at Option of Holder. Each share of Preferred Stock shall be convertible, at any time and from time to time from and after the
Original Issue Date at the option of the Holder thereof, into that number of shares of Common Stock (subject to the limitations

include the Holder’s complete and accurate DWAC and prime broker delivery information, attached hereto as Annex A
(a "Notice of Conversion"). Each Notice of Conversion shall specify the number of shares of Preferred Stock to
be converted, the number of shares of Preferred Stock owned prior to the conversion at issue, the number of shares of Preferred
Stock owned subsequent to the conversion at issue and the date on which such conversion is to be effected, which date may not be
prior to the date the applicable Holder delivers by facsimile such Notice of Conversion to the Corporation (such date, the "Conversion
Date"). If no Conversion Date is specified in a Notice of Conversion, the Conversion Date shall be the date that such
Notice of Conversion to the Corporation is deemed delivered hereunder. No ink-original Notice of Conversion shall be required,
nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Conversion form be required.
The calculations and entries set forth in the Notice of Conversion shall control in the absence of manifest or mathematical
error. To effect conversions of shares of Preferred Stock, a Holder shall not be required to surrender the certificate(s) representing
the shares of Preferred Stock to the Corporation unless all of the shares of Preferred Stock represented thereby are so converted,
in which case such Holder shall deliver the certificate representing such shares of Preferred Stock promptly following the Conversion
Date at issue. Shares of Preferred Stock converted into Common Stock or redeemed in accordance with the terms hereof shall be canceled
and shall not be reissued.


 


(b)          Conversion
Price. The conversion price for the Preferred Stock shall equal $0.20, subject to adjustment herein (the "Conversion
Price").


 


(c)          Mechanics
of Conversion.


 


i.            Delivery
of Conversion Shares Upon Conversion. Not later than three (3) Trading Days after each Conversion Date (the "Share
Delivery Date"), the Corporation shall deliver, or cause to be delivered, to the converting Holder (A) the number of Conversion
Shares being acquired upon the conversion of the Preferred Stock, which Conversion Shares shall be free of restrictive legends
and trading restrictions and (B) a bank check in the amount of accrued and unpaid dividends, if any, in accordance with Section
3. The Corporation shall deliver the Conversion Shares electronically through the Depository Trust Company or another established
clearing corporation performing similar functions.


 


ii.         Failure
to Deliver Conversion Shares. If, in the case of any Notice of Conversion, such Conversion Shares are not delivered to or as
directed by the applicable Holder by the Share Delivery Date, the Holder shall be entitled to elect by written notice to the Corporation
at any time on or before its receipt of such Conversion Shares, to rescind such Conversion, in which event the Corporation shall
promptly return to the Holder any original Preferred Stock certificate delivered to the Corporation and the Holder shall promptly
return to the Corporation the Conversion Shares issued to such Holder pursuant to the rescinded Conversion Notice. Failure by a
Holder to deliver to the Corporation a complete and accurate Notice of Conversion shall result in the adjustment of the Share Delivery
Date by adding one additional Trading Day for the benefit of the Corporation to comply with this Section 6(c) for each day that
such Holder fails to provide all of the information necessary for the Corporation to cause the Conversion Shares to be delivered
to such Holder.


 




    	 	6	 



     


    

 


iii.         Obligation
Absolute; Partial Liquidated Damages. The Corporation’s obligation to issue and deliver the Conversion Shares upon conversion
of Preferred Stock in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by
a Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against
any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach
or alleged breach by such Holder or any other Person of any obligation to the Corporation or any violation or alleged violation
of law by such Holder or any other person, and irrespective of any other circumstance which might otherwise limit such obligation
of the Corporation to such Holder in connection with the issuance of such Conversion Shares; provided, however, that
such delivery shall not operate as a waiver by the Corporation of any such action that the Corporation may have against such Holder.
If the Corporation fails to deliver to a Holder such Conversion Shares pursuant to Section 6(c)(i) on the second Trading Day after
the Share Delivery Date (subject to Section 6(c)(ii)) applicable to such conversion, the Corporation shall pay to such Holder,
in cash, as liquidated damages and not as a penalty, for each $5,000 of Stated Value of Preferred Stock being converted, $50 per
Trading Day (increasing to $100 per Trading Day on the third Trading Day and increasing to $200 per Trading Day on the sixth Trading
Day after such damages begin to accrue) for each Trading Day after such second Trading Day after the Share Delivery Date (subject
to Section 6(c)(ii)) until such Conversion Shares are delivered or Holder rescinds such conversion. Nothing herein shall limit
a Holder's right to pursue actual damages for the Corporation's failure to deliver Conversion Shares within the period specified
herein and such Holder shall have the right to pursue all remedies available to it hereunder, at law or in equity including, without
limitation, a decree of specific performance and/or injunctive relief. The exercise of any such rights shall not prohibit a Holder
from seeking to enforce damages pursuant to any other Section hereof or under applicable law.


 


iv.         Compensation
for Buy-In on Failure to Timely Deliver Conversion Shares Upon Conversion. In addition to any other rights available to the
Holder, if the Corporation fails for any reason to deliver to a Holder the applicable Conversion Shares by the Share Delivery Date
pursuant to Sections 6(c)(i) and 6(c)(ii), and if after such Share Delivery Date such Holder is required by its brokerage firm
to purchase (in an open market transaction or otherwise), or the Holder’s brokerage firm otherwise purchases, shares of Common
Stock to deliver in satisfaction of a sale by such Holder of the Conversion Shares which such Holder was entitled to receive upon
the conversion relating to such Share Delivery Date (a "Buy-In"), then the Corporation shall (A) pay in cash to
such Holder (in addition to any other remedies available to or elected by such Holder) the amount, if any, by which (x) such Holder’s
total purchase price (including any brokerage commissions) for the Common Stock so purchased exceeds (y) the product of (1) the
aggregate number of shares of Common Stock that such Holder was entitled to receive from the conversion at issue multiplied by
(2) the actual sale price at which the sell order giving rise to such purchase obligation was executed (including any brokerage
commissions) and (B) at the option of such Holder, either reissue (if surrendered) the shares of Preferred Stock equal to the number
of shares of Preferred Stock submitted for conversion (in which case, such conversion shall be deemed rescinded) or deliver to
such Holder the number of shares of Common Stock that would have been issued if the Corporation had timely complied with its delivery
requirements under Sections 6(c)(i) and 6(c)(ii). For example, if a Holder purchases shares of Common Stock having a total purchase
price of $11,000 to cover a Buy-In with respect to an attempted conversion of shares of Preferred Stock with respect to which the
actual sale price of the Conversion Shares (including any brokerage commissions) giving rise to such purchase obligation was a
total of $10,000 under clause (A) of the immediately preceding sentence, the Corporation shall be required to pay such Holder $1,000.
The Holder shall provide the Corporation written notice indicating the amounts payable to such Holder in respect of the Buy-In
and, upon request of the Corporation, evidence of the amount of such loss. Nothing herein shall limit a Holder’s right to
pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance
and/or injunctive relief with respect to the Corporation’s failure to timely deliver the Conversion Shares upon conversion
of the shares of Preferred Stock as required pursuant to the terms hereof.


 




    	 	7	 



     


    

 


v.           Reservation
of Shares Issuable Upon Conversion. The Corporation covenants that it will at all times reserve and keep available out of its
authorized and unissued shares of Common Stock for the sole purpose of issuance upon conversion of the Preferred Stock as herein
provided, free from preemptive rights or any other actual contingent purchase rights of Persons other than the Holder (and the
other holders of the Preferred Stock), not less than such aggregate number of shares of the Common Stock as shall (subject to the
terms and conditions set forth in the Purchase Agreement) be issuable (taking into account the adjustments and restrictions of
Section 7) upon the conversion of the then outstanding shares of Preferred Stock. The Corporation covenants that all shares of
Common Stock that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid and nonassessable.


 


vi.         Fractional
Shares. No fractional shares or scrip representing fractional shares shall be issued upon the conversion of the Preferred Stock.
As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such conversion, the Corporation shall
at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied
by the Conversion Price or round up to the next whole share.


 


vii.         Transfer
Taxes and Expenses. The issuance of Conversion Shares on conversion of this Preferred Stock shall be made without charge to
any Holder for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such Conversion
Shares, provided that the Corporation shall not be required to pay any tax that may be payable in respect of any transfer involved
in the issuance and delivery of any such Conversion Shares upon conversion in a name other than that of the Holders of such shares
of Preferred Stock and the Corporation shall not be required to issue or deliver such Conversion Shares unless or until the Person
or Persons requesting the issuance thereof shall have paid to the Corporation the amount of such tax or shall have established
to the satisfaction of the Corporation that such tax has been paid. The Corporation shall pay all Transfer Agent fees required
for same-day processing of any Notice of Conversion and all fees to the Depository Trust Company (or another established clearing
corporation performing similar functions) required for same-day electronic delivery of the Conversion Shares.


 




    	 	8	 



     


    

 


(d)          Beneficial
Ownership Limitation. The Corporation shall not effect any conversion of the Preferred Stock, and a Holder shall not
have the right to convert any portion of the Preferred Stock, to the extent that, after giving effect to the conversion set forth
on the applicable Notice of Conversion, such Holder (together with such Holder’s Affiliates, and any Persons acting as a
group together with such Holder or any of such Holder’s Affiliates) would beneficially own in excess of the Beneficial Ownership
Limitation (as defined below).  For purposes of the foregoing sentence, the number of shares of Common Stock beneficially
owned by such Holder and its Affiliates shall include the number of shares of Common Stock issuable upon conversion of the Preferred
Stock with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which are
issuable upon (i) conversion of the remaining, unconverted Stated Value of Preferred Stock beneficially owned by such Holder or
any of its Affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the
Corporation subject to a limitation on conversion or exercise analogous to the limitation contained herein (including, without
limitation, the Preferred Stock or the Warrants) beneficially owned by such Holder or any of its Affiliates.  Except as set
forth in the preceding sentence, for purposes of this Section 6(d), beneficial ownership shall be calculated in accordance with
Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the Holder that
the Corporation is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act
and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation
contained in this Section 6(d) applies, the determination of whether the Preferred Stock is convertible (in relation to other
securities owned by such Holder together with any Affiliates) and of how many shares of Preferred Stock are convertible shall
be in the sole discretion of such Holder, and the submission of a Notice of Conversion shall be deemed to be such Holder’s
determination of whether the shares of Preferred Stock may be converted (in relation to other securities owned by such Holder
together with any Affiliates) and how many shares of the Preferred Stock are convertible, in each case subject to the Beneficial
Ownership Limitation. To ensure compliance with this restriction, each Holder will be deemed to represent to the Corporation each
time it delivers a Notice of Conversion that such Notice of Conversion has not violated the restrictions set forth in this paragraph
and the Corporation shall have no obligation to verify or confirm the accuracy of such determination. In
addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of
the Exchange Act and the rules and regulations promulgated thereunder.
For purposes of this Section 6(d), in determining the number of outstanding shares of Common Stock, a Holder may rely
on the number of outstanding shares of Common Stock as stated in the most recent of the following: (i) the Corporation’s
most recent periodic or annual report filed with the Commission, as the case may be, (ii) a more recent public announcement by
the Corporation or (iii) a more recent written notice by the Corporation or the Transfer Agent setting forth the number of shares
of Common Stock outstanding.  Upon the written request (which may be via email) of a Holder, the Corporation shall within
two Trading Days confirm orally and in writing to such Holder the number of shares of Common Stock then outstanding.  In
any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise
of securities of the Corporation, including the Preferred Stock, by such Holder or its Affiliates since the date as of which such
number of outstanding shares of Common Stock was reported. The "Beneficial Ownership Limitation" shall be 4.99%
of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock
issuable upon conversion of Preferred Stock held by the applicable Holder. A Holder, upon notice to the Corporation, may increase
or decrease the Beneficial Ownership Limitation provisions of this Section 6(d) applicable to its Preferred Stock provided that
the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of the Common Stock outstanding immediately
after giving effect to the issuance of shares of Common Stock upon conversion of this Preferred Stock held by the Holder and the
provisions of this Section 6(d) shall continue to apply. Any such increase in the Beneficial Ownership Limitation will not be
effective until the 61st day after such notice is delivered to the Corporation and shall only apply to such Holder
and no other Holder. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict
conformity with the terms of this Section 6(d) to correct this paragraph (or any portion hereof) which may be defective or inconsistent
with the intended Beneficial Ownership Limitation contained herein or to make changes or supplements necessary or desirable to
properly give effect to such limitation. The
limitations contained in this paragraph shall apply to a successor holder of Preferred Stock.

Section 7. Certain
Adjustments.


 


(a)          Stock
Dividends and Stock Splits. If the Corporation, at any time while this Preferred Stock is outstanding: (i) pays a stock dividend
or otherwise makes a distribution or distributions payable in shares of Common Stock on shares of Common Stock or any other Common
Stock Equivalents (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Corporation upon conversion
of, or payment of a dividend on, this Preferred Stock), (ii) subdivides outstanding shares of Common Stock into a larger number
of shares, (iii) combines (including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number
of shares, or (iv) issues, in the event of a reclassification of shares of the Common Stock, any shares of capital stock of the
Corporation, then the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of
Common Stock (excluding any treasury shares of the Corporation) outstanding immediately before such event, and of which the denominator
shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to this Section
7(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend
or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.


 




    	 	10	 



     


    

 


(b)          [Reserved].


 


(c)          Subsequent
Rights Offerings. In addition to any adjustments pursuant to Section 7(a) above, if at any time the Corporation grants, issues
or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record
holders of any class of shares of Common Stock (the "Purchase Rights"), then the Holder of will be entitled to
acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired
if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of such Holder’s Preferred
Stock (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation)
immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such
record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or
sale of such Purchase Rights (provided, however, to the extent that the Holder’s right to participate in any such Purchase
Right would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate
in such Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right
to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until the earlier of (a) such time,
if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation and (b) solely with
respect to rights to purchase stock, warrants, securities or other property, the expiration of the applicable rights offering for
such Purchase Rights (in which case such Purchase Rights shall be cancelled and terminated)).


 


(d)          Pro
Rata Distributions. During such time as this Preferred Stock is outstanding, if the Corporation shall declare or make any dividend
or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of
capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by
way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a
"Distribution"), at any time after the issuance of this Preferred Stock, then, in each such case, the Holder shall
be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder
had held the number of shares of Common Stock acquirable upon complete conversion of this Preferred Stock (without regard to any
limitations on conversion hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date
of which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of shares
of Common Stock are to be determined for the participation in such Distribution (provided, however, to the extent
that the Holder's right to participate in any such Distribution would result in the Holder exceeding the Beneficial Ownership Limitation,
then the Holder shall not be entitled to participate in such Distribution to such extent (or in the beneficial ownership of any
shares of Common Stock as a result of such Distribution to such extent) and the portion of such Distribution shall be held in abeyance
for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial
Ownership Limitation).


 




    	 	11	 



     


    

 


(e)          Fundamental
Transaction. If, at any time while this Preferred Stock is outstanding, (i) the Corporation, directly or indirectly, in one
or more related transactions effects any merger or consolidation of the Corporation with or into another Person, (ii) the Corporation,
directly or indirectly, effects any sale of all or substantially all of its assets in one or a series of related transactions,
(iii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether by the Corporation or another Person) is
completed pursuant to which holders of Common Stock are permitted to sell, tender or exchange their shares for other securities,
cash or property and has been accepted by the holders of 50% or more of the outstanding Common Stock, (iv) the Corporation, directly
or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization of the Common
Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other
securities, cash or property, (v) the Corporation, directly or indirectly, in one or more related transactions consummates a stock
or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off
or scheme of arrangement) with another Person whereby such other Person acquires more than 50% of the outstanding shares of Common
Stock (not including any shares of Common Stock held by the other Person or other Persons making or party to, or associated or
affiliated with the other Persons making or party to, such stock or share purchase agreement or other business combination) (each
a "Fundamental Transaction"), then, upon any subsequent conversion of this Preferred Stock, the Holder shall have
the right to receive, for each Conversion Share that would have been issuable upon such conversion immediately prior to the occurrence
of such Fundamental Transaction (without regard to any limitation in Section 6(d) on the conversion of this Preferred Stock), the
number of shares of Common Stock of the successor or acquiring corporation or of the Corporation, if it is the surviving corporation,
and any additional consideration (the "Alternate Consideration") receivable by holders of Common Stock as a result
of such Fundamental Transaction for each share of Common Stock for which this Preferred Stock is convertible immediately prior
to such Fundamental Transaction (provided, however, that to the extent that a Holder’s or any of its Affiliate’s, singly
or in the aggregate, right to receive such shares would result in exceeding the Beneficial Ownership Limitation, then the Holder
shall not be entitled to receive such shares to such extent (or to beneficially own any shares of common stock of the Corporation
or its equivalent); however, such shares or securities shall be held in abeyance for the benefit of such Holder until such time,
if ever, as its right thereto would not result in such Holder exceeding the Beneficial Ownership Limitation, at which time the
Holder shall be delivered such shares or securities up to, but not exceeding, such Beneficial Ownership Limitation). For purposes
of any such conversion, the determination of the Conversion Price shall be appropriately adjusted to apply to such Alternate Consideration
based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction,
and the Corporation shall apportion the Conversion Price among the Alternate Consideration in a reasonable manner reflecting the
relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to
the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as
to the Alternate Consideration it receives upon any conversion of this Preferred Stock following such Fundamental Transaction.
To the extent necessary to effectuate the foregoing provisions, any successor to the Corporation or surviving entity in such Fundamental
Transaction shall file a new Certificate of Designation with the same terms and conditions and issue to the Holders new preferred
stock consistent with the foregoing provisions and evidencing the Holders’ right to convert such preferred stock into Alternate
Consideration. The Corporation shall cause any successor entity in a Fundamental Transaction in which the Corporation is not the
survivor (the "Successor Entity") to assume in writing all of the obligations of the Corporation under this Certificate
of Designation and the other Transaction Documents (as defined in the Purchase Agreement) in accordance with the provisions of
this Section 7(e) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the
Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the holder of this Preferred
Stock, deliver to the Holder in exchange for this Preferred Stock a security of the Successor Entity evidenced by a written instrument
substantially similar in form and substance to this Preferred Stock which is convertible for a corresponding number of shares of
capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable
upon conversion of this Preferred Stock (without regard to any limitations on the conversion of this Preferred Stock) prior to
such Fundamental Transaction, and with a conversion price which applies the conversion price hereunder to such shares of capital
stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the
value of such shares of capital stock, such number of shares of capital stock and such conversion price being for the purpose of
protecting the economic value of this Preferred Stock immediately prior to the consummation of such Fundamental Transaction), and
which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such 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 Certificate of Designation and the other Transaction Documents referring to the "Corporation"
shall refer instead to the Successor Entity), and may exercise every right and power of the Corporation and shall assume all of
the obligations of the Corporation under this Certificate of Designation and the other Transaction Documents with the same effect
as if such Successor Entity had been named as the Corporation herein.

For purposes of this Section 7, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall
be the sum of the number of shares of Common Stock (excluding any treasury shares of the Corporation) issued and outstanding.

i.     Adjustment

share exchange whereby the Common Stock is converted into other securities, cash or property or (E) the Corporation shall authorize
the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Corporation, then, in each case where

reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date
as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common
Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share
exchange, provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect the
validity of the corporate action required to be specified in such notice. To the extent that any notice provided hereunder constitutes,
or contains, material, non-public information regarding the Corporation or any of the Subsidiaries, the Corporation shall file
such notice with the Commission pursuant to a Current Report on Form 8-K in the time required by applicable law, rule and regulation
or within the time required under such other Commission form. The Holder shall remain entitled to convert the Conversion Amount
of this Preferred Stock (or any part hereof) during the 20-day period commencing on the date of such notice through the effective
date of the event triggering such notice except as may otherwise be expressly set forth herein.

(d)          Governing
Law. All questions concerning the construction, validity, enforcement and interpretation of this Certificate of Designation
shall be governed by and construed and enforced in accordance with the internal laws of the State of Delaware, without regard to
the principles of conflict of laws thereof. Each party agrees that all legal proceedings concerning the interpretation, enforcement
and defense of the transactions contemplated by any of the Transaction Documents (whether brought against a party hereto or its
respective Affiliates, directors, officers, shareholders, employees or agents) shall be commenced in the state and federal courts
sitting in the City of New York, Borough of Manhattan (the "New York Courts"). Each party hereto hereby irrevocably
submits to the exclusive jurisdiction of the New York Courts for the adjudication of any dispute hereunder or in connection herewith
or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction
Documents), and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not
personally subject to the jurisdiction of such New York Courts, or such New York Courts are improper or inconvenient venue for
such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any such

of Designation or a waiver by any other Holders. The failure of the Corporation or a Holder to insist upon strict adherence to
any term of this Certificate of Designation on one or more occasions shall not be considered a waiver or deprive that party (or
any other Holder) of the right thereafter to insist upon strict adherence to that term or any other term of this Certificate of
Designation on any other occasion. Any waiver by the Corporation or a Holder must be in writing.


 


(f)          Severability.
