CITIGROUP INC., a Delaware
corporation (the “Company”, which term includes any successor Person under the Indenture), for value received, hereby
promises to pay to Cede & Co., or registered assigns, the principal sum of $___________ on January 14, 2022
and to pay interest thereon from and including July 14, 2012 or from the most recent Interest Payment Date to which interest
has been paid or duly provided for, semi-annually, on January 14 and July 14 of each year, commencing January 14, 2013 at the rate
of 4.500% per annum, until the principal hereof is paid or made available for payment. The interest so payable, and punctually
paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name
this Note is registered at the close of business on the Record Date for such interest, which shall be the January 2 and July 1
(whether or not a Business Day) immediately preceding each Interest Payment Date.

 

    	 

    	 

    

 

Any such interest not
so punctually paid or duly provided for will forthwith cease to be payable to the holder on such Record Date and may either be
paid to the Person in whose name this Note is registered at the close of business on a subsequent Record Date, such subsequent
Record Date to be not less than five days prior to the date of payment of such defaulted interest, notice whereof shall be given
to holders of Notes of this series not less than 15 days prior to such subsequent Record Date, or be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange on which the Notes of this series may be listed,
and upon such notice as may be required by such exchange, all as more fully provided in the Indenture.

 

Interest hereon will
be calculated on the basis of a 360-day year comprised of twelve 30-day months.

 

If either an Interest
Payment Date or the Maturity of the Notes falls on a day that is not a Business Day, such Interest Payment Date or Maturity will
be the next succeeding Business Day. If a date for payment of interest or principal on the Notes falls on a day that is not a business
day in the place of payment, such payment will be made on the next succeeding business day in such place of payment as if made
on the date the payment was due. No interest will accrue on any amounts payable for the period from and after the due date for
payment of such principal or interest.

 

For these purposes, “Business
Day” means any day which is a day on which commercial banks settle payments and are open for general business in The City
of New York.

 

Payment of the principal
of and interest on this Note will be made at the office or agency of the Trustee maintained for that purpose in The City of New
York.

 

Reference is hereby made
to the further provisions of this Note set forth on the reverse hereof, which further provisions shall for all purposes have the
same effect as if set forth at this place.

 

Unless the certificate
of authentication hereon has been executed by the Trustee or by an authenticating agent on behalf of the Trustee by manual signature,
this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

the Indenture, dated as of March 15, 1987 (as amended and supplemented to date, the “Indenture”), between the Company

as Trustee (the “Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and all

and immunities thereunder of the Company, the Trustee and the holders of the Notes and of the terms upon which the Notes are, and
are to be, authenticated and delivered. This Note is one of the series designated on the face hereof, initially issued in the aggregate

If an event of default
(as defined in the Indenture) with respect to Notes of this series shall occur and be continuing, the principal of the Notes of
this series may be declared due and payable in the manner and with the effect provided in the Indenture.

 

The Indenture contains
provisions for defeasance at any time of the entire indebtedness of this Note upon compliance by the Company with certain conditions
set forth in Sections 11.03 and 11.04 thereof, which provisions apply to this Note.

 

The Indenture contains

things, the form and terms of any series of Securities issuable thereunder by one or more supplemental indentures, and, with the
consent of the holders of not less than 66 2/3% in aggregate principal amount of Securities at the time outstanding which are affected
thereby, to modify the Indenture or any supplemental indenture or the rights of the holders of Securities of such series to be
affected, provided that no such modification will (i) extend the fixed maturity of any Securities, reduce the rate or extend the
time of payment of interest thereon, reduce the principal amount thereof or the premium, if any, thereon, reduce the amount of
the principal of Original Issue Discount Securities payable on any date, change the currency in which Securities are payable, or
impair the right to institute suit for the enforcement of any such payment on or after the maturity thereof, without the consent
of the holder of each Security so affected, or (ii) reduce the aforesaid percentage of Securities of any series the consent of
the holders of which is required for any such modification without the consent of the holders of all Securities of such series
then outstanding, or (iii) modify, without the written consent of the Trustee, the rights, duties or immunities of the Trustee.

currency, herein prescribed.

 

    	R-1

    	 

    

 

This Note is a Global
Security registered in the name of a nominee of the Depository. This Note is exchangeable for Notes registered in the name of a
person other than the Depository or its nominee only in the limited circumstances hereinafter described. Unless and until it is
exchanged in whole or in part for definitive Notes in certificated form, this Note may not be transferred except as a whole by
the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository.

 

The Notes represented
by this Global Security are exchangeable for definitive Notes in certificated form of like tenor as such Notes in denominations
of $1,000 and whole multiples of $1,000 in excess thereof only if (i) the Depository notifies the Company that it is unwilling
or unable to continue as Depository for the Notes or (ii) the Depository ceases to be a clearing agency registered under the Securities
Exchange Act of 1934, as amended, or (iii) the Company in its sole discretion decides to allow the Notes to be exchanged for definitive
Notes in registered form. Any Notes that are exchangeable pursuant to the preceding sentence are exchangeable for certificated
Notes issuable in authorized denominations and registered in such names as the Depository shall direct. As provided in the Indenture
and subject to certain limitations therein set forth, the transfer of definitive Notes in certificated form is registrable in the
register maintained by the Company in The City of New York for such purpose, upon surrender of the definitive Note for registration
of transfer at the office or agency of the registrar, duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the registrar duly executed by, the holder thereof or his attorney duly authorized in writing,
and thereupon one or more new Notes of this series and of like tenor, of authorized denominations and for the same aggregate principal
amount, will be issued to the designated transferee or transferees. Subject to the foregoing, this Note is not exchangeable, except
for a Global Security or Global Securities of this issue of the same principal amount to be registered in the name of the Depository
or its nominee.

 

No service charge shall
be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

 

Prior to due presentment
of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person
in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the
Company, the Trustee nor any such agent shall be affected by notice to the contrary.

 

The Company will pay
additional amounts (“Additional Amounts”) to the beneficial owner of any Note that is a non-United States person in
order to ensure that every net payment on such Note will not be less, due to payment of U.S. withholding tax, than the amount then
due and payable. For this purpose, a “net payment” on a Note means a payment by the Company or a paying agent, including
payment of principal and interest, after deduction for any present or future tax, assessment or other governmental charge of the
United States. These Additional Amounts will constitute additional interest on the Note.

 

The Company will not
be required to pay Additional Amounts, however, in any of the circumstances described in items (1) through (13) below.

 

    	R-2

    	 

    

 

 

		(1)	Additional Amounts will not be payable if a payment on a Note is reduced as a result of any tax,
assessment or other governmental charge that is imposed or withheld solely by reason of the beneficial owner:

 

	 	(a)	having a relationship with the United States as a citizen, resident or otherwise;
	 	(b)	having had such a relationship in the past or
	 	(c)	being considered as having had such a relationship.

 

		(2)	Additional Amounts will not be payable if a payment on a Note is reduced as a result of any tax,
assessment or other governmental charge that is imposed or withheld solely by reason of the beneficial owner:

 

	 	(a)	being treated as present in or engaged in a trade or business in the United States;
	 	(b)	being treated as having been present in or engaged in a trade or business in the United States in the past or
	 	(c)	having or having had a permanent establishment in the United States.

 

		(3)	Additional Amounts will not be payable if a payment on a Note is reduced as a result of any tax,
assessment or other governmental charge that is imposed or withheld in whole or in part by reason of the beneficial owner being
or having been any of the following (as such terms are defined in the Internal Revenue Code of 1986, as amended):

 

	 	(a)	personal holding company;
	 	(b)	foreign personal holding company;
	 	(c)	foreign private foundation or other foreign tax-exempt organization;
	 	(d)	passive foreign investment company;
	 	(e)	controlled foreign corporation or
	 	(f)	corporation which has accumulated earnings to avoid United States federal income tax.

 

		(4)	Additional Amounts will not be payable if a payment on a Note is reduced as a result of any tax,
assessment or other governmental charge that is imposed or withheld solely by reason of the beneficial owner owning or having owned,
actually or constructively, 10 percent or more of the total combined voting power of all classes of stock of the Company entitled
to vote or by reason of the beneficial owner being a bank that has invested in a Note as an extension of credit in the ordinary
course of its trade or business.

 

For purposes of items (1) through (4) above,
“beneficial owner” means a fiduciary, settlor, beneficiary, member or shareholder of the holder if the holder is an
estate, trust, partnership, limited liability company, corporation or other entity, or a person holding a power over an estate
or trust administered by a fiduciary holder.

 

    	R-3

    	 

    

 

 

		(5)	Additional Amounts will not be payable to any beneficial owner of a Note that is a:

 

	 	(a)	fiduciary;
	 	(b)	partnership;
	 	(c)	limited liability company or
		(d)	other fiscally transparent entity

 

or that is not the sole beneficial
owner of the Note, or any portion of the Note. However, this exception to the obligation to pay Additional Amounts will only apply
to the extent that a beneficiary or settlor in relation to the fiduciary, or a beneficial owner or member of the partnership, limited
liability company or other fiscally transparent entity, would not have been entitled to the payment of an Additional Amount had
the beneficiary, settlor, beneficial owner or member received directly its beneficial or distributive share of the payment.

 

		(6)	Additional Amounts will not be payable if a payment on a Note is reduced as a result of any tax,
assessment or other governmental charge that is imposed or withheld solely by reason of the failure of the beneficial owner or
any other person to comply with applicable certification, identification, documentation or other information reporting requirements.
This exception to the obligation to pay Additional Amounts will only apply if compliance with such reporting requirements is required
by statute or regulation of the United States or by an applicable income tax treaty to which the United States is a party as a
precondition to exemption from such tax, assessment or other governmental charge.

 

		(7)	Additional Amounts will not be payable if a payment on a Note is reduced as a result of any tax,
assessment or other governmental charge that is collected or imposed by any method other than by withholding from a payment on
a Note by the Company or a paying agent.

 

		(8)	Additional Amounts will not be payable if a payment on a Note is reduced as a result of any tax,
assessment or other governmental charge that is imposed or withheld by reason of a change in law, regulation, or administrative
or judicial interpretation that becomes effective more than 15 days after the payment becomes due or is duly provided for, whichever
occurs later.

 

		(9)	Additional Amounts will not be payable if a payment on a Note is reduced as a result of any tax,
assessment or other governmental charge that is imposed or withheld by reason of the presentation by the beneficial owner of a
Note for payment more than 30 days after the date on which such payment becomes due or is duly provided for, whichever occurs later.

   

		(10)	 Additional Amounts will not be payable if a payment on a Note is reduced as a result of any:

 

		

    	R-4

    	 

    

		

 

	 	(a)	estate tax;
	 	(b)	inheritance tax;
	 	(c)	gift tax;
	 	(d)	sales tax;
	 	(e)	excise tax;
	 	(f)	transfer tax;
	 	(g)	wealth tax;
	 	(h)	personal property tax or
		(i)	any similar tax, assessment, withholding, deduction or other governmental charge.

 

		(11)	Additional Amounts will not be payable if a payment on a Note is reduced as a result of any tax,
assessment, or other governmental charge required to be withheld by any paying agent from a payment of principal or interest on
a Note if such payment can be made without such withholding by any other paying agent.

 

		(12)	Additional amounts will not be payable if a payment on a Note is reduced as a result of any tax,
assessment or other governmental charge that is required to be made pursuant to any European Union directive on the taxation of
savings income or any law implementing or complying with, or introduced to conform to, any such directive.

 

		(13)	Additional Amounts will not be payable if a payment on a Note is reduced as a result of any combination
of items (1) through (12) above.

 

Except as specifically
provided herein, the Company will not be required to make any payment of any tax, assessment or other governmental charge imposed
by any government or a political subdivision or taxing authority of such government.

 

As used in this Note, “United States
person” means:

 

		(a)	any individual who is a citizen or resident of the United States;

		(b)	any corporation, partnership or other entity created or organized in or under the laws of the United States;

		(c)	any estate if the income of such estate falls within the federal income tax jurisdiction of the United States regardless of
the source of such income and

		(d)	any trust if a United States court is able to exercise primary supervision over its administration and one or more United States
persons have the authority to control all of the substantial decisions of the trust.

 

 Additionally, “non-United
States person” means a person who is not a United States person, and “United States” means the states of the
United States of America and the District of Columbia, but excluding its territories and its possessions.

 

    	R-5

    	 

    

 

Except as provided below, the Notes may
not be redeemed prior to maturity.

 

		(1)	The Company may, at its option, redeem the Notes if:

 

		(a)	the Company becomes or will become obligated to pay Additional Amounts as described above;

		(b)	the obligation to pay Additional Amounts arises as a result of any change in the laws, regulations
or rulings of the United States, or an official position regarding the application or interpretation of such laws, regulations
or rulings, which change is announced or becomes effective on or after October 25, 2011 and

		(c)	the Company determines, in its business judgment, that the obligation to pay such Additional Amounts
cannot be avoided by the use of reasonable measures available to it, other than substituting the obligor under the Notes or taking
any action that would entail a material cost to the Company.

 

		(2)	The Company may also redeem the Notes, at its option, if:

 

		(a)	any act is taken by a taxing authority of the United States on or after October 25, 2011, whether or not such act is taken
in relation to the Company or any affiliate, that results in a substantial probability that the Company will or may be required
to pay Additional Amounts as described above;

		(b)	the Company determines, in its business judgment, that the obligation to pay such Additional Amounts
cannot be avoided by the use of reasonable measures available to it, other than substituting the obligor under the Notes or taking
any action that would entail a material cost to the Company and

		(c)	the Company receives an opinion of independent counsel to the effect that an act taken by a taxing
authority of the United States results in a substantial probability that the Company will or may be required to pay the Additional
Amounts described under above, and delivers to the Trustee a certificate, signed by a duly authorized officer, stating that based
on such opinion the Company is entitled to redeem the Notes pursuant to their terms.

 

Any redemption of the Notes as set forth
in clauses (1) or (2) above shall be in whole, and not in part, and will be made at a redemption price equal to 100% of the principal
amount of the Notes Outstanding plus accrued interest thereon to the date of redemption. Holders shall be given not less than 30
days nor more than 60 days prior notice by the Trustee of the date fixed for such redemption.

 

All terms used in this Note which are defined
in the Indenture shall have the meanings assigned to them in the Indenture. The Notes are governed by the laws of the State of
New York.

I, Xiaojing Yu, hereby
certify that I am the Chairman of the Board and Chief Executive Officer of China Shen Zhou Mining & Resources, Inc. (the “Company”),
a corporation incorporated and existing under Chapter 78 of the Nevada Revised Statues (the “Nevada General Company Law”
or the “NGCL”) and further do hereby certify:

 

That pursuant to the
authority expressly conferred upon the Board of Directors of the Company (the “Board”) by the Company’s
Articles of Incorporation, as amended (the “Articles of Incorporation”) and the unanimous written consent of
the Holders (as defined below) pursuant to the Exchange Agreements (as defined below), the Board on August 7, 2012 adopted the
following resolutions amending and restating in their entirety the terms of a series of 10,000 shares of Preferred Stock designated
as Series A Convertible Preferred Stock, which were originally created on March 21, 2012, 3,333 of which shares are issued and
outstanding as of the date hereof:

 

RESOLVED, that the
Board designates the Series A Convertible Preferred Stock and the number of shares constituting such series, and fixes the rights,
powers, preferences, privileges and restrictions relating to such series in addition to any set forth in the Articles of Incorporation
as follows:

 

TERMS OF SERIES A CONVERTIBLE PREFERRED STOCK

 

1.     
Designation and Number of Shares. There shall hereby be created and established a series of preferred stock of the
Company designated as “Series A Convertible Preferred Stock” (the “Preferred Shares”). The authorized
number of Preferred Shares shall be 10,000 shares. Each Preferred Share shall have a par value of $0.001.
Capitalized terms not defined herein shall have the meaning as set forth in Section 27 below.

 

2.     
Ranking. Except to the extent that the holders of at least a majority of the outstanding Preferred Shares (the “Required
Holders”) expressly consent to the creation of Parity Stock (as defined below) or Senior Preferred Stock (as defined
below) in accordance with Section 17, all shares of capital stock of the Company shall be junior in rank to all Preferred Shares
with respect to the preferences as to dividends, distributions and payments upon the liquidation, dissolution and winding up of
the Company (such junior stock is referred to herein collectively as “Junior Stock”). The rights of all such
shares of capital stock of the Company shall be subject to the rights, powers, preferences and privileges of the Preferred Shares.
Without limiting any other provision of this Certificate of Designations, without the prior express consent of the Required Holders,
voting separate as a single class, the Company shall not hereafter authorize or issue any additional or other shares of capital
stock that is (i) of senior rank to the Preferred Shares in respect of the preferences as to dividends, distributions and payments
upon the liquidation, dissolution and winding up of the Company (collectively, the “Senior Preferred Stock”),
(ii) of pari passu rank to the Preferred Shares in respect of the preferences as to dividends, distributions and payments upon
the liquidation, dissolution and winding up of the Company (collectively, the “Parity Stock”) or (iii) any
Junior Stock having a maturity date (or any other date requiring redemption or repayment of such shares of Junior Stock) that
is prior to the Maturity Date. In the event of the merger or consolidation of the Company with or into another corporation, the
Preferred Shares shall maintain their relative rights, powers, designations, privileges and preferences provided for herein and
no such merger or consolidation shall result inconsistent therewith.

 

    	 

    	 

    
 

3.     
Dividends.

 

(a)      
From and after March 26, 2012 (the “Initial Issuance Date”), each holder of a Preferred Share (each,
a “Holder” and collectively, the “Holders”) shall be entitled to receive dividends (“Dividends”),
which Dividends shall be paid by the Company out of funds legally available therefor, payable, subject to the conditions and other
terms hereof, in shares of Common Stock or cash on the Stated Value (as defined below) of such Preferred Share, which Dividends
for the avoidance of doubt shall be calculated on such Preferred Shares without giving effect to any reduction for the payment
of any Installment Amount payable on such Dividend Date (as defined below), at the Dividend Rate (as defined below), which shall
be cumulative and shall continue to accrue and compound monthly whether or not declared and whether or not in any fiscal year there
shall be net profits or surplus available for the payment of dividends in such fiscal year. Dividends on the Preferred Shares shall
commence accumulating on the Initial Issuance Date and shall be computed on the basis of a 365-day year and actual days elapsed.
Dividends shall be payable quarterly in arrears on the first day of the applicable quarter (each, a
“Dividend Date”) with the first Dividend Date being July 1, 2012, and the last Dividend Date being the
Maturity Date. If a Dividend Date is not a Business Day (as defined below), then the Dividend shall be due and payable on the Business
Day immediately following such Dividend Date.

 

(b)              
Dividends shall be payable on each Dividend Date, to the record holders of the Preferred Shares on the applicable Dividend
Date, in shares of Common Stock (“Dividend Shares”) so long as there has been no Equity Conditions Failure
and so long as the delivery of Dividend Shares would not violate the provisions of Section 4(e); provided, however, that the Company
may, at its option, pay Dividends on any Dividend Date in cash (“Cash Dividends”) or in a combination of Cash
Dividends and, so long as there has been no Equity Conditions Failure, Dividend Shares. The Company shall deliver a written notice
(each, a “Dividend Election Notice”) to each Holder on the Dividend Notice Due Date (the date such notice is
delivered to all of the Holders, the “Dividend Notice Date”) which notice (1) either (A) confirms that Dividends
to be paid on such Dividend Date shall be paid entirely in Dividend Shares or (B) elects to pay Dividends as Cash Dividends or
a combination of Cash Dividends and Dividend Shares and specifies the amount of Dividends that shall be paid as Cash Dividends
and the amount of Dividends, if any, that shall be paid in Dividend Shares and (2) certifies that there has been no Equity Conditions
Failure as of such time, if any portion of the Dividends shall be paid in Dividend Shares. Notwithstanding anything herein to
the contrary, if no Equity Conditions Failure has occurred as of the Dividend Notice Date but an Equity Conditions Failure occurs
at any time prior to the Dividend Date, (A) the Company shall provide each Holder a subsequent notice to that effect and (B) unless
such Holder waives the Equity Conditions Failure, the Dividend payable to such Holder on such Dividend Date shall be paid in cash.
Dividends to be paid to each Holder on a Dividend Date in Dividend Shares shall be paid in a number of fully paid and non-assessable
shares (rounded to the nearest whole share) of Common Stock equal to the quotient of (1) the amount of Dividends payable to such
Holder on such Dividend Date less any Cash Dividends paid and (2) the Dividend Conversion Price in effect on the applicable Dividend
Date.

 

    	2

    	 

    
 

(c)               
When any Dividend Shares are to be paid on an Dividend Date to any Holder, the Company shall (i) (A) provided that the Company’s
transfer agent (the “Transfer Agent”) is participating in the Depository Trust Company (“DTC”)
Fast Automated Securities Transfer Program, credit such aggregate number of Dividend Shares to which such Holder shall be entitled
to such Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian system, or
(B) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver on the
applicable Dividend Date, to the address set forth in the register maintained by the Company for such purpose pursuant to the Securities
Purchase Agreement or to such address as specified by such Holder in writing to the Company at least two (2) Business Days prior
to the applicable Dividend Date, a certificate, registered in the name of such Holder or its designee, for the number of Dividend
Shares to which such Holder shall be entitled and (ii) with respect to each Dividend Date, pay to such Holder, in cash by wire
transfer of immediately available funds, the amount of any Cash Dividend. The Company shall pay any and all taxes that may be payable
with respect to the issuance and delivery of Dividend Shares.

 

4.     
Conversion. Each Preferred Share 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 4.

 

(a)                Holder’s
Conversion Right. Subject to the provisions of Section 4(e), at any time or times on or after the Initial Issuance Date,
each Holder shall be entitled to convert any whole number of Preferred Shares into validly issued, fully paid and
non-assessable shares of Common Stock in accordance with Section 4(c) at the Conversion Rate (as defined below).

 

(b)               Conversion
Rate. The number of validly issued, fully paid and non-assessable shares of Common Stock issuable upon conversion of each
Preferred Share pursuant to Section 4(a) shall be determined according to the following formula (the
“Conversion Rate”):

 

Conversion Amount

Conversion Price

 

No fractional
shares of Common Stock are to be issued upon the conversion of any Preferred Shares. 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.

 

    	3

    	 

    
 

(c)               
Mechanics of Conversion. The conversion of each Preferred Share shall be conducted in the following manner:

 

(i) Holder’s
Conversion. To convert a Preferred Share into validly issued, fully paid and non-assessable shares of Common Stock on any
date (a “Conversion Date”), a Holder shall 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 of the share(s) of Preferred Shares
subject to such conversion in the form attached hereto as Exhibit I (the “Conversion Notice”)
to the Company. If required by Section 4(c)(vi), within five (5) Trading Days following a conversion of any such Preferred Shares
as aforesaid, such Holder shall surrender to a nationally recognized overnight delivery service for delivery to the Company the
original certificates representing the share(s) of Preferred Shares (the “Preferred Share Certificates”) so
converted as aforesaid.

 

(ii)
Company’s Response. 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 such Holder and the Transfer Agent, which confirmation shall constitute
an instruction to the Transfer Agent to process such Conversion Notice in accordance with the terms herein. On or before the
second (2nd) Trading Day following the date of receipt by the Company of such Conversion Notice, the Company shall
(1) provided that the Transfer Agent is participating in DTC Fast Automated Securities Transfer Program, credit such
aggregate number of shares of Common Stock to which such Holder shall be entitled to such 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 such Conversion Notice, a certificate, registered in the name of such Holder or its designee,
for the number of shares of Common Stock to which such Holder shall be entitled. If the number of Preferred Shares
represented by the Preferred Share Certificate(s) submitted for conversion pursuant to Section 4(c)(vi) is greater than the
number of Preferred Shares being converted, then the Company shall if requested by such Holder, as soon as practicable and in
no event later than three (3) Trading Days after receipt of the Preferred Share Certificate(s) and at its own expense, issue
and deliver to such Holder (or its designee) a new Preferred Share Certificate representing the number of Preferred Shares
not converted.

 

(iii) Record
Holder. The Person or Persons entitled to receive the shares of Common Stock issuable upon a conversion of Preferred Shares
shall be treated for all purposes as the record holder or holders of such shares of Common Stock on the Conversion Date.

 

    	4

    	 

    
 

(iv) Company’s
Failure to Timely Convert. If the Company shall fail, for any reason or for no reason, to issue to a 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 such Holder is entitled and register
such shares of Common Stock on the Company’s share register or to credit such Holder’s or its designee’s balance
account with DTC for such number of shares of Common Stock to which such Holder is entitled upon such Holder’s conversion
of any Preferred Shares (as the case may be) (a “Conversion Failure”), then, in addition to all other remedies
available to such Holder, such Holder, upon written notice to the Company, may void its Conversion Notice with respect to, and
retain or have returned (as the case may be) any Preferred Shares that have not been converted pursuant to such Holder’s
Conversion Notice, provided that the voiding of a Conversion Notice shall not affect the Company’s obligations to make any
payments which have accrued prior to the date of such notice pursuant to the terms of this Certificate of Designations or otherwise.
In addition to the foregoing, if within three (3) Trading Days after the Company’s receipt of a Conversion Notice (whether
via facsimile or otherwise), the Company shall fail to issue and deliver a certificate to such Holder and register such shares
of Common Stock on the Company’s share register or credit such Holder’s or its designee’s balance account with
DTC for the number of shares of Common Stock to which such Holder is entitled upon such Holder’s conversion hereunder (as
the case may be), and if on or after such third (3rd) Trading Day such Holder (or any other Person in respect, or on
behalf, of such Holder) purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction
of a sale by such 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 such Holder so anticipated
receiving from the Company, then, in addition to all other remedies available to such Holder, the Company shall, within three (3)
Business Days after such Holder’s request and in such Holder’s discretion, either (i) pay cash to such Holder in an
amount equal to such 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 such Holder) (the “Buy-In Price”), at which point the Company’s obligation to so issue and deliver
such certificate or credit such Holder’s balance account with DTC for the number of shares of Common Stock to which such
Holder is entitled upon such 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 such Holder a certificate or certificates representing
such shares of Common Stock or credit such Holder’s balance account with DTC for the number of shares of Common Stock to
which such Holder is entitled upon such Holder’s conversion hereunder (as the case may be) and pay cash to such 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). Immediately following the voiding
of a Conversion Notice as aforesaid, the Conversion Price of any Preferred Shares returned or retained by such Holder for failure
to timely convert shall be adjusted to the lesser of (I) the Conversion Price relating to the voided Conversion Notice and (II)
the lowest Closing Bid Price of the Common Stock during the period beginning on the Conversion Date and ending on the date such
Holder voided the Conversion Notice, subject to further adjustment as provided in this Certificate of Designations.

(v) Pro
Rata Conversion; Disputes. In the event the Company receives a Conversion Notice from more than one Holder for the same Conversion
Date and the Company can convert some, but not all, of such Preferred Shares submitted for conversion, the Company shall convert
from each Holder electing to have Preferred Shares converted on such date a pro rata amount of such Holder’s Preferred Shares
submitted for conversion on such date based on the number of Preferred Shares submitted for conversion on such date by such Holder
relative to the aggregate number of Preferred Shares submitted for conversion on such date. In the event of a dispute as to the
number of shares of Common Stock issuable to a Holder in connection with a conversion of Preferred Shares, the Company shall issue
to such Holder the number of shares of Common Stock not in dispute and resolve such dispute in accordance with Section 26.

 

(vi) Book-Entry.
Notwithstanding anything to the contrary set forth in this Section 4, upon conversion of any Preferred Shares in accordance with
the terms hereof, no Holder thereof shall be required to physically surrender the certificate representing the Preferred Shares
to the Company following conversion thereof unless (A) the full or remaining number of Preferred Shares represented by the certificate
are being converted (in which event such certificate(s) shall be delivered to the Company as contemplated by this Section 4(c)(vi))
or (B) such Holder has provided the Company with prior written notice (which notice may be included in a Conversion Notice) requesting
reissuance of Preferred Shares upon physical surrender of any Preferred Shares. Each Holder and the Company shall maintain records
showing the number of Preferred Shares so converted by such Holder and the dates of such conversions or shall use such other method,
reasonably satisfactory to such Holder and the Company, so as not to require physical surrender of the certificate representing
the Preferred Shares upon each such conversion. In the event of any dispute or discrepancy, such records of such Holder establishing
the number of Preferred Shares to which the record holder is entitled shall be controlling and determinative in the absence of
manifest error. A Holder and any transferee or assignee, by acceptance of a certificate, acknowledge and agree that, by reason
of the provisions of this paragraph, following conversion of any Preferred Shares, the number of Preferred Shares represented
by such certificate may be less than the number of Preferred Shares stated on the face thereof. Each certificate for Preferred
Shares shall bear the following legend:

 

    	6

    	 

    
 

ANY TRANSFEREE OR ASSIGNEE
OF THIS CERTIFICATE SHOULD CAREFULLY REVIEW THE TERMS OF THE CORPORATION’S CERTIFICATE OF DESIGNATIONS RELATING TO THE
SHARES OF SERIES A PREFERRED STOCK REPRESENTED BY THIS CERTIFICATE, INCLUDING SECTION 4(c)(vi) THEREOF. THE NUMBER OF SHARES
OF SERIES A PREFERRED STOCK REPRESENTED BY THIS CERTIFICATE MAY BE LESS THAN THE NUMBER OF SHARES OF SERIES A PREFERRED STOCK
STATED ON THE FACE HEREOF PURSUANT TO SECTION 4(c)(vi) OF THE CERTIFICATE OF DESIGNATIONS RELATING TO THE SHARES OF SERIES A
PREFERRED STOCK REPRESENTED BY THIS CERTIFICATE.

 

(d)              
Taxes. The Company shall pay any and all documentary, stamp, transfer (but only in respect of the registered holder
thereof), issuance and other similar taxes that may be payable with respect to the issuance and delivery of shares of Common Stock
upon the conversion of Preferred Shares.

 

(e)               
Limitation on Beneficial Ownership.

 

(i)
Notwithstanding anything to the contrary contained in this Certificate of Designations, the Preferred Shares held by a Holder
shall not be convertible by such Holder, and the Company shall not effect any conversion of any Preferred Shares held by such
Holder (including, without limitation, pursuant to Section 8 hereof), to the extent (but only to the extent) that such Holder
or any of its affiliates would beneficially own in excess of 4.99% (the “Maximum Percentage”) of the
Common Stock. To the extent the above limitation applies, the determination of whether the Preferred Shares held by such
Holder shall be convertible (vis-à-vis other convertible, exercisable or exchangeable securities owned by such Holder
or any of its affiliates) and of which such securities shall be convertible, exercisable or exchangeable (as among all such
securities owned by such Holder and its affiliates) shall, subject to such Maximum Percentage limitation, be determined on
the basis of the first submission to the Company for conversion, exercise or exchange (as the case may be). No prior
inability of a Holder to convert Preferred Shares, or of the Company to issue shares of Common Stock to such Holder, pursuant
to this Section 4(e) shall have any effect on the applicability of the provisions of this Section 4(e) with respect to
any subsequent determination of convertibility or issuance (as the case may be). For purposes of this Section 4(e),
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 and the rules and regulations
promulgated thereunder. The provisions of this Section 4(e) shall be implemented in a manner otherwise than in strict
conformity with the terms of this Section 4(e) to correct this Section 4(e) (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 Section 4(e) shall apply to a successor holder of Preferred Shares. The holders of Common Stock shall be third party
beneficiaries of this Section 4(e) and the Company may not waive this Section 4(e) 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 a Holder, the Company shall
within one (1) Business Day confirm orally and in writing to such 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 Certificate of Designations or securities issued pursuant to the other
Transaction Documents. 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
such Holder sending such notice and not to any other Holder.

(ii)
Principal Market Regulation. The Company shall not issue any shares of Common Stock upon conversion of any Preferred Shares,
or otherwise pursuant to this Certificate of Designations, 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 Preferred
Shares or the Warrants or otherwise pursuant to this Certificate of Designations 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, 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 Required Holder. Until such approval or such written opinion
is obtained, no Holder shall be issued in the aggregate, upon exercise or conversion (as the case may be) of any Warrants or any
of the Preferred Shares or otherwise pursuant to this Certificate of Designations, 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 number of Preferred Shares issued
or issuable to such Buyer (as defined in the Securities Purchase Agreement) pursuant to the Securities Purchase Agreement on any
Closing Date (as defined in the Securities Purchase Agreement) divided by (2) the aggregate number of all Preferred Shares issued
or issuable to the Buyers pursuant to the Securities Purchase Agreement on any Closing Date (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 Preferred Shares,
the transferee shall be allocated a pro rata portion of such Buyer’s Exchange Cap Allocation with respect to such portion
of such Preferred Shares 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 exercise and conversion in full of a holder’s
Warrants and Preferred Shares or other issuance pursuant to this Certificate of Designations, 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 exercise in full of such Warrants and such holder’s conversion in full of such Preferred Shares shall be
allocated to the respective Exchange Cap Allocations of the remaining holders of Warrants and Preferred Shares on a pro rata basis
in proportion to the shares of Common Stock underlying the Warrants and Preferred Shares then held by each such holder. In the
event that the Company is prohibited from issuing all or any part of the shares of Common Stock issuable upon conversion of any
Preferred Shares (collectively, the “Exchange Cap Blocked Shares”) for which an Conversion Notice has been
received as a result of the operation of this Section 4(e)(ii), the Company shall pay cash to the holder of such Preferred Shares
in exchange for such Exchange Cap Blocked Shares on or prior to the applicable Share Delivery Deadline, at a price per Exchange
Cap Blocked Share equal to the difference between the Closing Sale Price of the Common Stock for the Trading Day immediately preceding
the date of the attempted conversion and the Conversion Price as of such date of attempted conversion.

(f)               
Mandatory Conversion.

  

(i)
General. At any time after the Initial Issuance Date the VWAP of the Common
Stock listed on the Principal Market exceeds $3.57 (as adjusted for stock splits, stock dividends, recapitalizations and
similar events) for twenty (20) consecutive Trading Days and there has been no Equity Conditions
Failure (a “Mandatory Conversion Eligibility Date”), the Company shall have the right to require each of
the Holders to convert the Conversion Amount of the Preferred Shares then outstanding into fully paid, validly issued and
nonassessable shares of Common Stock in accordance with Section 4(c) hereof at the Conversion Rate as of the Mandatory
Conversion Date (as defined below) (a “Mandatory Conversion”). The Company may exercise its right to
require conversion under this Section 4(f) by delivering a written notice thereof on such Mandatory Conversion
Eligibility Date by facsimile and overnight courier to all, but not less than all, of the Holders and the Transfer Agent (the “Mandatory
Conversion Notice” and the date all of the Holders received such notice by facsimile is referred to as the
“Mandatory Conversion Notice Date”). The Mandatory Conversion Notice shall be irrevocable. The Mandatory
Conversion Notice shall state (i) the Trading Day selected for the Mandatory Conversion in accordance with this Section 4(f),
which Trading Day shall be no earlier than ten (10) Trading Days and no later than twenty (20) Trading Days following the
Mandatory Conversion Notice Date (the “Mandatory Conversion Date”), (ii) the aggregate Conversion
Amount of the Preferred Shares subject to mandatory conversion from the Holders, in the aggregate, and each individual Holder
pursuant to this Section 4(f), (iii) the number of shares of Common Stock to be issued to each Holder on the
Mandatory Conversion Date and (iv) that there has been no Equity Conditions Failure; provided, however, that the Company may
not effect a Mandatory Conversion under this Section 4(f) in excess of the Holder Pro Rata Amount
of the applicable Mandatory Conversion Volume Limitation. Notwithstanding the foregoing, the Company may effect only one
(1) Mandatory Conversion during any twenty (20) consecutive Trading Days.

 

    	9

    	 

    
 

(ii)
Pro Rata Conversion Requirement. If the Company elects to cause a conversion of any Conversion
Amount of Preferred Shares pursuant to this Section 4(f), then it must simultaneously take the same action in the same proportion
with respect to all Holders of Preferred Shares. If the Company elects a Mandatory Conversion with respect to less than all of
the Conversion Amounts of the Preferred Shares then outstanding, then the Company shall require conversion of a Conversion Amount
from each of the Holders of Preferred Shares equal to the product of (i) the aggregate Conversion Amount of the Preferred
Shares which the Company has elected to cause to be converted pursuant to this Section 4(f), multiplied by (ii) the Holder Pro
Rata Amount (such fraction with respect to each Holder is referred to as its “Conversion Allocation Percentage”,
and such amount with respect to each Holder is referred to as its “Pro Rata Conversion Amount”); provided,
however, that in the event that any Holder’s Pro Rata Conversion Amount exceeds the outstanding Conversion Amount of such
Holder’s Preferred Shares then outstanding, then such excess Pro Rata Conversion Amount shall be allocated amongst the remaining
Holders of Preferred Shares in accordance with the foregoing formula. In the event that an initial Holder of any Preferred Shares
shall sell or otherwise transfer any of such Holder’s Preferred Shares, the transferee shall be allocated a pro rata portion
of such holder’s Conversion Allocation Percentage and the Pro Rata Conversion Amount.

 

5.                  Holder
Optional Redemption after Maturity Date. From and after the Maturity Date, any Holder may require the Company to redeem
(a “Maturity Redemption”) all or any number of Preferred Shares held by such Holder at a purchase price
equal to 100% of the Conversion Amount of such Preferred Shares (the “Maturity Redemption Price”)
by delivery of written notice thereof (the “Maturity Redemption Notice”) to the Company. The Maturity
Redemption Notice shall state the date the Company is required to pay to such Holder such Maturity Redemption Price (the
“Mandatory Redemption Date”), which date shall be no earlier than ten (10) Business Days following the
date of delivery of such Mandatory Redemption Notice. Redemptions required by this Section 5 shall be made in accordance with
the provisions of Section 7

.

6.                 
Triggering Event Redemptions.

 

(a)

Certificate of Designations or a request for exercise of any Warrants for shares of Common Stock in accordance with the provisions
of the Warrants;

 

(iv) at
any time following the tenth (10th) consecutive day (or, to the extent the Company has not breached any provision of
Section 12 hereof, the 120th consecutive day) that any Holder’s Authorized Share Allocation is less than the
number of shares of Common Stock that such Holder would be entitled to receive upon a conversion of all Preferred Shares held

or an indemnity and the Company or such Subsidiary (as the case may be) will receive the proceeds of such insurance or indemnity

    	13

    	 

    
 

(b)               Notice
of Triggering Event; Redemption Option Upon Triggering Event. Within two (2) Business Days after the Company becomes
aware that a Triggering Event has occurred, the Company shall deliver written notice thereof via facsimile and
overnight courier (with next day delivery specified) (“Notice of Triggering Event”) to each Holder. At any
time after the earlier of a Holder’s receipt of a Notice of Triggering Event and such Holder becoming aware of a
Triggering Event, such Holder shall have the right, at such Holder’s option, to require the Company to redeem up to all
of such Holder’s Preferred Shares by delivering written notice thereof via facsimile and overnight courier (with next
day delivery specified) (“Triggering Event Redemption Notice”) to the Company, which Triggering Event
Redemption Notice shall indicate the number of Preferred Shares that such Holder is electing to redeem. In addition to all
other rights of such Holder contained herein, each Preferred Share subject to redemption by the Company pursuant to this
Section 6(b)shall be redeemed by the Company at a price per Preferred Share equal to the greater of (i) the product of (A)
the Conversion Amount thereof multiplied by (B) the Triggering Event Redemption Premium and (ii) the product of (X) the
Conversion Rate then in effect with respect to the Conversion Amount thereof multiplied by (Y) the product of (1) the Equity
Value 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 Triggering Event and ending on the date the Company makes the entire
payment required to be made under this Section 6(b) (the “Triggering Event Redemption Price”).

 

(c)               
Payment of Redemption Price. Upon the Company’s receipt of the first Triggering Event Redemption Notice from
any Holder, the Company shall immediately notify each other Holder by facsimile of the Company’s receipt of such notice.
The Company shall deliver on the second (2nd) Business Day after the Company’s receipt of the first Triggering
Event Redemption Notice the applicable Triggering Event Redemption Price to all Holders that deliver a Triggering Event Redemption
Notice prior to the second (2nd) Business Day after the Company’s receipt of the first Triggering Event Redemption
Notice (the “Initial Triggering Event Redemption Date”). The Company shall deliver on the third (3rd)
Business Day after the Company’s receipt of a Triggering Event Redemption Notice the applicable Triggering Event Redemption
Price to a Holder who delivers a Triggering Event Redemption Notice at any time on or following the fourth (4th) Business
Day after the Company’s receipt of the first Triggering Event Redemption Notice (each, a “Subsequent Triggering
Event Redemption Date”, and together with the Initial Triggering Event Redemption Date, the “Triggering
Event Redemption Dates”). To the extent redemptions required by this Section 6 are deemed or determined by a court of
competent jurisdiction to be prepayments of the Preferred Shares by the Company, such redemptions shall be deemed to be voluntary
prepayments. Redemptions required by this Section 6 shall be made in accordance with the provisions of Section 7

.

7.     
Redemptions. 

 

(a)               
General. The Company shall deliver, as applicable, to each applicable
Holder in cash (i) the applicable Maturity Redemption on the applicable Maturity Redemption Date, (ii) the Company Redemption
Amount on the applicable Installment Date, (iii) if such Holder has submitted a Fundamental Transaction Redemption Notice in accordance
with Section 9(b), the applicable Fundamental Transaction Redemption Price on the Fundamental Transaction Redemption Date, (iv)
the applicable Alternate Company Redemption Price on the applicable Alternate Company Redemption Date and (iv) if such Holder
has submitted a Triggering Event Redemption Notice in accordance with Section 6(b), the applicable Triggering Event Redemption
Price to a Holder in cash on the applicable Triggering Event Redemption Date. In the event that the Company does not pay the applicable
Redemption Price to a Holder within the time period required, at any time thereafter and until the Company pays such unpaid Redemption
Price in full, such Holder shall have the option, in lieu of redemption, to require the Company to promptly return to such Holder
all or any portion of the Preferred Shares representing the Conversion Amount that was submitted for redemption and for which
the applicable Redemption Price has not been paid. 

 

    	14

    	 

    
 

(b)              
Pro Rata Redemptions. If the Company is unable to redeem all of the
Preferred Shares submitted in a redemption hereunder, the Company shall (i) redeem a pro rata amount from each Holder based on
the number of Preferred Shares submitted for redemption by such Holder relative to the total number of Preferred Shares submitted
for redemption by all Holders and (ii) in addition to any remedy any Holder may have under this Certificate of Designations and/or
any of the other Transaction Documents, pay to each Holder interest at the rate of 2% per month (prorated for partial months) in
respect of each unredeemed Preferred Share until paid in full. In the event of the Company’s redemption of any Preferred
Shares hereunder, a 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 such
Holder. Accordingly, any redemption premium due hereunder is intended by the parties to be, and shall be deemed, a reasonable estimate
of such Holder’s actual loss of its investment opportunity and not as a penalty.

 

(c)                Void
Redemption. In the event that the Company does not pay to a Holder the applicable Redemption Price within the time period
set forth in Section 7(a) for any reason (including, without limitation, to the extent such payment is prohibited pursuant to
Section 78.288 of the NGCL or otherwise pursuant to the NGCL), at any time thereafter and until the Company pays such unpaid
applicable Redemption Price in full, such Holder shall have the option to, in lieu of redemption, require the Company
to promptly return to such Holder any or all of the Preferred Shares that were submitted for redemption by such Holder under
this Section 7 and for which the applicable Redemption Price (together with any interest thereon) has not been paid, by
sending written notice thereof to the Company (whether via facsimile or otherwise) (the “Void Optional Redemption
Notice”). Upon the Company’s receipt of such Holder’s Void Optional Redemption Notice, (i) such
Holder’s Redemption Notice shall be null and void with respect to those Preferred Shares subject to such Void Optional
Redemption Notice, (ii) the Company shall immediately return to such Holder any Preferred Shares subject to such Void
Optional Redemption Notice and (iii) the Conversion Price with respect to each conversion effected thereafter by each Holder
shall be equal to the lowest of (A) the Conversion Price in effect on the applicable Conversion Date, (B) the Conversion
Price in effect on the date of the first Void Optional Redemption Notice, (C) 75% of the lowest Closing Bid Price of the
Common Stock during the period beginning on and including the date the first Redemption Notice is delivered to the Company
(or, with respect to a Company Redemption or Alternate Company Redemption, to the Holders) and ending on and including the
date on the first Void Optional Redemption Notice and (D) 75% of the VWAP of the Common Stock for the five (5) Trading Day
period immediately preceding the Conversion Date of the applicable conversion.

 

    	15

    	 

    
 

(d)               Disputes;
Miscellaneous. In the event of a dispute as to the determination of the arithmetic calculation of any Redemption Price,
such dispute shall be resolved pursuant to Section 26 with the term “Redemption Price” being substituted for the
term “Conversion Price.” A Holder’s delivery of a Void Optional Redemption Notice and exercise of
its rights following such notice shall not effect the Company’s obligations to make any payments which have accrued
prior to the date of such notice. In the event of a redemption hereunder of less than all of the Preferred Shares represented
by a particular Preferred Share Certificate, the Company shall promptly cause to be issued and delivered to such Holder of
such Preferred Shares a Preferred Share Certificate representing the remaining Preferred Shares which have not been redeemed,
if necessary.

 

8.     
Company Conversion or Company Redemption.

 

(a)               
General. On each applicable Installment Date, each Holder’s Installment Amount applicable to such Installment
Date shall be automatically converted in accordance with this Section 8 into shares of validly issued, fully paid and non-assessable
shares of Common Stock (a “Company Conversion”), provided that the Company may, at its option as described
below, in lieu of such Company Conversion redeem such Holder’s Installment Amount in cash (a “Company Redemption”)
subject to the provisions of this Section 8, provided further that, unless waived by the Required Holders, a Company Conversion
shall not occur with respect to such Holder’s Installment Amount and the Company shall instead be required to elect and
to redeem such Holder’s entire Installment Amount in cash pursuant to a Company Redemption if on the applicable Company
Installment Notice Due Date or on the applicable Installment Date (as the case may be) there is an Equity Conditions Failure.
On or prior to the date which is the thirty-third (33rd) Trading Day prior to each Installment Date (each, an “Company
Installment Notice Due Date”), with the first Company Installment Notice Due Date following the Amendment and Exchange
Date, August 1, 2012 (notwithstanding the foregoing, the Company shall be deemed to have delivered a Company Installment Notice
to each holder of Preferred Shares and elected a Company Conversion with respect to the Installment Amount related to such August
1, 2012 Company Installment Notice Due Date and the Holders shall be deemed to have waived any Price Failure or Volume Failure
in connection therewith), the Company shall deliver written notice (each, an “Company Installment Notice” and
the date all of the Holders receive such notice is referred to as to the “Company Installment Notice Date”),
to each Holder of Preferred Shares and such Company Installment Notice shall (i) either (A) confirm that such Holder’s Installment
Amount shall be automatically converted in whole pursuant to a Company Conversion or (B) state that the Company elects to redeem,
or is required to elect and redeem in accordance with the provisions of this Certificate of Designations, such Holder’s
Installment Amount in whole pursuant to a Company Redemption and (ii) if such Holder’s Installment Amount is to be converted
pursuant to a Company Conversion, certify that there is no Equity Conditions Failure as of the date of the Company Installment
Notice. Each Company Installment Notice shall be irrevocable by the Company and may not be revoked by the Company. If the Company
does not timely deliver a Company Installment Notice in accordance with this Section 8 (a) with respect to a particular Installment
Date, then the Company shall be deemed to have delivered an irrevocable Company Installment Notice confirming a Company Conversion
and shall be deemed to have certified that there is no Equity Conditions Failure on the applicable Company Installment Notice
Due Date and the applicable Installment Date. No later than two (2) Trading Days after delivery or deemed delivery (as applicable)
of the applicable Company Installment Notice confirming a Company Conversion, the Company shall deliver to such Holder’s
account with DTC such number of shares of Common Stock (the “Pre-Company Installment Shares”) equal to the
quotient of (x) the aggregate Stated Value of such Holder’s Installment Amount divided by (y) the Pre-Company Installment
Price, and as to which such Holder shall be the owner thereof as of such time of delivery or deemed delivery (as the case may
be) of such Company Installment Notice. If the Company elects a Company Redemption with respect to any Holder for an Installment
Date, then the Company must elect a Company Redemption with respect to all Holders for such Installment Date. A Company Conversion
(whether set forth in the Company Installment Notice or by operation of this Section 8 (a)) shall be converted in accordance with
Section 8(b) and a Company Redemption shall be redeemed in accordance with Section 8(c).

 

    	16

    	 

    
 

(b)               Mechanics
of Company Conversion. Subject to Section 8(a), if the Company delivers a Company Installment Notice and confirms, or is
deemed to have delivered a Company Installment Notice and is deemed to have confirmed, a Company Conversion in accordance
with Section 8(a), then the remainder of this Section 8(b) shall apply. With respect to each Holder, the aggregate Stated
Value of such Holder’s Installment Amount shall be automatically converted as of the applicable Installment Date on
such Installment Date at the Company Installment Price, and the Company shall, on the applicable Installment Date, deliver to
such Holder’s account with DTC such shares of Common Stock issued upon such Company Conversion (subject to the
reduction contemplated by the immediately following sentence and, if applicable, the last sentence of this Section 8(b)),
provided that there is no Equity Conditions Failure as of such Installment Date and a Company Conversion is not otherwise
prohibited under any other provision of this Certificate of Designations. The number of shares of Common Stock to be
delivered upon such Company Conversion shall be reduced by the amount of any Pre-Company Installment Shares delivered to such
Holder in connection with such Installment Date. If a Triggering Event occurs during any applicable Company Conversion
Measuring Period, then either (i) such Holder shall return any Pre-Company Installment Shares delivered in connection with
the applicable Installment Date or (ii) the Stated Value used to calculate the applicable Triggering Event Redemption Price
shall be reduced by the product of (x) the aggregate Stated Value of such Holder’s Installment Amount with respect to
such Installment Date multiplied by (y) the Conversion Share Ratio. If there is an Equity Conditions Failure as of such
Installment Date or a Company Conversion is not otherwise permitted under any other provision of this Certificate of
Designations, then, at the option of such Holder designated in writing to the Company, such Holder may require the Company to
do any one or more of the following: (i) the Company shall redeem all or any part designated by such Holder of the
unconverted Installment Amount (such designated amount is referred to as the “Designated
Redemption Amount”) and the Company shall pay to such Holder within three (3) days of such Installment Date, by
wire transfer of immediately available funds, an amount in cash equal to 125% of such Designated Redemption Amount, and/or
(ii) the applicable Company Conversion shall be null and void with respect to all or any part designated by such Holder of
the unconverted Installment Amount and such Holder shall be entitled to all the rights of a holder of Preferred Shares with
respect to such part of such with respect to such designated portion of the Installment Amount; provided, however, the
Conversion Price for such designated part of such unconverted Installment Amount shall thereafter be adjusted to equal the
lesser of (A) the Company Installment Price in effect on the date on which such Holder voided the Company Conversion and (B)
the Company Installment Price that would be in effect on the date on which such Holder delivers a Conversion Notice relating
thereto as if such date was an Installment Date. In addition, if there is an Equity Conditions Failure as of such Installment
Date or a Company Conversion is not otherwise permitted under any other provision of this Certificate of Designations, then,
at such Holder’s option, either (I) such Holder shall return any Pre-Company Installment Shares delivered in connection
with the applicable Installment Date or (II) the applicable Designated Redemption Amount shall be reduced by the product of
(X) the Installment Amount applicable to such automatic Conversion Date multiplied by (Y) the Conversion Share Ratio. If the
Company fails to redeem any Designated Redemption Amount by the third (3rd) day following the applicable
Installment Date by payment of such amount on the applicable Installment Date for any reason (including, without limitation,
to the extent such payment is prohibited pursuant to Section 78.288 of the NGCL or otherwise pursuant to the NGCL), then such
Holder shall have the rights set forth in Section 7 as if the Company failed to pay the applicable Company Redemption Price
and all other rights under this Certificate of Designations (including, without limitation, such failure constituting
a Triggering Event). Notwithstanding anything to the contrary in this Section 8(b), but subject to 4(e), until the Company
delivers Common Stock representing all of such Holder’s Installment Amount to such Holder pursuant to a Company
Conversion, such Holder’s Installment Amount may be converted by such Holder into Common Stock pursuant to Section 4.
In the event that a Holder elects to convert such Holder’s Installment Amount prior to the applicable Installment Date
as set forth in the immediately preceding sentence, the Installment 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. If,
with respect to an Installment Date, the number of Pre-Company Installment Shares delivered to a Holder exceeds the number of
Post-Company Installment Shares with respect to such Installment Date, then the number of shares of Common Stock equal to
such excess shall constitute a credit against the number of shares of Common Stock to be issued to such Holder pursuant to
Sections 4 and 8(b) hereof and shall reduce the number of shares of Common Stock required to be actually issued by the
Company to such Holder under such sections on a share-for-share basis until such time as the number of shares that would have
been issued by the Company to such Holder (not taking account of such credit) equals the amount of such excess.

 

    	17

    	 

    
 

(c)                Mechanics
of Company Redemption. If the Company elects, or is required to elect, a Company Redemption in accordance with Section
8(a), then each Holder’s Installment Amount shall be redeemed by the Company on the applicable Installment Date in an
amount of cash, and the Company shall pay to each such Holder on such Installment Date, by wire transfer of
immediately available funds, an amount equal to 100% of the aggregate Stated Value of such Holder’s Installment Amount
(the “Company Redemption Price”). If the Company fails to redeem a Holder’s Installment Amount on
the applicable Installment Date by payment of the Company Redemption Price on such date for any reason (including, without
limitation, to the extent such payment is prohibited pursuant to Section 78.288 of the NGCL or otherwise pursuant to the
NGCL), then, at the option of such Holder designated in writing to the Company (any such designation shall be a
“Conversion Notice” for purposes of this Certificate of Designations), such Holder may require the Company to
convert all or any part of such Holder’s Installment Amount at the Company Installment Price (determined as of the date
of such designation as if such date were an Installment Date). Conversions required by this Section 8(c)shall be made in
accordance with the provisions of Section 4(c). Notwithstanding anything to the contrary in this Section 8(c), but subject to
Section 4(e), until the Company Redemption Price is paid in full, such Holder’s Installment Amount may be converted, in
whole or in part, by such Holder into Common Stock pursuant to Section 4. In the event that a Holder elects to convert such
Holder’s Installment Amount prior to the applicable Installment Date as set forth in the immediately preceding
sentence, the Installment 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. Redemptions required by this Section 8(c) shall be made
in accordance with the provisions of Section 7

.

(d)               Deferred
Installments. Notwithstanding any provision of this Section 8 to the contrary, any Holder may, at its option and in its
sole discretion, deliver a written notice to the Company prior to the applicable Installment Date (the
“Amortization Notification Deadline Date”) electing to have the payment of all or any portion of the
Installment Amount to be converted or redeemed on such Installment Date deferred (such amount deferred, the
“Deferral Amount”) until any subsequent Installment Date selected by such
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 Dividends hereunder. Any notice delivered by such Holder
pursuant to this Section 8(d) shall set forth (x) the Deferral Amount and (y) the date that such Deferral Amount shall then
be payable.

 

(e)               
Company Redemption in lieu of Company Conversion. Notwithstanding anything herein to the contrary, on or prior to
the tenth (10th) Trading Day immediately prior to any Installment Date (such tenth (10th) Trading Day, the
“Alternate Company Redemption Date”), the Company may deliver written notice (an “Alternate Company
Redemption Notice”) to each Holder to elect to pay all additional shares of Common Stock issuable upon conversion of
such related Installment Amount in the related Company Conversion in cash (as determined as if the related Installment Date occurred
on the Alternate Company Redemption Date and the applicable Company Installment Price was equal to the applicable Alternate Installment
Price) (such number of shares of Common Stock payable with respect to each Preferred Share with respect thereto, the “Alternate
Per Share Amount”, and each such redemption, an “Alternate Company Redemption”) and upon payment
to each Holder of an amount in cash equal to the product of (x) the number of Preferred Shares held by the applicable Holder,
(y) the Alternate Per Share Amount and (z) the Alternate Installment Price (the “Alternate Company Redemption Price”),
by wire transfer of immediately available funds, the Company’s obligation to deliver any additional shares of Common Stock
to any Holder in connection with the related Company Conversion shall be deemed to be satisfied in full. If the Company fails
to effect the Alternate Company Redemption on the applicable Alternate Company Redemption Date by payment of the Alternate Company
Redemption Price on such date for any reason (including, without limitation, to the extent such payment is prohibited pursuant
to Section 78.288 of the NGCL or otherwise pursuant to the NGCL), then, such Alternate Company Redemption Notice shall be null
and void and the Company’s obligations to deliver additional shares of Common Stock on the applicable Installment Date in
connection with the applicable Company Conversion shall remain outstanding hereunder. Notwithstanding anything to the contrary
in this Section 8(e), but subject to Section 4(e), until the Alternate Company Redemption Price is paid in full, such Holder’s
Installment Amount may be converted, in whole or in part, by such Holder into Common Stock pursuant to Section 4. In the event
that a Holder elects to convert such Holder’s Installment Amount prior to the applicable Installment Date as set forth in
the immediately preceding sentence, the Installment 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. Redemptions required by this Section 8(e)
shall be made in accordance with the provisions of Section 7.

9.     
Rights Upon Fundamental Transactions.

 

(a)                Assumption.
The Company shall not enter into or be party to a Fundamental Transaction unless (i) the Successor Entity assumes in
writing all of the obligations of the Company under this Certificate of Designations and the other Transaction Documents in
accordance with the provisions of this Section 9(a) pursuant to written agreements in form and substance satisfactory to the
Required Holders and approved by the Required Holders prior to such Fundamental Transaction, including agreements to
deliver to each holder of Preferred Shares in exchange for such Preferred Shares a security of the Successor Entity evidenced
by a written instrument substantially similar in form and substance to this Certificate of Designations, including, without
limitation, having a stated value and dividend rate equal to the stated value and dividend rate of the Preferred Shares held
by the Holders and having similar ranking to the Preferred Shares, and reasonably satisfactory to the Required Holders and
(ii) the Successor Entity (including its Parent Entity) is a publicly traded corporation whose shares of common stock
are quoted on or listed for trading on an Eligible Market. 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 Certificate of Designations 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 Certificate of Designations and the other Transaction Documents with the same
effect as if such Successor Entity had been named as the Company herein and therein. In addition to the foregoing, upon
consummation of a Fundamental Transaction, the Successor Entity shall deliver to each Holder confirmation that there shall be
issued upon conversion or redemption of the Preferred Shares at any time after the consummation of such Fundamental
Transaction, in lieu of the shares of Common Stock (or other securities, cash, assets or other property (except such items
still issuable under Sections 10(a) and 16, which shall continue to be receivable thereafter)) issuable upon the
conversion or redemption of the Preferred Shares prior to such Fundamental Transaction, such shares of publicly traded common
stock (or their equivalent) of the Successor Entity (including its Parent Entity) which each Holder would have been entitled
to receive upon the happening of such Fundamental Transaction had all the Preferred Shares held by each Holder been converted
immediately prior to such Fundamental Transaction (without regard to any limitations on the conversion of the Preferred
Shares contained in this Certificate of Designations), as adjusted in accordance with the provisions of this Certificate of
Designations. The provisions of this Section 10 shall apply similarly and equally to successive Fundamental Transactions and
shall be applied without regard to any limitations on the conversion or redemption of the Preferred Shares.

 

    	19

    	 

    
 

(b)              
Fundamental Transaction Redemption Right. No sooner than twenty (20) Trading Days nor later than ten (10) Trading
Days prior to the consummation of a Fundamental Transaction, but not prior to the public announcement of such Fundamental Transaction,
the Company shall deliver written notice thereof via facsimile and overnight courier to each Holder (a “Fundamental Transaction
Notice”). At any time during the period beginning after a Holder’s receipt of a Fundamental Transaction Notice
or such Holder becoming aware of a Fundamental Transaction if a Fundamental Transaction Notice is not delivered to such Holder
in accordance with the immediately preceding sentence (as applicable) and ending on the later of twenty (20) Trading Days after
(A) consummation of such Fundamental Transaction or (B) the date of receipt of such Fundamental Transaction Notice, such Holder
may require the Company to redeem all or any portion of such Holder’s Preferred Shares by delivering written notice thereof
(“Fundamental Transaction Redemption Notice”) to the Company, which Fundamental Transaction Redemption Notice
shall indicate the number of Preferred Shares such Holder is electing to have the Company redeem. Each Preferred Share subject
to redemption pursuant to this Section 9(b) shall be redeemed by the Company in cash at a price equal to the greater of (i) the
product of the Fundamental Transaction Redemption Premium multiplied by the Conversion Amount thereof, (ii) the product of (X)
the Conversion Rate then in effect with respect to the Conversion Amount thereof multiplied by (Y) the product of (1) the Equity
Value 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 Fundamental Transaction and ending on the date the Company makes the entire
payment required to be made under this Section 9(b) and (iii) the product of (x) the Equity Value Redemption Premium and (y) the
product of (A) the Conversion Amount thereof multiplied by (B) the quotient determined by dividing (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 Fundamental Transaction (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 Fundamental Transaction, the Closing Sale Price of such securities on the Trading Day immediately following the public
announcement of such proposed Fundamental Transaction and the Closing Sale Price of such securities on the Trading Day immediately
prior to the public announcement of such proposed Fundamental Transaction) by (II) the Conversion Price then in effect (the “Fundamental
Transaction Redemption Price”). Redemptions required by this Section 9(b) shall have priority to payments to all other
stockholders of the Company in connection with such Fundamental Transaction. To the extent redemptions required by this Section
9(b) are deemed or determined by a court of competent jurisdiction to be prepayments of the Preferred Shares by the Company, such
redemptions shall be deemed to be voluntary prepayments. Notwithstanding anything to the contrary in this Section 9(b), but subject
to Section 4(e), until the applicable Fundamental Transaction Redemption Price is paid in full to the applicable Holder, the Preferred
Shares submitted by such Holder for redemption under this Section 9(b) may be converted, in whole or in part, by such Holder into
Common Stock pursuant to Section 4 or in the event the Conversion Date is after the consummation of such Fundamental Transaction,
stock or equity interests of the Successor Entity substantially equivalent to the Company’s shares of Common Stock pursuant
to Section 4. In the event of the Company’s redemption of any portion of the Preferred Shares under this Section 9(b), such
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 a Holder. Accordingly,
any redemption premium due under this Section 9(b) is intended by the parties to be, and shall be deemed, a reasonable estimate
of such Holder’s actual loss of its investment opportunity and not as a penalty. The Company shall make payment of the applicable
Fundamental Transaction Redemption Price concurrently with the consummation of such Fundamental Transaction if a Fundamental Transaction
Redemption Notice is received prior to the consummation of such Fundamental Transaction and within two (2) Trading Days after
the Company’s receipt of such notice otherwise (the “Fundamental Transaction Redemption Date”). Redemptions
required by this Section 9 shall be made in accordance with the provisions of Section 7.

 

    	20

    	 

    
 

10.             
Rights Upon Issuance of Purchase Rights and Other Corporate Events.

 

(a)                Purchase
Rights. In addition to any adjustments pursuant to Section 11 below, if at any time the Company grants, issues or sells
any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the
record holders of any class of Common Stock (the “Purchase Rights”), then each Holder will be entitled to
acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which such Holder could have
acquired if such Holder had held the number of shares of Common Stock acquirable upon complete conversion of all the
Preferred Shares (without taking into account any limitations or restrictions on the convertibility of the Preferred Shares)
held by such Holder 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 Common Stock are to be determined for the
grant, issue or sale of such Purchase Rights (provided, however, to the extent that such Holder’s right to participate
in any such Purchase Right would result in such Holder exceeding the Maximum Percentage, then such 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 such
Holder until such time, if ever, as its right thereto would not result in such Holder exceeding the Maximum Percentage).

 

    	21

    	 

    
 

(b)               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 each Holder will thereafter have the right to receive upon a conversion of
all the Preferred Shares held by such Holder (i) in addition to the shares of Common Stock receivable upon such conversion,
such securities or other assets to which such Holder would have been entitled with respect to such shares of Common Stock had
such shares of Common Stock been held by such Holder upon the consummation of such Corporate Event (without taking into
account any limitations or restrictions on the convertibility of the Preferred Shares contained in this Certificate of
Designations) or (ii) 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 such Holder would have been entitled to receive had the Preferred Shares held by such Holder 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. The provisions of this Section 10 shall apply similarly and
equally to successive Corporate Events and shall be applied without regard to any limitations on the conversion or redemption
of the Preferred Shares contained in this Certificate of Designations.

 

11.             
Rights Upon Issuance of Other Securities.

 

(a)               
Adjustment of Conversion Price upon Issuance of Common Stock. If
and whenever on or after the Subscription Date the Company issues or sells, or in accordance with this Section 11(a) is
deemed to have issued or sold, any shares of Common Stock (including the issuance or sale of shares of Common Stock owned or held
by or for the account of the Company, but excluding any Excluded Securities issued or sold or deemed to have been issued or sold)
for a consideration per share (the “New Issuance Price”) less than a price equal to the Conversion Price in
effect immediately prior to such issue or sale or deemed issuance or sale (such Conversion Price then in effect is referred to
herein as the “Applicable Price”) (the foregoing a “Dilutive Issuance”), then, immediately
after such Dilutive Issuance, the Conversion Price then in effect shall be reduced to an amount equal to the New Issuance Price.
For all purposes of the foregoing (including, without limitation, determining the adjusted Conversion Price and consideration
per share under this Section 11(a)), the following shall be applicable:

 

    	22

    	 

    
 

(i)
Issuance of Options. If the Company in any manner grants or sells any Options and the lowest price per share for which
one share of Common Stock is issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible
Securities issuable upon exercise of any such Option is less than the Applicable Price, then such share of Common Stock shall
be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option
for such price per share. For purposes of this Section 11(a)(i), the “lowest price per share for which one share of Common
Stock is issuable upon the exercise of any such Options or upon conversion, exercise or exchange of any Convertible Securities
issuable upon exercise of any such Option” shall be equal to (1) the lower of (x) the sum of the lowest amounts of consideration
(if any) received or receivable by the Company with respect to any one share of Common Stock upon the granting or sale of such
Option, upon exercise of such Option and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise
of such Option and (y) the lowest exercise price set forth in such Option for which one share of Common Stock is issuable upon
the exercise of any such Options or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise
of any such Option minus (2) the sum of all amounts paid or payable to the holder of such Option (or any other Person) upon the
granting or sale of such Option, upon exercise of such Option and upon conversion, exercise or exchange of any Convertible Security
issuable upon exercise of such Option plus the value of any other consideration received or receivable by, or benefit conferred
on, the holder of such Option (or any other Person). Except as contemplated below, no further adjustment of the Conversion Price
shall be made upon the actual issuance of such share of Common Stock or of such Convertible Securities upon the exercise of such
Options or upon the actual issuance of such share of Common Stock upon conversion, exercise or exchange of such Convertible Securities.

 

(ii)
Issuance of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the
lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof is less
than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold
by the Company at the time of the issuance or sale of such Convertible Securities for such price per share. For purposes of this
Section 11(a)(ii), the “lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise
or exchange thereof” shall be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if any) received
or receivable by the Company with respect to one share of Common Stock upon the issuance or sale of the Convertible Security and
upon conversion, exercise or exchange of such Convertible Security and (y) the lowest conversion price set forth in such Convertible
Security for which one share of Common Stock is issuable upon conversion, exercise or exchange thereof minus (2) the sum of all
amounts paid or payable to the holder of such Convertible Security (or any other Person) upon the issuance or sale of such Convertible
Security plus the value of any other consideration received or receivable by, or benefit conferred on, the holder of such Convertible
Security (or any other Person). Except as contemplated below, no further adjustment of the Conversion Price shall be made upon
the actual issuance of such share of Common Stock upon conversion, exercise or exchange of such Convertible Securities, and if
any such issue or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of the Conversion
Price has been or is to be made pursuant to other provisions of this Section 11(a), except as contemplated below, no further adjustment
of the Conversion Price shall be made by reason of such issue or sale.

(iii)
Change in Option Price or Rate of Conversion. If the purchase or exercise price provided for in any Options, the additional
consideration, if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at
which any Convertible Securities are convertible into or exercisable or exchangeable for shares of Common Stock increases or decreases
at any time, the Conversion Price in effect at the time of such increase or decrease shall be adjusted to the Conversion Price
which would have been in effect at such time had such Options or Convertible Securities provided for such increased or decreased
purchase price, additional consideration or increased or decreased conversion rate (as the case may be) at the time initially
granted, issued or sold. For purposes of this Section 11(a)(iii), if the terms of any Option or Convertible Security that was
outstanding as of the Subscription Date are increased or decreased in the manner described in the immediately preceding sentence,
then such Option or Convertible Security and the shares of Common Stock deemed issuable upon exercise, conversion or exchange
thereof shall be deemed to have been issued as of the date of such increase or decrease. No adjustment pursuant to this Section
11(a) shall be made if such adjustment would result in an increase of the Conversion Price then in effect.

 

(iv)
Calculation of Consideration Received. If any Option or Convertible Security or Adjustment Right is issued or deemed
issued in connection with the issuance or sale or deemed issuance or sale of any other securities of the Company, together comprising
one integrated transaction, (x) such Option or Convertible Security (as applicable) or Adjustment Right will be deemed to have
been issued for consideration equal to the Black Scholes Consideration Value thereof and (y) the other securities issued or sold
or deemed to have been issued or sold in such integrated transaction shall be deemed to have been issued for consideration equal
to the difference of (I) the aggregate consideration received or receivable by the Company minus (II) the Black Scholes Consideration
Value of each such Option or Convertible Security (as applicable) or Adjustment Right. If any shares of Common Stock, Options or
Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will
be deemed to be the net amount of consideration received by the Company therefor. If any shares of Common Stock, Options or Convertible
Securities are issued or sold for a consideration other than cash, the amount of such consideration received by the Company will
be the fair value of such consideration, except where such consideration consists of publicly traded securities, in which case
the amount of consideration received by the Company for such securities will be the average VWAP of such security for the five
(5) Trading Day period immediately preceding the date of receipt. If any shares of Common Stock, Options or Convertible Securities
are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity,
the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the
non-surviving entity as is attributable to such shares of Common Stock, Options or Convertible Securities (as the case may be).
The fair value of any consideration other than cash or publicly traded securities will be determined jointly by the Company and
the Required Holders. If such parties are unable to reach agreement within ten (10) days after the occurrence of an event requiring
valuation (the “Valuation Event”), the fair value of such consideration will be determined within five (5) Trading
Days after the tenth (10th) day following such Valuation Event by an independent, reputable appraiser jointly selected
by the Company and the Required Holders. The determination of such appraiser shall be final and binding upon all parties absent
manifest error and the fees and expenses of such appraiser shall be borne by the Company.

 

    	24

    	 

    
 

(v)
Record Date. If the Company takes a record of the holders of shares of Common Stock for the purpose of entitling them
(A) to receive a dividend or other distribution payable in shares of Common Stock, Options or in Convertible Securities or (B)
to subscribe for or purchase shares of Common Stock, Options or Convertible Securities, then such record date will be deemed to
be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such
dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase (as the
case may be).

 

(b)               Adjustment
of Conversion Price upon Subdivision or Combination of Common Stock. Without
limiting any provision of Section 9 or Section 11(a), 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 9 or Section 11(a),
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 11(b) shall
become effective immediately after the effective date of such subdivision or combination. If any event requiring an
adjustment under this Section 11(b) 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.

 

(c)               
Holder’s Right of Alternative Conversion Price Following Issuance of Certain Options or Convertible Securities.
In addition to and not in limitation of the other provisions of this Section 11(c), if the Company in any manner issues or sells
any Options or Convertible Securities (any such securities, “Variable Price Securities”) after the Subscription
Date that are convertible into or exchangeable or exercisable for shares of Common Stock 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 each Holder on the date of issuance of
such Convertible Securities or Options. From and after the date the Company issues any such Convertible Securities or Options
with a Variable Price, each 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 the Preferred Shares by designating in the Conversion Notice delivered upon
any conversion of Preferred Shares that solely for purposes of such conversion such Holder is relying on the Variable Price rather
than the Conversion Price then in effect. A Holder’s election to rely on a Variable Price for a particular conversion of
Preferred Shares shall not obligate such Holder to rely on a Variable Price for any future conversions of Preferred Shares.

 

    	25

    	 

    
 

(d)               Stock
Combination Event Adjustment. If at any time and from time to time on or after
the Issuance Date there occurs any stock split, stock dividend, stock combination recapitalization or other similar
transaction involving the Common Stock (each, a “Stock Combination Event”) and the product of (i)
the quotient determined by dividing (x) the Conversion Price in effect immediately prior to the Stock Combination Event by
(y) the quotient determined by dividing (A) the sum of the VWAP of the Common Stock on each day of the fifteen (15) Trading
Day period immediately prior to the Stock Combination Event, divided by (B) fifteen (15); and (ii) the quotient determined by
dividing (x) the sum of the VWAP of the Common Stock on each day of the fifteen (15) Trading Day period immediately following
the date of such Stock Combination Event, divided by (y) fifteen (15) (each, an “Event Market Price”) is
less than the Conversion Price then in effect (after giving effect to the adjustment in Section 11(b) above), then on the
sixteenth (16th) Trading Day immediately following such Stock Combination Event, the Conversion Price then in effect on such
sixteenth (16th) Trading Day (after giving effect to the adjustment in Section 11(b) above) shall be reduced (but in
no event increased) to the Event Market Price. For the avoidance of doubt, if the adjustment in the immediately preceding
sentence would otherwise result in an increase in the Conversion Price hereunder, no adjustment shall be made.

 

(e)               
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
any Holder from dilution or if any event occurs of the type contemplated by the provisions of this Section 11 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 Board shall in good faith determine and implement an appropriate adjustment in
the Conversion Price so as to protect the rights of such Holder, provided that no such adjustment pursuant to this Section 11(c)
will increase the Conversion Price as otherwise determined pursuant to this Section 11, provided further that if such Holder does
not accept such adjustments as appropriately protecting its interests hereunder against such dilution, then the Board and such
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.

 

    	26

    	 

    
 

(f)                Calculations.
All calculations under this Section 11 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.

 

12.             
Authorized Shares.

 

(a)               
Reservation. The Company shall initially reserve out of its authorized and unissued Common Stock a number of shares
of Common Stock equal to the sum of (i) 125% of the Conversion Rate with respect to the Conversion Amount of each Preferred Share
as of the Initial Issuance Date (assuming for purposes hereof, that all the Preferred Shares issuable pursuant to the Securities
Purchase Agreement have been issued, such Preferred Shares are convertible at the Conversion Price and without taking into account
any limitations on the conversion of such Preferred Shares set forth in herein) and (ii) the maximum number of Dividend Shares
issuable pursuant to the terms of this Certificate of Designations from the Initial Issuance Date through the Maturity Date (assuming
for purposes hereof, that all the Preferred Shares issuable pursuant to the Securities Purchase Agreement have been issued and
without taking into account any limitations on the issuance of securities set forth herein). So long as any of the Preferred Shares
are outstanding, the Company shall take all action 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 Preferred Shares, the sum of (i) 125% of the number
of shares of Common Stock as shall from time to time be necessary to effect the conversion of all of the Preferred Shares issued
or issuable pursuant to the Securities Purchase Agreement and (ii) the maximum number of Dividend Shares issuable pursuant to the
terms of this Certificate of Designations from such date through the Maturity Date assuming for purposes hereof, that all the Preferred
Shares issuable pursuant to the Securities Purchase Agreement have been issued and without taking into account any limitations
on the issuance of securities set forth herein), provided that at no time shall the number of shares of Common Stock so available
be less than the number of shares required to be reserved by the previous sentence (without regard to any limitations on conversions
contained in this Certificate of Designations) (the “Required Amount”). The initial number of shares of Common
Stock reserved for conversions of the Preferred Shares and for issuance as Dividend Shares and each increase in the number of shares
so reserved shall be allocated pro rata among the Holders based on the number of Preferred Shares held by each Holder on the Initial
Issuance Date or increase in the number of reserved shares (as the case may be) (the “Authorized Share Allocation”).
In the event a Holder shall sell or otherwise transfer any of such Holder’s Preferred Shares, 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 Preferred Shares shall be allocated to the remaining Holders of Preferred Shares, pro rata based
on the number of Preferred Shares then held by such Holders.

 

    	27

    	 

    
 

(b)               Insufficient
Authorized Shares. If, notwithstanding Section 12(a) and not in limitation thereof, at any time while any of the
Preferred Shares remain outstanding the Company does not have a sufficient number of authorized and unissued shares of Common
Stock to satisfy its obligation to have available for issuance upon conversion of the Preferred Shares at least a number of
shares of Common Stock equal to the Required Amount (an “Authorized Share Failure”), then the Company
shall immediately take all action necessary to increase the Company’s authorized shares of Common Stock to an amount
sufficient to allow the Company to reserve and have available the Required Amount for all of the Preferred Shares 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 best efforts to solicit its stockholders’ approval of such increase in authorized
shares of Common Stock and to cause its Board to recommend to the stockholders that they approve such proposal. Nothing
contained in this Section 12 shall limit any obligations of the Company under any provision of the Securities Purchase
Agreement. In the event that the Company is prohibited from issuing shares of Common Stock upon a conversion of any Preferred
Share 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 such Holder of such Preferred Shares,
the Company shall pay cash in exchange for the cancellation of such Preferred Shares convertible into such Authorized Failure
Shares at a price equal to the sum of (i) the product of (x) such number of Authorization Failure Shares and (y) the Closing
Sale Price on the Trading Day immediately preceding the date such Holder delivers the applicable Conversion Notice with
respect to such Authorization Failure Shares to the Company and (ii) to the extent such Holder purchases (in an open market
transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by such Holder of Authorization Failure
Shares, any brokerage commissions and other out-of-pocket expenses, if any, of such Holder incurred in connection
therewith.

 

13.             
Covenants.

 

(a)               
Incurrence of Indebtedness. The Company shall not, and the Company
shall cause each of its Subsidiaries to not, directly or indirectly, incur or guarantee, assume or suffer to exist any Indebtedness
(other than Permitted Indebtedness).

 

(b)              
Existence of Liens. The Company shall not, and the Company shall
cause each of its Subsidiaries to not, directly or indirectly, allow or suffer to exist any mortgage, lien, pledge, charge, security
interest or other encumbrance upon or in any property or assets (including accounts and contract rights) owned by the Company or
any of its Subsidiaries (collectively, “Liens”) other than Permitted Liens.

 

    	28

    	 

    
 

(c)               
Restricted Payments. The Company shall not, and the Company shall
cause each of its Subsidiaries to not, directly or indirectly, redeem, defease, repurchase, repay or make any payments in respect
of, by the payment of cash or cash equivalents (in whole or in part, whether by way of open market purchases, tender offers, private
transactions or otherwise), all or any portion of any Indebtedness, whether by way of payment in respect of principal of (or premium,
if any) or interest on, such Indebtedness if at the time such payment is due or is otherwise made or, after giving effect to such
payment, (i) an event constituting a Triggering Event has occurred and is continuing or (ii) an event that with the passage of
time and without being cured would constitute a Triggering Event has occurred and is continuing.

 

(d)              
Restriction on Redemption and Cash Dividends. Except with respect
to the payment of Dividends hereunder, the Company shall not, and the Company shall cause each of its Subsidiaries to not, directly
or indirectly, redeem, repurchase or declare or pay any cash dividend or distribution on any of its capital stock.

 

(e)               
Restriction on Transfer of Assets. The Company shall not, and the
Company shall cause each of its Subsidiaries to not, directly or indirectly, sell, lease, license, assign, transfer, spin-off,
split-off, close, convey or otherwise dispose of any assets or rights of the Company or any Subsidiary owned or hereafter acquired
whether in a single transaction or a series of related transactions, other than (i) sales, leases, licenses, assignments, transfers,
conveyances and other dispositions of such assets or rights by the Company and its Subsidiaries that, in the aggregate, do not
have a fair market value in excess of $2,000,000 in any twelve (12) month period and (ii) sales of inventory in the ordinary course
of business.

 

(f)               
Maturity of Indebtedness. The Company shall not, and the Company
shall cause each of its Subsidiaries to not, directly or indirectly, permit any Indebtedness of the Company or any of the Subsidiaries
to mature or accelerate prior to the Maturity Date.

 

(g)              
Change in Nature of Business. The Company shall not, and the Company
shall cause each of its Subsidiaries to not, directly or indirectly, engage in any material line of business substantially different
from those lines of business conducted by the Company and each of its Subsidiaries on the Initial Issuance Date or any business
substantially related or incidental thereto. The Company shall not, and the Company shall cause each of its Subsidiaries to not,
directly or indirectly, modify its or their corporate structure or purpose. For the purposes of this section, but without limiting
what is construed as the nature of the Company’s business, if the Company engages in other types of mining of processing
related thereto or industries downstream from the materials that the Company mines or produces shall not be considered a change
in the nature of the business of the Company.

 

(h)              
Preservation of Existence, Etc. The Company shall maintain and preserve,
and cause each of its Subsidiaries to maintain and preserve, its existence, rights and privileges to the extent necessary to carry-on
in the ordinary course of business, and become or remain, and cause each of its Subsidiaries to become or remain, duly qualified
and in good standing in each jurisdiction in which the character of the properties owned or leased by it or in which the transaction
of its business makes such qualification necessary.

 

    	29

    	 

    
 

(i)                
Maintenance of Properties, Etc. The Company shall maintain and preserve,
and cause each of its Subsidiaries to maintain and preserve, all of its properties which are necessary or useful in the proper
conduct of its business in good working order and condition, ordinary wear and tear excepted, and comply, and cause each of its
Subsidiaries to comply, at all times with the provisions of all leases to which it is a party as lessee or under which it occupies
property, so as to prevent any loss or forfeiture thereof or thereunder.

 

(j)                
Maintenance of Insurance. The Company shall maintain, and cause each
of its Subsidiaries to maintain, insurance with responsible and reputable insurance companies or associations (including, without
limitation, comprehensive general liability, hazard, rent and business interruption insurance) with respect to its properties (including
all real properties leased or owned by it) and business, in such amounts and covering such risks as is required by any governmental
authority having jurisdiction with respect thereto or as is carried generally in accordance with sound business practice by companies
in similar businesses similarly situated.

 

14.              Voting
Rights. Holders of Preferred Shares shall have no voting rights, except as required by law (including without limitation,
the NGCL) and as expressly provided in this Certificate of Designations. To the extent that under the NGCL the vote of the
holders of the Preferred Shares, voting separately as a class or series as applicable, is required to authorize a
given action of the Company, the affirmative vote or consent of the holders of all of the shares of the Preferred Shares,
voting together in the aggregate and not in separate series unless required under the NGCL, represented at a duly held
meeting at which a quorum is presented or by written consent of all of the Preferred Shares (except as otherwise may be
required under the NGCL), voting together in the aggregate and not in separate series unless required under the NGCL, shall
constitute the approval of such action by both the class or the series, as applicable. Subject to Section 4(e), to the extent
that under the NGCL holders of the Preferred Shares are entitled to vote on a matter with holders of shares of Common Stock,
voting together as one class, each Preferred Share shall entitle the holder thereof to cast that number of votes per share as
is equal to the number of shares of Common Stock into which it is then convertible (subject to the ownership limitations
specified in Section 4(e) hereof) using the record date for determining the stockholders of the Company eligible to vote on
such matters as the date as of which the Conversion Price is calculated. Holders of the Preferred Shares shall be entitled to
written notice of all stockholder meetings or written consents (and copies of proxy materials and other information sent to
stockholders) with respect to which they would be entitled by vote, which notice would be provided pursuant to the
Company’s bylaws and the NGCL).

 

    	30

    	 

    
 

15.             
Liquidation, Dissolution, Winding-Up. In the event of a Liquidation Event, the Holders shall be entitled to receive
in cash out of the assets of the Company, whether from capital or from earnings available for distribution to its stockholders
(the “Liquidation Funds”), before any amount shall be paid to the holders of any of shares of Junior Stock,
an amount per Preferred Share equal to the sum of (i) the Black Scholes Value (as defined in the Warrants) with respect to the
outstanding portion of all Warrants held by such Holder (without regard to any limitations on the exercise thereof) as of the
date of such event and (ii) the greater of (A) 120% of the Conversion Amount thereof on the date of such payment and (B) the amount
per share such Holder would receive if such Holder converted such Preferred Shares into Common Stock immediately prior to the
date of such payment, provided that if the Liquidation Funds are insufficient to pay the full amount due to the Holders and holders
of shares of Parity Stock, then each Holder and each holder of Parity Stock shall receive a percentage of the Liquidation Funds
equal to the full amount of Liquidation Funds payable to such Holder and such holder of Parity Stock as a liquidation preference,
in accordance with their respective certificate of designations (or equivalent), as a percentage of the full amount of Liquidation
Funds payable to all holders of Preferred Shares and all holders of shares of Parity Stock. To the extent necessary, the Company
shall cause such actions to be taken by each of its Subsidiaries so as to enable, to the maximum extent permitted by law, the
proceeds of a Liquidation Event to be distributed to the Holders in accordance with this Section 15. All the preferential amounts
to be paid to the Holders under this Section 15 shall be paid or set apart for payment before the payment or setting apart for
payment of any amount for, or the distribution of any Liquidation Funds of the Company to the holders of shares of Junior Stock
in connection with a Liquidation Event as to which this Section 15 applies. Upon payment in full of the Black-Scholes Value of
such Warrants pursuant to this Section 15, such Warrants shall be deemed repurchased by the Company and no longer exercisable.

 

16.             
Participation. In addition to any adjustments pursuant to Section 11, the Holders shall, as holders of Preferred
Shares, be entitled to receive such dividends paid and distributions made to the holders of shares of Common Stock to the same
extent as if such Holders had converted each Preferred Share held by each of them into shares of Common Stock (without regard
to any limitations on conversion herein or elsewhere) and had held such shares of Common Stock on the record date for such dividends
and distributions. Payments under the preceding sentence shall be made concurrently with the dividend or distribution to the holders
of shares of Common Stock (provided, however, to the extent that a Holder’s right to participate in any such dividend or
distribution would result in such Holder exceeding the Maximum Percentage, then such Holder shall not be entitled to participate
in such dividend or distribution to such extent (or the beneficial ownership of any such shares of Common Stock as a result of
such dividend or distribution to such extent) and such dividend or distribution to such extent 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 Maximum Percentage).

 

17.             
Vote to Change the Terms of or Issue Preferred Shares. In addition to any other rights provided by law, except where
the vote or written consent of the holders of a greater number of shares is required by law or by another provision of the Articles
of Incorporation, without first obtaining the affirmative vote at a meeting duly called for such purpose or the written consent
without a meeting of the Required Holders, voting together as a single class, the Company shall not: (a) amend or repeal any provision
of, or add any provision to, its Articles of Incorporation or bylaws, or file any certificate of designations or articles of amendment
of any series of shares of preferred stock, if such action would adversely alter or change in any respect the preferences, rights,
privileges or powers, or restrictions provided for the benefit, of the Preferred Shares, regardless of whether any such action
shall be by means of amendment to the Articles of Incorporation or by merger, consolidation or otherwise; (b) increase or decrease
(other than by conversion) the authorized number of Preferred Shares; (c) without limiting any provision of Section 2, create
or authorize (by reclassification or otherwise) any new class or series of shares that has a preference over or is on a parity
with the Preferred Shares with respect to dividends or the distribution of assets on the liquidation, dissolution or winding up
of the Company; (d) purchase, repurchase or redeem any shares of capital stock of the Company junior in rank to the Preferred
Shares (other than pursuant to equity incentive agreements (that have in good faith been approved by the Board) with employees
giving the Company the right to repurchase shares upon the termination of services); (e) without limiting any provision of Section
2, pay dividends or make any other distribution on any shares of any capital stock of the Company junior in rank to the Preferred
Shares; (f) issue any Preferred Shares other than pursuant to the Securities Purchase Agreement; or (g) without limiting any provision
of Section 20, whether or not prohibited by the terms of the Preferred Shares, circumvent a right of the Preferred Shares.

 

    	31

    	 

    
 

18.             
Lost or Stolen Certificates. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the
loss, theft, destruction or mutilation of any certificates representing Preferred Shares (as to which a written certification and
the indemnification contemplated below shall suffice as such evidence), and, in the case of loss, theft or destruction, of an indemnification
undertaking by the applicable Holder to the Company in customary and reasonable form and, in the case of mutilation, upon surrender
and cancellation of the certificate(s), the Company shall execute and deliver new certificate(s) of like tenor and date.

 

19.             
Remedies, Characterizations, Other Obligations, Breaches and Injunctive Relief. The remedies provided in this Certificate
of Designations shall be cumulative and in addition to all other remedies available under this Certificate of Designations and
any of the other Transaction Documents, at law or in equity (including a decree of specific performance and/or other injunctive
relief), and no remedy contained herein shall be deemed a waiver of compliance with the provisions giving rise to such remedy.
Nothing herein shall limit any Holder’s right to pursue actual and consequential damages for any failure by the Company
to comply with the terms of this Certificate of Designations. The Company covenants to each Holder that there shall be no characterization
concerning this instrument other than as expressly provided herein. Amounts set forth or provided for herein with respect to payments,
conversion and the like (and the computation thereof) shall be the amounts to be received by a Holder and shall not, except as
expressly provided herein, be subject to any other obligation of the Company (or the performance thereof). The Company acknowledges
that a breach by it of its obligations hereunder will cause irreparable harm to the Holders and that the remedy at law for any
such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, each Holder
shall be entitled, in addition to all other available remedies, to an injunction restraining any such breach or any such threatened
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 a Holder that is requested by such Holder to enable such Holder to confirm the Company’s
compliance with the terms and conditions of this Certificate of Designations (including, without limitation, compliance with Section
11(a)).

 

    	32

    	 

    
 

20.             
Noncircumvention. The Company hereby covenants and agrees that the Company will not, by amendment of its Articles
of Incorporation, bylaws 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 Certificate of Designations, and will at all times in good faith carry out all the provisions of this Certificate
of Designations and take all action as may be required to protect the rights of the Holders. Without limiting the generality of
the foregoing or any other provision of this Certificate of Designations, the Company (i) shall not increase the par value
of any shares of Common Stock receivable upon the conversion of any Preferred Shares above the Conversion Price then in effect,
(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 non-assessable shares of Common Stock upon the conversion of Preferred Shares and (iii) shall, so long as any Preferred
Shares are outstanding, take all action 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 Preferred Shares, the maximum number of shares of Common Stock
as shall from time to time be necessary to effect the conversion of the Preferred Shares then outstanding (without regard to any
limitations on conversion contained herein).
