                          FORWARD-LOOKING INFORMATION

     This Prospectus includes "forward-looking statements" within the meaning of
the Private Securities Litigation Reform Act of 1995 (the "PSLRA"). The PSLRA
provides a "safe harbor" for such statements to encourage companies to provide
prospective information about themselves so long as such information is
identified as forward-looking and is accompanied by meaningful cautionary
statements identifying important factors that could cause actual results to
differ materially from those projected in the information. All statements other
than statements of historical fact made in this Prospectus or incorporated by
reference are forward-looking. In particular, the statements regarding industry
prospects and our future results of operations or financial position are
forward-looking statements. Forward-looking statements represent management's
current expectations and are inherently uncertain. Investors are warned that our
actual results may differ significantly from management's expectations and,
therefore, from the results discussed in such forward-looking statements.
Factors that might cause such differences include, but are not limited to, the
factors described in the prospectus supplement.

                         DESCRIPTION OF DEBT SECURITIES

     The following description of the terms of the debt securities describes
general terms that apply to the debt securities. The particular terms of any
debt securities will be described more specifically in each prospectus
supplement (and pricing supplement, where applicable) relating to those debt
securities.

     The debt securities will be issued under an indenture dated as of
            , 2000, between us and The Chase Manhattan Bank, as trustee.

                                        3
<PAGE>   5

     We summarize the indenture below. Since this is only a summary, it does not
contain all of the information that may be important to you. A copy of the
entire indenture is an exhibit to the registration statement of which this
prospectus is a part. When we make parenthetical section references in this
prospectus, those are references to sections of the indenture. We incorporate
the entire indenture by reference, and encourage you to read the indenture.

GENERAL

     The indenture does not limit the aggregate principal amount of debt
securities we may issue and provides that we may issue debt securities
thereunder from time to time in one or more series. (Section 3.1) The indenture
does not limit the amount of other indebtedness or debt securities, other than
certain secured indebtedness as described below, which we or our subsidiaries
may issue. Under the indenture, the terms of the debt securities of any series
may differ and we, without the consent of the holders of the debt securities of
any series, may reopen a previous series of debt securities and issue additional
debt securities of the series or establish additional terms of the series.
(Section 3.1)

     Unless otherwise provided in a prospectus supplement, the debt securities
will be our unsecured obligations and will rank equally with all of our other
unsecured and unsubordinated indebtedness.

     Because we are a holding company, our rights and the rights of our
creditors (including the holders of debt securities) and stockholders to
participate in any distribution of assets of any subsidiary upon the
subsidiary's liquidation or reorganization or otherwise would be subject to the
prior claims of the subsidiary's creditors, except to the extent that we may be
a creditor with recognized claims against the subsidiary. The right of our
creditors (including the holders of debt securities) to participate in the
distribution of stock owned by us in certain of our subsidiaries, including our
insurance subsidiaries, may also be subject to approval by certain insurance
regulatory authorities having jurisdiction over such subsidiaries.

     Each prospectus supplement will describe the following terms of the debt
securities offered by it:

     - the title of the debt securities;

     - any limit on the aggregate principal amount of the debt securities or the
       series of which they are a part;

     - the currency or currencies, or composite currencies, in which the debt
       securities will be denominated and in which we will make payments on the
       debt securities;

     - the date or dates on which we must pay principal;

     - the rate or rates at which the debt securities will bear interest or the
       manner in which interest will be determined, if any interest is payable;

     - the date or dates from which any interest will accrue, the date or dates
       on which we must pay interest and the record date for determining who is
       entitled to any interest payment;

     - the place or places where we must pay the debt securities and where any
       debt securities issued in registered form may be sent for transfer or
       exchange;

     - the terms and conditions on which we may, or may be required to, redeem
       the debt securities;

     - the terms and conditions of any sinking fund;

     - if other than denominations of $1,000, the denominations in which we may
       issue the debt securities;

     - the amount we will pay if the maturity of the debt securities is
       accelerated;

                                        4
<PAGE>   6

     - whether we will issue the debt securities in the form of one or more
       global securities and, if so, the identity of the depositary for the
       global security or securities;

     - any addition to or changes in the events of default or covenants that
       apply to the debt securities;

     - whether the debt securities will be defeasible; and

     - any other terms of the debt securities and any other deletions from or
       modifications or additions to the indenture in respect of the debt
       securities. (Section 3.1)

     Unless otherwise stated in the prospectus supplement, we will pay
principal, premium, interest and additional amounts, if any, on the debt
securities at the office or agency we maintain for that purpose (initially the
corporate trust office of the trustee). We may pay interest on debt securities
issued in registered form by check mailed to the address of the persons entitled
to the payments or we may pay by transfer to their U.S. bank accounts. Interest
on debt securities issued in registered form will be payable on any interest
payment date to the registered owners of the debt securities at the close of
business on the regular record date for the interest payment date. We will name
in the prospectus supplement all paying agents we initially designate for the
debt securities. We may designate additional paying agents, rescind the
designation of any paying agent or approve a change in the office through which
any paying agent acts, but we must maintain a paying agent in each place where
payments on the debt securities are payable. (Sections 3.7 and 10.2)

     Unless otherwise stated in the prospectus supplement, the debt securities
may be presented for transfer (duly endorsed or accompanied by a written
instrument of transfer, if we or the security registrar require) or exchanged
for other debt securities of the same series (containing identical terms and
provisions, in any authorized denominations, and in the same aggregate principal
amount) at the office or agency we maintain for that purpose (initially the
corporate trust office of the trustee). There will be no service charge for any
transfer or exchange, but we may require payment sufficient to cover any tax or
other governmental charge or expenses payable in connection with the transfer or
exchange. We will not be required to (1) issue, register the transfer of, or
exchange, debt securities during a period beginning at the opening of business
15 days before the day of mailing of a notice of redemption of any such debt
securities and ending at the close of business on the day of such mailing or (2)
register the transfer of or exchange any debt security selected for redemption
in whole or in part, except the unredeemed portion of any debt security being
redeemed in part. (Section 3.5) We have appointed the trustee as security
registrar. Any transfer agent (in addition to the security registrar) we
initially designate for any debt securities will be named in the related
prospectus supplement. We may designate additional transfer agents, rescind the
designation of any transfer agent or approve a change in the office through
which any transfer agent acts, but we must maintain a transfer agent in each
place where any payments on the debt securities are payable. (Section 10.2)

     Unless otherwise stated in the prospectus supplement, we will issue the
debt securities only in fully registered form, without coupons, in minimum
denominations of $1,000 and integral multiples of $1,000. (Section 3.2) The debt
securities may be represented in whole or in part by one or more global debt
securities. Each global security will be registered in the name of a depositary
or its nominee and the global security will bear a legend regarding the
restrictions on exchanges and registration of transfer. Interests in a global
security will be shown on records maintained by the depositary and its
participants, and transfers of those interests will be made as described below.

     We may issue the debt securities as original issue discount securities
(bearing no interest or bearing interest at a rate which at the time of issuance
is below market rates) to be sold at a substantial discount below their
principal amount. We will describe certain special U.S. federal income tax and
other considerations applicable to any debt securities that are issued as
original issue discount securities in the applicable prospectus supplement.

                                        5
<PAGE>   7

     If the purchase price of any debt securities is payable in one or more
foreign currencies or currency units, or if any debt securities are denominated
in one or more foreign currencies or currency units, or if any payments on the
debt securities are payable in one or more foreign currencies or currency units,
we will describe the restrictions, elections, certain U. S. federal income tax
considerations, specific terms and other information about the debt securities
and the foreign currency or currency units in the prospectus supplement.

     We will comply with Section 14(e) under the Exchange Act, and any other
tender offer rules under the Exchange Act that may then be applicable, in
connection with any obligation to purchase debt securities at the option of the
holders. Any such obligation applicable to a series of debt securities will be
described in the related prospectus supplement.

     Unless otherwise described in a prospectus supplement relating to any debt
securities, other than as described below under "-- Limitation on Mortgages and
Liens," the indenture does not limit our ability to incur debt or give holders
of debt securities protection in the event of a sudden and significant decline
in our credit quality or a takeover, recapitalization or highly leveraged or
similar transaction involving us. Accordingly, we could in the future enter into
transactions that could increase the amount of indebtedness outstanding at that
time or otherwise affect our capital structure or credit rating. You should
refer to the prospectus supplement relating to a particular series of debt
securities for information regarding any changes in the events of default
described below or covenants contained in the indenture, including any addition
of a covenant or other provisions providing event risk or similar protection.

GLOBAL SECURITIES

     The debt securities of a series may be issued in whole or in part in the
form of one or more global debt securities that will be deposited with a
depositary or its nominee identified in the series prospectus supplement.

     The specific terms of the depositary arrangement covering debt securities
will be described in the prospectus supplement relating to that series. We
anticipate that the following provisions will apply to all depositary
arrangements.

     Upon the issuance of a global security, the depositary for the global
security or its nominee will credit, to accounts in its book-entry registration
and transfer system, the principal amounts of the debt securities represented by
the global security. These accounts will be designated by the underwriters or
agents with respect to such debt securities or by us if such debt securities are
offered and sold directly by us. Only institutions that have accounts with the
depositary or its nominee, and persons who hold beneficial interests through
those participants, may own beneficial interests in a global security. Ownership
of beneficial interests in a global security will be shown only on, and the
transfer of those ownership interests will be effected only through, records
maintained by the depositary, its nominee or any such participants. The laws of
some states require that certain purchasers of securities take physical delivery
of such securities in definitive form. These laws may prevent you from
transferring your beneficial interest in a global security.

     As long as the depositary or its nominee is the registered owner of a
global security, the depositary or nominee will be considered the sole owner or
holder of the debt securities represented by the global security. Except as
described below, owners of beneficial interests in a global security will not be
entitled to have debt securities registered in their names and will not be
entitled to receive physical delivery of the debt securities in definitive form.

     We will make all payments of principal of, any premium and interest on, and
any additional amounts with respect to, debt securities issued as global
securities to the depositary or its nominee. Neither we nor the trustee, any
paying agent or the security registrar assume any responsibility or liability
for any aspect of the depositary's or any participant's records relating to, or
for payments made on account of, beneficial interests in a global security.

     We expect that the depositary for a series of debt securities or its
nominee, upon receipt of any payment with respect to such debt securities, will
credit immediately participants' accounts with payments in amounts proportionate
to their respective beneficial interest in the principal amount of the global
security for such debt securities as shown on the records of such depositary or
its nominee. We also expect 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.

     The indenture provides that if (1) the depositary notifies us that it is
unwilling or unable to continue as depositary for a series of debt securities,
or if the depositary is no longer legally qualified to serve in that capacity,
and we have not appointed a successor depositary within 90 days of written
notice, (2) we determine that a series of debt securities will no longer be
represented by global securities and we execute and deliver an order to that
effect to the trustee, or (3) an event of default with respect to a series of
debt securities occurs and continues, the global securities for that series will
be exchanged for registered debt securities in definitive form. The definitive
debt securities will be registered in the name or names the depositary instructs
the trustee. (Section 3.5) We expect that these instructions may be based upon
directions the depositary receives from participants with respect to ownership
of beneficial interests in global securities.

CERTAIN RESTRICTIONS

     Limitations on Mortgages and Liens. Neither we nor any of our restricted
subsidiaries (as defined below) will be permitted to issue, assume or guarantee
certain types of secured debt, without securing the debt securities on an equal
and ratable basis with any such debt. These limits apply to debt secured by
mortgages, pledges, liens and other encumbrances, which together we refer to as
liens. These limits will not apply to:

     - liens that existed on the date of the indenture;

     - liens on real estate (including liens that existed on property when we
       acquired it) not exceeding 100% of the fair value of the property at the
       time the debt is incurred;

     - liens arising from the acquisition of a business as a going concern or to
       which assets we acquire in satisfaction of secured debt are subject;

     - liens to secure extensions, renewals and replacements of debt secured by
       any of the liens referred to above, without increasing the amount of the
       debt; or

     - certain mechanics, landlords, tax or other statutory liens, including
       liens and deposits required or provided for under state insurance laws
       and similar regulatory statutes.

     Limitations on Sales of Capital Stock of Restricted Subsidiaries. Neither
we nor any of our restricted subsidiaries will be permitted to issue, sell,
transfer or dispose of (except to one of our restricted subsidiaries) capital
stock of a restricted subsidiary, unless we dispose of the entire capital stock
of the subsidiary at the same time for cash or property which, in the opinion of
our Board of Directors, is at least equal to the fair value of the capital
stock.

     For the purposes of the indenture, "restricted subsidiary" means a
subsidiary, including subsidiaries of any subsidiary, which meets any of the
following conditions:

          (1) Our and our other subsidiaries' investments in and advances to the
     subsidiary exceed 10% of our total consolidated assets as of the end of the
     most recently completed fiscal year;

                                        7
<PAGE>   9

          (2) Our and our other subsidiaries' proportionate share of the total
     assets (after inter-company eliminations) of the subsidiary exceeds 10% of
     our total consolidated assets as of the end of the most recently completed
     fiscal year; or

          (3) Our and our other subsidiaries' equity in the income from
     continuing operations before income taxes, extraordinary items and
     cumulative effect of a change in accounting principle of the subsidiary
     exceeds 10% of such income for us and our consolidated subsidiaries for the
     most recently completed fiscal year.

     For purposes of making the income test in clause (3) of the preceding
sentence, when a loss has been incurred by either us and our subsidiaries
consolidated or the tested subsidiary, but not both, the equity in the income or
loss of the tested subsidiary will be excluded from our consolidated income for
purposes of the computation and if our consolidated income for the most recent
fiscal year is at least 10% lower than the average of the income for the last
five fiscal years, the average income will be substituted for purposes of the
computation and any loss years will be omitted for purposes of computing average
income.

CONSOLIDATION, MERGER AND SALE OF ASSETS

     We may not consolidate with or merge into any other person or convey or
transfer or lease our properties and assets substantially as an entirety to any
person unless:

          (1) if we consolidate with or merge into another corporation or convey
     or transfer our properties and assets substantially as an entirety to any
     person, the successor is organized under the laws of the United States, or
     any state, and assumes our obligations under the debt securities;

          (2) immediately after the transaction, no event of default occurs and
     continues; and

          (3) we meet certain other conditions specified in the indenture.

MODIFICATION AND WAIVER

     We and the trustee may modify and amend the indenture with the consent of
the holders of a majority in aggregate principal amount of the outstanding debt
securities of each affected series. However, without the consent of each holder,
we cannot modify or amend the indenture in a way that would:

     - change the stated maturity of the principal of, or any installment of
       principal or interest on, any debt security;

     - reduce the principal or interest on any debt security;

     - change the place or currency of payment of principal or interest on any
       debt security;

     - impair the right to sue to enforce any payment on any debt security after
       it is due; or

     - reduce the percentage in principal amount of outstanding debt securities
       necessary to modify or amend the indenture, to waive compliance with
       certain provisions of the indenture or to waive certain defaults.

     The holders of a majority in aggregate principal amount of outstanding debt
securities may waive our compliance with certain restrictive covenants of the
indenture. The holders of a majority in principal amount of the outstanding debt
securities of any series may waive any past default under the indenture with
respect to outstanding debt securities of that series, which will be binding on
all holders of debt securities of that series, except a default in the payment
of principal or interest on any debt security of that series or in respect of a
provision of the indenture that cannot be modified or amended without each
holder's consent.

                                        8
<PAGE>   10

EVENTS OF DEFAULT

     Each of the following will be an event of default:

          (1) default for 30 days in the payment of any interest;

          (2) default in the payment of principal;

          (3) default in the performance of any other covenant in the indenture
     for 60 days after written notice;

          (4) a failure to pay when due or a default that results in the
     acceleration of maturity of any other debt of ours or our restricted
     subsidiaries in an aggregate amount of $25 million or more, unless (a) the
     acceleration is rescinded, stayed or annulled, or (b) the debt has been
     discharged or, in the case of debt we are contesting in good faith, we set
     aside a bond, letter of credit, escrow deposit or other cash equivalent
     sufficient to discharge the debt within 10 days after written notice of
     default is given to us; and

          (5) certain events in bankruptcy, insolvency or reorganization.

     We are required to furnish the trustee annually a statement as to our
fulfillment of our obligations under the indenture. The trustee may withhold
notice of any default to the holders of debt securities of any series (except a
default on principal or interest payments on debt securities of that series) if
it considers it in the interest of the holders to do so.

     If an event of default occurs and continues, either the trustee or the
holders of not less than 25% in principal amount of the outstanding debt
securities of the series in default may declare the principal amount immediately
due and payable by written notice to us (and to the trustee if given by the
holders). Upon any such declaration, the principal amount will become
immediately due and payable. However, the holders of a majority in principal
amount of the outstanding debt securities of that series may, under certain
circumstances, rescind and annul the acceleration.

     Except for certain duties in case of an event of default, the trustee is
not required to exercise any of its rights or powers at the request or direction
of any of the holders, unless the holders offer the trustee reasonable security
or indemnity. If the holders provide this security or indemnity, the holders of
a majority in principal amount of the outstanding debt securities of a series
may direct the time, method and place of conducting any proceeding for any
remedy available to the trustee, or exercising any trust or powers conferred on
the trustee with respect to the debt securities of that series.

     No holder of a debt security may bring any lawsuit or other proceeding with
respect to the indenture or for any remedy under the indenture, unless (a) the
holder first gives the trustee written notice of a continuing event of default,
(b) the holders of at least 25% in principal amount of the outstanding debt
securities of the series in default give the trustee a written request to bring
the proceeding and offer the trustee reasonable security or indemnity, (c) the
trustee fails to institute the proceeding within 60 days of the written request
and has not received from holders of a majority in principal amount of the
outstanding debt securities of the series in default a direction inconsistent
with that request. However, the holder of any debt security has the absolute
right to receive payment of the principal of and any interest on the debt
security on or after the stated due dates and to take any action to enforce any
such payment.

DISCHARGE, DEFEASANCE AND COVENANT DEFEASANCE

     We may discharge certain obligations to holders of any series of debt
securities that have not already been delivered to the trustee for cancellation
and that either have become due and payable or will become due and payable
within one year (or scheduled for redemption within one year) by depositing with
the trustee, in trust, funds in U.S. dollars or in the foreign currency in which
such debt securities are payable in an amount sufficient to pay the principal
and any premium, interest and additional amounts on such

                                        9
<PAGE>   11

debt securities to the date of deposit (if the debt securities have become due
and payable) or to the maturity date, as the case may be. (Section 4.1)

     Unless a prospectus supplement states that the following provisions do not
apply to the debt securities of that series, we may elect either (1) to defease
and be discharged from any and all obligations with respect to such debt
securities (except for, among other things, the obligation to pay additional
amounts, if any, upon the occurrence of certain events of taxation, assessment
or governmental charge with respect to payments on the debt securities and other
obligations to register the transfer or exchange of such debt securities, to
replace temporary or mutilated, destroyed, lost or stolen debt securities, to
maintain an office or agency with respect to such debt securities and to hold
moneys for payment in trust) ("defeasance") or (2) to be released from our
obligations under the indenture with respect to the debt securities under
certain covenants as described in the prospectus supplement, and our failure to
comply with these obligations will not constitute an event of default with
respect to such debt securities ("covenant defeasance"). Defeasance or covenant
defeasance is conditioned on our irrevocable deposit with the trustee, in trust,
of an amount in cash or government securities, or both, sufficient to pay the
principal of, any premium and interest on, and any additional amounts with
respect to, the debt securities on the scheduled due dates. (Section 4.2)

     Such a trust may be established only if, among other things, (1) the
applicable defeasance or covenant defeasance does not result in a breach or
violation of, or constitute a default under, the indenture or any other material
agreement or instrument to which we are a party or by which we are bound, (2) no
event of default has occurred and continues on the date the trust is established
and, with respect to defeasance only, at any time during the period ending on
the 123rd day after that date and (3) we have delivered to the trustee an
opinion of counsel to the effect that the holders of such debt securities will
not recognize income, gain or loss for U. S. federal income tax purposes as a
result of the defeasance or covenant defeasance and will be subject to U. S.
federal income tax on the same amounts, in the same manner and at the same times
as would have been the case if the defeasance or covenant defeasance had not
occurred. This opinion, in the case of defeasance, must refer to and be based
upon a letter ruling we have received from the Internal Revenue Service, a
Revenue Ruling published by the Internal Revenue Service or a change in
applicable U. S. federal income tax law occurring after the date of the
indenture. (Section 4.2)

GOVERNING LAW

     The indenture and the debt securities are governed by and will be
interpreted under the laws of the State of New York.

INFORMATION CONCERNING THE TRUSTEE

     Subject to the provisions of the Trust Indenture Act of 1939, as amended,
the trustee is under no obligation to exercise any of the powers vested in it by
the indenture at the request of any holder of debt securities unless the holder
offers the trustee reasonable indemnity against the costs, expenses and
liabilities which might result. The trustee is not required to expend or risk
its own funds or otherwise incur personal financial liability in performing its
duties if the trustee reasonably believes that it is not reasonably assured of
repayment or adequate indemnity.

     The Chase Manhattan Bank acts as property trustee for SAFECO Capital Trust
I (the issuer of our 8.072% Capital Securities) and for the 8.072% Capital
Securities and the underlying junior subordinated deferrable interest debentures
as well as the related indenture and guarantees. Chase Manhattan Delaware, an
affiliate of The Chase Manhattan Bank, acts as Delaware trustee for SAFECO
Capital Trust I. The Chase Manhattan Bank is also the trustee for our 7.875%
Notes due 2005 and 6.875% Notes due 2007 and our medium term note program, the
custodian for our life companies' investment portfolios, a lender under our bank
revolving credit line and a dealer under our commercial paper program. In
addition, we and our subsidiaries maintain various depository and disbursement
accounts with The Chase Manhattan Bank.

                              PLAN OF DISTRIBUTION

     We may sell debt securities (1) through agents, (2) to or through
underwriters, (3) through dealers, or (4) directly to purchasers. The prospectus
supplement will state the terms of the offering of the debt securities,
including the name or names of any underwriters, dealers or agents; the purchase
price of the debt securities and the proceeds we will receive from the sale; any
underwriting discounts and commissions and other items constituting
underwriters' compensation; any initial public offering price, any discounts or
concessions allowed or reallowed or paid to dealers, and any securities exchange
on which the debt securities may be listed. The initial public offering price,
discounts or concessions allowed or reallowed or paid to dealers may be changed
from time to time.

     We may offer the debt securities in one or more transactions at a fixed
price or prices, which we may change, at market prices prevailing at the time of
sale, at prices related to such prevailing market prices or at negotiated
prices.

     We may authorize agents to solicit offers to purchase debt securities from
time to time. We will identify any agent who offers or sells debt securities
described in this prospectus, and we will describe any commissions payable by us
to the agent, in the prospectus supplement. Unless otherwise indicated in such
prospectus supplement, any such agent will be acting on a reasonable best
efforts basis for the period of its appointment. Any such agent may be deemed to
be an underwriter, as that term is defined in the Securities Act, of the debt
securities so offered and sold.

     If debt securities are sold by means of an underwritten offering, we will
execute an underwriting agreement with an underwriter or underwriters, and the
names of the specific managing underwriter or underwriters, as well as any other
underwriters, and the terms of the transaction, including commissions, discounts
and any other compensation of the underwriters and dealers, if any, will be
stated in the prospectus supplement used by the underwriters to resell the debt
securities. If we use underwriters to sell debt securities, the underwriters
will purchase the debt securities for their own account and the underwriters may
resell such debt securities from time to time in one or more transactions,
including negotiated transactions, at fixed public offering prices or at varying
prices determined by the underwriters at the time of sale. Debt securities may
be offered to the public either through underwriting syndicates represented by
managing underwriters or directly by the managing underwriters. If we use any
underwriter or underwriters to sell the debt securities, unless otherwise
indicated in the prospectus supplement, the underwriters' obligations will be
conditioned on certain matters and the underwriters must purchase all the debt
securities of the offered series if they purchase any.

     If we use a dealer to sell the debt securities, we will sell such debt
securities to the dealer as principal. The dealer may then resell those debt
securities to the public at varying prices to be determined by the dealer at the
time of resale. Any such dealer may be deemed to be an underwriter, as that term
is defined in the Securities Act, of the debt securities it offers or sells. The
name of the dealer and the terms of the transaction will be stated in the
related prospectus supplement.

     We may directly solicit offers to purchase debt securities and we may sell
them directly to institutional investors or others, who, with respect to the
resale of those securities, may be deemed to be underwriters within the meaning
of the Securities Act. The terms of any direct sales will be described in the
related prospectus supplement.

     Agents, underwriters and dealers may be entitled under agreements with us
to be indemnified by us against certain civil liabilities, including liabilities
under the Securities Act that may arise from any untrue statement or alleged
untrue statement of a material fact or any omission or alleged omission to state
a material fact in this prospectus, any supplement or amendment hereto, or in
the registration statement of which this prospectus forms a part, or to
contribution with respect to payments which the agents, underwriters or dealers
may be required to make.

                                       11
<PAGE>   13

     If so indicated in the prospectus supplement, we will authorize
underwriters or other persons acting as our agents to solicit offers by certain
institutions to purchase debt securities from us pursuant to contracts providing
for payments and delivery on a future date. Institutions with which such
contracts may be made include commercial and savings banks, insurance companies,
pension funds, investment companies, educational and charitable institutions and
others, but in all cases we must approve such institutions. Purchaser
obligations will be subject to the condition that the purchase is not prohibited
under the laws of the jurisdiction to which the purchaser is subject at the time
the debt securities are delivered. The underwriters and other agents will not
have any responsibility for the validity or performance of these contracts.

     Each series of debt securities will be a new issue and will have no
established trading market. We may elect to list any series of debt securities
on an exchange but, unless otherwise stated in the applicable prospectus
supplement, we are not required to do so. You cannot be assured that there will
be a liquid trading market for any of the debt securities.

     Underwriters, dealers and agents may be customers of, engage in
transactions with, or perform services for, us and our subsidiaries in the
ordinary course of business.

                                 LEGAL OPINIONS

     The validity of the debt securities will be passed upon for us by Perkins
Coie LLP, Seattle, Washington. Perkins Coie LLP will rely on the opinion of
James W. Ruddy, our Senior Vice President and General Counsel, with respect to
certain matters. Certain legal matters will be passed upon for the underwriters,
dealers or agents, if any, by Mayer, Brown & Platt, Chicago, Illinois. Mayer,
Brown & Platt will rely on the opinion of Perkins Coie LLP with respect to
Washington law.

                              INDEPENDENT AUDITORS

     The consolidated financial statements and financial statement schedules of
SAFECO at December 31, 1998 and 1997, and for each of the three years in the
period ended December 31, 1998, incorporated by reference or included in the

Item 15. Indemnification of Officers and Directors.

         Sections 23B.08.500 through 23B.08.600 of the Washington Business
Corporation Act (the "WBCA") authorize a court to award, or a corporation's
board of directors to grant, indemnification to directors and officers on terms
sufficiently broad to permit indemnification under certain circumstances for
liabilities arising under the Securities Act of 1933, as amended (the
"Securities Act"). Article VII of the registrant's Bylaws, as amended (the
"Bylaws"), provides for indemnification of the registrant's directors, officers,
employees and agents to the maximum extent permitted by Washington law.

         Section 23B.08.320 of the WBCA authorizes a corporation to eliminate or
limit a director's personal liability to the corporation or its shareholders for
monetary damages for conduct as a director, except in certain circumstances
involving acts or omissions, intentional misconduct by a director or knowing
violations of law by a director or distributions illegal under Washington law,
or any transaction from which the director will personally receive a benefit in
money, property or services to which the director is not legally entitled.
Article VIII of the registrant's Restated Articles of Incorporation (the
"Articles of Incorporation") contains provisions implementing, to the fullest
extent permitted by Washington law, such limitations on a director's liability
to the registrant and its shareholders.

         Officers and directors of the registrant are covered by insurance (with
certain exceptions and certain limitations) that indemnifies them against losses
and liabilities arising from certain



                                      II-1
<PAGE>   15

alleged "wrongful acts," including alleged errors or misstatements, or certain
other alleged wrongful acts or omissions constituting neglect or breach of duty.

         The above discussion of the WBCA and the registrant's Bylaws and
Articles of Incorporation is not intended to be exhaustive and is qualified in
its entirety by reference to such statute, the Bylaws and the Articles of
Incorporation.

Item 17. Undertakings

         The undersigned registrant hereby undertakes:

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

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

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

                  (iii) To include any material information with respect to the
         plan of distribution not previously disclosed in the registration
         statement or any material change to such information in the
         registration statement;

         provided, however, that paragraphs (a)(i) and (a)(ii) do not apply if
         the information required to be included in a post-effective amendment
         by those paragraphs is contained in periodic reports filed with the
         Commission by the registrant pursuant to Section 13 or 15(d) of the
         Securities Exchange Act of 1934 that are incorporated by reference in
         the registration statement.

         (b) 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.

         (c) 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.

         The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of
SAFECO's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee



                                      II-3
<PAGE>   17

benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         The undersigned registrant hereby undertakes that:

         (a) For purposes of determining any liability under the Securities Act
of 1933, the information omitted from the form of prospectus filed as part of
this registration statement in reliance upon Rule 430A and contained in a form
of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
497(h) under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective; and

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

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers or persons controlling the
registrant pursuant to the provisions set forth or described in Item 15 of this
registration statement, or otherwise, the registrant has been informed that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act and is therefore
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by a registrant of expenses incurred or paid
by a director, officer or controlling person of such 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 Securities Act of 1933 and will be governed by the
final adjudication of such issue.

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

Ladies and Gentlemen:

        SAFECO Corporation, a corporation organized under the laws of the State
of Washington (the "Company"), proposes to sell to the several underwriters
named in Schedule II hereto (the "Underwriters"), for whom you (the
"Representatives") are acting as representatives, the principal amount of its
securities identified in Schedule I hereto (the "Securities"), to be issued
under an indenture (the "Indenture") to be dated as of ______, 2000, between the
Company and The Chase Manhattan Bank, as trustee (the "Trustee"). To the extent
there are no additional Underwriters listed on Schedule I other than you, the
term Representatives as used herein shall mean you, as Underwriters, and the
terms Representatives and Underwriters shall mean either the singular or plural
as the context requires. 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 Exchange Act
on or before the Effective Date of the Registration Statement 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 Effective Date of the Registration Statement 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. Certain
terms used herein are defined in Section 17 hereof.

        1. Representations and Warranties. The Company represents and warrants
to, and agrees with, each Underwriter as set forth below in this Section 1.

        (a) The Company meets the requirements for use of Form S-3 under the Act
and has prepared and filed with the Commission a registration statement (the
file number of which is set forth in Schedule I hereto) on Form S-3, including a
related basic prospectus, for registration under the Act of the offering and
sale of the Securities. The Company may have filed one or more amendments
thereto, including a Preliminary Final Prospectus, each of which has previously
been furnished to you. The Company will next file with the Commission one of the
following: (1) after the Effective Date of such registration statement, a final
prospectus supplement relating to the Securities in accordance



                                        1

<PAGE>   2

with Rules 430A and 424(b), (2) prior to the Effective Date of such registration
statement, an amendment to such registration statement (including the form of
final prospectus supplement) or (3) a final prospectus in accordance with Rules
415 and 424(b). In the case of clause (1), the Company has included in such
registration statement, as amended at the Effective Date, all information (other
than Rule 430A Information) required by the Act and the rules thereunder to be
included in such registration statement and the Final Prospectus. As filed, such
final prospectus supplement or such amendment and form of final prospectus
supplement shall contain all Rule 430A Information, together with all other such
required information, and, except to the extent the Representatives shall agree
in writing to a modification, shall be in all substantive respects in the form
furnished to you prior to the Execution Time or, to the extent not completed at
the Execution Time, shall contain only such specific additional information and
other changes (beyond that contained in the Basic Prospectus and any Preliminary
Final Prospectus) as the Company has advised you, prior to the Execution Time,
will be included or made therein. The Registration Statement, at the Execution
Time, meets the requirements set forth in Rule 415(a)(1)(x).

        (b) On the Effective Date, the Registration Statement did or will, and
when the Final Prospectus is first filed (if required) in accordance with Rule
424(b) and on the Closing Date (as defined herein), the Final Prospectus (and
any supplement thereto) will, comply in all material respects with the
applicable requirements of the Act, the Exchange Act and the Trust Indenture Act
and the respective rules thereunder; on the Effective Date and at the Execution
Time, the Registration Statement 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; on the Effective Date and on the Closing Date the Indenture did or
will comply in all material respects with the applicable requirements of the
Trust Indenture Act and the rules thereunder; and, on the Effective Date, the
Final Prospectus, if not filed pursuant to Rule 424(b), will not, and on the
date of any filing pursuant to Rule 424(b) and on the Closing Date, the Final
Prospectus (together with any supplement thereto) will not, include any untrue
statement of a material fact or omit to state a material fact necessary in order
to make the statements therein, in the light of the circumstances under which
they were made, not misleading; provided, however, that the Company makes no
representations or warranties as to (i) 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 (ii) the information contained in or omitted
from the Registration Statement or the Final Prospectus (or any 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 inclusion in the Registration Statement or the
Final Prospectus (or any supplement thereto).

        (c) The documents incorporated by reference in the Final Prospectus, at
the time they were or hereafter are filed with the Commission, complied or when
so filed will comply, as the case may be, in all material respects with the
requirements of the Exchange Act, and, when read together and with the other
information in the Final Prospectus, did not and will not include an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were or are made, not misleading.

corporation in good standing under the laws of the State of Washington, with
power and authority (corporate and other) to own its properties and conduct its
business as described in the Final Prospectus, and has been duly qualified as a
foreign corporation for the transaction of business and is in good standing (or
the local equivalent) under the laws of each other jurisdiction in which it owns
or leases properties or conducts any business so as to require such
qualification, or is subject to no material liability or disability by reason of
the failure to be so qualified in any such jurisdiction.

        (e) Each subsidiary of the Company that would constitute a "significant

Subsidiary" and collectively, the "Significant Subsidiaries") has been duly
organized and is validly existing as a corporation in good standing under the
laws of the jurisdiction of its incorporation, with power and authority
(corporate and other) to own its properties and conduct its business as
described in the Final Prospectus, and has been duly qualified as a foreign

subsidiaries free and clear of any perfected security interest or any other
security interests, claims, liens or encumbrances.

        (g) The financial statements and schedules of the Company and its
consolidated subsidiaries included or incorporated by reference in the Final
Prospectus and the Registration Statement present fairly in all material
respects the consolidated financial condition, results of operations and cash
flows of the Company and its consolidated subsidiaries as of the dates and for
the periods indicated, comply as to form with the applicable accounting
requirements of the Act or the Exchange Act, as applicable, and have been
prepared in conformity with generally accepted accounting principles applied on
a consistent basis throughout the periods involved (except as otherwise noted
therein).

        (h) Ernst & Young LLP, who have certified the financial statements
included or incorporated by reference in the Final Prospectus, are independent
public accountants as required by the Act.

        (i) No action, suit or proceeding by or before any court or governmental
agency, authority or body or any arbitrator involving the Company or any of its
subsidiaries or its or their property is pending or, to the best knowledge of
the Company, threatened that (i) could reasonably be expected to have a material
adverse effect on the Company's performance of its obligations under


                                        3

<PAGE>   4

this Agreement or the consummation of any of the transactions contemplated
hereby or (ii) could reasonably be expected to have a material adverse effect on
the condition (financial or otherwise), prospects, earnings, business or
properties of the Company and its subsidiaries, taken as a whole, whether or not
arising from transactions in the ordinary course of business, except as set
forth in or contemplated in the Final Prospectus (exclusive of any supplement
thereto).

        (j) Since the respective dates as of which information is given in the
Registration Statement and the Final Prospectus, except as may otherwise be
stated therein or contemplated thereby, there has been no material adverse
change, or any development involving a prospective material adverse change, in
the condition (financial or otherwise), earnings, business or properties of the
Company and its subsidiaries, taken as a whole, whether or not arising in the
ordinary course of business.

        (k) Each insurance company subsidiary of the Company (collectively, the
"Insurance Subsidiaries") is duly licensed as an insurance company in its
jurisdiction of organization and is duly licensed or authorized as an insurer in
each jurisdiction outside its jurisdiction of organization where it is required
to be so licensed or authorized to conduct its business as described in the
Registration Statement and the Final Prospectuses, except where the failure to
be so licensed or authorized would not result in a material adverse effect on
the condition (financial or otherwise), prospects, earnings, business or
properties of the Company and its subsidiaries, taken as a whole.

        (l) Each of the Company and each Insurance Subsidiary is in compliance
with the requirements of the insurance laws of the jurisdiction of its
incorporation or domicile and any applicable regulations thereunder and has
filed all reports, registrations, documents or other information required to be
filed thereunder, except where the failure to comply or file would not have a
material adverse effect on the condition (financial or otherwise), prospects,
earnings, business or properties of the Company and its subsidiaries, taken as a
whole; and each of the Insurance Subsidiaries is in compliance with the
insurance laws and regulations of each other jurisdiction that is applicable to
such Insurance Subsidiary, except where the failure to comply would not have a
material adverse effect on the condition (financial or otherwise), prospects,
earnings, business or properties of the Company and its subsidiaries, taken as a
whole.

        (m) All ceded reinsurance treaties, contracts, agreements and
arrangements to which the Company or any of its Insurance Subsidiaries is a
party are in full force and effect and neither the Company nor any of its
Insurance Subsidiaries is in violation of, or in default in the performance,
observance or fulfillment of, any obligation, agreement, covenant or condition
contained therein, except for such violations or defaults which could not
reasonably be expected, singly or in the aggregate, to have a material adverse
effect on the condition (financial or otherwise), prospects, earnings, business
or properties of the Company and its subsidiaries, taken as a whole; neither the
Company nor any of its Insurance Subsidiaries has received any notice from any
of the other parties to such treaties, contracts, agreements or arrangements
that such other party intends not to perform in any material respect its
obligations thereunder and none of them has any reason to believe that any of
the other parties to such treaties, contracts, agreements or arrangements will
be unable to perform


                                       4
<PAGE>   5

its obligations thereunder, except to the extent that (i) the Company or such
Insurance Subsidiary has established appropriate reserves on its financial
statements or (ii) such nonperformance could not reasonably be expected, singly
or in the aggregate, to have a material adverse effect on the condition
(financial or otherwise), prospects, earnings, business or properties of the
Company and its subsidiaries, taken as a whole.

        (n) The statutory annual and quarterly statements of the Insurance
Subsidiaries required to be filed and the statutory balance sheets and income
statements included in such statutory annual and quarterly statements, most
recently filed in each jurisdiction, have been prepared in conformity with
required or permitted statutory accounting principles or practices consistently
followed, except as may otherwise be indicated in the notes thereto and present
fairly the financial position of the Insurance Subsidiaries (on a statutory
basis) for the periods covered thereby.

        (o) This Agreement has been duly authorized, executed and delivered by
the Company.

        (p) The Indenture has been duly authorized, executed and delivered by
the Company and (assuming the due authorization, execution and delivery thereof
by the Trustee) is a valid and legally binding obligation of the Company
enforceable in accordance with its terms, except as enforcement thereof may be
limited by bankruptcy, insolvency, reorganization, moratorium or other laws
relating to or affecting enforcement of creditors' rights generally or by
general equity principles; and the Indenture has been duly qualified under the
Trust Indenture Act.

        (q) The Securities have been duly authorized for issuance, offer and
sale pursuant to this Agreement and, when issued, authenticated and delivered
pursuant to the provisions of this Agree ment and the Indenture against payment
of the consideration therefor specified in the Final Prospectus, the Securities
will constitute valid and legally binding obligations of the Company enforceable
in accordance with their terms, except as enforcement thereof may be limited by
bank ruptcy, insolvency, reorganization, moratorium or other laws relating to or
affecting enforcement of creditors' rights generally or by general equity
principles; and the Securities and the Indenture conform to the descriptions
thereof in the Final Prospectus.

        (r) The issue and sale of the Securities and the compliance by the
Company with all of the provisions of the Securities, the Indenture and this
Agreement and the consummation of the transactions herein and therein
contemplated will not conflict with or result in a breach or violation of any of
the terms or provisions of, or constitute a default under, any indenture,
mortgage, deed of trust, loan agreement or other agreement or instrument to
which the Company or any of its Significant Subsidiaries is a party or by which
the Company or any of its Significant Subsidiaries is bound or to which any of
the property or assets of the Company or any of its Significant Subsidiaries is
subject, nor will such action result in any violation of the provisions of the
charter or by-laws of the Company or any statute or any order, rule or
regulation of any court or governmental agency having jurisdiction over the
Company or any of its Significant Subsidiaries or any of their respective
properties; and no consent, approval, authorization, order or decree of any
court or governmental agency or body is required for the consummation by the
Company of the transactions contemplated



                                        5

by this Agreement or in connection with the sale of Securities hereunder, except
such as have been obtained or rendered, as the case may be, or as may be
required under state securities laws.

        (s) The Company is not and, after giving effect to the offering and sale
of the Securities and the application of the proceeds thereof as described in
the Final Prospectus, will not be an "investment company" as defined in the
Investment Company Act.

        Any certificate signed by any officer of the Company and delivered to
the Representatives or counsel for the Underwriters in connection with the
offering of the Securities shall be deemed a representation and warranty by the
Company, as to matters covered thereby, to each Underwriter.

        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 principal amount of the Securities set forth opposite such
Underwriter's name in Schedule II hereto.

        3. Delivery and Payment. Delivery of and payment for the Securities
shall be made on the date and at the time specified in Schedule I hereto or at
such time on such later date not more than three Business Days after the
foregoing date as the Representatives shall designate, which date and time may
be postponed by agreement between the Representatives and the Company or as
provided in Section 9 hereof (such date and time of delivery and payment for the
Securities being herein called the "Closing Date"). Delivery of the 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 wire transfer payable in same-day funds to an account specified by
the Company. Delivery of the Securities shall be made through the facilities of
The Depository Trust Company unless the Representatives shall otherwise
instruct.

        4. Offering by Underwriters. It is understood that the several
Underwriters propose to offer the Securities for sale to the public as set forth
in the Final Prospectus.

        5. Agreements. The Company agrees with the several Underwriters that:

        (a) The Company will use its best efforts to cause the Registration
Statement, if not effective at the Execution Time, and any amendment thereof, to
become effective. Prior to the termination of the offering of the Securities,
the Company will not file any amendment of the Registration Statement or
supplement (including the Final Prospectus or any Preliminary Final Prospectus)
to the Basic Prospectus or any Rule 462(b) Registration Statement unless the
Company



                                       6
<PAGE>   7

has furnished you a copy for your review prior to filing and will not
file any such proposed amendment or supplement to which you reasonably object.
Subject to the foregoing sentence, if the Registration Statement has become or
becomes effective pursuant to Rule 430A, or filing of the Final Prospectus is
otherwise required under Rule 424(b), the Company will cause the Final
Prospectus, properly completed, and any supplement thereto to be filed with the
Commission pursuant to the applicable paragraph of Rule 424(b) within the time
period prescribed and will provide evidence satisfactory to the Representatives
of such timely filing. The Company will promptly advise the Representatives (1)
when the Registration Statement, if not effective at the Execution Time, shall
have become effective, (2) when the Final Prospectus, and any supplement
thereto, shall have been filed (if required) with the Commission pursuant to
Rule 424(b) or when any Rule 462(b) Registration Statement shall have been filed
with the Commission, (3) when, prior to termination of the offering of the
Securities, any amendment to the Registration Statement shall have been filed or
become effective, (4) of any request by the Commission or its staff for any
amendment of the Registration Statement, or any Rule 462(b) Registration
Statement, or for any supplement to the Final Prospectus or for any additional
information, (5) 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 (6) of the receipt by the
Company of any notification with respect to the suspension of the qualification
of the Securities for sale in any jurisdiction or the institution 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 the suspension of any such
qualification 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 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 supplement the Final Prospectus to comply with the Act or the Exchange Act or
the respective rules thereunder, the Company promptly will (1) notify the
Representatives of such event, (2) prepare and file with the Commission, subject
to the second sentence of paragraph (a) of this Section 5, an amendment or
supplement which will correct such statement or omission or effect such
compliance and (3) supply any supplemented Final Prospectus to you in such
quantities as you may reasonably request.

        (c) As soon as practicable, the Company will make generally available to
its security holders and to the Representatives an earnings statement or
statements 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 the Representatives and counsel for the
Underwriters, without charge, signed copies of the Registration Statement
(including exhibits thereto) and to each other Underwriter a copy of the
Registration Statement (without exhibits thereto) 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
supplement thereto as the Representatives may reasonably request. The Company
will pay the expenses of printing or other




                                       7
<PAGE>   8

production of all documents relating to the offering.

        (e) The Company will arrange, if necessary, 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 and will pay any fee of the National
Association of Securities Dealers, Inc., in connection with its review of the
offering; provided that in no event shall the Company be obligated to qualify to
do business in any jurisdiction where it is not now so qualified or to take any
action that would subject it to service of process in suits, other than those
arising out of the offering or sale of the Securities, in any jurisdiction where
it is not now so subject.

        (f) The Company will not, without the prior written consent of [-]
offer, sell, contract to sell, pledge, or otherwise dispose of, (or enter into
any transaction which is designed to, or might reasonably be expected to, result
in the disposition (whether by actual disposition or effective economic
disposition due to cash settlement or otherwise) by the Company or any affiliate
of the Company or any person in privity with the Company or any affiliate of the
Company) directly or indirectly, including the filing (or participation in the
filing) of a registration statement with the Commission in respect of, or
establish or increase a put equivalent position or liquidate or decrease a call
equivalent position within the meaning of Section 16 of the Exchange Act, any
debt securities (other than the Securities) issued or guaranteed by the Company
which mature more than one year after the Closing Date and which are
substantially similar to the Securities, or publicly announce an intention to
effect any such transaction, until the Business Day set forth on Schedule I
hereto.

        (g) The Company will not take, directly or indirectly, any action
designed to or which has constituted or which might reasonably be expected to
cause or result, under the Exchange Act or otherwise, in stabilization or
manipulation of the price of any security of the Company to facilitate the sale
or resale of the Securities.

        6. Conditions to the Obligations of the Underwriters. The obligations of
the Underwriters to purchase the Securities shall be subject to the accuracy of
the representations and warranties on the part of the Company contained herein
as of the Execution Time and the Closing Date, to the accuracy of the statements
of the Company made in any certificates pursuant to the provisions hereof, to
the performance by the Company of its obligations hereunder and to the following
additional conditions:

        (a) If the Registration Statement has not become effective prior to the
Execution Time, unless the Representatives agree in writing to a later time, the
Registration Statement will become effective not later than (i) 6:00 PM New York
City time, on the date of determination of the public offering price, if such
determination occurred at or prior to 3:00 PM New York City time on such date or
(ii) 9:30 AM on the Business Day following the day on which the public offering
price was determined, if such determination occurred after 3:00 PM New York City
time on such date; if filing of the Final Prospectus, or any supplement thereto,
is required pursuant to Rule 424(b), the Final




                                       8
<PAGE>   9

Prospectus, and any such supplement, will be filed in the manner and within the
time period required by Rule 424(b); and no stop order suspending the
effectiveness of the Registration Statement shall have been issued and no
proceedings for that purpose shall have been instituted or threatened.

        (b) The Company's general counsel shall have furnished to the
Representatives such counsel's opinion to the effect of subparagraphs (i), (ii),
(iii), (iv), (v), (vii), (xii) and (xiv) below, and shall have requested and
caused Perkins Coie LLP, counsel for the Company, to have furnished to the
Representatives their opinion to the effect of subparagraphs (vi), (vii) (in so
far as (vii) relates to the compliance as to form of the documents incorporated
by reference in the Final Prospectus as amended or supplemented), (viii), (ix),
(x), (xi) and (xiii) below, in each case dated the Closing Date and addressed to
the Representatives:

                (i) the Company has been duly incorporated and is validly
        existing as a corporation in good standing under the laws of the State
        of Washington, with power and authority (corporate and other) to own its

        Prospectus, and has been duly qualified as a foreign corporation for the
        transaction of business and is in good standing (or the local
        equivalent) under the laws of each other jurisdiction in which it owns
        or leases properties or conducts any business so as to require such
        qualification, or is subject to no material liability or disability by
        reason of the failure to be so qualified in any such jurisdiction;

                (ii) each Significant Subsidiary of the Company has been duly
        organized and is validly existing as a corporation in good standing
        under the laws of the jurisdiction of its incorporation, with power and
        authority (corporate and other) to own its properties and conduct its
        business as described in the Final Prospectus, and has been duly
        qualified as a foreign corporation for the transaction of business and
        is in good standing (or the local equivalent) under the laws of each
        other jurisdiction in which it owns or leases properties or conducts
        any business so as to require such qualification, or is subject to no
        material liability or disability by reason of the failure to be so
        qualified in any such jurisdiction;

                (iii) all the outstanding shares of capital stock of each
        Significant Subsidiary have been duly and validly authorized and issued
        and are fully paid and nonassessable, and, except as otherwise set forth

        Significant Subsidiaries are owned by the Company either directly or
        through wholly owned subsidiaries free and clear of any perfected
        security interest and, to the knowledge of such counsel, after due
        inquiry, any other security interest, claim, lien or encumbrance;

                (iv) the Company's authorized equity capitalization is as set
        forth in the Final Prospectus;

                (v) to the knowledge of such counsel, there is no pending or
        threatened action, suit or proceeding by or before any court or
        governmental agency, authority or body or any arbitrator involving the
        Company or any of its subsidiaries or its or their property, of a



                                       9
<PAGE>   10

        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 Statement or Final Prospectus, or to be
        filed as an exhibit thereto, which is not described or filed as
        required;

               (vi) the Registration Statement has become effective under the
        Act; any required filing of the Basic Prospectus, any Preliminary Final
        Prospectus and the Final Prospectus, and any supplements thereto,
        pursuant to Rule 424(b) has been made in the manner and within the time
        period required by Rule 424(b); to the 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, and the Registration Statement and the Final Prospectus
        (other than the financial statements and other financial and statistical
        information contained therein, as to which such counsel need express no
        opinion) comply as to form in all material respects with the applicable
        requirements of the Act, the Exchange Act and the Trust Indenture Act
        and the respective rules thereunder; and such counsel has no reason to
        believe that on the Effective Date or at the Execution Time the
        Registration Statement 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 of its date and on the Closing Date included or
        includes any untrue statement of a material fact or omitted 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
        (in each case, other than the financial statements and other financial
        and statistical information contained therein, as to which such counsel
        need express no opinion);

                (vii) the documents incorporated by reference in the Final
        Prospectus as amended or supplemented (other than the financial
        statements and related schedules and other financial and statistical
        information therein, as to which such counsel need express no opinion),
        when they became effective or were filed with the Commission, as the
        case may be, complied as to form in all material respects with the
        requirements of the Act or the Exchange Act, as applicable, and the
        rules and regulations of the Commission thereunder; and they have no
        reason to believe that any of such documents, when they became effective
        or were so filed, as the case may be, contained, in the case of a
        registration statement which became effective under the Act, an untrue
        statement of a material fact or omitted to state a material fact
        required to be stated therein or necessary to make the statements
        therein not misleading, or, in the case of other documents which were
        filed under the Act or the Exchange Act with the Commission, an untrue
        statement of a material fact or omitted to state a material fact
        necessary in order to make the statements therein, in the light of the
        circumstances under which they were made when such documents were so
        filed, not misleading;

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

                (ix) the Indenture has been duly authorized, executed and
        delivered by the




                                       10
<PAGE>   11

        Company and (assuming the due authorization, execution and delivery
        thereof by the Trustee) is a valid and legally binding obligation of the
        Company enforceable in accordance with its terms, except as enforcement
        thereof may be limited by bankruptcy, insolvency, reorganization,
        moratorium or other laws relating to or affecting enforcement of
        creditors' rights generally or by general equity principles; and the
        Indenture has been duly qualified under the Trust Indenture Act;

                (x) the Securities have been duly authorized for issuance, offer
        and sale pursuant to this Agreement and, when issued, authenticated and
        delivered pursuant to the provisions of this Agreement and the Indenture
        against payment of the consideration therefor specified in the Final
        Prospectus, the Securities will constitute valid and legally binding
        obligations of the Company enforceable in accordance with their terms,
        except as enforcement thereof may be limited by bankruptcy, insolvency,
        reorganization, moratorium or other laws relating to or affecting
        enforcement of creditors' rights generally or by general equity
        principles; and the Securities and the Indenture conform to the
        descriptions thereof in the Final Prospectus;

                (xi) no consent, approval, authorization, filing with or order
        of any court or governmental agency or body is required in connection
        with the transactions contemplated herein, 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 purchase and
        distribution of the Securities by the Underwriters in the manner
        contemplated in this Agreement and in the Final Prospectus and such
        other approvals (specified in such opinion) as have been obtained;

                (xii) neither the execution and delivery of the Indenture, the
        issue and sale of the Securities, nor the consummation of any other of
        the transactions herein contemplated nor the fulfillment of the terms
        hereof will conflict with, result in a breach or violation of or
        imposition of any lien, charge or encumbrance upon any property or
        assets of the Company or any of its Significant Subsidiaries pursuant
        to, (i) the charter or by-laws of the Company or its Significant
        Subsidiaries, (ii) the terms of any indenture, contract, lease,
        mortgage, deed of trust, note agreement, loan agreement or other
        agreement, obligation, condition, covenant or instrument to which the
        Company or any of its Significant Subsidiaries is a party or bound or to
        which its or their property is subject, or (iii) any statute, law, rule,
        regulation, judgment, order or decree applicable to the Company or its
        Significant Subsidiaries of any court, regulatory body, administrative
        agency, governmental body, arbitrator or other authority having
        jurisdiction over the Company or its Significant Subsidiaries or any of
        its or their properties;

               (xiii) the Company is not and, after giving effect to the
        offering and sale of the Securities and the application of the proceeds
        thereof as described in the Final Prospectus, will not be an "investment
        company" as defined in the Investment Company Act of 1940, as amended;
        and

               (xiv) no holders of securities of the Company have rights to the
        registration of such



                                       11
<PAGE>   12

        securities under the Registration Statement.

In rendering such opinions, each such counsel may (A) limit such opinions to
the laws of the State of Washington and the Federal laws of the United States
and, in the case of the opinion to be delivered by Perkins Coie LLP with
respect to paragraph (ix) above, Perkins Coie LLP may assume that the laws of
the State of New York are the same as the laws of the State of Washington, and
(B) rely as to matters of fact, to the extent they deem proper, on certificates
of responsible officers of the Company and public officials. References to the
Final Prospectus in this paragraph (b) include any supplements thereto at the
Closing Date.

        (c) The Representatives shall have received from Mayer, Brown & Platt,
counsel for the Underwriters, such opinion or opinions, dated the Closing Date
and addressed to the Representatives, with respect to the issuance and sale of
the Securities, the Indenture, the Registration Statement, the Final Prospectus
(together with any supplement thereto) 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 or the President
and the principal financial or accounting officer of the Company, dated the
Closing Date, to the effect that the signers of such certificate have examined
the Registration Statement, the Final Prospectus, any supplements to the Final
Prospectus 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 or incorporated by reference in the Final Prospectus (exclusive
        of any supplement thereto), there has been no material adverse effect on
        the condition (financial or otherwise), prospects, earnings, business or
        properties of the Company and its subsidiaries, taken as a whole,
        whether or not arising from transactions in the ordinary course of
        business, except as set forth in or contemplated in the Final Prospectus
        (exclusive of any supplement thereto)

        (e) At the date hereof and at the Closing Date, Ernst & Young LLP shall
have furnished to the Representatives letters, dated respectively as of the date
hereof and as of the Closing Date, in




                                       12
<PAGE>   13

form and substance satisfactory to the Representatives, confirming that they are
independent accountants within the meaning of the Act and the Exchange Act and
the respective applicable published rules and regulations thereunder and
stating, as of such date hereof or the Closing Date, as the case may be, (or
with respect to matters involving changes or developments since the respective
dates as of which specified financial information is given in the Final
Prospectus, as of a date not more than five days prior to either such date), the
conclusions and findings of such firm with respect to the financial information
and other matters as provided in SAS No. 72.

        (f) Subsequent to the Execution Time or, if earlier, the dates as of
which information is given in the Registration Statement (exclusive of any
amendment thereof) and the Final Prospectus (exclusive of any supplement
thereto), there shall not have been (i) any change or decrease specified in the
letter or letters referred to in paragraph (e) of this Section 6 or (ii) any
change, or any development involving a prospective change, in or affecting the
condition (financial or otherwise), earnings, business or properties of the
Company and its subsidiaries, taken as a whole, whether or not arising from
transactions in the ordinary course of business, except as set forth in or
contemplated in the Final Prospectus (exclusive of any supplement thereto) the
effect of which, in any case referred to in clause (i) or (ii) above, is, in the
sole judgment of the Representatives, so material and adverse as to make it
impractical or inadvisable to proceed with the offering or delivery of the
Securities as contemplated by the Registration Statement (exclusive of any
amendment thereof) and the Final Prospectus (exclusive of any supplement
thereto).

        (g) Subsequent to the Execution Time, there shall not have been any
decrease in the rating of any of the Company's debt securities by any
"nationally recognized statistical rating organization" (as defined for purposes
of Rule 436(g) under the Act) or any notice given of any intended or potential
decrease in any such rating or of a possible change in any such rating that does
not indicate the direction of the possible change.

        (h) 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.

        If any of the conditions specified in this Section 6 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 counsel for the Underwriters, this
Agreement and all obligations of the Underwriters hereunder may be canceled at,
or at 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
facsimile confirmed in writing.

        The documents required to be delivered by this Section 6 shall be
delivered at the office of Mayer, Brown & Platt, counsel for the Underwriters,
at 1675 Broadway, New York, New York 10019, on the Closing Date.

        7. Reimbursement of Underwriters' Expenses. If the sale of the
Securities provided for



                                       13
<PAGE>   14

herein is not consummated because any condition to the obligations of the
Underwriters set forth in Section 6 hereof is not satisfied, because of any
termination pursuant to Section 10 hereof 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, the Company will reimburse the Underwriters severally through
[-] on demand for all out-of-pocket expenses (including
reasonable fees and disbursements of counsel) that shall have been incurred by
them in connection with the proposed purchase and sale of the Securities.

        8. Indemnification and Contribution. (a) The Company agrees to indemnify
and hold harmless each Underwriter, the directors, officers, employees and
agents of each Underwriter and each person who controls any Underwriter 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 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 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, as incurred, 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 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 inclusion therein; provided, further, that with respect to any
untrue statement or omission of material fact made in any Preliminary
Prospectus, the indemnity agreement contained in this Section 8(a) shall not
inure to the benefit of any Underwriter from whom the person asserting any such
loss, claim, damage or liability purchased the Securities concerned, to the
extent that any such loss, claim, damage or liability of such Underwriter occurs
under the circumstance where (x) the Company had previously furnished copies of
the Final  Prospectus to the Representatives, (y) the untrue statement or
omission of a material fact contained in the Preliminary Prospectus was
corrected in the Final Prospectus and (z) such Underwriter did not send or give
to such person, at or prior to the written sale of such Securities to such
person, a copy of the Final Prospectus. This indemnity agreement will be in
addition to any liability which the Company may otherwise have.

        (b) Each Underwriter severally and not jointly 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 each Underwriter, but only with




                                       14
<PAGE>   15

reference to written information relating to such Underwriter furnished to the
Company by or on behalf of such Underwriter through the Representatives
specifically for inclusion in the documents referred to in the foregoing
indemnity. This indemnity agreement will be in addition to any liability which
any Underwriter may otherwise have. The Company acknowledges that the statements
set forth in the last paragraph of the cover page regarding delivery of the
Securities, the legend in block capital letters on page ______ related to
stabilization, syndicate covering transactions and penalty bids and, under the
heading "Underwriting" or "Plan of Distribution," (i) the list of Underwriters
and their respective participation in the sale of the Securities, (ii) the
sentences related to concessions and reallowances and (iii) the paragraph
related to stabilization, syndicate covering transactions and penalty bids in
any Preliminary Final Prospectus and the Final Prospectus constitute the only
information furnished in writing by or on behalf of the several Underwriters for
inclusion in any Preliminary Final Prospectus or the Final Prospectus.

        (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 failure so to notify the indemnifying party (i) will not relieve it from
liability under paragraph (a) or (b) above unless and to the extent it did not
otherwise learn of such action and such failure results in the forfeiture by the
indemnifying party of substantial rights and defenses and (ii) will not, in any
event, relieve the indemnifying party from any obligations to any indemnified
party other than the indemnification obligation provided in paragraph (a) or (b)
above. The indemnifying party shall be entitled to appoint counsel of the
indemnifying party's choice at the indemnifying party's expense to represent the
indemnified party in any action for which indemnification is sought (in which
case the indemnifying party shall not thereafter be responsible for the fees and
expenses of any separate counsel retained by the indemnified party or parties
except as set forth below); provided, however, that such counsel shall be
satisfactory to the indemnified party. Notwithstanding the indemnifying party's
election to appoint counsel to represent the indemnified party in an action, the
indemnified party shall have the right to employ separate counsel (including
local counsel), and the indemnifying party shall bear the reasonable fees, costs
and expenses of such separate counsel if (i) the use of counsel chosen by the
indemnifying party to represent the indemnified party would present such counsel
with a conflict of interest, (ii) the actual or potential defendants in, or
targets of, 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, (iii) 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 the institution of such action or (iv) the
indemnifying party shall authorize the indemnified party to employ separate
counsel at the expense of the indemnifying party. An indemnifying party will
not, without the prior written consent of the indemnified parties, settle or
compromise or consent to the entry of any judgment with respect to any pending
or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action)
unless such settlement, compromise or consent includes an unconditional release
of each indemnified party from




                                       15
<PAGE>   16

all liability arising out of such claim, action, suit or proceeding.

        (d) In the event that the indemnity provided in paragraph (a) or (b) of
this Section 8 is unavailable to or insufficient to hold harmless an indemnified
party for any reason, the Company and the Underwriters severally agree to
contribute to the aggregate losses, claims, damages and liabilities (including
legal or other expenses reasonably incurred in connection with investigating or
defending same) (collectively "Losses") to which the Company and one or more of
the Underwriters may be subject in such proportion as is appropriate to reflect
the relative benefits received by the Company on the one hand and by the
Underwriters on the other from the offering of the Securities; provided,
however, that in no case shall any Underwriter (except as may be provided in any
agreement among underwriters relating to the offering of the Securities) be
responsible for any amount in excess of the underwriting discount or commission
applicable to the Securities purchased by such Underwriter hereunder. If the
allocation provided by the immediately preceding sentence is unavailable for any
reason, the Company and the Underwriters severally shall contribute in such
proportion as is appropriate to reflect not only such relative benefits but also
the relative fault of the Company on the one hand and of the Underwriters on the
other in connection with the statements or omissions which resulted in such
Losses as well as any other relevant equitable considerations. Benefits received
by the Company shall be deemed to be equal to the total net proceeds from the
offering (before deducting expenses) received by it, and benefits received by
the Underwriters shall be deemed to be equal to the total underwriting discounts
and commissions, in each case as set forth on the cover page of the Final
Prospectus. Relative fault shall be determined by reference to, among other
things, whether any untrue or any alleged untrue statement of a material fact or
the omission or alleged omission to state a material fact relates to information
provided by the Company on the one hand or the Underwriters on the other, the
intent of the parties and their relative knowledge, access to information and
opportunity to correct or prevent such untrue statement or omission. The Company
and the Underwriters agree that it would not be just and equitable if
contribution were determined by pro rata allocation or any other method of
allocation which does not take account of the equitable considerations referred
to above. Notwithstanding the provisions of this paragraph (d), 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 an Underwriter within the meaning of either the Act or the Exchange Act
and each director, officer, employee and agent of an Underwriter shall have the
same rights to contribution as such Underwriter, 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 the applicable terms and conditions of this
paragraph (d).

        9. Default by an Underwriter. If any one or more Underwriters shall fail
to purchase and pay for any of the Securities 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 principal amount of
Securities set forth opposite




                                       16
<PAGE>   17

their names in Schedule II hereto bears to the aggregate principal amount of
Securities set forth opposite the names of all the remaining Underwriters) the
Securities which the defaulting Underwriter or Underwriters agreed but failed to
purchase; provided, however, that in the event that the aggregate principal
amount of Securities which the defaulting Underwriter or Underwriters agreed but
failed to purchase shall exceed 10% of the aggregate principal amount of
Securities 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 Securities, and if such nondefaulting Underwriters do not
purchase all the Securities, 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 9, the Closing Date shall be postponed
for such period, not exceeding five Business 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.

        10. 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 Securities, if at any time prior to such time
(i) trading in the Company's Common Stock shall have been suspended by the
Commission or the Nasdaq National Market or trading in securities generally on
the New York Stock Exchange or the Nasdaq National Market shall have been
suspended or limited or minimum prices shall have been established on such
Exchange or the Nasdaq National Market, (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 escalation of hostilities, declaration by
the United States of a national emergency or war, or other calamity or crisis
the effect of which on financial markets is such as to make it, in the sole
judgment of the Representatives, impractical or inadvisable to proceed with the
offering or delivery of the Securities as contemplated by the Final Prospectus
(exclusive of any supplement thereto).

        11. 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, employees, agents or controlling persons referred to in
Section 8 hereof, and will survive delivery of and payment for the Securities.
The provisions of Sections 7 and 8 hereof shall survive the termination or
cancellation of this Agreement.

        12. Notices. All communications hereunder will be in writing and
effective only on receipt, and, if sent to the Representatives, will be mailed,
delivered or telefaxed to [-] General Counsel (fax no.: (___) ___-____) and
confirmed to the General Counsel, [-, at -] New York, New York, 10013,

hereunder.

any provision of this Indenture, the Company shall furnish to the Trustee an
Officer's Certificate stating that all conditions precedent, if any, provided
for in this Indenture relating to the proposed action have been complied with

Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one

that such officer, after reasonable inquiry, has no reason to believe and does

<PAGE>   18

the matters upon which his certificate or opinion is based is erroneous. Any

certificate or opinion or representations with respect to such matters are
erroneous.

applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture or any Security, they may, but need not, be

        SECTION 1.4.  ACTS OF HOLDERS.

               (1) Any request, demand, authorization, direction, notice,
        consent, waiver or other action provided by or pursuant to this
        Indenture to be given or taken by Holders may be embodied in and
        evidenced by one or more instruments of substantially similar tenor
        signed by such Holders in person or by an agent duly appointed in
        writing. If, but only if, Securities of a series are issuable as Bearer
        Securities, any request, demand, authorization, direction, notice,
        consent, waiver or other action provided in or pursuant to this
        Indenture to be given or taken by Holders of Securities of such series
        may, alternatively, be embodied in and evidenced by the record of
        Holders of Securities of such series voting in favor thereof, either in
        person or by proxies duly appointed in writing, at any meeting of
        Holders of Securities of such series duly called and held in accordance
        with the provisions of Article 15, or a combination of such instruments
        and any such record. Except as herein otherwise expressly provided, such
        action shall become effective when such instrument or instruments or
        record or both are delivered to the Trustee and, where it is hereby
        expressly required, to the Company. Such instrument or instruments and
        any such record (and the action embodied therein and evidenced thereby)
        are herein sometimes referred to as the "Act" of the Holders signing
        such instrument or instruments or so voting at any such meeting. Proof
        of execution of any such instrument or of a writing appointing any such
        agent, or of the holding by any Person of a Security, shall be
        sufficient for any purpose of this Indenture and (subject to Section 315
        of the Trust Indenture Act) conclusive in favor of the Trustee and the
        Company and any agent of the Trustee and the Company, if made in the
        manner provided in this Section. The record of any meeting of Holders of
        Securities shall be proved in the manner provided in Section 15.6.

               Without limiting the generality of this Section 1.4, unless
        otherwise provided in or pursuant to this Indenture, a Holder, including
        a U.S. Depository that is a Holder of a global Security, may make, give
        or take, by a proxy or proxies, duly appointed in writing, any request,
        demand, authorization, direction, notice, consent, waiver or other Act
        provided in or pursuant to this Indenture to be made, given or taken by
        Holders, and a U.S. Depository that is a Holder of a global Security may
        provide its proxy or proxies to



                                       12
<PAGE>   19

        the beneficial owners of interests in any such global Security through
        such U.S. Depository's standing instructions and customary practices.

               The Company shall fix a record date for the purpose of
        determining the Persons who are beneficial owners of interest in any
        permanent global Security held by a U.S. Depository entitled under the
        procedures of such U.S. Depository to make, give or take, by a proxy or
        proxies duly appointed in writing, any request, demand, authorization,
        direction, notice, consent, waiver or other Act provided in or pursuant
        to this Indenture to be made, given or taken by Holders. If such a
        record date is fixed, the Holders on such record date or their duly
        appointed proxy or proxies, and only such Persons, shall be entitled to
        make, give or take such request, demand, authorization, direction,
        notice, consent, waiver or other Act, whether or not such Holders remain
        Holders after such record date. No such request, demand, authorization,
        direction, notice, consent, waiver or other Act shall be valid or
        effective if made, given or taken more than 90 days after such record
        date.

               (2) The fact and date of the execution by any Person of any such
        instrument or writing referred to in this Section 1.4 may be proved in
        any reasonable manner; and the Trustee may in any instance require
        further proof with respect to any of the matters referred to in this
        Section.

               (3) The ownership, principal amount and serial numbers of
        Registered Securities held by any Person, and the date of the
        commencement and the date of the termination of holding the same, shall
        be proved by the Security Register.

               (4) The ownership, principal amount and serial numbers of Bearer
        Securities held by any Person, and the date of the commencement and the
        date of the termination of holding the same, may be proved by the
        production of such Bearer Securities or by a certificate executed, as
        depositary, by any trust company, bank, banker or other depositary
        reasonably acceptable to the Company, wherever situated, if such
        certificate shall be deemed by the Company and the Trustee to be
        satisfactory, showing that at the date therein mentioned such Person had
        on deposit with such depositary, or exhibited to it, the Bearer
        Securities therein described; or such facts may be proved by the
        certificate or affidavit of the Person holding such Bearer Securities,
        if such certificate or affidavit is deemed by the Trustee to be
        satisfactory. The Trustee and the Company may assume that such ownership
        of any Bearer Security continues until (i) another certificate or
        affidavit bearing a later date issued in respect of the same Bearer
        Security is produced, or (ii) such Bearer Security is produced to the
        Trustee by some other Person, or (iii) such Bearer Security is
        surrendered in exchange for a Registered Security, or (iv) such Bearer
        Security is no longer Outstanding. The ownership, principal amount and
        serial numbers of Bearer Securities held by the Person so executing such
        instrument or writing and the date of the commencement and the date of
        the termination of holding the same may also be proved in any other
        manner which the Company and the Trustee deem sufficient.

               (5) If the Company shall solicit from the Holders of any
        Registered Securities any request, demand, authorization, direction,
        notice, consent, waiver or other Act, the Company may at its option (but
        is not obligated to), by Board Resolution, fix in advance a record date
        for the determination of Holders of Registered Securities entitled to
        give such request, demand, authorization, direction, notice, consent,
        waiver or other Act. If such a record date is fixed, such request,
        demand, authorization, direction, notice, consent, waiver or other Act
        may be given before or after such record date, but only the Holders of
        Registered Securities of record at the close of business on such record
        date shall be deemed to be Holders for the purpose of determining
        whether Holders of the requisite proportion of Outstanding Securities
        have authorized or agreed or consented to such request, demand,
        authorization, direction, notice, consent, waiver or other Act, and for
        that purpose the Outstanding Securities shall be computed as of such
        record date; provided that no such authorization, agreement or consent
        by the Holders of Registered Securities shall be deemed effective unless
        it shall become effective pursuant to the provisions of this Indenture
        not later than six months after the record date.

               (6) Any request, demand, authorization, direction, notice,
        consent, waiver or other Act by 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 or suffered to
        be done by the Trustee, any Security Registrar, any Paying Agent or the
        Company in reliance thereon, whether or not notation of such Act is made
        upon such Security.

        SECTION 1.5.  NOTICES, ETC. TO THE TRUSTEE AND THE COMPANY.

        Any request, demand, authorization, direction, notice, consent, waiver
or other Act of Holders or other document provided or permitted by this
Indenture to be made upon, given or furnished to, or filed with,

               (1) the Trustee by any Holder or the Company shall be sufficient
        for every purpose hereunder if made, given, furnished or filed in
        writing to or with the Trustee at its Corporate Trust Office, or

               (2) the Company by the Trustee or any Holder shall be sufficient
        for every purpose hereunder (unless otherwise herein expressly provided)
        if in writing and mailed, first-class postage prepaid, to the Company
        addressed to the attention of its Chief Financial Officer, Controller or
        Secretary, at the address of its principal office specified in the first
        paragraph of this instrument or at any other address previously
        furnished in writing to the Trustee by the Company.

        SECTION 1.6.  NOTICE TO HOLDERS OF SECURITIES; WAIVER.

        Except as otherwise expressly provided in or pursuant to this Indenture,
where this Indenture provides for notice to Holders of Securities of any event,



                                       14
<PAGE>   21

               (1) such notice shall be sufficiently given to Holders of
        Registered Securities if in writing and mailed, first-class postage
        prepaid, to each Holder of a Registered Security affected 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; and

               (2) such notice shall be sufficiently given to Holders of Bearer
        Securities, if any, if published in an Authorized Newspaper in The City
        of New York and, if such Securities are then listed on any stock
        exchange outside the United States, in an Authorized Newspaper in such
        city as the Company shall advise the Trustee that such stock exchange so
        requires, on a Business Day at least twice, the first such publication
        to be not earlier than the earliest date and the second such publication
        not later than the latest date prescribed for the giving of such notice.

        In any case where notice to Holders of Registered Securities is given by
mail, neither the failure to mail such notice, nor any defect in any notice so
mailed, to any particular Holder of a Registered Security shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities or the sufficiency of any notice to Holders of Bearer Securities
given as provided herein. Any notice which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given or provided. In
the case by reason of the suspension of regular mail service or by reason of any
other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall constitute
a sufficient notification for every purpose hereunder.

        In case by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearers Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder. Neither failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published, shall affect the sufficiency of any notice mailed to
Holders of Registered Securities as provided above.

        Where this Indenture provides for notice in any manner, such notice may
be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Holders of Securities shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

        SECTION 1.7.  LANGUAGE OF NOTICES.

        Any request, demand, authorization, direction, notice, consent, election
or waiver required or permitted under this Indenture shall be in the English
language, except that, if the Company so elects, any published notice may be in
an official language of the country of publication.

        If any provision hereof limits, qualifies or conflicts with any duties
under any required provision of the Trust Indenture Act imposed hereon by
Section 318(c) thereof, such required provision shall control.

        SECTION 1.9.  EFFECT OF HEADINGS AND TABLE OF CONTENTS.

        The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

        SECTION 1.10.  SUCCESSORS AND ASSIGNS.

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

        SECTION 1.11.  SEPARABILITY CLAUSE.

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

        SECTION 1.12.  BENEFITS OF INDENTURE.

        Nothing in this Indenture, any Security or any Coupon, express or
implied, shall give to any Person, other than the parties hereto, any Security
Registrar, any Paying Agent, any Authenticating Agent and their successors
hereunder and the Holders of Securities or Coupons, any benefit or any legal or
equitable right, remedy or claim under this Indenture.

        SECTION 1.13.  GOVERNING LAW.

        This Indenture, the Securities and any Coupons shall be governed by and
construed in accordance with the laws of the State of New York applicable to
agreements made or instruments entered into and, in each case, performed in said
state.

        SECTION 1.14.  LEGAL HOLIDAYS.

        Unless otherwise specified in or pursuant to this Indenture or any
Securities, in any case where any Interest Payment Date, Stated Maturity or
Maturity of any Security, or the last date on which a Holder has the right to
convert or exchange Securities of a series that are convertible or exchangeable,
shall be a Legal Holiday at any Place of Payment, then (notwithstanding any
other provision of this Indenture, any Security or any Coupon other than a
provision in any Security or Coupon that specifically states that such provision
shall apply in lieu hereof) payment need not be made at such Place of Payment on
such date, and such Securities need not be converted or exchanged on such date
but such payment may be made, and such Securities may be converted or exchanged,
on the next succeeding day that is a Business Day at such Place of Payment with



                                       16
<PAGE>   23

the same force and effect as if made on the Interest Payment Date or at the
Stated Maturity or Maturity or on such last day for conversion or exchange, and
no interest shall accrue on the amount payable on such date or at such time for
the period from and after such Interest Payment Date, Stated Maturity, Maturity
or last day for conversion or exchange, as the case may be, to such next
succeeding Business Day.

        SECTION 1.15.  COUNTERPARTS.

        This Indenture may be executed in several counterparts, each of which
shall be an original and all of which shall constitute but one and the same
instrument.

        SECTION 1.16.  JUDGMENT CURRENCY.

        The Company agrees, to the fullest extent that it may effectively do so
under applicable law, that (a) if for the purpose of obtaining judgment in any
court it is necessary to convert the sum due in respect of the principal of, or
premium or interest, if any, or Additional Amounts on the Securities of any
series (the "Required Currency") into a currency in which a judgment will be
rendered (the "Judgment Currency"), the rate of exchange used shall be the rate
at which in accordance with normal banking procedures the Trustee could purchase
in The City of New York the requisite amount of the Required Currency with the

represent the aggregate amount of all Outstanding Securities of such series (or
such lesser amount as is permitted by the terms thereof) from time to time
endorsed thereon and may also provide that the aggregate amount of Outstanding
Securities represented thereby may from time to time be increased or reduced to

amount, or any increase or decrease in the amount, or changes in the rights of
Holders, of Outstanding Securities represented thereby shall be made in such
manner and by such Person or Persons as shall be specified therein or in the
Company Order to be delivered pursuant to Section 3.3 or 3.4 with respect

3.4, the Trustee shall deliver and redeliver, in each case at the Company's
expense, any Security in permanent global form in the manner and upon
instructions given by the Person or Persons specified therein or in the
applicable Company Order. If a Company Order pursuant to Section 3.3 or 3.4 has
been, or simultaneously is, delivered, any instructions by the Company with
respect to a Security in global form shall be in writing but need not be
accompanied by or contained in an Officer's Certificate and need not be
accompanied by an Opinion of Counsel.

        Notwithstanding the provisions of Section 3.7, unless otherwise
specified in or pursuant to this Indenture or any Security, payment of principal
of, any premium and interest on, and any Additional Amounts in respect of, any
Security in temporary or permanent global form shall be made to the Person or
Persons specified therein.

        Notwithstanding the provisions of Section 3.8 and except as provided in
the preceding paragraph, the Company, the Trustee and any agent of the Company
or the Trustee shall treat as the Holder of such principal amount of Outstanding
Securities represented by a global Security (i) in the case of a global Security
in registered form, the Holder of such global Security in registered form, or
(ii) in the case of a global Security in bearer form, the Person or Persons
specified pursuant to Section 3.1.

in relation to such Securities and any Coupons appertaining thereto, the Trustee
shall be entitled to receive, and (subject to Sections 315(a) through 315(d) of
the Trust Indenture Act) shall be fully protected in relying upon,

               (1)    an Opinion of Counsel to the effect that:

                      (a) the form or forms and terms of such Securities and
               Coupons, if any, have been established in conformity with the

               insertions, executed under the Company's corporate seal and
               attested by duly authorized officers of the Company, delivered by
               duly authorized officers of the Company to the Trustee for

               and subject to any conditions specified in such Opinion of
               Counsel, will constitute legally valid and binding obligations of
               the Company, enforceable against the Company in accordance with
               their terms, except as enforcement thereof may be subject to or
               limited by bankruptcy, insolvency, reorganization, moratorium,
               arrangement, fraudulent conveyance, fraudulent transfer or other
               similar laws relating to or affecting creditors' rights
               generally, and subject to general principles of equity
               (regardless of whether enforcement is sought in a proceeding in
               equity or at law) and will entitle the Holders thereof to the
               benefits of this Indenture; such Opinion of Counsel need express
               no opinion as to the availability of equitable remedies;

                      (c) all laws and requirements in respect of the execution
               and delivery by the Company of such Securities and Coupons, if
               any, have been complied with; and

                      (d) this Indenture has been qualified under the Trust
               Indenture Act; and

        of the Persons executing such certificate, all conditions precedent to
        the execution, authentication and delivery of such Securities and
        Coupons, if any, appertaining thereto, have been complied with, and no
        event which is, or after notice or lapse of time would become, an Event
        of Default with respect to any of the Securities shall have occurred and
        be continuing.

        If all the Securities of any series are not to be issued at one time, it
shall not be necessary to deliver an Opinion of Counsel and an Officer's
Certificate at the time of issuance of each Security, but such opinion and
certificate, with appropriate modifications, shall be delivered at or before the
time of issuance of the first Security of such series. After any such first
delivery, any separate written request by an Authorized Officer of the Company
or any person designated in writing by an Authorized Officer that the Trustee
authenticate and deliver Securities of such series for original issue will be
deemed to be a certification by the Company that all conditions precedent
provided for in this Indenture relating to authentication and delivery of such
Securities continue to have been complied with and that no Event of Default with
respect to any of the Securities has occurred or is continuing.

        The Trustee shall not be required to authenticate or to cause an
Authenticating Agent to authenticate any 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 or if the Trustee,
being advised by counsel, determines that such action may not lawfully be taken.



                                       25
<PAGE>   32

        Each Registered Security shall be dated the date of its authentication.
Each Bearer Security and any Bearer Security in global form shall be dated as of
the date specified in or pursuant to this Indenture.

        No Security or Coupon appertaining thereto 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 in Section 2.2 or 6.11 executed by or on behalf of the
Trustee or by the Authenticating Agent by the manual signature of one of its
authorized officers. Such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated
and delivered hereunder. Except as permitted by Section 3.6 or 3.7, the Trustee
shall not authenticate and deliver any Bearer Security unless all Coupons
appertaining thereto then matured have been detached and cancelled.

        SECTION 3.4.  TEMPORARY SECURITIES.

        Pending the preparation of definitive Securities, the Company may
execute and deliver to the Trustee and, upon Company Order, the Trustee shall
authenticate and deliver, in the manner provided in Section 3.3, temporary
Securities in lieu thereof 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, in registered form or, if authorized in or pursuant to this
Indenture, in bearer form with one or more Coupons or without Coupons and with
such appropriate insertions, omissions, substitutions and other variations as
the officers of the Company executing such Securities may determine, as
conclusively evidenced by their execution of such Securities. Such temporary
Securities may be in global form.

        Except in the case of temporary Securities in global form, which shall
be exchanged in accordance with the provisions thereof, if temporary Securities
are issued, the Company shall cause definitive Securities to be prepared without
unreasonable delay. After the preparation of definitive Securities of the same
series and containing terms and provisions that are identical to those of any
temporary Securities, such temporary Securities shall be exchangeable for such
definitive Securities upon surrender of such temporary Securities at an Office
or Agency for such Securities, without charge to any Holder thereof. Upon
surrender for cancellation of any one or more temporary Securities (accompanied
by any unmatured Coupons appertaining thereto), the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of authorized denominations of the same series
and containing identical terms and provisions; provided, however, that no
definitive Bearer Security, except as provided in or pursuant to this Indenture,
shall be delivered in exchange for a temporary Registered Security; and
provided, further, that a definitive Bearer Security shall be delivered in
exchange for a temporary Bearer Security only in compliance with the conditions
set forth in or pursuant to this Indenture. Unless otherwise provided in or
pursuant to this Indenture with respect to a temporary global Security, 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 3.5.  REGISTRATION, TRANSFER AND EXCHANGE.

        With respect to the Registered Securities of each series, if any, the
Company shall cause to be kept a register (each such register being herein
sometimes referred to as the "Security Register") at an Office or Agency for
such series in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of the Registered
Securities of such series and of transfers of the Registered Securities of such
series. Such Office or Agency shall be the "Security Registrar" for that series
of Securities. Unless otherwise specified in or pursuant to this Indenture or
the Securities, the Trustee shall be the initial Security Registrar for each
series of Securities. The Company shall have the right to remove and replace
from time to time the Security Registrar for any series of Securities; provided
that no such removal or replacement shall be effective until a successor
Security Registrar with respect to such series of Securities shall have been
appointed by the Company and shall have accepted such appointment by the
Company. In the event that the Trustee shall not be or shall cease to be
Security Registrar with respect to a series of Securities, it shall have the
right to examine the Security Register for such series at all reasonable times.
There shall be only one Security Register for each series of Securities.

        Upon surrender for registration of transfer of any Registered Security
of any series at any Office or Agency for such series, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Registered Securities of
the same series denominated as authorized in or pursuant to this Indenture, of a
like aggregate principal amount bearing a number not contemporaneously
outstanding and containing identical terms and provisions.

        At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series containing
identical terms and provisions, in any authorized denominations, and of a like
aggregate principal amount, upon surrender of the Securities to be exchanged at
any Office or Agency for such series. Whenever any Registered Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Registered Securities which the Holder making the
exchange is entitled to receive.

        If provided in or pursuant to this Indenture, with respect to Securities
of any series, at the option of the Holder, Bearer Securities of such series may
be exchanged for Registered Securities of such series containing identical
terms, denominated as authorized in or pursuant to this Indenture and in the
same aggregate principal amount, upon surrender of the Bearer Securities to be
exchanged at any Office or Agency for such series, with all unmatured Coupons
and all matured Coupons in default thereto appertaining. If the Holder of a
Bearer Security is unable to produce any such unmatured Coupon or Coupons or
matured Coupon or Coupons in default, such exchange may be effected if the
Bearer Securities are accompanied by payment in funds acceptable to the Company
and the Trustee in an amount equal to the face amount of such missing Coupon or
Coupons, or the surrender of such missing Coupon or Coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity



                                       27
<PAGE>   34

as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Bearer Security shall surrender to any Paying
Agent any such missing Coupon in respect of which such a payment shall have been
made, such Holder shall be entitled to receive the amount of such payment;
provided, however, that, except as otherwise provided in Section 10.2, interest
represented by Coupons shall be payable only upon presentation and surrender of
those Coupons at an Office or Agency for such series located outside the United
States. Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such Office or Agency for such series in exchange for a
Registered Security of such series and like tenor after the close of business at
such Office or Agency on (i) any Regular Record Date and before the opening of
business at such Office or Agency on the next succeeding Interest Payment Date,
or (ii) any Special Record Date and before the opening of business at such
Office or Agency on the related date for payment of Defaulted Interest, such
Bearer Security shall be surrendered without the Coupon relating to such
Interest Payment Date or proposed date of payment, as the case may be (or, if
such Coupon is so surrendered with such Bearer Security, such Coupon shall be
returned to the Person so surrendering the Bearer Security), and interest or
Defaulted Interest, as the case may be, shall not be payable on such Interest
Payment Date or proposed date for payment, as the case may be, in respect of the
Registered Security issued in exchange for such Bearer Security, but shall be
payable only to the Holder of such Coupon when due in accordance with the
provisions of this Indenture.

        If provided in or pursuant to this Indenture with respect to Securities
of any series, at the option of the Holder, Registered Securities of such series
may be exchanged for Bearer Securities upon such terms and conditions as may be
provided in or pursuant to this Indenture with respect to such series.

        Whenever any Securities are surrendered for exchange as contemplated by
the immediately preceding two paragraphs, the Company shall execute, and the
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive.

        Notwithstanding the foregoing, except as otherwise provided in or
pursuant to this Indenture, any global Security shall be exchangeable for
definitive Securities only if (i) the Depository is at any time unwilling,
unable or ineligible to continue as depository and a successor depository is not
appointed by the Company within 90 days of the date the Company is so informed
in writing, (ii) the Company executes and delivers to the Trustee a Company
Order to the effect that such global Security shall be so exchangeable, or (iii)
an Event of Default has occurred and is continuing with respect to the
Securities. If the beneficial owners of interests in a global Security are
entitled to exchange such interests for definitive Securities as the result of
an event described in clause (i), (ii) or (iii) of the preceding sentence, then
without unnecessary delay but in any event not later than the earliest date on
which such interests may be so exchanged, the Company shall deliver to the
Trustee definitive Securities in such form and denominations as are required by
or pursuant to this Indenture, and of the same series, containing identical
terms and in aggregate principal amount equal to the principal amount of such
global Security, executed by the Company. On or after the earliest date on which
such interests may be



                                       28
<PAGE>   35

so exchanged, such global Security shall be surrendered from time to time by the
U.S. Depository or such other Depository as shall be specified in the Company
Order with respect thereto, and in accordance with instructions given to the
Trustee and the U.S. Depository or such other Depository, as the case may be
(which instructions shall be in writing but need not be contained in or
accompanied by an Officer's Certificate or be accompanied by an Opinion of
Counsel), as shall be specified in the Company Order with respect thereto to the
Trustee, as the Company's agent for such purpose, to be exchanged, in whole or
in part, for definitive Securities as described above without charge. The
Trustee shall authenticate and make available for delivery, in exchange for each
portion of such surrendered global Security, a like aggregate principal amount
of definitive Securities of the same series of authorized denominations and of
like tenor as the portion of such global Security to be exchanged, which (unless
such Securities are not issuable both as Bearer Securities and as Registered
Securities, in which case the definitive Securities exchanged for the global
Security shall be issuable only in the form in which the Securities are
issuable, as provided in or pursuant to this Indenture) shall be in the form of
Bearer Securities or Registered Securities, or any combination thereof, as shall
be specified by the beneficial owner thereof, but subject to the satisfaction of
any certification or other requirements to the issuance of Bearer Securities;
provided, however, that no such exchanges may occur during a period beginning at
the opening of business 15 days before any selection of Securities of the same
series to be redeemed and ending on the relevant Redemption Date; and provided,
further, that (unless otherwise provided in or pursuant to this Indenture) no
Bearer Security delivered in exchange for a portion of a global Security shall
be mailed or otherwise delivered to any location in the United States. Promptly
following any such exchange in part, such global Security shall be returned by
the Trustee to such Depository or the U.S. Depository, as the case may be, or
such other Depository or U.S. Depository referred to above in accordance with
the instructions of the Company referred to above. If a Registered Security is
issued in exchange for any portion of a global Security after the close of
business at the Office or Agency for such Security where such exchange occurs on
or after (i) any Regular Record Date for such Security and before the opening of
business at such Office or Agency on the next succeeding Interest Payment Date,
or (ii) any Special Record Date for such Security and before the opening of
business at such Office or Agency on the related proposed date for payment of
interest or Defaulted Interest, as the case may be, interest shall not be
payable on such Interest Payment Date or proposed date for payment, as the case
may be, in respect of such Registered Security, but shall be payable on such
Interest Payment Date or proposed date for payment, as the case may be, only to
the Person to whom interest in respect of such portion of such global Security
shall be payable in accordance with the provisions of this Indenture.

        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 entitling the Holders thereof to the same benefits under this Indenture
as the Securities surrendered upon such registration of transfer or exchange.

        Every Registered Security presented or surrendered for registration of
transfer or for exchange or redemption shall (if so required by the Company or
the Security Registrar for such Security) be duly endorsed, or be accompanied by
a written instrument of transfer in form



                                       29
<PAGE>   36

satisfactory to the Company and the Security Registrar for such Security 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, or redemption of Securities, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge and any other
expenses (including fees and expenses of the Trustee) that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 3.4, 9.5 or 11.7 not involving any transfer.

        Except as otherwise provided in or pursuant to this Indenture, the
Company shall not be required (i) to issue, register the transfer of or exchange
any Securities during a period beginning at the opening of business 15 days
before the day of mailing of a notice of redemption of Securities of like tenor
and the same series under Section 11.3 and ending at the close of business on
the day of such mailing, or (ii) to register the transfer of or exchange any
Registered Security selected for redemption in whole or in part, except in the
case of any Security to be redeemed in part, the portion thereof not to be
redeemed, or (iii) to exchange any Bearer Security selected for redemption
except, to the extent provided with respect to such Bearer Security, that such
Bearer Security may be exchanged for a Registered Security of like tenor and the
same series, provided that such Registered Security shall be immediately
surrendered for redemption with written instruction for payment consistent with
the provisions of this Indenture or (iv) to issue, register the transfer of or
exchange any Security which, in accordance with its terms, has been surrendered
for repayment at the option of the Holder, except the portion, if any, of such
Security not to be so repaid.

        SECTION 3.6.  MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

        If any mutilated Security or a Security with a mutilated Coupon
appertaining to it is surrendered to the Trustee, subject to the provisions of
this Section 3.6, the Company shall execute and the Trustee shall authenticate
and deliver in exchange therefor a new Security of the same series containing
identical terms and of like principal amount and bearing a number not
contemporaneously outstanding, with Coupons appertaining thereto corresponding
to the Coupons, if any, appertaining to the surrendered Security.

        If there be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security or Coupon,
and (ii) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of notice to
the Company or the Trustee that such Security or Coupon 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 exchange for or in lieu of any
such mutilated, destroyed, lost or stolen Security or in exchange for the
Security to which a destroyed, lost or stolen Coupon appertains with all
appurtenant Coupons not destroyed, lost or stolen, a new Security of the same
series containing identical terms and of like principal amount and bearing a
number not contemporaneously outstanding, with Coupons appertaining thereto
corresponding to the Coupons, if any, appertaining to such destroyed, lost or
stolen Security or to the Security to which such destroyed, lost or stolen
Coupon appertains.



                                       30
<PAGE>   37

        Notwithstanding the foregoing provisions of this Section 3.6, in case
any mutilated, destroyed, lost or stolen Security or Coupon 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 or Coupon; provided, however, that
payment of principal of, any premium or interest on or any Additional Amounts
with respect to any Bearer Securities shall, except as otherwise provided in
Section 10.2, be payable only at an Office or Agency for such Securities located
outside the United States and, unless otherwise provided in or pursuant to this
Indenture, any interest on Bearer Securities and any Additional Amounts with
respect to such interest shall be payable only upon presentation and surrender
of the Coupons appertaining thereto.

        Upon the issuance of any new Security under this Section 3.6, 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, with any Coupons appertaining thereto issued
pursuant to this Section 3.6 in lieu of any destroyed, lost or stolen Security,
or in exchange for a Security to which a destroyed, lost or stolen Coupon
appertains shall constitute a separate obligation of the Company, whether or not
the destroyed, lost or stolen Security and Coupons appertaining thereto or the
destroyed, lost or stolen Coupon shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of such series and any
Coupons, if any, duly issued hereunder.

        The provisions of this Section 3.6, as amended or supplemented pursuant
to this Indenture with respect to particular Securities or generally, shall be
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 or Coupons.

        SECTION 3.7. PAYMENT OF INTEREST AND CERTAIN ADDITIONAL AMOUNTS; RIGHTS
TO INTEREST AND CERTAIN ADDITIONAL AMOUNTS PRESERVED.

        Unless otherwise provided in or pursuant to this Indenture, any interest
on and any Additional Amounts with respect to any Registered Security which
shall be payable, and are punctually paid or duly provided for, on any Interest
Payment Date shall be paid to the Person in whose name such Security (or one or
more Predecessor Securities) is registered as of the close of business on the
Regular Record Date for such interest.

        Unless otherwise provided in or pursuant to this Indenture, any interest
on and any Additional Amounts with respect to any Registered Security which
shall be payable, but shall not be punctually paid or duly provided for, on any
Interest Payment Date for such Registered Security (herein called "Defaulted
Interest") shall forthwith cease to be payable to the Holder thereof on the
relevant Regular Record Date by virtue of having been such Holder; and such
Defaulted Interest may be paid by the Company, at its election, as provided in
Clause (1) or (2) below:



                                       31
<PAGE>   38

               (1) The Company may elect to make payment of any Defaulted
        Interest to the Person in whose name such Registered Security (or a
        Predecessor Security thereof) shall be registered at the close of
        business on a Special Record Date for the payment of such Defaulted
        Interest, which shall be fixed by the Company in the following manner.
        The Company shall notify the Trustee in writing of the amount of
        Defaulted Interest proposed to be paid on such Registered Security, the
        Special Record Date therefor and the date of the proposed payment, and
        at the same time the Company shall deposit with the Trustee an amount of
        money equal to the aggregate amount proposed to be paid in respect of
        such Defaulted Interest or shall make arrangements satisfactory to the
        Trustee for such deposit on or prior to the date of the proposed
        payment, such money when so deposited to be held in trust for the
        benefit of the Person entitled to such Defaulted Interest as provided in
        this clause (1). The Special Record Date for the payment of such
        Defaulted Interest shall be not more than 15 days and not less than 10
        days prior to the date of the proposed payment and not less than 10 days
        after notification to the Trustee of the proposed payment. The Trustee
        shall, in the name and at the expense of the Company, cause notice of
        the proposed payment of such Defaulted Interest and the Special Record
        Date therefor to be mailed, first-class postage prepaid, to the Holder
        of such Registered Security (or a Predecessor Security thereof) at his
        address as it appears in the Security Register not less than 10 days
        prior to such Special Record Date. The Trustee may, in its discretion,
        in the name and at the expense of the Company, cause a similar notice to
        be published at least once in an Authorized Newspaper of general
        circulation in the Borough of Manhattan, The City of New York, but such
        publication shall not be a condition precedent to the establishment of
        such Special Record Date. Notice of the proposed payment of such
        Defaulted Interest and the Special Record Date therefor having been
        mailed as aforesaid, such Defaulted Interest shall be paid to the Person
        in whose name such Registered Security (or a Predecessor Security
        thereof) shall be registered at the close of business on such Special
        Record Date and shall no longer be payable pursuant to the following
        clause (2).

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

        Unless otherwise provided in or pursuant to this Indenture or the
Securities of any particular series pursuant to the provisions of this
Indenture, at the option of the Company, interest on Registered Securities that
bear 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 or by
transfer to an account maintained by the payee with a bank located in the United
States.

        Subject to the foregoing provisions of this Section and Section 3.5,
each Security delivered under this Indenture upon registration of transfer of or
in exchange for or in lieu of any



                                       32
<PAGE>   39

other Security shall carry the rights to interest accrued and unpaid, and to
accrue, which were carried by such other Security.

        In the case of any Registered Security of any series that is convertible
into other securities of the Company or exchangeable for securities of another
issuer, which Registered Security is converted or exchanged after any Regular
Record Date and on or prior to the next succeeding Interest Payment Date (other
than any Registered Security with respect to which the Stated Maturity is prior
to such Interest Payment Date), interest with respect to which the Stated
Maturity is on such Interest Payment Date shall be payable on such Interest
Payment Date notwithstanding such conversion or exchange, and such interest
(whether or not punctually paid or duly provided for) shall be paid to the
Person in whose name that Registered Security (or one or more predecessor
Registered Securities) is registered at the close of business on such Regular
Record Date. Except as otherwise expressly provided in the immediately preceding
sentence, in the case of any Registered Security which is converted or
exchanged, interest with respect to which the Stated Maturity is after the date
of conversion or exchange of such Registered Security shall not be payable.

        SECTION 3.8.  PERSONS DEEMED OWNERS.

        Prior to due presentment of a Registered 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 Registered Security is registered in the
Security Register as the owner of such Registered Security for the purpose of
receiving payment of principal of, any premium and (subject to Sections 3.5 and
3.7) interest on and any Additional Amounts with respect to such Registered
Security and for all other purposes whatsoever, whether or not any payment with
respect to such Registered Security shall be overdue, and none of the Company,
the Trustee or any agent of the Company or the Trustee shall be affected by
notice to the contrary.

        The Company, the Trustee and any agent of the Company or the Trustee may
treat the bearer of any Bearer Security or the bearer of any Coupon as the
absolute owner of such Security or Coupon for the purpose of receiving payment
thereof or on account thereof and for all other purposes whatsoever, whether or
not any payment with respect to such Security or Coupon shall be overdue, and
none of the Company, the Trustee or any agent of the Company or the Trustee
shall be affected by notice to the contrary.

        No Holder of any beneficial interest in any global Security held on its
behalf by a Depository shall have any rights under this Indenture with respect
to such global Security, 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. None of the Company, the Trustee, any
Paying Agent or the Security Registrar will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests of a global Security or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.

        SECTION 3.9.  CANCELLATION.

        All Securities and Coupons surrendered for payment, redemption,
registration of transfer, exchange or conversion or for credit against any
sinking fund payment shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee, and any such Securities and Coupons, as well as
Securities and Coupons surrendered directly to the Trustee for any such purpose,
shall be cancelled promptly by 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 cancelled promptly 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 or pursuant to this Indenture. All cancelled Securities and Coupons held by
the Trustee shall be destroyed by the Trustee, unless by a Company Order the
Company directs their return to it.

        SECTION 3.10.  COMPUTATION OF INTEREST.

        Except as otherwise provided in or pursuant to this Indenture or in any
Security, interest on the Securities shall be computed on the basis of a 360-day
year of twelve 30-day months.

                     SATISFACTION AND DISCHARGE OF INDENTURE

        SECTION 4.1.  SATISFACTION AND DISCHARGE.

        Upon the direction of the Company by a Company Order, this Indenture
shall cease to be of further effect with respect to any series of Securities
specified in such Company Order and any Coupons appertaining thereto, and the
Trustee, on receipt of a Company Order, at the expense of the Company, shall
execute proper instruments acknowledging satisfaction and discharge of this
Indenture as to such series, when

               (1)    either

                      (a) all Securities of such series theretofore
               authenticated and delivered and all Coupons appertaining thereto
               (other than (i) Coupons appertaining to Bearer Securities of such
               series surrendered in exchange for Registered Securities of such
               series and maturing after such exchange whose surrender is not

               cancellation; or

                      (b) all Securities of such series and, in the case of (i)
               or (ii) below, any Coupons appertaining thereto not theretofore
               delivered to the Trustee for cancellation, (i) have become due
               and payable, or (ii) will become due and payable at their Stated

               the Company, 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 such purpose, money in
               the Currency in which such Securities are payable in an amount
               sufficient to pay and discharge the entire indebtedness on such
               Securities and any Coupons appertaining thereto not theretofore
               delivered to the Trustee for cancellation, including the
               principal of, any premium and interest on, and any Additional
               Amounts with respect to such Securities and any Coupons
               appertaining thereto, to the date of such deposit (in the case of
               Securities which have become due and payable) or to the Maturity
               thereof, as the case may be;

               (2) the Company has paid or caused to be paid all other sums
        payable hereunder by the Company with respect to the Outstanding
        Securities of such series and any Coupons appertaining thereto; and

               (3) the Company has delivered to the Trustee an Officer's
        Certificate and an Opinion of Counsel, each stating that all conditions
        precedent herein provided for relating to the satisfaction and discharge
        of this Indenture as to such series 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 such series as to which it is Trustee and if the other conditions
thereto are met.

        Notwithstanding the satisfaction and discharge of this Indenture with
respect to any series of Securities, the obligations of the Company to the
Trustee under Section 6.6 and, if money shall have been deposited with the
Trustee pursuant to subclause (b) of clause (1) of this Section, the obligations
of the Company and the Trustee with respect to the Securities of such series
under Sections 3.5, 3.6, 4.3, 10.2 and 10.3, with respect to the payment of
Additional Amounts, if any, with respect to such Securities as contemplated by
Section 10.4 (but only to the extent that the Additional Amounts payable with
respect to such Securities exceed the amount deposited in respect of such
Additional Amounts pursuant to Section 4.1(1)(b)), and with respect to any
rights to convert or exchange such Securities into securities of the Company or
another issuer shall survive.

        SECTION 4.2.  DEFEASANCE AND COVENANT DEFEASANCE.

               (1) Unless pursuant to Section 3.1, either or both of (i)
        defeasance of the Securities of or within a series under clause (2) of
        this Section 4.2 shall not be applicable with respect to the Securities
        of such series or (ii) covenant defeasance of the Securities of or
        within a series under clause (3) of this Section 4.2 shall not be
        applicable with respect to the Securities of such series, then such
        provisions, together with the other provisions of this Section 4.2 (with
        such modifications thereto as may be specified pursuant to Section 3.1
        with respect to any Securities), shall be applicable to such Securities
        and any Coupons appertaining thereto, and the Company may at its option
        by Board Resolution, at any time, with respect to such Securities and
        any Coupons appertaining thereto, elect to have Section 4.2(2) or
        Section 4.2(3) be applied to such Outstanding Securities and any Coupons
        appertaining thereto upon compliance with the conditions set forth below
        in this Section 4.2.

               (2) Upon the Company's exercise of the above option applicable to
        this Section 4.2(2) with respect to any Securities of or within a
        series, the Company shall be deemed to have been discharged from its
        obligations with respect to such Outstanding Securities and any Coupons
        appertaining thereto on the date the conditions set forth in clause (4)
        of this Section 4.2 are satisfied (hereinafter, "defeasance"). For this
        purpose, such defeasance means that the Company shall be deemed to have
        paid and discharged the entire Indebtedness represented by such
        Outstanding Securities and any Coupons appertaining thereto, which shall
        thereafter be deemed to be "Outstanding" only for the purposes of clause
        (5) of this Section 4.2 and the other Sections of this Indenture
        referred to in clauses (i) and (ii) below, and to have satisfied all of
        its other obligations under such Securities and any Coupons appertaining
        thereto, and this Indenture insofar as such Securities and any Coupons
        appertaining thereto are concerned (and the Trustee, at the expense of
        the Company, shall execute proper instruments acknowledging the same),
        except for the following which shall survive until otherwise terminated
        or discharged hereunder: (i) the rights of Holders of such Outstanding
        Securities and any Coupons appertaining thereto to receive, solely from
        the trust fund described in clause (4) of this Section 4.2 and as more
        fully set forth in such clause, payments in respect of the principal of
        (and premium, if any) and interest, if any, on, and Additional Amounts,
        if any, with respect to, such Securities and any Coupons appertaining
        thereto when such payments are due, and any rights of such Holder to
        convert such Securities into other securities of the Company or exchange
        such Securities for securities of another issuer, (ii) the obligations
        of the Company and the Trustee with respect to such Securities under
        Sections 3.5, 3.6, 10.2 and 10.3 and with respect to the payment of
        Additional Amounts, if any, on such Securities as contemplated by
        Section 10.4 (but only to the extent that the Additional Amounts payable
        with respect to such Securities exceed the amount deposited in respect
        of such Additional Amounts pursuant to Section 4.2(4)(a) below), and
        with respect to any rights to convert such Securities into other
        securities of the Company or exchange such Securities for securities of
        another issuer, (iii) the rights, powers, trusts, duties and immunities
        of the Trustee hereunder and (iv) this Section 4.2. The Company may



                                       36
<PAGE>   43

        exercise its option under this Section 4.2(2) notwithstanding the prior
        exercise of its option under clause (3) of this Section 4.2 with respect
        to such Securities and any Coupons appertaining thereto.

               (3) Upon the Company's exercise of the option to have this
        Section 4.2(3) apply with respect to any Securities of or within a
        series, the Company shall be released from its obligations under
        Sections 10.5 and 10.6, and, to the extent specified pursuant to Section
        3.1(19), any other covenant applicable to such Securities, with respect
        to such Outstanding Securities and any Coupons appertaining thereto, on
        and after the date the conditions set forth in clause (4) of this
        Section 4.2 are satisfied (hereinafter, "covenant defeasance"), and such
        Securities and any Coupons appertaining thereto shall thereafter be
        deemed to be not "Outstanding" for the purposes of any direction,
        waiver, consent or declaration or Act of Holders (and the consequences
        of any thereof) in connection with any such covenant, but shall continue
        to be deemed "Outstanding" for all other purposes hereunder. For this
        purpose, such covenant defeasance means that, with respect to such
        Outstanding Securities and any Coupons appertaining thereto, the Company
        may omit to comply with, and shall have no liability in respect of, any
        term, condition or limitation set forth in any such Section or such
        other covenant, whether directly or indirectly, by reason of any
        reference elsewhere herein to any such Section or such other covenant or
        by reason of reference in any such Section or such other covenant to any
        other provision herein or in any other document and such omission to
        comply shall not constitute a default or an Event of Default under
        Section 5.1(4) or 5.1(8) or otherwise, as the case may be, but, except
        as specified above, the remainder of this Indenture and such Securities
        and Coupons appertaining thereto shall be unaffected thereby.

               (4) The following shall be the conditions to application of
        clause (2) or (3) of this Section 4.2 to any Outstanding Securities of
        or within a series and any Coupons appertaining thereto:

                      (a) The Company shall irrevocably have deposited or caused
               to be deposited with the Trustee (or another trustee satisfying
               the requirements of Section 6.7 who shall agree to comply with
               the provisions of this Section 4.2 applicable to it) as trust
               funds in trust for the purpose of making the following payments,
               specifically pledged as security for, and dedicated solely to,
               the benefit of the Holders of such Securities and any Coupons
               appertaining thereto, (1) an amount in Dollars or in such Foreign
               Currency in which such Securities and any Coupons appertaining
               thereto are then specified as payable at Stated Maturity, or (2)
               Government Obligations applicable to such Securities and Coupons
               appertaining thereto (determined on the basis of the Currency in
               which such Securities and Coupons appertaining thereto are then
               specified as payable at Stated Maturity) which through the
               scheduled payment of principal and interest in respect thereof in
               accordance with their terms will provide, not later than one day
               before the due date of any payment of principal of (and premium,
               if any) and interest, if any, on such Securities and any Coupons
               appertaining thereto, money



                                       37
<PAGE>   44

               in an amount, or (3) a combination thereof, in any case, in an
               amount, sufficient, without consideration of any reinvestment of
               such principal and interest, in the opinion of a nationally
               recognized firm of independent public accountants expressed in a
               written certification thereof delivered to the Trustee, to pay
               and discharge, and which shall be applied by the Trustee (or
               other qualifying trustee) to pay and discharge, (y) the principal
               of (and premium, if any) and interest, if any, on such
               Outstanding Securities and any Coupons appertaining thereto at
               the Stated Maturity of such principal or installment of principal
               or premium or interest and (z) any mandatory sinking fund
               payments or analogous payments applicable to such Outstanding
               Securities and any Coupons appertaining thereto on the days on
               which such payments are due and payable in accordance with the
               terms of this Indenture and of such Securities and any Coupons
               appertaining thereto.

                      (b) Such defeasance or covenant defeasance shall not
               result in a breach or violation of, or constitute a default
               under, this Indenture or any other material agreement or
               instrument to which the Company is a party or by which it is
               bound.

                      (c) No Event of Default or event which with notice or
               lapse of time or both would become an Event of Default with
               respect to such Securities and any Coupons appertaining thereto
               shall have occurred and be continuing on the date of such deposit
               and, with respect to defeasance only, at any time during the
               period ending on the 123rd day after the date of such deposit (it
               being understood that this condition shall not be deemed
               satisfied until the expiration of such period).

                      (d) In the case of an election under clause (2) of this
               Section 4.2, the Company shall have delivered to the Trustee an
               Opinion of Counsel stating that (i) the Company has received from
               the Internal Revenue Service a letter ruling, or there has been
               published by the Internal Revenue Service a Revenue Ruling, or
               (ii) since the date of execution of this Indenture, there has
               been a change in the applicable Federal income tax law, in either
               case to the effect that, and based thereon such opinion shall
               confirm that, the Holders of such Outstanding Securities and any
               Coupons appertaining thereto will not recognize income, gain or
               loss for Federal income tax purposes as a result of such
               defeasance and will be subject to Federal income tax on the same
               amounts, in the same manner and at the same times as would have
               been the case if such defeasance had not occurred.

                      (e) In the case of an election under clause (3) of this
               Section 4.2, the Company shall have delivered to the Trustee an
               Opinion of Counsel to the effect that the Holders of such
               Outstanding Securities and any Coupons appertaining thereto will
               not recognize income, gain or loss for Federal income tax
               purposes as a result of such covenant defeasance and will be
               subject to Federal income tax on the same amounts, in the same
               manner and at the same times as would have been the case if such
               covenant defeasance had not occurred.

                      (f) The Company shall have delivered to the Trustee an
               Opinion of Counsel to the effect that, after the 123rd day after
               the date of deposit, all money and Government Obligations (or
               other property as may be provided pursuant to Section 3.1)
               (including the proceeds thereof) deposited or caused to be
               deposited with the Trustee (or other qualifying trustee) pursuant
               to this clause (4) to be held in trust will not be subject to any
               case or proceeding (whether voluntary or involuntary) in respect
               of the Company under any Federal or State bankruptcy, insolvency,
               reorganization or other similar law, or any decree or order for
               relief in respect of the Company issued in connection therewith.

                      (g) The Company shall have delivered to the Trustee an
               Officer's Certificate and the Company shall have delivered to the
               Trustee an Opinion of Counsel, each stating that all conditions
               precedent to the defeasance or covenant defeasance under clause
               (2) or (3) of this Section 4.2 (as the case may be) have been
               complied with.

                      (h) Notwithstanding any other provisions of this Section
               4.2(4), such defeasance or covenant defeasance shall be effected
               in compliance with any additional or substitute terms, conditions
               or limitations which may be imposed on the Company in connection
               therewith pursuant to Section 3.1.

               (5) Unless otherwise specified in or pursuant to this Indenture
        or any Security, if, after a deposit referred to in Section 4.2(4)(a)
        has been made, (a) the Holder of a Security in respect of which such
        deposit was made is entitled to, and does, elect pursuant to Section 3.1
        or the terms of such Security to receive payment in a Currency other
        than that in which the deposit pursuant to Section 4.2(4)(a) has been
        made in respect of such Security, or (b) a Conversion Event occurs in
        respect of the Foreign Currency in which the deposit pursuant to Section
        4.2(4)(a) has been made, the indebtedness represented by such Security
        and any Coupons appertaining thereto shall be deemed to have been, and
        will be, fully discharged and satisfied through the payment of the
        principal of (and premium, if any), and interest, if any, on, and
        Additional Amounts, if any, with respect to, such Security as the same
        becomes due out of the proceeds yielded by converting (from time to time
        as specified below in the case of any such election) the amount or other
        property deposited in respect of such Security into the Currency in
        which such Security becomes payable as a result of such election or
        Conversion Event based on (x) in the case of payments made pursuant to
        clause (a) above, the applicable market exchange rate for such Currency
        in effect on the second Business Day prior to each payment date, or (y)
        with respect to a Conversion Event, the applicable market exchange rate
        for such Foreign Currency in effect (as nearly as feasible) at the time
        of the Conversion Event.

        The Company shall pay and indemnify the Trustee (or other qualifying
trustee, collectively for purposes of this Section 4.2(5) and Section 4.3, the
"Trustee") against any tax, fee or other charge, imposed on or assessed against
the Government Obligations deposited



                                       39
<PAGE>   46

pursuant to this Section 4.2 or the principal or interest received in respect
thereof other than any such tax, fee or other charge which by law is for the
account of the Holders of such Outstanding Securities and any Coupons
appertaining thereto.

        Anything in this Section 4.2 to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request, any money or Government Obligations (or other property and any proceeds
therefrom) held by it as provided in clause (4) of this Section 4.2 which, in
the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect a defeasance or covenant defeasance, as applicable, in accordance with
this Section 4.2.

        SECTION 4.3.  APPLICATION OF TRUST MONEY.

        Subject to the provisions of the last paragraph of Section 10.3, all
money and Government Obligations (or other property as may be provided pursuant
to Section 3.1) (including the proceeds thereof) deposited with the Trustee
pursuant to Section 4.1 or 4.2 in respect of any Outstanding Securities of any
series and any Coupons appertaining thereto shall be held in trust and applied
by the Trustee, in accordance with the provisions of such Securities and any
Coupons appertaining thereto and this Indenture, to the payment, either directly
or through any Paying Agent (including the Company acting as its own Paying
Agent) as the Trustee may determine, to the Holders of such Securities and any
Coupons appertaining thereto of all sums due and to become due thereon in
respect of principal (and premium, if any) and interest and Additional Amounts,
if any; but such money and Government Obligations need not be segregated from
other funds except to the extent required by law.

                                    REMEDIES

        SECTION 5.1.  EVENTS OF DEFAULT.

        "Event of Default," wherever used herein with respect to Securities of
any series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body),
unless such event is specifically deleted or modified in or pursuant to the
supplemental indenture, Board Resolution or Officer's Certificate establishing
the terms of such Series pursuant to this Indenture:

               (1) default in the payment of any interest on any Security of
        such series, or any Additional Amounts payable with respect thereto,
        when such interest becomes or such Additional Amounts become due and
        payable, and continuance of such default for a period of 30 days; or

               (2) default in the payment of the principal of or any premium on
        any Security of such series, or any Additional Amounts payable with
        respect thereto, when such principal or premium becomes or such

               (4) default in the performance, or breach, of any covenant or
        warranty of the Company in this Indenture or the Securities (other than
        a covenant or warranty a default in the performance or the breach of
        which is elsewhere in this Section specifically dealt with or which has
        been expressly included in this Indenture solely for the benefit of a
        series of Securities other than such series), and continuance of such
        default or breach for a period of 60 days after there has been given, by

        hereafter be created or incurred, shall happen and shall consist, in the
        aggregate, of the default in the payment of $25,000,000 or more in
        principal amount of such Indebtedness at the maturity thereof (after
        giving effect to any applicable grace period) or shall, in the
        aggregate, result in such Indebtedness in principal amount of
        $25,000,000 or more becoming or being declared due and payable prior to
        the date on which it would otherwise become due and payable, and such
        default shall not be cured or such acceleration shall not be rescinded,
        stayed or annulled or, in the case of Indebtedness contested in good
        faith by the Company, a bond, letter of credit, escrow deposit or other

        having been set aside by the Company, in each case within a period of 10
        days after there shall have been given, by registered or certified mail,

        the taking of corporate action by the Company in furtherance of any such
        action; or

               (8) any other Event of Default provided in or pursuant to this
        Indenture with respect to Securities of such series.

        SECTION 5.2.  ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

        If an Event of Default with respect to Securities of any series at the
time Outstanding (other than an Event of Default specified in clause (6) or (7)
of Section 5.1) occurs and is continuing, then the Trustee or the Holders of not
less than 25% in principal amount of the Outstanding Securities of such series
may declare the principal of all the Securities of such series, or such lesser
amount as may be provided for in the Securities of such series, to be due and
payable immediately, by a notice in writing to the Company (and to the Trustee
if given by the Holders), and upon any such declaration such principal or such
lesser amount shall become immediately due and payable.

        If an Event of Default specified in clause (6) or (7) of Section 5.1
occurs, all unpaid principal of and accrued interest on the Outstanding
Securities of that series (or such lesser amount as may be provided for in the
Securities of such series) shall ipso facto become and be



                                       42
<PAGE>   49

immediately due and payable without any declaration or other act on the part of
the Trustee or any Holder of any Security of that series.

        At any time after a declaration of acceleration with respect to the
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 not less than a majority in principal amount of
the Outstanding Securities of such series, by written notice to the Company and
the Trustee, may rescind and annul such declaration and its consequences if

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

                      (a) all overdue installments of any interest on and
               Additional Amounts with respect to all Securities of such series
               and any Coupon appertaining thereto,

                      (b) the principal of and any premium on any Securities of
               such series which have become due otherwise than by such
               declaration of acceleration and interest thereon and any
               Additional Amounts with respect thereto at the rate or rates
               borne by or provided for in such Securities,

                      (c) to the extent that payment of such interest or
               Additional Amounts is lawful, interest upon overdue installments
               of any interest and Additional Amounts at the rate or rates borne
               by or provided for 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 all other amounts due
               the Trustee under Section 6.6; and

               (2) all Events of Default with respect to Securities of such
        series, other than the non-payment of the principal of, any premium and
        interest on, and any Additional Amounts with respect to Securities of
        such series which shall have become due solely by such declaration of
        acceleration, shall 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.

        SECTION 5.3. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
TRUSTEE.

        The Company covenants that if

               (1) default is made in the payment of any installment of interest
        on or any Additional Amounts with respect to any Security or any Coupon
        appertaining thereto



                                       43
<PAGE>   50

        when such interest or Additional Amounts shall have become 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 any
        premium on any Security or any Additional Amounts with respect thereto
        at their Maturity,

the Company shall, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities and any Coupons appertaining thereto,
the whole amount of money then due and payable with respect to such Securities
and any Coupons appertaining thereto, with interest upon the overdue principal,
any premium and, to the extent that payment of such interest shall be legally
enforceable, upon any overdue installments of interest and Additional Amounts at
the rate or rates borne by or provided for in such Securities, and, in addition
thereto, such further amount of money 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 and all other
amounts due to the Trustee under Section 6.6.

        If the Company fails to pay the money it is required to pay the Trustee
pursuant to the preceding paragraph forthwith upon the demand of the Trustee,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the money so due and unpaid, and 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 any Coupons
appertaining thereto and collect the monies 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 and any Coupons appertaining thereto, 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
and any Coupons appertaining thereto 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 such Securities or in aid of the exercise of any power granted
herein or therein, or to enforce any other proper remedy.

        SECTION 5.4.  TRUSTEE MAY FILE PROOFS OF CLAIM.

        In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities of any series or the property of the Company or 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 any overdue principal, premium, interest or
Additional Amounts) shall be entitled and empowered, by intervention in such
proceeding or otherwise,



                                       44
<PAGE>   51

               (1) to file and prove a claim for the whole amount, or such
        lesser amount as may be provided for in the Securities of any applicable
        series, of the principal and any premium, interest and Additional
        Amounts owing and unpaid in respect of the Securities and any Coupons
        appertaining thereto and to 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 or counsel) and of
        the Holders of Securities or any Coupons appertaining thereto allowed in
        such judicial proceeding, and

               (2) to collect and receive any monies 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 of Securities or any Coupons 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 of Securities or any Coupons, to pay to the Trustee any
amount due to 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 6.6.

        Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a Security
or any Coupon any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or Coupons or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder of a
Security or any Coupon in any such proceeding.

        SECTION 5.5. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES
OR COUPONS.

        All rights of action and claims under this Indenture or any of the
Securities or Coupons may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or Coupons 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 or judgment, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, shall be for the ratable benefit of each and every Holder of the
Securities or Coupons in respect of which such judgment has been recovered.

        SECTION 5.6.  APPLICATION OF MONEY COLLECTED.

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



                                       45

               FIRST: To the payment of all amounts due the Trustee and any
        predecessor Trustee under Section 6.6;

               SECOND: To the payment of the amounts then due and unpaid upon
        the Securities and any Coupons for principal and any premium, interest
        and Additional Amounts 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 aggregate amounts due and payable on such
        Securities and Coupons for principal and any premium, interest and
        Additional Amounts, respectively;

               THIRD: The balance, if any, to the Person or Persons entitled
        thereto.

        SECTION 5.7.  LIMITATIONS ON SUITS.

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

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

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

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

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

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

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture or any Security to affect, disturb or prejudice the rights of
any other such Holders or Holders of Securities of any other series, or to
obtain or to seek to obtain priority or preference over any other 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 5.8. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL AND ANY
PREMIUM, INTEREST AND ADDITIONAL AMOUNTS.

        Notwithstanding any other provision in this Indenture, the Holder of any
Security or Coupon shall have the right, which is absolute and unconditional, to
receive payment of the principal of, any premium and (subject to Sections 3.5
and 3.7) interest on, and any Additional Amounts with respect to, such Security
or payment of such Coupon, as the case may be, on the respective Stated Maturity
or Maturities therefor specified in such Security or Coupon (or, in the case of
redemption, on the Redemption Date or, in the case of repayment at the option of
such Holder if provided in or pursuant to this Indenture, on the date such
repayment is due) and to institute suit for the enforcement of any such payment,
and such right shall not be impaired without the consent of such Holder.

        SECTION 5.9.  RESTORATION OF RIGHTS AND REMEDIES.

        If the Trustee or any Holder of a Security or a Coupon 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 the Company, the Trustee and each such Holder shall, subject to any
determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Trustee and each such Holder 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 or Coupons in the last
paragraph of Section 3.6, no right or remedy herein conferred upon or reserved
to the Trustee or to each and every Holder of a Security or a Coupon is intended
to be exclusive of any other right or remedy, and every right and remedy, to the
extent permitted by law, shall 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, to the extent permitted by law, 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 Security or
Coupon 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 any Holder of a Security or a Coupon may be
exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by such Holder, as the case may be.



                                       47
<PAGE>   54

        SECTION 5.12.  CONTROL BY HOLDERS OF SECURITIES.

        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 and any Coupons appertaining thereto, provided that

               (1) such direction shall not be in conflict with any rule of law
        or with this Indenture or with the Securities of such series,

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

               (3) such direction is not unduly prejudicial to the rights of the
        other Holders of Securities of such series not joining in such action.

        SECTION 5.13.  WAIVER OF PAST DEFAULTS.

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

               (1) in the payment of the principal of, any premium or interest
        on, or any Additional Amounts with respect to, any Security of such
        series or any Coupons appertaining thereto, or

               (2) in respect of a covenant or provision hereof which under
        Article 9 cannot be modified or amended without the consent of the
        Holder of each Outstanding Security of such series affected.

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

        SECTION 5.14.  WAIVER OF USURY, STAY OR EXTENSION LAWS.

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

<PAGE>   55

        SECTION 5.15.  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 or
omitted by it as Trustee, the filing by any party litigant in such suit of any
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 5.15 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 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, if any, on or Additional Amounts,
if any, with respect to any Security on or after the respective Stated
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date, and, in the case of repayment, on or after the date
for repayment) or for the enforcement of the right, if any, to convert or
exchange any Security into other securities in accordance with its terms.

        delivery pursuant to Section 3.3 which shall be sufficiently evidenced
        as provided therein) and any resolution of the Board of Directors may be
        sufficiently evidenced by a Board Resolution;

               (3) whenever in the administration of this Indenture the Trustee

        taking, suffering or omitting any action hereunder, the Trustee (unless
        other evidence shall be herein specifically prescribed) may, in the
        absence of bad faith on its part, rely upon an Officer's Certificate;

<PAGE>   56

               (4) the Trustee may consult with counsel and the written advice

        with such request or direction;

Company, in its individual or any other capacity, may become the owner or
pledgee of Securities or Coupons and, subject to Sections 310(b) and 311 of the
Trust Indenture Act, may otherwise deal with the Company with the same rights it
would have if it were not the Trustee, Authenticating Agent, Paying Agent,
Security Registrar or such other Person.

        SECTION 6.5.  MONEY HELD IN TRUST.

        The Company agrees:

               (1) to pay to the Trustee from time to time reasonable
        compensation for all services rendered by the Trustee hereunder (which
        compensation shall not be limited by any provision of law in regard to
        the compensation of a trustee of an express trust);

               (2) except as otherwise expressly provided herein, to reimburse
        the Trustee upon its request for all reasonable expenses, disbursements
        and advances incurred or made by the Trustee in accordance with any
        provision of this Indenture or arising out of or in connection with the
        acceptance or administration of the trust or trusts hereunder (including
        the reasonable compensation and the expenses and disbursements of its
        agents and counsel), except any such expense, disbursement or advance as
        may be attributable to the Trustee's negligence or bad faith; and

               (3) to indemnify the Trustee and its agents, officers, directors
        and employees for, and to hold them harmless against, any loss,
        liability or expense incurred without negligence or bad faith on their
        part, arising out of or in connection with the acceptance or
        administration of the trust or trusts hereunder, including the costs and
        expenses of defending themselves against any claim or liability in
        connection with the exercise or performance of any of their powers or
        duties hereunder, except to the extent that any such loss, liability or
        expense was due to the Trustee's negligence or bad faith.

        As security for the performance of the obligations of the Company under
this Section, the Trustee shall have a lien prior to the Securities of any
series upon all property and funds held or collected by the Trustee as such,

interest on or any Additional Amounts with respect to Securities or any Coupons
appertaining thereto.

        To the extent permitted by law, any compensation or expense incurred by
the Trustee after a default specified in or pursuant to Section 5.1 is intended
to constitute an expense of administration under any then applicable bankruptcy
or insolvency law. "Trustee" for purposes of this Section 6.6 shall include any
predecessor Trustee but the negligence or bad faith of any Trustee shall not
affect the rights of any other Trustee under this Section 6.6.

        The provisions of this Section 6.6 shall survive the satisfaction and
discharge of this Indenture or the earlier resignation or removal of the Trustee
and shall apply with equal force and effect to the Trustee in its capacity as
Authenticating Agent, Paying Agent or Security Registrar.

               Act, any Holder of a Security 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

        applicable requirements of Section 6.9. If, within one year after such
        resignation, removal or incapacity, 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

        successor Trustee with respect to the Securities of any series shall
        have been so appointed by the Company or the Holders of Securities and
        accepted appointment in the manner required by Section 6.9, any Holder
        of a Security 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

        respect to the Securities of one or more (but not all) series, the
        Company, the retiring Trustee and such successor Trustee shall execute
        and deliver an indenture supplemental hereto wherein each successor
        Trustee shall accept such appointment and which (1) shall contain such

        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 notice given to, or received by, or
        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 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 with respect to the Securities of that or those series to
        which the appointment of such successor Trustee relates other than as
        hereinafter expressly set forth, 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 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 such
        successor Trustee, such retiring Trustee, upon payment of its charges

        with respect to the Securities of that or those series to which the
        appointment of such successor Trustee relates, subject to its claim, if
        any, provided for in Section 6.6.

               (3) Upon request of any Person appointed hereunder as a successor
        Trustee, the Company shall execute any and all instruments for more
        fully and certainly vesting in and confirming to such successor Trustee

        SECTION 6.10. 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, shall be the
successor of the Trustee hereunder, 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 6.11.  APPOINTMENT OF AUTHENTICATING AGENT.

        The Trustee may appoint one or more Authenticating Agents acceptable to
the Company with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of that or
those series issued upon original issue, exchange, registration of transfer,
partial redemption or partial repayment or pursuant to Section 3.6, and
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent.

        Each Authenticating Agent must be acceptable to the Company and, except
as provided in or pursuant to this Indenture, shall at all times be a
Corporation that would be permitted by the Trust Indenture Act to act as trustee
under an indenture qualified under the Trust Indenture Act, is authorized under
applicable law and by its charter to act as an Authenticating Agent and has a
combined capital and surplus (computed in accordance with Section 310(a)(2) of
the Trust Indenture Act) of at least $50,000,000. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect specified in this Section.



                                       56
<PAGE>   63

        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 all or substantially all of
the corporate agency or corporate trust business of an Authenticating Agent,
shall be the successor of such Authenticating Agent hereunder, provided such
Corporation shall be otherwise eligible under this Section, without the
execution or filing of any paper or any further act on the part of the Trustee
or the Authenticating Agent.

        An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and 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 the Company. Upon receiving such a notice 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 (i) mail written notice
of such appointment by first-class mail, postage prepaid, to all Holders of
Registered Securities, if any, of the series with respect to which such
Authenticating Agent shall serve, as their names and addresses appear in the
Security Register, and (ii) if Securities of the series are issued as Bearer
Securities, publish notice of such appointment at least once in an Authorized
Newspaper in the place where such successor Authenticating Agent has its
principal office if such office is located outside the United States. Any
successor Authenticating Agent, upon acceptance of its appointment hereunder,
shall become vested with all the 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.

        The Company agrees to pay each Authenticating Agent from time to time
reasonable compensation for its services under this Section. If the Trustee
makes such payments, it shall be entitled to be reimbursed for such payments,
subject to the provisions of Section 6.6.

        The provisions of Sections 3.8, 6.3 and 6.4 shall be applicable to each
Authenticating Agent.

        If an Authenticating Agent is appointed with respect to one or more
series of Securities pursuant to this Section, the Securities of such series may
have endorsed thereon, in addition to or in lieu of the Trustee's certificate of
authentication, an alternate certificate of authentication in substantially the
following form:

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

               (5) to evidence and provide for the acceptance of appointment
        hereunder by a successor Trustee with respect to the Securities of one
        or more series and to add to or change any of the provisions of this
        Indenture as shall be necessary to provide for or facilitate the

        SECTION 9.2.  SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

        With the consent of the Holders of not less than a majority in principal
amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the
Trustee, the Company (when authorized by or pursuant to a Company's Board
Resolution) and the Trustee may enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing in

series; provided, however, that no such supplemental indenture, without the

        reduce the amount of the principal of an Original Issue Discount

        repayment at the option of the Holder, on or after the date for
        repayment), or

               (2) reduce the percentage in principal amount of the Outstanding

        without the consent of the Holder of each Outstanding Security affected
        thereby, or

               (4) make any change that adversely affects the right to convert
        or exchange any Security into or for securities of the Company or other
        securities, (whether or not issued by the Company) cash or property in

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

                                       63
<PAGE>   70

        It shall not be necessary for any Act of Holders of Securities under

indenture, but it shall be sufficient if such Act shall approve the substance
thereof.

        SECTION 9.3.  EXECUTION OF SUPPLEMENTAL INDENTURES.

        As a condition to executing, or accepting the additional trusts created

        Securities of any series authenticated and delivered after the execution
of any supplemental indenture pursuant to this Article may, and shall if
required by the Trustee, bear a notation in form approved by the Trustee as to
any matter provided for in such supplemental indenture. If the Company shall so

opinion of the Trustee and the Company, to any such supplemental indenture may
be prepared and executed by the Company and authenticated and delivered by the
Trustee in exchange for Outstanding Securities of such series.

        SECTION 9.6.  CONFORMITY WITH TRUST INDENTURE ACT.

                                    COVENANTS

        SECTION 10.1. PAYMENT OF PRINCIPAL, ANY PREMIUM, INTEREST AND ADDITIONAL
AMOUNTS.

        The Company covenants and agrees for the benefit of the Holders of the
Securities of each series that it will duly and punctually pay the principal of,
any premium and interest on and any Additional Amounts with respect to the
Securities of such series in accordance with the terms thereof, any Coupons
appertaining thereto and this Indenture. Any interest due on any Bearer Security
on or before the Maturity thereof, and any Additional Amounts payable with
respect to such interest, shall be payable only upon presentation and surrender
of the Coupons appertaining thereto for such interest as they severally mature.

        SECTION 10.2.  MAINTENANCE OF OFFICE OR AGENCY.

        The Company shall maintain in each Place of Payment for any series of
Securities an Office or Agency where Securities of such series (but not Bearer
Securities, except as otherwise provided below, unless such Place of Payment is
located outside the United States) may be presented or surrendered for payment,
where Securities of such series may be surrendered for registration of transfer
or exchange, where Securities of such series that are convertible or
exchangeable may be surrendered for conversion or exchange, and where notices
and demands to or upon the Company in respect of the Securities of such series
relating thereto and this Indenture may be served. If Securities of a series are
issuable as Bearer Securities, the Company shall maintain, subject to any laws
or regulations applicable thereto, an Office or Agency in a Place of Payment for
such series which is located outside the United States where Securities of such
series and any Coupons appertaining thereto may be presented and surrendered for
payment; provided, however, that if the Securities of such series are listed on
The Stock Exchange of the United Kingdom and the Republic of Ireland or the
Luxembourg Stock Exchange or any other stock exchange located outside the United
States and such stock exchange shall so require, the Company shall maintain a
Paying Agent in London, Luxembourg or any other required city located outside
the United States, as the case may be, so long as the Securities of such series
are listed on such exchange. 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 any such required
Office or Agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee, except that Bearer Securities of such
series and any Coupons appertaining thereto may be presented and surrendered for
payment at the place specified for the purpose with respect to such Securities
as provided in or pursuant to this Indenture, and the Company hereby appoints
the Trustee as its agent to receive all such presentations, surrenders, notices
and demands.

        Except as otherwise provided in or pursuant to this Indenture, no
payment of principal, premium, interest or Additional Amounts with respect to
Bearer Securities shall be made at any Office or Agency in the United States or
by check mailed to any address in the United States or



                                       65
<PAGE>   72

by transfer to an account maintained with a bank located in the United States;
provided, however, if amounts owing with respect to any Bearer Securities shall
be payable in Dollars, payment of principal of, any premium or interest on and
any Additional Amounts with respect to any such Security may be made at the
Corporate Trust Office of the Trustee or any Office or Agency designated by the
Company in the Borough of Manhattan, The City of New York, if (but only if)
payment of the full amount of such principal, premium, interest or Additional
Amounts at all offices outside the United States maintained for such purpose by
the Company in accordance with this Indenture is illegal or effectively
precluded by exchange controls or other similar restrictions.

        The Company may also from time to time designate one or more other
Offices or Agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an Office
or Agency in each Place of Payment for Securities of any series for such
purposes. The Company shall give prompt written notice to the Trustee of any
such designation or rescission and of any change in the location of any such
other Office or Agency. Unless otherwise provided in or pursuant to this
Indenture, the Company hereby designates as the Place of Payment for each series
of Securities the Borough of Manhattan, The City of New York, and initially
appoints the Corporate Trust Office of the Trustee as the Office or Agency of
the Company in the Borough of Manhattan, The City of New York for such purpose.
The Company may subsequently appoint a different Office or Agency in the Borough
of Manhattan, The City of New York for the Securities of any series.

        Unless otherwise specified with respect to any Securities pursuant to
Section 3.1, if and so long as the Securities of any series (i) are denominated
in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long
as it is required under any other provision of this Indenture, then the Company
will maintain with respect to each such series of Securities, or as so required,
at least one exchange rate agent.

        SECTION 10.3.  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 shall, on or before each due date of the
principal of, any premium or interest on or Additional Amounts with respect to
any of the Securities of such series, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 3.1 for the Securities of such series) sufficient to pay the principal
or any premium, interest or Additional Amounts so becoming due until such sums
shall be paid to such Persons or otherwise disposed of as herein provided, and
shall 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 shall, on or prior to each due date of the principal of, any
premium or interest on or any Additional Amounts with respect to any Securities
of such series, deposit with any Paying



                                       66
<PAGE>   73

Agent a sum (in the currency or currencies, currency unit or units or composite
currency or currencies described in the preceding paragraph) sufficient to pay
the principal or any premium, interest or Additional Amounts so becoming due,
such sum to be held in trust for the benefit of the Persons entitled thereto,
and (unless such Paying Agent is the Trustee) the Company will promptly notify
the Trustee of its action or failure so to act.

        The Company shall 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 shall:

               (1) hold all sums held by it for the payment of the principal of,
        any premium or interest on or any Additional Amounts with respect to
        Securities of such 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 provided in or pursuant to this Indenture;

               (2) give the Trustee notice of any default by the Company (or any
        other obligor upon the Securities of such series) in the making of any
        payment of principal, any premium or interest on or any Additional
        Amounts with respect to the Securities of such 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 terms 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 sums.

        Except as otherwise provided herein or pursuant hereto, 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, any premium or interest on or any
Additional Amounts with respect to any Security of any series or any Coupon
appertaining thereto and remaining unclaimed for two years after such principal
or any such premium or interest or any such Additional Amounts shall have 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 or any Coupon appertaining thereto 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 an Authorized Newspaper in each Place of Payment for such
series or to be mailed to Holders of Registered Securities of such series, or
both, notice that such money remains unclaimed and that,



                                       67
<PAGE>   74

after a date specified therein, which shall not be less than 30 days from the
date of such publication or mailing nor shall it be later than two years after
such principal and any premium or interest or Additional Amounts shall have
become due and payable, any unclaimed balance of such money then remaining will
be repaid to the Company.

        SECTION 10.4.  ADDITIONAL AMOUNTS.

        If any Securities of a series provide for the payment of Additional
Amounts, the Company agrees to pay to the Holder of any such Security or any
Coupon appertaining thereto Additional Amounts as provided in or pursuant to
this Indenture or such Securities. Whenever in this Indenture there is
mentioned, in any context, the payment of the principal of or any premium or
interest on, or in respect of, any Security of any series or any Coupon or the
net proceeds received on the sale or exchange of any Security of any series,
such mention shall be deemed to include mention of the payment of Additional
Amounts provided by the terms of such series established hereby or pursuant
hereto to the extent that, in such context, Additional Amounts are, were or
would be payable in respect thereof pursuant to such terms, and express mention
of the payment of Additional Amounts (if applicable) in any provision hereof
shall not be construed as excluding Additional Amounts in those provisions
hereof where such express mention is not made.

        Except as otherwise provided in or pursuant to this Indenture or the
Securities of the applicable series, if the Securities of a series provide for
the payment of Additional Amounts, at least 10 days prior to the first Interest
Payment Date with respect to such series of Securities (or if the Securities of
such series shall not bear interest prior to Maturity, the first day on which a
payment of principal is made), and at least 10 days prior to each date of
payment of principal or interest if there has been any change with respect to
the matters set forth in the below-mentioned Officer's Certificate, the Company
shall furnish to the Trustee and the principal Paying Agent or Paying Agents, if
other than the Trustee, an Officer's Certificate instructing the Trustee and
such Paying Agent or Paying Agents whether such payment of principal of and
premium, if any, or interest on the Securities of such series shall be made to
Holders of Securities of such series or the Coupons appertaining thereto who are
United States Aliens without withholding for or on account of any tax,
assessment or other governmental charge described in the Securities of such
series. If any such withholding shall be required, then such Officer's
Certificate shall specify by country the amount, if any, required to be withheld
on such payments to such Holders of Securities or Coupons, and the Company
agrees to pay to the Trustee or such Paying Agent the Additional Amounts
required by the terms of such Securities. The Company covenants to indemnify the
Trustee and any Paying Agent for, and to hold them harmless against, any loss,
liability or expense reasonably incurred without negligence or bad faith on
their part arising out of or in connection with actions taken or omitted by any
of them in reliance on any Officer's Certificate furnished pursuant to this
Section 10.4.

        SECTION 10.5.  LIMITATION ON MORTGAGES AND LIENS.

        The Company will not at any time directly or indirectly issue, assume,
guarantee or permit to exist any indebtedness secured by a mortgage, pledge,
lien or other encumbrance (any



                                       68
<PAGE>   75

mortgage, pledge, lien or other encumbrance being hereinafter in this Section
referred to as a "lien") on any of its property or assets or any property or
assets of a Restricted Subsidiary, whether now owned or hereafter acquired,
without making effective provisions whereby the Securities then outstanding
(and, if the Company so elects, any other indebtedness ranking on a parity with
the Securities) shall be equally and ratably secured with any such secured
indebtedness, so long as any such other indebtedness shall be secured; provided,
however, that the foregoing covenant shall not be applicable to the following:

               (1) liens in existence on the date of this Indenture; or

               (2) liens on real estate (including liens existing in respect of
        such real estate at the time of acquisition thereof) securing
        indebtedness in an amount not in excess of 100% of the fair value of the
        real estate at the time of creation of such indebtedness (as determined
        by the Board of Directors); or

               (3) liens arising from the acquisition of a business as a going
        concern (whether by merger, acquisition of a controlling stock interest,
        acquisition of assets or otherwise) or to which assets acquired by the
        Company or a Restricted Subsidiary in partial or complete satisfaction
        of secured indebtedness are subject; or

               (4) liens to secure the extension, renewal or replacement of any
        indebtedness secured by any of the liens referred to in (1), (2) or (3)
        above, provided that there shall not be an increase in the amount of
        indebtedness secured by such extension, renewal or replacement; or

               (5) liens of taxes or assessments or governmental charges or
        levies not then due and delinquent or the validity of which is being
        contested in good faith or which are less than $10,000,000 in amount;
        pledges or deposits to secure public or statutory obligations including
        liens and deposits required or provided for under state insurance laws
        and similar regulatory statutes; materialmen's, mechanics', carrier's,
        workmen's, repairmen's or other like liens, and pledges or deposits made
        in the ordinary course of business to obtain the release of such liens;
        liens created by or resulting from any litigation or legal proceeding
        which is being contested in good faith by appropriate proceedings or
        which involve claims of less than $10,000,000; deposits to secure (or in
        lieu of) surety, stay, appeal or customs bonds; deposits to secure the
        payment of taxes, assessments, customs duties or other similar charges;
        landlords liens on property held under lease; and any other liens
        similar to those described in this clause (5), the existence of which
        does not, in the opinion of the Company, materially impair the use by
        the Company or the Restricted Subsidiary of the affected property in the
        operation of its business, or the value of such property for the purpose
        of such business.

        SECTION 10.6. LIMITATION UPON SALES OF CAPITAL STOCK OF RESTRICTED
SUBSIDIARIES.

        The Company will not sell, transfer or otherwise dispose of (except to a
Restricted Subsidiary), and it will not permit any Restricted Subsidiary to
sell, transfer or otherwise dispose of (except to the Company or to a Restricted
Subsidiary), any shares of Capital Stock of a Restricted Subsidiary, unless the
entire Capital Stock of such Restricted Subsidiary at the time owned by the
Company and its Restricted Subsidiaries shall be disposed of at the same time
for a consideration consisting of cash or other property, which, in the opinion
of the Board of Directors, is at least equal to the fair value thereof.

        For the purposes of this Indenture, "Restricted Subsidiary" shall mean a
Subsidiary including Subsidiaries of any Subsidiary, which meets any of the
following conditions:

               (1) the Company's and its other Subsidiaries' investments in and
        advances to the Subsidiary exceed 10% of the total assets of the Company
        and its Subsidiaries consolidated as of the end of the most recently
        completed fiscal year; or

               (2) the Company's and its other Subsidiaries' proportionate share
        of the total assets (after inter-company eliminations) of the Subsidiary
        exceeds 10% of the total assets of the Company and its Subsidiaries
        consolidated as of the end of the most recently completed fiscal year;
        or

               (3) the Company's and its other Subsidiaries' equity in the
        income from continuing operations before income taxes, extraordinary
        items and cumulative effect of a change in accounting principle of the
        Subsidiary exceeds 10% of such income of the Company and its
        Subsidiaries consolidated for the most recently completed fiscal year.

        For purposes of making the prescribed income test in clause (3) of the
preceding sentence, when a loss has been incurred by either the Company and its
Subsidiaries consolidated or the tested Subsidiary, but not both, the equity in
the income or loss of the tested subsidiary shall be excluded from the income of
the Company and its Subsidiaries consolidated for purposes of the computation
and if income of the Company and its Subsidiaries consolidated for the most
recent fiscal year is at least 10% lower than the average of the income for the
last five years, such average income shall be substituted for purposes of the
computation and any loss years shall be omitted for purposes of computing
average income.

        SECTION 10.7.  CORPORATE EXISTENCE.

        Subject to Article 8, the Company shall 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 of its Restricted Subsidiaries and their respective
rights (charter and statutory) and franchises; provided, however, that the
foregoing shall not obligate the Company or any of its Restricted Subsidiaries
to preserve any such right or franchise if the Company or any such Restricted
Subsidiary shall determine that the preservation thereof is no longer desirable
in the conduct of its business or the



                                       70
<PAGE>   77

business of such Restricted Subsidiary and that the loss thereof is not
disadvantageous in any material respect to any Holder.

        SECTION 10.8.  WAIVER OF CERTAIN COVENANTS.

        The Company may omit in any particular instance to comply with any term,
provision or condition set forth in Section 10.5, 10.6 or 10.7 with respect to
the Securities of any series if before the time for such compliance the Holders
of at least a majority in principal amount of the Outstanding Securities of such
series, by Act of such Holders, either shall waive such compliance in such
instance or generally shall have waived 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 10.9. COMPANY STATEMENT AS TO COMPLIANCE; NOTICE OF CERTAIN
DEFAULTS.

               (1) The Company shall deliver to the Trustee, within 120 days
        after the end of each fiscal year, a written statement (which need not
        be contained in or accompanied by an Officer's Certificate) signed by
        the principal executive officer, the principal financial officer or the
        principal accounting officer of the Company, stating that

                      (a) a review of the activities of the Company during such
               year and of its performance under this Indenture has been made
               under his or her supervision, and

                      (b) to the best of his or her knowledge, based on such
               review, (a) the Company has complied with all the conditions and
               covenants imposed on it under this Indenture throughout such
               year, or, if there has been a default in the fulfillment of any
               such condition or covenant, specifying each such default known to
               him or her and the nature and status thereof, and (b) no event
               has occurred and is continuing which is, or after notice or lapse
               of time or both would become, an Event of Default, or, if such an
               event has occurred and is continuing, specifying each such event
               known to him and the nature and status thereof.

               (2) The Company shall deliver to the Trustee, within five days
        after the occurrence thereof, written notice of any Event of Default or
        any event which after notice or lapse of time or both would become an
        Event of Default pursuant to clause (4) of Section 5.1.

               (3) The Trustee shall have no duty to monitor the Company's
        compliance with the covenants contained in this Article 10 other than as
        specifically set forth in this Section 10.9.

                            REDEMPTION OF SECURITIES

        SECTION 11.1.  APPLICABILITY OF ARTICLE.

        Redemption of Securities of any series at the option of the Company as
permitted or required by the terms of such Securities shall be made in
accordance with the terms of such Securities and (except as otherwise provided
herein or pursuant hereto) this Article.

        SECTION 11.2.  ELECTION TO REDEEM; NOTICE TO TRUSTEE.

        The election of the Company to redeem any Securities shall be evidenced
by or pursuant to a Board Resolution. In case of any redemption at the election
of the Company of (a) less than all of the Securities of any series or (b) all
of the Securities of any series, with the same issue date, interest rate or
formula, Stated Maturity and other terms, the Company shall, at least 60 days
prior to the Redemption Date fixed by the Company (unless a shorter notice shall
be satisfactory to the Trustee), notify the Trustee of such Redemption Date and
of the principal amount of Securities of such series to be redeemed.

        SECTION 11.3.  SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

        If less than all of the Securities of any series with the same issue
date, interest rate or formula, Stated Maturity and other terms 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 of the principal amount of Registered
Securities of such series; provided, however, that no such partial redemption
shall reduce the portion of the principal amount of a Registered Security of
such series not redeemed to less than the minimum denomination for a Security of
such series established herein or pursuant hereto.

        The Trustee shall promptly notify the Company and the Security Registrar
(if other than itself) 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 of such Securities which has been or is to be redeemed.

        Unless otherwise specified in or pursuant to this Indenture or the
Securities of any series, if any Security selected for partial redemption is
converted into other securities of the Company or exchanged for securities of
another issuer in part before termination of the conversion or exchange right
with respect to the portion of the Security so selected, the converted portion
of



                                       72
<PAGE>   79

such Security shall be deemed (so far as may be) to be the portion selected for
redemption. Securities which have been converted or exchanged during a selection
of Securities to be redeemed shall be treated by the Trustee as Outstanding for
the purpose of such selection.

        SECTION 11.4.  NOTICE OF REDEMPTION.

        Notice of redemption shall be given in the manner provided in Section
1.6, not less than 30 nor more than 60 days prior to the Redemption Date, unless
a shorter period is specified in the Securities to be redeemed, to the Holders
of Securities to be redeemed. Failure to give notice by mailing in the manner
herein provided to the Holder of any Registered Securities designated for
redemption as a whole or in part, or any defect in the notice to any such
Holder, shall not affect the validity of the proceedings for the redemption of
any other Securities or portion thereof.

        Any notice that is mailed to the Holder of any Registered Securities in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not such Holder receives the notice.

        All notices of redemption shall state:

               (1) the Redemption Date,

               (2) the Redemption Price,

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

               (4) in case any Security is to be redeemed in part only, the
        notice which relates to such Security shall state that on and after the
        Redemption Date, upon surrender of such Security, the Holder of such
        Security will receive, without charge, a new Security or Securities of
        authorized denominations for the principal amount thereof remaining
        unredeemed,

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

               (6) the place or places where such Securities, together (in the
        case of Bearer Securities) with all Coupons appertaining thereto, if
        any, maturing after the Redemption Date, are to be surrendered for
        payment of the Redemption Price and any accrued interest and Additional
        Amounts pertaining thereto,

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



                                       73
<PAGE>   80

               (8) that, unless otherwise specified in such notice, Bearer
        Securities of any series, if any, surrendered for redemption must be
        accompanied by all Coupons maturing subsequent to the date fixed for
        redemption or the amount of any such missing Coupon or Coupons will be
        deducted from the Redemption Price, unless security or indemnity
        satisfactory to the Company, the Trustee and any Paying Agent is
        furnished,

               (9) if Bearer Securities of any series are to be redeemed and no
        Registered Securities of such series are to be redeemed, and if such
        Bearer Securities may be exchanged for Registered Securities not subject
        to redemption on the Redemption Date pursuant to Section 3.5 or
        otherwise, the last date, as determined by the Company, on which such
        exchanges may be made,

               (10) in the case of Securities of any series that are convertible
        into Common Stock of the Company or exchangeable for other securities,
        the conversion or exchange price or rate, the date or dates on which the
        right to convert or exchange the principal of the Securities of such
        series to be redeemed will commence or terminate and the place or places
        where such Securities may be surrendered for conversion or exchange, and

               (11) the CUSIP number or the Euroclear or the Cedel reference
        numbers of such Securities, if any (or any other numbers used by a
        Depository to identify such Securities).

        A notice of redemption published as contemplated by Section 1.6 need not
identify particular Registered Securities to be redeemed.

        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 11.5.  DEPOSIT OF REDEMPTION PRICE.

        On or prior to any Redemption Date, the Company shall deposit, with
respect to the Securities of any series called for redemption pursuant to
Section 11.4, 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 10.3) an amount of money in the applicable Currency sufficient to pay
the Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date, unless otherwise specified pursuant to Section 3.1 or in the
Securities of such series) any accrued interest on and Additional Amounts with
respect thereto, all such Securities or portions thereof which are to be
redeemed on that date.

        SECTION 11.6.  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



                                       74
<PAGE>   81

Redemption Price and accrued interest) such Securities shall cease to bear
interest and the Coupons for such interest appertaining to any Bearer Securities
so to be redeemed, except to the extent provided below, shall be void. Upon
surrender of any such Security for redemption in accordance with said notice,
together with all Coupons, if any, appertaining thereto maturing after the
Redemption Date, such Security shall be paid by the Company at the Redemption
Price, together with any accrued interest and Additional Amounts to the
Redemption Date; provided, however, that, except as otherwise provided in or
pursuant to this Indenture or the Bearer Securities of such series, installments
of interest on Bearer Securities whose Stated Maturity is on or prior to the
Redemption Date shall be payable only upon presentation and surrender of Coupons
for such interest (at an Office or Agency located outside the United States
except as otherwise provided in Section 10.2), and provided, further, that,
except as otherwise specified in or pursuant to this Indenture or the Registered
Securities of such series, installments of interest on Registered Securities
whose Stated Maturity 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 Regular Record Dates therefor
according to their terms and the provisions of Section 3.7.

        If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant Coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing Coupons, or the surrender of such missing
Coupon or Coupons may be waived by the Company and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless. If thereafter the Holder of such Security
shall surrender to the Trustee or any Paying Agent any such missing Coupon in
respect of which a deduction shall have been made from the Redemption Price,
such Holder shall be entitled to receive the amount so deducted; provided,
however, that any interest or Additional Amounts represented by Coupons shall be
payable only upon presentation and surrender of those Coupons at an Office or
Agency for such Security located outside of the United States except as
otherwise provided in Section 10.2.

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

        SECTION 11.7.  SECURITIES REDEEMED IN PART.

        Any Registered Security which is to be redeemed only in part shall be
surrendered at any Office or Agency for such Security (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 Registered Security or Securities of the
same series, containing identical terms and provisions, of any authorized
denomination as requested by such Holder in aggregate principal amount equal to
and in exchange for the unredeemed portion of the



                                       75

principal of the Security so surrendered. If a Security in global form is so
surrendered, the Company shall execute, and the Trustee shall authenticate and
deliver to the U.S. Depository or other Depository for such Security in global
form as shall be specified in the Company Order with respect thereto to the
Trustee, without service charge, a new Security in global form in a denomination
equal to and in exchange for the unredeemed portion of the principal of the
Security in global form so surrendered.

                                   ARTICLE 12

                                  SINKING FUNDS

        SECTION 12.1.  APPLICABILITY OF ARTICLE.

        The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of a series, except as otherwise permitted or
required in or pursuant to this Indenture or any Security of such series issued
pursuant to this Indenture.

        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 such series is herein referred to as an "optional sinking
fund payment". If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided
in Section 12.2. 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 and this Indenture.

        SECTION 12.2.  SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

        The Company may, in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of any series to be made pursuant to the
terms of such Securities (1) deliver Outstanding Securities of such series
(other than any of such Securities previously called for redemption or any of
such Securities in respect of which cash shall have been released to the
Company), together in the case of any Bearer Securities of such series with all
unmatured Coupons appertaining thereto, and (2) apply as a credit Securities of
such series which have been redeemed either at the election of the Company
pursuant to the terms of such series of Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, provided that such series of 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. If, as a result of the delivery or credit
of Securities of any series in lieu of cash payments pursuant to this Section
12.2, the principal amount of Securities of such series to be redeemed in order
to satisfy the remaining sinking fund payment shall be less than $100,000, the
Trustee need not call Securities of such series for redemption, except upon
Company Request, and such cash payment shall be held by the Trustee or a Paying
Agent and applied to the next succeeding sinking fund payment,



                                       76
<PAGE>   83

provided, however, that the Trustee or such Paying Agent shall at the request of
the Company from time to time pay over and deliver to the Company any cash
payment so being held by the Trustee or such Paying Agent upon delivery by the
Company to the Trustee of Securities of that series purchased by the Company
having an unpaid principal amount equal to the cash payment requested to be
released to the Company.

        SECTION 12.3.  REDEMPTION OF SECURITIES FOR SINKING FUND.

        Not less than 75 days prior to each sinking fund payment date for any
series of Securities, the Company shall deliver to the Trustee an Officer's
Certificate specifying the amount of the next ensuing mandatory sinking fund
payment for that series pursuant to the terms of that series, the portion
thereof, if any, which is to be satisfied by payment of cash and the portion
thereof, if any, which is to be satisfied by delivering and crediting of
Securities of that series pursuant to Section 12.2, and the optional amount, if
any, to be added in cash to the next ensuing mandatory sinking fund payment, and
will also deliver to the Trustee any Securities to be so credited and not
theretofore delivered. If such Officer's Certificate shall specify an optional
amount to be added in cash to the next ensuing mandatory sinking fund payment,
the Company shall thereupon be obligated to pay the amount therein specified.
Not less than 60 days before each such sinking fund payment date the Trustee
shall select the Securities to be redeemed upon such sinking fund payment date
in the manner specified in Section 11.3 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 11.4. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 11.6 and 11.7.

                                   ARTICLE 13

                       REPAYMENT AT THE OPTION OF HOLDERS

        SECTION 13.1.  APPLICABILITY OF ARTICLE.

        Securities of any series which are repayable at the option of the
Holders thereof before their Stated Maturity shall be repaid in accordance with
the terms of the Securities of such series. The repayment of any principal
amount of Securities pursuant to such option of the Holder to require repayment
of Securities before their Stated Maturity, for purposes of Section 3.9, shall
not operate as a payment, redemption or satisfaction of the Indebtedness
represented by such Securities unless and until the Company, at its option,
shall deliver or surrender the same to the Trustee with a directive that such
Securities be cancelled. Notwithstanding anything to the contrary contained in
this Section 13.1, in connection with any repayment of Securities, the Company
may arrange for the purchase of any Securities by an agreement with one or more
investment bankers or other purchasers to purchase such Securities by paying to
the Holders of such Securities on or before the close of business on the
repayment date an amount not less than the repayment price payable by the
Company on repayment of such Securities, and the obligation of the Company to
pay the repayment price of such Securities shall be satisfied and discharged to
the extent such payment is so paid by such purchasers.

                        SECURITIES IN FOREIGN CURRENCIES

        SECTION 14.1.  APPLICABILITY OF ARTICLE.

        Whenever this Indenture provides for (i) any action by, or the
determination of any of the rights of, Holders of Securities of any series in
which not all of such Securities are denominated in the same Currency, or (ii)
any distribution to Holders of Securities, in the absence of any provision to
the contrary in the form of Security of any particular series or pursuant to
this Indenture or the Securities, any amount in respect of any Security
denominated in a Currency other than Dollars shall be treated for any such
action or distribution as that amount of Dollars that could be obtained for such
amount on such reasonable basis of exchange and as of the record date with
respect to Registered Securities of such series (if any) for such action,
determination of rights or distribution (or, if there shall be no applicable
record date, such other date reasonably proximate to the date of such action,
determination of rights or distribution) as the Company may specify in a written
notice to the Trustee.

                        MEETINGS OF HOLDERS OF SECURITIES

        SECTION 15.1.  PURPOSES FOR WHICH MEETINGS MAY BE CALLED.

        A meeting of Holders of Securities of any series may be called at any
time and from time to time pursuant to this Article to make, give or take any
request, demand, authorization, direction, notice, consent, waiver or other Act
provided by this Indenture to be made, given or taken by Holders of Securities
of such series.

        SECTION 15.2.  CALL, NOTICE AND PLACE OF MEETINGS.

               (1) The Trustee may at any time call a meeting of Holders of
        Securities of any series for any purpose specified in Section 15.1, to
        be held at such time and at such place in the Borough of Manhattan, The
        City of New York, or, if Securities of such series have been issued in
        whole or in part as Bearer Securities, in London or in such place
        outside the United States as the Trustee shall determine. Notice of
        every meeting of Holders of Securities of any series, setting forth the
        time and the place of such meeting and in general terms the action
        proposed to be taken at such meeting, shall be given, in the manner
        provided in Section 1.6, not less than 21 nor more than 180 days prior
        to the date fixed for the meeting.

               (2) In case at any time the Company (by or pursuant to a Board
        Resolution) or the Holders of at least 10% in principal amount of the
        Outstanding Securities of any series shall have requested the Trustee to
        call a meeting of the Holders of Securities of such series for any
        purpose specified in Section 15.1, by written request setting forth in



                                       78
<PAGE>   85

        reasonable detail the action proposed to be taken at the meeting, and
        the Trustee shall not have mailed notice of or made the first
        publication of the notice of such meeting within 21 days after receipt
        of such request (whichever shall be required pursuant to Section 1.6) or
        shall not thereafter proceed to cause the meeting to be held as provided
        herein, then the Company or the Holders of Securities of such series in
        the amount above specified, as the case may be, may determine the time
        and the place in the Borough of Manhattan, The City of New York, or, if
        Securities of such series are to be issued as Bearer Securities, in
        London for such meeting and may call such meeting for such purposes by
        giving notice thereof as provided in clause (1) of this Section.

        SECTION 15.3.  PERSONS ENTITLED TO VOTE AT MEETINGS.

        To be entitled to vote at any meeting of Holders of Securities of any
series, a Person shall be (1) a Holder of one or more Outstanding Securities of
such series, or (2) a Person appointed by an instrument in writing as proxy for
a Holder or Holders of one or more Outstanding Securities of such series by such
Holder or Holders. The only Persons who shall be entitled to be present or to
speak at any meeting of Holders of Securities of any series shall be the Persons
entitled to vote at such meeting and their counsel, any representatives of the
Trustee and its counsel and any representatives of the Company and its counsel.

        SECTION 15.4.  QUORUM; ACTION.

        The Persons entitled to vote a majority in principal amount of the
Outstanding Securities of a series shall constitute a quorum for any meeting of
Holders of Securities of such series. In the absence of a quorum within 30
minutes after the time appointed for any such meeting, the meeting shall, if
convened at the request of Holders of Securities of such series, be dissolved.
In any other case the meeting may be adjourned for a period of not less than 10
days as determined by the chairman of the meeting prior to the adjournment of
such meeting. In the absence of a quorum at any reconvened meeting, such
reconvened meeting may be further adjourned for a period of not less than 10
days as determined by the chairman of the meeting prior to the adjournment of
such reconvened meeting. Notice of the reconvening of any adjourned meeting
shall be given as provided in Section 15.2(1), except that such notice need be
given only once not less than five days prior to the date on which the meeting
is scheduled to be reconvened. Notice of the reconvening of an adjourned meeting
shall state expressly the percentage, as provided above, of the principal amount
of the Outstanding Securities of such series which shall constitute a quorum.

        Except as limited by the proviso to Section 9.2, any resolution
presented to a meeting or adjourned meeting duly reconvened at which a quorum is
present as aforesaid may be adopted only by the affirmative vote of the Holders
of a majority in principal amount of the Outstanding Securities of that series;
provided, however, that, except as limited by the proviso to Section 9.2, any
resolution with respect to any request, demand, authorization, direction,
notice, consent, waiver or other Act which this Indenture expressly provides may
be made, given or taken by the Holders of a specified percentage, which is less
than a majority, in principal amount of the Outstanding Securities of a series
may be adopted at a meeting or an adjourned meeting duly



                                       79
<PAGE>   86

reconvened and at which a quorum is present as aforesaid by the affirmative vote
of the Holders of such specified percentage in principal amount of the
Outstanding Securities of such series.

        Any resolution passed or decision taken at any meeting of Holders of
Securities of any series duly held in accordance with this Section shall be
binding on all the Holders of Securities of such series and the Coupons
appertaining thereto, whether or not such Holders were present or represented at
the meeting.

        SECTION 15.5. DETERMINATION OF VOTING RIGHTS; CONDUCT AND ADJOURNMENT OF
MEETINGS.

               (1) Notwithstanding any other provisions of this Indenture, the
        Trustee may make such reasonable regulations as it may deem advisable
        for any meeting of Holders of Securities of such series in regard to
        proof of the holding of Securities of such series and of the appointment
        of proxies and in regard to the appointment and duties of inspectors of
        votes, the submission and examination of proxies, certificates and other
        evidence of the right to vote, and such other matters concerning the
        conduct of the meeting as it shall deem appropriate. Except as otherwise
        permitted or required by any such regulations, the holding of Securities
        shall be proved in the manner specified in Section 1.4 and the
        appointment of any proxy shall be proved in the manner specified in
        Section 1.4 or by having the signature of the person executing the proxy
        witnessed or guaranteed by any trust company, bank or banker authorized
        by Section 1.4 to certify to the holding of Bearer Securities. Such
        regulations may provide that written instruments appointing proxies,
        regular on their face, may be presumed valid and genuine without the
        proof specified in Section 1.4 or other proof.

               (2) The Trustee shall, by an instrument in writing, appoint a
        temporary chairman of the meeting, unless the meeting shall have been
        called by the Company or by Holders of Securities as provided in Section
        15.2(2), in which case the Company or the Holders of Securities of the
        series calling the meeting, as the case may be, shall in like manner
        appoint a temporary chairman. A permanent chairman and a permanent
        secretary of the meeting shall be elected by vote of the Persons
        entitled to vote a majority in principal amount of the Outstanding
        Securities of such series represented at the meeting.

               (3) At any meeting, each Holder of a Security of such series or
        proxy shall be entitled to one vote for each $1,000 principal amount of
        Securities of such series held or represented by him; provided, however,
        that no vote shall be cast or counted at any meeting in respect of any
        Security challenged as not Outstanding and ruled by the chairman of the
        meeting to be not Outstanding. The chairman of the meeting shall have no
        right to vote, except as a Holder of a Security of such series or proxy.

               (4) Any meeting of Holders of Securities of any series duly
        called pursuant to Section 15.2 at which a quorum is present may be
        adjourned from time to time by Persons entitled to vote a majority in
        principal amount of the Outstanding Securities of such series
        represented at the meeting; and the meeting may be held as so adjourned
        without further notice.

        SECTION 15.6.  COUNTING VOTES AND RECORDING ACTION OF MEETINGS.

        The vote upon any resolution submitted to any meeting of Holders of
Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them. The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in triplicate of all votes cast at the meeting. A record, at least in
triplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 15.2 and, if
applicable, Section 15.4. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

principal amount of Debt Securities (the "Debt Securities") of SAFECO
Corporation (the "Company") pursuant to the Company's Registration Statement on
Form S-3 filed with the Securities and Exchange Commission on the date hereof
(the "Registration Statement").

        We have examined the Registration Statement and such other documents
and records of the Company. certificates of public officials, and other
documents as we have deemed necessary or appropriate for the purposes of this
opinion. Capitalized terms used but not otherwise defined herein have the
respective meanings assigned to such terms in the registration Statement.

        Based upon the foregoing, we are of the opinion that, when the
following events have occurred:

        (a)  the Registration Statement and any amendments or supplements
thereto have been filed, and the Registration Statement has become effective;

        (b)  the Indenture has been duly executed and delivered by the Company
and the Trustee;

        (c)  the terms of the Debt Securities and their issue and sale have
been duly established in conformity with the Indenture; and

        (d)  the due execution by the Company and authentication and delivery by
the Trustee of the Debt Securities, and the issuance and sale thereof by the
Company as contemplated by the Registration Statement;

the Debt Securities will constitute in the hands of the respective holders
thereof valid and binding obligations of the Company, subject to applicable
bankruptcy and insolvency laws and the application of general principles of
equity.

        We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to us under the heading "Legal

admit that we are in the category of persons whose consent is required under
