      other
      act of dishonesty by Executive; (2) any material breach by Executive of any
      provision of this Agreement which breach is not cured within a reasonable time

      Executive by TELKONET; (3) any habitual neglect of duty or misconduct of
      Executive in discharging any of his duties and responsibilities under this
      Agreement after a written demand for performance was delivered to Executive
      that
      specifically identified the manner in which the Board believed the Executive
      had
      failed to discharge his duties and responsibilities, and the Executive failed
      to
      resume substantial performance of such duties and responsibilities on a
      continuous basis immediately following such demand; (4) commission by Executive
      of a felony or any offense involving moral turpitude; or (5) any default of

      to TELKONET employees, which default, failure or refusal is not cured within
      a
      reasonable time (but not to exceed thirty (30) days) after written notification
      thereof to Executive by TELKONET. If cause exists for termination, Executive
      shall be entitled to no further compensation, except for accrued leave and
      vacation and except as may be required by applicable law.





(d)  “Good
      reason” exists for Executive to terminate his employment with TELKONET. For

      (3) Executive’s principal place of employment is actually or constructively
      moved to any office or other location 50 miles or more outside of Milwaukee,
      Wisconsin. If Executive terminates his employment with TELKONET for “good
      reason,” then, upon notice to TELKONET by Executive of such termination,
      TELKONET shall continue to pay Executive's base salary and provide Executive
      with continued participation in each employee benefit plan in which Executive
      participated immediately prior to the termination date for the period starting
      on the first day after the termination date and ending upon the expiration
      of
      the Term.





If
      Executive is terminated by TELKONET for any reason other than for “cause,” then

      In
      the event TELKONET fails to renew this Agreement upon expiration of the Term,
      then TELKONET shall continue to pay Executive's base salary and provide
      Executive with continued participation in each employee benefit plan in which

      whatever nature that Executive may have or produce during the term of
      Executive’s employment under this Agreement that pertain or relate to the then
      current business of TELKONET (the “Creations”), whether conceived by Executive
      alone or with others and whether or not conceived during regular working hours.

      discoveries.





**9.**  **Trade
      Secrets, Non-Competition and Non-Solicitation** **.**





(a)  Trade
      Secrets .
      Contemporaneous with the execution of this Agreement and during the term of
      employment under this Agreement, TELKONET shall deliver to Executive or permit
      Executive to have access to and become familiar with various confidential
      information and trade secrets of TELKONET, including without limitation, data,
      production methods, customer lists, product format or developments, other
      information concerning the business of TELKONET and ETHOSTREAM, and other unique
      processes, procedures, services and products of ETHOSTREAM and TELKONET, which
      are regularly used in the operation of the business of the ETHOSTREAM and
      TELKONET, (collectively, the “Confidential Information”). For purposes of the
      preceding sentence, information is not treated as being Confidential Information
      if it: (i) is or becomes generally available to the public other than by
      Executive in violation of this Agreement; (ii) is obtained by Executive in
      good
      faith from a third party who discloses such information to Executive on a
      non-confidential basis without violating any obligation of confidentiality
      or
      secrecy relating to the information disclosed; (iii) is independently developed
      by Executive outside the scope of his employment without use of Confidential
      Information; or (iv) is Executive’s personnel information. Executive shall not
      disclose any of the Confidential Information that he receives from ETHOSTREAM,
      TELKONET or their clients and customers in the course of his employment with
      TELKONET, directly or indirectly, nor use it in any way, either during the
      term
      of this Agreement or for a period of five (5) years thereafter, except as
      required in the course of employment with TELKONET. Executive further
      acknowledges and agrees that Executive owes ETHOSTREAM and TELKONET, a fiduciary
      duty to preserve and protect all Confidential Information from unauthorized
      disclosure or unauthorized use. All files, records, documents, drawings,
      graphics, processes, specifications, equipment and similar items relating to
      the
      business of ETHOSTREAM and/or TELKONET, whether prepared by Executive or
      otherwise coming into Executive’s possession in the course of his employment
      with TELKONET, shall remain the exclusive property of TELKONET and shall not
      be
      removed from the premises of ETHOSTREAM and/or TELKONET without the prior
      written consent of TELKONET unless removed in relation to the performance of
      Executive’s duties under this Agreement. Any such files, records, documents,
      drawings, graphics, specifications, equipment and similar items, and any and
      all
      copies of such materials which have been removed from the premises of TELKONET,
      shall be returned by Executive to ETHOSTREAM.





4


(b)  Non-Competition .
      Executive acknowledges that he will be provided with and have access to the
      Confidential Information, the unauthorized use or disclosure of which would
      cause irreparable injury to TELKONET, that TELKONET’s willingness to enter into
      this Agreement is based in material part on Executive’s agreement to the
      provisions of this Section  9(b) and that
      Executive’s breach of the provisions of this Section would materially and
      irreparably damage TELKONET. In consideration for TELKONET’s disclosure of
      Confidential Information to Executive, Executive’s access to the Confidential
      Information, and the salary paid to executive by ETHOSTREAM hereunder, Executive
      agrees that during the term of Executive’s employment with ETHOSTREAM under this
      Agreement and for one (1) year after the termination of Executive’s employment
      and regardless whether such termination is with or without cause, Executive
      shall not, directly or indirectly, either as an executive, employee, employer,
      consultant, agent, principal, partner, stockholder, corporate officer, director,
      advisor or in any other individual or representative capacity, engage or
      participate in any business that is in competition in any manner whatsoever
      with
      the Restricted Business (as defined herein) in North America. “Restricted
      Business” means any business conducted by TELKONET, either itself or through
      ETHOSTREAM, at any time prior to or during Executive’s employment pursuant to
      this Agreement.





(c)  Reasonableness
      of Restrictions .
      Executive acknowledges that the restrictions set forth in Section
      9(b) of this
      Agreement are reasonable in scope and necessary for the protection of the
      business and goodwill of TELKONET. Executive agrees that should any portion
      of
      the covenants in Section
      9 be
      unenforceable because of the scope thereof or the period covered thereby or
      otherwise, the covenant shall be deemed to be reduced and limited to enable
      it
      to be enforced to the maximum extent permissible under the laws and public
      policies applied in the jurisdiction in which enforcement is
      sought.





(d)  Soliciting
      Executives .
      Executive shall not during the term of this Agreement or for a period of one
      (1)
      year after termination of Executive’s employment hereunder for any reason,
      whether by resignation, discharge or otherwise, either directly or indirectly,
      solicit the employment of, any employee of ETHOSTREAM or TELKONET for the
      purpose of causing them to leave the employment of ETHOSTREAM or TELKONET or
      take employment with any business that is in competition in any manner
      whatsoever with the business of ETHOSTREAM or TELKONET.





5


(e)  Injunctive
      Relief; Extension of Restrictive Period .
      In the
      event of a breach of any of the covenants by Executive or TELKONET contained
      in
      this Agreement, it is understood that damages will be difficult to ascertain,
      and either party may petition a court of law or equity for injunctive relief
      in
      addition to any other relief which Executive or TELKONET may have under the
      law,
      including but not limited to reasonable attorneys’ fees.





**10.**  **Miscellaneous** **.**





(a)  This
      Agreement shall be binding upon the parties and their respective heirs,
      executors, administrators, successors and assigns. Executive shall not assign
      any part of his rights under this Agreement without the prior written consent
      of
      TELKONET.





(b)  This
      Agreement contains the entire agreement and understanding between the parties
      and supersedes any and all prior understandings and agreements between the
      parties regarding Executive’s employment.





(c)  No
      modification hereof shall be binding unless made in writing and signed by the
      party against whom enforcement is sought. No waiver of any provisions of this
      Agreement shall be valid unless the same is in writing and signed by the party
      against whom it is sought to be enforced, unless it can be shown through custom,
      usage or course of action.





(d)  This
      Agreement is executed in, and it is the intention of the parties hereto that
      it
      shall be governed by, the laws of the State of Wisconsin without giving effect
      to applicable conflict of laws provisions.





(e)  The
      provisions of this Agreement shall be deemed to be severable, and the invalidity
      or unenforceability of any provision shall not affect the validity or
      enforceability of the other provisions hereof.
