                         DESCRIPTION OF DEBT SECURITIES
 
GENERAL
 
  The Debt Securities will be issued under an Indenture dated as of March 1,
1992, as supplemented from time to time in accordance with its terms (the
"Indenture"), between the Company and First Trust of Illinois, National
Association, as successor trustee (the "Trustee"). The following brief summary
of the Indenture and the Debt Securities is subject to the detailed provisions
of the Indenture, a copy of which is an exhibit to the Registration Statement.
Wherever references are made to particular provisions of the Indenture, such
provisions are incorporated by reference as a part of the statements made
herein and such statements are qualified in their entirety by such reference.
Certain defined terms in the Indenture are capitalized herein. References in
italics are to section numbers of the Indenture.
 
  The Indenture does not limit the amount of Debt Securities which may be
issued thereunder. It provides that Debt Securities may be issued from time to
time in series. The Debt Securities will be unsecured obligations of the
Company and will rank pari passu with all other unsecured and unsubordinated
indebtedness of the Company.
 
                                       3
<PAGE>
 
  Reference is made to the Prospectus Supplement for a description of the
following terms of the Debt Securities in respect of which this Prospectus is
being delivered: (i) the title of such Debt Securities; (ii) the limit, if any,
upon the aggregate principal amount of such Debt Securities; (iii) the dates on
which or periods during which such Debt Securities may be issued and the date
or dates on which the principal of (and premium, if any, on) such Debt
Securities will be payable; (iv) the rate or rates, if any, or the method of
determination thereof, at which such Debt Securities will bear interest, if
any; the date or dates from which such interest will accrue; the dates on which
such interest will be payable; and the regular record dates for the interest
payable on such interest payment dates; (v) the obligation, if any, of the
Company to redeem, repay or purchase such Debt Securities pursuant to any
sinking fund or analogous provisions or at the option of a holder and the
periods within which or the dates on which, the prices at which and the terms
and conditions upon which such Debt Securities will be redeemed, repaid or
purchased, in whole or in part, pursuant to such obligation; (vi) the periods
within which or the dates on which, the prices, if any, at which and the terms
and conditions upon which such Debt Securities may be redeemed, in whole or in
part, at the option of the Company; (vii) if other than denominations of $1,000
and any integral multiple thereof, the denominations in which such Debt
Securities will be issuable; (viii) whether such Debt Securities are to be

with which such Debt Securities will be issued; (ix) provisions, if any, for
the defeasance of such Debt Securities; (x) if other than United States
dollars, the currency or composite currency in which such Debt Securities are
to be denominated, or in which payment of the principal of (and premium, if
any) and interest on such Debt Securities will be made and the circumstances,
if any, when such currency of payment may be changed; (xi) if the principal of
(and premium, if any) or interest on such Debt Securities are to be payable, at
the election of the Company or a holder, in a currency or composite currency
other than that in which such Debt Securities are denominated or stated to be
payable, the periods within which, and the terms and conditions upon which,
such election may be made and the time and the manner of determining the
exchange rate between the currency or composite currency in which such Debt
Securities are denominated or stated to be payable and the currency in which
such Debt Securities are to be paid pursuant to such election; (xii) if the
amount of payments of principal of (and premium, if any) or interest on the
Debt Securities may be determined with reference to an index including, but not
limited to an index based on a currency or currencies other than that in which
such Debt Securities are stated to be payable, the manner in which such amounts
shall be determined; (xiii) whether such Debt Securities will be issued in the
form of one or more Global Securities and, if so, the identity of the
Depository for such Global Securities; (xiv) any additional Events of Default
or covenants relating solely to such Debt Securities or any Events of Default
or covenants generally applicable to Debt Securities which are not to apply to
the particular series of Debt Securities in respect of which this Prospectus is
being delivered; and (xv) any other terms of such Debt Securities not
inconsistent with the provisions of the Indenture. (Section 3.01) Unless
otherwise indicated in the applicable Prospectus Supplement, the Indenture does
not afford the holder of any series of Debt Securities the right to tender such
Debt Securities to the Company for repurchase, or provide for any increase in
the rate or rates of interest per annum at which such Debt Securities will bear
interest, in the event the Company should become involved in a highly leveraged
transaction.
 
  The Debt Securities may be issued under the Indenture bearing no interest or
interest at a rate below the prevailing market rate at the time of issuance, to
be offered and sold at a discount below their stated principal amount. Federal
income tax consequences and other special considerations applicable to any such
discounted Debt Securities or to other Debt Securities offered and sold at par
which are treated as having been issued at a discount for federal income tax
purposes will be described in the Prospectus Supplement relating thereto.
 
  A substantial portion of the assets of the Company is held by subsidiaries.
The Company's right and the rights of its creditors, including the holders of
Debt Securities, to participate in the assets of any subsidiary upon its
liquidation or recapitalization would be subject to the prior claims of such
subsidiary's creditors, except to the extent that the Company may itself be a
creditor with recognized claims against such subsidiary. There is no
restriction in the Indenture against subsidiaries of the Company incurring
unsecured indebtedness.
 
                                       4
<PAGE>
 
  Unless otherwise described in the Prospectus Supplement, the Debt Securities
will be issued only in fully registered form without coupons, in denominations
of $1,000 and multiples of $1,000, and will be payable only in United States
dollars. (Section 3.02) In addition, all or a portion of the Debt Securities of
any series may be issued in permanent registered global form which will be
exchangeable for definitive Debt Securities only under certain conditions.
(Section 2.03) The Prospectus Supplement indicates the denominations to be
issued, the procedures for payment of interest and principal thereon, and other
matters. No service charge will be made for any registration of transfer or
exchange of the Debt Securities, but the Company may, in certain instances,
require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith. (Section 3.05)
 
GLOBAL SECURITIES
 
  The Debt Securities of a particular series may be issued in the form of one
or more Global Securities which will be deposited with a Depositary, or its
nominee, each of which will be identified in the Prospectus Supplement relating
to such series. Unless and until exchanged, in whole or in part, for Debt
Securities in definitive registered form, a Global Security may not be
transferred except as a whole by the Depositary for such Global Security to a
nominee of such Depositary, 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 of such Depositary or a nominee of such successor. (Section
2.03) The specific terms of the depository arrangement with respect to any
portion of a particular series of Debt Securities to be represented by a Global
Security will be described in the Prospectus Supplement relating to such
series. The Company anticipates that the following provisions will apply to all
depository arrangements.
 
  Upon the issuance of a Global Security, the Depositary therefor or its
nominee will credit, on its book entry and registration system, the respective
principal amounts of the Debt Securities represented by such Global Security to
the accounts of such persons having accounts with such Depositary
("participants") as shall be designated by the underwriters or agents
participating in the distribution of such Debt Securities or by the Company if
such Debt Securities are offered and sold directly by the Company. Ownership of
beneficial interests in a Global Security will be limited to participants or
persons that may hold beneficial interests through participants. Ownership of
beneficial interests in a Global Security will be shown on, and the transfer of
such ownership will be effected only through, records maintained by the
Depositary therefor or its nominee (with respect to beneficial interests of
participants) or by participants or persons that hold through participants
(with respect to interests of persons other than participants). The laws of
some states require certain purchasers of securities to take physical delivery
thereof in definitive form. Such depository arrangements and such laws may
impair the ability to transfer beneficial interests in a Global Security.
 
  So long as the Depositary for a Global Security or its nominee is the
registered owner thereof, such Depositary or such nominee, as the case may be,
will be considered the sole owner or holder of the Debt Securities represented
by such Global Security for all purposes under the Indenture. Except as
provided below, owners of beneficial interests in a Global Security will not be
entitled to have Debt Securities of the series represented by such Global
Security registered in their names, will not receive or be entitled to receive
physical delivery of Debt Securities of such series in definitive form and will
not be considered the owners or holders thereof under the Indenture.
 
  Principal, premium, if any, and interest payments on a Global Security
registered in the name of a Depositary or its nominee will be made to such
Depositary or nominee, as the case may be, as the registered owner of such
Global Security. None of the Company, the Trustee or any paying agent for Debt
Securities of the series represented by such Global Security will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial interests in such Global Security or for
maintaining, supervising or reviewing any records relating to such beneficial
interests.
 
  The Company expects that the Depositary for a Global Security or its nominee,
upon receipt of any payment of principal, premium or interest, will immediately
credit participants' accounts with payments in
 
                                       5
<PAGE>
 
amounts proportionate to their respective beneficial interests in the principal
amount of such Global Security as shown on the records of such Depositary or
its nominee. The Company also expects that payments by participants to owners
of beneficial interests in such Global Security held through such participants
will be governed by standing instructions and customary practices, as is now
the case with securities held for the accounts of customers registered in
"street name," and will be the responsibility of such participants.
 
  If the Depositary for a Global Security representing Debt Securities of a
particular series is at any time unwilling or unable to continue as Depositary
and a successor Depositary is not appointed by the Company within 90 days, the
Company will issue Debt Securities of such series in definitive form in
exchange for such Global Security. In addition, the Company may at any time and
in its sole discretion determine not to have the Debt Securities of a
particular series represented by one or more Global Securities and, in such
event, will issue Debt Securities of such series in definitive form in exchange
for all of the Global Securities representing Debt Securities of such series.

(Section 6.02)
 
  "Significant Subsidiary" is defined in the Indenture to mean any Subsidiary

Securities shall have occurred and be continuing, either the Trustee or the
Holders of at least 25% in aggregate principal amount of the Debt Securities
then outstanding may declare the entire principal and accrued interest of all
Debt Securities to be due and payable immediately. However, any time after a
declaration of acceleration with respect to the Debt Securities has been made,
but before a judgment or decree for the payment of money based on such
acceleration has been obtained by the Trustee, the Holders of a majority in
principal amount of the Outstanding Debt Securities, may, under certain
circumstances, rescind and annul such acceleration. The Holders of a majority
in principal amount of the Outstanding Debt Securities may waive any past
defaults under the Indenture with respect to the Debt Securities, except
defaults in payment of principal of or premium, if any (other than by a
declaration of acceleration), or interest on the Debt Securities or covenants
that may not be modified or amended without the consent of the Holders of all
Outstanding Debt Securities. (Sections 5.02 and 5.13)

proceedings, judicial or otherwise, with respect to the Indenture or any remedy
thereunder unless, among other things, the Holder or Holders of Debt Securities
shall have offered to the Trustee reasonable indemnity against costs, expenses
and liabilities relating to such proceedings. (Sections 5.12 and 5.07)
 
MODIFICATION OF THE INDENTURE
 
  With respect to the Debt Securities, modification or amendment of the
Indenture may be made by the Company and the Trustee with the consent of the
Holders of a majority in aggregate principal amount of the Debt Securities,
except that no such modification or amendment may, without the consent of the
Holders of all then Outstanding Debt Securities (i) change the due date of the
principal of, or any installment of principal of or interest on, any Debt
Securities; (ii) reduce the principal amount of, or rate of interest on, or any
premium payable on redemption of any Debt Securities; (iii) reduce the
principal amount of any Debt Securities payable upon acceleration of the
maturity thereof; (iv) change the place or the currency of payment of principal
of, or any premium or interest on, any Debt Securities; (v) impair the right to
institute suit for the enforcement of any payment on or with respect to any

of whose holders is required for modification or amendment of the Indenture or
for waiver of compliance with certain provisions of the Indenture or for waiver
of certain defaults; or (vii) modify certain provisions of the Indenture
regarding the amendment or modification of, or waiver with respect to, any
provision of the Indenture or the Debt Securities. (Section 9.02)
 
DEFEASANCE
 
  If provision is made pursuant to Section 3.01 of the Indenture for the
defeasance of a series of Debt Securities, and if such series is payable only
in United States dollars (unless otherwise specifically provided), the Company,
at its option, in respect of such series of Debt Securities (i) will be
discharged from any and all obligations in respect of such Debt Securities
(except for certain obligations to register the transfer or exchange of Debt
Securities, replace stolen, lost or mutilated Debt Securities, maintain paying
agencies and hold moneys for payment in trust and obligations with respect to
subordination) or (ii) will not be subject to provisions of the Indenture
described above under "Consolidation, Merger and Sale of Assets," "Limitation
on Indebtedness Secured by a Mortgage," and "Limitation on Sale and Lease-Back
Transactions" if the Company deposits with the Trustee, in trust, money or U.S.
Government Obligations which through the payment of interest thereon and
principal thereof in accordance with their terms will provide money in an
amount sufficient to pay all the principal of, and interest on, such Debt
Securities on the dates such payments are due in accordance with the terms of
such Debt Securities. To exercise any such option, the Company is required to
deliver to the Trustee (x) an opinion of a nationally recognized tax counsel to
the effect that the deposit and related defeasance would not cause the holders
of the Debt Securities to recognize income, gain or loss for federal income tax
purposes as a result of the Company's exercise of its option and (y) if the
Debt Securities are then listed on the New York Stock Exchange (the "NYSE"), an
opinion of counsel to the effect that the Debt Securities would not be delisted
from the NYSE as a result of the exercise of such option. (Sections 13.01 and
13.02)
 
THE TRUSTEE
 
  First Trust of Illinois, National Association is the Trustee under the
Indenture. The Trustee is a depository for funds of and performs other services
for and transacts other banking business with the Company in the normal course
of business. The Trustee also acts as trustee under (i) the indenture relating

amount of which were outstanding as of March 31, 1996 and (ii) the Indenture
pursuant to which there were $253,000,000 aggregate principal amount of the
Company's Medium-Term Notes, Series C outstanding as of March 31, 1996.

                            DESCRIPTION OF WARRANTS
 
  The following description of the terms of the Warrants sets forth certain
general terms and provisions of the Warrants to which any Prospectus Supplement
may relate. The particular terms of the Warrants offered by any Prospectus
Supplement and the extent, if any, to which such general provisions may apply
to the Warrants so offered will be described in the Prospectus Supplement
relating to such Warrants.
 
GENERAL
 
  Warrants may be offered together with any series of Debt Securities offered
by a Prospectus Supplement and if so offered will be attached to such Debt
Securities and will entitle the holder thereof to purchase additional Debt
Securities having the same terms and interest rate as the offered Debt
Securities. Each series of Warrants will be issued under a separate warrant
agreement (a "Warrant Agreement") to be entered into between the Company and a
bank or trust company, as warrant agent (the "Warrant Agent"), all as described
in the Prospectus Supplement relating to such series of Warrants. The Warrant
Agent will act solely as the agent of the Company under the applicable Warrant
Agreement and in connection with the certificates for the Warrants (the
"Warrant Certificates") of such series, and will not assume any obligation or
relationship of agency or trust for or with any holders of such Warrant
Certificates or beneficial owners of Warrants. A copy of the form of Warrant
Agreement, including the form of Warrant Certificates, is filed as an exhibit
to the Registration Statement. The following summary of certain provisions of
the forms of Warrant Agreement and Warrant Certificates does not purport to be
complete and is subject to, and is qualified in its entirety by reference to,
all the provisions of the Warrant Agreement and the Warrant Certificates.
 
  Reference is hereby made to the Prospectus Supplement relating to the
particular series of Warrants, if any, offered thereby for the terms of such
Warrants, including, where applicable: (i) the offering price; (ii) the
currency or currencies in which such Warrants are being offered; (iii) the
designation, aggregate principal amount, currency or currencies, denominations
and other terms of the series of Debt Securities purchasable upon exercise of
such Warrants; (iv) the designation and terms of the series of Debt Securities
with which such Warrants are being offered and the number of such Warrants
being offered with each such Debt Security; (v) the date on and after which
such Warrants and the related series of Debt Securities will be transferable
separately; (vi) the principal amount of the Debt Securities purchasable upon
exercise of each such Warrant and the price at which and currency or currencies
in which such principal amount of Debt Securities may be purchased upon such
exercise; (vii) the date on which the right to exercise such Warrants shall
commence (the "Exercise Date") and the date on which such right shall expire
(the "Expiration Date"); and (viii) any other terms of such Warrants not
inconsistent with the applicable Warrant Agreement.
 
  Warrants of any series will be exchangeable into Warrants of the same series
representing in the aggregate the number of Warrants surrendered for exchange.
Warrant Certificates may be presented for exchange or transfer at the corporate
trust office of the Warrant Agent for such series of Warrants (or any other
office indicated in the Prospectus Supplement relating to such series of
Warrants). Prior to the exercise of their Warrants, holders of Warrants will
not have any of the rights of holders of the series of Debt Securities
purchasable upon such exercise, including the right to receive payments of
principal of, premium, if any, or interest, if any, on the Debt Securities
purchasable upon such exercise, or to enforce any of the covenants in the
Indenture.
 
EXERCISE OF WARRANTS
 
  Each Warrant will entitle the holder thereof to purchase such principal
amount of the related series of Debt Securities at such exercise price as shall
in each case be set forth in, or calculable as set forth in, the Prospectus
Supplement relating to such Warrant. Warrants of a series may be exercised at
the corporate trust office of the Warrant Agent for such series (or any other
office indicated in the Prospectus Supplement relating to such series) at any
time on or after the Exercise Date and prior to 5:00 P.M., Chicago time (unless
otherwise indicated in the related Prospectus Supplement), on the Expiration

                                       10
<PAGE>
 
Supplement relating to such series of Warrants. After the close of business on
the Expiration Date relating to such series of Warrants, unexercised Warrants
of such series will be void.
 
  Warrants of a series may be exercised by delivery to the appropriate Warrant
Agent of payment, as provided in the Prospectus Supplement relating to such
series of Warrants, of the consideration required to purchase the principal
amount of the series of Debt Securities purchasable upon such exercise,
together with certain information as set forth on the reverse side of the
Warrant Certificate evidencing such Warrants. Such Warrants will be deemed to
have been exercised upon receipt of the exercise price, subject to the receipt
of the Warrant Certificate evidencing such Warrants within five business days.
Upon receipt of such payment and such Warrant Certificate, properly completed
and duly executed, at the corporate trust office of the appropriate Warrant
Agent (or any other office indicated in the Prospectus Supplement relating to
such series of Warrants), the Company will, as soon as practicable, issue and
deliver the principal amount of the series of Debt Securities purchasable upon
such exercise. If fewer than all of the Warrants represented by a Warrant
Certificate are exercised, a new Warrant Certificate will be issued and
delivered for the remaining amounts of Warrants.
 
                              PLAN OF DISTRIBUTION
 
  The Company may sell the Securities in any of three ways: (i) to or through
underwriters or dealers, (ii) through agents or (iii) directly to one or more
purchasers. With respect to each series of Securities being offered hereby, the
terms of the offering of the Securities of such series, including the name or
names of any underwriters or agents, the purchase price of such Securities and
the proceeds to the Company from such sale, any underwriting discounts, selling
commissions and other items constituting underwriters', dealers' or agents'
compensation, any initial public offering price and any discounts or
concessions allowed or reallowed or paid to dealers or agents, and any
securities exchanges on which the Securities of such series may be listed, will
be set forth in, or may be calculated from the information set forth in, the
Prospectus Supplement. Only underwriters so named in the Prospectus Supplement
are deemed to be underwriters in connection with the Securities offered
thereby.
 
  If underwriters are used in the sale, the Securities will be acquired by the
underwriters for their own account and may be resold from time to time in one
or more transactions, including negotiated transactions, at a fixed public
offering price or at varying prices determined at the time of sale. The
Securities may be offered to the public either through underwriting syndicates
represented by managing underwriters or by underwriters without a syndicate.
Unless otherwise set forth in the Prospectus Supplement, the obligations of the
underwriters to purchase Securities will be subject to certain conditions
precedent and the underwriters will be obligated to purchase all the securities
offered by the Prospectus Supplement if any of such Securities are purchased.
Any initial public offering price and any discounts or concessions allowed or
reallowed or paid to dealers may be changed from time to time.
 
  Securities may also be sold directly by the Company or through agents (who
may also act as principals) designated by the Company from time to time. Any
agent involved in the offer or sale of the Securities in respect of which this
Prospectus is delivered will be named, and any commissions payable by the
Company to such agent will be set forth in, or may be calculated from the
information set forth in, the Prospectus Supplement. Unless otherwise indicated
in the Prospectus Supplement, any such agent will be acting on a best efforts
basis for the period of its appointment. In the case of sales made directly by
the Company, no commission will be payable.
 
  If so indicated in the Prospectus Supplement, the Company will authorize
agents, underwriters or dealers to solicit offers by certain specified
institutions to purchase Securities from the Company at the public offering
price set forth in the Prospectus Supplement pursuant to delayed delivery
contracts providing for payment and delivery on a future date specified in the
Prospectus Supplement. Such contracts will be subject to the
 
                                       11
<PAGE>
 
conditions set forth in the Prospectus Supplement, and the Prospectus
Supplement will set forth the commissions payable for solicitation of such
contracts.
 
  Agents and underwriters may be entitled under agreements entered into with
the Company to indemnification by the Company against certain civil
liabilities, including liabilities under the Securities Act of 1933, as
amended, or to contribution with respect to payments which the agents or
underwriters may be required to make in respect thereof. Agents and
underwriters may be customers of, engage in transactions with, or perform
services for the Company or its affiliates in the ordinary course of business.
 
  In the event that the Securities of any series are not listed on a national
securities exchange, certain broker-dealers may make a market in the Securities
of such series, but will not be obligated to do so and may discontinue any
market making at any time without notice. No assurance can be given that any
broker-dealer will make a market in the Securities or as to the liquidity of
the trading market for the Securities. The Prospectus Supplement with respect
to the Securities of any series will state, if known, whether or not any
broker-dealer intends to make a market in such Securities. If no such
determination has been made, the Prospectus Supplement will so state.

(the "DGCL") provide that the Company may indemnify the directors and officers
of the Company and affiliated companies against liabilities and expenses
incurred by reason of the fact that such persons were serving in such
capacities, subject to certain limitations and conditions set forth in the
statute. Article TWELFTH of the Company's Restated Certificate of Incorporation
provides that the Company shall indemnify its directors and officers to the
fullest extent permitted by Delaware law. In accordance with Section 102(b)(7)
of the DGCL, the Company's Restated Certificate of Incorporation provides that
no directors of the Company shall be personally liable to the Company or its
stockholders for monetary damages for breach of fiduciary duty as a director
except for (i) breach of the director's duty of loyalty to the Company or its
stockholders, (ii) acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) unlawful payment of
dividends under Section 174 of the DGCL or (iv) transactions from which the
director derives an improper personal benefit.
 
  Pursuant to Section 145 of the DGCL and the Company's Restated Certificate of
Incorporation, the directors and officers of the Company are covered by
Directors and Officers Liability and Corporation Reimbursement insurance
policies.
 
  Reference is made to Section 7 of the form of Underwriting Agreement (filed
as Exhibit 1.1 to this Registration Statement) and Section 8 of the form of
Selling Agency Agreement (filed as Exhibit 1.2 to this Registration Statement),
which provide for indemnification of directors and officers of the Company
against certain liabilities, including liabilities under the Securities Act of
1933, in certain circumstances.

ITEM 17. UNDERTAKINGS.
 
  The Registrant hereby undertakes:
 
    (1) To file, during any period in which offers or sales are being made of
  the securities registered hereby, a post-effective amendment to this
  Registration Statement:
 
      (i) To include any prospectus required by Section 10(a)(3) of the
    Securities Act of 1933;
 
      (ii) To reflect in the prospectus any facts or events arising after
    the effective date of this 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 this 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 end of the estimated
    maximum offering range may be reflected in the form of prospectus filed
    with the Commission pursuant to Rule 424(b) if, in the aggregate, the
    changes in volume and price represent no more than a 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 this Registration Statement or
    any material change to such information in this Registration Statement;
 
  provided, however, that the undertakings set forth in paragraphs (i) and
  (ii) above do not apply if the information required to be included in a
  post-effective amendment by those paragraphs is contained in periodic
  reports filed by the Registrant pursuant to Section 13 or Section 15(d) of
  the Securities Exchange Act of 1934 that are incorporated by reference in
  this Registration Statement.
 
    (2) That, for the purpose of determining any liability under the
  Securities Act of 1933, 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.
 
                                      II-2
<PAGE>
 
    (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.
 
    (4) That, for purposes of determining any liability under the Securities
  Act of 1933, each filing of the Registrant's annual report pursuant to
  Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and,
  where applicable, each filing of an employee benefit plan's annual report
  pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is
  incorporated by reference in this Registration Statement shall be deemed to
  be a new registration statement relating to the securities offered therein,
  and the offering of such securities at that time shall be deemed to be the
  initial bona fide offering thereof.
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 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 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 Act and will be governed by the final adjudication of such
issue.

          (a) The Company meets the requirements for use of Form S-3 under the
     Securities Act of 1933, as amended (the "Act"), and has filed with the
     Securities and Exchange Commission (the "Commission") a registration
     statement on such Form (the file number of which is set forth in Schedule I
     hereto), which has become effective, for the registration under the Act of
     the Securities. Such registration statement, as amended at the date of this
     Agreement, meets the requirements set forth in Rule 415(a)(1)(x) under the
     Act and complies in all other material respects with said Rule. The Company
     proposes to file with the Commission pursuant to Rule 424 under the Act a
     supplement to the form of prospectus included in such registration
     statement relating to the Securities and the plan of distribution thereof
     and has previously advised you of all further information (financial and
     other) with respect to the Company to be set forth therein. Such
     registration statement, including the exhibits thereto, as amended at the
     date of this Agreement is hereinafter called the "Registration Statement";
     such prospectus in the form in which it appears in the Registration
     Statement is hereinafter called the "Basic Prospectus"; and such
     supplemented form of prospectus, in the form in which it shall be filed
     with the Commission pursuant to Rule 424 (including the Basic Prospectus as
     so supplemented) is hereinafter called the "Final Prospectus". Any
     preliminary form of the Final Prospectus, which has heretofore been filed
     pursuant to Rule 424 is hereinafter called the "Preliminary Final
     Prospectus." Any reference herein to the Registration Statement, the Basic
     Prospectus, any Preliminary Final Prospectus or the Final Prospectus shall
     be deemed to refer to and include the documents incorporated by reference
     therein pursuant to Item 12 of Form S-3 which were filed under the
     Securities Exchange Act of 1934, as amended (the "Exchange Act"), on or
     before the date of this Agreement, or the issue date of the Basic
     Prospectus, any Preliminary Final Prospectus or the Final Prospectus, as
     the case may be; and any reference herein to the terms "amend", "amendment"
     or "supplement" with respect to the Registration Statement, the Basic
     Prospectus, any Preliminary Final Prospectus or the Final Prospectus shall
     be deemed to refer to and include the filing of any document under the
     Exchange Act after the date of this Agreement, or the issue date of the
     Basic Prospectus, any Preliminary Final Prospectus or the Final Prospectus,
     as the case may be, deemed to be incorporated therein by reference.

          (b) (i) As of the date hereof, (ii) when the Final Prospectus is first
     filed or transmitted for filing pursuant to Rule 424 under the Act, (iii)
     when, prior to the Closing Date (as hereinafter defined in Section 3), any
     amendment to the Registration Statement becomes effective (including the
     filing of any document incorporated by reference in the Registration
     Statement), (iv) when any supplement to the Final Prospectus is filed with
     the Commission and (v) at the Closing Date: (x) the Registration Statement,
     as amended as of any such time, and the Final Prospectus, as amended or
     supplemented as of any such time, and the Indenture will comply in all
     material respects with the applicable requirements of the Act, the Trust
     Indenture Act of 1939, as amended (the "Trust Indenture Act"), and the
     Exchange Act and the respective rules thereunder, (y) the Registration
     Statement, as amended as of any such time, will not contain any untrue
     statement of a material fact or omit to state any material fact required to
     be stated therein


                                      -2-
<PAGE>
 
     or necessary in order to make the statements therein not misleading and (z)
     the Final Prospectus, as amended or supplemented as of any such time, will
     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 light
     of the circumstances under which they were made, not misleading; provided,
     however, that the Company makes no representations or warranties as to (x)
     that part of the Registration Statement which shall constitute the
     Statement of Eligibility (Form T-1) under the Trust Indenture Act of the
     Trustee or (y) any information contained in or omitted from the
     Registration Statement or the Final Prospectus or any amendment thereof or
     supplement thereto in reliance upon and in conformity with information
     furnished in writing to the Company by or on behalf of any Underwriter
     through the Representatives specifically for use in connection with the
     preparation of the Registration Statement and the Final Prospectus.

          (c) As of the date hereof and at the Closing Date:

               (i) each of the Company and Chicago Tribune Company, Sentinel
          Communications Company, Sun-Sentinel Company and Tribune Broadcasting
          Company (individually, a "Designated Subsidiary" and collectively, the
          "Designated Subsidiaries") has been duly incorporated and is validly
          existing as a corporation in good standing under the laws of the
          jurisdiction in which it is chartered or organized, with full
          corporate power and authority to own its properties and conduct its
          business as described in the Basic Prospectus (as of the date hereof)
          or the Final Prospectus (as of the Closing Date), and is duly
          qualified or licensed to do business as a foreign corporation and is
          in good standing under the laws of each jurisdiction where the
          character of the properties owned or leased or the nature of the
          activities conducted by such corporations, respectively, makes such
          qualifications or licensing necessary, and where the failure to be so
          qualified or licensed might materially adversely affect the financial
          condition, assets, operations or prospects of the Company and its
          subsidiaries considered as one enterprise;

               (ii) all the outstanding shares of capital stock of each
          Designated Subsidiary have been duly and validly authorized and issued
          and are fully paid and nonassessable, and, except as otherwise set
          forth in the Basic Prospectus (as of the date hereof) or the Final
          Prospectus (as of the Closing Date), all outstanding shares of capital
          stock of the Designated Subsidiaries are owned by the Company either
          directly or through wholly owned subsidiaries free and clear of any

          Securities] [2: Units] have been duly authorized and, when executed
          and authenticated in accordance with the provisions of the Indenture

          relating to or affecting the enforcement of creditor's rights or by

          sale of the [1: Securities] [2: Notes], the consummation of any other
          of the transactions herein contemplated or the fulfillment of the
          terms hereof will conflict with, result in a breach of, or constitute
          a default under the charter or by-laws of the Company or the terms of
          any indenture or other agreement or instrument to which the Company or
          any of the Designated Subsidiaries is a party or bound, or any order,
          decree, rule or regulation known to the Company to be applicable to

          (d) The Company confirms as of the date hereof, and at the Closing
     Date, that the Company is in compliance with all provisions of Section 1 of
     Laws of Florida, Chapter 92-198, An Act Relating to Disclosure of Doing
     Business with Cuba, and the Company further agrees that if it commences
     engaging in business with the government of Cuba or with any person or
     affiliate located in Cuba after the date the Registration Statement becomes
     or has become effective with the Commission or with the Florida Department
     of Banking and Finance (the "Department"), whichever date is later, or if
     the information reported in the Basic, Preliminary Final or the Final
     Prospectus, if any, concerning the Company's business with Cuba or with any
     person or affiliate located in Cuba changes in any material way, the
     Company will provide the Department notice of such business or change, as
     appropriate, in a form acceptable to the Department.

     2. PURCHASE AND SALE. Subject to the terms and conditions and in reliance
upon the representations and warranties herein set forth, the Company agrees to
sell to each Underwriter, and each Underwriter agrees, severally and not
jointly, to purchase from the Company, at the purchase price set forth in
Schedule I hereto, the [1: principal amount of the Securities] [2: number of
Units] set forth opposite such Underwriter's name in Schedule II hereto except
that, if Schedule I hereto provides for the sale of [1: Securities] [2: Units]
pursuant to delayed delivery arrangements, the respective [1: principal amounts
of Securities] [2: numbers of Units] to be purchased by the Underwriters shall
be as set forth in Schedule II hereto less the respective amounts of Contract
Securities determined as provided below. [1: Securities] [2: Units] to be
purchased by the Underwriters are herein sometimes called the "Underwriters'
Securities" and [1: Securities] [2: Units] to be purchased pursuant to Delayed
Delivery Contracts as hereinafter provided are herein called "Contract
Securities".

     If so provided in Schedule I hereto, the Underwriters are authorized to
solicit offers to purchase [1: Securities] [2: Units] from the Company pursuant
to delayed delivery contracts ("Delayed Delivery Contracts"), substantially in
the form of Schedule III hereto but with such changes therein as the Company may
authorize or approve. The Underwriters will endeavor to make such arrangements
and, as compensation therefor, the Company will pay to the Representatives, for
the account of the Underwriters, on the Closing Date, the percentage set forth
in Schedule I hereto of the [1: principal amount of the Securities] [2: number
of units] for

                                      -5-
<PAGE>
 
which Delayed Delivery Contracts are made. Delayed Delivery Contracts are to be
with institutional investors, including commercial and savings banks, insurance
companies, pension funds, investment companies and educational and charitable
institutions. The Company will enter into Delayed Delivery Contracts in all
cases where sales of Contract Securities arranged by the Underwriters have been
approved by the Company but, except as the Company may otherwise agree, each
such Delayed Delivery Contract must be for not less than the minimum [1:
principal amount] [2: number] set forth in Schedule I hereto and the [1:
aggregate principal amount] [2: number] of Contract Securities may not exceed
the maximum aggregate [1: principal amount] [2: number] set forth in Schedule I
hereto. The Underwriters will not have any responsibility in respect of the
validity or performance of Delayed Delivery Contracts. The [1: principal amount
of Securities] [2: number of Units] to be purchased by each Underwriter as set
forth in Schedule II hereto shall be reduced by an amount which shall bear the
same proportion to the total [1: principal amount] [2: number] of Contract
Securities as the [1: principal amount of Securities] [2: number of Units] set
forth opposite the name of such Underwriter bears to the aggregate [1: principal
amount] [2: number] set forth in Schedule II hereto, except to the extent that
you as Representatives determine that such reduction shall be otherwise than in
such proportion and so advise the Company in writing; provided, however, that
the total [1: principal amount of Securities] [2: number of Units] to be
purchased by all Underwriters shall be the aggregate [1: principal amount] [2:
number] set forth in Schedule II hereto less the aggregate principal amount of
Contract Securities.

     3.   DELIVERY AND PAYMENT. Delivery of and payment for the Underwriters'
Securities shall be made at the location, in the currency, on the date and at
the time specified in Schedule I hereto (or such later date not later than five
business days after such specified date as the Representatives shall designate),
which date and time may be postponed by agreement between the Representatives
and the Company as provided in Section 8 hereof (such date and time of delivery
and payment for the Underwriters' Securities being herein called the "Closing
Date"). Delivery of the Underwriters' Securities shall be made to the
Representatives for the respective accounts of the several Underwriters against
payment by the several Underwriters through the Representatives of the purchase
price thereof to or upon the order of the Company by certified or official bank
check or checks payable in Chicago Clearing House (next day) funds. Certificates
for the Underwriters' Securities shall be registered in such names and in such
denominations as the Representatives may request not less than three full
business days in advance of the Closing Date.

     The Company agrees to have the Underwriters' Securities available for
inspection, checking and packaging by the Representatives in New York, New York,
not later than 1:00 p.m. on the business day prior to the Closing Date, except
as otherwise provided in Schedule I hereto.

     4.   AGREEMENTS.  The Company agrees with the several Underwriters that:

          (a) Prior to the termination of the offering of the [1: Securities]
     [2: Units], the Company will not file any amendment of the Registration
     Statement or supplement

                                      -6-

<PAGE>
 
     (including the Final Prospectus) to the Basic Prospectus [2: , and prior to
     the exercise or expiration of all the Warrants, the Company will not file
     any such amendment or supplement relating to the Warrant Debt Securities,]
     unless the Company has furnished to the Representatives for their review a
     copy thereof prior to filing. Subject to the foregoing sentence, the
     Company will cause the Final Prospectus to be filed (or transmitted for
     filing) with the Commission pursuant to Rule 424. The Company will promptly
     advise the Representatives (i) when the Final Prospectus shall have been
     filed (or transmitted for filing) with the Commission pursuant to Rule 424,
     (ii) when any amendment to the Registration Statement relating to the
     Securities shall have become effective, (iii) of any request by the
     Commission for any amendment of the Registration Statement or amendment of
     or supplement to the Final Prospectus or for any additional information,
     (iv) of the issuance by the Commission of any stop order suspending the
     effectiveness of the Registration Statement or the institution or
     threatening of any proceeding for that purpose and (v) of the receipt by
     the Company of any notification with respect to the suspension of the
     qualification of [2: any of] the Securities for sale in any jurisdiction or
     the initiation or threatening of any proceeding for such purpose. The
     Company will use its best efforts to prevent the issuance of any such stop
     order and, if issued, to obtain as soon as possible the withdrawal thereof.

          (b) If, at any time when a prospectus relating to the Securities is
     required to be delivered under the Act, any event occurs as a result of
     which the Final Prospectus as then amended or supplemented would include
     any untrue statement of a material fact or omit to state any material fact
     necessary to make the statements therein in the light of the circumstances
     under which they were made not misleading, or if it shall be necessary to
     amend or supplement the Final Prospectus to comply with the Act, the
     Exchange Act or the Trust Indenture Act or the respective rules thereunder,
     the Company promptly will prepare and file with the Commission, subject to
     the first sentence of subparagraph (a) of this Section 4, an amendment or
     supplement which will correct such statement or omission or an amendment
     which will effect such compliance.

          (c) As soon as practicable, the Company will make generally available
     to its security holders and to the Representatives an earnings statement or
     statements (which need not be audited) of the Company and its subsidiaries
     which will satisfy the provisions of Section 11(a) of the Act and Rule 158
     under the Act.

          (d) The Company will furnish to each of the Representatives and to
     counsel for the Underwriters, without charge, one signed copy of the
     Registration Statement (including exhibits thereto) and to each other
     Underwriter a conformed copy of the Registration Statement (without
     exhibits thereto) and each amendment thereto which shall become effective
     on or prior to the Closing Date and, so long as delivery of a prospectus by
     an Underwriter or dealer may be required by the Act, as many copies of each
     Preliminary Final Prospectus and the Final Prospectus and any amendments
     thereof and

                                      -7-
<PAGE>
 
     supplements thereto as the Representatives may reasonably request. The
     Company will pay the expenses of printing all documents relating to the
     offering.

          (e) The Company will arrange for the qualification of the Securities
     for sale under the laws of such jurisdictions as the representatives may
     designate, will maintain such qualifications in effect so long as required
     for the distribution of the Securities, will arrange for the determination
     of the legality of the Securities for purchase by institutional investors
     and will pay the fee of the National Association of Securities Dealers,
     Inc., if any, in connection with its review of the offering; provided,
     however, that the Company shall not be required to effect or maintain any
     such qualification in any jurisdiction that would result in it having to
     execute or file a general consent to service of process under the laws of
     such jurisdiction or to qualify to do business as a foreign corporation in
     such jurisdiction.

          (f) Until the business day following the Closing Date, the Company 
     will not, without the consent of the Representatives, offer, sell or
     contract to sell, or announce the offering of, any debt securities or
     warrants to purchase debt securities covered by the Registration Statement
     or any other registration statement filed under the Act.

     5.   CONDITIONS TO THE OBLIGATIONS OF THE UNDERWRITERS.  The obligations of
the Underwriters to purchase the Underwriters' Securities shall be subject to

          (b) The Company shall have furnished to the Representatives the 
     opinion of Sidley & Austin, special counsel for the Company, dated the
     Closing Date, to the effect that:

               (i) each of the Company and the Designated Subsidiaries has been
          duly incorporated and is validly existing as a corporation in good
          standing under the laws of the jurisdiction in which it is chartered
          or organized, with full corporation power and authority to own its
          properties and conduct its business as described in the Final
          Prospectus;

               (ii) all the outstanding shares of capital stock of each
          Designated Subsidiary have been duly and validly authorized and issued
          and are fully paid and nonassessable, and, to the knowledge of such
          counsel, except as otherwise set forth in the Final Prospectus, all
          outstanding shares of capital stock of the Designated Subsidiaries are
          owned by the Company either directly or through wholly owned
          subsidiaries free and clear of any security interests, claims, liens
          or encumbrances;

               (iii) the Securities and the Indenture conform in all material
          respects to the description thereof contained in the Final Prospectus;
          the holders of outstanding shares of capital stock of the Company are
          not entitled to rights to subscribe for the Securities;

               (iv) the Indenture [2: and the Warrant Agreement] has [2: have]
          been duly authorized, executed and delivered by the Company, and
          constitute[s a] legal, valid and binding instrument[s] enforceable
          against the Company in accordance with [1: its] [2: their] terms
          except as enforcement thereof may be limited by bankruptcy,
          insolvency, reorganization, moratorium or other laws of general
          applicability relating to or affecting the enforcement of creditors'
          rights or by the effect of general principles of equity (regardless of
          whether enforceability is considered in a proceeding in equity or at
          law); the Indenture has been duly qualified under the Trust Indenture
          Act; and the Securities have been duly authorized and, when executed
          and authenticated [2: or countersigned] in accordance with the
          provisions of the Indenture [2: or the Warrant Agreement, as the case
          may be,] and the procedures adopted by the Special Committee thereof
          and delivered to and paid for by the Underwriters pursuant to this
          Agreement, in the case of the Underwriters' Securities, or by the
          purchasers thereof pursuant to Delayed Delivery Contracts, in the case
          of any Contract Securities, [2: or by the purchasers thereof pursuant
          to the Warrant Agreement, in the case of the Warrant Debt Securities]
          will constitute legal, valid and binding obligations of the Company
          except as enforcement thereof may be limited by bankruptcy,
          insolvency, reorganization, moratorium or other laws of general
          applicability relating to or affecting the enforcement of creditors'
          rights or by the effect of general principles of equity (regardless of
          whether enforceability is considered in a proceeding in equity or at
          law) and will be entitled to the benefits of the Indenture [2: or the
          Warrant Agreement, as the case may be];

               (v) to the knowledge of such counsel, there is no pending or
          threatened action, suit or proceeding before any court or governmental
          agency, authority or body or any arbitrator involving the Company or
          any of its Designated Subsidiaries of a character required to be
          disclosed in the Registration Statement which is not adequately
          disclosed in the Final Prospectus, and there is no franchise, contract
          or other document of a character required to be described in the
          Registration

                                      -9-
<PAGE>
 
          Statement or Final Prospectus, or to be filed as an exhibit to the
          Registration Statement, which is not described or filed as required;
          and the statements included or incorporated in the Final Prospectus
          with respect to any such action, suit, proceeding, franchise, contract
          or other document fairly summarize the matters required to be
          disclosed or described;

               (vi) the Registration Statement and any amendments thereto have
          become effective under the Act; to the best knowledge of such counsel,
          no stop order suspending the effectiveness of the Registration
          Statement, as amended, has been issued, no proceedings for that
          purpose have been instituted or threatened; the Registration
          Statement, the Final Prospectus and each amendment thereof or
          supplement thereto as of their respective effective or issue dates
          (other than the financial statements, financial data, statistical data
          and supporting schedules included or incorporated by reference
          therein, as to which such counsel need express no opinion) complied as
          to form in all material respects with the applicable requirements of
          the Act and the Exchange Act and the respective rules thereunder; and
          although such counsel has not independently verified, is not passing
          upon and assumes no responsibility for the accuracy, completeness or
          fairness of statements contained in the Registration Statement or any
          amendment thereof or the Final Prospectus or any amendment or
          supplement thereof, except as noted above, nor has such counsel
          verified the computation or compilation of financial statements and
          other financial data, nothing has come to such counsel's attention
          which causes such counsel to believe that the Registration Statement
          or any amendment thereof (other than the financial statements,
          financial data, statistical data and supporting schedules, as to which
          such counsel need express no belief), at the time it became effective
          and at the date of this Agreement, contained any untrue statement of a
          material fact or omitted to state any material fact required to be
          stated therein or necessary to make the statements therein not
          misleading or that the Final Prospectus, as amended or supplemented
          (other than the financial statements, financial data, statistical data
          and supporting schedules, as to which such counsel need express no
          belief), at the Closing Date, includes any untrue statement of a
          material fact or omits to state a material fact necessary to make the
          statements therein, in the light of the circumstances under which they
          were made, not misleading;

               (vii) this Agreement and any Delayed Delivery Contracts have been
          duly authorized, executed and delivered by the Company;

               (viii) no consent, approval, authorization or order of any court
          or governmental agency or body, domestic or foreign, is required for
          the consummation of the transactions contemplated herein or in any
          Delayed Delivery Contracts except such as have been obtained under the
          Act and such as may be required under the blue sky laws of any
          jurisdiction in connection with the

                                     -10-
<PAGE>
 
           purchase and distribution of the Securities by the Underwriters and
           such other approvals (specified in such opinion) as have been
           obtained;

               (ix) neither the execution of the Indenture, the issuance and 
          sale of the Securities, nor the consummation of any other of the
          transactions herein contemplated or the fulfillment of the terms
          hereof or of any Delayed Delivery Contracts will result in a breach
          of, or constitute a default under, the charter or by-laws of the
          Company or the terms of any indenture or other material agreement or
          instrument known to such counsel and to which the Company or any of
          its Designated Subsidiaries is a party or bound, or any order, decree,
          rule or regulation known to such counsel to be applicable to the
          Company or any of its Designated Subsidiaries of any court, regulatory
          body, administrative agency, governmental body or arbitrator, domestic
          or foreign, having jurisdiction over the Company or any of its
          Designated Subsidiaries;

               (x) no holders of outstanding securities of the Company have 
          rights to the registration of such securities under the Registration
          Statement; and

               (xi) if the Securities are to be listed on any stock exchange,
          authorization therefor has been given, subject to official notice of
          issuance and evidence of satisfactory distribution, or the Company has
          filed a preliminary listing application and all required supporting
          documents with respect to the Securities with such stock exchange and
          such counsel has no reason to believe that the Securities will not be
          authorized for listing, subject to official notice of issuance and
          evidence of satisfactory distribution.

          Such counsel may limit its opinion to matters involving the 
     application of the laws of the State of Illinois or the United States or
     the General Corporation Law of the State of Delaware and, in rendering such
     opinion, may rely as to matters of fact, to the extent they deem proper, on
     certificates of responsible officers of the Company and public officials.

          (c) The Representatives shall have received from Mayer, Brown &
     Platt , counsel for the Underwriters, such opinions, dated the Closing
     Date, with respect to the issuance and sale of the Securities, the
     Indenture, any Delayed Delivery Contracts, the Registration Statement, the
     Final Prospectus [2: , the Warrant Agreement] and other related matters as
     the Representatives may reasonably require, and the Company shall have
     furnished to such counsel such documents as they request for the purpose of
     enabling them to pass upon such matters.

          (d) The Company shall have furnished to the Representatives a
     certificate of the Company, signed by the Chairman of the Board, the
     President or any Vice President and by the principal financial or
     accounting officer of the Company, dated the Closing Date, to the effect
     that the signers of such certificate have carefully examined the

     Statement, the Final Prospectus, the Indenture [2: , the Warrant Agreement]
and this Agreement and that:

               (i) the representations and warranties of the Company in this
          Agreement are true and correct in all material respects on and as of
          the Closing Date with the same effect as if made on the Closing Date
          and the Company has complied with all the agreements and satisfied all
          the conditions on its part to be performed or satisfied at or prior to
          the Closing Date;

               (ii) no stop order suspending the effectiveness of the
          Registration Statement has been issued and no proceedings for that
          purpose have been instituted or, to the Company's knowledge,
          threatened; and

               (iii) since the date of the most recent financial statements
          included in the Final Prospectus, there has been no material adverse
          change in the condition (financial or other), earnings, business or
          properties of the Company and its subsidiaries, whether or not arising
          from transactions in the ordinary course of business, except as set
          forth in or contemplated in the Final Prospectus.

          (e) At the Closing Date, Price Waterhouse shall have furnished to the
     Representatives a letter or letters, dated as of the Closing Date, in form
     and substance satisfactory to the Representatives and Price Waterhouse,
     confirming that they are independent accountants with respect to Tribune
     Company within the meaning of the Act and the applicable published rules
     and regulations thereunder, and stating in effect that:

               (i) in their opinion, the consolidated financial statements
          (including financial schedules) of the Company and its subsidiaries
          examined by and reported on by them and included or incorporated by
          reference in the Registration Statement and the Final Prospectus
          comply as to form in all material respects with the applicable
          accounting requirements of the Act and the Exchange Act and the
          related published rules and regulations thereunder with respect to
          registration statements on Form S-3;

               (ii) on the basis of procedures of review in accordance with
          standards established by the American Institute of Certified Public
          Accountants (but not an audit in accordance with generally accepted
          auditing standards) consisting of:

                    (a) reading the minutes of meetings of stockholders and the
               Board of Directors of the Company as set forth in the minute
               books through a specified date not more than five business days
               prior to the date of delivery of such letter;


                                     -12-
<PAGE>
 
                    (b) reading the latest available unaudited interim
               consolidated financial data of the Company and its consolidated
               subsidiaries included or incorporated by reference in the
               Registration Statement or the Final Prospectus and the latest
               unaudited interim financial data made available by the Company
               and its subsidiaries; and

                    (c) making inquiries of certain officials of the Company who
               have responsibilities for financial and accounting matters
               regarding the specific items for which representations are
               requested below;

          nothing has come to their attention as a result of the foregoing
          procedures that caused them to believe that:

                    (1) the unaudited interim consolidated financial data of the
               Company and its consolidated subsidiaries included or
               incorporated by reference in the Registration Statement and the
               Final Prospectus do not comply as to form in all material
               respects with the applicable accounting requirements of the Act
               and the Exchange Act and the related published rules and
               regulations thereunder;

                    (2) any material modifications should be made to said
               unaudited consolidated financial data of the Company and its
               consolidated subsidiaries for it to be in conformity with
               generally accepted accounting principles;

                    (3)(a) with respect to the period subsequent to the date of
               the most recent financial statements (other than any capsule
               information), audited or unaudited, included or incorporated by
               reference in the Registration Statement and the Final Prospectus,
               at the date of the latest available interim financial data and at
               a specified date not more than five business days prior to the
               date of delivery of such letter, except as otherwise disclosed in
               the Final Prospectus or incorporated by reference and except when
               such data is not prepared by or available from the Company, there
               was any change in the common stock or long-term debt of the
               Company and its consolidated subsidiaries or any decreases in
               consolidated total assets, net current assets (working capital)
               or stockholders' investment as compared with amounts shown in the
               latest consolidated balance sheet included or incorporated by
               reference in the Registration Statement or the Final Prospectus
               or (b) for the period from the date of the most recent financial
               statements included or incorporated by reference in the
               Registration Statement or the Final Prospectus to a specified
               date not more than five business days prior to delivery of such
               letter, there were any decreases, as compared with the
               corresponding period in the preceding year,


                                     -13-
<PAGE>
 
               year, in consolidated operating revenues, operating profit,
               income before income taxes or in the total or per-share amounts
               of net income, except in all instances for changes or decreases
               which the Registration Statement and the Final Prospectus
               disclose have occurred or may occur, or as set forth in such
               letter accompanied by an explanation thereof;

                    (4) with regard to the Company and its consolidated
               subsidiaries, the amounts included in any unaudited "capsule"
               information included or incorporated by reference in the
               Registration Statement or the Final Prospectus do not agree with
               the corresponding amounts in the audited or unaudited
               consolidated financial statements from which such amounts were
               derived or were not determined on a basis substantially
               consistent with that of the corresponding amounts in the audited
               financial statements included or incorporated by reference in the
               Registration Statement and the Final Prospectus;

               (iii) they have performed certain other specified procedures as a
          result of which they determined that certain information of an
          accounting, financial or statistical nature (which is limited to
          accounting, financial or statistical information derived from the
          general accounting records of the Company and its subsidiaries and
          subject to the Company's system of internal accounting controls
          relating to the preparation of the financial statements) set forth or
          incorporated by reference in the Registration Statement and the Final
          Prospectus, as amended or supplemented, including Exhibit 12 to the
          Registration Statement and the information included or incorporated in
          Items 1, 6 and 7 of the Company's Annual Report on Form 10-K and in
          "Management's Discussion and Analysis of Financial Condition and
          Results of Operations" included or incorporated by reference in any of
          the Company's Quarterly Reports on Form 10-Q, agrees with the
          accounting records of the Company and its subsidiaries, excluding any
          questions of legal interpretation; and

               (iv) if unaudited pro forma financial statements are included or
          incorporated by reference in the Registration Statement and the Final
          Prospectus, on the basis of a reading of the unaudited pro forma
          financial statements, carrying out certain specified procedures,
          inquiries of certain officials of the Company and the acquired company
          who have responsibility for financial and accounting matters, and
          proving the arithmetic accuracy of the pro forma financial statements,
          nothing came to their attention which caused them to believe that the
          pro forma financial statements were not properly compiled on the pro
          forma bases set forth in the notes thereto.

          References to the Registration Statement and the Final Prospectus in
     the paragraph (e) are to such documents as amended and supplemented at the
     date of the letter.

                                     -14-
<PAGE>
 
          (f) Subsequent to the date as of which information is given in the
     Registration Statement and the Final Prospectus, there shall not have been
     (i) any change or decrease specified in the letter referred to in paragraph
     (e) of this Section 5 or (ii) any change, or any development involving a
     prospective change, in or affecting the business or properties of the
     Company and its subsidiaries the effect of which, in any case referred to
     in clause (i) or (ii) above, is, in the judgment of the Representatives, so
     material and adverse as to make it impractical or inadvisable to proceed
     with the offering or the delivery of the Securities as contemplated by the
     Registration Statement and the Final Prospectus.

          (g) Prior to the Closing Date, the Company shall have furnished to the
     Representatives such further information, certificates and documents as the
     Representatives may reasonably request.

          (h) The Company shall have accepted Delayed Delivery Contracts in any
     case where sales of Contract Securities arranged by the Underwriters have
     been approved by the Company.

          If any of the conditions specified in this Section 5 shall not have
     been fulfilled in all material respects when and as provided in this
     Agreement, or if any of the opinions and certificates mentioned above or
     elsewhere in this Agreement shall not be in all material respects
     reasonably satisfactory in form and substance to the Representatives and
     their counsel, this Agreement and all obligations of the Underwriters
     hereunder may be canceled at, or any time prior to, the Closing Date by the
     Representatives. Notice of such cancellation shall be given to the Company
     in writing or by telephone or telegraph confirmed in writing.

     6. REIMBURSEMENT OF UNDERWRITERS' EXPENSES. If the sale of the [1:
Securities] [2: Units] provided for herein is not consummated because any
condition to the obligations of the Underwriters set forth in Section 5 hereof
is not satisfied or because of any refusal, inability or failure on the part of
the Company to perform any agreement herein or comply with any provision hereof
other than by reason of a default by any of the Underwriters, including a
default under Section 8, the Company will reimburse the Underwriters severally
upon demand for all out-of-pocket expenses (including the reasonable fees and
disbursements of Mayer, Brown & Platt) that shall have been reasonably incurred
by them in connection with the proposed purchase and sale of the [1: Securities]
[2: Units].

     7. INDEMNIFICATION AND CONTRIBUTION. (a) The Company agrees to indemnify
and hold harmless each Underwriter and each person who controls any Underwriter
within the meaning of the Act or the Exchange Act against any and all losses,
claims, damages or liabilities, joint or several, to which they or any of them
may become subject under the Act, the Exchange Act or other Federal or state
statutory law or regulation, at common law or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon any untrue statement or alleged untrue statement of a material
fact contained in the

                                     -15-
<PAGE>
 
registration statement for the registration of the Securities as originally
filed or in any amendment thereof, or in the Basic Prospectus, any Preliminary
Final Prospectus or the Final Prospectus, or in any amendment thereof or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and agrees to reimburse
each such indemnified party for any legal or other expenses reasonably incurred
by them in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that (i) the Company will not be
liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon any such untrue statement or alleged
untrue statement or omission or alleged omission made therein in reliance upon
and in conformity with written information furnished to the Company by or on
behalf of any Underwriter through the Representatives specifically for use in
connection with the preparation thereof, or arises out of or is based upon the
Statement of Eligibility (Form T-1) under the Trust Indenture Act of the
Trustee, and (ii) such indemnity with respect to the Basic Prospectus or any
Preliminary Final Prospectus shall not inure to the benefit of any Underwriter
(or any person controlling such Underwriter) from whom the person asserting any
such loss, claim, damage or liability purchased the Securities which are the
subject thereof if such person did not receive a copy of the Final Prospectus
(or the Final Prospectus as amended or supplemented) excluding documents
incorporated therein by reference at or prior to the confirmation of the sale of
such Securities to such person in any case where such delivery is required by
the Act and the untrue statement or omission of a material fact contained in the
Basic Prospectus or any Preliminary Final Prospectus was corrected in the Final
Prospectus (or the Final Prospectus as amended or supplemented). This indemnity
agreement will be in addition to any liability which the Company may otherwise
have.

             (b) Each Underwriter severally agrees to indemnify and hold
harmless the Company, each of its directors, each of its officers who signs the
Registration Statement, and each person who controls the Company within the
meaning of the Act or the Exchange Act, to the same extent as the foregoing
indemnity from the Company to each Underwriter, but only with reference to
written information relating to such Underwriter furnished to the Company by on
or behalf of such Underwriter through the Representatives specifically for use
in the preparation of the documents referred to in the foregoing indemnity. This
indemnity agreement will be in addition to any liability which any Underwriter
may otherwise have.

             (c) Promptly after receipt by an indemnified party under this
Section 7 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 7, notify the indemnifying party in writing of the
commencement thereof; but the omission so to notify the indemnifying party will
not relieve it from any liability which it may have to any indemnified party
otherwise than under this Section 7. In case any such action is brought against
any indemnified party, and it notifies the indemnifying party of the
commencement thereof, the indemnifying party will be entitled to participate
therein, and to the extent that it may elect by written notice delivered to the
indemnified party promptly after receiving the aforesaid notice from such
indemnified party, to assume the defense thereof, with counsel satisfactory to
such indemnified party; provided,

                                     -16-

<PAGE>
 
however, that if the defendants in any such action include both the indemnified
party and the indemnifying party and the indemnified party shall have reasonably
concluded that there may be legal defenses available to it and/or other
indemnified parties which are different from or additional to those available to
the indemnifying party, the indemnified party or parties shall have the right to
select separate counsel to assert such legal defenses and to otherwise
participate in the defense of such action on behalf of such indemnified party or
parties. Upon receipt of notice from the indemnifying party to such indemnified
party of its election so to assume the defense of such action and approval by
the indemnified party of counsel, the indemnifying party will not be liable to
such indemnified party under this Section 7 for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof unless (i) the indemnified party shall have employed separate counsel in
connection with the assertion of legal defenses in accordance with the proviso
to the next preceding sentence (it being understood, however, that the
indemnifying party shall not be liable for the expenses of more than one
separate counsel (other than local counsel used principally to facilitate local
litigation), approved by the Representatives in the case of paragraph (a) of
this Section 7, representing the indemnified parties under such paragraph (a)
who are parties to such action), (ii) the indemnifying party shall not have
employed counsel satisfactory to the indemnified party to represent the
indemnified party within a reasonable time after notice of commencement of the
action or (iii) the indemnifying party has authorized the employment of counsel
for the indemnified party at the expense of the indemnifying party; and except
that, if clause (i) or (iii) is applicable, such liability shall be only in
respect of the counsel referred to in such clause (i) or (iii). The indemnifying
party 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 (after all rights to appeal have been exhausted) for the plaintiff, the
indemnifying party agrees to indemnify the indemnified party from and against
any loss or liability by reason of such settlement or judgment. Notwithstanding
the foregoing sentence, if at any time an indemnified party shall have requested
an indemnifying party to reimburse the indemnified party for reasonable fees and
expenses of counsel required to be paid by this Section 7(c), the indemnifying
party 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 90 days after receipt by such indemnifying party of the aforesaid request
and (ii) such indemnifying party shall not have reimbursed the indemnified party
in accordance with such aforesaid request prior to the date of such settlement.
No indemnifying party shall, without the prior written consent of the
indemnified party (which consent shall not be unreasonably withheld), effect any
settlement of any pending or threatened proceeding in respect of which any
indemnified party is a party unless such settlement includes an unconditional
release of such indemnified party from all liability on claims that are the
subject matter of such proceeding.

          (d) In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in paragraph (a) of this
Section 7 is due in accordance with its terms but is for any reason held by a
court to be unavailable from the Company on grounds of policy or otherwise, the
Company and the Underwriters shall contribute to the aggregate losses, claims,
damages and liabilities (including legal or other expenses reasonably incurred
in connection with investigating or defending same) to which the Company and one
or more of the Underwriters may be subject in such proportion so that the
Underwriters are responsible for that portion represented by the percentage that
the underwriting discount bears to the sum of such discount and the purchase
price of the [1:  Securities] [2:  Units] specified in Schedule I hereto and the
Company is responsible for the balance; provided, however, that (y) in no case
shall any Underwriter (except as may be provided in the agreement among
underwriters relating to the offering of the [1:  Securities] [2:  Units]) be
responsible for any amount in excess of the underwriting discount applicable to
the [1:  Securities] [2:  Units]) purchased by such Underwriter hereunder and
(z) no person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Act) shall be entitled to contribution from any person who
was not guilty of such fraudulent misrepresentation.  For purposes of this
Section 7, each person who controls an Underwriter within the meaning of the Act
shall have the same rights to contribution 


                                     -17-
<PAGE>
 
as such Underwriter, and each person who controls the Company within the meaning
of the Act or the Exchange Act, each officer of the Company who shall have
signed the Registration Statement and each director of the Company shall have
the same rights to contributions as the Company, subject in each case to clause
(y) of this paragraph (d). Any party entitled to contribution will, promptly
after receipt of notice of commencement of any action, suit or proceeding
against such party in respect of which a claim for contribution may be made
against another party or parties under this paragraph (d), notify such party or
parties from whom contribution may be sought, but the omission to so notify such
party or parties shall not relieve the party or parties from whom contribution
may be sought from any other obligation it or they may have hereunder or
otherwise than under this paragraph (d).

     8.   DEFAULT BY AN UNDERWRITER.  If any one or more Underwriters shall fail
to purchase and pay for any of the [1:  Securities] [2:  Units] agreed to be
purchased by such Underwriter or Underwriters hereunder and such failure to
purchase shall constitute a default in the performance of its or their
obligations under this Agreement, the remaining Underwriters shall be obligated
severally to take up and pay for (in the respective proportions which the [1:
principal amount of Securities] [2:  number of Units] set forth opposite their
names in Schedule II hereto bears to the aggregate [1:  principal amount of
Securities] [2:  number of Units] set forth opposite the names of all the
remaining Underwriters) the  [1:  Securities] [2:  Units] which the defaulting
Underwriter or Underwriters agreed but failed to purchase; provided, however,
that in the event that the aggregate [1:  principal amount of Securities] [2:
number of Units] which the defaulting Underwriter or Underwriters agreed but
failed to purchase shall exceed 10% of the aggregate [1:  principal amount of
Securities] [2:  number of Units] set forth in Schedule II hereto, the remaining
Underwriters shall have the right to purchase all, but shall not be under any
obligation to purchase any, of the [1:  Securities] [2:  Units], and if such
nondefaulting Underwriters do not purchase all the [1:  Securities] [2:  Units]
this Agreement will terminate without liability to any nondefaulting Underwriter
or the Company.  In the event of a default by any Underwriter as set forth in
this Section 8, the Closing Date shall be postponed for such period, not
exceeding seven days, as the Representatives shall determine in order that the
required changes in the Registration Statement and the Final Prospectus or in
any other documents or arrangements may be effected.  Nothing contained in this
Agreement shall relieve any defaulting Underwriter of its liability, if any, to
the Company and any nondefaulting Underwriter for damages occasioned by its
default hereunder.

     9.   TERMINATION.  This Agreement shall be subject to termination in the
absolute discretion of the Representatives, by notice given to the Company prior
to delivery of and payment for the [1:  Securities] [2:  Units], if prior to
such time (i) trading in the Company's Common Stock shall have been suspended by
the Commission or the New York Stock Exchange or trading in securities generally
on the New York Stock Exchange shall have been suspended or limited or minimum
prices shall have been established on such Exchange, (ii) a banking moratorium
shall have been declared either by Federal or New York State authorities or
(iii) there shall have occurred any outbreak or material escalation of
hostilities or other calamity or crisis the effect of which on the financial
markets of the United States is such as to make it, in the judgment of the
Representatives, impracticable to market the [1:  Securities] [2:  Units].

     10. REPRESENTATIONS AND INDEMNITIES TO SURVIVE. The respective agreements,
representations, warranties, indemnities and other statements of the Company or
its officers and of the Underwriters set forth in or made pursuant to this
Agreement will remain in full force and effect, regardless of any investigation
made by or on behalf of any Underwriter or the Company or any of the officers,
directors or controlling persons referred to in Section 7 hereof, and will
survive delivery of and payment for the Securities. The provisions of Section 6
and 7 hereof shall survive delivery of and payment for the Securities. The
provisions of Sections 6 and 7 hereof shall survive the termination or
cancellation of this Agreement.

     11. NOTICES. All communications hereunder will be in writing and effective
only on receipt, and, if sent to the Representatives, will be mailed, delivered
or telegraphed and confirmed to them, at the address specified in Schedule I
hereto; or, if sent to the Company, will be mailed, delivered or telegraphed and
confirmed to it at Tribune Company, 435 North Michigan Avenue, Chicago, Illinois
60611, attention of David J. Granat, Vice President and Treasurer (with a copy
to the General Counsel of Tribune Company).

     12. SUCCESSORS. This Agreement will inure to the benefit of and be binding
upon the parties hereto and their respective successors and the officers and
directors and controlling persons referred to in Section 7 hereof, and no other
person will have any right or obligation hereunder.

     13. APPLICABLE LAW. This Agreement will be governed by and construed in
accordance with the laws of the State of New York.

     14. COUNTERPARTS. This Agreement and any amendments hereto may be executed
in any number of counterparts, each of which shall be deemed to be an original
but all of which together shall constitute but one agreement.

Dear Sirs:

     Tribune Company, a Delaware corporation (the "Company"), confirms its
agreement with each of you with respect to the issue and sale by the Company of
up to the aggregate principal amount set forth in Schedule I hereto of its
Medium-Term Notes, Series D Due Nine Months or More from Date of Issue (the
"Notes").  The Notes will be issued under an indenture dated as of March 1, 1992
between the Company and First Trust of Illinois, National Association, as
successor trustee (the "Trustee"), as supplemented to the date hereof and/or as
modified from time to time by resolutions of the Board of Directors as provided
in Section 3.01 thereof (the "Indenture").  The Notes will, unless otherwise
specified, be issued in minimum denominations of $1,000 and in denominations
exceeding such amount by integral multiples of $1,000, will be issued only in
fully registered form and will have the maturities, annual interest rates,
redemption provisions and other terms set forth in a supplement to the
Prospectus (as hereinafter defined) referred to below.  The Notes will be
issued, and the terms thereof established, in accordance with the Indenture and,
in the case of Notes sold pursuant to Section 2(a) hereof, the Medium-Term Notes
Administrative Procedures attached hereto as Exhibit A (the "Procedures").  The
Procedures may only be amended by written agreement of the Company and the
Agents after notice to, and with the approval of, the Trustee.  For the purposes
of this Agreement, the term "Agent" shall refer to any of you acting solely in
the capacity as agent for

                                       1
<PAGE>
 
the Company pursuant to Section 2(a) and not as principal (collectively, the
"Agents"), the term the "Purchaser" shall refer to any of you acting solely as
principal pursuant to Section 2(b) and not as agent (collectively, the
"Purchasers"), and the term "you" shall refer to you collectively whether at any
time any of you is acting in both such capacities or in either such capacity.
Nothing in this agreement shall preclude an Agent from purchasing Notes as a
principal hereunder while acting as an Agent.

  1.  Representations and Warranties  The Company represents and warrants to,
and agrees with, the Agents that:

        (a)  The Company meets the requirements for use of Form S-3 under the
Securities Act of 1933, as amended (the "Act"), and has filed with the
Securities and Exchange Commission (the "Commission") a registration statement
on such Form (the file number of which is set forth on Schedule I hereto), which
has become effective, for the registration under the Act of the aggregate
principal amount set forth in Schedule I hereto of debt securities including the
Notes (the "Securities").  Such registration statement, as amended at the date
of this Agreement, meets the requirements set forth in Rule 415(a)(1)(x) under
the Act and complies in all other material respects with said Rule.  In
connection with the sale of Notes the Company has filed or transmitted for
filing with the Commission, pursuant to Rule 424 under the Act, a supplement to
the form of prospectus included in such registration statement relating to the
Notes and the plan of distribution thereof (the "Prospectus Supplement") and has
previously advised the Agents of all further information (financial and other)
with respect to the Company to be set forth therein.  In connection with the
sale of Notes, the Company will file with the Commission pursuant to Rule 424
under the Act further supplements to that supplement specifying the maturity
dates, interest rates and other similar terms of any Notes sold pursuant
thereto.  Such registration statement, including the exhibits thereto, as
amended to the date of this Agreement, is hereinafter called the "Registration
Statement"; such prospectus, in the form included in the Registration Statement,
as supplemented from time to time (including, without limitation, as
supplemented by the Prospectus Supplement) is hereinafter called the
"Prospectus".  Any reference herein to the Registration Statement 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 which were filed under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), on or before
the date of this Agreement or the date of the Prospectus, as the case may be;
and any reference herein to the terms "amend," "amendment" or "supplement" with
respect to the Registration Statement or the Prospectus shall be deemed to refer
to and include any amendment to the Registration Statement filed with the
Commission pursuant to the Act after the date of this Agreement, any supplement
to the Prospectus filed with this Commission pursuant to Rule 424 under the Act
after the date of this Agreement and the filing of any document under the
Exchange Act after the date of this Agreement or the date of the Prospectus, as
the case may be, deemed to be incorporated therein by reference.

        (b) (i)  As of the date hereof, (ii) at the date of any acceptance by
the Company of an offer to purchase Notes, (iii) when any amendment to the
Registration Statement becomes effective (including the filing of any document
incorporated by reference in the Registration Statement), (iv) as of the date of
any Terms Agreement (as defined by Section 2(b)), (v) when any supplement to

                                       2
<PAGE>
 
the Prospectus is filed with the Commission and (vi) at the date of delivery by
the Company of any Notes sold hereunder (a "Closing Date"):  (x) the
Registration Statement, as amended as of any such time, and the Prospectus, as
supplemented as of any such time, and the Indenture will comply in all material
respects with the applicable requirements of the Act, the Trust Indenture Act of
1939, as amended (the "Trust Indenture Act"), and the Exchange Act and the
respective rules and regulations thereunder, (y) the Registration Statement, as
amended as of any such time, did not or will not contain any untrue statement of
a material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein not misleading; and (z) the
Prospectus, as supplemented as of any such time, will 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 light of the circumstances under which they
were made, not misleading; provided, however, that the Company makes no
representations or warranties as to (x) that part of the Registration Statement
which shall constitute the Statement of Eligibility (Form T-1) under the Trust
Indenture Act of the Trustee or (y) the information contained in or omitted from
the Registration Statement or Prospectus in reliance upon and in conformity with
information furnished in writing to the Company by or on behalf of any of you
specifically for use in the Registration Statement and the Prospectus.

        (c)  As of the date hereof, at the date of any acceptance by the Company
of an offer to purchase Notes, when any amendment to the Registration Statement
becomes effective (including the filing of any document incorporated by
reference in the Registration Statement), as of the date of any Terms Agreement,
when any supplement to the Prospectus is filed with the Commission and at a
Closing Date:

              (i)  each of the Company and Chicago Tribune Company, Sentinel 
        Communications Company, Sun-Sentinel Company and Tribune Broadcasting
        Company (individually, a "Designated Subsidiary" and collectively, the
        "Designated Subsidiaries") has been duly incorporated and is validly
        existing as a corporation in good standing under the laws of the
        jurisdiction in which it is chartered or organized, with full corporate
        power and authority to own its properties and conduct its business as
        described in the Prospectus, and is duly qualified or licensed to do
        business as a foreign corporation and is in good standing under the laws
        of each jurisdiction where the character of the properties owned or
        leased or the nature of the activities conducted by such corporations,
        respectively, makes such qualifications or licensing necessary, and
        where the failure to be so qualified or licensed might materially
        adversely affect the financial condition, assets, operations or
        prospects of the Company and its subsidiaries considered as one
        enterprise;

              (ii) all the outstanding shares of capital stock of each
        Designated Subsidiary have been duly and validly authorized and issued
        and are fully paid and nonassessable, and, except as otherwise set forth
        in the Prospectus, all outstanding shares of capital stock of the
        Designated Subsidiaries are owned by the Company either directly or
        through wholly owned subsidiaries free and clear of any perfected
        security interest and any other security interests, claims, liens or
        encumbrances;

                                       3

<PAGE>
 
              (iii) the Indenture has been duly authorized, executed and
        delivered and constitutes a legal, valid and binding instrument
        enforceable against the Company in accordance with its terms (subject,
        as to enforcement of remedies, to applicable bankruptcy, reorganization,
        insolvency, moratorium or other laws affecting creditors' rights
        generally from time to time in effect and to general principles of
        equity (regardless of whether enforceability is considered in a
        proceeding in equity or at law)); the Indenture has been duly qualified
        under the Trust Indenture Act; and the Notes have been duly authorized
        and, when executed and authenticated in accordance with the provisions
        of the Indenture and delivered to and paid for by the purchasers
        thereof, will constitute legal, valid and binding obligations of the
        Company, except as enforcement thereof may be limited by bankruptcy,
        insolvency, reorganization, moratorium or other laws of general
        applicability relating to or affecting the enforcement of creditor's
        rights or by the effect of general principles of equity (regardless of
        whether enforceability is considered in a proceeding in equity or at
        law) and will be entitled to the benefits of the Indenture;

              (iv) the financial statements of the Company and its consolidated
        subsidiaries included or incorporated by reference in the Prospectus
        present fairly the financial position of the Company and such
        consolidated subsidiaries as at the dates indicated and the results of
        their operations for the periods specified; except as stated therein,
        said financial statements have been prepared in conformity with
        generally accepted accounting principles applied on a consistent basis;

              (v) to the best knowledge of the Company, there is no pending or
        threatened action, suit or proceeding before any court or governmental
        agency, authority or body or any arbitrator involving the Company or any
        of the Designated Subsidiaries of a character required to be disclosed
        in the Registration Statement which is not adequately disclosed in the
        Prospectus, and there is no franchise, contract or other document of a
        character required to be described in the Registration Statement or
        Prospectus, or to be filed as an exhibit, which is not described or
        filed as required;

              (vi) this Agreement has been duly authorized, executed and
        delivered by the Company;

              (vii) no consent, approval, authorization or order of any court or
        governmental agency or body, domestic or foreign, is required for the
        consummation of the transactions contemplated herein except such as have
        been obtained under the Act and such as may be obtained under the blue
        sky laws of any jurisdiction in connection with the sale of the Notes as
        contemplated by this Agreement and such other approvals as have been
        obtained; and

              (viii) none of the execution of the Indenture, the issuance and
        sale of the Notes, the consummation of any other of the transactions
        herein contemplated or the fulfillment of the terms hereof will conflict
        with, result in a breach of, or constitute a default under the charter
        or by-laws of the Company or the terms of any indenture or other
        agreement or instrument

                                       4

        to which the Company or any of the Designated Subsidiaries is a party or
        bound, or any order, decree, rule or regulation known to the Company to
        be applicable to the Company or any of its subsidiaries of any court,
        regulatory body, administrative agency, governmental body or arbitrator,
        domestic or foreign, having jurisdiction over the Company or any of its
        subsidiaries.

        (d) The Company confirms as of the date hereof, and each acceptance by
the Company of an offer to purchase Notes will be deemed to be an affirmation,
that the Company is in compliance with all provisions of Section 1 of Laws of
Florida, Chapter 92-198, An Act Relating to Disclosure of Doing Business with
Cuba, and the Company further agrees that if it commences engaging in business
with the government of Cuba or with any person or affiliate located in Cuba
after the date the Registration Statement becomes or has become effective with
the Commission or with the Florida Department of Banking and Finance (the
"Department"), whichever date is later, or if the information reported in the
Prospectus, if any, concerning the Company's business with Cuba or with any
person or affiliate located in Cuba changes in any material way, the Company
will provide the Department notice of such business or change, as appropriate,
in a form acceptable to the Department.

        2.  Appointment of Agent(s); Solicitation by the Agents of Offers to
Purchase; Sales of Notes to a Purchaser.  (a)  Subject to the terms and
conditions set forth herein and subject to the reservation by the Company of the
right to sell Notes directly to purchasers on its own behalf or through other
agents, dealers or underwriters on terms substantially identical to the terms
contained herein, including the commission schedule set forth in Schedule I
hereto, except in the case of sales pursuant to a Terms Agreement (as defined
herein) the Company hereby authorizes each of the Agents to act as its agent to
solicit offers for the purchase of all or part of the Notes from the Company.

        On the basis of the representations and warranties, and subject to the
terms and conditions set forth herein, each of the Agents agrees, as agent of
the Company, to use its reasonable best efforts to solicit offers to purchase
the Notes from the Company upon the terms and conditions set forth in the
Prospectus as amended or supplemented and in the Procedures.

        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 offers to purchase the Notes.  Upon receipt of instructions from
the Company, the Agents will forthwith suspend solicitation of offers to
purchase Notes from the Company until such time as the Company has advised them
that such solicitation may be resumed.  If the Company has instructed the Agents
to suspend for any period of time the solicitation of offers to purchase the
Notes and thereafter requests the Agents to resume the solicitation of offers to
purchase the Notes, the Agents shall not be required to resume such solicitation
(i) earlier than the date five business days (or such fewer business days as
shall be acceptable to each such Agent) after such request and (ii) unless each
Agent shall have received prior to such resumption the documents referred to in
Sections 4(i), (j) and (k) which the Agents had been entitled to receive
(assuming that any required notices had been timely made) but which such Agents
shall not have theretofore received.

                                       5

<PAGE>
 
        The Company agrees to pay each Agent a commission on the Closing Date
with respect to each sale of Notes by the Company as a result of a solicitation
made by such Agent, in an amount equal to that percentage specified on Schedule
I hereto of the aggregate principal amount of the Notes so sold by the Company
and such commission shall be payable as specified in the Procedures.

        Subject to the provisions of this Section and to the Procedures, offers
for the purchase of Notes may be solicited by an Agent as agent for the Company
at such time and in such amounts as such Agent deems advisable. The Company may
from time to time offer Notes for sale otherwise than through an Agent.

        (b) Subject to the terms and conditions stated herein, whenever the
Company and one of you determines that the Company shall sell Notes directly to
you as Purchaser, each such sale of Notes shall be made in accordance with the
terms of this Agreement and a supplemental agreement relating thereto between
the Company and the Purchaser. Each such supplemental agreement (which (i) may
be an oral agreement between the Purchaser and the Company or (ii) may take the
form of an exchange of any standard form of written telecommunication between a
Purchaser and the Company) is herein referred to as a "Terms Agreement." Each
such Terms Agreement, if in writing, shall be substantially in the form of
Exhibit B and, if oral, shall be confirmed in writing as soon as practicable
after the agreement between the Purchaser and the Company, such confirmation to
be substantially in the form of Exhibit B. The Purchaser's commitment to
purchase Notes pursuant to any Terms Agreement 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 herein set forth.
Each Terms Agreement shall describe the Notes to be purchased by the Purchaser
pursuant thereto, specify the principal amount of such Notes, the price to be
paid to the Company for such Notes, the rate at which interest will be paid on
the Notes, the Closing Date for such Notes, the place of delivery of the Notes
and payment therefor, the method of payment and any modification of the
requirements for the delivery of the opinions of counsel, the certificates from
the Company or its officers, and the letter from the Company's independent
public accountants, pursuant to Section 6(b). Such Terms Agreement shall also
specify the period of time referred to in Section 4(1).

        Delivery of the certificates for Notes sold to the Purchaser pursuant to
any Terms Agreement shall be made as agreed to between the Company and the
Purchaser as set forth in the respective Terms Agreement, not later than the
Closing Date set forth in such Terms Agreement, against payment of funds to the
Company in the net amount due the Company for such Notes by the method and in
the form set forth in the respective Terms Agreement.

        Unless otherwise agreed to between the Company and the Purchaser in a
Terms Agreement, any Note sold to a Purchaser (i) shall be purchased by such
Purchaser at a price equal to 100% of the principal amount thereof less a
percentage equal to the commission applicable to an agency sale of a Note of
identical maturity and (ii) may be resold by such Purchaser at varying prices
from time to time or, if set forth in the applicable Terms Agreement and Pricing
Supplement, at a fixed public offering price. In connection with any resale of
Notes purchased, a Purchaser may use a selling or

                                       6

<PAGE>
 
dealer group and may reallow to any broker or dealer any portion of the discount
or commission payable pursuant hereto.

        3. Offering and Sale of Notes. Each Agent and the Company agree to
perform the respective duties and obligations specifically provided to be
performed by them in the Procedures.

        4.  Agreements.  The Company agrees with you that:
            ----------                                    

        (a) Prior to the termination of the offering of the Notes, the Company
will not file any amendment of the Registration Statement or supplement to the
Prospectus (except for a supplement relating to an offering of securities other
than the Notes) unless the Company has previously furnished to each of you a
copy for your review prior to filing. Subject to the foregoing sentence, the
Company will cause each supplement to the Prospectus to be filed with the
Commission as required pursuant to Rule 424. The Company will promptly advise
each of you (i) when each supplement to the Prospectus shall have been filed
with the Commission pursuant to Rule 424, (ii) when any amendment of the
Registration Statement shall have become effective, (iii) of any request by the
Commission for any amendment of the Registration Statement or amendment of or
supplement to the Prospectus or for any additional information, (iv) of the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement or the institution or threatening of any proceeding for
that purpose and (v) of the receipt by the Company of any notification with
respect to the suspension of the qualification of the Notes for sale in any
jurisdiction or the initiation or threatening of any proceeding for such
purpose. The Company will use its best efforts to prevent the issuance of any
such stop order or notification and, if issued, to obtain as soon as possible
the withdrawal thereof.

        (b) If, at any time when a prospectus relating to the Notes is required
to be delivered under the Act, any event occurs as a result of which the
Registration Statement, as then amended, or the Prospectus, as then
supplemented, would include any untrue statement of a material fact or omit to
state any material fact necessary to make the statements therein in the light of
the circumstances under which they were made not misleading, or if it shall be
necessary to amend the Registration Statement or to supplement the Prospectus to
comply with the Act or the Exchange Act or the respective rules thereunder, the
Company promptly will (i) notify each of you to suspend solicitation of offers
to purchase Notes (and, if so notified by the Company, each of you shall
forthwith suspend such solicitation and cease using the Prospectus as then
amended or supplemented), (ii) prepare and file with the Commission, subject to
the first sentence of paragraph (a) of this Section 4, an amendment or
supplement which will correct such statement or omission or an amendment or
supplement which will effect such compliance and (iii) supply any such amended
or supplemented Prospectus to each of you in such quantities as you may
reasonably request. If such amendment or supplement, and any documents,
certificates and opinions furnished to each of you pursuant to paragraph (f) of
this Section 4 in connection with the preparation or filing of such amendment or
supplement, are satisfactory in all respects to you, you will, upon the filing
of such amendment or supplement with the Commission and upon the effectiveness
of an amendment to the Registration Statement if such an amendment is required,
resume your obligation to solicit offers to purchase Notes hereunder.

                                       7

<PAGE>
 
        (c) As soon as practicable, the Company will make generally available to
its security holders and to each of you an earnings statement or statements
(which need not be audited) of the Company and its subsidiaries which will
satisfy the provisions of Section 11(a) of the Act and Rule 158 under the Act.

        (d) The Company will furnish to each of you and your counsel, without
charge, one signed and/or conformed copy of the Registration Statement
(including exhibits thereto) and each amendment thereto which shall become
effective and, so long as delivery of a prospectus may be required by the Act,
the Company will furnish to each of you as many copies of any preliminary
Prospectus and the Prospectus and any amendments thereof and supplements thereto
as you may reasonably request.

        (e) The Company will (i) arrange for the qualification of the Notes for
sale under the laws of such jurisdictions as you and the Company may mutually
agree, which agreement will not be unreasonably withheld, (ii) maintain such
qualifications in effect so long as required for the distribution of the Notes,
and (iii) arrange for the determination of the legality of the Notes for
purchase by institutional investors; provided, however, that the Company shall
not be required to effect or maintain any such qualification in any jurisdiction
that would result in it having to execute or file a general consent to service
of process under the laws of such jurisdiction or to qualify to do business as a
foreign corporation in such jurisdiction.

        (f)  The Company shall furnish to each of you such documents,
certificates of officers of the Company and opinions of counsel for the Company
relating to the business, operations and affairs of the Company, the
Registration Statement, any preliminary Prospectus, the Prospectus, and any
amendments thereof or supplements thereto, the Indenture, the Notes, this
Agreement, any Terms Agreement, and the performance by the Company and each of
you of your respective obligations hereunder and thereunder as the Company and
each of you may from time to time and at any time prior to the termination of

provision hereof), (i) pay all expenses incident to the performance of its
obligations under this Agreement, including the fees and disbursements of its
accountants and counsel, the cost of printing and delivery of the Registration

and supplements thereto, the Indenture, this Agreement and all other documents
relating to the offering, the cost of preparing, printing, packaging and

        (h) Each acceptance by the Company of an offer to purchase Notes will be
deemed to be (i) a representation and warranty to you that neither the
Registration Statement nor the Prospectus, as then amended or supplemented,
fails to reflect any facts or events which, individually or in the aggregate,
represent a material change in the information set forth in the Registration
Statement or the Prospectus, as then amended or supplemented and (ii) a
reconfirmation of the representations and warranties of the Company in Section
1(b).

        (i) Each time that the Registration Statement or the Prospectus is
amended (including by the filing of any document incorporated by reference in
the Registration Statement other than a current report on form 8-K which is
reasonably deemed immaterial by all of the Agents) or supplemented (other than
by an amendment or supplement relating solely to any offering of securities
other than the Notes or providing solely for the specification of or a change in
the maturity dates, the interest rates, the issuance prices or other similar
terms offered on any Notes), the Company will deliver or cause to be delivered
promptly to each of you a certificate of the Company signed by the President or
any Vice President and the principal financial or accounting officer of the
Company, dated the date of the effectiveness of such amendment or the date of
filing of such supplement, in form reasonably satisfactory to you, to the effect
that the statements contained in the certificate that was last furnished to you
pursuant to either Section 5(d) or this Section 4(i) are true and correct at the
time of the effectiveness of such amendment or the filing of such supplement as
though made at and as of such time (except that (i) the last day of the fiscal
quarter for which financial statements of the Company were last filed with the
Commission shall be substituted for the corresponding date in such certificate
and (ii) such statements shall be deemed to relate to the Registration Statement
and the Prospectus as amended and supplemented to the time of the effectiveness
of such amendment or the filing of such supplement) or, in lieu of such
certificate, a certificate of the same tenor as the certificate referred to in
Section 5(d) but modified to relate to the last day of the fiscal quarter for
which financial statements of the Company were last filed with the Commission
and to the Registration Statement and the Prospectus as amended and supplemented
to the time of the effectiveness of such amendment or the filing of such
supplement.
   
        (j) Each time that the Registration Statement or the Prospectus is
amended (including by the filing of any document incorporated by reference in
the Registration Statement) or supplemented (other than by an amendment or
supplement (i) relating solely to any offering of securities other than the
Notes, (ii) providing solely for the specification of or a change in the
maturity dates, the interest rates, the issuance prices or other similar terms
offered on any Notes or (iii) setting forth or incorporating by reference
financial statements or other information as of and for a fiscal quarter,
unless, in the case of clause (iii) above, in the reasonable judgment of any of
you, confirmed to the Company in writing, such financial statements or other
information are of such a nature that an opinion of counsel should be
furnished), the Company shall furnish or cause to be furnished promptly to each
of you a written opinion of counsel of the Company satisfactory to each of you,
dated the date of the effectiveness of such amendment or the date of filing of
such supplement, in form satisfactory to each of you, of the same tenor as the
opinion referred to in Section 5(b) but modified to relate to the Registration
Statement and the Prospectus as amended and supplemented to the time of the
effectiveness of such amendment or the filing of such supplement or, in lieu of
such opinion,

                                       9

<PAGE>
 
counsel last furnishing such an opinion to you may furnish each of you with a
letter to the effect that you may rely on such last opinion to the same extent
as though it were dated the date of such letter authorizing reliance (except
that statements in such last opinion will be deemed to relate to the
Registration Statement and the Prospectus as amended and supplemented to the
time of the effectiveness of such amendment or the filing of such supplement).

        (k) Each time that the Registration Statement or the Prospectus is
amended or supplemented to set forth amended or supplemental financial
information or such amended or supplemental information is incorporated by
reference in the Registration Statement or the Prospectus, the Company, upon the
written request of any Agent (except that no such request shall be required with
respect to audited financial statements and related financial information
included or incorporated by reference in the Company's Annual Reports on Form 
10-K), shall cause Price Waterhouse LLP ("Price Waterhouse"), its independent
public accountants, promptly to furnish to each of you a letter, dated the date
of the effectiveness of such amendment or the date of filing of such supplement,
in form satisfactory to each of you, of the same tenor as the letter referred to
in Section 5(e) with such changes as may be necessary to reflect the amended and
supplemental financial information included or incorporated by reference in the
Registration Statement and the Prospectus, as amended or supplemented to the
date of such letter, provided that if the Registration Statement or the
Prospectus is amended or supplemented solely to include or incorporate by
reference financial information as of and for a fiscal quarter, Price Waterhouse
may limit the scope of such letter, which shall be satisfactory in form to each
of you, to the unaudited financial statements included in such amendment or
supplement, unless any other information included or incorporated by reference
therein of an accounting, financial or statistical nature is of such a nature
that, in your reasonable judgment, such letter should cover such other
information.

        (l) During the period, if any, specified in any Terms Agreement, the
Company shall not, without the prior consent of the Purchaser(s) thereunder,
issue or announce the proposed issuance of any of its debt securities, including
Notes, with terms substantially similar to the Notes being purchased pursuant to
such Terms Agreement.

        (m) The Company, during the period when a prospectus relating to the
Notes is required to be delivered under the Act, will file promptly all
documents required to be filed with the Commission pursuant to Section 13(a),
13(c), 14 or 15(d) of the Exchange Act and will furnish to each of you copies of
such documents. In addition, if the Company makes any announcement to the
general public concerning earnings or concerning any other event which is
required to be described, or which the Company proposes to describe, in a
document filed pursuant to the Exchange Act, the Company will furnish to each of
you upon request the information contained in such announcement as soon as
practicable after such announcement. The Company also will furnish to each of
you upon request copies of all other press releases or announcements to the
general public. The Company will immediately notify each of you of any
downgrading in the rating of the Notes or any other debt securities of the
Company, by any "nationally recognized statistical rating organization" (as
defined for purposes of Rule 426(g) under the Act), as soon as the Company
learns of any such downgrading.

        (a)  If filing of the Prospectus, or any supplement thereto, is required
pursuant to Rule 424(b), the Prospectus, and any such supplement, shall have

purpose shall have been instituted or threatened.

        (b)  The Company shall have furnished to each Agent the opinion of
Sidley & Austin, counsel for the Company, dated the date hereof, to the effect
that:

              (i) each of the Company and the Designated Subsidiaries has been
        duly incorporated and is validly existing as a corporation in good
        standing under the laws of the jurisdiction in which it is chartered or
        organized, with full corporate power and authority to own its properties
        and conduct its business as described in the Prospectus;

              (ii) all the outstanding shares of capital stock of each
        Designated Subsidiary have been duly and validly authorized and issued
        and are fully paid and nonassessable, and, to the knowledge of such
        counsel, except as otherwise set forth in the Prospectus, all
        outstanding shares of capital stock of the Designated Subsidiaries are
        owned by the Company either directly or through wholly owned
        subsidiaries and are free and clear of any security interests, claims,
        liens or encumbrances;

              (iii) the Notes and the Indenture conform in all material respects
        to the description thereof contained in the Prospectus; the holders of
        outstanding shares of capital stock of the Company are not entitled to
        rights to subscribe for the Notes;

              (iv) the Indenture has been duly authorized, executed and
        delivered by the Company and constitutes a legal, valid and binding
        instrument enforceable against the Company in accordance with its terms
        except as enforcement thereof may be limited by bankruptcy, insolvency,
        reorganization, moratorium or other laws of general applicability
        relating to or affecting the enforcement of creditor's rights or by the
        effect of general principles of equity (regardless of whether
        enforceability is considered in a proceeding in equity or at law); the
        Indenture has been duly qualified under the Trust Indenture Act; and the
        Notes have been duly authorized and when executed and authenticated in
        accordance with the provisions of

                                      11

<PAGE>
 
        the Indenture and the procedures adopted by the Board of Directors of
        the Company and the Special Committee thereof and delivered to and paid
        for by the purchasers thereof in the manner provided in this Agreement,
        the Prospectus and any applicable Terms Agreement, will constitute
        legal, valid and binding obligations of the Company except as
        enforcement thereof may be limited by bankruptcy, insolvency,
        reorganization, moratorium or other laws of general applicability
        relating to or affecting the enforcement of creditor's rights or by the
        effect of general principles of equity (regardless of whether
        enforceability is considered in a proceeding in equity or at law) and
        will be entitled to the benefits of the Indenture;

              (v) to the knowledge of such counsel, there is no pending or
        threatened action, suit or proceeding before any court or governmental
        agency, authority or body or any arbitrator involving the Company or any
        of its Designated Subsidiaries of a character required to be disclosed
        in the Registration Statement which is not adequately disclosed in the
        Prospectus, and there is no franchise, contract or other document of a
        character required to be described in the Registration Statement or
        Prospectus, or to be filed as an exhibit to the Registration Statement,
        which is not described or filed as required; and the statements included
        or incorporated in the Prospectus with respect to any such action, suit,
        proceeding, franchise, contract or other document fairly summarize the
        matters required to be disclosed or described;

              (vi) the Registration Statement and any amendments thereto have
        become effective under the Act; to the best knowledge of such counsel,
        no stop order suspending the effectiveness of the Registration Statement
        has been issued, no proceedings for that purpose have been instituted or
        threatened; the Registration Statement, the Prospectus and each
        amendment thereof or supplement thereto as of their respective effective
        or issue dates (other than the financial statements, financial data,
        statistical data and supporting schedules included or incorporated by
        reference therein, as to which such counsel need express no opinion)
        complied as to form in all material respects with the applicable
        requirements of the Act and the Exchange Act and the respective rules
        thereunder; and, although such counsel has not independently verified,
        is not passing upon and assumes no responsibility for the accuracy,
        completeness or fairness of statements contained in the Registration
        Statement, the Prospectus or any amendment thereof or supplement
        thereto, except as noted above, nor has such counsel verified the
        computation or compilation of financial statements and other financial
        data, nothing has come to such counsel's attention which causes such
        counsel to believe that the Registration Statement or any amendment
        thereof (other than the financial statements, financial data,
        statistical data and supporting schedules, as to which such counsel need
        express no belief) at the time it became effective and at the date of
        this Agreement, contained any untrue statement of a material fact or
        omitted to state any material fact required to be stated therein or
        necessary to make the statements therein not misleading or that the
        Prospectus (other than the financial statements, financial data,
        statistical data and supporting schedules, as to which such counsel need
        express no belief), at the date of such opinion, includes any untrue
        statement of a material fact or omits to state a material fact necessary
        to

                                      12

<PAGE>
 
        make the statements therein, in the light of the circumstances under
        which they were made, not misleading;

              (vii) this Agreement has been duly authorized, executed and
        delivered by the Company;

              (viii) no consent, approval, authorization or order of any court
        or governmental agency or body, domestic or foreign, is required for the
        consummation of the transactions contemplated herein except such as have
        been obtained under the Act and the Trust Indenture Act and such as may
        be required under the blue sky laws of any jurisdiction in connection
        with the sale or offer for sale of the Notes as contemplated by this
        Agreement and such other approvals (specified in such opinion) as have
        been obtained;

              (ix) none of the execution of the Indenture, the issuance and sale
        of the Notes, the consummation of any other of the transactions herein
        contemplated or the fulfillment of the terms hereof will result in a
        breach of, or constitute a default under, the charter or by-laws of the
        Company or the terms of any indenture or other material agreement or
        instrument known to such counsel and to which the Company or any of its
        Designated Subsidiaries is a party or bound, or any order, decree, rule
        or regulation known to such counsel to be applicable to the Company or
        any of its Designated Subsidiaries of any court, regulatory body,
        administrative agency, governmental body or arbitrator, domestic or
        foreign, having jurisdiction over the Company or any of its Designated
        Subsidiaries; and

              (x) no holders of outstanding securities of the Company have
        rights to the registration of such securities under the Registration
        Statement.

              Such counsel may limit its opinion to matters involving the
        application of the laws of the State of Illinois and the United States
        and the General Corporation Law of the State of Delaware and, in
        rendering such opinion, may rely as to matters of fact, to the extent
        they deem proper, on certificates of responsible officers of the Company
        and public officials.

        (c) Each Agent shall have received from Mayer, Brown & Platt, counsel
for the Agents, such opinion or opinions, dated the date hereof, with respect to
the issuance and sale of the Notes, the Indenture, the Registration Statement,
the Prospectus and other related matters as the Agents may reasonably require,
and the Company shall have furnished to such counsel such documents as they
request for the purpose of enabling them to pass upon such matters.

        (d) The Company shall have furnished to each Agent a certificate of the
Company, signed by the Chairman of the Board, the President or any Vice
President and by the principal financial or accounting officer of the Company,
dated the date hereof, to the effect that the signers of such certificate have
carefully examined the Registration Statement, the Prospectus and this Agreement
and that:

                                      13

<PAGE>
 
              (i) the representations and warranties of the Company in this
        Agreement are true and correct in all material respects on and as of the
        date hereof with the same effect as if made on the date hereof and the
        Company has complied with all the agreements and satisfied all the
        conditions on its part to be performed or satisfied as a condition to
        the obligation of the Agents to solicit offers to purchase the Notes;

              (ii) no stop order suspending the effectiveness of the
        Registration Statement has been issued and no proceedings for that
        purpose have been instituted or, to the Company's knowledge, threatened;
        and

              (iii) since the date of the most recent financial statements
        included in the Prospectus, there has been no material adverse change in
        the condition (financial or other), earnings, business or properties of
        the Company and its subsidiaries, whether or not arising from
        transactions in the ordinary course of business, except as set forth in
        or contemplated in the Prospectus.

        (e) At the date hereof, Price Waterhouse shall have furnished to the
Agents a letter or letters (which may refer to letters previously furnished to
the Agents), dated as of the date hereof, in form and substance satisfactory to
the Agents and Price Waterhouse, confirming that they are independent
accountants with respect to the Company within the meaning of the Act and the
applicable published rules and regulations thereunder and stating in effect
that:

              (i) in their opinion, the consolidated financial statements
        (including financial schedules) of the Company and its subsidiaries
        examined by and reported on by them and included or incorporated by
        reference in the Registration Statement and the Prospectus comply as to
        form in all material respects with the applicable accounting
        requirements of the Act and the Exchange Act and the related published
        rules and regulations thereunder with respect to registration statements
        on Form S-3;

              (ii) on the basis of procedures of review in accordance with
        standards established by the American Institute of Certified Public
        Accountants (but not an audit in accordance with generally accepted
        auditing standards) consisting of:

                    (1) reading the minutes of meetings of the stockholders and
              the Board of Directors of the Company as set forth in the minute
              books through a specified date not more than five business days
              prior to the date of delivery of such letter;

                    (3)  making inquiries of certain officials of the Company 
              who have responsibilities for financial and accounting matters

              requested below;
               
              nothing has come to their attention as a result of the foregoing
              procedures that caused them to believe that:

                    generally accepted accounting principles;

                      (C)  (i) with respect to the period subsequent to the 
                    date of the most recent financial statements (other than any

                    incorporated by reference in the Registration Statement and
                    the Prospectus, at the date of the latest available interim

                    incorporated by reference and except when such data is not
                    prepared by or available from the Company, there was any

                    the Prospectus do not agree with the corresponding amounts
                    in the unaudited or audited consolidated financial
                    statements from which such amounts were derived or were not
                    determined on a basis substantially consistent with that of
                    the corresponding amounts in the audited financial
                    statements included or incorporated by reference in the
                    Registration Statement and the Prospectus.

              (iii) they have performed certain other specified procedures as a
        result of which they determined that certain information of an
        accounting, financial or statistical nature (which is limited to
        accounting, financial or statistical information derived from the
        general accounting records of the Company and its subsidiaries and
        subject to the Company's system of internal accounting controls relating
        to the preparation of the financial statements) set forth or
        incorporated by reference in the Registration Statement and the
        Prospectus, as amended or supplemented, including Exhibit 12 to the
        Registration Statement and the information included or incorporated in
        Items 1, 6 and 7 of the Company's Annual Report on Form 10-K and in
        "Management's Discussion and Analysis of Financial Condition and Results
        of Operations" included or incorporated by reference in any of the
        Company's Quarterly Reports on Form 10-Q, agrees with the accounting
        records of the Company and its subsidiaries, excluding any questions of
        legal interpretation; and

              (iv) if unaudited pro forma financial statements are included or
        incorporated by reference in the Registration Statement and the
        Prospectus, on the basis of a reading of the unaudited pro forma
        financial statements, carrying out certain specified procedures,
        inquiries of certain officials of the Company and the acquired company
        who have responsibility for financial and accounting matters, and
        proving the arithmetic accuracy of the pro forma financial statements,
        nothing came to their attention which caused them to believe that the
        pro forma financial statements were not properly compiled on the pro
        forma bases set forth in the notes thereto.

        References to the Registration Statement and the Prospectus in this 
paragraph (e) are to such documents as amended and supplemented at the date of
the letter.

        (f)  Subsequent to the respective dates as of which information is 
given in the Registration Statement and the Prospectus, there shall not have
been (i) any change or decrease specified in the letter or letters referred to
in paragraph (e) of this Section 5, except as otherwise disclosed in the
Prospectus or incorporated by reference or (ii) any change, or any development
involving a prospective change, in or affecting the business or properties of,
the Company and its subsidiaries the effect of which, in any case referred to in
clause (i) or (ii) above, is, in the judgment of each Agent, so material and
adverse as to make it impractical or inadvisable to proceed with the soliciting
of offers to purchase the Notes as contemplated by the Registration Statement
and the Prospectus.

        (g) Prior to the date hereof, the Company shall have furnished to each
Agent such further information, certificates and documents as such Agent may
reasonably request.

   7.  Right of Person Who Agreed to Purchase to Refuse to Purchase.  The
Company agrees that any person who has agreed to purchase and pay for any Note,
including a Purchaser and any person who purchases pursuant to a solicitation by
any of the Agents, shall have the right to refuse to purchase such Note if, at
the Closing Date therefor, either (a) any condition set forth in Section 5 or 6,
as applicable, shall not be satisfied or (b) subsequent to the agreement to
purchase such Note, any change, or any development involving a prospective
change, in or affecting the business or properties of the Company and its
subsidiaries shall have occurred the effect of which is, in the judgment of such
Purchaser or the Agent which presented the offer to purchase such Note, as
applicable, so material and adverse as to make it impractical or inadvisable to
proceed with the delivery of such Note.

   8.  Indemnification and Contribution.  (a)  The Company agrees to indemnify
and hold harmless each of you and each person who controls each of you within
the meaning of either the Act or the Exchange Act against any and all losses,
claims, damages or liabilities, joint or several, to which they or any of you or
them may become subject under the Act, the Exchange Act or other Federal or
state statutory law or regulation, at common law or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of a
material fact contained in the registration statement for the registration of
the Securities as originally filed or in any amendment thereof, or in the
Prospectus or any preliminary Prospectus, or in any amendment thereof or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and agrees to reimburse
each such indemnified party, for any legal or other expenses reasonably incurred
by them in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that (i) the Company will not be
liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon any such untrue statement or alleged
untrue statement or omission or alleged omission made therein in reliance upon
and in conformity with written information furnished to the Company by or on
behalf of such of you specifically for use therein or arises out of or is based
on the Statement of Eligibility (Form T-1) under the Trust Indenture Act of the
Trustee and (ii) such indemnity with respect to the Prospectus, in the form
included in the registration statement as filed, any Preliminary Prospectus or
any preliminary Prospectus Supplement shall not inure to the benefit of any
Agent (or any person controlling such Agent) through which the person asserting
any such loss, claim, damage or liability purchased the Notes which are the
subject thereof if such person did not receive a copy of the Prospectus
Supplement (or the Prospectus Supplement as amended or supplemented) excluding
documents incorporated therein by reference at or prior to the confirmation of
the sale of such Notes to such person in any case where such delivery is
required by the Act and the untrue statement or omission of a material fact
contained in the Prospectus, in the form included in the registration statement
as filed, any Preliminary Prospectus or any preliminary Prospectus Supplement
was corrected in the Prospectus Supplement (or the Prospectus Supplement as
amended or supplemented).  This indemnity agreement will be in addition to any
liability which the Company may otherwise have.

                                       18

<PAGE>
 
   (b)  Each of you agrees to indemnify and hold harmless the Company, each of
its directors, each of its officers who signs the Registration Statement, and
each person who controls the Company within the meaning of either the Act or the
Exchange Act, to the same extent as the foregoing indemnity from the Company to
you, but only with reference to written information relating to such of you
furnished to the Company by or on behalf of such of you specifically for use in
the documents referred to in the foregoing indemnity.  This indemnity agreement
will be in addition to any liability which you may otherwise have.

   (c)  Promptly after receipt by an indemnified party under this Section 8 of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 8, notify the indemnifying party in writing of the commencement thereof;
but the omission so to notify the indemnifying party will not relieve it from
any liability which it may have to any indemnified party otherwise than under
this Section 8.  In case any such action is brought against any indemnified
party, and it notifies the indemnifying party of the commencement thereof, the
indemnifying party will be entitled to participate therein, and to the extent
that it may elect by written notice delivered to the indemnified party promptly
after receiving the aforesaid notice from such indemnified party, to assume the
defense thereof, with counsel satisfactory to such indemnified party; provided,
however, that if the defendants in any such action include both the indemnified
party and the indemnifying party and the indemnified party shall have reasonably
concluded that there may be legal defenses available to it and/or other
indemnified parties which are different from or additional to those available to
the indemnifying party, the indemnified party or parties shall have the right to
select separate counsel to assert such legal defenses and to otherwise
participate in the defense of such action on behalf of such indemnified party or
parties.  Upon receipt of notice from the indemnifying party to such indemnified
party of its election so to assume the defense of such action and approval by
the indemnified party of counsel, the indemnifying party will not be liable to
such indemnified party under this Section 8 for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof unless (i) the indemnified party shall have employed separate counsel in
connection with the assertion of legal defenses in accordance with the proviso
to the next preceding sentence (it being understood, however, that the
indemnifying party shall not be liable for the expenses of more than one
separate counsel (other than local counsel used principally to facilitate local
litigation), approved by you in the case of paragraph (a) of this Section 8,
representing the indemnified parties under such paragraph (a) who are parties to
such action), (ii) the indemnifying party shall not have employed counsel
satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after notice of commencement of the action or (iii) the
indemnifying party has authorized the employment of counsel for the indemnified
party at the expense of the indemnifying party; and except that, if clause (i)
or (iii) is applicable, such liability shall be only in respect of the counsel
referred to in such clause (i) or (iii). The indemnifying party 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 (after
all rights to appeal have been exhausted) for the plaintiff, the indemnifying
party agrees to indemnify the indemnified party from and against any loss or
liability by reason of such settlement or judgment. Notwithstanding the
foregoing sentence, if at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for reasonable fees and
expenses of counsel required to be paid by this Section 8(c), the indemnifying
party 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 90 days after receipt by such indemnifying party of the aforesaid request
and (ii) such indemnifying party shall not have reimbursed the indemnified party
in accordance with such aforesaid request prior to the date of such settlement.
No indemnifying party shall, without the prior written consent of the
indemnified party (which consent shall not be unreasonably withheld), effect any
settlement of any pending or threatened proceeding in respect of which any
indemnified party is a party unless such settlement includes an unconditional
release of such indemnified party from all liability on claims that are the
subject matter of such proceeding.

                                       19

<PAGE>
 
   (d) In order to provide for just and equitable contribution in circumstances
in which the indemnification provided for in paragraph (a) of this Section 8 is
due in accordance with its terms but is for any reason held by a court to be
unavailable from the Company on grounds of policy or otherwise, the Company and
each of you shall contribute to the aggregate losses, claims, damages and
liabilities (including legal or other expenses reasonably incurred in connection
with investigating or defending same) to which the Company and such of you may
be subject in such proportion so that each of you is responsible for that
portion represented by the percentage that the aggregate commissions received by
you individually pursuant to Section 2 in connection with the Notes from which
such losses, claims, damages and liabilities arise (or, in the case of Notes
sold pursuant to a Terms Agreement, the aggregate commissions that would have
been received by you individually if such commissions had been payable), bears
to the aggregate principal amount of the Notes sold and the Company is
responsible for the balance; provided, however, that (y) in no case shall you
individually be responsible for any amount in excess of the commissions received
by you individually in connection with the Notes from which such losses, claims,
damages and liabilities arise (or, in the case of Notes sold pursuant to a Terms
Agreement, the aggregate commissions that would have been received by you
individually if such commissions had been payable), and (z) no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.  For purposes of this Section 8, each person who
controls each of you within the meaning of the Act shall have the same rights to
contribution as you and each person who controls the Company within the meaning
of either the Act or the Exchange Act, each officer of the Company who shall
have signed the Registration Statement and each director of the Company shall
have the same rights to contribution as the Company, subject in each case to
clause (y) of this paragraph (d).  Any party entitled to contribution will,
promptly after receipt of notice of commencement of any action, suit or
proceeding against such party in respect of which a claim for contribution may
be made against another party or parties under this paragraph (d), notify such
party or parties from whom contribution may be sought, but the omission to so
notify such party or parties shall not relieve the party or parties from whom
contribution may be sought from any other obligation it or they may have
hereunder or otherwise than under this paragraph (d).

   9.   Termination  (a) This Agreement will continue in effect until terminated
as provided in this Section 9.  This Agreement may be terminated by either the
Company as to any of you or by any of you insofar as this Agreement relates to
you by giving written notice of such termination to you or the Company, as the
case may be; provided, however, that for so long as is required by the Act, the
Company shall keep available a current Prospectus meeting the requirements of
the Act and shall file all amendments and supplements under the Act required for
that purpose.  This Agreement shall so terminate at the close of business on the
first business day following the receipt of such notice by the party to whom
such notice is given.  In the event of such termination, no party shall have any
liability to the other party hereto, except as provided in the fourth paragraph
of Section 2(a) with respect to unpaid commissions, Section 4(g), Section 8 and
Section 10.

  (b)  Each Terms Agreement shall be subject to termination in the absolute
discretion of the Purchaser, by notice given to the Company prior to delivery of
any payment for Notes to be

                                       20

<PAGE>
 
purchased thereunder, if prior to such time (i) there has been, since the date
of such Terms Agreement or since the respective dates as of which information is
given in the Registration Statement, any material adverse change in the
condition, financial or otherwise, or in the earnings, business affairs or
business prospects of the Company and its subsidiaries considered as one
enterprise, whether or not arising in the ordinary course of the business, (ii)
trading in the Company's common stock shall have been suspended by the
Commission or the New York Stock Exchange or trading in securities generally on
the New York Stock Exchange shall have been suspended or limited or minimum
prices shall have been established on such Exchange, (iii) a banking moratorium
shall have been declared either by Federal or New York State authorities, (iv)
there shall have occurred any material adverse change in the financial markets
in the United States or any outbreak or escalation of hostilities or other
national or international calamity or crisis the effect of which is such as to
make it, in the judgment of the Purchaser, impracticable to market such Notes or
enforce contracts for the sale of such Notes, or (v) there shall have been,
subsequent to the agreement to purchase such Note, any downgrading in the rating
accorded the Company's debt securities by any "nationally recognized statistical
rating organization" (as defined for purposes of Rule 426(g) under the Act).

   10.  Representation and Indemnities to Survive  The respective agreements,
representations, warranties, indemnities and other statements of the Company or
its officers and of you set forth in or made pursuant to this Agreement will
remain in full force and effect, regardless of any investigation made by or on
behalf of either of you or the Company or any of the officers, directors or
controlling persons referred to in Section 8 hereof, and will survive delivery
of and payment for the Notes.  The provisions of Section 4(g) and 8 hereof shall
survive the termination or cancellation of this Agreement.

   11.  Notices  All communications hereunder will be in writing and effective
only on receipt, and, if sent to either of you, will be mailed, delivered or
telegraphed and confirmed to such of you, at the addresses specified in Schedule
I hereto; or if sent to the Company, will be mailed, delivered or telegraphed
and confirmed to it at Tribune Company, 435 North Michigan Avenue, Chicago,
Illinois, 60611, attention of David J. Granat, Vice President and Treasurer
(with a copy to the General Counsel of Tribune Company).

   12.  Successors  This Agreement will inure to the benefit of and be binding
upon the parties hereto and their respective successors and the officers and
directors and controlling persons referred to in Section 8 hereof, and no other
person will have any right or obligation hereunder, except as otherwise provided
in Section 7 hereof.

   13.  Applicable Law  This Agreement will be governed by and construed in
accordance with the laws of the State of New York.

   14.  Counterparts  This Agreement and any amendments hereto may be executed
in any number of counterparts, each of which shall be deemed to be an original
but all of which together shall constitute but one agreement.

                                TRIBUNE COMPANY

                           ADMINISTRATIVE PROCEDURES

               FOR FIXED RATE AND FLOATING RATE MEDIUM-TERM NOTES
                         (DATED AS OF APRIL ___, 1996)


          Medium-Term Notes Due Nine Months or More From Date of Issue (the
"Notes") are to be offered on a continuous basis by TRIBUNE COMPANY, a Delaware
corporation (the "Company"), to or through Merrill Lynch & Co., Merrill Lynch,
Pierce, Fenner & Smith Incorporated, Goldman, Sachs & Co. and Salomon Brothers
Inc (each, an "Agent" and, collectively, the "Agents") pursuant to a Selling
Agency Agreement, dated April ___, 1996 (the "Selling Agency Agreement"), by and
among the Company and the Agents. The Selling Agency Agreement provides both for
the sale of Notes by the Company to one or more of the Agents as principal for
resale to investors and other purchasers and for the sale of Notes by the
Company directly to investors (as may from time to time be agreed to by the
Company and the related Agent or Agents), in which case each such Agent will act
as an agent of the Company in soliciting purchases of Notes.

          Unless otherwise agreed by the related Agent or Agents and the
Company, Notes will be purchased by the related Agent or Agents as principal.
Such purchases will be made in accordance with terms agreed upon by the related
Agent or Agents and the Company (which terms shall be agreed upon orally, with
written confirmation prepared by the related Agent or Agents and mailed to the
Company).  If agreed upon by any Agent or Agents and the Company, the Agent or
Agents, acting solely as agent or agents for the Company and not as principal,
will use reasonable best efforts to solicit offers to purchase the Notes.  Only
those provisions in these Administrative Procedures that are applicable to the
particular role to be performed by the related Agent or Agents shall apply to
the offer and sale of the relevant Notes.

          The Notes will be issued as a series of debt securities under an
Indenture, dated as of March 1, 1992, as amended, supplemented or modified from
time to time (the "Indenture"), between the Company and First Trust of Illinois,
National Association, as successor trustee (together with any successor in such
capacity, the "Trustee").  The Company has filed a Registration Statement with
the Securities and Exchange Commission (the "Commission") registering debt
securities and warrants to purchase debt securities (which includes the Notes)
(the "Registration Statement", which term shall include any additional
registration statements filed in connection with the Notes).  The most recent
base prospectus deemed part of the Registration Statement, as supplemented with
respect to the Notes, is herein referred to as "Prospectus".  The most recent
supplement to the Prospectus setting forth the purchase price, interest rate or
formula, maturity date and other terms of the Notes (as applicable) is herein
referred to as the "Pricing Supplement".

                                      B-1

<PAGE>
 
          The Notes will either be issued (a) in book-entry form and represented
by one or more fully registered Notes without coupons (each, a "Global Note")
delivered to the Trustee, as agent for The Depository Trust Company ("DTC"), and
recorded in the book-entry system maintained by DTC, or (b) in certificated form
(each, a "Certificated Note") delivered to the investor or other purchaser
thereof or a person designated by such investor or other purchaser.

          General procedures relating to the issuance of all Notes are set forth
in Part I hereof.  Additionally, Notes issued in book-entry form will be issued
in accordance with the procedures set forth in Part II hereof and Certificated
Notes will be issued in accordance with the procedures set forth in Part III
hereof.  Capitalized terms used but not otherwise defined herein shall have the
meanings ascribed thereto in the Indenture or the Notes, as the case may be.


                         PART I:  PROCEDURES OF GENERAL
                                 APPLICABILITY


Date of Issuance/Authentication:  

Each Note will be dated as of the date of its authentication by the Trustee.
Each Note shall also bear an original issue date (each, an "Original Issue
Date"). The Original Issue Date shall remain the same for all Notes subsequently
issued upon transfer, exchange or substitution of an original Note regardless of
their dates of authentication.

Maturities:  

Each Note will mature on a date nine months or more from its Original Issue Date
(the "Stated Maturity Date") selected by the investor or other purchaser and
agreed to by the Company.

Registration:  

Unless otherwise provided in the applicable Pricing Supplement, Notes will be
issued only in fully registered form.

Denominations:  

Unless otherwise provided in the applicable Pricing Supplement, the Notes will
be issued in denominations of $1,000 and integral multiples thereof.

Interest Rate Bases applicable to Floating Rate Notes:

Unless otherwise provided in the applicable Pricing Supplement, Floating
Rate Notes will bear interest at a rate or rates determined by reference to the
CD Rate, the CMT Rate, the Commercial Paper Rate, the Eleventh District Cost of

                                      B-2
<PAGE>
 
Funds Rate, the Federal Funds Rate, LIBOR, the Prime Rate, the Treasury Rate, or
such other interest rate basis or formula as may be set forth in applicable
Pricing Supplement, or by reference to two or more such rates, as adjusted by
the Spread and/or Spread Multiplier, if any, applicable to such Floating Rate
Notes.

Redemption/Repayment:  

The Notes will be subject to redemption by the Company in accordance with the
terms of the Notes, which will be fixed at the time of sale and set forth in the
applicable Pricing Supplement. If no Initial Redemption Date is indicated with
respect to a Note, such Note will not be redeemable prior to its Stated Maturity
Date.

The Notes will be subject to repayment at the option of the Holders thereof in
accordance with the terms of the Notes, which will be fixed at the time of sale
and set forth in the applicable Pricing Supplement.  If no Optional Repayment
Date is indicated with respect to a Note, such Note will not be repayable at the
option of the Holder prior to its Stated Maturity Date.

Calculation of Interest:
  
In case of Fixed Rate Notes, interest (including payments for partial periods)
will be calculated and paid on the basis of a 360-day year of twelve 30-day
months.

The interest rate on each Floating Rate Note will be calculated by reference to
the specified Interest Rate Basis or Bases plus or minus the applicable Spread,
if any, and/or multiplied by the applicable Spread Multiplier, if any.

Unless otherwise provided in the applicable Pricing Supplement, interest on each
Floating Rate Note will be calculated by multiplying its face amount by an
accrued interest factor.  Such accrued interest factor is computed by adding the
interest factor calculated for each day in the period for which accrued interest
is being calculated.  Unless otherwise provided in the applicable Pricing
Supplement, the interest factor for each such day is computed by dividing the
interest rate applicable to such day by 360 if the CD Rate, Commercial Paper
Rate, Eleventh District Cost of Funds Rate, Federal Funds Rate, LIBOR or Prime
Rate is an applicable Interest Rate Basis, or by the actual number of days in
the year if the CMT Rate or Treasury Rate is an applicable Interest Rate Basis.
As provided in the applicable Pricing Supplement,

                                      B-3
<PAGE>
 
the interest factor for Notes for which the interest rate is calculated with
reference to two or more Interest Rate Bases will be calculated in each period
in the same manner as if only one of the applicable Interest Rate Bases applied
as specified in the applicable Pricing Supplement and the Notes.

Interest:  

General. Each Note will bear interest in accordance with its terms. Unless
otherwise provided in the applicable Pricing Supplement, interest on each Note
will accrue from and including the Original Issue Date of such Note for the
first interest period or from the most recent Interest Payment Date (as defined
below) to which interest has been paid or duly provided for all subsequent
interest periods to but excluding applicable Interest Payment Date or the Stated
Maturity Date or date of earlier redemption or repayment, as the case may be
(the Stated Maturity Date or date of earlier redemption or repayment is referred
to herein as the "Maturity Date" with respect to the principal repayable on such
date).

If an Interest Payment Date or the Maturity Date with respect to any Fixed Rate
Note falls on a day that is not a Business Day (as defined below), the required
payment to be made on such day need not be made on such day, but may be made on
the next succeeding Business Day with the same force and effect as if made on
such day, and no interest shall accrue on the amount so payable for the period
from and after such Interest Payment Date or Maturity, as the case may be.  If
an Interest Payment Date other than the Maturity Date with respect to any
Floating Rate Note would otherwise fall on a day that is not a Business Day,
such Interest Payment Date will be postponed to the next succeeding Business
Day, except that in the case of a Note for which LIBOR is an applicable Interest
Rate Basis, if such Business Day falls in the next succeeding calendar month,
such Interest Payment Date will be the immediately preceding Business Day.  If
the Maturity Date with respect to any Floating Rate Note falls on a day that is
not a Business Day, the required payment to be made on such day need not be made
on such day, but may be made on the next succeeding Business Day with the same
force and effect as if made on such day, and no interest shall accrue from and
after such Maturity.  Unless otherwise provided in the applicable Pricing
Supplement, "Business Day" means any day that is not a day on which banking
institutions are authorized or required by law, regulation or executive order to
close in The City of New York; provided, however, that, with respect to Notes
the payment of which is to be made in a currency

                                      B-4
<PAGE>
 
other than U.S. dollars or composite currencies (such currency or composite
currency in which a Note is denominated is the "Specified Currency"), such day
is also not a day on which banking institutions are authorized or required by
law, regula tion or executive order to close in the Principal Financial Center
(as defined below) of the country issuing such Specified Currency or, in the
case of European Currency Units ("ECUs"), is not a day that is designated as an
ECU non-settlement day by the ECU Banking Association in Paris or otherwise
generally regarded in the ECU interbank market as a day on which payments on
ECUs shall not be made; provided, further, that, with respect to Notes for which
LIBOR is an applicable Interest Rate Basis, such day is also a London Business
Day (as defined below).  "London Business Day" means (i) if the currency
(including composite currencies) specified in the applicable Pricing Supplement
as the currency (the "Index Currency") for which LIBOR is calculated is other
than ECU, any day on which dealings in such Index Currency are transacted in the
London interbank market or (ii) if the Index Currency is ECU, any day that is
not designated as an ECU non-settlement day by the ECU Banking Association in
Paris or otherwise generally regarded in the ECU interbank market as a day on
which payments on ECUs shall not be made.  It being understood that if no such
currency or composite currency is specified in the applicable Pricing
Supplement, the Index Currency shall be U.S. dollars.  "Principal Financial
Center" means the capital city of the country issuing the currency or composite
currency in which any payment in respect of the Notes is to be made or, solely
with respect to the calculation of LIBOR, the Index Currency, except that with
respect to U.S. dollars, Australian dollars, Deutsche marks, Dutch guilders,
Italian lire, Swiss francs and ECUs, the Principal Financial Center shall be The
City of New York, Sydney, Frankfurt, Amsterdam, Milan, Zurich and Luxembourg,
respectively.

Regular Record Dates.  Unless otherwise provided in the applicable Pricing
Supplement, the "Regular Record Date" for a Note shall be the date 15 calendar
days (whether or not a Business Day) preceding the applicable Interest Payment
Date.

Interest Payment Dates.  Interest payments will be made on each Interest Payment
Date commencing with the first Interest Payment Date following the Original
Issue Date; provided, however, the first payment of interest on any Note
originally issued between a Regular Record Date and an Interest

                                      B-5
<PAGE>
 
Payment Date will occur on the Interest Payment Date following the next
succeeding Regular Record Date.

Unless otherwise provided in the applicable Pricing Supplement, interest
payments on Fixed Rate Notes will be made semiannually in arrears on May 15 and
November 15 of each year and on the Maturity Date, while interest payments on
Floating Rate Notes will be made as specified in the applicable Pricing
Supplement.

Acceptance and Rejection of Offers from Solicitation as Agents:

If agreed upon by any Agent and the Company, then such Agent acting solely as
agent for the Company and not as principal will solicit purchases of the Notes.
Each Agent will communicate to the Company, orally or in writing, each
reasonable offer to purchase Notes solicited by such Agent on an agency basis,

relevant Notes or its agent.  Pursuant to Rule 434 ("Rule 434") of the
Securities Act of 1933, as amended, the Pricing Supplement may be delivered
separately from the Prospectus.  Outdated Pricing Supplements (other than those
retained for files) will be destroyed.

Settlement:

The receipt of immediately available funds by the Company in payment for a Note
and the authentication and delivery of such Note shall, with respect to such
Note, constitute "settlement". Offers accepted by the Company will be settled
three Business Days, or at such time as the purchaser, the applicable Agent and
the Company shall agree, pursuant to the timetable for settlement set forth in
Parts II and III hereof under "Settlement Procedure Timetable" with respect to
Global Notes and Certificated Notes, respectively (each such date fixed for

<PAGE>
 
not completed on or before the time set forth under the applicable "Settlement
Procedures Timetable", such offer shall not be settled until the Business Day
following the completion of settlement procedures A and B or such later date as
the purchaser and the Company shall agree.

The foregoing settlement procedures may be modified with respect to any purchase
of Notes by an Agent as principal if so agreed by the Company and such Agent.

Procedure for Changing Rates or Other Variable Terms:

When a decision has been reached to change the interest rate or any other
variable term on any Notes being sold by the Company, the Company will promptly
advise the Agents and the Trustee by facsimile transmission and the Agents will
forthwith suspend solicitation of offers to purchase such Notes. The Agents will
telephone the Company with recommendations as to the changed interest rates or
other variable terms. At such time as the Company notifies the Agents and the
Trustee of the new interest rates or other variable terms, the Agents may resume
solicitation of offers to purchase such Notes. Until such time, only
"indications of interest" may be recorded. Immediately after acceptance by the
Company of an offer to purchase Notes at a new interest rate or new variable
term, the Company, the Offering Agent and the Trustee shall follow the
procedures set forth under the applicable "Settlement Procedures".

Suspension of Solicitation; Amendment or Supplement:

The Company may instruct the Agents to suspend solicitation of offers to
purchase Notes at any time. Upon receipt of such instructions, the Agents will
forthwith suspend solicitation of offers to purchase from the Company until such
time as the Company has advised the Agents that solicitation of offers to
purchase may be resumed. If the Company decides to amend or supplement the
Registration Statement or the Prospectus (other than to establish or change
interest rates or formulas, maturities, prices or other similar variable terms
with respect to the Notes), it will promptly advise the Agents and will furnish
the Agents and their counsel with copies of the proposed amendment or
supplement. Copies of such amendment or supplement will be delivered or mailed
to the Agents, their counsel and the Trustee in quantities which such

Company is suspended (other than to  establish or change interest rates or
formulas, maturities, prices or other similar variable terms with respect to the
Notes) there shall be any offers to purchase Notes that have been accepted by
the Company which have not been settled, the Company will promptly advise the
Offering Agent and the Trustee whether such offers may be settled and whether
copies of the Prospectus as theretofore amended and/or supplemented as in effect
at the time of the suspension may be delivered in connection with the settlement
of such offers.  The Company will have the sole responsibility for such decision
and for any arrangements which may be made in the event that the Company
determines that such offers may not be settled or that copies of such Prospectus
may not be so delivered.

Delivery of Prospectus and applicable Pricing Supplement:

                     PART II:  PROCEDURES FOR NOTES ISSUED
                               IN BOOK-ENTRY FORM

          In connection with the qualification of Notes issued in book-entry
form 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
Representations from the Company and the Trustee to DTC, dated __________, 1996,
and a Certificate Agreement, dated _______________, 19__, between the Trustee
and DTC, as amended (the "Certificate Agreement"), and its obligations as a
participant in DTC, including DTC's Same-Day Funds Settlement System ("SDFS").

Issuance:

All Fixed Rate Notes issued in book-entry form having the same Original Issue
Date, Specified Currency, Interest Rate, Default Rate, Interest Payment Dates,
redemption and/or repayment terms, if any, and Stated Maturity Date
(collectively, the "Fixed Rate Terms") will be represented initially by a single
Global Note; and all Floating Rate Notes issued in book-entry form having the
same Original Issue Date, Specified Currency, Interest Category, formula for the
calculation of interest (including the Interest Rate Basis or Bases, which may
be the CD Rate, the CMT Rate, the Commercial Paper Rate, the Eleventh District
Cost of Funds Rate, the Federal Funds Rate, LIBOR, the Prime Rate or the
Treasury Rate or any other interest rate basis or formula, and Spread and/or
Spread Multiplier, if any), Day Count Convention, Initial Interest Rate, Default
Rate, Index Maturity (if applicable), Minimum Interest Rate, if any, Maximum
Interest Rate, if any, redemption and/or repayment terms, if any, Interest
Payment Dates, Initial Interest Reset Date, Interest Reset Dates and Stated
Maturity Date(collectively, the "Floating Rate Terms") will be represented
initially by a single Global Note.

<PAGE>
 
For other variable terms with respect to the Fixed Rate Notes and Floating Rate
Notes, see the Prospectus and the applicable Pricing Supplement.

Owners of beneficial interests in Global Notes will be entitled to physical
delivery of Certificated Notes equal in principal amount to their respective
beneficial interests only upon certain limited circumstances described in the
Prospectus.

Identification:

The Company has arranged with the CUSIP Service Bureau of Standard & Poor's
Corporation (the "CUSIP Service Bureau") for the reservation of one series of
CUSIP numbers, which series consists of approximately 900 CUSIP numbers which
have been reserved for and relate to Global Notes and the Company has delivered
to each of the Trustee and DTC such list of such CUSIP numbers. The Company will
assign CUSIP numbers to Global Notes as described below under Settlement
Procedure B. DTC will notify the CUSIP Service Bureau periodically of the CUSIP
numbers that the Company has assigned to Global Notes. The Trustee will notify
the Company at any time when fewer than 100 of the reserved CUSIP numbers remain
unassigned to Global Notes, and, if it deems necessary, the Company will reserve
and obtain additional CUSIP numbers for assignment to Global Notes. Upon
obtaining such additional CUSIP numbers, the Company will deliver a list of such
additional numbers to the Trustee and DTC. Notes issued in book-entry form in
excess of $200,000,000 (or the equivalent thereof in one or more foreign or
composite currencies) aggregate principal amount and otherwise required to be
represented by the same Global Note will instead be represented by two or more
Global Notes which shall all be assigned the same CUSIP number.

Registration:

Unless otherwise specified by DTC, each Global Note will be registered in the
name of Cede & Co., as nominee for DTC, on the register maintained by the
Trustee under the Indenture. The beneficial owner of a Note issued in book-entry
form (i.e., an owner of a beneficial interest in a Global 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 issued in book-entry form,
the "Participants") to act as agent for such beneficial 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 Note issued in book-entry form in the

                                      B-12
<PAGE>
 
account of such Participants.  The ownership interest of such beneficial owner
in such Note issued in book-entry form 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 beneficial ownership interests in a Global Note will be
accomplished 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 Global Note.

Exchanges:

The Trustee may deliver to DTC and the CUSIP Service Bureau at any time a
written notice specifying (a) the CUSIP numbers of two or more Global Notes
outstanding on such date that represent Global Notes having the same Fixed Rate
Terms or Floating Rate Terms, as the case may be (other than Original Issue
Dates), and for which interest has been paid to the same date; (b) a date,
occurring at least 30 days after such written notice is delivered and at least
30 days before the next Interest Payment Date for the related Notes issued in
book-entry form, on which such Global Notes shall be exchanged for a single
replacement Global Note; and (c) a new CUSIP number, obtained from the Company,
to be assigned to such replacement Global Note. 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 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 Notes to be exchanged will no longer be valid. On the specified exchange
date, the Trustee will exchange such Global Notes for a single Global Note
bearing the new CUSIP number and the CUSIP numbers of the exchanged Notes will,
in accordance with CUSIP Service Bureau procedures, be canceled and not
immediately reassigned. Notwithstanding the foregoing, if the Global Notes to be
exchanged exceed $200,000,000 (or the equivalent thereof in one or more foreign
or composite currencies) in aggregate principal amount, one replacement Note
will be authenticated and issued to represent each $200,000,000 (or the
equivalent thereof in one or more foreign or composite currencies) in aggregate
principal amount of the exchanged Global Notes and an additional Global Note or
Notes will be authenticated and issued to

                                      B-13
<PAGE>
 
represent any remaining principal amount of such Global Notes (See
"Denominations" below).

Denominations:

Unless otherwise provided in the applicable Pricing Supplement, Notes issued in
book-entry form will be issued in denominations of $1,000 and integral multiples
thereof. Global Notes will not be denominated in excess of $200,000,000 (or the
equivalent thereof in one or more foreign or composite currencies) aggregate
principal amount. If one or more Notes are issued in book-entry form in excess
of $200,000,000 (or the equivalent thereof in one or more foreign or composite
currencies) aggregate principal amount and would, but for the preceding
sentence, be represented by a single Global Note, then one Global Note will be
issued to represent each $200,000,000 (or the equivalent thereof in one or more
foreign or composite currencies) in aggregate principal amount of such Notes
issued in book-entry form and an additional Global Note or Notes will be issued
to represent any remaining aggregate principal amount of such Note or Notes
issued in book-entry form. In such a case, each of the Global Notes representing
Notes issued in book-entry form shall be assigned the same CUSIP number.

Payments of Principal and Interest:

Payments of Interest Only. Promptly after each Regular Record Date, the Trustee
will deliver to the Company and DTC a written notice specifying by CUSIP number
the amount of interest to be paid on each Global Note on the following Interest
Payment Date (other than an Interest Payment Date coinciding with the Maturity
Date) and the total of such amounts. DTC will confirm the amount payable on each
Global Note on such Interest Payment Date by reference to the daily bond reports
published by Standard & Poor's Corporation. On such Interest Payment Date, the
Company will pay to the Trustee in immediately available funds an amount
sufficient to pay the interest then due and owing on the Global Notes, and upon
receipt of such funds from the Company, the Trustee in turn will pay to DTC such
total amount of interest due on such Global Notes (other than on the Maturity
Date) which is payable in U.S. dollars, at the times and in the manner set forth
below under "Manner of Payment". The Trustee shall make payment of that amount
of interest due and owing on any Global Notes that Participants have elected to
receive in foreign or composite currencies directly to such Participants.

                                      B-14
<PAGE>
 
Notice of Interest Rates. Promptly after each Interest Determination Date or
Calculation Date, as the case may be, for Floating Rate Notes issued in book-
entry form, the Trustee will notify each of Moody's Investors Service, Inc. and
Standard & Poor's Corporation of the interest rates determined as of such
Interest Determination Date.

Payments at Maturity.  On or about the first Business Day of each month, the
Trustee will deliver to the Company and DTC a written list of principal,
premium, if any, and interest to be paid on each Global Note maturing or
otherwise becoming due in the following month.  The Trustee, the Company and DTC
will confirm the amounts of such principal, premium, if any, and interest
payments with respect to each such Global Note on or about the fifth Business
Day preceding the Maturity Date of such Global Note.  On the Maturity Date, the
Company will pay to the Trustee in immediately available funds an amount
sufficient to make the required payments, and upon receipt of such funds the
Trustee in turn will pay to DTC the principal amount of Global Notes, together
with premium, if any, and interest due on the Maturity Date, which are payable
in U.S. dollars, at the times and in the manner set forth below under "Manner of
Payment".  The Trustee shall make payment of the principal, premium, if any, and
interest to be paid on the Maturity Date of each Global Note that Participants
have elected to receive in foreign or composite currencies directly to such
Partici pants.  Promptly after (i) payment to DTC of the principal, premium, if
any, and interest due on the Maturity Date of such Global Note which are payable
in U.S. dollars and (ii) payment of the principal, premium, if any, and interest
due on the Maturity Date of such Global Note to those Participants who have
elected to receive such payments in foreign or composite currencies, the Trustee
will cancel such Global Note and deliver it to the Company with an appropriate
debit advice.  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 Global Notes as of the close of business on the immediately
preceding Business Day.

Manner of Payment.  The total amount of any principal, premium, if any, and
interest due on Global Notes on any Interest Payment Date or the Maturity Date,

such date. The Company will make such payment on such Global Notes to an account
specified by the Trustee. Upon receipt of such funds, the Trustee will pay by
separate wire transfer (using Fedwire message entry instructions in a form
previously specified by DTC) to an account at the Federal Reserve Bank of New
York previously specified by DTC, in funds available for immediate use by DTC,
each payment in U.S. dollars of principal, premium, if any, and interest due on
Global Notes on such date. Thereafter on such date, DTC will pay, in accordance
with its SDFS operating procedures then in effect, such amounts in funds
available for immediate use to the respective Participants in whose names the
beneficial interests in such Global Notes are recorded in the book-entry system
maintained by DTC. Neither the Company nor the Trustee shall have any
responsibility or liability for the payment in U.S. dollars by DTC of the
principal of, or premium, if any, or interest on, the Global Notes. The Trustee
shall make all payments of principal, premium, if any, and interest on each
Global Note that Participants have elected to receive in foreign or composite
currencies directly to such Participants.

Withholding Taxes. The amount of any taxes required under applicable law to be
withheld from any interest payment on a Global Note will be determined and
withheld by the Participant, indirect participant in DTC or other Person
responsible for forwarding payments and materials directly to the beneficial
owner of such Global Note.

Settlement Procedures Timetable:             

For offers to purchase Notes accepted by the Company, Settlement Procedures A
through K set forth above shall be completed as soon as possible following the
trade but not later than the respective times (New York City time) set forth
below:

Settlement
Procedure            Time
- ----------           ----

    A                11:00 a.m. on the trade date or within one
                     hour following the trade
    B                12:00 noon on the trade date or within one
                     hour following the trade

                                      B-20
<PAGE>
 
    C      No later than the close of business on the trade date
    D      9:00 a.m. on Settlement Date
    E      10:00 a.m. on Settlement Date
    F-G    No later than 2:00 p.m. on Settlement Date
    H      4:00 p.m. on Settlement Date
    I-J    5:00 p.m. on Settlement Date


Settlement Procedure H is subject to extension in accordance with any extension
of Fedwire closing deadlines and in the other events specified in the SDFS
operating procedures in effect on the Settlement Date.

If settlement of a Note issued in book-entry form is rescheduled or canceled,
the Trustee will deliver to  DTC, through DTC's Participant Terminal System, a
cancellation message to such effect by no later than 5:00 p.m., New York City
time, on the Business Day immediately preceding the scheduled Settlement Date.

Failure to Settle:       

If the Trustee fails to enter an SDFS deliver order with respect to a Note
issued in book-entry form pursuant to Settlement Procedure F, the Trustee may
deliver to DTC, through DTC's Participant Terminal System, as soon as
practicable a withdrawal message instructing DTC to debit such Note to the
participant account of the Trustee maintained at DTC. DTC will process the
withdrawal message, provided that such participant account contains a principal
amount of the Global Note representing such Note that is at least equal to the
principal amount to be debited. If withdrawal messages are processed with
respect to all the Notes represented by a Global Note, the Trustee will mark
such Global Note "canceled", make appropriate entries in its records and send
certification of destruction of such canceled Global Note to the Company. The
CUSIP number assigned to such Global Note shall, in accordance with CUSIP
Service Bureau procedures, be canceled and not immediately reassigned. If
withdrawal messages are processed with respect to a portion of the Notes
represented by a Global Note, the Trustee will exchange such Global Note for two
Global Notes, one of which shall represent the Global Notes for which withdrawal
messages are processed and shall be canceled immediately after issuance and the
other of which shall represent the other Notes previously represented by the
surrendered Global Note

                                      B-21
<PAGE>
 
and shall bear the CUSIP number of the surrendered Global Note.

In the case of any Note in book-entry form sold through the Offering Agent, as
agent, if the purchase price for any such Note is not timely paid to the
Participants with respect thereto by the beneficial investor or other purchaser
thereof (or a person, including an indirect participant in DTC, acting on behalf
of such investor or other purchaser), such Participants and, in turn, the
related Offering 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. If such
failure shall have occurred for any reason other than default by the applicable
Offering Agent to perform its obligations hereunder or under the Selling Agency
Agreement, the Company will reimburse such Offering Agent on an equitable basis
for its reasonable loss of the use of funds during the period when the funds
were credited to the account of the Company.

Notwithstanding the foregoing, upon any failure to settle with respect to a Note
in book-entry form, DTC may take any actions in accordance with its SDFS
operating procedures then in effect.  In the event of a failure to settle with
respect to a Note that was to have been represented by a Global Note also
representing other Notes, the Trustee will provide, in accordance with
Settlement Procedure D, for the authentication and issuance of a Global Note
representing such remaining Notes and will make appropriate entries in its
records.

calendar days prior to the applicable Interest Payment Date.

premium, if any, and interest to be paid on Certificated Notes maturing in the
next succeeding month.  The Trustee will be responsible for withholding taxes on

other manner which the Trustee deems; sufficient.

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

days prior to the first solicitation of the written instruments required for

authorized proxies) shall be the only Persons entitled to execute written
instruments with respect to such Act, or to revoke any written instrument
previously delivered, whether or not such Persons shall continue to be Holders

instrument shall be valid or effective for more than 150 days after such record
date.

or other 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

                                     -10-

by such event, at his address as it appears in the Security Register, not later
than the latest date, and not earlier than the earliest date, prescribed for the
giving of such notice provided, however, that, in any case, any notice to
Holders of Floating Rate Securities regarding the determination of a periodic
rate of interest, if such notice is required pursuant to Section 3.01, shall be
sufficiently given if given in the manner specified pursuant to Section 3.01. In
any case where notice to Holders is given by mail, neither the failure to mail
such 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

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

a condition precedent to the validity of any action taken in reliance upon such
waiver.

then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

imposed by operation of Section 318(c) of the Trust Indenture Act, the imposed

          (a) If the Company shall establish pursuant to Section 3.01 that the
Securities of a particular series 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, in accordance with Section 3.03 and the Company Order delivered
to the Trustee thereunder, authenticate and deliver, such Global Security or
Securities, which (i) shall represent, and shall be denominated in an amount
equal to the aggregate principal amount of, the Outstanding Securities of such
series to be represented by such Global Security or Securities, (ii) shall be
registered in the name of the Depository for such Global Security or Securities
or its nominee, (iii) shall be delivered by the Trustee to the Depository or
pursuant to the Depository's instruction and (iv) shall bear a legend
substantially to the following effect: "THIS GLOBAL SECURITY MAY NOT BE
TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITORY OR BY A NOMINEE OF THE
DEPOSITORY TO THE DEPOSITORY OR ANOTHER NOMINEE OF THE DEPOSITORY OR BY THE
DEPOSITORY OR ANY SUCH NOMINEE TO A SUCCESSOR OF THE DEPOSITORY OR A NOMINEE OF
SUCH SUCCESSOR DEPOSITORY."

          (b) Notwithstanding any other provision of this Section 2.03 or of
Section 3.05, unless otherwise provided in the Global Security, a Global
Security may be transferred, in whole but not in part and in the manner provided
in Section 3.05, only to the Depository or another nominee of the Depository for
such

                                      -14-
<PAGE>
 
Global Security, or to a successor Depository for such Global Security selected
or approved by the Company or to a nominee of such successor Depository. Except
as provided below, owners solely of beneficial interests in a Global Security
shall not be entitled to receive physical delivery of the Securities represented
by such Global Security and will not be considered the Holders thereof for any
purpose under the Indenture.

          (c) (i) If at any time the Depository for a Global Security notifies
the Company that it is unwilling or unable to continue as Depository for such
Global Security or if at any time the Depository for the Securities for such
series shall no longer be eligible or in good standing under the Securities
Exchange Act of 1934, as amended, or other applicable statute or regulation, the
Company shall appoint a successor Depository with respect to such Global
Security. If a successor Depository for such Global Security is not appointed by
the Company within 90 days after the Company receives such notice or becomes
aware of such ineligibility, the Company's election pursuant to Section
3.01(16) shall no longer be effective with respect to such Global Security and
the Company will execute, and the Trustee, upon receipt of a Company Order for
the authentication and delivery of individual Securities of such series in
exchange for such Global Security, will authenticate and deliver individual
Securities of such series of like tenor and terms in definitive form in an
aggregate principal amount equal to the principal amount of the Global Security
in exchange for such Global Security.

          (ii) The Company may at any time and in its sole discretion determine
that the Securities of any series issued or issuable in the form of one or more
Global Securities shall no longer be represented by such Global Security or
Securities. In such event the Company will execute, and the Trustee, upon
receipt of a Company Order for the authentication and delivery of individual
Securities of such series in exchange in whole or in part for such Global
Security, will authenticate and deliver individual Securities of such series of
like tenor and terms in definitive form in an aggregate principal amount equal
to the principal amount of such Global Security or Securities representing such
series in exchange for such Global Securities or Securities.

          (iii) A Global Security will also be exchangeable if there shall have
occurred and is continuing an Event of Default or an event which, with the
giving of notice or lapse of time or both, would constitute an Event of Default
with respect to the Securities of such series represented by such Global
Security. In such event the Company will execute, and the Trustee, upon receipt
of a Company Order for the authentication and delivery of individual Securities
of such series in exchange in whole or in part for such Global Security, will
authenticate and deliver individual Securities of such series of like tenor and
terms in definitive form in an aggregate principal amount equal to the

                                      -15-
<PAGE>
 
principal amount of such Global Security or Securities representing such series
in exchange for such Global Securities or Securities.

          (iv) If specified by the Company pursuant to Section 3.01 with respect
to Securities issued or issuable in the form of a Global Security, the
Depository for such Global Security may surrender such Global Security in
exchange in whole or in part for individual Securities of such series of like
tenor and terms in definitive form on such terms as are acceptable to the
Company and such Depository. Thereupon the Company shall execute, and the
Trustee shall authenticate and deliver, without service charge, (1) to each
Person specified by such Depository a new Security or Securities of the same
series of like tenor and terms and of any authorized denominations as requested
by such Person or the Depository in aggregate principal amount equal to and in
exchange for such Person's beneficial interest in the Global Security; and (2)
to such Depository a new Global Security of like tenor and terms and in a
denomination equal to the difference, if any, between the principal amount of
the surrendered Global Security and the aggregate principal amount of Securities
delivered to Holders thereof.

          (v) Upon issuance, all Securities with identical terms and held by the
Depository on behalf of its participants will be represented by one Global
Security and be deposited with the Depository and registered in the name of a
nominee of the Depository. The Company may request the Trustee at any time to
consolidate two or more outstanding Global Securities having identical terms and
for which interest has been paid to the same date.

          (vi) In any exchange provided for in any of the preceding five
paragraphs, the Company will execute and the Trustee will authenticate and
deliver individual fully registered Securities in authorized denominations,
provided that the definitive Securities so issued in exchange for a Global
Security shall be in denominations of $100,000 and any aggregate principal
amount and tenor as the portion of such Global Security to be exchanged, and
provided further that, unless the Company agrees otherwise, Securities in
certificated registered form will be issued in exchange for a Global Security,
or any portion thereof, only if such Securities in certificated registered form
were requested by written notice to the Trustee or the Securities Registrar by
or on behalf of a person who is beneficial owner of an interest thereof given
through the Holder hereof. Except as provided above, owners of beneficial
interest in a Global Security will not be entitled to receive physical delivery
of Securities in certificated registered form and will not be considered the
Holders thereof for any purpose under the Indenture. No service charge shall be
made for any such registration of transfer or exchange, but the Company may
require payment of a sum sufficient to cover any tax or other govern-

                                      -16-
<PAGE>
 
mental charge payable in connection therewith. Upon the exchange of a Global
Security for individual Securities, such Global Security shall be cancelled by
the Trustee. Securities issued in exchange for a Global Security pursuant to
this Section 2.03 shall be registered in such names and in such authorized
denominations as the Depository for such Global Security, pursuant to the
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.

          (vii) Members in and participants of the Depository shall have no
rights under the Indenture with respect to any Global Security held on their
behalf by a Depository, and such Depository may be treated by the Company, the
trustee and any agent of the Company or the Trustee as the owner of such Global
Security for all purposes whatsoever.

          (d) Any Company Order delivered pursuant to Section 3.03 by the
Company with respect to the authentication, exchange, endorsement or delivery or
redelivery of a Global security shall be in writing, signed by any one of the
officers enumerated under the definition of "Company Order" contained in Section
1.01 or by any officer authorized by a previously delivered Company Order, but
need not comply with Section 1.02 and need not be accompanied by an Opinion of
Counsel.

          All Securities of any one series shall be substantially identical
except as to denomination and except as may otherwise be provided in or pursuant
to such Board Resolution and set forth in such Officers' Certificate or in any
such indenture supplemental hereto.  All Securities of any series need not be
issued at the same time and may be issued from time to time, consistent with the
terms of this Indenture, if so provided by or pursuant to such Board Resolution
and set forth in such Officer's Certificate or in any such indenture
supplemental hereto.

          At the option of the Company, interest on the Securities of any series
that bears interest may be paid by mailing a check to the address of the person
entitled thereto as such address shall appear in the Security Register.

          If any of the terms of the series are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such action
shall be certified by the Secretary or an Assistant Secretary of the Company and

Certificate setting forth the terms of the series.

SECTION 3.02. Denominations.

          The Securities of each series shall be issuable in registered form
without coupons in such denominations as shall be specified as contemplated by
Section 3.01.  In the absence of any such provisions with respect to the
Securities of any series, the Securities of such series shall be issuable in
denominations of $1,000 and any integral multiple thereof and shall be payable
only in Dollars.

SECTION 3.03. Execution, Authentication, Delivery and Dating.

corporate seal 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

                                      -20-
<PAGE>
 
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 and subject to the provisions hereof shall 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 2.01 and 3.01, 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 6.01) shall be fully protected in relying upon, an Opinion of Counsel
stating that:

          (1) all instruments furnished by the Company to the Trustee in
     connection with the authentication and delivery of such Securities conform
     to the requirements of this Indenture and constitute sufficient authority
     hereunder for the Trustee to authenticate and deliver such Securities;

          (2) the form of such Securities has been established in conformity
     with the provisions of this Indenture;

          (3) the terms of such Securities have been established in conformity
     with the provisions of this Indenture;

          (4) in the event that the form or terms of such Securities have been
     established in a supplemental indenture, the execution and delivery of such
     supplemental indenture have been duly authorized by all necessary
     corporate action of the Company, such supplemental indenture has been duly
     executed and delivered by the Company and, assuming due authorization,
     execution and delivery by the Trustee, is a valid and binding obligation
     enforceable against the Company in accordance with its terms, subject to
     applicable bankruptcy, insolvency and similar laws affecting creditors'
     rights generally and subject, as to enforceability, to general principles
     of equity (regardless of whether enforcement is sought in a proceeding in
     equity or at law);

                                      -21-
<PAGE>
 
          (5) the execution and delivery of such Securities have been duly
     authorized by all necessary corporate action of the Company and such
     Securities have been duly executed by the Company and, assuming due 
     authentication by the Trustee and delivery by the Company, are the valid
     and binding obligations of the Company enforceable against the Company in
     accordance with their terms, entitled to the benefit of the Indenture,
     subject to applicable bankruptcy, insolvency and similar laws affecting
     creditors' rights generally and subject, as to enforceability, to general
     principles of equity (regardless of whether enforcement is sought in a
     proceeding in equity or at law); and

          (6) the amount of Outstanding Securities of such series, together with
     the amount of such Securities, does not exceed any limit established under
     the terms of this Indenture on the amount of Securities of such series that
     may be authenticated and delivered.

          In the event that all Securities of a series are not issued at the
same time, the Trustee shall authenticate and deliver the Securities of such
series executed and delivered by the Company for original issuance upon receipt
of an order of the Company (which need not comply with Section 1.02 hereof),
signed by an officer or employee of the Company identified to the Trustee in an
Officers' Certificate, if the Trustee has previously received the Company Order
and Opinion of Counsel referred to in the third paragraph of this Section 3.03
with respect to the issuance of any Securities of such series.

          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.

          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
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.

                                      -22-
<PAGE>
 
SECTION 3.04. 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.

          If temporary Securities of any series are issued, the Company will
cause definitive Securities of that 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 for that 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 a like principal amount of
definitive Securities of the same series of 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.

SECTION 3.05. Registration, Registration of Transfer and Exchange.

          The Company or the Trustee shall keep a register (the "Security
Register") in which, subject to such reasonable regulations as the Company or
the Trustee may prescribe, the Company or the Trustee shall provide for the
registration of Securities and of transfers of Securities.

          Upon surrender for registration of transfer of any Security of any
series at the office or agency designated by the Company for that 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.

          At the option of the Holder, subject to Section 2.03, 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 such office or agency.  Whenever
any Securities are so surrendered for exchange, the Company shall execute, and

                                      -23-
<PAGE>
 
the Trustee shall authenticate and deliver, the Securities which the Holder
making the exchange is entitled to receive.

          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 or any registrar with respect to such series of
Securities, 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, but the Company or the Trustee 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 3.04, 9.06 or 11.07 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 that series selected for redemption under Section 11.03 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.

          None of the Company, the Trustee, any Paying Agent or the Securities
Registrar will have any responsibility or liability for any aspect of the
Depository's records relating to or payment made on account of beneficial
ownership interests in a Global Security or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

SECTION 3.06. Mutilated, Destroyed, Lost and Stolen Securities.

          If any mutilated Security is surrendered to the Company or 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

                                      -24-
<PAGE>
 
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 upon the Company's request the Trustee 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 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 that 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 3.07. Payment of Interest; Interest Rights Preserved.
              
          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 record date (as hereinafter defined) for such
interest notwithstanding the cancellation of such Security upon the registration
of transfer or exchange subsequent to the record date and prior to such interest
payment date; provided, however, that if and to the extent that the Company
shall default in the payment of the interest due on such interest payment date,
such defaulted interest shall be paid to the Persons in whose names outstanding
Securities are registered at the close of business on a subsequent record date
established by notice given by mail by and on behalf of the Company to the
Holders of Securities not less than fifteen days preceding such subsequent
record date, such record date to be not less than ten days preceding the date of
payment of such defaulted interest.  The term "record date" as

                                      -25-
<PAGE>
 
used in this Section 3.07 with respect to any regular interest payment date
shall mean such day preceding such interest payment date as may have been
established as the record date with respect to an interest payment date for
Securities of such series in a Board Resolution in accordance with Section 3.01
hereof.  The Company may also make payment of any defaulted interest in any
other lawful manner not inconsistent with the requirements of any securities
exchange in which the Securities 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 sentence, such manner of payment shall
be deemed practicable by the Trustee.

SECTION 3.08. 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 premium, if
any) and (subject to Section 3.07) 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 3.09. 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 cancelled by it; provided, however, that if surrendered to
any Authenticating Agent, such Securities shall be promptly cancelled by such
Authenticating Agent and forwarded to the Trustee.  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 all Securities so delivered shall be promptly cancelled by the
Trustee.  No Securities shall be authenticated in lieu of or in exchange for any
Securities cancelled as provided in this Section, except as expressly permitted
by this Indenture.  All cancelled Securities held by the Trustee shall be
disposed of as directed by a Company Order; provided that the Trustee shall not
be required to dispose of securities in a manner deemed impracticable by the
Trustee.

SECTION 3.10. Computation of Interest.
            
          Except as otherwise specified as contemplated by Section 3.01 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a year of twelve 30-day months.

SECTION 3.11. Currency of Payments in Respect of Securiies.

     (a) Except as otherwise specified pursuant to Section 3.01, payment of
the principal of (and premium, if any) and interest on Securities of any series
will be made in Dollars.

          (b) For purposes of any provision of the indenture where the Holders
of Outstanding Securities may perform an Act which requires that a specified
percentage of the Outstanding Securities of all series perform such Act and for
purposes of any decision or determination by the Trustee of amounts due and
unpaid for the principal (and premium, if any) and interest on the Securities of
all series in respect of which moneys are to be disbursed ratably, the principal
of (and premium, if any) and interest on the Outstanding Securities denominated
in a Foreign Currency will be the amount in Dollars based upon exchange rates
determined as specified pursuant to Section 3.01 for Securities of such series,
as of the date for determining whether the Holders entitled to perform such Act
have performed it, or as of the date of such decision or determination by the
Trustee, as the case may be.

          (c) Any decision or determination to be made by the Trustee regarding
exchange rates may be made instead by an agent appointed by the Trustee and
acceptable to the Company; provided that such agent shall accept such
appointment in writing and the terms of such appointment shall be acceptable to
the Company and shall, in the opinion of the Company and the Trustee at the time
of such appointment, require such agent to make such determination by a method
consistent with the method provided pursuant to Section 3.01 for the making of
such decision or determination. All decisions and determinations of the Trustee
or the agent regarding exchange rates shall be in its sole discretion and shall,
in the absence of manifest error, be conclusive for all purposes and irrevocably
binding upon the Company and all Holders of the Securities.

SECTION 3.12. Judgments.
             

          The Company may provide pursuant to Section 3.01 for Securities of any
series that the obligation, if any, of the Company to pay the principal of (and
premium, if any) and interest on the Securities of any series in a Foreign
Currency or Dollars (the "Designated Currency") as may be specified pursuant to
Section 3.01 is of the essence and thereby agree that, to the fullest extent
possible under applicable law, judgments in respect of such Securities shall be
given in the Designated Currency.  In such event, the obligation of the Company
to make payments in the Designated Currency of the principal of (and premium, if
any) and interest on such Securities shall, notwithstanding any payment in any
other Currency (whether pursuant to a judgment or otherwise), be discharged only
to the extent of the amount of the Designated Currency that the Holder receiving
such

                                      -27-
<PAGE>
 
payment may, in accordance with normal banking procedures, purchase with the sum
paid in such other Currency (after any premiums and cost of exchange) on the
Business Day in the country of issue of the Designated Currency immediately
following the day on which such Holder receives such payment.  If the amount in
the Designated Currency that may be so purchased for any reason falls short of
the amount originally due, the Company shall pay such additional amounts as may
be necessary to compensate for such shortfall, and any obligation of the Company
not discharged by such payment shall be due as a separate and independent
obligation and, until discharged as provided herein, shall continue in full
force and effect.


                                  ARTICLE IV

                          SATISFACTION AND DISCHARGE

SECTION 4.01. Satisfaction and Discharge of Indenture.

          This Indenture, with respect to the Securities of any series (if all
series issued under this Indenture are not to be affected), shall upon Company
Request cease to be of further effect (except as to any surviving rights of
registration of transfer or 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

          (1)  either

               (A) all Securities theretofore authenticated and delivered (other
          than (i) Securities which have been destroyed, lost or stolen and
          which have been replaced or paid as provided in Section 3.06 and (ii)
          Securities for whose payment money has theretofore been deposited in
          trust or segregated and held in trust by the Company and thereafter
          repaid to the Company or discharged from such trust, as provided in
          Section 10.03) have been delivered to the Trustee for cancellation; or

               (B) all such Securities not theretofore delivered to the Trustee
          for cancellation

                    (i) have become due and payable, or

                    (ii) will become due and payable at their stated maturity
               within one year, or

                    (iii) if the Securities of such series are denominated and
               payable only in Dollars (except as provided pursuant to Section
               3.01) 

                                      -28-
<PAGE>
 
               and such Securities are to be called for redemption within one
               year under arrangements satisfactory to the Trustee for the
               giving of notice of redemption by the Trustee in the name, and at
               the expense, of the Company,

          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 purpose an amount in Dollars sufficient to pay and
          discharge the entire indebtedness on such Securities not theretofore
          delivered to the Trustee for cancellation, for principal (and premium,
          if any) and interest to the date of such deposit (in the case of
          Securities which have become due and payable) or to the stated
          maturity or Redemption Date, as the case may be;

          (2) the Company has paid or caused to be paid all other sums payable
     hereunder by the Company; and

          (3) the Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that all conditions precedent
     herein provided for relating to the satisfaction and discharge of this
     Indenture have been complied with.

In the event there are Securities of two or more series hereunder, the Trustee
shall be required to execute an instrument acknowledging satisfaction and
discharge of this Indenture only if requested to do so with respect to
Securities of all series as to which it is Trustee and if the other conditions
thereto are met.  In the event there are two or more Trustees hereunder, then
the effectiveness of any such instrument shall be conditioned upon receipt of
such instruments from all Trustees hereunder.

          Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.07, the obligations of
the Trustee to any Authenticating Agent under Section 6.14 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of
this Section, the obligations of the Trustee under Section 4.02 and the last
paragraph of Section 10.03 shall survive.

SECTION 4.02.  Application of Trust Money.

          Subject to the provisions of the last paragraph of Section 10.03, all
money deposited with the Trustee pursuant to Section 4.01 shall be held in trust
and applied by it, in accordance with the provisions of the 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 Persons entitled thereto, of

                                      -29-

the principal (and premium, if any) and interest for whose payment such money
has been deposited with the Trustee.

                                   REMEDIES

     default in whose performance or whose breach is elsewhere in this Section
     5.01 specifically dealt with or which has expressly been included in this
     Indenture solely for the benefit of series of Securities other than that
     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
     25% in principal amount of the Outstanding Securities of that series a
     written notice specifying such default or breach and requiring it to be

<PAGE>
 
     an involuntary case or proceeding under any applicable Federal or State
     bankruptcy, insolvency, reorganization or other similar law now or
     hereafter in effect or (B) a decree or order adjudging the Company or any
     Significant Subsidiary a bankrupt or insolvent, or approving as properly
     filed a petition seeking reorganization, arrangement, adjustment or
     composition of or in respect of the Company or any Significant Subsidiary
     under any applicable Federal or State law, or appointing a custodian,

     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

          (6) the commencement by the Company or any Significant Subsidiary of a
     voluntary case or proceeding under any applicable Federal or State
     bankruptcy, insolvency, reorganization or other similar law now or
     hereafter in effect or of any other case or proceeding to be adjudicated a
     bankrupt or insolvent, or the consent by the Company or any Significant
     Subsidiary to the entry of a decree or order for relief in an involuntary
     case or proceeding under any applicable Federal or State bankruptcy,
     insolvency, reorganization or other similar law now or hereafter in effect
     or to the commencement of any bankruptcy or insolvency case or proceeding
     against the Company or any Significant Subsidiary, or the filing by the
     Company or any Significant Subsidiary of a petition or answer or consent
     seeking reorganization or relief under any applicable Federal or State law
     now or hereafter in effect, or the consent by the Company or any
     Significant Subsidiary to the filing of such petition or to the appointment
     of or taking possession by a custodian, receiver, liquidator, assignee,
     trustee, sequestrator or similar official of the Company or any Significant
     Subsidiary or of any substantial part of the property of the Company or any
     Significant Subsidiary, or the making by the Company or any Significant
     Subsidiary of an assignment for the benefit of creditors, or the Company or
     any Significant Subsidiary shall fail generally to pay its debts as they
     become due, or the taking of corporate action by the Company or any
     Significant Subsidiary in furtherance of any such action; or

          (7) any other Event of Default provided with respect to Securities of

                                      -31-
<PAGE>
 
          For purposes of this Section 5.01 the term "Significant Subsidiary"
shall mean any Subsidiary (i) which, as of the close of the fiscal year of the
Company immediately preceding the date of any determination hereunder,
contributed more than 7% of the consolidated gross operating revenues of the
Company and its Subsidiaries, or (ii) the Net Worth of which (determined in a
manner consistent with the manner of determining consolidated Net Worth of the
Company and its Subsidiaries) as of the close of such immediately preceding
fiscal year exceeded 7% of the consolidated Net Worth of the Company and its
Subsidiaries.

SECTION 5.02. 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, unless the
principal of all of the Securities of such series shall have already become due
and payable, the Trustee or the Holders of not less than 25% in principal amount
of the Outstanding Securities of that series may declare the principal amount
(or, in the case of certain Securities which provide for less than the entire
principal amount thereof to be due and payable upon a declaration of
acceleration of the maturity thereof pursuant to this Section 5.02, such portion
of the principal amount as may be specified in the terms of that series of
Securities) and the interest accrued thereon of all of the Securities of that
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 accrued thereon shall become
immediately due and payable.

          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 that 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 in the
     Currency in which such Securities are denominated (except as otherwise
     provided pursuant to Section 3.01) sufficient to pay

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

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

                                      -32-
<PAGE>
 
          acceleration and 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 that series,
     other than the nonpayment of the principal of Securities of that series
     which have become due solely by such declaration of acceleration, have been
     cured or waived as provided in Section 5.13.

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

          For all purposes under this Indenture, if a portion of the principal
of any Original Issue Discount Securities shall have been accelerated and
declared due and payable pursuant to the provisions hereof, then, from and after
such declaration, unless such declaration shall have been rescinded and
annulled, the principal amount of such Original Issue Discount Securities shall
be deemed, for all purposes hereunder, to be such portion of the principal
thereof as shall be due and payable as a result of such declaration; and payment
of the portion of the principal thereof as shall have become due and payable as
a result of such declaration, together with interest, if any, thereon and all
other amounts owing thereunder, shall constitute payment in full of such
Original Issue Discount Securities.

SECTION 5.03. 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

          (2) default is made in the payment of the principal of (or premium, if
     any, on) any Security when due and payable whether at its maturity or upon
     acceleration, redemption or otherwise;

                                      -33-
<PAGE>
 
          (3) default is made in the deposit of any sinking fund payment when
     and as due by the terms of any Security,

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 premium, if any) and interest, interest on any
overdue principal (and premium, if any) and, to the extent that payment of such
interest shall be legally enforceable, interest 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 the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon such Securities, wherever
situated.

          If an Event of Default with respect to 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 5.04. Trustee May File Proofs of Claim.

          In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
similar judicial proceeding relative to the Company, or any other obligor upon
the Securities or the property of the Company, or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal or interest) shall be entitled
and empowered, by intervention in such proceeding or otherwise:

          (1) to file and prove a claim for the whole amount of principal (and
     premium, if any) and interest owing and unpaid in respect of the Securities
     and to

                                      -34-
<PAGE>
 
     file such other papers or documents as may be necessary or advisable in
     order to have the claims of the Trustee (including any claim for the
     reasonable compensation, expenses, disbursements and advances of the
     Trustee, its agents and counsel) and of the Holders allowed in such
     judicial proceeding, and

          (2) 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 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 the 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 6.07.

          Subject to the provisions of Article Eight of this Indenture, nothing
herein contained 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
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

SECTION 5.05. 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.

          In any proceeding brought by the Trustee (and also in any proceeding
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party), the Trustee shall be held to represent all the
Holders of the Securities in respect to which action was taken, and it shall not
be necessary to make any Holders of such Securities parties to any such
proceedings.

                                      -35-

SECTION 5.06. 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 premium,
if any) or interest, upon presentation of the Securities 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
     6.07;

          SECOND: To the payment of the amounts then due and unpaid for
     principal of (and premium, if any) 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 premium, if
     any) and interest respectively; and

          THIRD: To the Company.

SECTION 5.07. 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 custodian, liquidator, assignee, sequestrator,
receiver, trustee, or other similar official, 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 that
     series;

          (2) the Holders of not less than 25% in principal amount of the
     Outstanding Securities of that 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

                                      -36-

<PAGE>
 
          (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 that series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other such
Holder or Holders of any other series, or to obtain or to seek to obtain
priority or preference over any other 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 such Holders.

SECTION 5.08. 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 premium, if any) and (subject to
Section 3.07) interest on such Security on the due dates 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 5.09. 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 of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

SECTION 5.10. Rights and Remedies Cumulative.

          Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in the last paragraph
of Section 3.06, 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 5.11. Delay or Omission Not Waiver.

          No delay or omission of the Trustee or of any Holder of any Securities
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
an acquiescence therein. Every right and remedy given by this Article or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

SECTION 5.12. 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 shall have determined that the action so directed
     would not be unjustly prejudicial to the Holders of any Securities of any
     series with respect to which the Trustee is the Trustee not taking part in
     such direction,

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

          (4) the Trustee shall be indemnified as hereinafter provided.

SECTION 5.13. Waiver of Past Defaults.

          Subject to Section 5.02, 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 past default
hereunder with respect to such series and its consequences, except a default

          (1) in the payment of the principal of (or premium, if any) 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.

                                      -38-

<PAGE>
 
          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 5.14. Undertaking for Costs.

          All parties to this Indenture agree, and each Holder of any Security
by his acceptance thereof shall be deemed to have agreed, that any court may in
its discretion require, 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, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than 10% in principal amount of the Outstanding Securities of
any series, or to any suit instituted by any Holder for the enforcement of the
payment of the principal of (or premium, if any) or interest on any Security on
or after the due dates expressed in such Security (or, in the case of
redemption, on or after the Redemption Date).

SECTION 5.15. 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 that it will not hinder, delay or impede the exercise of any power
herein granted to the Trustee, but will suffer and permit the exercise of every
such power as though no such law had been enacted.

SECTION 5.16. Duty to Accelerate.

          The Trustee shall be under no duty to accelerate the debt hereunder or
to institute any proceedings unless it knows or in the exercise of reasonable
diligence should have known of the existence of an event of default hereunder.

                                  THE TRUSTEE

SECTION 6.01. Certain Duties and Responsibilities.

          (a) Except during the continuance of an Event of Default with respect
to Securities of any series,

          (1) the Trustee undertakes to perform, with respect to Securities of
     such series, such duties and only such duties as are specifically set forth
     in this Indenture, and no implied covenants or obligations shall be read
     into this Indenture against the Trustee; and

          (2) in the absence of bad faith on its part, the Trustee may, with
     respect to Securities of such series, conclusively rely, as to the truth of
     the statements and the correctness of the opinions expressed therein, upon
     certificates or opinions furnished to the Trustee and conforming to the
     requirements of this Indenture; but in the case of any such certificates or
     opinions which by any provisions hereof are specifically required to be
     furnished to the Trustee, the Trustee shall be under a duty to examine the
     same to determine whether or not they conform to the requirements of this
     Indenture.

          (b) In case an Event of Default with respect to Securities of any
series has occurred and is continuing, the Trustee shall exercise, with respect
to Securities of such series, such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

          (c) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that

          (1) this Subsection shall not be construed to limit the effect of
     Subsection (a) of this Section;

          (2) the Trustee shall not be liable for any error of judgment made in
     good faith by a Responsible Officer, unless it shall be proved that the
     Trustee was negligent in ascertaining the pertinent facts;

                                      -40-
<PAGE>
 
          (3) the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with the direction
     of the Holders of a majority in principal amount of the Outstanding
     Securities of any series pursuant to the provisions of Section 5.12
     relating to the time, method and place of conducting any proceeding for any
     remedy available to the Trustee, or exercising any trust or power conferred
     upon the Trustee, under this Indenture with respect to the Securities of
     such series; and

          (4) no provision of this 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.

          (d) 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 6.02. Notice of Defaults.

          Within 90 days after the occurrence of any default hereunder with
respect to the Securities of any series, the Trustee shall transmit by mail to
all Holders of Securities of such series, as their names and addresses appear in
the Security Register, notice of such default hereunder known to the Trustee,
unless such default shall have been cured or waived; provided, however, that,
except in the case of a default in the payment of the principal of (or premium,
if any) or interest on any Security of such series or in the payment of any
sinking fund installment with respect to Securities of such series, the Trustee
shall be protected in withholding such notice if and so long as the board of
directors, the executive committee or a trust committee of directors or
Responsible Officers of the Trustee in good faith determine that the withholding
of such notice is in the interest of the Holders of Securities of such series;
and provided, further, that in the case of any default of the character
specified in Section 5.01(4) with respect to the 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.

     instrument, opinion, report, notice, request, direction, consent, order,

     deem it desirable that a matter be proved or established prior to taking,
     suffering or omitting any action hereunder, the Trustee (unless other
     evidence be herein specifically prescribed) may, in the absence of bad
     faith on its part, rely upon an Officers' Certificate;

          (4) the Trustee may consult with counsel and the written advice of
     such counsel or any Opinion of Counsel shall be full and complete
     authorization and protection in respect of any action taken, suffered or
     omitted by it hereunder in good faith and in reliance thereon;

          (5) the Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request or direction
     of any of the Holders pursuant to this Indenture, unless such Holders shall
     have offered to the Trustee reasonable security or indemnity against the
     costs, expenses and liabilities which might be incurred by it in compliance
     with such request or direction;

          (6) the Trustee shall not be bound to make any investigation into the

     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, other evidence of indebtedness or other paper or
     document, but the Trustee, in its discretion, may make such further inquiry
     or investigation into such matters of fact as it may see fit, and, if the
     Trustee shall determine to

                                      -42-
<PAGE>
 
     make such further inquiry or investigation, it shall be entitled to examine

     attorney; and

     negligence on the part of any agent or attorney appointed with due care by
     it hereunder.

SECTION 6.04. Not Responsible for Recitals or Issuance of Securities.

          The recitals contained herein and in the Securities, except the
Trustee's certificate 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 to the validity
or sufficiency of this Indenture or of the Securities. The Trustee or any
Authenticating Agent shall not be accountable for the use or application by the
Company of Securities or the proceeds thereof.

SECTION 6.05. May Hold Securities.

          The Trustee, any Authenticating Agent, any Paying Agent 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 6.08 and 6.13, may
otherwise deal with the Company with the same rights it would have if it were
not Trustee, Authenticating Agent, Paying Agent or such agent.

SECTION 6.06. Money Held in Trust.

          Money held by the Trustee in trust hereunder need not be segregated

     trustee of an express trust);

          (2) except as otherwise expressly provided herein, to reimburse the
     Trustee in Dollars upon its

                                      -43-
<PAGE>
 
     request for all reasonable expenses, disbursements and advances incurred or
     made by the Trustee in accordance with any provision of this Indenture
     (including the reasonable compensation and the expenses and disbursements

     advance as may be attributable to its negligence or bad faith; and

          (3) to indemnify the Trustee for, and to hold it harmless against, any
     loss, liability or expense incurred without negligence or bad faith on its
     part, arising out of or in connection with the acceptance or administration

     exercise or performance of any of its powers or duties hereunder.

SECTION 6.08. Disqualification; Conflicting Interests.

          (a) If the Trustee has or shall acquire any conflicting interest, as
defined in this Section, with respect to the Securities of any series, it shall,
within 90 days after ascertaining that it has such conflicting interest, either
eliminate such conflicting interest or resign with respect to the Securities of
that series in the manner and with the effect hereinafter specified in this
Article.

          (b) In the event that the Trustee shall fail to comply with the
provisions of Subsection (a) of this Section with respect to the Securities of
any series, the Trustee shall, within 10 days after the expiration of such 90-
day period, transmit by mail to all Holders of Securities of, that series, as
their names and addresses appear in the Security Register, notice of such
failure.

          (c) For the purposes of this Section, the Trustee shall be deemed to
have a conflicting interest with respect to the Securities of any series if:

          (1) the Trustee is trustee under this Indenture with respect to the
     Outstanding Securities of any series other than that series or is trustee
     under another indenture under which any other securities, or certificates
     of interest or participation in any other securities, of the Company are
     outstanding, unless such other indenture is a collateral trust indenture
     under which the only collateral consists of Securities issued under this
     Indenture, provided that there shall be excluded from the operation of this
     paragraph this Indenture with respect to the Securities of any series other
     than that series or other indenture or indentures under which other
     securities, or certificates of

                                      -44-
<PAGE>
 
     interest or participation in other securities, of the Company are
     outstanding, if

               (i) this Indenture and such other indenture or indentures are
          wholly unsecured and such other indenture or indentures are hereafter
          qualified under the Trust Indenture Act, unless the Commission shall
          have found and declared by order pursuant to Section 305(b) or Section
          307(c) of this Trust Indenture Act that differences exist between the
          provisions of this Indenture with respect to Securities of that series
          and one or more other series or the provisions of such other indenture
          or indentures (or any series of securities issuable thereunder) which
          are so likely to involve a material conflict of interest as to make it
          necessary in the public interest or for the protection of investors to
          disqualify the Trustee from acting as such under this Indenture with
          respect to the Securities of that series and such other series or
          under such other indenture or indentures, or

               (ii) the Company shall have sustained the burden of proving, on
          application to the Commission and after opportunity for hearing
          thereon, that trusteeship under this Indenture with respect to the
          Securities of that series and such other series or such other
          indenture or indentures is not so likely to involve a material
          conflict of interest as to make it necessary in the public interest or
          for the protection of investors to disqualify the Trustee from acting
          as such under this Indenture with respect to the Securities of that
          series and such other series or under such other indenture or
          indentures;

          (2) the Trustee or any of its directors or executive officers is an
     obligor upon the Securities or an underwriter for the Company;

          (3) the Trustee directly or indirectly controls, is directly or
     indirectly controlled by, or is under direct or indirect common control
     with the Company or an underwriter for the Company;

          (4) the Trustee or any of its directors or executive officers is a
     director, officer, partner, employee, appointee or representative of the
     Company, or of an underwriter (other than the Trustee itself) for the
     Company who is currently engaged in the busi ness of underwriting, except
     that (i) one individual may be a director or an executive officer, or both,
     of

                                      -45-
<PAGE>
 
     the Trustee and a director or an executive officer, or both, of the Company
     but may not be at the same time an executive officer of both the Trustee
     and the Company; (ii) if and so long as the number of directors of the
     Trustee in office is more than nine, one additional individual may be a
     director or an executive officer, or both, of the Trustee and a director of
     the Company; and (iii) the Trustee may be designated by the Company or by
     any underwriter for the Company to act in the capacity of transfer agent,
     registrar, custodian, paying agent, fiscal agent, escrow agent or
     depositary, or in any other similar capacity, or, subject to the provisions
     of paragraph (1) of this Subsection, to act as trustee, whether under an
     indenture or otherwise;

          (5) 10% or more of the voting securities of the Trustee is
     beneficially owned either by the Company or by any director, partner or
     executive officer thereof, or 20% or more of such voting securities is
     beneficially owned, collectively, by any two or more of such persons; or
     10% or more of the voting securities of the Trustee is beneficially owned
     either by an underwriter for the Company or by any director, partner or
     executive officer thereof, or is beneficially owned, collectively, by any
     two or more such persons;

          (6) the Trustee is the beneficial owner of, or holds a collateral
     security for an obligation which is in default (as hereinafter in this
     Subsection defined), (i) 5% or more of the voting securities, or 10% or
     more of any other class of security, of the Company not including the
     Securities issued under this Indenture and securities issued under any
     other indenture under which the Trustee is also trustee, or (ii) 10% or
     more of any class of security of an underwriter for the Company;

          (7) the Trustee is the beneficial owner of, or holds as collateral
     security for an obligation which is in default (as hereinafter in this
     Subsection defined) 5% or more of the voting securities of any person who,
     to the knowledge of the Trustee, owns 10% or more of the voting securities
     of, or controls directly or indirectly or is under direct or indirect
     common control with, the Company;

          (8) the Trustee is the beneficial owner of, or holds as collateral
     security for an obligation which is in default (as hereinafter in this
     Subsection defined), 10% or more of any class of security of any person
     who, to the knowledge of the Trustee, owns 50% or more of the voting
     securities of the Company; or

                                      -46-
<PAGE>
 
          (9) the Trustee owns, on the date of default upon the Securities of
     such series or any anniversary of such default while such default shall be
     continuing, in the capacity of executor, administrator, testamentary or
     inter vivos trustee, guardian, committee or conservator, or in any other
     similar capacity, an aggregate of 25% or more of the voting securities, or
     of any class of security, of any person, the beneficial ownership of a
     specified percentage of which would have constituted a conflicting interest
     under paragraph (6), (7) or (8) of this Subsection.  As to any such
     securities of which the Trustee acquired ownership through becoming
     executor, administrator or testamentary trustee of an estate which
     included them, the provisions of the preceding sentence shall not apply,
     for a period of two years from the date of such acquisition, to the extent
     that such securities included in such estate do not exceed 25% of such
     voting securities or 25% of any such class of security. Promptly after the
     date of such default upon the Securities of such series and annually in
     each succeeding year that the Securities of such series remain in default,
     the Trustee shall make a check of its holdings of such securities in any of
     the above-mentioned capacities as of such May 15.  If the Company fails to
     make payment in full of the principal of (or premium, if any) or interest
     on any of the Securities when as the same becomes due and payable, and such
     failure continues for 30 days thereafter, the Trustee shall make a prompt
     check of its holdings of such securities in any of the above mentioned
     capacities as of the date of the expiration of such 30-day period, and
     after such date, notwithstanding the foregoing provisions of this
     paragraph, all such securities so held by the Trustee, with sole or joint
     control over such securities vested in it, shall, but only so long as such
     failure shall continue, be considered as though beneficially owned by the
     Trustee for the purposes of paragraphs (6), (7) and (8) of this Subsection.

          (10) except under the circumstances described in paragraphs (1), (3),
     (4), (5) and (6) of Section 6.13(b), the Trustee shall be or shall become a
     creditor of the Company.

          The specification of percentages in paragraphs (5) to (9), inclusive,
of this Subsection shall not be construed as indicating that the ownership of
such percentages of the securities of a person is or is not necessary or
sufficient to constitute direct or indirect control for the purposes of
paragraph (3) or (7) of this Subsection.

                                      -47-

          For the purposes of paragraph (1) of this Subsection, Sections 5.12
and 5.13 and the definition of the term "Outstanding," the term "series of
securities" or "series" means a series, class or group of securities issuable
under an indenture pursuant to whose terms holders of one such series may vote
to direct the indenture trustee, or otherwise take action pursuant to a vote of
such holders, separately from holders of another such series, provided that
"series of securities" or "series" shall not include any series of securities
issuable under an indenture if all such series rank equally and are wholly

          For the purposes of paragraphs (6), (7), (8) and (9) of this
Subsection only, (i) the terms "security" and "securities" shall include only

include any note or other evidence of indebtedness issued to evidence an
obligation to repay moneys lent to a person by one or more banks, trust
companies or banking firms, or any certificate of interest or participation in

be deemed to be the owner or holder of (A) any security which it holds as
collateral security, as trustee or otherwise, for an obligation which is not in
default as defined in Clause (ii) above, or (B) any security which it holds as
collateral security under this Indenture, irrespective of any default hereunder,
or (C) any security which it holds as agent for collection, or as custodian,
escrow agent or depositary, or in any similar representative capacity.

          (1) The term "underwriter," when used with reference to the Company,
     means every person who, within three years prior to the time as of which
     the determination is made, has purchased from the Company with a view to,

     participated or has had a direct or indirect participation in any such
     undertaking, or has participated or has had a participation in the direct
     or indirect underwriting of any such undertaking, but such term shall not
     include a person whose interest was limited to a commission from an

     partnership, an association, a joint-stock company, a trust, an
     unincorporated organization or a government or political subdivision
     thereof. As used in this paragraph, the term "trust" shall include only a

     are evidenced by a security.

          (4) The term "voting security" means any security presently entitling
     the owner or holder thereof to vote in the direction or management of the
     affairs of a person, or any security issued under or pursuant to any trust,

          (7) The term "default" shall mean, with respect to the Securities of
     any series, an Event of Default in respect thereof (exclusive of any period

          (e) Except in the case of a default in the payment of the principal of
(and premium, if any) or interest on the Securities of any series, or in the
payment of any sinking fund or analogous payment, the Trustee shall not be
required to resign as provided by this Section if the Trustee shall have
sustained the burden of proving, on application to the Commission and after
opportunity for hearing thereon, that:

          (1) the default under this Indenture may be cured or waived during a
     reasonable period and under the procedures described in such application,
     and

          (2) a stay of the Trustee's duty to resign will not be inconsistent
     with the interests of the Holders of the Securities of the applicable
     series.

          The filing of such an application shall automatically stay the
performance of the duty to resign until the Commission orders otherwise.

          (f) The percentages of voting securities and other securities

          (1) A specified percentage of voting securities of the Trustee, the
     Company or any other person referred to in this Section (each of whom is
     referred to as a "person" in this paragraph) means such amount of the
     outstanding voting securities of such person as entitles the holder or
     holders thereof to cast such specified percentage of the aggregate votes
     which the holders of all the outstanding voting securities of such person
     are entitled to cast in the direction or management of the affairs of such
     person.

          (2) A specified percentage of a class of securities of a person means
     such percentage of the aggregate amount of securities of the class
     outstanding.

          (3) The term "amount," when used in regard to securities, means the
     principal amount if relating to evidences of indebtedness, the number of
     shares if relating to capital shares and the number of units if relating to
     any other kind of security.

          (4) The term "outstanding" means those securities issued and not held
     by or for the account of the issuer. The following securities shall not be
     deemed outstanding within the meaning of this definition:

               (i) securities of an issuer held in a sinking fund relating to
          securities of the issuer of the same class;

               (ii) securities of an issuer held in a sinking fund relating to
          another class of securities of the issuer, if the obligation evidenced

          interest or otherwise;

               (iii) securities pledged by the issuer thereof as security for an

               (iv) securities held in escrow if placed in escrow by the issuer
          thereof;

     provided, however, that any voting securities of an issuer shall be deemed
     outstanding if any person other than the issuer is entitled to exercise the
     voting rights thereof.

                                      -50-
<PAGE>
 
          (5) A security shall be deemed to be of the same class as another
     security if both securities confer upon the holder or holders thereof
     substantially the same right and privileges; provided, however, that, in
     the case of secured evidences of Indebtedness, all of which are issued
     under a single indenture, differences in the interest rates or maturity
     dates of various series thereof shall not be deemed sufficient to
     constitute such series' different classes and provided, further, that, in
     the case of unsecured evidences of indebtedness, differences in the
     interest rates or maturity dates thereof shall not be deemed sufficient to
     constitute them securities of different classes, whether or not they are
     issued under a single indenture.

SECTION 6.09. Corporate Trustee Required; Eligibility.

          There shall at all times be a Trustee hereunder with respect to each
series of Securities which shall be either (i) a corporation, bank or trust
company 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 exercise corporate trust powers and subject to supervision or
examination by United States or Federal or State authority or (ii) a corporation
or other Person organized and doing business under the laws of any other
government which is permitted to act as Trustee pursuant to any rule, regulation
or order of the Commission, authorized under such laws to exercise corporate
trust powers and subject to supervision or examination by an authority of such
government, or a political subdivision thereof, substantially equivalent to the
supervision or examination applicable to the institution described in clause (i)
above, in each case having a combined capital and surplus of at least
$50,000,000 and its Corporate Trust Office in Chicago, Illinois or New York, New
York, if there shall be such a corporation or Person in such location willing to
act upon or customary and reasonable terms. If such corporation or other Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes
of this Section, the combined capital and surplus of such corporation or other
Person shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. Neither the Company nor any
Person directly or indirectly controlling, controlled by or under common control
with the Company shall serve as Trustee. If at any time the Trustee shall cease
to be eligible in accordance with the provisions of this Section 6.09, it shall
resign immediately in the manner and with the effect hereinafter specified in
this Article.

SECTION 6.10. Resignation and Removal; Appointment of Successor.

          (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 6.11.

          (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 Trustee required by Section 6.11 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to such
series.

          (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 6.08(a) after
     written request therefor by the Company or by any Holder who has been a
     bona fide Holder of a Security of the series as to which the Trustee has a
     conflicting interest for at least six months, or

          (2) the Trustee shall cease to be eligible under Section 6.09 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 5.14, 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 with respect to all
Securities and the appointment of a successor Trustee or Trustees.

                                      -52-

<PAGE>
 
          (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 that or those 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 shall comply with the
applicable requirements of Section 6.11. 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 accordance with the applicable requirements of Section
6.11, become the successor 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 of Securities of such series and
accepted appointment in the manner required by Section 6.11, 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
of a successor Trustee with respect to the Securities of any series by mailing
written notice of such event by first-class mail, postage prepaid, to all
Holders of Securities of such series as their names and addresses appear in the
Security Register. Each notice shall include the name of the successor Trustee
with respect to the Securities of such series and the address of its Corporate
Trust Office.

SECTION 6.11. 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,

                                      -53-
<PAGE>
 
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 and money held by such retiring Trustee hereunder.

          (b) In case of the appointment hereunder of a successor 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 that
or those series to which the appointment of such successor Trustee 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 that or those 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, 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 that no Trustee shall be responsible for any act or
failure to act on the part of any other Trustee hereunder; 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,
such retiring Trustee shall with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates have no
further responsibility for the exercise of rights and powers or for the
performance of the duties and obligations vested in the Trustee under this
Indenture, 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 that or those 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, to the extent contemplated by
such supplemental indenture, the property and money held by such retiring
Trustee hereunder with respect to the Securities of that or those series to
which the appointment of such successor Trustee relates.

                                      -54-

<PAGE>
 
     (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 6.12. 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 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 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 6.13. Preferential Collection of Claims Against Company.

     (a) Subject to Subsection (b) of this Section, if the Trustee shall be or
shall become a creditor, directly or indirectly, secured or unsecured, of the
Company within four months prior to a default, as defined in Subsection (c) of
this Section, or subsequent to such a default, then, unless and until such
default shall be cured, the Trustee shall set apart and hold in special account
for the benefit of the Trustee individually, the Holders of the Securities and
the holders of other indenture securities, as defined in Subsection (c) of this
Section:

          (1) an amount equal to any and all reductions in the amount due and
     owing upon any claim as such creditor in respect of principal, premium, if
     any, or interest, effected after the beginning of such four months' period
     and valid as against the Company and its other creditors, except any such
     reduction resulting from the receipt or disposition of any property
     described in paragraph (2) of this Subsection, or from the exercise of any
     right of set-off which the Trustee could have exercised if a petition in
     bankruptcy had been filed by or against the Company upon the date of such
     default; and

                                     -55-

<PAGE>
 
          (2) all property received by the Trustee in respect of any claims as
     such creditor, either as security therefor, or in satisfaction or
     composition thereof, or otherwise, after the beginning of such four months'
     period, or an amount equal to the proceeds from the disposition of any such
     property, if disposed of, subject, however, to the rights, if any, of the
     Company and its creditors in such property or such proceeds.

Nothing herein contained, however, shall affect the right of the Trustee:

          (A) to retain for its own account (i) payments made on account of any
     such claim by any Person (other than the Company) who is liable thereon,
     and (ii) the proceeds of the bona fide sale of any such claim by the
     Trustee to a third Person, and (iii) distributions made in cash, securities
     or other property in respect of claims filed against the Company in
     bankruptcy or receivership or in proceedings for reorganization pursuant to
     the Federal Bankruptcy Act or applicable State law;

          (B) to realize, for its own account, upon any property held by it as
     security for any such claim, if such property was so held prior to the
     beginning of such four months' period;

          (C) to realize, for its own account, but only to the extent of the
     claim hereinafter mentioned, upon any property held by it as security for
     any such claim, if such claim was created after the beginning of such four
     months' period and such property was received as security therefor
     simultaneously with the creation thereof, and if the Trustee shall sustain
     the burden of proving that at the time such property was so received the
     Trustee had no reasonable cause to believe that a default, as defined in
     Subsection (c) of this Section, would occur within four months; or

          (D) to receive payment on any claim referred to in paragraph (B) or
     (C), against the release of any property held as security for such claim as
     provided in paragraph (B) or (C), as the case may be, to the extent of the
     fair value of such property.

          For the purposes of paragraphs (B), (C) and (D), property substituted
after the beginning of such four months' period for property held as security at
the time of such substitution shall, to the extent of the fair value of the
property released, have the same status as the property released, and, to the
extent that any claim referred to in any of such paragraphs is created in
renewal of or in substitution for or for the

                                      -56-
<PAGE>
 
purpose of repaying or refunding any pre-existing claim of the Trustee as such
creditor, such claim shall have the same status as such preexisting claim.

          If the Trustee shall be required to account, the funds and property
held in such special account and the proceeds thereof shall be apportioned among
the Trustee, the Holders and the holders of other indenture securities in such
manner that the Trustee, the Holders and the holders of other indenture
securities realize, as a result of payments from such special account and
payments of dividends on claims filed against the Company in bankruptcy or
receivership or in proceedings for reorganization pursuant to the Federal
Bankruptcy Act or applicable State law, the same percentage of their respective
claims, figured before crediting to the claim of the Trustee anything on account
of the receipt by it from the Company of the funds and property in such special
account and before crediting to the respective claims of the Trustee and the
Holders and the holders of other indenture securities dividends on claims filed
against the Company in bankruptcy or receivership or in proceedings for
reorganization pursuant to the Federal Bankruptcy Act or applicable State law,
but after crediting thereon receipts on account of the indebtedness represented
by their respective claims from all sources other than from such dividends and
from the funds and property so held in such special account.  As used in this
paragraph, with respect to any claim, the term "dividends" shall include any
distribution with respect to such claim, in bankruptcy or receivership or
proceedings for reorganization pursuant to the Federal Bankruptcy Act or
applicable State law, whether such distribution is made in cash, securities or
other property, but shall not include any such distribution with respect to the
secured portion, if any, of such claim.  The court in which such bankruptcy,
receivership or proceeding for reorganization is pending shall have jurisdiction
(i) to apportion among the Trustee, the Holders and the holders of other
indenture securities, in accordance with the provisions of this paragraph, the
funds and property held in such special account and proceeds thereof, or (ii) in
lieu of such apportionment, in whole or in part, to give to the provisions of
this paragraph due consideration in determining the fairness of the
distributions to be made to the Trustee and the Holders and the holders of other
indenture securities with respect to their respective claims, in which event it
shall not be necessary to liquidate or to appraise the value of any securities
or other property held in such special account or as security for any such
claim, or to make a specific allocation of such distributions as between the
secured and unsecured portions of such claims, or otherwise to apply the
provisions of this paragraph as a mathematical formula.

          Any Trustee which has resigned or been removed after the beginning of
such four months' period shall be subject to the provisions of this Subsection
as though such resignation or removal had not occurred.  If any Trustee has
resigned or been

                                      -57-
<PAGE>
 
removed prior to the beginning of such four months' period, it shall be subject
to the provisions of this Subsection if and only if the following conditions
exist:

          (i) the receipt of property or reduction of claim, which would have
     given rise to the obligation to account, if such Trustee had continued as
     Trustee, occurred after the beginning of such four months' period; and

          (ii) such receipt of property or reduction of claim occurred within
     four months after such resignation or removal.

          In any case commenced under the Bankruptcy Act of July 1, 1898, or any
amendment thereto enacted prior to November 6, 1978, all references above to
periods of three months shall be deemed to be references to periods of four
months.

          (b) There shall be excluded from the operation of Subsection (a) of
this Section a creditor relationship arising from:

          (1) the ownership or acquisition of securities issued under any
     indenture, or any security or securities having a maturity of one year or
     more at the time of acquisition by the Trustee;

          (2) advances authorized by a receivership or bankruptcy court of
     competent jurisdiction or by this Indenture, for the purpose of preserving
     any property which shall at any time be subject to the lien of this
     Indenture or of discharging tax liens or other prior liens or encumbrances
     thereon, if notice of such advances and of the circumstances surrounding
     the making thereof is given to the Holders at the time and in the manner
     provided in this Indenture;

          (3) disbursements made in the ordinary course of business in the
     capacity of trustee under an indenture, transfer agent, registrar,
     custodian, paying agent, fiscal agent or depositary, or other similar
     capacity;

          (4) an indebtedness created as a result of services rendered or
     premises rented; or an indebtedness created as a result of goods or
     securities sold in a cash transaction, as defined in Subsection (c) of this
     Section;

          (5) the ownership of stock or of other securities of a corporation
     organized under the provisions of Section 25(a) of the Federal Reserve Act,
     as amended,

                                      -58-
<PAGE>
 
     which is directly or indirectly a creditor of the Company; and

          (6) the acquisition, ownership, acceptance or negotiation of any
     drafts, bills of exchange, acceptances or obligations which fall within
     the classification of self-liquidating paper, as defined in Subsection (c)
     in this Section.

          (c) For the purposes of this Section 6.13 only:

          (1) the term "default" means any failure to make payment in full of
     the principal of or interest on any of the Securities or upon the other
     indenture securities when and as such principal or interest becomes due
     and payable;

          (2) the term "other indenture securities" means securities upon which
     the Company is an obligor outstanding under any other indenture (i) under
     which indenture and as to which securities the Trustee is also trustee,
     (ii) which contains provisions substantially similar to the provisions of
     this Section, and (iii) under which a default exists at the time of the
     apportionment of the funds and property held in such special account;

          (3) the term "cash transaction" means any transaction in which full
     payment for goods or securities sold is made within seven days after

SECTION 6.14. Appointment of Authenticating Agent.

          At any time when any of the Securities remain Outstanding 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 exchange, registration of
transfer or partial redemption thereof or pursuant to Section 3.06 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. Whenever 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 by an Authenticating Agent and a certificate of
authentication executed by an Authenticating Agent.  Each 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 not less than
$50,000,000 and subject to supervision or examination by Federal or State
authority.  If such Authenticating Agent publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section 6.14, the combined
capital and surplus of such Authenticating Agent 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
in accordance with the provisions of this Section 6.14, such Authenticating
Agent shall resign immediately in the manner and with the effect specified in
this Section 6.14.

          Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section 6.14, without the execution or filing of any paper or any
further act on the part of the Trustee or Authenticating Agent.

          An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company.  The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent and to the Company.  Upon receiving such a
notice

                                      -60-
<PAGE>
 
of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible 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 written notice of
such appointment by first-class mail, postage prepaid, to all Holders of
Securities of the series with respect to which such Authenticating Agent will
serve, as their names and addresses appear in the Security Register.  Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section 6.14.

          The Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section 6.14, and the
Trustee shall be entitled to be reimbursed for such payments.

          The provisions of Sections 3.08, 6.04 and 6.05 shall be applicable to
each Authenticating Agent.

          Pursuant to each appointment made under this Section 6.14, the
Securities of each series covered by such appointment may have endorsed thereon,
in addition to the Trustee's certificate 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.

               HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

SECTION 7.01. Company to Furnish Trustee Names and Addresses of Holders.

          The Company will furnish or cause to be furnished to the Trustee

                                      -61-
<PAGE>
 
          (1) semi-annually, not more than 15 days after each record date with
     respect to a regular interest payment date for each series of Securities, a
     list, in such form as the Trustee may reasonably require, containing all
     the information in the possession and control of the Company or of its
     paying agents regarding the names and addresses of the Holders of such
     series as of such record date; provided, however, that if Securities of any
     series shall have more than two regular interest payment dates in each
     calendar year or shall not bear interest, then such list with respect to
     such series of Securities will be furnished to the Trustee semi-annually on
     such dates as may be agreeable to the Trustee; and

          (2) at such other times as the Trustee may request in writing, within
     30 days after the receipt by the Company of any such request, a list of
     similar form and content as of a date not more than 15 days prior to the
     time such list is furnished;

except that if the Trustee is the sole registrar with respect to any series of
Securities, no such list need be furnished with respect to such series.

SECTION 7.02. Preservation of Information; Communications to Holders.

          (a) The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders contained in the most recent
list furnished to the Trustee as provided in Section 7.01 and the names and
addresses of Holders received by the Trustee in its capacity as sole Security
Registrar, if so acting.  The Trustee may destroy any list furnished to it as
provided in Section 7.01 upon receipt of a new list so furnished.

          (b) If three or more Holders (herein referred to as "applicants")
apply in writing to the Trustee, and furnish to the Trustee reasonable proof
that each such applicant has owned a Security for a period of at least six
months preceding the date of such application, and such application states that
the applicants desire to communicate with other Holders with respect to their
rights under this Indenture or under the Securities and is accompanied by a copy
of the form of proxy or other communication which such applicants propose to
transmit, then the Trustee shall, within five business days after the receipt of
such application, at its election, either

          (1) afford such applicants access to the information preserved at the
     time by the Trustee in accordance with Section 7.02(a), or

                                      -62-
<PAGE>
 
          (2) inform such applicants as to the approximate number of Holders
     whose names and addresses appear in the information preserved at the time
     by the Trustee in accordance with Section 7.02(a), and as to the
     approximate cost of mailing to such Holders the form of proxy or other
     communication, if any, specified in such application.

          If the Trustee shall elect not to afford such applicants access to
such information, the Trustee shall, upon the written request of such
applicants, mail to each Holder whose name and address appears in the
information preserved at the time by the Trustee in accordance with Section
7.02(a) a copy of the form of proxy or other communication which is specified in
such request, with reasonable promptness after a tender to the Trustee of the
material to be mailed and of payment, or provision for the payment, of the
reasonable expenses of mailing, unless within five days after such tender the
Trustee shall mail to such applicants and file with the Commission, together
with a copy of the material to be mailed, a written statement to the effect
that, in the opinion of the Trustee, such mailing would be contrary to the best
interest of the Holders or would be in violation of applicable law. Such written
statement shall specify the basis of such opinion. If the Commission, after
opportunity for a hearing upon the objections specified in the written statement
so filed, shall enter an order refusing to sustain any of such objections or if,
after the entry of an order sustaining one or more of such objections, the
Commission shall find, after notice and opportunity for hearing, that all the
objections so sustained have been met and shall enter an order so declaring, the
Trustee shall mail copies of such material to all such Holders with reasonable
promptness after the entry of such order and the renewal of such tender;
otherwise the Trustee shall be relieved of any obligation or duty to such
applicants respecting their application.

          (c) Every Holder of Securities, by receiving and holding the same,
agrees with the Company and the Trustee that neither the Company nor the Trustee
nor any agent of either of them shall be held accountable by reason of the
disclosure of any such information as to the names and addresses of the Holders
in accordance with Section 7.02(b), regardless of the source from which such
information was derived, and that the Trustee shall not be held accountable by
reason of mailing any material pursuant to a request made under Section 7.02(b).

SECTION 7.03. Reports by Trustee.

          (a) Within 60 days after May 15 of each year commencing with the year

     prior to that of the Securities, on the trust estate or on any property or

     remaining unpaid aggregate not more than 1/2 of 1% of the principal amount
     of the Securities Outstanding on the date of such report;

     security therefor, except an indebtedness based upon a creditor
     relationship arising in any manner described in Section 6.13(b)(2), (3),

     hereunder which it has not previously reported and which in its opinion
     materially affects the Securities, or the Securities of any series, except

     declaration of acceleration of the maturity thereof), or impair the right
     to institute suit for the enforcement of any such payment on or after the
     due date thereof (or, in the case of redemption, on or after the Redemption

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

          The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of (and premium,
if any) and interest on the

                                      -70-
<PAGE>
 
Securities of that series in accordance with the terms of the Securities and
this Indenture.

SECTION 10.02. Maintenance of Office or Agency.

          The Company will maintain in the City of Chicago, Illinois, for any
series of Securities, an office or agency where Securities of that series may be
presented or surrendered for payment, where Securities of that series may be
surrendered for registration of transfer or exchange and where notices to and
demands upon the Company in respect of the Securities of that series and this
Indenture may be served. Unless otherwise designated by the Company in a written
notice to the Trustee, such office or agency for all purposes shall be the
Corporate Trust Office of the Trustee. The Company will give prompt written
notice to the Trustee of the location, and any change in the location, of such
office or agency. If at any time the Company shall fail to maintain 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 in the City of Chicago,
Illinois, and the Company hereby appoints the Trustee as its agent to receive
all such presentations, surrenders, notices and demands.

SECTION 10.03. Money for Securities 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 (and premium, if any) or interest on any of the Securities of that
series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal (and premium, if any) or interest
so becoming due until such sums shall be paid to such Persons or 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 (and
premium, if any) or interest on any Securities of that series, deposit with a
Paying Agent a sum sufficient to pay the principal (and premium, if any) or
interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such principal, premium or interest, and (unless such Paying
Agent is the Trustee) the Paying Agent will promptly notify the Trustee of the
Company's 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:

                                      -71-
<PAGE>
 
          (1) hold all sums held by it for the payment of the principal of (and
     premium, if any) or interest on Securities of that series 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;

          (2) give the Trustee notice of any default by the Company (or any
     other obligor upon the Securities of that series) in the making of any
     payment of principal (and premium, if any) or interest on the Securities of
     that series; and

          (3) at any time during the continuance of any such default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent.

          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 (and premium,
if any) or interest on any Security of any series and remaining unclaimed for
three years after such principal (and premium, if any) 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 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 published in
the English language, customarily published on each Business Day and of general
circulation in the Borough of Manhattan, The City of New York, 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.

SECTION 10.04. Corporate 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 corporate
existence and that of each Subsidiary and the rights (charter and statutory) and
franchises of the Company and its Subsidiaries; provided, however, that the
Company shall not be required to preserve any such right or franchise if the
Company shall determine that the preservation thereof is no longer desirable in
the conduct of the business of the Company and its Subsidiaries considered as a
whole.

SECTION 10.05. 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 and maintenance of any of such properties, or disposing of any of
them, if such discontinuance or disposal is, in the judgment of the Company or
of the Subsidiary concerned, desirable in the conduct of its business or the
business of any Subsidiary and not disadvantageous in any material respect to
the Holders.

SECTION 10.06. 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 material 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 and the Company shall have set aside on its books adequate reserves
with respect thereto (segregated to the extent required by generally accepted
accounting principles).

SECTION 10.07. Limitation on Indebtedness Secured by a Mortgage.

          So long as the Securities of any series shall remain Outstanding, the
Company covenants and agrees that neither it nor any Restricted Subsidiary will
create, assume, guarantee or

                                      -73-
<PAGE>
 
suffer to exist any Indebtedness secured by a Mortgage on any assets of the
Company or any Restricted Subsidiary unless the Company secures or causes such
Restricted Subsidiary to secure the Securities of that series equally and
ratably with, or prior to, such secured Indebtedness; provided, however, that
this restriction shall not apply to Indebtedness secured by

          (a) Mortgages on the property of any corporation which Mortgages
     existed at the time such corporation became a Restricted Subsidiary,

          (b) Mortgages in favor of the Company or a Restricted Subsidiary,

     any indebtedness incurred for the purpose of financing all or any part of
     the purchase price or the cost of the construction or improvement of the
     property subject to such Mortgages,

          (d) Mortgages on any property hereafter acquired by the Company or any
     Restricted Subsidiary, contemporaneously with such acquisition or within
     120 days thereafter, to secure or provide for the payment of any part of
     the purchase price of such property, or Mortgages assumed by the Company or
     any Restricted Subsidiary upon any property hereafter acquired by the
     Company or any such Restricted Subsidiary which were existing at the time
     of such acquisition, provided that the amount of any Indebtedness secured
     by any such Mortgage created or assumed shall not exceed the cost to the
     Company or such Restricted Subsidiary, as the case may be, of the property
     covered by such Mortgage,

          (e) any extension, renewal or refunding (or successive extension,
     renewal or refunding), in whole or in part, of any Mortgage referred to in
     the foregoing clauses (a) through (d), inclusive, or of any indebtedness
     secured thereby, and

          (f) any other Mortgage, other than Mortgages referred to in the
     foregoing clauses (a) through (e), inclusive, so long as the aggregate of
     all Indebtedness secured by Mortgages pursuant to this clause (f) and the
     aggregate Value of the Sale and Lease-Back Transactions in existence at
     such time (not including Sale and Lease-Back Transactions as to which the

     exceed 10% of the Consolidated Net Tangible Assets of the Company and its

          For purposes of this Section 10.07 the following terms shall have the
following meanings:

          (1) "Indebtedness" means (i) all items which in accordance with
     generally accepted accounting principles would be included in determining

     broadcast rights), (ii) to the extent not included in clause (i) above,
     indebtedness secured by any mortgage, pledge or lien existing on property
     owned subject to such mortgage, pledge or lien, whether or not the

     of the Company and its Consolidated Subsidiaries;

          (4) "Net Worth" means the aggregate amount of stockholders' investment

will enter into any arrangement with any Person (other than the Company or a

Company, or a Subsidiary, for a period, including renewals, of more than three
years of any Principal Property which has been or is to be sold or transferred
by the Company or such Subsidiary to such Person or to any other Person (other
than the Company or a Subsidiary) to which funds have been or are to be advanced
by such Person on the security of such leased property (in this Article Ten
called a "Sale and Lease-Back Transaction") unless either:

          (a) The Company or such Subsidiary would be entitled to create,
     assume, guarantee or suffer Indebtedness secured by a Mortgage under any
     provision of clauses (a) through (e) of Section 10.07 or, pursuant to the

     ratably securing the Securities; or

          (b) The Company within four months after the effective date of such
     Sale and Lease-Back Transaction (whether made by the Company or a
     Subsidiary) applies to the voluntary retirement of Indebtedness of the

     Securities may only be redeemed in accordance with the terms of such
     series) maturing by the terms thereof more than one year after the original
     creation thereof and ranking at least pari passu with the Securities
     (hereinafter in this Section called "Funded Debt") an amount equal to the
     greater of (i) the net proceeds of the sale of the property subject to the
     Sale and Lease-Back Transaction and (ii) the Value of such Sale and Lease-

in either case divided first by the number of full years of the terms of the
lease and then multiplied by the number of the full years of such term remaining
at the time of determination, without regard to any renewal or extension options
contained in the lease.

          The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Sections 10.04 to 10.08, inclusive,
with respect to the Securities of any series if before or after the time for
such compliance the Holders of a majority in principal amount of the Outstanding
Securities of such series shall, by Act of such Holders, either waive such
compliance in such instances or generally waive compliance with such term,
provision or condition, but no such waiver shall extend to or affect such term,
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 term, provision or condition shall remain in
full force and effect.

SECTION 11.01. 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

                                      -77-
<PAGE>
 
Section 3.01 for Securities of any series) in accordance with this Article.

SECTION 11.02. Election to Redeem; Notice to Trustee.

          In case of any redemption at the election of the Company of less than

the Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date and of
the principal amount of Securities of such series 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 11.03. Selection by Trustee of Securities to Be Redeemed.

          If less than all the Securities of any series 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 denominations 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 that series.

          The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption and, in the 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 11.04. 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

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,
     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 11.05. Deposit of Redemption Price.

          On or 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 10.03) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be the date for an installment of interest) accrued interest on, all
the Securities which are to be redeemed on that date.

SECTION 11.06. 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 installments of interest whose
due date is on or prior to the Redemption Date shall 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 date with respect to such
installments of interest according to their terms and the provisions of Section
3.07.

                                      -79-
 
<PAGE>
 
          If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate prescribed
therefor in the Security.

SECTION 11.07. Securities Redeemed in Part.

          Any Security which is to be redeemed only in part shall be surrendered
at a specified 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, 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.


                                  ARTICLE XII

                                 SINKING FUNDS

          The minimum amount of any sinking fund payment provided for by the
terms of 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 Securities of any

as provided in Section 12.02. Each sinking fund payment shall be applied to the
redemption of Securities of any series as provided for by the terms of
Securities of such series.

Company pursuant to the terms of such Securities or through the application of
permitted

                                      -80-

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 12.03. Redemption of Securities for Sinking Fund.

          Not less than 60 days prior to each sinking fund payment date for any
series of Securities (unless a shorter period shall be satisfactory to the
Trustee), the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of the series, the portion thereof, if any, which is to be
satisfied by payment of cash in the Currency in which the Securities of such
series are denominated (except as provided pursuant to Section 3.01) and the
portion thereof, if any, which is to be satisfied by delivering and crediting
Securities of that series pursuant to Section 12.02 and, prior to or
concurrently with the delivery of such Officers' Certificate, will also deliver
to the Trustee any Securities to be so delivered.  Not less than 45 days before
each 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
11.03 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 11.04.  Such
notice having been duly given, the redemption of such Securities shall be made
upon the terms and in the manner stated in Sections 11.06 and 11.07.

contemplated by Section 3.01 for Securities of such series. Defeasance
provisions, if any, for Securities denominated in a Foreign Currency may be
specified pursuant to Section 3.01.

obligation to comply with any term, provision or condition set forth in Section
8.01, Section 10.04, Section 10.05, Section 10.06, Section 10.07 and Section
10.08 with respect to Securities of any series (and, if so specified pursuant to
Section 3.01, any other restrictive covenant added for the benefit of such
series) 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 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) which 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 interest
     on, the Outstanding Securities of such series on the dates such
     installments of interest or principal are due;

          (2) if the Securities of such series are then listed 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 its option under
     this Section would not cause such Securities to be delisted;

          (3) no Event of Default or event (including such deposit) which, 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 to the effect that Holders of the Securities of such series will
     not
 
                                      -82-
<PAGE>
  
     recognize income, gain or loss for Federal income tax purposes as a result
     of the Company's exercise of its option under this Section and will be
     subject to Federal income tax on the same amount 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 the Securities of such series being
     Discharged, accompanied by a ruling to that effect received from or
     published by the Internal Revenue Service.

          "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
payment of the principal of and the interest on such Securities when such
payments are due, (B) the Company's obligations with respect to the Securities
of such series under Sections 3.05, 3.06, 10.02 and 13.03 and (C) the rights,
powers, trusts, duties and immunities of the Trustee hereunder.

          "U.S. Government Obligations" means securities that are (i) direct
obligations of the United States of America or the payment of which its full
faith and credit is pledged or (ii) obligations of a Person controlled or
supervised by and acting as an agency or instrumentality of the United States of
America the payment of which is unconditionally guaranteed as a full faith and
credit obligation by the United States of America, which in either case under
clauses (i) or (ii) are not callable or redeemable at the option of the 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
depository receipt from any amount received by the custodian in respect of the
U.S. Government Obligation or the specific payment of interest on or principal
of the U.S. Government Obligation evidenced by such depository receipt.

SECTION 13.03. Deposited Moneys and U.S. Government Obligations to Be Held in
               Trust.

          All moneys and U.S. Government Obligations deposited with the Trustee
pursuant to Section 13.02 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

                                      -83-
<PAGE>
  
the Trustee may determine, to the Holders of such Securities, of all sums due
and to become due thereon for principal (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 13.04. Repayment to Company.

          The Trustee and any Paying Agent shall promptly pay or return to the
Company upon Company Request any money or U.S. Government Obligations held by
them at any time that are not required for the payment of the principal of
(premium, if any) and interest on the Securities of any series for which money
or U.S. Government Obligations have been deposited pursuant to Section 13.02.

          The provisions of the last paragraph of Section 10.03 shall apply to
any money held by the Trustee or any Paying Agent under this Article that
remains unclaimed for two years after the Maturity of any series of Securities
for which money or U.S. Government obligations have been deposited pursuant to
Section 13.02.

    TRIBUNE COMPANY, a Delaware corporation (the "Company", which terms include
any successor corporation under the Indenture hereinafter referred to), for
value received, hereby promises to pay to                            , or
registered assigns, the principal sum of                    , on the Stated
Maturity Date specified above (or any Redemption Date or Repayment Date, each as
defined on the reverse hereof) (each such Stated Maturity Date, Redemption Date
or Repayment Date being hereinafter referred to as the "Maturity Date" with
respect to the principal repayable on such date) and to pay interest thereon, at
a rate per annum equal to the Initial Interest Rate specified above until the
Initial Interest Reset Date specified above and thereafter at a rate determined
in accordance with the provisions specified above and on the reverse hereof with
respect to one or more Interest Rate Bases specified above until the principal
hereof is paid or duly made available for payment, and (to the extent that the
payment of such interest shall be legally enforceable) at the Default Rate per
annum specified above on any overdue principal, premium and/or interest.  The
Company will pay interest in arrears on each Interest Payment Date, if any,
specified above (each, an "Interest Payment Date"), commencing with the first
Interest Payment Date next succeeding the Original Issue Date specified above,
and on the Maturity Date; provided, however, that if the Original Issue Date
occurs between a Record Date (as defined below) and the next succeeding Interest
Payment Date, interest payments will commence on the second Interest Payment
Date next succeeding the Original Issue Date to the holder of this Note on the
Record Date with respect to such second Interest Payment Date.
                        
    Interest on this Note will accrue from, and including, the immediately
preceding Interest Payment Date to which interest has been paid or duly provided
for (or from, and including, the Original Issue Date if no interest has been
paid or duly provided for) to, but excluding, the applicable Interest Payment
Date or the Maturity Date, as the case may be (each, an "Interest Period").  The
interest so payable, and punctually paid or duly provided for, on any Interest
Payment Date will, subject to certain exceptions described herein, be paid to
the person in whose name this Note (or one or more predecessor Notes) is
registered at the close of business on the fifteenth calendar day (whether or
not a Business Day, as defined on the reverse hereof) immediately preceding such
Interest Payment Date (the "Record Date"); provided, however, that interest
payable on the Maturity Date will be payable to the person to whom the principal
hereof and premium, if any, hereon shall be payable.  Any such interest not so
punctually paid or duly provided for ("Defaulted Interest") will forthwith cease
to be payable to the holder on any Record Date, and shall be paid to the person
in whose name this Note is registered at the close of business on a special
record date (the "Special Record Date") for the payment of such Defaulted
Interest to be fixed by the Trustee hereinafter referred to, notice whereof
shall be given to the holder of this Note by the Trustee not less than 15
calendar days prior to such Special Record Date or may be paid at any time in
any other lawful manner not inconsistent with the requirements of any securities
exchange on which this note may be listed, and upon such notice as 

                                       3
<PAGE>
 
may be required by such exchange, all as more fully provided for in the
Indenture.

    Payment of principal, premium, if any, and interest in respect of this Note
due on the Maturity Date will be made in immediately available funds upon
presentation and surrender of this Note (and, with respect to any applicable
repayment of this Note, a duly completed election form as contemplated on the
reverse hereof) at the corporate trust office of the Trustee maintained for
that purpose in the Borough of Manhattan, The City of New York, currently
located at [ADDRESS], New York, New York [ZIP CODE], or at such other paying
agency in the Borough of Manhattan, The City of New York, as the Company may
determine; provided, however, that if such payment is to be made in a Specified
Currency other than United States dollars as set forth below, such payment will
be made by wire transfer of immediately available funds to an account with a
bank designated by the holder hereof at least 16 calendar days prior to the
Maturity Date, provided that such bank has appropriate facilities therefor and
that this Note (and, if applicable, a duly completed repayment election form) is
presented and surrendered at the aforementioned office of the Trustee in
time for the Trustee to make such payment in such funds in accordance with
its normal procedures. Payment of interest due on any Interest Payment Date
other than the Maturity Date will be made by check mailed to the address of the
person entitled thereto as such address shall appear in the Security Register
maintained at the aforementioned office of the Trustee; provided, however,
that a holder of U.S.$10,000,000 (or, if the Specified Currency specified above
is other than United States dollars, the equivalent thereof in the Specified
Currency) or more in aggregate principal amount of Notes (whether having
identical or different terms and provisions) will be entitled to receive
interest payments on such Interest Payment Date by wire transfer of immediately
available funds if appropriate wire transfer instructions have been received in
writing by the Trustee not less than 16 calendar days prior to such
Interest Payment Date. Any such wire transfer instructions received by the
Trustee shall remain in effect until revoked by such holder.

    If any Interest Payment Date other than the Maturity Date would otherwise be
a day that is not a Business Day, such Interest Payment Date shall be postponed
to the next succeeding Business Day, except that if LIBOR is an applicable
Interest Rate Basis and such Business Day falls in the next succeeding calendar
month, such Interest Payment Date shall be the immediately preceding Business
Day.  If the Maturity Date falls on a day that is not a Business Day, the
required payment of principal, premium, if any, and interest shall be made on
the next succeeding Business Day with the same force and effect as if made on
the date such payment was due, and no interest shall accrue with respect to such
payment for the period from and after the Maturity Date to the date of such
payment on the next succeeding Business Day.

    The Company is obligated to make payment of principal, premium, if any, and
interest in respect of this Note in the Specified Currency (or, if the Specified
Currency is not at the 

                                       4
<PAGE>
 
time of such payment legal tender for the payment of public and private debts,
in such other coin or currency of the country which issued the Specified
Currency as at the time of such payment is legal tender for the payment of such
debts). If the Specified Currency is other than United States dollars, any such
amounts so payable by the Company will be converted by the Exchange Rate Agent
specified above into United States dollars for payment to the holder of this
Note; provided, however, that the holder of this Note may elect to receive such
amounts in such Specified Currency pursuant to the provisions set forth below.

    If the Specified Currency is other than United States dollars and the holder
of this Note shall not have duly made an election to receive all or a specified
portion of any payment of principal, premium, if any, and/or interest in respect
of this Note in the Specified Currency, any United States dollar amount to be
received by the holder of this Note will be based on the highest bid quotation
in The City of New York received by the Exchange Rate Agent at approximately
11:00 A.M., New York City time, on the second Business Day preceding the
applicable payment date from three recognized foreign exchange dealers (one of
whom may be the Exchange Rate Agent) selected by the Exchange Rate Agent and
approved by the Company for the purchase by the quoting dealer of the Specified
Currency for United States dollars for settlement on such payment date in the
aggregate amount of the Specified Currency payable to all holders of Notes
scheduled to receive United States dollar payments and at which the applicable
dealer commits to execute a contract. All currency exchange costs will be borne
by the holder of this Note by deductions from such payments. If three such bid
quotations are not available, payments on this Note will be made in the
Specified Currency.

    If the Specified Currency is other than United States dollars, the holder of
this Note may elect to receive all or a specified portion of any payment of
principal, premium, if any, and/or interest in respect of this Note in the
Specified Currency by submitting a written request for such payment to the
Trustee at its corporate trust office in The City of New York on or prior
to the applicable Record Date or at least 16 calendar days prior to the Maturity
Date, as the case may be.  Such written request may be mailed or hand delivered
or sent by cable, telex or other form of facsimile transmission.  The holder of
this Note may elect to receive all or a specified portion of all future payments
in the Specified Currency in respect of such principal, premium, if any, and/or
interest and need not file a separate election for each payment.  Such election
will remain in effect until revoked by written notice to the Trustee, but
written notice of any such revocation must be received by the Trustee on or
prior to the applicable Record Date or at least 16 calendar days prior to the
Maturity Date, as the case may be.

    If the Specified Currency is other than United States dollars or a composite
currency and the holder of this Note shall have duly made an election to receive
all or a specified portion of any payment of principal, premium, if any, and/or
interest in respect of this Note in the Specified 

                                       5
<PAGE>
 
Currency and if the Specified Currency is not available due to the imposition of
exchange controls or other circumstances beyond the control of the Company, the
Company will be entitled to satisfy its obligations to the holder of this Note
by making such payment in United States dollars on the basis of the Market
Exchange Rate (as defined below) on the second Business Day prior to such
payment date or, if such Market Exchange Rate is not then available, on the
basis of the most recently available Market Exchange Rate or as otherwise
specified on the face hereof. The "Market Exchange Rate" for the Specified
Currency means the noon dollar buying rate in The City of New York for cable
transfers for the Specified Currency as certified for customs purposes by (or if
not so certified, as otherwise determined by) the Federal Reserve Bank of New
York. Any payment made under such circumstances in United States dollars will
not constitute an Event of Default (as defined in the Indenture).

    If the Specified Currency is a composite currency and the holder of this
Note shall have duly made an election to receive all or a specified portion of
any payment of principal, premium, if any, and/or interest in respect of this
Note in the Specified Currency and if such composite currency is unavailable due
to the imposition of exchange controls or other circumstances beyond the control
of the Company, then the Company will be entitled to satisfy its obligations to
the holder of this Note by making such payment in United States dollars.  The
amount of each payment in United States dollars shall be computed by the
Exchange Rate Agent on the basis of the equivalent of the composite currency in
United States dollars.  The component currencies of the composite currency for
this purpose (collectively, the "Component Currencies" and each, a "Component
Currency") shall be the currency amounts that were components of the composite
currency as of the last day on which the composite currency was used.  The
equivalent of the composite currency in United States dollars shall be
calculated by aggregating the United States dollar equivalents of the Component
Currencies.  The United States dollar equivalent of each of the Component
Currencies shall be determined by the Company or the Exchange Rate Agent on the
basis of the most recently available Market Exchange Rate for each such
Component Currency, or as otherwise specified on the face hereof.

    If the official unit of any Component Currency is altered by way of
combination or subdivision, the number of units of the currency as a Component
Currency shall be divided or multiplied in the same proportion.  If two or more
Component Currencies are consolidated into a single currency, the amounts of
those currencies as Component Currencies shall be replaced by an amount in such
single currency equal to the sum of the amounts of the consolidated Component
Currencies expressed in such single currency.  If any Component Currency is
divided into two or more currencies, the amount of the original Component
Currency shall be replaced by the amounts of such two or more currencies, the
sum of which shall be equal to the amount of the original Component Currency.

    All determinations referred to above made by the Company or its agent
(including the Exchange Rate Agent) shall be at its sole 

                                       6
<PAGE>
 
discretion and shall, in the absence of manifest error, be conclusive for all
purposes and binding on the holder of this Note.

    Reference is hereby made to the further provisions of this Note set forth on
the reverse hereof and, if so specified above, in the Addendum hereto, which
further provisions shall have the same force and effect as if set forth on the
face hereof.

    Notwithstanding any provisions to the contrary contained herein, if the face
of this Note specifies that an Addendum is attached hereto or that
"Other/Additional Provisions" apply, this Note shall be subject to the terms set
forth in such Addendum or such "Other/Additional Provisions".

    Unless the Certificate of Authentication hereon has been executed by the
Trustee by manual signature, this Note shall not be entitled to any benefit
under the Indenture or be valid or obligatory for any purpose.

to time (the "Indenture"), between the Company and First Trust of Illinois,
National Association, as Successor Trustee (the "Trustee", which term includes
any successor trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Trustee and the holders of the Debt Securities, and of the
terms upon which the Debt Securities are, and are to be, authenticated and
delivered.  This Note is one of the series of Debt Securities designated as
"Medium-Term Notes Due Nine Months or More From Date of Issue" (the "Notes").
All terms used but not defined in this Note specified on the face hereof or in
an Addendum hereto shall have the meanings assigned to such terms in the
Indenture.

          This Note is issuable only in registered form without coupons in
minimum denominations of U.S.$1,000 and integral multiples thereof or the
minimum Authorized Denomination specified on the face hereof.

          This Note will not be subject to any sinking fund and, unless
otherwise provided on the face hereof in accordance with the provisions of the
following two paragraphs, will not be redeemable or repayable prior to the
Stated Maturity Date.

          This Note will be subject to redemption at the option of the Company
on any date on or after the Initial Redemption Date, if any, specified on the
face hereof, in whole or from time to time in part in increments of U.S.$1,000
or the minimum Authorized Denomination (provided that any remaining principal
amount hereof shall be at least U.S.$1,000 or such minimum Authorized
Denomination), at the Redemption Price (as defined below), together with unpaid
interest accrued thereon to the date fixed for redemption (each, a "Redemption
Date"), on notice given no more than 60 nor less than 30 calendar days prior to
the Redemption Date and in accordance with the provisions of the Indenture.  The
"Redemption Price" shall initially be the Initial Redemption Percentage
specified on the face hereof multiplied by the unpaid principal amount of this
Note to be redeemed.  The Initial Redemption Percentage shall decline at each
anniversary of the Initial Redemption Date by the Annual Redemption Percentage
Reduction, if any, specified on the face hereof until the Redemption Price is
100% of unpaid principal amount to be redeemed.  In the event of redemption of
this Note in part only, a new Note of like tenor for the unredeemed portion
hereof and otherwise having 
                        




                                       9

the same terms as this Note shall be issued in the name of the holder hereof
upon the presentation and surrender hereof.

          This Note will be subject to repayment by the Company at the option of
the holder hereof on the Optional Repayment Date(s), if any, specified on the
face hereof, in whole or in part in increments of U.S.$1,000 or the minimum
Authorized Denomination (provided that any remaining principal amount hereof
shall be at least U.S.$1,000 or such minimum Authorized Denomination), at a
repayment price equal to 100% of the unpaid principal amount to be repaid,
together with unpaid interest accrued thereon to the date fixed for repayment
(each, a "Repayment Date").  For this Note to be repaid, this Note must be
received, together with the form hereon entitled "Option to Elect Repayment"
duly completed, by the Trustee at its corporate trust office not more than 60
nor less than 30 calendar days prior to the Repayment Date.  Exercise of such
repayment option by the holder hereof will be irrevocable.  In the event of
repayment of this Note in part only, a new Note of like tenor for the unrepaid
portion hereof and otherwise having the same terms as this Note shall be issued
in the name of the holder hereof upon the presentation and surrender hereof.

          If the Interest Category of this Note is specified on the face hereof
as an Original Issue Discount Note, the amount payable to the holder of this
Note in the event of redemption, repayment or acceleration of maturity of this
Note will be equal to the sum of (1) the Issue Price specified on the face
hereof (increased by any accruals of the Discount, as defined below) and, in the
event of any redemption of this Note (if applicable), multiplied by the Initial
Redemption Percentage (as adjusted by the Annual Redemption Percentage
Reduction, if applicable) and (2) any unpaid interest on this Note accrued from
the Original Issue Date to the Redemption Date, Repayment Date or date of
acceleration of maturity, as the case may be.  The difference between the Issue
Price and 100% of the principal amount of this Note is referred to herein as the
"Discount."

          For purposes of determining the amount of Discount that has accrued as
of any Redemption Date, Repayment Date or date of acceleration of maturity of
this Note, such Discount will be accrued so as to cause an assumed yield on the
Note to be constant.  The assumed constant yield will be calculated using a 30-
day month, 360-day year convention, a compounding period that, except for the
Initial Period (as defined below), corresponds to the shortest period between
Interest Payment Dates (with ratable accruals within a compounding period), a
constant coupon rate equal to the initial interest rate applicable to this Note
and an assumption that the maturity of this Note will not be accelerated.  If
the period from the Original Issue Date to the initial Interest Payment Date
(the "Initial Period") is shorter than the compounding period for this Note, a
proportionate amount of the yield for an entire compounding period will be
accrued.  If the Initial Period is longer than the compounding period, then such
period will be divided into a regular compounding period and a short period,
with the short period being treated as provided in the preceding sentence.

   The interest rate borne by this Note will be determined as follows:

       (i) Unless the Interest Category of this Note is specified on the face
   hereof as a "Floating Rate/Fixed Rate Note", an "Inverse Floating Rate Note"
   or as having an Addendum attached, this Note shall be designated as a
   "Regular Floating Rate Note" and, except as set forth below or on the face
   hereof, shall bear interest at the rate determined by reference to the
   applicable Interest Rate Basis or Bases (a) plus or minus the Spread, if any,
   and/or (b) multiplied by the Spread Multiplier, if any, in each case as
   specified on the face hereof. Commencing on the Initial Interest Reset Date,
   the rate at which interest on this Note shall be payable shall be reset as of
   each Interest Reset Date specified on the face hereof; provided, however,
   that the interest rate in effect for the period, if any, from the Original
   Issue Date to the Initial Interest Reset Date shall be the Initial Interest
   Rate.

       (ii) If the Interest Category of this Note is specified on the face
   hereof as a "Floating Rate/Fixed Rate Note", then, except as set forth below
   or on the face hereof, this Note shall bear interest at the rate determined
   by reference to the applicable Interest Rate Basis or Bases (a) plus or minus
   the Spread, if any, and/or (b) multiplied by the Spread Multiplier, if any.
   Commencing on the Initial Interest Reset Date, the rate at which interest on
   this Note shall be payable shall be reset as of each Interest Reset Date;
   provided, however, that (y) the interest rate in effect for the period, if
   any, from the Original Issue Date to the Initial Interest Reset Date shall be
   the Initial Interest Rate and (z) the interest rate in effect for the period
   commencing on the Fixed Rate Commencement Date specified on the face hereof
   to the Maturity Date shall be the Fixed Interest Rate specified on the face
   hereof or, if no such Fixed Interest Rate is specified, the interest rate in
   effect hereon on the day immediately preceding the Fixed Rate Commencement
   Date.

       (iii) If the Interest Category of this Note is specified on the face
   hereof as an "Inverse Floating Rate Note", then, except as set forth below or
   on the face hereof, this Note shall bear interest at the Fixed Interest Rate
   minus the rate determined by reference to the applicable Interest Rate Basis
   or Bases (a) plus or minus the Spread, if any, and/or (b) multiplied by the
   Spread Multiplier, if any; provided, however, that, unless otherwise
   specified on the face hereof, the interest rate hereon shall not be less than
   zero. Commencing on the Initial Interest Reset Date, the rate at which
   interest on this Note shall be payable shall be reset as of each Interest
   Reset Date; provided, however, that the interest rate in effect for the
   period, if any, from the Original Issue Date to the Initial Interest Reset
   Date shall be the Initial Interest Rate.

                                       11

       Notwithstanding the foregoing, if this Note is designated as having an
   Addendum on the face hereof, this Note shall bear interest in accordance with
   the terms of the Addendum.

       Unless otherwise specified on the face hereof, the rate with respect to
   each Interest Rate Basis will be determined in accordance with the applicable
   provisions below. Except as set forth above or on the face hereof, the
   interest rate in effect on each day shall be (i) if such day is an Interest
   Reset Date, the interest rate determined as of the Interest Determination
   Date (as defined below) immediately preceding such Interest Reset Date or
   (ii) if such day is not an Interest Reset Date, the interest rate determined
   as of the Interest Determination Date immediately preceding the next
   preceding Interest Reset Date.

       If any Interest Reset Date would otherwise be a day that is not a
   Business Day, such Interest Reset Date shall be postponed to the next
   succeeding Business Day, except that if LIBOR is an applicable Interest Rate
   Basis and such Business Day falls in the next succeeding calendar month, such
   Interest Reset Date shall be the immediately preceding Business Day.

       As used herein, "Business Day" means any day that is not a day on which
   banking institutions are authorized or required by law, regulation or
   executive order to close in The City of New York; provided, however, that if
   the Specified Currency is other than United States dollars and any payment is
   to be made in the Specified Currency in accordance with the provisions
   hereof, such day is also not a day on which banking institutions are
   authorized or required by law or executive order to close in the Principal
   Financial Center (as defined below) of the country issuing the Specified
   Currency (or, in the case of European Currency Units ("ECU"), is not a day
   that appears as an ECU non-settlement day on the display designated as "ISDE"
   on the Reuter Monitor Money Rates Service (or a day so designated by the ECU
   Banking Association) or, if ECU non-settlement days do not appear on that
   page (and are not so designated), is not a day on which payments in ECU
   cannot be settled in the international interbank market); provided, further,
   that if LIBOR is an applicable Interest Rate Basis, such day is also a London
   Business Day (as defined below). "London Business Day" means (i) if the Index
   Currency (as defined below) is other than ECU, any day on which dealings in
   such Index Currency are transacted in the London interbank market or (ii) if
   the Index Currency is ECU, any day that does not appear as an ECU non-
   settlement day on the display designated as "ISDE" on the Reuter Monitor
   Money Rates Service (or a day so designated by the ECU Banking Association)
   or, if ECU non-settlement days do not appear on that page (and are not so
   designated), is not a day on which payments in ECU cannot be settled in the
   international interbank market. "Principal Financial Center" means the
   capital city of the country issuing the Specified Currency, or solely with
   respect to the calculation of LIBOR, the Index Currency, except that with
   respect to United States dollars, Australian dollars, Deutsche marks, Dutch
   guilders, Italian lire, Swiss francs and ECU, the "Principal Financial
   Center" shall be The City of New York, Sydney, Frankfurt, Amsterdam, Milan,
   Zurich and Luxembourg, respectively.

          The "Interest Determination Date" with respect to the CD Rate, the CMT
Rate, the Commercial Paper Rate, the Federal Funds Rate and the Prime Rate will
be the second Business Day immediately preceding the applicable Interest Reset
Date; the "Interest Determination Date" with respect to the Eleventh District
Cost of Funds Rate shall be the last working day of the month immediately
preceding the applicable Interest Reset Date on which the Federal Home Loan Bank
of San Francisco (the "FHLB of San Francisco") publishes the Index (as defined
below); and the "Interest Determination Date" with respect to LIBOR shall be the
second London Business Day immediately preceding the applicable Interest Reset
Date, unless the Index Currency is British pounds sterling, in which case the
"Interest Determination Date" will be the applicable Interest Reset Date.  The
"Interest Determination Date" with respect to the Treasury Rate shall be the day
in the week in which the applicable Interest Reset Date falls on which day
Treasury Bills (as defined below) are normally auctioned (Treasury Bills are
normally sold at an auction held on Monday of each week, unless that day is a
legal holiday, in which case the auction is normally held on the following
Tuesday, except that such auction may be held on the preceding Friday);
provided, however, that if an auction is held on the Friday of the week
preceding the applicable Interest Reset Date, the Interest Determination Date
shall be such preceding Friday; and provided, further, that if an auction falls
on any Interest Reset Date, then the related Interest Reset Date will instead be
the first Business Day following such auction.  If the interest rate of this
Note is determined with reference to two or more Interest Rate Bases specified
on the face hereof, the "Interest Determination Date" pertaining to this Note
shall be the most recent Business Day which is at least two Business Days prior
to the applicable Interest Reset Date on which each Interest Rate Basis is
determinable. Each Interest Rate Basis shall be determined as of such date, and
the applicable interest rate shall take effect on the related Interest Reset
Date.

          CD Rate.  If an Interest Rate Basis for this Note is specified on the
face hereof as the CD Rate, the CD Rate shall be determined as of the applicable
Interest Determination Date (a "CD Rate Interest Determination Date") as the
rate on such date for negotiable United States dollar certificates of deposit
having the Index Maturity specified on the face hereof as published by the Board
of Governors of the Federal Reserve System in "Statistical Release H.15(519),
Selected Interest Rates" or any successor publication ("H.15(519)") under the
heading "CDs (Secondary Market)", or, if not published by 3:00 P.M., New York
City time, on the related Calculation Date (as defined below), the rate on such
CD Rate Interest Determination Date for negotiable United States dollar
certificates of deposit of the Index Maturity as published by the Federal
Reserve Bank of New York in its daily statistical release "Composite 3:30 P.M.
Quotations for United States Government Securities" or any successor publication
("Composite Quotations") under the heading "Certificates of Deposit". If such
rate is not yet published in either H.15(519) or Composite Quotations by 3:00
P.M., New York City time, on the related Calculation Date, then the CD Rate on
such CD Rate Interest Determination Date will be calculated by the Calculation
Agent 


                                       13
<PAGE>
 
specified on the face hereof and will be the arithmetic mean of the secondary
market offered rates as of 10:00 A.M., New York City time, on such CD Rate
Interest Determination Date, of three leading nonbank dealers in negotiable
United States dollar certificates of deposit in The City of New York selected by
the Calculation Agent for negotiable certificates of deposit of major United
States money market banks for negotiable United States dollar certificates of
deposit with a remaining maturity closest to the Index Maturity in an amount
that is representative for a single transaction in that market at that time;
provided, however, that if the dealers so selected by the Calculation Agent are
not quoting as mentioned in this sentence, the CD Rate determined as of such CD
Rate Interest Determination Date will be the CD Rate in effect on such CD Rate
Interest Determination Date.

          CMT Rate.  If an Interest Rate Basis for this Note is specified on the
face hereof as the CMT rate, the CMT Rate shall be determined as of the
applicable Interest Determination Date (a "CMT Rate Interest Determination
Date") as the rate displayed on the Designated CMT Telerate Page (as defined
below) under the caption "...Treasury Constant Maturities...Federal Reserve
Board Release H.15...Mondays Approximately 3:45 P.M.", under the column for the
Designated CMT Maturity Index (as defined below) for (i) if the Designated CMT
Telerate Page is 7055, the rate on such CMT Rate Interest Determination Date and
(ii) if the Designated CMT Telerate Page is 7052, the week, or the month, as
applicable, ended immediately preceding the week in which the related CMT Rate
Interest Determination Date occurs.  If such rate is no longer displayed on the
relevant page or is not displayed by 3:00 P.M., New York City time, on the
related Calculation Date, then the CMT Rate for such CMT Rate Interest
Determination Date will be such treasury constant maturity rate for the
Designated CMT Maturity Index as published in the relevant H.15(519).  If such
rate is no longer published or is not published by 3:00 P.M., New York City
time, on the related Calculation Date, then the CMT Rate on such CMT Rate
Interest Determination Date will be such treasury constant maturity rate for the
Designated CMT Maturity Index (or other United States Treasury rate for the
Designated CMT Maturity Index) for the CMT Rate Interest Determination Date with
respect to such Interest Reset Date as may then be published by either the Board
of Governors of the Federal Reserve System or the United States Department of
the Treasury that the Calculation Agent determines to be comparable to the rate
formerly displayed on the Designated CMT Telerate Page and published in the
relevant H.15(519).  If such information is not provided by 3:00 P.M., New York
City time, on the related Calculation Date, then the CMT Rate on the CMT Rate
Interest Determination Date will be calculated by the Calculation Agent and will
be a yield to maturity, based on the arithmetic mean of the secondary market
closing offer side prices as of approximately 3:30 P.M., New York City time, on
such CMT Rate Interest Determination Date reported, according to their written
records, by three leading primary United States government securities dealers
(each, a "Reference Dealer") in The City of New York (which may include the
Agent or its Affiliates) selected by the Calculation Agent (from five such
Reference Dealers selected by the Calculation Agent and eliminating the highest
quotation (or, in 



                                       14
<PAGE>
 
the event of equality, one of the highest) and the lowest quotation (or,
in the event of equality, one of the lowest)), for the most recently issued
direct noncallable fixed rate obligations of the United States ("Treasury
Notes") with an original maturity of approximately the Designated CMT Maturity
Index and a remaining term to maturity of not less than such Designated CMT
Maturity Index minus one year. If the Calculation Agent is unable to obtain
three such Treasury Note quotations, the CMT Rate on such CMT Rate Interest
Determination Date will be calculated by the Calculation Agent and will be a
yield to maturity based on the arithmetic mean of the secondary market offer
side prices as of approximately 3:30 P.M., New York City time, on such CMT Rate
Interest Determination Date of three Reference Dealers in The City of New York
(from five such Reference Dealers selected by the Calculation Agent and
eliminating the highest quotation (or, in the event of equality, one of the
highest) and the lowest quotation (or, in the event of equality, one of the
lowest)), for Treasury Notes with an original maturity of the number of years
that is the next highest to the Designated CMT Maturity Index and a remaining
term to maturity closest to the Designated CMT Maturity Index and in an amount
of at least U.S.$100 million. If three or four (and not five) of such Reference
Dealers are quoting as described above, then the CMT Rate will be based on the
arithmetic mean of the offer prices obtained and neither the highest nor the
lowest of such quotes will be eliminated; provided, however, that if fewer than
three Reference Dealers selected by the Calculation Agent are quoting as
mentioned herein, the CMT Rate determined as of such CMT Rate Interest
Determination Date will be the CMT Rate in effect on such CMT Rate Interest
Determination Date. If two Treasury Notes with an original maturity as described
in the second preceding sentence have remaining terms to maturity equally close
to the Designated CMT Maturity Index, the Calculation Agent will obtain from
five Reference Dealers quotations for the Treasury Note with the shorter
remaining term to maturity.

          "Designated CMT Telerate Page" means the display on the Dow Jones
Telerate Service on the page specified on the face hereof (or any other page as
may replace such page on that service for the purpose of displaying Treasury
Constant Maturities as reported in H.15(519)) for the purpose of displaying
Treasury Constant Maturities as reported in H.15(519).  If no such page is
specified on the face hereof, the Designated CMT Telerate Page shall be 7052,
for the most recent week.

          "Designated CMT Maturity Index" means the original period to maturity
of the United States Treasury securities (either 1, 2, 3, 5, 7, 10, 20 or 30
years) specified on the face hereof with respect to which the CMT Rate will be
calculated.  If no such maturity is specified on the face hereof, the Designated
CMT Maturity Index shall be 2 years.

          Commercial Paper Rate.  If an Interest Rate Basis for this Note is
specified on the face hereof as the Commercial Paper Rate, the Commercial Paper
Rate shall be determined as of the applicable Interest Determination Date (a
"Commercial Paper Rate Interest Determination Date") as the Money Market Yield
(as defined below) 

                                       15
<PAGE>
 
on such date of the rate for commercial paper having the Index Maturity as
published in H.15(519) under the heading "Commercial Paper". In the event that
such rate is not published by 3:00 P.M., New York City time, on such Calculation
Date, then the Commercial Paper Rate on such Commercial Paper Rate Interest
Determination Date will be the Money Market Yield of the rate for commercial
paper having the Index Maturity as published in Composite Quotations under the
heading "Commercial Paper" (with an Index Maturity of one month or three months
being deemed to be equivalent to an Index Maturity of 30 days or 90 days,
respectively). If such rate is not yet published in either H.15(519) or
Composite Quotations by 3:00 P.M., New York City time, on such Calculation Date,
then the Commercial Paper Rate on such Commercial Paper Rate Interest
Determination Date will be calculated by the Calculation Agent and shall be the
Money Market Yield of the arithmetic mean of the offered rates at approximately
11:00 A.M., New York City time, on such Commercial Paper Rate Interest
Determination Date of three leading dealers of commercial paper in The City of
New York selected by the Calculation Agent for commercial paper having the Index
Maturity placed for an industrial issuer whose bond rating is "AA", or the
equivalent from a nationally recognized statistical rating organization;
provided, however, that if the dealers so selected by the Calculation Agent are
not quoting as mentioned in this sentence, the Commercial Paper Rate determined
as of such Commercial Paper Rate Interest Determination Date will be the
Commercial Paper Rate in effect on such Commercial Paper Rate Interest
Determination Date.

          "Money Market Yield" means a yield (expressed as a percentage)
calculated in accordance with the following formula:

                                           D x 360        
               Money Market Yield = --------------------- x  100
                                        360 - (D x M)

where "D" refers to the applicable per annum rate for commercial paper quoted on
a bank discount basis and expressed as a decimal, and "M" refers to the actual
number of days in the Interest Period for which interest is being calculated.

          Eleventh District Cost of Funds Rate.  If an Interest Rate Basis for
this Note is specified on the face hereof as the Eleventh District Cost of Funds
Rate, the Eleventh District Cost of Funds Rate shall be determined as of the
applicable Interest Determination Date (an "Eleventh District Cost of Funds Rate
Interest Determination Date") as the rate equal to the monthly weighted average
cost of funds for the calendar month immediately preceding the month in which
such Eleventh District Cost of Funds Rate Interest Determination Date falls, as
set forth under the caption "11th District" on Telerate Page 7058 as of 11:00
A.M., San Francisco time, on such Eleventh District Cost of Funds Rate Interest
Determination Date.  If such rate does not appear on Telerate Page 7058 on such
Eleventh District Cost of Funds Rate Interest Determination Date, then the
Eleventh District Cost of Funds Rate on such Eleventh District Cost of Funds
Rate Interest Determination Date shall be the monthly weighted average cost of
funds paid by member institutions of the Eleventh Federal Home Loan 






                                       16
<PAGE>
 
Bank District that was most recently announced (the "Index") by the FHLB of San
Francisco as such cost of funds for the calendar month immediately preceding the
date of such announcement.  If the FHLB of San Francisco fails to announce the
Index on or prior to such Eleventh District Cost of Funds Rate Interest
Determination Date for the calendar month immediately preceding such Eleventh
District Cost of Funds Rate Interest Determination Date, the Eleventh District
Cost of Funds Rate determined as of such Eleventh District Cost of Funds Rate
Interest Determination Date will be the Eleventh District Cost of Funds Rate in
effect on such Eleventh District Cost of Funds Rate Interest Determination Date.

          Federal Funds Rate.  If an Interest Rate Basis for this Note is
specified on the face hereof as the Federal Funds Rate, the Federal Funds Rate
shall be determined as of the applicable Interest Determination Date (a "Federal
Funds Rate Interest Determination Date") as the rate on such date for United
States dollar federal funds as published in H.15(519) under the heading "Federal
Funds (Effective)" or, if not published by 3:00 P.M., New York City time, on the
Calculation Date, the rate on such Federal Funds Rate Interest Determination
Date as published in Composite Quotations under the heading "Federal
Funds/Effective Rate".  If such rate is not published in either H.15(519) or
Composite Quotations by 3:00 P.M., New York City time, on the related
Calculation Date, then the Federal Funds Rate on such Federal Funds Interest
Determination Date shall be calculated by the Calculation Agent and will be the
arithmetic mean of the rates for the last transaction in overnight United States
dollar federal funds arranged by three leading brokers of federal funds
transactions in The City of New York selected by the Calculation Agent, prior to
9:00 A.M., New York City time, on such Federal Funds Rate Interest Determination
Date; provided, however, that if the brokers so selected by the Calculation
Agent are not quoting as mentioned in this sentence, the Federal Funds Rate
determined as of such Federal Funds Rate Interest Determination Date will be the
Federal Funds Rate in effect on such Federal Funds Rate Interest Determination
Date.

          LIBOR.  If an Interest Rate Basis for this Note is specified on the
face hereof as LIBOR, LIBOR shall be determined by the Calculation Agent as of
the applicable Interest Determination Date (a "LIBOR Interest Determination
Date") in accordance with the following provisions:

          (i) if (a) "LIBOR Reuters" is specified on the face hereof, the
arithmetic mean of the offered rates (unless the Designated LIBOR Page (as
defined below) by its terms provides only for a single rate, in which case such
single rate will be used) for deposits in the Index Currency having the Index
Maturity designated on the face hereof, commencing on the second London Business
Day immediately following that LIBOR Interest Determination Date that appear
(or, if only a single rate is required as aforesaid, appears) on the Designated
LIBOR Page (as defined below) as of 11:00 A.M., London time, on such LIBOR
Interest Determination Date, or (b) "LIBOR Telerate" is specified on the face
hereof, or if neither "LIBOR Reuters" nor "LIBOR Telerate" is specified on the

                                       17
<PAGE>
 
face hereof as the method for calculating LIBOR, the rate for deposits in the
Index Currency having the Index Maturity designated on the face hereof,
commencing on the second London Business Day immediately following that LIBOR
Interest Determination Date, that appears on the Designated LIBOR Page as of
11:00 A.M., London time, on such LIBOR Interest Determination Date.  If fewer
than two such offered rates appear, or if no such rate appears, as applicable,
LIBOR on such LIBOR Interest Determination Date shall be determined in
accordance with the provisions described in clause (ii) below.

          (ii) With respect to a LIBOR Interest Determination Date on which
fewer than two offered rates appear, or no rate appears, as the case may be, on
the Designated LIBOR Page as specified in clause (i) above, the Calculation
Agent shall request the principal London offices of each of four major reference
banks in the London interbank market, as selected by the Calculation Agent, to
provide the Calculation Agent with its offered quotation for deposits in the
Index Currency for the period of the Index Maturity, commencing on the second
London Business Day immediately following such LIBOR Interest Determination Date
on the applicable Interest Reset Date, to prime banks in the London interbank
market at approximately 11:00 A.M., London time, on such LIBOR Interest
Determination Date and in a principal amount that is representative for a single
transaction in such Index Currency in such market at such time.  If at least two
such quotations are so provided, then LIBOR on such LIBOR Interest Determination
Date will be the arithmetic mean of such quotations.  If fewer than two such
quotations are so provided, then LIBOR on such LIBOR Interest Determination Date
will be the arithmetic mean of the rates quoted at approximately 11:00 A.M., in
the applicable Principal Financial Center, on such LIBOR Interest Determination
Date by three major banks in such Principal Financial Center selected by the
Calculation Agent for loans in the Index Currency to leading European banks,
having the Index Maturity and in a principal amount that is representative for a
single transaction in such Index Currency in such market at such time; provided,
however, that if the banks so selected by the Calculation Agent are not quoting
as mentioned in this sentence, LIBOR determined as of such LIBOR Interest
Determination Date shall be LIBOR in effect on such LIBOR Interest Determination
Date.

          "Index Currency" means the currency or composite currency specified on
the face hereof as to which LIBOR shall be calculated.  If no such currency or
composite currency is specified on the face hereof, the Index Currency shall be
United States dollars.

          "Designated LIBOR Page" means (a) if "LIBOR Reuters" is specified on
the face hereof, the display on the Reuter Monitor Money Rates Service (or any
successor service) for the purpose of displaying the London interbank rates of
major banks for the Index Currency, or (b) if "LIBOR Telerate" is specified on
the face hereof, the display on the Dow Jones Telerate Service for the purpose
of displaying the London Interbank rates of major banks for the applicable Index
Currency.  If neither "LIBOR Reuters" nor "LIBOR Telerate" is specified on the
face hereof as the method for calculating LIBOR, the display on the Dow Jones
Telerate Service 

                                       18
<PAGE>
 
(or any successor service) for the purpose of displaying the London interbank
rates of major banks for the Index Currency.

          Prime Rate.  If an Interest Rate Basis for this Note is specified on
the face hereto as the Prime Rate, the Prime Rate shall be determined as of the
applicable Interest Determination Date (a "Prime Rate Interest Determination
Date") as the rate on such date as such rate is published in H.15(519) under the
heading "Bank Prime Loan".  If such rate is not published prior to 3:00 P.M.,
New York City time, on the related Calculation Date, then the Prime Rate shall
be the arithmetic mean of the rates of interest publicly announced by each bank
that appears on the Reuters Screen USPRIME1 (as defined below) as such bank's
prime rate or base lending rate as in effect for such Prime Rate Interest
Determination Date.  If fewer than four such rates appear on the Reuters Screen
USPRIME1 for such Prime Rate Interest Determination Date, the Prime Rate shall
be the arithmetic mean of the prime rates quoted on the basis of the actual
number of days in the year divided by a 360-day year as of the close of business
on such Prime Rate Interest Determination Date by four major money center banks
in The City of New York selected by the Calculation Agent.  If fewer than two
such quotations are so provided, the Prime Rate shall be determined by the
Calculation Agent as the arithmetic mean of three prime rates quoted on the
basis of the actual number of days in the year divided by a 360-day year as of
the close of business on such Prime Rate Interest Determination Date as
furnished in The City of New York by substitute banks or trust companies
organized and doing business under the laws of the United States, or any State
thereof, each having total equity capital of at least U.S.$500 million and being
subject to supervision or examination by Federal or State authority, selected by
the Calculation Agent to provide such rate or rates; provided, however, that if
the banks or trust companies so selected by the Calculation Agent are not
quoting as mentioned in this sentence, the Prime Rate determined as of such
Prime Rate Interest Determination Date will be the Prime Rate in effect on such
Prime Rate Interest Determination Date.

          "Reuters Screen USPRIME1" means the display designated as page
"USPRIME1" on the Reuters Monitor Money Rates Service (or such other page as may
replace the USPRIME1 page on that service for the purpose of displaying prime
rates or base lending rates of major United States banks).

          Treasury Rate.  If an Interest Rate Basis for this Note is specified
on the face hereof as the Treasury Rate, the Treasury Rate shall be determined
as of the applicable Interest Determination Date (a "Treasury Rate Interest
Determination Date") as the rate applicable to the most recent auction (the
"Auction") of direct obligations of the United States ("Treasury Bills") having
the Index Maturity, as such rate is published in H.15(519) under the heading
"Treasury bills-auction average (investment)" or, if not published by 3:00 P.M.,
New York City time, on the related Calculation Date, the auction average rate of
such Treasury Bills (expressed as a bond equivalent on the basis of a year of
365 or 366 days, as applicable, and applied on a daily basis) as otherwise

                                       19
<PAGE>
 
announced by the United States Department of the Treasury. In the event that the
results of the Auction of Treasury Bills having the Index Maturity are not
reported as provided above by 3:00 P.M., New York City time, on such Calculation
Date, or if no such Auction is held, then the Treasury Rate shall be calculated
by the Calculation Agent and shall be a yield to maturity (expressed as a bond
equivalent on the basis of a year of 365 or 366 days, as applicable, and applied
on a daily basis) of the arithmetic mean of the secondary market bid rates, as
of approximately 3:30 P.M., New York City time, on such Treasury Rate Interest
Determination Date, of three leading primary United States government securities
dealers (which may include the Agents) selected by the Calculation Agent, for
the issue of Treasury Bills with a remaining maturity closest to the Index
Maturity; provided, however, that if the dealers so selected by the Calculation
Agent are not quoting as mentioned in this sentence, the Treasury Rate
determined as of such Treasury Rate Interest Determination Date will be the
Treasury Rate in effect on such Treasury Rate Interest Determination Date.

          Notwithstanding the foregoing, the interest rate hereon shall not be
greater than the Maximum Interest Rate, if any, or less than the Minimum
Interest Rate, if any, in each case as specified on the face hereof.  The
interest rate on this Note will in no event be higher than the maximum rate
permitted by New York law, as the same may be modified by United States law of
general application.

          The Calculation Agent shall calculate the interest rate hereon on or
before each Calculation Date.  The "Calculation Date", if applicable, pertaining
to any Interest Determination Date shall be the earlier of (i) the tenth
calendar day after such Interest Determination Date or, if such day is not a
Business Day, the next succeeding Business Day or (ii) the Business Day
immediately preceding the applicable Interest Payment Date or the Maturity Date,
as the case may be.  At the request of the Holder hereof, the Calculation Agent
will provide to the Holder hereof the interest rate hereon then in effect and,
if determined, the interest rate that will become effective as a result of a
determination made for the next succeeding Interest Reset Date.

          Accrued interest hereon shall be an amount calculated by multiplying
the principal amount hereof by an accrued interest factor.  Such accrued
interest factor shall be computed by adding the interest factor calculated for
each day in the applicable Interest Period.  Unless otherwise specified as the
Day Count Convention on the face hereof, the interest factor for each such date
shall be computed by dividing the interest rate applicable to such day by 360 if
the CD Rate, the Commercial Paper Rate, the Eleventh District Cost of Funds
Rate, the Federal Funds Rate, LIBOR or the Prime Rate is an applicable Interest
Rate Basis or by the actual number of days in the year if the CMT Rate or the
Treasury Rate is an applicable Interest Rate Basis.  Unless otherwise specified
as the Day Count Convention on the face hereof, the interest factor for this
Note, if the interest rate is calculated with reference to two or more Interest
Rate Bases, shall be calculated in each period in the same manner as if only the

                                       20
<PAGE>
 
Applicable Interest Rate Basis specified on the face hereof applied.

          All percentages resulting from any calculation on this Note shall be
rounded to the nearest one hundred-thousandth of a percentage point, with five
one-millionths of a percentage point rounded upwards, and all amounts used in or
resulting from such calculation on this Note shall be rounded, in the case of
United States dollars, to the nearest cent or, in the case of a Specified
Currency other than United States dollars, to the nearest unit (with one-half
cent or unit being rounded upwards).

          If an Event of Default, as defined in the Indenture, shall occur and
be continuing, the principal of the Notes may be declared due and payable in the
manner and with the effect provided in the Indenture.

          The Indenture contains provisions for defeasance of (i) the entire
indebtedness of the Notes or (ii) certain covenants and Events of Default with
respect to the Notes, in each case upon compliance with certain conditions set
forth therein, which provisions apply to the Notes.

          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the holders of the Debt Securities at any time by the
Company and the Trustee with the consent of the holders of not less than a
majority of the aggregate principal amount of all Debt Securities at the time
outstanding and affected thereby.  The Indenture also contains provisions
permitting the holders of not less than a majority of the aggregate principal
amount of the outstanding Debt Securities of any series, on behalf of the
holders of all such Debt Securities, to waive compliance by the Company with
certain provisions of the Indenture.  Furthermore, provisions in the Indenture
permit the holders of not less than a majority of the aggregate principal amount
of the outstanding Debt Securities of any series, in certain instances, to
waive, on behalf of all of the holders of Debt Securities of such series,
certain past defaults under the Indenture and their consequences.  Any such
consent or waiver by the holder of this Note shall be conclusive and binding
upon such holder and upon all future holders of this Note and other Notes 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
Note.

          No reference herein to the Indenture and no provision of this Note or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay principal, premium, if any, and interest in
respect of this Note at the times, places and rate or formula, and in the coin
or currency, herein prescribed.

          As provided in the Indenture and subject to certain limitations
therein and herein set forth, the transfer of this Note is registrable in the
Security Register of the Company upon 

                                       21

surrender of this Note for registration of transfer at the office or agency of
the Company in any place where the principal hereof and any premium or interest
hereon 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 by his attorney duly authorized in writing,
and thereupon one or more new Notes, of authorized denominations and for the
same aggregate principal amount, will be issued to the designated transferee or
transferees.

          As provided in the Indenture and subject to certain limitations
therein and herein set forth, this Note is exchangeable for a like aggregate
principal amount of Notes of different authorized denominations but otherwise
having the same terms and conditions, as requested by the holder hereof
surrendering the same.

          No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

          Prior to due presentment of this Note for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the holder in whose name this Note is registered as the owner thereof for all
purposes, whether or not this Note be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

          The Indenture and this Note shall be governed by and construed in
accordance with the laws of the State of Illinois applicable to agreements made
and to be performed entirely in such State.

          TRIBUNE COMPANY, a Delaware Corporation (the "Company", which terms
include any successor corporation under the Indenture hereinafter referred to),
for value received, hereby promises to pay to                                ,
or registered assigns, the principal sum of                    , on the Stated
Maturity Date specified above (or any Redemption Date or Repayment Date, each as
defined on the reverse hereof) (each such Stated Maturity Date, Redemption Date
or Repayment Date being hereinafter referred to as the "Maturity Date" with
respect to the principal repayable on such date) and to pay interest thereon, at
the Interest Rate per annum specified above, until the principal hereof is paid
or duly made available for payment, and (to the extent that the payment of such
interest shall be legally enforceable) at the Default Rate per annum specified
above on any overdue principal, premium and/or interest. The Company will pay
interest in arrears on each Interest Payment Date, if any, specified above
(each, an "Interest Payment Date"), commencing with the first Interest Payment
Date next succeeding the Original Issue Date specified above, and on the
Maturity Date; provided, however, that if the Original Issue Date occurs between
a Record Date (as defined below) and the next succeeding Interest Payment Date,
interest payments will commence on the second Interest Payment Date next
succeeding the Original Issue Date to the holder of this Note on the Record Date
with respect to such second Interest Payment Date. Interest on this Note will be
computed on the basis of a 360-day year of twelve 30-day months.

          Notwithstanding the foregoing, if an Addendum is attached hereto or
"Other/Additional Provisions" apply to this Note as specified above, this Note
shall be subject to the terms set forth in such Addendum or such
"Other/Additional Provisions".

          Interest on this Note will accrue from, and including, the immediately
preceding Interest Payment Date to which interest has been paid or duly provided
for (or from, and including, the Original Issue Date if no interest has been
paid or duly provided for) to, but excluding, the applicable Interest Payment
Date or the Maturity Date, as the case may be (each, an "Interest Period"). The
interest so payable, and punctually paid or duly provided for, on any Interest
Payment Date will, subject to certain exceptions described herein, be paid to
the person in whose name this Note (or one or more predecessor Notes) is
registered at the close of business on the fifteenth calendar day (whether or
not a Business Day, as defined below) immediately preceding such Interest
Payment Date (the "Record Date"); provided, however, that interest payable on
the Maturity Date will be payable to the person to whom the principal hereof and
premium, if any, hereon shall be payable. Any such interest not so punctually
paid or duly provided for ("Defaulted Interest") will forthwith cease to be
payable to the holder on any Record Date, and shall be paid to the person in
whose name this Note is registered at the close of business on a special record
date (the "Special Record Date") for the payment of such Defaulted Interest to
be fixed by the Trustee hereinafter referred

                                       3
<PAGE>
 
to, notice whereof shall be given to the holder of this Note by the Trustee not
less than 15 calendar days prior to such Special Record Date or may be paid at
any time in any other lawful manner not inconsistent with the requirements of
any securities exchange on which this note may be listed, and upon such notice
as may be required by such exchange, all as more fully provided for in the
Indenture.

          Payment of principal, premium, if any, and interest in respect of this
Note due on the Maturity Date will be made in immediately available funds upon
presentation and surrender of this Note (and, with respect to any applicable
repayment of this Note, a duly completed election form as contemplated on the
reverse hereof) at the corporate trust office of the Trustee maintained for
that purpose in the Borough of Manhattan, The City of New York, currently
located at [ADDRESS], New York, New York [ZIP CODE], or at such other paying
agency in the Borough of Manhattan, The City of New York, as the Company may
determine; provided, however, that if such payment is to be made in a Specified
Currency other than United States dollars as set forth below, such payment will
be made by wire transfer of immediately available funds to an account with a
bank designated by the holder hereof at least 16 calendar days prior to the
Maturity Date, provided that such bank has appropriate facilities therefor and
that this Note (and, if applicable, a duly completed repayment election form) is
presented and surrendered at the aforementioned office of the Trustee in
time for the Trustee to make such payment in such funds in accordance with
its normal procedures. Payment of interest due on any Interest Payment Date
other than the Maturity Date will be made by check mailed to the address of the
person entitled thereto as such address shall appear in the Security Register
maintained at the aforementioned office of the Trustee; provided, however,
that a holder of U.S.$10,000,000 (or, if the Specified Currency specified above
is other than United States dollars, the equivalent thereof in the Specified
Currency) or more in aggregate principal amount of Notes (whether having
identical or different terms and provisions) will be entitled to receive
interest payments on such Interest Payment Date by wire transfer of immediately
available funds if appropriate wire transfer instructions have been received in
writing by the Trustee not less than 16 calendar days prior to such
Interest Payment Date. Any such wire transfer instructions received by the
Trustee shall remain in effect until revoked by such holder.

          If any Interest Payment Date or the Maturity Date falls on a day that
is not a Business Day, the required payment of principal, premium, if any,
and/or interest shall be made on the next succeeding Business Day with the same
force and effect as if made on the date such payment was due, and no interest
shall accrue with respect to such payment for the period from and after such
Interest Payment Date or the Maturity Date, as the case may be, to the date of
such payment on the next succeeding Business Day.

          As used herein, "Business Day" means any day, other than a Saturday or
Sunday, that is neither a legal holiday nor a day on which banking institutions
are authorized or required by law or executive order to close in The City of New
York; provided, however, that if the Specified Currency is other than United
States dollars and any payment is to be made in the Specified Currency in
accordance with the provisions hereof, such day is also not a day on which
banking institutions are authorized or required by law or executive order to
close in the Principal Financial Center (as defined below) of the country
issuing the Specified Currency (or, in the case of European Currency Units
("ECU"), is not a day that appears as an ECU non-settlement day on the display
designated as "ISDE" on the Reuter Monitor Money Rates Service (or a day so
designated by the ECU Banking Association) or, if ECU non-settlement days do not
appear on that page (and are not so designated), is not a day on which payments
in ECU cannot be settled in the international interbank market). "Principal
Financial Center" means the capital city of the country issuing the Specified
Currency, except that with respect to United States dollars, Australian dollars,
Deutsche marks, Dutch guilders, Italian lire, Swiss francs and ECU, the
"Principal Financial Center" shall be The City of New York, Sydney, Frankfurt,
Amsterdam, Milan, Zurich and Luxembourg, respectively.

          The Company is obligated to make payment of principal, premium, if
any, and interest in respect of this Note in the Specified Currency (or, if the
Specified Currency is not at the time of such payment legal tender for the
payment of public and private debts, in such other coin or currency of the
country which issued the Specified Currency as at the time of such payment is
legal tender for the payment of such debts). If the Specified Currency is other
than United States dollars, any such amounts so payable by the Company will be
converted by the Exchange Rate Agent specified above into United States dollars
for payment to the holder of this Note; provided, however, that the holder of
this Note may elect to receive such amounts in such Specified Currency pursuant
to the provisions set forth below.

          If the Specified Currency is other than United States dollars and the
holder of this Note shall not have duly made an election to receive all or a
specified portion of any payment of principal, premium, if any, and/or interest
in respect of this Note in the Specified Currency, any United States dollar
amount to be received by the holder of this Note will be based on the highest
bid quotation in The City of New York received by the Exchange Rate Agent at
approximately 11:00 A.M., New York City time, on the second Business Day
preceding the applicable payment date from three recognized foreign exchange
dealers (one of whom may be the Exchange Rate Agent) selected by the Exchange
Rate Agent and approved by the Company for the purchase by the quoting dealer of
the Specified Currency for United States dollars for settlement on such payment
date in the aggregate amount of the Specified Currency payable to all holders of
Notes scheduled to receive United States

                                       5

dollar payments and at which the applicable dealer commits to execute a
contract. All currency exchange costs will be borne by the holder of this Note
by deductions from such payments. If three such bid quotations are not
available, payments on this Note will be made in the Specified Currency.

          If the Specified Currency is other than United States dollars, the
holder of this Note may elect to receive all or a specified portion of any
payment of principal, premium, if any, and/or interest in respect of this Note
in the Specified Currency by submitting a written request for such payment to
the Trustee at its corporate trust office in The City of New York on or
prior to the applicable Record Date or at least 16 calendar days prior to the
Maturity Date, as the case may be. Such written request may be mailed or hand
delivered or sent by cable, telex or other form of facsimile transmission. The
holder of this Note may elect to receive all or a specified portion of all
future payments in the Specified Currency in respect of such principal, premium,
if any, and/or interest and need not file a separate election for each payment.
Such election will remain in effect until revoked by written notice to the
Trustee, but written notice of any such revocation must be received by the
Trustee on or prior to the applicable Record Date or at least 16 calendar
days prior to the Maturity Date, as the case may be.

          If the Specified Currency is other than United States dollars or a
composite currency and the holder of this Note shall have duly made an election
to receive all or a specified portion of any payment of principal, premium, if
any, and/or interest in respect of this Note in the Specified Currency and if
the Specified Currency is not available due to the imposition of exchange
controls or other circumstances beyond the control of the Company, the Company
will be entitled to satisfy its obligations to the holder of this Note by making
such payment in United States dollars on the basis of the Market Exchange Rate
(as defined below) on the second Business Day prior to such payment date or, if
such Market Exchange Rate is not then available, on the basis of the most
recently available Market Exchange Rate or as otherwise specified on the face
hereof. The "Market Exchange Rate" for the Specified Currency means the noon
dollar buying rate in The City of New York for cable transfers for the Specified
Currency as certified for customs purposes by (or if not so certified, as
otherwise determined by) the Federal Reserve Bank of New York. Any payment made
under such circumstances in United States dollars will not constitute an Event
of Default (as defined in the Indenture).

          If the Specified Currency is a composite currency and the holder of
this Note shall have duly made an election to receive all or a specified portion
of any payment of principal, premium, if any, and/or interest in respect of this
Note in the Specified Currency and if such composite currency is unavailable due
to the imposition of exchange controls or other circumstances beyond the control
of the Company, then the Company will be entitled to

                                       6

<PAGE>
 
satisfy its obligations to the holder of this Note by making such payment in
United States dollars. The amount of each payment in United States dollars shall
be computed by the Exchange Rate Agent on the basis of the equivalent of the
composite currency in United States dollars. The component currencies of the
composite currency for this purpose (collectively, the "Component Currencies"
and each, a "Component Currency") shall be the currency amounts that were
components of the composite currency as of the last day on which the composite
currency was used. The equivalent of the composite currency in United States
dollars shall be calculated by aggregating the United States dollar equivalents
of the Component Currencies. The United States dollar equivalent of each of the
Component Currencies shall be determined by the Company or the Exchange Rate
Agent on the basis of the most recently available Market Exchange Rate for each
such Component Currency, or as otherwise specified on the face hereof.

          If the official unit of any Component Currency is altered by way of
combination or subdivision, the number of units of the currency as a Component
Currency shall be divided or multiplied in the same proportion. If two or more
Component Currencies are consolidated into a single currency, the amounts of
those currencies as Component Currencies shall be replaced by an amount in such
single currency equal to the sum of the amounts of the consolidated Component
Currencies expressed in such single currency. If any Component Currency is
divided into two or more currencies, the amount of the original Component
Currency shall be replaced by the amounts of such two or more currencies, the
sum of which shall be equal to the amount of the original Component Currency.

          All determinations referred to above made by the Company or its agent
(including the Exchange Rate Agent) shall be at its sole discretion and shall,
in the absence of manifest error, be conclusive for all purposes and binding on
the holder of this Note.

          Reference is hereby made to the further provisions of this Note set
forth on the reverse hereof and, if so specified above, in the Addendum hereto,
which further provisions shall have the same force and effect as if set forth on
the face hereof.

          Unless the Certificate of Authentication hereon has been executed by
the Trustee by manual signature, this Note shall not be entitled to any benefit
under the Indenture or be valid or obligatory for any purpose.

                                TRIBUNE COMPANY
                                MEDIUM-TERM NOTE
                                  (Fixed Rate)


          This Note is one of a duly authorized series of Debt Securities (the
"Debt Securities") of the Company issued and to be issued under an Indenture,
dated as of March 1, 1992, as amended, modified or supplemented from time to
time (the "Indenture"), between the Company and First Trust of Illinois,
National Association, as successor Trustee (the "Trustee", which term includes
any successor trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Trustee and the holders of the Debt Securities, and of the
terms upon which the Debt Securities are, and are to be, authenticated and
delivered.  This Note is one of the series of Debt Securities designated as
"Medium-Term Notes Due Nine Months or More From Date of Issue" (the "Notes").
All terms used but not defined in this Note specified on the face hereof or in
an Addendum hereto shall have the meanings assigned to such terms in the
Indenture.

          This Note is issuable only in registered form without coupons in
minimum denominations of U.S.$1,000 and integral multiples thereof or the
minimum Authorized Denomination specified on the face hereof.

          This Note will not be subject to any sinking fund and, unless
otherwise provided on the face hereof in accordance with the provisions of the
following two paragraphs, will not be redeemable or repayable prior to the
Stated Maturity Date.

          This Note will be subject to redemption at the option of the Company
on any date on or after the Initial Redemption Date, if any, specified on the
face hereof, in whole or from time to time in part in increments of U.S.$1,000
or the minimum Authorized Denomination (provided that any remaining principal
amount hereof shall be at least U.S.$1,000 or such minimum Authorized
Denomination), at the Redemption Price (as defined below), together with unpaid
interest accrued thereon to the date fixed for redemption (each, a "Redemption
Date"), on notice given no more than 60 nor less than 30 calendar days prior to
the Redemption Date and in accordance with the provisions of the Indenture.  The
"Redemption Price" shall initially be the Initial Redemption Percentage
specified on the face hereof multiplied by the unpaid principal amount of this
Note to be redeemed.  The Initial Redemption Percentage shall decline at each
anniversary of the Initial Redemption Date by the Annual Redemption Percentage
Reduction, if any, specified on the face hereof until the Redemp tion Price is
100% of unpaid principal amount to be redeemed.  In

                                       9
<PAGE>
 
the event of redemption of this Note in part only, a new Note of like tenor for
the unredeemed portion hereof and otherwise having the same terms as this Note
shall be issued in the name of the holder hereof upon the presentation and
surrender hereof.

          This Note will be subject to repayment by the Company at the option of
the holder hereof on the Optional Repayment Date(s), if any, specified on the
face hereof, in whole or in part in increments of U.S.$1,000 or the minimum
Authorized Denomination (provided that any remaining principal amount hereof
shall be at least U.S.$1,000 or such minimum Authorized Denomination), at a
repayment price equal to 100% of the unpaid principal amount to be repaid,
together with unpaid interest accrued thereon to the date fixed for repayment
(each, a "Repayment Date").  For this Note to be repaid, this Note must be
received, together with the form hereon entitled "Option to Elect Repayment"
duly completed, by the Trustee at its corporate trust office not more than 60
nor less than 30 calendar days prior to the Repayment Date.  Exercise of such
repayment option by the holder hereof will be irrevocable.  In the event of
repayment of this Note in part only, a new Note of like tenor for the unrepaid
portion hereof and otherwise having the same terms as this Note shall be issued
in the name of the holder hereof upon the presentation and surrender hereof.

          If this Note is an Original Issue Discount Note as specified on the
face hereof, the amount payable to the holder of this Note in the event of
redemption, repayment or acceleration of maturity will be equal to the sum of
(1) the Issue Price specified on the face hereof (increased by any accruals of
the Discount, as defined below) and, in the event of any redemption of this Note
(if applicable), multiplied by the Initial Redemption Percentage (as adjusted by
the Annual Redemption Percentage Reduction, if applicable) and (2) any unpaid
interest on this Note accrued from the Original Issue Date to the Redemption
Date, Repayment Date or date of acceleration of maturity, as the case may be.
The difference between the Issue Price and 100% of the principal amount of this
Note is referred to herein as the "Discount".

          For purposes of determining the amount of Discount that has accrued as
of any Redemption Date, Repayment Date or date of acceleration of maturity of
this Note, such Discount will be accrued so as to cause the yield on the Note to
be constant.  The constant yield will be calculated using a 30-day month, 360-
day year convention, a compounding period that, except for the Initial Period
(as defined below), corresponds to the shortest period between Interest Payment
Dates (with ratable accruals within a compounding period) and an assumption that
the maturity of this Note will not be accelerated.  If the period from the
Original Issue Date to the initial Interest Payment Date (the "Initial Period")
is shorter than the compounding period for this Note, a proportionate amount of
the yield for an entire compounding period will be accrued.  If the Initial
Period is longer than the compounding period, then such period will be divided
into a regular

                                      10
<PAGE>
 
compounding period and a short period, with the short period being treated as
provided in the preceding sentence.

          If an Event of Default, as defined in the Indenture, shall occur and
be continuing, the principal of the Notes may be declared due and payable in the
manner and with the effect provided in the Indenture.

          The Indenture contains provisions for defeasance of (i) the entire
indebtedness of the Notes or (ii) certain covenants and Events of Default with
respect to the Notes, in each case upon compliance with certain conditions set
forth therein, which provisions apply to the Notes.

          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the holders of the Debt Securities at any time by the
Company and the Trustee with the consent of the holders of not less than a
majority of the aggregate principal amount of all Debt Securities at the time
outstanding and affected thereby.  The Indenture also contains provisions
permitting the holders of not less than a majority of the aggregate principal
amount of the outstanding Debt Securities of any series, on behalf of the
holders of all such Debt Securities, to waive compliance by the Company with
certain provisions of the Indenture.  Furthermore, provisions in the Indenture
permit the holders of not less than a majority of the aggregate principal amount
of the outstanding Debt Securities of any series, in certain instances, to
waive, on behalf of all of the holders of Debt Securities of such series,
certain past defaults under the Indenture and their consequences.  Any such
consent or waiver by the holder of this Note shall be conclusive and binding
upon such holder and upon all future holders of this Note and other Notes issued
upon the registration of transfer hereof or in exchange heretofore or in lieu
hereof, whether or not notation of such consent or waiver is made upon this
Note.

          No reference herein to the Indenture and no provision of this Note or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay principal, premium, if any, and interest in
respect of this Note at the times, places and rate or formula, and in the coin
or currency, herein prescribed.

          As provided in the Indenture and subject to certain limitations
therein and herein set forth, the transfer of this Note is registrable in the
Security Register of the Company upon surrender of this Note for registration of
transfer at the office or agency of the Company in any place where the principal
hereof and any premium or interest hereon 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 by his
attorney duly authorized

                                      11
<PAGE>
 
in writing, and thereupon one or more new Notes, of authorized denominations and
for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

          As provided in the Indenture and subject to certain limitations
therein and herein set forth, this Note is exchangeable for a like aggregate
principal amount of Notes of different authorized denominations but otherwise
having the same terms and conditions, as requested by the holder hereof
surrendering the same.

          No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

          Prior to due presentment of this Note for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the holder in whose name this Note is registered as the owner thereof for all
purposes, whether or not this Note be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

          The Indenture and this Note shall be governed by and construed in
accordance with the laws of the State of Illinois applicable to agreements made
and to be performed entirely in such State.

          Re:  Registration Statement on Form S-3
               $500,000,000 Aggregate Initial Public
               Offering Price of Debt Securities and
               Warrants to Purchase Debt Securities
               -------------------------------------

Ladies and Gentlemen:

          We refer to the Registration Statement on Form S-3 (the "Registration
Statement") being filed by Tribune Company (the "Company") with the Securities
and Exchange Commission (the "SEC") under the Securities Act of 1933, as amended
(the "Securities Act"), relating to the shelf registration of $500,000,000
aggregate initial public offering price of the Company's debt securities (the
"Debt Securities") and warrants to purchase Debt Securities (the "Warrants").
The Debt Securities are to be issued under the Indenture, dated as of March 1,
1992 (the "Indenture"), between the Company and First Trust of Illinois,
National Association, as successor trustee (the "Trustee").  The Warrants are to
be issued under a Warrant Agreement, the form of which was filed as Exhibit 4.3
to the Company's Registration Statement on Form S-3, Registration No. 33-45793
(a "Warrant Agreement").

          We are familiar with the proceedings to date with respect to the
proposed issuance and sale of the Debt Securities and the Warrants and have
examined such records, documents and questions of law, and satisfied ourselves
as to such matters of fact, as we have considered relevant and necessary as a
basis for this opinion.

          Based on the foregoing, we are of the option that:

          1.  Each series of Debt Securities will be legally issued and binding
     obligations of the Company (except to the extent enforceability may be
     limited by applicable bankruptcy, insolvency, reorganization, moratorium,
     fraudulent transfer or other similar laws affecting the enforcement of
     creditors' rights generally and by the effect of general principles of
     equity, regardless of whether enforceability is considered in a proceeding
     in equity or at law) when (i) the Registration Statement, as finally
     amended (including any necessary post-effective amendments), shall have
     become effective under the Securities Act; (ii) a Prospectus Supplement
     (including any Pricing Supplement) with respect to such series of Debt
     Securities shall have been filed with the SEC pursuant to Rule 424 under
     the Securities Act; (iii) the Company's Board of Directors or a duly
     authorized committee thereof shall have duly adopted final resolutions
