otherwise (in each case in accordance with the terms hereof) and to pay interest
("Interest") on
any outstanding Principal at the applicable Interest Rate from the date set out

notice of conversion) and the Holder may immediately and without expiration of
any grace period enforce any and all of its rights and remedies hereunder and
all other remedies available to it under applicable law. Such declaration may be
rescinded and annulled by Holder at any time prior to payment hereunder. No such
rescission or annulment shall affect any subsequent Event of Default or impair
any right consequent thereon.

    (3)           COMPANY
REDEMPTION.  The Company at its option shall have the right to
redeem (“Optional
Redemption”) a portion or all amounts outstanding under this Debenture
prior to the Maturity Date provided that as of the date of the Holder’s receipt
of a Redemption Notice (as defined herein) there is no Equity Conditions
Failure.  The Company shall pay an amount equal to the principal
amount being redeemed plus a redemption premium (“Redemption Premium”)
equal to fifteen percent (15%) of the Principal amount being redeemed, and
accrued Interest, (collectively referred to as the “Company Additional
Redemption
Amount”).  In order to make a redemption pursuant to this
Section, the Company shall first provide written notice to the Holder of its
intention to make a redemption (the “Redemption Notice”)
setting forth the amount of Principal it desires to redeem.  After
receipt of the Redemption Notice the Holder shall have three (3) Business Days
to elect to convert all or any portion of this Debenture, subject to the
limitations set forth in Section 4(b).  On the fourth (4th) Business
Day after the Redemption Notice, the Company shall deliver to the Holder the
Company Additional Redemption Amount with respect to the Principal amount
redeemed after giving effect to conversions effected during the three (3)
Business Day period.

     

    (4)           CONVERSION OF
DEBENTURE.  This Debenture shall be convertible into shares of
the Company's Common Stock, on the terms and conditions set forth in this
Section 4.

     

    (a)           Conversion
Right.  Subject to the provisions of Section 4(c), at any time
or times on or after the Issuance Date, the Holder shall be entitled to convert
any portion of the outstanding and unpaid Conversion Amount (as defined below)
into fully paid and nonassessable shares of Common Stock in accordance with
Section 4(b), at the Conversion Rate (as defined below).  The number
of shares of Common Stock issuable upon conversion of any Conversion Amount
pursuant to this Section 4(a) shall be determined by dividing (x) such
Conversion Amount by (y) the Conversion Price (the "Conversion
Rate").  The Company shall not issue any fraction of a share of
Common Stock upon any conversion.  If the issuance would result in the
issuance of a fraction of a share of Common Stock, the Company shall round such
fraction of a share of Common Stock up to the nearest whole
share.  The Company shall pay any and all transfer, stamp and similar
taxes that may be payable with respect to the issuance and delivery of Common
Stock upon conversion of any Conversion Amount.

     

    (i)          "Conversion Amount"
means the portion of the Principal and accrued Interest to be converted,
redeemed or otherwise with respect to which this determination is being
made.

     

    (ii)         "Conversion Price"
means, as of any Conversion Date (as defined below) or other date of
determination, the lesser of (a) $0.58 (the “Fixed Conversion
Price”), subject to adjustment as provided herein, or (b) ninety percent
(90%) of the lowest Volume Weighted Average Price during the ten (10) Trading
Days immediately preceding the Conversion Date (the “Market Conversion
Price”).

    (i)          Optional
Conversion.  To convert any Conversion Amount into shares of
Common Stock on any date (a "Conversion Date"),
the Holder shall (A) transmit by facsimile (or otherwise deliver), for receipt
on or prior to 11:59 p.m., New York Time, on such date, a copy of an executed
notice of conversion in the form attached hereto as Exhibit I (the "Conversion Notice")
to the Company and (B) if required by Section 4(b)(iv), surrender this Debenture
to a nationally recognized overnight delivery service for delivery to the
Company (or an indemnification undertaking reasonably satisfactory to the
Company with respect to this Debenture in the case of its loss, theft or
destruction).  On or before the third Business Day following the date
of receipt of a Conversion Notice (the "Share Delivery
Date"), the Company shall (X) if legends are not required to be placed on
certificates of Common Stock pursuant to the Securities Purchase Agreement and
provided that the Transfer Agent is participating in the Depository Trust
Company's ("DTC") Fast Automated
Securities Transfer Program, credit such aggregate number of shares of Common
Stock to which the Holder shall be entitled to the Holder's or its designee's
balance account with DTC through its Deposit Withdrawal Agent Commission system
or (Y) if the Transfer Agent is not participating in the DTC Fast Automated
Securities Transfer Program, issue and deliver to the address as specified in
the Conversion Notice, a certificate, registered in the name of the Holder or
its designee, for the number of shares of Common Stock to which the Holder shall
be entitled which certificates shall not bear any restrictive legends unless
required pursuant to Section 2(g) of the Securities Purchase
Agreement.  If this Debenture is physically surrendered for conversion
and the outstanding Principal of this Debenture is greater than the Principal
portion of the Conversion Amount being converted, then the Company shall as soon
as practicable and in no event later than three (3) Business Days after receipt
of this Debenture and at its own expense, issue and deliver to the holder a new
Debenture representing the outstanding Principal not converted.  The
Person or Persons entitled to receive the shares of Common Stock issuable upon a
conversion of this Debenture shall be treated for all purposes as the record
holder or holders of such shares of Common Stock upon the transmission of a
Conversion Notice.  In the event of a partial conversion of this
Debenture pursuant hereto, the principal amount converted shall be deducted from
the Installment Amounts due on subsequent Installment Dates.

     

    (ii)         Company's Failure to Timely
Convert.  If within three (3) Trading Days after the Company's
receipt of the facsimile copy of a Conversion Notice the Company shall fail to
issue and deliver a certificate to the Holder or credit the Holder's balance
account with DTC for the number of shares of Common Stock to which the Holder is
entitled upon such holder's conversion of any Conversion Amount (a "Conversion Failure"),
and if on or after such Trading Day the Holder purchases (in an open market
transaction or otherwise) Common Stock to deliver in satisfaction of a sale by
the Holder of Common Stock issuable upon such conversion that the Holder
anticipated receiving from the Company (a "Buy-In"), then the
Company shall, within three (3) Business Days after the Holder's request and in
the Holder's discretion, either (i) pay cash to the Holder in an amount equal to
the Holder's total purchase price (including brokerage commissions and other out
of pocket expenses, if any) for the shares of Common Stock so purchased (the
"Buy-In Price"), at which point the
Company's obligation to deliver such certificate (and to issue such Common
Stock) shall terminate, or (ii) promptly honor its obligation to deliver to the
Holder a certificate or certificates representing such Common Stock and pay cash
to the Holder in an amount equal to the excess (if any) of the Buy-In Price over
the product of (A) such number of shares of Common Stock, times (B) the Closing
Bid Price on the Conversion Date.

    (iii)        Book-Entry.
Notwithstanding anything to the contrary set forth herein, upon conversion of
any portion of this Debenture in accordance with the terms hereof, the Holder
shall not be required to physically surrender this Debenture to the Company
unless (A) the full Conversion Amount represented by this Debenture is being
converted or (B) the Holder has provided the Company with prior written notice
(which notice may be included in a Conversion Notice) requesting reissuance of
this Debenture upon physical surrender of this Debenture.  The Holder
and the Company shall maintain records showing the Principal and Interest
converted and the dates of such conversions or shall use such other method,
reasonably satisfactory to the Holder and the Company, so as not to require
physical surrender of this Debenture upon conversion.

     

    (e)           Limitations on
Conversions.

     

    (i)          Beneficial
Ownership.  The Company shall not effect any conversions of
this Debenture and the Holder shall not have the right to convert any portion of
this Debenture or receive shares of Common Stock as payment of interest
hereunder to the extent that after giving effect to such conversion or receipt
of such interest payment, the Holder, together with any affiliate thereof, would
beneficially own (as determined in accordance with Section 13(d) of the Exchange
Act and the rules promulgated thereunder) in excess of 4.99% of the number of
shares of Common Stock outstanding immediately after giving effect to such
conversion or receipt of shares as payment of
interest.    Since the Holder will not be obligated to
report to the Company the number of shares of Common Stock it may hold at the
time of a conversion hereunder, unless the conversion at issue would result in
the issuance of shares of Common Stock in excess of 4.99% of the then
outstanding shares of Common Stock without regard to any other shares which may
be beneficially owned by the Holder or an affiliate thereof, the Holder shall
have the authority and obligation to determine whether the restriction contained
in this Section will limit any particular conversion hereunder and to the extent
that the Holder determines that the limitation contained in this Section
applies, the determination of which portion of the principal amount of this
Debenture is convertible shall be the responsibility and obligation of the
Holder.  If the Holder has delivered a Conversion Notice for a
principal amount of this Debenture that, without regard to any other shares that
the Holder or its affiliates may beneficially own, would result in the issuance
in excess of the permitted amount hereunder, the Company shall notify the Holder
of this fact and shall honor the conversion for the maximum principal amount
permitted to be converted on such Conversion Date in accordance with Section
4(a) and, any principal amount tendered for conversion in excess of the
permitted amount hereunder shall remain outstanding under this Debenture. The
provisions of this Section may be waived by a Holder (but only as to itself and
not to any other Holder) upon not less than 65 days prior notice to the Company.
Other Holders shall be unaffected by any such waiver.

     

    (ii)         The
Holder shall not in any calendar month, without the prior consent of the Company
(which shall not be unreasonably withheld), sell shares of Common Stock obtained
through conversion hereunder at the Market Conversion Price, in excess of the
Collar Amount.

     

    (d)           Other
Provisions.

     

    
      
         

      

      
        7

        
          

        

      

      
         

      

    

    (i)          The
Company shall at all times reserve and keep available out of its authorized
Common Stock the full number of shares of Common Stock issuable upon conversion
of all outstanding amounts under this Debenture; and within three (3) Business
Days following the receipt by the Company of a Holder's notice that such minimum
number of Underlying Shares is not so reserved, the Company shall promptly
reserve a sufficient number of shares of Common Stock to comply with such
requirement.

     

    (ii)         All
calculations under this Section 4 shall be rounded to the nearest $0.0001 or
whole share.

     

    (iii)        The
Company covenants that it will at all times reserve and keep available out of
its authorized and unissued shares of Common Stock solely for the purpose of
issuance upon conversion of this Debenture and payment of interest on this
Debenture, each as herein provided, free from preemptive rights or any other
actual contingent purchase rights of persons other than the Holder, not less
than such number of shares of the Common Stock as shall (subject to any
additional requirements of the Company as to reservation of such shares set
forth in this Debenture or in the Transaction Documents) be issuable (taking
into account the adjustments and restrictions set forth herein) upon the
conversion of the outstanding principal amount of this Debenture and payment of
interest hereunder. The Company covenants that all shares of Common Stock that
shall be so issuable shall, upon issue, be duly and validly authorized, issued
and fully paid, nonassessable and, if the Underlying Shares Registration
Statement has been declared effective under the Securities Act, registered for
public sale in accordance with such Underlying Shares Registration
Statement.

     

    (iv)        Nothing
herein shall limit a Holder's right to pursue actual damages or declare an Event
of Default pursuant to Section 2 herein for the Company 's failure to deliver
certificates representing shares of Common Stock upon conversion within the
period specified herein and such Holder shall have the right to pursue all
remedies available to it at law or in equity including, without limitation, a
decree of specific performance and/or injunctive relief, in each case without
the need to post a bond or provide other security. The exercise of any such
rights shall not prohibit the Holder from seeking to enforce damages pursuant to
any other Section hereof or under applicable law.

     

    (5)           Adjustments to Conversion
Price

     

    (a)           Adjustment of Conversion
Price upon Issuance of Common Stock.  If the Company, at any
time while this Debenture is outstanding, issues or sells, or in accordance with
this Section 5(a) is deemed to have issued or sold, any shares of Common Stock
(other than Excluded Securities), 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 (such price 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 purposes of determining the adjusted Conversion Price
under this Section 5(a), the following shall be applicable:

     

    
      
         

      

      
        8

        
          

        

      

      
         

      

    

    (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 or exchange or
exercise of any Convertible Securities issuable upon exercise of 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, the "lowest price per share for which one share of
Common Stock is issuable upon the exercise of any such Option or upon conversion
or exchange or exercise of any Convertible Securities issuable upon exercise of
such Option" shall be equal to 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 granting or sale of the Option, upon exercise of the Option
and upon conversion or exchange or exercise of any Convertible Security issuable
upon exercise of such Option.  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 Common Stock upon conversion or exchange or exercise 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 such conversion or exchange or exercise 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 the purposes of this Section, the "lowest price per share
for which one share of Common Stock is issuable upon such conversion or exchange
or exercise" shall be equal to 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 issuance or sale of the Convertible Security and upon the
conversion or exchange or exercise of such Convertible Security.  No
further adjustment of the Conversion Price shall be made upon the actual
issuance of such share of Common Stock upon conversion or exchange or exercise
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 had been or are to be made pursuant to other provisions
of this Section, 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 price provided for in any
Options, the additional consideration, if any, payable upon the issue,
conversion, exchange or exercise of any Convertible Securities, or the rate at
which any Convertible Securities are convertible into or exchangeable or
exercisable for Common Stock changes at any time, the Conversion Price in effect
at the time of such change 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 changed purchase price, additional consideration or changed
conversion rate, as the case may be, at the time initially granted, issued or
sold.  For purposes of this Section, if the terms of any Option or
Convertible Security that was outstanding as of the Issuance Date are changed in
the manner described in the immediately preceding sentence, then such Option or
Convertible Security and the Common Stock deemed issuable upon exercise,
conversion or exchange thereof shall be deemed to have been issued as of the
date of such change.  No adjustment shall be made if such adjustment
would result in an increase of the Conversion Price then in effect.

     

    
      
         

      

      
        9

        
          

        

      

      
         

      

    

    (iv)        Calculation of Consideration
Received.  In case any Option is issued in connection with the
issue or sale of other securities of the Company, together comprising one
integrated transaction in which no specific consideration is allocated to such
Options by the parties thereto, the Options will be deemed to have been issued
for the difference of (x) the aggregate fair market value of such Options and
other securities issued or sold in such integrated transaction, less (y) the
fair market value of the securities other than such Option, issued or sold in
such transaction and the other securities issued or sold in such integrated
transaction will be deemed to have been issued or sold for the balance of the
consideration received by the Company.  If any 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
gross amount raised by the Company; provided, however, that such gross amount is
not greater than 110% of the net amount received by the Company
therefor.  If any Common Stock, Options or Convertible Securities are
issued or sold for a consideration other than cash, the amount of the
consideration other than cash received by the Company will be the fair value of
such consideration, except where such consideration consists of securities, in
which case the amount of consideration received by the Company will be the
Closing Bid Price of such securities on the date of receipt.  If any
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 Common Stock, Options or Convertible
Securities, as the case may be.  The fair value of any consideration
other than cash or securities will be determined jointly by the Company and the
Holder.  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) Business
Days after the tenth (10th) day
following the Valuation Event by an independent, reputable appraiser jointly
selected by the Company and the Holder.  The determination of such
appraiser shall be deemed binding upon all parties absent manifest error and the
fees and expenses of such appraiser shall be borne by the Company.

     

    (v)         Record
Date.  If the Company fixes a record date for the purpose of
entitling the holders of Common Stock (A) to receive a dividend or other
distribution payable in Common Stock, Options or in Convertible Securities or
(B) to subscribe for or purchase Common Stock, Options or Convertible
Securities, then such record date will be deemed to be the date of the issue or
sale of the 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.  If the
Company, at any time while this Debenture is outstanding, shall (a) pay a stock
dividend or otherwise make a distribution or distributions on shares of its
Common Stock or any other equity or equity equivalent securities payable in
shares of Common Stock, (b) subdivide outstanding shares of Common Stock into a
larger number of shares, (c) combine (including by way of reverse stock split)
outstanding shares of Common Stock into a smaller number of shares, or (d) issue
by reclassification of shares of the Common Stock any shares of capital stock of
the Company, then the Conversion Price shall be multiplied by a fraction of
which the numerator shall be the number of shares of Common Stock (excluding
treasury shares, if any) outstanding before such event and of which the
denominator shall be the number of shares of Common Stock outstanding after such
event. Any adjustment made pursuant to this Section shall become effective
immediately after the record date for the determination of stockholders entitled
to receive such dividend or distribution and shall become effective immediately
after the effective date in the case of a subdivision, combination or
re-classification.

     

    
      
         

      

      
        10

        
          

        

      

      
         

      

    

    (c)           Purchase
Rights.  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 the Holder will be entitled to acquire, upon the terms applicable to such
Purchase Rights, the aggregate Purchase Rights which the Holder could have
acquired if the Holder had held the number of shares of Common Stock acquirable
upon complete conversion of this Debenture (without taking into account any
limitations or restrictions on the convertibility of this Debenture) immediately
before the record date for the grant, issuance or sale of such Purchase Rights,
or, if no such record date is fixed, 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.

     

    (d)           Other
Events.  If any event occurs of the type contemplated by the
provisions of this Section 5 but not expressly provided for by such provisions
(including, without limitation, the granting of stock appreciation rights,
phantom stock rights or other rights with equity features), then the Company's
Board of Directors will make an appropriate adjustment in the Conversion Price
so as to protect the rights of the Holder under this Debenture; provided that no
such adjustment will increase the Conversion Price as otherwise determined
pursuant to this Section 5.

     

    (e)           Other Corporate
Events.  In addition to and not in substitution for any other
rights hereunder, prior to the consummation of any Fundamental Transaction
pursuant to which holders of shares of Common Stock are entitled to receive
securities or other assets with respect to or in exchange for shares of Common
Stock (a "Corporate
Event"), the Company shall make appropriate provision to insure that the
Holder will thereafter have the right to receive upon a conversion of this
Debenture, at the Holder's option, (i) in addition to the shares of Common Stock
receivable upon such conversion, such securities or other assets to which the
Holder would have been entitled with respect to such shares of Common Stock had
such shares of Common Stock been held by the Holder upon the consummation of
such Corporate Event (without taking into account any limitations or
restrictions on the convertibility of this Debenture) 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 the
Holder would have been entitled to receive had this Debenture initially been
issued with conversion rights for the form of such consideration (as opposed to
shares of Common Stock) at a conversion rate for such consideration commensurate
with the Conversion Rate.  Provision made pursuant to the preceding
sentence shall be in a form and substance satisfactory to the Required
Holders.  The provisions of this Section shall apply similarly and
equally to successive Corporate Events and shall be applied without regard to
any limitations on the conversion or redemption of this Debenture.

     

    
      
         

      

      
        11

        
          

        

      

      
         

      

    

    (f)           Whenever
the Conversion Price is adjusted pursuant to this Section 5, the Company shall
promptly mail to the Holder a notice setting forth the Conversion Price after
such adjustment and setting forth a brief statement of the facts requiring such
adjustment.

     

    (g)           In
case of any (1) merger or consolidation of the Company or any subsidiary of the
Company with or into another Person, or (2) sale by the Company or any
subsidiary of the Company of more than one-half of the assets of the Company in
one or a series of related transactions, a Holder shall have the right to (A)
exercise any rights under Section 2(b), (B) convert the aggregate amount of this
Debenture then outstanding into the shares of stock and other securities, cash
and property receivable upon or deemed to be held by holders of Common Stock
following such merger, consolidation or sale, and such Holder shall be entitled
upon such event or series of related events to receive such amount of
securities, cash and property as the shares of Common Stock into which such
aggregate principal amount of this Debenture could have been converted
immediately prior to such merger, consolidation or sale, or (C) in the case of a
merger or consolidation, require the surviving entity to issue to the Holder a
convertible Debenture with a principal amount equal to the aggregate principal
amount of this Debenture then held by such Holder, plus all accrued and unpaid
interest and other amounts owing thereon, which such newly issued convertible
Debenture shall have terms identical (including with respect to conversion) to
the terms of this Debenture, and shall be entitled to all of the rights and
privileges of the Holder of this Debenture set forth herein and the agreements
pursuant to which this Debenture was issued. In the case of clause (C), the
conversion price applicable for the newly issued Convertible Debenture shall be
based upon the amount of securities, cash and property that each share of Common
Stock would receive in such transaction and the Conversion Price in effect
immediately prior to the effectiveness or closing date for such transaction. The
terms of any such merger, sale or consolidation shall include such terms so as
to continue to give the Holder the right to receive the securities, cash and
property set forth in this Section upon any conversion or redemption following
such event. This provision shall similarly apply to successive such
events.

     

    (6)           REISSUANCE OF THIS
DEBENTURE.

     

    (a)           Transfer.  If
this Debenture is to be transferred, the Holder shall surrender this Debenture
to the Company, whereupon the Company will, subject to the satisfaction of the
transfer provisions of the Securities Purchase Agreement, forthwith issue and
deliver upon the order of the Holder a new Debenture (in accordance with Section
6(d)), registered in the name of the registered transferee or assignee,
representing the outstanding Principal being transferred by the Holder and, if
less than the entire outstanding Principal is being transferred, a new Debenture
(in accordance with Section 6(d)) to the Holder representing the outstanding
Principal not being transferred.  The Holder and any assignee, by
acceptance of this Debenture, acknowledge and agree that, by reason of the
provisions of Section 4(b)(iii) following conversion or redemption of any
portion of this Debenture, the outstanding Principal represented by this
Debenture may be less than the Principal stated on the face of this
Debenture.

     

    (b)           Lost, Stolen or Mutilated
Debenture.  Upon receipt by the Company of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Debenture, and, in the case of loss, theft or destruction, of any
indemnification undertaking by the Holder to the Company in customary form and,
in the case of mutilation, upon surrender and cancellation of this Debenture,
the Company shall execute and deliver to the Holder a new Debenture (in
accordance with Section 6(d)) representing the outstanding
Principal.

     

    
      
         

      

      
        12

        
          

        

      

      
         

      

    

    (c)           Debenture Exchangeable for
Different Denominations.  This Debenture is exchangeable, upon
the surrender hereof by the Holder at the principal office of the Company, for a
new Debenture or Debentures (in accordance with Section 6(d)) representing in
the aggregate the outstanding Principal of this Debenture, and each such new
Debenture will represent such portion of such outstanding Principal as is
designated by the Holder at the time of such surrender.

     

    (d)           Issuance of New
Debentures.  Whenever the Company is required to issue a new
Debenture pursuant to the terms of this Debenture, such new Debenture (i) shall
be of like tenor with this Debenture, (ii) shall represent, as indicated on the
face of such new Debenture, the Principal that remains outstanding (or in the
case of a new Debenture being issued pursuant to Section 6(a) or Section 6(c),
the Principal designated by the Holder which, when added to the principal
represented by the other new Debentures issued in connection with such issuance,
does not exceed the Principal that remains outstanding under this Debenture
immediately prior to such issuance of new Debentures), (iii) shall have an
issuance date, as indicated on the face of such new Debenture, which is the same
as the Issuance Date of this Debenture, (iv) shall have the same rights and
conditions as this Debenture, and (v) shall represent accrued and unpaid
Interest from the Issuance Date.

     

    (7)           NOTICES.  
Any notices, consents, waivers or other communications required or permitted to
be given under the terms hereof must be in writing and will be deemed to have
been delivered:  (i) upon receipt, when delivered personally; (ii)
upon receipt, when sent by facsimile (provided confirmation of transmission is
mechanically or electronically generated and kept on file by the sending party);
or (iii) one (1) Trading Day after deposit with a nationally recognized
overnight delivery service, in each case properly addressed to the party to
receive the same.  The addresses and facsimile numbers for such
communications shall be:

waiver by the Holder of a breach of any provision of this Debenture 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 Debenture. The failure of the
Holder to insist upon strict adherence to any term of this Debenture on one or
more occasions shall not be considered a waiver or deprive that party of the
right thereafter to insist upon strict adherence to that term or any other term
of this Debenture. Any waiver must be in writing.

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 shall violate applicable
laws governing usury, the applicable rate of interest due hereunder shall
automatically be lowered to equal the maximum permitted rate of interest. The
Company covenants (to the extent that it may lawfully do so) that it shall not
at any time insist upon, plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay, extension or usury law or other law which
would prohibit or forgive the Company from paying all or any portion of the
principal of or interest on this Debenture as contemplated herein, wherever
enacted, now or at any time hereafter in force, or which may affect the
covenants or the performance of this indenture, and the Company (to the extent
it may lawfully do so) hereby expressly waives all benefits or advantage of any
such law, and covenants that it will not, by resort to any such law, hinder,
delay or impeded the execution of any power herein granted to the Holder, but
will suffer and permit the execution of every such as though no such law has
been enacted.
