                                    GENERAL


1.   GENERAL INFORMATION.  FURNISH THE FOLLOWING AS TO THE APPLICANT:

     (a)  Form of organization:  A corporation.

     (b)  State or other sovereign power under the laws of which organized:
          Ontario, Canada


2. SECURITIES ACT EXEMPTION APPLICABLE.  STATE BRIEFLY THE FACTS RELIED UPON BY
THE APPLICANT AS A BASIS FOR THE CLAIM THAT REGISTRATION OF THE INDENTURE
SECURITIES UNDER THE SECURITIES ACT OF 1933 IS NOT REQUIRED.

     On June 25, 1999, the applicant, Philip Services Corp., an Ontario
corporation (the "Company" or the "Debtor"), together with its wholly owned
subsidiary, Philip Services (Delaware), Inc., a Delaware corporation ("PSI"),
and certain of their subsidiaries filed a voluntary application with the
Ontario Superior Court of Justice in Toronto, Canada, to reorganize under the
Companies Creditors Arrangement Act (Canada) (the "CCAA") and voluntary
petitions with the United States Bankruptcy Court for the District of Delaware
(the "Bankruptcy Court"), under Chapter 11 of the United States Bankruptcy
Code, 11 U.S.C. sections 101-1330, as amended (the "Bankruptcy Code").  On June
27, 1999, the Company obtained First Day Orders under Chapter 11 of the United
States Bankruptcy Code from the Bankruptcy Court.  On September 17, 1999 the
Company filed an Amended and Restated Plan of Compromise and Arrangement under
the CCAA with the Ontario Superior Court of Justice in Toronto, Canada, and an
Amended Joint Plan of Reorganization and a Disclosure Statement under Chapter
11 with the Bankruptcy Court.  On September 21, 1999 the Company filed a
further Amended and Restated Plan of Compromise and Arrangement (the "Amended
Canadian Plan") under the CCAA with the Ontario Superior Court of Justice in
Toronto, Canada, and an Amended Joint Plan of Reorganization (the "Amended U.S.
Plan", and together with the Amended Canadian Plan, the "Plan") and a
Disclosure Statement under Chapter 11 with the Bankruptcy Court.  A confirmation
hearing to confirm the Amended U.S. Plan is scheduled for November 3, 1999 at
the Bankruptcy Court.

     The Company proposes to issue, as part of the Amended U.S. Plan, pursuant
to section 1121(a) of the Bankruptcy Code, up to $18 million of its 3%
Convertible Subordinated Notes due 2019 (the "Notes").  The Notes will be issued
to discharge, in part, claims of certain existing creditors in the bankruptcy
proceedings described below.

     The Notes are proposed to be issued in reliance upon the exemption from
registration under the Securities Act of 1933, as amended (the "Securities
Act"), set forth in section 1145(a)(1) of the Bankruptcy Code.  Section 1145 of
the Bankruptcy Code exempts the offer or sale of securities under a plan of
reorganization from registration under the Securities Act and state law.  Under
section 1145, the issuance of securities is exempt from registration if three
principal requirements are satisfied: (1) the securities are issued by a
debtor, its successor, or an affiliate participating in a joint plan with the
debtor (provided that such entity is not an underwriter as defined in section
1145(b) of the Bankruptcy Code) under a plan of reorganization; (2) the
recipients of the securities hold a claim against the debtor or such affiliate,
an interest in the debtor or such affiliate, or a claim for an administrative
expense against the debtor or such affiliate; and (3) the securities are issued
entirely in exchange for the recipients' claims against or interests in the
debtor or such affiliate, or "principally" in such exchange and "partly" for
cash or property.

     The Company believes that the issuance of the Notes under the indenture to
be entered into by the Company and                , as Trustee (the "Indenture")
to holders of prepetition claims under the Amended U.S. Plan will satisfy all
three conditions of section 1145 of the Bankruptcy Code because (a) the
issuances are expressly contemplated under the Amended U.S. Plan as part of the
reorganization; (b) the recipients are holders of "claims" against the Debtor or
an affiliate of the Debtor participating in the  Amended U.S. Plan with the
Debtor; and (c) the recipients would obtain the Notes in exchange for their
claims.

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

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

or the authority of the Person executing the same, may also be proved in any
other manner which the Trustee deems sufficient.

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

     The Company may set any day as a record date for the purpose of determining
the Holders of Outstanding Securities entitled to give, make or take any
request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Indenture to be given, made or taken by
Holders of Securities, provided that the Company may not set a record date for,
and the provisions of this paragraph shall not apply with respect to, the giving
or making of any notice, declaration, request or direction referred to in the
next paragraph. If not set by the Company prior to the first solicitation of a
Holder made by any Person in respect of any such matter referred to in the
foregoing sentence, the record date for any such matter shall be the 30th day
(or, if later, the date of the most recent list of Holders required to be
provided pursuant to Section 701) prior to such first solicitation. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities on such record date, and no other Holders, shall be entitled to take
the relevant action, 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 on such record date. Nothing in this
paragraph shall be construed to prevent the Company 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 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 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 in the manner
set forth in Section 106.

     The Trustee may set any day as a record date for the purpose of determining
the Holders of Outstanding Securities entitled to join in the giving or making
of (i) any Notice of Default, (ii) any declaration of 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. If any record
date is set pursuant to this paragraph, the Holders of Outstanding Securities 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 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 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 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 in the manner set forth in Section 106.




                                       12

<PAGE>   23



     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 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 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 or to it at [NAME AND
     ADDRESS OF TRUSTEE] Attention: --, 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.




                                       13

<PAGE>   24



     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.

     Until such time as this Indenture shall be qualified under the Trust
Indenture Act, this Indenture, the Company and the Trustee shall be deemed for
all purposes hereof to be subject to and governed by the Trust Indenture Act to
the same extent as would be the case if this Indenture were so qualified on the
date hereof. If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be a
part of and govern this Indenture, the latter provision shall control. If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or to be excluded, as the case
may be.

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

give to any Person, other than the parties hereto and their successors hereunder

     In any case where any Interest Payment Date, Redemption Date, Purchase Date
or Stated Maturity of any Security or the last day on which a Holder of a
Security has a right to convert his Security shall not be a Business Day, then
(notwithstanding any other provision of this Indenture or of the


                                       14

<PAGE>   25

not be made on such date, but may be made on the next succeeding Business Day

Redemption Date, or Purchase Date, or Stated Maturity or last day for
conversion, as the case may be.

jurisdiction of the courts of its own corporate domicile in any legal suit,
action or proceeding arising out of or relating to this Indenture or the
Securities. The Company hereby designates and appoints [CT CORPORATION SYSTEM,
1633 BROADWAY, NEW YORK, NEW YORK 10019] as its authorized agent upon which
process may be served in any legal suit, action or proceeding arising out of or
relating to this Indenture or the Securities which may be instituted in any
federal or state court in the Borough of Manhattan, The City of New York, New

every respect effective service of process upon the Company in any such suit,
action or proceeding and further designates its domicile, the domicile of

the Company will promptly appoint a successor agent for this purpose reasonably
acceptable to the Trustee. The Company agrees to take any and all actions as may
be necessary to maintain such designation and appointment of such agent in full

SECTION 203. Form of Reverse of Security.

     This Security is one of a duly authorized issue of Securities of the
Company designated as its 3% Convertible Subordinated Notes due --, 2019 (herein
called the "Securities"), limited in aggregate principal amount to $--, issued
and to be issued under an Indenture, dated as of --, 1999 (herein called the
"Indenture"), between the Company and [NAME OF TRUSTEE], as Trustee (herein
called the "Trustee", which term includes any successor trustee under the
Indenture), to which Indenture and all indentures supplemental thereto reference
is hereby made for a statement of the respective rights, limitations of rights,
duties and immunities thereunder of the Company, the Trustee and the Holders of
the Securities and of the terms upon which the Securities are, and are to be,
authenticated and delivered.

     Upon the occurrence of a Redemption Change of Control, the Securities are
subject to redemption upon not less than 30 nor more than 60 days' notice by
mail, as a whole or in part, at the election of the Company, at a Redemption
Price equal to 100% of the principal amount then outstanding, together in the
case of any such redemption with accrued interest to but excluding the
Redemption Date, but interest installments whose Stated Maturity is on or prior
to such Redemption Date will be payable to the Holders of such Securities, or
one or more Predecessor Securities, of record at the close of business on the
relevant Regular Record Dates referred to on the face hereof, all as provided in
the Indenture.

     Subject to and upon compliance with the provisions of the Indenture, the
Holder of this Security is entitled, at its option, at any time, or in case this
Security or a portion hereof is called for redemption or the Holder hereof has
tendered this Security or a portion thereof to an Offer to Purchase, then in
respect of this Security until and including, but (unless the Company defaults
in making the payment due upon redemption or purchase, as the case may be) not
after, the close of business on the Redemption Date or the Purchase Date, as the
case may be, to convert this Security (or any portion of the principal amount
hereof that is an integral multiple of $1.00), into fully paid and nonassessable
Common Shares of the Company at an initial Conversion Price of $30.00 for each
Common Share (or at the current adjusted Conversion Price if an adjustment has
been made as provided in the Indenture) by surrender of this Security, duly
endorsed or assigned to the Company or in blank and, in case such surrender
shall be made during the period from the close of business of any Regular Record
Date next preceding any Interest Payment Date to the opening of business on such
Interest Payment Date ("Interest Period") (except Securities called for
redemption on a Redemption Date or to be purchased on a Purchase Date during, in
each case, such Interest Period), also accompanied by payment in same day or
other funds acceptable to the Company of an amount equal to the interest payable
on such Interest Payment Date on the principal amount of this Security then
being converted, and also the conversion notice hereon duly executed, to the
Company at the Corporate Trust Office of the Trustee, or at such other office or
agency of the Company, subject to any laws or regulations applicable thereto and
subject to the right of the Company to terminate the appointment of any
Conversion Agent as may be designated by it for such purpose in the Borough of
Manhattan, The City of New York, or at such other offices or agencies as the
Company may designate (each a Conversion Agent). Subject to the aforesaid
requirement for payment and, in the case of a conversion after the Regular
Record Date next preceding any Interest Payment Date and on or before such
Interest Payment Date, to the right of the Holder of this Security (or any
Predecessor Security) of record at such Regular Record Date to receive an
installment of interest, no cash payment or adjustment is to be made on
conversion, if the date of conversion is not an Interest Payment Date, for
interest accrued hereon from the Interest Payment Date next preceding the date
of conversion, or for dividends on the Common Shares issued on conversion
hereof. The Company shall thereafter deliver to the Holder the fixed number of
shares of Common Shares (together with any cash adjustment, as provided in the
Indenture) into which


                                       20

<PAGE>   31



this Security is convertible and such delivery will be deemed to satisfy the
Company's obligation to pay the principal amount of this Security. No fractions
of shares or scrip representing fractions of shares will be issued on
conversion, but instead of any fractional interest (calculated to the nearest
1/100th of a share) the Company shall pay a cash adjustment as provided in the
Indenture. The Conversion Price is subject to adjustment as provided in the
Indenture. In addition, the Indenture provides that in case of certain
amalgamations, consolidations or mergers to which the Company is a party or the
transfer of all or substantially all of the property and assets of the Company,
the Indenture shall be amended, without the consent of any holders of
Securities, so that this Security, if then Outstanding, will be convertible
thereafter, during the period this Security shall be convertible as specified
above, only into the kind and amount of securities, cash and other property
receivable upon such amalgamation, consolidation, merger or transfer by a holder
of the number of Common Shares of the Company into which this Security could
have been converted immediately prior to such amalgamation, consolidation,
merger or transfer [SUBJECT, HOWEVER, TO ANY REQUIREMENTS NECESSARY TO ENSURE
THAT THE SECURITIES WILL BE AND WILL REMAIN EXEMPT FROM CANADIAN WITHHOLDING TAX
INCLUDING, WITHOUT LIMITATION, THE REQUIREMENT IN EFFECT ON THE DATE HEREOF THAT
A HOLDER OF SECURITIES SHALL NOT BE ENTITLED TO RECEIVE SHARES, OTHER SECURITIES
OR PROPERTY, OTHER THAN SHARES THAT ARE "PRESCRIBED SECURITIES" AS DEFINED IN
REGULATION 6208 TO THE INCOME TAX ACT (CANADA) IN THE EVENT THAT ANY SUCH
AMALGAMATION, CONSOLIDATION, MERGER OR TRANSFER OCCURS ON OR PRIOR TO FIVE YEARS
AFTER THE DATE OF ORIGINAL ISSUE OF THE SECURITIES (ASSUMING SUCH HOLDER OF
COMMON SHARES IS NOT A CONSTITUENT PERSON, FAILED TO EXERCISE ANY RIGHTS OF
ELECTION AND RECEIVED PER SHARE THE KIND AND AMOUNT RECEIVED PER SHARE BY A
PLURALITY OF NON-ELECTING SHARES AND FURTHER ASSUMING, IF SUCH AMALGAMATION,
CONSOLIDATION, MERGER OR TRANSFER OCCURS PRIOR TO THE LATER OF 60 DAYS FOLLOWING
THE LATEST OF (I) -- AND (II) THE LATEST DATE OF ORIGINAL ISSUE OF ANY SECURITY,
THAT THE SECURITY WAS CONVERTIBLE AT THE TIME OF SUCH OCCURRENCE AT THE
CONVERSION PRICE SPECIFIED ABOVE AS ADJUSTED FROM THE ISSUE DATE OF SUCH
SECURITY TO SUCH TIME AS PROVIDED IN THE INDENTURE)]. No adjustment in the
Conversion Price will be made until such adjustment would require an increase or
decrease of at least one percent of such price, provided that any adjustment
that would otherwise be made will be carried forward and taken into account in
the computation of any subsequent adjustment.

     The Indenture provides that, subject to certain conditions, if a Change of
Control occurs, the Company shall be required to make an Offer to Purchase for
all of the Securities at the following prices (expressed as percentages of the
principal amount) if the Purchase Date is during the 12-month period beginning
- -- of each of the years indicated below:

and thereafter at a price equal to 100% of the principal amount, in each case
plus accrued interest to the Purchase Date (provided, however, that installments
of interest whose Stated Maturity is on or prior to the Purchase Date shall be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates).

     In the event of redemption, purchase or conversion of this Security in part
only, a new Security or Securities for the unredeemed, unpurchased or
unconverted portion hereof will be issued in the name of the Holder hereof upon
the cancellation hereof.

     The indebtedness evidenced by this Security is, to the extent and in the
manner provided in the Indenture, subordinate and subject in right of payment to
the prior payment in full of all Senior Indebtedness of the Company, and this
Security is issued subject to such provisions of the Indenture with respect
thereto. Each Holder of this Security, by accepting the same, (a) agrees to and
shall be bound by such provisions, (b) authorizes and directs the Trustee on his
behalf to take such action as may be necessary or appropriate to effectuate the
subordination so provided and (c) appoints the Trustee his attorney-in-fact for
any and all such purposes.

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

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities under the Indenture at
any time by the Company and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Securities at the time
Outstanding. The Indenture also contains provisions permitting the Holders of
specified percentages in aggregate principal amount of the Securities at the
time Outstanding, on behalf of the Holders of all the Securities, to waive
compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or
waiver by the Holder of this Security shall be conclusive and binding upon such
Holder and upon all future Holders of this Security and of any Security issued
upon the registration of transfer hereof or in exchange herefor or in lieu
hereof, whether or not notation of such consent or waiver is made upon this
Security.

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

     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 the Borough of Manhattan, The City of New York, 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 authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

     The Securities are issuable only in registered form without coupons in
denominations of $1.00 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations


                                       22

<PAGE>   33



therein set forth, Securities are exchangeable for a like aggregate principal
amount of Securities of a different authorized denomination, as requested by the
Holder surrendering the same.

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

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

     Interest on this Security shall be computed on the basis of a 360-day year
of twelve 30-day months. The yearly rate of interest that is equivalent to the
rate payable under the Securities is the rate payable multiplied by the actual
number of days in the year and divided by 360 and is disclosed herein solely for
purpose of providing the disclosure required by the Interest Act (Canada).

     All terms used in this Security which are defined in the Indenture shall
have the meanings assigned to them in the Indenture.

     The Indenture and this Security shall be governed by and construed in
accordance with the laws of the State of New York.

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities 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 such Company
Order shall authenticate and deliver such Securities as in this Indenture
provided and not otherwise.

     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.

     In case the Company, pursuant to Article Eight, shall be amalgamated,
consolidated or merged with or into any other Person or shall convey, transfer,
lease or otherwise dispose of substantially all of its properties and assets to
any Person, and the successor Person resulting from such amalgamation,
consolidation, or surviving such merger, or into which the Company shall have

consolidation, merger, conveyance, transfer, lease or other disposition may,
from time to time, at the request of the successor Person, be exchanged for
other Securities executed in the name of the successor Person with such changes
in phraseology and form as may be appropriate, but otherwise in substance of
like tenor as the Securities surrendered for such exchange and of like principal
amount; and the Trustee upon Company Order of the successor Person, shall
authenticate and deliver replacement Securities as specified in such request for
the purpose of such exchange. If replacement Securities shall at any time be
authenticated and delivered in any new name of a successor Person pursuant to
this Section in exchange or substitution for or upon registration of transfer of
any Securities, such successor Person, at the option of any Holder but without
expense to such Holder, shall provide for the exchange of all Securities at the
time outstanding held by such Holder for Securities authenticated and delivered
in such new name.

SECTION 304. Temporary Securities.

     Pending the preparation of definitive Securities, 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 are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay. After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at any office
or agency of the Company designated pursuant to Section 1002, without charge to
the Holder. Upon surrender for cancellation of any one or more temporary
Securities the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like principal amount of definitive Securities


                                       25

of authorized denominations. Until so exchanged the temporary Securities shall
in all respects be entitled to the same benefits under this Indenture as
definitive Securities.

SECTION 305. Registration, Registration of Transfer and Exchange.

     (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 designated pursuant to Section 1002 being herein sometimes collectively
referred to as the "Security Register") in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration
of Securities and of transfers and exchanges of Securities. The Trustee is
hereby appointed "Security Registrar" for the purpose of registering Securities
and transfers and exchanges of Securities as herein provided. Such Security
Register shall distinguish between Original Securities and Exchange Securities.

     Upon surrender for registration of transfer of any Security at an office or
agency of the Company designated pursuant to Section 1002 for such purpose, 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
any authorized denominations and of a like aggregate principal amount bearing
such restrictive legends as may be required by this Indenture.

     At the option of the Holder, and subject to the other provisions of this
Section 305, Securities may be exchanged for other Securities of any authorized
denominations and of a like aggregate principal amount, upon surrender of the
Securities to be exchanged at such office or agency. Whenever any Securities are
so surrendered for exchange, and subject to the other provisions of this Section
305, 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 Security Registrar) 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 transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906, 1108, 1202 or 1401.

     The Company shall not be required (i) to issue, register the transfer of or
exchange any Security during a period beginning at the opening of business 15
days before the day of the mailing of a notice of redemption of Securities
selected for redemption under Section 1104 and ending at the close of business
on the day of such mailing, or (ii) to register the transfer of or exchange any
Security so selected for redemption in whole or in part, except the unredeemed
portion of any Security being redeemed in part.

     The provisions of clauses (1), (2), (3), (4) and (5) below shall apply only
to Global Securities:

          (1) Each Global Security authenticated under this Indenture shall be
     registered in the name of the U.S. Depositary or a nominee thereof and
     delivered to the U.S. 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 or the
     Securities, 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 U.S.
     Depositary or a nominee thereof unless (A) the U.S. Depositary (i) has
     notified the Company that it is unwilling or unable to continue as U.S.
     Depositary for such Global Security or (ii) has ceased to be a clearing
     agency registered under the Exchange Act, and in either case the Company
     thereupon fails to appoint a successor depositary within 120 days of such
     notice, (B) the Company, at its option, executes and delivers to the
     Trustee a Company Order that such Global Security shall be exchanged in
     whole for Securities that are not Global Securities, or (C) there shall
     have occurred and be continuing an Event of Default with respect to such
     Global Security.

          (3) Securities issued in exchange for a Global Security or any portion
     thereof pursuant to clause (2) above shall be issued in definitive, fully
     registered form, without interest coupons, shall have an aggregate
     principal amount equal to that of such Global Security or portion thereof
     to be so exchanged, shall be registered in such names and be in such
     authorized denominations as the U.S. Depositary shall designate and shall
     bear any legends required hereunder. Any Global Security to be exchanged in
     whole shall be surrendered by the U.S. Depositary to the Trustee, as
     Security Registrar. With regard to any Global Security to be exchanged in
     part, either such Global Security shall be so surrendered for exchange or,
     if the Trustee is acting as custodian for the U.S. Depositary or its
     nominee with respect to such Global Security, the principal amount thereof
     shall be reduced, by an amount equal to the portion thereof to be so
     exchanged, by means of an appropriate adjustment made on the records of the
     Trustee. Upon any such surrender or adjustment, the Trustee shall
     authenticate and deliver the Security issuable on such exchange to or upon
     the order of the U.S. Depositary or an authorized representative thereof.

          (4) In the event of the occurrence of any of the events specified in
     clause (2) above, the Company will promptly make available to the Trustee a
     reasonable supply of certificated Securities in definitive, fully
     registered form, without interest coupons.

          (5) Neither any members of, or participants in, the U.S. Depositary
     ("Agent Members") nor any other Persons on whose behalf Agent Members may
     act shall have any rights under this Indenture with respect to any Global
     Security, or under any Global Security, and the U.S. Depositary or such
     nominee, as the case may be, may be treated by the Company, the Trustee and
     any agent of the Company or the Trustee as the absolute owner and Holder of
     such Global Security for all purposes whatsoever. Notwithstanding the
     foregoing, nothing herein shall prevent the Company, the Trustee or any
     agent of the Company or the Trustee from giving effect to any written
     certification, proxy or other authorization furnished by the U.S.
     Depositary or such nominee, as the case may be, or impair, as between the
     U.S. Depositary, its Agent Members and


                                       27

<PAGE>   38



     any other person on whose behalf an Agent Member may act, the operation of
     customary practices of such Persons governing the exercise of the rights of
     a Holder of any Security.

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 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 mutilation, 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 upon its request the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security 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, but
subject to any conversion rights, instead of issuing a new Security, pay such
Security.

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

     Every new Security issued pursuant to this Section in lieu of any
mutilated, 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 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.

     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 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:




                                       28

<PAGE>   39



          (1) The Company may elect to make payment of any Defaulted Interest to
     the Persons in whose names the Securities (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 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 expense of the Company,
     shall cause notice of the proposed payment of such Defaulted Interest and
     the Special Record Date therefor to be mailed, first-class postage prepaid,
     to each Holder at his address as it appears in the Security Register, not
     less than 10 days prior to such Special Record Date. Notice of the proposed
     payment of such Defaulted Interest and the Special Record Date therefor
     having been so mailed, such Defaulted Interest shall be paid to the Persons
     in whose names the Securities (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 in any
     other lawful manner not inconsistent with the requirements of any
     securities exchange on which the Securities may be listed, and upon such
     notice as may be required by such exchange, if, after notice given by the
     Company to the Trustee of the proposed payment pursuant to this 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.

     In the case of any Security which is converted after any Regular Record
Date and on or prior to the next succeeding Interest Payment Date (other than
any Security whose Maturity is prior to such Interest Payment Date), interest
whose Stated Maturity is on such Interest Payment Date shall be payable on such
Interest Payment Date notwithstanding such conversion, and such interest
(whether or not punctually paid or duly provided for) shall be paid to the
Person in whose name such Security (or one or more Predecessor Securities) is
registered at the close of business on such Regular Record Date. Except as
otherwise expressly provided in the immediately preceding sentence, in the case
of any Security which is converted, interest whose Stated Maturity is after the
date of conversion of such Security shall not be payable.

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


                                       29

<PAGE>   40



(subject to Section 307) 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, purchase, registration
of transfer or exchange or conversion shall, if surrendered to any Person other
than the Trustee, be delivered to the Trustee and shall be promptly cancelled by
it. The Company shall deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the Company may have
acquired in any manner whatsoever, and all Securities so delivered shall be
promptly cancelled by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities cancelled as provided in this Section,
except as expressly permitted by this Indenture. All cancelled Securities held
by the Trustee shall be disposed of by the Trustee in accordance with its
customary procedures and certification of their disposal delivered to the
Company unless by Company Order the Company shall direct that cancelled
Securities be returned to it.

SECTION 310. Computation of Interest.

     Interest on the Securities shall be computed on the basis of a 360-day year
of twelve 30-day months.

SECTION 311. Interest Act (Canada).

     For purposes of the Interest Act (Canada) any interest rate determined
hereunder on the basis of a 360-day year expressed as an annual rate, shall be
equivalent to the said rate multiplied by the actual number of days in the
calendar year in which it is determined and divided by 360.

                           Satisfaction and Discharge

SECTION 401. Satisfaction and Discharge of Indenture.

     This Indenture shall cease to be of further effect (except as to any
surviving rights of conversion, or registration of transfer or exchange of
Securities herein expressly provided for), and the Trustee, upon a Company Order
and at the expense of the Company, shall execute proper instruments
acknowledging satisfaction and discharge of this Indenture (including, but not
limited to, Article Twelve hereof), 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 (whether on the Purchase
               Date, upon an election by a Holder to convert its Securities or
               otherwise), 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 an amount sufficient to pay and
               discharge the entire indebtedness on such Securities not
               theretofore delivered to the Trustee for cancellation, for
               principal and interest to the date of such deposit (in the case
               of Securities which have become due and payable) or to the
               Purchase Date, 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 pursuant to
this Article Four, the obligations of the Company to the Trustee under Section
607 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.

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 interest for
whose payment such money has been deposited with the Trustee.

it or any Paying Agent) for the payment of Securities subsequently converted
shall be returned to the Company upon Company Request.

SECTION 502. Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default (other than an Event of Default specified in Section
501(9) or (10)) occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities may declare the principal of all the Securities 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 and
any accrued interest shall become immediately due and payable; provided,
however, that so long as the Credit Agreement shall be in full force and effect,
if an Event of Default shall have occurred and be continuing (other than an
Event of Default specified in Section 501(9) or (10)), the Securities shall not
become due and payable until the earlier to occur of (x) five


                                       33

<PAGE>   44



Business Days following delivery of written notice of such acceleration of the
Securities to the agent under the Credit Agreement and (y) the acceleration
(ipso facto or otherwise) of any indebtedness under the Credit Agreement.

     If an Event of Default specified in Section 501(9) or (10) occurs, the
principal of and any accrued interest on the Securities then Outstanding shall
ipso facto become immediately due and payable without any declaration or other
Act on the part of the Trustee or any Holder.

     At any time after such a declaration of acceleration has been made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee as hereinafter in this Article provided, the Holders of a majority
in principal amount of the Outstanding Securities, 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 Outstanding Securities,

               (B) the principal of any Outstanding Securities which have become
          due otherwise than by such declaration of acceleration and, to the
          extent that payment of such interest is lawful, interest thereon at
          the rate provided by the Outstanding Securities,

               (C) to the extent that payment of such interest is lawful,
          interest upon overdue interest at the rate provided by the 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, other than the non-payment of the principal
     of Securities 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 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 interest, and, to the extent that


                                       34

<PAGE>   45



payment of such interest shall be legally enforceable, interest on any overdue
principal and on any overdue interest, at the rate provided by the Securities,
and, in addition thereto, such further amount as shall be sufficient to cover
the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

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

     If an Event of Default occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders 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.

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

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

SECTION 506. Application of Money Collected.

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

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

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

SECTION 507. Limitation on Suits.

     No Holder of any Security 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;

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

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

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

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

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.

     Notwithstanding anything contained herein to the contrary, at any time when
the Company is prohibited from making any payment of principal of, premium (if
any) on, or interest on the Securities as described in Article 13, neither the
Trustee nor the Holders may (A) accelerate the maturity of the principal of, or
premium, if any, or accrued interest on the Securities, (B) commence any action
or proceeding (including the right to set off) to collect payment of the
principal of or premium, if any or accrued interest on the Securities, or (C)
commence an involuntary case or proceeding in bankruptcy against the Company or
seek the appointment of a receiver, custodian or trustee with respect to the
assets of the Company; provided that the restrictions set forth in the foregoing
clauses (A), (B), and (C) shall not apply upon the commencing of any bankruptcy,
dissolution, winding up, liquidation or reorganization of the Company by any
Persons other than the Trustee or the Holders.

<PAGE>   47



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

     Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of and (subject to Section 307) interest on such
Security on the respective Stated Maturities expressed in such Security (or, in
the case of redemption or purchase, on the Redemption Date or Purchase Date, as
the case may be) 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.

SECTION 510. Rights and Remedies Cumulative.

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in 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 Security to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or 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
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, 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.



                                       37

<PAGE>   48



SECTION 513. Waiver of Past Defaults.

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

          (1) in the payment of the principal of or interest on any Security
     (including any Security which is required to have been purchased pursuant
     to an Offer to Purchase which has been made by the Company), 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 affected.

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

SECTION 514. Undertaking for Costs.

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

SECTION 515. Waiver of Stay or Extension Laws.

     The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage or 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 6

                                   The Trustee

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


                                       38

<PAGE>   49



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.

     The Trustee shall give the Holders notice of any default hereunder 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(6), 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.

SECTION 603. Certain Rights of Trustee.

          Subject to the provisions of Section 601:

          (a) the Trustee may rely and shall be protected in acting or
     refraining from acting upon any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, other evidence of indebtedness or other paper or

     sufficiently evidenced by a Company Request or Company Order and any
     resolution of the Board of Directors may be sufficiently evidenced by a

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

          (d) 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;

          (e) 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;

          (f) 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


                                       39

<PAGE>   50



     investigation, it shall be entitled to examine the books, records and
     premises of the Company, personally or by agent or attorney; and

          (g) the Trustee may execute any of the trusts or powers hereunder or
     perform any duties hereunder either directly or by or through agents or
     attorneys and the Trustee shall not be responsible for any misconduct or
     negligence on the part of any agent or attorney appointed with due care by
     it 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 the Trustee assumes no responsibility for their correctness. The Trustee
makes no representations as to the validity or sufficiency of this Indenture, of
the Securities or the Common Stock issuable upon the conversion of the
Securities. The Trustee shall not 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 Conversion
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, any Conversion 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


                                       40

<PAGE>   51



     the acceptance or administration of this trust, 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. Disqualification: 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.

SECTION 609. Corporate Trustee Required; Eligibility.

     There shall at all times be a Trustee hereunder which shall be a Person
that is eligible pursuant to the Trust Indenture Act to act as such. Any
successor Trustee shall have a combined capital and surplus of at least
$50,000,000. If such Person publishes reports of condition at least annually,
pursuant to law or to the requirements of said supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such Person shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time
the Trustee shall cease to be eligible in accordance with the provisions of this
Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

SECTION 610. Resignation and Removal; Appointment of Successor.

     (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 611.

     (b) The Trustee may resign at any time by giving written notice thereof to
the Company. If an instrument of acceptance by a successor Trustee 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.

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

     (d) If at any time:

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

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

          (3) the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent or a receiver of the Trustee or of its property
     shall be appointed or any public officer


                                       41

<PAGE>   52



     shall take charge or control of the Trustee or of its property or affairs
     for the purpose of rehabilitation, conservation or liquidation,

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

     (e) If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, the Company,
by a Board Resolution, shall promptly appoint a successor Trustee. If, within
one year after such resignation, removal or incapability, or the occurrence of
such vacancy, a successor Trustee shall be appointed by Act of the Holders of a
majority in principal amount of the Outstanding Securities delivered to the
Company and the retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment, become the successor Trustee
and supersede the successor Trustee appointed by the Company. If no successor
Trustee shall have been so appointed by the Company or the Holders and accepted
appointment in the manner hereinafter provided, 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 appointment of a successor Trustee.

     (f) The Company shall give notice of each resignation and each removal of
the Trustee and each appointment of a successor Trustee to all Holders in the
manner provided in Section 106. Each notice shall include the name of the
successor Trustee and the address of its Corporate Trust Office.

SECTION 611. Acceptance of Appointment by Successor.

     Every successor Trustee appointed hereunder 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 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. 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.

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

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

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any


                                       42

<PAGE>   53



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 which shall be
authorized to act on behalf of the Trustee to authenticate Securities issued
upon original issue and upon exchange, registration of transfer, partial
conversion, partial purchase or partial redemption 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 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 to 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, shall continue to be an
Authenticating Agent, provided such corporation shall otherwise be 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 mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders as their
names and addresses appear in the


                                       43

<PAGE>   54



Security Register. 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.


                                       44

<PAGE>   55



     If an appointment is made pursuant to this Section, the Securities may have

<PAGE>   58



          (5) to cure any ambiguity, to correct or supplement any provision
     herein which may be inconsistent with any other provision herein, or to
     make any other provisions with respect to matters or questions arising
     under this Indenture which shall not be inconsistent with the provisions of

SECTION 902. Supplemental Indentures with Consent of Holders.

     With the consent of the Holders of not less than a majority in principal
amount of the Outstanding Securities, by Act of said Holders delivered to the

     impair the right to institute suit for the enforcement of any such payment
     on or after the Stated Maturity thereof (or, in the case of redemption or
     any purchase, on or after the Redemption Date or Purchase Date, as the case
     may be), or except as permitted by Section 1211, adversely affect the right

     Purchase pursuant to Section 1401, modify the provisions of this Indenture
     with respect to such Offer to Purchase in a manner adverse to such Holder.

approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

SECTION 903. Execution of Supplemental Indentures.

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

SECTION 904. Effect of Supplemental Indentures.

     Upon the execution of any supplemental indenture under this Article, this
Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby. No such supplemental indenture shall directly or
indirectly modify the provisions of Article Thirteen in any manner which might
terminate or impair the rights of the Senior Debt pursuant to such subordination
provisions.

SECTION 905. Conformity with Trust Indenture Act.

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

SECTION 906. Reference in Securities to Supplemental Indentures.

     Securities authenticated and delivered after the execution of any

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

                                   ARTICLE 10

                                    Covenants

SECTION 1001. Payment of Principal and Interest.

     The Company will duly and punctually pay the principal of and interest on
the Securities in accordance with the terms of the Securities and this
Indenture.

SECTION 1002. Maintenance of Office or Agency.

     The Company will maintain in the Borough of Manhattan, The City of New
York, an office or agency where Securities may be presented or surrendered for
payment, where Securities may be surrendered for registration of transfer or
exchange, where Securities may be surrendered for conversion and where notices
and demands to or upon the Company in respect of the Securities and this
Indenture may


                                       49

<PAGE>   60



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 (in or outside the Borough of Manhattan, The City of New York) where
the Securities 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 the Borough of Manhattan, The City
of New York, 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 Security Payments to be Held in Trust.

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

     Whenever the Company shall have one or more Paying Agents, it will, prior
to each due date of the principal of or interest on any Securities, deposit with
a Paying Agent a sum sufficient to pay the principal or interest so becoming
due, such sum to be held in trust for the benefit of the Persons entitled to
such principal or interest, 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 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) hold all sums held by it for the payment of the principal of or
     interest on Securities in trust for the benefit of the Persons entitled
     thereto until such sums shall be paid to such Persons or otherwise disposed
     of as herein provided;

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

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

     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying


                                       50

<PAGE>   61



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

SECTION 1004. 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 in good faith 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 1005. Maintenance of Properties.

     The Company will cause all properties used or useful in the conduct of its
business or the business of any Subsidiary of the Company 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, as determined by the Board of Directors in good faith,
desirable in the conduct of its business or the business of any Subsidiary and
not disadvantageous in any material respect to the Holders.

SECTION 1006. 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 of its Subsidiaries or upon
the income, profits or property of the Company or any of its Subsidiaries, and
(2) all lawful claims for labor, materials and supplies which, if unpaid, might
by law become a lien upon the property of the Company or any of its
Subsidiaries; provided, however, that the Company shall not be required to pay
or discharge or cause to be paid or discharged any such tax,


                                       51

<PAGE>   62



assessment, charge or claim whose amount, applicability or validity is being
contested in good faith by appropriate proceedings.

SECTION 1007. Registration and Listing.

     (1) Prior to the time the Securities become convertible, the Company will
effect all registrations with, and obtain all approvals by, all governmental
authorities that may be necessary under any United States Federal or state law
(including the Securities Act, the Exchange Act and state securities and Blue
Sky laws) before the Common Shares issuable upon conversion of Securities may be
lawfully issued and delivered, and thereafter publicly traded (if permissible
under the Securities Act), and qualified or listed as contemplated by clause (2)
(it being understood that for purposes of this Section 1007, the Company shall
not be required to register the Securities or the Common Shares under the
Securities Act); and (2) prior to the time the Securities become convertible,
the Company will cause the Common Shares required to be issued and delivered
upon conversion of Securities, prior to such issuance or delivery, to be quoted
on Nasdaq or, if the Common Shares are not then listed on Nasdaq, cause to be
listed the Common Shares on the United States national securities exchange, if
any, on which Common Shares are listed or quoted at the time of such delivery.
Upon such registration, approval, quotation or listing, if any, as provided in
(1) and (2) above, the Company will deliver to the Trustee and the Conversion
Agent an Officers' Certificate notifying them of such compliance with Section
1007.

SECTION 1008. Limitation on Restricted Payments

     The Company (i) may not, and may not permit any Subsidiary of the Company
to, directly or indirectly, declare or pay any dividend or make any distribution
(including any payment in connection with any merger, amalgamation or
consolidation derived from assets of the Company or any Subsidiary) in respect
of its Capital Stock or to the holders thereof, excluding (a) any dividends or
distributions by the Company payable solely in shares of its Common Stock (other
than Redeemable Stock) or in options, warrants or other rights to acquire its
Common Stock (other than Redeemable Stock), and (b) in the case of a Subsidiary,
dividends or distributions payable (1) to the Company or a Subsidiary and (2) to
minority shareholders of such Subsidiary, provided that at least a pro rata
amount is paid to the Company and/or a Subsidiary, as the case may be, and (ii)
may not, and may not permit any Subsidiary to, directly or indirectly, purchase,
redeem, or otherwise acquire or retire for value (a) any Capital Stock of the
Company or (b) any options, warrants or other rights to acquire shares of
Capital Stock of the Company or any securities convertible or exchangeable into
shares of Capital Stock of the Company (each of clauses (i) and (ii) being a
"Restricted Payment") if: (1) an Event of Default, or an event that with the
passing of time or the giving of notice, or both, would constitute an Event of
Default, shall have occurred and be continuing or would result from such
Restricted Payment, or (2) upon giving effect to such Restricted Payment, the
aggregate of all Restricted Payments from the date of original issuance of the
Securities exceeds the sum of (a) 75% of cumulative Consolidated Net Income (or,
in the case Consolidated Net Income shall be negative, less 100% of such
deficit) of the Company from the date of original issuance of the Securities
through the last day of the last full fiscal quarter ending immediately
preceding such Restricted Payment for which quarterly or annual financial
statements are available (taken as a single accounting period); plus (b) 100% of
the aggregate net cash proceeds received by the Company after the date of
original issuance of the Securities, from contributions of capital or the
issuance and sale (other than to a Subsidiary) of Capital Stock (other than
Redeemable Stock) of the Company, options, warrants or other rights to acquire
Capital Stock (other than Redeemable Stock) of the Company and indebtedness of
the Company that has been converted into or exchanged for Capital Stock (other
than Redeemable Stock and other than by or


                                       52

<PAGE>   63



from a Subsidiary) of the Company after the date of original issuance of the
Securities. Prior to the making of any Restricted Payment, the Company shall
deliver to the Trustee an Officers' Certificate setting forth the computations
by which the determinations required by clause (2) above were made and stating
that no Event of Default, or event that with the passing of time or the giving
of notice, or both, would constitute an Event of Default, has occurred and is
continuing or will result from such Restricted Payment.

     Notwithstanding the foregoing, so long as no Event of Default, or event
that with the passing of time or the giving of notice, or both, would constitute
an Event of Default, shall have occurred and be continuing or would result
therefrom, (i) the Company and any Subsidiary of the Company may pay any
dividend on Capital Stock of any class within 60 days after the declaration
thereof if, on the date when the dividend was declared, the Company or such
Subsidiary could have paid such dividend in accordance with the foregoing
provisions; (ii) the Company may purchase, redeem, acquire or retire any shares
of Capital Stock of the Company solely in exchange for or out of the net
proceeds of the substantially concurrent sale (other than from or to a
Subsidiary or from or to an employee stock ownership plan financed by loans from
the Company or a Subsidiary of the Company) of shares of Capital Stock (other
than Redeemable Stock) of the Company. Any payment made pursuant to clause (i)
or (ii) of this paragraph shall be a Restricted Payment for purposes of
calculating aggregate Restricted Payments pursuant to the preceding paragraph.

SECTION 1009. Limitation on Dividend and Other Payment Restrictions
              Affecting Subsidiaries

     The Company may not, and may not permit any Subsidiary to, directly or
indirectly, create or otherwise cause or suffer to exist or become effective any
encumbrance or restriction on the ability of any Subsidiary of the Company to
pay dividends (in cash or otherwise) or make any other distributions in respect
of its Capital Stock owned by the Company or any other Subsidiary of the
Company. Notwithstanding the foregoing, the Company may, and may permit any
Subsidiary to, suffer to exist any such encumbrance or restriction:

          (1) pursuant to any agreement in effect on the date of original
     issuance of the Securities;

          (2) pursuant to an agreement relating to any indebtedness Incurred by
     a Person (other than a Subsidiary of the Company existing on the date of
     original issuance of the Securities or any Subsidiary carrying on any of
     the businesses of any such Subsidiary) prior to the date on which such
     Person became a Subsidiary of the Company and outstanding on such date and
     not Incurred in anticipation of becoming a Subsidiary, which encumbrance or
     restriction is not applicable to any Person, or the properties or assets of
     any Person, other than the Person so acquired;

          (3) pursuant to an agreement effecting a renewal, extension, refunding
     or refinancing of indebtedness Incurred pursuant to an agreement referred
     to in clause (a) above, provided, however, that the provisions contained in
     such renewal, extension, refunding or refinancing agreement relating to
     such encumbrance or restriction are no more restrictive, taken as a whole,
     than the provisions contained in the agreement the subject thereof, as
     determined in good faith by the Board of Directors and evidenced by a
     resolution of the Board of Directors filed with the Trustee;

          (4) with respect to a Subsidiary of the Company imposed pursuant to an
     agreement which has been entered into for the sale or disposition of all or
     substantially all of the Capital Stock or


                                       53

<PAGE>   64



     assets of such Subsidiary, provided that consummation of such transaction
     would not result in an Event of Default or an event that, with the passing
     of time or the giving of notice or both, would constitute an Event of
     Default, that such restriction terminates if such transaction is closed or
     abandoned and that the closing or abandonment of such transaction occurs
     within one year of the date such agreement was entered into;

          (5) if such encumbrance or restriction is the result of applicable
     corporate law or regulation relating to the payment of dividends or
     distributions.

SECTION 1010. Limitation on Distributions of Assets to Shareholders.

     The Company may not, and may not permit any Subsidiary to, directly or
indirectly, distribute, as a dividend or otherwise, any Capital Stock of a
Subsidiary to shareholders of the Company, unless such Subsidiary shall have
fully and unconditionally guaranteed the payment of principal and interest on
the Notes.

SECTION 1011. Statement By Officers as to Default; Compliance Certificates.

     (a) The Company will deliver to the Trustee, within 120 days after the end
of each fiscal year, and within 60 days after the end of each fiscal quarter

the signers thereof the Company is in default in the performance and observance
of any of the terms, provisions and conditions of Section 801 or Sections 1004
to 1009, inclusive, and if the Company shall be in default, specifying all such
defaults and the nature and status thereof of which they may have knowledge.

     (b) The Company shall deliver to the Trustee, as soon as possible and in
any event within 10 days after the Company becomes aware or should reasonably
become aware of the occurrence of an Event of Default or an event which, with
notice or the lapse of time or both, would constitute an Event of Default, an
Officers' Certificate setting forth the details of such Event of Default or
default, and the action which the Company proposes to take with respect thereto.

     (c) The Company shall deliver to the Trustee within 90 days after the end
of each fiscal year a written statement by the Company's independent public
accountants stating (A) that their audit examination has included a review of
the terms of this Indenture and the Securities as they relate to accounting
matters, and (B) whether, in connection with their audit examination, any event
which, with notice or the lapse of time or both, would constitute an Event of
Default has come to their attention and, if such a default has come to their
attention, specifying the nature and period of the existence thereof.

SECTION 1012. Waiver of Certain Covenants.

     The Company may omit in any particular instance to comply with any covenant
or condition set forth in Section 801 and Sections 1004 to 1009 inclusive, if
before the time for such compliance the Holders of at least a majority in
principal amount of the Outstanding Securities shall, by Act of such Holders,
either waive such compliance in such instance or generally waive compliance with
such covenant or condition, but no such waiver shall extend to or affect such
covenant or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the


                                       54

<PAGE>   65



Company and the duties of the Trustee in respect of any such covenant or
condition shall remain in full force and effect.

SECTION 1013. Indemnification of Judgment Currency.

     The Company shall indemnify the Trustee and any Holder against any loss
incurred by the Trustee or such Holder, as the case may be, as a result of any
judgment or order being given or made for any amount due under this Indenture or
such Security and being expressed and paid in a currency (the "Judgment
Currency") other than Dollars, and as a result of any variation between (i) the
rate of exchange at which the Dollar amount is converted into the Judgment
Currency for the purpose of such judgment or order and (ii) the spot rate of
exchange in The City of New York at which the Trustee or such Holder, as the
case may be, on the date of payment of such judgment or order is able to
purchase Dollars with the amount of the Judgment Currency actually received by
the Trustee or such Holder. The foregoing indemnity shall constitute a separate
and independent obligation of the Company and shall continue in full force and
effect notwithstanding any such judgment or order as aforesaid. The term "spot
rate of exchange" shall include any premiums and costs of exchange payable in
connection with the purchase of, or conversion into, United States dollars as
quoted by The Bank of Nova Scotia at its central foreign exchange desk in its
head office in Toronto at 12:00 noon (Toronto time).

SECTION 1014. Available Information.

     Whether or not the Company is required to be subject to Section 13(a) or
15(d) of the Exchange Act, or any successor provision thereto, the Company shall
file with the Commission the annual reports, quarterly reports and other
documents which the Company would have been required to file with the Commission
pursuant to such Section 13(a) or 15(d) or any successor provision thereto if
the Company were so required, such documents to be filed with the Commission on
or prior to the respective dates (the "Required Filing Dates") by which the
Company would have been required so to file such documents if the Company were
so required. The Company shall also in any event (a) within 15 days of each
Required Filing Date (i) transmit by mail to all Holders, as their names and
addresses appear in the Security Register, without cost to such Holders, and
(ii) furnish to the Trustee, copies of the annual reports, quarterly reports and
other documents which the Company files with the Commission pursuant to such
Section 13(a) or 15(d) or any successor provision thereto or would have been
required to file with the Commission pursuant to such Section 13(a) or 15(d) or
any successor provisions thereto if the Company were required to be subject to
such Sections and (b) if filing such documents by the Company with the
Commission is not permitted under the Exchange Act, promptly upon written
request supply copies of such documents to any prospective Holder.

SECTION 1015. Acquisition of Securities.

     The Company shall not, and shall cause its Affiliates not to, resell or
otherwise dispose of any Securities acquired by them, in the open market or

                            Redemption of Securities

SECTION 1101. Right of Redemption.

     The Securities may be redeemed at the election of the Company, as a whole
in part, upon the occurrence of a Redemption Change of Control in amounts of
$1.00 or any integral multiples of $1.00 at the Redemption Price specified in
the form of Security hereinbefore set forth together with accrued interest to
the Redemption Date. The election of the Company to redeem any Securities
pursuant to Section 1101 shall be evidenced by a Board Resolution.

SECTION 1102. Applicability of Article.

     Redemption of Securities at the election of the Company, as permitted by
any provision of this Indenture, shall be made in accordance with such provision
and this Article.

SECTION 1103.  Notices to Trustee.

     If the Company elects to redeem Securities pursuant to Section 1101, it
shall notify the Trustee of the Redemption Date and the principal amount of
Securities to be redeemed. The Company shall give each notice to the Trustee
provided for in this Section 1103 at least five days prior to the date on which
notice is to be given (or such shorter period as the Trustee may permit), as set
forth in section 1105. Any such notice may be canceled at any time prior to
notice of such redemption being mailed to any Holder and shall thereby be void
and of no effect. In case of any redemption at the election of the Company of
less than all the Securities, the notification to the Trustee shall specify the
principal amount of Securities to be redeemed.

SECTION 1104. Selection by Trustee of Securities to Be Redeemed.

     If less than all the Securities are to be redeemed, the particular
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities not previously
called for redemption, by such method as the Trustee shall deem fair and
appropriate and which may provide for the selection for redemption of portions
(equal to $1.00 or any integral multiple thereof) of the principal amount of
Securities of a denomination larger than $1.00.

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

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

<PAGE>   67



SECTION 1105. 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 set forth:

          (1) the Redemption Date,

          (2) the Redemption Price,

          (3) a brief statement setting forth the Company's right to effect such
     redemption and the Company's basis therefor,

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

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

          (6) the Conversion Price, the date on which the right to convert the
     Securities to be redeemed will terminate and the place or places where such
     Securities may be surrendered for conversion, and

          (7) the place or places where such Securities are to be surrendered
     for payment of the Redemption Price.

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

SECTION 1106. 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 other than any Securities called for redemption
on that date which have been converted prior to the date of such deposit.

     If any Security called for redemption is converted, any money deposited
with the Trustee or with a Paying Agent or so segregated and held in trust for
the redemption of such Security shall (subject to any right of the Holder of
such Security or any Predecessor Security to receive interest as provided in


                                       57

<PAGE>   68



the last paragraph of Section 307) be paid to the Company on Company Request or,
if then held by the Company, shall be discharged from such trust.

SECTION 1107. Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that installments of interest whose
Stated Maturity is on or prior to the Redemption Date shall be payable to the
Holders of such Securities, or one or more Predecessor Securities, registered as
such at the close of business on the 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 shall, until paid, bear interest from the
Redemption Date at the rate provided by the Security and such Security shall
remain convertible into Common Stock until the principal of such Security (or
portion thereof, as the case may be) shall have been paid or duly provided for.

SECTION 1108. Securities Redeemed in Part.

     Any Security which is to be redeemed only in part shall be surrendered at
an office or agency of the Company designated for that purpose pursuant to
Section 1002 (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 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 12

                            Conversion of Securities

SECTION 1201. Conversion Privilege and Conversion Price.

     Subject to and upon compliance with the provisions of this Article, at the
option of the Holder thereof, any Security may be converted into fully paid and
nonassessable Common Shares (calculated as to each conversion to the nearest
1/100th of a share) at the Conversion Price, determined as hereinafter provided,
in effect at the time of conversion. Such conversion right may be exercised at
any time, subject, in the case of the conversion of any Global Security, to any
applicable book-entry procedures of the U.S. Depositary therefor. In case a
Security or portion thereof is called for redemption or is delivered for
purchase, such conversion right in respect of the Security or portion so called
or delivered shall expire at the close of business on the Redemption Date or the
Purchase Date, as the case may be, unless the Company defaults in making the
payment due upon redemption or purchase, as the case may be.



                                       58

<PAGE>   69



     The price at which Common Shares shall be delivered upon conversion (herein
called the "Conversion Price") shall be initially $30.00 per Common Share. The
Conversion Price shall be adjusted in certain instances as provided in this
Article Twelve.

SECTION 1202. Exercise of Conversion Privilege.

     In order to exercise the conversion privilege, the Holder of any Security
to be converted shall (A)(i) surrender such Security, duly endorsed or assigned
to the Company or in blank [(IN THE CASE OF ANY DEFINITIVE SECURITY)] or (ii)
provide appropriate conversion instructions required by the U.S. Depositary then
in effect (in the case of any Global Security), at any office or agency of the
Company maintained for that purpose pursuant to Section 1002, and (B) deliver to
such office or agency a duly signed and completed conversion notice
substantially in the form set forth in Annex A-1, as appropriate, stating that
the Holder elects to convert such Security or, if less than the entire principal
amount thereof is to be converted, the portion thereof to be converted. Each
Security surrendered for conversion (in whole or in part) during the period from
the close of business on any Regular Record Date to the opening of business on
the next succeeding Interest Payment Date (except Securities called for
redemption on a Redemption Date or to be purchased on a Purchase Date during, in
each case, such period) shall be accompanied by payment in same day funds or
other funds acceptable to the Company of an amount equal to the interest payable
on such Interest Payment Date on the principal amount of such Security (or part
thereof, as the case may be) being surrendered for conversion. The interest so
payable on such Interest Payment Date in respect of such Security (or portion
thereof, as the case may be) surrendered for conversion shall be paid to the
Holder of such Security as of such Regular Record Date. Interest payable in
respect of any Security surrendered for conversion on an Interest Payment Date
shall be paid to the Holder of such Security as of the next preceding Regular
Record Date, notwithstanding the exercise of the right of conversion. Except as
provided in this paragraph and subject to the last paragraph of Section 307, no
cash payment or adjustment shall be made upon any conversion on account of, if
the date of conversion is not an Interest Payment Date, any interest accrued
from the Interest Payment Date next preceding the conversion date, in respect of
any Security (or part thereof, as the case may be) surrendered for conversion,
or on account of any dividends on the Common Shares issued upon conversion. The
Company's delivery to the Holder of the number of Common Shares (and cash in
lieu of fractions thereof, as provided in this Indenture) into which a Security
is convertible will be deemed to satisfy the Company's obligation to pay the
principal amount of the Security.

     Securities shall be deemed to have been converted immediately prior to the
close of business on the day of surrender of such Securities for conversion (the
"Conversion Date") in accordance with the foregoing provisions, and at such time
the rights of the holders of such Securities as holders shall cease, and the
Person or Persons entitled to receive the Common Shares issuable upon conversion
shall be treated for all purposes as the record holder or holders of such Common
Shares at such time. As promptly as practicable on or after the Conversion Date,
the Company shall issue and deliver to the Trustee, for delivery to the Holder,
a certificate or certificates for the number of full shares of Common Shares
issuable upon conversion, together with payment in lieu of any fraction of a
share, as provided in Section 1203.

     In the case of any Security which is converted in part only, upon such
conversion the Company shall execute and the Trustee shall authenticate and
deliver to the Holder thereof, at the expense of the Company, a new Security or
Securities of authorized denominations in an aggregate principal amount equal to
the unconverted portion of the principal amount of such Security. A Security may
be converted in part, but only if the principal amount of such Security to be
converted is any integral multiple of $1.00.




                                       59

<PAGE>   70



SECTION 1203. Fractions of Shares.

     No fractional Common Share shall be issued upon conversion of any
Securities. If more than one Security shall be surrendered for conversion at one
time by the same Holder, the number of full shares which shall be issuable upon
conversion thereof shall be computed on the basis of the aggregate principal
amount of the Securities (or specified portions thereof) so surrendered. Instead
of any fractional Common Share which would otherwise be issuable upon conversion
of any Securities (or specified portions thereof), the Company shall calculate
and pay a cash adjustment in respect of such fraction (calculated to the nearest
1/100th of a share) in an amount equal to the same fraction of the current
market price per Common Share (calculated in accordance with Section 1204(8)
below) at the close of business on the day of conversion.

SECTION 1204. Adjustment of Conversion Price.

     The Conversion Price shall be subject to adjustments from time to time as
follows:

     (1) In case the Company shall pay or make a dividend or other distribution
on any class of capital stock of the Company payable in Common Stock, the
Conversion Price in effect at the opening of business on the day following the
date fixed for the determination of stockholders entitled to receive such
dividend or other distribution shall be reduced by multiplying such Conversion
Price by a fraction of which the numerator shall be the number of shares of
Common Stock outstanding at the close of business on the date fixed for such
determination and the denominator shall be the sum of such number of shares and
the total number of shares constituting such dividend or other distribution,
such reduction to become effective immediately after the opening of business on
the day following the date fixed for such determination. For the purposes of
this paragraph (1), the number of shares of Common Stock at any time outstanding
shall not include shares held in the treasury of the Company but shall include
shares issuable in respect of scrip certificates issued in lieu of fractions of
shares of Common Stock. The Company will not pay any dividend or make any
distribution on shares of Common Stock held in the treasury of the Company.

     (2) In case the Company shall issue rights, options or warrants to all
holders of any class of Common Stock entitling them to subscribe for or purchase
shares of any class of Common Stock at a price per share less than the current
market price per share (determined as provided in paragraph (8) of this Section)
of such class of Common Stock on the date fixed for the determination of
shareholders entitled to receive such rights, options or warrants, the
Conversion Price in effect at the opening of business on the day following the
date fixed for such determination shall be reduced by multiplying such
Conversion Price by a fraction of which the numerator shall be the number of
shares of Common Stock outstanding at the close of business on the date fixed
for such determination plus the number of shares of Common Stock which the
aggregate of the offering price of the total number of shares of Common Stock so
offered for subscription or purchase would purchase at such current market price
and the denominator shall be the number of shares of Common Stock outstanding at
the close of business on the date fixed for such determination plus the number
of shares of Common Stock so offered for subscription or purchase, such
reduction to become effective immediately after the opening of business on the
day following the date fixed for such determination. For the purposes of this
paragraph (2), the number of shares of Common Stock at any time outstanding
shall not include shares held in the treasury of the Company but shall include
shares issuable in respect of scrip certificates issued in lieu of fractions of
shares of Common Stock. The Company will not issue any rights, options or
warrants in respect of shares of Common Stock held in the treasury of the
Company.




                                       60

<PAGE>   71



     (3) In case outstanding shares of any class of Common Stock shall be
subdivided into a greater number of shares of such class of Common Stock, and,
conversely, in case outstanding shares of any class of Common Stock shall each
be combined into a smaller number of shares of such class of Common Stock, the
Conversion Price in effect at the opening of business on the day following the
day upon which such subdivision or combination becomes effective shall be
adjusted by the Company so that the same shall equal the price determined by
multiplying the Conversion Price in effect immediately prior to the
effectiveness of the Conversion Price adjustment contemplated by this
subparagraph (3) by a fraction of which the numerator shall be the number of
shares of Common Stock outstanding immediately prior to such subdivision or
combination and the denominator shall be the number of shares of Common Stock
outstanding immediately after giving effect to such subdivision or combination,
such adjustment to become effective immediately after the opening of business on
the day following the day upon which such subdivision or combination becomes
effective.

     (4) In case the Company shall, by dividend or otherwise, distribute to all
holders of its Common Stock evidences of its indebtedness, shares of any class
of capital stock, or other property (including securities, but excluding (i) any
rights, options or warrants referred to in paragraph (2) of this Section, (ii)
any dividend or distribution paid exclusively in cash, (iii) any dividend or
distribution referred to in paragraph (1) of this Section and (iv) any merger or
consolidation to which Section 1211 applies), the Conversion Price shall be
adjusted so that the same shall equal the price determined by multiplying the
Conversion Price in effect immediately prior to the close of business on the
date fixed for the determination of stockholders entitled to receive such
distribution by a fraction of which (i) the numerator shall be the current
market price per share (determined as provided in paragraph (8) of this Section)
of the Common Stock on the third Trading Day prior to the date fixed for such
determination (the "Reference Date") less the then fair market value (as
determined by the Board of Directors, whose determination shall be conclusive
and described in a Board Resolution) on the Reference Date of the portion of the
assets, shares or evidences of indebtedness so distributed applicable to one
share of Common Stock and the denominator shall be the current market price per
share of Common Stock on the Reference Date, such adjustment to become effective
immediately prior to the opening of business on the day following the Reference
Date.

     (5) In case the Company shall, by dividend or otherwise, distribute to all
holders of any class of its Common Stock cash (excluding any cash that is
distributed upon a merger or consolidation to which Section 1211 applies or as
part of a distribution referred to in paragraph (4) of this Section) in an
aggregate amount that, combined together with (I) the aggregate amount of any
other cash distributions to all holders of any class of its Common Stock made
exclusively in cash within the 12 months preceding the date of payment of such
distribution and in respect of which no adjustment pursuant to this paragraph
(5) has been made and (II) the aggregate of any cash plus the fair market value
(as determined by the Board of Directors, whose determination shall be
conclusive and described in a Board Resolution) of consideration payable in
respect of any tender offer by the Company or any of its subsidiaries for all or
any portion of any class of Common Stock concluded within the 12 months
preceding the date of payment of such distribution and in respect of which no
adjustment pursuant to paragraph (6) of this Section has been made, exceeds
30.0% of the product of the current market price per share of Common Stock on
the date for the determination of holders of Common Stock entitled to receive
such distribution times the number of shares of all classes of Common Stock
outstanding on such date, then, and in each such case, immediately after the
close of business on such date for determination, the Conversion Price shall be
adjusted so that the same shall equal the price determined by multiplying the
Conversion Price in effect immediately prior to the close of business on the
date fixed for determination of the stockholders entitled to receive such


                                       61

<PAGE>   72



distribution by a fraction (i) the numerator of which shall be equal to the
current market price per share (determined as provided in paragraph (8) of this
Section) of the Common Stock on the date fixed for such determination less an
amount equal to the quotient of (x) the excess of such combined amount in (I)
and (II) above over such 30.0% and (y) the number of shares of all classes of
Common Stock outstanding on such date for determination and (ii) the denominator
of which shall be equal to the current market price per share (determined as
provided in paragraph (8) of this Section) of the Common Stock on such date for
determination.

     (6) In case a tender or exchange offer (other than an odd-lot offer) made
by the Company or any Subsidiary for all or any portion of any class of Common
Stock shall expire and such tender or exchange offer shall involve the payment
by the Company or such Subsidiary of consideration per share of such class of
Common Stock having a fair market value (as determined by the Board of
Directors, whose determination shall be conclusive and described in a Board
Resolution) at the last time (the "Expiration Time") tenders or exchanges may be
made pursuant to such tender or exchange offer (as it shall have been amended)
that exceeds 120% of the current market price per share (determined as provided
in paragraph (8) of this Section) of such class of Common Stock as of the
Trading Day next succeeding the Expiration Time, the Conversion Price shall be
reduced so that the same shall equal the price determined by multiplying the
Conversion Price in effect immediately prior to the effectiveness of the
Conversion Price reduction contemplated by this subparagraph (6) by a fraction
of which the numerator shall be the sum of the product of the number of shares
of each class of Common Stock outstanding (including any tendered or exchanged
shares) at the Expiration Time multiplied by the respective current market price
per share (determined as provided in paragraph (8) of this Section) of each such
class of Common Stock on the Trading Day next succeeding the Expiration Time and
the denominator shall be the sum of (x) the fair market value (determined as
aforesaid) of the aggregate consideration payable to stockholders based on the
acceptance (up to any maximum specified in the terms of the tender or exchange
offer) of all shares validly tendered or exchanged and not withdrawn as of the
Expiration Time (the shares deemed so accepted, up to any such maximum, being
referred to as the "Purchased Shares") and (y) the sum of the products of the
number of shares of each class of Common Stock outstanding (less any Purchased
Shares) at the Expiration Time and the respective current market price per share
(determined as provided in paragraph (8) of this Section) of each such class of
Common Stock on the Trading Day next succeeding the Expiration Time, such
reduction to become effective immediately prior to the opening of business on
the day following the Expiration Time.

     (7) The reclassification of any class of Common Stock into securities
including other than Common Stock (other than any reclassification upon a
consolidation or merger to which Section 1211 applies) shall be deemed to
involve (a) a distribution of such securities other than Common Stock to all
holders of Common Stock (and the effective date of such reclassification shall
be deemed to be "the date fixed for the determination of stockholders entitled
to receive such distribution" and "the date fixed for such determination" within
the meaning of paragraph (4) of this Section), and (b) a subdivision or
combination, as the case may be, of the number of shares of such class of Common
Stock outstanding immediately prior to such reclassification into the number of
shares of Common Stock outstanding immediately thereafter (and the effective
date of such reclassification shall be deemed to be "the day upon which such
subdivision becomes effective" or "the day upon which such combination becomes
effective", as the case may be, and "the day upon which such subdivision or
combination becomes effective" within the meaning of paragraph (3) of this
Section).




                                       62

<PAGE>   73



     (8) For the purpose of any computation under paragraphs (2), (4), (5) or
(6) of this Section 1204, the current market price per share of a class of
Common Stock on any date shall be calculated by the Company and be deemed to be
the average of the daily Closing Prices Per Share of such class for the five
consecutive Trading Days selected by the Company commencing not more than 10
Trading Days before, and ending not later than, the earlier of the day in
question and the day before the "ex" date with respect to the issuance or
distribution requiring such computation. For purposes of this paragraph, the
term "ex date", when used with respect to any issuance or distribution, means
the first date on which such class of Common Stock trades regular way in the
applicable securities market or on the applicable securities exchange without
the right to receive such issuance or distribution.

     (9) No adjustment in the Conversion Price shall be required unless such
adjustment (plus any adjustments not previously made by reason of this paragraph
(9)) would require an increase or decrease of at least one percent in such
price; provided, however, that any adjustments which by reason of this paragraph
(9) are not required to be made shall be carried forward and taken into account
in any subsequent adjustment. All calculations under this Article shall be made
to the nearest cent or to the nearest one-hundredth of a share, as the case may
be.

     (10) The Company may make such reductions in the Conversion Price, for the
remaining term of the Securities or any shorter term, in addition to those
required by paragraphs (1), (2), (3), (4), (5) and (6) of this Section 1204, as
it considers to be advisable in order to avoid or diminish any income tax to any
holders of Common Shares resulting from any dividend or distribution of stock or
issuance of rights or warrants to purchase or subscribe for stock or from any
event treated as such for income tax purposes.

SECTION 1205. Notice of Adjustments of Conversion Price.

     Whenever the Conversion Price is adjusted as herein provided:

          (1) the Company shall compute the adjusted Conversion Price in
     accordance with Section 1204 and shall prepare a certificate signed by the
     Treasurer of the Company setting forth the adjusted Conversion Price and
     showing in reasonable detail the facts upon which such adjustment is based,
     and such certificate shall promptly be filed with the Trustee and with each
     Conversion Agent; and

          (2) a notice stating that the Conversion Price has been adjusted and
     setting forth the adjusted Conversion Price shall forthwith be required,
     and as soon as practicable after it is required, such notice shall be
     provided by the Company to all holders in accordance with Section 106.

Neither the Trustee nor any Conversion Agent shall be under any duty or
responsibility with respect to any such certificate or the information and
calculations contained therein, except to exhibit the same to any Holder of
Securities desiring inspection thereof at its office during normal business
hours.

SECTION 1206. Notice of Certain Corporate Action.

<PAGE>   74



          (a) the Company shall declare a dividend (or any other distribution)
     on any class of its Common Stock payable (i) otherwise than exclusively in
     cash or (ii) exclusively in cash in an amount that would require any
     adjustment pursuant to Section 1204; or

          (b) the Company shall authorize the granting to all holders of any
     class of its Common Stock of rights, options or warrants to subscribe for
     or purchase any shares of Capital Stock of any class or of any other

          (c) of any reclassification of any class of Common Stock of the
     Company (other than a subdivision or combination of its outstanding shares
     of Common Stock), or of any consolidation or merger to which the Company is
     a party and for which approval of any stockholders of the Company is

     assets of the Company; or

          (d) of the voluntary or involuntary dissolution, liquidation or
     winding up of the Company; or

          (e) the Company or any Subsidiary shall commence a tender offer for
     all or a portion of any class of the Company's outstanding shares of Common
     Stock that would require an adjustment of the Conversion Price pursuant to
     paragraph (6) of Section 1204 (or shall amend any such tender offer);

then the Company shall cause to be filed at each office or agency maintained for
the purpose of conversion of Securities pursuant to Section 1002, and shall
cause to be provided to all holders in accordance with Section 106, at least 20
days (or 10 days in any case specified in clause (a) or (b) above) prior to the
applicable record, expiration or effective date hereinafter specified, a notice
stating (x) the date on which a record is to be taken for the purpose of such
dividend, distribution, rights, options or warrants, or, if a record is not to
be taken, the date as of which the holders of Common Stock of record to be
entitled to such dividend, distribution, rights, options or warrants are to be
determined, (y) the date on which the right to make tenders under such tender
offer expires or (z) the date on which such reclassification, consolidation,
merger, share exchange, conveyance, transfer, sale, lease, dissolution,
liquidation or winding up is expected to become effective, and the date as of
which it is expected that holders of Common Stock of record shall be entitled to
exchange their shares of Common Stock for securities, cash or other property
deliverable upon such reclassification, consolidation, merger, share exchange,
conveyance, transfer, sale, lease, dissolution, liquidation or winding up. If at
the time the Trustee shall not be the conversion agent, a copy of such notice
and any notice referred to in the following paragraph shall also forthwith be
filed by the Company with the Trustee.

SECTION 1207. Company to Reserve Common Shares.

     The Company shall at all times reserve and keep available, free from
preemptive rights, out of its authorized but unissued Common Shares, for the

                                       64

<PAGE>   75



     The Company will pay any and all taxes and duties that may be payable in
respect of the issue or delivery of shares of Common Shares on conversion of
Securities pursuant hereto. The Company shall not, however, be required to pay
any tax or duty which may be payable in respect of any transfer involved in the
issue and delivery of shares of Common Shares in a name other than that of the
Holder of the Security or Securities to be converted, and no such issue or
delivery shall be made unless and until the Person requesting such issue has
paid to the Company the amount of any such tax or duty, or has established to
the satisfaction of the Company that such tax or duty has been paid.

SECTION 1209. Covenant as to Common Shares.

     The Company agrees that all Common Shares which may be delivered upon
conversion of Securities, upon such delivery, will have been duly authorized and
validly issued and will be fully paid and nonassessable and free of any liens,
charges or adverse claims.

SECTION 1210. Cancellation of Converted Securities.

     All Securities delivered for conversion shall be delivered to the Trustee
or its agent to be canceled by or at the direction of the Trustee, which shall
dispose of the same as provided in Section 308.

SECTION 1211. Provision in Case of Amalgamation, Consolidation, Merger or
              Sale of Assets.

     In case of any amalgamation or consolidation of the Company with, or merger
of the Company into, any other Person, any merger of another Person into the
Company (other than a merger which does not result in any reclassification,
conversion, exchange or cancellation of outstanding Common Shares of the
Company) or any sale or transfer of all or substantially all of the assets of
the Company, the Person formed by such amalgamation or consolidation or
resulting from such merger or which acquires such assets, as the case may be,
shall execute and deliver to the Trustee a supplemental indenture providing that
the Holder of each Security then Outstanding shall have the right thereafter,
during the period such Security shall be convertible as specified in Section
1201, to convert such Security only into the kind and amount of securities, cash
and other property receivable upon such amalgamation, consolidation, merger,
sale or transfer by a holder of the number of shares of Common Shares of the
Company into which such Security might have been converted immediately prior to
such amalgamation, consolidation, merger, sale or transfer, [SUBJECT TO ANY
REQUIREMENTS NECESSARY TO ENSURE THAT THE SECURITIES WILL NOT BE SUBJECT TO
CANADIAN WITHHOLDING TAX AS A RESULT OF SUCH EVENT,] and assuming such holder of
Common Shares of the Company (i) is not a Person with which the Company
consolidated or amalgamated or into which the Company merged or which merged
into the Company or to which such sale or transfer was made, as the case may be
("Constituent Person"), or an Affiliate of a Constituent Person and (ii) failed
to exercise his rights of election, if any, as to the kind or amount of
securities, cash and other property receivable upon such consolidation,
amalgamation, merger, sale or transfer (provided that if the kind or amount of
securities, cash and other property receivable upon such consolidation,
amalgamation, merger, sale or transfer is not the same for each Common Share of
the Company held immediately prior to such consolidation, amalgamation, merger,
sale or transfer by Persons other than a Constituent Person or an Affiliate
thereof and in respect of which such rights of election shall not have been
exercised ("Non-electing Share"), then for the purpose of this Section 1211 the
kind and amount of securities, cash and other property receivable upon such
amalgamation, consolidation, merger, sale or transfer by the holders of each
Non-electing Share shall be deemed to be the kind and amount so receivable per
share by a plurality of the Non-electing Shares) [SUBJECT, HOWEVER, TO ANY
REQUIREMENTS NECESSARY TO ENSURE THAT


                                       65

<PAGE>   76



THE SECURITIES WILL BE AND WILL REMAIN EXEMPT FROM CANADIAN WITHHOLDING TAX
INCLUDING, WITHOUT LIMITATION, THE REQUIREMENT IN EFFECT ON THE DATE HEREOF THAT
A HOLDER OF SECURITIES SHALL NOT BE ENTITLED TO RECEIVE SHARES, OTHER SECURITIES
OR PROPERTY, OTHER THAN SHARES THAT ARE "PRESCRIBED SECURITIES" AS DEFINED IN
REGULATION 6208 TO THE INCOME TAX ACT (CANADA), IN THE EVENT THAT ANY SUCH
AMALGAMATION, CONSOLIDATION, MERGER OR TRANSFER OCCURS ON OR PRIOR TO FIVE YEARS
AFTER THE DATE OF ORIGINAL ISSUE OF THE SECURITIES]. Such supplemental indenture
shall provide for adjustments which, for events subsequent to the effective date
of such supplemental indenture, shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article. The above
provisions of this Section 1211 shall similarly apply to successive
consolidations, mergers, sales or transfers. Notice of the execution of such a
supplemental indenture shall be given by the Company to the Holder of each
Security as provided in Section 106 promptly upon such execution.

SECTION 1212. Responsibility of Trustee.

     Neither the Trustee nor any authenticating agent nor any Conversion Agent
shall at any time be under any duty or responsibility to any Holder of
Securities to determine whether any facts exist which may require any adjustment
of the Conversion Price, or with respect to the nature or extent of any such
adjustment when made, or with respect to the method employed, or herein or in
any supplemental indenture provided to be employed, in making the same. Neither
the Trustee nor any authenticating agent nor any Conversion Agent shall be
accountable with respect to the validity or value (or the kind or amount) of any
Common Shares, or of any securities or property, which may at any time be issued
or delivered upon the conversion of any Securities; and neither the Trustee nor
any authenticating agent nor any Conversion Agent makes any representation with
respect thereto. Neither the Trustee nor any authenticating agent nor any
Conversion Agent shall be responsible for any failure of the Company to issue,
transfer or deliver any Common Shares or stock certificates or other securities
or property or cash upon the surrender of any Securities for the purpose of
conversion or to comply with any of the covenants of the Company contained in
this Article.

                                   ARTICLE 13

                           Subordination of Securities

SECTION 1301. Securities Subordinated to Senior Indebtedness.

     All Securities issued under this Indenture shall be issued subject to the
following provisions and each Holder of any Security whether upon original issue
or upon transfer or assignment thereof accepts and agrees to be bound by such
provisions.

     All Securities issued hereunder shall, to the extent and in the manner
hereinafter set forth, be subordinated and subject in right of payment to the
prior payment in full of all Senior Indebtedness. "Senior Indebtedness" means
(i) the principal, premium, if any, and interest in respect of indebtedness of
the Company for money borrowed, or evidenced by securities, debentures, bonds or
other similar instruments issued by the Company, or pursuant to any obligation
of the Company for the reimbursement on any letter of credit, bankers
acceptance, security purchase facility or similar credit transaction pursuant to
a credit facility with or agented by, a Bank, including pursuant to the Exit
Facility and the Credit Agreement, (ii) any amendments, renewals, extensions,
refinancings, replacements or refundings of any obligations of the type referred
to in clause (i) above (regardless of whether such amendment, renewal,
extension, refinancing, replacement or refunding is pursuant to a credit
facility with or agented by a Bank), (iii) all obligations of the type referred
to in clauses (i) and (ii) above of other persons


                                       66

<PAGE>   77



for the payment of which the Company is responsible or liable as obligor,
guarantor or otherwise, and (iv) all obligations of the type referred to in
clauses (i) through (iii) above of other persons secured by any lien on any
property or asset of the Company (whether or not such obligation is assumed by
the Company), except for any such indebtedness or other obligation that is by
its terms subordinated to or pari passu with the Securities.

SECTION 1302. No Payments in Certain Circumstances;
              Payment Over of Proceeds Upon Dissolution, Etc.

     No payment on account of principal of, premium, if any, or interest on, or
redemption or purchase of, the Securities shall be made if, at the time of such
payment or immediately after giving effect thereto: (i) there shall exist a
default in the payment of principal of, premium, if any, sinking funds or
interest (including a default under any purchase or redemption obligations) with
respect to any Senior Indebtedness, or (ii) there shall have occurred an event
of default (other than a default in the payment of principal, premium, if any,
sinking funds or interest) with respect to any Senior Indebtedness, as defined
therein or in the instrument under which the same is outstanding, permitting the
holders thereof to accelerate the maturity thereof and written notice of such
occurrence shall have been given to the Company and to the Trustee under this
Indenture by the holder or holders of such Senior Indebtedness and such event of
default shall not have been cured or waived or shall not have ceased to exist.
Notwithstanding the foregoing, the Company may make, and the Trustee may receive
and shall apply, any payment in respect of the Securities (for principal,
premium, if any, or interest or purchase) if such payment was made prior to the
occurrence of any of the contingencies specified in clauses (i) and (ii) above.

     Upon (i) any acceleration of the principal amount due on the Securities or
(ii) any payment or distribution of assets of the Company of any kind or
character, whether in cash, property or securities, to creditors upon any
dissolution or winding up or total or partial liquidation or reorganization of
the Company, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all principal of, premium, if any, sinking
fund and interest due or to become due upon all Senior Indebtedness shall first
be paid in full, or payment thereof provided for in money or money's worth in
accordance with its terms, before any payment is made on account of the
principal of, or interest on, or purchase of, the indebtedness evidenced by the
Securities, and upon any such dissolution or winding up or liquidation or
reorganization any payment or distribution of assets of the Company of any kind
or character, whether in cash, property or securities, to which the holders of
the Securities or the Trustee under this Indenture would be entitled, except for
the provisions hereof, shall be paid by the Company or by any receiver, trustee
in bankruptcy, liquidating trustee, agent or other Person making such payment or
distribution, or by the holders of the Securities or by the Trustee under this
Indenture if received by them or it, as the case may be, directly to the holders
of Senior Indebtedness (pro rata to each such holder on the basis of the
respective amounts of Senior Indebtedness held by such holder) or their
representatives, to the extent necessary to pay all Senior Indebtedness in full,
in money or money's worth, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Indebtedness, before any payment or
distribution is made to the holders of the Securities or to the Trustee under
this Indenture.

     If any default or event described in the first paragraph of this Section
1302 shall have occurred, any payment or distribution of assets of the Company
of any kind or character, whether in cash, property or securities, received by
the Trustee or the holders of the Securities before all Senior Indebtedness is
paid in full or provision made for such payment, in accordance with its terms
shall be held in trust for the benefit of, and shall be paid over or delivered
to, the holders of such Senior Indebtedness or their


                                       67

<PAGE>   78



representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing any of such Senior
Indebtedness have been issued, as their respective interests may appear, for
application to the payment of all Senior Indebtedness remaining unpaid to the
extent necessary to pay all such Senior Indebtedness in full in accordance with
its terms, after giving effect to any concurrent payment or distribution to or
for the holders of such Senior Indebtedness.

     Subject to the payment in full of all Senior Indebtedness, the holders of
the Securities (together with the holders of any other indebtedness of the
Company which is subordinated in right of payment to the payment in full of all
Senior Indebtedness, which is not subordinated in right of payment to the
Securities and which by its terms grants such right of subrogation to the
holders thereof) shall be subrogated to the rights of the holders of Senior
Indebtedness to receive payments or distributions of assets of the Company made
on the Senior Indebtedness until the principal of, premium, if any, and interest
on, or purchase of, the Securities shall be paid in full; and, for the purposes
of such subrogation, no payments or distributions to the holders of Senior
Indebtedness of any cash, property or securities to which the holders of the
Securities or the Trustee would be entitled except for the provisions of this
Article, and no payment over pursuant to the provisions of this Article to the
holders of Senior Indebtedness by the holders of the Securities or the Trustee,
shall, as between the Company, its creditors other than the holders of Senior
Indebtedness, and the holders of Securities, be deemed to be a payment by the
Company to the holders of or on account of Senior Indebtedness, it being
understood that the provisions of this Article are and are intended solely for
the purpose of defining the relative rights of the holders of the Securities, on
the one hand, and the holders of Senior Indebtedness, on the other hand.


SECTION 1303. Notice to Trustee of Specified Events;
              Reliance on Certificate of Liquidating Agent.

     The Company shall give prompt written notice to the Trustee of any
insolvency or bankruptcy proceeding in respect of the Company, of any
proceedings for voluntary liquidation, dissolution or other winding up of the
Company (whether or not involving insolvency or bankruptcy), of the declaration
of any Security as due and payable before its expressed maturity, and of any
event which pursuant to Section 1302 would prevent payment by the Company on
account of the principal, or interest on, or purchase of, the Securities. The
Trustee, subject to the provisions of Section 601, shall be entitled to assume
that no such event has occurred unless the Company, or a holder of Senior
Indebtedness, or any trustee therefor, has given such notice.

     Upon any distribution of assets of the Company or payment by or on behalf
of the Company referred to in this Article, the Trustee and the holders of the
Securities shall be entitled to rely upon any order or decree of a court of
competent jurisdiction in which any proceedings of the nature referred to in
Section 1302 are pending, and the Trustee, subject to the provisions of Section
601, and the holders of the Securities shall be entitled to rely upon a
certificate of the liquidating trustee or agent or other Person making any
distribution to the Trustee or to the holders of the Securities for the purpose
of ascertaining the Persons entitled to participate in such distribution, the
holders of the Senior Indebtedness and other indebtedness of the Company, the
amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article. In the event
that the Trustee determines, in good faith, that further evidence is required
with respect to the right of any Person as a holder of Senior Indebtedness to
participate in any payment or distribution pursuant to this Article, the Trustee
may request such Person to furnish evidence to the reasonable satisfaction of
the Trustee as to the


                                       68

<PAGE>   79



amount of Senior Indebtedness held by such Person, as to the extent to which
such Person is entitled to participate in such payment or distribution, and as
to other facts pertinent to the rights of such Person under this Article, and if
such evidence is not furnished, the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such
payment.

     The Trustee shall be entitled to rely on the delivery to it of a written
notice by a Person representing itself to be a holder of Senior Indebtedness (or
a trustee on behalf of such holder) to establish that such notice has been given
by a holder of Senior Indebtedness or a trustee on behalf of any such holder or
holders. In the event that the Trustee determines in good faith that further
evidence is required with respect to the right of any Person as a holder of
Senior Indebtedness to participate in any payment or distribution pursuant to
this Article Thirteen, the Trustee may request such Person to furnish evidence
to the reasonable satisfaction of the Trustee as to the amount of Senior
Indebtedness held by such Person, the extent to which such Person is entitled to
participate in such payment or distribution and any other facts pertinent to the
rights of such Person under this Article Thirteen and, if such evidence is not
furnished, the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment.

SECTION 1304. Trustee to Effectuate Subordination.

     The Holder of each Security by its acceptance thereof authorizes and
directs the Trustee on its behalf to take such action as may be necessary or
appropriate to acknowledge or effectuate the subordination as provided in this
Article and appoints the Trustee as attorney-in-fact for any and all such
purposes.

SECTION 1305. Trustee Not Charged with Knowledge of Prohibition.

     Notwithstanding the provisions of this Article or any other provision of
this Indenture, but subject to the provisions of Section 601 as between the
holders of Securities and the Trustee, neither the Trustee nor any Paying Agent
shall be charged with knowledge of any facts which would prohibit the making of
any payment of moneys to or by the Trustee or any such Paying Agent, unless and
until the Trustee or such Paying Agent shall have received written notice
thereof at its Corporate Trust Office from the Company or any holder of Senior
Indebtedness or the trustee or representative of any holder of such Senior
Indebtedness on his behalf; and, prior to the receipt of any such written
notice, the Trustee and any such Paying Agent shall be entitled to assume that
no such facts exist. If the Trustee or Paying Agent, as the case may be, shall
not have received, at least three Business Days prior to the date upon which by
the terms hereof any such moneys may become payable for any purpose (including,
without limitation, the payment of the principal of, premium, if any, or the
interest on any Security) with respect to such moneys, the notice provided for
in this Section, then, anything herein contained to the contrary
notwithstanding, the Trustee and such Paying Agent, as the case may be, shall
have full power and authority to receive such moneys and to apply the same to
the purpose for which they were received and shall not be affected by any notice
to the contrary which may be received by it within three Business Days prior to
such date.

SECTION 1306. Trustee Not Fiduciary for Holders of Senior Indebtedness.

     The Trustee shall not be deemed to owe any fiduciary duty to the holders of
Senior Indebtedness and shall not be liable to any such holders if it shall in
good faith mistakenly pay over or distribute to


                                       69

<PAGE>   80



holders of Securities or to the Company or to any other Person cash, property or
securities to which any holders of Senior Indebtedness shall be entitled by
virtue of this Article or otherwise.

     With respect to the holders of Senior Indebtedness, the Trustee undertakes
to perform or to observe only such of its covenants or obligations as are
specifically set forth in this Article and no implied covenants or obligations
with respect to holders of Senior Indebtedness shall be read into this Indenture
against the Trustee.

SECTION 1307. Rights of Trustee as Holder of Senior Indebtedness;
              Preservation of Trustee's Rights.

     The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article with respect to any Senior Indebtedness which may at
any time be held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of
its rights as such holder.

     Nothing in this Article shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 607.

SECTION 1308. Article Applicable to Paying Agents.

     In case at any time any Paying Agent other than the Trustee shall have been
appointed by the Company and be then acting hereunder, the term "Trustee" as
used in this Article shall in such case (unless the context otherwise requires)
be construed as extending to and including such Paying Agent within its meaning
as fully for all intents and purposes as if such Paying Agent were named in this
Article in addition to or in place of the Trustee; provided, however, that
Sections 1305, 1306 and 1307 shall not apply to the Company or any Affiliate of
the Company if it or such Affiliate acts as Paying Agent.

SECTION 1309. Certain Conversions Deemed Payment.

     For the purposes of this Article only, (1) the issuance and delivery of
junior securities upon conversion of Securities in accordance with Article
Twelve shall not be deemed to constitute a payment or distribution on account of
the principal of or premium or interest on Securities or on account of the
purchase or other acquisition of Securities, and (2) the payment, issuance or
delivery of cash, property or securities (other than junior securities) upon
conversion of a Security shall be deemed to constitute payment on account of the
principal of such Security. For the purposes of this Section, the term "junior
securities" means Common Shares and any other cash, property or securities into
which the Securities are convertible pursuant to Article Twelve. Nothing
contained in this Article or elsewhere in this Indenture or in the Securities is
intended to or shall impair, as among the Company, its creditors other than
holders of Senior Indebtedness and the holders of the Securities, the right,
which is absolute and unconditional, of the Holder of any Security to convert
such Security in accordance with Article Twelve.

                                Change of Control

SECTION 1401. Change of Control.

     (a) Within 30 days of the occurrence of a Change of Control, the Company
will be required to mail an Offer with respect to an Offer to Purchase all
Outstanding Securities at the Purchase Price thereof plus accrued interest to
the Purchase Date (provided, however, that installments of interest whose Stated
Maturity is on or prior to the Purchase Date shall be payable to the Holders of
such Securities, or one or more Predecessor Securities, registered as such at
the close of business on the relevant Record Dates according to their terms and
the provisions of Section 307). Each Holder shall be entitled to tender all or
any portion of the Securities owned by such Holder pursuant to the Offer to
Purchase, subject to the requirement that any portion of a Security tendered
must be tendered in an integral multiple of $1.00 principal amount.

     (b) The Company and the Trustee shall perform their respective obligations
specified in the Offer for an Offer to Purchase. Prior to the Purchase Date, the
Company shall (i) accept for payment Securities or portions thereof tendered
pursuant to the Offer, (ii) deposit with the Paying Agent (or, if the Company is
acting as its own Paying Agent, segregate and hold in trust as provided in
Section 1003) money sufficient to pay the purchase price of all Securities or
portions thereof so accepted and (iii) deliver or cause to be delivered to the
Trustee all Securities so accepted together with an Officers' Certificate
stating the Securities or portions thereof accepted for payment by the Company.
The Paying Agent shall promptly mail or deliver to Holders of Securities so
accepted payment in an amount equal to the purchase price, and the Trustee shall
promptly authenticate and mail or deliver to such Holders a new Security or
Securities equal in principal amount to any unpurchased portion of the Security
surrendered as requested by the Holder. Any Security not accepted for payment
shall be promptly mailed or delivered by the Company to the Holder thereof. The
Company shall publicly announce the results of the Offer on or as soon as
practicable after the Purchase Date.

     (c) Any Offer to Purchase shall be governed by and effected in accordance
with the Offer for such Offer to Purchase.

SECTION 1402. Certain Definitions.

     For purposes of this Article 14,

     (1) "beneficial owner" shall be determined in accordance with Rule 13d-3,
as in effect on the date of the original execution of this Indenture,
promulgated by the Commission pursuant to the Exchange Act;

     (2) a "Change of Control" shall be deemed to have occurred (unless the
Company is discharged from its obligations with respect to the Securities in
accordance with Article 4) at the time, after the original issuance of the
Securities, of: (i) an event or series of events by which any Person or other
entity or Group of Persons (other than a Permitted Holder) (such Person or group
of Persons, an "Acquiror") shall, as a result of (A) a tender or exchange offer,
open market purchases or privately negotiated purchases, or (B) a merger,
consolidation, amalgamation or otherwise, have become the


                                       71

<PAGE>   82



beneficial owner of more than 50% of the aggregate voting power of all classes
of Voting Stock of the Company; or (ii) the Company is amalgamated or
consolidated with or merged into another corporation with the effect that
immediately after such transaction the shareholders of the Company immediately
prior to such transaction beneficially own less than a majority of the voting
power of all classes of Voting Stock of the Person surviving such transaction,
and the Acquiror beneficially owns more than a majority of the voting power of

         On September 21, 1999, the United States Bankruptcy Court for the
District of Delaware (the "Bankruptcy Court") (i) approved the Disclosure
Statement (the "Disclosure Statement") with Respect to the First Amended Joint
Plan of Reorganization (the "Plan") of Philip Services Corp. ("PSC"), Philip
Services (Delaware), Inc. ("PSI") and certain of their affiliates (the
"Affiliate Debtors"), debtors and debtors-in-possession in the above-captioned
cases (collectively, the "Debtors"), and (ii) authorized the Debtors to solicit
votes with regard to the approval or rejection of the Plan. Capitalized terms in
these instructions which are not defined have the meanings set forth in the
Plan.

                     INSTRUCTIONS FOR COMPLETING THE BALLOT

         THIS BALLOT DOES NOT CONSTITUTE AND SHALL NOT BE DEEMED TO CONSTITUTE
(A) A PROOF OF CLAIM OR (B) AN ADMISSION BY THE DEBTORS OF THE NATURE, VALIDITY,
OR AMOUNT OF ANY CLAIM. THIS BALLOT IS NOT A LETTER OF TRANSMITTAL AND MAY NOT
BE USED FOR ANY OTHER PURPOSE THAN TO CAST VOTES TO ACCEPT OR REJECT THE PLAN.
DO NOT ENCLOSE NOTES OR SECURITIES WITH YOUR COMPLETED BALLOT.

         1. This Ballot is submitted to you to solicit your vote to accept or
reject the Plan. Please indicate your vote by marking an "x" in the appropriate
box on the face of the Ballot.

         2. In the event that Class 7 votes to accept the Plan, Qualifying Class
7 Creditors may elect to forgo their Pro Rata distribution of New Unsecured PIK
Notes for New Unsecured Convertible Notes (See Article III.C.2(d) of the Plan,
entitled "Other Provisions Applicable to Class 7") subject to certain terms and
limitations set forth in the Plan. Qualifying Class 7 Creditors consist of
holders of Impaired Unsecured Claims that, as of the Voting Deadline, are
Allowed Impaired Unsecured Claims in a liquidated amount, excluding by agreement
CIBC and its affiliates. Qualifying Class 7 Creditors electing New Unsecured
Convertible Notes shall receive, in exchange for every $1.00 in face amount of
New Unsecured PIK Notes that such Qualifying Class 7 Creditor would have
received under the Plan, $1.50 in fact amount of New Unsecured Convertible
Notes. PLEASE INDICATE YOUR ELECTION BY MARKING AN "X" IN THE APPROPRIATE BOX ON
THE FACE OF THE BALLOT. HOLDERS OF OLD DEBENTURES (AS DEFINED IN THE PLAN) THAT
(A) DO NOT MAKE AN AFFIRMATIVE ELECTION OR SELECT BOTH PAYMENT OPTIONS OR (B) DO
NOT VOTE, WILL BE DEEMED TO HAVE ELECTED TO RECEIVE THE NEW CONVERTIBLE NOTES.
ALL OTHER QUALIFYING CLASS 7 CREDITORS WHO (A) FAIL TO MAKE AN AFFIRMATIVE
ELECTION OR THAT SELECT PAYMENT BY BOTH OPTIONS OR (B) DO NOT VOTE, WILL DE
DEEMED TO HAVE ELECTED PAYMENT BY NEW UNSECURED PIK NOTES.

         3. Please indicate the amount of your Claim in the appropriate space on
the face of the Ballot. The amount of your Claim as set forth by you on this
Ballot does not necessarily constitute an Allowed Claim under the Plan. The
amount of your Claim may be subject to further reconciliation and an objection
may be interposed.

         4. After providing all remaining information requested on the face of
the Ballot, please sign, date and return this Ballot by mail or overnight
courier to the voting agent, Logan & Company, Inc. (the "Voting Agent"), at the
following addresses:

                              Logan & Company, Inc.
                                 546 Valley Road
                        Upper Montclair, New Jersey 07043
                           Attn: Philip Services Corp.

         BALLOTS MUST BE RECEIVED BY 5:00 P.M. (PREVAILING EASTERN TIME) ON
OCTOBER 25, 1999 (THE "VOTING DEADLINE"). IF A BALLOT IS RECEIVED AFTER THE
VOTING DEADLINE, IT WILL NOT BE COUNTED. AN ENVELOPE ADDRESSED TO THE VOTING
AGENT IS ENCLOSED FOR YOUR CONVENIENCE.

         5. The Plan can be confirmed by the Bankruptcy Court and thereby made
binding if it is accepted by the holders of at least 2/3 in amount and more than
1/2 in number of Impaired Claims. The votes of the Claims actually voted in your
Class will bind those who do not vote. In the event that the requisite
acceptances are not obtained, the Bankruptcy Court may nevertheless confirm the
Plan if at least one Impaired Class of Claims has accepted the Plan and the
Bankruptcy Court finds that the Plan accords fair and equitable treatment to,
and does not discriminate unfairly against, the Class(es) rejecting it.

         6. You must vote all of your Claims within a single Class to either
accept or reject the Plan. A Ballot that partially rejects and partially accepts
the Plan will not be counted. A Ballot that fails to indicate acceptance or
rejection of the Plan will be counted as an acceptance.

         7. YOUR SIGNATURE IS REQUIRED IN ORDER FOR YOUR VOTE TO BE COUNTED. YOU
ARE ALSO REQUIRED TO PROVIDE YOUR SOCIAL SECURITY NUMBER OR TAX I.D. NUMBER
PRIOR TO RECEIVING ANY DISTRIBUTION. IF THE CLAIM(S) VOTED WITH THIS BALLOT ARE
HELD BY A PARTNERSHIP, THE BALLOT SHOULD BE EXECUTED IN THE NAME OF THE
PARTNERSHIP BY A GENERAL PARTNER. IF THE CLAIM IS HELD BY A CORPORATION, THE
BALLOT MUST BE EXECUTED BY AN OFFICER.
IF YOU ARE SIGNING IN A REPRESENTATIVE CAPACITY, ALSO INDICATE YOUR TITLE AFTER
YOUR SIGNATURE.

         8. This Ballot has been prepared to reflect the Class in which you are
eligible to vote. If you have Claims in more than one Class you may receive more
than one Ballot. IF YOU RECEIVE MORE THAN ONE BALLOT, YOU SHOULD ASSUME THAT
EACH BALLOT IS FOR A CLAIM IN A SEPARATE CLASS AND SHOULD COMPLETE AND RETURN
ALL OF THEM.

         9. The Ballot does not constitute, and shall not be deemed, a proof of
Claim or Equity Interest or an assertion of a Claim or Equity Interest.

                       PLEASE RETURN YOUR BALLOT PROMPTLY

       THE VOTING AGENT WILL NOT ACCEPT BALLOTS BY FACSIMILE TRANSMISSION.
         IF YOU RECEIVED A DAMAGED BALLOT OR LOSE YOUR BALLOT, OR IF YOU
                  HAVE ANY QUESTIONS CONCERNING THE DISCLOSURE
                 STATEMENT, THE PLAN, THIS BALLOT OR THE VOTING
           PROCEDURES, PLEASE CALL THE VOTING AGENT AT (201) 798-1031.
