if that default:


 


(A)         results
in such indebtedness becoming or being declared due and payable (prior to its express maturity); or


 


(B)         constitutes
a failure to pay the principal of, or interest on, such indebtedness when due and payable at its stated maturity, upon required

a voluntary case;


 


(B)         consents

Irrelevant. Each of the events enumerated in Section 6.01(a) will constitute an Event of Default whatever the cause
and regardless of whether voluntary or involuntary or effected by operation of law or pursuant to any judgment, decree or order
of any court or any order, rule or regulation of any administrative or governmental body.


 


Section
6.02         Acceleration.


 


(a)          Automatic
Acceleration in Certain Circumstances. If an Event of Default specified in Sections 6.01(a)(ix) or 6.01(a)(x)
occurs with respect to the Company, the principal amount of, and all accrued and unpaid interest, if any, on this Note will immediately
become due and payable without any further action or notice by any party.


 


(b)          Optional
Acceleration. If any Event of Default other than an Event of Default specified in Section 6.01(a)(ix) or 6.01(a)(x)
occurs and is continuing, the holders of at least 25% of the aggregate principal amount of the Series then outstanding, by delivering
a written notice to the Company, may declare the principal amount of, and all accrued and unpaid interest, if any, on all then
outstanding notes in the Series immediately due and payable, and upon such declaration, the principal amount of, and all accrued
and unpaid interest, if any, on all then outstanding notes in the Series will immediately become due and payable.


 


(c)          Rescission
of Acceleration. Notwithstanding anything to the contrary in this Note, holders of a majority of the aggregate principal amount
of the Series then outstanding may, on behalf of the holders of all then outstanding notes in the Series, rescind any acceleration
of such notes and its consequences hereunder by delivering written notice to the Company if (i) such rescission would not conflict
with any judgment or decree of a court of competent jurisdiction; and (ii) all existing Events of Default (other than the nonpayment
of the principal of, interest, if any, on, or the Fundamental Change Repurchase Price for, the notes in the Series that have become
due solely as a result of acceleration) have been cured or waived. No such rescission will affect any subsequent Default or impair
any right consequent thereto.


 


Section 6.03         Other
Remedies. If an Event of Default occurs and is continuing, the Holder may pursue any available remedy to collect the payment
of principal, accrued and unpaid interest, if any, or payment of the Fundamental Change Repurchase Price for, this Note or to enforce
the performance of any provision of this Note regarding any other matter.


 




    	 	- 20 -	 



     


    

 


A delay or omission by the Holder in exercising
any right or remedy accruing upon an Event of Default will not impair the right or remedy or constitute a waiver of or acquiescence
in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative.


 


Section
6.04         Sole Remedy for Failure to Report.


 


(a)          General.
Notwithstanding anything to the contrary in this Note, the Company may elect that the sole remedy for any Event of Default specified
in Section 6.01(a)(vi) relating to the Company’s failure to comply with Section 4.03 (a “Reporting
Event of Default”) will, for the period beginning on the date on which such Reporting Event of Default first occurred
and ending on the earlier of (A) the date on which such Reporting Event of Default (i) is cured; or (ii) is validly waived in accordance
with Section 6.05; and (B) the sixtieth (60th) calendar day immediately following the date on which such Reporting Event
of Default first occurred, consist exclusively of the right to receive additional interest (the “Special Interest”)
on this Note at a rate equal to 0.50% per annum on the principal amount of this Note. Any Special Interest will be payable in the
same manner and on the same dates as the stated interest payable on this Note and will accrue in addition to any Additional Interest
that the Company is obligated to pay.


 


(b)          Limitation
on Remedy. If (i) a Reporting Event of Default occurs and the Company elects that the sole remedy with respect to such Reporting
Event of Default will be the Special Interest; and (ii) on the sixty first (61st) day immediately following, and including, the
date on which such Reporting Event of Default first occurred, such Reporting Event of Default has not been cured or validly waived
in accordance with Section 6.05, then this Note will become subject to acceleration under Section 6.02(a) on account
of such Reporting Event of Default. For the avoidance of doubt, Special Interest will cease to accrue from such sixty first (61st)
day, without limiting the generality of this Section 6.04 as it may apply to any subsequent Reporting Event of Default.


 


(c)          Company
Election Notice. To elect to pay the Special Interest as the sole remedy for a Reporting Event of Default, the Company must
deliver written notice of such election to the Holder prior to the date on which such Reporting Event of Default first occurs.
Any such notice must include a brief description of the report that the Company failed, or will fail, to file, a statement that
the Company is electing to pay the Special Interest and the date on which such Reporting Event of Default will occur. If a Reporting
Event of Default occurs and the Company fails to timely deliver such notice for such Reporting Event of Default or fails to pay
the Special Interest, this Note will be subject to acceleration under Section 6.02(a) on account of such Reporting Event
of Default.


 


(d)          Other
Events of Default. Notwithstanding anything to the contrary herein, if the Company elects to pay Special Interest with respect
to any Reporting Event of Default, the Company’s election will not affect the rights of the Holder with respect to any other
Event of Default, including with respect to any other Reporting Event of Default; provided, that, for the avoidance of doubt,
in no event will the Company be obligated to pay Special Interest at a rate greater than 0.50% per annum on the principal amount
of this Note.


 




    	 	- 21 -	 



     


    

 


 


Section 6.05         Waiver
of Past Defaults. If an Event of Default described in Sections 6.01(a)(i), 6.01(a)(ii), 6.01(a)(iv) or
6.01(a)(vi) (which, in the case of Section 6.01(a)(vi) only, relates to a covenant that cannot be amended without
the consent of each affected holder of a note in the Series) or a Default that would lead to such an Event of Default occurs and
is continuing, such Event of Default or Default may be waived only with the consent of each affected holder of a note in the Series.
Every other Event of Default or Default may be waived by the holders of a majority of the aggregate principal amount of the outstanding
Series (including consents obtained in connection with a repurchase of, or tender offer or exchange offer for, notes in the Series).
Whenever any Event of Default is so waived, it will cease to exist, and whenever any Default is so waived, it will be deemed cured
and any Event of Default arising therefrom will be deemed not to occur. However, no such waiver will extend to any subsequent or
other Default or Event of Default or impair any consequent right

CONVERSIONS


 


Section
8.01           Right To Convert.


 


(a)          In
General. Subject to, and upon compliance with, the provisions of this Article 8, at any time prior to the Close of Business
on the second (2nd) Business Day immediately preceding the Maturity Date, the Holder may, at its option, convert this Note (or
any portion thereof) into Conversion Consideration, as provided in this Article 8. This Note may not be converted after
the Close of Business on the second (2nd) Business Day immediately preceding the Maturity Date.


 


(b)          Closed
Periods. Notwithstanding anything to the contrary in this Note, if the Holder tenders a Repurchase Notice with respect to this
Note in accordance with Article 3, this Note may not be converted except to the extent (i) this Note is not subject to such
Repurchase Notice, (ii) such Repurchase Notice is withdrawn in accordance with Article 3 or (iii) the Company fails to pay
the Fundamental Change Repurchase Price for this Note in accordance with Section 3.05(b).

Section
8.02         Conversion Procedures.


 


(a)          General.
To exercise its conversion right with respect to this Note, the Holder must (i) complete and manually sign a conversion notice
in the form set forth in Exhibit A hereto, or a facsimile of such conversion notice (such notice, or such facsimile, the
“Conversion Notice”); (ii) deliver such signed and completed Conversion Notice, which shall be irrevocable,
and this Note to the Company; (iii) furnish any endorsements and transfer documents that the Company may require; and (iv) pay
any amounts due pursuant to Section 8.02(d) or 8.02(e). The first Business Day on which the Holder satisfies the
foregoing requirements with respect to this Note and on which conversion of this Note is not otherwise prohibited hereunder will
be the “Conversion Date” for this Note. If the Holder has delivered a Fundamental Change Repurchase Notice with
respect to this Note, the Holder may not surrender this Note for conversion until the Holder has withdrawn such Fundamental Change
Repurchase Notice in accordance with Section 3.04. The conversion of this Note will be deemed to occur at the Close of Business
on the Conversion Date for this Note, and this converted Note or portion thereof will cease to be outstanding upon conversion.


 


(b)          Holder
of Record. If the Holder surrenders the entire principal amount of this Note for conversion, the Holder will no longer be the
Holder of this Note as of the Close of Business on the Conversion Date for this Note. The person in whose name any shares of Common
Stock are issuable upon conversion of this Note will become the holder of record of such shares as of the Close of Business on
the Conversion Date for such conversion.


 


(c)          Conversions
in Part. If the Holder surrenders only a portion of the principal amount of this Note for conversion, promptly after the Conversion
Date for such portion, the Company will deliver to the Holder a new Note, having a principal amount equal to the aggregate principal
amount of the unconverted portion of the Note surrendered for conversion.


 


(d)          Reimbursement
of Interest upon Conversion. If the Holder converts this Note after the Close of Business on a Regular Record Date, but prior
to the Open of Business on the Interest Payment Date corresponding to such Regular Record Date, then (x) the Holder at the Close
of Business on such Regular Record Date shall be entitled, notwithstanding such conversion, to receive, on the date the Company
delivers (or is required to deliver) the Conversion Consideration due in respect of such conversion, the unpaid interest that would
have accrued on such Note to, but excluding, such Interest Payment Date (assuming, solely for these purposes, that such Note remained
outstanding through such Interest Payment Date); and (y) the Holder must, upon surrender of this Note for conversion, accompany
this Note with an amount of cash equal to the amount of such interest referred to in clause (x) above; provided, however,
that the Holder need not make such payment (A) for conversions following the Regular Record Date immediately preceding the Maturity
Date; (B) if the Company has specified a Fundamental Change Repurchase Date that is after such Regular Record Date and on or prior
to the Business Day immediately following such Interest Payment Date; or (C) to the extent of any overdue interest, if any overdue
interest exists at the time of conversion with respect to this Note. For the avoidance of doubt, the Holder at the Close of Business
on the Regular Record Date immediately preceding the Maturity Date will be entitled to receive interest that accrues (or would
have accrued) on this Note to, but excluding, the Maturity Date notwithstanding any conversion of this Note.


 




    	 	- 23 -	 



     


    

 


(e)         Taxes
and Duties. If the Holder converts this Note, the Company will pay any documentary, stamp or similar issue or transfer tax
due on the issue of any shares of the Common Stock upon the conversion; provided, however, that if any tax is due
because the Holder requested that shares of Common Stock be issued in a name other than its own, the Holder will pay such tax and
the Company, until having received a sum sufficient to pay such tax, may refuse to deliver any certificates representing the shares
of Common Stock being issued in a name other than that of the Holder.


 


(f)         Restrictions
on Conversion. Notwithstanding anything to the contrary in this Note, this Note will not be convertible by the Holder, and
the Company will not effect any conversion of this Note, in each case to the extent (and only to the extent) that such convertibility
or conversion would result in the Holder or any of its Affiliates beneficially owning in excess of 9.99% of the then-outstanding
shares of Common Stock. For these purposes, beneficial ownership and all determinations and calculations (including with respect
to calculations of percentage ownership) will be determined in accordance with Section 13(d) of the Exchange Act and the rules
and regulations promulgated thereunder. For the avoidance of doubt, if the convertibility of this Note is restricted pursuant to
this Section 8.02(f), this Note will continue to be outstanding, and its convertibility will be reinstated if and when the
convertibility and conversion will not violate the limitations set forth in this Section 8.02(f).


 


Section
8.03         Settlement Upon Conversion.


 


(a)          Conversion
Obligation.


 


(i)          Conversion
Consideration. Subject to the terms hereof, upon conversion of this Note, the consideration (the “Conversion Consideration”)
due in respect of each $1,000 principal amount of this Note to be converted will consist of (I) a whole number of shares of Common
Stock equal to the Conversion Rate in effect on the Conversion Date for such conversion (which, if not a whole number, will be
rounded down to the nearest whole number); (II) in the case of a principal amount or portion of a principal amount that is not
a multiple of $1,000, an equivalent pro rata number of shares and (III) if such Conversion Rate is not a whole number, cash in
lieu of the related fractional share in an amount equal to the product of (x) the Last Reported Sale Price per share of Common
Stock on such Conversion Date (or, if such Conversion Date is not a Trading Day, the immediately preceding Trading Day) and (y)
the fractional portion of such Conversion Rate.


 


(ii)         Delivery
of Conversion Consideration. Except as set forth in Section 8.05, the Company will pay or deliver, as the case
may be, the Conversion Consideration due upon the conversion of this Note to the Holder on the third (3rd) Business Day immediately
following the Conversion Date for such conversion.


 


(b)          Settlement
of Accrued Interest and Deemed Payment of Principal. If the Holder converts this Note, the Company will not adjust the Conversion
Rate to account for any accrued and unpaid interest on this Note, and, except as provided in Section 8.02(d), the Company’s
delivery of the Conversion Consideration due upon such conversion will be deemed to satisfy and discharge in full the Company’s
obligation to pay the principal of this Note and accrued and unpaid interest, if any, on, this Note to, but excluding the Conversion
Date. As a result, except as provided in Section 8.02(d), any accrued and unpaid interest with respect to this Note, in
the event that it is converted, will be deemed to be paid in full rather than cancelled, extinguished or forfeited.


 




    	 	- 24 -	 



     


    

 


Section
8.04         Common Stock Issued Upon Conversion.


 


(a)          The
Company will reserve out of its authorized but unissued shares of Common Stock, and keep available to satisfy conversion of this
Note, a number of shares of Common Stock sufficient to permit the conversion this Note, after giving effect to the largest number
of Additional Shares that may from time to time be added to the Conversion Rate as provided in Section 8.07.


 


(b)          Any
shares of Common Stock delivered upon the conversion of this Note will be newly issued shares or treasury shares, duly and validly
issued, fully paid, nonassessable, free from preemptive rights and free of any lien or adverse claim (except to the extent of any
lien or adverse claim created by the action or inaction of the Holder or other Person to whom such shares of Common Stock will
be delivered). In addition, the Company will endeavor to comply promptly with all federal and state securities laws regulating
the offer and delivery of any shares of Common Stock issuable upon conversion of this Note. The Company will also use its best
efforts to cause any shares of Common Stock issuable upon conversion of this Note to be listed on whatever stock exchange(s) the
Common Stock is listed on the date the Holder becomes a record holder of such Common Stock.


 


Section 8.05         Adjustment
of Conversion Rate. The Company will adjust the Conversion Rate from time to time as described in this Section 8.05,
except that the Company will not make an adjustment to the Conversion Rate if the Holder participates (other than in a share split
or share combination), at the same time and upon the same terms as holders of the Common Stock, and solely as a result of holding
this Note, in the relevant transaction described in this Section 8.05 without having to convert its Note and as if it held
a number of shares of the Common Stock equal to the product of (i) the Conversion Rate in effect on the applicable record date,
Effective Date or expiration date; and (ii) the aggregate principal amount of this Note (expressed in thousands) on such date.


 


(a)          Stock
Dividends and Share Splits. If the Company exclusively issues to all or substantially all holders of the Common Stock shares
of Common Stock as a dividend or distribution on shares of the outstanding Common Stock, or if the Company effects a share split
of the Common Stock or a share combination of the Common Stock (excluding an issuance solely pursuant to a Common Stock Change
Event, as to which the provisions set forth in Section 8.08(a) will apply), the Conversion Rate will be adjusted based on
the following formula:


 


 


 


where:


 


		CR0	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date of such dividend or distribution,
or immediately prior to the Open of Business on the Effective Date of such share split or share combination, as applicable;



 




    	 	- 25 -	 



     


    

 


		CR1	=	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date or Effective Date, as applicable;



 


		OS0	=	the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date or Effective
Date, as applicable; and



 


		OS1	=	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or
share combination, as applicable.



 


Such adjustment shall become effective
immediately after the Open of Business on such Ex-Dividend Date or Effective Date, as applicable. If any dividend, distribution,
share split or share combination of the type described in this Section 8.05(a) is declared, but not so paid or made, the
Conversion Rate will be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend
or distribution or to effect such share split or share combination, to the Conversion Rate that would then be in effect if such
dividend, distribution, share split or share combination had not been declared or announced.


 


(b)          Rights,
Options and Warrants. If the Company issues, to all or substantially all holders of its outstanding Common Stock, rights, options
or warrants entitling such holders, for a period of not more than sixty (60) calendar days after the record date of such issuance,
to subscribe for, or purchase, shares of Common Stock, at a price per share less than the average of the Last Reported Sale Prices
per share of the Common Stock for the ten (10) consecutive Trading Day period ending on, and including, the Trading Day immediately
preceding the date of announcement of such issuance, then, subject to the provisions described below with respect to rights issued
pursuant to a stockholder rights plan, the Conversion Rate will be increased based on the following formula:


 


 


 


where:


 


		CR0	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such issuance;



 


		CR1	=	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;



 


		OS	=	the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date;



 


		X	=	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and



 


	 	Y	=	the number of shares of Common Stock equal to the quotient of (i) the aggregate price payable to exercise such rights, options
or warrants, over (ii) the average of the Last Reported Sale Prices per share of the Common Stock over the ten (10) consecutive
Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of
such rights, options or warrants.



 




    	 	- 26 -	 



     


    

 


Such adjustment shall become effective
immediately after the Open of Business on such Ex-Dividend Date. To the extent that shares of Common Stock are not delivered after
the expiration of such rights, options or warrants, including because the issued rights, options or warrants were not exercised,
the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the increase with respect to the
issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually
delivered. If such rights, options or warrants are not so issued, the Conversion Rate will be readjusted to the Conversion Rate
that would then be in effect if the Ex-Dividend Date for such issuance had not occurred.


 


For purposes of this Section 8.05(b),
in determining whether any rights, options or warrants entitle holders of the Common Stock to subscribe for, or purchase, shares
of Common Stock at a price per share less than the average of the Last Reported Sale Prices per share of Common Stock for the ten
(10) consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement for
an issuance, and in determining the aggregate price payable to exercise such rights, options or warrants, there will be taken into
account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise thereof,
the value of such consideration, if other than cash, to be determined by the Board of Directors.


 


(c)          Spin-Offs
and Other Distributed Property.


 


(i)          If
the Company distributes shares of its Capital Stock, evidences of its indebtedness or other assets or property of the Company,
or rights, options or warrants to acquire Capital Stock of the Company or other securities, to all or substantially all holders
of the Common Stock, excluding:


 


(A)         dividends,
distributions, rights, options or warrants for which an adjustment was effected pursuant to Section 8.05(a) or 8.05(b),
as applicable;


 


(B)         dividends
or distributions paid exclusively in cash for which an adjustment was effected pursuant to Section 8.05(d);


 


(C)         Spin-Offs
for which the provisions described in Section 8.05(c)(ii) will apply; and


 


(D)         an
issuance solely pursuant to a Common Stock Change Event, as to which the provisions set forth in Section 8.08(a) will apply,


 




    	 	- 27 -	 



     


    

 


then the Conversion Rate will
be increased based on the following formula:


 


 


 


where:


 


		CR0	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;



 


		CR1	=	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;



 


		SP0	=	the average of the Last Reported Sale Prices per share of the Common Stock over the ten (10) consecutive Trading Day period ending
on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and



 


		FMV	=	the fair market value (as determined by the Board of Directors) of the shares of Capital Stock, evidences of indebtedness, assets,
property, rights, options or warrants distributed with respect to each outstanding share of Common Stock on the Ex-Dividend Date
for such distribution.



 


Such adjustment shall become
effective immediately after the Open of Business on such Ex-Dividend Date. Notwithstanding the foregoing, if “FMV”
(as defined above) is equal to or greater than the “SP0” (as defined above), in lieu of the foregoing increase,
the Holder will receive, for each $1,000 principal amount of this Note outstanding on the record date for the distribution, at
the same time and upon the same terms as holders of the Common Stock, the amount and kind of shares of Capital Stock, evidences
of indebtedness, assets or property, rights, options or warrants or other securities that the Holder would have received if the
Holder had owned a number of shares of Common Stock equal to the Conversion Rate in effect on the record date for such distribution
(or in the case of a principal amount or portion of a principal amount that is not a multiple of $1,000, an equivalent pro rata
amount).


 


If any distribution of the type
described in this Section 8.05(c)(i) is not so paid or made, or if any rights, options or warrants are not exercised before
their expiration date, the Conversion Rate will be readjusted to be the Conversion Rate that would then be in effect if such distribution
had not been declared.


 


(ii)         With
respect to an adjustment pursuant to this Section 8.05(c) where there has been a payment of a dividend or other distribution
on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to an Affiliate,
a Subsidiary or other business unit of the Company, and such Capital Stock or similar equity interest is listed or quoted (or will
be listed or quoted upon the consummation of the transaction) on a national securities exchange or a reasonably comparable non-U.S.
equivalent (a “Spin-Off”), but excluding an issuance solely pursuant to a Common Stock Change Event as to which
the provisions described in Section 8.08(a) apply, the Conversion Rate will be increased based on the following formula:


 




    	 	- 28 -	 



     


    

 


 


 


where:


 


		CR0	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such Spin-Off;



 


		CR1	=	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;



 


		FMV0	=	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common
Stock applicable to one share of Common Stock (determined for purposes of the definition of Last Reported Sale Price as if such
Capital Stock or similar equity interest were the Common Stock) over the first ten (10) consecutive Trading Day period after,
and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); and



 


		MP0	=	the average of the Last Reported Sale Prices per share of the Common Stock over the Valuation Period.



 


Such adjustment shall become
effective immediately after the Open of Business on such Ex-Dividend Date. The adjustment to the Conversion Rate under this Section
8.05(c)(ii) will be calculated as of the Close of Business on the last Trading Day of the Valuation Period but will be given
effect as of immediately after the Open of Business on the Ex-Dividend Date of the Spin-Off. Notwithstanding anything to the contrary
herein or in this Note, if necessary, the Company shall delay the settlement of any conversion of this Note where the Conversion
Date occurs during the Valuation Period until the third (3rd) Business Day after the last day of the Valuation Period. If any distribution
of the type described in this Section 8.05(c)(ii) is declared but not so made, the Conversion Rate shall be immediately
readjusted, effective as of the date the Board of Directors determines not to make such distribution, to the Conversion Rate that
would then be in effect if such distribution had not been declared.


 


(d)          Cash
Dividends or Distributions. If any cash dividend or distribution (other than a distribution as to which an adjustment to the
Conversion Rate was effected pursuant to Section 8.05(e)) is made to all or substantially all holders of the Common Stock,
the Conversion Rate will be increased based on the following formula:


 


 


 




    	 	- 29 -	 



     


    

 


where:


 


		CR0	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such dividend or distribution;



 


		CR1	=	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution;



 


		SP0	=	the Last Reported Sale Price per share of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such
dividend or distribution; and



 


		C	=	the amount in cash per share the Company distributes to holders of Common Stock.



 


Such adjustment shall become effective
immediately after the Open of Business on such Ex-Dividend Date. Notwithstanding the foregoing, if “C” (as defined
above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, the Holder
will receive, for each $1,000 principal amount of this Note outstanding on the record date for such cash dividend or distribution,
at the same time and upon the same terms as holders of the Common Stock, the amount of cash that the Holder would have received
if the Holder had owned a number of shares of Common Stock equal to the Conversion Rate in effect on such record date (or in the
case of a principal amount or portion of a principal amount that is not a multiple of $1,000, an equivalent pro rata number of
shares). If any dividend or distribution of the type described in this Section 10.05(d) is declared but not so paid
or made, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect if such dividend or distribution
had not been declared.


 


(e)          Tender
Offers or Exchange Offers. If the Company or any Subsidiary makes a payment in respect of a tender offer or exchange offer
for the Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of Common
Stock exceeds the Last Reported Sale Price per share of the Common Stock on the Trading Day next succeeding the last date (the
“Expiration Date”) on which tenders or exchanges may be made pursuant to such tender offer or exchange offer
(as it may be amended), the Conversion Rate will be increased based on the following formula:


 





 


where:


 


		CR0	=	the Conversion Rate in effect immediately prior to the Expiration Time (as defined below);



 


		CR1	=	the Conversion Rate in effect immediately after the Expiration Time;



 




    	 	- 30 -	 



     


    

 


		AC	=	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares
purchased in such tender or exchange offer;



 


		OS0	=	the number of shares of Common Stock outstanding immediately prior to the time (the “Expiration Time”)
on the date such tender or exchange offer expires (prior to giving effect to the purchase of all shares accepted for purchase
or exchange in such tender or exchange offer);



 


		OS1	=	the number of shares of Common Stock outstanding immediately after the Expiration Time (after giving effect to the purchase of
all shares accepted for purchase or exchange in such tender or exchange offer); and



 


		SP1	=	the average of the Last Reported Sale Prices per share of the Common Stock over the ten (10) consecutive Trading Day period (the
“Averaging Period”) commencing on the Trading Day next succeeding the Expiration Date.



 


The adjustment to the Conversion Rate pursuant
to this Section 8.05(e) will be calculated as of the Close of Business on the last Trading Day of the Averaging Period but
will be given effect as of immediately after the Expiration Time. Notwithstanding anything to the contrary herein, if necessary,
the Company shall delay the settlement of any conversion of this Note where the Conversion Date occurs during the Averaging Period
until the third (3rd) Business Day after the last day of the Averaging Period.


 


(f)          Successive
Adjustments. After an adjustment to the Conversion Rate under this Article 8, any subsequent event requiring an adjustment
under this Article 8 will cause an adjustment to the Conversion Rate as so adjusted, without duplication.


 


(g)          Limitations
Imposed by Stock Market Listing Standards. The Company will not enter into any transaction, or take any other voluntary action,
that would result in an adjustment to the Conversion Rate that would violate the listing standards of any securities exchange on
which any securities of the Company may be then listed, without complying, if applicable, with the requirements of such listing
standards.


 


(h)          Special
Settlement Provisions. Notwithstanding anything to the contrary herein, if:


 


(i)          this
Note is to be converted and, as of the Conversion Date for such conversion, any transaction or other event that requires an adjustment
to the Conversion Rate pursuant to Sections 8.05(a) through (e) has occurred but has not yet resulted in an adjustment
to the Conversion Rate;


 


(ii)         the
consideration due upon such conversion consists of any shares of Common Stock; and


 


(iii)        such
shares of Common Stock are not entitled to participate in such transaction or event because they were not held on the related record
date or otherwise, then, solely for purpose of such conversion, the Company shall, without duplication, give effect to such adjustment
on such Conversion Date.


 




    	 	- 31 -	 



     


    

 


In addition, notwithstanding anything to
the contrary herein, if:


 


(i)          a
Conversion Rate adjustment for any transaction or other event becomes effective on any Ex-Dividend Date pursuant to Sections
8.05(a) through (e);


 


(ii)         this
Note is to be converted;


 


(iii)        the
Conversion Date for such conversion occurs on or after such Ex-Dividend Date and on or before the related record date;


 


(iv)        the
consideration due upon such conversion includes any whole shares of Common Stock; and


 


(v)         the
Holder would be treated, on such record date, as the record holder of such shares of Common Stock based on a Conversion Rate that
is adjusted for such event,


 


then such Conversion Rate adjustment shall
not be given effect for such conversion. Instead, the Holder will be treated as if the Holder were, as of such record date, the
record holder of such shares of Common Stock on an unadjusted basis and will participate in such transaction or event.


 


(i)          Shareholder
Rights Plans. If the Company has a rights plan in effect when the Holder converts this Note, the Company will deliver to the
Holder, to the extent the Holder receives any shares of Common Stock upon such conversion of this Note, any rights that, under
the rights plan, would be applicable to a share of Common Stock, unless prior to the Conversion Date for this Note, the rights
have separated from the Common Stock, in which case, and only in such case, the Conversion Rate will be adjusted pursuant to Section
8.05(c)(i) as if, at the time of such separation, the Company had distributed to all holders of the Common Stock shares of
its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire
its Capital Stock or other securities, subject to readjustment in the event of the expiration, termination or redemption of such
rights.


 


(j)          Other
Adjustments. Whenever any provision of this Note requires the calculation of the Last Reported Sale Price or a function thereof
over a period of multiple days (including the Stock Price for purposes of a Make-Whole Fundamental Change), the Company will make
appropriate adjustments to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an
adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date or expiration date of the event occurs, at any time
during such period.


 


(k)          Restrictions
on Adjustments. Except as a result of a reverse share split or a share combination subject to Section 8.05(a), and except
for readjustments pursuant to the last paragraph of Section 8.05(a), readjustments pursuant to the penultimate paragraph
of Section 8.05(b), readjustments pursuant to the last paragraph of Section 8.05(c)(i), readjustments pursuant to
the penultimate paragraph of Section 8.05(c)(ii) and readjustments pursuant to Section 8.05(d), in no event will
the Conversion Rate be adjusted downward pursuant to Section 8.05(a), (b), (c), (d) or (e).
In addition, notwithstanding anything to the contrary elsewhere in this Note, the Conversion Rate will not be adjusted:


 




    	 	- 32 -	 



     


    

 


(i)          upon
the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or
interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock
under any plan;


 


(ii)         upon
the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee,
director or consultant benefit plan or program of, or assumed by, the Company or any of its Subsidiaries;


 


(iii)        upon
the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security

(ii)         Notices.
Whenever the Company adjusts (or is required to adjust) the Conversion Rate pursuant to this Section 8.05, the Company will
promptly deliver to the Holder a written notice, which notice will include (i) a brief description of the event requiring adjustment
to the Conversion Rate pursuant to this Section 8.05; (ii) the effective time of such adjustment; (iii) the Conversion Rate
in effect immediately after such adjustment is made; and (iv) a schedule explaining, in reasonable detail, how the Company calculated
such adjustment.


 


(iii)        All
calculations and other determinations in respect of the Conversion Rate will be made by the Company to the nearest 1/10,000th of
a share, with 5/100,000ths rounded upward.


 


Section
8.06         Voluntary Adjustments.


 


(a)          Best
Interest Increases. The Company may, from time to time, to the extent permitted by law and the applicable rules of any exchange
on which the Common Stock is listed, increase the Conversion Rate by any amount if (i) the Board of Directors determines that such
increase is in the best interest of the Company; (ii) such increase is in effect for a period of at least twenty (20) Business
Days; and (iii) during such period, such increase is irrevocable.


 


(b)          Tax-Related
Increases. To the extent permitted by law and the applicable rules of any exchange on which the Common Stock is listed, the
Company may (but is not required to) increase the Conversion Rate if the Board of Directors determines that such increase is advisable
to avoid, or diminish, any income tax imposed on holders of the Common Stock or rights to purchase the Common Stock as a result
of any dividend or distribution of shares (or rights to acquire shares) or similar event treated as such for U.S. federal income
tax purposes.


 


(c)          Notices.
Whenever the Board of Directors determines that the Company will increase the Conversion Rate pursuant to this Section 8.06,
the Company will deliver to the Holder notice of such increase at least fifteen (15) Business Days before such increase will take
effect, which notice will state the increase to be made and the period during which such increase will be in effect.


 


Section
8.07         Adjustments Upon Certain Fundamental Changes.


 


(a)          General.
If a Fundamental Change (determined after giving effect to the penultimate paragraph of the definition thereof, but without regard
to the exclusion in clause (b)(ii) of the definition thereof) occurs (a “Make-Whole Fundamental Change”), and
the Holder converts this Note “in connection with” such Make-Whole Fundamental Change, the Company will, in the circumstances
described in this Section 8.07, increase the Conversion Rate for this Note by the number of additional shares of Common
Stock (the “Additional Shares”) set forth in this Section 8.07. For purposes of this Section 8.07,
a conversion of this Note will be deemed to be “in connection with” a Make-Whole Fundamental Change if the applicable
Conversion Date occurs during the period from, and including, the effective date of the Make-Whole Fundamental Change up to, and
including, the Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole
Fundamental Change that would have been a Fundamental Change but for the exclusion in clause (b)(ii) of the definition thereof,
the thirty fifth (35th) Trading Day immediately following the effective date of such Make-Whole Fundamental Change). As promptly
as practicable, but in no event later than the Business Day after the effective date of a Make-Whole Fundamental Change, the Company
will notify the Holder of such effective date.


 




    	 	- 34 -	 



     


    

 


(b)          Determination
of Additional Shares. The number of Additional Shares, if any, by which the Conversion Rate will be increased if the Holder
converts this Note in connection with a Make-Whole Fundamental Change will be determined by reference to the table below, and will
be based on the Make-Whole Fundamental Change Effective Date and the Stock Price for such Make-Whole Fundamental Change. For any
Make-Whole Fundamental Change, the “Make-Whole Fundamental Change Effective Date” will mean the date on which
such Make-Whole Fundamental Change occurs or becomes effective.


 


(c)          Adjustment
of Stock Prices and Additional Shares. The Stock Prices set forth in the first row (i.e., the column headers) of the
table below will be adjusted on each date on which the Conversion Rate must be adjusted pursuant to Section 8.05. The adjusted
Stock Prices will equal the Stock Prices in effect immediately prior to such adjustment, multiplied by a fraction, (i) the numerator
of which is the Conversion Rate in effect immediately prior to the adjustment giving rise to the share price adjustment; and (ii)
the denominator of which is the Conversion Rate in effect immediately after the adjustment. The numbers of Additional Shares set
forth in the table below will be adjusted in the same manner, at the same time and for the same events for which the Conversion
Rate is adjusted pursuant to Section 8.05.


 


(d)          Additional
Shares Table. The following table sets forth hypothetical Make-Whole Fundamental Change Effective Dates, Stock Prices and the
number of Additional Shares by which the Conversion Rate will be increased per $1,000 principal amount of this Note for the Holder
that converts this Note in connection with a Make-Whole Fundamental Change having such Make-Whole Fundamental Change Effective
Date and Stock Price. In the case of a principal amount or portion of a principal amount that is not a multiple of $1,000, the
Conversion Rate will be increased by an equivalent pro rata number of shares.

(e)          Use
of Additional Shares Table. If the Stock Price and/or Make-Whole Fundamental Change Effective Date for a Make-Whole Fundamental
Change are not set forth in the table above, then:


 


(A)         if
the Stock Price is between two Stock Prices in the table or the Make-Whole Fundamental Change Effective Date is between two Make-Whole
Fundamental Change Effective Dates in the table, the number of Additional Shares by which the Conversion Rate will be increased
for the Holder that converts this Note in connection with such Make-Whole Fundamental Change will be determined by a straight-line
interpolation between the numbers of Additional Shares set forth for the higher and lower Stock Prices listed in the table and
the earlier and later Make-Whole Fundamental Change Effective Dates listed in the table, as applicable, based on a 365- or 366-day
year, as applicable;


 




    	 	- 35 -	 



     


    

 


(B)         if
the Stock Price is greater than $8.00, subject to adjustment in the same manner as the Stock Prices set forth in the column headings
of the table, no Additional Shares will be added to the Conversion Rate; and


 


(C)         if
the Stock Price is less than $0.60 per share, subject to adjustment in the same manner as the Stock Prices set forth in the column
headings of the table, no Additional Shares will be added to the Conversion Rate.


 


Notwithstanding the foregoing, in no event
will the Conversion Rate be increased as a result of this Section 8.07 to exceed 1,673.1918 shares of Common Stock per $1,000
principal amount of this Note, subject to adjustment in the same manner, at the same time and for the same events for which the
Conversion Rate must be adjusted as set forth in Section 8.05.


 


(f)          Settlement
or Conversion. If the Holder converts this Note in connection with a Make-Whole Fundamental Change, the Company will settle
such conversion by delivering Conversion Consideration in accordance with Section 8.03; provided, however,
that notwithstanding anything to the contrary in Section 8.03, if the Holder converts this Note in connection with a Make-Whole
Fundamental Change described in clause (b)(ii) of the definition of Fundamental Change in which the holders of the Common Stock
receive only cash in consideration for their shares of Common Stock, the Company will settle such conversion by delivering to the
Holder, on the third (3rd) Business Day immediately following the Conversion Date for this Note, an amount of cash, for each $1,000
principal amount of this Note so converted, equal to the product of (i) the Conversion Rate on the Conversion Date applicable to
this Note (including any Additional Shares added to such Conversion Rate pursuant to this Section 8.07) and (ii) the Stock
Price for such Make-Whole Fundamental Change, or in the case of a principal amount or portion of a principal amount that is not
a multiple of $1,000, an equivalent pro rata amount.


 


Section
8.08         Effect of Recapitalization, Reclassification, Consolidation, Merger
or Sale.


 


(a)          General.
If any of the following events occur:


 


(1)           any
recapitalization, reclassification or change of Common Stock (other than (x) a change only in par value, from par value to no par
value or no par value to par value; or (y) changes resulting from a stock split or combination not involving the issuance of any
other class or series of securities);


 


(2)           any
consolidation, merger, combination or similar transaction involving the Company;


 


(3)           any
sale, lease or other transfer to a third party of all or substantially all of the consolidated assets of the Company and its Subsidiaries
substantially as an entirety; or


 




    	 	- 36 -	 



     


    

 


(4)         any
statutory share exchange,


 


and, in each case, as a result of which
the Common Stock would be converted into, or exchanged for, or represent solely the right to receive, stock (including one or more
series of the Common Stock), other securities, other property or assets (including cash or any combination thereof) (any such event,
a “Common Stock Change Event” and such stock, other securities, other property or assets, the “Reference
Property”, and the amount and kind of Reference Property that a holder of one share of Common Stock would be entitled
to receive on account of such Common Stock Change Event, a “Reference Property Unit”), then, notwithstanding
anything to the contrary, at the effective time of such transaction, the consideration due upon a conversion of this Note will
be determined in the same manner as if each reference to any number of shares of Common Stock in this Article 8 were instead
a reference to the same number of Reference Property Units. For these purposes, the Last Reported Sale Price of any Reference Property
Unit or portion thereof that does not consist of a class of securities will be the fair value of such Reference Property Unit or
portion thereof, as applicable, determined in good faith by the Company (or, in the case of cash denominated in U.S. dollars, the
face amount thereof).


 


If the Reference Property consists of more
than a single type of consideration (determined based in part upon any form of stockholder election), then the composition of the
Reference Property Unit shall be deemed to be (a) the weighted average, per share of Common Stock, of the types and amounts of
consideration received by the holders of Common Stock that affirmatively make such an election; or (b) if no holders of the Common
Stock affirmatively make such an election, the types and amounts of consideration actually received, per share of Common Stock,
by the holders of the Common Stock. The Company shall notify the Holder of such weighted average (if applicable) as soon as practicable
after such determination is made.


 


None of the foregoing provisions will affect
the right of the Holder to convert this Note as set forth in Section 8.01 and 8.02 prior to the effective date of
such Common Stock Change Event.


 


(b)          Notices.


 


(i)          As
soon as practicable upon learning of the anticipated or actual effective date of any Common Stock Change Event, the Company will
deliver written notice of such Common Stock Change Event to the Holder. Such Notice will include:


 


(A)         a
brief description of such Common Stock Change Event;


 


(B)         the
Conversion Rate in effect on the date the Company delivers such notice;


 


(C)         the
anticipated effective date for the Common Stock Change Event;


 


(D)         that,
on and after the effective date for the Common Stock Change Event, this Note will be convertible into Reference Property Units
and cash in lieu of fractional Reference Property Units; and


 




    	 	- 37 -	 



     


    

 


(E)         the
composition of the Reference Property Unit for such Common Stock Change Event.


 


(c)          Successive
Common Stock Change Events. If more than one Common Stock Change Event occurs, this Section 8.08 will apply successively
to each Common Stock Change Event.


 


(d)          Compliance
Covenant. The Company will not become a party to any Common Stock Change Event unless its terms are consistent with this Section
8.08.

Section 10.09         Legal
Holidays. If the Maturity Date or any Interest Payment Date or Fundamental Change Repurchase Date is not a Business Day (which,
solely for the purposes of any payment required to be made on this Note on any such date will be deemed not to include any day
on which the office where the place of payment is authorized or required by law to close), then any action to be taken on such
date need not be taken on such date, but may be taken on the immediately following Business Day, and no interest on such payment
will accrue as a result of such delay.

without the consent of each affected holder, no amendment to the notes of the Series, or waiver of any provision of the notes of
the Series, may:


 


(a)          reduce
the principal amount of, or change the Maturity Date of, any note of the Series;


 


(b)          reduce

the ranking of the notes of the Series;


 


(h)          make
any change to any amendment, modification or waiver of a provision of a note of the Series that requires the consent of each affected
holder of notes of the Series; or


 


(i)           reduce
the percentage of the aggregate principal amount of then outstanding notes of the Series whose holders must consent to an amendment
or modification of any note of the Series or a waiver of a past Default.


 


It will not be necessary for the consent
of the holders under this Section 10.13 to approve the particular form of any proposed amendment or modification, but it
will be sufficient if such consent approves the substance of such proposed amendment or modification.
