                   THE CONSOLIDATED EDISON THRIFT SAVINGS PLAN

                                  INTRODUCTION

     The purpose of the Consolidated Edison Thrift Savings Plan (the "Plan") is
to establish a convenient way for each eligible employee of the parent company,
Consolidated Edison, Inc. (the "Company" and/or "CEI") and of certain of the
controlled group affiliates of CEI, to supplement his or her retirement income
by saving on a regular and long-term basis, while concurrently offering each
employee an additional incentive to continue his or her career with the Company.
The Plan is intended to satisfy the requirements of the Internal Revenue Code of
1986, as amended (the "Code"), Sections 401(k) and 401(m) and to qualify under
Section 401(a). The trust established under and as a part of the Plan is
intended to qualify under Code Section 501(a). The Plan and its trust provide
each Participant with an opportunity to defer a portion of his or her
compensation and to invest and reinvest that deferred savings under the Plan on
a tax-deferred basis. It is intended that a Participant's Pre-Tax contributions,
as defined in the Plan, shall constitute payments by each Employer as
contributions to the trust fund on behalf of the Participant, within the meaning
of Code Section 401(k).

     The Plan was originally established and made effective on January 1, 1987,
by the Consolidated Edison Company of New York, Inc. ("CECONY") as the
Consolidated Edison Retirement Income Savings Plan for Weekly Employees ("CECONY
Weekly Plan"). Thereafter, the CECONY Weekly Plan was amended from time to time.
On December 1, 1996, the CECONY Weekly Plan was amended and restated in its
entirety, among other

                                                                               1

reasons, to make a transition from Bankers Trust Company as trustee and record
keeper to Vanguard Fiduciary Trust Company.

     Effective January 1, 1998, CEI was formed and CECONY became a subsidiary
corporation of CEI. From time to time thereafter, wholly-owned affiliates of CEI
were formed and together with CEI create a controlled group, as defined in Code
Section 414(b), in which CEI is the parent corporation. In July 1999, CEI
acquired Orange and Rockland Utilities, Inc. ("O&R").

     On July 20, 2000, for administrative ease, to facilitate the transfer of
employees from one affiliate to another, and to reduce the cost of operational
expenses, the Board of Trustees of CECONY and the Board of Directors of O&R
approved the merger ("Merger"), effective January 1, 2001, of the following
plans into the CECONY Weekly Plan:

            (i)   the Consolidated Edison Thrift Savings Plan for Management
                  Employees (the "CECONY Management Plan");

            (ii)  the Orange and Rockland Utilities, Inc. Management Employees
                  Savings Plan (the "O&R Management Plan") and

            (iii) the Orange and Rockland Utilities, Inc. Hourly Group Savings
                  Plan (the "O&R Hourly Plan".

     The CECONY Weekly Plan, the CECONY Management Plan, the O&R Management Plan
and the O&R Hourly Plan are called the Prior Plans.

     The CECONY Weekly Plan, renamed the Consolidated Edison Thrift Savings
Plan, was also amended, effective January 1, 2001, to take into account the
Merger, among other things, and restated constitutes the single plan and a
continuation of each one of the Prior Plans.

                                                                               2
<Page>

     In the Plan, CEI is the Company, CECONY is the Plan Sponsor and an
Employer, O&R is an Employer, and certain existing and future affiliates are, or
will become, Employers.

     The Plan is amended for the Family and Medical Leave Act of 1993, the
Uniformed Services Employment and Reemployment Rights Act of 1993, the
Retirement Protection Act of 1994, as enacted under the Uruguay Round Agreements
Act (General Agreement on Tariffs and Trade), the Small Business Job Protection
Act of 1996, and the Taxpayer Relief Act of 1997, and certain provisions of the
Economic Growth and Tax Relief Reconciliation Act of 2001 ("EGTRRA"). This
amended Plan is intended as god faith compliance with the requirements of EGTRRA
and is to be construed in accordance with EGTRRA and guidance issued thereunder.
Except as otherwise provided, the provisions effectuating EGTRRA will be
effective beginning January 1, 2002. The EGTRRA amendments supersede the
provisions of the Plan to the extent those provisions are inconsistent with the
provisions of the EGTRRA amendments.

     Additionally, the Plan document serves as the official plan document for
the Consolidated Edison Company of New York, Inc. Tax Reduction Act Stock
Ownership Plan ("TRASOP"). The TRASOP is a plan separate from the Plan. CECONY
has entered into a separate trust agreement with Vanguard Financing Trust
Company under the TRASOP. Participation in the TRASOP is frozen.

     The Plan is amended to take into account the changes made by the collective
bargaining agreement covering employees who are members of Local 1-2 of the
Utility Workers Union of America, AFL-CIO, as effective June 24, 2000, Local 3
of the International Brotherhood of Electrical Workers, AFL-CIO, as effective
June 24, 2001, and

                                                                               3
<Page>

the collective bargaining agreement for Local 503 of the International
Brotherhood of Electrical Workers, AFL-CIO, as effective June 20, 2000.

     Except as otherwise specifically provided herein, the rights and benefits
of any Participant who retires or whose employment is terminated are determined
in accordance with the provisions of the Plan as in effect and operative at the
time of such retirement or termination.

     Effective May 8, 2002, the Company amended the Plan to incorporate, as a
separate part, an employee stock ownership plan ("ESOP"). All Participants are
eligible to participate in the ESOP. Any Participant who elects as an Investment
Fund, the Company Stock Fund for his or her Employer Contributions, will be
deemed to be an ESOP Participant. Only Employer Contributions will be
contributed to the ESOP.

                                                                               4

on whose behalf no Pre-Tax Contributions are made. The Actual Deferral
Percentage of each Eligible Employee shall be rounded to the

Eligible Employee in the Plan Year but for the deferral election, or are
attributable to services performed by the Eligible Employee in the Plan Year and
would have been received by the Eligible Employee within 2 1/2 months after the
close of the Plan Year but for the deferral election;

     (b) are allocated to the Eligible Employee as of a date within that Plan
Year and the allocation is not contingent on the participation or performance of
service after such date; and (c) are actually paid to the Trustee no later than
12 months after the end of the Plan Year to which the contributions relate.

from 1994 to 2001 the Cost-of-Living Adjustment is equal to or greater than
$10,000, then the Annual Dollar Limit for any Plan Year beginning January 1,
1995, shall be increased by the amount of such Cost-of-Living Adjustment,
rounded to the next lowest multiple of $10,000. Effective January 1, 2002, the

to make Pre-Tax Contributions or After-Tax Contributions for a Payroll Period an
amount equal to 50% of the aggregate Participating Contributions made by the
CECONY Weekly Participant for such Payroll Period matching first Pre-Tax
Contributions and then After-Tax Contributions. Employer Contributions are made
expressly conditional on the Plan satisfying the provisions of Article VIII. If
any portion of the Pre-Tax Contribution or After-Tax Contribution to which the
Employer Contribution relates is returned to the CECONY Weekly Participant under
Section 3.01, 8.01, 8.02 or 8.03, the corresponding Employer Contribution will
be forfeited, and if any amount of the Employer Contribution is deemed an Excess

Contributions made on behalf of or by the CECONY Management Participant or the
CEI Participant to the Plan during each month, not to exceed 6% of Compensation
for such month, to be matched first on Pre-Tax Contributions, and then on
After-Tax Contributions. Employer Contributions for a month will not exceed 3%
of the Participant's Compensation for such month. Employer Contributions are
made expressly conditional on the Plan satisfying the provisions of Article
VIII. If any portion of the Pre-Tax Contribution or After-Tax Contribution to
which an Employer Contribution relates is returned to the CECONY Management
Participant or CEI Participant under Section 3.01, 8.01, 8.02 or 8.03, the
corresponding Employer Contribution will be forfeited, and if any amount of the
Employer Contribution is deemed an Excess Aggregate Contribution under Section
8.03, the Excess Aggregate Contribution will be forfeited in accordance with the
provisions of Section 8.03. In the event a CECONY Management Participant or CEI
Participant elects to make Pre-Tax Contributions and/or After-Tax Contributions
in an amount which, when taking into account his or her Employer Contributions,
exceeds the maximum annual additions, as defined and determined in Section 8.03
of the Plan, the Employer will contribute an additional Employer contribution on
behalf of such Participant ("CECONY/CEI True- Up Contribution"). The CECONY/CEI
True- Up Contribution, will be made as soon as administratively possible after
the end of the Plan Year, for each such CECONY Management Participant and CEI
Participant who is employed at year end. The CECONY/CEI True-Up Contribution
will equal the difference between 3% of such Participant's Compensation on an
annual basis minus his or her total Employer Contributions made during the year.

     (c)    O&R HOURLY PARTICIPANT O&R will contribute on behalf of each O&R
Hourly Participant who elects to make Pre-Tax Contributions an amount equal to

O&R Hourly Participant during each month, where beginning: (1) January 1, 2000,
"x" equals 3; (2) January 1, 2003, "x" equals 4; and (3) January 1, 2004, "x"
equals 5 of the O&R Hourly Participant's Compensation for such month. In
addition, as soon as administratively possible after the end of the Plan Year,
O&R will contribute, as of the end of the Plan Year, for each O&R Hourly
Participant who is employed at year end and who in the prior Payroll Periods

beginning (1) January 1, 2000, 3%; (2) January 1, 2003, 4%; or (3) January 1,
2004, 5%; of the O&R Hourly Participant's Compensation, an Employer Contribution
equal to 50% of the O&R Hourly Participant's Pre-Tax Contributions that were not
previously matched ("True-Up Contributions"). True-Up Contributions will not
exceed such amount as will result in the total O&R Employer Contributions, both
those made previously during the year and those as of year end, exceeding 50% of
a O&R Hourly Participant's Pre-Tax Contributions that do not exceed, beginning:
(1) January 1, 2000, 3%; (2) January 1, 2003, 4%; or (3) January 1, 2004, 5%, of

of year end, exceeding 50% of a O&R Management Participant's Pre-Tax
Contributions that do not exceed 3% of his or her Compensation on an annual
basis.

     3.06   ROLLOVER CONTRIBUTIONS

     (a)    Subject to such terms and conditions as the Plan Administrator may
determine to be appropriate, applied in a uniform and non-discriminatory manner
to all Eligible Employees, and without regard to any limitations on
contributions set forth in this Article 3, the Plan may receive from an Eligible
Employee for credit to his or her Rollover Contributions Subaccount, in cash,
any amount previously distributed (or deemed to have been distributed) to him or
her from a qualified plan or, beginning January 1, 2002, a traditional
individual retirement account ("IRA"), a government plan subject to Code Section
457 or a Code Section 403(b) tax sheltered annuity. The Plan may receive such
amount either from the Eligible Employee or in the form of a direct rollover.
Notwithstanding the foregoing, the Plan shall not accept any amount unless such
amount is eligible to be rolled over in accordance with applicable law and the
Eligible Employee provides evidence satisfactory to the Plan Administrator that
such amount qualifies for rollover treatment. Unless received by the Plan in the
form of a direct rollover, the rollover contribution must be paid to the Trustee
on or before the 60th day after the day it was received by the Eligible Employee
or be rolled over from an IRA. Effective January 1, 2002, an eligible rollover
distribution from an IRA is the amount of a distribution from an IRA that is
includible in gross income, including amounts attributable to an Employee's
personal IRA contributions made outside of a qualified plan. At the time
received by the Plan, the Eligible Employee

                                                                              35
<Page>

shall, in such manner and on such conditions as may be prescribed by the Plan
Administrator, elect to invest the Rollover Contribution in the investment funds
then available under the Plan to a Participant. If the Eligible Employee fails
to make an investment election, 100% of the Rollover Contribution shall be
invested in the Fixed Income Fund.

     (b)    The Plan may also accept from a former Employee who is a Participant
a rollover or a direct rollover of an amount received from a defined benefit
plan sponsored by an Employer or from the TRASOP.

     (c)    Subject to terms and conditions as the Plan Administrator may
determine to be appropriate, applied and non-discriminatory manner to all
Participants, the Plan may receive on behalf of Participant a trust-to-trust
transfer from another qualified plan. Any Participant whose benefits are the
subject of a trust-to-trust transfer from another qualified plan to this Plan
will be entitled to receive benefits, rights and features from the Plan that are
no less than the benefits, rights and features he would be entitled to receive
from the other qualified plan immediately preceding the transfer. To the extent
feasible, such transfer shall be made on an in-kind basis. To the extent such
transfer is made in the form of cash, at the time received by the Plan the
Participant shall, in such manner and on such terms as may be prescribed by the
Plan Administrator, elect to invest the cash in the Investment Funds then
available under the Plan other than the Company Stock fund.

     3.07   CHANGES IN CONTRIBUTIONS

     A Participant may increase, reduce, suspend or resume his or her
contributions within the limits prescribed by Sections 3.01 and/or 3.02,

before the date set by the Plan Administrator, in such manner and on such
conditions as may be prescribed by the Plan Administrator. A Participant may
make changes in contribution levels once a month.

                                                                              36

     5.01   TRUST AGREEMENT

     Contributions are held in a Trust Fund by the Trustee under a written trust
agreement between CECONY and the Trustee. TRASOP Accounts are held in a TRASOP
Trust Fund under a written trust agreement between CECONY and the Trustee. ESOP
Accounts are held in the ESOP Trust Fund which is included in, but a separate

as if fully set forth herein.

     5.02   INVESTMENT OF TRUST FUND

     (a)    The Trust Fund shall be invested and reinvested in Investment Funds
in accordance with the Participant's investment directions. The Plan is intended
to be an ERISA Section 404(c) plan within the meaning of regulations issued
pursuant to such section. Each Participant shall have the opportunity, on a
daily basis, to give investment instructions to the Trustee, or other fiduciary
who is appointed and assumes such fiduciary responsibility, with an opportunity
to obtain written confirmation of such instructions as to his or her existing
Account Balance among the Investment Funds. The Plan Administrator, the Trustee
and the Record keeper or their delegate, will comply with such instructions
except as otherwise provided in the ERISA Section 404(c) regulations. The Plan
Administrator will prescribe the form and manner in which such directions will
be made, as well as the frequency with which such directions may be made or
changed, and the dates as of which they will be effective, in a manner
consistent with the foregoing. Transfers to or

                                                                              41

Investment Fund or by the terms of the Trust Agreement.

     (b)    The Named Fiduciaries shall select a range of Investment Funds as
described by ERISA Section 404(c) and applicable regulations. The Investment
Fund categories shall give each Participant a reasonable opportunity to:

            (i)   Materially  affect the potential  return on and the degree
                  of  risk  of  assets  over  which  the  Participant  exercises
                  investment control;

            (ii)  Choose from at least three investment alternatives,  each
                  of which is diversified and has materially  different risk and
                  return characteristics;

            (iii) Enable a  Participant  to achieve a portfolio  with risk
                  and  return  characteristics  at any  point  within  the range
                  normally  appropriate by choosing among the core alternatives;
                  and

            (iv)  Diversify investments so as to minimize the risk of large
                  losses.

     (c)    The Named Fiduciaries may establish new Investment Funds without the
necessity of an amendment to the Plan and shall have the objectives prescribed
by the Named Fiduciaries. The Named Fiduciaries may eliminate one or more
Investment Fund existing at any time without the necessity of an amendment to
the Plan. The Named Fiduciaries may establish rules and procedures governing the
transfer of portions of Participant's Account Balance in the event that existing
Investment Funds are changed or new Investment Funds added. The Named
Fiduciaries may appoint an Investment Manager to manage an Investment Fund.

the Trustee for which voting directions are given by Participants.

                                                                              43

each Participant, and within each such Account Balance, as applicable, a Pre-Tax
Contributions Subaccount, an After-Tax Contributions Subaccount, a Rollover
Contributions Subaccount, an ESOP Account and an Employer Contributions

Pre-Tax Contributions Subaccount, After-Tax Contributions Subaccount, Rollover
Contributions Subaccount, Employer Contributions Subaccount and TRASOP Account,

Administrator may direct the Recordkeeper from time to time to issue
comparable statements to Participants as of other dates during the calendar
year.

     5.06   RESPONSIBILITY FOR INVESTMENT

     Each Participant is solely responsible for the selection of his or her
Investment Funds. The Trustee, the Recordkeeper, any Investment Manager, the
Named Fiduciaries, the Plan Administrator, the Company, each Employer and the
trustees, officers and other Employees of each entity are not empowered to
advise a Participant as to the decision in which his or her Account Balance is
invested. The fact that an Investment Fund is available to Participants for
investment under the Plan is not to be construed as a recommendation for a
particular Participant to invest in the Investment Fund.

                                                                              45

<Page>

A Participant may apply for a hardship withdrawal in such manner and on
such conditions as may be prescribed by the Plan Administrator. A Participant
shall be deemed to have a hardship if the Participant has an immediate and heavy
financial need and if the withdrawal is necessary to satisfy such financial need
as set forth below. The Plan Administrator or his or her delegate shall
determine whether the Participant satisfies the requirements for a hardship and
the amount of any hardship withdrawal. Any withdrawal under this Section shall
be made pro-rata from the Participant's balances in the Investment Funds from
which withdrawal may be made as provided in Section 7.03. A withdrawal pursuant
to this Section 7.04 shall not be subject to the limitations on number of
withdrawals permitted under Section 7.03.

     (a)    IMMEDIATE AND HEAVY FINANCIAL NEED. A Participant will be deemed to
have an immediate and heavy financial need if the withdrawal is to made on
account of any of the following:

       (1)  Medical expenses described in Code Section 213(d) previously
            incurred by the Participant, the Participant's spouse or any
            dependent, (as defined in Code Section 152), of the Participant, or
            expenses necessary for those persons to obtain medical care
            described in Code Section 213(d);

       (2)  Costs directly related to the purchase, excluding mortgage payments,
            of a principal residence for the Participant;

       (3)  Payment of tuition, related educational fees, and room and board
            expenses for the next twelve-months of post- secondary education for
            the Participant, or the Participant's spouse, children or
            dependents;

                                                                              57
<Page>

       (4)  Payment of amounts necessary to prevent the eviction of the
            Participant from his or her principal residence or to avoid
            foreclosure on the mortgage of the Participant's principal
            residence;

       (5)  Payment of funeral expenses for a family member;

       (6)  Any other need added to the foregoing items of deemed immediate and
            heavy financial needs by the Commissioner of the Internal Revenue
            Service through the publication of revenue rulings, notices and
            other documents of general availability, rather than on an
            individual basis.

       (7)  A Participant shall not be permitted to make a withdrawal in the
            event of a hardship on account of any reason other than as set forth
            above.

     (b)    NECESSARY TO SATISFY SUCH NEED. The requested withdrawal will not
be treated as necessary to satisfy the Participant's immediate and heavy
financial need to the extent that the amount of the requested withdrawal is in
excess of the amount required to relieve the financial need or to the extent
such need may be satisfied from other sources that are reasonably available to
the Participant. The amount of an immediate and heavy financial need may include
any amounts necessary to pay any federal, state or local income taxes or
penalties reasonably anticipated to result from the hardship withdrawal. The
Participant must request, on such form or otherwise as the Plan Administrator or
his or her delegate may prescribe, that the Plan Administrator or his or her
delegate made its determination of the necessity for the withdrawal solely on
the basis of the Participant/s certification, without any supporting documents.
In the event the Plan Administrator or his or her delegate shall make such
determination provided all of the following requirements are met: (1) the
Participant has obtained all distributions and withdrawals, other than
distributions available only on account

                                                                              58
<Page>

of hardship, and all nontaxable loans currently available under all plans of the
Company and Affiliates, (2) the Participant is prohibited from making Pre-Tax
Contributions and After-Tax Contributions to the Plan and all other plans of the
Company and Affiliates under the terms of such plans or by means of an otherwise
legally enforceable agreement for at least 12 months, or beginning on or after
January 1, 2002, six months, after receipt of the distribution, and (3) the
limitation described in Section 3.02 under all plans of the Company and
Affiliates for the calendar year following the year in which the distribution is
made must be reduced by the Participant's Pre-Tax Contributions made prior to
such distribution in the calendar year of the distribution for hardship. All
other plans of the Company and Affiliates means all qualified and non-qualified
plans of deferred compensation maintained by the Company and Affiliates and
includes a stock option, stock purchase (including the Company's Discount Stock
Purchase Plan), qualified and non-qualified deferred compensation plans and such
other plans as may be designated under regulations issued under Code Section
401(k), but shall not include health and welfare benefit plans.

     Where an amount to be distributed pursuant to Section 7.02, 7.03 or 14.10
is represented in part by Units, the distributee may elect, in such manner and
on such conditions as may be prescribed by the Plan Administrator, to have
distributed the number of whole Shares represented by such Units, together with
an amount of dollars representing the balance of the current value of such
Units. In the absence of such an election, the distribution shall be made
entirely in cash. Withdrawals for hardships or loans to be made from the Company
Stock Fund shall be made entirely in cash.

     7.06   LEAVES OF ABSENCE

                                                                              59

     If a Participant is granted an unpaid leave of absence by an Employer, such
event will not be deemed a termination of service, but such Participant's
Pre-Tax Contributions and After-Tax Contributions under this Plan will be
suspended as of the last day of the Payroll Period in which such leave
commences. Such Participant may resume making Pre-Tax Contributions and
After-Tax Contributions, as of a Payroll Period following the termination of
such leave of absence, by making a new payroll deduction authorization in such
manner and on such conditions as may be prescribed by the Plan Administrator.
Notwithstanding the preceding sentence, and the provisions of Section 7.04, if a
Participant makes a hardship withdrawal while on a leave of absence, any
suspension of such Participant's right to make Pre-Tax or After-Tax
Contributions which shall result from such withdrawal shall begin with the first
Payroll Period beginning after such leave of absence.

     7.07   AGE 70 1/2 REQUIRED DISTRIBUTION

     (a)    A Participant who attains age 70 1/2 on or after January 1, 2000,
shall begin his or her distribution of his or her Account Balance no later than
the April 1st following the later of the calendar year in which he or she
attains age 70 1/2 or the calendar year in which the Participant terminates
employment.

     (b)    In the event a Participant in active service was required prior to
January 1, 2000 to begin receiving payments while in service under the
provisions of a Prior Plan, the Plan shall distribute to the Participant in each
distribution calendar year the minimum amount required to satisfy the provisions
of Code Section 401(a)(9) provided; however, that the payment for the first
distribution calendar year shall be made on or before April 1 of the following
calendar year. Such minimum amount will be determined on the basis of the joint
life expectancy of the Participant and his or her Beneficiary. Such life
expectancy will be recalculated once each year; however, the life expectancy of
the Beneficiary will not be

                                                                              60
<Page>

recalculated if the Beneficiary is not the Participant's spouse. The amount of
the withdrawal shall be allocated among the Investment Funds in proportion to
the value of the Account Balance as of the date of each withdrawal. The
commencement of payments under this Section shall not constitute an Annuity
Starting Date for purposes of Code Sections 72, 401(a)(11) and 417. Upon the
Participant's subsequent termination of employment, payment of the Participant's
Account Balance shall be made in accordance with the provisions of Section 7.08.

     (c)    With respect to distributions under the Plan made in calendar years
beginning on or after January 1, 2000, the Plan will apply the minimum
distribution requirements of Code Section 401(a)(9) that were proposed in
January 2001, notwithstanding any provision of the Plan to the contrary. This
amendment shall continue in effect until the end of the last calendar year
beginning before the effective date of final regulations under Code Section
401(a)(9) or such other date specified in guidance published by the Internal
Revenue Service.

     7.08   FORM AND TIMING OF DISTRIBUTIONS

     (a)    TIMING OF DISTRIBUTIONS. Upon termination from employment with the
Company and any Affiliate service, distributions will be made as follows:

       (1)  if the vested portion of the Participant's Account Balance equals
            $5000 or less, his or her Account Balance will be distributed in a
            single lump sum as soon as practicable but not later than 60 days
            after the end of the calendar year in which the Participant's
            termination from employment occurs; or

       (2)  unless the Participant consents to a distribution upon termination
            from employment, if the vested portion of the Participant's Account
            Balance exceeds $5000, distribution will be deferred until April 1
            of the calendar year

                                                                              61
<Page>

            following the calendar year in which the Participant attains age 70
            1/2 unless, and until, the Participant elects an earlier
            distribution under Section 7.08(b).

       (3)  Termination of employment entitling a Participant to a distribution
            does not occur in the event of a corporate transaction in which
            there is a transfer of the Account Balances of Participants affected
            by the corporate transaction to a plan maintained or created by the
            affected Participant's new employer.

     (b)    The Participant may elect an immediate or deferred distribution,
subject to Code Section 401 (a)(9), Article XIV, if applicable, and, in such
manner and on such conditions as may be prescribed by the Plan Administrator,
any of the following:

       (1)  a distribution of the Participant's Vested Account Balance in a
            single lump sum;

       (2)  monthly, quarterly or annual periodic installment payments in a
            fixed dollar amount or fixed percentage amount, up to a 15-year
            period; or

       (3)  a distribution of all or part of the Participant's Vested Account
            Balance.

     (c)    If a Participant's distribution is deferred until April 1 of the
calendar year following the calendar year in which the Participant attains again
70 1/2, the Participant may elect, in such manner and on such condition s as may
be presented by the Plan administrator;

       (1)  a distribution in a single lump sum, or

       (2)  a distribution in the required minimum amounts and over the
            applicable distribution period prescribed under the Code's minimum
            distribution rules. If the Participant fails to make an election,
            the distribution shall be made in a single lump sum;

                                                                              62
<Page>

     (d)    Any distribution of less than all of a Participant's Vested Account
Balance shall be made pro-rata from the Investment Funds in which the Account
Balance in invested.

     7.09   PROOF OF DEATH AND RIGHT OF BENEFICIARY OR OTHER PERSON

     The Plan Administrator may require and rely upon such proof of death and
such evidence of the right of any Beneficiary or other person to receive the
value of the vested Account Balance of a deceased Participant as the Plan
Administrator may deem proper, and his or her determination of the right of that
Beneficiary or other person to receive payment will be conclusive.

     7.10   DISTRIBUTION LIMITATION

     Notwithstanding any other provision of this Article 7, all distributions
from this Plan shall conform to the regulations issued under Code Section
401(a)(9), including the incidental death benefit provisions of Code Section
401(a)(9)(G). Such regulations override any Plan provision that is inconsistent
with Code Section 401(a)(9).

     7.11   DIRECT ROLLOVER OF CERTAIN DISTRIBUTIONS

     Notwithstanding any provision of the Plan to the contrary that would
otherwise limit a Distributee's election under this Section, a Distributee may
elect, in such manner and on such conditions as may be prescribed by the Plan
Administrator, to have any portion of an Eligible Rollover Distribution paid
directly to an Eligible Retirement Plan specified by the Distributee in a direct
rollover. The following definitions apply to the terms used in this Section:

     (a)    ELIGIBLE ROLLOVER DISTRIBUTION means any distribution of all or any
portion of the balance to the credit of the Distributee. An Eligible Rollover
Distribution does not include any distribution that is one of a series of
substantially equal periodic payments (not less frequently than annually) made
for the life (or life expectancy) of the Distributee or the

                                                                              63
<Page>

joint lives (or joint life expectancies) of the Distributee and the
Distributee's designated beneficiary, or for a specified period of ten years or
more or any distribution to the extent such distribution is required under Code
Section 401(a)(9). Any amount that is distributed on account of hardship is not
an Eligible Rollover Distribution. The Distributee may not elect to have any
portion of a hardship distribution paid directly to an Eligible Retirement Plan.
Effective beginning January 1, 2002, a distribution does not fail to be an
Eligible Rollover Distribution solely because it includes after-tax employee
contributions that are not includible in gross income. The portion attributable
to after-tax contributions may be transferred only to an individual retirement
account or annuity described in Code Section 408(a) or (b), or to a qualified
defined contribution plan described in Code Section 401(a) or 403(a) that agrees
to separately account for amounts so transferred, including separately
accounting for the portion of such distribution which is includible in gross
income and the portion of such distribution which is not so includible.

     (b)    ELIGIBLE RETIREMENT PLAN means an individual retirement account
described in Code Section 408(a), an individual retirement annuity described in
Code Section 408(b), an annuity plan described in Code Section 403(a), or a
qualified trust described in Code Section 401(a) that is a defined contribution
plan, that accepts the Distributee's Eligible Rollover Distribution. However, in
the case of an Eligible Rollover Distribution to the surviving spouse, an
Eligible Retirement Plan is an individual retirement account or individual
retirement annuity. Effective January 1, 2002, Eligible Retirement Plan also
means an annuity plan described in Code Section 403(b), and an eligible plan
under Code Section 457(b) maintained by a political subdivision of a state, or
any agency or instrumentality of a state or political subdivision of a state and
which agrees to separately

                                                                              64
<Page>

account for amounts transferred into such plan from this Plan, including
separately accounting for the portion of such distribution that is includible in
gross income and the portion of such distribution that is not so includible.

     (c)    DISTRIBUTEE means an Employee, former employee, the surviving
spouse of the Employee or Former Employee, spouse or former spouse of an
Employee or Former Employee who is the alternate payee under a qualified
domestic relations order as defined in Code Section 414(p), are Distributees.

     (d)    DIRECT ROLLOVER means a payment by the Plan to the Eligible
Retirement Plan specified by the Distributee.

                                                                              65

                                  ARTICLE VIII

                        NON-DISCRIMINATION AND LIMITATION

     8.01   ACTUAL DEFERRAL PERCENTAGE TEST

     (a)    Separate Testing Groups. Solely for purposes of determining whether
the Plan satisfies the Average Actual Deferral Percentage tests, the Plan will
be tested as if it were four separate plans ("Testing Plan"): (1) a Plan
covering CECONY Management Employees, O&R Management Employees and CEI Employees
("Management Employees"), (2) a Testing Plan covering O&R Hourly
Employees("O&RU"), (3) a plan covering Local 1-2 Employees ("Local 1-2U") and,
(4) a plan covering Local 3 Employees ("Local 3U"). Each employee in the O&RU,
Local 1-2U, and Local 3U is referred to as a "Union Employee." Solely for
purposes of determining whether a Testing Plan satisfies the Actual Deferral
Percentage Test, an Employee who is under age 21 or has less than one Year of
Service is not taken into account as an Eligible Employee.

     (b)    The Average Actual Deferral Percentage for both Highly Compensated
Management Employees ("HCMEs") and for Highly Compensated Union Employees
("HCUEs"), respectively, who are, or are eligible to become, Participants may
not exceed the greater of:

            (i)   the Average Actual Deferral Percentage for Non-Highly
                  Compensated Management Employees ("NHCMEs") or Non-Highly
                  Compensation Union Employees ("NHCUEs"), respectively, who
                  are, or eligible to become, Participants multiplied by 1.25;
                  or

            (ii)  the Average Actual Deferral Percentage for HCMEs or HCUEs,
                  respectively, multiplied by 2.0, but not more than 2
                  percentage points in

                                                                              66
<Page>

                  excess of the Average Actual Deferral Percentage for the
                  NHCMEs or NHCUEs, respectively.

     (c)    During a Plan Year, the Plan Administrator may implement rules
limiting the Pre-Tax Contributions which may be made on behalf of some or all of
either the HCMEs or HCUEs so that this limitation is satisfied. If the Plan
Administrator determines that the limitation has been exceeded in any Plan Year,
the following provisions apply:

       (1)  The amount of Pre-Tax Contributions made by either the HCMEs or
            HCUEs, as applicable, will be reduced by a leveling process under
            which the Pre-Tax Contributions of the HCME or HCUE, as applicable,
            with the highest dollar amount of Pre-Tax Contributions shall be
            reduced to the extent necessary to completely eliminate the excess
            Pre-Tax Contribution or cause such Pre-Tax Contributions to equal
            the amount of such contributions of the HCME or HCUE, as applicable,
            with the next highest dollar amount of Pre-Tax Contribution. This
            process will be repeated until the excess Pre-Tax Contribution is
            eliminated.

       (2)  Excess Pre-Tax Contributions, together with Earnings, will be paid
            to the Participant before the close of the Plan Year following the
            Plan Year in which the excess Pre-Tax Contributions were made and,
            to the extent practicable, within 21/2months of the close of the
            Plan Year in which the Excess Pre-Tax Contributions were made.
            However, any Excess Pre-Tax Contributions for any Plan Year will be
            reduced by any Pre-Tax Contributions previously returned to the
            Participant for that Plan Year. If any returned Excess Pre-Tax
            Contributions were matched by Employer Contributions, such
            corresponding

                                                                              67
<Page>

            Employer Contributions, with Earnings will be forfeited and used to
            reduce Employer Contributions. The Participant, other than an O&R
            HCUE, may elect, in lieu of a return of the Excess Pre-Tax
            Contributions to have the Plan treat all or a portion of the Excess
            Pre-Tax Contributions to the Plan as After-Tax Contributions for the
            Plan Year in which the Excess Pre-Tax Contributions were made,
            subject to the limitations of Section 3.01. Re-characterized Excess
            Pre-Tax Contributions shall be considered After-Tax Contributions
            made in the Plan Year to which the Excess Pre-Tax Contributions
            relate for purposes of Section 8.02 and shall be subject to the
            withdrawal provisions applicable to After-Tax Contributions under
            Article 7. The Participant's election to re-characterize Excess
            Pre-Tax Contributions shall be made within 2 1/2 months of the close
            of the Plan Year in which the Excess Pre-Tax Contributions were made
            or within such shorter period as the Plan Administrator may
            prescribe. In the absence of a timely election by the Participant,
            the Plan shall return Excess Pre-Tax Contributions.

     8.02   ACTUAL CONTRIBUTION PERCENTAGE TEST

     (a)    Solely for purposes of determining whether the Plan satisfies the
Average Contribution Percentage test, the Plan will not test Union Employees.
The Plan will test only the Management Employees.

     (b)    The Average Contribution Percentage for HCMEs who are, or eligible
to become, Participants may not exceed the Average Contribution Percentage of
NHCMEs who are, or are eligible to become, Participants multiplied by 1.25. If
the Average Contribution Percentage for the HCMEs does not meet the foregoing
test, the Average Contribution Percentage for HCMEs may not exceed the Average
Actual Contribution Percentage of

                                                                              68
<Page>

NHCMEs who are, or eligible to become, Participants by more than two percentage
points, and the Average Contribution Percentage for HCMEs may not be more than
2.0 times the Average Contribution Percentage for NHCMEs (or such lesser amount
as the Plan Administrator shall determine to satisfy the provisions of Section
8.03). During a Plan Year, the Plan Administrator may implement rules limiting
the After-Tax Contributions which may be made by some or all HCMEs so that this
limitation is satisfied. If the Plan Administrator determines that the
limitation under this Section 8.02 has been exceeded in any Plan Year, the
following provisions shall apply:

       (1)  The amount of After-Tax Contributions and Employer Contributions
            made by or on behalf of some or all HCMEs in the Plan Year shall be
            reduced in the same leveling manner as Excess Pre-Tax Contributions
            are reduced.

       (2)  Any Excess Aggregate Contributions will be reduced and allocated in
            the following order:

            (i)   Non-Participating After-Tax Contributions, to the extent of
                  the Excess Aggregate Contributions, will be paid to the
                  Participant; and then, if necessary,

            (ii)  so much of the Participating After-Tax Contributions and
                  corresponding Employer Contributions, as is necessary to meet
                  the test will be reduced, with the After-Tax Contributions,
                  together with Earnings, being paid to the Participant and the
                  Employer Contributions, together with Earnings, being reduced,
                  with vested Employer Contributions being paid to the
                  Participant and Employer Contributions which are forfeitable
                  under the

                                                                              69
<Page>

                  Plan being forfeited and applied to reduce Employer
                  Contributions; then if necessary,

            (iii) so much of the Employer Contributions, together with Earnings,
                  as is necessary to equal the balance of the Excess Aggregate
                  Contributions will be reduced, with vested Employer
                  Contributions being paid to the Participant and Employer
                  Contributions which are forfeitable under the Plan being
                  forfeited and applied to reduce Employer Contributions.

     (c)    Any repayment or forfeiture of Excess Aggregate Contributions will
be made before the close of the Plan Year following the Plan Year for which the
Excess Aggregate Contributions were made and, to the extent practicable, any
repayments or forfeiture will be made within 2 1/2 months of the close of the
Plan Year in which the Excess Aggregate Contributions were made.

     8.03   SEPARATE NON-DISCRIMINATION TESTING

     Effective for Plan Years beginning on and after January 1, 2002, solely for
purposes of determining whether the Thrift Plan and the ESOP satisfy the Average
Actual Deferral Percentage Test and the Average Contribution Percentage all
Employer Contributions allocated to the Company Stock Fund are treated as
contributions to the ESOP and tested separately.

     8.04   MAXIMUM ANNUAL ADDITIONS

     (a)    Except to the extent permitting Catch-Up Contributions in accordance
with Code Section 414(v), the annual addition to a Participant's Account Balance
for any Plan Year, (the "Limitation Year") when added to the Participant's
annual addition for the Limitation Year under any other qualified defined
contribution plan of the Company or an Affiliate, may not exceed the lesser of
(1) 25% or, for Plan Years beginning on January 1, 2002,

                                                                              70
<Page>

100%, of his or her Compensation for the Plan Year or (2) the greater of $30,000
or, for Plan Years beginning on January 1, 2002, $40,000, as adjusted for
increases in the Cost-Of-Living Adjustment.

     (b)    For purposes of this Section, the annual addition to a
Participant's Account Balance under this Plan or any other qualified defined
contribution plan maintained by the Company or an Affiliate will be the sum of:

       (1)  the total contributions, including Pre-Tax Contributions, made on
            the Participant's behalf by each Employer and all Affiliates,

       (2)  all After-Tax Contributions, exclusive of any Rollover
            Contributions,

       (3)  all Employer Contributions; and

       (4)  forfeitures, if applicable, that have been allocated to the
            Participant's Account Balance under this Plan or his or her accounts
            under any other such qualified defined contribution plan. Any
            Pre-Tax Contributions distributed under Section 8.01 and any
            Employer Contributions or After-Tax Contributions distributed or
            forfeited under the provisions of Section 3.01, 8.01, 8.02 or 8.03
            shall be included in the annual addition for the year allocated.

     (c)    If the annual addition to a Participant's Account Balance for any
Plan Year, prior to the application of the limitation set forth in paragraph (a)
above, exceeds that limitation due to a reasonable error in estimating a
Participant's Compensation or in determining the amount of Pre-Tax Contributions
that may be made with respect to a Participant under Code Section 415, or as the
result of the allocation of forfeitures, the amount of contributions credited to
the Participant's Account Balance in that Plan Year shall

                                                                              71
<Page>

be adjusted to the extent necessary to satisfy that limitation in accordance
with the following order of priority:

       (1)  The Participant's Non-Participating After-Tax Contributions shall be
            reduced to the extent necessary. The amount of the reduction shall
            be returned to the Participant, together with any earnings on the
            contributions to be returned.

       (2)  The Participant's Non-Participating Pre-Tax Contributions shall be
            reduced to the extent necessary. The amount of the reduction shall
            be returned to the Participant, together with any earnings on the
            contributions to be returned.

       (3)  The Participant's Participating After-Tax Contributions and
            corresponding Employer Contributions shall be reduced to the extent
            necessary. The amount of the reduction attributable to the
            Participant's Participating After-Tax Contributions shall be
            returned to the Participant, together with any earnings on those
            contributions to be returned, and the amount attributable to the
            Employer Contributions shall be forfeited and used to reduce
            subsequent contributions payable by the affected Employer.

       (4)  The Participant's Participating Pre-Tax Contributions and
            corresponding Employer Contributions shall be reduced to the extent
            necessary. The amount of the reduction attributable to the
            Participant's Participating Pre-Tax Contributions shall be returned
            to the Participant, together with any earnings on those
            contributions to be returned, and the amount attributable to the
            Employer Contributions shall be forfeited and used to reduce
            subsequent contributions payable by the affected Employer.

                                                                              72

     (d)    Any Pre-Tax Contributions returned to a Participant under this
paragraph (d) shall be disregarded in applying the dollar limitation of Pre-Tax
Contributions under Section 3.01(b), and in performing the Actual Deferral
Percentage Test under Section 8.01. Any After-Tax Contributions returned shall
be disregarded in performing the Actual Contribution Percentage Test under
Section 8.02.

                                                                              73

                                   ARTICLE IX

                                      LOANS

     9.01   LOANS PERMITTED

     Upon terms and conditions set forth in this Article 9, and in accordance
with such uniform rules as the Plan Administrator may adopt, a Participant who
is not on a leave of absence and remains on the active payroll may borrow from
his or her Account Balance. The Plan Administrator or his or her delegate is
authorized to administer the loan program under this Article 9. Any Participant
who is an Employee, a former Employee, or a Beneficiary of an O&R Participant,
and who is also a "party-in-interest" (as defined in Section 3(14) of ERISA) to
the Plan, may borrow from his or her Account Balance.

     9.02   AMOUNT OF LOANS

     The minimum amount of any loan is $1,000 for a CECONY or CEI Participant
and $500 for an O&R Participant. Effective January 1, 2002, the minimum amount
of a loan for a CECONY or CEI Participant will be $500. The amount of any loan
to a Participant may not exceed the lesser of (a) or (b), where (a) is $50,000
reduced by the excess (if any) of (i) the highest outstanding balance of loans
to the Participant from the Plan during the one-year period ending on the day
before the date on which such loan is made, over (ii) the outstanding balance of
loans to the Participant from the Plan on the date on which such loan is made,
and (b) is one-half of the vested portion of the Participant's Account Balance.
Outstanding balance of loans means the outstanding amount of all loans from the
Plan and any other qualified plans of the Company or an Affiliate.

     9.03   SOURCE OF LOANS

                                                                              74
<Page>

     (a)    Funds for loans from a Participant's Account Balance shall be taken
from the Participant's Subaccounts in the following order:

       (1)  For a CECONY Participant:

            (i)   Non-Participating Pre-Tax Contributions and Earnings;

            (ii)  Participating Pre-Tax Contributions and Earnings;

            (iii) Rollover Contributions and Earnings;

            (iv)  Vested Employer Contributions and Earnings that have been in
                  the Account Balance for three full calendar years for a CECONY
                  Weekly Participant and two full calendar years for a CECONY or
                  CEI Management Participant after the contribution year and
                  Earnings;

            (v)   Non-Participating After-Tax Contributions and Earnings; and

            (vi)  Participating After-Tax Contributions and Earnings.

       (2)  For an O&R Participant:

            (i)   Pre-Tax Contributions and Earnings;

            (ii)  Rollover Contributions and Earnings; and

            (iii) After-tax Contributions and Earnings.

     (b)    No loan will be made from a Subaccount or a part of a Subaccount
until the entire balance in the Subaccount or part of the Subaccount preceding
it on the above list has been exhausted. Within each Subaccount or part thereof,
funds for loans will be taken on an average cost basis and pro-rata from each
Investment Fund within the Subaccount or part of the Subaccount, and such
pro-rata portion of each Investment Fund will be converted to cash for the loan
based upon the market value of the investment on the date of conversion.

     9.04   INTEREST RATE

                                                                              75
<Page>

     The interest rate to be charged on loans will be a reasonable rate of
interest determined from time to time by the Plan Administrator. In determining
such rate the Plan Administrator seeks to provide to the Plan a rate of return
commensurate with the interest rates charged by persons in the business of
lending money for loans that would be made under similar circumstances on the
date the loan is approved. The interest rate will be fixed for the entire term
of the loan.

     Effective for loans originating before January 1, 2001, the interest rate
to be charged to an O&R Participant is the effective interest rate charged by
the Orange and Rockland Employees' Federal Credit Union for a 48 month
share-secured loan. The interest rate to be charged for a principal residence
loan to an O&R Management Participant will be based upon Federal National
Mortgage Association mortgage rates. Effective for loans originating after
January 1, 2001, the interest rate to be charged to an O&R Participant will be
the same interest rate applicable to a CECONY Participant.

     9.05   REPAYMENT

     The Participant may select a period of one, two, three, four or five years
for repayment of a loan, except that the Participant may, at his or her option,
select a longer period of whole years, not exceeding ten, (20 in the case of an
O&R Management Participant) for repayment of a loan for the purpose of
purchasing his or her principal residence. Repayment will be made by level
payments, not less frequently than quarterly, in such amount as shall be
sufficient to pay the principal and interest thereon over the period for
repayment. Repayment shall be made by payroll deductions, except that in the
case of a Participant who is not on the active payroll, repayments may continue
to be made by check or other similar means as the Plan Administrator shall
determine. Prepayment by a CECONY Weekly Participant of a loan in full, without
penalty, may be made only after 52

                                                                              76
<Page>

weekly payments have been made. Prepayment by an O&R Participant of a loan in
full, without penalty, and prepayment by a CECONY Management or CEI Participant
of a loan in full or in part, without penalty, may be made at any time by
personal check or money order. The amount of each loan payment shall be placed
into the Investment Funds, except the Company Stock Fund, in accordance with the
most recent investment election made by the Participant with respect to the
Participant's Contributions. Notwithstanding the foregoing, a loan which is made
to a Participant who is an Employee shall become due and payable in full upon
the Employee's termination of employment; provided, however, that if a
Participant becomes an employee of a buyer or one of its affiliates following
the sale of the Company's or an Affiliate's assets, and if the Participant's
Account is transferred to a qualified plan maintained by the buyer or one of its
affiliates (the "Buyer's Plan"), any outstanding loan at his or her termination
of employment with the Company will not be due and payable in full at
termination but will instead be transferred to the Buyer's Plan.

     9.06   MULTIPLE LOANS

     A CECONY Weekly Participant may not have more than one loan outstanding at
a time. A CECONY Management or CEI Participant may not have more than one loan
granted in a calendar year unless all earlier loans made in the same calendar
year to the Participant shall have been repaid in full. An O&R Participant may
not have more than one loan outstanding at any time and may make a request for a
loan only once in a twelve month period.

     9.07   PLEDGE

     The vested portion of the Participant's Account Balance shall be pledged as
security for all loans to the Participant. The amount pledged shall not be
greater than fifty percent of the Participant's vested portion. If a default
occurs in the repayment of a loan, the entire

                                                                              77
<Page>

unpaid principal balance plus accrued interest, if any: (i) will be charged,
when the Participant becomes eligible to receive a distribution, against that
portion of the Participant's vested portion which serves as security for the
loan; (ii) will be deducted, if a distribution is to made, from the amount
payable to the Participant or the Participant's Beneficiary; or (iii) if neither
(i) nor (ii) applies, will continue to encumber that portion of the
Participant's vested portion that serves as security for the loan.

     9.08   LOAN RESERVE

     The amount of each loan to a Participant will be transferred from the
portion of the Trust Fund held for the Participant's Account Balance and
invested pursuant to Section 5.02 to a special Loan Reserve maintained for such
Participant's Account Balance. Such Loan Reserve will be invested solely in the
loan or loans made to the Participant. Payments on any such loan will reduce the
Participant's Loan Reserve and will be reinvested for the Participant's Account
Balance in accordance with Section 9.05.

     9.09   MINIMUM ACCOUNT BALANCE

     So long as any amount of a loan remains outstanding to a Participant, the
Participant may not make any withdrawal from his or her Account Balance that
would reduce the value of his or her vested portion to less than his or her Loan
Reserve.

     9.10   OTHER TERMS

     Each loan will be evidenced by a promissory note payable to the Trustee.
The terms and conditions of any loan may be adjusted at any time, to the extent
determined by the Plan Administrator, to be necessary for compliance with law or
to maintain the qualification of the Plan under the Code.

                                                                              78

     The following persons from time to time occupying the following offices of
CECONY are hereby designated as Named Fiduciaries: Chief Executive Officer,
Chief Financial Officer, and Chief Accounting Officer. CECONY may designate

Fiduciaries either instead of or in addition to those named above. Any such
designation and acceptance shall be in writing and retained by the Plan
Administrator. The Named Fiduciaries shall act by majority rule. The Named
Fiduciaries shall appoint from among the officers of CECONY a Plan Administrator
who shall serve at the discretion of the Named Fiduciaries. The Plan

     Solely in this Article X, the term Plan includes the Thrift Savings Plan,
the ESOP and the TRASOP unless the context clearly designates otherwise.

     10.02  AUTHORITY OF PLAN ADMINISTRATOR

     The Plan Administrator has the discretionary authority to control and

the generality of the foregoing, shall interpret the Plan, ESOP,, determine
eligibility for benefits under the Plan, determine any facts or resolve any
questions relevant to the administration of the Plan, ESOP, and TRASOP and, in
connection therewith, may remedy and correct any ambiguities, inconsistencies,
or omissions in the Plan, ESOP and TRASOP. Any such action taken by the

                                                                              79
<Page>

Plan Administrator shall be conclusive and binding on all Participants, ESOP
Participant, Beneficiaries and other persons. The Plan Administrator is

to the Plan, ESOP and TRASOP, which are (a) required or desirable in order to
implement corporate transactions such as mergers, acquisitions and divestitures;
(b) required, necessary or recommended for compliance with ERISA, the Code or
other laws; or (c) necessary or desirable for uniform or efficient
administration. In all cases, any amendment(s) adopted by the Plan Administrator
shall neither materially nor significantly increase the Employers' or the
Company's obligations or adversely affect or reduce the Account Balance of any
Participant.

     10.03  RELIANCE ON REPORTS

     The Named Fiduciaries and the Plan Administrator are entitled to rely upon

selling expenses incurred by the Trustee in the sale of Shares pursuant to
Article XIII, losses incurred by the Trustee on funds invested pursuant to
Article XIII, and fees of the Trustee in connection with the administration of

brokerage fees and commissions for purchases of Shares pursuant to Section
13.02, which brokerage fees and commissions shall be paid out of the dividends
being reinvested thereby. Such expenses of administration of TRASOP will, to the
extent permitted by law, be paid:

            (i)   first, out of any available income of TRASOP;

            (ii)  second, out of any available dividends received by the Trustee
                  on Shares allocated to Participants pursuant to Section 13.02,

                  additional Shares pursuant to Section 13.02; and

            (iii) Third, by CECONY.

     In no event shall the amounts paid by the Trustee during such Plan Year

dividends paid to the Trustee with respect to common stock of the Company during
such Plan Year or $100,000.

     10.06  FIDUCIARY INSURANCE

under which each member of the Board, each Named Fiduciary, the Plan
Administrator, and any person, including each employee, to whom there may be
delegated any responsibility in connection with the administration of the Plan,
including the Trustee, will be indemnified against any cost or expense
(including counsel's fees) or liability which may be incurred arising out of any
act or failure to act in the administration of this Plan, except for gross
negligence or willful misconduct.

     10.07  CLAIM REVIEW

     (a)    Upon receipt from a Participant or Beneficiary of an initial claim
for benefits, the Plan Administrator shall respond in writing and deliver or
mail to the Participant or Beneficiary within 90 days following the date on
which the initial claim is filed. If the initial claim is denied, in part or
totally, the Plan Administrator shall set forth the specific reasons for the
denial, written in a plain and understandable manner, with specific reference to
pertinent Plan, ESOP and TRASOP provisions on which the denial is based, a
description of any additional material or information necessary for the claimant
to perfect the claim, an explanation of why such material or information is
necessary, and an explanation of the Plan's ESOP and TRASOP claim review
procedure. If special circumstances require an extension of time for processing
the claim, written notice of an extension shall be furnished to the claimant
prior to the end of the initial period of 90 days following the date on which
the claim was filed. Such an extension may not exceed a period of 90 days beyond
the end of the initial period. If the claim has not been granted, and if written
notice of the denial of the

                                                                              82
<Page>

claim is not furnished within 90 days following the date on which the claim is
filed, the claim shall be deemed denied for the purpose of proceeding to the
claim review procedure.

     (b)    CLAIM REVIEW PROCEDURE. A Participant, Beneficiary, or the
authorized representative of either shall have 60 days after receipt of written
notification of denial of a claim to request a review of the denial by making
written request to the Plan Administrator. The Plan Administrator shall give the
Participant, Beneficiary, or the authorized representative of either an
opportunity to appear to review pertinent documents, to submit issues and
comments in writing, and to present evidence supporting the claim. Not later
than 60 days after receipt of the request for review, the Plan Administrator
shall render and furnish to the claimant a written decision which shall include
specific reasons for the decision, and shall make specific references to
pertinent Plan provisions on which it is based. If special circumstances require
an extension of time for processing, the decision shall be rendered as soon as
possible, but not later than 120 days after receipt of the request for review,
provided that written notice and explanation of the delay are given to the
claimant prior to commencement of the extension. Such decision by the Plan
Administrator shall not be subject to further review. If a decision on review is
not furnished to a claimant within the specified time period, the claim will be
deemed to have been denied on review.

     (c)    EXHAUSTION OF REMEDY. No claimant shall institute any action or
proceeding in any state or federal court of law or equity, or before any
administrative tribunal or arbitrator, for a claim for benefits under the Plan
until he or she has first exhausted the procedures set forth in this section.

     10.08  APPOINTMENT OF TRUSTEE

     The Trustee will be appointed by the Board.

     10.09  LIMITATION OF LIABILITY

                                                                              83
<Page>

     The Company, the Board, the Named Fiduciaries, the Plan Administrator, the
Employers and any officer, Employee or agent of the Company and each Employer
shall not incur any liability individually or on behalf of any other individuals
or on behalf of the Company or Employers for any act or failure to act, made in
good faith in relation to the Plan or the funds of the Plan. However, this
limitation shall not act to relieve any such individual or the Company or
Employers from a responsibility or liability for any fiduciary responsibility,
obligation or duty under Part 4, Title I, of ERISA.

                                                                              84

                                  MISCELLANEOUS

     11.01  EXCLUSIVE BENEFIT - AMENDMENTS

     It shall be impossible for any part of the corpus or income of the Trust
Fund, ESOP Trust Fund or the TRASOP Trust Fund to be used for or diverted to
purposes other than for the exclusive benefit of Participants or Beneficiaries
entitled to benefits under the Plan and for paying the expenses of the Plan. No
person has any interest in, or right to, any part of the Trust Fund except as
and to the extent expressly provided in the Plan. Subject to the foregoing, the
Plan may be amended, in whole or in part, at any time and from time to time by
the Board or pursuant to authority granted by the Board and any amendment may be
given such retroactive effect as the Board or its duly authorized delegate may
determine. If an Employer, other than CECONY, wishes to amend the Plan as to its
participating employees, that Employer will present a resolution of its board of
directors approving the proposed amendment and requesting CECONY to amend the
Plan. CECONY shall have the sole discretion whether to amend the Plan as
requested by an Employer.

     Solely in this Article XI, the term Plan includes the Thrift Savings Plan,
the ESOP and the TRASOP and reference to the Trust Fund includes the ESOP Trust
Fund and the TRASOP Trust Fund, unless the context clearly designates otherwise.

     11.02  TERMINATION - SALE OF ASSETS OF SUBSIDIARY

     (a)    The Plan may be partially or fully terminated or contributions may
be permanently discontinued for any reason at any time by the Board. In the
event of a partial or total termination of the Plan or permanent discontinuance
of contributions under the Plan:

                                                                              85
<Page>

(i) no contribution will be made thereafter except for a Payroll Period the last
day of which coincides with or precedes such termination or discontinuance; (ii)
no distribution shall be made except as provided in the Plan; (iii) the rights
of all Participants to the entire amounts to the credit of their Account
Balances as of the date of such termination or partial termination or
discontinuance shall become 100% vested; (iv) no person shall have any right or
interest except with respect to the Trust Fund; (v) any remaining forfeitures
shall be considered a special Employer Contribution and shall be allocated on a
pro-rata basis, based on Account Balance, to all Participants with an Account
Balance as of the date of termination, partial termination or discontinuance;
and (vi) the Trustee shall continue to act until the Trust Fund shall have been
distributed in accordance with the Plan.

     (b)    Upon termination of the Plan, Pre-Tax Contributions, with Earnings,
will be distributed to Participants only if neither the Company, Employers nor
an Affiliate establishes or maintains a successor defined contribution plan. For
purposes of this paragraph, a "successor defined contribution plan" is a defined
contribution plan, other than an employee stock ownership plan as defined in
Code Section 4975(e)(7) or a simplified employee pension as defined in Code
Section 408(k) which exists at the time the Plan is terminated or within the
12-month period beginning on the date all assets are distributed. A defined
contribution plan will not be deemed a successor plan if fewer than two percent
of the Employees who are eligible to participate in the Plan at the time of its
termination are or were eligible to participate under another defined
contribution plan of the Company or an Affiliate (other than an ESOP or a SEP)
at any time during the period beginning 12 months before and ending 12 months
after the date of the Plan's termination.

                                                                              86
<Page>

     11.03  BENEFICIARIES

     Upon the death of a Participant, his or her Account Balance shall be
payable in a lump sum to his or her surviving spouse. If there is no surviving
spouse or the surviving spouse has consented, in the manner provided in this
Section 11.03, to a designation of a Beneficiary in addition to or instead of
such spouse, and such designation is in effect at the time of the Participant's
death, the Participant's Account Balance will be paid to such Beneficiary.
Effective beginning June 1, 2002, the surviving spouse or Beneficiary(ies) may
elect to take a distribution in monthly, quarterly or yearly installments up to
but not exceeding a 15-year period; providing, however, that any distribution
election is consistent with Code Section 401(a)(9) and the regulations
promulgated thereunder. Each Participant may designate a primary or contingent
Beneficiary or Beneficiaries in the event of the death of the Participant prior
to distribution of such benefits. The Participant may file a written designation
with the Plan, on a form furnished by the Plan Administrator, or his or her
delegate. Such designation shall be effective only if (1) such designation is
accompanied by the written consent of the Participant's spouse which
acknowledges the effect on the spouse of the designation and it witnessed by a
notary public, or (2) the Participant if not married. Any such designation made
by an unmarried Participant shall become null and void in the event the
unmarried Participant marries before his or her Annuity Starting Date. Any
consent of a spouse shall be effective only with respect to such spouse. If, at
the time of a Participant's death, there is no surviving spouse of the
Participant and no designation of a Beneficiary by such Participant is in
effect, then the Participant's benefits shall be payable to his or her estate or
legal representative. A Participant may revoke a designation made pursuant to
this Section 11.03 by signing and filing with the Plan Administrator or his or
her delegate a written instrument to that effect, in such manner and on such
conditions as may be

                                                                              87
<Page>

prescribed by the Plan Administrator, or by filing a new designation pursuant to
this Section 11.03. The consent of a Participant's spouse may not be revoked,
but such spouse's consent shall be required for every designation of a
Beneficiary other than the Participant's spouse and for every change in any such
designation. The requirement for spousal consent may be waived by the Plan
Administrator if he or she believes there is no spouse, or the spouse cannot be
located, or because of such other circumstances as may be established by
applicable law.

     11.04  ASSIGNMENT OF BENEFITS

     (a)    No Participant or Beneficiary shall have the right to assign,
transfer, alienate, pledge, encumber or subject to lien any benefits to which he
or she is entitled under the Plan. Nothing in this Section shall preclude
payment of Plan benefits pursuant to a qualified domestic relations order as
defined in Code Section 414(p) and Section 206(d) of ERISA. The Plan
Administrator will establish a written procedure to determine the qualified
status of domestic relations orders and to administer distributions under such
qualified orders.

     (b)    Notwithstanding anything herein to the contrary, if the amount
payable to the alternate payee under the qualified domestic relations order is
$5,000 or less, such amount shall be paid in one lump sum as soon as practicable
following the qualification of the order. If the amount exceeds $5,000, it may
be paid as soon as practicable following the qualification of the order if the
alternate payee consents thereto; otherwise it may not be payable before the
earliest of (1) the Participant's termination of employment, (2) the time such
amount could be withdrawn under Article 7 or (3) the Participant's attainment of
age 50.

     (c)    A Participant's Account Balance may be offset against the amount
owed to the Plan as a result of a breach of fiduciary duty to the Plan or
criminality involving the Plan.

                                                                              88
<Page>

The participant's Account Balance will be reduced to satisfy liabilities of the
Participant to the Plan due to: (1) the Participant being convicted of
committing a crime involving the Plan; (2) a civil judgment (or consent order or
decree) being entered by a court in an action brought in connection with a
violation of ERISA's fiduciary duty rules; or (3) a settlement agreement between
the Secretary of Labor and the Participant in connection with a violation of
ERISA's fiduciary rules. If the Participant is married at the time at which the
offset is to be made, either the Participant's spouse must consent in writing to
these offset (unless there is no spouse, the spouse cannot be located, or due to
other circumstances prescribed by the Secretary pursuant to Code Section
417(a)(2)(B)), or a spousal waiver of survivor benefits must be in effect for
the offset to take place. Spousal consent is not required if the spouse is
ordered or required by the judgment, order, decree, or settlement to pay an
amount to the Plan in connection with a violation of Part 4 of Title I of ERISA.
Spousal consent is not required where, in the judgment, order, decree, or
settlement, the spouse retains the right to receive a 50% survivor annuity under
a qualified joint and survivor annuity and under a qualified pre-retirement
survivor annuity. The amount of a benefit that is so offset is includible in
income on the date of the offset.

                                                                              89

     11.05  MERGER

     The Plan may not be merged or consolidated with, or its assets or
liabilities may not be transferred to any other plan unless each person entitled
to benefits under the Plan would, if the resulting plan were then terminated,
receive immediately after the merger or consolidation, or transfer of assets or
liabilities, a benefit which is equal to or greater than the benefit he or she
would have been entitled to receive immediately before the merger, consolidation
or transfer if the Plan had then terminated.

     In the event of a corporate transaction, divestiture of assets or an
Affiliate, or other corporate reorganization in which one or a group of
Participants are transferred to another employer, the Plan Administrator, in his
or her sole discretion, may effectuate a trust-to-trust transfer of affected
Participants' Account Balance to the other employer's qualified defined
contribution plan.

     In the event of a corporate acquisition, merger, or other corporate
reorganization in which one or a group of persons become Employees, the Plan
Administrator, in his or her sole discretion, or if CECONY so requires, may
accept a trust-to-trust transfer of the affected persons' Account Balance from
another employer's qualified defined contribution plan to the Plan.

     11.06  CONDITIONS OF EMPLOYMENT NOT AFFECTED BY PLAN

     The establishment and maintenance of the Plan shall not confer any legal
rights upon any Employee or other person for a continuation of employment, nor
shall it interfere with the rights of the Employers to discharge any Employee
and to treat him or her without regard to the effect which that treatment might
have upon him or her as a Participant or potential Participant of the Plan.

     11.07  FACILITY OF PAYMENT

                                                                              90
<Page>

     If the Plan Administrator finds that a Participant or other person entitled
to a benefit is unable to care for his or her affairs because of illness or
accident or is a minor, the Plan Administrator may direct that any benefit due
him or her, unless claim has been made by a duly appointed legal representative,
be paid to his or her spouse, a child, a parent or other blood relative, or to a
person with whom he or she resides. Any payment so made shall be a complete
discharge of the liabilities of the Plan for that benefit.

     11.08  INFORMATION

     Each Participant, Beneficiary or other person entitled to a benefit, before
any benefit is payable to him or her/on his or her account under the Plan, shall
file with the Plan Administrator the information that the Plan Administrator
requires to establish his or her rights and benefits under the Plan.

     11.09  ADDITIONAL PARTICIPATING EMPLOYERS

     (a)    If any entity is or becomes an Affiliate, the Board may include the
employees of that Affiliate in the participation of the Plan upon appropriate
action by that Affiliate necessary to adopt the Plan. If any person becomes an
Employee as the result of a merger, a consolidation, or an acquisition of all or
part of the assets or business of another company, the Board shall determine to
what extent, if any, previous service with the other entity will be recognized
under the Plan, subject to the continued qualification of the trust for the Plan
as tax-exempt under the Code.

     (b)    An Employer may terminate its participation in the Plan upon
appropriate action. In that event, the funds of the Plan held on account of
Participants in the employ of that Affiliate, and any unpaid Account Balances of
Participants who have separated from the employ of that Affiliate, shall be
determined by the Plan Administrator. Those funds will be distributed as
provided in and permitted under Section 11.02 if the Plan, as to that employer,

                                                                              91
<Page>

is terminated, or segregated by the Trustee to a separate trust, pursuant to
certification to the Trustee by the Plan Administrator, continuing the Plan as a
separate plan for the employees of that Affiliate under which the board of
directors of that Affiliate will succeed to all the powers and duties of the
Board, including the appointment of named fiduciaries and plan administrator.

     11.10  IRS DETERMINATION

     All contributions made to the Trust Fund, and all loans made pursuant to
Article 9, which are made prior to the receipt of a determination from the
Internal Revenue Service to the effect that the Plan is a qualified plan under
Code Sections 401 (a) and 401(k) or the refusal of the IRS in writing to issue
such a determination, shall be made on the express condition that such
determination is received. In the event the Internal Revenue Service determines
that the Plan is not so qualified or refuses in writing to make such
determination, such contributions, increased by any earnings thereon, and
reduced by any losses thereon and by the outstanding balance (principal and
interest) on any loans made under Article 9, shall be returned to the
Employer(s) and Participants, as appropriate, as promptly as practicable after
such determination. In the event the Internal Revenue Service requires
reductions in such contributions and/or changes in the terms and conditions of
such loans as a condition of its determination that the Plan is so qualified,
the required reductions in contributions, increased by any earnings and reduced
by any losses attributable thereto, shall be returned to the Employer(s) and
Participants, as appropriate, and/or the amounts and terms and conditions of any
such outstanding loans shall be modified to meet Internal Revenue Service
requirements, as promptly as practicable after notification from the Internal
Revenue Service. If all or part of an Employer's deductions under Code Section
404 for Employer Contributions to the Plan are disallowed by the Internal
Revenue Service, the portion of the

                                                                              92
<Page>

Employer Contributions to which the disallowance applies shall be returned to
that Employer without earnings thereon, but reduced by any losses attributable
thereto. The return shall be made within one year after the denial of
qualification or disallowance of deduction, as the case may be.

     11.11  MISTAKEN CONTRIBUTIONS

     Any contribution made by mistake of fact shall be returnable, without any
earnings thereon but reduced by any losses attributable thereto, to the
Employer(s) and/or Participants, as appropriate within one year after the
payment of the contribution.

     11.12  PREVENTION OF ESCHEAT

     If the Plan Administrator cannot ascertain the whereabouts of any person to
whom a payment is due under the Plan, the Plan Administrator may, no earlier
than three years from the date such payment is due, mail a notice of such due
and owing payment to the last known address of such person, as shown on the
records of the Plan or Employer. If such person has not made written claim
therefor within three months of the date of the mailing, the Plan Administrator
may, if he or she so elects and upon receiving advice from counsel to the Plan,
direct that such payment and all remaining payments otherwise due such person be
canceled on the records of the Plan and the amount thereof applied to reduce the
contributions of the applicable Employer. Upon such cancellation, the Plan and
the Trust shall have no further liability therefor except that, in the event
such person or his or her beneficiary later notifies the Plan Administrator of
his or her whereabouts and requests the payment or payments due to him under the
Plan, the amount so applied shall be paid to him or her in accordance with the
provisions of the Plan.

     11.13  CONSTRUCTION

                                                                              93

     The Plan shall be construed, regulated and administered under ERISA and the
laws of the State of New York, except where ERISA controls. In the event a
claimant institutes an action or proceeding in any state or federal court of law
or equity, the applicable "statute of limitations" for such action will be New
York State statute for actions brought in contract matters.

                                                                              94

                                   ARTICLE XII

                              TOP-HEAVY PROVISIONS

     12.01  APPLICATION OF TOP-HEAVY PROVISIONS

     This Article XII shall apply for purposes of determining whether the plan
is a top-heavy plan under Code Section 416(g) for Plan Years beginning after
December 31, 2001, and whether the Plan satisfies the minimum benefit
requirements of Code Section 416(c) for such years.

     12.02  MINIMUM BENEFIT FOR TOP-HEAVY YEAR

     (a)    KEY EMPLOYEE. Key Employee means any Employee or former Employee
(including any deceased Employee) who at any time during the Plan Year that
includes the determination date was an officer of the Company or Affiliate
having Annual Compensation greater that $130,000 (as adjusted under Code Section
416(i)(1) beginning after December 31, 2002, a 5-percent owner of the Company or
Affiliate or a 1-percent owner of the Company or Affiliate having Annual
Compensation of more than $150,000. The determination of who is a Key Employee
will be made in accordance with Code Section 416(i)(1) and the applicable
regulations and other guidance of general applicability issued thereunder.

     (b)    DETERMINATION OF PRESENT VALUES AND AMOUNTS. This section 12.02(b)
shall apply for purposes of determining the present values of accrued benefits
and the amounts of Account Balances of Employees as of the determination date.

            (i)   Distributions during the year ending on the determination
                  date. The present values of accrued benefits and the amounts
                  of Account Balances of an Employee as of the determination
                  date shall be increased by the

                                                                              95
<Page>

                  distributions made with respect to the Employee under the Plan
                  and any Plan aggregated with the Plan under Code Section
                  416(g)(2) during the 1-year period ending on the determination
                  date. The preceding sentence shall also apply to distribution
                  under a terminated plan which, had if not been terminated,
                  would have been aggregated with the plan under Code Section
                  416(g)(2)(A)(i). In the case of a distribution made for a
                  reason other than separation from service, death, or
                  disability, this provision shall be applied by substituting
                  "5-year period" for "1-year period."

            (ii)  Employees not performing services during year ending on the
                  determination date. The accrued benefits and Account Balances
                  of any individual who has not performed services for the
                  Company or an Affiliate during the 1-year period ending on the
                  determination date shall not be taken into account.

     12.03  MINIMUM BENEFITS

     Matching Contributions. Employer Contributions shall be taken into account
for purposes of satisfying the minimum contribution requirements of Code Section
416(C)(2) and the Plan. Employer Contributions that are used to satisfy the
minimum contribution requirements shall be treated as matching contributions for
purposes for the Actual Contribution Percentage Test and other requirements of
Code Section 401(m).

     12.04  AGGREGATION GROUPS

     (a)    Notwithstanding anything to the contrary herein, this Plan shall not
be a Top-Heavy Plan if it is part of either a "required aggregation group" or a
"permissive aggregation group" that is not a Top-Heavy Group.

     (b)    The "required aggregation group" consists of:

                                                                              96
<Page>

            (i)   Each Defined Contribution Plan or Defined Benefit Plan in
                  which at least one Key Employee participates; and

            (ii)  Each other Defined Contribution Plan or Defined Benefit Plan
                  which enables a plan referred to in the preceding subparagraph
                  (i) to meet the nondiscrimination requirements of Section
                  401(a)(4) or 410 of the Code.

     (c)    A "permissive aggregation group" consists of the plans included in
the "required aggregation group" plus any one or more other Defined Contribution
Plans or Defined Benefit Plans which, when considered as a group with the
"required aggregation group", would continue to meet the nondiscrimination
requirements of Section 401(a)(4) and 410 of the Code.

     12.05  SPECIAL BENEFIT LIMITS

     For any Plan Year for which this Article 12 is applicable the definitions
of "Defined Benefit Plan Fraction" and "Defined Contribution Plan Fraction" in
Sections 1.20 and 1.22, respectively, shall be modified in each case by
substituting "1.0"for "1.25".

     12.06  SPECIAL DISTRIBUTION RULE

     For any Plan Year for which this Article 12 is applicable, Section 7.08(a)
shall apply to Key Employees.

                                                                              97

                                  ARTICLE XIII

                     TAX REDUCTION ACT STOCK OWNERSHIP PLAN

     13.01  PURPOSE - SEPARATE ENTITY

     (a)    The TRASOP, is a stock bonus plan, established under the Tax
Reduction Act of 1975 was intended to give eligible participants an equity
interest in CECONY and encourage those participants to remain in the employ of
CECONY. The TRASOP is invested in Shares and in a short-term investment fund of
cash and cash equivalents. Applicable laws do not permit additional
contributions to the TRASOP. CECONY desires to continue the TRASOP Accounts of
Participants having such accounts. Effective as of July 1, 1988, all TRASOP
Accounts were transferred to this Plan, and all TRASOP provisions which continue
to be applicable were added to this Plan and shall, together with other
applicable provisions of this Plan, govern the TRASOP Accounts.

     (b)    Participant's Plan Account Balances and TRASOP Accounts shall be
administered separately, although they shall be held as part of the same Trust
Fund. There shall be no transfers between TRASOP Accounts and Plan Accounts.

     (c)    All matters relating to the TRASOP which relate to or arise out of
facts, circumstances or conditions in effect prior to July 1, 1988, shall be
governed by the provisions of the TRASOP as in effect on June 30, 1988 prior to
the merger, unless expressly otherwise provided in this Plan.

     (d)    Effective on or after January 1, 2002, the Economic Growth and Tax
Reduction Recovery Act of 2001 amended the definition of applicable dividend to
allow a deduction for dividends paid on applicable employer securities with
respect to which participants or beneficiaries are provided an election to have
the dividend paid to an ESOP

                                                                              98
<Page>

and distributed in cash, or reinvested in qualifying employer securities. The
deduction is available both with respect to dividends that are reinvested and
paid out in cash. Accordingly, effective January 1, 2002, the TRASOP is being
amended to provide participants or beneficiaries with the election to have
dividends paid in cash or reinvested, as set forth below.

     13.02  TRASOP ACCOUNTS - APPLICATION OF DIVIDENDS

     (a)    The TRASOP Account of each Participant in TRASOP who remained in the
employ of CECONY on July 1, 1988 was transferred to this Plan effective as of
July 1, 1988. Each such Participant shall continue to have a nonforfeitable
right to all Shares allocated and all amounts credited to such Participant's
TRASOP Account.

     (b)    All dividends received by the Trustee with respect to Shares
allocated to the TRASOP Accounts of Participants shall be applied to the
purchase of additional Shares. Such purchases shall be made promptly after the
receipt of each such dividend. The Trustee shall purchase, in one or more
transactions, the maximum number of whole Shares obtainable at then prevailing
prices, including brokerage commissions and other reasonable expenses incurred
in connection with such purchases. Such purchases may be made on any securities
exchange where Shares are traded, in the over-the-counter market, or in
negotiated transactions, and may be on such terms as to price, delivery and
otherwise as the Trustee may determine to be in the best interest of the
Participants. The Trustee shall complete such purchases as soon as practical
after receipt of such dividends, having due regard for any applicable
requirements of law affecting the timing or manner of such purchases. The
additional Shares so purchased shall be allocated among the respective TRASOP
Accounts of the Participants in proportion to the number of Shares in each
TRASOP Account at the record date for the payment of the dividend so applied.
Such allocation shall be made as

                                                                              99
<Page>

promptly as practicable but for purposes of determining the time at which such
additional Shares shall become distributable pursuant to Section 13.04, the
additional Shares so allocated to each Participant's TRASOP Account shall be
deemed to have been allocated as of the respective allocation dates of the
Shares in such TRASOP Account at such record date, in proportion to the number
of such Shares previously allocated as of each such allocation date.

     (c)    For Plan Years beginning on and after January 1, 2002, dividends
received by the Trustee with respect to Shares allocated to the TRASOP accounts
of Participants, in accordance with the election of the Participant, will be
either paid in cash to Participants not later than 90 days after the close of
the Plan Year in which the dividends are paid, or applied by the Trustee for the
purchase of additional shares. A Participant will be given a reasonable
opportunity before a dividend is paid or distributed to make the election and
can change a dividend election at least annually. If there is a change in the
Plan governing the manner in which the dividends are paid or distributed to
Participants, each Participant will be given a reasonable opportunity to make an
election under the new Plan terms prior to the date on which the first dividend
subject to the new Plan terms is paid or distributed. A Participant who fails to
make an election as to whether to receive his or her dividend in cash or have
such dividend reinvested will be treated as if he or she elected to have his or
her dividend reinvested until such time that he or she makes an affirmation
election for a distribution of the dividend. Dividends that are distributed will
be held and invested in a short-term investment fund or like kind of cash
account until distributed.

     13.03  VOTING RIGHTS, OPTIONS, RIGHTS, AND WARRANTS

     (a)    Each Participant shall be entitled to direct the Trustee as to the
manner in which any Shares or fractional Shares allocated to the Participant's
TRASOP Account are to

                                                                             100
<Page>

be voted.

     (b)    In the event that any option, right, or warrant shall be granted or
issued with respect to any Shares allocated to the Participant's TRASOP Account,
each Participant shall be entitled to direct the Trustee whether to exercise,
sell, or deal with such option, right, or warrant.

     (c)    The Trustee shall keep confidential the Participant's voting
instructions and instructions as to any option, right or warrant and any
information regarding a Participant's purchases, holdings and sales of Shares.

     13.04  DISTRIBUTION OF SHARES

     (a)    Each Share allocated to a Participant's TRASOP Account shall be
available for distribution to such Participant promptly after the earlier of the
death, disability or termination of employment of such Participant.

     (b)    Each Share which shall become distributable to a Participant by
reason of clause (a)(i) above is herein called, from the time such Share shall
become so distributable, an Unrestricted Share. Notwithstanding the provisions
of the aforesaid clause A.(i), Unrestricted Shares shall be distributed to
Participants as follows:

            (i)   From time to time, a Participant may request, in such manner
                  and on such conditions as may be prescribed by CECONY, that
                  Unrestricted Shares held in the Participant's TRASOP Account
                  be distributed to the Participant. If such Participant is
                  married, the written application shall include written consent
                  of the Participant's spouse witnessed by a Notary Public.
                  Spousal consent shall not be required with respect to
                  withdrawal requests made on or after March 1, 1994.
                  Applications made in a calendar month shall be effective as of
                  the last day of such calendar

                                                                             101
<Page>

                  month. Any such request must be for whole Shares only and must
                  be for at least ten Shares or the number of whole Unrestricted
                  Shares in the TRASOP Account, whichever is less.

            (ii)  Certificates for Unrestricted Shares requested in accordance
                  with the preceding paragraph B(a) shall be delivered, or a
                  cash distribution in respect of such Unrestricted Shares if
                  elected by the Participant pursuant to Section 13.04D below
                  shall be made, to the Participant as soon as practicable after
                  the effective date of the application.

            (iii) Any Unrestricted Share which shall become distributable by
                  reason of any provision of this Plan other than clause A.(i)
                  above (including, without limitation, provision for
                  distribution upon the death, disability or termination of
                  employment of the Participant) shall be distributed in
                  accordance with such provision.

     (c)    In the case of death of a Participant, distributions in respect of
Shares allocated to the Participant's TRASOP Account shall be made to the
Participant's Beneficiary. In the case of disability or termination of
employment with the Company or an Affiliate of a Participant, distributions in
respect of Shares allocated to the Participant's TRASOP Account shall be made to
the Participant.

     All distributions under the TRASOP will begin, subject to Section 7.08 and
Subsection 13.04.F, not later than the 60th day after the close of the Plan Year
in which the latest of the following events occurs: (1) the Participant attains
age 65, (2) the 10th anniversary of the year in which the Participant commenced
participation in TRASOP, or (3)

                                                                             102
<Page>

the Participant becomes disabled, dies or terminates employment with the Company
or an Affiliate.

     (d)    All distributions from a Participant's TRASOP Account shall be made
in Shares; provided, however, that a Participant or Beneficiary shall have the
right to elect, on a form furnished by and submitted to CECONY, to receive a
distribution, other than a distribution upon termination of TRASOP, in cash.
Except in the case of a final distribution from a Participant's TRASOP Account
and a distribution of the Participant's entire TRASOP Account balance after such
time as all Shares in a Participant's TRASOP Account have become Unrestricted
Shares, all distributions from such TRASOP Account shall be made in respect of
whole Shares only, and any fractional Share which is otherwise distributable
shall be retained in such TRASOP Account until it can be combined, in whole or
in part, with another fractional Share which shall subsequently become
distributable, so as to make up a whole Share. In the case of a final
distribution from a Participant's TRASOP Account (except a distribution upon
termination of the TRASOP) or in the case of a distribution of the Participant's
entire TRASOP Account balance after such time as all of the Shares in the
Participant's TRASOP Account have become Unrestricted Shares, such distribution
shall be made in respect of the number of whole Shares then remaining in the
Participant's TRASOP Account, together with a cash payment in respect of any
fractional Share based on the closing price of a Share as reported on the New
York Stock Exchange consolidated tape on the last trading day of the month
immediately preceding the month in which such final distribution is made. The
Trustee, in each such case, shall purchase such fractional Share from the
Participant at a price equal to the cash payment to be made to the Participant.
Whenever the Trustee requires funds for the purchase of fractional Shares, such
funds shall be drawn from

                                                                             103
<Page>

the accumulated income of the TRSOP Trust Fund, if any, and otherwise shall be
advanced by CECONY upon the Trustee's request, subject to reimbursement from
future income of the TRASOP Trust. All fractional Shares so purchased by the
Trustee shall be allocated to the TRASOP Accounts of the remaining Participants
at such intervals as shall be determined by the Plan Administrator, but no later
than the end of the next succeeding Plan Year. The Trustee shall sell any Shares
in respect of which a cash distribution is to be made. The Trustee may make such
sales on any securities exchange where Shares are traded, in the
over-the-counter market, or in negotiated transactions. Such sales may be on
such terms as to price, delivery and otherwise as the Trustee may determine to
be in the best interests of the Participants. The Trustee shall complete such
sales as soon as practical under the circumstances having due regard for any
applicable requirements of law affecting the timing or manner of such sales. All
brokerage commissions and other direct selling expenses incurred by the Trustee
in the sale of Shares under this Subsection 13.04D shall be paid as provided in
Section 10.05.

     (e)    Upon any termination of TRASOP pursuant to Section 11.02, the Trust
shall continue until all Shares which have been allocated to Participants'
TRASOP Accounts have been distributed to the Participants, unless the Board
directs an earlier termination of the TRASOP Trust Fund. Upon the final
distribution of Shares, or at such earlier time as the Board shall have fixed
for the termination of the TRASOP Trust Fund, the Plan Administrator shall
direct the Trustee to allocate to the Participants any Shares then held by the
Trustee and not yet allocated, and the Trustee shall distribute to the
Participants any whole Shares which have been allocated to their TRASOP Accounts
but which have not been distributed, shall sell all fractional Shares and
distribute the proceeds to the respective

                                                                             104
<Page>

Participants entitled to such fractional Shares, shall liquidate any remaining
assets (other than Shares) held by the TRASOP Trust Fund, and shall apply the
proceeds of such liquidation and any remaining funds held by the Trustee, the
disposition of which is not otherwise provided for, to a distribution to all
Participants then receiving a final distribution of Shares, in proportion to the
whole and fractional Shares to which each is entitled; and the TRASOP Trust Fund
shall thereupon terminate.

     (f)    Notwithstanding any other provision of this Plan, unless a
Participant otherwise elects in writing on a form furnished by CECONY:

     A.     Distribution of a Participant's TRASOP Account balance will commence
            not later than one

       (1)  year after the close of the Plan Year (1) in which the Participant
            terminates employment with the Company or an Affiliate by reason of
            Retirement upon or after attainment of Normal Retirement Age, death,
            or disability, or

       (2)  which is the fifth Plan Year following the Plan Year in which the
            Participant terminates employment for any other reason, and the
            Participant is not reemployed before such Plan Year.

     B.     Distribution of the Participant's TRASOP Account balance will be in
            five (5) annual distributions as promptly as practicable after the
            end of each Plan Year; provided, however, that a TRASOP Account
            balance that equals $5,000 or less shall be distributed in a single
            distribution as soon as practicable, but not later than 60 days
            after the close of the Plan Year in which the Participant's
            termination of employment occurs. Each such annual distribution
            shall be in respect of the number of Shares, rounded down to the

                                                                             105
<Page>

            nearest number of whole Shares, which most closely approximates the
            entire balance in the Participant's TRASOP Account as of December 31
            of the previous year divided by the number of annual distributions
            remaining to be made under this subsection, except that the fifth
            such distribution shall be respect of the entire balance in the
            Participant's TRASOP Account as of the preceding December 31. Each
            such annual distribution shall be taken pro rata from all
            contribution years in Participant's TRASOP Account.

     C.     A Participant whose employment with the Company or an Affiliate is
            terminated by reason of Retirement, disability or any other reason
            (other than death) may elect in such a manner and on such conditions
            as may be prescribed by CECONY to have his TRASOP Account balance
            distributed in one of the following forms:

            (i)   a single lump sum distribution as soon as practicable, but not
                  later than 60 days after the end of the Calendar Year in which
                  the Participant's termination of employment occurs; or

            (ii)  a distribution deferred until the last day of a calendar month
                  not later than the calendar month in which the Participant
                  attains age 70, as designated by the Participant, in which
                  event the distribution of the Participant's TRASOP Account
                  balance as of the last day of the calendar month so designated
                  by the Participant shall be made in a single lump sum as soon
                  as practicable after such calendar month.

     13.00  DIVERSIFICATION OF TRASOP ACCOUNTS

     (a)    DEFINITIONS: The following terms shall have the following meanings
for purposes of this Section 13.05:

                                                                             106
<Page>

            (i)   Qualified Participant shall mean a Participant who has a
                  TRASOP Account and has attained at least age 55 and completed
                  at least 10 years of participation in TRASOP.

            (ii)  Qualified Election Period shall mean the first ninety (90)
                  days following the end of each Plan Year.

            (iii) Eligible Shares shall mean Shares added to a Participant's
                  TRASOP Account after December 31, 1986.

            (iv)  Diversifiable Amount shall, with respect to any Qualified
                  Election Period, mean twenty-five percent (25%) of the number
                  of Eligible Shares in the Participant's TRASOP Account as of
                  the end of the preceding Plan Year. However, if the
                  Diversifiable Amount for any Qualified Election Period shall
                  have a value which may be deemed de minimis under regulations
                  issued by the Secretary of the United States Department of the
                  Treasury, then there shall be no Diversifiable Amount
                  available for such Qualified Election Period.

     (b)    ELIGIBILITY FOR DIVERSIFICATION: Each Qualified Participant shall
have the right to elect to diversify, by means of a distribution of whole
Eligible Shares only, all or some portion of the Diversifiable Amount in his
TRASOP Account during each of the six (6) consecutive Qualified Election Periods
following the Plan Year in which such Participant first became a Qualified
Participant, provided, however, that, notwithstanding subsection 13.05.A.(d),
the Diversifiable Amount in the sixth Qualified Election Period for each
Qualified Participant shall be fifty percent (50%) of the number of Eligible
Shares in his TRASOP Account as to the end of the preceding Plan Year. A
distribution pursuant to this

                                                                             107
<Page>

Article 13.05 must be a minimum of ten (10) Shares, or all Whole Shares
comprising the Diversifiable Amount for such Qualified Election Period if less
than 10. Each Qualified Participant who desires to elect diversification under
this Section shall, during the Qualified Election Period, complete and execute a
diversification election and consent form provided by CECONY. Such election may
be revoked or modified or a new election may be made in its stead within the
Qualified Election Period, upon the expiration of which the diversification
election shall be irrevocable.

     (c)    DIVERSIFICATION PROCEDURE

            (i)   The TRASOP shall, within the 90 day period following each
                  Qualified Election Period, distribute to each Qualified
                  Participant who has elected to diversify under this Section,
                  the number of whole Eligible Shares which most closely
                  approximates, but does not exceed, the number of Eligible
                  Shares duly elected to be diversified by each such Qualified
                  Participant. Failure by a Qualified Participant to provide
                  required consents to distribution of any Diversifiable Amount,
                  shall relieve the TRASOP of all obligation to make any such
                  distribution.

            (ii)  To the extent a Qualified Participant has Eligible Shares
                  which are Unrestricted Shares in his TRASOP Account, such
                  Unrestricted Shares shall be distributed pursuant to this
                  Section 13.05. Only upon exhaustion of all such Unrestricted
                  Shares may additional Eligible Shares then be distributed
                  hereunder.

                                                                             108

                                   ARTICLE XIV

                          EMPLOYEE STOCK OWNERSHIP PLAN

     14.01  PURPOSE - SEPARATE ENTITY

     (a)    Effective as of the ESOP Effective Date, the Company established the
Consolidated Edison Employee Stock Ownership Plan ("ESOP") as a portion of,
included within and separate from the Thrift Plan. The ESOP affords special
rights and has specific requirements which must be satisfied that are distinct
from the Thrift Plan, such as the right of an ESOP Participant to: (1) vote his
or her allocated Shares; (2) request his or her distribution be in the form of
Shares; (3) diversify his or her ESOP Account; (4) elect to take dividends in
cash or have dividends reinvested; and, (5) be 100% fully invested immediately
in those Shares purchased by reinvested dividends. Each of these distinct ESOP
rights and requirements is set forth in the Thrift Plan and obligations in the
Thrift Plan such as those requirements regarding eligibility to participate,
vesting, distributions, in-service distributions, operational, administrative
and fiduciary requirements continue to apply to the ESOP and are deemed
incorporated into and so are not repeated in this Article XIV. The ESOP is
intended to be an employee stock ownership plan within the meaning of Code
Section 4975(e)(7). The ESOP is intended to give ESOP Participants an equity
interest in CEI and encourage ESOP Participants to remain in the employ of CEI.

     (b)    Effective as of the ESOP Effective Date, the part of a Participant's
Employer Contributions Subaccount invested in the Company Stock Fund in the
Thrift Plan was transferred to the ESOP and ESOP Trust Fund and established and
included into the Participant's ESOP Account.

     (c)    Participants' ESOP Accounts will be held in the ESOP Trust Fund and

                                                                             109
<Page>

administered separately, although they shall be held as part of the same Trust
Fund. Participants are permitted to transfer assets to and from their ESOP
Accounts to their Thrift Plan Accounts within the ESOP Trust Fund and the Trust
Fund.

     14.02  SPECIAL DEFINITIONS FOR ESOP

     (a)    The following terms shall have the following meanings for purposes
of the ESOP:

     (i)    ESOP ACCOUNT means the account into which is credited a
            Participant's Employer Contributions' invested in the Company Stock
            Fund and dividends paid on these Shares and comprising the following
            Subaccounts:

       (1)  the Participant's TRANSFERRED ESOP SUBACCOUNT which is the
            Participant's Company Stock Fund that was transferred from the
            Thrift Plan to the ESOP as of the ESOP Effective Date;

       (2)  a Participant's DIVIDEND SUBACCOUNT which, for a Participant who is
            credited with less than three Years of Service, consists solely of
            Shares purchased with reinvested dividends after the ESOP Effective
            Date and are 100% fully vested at all times; and

       (3)  a Participant's ESOP SUBACCOUNT which is the account into which is
            credited a Participant's Employer Contributions contributed to the
            ESOP after the ESOP Effective Date.

       (4)  Once a Participant is credited with at least three Years of Vesting
            Service, his or her Dividend Subaccount will be merged into his or
            her ESOP Subaccount. After the ESOP Effective Date, a Participant's
            ESOP Subaccount will include any Employer Contributions invested in
            the other Investment Funds to the extent such amounts were ever at
            any time invested in the ESOP after the ESOP Effective Date.

                                                                             110
<Page>

     (ii)   ESOP EFFECTIVE DATE means May 8, 2002.

     (iii)  ESOP PARTICIPANT means a Participant in the Thrift Plan who has
            elected to invest some or all of his or her Employer Contributions
            in the Company Stock Fund.

     (iv)   DIVERSIFIABLE ESOP AMOUNT, with respect to any Qualified ESOP
            Election Period, means 25% of the number of Shares in the
            Participant's ESOP Account as of the end of the preceding Plan Year.
            However, if the Diversifiable ESOP Amount for any Qualified ESOP
            Election Period has a value which may be deemed de minimis under
            regulations issued by the Secretary of the United States Department
            of the Treasury, then there will be no Diversifiable ESOP Amount
            available for such Qualified ESOP Election Period.

     (v)    QUALIFIED ESOP PARTICIPANT shall mean an ESOP Participant who has an
            ESOP Account, attained at least age 55 and completed at least 10
            years of participation in the ESOP. Years of participation in the
            Thrift Plan will be taken into account in determining whether a
            Qualified ESOP Participant has completed 10 years of participation.

     (vi)   QUALIFIED ESOP ELECTION PERIOD shall mean the first 90 days
            following the end of each Plan Year.

     14.03  PARTICIPATION IN ESOP

     Each Participant in the Thrift Plan who elects to have his or her Employer
Contributions invested in the Company Stock Fund will automatically become an
ESOP Participant in the ESOP. Each ESOP Participant will have his or her ESOP
Account held in the ESOP Trust Fund.

     14.04  EMPLOYER CONTRIBUTIONS

                                                                             111
<Page>

     Only Employer Contributions and dividends issued on Shares held in the ESOP
Trust Fund will be contributed to the ESOP.

     14.05  PURCHASE OF SHARES PURCHASES FOR ESOP TRUST FUND. The Trustee
shall regularly purchase Shares for the ESOP Trust Fund in accordance with a
non-discretionary purchasing program. Such purchases may be made on any
securities exchange where Shares are traded, in the over-the-counter market, or
in negotiated transactions, and may be on such terms as to price, delivery and
otherwise as the Trustee may determine to be in the best interests of the ESOP
Participants. Interest and other income received on assets held in the ESOP
Trust Fund shall be reinvested in the ESOP Trust Fund. All funds to be invested
shall be invested by the Trustee in one or more transactions promptly after
receipt by the Trustee, subject to any applicable requirement of law affecting
the timing or manner of such transactions. All brokerage commissions and other
direct expenses incurred by the Trustee in the purchase of sale of Shares under
the ESOP will be borne by the ESOP Account investing and/or trading in Shares.

     (b)    UNITS. The interests of an ESOP Participant in his or her ESOP
Account shall be measures in Units, the number and value of which shall be
determined daily.

                                                                             112
<Page>

     14.06  DIVIDENDS

     Beginning on and after the ESOP Effective Date, and for all Plan Years
thereafter, dividends received by the Trustee with respect to Shares allocated
to the ESOP Accounts, in accordance with the election of each ESOP Participant,
will be either paid in cash to the ESOP Participant as soon as practicable
following the declaration date but in any case not later than 90 days after the
close of the Plan Year in which the dividends are paid or applied by the Trustee
for the purchase of additional Shares.

     An ESOP Participant will be given a reasonable opportunity before a
dividend is paid or distributed to make the election. The ESOP Participant will
have a reasonable opportunity to change a dividend election at least annually.
If there is a change in the ESOP governing the manner in which the dividends are
paid or distributed to ESOP Participants, each ESOP Participant will be given a
reasonable opportunity to make an election under the new ESOP terms prior to the
date on which the first dividend subject to the new ESOP terms is paid or
distributed. An ESOP Participant who fails to make an election as to whether to
receive his or her dividend in cash or have such dividend reinvested will be
treated as if he or she elected to have his or her dividend reinvested until
such time that he or she makes an affirmation election for a distribution of the
dividend. If dividends are reinvested and applied to the purchase of additional
Shares, such purchases shall be made promptly after the receipt of each such
dividend. The Trustee shall purchase, in one or more transactions, the maximum
number of whole Shares obtainable at then prevailing prices, including brokerage
commissions and other reasonable expenses incurred in connection with such
purchases. Such purchases may be made on any securities exchange where Shares
are traded, in the over-the-counter market, or in negotiated transactions, and
may be on such terms as to price, delivery and otherwise as the Trustee may
determine to be in the best interest of the ESOP

                                                                             113
<Page>

Participants. The Trustee shall complete such purchases as soon as practical
after receipt of such dividends, having due regard for any applicable
requirements of law affecting the timing or manner of such purchases. The
additional Shares so purchased shall be allocated among the respective ESOP
Accounts of the Participants in proportion to the number of Shares in each ESOP
Account at the record date for the payment of the dividend so applied. Such
allocation shall be made as promptly as practicable but for purposes of
determining the time at which such additional Shares shall become distributable,
the additional Shares so allocated to each ESOP Participant's ESOP Account shall
be deemed to have been allocated as of the respective allocation dates of the
Shares in such ESOP Account at such record date, in proportion to the number of
such Shares previously allocated as of each such allocation date.

     14.07  VOTING RIGHTS, OPTIONS, RIGHTS, AND WARRANTS

     (a)    Each ESOP Participant is entitled to direct the Trustee as to the
manner in which any Shares or fractional Shares allocated to the ESOP
Participant's ESOP Account are to be voted. Any such Shares or fractional Share
for which the Participant does not give voting directions shall be voted by the
Trustee n the same manner and proportions as all other Shares held by the
Trustee for which voting directions are given by ESOP Participants.

     (b)    In the event that any option, right, or warrant shall be granted or
issued with respect to any Shares allocated to the ESOP Participant's ESOP
Account, each ESOP Participant shall be entitled to direct the Trustee whether
to exercise, sell, or deal with such option, right, or warrant.

     (c)    The Trustee shall keep confidential the ESOP Participant's voting
instructions and instructions as to any option, right or warrant and any
information regarding an ESOP

                                                                             114
<Page>

Participant's purchases, holdings and sales of Shares. The Plan Administrator
shall be responsible for monitoring the Trustee's performance of its
confidentiality obligations.

     14.08  TRANSFERABILITY

     A Participant may transfer all or any part of his or her existing ESOP
Account once a day to any other Investment Funds in the Trust Fund. Any election
will be made in such manner and on such conditions as may be prescribed by the
Plan Administrator and subject to any restrictions imposed on an Investment Fund
by the Trustee or Investment Manager.

     14.09  DIVERSIFICATION

     (a)    Each Qualified ESOP Participant shall have the right to elect to
diversify, by means of a distribution of whole ESOP Shares only, all or some
portion of the Diversifiable Amount in his ESOP Account during each of the six
consecutive Qualified ESOP Election Periods following the Plan Year in which
such Participant first became a Qualified ESOP Participant. The Diversifiable
ESOP Amount in the sixth Qualified ESOP Election Period for each Qualified ESOP
Participant shall be 50% of the number of Eligible ESOP Shares in his or her
ESOP Account as of the end of the preceding Plan Year. A distribution pursuant
to this must be a minimum of ten Shares, or all Whole Shares comprising the
Diversifiable ESOP Amount for such Qualified ESOP Election Period if less than
10. Each Qualified ESOP Participant who desires to elect diversification under
this Section shall, during the Qualified ESOP Election Period, complete and
execute a diversification election and consent form provided by his or her
Employer. Such election may be revoked or modified or a new election may be made
in its stead within the Qualified ESOP Election Period, upon the expiration of
which the diversification election shall be irrevocable.

     (b)    Diversification Procedure. The ESOP shall, within the 90-day period
following each Qualified ESOP Election Period, distribute to each Qualified ESOP
Participant who has

                                                                             115
<Page>

elected to diversify under this Section, the number of whole Shares which most
closely approximates, but does not exceed, the number of ESOP Shares duly
elected to be diversified by each such Qualified ESOP Participant. Failure by a
Qualified ESOP Participant to provide required consents to distribution of any
Diversifiable ESOP Amount, shall relieve the ESOP of all obligation to make any
such distribution.

     14.10  DISTRIBUTION OF SHARES

     (a)    An ESOP Participant's ESOP Account shall be available for
distribution to such ESOP Participant promptly after the earlier of the death,
disability or termination of employment of such ESOP Participant.

     (b)    If an ESOP Participant elects a distribution in Shares, certificates
for such Shares shall be delivered to the ESOP Participant as soon as
practicable after the effective date of the application.

     (c) In the case of death of an ESOP Participant, distributions in respect
of Shares allocated to his or her ESOP Account shall be made to his or her
Beneficiary. In the case of disability or termination of employment with the
Company or an Affiliate, distributions in respect of Shares allocated to the
ESOP Participant's ESOP Account shall be made unless the ESOP Participant elects
otherwise.

     (d)    All distributions from an ESOP Participant's ESOP Account shall be
made in Shares; provided, however, that an ESOP Participant or Beneficiary shall
have the right to elect, on a form furnished by and submitted to his or her
Employer, to receive a distribution, other than a distribution upon termination
of the ESOP, in cash. Except in the case of a final distribution from an ESOP
Participant's ESOP Account and a distribution of the entire ESOP Account
balance, all distributions from such ESOP Account made in Shares shall be made
in respect of whole Shares only, and any fractional Share which is otherwise
distributable shall

                                                                             116

be retained in such ESOP Account until it can be combined, in whole or in part,
with another fractional Share which shall subsequently become distributable, so
as to make up a whole Share. A final distribution from an ESOP Account (except a
distribution upon termination of the ESOP) shall be made in respect of the
number of whole Shares then remaining in the ESOP Account, together with a cash
payment in respect of any fractional Share based on the closing price of a Share
as reported on the New York Stock Exchange consolidated tape on the last trading
day of the month immediately preceding the month in which such final
distribution is made. The Trustee, in each such case, shall purchase such
fractional Share from the ESOP Participant at a price equal to the cash payment
to be made to the ESOP Participant.

     (e)    Whenever the Trustee requires funds for the purchase of fractional
Shares, such funds shall be drawn from the accumulated income of the ESOP Trust
Fund, if any, and otherwise shall be advanced by the Employer upon the Trustee's
request, subject to reimbursement from future income of the ESOP Trust Fund. All
fractional Shares so purchased by the Trustee shall be allocated to the ESOP
Accounts of the remaining Participants at such intervals as shall be determined
by the Plan Administrator, but no later than the end of the next succeeding Plan
Year. The Trustee shall sell any Shares in respect of which a cash distribution
is to be made. The Trustee may make such sales on any securities exchange where
Shares are traded, in the over-the-counter market, or in negotiated
transactions. Such sales may be on such terms as to price, delivery and
otherwise as the Trustee may determine to be in the best interests of the ESOP
Participants. The Trustee shall complete such sales as soon as practical under
the circumstances having due regard for any applicable requirements of law
affecting the timing or manner of such sales.

                                                                             117

     (f)    Upon any termination of the ESOP, the ESOP Trust Fund shall continue
until all Shares which have been allocated to ESOP Participants' ESOP Accounts
have been distributed to the ESOP Participants, unless the Board directs an
earlier termination of the ESOP Trust Fund. Upon the final distribution of
Shares, or at such earlier time as the Board shall have fixed for the
termination of the ESOP Trust Fund, the Plan Administrator shall direct the
Trustee to allocate to the ESOP Participants any Shares then held by the Trustee
and not yet allocated, and the Trustee shall distribute to the ESOP Participants
any whole Shares which have been allocated to their ESOP Accounts but which have
not been distributed, shall sell all fractional Shares and distribute the
proceeds to the respective ESOP Participants entitled to such fractional Shares,
shall liquidate any remaining assets (other than Shares) held by the ESOP Trust
Fund, and shall apply the proceeds of such liquidation and any remaining funds
held by the Trustee, the disposition of which is not otherwise provided for, to
a distribution to all ESOP Participants then receiving a final distribution of
Shares, in proportion to the whole and fractional Shares to which each is
entitled; and the ESOP Trust Fund shall thereupon terminate.

                                                                             118

     If upon establishment of a Term Rate Period or a Fixed Rate Period, as the
     case may be, the Remarketing Agent certifies to the Trustee, Bond Counsel
     and the Authority in writing that the foregoing schedule is not consistent
     with then-prevailing market conditions, the Authority at the request of the
     Company may revise the foregoing Initial Premium, Reductions in Premium and
     No-Call Periods without the approval of the Holders to reflect
     then-prevailing market conditions, upon receipt of an opinion of Bond
     Counsel to the effect that any revisions pursuant to this paragraph, either
     by itself or in conjunction with the establishment of a Calculation Period
     or a Fixed Rate, as the case may be, are made in accordance with this
     Indenture, is permitted under the Act and will not adversely affect the
     exclusion of interest on the Bonds from gross income for federal income tax
     purposes.
