              The
                parties agree that any Material provided to Lixte which is obtained
                from a

                and
                the method by which the Material was obtained, according to the procedures
                set forth in Appendix A, with the proviso that no information will
                be
                provided to Lixte which would reveal the identity of any patient
                from whom
                Material has been obtained.

                parties agree that Dr. Arndt Hartmann, Institute of Pathology, University
                of Regensburg, will act as Supervisor. Should Dr. Hartmann become
                unable
                or unwilling to perform such role, University will promptly select
                another
                individual to act as Supervisor, subject to Lixte’s approval. If a
                suitable Supervisor is not identified by the University, the parties
                acknowledge that Lixte may terminate this Agreement pursuant to Paragraph

                portions of all Materials for up to two (2) years after termination
                or
                expiration of this Agreement.

                has the right to review the quality of Material selection,
                characterization and storage at any time during the term of this
                Agreement. If the quality is less than that required for Lixte’s purposes,
                Lixte will notify Supervisor who will work with Lixte to achieve
                the
                desired level of quality.

                in the
                procedures set forth in Appendix A without incurring additional cost
                provided the changes are no more demanding with respect to University’s
                time and supplies than the requirements specified in Appendix A as
                of the
                Effective Date, and provided that the changes are in compliance with
                applicable German laws and regulations. In each instance where Lixte
                requests a change pursuant to this Paragraph, Lixte will inform University
                in writing of such request, specifying the change requested. University,
                once so informed, will thereafter implement the requested change.
                University’s obligation to implement changes requested under this
                Paragraph shall not apply retroactively to procedures followed prior
                to

                or

                effective at the end of such 60-day period unless the Breaching Party
                has
                cured any such breach or default prior to the expiration of such
                60-day

                Agreement by giving sixty (60) days’ prior written notice to Lixte in the

                Agreement, whichever amount is lower. University’s liability shall not
                cover damage caused by use of Material or services which could have

                prevented by Lixte’s examination of such Material or services at regular

              It
                is understood and agreed that University and Lixte shall each have
                the
                status of an independent contractor under this Agreement and that
                nothing
                in this Agreement shall be construed as authorization for either
                party to
                act as an agent for the other.

              University
                represents and warrants to Lixte that it is not a party to any agreement
                that would prevent it from fulfilling its obligations under this
                Agreement.

                waiver by either party hereto, whether express or implied, of any
                provision of this Agreement, or of any breach or default of either
                party
                hereto, shall not be construed to be a continuing waiver of such
                provision, a waiver of any succeeding breach or default, or a waiver
                of
                any other provision of this
                Agreement.

            


    

     

    
      	
              14.4

            	
              Should
                any part or provision of this Agreement be held unenforceable or
                in
                conflict with the law of any jurisdiction by a court or other tribunal
                of
                competent jurisdiction, all other provisions, rights and obligations
                shall
                remain in force.
