          the  Executive  shall be based at the  offices of the  Company at 1000
          East Main  Street,  Plainfield,  Indiana,  and,  except  for  required
          business travel to an extent substantially consistent with the present
          business  travel  obligations  of  executives  of the Company who have
          positions  of  authority  comparable  to  that of the  Executive,  the
          Executive  shall not be required to relocate to a new principal  place

          such upward  adjustments  in the Annual Base Salary as the Board deems
          to be necessary or desirable, including without limitation adjustments
          in order to reflect  increases in the cost of living.  Any increase in
          the Annual  Base  Salary  shall not serve to limit or reduce any other

          shall  not  be  reduced   after  any  increase   thereof   except  for
          across-the-board  salary reductions similarly affecting all management

4.   Termination of Employment.

     a.   Death. The Executive's  employment shall terminate  automatically upon

     b.   By the Company for Cause.  The Company may terminate  the  Executive's
          employment  during the  Employment  Period for Cause.  For purposes of
          this Agreement, "Cause" shall mean: 

          (i)  The  willful  and   continued   failure  by  the   Executive   to
               substantially  perform  the  Executive's  duties with the Company
               (other  than  any  such  failure   resulting   from   Executive's
               incapacity due to physical or mental  illness) or any such actual
               or  anticipated  failure  after  the  issuance  of  a  Notice  of
               Termination for Good Reason by the Executive  pursuant to Section
               4(c)  after a  written  demand  for  substantial  performance  is
               delivered   to  the   Executive   by  the  Board,   which  demand
               specifically  identifies  the manner in which the Board  believes
               that  the   Executive   has  not   substantially   performed  the
               Executive's duties, or

               The breach by the Executive of the confidentiality provisions set
               forth in Section 8 of this Agreement, or

          (iii)The  conviction of the Executive for the  commission of a felony,
               including the entry of a guilty or nolo  contendere  plea, or any
               willful or grossly  negligent action or inaction by the Executive
               that  has  a   materially   adverse   effect   on  the   Company.
             
               For purposes of this definition of "Cause," no act, or failure to
               act, on the  Executive's  part shall be deemed  "willful"  unless
               done,  or omitted to be done,  by the Executive not in good faith
               and  without  reasonable  belief  that the  Executive's  act,  or
               failure  to  act,  was  in the  best  interest  of  the  Company.
               Notwithstanding the above definition of "Cause",  the Company may
               terminate the Executive's employment during the Employment Period
               for a reason other than Cause,  but the  obligations  placed upon
               the Company in Section 5 shall apply.

     c.   By the  Executive  for Good Reason.  The  Executive  may terminate his
          employment during the Employment Period for Good Reason.  For purposes
          of     this      Agreement,      "Good     Reason"     shall     mean:
 
          (i)  The reduction in the Executive's  Annual Base Salary as specified
               in  Section  3(a) of this  Agreement,  or any  other  benefit  or
               payment  described  in  Section 3 of this  Agreement,  except for
               across-the-board   salary  reductions   similarly  affecting  all
               management personnel of Cinergy, Cinergy Services, CG&E, and PSI,
               and  changes to the  employee  benefits  programs  affecting  all
               management  personnel of those  corporations,  provided that such
               changes (either individually or in the aggregate) will not result
               in a material  adverse  change with respect to the benefits which
               the Executive was entitled to receive as of the Effective Date;

          (ii) The  material  reduction  without his consent of the  Executive's
               title, authority, duties or responsibilities from those in effect
               immediately prior to the reduction;

          (iii)Any  breach  by the  Company  of  any  other  material  provision
               (including  but  not  limited  to the  place  of  performance  as
               specified in Section 2(b);

          (iv) The  Executive's  disability due to physical or mental illness or
               injury which  precludes the Executive from performing any job for
               which  he is  qualified  and  able  to  perform  based  upon  his
               education, training or experience; or

          (v)  Any event which  constitutes  a "Change in Control" as defined in
               Section 4(f) of this Agreement.

     d.   Notice of Termination. Any termination by the Company for Cause, or by
          the  Executive  for Good Reason,  shall be  communicated  by Notice of
          Termination to the other party to this  Agreement  given in accordance
          with Section 10(b) of this Agreement.  For purposes of this Agreement,
          a   "Notice   of   Termination"   means  a   written   notice   which:

          (i)  Indicates the specific  termination  provision in this  Agreement
               relied upon;

          (ii) To the extent  applicable,  sets forth in  reasonable  detail the
               facts  and   circumstances   claimed   to  provide  a  basis  for

               indicated; and

          (iii)If the Date of Termination  (as defined in Section 4(e)) is other
               than  the  date  of  receipt  of  such  notice,   specifies   the
               termination  date  (which date shall be not more than thirty (30)
               days  after  the  giving  of such  notice).  The  failure  by the
               Executive   or  the  Company  to  set  forth  in  the  Notice  of
               Termination  any fact or  circumstances  which  contributes  to a
               showing of Good  Reason or Cause shall not waive any right of the
               Executive  or the Company  under this  Agreement  or preclude the
               Executive   or  the   Company   from   asserting   such  fact  or
               circumstances  in  enforcing  the  Executive's  or the  Company's
               rights under this Agreement.

     e.   Date of Termination. "Date of Termination" means:

          (i)  If the  Executive's  employment  is terminated by the Company for

               as the case may be;

          (ii) If the Executive's  employment is terminated by the Company other
               than for  Cause,  the  date on which  the  Company  notifies  the
               Executive of such termination; and

5.   Obligations of the Company Upon Termination.

     a.   Certain  Terminations.  During the Employment  Period,  if the Company

                    (together with any accrued interest or earnings thereon) and
                    any  accrued  vacation  pay,  in each case to the extent not
                    previously paid.

                    (The amounts specified in clauses (1), (2), and (3) shall be
                    referred to in this Agreement as the "Accrued Obligations".)
                    The amounts  specified in this Section 5(a)(i) shall be paid
                    within thirty (30) days after the Date of  Termination.  The
                    Accrued Obligations described in this Section are payable to
                    the Executive  regardless of whether a Change in Control has
                    occurred.

               (ii) Prior to the  occurrence of a Change in Control,  and in the
                    event of Termination other than by reason of the Executive's
                    death, then:

                    (1)  the  Company  shall  pay to the  Executive  a lump  sum
                         amount,  in cash, equal to the present value discounted
                         using  an  interest   rate  equal  to  the  prime  rate
                         promulgated  by CitiBank,  N.A. and in effect as of the
                         Date of  Termination  (the "Prime  Rate") of the Annual
                         Base  Salary,  and the Cinergy  Annual  Incentive  Plan
                         target  percentage  payable  through  the  end  of  the
                         Employment Period, each at the rate, and using the same
                         goals and  factors,  in  effect  at the time  Notice of
                         Termination is given,  and paid within thirty (30) days
                         of the Date of Termination;

                    (2)  the  Company  shall pay to the  Executive  the  present
                         value  (discounted at the Prime Rate) of all amounts to
                         which the  Executive  would have been  entitled  had he
                         remained in  employment  with the Company until the end
                         of the  Employment  Period under the Cinergy  Executive
                         Supplemental Life Insurance Program;

                    (3)  the Company shall pay to the Executive the value of all
                         deferred  compensation  amounts  whether  or  not  then
                         payable; and

                    (4)  the  Company  shall  continue,  until  the  end  of the
                         Employment Period,  medical and welfare benefits to the
                         Executive and/or the Executive's  family at least equal
                         to  those  which  would  have  been   provided  if  the
                         Executive's   employment   had  not   been   terminated
                         (excluding  benefits to which the  Executive has waived
                         his  rights  in  writing),   such  benefits  to  be  in
                         accordance with the most favorable  medical and welfare
                         benefit  plans,  practices,  programs or policies  (the
                         "M&W Plans") of the Company as in effect and applicable
                         generally to other senior executives of the Company and
                         their  families  during  the  ninety  (90)  day  period
                         immediately   preceding   the   Date  of   Termination;
                         provided,   however,  that  if  the  Executive  becomes
                         employed  with  another  employer  and is  eligible  to
                         receive medical or other welfare benefits under another
                         employer-provided  plan,  the  benefits  under  the M&W
                         Plans shall be secondary to those  provided  under such
                         other   plan   during   such   applicable   period   of
                         eligibility.

               (iii)From and after the  occurrence of a Change in Control and in
                    the  event  of  Termination  other  than  by  reason  of the
                    Executive's  death,  then  in  lieu  of any  further  salary
                    payments to the Executive for periods subsequent to the Date
                    of  Termination  and in lieu of any other  benefits  payable
                    pursuant to Section 5(a)(ii) of this Agreement:

                    (1)  The  Company  shall  pay to the  Executive  a lump  sum
                         severance payment, in cash, equal to the greater of:

                    (A)  the  present  value of all amounts  and  benefits  that
                         would  have been due under  Sections  5(a)(ii)  of this
                         Agreement, excluding Section 5(a)(ii)(4), and

                    (B)  three  (3)  times  the  sum of (x)  the  higher  of the
                         Executive's  Annual Base  Salary in effect  immediately
                         prior to the  occurrence  of the event or  circumstance
                         upon  which the  Notice of  Termination  is based or in
                         effect immediately prior to the Change in Control,  and
                         (y) the  higher  of the  amount  paid to the  Executive
                         pursuant to all incentive  compensation  or bonus plans
                         or  programs  maintained  by the  Company,  in the year
                         preceding that in which the Date of Termination  occurs
                         or in the year  preceding  that in which the  Change in
                         Control occurs; and

                    (2)  For a  thirty-six  (36) month  period after the Date of
                         Termination,  the Company  shall arrange to provide the
                         Executive  with life,  disability,  accident and health
                         insurance benefits substantially similar to those which
                         the  Executive  is receiving  immediately  prior to the
                         Notice of  Termination  (without  giving  effect to any
                         reduction in such  benefits  subsequent  to a Change in
                         Control  which  reduction   constitutes  Good  Reason),
                         except  for  any  benefits  that  were  waived  by  the
                         Executive in writing.  Benefits otherwise receivable by
                         the  Executive  pursuant to this  Section  5(a)(iii)(2)
                         shall be reduced to the extent comparable  benefits are
                         actually received by or made available to the Executive
                         without  cost during the  thirty-six  (36) month period
                         following  the  Executive's  termination  of employment
                         (and  any  such  benefits   actually  received  by  the
                         Executive  shall  be  reported  to the  Company  by the
                         Executive).

                    The  Executive's  employment  shall be  deemed  to have been
                    terminated  following a Change in Control of Cinergy without
                    Cause or by the Executive for Good Reason if, in addition to
                    all   other   applicable   Terminations,   the   Executive's
                    employment  is  terminated  prior  to a  Change  in  Control
                    without  Cause at the  direction of a Person who has entered
                    into an agreement with Cinergy or any of its subsidiaries or
                    affiliates,  the  consummation  of which will  constitute  a
                    Change  in  Control  or  if  the  Executive  terminates  his
                    employment  for Good Reason  prior to a Change in Control if
                    the  circumstances  or event which  constitutes  Good Reason
                    occurs at the direction of such Person.

     b.   Termination  by the Company for Cause or by the  Executive  Other Than
          for Good  Reason.  Subject  to the  provisions  of  Section  7 of this
          Agreement, if the Executive's employment shall be terminated for Cause
          during  the  Employment   Period,  or  if  the  Executive   terminates
          employment  during the Employment  Period other than a termination for
          Good  Reason,  the Company  shall have no further  obligations  to the
          Executive under this Agreement other than the obligation to pay to the
          Executive the Accrued  Obligations  and the amounts  determined  under
          Section 5(c), plus any other earned but unpaid  compensation,  in each
          case to the extent not previously paid.

     c.   Retirement Benefits on Termination. In addition to retirement benefits
          under  Cinergy's  Non-Union  Employees'  Pension Plan,  and its Excess
          Pension  Plan,  or any  successor  thereto,  the  Executive  shall  be
          eligible to participate in the Senior Executive  Supplement portion of
          Cinergy's  Supplemental Executive Retirement Plan effective January 1,
          1999. 

     d.   Survival of Section 5(c). The provisions of Section 5(c) shall survive
          the expiration or termination of this Agreement for any reason.

     e.   Certain  Tax  Consequences.  In the event that the  Executive  becomes
          entitled to the payments and benefits described in this Section 5 (the
          "Severance  Benefits"),  if any  of the  Severance  Benefits  will  be
          subject to any excise tax (the "Excise  Tax")  imposed  under  Section
          4999 of the Internal  Revenue Code of 1986,  as amended (the  "Code"),
          the  Company  shall pay to the  Executive  an  additional  amount (the
          "Gross-Up   Payment")  such  that  the  net  amount  retained  by  the
          Executive,  after deduction of an Excise Tax on the Severance Benefits
          and any federal,  state and local income and employment tax and Excise
          Tax upon the payment provided for by this Section 5, shall be equal to
          the Severance Benefits. For purposes of determining whether any of the
          Severance Benefits will be subject to the Excise Tax and the amount of
          such Excise Tax,

          (i)  any other payments or benefits  received or to be received by the
               Executive  in  connection   with  a  Change  in  Control  or  the
               Executive's  termination of employment  (whether  pursuant to the
               terms  of  this  Agreement  or any  other  plan,  arrangement  or
               agreement with the Company,  any Person whose actions result in a
               Change in Control or any Person  affiliated  with the  Company or
               such Person) shall be treated as "parachute  payments" within the
               meaning  of  Section  280G(b)(2)  of the  Code,  and all  "excess
               parachute  payments" within the meaning of Section  280G(b)(1) of
               the Code shall be treated as subject to the Excise Tax, unless in
               the opinion of tax counsel selected by the Company's  independent
               auditors and  reasonably  acceptable to the Executive  such other
               payments  or  benefits  (in  whole or in part) do not  constitute
               parachute payments,  including by reason of Section 280G(b)(4)(A)
               of the Code,  or such excess  parachute  payments (in whole or in
               part) represent  reasonable  compensation  for services  actually
               rendered,  within the  meaning of  Section  280G(b)(4)(B)  of the
               Code,  in  excess  of the  Base  Amount  as  defined  in  Section
               280G(b)(3) of the Code allocable to such reasonable compensation,
               or are otherwise not subject to the Excise Tax,

          (ii) the  amount of the  Severance  Benefits  that shall be treated as
               subject to the Excise Tax shall be equal to the lesser of

               (1)  the total amount of the Severance Benefits, or

               (2)  the amount of excess  parachute  payments within the meaning
                    of Section  280G(b)(1)  of the Code (after  applying  clause
                    (i), above), and

          (iii)the value of any  non-cash  benefits or any  deferred  payment or
               benefit shall be determined by the Company's independent auditors
               in accordance  with the principles of Section  280G(d)(3) and (4)
               of the  Code.  For  purposes  of  determining  the  amount of the
               Gross-Up  Payment,  the Executive  shall be deemed to pay federal
               income  taxes at the  highest  marginal  rate of  federal  income
               taxation in the calendar year in which the Gross-Up Payment is to
               be made and state and local income taxes at the highest  marginal
               rate of  taxation in the state and  locality  of the  Executive's
               residence  on  the  Date  of  Termination,  net  of  the  maximum
               reduction in federal  income  taxes which would be obtained  from
               deduction  of such state and local  taxes.  In the event that the
               Excise Tax is subsequently  determined to be less than the amount
               taken into account  hereunder at the time of  termination  of the
               Executive's employment, the Executive shall repay to the Company,
               at the time that the  amount of such  reduction  in Excise Tax is
               finally   determined,   the  portion  of  the  Gross-Up   Payment
               attributable to such reduction (plus that portion of the Gross-Up
               Payment  attributable  to the Excise Tax and  federal,  state and
               local income and employment  tax imposed on the Gross-Up  Payment
               being repaid by the  Executive to the extent that such  repayment
               results in a reduction  in Excise Tax and/or a federal,  state or
               local income or employment  tax  deduction)  plus interest on the
               amount  of  such  repayment  at  the  rate  provided  in  Section
               1274(b)(2)(B)  of the Code.  In the event  that the Excise Tax is
               determined  to exceed the amount taken into account  hereunder at
               the  time  of  the  termination  of  the  Executive's  employment
               (including  by reason of any payment the  existence  or amount of
               which cannot be determined at the time of the Gross-Up  Payment),
               the Company shall make an additional  Gross-Up Payment in respect
               of such excess (plus any interest, penalties or additions payable
               by the  Executive  with  respect to such excess) at the time that
               the amount of such excess is finally  determined.  The  Executive
               and the Company shall each reasonably cooperate with the other in
               connection  with  any  administrative  or  judicial   proceedings
               concerning  the  existence or amount of liability  for Excise Tax
               with respect to the Severance Benefits.

     f.   Value Creation Plan and Stock Options.  Upon termination of employment
          for any reason,  the Executive's  entitlement to restricted shares and
          performance  shares under the Value  Creation Plan of the Cinergy 1996
          Long-Term  Incentive  Compensation  Plan and any stock options granted
          under the Cinergy  Stock  Option Plan or the  Cinergy  1996  Long-Term
          Incentive  Compensation  Plan shall be  determined in reference to the
          terms  of  the   appropriate   plan,  any  applicable   administrative
          guidelines  and written  agreements  (all such  plans,  administrative
          guidelines  and  written  agreements  referred  to in  this  Agreement
          collectively as the "Stock-Related Documents").

     g.   Other Fees and  Expenses.  The Company also shall pay to the Executive
          all legal fees and expenses incurred by the Executive as a result of a
          termination  which  entitles the Executive to the  Severance  Benefits
          (including all such fees and expenses,  if any,  incurred in disputing
          any such  termination or in seeking in good faith to obtain or enforce
          any benefit or right provided by this Agreement).  Such payments shall
          be  made  within  five  (5)  business  days  after   delivery  of  the
          Executive's   written  requests  for  payment  accompanied  with  such
          evidence of fees and expenses  incurred as the Company  reasonably may
          require.

6.   Non-exclusivity of Rights. Nothing in this Agreement shall prevent or limit
     the Executive's  continuing or future  participation in any benefit,  plan,
     program,  policy or  practice  provided  by the  Company  and for which the
     Executive  may  qualify  (except  with  respect to any benefit to which the
     Executive  has waived his rights in  writing),  nor shall  anything  herein
     limit or otherwise  affect such rights as the  Executive may have under any
     other  contract or  agreement  entered  into after the date hereof with the
     Company.  Amounts  which are  vested  benefits  or which the  Executive  is
     otherwise entitled to receive under any benefit,  plan, program,  policy or
     practice  of, or any  contract  or  agreement  entered  into after the date
     hereof with, the Company at or subsequent to the Date of Termination, shall
     be  payable in  accordance  with such  benefit,  plan,  program,  policy or
     practice,  or contract or agreement,  except as explicitly modified by this
     Agreement.

7.   Full Settlement: Mitigation. Except as provided in Sections 5(a)(ii)(4) and
     5(a)(iii)(2)  of this  Agreement,  the  Company's  obligation  to make  the
     payments  provided  for in this  Agreement  and  otherwise  to perform  its
     obligations  under this  Agreement  shall not be affected  by any  set-off,
     counterclaim, recoupment, defense or other claim, right or action which the
     Company may have  against the  Executive  or others.  In no event shall the
     Executive be obligated to seek other employment or take any other action by
     way of mitigation of the amounts (including amounts for damages for breach)
     payable to the Executive  under any of the provisions of this Agreement and
     such  amounts  shall not be reduced  whether or not the  Executive  obtains
     other  employment.  If the Executive  finally  prevails with respect to any
     dispute   between  the  Company,   the   Executive  or  others  as  to  the
     interpretation, terms, validity or enforceability of (including any dispute
     about the amount of any payment  pursuant to) this  Agreement,  the Company
     agrees  to pay  all  legal  fees  and  expenses  which  the  Executive  may
     reasonably incur as a result of any such dispute.

8.   Arbitration.  The parties  agree that any dispute,  claim,  or  controversy
     based on common law,  equity,  or any  federal,  state,  or local  statute,
     ordinance,  or regulation (other than workers' compensation claims) arising
     out of or relating  in any way to the  Executive's  employment,  the terms,
     benefits, and conditions of employment, or concerning this Agreement or its
     termination and any resulting termination of employment,  including whether
     such dispute is arbitrable, shall be settled by arbitration. This agreement
     to  arbitrate  includes  but is not  limited  to all claims for any form of
     illegal discrimination,  improper or unfair treatment or dismissal, and all
     tort  claims.   The   Executive   shall  still  have  a  right  to  file  a
     discrimination  charge  with a  federal  or  state  agency,  but the  final
     resolution of any  discrimination  claim shall be submitted to  arbitration
     instead of a court or jury. The arbitration  proceeding  shall be conducted
     under the employment dispute  resolution  arbitration rules of the American
     Arbitration  Association  in  effect at the time a demand  for  arbitration
     under the  rules is made.  The  decision  of the  arbitrator(s),  including
     determination  of the amount of any damages  suffered,  shall be exclusive,
     final, and binding on all parties, their heirs, executors,  administrators,
     successors  and  assigns.  Each party  shall bear its own  expenses  in the
     arbitration for  arbitrators'  fees and attorneys' fees, for its witnesses,
     and for other expenses of presenting  its case.  Other  arbitration  costs,
     including administrative fees and fees for records or transcripts, shall be
     borne equally by the parties.

     as well as all  successors and assigns  thereof (the "Cinergy  Companies"),
     all secret,  confidential  information,  knowledge or data  relating to the
     Cinergy Companies,  and their respective  businesses,  that shall have been

     required  from  time to time to make  public  disclosure  of the  terms  or
     existence of the  Executive's  employment  relationship  in order to comply
     with various laws and legal requirements. In addition to all other remedies
