                         Cost Apportionment Methodology

         Section 5.1. General Principles. The following general principles shall
be used in setting charges for transactions between ComEd and Unicom Entities:

                  (a) Sales of Assets.  Asset sales  between  ComEd and a Unicom
         Entity shall be charged by the Selling Party to the Acquiring Party at:
         (i) the fair market value of the transferred asset, as evidenced by (1)
         the  prevailing  price for which the same or similar assets are offered
         for sale to the general  public by the Selling Party (e.g.,  for ComEd,
         the tariffed charge or other pricing mechanism approved by the ICC) or,
         if  no  such   prevailing   price  exists,   (2)  the  price  at  which
         nonaffiliated  vendors  offer the same or  similar  assets  for sale by
         reference to quoted  market  prices,  independent  appraisals  or other
         objectively  determinable  evidence or, if no such fair market value is
         objectively or practicably  determinable,  (ii) the historical  cost of
         the asset to the Selling Party, less all applicable valuation reserves.

                  (b) Use of Facilities or Services.

                           (i)  Facilities  or  services  provided by ComEd to a
                  Unicom  Entity  shall  be  charged  by  the  Provider  to  the
                  Requestor at: (1) the prevailing  price for which the facility
                  or service is provided  for sale to the general  public by the
                  Provider (i.e.,  the tariffed rate or other pricing  mechanism
                  approved by the ICC) or, if no such  prevailing  price exists,
                  (2) the fully  distributed  cost  (determined  as  provided in
                  Section  5.2)  incurred  by the  Provider  in  providing  such
                  facility or service to the Requestor.

                           (ii)  Facilities  or  services  provided  by a Unicom
                  Entity  to  ComEd  shall be  charged  by the  Provider  to the
                  Requestor at: (1) the prevailing  price for which the facility
                  or service is provided for sale to the general public by

                  the Provider (i.e., the price charged to nonaffiliates if such
                  transactions  with  nonaffiliates   constitute  a  substantial
                  portion  of such  Unicom  Entity's  total  revenues  from such
                  transactions)  or, if no such prevailing price exists,  (2) an
                  amount not to exceed the fully distributed cost (determined as
                  provided in Section 5.2)  incurred in providing  such facility
                  or service.

                  (c) Sales of Intangible Assets. Intangible Asset sales between
         ComEd and a Unicom  Entity shall be charged by the Selling Party to the
         Acquiring  Party (i) under a mechanism to reflect the fair market value
         of the asset as  determined  by an appraisal or other fair market value
         study or, if no such fair market value is  objectively  or  practicably
         determinable,  (ii) at the fully  distributed cost incurred to purchase
         or develop the asset,  adjusted to reflect imputed  depreciation of, if
         applicable, and carrying costs on the unrecorded asset.

Costs shall be charged to a Party in accordance  with these  general  principles
using either a direct  charge or an allocation  methodology.  Costs of assets or
services specifically attributable to a Party should be charged directly to such
Party. Joint and common costs not specifically attributable to a Party should be
charged to the appropriate Parties based on specific  allocation  methodologies.
The Parties  intend to develop  and  implement  a set of  guidelines  to address
applications of the foregoing general principles.

         Section  5.2.  Fully  Distributed  Costs.  Costs  charged  on  a  fully
distributed  cost  basis  shall  reflect  the  amounts of direct  labor,  direct
materials and direct  purchased  services  associated  with the related asset or
service as provided in subsections (a) and (b). These amounts shall be increased
by a portion of indirect costs to reflect labor,  administrative and general and
other overhead amounts as provided in subsection (c).

                  (a)  Direct  Costs.   Costs  incurred  that  are  specifically
         attributable  to a Party shall be directly  charged to the  appropriate
         function.

                           (i) Direct Labor.  Amounts of direct labor charged to
                  a Party shall be based on an  employee's  actual  direct labor
                  rate,  reflecting  the effects of overtime and  non-productive
                  time.

                           For most employees,  direct labor shall be charged to
                  a Party  under a positive  time  reporting  methodology  under
                  which an employee  shall  report each pay period the number of
                  hours incurred in performing  activities for such Party. Based
                  on  the  time   reported   each  pay  period,   the   regular,
                  predetermined  account  distribution for the employee shall be
                  adjusted to reflect the  distribution  of direct labor charges
                  to the appropriate affiliate function.

                           Some  departments  or  organizations  are expected to
                  provide a recurring,  predictable level of services to a Party
                  or Parties.  For these  departments or  organizations,  annual
                  reviews shall be performed to determine a normal  distribution
                  of time to such Party or Parties. The distribution percentages
                  derived from such reviews  shall then be used to allocate time
                  with  respect to each pay  period.  For these  departments  or
                  organizations,  direct  labor  shall be  charged to a Party or
                  Parties under an exception  time reporting  methodology.  That
                  is,  significant  deviations  of actual  activity  from  these
                  predetermined  percentages  shall be reported and shall result
                  in adjustments  to the  predetermined  distribution  of direct
                  labor charges to the affiliate functions.

                           Officers  of  each  Party   shall  also   utilize  an
                  exception time reporting methodology. Distribution percentages
                  derived from an annual  review for each Officer  shall be used
                  to allocate time with respect to each pay period.  Significant
                  deviations   of  actual   activity   from  the   predetermined
                  percentages  shall be reported and shall result in adjustments
                  to the  predetermined  distribution of direct labor charges to
                  the affiliate functions.

                           Overtime shall be reflected in the direct labor rates
                  charged to a Party.  For  bargaining  unit  employees,  direct
                  labor  shall be  charged  based on the base and  overtime  pay
                  amounts   actually   incurred   under  a  Party's   collective
                  bargaining agreements.  Likewise, for management employees who
                  are  compensated  for overtime,  direct labor shall be charged
                  based on the actual pay amounts  incurred for such  employees,
                  including overtime.  For management  employees not compensated
                  for  overtime,  direct labor  charges to  affiliates  shall be
                  adjusted,  on  a  departmental  or  organizational  basis,  to
                  reflect  estimated  overtime  incurred  based  on an  overtime
                  review performed annually.

                           All direct  labor  charges  shall be  increased  by a
                  factor to reflect  nonproductive  time. The nonproductive time
                  factor shall be developed annually based on a review of actual
                  nonproductive   time  incurred  for  the  previous  year.  The
                  nonproductive time factor reflects time incurred for training,
                  vacations,  holidays,  disability,  jury duty and  other  paid
                  absences.

                           (ii) Direct Materials and Purchased Services. Amounts
                  incurred  for   materials  or  purchased   services   directly
                  attributable  to a Party  shall  be  charged  directly  to the
                  appropriate  function  for that Party using  standard  voucher
                  account distribution procedures.

<PAGE>
                           (iii)  Costs  of  Facilities,  Equipment,  Machinery,
                  Furniture and Fixtures.  The costs  allocated to any Party for
                  the  use  of  a  Party's  facilities,   equipment,  machinery,
                  furniture or fixtures  shall  include an amount to reflect the
                  cost  of  such   assets   (e.g.,   depreciation,   operations,
                  maintenance,  etc.)  and,  for owned  assets or assets  leased
                  under capital leases,  a return equal to the rate of return on
                  rate base most recently allowed to ComEd by the ICC.

                  (b) Allocated Costs.  Costs incurred that are not specifically
         attributable  to a Party but that  have  joint  benefit  to two or more
         Parties  shall  be  charged  to  the  appropriate  functions  based  on
         specified allocation  methodologies.  The allocation methodologies used
         shall be  reasonably  based on cost  causative  measures  to  ensure an
         equitable allocation among such Parties.

                  (c) Indirect Costs. The direct and allocated costs apportioned
         to a Party or Parties  shall be  increased to reflect  indirect  labor,
         administrative  and general and other overhead amounts.  These indirect
         costs are not  specifically  identifiable or attributable to the direct
         costs incurred on behalf of a Party.

                           (i)  Labor   Loading.   All  direct   labor   charges
                  apportioned to a Party (either  apportioned  directly or using
                  an  allocation  methodology)  shall be  increased by a loading
                  factor to reflect indirect labor-driven costs. For each Party,
                  this loading  factor  shall be  determined  annually  based on
                  actual indirect labor-driven charges incurred during the prior
                  year as a percentage of total direct labor charges incurred in
                  that year.  The labor loading rate pool shall include  payroll
                  taxes; medical, dental and vision insurance costs; pension and
                  other  postretirement  health care benefits  costs;  incentive
                  compensation  plan costs;  employee  savings plans' costs; and
                  other labor-driven costs such as payroll department,  employee
                  benefits   department,   mailroom,   office   facilities   and
                  non-customer related postage costs.

                           (ii) Information  Systems  Loading.  All direct labor
                  costs  apportioned  to a Party shall be increased by a loading
                  factor to reflect information systems related costs associated
                  with  mainframe and local area network  usage and  operations,
                  hardware and software costs and  telecommunications  services.
                  For each  Party,  this  loading  factor  shall be based on the
                  actual costs incurred during the prior year as a percentage of
                  the  corresponding  actual total direct labor charges incurred
                  in that year.

                           (iii) Common Costs Loading.  All direct labor, direct
                  materials,  direct purchased services and indirect labor costs
                  (including   the   information    systems   loading   amounts)
                  apportioned to a Party shall be increased by a

                  loading factor to reflect administrative and general and other
                  overhead amounts, including the overhead costs of each Party's
                  information  systems  function.  For each Party,  this loading
                  factor   shall  be   determined   annually   based  on  actual
                  administrative and general and other overhead charges incurred
                  during  the  prior  year  as  a  percentage  of  actual  total
                  operations and maintenance  expense incurred in that year. The
                  common  costs  loading  rate  pool  shall  include  costs  for
                  departments  that  support  other   departments  that  provide
                  services  directly  to a Party.  In addiion to the general and
                  administrative  costs  of the  information  systems  function,
                  representative  costs in the common  costs pool shall  include
                  printing and duplicating services,  forms and office supplies,
                  communications  services,  library  services and other similar
                  costs.

         Section 5.3. Costs Charged to/from Unicom. Unicom shall maintain unique
function numbers in its general ledger system:  Consolidated  Pool functions (as
described in Section  5.3(a)) and  Unallocated  Pool  functions (as described in
Section 5.3(b)).  All apportioned and billed to Unicom by other Parties shall be
charged to one of these two types of functions.

                  (a) Consolidated  Pool. The Consolidated Pool shall be charged
         with costs  related  to  activities  that  jointly  benefit  all of the
         Parties.  Each month, the costs  accumulated in the  Consolidated  Pool
         shall be  apportioned  and billed to the Parties  (other  than  Unicom)
         using a two(amendment 1) factor formula  methodology.  A representative
         listing of the types of  services  for which  costs shall be charged to
         the Consolidated Pool is as follows:

                Corporate Services

                  (b) Unallocated  Pool. The  Unallocated  Pool shall be charged
         with  costs  that  have  been   determined  as  not   appropriate   for
         apportionment  by Unicom to the other  Parties.  These costs  primarily
         relate  to  Unicom's   diversification,   political  and  philanthropic
         activities. A representative listing of the types of services for which
         costs shall be charged to the Unallocated Pool is as follows:

                Advertising
                Corporate Relations
                        Philanthropy
                        Political Advocacy
                        Public Relations

                        Marketing
                        Research and Development
                        Strategic Analysis

                  (c) Two Factor Formula Methodology.  Monthly, costs charged to
         the Consolidated  Pool shall be apportioned and billed by Unicom to the
         other Parties  based on a two factor  formula  methodology.  Under this
         approach,  each such Party is allocated and billed for a portion of the
         total  costs  in the  Consolidated  Pool  based on an  average  of such
         Party's  gross  payroll  and  total  asset  amounts   relative  to  the
         corresponding averages for the other parties. To adjust for seasonality
         in operations,  the gross payroll amount used in this allocation  shall
         be the most  recent  twelve-month  period  for  which  such  figure  is
         available.  The total asset  amount  shall  reflect  the average  total
         assets for the month  being  allocated.  Total  assets  shall  include,
         without limitation,  cash,  investments,  accounts receivable,  the net
         book value of property,  plant and equipment and nuclear fuel, coal and
         material and supplies inventories, as applicable. (amendment 1)

         Assets  pursuant to Article III,  the Selling  Party shall be deemed to
         have  represented  and warranted to the Acquiring Party that: (i) title
         conveyed  is good,  (ii)  conveyance  of such title is  authorized  and
         rightful,  and  (iii) the  title so  conveyed  is free and clear of all
         liens,  claims,  encumbrances  or  security  interests  of  persons  or
         entities claiming by or through the Selling Party,  except, in the case
         of this clause (iii),  as the Acquiring Party and the Selling Party may
         otherwise agree.

         Section 6.3. No  Partnership.  The Parties  acknowledge  and agree that
this Agreement does not create a partnership  between,  or a joint venture of, a

         Section 7.2. Termination.  Any Party may terminate this Agreement as to
it by providing at least 30 days prior  written  notice to the other  Parties of
the  effective  date of such  termination.  In addition,  this  Agreement  shall

         Each Party shall treat in  confidence  all  information  which it shall
have obtained regarding the other Parties and their respective businesses during

                                  Miscellaneous

         Section 9.1. Entire  Agreement;  Amendments.  Upon its effectiveness as
provided in Section 7.1, this  Agreement  shall  constitute  the sole and entire
agreement  among the Parties with respect to the subject matter hereof and shall
supersede all previous  agreements,  proposals,  oral or written,  negotiations,
representations, commitments and all other communications between some or all of
the  Parties.  Except as provided in Section 9.2 with respect to new Parties and
except  that  Unicom  may  amend  Exhibit  A to this  Agreement  to  delete  any
terminated Party, this Agreement shall not be amended,  modified or supplemented
except by a written instrument signed by an authorized representative of each of
the Parties hereto.

         Section 9.2.  New  Parties.  Any other entity which is or may become an
affiliate of Unicom or any of the other  Parties to this  Agreement may become a
party to this Agreement by executing an agreement  adopting all of the terms and
conditions of this  Agreement.  Such agreement must be signed by Unicom in order
to  become  effective,  but  need  not be  signed  by any  other  Party  to this
Agreement.  Upon such  execution by Unicom,  such entity shall be deemed to be a
Party and shall be included  within the  definition  of "Party" for all purposes
hereof, and Exhibit A shall be amended to add such entity. Before such execution
by Unicom,  ComEd shall  provide the staff of the ICC with thirty  days'  notice
that  another  Party  will  be  added  to this  Agreement.  (ALSO  SEE  ATTACHED
STIPULATION)

         Section  9.3.  Assignment.  This  Agreement  may not be assigned by any
party without the prior written consent of Unicom.

         Section 9.4.  Access to Records.  During the term of this Agreement and
for a period  of  seven  years  after  the  expiration  or  termination  of this
Agreement  as to a Party,  such Party  shall have  reasonable  access to and the
right to examine any and all books, documents,  papers and records which pertain
to services and facilities provided by the other Parties under this Agreement to
such  Party,  and such Party shall  provide  access to, and the  opportunity  to
examine,  all such records which pertain to services and facilities  provided to
the other Parties under this Agreement by such Party.  Each Party shall maintain
all such records for a period of seven years after  expiration or termination of
this Agreement as to such Party. In addition,  during the term of this Agreement
and for a period of seven  years after the  expiration  or  termination  of this
Agreement  as to a Unicom  Entity,  the ICC shall  have  access to the books and
records of such  Unicom  Entity as set forth in the Order  entered by the ICC in
Docket No. 95-0615 on March 12, 1997. (AMENDMENT 1)

         Section 9.5.  Partial  Invalidity.  Wherever  possible,  each provision
hereof shall be  interpreted  in such manner as to be effective  and valid under
applicable law, but in case any one or more of the provisions  contained  herein
shall,  for any reason,  be held to be invalid,  illegal or unenforceable in any
respect,  such provision  shall be  ineffective  to the extent,  but only to the
extent, of such invalidity,  illegality or unenforceability without invalidating
the remainder of such invalid,  illegal or unenforceable provision or provisions
or  any  other  provisions   hereof,   unless  such  a  construction   would  be
unreasonable.  In the  event  that  it is  determined  that  the  charges  for a
particular  transaction  covered by this Agreement were not determined  properly
for any reason, such determination  and/or finding shall not affect the validity
of such transaction;  provided,  however, that if the transaction involved ComEd
and a Unicom Entity,  Unicom (or, if Unicom so  determines,  such Unicom Entity)
shall pay to or reimburse  ComEd, or ComEd shall pay to or reimburse such Unicom
Entity,  as the case may be, for the  difference  between  the  amount  that was
charged in connection  with the transaction and the charge that is determined to
be proper under the provisions of Article V.

         Section  9.6.  Waiver.  Failure  by any  Party to  insist  upon  strict
performance of any term or condition  herein shall not be deemed a waiver of any
rights or remedies  that such Party may have  against any other Party nor in any
way to affect the validity of this  Agreement or any part hereof or the right of
such Party thereafter to enforce each and every such provision. No waiver of any
breach of this  Agreement  shall be held to  constitute a waiver of any other or
subsequent breach.

         Section  9.7.  Governing  Law.  This  Agreement  shall be governed  by,
construed and interpreted pursuant to, the laws of the State of Illinois.

                               ARES CERTIFICATION

                                   AMENDMENT A
                        TO AFFILIATED INTERESTS AGREEMENT


            Unicom Corporation, an Illinois corporation ("Unicom"), Commonwealth
Edison  Company,  an Illinois  corporation  ("ComEd"),  and each of the entities
identified from time to time on Exhibit A to the Affiliated  Interests Agreement
dated as of December 4, 1995 (the "Agreement"),  hereby agree that the Agreement
is amended, pursuant to Section 9.1 of the Agreement, as follows:

         1.  The  purposes  and  intent  of  this  amendment  are to  set  forth
procedures and policies to govern: (a) transactions  between Unicom Energy, Inc.
("Unicom Energy"),  ComEd's "affiliated interest in competition with alternative
retail  electric  suppliers,"  as that term is defined by 83 Ill.  Adm. Code ss.
450.10 (as amended from time to time),  and ComEd's  "affiliated  interests"  as
that term is defined by Section  7-101 of the Public  Utilities  Act (the "Act")
(220 ILCS  5/7-101))  and which  are  parties  to the  Agreement,  whether  such
transactions  occur  directly  or  indirectly  as the end  result of a series of
related  transactions;  and (b) the  allocation of certain joint service  costs.
Notwithstanding  subparts (a) and (b), this  amendment is not intended to govern
transactions  between Unicom Energy and ComEd's  affiliated  interests which are
parties  to the  Agreement  except  to the  extent  required  by Part 450 of the
Illinois  Commerce   Commission's  rules  on   Non-Discrimination  In  Affiliate
Transactions  For Electric  Utilities  (83 Ill.  Adm.  Code ss. 450 et seq.) (as
amended from time to time).

         2. Any transaction  between Unicom Energy and an affiliated interest of
ComEd that is a party to the Agreement shall be on whatever terms and conditions
Unicom  Energy  and the  affiliated  interest  agree  to,  except  that if ComEd
provided some or all of the facilities  and services to the affiliated  interest
that  are the  subject  of the  transaction,  then  (a)  the  pricing  of  those
facilities  and  services  shall be at the same  price as if ComEd had  directly
provided the facilities and services to Unicom Energy,  i.e., in accordance with
the Agreement  and (b) the transfer of those  facilities  and services  shall be
recorded  in  accordance  with the cost  allocation  guidelines  and  accounting
conventions set forth in the Agreement.

         3.  Nothing in this  amendment  should be  construed  as an  admission,
concession,  or recognition by ComEd,  Unicom Energy,  or any other signatory to
the Agreement and this Amendment A that the Illinois Commerce Commission has the
authority and/or jurisdiction to regulate transactions between Unicom Energy and
ComEd's "affiliated  interests," as that term is defined by Section 7-101 of the

                    SUBSIDIARY AFFILIATED INTERESTS AGREEMENT


            Unicom Energy,  Inc. ("Unicom Energy"),  Commonwealth Edison Company
("ComEd"),  and the subsidiaries of ComEd,  Commonwealth  Research  Corporation,
Concomber Ltd., Edison  Development  Company,  Edison  Development  Canada Inc.,
ComEd of Indiana,  Inc.,  ComEd Funding LLC, ComEd  Transitional  Funding Trust,
Cotter Corporation,  ComEd Financing I, and ComEd Financing II (collectively the
"Subsidiaries") hereby agree as follows:

            1. The purposes and intent of this agreement ( the "SAIA Agreement")
are to set forth  procedures and policies to govern:  (a)  transactions  between
Unicom Energy,  ComEd's  "affiliated  interest in competition  with  alternative
retail  electric  suppliers,"  as that term is defined by 83 Ill.  Adm. Code ss.
450.10 (as amended from time to time), and ComEd's  Subsidiaries as that term is
defined above, whether such transactions occur directly or indirectly as the end
result of a series of related  transactions;  and (b) the  allocation of certain
joint service costs. Notwithstanding subparts (a) and (b), this amendment is not
intended to govern transactions  between Unicom Energy and ComEd's  Subsidiaries
except to the extent required by Part 450 of the Illinois Commerce  Commission's
rules on Non-Discrimination In Affiliate Transactions For Electric Utilities (83
Ill. Adm. Code ss. 450 et seq.) (as amended from time to time).

            2. Any  transaction  between Unicom Energy and ComEd's  Subsidiaries
shall be on whatever  terms and  conditions  Unicom Energy and the  Subsidiaries
agree  to,  except  that if ComEd  provided  some or all of the  facilities  and
services to the ComEd subsidiary that are the subject of the  transaction,  then
(a) the pricing of those  facilities  and services shall be at the same price as
if ComEd had directly  provided the  facilities  and services to Unicom  Energy,
i.e., in accordance with the Agreement and (b) the transfer of those  facilities
and services shall be recorded in accordance with the cost allocation guidelines
and accounting  conventions set forth in ComEd's Affiliated  Interests Agreement
dated as of December 4, 1995..

            3.  Nothing  in  this  SAIA  Agreement  should  be  construed  as an
admission,  concession,  or  recognition  by ComEd,  Unicom  Energy,  or ComEd's
Subsidiaries  that the Illinois  Commerce  Commission  has the authority  and/or
jurisdiction  to regulate  transactions  between Unicom Energy and  Commonwealth
Edison Company's  "affiliated  interests,"  including the Subsidiaries,  as that
term is defined by Section 7-101 of the Act (220 ILCS 5/7-101).

                                   STIPULATION

         The  Staff  of  the  Illinois   Commerce   Commission   ("Staff")   and
Commonwealth Edison Company ("ComEd") hereby stipulate and agree as follows:

         1.  Among  the  issues  addressed  in this  proceeding  is the issue of
whether a new ComEd  affiliate  may  become a party to the  Affiliated  Interest
Agreement  ("AIA")  without  ComEd  first  obtaining  separate  approval  of the
Illinois Commerce Commission

         2. With respect to his issue, Staff and ComEd hereby agree as follows:

     (a) As  currently  provided  in  the  ALA  and  ComEd's  Petition  in  this
         proceeding,  ComEd will offer  information  to Staff about the proposed
         new affiliate and the projected type and frequency of transactions with
         that affiliate 30 days before that new affiliate will become a party to
         the AIA. The  provision  of this  information  will  commence a "30-day
         review period" during which Staff may investigate whether
--------------------------------------------------------------------------------
                                                                         Page 72
<PAGE>


         the provision of facilities and services to the new affiliate under the
         terms of the AIA "is not in the public  interest" within the meaning of
         Section 7-101 of the Public Utilities Act.

     (b) If, at any time prior to the  expiration of the 30-day  review  period,
         Staff  notifies ComEd that it believes that the provision of facilities
         and services to the new affiliate  under the terms of the AIA is not in
         the public  interest  within the meaning of Section 7-101 of the Public
         Utilities  Act,  ComEd must file a petition at the  Commission  seeking
         resolution  of the  issues  raised by Staff  within 30 days of  Staff's
         notice.  Regardless of whether Staff so notifies ComEd, however, at the
         expiration  of the 30-day  review  period,  the  affiliate may become a
         party to the AIA and engage in transactions  with ComEd under the terms
         of the AIA unless and until ordered otherwise by the Commission after a
         hearing on ComEd's petition pursuant to this section.

     (c) If Staff does not notify  ComEd  before  the  expiration  of the 30-day
         review period that Staff  believes that the provision of facilities and
         services to the new affiliate  under the terms of the AIA is not in the
         public  interest  within the  meaning  of  Section  7-101 of the Public
         Utilities  Act,  ComEd will file at the  Commission  as a  Supplemental
         Report  in this  docket  information  about the new  affiliate  and the
         projected type and frequency of transactions, substantially in the form
         attached to ComEd's  petition in this  proceeding  as  Attachment B. At
         that time, the affiliate

         may  become a party to the AIA and  engage in  transactions  with ComEd
         under the AIA.

     (d) At the end of the first 12-month  period after a new affiliate has been
         added to the AIA,  ComEd will file with the Commission in this docket a
         second  Supplemental  Report  showing the actual type and  frequency of
         transactions with that affiliate over the previous 12 months, including
         a listing of any asset  transfers and ComEd's  monthly  billings to the
         affiliate.

         3. Staff and ComEd agree that these procedural  provisions are adequate
to enforce the requirement that transactions between ComEd and its affiliates do
not  adversely  affect the  public  interest  within  the  meaning of the Public
Utilities Act.
