                                  THE COMPANY

         The Company supplies electric and gas service in Nassau and Suffolk
Counties and to the Rockaway Peninsula in Queens County, all on Long Island,
New York.  The principal executive offices of the Company are located at 175
East Old Country Road, Hicksville, New York 11801 and the general telephone
number is (516) 755-6650.

         The Company's service territory covers an area of approximately 1,230
square miles.  The population of the service area, according to the Company's
1993 estimate, is approximately 2.7 million persons, reflecting a .14% increase
since the 1990 census.  This is a larger population than in each of 20 of the
50 states and includes approximately 98,000 persons who reside in Queens County
within the City of New York.  The area served is predominantly residential, but
the Company receives approximately one-half of its electric revenues from
commercial and industrial customers.  Although electronics and aerospace are
the largest manufacturing industries in the area, about 88% of total employment
is non-manufacturing.  Industrialization is gradually increasing in Suffolk
County which, with three times the land area, has only one-third the population
density of Nassau County.

         The percentages of total revenues and operating income before income
taxes derived from electric and gas operations for each of the last three years
ended December 31 are shown in the following table:

                               RATIOS OF EARNINGS

Ratio of Earnings to Fixed Charges

         The Company's ratios of earnings to fixed charges, including AFC and
RMC (as defined below), for each of the last five years ended December 31 were
as follows:

                             Year Ended December 31,    

<TABLE>
<CAPTION>
             1993      1992     1991      1990     1989
             ----      ----     ----      ----     ----
             <S>       <C>      <C>       <C>        <C>
             1.87      1.90     1.93      1.98       *
</TABLE>


         For purposes of computing the ratio of earnings to fixed charges for
rate-regulated public utilities, earnings represent principally net income
before the deduction of fixed charges and federal income taxes.  Fixed charges
during the period include an interest factor and an amortization factor.  The
interest factor includes the interest charges on long-term and short-term debt
and the portion of rentals deemed representative of the interest factor.  The
amortization factor includes the amortization of debt expenses and discounts or
premiums related to any indebtedness.

         Generally, the decrease in the ratio of earnings to fixed charges
since 1990 reflects many factors, including among others, decreases in the
Company's net income which have resulted from a lower allowed rate of return on
common equity and increases in total interest charges.

- ---------------
*   For the year ended December 31, 1989, earnings were inadequate to cover
    fixed charges.  To attain a one-to-one coverage, earnings were deficient by
    approximately $1.1 billion as a result of the Company having recorded in
    June 1989 the effects of two agreements:  (1) an agreement among the
    Company and the State of New York entered into in 1989 (the "1989
    Settlement") settling certain issues relating to the Company and providing,
    among other matters, for the transfer of the Shoreham Nuclear Power Station
    ("Shoreham") to the Long Island Power Authority, an entity of the State,
    and (2) an agreement among the Company, certain of its former officers and
    the class of ratepayers acting through counsel for the class entered into
    in 1989 (the "Class Settlement") settling a lawsuit brought against the
    Company under the federal Racketeer Influenced and Corrupt Organizations
    Act (the "RICO Act").  Had the Company computed the ratio of earnings to
    fixed charges without giving effect to the discontinuance of accruing
    Allowance for Funds used during Construction ("AFC") on Shoreham and the
    losses resulting from the 1989 Settlement  and the Class Settlement, the
    resulting ratio would have been 1.85.

Ratio of Earnings to Combined Fixed Charges and Preferred Stock Dividends

         The Company's ratio of earnings to combined fixed charges and
Preferred Stock dividends, including AFC and RMC (as defined below), for each
of the last five years ended December 31 were as follows:

<TABLE>
<CAPTION>

           1.61      1.59     1.60      1.64       *
</TABLE>


         For purposes of computing the ratio of earnings to combined fixed
charges and Preferred Stock dividends for rate-regulated public utilities,
earnings represent principally net income before the deduction of fixed charges
and federal income taxes.  Fixed charges during the period represent the
portion of rentals deemed representative of the interest factor, the interest
charges during the period on long-term and short-term debt and the amortization
of debt expenses and discounts or premiums related to any indebtedness.
Preferred Stock dividend requirements are computed by increasing Preferred
Stock dividends by an amount representing the pre-tax earnings which would be
required to cover such Preferred Stock dividend requirements.

- ---------------
*  For the year ended December 31, 1989, earnings were inadequate to cover
   combined fixed charges and Preferred Stock dividends.  To attain a
   one-to-one coverage, earnings were deficient by approximately $1.3 billion
   as a result of the Company having recorded in June 1989 the 1989 Settlement
   and the Class Settlement.  Had the Company computed the ratio of earnings to
   combined fixed charges and Preferred Stock dividends without giving effect
   to the discontinuance of accruing AFC on Shoreham and the losses resulting
   from the 1989 Settlement and the Class Settlement, the resulting ratio would
   have been 1.42.

Additional Information Concerning the Ratios of Earnings

         The Company's ratios of earnings reflect certain accounting and
regulatory aspects of the utility industry and the Company's experience with
Shoreham.

         Because of long-lead times in the construction of major capital
projects, utility ratemaking and accounting practices provide for the
recognition of AFC, a non-cash credit to income that represents the net cost of
borrowed funds for construction purposes and a reasonable rate of return upon a
utility's other funds when so used.  The amount of AFC fluctuates from period
to period with changes in the cost of money, the level of construction
activity, the amount of construction work in progress included in rate base and
modifications in regulatory policy and the effect of regulatory disallowances.
AFC is traditionally recovered from customers over the service life of the
project through revenues when the project is completed and included in rate
base.

         Generally accepted accounting principles ("GAAP") recognize that a
regulatory agency may take actions that create future economic benefits--the
essence of an asset--known as a regulatory asset.  In considering the rate
relief to be granted to the Company upon the effectiveness of the 1989
Settlement, the Public Service Commission of the State of New York (the "PSC")
created such a regulatory asset, the Financial Resource Asset (the "FRA"), to
provide the Company with sufficient cash flows to assure its financial
recovery.  The FRA is embodied in the Rate Moderation Agreement (the "RMA")
which is one of the constituent documents of the 1989 Settlement.

         The FRA consists of two components, the Base Financial Component (the
"BFC") and the Rate Moderation Component (the "RMC").  The RMA provides that
the Company amortize the BFC over a forty-year period beginning July 1, 1989
and permits a full return on the unamortized balance.  The BFC, as initially
established, represents the present value of the future net-after-tax cash
flows which were provided to the Company for its financial recovery and are
included in the Company's electric rates through an amortization over forty
years on a straight-line basis.  The RMC reflects the difference between the
Company's revenue requirements under conventional ratemaking and revenues
resulting from the implementation of the rate moderation plan provided in the
RMA.  This rate moderation plan is designed to hold electric rate increases to
the levels provided for in the RMA, subject to adjustments provided therein.
The Company's revenue requirements are those revenues needed to recover (i) the
rate of return allowed by the PSC and (ii) all other elements of its allowed
costs.

General and Refunding Bonds

         New Bonds and the G&R Mortgage

         General:  The New Bonds are to be issued under the General and
Refunding Indenture, dated as of June 1, 1975, between the Company and United
States Trust Company of New York, as Trustee (the "Trustee" or "G&R Trustee"),
as heretofore supplemented and amended and as hereinafter to be further





                                       7
<PAGE>   10
supplemented in connection with the sale of each series of New Bonds (the "G&R
Mortgage").  Chemical Bank is Authenticating Agent and Paying Agent for the New
Bonds.  All bonds (including the New Bonds) which may from time to time be
issued and outstanding under the G&R Mortgage are herein referred to as "G&R
Bonds."

         Form and Exchange:  Unless otherwise provided in a Prospectus
Supplement relating thereto, the New Bonds will be registered G&R Bonds,
without coupons, issuable in denominations of $1,000 and any integral multiple
thereof.  The New Bonds may be exchanged for other New Bonds of the same series
of different authorized denominations and may be transferred at Chemical Bank
without charge to the holders thereof other than for applicable taxes or other
governmental charges.

         Interest and Payment:  Unless otherwise provided in a Prospectus
Supplement relating thereto, checks for the payment of interest will be mailed
to the registered holders.  Principal is payable at the principal corporate
trust office of Chemical Bank located at 450 West 33rd Street, New York, New
York 10001.

         Redemption Provisions:  The New Bonds may not be redeemed prior to the
date set forth in the applicable Prospectus Supplement relating to a series of
New Bonds, except as set forth below under the heading "Extraordinary
Redemption."  On or after such date, the New Bonds of such series may be
redeemed, as a whole or in part, at any time or times, upon at least 30 days'
notice, upon payment of the relevant percentage of the principal amount so
redeemed set forth in the applicable Prospectus Supplement (1) under the
heading "Special Redemption Price" in case of redemption from cash deposited
pursuant to the provisions of the G&R Mortgage relating to either the Sinking
and Improvement Fund or the Maintenance Fund as required in the G&R Mortgage
and (2) under the heading "Regular Redemption Price" in case of any other
redemption at the option of the Company, together, in each case, with interest
accrued thereon to the redemption date.  For information  regarding the
circumstances under which cash may be deposited pursuant to the provisions
relating to the Sinking and Improvement Fund and the Maintenance Fund, see the
discussion below under the headings "Sinking and Improvement Fund" and
"Maintenance Fund," respectively.

         At the Company's election, any notice of redemption may provide that
it is subject to the deposit of the required redemption funds with the Trustee
before the date fixed for such redemption and will be of no effect if such
deposit is not made.

         Extraordinary Redemption:  The New Bonds may be redeemed at 100% of
their principal amount, together with interest accrued thereon to the
redemption date, upon at least 30 days' notice, as a whole, (i) at the
Company's election within 120 days of the acquisition date if all of the
Company's Common Stock is acquired by a governmental body or instrumentality,
or (ii) at any time that all or substantially all of the Company's property is
released from the lien of the G&R Mortgage.

<PAGE>   11
         Issuance of Additional G&R Bonds:  The G&R Mortgage provides that, so
long as the Company is not in default in the performance of any covenant to be
performed by it under the G&R Mortgage and obtains all requisite authorizations
of governmental bodies, it may issue additional G&R Bonds thereunder to the
extent of any one or more of the following:  (1) 60% of the Bondable Value of
Property Additions ("BVPA"); (2) the amount of Refundable Prior Lien Bonds
theretofore or then retired or deposited with the Trustee or the trustee under
a Prior Lien (including bonds, other than Pledged Bonds, issued under the
Company's Indenture of Mortgage and Deed of Trust dated as of September 1,
1951, as supplemented and as to be further supplemented (the "First
Mortgage")), as provided in the G&R Mortgage; (3) the amount of certain G&R
Bonds theretofore or then retired or (4) the amount of cash deposited with the
Trustee against the issuance of G&R Bonds.  Currently, for the reasons set
forth below, the Company is unable to issue G&R Bonds pursuant to (1) above.
However, based upon Refundable Prior Lien Bonds and retired G&R Bonds available
as a basis for issuance of New Bonds, as of December 31, 1993, the Company was
able to issue approximately $707 million of additional G&R Bonds.

         Generally, when issuing G&R Bonds, the Company must satisfy a mortgage
interest coverage requirement (the "G&R Mortgage Interest Coverage").  The G&R
Mortgage Interest Coverage requires that the Net Earnings available for
interest for any twelve consecutive calendar months within the fifteen
consecutive calendar months preceding the issuance of the G&R Bonds be equal to
at least two times the stated annual interest payable on the G&R Bonds to be
outstanding and on Prior Lien Bonds (other than Pledged Bonds) to be
outstanding.  Based upon earnings for the year ended December 31, 1993 and
after giving effect to the issuance of $707 million of New Bonds with an
assumed interest rate of 9% per annum, but without giving effect to the
redemption of any series of G&R Bonds or First Mortgage Bonds with the proceeds
of the New Bonds, the G&R Mortgage Interest Coverage would be 4.90.

         The Company is unable at this time to issue additional G&R Bonds
pursuant to (1) above.  When Property Additions are to be used as a basis for
the issuance of G&R Bonds, the G&R Mortgage requires recognition of any
depreciation, retirement or adjustment, such as the write-downs made pursuant
to the Financial Accounting Standards Board Statement of Financial Accounting
Standards ("SFAS") No. 90, Regulated Enterprises-Accounting for Abandonments
and Disallowances of Plant Costs and the retirement of Shoreham following the
effectiveness of the 1989 Settlement.  Although the Company has had Property
Additions since the effectiveness of the 1989 Settlement and expects to
continue to do so in the future, the write-downs associated with SFAS No. 90,
retirements and other adjustments in 1988 and the retirement of Shoreham in
1989 resulted in a "deficit" in the BVPA which, at December 31, 1993, was $202
million.  The existence of this deficit precludes the issuance of any G&R Bonds
on the basis of Property Additions at this time.  However, the deficit is
expected to be eliminated by the end of 1994 allowing the Company to issue G&R
Bonds again on the basis of Property Additions beginning in 1995.  There are no
other restrictions on the Company's ability to issue G&R Bonds on the basis of
Property Additions.





                                       9
<PAGE>   12
         Security and Priority:  The New Bonds are to be secured together with
all other G&R Bonds, whenever issued, by a lien on substantially all of the
Company's property.  Excluded from the lien of the G&R Mortgage are cash,
securities, contracts, accounts receivable, property owned by the Company
located outside the State of New York, products held for sale in the ordinary
course of business and all fuel (including nuclear fuel), materials and
supplies and other personal property which are consumable (otherwise than by
ordinary wear and tear) in their use in the operation of the plants of the
Company (unless and until such excepted property is expressly subjected by the
Company to the lien of the G&R Mortgage).  The lien of the G&R Mortgage is
subject to Excepted Encumbrances (including the lien of the First Mortgage) and
certain minor restrictions.  The G&R Mortgage contains provisions subjecting
after-acquired property to the lien thereof (subject to pre-existing liens)
except in the case of a consolidation or merger in connection with which
arrangements are made whereby no additional G&R Bonds are to be issued other
than for refunding purposes.

         The lien of the G&R Mortgage, which is currently subordinate to the
lien of the First Mortgage, will become the Company's most senior mortgage lien
upon the Company's properties in 1997, the year in which the last of the
currently outstanding bonds under the First Mortgage ("First Mortgage Bonds")
matures.  As of December 31, 1993, there were $1.7 billion of G&R Bonds
outstanding under the G&R Mortgage.  The aggregate principal amount of First
Mortgage Bonds outstanding at December 31, 1993, exclusive of Pledged Bonds,
was $125 million maturing at various dates through 1997.  At December 31, 1993,
the G&R Trustee held $1.0 billion of Pledged Bonds.  Pledged Bonds are First
Mortgage Bonds which have been deposited with the Trustee under the G&R
Mortgage as additional security for the payment of the obligations represented
by the G&R Bonds.  In connection with the issuance of the New Bonds, the
Company expects to issue, concurrently with the New Bonds, additional Pledged
Bonds.  No other material Prior Liens exist at present.  As the bonds currently
outstanding under the First Mortgage mature or are redeemed, such bonds will
represent a decreasing share of the security afforded by the lien of the First
Mortgage and to the extent that such bonds mature or are redeemed or additional
Pledged Bonds are issued, the Pledged Bonds will represent an increasing share
of the lien of the First Mortgage.  When all outstanding bonds issued under the
First Mortgage (other than the Pledged Bonds) have been purchased, redeemed or
have matured, the Pledged Bonds will be surrendered and the First Mortgage
discharged.

         Highly Leveraged Transaction Protection:  The provisions in the G&R
Mortgage affording debt holders some protection in the event of a highly
leveraged transaction are those described under this heading and under the
headings "New Bonds and the G&R Mortgage -- Redemption Provisions," "Issuance
of Additional G&R Bonds" and "Security and Priority."  In addition, in New York
State, the issuance of most debt securities, the acquisition by another
corporation of significant percentages of the corporate stock of a utility
company and generally the repurchase of a utility company's securities by that
company require the approval of the PSC.





                                       10
<PAGE>   13
         The G&R Mortgage provides that no merger or acquisition and no
transfer of all or substantially all of the Company's properties shall impair
the lien and security of the G&R Mortgage.  The G&R Mortgage requires any
successor to the Company to expressly assume the obligations to the holders of
G&R Bonds.  The provisions protecting the holders of G&R Bonds may be waived
only by those holders that are adversely affected.  The percentage of any vote
required to carry any direction, waiver or consent depends upon the issue being
voted on.  No proposal can be adopted with the vote of less than a majority of
the aggregate principal amount of outstanding G&R Bonds.

         Pledged Bonds:  The Company has agreed (except as indicated below)
that so long as any of the bonds now outstanding under the First Mortgage
remain outstanding, whenever it issues G&R Bonds (or withdraws, on the basis of
Property Additions, cash deposited with the Trustee which was the basis for the
authentication and delivery of G&R Bonds), it will also (to the extent
permitted by the terms of the First Mortgage, other than on the basis of the
deposit of cash, and applicable law and regulations) issue to and deposit or
pledge with the Trustee additional bonds under the First Mortgage to be held as
additional security for the G&R Bonds.  Other than these Pledged Bonds, the
Company will not issue any additional bonds under the First Mortgage.  Such
Pledged Bonds will be issued in a principal amount as near as may be equal to,
to the nearest $1,000,000 but not in excess of, the principal amount of G&R
Bonds then outstanding and then to be issued, less the principal amount of
Pledged Bonds then held by the Trustee.  Except during the continuance of a
Completed Default hereafter described, no payment by way of principal, interest
or otherwise shall be made on any of the Pledged Bonds, and at their respective
maturities they are to be canceled.  The G&R Mortgage provides that the Pledged
Bonds may not be sold by the Trustee.  The Trustee may exercise, in its
absolute discretion without the consent of the Company, any and all rights of a
bondholder with respect to the Pledged Bonds then held by the Trustee and
participate in any bondholder proceedings relating to the First Mortgage.

         All of the holders of the G&R Bonds share, equally and ratably, in the
benefits of the lien of the First Mortgage resulting from the issuance and
deposit of all Pledged Bonds.  The total principal amount of such Pledged Bonds
will vary from time to time, depending principally upon the ability of the
Company to meet the tests for issuance of additional bonds under the First
Mortgage.  Accordingly, the interest of the holders of G&R Bonds in the lien of
the First Mortgage through the Pledged Bonds may increase or decrease with each
new issue of G&R Bonds.  The deposit of Pledged Bonds with the Trustee as
described above does not increase the total amount of property in which holders
of G&R Bonds have a direct or indirect security interest since the G&R Mortgage
constitutes a junior lien on substantially the same property that is subject to
the first lien of the First Mortgage.

         The principal benefit to holders of G&R Bonds provided by the Pledged
Bonds is that the Pledged Bonds will provide such holders a means of
participating indirectly in the lien of the First Mortgage.  If, for example,
in the event of a reorganization or insolvency, values allocated to the





                                       11
<PAGE>   14
holders of bonds under both Mortgages were less than the principal amount of
and interest on bonds then outstanding under the First Mortgage, including the
Pledged Bonds, then the allocation to the holders of G&R Bonds would be
increased by reason of their participation with all other First Mortgage Bonds
through the Pledged Bonds, pari passu, in the lien of the First Mortgage.
Pledged Bonds issued and held by the G&R Trustee currently represent 89% of all
First Mortgage Bonds, including Pledged Bonds.  The issuance of Pledged Bonds
in connection with the issuance of G&R Bonds is largely dependent upon the
availability of Property Additions and the use of available Property Additions
and retired First Mortgage Bonds to satisfy the Depreciation Fund and Sinking
Fund requirements under the First Mortgage.

         For information respecting the amount of Pledged Bonds which the
Company is currently able to issue, see the discussion below under the heading
"Pledged Bonds and the First Mortgage -- Issuance of Pledged Bonds."

         Sinking and Improvement Fund:  The G&R Mortgage requires the Company
to make annual Sinking Fund deposits on or before June 30 of each year.  The
amount to be deposited is to be equal to 1% of the principal amount of any G&R
Bonds issued thereunder (except G&R Bonds issued against retired G&R Bonds, G&R
Bonds retired with certain cash held by the Trustee and G&R Bonds issued to
secure other indebtedness) and of outstanding bonds (other than Pledged Bonds)
issued under the First Mortgage, in each case as of December 31 of the prior
year.  Deposits are to be made in cash, reduced by credits elected by the
Company for (i) 60% of the BVPA, (ii) the principal amount of Refundable Prior
Lien Bonds and certain G&R Bonds previously issued and retired and (iii) cash
previously or concurrently deposited with the Trustee under the First Mortgage
pursuant to its Sinking Fund provisions and not withdrawn.  Cash deposited
under the G&R Mortgage pursuant to this requirement may, during the next
succeeding three years, be withdrawn upon the same basis that a credit may be
taken as set forth in (i) and (ii) above, or may be applied to the payment,
purchase or redemption of G&R Bonds, including G&R Bonds subject to a mandatory
Retirement Fund.  The 1993 Sinking Fund requirement, due on or before June 30,
1994, is expected to be approximately $24 million.

         Sinking Fund cash amounting to $100,000 or more which has been held by
the Trustee for more than three years must be applied to the retirement of G&R
Bonds.  Whenever cash held by the Trustee in the Sinking Fund is used by the
Trustee to purchase G&R Bonds and such G&R Bonds are purchased at less than the
principal amount thereof, an amount equal to the discount is to be paid to the
Company.

         Maintenance Fund:  The Maintenance Fund covenant under the G&R
Mortgage requires that the aggregate amount of Property Additions added
subsequent to December 31, 1974 must be, as of the end of each calendar year
subsequent to 1974, at least equal to the cumulative Provision for Depreciation
(as defined in the G&R Mortgage) from December 31, 1974.  The Company is
required to satisfy Maintenance Fund obligations through the deposit of cash
or, in lieu of such deposit, through certification of retired G&R Bonds or
retired First Mortgage Bonds, if Property Additions cumulative from December
31, 1974 do not





                                       12
<PAGE>   15
equal or exceed the cumulative Provision for Depreciation.  Currently, such
cumulative Property Additions exceed the cumulative Provision for Depreciation.
As of December 31, 1993, the amount of such cumulative Property Additions
calculated pursuant to the G&R Mortgage was approximately $9.4 billion,
including approximately $5.5 billion of Property Additions attributable to
Shoreham.  Also, as of December 31, 1993, the amount of the cumulative
Provision for Depreciation, similarly calculated, was approximately $1.4
billion.  The Company anticipates that the aggregate amount of cumulative
Property Additions will continue to exceed the cumulative Provision for
Depreciation and therefore deposits of cash or certifications of retired G&R
Bonds or retired First Mortgage Bonds will not be required to satisfy the
requirements of the Maintenance Fund.

         Modification or Amendment of the G&R Mortgage:  The rights of the
bondholders may be modified with the consent of the holders of 66-2/3% of the
principal amount of the G&R Bonds of all series affected.  Notwithstanding the
foregoing, no modification is effective against any bondholder without his
consent if such modification would (a) alter the terms of payment of principal,
premium, if any, or of interest, (b) permit creation of additional prior or
parity liens other than Excepted Encumbrances, (c) reduce the percentage of the
principal amount of G&R Bonds required for modification or (d) reduce
materially the bondholders' security by depriving them in any respect of the
lien of the G&R Mortgage.

         Default and Notice Thereof:  Completed Defaults include (a) default in
the payment of principal of and premium, if any, on any of the G&R Bonds, (b)
default for 30 days in payment of interest on any of the G&R Bonds, (c) default
in the payment of principal or interest continued beyond the period of grace on
any Prior Lien Bonds (except Pledged Bonds), (d) default under the First
Mortgage continued beyond the period of grace specified therein, (e)
bankruptcy, insolvency or reorganization (under certain circumstances) of the
Company, (f) default in the performance of the covenant with respect to merger
or consolidation and (g) default, for 60 days after notice, in the performance
of any other covenant, agreement or condition in the G&R Mortgage.  The holders
of 10% or more in principal amount of the outstanding G&R Bonds may give notice
of certain defaults.  Holders of not less than 25% in principal amount of
outstanding G&R Bonds or the Trustee may declare the principal of and accrued
interest on all outstanding G&R Bonds due upon the occurrence of a Completed
Default.  Under certain circumstances, including the curing of such Completed
Default, the holders of a majority in principal amount of the outstanding G&R
Bonds may annul any such declaration.

         Holders of not less than a majority in principal amount of G&R Bonds
may direct the Trustee as to the time, method and place of enforcing the lien
of the G&R Mortgage, but the Trustee may decline to follow such direction
should its responsible officers determine that the directed action would
involve the Trustee in personal liability or would be unjustly prejudicial to
the rights of non-assenting holders of G&R Bonds.





                                       13
<PAGE>   16
         The Trustee may require reasonable indemnification before being
required to enforce the lien of the G&R Mortgage.

         Evidence as to Compliance with the Mortgage Provisions:  On or before
June 30 of each year, certificates of Company Officers are required to be
furnished to the Trustee with respect to the BVPA and the absence of defaults
under the G&R Mortgage.

         Pledged Bonds and the First Mortgag

         General:  The G&R Mortgage prohibits the issuance of additional bonds
under the First Mortgage except as Pledged Bonds.  Upon the maturity on April
1, 1997 of the last series of non-pledged First Mortgage Bonds, the Company
will be able to remove the First Mortgage as a lien upon its properties and
will no longer be required to issue First Mortgage Bonds as Pledged Bonds.
Until that time, however, the Company anticipates that it will issue additional
Pledged Bonds concurrently with the issuance of each series of the New Bonds.
For a description of the circumstances under which additional Pledged Bonds of
the same and other series of First Mortgage Bonds are required to be issued and
a description of the new Pledged Bonds, see the discussion under the heading
"New Bonds and the G&R Mortgage -- Pledged Bonds" above and "Interest and
Payment" and "Issuance of Pledged Bonds" below, respectively.

         IBJ Schroder Bank & Trust Company is the trustee under the First
Mortgage.  Citibank, N.A. ("Citibank") is Paying Agent and Authenticating Agent
of the First Mortgage Bonds (including the Pledged Bonds).  Citibank, in
addition, provides the Company with depository and other normal banking
services (including participation in the Company's bank credit facilities).

         The statements herein concerning the First Mortgage, and the bonds
issued thereunder, do not purport to be complete and are qualified in their
entirety by express reference to the First Mortgage and to the definitions
therein of the terms used herein.  The particular terms of the Pledged Bonds
issued concurrently with the issuance of the New Bonds will be described in the
Prospectus Supplement relating to such Bonds.

         Interest and Payment:  In connection with the issuance of each series
of New Bonds, the Company will, as required by the G&R Mortgage and to the
extent permitted by the First Mortgage, issue First Mortgage Bonds to be
pledged with the G&R Trustee.  See the discussion under the heading "New Bonds
and the G&R Mortgage -- Pledged Bonds."  The Pledged Bonds, to be issued
pursuant to a supplemental indenture to the First Mortgage, will mature on the
date set forth in an applicable Prospectus Supplement and will bear interest at
the rate shown in their title until maturity.

         At a later date, the Company may issue and pledge additional First
Mortgage Bonds up to a principal amount equal to the principal amount of G&R
Bonds then outstanding.  In the event of default, the Pledged Bonds will bear
interest at the rate of 6% per annum thereafter.  However, the G&R Mortgage





                                       14
<PAGE>   17
provides that, except during the continuance of a Completed Default under the
G&R Mortgage, no payment by way of interest, principal or otherwise shall be
demanded or received on any Pledged Bonds.

         Issuance of Pledged Bonds:  Pledged Bonds may be issued (1) on the
basis of and in an amount up to 60% of Net Bondable Additions or (2) on the
basis of and in the amount of retired First Mortgage Bonds (initially issued on
the basis of Property Additions) only if Gross Income for twelve consecutive
months within the preceding fifteen months equals at least two times annual
interest charges on all bonds to be outstanding under the First Mortgage and
all prior lien obligations (the "First Mortgage Interest Coverage").  In this
calculation, the stated interest rate on Pledged Bonds is included even though
no interest is payable thereon except during the continuance of a Completed
Default under the G&R Mortgage.  Gross Income is the sum of Utility Operating
Income and Other Income.  Utility Operating Income is equal to the Company's
gross operating revenues less related expenses and deductions, taxes other than
income taxes and Minimum Depreciation.  Minimum Depreciation is the greater of
(a) the amount actually charged on the Company's books as a utility operating
revenue deduction for the preceding calendar year for depreciation, depletion,
obsolescence, retirements and amortization of the Company's Utility Plant
("Book Depreciation") or (b) an amount equal to (i) 15% of gross operating
revenues (less the cost of electricity and gas purchased for resale) from
Utility Plant for such year less (ii) the amount actually expended for
maintenance of Utility Plant used during such year ("Revenue Depreciation").
Other Income is equal to the Company's gross non-operating revenues less
related expenses and deductions, up to an amount not to exceed 5% of Utility
Operating Income.

         Based upon earnings for the year ended December 31, 1993, and after
giving effect to the Depreciation Fund and Sinking Fund requirements under the
First Mortgage, the Company will be able to issue concurrently with the
issuance of New Bonds approximately $234 million of Pledged Bonds with an
assumed average interest rate of 9% per annum.  However, the maximum amount of
First Mortgage Bonds that the Company will be able to issue as Pledged Bonds
concurrently with the New Bonds will depend upon the amount of Net Bondable
Additions and the amount of retired First Mortgage Bonds then available.

         Depreciation Fund:  The Depreciation Fund covenant of the First
Mortgage requires that the Company pay to the Trustee under the First Mortgage,
by June 30 of each year, cash (which may be withdrawn up to the amount of Gross
Bondable Additions and First Mortgage Bonds made the basis for such withdrawal)
equal to Minimum Depreciation which is described above.  Since the oil crisis
of the 1970s, Revenue Depreciation in each year has been greater than Book
Depreciation for such year.  Under the First Mortgage, the Company may satisfy
this requirement with cash or through the delivery of First Mortgage Bonds or
through the certification of retired First Mortgage Bonds or Gross Bondable
Additions.  Prior to the issuance in 1994 of any New Bonds, the Company intends
to satisfy the 1993 Depreciation Fund requirement with unused

Property Additions and retired First Mortgage Bonds.  The 1993 Depreciation
Fund requirement, due on or before June 30, 1994, is approximately $216
million.

         Assuming the Company's expenditures for capital improvements are
approximately $250 million annually, the Company expects that it will have
sufficient Property Additions and sufficient retired First Mortgage Bonds,
including Pledged Bonds, in 1995 and 1996, to satisfy the remaining annual
Depreciation Fund requirements under the First Mortgage.  If the Company is
required to deposit any cash on any June 30 to satisfy in part or in full the
Depreciation Fund or Sinking Fund requirements of the First Mortgage, the
Company expects that it will be able to withdraw all or substantially all of
such cash on the basis of Net Bondable Additions or retired First Mortgage 
Bonds.

         Sinking Fund:  The First Mortgage requires the Company to pay the
Trustee under the First Mortgage, by June 30 of each year, cash equal to 1% of
all previously issued First Mortgage Bonds (excluding bonds issued on the basis
of retired bonds).  The 1993 Sinking Fund requirement due on or before June 30,
1994 is estimated to be $18 million.  The annual Sinking Fund requirement will
increase upon the issuance of additional First Mortgage Bonds as Pledged Bonds
concurrently with the issuance of New Bonds.  Thereafter, the annual Sinking
Fund requirement is not expected to change unless, when additional G&R Bonds
are issued, additional First Mortgage Bonds to be pledged are issued on the
basis of Net Bondable Additions.  The Company expects that it will be able to
satisfy the remaining annual Sinking Fund requirements from its available
Property Additions and with retired First Mortgage Bonds which become available
through scheduled maturities.

         Security and Priority:  Bonds (including Pledged Bonds) issued or to
be issued under the First Mortgage are and will be secured by a direct first
lien on substantially all of the Company's properties (except cash, contracts,
accounts receivable and products held for sale or consumable in the ordinary
course of business), subject to Permitted Encumbrances and certain minor
restrictions.  The First Mortgage contains provisions subjecting after-acquired
property (subject to pre-existing liens) to the lien thereof.  There are no
securities or debt of senior rank (except those secured by Permitted
Encumbrances) and none of equal rank except bonds of other series outstanding
under the First Mortgage.

         Defaults and Notice Thereof:  Events of Default include default in the
payment of principal or satisfaction of any Sinking Fund obligation, default
for 30 days in payment of interest, default in performance of certain specified
covenants, default for 30 days after notice in performance of any other
covenant and certain events in bankruptcy, insolvency or reorganization.  The
Trustee is required to give bondholders notice of defaults known to it within
90 days of the occurrence thereof, unless remedied before the giving of such
notice.  The Trustee may withhold notice to bondholders of default (except in
payment of principal, interest or sinking or depreciation fund





                                       16
<PAGE>   19
obligations) if its responsible Officers think it in the interest of the
bondholders.  The holders of 25% in amount of the Bonds or the Trustee may
accelerate maturity upon an Event of Default, and the holders of 10% in amount
of the Bonds may give notice of certain defaults.  The holders of not less than
66-2/3% in principal amount of all Bonds of all series then outstanding
(excluding Bonds disqualified from participating) may on behalf of the holders
of all such Bonds waive any past default under the First Mortgage and its
consequences, except a default in the payment of the principal of, or premium
or interest on, any of the Bonds as and when the same shall become due by the
terms of such Bonds or upon a call for redemption.  The holders of a majority
in amount of the Bonds may require the Trustee to proceed to enforce the
Mortgage and, with certain exceptions, may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee.  The Company
is required to file annually with the Trustee a certificate as to existence or
nonexistence of defaults and as to compliance with certain terms of the
Mortgage.

Debentures

         New Debentures and the Debenture Indenture

         General:  The New Debentures are to be issued either under the
Indenture, dated as of November 1, 1986, between the Company and The
Connecticut Bank and Trust Company, National Association, (predecessor in
interest to State Street Bank and Trust Company), as Trustee, as supplemented,
or under the Indenture, dated as of November 1, 1992, between the Company and
Chemical Bank, as Trustee, as supplemented.  Both indentures are herein
referred to individually or collectively, as the case may be, as the "Debenture
Indenture."  Likewise, State Street Bank and Trust Company and Chemical Bank
are herein referred to individually or collectively, as the case may be, as the
"Trustee."  All debentures, including the New Debentures, which may from time
to time be issued and outstanding under the Debenture Indenture are herein
sometimes referred to as "Debentures."

         The Debenture Indenture does not limit the amount of Debentures which
may be issued thereunder and provides that Debentures may be issued thereunder
up to the aggregate principal amount which may be authorized from time to time.
The New Debentures may be issued from time to time in one or more series.  The
New Debentures will be unsecured obligations of the Company and will rank on a
parity with all other unsecured and unsubordinated indebtedness of the Company.

         The New Debentures will be subordinate to the indebtedness outstanding
under the Company's two mortgages, each of which is a lien on substantially all
of the Company's properties, and to the indebtedness under the Company's
Revolving Credit Agreement, dated as of June 27, 1989, as amended (the "1989
Credit Agreement"), which is secured by a first lien on the Company's accounts
receivable and fuel oil inventory.





                                       17
<PAGE>   20
         The Company's senior mortgage is its First Mortgage.  The lien of the
G&R Mortgage is subordinate to the lien of the First Mortgage.  For a
description of the G&R Mortgage and the First Mortgage, see the discussion
above under the headings "New Bonds and the G&R Mortgage -- Security and
Priority" and "Pledged Bonds and the First Mortgage -- Security and Priority."
G&R Bonds are currently the only debt senior to the New Debentures which the
Company may issue.  See "New Bonds and the G&R Mortgage -- Issuance of
Additional G&R Bonds."

         In addition, the Company currently has outstanding $3.7 billion of
unsecured debt (including $2.9 billion of Debentures, and $817 million of
Electric Facilities Revenue Bonds, Pollution Control Revenue Bonds and
Industrial Development Revenue Bonds) with which all of the Company's
debentures, including the New Debentures, rank pari passu.

         Form and Exchange:  Unless otherwise provided in a Prospectus
Supplement relating thereto, the New Debentures will be issued only in fully
registered form, without coupons, in denominations of $1,000 and any integral
multiple thereof.  The New Debentures may be presented for exchange or transfer
at the corporate trust office of the Trustee.  No service charge will be made
for any transfer or exchange of the New Debentures, but the Company may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

         Interest and Payment:  Unless otherwise provided in a Prospectus
Supplement relating thereto, checks for the payment of interest will be mailed
to the registered holders.  Principal and premium, if any, will be payable at
the principal corporate trust office of the Trustee.

         Modification of the Debenture Indenture:  The Debenture Indenture and
the rights of the holders may be modified or amended by the Company with the
consent of the holders of not less than 66-2/3% in principal amount of
Outstanding Debentures of all series affected by the modification (voting as a
class).  Notwithstanding the foregoing, no modification or amendment altering
the terms of payment of principal, premium, if any, or interest, changing the
place or medium of payment of principal, premium, if any, or interest,
impairing the rights of holders to institute suit for payment or reducing the
percentage required for certain modifications or waivers will be effective
against any holder without his consent.  Under certain circumstances, the
Debenture Indenture may be modified without the consent of the holders.

         Merger and Consolidation:  The Debenture Indenture provides that the
Company may, without the consent of the holders of Debentures, consolidate with
or merge into any other corporation or convey, transfer or lease its assets
substantially as an entirety to any person, permit any person to consolidate
with or merge into the Company or acquire or lease the assets of any person
substantially as an entirety, provided that (i) the successor corporation (if
not the Company) shall be a domestic corporation and shall assume by a
supplemental indenture the Company's obligations under the Debenture Indenture,
(ii) immediately after giving effect to the transaction,





                                       18
<PAGE>   21
no Event of Default (as defined below), and no event which, after notice or
lapse of time or both, would become an Event of Default shall have occurred and
be continuing and (iii) certain other conditions shall have been met.  Upon
compliance with these provisions by a successor corporation, except in the case
of a lease, the Company will be relieved of its obligations under the Debenture
Indenture.

         Highly Leveraged Transaction Protection:  Unless otherwise indicated
in a Prospectus Supplement, certain of the covenants described herein would not
necessarily afford debt holders protection in the event of a highly leveraged
transaction involving the Company.  However, in New York State, the issuance of
most debt securities, the acquisition by another corporation of significant
percentages of the corporate stock of a utility company and generally the
repurchase of a utility company's securities by that company require the
approval of the PSC.

         Events of Default:  The Debenture Indenture defines an Event of
Default with respect to the Debentures of any series as being any one of the
following events:  (a) default for 30 days in any payment of interest on that
series when due, (b) default in any payment of principal (or premium, if any)
on that series when due, (c) default in any payment of any sinking fund
installment on that series when due, (d) default for 60 days after the
appropriate notice in the performance of any other covenant in the Debentures
of that series or in the Debenture Indenture (other than a covenant included in
the Debenture Indenture solely for the benefit of any series of Debentures
other than that series), (e) default under any indebtedness for money borrowed
by the Company resulting in such indebtedness becoming due prior to maturity,
without such acceleration having been rescinded within 10 days after due notice
of such default as provided in the Debenture Indenture, (f) certain events in
bankruptcy, insolvency or reorganization of the Company or (g) any other Event
of Default provided with respect to Debentures of such series.  In case an
Event of Default shall occur and be continuing with respect to the Debentures
of any series, the Trustee or the holders of not less than 25% in aggregate
principal amount of the Debentures then outstanding of that series may declare
the principal of the Debentures of such series (or, if the Debentures of that
series were issued as discounted Debentures, such portion of the principal as
may be specified in the terms of that series) to be due and payable.  Any Event
of Default with respect to the Debentures of any series which has been cured
may be waived by the holders of a majority in aggregate principal amount of the
Debentures of that series then outstanding.

         The Debenture Indenture requires the Company to file annually with the
Trustee a written statement signed by an Officer of the Company as to
compliance with all conditions and covenants under the Debenture Indenture.
The Debenture Indenture provides that the Trustee may withhold notice to the
holders of any default (except in payment of principal or premium, if any, or
interest or in payment of any sinking fund installment) if it considers it in
the interest of the holders to do so.





                                       19
<PAGE>   22
         Subject to the provisions of the Debenture Indenture relating to the
duties of the Trustee in case an Event of Default shall occur and be
continuing, the Debenture Indenture provides that the Trustee shall be under no
obligation to exercise any of its rights or powers under the Debenture
Indenture at the request, order or direction of holders unless such holders
shall have offered to the Trustee reasonable indemnity.  Subject to such
provisions for indemnification and certain other rights of the Trustee, the
Debenture Indenture provides that the holders of a majority in principal amount
of the Debentures of any series then outstanding shall have the right to direct
the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on the
Trustee.

         Defeasance Provisions:  If, among other things, the Company deposits
irrevocably with the Trustee, in trust specifically for the benefit of the
holders of Debentures of a particular series, money and/or U.S. Governmental
Obligations which through the payment of interest thereon and principal thereof
in accordance with their terms will provide money in an amount sufficient to
pay (a) all of the principal of, premium, if any, and interest on the
Debentures of such series on the dates such payments are due in accordance with
the terms of such Debentures through their maturity or earlier redemption date
and upon satisfaction of certain other conditions set forth in the Debenture
Indenture, and (b) any mandatory sinking fund payments applicable to the
Debentures of such series on the day on which such payments are due and payable
in accordance with the terms of the Debenture Indenture and of the Debentures
of such series; at the Company's option, either:  (i) the Company will be
discharged from any and all obligations in respect of such series of Debentures
or (ii) the Company will cease to be under any obligation to comply with
certain restrictive covenants contained in the Debenture Indenture.  To
exercise any such option, the Company is required to meet certain conditions,
including delivering to the Trustee an opinion of counsel to the effect that
the Company has received from or there has been published by the Internal
Revenue Service a ruling to the effect that the deposit and related defeasance
would not cause the holders of the Debentures to recognize income, gain or loss
for federal income tax purposes as a result of such deposit, defeasance and
discharge.

         If the Company elects to defease a series of Debentures pursuant to
its option (i) described above, it is possible that holders would be required
for federal income tax purposes to treat the defeasance as a taxable exchange
of that series of Debentures for interests in the trust, notwithstanding the
opinion of counsel.  In that event, (1) a holder would recognize gain or loss
upon the defeasance in an amount equal to the difference between the holder's
tax basis for the holder's defeased Debentures and the value of the holder's
interest in the trust and (2) the trust should be treated as a trust for
federal income tax purposes, in which case each holder would report its
proportionate share of the income, gains, deductions and losses of the trust.
Purchasers of the New Debentures should consult their own advisers with





                                       20
<PAGE>   23
respect to the tax consequences to them of such deposit and discharge,
including the applicability and effect of tax laws of taxing jurisdictions
other than the United States Government.

         Relationship with Trustee:  Chemical Bank, or its affiliates, is a
potential lender under the Company's Revolving Credit Agreement and
participates on a regular basis in various general financing and banking
transactions for the Company.

Equity Securities

         For the year 1992, the Company reported to its shareowners that 100%
of Common Stock dividends and 100% of Preferred Stock dividends were to be
treated as a return of capital rather than ordinary income.  However, for the
year 1993 the Company reported to its shareowners that 100% of Common Stock
dividends and 100% of Preferred Stock dividends were to be treated as ordinary
income rather than return of capital.  Whether or not any portion of the
dividends, if any, in future years will constitute a return of capital or
taxable gain and, therefore, not be treated as ordinary dividend income is
dependent upon the current and accumulated earnings and profits of the Company
and the shareowner's tax basis for his shares.  Whether the Company has current
or accumulated earnings and profits will depend upon a number of factors
including, but not limited to, the net operating loss carryforward, future rate
relief, the resultant earnings of the Company, the size of the Company's
construction program and changes in income tax laws.  Furthermore, earnings and
profits are attributable to Preferred Stock dividends before they are
attributable to Common Stock dividends.  The calculation to determine the
amount of dividends considered a return of capital is subject to audit by the
Internal Revenue Service.

Preferred Stock

         General:  The Company is authorized to issue 7,000,000 shares of $100
Par Value Preferred Stock and 30,000,000 shares of $25 Par Value Preferred
Stock, issuable in series, each with such serial designation, dividend rate,
redemption prices, sinking fund provisions and conversion privileges as the
Board of Directors may by resolution fix and determine prior to issuance of a
particular series.  At December 31, 1993, 1,515,375 shares of $100 Par Value
Preferred Stock were issued and outstanding.  At that date, 22,658,000 shares
of $25 Par Value Preferred Stock were issued and outstanding.  Any shares of
Preferred Stock that are redeemed, converted or otherwise acquired by the
Company, including shares of Preferred Stock redeemed with the proceeds of the
New Preferred Stock and shares of Preferred Stock held as treasury shares that
will be used to satisfy the requirements of sinking funds, may be restored to
the status of authorized but unissued shares.

         The New Preferred Stock will be fully paid and nonassessable and will
have no preemptive rights.  Each series of the New Preferred Stock will rank on
a parity with each other series of Preferred Stock as to receipt of





                                       21
<PAGE>   24
dividends and liquidating distributions.  The rights of the holders of each
series of New Preferred Stock will be subordinate to those of the Company's
general creditors.

         Issuance of Additional Preferred Stock:  The Certificate of
Incorporation provides that the Company may issue Preferred Stock if, for any
twelve consecutive calendar months within the fifteen calendar months
immediately preceding the calendar month within which such additional shares
are to be issued, the net earnings of the Company available for the payment of
interest charges on its interest-bearing debt, determined after provision for
depreciation and all taxes and in accordance with sound accounting practice,
shall have been at least 1.5 times the aggregate of the annual interest charges
on the interest-bearing debt of the Company and annual dividend requirements on
all shares of, or ranking on a parity with, Preferred Stock to be outstanding
immediately after the proposed issue of such shares of, or ranking on a parity
with, the Preferred Stock (the "Earnings Ratio").  When interest-bearing
indebtedness or shares of Preferred Stock are to be retired with the proceeds
of a new series of Preferred Stock, there shall be excluded from the
computation of the Earnings Ratio the interest charges on such interest-bearing
indebtedness and the annual dividend requirements on such shares of Preferred
Stock.  Currently, the Company cannot meet the Earning Ratio and therefore is
unable to issue any Preferred Stock at this time except as indicated in the
following two sentences.  When the Earnings Ratio cannot be met, the
Certificate of Incorporation permits Preferred Stock to be issued in connection
with the purchase, redemption or other acquisition of outstanding Preferred
Stock if the aggregate annual dividend requirement and the aggregate amount
payable in a voluntary liquidation of the Preferred Stock to be issued do not
exceed the respective amounts for the Preferred Stock which is to be purchased,
redeemed or otherwise acquired.  Preferred Stock may also be issued beyond
amounts permitted under the Earnings Ratio with the approval of at least
two-thirds of the votes entitled to be cast by the holders of the total number
of shares of outstanding Preferred Stock.

         Dividend Rights:  The Company's ability to pay dividends on its
Preferred Stock is dependent upon, among other factors, action by the Company's
Board of Directors, the Company's financial condition, its ability to comply
with provisions of the Certificate of Incorporation and the availability of
retained earnings, future earnings and cash.  Dividends on each series of the
New Preferred Stock will be payable quarterly at the annual rate set forth in
their title, accruing from the date of original issue, on the dates set forth
in the Prospectus Supplement relating to such series of New Preferred Stock.
Dividends on the shares of all series of Preferred Stock are cumulative,
payable in cash, when and if declared by the Board of Directors out of funds
legally available therefor, in preference to dividends on the Common Stock or
any other stock ranking junior to the Preferred Stock.  If stated dividends are
not paid in full, the shares of all series of Preferred Stock share ratably in
the payment of dividends.  The Company's First Mortgage restricts dividends and
other distributions on, and certain purchases and redemptions of, capital stock
to an amount no greater than Net Income (as defined therein) since June 30,
1950.





                                       22
<PAGE>   25
         Conversion Rights:  The New Preferred Stock will not have any
conversion rights.  The only outstanding series of Preferred Stock which has
conversion rights is the Series I Convertible Preferred Stock.

         Liquidation Rights:  Unless otherwise set forth in the applicable
Prospectus Supplement, upon voluntary dissolution, liquidation or winding up of
the Company, the holders of the New Preferred Stock are entitled to receive an
amount equal to the applicable optional redemption price of each share plus
accrued dividends.  Upon involuntary dissolution, liquidation or winding up of
the Company, the holders of the New Preferred Stock are entitled to receive an
amount equal to the par value of each share plus accrued dividends, in either
case in preference to any stock ranking junior to it.  If amounts payable on
either voluntary or involuntary liquidation are not paid in full, the shares of
all series of Preferred Stock share ratably in any distribution of assets.

         Optional Redemption:  Unless otherwise set forth in the applicable
Prospectus Supplement, the New Preferred Stock will be redeemable at the
optional redemption price or prices and on the date or dates set forth in the
applicable Prospectus Supplement, plus, in each case, accrued dividends to the
date of redemption, on not less than 30 nor more than 60 days' notice.  If less
than all of the shares of any series of the New Preferred Stock are to be
redeemed, the shares to be redeemed shall be selected pro rata among the
holders thereof or by lot, as determined by the Company's Board of Directors.

         At the option of the Company, the Preferred Stock of all currently
outstanding series may be redeemed or refunded at any time, in whole or in part
(except that the Series L, R, AA, CC, GG, NN, QQ and UU Preferred Stock are
subject to certain restrictions regarding redemption).  The Certificate of
Incorporation and existing law do not restrict the redemption or purchase of
Preferred Stock by reason of any default in dividends, except for the
provisions mentioned above requiring ratable dividend and liquidation payments
on Preferred Stock, and except that no partial redemption of Series L, R, NN
and UU Preferred Stock may be made unless full cumulative dividends on such
series of Preferred Stock have been paid or declared and set apart for payment.

         Restrictions on Payments on Junior Stock and Sinking Fund Payments on
Other Stock:  The Company may not declare or pay any dividend on, or make any
other payment or distribution in respect of, the Company's Common Stock or any
other stock ranking junior to the Preferred Stock, unless full cumulative
required sinking fund redemptions of the Preferred Stock have been made.  No
redemptions or purchases of shares of any other series of Preferred Stock or
other shares ranking on a parity with the New Preferred Stock may be made
pursuant to any sinking or analogous fund requirement if any required
redemption of the New Preferred Stock is in arrears unless the redemptions or
purchases of the New Preferred Stock and such other shares are made pro rata
according to the amounts in arrears in redemptions or purchases required for
the respective requirements.





                                       23
<PAGE>   26
         The only series of previously issued Preferred Stock entitled to a
sinking fund are the Series L, R, NN and UU Preferred Stock.

         Voting Rights:  Except as indicated below or provided by applicable
law, holders of Preferred Stock have no voting rights.

         The consent of two-thirds of the votes entitled to be cast by holders
of the outstanding Preferred Stock is required for (a) amending the Certificate
of Incorporation in a manner adversely affecting the Preferred Stock otherwise
than by increasing the authorized number of shares thereof, but, if less than
all the series of Preferred Stock are affected, only the consent of two- thirds
of the votes entitled to be cast by holders of shares of all affected series is
required; (b) creating any class of stock, or securities convertible into
shares of stock, senior to the Preferred Stock or (c) with certain exceptions,
issuing any shares of, or ranking on a parity with, the Preferred Stock unless
the Earnings Ratio is met.

         The consent of a majority of the votes entitled to be cast by holders
of the outstanding Preferred Stock is required to (1) sell, lease, exchange,
assign, transfer or convey all or substantially all the property or business of
the Company or, unless the status and preferences of the Preferred Stock
survive, to merge or consolidate into or with any other company or (2) increase
the authorized number of shares thereof.

         If and when any four quarterly dividends on any Preferred Stock are in
default, and until all dividends in default have been paid or declared and set
aside for payment, the holders of the Preferred Stock are entitled, as a class,
to elect the smallest number of Directors constituting a majority of the full
Board of Directors.  The terms of office of all persons who may be Directors of
the Company will terminate upon the election of a majority of the Board of
Directors by the holders of the Preferred Stock and the holders of the
Company's Common Stock will have the right to elect the remaining Directors of
the Company.  If and when all dividends then in default on the shares of
Preferred Stock then outstanding shall be paid or declared and set aside for
payment, the right of the holders of the Preferred Stock to elect Directors
will terminate, subject to the future vesting of such right if dividends on any
shares of Preferred Stock are in default as set forth above.  Upon the
termination of any such special voting right, the terms of the Directors
elected by the holders of the Preferred Stock will terminate and the resulting
vacancies will be filled by the vote of a majority of the remaining Directors.

         Whenever holders of Preferred Stock vote as a class, the holders of
the $100 Par Value Preferred Stock are entitled to one vote for each share held
and the holders of the $25 Par Value Preferred Stock are entitled to
one-quarter of one vote for each share held.

         Income Tax:  Dividends on the New Preferred Stock will be eligible for
the dividends-received deduction afforded to corporate holders by Section 243
of the Internal Revenue Code as presently in effect, to the extent that the





                                       24
<PAGE>   27
dividends are paid from the "current or accumulated earnings and profits" of
the Company for federal income tax purposes.  For additional income tax
information, see the previous discussion under the heading "Equity Securities".

         Transfer Agent and Registrar:  The transfer agent and registrar for
the New Preferred Stock will be The Bank of New York, Shareholder Services
Dept., 11th Floor, 101 Barclay Street, New York, New York 10286-1258.

Common Stock

         General:  The Company is presently authorized under the Certificate of
Incorporation to issue 150,000,000 shares of Common Stock.  Of those authorized
shares, 112,332,490 shares of Common Stock were issued and outstanding at
December 31, 1993.

         Dividends:  The Company has paid dividends on its Common Stock in each
quarter beginning October 1, 1989.  Dividends per share declared on the Common
Stock during the last five years were as follows:

<TABLE>
<CAPTION>
                            1993       1992       1991       1990      1989

</TABLE>

         Although the Company contemplates the continuation of quarterly
dividend payments, the payment of future dividends is dependent upon, among
other factors, action by the Company's Board of Directors, the Company's
financial condition, future earnings and the availability of cash.

         Dividend Limitations:  No dividends may be declared on Common Stock
unless all past and current dividends on outstanding Preferred Stock and
Preference Stock have been paid or declared and set apart for payment and all
requisite sinking fund redemptions have been made on the Series L, R, NN and UU
Preferred Stock.  There are presently no shares of Preference Stock
outstanding.  Other Common Stock dividend limitations contained in the First
Mortgage securing the First Mortgage Bonds are not material.

         For information regarding the treatment for federal income tax
purposes of dividends either as ordinary income or return of capital, see the
discussion above under the heading "Description of the Securities -- Equity
Securities."

         Voting Rights:  Ordinarily, the holders of the Company's Common Stock
have sole voting power to elect Directors based on the cumulative voting
method.  The Company's Certificate of Incorporation provides, however, that
when dividends payable on any series of Preferred Stock shall be in default in
an amount equivalent to or exceeding four full quarterly dividends, the holders
of shares of Preferred Stock, voting separately as a class and regardless of
series, are entitled to elect at a Special Meeting called upon demand of a
holder of Preferred Stock and at each Annual Meeting thereafter





                                       25

until Preferred Stock dividends are paid or declared and funds set aside for
payment, the smallest number of Directors necessary to constitute a majority of
the full Board of Directors.  For a further discussion of voting rights of
holders of Preferred Stock, see "Description of the Securities -- Preferred
Stock Voting Rights."

         In addition, the assent of varying proportions of the votes which the
holders of the Preference Stock are entitled, as a class, to elect two
Directors to the Board of Directors, which right does not terminate until full
dividends have been provided for all past periods and for the current period.
In addition, the assent of varying proportions of the votes which the holders
of shares of Preference Stock are entitled to cast is required for certain
action: (i) two-thirds to amend the Certificate of Incorporation adversely to
the Preference Stock; (ii) two-thirds to create a class of shares or securities
convertible into shares senior to Preference Stock and (iii) a majority to
increase the authorized number of shares of Preference Stock.  None of the
7,500,000 authorized shares of Preference Stock are outstanding.

         Preemptive Rights:  Holders of the Company's Common Stock do not have
preemptive rights to purchase additional shares of Common Stock or securities
convertible into such shares.  From time to time, however, the Company may, at
its option, offer shares of Common Stock in a rights offering so that
shareowners may purchase additional shares of Common Stock in amounts
proportionate to their holdings.

         Other Rights:  In the event of liquidation, the holders of the Common
Stock are entitled to all assets that remain after satisfaction of creditors
and the liquidation preferences of outstanding Preferred Stock and, if any,
outstanding Preference Stock.  The outstanding shares of Common Stock are, and
the additional shares of Common Stock which may be offered hereby upon issuance
will be, fully paid and non-assessable.

         The number, designation, relative rights, preferences and limitations
of the shares of the Preferred Stock (including the adjustment provisions of
the Convertible Preferred Stock), of the Preference Stock, if any, and of the
Common Stock of the Company are stated in full in the Company's Certificate of
Incorporation.

         Transfer Agent and Registrar:  Unless otherwise provided in a
Prospectus Supplement relating thereto, the transfer agent and registrar for
the Common Stock is The Bank of New York, Shareholder Services Dept., 11th
Floor, 101 Barclay Street, New York, New York 10286-1258.

Annual Report on Form 10-K for the year ended December 31, 1993 have been
audited by Ernst & Young, Independent Auditors, as set forth in their report
thereon included therein and incorporated herein by reference.  Such financial
statements are incorporated herein by reference in reliance upon such report

                              PLAN OF DISTRIBUTION

         The Securities will be sold through underwriters, including Lehman
Brothers Inc., pursuant to one or more Underwriting Agreements.

         Each Underwriting Agreement will provide that the obligations of the
Underwriters are subject to certain conditions precedent, and that the
Underwriters will be obligated to purchase all of the Securities offered by any
Prospectus Supplement if any of the Securities are purchased, provided that
under certain circumstances involving defaults of one or more of the
Underwriters which aggregate in excess of ten percent of the aggregate
principal amount or the number of shares of such Securities, the Company may
either terminate such Underwriting Agreement or require each non-defaulting
Underwriter to purchase the amount of Debt Securities or the number of shares
of Equity Securities set forth in such Prospectus Supplement plus an amount
equal to one-ninth thereof, in which case less than all of the Securities may
be sold.

         The Company has been advised that the several Underwriters propose
initially to offer the Securities to the public at the public offering price
set forth on the cover page of the applicable Prospectus Supplement, and to
certain dealers at such price less a concession to be set forth in such
Prospectus Supplement.  Underwriters may allow, and such dealers may re-allow,
a concession to be set forth in such Prospectus Supplement to certain other
dealers.  After the initial public offering of the Securities, the public
offering price and concessions may be changed.

         Each Underwriting Agreement will provide that the Company indemnify
the several Underwriters against certain civil liabilities including
liabilities arising under the Securities Act of 1933, as amended.

         Lehman Brothers Inc. has served as managing underwriter for public
offerings of securities of the Company on numerous occasions since 1981.  In
addition, during the past seven years such firm has performed financial
advisory services for the Company, including acting as its financial advisor in
the 1988 and 1989 Settlements, and has served as Remarketing Agent of certain
long-term tax-exempt securities of the New York State Energy Research and
Development Authority, the proceeds of which have been used for Company
projects.

Item 15.         Indemnification of Directors and Officers.

         Sections 721-726 of Article 7 of the BCL provide for the
indemnification and advancement of expenses to officers and directors.  Section
721 provides that indemnification and advancement pursuant to the BCL are not
exclusive of any other rights an officer or director may be entitled to,
provided that no indemnification may be made to or on behalf of any director or
officer if a judgment or other final adjudication adverse to the director or
officer establishes that his acts were committed in bad faith or were the
result of active and deliberate dishonesty and were material to the cause of
action so adjudicated, or that he personally gained in fact a financial profit
or other advantage to which he was not legally entitled.  Section 722 provides
that a corporation may indemnify an officer or director, in the case of third
party actions, against judgments, fines, amounts paid in settlement and
reasonable expenses and, in the case of derivative actions, against amounts
paid in settlement and reasonable expenses, provided that the director or
officer acted in good faith, for a purpose which he reasonably believed to be
in the best interests of the corporation and, in the case of criminal actions,
had no reasonable cause to believe his conduct was unlawful.  In addition,
statutory indemnification may not be provided in derivative actions (i) which
are settled or otherwise disposed of or (ii) in which the director or officer
is adjudged liable to the corporation, unless and only to the extent a court
determines that the person is fairly and reasonably entitled to indemnity.
Section 723 provides that statutory indemnification is mandatory where the
director or officer has been successful, on the merits or otherwise, in the
defense of a civil or criminal action or proceeding.  Section 723 also provides
that expenses of defending a civil or criminal action or proceeding





                                      II-1
<PAGE>   32
may be advanced by the corporation upon receipt of an undertaking to repay them
if and to the extent the recipient is ultimately found not to be entitled to
indemnification.  Section 725 provides for repayment of such expenses when the
recipient is ultimately found not to be entitled to indemnification.  Section
726 provides that a corporation may obtain indemnification insurance
indemnifying itself and its directors and officers.  The Company has in effect
insurance policies providing both directors and officers liability coverage and
corporate reimbursement coverage.

         Section 402(b) of the BCL provides that a corporation may include in
its certificate of incorporation a provision limiting or eliminating, with
certain exceptions, the personal liability of directors to a corporation or its
shareowners for damages for any breach of duty in such capacity.  The
shareowners approved an amendment to the Company's Certificate of Incorporation
eliminating the personal liability of Directors to the extent permitted by New
York law.

         The Company's By-laws provide generally that the Company shall, except
to the extent expressly prohibited by the BCL, indemnify each of its officers
and directors made or threatened to be made a party to any action or
proceeding, whether civil or criminal, by reason of the fact that such person
is or was a director or officer of the Company against judgments, fines,
penalties, amounts paid in settlement and reasonable expenses, including
attorney's fees, incurred in connection with such action or proceeding, or any
appeal therein.  The Company's By-laws further provide for advancement and
reimbursement of such expenses incurred by an officer or director in defending
any action or proceeding in advance of the final disposition thereof upon
receipt of an undertaking by such person to repay such amount if, and to the
extent that, such person is ultimately found not to be entitled to
indemnification.  The Company's By-laws also provide that the Company may enter
into agreements with its officers and directors with respect to indemnification
and advancement of expenses, and the Company has entered into such agreements
with its directors and certain of its officers.  The agreements provide for
indemnification and advancement of expenses to the extent provided for in the
Company's By-laws.  The Company has established a grantor trust to fund the
Company's obligations under the agreements.

Item 16.         List of Exhibits.  (See "Exhibit Index")

Item 17.         Undertakings.

         The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each report filed
by the Company pursuant to Section 13(a) or Section 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act
of 1934) that is incorporated by reference in the Registration Statement shall
be deemed to be a new Registration Statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.





                                      II-2
<PAGE>   33
         Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Company pursuant to the foregoing provisions, or otherwise, the
Company has been advised that in the opinion of the SEC such indemnification is
against public policy as expressed in the Act and is, therefore, unenforceable.
In the event that a claim for indemnification against such liabilities (other
than the payment by the Company of expenses incurred or paid by a director,
officer or controlling person of the Company in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered under
this Registration Statement, the Company will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

         The undersigned registrant hereby undertakes:

         (1)  To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement:

                 (i)  To include any prospectus required by Section 10(a)(3) of
the Securities Act of 1933;

                 (ii)  To reflect in the prospectus any facts or events arising
after the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the registration
statement;

                 (iii)  To include any material information with respect to the
plan of distribution not previously disclosed in the registration statement or
any material change to such information in the registration statement;
provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
registration statement is on Form S-3 or Form S-8, and the information required
to be included in a post-effective amendment by those paragraphs is contained
in periodic reports filed by the registrant pursuant to Section 13 or Section
15(d) of the Securities Exchange Act of 1934 that are incorporated by reference
in the registration statement.

         (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, each post-effective amendment shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3)  To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

          3.  Representations and Warranties of the Company.  The Company
represents and warrants to each of the Underwriters, as of the date hereof and
as of the Closing Date (as hereinafter defined), that:

          (a)  The Company has filed with the Securities and Exchange
     Commission (the "Commission") a registration statement on Form S-3 (No.
     33-_____) under the Securities Act of 1933, as amended (the "Act"), for
     the registration of the Bonds under the Act.  The various parts of such
     registration statement, including all exhibits thereto and the documents
     incorporated by reference in the prospectus contained therein at the time
     such part of the registration statement became effective but excluding
     Form T-1, each as amended at the time such part of the registration
     statement became effective, is hereinafter called the "Registration
     Statement" and any reference to any amendment to the Registration
     Statement shall be deemed to refer to and include any document filed
     pursuant to Section 13(a) or 15(d) of the Exchange Act after the effective
     date of the Registration Statement that is incorporated by reference in
     the Registration Statement.  The Registration Statement and any
     post-effective amendment thereto, each in the form heretofore delivered or
     to be delivered to the Representatives and, excluding exhibits to the
     Registration Statement, to the Representatives for each of the other
     Underwriters, if any, have been declared effective by the Commission in
     such form.  No other document with respect to the Registration Statement
     or document incorporated by reference therein has heretofore been filed or
     transmitted for filing with the Commission, no stop order suspending the
     effectiveness of the Registration Statement has been issued and no
     proceeding for that purpose has been initiated or threatened by the
     Commission.  Any preliminary prospectus included in the Registration
     Statement or filed with the Commission pursuant to Rule 424(a) of the
     rules and regulations of the Commission under the Act is hereinafter
     called a "Preliminary Prospectus"; the prospectus relating to the Bonds,
     in the form in which it has most recently been filed, or transmitted for
     filing, with the Commission on or prior to the date of this Agreement, is
     hereinafter called the "Prospectus"; any reference herein to any
     Preliminary Prospectus or the Prospectus shall be deemed to refer to and
     include the documents incorporated by reference therein pursuant to the
     applicable form under the Act, as of the date of such Preliminary
     Prospectus or Prospectus, as the
<PAGE>   3
                                                                               3


     case may be; any reference to any amendment or supplement to any
     Preliminary Prospectus or the Prospectus shall be deemed to refer to and
     include any documents filed after the date of such Preliminary Prospectus
     or Prospectus, as the case may be, under the Securities Exchange Act of
     1934, as amended (the "Exchange Act"), and incorporated by reference in
     such Preliminary Prospectus or Prospectus, as the case may be; and any
     reference to the Prospectus as amended or supplemented shall be deemed to
     refer to the Prospectus as amended or supplemented in relation to the
     Bonds in the form in which it is filed with the Commission pursuant to
     Rule 424(b) under the Act, including any documents incorporated by
     reference therein as of the date of such filing.  The Company will not
     file any amendment to the Registration Statement or any amendment or
     supplement to any Preliminary Prospectus or Prospectus, or file any
     document under the Exchange Act before the termination of the offering of
     the Bonds by the Underwriters if such document would be deemed to be
     incorporated by reference into such Preliminary Prospectus or Prospectus,
     of which the Representatives shall not previously have been advised and
     provided with a copy or to which the Representatives shall reasonably
     object in writing or which shall be disapproved by Messrs. Milbank, Tweed,
     Hadley & McCloy, who are acting as counsel on behalf of the Underwriters.

          (b)  The Registration Statement and the Prospectus and any amendment
     or supplement thereto as of their respective effective or issue dates, and
     as of the closing date, (1) contained or will contain, as applicable, all
     statements of material fact required to be stated therein in accordance
     with the Act and the Rules and Regulations (as defined below); (2)
     conformed or will conform, as applicable, in all material respects to the
     requirements of the Act and the Rules and Regulations and the Trust
     Indenture Act of 1939, as amended (the "Trust Indenture Act"), and the
     rules, regulations and releases of the Commission thereunder; and (3) do
     not and will not include any untrue statement of a material fact or omit
     to state any material fact required to be stated therein or necessary to
     make the statements therein not misleading, except that the foregoing does
     not apply to statements or omissions in such documents based upon written
     information furnished to the Company by any Underwriter specifically for
     use therein or to any statements in or omissions from the statement of
     eligibility and qualification on Form T-1, or amendments thereto, of the
     Trustee under the Indenture.  Any reference to "Rules and Regulations"
     shall mean the rules, regulations and releases adopted by the Commission
     under either the Act or the Exchange Act, as applicable.

          (c)  The financial statements and schedules (including the related
     notes and supporting schedules) included or

     amended or supplemented present fairly the financial condition and
     operations of the Company at the respective dates or for the respective
     periods to which they apply except as otherwise indicated in the
     Registration Statement or Prospectus as amended or supplemented; such
     financial statements have been prepared in each case in accordance with
     generally accepted accounting principles consistently applied throughout
     the periods involved except as otherwise indicated in the Registration
     Statement and Prospectus as amended or supplemented.  Ernst & Young, who
     have examined the audited financial statements and schedules (including
     the related notes and supporting schedules) included or incorporated by
     reference in the Registration Statement or Prospectus as amended or
     supplemented and whose report appears or is incorporated by reference in
     the Prospectus as amended or supplemented, are independent public
     accountants as required by the Act and the Rules and Regulations.

          (d)  Except as reflected in, or contemplated by, the Registration
     Statement and the Prospectus as amended or supplemented, since the
     respective most recent dates as of which information is given in the
     Registration Statement and the Prospectus as amended or supplemented,
     there has not been any material adverse change in the business, properties
     or financial condition or results of operation of the Company, and since
     such dates there has not been any material transaction entered into by the
     Company other than transactions contemplated by the Registration Statement
     and Prospectus as amended or supplemented and transactions in the ordinary
     course of business.  The Company has no material contingent obligation
     which is not disclosed in the Registration Statement and Prospectus as
     amended or supplemented.

          (e)  The consummation of the transactions herein contemplated and the
     fulfillment of the terms hereof on the part of the Company to be fulfilled
     have been duly authorized by all necessary corporate action of the Company
     in accordance with the provisions of its Restated and Amended Certificate
     of Incorporation (the "Charter") and by-laws and applicable law, and the
     Bonds, when issued and delivered as provided herein, and the Pledged
     Bonds, if any, when issued and deposited pursuant to the Indenture, will
     constitute legal, valid and binding obligations of the Company enforceable
     in accordance with their terms except as limited by bankruptcy,
     insolvency, reorganization and other laws of general applicability
     relating to or affecting creditors' rights and to general equity
     principles.  The Bonds and the Pledged Bonds conform to the description
     thereof contained in the Registration Statement and the Prospectus as
     amended or supplemented.

                                                                               5


          (f)  The issuance and sale of the Bonds, the consummation of the
     transactions herein contemplated, the fulfillment of the terms hereof and
     the compliance by the Company with all the terms and provisions of the
     Indenture and the First Mortgage Indenture will not result in a breach of
     any of the terms or provisions of, or constitute a default under, any
     indenture, mortgage, deed of trust or other agreement or instrument to
     which the Company is now a party.

          (g)  The documents which are incorporated by reference in the
     Prospectus as amended or supplemented or from which information is so
     incorporated by reference, when they became effective or were filed with
     the Commission, as the case may be, complied in all material respects with
     the requirements of the Act or the Exchange Act, as applicable, and the
     Rules and Regulations, and any documents so filed and incorporated by
     reference subsequent to the effective date of the Registration Statement
     shall, when they are filed with the Commission, conform in all material
     respects to the requirements of the Act or the Exchange Act, as
     applicable, and the Rules and Regulations.

          (h)  The conditions for use of Form S-3, set forth in the General
     Instructions thereto, have been satisfied.

          4.  Purchase and Sale.  On the basis of the representations and
warranties herein contained, but subject to the terms and conditions herein set
forth, the Company agrees to issue and sell to each of the Underwriters, and
each such Underwriter agrees, severally and not jointly, to purchase from the
Company, at the purchase price set forth in Schedule I hereto, the principal
amount of the Bonds set forth opposite the name of such Underwriter in Schedule
II hereto.

          5.  Reoffering by Underwriters.  Subject to the terms and conditions
of this Agreement, it is understood that the Underwriters propose to make a
bona fide public offering of the Bonds as soon as practicable after the
execution of this Agreement.

          6.  Time and Place of Closing.  Delivery of the Bonds and payment
therefor shall be made at the offices of Milbank, Tweed, Hadley & McCloy, 1
Chase Manhattan Plaza, New York, New York at _____ A.M., New York Time, on
____________, 199__, or such other place, time and date as the Representatives
and the Company may agree upon.  The hour and date of such delivery and payment
are herein called the "Closing Date".  Payment for the Bonds shall be by
certified or official bank check payable to the order of the Company in New
York Clearing House (next day) funds.  The Bonds shall be delivered to the
Representatives for the respective accounts of the Underwriters registered in
such names and in such authorized denominations as the Representatives may
<PAGE>   6
                                                                               6


reasonably request in writing not later than 12:30 P.M., New York Time, on the
third business day prior to the Closing Date, or, to the extent not so
requested, registered in the names of the respective Underwriters in such
authorized denominations as the Company shall determine.  For the purpose of
expediting the checking of the Bonds by the Representatives on behalf of the
Underwriters, the Company agrees to make such Bonds available to the
Representatives for such purposes at the corporate trust office of
[Manufacturers Hanover Trust Company] not later than 2:00 P.M., New York Time,
on the business day preceding the Closing Date, or at such other time and place
as may be agreed upon by the Company and the Representatives.

          If any Underwriter or Underwriters default in its or their
obligations to purchase the Bonds which it or they have agreed to purchase
hereunder and the aggregate principal amount of Bonds which such defaulting
Underwriter or Underwriters agreed but failed to purchase is ten percent or
less of the aggregate principal amount of Bonds set forth in Schedule II
hereto, the other Underwriters shall be obligated severally, in proportion to
their respective commitments to purchase Bonds hereunder, to purchase the Bonds
which such defaulting Underwriter or Underwriters agreed but failed to
purchase.  If any Underwriter or Underwriters so default and the aggregate
principal amount of Bonds with respect to which such default or defaults occur
is more than ten percent of the aggregate principal amount of Bonds set forth
in Schedule II hereto and arrangements satisfactory to you and the Company for
the purchase of such Bonds by other persons are not made within thirty-six
hours after such default, the Company may, at its option, either (a) terminate
this Agreement without liability on the part of any non-defaulting Underwriter
or the Company, except for expenses to be paid or reimbursed by the Company
pursuant to Section 7, or (b) require each non-defaulting Underwriter to
purchase the aggregate principal amount of Bonds which such Underwriter
otherwise agreed to purchase plus an amount equal to one-ninth thereof.  As
used in this Agreement, the term "Underwriter" includes any person substituted
for an Underwriter under this Section.

          The respective commitments of the several Underwriters for purposes
of this paragraph shall be determined without regard to reduction in the
respective Underwriters' obligations to purchase the principal amount of Bonds
set forth opposite their names in Schedule II hereto.  Nothing herein will
relieve a defaulting Underwriter from liability for its default.

          7.  Covenants of the Company.  The Company agrees that:

          (a)  The Company will prepare the Prospectus as amended or
     supplemented in a form approved by the Representatives and will file such
     Prospectus pursuant to Rule 424(b) under the Act not later than the
     Commission's close of business on the second business day following the
     execution and delivery of this Agreement or, if applicable, such earlier
     time as may be required by Rule 424(b).  The Company will at or prior to
     the Closing Date deliver to each of the Representatives and to counsel for
     the Underwriters one signed copy of the Registration Statement as
     originally filed and of all amendments or supplements thereto (including
     conformed copies of any document filed under the Exchange Act and deemed
     to be incorporated by reference into the Prospectus as amended or
     supplemented), heretofore or hereafter made, including any post-effective
     amendment (in each case including all exhibits filed therewith, except
     exhibits incorporated by reference unless specifically requested),
     including a signed copy of each consent and certificate included therein
     or filed as an exhibit thereto.  As soon as the Company is advised
     thereof, it will advise the Representatives orally (i) when any amendment
     to the Registration Statement has been filed or becomes effective or any
     supplement to the Prospectus or any amended Prospectus has been filed with
     the Commission and (ii) of the issuance of any stop order under the Act
     with respect to the Registration Statement or any suspension of the
     qualification of the Bonds in any jurisdiction, or the institution of any
     proceedings therefor of which the Company shall have received notice, and
     will use its best efforts to prevent the issuance of any such stop order
     or suspension and to secure the prompt removal thereof if issued.  The
     Company will deliver to the Underwriters, in accordance with the
     Representatives' instructions, as many copies of the Prospectus as amended
     or supplemented as the Representatives may reasonably request for the
     purposes contemplated by the Act, and will deliver to the Representatives
     as soon as practicable sufficient conformed copies of the Registration
     Statement (including conformed copies of any document filed under the
     Exchange Act and deemed to be incorporated by reference into the
     Prospectus as amended or supplemented) and of all amendments thereto (in
     each case without exhibits) for distribution of one to each Underwriter.

          (b)  The Company will pay all expenses incident to the performance of
     its obligations under this Agreement and will reimburse the Underwriters
     for any expenses up to $9,000 (including fees and disbursements of
     counsel) incurred by them in connection with qualification of the Bonds
     for sale and the preparation of memoranda as to Blue Sky qualifications
     and exemptions and as to eligibility of the Bonds for investment under the
     laws of such jurisdictions as
<PAGE>   8
                                                                               8


     you designate.  The Company shall not, however, be required to pay any
     amount for any expenses of the Representatives or any of the Underwriters
     except as provided in paragraph 4 hereof and except, that in the event
     this Agreement shall be terminated in accordance with the provisions of
     paragraph 8 or 9 hereof, the Company will pay the fees and disbursements
     of counsel for the Underwriters, whose fees and disbursements the
     Underwriters agree to pay in any other event.  The Company shall not in
     any event be liable to any of the several Underwriters for damages on
     account of loss of anticipated profits.

          (c)  If at any time when a prospectus relating to the Bonds is
     required to be delivered under the Act, any event relating to or affecting
     the Company, or of which the Company shall be advised in writing by the
     Representatives, shall occur, which in the opinion of the Company should
     be set forth in a supplement to or an amendment of the Prospectus in order
     to make the Prospectus as amended or supplemented not misleading in the
     light of the circumstances when it is delivered, or which, in your
     opinion, may be necessary in connection with the distribution of the
     Bonds, the Company will forthwith at its expense prepare and furnish to
     the Representatives a reasonable number of copies of a supplement or
     supplements or an amendment or amendments to the Prospectus as amended or
     supplemented which will supplement or amend the Prospectus as amended or
     supplemented or file such documents so that the Prospectus as amended or
     supplemented will not contain any untrue statement of a material fact or
     omit to state any material fact necessary in order to make the statements
     therein, in the light of the circumstances when the Prospectus as amended
     or supplemented is delivered, not misleading.  The Company will continue
     to prepare and file with the Commission in a timely manner all documents
     required to be filed pursuant to the requirements of the Exchange Act and
     the Rules and Regulations.

          (d)  The Company will make generally available to its security
     holders (and shall deliver to the Representatives), as soon as practicable
     but in any event not later than 45 days after the end of its fiscal
     quarter in which the first anniversary date of the effective date of the
     Registration Statement (as such term is defined in Rule 158 under the Act)
     (the "Effective Date") occurs, an earnings statement (which need not be
     audited, unless required so to be under Section 11(a) of the Act) of the
     Company in reasonable detail covering a period of at least twelve
     consecutive months beginning after the Effective Date.

          (e)  The Company will use its best efforts promptly to do and perform
     all things to be done and performed by it
<PAGE>   9
                                                                               9


     hereunder prior to the Closing Date and to satisfy all conditions
     precedent to the delivery by it of the Bonds.

          (f)  The Company will use its best efforts to qualify the Bonds for
     offer and sale under the Blue Sky laws of such states as the
     Representatives may designate and will file such statements or reports as
     are or may be reasonably required by the laws of such states; provided,
     however, that the Company in complying with this paragraph need not
     qualify to do business in any state nor execute a general consent to
     service of process.

          (g)  The Company will effect such filing and recordation with respect
     to the ____________ Supplemental Indenture to the Indenture and the
     __________ Supplemental Indenture to the First Mortgage Indenture, at or
     as soon as practicable after the Closing Date in all places required by
     law as shall be necessary in order to secure fully the Bonds and the
     Pledged Bonds under the lien of the Indenture and the First Mortgage
     Indenture and to furnish the Representatives with an opinion of counsel
     that such filing and recordation with respect to such indentures have been
     effected without the intervention of any prior liens, charges or
     encumbrances except (a) Excepted Encumbrances, as defined in the
     Indenture, and Permitted Encumbrances, as defined in the First Mortgage
     Indenture, (b) minor restrictions, exceptions and reservations in
     conveyances and minor defects of title, which are of the nature ordinarily
     found in properties of similar character and which do not interfere
     adversely with the operation of the business of the Company or in any
     substantial way impair the security afforded by the Indenture and the
     First Mortgage Indenture, and (c) any lien against property of the Company
     as to which cash sufficient to pay indebtedness secured by such lien is
     held irrevocably in trust for such purpose by the trustee under the First
     Mortgage Indenture.

          (h)  The Company will apply the proceeds of the sale of the Bonds,
     exclusive of accrued interest, if any, for the purposes set forth in the
     Prospectus as amended or supplemented.

          8.  Conditions of Underwriters' Obligations.  The several obligations
of the Underwriters to purchase and pay for the Bonds shall be subject to the
accuracy of, and compliance with, the representations and warranties of the
Company contained herein, to the performance by the Company of its obligations
to be performed hereunder prior to the Closing Date, and to the following
further conditions:

          (a)  The Prospectus as amended or supplemented in relation to the
     Bonds shall have been filed with the Commission pursuant to Rule 424(b)

     time period prescribed for such filing by the Rules and Regulations; and
     no stop order suspending the effectiveness of the Registration Statement
     shall be in effect on the Closing Date and no proceedings for that purpose

     Date.  The Representatives shall have received, prior to payment for the
     Bonds, a certificate dated the Closing Date and signed by the President,
     any Vice President or the Treasurer of the Company to the effect that no
     such stop order is in effect and that no proceedings for such purpose are
     pending before, or to the knowledge of the Company threatened by, the
     Commission.

          (b)  On the Closing Date there shall be in full force and effect an
     order of the Public Service Commission of the State of New York
     authorizing the issuance and sale of debt securities, including the Bonds,
     and the issuance and deposit of the Pledged Bonds which shall not contain
     any provision mutually unacceptable to the Representatives and the Company
     by reason of being materially adverse, it being understood that no order
     in effect at the date of this Agreement contains any such unacceptable
     provision.

          (c)  At the Closing Date, the Representatives shall receive a
     favorable opinion from either Robert J. Grey, Esq., General Counsel of the
     Company, or Herbert M. Leiman, Esq., Assistant General Counsel of the
     Company, which opinion shall be satisfactory in form and substance to
     Messrs. Milbank, Tweed, Hadley & McCloy, counsel for the Underwriters, to
     the effect that

               (i)  The Company is a corporation duly organized and validly
          existing, in good standing under the laws of the State of New York,
          and has power and authority (corporate and other) to own its

          delivered by the Company;

             (iii)  An order has been adopted by the New York Public Service
          Commission authorizing the issuance and sale of the Bonds, and the
          issuance and deposit of the Pledged Bonds and the transactions
          related thereto as contemplated by the Agreement and said order is
          still in full force and effect; and no further approval,
          authorization, consent or other order of any public board or body is
          legally required for the authorization of the issuance and sale by
          the Company of the Bonds and the issuance and deposit of the Pledged
          Bonds under the terms of this Agreement except compliance with the
          provisions of securities or Blue Sky laws of certain

                                                                              11


          states in connection with the sale of the Bonds to the public in such
          states;

              (iv)  The execution, delivery and performance of this Agreement,
          the Indenture, the First Mortgage Indenture, the Bonds and the
          Pledged Bonds by the Company and the consummation by the Company of
          the transactions contemplated hereby and thereby will not conflict
          with or result in a breach or violation by the Company of any of the

          loan agreement, lease or other agreement or instrument known to such
          counsel to which the Company is a party or to which it or any of its
          properties is subject, (B) the Charter or by-laws of the Company or
          (C) any statute, rule or regulation or, to the best of such counsel's
          knowledge, any judgment, decree or order of any court or governmental
          agency or body applicable to the Company or any of its properties;

               (v)  The Indenture and the First Mortgage Indenture conform to
          the statements with respect thereto contained in the Registration
          Statement and Prospectus as amended or supplemented, have been duly
          authorized by the Company and duly executed and delivered, and are
          legal, valid and binding agreements of the Company enforceable in
          accordance with their terms, subject, however, to the qualification
          that certain of the remedial provisions thereof may be limited by the
          laws of New York (but such laws do not make the remedies afforded
          inadequate for the realization of the benefits of the security
          provided thereby) and, with respect to atomic energy facilities, by
          the Atomic Energy Act of 1954 and regulations thereunder, and as to
          enforcement, to bankruptcy, insolvency, reorganization and other laws
          of general applicability relating to or affecting creditors' rights
          and to general equity principles.  The First Mortgage Indenture, as
          supplemented by the first ___________ supplemental indentures, and
          the Indenture, as supplemented by the first ___________ supplemental
          indentures, have been duly filed for record and recorded under the
          laws of New York as mortgages of real and personal property in each
          proper office in all counties or other recording districts in New
          York in which the properties subject to the lien of the First
          Mortgage Indenture and the Indenture are located, and all necessary
          filings to date have been made under the New York Uniform Commercial
          Code, in order to perfect

                                                                              12


          and preserve the lien of the First Mortgage Indenture and the
          Indenture upon the properties intended to be covered thereby, and all
          mortgage recording or other taxes (other than statutory recording
          fees and Federal taxes) required to be paid in connection therewith
          have been paid.  Subject to the due recordation of the ____________
          Supplemental Indenture to the First Mortgage Indenture and the
          ____________ Supplemental Indenture to the Indenture and payment of
          the New York mortgage recording tax, the First Mortgage Indenture and
          the Indenture constitute, respectively, a valid and enforceable first
          mortgage lien and a valid and enforceable mortgage lien junior to the
          lien of the First Mortgage Indenture upon the properties intended to
          be subject thereto, subject to no liens, charges or encumbrances
          except (a) Permitted Encumbrances, as defined in the First Mortgage
          Indenture, and Excepted Encumbrances, as defined in the Indenture,
          (b) minor restrictions, exceptions and reservations in conveyances
          and minor defects of title, which are of the nature ordinarily found
          in properties of similar character and which do not interfere
          adversely with the operation of the business of the Company or in any
          substantial way impair the security afforded by the First Mortgage
          Indenture and the Indenture and (c) any lien against property of the
          Company as to which cash sufficient to pay indebtedness secured by
          such lien is held irrevocably in trust for such purpose by the
          trustee under the First Mortgage Indenture.  The Indenture has been
          duly qualified under the Trust Indenture Act;

              (vi)  The Bonds conform to the terms of this Agreement and to the
          statements with respect thereto contained in the Registration
          Statement and Prospectus as amended or supplemented and have been
          duly authorized; the Bonds have been duly executed, authenticated and
          delivered and are legal, valid and binding obligations of the Company
          enforceable in accordance with their terms and are entitled to the
          benefits and security afforded by the Indenture in accordance with
          the terms of such Indenture and such Bonds;

             (vii)  The Pledged Bonds conform to the terms of this Agreement
          and to the statements with respect thereto contained in the
          Registration Statement and Prospectus as amended or supplemented and
          have been duly authorized, and, when duly executed, authenticated,
          issued and deposited with the Trustee pursuant to the Indenture as
          security for Bonds issued and to be issued thereunder, will be,
          except as limited by certain terms of the Indenture, entitled to the

                                                                              13


          security afforded by the First Mortgage Indenture in accordance with
          the terms of the First Mortgage Indenture and the terms of the
          Pledged Bonds;

            (viii)  The Company has good and marketable title in fee simple
          absolute to all the parcels of real property described in the
          Indenture and the First Mortgage Indenture as being subject thereto,
          except such parcels as may have been released or are in process of
          being released pursuant to the terms thereof, and good title to all
          other property owned by the Company (other than rights of way for
          transmission and distribution lines and mains located either within
          the limits of public highways, or on private property pursuant to
          easements from apparent owners containing in some instances removal
          and relocation provisions and time limits, or on private property
          without easements where such lines and mains, with minor exceptions,
          are being maintained without objection from the owners of such
          property) in each case free and clear of all liens, charges and
          encumbrances except (a) the lien of the Indenture and Excepted
          Encumbrances as defined therein, and the lien of the First Mortgage
          Indenture and Permitted Encumbrances as defined therein, (b) minor
          restrictions, exceptions and reservations in conveyances and minor
          defects of title, which are of the nature ordinarily found in
          properties of similar character and which do not interfere adversely
          with the operation of the business of the Company or in any
          substantial way impair the security afforded by the Indenture or the
          First Mortgage Indenture and (c) any lien against property of the
          Company as to which cash sufficient to pay indebtedness secured by
          such lien is held irrevocably in trust for such purpose by the
          Trustee under the Indenture or by the trustee under the First
          Mortgage Indenture.  The properties described in the Indenture and
          the First Mortgage Indenture are adequately described to constitute
          the Indenture and the First Mortgage Indenture liens thereon;

               (ix)  The Company, to the best of such counsel's knowledge,
          possesses all franchises, licenses, permits, consents and orders of
          governmental and regulatory authorities and political subdivisions
          required for the maintenance and operation of its properties and
          business substantially as now conducted and as described in the
          Registration Statement and the Prospectus as amended or supplemented;
          or, if the Company does not possess all of such franchises, licenses,
          permits, consents and orders, the absence of such thereof as the
          Company does not possess will not, to the best of such counsel's
          knowledge, affect the
<PAGE>   14
                                                                              14


          maintenance and operation of such properties and business as a whole
          substantially as now conducted; and

               (x)  The Registration Statement has become effective under the
          Act and, to the best knowledge of such counsel, no stop order
          suspending the effectiveness of the Registration Statement has been
          issued and no proceedings for that purpose have been instituted or
          are pending or contemplated under the Act, the Registration Statement
          and the Prospectus, and each amendment or supplement thereto
          (including any document incorporated by reference into the Prospectus
          as amended or supplemented), as of their respective effective or
          issue dates, complied as to form in all material respects with the
          requirements of the Act, the Exchange Act and the Trust Indenture Act
          and the applicable rules and regulations of the Commission
          thereunder; the conditions for use of Form S-3, set forth in the
          General Instructions thereto, have been satisfied; such counsel has
          no reason to believe that either the Registration Statement or the
          Prospectus, or any such amendment or supplement (including any
          document filed under the Exchange Act and deemed to be incorporated
          by reference into the Prospectus as amended or supplemented),
          considered as a whole on the effective date of the Registration
          Statement and on the date hereof, contained or contain any untrue
          statement of material fact or omitted or omit to state any material
          fact required to be stated therein or necessary to make the
          statements therein not misleading; the descriptions in the
          Registration Statement and the Prospectus as amended or supplemented
          of statutes, legal and governmental proceedings and contracts and
          other documents are accurate and fairly present the information
          required to be shown; and such counsel does not know of any legal or
          governmental proceedings required to be described in the Prospectus
          as amended or supplemented (or required to be filed under the
          Exchange Act if upon such filing they would be incorporated, in whole
          or in part, by reference in the Prospectus as amended or
          supplemented) which are not described as required, nor of any
          contracts or documents of a character required to be described in the
          Registration Statement or Prospectus as amended or supplemented or to
          be filed as exhibits to the Registration Statement which are not
          described and filed as required; it being understood that such
          counsel need express no opinion as to the financial statements or
          other financial data contained or incorporated by reference in the
          Registration Statement or the Prospectus as amended or supplemented.

          (d)  At the Closing Date, the Representatives shall receive from
     Messrs. Milbank, Tweed, Hadley & McCloy, counsel for the Underwriters,
     such opinion or opinions with respect to the valid existence of the
     Company, the validity of the Bonds and the Pledged Bonds (if any are to be
     issued concurrently with the Bonds), the Registration Statement, the
     Prospectus as amended or supplemented, and other related matters as you
     may require, and the Company shall have furnished to such counsel such
     documents as they request for the purpose of enabling them to pass upon
     such matters.

          (e)  On the date of this Agreement and on the Closing Date the
     Representatives shall have received from Ernst & Young a letter (with
     copies thereof for each of the Underwriters), which letter shall be
     reasonably satisfactory in form and substance to the Representatives and
     Messrs. Milbank, Tweed, Hadley & McCloy, counsel for the Underwriters,
     confirming that they are independent auditors with respect to the Company
     within the meaning of the Act and the applicable published rules and
     regulations thereunder, and stating in effect that:

               (i)  in their opinion, the audited financial statements and

          and the Prospectus as amended or supplemented audited by them comply
          as to form in all material respects with the applicable accounting
          requirements of the Act or the Exchange Act, as applicable, and the
          applicable published rules and regulations of the Commission
          thereunder with respect to a registration statement on Form S-3;

               (ii)  they have read the minutes of the meetings of the
          stockholders and the Board of Directors of the Company, as set forth
          in the minute books or, if not set forth therein, in the form
          prepared by the Secretary of the Company, through a specified date
          not more than five business days prior to the date of the closing,
          read the unaudited financial statements, if any, incorporated by
          reference into the Registration Statement and Prospectus as amended
          or supplemented and also the latest available unaudited interim
          financial statements of the Company and inquired of certain officials
          of the Company responsible for financial and accounting matters, and
          that such officials have stated that:

                     (A)  any unaudited Balance Sheet, Statement of Income and
               Statement of Cash Flows included or incorporated by reference in
               the Registration Statement and Prospectus as amended or

               requirements of the Act and the Exchange Act and the published
               rules and regulations of the Commission thereunder, and are in
               conformity with generally accepted accounting principles applied
               on a basis substantially consistent with that of the most recent
               audited financial statements included or incorporated by
               reference therein,

                     (B)  at the date of the latest available balance sheet
               read by such accountants, there was no change in the capital
               stock (including Common Stock, Preferred Stock and Premium on
               Capital Stock but excluding Capital Stock Expense) or long-term
               debt of the Company or any decrease in net current assets or
               Common Shareowners' Equity as compared with amounts shown on the
               latest balance sheet included or incorporated by reference in
               the Registration Statement and Prospectus as amended or
               supplemented, except in all instances (i) for changes or
               decreases that the Registration Statement and Prospectus as

               (iii) for conversions of convertible preferred stock, (iv) for
               shares of common stock issued pursuant to the Company's Employee

               letter, identifying the same and specifying the amount thereof,
               or

                     (C)  for the twelve months ending on the date of the
               latest available unaudited interim financial statements of the
               Company, there were no decreases, as compared with the twelve

          referred to in said clause and inquired of certain officials of the
          Company responsible for financial and accounting matters, and that
          such officials have stated that, with respect to the period from the
          date of the latest available financial statements of the Company to a
          specified date not more than five business days prior to the date of

          thereof; and

               (iv)  they have compared certain dollar amounts (and percentages
          and other financial data derived from such dollar amounts) disclosed
          in, or incorporated by reference into, the Registration Statement and

          Registration Statement, with such dollar amounts, percentages and
          other financial information contained in the general accounting
          records of the Company or derived directly from such records by
          analysis or computation, and have found such dollar amounts,
          percentages and other financial information to be in agreement
          therewith, except as otherwise specified in such letter.

          (f)  Since the respective most recent dates of which information is
     given in the Registration Statement and Prospectus as amended or

     President or the Treasurer of the Company.

          (g)  All legal proceedings to be taken in connection with the
     issuance and sale of the Bonds shall have been satisfactory in form and
     substance to Messrs. Milbank, Tweed, Hadley & McCloy.

                                                                              19


any untrue statement or alleged untrue statement of a material fact contained
in any Preliminary Prospectus, any preliminary prospectus supplement, the
Registration Statement, the Prospectus as amended or supplemented or any
amendment or supplement thereto (if any amendments or supplements thereto shall
have been furnished) or the omission or alleged omission to state therein a

of the Prospectus, as the same may then be supplemented or amended, to such
person with or prior to the written confirmation of the sale involved so long
as the Company shall have fully complied with the last sentence of Section 7(a)
hereof.  The indemnity agreement of the Company contained in this paragraph and
the representations and warranties of the Company contained in Section 3 hereof
shall remain operative and in full force and effect, regardless of any
investigation made by or on behalf of any Underwriter or any such controlling
person, and shall survive the delivery of the Bonds.  The Underwriters agree
promptly to notify the Company of the commencement of any litigation or
proceedings against them or any of them, or any such controlling person, in
connection with the sale of the Bonds or with any Preliminary Prospectus, any
preliminary prospectus supplement, the Registration Statement, the Prospectus
as amended or supplemented or any amendment or supplement thereto.

          (b)  Each Underwriter agrees to indemnify and hold harmless the
Company, its officers and directors, each other Underwriter, and each person
who controls any thereof within the meaning of Section 15 of the Act, against
any and all losses, claims, damages or liabilities, joint or several, to which
they or any of them become subject under the Act or any other statute or common
law and to reimburse each of them for any legal or other expenses (including,
to the extent hereinafter provided, reasonable counsel fees) incurred by them
in connection with investigating any such losses, claims, damages or
liabilities or in connection with defending any actions, insofar as such
losses, claims, damages, liabilities, expenses or actions arise out of or
<PAGE>   20
                                                                              20


are based upon (i) any untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, any preliminary
prospectus supplement, the Registration Statement, the Prospectus as amended or
supplemented or any amendment or supplement thereto (if any amendments or
supplements thereto shall have been furnished) or (ii) the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, if such statement or
omission was made in reliance upon information furnished herein or in writing
to the Company by or on behalf of such Underwriter, through the
Representatives, expressly for use in any Preliminary Prospectus, any
preliminary prospectus supplement, the Registration Statement, the Prospectus
as amended or supplemented or any amendment or supplement thereto.  The
indemnity agreement of the respective Underwriters contained in this paragraph
shall remain operative and in full force and effect, regardless of any
investigation made by or on behalf of the Company, or any such other
Underwriter or any such controlling person, and shall survive the delivery of
the Bonds.  The Company agrees promptly to notify the Representatives of the
commencement of any litigation or proceedings against the Company or any of its
officers or directors or against any such controlling person in connection with
the sale of the Bonds or with any Preliminary Prospectus, any preliminary
prospectus supplement, the Registration Statement, the Prospectus as amended or
supplemented or any amendment or supplement thereto.

          (c)  The Company and each of the Underwriters agree that, upon
receipt of notice of the commencement of any action against the Company or any
person controlling the Company, or against such Underwriter or any person
controlling such Underwriter, in respect of which indemnity may be sought on
account of any indemnity agreement contained herein, it will promptly give
written notice of the commencement thereof to the party or parties against whom
indemnity shall be sought hereunder, but the omission so to notify such
indemnifying party or parties of any such action shall not relieve such
indemnifying party or parties from any liability which it or they may have to
the indemnified party (i) to the extent the indemnifying party was not
materially prejudiced by such omission or (ii) otherwise than on account of
such indemnity agreement.  In case such notice of any such action shall be so
given such indemnifying party shall be entitled to participate at its own
expense in the defense or, if it so elects, to assume (in conjunction with any
other indemnifying parties) the defense of such action, in which event such
defense shall be conducted by counsel chosen by such indemnifying party (or
parties) and satisfactory to the indemnified party or parties who shall be
defendant or defendants in such action; provided, however, if the defendants in
any such action include both the indemnified party and the indemnifying party
and the indemnified party shall have reasonably concluded that there may be
legal defenses available to it and/or other
<PAGE>   21
                                                                              21


indemnified parties which are different from or additional to those available
to the indemnifying party, the indemnified party or parties shall have the
right to select separate counsel to assume such legal defenses and to otherwise
participate in the defense of such action on behalf of such indemnified party
or parties.  Upon receipt of notice from the indemnifying party to such
indemnified party of its election so to assume the defense of such action and
approval by the indemnified party of counsel, the indemnifying party will not
be liable to such indemnified party under this Section 10 for any legal or
other expenses subsequently incurred by such indemnified party in connection
with the defense thereof other than reasonable costs of investigation unless
(i) the indemnified party shall have employed such counsel in connection with
the assumption of legal defenses in accordance with the proviso to the next
preceding sentence (it being understood, however, that the indemnifying party
shall not be liable for the expenses of more than one separate counsel,
approved by the Representatives in the case of paragraph (a) of this Section
10, representing the indemnified parties under paragraph (a) or (b) of this
Section 10, as the case may be, who are parties to such action), (ii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of commencement of the action or (iii) the indemnifying party has
authorized the employment of counsel for the indemnified party at the expense
of the indemnifying party.

          (d)  If the indemnification provided for in this Section 10 shall for
any reason be unavailable to an indemnified party under paragraphs (a) or (b)
of this Section 10 in respect of any loss, claim, damage or liability, or any
action in respect thereof, referred to therein, then each indemnifying party
shall, in lieu of indemnifying such indemnified party, contribute to the amount
paid or payable by such indemnified party as a result of such loss, claim,
damage or liability, or action in respect thereof, (i) in such proportion as
shall be appropriate to reflect the relative benefits received by the Company
on the one hand and the Underwriters on the other from the offering of the
Bonds or (ii) if the allocation provided by clause (i) above is not permitted
by applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault
of the Company on the one hand and the Underwriters on the other with respect
to the statements or omissions which resulted in such loss, claim, damage or
liability, or action in respect thereof, as well as any other relevant
equitable considerations.  The relative benefits received by the Company on the
one hand and the Underwriters on the other with respect to such offering shall
be deemed to be in the same proportion as the total net proceeds from the
offering of the Bonds (before deducting expenses) received by the Company bear
to the total underwriting discounts and commissions received by the
Underwriters with respect to such offering, in each case
<PAGE>   22
                                                                              22


as set forth in the table on the cover page of the Prospectus.  The relative
fault shall be determined by reference to whether the untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a
material fact relates to information supplied by the Company or the
Underwriters, the intent of the parties and their relative knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company and the Underwriters agree that it would not be just and equitable
if contributions pursuant to this Section 10 were to be determined by pro rata
allocation or by any other method of allocation which does not take into
account the equitable considerations referred to herein.  The amount paid or
payable by an indemnified party as a result of the loss, claim, damage or
liability, or action in respect thereof, referred to above in this Section 10
shall be deemed to include, for purposes of this Section 10, any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim.  Notwithstanding the
provisions of this Section 10, no Underwriter shall be required to contribute
any amount in excess of the amount by which the total price at which the Bonds
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages which such Underwriter has otherwise paid or
becomes liable to pay by reason of any untrue or alleged untrue statement or
omission or alleged omission.  No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.  The Underwriters' obligations to contribute as provided in
this paragraph (d) are several in proportion to their respective underwriting
obligations and not joint.

          (e)  The agreements contained in this Section 10, the representations
and warranties of the Company in Section 3 hereof and the agreements of the
Company in Section 7 hereof shall survive the delivery of the Bonds.  The
agreements contained in this Section 10, the representations and warranties of
the Company in Section 3 hereof and the agreements of the Company in Section
7(b) hereof shall remain in full force and effect, regardless of any
termination or cancellation of this Agreement or any investigation made by or
on behalf of any indemnified party.

          11.  Termination.  This Agreement may be terminated at any time prior
to the Closing Date by the Representatives with the consent of a majority in
interest of the Underwriters including yourselves upon notice thereof to the
Company, if prior to such time (a) the Company has failed, refused or been
unable to perform any agreement on its part to be performed hereunder, (b) any
other condition of the Underwriters' obligations hereunder is not fulfilled,
(c) there shall have occurred any general suspension of trading in securities
on the New York Stock Exchange or the American Stock Exchange or there shall
have been
<PAGE>   23
                                                                              23


established by the New York Stock Exchange or the American Stock Exchange or by
the Commission or by any federal or state agency or by the decision of any
court any limitation on prices for such trading or any restrictions on the
distribution of securities, (d) a banking moratorium shall have been declared
either by federal or New York State authorities, (e) an outbreak or escalation
of hostilities involving the United States shall have occurred or there shall
have been a declaration by the United States of a national emergency or war or
(f) there shall have occurred such a material adverse change in general
economic, political or financial conditions, or the effect of international
conditions on the financial markets in the United States is such, as to make it
impracticable or inadvisable, in the judgment of a majority in interest of the
Underwriters, to proceed with the delivery of the Bonds.  Any termination
hereof pursuant to this Section 11 shall be without liability of any party to
any other party except as otherwise provided in Section 7 hereof.

          12.  Information Furnished by Underwriters.  The statements set forth
in the last paragraph on the cover page, the paragraph containing stabilization
information on the inside front cover page and the statements under the caption
"Underwriting" in any Prospectus as amended or supplemented constitute the only
written information furnished by or on behalf of any Underwriter referred to in
paragraph (b) of Section 3 hereof and in paragraphs (a) and (b) of Section 10
hereof.

          13.  Miscellaneous.  The validity and interpretation of this
Agreement shall be governed by the laws of the State of New York.  This
Agreement shall inure to the benefit of the Company, the Underwriters and, with
respect to the provisions of Section  10 hereof, each controlling person
referred to in said Section 10, and their respective successors, assigns,
executors and administrators.  Nothing in this Agreement is intended or shall
be construed to give to any other person, firm or corporation any legal or
equitable right, remedy or claim under or in respect of this Agreement or any
provisions herein contained.  The term "successors" as used in this Agreement
shall not include any purchaser, as such purchaser, of any of the Bonds from
any of the Underwriters.

          14.  Notices.  All communications hereunder shall be in writing or by
telegram and, if to the Underwriters, shall be mailed or delivered to the
Representatives c/o Lehman Brothers Inc., 3 World Financial Center, New York,
New York 10285-1100, attention:  Syndicate Department; if to the Company, shall
be mailed or delivered to it at 175 East Old Country Road, Hicksville, New York

[Names of other Representatives]
  As Representatives of the several
  Underwriters
c/o Lehman Brothers Inc.
    3 World Financial Center
    New York, New York  10285-1100

Dear Sirs:

          The undersigned, Long Island Lighting Company (the "Company"), hereby 
confirms its agreement with each of the several underwriters, hereinafter 
named, as follows:

          1.  Underwriters and Representatives.  The term "Underwriters" as
used herein shall be deemed to mean the several firms or corporations named in
Schedule II hereto and any underwriter substituted as provided in Section 6.
The term "Representatives" as used herein shall be deemed to mean Lehman
Brothers Inc., [Names of other Representatives], who represent that they have
been authorized by the Underwriters to execute this Agreement on their behalf
and to act for them in the manner herein provided.  All obligations of the
Underwriters hereunder are several and not joint.  Any action under or in
respect of this Agreement taken by the Representatives will be binding upon all
the Underwriters.

          2.  Description of Debentures.  The Company proposes to issue and
sell to the Underwriters the principal amount of its Debentures identified in
Schedule I hereto (the "Debentures") in one or more series under an Indenture,

<PAGE>   2
                                                                               2


Connecticut Bank and Trust Company, National Association)], as Trustee (the
"Trustee").

          3.  Representations and Warranties of the Company.  The Company
represents and warrants to each of the Underwriters, as of the date hereof and
as of the Closing Date (as hereinafter defined), that:

          (a)  The Company has filed with the Securities and Exchange
     Commission (the "Commission") a registration statement on Form S-3 (No.
     33-_____) under the Securities Act of 1933, as amended (the "Act"), for
     the registration of the Debentures under the Act.  The various parts of
     such registration statement, including all exhibits thereto and the
     documents incorporated by reference in the prospectus contained therein at
     the time such part of such registration statement became effective but
     excluding Form T-1, each as amended at the time such part of the
     registration statement became effective, is hereinafter called the
     "Registration Statement" and any reference to any amendment to the
     Registration Statement shall be deemed to refer to and include any
     document filed pursuant to Section 13(a) or 15(d) of the Exchange Act
     after the effective date of the Registration Statement that is
     incorporated by reference in the Registration Statement.  The Registration
     Statement and any post-effective amendment thereto, each in the form
     heretofore delivered or to be delivered to the Representatives and,
     excluding exhibits to the Registration Statement, to the Representatives
     for each of the other Underwriters, if any, have been declared effective
     by the Commission in such form.  No other document with respect to the
     Registration Statement or document incorporated by reference therein has
     heretofore been filed or transmitted for filing with the Commission, no
     stop order suspending the effectiveness of the Registration Statement has
     been issued and no proceeding for that purpose has been initiated or
     threatened by the Commission.  Any preliminary prospectus included in the
     Registration Statement or filed with the Commission pursuant to Rule
     424(a) of the rules and regulations of the Commission under the Act is
     hereinafter called a "Preliminary Prospectus"; the prospectus relating to
     the Debentures, in the form in which it has most recently been filed with
     the Commission on or prior to the date of this Agreement, is hereinafter
     called the "Prospectus"; any reference herein to any Preliminary
     Prospectus or the Prospectus shall be deemed to refer to and include the
     documents incorporated by reference therein pursuant to the applicable
     form under the Act, as of the date of such Preliminary Prospectus or
     Prospectus, as the case may be; any reference to any amendment or
     supplement to any Preliminary Prospectus or the Prospectus shall be deemed
     to refer to and include any documents filed after the date of
<PAGE>   3
                                                                               3


     such Preliminary Prospectus or Prospectus, as the case may be, under the
     Securities Exchange Act of 1934, as amended (the "Exchange Act"), and
     incorporated by reference in such Preliminary Prospectus or Prospectus, as
     the case may be; and any reference to the Prospectus as amended or
     supplemented shall be deemed to refer to the Prospectus as amended or
     supplemented in relation to the Debentures in the form in which it is
     filed with the Commission pursuant to Rule 424(b) under the Act, including
     any documents incorporated by reference therein as of the date of such
     filing.  The Company will not file any amendment to the Registration
     Statement or any amendment or supplement to any Preliminary Prospectus or
     Prospectus, or file any document under the Exchange Act before the
     termination of the offering of the Debentures by the Underwriters if such
     document would be deemed to be incorporated by reference into such
     Preliminary Prospectus or Prospectus, of which the Representatives shall
     not previously have been advised and provided with a copy or to which the
     Representatives shall reasonably object in writing or which shall be
     disapproved by Messrs. Milbank, Tweed, Hadley & McCloy, who are acting as
     counsel on behalf of the Underwriters.

          (b)  The Registration Statement and the Prospectus and any amendment
     or supplement thereto as of their respective effective or issue dates, and
     as of the closing date, (1) contained or will contain, as applicable, all
     statements of material fact required to be stated therein in accordance
     with the Act and the Rules and Regulations (as defined below); (2)
     conformed or will conform, as applicable, in all material respects to the
     requirements of the Act and the Rules and Regulations and the Trust
     Indenture Act of 1939, as amended (the "Trust Indenture Act"), and the
     rules, regulations and releases of the Commission thereunder; and (3) do
     not and will not include any untrue statement of a material fact or omit
     to state any material fact required to be stated therein or necessary to
     make the statements therein not misleading, except that the foregoing does
     not apply to statements or omissions in such documents based upon written
     information furnished to the Company by any Underwriter specifically for
     use therein or to any statements in or omissions from the statement of
     eligibility and qualification on Form T-1, or amendments thereto, of the
     Trustee under the Indenture.  Any reference to "Rules and Regulations"
     shall mean the rules, regulations and releases adopted by the Commission
     under either the Act or the Exchange Act, as applicable.

          (c)  The financial statements and schedules (including the related
     notes and supporting schedules) included or incorporated by reference in
     the Registration Statement or Prospectus as amended or supplemented
     present fairly the
<PAGE>   4
                                                                               4


     financial condition and operations of the Company at the respective dates
     or for the respective periods to which they apply except as otherwise
     indicated in the Registration Statement or Prospectus as amended or
     supplemented; such financial statements have been prepared in each case in
     accordance with generally accepted accounting principles consistently
     applied throughout the periods involved except as otherwise indicated in
     the Registration Statement and Prospectus as amended or supplemented.
     Ernst & Young, who have examined the audited financial statements and
     schedules (including the related notes and supporting schedules) included
     or incorporated by reference in the Registration Statement or Prospectus
     as amended or supplemented and whose report appears or is incorporated by
     reference in the Prospectus as amended or supplemented, are independent
     public accountants as required by the Act and the Rules and Regulations.

          (d)  Except as reflected in, or contemplated by, the Registration
     Statement and the Prospectus as amended or supplemented, since the
     respective most recent dates as of which information is given in the
     Registration Statement and the Prospectus as amended or supplemented,
     there has not been any material adverse change in the business, properties
     or financial condition or results of operation of the Company, and since
     such dates there has not been any material transaction entered into by the
     Company other than transactions contemplated by the Registration Statement
     and Prospectus as amended or supplemented and transactions in the ordinary
     course of business.  The Company has no material contingent obligation
     which is not disclosed in the Registration Statement and Prospectus as
     amended or supplemented.

          (e)  The consummation of the transactions herein contemplated and
     the fulfillment of the terms hereof on the part of the Company to be
     fulfilled have been duly authorized by all necessary corporate action of
     the Company in accordance with the provisions of its Restated and Amended
     Certificate of Incorporation (the "Charter") and by-laws and applicable
     law, and the Debentures, when issued and delivered as provided herein,
     will constitute legal, valid and binding obligations of the Company
     enforceable in accordance with their terms except as limited by
     bankruptcy, insolvency, reorganization and other laws of general
     applicability relating to or affecting creditors' rights and to general
     equity principles.  The Debentures conform to the description thereof
     contained in the Registration Statement and the Prospectus as amended or
     supplemented.

          (f)  The issuance and sale of the Debentures, the consummation of
     the transactions herein contemplated, the

                                                                               5


     fulfillment of the terms hereof and the compliance by the Company with all
     the terms and provisions of the Indenture will not result in a breach of
     any of the terms or provisions of, or constitute a default under, any
     indenture, mortgage, deed of trust or other agreement or instrument to
     which the Company is now a party.

          (g)  The documents which are incorporated by reference in the
     Prospectus as amended or supplemented or from which information is so
     incorporated by reference, when they became effective or were filed with
     the Commission, as the case may be, complied in all material respects with
     the requirements of the Act or the Exchange Act, as applicable, and the
     Rules and Regulations, and any documents so filed and incorporated by
     reference subsequent to the effective date of the Registration Statement
     shall, when they are filed with the Commission, conform in all material
     respects to the requirements of the Act or the Exchange Act, as
     applicable, and the Rules and Regulations.

          (h)  The conditions for use of Form S-3, set forth in the General
     Instructions thereto, have been satisfied.

          4.  Purchase and Sale.  On the basis of the representations and
warranties herein contained, but subject to the terms and conditions herein set
forth, the Company agrees to issue and sell to each of the Underwriters, and
each such Underwriter agrees, severally and not jointly, to purchase from the
Company, at the purchase price set forth in Schedule I hereto, the principal
amount of the Debentures set forth opposite the name of such Underwriter in
Schedule II hereto.

          5.  Reoffering by Underwriters.  Subject to the terms and conditions
of this Agreement, it is understood that the Underwriters propose to make a
bona fide public offering of the Debentures as soon as practicable after the
execution of this Agreement.

          6.  Time and Place of Closing.  Delivery of the Debentures and
payment therefor shall be made at the offices of Milbank, Tweed, Hadley &
McCloy, 1 Chase Manhattan Plaza, New York, New York at _____ A.M., New York
Time, on ________, 199_, or such other place, time and date as the
Representatives and the Company may agree upon.  The hour and date of such
delivery and payment are herein called the "Closing Date".  Payment for the
Debentures shall be by certified or official bank check payable to the order of
the Company in New York Clearing House (next day) funds.  The Debentures shall
be delivered to the Representatives for the respective accounts of the
Underwriters registered in such names and in such authorized denominations as
the Representatives may reasonably request in writing not later than 12:30
P.M., New York Time, on the third business day prior to the
<PAGE>   6
                                                                               6



Closing Date, or, to the extent not so requested, registered in the names of
the respective Underwriters in such authorized denominations as the Company
shall determine.  For the purpose of expediting the checking of the Debentures
by the Representatives on behalf of the Underwriters, the Company agrees to
make such Debentures available to the Representatives for such purposes at the
corporate trust office of [Chemical Bank] [State Street Bank and Trust Company]
not later than 2:00 P.M., New York Time, on the business day preceding the
Closing Date, or at such other time and place as may be agreed upon by the
Company and the Representatives.

          If any Underwriter or Underwriters default in its or their
obligations to purchase the Debentures which it or they have agreed to purchase
hereunder and the aggregate principal amount of Debentures which such
defaulting Underwriter or Underwriters agreed but failed to purchase is ten
percent or less of the aggregate principal amount of Debentures set forth in
Schedule II hereto, the other Underwriters shall be obligated severally, in
proportion to their respective commitments to purchase Debentures hereunder, to
purchase the Debentures which such defaulting Underwriter or Underwriters
agreed but failed to purchase.  If any Underwriter or Underwriters so default
and the aggregate principal amount of Debentures with respect to which such
default or defaults occur is more than ten percent of the aggregate principal
amount of Debentures set forth in Schedule II hereto and arrangements
satisfactory to you and the Company for the purchase of such Debentures by
other persons are not made within thirty-six hours after such default, the
Company may, at its option, either (a) terminate this Agreement without
liability on the part of any non-defaulting Underwriter or the Company, except
for expenses to be paid or reimbursed by the Company pursuant to Section 7, or
(b) require each non-defaulting Underwriter to purchase the aggregate principal
amount of Debentures which such Underwriter otherwise agreed to purchase plus
an amount equal to one-ninth thereof.  As used in this Agreement, the term
"Underwriter" includes any person substituted for an Underwriter under this
Section.

          The respective commitments of the several Underwriters for purposes
of this paragraph shall be determined without regard to reduction in the
respective Underwriters' obligations to purchase the principal amount of
Debentures set forth opposite their names in Schedule II hereto.  Nothing
herein will relieve a defaulting Underwriter from liability for its default.

          7.  Covenants of the Company.  The Company agrees that:

          (a)  The Company will prepare the Prospectus as amended or
     supplemented in a form approved by the Representatives and will file such
     Prospectus pursuant to Rule 424(b) under the Act not later than the
     Commission's close of business on the second business day following the
     execution and delivery of this Agreement or, if applicable, such earlier
     time as may be required by Rule 424(b).  The Company will at or prior to
     the Closing Date deliver to each of the Representatives and to counsel for
     the Underwriters one signed copy of the Registration Statement as
     originally filed and of all amendments or supplements thereto (including
     conformed copies of any document filed under the Exchange Act and deemed
     to be incorporated by reference into the Prospectus as amended or
     supplemented), heretofore or hereafter made, including any post-effective
     amendment (in each case including all exhibits filed therewith, except
     exhibits incorporated by reference unless specifically requested),
     including a signed copy of each consent and certificate included therein
     or filed as an exhibit thereto.  As soon as the Company is advised
     thereof, it will advise the Representatives orally (i) when any amendment
     to the Registration Statement has been filed or becomes effective or any
     supplement to the Prospectus or any amended Prospectus has been filed with
     the Commission and (ii) of the issuance of any stop order under the Act
     with respect to the Registration Statement or any suspension of the
     qualification of the Debentures in any jurisdiction, or the institution of
     any proceedings therefor of which the Company shall have received notice,
     and will use its best efforts to prevent the issuance of any such stop
     order or suspension and to secure the prompt removal thereof if issued.
     The Company will deliver to the Underwriters, in accordance with the
     Representatives' instructions, as many copies of the Prospectus as amended
     or supplemented as the Representatives may reasonably request for the
     purposes contemplated by the Act, and will deliver to the Representatives
     as soon as practicable sufficient conformed copies of the Registration
     Statement (including conformed copies of any document filed under the
     Exchange Act and deemed to be incorporated by reference into the
     Prospectus as amended or supplemented) and of all amendments thereto (in
     each case without exhibits) for distribution of one to each Underwriter.

          (b)  The Company will pay all expenses incident to the performance
     of its obligations under this Agreement and will reimburse the
     Underwriters for any expenses up to $9,000 (including fees and
     disbursements of counsel) incurred by them in connection with
     qualification of the Debentures for sale and the preparation of memoranda
     as to Blue Sky qualifications and exemptions and as to eligibility of the
<PAGE>   8
                                                                               8


     Debentures for investment under the laws of such jurisdictions as you
     designate.  The Company shall not, however, be required to pay any amount
     for any expenses of the Representatives or any of the Underwriters except
     as provided in paragraph 4 hereof and except, that in the event this
     Agreement shall be terminated in accordance with the provisions of
     paragraph 8 or 9 hereof, the Company will pay the fees and disbursements
     of counsel for the Underwriters, whose fees and disbursements the
     Underwriters agree to pay in any other event.  The Company shall not in
     any event be liable to any of the several Underwriters for damages on
     account of loss of anticipated profits.

          (c)  If at any time when a prospectus relating to the Debentures is
     required to be delivered under the Act, any event relating to or affecting
     the Company, or of which the Company shall be advised in writing by the
     Representatives, shall occur, which in the opinion of the Company should
     be set forth in a supplement to or an amendment of the Prospectus in order
     to make the Prospectus as amended or supplemented not misleading in the
     light of the circumstances when it is delivered, or which, in your
     opinion, may be necessary in connection with the distribution of the
     Debentures, the Company will forthwith at its expense prepare and furnish
     to the Representatives a reasonable number of copies of a supplement or
     supplements or an amendment or amendments to the Prospectus as amended or
     supplemented which will supplement or amend the Prospectus as amended or
     supplemented or file such documents so that the Prospectus as amended or
     supplemented will not contain any untrue statement of a material fact or
     omit to state any material fact necessary in order to make the statements
     therein, in the light of the circumstances when the Prospectus as amended
     or supplemented is delivered, not misleading.  The Company will continue
     to prepare and file with the Commission in a timely manner all documents
     required to be filed pursuant to the requirements of the Exchange Act and
     the Rules and Regulations.

          (d)  The Company will make generally available to its security
     holders (and shall deliver to the Representatives), as soon as practicable
     but in any event not later than 45 days after the end of its fiscal
     quarter in which the first anniversary date of the effective date of the
     Registration Statement (as such term is defined in Rule 158 under the Act)
     (the "Effective Date") occurs, an earnings statement (which need not be
     audited, unless required so to be under Section 11(a) of the Act) of the
     Company in reasonable detail covering a period of at least twelve
     consecutive months beginning after the Effective Date.

                                                                               9


          (e)  The Company will use its best efforts promptly to do and
     perform all things to be done and performed by it hereunder prior to the
     Closing Date and to satisfy all conditions precedent to the delivery by it
     of the Debentures.

          (f)  The Company will use its best efforts to qualify the Debentures
     for offer and sale under the Blue Sky laws of such states as the
     Representatives may designate and will file such statements or reports as
     are or may be reasonably required by the laws of such states; provided,
     however, that the Company in complying with this paragraph need not
     qualify to do business in any state nor execute a general consent to
     service of process.

          (g)  The Company will apply the proceeds of the sale of the
     Debentures, exclusive of accrued interest, if any, for the purposes set
     forth in the Prospectus as amended or supplemented.

          8.  Conditions of Underwriters' Obligations.  The several
obligations of the Underwriters to purchase and pay for the Debentures shall be
subject to the accuracy of, and compliance with, the representations and
warranties of the Company contained herein, to the performance by the Company
of its obligations to be performed hereunder prior to the Closing Date, and to
the following further conditions:

          (a)  The Prospectus as amended or supplemented in relation to the
     Debentures shall have been filed with the Commission pursuant to Rule
     424(b) within the applicable time period prescribed for such filing by the
     Rules and Regulations; and no stop order suspending the effectiveness of
     the Registration Statement shall be in effect on the Closing Date and no
     proceedings for that purpose shall be pending before, or threatened by,
     the Commission on the Closing Date.  The Representatives shall have
     received, prior to payment for the Debentures, a certificate dated the
     Closing Date and signed by the President, any Vice President or the
     Treasurer of the Company to the effect that no such stop order is in
     effect and that no proceedings for such purpose are pending before, or to
     the knowledge of the Company threatened by, the Commission.

          (b)  On the Closing Date there shall be in full force and effect an
     order of the Public Service Commission of the State of New York
     authorizing the issuance and sale of debt securities, including the
     Debentures, which shall not contain any provision mutually unacceptable to
     the Representatives and the Company by reason of being materially adverse,
     it being understood that no order in
<PAGE>   10
                                                                              10


     effect at the date of this Agreement contains any such unacceptable
     provision.

          (c)  At the Closing Date, the Representatives shall receive a
     favorable opinion from either Robert J. Grey, Esq., General Counsel of the
     Company, or Herbert M. Leiman, Esq., Assistant General Counsel of the
     Company, which opinion shall be satisfactory in form and substance to
     Messrs. Milbank, Tweed, Hadley & McCloy, counsel for the Underwriters, to
     the effect that

               (i)  The Company is a corporation duly organized and validly
          existing, in good standing under the laws of the State of New York,
          and has power and authority (corporate and other) to own its
          property, to carry on its business and to issue the Debentures;

              (ii)  The Agreement has been duly authorized, executed and 
          delivered by the Company;

             (iii)  An order has been adopted by the New York Public Service
          Commission authorizing the issuance and sale of the Debentures and
          the transactions related thereto as contemplated by the Agreement
          and said order is still in full force and effect; and no further
          approval, authorization, consent or other order of any public board
          or body is legally required for the authorization of the issuance
          and sale by the Company of the Debentures under the terms of this
          Agreement except compliance with the provisions of securities or
          Blue Sky laws of certain states in connection with the sale of the
          Debentures to the public in such states;

              (iv)  The execution, delivery and performance of this Agreement,
          the Indenture and the Debentures by the Company and the consummation
          by the Company of the transactions contemplated hereby and thereby
          will not conflict with or result in a breach or violation by the
          Company of any of the terms or provisions of, constitute a default
          by the Company under, or result in the creation or imposition of any
          lien, charge, security interest or encumbrance upon any of the
          assets of the Company pursuant to the terms of, (A) any indenture,
          mortgage, deed of trust, loan agreement, lease or other agreement or
          instrument known to such counsel to which the Company is a party or
          to which it or any of its properties is subject, (B) the Charter or
          by-laws of the Company or (C) any statute, rule or regulation or, to
          the best of such counsel's knowledge, any judgment, decree or order
          of any court or governmental agency or body applicable to the
          Company or any of its properties;
<PAGE>   11
                                                                              11


              (v)  The Indenture conforms to the statements with respect
          thereto contained in the Registration Statement and Prospectus as
          amended or supplemented, has been duly authorized by the Company and
          duly executed and delivered, and is a legal, valid and binding
          agreement of the Company enforceable in accordance with its terms,
          subject, however, as to enforcement, to bankruptcy, insolvency,
          reorganization and other laws of general applicability relating to
          or affecting creditors' rights and to general equity principles.
          The Indenture has been duly qualified under the Trust Indenture Act;

              (vi)  The Debentures conform to the terms of this Agreement and
          to the statements with respect thereto contained in the Registration
          Statement and Prospectus as amended or supplemented and have been
          duly authorized; the Debentures have been duly executed,
          authenticated and delivered and are legal, valid and binding
          obligations of the Company enforceable in accordance with their
          terms and are entitled to the benefits and security afforded by the
          Indenture in accordance with the terms of such Indenture and such
          Debentures;

             (vii)  The Company, to the best of such counsel's knowledge,
          possesses all franchises, licenses, permits, consents and orders of
          governmental and regulatory authorities and political subdivisions
          required for the maintenance and operation of its properties and
          business substantially as now conducted and as described in the
          Registration Statement and the Prospectus as amended or
          supplemented; or, if the Company does not possess all of such
          franchises, licenses, permits, consents and orders, the absence of
          such thereof as the Company does not possess will not, to the best
          of such counsel's knowledge, affect the maintenance and operation of
          such properties and business as a whole substantially as now
          conducted; and

            (viii)  The Registration Statement has become effective under the
          Act and, to the best knowledge of such counsel, no stop order
          suspending the effectiveness of the Registration Statement has been
          issued and no proceedings for that purpose have been instituted or
          are pending or contemplated under the Act, the Registration
          Statement and the Prospectus, and each amendment or supplement
          thereto (including any document incorporated by reference into the
          Prospectus as amended or supplemented), as of their respective
          effective or issue dates, complied as to form in all material
          respects with the requirements of the Act, the
<PAGE>   12
                                                                              12


          Exchange Act and the Trust Indenture Act and the applicable rules
          and regulations of the Commission thereunder; the conditions for use
          of Form S-3, set forth in the General Instructions thereto, have
          been satisfied; such counsel has no reason to believe that either
          the Registration Statement or the Prospectus, or any such amendment
          or supplement (including any document filed under the Exchange Act
          and deemed to be incorporated by reference into the Prospectus as
          amended or supplemented), considered as a whole on the effective
          date of the Registration Statement and on the date hereof, contained
          or contain any untrue statement of material fact or omitted or omit
          to state any material fact required to be stated therein or
          necessary to make the statements therein not misleading; the
          descriptions in the Registration Statement and the Prospectus as
          amended or supplemented of statutes, legal and governmental
          proceedings and contracts and other documents are accurate and
          fairly present the information required to be shown; and such
          counsel does not know of any legal or governmental proceedings
          required to be described in the Prospectus as amended or
          supplemented (or required to be filed under the Exchange Act if upon
          such filing they would be incorporated, in whole or in part, by
          reference in the Prospectus as amended or supplemented) which are
          not described as required, nor of any contracts or documents of a
          character required to be described in the Registration Statement or
          Prospectus as amended or supplemented or to be filed as exhibits to
          the Registration Statement which are not described and filed as
          required; it being understood that such counsel need express no
          opinion as to the financial statements or other financial data
          contained or incorporated by reference in the Registration Statement
          or the Prospectus as amended or supplemented.

          (d)  At the Closing Date, the Representatives shall receive from
    Messrs. Milbank, Tweed, Hadley & McCloy, counsel for the Underwriters,
    such opinion or opinions with respect to the valid existence of the
    Company, the validity of the Debentures, the Registration Statement, the
    Prospectus as amended or supplemented, and other related matters as the
    Representatives may require, and the Company shall have furnished to such
    counsel such documents as they request for the purpose of enabling them to
    pass upon such matters.

          (e)  On the date of this Agreement and on the Closing Date the
    Representatives shall have received from Ernst & Young a letter (with
    copies thereof for each of the Underwriters), which letter shall be
    reasonably satisfactory
<PAGE>   13
                                                                              13


     in form and substance to the Representatives and Messrs. Milbank, Tweed,
     Hadley & McCloy, counsel for the Underwriters, confirming that they are
     independent auditors with respect to the Company within the meaning of the
     Act and the applicable published rules and regulations thereunder, and
     stating in effect that:

               (i)  in their opinion, the audited financial statements and
           schedules incorporated by reference into the Registration Statement
           and the Prospectus as amended or supplemented audited by them comply
           as to form in all material respects with the applicable accounting
           requirements of the Act or the Exchange Act, as applicable, and the
           applicable published rules and regulations of the Commission
           thereunder with respect to a registration statement on Form S-3;

               (ii)  they have read the minutes of the meetings of the
           stockholders and the Board of Directors of the Company, as set forth
           in the minute books or, if not set forth therein, in the form
           prepared by the Secretary of the Company, through a specified date
           not more than five business days prior to the date of the closing,
           read the unaudited financial statements, if any, incorporated by
           reference into the Registration Statement and Prospectus as amended
           or supplemented and also the latest available unaudited interim
           financial statements of the Company and inquired of certain
           officials of the Company responsible for financial and accounting
           matters, and that such officials have stated that:

                    (A)  any unaudited Balance Sheet, Statement of Income and
               Statement of Cash Flows included or incorporated by reference in
               the Registration Statement and Prospectus as amended or
               supplemented complies as to form in all material respects with
               the applicable accounting requirements of the Act and the
               Exchange Act and the published rules and regulations of the
               Commission thereunder, and are in conformity with generally
               accepted accounting principles applied on a basis substantially
               consistent with that of the most recent audited financial
               statements included or incorporated by reference therein,

                    (B)  at the date of the latest available balance sheet read
               by such accountants, there was no change in the capital stock
               (including Common Stock, Preferred Stock and Premium on Capital
               Stock but excluding Capital Stock Expense) or long-term debt of

           Registration Statement, with such dollar amounts, percentages and

     results of operation of the Company, except as reflected in or
     contemplated by the Registration Statement and the Prospectus, and any
     amendments or supplements thereto (including any documents filed under the
     Exchange Act and deemed to be incorporated by reference into the
     Prospectus as amended or supplemented), and since such dates and up to the
     Closing Date there shall have been no material transaction entered into by
     the Company other than transactions disclosed by the Registration
     Statement and the Prospectus, and any amendments or supplements thereto
     (including any documents filed under the Exchange Act and deemed to be
     incorporated by reference into the Prospectus as amended or supplemented),
     and transactions in the ordinary course of business; and at the Closing
     Date the Representatives shall have received a certificate to such

                                                                              16


     effect, signed by the President, any Vice President or the Treasurer of
     the Company.

           (g)  All legal proceedings to be taken in connection with the
     issuance and sale of the Debentures shall have been satisfactory in form
     and substance to Messrs. Milbank, Tweed, Hadley & McCloy.

           In case any of the conditions specified above in this Section 8
shall not have been fulfilled at the Closing Date, this Agreement may be
terminated by the Representatives, by mailing or delivering written notice
thereof to the Company.  Any such termination shall be without liability of any
party to any other party except as otherwise provided in Section 7 hereof.

           9.  Conditions of the Obligation of the Company.  The obligation of
the Company to deliver the Debentures shall be subject to the conditions set
forth in the second clause of the first sentence of paragraph (a) of Section 8
hereof and in paragraph (b) of Section 8 hereof.  In case any of the conditions
specified in this Section 9 shall not have been fulfilled, this Agreement may
be terminated by the Company by mailing or delivering written notice thereof to
the Representatives.  Any such termination shall be without liability of any
party to any other party except as otherwise provided in Section 7 hereof.

           10.  Indemnification.  (a)  The Company agrees to indemnify and hold
harmless each Underwriter and each person who controls any Underwriter within
the meaning of Section 15 of the Act against any and all losses, claims,
damages or liabilities, joint or several, to which they or any of them may
become subject under the Act or any other statute or common law and to
reimburse, as incurred, each such Underwriter and controlling person for any
legal or other expense (including, to the extent hereinafter provided,
reasonable counsel fees) incurred by them in connection with investigating any
such losses, claims, damages or liabilities or in connection with preparing to
defend or defending any actions, insofar as such losses, claims, damages,
liabilities, expenses or actions arise out of or are based upon any untrue
statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus, any preliminary prospectus supplement, the Registration
Statement, the Prospectus as amended or supplemented or any amendment or
supplement thereto (if any amendments or supplements thereto shall have been
furnished) or the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading; PROVIDED, HOWEVER, that the indemnity agreement contained in this
paragraph shall not apply to any such losses, claims, damages, liabilities,
expenses or actions arising out of or based upon any such untrue statement or
alleged untrue statement or any such omission or alleged omission, if such
statement or omission was made in reliance upon

                                                                              17


information furnished herein or in writing to the Company by or on behalf of
any Underwriter, through the Representatives, expressly for use in any
Preliminary Prospectus, any preliminary prospectus supplement, the Registration
Statement, the Prospectus as amended or supplemented or any amendment or
supplement thereto; and PROVIDED, FURTHER, that the Company shall not be liable
in any case relating to any Preliminary Prospectus or any preliminary
prospectus supplement to the extent that any such loss, claim, damage,
liability, expense or action arises out of or is based upon the failure of any
Underwriter in connection with a sale of any of the Debentures to any person to
send or give a copy of the Prospectus, as the same may then be supplemented or
amended, to such person with or prior to the written confirmation of the sale
involved so long as the Company shall have fully complied with the last
sentence of Section 7(a) hereof.  The indemnity agreement of the Company
contained in this paragraph and the representations and warranties of the
Company contained in Section 3 hereof shall remain operative and in full force
and effect, regardless of any investigation made by or on behalf of any
Underwriter or any such controlling person, and shall survive the delivery of
the Debentures.  The Underwriters agree promptly to notify the Company of the
commencement of any litigation or proceedings against them or any of them, or
any such controlling person, in connection with the sale of the Debentures or
with any Preliminary Prospectus, any preliminary prospectus supplement, the
Registration Statement, the Prospectus as amended or supplemented or any
amendment or supplement thereto.

           (b)  Each Underwriter agrees to indemnify and hold harmless the
Company, its officers and directors, each other Underwriter, and each person
who controls any thereof within the meaning of Section 15 of the Act, against
any and all losses, claims, damages or liabilities, joint or several, to which
they or any of them become subject under the Act or any other statute or common
law and to reimburse each of them for any legal or other expenses (including,
to the extent hereinafter provided, reasonable counsel fees) incurred by them
in connection with investigating any such losses, claims, damages or
liabilities or in connection with defending any actions, insofar as such
losses, claims, damages, liabilities, expenses or actions arise out of or are
based upon (i) any untrue statement or alleged untrue statement of a material
fact contained in any Preliminary Prospectus, any preliminary prospectus
supplement, the Registration Statement, the Prospectus as amended or
supplemented or any amendment or supplement thereto (if any amendments or
supplements thereto shall have been furnished) or (ii) the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, if such statement or
omission was made in reliance upon information furnished herein or in writing
to the Company by or on behalf of such Underwriter, through the
<PAGE>   18
                                                                              18


Representatives, expressly for use in any Preliminary Prospectus, any
preliminary prospectus supplement, the Registration Statement, the Prospectus
as amended or supplemented or any amendment or supplement thereto.  The
indemnity agreement of the respective Underwriters contained in this paragraph
shall remain operative and in full force and effect, regardless of any
investigation made by or on behalf of the Company, or any such other
Underwriter or any such controlling person, and shall survive the delivery of
the Debentures.  The Company agrees promptly to notify the Representatives of
the commencement of any litigation or proceedings against the Company or any of
its officers or directors or against any such controlling person in connection
with the sale of the Debentures or with any Preliminary Prospectus, any
preliminary prospectus supplement, the Registration Statement, the Prospectus
as amended or supplemented or any amendment or supplement thereto.

           (c)  The Company and each of the Underwriters agree that, upon
receipt of notice of the commencement of any action against the Company or any
person controlling the Company, or against such Underwriter or any person
controlling such Underwriter, in respect of which indemnity may be sought on
account of any indemnity agreement contained herein, it will promptly give
written notice of the commencement thereof to the party or parties against whom
indemnity shall be sought hereunder, but the omission so to notify such
indemnifying party or parties of any such action shall not relieve such
indemnifying party or parties from any liability which it or they may have to
the indemnified party (i) to the extent the indemnifying party was not
materially prejudiced by such omission or (ii) otherwise than on account of
such indemnity agreement.  In case such notice of any such action shall be so
given such indemnifying party shall be entitled to participate at its own
expense in the defense or, if it so elects, to assume (in conjunction with any
other indemnifying parties) the defense of such action, in which event such
defense shall be conducted by counsel chosen by such indemnifying party (or
parties) and satisfactory to the indemnified party or parties who shall be
defendant or defendants in such action; provided, however, if the defendants in
any such action include both the indemnified party and the indemnifying party
and the indemnified party shall have reasonably concluded that there may be
legal defenses available to it and/or other indemnified parties which are
different from or additional to those available to the indemnifying party, the
indemnified party or parties shall have the right to select separate counsel to
assume such legal defenses and to otherwise participate in the defense of such
action on behalf of such indemnified party or parties.  Upon receipt of notice
from the indemnifying party to such indemnified party of its election so to
assume the defense of such action and approval by the indemnified party of
counsel, the indemnifying party will not be liable to such indemnified party
under this Section 10 for any legal or other expenses
<PAGE>   19
                                                                              19


subsequently incurred by such indemnified party in connection with the defense
thereof other than reasonable costs of investigation unless (i) the indemnified
party shall have employed such counsel in connection with the assumption of
legal defenses in accordance with the proviso to the next preceding sentence
(it being understood, however, that the indemnifying party shall not be liable
for the expenses of more than one separate counsel, approved by the
Representatives in the case of paragraph (a) of this Section 10, representing
the indemnified parties under paragraph (a) or (b) of this Section 10, as the
case may be, who are parties to such action), (ii) the indemnifying party shall
not have employed counsel satisfactory to the indemnified party to represent
the indemnified party within a reasonable time after notice of commencement of
the action or (iii) the indemnifying party has authorized the employment of
counsel for the indemnified party at the expense of the indemnifying party.

           (d)  If the indemnification provided for in this Section 10 shall
for any reason be unavailable to an indemnified party under paragraphs (a) or
(b) of this Section 10 in respect of any loss, claim, damage or liability, or
any action in respect thereof, referred to therein, then each indemnifying
party shall, in lieu of indemnifying such indemnified party, contribute to the
amount paid or payable by such indemnified party as a result of such loss,
claim, damage or liability, or action in respect thereof, (i) in such
proportion as shall be appropriate to reflect the relative benefits received by
the Company on the one hand and the Underwriters on the other from the offering
of the Debentures or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause (i) above but also the
relative fault of the Company on the one hand and the Underwriters on the other
with respect to the statements or omissions which resulted in such loss, claim,
damage or liability, or action in respect thereof, as well as any other
relevant equitable considerations.  The relative benefits received by the
Company on the one hand and the Underwriters on the other with respect to such
offering shall be deemed to be in the same proportion as the total net proceeds
from the offering of the Debentures (before deducting expenses) received by the
Company bear to the total underwriting discounts and commissions received by
the Underwriters with respect to such offering, in each case as set forth in
the table on the cover page of the Prospectus.  The relative fault shall be
determined by reference to whether the untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact relates
to information supplied by the Company or the Underwriters, the intent of the
parties and their relative knowledge, access to information and opportunity to
correct or prevent such statement or omission.  The Company and the
Underwriters agree that it would not be just and equitable if
<PAGE>   20
                                                                              20


contributions pursuant to this Section 10 were to be determined by pro rata
allocation or by any other method of allocation which does not take into
account the equitable considerations referred to herein.  The amount paid or
payable by an indemnified party as a result of the loss, claim, damage or
liability, or action in respect thereof, referred to above in this Section 10
shall be deemed to include, for purposes of this Section 10, any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim.  Notwithstanding the
provisions of this Section 10, no Underwriter shall be required to contribute
any amount in excess of the amount by which the total price at which the
Debentures underwritten by it and distributed to the public were offered to the
public exceeds the amount of any damages which such Underwriter has otherwise
paid or becomes liable to pay by reason of any untrue or alleged untrue
statement or omission or alleged omission.  No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation.  The Underwriters' obligations to contribute as provided in
this paragraph (d) are several in proportion to their respective underwriting
obligations and not joint.

           (e)  The agreements contained in this Section 10, the
representations and warranties of the Company in Section 3 hereof and the
agreements of the Company in Section 7 hereof shall survive the delivery of the
Debentures.  The agreements contained in this Section 10, the representations
and warranties of the Company in Section 3 hereof and the agreements of the
Company in Section 7(b) hereof shall remain in full force and effect,
regardless of any termination or cancellation of this Agreement or any
investigation made by or on behalf of any indemnified party.

           11.  Termination.  This Agreement may be terminated at any time
prior to the Closing Date by the Representatives with the consent of a majority
in interest of the Underwriters including yourselves upon notice thereof to the
Company, if prior to such time (a) the Company has failed, refused or been
unable to perform any agreement on its part to be performed hereunder, (b) any
other condition of the Underwriters' obligations hereunder is not fulfilled,
(c) there shall have occurred any general suspension of trading in securities
on the New York Stock Exchange or the American Stock Exchange or there shall
have been established by the New York Stock Exchange or the American Stock
Exchange or by the Commission or by any federal or state agency or by the
decision of any court any limitation on prices for such trading or any
restrictions on the distribution of securities, (d) a banking moratorium shall
have been declared either by federal or New York State authorities, (e) an
outbreak or escalation of hostilities involving the United States shall have
<PAGE>   21
                                                                              21


occurred or there shall have been a declaration by the United States of a
national emergency or war or (f) there shall have occurred such a material
adverse change in general economic, political or financial conditions, or the
effect of international conditions on the financial markets in the United
States is such, as to make it impracticable or inadvisable, in the judgment of
a majority in interest of the Underwriters, to proceed with the delivery of the
Debentures.  Any termination hereof pursuant to this Section 11 shall be
without liability of any party to any other party except as otherwise provided
in Section 7 hereof.

           12.  Information Furnished by Underwriters.  The statements set
forth in the last paragraph on the cover page, the paragraph containing
stabilization information on the inside front cover page and the statements
under the caption "Underwriting" in any Prospectus as amended or supplemented
constitute the only written information furnished by or on behalf of any
Underwriter referred to in paragraph (b) of Section 3 hereof and in paragraphs
(a) and (b) of Section 10 hereof.

           13.  Miscellaneous.  The validity and interpretation of this
Agreement shall be governed by the laws of the State of New York.  This
Agreement shall inure to the benefit of the Company, the Underwriters and, with
respect to the provisions of Section 10 hereof, each controlling person
referred to in said Section 10, and their respective successors, assigns,
executors and administrators.  Nothing in this Agreement is intended or shall
be construed to give to any other person, firm or corporation any legal or
equitable right, remedy or claim under or in respect of this Agreement or any
provisions herein contained.  The term "successors" as used in this Agreement
shall not include any purchaser, as such purchaser, of any of the Debentures
from any of the Underwriters.

           14.  Notices.  All communications hereunder shall be in writing or
by telegram and, if to the Underwriters, shall be mailed or delivered to the
Representatives c/o Lehman Brothers Inc., 3 World Financial Center, New York,
New York 10285-1100, attention:  Syndicate Department; if to the Company, shall
be mailed or delivered to it at 175 East Old Country Road, Hicksville, New York

     the form heretofore delivered or to be delivered to the Representatives
     and, excluding exhibits to the Registration Statement, to the
     Representatives for each of the other Underwriters, if any, have been

     defined below) of the Commission under the Act is hereinafter called a
     "Preliminary Prospectus"; the prospectus relating to the Stock, in the
     form in which it has most recently been filed, or transmitted for filing,

     Preliminary Prospectus or the Prospectus shall be deemed to refer to and
     include the documents incorporated by reference therein pursuant to the
     applicable form under the Act, as of the date of such
<PAGE>   3
                                                                               3

     any amendment or supplement to any Preliminary Prospectus or the
     Prospectus shall be deemed to refer to and include any documents filed
     after the date of such Preliminary Prospectus or Prospectus, as the case
     may be, under the Securities Exchange Act of 1934, as amended (the
     "Exchange Act"), and incorporated by reference in such Preliminary
     Prospectus or Prospectus, as the case may be; and any reference to the
     Prospectus as amended or supplemented shall be deemed to refer to the
     Prospectus as amended or supplemented in relation to the Stock in the form
     in which it is filed with the Commission pursuant to Rule 424(b) under the
     Act, including any documents incorporated by reference therein as of the
     date of such filing).  Any reference to "Rules and Regulations" shall mean
     the rules, regulations and releases adopted by the Commission under either
     the Act or the Exchange Act, as applicable.

          The Company will not file any amendment to the Registration Statement
     or any amendment or supplement to any Preliminary Prospectus or
     Prospectus, or file any document under the Exchange Act before the
     termination of the offering of the Stock by the Underwriters if such
     document would be deemed to be incorporated by reference into such
     Preliminary Prospectus or Prospectus, of which the Representatives shall
     not previously have been advised and provided with a copy or to which the
     Representatives shall reasonably object in writing or which shall be
     disapproved by Messrs. Milbank, Tweed, Hadley & McCloy, who are acting as
     counsel on behalf of the Underwriters.

          (b)  The Registration Statement and the Prospectus and any amendment
     or supplement thereto as of their respective effective or issue dates or
     the date on which they were filed with the Commission, as the case may be,
     and as of each Delivery Date (1) contained or will contain, as applicable,

     the requirements of the Act and the Rules and Regulations; and (3) do not
     and will not include any untrue statement of a material fact or omit to

     information furnished to the Company by any Underwriter specifically for
     use therein.

     property or the conduct of their respective businesses requires such
     qualification, and have all power and authority necessary to own or hold
     their respective properties and to conduct the businesses in which they
     are engaged; and none of the subsidiaries of the Company is a "significant
     subsidiary", as such term is defined in Rule 405 of the Rules and

     notes and supporting schedules) included or incorporated by reference in
     the Registration Statement or Prospectus as amended or supplemented
     present fairly the financial condition and operations of the Company at
     the respective dates or for the respective periods to which they apply
     except as otherwise indicated in the Registration Statement or Prospectus
     as amended or supplemented; such financial statements have been prepared
     in each case in accordance with generally accepted accounting principles
     consistently applied throughout the periods involved except as otherwise
     indicated in the Registration Statement and Prospectus as amended or

     Statement or Prospectus as amended or supplemented and whose report

     condition or results of operation of the Company, and since such dates
     there has not been any material transaction entered into by the Company
     other than transactions contemplated by the Registration Statement and
     Prospectus as amended or supplemented and transactions in the ordinary
     course of business, and (ii) there are no legal or governmental
     proceedings pending to which the Company or any of its subsidiaries is a
     party or of which any property or assets of the Company or any of its
     subsidiaries is the subject which, if determined adversely to the Company
     or any of its subsidiaries might have a material adverse effect on the
     consolidated financial position, stockholders' equity, results of
     operations, business or prospects of the Company and its subsidiaries; and
     to the best of the Company's knowledge, no such proceedings are threatened
     or contemplated by governmental authorities or threatened by others.  The
     Company has no material contingent obligation which is not disclosed in
     the Registration Statement and Prospectus as amended or supplemented.

     in accordance with the provisions of its Restated and Amended Certificate
     of Incorporation (the "Charter") and by-laws and applicable law, and the
     shares of Stock have been duly and validly authorized and, when issued and
     delivered against payment therefor as provided herein, will be duly and
     validly issued, fully paid and nonassessable and will have the rights set
     forth in the Charter.  The Stock when issued will conform to the
     description thereof contained in the Registration Statement and the
     Prospectus as amended or supplemented.

          (h)  The execution, delivery and performance of this Agreement by the
     Company and the consummation of the transactions contemplated hereby will
     not conflict with or result in a breach or violation of any of the terms
     or provisions of, or constitute a default under, any indenture, mortgage,

     order, rule or regulation of any court or governmental agency or body
     having jurisdiction over the Company or any of its subsidiaries or any of

          4.  Purchase and Sale.  On the basis of the representations and
warranties herein contained, but subject to the terms and conditions herein set
forth, the Company agrees to issue and sell to each of the Underwriters, and
each such Underwriter agrees, severally and not jointly, to purchase from the
Company, at the purchase price set forth in Schedule I hereto, the number of
shares of Firm Stock set forth opposite the name of such Underwriter in
Schedule II hereto.

          In addition, the Company grants to the Underwriters an option to
purchase the number of shares of Option Stock set forth in Schedule I hereto.
Such option is granted solely for the purpose of covering over-allotments in
the sale of Firm Stock and is exercisable as provided in Section 6 hereof.
Shares of Option Stock shall be purchased severally for the account of the
Underwriters in proportion to the number of shares of Firm Stock set forth
opposite the name of such Underwriters in Schedule II hereto.  The respective
purchase obligations of each Underwriter with respect to the Option Stock shall
be adjusted by the Representatives so that no Underwriter shall be obligated to
purchase Option Stock other than in 100 share amounts.  The purchase price of
both the Firm Stock and any Option Stock is set forth in Schedule I hereto.

          The Company shall not be obligated to deliver any of the Stock to be
delivered on the First Delivery Date or the Second Delivery Date (as
hereinafter defined) except upon payment for all the Stock to be purchased on
such Delivery Date as provided herein.

          5.  Offering of Stock by Underwriters.  Subject to the terms and
conditions of this Agreement, it is understood that the Underwriters propose to
make a bona fide public offering of the Stock as soon as practicable after the
execution of this Agreement.

          6.  Delivery of and Payment for the Stock.  Delivery of and payment
for the Firm Stock shall be made at the office of Lehman Brothers Inc.,
[address], at 10:00 A.M., New York City time, on the fifth full business day
following the date of this Agreement or at such other date or place as shall be
determined by agreement between the Representatives and the Company.  This date
and time are sometimes referred to as the "First Delivery Date."  On the First
Delivery Date, the Company shall deliver or cause to be delivered certificates
representing the Firm Stock to the Representatives for the account of each
Underwriter against payment to or upon the order of the Company of the purchase
price by certified or official bank check or checks payable in New York
Clearing House (next-day) funds.  Time shall be of the essence, and delivery at
the time and place specified pursuant to this Agreement is a further condition
of the obligation of each Underwriter hereunder.  Upon delivery, the Firm Stock
shall be registered in such names and in such denominations as the
<PAGE>   8
                                                                               8


Representatives shall request in writing not less than two full business days
prior to the First Delivery Date.  For the purpose of expediting the checking
and packaging of the certificates for the Firm Stock, the Company shall make
the certificates representing the Firm Stock available for inspection by the
Representatives in New York, New York, not later than 2:00 P.M., New York City
time, on the business day prior to the First Delivery Date.

          At any time on or before the thirtieth day after the date of this
Agreement the option granted in Section 4 may be exercised by written notice
being given to the Company by the Representatives.  Such notice shall set forth
the aggregate number of shares of Option Stock as to which the option is being
exercised, the names in which the shares of Option Stock are to be registered,
the denominations in which the shares of Option Stock are to be issued and the
date and time, as determined by the Representatives, when the shares of Option
Stock are to be delivered; provided, however, that this date and time shall not
be earlier than the First Delivery Date nor earlier than the second business
day after the date on which the option shall have been exercised nor later than
the fifth business day after the date on which the option shall have been
exercised or at such other date or place as shall be determined by agreement
between the Representatives and the Company.  The date and time the shares of
Option Stock are delivered are sometimes referred to as the "Second Delivery
Date" and the First Delivery Date and the Second Delivery Date are sometimes
each referred to as a "Delivery Date".

          Delivery of and payment for the Option Stock shall be made at the
office of Lehman Brothers Inc., [address] (or at such other place as shall be
determined by agreement between the Representatives and the Company) at 10:00
A.M., New York City time, on the Second Delivery Date.  On the Second Delivery
Date, the Company shall deliver or cause to be delivered the certificates
representing the Option Stock to the Representatives for the account of each
Underwriter against payment to or upon the order of the Company of the purchase
price by certified or official bank check or checks payable in New York
Clearing House (next-day) funds.  Time shall be of the essence, and delivery at
the time and place specified pursuant to this Agreement is a further condition
of the obligation of each Underwriter hereunder.  Upon delivery, the Option
Stock shall be registered in such names and in such denominations as the
Representatives shall request in the aforesaid written notice.  For the purpose
of expediting the checking and packaging of the certificates for the Option
Stock, the Company shall make the certificates representing the Option Stock
available for inspection by the Representatives in New York, New York, not
later than 2:00 P.M., New York City time, on the business day prior to the

                                                                               9


          If, on either Delivery Date, any Underwriter defaults in the
performance of its obligations under this Agreement, the remaining
non-defaulting Underwriters shall be obligated to purchase the Stock which the
defaulting Underwriter agreed but failed to purchase on such Delivery Date in
the respective proportions which the number of shares of the Firm Stock set
forth opposite the name of each remaining non-defaulting Underwriter in
Schedule II hereto bears to the total number of shares of the Firm Stock set
forth opposite the names of all the remaining non-defaulting Underwriters in
Schedule II hereto; provided, however, that the remaining non-defaulting
Underwriters shall not be obligated to purchase any of the Stock on such
Delivery Date if the total number of shares of the Stock which the defaulting
Underwriter or Underwriters agreed but failed to purchase on such date exceeds
9.09% of the total number of shares of the Stock to be purchased on such
Delivery Date, and any remaining non-defaulting Underwriter shall not be
obligated to purchase more than 110% of the number of shares of the Stock which
it agreed to purchase on such Delivery Date pursuant to the terms of Section 4.
If the foregoing maximums are exceeded, the remaining non-defaulting
Underwriters, or those other underwriters satisfactory to the Representatives
who so agree, shall have the right, but shall not be obligated, to purchase, in
such proportion as may be agreed upon among them, all the Stock to be purchased
on such Delivery Date.  If the remaining Underwriters or other underwriters
satisfactory to the Representatives do not elect to purchase the shares which
the defaulting Underwriter or Underwriters agreed but failed to purchase on
such Delivery Date, this Agreement (or, with respect to the Second Delivery
Date, the obligation of the Underwriters to purchase, and of the Company to
sell the Option Stock) shall terminate without liability on the part of any
non-defaulting Underwriter or the Company, except that the Company will
continue to be liable for the payment of expenses to the extent set forth in
Section 7(b).  As used in this Agreement, the term "Underwriter" includes, for
all purposes of this Agreement unless the context requires otherwise, any party
not listed in Schedule II hereto who, pursuant to this Section, purchases Stock
which a defaulting Underwriter agreed but failed to purchase.

          Nothing contained herein shall relieve a defaulting Underwriter of
any liability it may have to the Company for damages caused by its default.  If
other underwriters are obligated or agree to purchase the Stock of a defaulting
or withdrawing Underwriter, either the Representatives or the Company may
postpone the First Delivery Date for up to seven full business days in order to
effect any changes that in the opinion of counsel for the Company or counsel
for the Underwriters may be necessary in the Registration Statement, the
Prospectus or in any other document or arrangement.

          7.  Covenants of the Company.  The Company agrees that:

          (a)  The Company will prepare the Prospectus as amended or
     supplemented in a form approved by the Representatives and will file such
     Prospectus pursuant to Rule 424(b) under the Act not later than the
     Commission's close of business on the second business day following the
     execution and delivery of this Agreement or, if applicable, such earlier
     time as may be required by Rule 424(b).  The Company will at or prior to
     the First Delivery Date deliver to each of the Representatives and to
     counsel for the Underwriters one signed copy of the Registration Statement
     as originally filed and of all amendments or supplements thereto
     (including conformed copies of any document filed under the Exchange Act
     and deemed to be incorporated by reference into the Prospectus as amended
     or supplemented), heretofore or hereafter made, including any
     post-effective amendment (in each case including all exhibits filed
     therewith, except exhibits incorporated by reference unless specifically
     requested), including a signed copy of each consent and certificate
     included therein or filed as an exhibit thereto.  As soon as the Company
     is advised thereof, it will advise the Representatives orally (i) when any
     amendment to the Registration Statement has been filed or becomes
     effective or any supplement to the Prospectus or any amended Prospectus
     has been filed with the Commission and (ii) of the issuance of any stop
     order under the Act with respect to the Registration Statement or any
     suspension of the qualification of the Common Stock in any jurisdiction,
     or the institution of any proceedings therefor of which the Company shall
     have received notice, and will use its best efforts to prevent the
     issuance of any such stop order or suspension and to secure the prompt
     removal thereof if issued.  The Company will deliver to the Underwriters,
     in accordance with the Representatives' instructions, as many copies of
     the Prospectus as amended or supplemented as the Representatives may
     reasonably request for the purposes contemplated by the Act, and will
     deliver to the Representatives as soon as practicable sufficient conformed
     copies of the Registration Statement (including conformed copies of any
     document filed under the Exchange Act and deemed to be incorporated by
     reference into the Prospectus as amended or supplemented) and of all
     amendments thereto (in each case without exhibits) for distribution of one
     to each Underwriter.

          (b)  The Company will pay all expenses incident to the performance of
     its obligations under this Agreement and will reimburse the Underwriters

     qualifications and exemptions and as to eligibility of the Stock for
     investment under the laws of such jurisdictions as you designate.  The
     Company shall not, however, be required to pay any amount for any expenses
     of the Representatives or any of the Underwriters except as provided in
     paragraph 4 hereof and except, that in the event this Agreement shall be
     terminated in accordance with the provisions of Section 8 or 9 hereof, the

     Underwriters, whose fees and disbursements the Underwriters agree to pay
     in any other event.  The Company shall not in any event be liable to any
     of the several Underwriters for damages on account of loss of anticipated
     profits.

          (c)  If at any time when a prospectus relating to the Stock is
     required to be delivered under the Act, any event relating to or affecting
     the Company, or of which the Company shall be advised in writing by the
     Representatives, shall occur, which in the opinion of the Company should
     be set forth in a supplement to or an amendment of the Prospectus in order
     to make the Prospectus as amended or supplemented not misleading in the
     light of the circumstances when it is delivered, or which, in your
     opinion, may be necessary in connection with the distribution of the
     Stock, the Company will forthwith at its expense prepare and furnish to
     the Representatives a reasonable number of copies of a supplement or
     supplements or an amendment or amendments to the Prospectus as amended or
     supplemented which will supplement or amend the Prospectus as amended or
     supplemented or file such documents so that the Prospectus as amended or
     supplemented will not contain any untrue statement of a material fact or
     omit to state any material fact necessary in order to make the statements
     therein, in the light of the circumstances when the Prospectus as amended
     or supplemented is delivered, not misleading.  The Company will continue
     to prepare and file with the Commission in a timely manner all documents
     required to be filed pursuant to the requirements of the Exchange Act and
     the Rules and Regulations.

          (d)  The Company will make generally available to its security
     holders (and shall deliver to the Representatives), as soon as practicable
     but in any event not later than 45 days after the end of its fiscal
     quarter in which the first anniversary date of the effective date of the
     Registration Statement (as such term is defined in Rule 158 under the Act)
     (the "Effective Date") occurs, an earnings statement (which need not be
     audited, unless required so to be under Section 11(a) of the Act) of the
     Company in reasonable detail covering a period of at least twelve
     consecutive months beginning after the Effective Date.

                                                                              12


          (e)  For a period of 180 days from the date of the Prospectus as
     amended or supplemented, the Company will not offer for sale, sell or
     otherwise dispose of, directly or indirectly, any shares of Common Stock
     (other than the Stock and shares issued pursuant to the Company's Employee
     Stock Purchase Plan, Automatic Dividend Reinvestment Plan, employee
     benefit plans, qualified stock option plans or other employee compensation
     plans existing on the date hereof or pursuant to currently outstanding
     options, warrants or rights), or sell or grant options, rights or warrants
     with respect to any shares of Common Stock (other than the grant of
     options pursuant to options plans existing on the date hereof), without
     the prior written consent of the Representatives.

          (f)  The Company will use its best efforts promptly to do and perform
     all things to be done and performed by it hereunder prior to each Delivery
     Date and to satisfy all conditions precedent to the delivery by it of the
     Stock.

          (g)  The Company will use its best efforts to qualify the Stock for
     offer and sale under the Blue Sky laws of such states as the
     Representatives may designate and will file such statements or reports as
     are or may be reasonably required by the laws of such states; provided,
     however, that the Company in complying with this paragraph need not
     qualify to do business in any state nor execute a general consent to
     service of process.

          (h)  The Company will apply the proceeds of the sale of the Stock for
     the purposes set forth in the Prospectus as amended or supplemented.

          8.  Conditions of Underwriters' Obligations.  The several obligations
of the Underwriters to purchase and pay for the Stock shall be subject to the
accuracy, when made and on each Delivery Date, of, and compliance with, the
representations and warranties of the Company contained herein, to the
performance by the Company of its obligations to be performed hereunder prior
to each Delivery Date, and to the following further terms and conditions:

          (a)  The Prospectus as amended or supplemented in relation to the
     Stock shall have been filed with the Commission pursuant to Rule 424(b)
     within the applicable time period prescribed for such filing by the Rules
     and Regulations; and no stop order suspending the effectiveness of the
     Registration Statement shall be in effect on each Delivery Date and no
     proceedings for that purpose shall be pending before, or threatened by,
     the Commission on each Delivery Date; and any request of the Commission
     for inclusion of additional information in the Registration
<PAGE>   13
                                                                              13


     Statement or the Prospectus or otherwise shall have been complied with.

          The Representatives shall have received, prior to any payment for the
     Stock, a certificate dated the respective Delivery Date and signed by the
     President, any Vice President or the Treasurer of the Company to the
     effect that no such stop order is in effect and that no proceedings for
     such purpose are pending before, or to the knowledge of the Company
     threatened by, the Commission.

          (b)  No Underwriter shall have discovered and disclosed to the
     Company on or prior to such Delivery Date that the Registration Statement
     or the Prospectus or any amendment or supplement thereto contains an
     untrue statement of a fact which, in the opinion of Milbank, Tweed, Hadley
     & McCloy, counsel for the Underwriters, is material or omits to state a
     fact which, in the opinion of such counsel, is material and is required to
     be stated therein or is necessary to make the statements therein not
     misleading.

          (c)  On each Delivery Date there shall be in full force and effect an
     order of the Public Service Commission of the State of New York
     authorizing the issuance and sale of the Stock which shall not contain any
     provision mutually unacceptable to the Representatives and the Company by
     reason of being materially adverse, it being understood that no order in
     effect at the date of this Agreement contains any such unacceptable
     provision.

          (d)  At each Delivery Date, the Representatives shall receive a
     favorable opinion from either Robert J. Grey, Esq., General Counsel of the
     Company, or Herbert M. Leiman, Esq., Assistant General Counsel of the
     Company, which opinion shall be satisfactory in form and substance to
     Messrs. Milbank, Tweed, Hadley & McCloy, counsel for the Underwriters, to
     the effect that --

               (i)  The Company and each of its subsidiaries is a corporation
          duly organized and validly existing, in good standing under the laws
          of the State of New York, are duly qualified to do business and are
          in good standing as foreign corporations in each jurisdiction in
          which their respective ownership or lease of property or the conduct
          of their business requires such qualifications, with power and
          authority (corporate and other) to own their property, to carry on
          their business and to issue the Stock;

              (ii)  The Agreement has been duly authorized, executed and 
          delivered by the Company;
<PAGE>   14
                                                                              14


             (iii)  The Company has an authorized capitalization as set forth
          in the Prospectus, and all of the issued shares of capital stock of
          the Company, including the shares of Stock being delivered on such
          Delivery Date, have been duly and validly authorized and issued, are
          fully paid and nonassessable and conform to the description thereof
          contained in the Registration Statement and the Prospectus as amended
          or supplemented;

              (iv)  There are no preemptive or other rights to subscribe for or
          to purchase, nor any restriction upon the voting or transfer of, any
          shares of the Stock pursuant to the Company's Charter or by-laws or
          any agreement or other instrument known to such counsel;

               (v)  An order has been adopted by the Public Service Commission
          of the State of New York authorizing the issuance and sale of the
          Stock and the transactions related thereto as contemplated by the
          Agreement and said order is still in full force and effect; and no
          further approval, authorization, consent or other order of any court,
          governmental agency, public board or body is legally required for the
          authorization of the issuance and sale by the Company of the Stock
          under the terms of this Agreement except compliance with the
          provisions of securities or Blue Sky laws of certain states in
          connection with the sale of the Stock to the public in such states;

              (vi)  The Company has good and marketable title in fee simple to
          all real property owned by them, in each case free and clear of all
          liens, encumbrances and defects except such as are described in the
          Prospectus or such as do not materially affect the value of such
          property and do not materially interfere with the use made and
          proposed to be made of such property by the Company; and all real
          property and buildings held under lease by the Company are held by
          them under valid, subsisting and enforceable leases, with such
          exceptions as are not material and do not interfere with the use made
          and proposed to be made of such property and buildings by the
          Company.  In giving the above opinion, such counsel may state that no
          examination of record titles for the purpose of such opinion has been
          made, and that he is relying upon a general review of the titles of
          the Company, upon opinions of local counsel and abstracts, reports
          and policies of title companies rendered or issued at or subsequent
          to the time of acquisition of such property by the Company, upon
          opinions of counsel to the lessors of such property and, in respect
          of matters of fact, upon certificates of officers of the Company,
          provided that such counsel
<PAGE>   15
                                                                              15


          shall state that he believes that both the Underwriters and he are
          justified in relying upon such opinions, abstracts, reports, policies
          and certificates;

             (vii)  The execution, delivery and performance of this Agreement
          and the Stock by the Company and the consummation by the Company of
          the transactions contemplated hereby will not conflict with or result
          in a breach or violation by the Company of any of the terms or
          provisions of, constitute a default by the Company under, or result
          in the creation or imposition of any lien, charge, security interest
          or encumbrance upon any of the assets of the Company pursuant to the
          terms of, (A) any indenture, mortgage, deed of trust, loan agreement,
          lease or other agreement or instrument known to such counsel to which
          the Company is a party or to which it or any of its properties is
          subject, (B) the Charter or by-laws of the Company or (C) any
          statute, rule or regulation or, to the best of such counsel's
          knowledge, any judgment, decree or order of any court or governmental
          agency or body applicable to the Company or any of its properties;

            (viii)  The Company, to the best of such counsel's knowledge,
          possesses all franchises, licenses, permits, consents and orders of
          governmental and regulatory authorities and political subdivisions
          required for the maintenance and operation of its properties and
          business substantially as now conducted and as described in the
          Registration Statement and the Prospectus as amended or supplemented;
          or, if the Company does not possess all of such franchises, licenses,
          permits, consents and orders, the absence of such thereof as the
          Company does not possess will not, to the best of such counsel's
          knowledge, affect the maintenance and operation of such properties
          and business as a whole substantially as now conducted; and

              (ix)  The Registration Statement has become effective under the
          Act and, to the best knowledge of such counsel, no stop order
          suspending the effectiveness of the Registration Statement has been
          issued and no proceedings for that purpose have been instituted or
          are pending or contemplated under the Act, the Registration Statement
          and the Prospectus, and each amendment or supplement thereto
          (including any document incorporated by reference into the Prospectus
          as amended or supplemented), as of their respective effective or
          issue dates, complied as to form in all material respects with the
          requirements of the Act and the Exchange Act and the Rules and
          Regulations; the conditions for use of Form S-3, set forth in the
          General Instructions thereto, have been satisfied; such
<PAGE>   16
                                                                              16


          counsel has no reason to believe that either the Registration
          Statement or the Prospectus, or any such amendment or supplement
          (including any document filed under the Exchange Act and deemed to be
          incorporated by reference into the Prospectus as amended or
          supplemented), considered as a whole on the effective date of the
          Registration Statement and on the date hereof, contained or contain
          any untrue statement of material fact or omitted or omit to state any
          material fact required to be stated therein or necessary to make the
          statements therein not misleading; the descriptions in the
          Registration Statement and the Prospectus as amended or supplemented
          of statutes, legal and governmental proceedings and contracts and
          other documents are accurate and fairly present the information
          required to be shown; and such counsel does not know of any legal or
          governmental proceedings required to be described in the Prospectus
          as amended or supplemented (or required to be filed under the
          Exchange Act if upon such filing they would be incorporated, in whole
          or in part, by reference in the Prospectus as amended or
          supplemented) which are not described as required, nor of any
          contracts or documents of a character required to be described in the
          Registration Statement or Prospectus as amended or supplemented or to
          be filed as exhibits to the Registration Statement which are not
          described and filed as required; it being understood that such
          counsel need express no opinion as to the financial statements or
          other financial data contained or incorporated by reference in the
          Registration Statement or the Prospectus as amended or supplemented;

               [(x)  The statements contained in the Prospectus under the
          caption ___, insofar as they describe federal statutes, rules and
          regulations, constitute a fair summary thereof and the opinion of
          such counsel filed as Exhibit 8 to the Registration Statement is
          confirmed and the Underwriters may rely upon such opinion as if it
          were addressed to them;] and

               (xi)  To the best of such counsel's knowledge, there are no
          contracts, agreements or understandings between the Company and any
          person granting such person the right to require the Company to file
          a registration statement under the Act with respect to any securities
          of the Company owned or to be owned by such person or to require the
          Company to include such securities in the securities registered
          pursuant to the Registration Statement or in any securities being
          registered pursuant to any other registration statement filed by the
          Company under the Act.

          (e)  At each Delivery Date, the Representatives shall receive from
     Messrs. Milbank, Tweed, Hadley & McCloy, counsel for the Underwriters,
     such opinion or opinions with respect to the valid existence of the
     Company, the validity of the Stock, the Registration Statement, the
     Prospectus as amended or supplemented, and other related matters as you
     may require, and the Company shall have furnished to such counsel such
     documents as they request for the purpose of enabling them to pass upon
     such matters.

          (f)  On the date of this Agreement and on each Delivery Date the
     Representatives shall have received from Ernst & Young a letter (with
     copies thereof for each of the Underwriters), which letter shall be
     reasonably satisfactory in form and substance to the Representatives and
     Messrs. Milbank, Tweed, Hadley & McCloy, counsel for the Underwriters,
     confirming that they are independent auditors with respect to the Company
     within the meaning of the Act and the applicable published rules and
     regulations thereunder, and stating in effect that:

          as to form in all material respects with the applicable accounting
          requirements of the Act or the Exchange Act, as applicable, and the
          applicable published rules and regulations of the Commission
          thereunder with respect to a registration statement on Form S-3;

               (ii)  they have read the minutes of the meetings of the
          stockholders and the Board of Directors of the Company, as set forth
          in the minute books or, if not set forth therein, in the form
          prepared by the Secretary of the Company, through a specified date
          not more than five business days prior to the Delivery Date, read the
          unaudited financial statements, if any, incorporated by reference
          into the Registration Statement and Prospectus as amended or
          supplemented and also the latest available unaudited interim
          financial statements of the Company and inquired of certain officials
          of the Company responsible for financial and accounting matters, and
          that such officials have stated that:

                    (A)  any unaudited Balance Sheet, Statement of Income and
               Statement of Cash Flows included or incorporated by reference in
               the Registration Statement and Prospectus as amended or
               supplemented complies as to form in all material respects with
               the applicable accounting requirements of the Act and the

               the published rules and regulations of the Commission
               thereunder, and are in conformity with generally accepted
               accounting principles applied on a basis substantially
               consistent with that of the most recent audited financial
               statements included or incorporated by reference therein,

                    (B)  at the date of the latest available balance sheet read
               by such accountants, there was no change in the capital stock
               (including Common Stock, Preferred Stock and Premium on Capital

               Shareowners' Equity as compared with amounts shown on the latest
               balance sheet included or incorporated by reference in the
               Registration Statement and Prospectus as amended or

          Statement and Prospectus as amended or supplemented, except in all
          instances (i) for changes or decreases that the Registration
          Statement and Prospectus as amended or supplemented discloses have
          occurred or may occur, (ii) for payment of maturing installments of

          described in such letter, identifying the same and specifying the
          amount thereof; and

               (iv)  they have compared certain dollar amounts (and percentages
          and other financial data derived from such dollar amounts) disclosed
          in, or incorporated by reference into, the Registration Statement and
          Prospectus as amended or supplemented or in Exhibits to the
          Registration Statement, with such dollar amounts, percentages and
          other financial information contained in the general accounting
          records of the Company or derived directly from such records by
          analysis or computation, and have found such dollar amounts,

     material adverse change in the business, properties or financial condition
     or results of operation of the Company, except as reflected in or
     contemplated by the Registration Statement and the Prospectus, and any
     amendments or supplements thereto (including any documents filed under the
     Exchange Act and deemed to be incorporated by reference into the
     Prospectus as amended or supplemented), and since such dates and up to
     such Delivery Date there shall have been no material transaction entered

     deemed to be incorporated by reference into the Prospectus as amended or
     supplemented), and transactions in the ordinary course of business; and at
     such Delivery Date the Representatives shall have received a certificate
     to such effect, signed by the President, any Vice President or the
     Treasurer of the Company.

          (h)  Subsequent to the execution and delivery of this Agreement and
     prior to each Delivery Date (i) no downgrading shall have occurred in the
     rating accorded the Company's debt securities or preferred stock by any
     "nationally recognized statistical rating organization", as that term is
     defined by the Commission for purposes of Rule 436(g)(2) of the Rules and
     Regulations and (ii) no such organization shall have publicly announced
     that it has under surveillance or review, with possible negative
     implications, its rating of any of the Company's debt securities or
     preferred stock.

          (i)  All legal proceedings to be taken and all opinions, letters,
     evidence and certificates mentioned above or elsewhere in this Agreement
     in connection with the issuance and sale of the Stock shall have been
     satisfactory in form and substance to Messrs. Milbank, Tweed, Hadley &
     McCloy.

          In case any of the conditions specified above in this Section 8 shall
not have been fulfilled at each Delivery Date, this Agreement may be terminated
by the Representatives, with the consent of the Underwriters including
yourselves who have agreed to purchase in the aggregate fifty percent or more
of the Stock, by mailing or delivering written notice thereof to the Company.
Any such termination shall be without liability of any party to any other party
except as otherwise provided in Section 7 hereof.

          9.  Conditions of the Obligation of the Company.  The obligation of
the Company to deliver the Stock shall be subject to the conditions set forth
in the second clause of the first sentence of paragraph (a) of Section 8 hereof
and in paragraph (c) of Section 8 hereof.  In case any of the conditions
specified in this Section 9 shall not have been fulfilled, this Agreement may
be terminated by the Company by mailing or delivering written notice thereof to
the Representatives.  Any such termination shall be without liability of any
party to any other party except as otherwise provided in Section 7 hereof.

          10.  Indemnification.  (a)  The Company agrees to indemnify and hold
harmless each Underwriter and each person who controls any Underwriter within
the meaning of Section 15 of the Act against any and all losses, claims,
damages or liabilities, joint or several, to which they or any of them may
become subject under the Act or any other statute or common law and to
reimburse, as incurred each such Underwriter and controlling person for any
legal or other expense (including, to the extent hereinafter provided,
reasonable counsel fees) incurred by them in connection with investigating any
such losses, claims, damages or liabilities or in connection with preparing to
defend or defending any actions, insofar as such losses, claims, damages,
liabilities, expenses or actions arise out of or are based upon (i) any untrue
statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus, any preliminary prospectus supplement, the Registration
Statement, the Prospectus as amended or supplemented or any amendment or
supplement thereto (if any amendments or supplements thereto shall have been
furnished) or (ii) the omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading; provided, however, that the indemnity agreement contained in
this paragraph shall not apply to any such losses, claims, damages,
liabilities, expenses or actions arising out of or based upon any such untrue
statement or alleged untrue statement or any such omission or alleged omission,
if such statement or omission was made in reliance upon information furnished
herein or in writing to the Company by or on behalf of any Underwriter, through
the Representatives, expressly for use in any Preliminary Prospectus, any
preliminary prospectus supplement, the Registration Statement, the Prospectus
as amended or supplemented or any amendment or supplement thereto; and
provided, further, that the Company shall not be liable in any case relating to
any Preliminary Prospectus or any preliminary prospectus supplement to the
extent that any such loss, claim, damage, liability, expense or action arises
out of or is based upon the failure of any Underwriter in connection with a
sale of any of the Stock to any person to send or give a copy of the
Prospectus, as the same may then be supplemented or amended, to such person
with or prior to the written confirmation of the sale involved so long as the
Company shall have fully complied with the last sentence of Section 7(a)
hereof.  The indemnity agreement of the Company contained in this paragraph and
the representations and warranties of the Company contained in Section 3 hereof
shall remain operative and in full force and effect, regardless of any
investigation made by or on behalf of any Underwriter or any such controlling
person, and shall survive the delivery of the Stock.  The Underwriters agree
promptly to notify the Company of the commencement of any litigation or
proceedings against them or any of them, or any such controlling person, in
connection with the sale of the Stock or with any Preliminary Prospectus, any
preliminary prospectus supplement,
<PAGE>   22
                                                                              22


the Registration Statement, the Prospectus as amended or supplemented or any
amendment or supplement thereto.

          (b)  Each Underwriter severally and not jointly agrees to indemnify
and hold harmless the Company, its officers and directors, each other
Underwriter, and each person who controls any thereof within the meaning of
Section 15 of the Act, against any and all losses, claims, damages or
liabilities, joint or several, to which they or any of them become subject
under the Act or any other statute or common law and to reimburse each of them
for any legal or other expenses (including, to the extent hereinafter provided,
reasonable counsel fees) incurred by them in connection with investigating any
such losses, claims, damages or liabilities or in connection with defending any
actions, insofar as such losses, claims, damages, liabilities, expenses or
actions arise out of or are based upon (i) any untrue statement or alleged
untrue statement of a material fact contained in any Preliminary Prospectus,
any preliminary prospectus supplement, the Registration Statement, the
Prospectus as amended or supplemented or any amendment or supplement thereto
(if any amendments or supplements thereto shall have been furnished) or (ii)
the omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading,
if such statement or omission was made in reliance upon information furnished
herein or in writing to the Company by or on behalf of such Underwriter,
through the Representatives, expressly for use in any Preliminary Prospectus,
any preliminary prospectus supplement, the Registration Statement, the
Prospectus as amended or supplemented or any amendment or supplement thereto.
The indemnity agreement of the respective Underwriters contained in this
paragraph shall remain operative and in full force and effect, regardless of
any investigation made by or on behalf of the Company, or any such other
Underwriter or any such controlling person, and shall survive the delivery of
the Stock.  The Company agrees promptly to notify the Representatives of the
commencement of any litigation or proceedings against the Company or any of its
officers or directors or against any such controlling person in connection with
the sale of the Stock or with any Preliminary Prospectus, any preliminary
prospectus supplement, the Registration Statement, the Prospectus as amended or
supplemented or any amendment or supplement thereto.

          (c)  The Company and each of the Underwriters agree that, upon
receipt of notice of the commencement of any action against the Company or any
person controlling the Company, or against such Underwriter or any person
controlling such Underwriter, in respect of which indemnity may be sought on
account of any indemnity agreement contained herein, it will promptly give
written notice of the commencement thereof to the party or parties against whom
indemnity shall be sought hereunder, but the omission so to notify such
indemnifying
<PAGE>   23
                                                                              23


party or parties of any such action shall not relieve such indemnifying party
or parties from any liability which it or they may have to the indemnified
party (i) to the extent the indemnifying party was not materially prejudiced by
such omission or (ii) otherwise than on account of such indemnity agreement.
In case such notice of any such action shall be so given such indemnifying
party shall be entitled to participate at its own expense in the defense or, if
it so elects, to assume (in conjunction with any other indemnifying parties)
the defense of such action, in which event such defense shall be conducted by
counsel chosen by such indemnifying party (or parties) and satisfactory to the
indemnified party or parties who shall be defendant or defendants in such
action; provided, however, if the defendants in any such action include both
the indemnified party and the indemnifying party and the indemnified party
shall have reasonably concluded that there may be legal defenses available to
it and/or other indemnified parties which are different from or additional to
those available to the indemnifying party, the indemnified party or parties
shall have the right to select separate counsel to assume such legal defenses
and to otherwise participate in the defense of such action on behalf of such
indemnified party or parties.  Upon receipt of notice from the indemnifying
party to such indemnified party of its election so to assume the defense of
such action and approval by the indemnified party of counsel, the indemnifying
party will not be liable to such indemnified party under this Section 10 for
any legal or other expenses subsequently incurred by such indemnified party in
connection with the defense thereof other than reasonable costs of
investigation unless (i) the indemnified party shall have employed such counsel
in connection with the assumption of legal defenses in accordance with the
proviso to the next preceding sentence (it being understood, however, that the
indemnifying party shall not be liable for the expenses of more than one
separate counsel, approved by the Representatives in the case of paragraph (a)
of this Section 10, representing the indemnified parties under paragraph (a) or
(b) of this Section 10, as the case may be, who are parties to such action),
(ii) the indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of commencement of the action or (iii) the indemnifying party has
authorized the employment of counsel for the indemnified party at the expense
of the indemnifying party.

          (d)  If the indemnification provided for in this Section 10 shall for
any reason be unavailable to an indemnified party under paragraphs (a) or (b)
of this Section 10 in respect of any loss, claim, damage or liability, or any
action in respect thereof, referred to therein, then each indemnifying party
shall, in lieu of indemnifying such indemnified party, contribute to the amount
paid or payable by such indemnified party as a result of such loss, claim,
damage or liability, or action in respect thereof, (i) in such proportion as
shall be appropriate to reflect the relative benefits received by the Company
on the one
<PAGE>   24
                                                                              24


hand and the Underwriters on the other from the offering of the Stock or (ii)
if the allocation provided by clause (i) above is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits referred to in clause (i) above but also the relative fault of the
Company on the one hand and the Underwriters on the other with respect to the
statements or omissions which resulted in such loss, claim, damage or
liability, or action in respect thereof, as well as any other relevant
equitable considerations.  The relative benefits received by the Company on the
one hand and the Underwriters on the other with respect to such offering shall
be deemed to be in the same proportion as the total net proceeds from the
offering of the Stock (before deducting expenses) received by the Company bear
to the total underwriting discounts and commissions received by the
Underwriters with respect to such offering, in each case as set forth in the
table on the cover page of the Prospectus.  The relative fault shall be
determined by reference to whether the untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact relates
to information supplied by the Company or the Underwriters, the intent of the
parties and their relative knowledge, access to information and opportunity to
correct or prevent such statement or omission.  The Company and the
Underwriters agree that it would not be just and equitable if contributions
pursuant to this Section 10 were to be determined by pro rata allocation or by
any other method of allocation which does not take into account the equitable
considerations referred to herein.  The amount paid or payable by an
indemnified party as a result of the loss, claim, damage or liability, or
action in respect thereof, referred to above in this Section 10 shall be deemed
to include, for purposes of this Section 10, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim.  Notwithstanding the provisions of this
Section 10, no Underwriter shall be required to contribute any amount in excess
of the amount by which the total price at which the Stock underwritten by it
and distributed to the public were offered to the public exceeds the amount of
any damages which such Underwriter has otherwise paid or becomes liable to pay
by reason of any untrue or alleged untrue statement or omission or alleged
omission.  No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.  The Underwriters'
obligations to contribute as provided in this paragraph (d) are several in
proportion to their respective underwriting obligations and not joint.

          (e)  The agreements contained in this Section 10, the representations
and warranties of the Company in Section 3 hereof and the agreements of the
Company in Section 7 hereof shall survive the delivery of the Stock.  The
agreements contained in this Section 10, the representations and warranties of
the Company in Section 3 hereof and the agreements of the Company in
<PAGE>   25
                                                                              25


Section 7(b) hereof shall remain in full force and effect, regardless of any
termination or cancellation of this Agreement or any investigation made by or
on behalf of any indemnified party.

          11.  Termination.  This Agreement may be terminated at any time prior
to each Delivery Date by the Representatives with the consent of a majority in
interest of the Underwriters including yourselves upon notice thereof to the
Company, if prior to such time (a) the Company has failed, refused or been
unable to perform any agreement on its part to be performed hereunder, (b) any
other condition of the Underwriters' obligations hereunder is not fulfilled,
(c) there shall have occurred any general suspension of trading in securities
on the New York Stock Exchange or the American Stock Exchange or there shall
have been established by the New York Stock Exchange or the American Stock
Exchange or by the Commission or by any federal or state agency or by the
decision of any court any limitation on prices for such trading or any
restrictions on the distribution of securities, (d) a banking moratorium shall
have been declared either by federal or New York State authorities, (e) an
outbreak or escalation of hostilities involving the United States shall have
occurred or there shall have been a declaration by the United States of a
national emergency or war or (f) there shall have occurred such a material
adverse change in general economic, political or financial conditions, or the
effect of international conditions on the financial markets in the United
States is such, as to make it impracticable or inadvisable, in the judgment of
a majority in interest of the Underwriters, to proceed with the delivery of the
Stock.  Any termination hereof pursuant to this Section 11 shall be without
liability of any party to any other party except as otherwise provided in
Section 7 hereof.

          12.  Information Furnished by Underwriters.  The statements set forth
in the last paragraph on the cover page, the paragraph containing stabilization
information on the inside front cover page and the statements under the caption
"Underwriting" in any Prospectus as amended or supplemented constitute the only
written information furnished by or on behalf of any Underwriter referred to in
paragraph (b) of Section 3 hereof and in paragraphs (a) and (b) of Section 10
hereof.

          13.  Miscellaneous.  The validity and interpretation of this
Agreement shall be governed by the laws of the State of New York.  This
Agreement shall inure to the benefit of the Company, the Underwriters and, with
respect to the provisions of Section  10 hereof, each controlling person
referred to in said Section 10, and their respective successors, assigns,
executors and administrators.  Nothing in this Agreement is intended or shall
be construed to give to any other person, firm or corporation any legal or
equitable right, remedy or claim under or in respect of this Agreement or any
provisions herein contained.  The term "successors" as used in this Agreement
shall not include any

purchaser, as such purchaser, of any of the Stock from any of the Underwriters.

           3.  Representations and Warranties of the Company.  The Company
represents and warrants to each of the Underwriters, as of the date hereof and
as of the Closing Date (as hereinafter defined), that:

           (a)  The Company has filed with the Securities and Exchange
      Commission (the "Commission") a registration statement on Form S-3 (No.
      33-_____) under the Securities Act of 1933, as amended (the "Act"), for
      the registration of the Stock under the Act.  The various parts of such
      registration statement, including all exhibits thereto and the documents
      incorporated by reference in the prospectus contained therein at the time
      such part of such registration statement became effective, each as
      amended at the time such part of the registration statement became
      effective, are hereinafter called the "Registration Statement"; any
      reference to any amendment to the Registration Statement shall be deemed
      to refer to and include any document filed pursuant to Section 13(a) or
      15(d) of the Exchange Act after the effective date of the Registration
      Statement that is incorporated by reference in the Registration
      Statement).  The Registration Statement and any post-effective amendment
      thereto, each in the form heretofore delivered or to be delivered to the
      Representatives and, excluding exhibits to the Registration Statement, to
      the Representatives for each of the other Underwriters, if any, have been
      declared effective by the Commission in such form.  No other document
      with respect to the Registration Statement or document incorporated by
      reference therein has heretofore been filed or transmitted for filing
      with the Commission, no stop order suspending the effectiveness of the
      Registration Statement has been issued and no proceeding for that purpose
      has been initiated or threatened by the Commission (any preliminary
      prospectus included in the Registration Statement or filed with the
      Commission pursuant to Rule 424(a) of the rules and regulations of the
      Commission under the Act is hereinafter called a "Preliminary
      Prospectus"; the prospectus relating to the Stock, in the form in which
      it has most recently been filed with the Commission on or prior to the

      deemed to refer to and include the documents incorporated by reference
      therein pursuant to the applicable form under the Act, as of the date of

      supplemented in relation to the Stock in the form in which it is filed
      with the Commission pursuant to Rule 424(b) under the Act, including any
      documents incorporated by reference therein as of the date of such
      filing).  The Company will not file any amendment to the Registration
      Statement or any amendment or supplement to any Preliminary Prospectus or
      Prospectus, or file any document under the Exchange Act before the
      termination of the offering of the Stock by the Underwriters if such
      document would be deemed to be incorporated by reference into such
      Preliminary Prospectus or Prospectus, of which the Representatives shall
      not previously have been advised and provided with a copy or to which the
      Representatives shall reasonably object in writing or which shall be
      disapproved by Messrs. Milbank, Tweed, Hadley & McCloy, who are acting as
      counsel on behalf of the Underwriters.

      make the statements therein not misleading, except that the foregoing
      does not apply to statements or omissions in such documents based upon
      written information furnished to the Company by any Underwriter
      specifically for use therein.  Any reference to "Rules and Regulations"

      Statement or Prospectus as amended or supplemented; such financial
      statements have been prepared in each case in accordance with generally
      accepted accounting principles consistently applied throughout the
      periods involved except as otherwise indicated in the Registration
      Statement and Prospectus as amended and supplemented.  Ernst & Young, who
      have examined the audited financial statements and schedules (including

      the Prospectus as amended or supplemented, are independent public
      accountants as required by the Act and the Rules and Regulations.

           (d)  Except as reflected in, or contemplated by, the Registration
      Statement and the Prospectus as amended or supplemented, since the
      respective most recent dates as of which information is given in the

      properties or financial condition or results of operation of the Company,
      and since such dates there has not been any material transaction entered
      into by the Company other than transactions contemplated by the
      Registration Statement and Prospectus as amended or supplemented and
      transactions in the ordinary course of business.  The Company has no
      material contingent obligation which is not disclosed in the Registration
      Statement and Prospectus as amended or supplemented.

           (e)  The consummation of the transactions herein contemplated and
      the fulfillment of the terms hereof on the part of the Company to be
      fulfilled have been duly authorized by all necessary corporate action of
      the Company in accordance with the provisions of its Restated and Amended
      Certificate of Incorporation (the "Charter") and by-laws and applicable
      law, and the Stock, when issued and delivered as provided herein, will be
      duly issued, fully paid and nonassessable and will have the rights set
      forth in the Charter.  The Stock conforms to the description thereof
      contained in the Registration Statement and the Prospectus as amended or
      supplemented.

           (f)  The issuance and sale of the Stock, the consummation of the
      transactions herein contemplated and the fulfillment of the terms hereof
      will not result in a breach of any of the terms or provisions of, or
      constitute a default under, any indenture, mortgage, deed of trust or
      other agreement or instrument to which the Company is now a party, or the
      Charter.

      the Stock to be issued and the aggregate amount payable on such shares in
      the case of voluntary dissolution shall not exceed said respective
      amounts payable on shares of the preferred stock of the Company which are
      to be purchased, redeemed or otherwise acquired with the proceeds of the
      Stock.] [The net earnings of the Company available for the payment of

      proposed issue of the Stock, for twelve consecutive calendar months
      within the fifteen calendar months immediately preceding the month within
      which the Stock shall be issued.]

           (h)  The documents which are incorporated by reference in the
      Prospectus as amended or supplemented or from which information is so
      incorporated by reference, when they became effective or were filed with
      the Commission, as the case may be, complied in all material respects
      with the requirements of the Act or the Exchange Act, as applicable, and
      the Rules and Regulations, and any documents so filed and incorporated by
      reference subsequent to the effective date of the Registration Statement
      shall, when they are filed with the Commission, conform in all material
      respects to the requirements of the Act or the Exchange Act, as
      applicable, and the Rules and Regulations.

           (i)  The conditions for use of Form S-3, set forth in the General
      Instructions thereto, have been satisfied.

           4.  Purchase and Sale.  On the basis of the representations and
warranties herein contained, but subject to the terms and conditions herein set
forth, the Company agrees to issue and sell to each of the Underwriters, and
each such Underwriter agrees, severally and not jointly, to purchase from the
Company, at the purchase price set forth in Schedule I hereto, the number of
shares of Stock set forth opposite the name of such Underwriter in Schedule II
hereto.

           5.  Reoffering by Underwriters.  Subject to the terms and conditions
of this Agreement, it is understood that the Underwriters propose to make a
bona fide public offering of the Stock as soon as practicable after the
execution of this Agreement.

           6.  Time and Place of Closing.  Delivery of the certificates
representing the Stock (the "Certificates") and payment therefor shall be made
at the offices of Milbank, Tweed, Hadley & McCloy, 1 Chase Manhattan Plaza, New

place, time and date as the Representatives and the Company may agree upon.
The hour and date of such delivery and payment are herein called the "Closing
Date".  Payment for the Stock shall be by certified or official bank check

respective accounts of the Underwriters registered in such names and in such
authorized denominations as the Representatives may
<PAGE>   6
                                                                               6


reasonably request in writing not later than 12:30 P.M., New York Time, on the
third business day prior to the Closing Date, or, to the extent not so
requested, registered in the names of the respective Underwriters in such
authorized denominations as the Company shall determine.  For the purpose of
expediting the checking of the Certificates by the Representatives on behalf of
the Underwriters, the Company agrees to make the Certificates available to the
Representatives for such purposes at the office of The Bank of New York not
later than 2 P.M., New York Time, on the business day preceding the Closing
Date, or at such other time and place as may be agreed upon by the Company and
the Representatives.

           If any Underwriter or Underwriters default in its or their
obligations to purchase the Stock which it or they have agreed to purchase
hereunder and the aggregate number of shares of Stock which such defaulting
Underwriter or Underwriters agreed but failed to purchase is ten percent or
less of the aggregate number of shares of Stock set forth in Schedule II
hereto, the other Underwriters shall be obligated severally, in proportion to
their respective commitments to purchase Stock hereunder, to purchase the Stock
which such defaulting Underwriter or Underwriters agreed but failed to
purchase.  If any Underwriter or Underwriters so default and the aggregate
number of shares of Stock with respect to which such default or defaults occur
is more than ten percent of the aggregate number of shares of Stock set forth
in Schedule II hereto and arrangements satisfactory to you and the Company for
the purchase of such Stock by other persons are not made within thirty-six
hours after such default, the Company may, at its option, either (a) terminate
this Agreement without liability on the part of any non-defaulting Underwriter
or the Company, except for expenses to be paid or reimbursed by the Company
pursuant to Section 7, or (b) require each non-defaulting Underwriter to
purchase the aggregate number of shares of Stock which such Underwriter
otherwise agreed to purchase plus an amount equal to one-ninth thereof.  As
used in this Agreement, the term "Underwriter" includes any person substituted
for an Underwriter under this Section.

           The respective commitments of the several Underwriters for purposes
of this paragraph shall be determined without regard to reduction in the
respective Underwriters' obligations to purchase the number of shares of Stock
set forth opposite their names in Schedule II hereto.  Nothing herein will
relieve a defaulting Underwriter from liability for its default.

           7.  Covenants of the Company.  The Company agrees that:

           (a)  The Company will prepare the Prospectus as amended or
      supplemented in a form approved by the Representatives and will file such
      Prospectus pursuant to Rule 424(b) under the Act not later than the
      Commission's close of business on the second business day following the
      execution and delivery of this Agreement or, if applicable, such earlier
      time as may be required by Rule 424(b).  The Company will at or prior to
      the Closing Date deliver to each of the Representatives and to counsel
      for the Underwriters one signed copy of the Registration Statement as
      originally filed and of all amendments or supplements thereto (including
      conformed copies of any document filed under the Exchange Act and deemed
      to be incorporated by reference into the Prospectus as amended or
      supplemented), heretofore or hereafter made, including any post-effective
      amendment (in each case including all exhibits filed therewith, except
      exhibits incorporated by reference unless specifically requested),
      including a signed copy of each consent and certificate included therein
      or filed as an exhibit thereto.  As soon as the Company is advised
      thereof, it will advise the Representatives orally (i) when any amendment
      to the Registration Statement has been filed or becomes effective or any
      supplement to the Prospectus or any amended Prospectus has been filed
      with the Commission and (ii) of the issuance of any stop order under the
      Act with respect to the Registration Statement or any suspension of the
      qualification of the Stock in any jurisdiction, or the institution of any
      proceedings therefor of which the Company shall have received notice, and
      will use its best efforts to prevent the issuance of any such stop order
      or suspension and to secure the prompt removal thereof if issued.  The
      Company will deliver to the Underwriters, in accordance with the
      Representatives' instructions, as many copies of the Prospectus as
      amended or supplemented as the Representatives may reasonably request for
      the purposes contemplated by the Act, and will deliver to the
      Representatives as soon as practicable sufficient conformed copies of the
      Registration Statement (including conformed copies of any document filed
      under the Exchange Act and deemed to be incorporated by reference into
      the Prospectus as amended or supplemented) and of all amendments thereto
      (in each case without exhibits) for distribution of one to each
      Underwriter.

           (b)  The Company will pay all expenses incident to the performance
      of its obligations under this Agreement and will reimburse the
      Underwriters for any expenses up to $9,000 (including fees and
      disbursements of counsel) incurred by them in connection with
      qualification of the Stock for sale and the preparation of memoranda as
      to Blue Sky qualifications and exemptions and as to eligibility of the
      Stock for investment under the laws of such jurisdictions as
<PAGE>   8
                                                                               8


      you designate.  The Company shall not, however, be required to pay any
      amount for any expenses of the Representatives or any of the Underwriters
      except as provided in paragraph 4 hereof and except, that in the event
      this Agreement shall be terminated in accordance with the provisions of
      paragraph 8 or 9 hereof, the Company will pay the fees and disbursements
      of counsel for the Underwriters, whose fees and disbursements the
      Underwriters agree to pay in any other event.  The Company shall not in
      any event be liable to any of the several Underwriters for damages on
      account of loss of anticipated profits.

           (c)  If at any time when a prospectus relating to the Stock is
      required to be delivered under the Act, any event relating to or
      affecting the Company, or of which the Company shall be advised in
      writing by the Representatives, shall occur, which in the opinion of the
      Company should be set forth in a supplement to or an amendment of the
      Prospectus in order to make the Prospectus as amended or supplemented not
      misleading in the light of the circumstances when it is delivered, or
      which, in your opinion, may be necessary in connection with the
      distribution of the Stock, the Company will forthwith at its expense
      prepare and furnish to the Representatives a reasonable number of copies
      of a supplement or supplements or an amendment or amendments to the
      Prospectus as amended or supplemented which will supplement or amend the
      Prospectus as amended or supplemented or file such documents so that the
      Prospectus as amended or supplemented will not contain any untrue
      statement of a material fact or omit to state any material fact necessary
      in order to make the statements therein, in the light of the
      circumstances when the Prospectus as amended or supplemented is
      delivered, not misleading.  The Company will continue to prepare and file
      with the Commission in a timely manner all documents required to be filed
      pursuant to the requirements of the Exchange Act and the Rules and
      Regulations.

           (d)  The Company will make generally available to its security
      holders (and shall deliver to the Representatives), as soon as
      practicable but in any event not later than 45 days after the end of its
      fiscal quarter in which the first anniversary date of the effective date
      of the Registration Statement (as such term is defined in Rule 158 under
      the Act) (the "Effective Date") occurs, an earnings statement (which need
      not be audited, unless required so to be under Section 11(a) of the Act)
      of the Company in reasonable detail covering a period of at least twelve
      consecutive months beginning after the Effective Date.

           (e)  The Company will use its best efforts promptly to do and
      perform all things to be done and performed by it
<PAGE>   9
                                                                               9


      hereunder prior to the Closing Date and to satisfy all conditions
      precedent to the delivery by it of the Stock.

           (f)  The Company will use its best efforts to qualify the Stock for
      offer and sale under the Blue Sky laws of such states as the
      Representatives may designate and will file such statements or reports as
      are or may be reasonably required by the laws of such states; provided,
      however, that the Company in complying with this paragraph need not
      qualify to do business in any state nor execute a general consent to
      service of process.

           (g)  The Company will apply the proceeds of the sale of the Stock
      for the purposes set forth in the Prospectus as amended or supplemented.

           8.  Conditions of Underwriters' Obligations.  The several
obligations of the Underwriters to purchase and pay for the Stock shall be
subject to the accuracy of, and compliance with, the representations and
warranties of the Company contained herein, to the performance by the Company
of its obligations to be performed hereunder prior to the Closing Date, and to
the following further conditions:

           (a)  The Prospectus as amended or supplemented in relation to the
      Stock shall have been filed with the Commission pursuant to Rule 424(b)
      within the applicable time period prescribed for such filing by the Rules
      and Regulations; and no stop order suspending the effectiveness of the
      Registration Statement shall be in effect on the Closing Date and no
      proceedings for that purpose shall be pending before, or threatened by,
      the Commission on the Closing Date.  The Representatives shall have
      received, prior to payment for the Stock, a certificate dated the Closing
      Date and signed by the President, any Vice President or the Treasurer of
      the Company to the effect that no such stop order is in effect and that
      no proceedings for such purpose are pending before, or to the knowledge
      of the Company threatened by, the Commission.

           (b)  On the Closing Date there shall be in full force and effect an
      order of the Public Service Commission of the State of New York
      authorizing the issuance and sale of the Stock which shall not contain
      any provision mutually unacceptable to the Representatives and the
      Company by reason of being materially adverse, it being understood that
      no order in effect at the date of this Agreement contains any such
      unacceptable provision.

           (c)  At the Closing Date, the Representatives shall receive a
      favorable opinion from either Robert J. Grey, Esq., General Counsel of
      the Company, or Herbert M. Leiman, Esq., Assistant General Counsel of the
      Company, which
<PAGE>   10
                                                                              10


      opinion shall be satisfactory in form and substance to Messrs. Milbank,
      Tweed, Hadley & McCloy, counsel for the Underwriters, to the effect 
      that --

                (i)  The Company is a corporation duly organized and validly
           existing, in good standing under the laws of the State of New York,
           with power and authority (corporate and other) to own its property,
           to carry on its business and to issue the Stock;

               (ii)  The Agreement has been duly authorized, executed and 
           delivered by the Company;

              (iii)  The Stock has been duly authorized and issued, is fully
           paid and nonassessable and conforms to the description thereof
           contained in the Registration Statement and the Prospectus as
           amended or supplemented;

               (iv)  An order has been adopted by the Public Service Commission
           of the State of New York authorizing the issuance and sale of the
           Stock and the transactions related thereto as contemplated by the
           Agreement and said order is still in full force and effect; and no
           further approval, authorization, consent or other order of any
           public board or body is legally required for the authorization of
           the issuance and sale by the Company of the Stock under the terms of
           this Agreement except compliance with the provisions of securities
           or Blue Sky laws of certain states in connection with the sale of
           the Stock to the public in such states;

                (v)  The execution, delivery and performance of this Agreement
           and the Stock by the Company and the consummation by the Company of
           the transactions contemplated hereby will not conflict with or
           result in a breach or violation by the Company of any of the terms
           or provisions of, constitute a default by the Company under, or
           result in the creation or imposition of any lien, charge, security
           interest or encumbrance upon any of the assets of the Company
           pursuant to the terms of, (A) any indenture, mortgage, deed of
           trust, loan agreement, lease or other agreement or instrument known
           to such counsel to which the Company is a party or to which it or
           any of its properties is subject, (B) the Restated and Amended
           Certificate of Incorporation or By-laws of the Company or (C) any
           statute, rule or regulation or, to the best of such counsel's
           knowledge, any judgment, decree or order of any court or
           governmental agency or body applicable to the Company or any of its
           properties;
<PAGE>   11
                                                                              11


               (vi)  The Company, to the best of such counsel's knowledge,
           possesses all franchises, licenses, permits, consents and orders of
           governmental and regulatory authorities and political subdivisions
           required for the maintenance and operation of its properties and
           business substantially as now conducted and as described in the
           Registration Statement and the Prospectus as amended or
           supplemented; or, if the Company does not possess all of such
           franchises, licenses, permits, consents and orders, the absence of
           such thereof as the Company does not possess will not, to the best
           of such counsel's knowledge, affect the maintenance and operation of
           such properties and business as a whole substantially as now
           conducted; and

              (vii)  The Registration Statement has become effective under the
           Act and, to the best knowledge of such counsel, no stop order
           suspending the effectiveness of the Registration Statement has been
           issued and no proceedings for that purpose have been instituted or
           are pending or contemplated under the Act, the Registration
           Statement and the Prospectus, and each amendment or supplement
           thereto (including any document incorporated by reference into the
           Prospectus as amended or supplemented), as of their respective
           effective or issue dates, complied as to form in all material
           respects with the requirements of the Act and the Exchange Act and
           the Rules and Regulations; the conditions for use of Form S-3, set
           forth in the General Instructions thereto, have been satisfied; such
           counsel has no reason to believe that either the Registration
           Statement or the Prospectus, or any such amendment or supplement
           (including any document filed under the Exchange Act and deemed to
           be incorporated by reference into the Prospectus as amended or
           supplemented), considered as a whole on the effective date of the
           Registration Statement and on the date hereof contained or contain
           any untrue statement of material fact or omitted or omit to state
           any material fact required to be stated therein or necessary to make
           the statements therein not misleading; the descriptions in the
           Registration Statement and the Prospectus as amended or supplemented
           of statutes, legal and governmental proceedings and contracts and
           other documents are accurate and fairly present the information
           required to be shown; and such counsel does not know of any legal or
           governmental proceedings required to be described in the Prospectus
           as amended or supplemented (or required to be filed under the
           Exchange Act if upon such filing they would be incorporated, in
           whole or in part, by reference in the Prospectus as amended or
           supplemented) which are not described as required, nor of any
           contracts or

           documents of a character required to be described in the
           Registration Statement or Prospectus as amended or supplemented or
           to be filed as exhibits to the Registration Statement which are not
           described and filed as required; it being understood that such
           counsel need express no opinion as to the financial statements or
           other financial data contained or incorporated by reference in the
           Registration Statement or the Prospectus as amended or supplemented.

           (d)  At the Closing Date, the Representatives shall receive from
      Messrs. Milbank, Tweed, Hadley & McCloy, counsel for the Underwriters,
      such opinion or opinions with respect to the valid existence of the
      Company, the validity of the Stock, the Registration Statement, the
      Prospectus as amended or supplemented, and other related matters as the
      Representatives may require, and the Company shall have furnished to such
      counsel such documents as they request for the purpose of enabling them
      to pass upon such matters.

           (e)  On the date of this Agreement and on the Closing Date the
      Representatives shall have received from Ernst & Young a letter (with
      copies thereof for each of the Underwriters), which letter shall be
      reasonably satisfactory in form and substance to the Representatives and
      Messrs. Milbank, Tweed, Hadley & McCloy, counsel for the Underwriters,
      confirming that they are independent auditors with respect to the Company
      within the meaning of the Act and the applicable published rules and
      regulations thereunder, and stating in effect that:

                (i)  in their opinion, the audited financial statements and
           schedules incorporated by reference into the Registration Statement
           and the Prospectus as amended or supplemented audited by them comply
           as to form in all material respects with the applicable accounting
           requirements of the Act or the Exchange Act, as applicable, and the
           applicable published rules and regulations of the Commission
           thereunder with respect to a registration statement on Form S-3;

                (ii)  they have read the minutes of the meetings of the
           stockholders and the Board of Directors of the Company, as set forth
           in the minute books or, if not set forth therein, in the form
           prepared by the Secretary of the Company, through a specified date
           not more than five business days prior to the date of the closing,
           read the unaudited financial statements, if any, incorporated by
           reference into the Registration Statement and Prospectus as amended
           or supplemented and also the latest available unaudited interim
           financial statements of the Company and inquired of certain
           officials of the Company responsible for financial and

                                                                              13


           accounting matters, and that such officials have stated that:

                    (A)  any unaudited Balance Sheet, Statement of Income and
                Statement of Cash Flows included or incorporated by reference
                in the Registration Statement and Prospectus as amended or
                supplemented complies as to form in all material respects with
                the applicable accounting requirements of the Act and the
                Exchange Act and the published rules and regulations of the
                Commission thereunder, and are in conformity with generally
                accepted accounting principles applied on a basis substantially
                consistent with that of the most recent audited financial
                statements incorporated by reference therein,

                    (B)  at the date of the latest available balance sheet read
                by such accountants, there was no change in the capital stock
                (including Common Stock, Preferred Stock and Premium on Capital
                Stock but excluding Capital Stock Expense) or long-term debt of
                the Company or any decrease in net current assets or Common
                Shareowners' Equity as compared with amounts shown on the
                latest balance sheet included or incorporated by reference in
                the Registration Statement and Prospectus as amended or
                supplemented, except in all instances (i) for changes or
                decreases that the Registration Statement and Prospectus as
                amended or supplemented discloses have occurred or may occur,
                (ii) for payment of maturing installments of long-term debt,
                (iii) for conversions of convertible preferred stock, (iv) for
                shares of common stock issued pursuant to the Company's
                Employee Stock Purchase Plan, (v) for amounts withheld from
                employees in connection with the Employee Stock Purchase Plan,

                purposes, (vii) for shares of preferred stock redeemed by way
                of sinking funds, or (viii) for changes or decreases which are
                described in such letter, identifying the same and specifying
                the amount thereof, or

                decreases which the Registration Statement and Prospectus as
                amended or supplemented discloses have occurred or may occur,
                or which are described in such letter, identifying the same and
                specifying the amount thereof;

                (iii)  they have performed more limited procedures than those
           set forth in the foregoing clause (ii), consisting merely of the
           reading of the minutes referred to in said clause and inquired of
           certain officials of the Company responsible for financial and
           accounting matters, and that such officials have stated that, with
           respect to the period from the date of the latest available
           financial statements of the Company to a specified date not more
           than five business days prior to the date of such letter, there was

           Stock and Premium on Capital Stock but excluding Capital Stock
           Expense) or long-term debt of the Company or any decrease in net
           current assets or Common Shareowners' Equity as compared with the
           amounts shown in the latest balance sheet included or incorporated
           by reference in the Registration Statement and Prospectus as amended
           or supplemented, except in all instances (i) for changes or

           or supplemented discloses have occurred or may occur, (ii) for
           payment of maturing installments of long-term debt, (iii) for
           conversions of convertible preferred stock, (iv) for shares of
           common stock issued pursuant to the Company's Employee Stock

           described in such letter, identifying the same and specifying the
           amount thereof; and

                (iv)  they have compared certain dollar amounts (and
           percentages and other financial data derived from such dollar
           amounts) disclosed in, or incorporated by reference into, the

           in Exhibits to the Registration Statement, with such dollar amounts,
           percentages and other financial information contained in the general
           accounting records of the Company or derived directly from such
           records by analysis or computation, and have found such dollar

           (f)  Since the respective most recent dates as of which information
      is given in the Registration Statement and Prospectus as amended or
      supplemented and up to the Closing Date, there shall have been no
      material adverse change in the business, properties or financial
      condition or results of operation of the Company, except as reflected in
      or contemplated by the Registration Statement and the Prospectus, and any
      amendments or supplements thereto (including any documents filed under
      the Exchange Act and deemed to be incorporated by reference into the
      Prospectus as amended or supplemented), and since such dates and up to
      the Closing Date there shall have been no material transaction entered
      into by the Company other than transactions disclosed by the Registration
      Statement and the Prospectus, and any amendments or supplements thereto
      (including any documents filed under the Exchange Act and deemed to be
      incorporated by reference into the Prospectus as amended or
      supplemented), and transactions in the ordinary course of business; and
      at the Closing Date the Representatives shall have received a certificate
      to such effect, signed by the President, any Vice President or the
      Treasurer of the Company.

           (g)  All legal proceedings to be taken in connection with the
      issuance and sale of the Stock shall have been satisfactory in form and
      substance to Messrs. Milbank, Tweed, Hadley & McCloy.

           In case any of the conditions specified above in this Section 8
shall not have been fulfilled at the Closing Date, this Agreement may be
terminated by the Representatives, by mailing or delivering written notice
thereof to the Company.  Any such termination shall be without liability of any
party to any other party except as otherwise provided in Section 7 hereof.

           9.  Conditions of the Obligation of the Company.  The obligation of
the Company to deliver the Stock shall be subject to the conditions set forth
in the second clause of the first sentence of paragraph (a) of Section 8 hereof
and in paragraph (b) of Section 8 hereof.  In case any of the conditions
specified in this Section 9 shall not have been fulfilled, this Agreement may
be terminated by the Company by mailing or delivering written notice thereof to
the Representatives.  Any such termination shall be without liability of any
party to any other party except as otherwise provided in Section 7 hereof.

           10.  Indemnification.  (a)  The Company agrees to indemnify and hold
harmless each Underwriter and each person who controls any Underwriter within
the meaning of Section 15 of the Act against any and all losses, claims,
damages or liabilities, joint or several, to which they or any of them may
become subject under the Act or any other statute or common law and to
reimburse, as incurred, each such Underwriter and controlling

                                                                              16


person for any legal or other expense (including, to the extent hereinafter
provided, reasonable counsel fees) incurred by them in connection with
investigating any such losses, claims, damages or liabilities or in connection
with preparing to defend or defending any actions, insofar as such losses,
claims, damages, liabilities, expenses or actions arise out of or are based
upon any untrue statement or alleged untrue statement of a material fact
contained in any Preliminary Prospectus, any preliminary prospectus supplement,
the Registration Statement, the Prospectus as amended or supplemented or any
amendment or supplement thereto (if any amendments or supplements thereto shall
have been furnished) or the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading; PROVIDED, HOWEVER, that the indemnity agreement
contained in this paragraph shall not apply to any such losses, claims,
damages, liabilities, expenses or actions arising out of or based upon any such
untrue statement or alleged untrue statement or any such omission or alleged
omission, if such statement or omission was made in reliance upon information
furnished herein or in writing to the Company by or on behalf of any
Underwriter, through the Representatives, expressly for use in any Preliminary
Prospectus, any preliminary prospectus supplement, the Registration Statement,
the Prospectus as amended or supplemented or any amendment or supplement
thereto; and PROVIDED, FURTHER, that the Company shall not be liable in any
case relating to any Preliminary Prospectus or any preliminary prospectus
supplement to the extent that any such loss, claim, damage, liability, expense
or action arises out of or is based upon the failure of any Underwriter in
connection with a sale of any of the Stock to any person to send or give a copy
of the Prospectus, as the same may then be supplemented or amended, to such
person with or prior to the written confirmation of the sale involved so long
as the Company shall have fully complied with the last sentence of Section 7(a)
hereof.  The indemnity agreement of the Company contained in this paragraph and
the representations and warranties of the Company contained in Section 3 hereof
shall remain operative and in full force and effect, regardless of any
investigation made by or on behalf of any Underwriter or any such controlling
person, and shall survive the delivery of the Stock.  The Underwriters agree
promptly to notify the Company of the commencement of any litigation or
proceedings against them or any of them, or any such controlling person, in
connection with the sale of the Stock or with any Preliminary Prospectus, any
preliminary prospectus supplement, the Registration Statement, the Prospectus
as amended or supplemented or any amendment or supplement thereto.

           (b)  Each Underwriter agrees to indemnify and hold harmless the
Company, its officers and directors, each other Underwriter, and each person
who controls any thereof within the meaning of Section 15 of the Act, against
any and all losses, claims, damages or liabilities, joint or several, to which
they or any of them become subject under the Act or any other statute

                                                                              17


or common law and to reimburse each of them for any legal or other expenses
(including, to the extent hereinafter provided, reasonable counsel fees)
incurred by them in connection with investigating any such losses, claims,
damages or liabilities or in connection with defending any actions, insofar as
such losses, claims, damages, liabilities, expenses or actions arise out of or
are based upon any untrue statement or alleged untrue statement of a material
fact contained in any Preliminary Prospectus, any preliminary prospectus
supplement, the Registration Statement, the Prospectus as amended or
supplemented or any amendment or supplement thereto (if any amendments or
supplements thereto shall have been furnished) or the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, if such statement or
omission was made in reliance upon information furnished herein or in writing
to the Company by or on behalf of such Underwriter, through the
Representatives, expressly for use in any Preliminary Prospectus, any
preliminary prospectus supplement, the Registration Statement, the Prospectus
as amended or supplemented or any amendment or supplement thereto.  The
indemnity agreement of the respective Underwriters contained in this paragraph
shall remain operative and in full force and effect, regardless of any
investigation made by or on behalf of the Company, or any such other
Underwriter or any such controlling person, and shall survive the delivery of
the Stock.  The Company agrees promptly to notify the Representatives of the
commencement of any litigation or proceedings against the Company or any of its
officers or directors or against any such controlling person in connection with
the sale of the Stock or with any Preliminary Prospectus, any preliminary
prospectus supplement, the Registration Statement, the Prospectus as amended or
supplemented or any amendment or supplement thereto.

           (c)  The Company and each of the Underwriters agree that, upon
receipt of notice of the commencement of any action against the Company or any
person controlling the Company, or against such Underwriter or any person
controlling such Underwriter, in respect of which indemnity may be sought on
account of any indemnity agreement contained herein, it will promptly give
written notice of the commencement thereof to the party or parties against whom
indemnity shall be sought hereunder, but the omission so to notify such
indemnifying party or parties of any such action shall not relieve such
indemnifying party or parties from any liability which it or they may have to
the indemnified party (i) to the extent the indemnifying party was not
materially prejudiced by such omission or (ii) otherwise than on account of
such indemnity agreement.  In case such notice of any such action shall be so
given such indemnifying party shall be entitled to participate at its own
expense in the defense or, if it so elects, to assume (in conjunction with any
other indemnifying parties) the defense of such action, in which event such
defense shall be conducted by counsel chosen by such indemnifying party (or
parties) and satisfactory to the
<PAGE>   18
                                                                              18


indemnified party or parties who shall be defendant or defendants in such
action; provided, however, if the defendants in any such action include both
the indemnified party and the indemnifying party and the indemnified party
shall have reasonably concluded that there may be legal defenses available to
it and/or other indemnified parties which are different from or additional to
those available to the indemnifying party, the indemnified party or parties
shall have the right to select separate counsel to assume such legal defenses
and to otherwise participate in the defense of such action on behalf of such
indemnified party or parties.  Upon receipt of notice from the indemnifying
party to such indemnified party of its election so to assume the defense of
such action and approval by the indemnified party of counsel, the indemnifying
party will not be liable to such indemnified party under this Section 10 for
any legal or other expenses subsequently incurred by such indemnified party in
connection with the defense thereof other than reasonable costs of
investigation unless (i) the indemnified party shall have employed such counsel
in connection with the assumption of legal defenses in accordance with the
proviso to the next preceding sentence (it being understood, however, that the
indemnifying party shall not be liable for the expenses of more than one
separate counsel, approved by the Representatives in the case of paragraph (a)
of this Section 10, representing the indemnified parties under paragraph (a) or
(b) of this Section 10, as the case may be, who are parties to such action),
(ii) the indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of commencement of the action or (iii) the indemnifying party has
authorized the employment of counsel for the indemnified party at the expense
of the indemnifying party.

           (d)  If the indemnification provided for in this Section 10 shall
for any reason be unavailable to an indemnified party under paragraphs (a) or
(b) of this Section 10 in respect of any loss, claim, damage or liability, or
any action in respect thereof, referred to therein, then each indemnifying
party shall, in lieu of indemnifying such indemnified party, contribute to the
amount paid or payable by such indemnified party as a result of such loss,
claim, damage or liability, or action in respect thereof, (i) in such
proportion as shall be appropriate to reflect the relative benefits received by
the Company on the one hand and the Underwriters on the other from the offering
of the Stock or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause (i) above but also the
relative fault of the Company on the one hand and the Underwriters on the other
with respect to the statements or omissions which resulted in such loss, claim,
damage or liability, or action in respect thereof, as well as any other
relevant equitable considerations.  The relative benefits received by the
Company on the one hand and the Underwriters on
<PAGE>   19
                                                                              19


the other with respect to such offering shall be deemed to be in the same
proportion as the total net proceeds from the offering of the Stock (before
deducting expenses) received by the Company bear to the total underwriting
discounts and commissions received by the Underwriters with respect to such
offering, in each case as set forth in the table on the cover page of the
Prospectus.  The relative fault shall be determined by reference to whether the
untrue or alleged untrue statement of a material fact or omission or alleged
omission to state a material fact relates to information supplied by the
Company or the Underwriters, the intent of the parties and their relative
knowledge, access to information and opportunity to correct or prevent such
statement or omission.  The Company and the Underwriters agree that it would
not be just and equitable if contributions pursuant to this Section 10 were to
be determined by pro rata allocation or by any other method of allocation which
does not take into account the equitable considerations referred to herein.
The amount paid or payable by an indemnified party as a result of the loss,
claim, damage or liability, or action in respect thereof, referred to above in
this Section 10 shall be deemed to include, for purposes of this Section 10,
any legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 10, no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Stock underwritten by it and distributed to the public were
offered to the public exceeds the amount of any damages which such Underwriter
has otherwise paid or becomes liable to pay by reason of any untrue or alleged
untrue statement or omission or alleged omission.  No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.  The Underwriters' obligations to contribute as
provided in this paragraph (d) are several in proportion to their respective
underwriting obligations and not joint.

           (e)  The agreements contained in this Section 10, the
representations and warranties of the Company in Section 3 hereof and the
agreements of the Company in Section 7 hereof shall survive the delivery of the
Stock.  The agreements contained in this Section 10, the representations and
warranties of the Company in Section 3 hereof and the agreements of the Company
in Section 7(b) hereof shall remain in full force and effect, regardless of any
termination or cancellation of this Agreement or any investigation made by or
on behalf of any indemnified party.

           11.  Termination.  This Agreement may be terminated at any time
prior to the Closing Date by the Representatives with the consent of a majority
in interest of the Underwriters including yourselves upon notice thereof to the
Company, if prior to such time (a) the Company has failed, refused or been
unable
<PAGE>   20
                                                                              20


to perform any agreement on its part to be performed hereunder, (b) any other
condition of the Underwriters' obligations hereunder is not fulfilled, (c)
there shall have occurred any general suspension of trading in securities on
the New York Stock Exchange or the American Stock Exchange or there shall have
been established by the New York Stock Exchange or the American Stock Exchange
or by the Commission or by any federal or state agency or by the decision of
any court any limitation on prices for such trading or any restrictions on the
distribution of securities, (d) a banking moratorium shall have been declared
either by federal or New York State authorities, (e) an outbreak or escalation
of hostilities involving the United States shall have occurred or there shall
have been a declaration by the United States of a national emergency or war or
(f) there shall have occurred such a material adverse change in general
economic, political or financial conditions, or the effect of international
conditions on the financial markets in the United States is such, as to make it
impracticable or inadvisable, in the judgment of a majority in interest of the
Underwriters, to proceed with the delivery of the Stock.  Any termination
hereof pursuant to this Section 11 shall be without liability of any party to
any other party except as otherwise provided in Section 7 hereof.

           12.  Information Furnished by Underwriters.  The statements set
forth in the last paragraph on the cover page, the paragraph containing
stabilization information on the inside front cover page and the statements
under the caption "Underwriting" in any Prospectus as amended or supplemented
constitute the only written information furnished by or on behalf of any

required to consent to any such supplemental indenture, without the consent of
the holders of all General and Refunding Bonds then outstanding, or (iii)

effectively revoked as provided in the General and Refunding Indenture) shall
be conclusive and binding upon such holder and upon all future holders of this
General and Refunding Bond, or General and Refunding Bonds issued in exchange

Series     and (to the extent that payment of such interest is enforceable
under applicable law) on overdue instalments of interest of Bonds of Series
at the rate of six per centum (6%) per annum. Both the principal of and
interest on the Bonds of Series     shall be paid at the office or agency of
the Company in the Borough of Manhattan in The City of New York, in any coin or
currency of the United States of America which at the time of payment shall be
legal tender for public and private debts.

         SECTION 2.  The provisions of the second paragraph of Section 2.05 of
the Indenture shall not be applicable to the Bonds of Series . All Bonds of
Series     shall be dated the date of their authentication, and shall bear
interest from the date specified in such Bond as below provided as the
commencement of the first interest period, or from the most recent interest
date to which interest has been paid or duly provided for. Interest on any Bond
of Series     which is payable, and is punctually paid or duly provided for, on
any interest date shall be paid to the person in whose name that Bond (or one
or more Bonds of Series     evidencing all or a portion of the same debt) is
registered at the close of business on the Regular Record Date for such
interest which shall be the       day of         or     , as the case may be,
next preceding such interest date whether or not such       day of         or
is a day which is not a day on which banking institutions in The City of New
York are authorized or required by law or executive order to be closed
(hereinafter a "Business Day").

         SECTION 3.  Any interest on any Bond of Series     which is payable,
but is not punctually paid or duly provided for, on any interest date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the
registered holder on the relevant Regular Record Date by virtue of having been
such holder; and such Defaulted Interest may be paid by the Company, at its
election in each case, as provided in Clause (1) or Clause (2) below:

                 (1)      The Company may elect to make payment of any
         Defaulted Interest to the persons in whose names the Bonds of Series
         (or the respective Bonds of Series     evidencing all or a portion of
         the same debt) are registered at the close of business on a Special
         Record Date for the payment of such Defaulted Interest, which shall be
         fixed in the following manner. The Company shall notify the Trustee in
         writing of the amount of Defaulted Interest proposed to be paid on
         each Bond of Series     and the date of the proposed payment, and at
         the same time the Company shall make arrangements satisfactory to the
         Trustee for the deposit with the Trustee of an amount of money equal
         to the aggregate amount proposed to be paid in respect of such
         Defaulted Interest prior to the date of the proposed payment, such
         money when deposited to be held in trust for the benefit of the
         persons entitled to such Defaulted Interest as in this Clause
         provided. Thereupon the Trustee shall fix a Special Record Date for
         the payment of such Defaulted Interest
<PAGE>   34
                                       33

         which shall be not more than 15 nor less than 5 days prior to the date
         of the proposed payment and not less than 10 days after the receipt by
         the Trustee of the notice of the proposed payment. The Trustee shall
         promptly notify the Company of such Special Record Date and, in the
         name and at the expense of the Company, shall cause notice of the
         proposed payment of such Defaulted Interest and the Special Record
         Date therefor to be mailed, first class postage prepaid, to each
         holder of a Bond of Series     at his address as it appears in the
         Bond register, not less than 10 days prior to such Special Record
         Date. The Trustee may, in its discretion, in the name and at the
         expense of the Company, cause a similar notice to be published at
         least once in a daily newspaper in the Borough of Manhattan in The
         City of New York, but such publication shall not be a condition
         precedent to the establishment of such Special Record Date. Notice of
         the proposed payment of such Defaulted Interest and the Special Record
         Date therefor having been mailed as aforesaid, such Defaulted Interest
         shall be paid to the persons in whose names the Bonds of Series
         (or the respective Bonds of Series evidencing all or a portion of the
         same debt) are registered on such Special Record Date and shall no
         longer be payable pursuant to the following Clause (2).

                 (2)      The Company may make payment of any Defaulted
         Interest in any other lawful manner not inconsistent with the
         requirements of any securities exchange on which the Bonds of Series
         may be listed, and upon such notice as may be required by such
         exchange, if after notice given by the Company to the Trustee of the
         proposed payment pursuant to this Clause, such payment shall be deemed
         practicable by the Trustee.

         SECTION 4.  The Bonds of Series     shall be redeemable at a
redemption price of one hundred per centum (100%) of their principal amount,
together with accrued interest thereon from the interest date to which interest
has previously been paid or made available for payment to the date fixed for
redemption, upon the application of Trust Moneys pursuant to the last paragraph
of Section 9.04, and Sections 9.10 and 9.11 of the Indenture.

         Bonds of Series     shall be redeemed in accordance with their terms
and Article Eleven of the Indenture.

         SECTION 5.  In order to prevent the application of the provisions of
Section 9.10 of the Indenture requiring the redemption of Bonds pursuant to
said Section, the Company shall use its best efforts to take such action as may
be necessary so that at no time shall there have been on deposit at all times
during the preceding three years Trust Moneys in an amount in excess of
$25,000.
<PAGE>   35
                                       34

         The Company shall, in the manner provided in Sections 9.04A and 12.01
of the Indenture, use its best efforts to make alternative directions and
designations so that it shall not be required by the provisions of said
Sections to purchase or redeem any Bonds of Series    .


         SECTION 6.  No payment by way of principal or interest on any Bond of
Series     shall be made if the Trustee shall have received written notice
signed on behalf of the registered holder of such Bond of Series     stating
that the same has been waived by such registered holder and such waiver shall
not have been revoked, all in the manner and at the times hereinafter
specified. With respect to principal of any Bond of Series     becoming due and
payable on any date, said notice shall be on file with the Trustee at the close
of business on said due date if said due date is a Business Day, or, if said
due date is not a Business Day, then on the Business Day next following said
due date.  With respect to any instalment of interest on any Bond of Series
, said notice shall be on file with the Trustee at the close of business on the
date which is the 30th day after the date fixed for payment of such instalment
or, if said 30th day is not a Business Day, on the Business Day  next preceding
said 30th day. The above-mentioned notices of waiver may be revoked by written
notice signed and filed with the Trustee in the same manner specified herein
for a notice of waiver.

         Unless a waiver is so revoked, (a) at the close of business on the
date when any principal of any Bond of Series     with respect to which a
waiver was on file with the Trustee as aforesaid shall become due and payable
or, if said due date is not a Business Day, on the Business Day next following
said due date, such principal shall cease to be payable, and interest shall
thereupon cease to accrue thereon, and (b) at the close of business on the date
which is the 30th day after the date fixed for payment of any instalment of
interest with respect to which a waiver was on file with the Trustee as
aforesaid or, if said 30th day is not a Business Day, on the Business Day next
preceding said 30th day, such instalment shall cease to be payable.

         Said notice shall specify the certificate numbers and denominations of
Bonds of Series     to which it applies and the principal or instalments of
interest being thereby waived and shall state that the person signing or on
whose behalf it is signed is the registered holder of said Bonds of Series    ,
that said Bonds of Series     are in said registered holder's possession and,
if required by the Trustee, will be promptly produced for inspection by the
Trustee, that payment of the principal of or instalments of interest specified
therein are thereby waived, that said notice is being delivered to the Trustee
for the purpose of being relied on by the Trustee in the administration of the
trust under the Indenture, that the Trustee may so rely and that the person(s)
signing are thereunto duly authorized.
<PAGE>   36
                                       35

         Where the person on whose behalf a notice is given is a corporation,
said notice shall be signed by the President or any Vice President, Cashier,
Controller, Treasurer, Trust Officer or Assistant Vice President, and by an
Assistant Cashier, Assistant Controller, Assistant Treasurer or Assistant Trust
Officer.

         The Trustee shall be entitled to rely upon and shall be fully
protected in relying upon written notices delivered to it in accordance with
this Section 6.

         SECTION 7.  The Company covenants that the annual interest charges on
the Bonds of Series     which would be payable except for the waiver of such
payment described in Section 6 hereof shall be included as annual interest
charges upon the Company's Secured Debt (as defined in the Indenture) for the
purpose of any Gross Income Certificate under the Indenture.

         SECTION 8.  All Bonds of Series     shall, upon surrender to the
Trustee at its corporate trust office, be exchangeable for other Bonds of
Series      of a different authorized denomination or denominations, as
requested by the holder surrendering the same, but of a like aggregate
principal amount. The Company will execute and the Trustee shall authenticate
and deliver registered Bonds of Series     whenever the same shall be required
for any such exchange.

         For any exchange of Bonds of Series     (other than exchanges
expressly provided in the Indenture to be made at the Company's own expense or
without expense or without charge to Bondholders) or for any transfer of any
Bond of Series    , the Company, at its option, may require the payment by the
Bondholder of a sum sufficient to reimburse it for any stamp tax and/or any
other governmental charge incident thereto, but, notwithstanding the provisions
of the last paragraph of Section 2.08 of the Indenture, no other charge shall
be made by the Company for any such exchange or transfer.

         The right reserved by the Company in the first paragraph of Section
2.06 of the Indenture not to make any transfers or exchanges of Bonds for a
period of 10 days next preceding any interest payment date shall not be
applicable to transfers or exchanges of Bonds of Series .

         Except as hereinabove provided in this Section, exchanges of Bonds of
Series     shall be subject to Sections 2.06 and 2.08 of the Indenture.

         The Trustee is hereby appointed Registrar of the Bonds of Series
for the purpose of registering and transferring Bonds of Series     as provided
in the Indenture.

                                  (Continued)

         The interest so payable, and punctually paid or duly provided for, on
any interest date will, as provided in the Indenture hereinafter mentioned, be
paid to the person in whose name this Bond (or any Bond or Bonds evidencing all
or a portion of the same debt) is registered at the close of business on the

Record Date, and may be paid to the person in whose name this Bond (or any Bond
or Bonds evidencing all or a portion of the same debt) is registered at the
close of business on a Special Record Date for the payment of such defaulted
interest to be fixed by the Trustee, notice whereof shall be given to the
registered holder hereof not less than 10 days prior to such Special Record
Date, or may be paid at any time in any other lawful manner not inconsistent
with the requirements of any securities exchange on which this Bond may be
listed, and upon such notice as may be required by such exchange, all as more
fully provided for in the Indenture hereinafter mentioned.

         If an Event of Default, as defined in the Indenture hereinafter
mentioned, shall occur, the principal of this Bond may become or be declared
due and payable, in the manner and with the effect provided in the Indenture
hereinafter mentioned.

         This Bond is one of an authorized issue of Bonds of the Company known
as its "First Mortgage Bonds", not limited in principal amount except as in the
Indenture hereinafter mentioned provided, issued and to be issued in one or
more series under, and all equally and ratably secured (except as any sinking
or other fund may afford additional special security for the Bonds of any
particular series) by, an Indenture of Mortgage and Deed of Trust dated as of
September 1, 1951, executed by the Company to City Bank Farmers Trust Company
(subsequently converted into First National City Trust Company, which was
merged into First National City Bank, now named Citibank, N.A.), as Trustee
(hereinafter referred to as "the Trustee" which term includes any successor
trustee) (herein, together
<PAGE>   41
                                       40

with all indentures supplemental thereto, called "the Indenture") to which
Indenture reference is hereby made for a description of the properties thereby
mortgaged and conveyed, the nature and extent of the security, the rights of
the holders of said Bonds and of the Trustee and of the Company in respect of
such security, and the terms upon which said Bonds are and are to be
authenticated and delivered.
         As provided in the Indenture, said Bonds are issuable in series which
may vary as to maturity, interest and otherwise as in the Indenture provided or
permitted. This Bond is one of a series entitled "First Mortgage Bonds, Series
% Due     " created by a Supplemental Indenture dated as of       ,      as
provided for in the Indenture.

         As provided in, and to the extent permitted by, the Indenture, the
rights and obligations of the Company and of the holders of said Bonds may be
modified by the Company with the consent of the holders of not less than
seventy-five per centum (75%) in principal amount of all the Bonds of all
series then outstanding which are affected by such modification (excluding
Bonds disqualified from voting by reason of the Company's interest therein as
provided in the Indenture). The Indenture provides, among other things, that,
without the consent of the holder hereof, no such modification shall effect the
reduction, or the extension of the stated time of payment, of the principal
hereof, or of the interest hereon, or permit the creation of any lien on the
properties so mortgaged and conveyed prior to or on a parity with the lien of
the Indenture (except as therein expressly permitted) or deprive the holder
hereof of the lien created by the Indenture on said properties. The holders of
not less than sixty-six and two-thirds per centum (662/3%) in principal amount
of all Bonds of all series then outstanding (excluding Bonds disqualified as
aforesaid) may on behalf of the holders of all such Bonds waive any past
default under the Indenture and its consequences, except a default in the
payment of the principal of, or premium or interest on, any of the Bonds as and
when the same shall become due by the terms of such Bonds or a call for
redemption.

         No recourse shall be had for the payment of the principal of or the
interest or premium on this Bond, or for any claim based hereon or otherwise in
respect hereof or of the Indenture, against any incorporator, stockholder,
director or officer, as such, past, present or future, of the Company or of any
predecessor or successor corporation, either directly or through the Company or
any predecessor or successor corporation, whether by virtue of any
constitution, statute or rule of law, or by the enforcement of any assessment
or penalty or by any legal or equitable proceeding or otherwise howsoever; all
such liability being, by the acceptance hereof and as a part of the
consideration for the issuance hereof, expressly waived and released by every
holder hereof; provided, however, that nothing herein or in the Indenture
contained shall be taken to prevent recourse to and the enforcement of the
liability, if any, of any stockholder or subscriber to capital stock upon or in
respect of shares of capital stock not fully paid.

         This Bond is transferable by the registered owner hereof, in person or
by attorney authorized in writing, at the corporate trust office of the
Trustee, and at such other offices or agencies as may be required to be
maintained for such purpose to comply with the rules of any securities exchange
on which the Bonds of this Series may at the time be listed, upon surrender of
this Bond, and upon any such transfer of a new Bond or Bonds, of the same
series for the same aggregate principal amount, will be issued to the
transferee in exchange herefor, without payment of any charge other than stamp
taxes and other governmental charges incident thereto. The Company and the
Trustee may deem and treat the person in whose name this Bond is registered as
the absolute owner hereof, whether or not this Bond shall be overdue, for the
purpose of receiving payment as herein provided and for all other purposes.

         The Bonds of this Series are issuable as registered Bonds without
coupons in denominations of $1,000 and/or any multiple thereof authorized by
the Company. As provided in the Indenture, Bonds of this Series are
exchangeable for other Bonds of this Series of a different authorized
denomination or denominations, as requested by the holder surrendering the
same, without payment of any charge other than stamp taxes and other
governmental charges incident thereto.

         The Company shall not be required to make any transfer or exchange of
this Bond for a period of 10 days next preceding the mailing of notice of
redemption of any Bonds of this Series.

         The Bonds of this Series are subject to redemption upon prior notice
given as provided in the Indenture, upon payment of one hundred per centum
(100%) of the principal amount so redeemed together with interest accrued
thereon to the date fixed for redemption in the event that all or substantially
all of the Electric Property or all or substantially all of the Gas Property of
the Company shall be released or substantially all of the Trust Estate (with
certain exceptions) shall be taken by eminent domain or sold in anticipation of
such taking.

         Bonds for whose redemption and payment provision is made in accordance
with the Indenture shall thereupon cease to be entitled to the lien of the
Indenture and shall cease to bear interest from and after the date fixed for
redemption.

insert -- The principal of this Security shall not bear interest except in the
case of a default in payment of principal or premium, if any, upon
acceleration, upon redemption or at Stated Maturity and in such case the
overdue principal and premium, if any, of this Security shall bear interest at
the rate of [yield to maturity]% per annum (to the extent that the payment of
such interest shall be legally enforceable), which shall accrue from the date
of such default in payment to the date payment of such principal and premium,

overdue principal and premium, if any, that is not so paid on demand shall bear
interest at the rate of [yield to maturity]% per annum (to the extent that the
payment of such interest shall be legally enforceable), which shall accrue from
the date of such demand for payment to the date payment of such interest has
been made or duly provided for, and such interest shall also be payable on
demand.]

                 Payment of the principal of (and premium, if any) and
interest, if any, on this Security will be made at the office or agency of the
Company maintained for that purpose in the Borough of Manhattan, The City of

time of payment is legal tender for the payment of public and private debts;
provided, however, that at the option of the Company payment of interest may be
made by check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register.

                 Reference is hereby made to the further provisions of this
Security set forth on the reverse hereof, which further provisions shall for
all purposes have the same effect as if set forth at this place.

                 Unless the certificate of authentication hereon has been
executed by the Trustee referred to on the reverse hereof, or an Authenticating
Agent, by manual signature of one of its authorized officers, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

                  [LONG ISLAND LIGHTING COMPANY LETTERHEAD]

                                                            April 4, 1994



Long Island Lighting Company
175 East Old Country Road
Hicksville, New York 11801

         Re:  Debt and Equity Securities

Gentlemen:

         As General Counsel for Long Island Lighting Company (the "Company"), I
am familiar with the proposed issuance by the Company of General & Refunding
Bonds, Debentures, Preferred Stock and Common Stock in the aggregate principal
amount of up to $803,550,000 (the "Securities").  This amount includes
$299,550,000 of Securities previously registered and unissued under
Registration No. 33-60744 and $4,000,000 of General and Refunding Bonds
previously registered and unissued under Registration No. 33-45834.  In
connection with the proceedings before the Securities and Exchange Commission
with respect hereto, I submit this opinion and hereby consent to its use as
Exhibit 5 to the Shelf Registration Statement on Form S-3 for the issuance of
up to an additional $500,000,000 of Securities proposed to be filed by the
Company under the Securities Act of 1933, as amended (the "New Registration
Statement"), and to the use of my name herein and in the Prospectus forming a
part thereof (the "Prospectus").

         I have examined and am familiar with (i) the Restated Certificate of
Incorporation and By-laws of the Company, the Registration Statement and the
Prospectus and (ii) with the Petitions dated October 7, 1991, January 22, 1993,
and January 6, 1994 that have been filed by the Company with the Public Service
Commission of the State of New York (the "PSC") requesting authority to sell
and issue the Securities (the "Petitions"); and I have reviewed the proceedings
taken with respect to the authorization, issuance and sale of the Securities.

         Based upon the foregoing and upon my general familiarity with the
affairs of the Company, I advise you that in my opinion:

         I.  The Company is a corporation duly organized and validly existing
under the laws of the State of New York.

        II.  No State regulatory body or agency, other than the PSC, has
jurisdiction over the transactions proposed by the Company or any part thereof.
<PAGE>   2
                                       2



   III.  No federal commission or agency other than the Securities and Exchange
Commission, under the Securities Act of 1933, as amended, has jurisdiction over
the transactions proposed by the Company or any part thereof.

    IV.  All action necessary to make valid the sale and issuance of the
Securities will have been taken when (a) the New Registration Statement
relating thereto (and any amendments, post-effective amendments, the Prospectus
or any prospectus supplements) shall have become effective; (b) orders have
been issued by the PSC authorizing the relief requested in the Petition; (c)
the Board of Directors of the Company shall have taken appropriate action to
authorize the execution, delivery, issuance and sale of the Securities; (d) if
the Securities are issued as General and Refunding Bonds, the proposed
Supplemental Indenture to the G&R Indenture shall have been qualified under the
Trust Indenture Act of 1939 and duly executed and delivered; (e) if the
Securities are issued as Debentures, the proposed Supplemental Indenture to the
appropriate Debenture Indenture shall have been qualified under the Trust
Indenture Act of 1939 and duly executed and delivered; (f) the Securities shall
have been executed by the Company, and, if applicable, authenticated by the
Trustee and delivered for value; (g) if the Securities are issued as Preferred
Stock, the Company shall have filed with the State of New York, a Certificate
of Amendment to the Company's Restated Certificate of Incorporation stating the
number, designation, relative rights, preference and limitations of such series
of the Preferred Stock with the consent and approval of the PSC endorsed
thereunder; and (h) if the Securities are issued as either Preferred Stock or
Common Stock, the Company shall have received the full consideration (not less
than the par value thereof) for each share.

     V.  When the foregoing steps shall have been taken with respect to the
Securities and the Securities have been sold, the Securities will be legally
issued, fully paid and non-assessable and will constitute legal, valid and
binding obligations of the Company enforceable in accordance with their terms.

                                                   Very truly yours,

                                                   /s/ ROBERT J. GREY
