Second Amendment of Securities Purchase Agreement

 EXHIBIT 10.1 
 SECOND AMENDMENT OF SECURITIES PURCHASE AGREEMENT AND SERIES B UNIT PURCHASE WARRANT 
 The Securities
Purchase Agreement dated April 29, 2008 between Cell Therapeutics, Inc. (the “Company”) and BAM Opportunity Fund LP (the “Holder”) and the Series B Unit Purchase Warrant dated April 30, 2008, each as previously amended
to date, are hereby amended as follows, as of July 23, 2008. 
 WHEREAS, Section 1.1 of such Securities Purchase Agreement (as
amended to date) provides in relevant part: 
 “Series B Convertible Notes” means the 15% Series B
Convertible Notes of the Company to be issued under a Trust Indenture between the Company and US Bank National Association as Trustee, and of like tenor as the Convertible Notes except for the different issuance date, the absence of an optional
redemption right, a 3-year term, a 15% annual interest rate, and a make-whole provision based on the 3-year term and the 15% annual interest rate. 
 WHEREAS, the Holder is not now obligated to exercise any further amount of the Series B Unit Purchase Warrant, but is willing to exercise $22,250,000 of the remaining $44,500,000 of the Series B Unit Purchase Warrant forthwith and the other
$22,250,000 approximately four weeks after the date of this Amendment—each upon, but only upon, the terms provided for herein. 
 WHEREAS, the Company wishes to induce such two exercises of the Series B Unit Purchase Warrant by the Holder. 
 WHEREAS, the
parties have satisfied themselves that Rodman & Renshaw has agreed that its fee for such two exercises of the Series B Unit Purchase Warrant by the Holder will be limited to $300,000 per exercise. 
 WHEREAS, the parties wish to amend the Series B Unit Purchase Warrant to increase the maximum number of Units purchasable thereunder should the parties
mutually agree hereafter to such a further purchase. 
 NOW, THEREFORE, in consideration of the foregoing, the parties agree as follows:

 1. Notwithstanding anything in the Securities Purchase Agreement and the Series B Unit Purchase Warrants to the contrary, the Securities
Purchase Agreement and the Series B Unit Purchase Warrants are amended to provide that all references therein to Series B Convertible Notes or 12.50% Series B Convertible Notes [for avoidance of doubt: the parties confirm such references were
previously amended to mean 15% notes] shall, instead of the meaning quoted in the Recitals above, have (as to all such notes issued after the execution of this Amendment) the following meaning: 
 “18.33% Series B Convertible Senior Notes of the Company to be issued under a Trust Indenture between the Company and US Bank
National Association as Trustee, and of like tenor as the Convertible Notes except for the different issuance date, the absence of an optional redemption right, a 3-year term, a 18.33% annual interest rate, and a make-whole provision based on the
3-year term and the 18.33% annual interest rate.” 
 2. The Holder agrees to exercise the Series B Unit Purchase Warrant to the extent
of $22,250,000 of the remaining $44,500,000 by no later than July 25, 2008, and to the extent of an additional $22,250,000 by no later than August 25, 2008. In order to induce these exercises, the Company shall (in addition to providing,
upon each such respective exercise, the 18.33% Convertible Senior Notes due 2011 and 14,082,278 Series A Warrants [50% warrant coverage] as contemplated by the Series B Unit Purchase Warrant, except that such Series A Warrants shall have an exercise
price of $0.79 per share), amend the 17,468,354 Series A Warrants (the “Amended Warrants”) initially associated with the $27,600,000 principal amount of 13.5% Convertible Senior Notes due 2014 of the Company (“13.5% Notes”) which
has been, before the date of this Amendment, converted by the Holder into Common Stock pursuant to the terms of such 13.5% Notes, so that such Amended Warrants shall have an exercise price of $0.79 per share. 

 3. In addition, effective immediately upon exercise of the Series B Unit Purchase Warrant
to the extent of $22,250,000 of the remaining $44,500,000, the Company shall repurchase from the Holder, for $8,759,000 cash to be paid at the time specified below in this Paragraph 3, an $8,759,000-principal-amount portion (the “Repurchased
Notes”) of the 13.5% Notes now held by the Holder together with the 5,506,329 Series A Warrants initially associated with the particular Repurchased Notes (the “Repurchased Warrants”). The Holder shall deliver the Repurchased Notes
and Repurchased Warrants to the Company free and clear of all liens, adverse claims and encumbrances. The parties agree and acknowledge that in connection with the repurchase of the Repurchased Notes and Repurchased Warrants the Company shall be
entitled to receive from escrow and retain $3,262,500 of the “make-whole” payments associated with the Repurchased Notes and the Holder shall be entitled (from escrow and not from any other source) to $3,787,348 of the
“make-whole” payments associated with the Repurchased Notes; and the Holder agrees to cooperate with the Company’s efforts to procure the release from escrow to the Company of $3,262,500 of the “make-whole” payments
associated with the Repurchased Notes. The parties acknowledge that this allocation has been negotiated between the Company and the Holder to provide to the Holder a portion, but only a portion, of the “make-whole” payments associated with
the Repurchased Notes to which the Holder could otherwise have been entitled. The $8,759,000 repurchase price shall be payable forthwith after the Company receives the release from escrow of such $3,262,500 of the “make-whole” payments
associated with the Repurchased Notes. 
 4. In addition, effective immediately upon exercise of the Series B Unit Purchase
Warrant to the extent of the second $22,250,000, the Company shall repurchase from the Holder, for $8,759,000 cash to be paid at the time specified below in this Paragraph 4, a second $8,759,000-principal-amount portion (the “Second Repurchased
Notes”) of the 13.5% Notes now held by the Holder together with the 5,506,329 Series A Warrants initially associated with the particular Second Repurchased Notes (the “Second Repurchased Warrants”). The Holder shall deliver the Second
Repurchased Notes and Second Repurchased Warrants to the Company free and clear of all liens, adverse claims and encumbrances. The parties agree and acknowledge that in connection with the repurchase of the Second Repurchased Notes and Second
Repurchased Warrants the Company shall be entitled to receive and retain $3,262,500 of the “make-whole” payments associated with the Second Repurchased Notes and the Holder shall be entitled (from escrow and not from any other source) to
$3,787,348 of the “make-whole” payments associated with the Second Repurchased Notes; and the Holder agrees to cooperate with the Company’s efforts to procure the release from escrow to the Company of $3,262,500 of the
“make-whole” payments associated with the Second Repurchased Notes. The parties acknowledge that this allocation has been negotiated between the Company and the Holder to provide to the Holder a portion, but only a portion, of the
“make-whole” payments associated with the Second Repurchased Notes to which the Holder could otherwise have been entitled. The $8,759,000 repurchase price shall be payable forthwith after the Company receives the release from escrow of
such $3,262,500 of the “make-whole” payments associated with the Second Repurchased Notes. 
 5. For avoidance of
doubt: the Holder shall not be entitled to receive any interest earned on the “make-whole” payments escrow. 
 6.
Effective 15 days after the Company submits to Nasdaq a Listing of Additional Shares application with respect thereto (unless Nasdaq has earlier indicated its objection thereto, in which case such amendment shall be effective only if and when Nasdaq
approves such Listing of Additional Shares application with respect thereto), the Series B Unit Purchase Warrant is amended to (a) change the number of Units in the preamble thereof from 67,500 to 112,000, and (b) provide that
notwithstanding anything in the Series B Unit Purchase Warrant to the contrary, (i) such additional 44,500 Units (or any portion thereof) shall be purchased if and only if both parties hereafter mutually agree to the particular purchase, and
not otherwise, and (ii) the Company shall not be required to register under the Securities Act and/or reserve for issuance any common stock or other securities underlying such additional 44,500 Units (or any portion thereof) unless and until
and to the extent that such additional 44,500 Units (or the applicable portion thereof) are actually purchased and issued. The Company agrees to submit such Listing of Additional 

  

 2 

 
Shares application forthwith and to use all reasonable efforts to resolve any Nasdaq objections thereto. For avoidance of doubt: upon the effectiveness of
such amendment described in this Paragraph 6, the Series B Unit Purchase Warrant would cover an additional 44,500 Units, with an aggregate purchase price of $44,500,000, and subject to all the other terms and conditions of the Series B Unit Purchase
Warrant (as previously amended to date and as further amended herein). 
 7. Except as expressly set forth in this Amendment, the Securities
Purchase Agreement and the Series B Unit Purchase Warrant (as previously amended to date), and the Amended Warrants, remain unchanged and in full force and effect.

1.1          Purchase
Agreement.  This Note has been executed and delivered pursuant
to the Note and Warrant Purchase Agreement, dated as of July 16, 2008 (the
“Purchase
Agreement”), by and among the Maker, the Holder and the other parties
named therein.  Capitalized terms used and not otherwise defined
herein shall have the meanings set forth for such terms in the Purchase
Agreement.

     

    Section
1.2          ­Interest.  This
Note is issued as an original issue discount obligation reflecting an interest
rate of 12%, and all references to the principal amount hereof shall mean and
refer to the stated value of this Note ($_______), as the same may be reduced
pursuant to conversions and redemptions in accordance with the terms
hereof.  Upon the occurrence of an Event of Default (as defined in
Section 2.1 hereof), the Maker will pay interest to the Holder, payable on

of eighteen percent (18%) and the maximum applicable legal rate per annum,
calculated based on a 360-day year. The payment of any
prepayment, repayment or redemption fee hereunder (whether on maturity or
otherwise) represents compensation for the termination of the conversion option
contained herein, the value of which the Maker acknowledges.

Prepayment.   The principal amount hereof shall be paid in

reborrowed.  The Maker may not prepay any portion of the principal
amount of this Note without the prior written consent of the Holder, which may
be withheld in the Holder’s sole and absolute discretion, except as set forth
below in this Section 1.3 and as set forth in Section 3.6(k)
hereof.

Issuer may prepay this Note in full by making payment of the principal amount
due under the Note, plus a redemption fee of 30% of the principal amount hereof,
at any time without notice;

    

    (ii)           If
Holder provides the Issuer notice of its intent to convert any portion of this
Note during the Initial Period, in lieu thereof, the Issuer may elect to prepay
the full principal amount of the Note, together with payment of a redemption fee
of 30% of the principal amount hereof, by providing Holder three days notice of
its intent to prepay the Note in full.  The Issuer shall then have ten
business days to pay the Note together with the redemption fee in
full.

    

    (b)           From
the end of the Initial Period through the Maturity Date, Issuer may prepay the
principal amount due the Note, plus a redemption fee of 30% of the principal
amount hereof, at any time by giving the Holder ten business days
notice.  Upon receipt of Issuer’s intent to prepay the Note, in lieu
thereof, the Holder may elect to convert the Note as provided in Section 3.6(k)
of this Note.

on the one hand, and the Holder and the Other Holders, on the other
hand.

     

    Section
1.5          Payment on Non-Business

Saturday, Sunday or a public holiday under the laws of the State of New York,
such payment may be due on the next succeeding Business Day and such next
succeeding day shall be included in the calculation of the amount of accrued
interest payable on such date.

     

    Section
1.6          Transfer.  Subject
to the prior written consent of Maker, which consent will not be unreasonably
withheld, this Note may be transferred or sold, subject to the provisions of

security by the Holder; provided, however, that any transfer or sale of this
Note must be in compliance with all applicable securities laws.

accrued hereon, plus fees and expenses, due and payable pursuant to Section
3.6(a) hereof, and thereupon, the same shall be accelerated and so due and
payable, without presentment, demand, protest, or notice, all of which are
hereby expressly unconditionally and irrevocably waived by the Maker; provided, however, that upon
the occurrence of an Event of Default described in Sections 2.1 (j) or (k)

the Holder’s rights, powers, privileges, remedies and interests under this Note,
the Purchase Agreement or applicable law.  No course of delay on the

right of the Holder.  No remedy conferred hereby shall be exclusive of
any other remedy referred to herein or now or hereafter available at law, in
equity, by statute or otherwise.  Upon and after an Event of Default,
this Note shall bear interest at the default rate set forth in Section 1.2

Option.  At any time and from time to time on or after the
Issuance Date, this Note shall be convertible (in whole or in part), at the
option of the Holder (the “Conversion Option”),
into such number of fully paid and non-assessable shares of Common Stock (the
“Conversion
Rate”) as is determined by dividing (x) that portion of the outstanding
principal balance plus any accrued but unpaid interest under this Note as of
such date that the Holder elects to convert by (y) the Conversion Price (as
defined in Section 3.2 hereof) then in effect on the date on which the Holder
faxes a notice of conversion (the “Conversion Notice”),
duly executed, to the Maker (facsimile number: (604) 606-7980,
Attn.: Grant
Atkins) (the “Voluntary Conversion
Date”), provided, however, that the Conversion Price shall be subject to
adjustment as described in Section 3.5 below.  The Holder shall
deliver this Note to the Maker at the address designated in the Purchase
Agreement at such time that this Note is fully converted.  With
respect to partial conversions of this Note, the Maker shall keep written
records of the amount of this Note converted as of each Conversion
Date.

    Section
3.2           Conversion Price.  The term
“Conversion Price” shall mean $.51, subject to adjustment under Section 3.5
hereof (the “Set Price”); provided, that, at any time and from time to time
after January 16, 2009, the Conversion Price shall equal the lesser of the then
effective Set Price and seventy percent (70%) of the average of the five lowest
Closing Bid Prices for the ten (10) preceding Trading Days.

     

    
      Section
3.3          Mechanics of
Conversion.

    

     

    (a)           Not
later than three (3) Trading Days after any Conversion Date, the Maker or its
designated transfer agent, as applicable, shall issue and deliver to the
Depository Trust Company (“DTC”) account on the
Holder’s behalf via the Deposit Withdrawal Agent Commission System (“DWAC”) as specified
in the Conversion Notice, 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.  In the alternative, not later than three (3) Trading Days
after any Conversion Date, the Maker shall deliver to the applicable Holder by
express courier a certificate or certificates which shall be free of restrictive
legends and trading restrictions (other than those required by Section 5.1 of
the Purchase Agreement) representing
the number of shares of Common Stock being acquired upon the conversion of this
Note (the “Delivery
Date”).  Notwithstanding the foregoing to the contrary, the
Maker or its transfer agent shall only be obligated to issue and deliver the
shares to the DTC on the Holder’s behalf via DWAC (or certificates free of
restrictive legends) if such conversion is in connection with a sale and the
Holder has complied with the applicable prospectus delivery requirements (as
evidenced by documentation furnished to and reasonably satisfactory to the
Maker) or such shares may be sold pursuant to Rule 144 or other exemption under
the Securities Act.  If in the case of any Conversion Notice such
certificate or certificates are not delivered to or as directed by the
applicable Holder by the Delivery Date, the Holder shall be entitled by written
notice to the Maker at any time on or before its receipt of such certificate or
certificates thereafter, to rescind such conversion, in which event the Maker
shall immediately return this Note tendered for conversion, whereupon the Maker
and the Holder shall each be restored to their respective positions immediately
prior to the delivery of such notice of revocation, except that any amounts
described in Sections 3.3(b) and (c) shall be payable through the date notice of
rescission is given to the Maker.

     

    (b)           The
Maker understands that a delay in the delivery of the shares of Common Stock
upon conversion of this Note beyond the Delivery Date could result in economic
loss to the Holder.  If the Maker fails to deliver to the Holder such
shares via DWAC (or, if applicable, certificates) by the Delivery Date, the
Maker shall pay to such Holder, in cash, an amount per Trading Day for each
Trading Day until such shares are delivered via DWAC or certificates are
delivered (if applicable), together with interest on such amount at a rate of
10% per annum, accruing until such amount and any accrued interest thereon is
paid in full, equal to the greater of (A) (i) 1% of the aggregate principal
amount of the Notes requested to be converted for the first five (5) Trading
Days after the Delivery Date and (ii) 2% of the aggregate principal amount of
the Notes requested to be converted for each Trading Day thereafter and (B)
$2,000 per day (which amount shall be paid as liquidated damages and not as a
penalty).  Nothing herein shall limit a Holder’s right to pursue
actual damages for the Maker’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).  Notwithstanding anything to the contrary
contained herein, the Holder shall be entitled to withdraw a Conversion Notice,
and upon such withdrawal the Maker shall only be obligated to pay the liquidated
damages accrued in accordance with this Section 3.3(b) through the date the
Conversion Notice is withdrawn.

    (c)           In
addition to any other rights available to the Holder, if the Maker fails to
cause its transfer agent to transmit via DWAC or transmit to the Holder a
certificate or certificates representing the shares of Common Stock issuable
upon conversion of this Note on or before the Delivery Date, and if after such
date the Holder is required by its broker to purchase (in an open market
transaction or otherwise) shares of Common Stock to deliver in satisfaction of a
sale by the Holder of the shares of Common Stock issuable upon conversion of
this Note which the Holder anticipated receiving upon such conversion (a “Buy-In”), then the
Maker shall (1) pay in cash to the Holder the amount by which (x) the Holder’s
total purchase price (including brokerage commissions, if any) for the shares of
Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the
number of shares of Common Stock issuable upon conversion of this Note that the
Maker was required to deliver to the Holder in connection with the conversion at
issue times (B) the price at which the sell order giving rise to such purchase
obligation was executed, and (2) at the option of the Holder, either reinstate
the portion of the Note and equivalent number of shares of Common Stock for
which such conversion was not honored or deliver to the Holder the number of
shares of Common Stock that would have been issued had the Maker timely complied
with its conversion and delivery obligations hereunder.  For example,
if the Holder purchases Common Stock having a total purchase price of $11,000 to
cover a Buy-In with respect to an attempted conversion of shares of Common Stock
with an aggregate sale price giving rise to such purchase obligation of $10,000,
under clause (1) of the immediately preceding sentence the Maker shall be
required to pay the Holder $1,000. The Holder shall provide the Maker written
notice indicating the amounts payable to the Holder in respect of the Buy-In,
together with applicable confirmations and other evidence reasonably requested
by the Maker.  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 Maker’s failure to timely deliver certificates representing
shares of Common Stock upon conversion of this Note as required pursuant to the
terms hereof.

     

    
      Section
3.4           Ownership Cap and Certain
Conversion Restrictions.

    

     

    (a)           Notwithstanding
anything to the contrary set forth in Section 3 of this Note, at no time may the
Holder convert all or a portion of this Note if the number of shares of Common
Stock to be issued pursuant to such conversion, when aggregated with all other
shares of Common Stock owned by the Holder at such time, would result in the
Holder beneficially owning (as determined in accordance with Section 13(d) of
the Exchange Act and the rules thereunder) in excess of 9.99% of the then issued
and outstanding shares of Common Stock outstanding at such time; provided, however, that upon
the Holder providing the Maker with 61 days’ prior written notice that the
Holder would like to waive Section 3.4(a) of this Note with regard to any or all
shares of Common Stock issuable upon conversion of this Note, this Section
3.4(a) shall be of no force or effect with regard to all or a portion of the
Note referenced in the Waiver Notice.

    Section
3.5           Adjustment of Conversion
Price.

    (a)           Until
the Note has been paid in full or converted in full, the Set Price shall be
subject to adjustment from time to time as follows (but shall not be increased,
other than pursuant to Section 3.5(a)(i) hereof):

     

    (i)           Adjustments for Stock Splits
and Combinations.  If the Maker shall at any time or from time
to time after the Issuance Date, effect a stock split of the outstanding Common
Stock, the applicable Set Price in effect immediately prior to the stock split
shall be proportionately decreased.  If the Maker shall at any time or
from time to time after the Issuance Date, combine the outstanding shares of
Common Stock, the applicable Set Price in effect immediately prior to the
combination shall be proportionately increased.  Any adjustments under
this Section 3.5(a)(i) shall be effective at the close of business on the date
the stock split or combination occurs.

     

    (ii)          Adjustments for Certain
Dividends and Distributions.  If the Maker shall at any time or
from time to time after the Issuance Date, make or become irrevocably obligated
to issue the holders of Common Stock a dividend or other distribution payable in
shares of Common Stock, then, and in each event, the applicable Set Price in
effect immediately prior to such event shall be decreased as of the time of such
issuance or, in the event a record date shall have been fixed, as of the close
of business on such record date, by multiplying, the applicable Set Price then
in effect by a fraction:

     

    (1)           the
numerator of which shall be the total number of shares of Common Stock issued
and outstanding immediately prior to the time of such issuance or the close of
business on such record date; and

     

    (2)           the
denominator of which shall be the total number of shares of Common Stock issued
and outstanding immediately prior to the time of such issuance or the close of
business on such record date plus the number of shares of Common Stock issuable
in payment of such dividend or distribution.

     

    (iii)         Adjustment for Other
Dividends and Distributions.  If the Maker shall at any time or
from time to time after the Issuance Date, make or become irrevocably obligated
to issue the holders of its Common Stock a dividend or other distribution
payable in other than shares of Common Stock, then, and in each event, an
appropriate revision to the applicable Set Price shall be made and provision
shall be made (by adjustments of the Set Price or otherwise) so that the holders
of this Note shall receive upon conversions thereof, in addition to the number
of shares of Common Stock receivable thereon, the number of securities of the
Maker or other issuer (as applicable) which they would have received had this
Note been converted into Common Stock on the date of such event and had
thereafter, during the period from the date of such event to and including the
Conversion Date, retained such securities (together with any distributions
payable thereon during such period), giving application to all adjustments
called for during such period under this Section 3.5(a)(iii) with respect to the
rights of the holders of this Note; provided, however, that if a
record date shall have been fixed and such dividend is not fully paid or if such
distribution is not fully made on the date fixed therefor, the Set Price shall
be adjusted pursuant to this paragraph as of the time of actual payment of such
dividends or distributions.

     

    
      
         

      

      
        9

        
          

        

      

      
         

      

    

     

     

    (iv)         Adjustments for
Reclassification, Exchange or Substitution.  If the Common
Stock issuable upon conversion of this Note at any time or from time to time
after the Issuance Date shall be changed to the same or different number of
shares of any class or classes of stock, whether by reclassification, exchange,
substitution or otherwise (other than by way of a stock split or combination of
shares or stock dividends provided for in Sections 3.5(a)(i), (ii) and (iii), or
a reorganization, merger, consolidation, or sale of assets provided for in
Section 3.5(a)(v)), then, and in each event, an appropriate revision to the Set
Price shall be made and provisions shall be made (by adjustments of the Set
Price or otherwise) so that the Holder shall have the right thereafter to
convert this Note into the kind and amount of shares of stock and other
securities receivable upon reclassification, exchange, substitution or other
change, by holders of the number of shares of Common Stock into which such Note
might have been converted immediately prior to such reclassification, exchange,
substitution or other change, all subject to further adjustment as provided
herein.

     

    (v)          Adjustments for
Reorganization, Merger, Consolidation or Sales of Assets.  If
at any time or from time to time after the Issuance Date there shall be a
capital reorganization of the Maker (other than by way of a stock split or
combination of shares or stock dividends or distributions provided for in
Section 3.5(a)(i), (ii) and (iii), or a reclassification, exchange or
substitution of shares provided for in Section 3.5(a)(iv)), or a merger or
consolidation of the Maker with or into another Person where the holders of
outstanding voting securities prior to such merger or consolidation do not own
over fifty percent (50%) of the outstanding voting securities of the merged or
consolidated entity, immediately after such merger or consolidation, or the sale
of all or substantially all of the Maker’s properties or assets to any other
Person (an “Organic
Change”), then as a part of such Organic Change, (A) if the surviving
entity in any such Organic Change is a public company the traded equity
securities of which are registered pursuant to the Securities Exchange Act of
1934, as amended, and such securities are listed or quoted on a national
securities exchange (as defined in the Securities Exchange Act of 1934) or the
OTC Bulletin Board, an appropriate revision to the Set Price shall be made and
provision shall be made (by adjustments of the Set Price or otherwise) so that
the Holder shall have the right thereafter to convert such Note into the kind
and amount of shares of stock and other securities or property of the Maker or
any successor corporation resulting from Organic Change, and (B) if the
surviving entity in any such Organic Change is not such a public company, or its
equity securities are not listed or quoted on a national securities exchange or
the OTC Bulletin Board, the Holder shall have the right to demand prepayment
pursuant to Section 3.6(b) hereof.  In any such case, appropriate
adjustment shall be made in the application of the provisions of this Section
3.5(a)(v) with respect to the rights of the Holder after the Organic Change to
the end that the provisions of this Section 3.5(a)(v) (including any adjustment
in the applicable Set Price then in effect and the number of shares of stock or
other securities deliverable upon conversion of this Note) shall be applied
after that event in as nearly an equivalent manner as may be
practicable.

     

    (vi)         Adjustments for Issuance of
Additional Shares of Common Stock; Below Market Price Issuances. In the
event the Maker, shall, at any time, from time to time, issue or sell any
additional shares of common stock (otherwise than as provided  in the
foregoing subsections (i) through (v) of this Section 3.5(a)) (“Additional Shares of Common
Stock”), at a price per share less than the Conversion Price then in
effect or without consideration, then the Set Price upon each such issuance
shall be reduced to a price equal to the consideration per share paid for such
Additional Shares of Common Stock.  If the Maker shall issue Common
Stock or rights, options or warrants entitling the recipient or holder thereof
to subscribe for or purchase shares of Common Stock at a price per share less
than the VWAP on the date of issuance, but higher than the Set Price then in
effect, the Set Price shall be multiplied by a fraction, of which the
denominator shall be the number of shares of the Common Stock outstanding on the
date of issuance of such Common Stock or rights or warrants plus the number of
additional shares of Common Stock offered for subscription or purchase, and of
which the numerator shall be the number of shares of the Common Stock
outstanding on the date of issuance of such rights or warrants plus the number
of shares which the aggregate offering price of the total number of shares so
offered (assuming receipt by the Maker in full of all consideration payable upon
exercise of such rights, options or warrants) would purchase at such
VWAP.  Such adjustment shall be made whenever such securities are
issued, and shall become effective immediately after the record date (if
applicable) for the determination of stockholders entitled to receive such
rights, options or warrants.

     

    
      
         

      

      
        10

        
          

        

      

      
         

      

    

     

    (vii)        Issuance of Common Stock
Equivalents.  The provisions of this Section 3.5(a)(vii) shall
apply if (a) the Maker, at any time after the Issuance Date, shall issue any
securities convertible into or exchangeable for, directly or indirectly, Common
Stock (“Convertible
Securities”), or (b) any rights or warrants or options to purchase any
such Common Stock or Convertible Securities (collectively, the “Common Stock
Equivalents”) shall be issued or sold.  If the price per share
for which Additional Shares of Common Stock may be issuable pursuant to any such
Common Stock Equivalent shall be less than the applicable Set Price then in
effect, or if, after any such issuance of Common Stock Equivalents, the price
per share for which Additional Shares of Common Stock may be issuable thereafter
is amended or adjusted, and such price as so amended shall be less than the
applicable Set Price in effect at the time of such amendment or adjustment, then
the applicable Set Price upon each such issuance or amendment shall be adjusted
as provided in the first sentence of subsection (vi) of this Section
3.5(a).

     

    (viii)       Consideration for
Stock.  In case any shares of Common Stock or any Common Stock
Equivalents shall be issued or sold:

     

    (1)           in
connection with any merger or consolidation in which the Maker is the surviving
corporation (other than any consolidation or merger in which the previously
outstanding shares of Common Stock of the Maker shall be changed to or exchanged
for the stock or other securities of another corporation), the amount of
consideration therefor shall be, deemed to be the fair value, as determined
reasonably and in good faith by the Board of Directors of the Maker, of such
portion of the assets and business of the nonsurviving corporation as such Board
may determine to be attributable to such shares of Common Stock, Convertible
Securities, rights or warrants or options, as the case may be; or

     

    (2)           in
the event of any consolidation or merger of the Maker in which the Maker is not
the surviving corporation or in which the previously outstanding shares of
Common Stock of the Maker shall be changed into or exchanged for the stock or
other securities of another corporation, or in the event of any sale of all or
substantially all of the assets of the Maker for stock or other securities of
any corporation, the Maker shall be deemed to have issued a number of shares of
its Common Stock for stock or securities or other property of the other
corporation computed on the basis of the actual exchange ratio on which the
transaction was predicated, and for a consideration equal to the fair market
value on the date of such transaction of all such stock or securities or other
property of the other corporation.  If any such calculation results in
adjustment of the applicable Conversion Price, or the number of shares of Common
Stock issuable upon conversion of the Notes, the determination of the applicable
Conversion Price or the number of shares of Common Stock issuable upon
conversion of the Notes immediately prior to such merger, consolidation or sale,
shall be made after giving effect to such adjustment of the number of shares of
Common Stock issuable upon conversion of the Notes.  In the event
Common Stock is issued with other shares or securities or other assets of the
Maker for consideration which covers both, the consideration computed as
provided in this Section 3.5(a)(viii) shall be allocated among such securities
and assets as determined in good faith by the Board of Directors of the Maker;
or

     

    
      
         

      

      
        11

        
          

        

      

      
         

      

    

     

    (3)          
except in the circumstances described in subsections (1) and (2) above, for any
non-cash consideration, the value of the consideration other than cash received
by the Maker shall be deemed to be the fair market value of such consideration,
as determined reasonably and in good faith by the Maker’s Board of Directors and
deemed to be acceptable by the Holder.

    

    (b)           Record
Date.  In case the Maker shall take record of the holders of
its Common Stock for the purpose of entitling them to subscribe for or purchase
Common Stock or Convertible Securities, then the date of the issue or sale of
the shares of Common Stock shall be deemed to be such record date.

     

    (c)           Certain Issues
Excepted.  Anything herein to the contrary notwithstanding, the
Maker shall not be required to make any adjustment to the Set Price in
connection with the following: (a) issuances of options to employees, officers
or directors of the Maker pursuant to any compensatory stock option plan
existing on the date hereof (and not amended to increase the shares available
thereunder) if such grants were duly approved by a majority of the non-employee
members of the Board of Directors of the Maker or a majority of the members of a
committee of non-employee directors established for such purpose and such
options have an exercise price in excess of the Closing Bid Price on the date of
grant; (b) the issuance of stock grants or stock bonuses to employees, officers
or directors of the Maker pursuant to any compensatory stock option plan
existing on the date hereof (and not amended to increase the shares available
thereunder) if such issuances were duly approved by a majority of the
non-employee members of the Board of Directors of the Maker or a majority of the
members of a committee of non-employee directors established for such purpose;
(c) issuances of securities upon the exercise or exchange of or conversion of
any securities issued hereunder and/or securities exercisable or exchangeable
for or convertible into shares of Common Stock issued and outstanding on the
Issuance Date, provided that such securities have not been amended since the
Issuance Date to increase the number of such securities or to decrease the
exercise, exchange or conversion price of any such securities; (d) securities
issued pursuant to acquisitions or strategic transactions, provided any such
issuance shall only be to a person which is, itself or through its subsidiaries,
an operating company in a business synergistic with the business of the Maker
and in which the Maker receives benefits in addition to the investment of funds,
but shall not include a transaction in which the Maker is issuing securities
primarily for the purpose of raising capital or to an entity whose primary
business is investing in securities; (e) shares of Common Stock issued upon
conversion of the Note and the Other Notes, the Warrants and the warrants issued
to the Finder on the date hereof as described in the Purchase Agreement; and (f)
shares of Common Stock to be issued pursuant to obligations existing on the date
hereof under the License Agreements (existing and as in effect as of the date
hereof) in an amount not to exceed 300,000 shares.

    
      
         

      

      
        12

        
          

        

      

      
         

      

    

     

    

    (d)           No
Impairment.  The Maker shall not, by amendment of its Articles
of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, 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 to be observed or performed hereunder by the Maker, but will at all
times in good faith, assist in the carrying out of all the provisions of this
Section 3.5 and in the taking of all such action as may be necessary or
appropriate in order to protect the Conversion Rights of the Holder against
impairment.  In the event a Holder shall elect to convert any Notes as
provided herein, the Maker cannot 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, violation of an agreement to which such Holder is a party
or for any reason whatsoever, unless, an injunction from a court, or notice,
restraining and or adjoining conversion of all or of said Notes shall have
issued and the Maker posts a surety bond for the benefit of such Holder in an
amount equal to one hundred fifty percent (150%) of the amount of the Notes the
Holder has elected to convert, which bond shall remain in effect until the
completion of arbitration/litigation of the dispute and the proceeds of which
shall be payable to such Holder (as liquidated damages) in the event it obtains
judgment.

    

    (e)        
   Certificates as to
Adjustments.  Upon occurrence of each adjustment or
readjustment of the Conversion Price or number of shares of Common Stock
issuable upon conversion of this Note pursuant to this Section 3.5, the Maker at
its expense shall promptly compute such adjustment or readjustment in accordance
with the terms hereof and furnish to the Holder a certificate setting forth such
adjustment and readjustment, showing in detail the facts upon which such
adjustment or readjustment is based.  The Maker shall, upon written
request of the Holder, at any time, furnish or cause to be furnished to the
Holder a like certificate setting forth such adjustments and readjustments, the
applicable Conversion Price in effect at the time, and the number of shares of
Common Stock and the amount, if any, of other securities or property which at
the time would be received upon the conversion of this
Note.  Notwithstanding the foregoing, the Maker shall not be obligated
to deliver a certificate unless such certificate would reflect an increase or
decrease of at least one percent (1%) of such adjusted amount.

     

    (f)         
  Issue
Taxes.  The Maker shall pay any and all issue and other taxes,
excluding federal, state or local income taxes, that may be payable in respect
of any issue or delivery of shares of Common Stock on conversion of this Note
pursuant thereto; provided, however, that the
Maker shall not be obligated to pay any transfer taxes resulting from any
transfer requested by the Holder in connection with any such
conversion.

     

    (g)           Fractional
Shares.  No fractional shares of Common Stock shall be issued
upon conversion of this Note.  In lieu of any fractional shares to
which the Holder would otherwise be entitled, the Maker shall pay cash equal to
the product of such fraction multiplied by the average of the Closing Bid Prices
of the Common Stock for the five (5) consecutive Trading Days immediately
preceding the Conversion Date.

     

    
      
         

      

      
        13

        
          

        

      

      
         

      

    

    (h)           Reservation of Common
Stock.  The Maker shall at all times when this Note shall be
outstanding, reserve and keep available out of its authorized but unissued
Common Stock, such number of shares of Common Stock as shall from time to time
be sufficient to effect the conversion of this Note and all interest accrued
thereon; provided that the
number of shares of Common Stock so reserved shall at no time be less than one
hundred fifty percent (150%) of the number of shares of Common Stock for which
this Note and all interest accrued thereon are at any time
convertible.  The Maker shall, from time to time in accordance with
Alberta law, increase the authorized number of shares of Common Stock if at any
time the unissued number of authorized shares shall not be sufficient to satisfy
the Maker’s obligations under this Section 3.5(h).

     

    (i)         
  ­Regulatory
Compliance.  If any shares of Common Stock to be reserved for
the purpose of conversion of this Note or any interest accrued thereon require
registration or listing with or approval of any governmental authority, stock
exchange or other regulatory body under any federal or state law or regulation
or otherwise before such shares may be validly issued or delivered upon
conversion, the Maker shall, at its sole cost and expense, in good faith and as
expeditiously as possible, endeavor to secure such registration, listing or
approval, as the case may be.

portion of this Note at a price equal to one hundred and thirty percent (130%)
of the aggregate principal amount of this Note plus all accrued and unpaid

this Section 3.6(a) shall limit the Holder’s rights under Section 2.2
hereof.

     

    (b)           Prepayment Option Upon Major
Transaction.  In addition to all other rights of the Holder

require the Maker to prepay all or a portion of the Holder’s Notes in cash at a
price equal to the sum of (i) the greater of (A) one hundred and thirty percent
(130%) of the aggregate principal amount of this Note plus all accrued and
unpaid interest (if any) and (B) in the event at such time the Holder is unable
to obtain the benefit of its conversion rights through the conversion of this
Note and resale of the shares of Common Stock issuable upon conversion hereof in
accordance with the terms of this Note and the other Transaction Documents or
the Equity Conditions are not satisfied with respect to all such shares of
Common Stock, the aggregate principal amount of this Note plus all accrued but
unpaid interest hereon, divided by the Conversion Price on (x) the date the
Prepayment Price (as defined below) is demanded or otherwise due or (y) the date
the Major Transaction Prepayment Price is paid in full, whichever is less,
multiplied by the VWAP on (x) the date the Major Transaction Prepayment Price is
demanded or otherwise due, and (y) the date the Major Transaction Prepayment
Price is paid in full, whichever is greater, and (ii) all other amounts, costs,
expenses and liquidated damages due in respect of this Note and the other

shall have the right, at the Holder’s option, to require the Maker to prepay all
or a portion of this Note in cash at a price equal to the sum of (i) the greater
of (A) one hundred and thirty percent (130%) of the aggregate principal amount
of this Note plus all accrued and unpaid interest (if any) and (B) the aggregate

is paid in full, whichever is less, multiplied by the VWAP on (x) the date the
Prepayment Price is demanded or otherwise due, and (y) the date the Prepayment

the “Prepayment
Price”).

    (d)           “Major
Transaction.”  A “Major Transaction”
shall be deemed to have occurred at such time as any of the following
events:

     

    (i)           the
consolidation, merger or other business combination of the Maker with or into
another Person (other than (A) pursuant to a migratory merger effected solely
for the purpose of changing the jurisdiction of incorporation of the Maker or
(B) a consolidation, merger or other business combination in which holders of
the Maker’s voting power immediately prior to the transaction continue after the
transaction to hold, directly or indirectly, the voting power of the surviving
entity or entities necessary to elect a majority of the members of the board of
directors (or their equivalent if other than a corporation) of such entity or
entities).

     

    (ii)          the
sale or transfer of more than fifty percent (50%) of the Maker’s assets (based
on the fair market value as determined in good faith by the Maker’s Board of
Directors) other than inventory in the ordinary course of business in one or a
related series of transactions; or

     

    (iii)         closing
of a purchase, tender or exchange offer made to the holders of more than fifty
percent (50%) of the outstanding shares of Common Stock in which more than fifty
percent (50%) of the outstanding shares of Common Stock were tendered and
accepted.

     

    (f)          “Triggering
Event.”  A “Triggering Event”
shall be deemed to have occurred at such time as any of the following
events:

     

    (i)           the
suspension from listing, without subsequent listing on any one of, or the
failure of the Common Stock to be listed on at least one of the OTC Bulletin
Board, the American Stock Exchange, the Nasdaq Capital Markets, the Nasdaq
Global Market, the Nasdaq Global Select Market or The New York Stock Exchange,
Inc., for a period of five (5) consecutive Trading Days;

     

    (ii)          the
Maker’s notice to any holder of the Notes, including by way of public
announcement, at any time, of its inability to comply (including for any of the
reasons described in Section 3.7) or its intention not to comply with proper
requests for conversion of any Notes into shares of Common Stock;
or

     

    
      
         

      

      
        15

        
          

        

      

      
         

      

    

    (iii)         the
Maker’s failure to comply with a Conversion Notice tendered in accordance with
the provisions of this Note within ten (10) Business Days after the receipt by
the Maker of the Conversion Notice; or

     

    (iv)        the
Maker deregisters its shares of Common Stock under the Securities Exchange Act
of 1934; or

     

    (v)         the
Maker consummates a “going private” transaction and as a result the Common Stock
is no longer registered under Sections 12(b) or 12(g) of the Exchange
Act.

     

    (h)           Mechanics of Prepayment at
Option of Holder Upon Major Transaction.  No sooner than
fifteen (15) days nor later than ten (10) days prior to the consummation of a
Major Transaction, but not prior to the public announcement of such Major
Transaction, the Maker shall deliver written notice thereof via facsimile and
overnight courier (“Notice of Major
Transaction”) to the Holder of this Note.  At any time after
receipt of a Notice of Major Transaction (or, in the event a Notice of Major
Transaction is not delivered at least ten (10) days prior to a Major
Transaction, at any time within ten (10) days prior to a Major Transaction), any
holder of the Notes then outstanding may require the Maker to prepay, effective
immediately prior to the consummation of such Major Transaction, all of the
holder’s Notes then outstanding by delivering written notice thereof via
facsimile and overnight courier (“Notice of Prepayment at
Option of Holder Upon Major Transaction”) to the Maker, which Notice of
Prepayment at Option of Holder Upon Major Transaction shall indicate (i) the
principal amount of the Notes that such holder is electing to have prepaid and
(ii) the applicable Major Transaction Prepayment Price, as calculated pursuant
to Section 3.6(b) above.

     

    (i)           Mechanics of Prepayment at
Option of Holder Upon Triggering Event.  Within one (1)
Business Day after the occurrence of a Triggering Event, the Maker shall deliver
written notice thereof via facsimile and overnight courier (“Notice of Triggering
Event”) to each holder of the Notes.  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, any holder of this Note and Other Notes
then outstanding may require the Maker to prepay all of the Notes on a pro rata
basis by delivering written notice thereof via facsimile and overnight courier
(“Notice of Prepayment
at Option of Holder Upon Triggering Event”) to the Maker, which Notice of
Prepayment at Option of Holder Upon Triggering Event shall indicate (i) the
amount of the Note that such holder is electing to have prepaid and (ii) the
applicable Triggering Event Prepayment Price, as calculated pursuant to Section
3.6(c) above.  A holder shall only be permitted to require the Maker
to prepay the Note pursuant to Section 3.6 hereof for the greater of a period of
ten (10) days after receipt by such holder of a Notice of Triggering Event or
for so long as such Triggering Event is continuing.

    (j)          
 Payment of
Prepayment Price.  Upon the Maker’s receipt of a Notice(s) of
Prepayment at Option of Holder Upon Triggering Event or a Notice(s) of
Prepayment at Option of Holder Upon Major Transaction from any holder of the
Notes, the Maker shall immediately notify each holder of the Notes by facsimile
of the Maker’s receipt of such Notice(s) of Prepayment at Option of Holder Upon
Triggering Event or Notice(s) of Prepayment at Option of Holder Upon Major
Transaction and each holder which has sent such a notice shall promptly
submit to
the Maker such holder’s certificates representing the Notes which such holder
has elected to have prepaid.  The Maker shall deliver the applicable
Triggering Event Prepayment Price, in the case of a prepayment pursuant to
Section 3.6(i), to such holder within five (5) Business Days after the Maker’s
receipt of a Notice of Prepayment at Option of Holder Upon Triggering Event and,
in the case of a prepayment pursuant to Section 3.6(h), the Maker shall deliver
the applicable Major Transaction Prepayment Price immediately prior to the
consummation of the Major Transaction; provided that a holder’s original Note
shall have been so delivered to the Maker; provided further that if the Maker is
unable to prepay all of the Notes to be prepaid, the Maker shall prepay an
amount from each holder of the Notes being prepaid equal to such holder’s
pro-rata amount (based on the number of Notes and Other Notes held by such
holder relative to the number of Notes and Other Notes outstanding) of all Notes
being prepaid.  If the Maker shall fail to prepay all of the Notes
submitted for prepayment (other than pursuant to a dispute as to the arithmetic
calculation of the Prepayment Price), in addition to any remedy such holder of
the Notes may have under this Note and the Purchase Agreement, the applicable
Prepayment Price payable in respect of such Notes not prepaid shall bear
interest at the rate of two percent (2%) per month (prorated for partial months)
until paid in full.  Until the Maker pays such unpaid applicable
Prepayment Price in full to a holder of the Notes submitted for prepayment, such
holder shall have the option (the “Void Optional Prepayment
Option”) to, in lieu of prepayment, require the Maker to promptly return
to such holder(s) all of the Notes that were submitted for prepayment by such
holder(s) under this Section 3.6 and for which the applicable Prepayment Price
has not been paid, by sending written notice thereof to the Maker via facsimile
(the “Void Optional
Prepayment Notice”).  Upon the Maker’s receipt of such Void
Optional Prepayment Notice(s) and prior to payment of the full applicable
Prepayment Price to such holder, (i) the Notice(s) of Prepayment at Option of
Holder Upon Triggering Event or the Notice(s) of Prepayment at Option of Holder
Upon Major Transaction, as the case may be, shall be null and void with respect
to those Notes submitted for prepayment and for which the applicable Prepayment
Price has not been paid, (ii) the Maker shall immediately return any Notes
submitted to the Maker by each holder for prepayment under this Section 3.6(j)
and for which the applicable Prepayment Price has not been paid and (iii) the
Conversion Price of such returned Notes shall be adjusted to the lesser of (A)
the Conversion Price as in effect on the date on which the Void Optional
Prepayment Notice(s) is delivered to the Maker and (B) the lowest Closing Bid
Price during the period beginning on the date on which the Notice(s) of
Prepayment of Option of Holder Upon Major Transaction or the Notice(s) of
Prepayment at Option of Holder Upon Triggering Event, as the case may be, is
delivered to the Maker and ending on the date on which the Void Optional
Prepayment Notice(s) is delivered to the Maker; provided that no adjustment
shall be made if such adjustment would result in an increase of the Conversion
Price then in effect.  A holder’s delivery of a Void Optional
Prepayment Notice and exercise of its rights following such notice shall not
effect the Maker’s obligations to make any payments which have accrued prior to
the date of such notice.  Payments provided for in this Section 3.6
shall have priority to payments to other stockholders in connection with a Major
Transaction.

    (k)           
Maker Prepayment
Option.  On and after the Initial Period, the Maker may prepay
in cash all (but not less than all) of the outstanding principal amount of this
Note and the Other Notes upon ten (10) days prior written notice to the Holder
and the Other Holders (the “Maker’s Prepayment
Notice”) at a price equal to one hundred and thirty percent (130%) of the
aggregate principal amount of this Note (the “Maker's Prepayment
Price”); provided, however, that if
after the Initial Period, the Holder has delivered a Conversion Notice to the
Maker or delivers a Conversion Notice within such ten (10) day period following
delivery of the Maker’s Prepayment Notice, the principal amount of the Notes
designated to be converted may not be prepaid by the Maker and shall be
converted in accordance with Section 3.3 hereof; provided further that if during
the period between delivery of the Maker's Prepayment Notice and the Maker's
Prepayment Date (as defined below), a holder shall become entitled to deliver a
Notice of Prepayment at Option of Holder Upon Major Transaction or Notice of
Prepayment at Option of Holder upon Triggering Event, then the such rights of
the holders shall take precedence over the previously delivered Maker Prepayment
Notice.  The Maker's Prepayment Notice shall state the date of
prepayment which date shall be the eleventh (11th) day after the Maker has
delivered the Maker's Prepayment Notice (the “Maker's Prepayment
Date”), the Maker’s Prepayment Price and the principal amount of Notes to
be prepaid by the Maker.  The Maker shall deliver the Maker's
Prepayment Price on the Maker’s Prepayment Date, provided, that if the holder(s)
delivers a Conversion Notice before the Maker's Prepayment Date, then the
portion of the Maker's Prepayment Price which would be paid to prepay the Notes
covered by such Conversion Notice shall be returned to the Maker upon delivery
of the Common Stock issuable in connection with such Conversion Notice to the
holder(s).  On the Maker's Prepayment Date, the Maker shall pay the
Maker's Prepayment Price, subject to any adjustment pursuant to the immediately
preceding sentence, to the Holder and the Other Holders.  If the Maker
fails to pay the Maker's Prepayment Price by the eleventh (11th) day after the
Maker has delivered the Maker's Prepayment Notice, the prepayment will be
declared null and void and the Maker shall lose its right to serve a Maker’s
Prepayment Notice pursuant to this Section 3.6(k) in the
future.  Notwithstanding the foregoing to the contrary, the Maker may
effect a prepayment pursuant to this Section 3.6(k) only if (A) trading in the
Common Stock shall not have been suspended by the Securities and Exchange
Commission or the OTC Bulletin Board (or other national securities exchange on
which the Common Stock is trading), (B) the Maker is in material compliance with
the terms and conditions of this Note and the other Transaction Documents, and
(C) the Maker is not in possession of any material non-public
information.  Notwithstanding the above, on or prior to January 16,
2009, (A) the Maker’s Prepayment Notice may be delivered with at least one (1)
day’s prior written notice (provided that the Maker’s Prepayment Price is paid
on the date of prepayment set forth in such notice), (B) Sweetwater Capital
Corporation (“Sweetwater”) shall be permitted to exercise the Maker’s prepayment
option under this Section 3.6(f) if the same shall have been assigned to
Sweetwater by the Maker and the conditions set forth in this Section 3.6(f) are
otherwise fulfilled and (C) the Maker shall be permitted to deliver a Maker’s
Prepayment Notice after delivery of a Conversion Notice, and such conversion
shall be of no force and effect if the Maker delivers the Maker’s Prepayment
Price by the third (3) Trading Day following such Conversion
Notice.

     

    Section
3.7           Inability to Fully
Convert.

     

    (a)           Holder’s Option if Maker
Cannot Fully Convert.  If, upon the Maker’s receipt of a
Conversion Notice, the Maker cannot issue shares of Common Stock for any reason,
including, without limitation, because the Maker (x) does not have a sufficient
number of shares of Common Stock authorized and available, or (y) is otherwise
prohibited by applicable law or by the rules or regulations of any stock
exchange, interdealer quotation system or other self-regulatory organization
with jurisdiction over the Maker or any of its securities from issuing all of
the Common Stock which is to be issued to the Holder pursuant to a Conversion
Notice, then the Maker shall issue as many shares of Common Stock as it is able
to issue in accordance with the Holder’s Conversion Notice and, with respect to
the unconverted portion of this Note, the Holder, solely at Holder’s option, can
elect to:

     

    
      
         

      

      
        18

        
          

        

      

      
         

      

    

     

    (i)           If
the Maker’s inability to fully convert is pursuant to Section 3.7(a)(x) above,
require the Maker to prepay that portion of this Note for which the Maker is
unable to issue Common Stock in accordance with the Holder’s Conversion Notice
(the “Mandatory
Prepayment”) at a price per share equal to the Triggering Event
Prepayment Price as of such Conversion Date (the “Mandatory Prepayment
Price”);

     

    (ii)          if
the Maker’s inability to fully convert is pursuant to Section 3.7(a)(y) above,
require the Maker to issue restricted shares of Common Stock in accordance with
such holder’s Conversion Notice;

     

    (iii)         void
its Conversion Notice and retain or have returned, as the case may be, this Note
that was to be converted pursuant to the Conversion Notice (provided that the
Holder’s voiding its Conversion Notice shall not effect the Maker’s obligations
to make any payments which have accrued prior to the date of such
notice);

     

    (iv)        exercise
its Buy-In rights pursuant to and in accordance with the terms and provisions of
Section 3.3(c) of this Note.

     

    In the
event a Holder shall elect to convert any portion of its Notes as provided
herein, the Maker cannot 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, violation of an agreement to which such Holder is a party or
for any reason whatsoever, unless, an injunction from a court, on notice,
restraining and or adjoining conversion of all or of said Notes shall have been
issued and the Maker posts a surety bond for the benefit of such Holder in an
amount equal to 130% of the principal amount of the Notes the Holder has elected
to convert, which bond shall remain in effect until the completion of
arbitration/litigation of the dispute and the proceeds of which shall be payable
to such Holder in the event it obtains judgment.

    

    (b)           Mechanics of Fulfilling
Holder’s Election.  The Maker shall immediately send via
facsimile to the Holder, upon receipt of a facsimile copy of a Conversion Notice
from the Holder which cannot be fully satisfied as described in Section 3.7(a)
above, a notice of the Maker’s inability to fully satisfy the Conversion Notice
(the “Inability to
Fully Convert Notice”).  Such Inability to Fully Convert Notice
shall indicate (i) the reason why the Maker is unable to fully satisfy such
holder’s Conversion Notice, (ii) the amount of this Note which cannot be
converted and (iii) the applicable Mandatory Prepayment Price.  The
Holder shall notify the Maker of its election pursuant to Section 3.7(a) above
by delivering written notice via facsimile to the Maker (“Notice in Response to
Inability to Convert”).

     

    (c)   
        Payment of Prepayment
Price.  If the Holder shall elect to have its Notes prepaid
pursuant to Section 3.7(a)(i) above, the Maker shall pay the Mandatory
Prepayment Price to the Holder within thirty (30) days of the Maker’s receipt of
the Holder’s Notice in Response to Inability to Convert, provided that prior
to the Maker’s receipt of the Holder’s Notice in Response to Inability to
Convert the Maker has not delivered a notice to the Holder stating, to the
satisfaction of the Holder, that the event or condition resulting in the
Mandatory Prepayment has been cured and all Conversion Shares issuable to the
Holder can and will be delivered to the Holder in accordance with the terms of
this Note.  If the Maker shall fail to pay the applicable Mandatory
Prepayment Price to the Holder on the date that is one (1) Business Day
following the Maker’s receipt of the Holder’s Notice in Response to Inability to
Convert (other than pursuant to a dispute as to the determination of the
arithmetic calculation of the Prepayment Price), in addition to any remedy the
Holder may have under this Note and the Purchase Agreement, such unpaid amount
shall bear interest at the rate of two percent (2%) per month (prorated for
partial months) until paid in full.  Until the full Mandatory
Prepayment Price is paid in full to the Holder, the Holder may (i) void the
Mandatory Prepayment with respect to that portion of the Note for which the full
Mandatory Prepayment Price has not been paid, (ii) receive back such Note, and
(iii) require that the Conversion Price of such returned Note be adjusted to the
lesser of (A) the Conversion Price as in effect on the date on which the Holder
voided the Mandatory Prepayment and (B) the lowest Closing Bid Price during the
period beginning on the Conversion Date and ending on the date the Holder voided
the Mandatory Prepayment.

    (d)           Pro-rata Conversion and
Prepayment.  In the event the Maker receives a Conversion
Notice from more than one holder of the Notes on the same day and the Maker can
convert and prepay some, but not all, of the Notes pursuant to this Section 3.7,
the Maker shall convert and prepay from each holder of the Notes electing to
have its Notes converted and prepaid at such time an amount equal to such
holder’s pro-rata amount (based on the principal amount of the Notes held by
such holder relative to the principal amount of the Notes and
any  Other Notes outstanding) of all the Notes being converted and
prepaid at such time.

     

    Section
3.8           No Rights as
Shareholder.  Nothing contained in this Note shall be construed
as conferring upon the Holder, prior to the conversion of this Note, the right
to vote or to receive dividends or to consent or to receive notice as a
shareholder in respect of any meeting of shareholders for the election of
directors of the Maker or of any other matter, or any other rights as a
shareholder of the Maker.
