Debt Securities will accrue or the method of determination of such date or
dates, the dates on which such interest, if any, will be payable, and the
regular record dates for such interest payment dates, if any; (vii) the place
or places where the principal of and any premium and interest on the Offered
Debt Securities will be payable; (viii) the period or periods within which,
the price or prices at which and the terms and conditions upon which the
Offered Debt Securities may be redeemed, in whole or in part, at the option of
the Company; (ix) the obligation, if any, of the Company to redeem or purchase
Offered Debt Securities pursuant to any sinking fund or analogous provisions
or at the option of a Holder, and the periods within which, the price or

amount of payments of principal of or any premium or interest on the Offered
Debt Securities may be determined with reference to an index, the manner in
which such amounts will be determined; (xiii) if the principal of or any

conditions upon which such election is to be made; (xiv) if other than the

                                       4
<PAGE>
 
  Unless otherwise provided and except with respect to Book-Entry Securities,
principal of and premium, if any, and interest, if any, on Debt Securities
will be payable, and the transfer of Debt Securities will be registrable, at
the Corporate Trust Office of the Trustee, except that, at the option of the
Company, interest may be paid by mailing a check to, or by wire transfer to,
the Holders entitled thereto. (Sections 301 and 305)
 
  For a description of payments of principal of, and premium, if any, and
interest on, and transfer of, Book-Entry Securities, and exchanges of Global

  Unless otherwise indicated in the Prospectus Supplement relating thereto and
except with respect to Book-Entry Securities, Debt Securities will be issued
only in fully registered form without coupons and only in denominations of
$1,000 and any integral multiple thereof. No service charge will be made for
any registration of transfer or exchange of Debt Securities, but the Company
may require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith. (Sections 302 and 305)
 
  Debt Securities may be issued under the Indenture as Original Issue Discount
Securities to be offered and sold at a substantial discount below their stated
principal amount. Federal income tax consequences and other special
considerations applicable to any such Original Issue Discount Securities will
be described in the Prospectus Supplement relating thereto. "Original Issue
Discount Security" means any Debt Security which provides for an amount less
than the principal amount thereof to be due and payable upon a declaration of
acceleration of the maturity thereof. (Section 101)
 
CERTAIN COVENANTS OF THE COMPANY
 
 Restriction on Liens
 
  The Indenture provides that the Company will not, and will not permit any
Restricted Subsidiary to, issue, assume or guarantee any Debt which is secured
by a mortgage, pledge, security interest or lien (any mortgage, pledge,
security interest or lien being hereinafter referred to as a "lien" or
"liens") upon any Principal Property of the Company or of any Restricted
Subsidiary or upon any shares of stock or Debt issued by any Restricted
Subsidiary, whether now owned or hereafter acquired, without effectively
providing that the Debt Securities entitled to the benefits of this covenant
(together with, if the Company so determines, any other indebtedness of or
guaranty by the Company or such Restricted Subsidiary then existing or
thereafter created which is not subordinated to the Debt Securities) will be
secured equally and ratably with (or at the Company's option, prior to) such
secured Debt so long as such Debt is so secured; provided, however, that the
foregoing will not restrict or apply to Debt secured by (a) liens on property
of, or shares of stock or Debt issued by, any Subsidiary existing at the time
such Subsidiary becomes a Restricted Subsidiary; provided, that such lien has
not been incurred in connection with the transfer by the Company or a
Restricted Subsidiary of a Principal Property to such Subsidiary unless the
Company, within 180 days of the effective date of such transfer, applies or
causes a Restricted Subsidiary to apply an amount equal to the fair value, as
determined by the Board of Directors, of such Principal Property at the time
of such transfer, to the retirement of Debt Securities or other Debt of the
Company (other than Debt subordinated to the Debt Securities), or Debt of any
Restricted Subsidiary (other than Debt owed to the Company or any Restricted
Subsidiary), having a stated maturity (i) more than 12 months from the date of
such application or (ii) which is extendable at the option of the obligor
thereon to a date more than 12 months from the date of such applications; (b)
liens on any property or shares of stock or Debt existing at the time of
acquisition thereof by the Company or a Restricted Subsidiary, or liens to
secure the payment of all or any part of the purchase price or construction
cost thereof or to secure any Debt incurred prior to, at the time of, or
within 180 days after, the acquisition of such property, shares of stock or
Debt or the completion of any such construction, whichever is later, for the
purpose of financing all or any part of the purchase price or construction
cost thereof; (c) liens on any property to secure all or any part of the cost
of development, construction, alteration, repair or improvement of all or any
part of such property, or to secure Debt incurred prior to, at the time of, or
within 180 days after, the completion of such development, construction,
alteration, repair or improvement, whichever is later, for the purpose of
financing all or any part of such cost; (d) liens which secure

 Restriction on Sale and Leaseback Transactions
 
  The Indenture further provides that the Company will not, and will not
permit any Restricted Subsidiary to, enter into any arrangement after June  ,
1996 with any bank, insurance company or other lender or investor (other than
the Company or another Restricted Subsidiary) providing for the leasing as
lessee by the Company or a Restricted Subsidiary of any Principal Property
(except a lease for a term not to exceed three years by the end of which term
it is intended that the use of such Principal Property by the lessee will be
discontinued and a lease which secures or relates to industrial revenue or
pollution control bonds or similar financing), which was or is owned by the
Company or a Restricted Subsidiary and which has been or is to be sold or
transferred by the Company or a Restricted Subsidiary to such Person more than
180 days after the completion of construction and commencement of full
operation of such property by the Company or such Restricted Subsidiary, to
such lender or investor or to any Person to whom funds have been or are to be
advanced by such lender or investor on the security of such Principal Property
(herein referred to as a "Sale and Leaseback Transaction"), unless (a) the

through (i) set forth under "Restrictions on Liens" above, without equally and
ratably securing the Debt Securities to issue, assume or guarantee Debt
secured by a lien on such Principal

Property in the amount of the Attributable Debt arising from such Sale and
Leaseback Transaction without equally and ratably securing the Debt Securities
pursuant to the Indenture; or (b) the Attributable Debt of the Company and its
Restricted Subsidiaries in respect of such Sale and Leaseback Transaction and
all other Sale and Leaseback Transactions entered into after June  , 1996
(other than such Sale and Leaseback Transactions as are permitted as described
in clause (a) above or clause (c) below), plus the aggregate principal amount
of Debt secured by liens on Principal Properties then outstanding (not
including any such Debt secured by liens described in clauses (a) through (i)
set forth under "Restrictions on Liens" above) which do not equally and
ratably secure the Debt Securities, would not exceed 10% of Consolidated Net
Tangible Assets; or (c) the Company, within 180 days after any such sale or
transfer, applies or causes a Restricted Subsidiary to apply an amount equal
to the greater of the net proceeds of such sale or transfer or the fair value,
as determined by the Board of Directors, of the Principal Property so sold and
leased back at the time of entering into such Sale and Leaseback Transaction
to the retirement of Debt Securities or other Debt of the Company (other than
Debt subordinated to the Debt Securities), or Debt of any Restricted
Subsidiary (other than Debt owed to the Company or any Restricted Subsidiary),
having a stated maturity (i) more than 12 months from the date of such
application or (ii) which is extendable at the option of the obligor thereon
to a date more than 12 months from the date of such application; provided,
that the amount to be so applied will be reduced by (x) the principal amount
of Debt Securities delivered to the Trustee for retirement and cancellation
within 180 days after such sale or transfer, and (y) the principal amount of
any such Debt of the Company or a Restricted Subsidiary other than Debt
Securities voluntarily retired by the Company or a Restricted Subsidiary
within 180 days after such sale or transfer. Notwithstanding the foregoing, no
retirement referred to in clause (c) of the preceding sentence may be effected
by payment at Maturity. (Section 1005)

borrower, and deferred income taxes which are classified as current
liabilities, all as reflected in the audited consolidated balance sheet
contained in the Company's most recent annual report to its shareholders under
Rule 14a-3 of the Exchange Act, prior to the time as of which "Consolidated
Net Tangible Assets" is being determined.
 
  "Debt" means indebtedness for borrowed money.
 
  "Person" means, except as provided in Article Six of the Indenture, any

EVENTS OF DEFAULT
 
  An Event of Default with respect to the Debt Securities of any series is
defined in the Indenture as: (a) default in payment of interest on any Debt
Security of that series, which continues for 30 days; (b) default in payment
of principal of or premium, if any, on any Debt Security of that series at
maturity; (c) default in the deposit of any sinking fund payment when due in
respect of that series; (d) default in the performance or breach of any other
covenant of the Company in the Indenture (other than a default in the
performance or breach of a covenant included in the Indenture solely for the
benefit of a series of Debt Securities other than that series), which
continues for 60 days after due notice (as described in the Indenture) by the
Trustee or by Holders of at least 10% in principal amount of the Outstanding
Debt Securities of that series; (e) default under any bond, debenture, note or
other evidence of indebtedness for money borrowed by the Company (including a
default with respect to Debt Securities of any series other than that series)
or any Subsidiary in an aggregate principal amount of at least $25,000,000 or
under any mortgage, indenture or instrument under which there may be issued or
by which there may be secured or evidenced any indebtedness for money borrowed
by the Company (including the Indenture) or any Subsidiary in an aggregate
principal amount of at least $25,000,000, whether such indebtedness now exists
or hereafter is created, which default constitutes a failure to pay any
portion of the principal of such indebtedness when due and payable after the
expiration of any applicable grace period with respect thereto or has resulted
in such indebtedness becoming or being declared due and payable prior to the
date on which it would otherwise have become due and payable, without such
acceleration having been rescinded or annulled, or such indebtedness having
been discharged, within a period of 30 days after there shall have been given,
by registered or certified mail to the Company by the Trustee, or to the
Company and the Trustee by the Holders of at least 10% in principal amount of
the Outstanding Securities of that series, a written notice specifying such
default and requiring the Company to cause such acceleration to be rescinded
or annulled or such indebtedness to be discharged and stating that such notice
is a Notice of Default under the Indenture; provided, however, that, subject
to the provisions of Sections 601 and 602 of the Indenture, the Trustee will
not be deemed to have knowledge of such default unless either (i) a
responsible officer of the Trustee has actual knowledge of such default or
(ii) the Trustee has received written notice of such default from the Company,
from any Holder, from the holder of any such indebtedness or from the trustee
under any such mortgage, indenture or other instrument; (f) certain events of
bankruptcy, insolvency or reorganization of the Company; and (g) any other
Event of Default provided with respect to Debt Securities of that series.
(Section 501)
 
  The Indenture provides that, if any Event of Default with respect to Debt
Securities of any series at the time Outstanding occurs and is continuing,
either the Trustee or the Holders of not less than 25% in principal amount of
the Outstanding Debt Securities of that series may declare the principal
amount (or, if any of the Debt Securities of that series are Original Issue
Discount Securities, such portion of the principal amount of such Debt
Securities as may be specified in the terms thereof) of (and all accrued and
unpaid interest on) all Debt Securities of that series to be due and payable
immediately, but under certain conditions such declaration may be rescinded
and annulled and past defaults (except, unless theretofore cured, a default in
payment of principal of or premium, if any, or interest, if any, on the Debt
Securities of that series and certain other specified defaults) may be waived
 
                                       8
<PAGE>
 
by the Holders of not less than a majority in principal amount of the
Outstanding Debt Securities of that series on behalf of the Holders of all
Debt Securities of that series. (Sections 502 and 513)
 
  The Indenture provides that if a default occurs under the Indenture with
respect to Debt Securities of any series at the time Outstanding, the Trustee
will give the Holders of the Outstanding Debt Securities of that series notice
of such default as and to the extent provided by the Trust Indenture Act of
1939, as amended (the "Trust Indenture Act"); provided, however, that such
notice will not be given with respect to Outstanding Debt Securities of any
series until at least 30 days after the occurrence of that default if that
default is in the performance of a covenant in the Indenture other than for
the payment of the principal of or premium, if any, or interest on any Debt
Security of such series or the deposit of any sinking fund payment with
respect to the Debt Securities of such series. For the purpose of the
provision described in this paragraph, the term default with respect to any
series of Outstanding Debt Securities means any event which is, or after
notice or lapse of time or both would become, an "Event of Default" specified
in the Indenture with respect to Debt Securities of such series. (Section 602)
 
  The Indenture contains a provision entitling the Trustee to be indemnified
by the Holders of any series of Outstanding Debt Securities before proceeding
to exercise any right or power vested in it under the Indenture at the request
or direction of the Holders of such series of Debt Securities. (Section 603)
The Trustee is required, during a default, to act with the standard of care
provided in the Trust Indenture Act. (Section 601) The Indenture provides that
the Holders of a majority in principal amount of Outstanding Debt Securities
of any series may 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 with respect to the Debt Securities of such
series; provided, that the Trustee may decline to act if: (a) such direction
is contrary to law or the Indenture; (b) the Trustee in good faith determines
that the action so directed would involve the Trustee in personal liability
for which it has not been adequately indemnified or would be unduly
prejudicial to Holders not joining in such direction. (Section 512)
 
  The Indenture includes a covenant that the Company will file annually with
the Trustee a certificate concerning its compliance with the Indenture.
(Section 1009)
 
MODIFICATION OF THE INDENTURE AND WAIVER OF COVENANTS
 
  Modifications and amendments may be made by the Company and the Trustee to
the Indenture, without the consent of any Holder of any Debt Security of any
series, to add covenants and Events of Default, and to make provisions with
respect to other matters and issues arising under the Indenture, provided that
any such provision does not adversely affect the rights of the Holders of Debt
Securities of any series in any material respect. (Section 901)
 
  The Indenture contains provisions permitting the Company and the Trustee,
with the consent of the Holders of not less than 66 2/3% in principal amount
of Outstanding Debt Securities of each series affected thereby, to execute
supplemental indentures adding any provisions to or changing or eliminating
any of the provisions of the Indenture or modifying the rights of the Holders
of Outstanding Debt Securities of such series, except that no such
supplemental indenture may, without the consent of the Holder of each
Outstanding Debt Security affected thereby, (a) change the Stated Maturity of
the principal of, or any installment of principal of or interest on, any Debt
Security, or reduce the principal amount thereof, the premium, if any, thereon
or the rate of interest thereon, of any Debt Security of any series, (b)
reduce the percentage in principal amount of Outstanding Debt Securities of
any series, the consent of the Holders of which is required for any
supplemental indenture or for waiver of compliance with certain provisions of
the Indenture or certain defaults thereunder or (c) effect certain other
changes. (Section 902) The Indenture also permits the Company to omit
compliance with certain covenants in the Indenture with respect to the Debt
Securities of any series upon waiver by the Holders of not less than 66 2/3%
in principal amount of Outstanding Debt Securities of such series. (Section
1010)

CONSOLIDATION, MERGER AND SALE OF ASSETS
 
  The Company may not consolidate with or merge into any other Person or
convey, transfer or lease its properties and assets substantially as an
entirety to any Person and the Company may not permit any Person to
consolidate with or merge into the Company, unless: (a) in case the Company
consolidates with or merges into another Person or conveys, transfers or
leases its properties and assets substantially as an entirety to any Person,
the Person formed by such consolidation or into which the Company is merged or
the Person which acquires by conveyance or transfer, or which leases, the
properties and assets of the Company substantially as an entirety is a
corporation, partnership or trust, organized and validly existing under the
laws of the United States, any state thereof or the District of Columbia and
expressly assumes the Company's obligations on the Outstanding Debt Securities
and under the Indenture; (b) immediately after giving effect to such
transaction and treating any indebtedness which is an obligation of the
successor Person or becomes an obligation of the Company or a Subsidiary as a
result of such transaction as having been incurred by the Company or such
Subsidiary at the time of such transaction, no Event of Default, and no event
which, after notice or lapse of time or both, would become an Event of
Default, would have happened and be continuing; (c) if, as a result of any
such consolidation or merger or such conveyance, transfer or lease, properties
or assets of the Company would become subject to a lien which would not be
permitted by the Indenture, the Company or such successor Person, as the case
may be, takes such steps as are necessary effectively to secure the Debt
Securities equally and ratably with (or prior to) all indebtedness secured
thereby; and (d) the Company delivers to the Trustee an officers' certificate
and an opinion of counsel, each stating that such consolidation, merger,
conveyance, transfer or lease and, if a supplemental indenture is required in
connection with the transaction, such supplemental indenture comply with the
Indenture and that all conditions precedent in the Indenture provided for
relating to such transaction have been complied with.
 
BOOK-ENTRY SECURITIES
 
  The following description of Book-Entry Securities will apply to any series
of Debt Securities issued in whole or in part in the form of a Global Security
or Securities except as otherwise provided in the Prospectus Supplement
relating thereto.
 
  Upon issuance, all Book-Entry Securities of like tenor and having the same
date of original issue will be represented by one or more Global Securities.
Each Global Security representing Book Entry Securities will be deposited
with, or on behalf of, the Depositary, which will be a clearing agent
registered under the Exchange Act. The Global Security will be registered in
the name of the Depositary or a nominee of the Depositary.
 
  Ownership of beneficial interests in a Global Security representing Book-
Entry Securities will be limited to institutions that have accounts with the
Depositary or its nominee ("participants") or persons that may hold beneficial
interests through participants. In addition, ownership of beneficial interests
by participants in such a Global Security only will be evidenced by, and the
transfer of those ownership interests only will be effected through, records
maintained by the Depositary or its nominee for such Global Security.
Ownership of beneficial interests in such a Global Security by persons that
hold through participants only will be evidenced by, and the transfer of those
ownership interests within such participant only will be effected through,
records maintained by such participant. The laws of some jurisdictions require
that certain purchasers of securities take physical delivery of such
securities in definitive form. Such laws may impair the ability to transfer
beneficial interests in such a Global Security.
 
  Payment of principal of and any premium and interest on Book-Entry
Securities represented by a Global Security registered in the name of or held
by the Depositary or its nominee will be made to the Depositary or its
nominee, as the case may be, as the registered owner and holder of the Global
Security representing such Book-Entry Securities. None of the Company, the
Trustee or any agent of the Company or the Trustee will have any
responsibility or liability for any aspect of the Depositary's records or any
participant's records relating to, or payments made on account of, beneficial
ownership interests in a Global Security representing such Book-Entry
Securities or for maintaining, supervising or reviewing any of the
Depositary's records or any participant's
 
                                      10
<PAGE>
 
records relating to such beneficial ownership interests. Payments by
participants to owners of beneficial interests in a Global Security held
through such participants will be governed by the Depositary's procedures, as
is now the case with securities held for the accounts of customers registered
in "street name," and will be the sole responsibility of such participants.
 
  No Global Security described above may be transferred except as a whole by
the Depositary for such Global Security to a nominee of the Depositary or by a
nominee of the Depositary to the Depositary or another nominee of the
Depositary or by the Depositary or any such nominee of the Depositary to a
successor Depositary or a nominee of such successor Depositary.
 
  A Global Security representing Book-Entry Securities is exchangeable for
definitive Debt Securities in registered form, of like tenor and of an equal
aggregate principal amount, if (a) the Depositary notifies the Company that it
is unwilling or unable to continue as depositary for such Global Security or
if at any time the Depositary ceases to be a clearing agency registered under
the Exchange Act, (b) the Company in its sole discretion determines that such
Global Security shall be exchangeable for definitive Debt Securities in
registered form or (c) there shall have occurred and be continuing an Event of
Default with respect to the Debt Securities of such series. Any Global
Security that is exchangeable pursuant to the preceding sentence will be
exchangeable in whole for definitive Debt Securities in registered form, of
like tenor and of an equal aggregate principal amount, and, unless otherwise
specified in the Prospectus Supplement relating thereto, in denominations of
$1,000 and integral multiples thereof. Such definitive Debt Securities will be
registered in the name or names of such person or persons as the Depositary
instructs the Trustee. It is expected that such instructions may be based upon
directions received by the Depositary from its participants with respect to
ownership of beneficial interests in such Global Security.
 
  Except as provided above, owners of beneficial interests in a Global
Security will not be entitled to receive physical delivery of Debt Securities
in definitive form and will not be considered the Holders thereof for any
purpose under the Indenture and no Global Security representing Book-Entry
Securities will be exchangeable, except for another Global Security of like
denomination and tenor to be registered in the name of the Depositary or its
nominee. Accordingly, each person owning a beneficial interest in a Global
Security must rely on the procedures of the Depositary and, if such person is
not a participant, on the procedures of the participant through which such
person owns its interest, to exercise any rights of a Holder under the
Indenture. The Company understands that under existing industry practices in
the event that the Company requests any action of Holders or an owner of a
beneficial interest in such Global Security desires to give or take any action
that a Holder is entitled to give or take under the Indenture, the Depositary
would authorize the participants holding the relevant beneficial interests to
give or take such action, and such participants would authorize beneficial
owners owning through such participants to give or take such action or would
otherwise act upon the instructions of beneficial owners owning through them.
 
DISCHARGE OR DEFEASANCE OF DEBT SECURITIES IN CERTAIN CIRCUMSTANCES
 
  Defeasance and Discharge. The Indenture will cease to be of further effect
(except as to any surviving rights for the registration of the transfer or
exchange of Debt Securities expressly provided for in the Indenture) if: (a)
all Outstanding Debt Securities (other than destroyed, lost or stolen Debt
Securities which have been replaced or paid and Debt Securities, the payment
for which has been held in trust and thereafter repaid to the Company or
discharged from such trust) have been delivered to the Trustee for
cancellation or (b) (1) all Debt Securities not previously delivered to the
Trustee for cancellation have become due and payable or are by their terms to
become due and payable within one year or are to be called for redemption
within one year under arrangements satisfactory to the Trustee and (2) the
Company has deposited with the Trustee, as trust funds, an amount sufficient
to pay and discharge the entire indebtedness on the Outstanding Debt
Securities for principal and any premium and interest to the date of such
deposit or to maturity or redemption, as the case may be. Such trust may only
be established if (a) the Company has paid or caused to be paid all other sums
payable by the Company under the Indenture and (b) the Company has delivered
to the Trustee an officers' certificate and an
 
                                      11
<PAGE>
 
opinion of counsel, each stating that all conditions precedent provided for in
the Indenture relating to the satisfaction and discharge of the Indenture have
been complied with.
 
  The Indenture provides that the terms of any series of Debt Securities may
provide the Company with the option to discharge its indebtedness represented
by such series of Debt Securities or to cease to be obligated to comply with
certain covenants under the Indenture. The Company, in order to exercise such
option, will be required to deposit with the Trustee money and/or U.S.
Government Obligations which, through the payment of interest and principal in
respect thereof in accordance with their terms, will provide money in an
amount sufficient, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification delivered
to the Trustee, to pay the principal of and premium, if any, and interest on,
and any mandatory sinking fund payments in respect of, the Debt Securities of
such series at the stated maturity of such payments in accordance with the
terms of the Indenture and such Debt Securities. Such trust may only be
established if (a) in the case of Debt Securities of any series which are then
listed on the New York Stock Exchange, the Company has delivered to the
Trustee an opinion of counsel, stating that the Company's exercise of this
defeasance option will not cause the Debt Securities to be delisted; (b) no
Event of Default or event (including such deposit in trust) that with notice
or lapse of time or both would become an Event of Default with respect to Debt
Securities of a series has occurred and is continuing on the date of such
deposit; (c) the Company has delivered to the Trustee (1) an opinion of
counsel, stating that the Holders of Debt Securities of such series will not
recognize income, gain or loss for Federal income tax purposes as a result of
the Company's exercise of this defeasance option and will be subject to
Federal income tax on the same amounts and in the same manner and at the same
times as would have been the case if the Company had not exercised this option
and (2) in the case of Debt Securities of such series being discharged, either
a private letter ruling to that effect received from the U.S. Internal Revenue
Service (the "IRS") or a revenue ruling pertaining to a comparable form of
transaction to that effect published by the IRS or evidence of a change in
applicable Federal income tax law occurring after the date of the Indenture;
and (d) if the Company is to be discharged with respect to Debt Securities of
such series, no Event of Default or event that with notice or lapse of time or
both would become an Event of Default with respect to Debt Securities of such
series has occurred and is continuing at any time during the period ending on
the 123rd day after the date of deposit by the Company. (Section 1302) In the
event the Company exercises this option and the Debt Securities of a series
are declared due and payable because of the occurrence of any Event of
Default, the amount of money and U.S. Government Obligations, as the case may
be, on deposit with the Trustee will be sufficient to pay the amounts due on
the Debt Securities of a series at the time of their maturity but may not be
sufficient to pay the amounts due on the Debt Securities of such series at the
time of the acceleration resulting from such Event of Default. However, the
Company will remain liable for such payments.
 
TRUSTEE
 
  The Trustee may resign or be removed with respect to one or more series of
Debt Securities and a successor Trustee may be appointed to act with respect
to such series. (Section 610) In the event that two or more persons are acting
as trustee with respect to different series of Debt Securities, each such
Trustee will be a trustee of a trust under the Indenture separate and apart
from the trust administered by any other such Trustee (Section 611), and any
action described herein to be taken by the "Trustee" may then be taken by each
such Trustee with respect to, and only with respect to, the one or more series
of Securities for which it is Trustee.
 
                             PLAN OF DISTRIBUTION
 
  The Company may sell the Debt Securities being offered hereby in any of four
ways: (i) through agents, (ii) through underwriters, (iii) through dealers or
(iv) directly to purchasers.
 
  Offers to purchase Debt Securities may be solicited directly by the Company
or by agents designated by the Company from time to time. Any such agent, who
may be deemed to be an underwriter as that term is defined in the Securities

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Sections 1741 and 1742 of the Pennsylvania Business Corporation Law of 1988,
as amended (the "PBCL"), provide that a business corporation shall have the
power to indemnify any person who was or is a party, or is threatened to be
made a party, to any proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that such person is or was a director,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of
another corporation or other enterprise, against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such proceeding, if such
person acted in good faith and in a manner he reasonably believed to be in, or
not opposed to, the best interests of the corporation, and, with respect to
any criminal proceeding, had no reasonable cause to believe his conduct was
unlawful. In the case of an action by or in the right of the corporation, such
indemnification is limited to expenses (including attorneys' fees) actually
and reasonably incurred by such person in connection with the defense or
settlement of such action, except that no indemnification shall be made in
respect of any claim, issue or matter as to which such person has been
adjudged to be liable to the corporation unless, and only to the extent that,
a court determines upon application that, despite the adjudication of
liability but in view of all the circumstances, such person is fairly and
reasonably entitled to indemnity for the expenses that the court deems proper.
 
  PBCL Section 1744 provides that, unless ordered by a court, any
indemnification referred to above shall be made by the corporation only as
authorized in the specific case upon a determination that indemnification is
proper in the circumstances because the indemnitee has met the applicable
standard of conduct. Such determination shall be made:
 
  (1) by the Board of Directors by a majority vote of a quorum consisting of
      directors who were not parties to the proceeding; or
 
  (2) if such a quorum is not obtainable, or if obtainable and a majority
      vote of a quorum of disinterested directors so directs, by independent
      legal counsel in a written opinion; or
 
  (3) by the shareholders.
 
  Notwithstanding the above, PBCL Section 1743 provides that to the extent
that a director, officer, employee or agent of a business corporation is
successful on the merits or otherwise in defense of any proceeding referred to
above, or in defense of any claim, issue or matter therein, such person shall
be indemnified against expenses (including attorneys' fees) actually and
reasonably incurred by such person in connection therewith.
 
                                     II-1
<PAGE>
 
  PBCL Section 1745 provides that expenses (including attorneys' fees)
incurred by an officer, director, employee or agent of a business corporation
in defending any such proceeding may be paid by the corporation in advance of
the final disposition of the proceeding upon receipt of an undertaking to
repay the amount advanced if it is ultimately determined that the indemnitee
is not entitled to be indemnified by the corporation.
 
  PBCL Section 1746 provides that the indemnification and advancement of
expenses provided by, or granted pursuant to, the foregoing provisions is not
exclusive of any other rights to which a person seeking indemnification may be
entitled under any bylaw, agreement, vote of shareholders or disinterested
directors or otherwise, and that indemnification may be granted under any
bylaw, agreement, vote of shareholders or directors or otherwise for any
action taken or any failure to take any action whether or not the corporation
would have the power to indemnify the person under any other provision of law
and whether or not the indemnified liability arises or arose from any action
by or in the right of the corporation; provided, however, that no
indemnification may be made in any case where the act or failure to act giving
rise to the claim for indemnification is determined by a court to have
constituted willful misconduct or recklessness.
 
  Article IV of the By-Laws of the Company provides that the directors,
officers, agents and employees of the Company shall be indemnified as of right
to the fullest extent now or hereafter not prohibited by law in connection
with any actual or threatened action, suit or proceeding, civil, criminal,
administrative, investigative or other (whether brought by or in the right of
the Company or otherwise) arising out of their service to the Company or to
another enterprise at the request of the Company.
 
  PBCL Section 1747 permits a Pennsylvania business corporation to purchase
and maintain insurance on behalf of any person who is or was a director,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of
another corporation or other enterprise, against any liability asserted
against such person and incurred by him in any such capacity, or arising out
of his status as such, whether or not the corporation would have the power to
indemnify the person against such liability under the provisions described
above.
 
  Article IV of the By-Laws of the Company provides that the Company may
purchase and maintain insurance to protect itself and any director, officer,
agent or employee entitled to indemnification under that Article IV against
any liability asserted against such person and incurred by such person in
respect of the service of such person to the Company, whether or not the
Company would have the power to indemnify such person against such liability
by law or under the provisions of that Article IV.
 
  The Company maintains directors' and officers' liability insurance covering
its directors and officers with respect to liabilities, including liabilities
under the Securities Act of 1933, as amended, which they may incur in
connection with their serving as such. Under this insurance, the Company may
receive reimbursement for amounts as to which the directors and officers are
indemnified by the Company under the foregoing By-Law indemnification
provision. Such insurance also provides certain additional coverage for the
directors and officers against certain liabilities even though such
liabilities may not be covered by the foregoing By-Law indemnification
provision.
 
  As permitted by PBCL Section 1713, the Articles and By-Laws of the Company
provide that no director shall be personally liable for monetary damages for
any action taken, or failure to take any action, unless such director's breach
of duty or failure to perform constituted self-dealing, willful misconduct or
recklessness. The PBCL states that this exculpation from liability does not
apply to the responsibility or liability of a director pursuant to any
criminal statute or the liability of a director for the payment of taxes
pursuant to Federal, state or local law. It may also not apply to liabilities
imposed upon directors by the Federal securities laws. PBCL Section 1715(d)
creates a presumption, subject to exceptions, that a director acts in the best
interests of the corporation. PBCL Section 1712, in defining the standard of
care a director owes to the corporation, provides that a director stands in a
fiduciary relation to the corporation and must perform his duties as a
director or as a member of any committee of the Board in good faith, in a
manner he reasonably believes to be in the best interests of the corporation
and with such care, including reasonable inquiry, skill and diligence, as a
person of ordinary prudence would use under similar circumstances.

  In June, 1987, the Company entered into a separate Indemnity Agreement with
each of its then directors and officers. These Indemnity Agreements provide a
contractual right to indemnification against expenses and liabilities (subject
to certain limitations and exceptions) and a contractual right to advancement
of expenses, and contain additional provisions regarding the determination of
entitlement, settlement of proceedings, insurance, rights of contribution, and
other matters.

ITEM 17. UNDERTAKINGS.
 
 (a) Rule 415 offering.
 
  The undersigned 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, as amended (the "1933 Act");
 
    (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. Notwithstanding the
         foregoing, any increase or decrease in volume of securities
         offered (if the total dollar value of securities offered would not
         exceed that which was registered) and any deviation from the low
         or high and of the estimated maximum offering range may be
         reflected in the form of prospectus filed with the Securities and
         Exchange Commission pursuant to Rule 424(b) if, in the aggregate,
         the changes in volume and price represent no more than 20 percent
         change in the maximum aggregate offering price set forth in the
         "Calculation of Registration Fee" table in the effective
         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 (a)(1)(i) and (a)(1)(ii) do not apply if
the information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
 
                                     II-3
<PAGE>
 
Securities and Exchange Commission by the registrant pursuant to section 13 or
section 15(d) of the Securities Exchange Act of 1934, as amended (the "1934
Act"), that are incorporated by reference in the registration statement;
 
  (2) That, for the purpose of determining any liability under the 1933 Act,
      each such 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; and
 
  (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.
 
 (b) Filings incorporating subsequent 1934 Act documents by reference.
 
  The undersigned hereby undertakes that, for purposes of determining any
liability under the 1933 Act, each filing of the registrant's annual report
pursuant to section 13(a) or section 15(d) of the 1934 Act that is
incorporated by reference in the registration statement shall be deemed to be
a new registration statement relating to the securities offered herein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.
 
 (h) Request for Acceleration of Effective Date.
 
  Insofar as indemnification for liabilities arising under the 1933 Act may be
permitted to directors, officers and controlling persons of the registrant
pursuant to the provisions described under Item 15 above, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
1933 Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant 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, the registrant 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 1933
Act and will be governed by the final adjudication of such issue.
 
 (i) Rule 430A Offerings.
 
  The undersigned hereby undertakes that:
 
  (1) For purposes of determining any liability under the 1933 Act, the
      information omitted from the form of prospectus filed as part of this
      registration statement in reliance upon Rule 430A and contained in a
      form of prospectus filed by the registrant pursuant to Rule 424(b)(1)
      or (4) or 497(h) under the 1933 Act shall be deemed to be part of this
      registration statement as of the time it was declared effective.
 
  (2) For the purpose of determining any liability under the 1933 Act, each
      post-effective amendment that contains a form of prospectus 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.

To the Representatives named
in Schedule I hereto of the
Underwriters named in
Schedule II hereto


Ladies and Gentlemen:

          Equitable Resources, Inc., a Pennsylvania corporation (the "Company"),
proposes to issue and sell to the underwriters named in Schedule II hereto (the
"Underwriters"), for whom you are acting as representatives (the
"Representatives"), the principal amount of its debt securities identified in
Schedule I hereto (the "Securities"), to be issued under the indenture specified
in Schedule I hereto (the "Indenture") between the Company and the Trustee
identified in such Schedule (the "Trustee").  If the firm or firms listed in
Schedule II hereto include only the firm or firms listed in Schedule I hereto,
then the terms "Underwriters" and "Representatives", as used herein, shall each
be deemed to refer to such firm or firms.

          The Company has prepared and filed with the Securities and Exchange
Commission (the "Commission") in accordance with the provisions of the
Securities Act of 1933, as amended, and the rules and regulations of the
Commission thereunder (collectively, the "Securities Act"), two registration
statements (the file numbers of which are set forth in Schedule I hereto) on
Form S-3, relating to certain debt securities (the "Shelf Securities") to be
issued from time to time by the Company.  The Company also has filed with, or
proposes to file with, the Commission pursuant to Rule 424 under the Securities
Act a prospectus supplement specifically relating to the Securities.  The
registration statements as amended to the date of this Agreement are hereinafter
referred to as the "Registration Statement" and the related prospectus covering
the Shelf Securities in the form first used to confirm sales of the Securities
is hereinafter referred to as the "Basic Prospectus".  The Basic Prospectus as
supplemented by the prospectus supplement specifically relating to the
Securities in the form first used to confirm sales of the Securities is
hereinafter referred to as the "Prospectus".  Any reference in this Agreement to
the Registration Statement, the Basic Prospectus, any preliminary form of the
Prospectus (a "preliminary prospectus") previously filed with the Commission
pursuant to Rule 424 or the Prospectus shall be deemed to refer to and include
the documents incorporated by reference therein pursuant to Item 12 of Form S-3
under the
<PAGE>
 
Securities Act which were filed under the Securities Exchange Act of 1934, as
amended, and the rules and regulations of the Commission thereunder
(collectively, the "Exchange Act") on or before the date of this Agreement or
the date of the Basic Prospectus, any preliminary prospectus or the Prospectus,
as the case may be; and any reference to "amend", "amendment" or "supplement"
with respect to the Registration Statement, the Basic Prospectus, any
preliminary prospectus or the Prospectus shall be deemed to refer to and include
any documents filed under the Exchange Act after the date of this Agreement, or
the date of the Basic Prospectus, any preliminary prospectus or the Prospectus,
as the case may be, which are deemed to be incorporated by reference therein.

          The Company hereby agrees with the Underwriters as follows:

          1.  The Company agrees to issue and sell the Securities to the several
Underwriters as hereinafter provided, and each Underwriter, on the basis of the
representations and warranties herein contained, but subject to the conditions
hereinafter stated, agrees to purchase, severally and not jointly, from the
Company the respective principal amount of Securities set forth opposite such
Underwriter's name in Schedule II hereto at the purchase price set forth in
Schedule I hereto plus accrued interest, if any, from the date specified in
Schedule I hereto to the date of payment and delivery.

          2.  The Company understands that the several Underwriters intend (i)
to make a public offering of their respective portions of the Securities and
(ii) initially to offer the Securities upon the terms set forth in the
Prospectus.

          3.  Payment for the Securities shall be made by wire transfer in
immediately available funds to the account specified by the Company to the
Representatives, no later than noon the Business Day (as defined below) prior to
the Closing Date (as defined below), on the date and at the time and place set
forth in Schedule I hereto (or at such other time and place on the same or such
other date, not later than the fifth Business Day thereafter, as you and the
Company may agree in writing).  As used herein, the term "Business Day" means
any day other than a day on which banks are permitted or required to be closed
in New York City.  The time and date of such payment and delivery with respect
to the Securities are referred to herein as the "Closing Date".

          Payment for the Securities shall be made against delivery to the
nominee of The Depository Trust Company for the respective accounts of the
several Underwriters of the Securities of one or more global notes (the "Global
Note") representing the Securities, with any transfer taxes payable in
connection with the transfer to the Underwriters of the Securities duly paid by
the Company.  The Global Note will be made available for inspection by the
Representatives at the office of [the Trustee, address] [J.P. Morgan Securities
Inc. at the address set forth above] not later than 1:00 P.M., New York City
time, on the Business Day prior to the Closing Date.

Prospectus made in reliance upon and in conformity with information relating to

stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading; and any further
documents so filed and incorporated by reference in the Prospectus or any
further amendment or supplement thereto, when such documents become effective or
are filed with the Commission, as the case may be, will conform in all material
respects to the requirements of the Securities Act or the Exchange Act, as
applicable, and will not contain an untrue statement of a material fact or omit

consolidated subsidiaries as of the dates indicated and the results of their
operations and the changes in their consolidated cash flows for the periods

Company or any of its subsidiaries or to which the Company or any of its

tribunals, domestic or foreign, necessary to own or lease, as the case may be,
and to operate its properties and to carry on its business as conducted as of
the date hereof, except where the failure to so own or possess or to have so
obtained or made would not, singly or in the aggregate, have a material adverse
effect on the Company and its subsidiaries taken as a whole, and neither the
Company nor any such subsidiary has received any actual notice of any proceeding
relating to revocation or modification of any such license, permit, certificate,
consent, order, approval or other authorization, except as described in the
Registration Statement and the Prospectus; and each of the Company and its
subsidiaries is in compliance with all laws and regulations relating to the

and all applicable foreign, federal, state and local laws and regulations
relating to the protection of human health and safety, the environment or
hazardous or toxic substances or wastes, pollutants or contaminants
("Environmental Laws"), (ii) have received all permits, licenses or other
approvals required of them under applicable Environmental Laws to conduct their
respective businesses, (iii) are in compliance with all terms and conditions of
any such permit, license or approval, except where such noncompliance with
Environmental Laws, failure to receive required permits, licenses or other

licenses or approvals would not, singly or in the aggregate, have a material
adverse effect on the Company and its subsidiaries, taken as a whole, and (iv)
are not aware of any administrative or judicial action being contemplated by
governmental authorities relating to Environmental Laws; neither the Company nor
any of its subsidiaries are subject to any consent decree or compliance or
administrative order issued pursuant to, or are the subject of any pending

actions, decrees, orders or investigations which do not and are not reasonably
expected to have a material adverse effect on, or cause material changes to, the
general affairs, business, prospects, management, financial position,
stockholders' equity or results of operations of the Company and its
subsidiaries, taken as a whole; and neither the Company nor any of its
subsidiaries is a party to a governmental proceeding arising under any
Environmental Law which involves potential monetary sanctions, exclusive of
interest and costs, of $100,000 or more;

          (s)  in the ordinary course of its business, the Company reviews the
effect of Environmental Laws on the business, operations and properties of the

associated costs and liabilities (including, without limitation, any capital or
operating expenditures required for clean-up, closure of properties or
compliance with Environmental Laws or any permit, license or approval, any
related constraints on operating activities and any potential liabilities to
third parties); and, on the basis of such review, the Company has reasonably
concluded that such

                                      -7-

threatened labor disputes with the employees of the Company or any of its
subsidiaries which are likely to have a material adverse effect on the Company
and its subsidiaries taken as a whole; and

the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), that

affiliates for employees or former employees of the Company and its affiliates
has been maintained in compliance with its terms and the requirements of any
applicable statutes, orders, rules and regulations, including but not limited to
ERISA and the Internal Revenue Code of 1986, as amended (the "Code").  No
prohibited transaction, within the meaning of Section 406 of ERISA or Section
4975 of the Code has occurred with respect to any such plan excluding
transactions effected pursuant to a statutory or administrative exemption.  For
each such plan which is subject to the funding rules of Section 412 of the Code
or Section 302 of ERISA no "accumulated funding deficiency" as defined in
Section 412 of the Code has been incurred, whether or not waived, and the fair
market value of the assets of each such plan (excluding for these purposes
accrued but unpaid contributions) exceeded the present value of all benefits
accrued under such plan determined using reasonable actuarial assumptions.

          5.  The Company covenants and agrees with each of the several
Underwriters as follows:

          (a)  to file the Prospectus in a form approved by you pursuant to Rule

offering of the Securities as in the opinion of counsel for the Underwriters a
prospectus relating to the Securities is required by law to be delivered in
connection with sales by an Underwriter or dealer, any event shall occur as a
result of which it is necessary to amend or supplement the Prospectus in order
to make the statements therein, in the light of the circumstances when the
Prospectus is delivered to a purchaser, not misleading, or if it is necessary to
amend or supplement the Prospectus to comply with law, forthwith to prepare and
furnish, at the expense of the Company, to the Underwriters and to the dealers
(whose names and addresses you will furnish to the Company) to which Securities
may have been sold by you on behalf of the Underwriters and to any other dealers
upon request, such amendments or supplements to the Prospectus as may be
necessary so that the statements in the Prospectus as so amended or supplemented
will not, in the light of the circumstances when the Prospectus is delivered to
a purchaser, be misleading or so that the Prospectus will comply with law; and
the opinion of Kirkpatrick & Lockhart LLP described above shall be rendered to
the Underwriters at the request of the Company and shall so state therein;

          (f)  to endeavor to qualify the Securities for offer and sale under
the securities or Blue Sky laws of such jurisdictions as you shall reasonably
request and to continue such qualification in effect so long as reasonably

          (h)  until the fifth anniversary of the date hereof, to furnish to you
copies of all reports or other communications (financial or other) furnished to
holders of Securities, and copies of any reports and financial statements
furnished to or filed with the Commission or any national securities exchange;

          (i)  during the period beginning on the date hereof and continuing to
and including the Business Day following the Closing Date, not to offer, sell,
contract to sell or otherwise dispose of any debt securities of or guaranteed by
the Company which are substantially similar to the Securities;

          (f)  Augustine A. Mazzei, Jr., Senior Vice President and Chief Legal
Officer of the Company, shall have furnished to you his written opinion, dated
the Closing Date, in form and substance satisfactory to you, to the effect that:

               (i)    the Company has been duly incorporated and is validly
     existing as a corporation in good standing under the laws of its
     jurisdiction of incorporation, with power and authority (corporate and
     other) to own its properties and conduct its business as described in the
     Prospectus as amended or supplemented;

               (ii)   the Company has been duly qualified as a foreign
     corporation for the transaction of business and is in good standing under
     the laws of each other jurisdiction in which it owns or leases properties,
     or conducts any business, so as to require such qualification, other than
     where the failure to be so qualified or in good

                                      -11-
<PAGE>
 
     standing would not have a material adverse effect on the Company and its
     subsidiaries taken as a whole;

               (iii)  each of the Company's subsidiaries has been duly
     incorporated and is validly existing as a corporation under the laws of its
     jurisdiction of incorporation with power and authority (corporate and
     other) to own its properties and conduct its business as described in the
     Prospectus and has been duly qualified as a foreign corporation for the
     transaction of business and is in good standing under the laws of each
     other jurisdiction in which it owns or leases properties, or conducts any
     business, so as to require such qualification, other than where the failure
     to be so qualified and in good standing would not have a material adverse
     effect on the Company and its subsidiaries taken as a whole; and all of the
     issued shares of capital stock of each subsidiary have been duly and
     validly authorized and issued, are fully paid and non-assessable, and
     (except in the case of foreign subsidiaries, for directors' qualifying
     shares) are owned directly or indirectly by the Company, free and clear of
     all liens, encumbrances, equities or claims;

               (iv)   other than as set forth or contemplated in the Prospectus,
     there are no legal or governmental investigations, actions, suits or
     proceedings pending or, to the best of such counsel's knowledge, threatened
     against or affecting the Company or any of its subsidiaries or any of their
     respective properties or to which the Company or any of its subsidiaries is
     or may be a party or to which any property of the Company or its
     subsidiaries is or may be subject which, if determined adversely to the
     Company or any of its subsidiaries, could individually or in the aggregate
     have, or reasonably be expected to have, a material adverse effect on the
     general affairs, business, prospects, management, financial position,
     stockholders' equity or results of operations of the Company and its
     subsidiaries taken as a whole; to the best of such counsel's knowledge, no
     such proceedings are threatened or contemplated by governmental authorities
     or threatened by others; and such counsel does not know of any statutes,
     regulations, contracts or other documents that are required to be filed as
     an exhibit to the Registration Statement or required to be described in the
     Registration Statement or the Prospectus which are not filed or described
     as required;

               (v) neither the Company nor any of its subsidiaries is, or with
     the giving of notice or lapse of time or both would be, in violation of or
     in default under, its Restated Articles of Incorporation or By-Laws or any
     indenture, mortgage, deed of trust, loan agreement or other agreement or
     instrument known to such counsel to which the Company or any of its
     subsidiaries is a party or by which it or any of them or any of their
     respective properties is bound, except for violations and defaults which
     individually and in the aggregate are not material to the Company and its
     subsidiaries taken as a whole or to the holders of the Securities; the
     issue and sale of the Securities and the performance by the Company of its
     obligations under the Securities, the Indenture and this Agreement and the
     consummation of the transactions herein and therein contemplated will not
     conflict with or result in a breach of any of the terms or provisions of,
     or constitute a default under, any indenture, mortgage, deed of trust, loan
     agreement or other agreement or instrument known to such counsel to which
     the Company or any of its subsidiaries is a party or by which the Company

                                      -12-

     or any of its subsidiaries is bound or to which any of the property or
     assets of the Company or any of its subsidiaries is subject, nor will any
     such action result in any violation of the provisions of the Restated
     Articles of Incorporation or By-Laws of the Company or any applicable law
     or statute or any order, rule or regulation of any court or governmental
     agency or body having jurisdiction over the Company, its subsidiaries or
     any of their respective properties;

               (vi)   no consent, approval, authorization, order, license,
     registration or qualification of or with any court or governmental agency
     or body is required for the issue and sale of the Securities or the
     consummation of the other transactions contemplated by this Agreement or
     the Indenture, except such consents, approvals, authorizations, orders,
     licenses, registrations or qualifications as have been obtained under the
     Securities Act and the Trust Indenture Act and as may be required under
     state securities or Blue Sky laws in connection with the purchase and
     distribution of the Securities by the Underwriters or from the Pennsylvania
     Public Utility Commission and the Kentucky Public Service Commission in
     connection with the issuance and sale of the Securities;

               (vii)   such counsel (A) is of the opinion that each document
     incorporated by reference in the Registration Statement and the Prospectus
     as amended or supplemented (other than the financial statements and related
     schedules therein, as to which such counsel need express no opinion)
     complied as to form when filed with the Commission in all material respects
     with the Exchange Act, (B) believes that (except for the financial
     statements included therein as to which such counsel need express no
     belief) each part of the Registration Statement (including the documents
     incorporated by reference therein) filed with the Commission pursuant to
     the Securities Act, when such part became effective, did not and, as of the
     date such opinion is delivered, does not contain an untrue statement of a
     material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements therein not misleading, (C) is
     of the opinion that the Registration Statement and the Prospectus and any
     amendments and supplements thereto (except for the financial statements
     included therein as to which such counsel need express no opinion) comply
     as to form in all material respects with the requirements of the Securities
     Act and the Trust Indenture Act and (D) believes that (except for the
     financial statements included therein as to which such counsel need express
     no belief) the Registration Statement and the Prospectus, on the date of
     this Agreement, did not contain any untrue statement of a material fact or
     omit to state a material fact required to be stated therein or necessary to
     make the statements therein not misleading, and that the Prospectus as
     amended or supplemented, if applicable, does not contain any untrue
     statement of a material fact or omit to state a material fact necessary in
     order to make the statements therein, in the light of the circumstances
     under which they were made, not misleading;

               (viii)  the Company is not and, after giving effect to the
     offering and sale of the Securities, will not be an "investment company" or
     entity "controlled" by an "investment company", as such terms are defined
     in the Investment Company Act;

                                      -13-
<PAGE>
 
               (ix)  each of the Company and its subsidiaries owns, possesses or
     has obtained all licenses, permits, certificates, consents, orders,
     approvals and other authorizations from, and has made all declarations and
     filings with, all federal, state, local and other governmental authorities
     (including foreign regulatory agencies), all self-regulatory organizations
     and all courts and other tribunals, domestic or foreign, necessary to own
     or lease, as the case may be, and to operate its properties and to carry on
     its business as conducted as of the date hereof, except where the failure
     to so own or possess or to have so obtained or made would not, singly or in
     the aggregate, have a material adverse effect on the Company and its
     subsidiaries taken as a whole, and neither the Company nor any such
     subsidiary has received any actual notice of any proceeding relating to
     revocation or modification of any such license, permit, certificate,
     consent, order, approval or other authorization, except as described in the
     Registration Statement and the Prospectus; and each of the Company and its
     subsidiaries is in compliance with all laws and regulations relating to the
     conduct of its business as conducted as of the date of the Prospectus,
     except where the failure to be in compliance would not, singly or in the
     aggregate, have a material adverse effect on the Company and its
     subsidiaries taken as a whole;

               (x) the Company and its subsidiaries have good and marketable
     title in fee simple to all real property and good and marketable title to
     all personal property owned by them, in each case free and clear of all
     liens, encumbrances and defects except such as are described or referred to
     in the Prospectus or such as do not materially affect the value of such
     property and do not interfere with the use made and proposed to be made of
     such property by the Company and its subsidiaries; and any real property
     and buildings held under lease by the Company and its subsidiaries are held
     by them under valid, existing and enforceable leases with such exceptions
     as are not material and do not interfere with the use made or proposed to
     be made of such property and buildings by the Company or its subsidiaries;
     and

               (xi) each of the Company and its subsidiaries is in compliance
     with all Environmental Laws, except, in each case, where noncompliance,
     individually or in the aggregate, would not have a material adverse effect
     on the Company and its subsidiaries taken as a whole; and there are no
     legal or governmental proceedings pending or, to the knowledge of such
     counsel, threatened against or affecting the Company or any of its
     subsidiaries under any Environmental Law which, individually or in the
     aggregate, could reasonably be expected to have a material adverse effect
     on the Company and its subsidiaries taken as a whole.

          In rendering such opinions, such counsel may rely (A) as to matters
involving the application of laws other than the laws of the United States and
the Commonwealth of Pennsylvania, to the extent such counsel deems proper and to
the extent specified in such opinion, if at all, upon an opinion or opinions (in
form and substance reasonably satisfactory to Underwriters' counsel) of other
counsel reasonably acceptable to the Underwriters' counsel, familiar with the
applicable laws; (B) as to matters of fact, to the extent such counsel deems
proper, on certificates of responsible officers of the Company and certificates
or other written statements of officials of jurisdictions having custody of
documents respecting the corporate existence or good standing of the Company.
The opinion of such

                                      -14-
<PAGE>
 
counsel for the Company shall state that the opinion of any such other counsel
upon which he relied is in form satisfactory to such counsel and, in such
counsel's opinion, the Underwriters and he are justified in relying thereon.

          (g)  Reed Smith Shaw & McClay, counsel for the Company, shall have
furnished to you their written opinion, dated the Closing Date, in form and
substance satisfactory to you, to the effect that:

               (i)    the Company has been duly incorporated and is validly

     terms or provisions of, or constitute a default under, any indenture,
     mortgage, deed of trust, loan agreement or other agreement or instrument
     known to such counsel to which the Company or any of its subsidiaries is a
     party or by which the Company or any of its subsidiaries is bound or to
     which any of the property or assets of the Company or any of its
     subsidiaries is subject, nor will any such action result in any violation

     over the Company, its subsidiaries or any of their respective properties;

<PAGE>
 
               (vi)   no consent, approval, authorization, order, license,
     registration or qualification of or with any court or governmental agency
     or body is required for the issue and sale of the Securities or the

     the Indenture, except such consents, approvals, authorizations, orders,
     licenses, registrations or qualifications as have been obtained under the
     Securities Act and the Trust Indenture Act and as may be required under
     state securities or Blue Sky laws in connection with the purchase and
     distribution of the Securities by the Underwriters or from the Pennsylvania
     Public Utility Commission and the Kentucky Public Service Commission in
     connection with the issuance and sale of the Securities;

               (vii)    the statements in the Prospectus under "_______",

     Prospectus incorporated by reference from Item 3 of Part 1 of the Company's
     Annual Report on Form 10-K for the year ended December 31, 19___, in the
     Prospectus incorporated by reference from item 1 of Part II of the
     Company's Quarterly Reports on Form 10-Q, if any, filed with the Commission
     since such Annual Report, in the Prospectus incorporated by reference from
     item 5 of the Company's Current Reports on Form 8-K, if any, filed with the

     information called for with respect to such legal matters, documents or
     proceedings; and

               (viii)   such counsel (A) is of the opinion that the Registration
     Statement and the Prospectus and any amendments and supplements thereto
     (except for the financial statements included therein as to which such
     counsel need express no opinion) comply as to form in all material respects
     with the requirements of the Securities Act and the Trust Indenture Act and
     (B) believes that (except for the financial statements included therein as
     to which such counsel need express no belief) the Registration Statement
     and the Prospectus, on the date of this Agreement, did not contain any
     untrue statement of a material fact or omit to state a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading, and that the Prospectus as amended or supplemented, if
     applicable, does not contain any untrue statement of a material fact or
     omit to state a material fact necessary in order to make the statements
     therein, in the light of the circumstances under which they were made, not
     misleading;

          In rendering such opinions, such counsel may rely (A) as to matters
involving the application of laws other than the laws of the United States and
the Commonwealth of Pennsylvania, to the extent such counsel deems proper and to
the extent specified in such opinion, if at all, upon an opinion or opinions (in
form and substance reasonably satisfactory to Underwriters' counsel) of other
counsel reasonably acceptable to the Underwriters' counsel, familiar with the
applicable laws; (B) as to matters of fact, to the extent such counsel deems
proper, on certificates of responsible officers of the Company and certificates
or other written statements of officials of jurisdictions having custody of
documents respecting the corporate existence or good standing of the Company.
The opinion of such counsel for the Company shall state that the opinion of any
such other counsel upon which

                                      -16-
<PAGE>
 
they relied is in form satisfactory to such counsel and, in such counsel's
opinion, the Underwriters and they are justified in relying thereon.  With
respect to the matters to be covered in subparagraph (viii) above, counsel may
state their opinion and belief is based upon their participation in the
preparation of the Registration Statement and the Prospectus and any amendment
or supplement thereto (other than the documents incorporated by reference
therein) and review and discussion of the contents thereof (including the
documents incorporated by reference therein) but is without independent check or
verification except as specified.

          (h)  on the date hereof and on the Closing Date, Ernst & Young LLP
shall have furnished to you letters, dated such date, in form and substance
satisfactory to you, containing statements and information of the type
customarily included in accountants "comfort letters" to underwriters with
respect to the financial statements and certain financial information contained
in the Registration Statement and the Prospectus;

          (i)  you shall have received on and as of the Closing Date an opinion
of Kirkpatrick & Lockhart LLP, counsel to the Underwriters, with respect to the
validity of the Indenture and the Securities, the Registration Statement, the
Prospectus and other related matters as the Representatives may reasonably
request, and such counsel shall have received such papers and information as
they may reasonably request to enable them to pass upon such matters;

          [(j) the Securities shall have been approved for listing on the
[insert name of stock exchange], subject to official notice of issuance;] and

          (k) on or prior to the Closing Date, the Company shall have furnished
to the Representatives such further certificates and documents as the
Representatives shall reasonably request.

          7.  The Company agrees to indemnify and hold harmless each Underwriter
[, each affiliate of any Underwriter which assists such Underwriter in the
distribution of the Securities] and each person, if any, who controls any
Underwriter within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act, from and against any and all losses, claims,
damages and liabilities (including without limitation the legal fees and other
expenses incurred in connection with any suit, action or proceeding or any claim
asserted) caused by any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement or the Prospectus (as
amended or supplemented if the Company shall have furnished any amendments or
supplements thereto) or any preliminary prospectus, or caused by any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, except insofar as
such losses, claims, damages or liabilities are caused by any untrue statement
or omission or alleged untrue statement or omission made in reliance upon and in
conformity with information relating to any Underwriter furnished to the Company
in writing by such Underwriter through the Representatives expressly for use
therein.

          Each Underwriter agrees, severally and not jointly, to indemnify and
hold harmless the Company, its directors, its officers who sign the Registration
Statement and

                                      -17-
<PAGE>
 
each person who controls the Company within the meaning of Section 15 of the
Securities Act and Section 20 of the Exchange Act to the same extent as the
foregoing indemnity from the Company to each Underwriter, but only with
reference to information relating to such Underwriter furnished to the Company
in writing by such Underwriter through the Representatives expressly for use in
the Registration Statement, the Prospectus, any amendment or supplement thereto,
or any preliminary prospectus.

          If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any person in respect of which indemnity may be sought pursuant to either of the
two preceding paragraphs, such person (the "Indemnified Person") shall promptly
notify the person against whom such indemnity may be sought (the "Indemnifying
Person") in writing, and the Indemnifying Person, upon request of the
Indemnified Person, shall retain counsel reasonably satisfactory to the
Indemnified Person to represent the Indemnified Person and any others the
Indemnifying Person may designate in such proceeding and shall pay the fees and
expenses of such counsel related to such proceeding.  In any such proceeding,
any Indemnified Person shall have the right to retain its own counsel, but the
fees and expenses of such counsel shall be at the expense of such Indemnified
Person unless (i) the Indemnifying Person and the Indemnified Person shall have
mutually agreed to the contrary, (ii) the Indemnifying Person has failed within
a reasonable time to retain counsel reasonably satisfactory to the Indemnified
Person or (iii) the named parties in any such proceeding (including any
impleaded parties) include both the Indemnifying Person and the Indemnified
Person and representation of both parties by the same counsel would be
inappropriate due to actual or potential differing interests between them.  It
is understood that the Indemnifying Person shall not, in connection with any
proceeding or related proceeding in the same jurisdiction, be liable for the
fees and expenses of more than one separate firm (in addition to any local
counsel) for all Indemnified Persons, and that all such fees and expenses shall
be reimbursed as they are incurred.  Any such separate firm for the Underwriters
[, each affiliate of any Underwriter which assists such Underwriter in the
distribution of the Securities] and such control persons of Underwriters shall
be designated in writing by the first of the named Representatives on Schedule I
hereto and any such separate firm for the Company, its directors, its officers
who sign the Registration Statement and such control persons of the Company or
authorized representatives shall be designated in writing by the Company.  The
Indemnifying Person shall not be liable for any settlement of any proceeding
effected without its written consent, but if settled with such consent or if
there be a final judgment for the plaintiff, the Indemnifying Person agrees to
indemnify any Indemnified Person from and against any loss or liability by
reason of such settlement or judgment.  Notwithstanding the foregoing sentence,
if at any time an Indemnified Person shall have requested an Indemnifying Person
to reimburse the Indemnified Person for fees and expenses of counsel as
contemplated by the third sentence of this paragraph, the Indemnifying Person
agrees that it shall be liable for any settlement of any proceeding effected
without its written consent if (i) such settlement is entered into more than 30
days after receipt by such Indemnifying Person of the aforesaid request and (ii)
such Indemnifying Person shall not have reimbursed the Indemnified Person in
accordance with such request prior to the date of such settlement.  No
Indemnifying Person shall, without the prior written consent of the Indemnified
Person, effect any settlement of any pending or threatened proceeding in respect
of which any Indemnified Person is or could have been a party and indemnity
could have been sought

                                      -18-
<PAGE>
 
hereunder by such Indemnified Person, unless such settlement includes an
unconditional release of such Indemnified Person from all liability on claims
that are the subject matter of such proceeding.

          If the indemnification provided for in the first and second paragraphs
of this Section 7 is unavailable to an Indemnified Person or insufficient in
respect of any losses, claims, damages or liabilities referred to therein, then
each Indemnifying Person under such paragraph, in lieu of indemnifying such
Indemnified Person thereunder, shall contribute to the amount paid or payable by
such Indemnified Person as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company on the one hand and the Underwriters on the
other hand from the offering of the Securities 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 in connection with the statements or
omissions that resulted in such losses, claims, damages or liabilities, 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 shall be deemed
to be in the same respective proportions as the net proceeds from the offering
of such Securities (before deducting expenses) received by the Company and the
total underwriting discounts and the commissions received by the Underwriters
bear to the aggregate public offering price of the Securities.  The relative
fault of the Company on the one hand and the Underwriters on the other shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company or by the
Underwriters and the parties' relative intent, 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 contribution pursuant to this Section 7 were determined by pro rata
                                                                        --- ----
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in the immediately preceding paragraph.
The amount paid or payable by an Indemnified Person as a result of the losses,
claims, damages and liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses incurred by such Indemnified Person in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 7, in no event shall an
Underwriter be required to contribute any amount in excess of the amount by
which the total price at which the Securities underwritten by it and distributed
to the public were offered to the public exceeds the amount of any damages that
such Underwriter has otherwise been required to pay by reason of such 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
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.  The Underwriters' obligations to
contribute pursuant to this Section 7 are several in proportion to the
respective principal amounts of the Securities set forth opposite their names in
Schedule I hereto, and is not joint.

                                      -19-
<PAGE>
 
          The remedies provided for in this Section 7 are not exclusive and
shall not limit any rights or remedies which may otherwise be available to any
indemnified party at law or in equity.

          The indemnity and contribution agreements contained in this Section 7
and the representations and warranties of the Company set forth in this
Agreement shall remain operative and in full force and effect regardless of (i)
any termination of this Agreement, (ii) any investigation made by or on behalf
of any Underwriter or any person controlling any Underwriter or by or on behalf
of the Company, its officers or directors or any other person controlling the
Company and (iii) acceptance of and payment for any of the Securities.

          8.  Notwithstanding anything herein contained, this Agreement may be
terminated in the absolute discretion of the Representatives, by notice given to
the Company, if after the execution and delivery of this Agreement and prior to
the Closing Date (i) trading generally shall have been suspended or materially
limited on or by, as the case may be, any of the New York Stock Exchange, the
American Stock Exchange, the Philadelphia Stock Exchange, the National
Association of Securities Dealers, Inc., the Chicago Mercantile Exchange or the
Chicago Board of Trade, (ii) trading of any securities of or guaranteed by the
Company shall have been suspended on any exchange or in any over-the-counter
market, (iii) a general moratorium on commercial banking activities in New York
or in Pennsylvania shall have been declared by either Federal or the relevant
state authorities, or (iv) there shall have occurred any outbreak or escalation
of hostilities or any change in financial markets or any calamity or crisis
that, in the judgment of the Representatives, is material and adverse and which,
in the judgment of the Representatives, makes it impracticable to market the
Securities on the terms and in the manner contemplated in the Prospectus.

          9.  If on the Closing Date, any one or more of the Underwriters shall
fail or refuse to purchase Securities which it or they have agreed to purchase
under this Agreement, and the aggregate principal amount of Securities which
such defaulting Underwriter or Underwriters agreed but failed or refused to
purchase is not more than one-tenth of the aggregate principal amount of the
Securities, the other Underwriters shall be obligated severally in the
proportions that the principal amounts of Securities set forth opposite their
respective names in Schedule I hereto bears to the aggregate principal amount of
Securities set forth opposite the names of all such non-defaulting Underwriters,
or in such other proportions as the Representatives may specify, to purchase the
Securities which such defaulting Underwriter or Underwriters agreed but failed
or refused to purchase on such date; provided, that in no event shall the
                                     --------                            
principal amount of Securities that any Underwriter has agreed to purchase
pursuant to Section 1 be increased pursuant to this Section 9 by an amount in
excess of one-ninth of such principal amount of Securities without the written
consent of such Underwriter.  If, on the Closing Date, any Underwriter or
Underwriters shall fail or refuse to purchase Securities and the aggregate
principal amount of Securities with respect to which such default occurs is more
than one-tenth of the aggregate principal amount of Securities to be purchased,
and arrangements satisfactory to you and the Company for the purchase of such
Securities are not made within 36 hours after such default, this Agreement shall
terminate without liability on the part of any non-defaulting Underwriter or the
Company.  In any such case either you or the Company shall have the right to
postpone the Closing Date, but in no event for longer than seven days, in order
that the required

                                      -20-
<PAGE>
 
changes, if any, in the Registration Statement and in the Prospectus or in any
other documents or arrangements may be effected.  Any action taken under this
paragraph shall not relieve any defaulting Underwriter from liability in respect
of any default of such Underwriter under this Agreement.

          10.  If this Agreement shall be terminated by the Underwriters, or any
of them, because of any failure or refusal on the part of the Company to comply
with the terms or to fulfill any of the conditions of this Agreement, or if for
any reason the Company shall be unable to perform its obligations under this
Agreement or any condition of the Underwriters' obligations cannot be fulfilled,
the Company agrees to reimburse the Underwriters or such Underwriters as have so
terminated this Agreement with respect to themselves, severally, for all out-of-
pocket expenses (including the fees and expenses of their counsel) reasonably
incurred by such Underwriters in connection with this Agreement or the offering
of Securities.

          11.  This Agreement shall inure to the benefit of and be binding upon
the Company, the Underwriters, [each affiliate of any Underwriter which assists
such Underwriter in the distribution of the Securities,] any controlling persons
referred to herein and their respective successors and assigns.  Nothing
expressed or mentioned in this Agreement is intended or shall be construed to
give any other person, firm or corporation any legal or equitable right, remedy
or claim under or in respect of this Agreement or any provision herein
contained.  No purchaser of Securities from any Underwriter shall be deemed to
be a successor by reason merely of such purchase.

          12.  Any action by the Underwriters hereunder may be taken by you
jointly or by the first of the named Representatives set forth in Schedule I
hereto alone on behalf of the Underwriters, and any such action taken by you
jointly or by the first of the named Representatives set forth in Schedule I
hereto alone shall be binding upon the Underwriters.  All notices and other
communications hereunder shall be in writing and shall be deemed to have been
duly given if mailed or transmitted by any standard form of telecommunication.
Notices to the Underwriters shall be given at the address set forth in Schedule
I hereto.  Notices to the Company shall be given to it at 420 Boulevard of the
Allies, Pittsburgh, Pennsylvania 15219, Attention: Jeffrey C. Swoveland,
Treasurer (telefax number:  412-553-5875).

          13.  This Agreement may be signed in counterparts, each of which shall
be an original and all of which together shall constitute one and the same
instrument.

          14.  This Agreement shall be governed by and construed in accordance
with the laws of the State of New York, without giving effect to the conflicts
of laws provisions thereof.

                                    Very truly yours,

Dear Sirs:

          Equitable Resources, Inc., a Pennsylvania corporation (the "Company"),
confirms its agreement with each of you with respect to the issue and sale from
time to time by the Company of its Medium-Term Notes, Series     due from 9
                                                             ---
months to [30] years from date of issue (the "Securities") in an aggregate
initial offering price of up to $           (or the equivalent thereof in one or
                                 ----------
more foreign currencies or composite currencies) [, as such amount shall be
reduced by the aggregate initial offering price of any other debt securities
issued by the Company, whether within or without the United States ("Other
Securities") pursuant to the registration statement referred to below,] and
agrees with each of you (individually, an "Agent", and collectively, the
"Agents", which term shall include any additional agents appointed pursuant to
Section 13 hereof) as set forth in this Agreement.  The Securities will be
issued under an indenture dated as of June    , 1996 (the "Indenture") between
                                           ---
the Company and Bank of Montreal Trust Company, a           , as trustee (the
                                                  ----------
"Trustee").  The Securities shall have the maturities, interest rates,
redemption provisions, if any, and other terms set forth in the Prospectus
referred to below as it may be amended or supplemented from time to time.  The
Securities will be issued, and the terms and rights thereof established, from
time to time by the Company in accordance with the Indenture.

          On the basis of the representations and warranties herein contained,
but subject to the terms and conditions stated herein and to the reservation by
the Company of the right to sell Securities directly to investors (other than
broker-dealers) on its own behalf, the Company hereby (i) appoints the Agents as
the exclusive agents of the Company for the purpose of soliciting and receiving
offers to purchase Securities from the Company by others pursuant to Section
2(a)
<PAGE>
 
hereof and (ii) agrees that, except as otherwise contemplated herein, whenever
it determines to sell Securities directly to any Agent as principal, it will
enter into a separate agreement (each such agreement a "Terms Agreement"),
substantially in the form of Exhibit A hereto, relating to such sale in
accordance with Section 2(b) hereof.

          The Company has prepared and filed two registration statements on Form
S-3 (Nos. 33-53,703 and 33-00,000) in respect of the Securities with the
Securities and Exchange Commission (the "Commission") in accordance with the
provisions of the Securities Act of 1933, as amended, and the rules and
regulations of the Commission thereunder (collectively, the "Securities Act").
The Company also has filed with, or proposes to file with, the Commission
pursuant to Rule 424 under the Securities Act supplements to the prospectus
included in those registration statements as of the date hereof that will
describe certain terms of the Securities.  Those registration statements,
including the exhibits thereto, as amended to the Commencement Date (as
hereinafter defined) are hereinafter referred to as the "Registration Statement"
and the prospectus in the form in which it appears in the Registration Statement
as of the date hereof is hereinafter referred to as the "Basic Prospectus".  The
Basic Prospectus as supplemented by the prospectus supplement or supplements
(each, a "Prospectus Supplement") specifically relating to the Securities in the
form filed with, or transmitted for filing to, the Commission pursuant to Rule
424 under the Securities Act is hereinafter referred to as the "Prospectus".
Any reference in this Agreement to the Registration Statement, the Basic
Prospectus, any preliminary form of the Prospectus (a "preliminary prospectus")
previously filed with the Commission pursuant to Rule 424 or the Prospectus
shall be deemed to refer to and include the documents incorporated by reference
therein pursuant to Item 12 of Form S-3 under the Securities Act which were
filed under the Securities Exchange Act of 1934, as amended, and the rules and
regulations of the Commission thereunder (collectively, the "Exchange Act") on
or before the date of this Agreement or the date of the Basic Prospectus, any
preliminary prospectus or the Prospectus, as the case may be; and any reference
to "amend", "amendment" or "supplement" with respect to the Registration
Statement, the Basic Prospectus, any preliminary prospectus or the Prospectus,
including any supplement to the Prospectus that sets forth only the terms of a
particular issue of the Securities (a "Pricing Supplement"), shall be deemed to
refer to and include any documents filed under the Exchange Act after the date
of this Agreement, or the date of the Basic Prospectus, any preliminary
prospectus or the Prospectus, as the case may be, which are deemed to be
incorporated by reference therein.

          1.  Representations.  The Company represents and warrants to, and
agrees with, each Agent as of the Commencement Date, as of each date on which
the Company accepts an offer to purchase Securities (including any purchase by
an Agent as principal pursuant to a Terms Agreement or otherwise), as of each
date the Company issues and sells Securities and as of each date the
Registration Statement or the Basic Prospectus is amended or supplemented, as
follows (it being understood that such representations and warranties shall be
deemed to relate to the Registration Statement, the Basic Prospectus and the
Prospectus, each as amended or supplemented to each such date):

          (a) The Registration Statement has been declared effective by the
     Commission under the Securities Act; no stop order suspending the
     effectiveness of the Registration Statement has been issued and no
     proceeding for that purpose has been instituted or, to the knowledge of the
     Company, threatened by the Commission; and the Registration Statement and
     Prospectus (as amended or supplemented if the Company shall have

                                      -2-
<PAGE>
 
     furnished any amendments or supplements thereto) comply, or will comply, as
     the case may be, in all material respects with the Securities Act and the
     Trust Indenture Act of 1939, as amended, and the rules and regulations of
     the Commission thereunder (collectively, the "Trust Indenture Act"), and do
     not and will not, as of the applicable effective date as to the
     Registration Statement and any amendment thereto and as of the date of the
     Prospectus and any amendment or supplement thereto, contain 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, in the light
     of the circumstances under which they were made, not misleading; except
     that the foregoing representations and warranties shall not apply to (i)
     statements or omissions in the Registration Statement or the Prospectus
     made in reliance upon and in conformity with information relating to any
     Agent furnished to the Company in writing by such Agent expressly for use
     therein, and (ii) that part of the Registration Statement which constitutes
     the Statement of Eligibility and Qualification (Form T-1) under the Trust
     Indenture Act of the Trustee;

          (b) The documents incorporated by reference in the Prospectus, when
     they became effective or were filed with the Commission, as the case may
     be, conformed in all material respects to the requirements of the
     Securities Act or the Exchange Act, as applicable, and none of such
     documents contained an untrue statement of a material fact or omitted to
     state a material fact required to be stated therein or necessary to make
     the statements therein, in the light of the circumstances under which they
     were made, not misleading; and any further documents so filed and
     incorporated by reference in the Prospectus, or any further amendment or
     supplement thereto, when such documents become effective or are filed with
     the Commission, as the case may be, will conform in all material respects
     to the requirements of the Securities Act or the Exchange Act, as
     applicable, and will not contain an untrue statement of a material fact or
     omit to state a material fact required to be stated therein or necessary to
     make the statements therein, in the light of the circumstances under which
     they are made, not misleading;

          (c) The financial statements, and the related notes thereto, included
     or incorporated by reference in the Registration Statement and the
     Prospectus present fairly the consolidated financial position of the
     Company and its consolidated subsidiaries as of the dates indicated and the
     results of their operations and the changes in their consolidated cash
     flows for the periods specified; said financial statements have been
     prepared in conformity with generally accepted accounting principles
     applied on a consistent basis, and the supporting schedules included or
     incorporated by reference in the Registration Statement present fairly the
     information required to be stated therein[; and the pro forma financial
     information, and the related notes thereto, if any, included or
     incorporated by reference in the Registration Statement and the Prospectus
     has been prepared in accordance with the applicable requirements of the
     Securities Act and the Exchange Act, as applicable, and is based upon good
     faith estimates and assumptions believed by the Company to be reasonable];

          (d) Since the respective dates as of which information is given in the
     Registration Statement and the Prospectus, there has not been any change in
     the capital stock or long-term debt of the Company or any of its
     subsidiaries other than pursuant to the conversion of convertible
     securities or the exercise of stock options, in either case, set forth in
     the most recent financial statements of the Company included or
     incorporated in

     involving a prospective material adverse change, in or affecting the
     general affairs, business, prospects, management, financial position,
     stockholders' equity or results of operations of the Company and its
     subsidiaries, taken as a whole, otherwise than as set forth or contemplated
     in the Prospectus; and except as set forth or contemplated in the
     Prospectus neither the Company nor any of its subsidiaries has entered into
     any transaction or agreement (whether or not in the ordinary course of
     business) material to the Company and its subsidiaries taken as a whole;

          (e) The Company has been duly incorporated and is validly existing as
     a corporation in good standing under the laws of its jurisdiction of
     incorporation, with power and authority (corporate and other) to own its
     properties and conduct its business as described in the Prospectus, and has
     been duly qualified as a foreign corporation for the transaction of
     business and is in good standing under the laws of each other jurisdiction
     in which it owns or leases properties, or conducts any business, so as to

     or in good standing would not have a material adverse effect on the Company
     and its subsidiaries taken as a whole;

          (f) Each of the Company's subsidiaries has been duly incorporated and

     performance by the Company of all of its obligations under the Securities,
     the Indenture, this Agreement and any Terms Agreement and the consummation

     prospects, management, consolidated financial position, stockholders'
     equity or results of operations of the Company and its subsidiaries taken

     property and do not interfere with the use made or proposed to be made of
     such property by the Company and its subsidiaries; and any real property
     and buildings held under lease by the Company and its subsidiaries are held

     regulatory organizations and all courts and other tribunals, domestic or
     foreign, necessary to own or lease, as the case may be, and to operate its
     properties and to carry on its business as conducted as of the date hereof,
     except where the failure to so own or possess or to have so obtained or
     made would not, singly or in the aggregate, have a material adverse effect
     on the Company and its subsidiaries taken as a whole, and neither the
     Company nor any such subsidiary has received any actual notice of any
     proceeding relating to revocation or modification of any such license,
     permit, certificate, consent, order, approval or other authorization,
     except as described in the Registration Statement and the Prospectus; and
     each of the Company and its subsidiaries is in compliance with all laws and
     regulations relating to the conduct of its business as conducted as of the
     date hereof, except where the failure to be in compliance would not, singly
     or in the aggregate, have a material adverse effect on the Company and its
     subsidiaries taken as a whole;

          (r) The Company and its subsidiaries (i) are in compliance with any
     and all applicable foreign, federal, state and local laws and regulations
     relating to the protection of human health and safety, the environment or
     hazardous or toxic substances or wastes, pollutants or contaminants
     ("Environmental Laws"), (ii) have received all permits, licenses or other
     approvals required of them under applicable Environmental Laws to conduct
     their respective businesses, (iii) are in compliance with all terms and
     conditions of any such permit, license or approval, except where such
     noncompliance with Environmental Laws, failure to receive required permits,
     licenses or other approvals or failure to comply with the terms and
     conditions of such permits, licenses or approvals would not, singly or in
     the aggregate, have a material adverse effect on the Company and its
     subsidiaries, taken as a whole, and (iv) are not aware of any
     administrative or judicial action being contemplated by governmental
     authorities relating to Environmental Laws; neither the Company nor any of
     its subsidiaries are subject to any consent decree or compliance or
     administrative order issued pursuant to, or are the subject of any pending
     investigation or litigation under, applicable Environmental Laws except for
     such actions, decrees, orders or investigations which do not and are not
     reasonably expected to have a material adverse effect on, or cause material
     changes to, the general affairs, business, prospects, management, financial
     position, stockholders' equity or results of operations of the Company and
     its subsidiaries, taken as a whole; and neither the Company nor any of its
     subsidiaries is a party to a governmental proceeding arising under any
     Environmental Law which involves potential monetary sanctions, exclusive of
     interest and costs, of $100,000 or more;

          (s) In the ordinary course of its business, the Company reviews the
     effect of Environmental Laws on the business, operations and properties of
     the Company and its subsidiaries, in the course of which it identifies and
     evaluates associated costs and liabilities (including, without limitation,
     any capital or operating expenditures required for clean-up, closure of
     properties or compliance with Environmental Laws or any permit, license or
     approval, any related constraints on operating activities and any potential
     liabilities to third parties); and, on the basis of such review, the
     Company has reasonably concluded that such associated costs and liabilities
     would not, singly or in the aggregate, have a material adverse effect on
     the Company and its subsidiaries, taken as a whole;

                                      -7-

          (t) There are no existing or, to the best knowledge of the Company,
     threatened labor disputes with the employees of the Company or any of its
     subsidiaries which are likely to have a material adverse effect on the
     Company and its subsidiaries taken as a whole;

          (u) Each employee benefit plan, within the meaning of Section 3(3) of
     the Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
     that is maintained, administered or contributed to by the Company or any of
     its affiliates for employees or former employees of the Company and its
     affiliates has been maintained in compliance with its terms and the
     requirements of any applicable statutes, orders, rules and regulations,
     including but not limited to ERISA and the Internal Revenue Code of 1986,
     as amended (the "Code").  No prohibited transaction, within the meaning of
     Section 406 of ERISA or Section 4975 of the Code has occurred with respect
     to any such plan excluding transactions effected pursuant to a statutory or
     administrative exemption.  For each such plan which is subject to the
     funding rules of Section 412 of the Code or Section 302 of ERISA no
     "accumulated funding deficiency" as defined in Section 412 of the Code has
     been incurred, whether or not waived, and the fair market value of the
     assets of each such plan (excluding for these purposes accrued but unpaid
     contributions) exceeded the present value of all benefits accrued under
     such plan determined using reasonable actuarial assumptions; and

          (v) Immediately after any sale of Securities by the Company hereunder
     or under any applicable Terms Agreement, the aggregate amount of Securities
     that will have been issued and sold by the Company hereunder or under any
     Terms Agreement and of any debt securities of the Company (other than the
     Securities) that will have been issued and sold pursuant to the
     Registration Statement will not exceed the amount of debt securities
     registered under the Registration Statement.

          2.   Solicitations as Agent; Purchases as Principal.

          (a) Solicitations as Agent.  On the basis of the representations and
     warranties herein contained, but subject to the terms and conditions herein
     set forth, each of the Agents hereby severally and not jointly agrees, as
     agent of the Company, to use its reasonable efforts to solicit offers to
     purchase Securities from the Company upon the terms and conditions set
     forth in the Prospectus as amended or supplemented from time to time.  So
     long as this Agreement remains in effect with respect to any Agent, the
     Company shall not, without the consent of such Agent, solicit or accept
     offers to purchase, or sell, Securities or any other debt securities with a
     maturity at the time of original issuance of 9 months to [30] years except
     pursuant to this Agreement and any Terms Agreement or except pursuant to a
     private placement not constituting a public offering under the Securities
     Act or except in connection with a firm commitment underwriting pursuant to
     an underwriting agreement that does not provide for a continuous offering
     of medium-term debt securities.  However, the Company reserves the right to
     sell, and may solicit and accept offers to purchase, Securities directly on
     its own behalf to investors (other than broker-dealers).

               The Company reserves the right, in its sole discretion, to
     instruct the Agents to suspend at any time, for any period of time or
     permanently, the solicitation of

                                      -8-
<PAGE>
 
     offers to purchase Securities.  Upon receipt of at least one business day's
     prior notice from the Company, each Agent will suspend solicitation of
     offers to purchase Securities from the Company until such time as the
     Company has advised such Agent or Agents that such solicitation may be
     resumed.  During the period of time that such solicitation is suspended,
     the Company shall not be required to deliver any opinions, letters or
     certificates in accordance with Sections 4(i), 4(j) and 4(k) hereof;
     provided, that if the Registration Statement or Prospectus is amended or
     supplemented during the period of suspension (other than by an amendment or
     supplement providing solely for a change in the interest rates, redemption
     provisions, amortization schedules or maturities offered for Securities or
     for a change that the Agents deem to be immaterial), no Agent shall be
     required to resume soliciting offers to purchase Securities until the
     Company has delivered such opinions, letters and certificates in accordance
     with Sections 4(i), 4(j) and 4(k) hereof as such Agent may reasonably
     request.

               The Company agrees to pay each Agent, as consideration for the
     sale of each Security resulting from a solicitation made or an offer to
     purchase received by such Agent, a commission in the form of a discount
     from the purchase price of such Security in an amount equal to the
     following applicable percentage of the principal amount of such Security
     sold:

</TABLE>

               The Agents are authorized to solicit offers to purchase
     Securities only in the principal amount of $                   (or, in the
                                                 ------------------
     case of Securities not denominated in U.S. dollars, the equivalent thereof
     in the applicable foreign currency or composite currency, rounded down to
     the nearest 1,000 units of such foreign currency or composite currency) or
     any amount in excess thereof which is an integral multiple of
     $                (or, in the case of Securities not denominated in U.S.
      ---------------
     dollars, 1,000 units of such foreign currency or composite currency).  Each
     Agent shall communicate to the Company, orally or in writing, each offer to
     purchase Securities received by such Agent as agent that in its judgment
     should be considered by the Company.  The Company shall have the sole right
     to accept offers to purchase Securities and may reject any such offer in
     whole or in part.  Each Agent shall have the right, in its

                                      -9-
<PAGE>
 
     sole discretion, to reject any offer to purchase Securities, in whole or in
     part, that it considers to be unacceptable and any such rejection shall not
     be deemed a breach of its agreements herein contained.  The procedural
     details relating to the issue and delivery of Securities sold by an Agent
     as agent and the payment therefor are set forth in the Administrative
     Procedures (as hereinafter defined).

          (b) Purchase as Principal.  Each sale of Securities to any Agent as
     principal shall be made in accordance with the terms of this Agreement and
     (unless such Agent shall otherwise agree) a Terms Agreement which will
     provide for the sale of such Securities to, and the purchase thereof by,
     such Agent.  A Terms Agreement will be substantially in the form of Exhibit
     A hereto but may take the form of an exchange of any standard form of
     written telecommunication between an Agent and the Company and may also
     specify certain provisions relating to the reoffering of such Securities by
     such Agent.  The commitment of any Agent to purchase Securities as
     principal, whether pursuant to any Terms Agreement or otherwise, shall be
     deemed to have been made on the basis of the representations and warranties
     of the Company herein contained and shall be subject to the terms and
     conditions set forth herein and in the applicable Terms Agreement.  Each
     agreement by an Agent to purchase Securities as principal (pursuant to a
     Terms Agreement or otherwise) shall specify the principal amount of
     Securities to be purchased by such Agent pursuant thereto, the price to be
     paid to the Company for such Securities, the maturity date of such
     Securities, the interest rate or interest rate basis, if any, applicable to
     such Securities, any other terms of such Securities, the time and date and
     place of delivery of and payment for such Securities (the time and date of
     any and each such delivery and payment, being a "Time of Delivery"), any
     provisions relating to rights of, and default by, underwriters acting
     together with such Agent in the reoffering of Securities, and shall also
     specify any requirements for opinions of counsel, accountants' letters and
     officers' certificates pursuant to Section 4 hereof.  Unless otherwise
     specified in a Terms Agreement, the procedural details relating to the
     issue and delivery of Securities purchased by an Agent as principal and the
     payment therefor shall be set forth in the Administrative Procedures.

          (c) Obligations Several.  The Company acknowledges that the
     obligations of the Agents are several and not joint and, subject to the
     provisions of this Section 2, each Agent shall have complete discretion as
     to the manner in which it solicits purchasers for the Securities and as to
     the identity thereof.

          (d) Administrative Procedures.  The Agents and the Company agree to
     perform their respective duties and obligations specifically provided to be
     performed in the Medium-Term Notes Administrative Procedures (the
     "Administrative Procedures") attached hereto as Exhibit B, as the same may
     be amended from time to time.  The Administrative Procedures may be amended
     only by written agreement of the Company and the Agents.

          [(e)  Other Securities.  The Company agrees to notify each Agent of
     sales by the Company of Other Securities.]

          3.   Commencement Date.  The documents required to be delivered
pursuant to Section 6 hereof on the Commencement Date shall be delivered to the
Agents at the offices of

postponed by agreement between the Agents and the Company but in no event shall
be later than the day prior to the earlier of the date on which solicitation of
offers to purchase Securities is commenced or the first date on which the
Company accepts an offer by any Agent to purchase Securities as principal (such
time and date being referred to herein as the "Commencement Date").

          4.   Covenants of the Company.  The Company covenants and agrees with
each Agent:

          (a)(i) To make no amendment or supplement to the Registration
     Statement or the Prospectus prior to the termination of the offering of the
     Securities pursuant to this Agreement or any Terms Agreement which shall be
     disapproved by any Agent after reasonable opportunity to comment thereon;
     provided, however, that the foregoing shall not apply to any of the
     Company's periodic filings with the Commission described in subsection
     (iii) below, copies of which filings the Company will cause to be delivered
     to the Agents promptly after their transmission to the Commission for
     filing; (ii), subject to the foregoing clause (i), promptly to cause each
     Prospectus Supplement to be filed with or transmitted for filing to the
     Commission in accordance with Rule 424(b) under the Securities Act and to
     prepare, with respect to any Securities to be sold through or to any Agent

     Securities in a form previously approved by such Agent and to file such
     Pricing Supplement in accordance with Rule 424(b) under the Securities Act;
     and (iii) promptly to file all reports and any definitive proxy or
     information statements required to be filed by the Company with the

     Act for so long as the delivery of a prospectus is required in connection
     with the offering or sale of Securities.  To advise each Agent (i) of the
     filing of any amendment or supplement to the Basic Prospectus or any
     amendment to the Registration Statement and of the effectiveness of any
     such amendment to the Registration Statement, (ii) of the issuance by the
     Commission of any stop order suspending the effectiveness of the
     Registration Statement or any order preventing or suspending the use of any
     prospectus relating to the Securities or the initiation or threatening of
     any proceeding for that purpose, or of any request by the Commission for
     any amendment or supplement of the Registration Statement or Prospectus or
     for additional information; and (iii) of the receipt by the Company of any
     notification with respect to any suspension of the qualification of the
     Securities for offering or sale in any jurisdiction or of the initiation or
     threatening of any proceeding for any such purpose.  To use its best
     efforts to prevent the issuance of any such stop order or of any such order
     preventing or suspending the use of any such prospectus or of any
     notification suspending any such qualification and, if issued, to use
     promptly its best efforts to obtain withdrawal thereof as soon as possible.
     If the Basic Prospectus is amended or supplemented as a result of the
     filing under the Exchange Act of any document incorporated by reference in
     the Prospectus, no Agent shall be obligated to solicit offers to purchase
     Securities so long as it is not reasonably satisfied with such document.

          (b) To endeavor to qualify the Securities for offer and sale under the
     securities or Blue Sky laws of such jurisdictions as the Agents shall
     reasonably request and to continue such qualification in effect so long as
     reasonably required in connection with the

                                      -11-
<PAGE>
 
     distribution of the Securities and to pay all fees and expenses (including
     fees and disbursements of counsel to the Agents) reasonably incurred in
     connection with such qualification and in connection with the determination
     of the eligibility of the Securities for investment under the laws of such
     jurisdictions as any Agent may designate; provided, that the Company shall
     not be required to file a general consent to service of process or qualify
     to do business in any jurisdiction.

          (c) To furnish each Agent and counsel to the Agents, at the expense of
     the Company, a signed copy of the Registration Statement (as originally
     filed) and each amendment thereto, in each case including exhibits and
     documents incorporated by reference therein and, during the period
     mentioned in paragraph (d) below, to furnish each Agent as many copies of
     the Prospectus (including all amendments and supplements thereto) and
     documents incorporated by reference therein as such Agent may reasonably
     request.

          (d) If at any time when a prospectus relating to the Securities is
     required to be delivered under the Securities Act, any event shall occur as
     a result of which the Prospectus, as then amended or supplemented, would
     include an 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 such Prospectus is delivered to a
     purchaser, not misleading, or, if in the opinion of the Agents or the
     Company, it is necessary at any time to amend or supplement the Prospectus
     to comply with law, to immediately notify the Agents by telephone (with
     confirmation in writing) and request each Agent (i) in its capacity as
     agent of the Company, to suspend solicitation of offers to purchase
     Securities from the Company (and, if so notified, such Agent shall cease
     such solicitations and cease using the Prospectus as soon as practicable,
     but in any event not later than one business day later); and (ii) to cease
     sales of any Securities such Agent may then own as principal.  If the
     Company shall decide to amend or supplement the Registration Statement or
     the Prospectus, as then amended or supplemented, to so advise each Agent
     promptly by telephone (with confirmation in writing) and, at its expense,
     to prepare and cause to be filed promptly with the Commission an amendment
     or supplement to the Registration Statement or the Prospectus, as then
     amended or supplemented, satisfactory in all respects to the Agents, that
     will correct such statement or omission or effect such compliance and to
     supply such amended or supplemented Prospectus to the Agents in such
     quantities as they may reasonably request.  If any such amendment or
     supplement and any documents, opinions, letters and certificates furnished
     to the Agents pursuant to Sections 4(e), 4(i), 4(j) and 4(k) hereof in
     connection with the preparation and filing of such amendment or supplement
     are satisfactory in all respects to the Agents, upon the filing with the
     Commission of such amendment or supplement to the Prospectus or upon the
     effectiveness of an amendment to the Registration Statement, the Agents
     shall resume the solicitation of offers to purchase Securities hereunder.
     Notwithstanding any other provision of this Section 4(d), until the
     distribution of any Securities any Agent may own as principal has been
     completed or in the event such Agent, in the opinion of its counsel, is
     otherwise required to deliver a prospectus in respect of a transaction in
     the Securities, if any event described in this Section 4(d) occurs the
     Company shall, at its own expense, promptly prepare and file with the
     Commission an amendment or supplement, satisfactory in all respects to such
     Agent, that will correct such statement or omission or effect such
     compliance, shall supply such amended or supplemented

                                      -12-
<PAGE>
 
     Prospectus to such Agent in such quantities as such Agent may reasonably
     request and shall furnish to such Agent pursuant to Sections 4(e), 4(i),
     4(j) and 4(k) hereof such documents, certificates, opinions and letters as
     it may request in connection with the preparation and filing of such
     amendment or supplement.

          (e) To furnish to the Agents during the term of this Agreement such
     relevant documents and certificates of officers of the Company relating to
     the business, operations and affairs of the Company, the Registration
     Statement, the Basic Prospectus, any amendments or supplements thereto, the
     Indenture, the Securities, this Agreement, the Administrative Procedures,
     any applicable Terms Agreement and the performance by the Company of its
     obligations hereunder or thereunder as the Agents may from time to time
     reasonably request and to notify the Agents promptly in writing of any
     downgrading, or upon its receipt of any notice of (i) any intended or
     potential downgrading or (ii) any review or possible change that does not
     indicate an improvement in the rating accorded any securities of, or
     guaranteed by, the Company by any "nationally recognized statistical rating
     organization," as such term is defined for purposes of Rule 436(g)(2) under
     the Securities Act.

          (f) To make generally available to its security holders and to each
     Agent as soon as practicable earnings statements which satisfy the
     provisions of Section 11(a) of the Securities Act and Rule 158 of the
     Commission promulgated thereunder covering periods of at least twelve
     months beginning in each case with the first fiscal quarter of the Company
     occurring after the "effective date" (as defined in Rule 158) of the
     Registration Statement with respect to each sale of Securities.

          (g) Until the expiration of the fifth anniversary of the last sale of
     Securities in accordance with this Agreement, to furnish to each Agent
     copies of all reports or other communications (financial or other)
     furnished to holders of Securities and copies of any reports and financial
     statements furnished to or filed with the Commission or any national
     securities exchange.

          (h) From the date of any applicable Terms Agreement with an Agent or
     other agreement by such Agent to purchase Securities as principal and
     continuing to and including the business day following the related Time of
     Delivery, not to offer, sell, contract to sell or otherwise dispose of any
     debt securities of or guaranteed by the Company which are substantially
     similar to such Securities, without the prior written consent of such
     Agent.

          (i) Each time the Registration Statement or the Prospectus is amended
     or supplemented (other than by an amendment or supplement providing solely
     for a change in the interest rates, redemption provisions, amortization
     schedules or maturities offered on Securities or for a change the Agents
     deem to be immaterial) and each time the Company sells Securities to an
     Agent as principal pursuant to a Terms Agreement or other agreement and
     such Terms Agreement or other agreement requires the delivery of opinions
     under this Section 4(i) as a condition to the purchase of such Securities
     pursuant to such Terms Agreement or other agreement, to furnish or cause to
     be furnished forthwith to such Agent written opinions of the Chief Legal
     Officer of the Company and of Reed Smith Shaw & McClay or other counsel for
     the Company satisfactory to such

                                      -13-
<PAGE>
 
     Agent, dated the date of such amendment or supplement or the related Time
     of Delivery relating to such sale, as the case may be, in form satisfactory
     to such Agent, of the same tenor as the opinions referred to in Sections
     6(b) and 6(c) hereof but modified to relate to the Registration Statement
     and the Prospectus as amended and supplemented to the date of such
     opinions, or, in lieu of such opinions, counsel last furnishing such
     opinions may furnish to such Agent letters to the effect that such Agent
     may rely on the opinions of such counsel which were last furnished to such
     Agent to the same extent as though they were dated the date of such letters
     (except that the statements in such last opinions shall be deemed to relate
     to the Registration Statement and the Prospectus as amended or supplemented
     to the date of delivery of such letters).

          (j) Each time the Registration Statement or the Prospectus is amended
     or supplemented to include or incorporate amended or supplemented financial
     information and each time the Company sells Securities to such Agent as
     principal pursuant to a Terms Agreement or other agreement and such Terms
     Agreement or other agreement requires the delivery of a letter under this
     Section 4(j) as a condition to the purchase of Securities pursuant to such
     Terms Agreement or other agreement, to cause the independent certified
     public accountants who have certified the financial statements of the
     Company and its subsidiaries included or incorporated by reference in the
     Registration Statement forthwith to furnish such Agent a letter, dated the
     date of such amendment or supplement or the related Time of Delivery
     relating to such sale, as the case may be, in form satisfactory to such
     Agent, of the same tenor as the letter referred to in Section 6(e) hereof
     but modified to relate to the Registration Statement and the Prospectus as
     amended or supplemented to the date of such letter with such changes as may
     be necessary to reflect such amended or supplemented financial information
     included or incorporated by reference in the Registration Statement or the
     Prospectus as amended or supplemented; provided, however, that, with
     respect to any financial information or other matter, such letter may
     reconfirm as true and correct at such date, as though made at and as of
     such date, rather than repeat, statements with respect to such financial
     information or other matter made in the letter referred to in Section 6(e)
     hereof which was last furnished to such Agent.

          (k) Each time the Registration Statement or the Prospectus is amended
     or supplemented (other than by an amendment or supplement providing solely
     for a change in the interest rates, redemption provisions, amortization
     schedules or maturities offered on Securities or for a change the Agents
     deem to be immaterial), and each time the Company sells Securities to such
     Agent as principal pursuant to a Terms Agreement or other agreement and
     such Terms Agreement or other agreement requires the delivery of a
     certificate under this Section 4(k) as a condition to the purchase of
     Securities pursuant to such Terms Agreement or other agreement, to furnish
     or cause to be furnished forthwith to such Agent a certificate signed by an
     executive officer of the Company, dated the date of such amendment or
     supplement or the related Time of Delivery relating to such sale, as the
     case may be, in form satisfactory to such Agent, of the same tenor as the
     certificate referred to in Section 6(f) hereof but modified to relate to
     the Registration Statement and the Prospectus as amended and supplemented
     to the date of delivery of such certificate or to the effect that the
     statements contained in the certificate referred to in Section 6(f) hereof
     which was last furnished to such Agent are true and correct at such date as
     though

                                      -14-
<PAGE>
 
     made at and as of such date (except that such statements shall be deemed to
     relate to the Registration Statement and the Prospectus as amended or
     supplemented to such date).

          5.   Costs and Expenses.  The Company covenants and agrees with each
Agent that the Company will, whether or not any sale of Securities is
consummated, pay or cause to be paid all costs and expenses incident to the
performance of its obligations hereunder and under any applicable Terms
Agreement, including without limiting the generality of the foregoing, all costs
and expenses (i) incident to the preparation, issuance, execution,
authentication and delivery of the Securities, (ii) incident to the preparation,
printing and filing under the Securities Act of the Registration Statement, the
Prospectus and any preliminary prospectus (including in each case all exhibits,

agencies in connection with the rating of the Securities, (viii) the fees and
disbursements of the Company's counsel and accountants and of the Trustee and

out-of-pocket expenses incurred by the Agents.

          6.   Conditions.  The obligation of any Agent, as agent of the
Company, at any time (a "Solicitation Time") to solicit offers to purchase the
Securities, the obligation of any Agent to purchase Securities as principal
pursuant to any Terms Agreement or otherwise, and the obligation of any other
purchaser to purchase Securities shall in each case be subject (1) to the
condition that all representations and warranties of the Company contained
herein and all statements of officers of the Company made in any certificate
furnished pursuant to the provisions hereof are true and correct (i) in the case
of an Agent's obligation to solicit offers to purchase Securities, at and as of
such Solicitation Time and (ii) in the case of any Agent's or any other
purchaser's obligation to purchase Securities, at and as of the time the Company
accepts the offer to purchase such Securities and at and as of the related Time
of Delivery or time of purchase, as the case may be; (2) to the condition that
at or prior to such Solicitation Time, time of acceptance, Time of Delivery or
time of purchase, as the case may be, the Company shall have complied with all
its agreements and all conditions on its part to be performed or satisfied
hereunder; and (3) to the following additional conditions when and as specified:

          (a) Prior to such Solicitation Time or Time of Delivery or time of
     purchase, as the case may be:

               (i) the Prospectus as amended or supplemented (including, if
          applicable, the Pricing Supplement) with respect to such Securities
          shall have been filed with the Commission pursuant to Rule 424(b)
          under the Securities Act within the applicable time period prescribed
          for such filing by the Securities Act; no stop

                                      -15-
<PAGE>
 
          order suspending the effectiveness of the Registration Statement or
          any part thereof nor any order suspending the qualification of the
          Securities for offering or sale in any jurisdiction shall be in effect
          and no proceeding for such purpose shall have been initiated or
          threatened by the Commission or any state or other regulatory body;
          and all requests for additional information on the part of the
          Commission shall have been complied with to the reasonable
          satisfaction of such Agent;

               (ii) there shall not have occurred any downgrading, nor shall any
          notice have been given of (A) any intended or potential downgrading or
          (B) any review or possible change that does not indicate an
          improvement, in the rating accorded any securities of or guaranteed by
          the Company by any "nationally recognized statistical rating
          organization", as such term is defined for purposes of Rule 436(g)(2)
          under the Securities Act;

               (iii)  there shall not have been any material adverse change or
          any development involving a prospective material adverse change in or
          affecting the general affairs, business, prospects, management,
          financial position, stockholders' equity or results of operations of
          the Company and its subsidiaries, taken as a whole, otherwise than as
          set forth or contemplated in the Prospectus, as amended or
          supplemented to such Solicitation Time or at the time such offer to
          purchase was made, the effect of which in the judgment of the
          applicable Agent makes it impracticable or inadvisable to market the
          Securities on the terms and in the manner contemplated in the
          Prospectus, as so amended or supplemented; and

               (iv)(A) trading generally shall not have been suspended or

          banking activities in New York or in Pennsylvania shall not have been
          declared by either Federal or the relevant state authorities, or (D)
          there shall not have occurred any outbreak or escalation of
          hostilities or any change in financial markets or any calamity or
          crisis that, in the judgment of such Agent or Agents or of such other
          purchaser, is material and adverse and that, in the judgment of such
          Agent or Agents or of such other purchaser, makes it impracticable to
          market the Securities on the terms and in the manner contemplated in
          the Prospectus as amended or supplemented at the Solicitation Time or
          at the time such offer to purchase was made.

          (b) On the Commencement Date, and in the case of a purchase of
     Securities by an Agent as principal pursuant to a Terms Agreement or
     otherwise, if called for by the applicable Terms Agreement or other
     agreement, at the corresponding Time of Delivery, Augustine A. Mazzei, Jr.,
     Senior Vice President and Chief Legal Officer of the Company, shall have
     furnished to the relevant Agent or Agents his written opinion, dated

                                      -16-
<PAGE>
 
     the Commencement Date or Time of Delivery, as the case may be, in form and
     substance satisfactory to such Agent or Agents, to the effect that:

               (i) the Company has been duly incorporated and is validly
          existing as a corporation in good standing under the laws of the
          jurisdiction of its incorporation, with power and authority (corporate
          and other) to own its properties and conduct its business as described
          in the Prospectus as amended or supplemented;

               (ii) the Company has been duly qualified as a foreign corporation
          for the transaction of business and is in good standing under the laws
          of each other jurisdiction in which it owns or leases properties, or
          conducts any business, so as to require such qualifications, other
          than where the failure to be so qualified or in good standing would
          not have a material adverse effect on the Company and its subsidiaries
          taken as a whole;

               (iii)  each of the Company's subsidiaries has been duly
          incorporated and is validly existing as a corporation under the laws
          of its jurisdiction of incorporation with power and authority
          (corporate and other) to own its properties and conduct its business
          as described in the Prospectus, as amended or supplemented, and has
          been duly qualified as a foreign corporation for the transaction of
          business and is in good standing under the laws of each jurisdiction
          in which it owns or leases properties, or conducts any business, so as
          to require such qualification, other than where the failure to be so
          qualified and in good standing would not have a material adverse
          effect on the Company and its subsidiaries taken as a whole; and all
          of the issued shares of capital stock of each subsidiary have been
          duly and validly authorized and issued, are fully paid and non-
          assessable, and (except in the case of foreign subsidiaries, for
          directors' qualifying shares) are owned directly or indirectly by the
          Company, free and clear of all liens, encumbrances, equities or
          claims;

               (iv) other than as set forth or contemplated in the Prospectus,
          as amended or supplemented, there are no legal or governmental
          investigations, actions, suits or proceedings pending or, to the best
          of such counsel's knowledge, threatened against or affecting the
          Company or any of its subsidiaries or any of their respective property
          or to which the Company or any of its subsidiaries is or may be a
          party or to which any property of the Company or its subsidiaries is
          or may be subject which, if determined adversely to the Company or any
          of its subsidiaries, could individually or in the aggregate have, or
          reasonably be expected to have, a material adverse effect on the
          general affairs, business, prospects, management, financial position,
          stockholders' equity or results of operations of the Company and its
          subsidiaries taken as a whole; to the best of such counsel's
          knowledge, no such proceedings are threatened or contemplated by
          governmental authorities or threatened by others; and such counsel
          does not know of any statutes, regulations, contracts or other
          documents that are required to be filed as an exhibit to the
          Registration Statement or required to be described in the Registration
          Statement or the Prospectus, as amended or supplemented, which are not
          filed or described as required;

                                      -17-

               (v)  neither the Company nor any of its subsidiaries is, or
          with the giving of notice or lapse of time or both would be, in
          violation of or in default under, its Restated Articles of
          Incorporation or By-Laws or any indenture, mortgage, deed of trust,
          loan agreement or other agreement or instrument known to such counsel
          to which the Company or any of its subsidiaries is a party or by which
          it or any of them or any of their respective properties is bound,
          except for violations and defaults which individually and in the
          aggregate are not material to the Company and its subsidiaries taken
          as a whole or to the holders of the Securities; the issue and sale of
          the Securities and the performance by the Company of its obligations
          under the Securities, the Indenture, this Agreement and any applicable
          Terms Agreement or other agreement pursuant to which an Agent
          purchases Securities as principal and the consummation of the
          transactions herein and therein contemplated will not conflict with or
          result in a breach of any of the terms or provisions of, or constitute
          a default under, any indenture, mortgage, deed of trust, loan
          agreement or other agreement or instrument known to such counsel to
          which the Company or any of its subsidiaries is a party or by which
          the Company or any of its subsidiaries is bound or to which any of the
          property or assets of the Company or any of its subsidiaries is
          subject, nor will any such action result in any violation of the
          provisions of the Restated Articles of Incorporation or the By-Laws of
          the Company or any applicable law or statute or any order, rule or
          regulation of any court or governmental agency or body having
          jurisdiction over the Company, its subsidiaries or any of their
          respective properties;

               (vi) no consent, approval, authorization, order, license,
          registration or qualification of or with any court or governmental
          agency or body is required for the issue and sale of the Securities or
          the consummation of the other transactions contemplated by this
          Agreement, any applicable Terms Agreement or other agreement pursuant
          to which an Agent purchases Securities as principal, or the Indenture,
          except such consents, approvals, authorizations, orders, licenses,
          registrations or qualifications as have been obtained under the
          Securities Act and the Trust Indenture Act and as may be required
          under state securities or Blue Sky laws in connection with offers and
          sales of the Securities from the Company and with purchases of
          Securities or from the Pennsylvania Public Utility Commission and the
          Kentucky Public Service Commission in connection with the issuance and
          sale of the Securities;

               (vii)  such counsel (A) is of the opinion that each document
          incorporated by reference in the Registration Statement and Prospectus
          as amended or supplemented (other than the financial statements and
          related schedules therein, as to which such counsel need express no
          opinion) complied as to form when filed with the Commission in all
          material respects with the Exchange Act, (B) believes that (except for
          the financial statements included therein as to which such counsel
          need express no belief) each part of the Registration Statement
          (including the documents incorporated by reference therein) filed with
          the Commission pursuant to the Securities Act relating to the
          Securities, when such part became effective, did not and, as of the
          date such opinion is delivered, does not, contain an untrue statement
          of a material fact or omit to state a material fact required to be
          stated

                                      -18-

          therein or necessary to make the statements therein not misleading,
          (C) is of the opinion that the Registration Statement and the
          Prospectus and any amendments and supplements thereto (except for the
          financial statements included therein as to which such counsel need
          express no opinion) comply as to form in all material respects with
          the requirements of the Securities Act and the Trust Indenture Act and
          (D) believes that (except for the financial statements included
          therein as to which such counsel need express no belief) the
          Registration Statement and the Prospectus, as amended or supplemented,
          if applicable, as of the date such opinion is delivered does not
          contain any untrue statement of a material fact or omit to state a
          material fact required to be stated therein or necessary to make the
          statements therein not misleading; provided, that in the case of an
          opinion delivered on the Commencement Date or pursuant to Section 4(i)
          hereof, the opinion and belief set forth in clauses (C) and (D) above
          shall be deemed not to cover information concerning an offering of
          particular Securities to the extent such information will be set forth
          in a supplement to the Basic Prospectus;

               (viii)   the Company is not and, after giving effect to any
          offering and sale of Securities, will not be an "investment company"
          or entity "controlled" by an "investment company", as such terms are
          defined in the Investment Company Act;

               (ix) each of the Company and its subsidiaries owns, possesses or
          has obtained all licenses, permits, certificates, consents, orders,
          approvals and other authorizations from, and has made all declarations
          and filings with, all federal, state, local and other governmental
          authorities (including foreign regulatory agencies), all self-
          regulatory organizations and all courts and other tribunals, domestic
          or foreign, necessary to own or lease, as the case may be, and to
          operate its properties and to carry on its business as conducted as of
          the Commencement Date or Time of Delivery, as the case may be, except
          where the failure to so own or possess or to have so obtained or made
          would not, singly or in the aggregate, have a material adverse effect
          on the Company and its subsidiaries taken as a whole, and neither the
          Company nor any such subsidiary has received any actual notice of any
          proceeding relating to revocation or modification of any such license,
          permit, certificate, consent, order, approval or other authorization,
          except as described in the Registration Statement and the Prospectus;
          and each of the Company and its subsidiaries is in compliance with all
          laws and regulations relating to the conduct of its business as
          conducted as of the Commencement Date or Time of Delivery, as the case
          may be, except where the failure to be in compliance would not, singly
          or in the aggregate, have a material adverse effect on the Company and
          its subsidiaries taken as a whole;

               (x) the Company and its subsidiaries have good and marketable
          title in fee simple to all real property and good and marketable title
          to all personal property owned by them, in each case free and clear of
          all liens, encumbrances and defects except such as are described or
          referred to in the Prospectus or such as do not materially affect the
          value of such property and do not interfere with the use made and
          proposed to be made of such property by the Company and its
          subsidiaries; and any real property and buildings held under lease by
          the Company

                                      -19-
<PAGE>
 
          and its subsidiaries are held by them under valid, existing and
          enforceable leases with such exceptions as are not material and do not
          interfere with the use made or proposed to be made of such property
          and buildings by the Company or its subsidiaries; and

               (xi) each of the Company and its subsidiaries is in compliance
          with all Environmental Laws, except, in each case, where
          noncompliance, individually or in the aggregate, would not have a
          material adverse effect on the Company and its subsidiaries taken as a
          whole; and there are no legal or governmental proceedings pending or,
          to the knowledge of such counsel, threatened against or affecting the
          Company or any of its subsidiaries under any Environmental Law which,
          individually or in the aggregate, could reasonably be expected to have
          a material adverse effect on the Company and its subsidiaries taken as
          a whole.

          In rendering such opinions, such counsel may rely (A) as to matters
     involving the application of the laws other than the laws of the United
     States and the Commonwealth of Pennsylvania, to the extent such counsel
     deems proper and to the extent specified in such opinion, if at all, upon
     an opinion or opinions (in form and substance reasonably satisfactory to
     the Agents' counsel) of other counsel reasonably acceptable to the Agents'
     counsel, familiar with the applicable laws; and (B) as to matters of fact,
     to the extent such counsel deems proper, on certificates of responsible
     officers of the Company and certificates or other written statements of
     officials of jurisdictions having custody of documents respecting the
     corporate existence or good standing of the Company.  The opinion of such
     counsel for the Company shall state that the opinion of any such other
     counsel upon which he relied is in form satisfactory to such counsel and,
     in such counsel's opinion, the Agents and he are justified in relying
     thereon.

          (c) On the Commencement Date, and in the case of a purchase of
     Securities by an Agent as principal pursuant to a Terms Agreement or
     otherwise, if called for by the applicable Terms Agreement or other
     agreement, at the corresponding Time of Delivery, Reed Smith Shaw & McClay,
     counsel to the Company, shall have furnished to the relevant Agent or
     Agents their written opinion, dated the Commencement Date or Time of
     Delivery, as the case may be, in form and substance satisfactory to such
     Agent or Agents, to the effect that:

               (i) the Company has been duly incorporated and is validly
          existing as a corporation in good standing under the laws of the
          jurisdiction of its incorporation, with power and authority (corporate
          and other) to own its properties and conduct its business as described
          in the Prospectus as amended or supplemented;

               (ii) this Agreement and any applicable Terms Agreement have been
          duly authorized, executed and delivered by the Company and are valid
          and binding agreements except as rights to indemnity and contribution
          hereunder and thereunder may be limited by applicable law;

               (iii)  the Securities have been duly authorized and, when
          executed and authenticated in accordance with the terms of the
          Indenture and delivered to and

                                      -20-

          paid for by any purchaser of Securities sold through an Agent as agent
          or any Agent as principal pursuant to any Terms Agreement or other
          agreement, will constitute valid and binding obligations of the
          Company entitled to the benefits provided by the Indenture except as
          (A) the enforceability thereof may be limited by bankruptcy,
          insolvency or similar laws affecting creditors' rights generally and
          (B) rights of acceleration and the availability of equitable remedies
          may be limited by equitable principles of general applicability;

               (iv) the Indenture has been duly qualified under the Trust
          Indenture Act and has been duly authorized, executed and delivered by
          the Company and constitutes a valid and binding instrument of the
          Company except as (A) the enforceability thereof may be limited by
          bankruptcy, insolvency or similar laws affecting creditors' rights
          generally and (B) rights of acceleration and the availability of
          equitable remedies may be limited by equitable principles of general
          applicability;

               (v) the issue and sale of the Securities and the performance by
          the Company of its obligations under the Securities, the Indenture,
          this Agreement and any applicable Terms Agreement or other agreement
          pursuant to which an Agent purchases Securities as principal and the
          consummation of the transactions herein and therein contemplated will
          not conflict with or result in a breach of any of the terms or
          provisions of, or constitute a default under, any indenture, mortgage,
          deed of trust, loan agreement or other agreement or instrument known
          to such counsel to which the Company or any of its subsidiaries is a
          party or by which the Company or any of its subsidiaries is bound or
          to which any of the property or assets of the Company or any of its
          subsidiaries is subject, nor will any such action result in any
          violation of the provisions of the Restated Articles of Incorporation
          or the By-Laws of the Company or any applicable law or statute or any
          order, rule or regulation of any court or governmental agency or body
          having jurisdiction over the Company, its subsidiaries or any of their
          respective properties;

               (vi) no consent, approval, authorization, order, license,
          registration or qualification of or with any court or governmental

          Agreement, any applicable Terms Agreement or other agreement pursuant
          to which an Agent purchases Securities as principal, or the Indenture,
          except such consents, approvals, authorizations, orders, licenses,
          registrations or qualifications as have been obtained under the
          Securities Act and the Trust Indenture Act and as may be required
          under state securities or Blue Sky laws in connection with offers and
          sales of the Securities from the Company and with purchases of
          Securities or from the Pennsylvania Public Utility Commission and the
          Kentucky Public Service Commission in connection with the issuance and
          sale of the Securities;

               (vii)  the statements in the Prospectus under "             ",

          "Description of the Debt Securities" and "Plan of Distribution", in
          the Prospectus incorporated by reference from Item 3 of Part 1 of the
          Company's Annual Report

          on Form 10-K most recently filed with the Commission, in the
          Prospectus incorporated by reference from Item 1 of Part II of the
          Company's Quarterly Reports on Form 10-Q, if any, filed with the
          Commission since such Annual Report, in the Prospectus incorporated by
          reference from Item 5 of the Company's Current Reports on Form 8-K, if
          any, filed with the Commission since such Annual Report and in the
          Registration Statement in Item 15, insofar as such statements
          constitute a summary of the legal matters, documents or proceedings
          referred to therein, fairly present the information called for with
          respect to such legal matters, documents or proceedings;

               (viii)   such counsel is of the opinion ascribed to it in the
          Prospectus under the caption "Taxation", if any; and

               (ix) such counsel (A) is of the opinion that the Registration
          Statement and the Prospectus and any amendments and supplements
          thereto (except for the financial statements included therein as to
          which such counsel need express no opinion) comply as to form in all
          material respects with the requirements of the Securities Act and the
          Trust Indenture Act and (B) believes that (except for the financial
          statements included therein as to which such counsel need express no
          belief) the Registration Statement and the Prospectus, as amended or
          supplemented, if applicable, as of the date such opinion is delivered
          does not contain any untrue statement of a material fact or omit to
          state a material fact required to be stated therein or necessary to
          make the statements therein not misleading; provided, that in the case
          of an opinion delivered on the Commencement Date or pursuant to
          Section 4(i) hereof, the opinion and belief set forth above shall be
          deemed not to cover information concerning an offering of particular
          Securities to the extent such information will be set forth in a
          supplement to the Basic Prospectus;

          In rendering such opinions, such counsel may rely (A) as to matters
     involving the application of the laws other than the laws of the United
     States and the Commonwealth of Pennsylvania, to the extent such counsel
     deems proper and to the extent specified in such opinion, if at all, upon
     an opinion or opinions (in form and substance reasonably satisfactory to
     the Agents' counsel) of other counsel reasonably acceptable to the Agents'
     counsel, familiar with the applicable laws; and (B) as to matters of fact,
     to the extent such counsel deems proper, on certificates of responsible
     officers of the Company and certificates or other written statements of
     officials of jurisdictions having custody of documents respecting the
     corporate existence or good standing of the Company.  The opinion of such
     counsel for the Company shall state that the opinion of any such other
     counsel upon which they relied is in form satisfactory to such counsel and,
     in such counsel's opinion, the Agents and they are justified in relying
     thereon.  With respect to the matters to be covered in subparagraphs
     (c)(vii) and (c)(ix) above, counsel may state their opinion and belief is
     based upon their participation in the preparation of the Registration
     Statement and the Prospectus and any amendment or supplement thereto (other
     than the documents incorporated by reference therein) and review and
     discussion of the contents thereof (including the documents incorporated by
     reference therein) but is without independent check or verification except
     as specified.

          (d) On the Commencement Date and, in the case of a purchase of
     Securities by an Agent as principal pursuant to a Terms Agreement or
     otherwise, if called for by the applicable Terms Agreement or other
     agreement, at the corresponding Time of Delivery, Kirkpatrick & Lockhart
     LLP, counsel to the Agents, shall have furnished to the relevant Agent or
     Agents such opinion or opinions, dated the Commencement Date or Time of
     Delivery, as the case may be, with respect to the validity of the Indenture
     and the Securities, the Registration Statement, the Prospectus as amended
     or supplemented and other related matters as such Agent or Agents may
     reasonably request, and in each case such counsel shall have received such
     papers and information as they may reasonably request to enable them to
     pass upon such matters.

          (e) On the Commencement Date and, in the case of a purchase of
     Securities by an Agent as principal pursuant to a Terms Agreement or
     otherwise, if called for by the applicable Terms Agreement or other
     agreement, at the corresponding Time of Delivery, Ernst & Young LLP shall
     have furnished to the relevant Agents a letter or letters, dated as of the
     Commencement Date or such Time of Delivery, as the case may be, in form and
     substance satisfactory to such Agents, containing statements and
     information of the type customarily included in accountants' "comfort
     letters" to underwriters with respect to the financial statements and
     certain financial information contained in the Registration Statement and
     the Prospectus.

          (f) On the Commencement Date and, in the case of a purchase of
     Securities by an Agent as principal pursuant to a Terms Agreement or
     otherwise, if called for by the applicable Terms Agreement or other
     agreement, at the corresponding Time of Delivery, the relevant Agent or
     Agents shall have received a certificate or certificates signed by an
     executive officer of the Company, with specific knowledge about the
     Company's financial matters, dated the Commencement Date or Time of
     Delivery, as the case may be, satisfactory to such Agent or Agents to the
     effect set forth in Sections 6(a)(i) and (ii) above and to the further
     effect that (1) the representations and warranties of the Company contained
     herein are true and correct on and as of the Commencement Date or Time of
     Delivery, as the case may be, as if made on and as of such date, (2) the
     Company has complied with all agreements and all conditions on its part to
     be performed or satisfied hereunder or under the applicable Terms Agreement
     or other agreement at or prior to the Commencement Date or Time of
     Delivery, as the case may be, and (3) there has not occurred any material
     adverse change, or any development involving a prospective material adverse
     change, in or affecting the general affairs, business, prospects,
     management, financial position, stockholders' equity or results of
     operations of the Company and its subsidiaries taken as a whole from that
     set forth in or contemplated by the Registration Statement or the
     Prospectus.

          (g) On the Commencement Date and at each Time of Delivery, the Company
     shall have furnished to the relevant Agent or Agents such further
     certificates, information and documents as such Agent or Agents may
     reasonably request.

          7.   Indemnification and Contribution.  The Company agrees to
indemnify and hold harmless each Agent and each person, if any, who controls
such Agent within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act from and against any and all losses, claims,
damages and liabilities (including without limitation the legal

                                      -23-
<PAGE>
 
fees and other expenses incurred in connection with any suit, action or
proceeding or any claim asserted) caused by any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement or
the Prospectus (as amended or supplemented if the Company shall have furnished
any amendments or supplements thereto) or any preliminary prospectus, or caused
by any omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading,
except insofar as such losses, claims, damages or liabilities are caused by any
untrue statement or omission or alleged untrue statement or omission made in
reliance upon and in conformity with information relating to any Agent furnished
to the Company in writing by such Agent expressly for use therein.

          Each Agent agrees, severally and not jointly, to indemnify and hold
harmless the Company, its directors, its officers who sign the Registration
Statement and each person who controls the Company within the meaning of Section
15 of the Securities Act and Section 20 of the Exchange Act to the same extent
as the foregoing indemnity from the Company to each Agent, but only with
reference to information relating to such Agent furnished to the Company in
writing by such Agent expressly for use in the Registration Statement, the
Prospectus, any amendment or supplement thereto, or any preliminary prospectus.

          If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any person in respect of which indemnity may be sought pursuant to either of the
two preceding paragraphs, such person (the "Indemnified Person") shall promptly
notify the person against whom such indemnity may be sought (the "Indemnifying
Person") in writing, and the Indemnifying Person, upon request of the
Indemnified Person, shall retain counsel reasonably satisfactory to the
Indemnified Person to represent the Indemnified Person and any others the
Indemnifying Person may designate in such proceeding and shall pay the fees and
expenses of such counsel related to such proceeding.  In any such proceeding,
any Indemnified Person shall have the right to retain its own counsel, but the
fees and expenses of such counsel shall be at the expense of such Indemnified
Person unless (i) the Indemnifying Person and the Indemnified Person shall have
mutually agreed to the contrary, (ii) the Indemnifying Person has failed within
a reasonable time to retain counsel reasonably satisfactory to the Indemnified
Person or (iii) the named parties in any such proceeding (including any
impleaded parties) include both the Indemnifying Person and the Indemnified
Person and representation of both parties by the same counsel would be
inappropriate due to actual or potential differing interests between them.  It
is understood that the Indemnifying Person shall not, in connection with any
proceeding or related proceeding in the same jurisdiction, be liable for the
fees and expenses of more than one separate firm (in addition to any local
counsel) for all Indemnified Persons, and that all such fees and expenses shall
be reimbursed as they are incurred.  Any such separate firm for the Agents and
such control persons of the Agents shall be designated in writing by [J.P.
Morgan Securities Inc.] or, if [J.P. Morgan Securities Inc.] is not an
Indemnified Party, by the Agents that are Indemnified Parties and any such
separate firm for the Company, its directors, its officers who sign the
Registration Statement and such control persons of the Company shall be
designated in writing by the Company.  The Indemnifying Person shall not be
liable for any settlement of any proceeding effected without its written
consent, but if settled with such consent or if there be a final judgment for
the plaintiff, the Indemnifying Person agrees to indemnify any Indemnified
Person from and against any loss or liability by reason of such settlement or
judgment.  Notwithstanding the foregoing sentence, if at any time an Indemnified
Person shall have requested an Indemnifying Person to reimburse the Indemnified
Person for fees and expenses of counsel as

                                      -24-
<PAGE>
 
contemplated by the third sentence of this paragraph, the Indemnifying Person
agrees that it shall be liable for any settlement of any proceeding effected
without its written consent if (i) such settlement is entered into more than 30
days after receipt by such Indemnifying Person of the aforesaid request and (ii)
such Indemnifying Person shall not have reimbursed the Indemnified Person in
accordance with such request prior to the date of such settlement.  No
Indemnifying Person shall, without the prior written consent of the Indemnified
Person, effect any settlement of any pending or threatened proceeding in respect
of which any Indemnified Person is or could have been a party and indemnity
could have been sought hereunder by such Indemnified Person, unless such
settlement includes an unconditional release of such Indemnified Person from all
liability on claims that are the subject matter of such proceeding.

          If the indemnification provided for in the first and second paragraphs
of this Section 7 is unavailable to an Indemnified Person or insufficient in
respect of any losses, claims, damages or liabilities referred to therein, then
each Indemnifying Person under such paragraph, in lieu of indemnifying such
Indemnified Person thereunder, shall contribute to the amount paid or payable by
such Indemnified Person as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company on the one hand and each Agent on the other
from the offering of the Securities 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 each Agent
on the other in connection with the statements or omissions that resulted in
such losses, claims, damages or liabilities, as well as any other relevant
equitable considerations.  The relative benefits received by the Company on the
one hand and each Agent on the other in connection with any offering of
Securities shall be deemed to be in the same respective proportions as the net
proceeds from the offering of such Securities (before deducting expenses)
received by the Company and the total discounts and commissions received by each
Agent in respect thereof bear to the aggregate offering price of such
Securities.  The relative fault of the Company on the one hand and of each Agent
on the other shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company or by such Agent and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

          The Company and each Agent agree that it would not be just and
equitable if contribution pursuant to this Section 7 were determined by pro rata
                                                                        --- ----
allocation (even if all Agents were treated as one entity for such purpose) or
by any other method of allocation that does not take account of the equitable
considerations referred to in the immediately preceding paragraph.  The amount
paid or payable by an Indemnified Person as a result of the losses, claims,
damages and liabilities referred to above in this Section 7 shall be deemed to
include, subject to the limitations set forth above, any legal or other expenses
incurred by such Indemnified Person in connection with investigating or
defending any such action or claim.  Notwithstanding the provisions of this
Section 7, in no event shall an Agent be required to contribute any amount in
excess of the amount by which the total price at which the relevant Securities
that were sold by or through such Agent exceeds the amount of any damages that
such Agent has otherwise been required to pay by reason of such 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
Securities Act) shall be entitled to contribution from any person who was not
guilty of such

                                      -25-

fraudulent misrepresentation.  The obligation of each Agent to contribute
pursuant to this Section 7 is several in proportion to the principal amount of
the Securities the sale of which by or through such Agent gave rise to such
losses, claims, damages or liabilities bears to the aggregate principal amount
of the Securities the sale of which by or through any Agent gave rise to such
losses, claims, damages or liabilities and is not joint.

          The indemnity and contribution agreements contained in this Section 7
are in addition to any liability which any Indemnifying Person may otherwise
have at law or in equity to any Indemnified Persons referred to above.

          8.   Termination.

          (a) This Agreement may be terminated at any time (i) by the Company
     with respect to any or all of the Agents or (ii) by any Agent with respect
     to itself only, in each case upon the giving of written notice of such
     termination to each other party hereto.  Any Terms Agreement shall be
     subject to termination in the absolute discretion of the Agent or Agents
     that are parties thereto on the terms set forth or incorporated by
     reference therein.  The termination of this Agreement shall not require
     termination of any agreement by an Agent to purchase Securities as
     principal (whether pursuant to a Terms Agreement or otherwise) and the
     termination of such an agreement shall not require termination of this
     Agreement.  In the event that this Agreement is terminated with respect to
     any Agent, (x) this Agreement shall remain in full force and effect with
     respect to any Agent as to which such termination has not occurred, (y)
     this Agreement shall remain in full force and effect with respect to the
     rights and obligations of any party which have previously accrued or which
     relate to Securities which are already issued, agreed to be issued or the
     subject of a pending offer at the time of such termination and (z) in any
     event, the provisions of the fourth paragraph of Section 2(a), Section
     2(c), the last sentence of Section 4(d) and Sections 4(f), 4(g), 5, 7, 9,
     10, 12 and 15 hereof shall survive; provided, that if at the time of
     termination an offer to purchase Securities has been accepted by the
     Company but the time of delivery to the purchaser or its agent of such
     Securities has not yet occurred, the provisions of Sections 2(b), 2(d),
     4(a) through 4(e), 4(h) through 4(k) and 6 hereof shall also survive.  If
     any Terms Agreement is terminated, the provisions of the last sentence of
     Section 4(d) and Sections 2(b), 2(d), 4(a), 4(b), 4(e), 4(g) through 4(k),
     5, 6, 7, 9, 10, 12 and 15 hereof (which shall have been incorporated by
     reference in such Terms Agreement) shall survive.

          (b) If this Agreement or any Terms Agreement shall be terminated by an
     Agent or Agents because of any failure or refusal on the part of the
     Company to comply with the terms or to fulfill any of the conditions of
     this Agreement or any Terms Agreement or if for any reason the Company
     shall be unable to perform its obligations under this Agreement or any
     Terms Agreement or any condition of any Agent's obligations cannot be
     fulfilled, the Company agrees to reimburse such Agent or Agents as have so
     terminated this Agreement with respect to themselves, severally, for all
     out-of-pocket expenses (including the fees and expenses of their counsel)
     reasonably incurred by such Agent or Agents in connection with this
     Agreement or the offering of Securities.

                                      -26-
<PAGE>
 
          9.  Position of the Agents.  Each Agent, in soliciting offers to
purchase Securities from the Company and in performing the other obligations of
such Agent hereunder (other than in respect of any purchase by an Agent as
principal pursuant to a Terms Agreement or otherwise), is acting solely as agent
for the Company and not as principal and does not assume any obligation towards
or relationship of agency or trust with any purchaser of Securities.  Each Agent
will make reasonable efforts to assist the Company in obtaining performance by
each purchaser whose offer to purchase Securities from the Company was solicited
by such Agent and has been accepted by the Company, but such Agent shall not
have any liability to the Company in the event such purchase is not consummated
for any reason.  If the Company shall default on its obligation to deliver
Securities to a purchaser whose offer it has accepted, the Company shall (i)
hold the relevant Agent harmless against any loss, claim, damage or liability
arising from or as a result of such default by the Company and (ii)
notwithstanding such default, pay to the Agent that solicited such offer any
commission to which it would be entitled in connection with such sale.

          10.  Representations and Indemnities to Survive.  The respective
indemnities and contribution agreements, representations, warranties and other
statements of the Company, its officers and the Agents set forth in or made
pursuant to this Agreement or any agreement by an Agent to purchase Securities
as principal shall remain operative and in full force and effect regardless of
any termination of this Agreement or any such agreement, any investigation made
by or on behalf of any Agent or any controlling person of any Agent or the
Company or any officer or director or controlling person of the Company and
shall survive each delivery of and payment for any of the Securities.

          11.  Notices.  Except as otherwise specifically provided herein or in
the Administrative Procedures, all statements, requests, notices and advises
hereunder shall be in writing and effective only on receipt, and will be
delivered by hand, by mail (postage prepaid), by telegram (charges prepaid) or
by telex.  Communications to the Agents will be sent, in the case of J.P. Morgan
Securities Inc., to 60 Wall Street, New York, New York 10260 (telefax:   (212)
648-5909), Attention:  Medium-Term Note Desk, in the case of             , to

President-Finance, and Treasurer (telefax number: (412) 553-5875).

          12.  Successors.  This Agreement and any Terms Agreement shall be
binding upon, and inure to the benefit of, each Agent and the Company, their
respective successors and the officers, directors and controlling persons
referred to in Section 7 hereof and (to the extent expressly provided in Section
6 hereof) the purchasers of Securities, and no other person shall acquire or
have any right or obligation under or by virtue of this Agreement or any Terms
Agreement.

          13.  Amendments.  This Agreement may be amended or supplemented if,
but only if, such amendment or supplement is in writing and is signed by the
Company and each Agent; provided, that the Company may from time to time, on 7
days prior written notice to the Agents but without the consent of any Agent,
amend this Agreement to add as a party hereto one or more additional firms
registered under the Exchange Act, whereupon each such firm shall become an
Agent hereunder on the same terms and conditions as the other Agents that are
parties

                                      -27-
<PAGE>
 
hereto.  The Agents shall sign any amendment or supplement giving effect to the
addition of any such firm as an Agent under this Agreement.

          14.  Business Day.  Time shall be of the essence in this Agreement and
any Terms Agreement.  As used herein, the term "business day" shall mean any day
which is not a Saturday or Sunday or legal holiday or a day on which banks in
New York City or Pittsburgh, Pennsylvania are required or authorized by law or
executive order to close.

          15.  Applicable Law.  This Agreement and any Terms Agreement shall be
governed by and construed in accordance with the laws of the State of New York,
without giving effect to the conflicts of laws provisions thereof.

          16.  Counterparts.  This Agreement and any Terms Agreement may be
signed in counterparts, each of which shall be an original and all of which
together shall constitute one and the same instrument.

          17.  Headings.  The headings of the sections of this Agreement have
been inserted for convenience of reference only and shall not be deemed a part
of this Agreement.

                          MEDIUM-TERM NOTES, SERIES __
                           ADMINISTRATIVE PROCEDURES

                           _________________________



          The Medium-Term Notes, Series ___ (the "Notes"), are to be offered on
a continuous basis by Equitable Resources, Inc. (the "Company").  Each of
_______________ and _______________ (each, an "Agent") has agreed to solicit
offers to purchase the Notes in registered form.  The Notes are being sold
pursuant to a Distribution Agreement dated as of __________ __, 199_ (the
"Agreement") between the Company and the Agents.  In the Agreement, each Agent
has agreed to use reasonable efforts to solicit purchases of the Notes.  Each
Agent, as principal, may purchase Notes for its own account and, if such Agent
so elects, the Company and such Agent will enter into a Terms Agreement, as
contemplated by the Agreement.  The Company may also solicit offers to purchase
and may sell Notes directly on its own behalf to investors (other than broker-
dealers).

          The Notes will be issued under an Indenture dated as of June __, 1996
(as supplemented or amended from time to time, the "Indenture") between the
Company and Bank of Montreal Trust Company, as trustee (the "Trustee").  The
Trustee will be the Registrar, Calculation Agent, Authenticating Agent and
Paying Agent for the Notes, and will perform the duties specified herein.  Notes
will bear interest at a fixed rate (the "Fixed Rate Notes"), which may be zero
in the case of certain original issue discount notes (the "OID Notes"), or at
floating rates (the "Floating Rate Notes").  Fixed Rate Notes may pay a level
amount in respect of both interest and principal amortized over the life of the
Notes ("Amortizing Notes").  Each Note will be represented by either a Global
Security (as defined below) delivered to the Trustee, as agent for The
Depository Trust Company ("DTC"), and recorded in the book-entry system
maintained by DTC (a "Book-Entry Note") or a certificate delivered to the holder
thereof or a person designated by such holder (a "Certificated Note").  Except
in limited circumstances, an owner of a Book-Entry Note will not be entitled to
receive a Certificated Note.

          Book-Entry Notes, which may be payable solely in U. S. dollars, will
be issued in accordance with the administrative procedures set forth in Part I
hereof as they may subsequently be amended as the result of changes in DTC's
operating procedures, and Certificated Notes will be issued in accordance with
the administrative procedures set forth in Part II hereof.  Unless otherwise
defined herein, terms defined in the Indenture or the Notes shall be used herein
as therein defined.
<PAGE>
  
            PART I:  ADMINISTRATIVE PROCEDURES FOR BOOK-ENTRY NOTES

          In connection with the qualification of the Book-Entry Notes for
eligibility in the book-entry system maintained by DTC, the Trustee will perform
the custodial, document control and administrative functions described below, in
accordance with its respective obligations under a Letter of Representation from
the Company and the Trustee to DTC, dated as of the date hereof (the "Letter of
Representation"), and a Medium-Term Note Certificate Agreement between the
Trustee and DTC, dated as of _____________ __, 19__, and its obligations as a
participant in DTC, including DTC's Same-Day Funds Settlement System ("SDFS").

Issuance:           On any date of settlement (as defined under "Settlement"
                    below) for one or more Book-Entry Notes, the Company will
                    issue a single global security in fully registered form
                    without coupons (a "Global Security") representing up to
                    U.S. $__________ principal amount of all such Notes that
                    have the same Maturity Date, redemption or repayment
                    provisions, Interest Payment Dates, Original Issue Date,
                    original issue discount provisions (if any), and, in the
                    case of Fixed Rate Notes, Interest Rate, modified payment
                    upon acceleration (if any), amortization schedule (if any)
                    or, in the case of Floating Rate Notes, Initial Interest
                    Rate, Interest Payment Dates, Interest Payment Period,
                    Calculation Agent, Base Rate, Index Maturity, Interest Reset
                    Period, Interest Reset Dates, Spread or Spread Multiplier
                    (if any), Alternative Rate Event Spread (if any), Minimum
                    Interest Rate (if any) and Maximum Interest Rate (if any)
                    and, in each case, any other relevant terms (collectively,
                    "Terms").  Each Global Security will be dated and issued as
                    of the date of its authentication by the Trustee.  Each
                    Global Security will bear an "Interest Accrual Date," which
                    will be (i) with respect to an original Global Security (or
                    any portion thereof), its original issuance date and (ii)
                    with respect to any Global Security (or any portion thereof)
                    issued subsequently upon exchange of a Global Security, or
                    in lieu of a destroyed, lost or stolen Global Security, the
                    most recent Interest Payment Date to which interest has been
                    paid or duly provided for on the predecessor Global Security
                    or Securities (or if no such payment or provision has been
                    made, the original issuance date of the predecessor Global
                    Security), regardless of the date of authentication of such
                    subsequently issued Global Security.  Book-Entry Notes may
                    only be denominated and payable in U.S. dollars.  No Global
                    Security will represent (i) both Fixed Rate and Floating
                    Rate Book-Entry Notes or (ii) any Certificated Note.  [No
                    Note issued between a Record Date and the related Interest
                    Payment Date will be issued as a Global Security within the
                    meaning of the Indenture.]

Identification      The Company has arranged with the CUSIP Service Bureau of
Numbers:            Standard & Poor's Corporation (the "CUSIP Service Bureau")
                    for Securities representing the Book-Entry Notes.  The
                    Company has obtained from the CUSIP Service Bureau a written
                    list of such series of reserved CUSIP numbers and has
                    delivered to the Trustee and DTC the written list of 900
                    CUSIP numbers of such series.  The Trustee will assign CUSIP
                    numbers to Global Securities as described below under
                    Settlement Procedure "B".  DTC will notify the CUSIP Service
                    Bureau periodically of the CUSIP numbers that the Trustee
                    has assigned to Global Securities.  At any time when fewer
                    than 100 of the reserved CUSIP numbers remain unassigned to
                    Global Securities, the Trustee will so advise the Company
                    and, if it deems necessary, the Company will reserve
                    additional CUSIP numbers for assignment to Global Securities
                    representing Book-Entry Notes.  Upon obtaining such
                    additional CUSIP numbers, the Company will deliver a list of
                    such additional CUSIP numbers to the Trustee and DTC.

Registration:       Each Global Security will be registered in the name of Cede
                    & Co., as nominee for DTC, on the security register
                    maintained under the Indenture.  The beneficial owner of a
                    Book-Entry Note (or one or more indirect participants in DTC
                    designated by such owner) will designate one or more
                    participants in DTC with respect to such Note (the
                    "Participants") to act as agent or agents for such owner in
                    connection with the book-entry system maintained by DTC and
                    DTC will record in book-entry form, in accordance with
                    instructions provided by such Participants, a credit balance
                    with respect to such beneficial owner in such Note in the
                    account of such Participants.  The ownership interest of
                    such beneficial owner in such Note will be recorded through
                    the records of such Participants or through the separate
                    records of such Participants and one or more indirect
                    participants in DTC.

Transfers:          Transfers of a Book-Entry Note will be accompanied by book
                    entries made by DTC and, in turn, by Participants (and in
                    certain cases, one or more indirect participants in DTC)
                    acting on behalf of beneficial transferors and transferees
                    of such Note.

Exchanges:          The Trustee may deliver to DTC and the CUSIP Service Bureau
                    at any time a written notice of consolidation specifying (i)
                    the CUSIP numbers of two or more Outstanding Global
                    Securities that represent Book-Entry Notes having the same
                    Terms and for which interest has been paid to the same date,
                    (ii) a date, occurring at least thirty days after such
                    written notice is delivered and at least thirty days before
                    the next Interest Payment Date for such Book-Entry Notes, on
                    which such Global

                    Securities will be exchanged for a single replacement Global
                    Security and (iii) a new CUSIP number to be assigned to such
                    replacement Global Security.  Upon receipt of such a notice,
                    DTC will send to its Participants (including the Trustee) a
                    written reorganization notice to the effect that such
                    exchange will occur on such date. Prior to the specified
                    exchange date, the Trustee will deliver to the CUSIP Service
                    Bureau a written notice setting forth such exchange date and
                    the new CUSIP number and stating that, as of such exchange
                    date, the CUSIP numbers of the Global Securities to be
                    exchanged will no longer be valid.  On the specified
                    exchange date, the Trustee will exchange such Global
                    Securities for a single Global Security bearing the new
                    CUSIP number and a new Interest Accrual Date, and the CUSIP
                    numbers of the exchanged Global Securities will, in
                    accordance with CUSIP Service Bureau procedures, be canceled
                    and not immediately reassigned.  Notwithstanding the
                    foregoing, if the Global Securities to be exchanged exceed
                    $__________ in aggregate principal amount, one Global
                    Security will be authenticated and issued to represent each
                    $__________ principal amount of the exchanged Global
                    Securities and an additional Global Security will be
                    authenticated and issued to represent any remaining
                    principal amount of such Global Securities (see
                    "Denominations" below).

Maturities:         Each Book-Entry Note will mature on a date from nine months
                    to [30] years from its date of issue.

Notice of           The Trustee will give notice to DTC prior to each Redemption
Redemption and      Date or Repayment Date (as specified in the Note), if any,
Repayment Dates:    at the time and in the manner set forth in the Letter of
                    Representation.

Denominations:      Book-Entry Notes will be issued in principal amounts of
                    $__________ or an integral multiple of $1,000 in excess
                    thereof.  Global Securities will be denominated in principal
                    amounts not in excess of $__________.  If one or more Book-
                    Entry Notes having an aggregate principal amount in excess
                    of $__________ would, but for the preceding sentence, be
                    represented by a  single Global Security, then one Global
                    Security will be issued to represent each $__________
                    principal amount of such Book-Entry Note or Notes and an
                    additional Global Security will be issued to represent any
                    remaining principal amount of such Book-Entry Note or Notes.
                    In such a case, each of the Global Securities representing
                    such Book-Entry Note or Notes will be assigned the same
                    CUSIP number.

Interest:           General.  Interest on each Book-Entry Note will accrue from
                    the Interest Accrual Date of the Global Security
                    representing such

                    Note.  Unless otherwise specified therein, each payment of
                    interest on a Book-Entry Note will include interest accrued
                    to but excluding the Interest Payment Date; provided, that
                    in the case of Floating Rate Notes with respect to which the
                    Interest Reset Period is daily or weekly, interest payable
                    on any Interest Payment Date [(other than interest payable
                    on any date on which the principal thereof is payable, and,
                    if the Note is a Book-Entry Gap Note (as defined below),
                    other than interest payable on the first Interest Payment
                    Date after the Original Issue Date thereof)] will include
                    interest accrued through and including the Record Date
                    immediately preceding the Interest Payment Date, except that
                    at maturity or earlier redemption or repayment, the interest
                    payable will include interest accrued to, but excluding, the
                    Maturity Date or the date of redemption or repayment, as the
                    case may be.  Interest payable at the maturity or upon
                    redemption or repayment of a Book-Entry Note will be payable
                    to the person to whom the principal of such Note is payable.
                    Standard & Poor's Corporation will use the information
                    received in the pending deposit message described under
                    Settlement Procedure "C" below in order to include the
                    amount of any interest payable and certain other information
                    regarding the related Global Security in the appropriate
                    weekly bond report published by Standard & Poor's
                    Corporation.

                    Record Dates.  The Record Date with respect to any Interest
                    Payment Date will be the date fifteen calendar days
                    immediately preceding such Interest Payment Date.

                    Fixed Rate Book-Entry Notes.  Unless otherwise specified
                    pursuant to Settlement Procedure "A" below, interest
                    payments on Fixed Rate Book-Entry Notes [, other than
                    Amortizing Notes,] will be made semiannually on
                    _____________ ___ and _____________ ___ of each year, and at
                    maturity or upon any earlier redemption or repayment [and
                    principal and interest payments on Book-Entry Amortizing
                    Notes will be made semiannually on __________ __ and
                    __________ __ of each year or quarterly on __________ __,
                    __________ __, __________ __ and __________ __ of each year,
                    and at maturity (or on any redemption or repayment date)];
                    provided, however, that in the case of a Fixed Rate Book-
                    Entry Note issued between a Record Date and an Interest
                    Payment Date or on an Interest Payment Date, the first
                    interest payment will be made on the Interest Payment Date
                    following the next succeeding Record Date.  If any Interest
                    Payment Date for a Fixed Rate Book-Entry Note is not a
                    Business Day, the payment due on such day will be made on
                    the next succeeding Business

                                      -5-

                    Day and no interest will accrue on such payment for the
                    period from and after such Interest Payment Date.

                    Floating Rate Book-Entry Notes.  Interest payments will be
                    made on Floating Rate Book-Entry Notes monthly, quarterly,
                    semiannually or annually.  Unless otherwise specified
                    pursuant to Settlement Procedure "A" below, interest will be
                    payable, in the case of Floating Rate Book-Entry Notes with
                    a daily, weekly or monthly Interest Reset Date, on the third
                    Wednesday of each month or on the third Wednesday of
                    __________, __________, __________ and __________, as
                    specified pursuant to Settlement Procedure "A" below; in the
                    case of Floating Rate Book-Entry Notes with a quarterly
                    Interest Reset Date, on the third Wednesday of ____________,
                    __________, _________ and ___________ of each year; in the
                    case of Floating Rate Book-Entry Notes with a semiannual
                    Interest Reset Date, on the third Wednesday of the two
                    months specified pursuant to Settlement Procedure "A" below;
                    and in the case of Floating Rate Book-Entry Notes with an
                    annual Interest Reset Date, on the third Wednesday of the
                    month specified pursuant to Settlement Procedure "A" below;
                    provided however, that if an Interest Payment Date for
                    Floating Rate Book-Entry Notes would otherwise be a day that
                    is not a Business Day with respect to such Floating Rate
                    Book-Entry Notes, such Interest Payment Date will be the
                    next succeeding Business Day with respect to such Floating
                    Rate Book-Entry Notes, except in the case of a LIBOR Note
                    and such Business Day is in the next succeeding calendar
                    month, in which case such Interest Payment Date will be the
                    immediately preceding Business Day; and provided, further,
                    that in the case of a Floating Rate Book-Entry Note issued
                    between a Record Date and the related Interest Payment Date
                    (a "Book-Entry Gap Note"), the first interest payment will
                    be made on the Interest Payment Date following the next
                    succeeding Record Date, and in such case notwithstanding the
                    fact that an Interest Reset Date may occur prior to such
                    Interest Payment Date, the Initial Interest Rate will remain
                    in effect until the first Interest Reset Date occurring on
                    or subsequent to such Interest Payment Date.

                    Notice of Interest Payment and Record Dates.  On the first
                    Business Day of __________, __________, __________ and
                    __________ of each year, the Trustee will deliver to the
                    Company and DTC a written list of Record Dates and Interest
                    Payment Dates that will occur with respect to Book-Entry
                    Notes during the six-month period beginning on such first
                    Business Day.  Promptly after each date upon which interest
                    is determined for Floating Rate Notes issued in book-entry
                    form,

                    the Calculation Agent will notify the Company, the Trustee
                    and Standard & Poor's Corporation of the interest rates
                    determined on such dates.

Calculation of      Fixed Rate Book-Entry Notes.  Interest on Fixed Rate
Interest:           Book-Entry Notes (including interest for partial periods)
                    will be calculated on the basis of a year of twelve thirty-
                    day months.

                    Floating Rate Book-Entry Notes.  Interest rates on Floating
                    Rate Book-Entry Notes will be determined as set forth in the
                    form of such Notes.  Interest on Floating Rate Book-Entry
                    Notes will be calculated on the basis of actual days elapsed
                    and a year of 360 days, except that, in the case of Treasury
                    Rate Notes, interest will be calculated on the basis of the
                    actual number of days in the year.

Payments of         Payments of Interest Only.  Promptly following each Record
Principal and       Date, the Trustee will deliver to the Company and DTC a
Interest:           written notice specifying by CUSIP number the amount of
                    interest to be paid on each Global Security other than an
                    Amortizing Note on the following Interest Payment Date
                    (other than an Interest Payment Date coinciding with
                    maturity or earlier redemption or repayment) and the total
                    of such amounts. DTC will confirm the amount payable on each
                    such Global Security on such Interest Payment Date by
                    reference to the daily bond reports published by Standard &
                    Poor's Corporation.  In the case of Amortizing Notes, the
                    Trustee will provide separate written notice to the Company
                    and to DTC prior to each Interest Payment Date at the time
                    and in the manner set forth in the Letter of Representation.
                    The Company will pay to the Trustee, as paying agent, the
                    total amount of interest due on such Interest Payment Date
                    (and, in the case of an Amortizing Note, principal and
                    interest) (other than at maturity), and the Trustee will pay
                    such amount to DTC at the times and in the manner set forth
                    below under "Manner of Payment."

                    Payments at Maturity or Upon Redemption or Repayment.  On or
                    about the first Business Day of each month, the Trustee will
                    deliver to the Company and DTC a written list of principal
                    and interest to be paid on each Global Security other than
                    an Amortizing Note maturing either at maturity or on a
                    redemption or repayment date in the following month.  The
                    Company and DTC will confirm the amounts of such principal
                    and interest payments with respect to each such Global
                    Security on or about the fifth Business Day preceding the
                    Maturity Date or redemption or repayment date of such Global
                    Security.  In the case of Amortizing Notes, the Trustee will
                    provide separate

                                      -7-
<PAGE>
  
                    written notice to the Company and to DTC prior to the
                    Maturity Date and any redemption or repayment date, as the
                    case may be, at the times and in the manner set forth in the
                    Letter of Representation.  The Company will pay to the
                    Trustee, as the paying agent, the principal amount of such
                    Global Security, together with interest due at such Maturity
                    Date or redemption or repayment date.  The Trustee will pay
                    such amounts to DTC at the times and in the manner set forth
                    below under "Manner of Payment."

                    Payments Not on Business Days.  If any Interest Payment Date
                    or the Maturity Date or redemption or repayment date of a
                    Global Security representing Fixed Rate Book-Entry Notes is
                    not a Business Day, the payment due on such day will be made
                    on the next succeeding Business Day and no interest will
                    accrue on such payment for the period from and after such
                    Interest Payment Date, Maturity Date or redemption or
                    repayment date, as the case may be.  If any Interest Payment
                    Date or the Maturity Date or redemption or repayment date of
                    a Global Security representing a Floating Rate Book-Entry
                    Note would otherwise fall on a day that is not a Business
                    Day, the payment due on such day will be made on the next
                    succeeding day that is a Business Day with respect to such
                    Notes with the same effect as if such Business Day were the
                    Interest Payment Date, Maturity Date or date of redemption
                    or repayment, as the case may be, except that, in the case
                    of Book-Entry LIBOR Notes, if such Business Day is in the
                    next succeeding calendar month, such Interest Payment Date,
                    Maturity Date or redemption or repayment date will be the
                    immediately preceding day that is a Business Day with
                    respect to such Book-Entry LIBOR Notes.  Promptly after
                    payment to DTC of the principal and interest due on the
                    Maturity Date or redemption or repayment date of a Global
                    Security, the Trustee will cancel such Global Security in
                    accordance with the terms of the Indenture and deliver it to
                    the Company with a certificate of cancellation.  [Upon
                    request/ On the first Business Day of each month], the
                    Trustee will deliver to the Company a written statement
                    indicating the total principal amount of outstanding Book-
                    Entry Notes as of the immediately preceding Business Day.

                    Manner of Payment.  The total amount of any principal and
                    interest due on Global Securities on any Interest Payment
                    Date or at maturity or upon redemption or repayment will be
                    paid by the Company to the Trustee in funds available for
                    immediate use by the Trustee as of 9:30 a.m. (New York City
                    time) on such date.  The Company will make such payment on
                    such Global Securities by wire transfer to the Trustee or by
                    instructing the

                                      -8-

                    D.   The Trustee will complete and authenticate the Global
                         Security representing such Note in accordance with the

                    G.   Unless the relevant Agent purchased such Note as
                         principal, such Agent will enter an SDFS deliver order

                         DTC (i) to debit such Note to such Agent's participant
                         account and credit such Note to the participant account
                         of the Participant with respect to such Note and (ii)

                    H.   Transfers of funds in accordance with SDFS deliver
                         orders described in Settlement Procedures "F" and "G"
                         will be settled in accordance with SDFS operating

                         Trustee from time to time, in funds available for
                         immediate use in the amount transferred to the Trustee,
                         in accordance with Settlement Procedure "F".

                    J.   Unless the relevant Agent purchased such Note as
                         principal, such Agent will confirm the purchase of such
                         Note to the purchaser either by transmitting to the
                         Participant with respect to such Note a confirmation

                    in the SDFS operating procedures in effect on the settlement
                    date.  If settlement of a Book-Entry Note is rescheduled or

                    withdrawal message instructing DTC to debit such Note to the
                    Trustee's participant account; provided, that the Trustee's
                    participant account contains a principal amount of the
                    Global Security representing such Note that is at least
                    equal to the principal amount to be debited.  If a
                    withdrawal message is processed with respect to all the
                    Book-Entry Notes represented by a Global Security, the
                    Trustee will mark such Global Security "canceled," make
                    appropriate entries in the Trustee's records and send such
                    canceled Global Security to the Company.  The CUSIP number
                    assigned to such Global Security will, in accordance with
                    CUSIP Service Bureau procedures, be canceled and not
                    immediately reassigned.  If a withdrawal message is
                    processed with respect to one or more, but not all, of the
                    Book-Entry Notes represented by a Global Security, the
                    Trustee will exchange such Global Security for two Global
                    Securities, one of which will represent such Book-Entry Note
                    or Notes and will be canceled immediately after issuance and
                    the other of which will represent the remaining Book-Entry
                    Notes previously represented by the surrendered Global
                    Security and will bear the CUSIP number of the surrendered
                    Global Security.

                    If the purchase price for any Book-Entry Note is not timely
                    paid to the Participant with respect to such Note by the
                    beneficial purchaser thereof (or a person, including an
                    indirect participant in DTC, acting on behalf of such
                    purchaser), such Participant and, in turn, the relevant
                    Agent may enter SDFS deliver orders through DTC's
                    Participant Terminal System reversing the orders entered
                    pursuant to Settlement Procedures "F" and "G", respectively.
                    Thereafter, the Trustee will deliver the withdrawal message
                    and take the related actions described in the preceding
                    paragraph.

                    Notwithstanding the foregoing, upon any failure to settle
                    with respect to a Book-Entry Note, DTC may take any action
                    in accordance with its SDFS operating procedures then in
                    effect.

                    In the event of a failure to settle with respect to one or
                    more, but not all, of the Book-Entry Notes to have been
                    represented by a Global Security, the Trustee will provide,
                    in accordance with Settlement Procedures "D" and "F", for
                    the authentication and issuance of a Global Security
                    representing the Book-Entry Notes to be represented by such
                    Global Security and will make appropriate entries in its
                    records.

Posting Rates by    The Company and the Agents will discuss from time to time
Company:            the rates of interest per annum to be borne by and the
                    maturity of Securities that may be sold as a result of the
                    solicitation of offers by an Agent. The Company may
                    establish a fixed set of interest rates and maturities for
                    an offering period ("posting"). If the Company decides to
                    change already posted rates, it will promptly advise the
                    Agents to suspend solicitation of offers until the new
                    posted rates have been established with the Agents.

Trustee Not To      Nothing herein will be deemed to require the Trustee to
Risk Funds:         risk or expend its own funds in connection with any payments
                    to the Company, the Agents, DTC or any holders of Notes, it
                    being understood by all parties that payments made by the
                    Trustee to the Company, the Agents, DTC or any holders of
                    Notes will be made only to the extent that funds are
                    provided to the Trustee for such purpose.


          PART II:  ADMINISTRATIVE PROCEDURES FOR CERTIFICATED NOTES

          The Trustee will serve as registrar in connection with the
Certificated Notes.

Issuance:           Each Certificated Note will be dated and issued as of the
                    date of its authentication by the Trustee.  Each
                    Certificated Note will bear an Original Issue Date, which
                    will be (i) with respect to an original Certificated Note
                    (or any portion thereof), its original issuance date (which
                    will be the settlement date) and (ii) with respect to any
                    Certificated Note (or any portion thereof) issued
                    subsequently upon exchange of a Certificated Note, or in
                    lieu of a destroyed, lost or stolen Certificated Note, the
                    original issuance date of the predecessor Certificated Note,
                    regardless of the date of authentication of such
                    subsequently issued Certificated Note.  [No Note issued
                    between a Record Date and the related Interest Payment Date
                    will be issued as a Certificated Note within the meaning of
                    the Indenture.]

Exchanges:          exchange at the principal corporate trust office of the
                    Trustee.  Certificated Notes will be exchangeable for other
                    Certificated Notes having identical terms but different
                    authorized denominations without service charge.
                    Certificated Notes will not be exchangeable for Book-Entry
                    Notes.

Maturities:         Each Certificated Note will mature on a date from nine
                    months to [30] years from its date of issue.

Currency:           The currency denomination with respect to any Certificated
                    Note and the currency of payment of interest and principal
                    with respect to any such Certificated Note will be as set
                    forth therein and in the applicable Pricing Supplement.

Denominations:      Unless otherwise provided in a Prospectus Supplement, the
                    denomination of any Certificated Note will be a minimum of
                    $__________ (or in the case of Notes not denominated in U.S.
                    dollars, the equivalent thereof in the applicable foreign
                    currency or composite currency, rounded down to the nearest
                    1,000 units of such foreign currency or composite currency)
                    or any amount in excess thereof that is an integral multiple
                    of $1,000 (or in the case of Notes not denominated in U.S.
                    dollars, 1,000 units of such foreign currency or composite
                    currency).

Interest:           General.  Interest on each Certificated Note will accrue
                    from the Original Issue Date of such Note for the first
                    interest period and from the most recent date to which
                    interest has been paid for all subsequent interest periods.
                    Unless otherwise specified therein, each payment of interest
                    on a Certificated Note will include interest accrued to but
                    excluding the Interest Payment Date; provided, that in the
                    case of Floating Rate Notes with respect to which the
                    Interest Reset Period is daily or weekly, interest payable
                    on any Interest Payment Date (other than interest payable on
                    any date on which principal thereof is payable, and, if the
                    Note is a Certificated Gap Note (as defined below), other
                    than interest payable on the first Interest Payment Date
                    after the Original Issue Date thereof) will include interest
                    accrued through and including the Record Date immediately
                    preceding the Interest Payment Date, except that at maturity
                    or earlier redemption or repayment, the interest payable
                    will include interest accrued to, but excluding, the
                    Maturity Date or the date of redemption or repayment, as the
                    case may be.

                    Record Dates.  The Record Date with respect to any Interest
                    Payment Date in respect of a Certificated Note will be the
                    date fifteen calendar days immediately preceding such
                    Interest Payment Date.

                    Fixed Rate Certificated Notes.  Unless otherwise specified
                    pursuant to Settlement Procedure "A" below, interest
                    payments on Fixed Rate Certificated Notes, other than
                    Amortizing Notes, will be made semiannually on
                    _______________ ___ and _______________ ___ of each year (or
                    if so indicated in such Note, annually on _______________ __
                    of each year), and at maturity or upon any earlier
                    redemption or repayment and principal and interest payments
                    on Amortizing Certificated Notes will be made semiannually
                    on _______________ __ and _______________ __ of each year or
                    quarterly on _______________ __, _______________ __,
                    _______________ __  and _______________ __ of each year, and
                    at maturity (or on any redemption or repayment date);
                    provided, however, that in the case of a Fixed Rate
                    Certificated Note issued between a Record Date and an
                    Interest Payment Date or on an Interest Payment Date, the
                    first interest payment will be made on the Interest Payment
                    Date following the next succeeding Record Date.

                    Floating Rate Certificated Notes.  Interest payments will be
                    made on Floating Rate Certificated Notes monthly, quarterly,
                    semiannually or annually.  Unless otherwise specified
                    pursuant to Settlement Procedure "A" below, interest will be
                    payable, in the case of Floating Rate Certificated Notes
                    with a daily, weekly or monthly Interest Reset Date, on the
                    third Wednesday of each month or on the third Wednesday of
                    _______________, _______________, _______________ and
                    _______________, as specified pursuant to Settlement
                    Procedure "A" below; in the case of Floating Rate
                    Certificated Notes with a quarterly Interest Reset Date, on
                    the third Wednesday of _______________, _______________,
                    _______________ and _______________ of each year; in the
                    case of Floating Rate Certificated Notes with a semiannual
                    Interest Reset Date, on the third Wednesday of the two
                    months specified pursuant to Settlement Procedure "A" below;
                    and in the case of Floating Rate Certificated Notes with an
                    annual Interest Reset Date, on the third Wednesday of the
                    month specified pursuant to Settlement Procedure "A" below;
                    provided, however, that if an Interest Payment Date for
                    Floating Rate Certificated Notes would otherwise be a day
                    that is not a Business Day with respect to such Floating
                    Rate Certificated Notes, such Interest Payment Date will be
                    the next succeeding Business Day with respect to such
                    Floating Rate Certificated

                    Notes, except in the case of a LIBOR Note and such Business
                    Day is in the next succeeding calendar month, in which case
                    such Interest Payment Date will be the immediately preceding
                    Business Day; and provided, further, that in the case of a
                    Floating Rate Certificated Note issued between a Record Date
                    and the related Interest Payment Date (a "Certificated Gap
                    Note"), the first interest payment will be made on the
                    Interest Payment Date following the next succeeding Record
                    Date, and in such case, notwithstanding the fact that an
                    Interest Reset Date may occur prior to such Interest Payment
                    Date, the Initial Interest Rate will remain in effect until
                    the first Interest Reset Date occurring on or subsequent to
                    such Interest Payment Date.

                    Notice of Interest Payment and Record Dates.  On the first
                    Business Day of _______________, _______________,
                    _______________ and _______________ of each year, the
                    Trustee will deliver to the Company a written list of Record
                    Dates and Interest Payment Dates that will occur with
                    respect to Certificated Notes during the six-month period
                    beginning on such first Business Day.  Promptly after each
                    date upon which interest is determined for Floating Rate
                    Notes issued in certificated form, the Calculation Agent
                    will notify the Company and the Trustee of the interest
                    rates determined on such dates.

Calculation of      Fixed Rate Certificated Notes.  Interest on Fixed Rate
Interest:           Certificated Notes (including interest for partial periods)
                    will be calculated on the basis of a year of twelve thirty-
                    day months.

                    Floating Rate Certificated Notes.  Interest rates on
                    Floating Rate Certificated Notes will be determined as set
                    forth in the form of such Notes.  Interest on Floating Rate
                    Certificated Notes will be calculated on the basis of actual
                    days elapsed and a year of 360 days, except that, in the
                    case of Treasury Rate Notes, interest will be calculated on
                    the basis of the actual number of days in the year.

Payments of         The Company will pay the Trustee, as paying agent, the
Principal and       principal amount of each Certified Note (other than the
Interest:           interest on an Amortizing Note), together with interest due
                    thereon, at its Maturity Date or upon redemption or
                    repayment of such Note in funds available for immediate use
                    by the Trustee. In the case of an Amortizing Note, the
                    Company will pay the Trustee, as paying agent, the principal
                    amount due on such Note on such date, together with interest
                    due thereon, at its Maturity Date or upon redemption or
                    repayment of such Note on such date in funds available for
                    immediate use by the Trustee. The Trustee will pay such
                    amount to the holder of such Note at its Maturity

                                      -18-

                    Date or upon redemption or repayment of such Note upon
                    presentation and surrender of such Note to the Trustee.
                    Such payment, together with payment of interest due at
                    maturity or upon redemption or repayment, will be made in
                    funds available for immediate use by the holder of such
                    Note.  Promptly after such presentation and surrender, the
                    Trustee will cancel such Certificated Note in accordance
                    with the terms of the Indenture and deliver it to the
                    Company with a certificate of cancellation.  Unless
                    otherwise specified in the applicable Pricing Supplement,
                    all interest payments on a Certificated Note or, in the case
                    of an Amortizing Certificated Note, payments of principal
                    and interest (other than interest (or interest and
                    principal) due at maturity or upon redemption or repayment)
                    will be made by check drawn on the Trustee (or another
                    person appointed by the Trustee) and mailed by the Trustee
                    to the person entitled thereto as provided in such Note and
                    the Indenture; provided, however, that (i) the holder of
                    $___________ or more of Notes having the same Interest
                    Payment Date will be entitled to receive payment by wire
                    transfer of immediately available funds and (ii) unless
                    otherwise specified in the applicable Pricing Supplement or
                    unless alterative arrangements are made, payments on Notes
                    in a currency other than U.S. dollars will be made by wire
                    transfer of immediately available funds to an account
                    maintained by the payee with a bank located outside the
                    United States and, with respect to clauses (i) and (ii)
                    above, the holder of such Notes will provide the Trustee
                    with appropriate and timely wire transfer instructions.

                    Promptly after each Record Date, the Trustee will deliver to
                    the Company a written notice specifying the amount of
                    interest to be paid on each Certificated Note other than an
                    Amortizing Note on the following Interest Payment Date
                    (other than an Interest Payment Date coinciding with
                    maturity or any earlier redemption or repayment date) and
                    the total of such amounts.  In the case of Amortizing Notes,
                    the Trustee will provide separate written notice to the
                    Company specifying the amount of interest and principal to
                    be paid on each Amortizing Note on the following Interest
                    Payment Date (other than an Interest Payment Date coinciding

                    be made on the next succeeding Business Day and no interest
                    will accrue on such payment for the period from and after

                    the payment due on such day will be made on the next

                    stated Interest Payment Date, Maturity Date or date of
                    redemption or repayment, as the case may be, except that, in
                    the case of Certificated LIBOR Notes, if such Business Day
                    is in the next succeeding calendar month, such Interest
                    Payment Date, Maturity Date or redemption or repayment date
                    will be the immediately preceding day that is a Business 
                    Day with respect to such Certificated LIBOR Notes.

                    maturity of Securities that may be sold as a result of the
                    solicitation of offers by an Agent. The Company may
                    establish a fixed set of interest rates and maturities for
                    an offering period ("posting"). If the Company decides to
                    change already posted rates, it will promptly advise the
                    Agents to suspend solicitation of offers until the new
                    posted rates have been established with the Agents.

                    made only to the extent that funds are provided to the
                    Trustee for such purpose.

     express an informed opinion as to whether or not such covenant or condition

          (4) a statement as to whether, in the opinion of each such individual,

          In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

          Any certificate or opinion of an officer of the Company may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous.  Any such certificate or opinion of counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows, or in the exercise of reasonable care should
know, that the certificate or opinion or representations with respect to such
matters are erroneous.

instruments under this Indenture, they may, but need not, be consolidated and

SECTION 104.   Acts of Holders; Record Dates.
               ----------------------------- 

          (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agents duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company.  Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments.  Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

          (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof.  Where
such execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority.  The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

          (c) The Company may, in the circumstances permitted by the Trust
Indenture Act, fix any day as the record date for the purpose of determining the
Holders of Securities of any series entitled to give or take any request,
demand, authorization, direction, notice, consent, waiver or other action, or to
vote on any action, authorized or permitted to be given or taken by Holders of
Securities of such series.  If not set by the Company prior to the first
solicitation of a Holder of Securities of any series made by any Person in
respect of any such action, or, in the case of any such vote, prior to such
vote, the record date for any such action or vote shall be the 3Oth day (or, if
later, the date of the most recent list of Holders of Securities of such series
required to be provided pursuant to Section 701) prior to such first
solicitation or vote, as the case may be.  With regard to any record date for
action to be taken by the Holders of one

                                     -10-
<PAGE>
 
or more series of Securities, only the Holders of Securities of such series on
such date (or their duly designated proxies) shall be entitled to give or take,
or vote on, the relevant action.  Notwithstanding the foregoing, the Company
shall not set a record date for, and the provisions of this paragraph shall not
apply with respect to, any Act by the Holders pursuant to Section 501, 502 or
512.

          (d) The ownership of Securities shall be proved by the Security
Register.

          (e) Any Act of the Holder of any Security shall bind every future
Holder of the same Security and the Holder of every Security issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee or the
Company in reliance thereon, whether or not notation of such action is made upon
any such Security.

          (f) Without limiting the foregoing, a Holder entitled hereunder to
give or take any action hereunder with regard to any particular Security may do
so with regard to all or any part of the principal amount of such Security or by
one or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any different part of such principal amount.

SECTION 105.   Notices, Etc., to Trustee and Company.
               ------------------------------------- 

          Any Act of Holders or other document provided or permitted by this
Indenture to be made upon, given or furnished to, or filed with,

          (1) the Trustee by any Holder or by the Company shall be sufficient
     for every purpose hereunder if made, given, furnished or filed in writing
     to or with the Trustee at its Corporate Trust Office, Attention: Corporate
     Trust Department, including via facsimile transmission to (212) 701-7684,
     or

          (2) the Company by the Trustee or by any Holder shall be sufficient
     for every purpose hereunder (unless otherwise herein expressly provided) if
     in writing and mailed, first-class postage prepaid, to the Company 
     addressed to it, Attention: __________________, at the address of its
     principal executive offices specified in the first paragraph of this
     instrument or at any other address previously furnished in writing to the
     Trustee by the Company or via facsimile transmission to (412) ___-____.

SECTION 106.   Notice to Holders; Waiver.
               ------------------------- 

          Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice.  In any case where notice to Holders
is given by mail, neither the failure to mail any notice, nor any defect in any
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders.  Where this Indenture provides for notice
in any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice.  Waivers of notice by Holders shall be filed with
the Trustee, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

          In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

SECTION 107.   Conflict With Trust Indenture Act.
               --------------------------------- 

          If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be a
part of and govern this Indenture, the latter provision shall control.  If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture only as so modified or excluded, as the case
may be.

SECTION 108.   Effect of Headings and Table of Contents.
               ---------------------------------------- 

          The Article and Section headings herein and the Table of Contents are

               ---------------------- 

          All covenants and agreements in this Indenture by the Company shall
bind or inure to the benefit of its successors and assigns, whether so expressed
or not.

SECTION 110.   Separability Clause.
               ------------------- 

          In case any provision in this Indenture or in the Securities shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 111.   Benefits of Indenture.
               --------------------- 

          Nothing in this Indenture or in the Securities, express or implied,

hereunder, any Security Registrar, any Paying Agent, any Authenticating Agent
and the Holders, any benefit or any legal or equitable right, remedy or claim

to the conflicts of law rules of said Commonwealth; provided, however, that the
rights, duties and  obligations of, and the standard of care for, the Trustee
shall be governed by the laws of the State of New York, without regard to the
conflicts of law rules of said State.

SECTION 113.   Legal Holidays.
               -------------- 

          In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the Securities
(other than a provision of the Securities of any series that specifically states
that such provision shall apply in lieu of this Section)) payment of interest or
principal (and premium, if any) need not be made at such Place of Payment on
such date, but may be made on the next succeeding Business Day at such Place of
Payment with the same force and effect as if made on the Interest Payment Date
or Redemption Date or at the Stated Maturity; provided, that no interest shall
accrue for the period from and after such Interest Payment Date, Redemption Date
or Stated Maturity, as the case may be, to such Business Day if such payment is
made or duly provided for on such Business Day.

SECTION 114.   No Security Interest Created.
               ---------------------------- 

          Nothing in this Indenture or in any Securities, express or implied,

Commercial Code or similar legislation, as now or hereafter enacted and in

Company or any successor Person, either directly or through the Company, whether

of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company

future Holders of this Security and of any Security issued upon the registration
of transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

          No reference herein to the Indenture and no provision of this Security

premium and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Securities of
this series and of like tenor, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.

          The Securities of this series are issuable only in registered form
without coupons in denominations of $1,000 and any integral multiple thereof.
As provided in the Indenture and subject to certain limitations therein set
forth, Securities of this series are exchangeable for a like aggregate principal
amount of Securities of like tenor of a different authorized denomination, as
requested by the Holder surrendering the same.

any tax or other governmental charge payable in connection therewith.

          Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner

multiple thereof except as otherwise

                                     -23-
<PAGE>
 
specified as contemplated by Section 301.  Securities shall be numbered,
lettered or otherwise distinguished in such manner or in accordance with such
plan as the officers of the Company executing the same may determine with the
approval of the Trustee.

SECTION 303.   Execution, Authentication, Delivery and Dating.
               ---------------------------------------------- 

          The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its Vice Chairman of the Board, if any, its President or
one of its Vice Presidents, under its corporate seal or a facsimile thereof
reproduced thereon attested by its Secretary or one of its Assistant
Secretaries.  The signature of any of these officers on the Securities may be
manual or facsimile.

          Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

          At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall either at one time or from time to time pursuant to
such instructions as may be described therein authenticate and deliver such
Securities.  If the form or terms of the Securities of the series have been
established in or pursuant to one or more Board Resolutions as permitted by
Sections 201 and 301, in authenticating such Securities, and accepting the
additional responsibilities under this Indenture in relation to such Securities,
the Trustee shall be entitled to receive, and (subject to Section 601) shall be
fully protected in relying upon, an Opinion of Counsel stating,

          (a) if the form of such Securities has been established by or pursuant
     to Board Resolution as permitted by Section 201, that such form has been
     established in conformity with the provisions of this Indenture;

          (b) if the terms of such Securities have been established by or
     pursuant to Board Resolution as permitted by Section 301, that such terms
     have been established in conformity with the provisions of this Indenture;
     and

          (c) that such Securities, when authenticated and delivered by the
     Trustee and issued by the Company in the manner and subject to any
     conditions specified in such

                                     -24-
<PAGE>
 
     Opinion of Counsel, will constitute valid and legally binding obligations
     of the Company enforceable in accordance with their terms, subject to
     bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
     similar laws of general applicability relating to or affecting creditors'
     rights and to general equity principles.

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

          Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the time
of authentication of each Security of such series if such documents are
delivered at or prior to the authentication upon original issuance of the first
Security of such series to be issued.

          Each Security shall be dated the date of its authentication.

          No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein duly
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder and is entitled to the
benefits of this Indenture.  Notwithstanding the foregoing, if any Security
shall have been authenticated and delivered hereunder but never issued and sold
by the Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided in Section 309, for all purposes of this Indenture such
Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.

          If the Securities are to be issued in whole or in part in the form of
one or more Global Securities, then the Company shall execute and the Trustee
shall authenticate and deliver one or more Global Securities that (i) shall
represent an aggregate amount equal to the aggregate principal amount of the
Outstanding Securities to be represented by one or more Global Securities, (ii)
shall be registered in the name of the Depositary for such Global Security or
Securities or the nominee of such Depositary,

                                     -25-
<PAGE>
 
(iii) shall be delivered by the Trustee to such Depositary or pursuant to such
Depositary's instruction and (iv) shall bear a legend substantially to the
following effect (or in the form required by such Depositary): "Unless and until
it is exchanged in whole or in part for the individual Securities represented
hereby, this Global Security may not be transferred except as a whole by the
Depositary to a nominee of the Depositary or by a nominee of the Depositary to
the Depositary or another nominee of the Depositary or by the Depositary or any
such nominee to a successor Depositary or a nominee of such successor
Depositary."

          Each Depositary for a Global Security must, at all times while it
serves as such Depositary, be a clearing agency registered under the Securities
Exchange Act of 1934, as amended, and any other applicable statute or
regulation.

SECTION 304.   Temporary Securities.
               -------------------- 

          Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities.  Any such temporary Security
may be in global form, representing all or a portion of the Outstanding
Securities.  Every such temporary Security shall be executed by the Company and
shall be authenticated and delivered by the Trustee upon the same conditions and
in substantially the same manner, and with the same effect, as the definitive
Security or Securities in lieu of which it is issued.

          If temporary Securities of any series are issued, the Company will
cause definitive Securities of such series to be prepared without unreasonable
delay.  After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary Securities of such
series at the office or agency of the Company in a Place of Payment for such
series, without charge to the Holder.  Upon surrender for cancellation of any
one or more temporary Securities of any series, the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor one or more
definitive Securities of the same series of a like aggregate principal amount in
authorized denominations.  Until so exchanged the temporary Securities of any
series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of such series.

          Upon any exchange of a portion of a temporary Global Security for a
definitive Global Security or for the individual Securities represented thereby
pursuant to this Section 304 or Section 305, the temporary Global Security shall
be endorsed by the Trustee to reflect the reduction of the principal amount
evidenced thereby, whereupon the principal amount of such temporary Global
Security shall be reduced for all purposes by the amount so exchanged and
endorsed.

SECTION 305.   Registration; Registration
               of Transfer and Exchange.
               ------------------------ 

          (a) The Company shall cause to be kept at the Corporate Trust Office
of the Trustee a register (the register maintained in such office and in any
other office or agency of the Company in a Place of Payment being herein
sometimes collectively referred to as the "Security Register") in which, subject
to such reasonable regulations as it may prescribe, the Company shall provide
for the registration of Securities and of transfers and exchanges of Securities.
The Trustee is hereby appointed "Security Registrar" for the purpose of
registering Securities and transfers and exchanges of Securities as herein
provided.  At all reasonable times, upon reasonable notice, the Security
Register shall be open for inspection by the Company.

          Upon surrender for registration of transfer of any Security of any
series, at the office or agency in a Place of Payment for such series, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of
the same series of any authorized denominations and of a like aggregate
principal amount.

          Notwithstanding any other provision of this Section, unless and until
it is exchanged in whole or in part for the individual Securities represented
thereby, a Global Security representing all or a portion of the Securities of
any series may not be transferred except as a whole by the Depositary to a
nominee of such Depositary or by a nominee of such Depositary to such Depositary
or another nominee of such Depositary or by such Depositary or any such nominee
to a successor Depositary or a nominee of such successor Depositary.

          At the option of the Holder, Securities of any series may be exchanged
for other Securities of the same series of any authorized denominations and of a
like aggregate principal amount, upon surrender of the Securities to be
exchanged at the office or agency maintained for that purpose for such series.
Whenever any Securities are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Securities which
the Holder making the exchange is entitled to receive.

                                     -27-
<PAGE>
 
          (b) If at any time the Depositary for the Securities of any series
notifies the Company that it is unwilling or unable to continue as Depositary
for the Securities of such series or if at any time the Depositary for the
Securities of any series shall no longer be eligible under Section 303, the
Company shall appoint a successor Depositary.  If a successor Depositary for the
Securities of any series is not appointed by the Company within 90 days after
the Company receives such notice or becomes aware of such ineligibility, the
Company will execute, and the Trustee, upon receipt of a Company Order for the
authentication and delivery of individual Securities of such series, will
authenticate and deliver, individual Securities of such series in an aggregate
principal amount equal to the principal amount of the Global Security or
Securities representing such Securities in exchange for such Global Security or
Securities.

          The Company may at any time and in its sole discretion determine that
individual Securities of any series issued in the form of one or more Global
Securities shall no longer be represented by such Global Security or Securities.
In such event, or if an Event of Default has occurred and is continuing with
respect to such series, the Company will execute, and the Trustee, upon receipt
of a Company Order for the authentication and delivery of individual Securities
of such series, will authenticate and deliver, individual Securities of such
series in an aggregate principal amount equal to the principal amount of the
Global Security or Securities representing the Securities of such series in
exchange for such Global Security or Securities.

          The Depositary for the Securities of any series may surrender a Global
Security in exchange in whole or in part for individual Securities of such
series on such terms as are acceptable to the Company and such Depositary.
Thereupon, the Company shall execute, and the Trustee shall authenticate and
deliver, without service charge,

          (i) to each Person specified by the Depositary a new individual
     Security or Securities of such series of any authorized denomination as
     requested by such Person in aggregate principal amount equal to and in
     exchange for such Person's beneficial interest in the Global Security; and

          (ii) to the Depositary a new Global Security in a denomination equal
     to the difference, if any, between the principal amount of the surrendered
     Global Security and the aggregate principal amount of individual Securities
     of such series delivered to Holders thereof.

          Upon the exchange of a Global Security for individual Securities of
any series, such Global Security shall be canceled by the Trustee.  Individual
Securities of such series issued in exchange for a Global Security pursuant to
this Section shall be

                                     -28-
<PAGE>
 
registered in such names and in such authorized denominations as the Depositary
for such Global Security, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee.  The Trustee shall
deliver such Securities to the Persons in whose names such Securities are so
registered.

          (c) All Securities issued upon any registration of transfer or
exchange of Securities shall be the valid obligations of the Company, evidencing
the same debt, and entitled to the same benefits under this Indenture, as the
Securities surrendered upon such registration of transfer or exchange.

          Every Security presented or surrendered for registration of transfer
or for exchange shall (if so required by the Company or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

          No service charge shall be made for any registration of transfer or
exchange of Securities except as provided in Section 306.  The Company may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer or
exchange of Securities, other than exchanges pursuant to Section 304, 906 or
1107 not involving any transfer.

          The Company shall not be required (i) to issue, register the transfer
of or exchange Securities of any series during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of redemption of
Securities of such series selected for redemption under Section 1103 and ending
at the close of business on the day of such mailing, or (ii) to register the
transfer of or exchange any Security so selected for redemption in whole or in
part, except the unredeemed portion of any Security being redeemed in part.

SECTION 306.   Mutilated, Destroyed, Lost and Stolen Securities.
               ------------------------------------------------ 

          If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

          If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
and (ii) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of notice to
the Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and the Trustee

                                     -29-
<PAGE>
 
shall authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

          In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

          Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including, without limitation, the fees and expenses of the Trustee)
connected therewith.

          Every new Security of any series issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities of such series duly issued hereunder.

          The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities.

SECTION 307.   Payment of Interest; Interest Rights Preserved.
               ---------------------------------------------- 

          Except as otherwise provided as contemplated by Section 301 with
respect to any series of Securities, interest on any Security which is payable,
and is punctually paid or duly provided for, on any Interest Payment Date shall
be paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.  Except as otherwise provided as contemplated by Section 301
with respect to any series of Securities, at the option of the Company, interest
on Securities of any series will be paid by mailing checks to the addresses of
the Holders thereof as such addresses shall appear in the Securities Register if
such Securities are not represented by a Global Security and interest on any
Global Security will be paid by wire transfer of immediately available funds to
an account designated by the Depositary.

          Any interest on any Security of any series which is payable, but is
not punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall

                                     -30-
<PAGE>
 
forthwith cease to be payable to the 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 (2)
below:

          (1) The Company may elect to make payment of any Defaulted Interest to
     the Persons in whose names the Securities of such series (or their
     respective Predecessor Securities) 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 as to the amount of Defaulted Interest proposed to be
     paid on each Security of such series and the date of the proposed payment,
     and at the same time the Company shall deposit with the Trustee an amount
     of money equal to the aggregate amount proposed to be paid in respect of
     such Defaulted Interest or shall make arrangements satisfactory to the
     Trustee for such deposit 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 (1) provided.
     Thereupon the Trustee shall fix a Special Record Date for the payment of
     such Defaulted Interest which shall be not more than 15 days and not less
     than 10 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 Securities of such series at his address as it appears in the
     Security Register, not less than 10 days prior to such Special Record Date.
     Notice of the proposed payment of such Defaulted Interest and the Special
     Record Date therefor having been so mailed, such Defaulted Interest shall
     be paid to the Persons in whose names the Securities of such series (or
     their respective Predecessor Securities) are registered at the close of
     business 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 on the
     Securities of any series in any other lawful manner not inconsistent with
     the requirements of any securities exchange on which the Securities of such
     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 (2), such manner of payment shall
     be deemed practicable by the Trustee.


                                     -31-
<PAGE>
 
          Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

SECTION 308.   Persons Deemed Owners.
               --------------------- 

          Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and any premium
and (subject to Section 307) any interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

SECTION 309.   Cancellation.
               ------------ 

          All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly canceled by it.  The Company may at any time deliver to
the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and may deliver to the Trustee (or to any other Person for delivery
to the Trustee) for cancellation any Securities previously authenticated
hereunder which the Company has not issued and sold, and all Securities so
delivered shall be promptly canceled by the Trustee.  No Securities shall be
authenticated in lieu of or in exchange for any Securities canceled as provided
in this Section, except as expressly permitted by this Indenture.  All canceled
Securities held by the Trustee shall be disposed of as directed by a Company
Order.

SECTION 310.   Computation of Interest.
               ----------------------- 

          Except as otherwise specified as contemplated by Section 301 for any
series of Securities, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

exchange of Securities herein expressly provided for), and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when

     been replaced or paid as provided in Section 306 and (ii) Securities for
     whose payment money has theretofore been deposited in trust or segregated

     and the Company, in the case of (i), (ii) or (iii) above, has deposited or
     caused to be deposited with the Trustee as trust funds in trust for the

     on such Securities not theretofore delivered to the Trustee for

determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money has been deposited with the Trustee.

SECTION 501.   Events of Default.
               ----------------- 

          "Event of Default", wherever used herein with respect to Securities of
any series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

          (1) default in the payment of any interest upon any Security of such
     series when it becomes due and payable, and continuance of such default for
     a period of 30 days; or

          (2) default in the payment of the principal of (or premium, if any,
     on) any Security of such series at its Maturity; or

          (3) default in the deposit of any sinking fund payment, when and as
     due by the terms of a Security of such series; or

          (4) default in the performance, or breach, of any covenant of the
     Company in this Indenture (other than a default in performance or breach of
     a covenant which is elsewhere in this Section specifically dealt with or
     which has expressly been included in this Indenture solely for the benefit
     of series of Securities other than such series), and continuance of such
     default or breach for a period of 60 days after there has been given, by
     registered or certified mail, to the Company by the Trustee or to the
     Company and the Trustee by the Holders of at least 10% in principal amount
     of the Outstanding Securities of such series a written notice specifying
     such default or breach and requiring it to be remedied and stating that
     such notice is a "Notice of Default" hereunder; or

          (5) default under any bond, debenture, note or other evidence of
     indebtedness for money borrowed by the Company (including a default with
     respect to Securities of any series other than such series) or any
     Subsidiary in an aggregate principal amount of at least $25,000,000 or
     under any mortgage, indenture or instrument under which there may be issued
     or by which there may be secured or evidenced any indebtedness for money
     borrowed by the Company (including this Indenture) or any Subsidiary in an
     aggregate principal amount of at least $25,000,000 whether such
     indebtedness now exists or shall hereafter be created, which default shall
     constitute a failure to pay any portion of the principal of such
     indebtedness when due and payable after the expiration of any applicable
     grace period with respect thereto or shall have resulted in such
     indebtedness becoming or being declared due and payable prior to the date
     on which it would otherwise have become due and payable, without such
     indebtedness having been discharged, or such acceleration having been
     rescinded or annulled, within a period of 30 days after there has been
     given, by registered or certified mail, to the Company by the Trustee or to
     the Company and the Trustee by the Holders of at least 10% in principal
     amount of the Outstanding Securities of such series a written notice
     specifying such default and requiring the Company to cause such
     indebtedness to be discharged or cause such acceleration to be rescinded or
     annulled and stating that such notice is a "Notice of Default" hereunder;
     provided, however, that, subject to the provisions of Sections 601 and 602,
     the Trustee shall not be deemed to have knowledge of such default unless
     either (A) a Responsible Officer of the Trustee shall have actual knowledge
     of such default or (B) the Trustee shall have received written notice
     thereof from the Company, from any

                                     -35-

     Holder, from the holder of any such indebtedness or from the trustee under
     any such mortgage, indenture or other instrument; or

          (6) the entry by a court having jurisdiction in the premises of (A) a
     decree or order for relief in respect of the Company in an involuntary case
     or proceeding under any applicable Federal or state bankruptcy, insolvency,
     reorganization or other similar law or (B) a decree or order adjudging the
     Company a bankrupt or insolvent, or approving as properly filed a petition
     seeking reorganization, arrangement, adjustment or composition of or in
     respect of the Company under any applicable Federal or state law, or
     appointing a custodian, receiver, liquidator, assignee, trustee,
     sequestrator or other similar official of the Company or of any substantial
     part of its property, or ordering the winding up or liquidation of its
     affairs, and the continuance of any such decree or order for relief or any
     such other decree or order unstayed and in effect for a period of 60
     consecutive days; or

     under any applicable Federal or state bankruptcy, insolvency,
     reorganization or other similar law or of any other case or proceeding to
     be adjudicated a bankrupt or insolvent, or the consent by it to the entry
     of a decree or order for relief in respect of the Company in an involuntary
     case or proceeding under any applicable Federal or state bankruptcy,
     insolvency, reorganization or other similar law or to the commencement of
     any bankruptcy or insolvency case or proceeding against it, or the filing
     by it of a petition or answer or consent seeking reorganization or relief
     under any applicable Federal or state law, or the consent by it to the
     filing of such petition or to the appointment of or taking possession by a
     custodian, receiver, liquidator, assignee, trustee, sequestrator or other
     similar official of the Company or of any substantial part of its property,
     or the making by it of an assignment for the benefit of creditors, or the
     admission by it in writing of its inability to pay its debts generally as
     they become due, or the taking of corporate action by the Company in
     furtherance of any such action; or

          (8) any other Event of Default provided with respect to Securities of
     such series.

          To the extent applicable, upon receipt by the Trustee of any Notice of
Default executed by a Holder pursuant to this Section 501, a record date shall
automatically and without any other action by any Person be set for the purpose
of determining the Holders of Outstanding Securities of such series entitled to
join in such Notice of Default, which record date shall be the

Holders of Outstanding Securities of such series on such record date (or their
duly appointed agents), and only such Persons, shall be entitled to join in such
Notice of Default, whether or not such Holders remain Holders after such record
date; provided, that unless such Notice of Default shall have become effective
by virtue of Holders of the requisite principal amount of Outstanding Securities
of such series on such record date (or their duly appointed agents) having
joined therein on or prior to the 90th day after such record date, such Notice
of Default shall automatically and without any action by any Person be canceled
and of no further force or effect.

SECTION 502.   Acceleration of Maturity;
               Rescission and Annulment.
               ------------------------ 

          If an Event of Default with respect to Securities of any series at the
time Outstanding occurs and is continuing, then in every such case the Trustee
or the Holders of not less than 25% in principal amount of the Outstanding
Securities of such series may declare the principal amount (or, if any of the
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount of such Securities as may be specified in the terms
thereof) of (and all accrued and unpaid interest on) all the Securities of such
series to be due and payable immediately, by a notice in writing to the Company
(and to the Trustee if given by Holders), and upon any such declaration such
principal amount (or specified amount) and interest shall become immediately due
and payable.  Upon payment of all such amounts (including interest accruing
through the date of payment), all obligations of the Company in respect of the
Securities of such series shall terminate.

          At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of such series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if

          (1) the Company has paid or deposited with the Trustee a sum
     sufficient to pay

               (A) all overdue interest on all Securities of such series,

               (B) the principal of (and premium, if any, on) any Securities of
          such series which have become due otherwise than by such declaration
          of acceleration and

                                     -37-
<PAGE>
 
          any interest thereon at the rate or rates prescribed therefor in such
          Securities,

               (C) to the extent that payment of such interest is lawful,
          interest upon overdue interest at the rate or rates prescribed
          therefor in such Securities, and

               (D) all sums paid or advanced by the Trustee hereunder and the
          reasonable compensation, expenses, disbursements and advances of the
          Trustee, its agents and counsel; and

          (2) all Events of Default with respect to Securities of such series,
     other than the nonpayment of the principal of and interest on the
     Securities of such series which have become due solely by such declaration
     of acceleration, have been cured or waived as provided in Section 513.

No such rescission and waiver shall affect any subsequent default or impair any
right consequent thereon.

          Upon receipt by the Trustee of any declaration of acceleration, or any
rescission and annulment of any such acceleration, pursuant to this Section 502,
a record date shall automatically and without any other action by any Person be
set for the purpose of determining the Holders of Outstanding Securities of such
series entitled to join in such declaration or rescission and annulment, as the
case may be, which record date shall be the close of business on the day the
Trustee receives such declaration or rescission and annulment, as the case may
be.  The Holders of Outstanding Securities of such series on such record date
(or their duly appointed agents), and only such Persons, shall be entitled to
join in such declaration or rescission and annulment, as the case may be,
whether or not such Holders remain Holders after such record date; provided,
that unless such declaration or rescission and annulment, as the case may be,
shall have become effective by virtue of Holders of the requisite principal
amount of Outstanding Securities of such series on such record date (or their
duly appointed agents) having joined therein on or prior to the 90th day after
such record date, such declaration or rescission and annulment, as the case may
be, shall automatically and without any action by any Person be canceled and of
no further force or effect.

SECTION 503.   Collection of Indebtedness and
               Suits for Enforcement by Trustee.
               -------------------------------- 

          The Company covenants that if

          (1) default is made in the payment of any interest on any Security
     when such interest becomes due and payable and such default continues for a
     period of 30 days, or

                                     -38-
<PAGE>
 
          (2) default is made in the payment of the principal of (or premium, 
     if any, on) any Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal and any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

          If an Event of Default with respect to the Securities of any series
occurs and is continuing, the Trustee may in its discretion proceed to protect
and enforce its rights and the rights of the Holders of Securities of such
series by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

SECTION 504.   Trustee May File Proofs of Claim.
               -------------------------------- 

          In case of any judicial proceeding relative to the Company or any
other obligor upon the Securities of any series or the property of the Company
or of such other obligor or their creditors, the Trustee shall be entitled and
empowered, by intervention in such proceeding or otherwise, to take any and all
actions authorized under the Trust Indenture Act in order to have the claims of
the Trustee and the Holders thereof allowed in any such proceeding.  In
particular, the Trustee shall be authorized to collect and receive any moneys or
other property payable or deliverable on any such claims and to distribute the
same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator
or other similar official in any such judicial proceeding is hereby authorized
by each such Holder to make such payments to the Trustee and, in the event that
the Trustee shall consent to the making of such payments directly to such
Holders, to pay to the Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 607.

          No provision of this Indenture shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the
Securities

                                     -39-
<PAGE>
 
of a series or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder thereof in any such proceeding.

SECTION 505.   Trustee May Enforce Claims
               Without Possession of Securities.
               -------------------------------- 

          All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name,
as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

SECTION 506.   Application of Money Collected.
               ------------------------------ 

          Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal or any premium
or interest, upon presentation of the Securities for which such money was
collected and the notation thereon of the payment if only partially paid and
upon surrender thereof if fully paid:

          FIRST:  To the payment of all amounts due the Trustee under Section
     607; and

          SECOND:  To the payment of the amounts then due and unpaid for
     principal of and any premium and interest on the Securities in respect of
     which or for the benefit of which such money has been collected, ratably,
     without preference or priority of any kind, according to the amounts due
     and payable on such Securities for principal and any premium and interest,
     respectively.

SECTION 507.   Limitation on Suits.
               ------------------- 

          No Holder of any Security of any series shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Indenture,
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless

          (1) such Holder has previously given written notice to the Trustee of
     a continuing Event of Default with respect to the Securities of such
     series;

                                     -40-
<PAGE>
 
          (2) the Holders of not less than 25% in principal amount of the
     Outstanding Securities of such series shall have made written request to
     the Trustee to institute proceedings in respect of such Event of Default in
     its own name as Trustee hereunder;

          (3) such Holder or Holders have offered to the Trustee reasonable
     indemnity against the costs, expenses and liabilities to be incurred in
     compliance with such request;

          (4) the Trustee for 60 days after its receipt of such notice, request
     and offer of indemnity has failed to institute any such proceeding; and

          (5) no direction inconsistent with such written request has been given
     to the Trustee during such 60-day period by the Holders of a majority in
     principal amount of the Outstanding Securities of such series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatsoever by virtue of, or by availing of, any
provision of this Indenture (including without limitation the provisions of
Section 512) to affect, disturb or prejudice the rights of any other of such
Holders or to obtain or to seek to obtain priority or preference over any other
of such Holders or to enforce any right under this Indenture, except in the
manner herein provided and for the equal and ratable benefit of all of such
Holders.

SECTION 508.   Unconditional Right of Holders
               to Receive Principal, Premium and Interest.
               ------------------------------------------ 

          Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of and any premium and (subject to Section 307)
interest on such Security on the Stated Maturity or Maturities expressed in such
Security (or, in the case of redemption on the Redemption Date) and to institute
suit for the enforcement of any such payment, and such rights shall not be
impaired without the consent of such Holder.

SECTION 509.   Restoration of Rights and Remedies.
               ---------------------------------- 

          If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies

                                     -41-
<PAGE>
 
of the Trustee and the Holders shall continue as though no such proceeding had
been instituted.

SECTION 510.   Rights and Remedies Cumulative.
               ------------------------------ 

          Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in Section 306, no
right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise.  The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

SECTION 511.   Delay or Omission Not Waiver.
               ---------------------------- 

          No delay or omission of the Trustee or of any Holder of any Security
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
any acquiescence therein.  Every right and remedy given by this Article or by
law to the Trustee or to any Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by such Holders, as the case
may be.

SECTION 512.   Control by Holders.
               ------------------ 

          The Holders of a majority in principal amount of the Outstanding
Securities of any series 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 with respect to the
Securities of such series; provided, that

          (1) such direction shall not be in conflict with any rule of law or
     with this Indenture;

          (2) the Trustee may take any other action deemed proper by the Trustee
     which is not inconsistent with such direction; and

          (3) subject to the provisions of Section 601, the Trustee shall have
     the right to decline to follow any such direction if the Trustee in good
     faith shall, by Responsible Officer or Officers of the Trustee, determine
     that the action so directed would involve the Trustee in personal liability
     for which it has not been adequately indemnified or would be unduly
     prejudicial to Holders not joining in such direction.


                                     -42-
<PAGE>
 
          Upon receipt by the Trustee of any such direction, pursuant to this
Section 512, a record date shall automatically and without any other action by
any Person be set for the purpose of determining the Holders of Outstanding
Securities of any series entitled to join in such direction, which record date
shall be the close of business on the day the Trustee receives such direction.
The Holders of Outstanding Securities of such series on such record date (or
their duly appointed agents), and only such Persons, shall be entitled to join
in such direction, whether or not such Holders remain Holders after such record
date; provided, that unless such direction shall have become effective by virtue
of Holders of the requisite principal amount of Outstanding Securities of such
series on such record date (or their duly appointed agents) having joined
therein on or prior to the 90th day after such record date, such direction shall
automatically and without any action by any Person be canceled and of no further
force or effect.

SECTION 513.   Waiver of Defaults.
               ------------------ 

          The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series waive any default hereunder with respect to such
series and its consequences, except a default

          (1) in the payment of the principal of or any premium or interest on
     any Security of such series, or

          (2) in respect of a covenant or provision hereof which under Article
     Nine cannot be modified or amended without the consent of the Holder of
     each Outstanding Security of such series affected.

          Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

SECTION 514.   Undertaking for Costs.
               --------------------- 

          In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess costs against
any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided, that neither this Section nor the Trust Indenture Act
shall be deemed to authorize any court to require such an undertaking or to make
such an assessment in any suit instituted by the Company, the Trustee or the
Holders of 10%

                                     -43-
<PAGE>
 
or more in principal amount of the Outstanding Securities of any series.

SECTION 515.   Waiver of Stay or Extension Laws.
               -------------------------------- 

          The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants so that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.


                                  ARTICLE SIX

Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it.  Whether or not therein
expressly so provided, every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

SECTION 602.   Notice of Defaults.
               ------------------ 

          If a default occurs hereunder with respect to Securities of any
series, the Trustee shall give the Holders of Securities of such series notice
of such default as and to the extent provided by the Trust Indenture Act;
provided, however, that in the case of any default of the character specified in
Section 501(4) with respect to Securities of such series, no such notice to
Holders shall be given until at least 30 days after the occurrence thereof.  For
the purpose of this Section, the term "default" means any event which is, or
after notice or lapse of time or both would become, an Event of Default with
respect to Securities of such series.

     Indenture with respect to the Securities of such series;

     Office and such notice refers to the Securities of any series, the Company
     or this Indenture; and

          (l) in the event that the Trustee is also acting as Paying Agent,
     Authenticating Agent or Security Registrar hereunder, the rights and
     protections afforded to the Trustee pursuant to this Article Six shall also
     be afforded to it as such Paying Agent, Authenticating Agent or Security
     Registrar.

SECTION 604.   Not Responsible for Recitals
               or Issuance of Securities.
               ------------------------- 

          The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and the Trustee or any Authenticating Agent assumes no
responsibility for their correctness.  The Trustee makes no representations as

               ------------------- 

          The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
608 and 613, may otherwise deal with the Company with the same rights it would

                                     -46-
<PAGE>
 
have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

SECTION 606.   Money Held in Trust.
               ------------------- 

          Money held by the Trustee or any Paying Agent (except the Company) in

          (1) to pay to the Trustee from time to time reasonable compensation
     for all services rendered by it hereunder as may be mutually agreed upon in
     writing by the Company and the Trustee (which compensation shall not be
     limited by any provision of law in regard to the compensation of a trustee
     of an express trust);

          (2) except as otherwise expressly provided herein, to reimburse the
     Trustee upon its request for all reasonable expenses, disbursements and

particular Securities.

          If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture.

SECTION 609.   Corporate Trustee Required; Eligibility.
               ---------------------------------------

the bank holding company of which it is a wholly owned subsidiary, a combined

such Person publishes reports of condition at least annually, pursuant to law or

then for the purposes of this Section the combined capital and surplus of such
Person shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, it

SECTION 610.   Resignation and Removal; Appointment of Successor.
               ------------------------------------------------- 

          (a) No resignation or removal of the Trustee and no appointment of a
successor or additional Trustee pursuant to this Article shall become effective
until the acceptance of appointment by the successor or additional Trustee in
accordance with the applicable requirements of Section 611.

          (b) The Trustee may resign at any time with respect to the Securities
of one or more series by giving written notice thereof to the Company.  If the
instrument of acceptance by a successor or additional Trustee required by
Section 611 shall not have been delivered to the resigning Trustee within 30
days after the giving of such notice of resignation, the resigning Trustee

                                     -48-
<PAGE>
 
may petition any court of competent jurisdiction for the appointment of a
successor or additional Trustee.

          (c) The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series delivered to the Trustee and to the
Company.

          (d)  If at any time:

          (1) the Trustee shall fail to comply with Section 608 after written
     request therefor by the Company or by any Holder who has been a bona fide
     Holder of a Security for at least six months, or

          (2) the Trustee shall cease to be eligible under Section 609 and shall
     fail to resign after written request therefor by the Company or by any such
     Holder, or

          (3) the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent or a receiver of the Trustee or of its property
     shall be appointed or any public officer shall take charge or control of
     the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee with respect to all Securities, or (ii) subject to Section 514, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee and the appointment of
a successor Trustee or Trustees.

          (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Securities of such series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of
such series and that at any time there shall be only one Trustee with respect to
the Securities of any particular series) and such successor Trustee or Trustees
shall comply with the applicable requirements of Section 611.  If, within one
year after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee with respect to the Securities of any series shall
be appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in

                                     -49-
<PAGE>

Trustee with respect to the Securities of such series and to that extent
supersede the successor Trustee appointed by the Company.  If no successor
Trustee with respect to the Securities of any series shall have been so
appointed by the Company or the Holders and accepted appointment in the manner
required by Section 611, any Holder who has been a bona fide Holder of a
Security of such series for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the appointment of a successor Trustee with respect to the Securities of such
series.

          (f) The Company shall give notice of each resignation and each removal
of the Trustee with respect to the Securities of any series and each appointment

Holders of Securities of such series in the manner provided in Section 106.
Each notice shall include the name of the successor Trustee with respect to the

SECTION 611.   Acceptance of Appointment by Successor.
               -------------------------------------- 

          (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on the request
of the Company or the successor Trustee, such retiring Trustee shall, upon
payment of its charges, execute and deliver an instrument transferring to such
successor Trustee all the rights, powers and trusts of the retiring Trustee and
shall duly assign, transfer and deliver to such successor Trustee all property

the retiring Trustee.

          (b) In case of the appointment hereunder of a Trustee with respect to
the Securities of one or more (but not all) series, the Company, the retiring
Trustee and each successor Trustee with respect to the Securities of one or more
series shall execute and deliver an indenture supplemental hereto wherein each
successor Trustee shall accept such appointment and which (1) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Trustee all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of such series to which the
appointment of such successor Trustee

                                     -50-
<PAGE>
 
relates, (2) if the retiring Trustee is not retiring with respect to all
Securities, shall contain such provisions as shall be deemed necessary or
desirable to confirm that all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of such series as to which the
retiring Trustee is not retiring shall continue to be vested in the retiring
Trustee, and (3) shall add to or change any of the provisions of this Indenture
as shall be necessary to provide for or facilitate the administration of the
trusts hereunder by more than one Trustee, it being understood that nothing
herein or in such supplemental indenture shall constitute such Trustees co-
trustees of the same trust and that each such Trustee shall be trustee of a
trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee; and upon the execution and delivery of
such supplemental indenture the resignation or removal of the retiring Trustee
shall become effective to the extent provided therein and each such successor
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Trustee with respect
to the Securities of such series to which the appointment of such successor
Trustee relates; but, on request of the Company or any successor Trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of such series to which the appointment of such
successor Trustee relates.

          (c) Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in paragraph (a) or (b) of this Section, as the case may be.

          (d) No successor Trustee shall accept its appointment unless at the
time of such acceptance such successor Trustee shall be qualified and eligible
under this Article.

SECTION 612.   Merger, Conversion, Consolidation
               or Succession to Business.
               ------------------------- 

          Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder; provided, that
such corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto.  In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in

                                     -51-
<PAGE>
 
office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Securities
so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities.

SECTION 613.   Preferential Collection of Claims Against Company.
               ------------------------------------------------- 

          If and when the Trustee shall be or become a creditor of the Company
(or any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

SECTION 614.   Authenticating Agents.
               --------------------- 

          The Trustee may appoint an Authenticating Agent or Agents with respect
to one or more series of Securities which shall be authorized to act on behalf
of the Trustee to authenticate Securities of such series issued upon original
issue and upon exchange, registration of transfer or partial redemption thereof
or pursuant to Section 306, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Any such Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any state thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of at least $10,000,000 and,
together with the bank holding company of which it is a wholly owned subsidiary,
a combined capital and surplus of at least $100,000,000, and subject to
supervision or examination by Federal, state or District of Columbia authority.
If either such Person publishes reports of its condition at least annually,
pursuant to law or the requirements of said supervising or examining authority,
then, for the purposes of this Section, the combined capital and surplus of such
Person shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible to act as such in accordance
with the provisions of this Section, such Authenticating Agent shall resign
immediately in the manner and with the effect specified in this Section.
 

          Any corporation into which any Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or

                                     -52-
<PAGE>
 
consolidation to which any Authenticating Agent shall be a party, or any
corporation succeeding to the corporate agency or corporate trust business of
any Authenticating Agent, shall continue to be Authenticating Agent hereunder;
provided, that such successor corporation shall be otherwise eligible under this
Section, without the execution or filing of any paper or any further act on the
part of the Trustee or such Authenticating Agent.

          An Authenticating Agent may resign at any time by giving written
notice of resignation to the Trustee and to the Company.  The Trustee may at any
time terminate the agency of any Authenticating Agent by giving written notice
of termination to such Authenticating Agent and to the Company.  Upon receiving
such a notice of resignation or upon such a termination, or in case at any time
any Authenticating Agent shall cease to be eligible to act as such in accordance
with the provisions of this Section, the Trustee may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall mail
notice of such appointment by first-class mail, postage prepaid, to all Holders
of Securities of the applicable series as their names and addresses appear in
the Security Register.  Any successor Authenticating Agent upon acceptance of
its appointment under this Section shall become vested with all the rights,
powers, duties and obligations of its predecessor hereunder, with like effect as
if initially named as an Authenticating Agent.  No successor Authenticating
Agent shall be appointed unless eligible to act as such in accordance with the
provisions of this Section.

          Any Authenticating Agent by the acceptance of its appointment shall be
deemed to have represented to the Trustee that it is eligible for appointment as
Authenticating Agent under this Section and to have agreed with the Trustee
that: it will perform and carry out the duties of an Authenticating Agent as
herein set forth, including among other things the duties to authenticate
Securities when presented to it in connection with exchanges, registrations of
transfer thereof or pursuant to Section 306; it will keep and maintain, and
furnish to the Trustee from time to time as requested by the Trustee,
appropriate records of all transactions carried out by it as Authenticating
Agent and will furnish the Trustee such other information and reports as the
Trustee may reasonably require; and it will notify the Trustee promptly if it
shall cease to be eligible to act as Authenticating Agent in accordance with the
provisions of this Section.  Any Authenticating Agent by the acceptance of its
appointment shall be deemed to have agreed with the Trustee to indemnify the
Trustee against any loss, liability or expense incurred by the Trustee and to
defend any claim asserted against the Trustee by reason of any acts or failures
to act of such Authenticating Agent, but such Authenticating Agent shall have no
liability for any action taken by it in accordance with the specific written
direction of the Trustee.

                                     -53-
<PAGE>
 
          The Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 607.

          If an appointment with respect to one or more series is made pursuant
to this Section, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certification of authentication, an alternative
certificate of authentication in the following form:

          This is one of the Securities of the series designated herein referred
to in the within-mentioned Indenture.

     amount thereof or the rate of interest thereon or any premium payable upon
     the redemption or repurchase thereof, or reduce the amount of the principal
     of an Original Issue Discount Security that would be due and payable upon a
     declaration of acceleration of the Maturity thereof pursuant to Section
     502, or change any Place of Payment where, or the coin or currency in
     which, any Security or any premium or interest thereon is payable, or
     impair the right to institute suit for the enforcement of any such payment
     on or after the Stated Maturity thereof (or, in the case of redemption, on
     or after the Redemption Date); or

          (2) reduce the percentage in principal amount of the Outstanding
     Securities of any series, the consent of whose Holders is required for any
     such supplemental indenture, or the consent of whose Holders is required
     for any waiver of compliance with certain provisions of this Indenture or
     certain defaults hereunder and their consequences provided for in this
     Indenture; or

          (3) modify any of the provisions of this Section or Section 513 or
     Section 1010, except to increase any such percentage or to provide that
     certain other provisions of this Indenture cannot be modified or waived
     without the consent of the Holder of each Outstanding Security affected
     thereby; provided, however, that this clause shall not be deemed to require
     the consent of any Holder with respect to changes in the references to "the
     Trustee" and concomitant changes in this Section and Section 1010, or the
     deletion of this proviso, in accordance with the requirements of Sections
     611(b) and 901(8).

A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the
rights of the Holders of Securities of such series with respect to such covenant
or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

          It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

SECTION 903.   Execution of Supplemental Indentures.
               ------------------------------------ 

          In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 601) shall be fully protected in relying upon, an
Officer's Certificate and an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture.  The
Trustee may, but shall not be obligated to, enter into any such supplemental
indenture which adversely affects the Trustee's own rights, duties, immunities
or liabilities under this Indenture or otherwise.

SECTION 904.   Effect of Supplemental Indentures.
               --------------------------------- 

          Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

SECTION 905.   Conformity With Trust Indenture Act.
               ----------------------------------- 

          Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act.

SECTION 906.   Reference in Securities
               to Supplemental Indentures.
               -------------------------- 

          Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture.  If the Company shall
so determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture may
be prepared and executed by the Company and authenticated and delivered by the
Trustee in exchange for Outstanding Securities of such series.

SECTION 907.   Notice of Supplemental Indenture.
               -------------------------------- 

          Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to Section 902, the Company shall transmit to
the Holders of Outstanding Securities of any series affected thereby a notice
setting forth the substance of such supplemental indenture.

SECTION 1001.  Payment of Principal, Premium and Interest.
               ------------------------------------------- 

          The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any premium
and interest on the Securities of such series in accordance with the terms of
the Securities and this Indenture.

SECTION 1002.  Maintenance of Office or Agency.
               ------------------------------- 

          The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of such series may be presented
or surrendered for payment, where Securities of such series may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Company in respect of the Securities of such series and this Indenture
may be served.  The Company will give prompt written notice to the Trustee of
the location, and of any change in the location, of such office or agency.  If
at any time the Company shall fail to maintain any such required office or
agency or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee, and the Company hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

          The Company may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in each Place of Payment for any series of Securities for such
purposes.  The Company will give prompt written notice to the Trustee of any
such designation or rescission and of any change in the location of any such
other office or agency.

Section 1003.  Money for Payments to be Held in Trust.
               -------------------------------------- 

          If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of or any premium or interest on any of the Securities of such series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal or any premium or interest so becoming due
until such sums shall be paid to such Persons or

                                     -61-
<PAGE>
 
otherwise disposed of as herein provided, and will promptly notify the Trustee
of its action or failure so to act.

          Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, prior to each due date of the principal of or any
premium or interest on any Securities of such series, deposit with any such
Paying Agent a sum sufficient to pay the principal or premium or interest so
becoming due, such sum to be held as provided by the Trust Indenture Act, and
(unless such Paying Agent is the Trustee) the Company will promptly notify the
Trustee of its action or failure so to act.

          The Company will cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will:

          (1) comply with the provisions of the Trust Indenture Act applicable
     to it as a Paying Agent and hold all sums held by it for the payment of
     principal of or interest on any Securities in trust for the benefit of the
     Persons entitled thereto until such sums shall be paid to such Persons or
     otherwise disposed of as herein provided; and

          (2) at any time during the continuance of any default by the Company
     (or any other obligor upon the Securities of such series) in the making of
     any payment in respect of the Securities of such series, upon the written
     request of the Trustee, forthwith pay to the Trustee all sums so held in
     trust by such Paying Agent for payment in respect of the Securities of such
     series.

          The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

          Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of or any premium or
interest on any Security of any series and remaining unclaimed for two years
after such principal, premium or interest has become due and payable shall be
paid to the Company on Company Request, or (if then held by the Company) shall
be discharged from such trust; and the Holder of such Security shall thereafter,
as an unsecured general

                                     -62-

creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee thereof, shall thereupon cease; provided, however,
that the Trustee or such Paying Agent, before being required to make any such
repayment, may at the expense of the Company cause to be published once, in a
newspaper of general circulation in The City of New York, Borough of Manhattan,
and printed in the English language and customarily published on each Business
Day, whether or not published on Saturdays, Sundays or holidays, notice that
such money remains unclaimed and that, after a date specified therein, which
shall not be less than 30 days from the date of such publication, any unclaimed
balance of such money then remaining will be repaid to the Company.

               ------------------- 

          (a) Except as otherwise provided in clauses (1) through (9) below or
in subsection (b) of this Section, the Company shall not, and shall not permit
any Restricted Subsidiary to, issue, assume or guarantee any Debt secured by a
Lien upon any Principal Property of the Company or of any Restricted Subsidiary
or upon any shares of stock or Debt issued by any Restricted Subsidiary (whether
such Principal Property, shares of stock or Debt are now owned or hereafter
acquired) without in any such case effectively providing concurrently with the
issuance, assumption or guaranty of any such Debt that the Securities (together
with, if the Company shall so determine, any other indebtedness of or guaranty
by the Company or such Restricted Subsidiary then existing or thereafter created
which is not subordinated to the Securities) shall be secured equally and
ratably with (or, at the option of the Company, prior to) such Debt, so long as
such Debt shall be so secured; provided, however, that nothing in this Section
1004 shall prevent, restrict or apply to (and there shall be excluded from
secured Debt in any computation under this Section 1004) Debt secured by:

          (1) Liens on property of, or shares of stock or Debt issued by, any
     Subsidiary existing at the time it becomes a Restricted Subsidiary;
     provided, that such Lien shall not have been incurred in connection with
     the transfer by the Company or a Restricted Subsidiary of a Principal
     Property to such Subsidiary unless the Company, within 180 days of the
     effective date of such transfer, applies or causes a Restricted Subsidiary
     to apply an amount equal to the fair value, as determined by the Board of
     Directors, of such Principal Property at the time of such transfer, to the
     retirement of Securities or other Debt of the Company (other than Debt
     subordinated to the Securities), or Debt of any Restricted Subsidiary
     (other than Debt owed to the Company or any Restricted Subsidiary), having
     a stated maturity (i) more than 12 months from the date of such application
     or

                                     -63-
<PAGE>
 
     (ii) which is extendable at the option of the obligor thereon to a date
     more than 12 months from the date of such application;

          (2) Liens on any property, shares of stock or Debt existing at the
     time of acquisition thereof (including acquisition through merger or
     consolidation) or securing the payment of all or any part of the purchase
     price or construction cost thereof or securing any Debt incurred prior to,
     at the time of, or within 180 days after, the acquisition of such property,
     shares of stock or Debt or the completion of any such construction,
     whichever is later, for the purpose of financing all or any part of the
     purchase price or construction cost thereof;

          (3) Liens on any property to secure all or any part of the cost of
     development, construction, alteration, repair or improvement of all or any
     part of such property, or to secure Debt incurred prior to, at the time of,
     or within 180 days after, the completion of such development, construction,
     alteration, repair or improvement, whichever is later, for the purpose of
     financing all or any part of such cost;

          (4) Liens which secure Debt owing by a Restricted Subsidiary to the
     Company or to another Restricted Subsidiary or by the Company to a
     Restricted Subsidiary so long as the Debt is held by the Company or a
     Restricted Subsidiary;

          (5) Liens securing indebtedness of a corporation or other Person which
     becomes a successor of the Company in accordance with the provisions of
     Article Eight other than  Debt incurred by such corporation or other Person
     in connection with a consolidation, merger or sale of assets in accordance
     with such Article;

          (6) Liens on property of the Company or a Restricted Subsidiary in
     favor of the United States of America or any state thereof, or any
     department, agency or instrumentality or political subdivision of the
     United States of America or any state thereof, or in favor of any other
     country or any political subdivision thereof, to secure partial, progress,
     advance or other payments pursuant to any contract or statute or to secure
     any indebtedness incurred or guaranteed for the purpose of financing all or
     any part of the purchase price or the cost of construction, alteration,
     repair or improvement of the property subject to such Liens (including but
     not limited to Liens incurred in connection with pollution control,
     industrial revenue or similar financing), or in favor of any trustee or
     mortgagee for the benefit of

                                     -64-
<PAGE>
 
     holders of indebtedness of any such entity incurred for any such purpose;

          (7) Liens securing Debt which is payable, both with respect to
     principal and interest, solely out of the proceeds of oil, gas, coal or
     other minerals to be produced from the property subject thereto and to be
     sold or delivered by the Company or a Subsidiary, including any interest of
     the character commonly referred to as a "production payment";

          (8) Liens created or assumed by a Subsidiary on oil, gas, coal or
     other mineral property, owned or leased by a Subsidiary, to secure Debt of
     such Subsidiary for the purpose of developing such property, including any
     interest of the character commonly referred to as a "production payment";
     provided, however, that neither the Company nor any other Subsidiary shall
     assume or guarantee such Debt or otherwise be liable in respect thereof;
     and

          (9) any extension, renewal or replacement (or successive extensions,
     renewals or replacements), in whole or in part, of any Lien referred to in
     the foregoing clauses (1) to (8), inclusive, or of any Debt secured
     thereby; provided, that such extension, renewal or replacement Lien shall
     be limited to all or any part of the same property that secured the Lien
     extended, renewed or replaced (plus any improvements and construction on
     such property) and shall secure no larger amount of Debt than that which
     had been so secured at the time of such extension, renewal or replacement
     and, in the case of clause (4), that the Debt being secured thereby is
     being secured for the same type of Person as the Debt being replaced.

          (b) Notwithstanding the foregoing provisions of this Section 1004, the
Company and any one or more Restricted Subsidiaries may issue, assume or
guarantee Debt secured by a Lien which would otherwise be subject to the
foregoing restrictions if at the time it does so (the "Incurrence Time") the
aggregate amount of such Debt plus all other Debt of the Company and its

foregoing restrictions after giving effect to the retirement of any Debt which
is currently being retired (not including Debt permitted to be secured under
clauses (1) through (9) above), plus the aggregate Attributable Debt (determined
as of the Incurrence Time) of Sale and Leaseback Transactions (other than Sale
and Leaseback Transactions permitted by subsections (a) and (b) of Section 1005)

the aggregate amount of proceeds of such Sale and Leaseback Transactions which
shall have been applied in accordance with

                                     -65-

Tangible Assets.

SECTION 1005.  Limitation on Sale and Leaseback Transactions.
               --------------------------------------------- 

          The Company shall not itself, and shall not permit any Restricted
Subsidiary to, enter into any arrangements after June __, 1996 with any bank,
insurance company or other lender or investor (other than the Company or another
Restricted Subsidiary) providing for the leasing as lessee by the Company or by
any such Restricted Subsidiary of any Principal Property (except a lease for a
temporary period not to exceed three years by the end of which it is intended
the use of such Principal Property by the lessee will be discontinued and a
lease which secures or relates to industrial revenue or pollution control bonds
or similar financing), which was or is owned by the Company or a Restricted
Subsidiary and which has been or is to be sold or transferred by the Company or
a Restricted Subsidiary, more than 180 days after the completion of construction
and commencement of full operation thereof by the Company or such Restricted
Subsidiary, to such lender or investor or to any Person to whom funds have been
or are to be advanced by such lender or investor on the security of such
Principal Property (herein called a "Sale and Leaseback Transaction") unless:

          (a) the Company or such Restricted Subsidiary would (at the time of
     entering into such arrangement) be entitled pursuant to clauses (1) through
     (9) of subsection (a) of Section 1004, without equally and ratably securing
     the Securities, to issue, assume or guarantee Debt secured by a Lien on
     such Principal Property in the amount of the Attributable Debt arising from
     such Sale and Leaseback Transaction; or

          (b) the Attributable Debt of the Company and its Restricted
     Subsidiaries in respect of such Sale and Leaseback Transaction and all
     other Sale and Leaseback Transactions entered into after June __, 1996
     (other than such Sale and Leaseback Transactions as are permitted by
     subsection (a) or (c) of this Section 1005), plus the aggregate principal
     amount of Debt secured by Liens on Principal Properties then outstanding
     (not including any such Debt secured by Liens described in clauses (1)
     through (9) of subsection (a) of Section 1004) which do not equally and
     ratably secure the Securities, would not exceed 10% of Consolidated Net
     Tangible Assets; or

          (c) the Company, within 180 days after the sale or transfer, applies
     or causes a Restricted Subsidiary to apply an amount equal to the greater
     of the net proceeds of such sale or transfer or the fair value, as
     determined by the Board of Directors, of the Principal Property so sold and

                                     -66-
<PAGE>
 
     leased back at the time of entering into such Sale and Leaseback
     Transaction to the retirement of Securities or other Debt of the Company
     (other than Debt subordinated to the Securities), or Debt of any Restricted
     Subsidiary (other than Debt owed to the Company or any Restricted
     Subsidiary), having a stated maturity (i) more than 12 months from the date
     of such application or (ii) which is extendable at the option of the
     obligor thereon to a date more than 12 months from the date of such
     application; provided, that the amount to be so applied shall be reduced by
     (x) the principal amount of Securities delivered to the Trustee for
     retirement and cancellation within 180 days after such sale or transfer,
     and (y) the principal amount of any such Debt of the Company or a
     Restricted Subsidiary other than Securities voluntarily retired by the
     Company or a Restricted Subsidiary within 180 days after such sale or
     transfer.  Notwithstanding the foregoing, no retirement referred to in this
     subdivision (c) may be effected by payment at Maturity.

Notwithstanding the foregoing, where the Company or any Restricted Subsidiary is
the lessee in any Sale and Leaseback Transaction, Attributable Debt shall not
include any Debt resulting from the guarantee by the Company or any other
Restricted Subsidiary of the lessee's obligation thereunder.

SECTION 1006.  Existence.
               --------- 

          Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its existence,
rights (charter and statutory) and franchises; provided, however, that the
Company shall not be required to preserve any such right or franchise if the
Board of Directors shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company and that the loss
thereof is not disadvantageous in any material respect to the Holders.

SECTION 1007. Maintenance of Properties.
              ------------------------- 

          The Company will cause all properties used or useful in the conduct of
its business or the business of any Subsidiary to be maintained and kept in good
condition, repair and working order and supplied with all necessary equipment
and will cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in the judgment of the Company may
be necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times; provided, however, that
nothing in this Section shall prevent the Company from discontinuing the
operation or maintenance of any of such properties if such discontinuance is, in
the judgment of the Company, desirable in the conduct of its

                                     -67-
<PAGE>
 
business or the business of any Subsidiary and not disadvantageous in any
material respect to the Holders.

SECTION 1008.  Payment of Taxes and Other Claims.
               --------------------------------- 

          The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all taxes, assessments and
governmental charges levied or imposed upon the Company or any Subsidiary or
upon the income, profits or property of the Company or any Subsidiary, and (2)
all lawful claims for labor, materials and supplies which, if unpaid, might by
law become a lien upon the property of the Company or any Subsidiary; provided,
however, that the Company shall not be required to pay or discharge or cause to
be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings.

SECTION 1009.  Statement as to Compliance.
               -------------------------- 

          The Company will deliver to the Trustee, within 120 days after the end
of each fiscal year of the Company ending after the date hereof, an Officer's
Certificate stating whether or not to the best knowledge of the signers thereof
the Company is in default in the performance and observance of any of the
provisions and conditions of this Indenture (without regard to any period of
grace or requirement of notice provided hereunder) and, if the Company shall be
in default, specifying all such defaults and the nature and status thereof of
which they have knowledge.

SECTION 1010.  Waiver of Certain Covenants.
               --------------------------- 

          The Company may omit in any particular instance to comply with any
provision or condition set forth in Sections 1004 and 1005, inclusive, with
respect to the Securities of any series if before the time for such compliance
the Holders of at least 66 2/3% in principal amount of the Outstanding
Securities of such series shall, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such provision or
condition, but no such waiver shall extend to or affect such provision or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee
in respect of any such provision or condition shall remain in full force and
effect.

SECTION 1101.  Applicability of Article.
               ------------------------ 

          Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for any series of Securities)
in accordance with this Article.

SECTION 1102.  Election to Redeem; Notice to Trustee.
               ------------------------------------- 

          The election of the Company to redeem any Securities shall be
evidenced by a Board Resolution.  In case of any redemption at the election of
the Company of less than all the Securities of any series, the Company shall, at
least 60 days prior to the Redemption Date fixed by the Company (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date, of the principal amount of Securities of such series to be
redeemed and, if applicable, of the tenor of the Securities to be redeemed.  In
the case of any redemption of Securities prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, the Company shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction.

SECTION 1103.  Selection by Trustee of Securities to be Redeemed.
               ------------------------------------------------- 

          If less than all the Securities of any series are to be redeemed
(unless all of the Securities of such series and of a specified tenor are to be
redeemed), the particular Securities to be redeemed shall be selected not more
than 60 days prior to the Redemption Date by the Trustee from the Outstanding
Securities of such series not previously called for redemption, by such method
as the Trustee shall deem fair and appropriate and which may provide for the
selection for redemption of portions (equal to the minimum authorized
denomination for Securities of that series or any integral multiple thereof) of
the principal amount of Securities of such series of a denomination larger than
the minimum authorized denomination for Securities of such series.  If less than
all of the Securities of such series and of a specified tenor are to be
redeemed, the particular Securities to be redeemed shall be selected not more
than 60 days prior to the Redemption Date by the Trustee, from the Outstanding
Securities of such series and specified tenor not previously called for
redemption in accordance with the preceding sentence.

          The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption and, in the

                                     -69-

case of any Securities selected for partial redemption, the principal amount
thereof to be redeemed.

          For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the
portion of the principal amount of such Securities which has been or is to be
redeemed.

SECTION 1104.  Notice of Redemption.
               -------------------- 

          Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed, at his address appearing in
the Security Register.

          All notices of redemption shall state:

          (1)  the Redemption Date,

          (2)  the Redemption Price,

          (3) if less than all the Outstanding Securities of any series are to
          be redeemed, the identification (and, in the case of partial
          redemption of any Securities, the principal amounts) of the particular
          Securities to be redeemed,

          (4) that on the Redemption Date the Redemption Price will become due
          and payable upon each such Security to be redeemed and, if applicable,
          that interest thereon will cease to accrue on and after said date,

          (5) the place or places where such Securities are to be surrendered
          for payment of the Redemption Price, and

          (6) that the redemption is for a sinking fund, if such is the case.

          Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

SECTION 1105.  Deposit of Redemption Price.
               --------------------------- 

          Prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall

                                     -70-
<PAGE>
 
be an Interest Payment Date) accrued interest on, all the Securities which are
to be redeemed on that date.

SECTION 1106.  Securities Payable on Redemption Date.
               ------------------------------------- 

          Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest.  Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that, unless otherwise specified as
contemplated by Section 301, installments of interest whose Stated Maturity is
on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

          If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal and any premium shall, until
paid, bear interest from the Redemption Date at the rate prescribed therefor in
the Security.

SECTION 1107.  Securities Redeemed in Part.
               --------------------------- 

          Any Security which is to be redeemed only in part shall be surrendered
at a Place of Payment therefor (with, if the Company or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to
the Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver to the Holder of such Security without service
charge, a new Security or Securities of the same series and of like tenor, of
any authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.

SECTION 1201.  Applicability of Article.
               ------------------------ 

          The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of a series except as otherwise specified as
contemplated by Section 301 for Securities of such series.

                                     -71-
<PAGE>
 
          The minimum amount of any sinking fund payment provided for by the
terms of the Securities of any series is herein referred to as a "mandatory
sinking fund payment", and any payment in excess of such minimum amount provided
for by the terms of Securities of any series is herein referred to as an
"optional sinking fund payment".  If provided for by the terms of the Securities
of any series, the cash amount of any sinking fund payment may be subject to
reduction as provided in Section 1202.  Each sinking fund payment shall be
applied to the redemption of Securities of a series as provided for by the terms
of Securities of such series.

SECTION 1202.  Satisfaction of Sinking Fund 
               Payments with Securities.
               ------------------------- 

          The Company (1) may deliver Outstanding Securities of a series (other
than any previously called for redemption) and (2) may apply as a credit
Securities of a series which have been redeemed either at the election of the
Company pursuant to the terms of such Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of such series required to be made
pursuant to the terms of such Securities as provided for by the terms of such
Series; provided, that such Securities have not been previously so credited.
Such Securities shall be received and credited for such purpose by the Trustee
at the Redemption Price specified in such Securities for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly.

SECTION 1203.  Redemption of Securities for Sinking Fund.
               ----------------------------------------- 

          Not less than 60 days prior to each sinking fund payment date for a
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
such series pursuant to the terms of such series, the portion thereof, if any,
which is to be satisfied by payment of cash and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of such series
pursuant to Section 1202 and will also deliver to the Trustee any Securities to
be so delivered.  Not less than 45 days before each such sinking fund payment
date, the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 1103 and cause notice of
the redemption thereof to be given in the name of and at the expense of the
Company in the manner provided in Section 1104.  Such notice having been duly
given, the redemption of such Securities shall be made upon the terms and in the
manner stated in Sections 1106 and 1107.

SECTION 1301.  Applicability of Article.
               ------------------------ 

          If, pursuant to Section 301, provision is made for the defeasance of
Securities of a series and if the Securities of such series are denominated and
payable only in Dollars (except as provided pursuant to Section 301), then the
provisions of this Article shall be applicable except as otherwise specified
pursuant to Section 301 for Securities of such series.  Defeasance provisions,
if any, for Securities denominated in a foreign currency or currency unit or for
bearer securities may be specified pursuant to Section 301.

SECTION 1302.  Defeasance Upon Deposit of
               Moneys or U.S. Government Obligations.
               ------------------------------------- 

          At the Company's option, either (a) the Company shall be deemed to
have been Discharged (as defined below) from its obligations in respect of the
Securities of any series on the 123rd day after the applicable conditions set
forth below have been satisfied or (b) the Company shall cease to be under any
obligation to comply with any provision or condition set forth in Sections 801,
802, 1004 and 1005 with respect to Securities of any series (and, if so
specified pursuant to Section 301, any other restrictive covenant added for the
benefit of such series pursuant to Section 301) and noncompliance with any such
covenant shall not result in a default in the performance, or breach, of any
covenant of the Company under this Indenture at any time after the applicable
conditions set forth below have been satisfied:

          (1) the Company shall have deposited or caused to be deposited
     irrevocably with the Trustee or its agent as trust funds in trust,
     specifically pledged as security for, and dedicated solely to, the benefit
     of the Holders of the Securities of such series:  (i) money in an amount,
     or (ii) U.S. Government Obligations (as defined below) that through the
     payment of interest and principal in respect thereof in accordance with
     their terms will provide, not later than one day before the due date of any
     payment, money in an amount, or (iii) a combination of (i) and (ii),
     sufficient, in the opinion (with respect to (ii) and (iii)) of a nationally
     recognized firm of independent public accountants expressed in a written
     certification thereof delivered to the Trustee, to pay and discharge each
     installment of principal (including any mandatory sinking fund payments)
     of, and premium, if any, and interest on, the Outstanding Securities of
     such series on the dates such installments of interest or principal and
     premium are due;

                                     -73-
<PAGE>
 
          (2) if the Securities of such series are then listed on the New York 
     Stock Exchange, the Company shall have delivered to the Trustee an Opinion
     of Counsel to the effect that the Company's exercise of the option under
     this Section 1302 would not cause the Securities to be delisted;

          (3) no Event of Default or event (including such deposit) that with
     notice or lapse of time or both would become an Event of Default with
     respect to the Securities of such series shall have occurred and be
     continuing on the date of such deposit;

          (4) the Company shall have delivered to the Trustee an Opinion of
     Counsel, which opinion and counsel are reasonably satisfactory to the
     Trustee and its counsel, to the effect that Holders of Securities of such
     series will not recognize income, gain or loss for Federal income tax
     purposes as a result of the Company's exercise of the option under this
     Section 1302 and will be subject to Federal income tax on the same amounts
     and in the same manner and at the same times as would have been the case if
     such option had not been exercised, and, in the case of Securities of such
     series being Discharged, either a private letter ruling to that effect
     received from the United States Internal Revenue Service or a revenue
     ruling pertaining to a comparable form of transaction to that effect
     published by the United States Internal Revenue Service or evidence of a
     change in applicable Federal income tax law occurring after the date of
     this Indenture; and

          (5) if the Company is to be Discharged with respect to the Securities
     of such series, no Event of Default or event which with notice or lapse of
     time or both would become an Event of Default under Section 501(6) or (7)
     with respect to the Securities of such series shall have occurred and be
     continuing at any time during the period ending on the 123rd day after the
     date of such deposit.

          "Discharged" means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by, and obligations under, the
Securities of such series and to have satisfied all the obligations under this
Indenture relating to the Securities of such series (and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging the
same), except (A) the rights of Holders of Securities of such series to receive,
from the trust fund described in subparagraph (1) above, payment of the
principal of and premium, if any, and interest on such Securities when such
payments are due; (B) the Company's obligations with respect to the Securities
of such series under Sections 305, 306, 1002, 1003, 1303 and 1304; and (C) the
rights, powers, trusts, duties and immunities of the Trustee hereunder.

issuer thereof, and shall also include a depository receipt issued by a bank or
trust company as custodian with respect to any such U.S. Government Obligation
or a specific payment of interest on or principal of any such U.S. Government
Obligation held by such custodian for the account of the holder of a depository
receipt; provided, that (except as required by law) such custodian is not
authorized to make any deduction from the amount payable to the holder of such

U.S. Government Obligation or the specific payment of interest on or principal
of the U.S. Government Obligation evidenced by such depository receipt.

pursuant to Section 1302 in respect of Securities of a series shall be held in
trust and applied by it, in accordance with the provisions of such Securities
and this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities, of all sums due and to become due
thereon for principal and premium, if any, and interest, if any, but such money
need not be segregated from other funds except to the extent required by law.

SECTION 1304.  Repayment to Company.
               --------------------

U.S. Government Obligations have been deposited pursuant to Section 1302.

          The provisions of the last paragraph of Section 1003 shall apply to
any money held by the Trustee or any Paying Agent under this Article that

for which money or U.S. Government Obligations have been deposited pursuant to
Section 1302.

   Equitable Resources, Inc.
   420 Boulevard of the Allies
   Pittsburgh, PA  15219


   Ladies and Gentlemen:

            I am Senior Vice President and Chief Legal Officer of Equitable
   Resources, Inc., a Pennsylvania corporation (the "Company"), and have acted
   as such in connection with the preparation of a Registration Statement on
   Form S-3 (the "Registration Statement") relating to the proposed offering by
   the Company of up to $168 million aggregate principal amount of debt
   securities to be issued from time to time by the Company (the "Debt
   Securities").  This opinion is furnished in connection with the filing by the
   Company of the Registration Statement.  I have examined such public and
   corporate records and documents and such questions of law, and have made such
   other investigation, as I deemed appropriate for purposes of this opinion.

            Based upon the foregoing, I am pleased to advise you that in my
   opinion the Debt Securities, when duly executed, authenticated and delivered
   pursuant to an indenture in substantially the form filed as Exhibit 4.1 to
   the Registration Statement (the "Indenture"), will be valid and binding
   obligations of the Company and, to the extent provided in the Indenture and
   the Debt Securities, enforceable in accordance with their terms, except as
   such enforceability may be limited by bankruptcy, insolvency, fraudulent
   conveyance or other laws affecting creditors' rights generally and by general
   principles of equity.

            In rendering the foregoing opinion, I have not examined the laws of
   any jurisdiction other than the laws of the Commonwealth of Pennsylvania and
   the federal laws of the United States of America and the foregoing opinion is
   limited to such laws.

            I hereby consent to the filing of this opinion as an exhibit to such
   Registration Statement and to the reference to me under the caption "Validity
   of Debt Securities" in the Prospectus contained therein.

                                           Yours truly,


                                           /s/ Augustine A.  Mazzei, Jr.
