not there are profits, surplus or other funds of the Corporation legally
available for the payment of dividends.  Payment of dividends in
shares of Common Stock or additional shares of Series B Preferred Stock (as
applicable) shall be made in a manner consistent with Section 6(e)(i)
herein and, solely for purposes of the payment of dividends in shares, the
Dividend Payment Date shall be deemed to be the Conversion
Date.  Dividends shall cease to accrue with respect to any Series B
Preferred Stock when converted.  Except as otherwise provided herein,
if at any time the Corporation pays dividends partially in cash and partially in
shares of Common Stock and/or Series B Preferred Stock, then such payment shall
be distributed ratably among the Holders based upon the number of shares of
Series B Preferred Stock held by each Holder on such Dividend Payment
Date.

    


    d)           Other
Securities.  So long as any Series B Preferred Stock shall
remain outstanding: (i) neither the Corporation nor any Subsidiary thereof shall
redeem, purchase or otherwise acquire directly or indirectly any Junior
Securities; and (ii) the Corporation and any Subsidiaries thereof shall only
redeem, repurchase or otherwise acquire, directly or indirectly, any Parity
Securities ratably with the Series B Preferred Stock on a pari passu
basis.  So long as any Series B Preferred Stock shall remain
outstanding: (i) neither the Corporation nor any Subsidiary thereof shall
directly or indirectly pay or declare any dividend or make any distribution upon
any Junior Securities (other than a dividend or distribution solely in
additional shares of Junior Securities), in each case as long as any dividends
due on the Series B Preferred Stock remain unpaid, nor shall any monies be set
aside for or applied to the purchase or redemption (through a sinking fund or
otherwise) of any Junior Securities; and (ii) the Corporation and any
Subsidiaries thereof shall only, directly or indirectly, pay or declare any
dividend or make any distribution upon any Parity Securities, or set aside or
apply any monies for the purchase or redemption (through a sinking fund or
otherwise) of any Parity Securities, if it simultaneously, on a pari passu basis and ratably
among the holders of the Series A Preferred Stock and the holders of all Parity
Securities, pays or declares a dividend or distribution, or sets aside or
applies monies for the purchase or redemption (through a sinking fund or
otherwise), of the Series B Preferred Stock.

    


    e)           Payment of Dividends in
Kind.  During the period commencing on the Closing Date and
ending on the eighteen (18) month anniversary of the Closing Date, in the event
on any Dividend Payment Date the Registration Statement (as defined in the
Registration Rights Agreement) has not been declared effective in accordance
with Section 2(b) of the Registration Rights Agreement, any dividend payable in
Common Stock or Series B Preferred Stock shall accrue and be payable to the
Holders of the Series B Preferred Stock within five (5) business days following
the date that such Registration Statement is declared effective.  In
the event on any Dividend Payment Date following the eighteen (18) month
anniversary of the Closing Date, the Registration Statement has not been
declared effective or the Corporation has failed to maintain its effectiveness
during the Effectiveness Period (as defined in the Registration Rights
Agreement), all dividends payable to the Holders of the Series B Preferred Stock
shall be payable, if funds are legally available for payment, in cash only. If
such funds are not legally available for payment, any dividend payable shall
accrue and be immediately payable to the Holders of the Series B Preferred Stock
in cash, when such funds become legally available, or, at the option of the
Corporation, subject to the effectiveness on such date of the Registration
Statement, as otherwise provided for herein; provided however, that if such
funds are not legally available and the Registration Statement is not effective,
the Holders of the Series B Preferred Stock can waive the requirement that the
Registration Statement be effective and elect to received dividend payments as
otherwise provided for herein.

    


    Section
4.  Voting
Rights.

    


    a)           Except
as otherwise provided herein or as otherwise required by law, each Holder of
Series B Preferred Stock shall: (i) be entitled to notice of any annual or
special meeting of the stockholders of the Corporation, at the same time and in
the same manner as of the holders of Common Stock in accordance with the by-laws
of the Corporation; and (ii) vote together with the Common Stock at any annual
or special meeting of the stockholders of the Corporation, or in any action by
written consent of stockholders of the Corporation in lieu of meeting, on an
as-converted to Common Stock basis, with each share of Series B Preferred Stock
entitling its Holder to the number of votes equal the number of shares of Common
Stock into which such share of Series B Preferred Stock could be converted under
this Certificate of Designation as of the close of business on the record date
fixed for such meeting or the effective date of such written
consent.

any matter submitted to vote of the holders of Preferred Stock, voting as a
separate class (as opposed to voting with the holders of Common Stock as
provided in Section
4(a)).

    


    Section
5.  Liquidation and Change of
Control Transactions.  Upon any liquidation, dissolution or
winding-up of the Corporation, whether voluntary or involuntary (a “Liquidation”) or a
Change of Control Transaction, the Holders shall be entitled to receive out of
the assets, whether capital or surplus, of the Corporation in the case of a
Liquidation, or out of the aggregate consideration received by the Corporation
and its stockholders  in the case of a  Change of Control
Transaction, an amount equal to (i) the Stated Value, plus any accrued and
unpaid dividends on the Series B Preferred Stock, together with any other fees
then due and owing thereon under this Certificate of Designation, for each share
of  Series B Preferred Stock, on a pari passu basis with any
distribution or payment upon a Liquidation or Change of Control Transaction to
the holders of Parity Securities and before any distribution or payment shall be
made to the holders of any Junior Securities, plus (ii) the amount
the Holders would have been entitled to receive as holders of the number of
shares of Common Stock for which the shares of Series B Preferred Stock are
convertible immediately prior to such Liquidation or Change of Control
Transaction, on a pari
passu basis with any distribution or payment upon a Liquidation or Change
of Control Transaction to the holders of Parity Securities and Junior Securities
combined. If the assets of the Corporation or aggregate consideration received
shall be insufficient to pay in full the respective preference amounts to the
Holders of Series B Preferred Stock and the holders of any Parity Securities
described in this Section 5, then the
entire assets of the Corporation or aggregate consideration shall be ratably
distributed among the Holders of Series B Preferred Stock and the holders of any
Parity Securities, in accordance with the respective amounts that would be
payable on such shares if all amounts payable thereon were paid in
full.  The Corporation shall mail written notice of any Liquidation,
not less than 45 days prior to the payment date stated therein, to each Holder.
The Corporation shall provide each Holder with
reasonable advance notice (a “Notice of COC”) of the occurrence of a Change of Control Transaction
or potential Change of Control Transaction, which shall specify, for each
Holder, the number of shares of Series B Preferred Stock
owned on the date of such Notice of COC, the number of shares of Common Stock
issuable upon conversion of such Series B Preferred Stock
and the date, if known, on which such Change of Control Transaction is to be
effected, which date may not be prior to the date the Corporation delivers such
Notice of COC to the Holders.  The calculations and entries set forth
in the Notice of COC shall control in the absence of manifest or mathematical
error.  Each Holder shall deliver the certificate(s) representing the
shares of Series B Preferred Stock as instructed in the Notice of
COC.

    


    Section
6.  Conversion.

    


    a)           Conversions at Option of
Holder.  Each share of Series B Preferred Stock shall be
convertible, at any time and from time to time from and after the Closing Date
at the option of the Holder thereof, into that number of shares of Common Stock
determined by dividing the Stated Value of such share of Series B Preferred
Stock by the Conversion Price then in effect.  Holders shall
effect  voluntary conversions pursuant to this Section 6(a) by
providing the Corporation with the form of conversion notice attached hereto as
Annex A (a
“Notice of
Elective
Conversion”).  Each
Notice of Elective Conversion shall specify the number of shares of Series B
Preferred Stock to be converted, the number of shares of Series B Preferred
Stock owned prior to the conversion at issue, the number of shares of Series B
Preferred Stock owned subsequent to the conversion at issue and the date on
which such conversion is to be effected, which date may not be prior to the date
the applicable Holder delivers such Notice of Conversion to the Corporation
(such date, the “Elective Conversion
Date”).  If no Elective Conversion Date is specified in a
Notice of Elective Conversion, the Elective Conversion Date shall be the date
that such Notice of Elective Conversion is delivered hereunder.  The
calculations and entries set forth in the Notice of Elective Conversion shall
control in the absence of manifest or mathematical error.  To effect
elective conversions of shares of Series B Preferred Stock pursuant to this
Section 6(a), a
Holder shall not be required to surrender the certificate(s) representing the
shares of Series B Preferred Stock to the Corporation unless all of the shares
of Series B Preferred Stock represented thereby are so converted, in which case
such Holder shall deliver the certificate representing such shares of Series B
Preferred Stock promptly following the Elective Conversion Date at
issue.  Any certificate representing shares of Series B Preferred
Stock that have been converted in whole or part by such Holder shall be void and
should be destroyed upon receipt of replacement certificate(s) from the
Corporation.  Shares of Series B Preferred Stock converted into Common
Stock pursuant to this Section 6(a) shall be
canceled and shall not be reissued.

    c)           Automatic Conversion Upon
Sufficient VWAP.  If: (i) the VWAP for each of any twenty (20)
Trading Days during any thirty (30) consecutive Trading Day period starting on
or after the Effective Date (“Threshold Period”),
exceeds $4.50 (subject to adjustment for forward and reverse stock splits,
recapitalizations, stock dividends and the like after the Closing Date); and
(ii) all of the Equity Conditions have been met on each Trading Day during the
applicable Threshold Period through and including the later of the VWAP
Automatic Conversion Date and the Trading Day after the date that the Conversion
Shares issuable pursuant to such conversion are actually delivered to the
Holders pursuant to the Notice of VWAP Automatic Conversion, then all
outstanding shares of Series B Preferred Stock shall automatically be converted
into shares of Common Stock, based on the then-effective Conversion
Price.  The Corporation shall provide each Holder with notice (a
“Notice of VWAP
Automatic Conversion”) of the occurrence of an automatic conversion of
the Series B Preferred Stock pursuant to this Section 6(c) within
one (1) Trading Day after the end of any such Threshold Period, which shall
specify, for each Holder, the number of shares of Series B Preferred Stock owned
prior to the automatic conversion at issue, the number of shares of Common Stock
issuable upon conversion of such Series B Preferred Stock and the date on which
such automatic conversion is to be effected, which shall be the third Trading
Day following the date the Corporation delivers such Notice of VWAP Automatic
Conversion to the Holders (such date, the “VWAP Automatic Conversion
Date”).  The calculations and entries set forth in the Notice
of VWAP Automatic Conversion shall control in the absence of manifest or
mathematical error.  Each Holder shall deliver the certificate(s)
representing all of its shares of Series B Preferred Stock to the Corporation
promptly following the VWAP Automatic Conversion Date.  Shares of
Series B Preferred Stock converted into Common Stock pursuant to this Section 6(c) shall be
canceled and shall not be reissued.

    


    d)           Conversion
Price.  The conversion price for the Series B Preferred Stock
shall initially equal $1.65, subject to adjustment herein (the “Conversion
Price”).

    


    e)           Mechanics of
Conversion

    


    i.           Delivery of Certificate Upon
Conversion.  Not later than three (3) Trading Days after each
Conversion Date, the Corporation shall deliver, or cause to be delivered, to the
converting Holder (A) a certificate or certificates representing the Conversion
Shares which, on or after the earlier of: (1) the six (6) month anniversary of
the Closing Date; or (2) the Effective Date, shall be free of restrictive
legends and trading restrictions (other than those which may then be required by
the Purchase Agreement) representing the number of Conversion Shares being
acquired upon the conversion of the Series B Preferred Stock, and/or (B) a bank
check in the amount of accrued and unpaid dividends and, if applicable, the
Make-Whole Payment (to the extent that the Corporation has elected to pay
accrued dividends or the Make-Whole Payment in cash).  On or after the
earlier of: (1) the six (6) month anniversary of the Closing Date or (2) the
Effective Date, the Corporation shall use commercially reasonable efforts to
deliver any certificate or certificates required to be delivered by the
Corporation under this Section 6
electronically through the Depository Trust Company or another established
clearing corporation performing similar functions.

    ii.          Obligation
Absolute.  The Corporation’s obligation to issue and deliver
the Conversion Shares upon conversion of Series B Preferred Stock in accordance
with the terms hereof are absolute and unconditional, irrespective of any action
or inaction by a Holder to enforce the same, any waiver or consent with respect
to any other provision hereof, the recovery of any judgment against any Person
or any action to enforce the same, or any setoff, counterclaim, recoupment,
limitation or termination, or any breach or alleged breach by such Holder or any
other Person of any obligation to the Corporation or any violation or alleged
violation of law by such Holder or any other Person, and irrespective of any
other circumstance which might otherwise limit such obligation of the
Corporation to such Holder in connection with the issuance of such Conversion
Shares; provided,
however, that such delivery shall not operate as a waiver by the
Corporation of any such action that the Corporation may have against such Holder
or such other Person.  In the event a Holder shall elect to convert
any or all of its Series B Preferred Stock, the Corporation may not refuse
conversion based on any claim that such Holder or any one associated or
affiliated with such Holder has been engaged in any violation of law, agreement
or for any other reason, unless an injunction from a court, on notice to Holder,
restraining and/or enjoining conversion of all or part of the Series B Preferred
Stock of such Holder shall have been sought and obtained.  In the
absence of such injunction, the Corporation shall issue Conversion Shares and,
if applicable, cash, upon a properly noticed conversion.  Nothing
herein shall limit a Holder’s right to pursue actual damages or all other
remedies available to it hereunder, at law or in equity including, without
limitation, a decree of specific performance and/or injunctive
relief.  The exercise of any such rights shall not prohibit a Holder
from seeking to enforce damages pursuant to any other Section hereof or under
applicable law.

    


    iii.         Liquidated
Damages.  If the Corporation fails to deliver to a Holder such
certificate or certificates representing Conversion Shares within five (5)
Trading Days after the Elective Conversion Date provided in a Notice of Elective
Conversion pursuant to Section 6(a), the Corporation shall pay to such Holder,
in cash, as liquidated damages and not as a penalty, for each share of Series B
Preferred Stock elected to be converted, $50 per Trading Day for each Trading
Day after such fifth (5th) Trading Day after the Elective Conversion Date until
such certificates are delivered or such Holder is reimbursed in accordance with
Section 6(e)(iv). Nothing herein shall limit a Holder’s right to pursue actual
damages for the Corporation’s failure to deliver Conversion Shares and such
Holder shall have the right to pursue all remedies available to it hereunder, at
law or in equity including, without limitation, a decree of specific performance
and/or injunctive relief.  The exercise of any such rights shall not
prohibit a Holder from seeking to enforce damages pursuant to any other Section
hereof or under applicable law.

    


    iv.         Compensation for Buy-In on
Failure to Timely Deliver Certificates Upon Conversion.  If the
Corporation fails to deliver to a Holder the applicable certificate or
certificates within five (5) Trading Days after the Elective Conversion Date,
and if after such date such Holder is required by its brokerage firm to purchase
(in an open market transaction or otherwise), or the Holder’s brokerage firm
purchases, shares of Common Stock to deliver in satisfaction of a sale by such
Holder of the Conversion Shares which such Holder was entitled to receive upon
the conversion relating to such Notice of Elective Conversion (a “Buy-In”), then the
Corporation shall (A) pay in cash to such Holder (in addition to any other
remedies available to or elected by such Holder) the amount by which (x) such
Holder’s total purchase price (including any brokerage commissions) for the
shares of Common Stock so purchased exceeds (y) the product of (1) the aggregate
number of shares of Common Stock that such Holder was entitled to receive from
the conversion at issue multiplied by (2) the actual sale price at which the
sell order giving rise to such purchase obligation was executed (including any
brokerage commissions) and (B) at the option of such Holder, either reissue (if
surrendered) the shares of Series B Preferred Stock equal to the number of
shares of Series B Preferred Stock submitted for conversion or deliver to such
Holder the number of shares of Common Stock that would have been issued if the
Corporation had timely complied with the Notice of Elective Conversion. For
example, if a Holder purchases shares of Common Stock having a total purchase
price of $11,000 to cover a Buy-In with respect to an attempted conversion of
shares of Series B Preferred Stock with respect to which the actual sale price
(including any brokerage commissions) giving rise to such purchase obligation
was a total of $10,000 under clause (A) of the immediately preceding sentence,
the Corporation shall be required to pay such Holder $1,000. The Holder shall
provide the Corporation written notice indicating the amounts payable to such
Holder in respect of the Buy-In and, upon request of the Corporation, evidence
of the amount of such loss. Nothing herein shall limit a Holder’s right to
pursue any other remedies available to it hereunder, at law or in equity
including, without limitation, a decree of specific performance and/or
injunctive relief with respect to the Corporation’s failure to timely deliver
certificates representing shares of Common Stock upon conversion of the shares
of Series B Preferred Stock as required pursuant to the terms
hereof.

    v.         Reservation of Shares
Issuable Upon Conversion.  The Corporation covenants that it
will, at all times while any Series B Preferred Stock: (A) remains outstanding
or (B) is reserved for issuance or otherwise issuable under any promissory note
or agreement to which the Corporation is a party, reserve and keep available out
of its authorized and unissued shares of Common Stock, for the sole purpose of
issuance upon conversion of such Series B Preferred Stock, free from preemptive
rights or any other purchase rights of Persons other than the Holder (and the
other holders of the Series B Preferred Stock), not less than 130% of the
aggregate number of shares of the Common Stock as shall be issuable (taking into
account the adjustments and restrictions of Section 7) upon: (A)
the conversion of such Series B Preferred Stock; and (B) payment of dividends on
such Series B Preferred Stock in shares of Common Stock
hereunder.  The Corporation covenants that it will, at all times while
any Series B Preferred Stock: (A) remains outstanding or (B) is reserved for
issuance or otherwise issuable under any promissory note or agreement to which
the Corporation is a party, reserve and keep available out of its authorized and
unissued shares of Preferred Stock, for the sole purpose of issuance upon
payment of dividends on such Series B Preferred Stock in additional shares of
Series B Preferred Stock as herein provided, free from preemptive rights or any
other purchase rights of Persons other than the Holder (and the other holders of
the Series B Preferred Stock), not less than 130% of the aggregate number of
shares of the Series B Preferred Stock as shall (subject to the terms and
conditions set forth in the Purchase Agreement) be issuable (taking into account
the adjustments and restrictions of Section 7) upon the
payment of dividends on such Series B Preferred Stock in additional shares of
Series B Preferred Stock hereunder.  The Corporation covenants that
all shares of Common Stock and Series B Preferred Stock that shall be so
issuable shall, upon issue, be duly authorized, validly issued, fully paid and
nonassessable and, if the Conversion Shares Registration Statement is then
effective under the Securities Act, shall be, with respect to such Common Stock
and the Common Stock issuable upon conversion of such Series B Preferred Stock,
registered for public resale in accordance with such Conversion Shares
Registration Statement (subject to such Holder’s compliance with its obligations
under the Registration Rights Agreement).

    


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

    vii.        Transfer
Taxes.  The issuance of certificates for shares of the Common
Stock upon conversion of the Series B Preferred Stock shall be made without
charge to any Holder for any documentary stamp or similar taxes that may be
payable in respect of the issue or delivery of such certificates, provided that the Corporation
shall not be required to pay any tax that may be payable in respect of any
transfer involved in the issuance and delivery of any such certificate upon
conversion in a name other than that of the Holders of such shares of Series B
Preferred Stock and the Corporation shall not be required to issue or deliver
such certificates unless or until the Person or Persons requesting the issuance
thereof shall have paid to the Corporation the amount of such tax or shall have
established to the satisfaction of the Corporation that such tax has been
paid.

    


    Section
7.  Certain
Adjustments.

    


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

    


    b)           Subsequent Equity
Sales.  If, at any time while any Series B Preferred Stock is
outstanding, the Corporation or any Subsidiary, as applicable, sells or grants
any option to purchase or sells or grants any right to reprice, or otherwise
disposes of or issues (or announces any sale, grant or any option to purchase or
reprice or other disposition), any Common Stock or Common Stock Equivalents
(“Additional Shares of
Common Stock”) at an effective price per share of Common Stock that is
lower than the lower of: (i) 93% of the average of the VWAPs for the 10
consecutive Trading Days ending on the Trading Day that is immediately prior to
the date of issuance of the Additional Shares of Common Stock; or (ii) the then
effective Conversion Price of the Series A-1 Preferred A-1 Stock and the Series
A-2 Preferred Stock (“Preferred A”)(such
lower price, the “Base
Conversion Price” and such issuances, collectively, a “Dilutive Issuance”)
(if the holder of the Additional Shares of Common Stock so issued shall at any
time, whether by operation of purchase price adjustments, reset provisions,
floating conversion, exercise or exchange  prices or otherwise, or due
to warrants, options or rights per share which are issued in connection with
such issuance, be entitled to receive shares of Common Stock or Common Stock
Equivalents at an effective price per share that is lower than the Conversion
Price, such issuance shall be deemed to have occurred for less than the
Conversion Price on the date of the Dilutive Issuance), then the Conversion
Price shall be reduced to equal the price determined by multiplying the
Conversion Price in effect immediately prior to such issuance by a
fraction:

    


    i.           the
numerator of which shall be: (A) the number of shares of Common Stock issuable
upon the conversion of the Series B Preferred Stock immediately prior to such
Dilutive Issuance, plus
(B) the number of shares of Common Stock or Common Stock Equivalents
which the Aggregate Consideration received or deemed to be received by the
Corporation for the total number of Additional Shares of Common Stock so issued
would purchase at such then-existing Base Conversion Price; and

    EXHIBIT
4.3

    


    ii.          the
denominator of which shall be the number of shares of Common Stock issuable upon
the conversion of the Series B Preferred Stock immediately prior to such
Dilutive Issuance plus
the total number of Additional Shares of Common Stock actually so
issued.

    


    Such
adjustment shall be made upon any issuance of Additional Shares of Common Stock;
provided, however, that
no adjustment will be made under this Section 7(b) in
respect of an Exempt Issuance.  The Corporation shall notify the
Holders in writing, no later than the Trading Day following the issuance of any
Additional Shares of Common Stock subject to this Section 7(b),
indicating therein the applicable issuance price, or applicable reset price,
exchange price, conversion price and other pricing terms (such notice, the
“Dilutive Issuance
Notice”).  For purposes of clarification, whether or not the
Corporation provides a Dilutive Issuance Notice pursuant to this Section 7(b), upon
the occurrence of any Dilutive Issuance, the Holders are entitled to receive a
number of Conversion Shares based upon the Base Conversion Price on or after the
date of such Dilutive Issuance, regardless of whether a Holder accurately refers
to the Base Conversion Price in the Notice of Conversion.

    


    c)           Pro Rata
Distributions.  If the Corporation, at any time while any
Series B Preferred Stock is outstanding, distributes to all holders of Common
Stock (and not to the Holders) evidences of its indebtedness or assets
(including cash and cash dividends) or rights or warrants to subscribe for or
purchase any security (other than the Common Stock, which shall be subject to
Section 7(b)),
then in each such case the Conversion Price shall be adjusted by multiplying
such Conversion Price in effect immediately prior to the record date fixed for
determination of stockholders entitled to receive such distribution by a
fraction of which the denominator shall be the VWAP determined as of the record
date mentioned above, and of which the numerator shall be such VWAP on such
record date less the then fair market value at such record date of the portion
of such assets or evidence of indebtedness or rights or warrants so distributed
applicable to one outstanding share of Common Stock as determined by the Board
of Directors of the Corporation in good faith.  In either case the
adjustments shall be described in a statement delivered to the Holders
describing the portion of assets or evidences of indebtedness so distributed or
such subscription rights applicable to one share of Common
Stock.  Such adjustment shall be made whenever any such distribution
is made and shall become effective immediately after the record date mentioned
above.

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

    


    e)           Calculations.  All
calculations under this Section 7 shall be
made to the nearest cent or the nearest 1/100th of a share, as the case may
be.  For purposes of this Section 7, the number
of shares of Common Stock deemed to be issued and outstanding as of a given date
shall be the sum of the number of shares of Common Stock (excluding any treasury
shares of the Corporation) issued and outstanding.

    i.           Adjustment to Conversion
Price.  Whenever the Conversion Price is adjusted pursuant to
any provision of this Section 7, the
Corporation shall promptly deliver to each Holder a notice setting forth the
Conversion Price after such adjustment and setting forth a brief statement of
the facts requiring such adjustment.

    


    ii.          Notice to Allow Conversion

redemption of the Common Stock, (C) the Corporation shall authorize the granting

all of the assets of the Corporation, or any compulsory share exchange whereby
the Common Stock is converted into other securities, cash or property or (E) the
Corporation shall authorize the voluntary or involuntary dissolution,
liquidation or winding up of the affairs of the Corporation, then, in each case,
the Corporation shall cause to be filed at each office or agency maintained for
the purpose of conversion of the Series B Preferred Stock, and shall cause to be
delivered to each Holder at its last address as it shall appear upon the stock
books of the Corporation, at least twenty (20) calendar days prior to the
applicable record or effective date hereinafter specified, a notice stating (x)
the date on which a record is to be taken for the purpose of such dividend,
distribution, redemption, rights or warrants, or if a record is not to be taken,
the date as of which the holders of the Common Stock of record to be entitled to
such dividend, distributions, redemption, rights or warrants are to be
determined or (y) the date on which such reclassification, consolidation,
merger, sale, transfer or share exchange is expected to become effective or
close, and the date as of which it is expected that holders of the Common Stock
of record shall be entitled to exchange their shares of the Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer or share exchange, provided that the failure to
deliver such notice or any defect therein or in the delivery thereof shall not
affect the validity of the corporate action required to be specified in such
notice.  To the extent that any notice provided hereunder constitutes,
or contains, material, non-public information regarding the Corporation or any
of the Subsidiaries, the Corporation shall, as required by applicable federal
securities law, file such notice with the Commission pursuant to a Current
Report on Form 8-K.  The Holder shall remain entitled to convert the
Series B Preferred Stock during the 20-day period commencing on the date of such
notice through the effective date of the event triggering such notice, except as
may otherwise be expressly set forth herein.

    Section
9.  Preemptive
Rights.

    


    a)           From
the date hereof until such time all Holders no longer hold any shares
of  Series B Preferred Stock, upon any issuance by the Corporation or
any of its Subsidiaries of Common Stock, Common Stock Equivalents for cash
consideration, or a combination of units hereof (a “Subsequent
Financing”), each Holder, collectively with all holders of Parity
Securities, shall have the right to participate in up to an amount of the
Subsequent Financing equal to 100% of the Subsequent Financing (the “Participation
Maximum”) on the same terms, conditions and price provided for in the
Subsequent Financing.

    


    b)           At
least five (5) Trading Days prior to the closing of the Subsequent Financing,
the Corporation shall deliver to each Holder a written notice of its intention
to effect a Subsequent Financing (“Pre-Notice”), which
Pre-Notice shall ask such Holder if it wants to review the details of such
financing (such additional notice, a “Subsequent Financing
Notice”).  Upon the request of a Holder, and only upon a
request by such Holder, for a Subsequent Financing Notice, the Corporation shall
promptly, but no later than one (1) Trading Day after such request, deliver a
Subsequent Financing Notice to such Holder.  The Subsequent Financing
Notice shall describe in reasonable detail the proposed terms of such Subsequent
Financing, the amount of proceeds intended to be raised thereunder and the
Person or Persons through or with whom such Subsequent Financing is proposed to
be effected and shall include a term sheet or similar document relating thereto
as an attachment.

    


    c)           Any
Holder desiring to participate in such Subsequent Financing must provide written
notice to the Corporation by not later than 5:30 p.m. (New York City time) on
the fourth (4th)
Trading Day after all of the Holders have received the Pre-Notice that the
Holder is willing to participate in the Subsequent Financing, the amount of the
Holder’s participation, and representing and warranting that the Holder has such
funds ready, willing, and available for investment on the terms set forth in the
Subsequent Financing Notice.  If the Corporation receives no such
notice from a Holder as of such fourth (4th)
Trading Day, such Holder shall be deemed to have notified the Corporation that
it does not elect to participate.

    d)           If
by 5:30 p.m. (New York City time) on the fourth (4th) Trading
Day after all of the Holders have received the Pre-Notice, notifications by the
Holders and holders of Parity Securities of their willingness to participate in
the Subsequent Financing (or to cause their designees to participate) is, in the
aggregate, less than the total amount of the Subsequent Financing, then the
Corporation may effect the remaining portion of such Subsequent Financing on the
terms and with the Persons set forth in the Subsequent Financing
Notice.

    


    e)           If
by 5:30 p.m. (New York City time) on the fourth (4th)
Trading Day after all of the Holders have received the Pre-Notice, the
Corporation receives responses to a Subsequent Financing Notice from Holders and
holders of Parity Securities seeking to purchase more than the aggregate amount
of the Participation Maximum, each such Holder shall have the right to purchase
its Pro Rata Portion (as defined below) of the Participation
Maximum.  “Pro Rata Portion” of
a Holder means the ratio of: (x) the aggregate Stated Value of the Parity
Securities issued to such Holder on the Closing Date; and (y) the aggregate
Stated Value of the Parity Securities issued to all holders of Parity Securities
participating in such Subsequent Financing under this Section 9.

    


    f)           The
Corporation must provide the Holders with a second Subsequent Financing Notice,
and the Holders will again have the right of participation set forth above in
this Section 9,
if the Subsequent Financing subject to the initial Subsequent Financing Notice
is not consummated for any reason on the terms set forth in such Subsequent
Financing Notice within thirty (30) Trading Days after the date of the initial
Subsequent Financing Notice.

    


    g)           Notwithstanding
the foregoing, this Section 9 shall not
apply in respect of (i) an Exempt Issuance or (ii) an underwritten public
offering of Common Stock.

    


    Section
10.  Miscellaneous.

nationally recognized overnight courier service addressed to each Holder at the
address of such Holder appearing on the books of the Corporation, or if no such

business of such Holder, as set forth in the Purchase Agreement.  Any
notice or other communication or deliveries hereunder shall be deemed given and
effective on the earliest of (i) the second Trading Day following the date of
mailing, if sent by U.S. nationally recognized overnight courier service, or
(ii) upon actual receipt by the party to whom such notice is required to be
given.

    


    b)           Absolute
Obligation.  Except as expressly provided herein, no provision
of this Certificate of Designation shall alter or impair the obligation of the
Corporation, which is absolute and unconditional, to pay accrued dividends on
the shares of Series B Preferred Stock at the time, place, and rate, and in the
coin, currency or shares (as applicable), herein prescribed.

    


    c)           Lost or Mutilated Series B
Preferred Stock Certificate.  If a Holder’s Series B Preferred
Stock certificate shall be mutilated, lost, stolen or destroyed, the Corporation
shall execute and deliver, in exchange and substitution for and upon
cancellation of a mutilated certificate, or in lieu of or in substitution for a
lost, stolen or destroyed certificate, a new certificate for the shares of
Series B Preferred Stock so mutilated, lost, stolen or destroyed, but only upon
receipt of evidence of such loss, theft or destruction of such certificate, and
of the ownership hereof reasonably satisfactory to the
Corporation.

    d)           Governing
Law.  All questions concerning the construction, validity,
enforcement and interpretation of this Certificate of Designation shall be
governed by and construed and enforced in accordance with the internal laws of
the State of Nevada, without regard to the principles of conflict of laws
thereof.  The Corporation and each Holder agrees that all legal
proceedings concerning the interpretation, enforcement and defense of the
transactions contemplated by any of the Transaction Documents (whether brought
against a party hereto or its respective Affiliates, directors, officers,
shareholders, employees or agents) shall be commenced in the state and federal
courts sitting in the City of New York, Borough of Manhattan (the “New York
Courts”).  The Corporation and each Holder hereby irrevocably
submits to the exclusive jurisdiction of the New York Courts for the
adjudication of any dispute hereunder or in connection herewith or with any
transaction contemplated hereby or discussed herein (including with respect to
the enforcement of any of the Transaction Documents), and hereby irrevocably
waives, and agrees not to assert in any suit, action or proceeding, any claim
that it is not personally subject to the jurisdiction of such New York Courts,
or such New York Courts are improper or inconvenient venue for such
proceeding.  The Corporation and each Holder hereby irrevocably waives
personal service of process and consents to process being served in any such
suit, action or proceeding by mailing a copy thereof via registered or certified
mail or overnight delivery (with evidence of delivery) to it at the address in
effect for notices to it under this Certificate of Designation and agrees that
such service shall constitute good and sufficient service of process and notice
thereof.  Nothing contained herein shall be deemed to limit in any way
any right to serve process in any other manner permitted by applicable law. The
Corporation and each Holder hereby irrevocably waives, to the fullest extent
permitted by applicable law, any and all right to trial by jury in any legal
proceeding arising out of or relating to this Certificate of Designation or the
transactions contemplated hereby.  If the Corporation or any Holder
shall commence an action or proceeding to enforce any provisions of this
Certificate of Designation, then the prevailing party in such action or
proceeding shall be reimbursed by the other party for its attorneys’ fees and
other costs and expenses incurred in the investigation, preparation and
prosecution of such action or proceeding.

    


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

    


    f)           Severability.  If
any provision of this Certificate of Designation is invalid, illegal or
unenforceable, the balance of this Certificate of Designation shall remain in
effect, and if any provision is inapplicable to any Person or circumstance, it
shall nevertheless remain applicable to all other Persons and
circumstances.  If it shall be found that any interest or other amount
deemed interest due hereunder violates the applicable law governing usury, the
applicable rate of interest due hereunder shall automatically be lowered to
equal the maximum rate of interest permitted under applicable law.

    


    g)           Next Business
Day.  Whenever any payment or other obligation hereunder shall
be due on a day other than a Business Day, such payment shall be made on the
next succeeding Business Day.
