          of the Executive's performance of his functions as a senior
          executive officer of the Company, the Executive shall not,
          throughout the Term of this Agreement and thereafter, disclose to
          any third party or use or authorize any third party to use, any
          information relating to the business, business plans, trade
          secrets or other interests of the Company (including customers
          and clients of the Company) which is confidential and valuable to
          the Company or AEC or any of their subsidiaries or any third
          party (including customers and clients of the Company) and which
          is not known to the public (the "Confidential Information"). The

          Agreement, the Confidential Information, when entrusted to the
          Executive's custody, shall be deemed to remain at all times in
          the Company's sole possession and control. Notwithstanding the
          foregoing, the Executive may, after prior written notice to the
          Company (to the extent such notice is possible under the
          circumstances) disclose such Confidential Information pursuant to
          subpoena or other legal process, and promptly thereafter shall
          advise the Company in writing as to the Confidential Information
          which was disclosed and the circumstances of such disclosure.

                    5.02  Return of Documents.  The Executive agrees that,
                          -------------------

          reason, he shall forthwith deliver up to the Company any and all
          documents and other material, recorded or stored in any medium or
          by any method, and all copies thereof, in his possession or under
          his control relating to any Confidential Information which is
          otherwise the property of the Company.

                    5.03  Non-Competition.  The Executive recognizes that
                          ---------------
          the services to be performed by him for the Company are special
          and unique.  The Executive further recognizes that the nature of
          the Company's business is such that the Executive will have full
          knowledge of the Company's business plans and practices.  The
          parties therefore confirm that, in order to protect the Company's
          goodwill, and in consideration of the Company entering into this
          Agreement, providing for a fixed term of employment of the
          Executive, the Executive does hereby agree that he will not in
          the United States of America and/or the Federal Republic of
          Germany for a period of two (2) years after he ceases to be
          employed by the Company, become employed by, a consultant or a
          Director of or hold any equity interest as a partner, member or
          shareholder (to the extent of 5% or more of the equity interest
          thereof), of any sole proprietorship, partnership, joint venture,
          corporation, or other business entity which engages in a business
          directly competitive to any business that the Company is engaged
          (or has formulated plans to engage) in at the time of termination
          of this Agreement.  This Section shall not be applicable if the
          Executive terminates this Agreement pursuant to Section 6.04
          hereof or if the Company terminates this Agreement pursuant to
          Section 6.03 hereof.

                    5.04  Remedies.  The Executive agrees that any breach
                          --------
          or threatened breach by him of any provision of this Section 5
          shall entitle the Company, in addition to any other legal
          remedies available to it, to apply to any court of competent
          jurisdiction to enjoin such breach or threatened breach.  The
          parties understand and intend that each restriction agreed to by
          the Executive hereinabove shall be construed as separable and
          divisible from every other restriction, and that the
          unenforceability, in whole or in part, of any restriction, will
          not affect the enforceability of remaining restrictions, and that
          one or more or all of such restrictions my be enforced in whole
          or in part as the circumstances warrant.  No waiver of any one
          breach of the restrictions contained in this Section 5 shall be
          deemed a waiver of any future breach.

          examination and certification by a physician selected by the
          Company subject to the Executive's approval, which approval shall
          not be unreasonably withheld.  The Executive agrees to submit
          timely to any required medical or other examination, provided
          that such examination shall be conducted at a location convenient
          to the Executive and that if the examining physician is other
          than the Executive's personal physician, the Executive shall have
          the right to have such personal physician present at such
          examination.

                    (b)  If the Executive is determined to be disabled
          pursuant to this Section 6.01, the Company shall have the option

          amounts otherwise to be paid or distributed to the Executive by
          the Company) (such amounts collectively the "Section 6.06
          Payment") would result in the application of an excise tax under
          Section 4999 of the Code, or any successor or similar provision
          thereto, the Section 6.06 Payment shall not be paid or
          distributed in the amounts or at the times otherwise required by
          this Agreement, but shall instead be paid or distributed

          date and thereafter on each anniversary thereof, in the maximum
          substantially equal amounts and over the minimum number of years
          that are determined to be required to reduce the aggregate
          present value of Section 6.06 Payment to an amount that will not

          value shall be determined in accordance with Section 280G(d)(4)
          of the Code.
