so.

 

    	-30-

    	 

    

 

F. 
Treatment of Certain Refunds. If any Note Holder determines, in its sole discretion exercised in good faith, that it has received
a refund of any Taxes as to which it has been indemnified pursuant to this Section 3.6 (including by the payment of additional
amounts pursuant to this Section 3.6), it shall pay to the Issuer an amount equal to such refund (but only to the extent of indemnity
payments made under this Section 3.6 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses
(including Taxes) of such Note Holder and without interest (other than any interest paid by the relevant Governmental Authority
with respect to such refund). The Issuer, upon the request of such Note Holder, shall repay to such Note Holder the amount paid
over pursuant to this Section 3.6F (plus any penalties, interest or other charges imposed by the relevant Governmental Authority)
in the event that such Note Holder is required to repay such refund to such Governmental Authority. Notwithstanding anything to
the contrary in this Section 3.6F, in no event will the Note Holder be required to pay any amount to the Issuer pursuant to this
Section 3.6F the payment of which would place the Note Holder in a less favorable net after-Tax position than the Note Holder
would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise
imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This Section 3.6F
shall not be construed to require any Note Holder to make available its Tax returns (or any other information relating to its
Taxes that it deems confidential) to the Issuer or any other person.

 

G.
Survival. Each Party’s obligations under this Section 3.6 shall survive any assignment of rights by a Note Holder, the
repayment, satisfaction or discharge of all obligations under any Transaction Document.

is acting as a financial advisor or fiduciary of the Issuer or any of its Subsidiaries (or in any similar capacity) with respect
to this Agreement and the Additional Transaction Documents and the transactions contemplated hereby and thereby, and any advice
given by the Note Purchaser or any of its representatives or agents in connection with the this Agreement and the Additional Transaction
Documents and the transactions contemplated hereby and thereby is merely incidental to such Note Purchaser’s purchase of

of the Issuer for purposes of the Securities Act or any applicable shareholder approval provisions, including, without limitation,
under the rules and regulations of any automated quotation system on which any of the securities of the Issuer are listed or designated.

the Securities Act or cause the offering of the Notes (or the Shares issuable upon conversion thereof) to be integrated with other
offerings for purposes of any such applicable shareholder approval provisions.

 

    	-40-

    	 

    

 

J.
SEC Documents; Financial Statements. Since December 11, 2013, the Issuer (and its predecessor) has timely filed all reports,
schedules, forms, statements and other documents required to be filed by it with the SEC pursuant to the reporting requirements
of the Exchange Act (all of the foregoing filed prior to the date hereof, and all exhibits included therein and financial statements,
notes and schedules thereto and documents incorporated by reference therein being hereinafter referred to as the “SEC
Documents”). The Issuer has delivered to the Note Purchaser or its respective representatives true, correct and complete
copies of the SEC Documents not available on the EDGAR system. As of their respective filing dates, the SEC Documents complied
in all material respects with the requirements of the Exchange Act and the rules and regulations of the SEC promulgated thereunder
applicable to the SEC Documents, and none of the SEC Documents, at the time they were filed with the SEC, contained any untrue
statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the
statements therein, in the light of the circumstances under which they were made, not misleading. As of their respective filing
dates, the financial statements of the Issuer included in the SEC Documents complied as to form in all material respects with
applicable accounting requirements and the published rules and regulations of the SEC with respect thereto. Such financial statements
have been prepared in accordance with GAAP, consistently applied, during the periods involved (except (i) as may be otherwise
indicated in such financial statements or the notes thereto, or (ii) in the case of unaudited interim statements, to the extent
they may exclude footnotes or may be condensed or summary statements) and fairly present in all material respects the financial
position of the Issuer as of the dates thereof and the results of its operations and cash flows for the periods then ended (subject,
in the case of unaudited statements, to normal year-end audit adjustments). No other information provided by or on behalf of the
Issuer to the Note Purchaser which is not included in the SEC Documents, contains any untrue statement of a material fact or omits
to state any material fact necessary in order to make the statements therein, in the light of the circumstance under which they
are or were made, not misleading (it being recognized that financial projections or forecasts by or on behalf of the Issuer are
not to be viewed as facts and that the actual results during the period or periods covered by any such financial projections or
forecasts may differ from the projected or forecasted results). The Issuer is not currently contemplating to amend or restate
any of the financial statements (including without limitation, any notes or any letter of the independent accountants of the Issuer
with respect thereto) included in the SEC Documents (the “SEC Financial Statements”), nor is the Issuer
currently aware of facts or circumstances which would require the Issuer to amend or restate any of the SEC Financial Statements,
in each case, in order for any of the SEC Financials Statements to be in compliance with GAAP and the rules and regulations of
the SEC. The Issuer has not been informed by its independent accountants that they recommend that the Issuer amend or restate
any of the SEC Financial Statements or that there is any need for the Issuer to amend or restate any of the SEC Financial Statements.

 

K.
Sarbanes-Oxley Act. The Issuer is in compliance with any and all requirements of the Sarbanes-Oxley Act of 2002, as amended,
that are effective as of the date hereof and are applicable to the Issuer as of the date hereof, and any and all applicable rules
and regulations promulgated by the SEC thereunder that are effective as of the date hereof. 

 

L.
Transactions With Affiliates. Except as disclosed in the SEC Documents or on Schedule 5.2L, as of the Closing Date, none of
the officers, directors or employees of the Issuer or any other Subject Company is a party to any transaction with the Issuer
or any other Subject Company (other than for ordinary course services as employees, officers or directors), including any contract,
agreement or other arrangement providing for the furnishing of services to or by, providing for rental of real or personal property
to or from, or otherwise requiring payments to or from any such officer, director or employee or, to the knowledge of the Issuer
or any other Subject Company, any corporation, partnership, trust or other entity in which any such officer, director, or employee
has a substantial interest or is an officer, director, trustee or partner. 

 

    	-41-

    	 

    

 

M.
Internal Accounting and Disclosure Controls. The Issuer and each of its Subsidiaries maintain a system of internal accounting
controls sufficient to provide reasonable assurance that, (i) transactions are executed in accordance with management’s
general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements
in conformity with GAAP and to maintain asset and liability accountability, (iii) access to assets or incurrence of liabilities
is permitted only in accordance with management’s general or specific authorization, and (iv) the recorded accountability
for assets and liabilities is compared with the existing assets and liabilities at reasonable intervals and appropriate action
is taken with respect to any difference. The Issuer maintains disclosure controls and procedures (as such term is defined in Rule
13a-15 under the Exchange Act) that are effective in ensuring that information required to be disclosed by the Issuer in the reports
that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified
in the rules and forms of the SEC, including controls and procedures designed to ensure that information required to be disclosed
by the Issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Issuer’s
management, including its principal executive officer or officers and its principal financial officer or officers, as appropriate,
to allow timely decisions regarding required disclosure. Except as disclosed in the SEC Documents, during the twelve months prior
to the date hereof neither the Issuer nor any of its Subsidiaries has received any notice or correspondence from any accountant
relating to any material weakness in any part of the system of internal accounting controls of the Issuer or any of its Subsidiaries.

 

N.
Off Balance Sheet Arrangements. Except as set forth in the SEC Documents, there is no transaction, arrangement, or other relationship
between the Issuer and an unconsolidated or other off balance sheet entity that is required to be disclosed by the Issuer in its
Exchange Act filings and is not so disclosed or that otherwise would be reasonably likely to have a Material Adverse Effect.

or continuing any conduct or practice in connection with such activity;

(v)
a finding by a court of competent jurisdiction in a civil action or by the SEC or other authority to have violated any securities
law, regulation or decree and the judgment in such civil action or finding by the SEC or any other authority has not been subsequently
reversed, suspended or vacated; or

 

(vi)
a finding by a court of competent jurisdiction in a civil action or by the Commodity Futures Trading Commission to have violated
any federal commodities law, and the judgment in such civil action or finding has not been subsequently reversed, suspended or

P. 
No Disagreements with Accountants and Lawyers. There are no material disagreements of any kind presently existing, or reasonably
anticipated by the Issuer to arise, between the Issuer and the accountants and lawyers formerly or presently employed by the Issuer
and the Issuer is current with respect to any fees owed to its accountants and lawyers which could affect the Issuer’s ability
to perform any of its obligations under the Transaction Documents. In addition, on or prior to the date hereof, the Issuer had
discussions with its accountants about its financial statements previously filed with the SEC. Based on those discussions, the
Issuer has no reason to believe that it will need to restate any such financial statements or any part thereof.

 

    	-43-

    	 

    

 

Q.
No Disqualification Events. With respect to Notes (and the Shares issuable upon conversion thereof) to be offered and sold
hereunder in reliance on Regulation D Securities, none of the Issuer, any of its predecessors, any affiliated issuer, any director,
executive officer, other officer of the Issuer participating in the offering hereunder, any beneficial owner of 20% or more of
the Issuer’s outstanding voting equity securities, calculated on the basis of voting power, nor any promoter (as that term
is defined in Rule 405 under the Securities Act) connected with the Issuer in any capacity at the time of sale (collectively “Issuer
Covered Persons”) is subject to any of the “Bad Actor” disqualifications described in Rule 506(d)(1)(i)
to (viii) under the Securities Act (a “Disqualification Event”), except for a Disqualification Event covered
by Rule 506(d)(2) or (d)(3) under the Securities Act. The Issuer has exercised reasonable care to determine whether any Issuer
Covered Person is subject to a Disqualification Event. The Issuer has complied, to the extent applicable, with its disclosure
obligations under Rule 506(e), and has furnished to the Note Purchaser a copy of any disclosures provided thereunder.

 

R.
Other Covered Persons. Except as disclosed on Schedule 5.2R, the Issuer is not aware of any Person that has been or will be

case is material in relation to the business, operations, properties, assets or condition (financial or otherwise) of the Subject
Companies, taken as a whole.

 

5.4
No Changes.

 

Since
December 31, 2013, no event or change has occurred with respect to any Subject Company that has caused or could reasonably be
expected to cause, a Material Adverse Effect.

Each
of the Subject Companies has good, marketable and legal title (or in the case of leased properties and assets, good, marketable
and legal leasehold interests) to all of its respective properties and assets, including all its real and personal properties
material to its business, in each case, free and clear of all Liens, other than Permitted Liens (except as otherwise consented
to by the Note Holders) and except to the extent that the failure to have such title could not reasonably be expected to have,
individually or in the aggregate, a Material Adverse Effect. All Lien searches have been conducted consistent with the policy
of the Issuer and to the best of the Issuer’s knowledge, indicate that the properties and assets are free of Liens, and
to the extent any such Liens exist, such Liens could not reasonably be expected to result in a Material Adverse Effect.

may be added thereto for non-payment thereof except for those being contested in accordance with Permitted Contest Procedures

the aggregate), and no condition exists that, with the giving of notice or the lapse of time or both, would constitute such a
default.

9.1 Registration
and Transfer of the Notes

 

A. Register.
The Notes shall be issued in registered form. The Issuer shall keep at its principal office a register for the registration and
transfers of the Notes. The name and address of each holder of the Notes, the principal amount (and stated interest) of the Notes
held by each Note Holder, each transfer thereof and the name and address of each transferee of the Notes shall be set out in such
register. Prior to due presentment for registration of transfer, the Person in whose name any Note shall be registered shall be
deemed and treated as the owner and holder thereof for all purposes hereof. This Section 9.1A shall be construed so that the Notes
are at all times maintained in “registered form” within the meaning of Sections 163(f), 871(h)(2) and 881(c)(2) of
the Internal Revenue Code. The Issuer shall give to any Note Holder promptly upon request therefor, a complete and correct copy
of the names and addresses of all registered holders of Notes. Any registered holder of the Notes shall be considered to be a

purchaser, assignee, transferee or participant has provided to the Issuer representations and warranties in the form of Section

shall have a right to consent or vote on any matters hereunder other than with respect to:

 

(a) the extension
of any date of any payment of principal or interest in respect of any Note;

it enters the name and address of each participant and the principal amounts (and stated interest) of each participant’s
interest in the Notes (the “Participant Register”), and (ii) obtain from each Participant the documentation
prescribed by Section 3.6E as if such participant were a Note Holder; provided that no Note Holder shall have any obligation to
disclose all or any portion of the Participant Register (including the identity of any participant or any information relating
to a participant’s interest in any loans) to any Person except to the extent that such disclosure is necessary to establish
that such loan is in registered form under Treasury Regulation Section 5f.103-1(c). The entries in the Participant Register shall
be conclusive absent manifest error, and such Note Holder shall treat each person whose name is recorded in the Participant Register
as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary.

A. In
addition to the payment of expenses pursuant to Section 9.2, the Issuer agrees to defend (subject to Indemnitees’ selection
of counsel), indemnify, pay and hold harmless each Note Holder and its Affiliates and its respective officers, directors, employees,
beneficiaries, shareholders and agents (collectively called the “Indemnitees”) from and against any and all
other Indemnified Liabilities; provided that the Issuer shall not have any obligation to any Indemnitee hereunder with
respect to any Indemnified Liabilities to the extent such Indemnified Liabilities arise from (i) the gross negligence or willful
misconduct of that Indemnitee as determined by a final judgment of a court of competent jurisdiction or (ii) a dispute among Indemnitees
not arising from the actions or omissions of the Issuer. In no event shall any Indemnitee be liable to the Issuer for any consequential,

party thereto, and any fees or expenses incurred by Indemnitees in enforcing this indemnity), and whether based on any federal,
state, or foreign Laws (including securities and commercial Laws and Environmental Laws), on common Law or equitable cause or
on contract or otherwise, that may be imposed on, incurred by, or asserted against any such Indemnitee, in any manner relating
to or arising out of:

activity, operation, land ownership or practice of the Issuer or any other Subject Company.

 

C. To
the extent that the undertaking to indemnify, pay and hold harmless set forth in Section 9.3A above may be unenforceable because
it is violative of any applicable Law or public policy, the Issuer shall contribute the maximum portion which it is permitted
to pay and satisfy under applicable Law to the payment and satisfaction of all Indemnified Liabilities incurred by the Indemnitees
or any of them.

Sharing 

 

A. The
Note Holders hereby agree among themselves that if any of them shall, whether by voluntary payment, by realization upon security,

any right under the Transaction Documents or otherwise, or as adequate protection of a deposit treated as cash collateral under
the Bankruptcy Code or any similar law, receive payment or reduction of a proportion of the aggregate amount of principal, interest,
fees and other amounts then due and owing to that Note Holder hereunder or under the other Transaction Documents (collectively,
the “Aggregate Amounts Due” to such Note Holder) which is greater than the proportion received by any other

greater payment shall:

 

(i) notify each
other Note Holder of the receipt of such payment; and

 

(ii) apply a
portion of such payment to purchase participations (which it shall be deemed to have purchased from each seller of a participation

Holders so that all such recoveries of Aggregate Amounts Due shall be shared by all Note Holders in proportion to the Aggregate
Amounts Due to them,

 

provided that
if all or part of such proportionately greater payment received by such purchasing Note Holder is thereafter recovered from such
Note Holder upon the bankruptcy or reorganization of the Issuer or otherwise, those purchases shall be rescinded and the purchase
prices paid for such participations shall be returned to such purchasing Note Holder ratably to the extent of such recovery, but
without interest.

 

    	-76-

    	 

    

 

B. The
Issuer expressly consents to the arrangement contemplated in Section 9.15A and agrees that any holder of a participation so purchased

term and reserves the right to dispose of the Notes at any time in accordance with or pursuant to a registration statement or
an exemption under the Securities Act and in accordance with the terms of this Agreement and the Additional Transaction Documents.
Such Note Purchaser is acquiring the Notes hereunder in the ordinary course of its business. Such Note Purchaser does not presently
have any agreement or understanding, directly or indirectly, with any Person to distribute any of the Notes (or the Shares issuable

offered and sold to it in reliance on specific exemptions from the registration requirements of United States federal and state
securities Laws and that the Issuer is relying in part upon the truth and accuracy of, and such Note Purchaser’s compliance

Issuer’s representations and warranties contained herein. Such Note Purchaser understands that its investment in the Notes
(and the Shares issuable upon conversion thereof) involves a high degree of risk. Such Note Purchaser has sought such accounting,
legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of
the Notes (and the Shares issuable upon conversion thereof).

 

F. No Governmental
Review. Such Note Purchaser understands that no United States federal or state agency or any other government or governmental
agency has passed on or made any recommendation or endorsement of the Notes (or the Shares issuable upon conversion thereof) or
the fairness or suitability of the investment in the Notes (or the Shares issuable upon conversion thereof) nor have such authorities
passed upon or endorsed the merits of the offering of the Notes (or the Shares issuable upon conversion thereof).

Purchaser provides the Issuer with reasonable assurance that such Securities can be sold, assigned or transferred pursuant to
Rule 144;

 

(ii) any sale
of the Securities made in reliance on Rule 144 may be made only in accordance with the terms of Rule 144 and further, if Rule
144 is not applicable, any resale of the Notes or Shares issuable upon conversion thereof under circumstances in which the seller
(or the Person through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the Securities Act)
may require compliance with some other exemption under the Securities Act or the rules and regulations of the SEC promulgated
thereunder; and

 

(iii) neither
the Issuer nor any other Person is under any obligation to register the Notes or the Shares issuable upon conversion thereof under
the Securities Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder.

 

H. Legends.
Such Note Purchaser understands that the certificates or other instruments representing the Notes and, until such time as the
resale of the Shares issuable upon conversion of the Notes have been registered under the Securities Act as contemplated by the
Registration Rights Agreement, the stock certificates representing any Shares issued upon conversion of the Notes, except as set
forth below, shall bear any legend as required by the “blue sky” laws of any state and a restrictive legend in substantially
the following form (and a stop-transfer order may be placed against transfer of such stock certificates):

 

NEITHER THE
ISSUANCE AND SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE CONVERTIBLE
HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT
BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES
UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF COUNSEL, IN A GENERALLY ACCEPTABLE FORM, THAT REGISTRATION
IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT. NOTWITHSTANDING THE FOREGOING,
THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY
THE SECURITIES.

 

    	-80-

    	 

    

 

The legend set
forth above shall be removed and the Issuer shall issue a certificate without such legend to the holder of the Notes or Shares
issued upon conversion of the Notes upon which it is stamped or issue to such holder by electronic delivery at the applicable
balance account at DTC, if, unless otherwise required by state securities laws, (i) such Notes or Shares issued upon conversion
of the Notes are registered for resale under the Securities Act, (ii) in connection with a sale, assignment or other transfer,
such holder provides the Issuer with an opinion of counsel, in a generally acceptable form, to the effect that such sale, assignment
or transfer of the Notes or Shares issued upon conversion of the Notes may be made without registration under the applicable requirements
of the Securities Act, or (iii) the Notes or Shares issued upon conversion of the Notes can be sold, assigned or transferred pursuant
to Rule 144. The Issuer shall be responsible for the fees of its transfer agent and all DTC fees associated with such issuance.

 

I. Validity;
Enforcement. This Agreement and the Additional Transaction Documents to which the Note Purchaser is a party have been duly
and validly authorized, executed and delivered on behalf of such Note Purchaser and shall constitute the legal, valid and binding
obligations of such Note Purchaser enforceable against such Note Purchaser in accordance with their respective terms, except as
such enforceability may be limited by general principles of equity or to applicable bankruptcy, insolvency, reorganization, moratorium,
liquidation and other similar laws relating to, or affecting generally, the enforcement of applicable creditors’ rights
and remedies.

 

J. No Conflicts.
The execution, delivery and performance by such Note Purchaser of this Agreement and the Additional Transaction Documents to which
the Note Purchaser is a party and the consummation by such Note Purchaser of the transactions contemplated hereby and thereby
will not, (i) result in a violation of the organizational documents of such Note Purchaser, (ii) conflict with, or constitute
a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights
of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which such Note Purchaser
is a party, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state
securities laws) applicable to such Note Purchaser, except in the case of clauses (ii) and (iii) above, for such conflicts, defaults,
rights or violations which would not, individually or in the aggregate, reasonably be expected to have a material adverse effect
on the ability of such Note Purchaser to perform its obligations hereunder.

 

K. Residency.
Such Note Purchaser is a resident of the jurisdiction specified below its address on the signature pages hereto.

 

    	-81-

    	 

    

 

L. Experience
of the Note Purchaser. Such Note Purchaser, either alone or together with its representatives, has such knowledge, sophistication
and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment
in the Notes and the Shares issuable upon conversion thereof, and has so evaluated the merits and risks of such investment. Such
Note Purchaser is able to bear the economic risk of an investment in the Notes and the Shares issuable upon conversion thereof
and is able to afford a complete loss of such investment.

 

M. Plan Assets;
Prohibited Transactions. Either:

 

(i) the Note
Purchaser is not, and is not using assets of, a Benefit Plan Investor or of a governmental, church or non-U.S. plan that is subject
to any federal, state, local or non-U.S. law that is substantially similar to the provisions of Section 406 of ERISA or Section
4975 of the Internal Revenue Code (“Similar Law”) or any entity whose assets are treated as assets of any such
plan to purchase the Notes and Common Stock; or

 

(ii) the purchase
and holding of any Notes or any interest therein and the acquisition of any Common Stock or any interest therein will not result
in a non-exempt prohibited transaction under Section 406 of ERISA, Section 4975 of the Internal Revenue Code or any Similar Law.

Obligations, whether as a “voidable preference,” “fraudulent conveyance,” any settlement or compromise
with any Person (including the Issuer) in respect of such payment or otherwise, or otherwise, all as though such payment or performance
had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Obligations
shall be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

Calculation
of Make Whole Premium

 

The “Make-Whole Premium”
shall equal an amount (which shall not be less than zero), calculated by the Note Holders as of the date of the Prepayment Notice
(or other date as of which the Make Whole Premium has become payable), equal to (i) the IRR Target Amount (as defined below) minus
(ii) all amounts to be received by the Note Holders under the Notes (including payments of principal and interest, but
net of fees and commissions, withholding taxes or other similar expenses) following payment in full of the outstanding principal
amount of the Notes in accordance with the terms of the Agreement.

 

“IRR Target Amount”
means the amount that yields to Note Purchaser an internal rate of return of twenty-one percent (21%) on the Commitment, calculated
using the XIRR function in Microsoft Excel and assuming all Advances are fully drawn as of the Closing Date in the full amount
of the Commitment, notwithstanding the actual dates on which the Advances are made.

on the Business Day of and not more than ten (10) calendar days prior to the proposed conversion date (the “Conversion
Date”). The Issuer shall notify the Payee and each other Note Holder of the receipt of any such election within two
(2) Business Days after receipt thereof. Any conversion pursuant to this Section  7 will
be effective as of the Conversion Date. The initial “Conversion Rate” is 166.66667 Shares per $1,000 principal
amount of the Notes, provided that in the event that the Buyers (as defined in the Option Agreement) fail to exercise the Option
within the time period provided for the in Option Agreement, the Conversion Rate shall automatically be adjusted to 142.85714
Shares per $1,000 principal amount of the Notes. The Conversion Rate shall be subject to further adjustment as provided in Section
8. If the Note Holders exercise their conversion rights, at the Conversion Date:

 

    	Exhibit A Form of Note	2	 

    	 

    

 

(i) the Payee
shall record the principal amount so converted on its books and on Schedule 1;

 

(ii) the Payee
shall be deemed to be the record holder of the number of fully paid and non-assessable Shares determined in accordance with this
Section 7;

 

(iii) appropriate
entries evidencing such ownership shall be made in the Issuer’s books and records; and

 

(iv) the Issuer
shall, on the Conversion Date, deliver to the Payee a certificate or certificates for the number of Shares to which the Payee
is entitled.

 

(b) No fractional
Share shall be issuable upon conversion.

 

(c)
All principal and interest that is converted into the Shares pursuant to this Section  7
will no longer be outstanding or due and payable from the Issuer and will be deemed to have been fully paid and satisfied on the
Conversion Date and the Issuer shall thereafter have no further obligation or liability with respect to such principal and interest.
Subject to the terms and conditions of the Convertible Note Agreement, the conversion of outstanding principal amounts under this
Note (and the other Notes) shall not affect the availability of subsequent Advances under the Notes, and, at the option of the
Note Holders, the Notes may be converted from time to time with respect to the remaining Advances thereunder.

 

8. Adjustment
of Conversion Rate. The “Conversion Rate” is subject to adjustment as provided in this Section 8. The Conversion Rate
shall be subject to adjustments, calculated by the Issuer, from time to time as follows:

 

(a) In case
the Issuer shall hereafter pay a dividend or make a distribution to all holders of outstanding Common Stock in Common Stock, the
Conversion Rate in effect at the opening of business on the date following the date fixed for the determination of shareholders
entitled to receive such dividend or other distribution shall be increased by multiplying such Conversion Rate by a fraction:

 

(i) the numerator
of which shall be the sum of the number of shares of Common Stock outstanding at the close of business on the record date fixed
for such determination and the total number of shares constituting such dividend or other distribution; and

 

(ii) the denominator
of which shall be the number of shares of Common Stock outstanding at the close of business on the record date fixed for such
determination.

 

Such increase
shall become effective immediately after the opening of business on the Business Day following the record date. If any dividend
or distribution of the type described in this Section 8(a) is declared but not so paid or made, the Conversion Rate shall again
be adjusted to the Conversion Rate which would then be in effect if such dividend or distribution had not been declared.

 

    	Exhibit A Form of Note	3	 

    	 

    

 

(b) In case
the outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Rate
in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately
increased, and conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of shares of Common
Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such combination becomes
effective shall be proportionately reduced. In each such case, the Conversion Rate shall be adjusted by multiplying such Conversion
Rate by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately after giving
effect to such subdivision or combination and the denominator of which shall be the number of shares of Common Stock outstanding
immediately prior to such subdivision or combination. Such reduction or increase, as the case may be, shall become effective immediately
after the opening of business on the day following the day upon which such subdivision or combination becomes effective.

 

(c) In case
the Issuer shall issue rights or warrants to all holders of its outstanding shares of Common Stock entitling them to subscribe
for or purchase shares of Common Stock (or securities convertible into shares of Common Stock) at a price per share (or having
a conversion price per share) less than the Current Market Price per share of Common Stock on the record date fixed for the determination
of shareholders entitled to receive such rights or warrants, the Conversion Rate shall be adjusted so that the same shall equal
the price determined by multiplying the Conversion Rate in effect at the opening of business on the date after such record date
by a fraction:

 

(i) the numerator
of which shall be the number of shares of Common Stock outstanding on the close of business on the record date plus the total
number of additional shares of Common Stock so offered for subscription or purchase (or into which the convertible securities
so offered are convertible) at such below Current Market Price, and

 

(ii) the denominator
of which shall be the number of shares of Common Stock outstanding at the close of business on the record date plus the number
of shares which the aggregate offering price of the total number of shares so offered for subscription or purchase (or the aggregate
Conversion Price of the convertible securities so offered) would purchase at such Current Market Price.

 

Such adjustment
shall be successively made whenever any such rights or warrants are issued and shall become effective immediately after the opening
of business on the day following the record date fixed for determination of shareholders entitled to receive such rights or warrants.
To the extent that shares of Common Stock (or securities convertible into shares of Common Stock) are not delivered pursuant to
such rights or warrants, upon the expiration or termination of such rights or warrants the Conversion Rate shall be readjusted
to the Conversion Rate which would then be in effect had the adjustments made upon the issuance of such rights or warrants been
made on the basis of the delivery of only the number of shares of Common Stock (or securities convertible into shares of Common
Stock) actually delivered. In the event that such rights or warrants are not so issued, the Conversion Rate shall again be adjusted
to be the Conversion Rate which would then be in effect if such date fixed for the determination of shareholders entitled to receive
such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for
or purchase shares of Common Stock at less than such Current Market Price, and in determining the aggregate offering price of
such shares of Common Stock, there shall be taken into account any consideration received for such rights or warrants, the value
of such consideration if other than cash, to be determined by the Board of Directors.

 

    	Exhibit A Form of Note	4	 

    	 

    

 

(d) In case
the Issuer shall, by dividend or otherwise, distribute to all holders of its shares of Common Stock of any class of capital stock
of the Issuer (other than any dividends or distributions to which Section 8(a) applies) or evidences of its indebtedness or other
assets, including securities, but excluding, (1) any rights or warrants referred to in Section 8(c), (2) any dividends or distributions
in connection with a reclassification, change of the Issuer’s shares of Common Stock, merger, consolidation, statutory share
exchange, combination, sale or conveyance, and (3) dividends and distributions paid exclusively in cash referred to in Section
8(e) (the securities described in foregoing clauses (1), (2) and (3) hereinafter in this Section 8(d) called the “excluded
securities”), then, in each such case, subject to the second succeeding paragraph of this Section 8(d), the Conversion Rate
shall be adjusted so that the same shall be equal to the price determined by multiplying the Conversion Rate in effect immediately
prior to the close of business on the record date with respect to such distribution by a fraction:

 

(i) the numerator
of which shall be such Current Market Price per share of Common Stock on the record date, and

 

(ii) the denominator
of which shall be the Current Market Price per share of Common Stock on such date, less the then fair market value (as determined
by the Board of Directors, whose determination shall be conclusive and set forth in a board resolution) on such date of the portion
of the securities, evidences of indebtedness or other assets so distributed (other than excluded securities) applicable to one
share of Common Stock (determined on the basis of the number of shares of shares of Common Stock outstanding on the record date).

 

Such increase
shall become effective immediately prior to the opening of business on the day following the record date. However, in the event
that the then fair market value (as so determined) of the portion of the securities, evidences of indebtedness or other assets
so distributed (other than excluded securities) applicable to one share of Common Stock is equal to or greater than the Current
Market Price on the record date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Note Holder
shall have the right to receive upon conversion of the Notes (or any portion thereof) the amount of securities, evidences of indebtedness
or other assets so distributed (other than excluded securities) that such Note Holder would have received had such Note Holder
converted such Notes (or portion thereof) immediately prior to such record date. In the event that such dividend or distribution
is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if
such dividend or distribution had not been declared.

 

If the Board
of Directors determines the fair market value of any distribution for purposes of this Section 8(d) by reference to the actual
or when issued trading market for any securities comprising all or part of such distribution (other than excluded securities),
it must in doing so consider the prices in such market over the same period (the “Reference Period”) used in
computing the Current Market Price pursuant to Section 8(g) to the extent possible, unless the Board of Directors in a board resolution
determines in good faith that determining the fair market value during the Reference Period would not be in the best interests
of the Note Holder.

 

    	Exhibit A Form of Note	5	 

    	 

    

 

For purposes
of Sections 8(a) through 8(d), any dividend or distribution to which this Section 8(d) is applicable that also includes share
of Common Stock, a subdivision or combination of share of Common Stock to which Section 8(b) applies, or rights or warrants to
subscribe for or purchase shares of Common Stock (or securities convertible into shares of Common Stock) to which Section 8(c)
applies (or any combination thereof), shall be deemed instead to be:

 

(1) a dividend
or distribution of the evidences of indebtedness, assets, shares of capital stock, rights or warrants other than such share of
Common Stock, such subdivision or combination or such rights or warrants to which Sections 8(a) through 8(c) apply, respectively
(and any Conversion Rate increase required by this Section 8(d) with respect to such dividend or distribution shall then be made),
immediately followed by:

 

(2) a dividend
or distribution of such share of Common Stock, such subdivision or combination or such rights or warrants (and any further Conversion
Rate increase required by Sections 8(a) through 8(c) with respect to such dividend or distribution shall then be made), except:

 

(A) the record
date of such dividend or distribution shall be substituted as (x) “the date fixed for the determination of shareholders
entitled to receive such dividend or other distribution”, “record date fixed for such determinations” and “record
date” within the meaning of Section 8(a), (y) “the day upon which such subdivision becomes effective” and “the
day upon which such combination becomes effective” within the meaning of Section 8(b), and (z) as “the date fixed
for the determination of shareholders entitled to receive such rights or warrants”, “the record date fixed for the
determination of the shareholders entitled to receive such rights or warrants” and such “record date” within
the meaning of Section 8(c), and

 

(B) any shares
of Common Stock included in such dividend or distribution shall not be deemed “outstanding at the close of business on the
date fixed for such determination” within the meaning of Section 8(a) and any increase or reduction in the number of shares
of Common Stock resulting from such subdivision or combination shall be disregarded in connection with such dividend or distribution.

 

(e) In case
the Issuer shall, by dividend or otherwise, distribute to all holders of its shares of Common Stock, cash, then and in each such
case, immediately after the close of business on such date, the Conversion Rate shall be increased so that the same shall equal
the price determined by multiplying the Conversion Rate in effect immediately prior to the close of business on such record date
by a fraction:

 

(i) the numerator
of which shall be equal to the Current Market Price on such record date, and

 

(ii) the denominator
of which shall be equal to the Current Market Price on the record date less an amount equal to the quotient of (x) the aggregate
amount of the cash distributed and (y) the number of shares of Common Stock outstanding on the record date.

 

    	Exhibit A Form of Note	6	 

    	 

    

 

In the event
that such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate
which would then be in effect if such dividend or distribution had not been declared.

 

(f) In case
the Issuer or any of its Subsidiaries pays holders of the shares of Common Stock in respect of a tender offer or exchange offer,
other than an odd-lot offer, by the Issuer or any of its Subsidiaries for shares of Common Stock to the extent that the cash and
fair market value of any other consideration included in the payment per share of Common Stock exceeds the Sale Price per share
of Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender
offer or exchange offer (the “Expiration Time”), then, and in each such case, the Conversion Rate shall be adjusted
so that the same shall equal the price determined by multiplying the Conversion Rate in effect immediately prior to close of business
on the date of the Expiration Time by a fraction:

 

(i) the numerator
of which shall be the sum of (x) the fair market value (determined as aforesaid) of the aggregate consideration payable to shareholders
based on the acceptance (up to any maximum specified in the terms of the tender offer or exchange offer) of all shares validly
tendered or exchanged and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being
referred to as the “Purchased Shares”) and (y) the product of the number of shares of Common Stock outstanding (less
any Purchased Shares) at the Expiration Time and the Sale Price of the shares of Common Stock on the Trading Day next succeeding
the Expiration Time, and

 

(ii) the denominator
of which shall be the number of shares of Common Stock outstanding (including any tendered or exchanged shares) at the Expiration
Time multiplied by the Sale Price of the shares of Common Stock on the Trading Day next succeeding the Expiration Time.

 

Such increase
(if any) shall become effective immediately prior to the opening of business on the day following the Expiration Time. In the
event that the Issuer is obligated to purchase shares pursuant to any such tender offer or exchange offer, but the Issuer is permanently
prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Rate shall again
be adjusted to be the Conversion Rate which would then be in effect if such tender offer or exchange offer had not been made.

 

(g) For purposes
of this Section 8, the following terms shall have the meanings indicated:

 

“Current
Market Price” shall mean the average of the daily Sale Prices per share of Common Stock for the ten consecutive Trading
Days ending not later than the earlier of the date immediately prior to the date in question and the day before the “ex”
date with respect to the issuance, distribution, subdivision or combination requiring such computation. If another issuance, distribution,
subdivision or combination to which Section 8 applies occurs during the period applicable for calculating “Current Market
Price” pursuant to the preceding definition, then “Current Market Price” shall be appropriately adjusted to
reflect the impact of such issuance, distribution, subdivision or combination on the Sale Price of the share of Common Stock during
such period. For purposes of this paragraph, the term “ex” date, when used:

 

    	Exhibit A Form of Note	7	 

    	 

    

 

(A) with respect
to any issuance or distribution, means the first date on which the shares of Common Stock trades regular way on the relevant exchange
or in the relevant market from which the Sale Price was obtained without the right to receive such issuance or distribution;

 

(B) with respect
to any subdivision or combination of shares of Common Stock, means the first date on which the shares of Common Stock trades regular
way on such exchange or in such market after the time at which such subdivision or combination becomes effective, and

 

(C) with respect
to any tender or exchange offer, means the first date on which the shares of Common Stock trades regular way on such exchange
or in such market after the Expiration Time of such offer.

 

Notwithstanding
the foregoing, whenever successive adjustments to the Conversion Rate are called for pursuant to this Section 8, such adjustments
shall be made to the Current Market Price as may be necessary or appropriate to effectuate the intent of this Section 8 and to
avoid unjust or inequitable results as determined in good faith by the Board of Directors.

 

(2) “fair
market value” shall mean the amount which a willing buyer would pay a willing seller in an arm’s length transaction.

 

(3) “record
date” shall mean for purposes of this Section 8, with respect to any dividend, distribution or other transaction or
event in which the holders of shares of Common Stock have the right to receive any cash, securities or other property or in which
the shares of Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities
or other property, the date fixed for determination of shareholders entitled to receive such cash, securities or other property
(whether such date is fixed by the Board of Directors or by statute, contract or otherwise).

 

(4) “Sale
Price” as of any date means the closing per share sale price (or if no closing sale price is reported, the average of
the bid price and ask prices or, if more than one in either case, the average of the average bid and average ask prices) on such
date on the principal United States securities exchange on which the shares of Common Stock are traded or, if the shares of Common
Stock are not listed on a United States national or regional securities exchange, as reported by the OTC Bulletin Board or successor
thereto or by Pink Sheets LLC or a successor thereto. In the absence of a quotation, the Board of Directors of the Issuer will
determine the sale price on the basis of such quotations as the Board of Directors in good faith considers appropriate.

 

(h) The Issuer
may make such increases in the Conversion Rate, in addition to those required by any of Sections 8(a) through (f), as the Board
of Directors considers to be advisable to avoid or diminish any income Tax to holders of shares of Common Stock or rights to purchase
shares of Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated
as such for income Tax purposes.

 

    	Exhibit A Form of Note	8	 

    	 

    

 

(i) All calculations
under this Section 8 shall be made by the Issuer and shall be made to the nearest cent or to the nearest one hundredth of a share,
as the case may be. No adjustment need be made for a change in the par value or no par value of the shares of Common Stock. No
adjustment in the Conversion Rate shall be required if the holders of the Notes participate in the transactions that would otherwise
lead to an adjustment in the Conversion Rate pursuant to this Section 8.

 

(j) In any
case in which this Section 8 provides that an adjustment shall become effective immediately after a record date for an event,
the Issuer may defer until the occurrence of such event, (i) issuing to the holder of any Notes converted after such record date
and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by reason of the adjustment
required by such event over and above the shares of Common Stock issuable upon such conversion before giving effect to such adjustment,
and (ii) paying to such holder of Notes any amount in cash in lieu of fractional shares of Common Stock.

 

(k) For purposes
of this Section 8, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury
of the Issuer. The Issuer will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of
the Issuer.

 

9. THIS NOTE
AND THE RIGHTS AND OBLIGATIONS OF THE ISSUER AND THE PAYEE HEREUNDER SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED
IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK (INCLUDING SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW OF THE
STATE OF NEW YORK), WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES WHICH WOULD RESULT IN THE APPLICATION OF THE LAWS OF ANOTHER
JURISDICTION.

 

10. Upon the
occurrence of an Event of Default, the unpaid balance of the principal amount of this Note, together with all accrued and unpaid
interest thereon, may become, or may be declared to be, due and payable in the manner, upon the conditions and with the effect

and accompanied by the address for notices and payment instructions of each transferee of such Note or part thereof and a representation
by each such transferee that such transferee is a Permitted Transferee), the Issuer shall execute and deliver, at the Issuer’s
