          Describe any contracts, arrangements, understandings or relationships
          (legal or otherwise) among the persons named in Item 2 and between

          relationships have been entered into. Include such information for any
          of the securities that are pledged or otherwise subject to a
          contingency the occurrence of which would give another person voting

          agreements need not be included.

          The sole stockholders of Dyna Technology, Inc. are Ralph I. Call and

          The individual Reporting Persons identified in the cover page of this
          Schedule 13D, with the exception of Nola D. Call, organized a
          Shareholders' Protective Committee (the "Committee") on March 15, 2001
          to engage in a proxy solicitation of shareholders of the Issuer to
          elect its members to the Board of Directors of the Issuer. The
          Committee was organized pursuant to the terms of the Shareholders'
          Protective Committee Letter Agreement dated March 15, 2001 (the
          "Agreement"). Under the terms of the Agreement, Ralph I. Call and Dyna
          Technology, Inc. have agreed to pay out-of pocket costs incurred by
          the members of the Committee in connection with their services on and
          to the Committee, and have further agreed to indemnify each member of
          the Committee from and against any and all costs and liabilities
          (excluding actions resulting from the bad faith, willful misconduct or
          gross negligence of such member) the members may become subject to
          based upon or arising out of the members' actions related to the proxy
          solicitation of shareholders of the Issuer.

          The Shareholder's Protective Committee was dissolved and terminated
          effective August 26, 2002 in accordance with the terms and conditions
          of a Termination Agreement effective August 26, 2002

                                    Shareholders' Protective Committee,
