      hereby certifies that, for value received,
      Ian
      Kirby, located at 560 N. Kings Road #3, West Hollywood, CA 90048   (the

      is the
      owner of the number of unit purchase warrants (“Warrants”)
      which
      entitles the holder thereof to purchase, at any time during the period
      commencing on the Commencement Date (as defined herein) and ending on the
      Expiration Date (as defined herein), Five Hundred and Fifty six (556) fully
      paid
      and non-assessable units of Membership Interest (as defined in the Company's
      Operating Agreement dated as of July 5, 2005, as amended to date (the "Operating
      Agreement")) in the Company (each a "Unit"), each representing a Percentage
      Interest (as defined in the Operating Agreement) equal to 0.0009890% on a
      fully-diluted basis as of the date hereof at a purchase price equal to the
      Exercise Price (as defined below) in lawful money of the United States of
      America in cash, subject to adjustment as hereinafter provided. Each Unit shall
      include the right to receive allocations of Net Profits and Net Losses and
      distributions from the Company. For the avoidance of doubt, the securities
      which
      the Warrant Holder is permitted to purchase hereunder (whether prior to or
      after
      adjustment of the Warrant Units or securities to which this Warrant applies)
      shall be equal to .5499% of the total equity securities of the Company on a
      fully-diluted basis as of the date hereof.

     

    1. WARRANT;
      EXERCISE PRICE.

     

    1.1 This
      Warrant is issued pursuant to a Subscription Agreement dated as of the date
      hereof, by and among the Company and the Warrant Holder (the “Subscription
      Agreement”).


    
      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

    

     

    1.2 Each
      Warrant shall entitle the Warrant Holder to purchase one Unit (individually,
      a
“Warrant
      Unit”
      severally, the “Warrant
      Units”).
      Each
      Warrant Unit shall provide the holder of such Unit with a capital account
      balance equal to the exercise price paid for such Warrant Unit. 

     

    1.3 The
      purchase price payable upon exercise of each Warrant (the “Exercise
      Price”)
      shall
      be (i) in the event that the Company completes a merger of the Company with
      and
      into Lifesciences Opportunities, Inc. (the "Merger"), (A) the actual exercise
      price for a Warrant issued in the Company's next equity financing (whether
      completed before, after or contemporaneously with the Merger), subject to any
      adjustments pursuant to Section 8 to make such Warrant equivalent to the
      Warrants hereunder, (B) if no Warrant is offered in the next equity financing
      (whether completed before, after or contemporaneously with the Merger), then
      in
      such event only, the purchase price per security which the Warrant Holder is
      entitled to purchase upon the exercise of this Warrant will be equal to the
      actual purchase price paid for each such security in the next equity financing,
      or (C) if no such financing is completed by the Company after the Merger, then
      the purchase price per security which the Warrant Holder is entitled to purchase
      shall be equal to (1) the Exercise Price identified in (ii) below (as adjusted
      by the provisions of Article 8), divided by (2) the number of shares or other
      securities issuable or exchangeable for each Warrant through the Merger) or
      (ii)
      if the Warrant is exercised prior to the Merger, then the exercise price shall
      be $92.72 per Unit, subject to any adjustments pursuant to Section 8.
      Notwithstanding the foregoing, the Exercise Price and number of Warrant Units
      purchasable pursuant to each Warrant are subject to adjustment as provided
      in
      Section 8.

    (a) a
      certificate or certificates for the number of full Warrant Units to which such
      Warrant Holder shall be entitled upon such exercise , and

      currently stated on the face of this Warrant minus the number of such Units
      purchased by the Warrant Holder upon such exercise as provided in Section 2.2
      (in each case prior to any adjustments made thereto pursuant to the provisions
      of this Warrant).

     

    3. REGISTRATION
      AND TRANSFER ON COMPANY BOOKS.
      

     

    3.1 The
      Company (or an agent of the Company) will maintain a register containing the

      reasonable efforts to cause all Warrant Units issuable upon exercise of the
      Warrants to be listed (subject to official notice of issuance) on each Exchange

      any
      successor electronic quotation service and trading market) on which the
      Company's Membership Interests are then listed and/or quoted, if
      any. 

     

    5. EXCHANGE,
      TRANSFER, ASSIGNMENT OR LOSS OR MUTILATION OF WARRANTS.
      This
      Warrant is exchangeable, without expense, at the option of the Warrant Holder,
      upon presentation and surrender hereof to the Company for other warrants of
      different denominations entitling the holder thereof to purchase in the
      aggregate the same number of Units purchasable hereunder. Subject to the terms
      of Sections 6 and 7, upon surrender of this Warrant to the Company at its
      principal office or at the office of its transfer agent, if any, with the
      Assignment Form annexed hereto duly executed and funds sufficient to pay any

      and,
      in the case of loss, theft or destruction, of indemnity reasonably satisfactory
      to the Company, or, in the case of mutilation, upon surrender and cancellation
      of the mutilated Warrant, the Company shall execute and deliver in lieu thereof
      a new Warrant of like tenor and date representing an equal number of Warrants.

    6. LIMITATION
      ON EXERCISE AND SALES.
      

     

    (a)
       Each
      holder of this Warrant acknowledges that this Warrant and the Warrant Units
      have
      not been registered under the Securities Act, as of the date of issuance hereof.
      This Warrant only may be transferred in compliance with this Section 6 and
      Section 7. The Company shall be under no obligation to issue the Units covered
      by such exercise unless and until the Warrant Holder shall have executed the
      form of exercise annexed hereto that states that at the time of such exercise
      that it is then an “accredited investor” within the meaning of Rule 501 of
      Regulation D, is acquiring such Units for its own account, and will not transfer
      the Warrant Units unless pursuant to an effective and current registration
      statement under the Securities Act or an exemption from the registration
      requirements of the Securities Act and any other applicable restrictions, in
      which event the Warrant Holder shall be bound by the provisions of a legend
      or
      legends to such effect that shall be endorsed upon the certificate(s)
      representing the Warrant Units issued pursuant to such exercise. In such event,
      the Warrant Units issued upon exercise hereof shall be imprinted with a legend
      in substantially the form provided in Section 7(b). 

    


    (b) Warrant
      Holder represents and warrants that it is acquiring this Warrant for its own
      account, for purposes of investment, and not with a view to, or for sale in
      connection with, any distribution thereof within the meaning of the Securities
      Act and the rules and regulations promulgated thereunder. Warrant Holder
      represents, warrants and agrees that it will not sell, exercise, transfer or
      otherwise dispose of this Warrant (or any interest therein) or any of the Units
      purchasable upon exercise hereof, except pursuant to (i) an effective
      registration statement under the Securities Act and applicable state securities
      laws or (ii) an opinion of counsel, satisfactory to Company, that an exemption
      from registration under the Securities Act and such laws is available. Warrant
      Holder further acknowledges and agrees that Company is not required, legally
      or
      contractually, so to register or qualify the Warrant or such Units or to take
      any action to make such an exemption available. Warrant Holder understands
      that
      Company will be relying upon the truth and accuracy of the representations
      and
      warranties contained in this Section 6 in issuing this Warrant and such Units
      without first registering the issuance thereof under the Securities Act or
      qualifying or registering the issuance thereof under any state securities laws
      that may be applicable.

    


    (c) Warrant
      Holder acknowledges that (i) there is not now, and there may not be in the
      future, any public market for the Warrant, (ii) although there currently is
      not
      a public trading market for the Units, there can be no assurance that any such
      market will be created and sustained, and (iii) there can be no assurance that
      Warrant Holder will be able to liquidate its investment in Company. Warrant
      Holder represents and warrants that it is familiar with and understands the
      terms and conditions of Rule 144 promulgated under the Securities
      Act.

    


    (d)
       Warrant
      Holder represents and warrants to Company that (i) it has such knowledge and
      experience in financial and business matters as is necessary to enable it to
      evaluate the merits and risks of any investments in Company and is not utilizing
      any other person to be a purchaser representative in connection with evaluation
      of such merits and risks; and (ii) it has no need for liquidity in an investment
      in Company and is able to bear the risk of that investment for an indefinite
      period and to afford a complete loss thereof.


    
      
        
        

      

      
        4

        
          

        

      

      
        
        

      

    

     

    (e) Warrant
      Holder represents and warrants that it has had access to, and has been furnished
      with, all of the information it has requested from Company and has had an
      opportunity to review the books and records of Company and to discuss with
      management and members of the board of directors of Company the business and
      financial affairs of Company.

    


    (f)
       Warrant
      Holder agrees that at the time of each exercise of this Warrant, unless the
      issuance of Units issuable thereupon is pursuant to an effective registration
      statement under the Securities Act and under applicable state blue sky laws,
      Warrant Holder will provide Company with a letter embodying the representations
      and warranties set forth in subsections (b) through (e), in form and substance
      reasonably satisfactory to Company, and agrees that the certificate(s)
      representing any shares issued to it upon any exercise of this Warrant may
      bear
      such restrictive legend as Company may deem necessary to reflect the restricted
      status of such shares under the Securities Act unless Company shall have
      received from Warrant Holder an opinion of counsel to Warrant Holder, reasonably
      satisfactory in form and substance to Company and its counsel, that such
      restrictive legend is not required.

     

    7. TRANSFER
      RESTRICTIONS.

     

    (a) 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 (i) that the Warrant Holder or transferee
      of
      this Warrant, as the case may be, furnish to the Company a written opinion
      of
      counsel (which opinion shall be in form, substance and scope customary for
      opinions of counsel in comparable transactions and reasonably satisfactory
      to
      counsel for the Company) 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 holder or transferee execute and deliver to the Company an investment letter
      in form and substance acceptable to the Company, (iii) that transferee agree
      in
      writing with the Company to be bound by the terms and conditions of this Warrant
      applicable to the Warrant Holder and (iv) that the transferee be an “accredited
      investor” as defined in Regulation D promulgated under the Securities
      Act.

     

    (b) The
      Units
      issuable on the exercise of the Warrant shall bear the following
      legend:

     

    THESE
      SECURITIES HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION,
      OR THE SECURITIES COMMISSION OF ANY STATE, IN RELIANCE UPON AN EXEMPTION FROM
      REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
      ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN
      EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN
      AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
      REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE
      SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR
      TO
      SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE
      COMPANY.

     

    
      
        
        

      

      
        5

        
          

        

      

      
        
        

      

    

     

    (c) The
      Holder acknowledges that the Warrant Units acquired upon the exercise of this
      Warrant, if not registered, will have restrictions upon resale imposed by state
      and federal securities laws.

     

    8. ADJUSTMENT
      OF EXERCISE PRICE AND NUMBER OF UNITS DELIVERABLE.
      The
      Exercise Price and the number of Warrant Units purchasable pursuant to each
      Warrant shall be subject to adjustment from time to time as hereinafter set
      forth in this Section 8: 

     

    (a) In
      case,
      prior to the expiration of this Warrant by exercise or by its terms, the Company
      shall issue any additional units of Membership Interest as a dividend or
      subdivide the number of outstanding Units into a greater number of units of
      Membership Interest, then in either of such cases, the then applicable Exercise
      Price per Warrant Unit purchasable pursuant to this Warrant in effect at the
      time of such action shall be proportionately reduced and the number of Warrant
      Units at that time purchasable pursuant to this Warrant shall be proportionately
      increased; and conversely, in the event the Company shall reduce the number
      of
      outstanding units of Membership Interest by combining such units into a smaller
      number of units of Membership Interest then, in such case, the then applicable
      Exercise Price per Warrant Unit purchasable pursuant to this Warrant in effect
      at the time of such action shall be proportionately increased and the number
      of
      Warrant Units at that time purchasable pursuant to this Warrant shall be
      proportionately decreased. If the Company shall, at any time during the life
      of
      this Warrant, declare a dividend payable in cash on its Membership Interest
      and
      shall at substantially the same time offer to its stockholders a right to
      purchase new units of Membership Interest from the proceeds of such dividend
      or
      for an amount substantially equal to the dividend, all units of Membership
      Interest so issued shall, for the purpose of this Warrant, be deemed to have
      been issued as a dividend. Any dividend paid or distributed upon the Membership
      Interests in units of any other class of securities convertible into units
      of
      Membership Interest shall be treated as a dividend paid in units of Membership
      Interest to the extent that units of Membership Interest are issuable upon
      conversion thereof.

     

    (b) In
      case,
      prior to the expiration of this Warrant by exercise or by its terms, the Company
      shall be recapitalized by reclassifying its outstanding units of Membership
      Interest, (or the Company or a successor corporation shall consolidate or merge
      with or convey all or substantially all of its or of any successor corporation’s
      property and assets to any other corporation or corporations (any such other
      corporations being included within the meaning of the term “successor
      corporation” hereinbefore used in the event of any consolidation or merger of
      any such other corporation with, or the sale of all or substantially all of
      the
      property of any such other corporation to, another corporation or corporations),
      then, as a condition of such recapitalization, consolidation, merger or
      conveyance, lawful and adequate provision shall be made whereby the holder
      of
      this Warrant shall thereafter have the right to purchase, upon the basis and
      on
      the terms and conditions specified in this Warrant, in lieu of the Warrant
      Units
      theretofore purchasable upon the exercise of this Warrant, such shares of stock,
      securities or assets, as may be issued or payable with respect to, or in
      exchange for, the number of Warrant Units theretofore purchasable upon the
      exercise of this Warrant had such recapitalization, consolidation, merger,
      or
      conveyance not taken place, and the exercise price for which shall have been
      appropriately adjusted to reflect the number of securities which the Warrant
      Holder is entitled to purchase in exchange for such Warrant; and in any such
      event, the rights of the Warrant Holder to any adjustment in the number of
      Warrant Units purchasable upon the exercise of this Warrant, as herein provided,
      shall continue and be preserved in respect of any stock which the Warrant Holder
      becomes entitled to purchase.

    (c) In
      case
      the Company at any time while this Warrant shall remain unexpired and
      unexercised shall sell all or substantially all of its property or dissolve,
      liquidate, or wind up its affairs, lawful provision shall be made as part of
      the
      terms of any such sale, dissolution, liquidation or winding up, so that the
      holder of this Warrant may thereafter receive upon exercise hereof in lieu
      of
      each Warrant Unit that it would have been entitled to receive, the same kind
      and
      amount of any securities or assets as may be issuable, distributable or payable
      upon any such sale, dissolution, liquidation or winding up with respect to
      each
      Unit of the Company, provided, however, that in any case of any such sale or
      of
      dissolution, liquidation or winding up, the right to exercise this Warrant
      shall
