    THIS
COMMON STOCK PURCHASE WARRANT (the “Warrant”) certifies
that, for value received, [__] (the “Holder”) is entitled,
upon the terms and subject to the limitations on exercise and the conditions
hereinafter set forth, at any time on or after [Insert date that is six months
after Issue Date], 2010 (the “Initial Exercise
Date”) and on or prior to the close of business on the two (2) year
anniversary of the Initial Exercise Date (the “Termination Date”)
but not thereafter, to subscribe for and purchase from Genta Incorporated, a
Delaware corporation (the “Company”), up to [__]
shares (the “Warrant
Shares”) of Common Stock.  The purchase price of one share of
Common Stock under this Warrant shall be equal to the Exercise Price, as defined
in Section 2(b).  This Warrant is being issued pursuant to an
effective Registration Statement (Registration No. 333-153278) and the
prospectus thereunder.

    


    Section 1. Definitions.  Capitalized
terms used and not otherwise defined herein shall have the meanings set forth in
that certain Securities Purchase Agreement (the “Purchase Agreement”),
dated as of the Issue Date, among the Company and the purchasers signatory
thereto, as the same may be amended from time to time.

    


    Section 2. Exercise.

    


    (a) Exercise of
Warrant.  Exercise of the purchase rights represented by this
Warrant may be made, in whole or in part, at any time or times on or after the
Initial Exercise Date and on or before the Termination Date by delivery to the
Company of a duly executed facsimile copy of the Notice of Exercise annexed
hereto (or such other office or agency of the Company as it may designate by
notice in writing to the registered Holder at the address of the Holder
appearing on the books of the Company); and, within 3 Trading Days of the date
said Notice of Exercise is delivered to the Company, the Company shall have
received payment of the aggregate Exercise Price of the shares thereby purchased
by wire transfer or cashier’s check drawn on a United States
bank.  Notwithstanding anything herein to the contrary, the Holder
shall not be required to physically surrender this Warrant to the Company until
the Holder has purchased all of the Warrant Shares available hereunder and the
Warrant has been exercised in full, in which case, the Holder shall surrender
this Warrant to the Company for cancellation within 3 Trading Days of the date
the final Notice of Exercise is delivered to the Company.  Partial
exercises of this Warrant resulting in purchases of a portion of the total
number of Warrant Shares available hereunder shall have the effect of lowering
the outstanding number of Warrant Shares purchasable hereunder in an amount
equal to the applicable number of Warrant Shares purchased.  The
Holder and the Company shall maintain records showing the number of Warrant
Shares purchased and the date of such purchases.  The Company shall
deliver any objection to any Notice of Exercise within 1 business day of receipt
of such notice.  In the event of any dispute or discrepancy, the
records of the Holder shall be controlling and determinative in the absence of
manifest error. The Holder and any assignee, by acceptance of this Warrant,
acknowledge and agree that, by reason of the provisions of this paragraph,
following the purchase of a portion of the Warrant Shares hereunder, the number
of Warrant Shares available for purchase hereunder at any given time may be less
than the amount stated on the face hereof.

    


    (b) Exercise
Price.  The exercise price per share of the Common Stock under
this Warrant shall be $1.00 per share, subject to adjustment hereunder (the
“Exercise
Price”).

    (c) Exercise
Limitations.

    


    (i) Holder’s
Restrictions.  The Company shall not effect any exercise of
this Warrant, and a Holder shall not have the right to exercise any portion of
this Warrant, pursuant to Section 2 or otherwise, to the extent that after
giving effect to such issuance after exercise as set forth on the applicable
Notice of Exercise, such Holder (together with such Holder’s Affiliates, and any
other person or entity acting as a group together with such Holder or any of
such Holder’s Affiliates), would beneficially own in excess of the Beneficial
Ownership Limitation (as defined below).  For purposes of the foregoing
sentence, the number of shares of Common Stock beneficially owned by such Holder
and its Affiliates shall include the number of shares of Common Stock issuable
upon exercise of this Warrant with respect to which such determination is being
made, but shall exclude the number of shares of Common Stock which would be
issuable upon (A) exercise of the remaining, nonexercised portion of this
Warrant beneficially owned by such Holder or any of its Affiliates and (B)
exercise or conversion of the unexercised or nonconverted portion of any other
securities of the Company (including, without limitation, any other Common Stock
Equivalents) subject to a limitation on conversion or exercise analogous to the
limitation contained herein beneficially owned by such Holder or any of its
affiliates.  Except as set forth in the preceding sentence, for purposes of
this Section 2(c)(i), beneficial ownership shall be calculated in accordance
with Section 13(d) of the Exchange Act and the rules and regulations promulgated
thereunder, it being acknowledged by the Holder that the Company is not
representing to such Holder that such calculation is in compliance with Section
13(d) of the Exchange Act and such Holder is solely responsible for any
schedules required to be filed in accordance therewith.  To the extent
that the limitation contained in this Section 2(d)(i) applies, the determination
of whether this Warrant is exercisable (in relation to other securities owned by
such Holder together with any Affiliates) and of which portion of this Warrant
is exercisable shall be in the sole discretion of the Holder, and the submission
of a Notice of Exercise shall be deemed to be the Holder’s determination of
whether this Warrant is exercisable (in relation to other securities owned by
such Holder together with any Affiliates) and of which portion of this Warrant
is exercisable, in each case subject the Beneficial Ownership Limitation, and
the Company shall have no obligation to verify or confirm the accuracy of such
determination.  In addition, a determination as to any group status as
contemplated above shall be determined in accordance with Section 13(d) of the
Exchange Act and the rules and regulations promulgated
thereunder.  For purposes of this Section 2(d)(i), in determining the
number of outstanding shares of Common Stock, a Holder may rely on the number of
outstanding shares of Common Stock as reflected in (x) the Company’s most recent
Annual Report on Form 10-K or Quarterly Report on Form 10-Q, or such
similar form, as the case may be, or (y) any other notice provided by the
Company or the Company’s Transfer Agent at least 30 days prior to the date of
the submission of the Notice of Exercise setting forth the number of shares of
Common Stock outstanding.  Upon the written or oral request of a Holder,
the Company shall within two Trading Days confirm orally and in writing to such
Holder the number of shares of Common Stock then outstanding.  In any case,
the number of outstanding shares of Common Stock shall be determined after
giving effect to the conversion or exercise of securities of the Company,
including this Warrant, by such Holder or its Affiliates since the date as of
which such number of outstanding shares of Common Stock was
reported.  The “Beneficial Ownership
Limitation” shall be 4.999% of the number of shares of the Common Stock
outstanding immediately after giving effect to the issuance of shares of Common
Stock issuable upon exercise of this Warrant.  The provisions of this
paragraph shall be construed and implemented in a manner otherwise than in
strict conformity with the terms of this Section 2(d)(i) to correct this
paragraph (or any portion hereof) which may be defective or inconsistent with
the intended Beneficial Ownership Limitation herein contained or to make changes
or supplements necessary or desirable to properly give effect to such
limitation. The limitations contained in this paragraph shall apply to a
successor holder of this Warrant.

    


    (d) Mechanics of
Exercise.

    


    (i) Delivery of Certificates
Upon Exercise.  Certificates for shares purchased hereunder
shall be transmitted by the transfer agent of the Company to the Holder by
crediting the account of the Holder’s prime broker with the Depository Trust
Company through its Deposit Withdrawal Agent Commission (“DWAC”) system if the
Company is a participant in such system and otherwise by physical delivery to
the address specified by the Holder in the Notice of Exercise within three (3)
Trading Days from the receipt by the Company of the Notice of Exercise,
surrender of this Warrant and payment of the aggregate Exercise Price as set
forth above (“Warrant
Share Delivery Date”).  This Warrant shall be deemed to have
been exercised on the date the Exercise Price is received by the Company, if
such date is after Notice of Exercise and this Warrant are received by the
Company.  The Warrant Shares shall be deemed to have been issued, and
the Holder or any other person so designated to be named therein shall be deemed
to have become a holder of record of such shares for all purposes, as of the
date the Warrant has been exercised by payment to the Company of the Exercise
Price and all taxes required to be paid by the Holder, if any, pursuant to
Section 2(e)(vi) prior to the issuance of such shares, have been
paid.

    


    (ii) Delivery of New Warrants
Upon Exercise.  If this Warrant shall have been exercised in
part, the Company shall, at the request of a Holder and upon surrender of this
Warrant certificate, at the time of delivery of the certificate or certificates
representing Warrant Shares, deliver to Holder a new Warrant evidencing the
rights of Holder to purchase the unpurchased Warrant Shares called for by this
Warrant, which new Warrant shall in all other respects be identical with this
Warrant.

    


    
      
        
        

      

      
        2

        
          

        

      

      
        
        

      

       

    

    (iii) Rescission
Rights.  If the Company fails to cause its transfer agent to
transmit to the Holder a certificate or certificates representing the Warrant
Shares pursuant to this Section 2(e)(iii) by the second Trading Day immediately
following the Warrant Share Delivery Date, then the Holder will have the right
to rescind such exercise.

    


    (iv) Compensation for Buy-In on
Failure to Timely Deliver Certificates Upon Exercise.  In
addition to any other rights available to the Holder, if the Company fails to
cause its transfer agent to transmit to the Holder a certificate or certificates
representing the Warrant Shares pursuant to an exercise on or before the Warrant
Share Delivery Date, and if after such date the Holder is required by its broker
to purchase (in an open market transaction or otherwise) or the Holder’s
brokerage firm otherwise purchases, shares of Common Stock to deliver in
satisfaction of a sale by the Holder of the Warrant Shares which the Holder
anticipated receiving upon such exercise (a “Buy-In”), then the
Company 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 Warrant Shares that the Company was required to deliver to the Holder
in connection with the exercise 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 Warrant and equivalent
number of Warrant Shares for which such exercise was not honored or deliver to
the Holder the number of shares of Common Stock that would have been issued had
the Company timely complied with its exercise 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
exercise 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 Company shall be required to pay the Holder $1,000. The
Holder shall provide the Company written notice indicating the amounts payable
to the Holder in respect of the Buy-In and, upon request of the Company,
evidence of the amount of such loss.  Nothing herein shall limit a
Holder’s right to pursue any other remedies available to it hereunder, at law or
in equity including, without limitation, a decree of specific performance and/or
injunctive relief with respect to the Company’s failure to timely deliver
certificates representing shares of Common Stock upon exercise of the Warrant as
required pursuant to the terms hereof.

    


    (v) No Fractional Shares or
Scrip.  No fractional shares or scrip representing fractional
shares shall be issued upon the exercise of this Warrant.  As to any
fraction of a share which Holder would otherwise be entitled to purchase upon
such exercise, the Company shall at its election, either pay a cash adjustment
in respect of such final fraction in an amount equal to such fraction multiplied
by the Exercise Price or round up to the next whole share.

    


    (vi) Charges, Taxes and
Expenses.  Issuance of certificates for Warrant Shares shall be
made without charge to the Holder for any issue or transfer tax or other
incidental expense in respect of the issuance of such certificate, all of which
taxes and expenses shall be paid by the Company, and such certificates shall be
issued in the name of the Holder or in such name or names as may be directed by
the Holder; provided, however, that in the
event certificates for Warrant Shares are to be issued in a name other than the
name of the Holder, this Warrant when surrendered for exercise shall be
accompanied by the Assignment Form attached hereto duly executed by the Holder;
and the Company may require, as a condition thereto, the payment of a sum
sufficient to reimburse it for any transfer tax incidental thereto.

    


    (e) Closing of
Books.  The Company will not close its stockholder books or
records in any manner which prevents the timely exercise of this Warrant,
pursuant to the terms hereof.

    


    Section 3. Certain
Adjustments.

    


    (a) Stock Dividends and
Splits. If the Company, at any time while this Warrant is outstanding:
(A) pays 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 (which, for avoidance of doubt, shall not
include any shares of Common Stock issued by the Company upon exercise of this
Warrant), (B) subdivides outstanding shares of Common Stock into a larger number
of shares, (C) combines (including by way of reverse stock split) outstanding
shares of Common Stock into a smaller number of shares, or (D) issues by
reclassification of shares of the Common Stock any shares of capital stock of
the Company, then in each case the Exercise 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 immediately before such event
and of which the denominator shall be the number of shares of Common Stock
outstanding immediately after such event and the number of shares issuable upon
exercise of this Warrant shall be proportionately adjusted such that the
aggregate Exercise Price of this Warrant shall remain unchanged.  Any
adjustment made pursuant to this Section 3(a) shall become effective immediately
after the record date for the determination of stockholders entitled to receive
such dividend or distribution and shall become effective immediately after the
effective date in the case of a subdivision, combination or
re-classification.

    


    (b) Pro Rata
Distributions.  If the Company, at any time while this Warrant
is outstanding, shall distribute to all holders of Common Stock (and not to
Holders of the Warrants) evidences of its indebtedness or assets (including cash
and cash dividends) or rights or warrants to subscribe for or purchase any
security other than the Common Stock, then in each such case the Exercise Price
shall be adjusted by multiplying the Exercise Price in effect immediately prior
to the record date fixed for determination of stockholders entitled to receive
such distribution by a fraction of which the denominator shall be the Daily VWAP
determined as of the record date mentioned above, and of which the numerator
shall be such Daily VWAP on such record date less the then per share fair market
value at such record date of the portion of such assets or evidence of
indebtedness so distributed applicable to one outstanding share of the Common
Stock (determined by dividing the amount distributed by the then issued and
outstanding shares of Common Stock) as determined by the Board of Directors in
good faith.  In either case the adjustments shall be described in a
statement provided to the Holder of the portion of assets or evidences of
indebtedness so distributed or such subscription rights applicable to one share
of Common Stock.  Such adjustment shall be made whenever any such
distribution is made and shall become effective immediately after the record
date mentioned above.

    


    
      
        
        

      

      
        3

        
          

        

      

      
        
        

      

       

    

    (c) Fundamental
Transaction. If, at any time while this Warrant is outstanding, (A) the
Company effects any merger or consolidation of the Company with or into another
Person, (B) the Company effects any sale of all or substantially all of its
assets in one or a series of related transactions, (C) any tender offer or
exchange offer (whether by the Company or another Person) is completed pursuant
to which holders of Common Stock are permitted to tender or exchange their
shares for other securities, cash or property, or (D) the Company effects any
reclassification of the Common Stock or any compulsory share exchange pursuant
to which the Common Stock is effectively converted into or exchanged for other
securities, cash or property (each “Fundamental
Transaction”), then, upon any subsequent exercise of this Warrant, the
Holder shall have the right to receive, for each Warrant Share that would have
been issuable upon such exercise immediately prior to the occurrence of such
Fundamental Transaction, the number of shares of Common Stock of the successor
or acquiring corporation or of the Company, if it is the surviving corporation,
and any additional consideration (the “Alternate
Consideration”) receivable as a result of such merger, consolidation or
disposition of assets by a holder of the number of shares of Common Stock for
which this Warrant is exercisable immediately prior to such event. For purposes
of any such exercise, the determination of the Exercise Price shall be
appropriately adjusted to apply to such Alternate Consideration based on the
amount of Alternate Consideration issuable in respect of one share of Common
Stock in such Fundamental Transaction, and the Company shall apportion the
Exercise Price among the Alternate Consideration in a reasonable manner
reflecting the relative value of any different components of the Alternate
Consideration.  If holders of Common Stock are given any choice as to
the securities, cash or property to be received in a Fundamental Transaction,
then the Holder shall be given the same choice as to the Alternate Consideration
it receives upon any exercise of this Warrant following such Fundamental
Transaction.  To the extent necessary to effectuate the foregoing
provisions, any successor to the Company or surviving entity in such Fundamental
Transaction shall issue to the Holder a new warrant consistent with the
foregoing provisions and evidencing the Holder’s right to exercise such warrant
into Alternate Consideration. The terms of any agreement pursuant to which a
Fundamental Transaction is effected shall include terms requiring any such
successor or surviving entity to comply with the provisions of this Section 3(c)
and insuring that this Warrant (or any such replacement security) will be
similarly adjusted upon any subsequent transaction analogous to a Fundamental
Transaction.

    


    (d) Calculations. All
calculations under this Section 3 shall be made to the nearest cent or the
nearest 1/100th of a share, as the case may be. For purposes of this Section 3,
the number of shares of Common Stock deemed to be issued and outstanding as of a
given date shall be the sum of the number of shares of Common Stock (excluding
treasury shares, if any) issued and outstanding at the close of the Trading Day
on or, if not applicable, most recently preceding, such given date.

    


    (e) Reserved.

              (i)

            	
              Adjustment to Exercise
      Price. Whenever the Exercise Price is adjusted pursuant to any
      provision of this Section 3, the Company shall promptly mail to the Holder
      a notice setting forth the Exercise Price after such adjustment and
      setting forth a brief statement of the facts requiring such
      adjustment.

            


    

    


    
      	 
      	
              (ii)

            	
              Notice to Allow
      Exercise by Holder. If (A) the Company shall declare a dividend (or
      any other distribution in whatever form) on the Common Stock; (B) the
      Company shall declare a special nonrecurring cash dividend on or a
      redemption of the Common Stock; (C) the Company shall authorize the
      granting to all holders of the Common Stock rights or warrants to
      subscribe for or purchase any shares of capital stock of any class or of
      any rights; (D) the approval of any stockholders of the Company shall be
      required in connection with any reclassification of the Common Stock, any
      consolidation or merger to which the Company is a party, any sale or
      transfer of all or substantially all of the assets of the Company, of any
      compulsory share exchange whereby the Common Stock is converted into other
      securities, cash or property; (E) the Company shall authorize the
      voluntary or involuntary dissolution, liquidation or winding up of the
      affairs of the Company; then, in each case, the Company shall cause to be
      mailed to the Holder at its last address as it shall appear upon the
      Warrant Register of the Company, at least 20 calendar days prior to the
      applicable record or effective date hereinafter specified, a notice
      stating (x) the date on which a record is to be taken for the purpose of
      such dividend, distribution, redemption, rights or warrants, or if a
      record is not to be taken, the date as of which the holders of the Common
      Stock of record to be entitled to such dividend, distributions,
      redemption, rights or warrants are to be determined or (y) the date on
      which such reclassification, consolidation, merger, sale, transfer or
      share exchange is expected to become effective or close, and the date as
      of which it is expected that holders of the Common Stock of record shall
      be entitled to exchange their shares of the Common Stock for securities,
      cash or other property deliverable upon such reclassification,
      consolidation, merger, sale, transfer or share exchange; provided that the
      failure to 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.  Subject to applicable law, the
      Holder is entitled to exercise this Warrant during the period commencing
      on the date of such notice to the effective date of the event triggering
      such notice.  Notwithstanding the foregoing, the delivery of the
      notice described in this Section 3(f) is not intended to and shall not
      bestow upon the Holder any voting rights whatsoever with respect to
      outstanding unexercised Warrants.

    Section 4. Transfer of
Warrant.

    


    (a) Transferability.  Subject
to compliance with any applicable securities laws and the conditions set forth
in Section 4(d) hereof, this Warrant and all rights hereunder are transferable,
in whole or in part, upon surrender of this Warrant at the principal office of
the Company or its designated agent, together with a written assignment of this
Warrant substantially in the form attached hereto duly executed by the Holder or
its agent or attorney and funds sufficient to pay any transfer taxes payable
upon the making of such transfer.  Upon such surrender and, if
required, such payment, the Company shall execute and deliver a new Warrant or
Warrants in the name of the assignee or assignees and in the denomination or
denominations specified in such instrument of assignment, and shall issue to the
assignor a new Warrant evidencing the portion of this Warrant not so assigned,
and this Warrant shall promptly be cancelled.  A Warrant, if properly
assigned, may be exercised by a new holder for the purchase of Warrant Shares
without having a new Warrant issued.

    


    (b) New Warrants. This
Warrant may be divided or combined with other Warrants upon presentation hereof
at the aforesaid office of the Company, together with a written notice
specifying the names and denominations in which new Warrants are to be issued,
signed by the Holder or its agent or attorney.  Subject to compliance
with Section 4(a), as to any transfer which may be involved in such division or
combination, the Company shall execute and deliver a new Warrant or Warrants in
exchange for the Warrant or Warrants to be divided or combined in accordance
with such notice. All Warrants issued on transfers or exchanges shall be dated
the original Issue Date and shall be identical with this Warrant except as to
the number of Warrant Shares issuable pursuant thereto.

    


    (c) Warrant Register. The
Company shall register this Warrant, upon records to be maintained by the
Company for that purpose (the “Warrant Register”),
in the name of the record Holder hereof from time to time.  The
Company may deem and treat the registered Holder of this Warrant as the absolute
owner hereof for the purpose of any exercise hereof or any distribution to the
Holder, and for all other purposes, absent actual notice to the
contrary.

    


    (d) Transfer
Restrictions. If, at the time of the surrender of this Warrant in
connection with any transfer of this Warrant, the transfer of this Warrant shall
not be registered pursuant to an effective registration statement under the
Securities Act and under applicable state securities or blue sky laws, the
Company may require, as a condition of allowing such transfer, that the Holder
or transferee of this Warrant, as the case may be, furnish to the Company a
written opinion of counsel satisfactory to the Company (which opinion shall be
in form, substance and scope customary for opinions of counsel in comparable
transactions) to the effect that such transfer may be made without registration
under the Securities Act and under applicable state securities or blue sky laws,
(ii) that the transferor or transferee execute and deliver to the Company an
investment letter in form and substance acceptable to the Company and (iii) that
the transferee be an “accredited investor” as defined in Rule 501(a)(1), (a)(2),
(a)(3), (a)(7), or (a)(8) promulgated under the Securities Act or a qualified
institutional buyer as defined in Rule 144A(a)(1) promulgated under the
Securities Act.

    


    Section 5. Limited
Transferability.

    


    (a) The
Holder agrees and acknowledges that this Warrant may not be sold, transferred,
assigned or hypothecated by the Holder except in compliance with the provisions
of the Securities Act and any applicable State securities or “blue sky”
laws.

    


    Section 6. Miscellaneous.

    


    (a) No Rights as Stockholder
Until Exercise.  This Warrant does not entitle the Holder to
any voting rights or other rights as a stockholder of the Company prior to the
exercise hereof.  Upon the surrender of this Warrant and the payment
of the aggregate Exercise Price, the Warrant Shares so purchased shall be and be
deemed to be issued to such Holder as the record owner of such shares as of the
close of business on the later of the date of such surrender and
payment.

    (b) Loss, Theft, Destruction or
Mutilation of Warrant. The Company covenants that upon receipt by the
Company of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Warrant or any stock certificate relating to
the Warrant Shares, and in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to it (which, in the case of the Warrant, shall
not include the posting of any bond), and upon surrender and cancellation of
such Warrant or stock certificate, if mutilated, the Company will make and
deliver a new Warrant or stock certificate of like tenor and dated as of such
cancellation, in lieu of such Warrant or stock certificate.

    


    (c) Saturdays, Sundays,
Holidays, etc.  If the last or appointed day for the taking of
any action or the expiration of any right required or granted herein shall not
be a business day, then such action may be taken or such right may be exercised
on the next succeeding business day.

    


    (d) Authorized
Shares.

    


    The
Company covenants that during the period the Warrant is outstanding and
exercisable, it will reserve from its authorized and unissued Common Stock a
sufficient number of shares to provide for the issuance of the Warrant Shares
upon the exercise of any purchase rights under this Warrant.  The
Company further covenants that its issuance of this Warrant shall constitute
full authority to its officers who are charged with the duty of executing stock
certificates to execute and issue the necessary certificates for the Warrant
Shares upon the exercise of the purchase rights under this
Warrant.  The Company will take all such reasonable action as may be
necessary to assure that such Warrant Shares may be issued as provided herein
without violation of any applicable law or regulation, or of any requirements of
the Trading Market (as defined in the Notes) upon which the Common Stock may be
listed.  The Company covenants that all Warrant Shares which may be
issued upon the exercise of the purchase rights represented by this Warrant
will, upon exercise of the purchase rights represented by this Warrant, be duly
authorized, validly issued, fully paid and nonassessable and free from all
taxes, liens and charges created by the Company in respect of the issue thereof
(other than taxes in respect of any transfer occurring contemporaneously with
such issue).

    


    The
Company shall not by any action, including, without limitation, amending its
certificate 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 of this Warrant, but will at all times in good faith assist in the
carrying out of all such terms and in the taking of all such actions as may be
necessary or appropriate to protect the rights of Holder as set forth in this
Warrant against impairment.  Without limiting the generality of the
foregoing, the Company will (a) not increase the par value of any Warrant Shares
above the amount payable therefor upon such exercise immediately prior to such
increase in par value, (b) take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid
and nonassessable Warrant Shares upon the exercise of this Warrant, and (c) use
commercially reasonable efforts to obtain all such authorizations, exemptions or
consents from any public regulatory body having jurisdiction thereof as may be
necessary to enable the Company to perform its obligations under this
Warrant.

    


    Before
taking any action which would result in an adjustment in the number of Warrant
Shares for which this Warrant is exercisable or in the Exercise Price, the
Company shall obtain all such authorizations or exemptions thereof, or consents
thereto, as may be necessary from any public regulatory body or bodies having
jurisdiction thereof.

    


    (e) Jurisdiction. All
questions concerning the construction, validity, enforcement and interpretation
of this Warrant shall be determined in accordance with the provisions of the
Purchase Agreement.

    


    (f) Nonwaiver and
Expenses.  No course of dealing or any delay or failure to
exercise any right hereunder on the part of Holder shall operate as a waiver of
such right or otherwise prejudice Holder’s rights, powers or remedies,
notwithstanding the fact that all rights hereunder terminate on the Termination
Date.  If the Company willfully and knowingly fails to comply with any
provision of this Warrant, which results in any material damages to the Holder,
the Company shall pay to Holder such amounts as shall be sufficient to cover any
costs and expenses including, but not limited to, reasonable attorneys’ fees,
including those of appellate proceedings, incurred by Holder in collecting any
amounts due pursuant hereto or in otherwise enforcing any of its rights, powers
or remedies hereunder.

    


    (g) Notices.  Any
notice, request or other document required or permitted to be given or delivered
to the Holder by the Company shall be delivered in accordance with the notice
provisions of the Purchase Agreement.

    


    (h) Limitation of
Liability.  No provision hereof, in the absence of any
affirmative action by Holder to exercise this Warrant to purchase Warrant
Shares, and no enumeration herein of the rights or privileges of Holder, shall
give rise to any liability of Holder for the purchase price of any Common Stock
or as a stockholder of the Company, whether such liability is asserted by the
Company or by creditors of the Company.

    (i) Remedies.  Holder,
in addition to being entitled to exercise all rights granted by law, including
recovery of damages, will be entitled to specific performance of its rights
under this Warrant.  The Company agrees that monetary damages would
not be adequate compensation for any loss incurred by reason of a breach by it
of the provisions of this Warrant and hereby agrees to waive and not to assert
the defense in any action for specific performance that a remedy at law would be
adequate.

    


    (j) Successors and
Assigns.  Subject to applicable securities laws, this Warrant
and the rights and obligations evidenced hereby shall inure to the benefit of
and be binding upon the successors of the Company and the successors and
permitted assigns of Holder.  The provisions of this Warrant are
intended to be for the benefit of all Holders from time to time of this Warrant
and shall be enforceable by any such Holder or holder of Warrant
Shares.

    


    (k) Amendment.  This
Warrant may be modified or amended or the provisions hereof waived with the
written consent of the Company and the Holder.

    


    (l) Severability.  Wherever
possible, each provision of this Warrant shall be interpreted in such manner as
to be effective and valid under applicable law, but if any provision of this
Warrant shall be prohibited by or invalid under applicable law, such provision
shall be ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provisions or the remaining provisions of
this Warrant.

    


    (m) Headings.  The
headings used in this Warrant are for the convenience of reference only and
shall not, for any purpose, be deemed a part of this Warrant.
