3. DEVELOPMENT SCHEDULE

3.1  DRI shall develop the Technology in accordance with the development
     schedule mutually agreed upon between the parties hereto, which is set
     forth in Exhibit-B


                                       1





     attached hereto ("Development Schedule") and made a part hereof. DRI agrees
     to fully comply with the Development Schedule, and further agrees that time
     is of the essence with respect to its performance of this Agreement. In
     order for KME to keep the Development Schedule, KME shall have the right,
     at any time during the term of this Agreement, to review DRI's progress in

5. DELIVERABLES AND EVALUATION

     5.1  DRI shall, at its own expense, on or before the date specified in the
          Development Schedule, provide KME with Deliverables, as well as
          complete documentation and any other items therefor, as may be
          required by KME for its acceptance testing/evaluation of the
          Technology at facility agreed by the parties.

     5.2  Within (60) days after the receipt of the Deliverables and
          documentation and any

                                        2





          other items therefor at the time of the completion of each Milestone
          by DRI, KME shall conduct evaluation of the Technology whether or not
          the Technology conforms to the Specification. Upon the request of KME,
          DRI agrees to corporate with KME's evaluation at free of charge. In
          the event that the Technology conforms to the Specification, KME shall
          accept the Technology. In the event that KME decide to reject the
          Technology, such rejection shall be advised to DRI in writing
          specifying the reasons for such rejection, KME shall afford DRI one
          (1) reasonable opportunity to correct any identified problems and
          resubmit at least (1) additional prototype of the Technology and
          documentation and any other items therefor to KME, at the expense of
          DRI, for re-evaluation of the Technology. If, after such second
          evaluation, the parties negotiate and determine in good faith, due to
          the failure of the Technology to conform to the Specification, then:
          (a) the payments to which DRI shall be entitled pursuant to Article 6
          of this Agreement shall be reduced by such amount as the parties
          negotiate and determine in good faith, to be appropriate as a result
          of the reduction in value to KME of the Technology due to such failure
          of the Technology to conform to the Specification. The prototypes and
          the copies of the documentation and any other items therefor, as
          delivered to KME, shall become the property of KME pursuant to Article
          5 of this Agreement, except as may be otherwise expressly provided
          herein; or (b) KME shall be entitled to terminate this Agreement, and
          DRI shall, without prejudice to any other rights and remedies of KME,
          forthwith refund to KME all development fees previously paid by KME to
          DRI under this Agreement.

6. DEVELOPMENT FEE AND PAYMENT

     6.1  In consideration to the obligation of DRI to complete the development
          of the Technology hereunder, KME shall pay to DRI;

     6.2  KME shall reserve the right to terminate this Agreement if KME
          decides, at its sole discretion, that the development work made by DRI
          pursuant to the Development Schedule does not meet the requirement of
          KME after KME inspects the process of the development at the time of
          the completion of each Milestone by DRI. Upon termination of the
          Agreement pursuant to this Article 6.2 hereof, KME shall pay only the
          development fee due corresponding to the completion of the Milestone
          by DMI and KME shall be relieved from any obligation to pay further

               (b)  upon or after any adjudication that the other party is

          agrees to destroy all reproduction materials delivered to KME by DRI
          immediately after such termination or expiration, except for
          necessary materials to use only for the purposes of offering continued

15.  TERMINATION FOR CONVENIENCE

     KME may, in its sole and absolute discretion, terminate this Agreement,
     with or without cause, upon (60) days prior written notice to DRI. In the
     event of any such termination, DRI shall immediately turn over to KME all
     work completed or in process by DRI in connection with the development of
     the Technology to the date of such termination, which work and materials
     shall thereupon become the exclusive property of KME. In consideration for
     DRI turning over to KME all work completed or in process pursuant to this
     paragraph, KME may thereupon pay DRI an amount ("Compensation Amount"


                                        7


   




     which the parties negotiate and determine in good faith, is adequate

     from an amount paid by KME in accordance with Article 6.

     16.1 It is expressly understood and agreed that DRI is, and shall at all
          times during the term of this Agreement be deemed to be, an

          be deemed or construed to constitute DRI an agent or employee of KME,
          nor shall DRI have the right or authority to act for, incur, assume or
          create any obligation, responsibility or liability, express or
          implied, in the name of, or on behalf of, KME, or to bind KME, in any
          manner whatsoever. DRI's employees shall be deemed to be the agents,
          servants and employees of DRI only, and KME shall incur no obligations
          or liabilities of any kind, nature or sort, express or implied, by
          virtue of, or with respect to, the conduct or such employees.

          independent contractors as necessary in their business discretion to
          perform the terms of this Agreement.
