                                   (Unaudited)

BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Article 10 of
Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation have
been included. Operating results for the three and six month periods ended June
30, 1999 are not necessarily indicative of the results that may be expected for
the year ended December 31, 1999. For further information, refer to the
consolidated financial statements and footnotes thereto included in Registrant's
annual report on Form 10-K for the year ended December 31, 1998.

REPURCHASE OF COMMON STOCK

During 1999, Registrant continued its program to repurchase a portion of its
outstanding stock, up to a maximum of 20 million shares. As of December 31,
1998, 6.4 million shares were repurchased under the current program. Through
June 30, 1999, an additional 8.4 million shares costing $244.6 million were
repurchased.

COMPREHENSIVE INCOME

Components of comprehensive income for Registrant are net earnings, foreign
currency translation adjustments and additional minimum pension liability
adjustments. For the second quarter of 1999 and 1998, total comprehensive
income, net of taxes, amounted to $127,351,000 and $111,745,000, respectively.
For the first six months of 1999 and 1998 total comprehensive income, net of
taxes, was $235,168,000 and $223,618,000, respectively.

DEBT ISSUANCE

On May 27, 1999, Registrant issued $240 million aggregate principal amount of
senior notes, of which $200 million is 7.25% fixed rate debt and $40 million is
floating rate debt, which bears interest at the three-month LIBOR plus 90 basis
points. The notes mature on June 1, 2009, with semiannual and quarterly interest
payments to be made on the fixed and floating rate notes, respectively. Costs
associated with the issuance of the notes have been capitalized, and are being
amortized over the term of the debt. Capitalized costs were not material.
Additionally, to hedge the interest rate risk on the $40 million floating rate
debt, Registrant executed an interest rate swap on May 27, 1999, effectively
fixing the rate at 7.25%.

ACCOUNTING PRONOUNCEMENTS

In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which provides new accounting rules for
various derivatives and related transactions. In June 1999, the FASB deferred
the effective date of SFAS No. 133 to fiscal quarters of fiscal years beginning
after June 15, 2000. Registrant is currently evaluating the timing of adoption
of SFAS No. 133. No material impact is expected upon adoption of this standard.

CONTINGENCIES

Registrant has been named in certain health care cost reimbursement/third party
recoupment/class action litigation against the major domestic cigarette
companies and others seeking damages and other relief. The complaints in these
cases on their face predominantly relate to the usage of cigarettes; within that
context, certain complaints contain a few allegations relating specifically to
smokeless tobacco products. These actions are in varying stages of pretrial
activities.

Registrant believes that these pending litigation matters will not result in any
material liability for a number of reasons, including the fact that Registrant
has had only limited involvement with cigarettes and Registrant's current
percentage of total tobacco industry sales is relatively small. Prior to 1986,
Registrant manufactured some cigarette products which had a de minimis market
share. From May 1, 1982 to August 1, 1994, Registrant distributed a small volume
of imported cigarettes and is indemnified against claims relating to those
products.

Registrant has been named in three actions brought by individual plaintiffs, all
of whom are represented by the same Louisiana attorney, against a number of
smokeless tobacco manufacturers, cigarette manufacturers and certain other
organizations seeking damages and other relief in connection with injuries
allegedly sustained as a result of tobacco usage, including smokeless tobacco
products.

Registrant is also named in an action in Illinois brought by an individual
plaintiff and purporting to state a class action "on behalf of himself and all
other persons similarly situated" alleging that Registrant "manipulates the
nicotine levels and absorption rates" in its smokeless tobacco products and
seeking to recover monetary damages "in an amount not less than the purchase
price" of Registrant's smokeless tobacco products and certain other relief.
The purported class excludes all persons who claim any personal injury as a
result of using Registrant's smokeless tobacco products.

Registrant is named in an action in North Carolina seeking unspecified damages
brought by an individual plaintiff who alleges that he developed bladder cancer
as a result of his usage of smokeless tobacco products manufactured by
Registrant.

Registrant is also named in several actions in West Virginia brought on behalf
of individual plaintiffs against cigarette manufacturers, smokeless tobacco
manufacturers, and other organizations seeking damages and other relief in
connection with injuries allegedly sustained as a result of tobacco usage,
including smokeless tobacco products. Included among the plaintiffs are two
individuals alleging, in addition to the use of other tobacco products, use of
Registrant's smokeless tobacco products and alleging the types of injuries
claimed to be associated with the use of smokeless tobacco products.

Registrant is also named in an action in San Francisco, California along with
five other smokeless tobacco manufacturers seeking damages and other relief
brought by the City and County of San Francisco and the Environmental Law
Foundation purportedly on behalf of "the residents of San Francisco County and
the general public" alleging violation of The Safe Drinking Water and Toxic
Enforcement Act of 1986, Health and Safety Code Sections 25249.6, et seq.
("Proposition 65") and the California Unfair Competition Act, Business and
Professions Code Sections 17200, et seq. The action alleges, among other things,
that the defendants sold smokeless tobacco products in California without
providing a ". . . `clear and reasonable' warning that their use results in
multiple exposures to substances known to the State of California to cause
cancer, birth defects and reproductive harm."

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Registrant is named in an action in Kentucky seeking more than $400 million in
"actual damages" before trebling, punitive damages and injunctive relief brought
by one of Registrant's competitors alleging that certain actions and practices
of Registrant violate federal antitrust and advertising laws in connection with
the marketing and sale of its moist snuff brands and also alleges various
violations of tort and state law.

Registrant believes, and has been so advised by counsel handling these cases,
that it has a number of meritorious defenses to all such pending litigation.
Except as to Registrant's willingness to consider alternative solutions for
resolving certain regulatory and litigation issues, all such cases are, and will
continue to be, vigorously defended. Registrant believes that the ultimate
outcome of all such pending litigation will not have a material adverse effect
on the consolidated financial position of Registrant, but may have a material
impact on Registrant's consolidated financial results for a particular reporting
period in which resolved.

On August 28, 1996, the Food and Drug Administration (FDA) published regulations
asserting unprecedented jurisdiction over nicotine in tobacco as a "drug" and
purporting to regulate smokeless tobacco products as a "medical device."
Registrant and other smokeless tobacco manufacturers filed suit against the FDA
seeking a judicial declaration that the FDA has no authority to regulate
smokeless tobacco products. On April 25, 1997, a federal district court ruled
that the FDA, as a matter of law, is not precluded from regulating cigarettes
and smokeless tobacco as "medical devices" and implementing certain labeling and
access restrictions. The court, granting Registrant's motion for summary
judgment, also ruled that the FDA has no authority to implement restrictions on
the advertising and promotion of smokeless tobacco products. The court issued an
injunction to prohibit most of the restrictions (labeling, access and
advertising/promotion) set for August 28, 1997 from taking effect, pending
resolution of any appeals and subsequent proceedings; the court also certified
the ruling for interlocutory appeal on the grounds that it involves "controlling
questions of law as to which there is substantial ground for difference of
opinion." On August 14, 1998, the Fourth Circuit Court of Appeals ruled in favor
of Registrant and other tobacco product manufacturers stating that the FDA lacks
jurisdiction to regulate tobacco products and that all of the regulations
published by the FDA on August 26, 1996 are invalid. On January 19, 1999, the
FDA filed a petition for certiorari seeking review of the Fourth Circuit's
ruling by the United States Supreme Court. On April 26, 1999, the United States
Supreme Court announced its intention to review that ruling; any decision is not
expected until 2000. Registrant is not able to predict the outcome of the
appeal, or assess the future effect that these FDA regulations, if implemented,
may have on its smokeless tobacco business.

                      OF OPERATIONS AND FINANCIAL CONDITION

Results of Operations
Second quarter and six months of 1999 compared
with the corresponding periods of 1998

CONSOLIDATED RESULTS

Consolidated net sales increased 6 percent to $378.1 million for the second
quarter of 1999, while net sales for the first six months of 1999 rose 4 percent
to $728.2 million. Net earnings for the second quarter increased 3 percent to
$123 million, compared to $119.1 million for the second quarter of 1998. Basic
and diluted earnings per share increased 9 percent to $.70 per share compared to
$.64 in the second quarter of 1998. For the first six months of 1999, net
earnings were $231.4 million and approximated net earnings for the same period
in 1998. Diluted earnings per share increased 5 percent and basic earnings per
share increased 4 percent to $1.30 per share in 1999.

Results for the second quarter of 1999 include tobacco settlement related
charges of $3 million, partially offset by a LIFO inventory benefit of $2.4
million, which is a result of the reorganization of the Registrant's tobacco
manufacturing subsidiary. Results for the first six months of 1999 include
tobacco settlement related charges of $6.1 million, partially offset by a LIFO
inventory benefit of $1.7 million. Included in results for the first six months
of 1998 was a $10.7 million gain on the sale of certain commercial agricultural
properties and the Registrant's video entertainment subsidiary, partially offset
by tobacco settlement related charges of $4.6 million and LIFO inventory expense
of $1.8 million. Excluding these items in the six-month periods, 1999 net
earnings and diluted earnings per share would have increased 3 percent and 7
percent, respectively, over the same period in the prior year.

The consolidated gross profit percentage increased slightly for both the second
quarter and the first six months of 1999, primarily due to higher selling prices
for moist smokeless tobacco products and relatively level costs of sales
compared with the prior year periods. Corporate expenses for the second quarter
of 1999 increased versus the second quarter of 1998, while corporate expenses
for the first six months of 1999 remained level with those of the corresponding
1998 period. Net interest expense increased to $3.2 million and $4.2 million for
the second quarter and first six months of 1999, respectively, primarily due to
higher average debt outstanding compared to the same periods in 1998.

TOBACCO SEGMENT

For the second quarter of 1999 Tobacco segment net sales increased 5.5 percent
to $334.7 million. Over the first six months of 1999, Tobacco segment net sales
increased 4.9 percent to $645.9 million accounting for 88.7 percent of
consolidated revenues. The increase in both periods was primarily attributable
to higher selling prices and a moderate unit volume increase for moist smokeless
tobacco products versus the similar 1998 periods. Net unit volume for moist
smokeless tobacco products increased 2.4 percent to 163.8 million cans and 1.6
percent to 313.3 million cans for the second quarter and first six months of
1999, respectively. Returned goods for both periods were significantly lower
than the corresponding 1998 periods due to improved management of promotional
activities.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
OPERATIONS AND FINANCIAL CONDITION (Continued)

Returned goods for the first six months of 1998 were adversely affected by the
initial implementation of the Registrant's program to enhance product freshness
at retail and several large promotions run in the latter part of the previous
year.

Cost of products sold decreased 5.5 percent for the second quarter and 4 percent
for the first six months of 1999 primarily as a result of lower unit costs for
moist smokeless tobacco products. The resulting lower unit costs include the
effects of the LIFO inventory benefits recorded in the second quarter and first
six months of 1999, respectively. Tobacco segment gross profit increased 7.4
percent for the second quarter and 6.4 percent for the first six months of 1999
as compared to the similar 1998 periods. The increases were primarily due to the
higher selling prices and the lower unit costs for moist smokeless tobacco.
Gross profit percentages for both periods increased slightly versus the prior
year periods as a result of these factors.

Selling and advertising expenses were stable for the second quarter and
increased in the six month period. The six month period included higher spending
on direct marketing initiatives and promotional activities. Indirect selling
expenses were higher in both 1999 periods primarily due to salaries and related
costs, attributable to additional sales and support personnel in the salesforce,
and increased spending on market research and sales training. Administrative
expenses also increased in both periods primarily as a result of tobacco
settlement related charges, higher salaries and related costs and legal fees.

Operating profit for the segment increased 7.3 percent to $206.9 million and 6.1
percent to $386.5 million for the second quarter and first six months of 1999,
respectively.

WINE SEGMENT

Wine segment net sales increased 9.6 percent to $36.2 million and 1.9 percent to
$68.3 million for the second quarter and first six months of 1999, respectively.
The net sales increase in both periods was primarily attributable to higher unit
volume for premium wines. Unit volume for the Registrant's two leading brands of
premium wine, Columbia Crest and Chateau Ste. Michelle (which accounted for more
than 78 percent of Wine segment unit sales in both 1999 periods), increased 13.2
percent and 6.5 percent for the second quarter and first six months of 1999,
respectively, over the corresponding periods in 1998.

Wine unit costs for both periods increased in 1999 due to the significantly
higher average grape costs associated with prior years' harvests used in
production. The increased unit costs caused a decrease in gross profit
percentage for the Wine segment for both 1999 periods.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
OPERATIONS AND FINANCIAL CONDITION (Continued)

Selling, advertising and administrative expenses were higher for both the second
quarter and the first six months of 1999 compared to the same periods in 1998.
Selling expenses increased slightly in both 1999 periods. Advertising expenses
were significantly higher for the first six months of 1999 primarily as a result
of media spending focused on the Registrant's premium varietal brands.
Administrative and other expenses increased in both 1999 periods, principally as
a result of higher salaries and related costs.

For the second quarter of 1999, operating profit for the Wine segment decreased
45.2 percent to $2.2 million, while for the first six months of 1999, segment
operating profit declined 54.8 percent to $4.3 million, as compared to the
corresponding 1998 periods.

ALL OTHER OPERATIONS

Net sales for all other operations for the second quarter of 1999 approximated
sales of the second quarter of 1998, while decreasing 4 percent for the first
six months of 1999 to $14 million. The decrease was primarily attributable to
lower unit volume in the Registrant's cigar operations, partially offset by
slightly higher revenues from the Registrant's international operations.
Overall, all other operations recorded operating losses of $2.5 million and $3.9
million for the second quarter and first six months of 1999, respectively,
compared to an operating loss of $2.6 million and operating profit of $5.4
million for the corresponding 1998 periods. Results for the first six months of
1998 include the effects of the $10.7 million pretax gain on the sale of certain
commercial agricultural properties and the Registrant's video entertainment
subsidiary which was reported as a reduction to administrative expenses.

LIQUIDITY AND SOURCES OF CAPITAL
CHANGES IN FINANCIAL CONDITION SINCE DECEMBER 31, 1998

Net cash provided by operating activities decreased compared to the
corresponding period in the prior year. The primary sources of cash from
operations were net earnings generated by the Tobacco segment and increased
income taxes payable. The primary uses of cash in operations were for raw
material inventories, mainly seasonal purchases of leaf tobacco for moist
smokeless tobacco products, and decreased accounts payable and accrued expenses.
Registrant anticipates that 1999 overall raw material purchases for leaf tobacco
and grapes will approximate amounts expended in 1998.

Net cash used in investing activities was $19.3 million in 1999, compared with
net cash provided by investing activities of $13.7 million in 1998. Both periods
included expenditures for purchases of property, plant and equipment. The net
cash provided by investing activities in 1998 included the Registrant's
disposition of its video entertainment subsidiary along with the sale of
property, plant and equipment, principally the sale of certain commercial
agricultural properties. The Registrant expects the 1999 capital program to
approximate $63 million.

UST Inc.
MANAGEMENT'S DISCUSSION AND ANALYSIS OF
OPERATIONS AND FINANCIAL CONDITION (Continued)

Net cash used in financing activities increased to $178.7 million in 1999,
compared to $140 million in 1998. The increase in 1999 is primarily due to cash
expended for the repurchase of common stock and the repayment of short-term
borrowings, partially offset by proceeds from additional borrowings. Included in
the proceeds from borrowings are the funds received upon issuance, in May 1999,
of $240 million in 10-year senior notes payable. The net proceeds from the
issuance of these notes were primarily used to repay other outstanding debt.
Included in 1998 is the effect of the Registrant's suspension of its stock
repurchase program. Funds allocated to the stock repurchase program for the
remainder of 1999 will approximate $145 million.

The Registrant will continue to have significant cash requirements for the
remainder of 1999, primarily for the repurchase of common stock, payment of
dividends and capital spending. These requirements are expected to be met by
internally generated funds supported by additional borrowings, when necessary.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Effective May 27, 1999, Registrant executed an interest rate swap contract with
a third party to effectively hedge the interest rate on the $40 million floating
rate 10-year senior notes payable issued on that date. The $200 million 10-year
senior notes payable are not subject to changes in market rates of interest as
these notes carry a fixed rate of interest.

YEAR 2000 ISSUE

Based on a risk assessment, Registrant has developed plans to address the year
2000 issue. Registrant's year 2000 plan includes both information technology
(IT) systems and non-IT systems and a risk assessment of its major vendors and
customers. Registrant's most critical business system was replaced with year
2000 compliant software in 1998 and all other identified critical business
systems were replaced or modified during the first half of 1999. Ongoing
remediation and testing of non-critical business IT systems and non-IT systems
will be completed in the fourth quarter of 1999.

In order to determine the state of readiness and potential effects on its
business, Registrant has surveyed its major vendors and customers. Registrant
has also completed several site visits of its most critical vendors and
customers. Based upon Registrant's inquiries and site visits, it has determined
that its major vendors and customers appear to have adequately addressed the
year 2000 issue. However, Registrant has no assurance that these vendors and
customers will be year 2000 ready.

Based on currently available information, Registrant estimates that the cost to
become year 2000 compliant will not be material.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
OPERATIONS AND FINANCIAL CONDITION (Continued)

Incomplete or untimely resolution of the year 2000 issue by Registrant or
critically important customers or vendors could cause delays in Registrant's
ability to manufacture and ship its products, process transactions or engage in
similar normal business activities, which would have a material financial impact
on Registrant's operations. With the implementation of its year 2000 plan,
Registrant believes the year 2000 issue should not pose any significant
operational problems.

Registrant has developed contingency plans and will evaluate the need for
modifications as additional information becomes available. Registrant's
contingency plans include pre-arranged shipments to customers and stockpiling or
securing alternate sources of manufacturing supplies in order to minimize the
potential disruption of business operations that may result if its vendors or
customers fail to become year 2000 compliant.

FORWARD-LOOKING AND CAUTIONARY STATEMENTS

Reference is made to the section captioned "Cautionary Statement Regarding
Forward-Looking Information" which was filed as part of Item 7 - Management's
Discussion and Analysis of Financial Condition and Results of Operations of
Registrant's 1998 Form 10-K, and to the report on execution of the Smokeless
Tobacco Master Settlement Agreement on Form 8-K, dated November 25, 1998, and
first quarter Form 10-Q, regarding important factors that could cause actual
results to differ materially from those contained in any forward-looking
statement made by Registrant, including forward-looking statements contained in
this report.

Item 1.           Legal Proceedings

                  On May 18, 1999, Registrant was served with an Amended
                  Complaint in an action entitled Arthur D. Brown v. Philip
                  Morris Incorporated, et al. (No. 98-C-02344), Circuit Court of
                  Kanawha County, West Virginia. This action is brought by an
                  individual plaintiff against three cigarette manufacturers,
                  one cigar manufacturer and two smokeless tobacco
                  manufacturers, including Registrant, for laryngeal cancer and
                  other injuries allegedly sustained as a result of his use of
                  various tobacco products, including one of Registrant's
                  smokeless tobacco products. The Amended Complaint seeks
                  unspecified compensatory and punitive damages and other
                  relief. Registrant intends to defend this action vigorously.

                  Complaint in an action entitled Edith June Graham and William
                  Leroy Graham, her husband v. Philip Morris Incorporated, et
                  al. (No. 98-C-02366), Circuit Court of Kanawha County, West
                  Virginia. This action was brought by an individual plaintiff
                  and her spouse against four cigarette manufacturers and
                  Registrant for mouth cancer and other injuries allegedly
                  sustained as a result of her cigarette smoking and use of one
                  of Registrant's smokeless tobacco products. The Amended
                  Complaint seeks unspecified compensatory and punitive damages
                  and other relief. Registrant intends to defend this action
                  vigorously.

given, made or taken by Holders of Securities of such series, provided that the

Securities of the relevant series on such record date,



                                      -11-

action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be cancelled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Securities of the relevant
series on the date such action is taken. Promptly after any record date is set
pursuant to this paragraph, the Company, at its own expense, shall cause notice
of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Trustee in writing and to each Holder of
Securities of the relevant series in the manner set forth in Section 106.

acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2) or (iv) any direction referred to in
Section 512, in each case with respect to Securities of such series. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date; provided that no such
action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date. Nothing in this paragraph shall
be construed to prevent the Trustee from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be canceled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Securities of the relevant
series on the date such action is taken. Promptly after any record date is set
pursuant to this paragraph, the Trustee, at the Company's expense, shall cause
notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Company in writing and to each Holder of
Securities of the relevant series in the manner set forth in Section 106.

      With respect to any record date set pursuant to this Section, the party
hereto which sets such record dates may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day; provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of Securities of the relevant series in the manner set forth in
Section 106, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto which set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the



                                      -12-


<PAGE>   22
Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no
Expiration Date shall be later than the 180th day after the applicable record
date.

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

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

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

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

                  (2) the Company by the Trustee or by any Holder shall be
         sufficient for every purpose hereunder (unless otherwise herein
         expressly provided) if in writing and mailed, first-class postage
         prepaid, to the Company addressed to it 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 106. Notice to Holders; Waiver.

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

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

SECTION 107. Conflict with Trust Indenture Act.

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

SECTION 108. Effect of Headings and Table of Contents.

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


SECTION 109. 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 110. Separability Clause.

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


SECTION 111. Benefits of Indenture.

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


SECTION 112. Governing Law.

accordance with the law of the State of New York.

SECTION 113. Legal Holidays.

      In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the Securities
(other than a provision of any Security which specifically states that such
provision shall apply in lieu of this Section)) payment of interest or principal
(and premium, if any) need not be made at such Place of Payment on such date,
but may be made on the next succeeding Business Day at such Place of Payment
with the same force and effect as if made on the Interest Payment Date or
Redemption Date, or at the Stated Maturity.

                                 SECURITY FORMS


SECTION 201. Forms Generally.

      The Securities of each series shall be in substantially the form set forth
in this Article, or in such other form as shall be established by or pursuant to
a Board Resolution or in one or more indentures supplemental hereto, in each
case with such appropriate insertions, omissions, substitutions and other
variations as are required or permitted by this Indenture, and may have such
letters, numbers or other marks of identification and such legends or
endorsements placed thereon as may be required to comply with the rules of any
securities exchange or Depositary therefor or as may, consistently herewith, be
determined by the officers executing such Securities, as evidenced by their
execution thereof. If the form of Securities of any series is established by
action taken pursuant to a Board Resolution, a copy of an appropriate record of
such action shall be certified by the Secretary or an Assistant Secretary of the
Company and delivered to the Trustee at or prior to the delivery of the Company
Order contemplated by Section 303 for the authentication and delivery of such
Securities.

      The definitive Securities shall be printed, lithographed or engraved on
steel engraved borders or may be produced in any other manner, all as determined

Depositary, or its nominee [and deposited with the Trustee, as custodian for
DTC,] for credit by DTC to the respective accounts of beneficial owners of the
Securities represented thereby (or such other accounts as they may direct). Such
Global Securities, together with their Successor Securities which are Global
Securities other than the Regulation S Global Security, are collectively herein
called the "Restricted Global Security".

payment. [If applicable then insert: provided that any principal and premium,
and any such instalment of interest, which is overdue shall bear interest at the
rate of ...% per annum (to the extent that the payment of such interest shall be
legally enforceable), from the dates such amounts are due until they are paid or
made available for payment, and such interest shall be payable on demand.] [If
Original Securities that are not also Registered Securities, then insert:
provided, however, that if (i) the Company has not filed a registration
statement (the "Exchange Registration Statement") under the Securities Act of
1933, as amended (the "Securities Act"), registering a security substantially
identical to this Security (except that such Security will not contain terms
with respect to the Special Interest payments described below or transfer
restrictions) pursuant to an exchange offer (the "Exchange Offer") within

obligation arises pursuant to the Indenture, a registration statement
registering this Security for resale (a "Resale Registration Statement") within
30 days of such after the time such obligation arises)), or (ii) the Exchange
Registration Statement relating to the Exchange Offer has not become or been
declared effective within 180 days of filing (or, if applicable, the Resale
Registration Statement has not become or been declared effective within 120 days
after such Resale Registration Statement has become or been declared effective),

to the Exchange and Registration Rights Agreement (the "Exchange and
Registration Rights Agreement"), dated as of May 27, 1999, by and between the
Company, the Purchasers (as defined therein) and the Holders from time to time
of the Securities) or (iv) either the Exchange Registration Statement or, if
applicable, the Resale Registration Statement is filed and declared effective
(except as specifically permitted therein) but shall thereafter cease to be
effective without being succeeded promptly by an additional registration
statement filed and declared effective, in each case (i) through (iv) upon the
terms and conditions set forth in the Exchange and Registration Rights Agreement
(each such event referred to in clauses (i) through (iv), a "Registration
Default"), then special interest ("Special Interest") will accrue (in addition
to the stated interest on the Securities) at a per annum rate of 0.25% for the
first 90 days, determined daily, on the principal amount of the Securities, from
the period from the occurrence of the Registration Default until such time as no
Registration Default is in effect and, provided, further, that if either the
Exchange Offer has not been consummated or, if applicable, the Resale
Registration Statement has not become or been declared effective, in each case
within this first 90 days, then the per annum rate of such Special Interest
shall increase by an additional 0.25% per annum for each subsequent 90-day
period (provided that the rate of Special Interest shall not exceed 1.0% per
annum in the aggregate) and Special Interest will be payable at such increased
rate until such time as the Company consummates the Exchange Offer or, if
applicable, the Resale Registration Statement becomes or has been declared
effective (after which such interest rate will be restored to its initial rate).
Interest accruing as a result of Registration Default (which shall be computed
on the basis of a 365-day year) is referred to herein as "Special Interest."
Accrued Special Interest, if any, shall be paid semi-annually on ____ and
______, in each year; and the amount of accrued Special Interest shall be
determined on the basis of the number of days actually elapsed. Any accrued and
unpaid interest (including Special Interest) on this Security upon the issuance
of an Exchange Security (as defined in the Indenture) in exchange for this
Security shall cease to be payable to the Holder hereof but such accrued and
unpaid interest (including Special Interest) shall be payable on the next
Interest Payment Date for such Exchange Security to the Holder thereof on the
related Regular Record Date.]

      The interest so payable, and punctually paid or duly provided for, on any
Interest Payment Date will, as provided in such Indenture, be paid to the Person
in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such
interest, which shall be the ....... or ....... (whether or not a Business Day),
as the case may be, next preceding such Interest Payment Date. Any such interest
not so punctually paid or duly provided for will forthwith cease to be payable

name this Security (or one or more Predecessor Securities) is registered at the
close of business on a Special Record Date for the payment of such Defaulted
Interest to be fixed by the Trustee, notice whereof shall be given to Holders of
Securities of this series not less than 10 days prior to such Special Record
Date, or be paid at any time in any other lawful manner not inconsistent with
the requirements of any securities exchange on which the Securities of this
series may be listed, and upon such notice as may be required by such exchange,
all as more fully provided in said Indenture.

[If the Security is not to bear interest prior to Maturity, insert -- The
principal of this Security shall not bear interest except in the case of a
default in payment of principal upon acceleration, upon redemption or at Stated
Maturity and in such case the overdue principal and any overdue premium shall
bear interest at the rate of ....% per annum (to the extent that the payment of
such interest shall be legally enforceable), from the dates such amounts are due
until they are paid or made available for payment. Interest on any overdue
principal or premium shall be payable on demand. [Any such interest on overdue
principal or premium which is not paid on demand shall bear interest at the rate
of ....% per annum (to the extent that the payment of such interest on interest
shall be legally enforceable), from the date of such demand until the amount so
demanded is paid or made available for payment. Interest on any overdue interest
shall be payable on demand.]]

agency of the Company maintained for that purpose in ............, in such coin
or currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts [if applicable, insert --;
provided, however, that at the option of the Company payment of interest may be
made by check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register].

forth on the reverse hereof, which further provisions shall for all purposes

provisions permitting the Holders of specified percentages in principal amount

Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee

Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60
days after receipt of such notice, request and offer of indemnity. The foregoing
shall not apply to any suit instituted by the Holder of this Security for the
enforcement of any payment of principal hereof or any premium or interest hereon
on or after the respective due dates expressed herein.

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

      As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in any place where the principal of and any
premium and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Securities of

SECTION 302. Denominations.

      The Securities of each series shall be issuable only in registered form
without coupons and only in such denominations as shall be specified as
contemplated by Section 301. In the absence of any such specified denomination

shall be issuable in denominations of $1,000 and any integral multiple thereof.


SECTION 303. Execution, Authentication, Delivery and Dating.

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

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

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

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

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

       (3) that such Securities, when authenticated and delivered by the Trustee
   and issued by the Company in the manner and subject to any conditions
   specified in such Opinion of Counsel, will constitute valid and legally
   binding obligations of the Company enforceable in accordance with their
   terms, subject to bankruptcy, insolvency, fraudulent



                                      -28-
<PAGE>   38
      transfer, reorganization, moratorium and similar laws of general
      applicability relating to or affecting creditors' rights and to general
      equity principles.

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

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

      Each Security shall be dated the date of its authentication.

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


SECTION 304. Temporary Securities.

      Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities.

      If temporary Securities of any series are issued, the Company will cause
definitive Securities of that series to be prepared without unreasonable delay.
After the preparation of definitive Securities of such series, the temporary
Securities of such series shall be exchangeable for definitive Securities of
such series upon surrender of the temporary Securities of such series at the
office or agency of the Company in a Place of Payment for that series, without
charge to the Holder. Upon surrender for cancellation of any one or more



                                      -29-
<PAGE>   39
temporary Securities of any series, the Company shall execute and the Trustee
shall authenticate and deliver in exchange therefor one or more definitive
Securities of the same series, of any authorized denominations and of like tenor
and aggregate principal amount. 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 and tenor.


SECTION 305. Registration, Registration of Transfer and Exchange; Certain
             Transfers and Exchanges

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

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

      Subject to Section 306(b), at the option of the Holder, Securities of any
series may be exchanged for other Securities of the same series, of any
authorized denominations and of like tenor and aggregate principal amount, upon
surrender of the Securities to be exchanged at such office or agency. Whenever
any Securities are so surrendered for exchange, the Company shall execute, and
the Trustee shall authenticate and deliver, the Securities which the Holder
making the exchange is entitled to receive.

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

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

      No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of



                                      -30-
<PAGE>   40
transfer or exchange of Securities, other than exchanges pursuant to Section
304, 906 or 1107 not involving any transfer.

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

      The provisions of Clauses (1), (2), (3) and (4) below shall apply only to
Global Securities:

       (1) Each Global Security authenticated under this Indenture shall be
   registered in the name of the Depositary designated for such Global Security
   or a nominee thereof and delivered to such Depositary or a nominee thereof or
   custodian therefor, and each such Global Security shall constitute a single
   Security for all purposes of this Indenture.

       (2) Notwithstanding any other provision in this Indenture, no Global
   Security may be exchanged in whole or in part for Securities registered, and
   no transfer of a Global Security in whole or in part may be registered, in
   the name of any Person other than the Depositary for such Global Security or
   a nominee thereof unless (A) such Depositary (i) has notified the Company
   that it is unwilling or unable to continue as Depositary for such Global
   Security or (ii) has ceased to be a clearing agency registered under the
   Exchange Act, (B) there shall have occurred and be continuing an Event of
   Default with respect to such Global Security or (C) there shall exist such
   circumstances, if any, in addition to or in lieu of the foregoing as have
   been specified for this purpose as contemplated by Section 301.

       (3) Subject to Clause (2) above, any exchange of a Global Security for
   other Securities may be made in whole or in part, and all Securities issued
   in exchange for a Global Security or any portion thereof shall be registered
   in such names as the Depositary for such Global Security shall direct.

       (4) Every Security authenticated and delivered upon registration of
   transfer of, or in exchange for or in lieu of, a Global Security or any
   portion thereof, whether pursuant to this Section, Section 304, 306, 906 or
   1107 or otherwise, shall be authenticated and delivered in the form of, and
   shall be, a Global Security, unless such Security is registered in the name
   of a Person other than the Depositary for such Global Security or a nominee
   thereof.

      (b) Certain Transfers and Exchanges. Notwithstanding any other provision
of this Indenture or the Securities, transfers and exchanges of Securities and
beneficial interests in



                                      -31-
<PAGE>   41
a Global Security of the kinds specified in this Section 305(b) shall be made
only in accordance with this Section 305(b).

       (i) Restricted Global Security to Regulation S Global Security. If the
   owner of a beneficial interest in the Restricted Global Security wishes at
   any time to transfer such interest to a Person who wishes to acquire the same
   in the form of a beneficial interest in the Regulation S Global Security,
   such transfer may be effected only in accordance with the provisions of this
   Clause (b)(i) and Clause (b)(iv) below and subject to the Applicable
   Procedures. Upon receipt by the Trustee, as Security Registrar, of (A) an
   order given by the Depositary or its authorized representative directing that
   a beneficial interest in the Regulation S Global Security in a specified
   principal amount be credited to a specified Agent Member's account and that a
   beneficial interest in the Restricted Global Security in an equal principal
   amount be debited from another specified Agent Member's account and (B) a
   Regulation S Certificate, satisfactory to the Trustee and duly executed by
   the owner of such beneficial interest in the Restricted Global Security or
   his attorney duly authorized in writing, then the Trustee, as Security
   Registrar but subject to Clause (b)(iv) below, shall reduce the principal
   amount of the Restricted Global Security and increase the principal amount of
   the Regulation S Global Security by such specified principal amount.

      (ii) Regulation S Global Security to Restricted Global Security. If the
   owner of a beneficial interest in the Regulation S Global Security wishes at
   any time to transfer such interest to a Person who wishes to acquire the same
   in the form of a beneficial interest in the Restricted Global Security, such
   transfer may be effected only in accordance with this Clause (b)(ii) and
   subject to the Applicable Procedures. Upon receipt by the Trustee, as
   Security Registrar, of (A) an order given by the Depositary or its authorized
   representative directing that a beneficial interest in the Restricted Global
   Security in a specified principal amount be credited to a specified Agent
   Member's account and that a beneficial interest in the Regulation S Global
   Security in an equal principal amount be debited from another specified Agent
   Member's account and (B) if such transfer is to occur during the Restricted
   Period, a Restricted Securities Certificate, satisfactory to the Trustee and
   duly executed by the owner of such beneficial interest in the Regulation S
   Global Security or his attorney duly authorized in writing, then the Trustee,
   as Security Registrar, shall reduce the principal amount of the Regulation S
   Global Security and increase the principal amount of the Restricted Global
   Security by such specified principal amount. If transfers under this Clause
   (b)(ii) occur after the Restricted Period, no Restricted Securities
   Certificates will be required.

      (iii) Non-Global Security to Non-Global Security. A Security that is not a
   Global Security may be transferred, in whole or in part, to a Person who
   takes delivery in the form of another Security that is not a Global Security
   as provided in Section 305(a), provided that, if the Security to be
   transferred in whole or in part is a Restricted Security, then the Trustee
   shall have received a Restricted Securities Certificate, satisfactory to the
   Trustee and duly executed by the transferor Holder or his attorney duly
   authorized in writing, in which case the transferee Holder shall take
   delivery in the form of a Restricted Security (subject in every case to
   Section 305(c)).


                                      -32-
<PAGE>   42
      (iv) Regulation S Global Security to be Held Through Euroclear or Cedel
    during Restricted Period. The Company shall use its best efforts to cause
    the Depositary to ensure that beneficial interests in the Regulation S
    Global Security may be held only in or through accounts maintained at the
    Depositary by Euroclear or Cedel (or by Agent Members acting for the account
    thereof), and no person shall be entitled to effect any transfer or exchange
    that would result in any such interest being held otherwise than in or
    through such an account; provided that this Clause (b)(iv) shall not
    prohibit any transfer or exchange of such an interest in accordance with
    Clause (b)(ii) above.

      (v) Restricted Non-Global Security to Restricted Global Security or
    Regulation S Global Security. If the Holder of a Restricted Security (other
    than a Global Security) wishes at any time to transfer all or any portion of
    such Security to a Person who wishes to take delivery thereof in the form of
    a beneficial interest in the Restricted Global Security or the Regulation S
    Global Security, such transfer may be effected only in accordance with the
    provisions of this Clause (b)(vi) and Clause (b)(iv) above and subject to
    the Applicable Procedures. Upon receipt by the Trustee, as Security
    Registrar, of (A) such Security as provided in Section 305(a) and
    instructions satisfactory to the Trustee directing that a beneficial
    interest in the Restricted Global Security or Regulation S Global Security
    in a specified principal amount not greater than the principal amount of
    such Security be credited to a specified Agent Member's account and (B) a
    Restricted Securities Certificate, if the specified account is to be
    credited with a beneficial interest in the Restricted Global Security, or a
    Regulation S Certificate, if the specified account is to be credited with a
    beneficial interest in the Regulation S Global Security, in either case
    satisfactory to the Trustee and duly executed by such Holder or his attorney
    duly authorized in writing, then the Trustee, as Security Registrar but
    subject to Clause (b)(iv) below, shall cancel such Security (and issue a new
    Security in respect of any untransferred portion thereof) and increase the
    principal amount of the Restricted Global Security or the Regulation S
    Global Security, as the case may be, by the specified principal amount, both
    as provided in Section 305(a).

      (c) Securities Act Legends. Restricted Securities and their Successor
Securities shall bear a Restricted Securities Legend, and the Regulation S
Securities and their Successor Securities shall bear a Regulation S Legend,
subject to the following:

      (i) subject to the following Clauses of this Section 305(c), a Security or
    any portion thereof which is exchanged, upon transfer or otherwise, for a
    Global Security or any portion thereof shall bear the Securities Act Legend
    borne by such Global Security while represented thereby;

      (ii) subject to the following Clauses of this Section 305(c), a new
    Security which is not a Global Security and is issued in exchange for
    another Security (including a Global Security) or any portion thereof, upon
    transfer or otherwise, shall bear the Securities Act Legend borne by such
    other Security, provided that, if such new Security is required pursuant to
    Section 305(b)(v) to be issued in the form of a Restricted Security, it
    shall bear a Restricted Securities Legend and, if such new Security is so
    required to be issued in the form of a Regulation S Security, it shall bear
    a Regulation S Legend;



                                      -33-
<PAGE>   43
      (iii) Registered Securities shall not bear a Securities Act Legend;

      (iv) at any time after the Securities may be freely transferred without
   registration under the Securities Act or without being subject to transfer
   restrictions pursuant to the Securities Act, a new Security which does not
   bear a Securities Act Legend may be issued in exchange for or in lieu of a
   Security (other than a Global Security) or any portion thereof which bears
   such a legend if the Trustee has received an Unrestricted Securities
   Certificate, satisfactory to the Trustee and duly executed by the Holder of
   such legended Security or his attorney duly authorized in writing, and after
   such date and receipt of such certificate, the Trustee shall authenticate and
   deliver such a new Security in exchange for or in lieu of such other Security
   as provided in this Article Three;

       (v) a new Security which does not bear a Securities Act Legend may be
   issued in exchange for or in lieu of a Security (other than a Global
   Security) or any portion thereof which bears such a legend if, in the
   Company's judgment, placing such a legend upon such new Security is not
   necessary to ensure compliance with the registration requirements of the
   Securities Act, and the Trustee, at the direction of the Company, shall
   authenticate and deliver such a new Security as provided in this Article
   Three; and

      (vi) notwithstanding the foregoing provisions of this Section 305(c), a
   Successor Security of a Security that does not bear a particular form of
   Securities Act Legend shall not bear such form of legend unless the Company
   has reasonable cause to believe that such Successor Security is a "restricted
   security" within the meaning of Rule 144, in which case the Trustee, at the
   direction of the Company, shall authenticate and deliver a new Security
   bearing a Restricted Securities Legend in exchange for such Successor
   Security as provided in this Article Three.

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

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

      If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be required by them to save each of them and
any agent of either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Security, a new Security
of the same series and of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

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





                                      -34-
<PAGE>   44
      Upon the issuance of any new Security under this Section, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.

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

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


SECTION 307. Payment of Interest; Interest Rights Preserved.

      Except as otherwise provided as contemplated by Section 301 with respect
to any series of Securities, interest on any Security which is payable, and is
punctually paid or duly provided for, on any Interest Payment Date shall be paid
to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.

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

         (1) The Company may elect to make payment of any Defaulted Interest to
      the Persons in whose names the Securities of such series (or their
      respective Predecessor Securities) are registered at the close of business
      on a Special Record Date for the payment of such Defaulted Interest, which
      shall be fixed in the following manner. The Company shall notify the
      Trustee in writing of the amount of Defaulted Interest proposed to be paid
      on each Security of such series and the date of the proposed payment, and
      at the same time the Company shall deposit with the Trustee an amount of
      money equal to the aggregate amount proposed to be paid in respect of such
      Defaulted Interest or shall make arrangements satisfactory to the Trustee
      for such deposit prior to the date of the proposed payment, such money
      when deposited to be held in trust for the benefit of the Persons entitled
      to such Defaulted Interest as in this Clause provided. Thereupon the
      Trustee shall fix a Special Record Date for the payment of such Defaulted
      Interest which shall be not more than 15 days and not less than 10 days
      prior to the date of the proposed payment and not less than 10 days after
      the receipt by the Trustee of the notice of the proposed payment. The
      Trustee shall promptly notify the Company of such Special Record Date and,
      in the name and at the



                                      -35-
<PAGE>   45
      expense of the Company, shall cause notice of the proposed payment of such
      Defaulted Interest and the Special Record Date therefor to be given to
      each Holder of Securities of such series in the manner set forth in
      Section 106, not less than 10 days prior to such Special Record Date.
      Notice of the proposed payment of such Defaulted Interest and the Special
      Record Date therefor having been so mailed, such Defaulted Interest shall
      be paid to the Persons in whose names the Securities of such series (or
      their respective Predecessor Securities) are registered at the close of
      business on such Special Record Date and shall no longer be payable
      pursuant to the following Clause (2).

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

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


SECTION 308. Persons Deemed Owners.

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


SECTION 309. Cancellation.

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



                                      -36-
<PAGE>   46
Indenture. All cancelled Securities held by the Trustee shall be disposed of as
directed by a Company Order.

SECTION 310. Computation of Interest.

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

                           SATISFACTION AND DISCHARGE


SECTION 401. Satisfaction and Discharge of Indenture.

      This Indenture shall upon Company Request cease to be of further effect
(except as to any surviving rights of registration of transfer or exchange of
Securities herein expressly provided for), and the Trustee, at the expense of
the Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

      (1)   either

         (A) all Securities theretofore authenticated and delivered (other than
      (i) Securities which have been destroyed, lost or stolen and which have
      been replaced or paid as provided in Section 306 and (ii) Securities for
      whose payment money has theretofore been deposited in trust or segregated
      and held in trust by the Company and thereafter repaid to the Company or
      discharged from such trust, as provided in Section 1003) have been
      delivered to the Trustee for cancellation; or

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

             (i)  have become due and payable, or

             (ii) will become due and payable at their Stated Maturity within
           one year, or

             (iii) are to be called for redemption within one year under
           arrangements satisfactory to the Trustee for the giving of notice of
           redemption by the Trustee in the name, and at the expense, of the
           Company,

      and the Company, in the case of (i), (ii) or (iii) above, has deposited or
      caused to be deposited with the Trustee as trust funds in trust for the
      purpose money in an amount sufficient to pay and discharge the entire
      indebtedness on such Securities not theretofore delivered to the Trustee
      for cancellation, for principal and any premium and



                                      -37-
<PAGE>   47
      interest to the date of such deposit (in the case of Securities which have
      become due and payable) or to the Stated Maturity or Redemption Date, as
      the case may be;

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

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

      Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of
the Trustee to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of
this Section, the obligations of the Trustee under Section 402 and the last
paragraph of Section 1003 shall survive.


SECTION 402. Application of Trust Money.

      Subject to the provisions of the last paragraph of Section 1003, all money
deposited with the Trustee pursuant to Section 401 shall be held in trust and
applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money has been deposited with the Trustee.

                                    REMEDIES


SECTION 501. Events of Default.

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

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

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



                                      -38-
<PAGE>   48
            (3) default in the deposit of any sinking fund payment, when and as
      due by the terms of a Security of that series; or

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

            (5) a default under any bond, debenture, note or other evidence of
      indebtedness for money borrowed by the Company (including a default with
      respect to Securities of any series other than that series) having an
      aggregate principal amount outstanding of at least $10,000,000, or under
      any mortgage, indenture or instrument (including this Indenture) under
      which there may be issued or by which there may be secured or evidenced
      any indebtedness for money borrowed by the Company having an aggregate
      principal amount outstanding of at least $10,000,000, whether such
      indebtedness now exists or shall hereafter be created, which default

      shall have resulted in such indebtedness becoming or being declared due
      and payable prior to the date on which it would otherwise have become due
      and payable, without such acceleration having been rescinded or annulled,
      within a period of 10 days after there shall have been given, by
      registered or certified mail, to the Company by the Trustee or to the
      Company and the Trustee by the Holders of at least 10% in principal amount
      of the Outstanding Securities of that series a written notice specifying
      such default and requiring the Company to cause such indebtedness to be
      discharged or cause such acceleration to be rescinded or annulled, as the
      case may be, and stating that such notice is a "Notice of Default"
      hereunder; provided, however, that, subject to the provisions of Sections
      601 and 602, the Trustee shall not be deemed to have knowledge of such
      default unless either (A) a Responsible Officer of the Trustee shall have
      actual knowledge of such default or (B) the Trustee shall have received
      written notice thereof from the Company, from any Holder, from the holder
      of any such indebtedness or from the trustee under any such mortgage,
      indenture or other instrument; or

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



                                      -39-
<PAGE>   49
      liquidation of its affairs, and the continuance of any such decree or
      order for relief or any such other decree or order unstayed and in effect
      for a period of 60 consecutive days; or

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

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


SECTION 502. Acceleration of Maturity; Rescission and Annulment.

      If an Event of Default (other than an Event of Default specified in
Section 501(6) or 501(7)) with respect to Securities of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of that series may declare the principal amount of all the Securities of that
series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be
specified by the terms thereof) to be due and payable immediately, by a notice
in writing to the Company (and to the Trustee if given by Holders), and upon any
such declaration such principal amount (or specified amount) shall become
immediately due and payable. If an Event of Default specified in Section 501(6)
or 501 (7) with respect to Securities of any series at the time Outstanding
occurs, the principal amount of all the Securities of that series (or, if any
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount of such Securities as may be specified by the terms
thereof) shall automatically, and without any declaration or other action on the
part of the Trustee or any Holder, become immediately due and payable.

      At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a major-



                                      -40-
<PAGE>   50
ity in principal amount of the Outstanding Securities of that series, by written
notice to the Company and the Trustee, may rescind and annul such declaration
and its consequences if

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

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

         (B) the principal of (and premium, if any, on) any Securities of that
      series which have become due otherwise than by such declaration of
      acceleration and any interest thereon at the rate or rates prescribed
      therefor in such Securities,

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

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

   and

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

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


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

      The Company covenants that if

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

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

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



                                      -41-
<PAGE>   51
      If an Event of Default with respect to Securities of any series occurs and
is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series by such
appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any such rights, whether for the specific enforcement of any
covenant or agreement in this Indenture or in aid of the exercise of any power
granted herein, or to enforce any other proper remedy.

SECTION 504.   Trustee May File Proofs of Claim.

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

      No provision of this Indenture shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.


SECTION 505.   Trustee May Enforce Claims without Possession of Securities.

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


                                      -42-

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

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

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

   indemnity against the costs, expenses and liabilities to be incurred in
   compliance with such request;

      (4) the Trustee for 60 days after its receipt of such notice, request and

any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such

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

SECTION 509.   Restoration of Rights and Remedies.

      If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or
to such Holder, then and in every such case, subject to any determination in
such proceeding, the Company, the Trustee and the Holders shall be restored
severally and respectively to their former positions hereunder and thereafter
all rights and remedies of the Trustee and the Holders shall continue as though
no such proceeding had been instituted.

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


SECTION 511.   Delay or Omission Not Waiver.

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

SECTION 512.   Control by Holders.

      The Holders of a majority in principal amount of the Outstanding
Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee, with respect to the
Securities of such series, provided that

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

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

SECTION 513.   Waiver of Past Defaults.

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

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

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

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


SECTION 514.   Undertaking for Costs.

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

SECTION 515.   Waiver of Usury, Stay or Extension Laws.

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


                                   ARTICLE SIX

SECTION 601.   Certain Duties and Responsibilities.

      The duties and responsibilities of the Trustee shall be as provided by the
Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it. Whether or not therein
expressly so provided, every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.


SECTION 602.   Notice of Defaults.

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

SECTION 603.   Certain Rights of Trustee.

      Subject to the provisions of Section 601:

      (1) the Trustee may rely and shall be protected in acting or refraining
   from acting upon any resolution, certificate, statement, instrument, opinion,

   other evidence of indebtedness or other paper or document believed by it to

   deem it desirable that a matter be proved or established prior to taking,

   evidence be herein specifically prescribed) may, in the absence of bad faith
   on its part, rely upon an Officers' Certificate;

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

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

      (6) the Trustee shall not be bound to make any investigation into the
   facts or matters stated in any resolution, certificate, statement,
   instrument, opinion, report, notice, request, direction, consent, order,
   bond, debenture, note, other evidence of indebtedness or other paper or
   document, but the Trustee, in its discretion, may make such further inquiry
   or investigation into such facts or matters as it may see fit, and, if the
   Trustee shall determine to make such further inquiry or investigation, it
   shall be entitled to examine the books, records and premises of the Company,
   personally or by agent or attorney; and

      (7) the Trustee may execute any of the trusts or powers hereunder or
   perform any duties hereunder either directly or by or through agents or

   hereunder.

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

      The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and neither the Trustee nor any Authenticating Agent assumes any responsibility
for their correctness. The Trustee makes no representations as to the validity
or sufficiency of this Indenture or of the Securities. Neither the Trustee nor
any Authenticating Agent shall be accountable for the use or application by the
Company of Securities or the proceeds thereof.


SECTION 605.   May Hold Securities.

      The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
608 and 613, may otherwise deal with the Company with the same rights it would
have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

SECTION 606.   Money Held in Trust.

      Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed with the Company.


SECTION 607.   Compensation and Reimbursement.

      The Company agrees

      (1) to pay to the Trustee from time to time reasonable compensation for
   all services rendered by it 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 (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 its negligence or bad
   faith; and

      (3) to indemnify the Trustee for, and to hold it harmless against, any
   loss, liability or expense incurred without negligence or bad faith on its
   part, arising out of or in connection with the acceptance or administration
   of the trust or trusts hereunder, including the costs and expenses of
   defending itself against any claim or liability in connection with the
   exercise or performance of any of its powers or duties hereunder.

SECTION 608.   Conflicting Interests.

      If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture. To the extent
permitted by such Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under this Indenture with respect to
Securities of more than one series.


SECTION 609.   Corporate Trustee Required; Eligibility.

      There shall at all times be one (and only one) Trustee hereunder with
respect to the Securities of each series, which may be Trustee hereunder for
Securities of one or more other series. Each Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such and has a combined
capital and surplus of at least $50,000,000. If any such Person publishes
reports of condition at least annually, pursuant to law or to the requirements
of its supervising or examining authority, then for the purposes of this Section
and to the extent permitted by the Trust Indenture Act, the combined capital and
surplus of such Person shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time
the Trustee with respect to the Securities of any series shall cease to be
eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.


SECTION 610.   Resignation and Removal; Appointment of Successor.

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

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

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


                                      -49-
<PAGE>   59
      If at any time:

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

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

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

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

      If the Trustee shall resign, be removed or become incapable of acting, or
if a vacancy shall occur in the office of Trustee for any cause, with respect to
the Securities of one or more series, the Company, by a Board Resolution, shall
promptly appoint a successor Trustee or Trustees with respect to the Securities
of that or those series (it being understood that any such successor Trustee may
be appointed with respect to the Securities of one or more or all of such series
and that at any time there shall be only one Trustee with respect to the
Securities of any particular series) and shall comply with the applicable
requirements of Section 611. If, within one year after such resignation, removal
or incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment in accordance
with the applicable requirements of Section 611, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Company or
the Holders and accepted appointment in the manner required by Section 611, any
Holder who has been a bona fide Holder of a Security of such series for at least
six months may, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the appointment of a successor Trustee
with respect to the Securities of such series.

      The Company shall give notice of each resignation and each removal of the
Trustee with respect to the Securities of any series and each appointment of a
successor Trustee with respect to the Securities of any series to all Holders of
Securities of such series in the manner provided in Section 106. Each notice
shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.

SECTION 611.   Acceptance of Appointment by Successor.

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

      In case of the appointment hereunder of a successor Trustee with respect
to the Securities of one or more (but not all) series, the Company, the retiring
Trustee and each successor Trustee with respect to the Securities of one or more
series shall execute and deliver an indenture supplemental hereto wherein each
successor Trustee shall accept such appointment and which (1) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Trustee all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates, (2) if the retiring Trustee
is not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

      Upon request of any such successor Trustee, the Company shall execute any
and all instruments for more fully and certainly vesting in and confirming to
such successor Trustee all such rights, powers and trusts referred to in the
first or second preceding paragraph, as the case may be.


                                      -51-
<PAGE>   61
      No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be qualified and eligible under
this Article.


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

      Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee (including the trust created by this Indenture), shall be the
successor of the Trustee hereunder, provided such corporation shall be otherwise
qualified and eligible under this Article, without the execution or filing of
any paper or any further act on the part of any of the parties hereto. In case
any Securities shall have been authenticated, but not delivered, by the Trustee
then in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Securities
so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities.

SECTION 613.   Preferential Collection of Claims against Company.

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


SECTION 614.   Appointment of Authenticating Agent.

      The Trustee may appoint an Authenticating Agent or Agents with respect to
one or more series of Securities which shall be authorized to act on behalf of
the Trustee to authenticate Securities of such series issued upon original issue
and upon exchange, registration of transfer or partial redemption thereof or
pursuant to Section 306, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this


                                      -52-
<PAGE>   62
Section, the combined capital and surplus of such Authenticating Agent shall be
deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time an Authenticating Agent shall
cease to be eligible in accordance with the provisions of this Section, such
Authenticating Agent shall resign immediately in the manner and with the effect
specified in this Section.

      Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent (including the
authenticating agency contemplated by this Indenture), shall continue to be an
Authenticating Agent, 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 to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice 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 give notice of such
appointment in the manner provided in Section 106 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. 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 Trustee agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section, and the Trustee
shall be entitled to be reimbursed for such payments, subject to the provisions
of Section 607.

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

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

      (2) immediately after giving effect to such transaction and treating any
   indebtedness which becomes an obligation of the Company or any Subsidiary as
   a result of such transaction as having been incurred by the Company or such
   Subsidiary at the time of such transaction, no Event of Default, and no event
   which, after notice or lapse of time or both, would become an Event of

   surrender any right or power herein conferred upon the Company; or

      (3) to add any additional Events of Default for the benefit of the Holders
   of all or any series of Securities (and if such additional Events of Default

      (1) change the Stated Maturity of the principal of, or any installment of
   principal of or interest on, any Security, or reduce the principal amount

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

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


SECTION 903.   Execution of Supplemental Indentures.

      In executing, or accepting the additional trusts created by, any

Trustee in exchange for Outstanding Securities of such series.

                                    COVENANTS


SECTION 1001.     Payment of Principal, Premium and Interest.

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


SECTION 1002.     Maintenance of Office or Agency.

      The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Company in respect of the Securities of that series and this Indenture
may be served. 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, and the Company hereby appoints the Trustee as its agent
to receive all such presentations, surrenders, notices and demands.

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


SECTION 1003.     Money for Securities Payments to Be Held in Trust.

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


                                      -60-
<PAGE>   70
      Whenever the Company shall have one or more Paying Agents for any series
of Securities, it will, prior to each due date of the principal of or any
premium or interest on any Securities of that series, deposit with a Paying
Agent a sum sufficient to pay such amount, such sum to be held as provided by
the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its action or failure so to act.

      The Company will cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will (1) comply with the provisions of
the Trust Indenture Act applicable to it as a Paying Agent and (2) during the
continuance of any default by the Company (or any other obligor upon the
Securities of that series) in the making of any payment in respect of the
Securities of that series, upon the written request of the Trustee, forthwith
pay to the Trustee all sums held in trust by such Paying Agent for payment in
respect of the Securities of that series.

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

      Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of or any premium or
interest on any Security of any series and remaining unclaimed for two years
after such principal, premium or interest has become due and payable shall be
paid to the Company on Company Request, or (if then held by the Company) shall
be discharged from such trust; and the Holder of such Security shall thereafter,
as an unsecured general creditor, look only to the Company for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in New York that,
after a date specified therein, which shall not be less than 30 days from the
date of such publication, any unclaimed balance of such money then remaining
will be repaid to the Company.


SECTION 1004.     Statement by Officers as to Default.

      The Company will deliver to the Trustee, within 120 days after the end of
each fiscal year of the Company ending after the date hereof, an Officers'
Certificate, stating whether or not to the best knowledge of the signers thereof
the Company is in default in the performance and observance of any of the terms,
provisions and conditions of this Indenture (without regard to any period of
grace or requirement of notice provided hereunder) and, if


                                      -61-
<PAGE>   71
the Company shall be in default, specifying all such defaults and the nature and
status thereof of which they may have knowledge.


SECTION 1005.     Existence.

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


SECTION 1006.     Maintenance of Properties.

      The Company will cause all properties used or useful in the conduct of its
business or the business of any Subsidiary to be maintained and kept in good
condition, repair and working order and supplied with all necessary equipment
and will cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in the judgment of the Company may
be necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times; provided, however, that
nothing in this Section shall prevent the Company from discontinuing the
operation or maintenance of any of such properties if such discontinuance is, in
the judgment of the Company, desirable in the conduct of its business or the
business of any Subsidiary and not disadvantageous in any material respect to
the Holders.


SECTION 1007.     Payment of Taxes and Other Claims.

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


SECTION 1008.     Restrictions on Principal Property Liens.

      The Company will not itself, and will not permit any Domestic Subsidiary
to, incur, issue, assume or guarantee any notes, bonds, debentures or other
similar evidences of indebtedness for money borrowed (notes, bonds, debentures
or other similar evidences of indebtedness for money borrowed being hereinafter
in this Section 1008 called "Debt),


                                      -62-
<PAGE>   72
secured by pledge of, or mortgage or other lien on, any Principal Property of
the Company or any Domestic Subsidiary, or any shares of stock or Debt of any
Domestic Subsidiary (pledges, mortgages and other liens being hereinafter in
this Section 1008 called "Mortgage" or "Mortgages"), without effectively
providing that the Securities then Outstanding together with, if the Company
shall so determine, any other Debt of the Company or such Domestic Subsidiary
then existing or thereafter created which is not subordinate to the Securities)
shall be secured equally and ratably with (or prior to) such secured Debt, so
long as such secured Debt shall be so secured, unless, after giving effect
thereto, the aggregate amount of all such secured Debt plus all Attributable
Debt of the Company and its Domestic Subsidiaries in respect of sale and
leaseback transactions as defined in Section 1009 would not exceed 10% of
Consolidated Net Tangible Assets; provided, however, that this Section shall not
apply to, and there shall be excluded from secured Debt in any computation under
this Section, Debt secured by (1) Mortgages on Principal Property of, or on any
shares of stock or Debt of, any corporation existing at the time such
corporation becomes a Domestic Subsidiary; (2) Mortgages in favor of the Company
or any Domestic Subsidiary; (3) Mortgages in favor of the United States of
America, or any agency, department or other instrumentality thereof, to secure
progress, advance or other payments pursuant to any contract or provision of any
statute; (d) Mortgages on Principal Property, shares of stock or Debt existing
at the time of acquisition thereof (including acquisition through merger or
consolidation) or to secure the payment of all or any part of the purchase price
or construction cost thereof or to secure any Debt incurred prior to, at the
time of, or within 120 days after, the acquisition of such Principal Property or
shares or Debt or the completion of any such construction for the purpose of
financing all or any part of the purchase price or construction cost thereof;
and (e) any extension, renewal or replacement (or successive extensions,
renewals or replacements), as a whole or in part, of any Mortgage referred to in
the foregoing clauses (1) to (4) inclusive; provided, that (i) such extension,
renewal or replacement Mortgage shall be limited to all or a part of the same
property, shares of stock or Debt that secured the Mortgage extended, renewed or
replaced (plus improvements on such property) and (ii) the debt secured by such
Mortgage at such time is not increased.


SECTION 1009.     Restriction on Sales and Leasebacks.

      The Company will not itself, and will not permit any Domestic Subsidiary
to, enter into any arrangement with any bank, insurance company or other lender
or investor (not including the Company or any Domestic Subsidiary) or to which
any such lender or investor is party, providing for the leasing by the Company
or a Domestic Subsidiary for a period, including renewals, in excess of three
years of any Principal Property, which has been or is to be sold or transferred,
more than 120 days after the completion of construction and commencement of full
operation thereof, by the Company or any Domestic Subsidiary to such lender or
investor or to any person to whom funds have been or are to be advanced by such
lender or investor on the security of such Principal Property (referred to in
this section as a "sale and leaseback transaction") unless either (1) the
Company or such Domestic Subsidiary could create Debt secured by a Mortgage
pursuant to Section 1008 on the Principal Property or assets to be leased back
in an amount equal to the Attributable Debt with respect to such sale and
leaseback transaction without equally and ratably securing the


                                      -63-
<PAGE>   73
Securities, or (2) the Company or a Domestic Subsidiary, within 120 days after
the sale or transfer shall have been made by such entity, applies an amount
equal to the greater of (i) the net proceeds of the sale of the Principal
Property sold and leased back pursuant to such arrangement or (ii) the fair
market value of the Principal Property so sold and leased back at the time of
entering into such arrangement as determined by the Board of Directors to the
retirement of Funded Debt of the Company; provided, that the amount to be
applied to the retirement of Funded Debt of the Company shall be reduced by (a)
the principal amount of any Securities delivered within 120 days after such sale
to the Trustee for retirement and cancellation and (b) the principal amount of
Funded Debt, other than Securities voluntarily retired by the Company within 120
days after such sale. Notwithstanding the foregoing, no retirement referred to
in this clause (2) may be effected by payment at maturity or pursuant to any
mandatory sinking fund payment or mandatory prepayment provision.


SECTION 1010.     Waiver of Certain Covenants.

      Except as otherwise specified as contemplated by Section 301 for
Securities of such series, the Company may, with respect to the Securities of
any series, omit in any particular instance to comply with any term, provision
or condition set forth in any covenant provided pursuant to Section 301(18),
901(2) or 901(7) for the benefit of the Holders of such series if before the
time for such compliance the Holders of at least 662/3% in principal amount of
the Outstanding Securities of such series shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
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

                            REDEMPTION OF SECURITIES


SECTION 1101.     Applicability of Article.

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


SECTION 1102.     Election to Redeem; Notice to Trustee.

      The election of the Company to redeem any Securities shall be evidenced by
a Board Resolution or in another manner specified as contemplated by Section 301
for such Securities. In case of any redemption at the election of the Company of
less than all the


                                      -64-
<PAGE>   74
Securities of any series (including any such redemption affecting only a single
Security), the Company shall, at least 60 days prior to the Redemption Date
fixed by the Company (unless a shorter notice shall be satisfactory to the
Trustee), notify the Trustee of such Redemption Date, of the principal amount of
Securities of such series to be redeemed and, if applicable, of the tenor of the
Securities to be redeemed. In the case of any redemption of Securities prior to
the expiration of any restriction on such redemption provided in the terms of
such Securities or elsewhere in this Indenture, the Company shall furnish the
Trustee with an Officers' Certificate evidencing compliance with such
restriction.


SECTION 1103.     Selection by Trustee of Securities to Be Redeemed.

      If less than all the Securities of any series are to be redeemed (unless
all the Securities of such series and of a specified tenor are to be redeemed or
unless such redemption affects only a single Security), 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 a
portion of the principal amount of any Security of such series, provided that
the unredeemed portion of the principal amount of any Security shall be in an
authorized denomination (which shall not be less than the minimum authorized
denomination) for such Security. If less than all the Securities of such series
and of a specified tenor are to be redeemed (unless such redemption affects only
a single Security), the particular Securities to be redeemed shall be selected
not more than 60 days prior to the Redemption Date by the Trustee, from the
Outstanding Securities of such series and specified tenor not previously called
for redemption in accordance with the preceding sentence.

      The Trustee shall promptly notify the Company in writing of the Securities
selected for redemption as aforesaid and, in case of any Securities selected for
partial redemption as aforesaid, the principal amount thereof to be redeemed.

      The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting only a single Security, whether such
Security is to be redeemed in whole or in part. In the case of any such
redemption in part, the unredeemed portion of the principal amount of the
Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination) for such Security.

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

<PAGE>   75
SECTION 1104.     Notice of Redemption.

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

      All notices of redemption shall state:

      (1)   the Redemption Date,

      (2)   the Redemption Price,

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

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

      (5) the place or places where each such Security is to be surrendered for
   payment of the Redemption Price, and

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

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

SECTION 1105.     Deposit of Redemption Price.

      Prior to any Redemption Date, the Company shall deposit with the Trustee
or with a Paying Agent (or, if the Company is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 1003) an amount of money
sufficient to pay the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date) accrued interest on, all the Securities which
are to be redeemed on that date.


SECTION 1106.     Securities Payable on Redemption Date.

      Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein


                                      -66-
<PAGE>   76
specified, and from and after such date (unless the Company shall default in the
payment of the Redemption Price and accrued interest) such Securities shall
cease to bear interest. Upon surrender of any such Security for redemption in
accordance with said notice, such Security shall be paid by the Company at the
Redemption Price, together with accrued interest to the Redemption Date;
provided, however, that, unless otherwise specified as contemplated by Section
301, installments of interest whose Stated Maturity is on or prior to the
Redemption Date will be payable to the Holders of such Securities, or one or
more Predecessor Securities, registered as such at the close of business on the
relevant Record Dates according to their terms and the provisions of Section
307.

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


SECTION 1107.     Securities Redeemed in Part.

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


                                 ARTICLE TWELVE

                                  SINKING FUNDS


SECTION 1201.     Applicability of Article.

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

      The minimum amount of any sinking fund payment provided for by the terms
of any Securities 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
such Securities is herein referred to as an "optional sinking fund payment". If
provided for by the terms of any Securities, the cash amount of any sinking fund
payment may be subject to reduction as provided in Section 1202. Each sinking
fund payment shall be applied to the redemption of Securities as provided for by
the terms of such Securities.

<PAGE>   77
SECTION 1202.     Satisfaction of Sinking Fund Payments with Securities.

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


SECTION 1203.     Redemption of Securities for Sinking Fund.

      Not less than 45 days prior to each sinking fund payment date for any
Securities, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, the portion thereof, if
any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting Securities pursuant to
Section 1202 and will also deliver to the Trustee any Securities to be so
delivered. Not less than 30 days prior to each such sinking fund payment date,
the Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 1103 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner provided in Section 1104. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 1106 and 1107.


                                ARTICLE THIRTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE


SECTION 1301.     Company's Option to Effect Defeasance or Covenant Defeasance.

      The Company may elect, at its option at any time, to have Section 1302 or
Section 1303 applied to any Securities or any series of Securities, as the case
may be, designated pursuant to Section 301 as being defeasible pursuant to such
Section 1302 or 1303, in accordance with any applicable requirements provided
pursuant to Section 301 and upon compliance with the conditions set forth below
in this Article. Any such election shall


                                      -68-
<PAGE>   78
be evidenced by a Board Resolution or in another manner specified as
contemplated by Section 301 for such Securities.


SECTION 1302.     Defeasance and Discharge.

      Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, the
Company shall be deemed to have been discharged from its obligations with
respect to such Securities as provided in this Section on and after the date the
conditions set forth in Section 1304 are satisfied (hereinafter called
"Defeasance"). For this purpose, such Defeasance means that the Company shall be
deemed to have paid and discharged the entire indebtedness represented by such
Securities and to have satisfied all its other obligations under such Securities
and this Indenture insofar as such Securities are concerned (and the Trustee, at
the expense of the Company, shall execute proper instruments acknowledging the
same), subject to the following which shall survive until otherwise terminated
or discharged hereunder: (1) the rights of Holders of such Securities to
receive, solely from the trust fund described in Section 1304 and as more fully
set forth in such Section, payments in respect of the principal of and any
premium and interest on such Securities when payments are due, (2) the Company's
obligations with respect to such Securities under Sections 304, 305, 306, 1002
and 1003, (3) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and (4) this Article. Subject to compliance with this Article, the
Company may exercise its option (if any) to have this Section applied to any
Securities notwithstanding the prior exercise of its option (if any) to have
Section 1303 applied to such Securities.


SECTION 1303.     Covenant Defeasance.

      Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, (1)
the Company shall be released from its obligations under Section 801(3),
Sections 1006 through 1009, inclusive, and any covenants provided pursuant to
Section 301(18), 901(2) or 901(7) for the benefit of the Holders of such
Securities, and (2) the occurrence of any event specified in Sections 501(4)
(with respect to any of Section 801(3), Sections 1006 through 1009, inclusive,
and any such covenants provided pursuant to Section 301(18), 901(2) or 901(7)),
501(5) and 501(8) shall be deemed not to be or result in an Event of Default, in
each case with respect to such Securities as provided in this Section on and
after the date the conditions set forth in Section 1304 are satisfied
(hereinafter called "Covenant Defeasance"). For this purpose, such Covenant
Defeasance means that, with respect to such Securities, 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 specified Section (to the extent so specified
in the case of Section 501(4)), whether directly or indirectly by reason of any
reference elsewhere herein to any such Section or by reason of any reference in
any such Section to any other provision herein or in any other document, but the
remainder of this Indenture and such Securities shall be unaffected thereby.

<PAGE>   79
SECTION 1304.     Conditions to Defeasance or Covenant Defeasance.

      The following shall be the conditions to the application of Section 1302
or Section 1303 to any Securities or any series of Securities, as the case may
be:

      (1) The Company shall irrevocably have deposited or caused to be deposited
   with the Trustee (or another trustee which satisfies the requirements
   contemplated by Section 609 and agrees to comply with the provisions of this
   Article 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 benefits of the Holders of such Securities, (A) money in an
   amount, or (B) U.S. Government Obligations 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, money in an amount, or (C) a combination thereof, in each case
   sufficient, 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 any such other qualifying trustee) to pay and discharge, the principal of
   and any premium and interest on such Securities on the respective Stated
   Maturities, in accordance with the terms of this Indenture and such
   Securities. As used herein, "U.S. Government Obligation" means (x) any
   security which is (i) a direct obligation of the United States of America for
   the payment of which the full faith and credit of the United States of
   America is pledged or (ii) an obligation of a Person controlled or supervised
   by and acting as an agency or instrumentality of the United States of America
   the payment of which is unconditionally guaranteed as a full faith and credit
   obligation by the United States of America, which, in either case (i) or
   (ii), is not callable or redeemable at the option of the issuer thereof, and
   (y) any depositary receipt issued by a bank (as defined in Section 3(a)(2) of
   the Securities Act) as custodian with respect to any U.S. Government
   Obligation which is specified in Clause (x) above and held by such bank for
   the account of the holder of such depositary receipt, or with respect to any
   specific payment of principal of or interest on any U.S. Government
   Obligation which is so specified and held, provided that (except as required
   by law) such custodian is not authorized to make any deduction from the
   amount payable to the holder of such depositary receipt from any amount
   received by the custodian in respect of the U.S. Government Obligation or the
   specific payment of principal or interest evidenced by such depositary
   receipt.

      (2) In the event of an election to have Section 1302 apply to any
   Securities or any series of Securities, as the case may be, the Company shall
   have delivered to the Trustee an Opinion of Counsel stating that (A) the
   Company has received from, or there has been published by, the Internal
   Revenue Service a ruling or (B) since the date of this instrument, there has
   been a change in the applicable Federal income tax law, in either case (A) or
   (B) to the effect that, and based thereon such opinion shall confirm that,
   the Holders of such Securities will not recognize gain or loss for Federal
   income tax purposes as a result of the deposit, Defeasance and discharge to
   be effected with respect to such Securities and will be subject to Federal
   income tax on the same amount, in the same manner and at the same times as
   would be the case if such deposit, Defeasance and discharge were not to
   occur.


                                      -70-
<PAGE>   80
      (3) In the event of an election to have Section 1303 apply to any
   Securities or any series of Securities, as the case may be, the Company shall
   have delivered to the Trustee an Opinion of Counsel to the effect that the
   Holders of such Securities will not recognize gain or loss for Federal income
   tax purposes as a result of the deposit and Covenant Defeasance to be
   effected with respect to such Securities and will be subject to Federal
   income tax on the same amount, in the same manner and at the same times as
   would be the case if such deposit and Covenant Defeasance were not to occur.

      (4) The Company shall have delivered to the Trustee an Officer's
   Certificate to the effect that neither such Securities nor any other
   Securities of the same series, if then listed on any securities exchange,
   will be delisted as a result of such deposit.

      (5) No event which is, or after notice or lapse of time or both would
   become, an Event of Default with respect to such Securities or any other
   Securities shall have occurred and be continuing at the time of such deposit
   or, with regard to any such event specified in Sections 501(6) and (7), at
   any time on or prior to the 90th day after the date of such deposit (it being
   understood that this condition shall not be deemed satisfied until after such
   90th day).

      (6) Such Defeasance or Covenant Defeasance shall not cause the Trustee to
   have a conflicting interest within the meaning of the Trust Indenture Act
   (assuming all Securities are in default within the meaning of such Act).

      (7) Such Defeasance or Covenant Defeasance shall not result in a breach or
   violation of, or constitute a default under, any other agreement or
   instrument to which the Company is a party or by which it is bound.

      (8) Such Defeasance or Covenant Defeasance shall not result in the trust
   arising from such deposit constituting an investment company within the
   meaning of the Investment Company Act unless such trust shall be registered
   under such Act or exempt from registration thereunder.

      (9) The Company shall have delivered to the Trustee an Officer's
   Certificate and an Opinion of Counsel, each stating that all conditions
   precedent with respect to such Defeasance or Covenant Defeasance have been
   complied with.


SECTION 1305.     Deposited Money and U.S. Government Obligations to Be
                  Held in Trust; Miscellaneous Provisions.

      Subject to the provisions of the last paragraph of Section 1003, all money
and U.S. Government Obligations (including the proceeds thereof) deposited with
the Trustee or other qualifying trustee (solely for purposes of this Section and
Section 1306, the Trustee and any such other trustee are referred to
collectively as the "Trustee") pursuant to Section 1304 in respect of any
Securities shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and this Indenture, to the payment, either
directly or


                                      -71-
<PAGE>   81
through any such Paying Agent (including the Company acting as its own Paying
Agent) as the Trustee may determine, to the Holders of such Securities, of all
sums due and to become due thereon in respect of principal and any premium and
interest, but money so held in trust need not be segregated from other funds
except to the extent required by law.

      The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1304 or the principal and 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 Outstanding Securities.

      Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or U.S. Government Obligations held by it as provided in Section 1304 with
respect to any Securities 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 the Defeasance or Covenant Defeasance, as
the case may be, with respect to such Securities.


SECTION 1306.     Reinstatement.

      If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 1302 or 1303 shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to Section 1305 with respect to such Securities
in accordance with this Article; provided, however, that if the Company makes
any payment of principal of or any premium or interest on any such Security
following such reinstatement of its obligations, the Company shall be subrogated
to the rights (if any) of the Holders of such Securities to receive such payment
from the money so held in trust.

         States, or

            (ii) the transaction is being executed in, on or through the
