           RESULTS OF OPERATIONS FOR THE QUARTER ENDED MARCH 31, 1999

Operating Revenues

Electric Operating Revenues

The  components  of electric  operating  revenues  and the related kwh sales are
shown below:

                                                 Quarter Ended
                                                    March 31                
                                       Revenue               Kwh Sales

                                            ($ and kwh in millions)

Retail                            $676      $  633      12,276      11,678
Sales for resale                   266         515      10,694      21,733
Other                               27          11         172        -

Total                             $969      $1,159      23,142      33,411

Electric  operating  revenues decreased $190 million (16%) for the quarter ended
March 31, 1999,  when  compared to the same period for 1998.  This  decrease was
primarily  due  to  decreased   volumes  on  non-firm  power  sales  for  resale
transactions  related to energy  marketing  and  trading  operations.  Partially
offsetting  the decline was an increase in the average  price per kwh for retail
customers,  higher retail and firm power kwh sales  resulting from growth in the
average  number of  residential  and  commercial  customers and a return to more
normal  weather in the first quarter of 1999, as compared to 1998, and increased
international operations.

Gas Operating Revenues

The  components  of gas  operating  revenues and the related mcf sales are shown
below:

                                                Quarter Ended
                                                   March 31

Transportation                     20             11       13            16
                                 ----           ----      ---           ---
Total                            $421           $185      182            42

Gas operating revenues increased $236 million in the first quarter of 1999, when
compared  to the same  period  last  year,  primarily  due to the gas  operating
revenues of ProEnergy, which was acquired in June 1998. A lower average cost per
mcf of gas  purchased,  which was  passed on to end  users,  contributed  to the
decrease in retail sales.  Transportation revenues increased as more residential
and commercial  customers began to purchase gas directly from  suppliers,  using
transportation  services  provided  by CG&E.  This  increase  in  transportation
revenues  was  partially  offset by a  decrease  in mcf  transportation  volumes
resulting from the loss of a large  industrial  transportation  customer  during
late 1998.

Other Revenues

Other revenues  increased $8 million for the quarter ended March 31, 1999,  over
the same period of 1998.  This  increase was  primarily  the result of increased
revenues of new  non-regulated  initiatives  operated  by the  various  business
units.

Operating Expenses

Fuel and Purchased and Exchanged Power

The components of fuel and purchased and exchanged power are shown below:

                                              Quarter Ended
                                                 March 31

Purchased and exchanged power                235         471
                                            ----        ----
Total                                       $433        $652

Electric  fuel costs  increased $17 million (9%) for the quarter ended March 31,
1999, as compared to the same period last year.

An analysis of these fuel costs is shown below:

                                              Quarter Ended
                                                 March 31   
                                              (in millions)

Fuel expense - March 31, 1998                     $181 
Increase (Decrease) due to change in:
  Price of fuel                                     (2)
  Deferred fuel cost                                 5
  Kwh generation                                     9
  Other                                              5
                                                  ----

Fuel expense - March 31, 1999                     $198

Purchased  and  exchanged  power  expense  decreased  $236 million (50%) for the
quarter  ended  March 31,  1999,  as  compared  to the same  period  last  year,
primarily  reflecting decreased purchases of non-firm power for resale to others
as a result of a decline in sales for resale volumes in the energy marketing and
trading operations.

Gas Purchased

Gas purchased for the quarter ended March 31, 1999, increased $227 million, when
compared  to the same  period  last  year,  primarily  due to the gas  purchased
expenses of  ProEnergy,  which was acquired in June 1998.  Partially  offsetting
this increase was a lower average cost per mcf of gas purchased.

                                         Quarter Ended
                                            March 31   
                                         1999     1998
                                         (in millions)

Other operation                          $195     $174
Maintenance                                50       39
                                         ----     ----
Total                                    $245     $213


Other operation expenses increased $21 million (12%) for the quarter ended March
31, 1999, as compared to the same period last year, primarily due to an increase
in operating  expenses  related to various  non-regulated  subsidiaries  and the
estimated loss on a specific customer account.

Maintenance expenses increased $11 million (28%) for the quarter ended March 31,
1999,  as compared to the same period of 1998,  primarily  due to an increase in
maintenance  activities  associated with planned  outages at certain  production
facilities.

Depreciation and Amortization

The components of depreciation and amortization expenses are shown below:

                                        Quarter Ended
                                           March 31   
                                        1999     1998
                                        (in millions)

Depreciation                            $79      $73
Amortization of phase-in deferrals        6        6

  deferred operating expenses             1        1
                                        ---      ---
Total                                   $86      $80

Depreciation  expense  increased $6 million (8%) for the quarter ended March 31,
1999,  as compared to the same period last year,  primarily  due to additions to
depreciable plant.

Equity in Earnings of Unconsolidated Subsidiaries

The $33 million  increase in equity in earnings of  unconsolidated  subsidiaries
for the quarter ended March 31, 1999, as compared to the same period of 1998, is
primarily  attributable to an increase in the earnings of Avon Energy  resulting
from increased  profits related to Midlands'  supply business and lower costs of
purchased electricity.

Preferred Dividend Requirements of Subsidiaries

The decrease in preferred  dividend  requirements  of subsidiaries of $1 million
(44%) for the quarter  ended March 31,  1999,  as compared to the same period of
1998, is primarily attributable to PSI's redemption of all outstanding shares of
its 7.44% Series Cumulative Preferred Stock on March 1, 1998.

Electric  operating  revenues decreased $111 million (19%) for the quarter ended
March 31, 1999,  when  compared to the same period for 1998.  This  decrease was
primarily  due  to  decreased   volumes  on  non-firm  power  sales  for  resale
transactions  related to  Cinergy's  energy  marketing  and trading  operations.
Partially  offsetting  the decline was higher  retail kwh sales  resulting  from
growth in the average  number of  residential  and  commercial  customers  and a
return to more normal weather in the first quarter of 1999, as compared to 1998.

Gas Operating Revenues

Gas operating  revenues  decreased $9 million (5%) in the first quarter of 1999,
when  compared to the same period last year. A lower average cost per mcf of gas
purchased,  which was passed on to end users,  contributed  to the  decrease  in
retail  sales.   Transportation  revenues  increased  as  more  residential  and
commercial  customers  began to purchase  gas  directly  from  suppliers,  using
transportation  services  provided  by CG&E.  This  increase  in  transportation
revenues  was  partially  offset by a  decrease  in mcf  transportation  volumes
resulting from the loss of a large  industrial  transportation  customer  during
late 1998.

Fuel expense - March 31, 1999                          $86

Purchased  and  exchanged  power  expense  decreased  $124 million (52%) for the
quarter  ended March 31,  1999,  as compared to the same period last year.  This
decline primarily reflects  decreased  purchases of non-firm power for resale to
others as a result of a decline in sales for resale volumes in Cinergy's  energy
marketing and trading operations.

Gas Purchased

Gas purchased for the quarter ended March 31, 1999, decreased $18 million (18%),
when compared to the same period last year,  primarily due to an decrease in the
average cost per mcf of gas purchased.

Other Operation and Maintenance

The components of other operation and maintenance expenses are shown below:

                                         Quarter Ended

Total                                    $108      $101




<PAGE>





Maintenance  expenses increased $5 million (26%) for the quarter ended March 31,
1999,  as compared to the same period of 1998,  primarily  due to an increase in
maintenance  activities  associated with planned  outages at certain  production
facilities.

Depreciation and Amortization

The components of depreciation and amortization expenses are shown below:

                                        Quarter Ended
                                           March 31

                                        (in millions)

Depreciation                            $43      $41
Amortization of phase-in deferrals        7        6
Amortization of post-in-service
  deferred operating expenses             1        1
                                        ---      ---
Total                                   $51      $48

Depreciation  expense  increased $2 million (5%) for the quarter ended March 31,
1999,  as compared to the same period of 1998,  primarily  due to  additions  to
depreciable plant.

Other Income and (Expenses) - Net

The change in other  income and  (expenses)  - net of $1 million for the quarter
ended March 31, 1999,  as compared to the same period of 1998,  is primarily due
to an increase in interest  income and an increase in allowance for equity funds
used during  construction  resulting from an increase in the equity rate applied
and an increase in construction expenditures subject to allowance.

Interest

The decrease in interest  expense of $2 million (9%) for the quarter ended March
31, 1999, as compared to the same period last year, was due to decreases in both
interest on long-term debt and other interest expense.  The decrease in interest
expense on long-term debt is primarily due to a net redemption of  approximately
$90 million of long-term  debt during the period of March 1998 through  February
1999. The decrease in other  interest  expense was due to a reduction in average
short-term borrowings and lower short-term interest rates.

                                PSI ENERGY, INC.
           RESULTS OF OPERATIONS FOR THE QUARTER ENDED MARCH 31, 1999

Operating Revenues

The components of operating revenues and the related kwh sales are shown below:

                                                Quarter Ended
                                                   March 31                  
                                         Revenue              Kwh Sales     
                                     1999       1998      1999         1998  
                                           ($ and kwh in millions)

Retail                               $318       $297      6,393        6,239
Sales for resale                      157        287      6,282       12,185
Other                                   7          8        N/A          N/A
                                     ----       ----     ------       ------
Total                                $482       $592     12,675       18,424

Operating  revenues decreased $110 million (19%) for the quarter ended March 31,
1999, when compared to the same period for 1998. This decrease was primarily due
to decreased volumes on non-firm power sales for resale transactions  related to
Cinergy's  energy  marketing and trading  operations.  Partially  offsetting the
decline was an increase in the average  price per kwh for retail  customers  and
higher  retail and firm power kwh sales  resulting  from  growth in the  average
number of  residential  and  commercial  customers  and a return to more  normal
weather in the first quarter of 1999, as compared to 1998.

Operating Expenses

Fuel and Purchased and Exchanged Power

The components of fuel and purchased and exchanged power are shown below:

                                            Quarter Ended
                                               March 31   
                                           1999       1998
                                            (in millions)

Fuel                                       $107       $ 92
Purchased and exchanged power               128        261
                                           ----       ----
Total                                      $235       $353

Fuel  costs  increased  $15  million  (16%) for the first  quarter  of 1999,  as
compared to the same period last year.

An analysis of fuel costs is shown below:

                                              Quarter Ended
                                                 March 31   
                                              (in millions)

Fuel expense - March 31, 1998                     $ 92
Increase (Decrease) due to change in:
  Price of fuel                                     (3)
  Deferred fuel cost                                12
  Kwh generation                                     6
                                                  ----

Fuel expense - March 31, 1999                     $107

Purchased  and  exchanged  power  expense  decreased  $133 million (51%) for the
quarter  ended March 31,  1999,  as compared to the same period last year.  This
decline primarily reflects  decreased  purchases of non-firm power for resale to
others as a result of a decline in sales for resale volumes in Cinergy's  energy
marketing and trading operations.

Other Operation and Maintenance

The components of other operation and maintenance expenses are shown below:

                                         Quarter Ended
                                            March 31   
                                         1999     1998
                                         (in millions)

Other operation                          $ 88     $ 82
Maintenance                                25       20
                                         ----     ----
Total                                    $113     $102

Other  operation  expense  increased $6 million (7%) for the quarter ended March
31, 1999, as compared to the same period of 1998, primarily due to the estimated
loss on a specific customer account.

Maintenance  expense  increased $5 million (25%) for the quarter ended March 31,
1999,  as compared to the same period of 1998,  primarily  due to an increase in
maintenance  activities  associated with planned  outages at certain  production
facilities.

Other Income and (Expenses) - Net

The change in other  income and  (expenses)  - net of $1 million for the quarter
ended March 31,  1999,  as compared  to the same  period of 1998,  is  primarily
attributable to a decrease in interest income.

Interest

The $2 million (7%) decrease in interest expense for the quarter ended March 31,
1999,  as compared to the same period of 1998, is primarily due to a decrease in
other  interest  expense  resulting  from  a  reduction  in  average  short-term
borrowings  and  lower  short-term  interest  rates.  Partially  offsetting  the
decrease was an increase in interest  expense on long-term  debt  resulting from
the net issuance of  approximately  $144  million of  long-term  debt during the
period from March 1998 through December 1998.

Preferred Dividend Requirement

The  decrease in  preferred  dividend  requirement  of $1 million  (48%) for the
quarter  ended  March 31,  1999,  as  compared  to the same  period of 1998,  is
primarily  attributable  to PSI's  redemption of all  outstanding  shares of its
7.44% Series Cumulative Preferred Stock on March 1, 1998.

                     THE UNION LIGHT, HEAT AND POWER COMPANY
           RESULTS OF OPERATIONS FOR THE QUARTER ENDED MARCH 31, 1999


Operating Revenues

Electric Operating Revenues

Electric  operating  revenues  increased $2 million  (5%) for the quarter  ended
March 31,  1999,  as  compared  to the same  period  last  year.  This  increase
primarily  reflects a return to more normal weather  conditions,  as compared to
the same period in 1998,  and higher retail kwh sales  resulting  from growth in
the average number of residential and commercial customers.

Gas Operating Revenues

The  components  of gas  operating  revenues and the related mcf sales are shown
below:

                                                Quarter Ended
                                                   March 31                   
                                        Revenue                Mcf Sales      
                                  1999         1998        1999         1998
                                          ($ and mcf in thousands)

Retail                          $31,555      $27,266      5,219        4,491
Transportation                    1,445        1,214      1,078        1,106
                                -------      -------      -----        -----
Total                           $33,000      $28,480      6,297        5,597

Gas operating  revenues increased $5 million (16%) in the first quarter of 1999,
when  compared to the same period last year,  primarily due to a increase in mcf
volumes sold, a return to more normal weather conditions, and an increase in the
number of customers.

Operating Expenses

Electricity Purchased from Parent Company for Resale

Electricity  purchased increased $3 million (8%) for the quarter ended March 31,
1999, as compared to the same period last year.  This increase  reflects  higher
volumes purchased from CG&E.

Gas Purchased

Gas purchased  for the quarter ended March 31, 1999,  increased $1 million (6%),
when compared to the same period last year,  primarily due to an increase in the
volumes of gas purchased,  due to higher demand and an increase in the number of
customers.

Other Operation and Maintenance

The components of other operation and maintenance expenses are shown below:

                                        Quarter Ended
                                           March 31     
                                        1999      1998  
                                        (in thousands)

Other operation                       $ 8,948    $8,135
Maintenance                             1,242     1,295 
                                      -------    -------
Total                                 $10,190    $9,430

Other operation expenses increased $.8 million (10%) for the quarter ended March
31, 1999, as compared to the same period last year, primarily due to an increase
in administrative and general activities.

Depreciation

Depreciation  increased  $.3 million (10%) for the quarter ended March 31, 1999,
as compared to the same period last year, due to additions to depreciable plant.

Other Income and (Expenses) - Net

The change in other  income and  (expenses) - net of $.1 million for the quarter
ended March 31,  1999,  as compared  to the same  period of 1998,  is  primarily
attributable to an increase in miscellaneous non-utility revenues.

Interest

The  increase in interest  expense of $.4  million  (40%) for the quarter  ended
March 31, 1999,  as compared to the same period last year,  was primarily due to
the net  issuance  of  approximately  $30 million of  long-term  debt during the
period of April 1998 through December 1998.

Cinergy, CG&E, and PSI

4.   Cinergy'senergy  marketing  and  trading  operations,  conducted  primarily
     through its ECBU,  markets and trades  electricity,  natural gas, and other
     energy-related products. The power marketing and trading operation has both
     physical  and trading  activities.  Generation  not required to meet native
     load  requirements  is available to be sold to third parties,  either under
     long-term contracts, such as full requirements transactions or firm forward
     sales  contracts,  or in  short-term  and spot  market  transactions.  When
     transactions  are entered into, each  transaction is designated as either a
     physical  or  trading  transaction.  In  order  for  a  transaction  to  be
     designated  as  physical,  there must be intent and  ability to  physically
     deliver the power from company-owned generation.  Physical transactions are
     accounted for on a settlement basis. All other  transactions are considered
     trading transactions and are accounted for using the mark-to-market  method
     of accounting. Under the mark-to-market method of accounting, these trading
     transactions are reflected at fair value as "Energy risk management assets"
     and "Energy risk management  liabilities." Changes in fair value, resulting
     in  unrealized  gains and losses,  are reflected in "Fuel and purchased and
     exchanged  power."  Revenues  and costs for all  transactions  are recorded
     gross in

<PAGE>





     the  Consolidated  Statements of Income as contracts are settled.  Revenues
     are recognized in "Operating Revenues - Electric" and costs are recorded in
     "Fuel and purchased and exchanged power."

     Although  physical  transactions are entered with the intent and ability to
     settle the contract with company-owned  generation, it is likely, that from
     time to time, due to numerous  factors such as generating  station outages,
     native load  requirements,  and weather,  power used to settle the physical
     transactions will be required to be purchased on the open market. Depending
     on the factors giving rise to these open market purchases, the cost of such
     purchases  could be in excess of the  associated  revenues.  Losses such as
     this will be recognized as the power is  delivered.  In addition,  physical
     contracts  are subject to permanent  impairment  tests.  At March 31, 1999,
     management has concluded that no physical contracts are impaired.

     Prior to December 31, 1998,  the  transactions  now included in the trading
     portfolio were  accounted for and valued at the aggregate  lower of cost or
     market.  Under this method,  only the net value of the entire portfolio was
     recorded as a liability in the Consolidated Balance Sheets.

     Contracts  in the  trading  portfolio  are valued at  end-of-period  market
     prices,  utilizing  factors  such as closing  exchange  prices,  broker and
     over-the-counter  quotations,  and model pricing.  Model pricing  considers
     time value and volatility  factors  underlying any options and  contractual
     commitments. Management expects that some of these obligations, even though
     considered as trading  contracts,  will  ultimately be settled from time to
     time by using  company-owned  generation.  The cost of this  generation  is
     typically  below the market prices at which the trading  portfolio has been
     valued.

     Because of the volatility  currently  experienced in the power markets, and
     the factors  discussed  above  pertaining  to both the physical and trading
     activities, volatility in future earnings (losses) from period to period in
     the ECBU is likely.

     Cinergy's ECBU also  physically  markets natural gas and trades natural gas
     and other  energy-related  products.  All of these operations are accounted
     for on the  mark-to-market  method of  accounting.  Revenues and costs from
     physical  marketing are recorded  gross in the  Consolidated  Statements of
     Income as  contracts  are  settled  due to the  exchanging  of title to the
     natural gas throughout the earnings process. All non-physical  transactions
     are  recorded net in the  Consolidated  Statements  of Income.  Energy risk
     management  assets and  liabilities  and gross  margins from these  trading
     activities currently are not significant.

5.   Cinergy and its subsidiaries use derivative financial  instruments to hedge
     exposures to foreign  currency  exchange  rates,  lower funding costs,  and
     manage  exposures to fluctuations in interest  rates.  Instruments  used as
     hedges must be  designated  as a hedge at the inception of the contract and
     must be effective at reducing the risk  associated  with the exposure being
     hedged.   Accordingly,   changes  in  market  values  of  designated  hedge
     instruments must be highly  correlated with changes in market values of the
     underlying  hedged items at inception of the hedge and over the life of the
     hedge contract.

     Cinergy and its subsidiaries utilize foreign exchange forward contracts and
     currency  swaps  to  hedge  certain  of  its  net  investments  in  foreign
     operations.  Accordingly,  any  translation  gains or losses related to the
     foreign  exchange  forward  contracts  or  the  principal  exchange  on the
     currency swap are recorded in "Accumulated other comprehensive loss," which
     is a separate  component  of common  stock  equity.  Aggregate  translation
     losses related to these instruments are reflected in "Current  Liabilities"
     in the Consolidated Balance Sheets.

     Interest  rate  swaps  are   accounted   for  under  the  accrual   method.
     Accordingly,  gains and losses based on any interest  differential  between
     fixed-rate and floating-rate  interest  amounts,  calculated on agreed upon
     notional principal amounts,  are recognized in the Consolidated  Statements
     of Income as a component of interest  expense as realized  over the life of
     the agreement.

6.   As discussed in the 1998 Form 10-K, prior to the 1950s, gas was produced at
     MGP sites  through a process that  involved the heating of coal and/or oil.
     The gas produced  from this process was sold for  residential,  commercial,
     and industrial uses.

Cinergy and PSI

     Coal tar residues, related hydrocarbons, and various metals associated with
     MGP sites  have been  found at former MGP sites in  Indiana,  including  at
     least 21 MGP sites  which PSI or its  predecessors  previously  owned.  PSI
     acquired four of the sites from NIPSCO in 1931 and at the same time it sold
     NIPSCO the sites located in Goshen and Warsaw,  Indiana.  In 1945, PSI sold
     19 of these sites  (including  the four it acquired from NIPSCO) to Indiana
     Gas and Water  Company,  Inc.  (now IGC).  One of the 19 sites,  located in
     Rochester, Indiana, was later sold by IGC to NIPSCO.

     IGC and NIPSCO  both made  claims  against  PSI,  contending  that PSI is a
     Potentially  Responsible  Party under the CERCLA with respect to the 21 MGP
     sites, and therefore legally responsible for the costs of investigating and
     remediating  these  sites.  Moreover,  in August  1997,  NIPSCO  filed suit
     against PSI in federal court, claiming,  pursuant to CERCLA,  recovery from
     PSI of NIPSCO's past and future costs of investigating  and remediating MGP
     related contamination at the Goshen MGP site.

     In November 1998,  NIPSCO,  IGC, and PSI entered into a Site  Participation
     and Cost  Sharing  Agreement  by which they  settled  allocation  of CERCLA
     liability for past and future costs,  among the three  companies,  at seven
     MGP sites in Indiana. Pursuant to this agreement,  NIPSCO's lawsuit against
     PSI was  dismissed.  The parties  have  assigned  one of the  parties  lead
     responsibility   for  managing   further   investigation   and  remediation
     activities at each of the sites.  Similar  agreements  were reached between
     IGC and PSI which  allocate  CERCLA  liability  at 14 MGP sites  with which
     NIPSCO had no involvement. These agreements conclude all CERCLA and similar
     claims between the three companies  relative to MGP sites.  Pursuant to the
     agreements and  applicable  laws, the parties are continuing to investigate
     and remediate the sites as appropriate.  Investigation  and cleanup of some
     of the sites is subject to oversight by the IDEM.

     PSI has placed its insurance carriers on notice of IGC's, NIPSCO's, and the
     IDEM's  claims  related  to MGP  sites.  In April  1998,  PSI filed suit in
     Hendricks  County  Circuit  Court against its general  liability  insurance
     carriers  seeking,  among other  matters,  a declaratory  judgment that its
     insurance  carriers are  obligated to defend MGP claims  against PSI or pay
     PSI's costs of defense and to indemnify PSI for its costs of investigating,
     preventing, mitigating, and remediating damage to

<PAGE>





     property and paying claims  associated  with MGP sites.  PSI cannot predict
     the outcome of this litigation.

     Based upon the work  performed to date, PSI has accrued costs for the sites
     related  to  investigation,   remediation,   and  groundwater   monitoring.
     Estimated costs of certain remedial  activities are accrued when such costs
     are reasonably  estimable.  PSI does not believe it can provide an estimate
     of the reasonably  possible total  remediation  costs for any site prior to
     completion   of  a   remedial   investigation/feasibility   study  and  the
     development  of some  sense of the  timing  for the  implementation  of the
     potential  remedial  alternatives,  to the extent such  remediation  may be
     required.  Accordingly,  the total costs that may be incurred in connection
     with the remediation of all sites, to the extent  remediation is necessary,
     cannot be determined at this time. These future costs at the 21 Indiana MGP
     sites,  based on  information  currently  available,  are not  material  to
     Cinergy's financial condition or results of operations. However, as further
     investigation and remediation activities are undertaken at these sites, the
     potential liability for the 21 MGP sites could be material to Cinergy's and
     PSI's financial condition or results of operations.

Cinergy, CG&E, and ULH&P

     CG&E and its utility  subsidiaries  are aware of potential  sites where MGP
     activities  have occurred at some time in the past.  None of these sites is
     known  to  present  a  risk  to  the  environment.  CG&E  and  its  utility
     subsidiaries  have undertaken  preliminary  site assessments to obtain more
     information about some of these MGP sites.

7.   During the second quarter of 1998,  the FASB issued  Statement 133. The new
     standard requires companies to record derivative instruments, as defined in
     Statement  133,  as assets or  liabilities,  measured  at fair  value.  The
     Statement   requires  that  changes  in  the  derivative's  fair  value  be
     recognized  currently in earnings unless specific hedge accounting criteria
     are met.  Special  accounting for  qualifying  hedges allows a derivative's
     gains and losses to offset related results on the hedged item in the income
     statement,  and requires that a company must formally document,  designate,
     and assess the  effectiveness of transactions that receive hedge accounting
     treatment.  The standard is effective for fiscal years beginning after June
     15, 1999,  and Cinergy  expects to adopt the provisions of Statement 133 in
     the first quarter of 2000.

The  Company has not yet quantified the impacts of adopting Statement 133 on its
     consolidated  financial statements.  However,  Statement 133 could increase
     volatility in earnings and other comprehensive income.

9.   Midlands (of which the Company owns 50%) has a 40% ownership  interest in a
     586 MW  power  project  in  Pakistan  ("Uch  project"  or  "Uch")  which as
     originally  scheduled to begin  commercial  operation in late 1998. In July
     1998, the Pakistani  government-owned  utility issued a notice of intent to
     terminate certain key project agreements  relative to the Uch project.  The
     notice  asserted  that various  forms of  corruption  were  involved in the
     original  granting of the  agreements to the Uch investors by a predecessor
     government.  The  Company  believes  that this notice is similar to notices
     received by a number of other independent power projects in Pakistan.

     The Uch  investors,  including a subsidiary of Midlands,  strongly deny the
     allegations  and have pursued all available  legal options to enforce their
     contractual rights under the project agreements.  Physical  construction of
     the project is complete;  however,  commercial operations have been delayed
     pending  resolution  of  the  dispute.  In  December  1998,  the  Pakistani
     government offered to withdraw its notice.

Through its 50% ownership of Midlands,  the Company's current  investment in the
Uch project is  approximately  $36 million.  In addition,  project lenders could
require investors to make additional capital  contributions to the project under
certain  conditions.  The Company's share of these  additional  contributions is
approximately  $8 million.  At the present time,  the Company cannot predict the
ultimate outcome of this matter.

Cinergy and PSI

10.  As  discussed  in the 1998 Form  10-K,  PSI and  Dynegy  (formerly  Destec)
     entered  into a 25-year  contractual  agreement  for the  provision of coal
     gasification  services in November 1995. The agreement  requires PSI to pay
     Dynegy a base monthly fee including certain monthly operating expenses. PSI
     received  authorization  in the  September  1996 Order for the inclusion of
     these costs in retail rates.  In addition,  PSI received  authorization  to
     defer,  for subsequent  recovery in retail rates, the base monthly fees and
     expenses  incurred prior to the effective date of the September 1996 Order.
     Over the next five years,  the base  monthly fees and expenses for the coal
     gasification service agreement are expected to total $201 million.

     During the third quarter of 1998,  PSI reached an agreement  with Dynegy to
     purchase  the  remainder  of its  25-year  contract  for coal  gasification
     services for $265.7  million.  The proposed  purchase,  which is contingent
     upon regulatory  approval  satisfactory to PSI, could be completed in 1999.
     PSI is investigating financing alternatives.  The transaction,  if approved
     as proposed, is not expected to have a material impact on PSI's earnings.

     Currently,  natural  gas prices  have  fallen to a level  which  causes the
     synthetic  gas  supply  taken  under  the  current  gasification   services
     agreement  to  be  substantially   above  market.  If  the  buyout  of  the
     gasification services agreement is approved, the combustion turbine will be
     fired with  natural gas, or with  synthetic  gas if it can be produced at a
     cost competitive with natural gas.

11.  As discussed  in the 1998 Form 10-K,  the  collective-bargaining  agreement
     with the  International  Brotherhood of Electrical  Workers Local No. 1393,
     covering approximately 1,470 employees, expired on May 1, 1999. A new labor
     agreement was ratified  April 22, 1999,  and is effective from May 1, 1999,
     through April 30, 2002.

Cinergy, CG&E, PSI, and ULH&P

12.  As  discussed  in  the  1998  Form  10-K,  during  1998,  Cinergy  and  its
     subsidiaries  adopted the  provisions  of Statement  131.  During the first
     quarter of 1999, Cinergy reorganized its reportable segments.  The business
     unit structure effective with that reorganization is described below.

     The ECBU operates and maintains,  exclusive of certain jointly-owned plant,
     all of the Company's domestic electric generation  facilities.  In addition
     to the production of electric power, all energy risk management, marketing,
     and proprietary  arbitrage trading,  with the exception of electric and gas
     retail  sales,  is  conducted  through  the ECBU.  Revenues  from  external
     customers  are  derived  from  the  ECBU's  marketing,  trading,  and  risk
     management  activities.  Intersegment revenues are derived from the sale of
     electric power to the EDBU.

     The  EDBU  plans,   constructs,   operates,  and  maintains  the  Company's
     transmission and distribution  systems and provides gas and electric energy
     to end users.  Revenues from  customers  other than end users are primarily
     derived  from the  transmission  of electric  power  through the  Company's
     transmission system.

     The CIBU  manages  the  development,  sales,  and  marketing  of  domestic,
     non-regulated  wholesale energy and  energy-related  products and services.
     Most of the CIBU's revenues are derived from the sales of such products and
     services to external,  end-use customers.  In addition,  some of the CIBU's
     activities are conducted through  joint-venture  affiliates,  including the
     construction and sale or lease of cogeneration and trigeneration facilities
     to large commercial/industrial  customers and energy management services to
     third parties.

     The IBU directs and manages  all of the  Company's  international  business
     holdings,  which include wholly-owned  subsidiaries and equity investments.
     Revenues and equity  earnings from  unconsolidated  companies are primarily
     derived from energy-related businesses.

     Transfer pricing for sales of electric energy and sales of electric and gas
     transmission  and  distribution  services  between  the  ECBU  and EDBU are
     derived from the operating utilities' retail and wholesale rate structures.

            ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS

Cinergy,  CG&E, PSI, and ULH&P 
CAUTIONARY STATEMENTS REGARDING FORWARD-LOOKING INFORMATION Matters discussed in
this "Item 2.  Management's  Discussion and Analysis of Financial  Condition and
Results of Operations" in "Part I. Financial  Information" reflect and elucidate
Cinergy's  corporate vision of the future and, as a part of that,  outline goals
and aspirations,  as well as specific  projections.  These goals and projections
are considered forward-looking statements and are based on management's beliefs,
as well as certain  assumptions made by management.  Forward-looking  statements
involve  risks  and  uncertainties  which  may cause  actual  results  to differ
materially from the forward-looking  statements.  In addition to any assumptions
and other factors that are referred to  specifically  in  connection  with these
statements,  other factors that could cause actual results to differ  materially
from those indicated in any forward-looking  statements  include,  among others:
factors  generally  affecting  operations,  such as unusual weather  conditions,
unscheduled  generation outages;  unusual maintenance or repairs,  unanticipated
changes  in  fuel  costs,   environmental   incidents,  or  system  constraints;
legislative and regulatory  initiatives regarding deregulation and restructuring
of  the  industry;  increased  competition  in  the  electric  and  gas  utility
environment;  challenges  related to Year 2000  readiness;  regulatory  factors;
changes in  accounting  principles or policies;  adverse  political,  legal,  or
economic conditions; changing market conditions; success of efforts to invest in
and develop new opportunities in non-traditional business;  availability or cost
of capital;  employee workforce  factors;  legal and regulatory delays and other
obstacles  associated  with  mergers,  acquisitions,  and  investments  in joint
ventures; costs and effects of legal and administrative proceedings;  changes in
legislative  requirements;  and  other  risks.  The SEC's  rules do not  require
forward-looking statements to be revised or updated, and Cinergy does not intend
to do so.

FINANCIAL CONDITION

Recent Developments

Cinergy
Acquisitions   During  the  first   quarter  of  1999,   Cinergy,   through  its
international subsidiaries,  invested an additional $41 million in international
unconsolidated subsidiaries.

Competitive Pressures

Cinergy, CG&E, PSI, and ULH&P
Ohio As discussed in the 1998 Form 10-K, electric restructuring  legislation was
reintroduced  in  1999  in both  houses  of the  Ohio  General  Assembly.  These
companion  bills  propose to give  choice to all retail  electric  customers  by
January 1, 2001. As written,  the legislation has not gained consensus among the
stakeholders.

The Ohio Senate Ways and Means  Committee has scheduled a vote on a deregulation
bill during the second  quarter of 1999 with a full senate vote  scheduled  if a
bill is reported  from  committee.  It is uncertain  whether  these efforts will
produce legislation in Ohio in 1999.



<PAGE>






Indiana As  discussed  in the 1998 Form 10-K,  legislation  by a large  group of
industrial  customers was  introduced  into the Indiana  legislature  in January
1999.  This  legislation did not pass in the 1999 session of the Indiana General
Assembly, which came to a close on April 29, 1999.

Environmental Issues

Cinergy, CG&E, and PSI
Ozone Transport  Rulemaking As discussed in the 1998 Form 10-K, in October 1998,
the EPA finalized its Ozone  Transport Rule (or NOx SIP Call).  It applies to 22
states in the eastern  half of the US,  including  the three states in which the
Cinergy  electric  utilities  operate,  and also  proposes  a model NOx  trading
program.  This rule  recommends  that states reduce NOx emissions from primarily
industrial and utility  sources to a certain limit by May 2003. The EPA gave the
affected states until September 30, 1999, to incorporate  utility NOx reductions
with a trading program into their SIPs. Ohio, Indiana, a number of other states,
and various industry groups,  including some of which Cinergy is a member, filed
legal  challenges  to the NOx SIP Call in late 1998.  Ohio and Indiana have also
provided  preliminary  indications that they will seek fewer NOx reductions from
the utility sector in their  implementing  regulations than the EPA has budgeted
in its rulemaking.

On April 30, 1999, the EPA made an affirmative  technical  determination  on the
February 1998 northeast state CAAA Section 126 petitions seeking to reduce ozone
in the eastern US. By  affirming  these  Section 126  petitions  the EPA makes a
finding that the named Midwest  stationary  sources  (including all of Cinergy's
facilities)  are  significantly  contributing to ozone problems in the northeast
for both the one- and  eight-hour  ozone  standard.  The EPA has stated that the
Section 126 petitions and the NOx SIP call  requirements  should be coordinated.
Therefore,  the EPA will defer fully  granting the relief sought by  petitioners
until the affected states file their proposed SIPs in September 1999.

Ambient Air  Standards  and Regional Haze As discussed in the 1998 Form 10-K, in
1997, the EPA revised the National  Ambient Air Quality  Standards for ozone and
fine particulate matter and was scheduled to finalize new regional haze rules by
the summer of 1999. It is currently anticipated that the new ozone standard will
not require  additional  utility NOx reductions  beyond those resulting from the
NOx SIP Call discussed above.

The EPA  finalized  the new regional  haze rules on April 22, 1999.  These rules
established  planning  and  emission  reduction  timelines  for states to use to
improve  visibility in national parks  throughout the US. The ultimate effect of
the new  regional  haze  rules  could be  requirements  for  newer  and  cleaner
technologies  and  additional  controls  on  conventional   particulates  and/or
reductions  in SO2 and NOx  emissions  from  utility  sources.  If more  utility
emissions reductions are required, the compliance cost could be significant. The
outcome or effects of the states' determination cannot currently be predicted.

Air  Toxics As  discussed  in the 1998 Form  10-K,  in  November  1998,  the EPA
finalized  its Mercury  ICR.  Pursuant  to the ICR,  all  generating  units must
provide detailed  information  about coal use and mercury  content.  The EPA has
since selected about 100 generating units for one-time stack sampling, including
Cinergy's Gibson Unit No. 3 and the Wabash River Repowering Project.  The EPA is
planning  to make  its  regulatory  determination  on the  need  for  additional
regulation  by the fourth  quarter of 2000. If more air toxics  regulations  are
issued, the compliance cost could be significant.  The outcome or effects of the
EPA's determination cannot currently be predicted.

Market Risk Sensitive Instruments and Positions

Cinergy, CG&E, and PSI
Energy  Commodities  Sensitivity  The Company  markets  and trades  electricity,
natural  gas,  and  other   energy-related   products.   The  Company   utilizes
over-the-counter  forward  and option  contracts  for the  purchase  and sale of
electricity and also trades exchange-traded futures contracts. See Notes 4 and 5
of the "Notes to Financial  Statements" in "Part I. Financial  Information"  for
the  Company's  accounting  policies  for certain  derivative  instruments.  The
Company's  market  risks  have not  changed  materially  from the  market  risks
reported in the 1998 Form 10-K.

Cinergy
Exchange  Rate   Sensitivity  The  Company  utilizes  foreign  exchange  forward
contracts and currency swaps to hedge certain of its net  investments in foreign
operations. See Notes 4 and 5 of the "Notes to Financial Statements" in "Part I.
Financial  Information"  for  the  Company's  accounting  policies  for  certain
derivative  instruments.  The Company's market risks have not changed materially
from the market risks reported in the 1998 Form 10-K.

Cinergy, CG&E, PSI, and ULH&P
Interest  Rate  Sensitivity  The  Company's  net exposure to changes in interest
rates primarily  consists of debt instruments with floating  interest rates that
are benchmarked to various market indices.  To manage the Company's  exposure to
fluctuations  in  interest  rates  and  to  lower  funding  costs,  the  Company
constantly  evaluates the use of, and has entered into, interest rate swaps. See
Notes 4 and 5 of the  "Notes  to  Financial  Statements"  in "Part I.  Financial
Information"  for the  Company's  accounting  policies  for  certain  derivative
instruments.  The Company's  market risks have not changed  materially  from the
market risks reported in the 1998 Form 10-K.

Cinergy, CG&E, and PSI
Cinergy's  committed lines are comprised of an acquisition  line and a revolving
line. The established  revolving line also provides credit support for Cinergy's
commercial paper program, which is limited to a maximum principal amount of $400
million.  The  proceeds  from the  commercial  paper sales were used for general
corporate purposes.

The  established  committed  lines  for CG&E and PSI each  include  $75  million
designated  as backup for certain of the  uncommitted  lines at March 31,  1999.
CG&E and PSI also  have the  capacity  to issue  commercial  paper  that must be
supported by committed  lines of the  respective  company.  Neither CG&E nor PSI
issued commercial paper during the first quarter of 1999.

Both CG&E and PSI have issued variable rate pollution control notes.  Holders of
these pollution  control notes have the right to put their notes on any business
day.  Accordingly,  these  issuances are reflected in the  Consolidated  Balance
Sheets as "Notes payable and other short-term obligations."

Cinergy
Global Resources  established a $100 million revolving credit agreement in 1998,
which was due to expire in March 1999 and has been extended to June 29, 1999.

Cinergy, CG&E, PSI, and ULH&P
Year 2000 The Year 2000 issue generally exists because many computer systems and
applications,   including  those  embedded  in  equipment  and  facilities,  use
two-digit rather than four-digit date fields to designate an applicable year. As
a  result,  the  systems  and  applications  may not  properly  recognize  dates
including  and beyond  the year 2000 or  accurately  process  data in which such
dates are included, potentially causing data miscalculations and inaccuracies or
operational   malfunctions  and  failures,   which  could  materially  affect  a
business's financial condition, results of operations, and cash flows.

Cinergy has established a centrally-managed,  company-wide initiative,  known as
the Cinergy Year 2000 Readiness Program, to identify, evaluate, and address Year
2000 issues. The Cinergy Year 2000 Readiness Program,  which began in the fourth
quarter of 1996,  is generally  focused on three  elements  that are integral to
this  initiative:   (1)  business  continuity,  (2)  risk  management,  and  (3)
regulatory compliance.  Business continuity includes providing reliable electric
and gas supply and service in a safe and  cost-effective  manner.  This  element
encompasses mission-critical generation,  transmission, and distribution systems
and related infrastructure,  as well as operational and financial IT systems and
applications,  end-user  computing  resources,  and  building  systems  (such as
security, elevator, and heating and cooling systems). Risk management includes a
review of the Year 2000 readiness efforts of Cinergy's critical  suppliers,  key
customers  and other  principal  business  partners,  and, as  appropriate,  the
development of joint business support,  contingency  plans, and the inclusion of
Year 2000  concerns as a regular  part of the due  diligence  process in any new
business venture.  Regulatory compliance includes communications with regulatory
agencies, other utilities, and various industry groups. While this initiative is
broad in scope,  it has been  structured to identify and prioritize  efforts for
mission-critical  electric  and  gas  systems  and  services  and  key  business
partners.

Under the Cinergy Year 2000 Readiness Program,  Cinergy has established a target
date of June 30, 1999, for the remediation  and testing of its  mission-critical
generation,  transmission,  and  distribution  systems  (gas and  electric).  An
innovative  remediation and testing effort which Cinergy has initiated  involves
operating several electric-generating units with post Year 2000 dates. Cinergy's
experience  has been that those  units have  continued  to operate  without  any
material  adverse result  relating to a Year 2000 issue.  Cinergy's  progress to
date ranges from  approximately  95% regarding IT systems to  approximately  87%
regarding assessment of critical suppliers.

Cinergy has also reviewed its existing contingency and business continuity plans
and  modified  them in light of the Year 2000  issue.  Contingency  planning  to
maintain  and  restore  service  in the event of  natural  and  other  disasters
(including software- and  hardware-related  problems) has been part of Cinergy's
standard  operation  for many years,  and  Cinergy is working to  leverage  this
experience  in the  review  of  existing  plans  to  address  Year  2000-related
challenges. These reviews have assessed the potential for business disruption in
various scenarios, including the most reasonably likely worst-case scenario, and
to provide for key operational back up, recovery, and restoration alternatives.

Cinergy  cannot  guarantee  that third  parties on whom it depends for essential
goods and services (those where the interruption of the supply of such goods and
services could lead to issues involving the safety of employees,  customers,  or
the public; the continued reliable delivery of gas and/or  electricity;  and the
ability to comply  with  applicable  laws or  regulations)  will  convert  their
mission-critical  systems and processes in a timely manner.  Failure or delay by
any of these third parties could  significantly  disrupt business.  However,  to
address this issue,  Cinergy has established a supplier compliance program,  and
is working with its critical suppliers in an effort to minimize such risks.

In addition,  Cinergy is  coordinating  its findings and other issues with other
utilities and various industry groups via the Electric Power Research  Institute
Year  2000  Embedded  Systems  Project  and the Year 2000  Readiness  Assessment
Program of the NERC, acting at the request of the DOE. The DOE has asked NERC to
report on the  integrity  of the  transmission  system for North  America and to
coordinate and assess the  preparation of the electric  systems in North America
for the Year 2000.  NERC  submitted  its  initial  quarterly  status  report and
coordination  plan to the DOE in September 1998, and a second  quarterly  status
report for the fourth quarter of 1998 was submitted on January 11, 1999. A third
quarterly status report for the first quarter of 1999 was submitted on April 30,
1999.

Cinergy currently  estimates that the total cost for the inventory,  assessment,
remediation,  testing, and upgrading of its systems as a result of the Year 2000
effort is approximately $13 million.  Approximately $12 million in expenses have
been incurred  through March 31, 1999,  for such things as external  labor,  for
hardware and software  upgrades,  and for Cinergy  employees  who are  dedicated
full-time  to the  Cinergy  Year 2000  Readiness  Program.  The  timing of these
expenses may vary and is not  necessarily  indicative  of  readiness  efforts or
progress to date.  Cinergy  anticipates that a portion of its Year 2000 expenses
will not be incremental  costs,  but rather,  will represent the redeployment of
existing IT  resources.  Since its  formation,  Cinergy has  incurred,  and will
continue to incur,  significant  capital  improvement  costs  related to planned
system upgrades or replacements required in the normal course of business. These
costs have not been accelerated as a result of the Year 2000 issue.

The above information is based on Cinergy's  current best estimates,  which were
derived using numerous assumptions of future events,  including the availability
and  future  costs of certain  technological  and other  resources,  third-party
modification  actions,  and other factors.  Given the complexity of these issues
and possible  unidentified  risks, actual results may vary materially from those
anticipated  and  discussed  above.  Specific  factors  that  might  cause  such
differences  include,  among  others,  the  ability  to locate and  correct  all
affected   computer  code,  the  timing  and  success  of  remedial  efforts  of
third-party suppliers, and similar uncertainties.

The  above  information  is a Year 2000  Readiness  Disclosure  pursuant  to the
Federal Year 2000 Information and Readiness Disclosure Act.

Cinergy
Other  Commitments  At March 31,  1999,  Cinergy  had  issued  $297  million  in
guarantees  primarily related to the energy marketing and trading  activities of
its  subsidiaries  and  affiliates.  In addition,  Cinergy had  guaranteed  $258
million of the debt securities of its subsidiaries and affiliates.

         this Section,  the registered  owner of all of the Bonds of Series BBB,
         CCC, and DDD initially shall be The Depository Trust Company ("DTC") or
         its nominee, and such Bonds of Series BBB, CCC, and DDD initially shall
         be  registered  in the  name  of DTC or  its  nominee.  Payment  of the
         principal  of or  interest  on  Bonds  of  Series  BBB,  CCC,  and  DDD
         registered  in the  name  of DTC or its  nominee  shall  be made in the
         manner   and  at  the   address(es)   specified   in  the   Letter   of
         Representations, dated April 30, 1999, from the Company and the Trustee

         their) participating institutions  (collectively  "Participants") shall
         maintain a book-entry  registration and transfer system with respect to
         ownership of beneficial  interests in the Bonds of Series BBB, CCC, and
         DDD (the "Book-Entry System").

              (b) The Bonds of Series  BBB,  CCC,  and DDD,  initially  shall be
         issued  in  the  form  of  a  separate,  single,  authenticated,  fully
         registered  bond for each such series (each a "Global  Debt  Security")
         which  (i)  need  not be in the  form  of a  lithographed  or  engraved
         certificate,  but may be  typewritten  or printed on ordinary  paper or
         such paper as the Trustee may reasonably request,  (ii) shall represent
         and be  denominated  in an  amount  equal  to  100%  of  the  aggregate
         principal  amount  of  the  Bonds  of  Series  BBB,  CCC,  or  DDD  (as
         applicable)  issued under this Supplemental  Indenture,  (iii) shall be
         executed by the Company and  authenticated by the Trustee in accordance
         with the provisions of the  Indenture,  (iv) shall be registered in the
         name of DTC or its  nominee,  and  delivered to DTC or its nominee or a
         custodian  therefor,  and (v) shall contain the following legend on the
         face thereof:

                       Unless this  certificate  is presented  by an  authorized
                       representative  of The Depository  Trust  Company,  a New
                       York  corporation  ("DTC"),  to  issuer  or its agent for
                       registration  of transfer,  exchange or payment,  and any
                       certificate issued is registered in the name of Cede & Co
                       or in such other name as is  requested  by an  authorized
                       representative  of DTC (and any payment is made to Cede &
                       Co.  or  to  such  other  entity  as is  requested  by an
                       authorized  representative of DTC), ANY TRANSFER,  PLEDGE
                       OR OTHER USE HEREOF FOR VALUE OR  OTHERWISE  BY OR TO ANY
                       PERSON IS  WRONGFUL  inasmuch  as the  registered  holder
                       hereof, Cede & Co., has an interest herein.

         Unless  and  until it is  exchanged  in  whole or in part for  Bonds of
Series BBB,  CCC, or DDD (as  applicable)  in  definitive  certificated  form, a
Global Debt Security  representing  the Bonds of a particular  Series may not be
transferred  except as a whole by DTC to a nominee of DTC or by a nominee of DTC
to DTC or another  nominee of DTC or by DTC or any such  nominee to a  successor
securities depository or a nominee of any such successor securities depository.

                  (c) The  Trustee  and the  Company may treat Cede & Co. or its
         nominee,  or any successor  securities  depository  or nominee  thereof
         (collectively, the "Depository") as the sole and exclusive owner of the
         Bonds of  Series  BBB,  CCC,  and DDD,  registered  in its name for the
         purposes of payment of the principal or redemption price of or interest
         on the Bonds of Series  BBB,  CCC, or DDD (as  applicable),  giving any
         notice  permitted  or  required  to be given to holders of the Bonds of
         Series BBB,  CCC, or DDD (as  applicable),  under the Indenture or this
         Supplemental Indenture, registering the transfer of the Bonds of Series
         BBB, CCC, and DDD, obtaining any consent or other action to be taken by
         holders of the Bonds of Series BBB,  CCC, or DDD (as  applicable),  and
         for all other  purposes  whatsoever  and  neither  the  Trustee nor the
         Company  shall be affected by any notice to the  contrary.  Neither the
         Company nor the Trustee nor any  registrar  nor any paying  agent shall
         have any  responsibility  or obligation to any Participant,  any person
         claiming a  beneficial  ownership  interest in the Bonds of Series BBB,
         CCC,  or DDD (as  applicable)  under or through the  Depository  or any
         Participant, or any other person which is not shown on the registration
         books as being a holder  of the Bonds of Series  BBB,  CCC,  or DDD (as
         applicable) with respect to (i) the accuracy of any records  maintained
         by  the  Depository  or  any  Participant;  (ii)  the  payment  by  the
         Depository to any Participant of any amount in respect of the principal
         or redemption  price of or interest on the Bonds of Series BBB, CCC, or
         DDD (as applicable);  (iii) the payment by any Participant to any owner
         of a beneficial  ownership interest in the Bonds of Series BBB, CCC, or
         DDD (as applicable),  in respect of the principal of or interest on the
         Bonds of Series BBB, CCC, or DDD (as applicable) or (iv) any consent or
         other  action taken by the  Depository  as owner of the Bonds of Series
         BBB, CCC, or DDD (as  applicable).  The Trustee shall pay all principal
         of  and  interest  on  the  Bonds  of  Series  BBB,  CCC,  or  DDD  (as
         applicable),  only to or upon the  order of the  registered  holder  or
         holders of the Bonds of Series  BBB,  CCC, or DDD (as  applicable),  as
         shown on the  registration  books, and all such payments shall be valid
         and effective to fully satisfy and discharge the Company's  obligations
         with respect to the  principal or  redemption  price of and interest on
         the Bonds of Series BBB, CCC, or DDD (as applicable),  to the extent of
         the sum or sums so paid.  No person other than a holder of the Bonds of
         Series BBB, CCC, or DDD (as  applicable),  as shown on the registration
         books of DTC,  shall  receive  an  authenticated  Bond  evidencing  the
         obligation  of the  Company  to make  payment of the  principal  of and
         interest  on the Bonds of Series  BBB,  CCC,  and DDD,  pursuant to the
         Indenture and this Supplemental Indenture.  Upon delivery by DTC to the
         Trustee of  written  notice to the effect  that DTC has  determined  to
         substitute  a new nominee for Cede & Co, and subject to the  provisions
         of the  Indenture  and this  Supplemental  Indenture,  the word "Cede &
         Co.", as used in this Supplemental  Indenture,  shall refer to each new
         nominee of DTC.

              (d) In the event that after the  occurrence of an event of default
         that has not been cured or waived,  holders of a majority in  aggregate
         principal  amount of the  beneficial  interests  in the Bonds of Series
         BBB,  the  Bonds  of  Series  CCC,  or the  Bonds  of  Series  DDD  (as
         applicable),  as reflected in the books and records of the  Depository,
         notify the Trustee, through the Depository or any Participant, that the
         continuation  of  the  Book-Entry  System  is no  longer  in  the  best
         interests of such holders of beneficial  interests in the Bonds of such
         Series,  then the Trustee shall notify the  Depository and the Company,
         and the Depository  will notify the  Participants  of the  availability
         through the Depository of definitive certificated Bonds of such Series.
         In such event, the Company shall execute, and the Trustee, upon receipt
         of a written  order of the Company,  signed by its  President or a Vice
         President  and by its  Treasurer,  Assistant  Treasurer,  Secretary  or
         Assistant  Secretary (an "Issue  Order"),  for the  authentication  and
         delivery  of  definitive  certificated  Bonds of Series  BBB,  Bonds of
         Series CCC, and Bonds Series DDD (as applicable), will authenticate and
         deliver  Bonds of such Series in definitive  certificated  form, in any
         authorized  denominations,  all  pursuant  to  the  provisions  of  the
         Indenture, to the person or persons specified to the Trustee in writing
         by the Depository in the aggregate  principal  amount of the applicable
         Global Debt Security or Securities and in exchange for such Global Debt
         Security or Securities.

              (e) If at any time the Depository  notifies the Company that it is
         unwilling or unable to continue as  Depository  for the Bonds of Series
         BBB,  the Bonds of Series CCC, or the Bonds of Series DDD, or if at any
         time the Depository  shall no longer be registered as a clearing agency
         in good standing under the Securities Exchange Act of 1934, as amended,
         or other  applicable  statute or regulation,  the Company may appoint a
         successor  Depository  with respect to the Bonds of such  Series.  If a
         successor  Depository  for the Bonds of such Series is not appointed by
         the Company  within 90 days after the Company  receives  such notice or
         becomes  aware of such  condition,  the Company will  execute,  and the
         Trustee,  upon  receipt of an Issuer Order for the  authentication  and
         delivery  of  definitive  certificated  Bonds of Series  BBB,  Bonds of
         Series CCC, and Bonds of Series DDD (as applicable),  will authenticate
         and deliver  Bonds of such Series in definitive  certificated  form, in
         any  authorized  denominations,  all pursuant to the  provisions of the
         Indenture, to the person or persons specified to the Trustee in writing
         by the Depository in the aggregate  principal  amount of the applicable
         Global Debt Security or Securities and in exchange for such Global Debt
         Security or Securities.

              (f)  The  Company  may at any  time  and  in its  sole  discretion
         determine that the Bonds of Series BBB, the Bonds of Series CCC, or the
         Bonds of Series  DDD shall no longer be  represented  by a Global  Debt
         Security. In such event the Company will execute, and the Trustee, upon
         receipt  of an Issuer  Order for the  authentication  and  delivery  of
         definitive  certificated  Bonds of such Series,  will  authenticate and
         deliver  Bonds of Series BBB,  Bonds of Series CCC, and Bonds of Series
         DDD (as applicable) in definitive  certificated form, in any authorized
         denominations,  all pursuant to the provisions of the Indenture, to the
         person or persons specified to the Trustee in writing by the Depository
         in the  aggregate  principal  amount  of  the  applicable  Global  Debt
         Security and in exchange for such Global Debt Security or Securities.

               (g) Upon the exchange of a Global Debt  Security for the Bonds of
          Series  BBB,  the Bonds of Series  CCC,  or the Bonds of Series DDD in
          definitive  certificated  form,  in  authorized   denominations,   the
          applicable  Global Debt Security or  Securities  shall be cancelled by
          the Trustee.

              (h) Whenever the  Depository  requests the Company and the Trustee
         to do  so,  the  Trustee  and  the  Company  will  cooperate  with  the
         Depository in taking  appropriate action after reasonable notice to (i)
         make available one or more separate Global Debt  Securities  evidencing
         the Bonds of Series  BBB,  the  Bonds of  Series  CCC,  or the Bonds of
         Series DDD to any  Participant  having Bonds of such Series credited to
         its account at the Depository,  or (ii) arrange for another  Depository
         to  maintain   custody  of  the  Global  Debt  Security  or  Securities
         evidencing  the Bonds of Series  BBB,  the Bonds of Series  CCC, or the

         This bond is one of the bonds of the  Company  issued  and to be issued
from time to time under and in  accordance  with and all secured by an indenture
of mortgage  or deed of trust,  dated  September  1, 1939,  from Public  Service
Company of Indiana  (predecessor  of the Company) to The First  National Bank of
Chicago, as Trustee, to which LaSalle National Bank is successor trustee, (which
indenture as amended by all supplemental  indentures is hereinafter  referred to
as the "Indenture").  Said Trustee or its successor in trust under the Indenture
is hereinafter  sometimes referred to as the "Trustee." Reference is hereby made
to the Indenture for a description of the property mortgaged and pledged and the
nature and extent of the security for said bonds. By the terms of the Indenture,
the bonds  secured  thereby are  issuable  in series  which may vary as to date,
amount,  date of  maturity,  rate of  interest  and in other  respects as in the
Indenture provided.

         This bond is one of a series  designated  as "PSI  Energy,  Inc.  First
Mortgage Bonds,  Series BBB, 8%, Due July 15, 2009" (hereinafter  referred to as
"Bonds of Series BBB") of the Company  issued under and secured by the Indenture
and  created by a  Fifty-Second  Supplemental  Indenture,  dated as of April 30,
1999, which also amends the Indenture.

         The  rights and  obligations  of the  Company  and of the  bearers  and
registered  owners of bonds may be modified  or amended  with the consent of the
Company by an affirmative  vote of the bearers or registered  owners entitled to
vote of at least  seventy-five per centum (75%) in principal amount of the bonds
then  outstanding at a meeting of bondholders  called for the purpose (and by an
affirmative  vote of the  bearers or  registered  owners  entitled to vote of at
least  seventy-five  per centum (75%) in principal amount of bonds of any series
affected by such  modification  or amendment in case one or more,  but less than
all,  series of bonds are so  affected),  all in the manner  and  subject to the
limitations set forth in the Indenture,  any consent by the bearer or registered
owner of any bond being  conclusive  and binding upon such bearer or  registered
owner  and  upon  all  future  bearers  or  registered   owners  of  such  bond,
irrespective  of whether  or not any  notation  of such  consent is made on such
bond; provided that no such modification or amendment shall, among other things,
extend the  maturity or reduce the amount of, or reduce the rate of interest on,
or otherwise modify the terms of the payment of the principal of, or interest or
premium (if any) on this bond, which obligations are absolute and unconditional,
or permit the  creation of any lien  ranking  prior to or equal with the lien of
the Indenture on any of the mortgaged property.

         The Bonds of Series BBB will be subject to redemption (the  "Make-Whole
Redemption")  at the option of the Company at any time in whole, or from time to
time in part,  until  maturity,  upon not  less  than 30 nor more  than 60 days'
notice,  at a redemption  price equal to the sum of (i) the principal  amount of
the Bonds of Series BBB being redeemed plus accrued and unpaid interest  thereon

any, with respect to such Bonds of Series BBB.

a Quotation  Agent (as defined  herein),  of the present values of the principal
amount of such Bonds of Series BBB, together with scheduled payments of interest
from the redemption  date to the stated  maturity of the Bonds of Series BBB, in
each case discounted to the redemption  date on a semi-annual  basis (assuming a
360-day year  consisting of twelve 30-day months) at the Adjusted  Treasury Rate
(as  defined  herein)  over  (ii) 100% of the  principal  amount of the Bonds of
Series BBB to be redeemed.

         "Adjusted Treasury Rate" means, with respect to any redemption date for
a Make-Whole Redemption,  the rate per annum equal to the semi-annual equivalent
yield  to  maturity  of the  Comparable  Treasury  Issue  (as  defined  herein),

percentage of its principal  amount) equal to the Comparable  Treasury Price (as
defined herein) for such redemption  date,  calculated on the third business day
preceding the redemption date, plus 0.15% (15 basis points).

         "Comparable  Treasury Issue" means the United States Treasury  security
selected by the Quotation Agent as having a maturity comparable to the remaining
term from the redemption  date to the stated maturity of the Bonds of Series BBB
that  would  be  utilized,  at the  time of  selection  and in  accordance  with
customary financial practice, in pricing new issues of corporate debt securities
of comparable maturity to the remaining term of the Bonds of Series BBB.

     "Quotation  Agent"  means the  Reference  Treasury  Dealer  selected by the
Trustee after consultation with the Company. "Reference Treasury Dealer" means a
primary U.S. Government securities dealer.

         "Comparable  Treasury Price" means, with respect to any redemption date

set forth in the daily statistical  release  designated "H.15" (or any successor
release)  published by the Board of Governors of the Federal  Reserve  System or
(ii) if such  release (or any  successor  release) is not  published or does not
contain  such prices on such  business  day,  (A) the  average of the  Reference
Treasury Dealer Quotations for such redemption date, after excluding the highest
and lowest such  Reference  Treasury  Dealer  Quotations,  or (B) if the Trustee
obtains fewer than three such Reference Treasury Dealer Quotations,  the average
of such Quotations.

         "Reference  Treasury  Dealer  Quotations"  means,  with respect to each
Reference  Treasury Dealer and any redemption date for a Make-Whole  Redemption,
the average, as determined by the Trustee (after consultation with the Company),
of the bid and asked prices for the Comparable Treasury Issue (expressed in each
case as a percentage of its principal  amount)  quoted in writing to the Trustee
by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third
business day preceding such redemption date.

         Notice of any redemption by the Company will be mailed at least 30 days
but not more than 60 days before any redemption  date to each holder of Bonds of
Series  BBB to be  redeemed.  If less than all the Bonds of Series BBB are to be
redeemed at the option of the Company,  the Trustee shall select, in such manner
as it shall deem fair and appropriate, the Bonds of Series BBB of such series to
be redeemed in whole or in part.

         Unless the Company defaults in payment of the redemption  price, on and
after any redemption date,  interest will cease to accrue on the Bonds of Series
BBB or portions thereof called for redemption.

         In the  case of any of  certain  events  of  default  specified  in the
Indenture,  the  principal  of this bond may be  declared  or may become due and
payable  prior to the stated date of maturity  hereof in the manner and with the
effect provided in the Indenture.

         No  recourse  shall  be had  for the  payment  of the  principal  of or
interest on this bond,  or for any claim based  hereon,  or otherwise in respect
hereof or of the Indenture, to or against any incorporator, shareholder, officer
or director,  past,  present or future,  of the Company or of any predecessor or
successor company, either directly or through the Company or such predecessor or
successor  company,  under any constitution or statute or rule of law, or by the
enforcement  of any assessment or penalty,  or otherwise,  all such liability of
incorporators, shareholders, directors and officers being waived and released by
the  registered  owner hereof by the  acceptance of this bond and being likewise
waived and released by the terms of the Indenture.

                      (FORM OF REVERSE OF SERIES DDD BOND)

         This bond is one of the bonds of the  Company  issued  and to be issued
from time to time under and in  accordance  with and all secured by an indenture
of mortgage  or deed of trust,  dated  September  1, 1939,  from Public  Service
Company of Indiana  (predecessor  of the Company) to The First  National Bank of
Chicago, as Trustee, to which LaSalle National Bank is successor trustee, (which
indenture as amended by all supplemental  indentures is hereinafter  referred to
as the "Indenture").  Said Trustee or its successor in trust under the Indenture
is hereinafter  sometimes referred to as the "Trustee." Reference is hereby made
to the Indenture for a description of the property mortgaged and pledged and the
nature and extent of the security for said bonds. By the terms of the Indenture,
the bonds  secured  thereby are  issuable  in series  which may vary as to date,
amount,  date of  maturity,  rate of  interest  and in other  respects as in the
Indenture provided.

         This bond is one of a series  designated  as "PSI  Energy,  Inc.  First
Mortgage Bonds, Series DDD, 8.31%, Due September 1, 2032" (hereinafter  referred
to as "Bonds of Series  DDD") of the  Company  issued  under and  secured by the
Indenture  and created by a  Fifty-Second  Supplemental  Indenture,  dated as of
April 30, 1999, which also amends the Indenture.

         The  rights and  obligations  of the  Company  and of the  bearers  and
registered  owners of bonds may be modified  or amended  with the consent of the
Company by an affirmative  vote of the bearers or registered  owners entitled to
vote of at least  seventy-five per centum (75%) in principal amount of the bonds
then  outstanding at a meeting of bondholders  called for the purpose (and by an
affirmative  vote of the  bearers or  registered  owners  entitled to vote of at
least  seventy-five  per centum (75%) in principal amount of bonds of any series
affected by such  modification  or amendment in case one or more,  but less than
all,  series of bonds are so  affected),  all in the manner  and  subject to the
limitations set forth in the Indenture,  any consent by the bearer or registered
owner of any bond being  conclusive  and binding upon such bearer or  registered
owner  and  upon  all  future  bearers  or  registered   owners  of  such  bond,
irrespective  of whether  or not any  notation  of such  consent is made on such
bond; provided that no such modification or amendment shall, among other things,
extend the  maturity or reduce the amount of, or reduce the rate of interest on,
or otherwise modify the terms of the payment of the principal of, or interest or
premium (if any) on this bond, which obligations are absolute and unconditional,
or permit the  creation of any lien  ranking  prior to or equal with the lien of
the Indenture on any of the mortgaged property.

         The Bonds of Series DDD will be subject to redemption (the  "Make-Whole
Redemption")  at the option of the Company at any time in whole, or from time to
time in part,  until  maturity,  upon not  less  than 30 nor more  than 60 days'
notice,  at a redemption  price equal to the sum of (i) the principal  amount of
the Bonds of Series DDD being redeemed plus accrued and unpaid interest  thereon
to the redemption  date, and (ii) the Make-Whole  Amount (as defined below),  if
any, with respect to such Bonds of Series DDD.

         "Make-Whole Amount" means, in connection with any Make-Whole Redemption
of any Bonds of Series DDD, the excess, if any, of (i) the sum, as determined by
a Quotation  Agent (as defined  herein),  of the present values of the principal
amount of such Bonds of Series DDD, together with scheduled payments of interest
from the redemption  date to the stated  maturity of the Bonds of Series DDD, in
each case discounted to the redemption  date on a semi-annual  basis (assuming a
360-day year  consisting of twelve 30-day months) at the Adjusted  Treasury Rate
(as  defined  herein)  over  (ii) 100% of the  principal  amount of the Bonds of
Series DDD to be redeemed.

         "Adjusted Treasury Rate" means, with respect to any redemption date for
a Make-Whole Redemption,  the rate per annum equal to the semi-annual equivalent
yield  to  maturity  of the  Comparable  Treasury  Issue  (as  defined  herein),
calculated  using a price for the  Comparable  Treasury  Issue  (expressed  as a
percentage of its principal  amount) equal to the Comparable  Treasury Price (as
defined herein) for such redemption  date,  calculated on the third business day
preceding the redemption date, plus 0.25% (25 basis points).

         "Comparable  Treasury Issue" means the United States Treasury  security
selected by the Quotation Agent as having a maturity comparable to the remaining
term from the redemption  date to the stated maturity of the Bonds of Series DDD
that  would  be  utilized,  at the  time of  selection  and in  accordance  with
customary financial practice, in pricing new issues of corporate debt securities
of comparable maturity to the remaining term of the Bonds of Series DDD.

     "Quotation  Agent"  means the  Reference  Treasury  Dealer  selected by the
Trustee after consultation with the Company. "Reference Treasury Dealer" means a
primary U.S. Government securities dealer.

         "Comparable  Treasury Price" means, with respect to any redemption date
for a Make-Whole Redemption, (i) the average of the bid and asked prices for the
Comparable  Treasury  Issue  (expressed  in  each  case as a  percentage  of its
principal  amount) on the third business day preceding such redemption  date, as
set forth in the daily statistical  release  designated "H.15" (or any successor
release)  published by the Board of Governors of the Federal  Reserve  System or
(ii) if such  release (or any  successor  release) is not  published or does not
contain  such prices on such  business  day,  (A) the  average of the  Reference
Treasury Dealer Quotations for such redemption date, after excluding the highest
and lowest such  Reference  Treasury  Dealer  Quotations,  or (B) if the Trustee
obtains fewer than three such Reference Treasury Dealer Quotations,  the average
of such Quotations.

         "Reference  Treasury  Dealer  Quotations"  means,  with respect to each
Reference  Treasury Dealer and any redemption date for a Make-Whole  Redemption,
the average, as determined by the Trustee (after consultation with the Company),
of the bid and asked prices for the Comparable Treasury Issue (expressed in each
case as a percentage of its principal  amount)  quoted in writing to the Trustee
by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third
business day preceding such redemption date.

         Notice of any redemption by the Company will be mailed at least 30 days
but not more than 60 days before any redemption  date to each holder of Bonds of
Series  DDD to be  redeemed.  If less than all the Bonds of Series DDD are to be
redeemed at the option of the Company,  the Trustee shall select, in such manner
as it shall deem fair and appropriate, the Bonds of Series DDD of such series to
be redeemed in whole or in part.

         Unless the Company defaults in payment of the redemption  price, on and
after any redemption date,  interest will cease to accrue on the Bonds of Series
DDD or portions thereof called for redemption.

         In the  case of any of  certain  events  of  default  specified  in the
Indenture,  the  principal  of this bond may be  declared  or may become due and
payable  prior to the stated date of maturity  hereof in the manner and with the
effect provided in the Indenture.

         No  recourse  shall  be had  for the  payment  of the  principal  of or
interest on this bond,  or for any claim based  hereon,  or otherwise in respect
hereof or of the Indenture, to or against any incorporator, shareholder, officer
or director,  past,  present or future,  of the Company or of any predecessor or
successor company, either directly or through the Company or such predecessor or
successor  company,  under any constitution or statute or rule of law, or by the
enforcement  of any assessment or penalty,  or otherwise,  all such liability of
incorporators, shareholders, directors and officers being waived and released by
the  registered  owner hereof by the  acceptance of this bond and being likewise
waived and released by the terms of the Indenture.

         The Bonds of Series DDD are issuable  only in  registered  form without
coupons.  This bond is transferable by the registered owner hereof, in person or
by attorney duly  authorized,  at the  principal  office or place of business of
LaSalle  National  Bank,  the  Trustee,  or its  successor  in trust  under  the
Indenture, or, at the option of the registered owner, at the office or agency of
the  Company in the  Borough of  Manhattan,  the City of New York,  State of New
York,  upon the  surrender  and  cancellation  of this  bond,  and upon any such
transfer a new registered bond or bonds of the same series and maturity date and
for the same  aggregate  principal  amount will be issued to the  transferee  in
exchange herefor.

         The Bonds of Series DDD are issuable in the  denomination of $1,000 and
in such  multiples  thereof  as  shall  from  time to  time  be  determined  and
authorized  by the Board of Directors of the Company.  In the manner and subject

exchangeable as between authorized denominations,  upon presentation thereof for

          stated maturity of the Bonds of Series BBB, CCC, and DDD that would be
          utilized,  at the time of selection and in accordance  with  customary
          financial practice, in pricing new issues of corporate debt securities

         release  designated 'H.15' (or any successor  release) published by the
         Board  of  Governors  of the  Federal  Reserve  System  or (ii) if such

         each Reference Treasury Dealer and any redemption date for a Make-Whole
         Redemption,   the  average,   as  determined  by  the  Trustee   (after
         consultation  with the  Company),  of the bid and asked  prices for the
         Comparable  Treasury  Issue  (expressed in each case as a percentage of
         its  principal  amount)  quoted  in  writing  to the  Trustee  by  such
         Reference  Treasury  Dealer at 5:00 p.m.,  New York City  time,  on the
         third business day preceding such redemption date.

               Notice of any  redemption  by the Company will be mailed at least
          30 days but not more than 60 days before any  redemption  date to each
          holder of Bonds of Series BBB,  CCC, and DDD to be  redeemed.  If less
          than all the Bonds of Series  BBB,  the  Bonds of Series  CCC,  or the
          Bonds of Series DDD (as  applicable)  are to be redeemed at the option
          of the Company,  the Trustee shall select,  in such manner as it shall
          deem  fair and  appropriate,  the Bonds of  Series  BBB,  the Bonds of
          Series CCC, or the Bonds of Series DDD (as  applicable) to be redeemed
          in whole or in part.

               Unless the Company  defaults in payment of the redemption  price,
          on and after any redemption date, interest will cease to accrue on the
          Bonds of Series  BBB,  CCC,  and DDD or  portions  thereof  called for
          redemption.

         attorneys'  fees),  court  costs,  judgments,  penalties,  obligations,
         suits,   disbursements   and  liabilities  of  any  kind  or  character
         whatsoever  which  may at any  time be  imposed  upon,  incurred  by or
         asserted  against the Trustee by reason of or arising out of or caused,
         directly or  indirectly  by any act or  omission  of the  Trustee  with
         respect to the  foregoing  Section  37,  including  without  limitation
         selection of any  Reference  Treasury  Dealer or  determination  of any
         Reference Treasury Dealer Quotations,  except for such that would arise
         out of the willful  misconduct  or gross  negligence of the Trustee and
         except for costs and  expenses  arising in the  ordinary  course of the
         Trustee's business.."

                             Recitals of the Company

         The Company has executed and  delivered the Indenture to the Trustee to

$97,342,000  (except  as  provided  in  Section  301(2) of the  Indenture).  The
Debentures shall mature and the principal shall be due and payable together with
all accrued and unpaid interest thereon on March 15, 2009 and shall be issued in
the form of a registered Global Security without coupons, registered in the name
of Cede & Co., as nominee of the Depository Trust Company (the "Depositary").

     Section 102. The  provisions of Section 305 of the Indenture  applicable to
Global Securities shall apply to the Debentures.

     Section  103.   Interest  on  each  of  the  Debentures  shall  be  payable

specified in the form of Debentures, from and including, April 30, 1999, or from
the most recent  Interest  Payment Date to which  interest has been paid or duly
provided for. The interest so payable, and punctually paid or duly provided for,
on any  Interest  Payment  Date will be paid to the  Person  in whose  name such
Debenture (or one or more Predecessor  Securities) is registered at the close of
business on March 1 or September 1 next preceding the Interest Payment Date. The
amount of  interest  payable  for any period  will be computed on the basis of a
360-day year of twelve 30-day months.

     Section 104.  Subject to agreements  with or the rules of the Depositary or
any  successor  book-entry  security  system or similar  system with  respect to

any integral multiple of $1,000.

defeasance,  at the Company's  option, as provided for in Sections 1302 and 1303

the Company shall have the right to redeem the Debentures,  at any time in whole
or from time to time in part, until maturity,  (such  redemption,  a "Make-Whole
Redemption", and the date thereof, the "Redemption Date"), upon not less than 30

(as defined below), if any, with respect to the Debentures being redeemed.

         "Make-Whole Amount" means, in connection with any Make-Whole Redemption
of any  Debentures,  the  excess,  if any, of (i) the sum,  as  determined  by a

of such  Debentures,  together  with  scheduled  payments of  interest  from the
Redemption  Date  to  the  Stated  Maturity  of the  Debentures,  in  each  case
discounted to the  Redemption  Date on a semi-annual  basis  (assuming a 360-day
year  consisting  of twelve  30-day  months) at the Adjusted  Treasury  Rate (as
defined  herein) over (ii) 100% of the principal  amount of the Debentures to be
redeemed.

         "Adjusted Treasury Rate" means, with respect to any Redemption Date for
a Make-Whole Redemption,  the rate per annum equal to the semi-annual equivalent
yield to maturity of the Comparable Treasury Issue, calculated using a price for
the  Comparable  Treasury  Issue  (expressed  as a percentage  of its  principal
amount)  equal  to the  Comparable  Treasury  Price  for such  Redemption  Date,
calculated on the third business day preceding the Redemption Date, plus in each
case 0.20% (20 basis points).

         "Comparable  Treasury Issue" means the United States Treasury  security
selected by the Quotation Agent as having a maturity comparable to the remaining
term from the  Redemption  Date to the Stated  Maturity of the  Debentures  that
would be utilized,  at the time of selection  and in accordance  with  customary
financial  practice,  in pricing  new issues of  corporate  debt  securities  of
comparable maturity to the remaining term of the Debentures.

     "Quotation  Agent"  means the  Reference  Treasury  Dealer  selected by the
Trustee after consultation with the Company. "Reference Treasury Dealer" means a
primary U.S. Government securities dealer.

         "Comparable  Treasury Price" means,  with respect to the any Redemption
Date for a  Make-Whole  Redemption,  (i) the average of the bid and asked prices
for the Comparable Treasury Issue (expressed in each case as a percentage of its
principal  amount) on the third business day preceding such Redemption  Date, as
set forth in the daily statistical  release  designated "H.15" (or any successor
release)  published by the Board of Governors of the Federal  Reserve  System or
(ii) if such  release (or any  successor  release) is not  published or does not
contain  such prices on such  business  day,  (A) the  average of the  Reference
Treasury Dealer Quotations for such Redemption Date, after excluding the highest
and lowest such  Reference  Treasury  Dealer  Quotations,  or (B) if the Trustee
obtains fewer than three such Reference Treasury Dealer Quotations,  the average
of such Quotations.

         "Reference  Treasury  Dealer  Quotations"  means,  with respect to each
Reference  Treasury Dealer and any Redemption Date for a Make-Whole  Redemption,
the average,  as determined by the Trustee,  of the bid and asked prices for the
Comparable  Treasury  Issue  (expressed  in  each  case as a  percentage  of its
principal  amount) quoted in writing to the Trustee by such  Reference  Treasury
Dealer at 5:00 p.m.,  New York City time,  on the third  business day  preceding
such Redemption Date.

This  Security is one of a duly  authorized  issue of  securities of the Company
(herein called the "Securities"),  issued and to be issued in one or more series
under  an  Indenture,   dated  as  of  November  15,  1996  (herein  called  the
"Indenture",  which  term  shall  have  the  meaning  assigned  to  it  in  such
instrument), between the Company and Fifth Third Bank, as Trustee (herein called
the "Trustee",  which term includes any successor  trustee under the Indenture),
and reference is hereby made to the Indenture for a statement of the  respective
rights,  limitations of rights, duties and immunities thereunder of the Company,
the Trustee and the  Holders of the  Securities  and of the terms upon which the
Securities are, and are to be, authenticated and delivered. This Security is one
of the series  designated  on the face hereof,  limited in  aggregate  principal
amount to $97,342,000.

The  Indenture  contains  provisions  for  defeasance  at any time of the entire
indebtedness  of this  Security or certain  restrictive  covenants and Events of
Default with respect to this Security upon  compliance  with certain  conditions
set forth in the Indenture.

The Securities of this series are subject to optional  redemption at any time in
whole  or from  time to  time in  part,  until  maturity,  (such  redemption,  a
"Make-Whole Redemption",  and the date thereof, the "Redemption Date"), upon not
less than 30 nor more than 60 days' notice to the holders, at a redemption price
equal to the sum of the principal  amount of the Debentures  being redeemed plus
accrued  and  unpaid  interest  thereon  to the  Redemption  Date,  and (ii) the
Make-Whole  Amount (as defined  below),  if any, with respect to the  Debentures
being redeemed.

Debentures,  the excess,  if any, of (i) the sum, as  determined  by a Quotation
Agent (as defined  herein) of the present value of the principal  amount of such
Debentures,  together with  scheduled  payments of interest from the  Redemption
Date to the Stated  Maturity of the  Debentures,  in each case discounted to the
Redemption  Date on a semi-annual  basis  (assuming a 360-day year consisting of
twelve 30-day  months) at the Adjusted  Treasury  Rate (as defined  herein) over
(ii) 100% of the principal amount of the Debentures to be redeemed.

"Adjusted  Treasury  Rate"  means,  with  respect to any  Redemption  Date for a
Make-Whole  Redemption,  the rate per annum equal to the semi-annual  equivalent
yield to maturity of the Comparable Treasury Issue, calculated using a price for
the  Comparable  Treasury  Issue  (expressed  as a percentage  of its  principal
amount)  equal  to the  Comparable  Treasury  Price  for such  Redemption  Date,
calculated on the third business day preceding the Redemption Date, plus in each
case 0.20% (20 basis points).

"Comparable  Treasury Issue" means the United States Treasury  security selected
by the Quotation  Agent as having a maturity  comparable  to the remaining  term
from the Redemption  Date to the Stated Maturity of the Debentures that would be
utilized,  at the time of selection and in accordance  with customary  financial
practice,  in pricing new issues of  corporate  debt  securities  of  comparable
maturity to the remaining term of the Debentures.

"Quotation  Agent" means the Reference  Treasury  Dealer selected by the Trustee
after consultation with the Company. "Reference Treasury Dealer" means a primary
U.S. Government securities dealer.

"Comparable Treasury Price" means, with respect to the any Redemption Date for a
Make-Whole  Redemption,  (i) the  average  of the bid and asked  prices  for the
Comparable  Treasury  Issue  (expressed  in  each  case as a  percentage  of its
principal  amount) on the third business day preceding such Redemption  Date, as
set forth in the daily statistical  release  designated "H.15" (or any successor
release)  published by the Board of Governors of the Federal  Reserve  System or
(ii) if such  release (or any  successor  release) is not  published or does not
contain  such prices on such  business  day,  (A) the  average of the  Reference
Treasury Dealer Quotations for such Redemption Date, after excluding the highest
and lowest such  Reference  Treasury  Dealer  Quotations,  or (B) if the Trustee
obtains fewer than three such Reference Treasury Dealer Quotations,  the average
of such Quotations.

"Reference  Treasury Dealer  Quotations"  means,  with respect to each Reference
Treasury  Dealer  and any  Redemption  Date  for a  Make-Whole  Redemption,  the
average,  as  determined  by the  Trustee,  of the bid and asked  prices for the
Comparable  Treasury  Issue  (expressed  in  each  case as a  percentage  of its
principal  amount) quoted in writing to the Trustee by such  Reference  Treasury
Dealer at 5:00 p.m.,  New York City time,  on the third  business day  preceding
such Redemption Date.

If an Event of Default with respect to Securities of this series shall occur and
be  continuing,  the principal of the  Securities of this series may be declared
due and payable in the manner and with the effect provided in the Indenture.

The  Indenture  permits,  with  certain  exceptions  as  therein  provided,  the
amendment  thereof and the  modification  of the rights and  obligations  of the
Company  and the rights of the  Holders of the  Securities  of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in principal  amount of the  Securities  at
the time outstanding of each series to be affected.  The Indenture also contains
provisions  permitting  the  Holders of a majority  in  principal  amount of the
Securities of each series at the time  outstanding,  on behalf of the Holders of
all Securities of such series,  to waive  compliance by the Company with certain
provisions of the  Indenture  and certain past defaults  under the Indenture and
their  consequences.  Any such consent or waiver by the Holder of this  Security
shall be conclusive  and binding upon such Holder and upon all future Holders of
this  Security  and of any  Security  issued upon the  registration  of transfer
hereof or in exchange herefor or in lieu hereof, whether or not notation of such
consent or waiver is made upon this Security.
