      Company issued to the Holder on May 17, 2006 a certain warrant No.: CCP-002
      to
      purchase 15,625,000 shares of the Company’s Common Stock at an exercise price of

      and

    

    WHEREAS,
      the
      parties wish to amend the Warrant as set forth below. 

    

    NOW,
      THEREFORE,
      it is
      agreed: 

    

    
      	I.	
              Amendments.

            

    

    

    A. Section
      1(b)(xv) “Warrant
      Exercise Price”:
      Section 1(b)(xv) of the Warrant is hereby deleted in its entirety and the
      following language shall replace said Section 1(b)(xv):

    

    Section
      1(b)(xv) “Warrant
      Exercise Price”
shall
      be Five and one half Cents ($0.055) or as subsequently adjusted as provided
      in
      Section 8 hereof. 

    

    B. Section
      2(g) “Forced Exercise”: Section 2(g) of the Warrant is hereby deleted in its
      entirety and the following language shall replace said Section
      2(g):

    

    Forced
      Exercise.Provided
      the shares of Common Stock issuable here under are registered pursuant to an
      effective registration statement, the Company at its option shall have the
      right
      at any time and from time to time, if the Company’s Closing Bid Price as quoted
      by Bloomberg, LP is equal to or greater than Eleven Cents ($0.11) (the
“Forced
      Exercise Price”)
      for
      twenty (20) consecutive Trading Days (the “Forced
      Exercise Pricing Period”),
      to
      force the Holder to exercise this Warrant in whole or in part during the next
      five (5) Trading Days. In such event the Company shall provide to the Holder
      written notice at the end of business, but not later than 5:30 pm EST, on the
      last Trading Day of the Forced Exercise Pricing Period (the “Forced
      Exercise Notice”).
      The
      Holder shall have the five (5) consecutive calendar days from the day following
      receipt of the Forced Exercise Notice, to exercise this Warrant in whole or
      in
      part at or above the Forced Exercise Price as the case maybe (“Forced
      Exercise Period”).
      Furthermore during the Forced Exercise Period the Company shall only be entitled
      to force the Holder to exercise an amount equal to one fifth (1/5th)
      the
      average daily volume of the shares of the Company’s Common Stock traded, as
      quoted by Bloomberg, LP, during the Forced Exercise Pricing Period. Furthermore
      the Holder shall have the right to reduce the number of shares of Common Stock
      the Company has forced the Holder to exercise hereunder during the Forced
      Exercise Period by such number of shares of the Company’s Common Stock exercised
      by the Holder during the Forced Exercise Pricing Period. Provided however in
      the
      event that the Closing Bid Price of the Company’s Common Stock, as quoted by
      Bloomberg, LP, during the Forced Exercise Period is lower than the Forced
      Exercise Price the Company shall not have the right to force the Holder to
      exercise this Warrant, in whole or in part.

    AMENDMENT
      TO LEASE 

     

    Amendment
      to Lease (“Agreement”) made this _[20th]_
      day of
      July, 2006, by and between 1375 KINGS HIGHWAY/777 COMMERCE DRIVE ASSOCIATES,
      LLC
      and 14 MAMARONECK AVENUE REINVESTMENT ASSOCIATES, LLC (“Landlord”), each a
      Connecticut limited liability company with offices at c/o Celestial Capital
      Group, Inc., 10 East 40th
      Street,
      New York, NY 10016 and COMPETITIVE TECHNOLOGIES, INC. (“Tenant”), with offices
      1960 Bronson Road, Fairfield, Connecticut 06824.

     

    RECITALS

     

    WHEREAS,
      Landlord and Tenant entered into a lease (“Lease”) dated April 28, 2006 demising
      11,025 rentable square feet in the building known as 777 Commerce Drive,
      Fairfield, Connecticut (“Demised Premises”); and

     

    WHEREAS,
      the Term of the Lease has not yet commenced; and

     

    WHEREAS,
      the parties have agreed to reduce the number of rentable square feet of the
      Demised
      Premises set forth in the Lease Summary from 11,025 RSF to10,939 RSF, and to
      amend the Lease accordingly. 

     

    NOW,
      THEREFORE, in consideration of the mutual promises contained herein and other
      good and valuable consideration, the parties agree as follows:

     

    1.
      Lease Summary and Schedule “A” . A new Lease Summary and Schedule “A”
(Rent Schedule) in the form attached hereto shall replace the existing
      Lease
      Summary and Schedule “A” to the Lease. The “Rentable Square Feet”, “Base Rent”,
“Security Deposit”, “Tenant’s Share,” and “Tenant’s Tax Share” have been changed
      in the new Lease Summary to reflect the reduction of the rentable square footage
      of the Demised Premises from 11,025 RSF to 10,939 RSF. In addition, the
      estimated Commencement Date has been changed from July 1, 2006 to August 15,
      2006. All other terms in the Lease Summary remain the same. Schedule “A” has
      been changed in its entirety to reflect the new Annual Base Rent and Monthly
      Installment of Base Rent by reason of the reduction in the rentable square
      footage of the Demised Premises.

    
       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

      2.
        Exhibit
        “A” (Plan of Demised Premises).
        A new
        Exhibit “A” (Plan of Demised Premises) in the form attached hereto shall replace
        the existing Exhibit “A” (Plan of Demised Premises) to the Lease.

    

     

    3.
      Credit
      for Security Deposit and First Months’ Rent
      . Upon
      execution of the Lease, Tenant
      paid Landlord $41,343.84, representing the Security Deposit due under the Lease,
      and $20,671.92,
      representing the first months’ installment of Base Rent due under the Lease.
      Landlord shall give Tenant a credit against the second months’ installment of
      Base Rent due under the Lease in the amount of $483.00, representing the
      difference between the Security Deposit ($322.50) and first months’ Base Rent
      ($161.25) previously paid by Tenant upon Lease execution and the amount due
      under the Lease as amended by this Agreement.

     

    4.
      Miscellaneous.
      Except
      as amended by this Agreement, the parties confirm and ratify all the terms,
      covenants and conditions of the Lease. Unless expressly set forth to the
      contrary or modified by this Agreement, all defined terms shall have the
      meanings ascribed to them under the Lease. If there is a conflict between the
      provisions of the Lease and this Agreement, the

    provisions
      of this Agreement shall control. This Agreement shall be binding upon and shall
      inure to the benefit of the parties hereto and their respective successors
      and/or permitted assigns.

      WITNESS WHEREOF,
