1.
            DURATION
      AND EXERCISE OF WARRANTS





(a)           Exercise
Period.  The Holder may exercise this Warrant in whole or in
part on any Business Day on or before 5:00 P.M., Eastern Time, on the Expiration
Date, at which time this Warrant shall become void and of no value.





The
Expiration Date will be March 1, 2013, except that in the event that the
securities sold in any Covered Offering include warrants to purchase the Common
Stock (the “Other
Warrants”) and the period provided to exercise the Other Warrants is
greater than three (3) years, then the exercise period of this Warrant will be
extended to be equal to the exercise period of the Other Warrants





(b)
            Exercise
      Procedures.





(i)          
While this Warrant remains outstanding and exercisable in accordance with
Section 1(a), the Holder may exercise this Warrant in whole or in part at any
time and from time to time by:





(A)          delivery
to the Company of a duly completed and executed copy of the notice of exercise
attached as Exhibit A(the “Notice of
Exercise”);





(B)           surrender
of this Warrant to the Secretary of the Company at its principal offices or at
such other office or agency as the Company may specify in writing to the Holder;
and





(C)           payment
of the then-applicable Exercise Price per share multiplied by the number of
Warrant Shares being purchased upon exercise of the Warrant (such amount, the
“Aggregate Exercise Price”) made in the form
of cash, or by certified check, wire transfer, bank draft or money order payable
in lawful money of the United States of America.


2


(ii)           Upon
the exercise of this Warrant in compliance with the provisions of this Section
1(b), the Company shall promptly issue and cause to be delivered to the Holder a
certificate for the Warrant Shares purchased by the Holder.  Each
exercise of this Warrant shall be effective immediately prior to the close of
business on the date (the “Date
of Exercise”)
that the conditions set forth in Section 1(b) have been satisfied, as the case
may be.  On the first Business Day following the date on which the
Company has received each of this original Warrant, the Notice of Exercise and
the Aggregate Exercise Price (the “Exercise Delivery Documents”),
the Company shall transmit an acknowledgment of receipt of the Exercise Delivery
Documents to the Company’s transfer agent (the “Transfer
Agent”).  On or before the fifth Business Day following the
date on which the Company has received all of the Exercise Delivery Documents
(the “Share Delivery
Date”), the Company shall (X) provided that the Transfer Agent is
participating in The Depository Trust Company (“DTC”) Fast Automated
Securities Transfer Program, upon the request of the Holder, credit such
aggregate number of shares of Common Stock to which the Holder is entitled
pursuant to such exercise 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 dispatch by overnight courier to the address as
specified in the Notice of Exercise, a certificate, registered in the Company’s
share register in the name of the Holder or its designee, for the number of
shares of Common Stock to which the Holder is entitled pursuant to such
exercise.  Upon delivery of the Exercise Delivery Documents, the
Holder shall be deemed for all corporate purposes to have become the holder
of record of the Warrant Shares with respect to which this Warrant has been
exercised, irrespective of the date of delivery of the certificates evidencing
such Warrant Shares.





(iii)          If
the Company shall fail for any reason or for no reason to issue to the Holder,
within five (5) Business Days of receipt of the Exercise Delivery Documents, a
certificate for the number of shares of Common Stock to which the Holder is
entitled and register such shares of Common Stock on the Company’s share
register or to credit the Holder’s balance account with DTC for such number of
shares of Common Stock to which the Holder is entitled upon the Holder’s
exercise of this Warrant, and if on or after such Business Day the Holder
purchases (in an open market transaction or otherwise) shares of Common Stock to
deliver in satisfaction of a sale by the Holder of shares of Common Stock
issuable upon such exercise that the Holder anticipated receiving from the
Company (a “Buy-In”),
then the Company shall, within five (5) Business Days after the Holder’s request
and in the Holder’s discretion, either (X) pay cash to the Holder in an amount
equal to the Holder’s total purchase price (including brokerage commissions, 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 shares
of Common Stock) shall terminate, or (Y) promptly honor its obligation to
deliver to the Holder a certificate or certificates representing such shares of
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 date of exercise.





(c)          Partial
Exercise.  This Warrant shall be exercisable, either in its
entirety or, from time to time, for part only of the number of Warrant Shares
referenced by this Warrant; provided, that any such partial exercise must be for
an integral number of Warrant Shares.  If this Warrant is exercised in
part, the Company shall issue, at its expense, a new Warrant, in substantially
the form of this Warrant, referencing such reduced number of Warrant Shares that
remain subject to this Warrant.


3





(d)         Disputes.  In
the case of a dispute as to the determination of the Exercise Price or the
arithmetic calculation of the Warrant Shares, the Company shall promptly issue
to the Holder the number of Warrant Shares that are not disputed and resolve
such dispute in accordance with Section 15.





2.
            ISSUANCE
      OF WARRANT SHARES





(a)    
     The Company covenants that all Warrant Shares
will, upon issuance in accordance with the terms of this Warrant, be (i) duly
authorized, fully paid and non-assessable, and (ii) free from all liens, charges
and security interests, with the exception of claims arising through the acts or
omissions of any Holder and except as arising from applicable federal and state
securities laws.





(b)          The
Company shall register this Warrant upon records to be maintained by the Company
for that purpose in the name of the record holder of such Warrant from time to
time. The Company may deem and treat the registered Holder of this Warrant as
the absolute owner thereof for the purpose of any exercise thereof, any
distribution to the Holder thereof and for all other purposes.





(c)          The
Company will not, by amendment of its articles of incorporation, by-laws 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 Company, but will at all times in good faith
assist in the carrying out of all the provisions of this Warrant and in the
taking of all action necessary or appropriate in order to protect the rights of
the Holder to exercise this Warrant, or against impairment of such
rights.





3.
            ADJUSTMENTS
      OF EXERCISE PRICE, NUMBER AND TYPE OF WARRANT
  SHARES





(a)          The
Exercise Price and the number of shares purchasable upon the exercise of this
Warrant shall be subject to adjustment from time to time upon the occurrence of
certain events described in this Section 3(a); provided, that
notwithstanding the provisions of this Section 3, the Company shall not be
required to make any adjustment if and to the extent that such adjustment would
require the Company to issue a number of shares of Common Stock in excess of its
authorized but unissued shares of Common Stock, less all amounts of Common Stock
that have been reserved for issue upon the conversion of all outstanding
securities convertible into shares of Common Stock and the exercise of all
outstanding options, warrants and other rights exercisable for shares of Common
Stock.  If the Company does not have the requisite number of
authorized but unissued shares of Common Stock to make any adjustment, the
Company shall use its commercially reasonable efforts to obtain the necessary
stockholder consent to increase the authorized number of shares of Common Stock
to make such an adjustment pursuant to this Section 3(a).


4


(i)           Subdivision or Combination
of Stock. In case the Company shall at any time subdivide (whether by way
of stock dividend, stock split or otherwise) its outstanding shares of Common
Stock into a greater number of shares, the Exercise Price in effect immediately
prior to such subdivision shall be proportionately reduced and the number of
Warrant Shares shall be proportionately increased, and conversely, in case the
outstanding shares of Common Stock of the Company shall be combined (whether by
way of stock combination, reverse stock split or otherwise) into a smaller
number of shares, the Exercise Price in effect immediately prior to such
combination shall be proportionately increased and the number of Warrant Shares
shall be proportionately decreased.  The Exercise Price and the
Warrant Shares, as so adjusted, shall be readjusted in the same manner upon the
happening of any successive event or events described in this Section
3(a)(i).





(ii)          Dividends in Stock, Property,
Reclassification. If at any time, or from time to time, the holders of
Common Stock (or any shares of stock or other securities at the time receivable
upon the exercise of this Warrant) shall have received or become entitled to
receive, without payment therefore:





(A)          any
shares of stock or other securities that are at any time directly or indirectly
convertible into or exchangeable for Common Stock, or any rights or options to
subscribe for, purchase or otherwise acquire any of the foregoing by way of
dividend or other distribution, or





(B)           additional
stock or other securities or property (including cash) by way of spin-off,
split-up, reclassification, combination of shares or similar corporate
rearrangement (other than shares of Common Stock issued as a stock split or
adjustments in respect of which shall be covered by the terms of Section 3(a)(i)
above),





then and
in each such case, the Exercise Price and the number of Warrant Shares to be
obtained upon exercise of this Warrant shall be adjusted proportionately, and
the Holder hereof shall, upon the exercise of this Warrant, be entitled to
receive, in addition to the number of shares of Common Stock receivable
thereupon, and without payment of any additional consideration therefor, the
amount of stock and other securities and property (including cash in the cases
referred to above) that such Holder would hold on the date of such exercise had
such Holder been the holder of record of such Common Stock as of the date on
which holders of Common Stock received or became entitled to receive such shares
or all other additional stock and other securities and property.  The
Exercise Price and the Warrant Shares, as so adjusted, shall be readjusted in
the same manner upon the happening of any successive event or events described
in this Section 3(a)(ii).


5


(iii)          Reorganization,
Reclassification, Consolidation, Merger or Sale. If any recapitalization,
reclassification or reorganization of the capital stock of the Company, or any
consolidation or merger of the Company with another corporation, or the sale of
all or substantially all of its assets or other transaction shall be effected in
such a way that holders of Common Stock shall be entitled to receive stock,
securities or other assets or property (an “Organic Change”), then lawful
and adequate provisions shall be made by the Company whereby the Holder hereof
shall thereafter have the right to purchase and receive (in lieu of the shares
of the Common Stock of the Company immediately theretofore purchasable and
receivable upon the exercise of the rights represented by this Warrant) such
shares of stock, securities or other assets or property as may be issued or
payable with respect to or in exchange for a number of outstanding shares of
such Common Stock equal to the number of shares of such stock immediately
theretofore purchasable and receivable assuming the full exercise of the rights
represented by this Warrant. In the event of any Organic Change, appropriate
provision shall be made by the Company with respect to the rights and interests
of the Holder of this Warrant to the end that the provisions hereof (including,
without limitation, provisions for adjustments of the Exercise Price and of the
number of shares purchasable and receivable upon the exercise of this Warrant)
shall thereafter be applicable, in relation to any shares of stock, securities
or assets thereafter deliverable upon the exercise hereof. To the extent
necessary to effect the foregoing provisions, the successor corporation (if
other than the Company) resulting from such consolidation or merger or the
corporation purchasing such assets shall assume by written instrument reasonably
satisfactory in form and substance to the Holder executed and mailed or
delivered to the registered Holder hereof at the last address of such Holder
appearing on the books of the Company, the obligation to deliver to such Holder
such shares of stock, securities or assets as, in accordance with the foregoing
provisions, such Holder may be entitled to purchase.If there is an Organic
Change, then the Company shall cause to be mailed to the Holder at its last
address as it shall appear on the books and records of the Company, at least 10
calendar days before the effective date of the Organic Change, a notice stating
the date on which such Organic Change is expected to become effective or close,
and the date as of which it is expected that holders of the Common Stock of
record shall be entitled to exchange their shares for securities, cash, or other
property delivered upon such Organic Change; provided, that the
failure to mail such notice or any defect therein or in the mailing thereof
shall not affect the validity of the corporate action required to be specified
in such notice.  The Holder is entitled to exercise this Warrant
during the 10-day period commencing on the date of such notice to the effective
date of the event triggering such notice.  In any event, the successor
corporation (if other than the Company) resulting from such consolidation or
merger or the corporation purchasing such assets shall be deemed to assume such
obligation to deliver to such Holder such shares of stock, securities or assets
even in the absence of a written instrument assuming such obligation to the
extent such assumption occurs by operation of law.





(b)          Certificate as to
Adjustments. Upon the occurrence of each adjustment or readjustment
pursuant to this Section 3, the Company at its expense shall promptly compute
such adjustment or readjustment in accordance with the terms hereof and furnish
to each Holder of this Warrant a certificate setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The Company shall promptly furnish or cause to be
furnished to such Holder a like certificate setting forth: (i) such adjustments
and readjustments; and (ii) the number of shares and the amount, if any, of
other property which at the time would be received upon the exercise of the
Warrant.





(c)          Certain Events. If
any event occurs as to which the other provisions of this Section 3 are not
strictly applicable but the lack of any adjustment would not fairly protect the
purchase rights of the Holder under this Warrant in accordance with the basic
intent and principles of such provisions, or if strictly applicable would not
fairly protect the purchase rights of the Holder under this Warrant in
accordance with the basic intent and principles of such provisions, then the
Company's Board of Directors will, in good faith and subject to applicable law,
make an appropriate adjustment to protect the rights of the Holder; provided, that no
such adjustment pursuant to this Section 3(c) will increase the Exercise Price
or decrease the number of Warrant Shares as otherwise determined pursuant to
this Section 3.


6




(d)         Adjustment of Exercise Price
Upon Issuance of Additional Shares of Common Stock.  In the
event the Company shall at any time prior to the Expiration Date issue
Additional Shares of Common Stock (as defined below) without consideration or
for a consideration per share less than the Exercise Price in effect immediately
prior to such issue, then the Exercise Price shall be reduced, concurrently with
such issue, to a price (calculated to the nearest cent) determined by
multiplying such Exercise Price by a fraction, (A) the numerator of which shall
be (1) the number of shares of Common Stock outstanding immediately prior to
such issue plus (2) the number of shares of Common Stock which the aggregate
consideration received or to be received by the Company for the total number of
Additional Shares of Common Stock so issued would purchase at such Exercise
Price; and (B) the denominator of which shall be the number of shares of Common
Stock outstanding immediately prior to such issue plus the number of such
Additional Shares of Common Stock so issued; provided that, (i)
for the purpose of this Section 3(d), all shares of Common Stock issuable upon
conversion or exchange of convertible securities outstanding immediately prior
to such issue shall be deemed to be outstanding, and (ii) the number of shares
of Common Stock deemed issuable upon conversion or exchange of such outstanding
convertible securities shall be determined without giving effect to any
adjustments to the conversion or exchange price or conversion or exchange rate
of such convertible securities resulting from the issuance of Additional Shares
of Common Stock that is the subject of this calculation.  For purposes
of this Warrant, “Additional Shares of Common Stock” shall mean all shares of
Common Stock issued by the Company after the Effective Date (including without
limitation any shares of Common Stock issuable upon conversion or exchange of
any convertible securities or upon exercise of any option or warrant, on an
as-converted basis), other than: (i) shares of Common Stock issued or
issuable upon conversion or exchange of any convertible securities or exercise
of any options outstanding on the Effective Date; (ii) shares of Common Stock
issued or issuable upon conversion of the warrants issued in connection with the
Offering; (iii) shares of Common Stock issued or issuable by reason of a
dividend, stock split, split-up or other distribution on shares of Common Stock
that is covered by Sections 3(a)(i) through 3(a)(iii) above; (iv) shares of
Common Stock issued in a registered public offering under the Securities Act;
(v) shares of Common Stock issued or issuable pursuant to the acquisition of
another corporation by the Corporation by merger, purchase of substantially all
of the assets or other reorganization or to a joint venture agreement; or
(vi) shares of Common Stock issued or issuable to officers, directors and
employees of, or consultants to, the Company pursuant to stock grants, option
plans, purchase plans or other employee stock incentive programs or arrangements
approved by the Board of Directors, or upon exercise of options or warrants
granted to such parties pursuant to any such plan or arrangement.  The
provisions of this Section 3(d) shall not operate to increase the Exercise
Price.  Whenever the Exercise Price is adjusted pursuant to this
Section 3(d), the number of shares of Common Stock issuable upon exercise of
this Warrant shall be inversely proportionally adjusted such that the aggregate
Exercise Price of this Warrant remains equal immediately before and after any
such adjustment.

case of a dispute as to the determination of the Exercise Price or the
arithmetic calculation of the Warrant Shares, the Company shall submit the
disputed determinations or arithmetic calculations via facsimile within five (5)
Business Days of receipt of the Notice of Exercise giving rise to such dispute,
as the case may be, to the Holder. If the Holder and the Company are unable to
agree upon such determination or calculation of the Exercise Price or the
Warrant Shares within three Business Days of such disputed determination or
arithmetic calculation being submitted to the Holder, then the Company shall, at
its sole discretion, within five (5) Business Days, submit via facsimile (a) the
disputed determination of the Exercise Price to an independent, reputable
investment bank selected by the Company and approved by the Holder, or (b) the
disputed arithmetic calculation of the Warrant Shares to the Company’s
independent, outside accountant. The Company shall cause at its expense the
investment bank or the accountant, as the case may be, to perform the
determinations or calculations and notify the Company and the Holder of the
results no later than ten (10) Business Days from the time it receives the
disputed determinations or calculations; provided that, if such disputed
determination or arithmetic calculation being submitted by the Holder is
determined to be incorrect, then the expense of the investment bank or the
accountant shall be the responsibility of the Holder. Such investment bank’s or
accountant’s determination or calculation, as the case may be, shall be final,
binding and conclusive upon the parties thereto.
