CONVERSION OF NOTES. This Note shall be convertible into validly issued, fully paid and non-assessable shares of
Common Stock (as defined below), on the terms and conditions set forth in this Section 3.


 


(a)            
Conversion Right. Subject to the provisions of Section 3(d), at any time or times on or after the Issuance Date,
the Holder shall be entitled to convert any portion of the outstanding and unpaid Conversion Amount (as defined below) into validly
issued, fully paid and non-assessable shares of Common Stock in accordance with Section 3(c), at the Conversion Rate (as defined
below). The Company shall not issue any fraction of a share of Common Stock upon any conversion. If the issuance would result in
the issuance of a fraction of a share of Common Stock, the Company shall round such fraction of a share of Common Stock up to the
nearest whole share. The Company shall pay any and all transfer, stamp, issuance and similar taxes that may be payable with respect
to the issuance and delivery of Common Stock upon conversion of any Conversion Amount.

(c)            
Mechanics of Conversion.


 


(i)                
Optional Conversion. To convert any Conversion Amount into shares of Common Stock on any date (a “Conversion
Date”), the Holder shall (A) deliver (whether via facsimile or otherwise), for receipt on or prior to 11:59 p.m., New
York time, on such date, a copy of an executed notice of conversion in the form attached hereto as Exhibit I (the “Conversion
Notice”) to the Company and the Trustee and (B) if required by Section 3(c)(iii), surrender this Note to a nationally
recognized overnight delivery service for delivery to the Company (or an indemnification undertaking with respect to this Note
in the case of its loss, theft or destruction as contemplated by Section 17(b)). On or before the first (1st) Trading
Day following the date of receipt of a Conversion Notice, the Company shall transmit by facsimile an acknowledgment of confirmation,
in the form attached hereto as Exhibit II, of receipt of such Conversion Notice to the Holder, the Trustee and the Company’s
transfer agent (the “Transfer Agent”). On or before the third (3rd) Trading Day following the date
of receipt of a Conversion Notice, the Company shall (1) provided that the Transfer Agent is participating in The Depository Trust
Company’s (“DTC”) Fast Automated Securities Transfer Program, credit such aggregate number of shares of
Common Stock to which the Holder shall be entitled to the Holder’s or its designee’s balance account with DTC through
its Deposit/Withdrawal at Custodian system or (2) if the Transfer Agent is not participating in the DTC Fast Automated Securities
Transfer Program, issue and deliver (via reputable overnight courier) to the address as specified in the Conversion Notice, a certificate,
registered in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder shall be entitled.
If this Note is physically surrendered for conversion as required by Section 3(c)(iii) and the outstanding Principal of this Note
is greater than the Principal portion of the Conversion Amount being converted, then the Company shall as soon as practicable and
in no event later than three (3) Trading Days after receipt of this Note and at its own expense, issue and, following authentication
of such new Note, deliver to the Holder (or its designee) a new Note (in accordance with Section 17(d)) representing the outstanding
Principal not converted. The Person or Persons entitled to receive the shares of Common Stock issuable upon a conversion of this
Note shall be treated for all purposes as the record holder or holders of such shares of Common Stock on the Conversion Date. In
the event of a partial conversion of this Note pursuant hereto, the Principal amount converted shall be deducted from the Installment
Amount(s) relating to the Installment Date(s) as set forth in the applicable Conversion Notice.


 






    	3



    	 



    

 


(ii)              
Company’s Failure to Timely Convert. If the Company shall fail, for any reason or for no reason, to issue to
the Holder within three (3) Trading Days after the Company’s receipt of a Conversion Notice (whether via facsimile or otherwise)
(the “Share Delivery Deadline”), a certificate for the number of shares of Common Stock to which the Holder
is entitled and register such shares of Common Stock on the Company’s share register or to credit the Holder’s or its
designee’s balance account with DTC for such number of shares of Common Stock to which the Holder is entitled upon the Holder’s
conversion of any Conversion Amount (as the case may be) (a “Conversion Failure”) and if on or after such Share
Delivery Deadline the Holder (or any other Person in respect, or on behalf, of the Holder) purchases (in an open market transaction
or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of all or any portion of the number of
shares of Common Stock, or a sale of a number of shares of Common Stock equal to all or any portion of the number of shares of
Common Stock, issuable upon such conversion that the Holder so anticipated receiving from the Company, then, in addition to all
other remedies available to the Holder, the Company shall, within three (3) Business Days after receipt of the Holder’s written
request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total
purchase price (including brokerage commissions and other out-of-pocket expenses, if any) for the shares of Common Stock so purchased
(including, without limitation, by any other Person in respect, or on behalf, of the Holder) (the “Buy-In Price”),
at which point the Company’s obligation to so issue and deliver such certificate or credit the Holder’s balance account
with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s conversion hereunder
(as the case may be) (and to issue such shares of Common Stock) shall terminate, or (ii) promptly honor its obligation to so issue
and deliver to the Holder a certificate or certificates representing such shares of Common Stock or credit the Holder’s balance
account with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s conversion hereunder
(as the case may be) and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product
of (A) such number of shares of Common Stock multiplied by (B) the lowest Closing Sale Price of the Common Stock on any Trading
Day during the period commencing on the date of the applicable Conversion Notice and ending on the date of such issuance and payment
under this clause (ii).


 


(iii)            
Registration; Book-Entry. The Trustee shall maintain a register (the “Register”) for the recordation
of the names and addresses of the holders of each Note and the principal amount of the Notes held by such holders (the “Registered
Notes”) as provided in Section 3.5 of the Indenture. No later than the first (1st) Trading Day after the completion
of any conversion or redemption of this Note, the Company shall deliver written confirmation to the Trustee that such conversion
or redemption, as applicable, has been completed in full, which confirmation shall set forth the aggregate Principal of this Note
then converted or redeemed, as applicable, and the remaining aggregate principal of this Note then outstanding. The entries in
the Register shall be conclusive and binding for all purposes absent manifest error. The Company and the holders of the Notes shall
treat each Person whose name is recorded in the Register as the owner of a Note for all purposes (including, without limitation,
the right to receive payments of Principal and Interest hereunder) notwithstanding notice to the contrary. A Registered Note may
be assigned, transferred or sold in whole or in part only by registration of such assignment or sale on the Register. Notwithstanding
anything to the contrary set forth in this Section 3 or in the Indenture or in the Series [A][B] Supplemental Indenture, following
conversion of any portion of this Note in accordance with the terms hereof, the Holder shall not be required to physically surrender
this Note to the Company unless (A) the full Conversion Amount represented by this Note is being converted (in which event this
Note shall be delivered to the Company following conversion thereof as contemplated by Section 3(c)(i)) or (B) the Holder has provided
the Company with prior written notice (which notice may be included in a Conversion Notice) requesting reissuance of this Note
upon physical surrender of this Note. The Holder, the Trustee and the Company shall maintain records showing the Principal, Interest
and Late Charges, if any, converted and/or paid (as the case may be) and the dates of such conversions and/or payments (as the
case may be) or shall use such other method, reasonably satisfactory to the Holder and the Company, so as not to require physical
surrender of this Note upon conversion.

(iv)            
Pro Rata Conversion; Disputes. In the event that the Company receives a Conversion Notice from more than one holder
of Notes for the same Conversion Date and the Company can convert some, but not all, of such portions of the Notes submitted for
conversion, the Company, subject to Section 3(d), shall convert from each holder of Notes electing to have Notes converted on such
date a pro rata amount of such holder’s portion of its Notes submitted for conversion based on the principal amount of Notes
submitted for conversion on such date by such holder relative to the aggregate principal amount of all Notes submitted for conversion
on such date. In the event of a dispute as to the number of shares of Common Stock issuable to the Holder in connection with a
conversion of this Note, the Company shall issue to the Holder the number of shares of Common Stock not in dispute and resolve
such dispute in accordance with Section 22.


 


(d)            Limitations on Conversions.


 


(i)                
Beneficial Ownership. Notwithstanding anything to the contrary contained in this Note, this Note shall not be convertible
by the Holder hereof, and the Company shall not effect any conversion of this Note or otherwise issue any shares of Common Stock
pursuant hereto, to the extent (but only to the extent) that after giving effect to such conversion or other share issuance hereunder
the Holder (together with its affiliates and joint actors) would beneficially own in excess of 9.99% (the “Maximum Percentage”)
of the Common Stock. To the extent the above limitation applies, the determination of whether this Note shall be convertible
(vis-à-vis other convertible, exercisable or exchangeable securities owned by the Holder or any of its affiliates) and of
which such securities shall be convertible (as among all such securities owned by the Holder) shall, subject to such Maximum Percentage
limitation, be made on the basis of the first submission to the Company for conversion, exercise or exchange (as the case may be).
For purposes of the first sentence of this paragraph, the aggregate number of shares of Common Stock beneficially owned by such
Person and its affiliates and joint actors shall include the number of shares of Common Stock issuable upon conversion of this
Note with respect to which the determination is being made, but shall exclude shares of Common Stock which would be issuable upon
(i) conversion of the remaining, unconverted portion of this Note beneficially owned by such Person and its affiliates or joint
actors and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially
owned by such Person or its affiliates and joint actors (including, without limitation, any Series [B][A] Notes, any other convertible
notes or convertible preferred shares), which in each case is subject to a limitation on conversion or exercise analogous to the
limitation contained herein. For the purposes of this paragraph, beneficial ownership and all determinations and calculations (including,
without limitation, with respect to calculations of percentage ownership) shall be determined in accordance with Section 13(d)
of the 1934 Act (as defined in the Securities Purchase Agreement) and the rules and regulations promulgated thereunder, except
as set forth in the preceding sentence. No prior inability to convert this Note pursuant to this paragraph shall have any effect
on the applicability of the provisions of this paragraph with respect to any subsequent determination of convertibility. The provisions
of this paragraph shall be implemented in a manner otherwise than in strict conformity with the terms of this paragraph to correct
this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Maximum Percentage beneficial ownership
limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such Maximum Percentage
limitation. The limitations contained in this paragraph shall apply to a successor Holder of this Note. The holders of Common Stock
shall be third party beneficiaries of this paragraph and the Company may not waive this paragraph without the consent of holders
of a majority of its Common Stock. For any reason at any time, upon the written or oral request of the Holder, the Company shall
within one (1) Business Day confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding,
including by virtue of any prior conversion or exercise of convertible or exercisable securities into Common Stock, including,
without limitation, pursuant to this Note or securities issued pursuant to the Securities Purchase Agreement. By written notice
to the Company, any Holder may increase or decrease the Maximum Percentage to any other percentage not in excess of 9.99% specified
in such notice; provided that (i) any such increase will not be effective until the 61st day after such notice is delivered to
the Company, and (ii) any such increase or decrease will apply only to the Holder sending such notice and not to any other holder
of Notes.

(ii)              
Principal Market Regulation. The Company shall not issue any shares of Common Stock upon conversion of this Note
or otherwise pursuant to the terms of this Note if the issuance of such shares of Common Stock would exceed the aggregate number
of shares of Common Stock which the Company may issue upon conversion or exercise (as the case may be) of the Notes and the Warrants
or otherwise pursuant to the terms of this Note without breaching the Company’s obligations under the rules or regulations
of the Principal Market (the number of shares which may be issued without violating such rules and regulations, including rules
related to the aggregate of offerings under NASDAQ Listing Rule 5635(d), the “Exchange Cap”), except that such
limitation shall not apply in the event that the Company (A) obtains the approval of its stockholders as required by the applicable
rules of the Principal Market for issuances of shares of Common Stock in excess of such amount or (B) obtains a written opinion
from outside counsel to the Company that such approval is not required, which opinion shall be reasonably satisfactory to the Holder.
Until such approval or such written opinion is obtained, no Buyer shall be issued in the aggregate, upon conversion or exercise
(as the case may be) of any Notes or any of the Warrants or otherwise pursuant to the terms of this Note, shares of Common Stock
in an amount greater than the product of (i) the Exchange Cap multiplied by (ii) the quotient of (1) the aggregate original principal
amount of Notes issued to such Buyer pursuant to the Securities Purchase Agreement on both the Series A Closing Date and the Series
B Closing Date (if such Closing Date has occurred) divided by (2) the aggregate original principal amount of all Notes issued to
the Buyers pursuant to the Securities Purchase Agreement both the Series A Closing Date and the Series B Closing Date (if such
Closing Date has occurred) (with respect to each Buyer, the “Exchange Cap Allocation”). In the event that any
Buyer shall sell or otherwise transfer any of such Buyer’s Notes, the transferee shall be allocated a pro rata portion of
such Buyer’s Exchange Cap Allocation with respect to such portion of such Notes so transferred, and the restrictions of the
prior sentence shall apply to such transferee with respect to the portion of the Exchange Cap Allocation so allocated to such transferee.
Upon conversion and exercise in full of a holder’s Notes and Warrants, the difference (if any) between such holder’s
Exchange Cap Allocation and the number of shares of Common Stock actually issued to such holder upon such holder’s conversion
in full of such holder’s Notes and exercise in full of such Warrants shall be allocated to the respective Exchange Cap Allocations
of the remaining holders of Notes and Warrants on a pro rata basis in proportion to the shares of Common Stock underlying the Notes
and Warrants then held by each such holder. In the event that the Company is prohibited from issuing shares of Common Stock pursuant
to this Section 3(d)(ii) (the “Exchange Cap Shares”), the Company shall pay cash (each, an “Exchange
Cap Share Cancellation Amount”) in exchange for the cancellation of such shares of Common Stock at a price equal to the
sum of (i) the product of (x) such number of Exchange Cap Shares and (y) the greatest Closing Sale Price of the Common Stock on
any Trading Day during the period commencing on the date the Holder delivers the applicable Conversion Notice with respect to such
Exchange Cap Shares to the Company and ending on the date of such issuance and payment under this Section 3(d)(ii) and (ii) to
the extent the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction
of a sale by the Holder of Exchange Cap Shares, any brokerage commissions and other out-of-pocket expenses, if any, of the Holder
incurred in connection therewith.

(b)              
Redemption Right. Upon the occurrence of an Event of Default with respect to this Note, the Company shall promptly
deliver written notice thereof via facsimile and overnight courier (with next day delivery specified) (an “Event of Default
Notice”) to the Holder and the Trustee. The obligation of the Company to deliver an Event of Default Notice is in addition
to, and may not be substituted by, the Trustee’s delivery of notice of the same Event of Default to the Holder in accordance
with Section 6.2 of the Indenture. At any time after the earlier of the Holder’s receipt of an Event of Default Notice and
the Holder becoming aware of an Event of Default (such earlier date, the “Event of Default Right Commencement Date”)
and ending (such ending date, the “Event of Default Right Expiration Date”) on the tenth (10th) Trading
Day after the later of (x) the date such Event of Default is cured and (y) the Holder’s receipt of an Event of Default Notice
that includes (I) a reasonable description of the applicable Event of Default, (II) a certification as to whether, in the opinion
of the Company, such Event of Default is capable of being cured and, if applicable, a reasonable description of any existing plan
of the Company to cure such Event of Default and (III) a certification as to the date the Event of Default occurred and the applicable
Event of Default Right Expiration Date, the Holder may elect to redeem all or any portion of the Notes by delivering written notice
thereof (the “Event of Default Redemption Notice”) to the Company and the Trustee, which Event of Default Redemption
Notice shall indicate the portion of the Notes the Holder is electing to redeem. If the Company receives Event of Default Redemption
Notices from holders of Notes electing to redeem at least 20% of the principal amount of the Notes then outstanding prior to the
applicable Event of Default Expiration Date (the date of the Company’s receipt of such notice, the “Event of Default
Redemption Trigger Date”), each portion of this Note subject to redemption by the Company pursuant to this Section 4(b)
shall be redeemed by the Company at a price equal to the greater of (i) the product of (A) the Conversion Amount to be redeemed
multiplied by (B) the Redemption Premium and (ii) the product of (X) the Conversion Rate with respect to the Conversion Amount
in effect at such time as the Holder delivers an Event of Default Redemption Notice multiplied by (Y) the product of (1) the Redemption
Premium multiplied by (2) the greatest Closing Sale Price of the Common Stock on any Trading Day during the period commencing on
the date immediately preceding such Event of Default and ending on the date the Company makes the entire payment required to be
made under this Section 4(b) (the “Event of Default Redemption Price”). Redemptions required by this
Section 4(b) shall be made in accordance with the provisions of Section 11. To the extent redemptions required by this Section
4(b) are deemed or determined by a court of competent jurisdiction to be prepayments of this Note by the Company, such redemptions
shall be deemed to be voluntary prepayments. Notwithstanding anything to the contrary in this Section 4, but subject to Section
3(d), until the Event of Default Redemption Price (together with any Late Charges thereon) is paid in full, the Conversion Amount
submitted for redemption under this Section 4(b) (together with Late Charges thereon) may be converted, in whole or in part, by
the Holder into Common Stock pursuant to Section 3. In the event of a partial redemption of this Note pursuant hereto, the Principal
amount redeemed shall be deducted from the Installment Amount(s) relating to the applicable Installment Date(s) as set forth in
the Event of Default Redemption Notice. In the event of the Company’s redemption of any portion of this Note under this Section
4(b), the Holder’s damages would be uncertain and difficult to estimate because of the parties’ inability to predict
future interest rates and the uncertainty of the availability of a suitable substitute investment opportunity for the Holder. Accordingly,
any redemption premium due under this Section 4(b) is intended by the parties to be, and shall be deemed, a reasonable estimate
of the Holder’s actual loss of its investment opportunity and not as a penalty.

5.                 
RIGHTS UPON FUNDAMENTAL TRANSACTION.


 


(a)               
Assumption. The Company shall not consummate a Fundamental Transaction unless the Successor Entity (if different
than the Company) assumes in writing all of the obligations of the Company under this Note and the other Transaction Documents
in accordance with the provisions of this Section 5(a), including agreements to deliver to each holder of Notes in exchange for
such Notes a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to
the Notes, including, without limitation, having a principal amount and interest rate equal to the principal amounts then outstanding
and the interest rates of the Notes held by such holder, having similar conversion rights as the Notes and having similar ranking
to the Notes. Upon the occurrence of any Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for
(so that from and after the date of such Fundamental Transaction, the provisions of this Note and the other Transaction Documents
referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of
the Company and shall assume all of the obligations of the Company under this Note and the other Transaction Documents with the
same effect as if such Successor Entity had been named as the Company herein. Upon consummation of a Fundamental Transaction, the
Successor Entity (if different than the Company) shall deliver to the Holder confirmation that there shall be issued upon conversion
or redemption of this Note at any time after the consummation of such Fundamental Transaction, in lieu of the shares of the Company’s
Common Stock (or other securities, cash, assets or other property (except such items still issuable under Sections 6 and 14, which
shall continue to be receivable thereafter) issuable upon the conversion or redemption of the Notes prior to such Fundamental Transaction,
such shares of the common stock (or their equivalent) of the Successor Entity (including its Parent Entity) which the Holder would
have been entitled to receive upon the happening of such Fundamental Transaction had this Note been converted immediately prior
to such Fundamental Transaction (without regard to any limitations on the conversion of this Note, except to the extent prohibited
by the rules and regulations of the Principal Market), as adjusted in accordance with the provisions of this Note. Notwithstanding
the foregoing, the Holder may elect, at its sole option, by delivery of written notice to the Company to waive this Section 5(a)
to permit the Fundamental Transaction without the assumption of this Note. The provisions of this Section 5 shall apply similarly
and equally to successive Fundamental Transactions and shall be applied without regard to any limitations on the conversion of
this Note.

(b)              
Redemption Right. No earlier than twenty (20) Trading Days nor later than ten (10) Trading Days prior to the consummation
of a Change of Control, but not prior to the public announcement of such Change of Control, the Company shall deliver written notice
thereof via facsimile and overnight courier to the Holder and the Trustee (a “Change of Control Notice”).
At any time and from time to time during the period commencing on the earlier to occur of (x) any oral or written agreement by
the Company or any of its Subsidiaries, which upon consummation of the transaction contemplated thereby would reasonably be expected
to result in a Change of Control, (y) the Holder becoming aware of a Change of Control and (z) the Holder’s receipt of a
Change of Control Notice, and ending on the later of twenty (20) Trading Days after (A) consummation of such Change of Control
or (B) the date of receipt of such Change of Control Notice, the Holder may require the Company to redeem all or any portion of
the Notes by delivering written notice thereof (“Change of Control Redemption Notice”) to the Company and the
Trustee, which Change of Control Redemption Notice shall indicate the Conversion Amount the Holder is electing to redeem. The portion
of this Note subject to redemption pursuant to this Section 5 shall be redeemed by the Company in cash at a price equal to the
greater of (i) the product of (x) the Change of Control Redemption Premium multiplied by (y) the Conversion Amount being redeemed,
(ii) the product of (x) the Change of Control Redemption Premium multiplied by (y) the product of (A) the Conversion Amount being
redeemed multiplied by (B) the quotient determined by dividing (I) the greatest Closing Sale Price of the Common Stock during the
period beginning on the date immediately preceding the earlier to occur of (1) the consummation of the Change of Control and (2)
the public announcement of such Change of Control and ending on the Trading Day immediately prior to the Trading Day during which
the Company pays the Change of Control Redemption Price (as defined below) to the holders of the Notes (the “Change of
Control Measuring Period”) by (II) the Conversion Price then in effect, or (iii) the
product of (x) the Change of Control Redemption Premium multiplied by (y) the product of (A) the Conversion Amount being redeemed
multiplied by (B) the quotient of (I) the aggregate cash consideration and the aggregate cash value of any non-cash consideration
per share of Common Stock to be paid to the holders of the shares of Common Stock upon consummation of such Change of Control (any
such non-cash consideration constituting publicly-traded securities shall be valued at the highest of the Closing Sale Price of
such securities as of the Trading Day immediately prior to the consummation of such Change of Control, the Closing Sale Price of
such securities on the Trading Day immediately following the public announcement of such proposed Change of Control and the Closing
Sale Price of such securities on the Trading Day immediately prior to the public announcement of such proposed Change of Control)
divided by (II) the Conversion Price then in effect (the “Change of Control Redemption Price”). Redemptions
required by this Section 5 shall be made in accordance with the provisions of Section 11 and shall have priority to payments to
stockholders in connection with such Change of Control. To the extent redemptions required by this Section 5(b) are deemed or determined
by a court of competent jurisdiction to be prepayments of this Note by the Company, such redemptions shall be deemed to be voluntary
prepayments. Notwithstanding anything to the contrary in this Section 5, but subject to Section 3(d), until the Change of Control
Redemption Price (together with Late Charges thereon) is paid in full, the Conversion Amount submitted for redemption under this
Section 5(b) (together with Late Charges thereon) may be converted, in whole or in part, by the Holder into Common Stock pursuant
to Section 3. In the event of a partial redemption of this Note pursuant hereto, the Principal amount redeemed shall be deducted
from the Installment Amount(s) relating to the applicable Installment Date(s) as set forth in the Change of Control Redemption
Notice. In the event of the Company’s redemption of any portion of this Note under this Section 5(b), the Holder’s
damages would be uncertain and difficult to estimate because of the parties’ inability to predict future interest rates and
the uncertainty of the availability of a suitable substitute investment opportunity for the Holder. Accordingly, any redemption
premium due under this Section 5(b) is intended by the parties to be, and shall be deemed, a reasonable estimate of the Holder’s
actual loss of its investment opportunity and not as a penalty.

6.                 
RIGHTS UPON OTHER CORPORATE EVENTS. In addition to and not in substitution for any other rights hereunder, prior
to the consummation of any Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive
securities or other assets with respect to or in exchange for shares of Common Stock (a “Corporate Event”),
the Company shall make appropriate provision to insure that the Holder will thereafter have the right to receive upon a conversion
of this Note in lieu of the shares of Common Stock otherwise receivable upon such conversion, such securities or other assets received
by the holders of shares of Common Stock in connection with the consummation of such Corporate Event in such amounts as the Holder
would have been entitled to receive had this Note initially been issued with conversion rights for the form of such consideration
(as opposed to shares of Common Stock) at a conversion rate for such consideration commensurate with the Conversion Rate. Provision
made pursuant to the preceding sentence shall be in a form and substance satisfactory to the Required Holders. The provisions of
this Section 6 shall apply similarly and equally to successive Corporate Events and shall be applied without regard to any limitations
on the conversion or redemption of this Note.


 


7.                 
RIGHTS UPON ISSUANCE OF OTHER SECURITIES.


 


(a)               
Adjustment of Conversion Price upon Subdivision or Combination of Common Stock. Without limiting any provision of
Section 5, if the Company at any time on or after the Subscription Date subdivides (by any stock split, stock dividend, recapitalization
or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Conversion Price
in effect immediately prior to such subdivision will be proportionately reduced. Without limiting any provision of Section 5, if
the Company at any time on or after the Subscription Date combines (by combination, reverse stock split or otherwise) one or more
classes of its outstanding shares of Common Stock into a smaller number of shares, the Conversion Price in effect immediately prior
to such combination will be proportionately increased. Any adjustment pursuant to this Section 7(a) shall become effective immediately
after the effective date of such subdivision or combination. If any event requiring an adjustment under this Section 7(a) occurs
during the period that a Conversion Price is calculated hereunder, then the calculation of such Conversion Price shall be adjusted
appropriately to reflect such event.


 






    	13



    	 



    

 


(b)              
Holder's Right of Alternative Conversion Price Following Issuance of Certain Options or Convertible Securities. Subject
to Section 4(q) of the Securities Purchase Agreement, in addition to and not in limitation of the other provisions of this Section
7, if the Company in any manner issues or sells or enters into any agreement to issue or sell, any Common Stock, Options or Convertible
Securities (other than the Notes) (any such securities, “Variable Price Securities”) after the Subscription
Date that are issuable pursuant to such agreement or convertible into or exchangeable or exercisable for shares of Common Stock
pursuant to such Options or Convertible Securities, as applicable, at a price which varies or may vary with the market price of
the shares of Common Stock, including by way of one or more reset(s) to a fixed price, but exclusive of such formulations reflecting
customary anti-dilution provisions (such as share splits, share combinations, share dividends and similar transactions) (each of
the formulations for such variable price being herein referred to as, the “Variable Price”), the Company shall
provide written notice thereof via facsimile and overnight courier to the Holder on the date of such agreement and/or the issuance
of such Convertible Securities or Options, as applicable. Subject to Section 4(q) of the Securities Purchase Agreement, from and
after the date the Company enters into such agreement or issues any such Variable Price Securities, the Holder shall have the right,
but not the obligation, in its sole discretion to substitute the Variable Price for the Conversion Price upon conversion of this
Note by designating in the Conversion Notice delivered upon any conversion of this Note that solely for purposes of such conversion
the Holder is relying on the Variable Price rather than the Conversion Price then in effect. The Holder’s election to rely
on a Variable Price for a particular conversion of this Note shall not obligate the Holder to rely on a Variable Price for any
future conversion of this Note.


 


(c)               
Other Events. In the event that the Company (or any Subsidiary) shall take any action to which the provisions hereof
are not strictly applicable, or, if applicable, would not operate to protect the Holder from dilution or if any event occurs of
the type contemplated by the provisions of this Section 7 but not expressly provided for by such provisions (including, without
limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features), then the Company’s
board of directors shall in good faith determine and implement an appropriate adjustment in the Conversion Price so as to protect
the rights of the Holder, provided that no such adjustment pursuant to this Section 7(c) will increase the Conversion Price as
otherwise determined pursuant to this Section 7, provided further that if the Holder does not accept such adjustments as appropriately
protecting its interests hereunder against such dilution, then the Company’s board of directors and the Holder shall agree,
in good faith, upon an independent investment bank of nationally recognized standing to make such appropriate adjustments, whose
determination shall be final and binding and whose fees and expenses shall be borne by the Company.


 


(d)              
Calculations. All calculations under this Section 77 shall be made by rounding to the nearest cent or the nearest
1/100th of a share, as applicable. The number of shares of Common Stock outstanding at any given time shall not include
shares owned or held by or for the account of the Company, and the disposition of any such shares shall be considered an issue
or sale of Common Stock.

8.                 
COMPANY INSTALLMENT CONVERSION OR REDEMPTION.


 


(a)               
General. On each applicable Installment Date, the Company shall pay to the Holder of this Note the applicable Installment
Amount due on such date by converting such Installment Amount in accordance with this Section 8 (a “Company Conversion”);
provided, however, the Company may, at its option as described below, pay all or any part of such Installment Amount by redeeming
such Installment Amount in cash (a “Company Redemption”) or by any combination of a Company Conversion and a
Company Redemption so long as the entire amount of such Installment Amount due shall be converted and/or redeemed by the Company
on the applicable Installment Date, subject to the provisions of this Section 8, provided further that the Company shall not be
entitled to elect a Company Conversion with respect to any portion of such Installment Amount and shall be required to elect and
to pay the entire amount of such Installment Amount in cash pursuant to a Company Redemption if on the applicable Installment Notice
Due Date or on the applicable Installment Date (as the case may be) there is an Equity Conditions Failure (unless waived in writing
by the Holder). Notwithstanding the foregoing, if (i) the Company has elected to effect a Company Conversion pursuant to this Section
88 with respect to the applicable Installment Date, (ii) the Company is permitted pursuant to this Section 8 to effect such Company
Conversion on such Installment Date and (iii) prior to such Installment Date the Holder has delivered (via facsimile or otherwise)
to the Company and the Trustee a written notice (a “Blocker Notice”) (A) stating that such Company Conversion
would result in a violation of Section 3(d)(i) and (B) specifying the portion of the applicable Installment Amount with respect
to which such Company Conversion would result in a violation of Section 3(d)3(d)(i) if such Company Conversion were effected (such
amount so specified is referred to herein as the “Designated Specified Amount”), the Installment Amount
of the Holder for such Installment Date shall be automatically reduced by such Designated Specified Amount; provided, that (x)
at the Holder’s option, at any time prior to the applicable Installment Date, the Holder may reduce the Designated Specified
Amount of shares of Common Stock covered by such Blocker Notice, in whole or in part, by delivery of one or more written notices
to the Company and the Trustee (each, a “Withdrawal Notice”, and each date, a “Withdrawal Notice Date”)
and elect to convert the Designated Specified Amount (or such lesser amount as set forth in the Withdrawal Notice) in accordance
with this Section 8 (each a “Withdrawn Designated Specified Amount”) and (B) the Installment Amount with respect
to such Installment Date shall be automatically increased by an amount equal to the sum of any Withdrawn Designated Specified Amounts
set forth in Withdrawal Notices of the Holder with respect to such Installment Date delivered to the Company prior to such Installment
Date and (y) either (A) if such Installment Date is prior to the Maturity Date, the Installment Amount of the immediately subsequent
Installment Date shall be automatically increased by the Designated Specified Amount (less an amount equal to the sum of any Withdrawn
Designated Specified Amounts set forth in Withdrawal Notices of the Holder delivered with respect to such Installment Date) or
(Y) if such Installment Date is the Maturity Date, such Designated Specified Amount shall automatically increase the Company Redemption
Amount to be paid in cash on the Maturity Date.

(b)              
Mechanics of Company Installment Payments. On or prior to the date which is ten (10) calendar days prior to each
Installment Date (each, an “Installment Notice Due Date”), the Company shall deliver written notice (each, a
“Company Installment Notice” and the date the Trustee and all of the holders receive such notice is referred
to as to the “Company Installment Notice Date”), to the Trustee and each holder of Notes and such Company Installment
Notice shall (i) either (A) confirm that the applicable Installment Amount of such holder’s Note shall be converted, in whole
or in part, pursuant to a Company Conversion or (B) specify the portion of the applicable Installment Amount which the Company
elects, or is required to elect and redeem, pursuant to a Company Redemption (the “Company Redemption Amount”)
and the portion of the applicable Installment Amount, if any, that the Company elects, and is permitted to convert pursuant to
a Company Conversion (the “Company Conversion Amount”), which amounts when added together, must equal the entire
applicable Installment Amount and (ii) if the applicable Installment Amount is to be paid, in whole or in part, pursuant to a Company
Conversion, certify that there is not then an Equity Conditions Failure as of the date of the Company Installment Notice. Each
Company Installment Notice shall be irrevocable. If the Company does not timely deliver a Company Installment Notice in accordance
with this Section 88, then the Company shall be deemed to have delivered an irrevocable Company Installment Notice as of the applicable
Installment Notice Due Date confirming a Company Conversion and shall be deemed to have certified as of the applicable Installment
Notice Due Date that there is not then an Equity Conditions Failure in connection with such Company Conversion.


 


(c)              
Mechanics of Company Conversion. Subject to Section 3(d), if the Company delivers a Company Installment Notice and elects,
or is deemed to have delivered a Company Installment Notice and deemed to have elected, in whole or in part, a Company Conversion
in accordance with Section 8(b), then the remainder of this Section 8(c) shall apply. On each Installment Date, any outstanding
Company Conversion Amount shall be converted as of such Installment Date at the Company Conversion Price and the Company shall,
on the applicable Installment Date, deliver to the Holder’s account with DTC such shares of Common Stock issued upon such
conversion (subject to the reduction contemplated by the immediately following sentence and, if applicable, the last sentence
of this Section 8(c)), provided that the Equity Conditions are then satisfied (or waived in writing by the Holder) on such Installment
Date and a Company Conversion is not otherwise prohibited under any other provision of this Note. If any of the Equity Conditions
are not satisfied (or waived in writing by the Holder) on such Installment Date or a Company Conversion is not otherwise permitted
under any other provision of this Note, then, at the option of the Holder designated in writing to the Company and, in the event
the Holder elects a redemption, the Trustee (i) the Holder may require the Company to do any one or more of the following: the
Company shall redeem in cash, as designated by the Holder, all or any part of the Company Conversion Amount (together with any
Designated Specified Amount specified in a Blocker Notice delivered with respect to any Company Conversion for such Installment
Date) (such designated amount, together with such Designated Specified Amount, if any, is referred to as the “Designated
Redemption Amount”) and the Company shall pay to the Holder within three (3) Business Days of such Installment Date,
by wire transfer of immediately available funds, an amount in cash equal to 115% of such Designated Redemption Amount, and/or
(ii) cause the Company Conversion to be null and void with respect to such Designated Redemption Amount; provided, however, the
Conversion Price for such Designated Redemption Amount shall thereafter be adjusted to equal the lesser of (A) the Company Conversion
Price as in effect on the date on which the Holder voided the Company Conversion and (B) the Company Conversion Price that would
be in effect on the date on which the Holder delivers a Conversion Notice relating thereto as if such date was an Installment
Date. The Holder shall be entitled to all the rights of a holder of this Note with respect to such Designated Redemption Amount.
If the Company fails to redeem any Designated Redemption Amount by the third (3rd) Trading Day following the applicable
Installment Date by payment of such amount on the applicable Installment Date, then the Holder shall have the rights set forth
in Section 11(a) as if the Company failed to pay the applicable Company Installment Redemption Price (as defined below) and all
other rights under this Note. Notwithstanding anything to the contrary in this Section 8(c), but subject to Section 3(d), until
the Company delivers Common Stock representing the Company Conversion Amount to the Holder, the Company Conversion Amount may
be converted, in whole or in part, by the Holder into Common Stock pursuant to Section 3, in which event the Company Conversion
Amount so converted shall be deducted from the Installment Amount(s) relating to the applicable Installment Date(s) as set forth
in the applicable Conversion Notice. The Company shall pay any and all taxes that may be payable with respect to the issuance
and delivery of any shares of Common Stock in any Company Conversion hereunder.


 






    	16



    	 



    

 


(d)              
Mechanics of Company Redemption. If the Company elects, or is required to elect, a Company Redemption, in whole or
in part, in accordance with Section 8(b), then the Company Redemption Amount, if any, which is to be paid to the Holder on the
applicable Installment Date shall be redeemed by the Company, or at the Company’s election, by the Trustee, on such Installment
Date, and the Company, or Trustee, as applicable, shall pay to the Holder on such Installment Date, by wire transfer of immediately
available funds in an amount in cash (the “Company Installment Redemption Price”) equal to the applicable Company
Redemption Amount. If the Company fails to redeem the applicable Company Redemption Amount on the applicable Installment Date,
then, at the option of the Holder designated in writing to the Company and the Trustee (any such designation shall be a “Conversion
Notice” for purposes of this Note), the Holder may require the Company to convert all or any part of the Company Redemption
Amount at the Company Conversion Price (determined as of the date of such designation). Conversions required by this Section 8(d)8(d)
shall be made in accordance with the provisions of Section 3(c). Notwithstanding anything to the contrary in this Section 8(d),
but subject to Section 3(d), until the Company Installment Redemption Price (together with any Late Charges thereon) is paid in
full, the Company Redemption Amount (together with any Late Charges thereon) may be converted, in whole or in part, by the Holder
into Common Stock pursuant to Section 3. In the event the Holder elects to convert all or any portion of the Company Redemption
Amount prior to the applicable Installment Date as set forth in the immediately preceding sentence, the portion of the Company
Redemption Amount so converted shall be deducted from the Installment Amounts relating to the applicable Installment Date(s) as
set forth in the applicable Conversion Notice. Redemptions required by this Section 8(d) shall be made in accordance with the provisions
of Section 11.


 


(e)               
Deferred Installment Amount. Notwithstanding any provision of this Section 8 to the contrary, the Holder may, at
its option and in its sole discretion, deliver a written notice to the Company and the Trustee no later than the Trading Day immediately
prior to the applicable Installment Date (the “Installment Notification Deadline Date”) electing to have the
payment of all or any portion of an Installment Amount payable on such Installment Date deferred (such amount deferred, the “Deferral
Amount”) until any subsequent Installment Date selected by the Holder, in its sole discretion,
in which case, the Deferral Amount shall be added to, and become part of, such subsequent Installment Amount and such Deferral
Amount shall continue to accrue Interest hereunder. Any notice delivered by the Holder pursuant to this Section 8(d) shall set
forth (i) the Deferral Amount and (ii) the date that such Deferral Amount shall now be payable.


 


(f)               
Conversion of Installment Amounts. Notwithstanding anything herein to the contrary, during the period commencing
on an Installment Date (a “Current Installment Date”) and ending on the Trading Day immediately prior to the
next Installment Date, at the option of the Holder, at one or more times, the Holder may convert other Installment Amounts, in
whole or in part, at the Company Conversion Price of such Current Installment Date in accordance with the conversion procedures
set forth in Section 3 hereunder, mutatis mutandis. Notwithstanding the foregoing, with respect to any Installment Date,
the Holder may not elect to effect any conversion of any other Installment Amounts pursuant to this Section 8(f), in the aggregate,
in excess of the sum of four (4) other Installment Amounts (or, if the Company has elected to effect a Company Conversion with
respect to the entire Installment Amount of such Installment Date, three (3) other Installment Amounts) (collectively, the “Installment
Adjustment Limitation”); provided, further that if any Event of Default described in Sections 4(a)(vi) through 4(a)(viii)
has occurred and is continuing (or, if by replacing “Restricted Subsidiary” with “Subsidiary” therein,
would have occurred or would be continuing), the Installment Adjustment Limitation shall no longer apply to this Note and the “Company
Conversion Price” thereafter for purposes of this Section 8(f) shall equal the lesser of (x) the Company Conversion Price
with respect to such Current Installment Date and (y) the applicable Installment Adjustment Conversion Price.

9.                 
NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate
of Incorporation (as defined in the Securities Purchase Agreement), Bylaws (as defined in the Securities Purchase Agreement) or
through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities,
or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Note, and will
at all times in good faith carry out all of the provisions of this Note and take all action as may be required to protect the rights
of the Holder of this Note. Without limiting the generality of the foregoing, the Company (i) shall not increase the par value
of any shares of Common Stock receivable upon conversion of this Note above the Company Conversion Price with respect to the Installment
Date occurring in the calendar month in which such increase occurs, (ii) shall take all such actions as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the
conversion of this Note, and (iii) shall, so long as any of the Notes are outstanding, take all action reasonably necessary to
reserve and keep available out of its authorized and unissued shares of Common Stock, solely for the purpose of effecting the conversion
of the Notes, the maximum number of shares of Common Stock as shall from time to time be necessary to effect the conversion of
the Notes then outstanding (without regard to any limitations on conversion).


 


10.             
RESERVATION OF AUTHORIZED SHARES.


 


(a)               
Reservation. The Company shall initially reserve out of its authorized and unissued Common Stock and for so long
as any of the Notes are outstanding, the Company shall take all action necessary to reserve and keep available out of its authorized
and unissued Common Stock, such number of shares of Common Stock for each of the Notes equal to (x) if prior to the earlier to
occur of (A) the Stockholder Approval Date (as defined in the Securities Purchase Agreement) and (B) the Series B Closing Expiration
Date (as defined in the Securities Purchase Agreement) (such earlier date, the “Reservation Requirement Date”),
30,000,000 shares of Common Stock for issuance upon conversion and/or upon payment of any other amounts due under the Notes and
(y) if on or after the Reservation Requirement Date, the sum of (i) 125% of the maximum number of Conversion Shares issued and
issuable pursuant to the Notes (determined without taking into account any limitations on the conversion of the Notes set forth
therein and assuming that the Notes are convertible at the Company Conversion Price with respect to the Installment Date of the
calendar month in which such time of determination occurs and all Series B Notes issuable pursuant to the Securities Purchase Agreement
have been issued) and (ii) 125% of the maximum number of Interest Shares (as defined in the Securities Purchase Agreement) issued
and issuable pursuant to the terms of the Notes from the Series A Closing Date through the maturity date of the Series B Notes
(determined without taking into account any limitations on the conversion of the Notes set forth therein and assuming that all
Series B Notes issuable pursuant to the Securities Purchase Agreement have been issued) (collectively, the “Required Reserve
Amount”). The initial number of shares of Common Stock reserved for conversions of the Notes and each increase in the
number of shares so reserved shall be allocated pro rata among the holders of the Notes based on the original principal amount
of the Notes held by each holder on the Series A Closing Date or increase in the number of reserved shares (as the case may be)
(the “Authorized Share Allocation”). In the event that a holder shall sell or otherwise transfer any of such
holder’s Notes, each transferee shall be allocated a pro rata portion of such holder’s Authorized Share Allocation.
Any shares of Common Stock reserved and allocated to any Person which ceases to hold any Notes shall be allocated to the remaining
holders of Notes, pro rata based on the principal amount of the Notes then held by such holders.

(b)              
Insufficient Authorized Shares. If, notwithstanding Section 10(a), and not in limitation thereof, at any time while
any of the Notes remain outstanding the Company does not have a sufficient number of authorized and otherwise unreserved shares
of Common Stock to satisfy its obligation to reserve for issuance upon conversion of the Notes at least a number of shares of Common
Stock equal to the Required Reserve Amount (an “Authorized Share Failure”), then the Company shall immediately
take all action reasonably necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient
to allow the Company to reserve the Required Reserve Amount for the Notes then outstanding. Without limiting the generality of
the foregoing sentence, as soon as practicable after the date of the occurrence of an Authorized Share Failure, but in no event
later than ninety (90) days after the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its stockholders
for the approval of an increase in the number of authorized shares of Common Stock. In connection with such meeting, the Company
shall provide each stockholder with a proxy statement and shall use its reasonable best efforts to solicit its stockholders’
approval of such increase in authorized shares of Common Stock and to cause its board of directors to recommend to the stockholders
that they approve such proposal. In the event that the Company is prohibited from issuing shares of Common Stock upon any conversion
due to the failure by the Company to have sufficient shares of Common Stock available out of the authorized but unissued shares
of Common Stock (such unavailable number of shares of Common Stock, the “Authorization Failure Shares”), in
lieu of delivering such Authorization Failure Shares to the Holder, the Company shall pay cash (each, an “Authorized Failure
Share Cancellation Amount”) in exchange for the redemption of such portion of the Conversion Amount convertible into
such Authorized Failure Shares at an amount equal to the sum of (i) the product of (x) such number of Authorization Failure Shares
and (y) the greatest Closing Sale Price of the Common Stock on any Trading Day during the period commencing on the date the Holder
delivers the applicable Conversion Notice with respect to such Authorization Failure Shares to the Company and ending on the date
of such issuance and payment under this Section 10(b) and (ii) to the extent the Holder purchases (in an open market transaction
or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of Authorization Failure Shares, any brokerage
commissions and other out-of-pocket expenses, if any, of the Holder incurred in connection therewith. Nothing contained in Section
10(a) or this Section 10(b) shall limit any obligations of the Company under any provision of the Securities Purchase Agreement.

REDEMPTIONS.


 


(a)               
Mechanics. The Company, or at the Company’s direction, the Trustee, shall deliver the applicable Event of Default
Redemption Price to the Holder in cash within five (5) Business Days after the later of (x) the Company’s receipt of the
Holder’s Event of Default Redemption Notice and (y) the applicable Event of Default Redemption Trigger Date. If the Holder
has submitted a Change of Control Redemption Notice in accordance with Section 5(b), the Company, or at the Company’s direction,
the Trustee, shall deliver the applicable Change of Control Redemption Price to the Holder in cash concurrently with the consummation
of such Change of Control if such notice is received prior to the consummation of such Change of Control and within five (5) Business
Days after the Company’s receipt of such notice otherwise. The Company, or at the Company’s direction, the Trustee,
shall deliver the applicable Company Installment Redemption Price to the Holder in cash on the applicable Installment Date. In
the event of a redemption of less than all of the Conversion Amount of this Note, the Company shall promptly cause to be issued,
following authentication of such new Note, and delivered to the Holder a new Note (in accordance with Section 17(d)) representing
the outstanding Principal which has not been redeemed. In the event that the Company does not pay the applicable Redemption Price
to the Holder within the time period required, at any time thereafter and until the Company pays such unpaid Redemption Price in
full, the Holder shall have the option, in lieu of redemption, to require the Company to promptly return to the Holder all or any
portion of this Note representing the Conversion Amount that was submitted for redemption and for which the applicable Redemption
Price (together with any Late Charges thereon) has not been paid. Notwithstanding anything herein to the contrary, in connection
with any redemption hereunder at a time the Holder is entitled to receive a cash payment under any of the other Transaction Documents,
at the option of the Holder delivered in writing to the Company, the applicable Redemption Price hereunder shall be increased by
the amount of such cash payment owed to the Holder, in whole or in part as specified in such writing, under such other Transaction
Document and, upon payment in full or conversion in accordance herewith, shall satisfy the Company’s payment obligation under
such other Transaction Document. Upon the Company’s receipt of such notice, (x) the applicable Redemption Notice shall be
null and void with respect to such Conversion Amount and (y) the Company shall immediately return this Note, or issue a new, duly
authenticated Note (in accordance with Section 17(d)), to the Holder, and in each case the principal amount of this Note or
such new Note (as the case may be) shall be increased by an amount equal to the difference between (1) the applicable Event of
Default Redemption Price, Change of Control Redemption Price or Company Installment Redemption Price, as the case may be, minus
(2) the Conversion Amount submitted for redemption and (z) the Conversion Price of this Note or such new Notes (as the case may
be) shall be automatically adjusted with respect to each conversion effected thereafter by the Holder to the lowest of (A) the
lowest Company Conversion Price of the Installment Dates occurring during the period commencing on the date the Holder delivers
the applicable Redemption Notice and ending on the date the applicable Redemption Notice is voided and (B) 85% of the lowest Closing
Bid Price of the Common Stock during the period beginning on and including the date on which the applicable Redemption Notice is
delivered to the Company and ending on and including the date on which the applicable Redemption Notice is voided. The Holder’s
delivery of a notice voiding a Redemption Notice and exercise of its rights following such notice shall not affect the Company’s
obligations to make any payments of Late Charges which have accrued prior to the date of such notice with respect to the Conversion
Amount subject to such notice.

(b)

the Company shall immediately, but no later than one (1) Business Day of its receipt thereof, forward to the Holder by facsimile
a copy of such notice (whether or not the Company agrees that such event or occurrence has occurred and/or is continuing). Upon
the Company’s receipt of notice from any of the holders of the Other Notes for redemption or repayment as a result of an
event or occurrence substantially similar to the events or occurrences described in Section 4(b) or Section 5(b) (each, an “Other
Redemption Notice”), the Company shall immediately, but no later than one (1) Business Day of its receipt thereof, forward
to the Holder by facsimile a copy of such notice (whether or not the Company agrees that such event or occurrence has occurred
and/or is continuing). If the Company receives a Redemption Notice and one or more Other Redemption Notices, during the seven (7)
Business Day period beginning on and including the date which is three (3) Business Days prior to the Company’s receipt of
the Holder’s applicable Redemption Notice and ending on and including the date which is three (3) Business Days after the
Company’s receipt of the Holder’s applicable Redemption Notice and the Company is unable to redeem all principal, interest
and other amounts designated in such Redemption Notice and such Other Redemption Notices received during such seven (7) Business
Day period, then the Company shall redeem a pro rata amount from each holder of the Notes (including the Holder) based on the principal
amount of the Notes submitted for redemption pursuant to such Redemption Notice and such Other Redemption Notices received by the
Company during such seven (7) Business Day period.


 


12.

to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security
being required. The Company shall provide all information and documentation to the Holder that is requested by the Holder to enable
