              1.

            	
              Assignor’s
                Representations and Warranties.
                The Assignor warrants and represents solely
                the following, all as determined in accordance with the Assignor’s books
                and records:

            


    

     

    
      	 	
              a.

            	
              Exhibit
                “C”
                attached hereto and incorporated herein sets forth the amounts of
                principal and interest which were outstanding under the Assigned
                Documents
                as of October 31, 2007.

            


    

     

    
      	 	
              b.

            	
              After
                review of its files, the Assignor believes that the Assigned Documents
                include all of the debt instruments held by the Assignor with respect
                to
                its loan arrangements with the Borrowers, and all material documents
                granting security for such debt instruments, and that after consummation
                of the assignment contemplated herein, the Assignor will not hold
                any
                material debt of, or security interests or liens upon any material
                property of, the Borrowers, provided,
                however,
                that it is acknowledged and understood that the Assigned Documents
                specifically do not include certain documents, instruments, and/or
                agreements relating to the purchase of, or rights with respect to,
                stock
                of the Borrowers, including, without limitation, certain securities
                purchase agreements, registration rights agreements, warrants, investor
                agreements, and the like. In the event that the Assignor locates
                additional debt or security documents that should have been included
                in
                the Assigned Documents, or if the Assignee notifies the Assignor
                in
                writing of such additional documents that should have been included
                in the
                Assigned Documents, then the Assignor execute such assignments of
                such
                documents as the Assignee may reasonably request, and, to the extent
                that
                the originals of such documents are in the Assignor’s possession, deliver
                the originals of the same to the Assignee without further
                consideration.

            


    

     

    
      	 	
              c.

            	
              The
                Assignor (i) has not previously assigned, sold, or otherwise transferred
                the Assigned Documents, (ii) has the right and authority to transfer
                the
                Assigned Documents to the Assignee, and (iii) is transferring the
                Assigned Documents to the Assignee free and clear of any liens or
                encumbrances.

            


    

     

    
      	 	
              d.

            	
              The
                execution by the Assignor of this Assignment and the performance
                by the
                Assignor of the Assignor’s obligations hereunder respectively have been
                duly authorized by all required action and will not violate any order
                of
                any court or governmental agency or any agreement by which the Assignor
                is
                bound. 

            


    

     

    
      	 	
              e.

            	
              The
                Assignor has no actual knowledge of the filing of any action against
                the
                Borrowers or the Assignor seeking to invalidate, void, set aside,
                subordinate, or otherwise impair all or some portion of the Assigned
                Documents, or the debts, claims, liens, or security interests evidenced
                by
                the Assigned Documents, nor has the Assignor received any written
                correspondence threatening such an action. For the purpose of this
                provision, the “actual knowledge” of the Assignor shall mean the actual
                knowledge of the officers of the Assignor with responsibility for
                the
                management of the Assignor’s loan arrangements with the
                Borrowers.

                is

              In
                the event that on or before eighteen (18) months from the date of
                this
                Assignment, one or more actions are commenced by a party unrelated
                to the

                their
                respective affiliates which seek(s) to invalidate, void, set aside,
                subordinate, or otherwise impair all or some portion of the debts,
                claims,
                liens or security interests securing such claims, evidenced by the
                Assigned Documents, or a bankruptcy proceeding is commenced by or
                against
                either or both of the Borrowers during such eighteen (18) month period
                and
                such an action is later commenced in that bankruptcy proceeding,
                and such
                debts, claims, liens, or security interests, or some portion thereof,
                are
                thereafter actually invalidated, voided, set aside, subordinated,
                or
                otherwise impaired, or the Assignee, in good faith and in the exercise
                of
                its reasonable discretion, settles such action(s), then the Assignee
                shall
                have the right to require the Assignor to return shares of Preferred
                Stock
                (as defined on Exhibit
                “A”)
                to Titan Electronics in a number equal to the lesser of (i) the number
                of
                shares with a value equal to (without duplication) the amount of
                the debt
                invalidated or subordinated, or value of the collateral secured by
                a lien
                or security interest that was invalidated, subordinated, or set aside,
                or
                the actual cash payments made by the Assignee to settle such claims,
                plus
                the reasonable out of pocket costs and expenses (including attorneys
                fees
                and expenses) incurred by the Assignee in defending or settling such
                action or actions, and (ii) the number of shares of Preferred Stock
                granted to the Assignor pursuant to Section 2 of Exhibit
                “A”.
                Notwithstanding the foregoing, if the Assignee subsequently receives
                a
                distribution on any of the debts, claims, liens or security interests
                which were invalidated, voided, set aside, subordinated, or otherwise
                impaired (such as a distribution in a bankruptcy to the Assignee
                as an
                unsecured creditor), then the Assignor shall be entitled to the return
                of
                Preferred Stock in an amount with a value equal to such distribution,
                less
                any reasonable out of pocket costs and expenses incurred by the Assignee
                in connection with obtaining such distribution.


            


    

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    
      	 	
              c.

            	
              Notwithstanding
                the foregoing, the Assignee agrees that to the extent that the Assignee
                recovers any funds from Jaco Electronics, Inc. or Nexus Custom
                Electronics, Inc. pursuant to (a) any cause of action arising out
                of, or
                related to, that certain Asset Purchase Agreement dated as of September
                20, 2004 entered into by and among Jaco Electronics, Inc., Nexus
                Custom
                Electronics, Inc., and the Borrowers, or any of the transactions
                relating
                thereto, including, without limitation, the current civil action
                pending
                in The United States District Court for the Southern District of
                New York
                as Case No. 06-CV-6687, or (b) as a result of a claim or claims arising
                from the sale of counterfeit inventory by Jaco Electronics, Inc.
                to the
                Borrowers prior to the date of this Assignment, then the Assignee
                will
                first apply such funds, net of the reasonable out of pocket costs
                and
                expenses (including attorneys fees and expenses) incurred by the
                Assignee
                in obtaining such funds, to any claim the Assignee may have under
                Sections
                5(a) and 5(b), before exercising its right to require the return
                of the
                Preferred Stock, and to the extent the Assignee recovers such funds
                after
                the Assignor has been required to return all or any portion of the
                Preferred Stock to the Assignee under Sections 5(a) and/or 5(b),
                above,
                then the Assignor shall be entitled to the return of Preferred Stock
                in an
                amount with a value equal to such
                recovery.

            


    

     

    
      	 	
              d.

            	
              For
                the purposes of this Section and for Section 13, the value of the
                Preferred Stock shall be calculated as the greater of (x) the liquidation
                value of the Preferred Stock as of the date of the closing on this
                Assignment, or (y) the conversion value of the Preferred Stock into
                common
                stock of Titan Electronics determined as of the date the Assignee
                makes
                demand for the return of the Preferred Stock.


            


    

     

    
      	 	
              e.

            	
              In
                the event that the Assignor is required to return shares of Preferred
                Stock to the Assignee under Sections 5(a) or 5(b) above, and the
                Assignor
                no longer holds sufficient shares of Preferred Stock to satisfy such
                requirement, then the Assignor shall return all of the shares of
                Preferred
                Stock still in its possession, and then pay to the Assignee a cash
                amount
                equal to the lesser of (a) the value of the number of shares of Preferred
                Stock that would have otherwise been returned pursuant to the formula
                set
                forth in Section 5(d) above or (b) the total proceeds actually received
                for such shares of Preferred Stock (or, to the extent, converted
                to common
                stock and then sold by Assignor, the total proceeds actually received
                for
                such underlying shares of common stock as a result of such conversion)
                that would otherwise have been returned pursuant to Section 5(d)
                above if
                such shares had not been sold, net of the reasonable costs and expenses
                (including capital gains taxes, if any) incurred by the Assignor
                in
                selling such shares. In the event that the Assignor sold shares for
                different prices, then the price per share shall be calculated as
                the
                average of such prices. The Assignee acknowledges and agrees that
                the
                decision to sell such shares, and the price received for such shares,
                is
                wholly within the discretion of the Assignor, and that when selling
                shares, the Assignor shall have no duty to obtain the highest or
                best
                price for such shares.

              Under
                no circumstances whatsoever shall the Assignor ever be required to
                return
                the TGH Shares (as defined in Exhibit
                “A”),
                or to defend the Assignee in any action of the nature described in
                this
                Section 5, or otherwise in connection with the Assigned Documents
                or the

              a.

            	
              The
                Assignee has determined to purchase this Assignment and the Assigned
                Documents following the Assignee’s own independent review and inspection
                of whatever matters the Assignee deemed necessary or appropriate

                in reliance upon any information provided by the
                Assignor.

            


    

     

    
      	 	
              b.

            	
              The
                Assignee has made its own independent investigation and evaluation

                the facts and circumstances relating to this Assignment.
                

            


    

     

    
      	 	
              c.

            	
              The
                Assignee has entered into this transaction after consultation with

              d.

            	
              The
                execution by the Assignee of this Assignment and the performance
                by the

              e.

            	
              The
                Assignee is aware that (i) as a result of the convertible feature
                of
                certain of the Assigned Documents, that such Assigned Documents may
                be
                considered securities under applicable Federal and/or state securities
                laws, (ii) the Assigned Documents, and any securities into which
                any of
                the Assigned Documents may be converted, have not been registered
                with the
                Securities and Exchange Commission or the securities commission of
                any
                state and (iii) if such securities laws are applicable, the Assigned
                Documents, or any securities into which any of the Assigned Documents
                may
                be converted, may not be offered or sold except pursuant to an effective

                transaction no subject to, the registration requirements of the Securities
                Act, and in accordance with applicable state securities laws.

              The
                Assignee is an “accredited Investor”, as defined in the Securities Act,
                and the Assignee has purchased the Assigned Documents for its own
                account,
                and not with a view to resale. The Assignee is able to bear the economic
                risk of the purchase of the Assigned Documents and it is able to
                hold the
                Assigned Documents for an indefinite period of

              The
                Assignee has done a full, complete, and exhaustive evaluation and
                investigation into the status of the Borrowers and into the status
                of any
                collateral which purportedly secures the Borrowers’ obligations under the
                Assigned Documents, including, without limitation, the Borrowers’
                financial status, the environmental condition of the collateral
                purportedly granted under any of the Assigned Documents, and the
                applicability of state and Federal fraudulent transfer and conveyance
                laws, insolvency laws, and judicially developed doctrines relevant,
                or
                similar, to any of the foregoing laws, such as preference actions,
                equitable subordination and the
                like.

              The
                Assignee acknowledges and agrees that the Purchase Price is to be
                paid in
                full to the Assignor, without adjustment whatsoever for the amount
                of
                outstanding taxes (or any other form of taxes or charges or liens
                whatsoever) affecting the collateral purportedly granted to the Assignor
                under the Assigned Documents, and the Assignee further acknowledges
                that
                the Assignee has investigated and evaluated the status of any and
                all
                outstanding taxes and understands that the Assignor is not responsible
                or
                liable in any way to the Assignee for the payment or adjustment
                thereof.

                or
                representative of the Assignor has been authorized to make, and that
                the
                Assignee has not relied upon, any statements or representations other

                Assignment.
