      in
      which such Lien is granted (or the documentation providing for such purchase
      money indebtedness or capital lease) validly prohibits the creation of any
      other
      Encumbrance on such equipment; 

     

    (c) the
      voting equity interests in any foreign subsidiary in excess of 65% of the voting

      of
      business of any hereafter acquired equipment and has obtained a written
      commitment from an unrelated third party financing source to finance such
      equipment to the extent such financing is not prohibited under the Securities
      Purchase Agreement and, so long as no Event of Default has occurred and is
      continuing, Agent shall release or, if permitted to do so by such third party
      source, subordinate its security interest on such hereafter acquired equipment
      so financed by such third party financing source if required by such third
      party
      financing source.

      than the State of New York, the term “UCC” shall mean the Uniform Commercial
      Code as in effect in such other jurisdiction for purposes of the provisions
      of
      this Master Security Agreement relating to such attachment, perfection, priority
      or remedies and for purposes of definitions related to such provisions; provided
      further, that to the extent that the UCC is used to define any term herein
      and
      such term is defined differently in different Articles or Divisions of the
      UCC,
      the definition of such term contained in Article or Division 9 shall
      govern.

      that any such replacement or substitute Encumbrance does not secure an aggregate

      on
      the Closing Date;

      Upon the occurrence and continuance of any Event of Default, Agent, at the
      direction of Required Purchasers, will have the right to take possession of
      the
      Collateral and to maintain such possession on any Assignor’s premises or to
      remove the Collateral or any part thereof to such other premises as Agent may
      desire. Upon Agent’s request, each Assignor shall assemble or cause the
      Collateral to be assembled and make it available to Agent at a place designated
      by Agent. If any notification of intended disposition of any Collateral is
      required by law, such notification, if mailed, shall be deemed properly and
      reasonably given if mailed at least ten (10) days before such disposition,
      postage prepaid, addressed to the applicable Assignor either at such Assignor’s
      address shown herein or at any address appearing on Agent’s records for such
      Assignor. Any proceeds of any disposition of any of the Collateral shall be
      applied by Agent to the payment of all expenses in connection with the sale
      of
      the Collateral, including reasonable attorneys’ fees and other legal expenses
      and disbursements and the reasonable expenses of retaking, holding, preparing
      for sale, selling, and the like, and any balance of such proceeds shall be
      applied by Agent toward the payment of the Obligations in order provided for
      in
      the Securities Purchase Agreement. To the extent that applicable law imposes
      upon Agent duties to exercise remedies in a commercially reasonable manner,
      Assignor acknowledges that it is not commercially unreasonable if Agent: (a)
      sells the Collateral without giving any warranties as to the Collateral or
      Agent
      specifically disclaims any warranties of title or the like, (b) fails to obtain
      any required third party or government consent for access to the Collateral
      to
      be sold or for the collection or disposition of the Collateral, (c) hires or
      does not hire collectors, brokers, investment bankers, auctioneers, liquidators,
      professionals or others to assist, or manage, the collection or disposition
      of
      the Collateral, (d) conducts sales using the internet or (e) disposes of the
      Collateral in wholesale rather than retail markets. This procedure will not
      be
      considered adversely to affect the commercial reasonableness of any sale of
      the
      Collateral. If Agent sells any of the Collateral upon credit, Assignors will
      be
      credited only with payments actually made by the buyer, received by Agent and
      applied to the Obligations. In the event the buyer fails to pay for the
      Collateral, Agent may resell the Collateral. If Agent purchases any of the
      Collateral being sold, Agent may pay for the Collateral by crediting some or
      all
      of the Obligations.

    6. If
      any
      Assignor defaults in the performance or fulfillment of any of the terms,
      conditions, promises, covenants, provisions or warranties on such Assignor’s
      part to be performed or fulfilled under or pursuant to this Master Security
      Agreement and such default is continuing, Agent may, at its option without
      waiving its right to enforce this Master Security Agreement according to its
      terms, immediately or at any time thereafter and without notice to any Assignor,
      perform or fulfill the same or cause the performance or fulfillment of the
      same
      for each Assignor’s joint and several account and at each Assignor’s joint and
      several cost and expense, and the cost and expense thereof (including reasonable
      attorneys’ fees) shall be added to the Obligations and shall be payable on
      demand.

     

    7. Each
      Assignor appoints Agent, any of Agent’s officers, employees or any other person
      or entity whom Agent may designate as such Assignor’s attorney, with power to
      execute such documents in each such Assignor’s behalf and to supply any omitted
      information and correct patent errors in any documents executed by any Assignor
      or on any Assignor’s behalf; to file financing statements against such Assignor
      covering the Collateral (and, in connection with the filing of any such
      financing statements, describe the Collateral as “all assets and all personal
      property, whether now owned and/or hereafter acquired” (or any substantially
      similar variation thereof)); following the occurrence and during the continuance
      of an Event of Default, to sign such Assignor’s name on public records; and to
      endorse an Assignor’s name on checks, to send notices and to settle collections
      in Assignor’s name and to do all other things Agent deems reasonably necessary
      to carry out this Master Security Agreement. Each Assignor hereby ratifies
      and
      approves all acts of the attorney and neither Agent nor the attorney will be
      liable for any acts of commission or omission, nor for any error of judgment
      or
      mistake of fact or law other than gross negligence or willful misconduct (as
      determined by a court of competent jurisdiction in a final and non-appealable
      decision). This power being coupled with an interest, is irrevocable so long
      as
      any Obligations (other than contingent indemnity Obligations that have not
      been
      asserted by Agent or any Purchaser) remains unpaid. 

     

    8. No
      delay
      or failure on Agent’s part in exercising any right, privilege or option
      hereunder shall operate as a waiver of such or of any other right, privilege,
      remedy or option, and no waiver whatsoever shall be valid unless in writing,
      signed by Agent and then only to the extent therein set forth, and no waiver
      by
      Agent of any default shall operate as a waiver of any other default or of the
      same default on a future occasion. Agent shall have the right to enforce any
      one
      or more of the remedies available to Agent, successively, alternately or
      concurrently including the right to collect against any Assignor without first
      executing on any Collateral. Agent has no obligation to marshal any assets
      in
      favor of any Assignor, or against or in payment of any Obligations. Each
      Assignor agrees to join with Agent in executing such documents or other
      instruments in form reasonably satisfactory to Agent and in executing such
      other
      documents or instruments as may be reasonably required or deemed necessary
      by
      Agent for purposes of affecting or continuing Agent’s security interest in the
      Collateral.

    9. This
      Master Security Agreement shall be governed by and construed and enforced in
      accordance with the laws of the State of New York applicable to contracts made
      and performed in such state and cannot be terminated orally. This Master
      Security Agreement and all rights and obligations hereunder shall be binding
      upon the Assignors and their respective successors and assigns, and shall inure
      to the benefit of the Agent, the Purchasers and each of their respective
      successors and assigns.

     

    10. Each
      Assignor hereby consents and agrees that the state or federal courts located
      in
      the County of New York, State of New York shall have exclusive jurisdiction
      to
      hear and determine any claims or disputes between Assignor, on the one hand,
      and
      Agent, on the other hand, pertaining to this Master Security Agreement or to
      any
      matter arising out of or related to this Master Security Agreement, provided,
      that Agent and each Assignor acknowledges that any appeals from those courts
      may
      have to be heard by a court located outside of the County of New York, State
      of
      New York, and further provided, that nothing in this Master Security Agreement
      shall be deemed or operate to preclude Agent, to the extent necessary, from
      bringing suit or taking other legal action in any other jurisdiction to collect
      the Obligations, to realize on the Collateral or any other security for the
      Obligations, or to enforce a judgment or other court order in favor of Agent.
      Each Assignor expressly submits and consents in advance to such jurisdiction
      in
      any action or suit commenced in any such court, and each Assignor hereby waives
      any objection which it may have based upon lack of personal jurisdiction,
      improper venue or forum non conveniens.
      

     

    THE
      PARTIES DESIRE THAT THEIR DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH
      APPLICABLE LAWS. THEREFORE, TO ACHIEVE THE BEST COMBINATION OF THE BENEFITS
      OF
      THE JUDICIAL SYSTEM AND OF ARBITRATION, THE PARTIES HERETO WAIVE ALL RIGHTS
      TO
      TRIAL BY JURY IN ANY ACTION, SUIT, OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE,
      WHETHER ARISING IN CONTRACT, TORT, OR OTHERWISE BETWEEN AGENT AND/OR ANY
      PURCHASER AND/OR ANY ASSIGNOR ARISING OUT OF, CONNECTED WITH, RELATED OR
      INCIDENTAL TO THE RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH
      THIS
      MASTER SECURITY AGREEMENT OR THE TRANSACTIONS RELATED HERETO.

     

    11. It
      is
      understood and agreed that any person or entity that desires to become an
      Assignor hereunder, or is required to execute a counterpart of this Master
      Security Agreement after the date hereof pursuant to the requirements of any
      Document, shall become an Assignor hereunder by (x) executing a Joinder
      Agreement in form and substance reasonably satisfactory to Agent, (y) delivering
      supplements to such exhibits and annexes to such Documents as Agent shall
      reasonably request and (z) taking all actions as specified in this Master
      Security Agreement as would have been taken by such Assignor had it been an
      original party to this Master Security Agreement, in each case with all
      documents required above to be delivered to Agent and with all documents and
      actions required above to be taken to the reasonable satisfaction of
      Agent.

    

    
      
        
          
          

        

        
          9

          
            

          

        

        
          
          

        

      

    

     

    This
      Agreement may be executed by facsimile signatures and in any number of
      counterparts, each of which shall be an original, but all of which together
      shall constitute one agreement.

     

    12. All
      notices from Agent to any Assignor shall be sufficiently given if mailed or
      delivered to such Assignor’s address set forth below or as subsequently changed
      by Assignor in a written notice delivered to Agent in accordance with Section
      10
      hereof.

     

    13. Agent
      agrees, following the indefeasible payment in full of all Obligations (other
      than contingent indemnity Obligations that have not been asserted by Agent
      or
      any Purchaser), and so long as neither the Agent nor the Purchaser have any
      duty
      to extend any additional credit under the terms of the Documents, at Assignors’
expense, to promptly take all reasonable actions and to deliver any documents
      and certificates which are reasonably requested in writing by any Assignor
      to
      reflect the termination of the obligations of any Assignor under this Master
      Security Agreement, including without limitation the delivery of letters
      authorizing the termination of any UCC-1 financing statements filed by Agent
      pursuant to this Master Security Agreement with respect to the Collateral.
      Notwithstanding the foregoing, this Master Security Agreement shall remain
      in
      full force and effect and continue to be effective should any petition be filed
      by or against any Assignor for liquidation or reorganization, should any
      Assignor become insolvent or make an assignment for the benefit of any creditor
      or creditors or should a receiver or trustee be appointed for all or any
      significant part of any Assignor’s assets, and shall continue to be effective or
      be reinstated, as the case may be, if at any time payment and performance of
      the
      Obligations, or any part thereof, is, pursuant to applicable law, rescinded
      or
      reduced in amount, or must otherwise be restored or returned by any obligee
      of
      the Obligations, whether as a “voidable preference,” “fraudulent transfer,” or
      otherwise, all as though such payment or performance had not been made. In
      the
      event that any payment, or any part thereof, is rescinded, reduced, restored
      or
      returned, the Obligations shall be reinstated and deemed reduced only by such
      amount paid and not so rescinded, reduced, restored or returned.

     

    14. Each
      Assignor agrees to execute any further documents, and to take any further
      actions, reasonably requested by Agent to evidence or perfect the security
      interest granted herein, to maintain the first priority of the security
      interests (subject only to Permitted Encumbrances), or to effectuate the rights
      granted to Agent herein or obtain the full benefits of this Master Security
      Agreement

     

    15. In
      this
      Master Security Agreement, the following rules of construction and
      interpretation shall be applicable: (i) no reference to “proceeds” herein
      authorizes any sale, transfer, or other disposition of any Collateral by
      Assignors; (ii) “includes” and “including” are not limiting; (iii) “or” is not
      exclusive; and (iv) “all” includes “any” and “any” includes “all.”

     

    16. If
      any
      term of this Master Security Agreement shall be held to be invalid, illegal
      or
      unenforceable, the validity of all other terms hereof shall in no way be
      affected thereby, and this Master Security Agreement shall be construed and
      be
      enforceable as if such invalid, illegal or unenforceable term had not been
      included herein.

    WARRANT
      

    

    To
      Purchase ____________ Shares of Common Stock

    of

    COUGAR
      BIOTECHNOLOGY, INC.

    

    This
      Warrant and the Securities issuable upon exercise of this Warrant have not
      been
      registered under the Securities Act of 1933 (the “1933 Act”) or under any state
      securities or “Blue Sky” laws (“Blue Sky Laws”). No transfer, sale, assignment,
      pledge, hypothecation or other disposition of this Warrant or the Securities
      issuable upon exercise of this Warrant or any interest therein may be made
      except (a) pursuant to an effective registration statement under the 1933
      Act and any applicable Blue Sky Laws or (b) if the Corporation has been
      furnished with an opinion of counsel for the holder, which opinion and counsel
      shall be reasonably satisfactory to the Corporation, to the effect that no
      registration is required because of the availability of an exemption from
      registration under the 1933 Act and applicable Blue Sky laws.

    

    THIS
      CERTIFIES THAT,
      for good
      and valuable consideration ___________ (the “Holder”), or the Holder’s
      registered assigns, is entitled to subscribe for and purchase from Cougar
      Biotechnology, Inc., a Delaware corporation (the “Corporation”), at any time on
      or after June 30, 2005, to and including June 30, 2010,
      _____________________________ (_______) fully paid and nonassessable shares
      of
      the Common Stock of the Corporation at the price of $3.18 per share (the
“Warrant Exercise Price”), subject to the provisions in Section 5, of this
      Warrant.

    

    The
      shares which may be acquired upon exercise of this Warrant are referred to
      herein as the “Warrant Shares.” As used herein, the term “Holder” means the
      Holder, any party who acquires all or a part of this Warrant as a registered
      transferee of the Holder, or any record holder or holders of the Warrant Shares
      issued upon exercise, whether in whole or in part, of the Warrant. The term
      “Common Stock” means the common stock, $0.001 par value per share, of the
      Corporation.

    

    This
      Warrant is subject to the following provisions, terms and
      conditions:

    

    1. Exercise;
      Transferability.

    

    (a) The
      rights represented by this Warrant may be exercised by the Holder hereof, in
      whole or in part (but not as to a fractional share of Common Stock), by written
      notice of exercise (in the form attached hereto) delivered to the Corporation
      at
      the principal office of the Corporation prior to the expiration of this Warrant
      and accompanied or preceded by the surrender of this Warrant along with a check
      in payment of the Warrant Exercise Price for such Warrant Shares.

    

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    (b) Except
      as
      provided in Section 7 hereof, this Warrant may not be sold, transferred,
      assigned, hypothecated or divided into two or more Warrants of smaller
      denominations, nor may any Warrant Shares issued pursuant to exercise of this
      Warrant be transferred. In no event may this Warrant be transferred and divided
      (without any exercise hereof) into any denomination(s) of less than 100 Warrant
      Shares.

    

    2. Exchange
      and Replacement.
      Subject
      to Sections 1 and 7 hereof, this Warrant is exchangeable upon the surrender
      hereof by the Holder to the Corporation at its office for new Warrants of like
      tenor and date representing in the aggregate the right to purchase the number
      of
      Warrant Shares purchasable hereunder, each of such new Warrants to represent
      the
      right to purchase such number of Warrant Shares (not to exceed the aggregate
      total number purchasable hereunder) as shall be designated by the Holder at
      the
      time of such surrender. Upon receipt by the Corporation of evidence reasonably
      satisfactory to it of the loss, theft, destruction or mutilation of this
      Warrant, and, in case of loss, theft or destruction, of indemnity or security
      reasonably satisfactory to it, and upon surrender and cancellation of this
      Warrant, if mutilated, the Corporation will make and deliver a new Warrant
      of
      like tenor, in lieu of this Warrant. This Warrant shall be promptly canceled
      by
      the Corporation upon the surrender hereof in connection with any exchange or
      replacement. The Corporation shall pay all expenses, taxes (other than stock
      transfer taxes), and other charges payable in connection with the preparation,
      execution, and delivery of Warrants pursuant to this
      Section 2.

    

    3. Issuance
      of the Warrant Shares.

    

    (a) The
      Corporation agrees that the Warrant Shares shall be and are deemed to be issued
      to the Holder as of the close of business on the date on which this Warrant
      shall have been surrendered and the payment made for such Warrant Shares as
      aforesaid. Subject to the provisions of paragraph (b) of this Section 3,
      certificates for the Warrant Shares so purchased shall be delivered to the
      Holder within a reasonable time after the rights represented by this Warrant
      shall have been so exercised, and, unless this Warrant has expired, a new
      Warrant representing the right to purchase the number of Warrant Shares, if
      any,
      with respect to which this Warrant shall not then have been exercised shall
      also
      be delivered to the Holder.

    

    (b) Notwithstanding
      the foregoing, however, the Corporation shall not be required to deliver any
      certificate for Warrant Shares upon exercise of this Warrant except in
      accordance with exemptions from the applicable securities registration
      requirements or registrations under applicable securities laws. Except as
      described in Section 9, nothing herein shall obligate the Corporation to effect
      registrations under federal or state securities laws. If registrations are
      not
      in effect and if exemptions are not available when the Holder seeks to exercise
      the Warrant, the Warrant exercise period will be extended, if need be, to
      prevent the Warrant from expiring, until such time as either registrations
      become effective or exemptions are available, and the Warrant shall then remain
      exercisable for a period of at least 30 calendar days from the date the
      Corporation delivers to the Holder written notice of the availability of such
      registrations or exemptions. The Holder agrees to execute such documents and
      make such representations, warranties and agreements as may be required solely
      to comply with the exemptions relied upon by the Corporation, or the
      registrations made, for the issuance of the Warrant Shares.

    4. Covenants
      of the Corporation.
      The
      Corporation covenants and agrees that all Warrant Shares will, upon issuance,
      be
      duly authorized and issued, fully paid, non-assessable and free from all taxes,
      liens and charges with respect to the issue thereof. The Corporation further
      covenants and agrees that during the period within which the rights represented
      by this Warrant may be exercised, the Corporation will at all times have
      authorized and reserved for the purpose of issue or transfer upon exercise
      of
      the subscription rights evidenced by this Warrant a sufficient number of shares
      of Common Stock to provide for the exercise of the rights represented by this
      Warrant.

    

    5. Anti-dilution
      Adjustments.
      The
      provisions of this Warrant are subject to adjustment as provided in this
      Section 5.

    

    (a) Stock
      Splits, Dividends and Combinations.
      The
      Warrant Exercise Price shall be adjusted from time to time such that in case
      the
      Corporation shall hereafter:

    

    (i)
      pay any
      dividends on any class of stock of the Corporation payable in Common Stock
      or
      securities convertible into Common Stock;

    

    (ii)
      subdivide its then outstanding shares of Common Stock into a greater number
      of
      shares; or

    

    (iii)
      combine
      outstanding shares of Common Stock, by reclassification or
      otherwise;

    

    then,
      in
      any such event, the Warrant Exercise Price in effect immediately prior to such
      event shall (until adjusted again pursuant hereto) be adjusted immediately
      after
      such event to a price (calculated to the nearest full cent) determined by
      dividing (A) the number of shares of Common Stock outstanding immediately
      prior to such event, multiplied by the then existing Warrant Exercise Price,
      by
      (B) the total number of shares of Common Stock outstanding immediately
      after such event (including in each case the maximum number of shares of Common
      Stock issuable in respect of any securities convertible into Common Stock),
      and
      the resulting quotient shall be the adjusted Warrant Exercise Price per share.
      An adjustment made pursuant to this Subsection shall become effective
      immediately after the record date in the case of a dividend or distribution
      and
      shall become effective immediately after the effective date in the case of
      a
      subdivision, combination or reclassification. If, as a result of an adjustment
      made pursuant to this Subsection, the Holder of any Warrant thereafter
      surrendered for exercise shall become entitled to receive shares of two or
      more
      classes of capital stock or shares of Common Stock and other capital stock
      of
      the Corporation, the Board of Directors (whose determination shall be
      conclusive) shall determine the allocation of the adjusted Warrant Exercise
      Price between or among shares of such classes of capital stock or shares of
      Common Stock and other capital stock. All calculations under this Subsection
      shall be made to the nearest cent or to the nearest 1/100 of a share, as the
      case may be. In the event that at any time as a result of an adjustment made
      pursuant to this Subsection, the holder of any Warrant thereafter surrendered
      for exercise shall become entitled to receive any shares of the Corporation
      other than shares of Common Stock, thereafter the Warrant Exercise Price of
      such
      other shares so receivable upon exercise of any Warrant shall be subject to
      adjustment from time to time in a manner and on terms as nearly equivalent
      as
      practicable to the provisions with respect to Common Stock contained in this
      Section.

    (b) Mechanics
      of Adjustment for Stock Splits, Dividends and Combinations.
      Upon
      each adjustment of the Warrant Exercise Price pursuant to Section 5(a)
      above, the Holder of each Warrant shall thereafter (until another such
      adjustment) be entitled to purchase at the adjusted Warrant Exercise Price
      the
      number of shares, calculated to the nearest full share, obtained by multiplying
      the number of shares specified in such Warrant (as adjusted as a result of
      all
      adjustments in the Warrant Exercise Price in effect prior to such adjustment)
      by
      the Warrant Exercise Price in effect prior to such adjustment and dividing
      the
      product so obtained by the adjusted Warrant Exercise Price.

    

    (c) Consolidations,
      Mergers and Reorganization Events.
      In case
      of any consolidation or merger to which the Corporation is a party other than
      a
      merger or consolidation in which the Corporation is the continuing corporation,
      or in case of any sale or conveyance to another corporation of the property
      of
      the Corporation as an entirety or substantially as an entirety, or in the case
      of any statutory exchange of securities with another corporation (including
      any
      exchange effected in connection with a merger of a third corporation into the
      Corporation), there shall be no adjustment under Subsection (a) of this
      Section 5; but the Holder of each Warrant then outstanding shall have the right
      thereafter to convert such Warrant into the kind and amount of shares of stock
      and other securities and property which he would have owned or have been
      entitled to receive immediately after such consolidation, merger, statutory
      exchange, sale or conveyance had such Warrant been converted immediately prior
      to the effective date of such consolidation, merger, statutory exchange, sale
      or
      conveyance and, in any such case, if necessary, appropriate adjustment shall
      be
      made in the application of the provisions set forth in this Section with respect
      to the rights and interests thereafter of any Holders of the Warrant, to the
      end
      that the provisions set forth in this Section shall thereafter correspondingly
      be made applicable, as nearly as may reasonably be, in relation to any shares
      of
      stock and other securities and property thereafter deliverable on the exercise
      of the Warrant. The provisions of this Subsection shall similarly apply to
      successive consolidations, mergers, statutory exchanges, sales or
      conveyances.

     

    (d) Certificate
      as to Adjustments.
      Upon
      the occurrence of each adjustment or readjustment of the Warrant Exercise Price
      or the number of Warrants covered hereby pursuant to this Section, the
      Corporation, 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 or readjustment and showing in detail
      the facts upon which such adjustment or readjustment is based. The Corporation
      shall, upon the written request at any time of the Holder, furnish or cause
      to
      be furnished to the Holder a like certificate setting forth (i) such
      adjustments and readjustments, (ii) the Warrant Exercise Price at the time
      in effect, and (iii) the number of shares of Common Stock and the amount,
      if any, of other property which at the time would be received upon the exercise
      of this Warrant.

    6. No
      Voting Rights.
      This
      Warrant shall not entitle the Holder to any voting rights or other rights as
      a
      stockholder of the Corporation.

    

    7. Notice
      of Transfer of Warrant or Resale of the Warrant Shares.

    

    (a) Subject
      to the sale, assignment, hypothecation or other transfer restrictions set forth
      in Section 1 hereof, the Holder, by acceptance hereof, agrees to give
      written notice to the Corporation before transferring this Warrant or
      transferring any Warrant Shares of such Holder's intention to do so, describing
      briefly the manner of any proposed transfer. Promptly upon receiving such
      written notice, the Corporation shall present copies thereof to the
      Corporation's counsel. If in the opinion of such counsel the proposed transfer
      may be effected without registration or qualification (under any federal or
      state securities laws), the Corporation, as promptly as practicable, shall
      notify the Holder of such opinion, whereupon the Holder shall be entitled to
      transfer this Warrant or to dispose of Warrant Shares received upon the previous
      exercise of this Warrant, all in accordance with the terms of the notice
      delivered by the Holder to the Corporation; provided that an appropriate legend
      may be endorsed on this Warrant or the certificates for such Warrant Shares
      respecting restrictions upon transfer thereof necessary or advisable in the
      opinion of counsel and satisfactory to the Corporation to prevent further
      transfers which would be in violation of Section 5 of the 1933 Act and
      applicable state securities laws; and provided further that the prospective
      transferee or purchaser shall execute such documents and make such
      representations, warranties and agreements as may be required solely to comply
      with the exemptions relied upon by the Corporation for the transfer or
      disposition of the Warrant or Warrant Shares.

    

    (b) If,
      in
      the opinion of the Corporation’s counsel, the proposed transfer or disposition
      of this Warrant or such Warrant Shares described in the written notice given
      pursuant to this Section 7 may not be effected without registration or
      qualification of this Warrant or such Warrant Shares, the Corporation shall
      promptly give written notice thereof to the Holder, and the Holder will limit
      its activities in respect to such transfer or disposition as, in the opinion
      of
      such counsel, are permitted by law.

    

    8. Fractional
      Shares.
      Fractional shares shall not be issued upon the exercise of this Warrant, but
      in
      any case where the holder would, except for the provisions of this Section,
      be
      entitled under the terms hereof to receive a fractional share, the Corporation
      shall, upon the exercise of this Warrant for the largest number of whole shares
      then called for, pay a sum in cash equal to the sum of (a) the excess, if
      any, of the Market Price of such fractional share over the proportional part
      of
      the Warrant Exercise Price represented by such fractional share, plus
      (b) the proportional part of the Warrant Exercise Price represented by such
      fractional share. For purposes of this Section, the term “Market Price” with
      respect to shares of Common Stock of any class or series means the last reported
      sale price or, if none, the average of the last reported closing bid and asked
      prices on any national or regional securities exchange or quoted in the National
      Association of Securities Dealers, Inc.'s Automated Quotations System
      (“Nasdaq”), or if not listed on a national or regional securities exchange or
      quoted in Nasdaq, the average of the last reported closing bid and asked prices
      as reported by the OTC Bulletin Board from quotations by market makers in such
      Common Stock, or if no quotations in such Common Stock are available, the fair
      market value of the shares as determined in good faith by the Board of Directors
      of the Corporation.

    9. Registration
      Rights. If
      at any
      time prior to the expiration of this Warrant the Corporation shall propose
      to
      file any registration statement (other than any registration on Form S-4, S-8
      or
      any other similarly inappropriate form, or any successor forms thereto) under
      the 1933 Act covering a public offering of the Common Stock (a “Registration
      Statement”), it will notify the Holder hereof at least twenty (20) days prior to
      each such filing and will use its best efforts to include in the Registration
      Statement (to the extent permitted by applicable regulation), the Warrant Shares
      to the extent requested by the Holder hereof within ten (10) days after receipt
      of notice of such filing (which request shall specify the interest in this
      Warrant or the Warrant Shares intended to be sold or disposed of by such Holder
      and describe the nature of any proposed sale or other disposition thereof);
      provided,
      however,
      that if
      a greater number of Warrant Shares is offered for participation in the proposed
      offering than in the reasonable opinion of the managing underwriter of the
      proposed offering can be accommodated without adversely affecting the proposed
      offering, then the amount of Warrant Shares proposed to be offered by such
      Holders for registration, as well as the number of securities of any other
      selling shareholders participating in the registration, shall be proportionately
      reduced to a number deemed satisfactory by the managing underwriter. The
      Corporation shall bear all expenses and fees incurred in connection with the
      preparation, filing, and amendment of the Registration Statement, except that
      the Holder shall pay all fees, disbursements and expenses of any counsel or
      expert retained by the Holder and all underwriting discounts and commissions,
      filing fees and any transfer or other taxes relating to the Warrant Shares
      included in the Registration Statement. As a condition precedent to the
      Corporation’s obligations under this Section 9, the Holder agrees to cooperate
      with the Corporation in the preparation and filing of any Registration
      Statement, and in the furnishing of information concerning the Holder for
      inclusion therein, or in any efforts by the Corporation to establish that the
      proposed sale is exempt under the 1933 Act as to any proposed
      distribution.
